To Treat And Prevent Breast Cancer

Non-steroidal anti-inflammatory drugs (NSAIDs) can suppress the COX system non-selectively or selectively. Therefore, long-term usage could theoretically reduce breast cancer risk. A number of epidemiological studies have investigated if long-term NSAID reduces breast cancer risk (88-96). Recent meta-analyses and case control studies suggest a moderate reduction in risk of breast cancer with use of NSAIDs of up to 24 (95, 96). This appears to qualify for use of NSAIDs for any duration, and strongest for use lasting greater than 8 years compared to non-users (95). The risk reduction seems to be similar for acetyl-salicylic acid (ASA) containing NSAIDs (such as aspirin or sodium salicylate), and non-ASA NSAIDs (ibuprofen, diclofenac, or indomethacin). Potential weaknesses of all these forms of study include the fact that patients taking NSAIDs may generally be more health conscious, and therefore enter a lower risk group for breast cancer based on lifestyle, and social group, and...

Neutropenia and the Effects of Chemotherapy

Neutropenia can occur by several mechanisms including massive use of neutrophils in the periphery (e.g., in the sepsis syndrome), redistribution of cells including accumulation in the spleen (e.g., rheumatoid arthritis and malaria), and impaired production by the bone marrow. In patients with acute myelogenous leukemia (AML), neutropenia occurs from the expansion of abnormal clone progenitor cells that lack the capacity for full myeloid development. In other hematologic malignancies, neutropenia can occur as a consequence of the disease. In most malignancies, however, neutropenia is attributable to the effects of chemotherapy that reduce myeloid cell proliferation in the bone marrow. With all myelotoxic chemotherapy, the risk of neutropenia depends on the dosing regimen and resiliency of the patient's hematopoietic system. Our understanding of the risk of chemotherapy-induced neutropenia is based on the mechanism of action of the specific drugs and drug combinations, in vivo and in...

Assessing Response To Chemopreventive Agents

Cyclooxygenase (COX) converts arachidonic acid to prostaglandins (PGs), including PGE2. There are two forms of COX COX-1 and COX-2. COX-2 is inducible and upregulation is associated with breast and other cancers. Most COX inhibitors such as aspirin and nonsteroidals block both forms of the COX enzyme. The COX-2 inhibitor celecoxib (celebrex), a medication approved by the FDA to treat osteoarthritis and to reduce the number of intestinal polyps in patients with familial adenomatous polyposis (Steinbach et al., 2000), had a breast cancer preventive effect in preclinical models (Abou-Issa et al., 2001 Howe et al., 2002), lowering PGE2 levels. To assess the ability of celecoxib to lower systemic (plasma) and organ specific (NAF) PGE2 levels, women at increased breast cancer risk were administered 200 mg twice daily. PGE2 levels were 81-fold higher in NAF than in matched plasma. There was not a significant decrease in PGE2 NAF or plasma levels after celecoxib administration. While PGE2...

Pharmacology of Aromatase Inhibitors

Due to the limited specificity of the first- and second-generation AIs, this class of compounds has been neglected therapeutically for a long time. However, recent results from the clinical development of the selective and potent third-generation AIs have provided accumulating evidence that AIs are an alternative endocrine therapy for treating patients with advanced breast cancer. Several randomised clinical trials demonstrated that AIs are superior to tamoxifen in the neo-adjuvant and first-line treatment of advanced breast cancer 73 . Among these, three relevant clinical studies showed that the third-generation AIs, anastrozole, letrozole and exemestane, are superior to tamoxifen in patients with advanced disease. These results led to a series of clinical trials comparing AIs with tamoxifen in the adjuvant setting 82 . Primary objectives of the Arimidex, Tamoxifen, Alone or in Combination (ATAC) trial, were to discover whether anastrozole is at least as effective as tamoxifen in...

Clinical Implications of the Immunosuppression Provoked by the Kynurenine Pathway

Bin1-Amphiphysin2 is a cancer suppressor gene that participates in the traffic control of vesicles and in signal transduction 150, 151 , and the lack of Bin1 expression in some cancers is related to the expression of Indo gene 150 . When Bin1 is repressed, IFN-7 increases STAT1 and NF- B-depen-dent Indo transcription provoking an overproduction of IDO protein, which favors the immune escape of the tumor cells 150 . The enzyme cyclooxygen-ase-2, highly expressed in many tumors 152 , is another possible inductor of IDO 153 , as cyclooxygenase-2 inhibitors suppress IFN-7-mediated IDO expression 154 . It was demonstrated in a mouse model of breast cancer that administration of the cyclooxygenase-2 inhibitor celecoxib decreased IDO expression and improved the response to the tumor. Furthermore, there was a direct correlation between cyclooxygenase-2 and IDO expression in primary human breast cancer specimens, although the clinical significance has not been established yet 153 . As the aim...


Patients with cancer of the esophagus, stomach, colon or rectum, pancreas, lung, breast, cervix uteri, corpus uteri, ovary, prostate, bladder, kidney, and non-Hodgkin's lymphoma, newly diagnosed between 1995 and 2001 (N 48,030), were included for this overview. Patients with cancer diagnosed at autopsy (N 447 or 1 ) were excluded. Treatment was classified as surgery (resection), radiotherapy, chemotherapy, hormonal therapy (or combinations) and 'other or none'. Surgery did not comprise diagnostic operations.

Breast Implants

Capsular Contracture

Silicone and saline implants are radio-opaque on mammography and have led to concerns regarding potential delay in breast cancer detection.39-40 Implant characteristics, which may affect the sensitivity of standard mammo-graphy, include implant size, the proportion of overlying breast tissue, implant placement (subglandular versus submuscular) and the presence and immobility of capsular contracture.41-42 As recommended by the American Cancer Society and the American Society of Plastic and Reconstructive Surgeons, women with breast implants should maintain the same schedule of mammography as all other women. They should secure a certified facility that has sufficient experience with breast implants and confirm the availability of displacement mam-mography (Eklund) and ultrasound. Patients with postmastectomy implant reconstruction are typically followed by physical examination only. One major epidemiologic study has confirmed that the stage at breast cancer detection in women with...

Examples From Other Areas

In a recent article, Gustafson et al.50 presented the first randomized outcome evaluation of an Internet health information support system for patients. Their CHESS (Comprehensive Health Enhancement Support System) interactive computer support system, which has also been applied with breast cancer, heart disease and problem-drinking patients, was evaluated for its ability to provide support for HIV-positive patients. Half of the 204 patients had computers linked to the CHESS system placed in their homes for 3 or 6 months controls received no intervention beyond usual care. The CHESS system was used daily, and produced significant improvements in several quality-of-life dimensions and fewer and shorter hospita-lizations than were seen in control patients.

Putative copper indicators

Serum copper is known to be altered by a number of factors not directly related to copper status. Concentrations are low in infancy and rise to adult levels over the first 4-6 months, or longer following a low birth weight. In adult women, serum copper concentration is generally higher than in men, and is further raised during pregnancy and by oestrogen treatments.54 There is also a normal diurnal variation with a slight peak in the morning. Plasma copper fluctuates with age, and is raised in a number of other conditions including exercise, rheumatoid arthritis, dilated cardiomyopathy and anticonvulsant chemotherapy. Between 60 and 95 of serum copper is associated with caeruloplasmin, so serum copper levels often mirror those of caeruloplasmin.11

Adapted from Thompson

Small bowel epithelium, itself increased fourfold, resulting in flattening of the villi (Moss et al., 1996) and a range of symptoms characteristic of active coeliac disease, due to a failure to hydrolyse food macromolecules and absorb the constituent monomers. Consumption of gluten-free diets returned small intestinal apoptotic scores to normal (Moss et al., 1996). Apoptosis may be de-regulated in other intestinal disorders characterized by 'flat' lesions and induced, for example, by chemotherapy or by deficiencies of folate or vitamin B12 (Lewin and Weinstein, 1996). An abnormally high rate of intestinal mucosal cell apoptosis may contribute to the pathophysiology of ulcerative colitis (Strater et al., 1997). The development of AIDS (acquired immunodeficiency syndrome) is strongly correlated with the depletion of CD4+ T cells, which undergo apoptosis when the soluble viral product gp120 binds to the CD4 receptor (Thompson, 1995). Increased cell death by apoptosis may be involved in...

Series Editor Introduction

The second section examines the importance of Preventive Nutrition to primary and secondary cancer prevention. The chapter on diet and childhood cancers updates the findings from the first edition and concludes that this area remains one where the data from survey studies are suggestive, but not as yet conclusive concerning the benefit of multivitamin use during pregnancy and reduced risk of two of the major childhood cancers, leukemia, and brain tumors. There is an insightful evaluation of the differences between the timing of cancer development in childhood, especially young childhood cancers versus adult cancer development. Virtually all the epidemiological studies of maternal diet, supplement use, and major childhood cancers have been tabulated for the reader. Gastric and esophageal cancers are closely related to lifestyle factors, including alcohol and tobacco use chronic consumption of very hot liquids salted, pickled, and smoked foods and obesity. The link between Helicobacter...

The Context Of Diagnostic Labels

Finally, a fuller understanding of the genetic basis of certain conditions has further implications for the process of diagnostic labeling. The discovery of the BRCA gene in a currently asymptomatic individual is a marker for the potential development of breast cancer. An estimate of the probability for developing clinically identifiable cancer may be made, but what remains unclear is the point at which the transformation between carrier and patient takes place. Women carrying this gene who elect to undergo bilateral prophylactic mastectomies are, for all purposes, patients with breast tissue that is in a precancerous state despite the absence of a tissue diagnosis other than the genetic marker. Diagnostic

Illustrative Case Vignettes

Depression after admission for new-onset seizures and was found to have a right frontoparietalsubarrachnoid hemorrhage. She also had end-stage renaldisease due to polycystic kidney disease and was on hemodialysis. She had a history of pancreatic carcinoma treated with radiation therapy and chemotherapy. Ms. A was found to have mild dementia with anosognosia and mood disorder as a result of complex medicalillnesses. She responded wellto support.

Overcoming The Hurdles With New Technologies

Regulatory review is also speeding up. FDA approval for Herceptin (triatuzumab), a humanized monoclonal antibody against the tyrosine kinase receptor erbB2, was obtained in a record 4.5 mo (51). Arguably the first molecular target therapy based on cancer genom-ics, this agent shows promising activity in breast cancer.

Morbidity Associated With Klinefelters Syndrome

Data from large population-based studies of chromosome abnormalities at birth have demonstrated that the KS occurs in approx 1 in 400-600 male births (30-32). In adults, overall age-matched mortality is roughly doubled (33,34). Most of this increase is from non-neoplastic diseases of the cardiovascular, respiratory, and digestive systems, and diabetes however, the incidence of breast cancer and autoimmune disease is also increased (35). The risk of breast cancer is 20-fold higher in men with KS, who account for 4 of all breast cancer cases in men. Fortunately, breast cancer in men is rare, so the absolute risk of breast cancer in an individual with KS is well under 1 , and screening with mammography is not generally recommended (36). There is also an increased risk of extragonadal germ cell tumors in individuals with KS (37). Affected patients are young and frequently present with advanced disease, often of the mediastinum. It is believed that these neoplasms arise from primordial...

Lymphoproliferative Disorders 51 Lymphomas

Asherson et al. 80 subsequently reported a female with a history of polyarthralgias who developed SLE and lymphoma simultaneously. The lymphoma responded well to chemotherapy and steroids. She then developed an arterial occlusion resulting in amputation of a toe, TIA, livedo reticularis and thrombocytopenia (68 x 109 1). aCL (IgM isotype) was positive and a biological false test for syphilis was also demonstrated subsequently. The activity of the SLE in this patient appeared to increase after cessation of chemotherapy for the lymphoma.

Regulatory Dossier ready for submission

By 2010 one-fifth of Italy's population will be over 65, causing a dramatic expansion of the healthcare market 80 of an individual's lifetime healthcare costs are incurred after the age of 75. Strategic marketers in the pharmaceutical industry are following this trend with a resultant massive concentration of R&D effort towards the afflictions of this group depression, dementia Alzheimer's, Parkinson's, stroke, diabetes, osteoporosis, rheumatoid arthritis, breast cancer, melanoma, ischemic heart disease, incontinence, postural hypotension etc.

Pathological Significance of Human Collagenase3

To date, human collagenase-3 expression has been associated with two pressing pathological conditions cancer and arthritic diseases. In fact, collagenase-3 was originally identified as an enzyme produced by mammary carcinomas,1 but further studies have extended its participation to other tumor processes distinct from breast cancer. In addition, the relevance of collagenase-3 as a degradative enzyme in joint diseases has been the focus of notable interest, with a number of papers examining distinct aspects of this connection 9,10,12-15,70 The first studies linking collagenase-3 to tumor processes were performed by Freije et al,1 who detected the expression of collagenase-3 mRNA in some breast carcinomas but not in benign lesions or unaffected normal mammary gland. This expression analysis also revealed three different mRNA species in breast carcinomas which result from the alternative use of different polyadenylation sites in the 3'-flanking region of the collagenase-3 gene. In situ...

Autoantibodies In Malignant Diseases

Including 113 cancer patients, the incidence of positive ANA test was 27 compared with 2 in the control group 34 . Likewise, Zermosky et al. 35 found positive ANF test in 13 of patients with various malignancies. Increased prevalence of ANA was reported in epithelial tumors including carcinoma of the breast, prostate, melanoma, hepatocellular carcinoma and leukemias 35-42 , The antinuclear antibodies produced in malignancies differ from those that characterize SLE. In SLE the antinuclear antibodies are typically directed against many nuclear antigens including ssDNA, dsDNA, Sm and RNP. However, in malignancies the spectrum of antinuclear antibodies described is more limited for example in one study of patients with lymphomas and leukemias only anti-ssDNA antibodies were described. We studied 84 patients with Hodgkin's lymphoma and 55 with non-Hodgkin's lymphomas for the presence of autoantibodies to ssDNA, dsDNA, Poly (I), Poly (G), cardiolipin, histones, RNP, Sm, Ro, La and the...

Studies on the Role of Exercise Fitness in the Etiology of Other Diseases

In general, data relating to associations between physical activity and breast, endometrial, ovarian, prostate, and testicular cancers are inconclusive, although the suggestion that activity in adolescence and young adulthood may provide subsequent protection against breast cancer is worthy of further study. To date, the only clear evidence in this field comes from epidemiological studies relating a reduced risk of cancer of the colon to both occupational and leisure time physical activity. One such study investigated 17148 Harvard alumni, who

Other Temporary Pacing

Treatment of tumors of the head and or neck or around the carotid sinus may in some circumstances give rise to high-grade AV block. Temporary pacing may be required during surgical treatment, radiation therapy, or chemotherapy. If the tumor responds poorly, permanent pacing may be necessary in some cases. The long-term risk for subsequent heart block due to tumor recurrence is difficult to predict in some cases.

Paraneoplastic Arthropathies Of Solid Tumours

Lignancy and remission were found and in addition no correlation was noted between tumour location and development of arthritis. However, breast cancer was by far the most common cause of an asymmetrical arthritis in women 6 . Analysis of an additional 12 cases revealed symmetric arthritis and a positive rheumatoid factor in 10 and 6 patients, respectively. Therapy of the tumour resulted in complete disappearance of the joint symptoms in 9 of the 12 patients and amelioration was achieved in the remaining 3 patients. The arthropathy antedated discovery of the tumour from 15 days to 18 months. Although the late age at onset of arthritis was suggested as a typical feature of cancer arthritis, in this series of 12 patients the youngest was a 36-year-old man who suffered from testicular seminoma 7 . Another case of a 21-year-old man was reported in which symmetric polyarthritis antedate a discovery of a malignant fibrous histiocytoma of the heart by 5 months 8 . Besides the late age at the...

Health Benefits of

As with prostate cancer in men, epidemiological data suggests that soy-rich diets reduce the incidence of breast cancer in women (48,49). Decreased risk of breast cancer has been associated with lifelong consumption of plant foods containing estrogenic compounds, particularly soy isoflavones (55). Data collected in the Shanghai Breast Cancer Study suggested a protective effect of

Other biological activities of IL1

IL-1 is an important regulator of hematopoiesis, although the phenotype of IL-ip-deficient mice is remarkably normal. IL-1 induces the production of CSF by bone marrow stromal cell and receptors for CSF. Thus IL-1 synergizes with CSF to stimulate growth of early hematopoietic bone marrow progenitor cells and can counteract the myelosuppress-ive effects of radiotherapy and chemotherapy. The latter effect is mediated partly through the induction of mitochondrial manganese superoxide dismutase

Hodgkins Lymphoma And

Historically, clinical outcomes of patients with HIV-associated HL have been poor, with patients experiencing frequent infectious complications, and a more aggressive disease process. However, a recent report from Italy described 59 patients receiving combination chemotherapy with highly active retro-viral therapy (HAART) and granulocyte colony-stimulating factor (G-CSF). Patients were treated with the Stanford V combination chemotherapy, which was well tolerated in 69 of patients completing treatment without dose reduction or delay in chemotherapy administration. Complete response was achieved by 81 of patients, and 56 were alive in remission with a median follow-up of 17 months. The authors concluded that in the era of HAART and G-CSF support, the delivery of combina tion chemotherapy to HIV-infected individuals is more feasible and more effective than seen previously.42

Prosthetic Joint Replacement

The main treatment consideration for patients with prosthetic joint replacements relates to the potential need for antibiotic prophylaxis before periodontal therapy. Currently, there is no scientific evidence that prophylactic antibiotics prevent late prosthetic joint infections, which might occur from transient bacteremia induced by dental treatment.16 Furthermore, although dental-induced bacteremia could theoretically cause prosthetic joint infection, very few reports demonstrate dental treatment as a source of joint infection, and none of these actually document a cause-and-effect relation-ship.13,67 Thus the Xmerican Dental Association, American Academy of Orthopaedic Surgeons, American Academy of Oral Medicine, and British Society for Antimicrobial Chemotherapy all agree that routine antibiotic prophylaxis before dental treatment is not indicated for most patients with prosthetic joint replacements.uu,

Indications and Patient Selection for Bariatric Surgery

Hypercoagulapathy, female hormonal dysfunction such as amenorhea, dysmen-orrhea, infertility, hypermenorrhea, increased incidence of breast cancer, uterine, colon, prostate and other cancers and debilitating joint disease involving hips, knees, ankles, feet and lower back are common in these patients. In addition, obese patients clearly experience a multitude of difficulties related to social acceptance in society, work-related problems, body image, reduced mobility, sexual dysfunction and other psychosocial problems that add more pathology to this chronic and deadly disorder. The difficulties in diagnosing and treating surgical conditions in obese patients such as peritonitis, necrotizing panniculitis, necrotizing fasciitis, diverticu-litis, necrotizing pancreatitis and other intra-abdominal infectious catastrophes are significant.

Current Treatments

Estrogen deficiency, due to menopause, amenorrhea, chemotherapy, or excessive exercise, is associated with precipitate trabecular bone loss. This is due at least in part to increased osteoclastic activity, which occurs via increases in proresorptive cytokines, e.g., IL1 and IL6, and RANKL, and decreases in antiresorptive factors, such as OPG. Whilst HRT ET results in increases in BMD and decreases in fracture incidence, long-term treatment is associated with several side effects, including cardiovascular events, uterine bleeding, and increased risk of breast cancer. Tamoxifen (Figure 7), the prototypical member of the SERM family, exhibits estrogen-like effects on the skeleton, reducing bone loss and fracture incidence but, in contrast to ET, has antiestrogen effects on breast tissue, leading to its therapeutic use in treating breast cancer. Tamoxifen treatment is also associated with decreases in serum low-density lipoprotein cholesterol. Whilst it is an improvement over using ET,...

Data from Russian Clinical Childrens Hospital

Fifteen and eight patients had infections of respiratory tract and gastrointestinal tract, respectively. Herpes simplex infections with frequent relapses were observed in seven patients while candidiasis superficialis in 12 patients (five of which were after chemotherapy). Lymphoid tissue hypoplasia was observed in one child and hyperplasia of lymph nodes with hepatosplenomegaly was detected in 13 patients seven of them had lymphoid tissue malignancies. Different cytopenias were identified in 10, bone marrow aplasia in 2, vasculitis in 2, and vasculitis + arthritis in 1 patient. Different malignancies developed in eight cases embrional rhabdomyosar-coma (1), acute myeloid leukemia (2), Hodgkin disease (1), and B cell leukemia or B lymphoma (4 cases).

Analytic Epidemiology

Ionizing Irradiation and Chemotherapy Slightly lower risks of CML were seen in patients treated for ankylosing spondylitis either by external beam therapy54 or radium-224.55 Other case series treated with radiation also occasionally show excess of CML, for example, those treated for cervix cancer10 or for benign uterine bleeding.56 Most other therapy-related cohorts are too small to be likely to reveal a risk of CML after follow-up. Similarly CML is very rarely reported as a secondary outcome of chemotherapy for primary cancers. This does not preclude CML as a possible outcome, but if it is the risk is very low.57

Immediate Questions

What medication(s) does patient take Aspirin and NSAIDs may lead to GI blood loss. Chemotherapy drugs, immunosuppressives, folate antagonists (trimethoprim-sulfamethoxazole), anticonvulsants (carbamazepine, valproate, dilantin), and anti-inflammatory drugs (phenylbutazone) may cause marrow suppression or aplasia. Penicillin, sulfonamides, or oxidants may cause hemolysis. Alcohol, isoniazid, and trimethoprim may cause maturation defects.

Long Term Effects Tumorigenicity

The overall incidence of reproductive cancers attributable to oral contraceptive use has been estimated in a modeling analysis (66). The authors assumed a 50 reduction in ovarian and endometrial cancers associated with 5 years or more of tablet use, and used two alternative scenarios for breast and cervical cancer effects. If oral contraceptive use produces a 20 increase in breast cancer before age 50 and the same increase in cervical cancer, then for every 100 000 tablet users there would be 44 fewer reproductive cancers and these users would gain one more day free of cancer. If instead the increase in risk of early breast cancer and of cervical Some helpful evidence comes from related fields. It should be borne in mind, for example, that the question of an increased risk of endometrial hyperplasia and endometrial cancer also arises in patients with estrogen-producing tumors of the ovaries, obesity, and polycystic ovarian syndrome (94) and in patients with breast cancer who are using...

Antimetastatic Agents

A primary tumor is often not the direct cause of death of a patient because it can be removed by surgery and treated with radiotherapy or chemotherapy. Rather, secondary tumors (metastases) usually lead to death because they become too dispersed throughout the body to make further treatment, particularly surgery, possible. Therefore, there is interest in identifying agents capable of inhibiting the mechanism by which tumor cells move around the body, either via the blood or the lymph system, to establish themselves in new locations.

Alternative delivery

In HIV hair loss can result from use of drugs for treatment of the virus in some individuals. Alopecia also occurs in other diseases that use similar strong chemotherapy. Other types of alopecia are caused by a variety of skin and hair follicle diseases. They can all occur in men, women, and children.

Clinical Implications

The ability to modulate the stress response also has therapeutic implications as it relates to cancer. The increased expression of hsp 28 and hsp 72 has been associated with enhanced survival of tumor cells subjected to some cancer che-motherapeutic agents (reviewed in ref. 31). The increased expression of the multidrug resistance protein (MDR), whose corresponding gene contains an appropriate heat shock element, has been clearly shown to underlie the development of resistance to many cancer chemotherapeutic agents (reviewed in ref. 32). Thus, finding a way by which to downregulate or even prevent the expression of stress proteins in malignant cells may enhance the efficacy of many chemotherapeutic agents. Such an advance might allow the use of lower doses of chemotherapy, and thus perhaps minimize the toxic side effects of these agents on normal cells. In preliminary experiments, a flavonoid compound, querecetin, reported to be an inhibitor of protein kinases, was shown specifically...

In Vitro JNK Kinase Assay 14

The JNKs are stress-activated protein kinases (29,30). The JNKs bind and phosphorylate c-Jun, a component of the AP-1 transcription complex, and increase its transcriptional activity (7,31,32). AP-1 is involved in regulation of many cytokine genes and is activated in response to environmental stress, radiation, and growth factors, all stimuli that activate JNKs. The inhibition of JNKs enhances chemotherapy-induced inhibition of tumor cell growth, suggesting that JNKs may provide a molecular target for the treatment of cancer. JNK inhibitors have shown promise inhibiting tumor cell growth and in the treatment of rheumatoid arthritis (5).

Applications of Hypnosis

Research on altered states of consciousness has led to many benefits. The analgesic properties of hypnosis were verified in research conducted by Ernest Hilgard at Stanford University. He found that hypnotic suggestion could be used to reduce or eliminate experimentally induced pain. Even though subjects were not consciously aware of the pain, Hilgard found that, with the right questions, he could uncover a hidden observer, a dissociated aspect of the subject's conscious awareness that did monitor the feelings of pain. Hilgard reports that hypnotic relief from pain has been reported for the chronic pain of arthritis, nerve damage, migraine headaches, and cancer. For individuals who are unable to be anesthetized because of allergic reactions or fear of needles, hypnosis is often used as an effective substitute for the control of pain. It has been effectively applied in cases involving dental work, childbirth, burns, abdominal surgery, and spinal taps. Hypnotic suggestion has also been...

Obesity Recognition and Treatment in Women

The increased health risks of obesity include hypertension, elevated serum cholesterol and death related to cardiovascular diseases as well as diabetes, gallbladder disease, osteoarthritis, carpal tunnel, sleep apnea, respiratory problems and endome-trial, breast and colon cancers. Specific to the obstetrician gynecologist, obesity is associated with both increased gynecological and obstetrical morbidity. Major gynecological problems include abnormal uterine bleeding, ovulatory dysfunction and endometrial cancer. Adult weight gain is associated with increased risk for breast cancer in postmenopausal women. An overweight individual undergoing surgery has an increased risk of excess blood loss, increased operating time and longer exposure to anesthesia and infection. Obesity in pregnancy increases the risk of gesta-tional hypertension, preeclampsia gestational diabetes, fetal macrosomia and cesarean delivery. Obesity is an independent risk factor for spontaneous abortion and pregnancy...

Diabetes mellitus 141

Dexamethasone A synthetic steroid hormone, similar to those produced by the adrenal glands. Like other corticosteroids, dexamethasone has a wide range of biological actions. It is used most frequently for its anti-inflammatory effects, but it is also a potent inhibitor of certain immune responses. Dexamethasone is used to treat a variety of conditions, including arthritis and other rheumatic diseases, connective-tissue disease, respiratory disease, skin disorders, allergic reactions, inflammation of the eyes, certain blood disorders, inflammation of the brain, and, as a palliative, in certain cancers. In people with HIV it is commonly used alone to counteract allergic drug reactions and as part of a combination chemotherapy for the treatment of AIDS-related lymphoma. Dexametha-sone is available in a number of formulations, including tablets or liquid, topical creams or lotions, ointments for administration to the eyes, inhalants, and as a solution for injection. Stomach upset,...

Preface to the Third Edition

In addition to coverage of the colony-stimulating factors G-, M- and GM-CSF, two new chapters in this edition are afforded to individual hematopoietic cytokines - stem cell factor (SCF) (c-kit ligand) and flt-3 ligand - that have many biological functions in common. SCF is a potent costimulatory or synergistic factor in cytokine cocktails for manipulation of hematopoietic cells. It appears to be of value in the combination of ex vivo 'expansion' technologies with gene transfer methods for the correction of genetic disease or the support of multiple chemotherapy cancer patients. The recently cloned cytokine flt-3 ligand has been shown to dramatically increase the numbers of functional dendritic cells and also to increase natural killer cells in vivo. Moreover it exerts anti-tumor activity, raising expectation of a future role of this molecule as a human immunotherapeutic agent.

Treatment and Outcome

Infective endocarditis This is an infection of the inner lining of the heart, usually involving one of the valves that controls the flow of blood through the heart. Of people who develop infective endocarditis, 75 percent have a previously damaged heart valve. This can be following previous rheumatic fever, an aortic valve with two rather than the normal three cusps, a leaking mitral valve (mitral valve prolapse), congenital heart disease, or an artificial heart valve. others at risk of developing infective endocarditis include intravenous drug users and those with long-standing intravenous lines for various reasons such as intravenous feeding and chemotherapy.

Expanding Applications for Hematopoietic Cell Transplantation

Autoimmune disease Autoimmune diseases are a heterogeneous group of disorders with genetic and environmental etiologies which occur when there is a breakdown in the immune systems tolerance to normal tissues. The most common autoimmune diseases are rheumatoid arthritis, systemic lupus erythemetosis (SLE) and type I diabetes mellitus. Pathophysiology generally involves persistent manifestations of chronic tissue damage, as cells of the immune system recognize self-antigens on target tissues as foreign. Early experiments demonstrated that bone marrow transplantation could alter the course of autoimmune diseases in animal models.107 BMT was shown to transfer disease from autoimmune prone animals to unaffected ones, but also to prevent disease if hematopoietic cells were transplanted from unaffected rodents to susceptible ones.108 Purified HSC from diabetes-resistant donors transplanted to just-diabetic NOD mice have been shown to permanently prevent progression to autoimmune diabetes...

Sex Chromosomal Abnormalities

Affected children have small, firm testes, and adult patients have azoospermia. y This disorder is a common cause of primary hypogonadism and male infertility. Although a male phenotype is typical, delayed or poorly developed secondary sex characteristics are present, and about half the patients have varying degrees of gynecomastia, androgen deficiency, and eunuchoid features. These patients tend to be tall and have long legs, and adults have an increased incidence of pulmonary disease, varicose veins, diabetes mellitus, and breast cancer. y Serum levels of follicle-stimulating hormone and luteinizing hormone are increased early in the second decade, whereas testosterone concentrations are normal to low. Plasma levels of estradiol are normal or high. Affected individuals have cognitive abnormalities including impaired auditory sequential memory with delayed language development and associated learning disorders. y There is a slight lowering of the mean IQ and an increased incidence of...

Disease considerations

In November 2000, the Centers for Disease Control and Prevention released a report on the health and economic burden of chronic disease.56 Seventy percent of Americans who die do so of a chronic disease. For women aged 3564 years old, cardiovascular disease, lung cancer, and breast cancer are the three leading causes of death. One-sixth of the American population has arthritis, the primary disabling disorder. Fifty percent of individuals with osteoporosis cannot walk unassisted and 25 require long-term care. Clearly, there is a need for exercise intervention to help mitigate the effects of aging, to prevent chronic disease, and to enhance quality of life.

Uric Acid Nephropathy

Uric acid nephropathy is caused by precipitation of uric acid crystals in the renal tubules. It is usually due to a sudden overproduction of uric acid in a dehydrated patient (e.g., following vigorous exercise).21 Uric acid nephropathy can also be seen in patients with aggressive leukemia or during chemotherapy leading to rapid cell turnover. Uric acid nephropathy can be treated with vigorous hydration, diuretics, and alkalinization of urine prevention is often possible if patients at risk are kept well hydrated.

Entitled to Respect A National Survey of Teens Attitudes and Behaviors About Epilepsy and Acceptance Executive Summary

Summary Entitled to Respect A National Survey of Teens' Attitudes and Behaviors About Epilepsy and Acceptance Executive Summary summarizes the results of a survey of teens' attitudes and behaviors about epilepsy. The survey consisted of a questionnaire that was distributed to teens throughout the United States by 20 affiliates of the Epilepsy Foundation from March through July 2001 in schools selected by the affiliates. The questionnaire asked about respondents' (1) demographics (2) awareness of epilepsy (3) knowledge of epilepsy (4) perceived stigmas associated with epilepsy and (5) awareness of muscular dystrophy, human immunodeficiency virus infection acquired immunodeficiency syndrome, arthritis, diabetes, breast cancer, and Parkinson's Disease. Results are based on 19,441 usable questionnaires. Thirty-six percent of the respondents felt that kids with epilepsy are likely to get picked on or bullied more than other kids. Only 25 percent felt this is unlikely to happen. Thirty-one...

Somatostatin Analogs New Perspectives

Acromegaly and so-called neuroendocrine tumors (carcinoids, pancreatic endocrine tumors) are at present the only routine indications for somatostatin (SST) analogs therapy. However, the progress in the studies on somatostatin receptors (sst) and the development of the numerous new SST analog molecules, creates new possibilities of the therapeutic applications. These possibilities include (1) the treatment of pituitary tumors other than those connected with acromegaly (2) the treatment of non endocrine cancers, including so-called receptor-targeted chemotherapy (3) the treatment of autoimmune chronic inflammatory disorders, including Graves' ophtalmopathy and rheumatoid arthritis and (4) the treatment of diabetic retinopathy and senile macular degeneration.

Extrapulmonary Tuberculosis

Patients with suspected tuberculous pleurisy should undergo PPD skin testing and examination of the sputum and pleural fluid. Many patients with minimal parenchymal disease will have negative sputum smears due to the low bacillary burden. Sputum and gastric aspirate AFB smears are positive in less than one-third of patients.83 AFB smears of pleural fluid also have a low diagnostic yield and mycobacterial cultures are positive in less than 25 .83,89 Closed pleural biopsy with the Abrams' or Cope's needle is a very useful diagnostic technique. The presence of granulomas in pleural tissue, even in the absence of AFB or caseation, is highly suggestive of TB. A single pleural biopsy will demonstrate granulomas in approximately 60 of cases.90 If multiple biopsy specimens are examined, the diagnostic yield increases to approximately 90 . Portions of the biopsy material should be submitted for histologic evaluation and special stains and other portions should be cultured. AFBs are seen in...

New Sense Of Danger

Although most studies on extracellular HSP in cancer concentrate on cell surface expression, HSP release from tumor cells has also been shown to reduce tumor cell survival (Wang et al., 2004). Hsp72 has important roles in the protection of cells against apoptosis, an undesirable property in tumor cells (Gehrmann et al., 2005 Thomas et al., 2005 Wang et al., 2004). High levels of Hsp72 in cancer cells protect the cells against radiotherapy and chemotherapy and are therefore detrimental to the patient (Gehrmann et al., 2005 Thomas et al., 2005 Wang et al., 2004). Release of Hsp72 from tumors may be important in two ways Firstly by lowering intracellular Hsp72 and therefore reducing protection against apoptosis, and secondly by increasing extracellular HSP that may be important in immune responses against tumors (Wang et al., 2004). Hsp72 release can be induced in human prostate cell lines (Wang et al., 2004) and an epidermoid carcinoma cell line (Evdonin et al., 2004), suggesting...

Neurotransmitters and Their Receptors

** Diseases affected by these processes. 1 Prostate cancer, 2 breast cancer, 3 HI HA syndrome, 4 diabetes, 5 obesity, 6 cardiovascular diseases EGCG decreases plasma levels of several hormones, including the sex hormones testosterone, 17P-estradiol, and luteinizing hormone, as well as leptin, insulinlike growth factor I (IGF-1), and insulin 41 . (For other such effects of EGCG on the endocrine system, see Table 9.3.) Weights of androgen- estrogen-sensitive organs (prostate, seminal vesicles, uterus, ovaries) decreased within 7 d of intraperitoneal EGCG injection in rats. Most effects in males were not solely dependent upon lowered testosterone levels since exogenous androgens did not reverse them. Decreased levels of sex hormones may lower risk of development of prostate and breast cancer. Several Asian countries do indeed report low incidence. Additionally, low levels of EGCG increase estrogen stimulation of the estrogen receptor a, expressed on the ovaries, uterus, vagina, and...

Factors Associated with Risk for Colorectal Cancer

In women, HRT has been shown to protect against colorectal cancer. Numerous observational studies have shown an association between recent and prolonged use of HRT in postmenopausal women and decreased incidence of colorectal cancer. Recently, a controlled trial of HRT conducted by the Women's Health Initiative showed a 38 decrease in the incidence of colorectal cancer after 5 years of HRT use. Before HRT can be considered indicated for colorectal chemoprevention, its protective effect against colorectal cancer must be weighed against the increased risk of breast cancer and thromboembolism.

PRL Clinical Implications

Suggested (Brennan, Ollier, Worthington, Hajeer, and Silman 1996), as well an involvement of PRL in the development and progression of leukemia and lymphoma. PRL may promote the growth of hematopoietic cancers. In fact, elevated serum PRL was detected in more than 50 of patients with acute myeloid leukemia (Hatfill, Kirby, Hanley, Rybicki, and Bohm 1990), although this observation might be the result of an associated stress response. There is, to date, no disease known to cause by mutation of the PRLR, or even of its ligand. Interestingly, in vitro studies have shown that antihuman PRL antibodies can prevent proliferation of breast cancer cell lines induced by locally produced PRL (Ginsburg and Vonderhaar 1995).

Raloxifene hydrochloride

Action Kinetics Selective estrogen receptor modulator that reduces bone resorption and decreases overall bone turnover. Considered an estrogen antagonist that acts by combining with estrogen receptors. Has not been associated with endo-metrial proliferation, breast enlargement, breast pain, or increased risk of breast cancer. Also decreases total and LDL cholesterol levels. Absorbed rapidly after PO significant first-pass effect. Excreted primarily in feces with small amounts excreted in urine.

Pain And Spiritual Activity

As people age, they usually develop chronic diseases (e.g., cataracts), some of which can be painful (i.e., degenerative joint disease). In addition, eventually all succumb to a terminal illness, which may be painful (e.g., prostate or breast cancer with bone metastases). However, spiritual

PUFA Omega6 and Omega3 Fatty Acids n6 and n3 FA

Symptoms of essential fatty acid deficiency may include fatigue, skin problems, immune weakness, gastrointestinal disorders, heart and circulatory problems, growth retardation, and sterility (Belzung et al., 1998). In addition to these symptom conditions, a lack of dietary essential fatty acids has been implicated in the development or aggravation of breast cancer, prostate cancer, rheumatoid arthritis, asthma, preeclampsia, depression, schizophrenia, and ADHD (attention-deficit hyperactivity disorder). The list is neither exhaustive nor conclusive.

Estrogen and Progesterone Receptors

In the United States and other western societies, approximately one in 10 women develops breast cancer. Given the unacceptably high mortality rate of approximately 40 , it is critically important that the most effective therapy at any given time is administered to each patient. Although both adjuvant chemo- and hormonal therapies reduce the risk of metastasis by approximately one-third, the best indicators for clinical progression available today, including lymph node status, tumor size and histological grade, are unable to accurately predict the outcome. The presence of estrogen and or progesterone receptors on tumors is considered favorable because these patients are eligible for hormonal treatment. Tamoxifen, is a selective estrogen-receptor modulator (SERM), which acts as an estrogen antagonist in normal breast tissue and breast cancer cells but as an antagonist in liver and bone cells. Apart from lowering serum cholesterol and preventing postmenopausal osteoporosis (26),...

Diagnosis And Clinical Features

Leukemic cells lysed by induction chemotherapy also release potassium into the extracellular space. This becomes a concern especially in the setting of inadequate renal clearance, when serum potassium concentration can rise to dangerous levels and result in cardiac arrest.25 Hypokalemia may occur in the setting of acute monoblastic leukemia in which lysozyme release acts at the level of kidneys to cause potassium depletion.

Whats Wrong with the Lab Tests

If you go to your doctor to have your thyroid tested, he or she will draw your blood and send it to the lab to obtain a thyroid panel. While the advances made in diagnosing diseases in the laboratory have been remarkable over the last decade, as can be seen in the tests for illnesses such as rheumatoid arthritis and breast cancer, lab tests for hypothyroid problems are still largely inaccurate, according to Dr. Charles Mary III of the Mary Clinic in Louisiana. Dr. Mary's position was backed up by the majority of doctors attending the recent Consensus Development Conference.

Attacking Wntfzd Interface

To date, we are far from understanding the WNT-FZD interaction and attempts at screening for compounds that interfere with WNT-FZD binding are hampered by difficulties with WNT purification, the lack of suitable FZD expression systems, and the lack of selective radioligands. Recently, a WNT-5A - mimetic formylated peptide (formyl - Met - Asp - Gly - Cys - Glu - Leu) was described 104 . The peptide was shown to affect cell adhesion and migration in cancer cell lines through FZD5, suggesting its use as an antimetastatic agent, for example, for human breast cancer patients. In addition to its promising potential as a therapeutic agent, this peptide could also be used as a tool to screen for small- molecule ligands that compete for binding sites. A similar short synthetic peptide was described for WNT-1, which promoted cell adhesion and hippocampal neural stem cell differentiation 105 - With regard to solubility, stability, administration, and drug distribution, a small-molecule ligand...

The role of eicosanoids in tumor promotion

In animal experiments overproduction of prostaglandins by tumors and an anti-tumor effect of NSAIDs have been shown for a variety of tissues including the intestine, epidermis, esophagus, lung, urinary bladder, kidney, stomach and mammary gland (for a review, see Marnett 41 ). Excessive prostaglandin levels were also found in various tumors of man, for instance in mammary tumors (see, for instance, Robertson et al. 50 ). However, as far as the chemopreventive effect of NSAIDs on tumors outside the gastrointestinal tract is concerned, the clinical and epidemiological evidence is still controversial. Indeed, both a prospective and a case-control study revealed a statistically significant reduction in breast cancer in women who had regularly taken aspirin or ibuprofen 80,81 , whereas other authors did not observe such an effect 82-85 . The evidence for chemoprevention of lung cancer by NSAIDs is even less significant 80 , On the other hand, a rather strong correlation was found for...

Proteins of the Peroxiredoxin Based System as Diagnostic and Prognostic Tools and Potential Drug Targets

Nonetheless, it has recently been shown that Trx 1 function strongly depends on subcellular localization. Chen et al. 138 demonstrated that only MCF7 breast cancer cells with an increased nuclear Trx 1 content were resistant to cisplatin-induced apoptosis. In contrast, an increase in total Trx 1 level, unaccompanied by an increase of nuclear Trx 1, did not protect the cells from apoptosis 138 . The authors suggested that nuclear Trx 1 acts by upregulating p53 138 .

Lymphatics in Disease Lymphedema and Cancer Cancer

Lymphatic vessels are known to play an essential role in the expansion and dissemination of several forms of cancer. Whereas malignancies of mesenchymal origin frequently spread via the blood vascular system, carcinomas more often migrate and pass through the lymphatic system. Many models now describe a near absence of metastasis in animals devoid of or deficient in lymphatic vessels and establish that many forms of cancer, most notably breast cancer, are lymphatic dependent. Many tumors (e.g., gastric carcinoma and pancreatic and invasive lung adenocarcinomas) secrete lymphatic specific growth factors such as VEGF-C and -D and represent significant risk factors for tumor progression. These studies showed a high risk associated with VEGF-C expression in tumor status. Besides its role in solid tumor progression, Flt-4 may also play roles in leukemia as well, since several leukemia cell lines express Flt-4. Furthermore, findings that many lymphatic markers such as VEGF-R3 and podoplanin...

Determinants of S aureus Infection

The involvement of host factors may also be inferred from known risk factors for S. aureus disease. For example, the onset of septic arthritis after closed joint trauma is well recognized, and there is an increased risk of S. aureus septic arthritis in those with inflammatory arthritides such as rheumatoid arthritis. Diabetes mellitus is associated with a higher risk of S. aureus infection, but the relative importance of factors such as higher S. aureus carriage rate, relative immunodeficiency and repeated needle puncture is uncertain. Immune dysfunction may also be an important contributor to the higher rate of S. aureus sepsis in patients undergoing chemotherapy for malignant disease or haemodialysis. The presence of surgical incisions and prosthetic devices that breach the normal host defences is an important risk factor for nosocomial disease. Prosthetic material also

Experimental Disease Models

It is not unheard of for drugs to be evaluated in the laboratory against certain tumor types and then be found to have activity in different tumors in the clinic.25 Analyses of the correlation between activity in human tumor cell lines in vitro and in vivo to phase II clinical activity demonstrate that some tumor types correlate more positively than others, and that the correlations are also dependent on the drug. Johnson et al. found that only non-small cell lung cancer (NSCLC) xenografts were predictive of clinical activity in the same histology. Breast xenograft models were most useful in predicting activity in NSCLC, melanoma, and ovarian cancer, but not clinical breast cancer.26 The analysis also showed that compounds found to be active in at least one-third of broader panels of xenografts were more likely to show activity in patients in phase II trials although, again, the correlation of specific in vitro cell type to clinical histology was not good. An extension of this...

Gelsolin In Human Diseases

A number of studies have suggested a role for gelsolin as a tumor suppressor gene mainly in breast cancer and carcinomas (Mullauer et al., 1993 Asch et al., 1996 Mielnicki et al., 1999 Onda et al., 1999 Fujita et al., 2001). Gelsolin expression is also downregulated in 60-90 of tumors during carcinogenesis of breast, colon, stomach, bladder, prostate, and lung (Asch et al., 1999 Kuzumaki et al., 1997 Tanaka et al., 1995 Dosaka-Akita et al., 1998 Prasad et al., 1997 Sagawa et al., 2003).

Tregulatory Cell Depletion

Because of the phenotypic similarity between CD4+CD25+ cutaneous T cell leukemia lymphoma cells, for which Ontak is approved for treatment, and CD4+CD25+ Tregs, we hypothesized that Ontak would deplete CD4+CD25+ Tregs in humans. We undertook a clinical trial demonstrating that in blood of human patients with cancer, Ontak depleted functional Tregs, correlating with improved measures of immunity 34 and therapeutic benefit 35 . A clinical trial 36 showed that pretreatment with Ontak improves the immunogenicity of vaccination with RNA-transfected dendritic cells, enhancing the stimulation of tumor-specific T cells in patients with renal cell cancer compared to vaccination alone. This report also demonstrated that Ontak depleted functional Tregs in blood, and the authors speculated that as the mechanism of action. Ontak depletes tumor-associated Tregs and improves immune-mediated rejection of tumor in a mouse model of breast cancer 37 . Nonetheless, a clear link between Treg depletion and...

Biological Function of GAGs A Chondroitin Sulfates

(32), ADAMTS4 (32), and ADAMTS7B (33). MMP-2 is activated by direct binding of chondroitin sulfate to the C-domain of pro-MMP-2, which is essential to present the inactive enzyme to its activator, the membrane type 3 matrix metallo-proteinase (30). Chondroitin sulfate is therefore a key regulator for protein activation and degradation and may explain its involvement in chondrodysplasias (34) and also affects the function of perlecan, though it is yet unclear whether the location of perlecan in the cartilage dictates the link to chondroitin sulfate or vice versa (35). In breast cancer cells, increased numbers of chondroitin sulfate chains linked to P-selectin enhanced the attachment of cancer cells to vascular endothelial cells forcing tissue invasion of tumor cells (36). Increased levels of chondroitin sulfates were also found in melanoma (37) and ovarian carcinoma (38) and enhanced the mitogenic effect of platelet-derived growth factor-BB on fibrosarcoma cells (39). Chondroitin...

Tumor Therapy with Agonist AntiCD137 Antibody

The mechanisms of CD137 mAb-mediated tumor regression are yet to be elucidated. Several possible mechanisms include the breaking of immunological ignorance, prevention of T cell tolerance anergy and deletion, and are largely dependent on the models employed. In an established C3 tumor model, CTLs against a model tumor antigen, human papillomavirus E7 oncoprotein, are not anergic or deleted, but remain naive. Immunological ignorance of specific CTLs appears to prevent anti-CD137 mAb from activating tumor immunity, since anti-CD137 mAb itself neither activates tumor-specific CTLs nor induces the regression of established C3 tumors. Similar observations were made in the TC-1 lung carcinoma and B16-F10 melanoma models. Immunization with E7 tumor peptide in the presence of adjuvant stimulated E7-specific CD8+ CTL, leading to elimination of T cell ignorance, albeit is still insufficient to regress the established C3 tumor. In combination with anti-CD137 mAb, a high level of E7-specific CTLs...

History Of Hematopoietic Stem Cell Transplantation

All mice at a total body irradiation dose of 700 cGy, while unshielded mice all died from marrow aplasia. As the dose of radiation was raised to 1050 cGy, approximately one-third of the shielded mice survived, and a dose of 1200 cGy was lethal to all mice. At autopsy, these latter radiation groups were found to have died from fibrosis of the lungs, liver, and kidneys. The authors erroneously concluded that shielding the spleen was protecting a humoral factor that affected hematopoiesis however, it would subsequently be determined that early hematopoietic progenitors were actually protected from the effects of radiation. From these early studies, theories evolved that radiation and chemotherapy could be administered at controlled, yet highly myelosuppressive doses, which were capable of eliminating malignant hematopoietic clones, and that normal hematopoiesis could be reestablished by the infusion of normal bone marrow. Early animal studies of HSCT were thwarted by incompatibility...

Systemic Associations

Associated immune disorders to be considered in children include rheumatoid arthritis, juvenile-onset diabetes mellitus, asthma, and thyroid disease neoplasia (breast cancer, uterine cancer, carcinoma of the colon, pinealoma) is also seen.408 Thymoma rarely occurs in children although it is recognized to accompany 10 of myasthenia gravis.

Identification of Class II Peptides

HER-2 neu peptides, with the potential for eliciting an immune response, were initially selected using a computer protein sequence analysis package using searching algorithms for identifying motifs according to charge and polarity patterns and tertiary structure, particularly related to amphipathic alpha helices (31). Each of the searching algorithms had empirically been successful in identifying a substantial proportion (5070 ) of Th cell epitopes in foreign proteins (34,35). Analysis resulted in the identification of more than 40 HER-2 neu peptides with a high potential to interact with human class II (1). Based on predicted interactions, 26 peptides, 15-18 amino acids in length, were constructed. Seven of 26 peptides tested demonstrated the ability to elicit T-cell responses, in vitro, in at least some of breast cancer patients evaluated (1). When used in active immunization, four of the seven peptides generated detectable immunity in greater than two-thirds of patients immunized....

Deficiency Signs And Symptoms

Low serum beta-carotene and or low beta-carotene intake has also been associated with a number of clinical conditions, such as type 2 diabetes and poor glycaemic control (Abahusain et al 1999, Coudray et al 1997), non-melanoma and melanoma skin cancer (Gollnick & Siebenwirth 2002), breast cancer (Hacisevki et al 2003), rheumatoid arthritis (Kacsur et al 2002), Alzheimers dementia (Jimenez-Jimenez et al 1999) and age-related macular degeneration (Cooper et al 1999a).

Consolidation of bioenvironment and public health disciplines

Without the etiological background, often, the prevention as well as cure protocols are largely empirical in nature, and therefore, epidemiological undercurrents in observational studies are prominent in this respect. Biomathematical modelings of initiation and growth of cancer may also be quite inadequate in such an empirical setup. Juvenile cancer in the lymph glands and some other areas have a better chance of being cured after proper treatments (that can be painful). In some cases, like the child-leukemia, due to available treatment protocols, the prospect for survival beyond a reasonable length of time is much better at the present time than few decades before. However, in the majority of other cases (including leukemia at a higher age), the major issue may be the survival beyond a small period of time, termed the treatment-period, and even during that time, the quality of life may be a basic concern. Radiation therapy works out for certain organs, but as...

Immunoregulation In The Ocular Surface System

If alterations in local or systemic prolactin expression increase the tendency for activation of DCs and initiation of TH1 effector responses, local expression of TGF- may exert a countervailing influence. It is intriguing to consider that prolactin and TGF- act upon each other in the local signaling milieu. On the one hand, prolactin inhibits expression of TGF- by breast cancer cells (192). On the other hand, TGF- inhibits expression of prolactin by anterior pituitary cells (193), decidualized endometrial cells (194), and GH3 cells (195). As illustrated in Figure 3, immunopositivities for both prolactin immunoreactivity and total TGF- increase markedly within ductal epithelial cells during pregnancy (19). Preliminary results suggest that increases in systemic estrogen and progesterone levels may overcome the mutually inhibitory actions of TGF- and prolactin, since administration of estrogen and progesterone to ovariectomized rabbits appears to elicit the same pattern of changes in...

The inhibitory effects of Avemar on the ribose synthesis pathway supportive of cancer cell proliferation plays an important role in the overall survival rate seen in colon cancer patients. When used in a study of 170 postsurgical colorectal cancer patients also receiving standard of care therapy such as chemotherapy, and or radiation, addition of Avemar reduced new recurrences by 82 , metastases by 67 , and deaths by 62 , compared to use of radiation and chemotherapy alone 26 . It also lengthened the time it took for cancer to become measurably active again after primary therapy (surgery) and adjuvant therapy (chemotherapy and or radiation treatment).

Neuropathophysiology of Pain

Hyperalgesia Stimulus Response Function

Unlike nociceptive pain, neuropathic pain can persist long after the initiating injurious event has been removed and any damage has healed. This then leads to abnormal processing of sensory information by the nervous system. Neuropathic pain can be classified as peripheral (painful peripheral mononeuropathy and polyneuropathy) or central (post stroke, following spinal cord injury) and can originate from nerve injury following a wide array of conditions events, e.g., direct trauma to nerves, inflammation neuritis nerve compression, diabetes, infections (herpes zoster, human immunodeficiency virus (HIV)), tumors (nerve compression infiltration), toxins (chemotherapy), and primary neurological diseases.14'15 Following nerve injury, changes occur in the central nervous system (CNS) that can persist indefinitely. Under these conditions of sensitization, pain can occur without a specific stimulus or can be disproportionate to the stimulus intensity. The sensation of neuropathic pain may...

Arthrotec See diclofenac

Azathioprine (Trade name Imuran) An anticancer drug that interferes with DNA synthesis, particularly in cells regulating the immune system. Azathio-prine is metabolized to active products including 6-mercaptopurine, a related anticancer drug. Smaller doses of azathioprine are used to treat rheumatic diseases other than cancer, and the mode of action is more immunoregulatory as opposed to the cell destruction of cancer chemotherapy. Azathioprine is used as a disease-modifying antirheumatic drug (DMARD) to treat rheumatoid arthritis, usually in patients unable to tolerate other DMARDs. It is also commonly used to treat systemic lupus erythemato-sus, dermatomyositis or polymyositis, vasculitis, and other connective tissue diseases.

Spontaneous resolution in a significant proportion of patients with LCH can occur and patients with a limited disease usually do not require systemic therapy. In contrast, patients with multifocal disease generally benefit from systemic therapy. Treatment options have included low-dose radiation for symptomatic single lesions, local injection of steroids, topical steroids, PUVA, non-steroidal anti-inflammatory drugs, high-dose systemic steroids, and systemic multi-agent chemotherapy regimens with agents such as prednisolone, vinblastine, vincristine, etoposide and 6-mercaptopurine. Other agents, that have been tested in patients with disease progression while on therapy include cyclosporin, antithymocyte globulin, 2-chlorodeoxyadenosine (2CDA), thalidomide, TNF inhibitors, anti-CD1a antibodies and haemopoietic stem cell transplantation.

Therapeutic Drug Monitoring of Antineoplastic Drugs

The platinum derivative cisplatin is used in the treatment of testicular cancer. In most studies determining pharmacokinetic parameters of cisplatin, free fractions were measured in plasma or tumor. There is a high variability between individual patients, and the therapeutic window is narrow. Dosage is often based on body surface area. Recently, Salas et al. (162) described therapeutic drug monitoring of cisplatin using total platinum measurement in plasma. Gietema et al. (163) reported that platinum was detectable in plasma in patients 20 years after being cured from metastatic testicular cancer following cisplatin therapy. Impaired bioavailability of phenytoin in a 24-year-old woman treated with cisplatin, vinblastine, and bleomycin has been reported. Data revealed mean phenytoin absorption of 32 (normal greater than 80 ) establishing malabsorption of phenytoin because of cancer chemotherapy (164). Since the 1960s, 5-fluorouracil has been used either alone or as part of a...

Inflammation of the hip joint Inflammation of the hip

Erosion Femoral Head

AVN may be idiopathic but it is frequently associated with steroid therapy, chemotherapy, liver cirrhosis, and alcoholism. The contour of the femoral head collapses (Fig. 8.56a) and an accelerated osteoarthritis of the hip ensues. MRI detects bone marrow edema associated with femoral head necrosis much earlier than any other method and during a stage when treatment can still be of benefit (Fig. 8.56b), which is why it is indicated in hip pain with no other detectable reason.

Importance Of Psychosocial Factors In Health Maintenance

There is a growing interest in this country in primary prevention as a means to prevent morbidity and mortality and lower health care costs (Woolf, 1999). Evidence-based primary prevention methods such as smoking cessation, exercise, and lowering cholesterol and blood pressure can prevent significantly more deaths than do mainstream tertiary prevention techniques such as the use of ACE inhibitors, b-blockers, aspirin, and warfarin in patients with cardiovascular disease (Woolf, 1999). Primary prevention (e.g., stopping smoking and becoming physically active) is also superior to secondary prevention (e.g., mammography) for decreasing mortality risk in breast cancer (Woolf, 1999). Thus, isolating psychosocial factors that predict the adoption and maintenance of health behavior changes at the earliest time is a major mission of behavioral scientists and organizations such as the National Institutes of Health (NIH). Some psychosocial factors may act as obstacles to practicing positive...

Common Departures For Implementation Of A Protocol 613

1995 Bezwoda (high-dose chemotherapy for metastatic breast cancer) case (Grady, 2000 One of the most notorious examples of outright fraud in clinical trials is the case of Werner Bezwoda, M.D., a South African oncologist. The results of his 1995 paper on high dose chemotherapy for treatment of the patients with metastatic breast cancer published in the Journal of Clinical Oncology were so promising that the U.S. NCI planned large clinical trials based on his results. To assess the integrity of the trial and the quality of the data of the study, the U.S. NCI sent a team to South Africa to conduct an on-site audit for the Bezwoda's study. Despite the resistance and uncorporation from Dr. Bezwoda, the audit team concluded that patient records and diagnoses were unverifiable. Most patients were in fact ineligible, and verifiable data were not sufficient. Consequently, the paper was retracted 6 years after its publication in the Journal of Clinical Oncology.

B6 Collagen Vascular Diseases

Breast cancer patients with CVD should be made aware of the potential for exaggerated acute and late toxicity related to radiation treatment, but should not be considered ineligible for breast conservation with radiation. From three retrospective studies so far, it appears that patients with SCD and other non-RA CVD may be at the highest risk for severe toxicities such that breast radiation in this group should be approached with caution.

Chemokine Receptors and Rheumatoid Arthritis

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation and massive infiltration of leukocytes into the inflamed joints. In RA, a large number of CD4+ memory T-cells infiltrate the inflamed synovium (Kohem, 1996 Morimoto et al., 1988 Morita et al., 1998), where they get activated as they express cytokines and activation makers (Cohen et al., 1995 Dolhain et al., 1996 Grom et al., 1996 MacDonald, 1997 Nanki et al., 2000a,b Smeets et al., 1998). Inflammatory cytokines including IL-1, IL-6, IFN-g, and tumor necrosis factor (TNF)-a and activation markers are known to play central roles in the pathogenesis of RA (Nanki et al., 2000a). Although the development of biological drugs targeting these cytokines has produced promising results in the clinical therapy of RA patients, the design of other drugs that are independent of cytokine's function is needed for the improvement of RA chemotherapy. Previously, Nanki et al. reported that the memory T-cells express...

Sources Of Disease Misclassification

A commonly encountered decision in selecting a disease endpoint is the optimal level of aggregation or disaggregation, sometimes referred to as lumping versus splitting. The decision should be based on the entity that is most plausibly linked to exposure, reflecting an understanding of the pathophysiology of the disease generally and the specific etiologic process that is hypothesized to link exposure to the disease. There are unlimited opportunities for disaggregation, with subdivisions of disease commonly based on severity (e.g., obesity), age at occurrence (e.g., premenopausal versus postmenopausal breast cancer), exact anatomic location (e.g., brain tumors), microscopic characteristics (e.g., histo-logic type of gastric cancer), clinical course (e.g., Alzheimer's disease), molecular traits (e.g., cytogenetic types of leukemia), or prognosis (e.g., aggressiveness of prostate cancer). For any given disease, experts are continually deriving new ways in which the disease might be...

Vascular Endothelium A Possible Therapeutic Target in RA

Therapeutic agents and strategies are being devised to either interrupt or inhibit one or more of the pathogenic steps involved in angiogenesis, and blockade of neovascularization has been effective in many tumor models. Clearly angiogenesis can be targeted at several different stages, including inhibition of production of stimuli such as VEGF, binding of proangiogenic factors (using antibodies or soluble receptors), interruption of downstream signaling, blockade of matrix degradation, or even using antiangio-genic stimuli such as angiostatin or K1-5. Many of these approaches have been used with varying degrees of success for human cancers. The first anti-angiogenic agent, beva-cizumab (Avastin), is an anti-VEGF antibody and was approved in December 2003 by the US Food and Drug Administration (FDA) as first-line treatment of patients with metastatic carcinoma of the colon or rectum in combination with intra-venous 5-fluorouracil-based chemotherapy.
