Background: Domestic violence is considered a major risk factor in pregnancy.

Objectives: To assess the prevalence of different kinds of abuse (physical, psychological, sexual) of pregnant as compared to non-pregnant women, and to identify demographic risk factors for physical abuse that characterize the woman and her partner.

Methods: A cross-sectional survey was conducted in 270 women seeking gynecologic care at women health centers in northern Israel. Information was collected by means of a standardized questionnaire administered via phone, and addressed demographic data, interaction with the partner, and reporting of physical abuse. All information was obtained from the respondents (including information about her partner).

Results: Four abuse scores were computed: severe physical attack, minor physical attack, psychological abuse, and sexual coercion. Psychological abuse was found to be the most prevalent (24%), followed by minor and severe physical attack (17% and 8.1%, respectively), and sexual coercion (5.6%). Physical attacks related to pregnancy (directed at the abdomen) occurred in 5.4% of the pregnant women. There was no significant difference in the prevalence of the different types of abuse between pregnant and non-pregnant women. Physical attack was associated with socioeconomic status, work status, and degree of religiosity.

Conclusion: Pregnant women were at a similar risk for abuse as non-pregnant women in all abuse categories. Predictors for abuse – socioeconomic status and religiosity – are reviewed primarily in a cultural context.

Sepsis is an inflammatory syndrome caused by infection. Consequently, anti-inflammatory therapies in sepsis have been a subject of extensive research and corticosteroids have been used for years in the therapy of severe infections. However, studies conducted in the 1980s failed to demonstrate any beneficial effects of high dose, short-term steroid therapy in sepsis and this therapy was therefore abandoned during the last decade. Recently, a new concept has emerged with more promising results - low dose, long-term hydrocortisone therapy – and this approach is now being evaluated in the treatment of septic shock. It is supported by the observation that many sepsis patients have relative adrenal insufficiency. Moreover, the anti-inflammatory effects of steroids and their ability to improve reactivity to catecholamines further contribute to their effects in sepsis. Large randomized clinical trials will be required to determine the exact role of corticosteroids in septic shock.

Background: Pterygium is a common disease in Israel. Different surgical techniques are used to manage it with varying degrees of success.

Objectives: To evaluate the efficacy and safety of a conjunctival autograft after excision of pterygium.

Methods: Excision followed by conjunctival autograft was used to treat 40 eyes of 40 patients with pterygium. The surgical results were evaluated retrospectively. Follow-up continued for a median of 296 days (range 6±1,056); 26 cases were followed for more than 100 days (average 418 days) and comprised the study cohort. All reported procedures were performed consequentially and by one surgeon in the Tel Aviv Sourasky Medical Center, Israel between 1 June 1997 and 31 March 2000.

Results: There were two recurrences of pterygium (2/26, 7.7%) 2 months postoperatively. There were no major complications. Super-ficial corneal vessels (without concurrent fibrosis) appeared in 10 of 17 cases sutured with nylon, but none occurred in any of the seven grafts sutured with vicryl (P = 0.068). The average LogMAR-corrected visual acuity of the study group improved slightly, from 6/16.5 to 6/11 (P = 0.003).

Conclusions: Excision of pterygium with a conjunctival autograft is a safe and effective operation, with no procedure-specific added surgical risks. The relatively long surgical time and microsurgical methods required to perform the procedure properly have hindered its acceptance as the mainstream approach to pterygium management. Long-term follow-up is needed for better discernment of the surgical results in Israel.
 

Background: Hepatis C virus infection is presently an exclusion criterion to classify SjoÈ gren's syndrome; however, there are distinct clinicopathologic and biologic similarities between HCV-related and SS-related chronic inflammation of mucosa-associated lymphoid tissue and lymphoproliferation that suggest common pathogenetic pathways.

Objectives: To determine whether a subset of patients with sicca syndrome and HCV infection may present a true primary SS rather than a distinct clinicobiologic entity.

Methods: We extensively characterized 20 consecutive patients with positive anti-HCV antibodies and heavy subjective dry eye and/or dry mouth symptoms, plus positive unstimulated sialometry and/or Shirmer's test. We then compared these features with those in HCV-negative primary SS controls (classified according to the latest American-European Consensus Group Classification Criteria for SS).

Results: Of the 20 HCV-positive patients with sicca manifesta-tions, 12 (60%) had positive anti-SSA/SSB antibodies (3/12 by enzyme-linked immunosorbent assay and 6/12 by immunoblot) and/or positive salivary gland biopsy (at least 1 focus/4 mm2), which met the strict classification criteria for SS, as in the case of HCV-negative SS controls. Comparing the HCV-positive SS subset with HCV-negative SS controls showed similar female to male ratio (11/1 vs. 46/4), major salivary gland swelling (17% vs. 26%), positive antinuclear antibodies (75 vs. 94%) and positive rheumatoid factor (58 vs. 52%). Significant differences (P< 0.05) were seen in mean age (69 vs. 56 years), liver disease (50 vs. 2%), lung disease (25 vs. 0%), anti-SSA/SSB positivity (25 vs. 90%), and low C3 or C4 (83 vs. 36%). HCV-positive SS patients exhibited a trend for more frequent chronic gastritis (50 vs. 22%), fibromyalgia (33 vs. 14%), peripheral neuropathy (33 vs. 18%), purpura (33 vs. 19%) and cryoglobulinemia (33 vs. 6%).

Conclusions: A major subset of HCV-positive patients with definite subjective sicca symptoms and positive objective tests may indeed present a true, though peculiar, subset of SS. There are strict similarities with key clinical, pathologic and immunologic findings of definite HCV-negative SS. Other features appear more characteristic of HCV infection. When also considering that HCV is sialotropic and may be treated, HCV-related chronic sialadenitis represents a unique opportunity to clarify key pathogenetic events occurring in the large majority of HCV-negative SS; and similarities to typical primary SS, rather than differences, should be taken into account.
 

Background: Open neural tube defects are among the most common malformations of the fetus. Secondary prevention by early diagnosis during pregnancy and abortion of affected fetuses result in a marked reduction of NTD incidence at birth. The dramatic effect of folic acid for primary prevention of these defects led to recommendations for folic acid supplementation in women of reproductive age.

Objective: To describe the epidemiologic features of NTD in Israel in 1999±2000.

Methods: A national registry of NTD was begun in 1999. During the years 1999±2000, a non-syndromic NTD was diagnosed in at least 394 pregnancies (166 anencephaly, 166 spina bifida, 43 encephalo-cele, and 19 with other types of NTD). The religious-ethnic affiliation was known in 392 cases (209 Jews and 183 non-Jews).

Results: Despite a marked decline in the rate of NTD at birth in the last few decades, the total rates during pregnancy did not change significantly, demonstrating that the changes were secondary to termination of affected pregnancies. At birth, NTD were almost four times more frequent among non-Jews (3.6 per 10,000 live births for anencephaly and 5.9 for spina bifida) than among Jews (anencephaly 1/10,000 live births, spina bifida 1.4/10,000 live births). The complete data of the registry showed an approximately twofold difference in the overall rates during pregnancy between Jews (anencephaly 5.3, spina bifida 4.6, total 11/10,000 live births) and non-Jews (anencephaly 8.8, spina bifida 10.3, total 22.3/10,000 live births). The registry demon-strated that the significant differences in NTD incidence observed at birth between Jews and non-Jews are secondary to a combined effect of a higher frequency of the malformations among non-Jews and a lower proportion of termination of affected pregnancies among non-Jews.

Conclusions: The data presented here will serve as a basis for evaluating the impact of the Ministry of Health recommendations for folic acid supplementation on the incidence of NTD.
 

Background: Familial multiple lipomatosis is an extremely rare disease. The disease usually does not affect the daily life of FML victims, but they may experience difficulty in performing everyday physical tasks if the lipomas are multiple and large. Inheritance is frequently by autosomal dominant transmission, although cases with recessive inheritance have also been reported.

Objectives: To determine the pattern of inheritance of the disease in a family with 83 members spanning three generations.

Methods: A complete family analysis was performed and all surviving members of the family were examined. Laboratory investiga-tions were conducted in those with FML, including serum lipid, cholesterol and glucose levels, white blood cell count, hemoglobin, erythrocyte sedimentation rate, and renal and hepatic function tests.

Results: There were no consanguineous relationships between spouses in the family. The disease was first seen on the neck of the (male) index patient. This patient had 4 sons, 8 daughters and 60 grandchildren. The disease was established in four of his daughters and two of his sons. One of the female grandchildren whose mother has the disease was also affected. The laboratory findings were normal for all patients.

Conclusion: Our findings showed that a) the disease is transmitted by the autosomal dominant route of inheritance; and b) lipomas observed at an early age may be numerous and large, may diffuse, and sometimes have to be excised surgically.
 

Background: Decreased heparan sulfate proteoglycan content of the glomerular basement membrane has been described in proteinuric patients with diabetic nephropathy. Heparanase is an endo-b-D-glucuronidase that cleaves negatively charged heparan sulfate side chains in the basement membrane and extracellular matrix.

Objectives: To investigate whether urine from type I diabetic patients differs in heparanase activity from control subjects and whether resident glomerular cells could be the source of urinary heparanase.

Methods: Using soluble ³⁵S-HSPG[1] and sulfate-labeled extracellular matrix we assessed heparanase activity in human glomerular epithelial cells, rat mesangial cells, and urine from 73 type I diabetic patients. Heparanase activity resulted in the conversion of a high molecular weight sulfate-labeled HSPG into heparan sulfate degradation fragments as determined by gel filtration analysis.

Results: High heparanase activity was found in lysates of both epithelial and mesangial cells. Immunohistochemical staining localized the heparanase protein to both glomeruli capillaries and tubular epithelium. Heparanase activity was detected in the urine of 16% and 25% of the normoalbuminuric and microalbuminuric diabetic patients, respectively. Urine from 40 healthy individuals did not posses detectable heparanase. Urinary heparanase activity was associated with worse glycemic control.

Conclusion: We suggest that heparanase enzyme participates in the turnover of glomerular HSPG. Hyperglycemia enhances heparanase activity and/or secretion in some diabetic patients, resulting in the loss of albumin permselective properties of the GBM[2].
