Objective: To investigate hemodynamic variables, including small and large artery compliance, in cirrhotic patients during total paracentesis.

Methods: The study included 15 cirrhotic patients admitted for an episode of tense diuretic-resistant ascites. Hemodynamic variables including vascular compliance were measured using an HDI pulse wave cardiovascular profiling instrument CR-2000. The variables were measured in these patients before, immediately after and 24 hours following large volume (mean 5.6 L) paracentesis.

Results: Cardiac output increased immediately after paracentesis due to increment in stroke volume, with no change in heart rate. However, 24 hours later the cardiac output decreased to below the basal level. The fluctuation was statistically significant (P < 0.05). There was no change in large artery compliance, but small artery compliance increased after paracentesis (P < 0.05) and partially returned to the basal level after 24 hours. Systemic vascular resistance measurement showed the same pattern of change: vasodilatation occurred during paracentesis and was attenuated 24 hours later.

Conclusions: Large volume paracentesis with albumin replacement caused an accentuation of the vasodilatation (small but not large artery) already present in these patients. This may be the first sign of enhanced vasodilatation due to large volume paracentesis before the clinical expression of impaired hemodynamics and deterioration of renal function.

Objectives: To define the incidence of congenital CMV infection in two different subpopulations, as a model for the entire population of Israel.

Methods: Urine specimens were randomly collected from 2,000 newborns in Shaare Zedek Medical Center, Jerusalem, and HaEmek Medical Center, Afula (1,000 specimens each). These hospitals have many characteristic differences, presumably representing the diverse population of Israel. Urine specimens were subjected to a CMV PCR[2] reaction and positive specimens were validated by urine viral culture. Maternal seroprevalence was determined in a representative sample of the mothers in each hospital. Epidemiologic characteristics of the mothers were extracted from hospital records and compared.

Results: The population in Shaare Zedek Medical Center was mostly Jewish (95.8%) and urban (87.0%), as compared to that of HaEmek Medical Center (49.2% and 61.0%, respectively, P < 0.01). Nevertheless, CMV seroprevalence was similar: 81.5% and 85%, respectively. Ten (1.0%) and 4 (0.4%) newborns, respectively, were found to have congenital CMV infection (not significant).

Conclusions: The combined incidence of congenital CMV infection in the study population was 0.7% (95% confidence interval 0.3–1.0%). If this rate is extrapolated to the entire population of Israel, then a total of 945 cases of congenital CMV can be expected among the 135,000 annual deliveries. A nationwide screening program for congenital CMV should be considered.

Objectives: To describe and analyze how PCPs[1] in the IDF[2] view their roles as primary care providers and to characterize how they perceive the quality of the medical care that they provide.

Methods: We conducted a survey using a questionnaire that was mailed or faxed to a representative sample of PCPs. The questionnaire included demographic background, professional background, statements on self-perception issues, and ranking of roles as a PCP in the IDF.

Results: Statements concerning commitment to the patient were ranked higher than statements concerning commitment to the military organization. Most physicians perceive the quality of the medical care service that they provide as high; they also stated that they do not receive adequate continuous medical education.

Conclusions: Our survey shows that PCPs in the IDF, like civilian family physicians, perceive their primary obligation as serving the needs of their patients but are yet to take on the full role of “gatekeepers” in the IDF’s healthcare system. We conclude that the Medical Corps should implement appropriate steps to ensure that PCPs are prepared to take on a more prominent role as “gatekeepers” and providers of high quality primary medical care.

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: Repaglinide, a new insulin secretagogue, is purported to be as effective as sulphonylurea but is less hypoglycemic-prone.

Objectives: To assess the efficacy of repaglinide and its proclivity for hypoglycemia in a post-marketing study.

Methods: The study group comprised 688 patients, aged 26–95 years, clinically diagnosed with non-insulin-dependent type 2 diabetes. The patients were divided into three groups based on previous therapy: a) sulphonylurea-treated (group 1, n=132); b) metformin with or without sulphonylurea where sulphonylurea was replaced with repaglinide. (group 2, n=302); and c) lifestyle modification alone (drug-naïve) (group 3, n=254). At initiation of the study, all patients were transferred from their current treatment to repaglinide. Only patients in group 2, with combined sulphonylurea plus metformin, continued with metformin plus repaglinide. Fasting blood sugar, hemoglobin A1c and weight were measured at study entry and 4–8 weeks following repaglinide therapy. A questionnaire documented the number of meals daily and the presence of eating from fear of hypoglycemia.

Results: The fasting blood sugar level of the entire cohort dropped from 191 ± 2.4 to 155 ± 2.0 mg/dl (P < 0.0001); HbA1c from 8.8 ± 0.1 to 7.7 ± 0.1% (P < 0.0001). The drop of HbA1c in groups 1, 2 and 3 respectively were: 1.04 ± 0.22% (P < 0.0001), 1.14 ± 0.24% (P < 0.0001), and 1.51 ± 0.31% (P = 0.0137). Weight dropped from 81 ± 0.7 to 80.2 ± 0.7 kg (P < 0.0001), and eating from fear of hypoglycemia from 157 to 97 (P < 0.001). The daily number of meals decreased from 2.9 ± 0.4 to 2.4 ± 0.4 (P < 0.001). No serious adverse reactions occurred during the study.

Conclusions: Repaglinide is an effective oral hypoglycemic agent taken either as monotherapy or combination therapy. There is less eating to avoid hypoglycemia, fewer meals consumed, and weight loss.
 

Objectives: To evaluate operative procedures, complications, early and late results and long-term functional outcome in FAP[1] patients operated in our department.

Methods: The study group included all patients with FAP who were operated between 1988 and 2003. Demographic data, length of follow‑up, complications, colorectal cancer, pouch function and extracolonic manifestations were recorded.

Results: Median age at surgery was 33 years (range 13–61 years). The final operative breakdown was: 48 proctocolectomies, 41 ileal pouch-anal anastomoses, 2 Kock’s pouch, 5 permanent ileostomies, and 2 colectomies with ileorectal anastomosis. There was no perioperative mortality. Early and late complications occurred in 20 and 9 patients, respectively. Twelve patients required re‑operation. Colorectal carcinoma was diagnosed in eight patients, three of whom were in an advanced stage. The mean follow‑up was 74 months (range 3–288 months). Four patients were lost to follow‑up. Extracolonic manifestations developed in 38 patients, including desmoid tumors (in 12), duodenal adenomas (in 9), pouch adenomas (in 5), and rectal stump adenomas (in 3). Two patients died (4%) because of desmoid tumor and malignant fibrous histiocytoma. At last follow‑up, 37 IPAA[2] patients have (median) six bowel movements/24 hours and good fecal control.

Conclusions: Restorative proctocolectomy can be performed with low mortality, acceptable morbidity, and good functional results. Patients should be closely followed after surgery for development of other manifestations of the syndrome. Relatives of the affected patients should be referred to a specialist multidisciplinary clinic.
