Abstract
This study examines whether a change in the criteria for genetic testing for ovarian cancer risk changed the nature of referrals into our Familial Cancer service. This is a retrospective review of 273 women who underwent risk reducing surgery (RRS). The primary outcome was to establish whether there was an increase in women having RRS with a confirmed genetic mutation. Secondary outcomes included the incidence of occult cancer and of subsequent primary peritoneal cancer. The results showed an increase in women being offered RRS based on genetic diagnosis; 91% versus 32% before the criteria change. Four occult malignancies (1.5%) and two peritoneal cancers (0.7%) were noted.We have demonstrated a change in the nature of referrals to the familial cancer service from perceived risk to genetic diagnosis. We can now counsel women more accurately. With a defined risk we are enabling them to make an informed decision regarding risk reduction.

Abstract
METHODS We examined monocyte prostaglandin synthase 2 (PGS2/COX2) expression in individuals at risk for or with type 1 diabetes including: (i) 58 established type 1 and 2 diabetic patients; (ii) 34 autoantibody positive (AA+) children and adults; (iii) 164 infants and young children with insulin-dependent diabetes mellitus (IDDM) susceptibility human leukocyte antigen (HLA) alleles; and (iv) 37 healthy control individuals, over a 5-yr period. RESULTS Established type 1 diabetic patients (1 month to 30+ yr post-disease onset) had significantly higher PGS2 expression than healthy controls; by contrast, insulin-treated type 2 diabetic patients had significantly lower PGS2 expression than healthy controls. Longitudinal studies of AA+ subjects at risk for type 1 diabetes indicated that 73% (11/15) of individuals who developed this disease during the study period expressed high levels of PGS2 prior to or after onset. We also found high level PGS2 expression in genetically at-risk infants and young children that correlated with having a first-degree relative with type 1 diabetes, but not with age, gender, or HLA genotype. In this population, high level PGS2 expression coincided with or preceded autoantibody detection in 30% (3/10) of subjects. CONCLUSIONS These findings suggest that high level monocyte PGS2 expression, although subject to fluctuation, is present in at-risk subjects at an early age and is maintained during progression to and after type 1 diabetes onset.

Abstract
BACKGROUND Benzydamine was evaluated in patients with head and neck carcinoma for treatment of radiation-induced oral mucositis, a frequent complication of radiation therapy (RT) for which there is no predictable therapy or preventive treatment currently available. METHODS The safety and efficacy of 0.15% benzydamine oral rinse in preventing or decreasing erythema, ulceration, and pain associated with oral mucositis during RT were evaluated in a randomized, placebo-controlled trial conducted in patients with head and neck carcinoma. Subjects were to rinse with 15 mL for 2 minutes, 4-8 times daily before and during RT, and for 2 weeks after completion of RT; study evaluations were conducted before RT and routinely thereafter up to 3 weeks after RT. RESULTS During conventional RT, regimens up to cumulative doses of 5000 centigrays (cGy) benzydamine (n = 69) significantly (P = 0.006) reduced erythema and ulceration by approximately 30% compared with the placebo (n = 76); greater than 33% of benzydamine subjects remained ulcer free compared with 18% of placebo subjects (P = 0.037), and benzydamine significantly delayed the use of systemic analgesics compared with placebo (P < 0.05). Benzydamine was not effective in subjects (n = 20) receiving accelerated RT doses (> or = 220 cGy/day). The incidence of adverse events between treatment groups was comparable without significant differences. Early discontinuation because of adverse events occurred in 6% of benzydamine subjects and 5% of placebo subjects, and there was 1 death (related to the primary diagnosis) in a placebo subject. CONCLUSIONS Benzydamine oral rinse was effective, safe, and well tolerated for prophylactic treatment of radiation-induced oral mucositis.

Abstract
INTRODUCTION Mondana Clinic is a small rural clinic located in the Napo river region of the Amazon basin in Ecuador. Since its opening in 1997 the clinic has grown to be the primary health care facility for approximately 3000 individuals. METHODS A retrospective study was performed tabulating the ambulatory diagnosis, age, sex, and domicile of patients over a 9 month period in 1999. RESULTS During the study period there were 765 patient visits that resulted in at least one diagnosis. Of the patient visits, 175 (22.8%) resulted in multiple diagnoses. Women accounted for 58% of the patient visits, which is similar to the 60% of ambulatory patient visits made in the USA by women. The age distribution showed 66% of patients were under 25 years of age. When comparing diagnoses of males with females, several differences were noted. As expected, urinary tract infections were approximately four-fold more common in females than in males. Gastritis and headaches were also more common reasons for patient visits in the female population than in the male. Conversely, lacerations, abrasions, and contusions ranked higher in the male than in the female population for patient visits. CONCLUSION This study is the first to provide public health information for this region that will prove useful to the health professionals and funding agencies working in the region. Furthermore, it provides a baseline for comparison with other regions in Ecuador and South America in general, as well as comparisons with data-rich countries such as the USA.

Abstract
We report here our prospective study of 15,224 non-diabetic, first-degree relatives of probands with immune-mediated (type 1) diabetes (IMD), of which 135 were found to eventually develop diabetes. We determined islet cell, insulin, GAD65, insulinoma-associated antigen-2 and 2beta autoantibodies (ICA, IAA, GAD65A, IA-2A and IA-2betaA), on the first available serum samples. The latter three autoantibodies were however assayed on subsets of the relatives with and without ICA, IAA and/or GAD65A, plus most of the relatives who developed diabetes. Of the relatives who progressed to diabetes, 94% had at least one of these autoantibodies on the first screening, while ICA proved to be the most sensitive single marker (sensitivity 74%). Risk of diabetes was however negligible when ICA was found in the absence of the others (5-year risk=5.3%), but increased dramatically whenever two or more autoantibodies were present (5-year risk=28.2% and 66.2%, respectively). The most predictive combination of markers was ICA plus IA-2A and/or IA-2beta A. Loss of first phase insulin release to IVGTT also occurred only in those ICA-positive relatives who had one or more of the other autoantibodies. The data suggests that significant beta-cell damage is seen only when the underlying autoimmunity has spread to multiple antigenic islet cell determinants. Combinations of the autoantibodies occurred most often in relatives with the highest risk HLA-DR/DQ phenotypes. These data document that only relatives positive for at least two or more of these five autoantibodies are at significant risk of diabetes themselves. Intervention trials for the prevention of type 1 diabetes could be designed based on testing for these autoantibodies alone, without the need for HLA typing and IVGTT testing.

Abstract
Female transgenic mice lacking a functional c-mos proto-oncogene develop ovarian teratomas, indicating that c-mos may behave as a tumour-suppressor gene for this type of tumour. We have analysed the entire coding region of the c-MOS gene in a series of human ovarian teratomas to determine whether there are any cancer-causing alterations. DNA from twenty teratomas was analysed by single-strand conformational analysis (SSCA) and heteroduplex analysis (HA) to screen for somatic and germline mutations. In nine of these tumours the entire gene was also sequenced. A previously reported polymorphism and a single new sequence variant were identified, neither of which we would predict to be disease-causing alterations. These results suggest that mutations in the coding region of the c-MOS gene do not play a significant role in the genesis of human ovarian teratomas.

Although DR3-DQB1*0201 may be associated with multiple component diseases of the autoimmune polyglandular syndromes, the human leukocyte antigen DR4-DQB1*0302 haplotype is implicated only in beta-cell autoimmunity.

Abstract
Human leukocyte antigen (HLA)-DRB1 and -DQB1 alleles were analyzed using a PCR-based sequence-specific priming technique in 16 patients with autoimmune polyglandular syndrome type I (APS-I), 31 patients with APS-II, and 110 patients with component diseases of APS-II, including 9 patients with isolated Addison's disease, 43 patients with Hashimoto's thyroiditis, 22 patients with Graves' disease, and 36 patients with vitiligo. No significant associations was observed between HLA and APS-I patients in our data set, nor was sharing of HLA haplotypes by sibling pairs affected by APS I significantly different from the random expectation. Thus, HLA-DRB1 and -DQB1 genes are probably not involved in APS-I. To delineate the associations between HLA-DRB1, DQB1, and APS-II, we analyzed APS-II patients with or without beta-cell autoimmunity [i.e. insulin-dependent diabetes (IDD) and/or islet cell or glutamic acid decarboxylase autoantibodies]. Our results suggest that the association between DR4-DQB1*0302 and APS-II was entirely due to the presence of pancreatic beta-cell autoimmunity, since this haplotype was otherwise not significantly associated with APS-II or with any other of its component diseases. In contrast, the DR3-DQB1*0201 haplotype was associated not only with IDD, but also with APS-II in the absence of pancreatic beta-cell autoimmunity, as were several its component diseases, including isolated Addison's disease, Graves' disease, and Hashimoto's thyroiditis. Interestingly, the frequency of DQB1*0602, a dominantly protective allele against IDD, was not significantly decreased in the APS-II patients with IDD or beta-cell autoimmunity, albeit the patient numbers were small. This phenomenon may suggest that the development of autoimmunity to nonpancreatic endocrine glands may predispose autoimmunity to the pancreatic beta-cells and involve genes other than those of the MHC.

Abstract
This study compares the efficacy of a school-based program to an equivalent home-based program with 2,250 third grade students in 31 urban schools in Minnesota in order to detect changes in dietary fat and sodium consumption. The school-based program, Hearty Heart and Friends, involved 15 sessions over five weeks in the third grade classrooms. The home-based program, the Home Team, involved a five-week correspondence course with the third graders, where parental involvement was necessary in order to complete the activities. Outcome measures included anthropometric, psychosocial and behavioral assessments at school, and dietary recall, food shelf inventories, and urinary sodium data collected in the students' homes. Participation rates for all aspects of the study were notably high. Eighty-six per cent of the parents participated in the Home Team and 71 per cent (nearly 1,000 families) completed the five-week course. Students in the school-based program had gained more knowledge at posttest than students in the home-based program or controls. Students in the home-based program, however, reported more behavior change, had reduced the total fat, saturated fat, and monounsaturated fat in their diets, and had more of the encouraged foods on their food shelves. The data converge to suggest the feasibility and importance of parental involvement for health behavior changes with children of this age.

Abstract
This exploratory study investigated perceptions of palliative home care nurses regarding their roles. Results are based on structured interviews with all ten nurses providing care in a home care program for dying patients. Most nurses agree that nursing the terminally ill is a distinctive kind of nursing, requiring particular capabilities, and providing its own unique frustrations and satisfactions. While nurses experienced stress, especially the nurses who had spent a shorter period of time working for the program, they had a variety of ways to cope with stress. Suggestions for hospice program planning and future research are presented.

Abstract
The effect upon the retina of exposure to large fields of bright visible light has been evaluated. The thresholds for permanent retinal damage for four hour exposures in rhesus monkeys have been established for white light, and laser lines of 514.5 nm, 488 nm, 457.9 nm, and 590 nm. The damage has been evaluated by ophthalmoscopy, electroretinography and light and electron microscopy. The shortest wavelength light (457.9 nm) is more effective in causing damage, particularly histological damage, which is spread throughout the fundus and throughout the retinal layers. Functional damage shown by the electroretinogram follows a different action spectrum without the increased effect in the blue. There appears to be more than one mechanism for retinal damage in chronic light exposure, and at least one mechanism is not dependent solely upon the visual pigment and the pigment epithelium. Thresholds of permanent damage appear to be within one or two log units of light levels encountered in the normal visual environment. Newer data suggest that this damage is additive. Daily one hour exposures for four days produce damage equivalent to a single four hour exposure at the same retinal irradiance.
