Background: While age at death is on the rise, the number of postmortem examinations is declining and is disproportionately low among the elderly population. Research on the subject of gender-associated pathology in the elderly is also scarce.

Objective: To seek eventual gender-related differences in autopsies of elderly patients.

Methods: We analyzed the data extracted from a published report on 93 PMEs[1] performed at a geriatric hospital during the past 20 years.

Results: Ninety-three autopsies, representing 1.2% of the 8,101 deaths during these 20 years, were performed. Forty-five of the deceased were women and 48 were men. The incidence of pulmonary embolism was significantly higher in women (28%) than in men (10%) (P< 0.02). There was no significant difference in the gender distribution of the other diagnoses.

Conclusion: Gender distribution of PME-based causes of death in elderly patients revealed a significant rate of pulmonary embolism in women. A thorough search of the medical literature revealed two previous studies with similar findings. Further research will determine whether pulmonary embolism is more frequent or whether it has a worse prognosis in frail elderly women.

Background: Menopause affects women's health and well-being, but their knowledge of proper care and maintenance is uncertain.

Objective: To assess the attitude and approach of the healthy, low risk, postmenopausal population in Israel to personal healthcare and menopause.

Methods: The study population comprised 500 menopausal women attending community outpatient primary care clinics. All women completed a 20-item questionnaire covering personal healthcare habits, lifestyle, knowledge about menopause, and attitude and approach to menopause and use of hormone replacement therapy.

Results: The patients' mean body mass index was 25.8 ± 4.1 kg/m²; more than half the women were overweight, 28% percent engaged in regular sports activity, nd 11.2% smoked; 74% had a positive attitude towards their age; 60% underwent yearly screening mammography; 74% have had Pap smear and 86% had lipid profile measurements during the last year; self-examination of the breast was regularly performed by only 49%. HRT[1] is currently being used by 27% and had been used in the past by another 16%. The primary reasons for stopping therapy were irregular bleeding in 38% and apparent ineffectiveness in 35%. There was a positive significant correlation between level of education and both undergoing regular medical screening and engaging in regular sports activity. HRT current utilization was negatively associated with age and being a housewife.

Conclusions: A relatively high percentage of the study population safeguards its health and regularly uses HRT. We believe that stronger efforts are needed in Israel to promote good healthcare habits and positive attitudes toward menopause and HRT use.

Background: Genes that confer mild or moderate susceptibility to breast cancer may be involved in the pathogenesis of sporadic breast cancer, modifying the phenotypic expression of mutant BRCA1/BRCA2 alleles. An attractive candidate is the insulin-like growth factor I, a known mitogen to mammary ductal cells in vivo and in vitro, whose serum levels were reportedly elevated in breast cancer patients.

Objective: To evaluate the contribution of the IGF-1 gene polymorphism to breast cancer risk by genotyping for a polymorphic allele size in breast cancer patients and controls.

Methods: We analyzed allele size distribution of the polymorphic CA repeat upstream of the IGF-I gene in 412 Israeli Jewish women: 268 women with breast cancer (212-sporadic and 56 carriers of either a BRCA1:or BRCA2 mutation), and 144 controls. Genotyping was accomplished by radioactive polymerase chain reaction of the relevant genomic region and size fractionation on polyacrylamide gels with subsequent auloradiography,

Results: Among women with breast cancer, with or without BRCA germline mutations, 196 and 198 basepair alleles were present in 4.7% (25/536 alleles), compared with 9% (26/288) controls (P = 0.02). This difference was more pronounced and significant in the non-Ashkenazi population. Conversely, the smaller size allele (176 bp) was present in the breast cancer group only {3/536, 0.6%).

Conclusions: The IGF-I polymorphism may serve as a marker for breast cancer risk in the general Jewish population, in particular non-Ashkenazi Jews, but extension and confirmation of these preliminary data are needed.
 

Background: Despite the controversy regarding the risks and benefits of hormone replacement therapy, studies in various countries indicate a two- to threefold increase in the use of HRT[1] during the last decade.

Objectives: To estimate the prevalence of HRT use among post-menopausal Jewish women in Israel and to determine the variables predicting current HRT use.

Methods: A cross-sectional telephone survey was conducted in 1998 on a random sample of Jewish women aged 45–74. Of 935 women who were located and eligible, 704 (75%) were interviewed by means of a structured questionnaire.

Results: A total of 589 women (85%) were peri-menopausal or post-menopausal.  Ninety-nine of them (16.8%) were currently using HRT and 78 (13.2%) were past users. Higher rates of current use were found among women who had undergone hysterectomy and/or oophorectomy (38%) than among all other women (13.5%).  Among naturally menopausal women the highest rate of current use (25.6%) was found in those aged 55–59.  A multiple logistic regression showed that the variables associated with current HRT use among naturally menopausal women  were: having a regular gynecologist (odds ratio 3.6, 95% confidence interval 1.7–7.5), visiting a gynecologist during the past year (OR[2] 2.9, 95% CI[3] 1.4–6.0), experiencing symptoms of menopause (OR 2.0, 95% CI 1.01–3.8), having more than a high-school education (OR 1.9, 95% CI 1.04–3.6), and a lower body mass index (OR 0.91, 95% CI 0.85–0.99).

Conclusions: The factors associated with HRT use may be markers for other socioeconomic or psychological characteristics. The disparities noted between population subgroups may be indicative of differences in awareness or in the delivery of preventive healthcare services to women in Israel, and as such need to be addressed by the health system.

Background: Genetic factors have been shown to play a major role in the development of peak bone mass, with hereditability accounting for about 50-85% of the variance in bone mass. Numerous candidate genes were proposed to be involved in osteoporosis, but the precise genes and their relative contribution remain unknown.

Objectives: To gain insight into the genetic basis of idiopathic low bone mineral density in Israeli patients by analyzing the impact of two candidate genes: polymorphism of the vitamin D receptor gene and polymorphism A986s in the calcium-sensing receptor gene.

Methods: We analyzed 86 Jewish Israeli patients with LBMD[1]: 38 premenopausal women and 48 men, and compared the allelic pattern distribution with that of the general population (126 men and 112 women). Genotyping of the VDR[2] gene was performed in three polymorphic sites using restriction enzymes, and allelic analysis of A986s polymorphism in the CaSR[3] gene was performed using the denaturing gradient gel electrophoresis technique.  

Reaults: In LBMD women the distributions of VDR alleres in Apal polymorphism were AA=7/28, Aa=16/28 and aa=5/28; in TaqI polymorphism TT=10/31, Tt=16/31 and tt=5/31; and in BsmI polymorphism BB=7/32, Bb=14/32 and 11/32. In LBMD men the distributions were AA=17/39, Aa=21/39 and aa=1/39; in TaqI polymorphism TT=12/42, Tt=23/42 and tt=7/42; and in BsmI polymorphism BB=12/41 Bb=18/41 and bb=11/41. The distributions of all these polymorphisms in the control groups were not significantly different. Adjusting for the independent age and gender parameters confirmed that these three polymorphisms of the VDR gene did not have a significant effect on bone mineral density. Thirty percent (24/79) of LBMD patients of either sex displayed heterozygosity of the CaSR A986s polymorphism, compared with 40 of 203 controls (19.7%) (P=0.059). Adjusting for age and gender in these patients revealed a significant difference in the femoral neck BMD[4] between homozygotes and heterozygotes (P=0.002). The age at menarche of the LBMD women was found to predict 61% of the variance of femoral neck BMD.

Conclusions: In Israeli Jewish men and premenopausal women VDR gene alleles do not seem to be associated with lower lumbar spine or femoral neck BMD. A trend towards heterozygosity for a CaSR polymorphism missense mutation was noted in the LBMD patients. Age at menarche in the LBMD women was found to be an important predictor of BMD. A significant difference was found between LBMD women and healthy control women towards heterozygosity for a CaSR polymorphism, as well between homozygotes and heterozygotes for a CaSR polymorphism in BMD. The significance of these findings and their applicability to a larger population awaits further studies.

Background: Domestic violence is a prevalent problem with serious consequences, including a 30% risk of death. The lifetime prevalence ranges from 21 to 34%, with 8–14% of them reporting abuse in the previous year. The incidence seen in primary care practice is about 8%. Despite this high rate, domestic violence is under-diagnosed in primary care.

Objectives: To estimate the prevalence of domestic violence among women visiting a primary care center, to characterize them and to evaluate a screening tool.

Methods: A brief anonymous questionnaire (in Hebrew and Russian) for self-completion was used as a screening tool. During October 1998 we distributed the questionnaires in a primary care clinic in Beer Sheva to all women aged 18–60 years whose health permitted their participation. A woman was considered at high risk for domestic violence when she gave a positive answer to at least one of the three questions related to violence. The risk factors for domestic violence were calculated by odds ratio with 95% confidence intervals.

Results: The response rate was 95.7%. We found 41 women (30.8%) at high risk for violence. Women preferred talking about this issue with their family physician. Women at highest risk were older than 40 years, had emigrated from the former Soviet Union during the last 10 years, were living alone, and were unemployed. None of the women visited the Domestic Violence Center during the study period and 2 months thereafter. Only three women tore off the address and phone number of the center that were attached to the questionnaire.

Conclusions: The anonymous questionnaire was well accepted and had a high compliance rate. Its disadvantages are that respondents must be literate and that it permits the woman to continue with her “secret-keeping” behavior. A high prevalence of domestic violence among women visiting a primary care clinic should convince family physicians to be more active in diagnosing the problem accurately among their patients, providing treatment and preventing further deterioration and possible danger. Further effort should be directed at improving the clinic staff's ability to detect domestic violence among patients, and in developing management programs in the health system to help combat domestic violence.

Background: Which medical specialties do Israeli medical graduates choose? Answers to this question can serve as an essential means of evaluating both Israeli medical education and the healthcare system.

Objectives: To determine the distribution of medical specialty choice, its change over time and the posible influence of the medical school on the choice; to study the graduates’ gender, gender variability in specialty choice of family medicine as a career among the graduates as a group, by medical school, gender, and time trends.

Method: The study population comprised all graduates of the four medical schools in Israel during 16 years: 1980-1995 inclusive. Data were obtained from the four medical schools, the Israel Medical Association’s Scientific Council, and the Ministry of Health. Data allowed for correct identification of two-third of the graduates.

Results: A total of 4,578 physicians graduated during this period. There was a significant growth trend in the proportion of women graduates from 22.6% in 1980 (lowest: 20.0% un 1981) to 35.3 in 1995 (highest: 41.5% in 1991). Overall, 3,063 physicians (66.8%) started residency and 1,714 (37.4%) became specialists. The four most popular residencies were internal medicine. Ten percent of Israeli graduates choose family medicine.

Conclusions: The overall class size in Israel was stable at a time considerable population change. Women’s place in Israeli medicine is undergoing significant change. Family medicine is one of the four most popular residencies. Amonitoring system for MSC in Israel is imperative.
 

Background: Many women stop smoking before or during pregnancy, or while breast-feeding (nursing).

Objectives: To assess the relation between breast-feeding and smoking habits.

Methods: A survey was conducted among 920 women attending family health clinics (group 1) and a maternity department (group 2) on their breast-feeding and smoking habits.

Results: A total of 156 women (16.95%) smoked during pregnancy. A significant correlation was found between breast-feeding and not smoking after delivery (P=0.009 in group 1, P=0.03 in group 2). A higher tendency to nurse was found among women with an uneventful pregnancy, who vaginally delivered a singleton at term weighing 2,500-4000 g, and who received guidance on breast-feeding.

Conclusion: Professional guidance in favor of breast­feeding is crucial to increase the rate of nursing. Encouraging breast-feeding will probably decrease the rate of cigarette smoking.
 

Background: Urinary incontinence in older women is common. Its characteristics and impact on quality of life is not well established since these women are usually reluctant to tell their healthcare providers about the problem.

Objective: To determine the characteristics of urinary incontinence in women and the manner in which it affects patients quality of life.

Methods: Twenty family physicians were requested to distribute a questionnaire to the first 25 consecutive women aged 30 to 75 years who visited their clinic for any reason. The questionnaire covered general health issues, symptoms of urinary incontinence, and quality of life.

Results: A total of 418 women, mean age 50.0 ± 11.8 years, completed the questionnaire (84% response rate). Of these, 148 (36%) reported having episodes of urinary incontinence. Urinary incontinence was found to be associated with older age, menopause, obesity and coexisting chronic disorders. Sixty percent of the women with urinary incon­tinence found it to be a disturbing symptom, and 44% reported that it had a detrimental effect on their quality of life. Only 32% of the affected women had sought medical advice, half of them from their family physician. Treatment was recommended to 66% of those who sought help, and in about two-thirds of these it brought some measure of relief.

Conclusions: Urinary incontinence is a common com­plaint among women attending primary care clinics, but it does not receive appropriate attention, Though it often adversely affects quality of life, only a small proportion of women seek medical advice. Family physicians should raise the issue as a part of the routine general health check-up.
 

Background: Information is lacking on the effects of hormone replacement therapy in women with diabetes, especially during moderate chronic hyperglycemia.

Objectives: To study the effects of HRT on the lipid profile and the low density lipoprotein subclass distribution in women with type 2 diabetes under satisfactory and non-satisfactory glycemic control.

Methods: Fifty-four postmenopausal women after a 6 week run-in diet were randomized to receive either placebo(HbAlc <8%, n=13 HbAlc >8%, n=17) or HRT (HbAlc<8%, n=11 HbAlc >8%, n=13) for 12 weeks. HRT consisted of cyclical conjugated estrogens 0.625 mg/day plus medrogestone 5 mg/day. At the beginning and at the end of each treatment period the LDL subclass distribution was estimated by density gradient ultracentrifugation.

Results: At the baseline and during the study, the HbAlc level was significantly higher in hyperglycemic patients than in the near-normoglycemic controls (baseline 10.2±2.9 vs. 6.5±0.7%, P<0.01). They showed a trend for higher total and LDL cholesterol, triglycerides and lower high density lipoprotein-cholesterol compared to near-normoglycemic con­trols, as well as significantly higher triglyceride concentrations in very low density lipoprotein, intermediate density lipoprotein and LDL-1 particles and cholesterol content in LDL-1 and -2 particles. HRT decreased LDL-cholesterol in both groups. In the normoglycemic patients a small increase in HbAlc was observed (6.5±0.7 vs. 7.4+1%, P=004). In all cases, HRT did not modify the proportion of LDL represented by denser LDLs.

Conclusions: HRT did not modify the LDL subclass distribution, even in the presence of moderate chronic hyperglycemia in women with type 2 diabetes.

Background: *Previous descriptive studies have demonstrated the problematic nature of physicians' attitudes toward battered women. However, little empirical research has been done in the field, especially among the various medical specialties.

Objectives: To compare the approach and feelings of competence regarding the care of battered women between primary care and non-primary care physicians. The non-primary care physicians who are likely to encounter battered women in the ambulatory setting are gynecologists and orthopedists.

Methods: A self-report questionnaire formulated for this study was mailed to a random sample of 400 physicians working in ambulatory clinics of the two main health maintenance organizations in Israel (300 primary care physicians, 50 gynecologists and 50 orthopedists).

Results: In both physician groups, treating battered women tended to evoke more negative emotional states than treating patients with infectious disease. The most prevalent mood state related to the management of battered women was anger at her situation. Primary care physicians experienced more states of tension and confusion than non-primary care physicians and had lower perceived self-efficacy and self-competence in dealing with battered women.

Conclusions: Though both physician groups exhibited negative feelings when confronting battered women, the stronger emotion of the primary care physicians may indicate greater sensitivity and personal awareness. We believe that more in-service training should be introduced to help physicians at the undergraduate and postgraduate levels to cope both emotionally and professionally with these patients.

Background: A high rate of consanguineous marriages exists within the Israeli Arab community, with approximately half occurring between first cousins. This contributes towards a high incidence of congenital malformations and autosomal recessive diseases, many of which are detectable at prenatal diagnosis.

Objectives: To assess the levels of both awareness and acceptance regarding prenatal diagnosis and termination of pregnancy among a group of Arab women in order to devise the optimal means of providing genetic counseling and general health services.

Methods: A total of 231 Arab women of childbearing age were interviewed 3 days postpartum to assess their knowledge of prenatal diagnosis and termination of pregnancy, their willingness to undergo prenatal diagnosis, and their opinions on termination of pregnancy in the event of a severely affected fetus.

Results: Half the women believed that prenatal testing is not an effective (or accurate) tool for diagnosing an affected fetus. A quarter had poor knowledge on prenatal diagnosis, and a quarter believed that prenatal diagnosis does provide the correct diagnosis. Ninety-five percent said they would agree to undergo prenatal diagnosis; and in the event of a severely affected fetus, 36% said they would agree to a termination of pregnancy, 57% said they would not, and 7% were undecided.

Conclusions: There is a need for special intervention programs, with guidance by health professionals, geneticists and religious authorities, that will inform this population on the increased risk associated with consanguinity, stress the importance and effectiveness of prenatal testing to identify severe congenital malformations, and help them to accept prenatal diagnosis and termination of pregnancy if indicated.

Background: The preconception and intraconception parameters that are relevant to outcome in women with underlying renal disease remain controversial.  

Objectives: To analyze the types and frequencies of short- and long-term (2 years after delivery) maternal and neonatal complications in 38 patients with primary renal disease (46 pregnancies), most of them with mild renal insufficiency.  

Methods: Logistic regression models were formulated to predict successful outcome.  

Results: Successful pregnancy outcome (live, healthy infant without severe handicap 2 years after delivery) was observed in 98% of the patients with primary renal disease. Factors found to be significantly predictive of successful outcome were absence of pre-existing hypertension, in addition to low preconception serum uric acid level.

Conclusions: Most women with primary renal disease who receive proper prenatal care have a successful pregnancy outcome. Worse pregnancy outcome was observed in women with moderate or severe renal failure. Fitted logistic models may provide useful guidelines for counseling women with preexisting renal disease about their prospects for a successful pregnancy in terms of immediate and long-term maternal and neonatal outcome.
