Endometriosis is a chronic disease characterized by ectopic deposits of endometrial glands and stroma located outside the uterus. Women with symptomatic endometriosis may experience premenstrual bleeding or staining, pain and other physical sensations, as well as other symptoms dependent upon the stage and location of the endometrial implants. We discuss the particular implications of these symptoms for women who observe the part of Jewish law known as hilkhot niddah. The laws of niddah, also known as taharat hamishpahah (family purity), dictate the timing of the physical relationship between a married couple. These laws proscribe any physical contact between the couple during the time that the wife has the status of niddah. This status is obtained by any uterine bleeding that is not caused by injury. Menstruation is the most common cause of the niddah status, but niddah and menstruation are not synonymous. Since, to the best of our knowledge, there is no written discussion of the specific implications of endometriosis for this population, we discuss the relevant halakhic and medical literature and hope that such analysis will facilitate efforts to assist the observant couple in gaining regular niddah-free segments of time.

Background: Along with the increased life expectancy in cystic fibrosis and the remarkable progress in its management and therapy, issues of female fertility and pregnancy are frequently raised. These include infertility, severity of lung disease, pancreatic insufficiency, poor nutritional status, glucose intolerance and diabetes, drug safety, and long-term maternal and neonatal outcome.

Objective: To describe the experience of our CF[1] center in the management of CF pregnant woman from 1977 to 2004.

Methods: We analyzed 27 years of records (1977–2004) of the national CF registry of all CF women who wished to conceive and became pregnant.

Results: Eight CF women (mean age 24 ± 4.5 years) who wished to conceive had 11 pregnancies and delivered 12 neonates. The pregestational results of forced expiratory volume per 1 second varied significantly among patients (59 ± 23%), yet most (10/11) stayed stable throughout the pregnancy course. Maternal deterioration in CF condition occurred in only one mother, necessitating cesarean section. In 9 of the 11 pregnancies the women were pancreatic-insufficient. Of the 11 pregnancies, 2 CF women had diabetes mellitus and 3 developed gestational diabetes. One pregnancy occurred in a mother with a transplanted lung. Of the 12 neonates, 3 were preterm and one was born with esophageal atresia. No miscarriages, terminations or neonatal mortalities occurred. Although most of the CF mothers had FEV1[2] below 55% before pregnancy, the maternal and neonatal outcome was favorable and lung function tests generally remained stable.

Conclusions: We conclude that pregnancy in CF is feasible with a positive maternal and neonatal outcome. Early participation of the CF physician in the wish of the CF woman to reproduce is required. The integration of an intensive multidisciplinary approach during pregnancy, which includes close follow-up of maternal and fetal condition by the various specialists, should ensure an optimal outcome.

Background: Until recently trimethoprim-sulfamethoxazole was the drug recommended in the Leumit Health Fund for the empiric treatment of uncomplicated urinary tract infection in women. However, due to increased uropathogen resistance to this drug, the fund has designated nitrofurantoin as its new drug of choice.

Objectives: To evaluate the potential economic impact of implementing this new pharmaco-policy.

Methods: Using data derived from the electronic patient records of the Leumit Health Fund we identified all non-recurrent cases of women aged 18–49 with a diagnosis of acute cystitis or UTI[1] without risk factors for complicated UTI and empirically treated with antibiotics throughout 2003. The final sample comprised 5,489 physician-patient encounters. The proportion of cases treated with each individual drug was calculated, and the excess expenditure due to non-adherence to the new guideline from the perspective of the health fund was evaluated using 5 days of therapy with nitrofurantoin as the reference treatment.

Results: Ofloxacin was the most frequently prescribed drug (30.24%), followed by TMP-SMX[2] (22.43%), cephalexin (15.08%), and nitrofurantoin (12.59%). The observed net aggregate drug expenditure was 2.3 times greater than expected had all cases been treated with nitrofurantoin according to the guideline duration of 5 days. The cost of treatment in 53% of the cases exceeded the expected cost of the guideline therapy.

Conclusions: Successful implementation of the new drug policy will likely improve quality of care and reduce costs to the health fund.

Background: Oral contraceptive users are at increased risk for both arterial and venous thrombosis, some of which can be fatal. Studies are consistent with the existence of a synergism between cigarette smoking and OC[1] use in the pathogenesis of myocardial infarction in young women.

Objectives: To study the relationship between OC use, cigarette smoking and other cardiovascular risk factors among young women.

Methods: A systematic sample of military personnel, upon discharge from service in the Israel Defense Forces, was asked to complete a research questionnaire. Body weight and height were measured and body mass index computed.

Results: Overall, 16,258 questionnaires were collected and analyzed during this 20 year study. There was a gradual, significant increase in OC use until the mid-1980s, from approximately 45% to 60% (P < 0.001), followed by steady rates of 58–64% since then. In contrast, the rates of smoking decreased significantly in the mid-1980s, from approximately 42% to a nadir of 22% in 1991. Since then, the rate of smoking has increased slowly but steadily, to reach a level of 35% in 1999. The OC users were more often of western (Ashkenazi) origin and came from families with more education and fewer siblings. They were more often smokers than non-OC users, and started smoking at a younger age. They had significantly lower BMI[2] than non-users. OC use was nearly identical in groups with or without multiple cardiovascular risk factors (smoking, obesity, family history).

Conclusions: Smoking and OC use are strongly associated. Other cardiovascular risk factors (smoking, obesity, family history) do not prevent OC users from smoking or smokers to use OC. We suggest that primary care physicians discourage smoking among adolescent females who wish to start using OC. A thorough medical history should be obtained to recognize all risk factors for cardiovascular disease and to provide for appropriate contraception counseling.

Background: In Israel, preventive services for mothers and children are provided mainly by the Ministry of Health through a network of Maternal and Child Health clinics, and partly by municipalities and health maintenance organizations. Utilization of the MCH[1] clinics for prenatal care has declined during the last decades.

Objective: To study the utilization and satisfaction with prenatal care services following the introduction of the National Health Insurance Law.

Methods: The study population comprised a national sample of Jewish and Arab women who were interviewed by telephone regarding the following: main service utilized for prenatal care, physician and nursing visits, satisfaction with care, and demographic and other characteristics. The response rate was 92% among Jewish women and 88% among Arab women.

Results: Twenty percent of the Jewish and 52% of the Arab women selected MCH clinics as the main service for prenatal care. The great majority of the study population attended the HMO[2] services (clinics, independent physicians, women’s health centers), while 7% of the Jewish and 4% of the Arab women visited a private clinic. The predisposing factors affecting the women's choice were educational level, ethnic group, religiosity, district of residence, and type of HMO. The mean number of physician visits was more than the eight visits recommended. Forty percent of the sample visited with three or more physicians at different services. More than 50% of the women had no appointment with a nurse, mainly those who chose the services of an HMO clinic, independent physician, or private physician. Satisfaction with the physician, nurse, and physical structure of the main service chosen for prenatal care was high.

Conclusions: Since the majority of women preferred the HMO services, the merging of prenatal care with curative care provided by the HMOs has to be considered. Public health nurses should be integrated in the service, and their specific role needs to be defined.

Background: Prior studies have suggested that women are at higher risk for morbidity and mortality during coronary angioplasty, although long-term prognosis is similar after successful procedures.

Objectives: To examine the role of gender in coronary stenting, including immediate procedural success as well as early and late outcomes.

Methods: The study group comprised 560 consecutive patients (119 women and 441 men) who had undergone stenting over a 3 year period.

Results: The indications for coronary stenting were similar among women and men, and stents were successfully deployed at similar rates without complications (92 vs. 90% respectively). Cardiac death or myocardial infarction within 30 days of the procedure was observed in 5% of women and men, whereas none of the women, compared to 1.4% of men, had early revascularization. Bleeding complications occurred in 4% of women and 2% of men. During 10 ± 2.8 months of follow-up, 58% of women and men underwent repeat cardiac catheterization, revealing similar rates of restenosis, 36 vs. 32% respectively. During the study period, 3.3% of women as compared to 0.9% of men had a cardiac death (not significant). Cardiac death or myocardial infarction was observed in 7% of women and 8% of men, and the combined endpoint of death, myocardial infarction or revascularization, was noted in 24% and 26% respectively. Multivariate Cox analyses of the clinical, angiographic and procedural characteristics revealed that multiple stent deployment was the only predictor of major adverse cardiac event among men, whereas none of these characteristics predicted outcome in women.

Conclusion: Coronary stenting is performed with similar success rates among women and men, with similar restenosis rates, as well as early and late major adverse cardiac events.

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.
