Background: Current treatment for the eradication of Helicobacter pylori in patients with peptic disease is based on the combination of antibiotic and anti-acid regimens. Multiple combinations have been investigated, however no consensus has been reached regarding the optimal duration and medica­tions.

Objectives: To assess the efficacy of two treatment regimens in patients with peptic ulcer disease and non-ulcer dyspepsia, and to determine the need for gastric mucosal culture in patients failing previous treatment.

Methods: Ninety patients with established peptic ulcer and NUD (with previously proven ulcer) were randomly assigned to receive either bismuth-subcitrate, amoxycillin and metrnida­zole (8AM) or lansoprasole, clarithromycine and metronida­zole (LCM) for 7 days. Patients with active peptic disease were treated with ranitidine 300 mg/day for an additional month.

Results: Eradication failed in 8 of the 42 patients in the 8AM group and in 2 of the 43 patients in the LCM group, as determined by the ¹³C urea breath test or rapid urease test (19% vs. 5%, respectively, P=0.05). Five of these 10 patients were randomly assigned to treatment with lansoprazole, amoxycillin and clarithromycin (LAC) regardless of the culture obtained, and the other 5 patients were assigned to treatment with lansoprazole and two antibacterial agents chosen according to a susceptibility test. Eradication of H. pylon was confirmed by the ‘³C urea breath test. The same protocol (LAC) was used in all patients in the first group and in four of the five patients in the second group. The culture results did not influence the treatment protocol employed.

Conclusions: Combination therapy based on proton pump inhibitor and two antibiotics is superior to bismuth-based therapy for one week. Gastric-mucosal culture testing for sensitivity of H. pylon to antibiotics is probably unnecessary before the initiation of therapy for patients with eradication failure.

Background: Charts of fetal measurements are widely used in the follow-up of pregnant women, however no charts have been constructed for the Israeli population.

Objectives: To establish growth charts for fetal femur size and biparietal diameter.

Methods: A prospective cross-sectional study of 1,422 singleton pregnancies was conducted.

Results: A total of 1,143 pregnancies met the inclusion criteria. Femur length and biparietal diameter were measured. A linear cubic model was fitted to construct growth charts for the different centiles. The charts were compared with previously published data.

Conclusions: We have constructed new fetal measure­ment charts for femur length and biparietal diameter that are unique for the Israeli population. These charts have been found to be similar to those published for other Caucasian populations.
 

Background: Congenital subependymal pseudocysts are incidental findings that are found in 05-5.2% of neonates during postmortem examination or head ultrasonography. In our institution we detected 10 neonates with CSEPC.

Objective: To investigate associated etiological factors, morphologic characteristics and outcome of CSEPC.

Methods: We performed a meta-analysis of the literature on CSEPC (1967-98), including our 10 cases.

Results: A total of 256 cases of CSEPC were analyzed. Ultrasound diagnosed 77.6% of CSEPC 48.8% were bilateral and 53.4% were located in the caudothalamic groove or head of caudate nucleus. Altogether, 93.5% resolved during 1-12 months of ultrasonographic follow-up. Compared to the general neonatal population, the following features were more prevalent in the CSEPC population: prematurity, maternal vaginal bleeding, preeclamptic toxemia, intrauterine growth restriction, asphyxia, fetal cytomegalovirus and rubella infec­tions, congenital malformations, chromosomal aberrations, infant mortality, and neurodevelopmental handicap. The risk for neurodevelopmental handicap was significantly higher when CSEPC were associated with fetal infections, IUGR, malformations and chromosomal aberrations, or persistence of CSEPC during follow-up. CSEPC infants without any of these four conditions had a low risk for neurodevelopmental handi­cap.

Conclusions: CSEPC are morphologic features of various underlying conditions encountered in the fetus. Association of CSEPC with IUGR, fetal infections, malformations and chromosomal aberrations or persistence of CSEPC indicates a higher risk for future neurodevelopmental handicaps, probably because of the deleterious effects on the fetal brain that are inherent in these conditions. A favorable outcome is expected in the absence of these risk factors.
 

Objectives: To compare risk behavior between subjects attending anonymous and confidential clinics for human immunodeficiency virus testing, and to assess whether anonymous testing results in a higher accrual of persons at risk for HIV.

Methods: An anonymous questionnaire that addressed sociodemographic and risk behavior aspects was administered to 140 subjects attending an anonymous clinic and 124 attending a confidential clinic in the Tel Aviv area. A logistic regression analysis was used to compare the effects of various behavioral factors on the probability of attending each clinic.

Results: Chronological age, age at first sexual intercourse and the percent of married subjects were similar in both clinics. However, there was a significant difference in the sex ratio and in educational attainment (85.0% versus 55.6% were males, P< 0.001 and 58% vs. 34% had over 12 years of education, P<0.001, in the anonymous and confidential clinics respectively).

There was a striking difference between the two clinics with regard to sexual experience characteristics: of the subjects reaching the anonymous clinic 21.4% were homosexual and 10.0% bisexual versus a total of 2.6% in the confidential clinic. A logistic regression analysis, comparing the effects of various behavioral factors on the probability of attending each clinic showed that gender (male), high education, homosexuality, number of partners and sexual encounter with sex workers were the strongest predictors for selecting anonymous HIV examination.

Conclusions: Individuals at high risk for HIV, such as homosexuals and bisexuals, prefer to attend an anonymous clinic.
 

Trophic factors such as nerve and fibroblast growth factors are important modulators of 13 cell physiology. These two factors induce the extension of neurite-Iike processes in primary cultures of adult rat 13 cells. Moreover, both NGF and FGF enhance glucose-induced insulin secretion. Since â cells synthesize NGF and pancreatic islet cells produce FGFs, it is possible that autocrine/paracrine interactions may be major regulators of insulin secretion, and impairment of these interactions could lead to pathological states such as diabetes mellitus.

The future promises good news for the treatment of systemic lupus erythematosus, some of which can already be foreseen. Increased knowledge on genes that participate in the predis­position, pathogenesis, pharmacogenetics of, and protection against this disease may permit intervention at this level. Also, better understanding about the role of sex hormones has allowed trials of weak androgens or prolactin inhibitors. New immunomodulators or i mmunosuppresors may enable more precise treatment at the immunoregulatory level, and greater knowledge on the disturbance of circuits has already provided hints and even allowed trials of anti-interleukin-10 antibodies, an IL-10 decreasing agent, tolerance-induction strategies or intervention at the level of T cell co-stimulation, as well as immune ablation with subsequent stem cell transplantation. Autoantibodies can be removed, controlled by means of anti­idiotypes, which are blocked from reaching their target antigen or uncoupled from the tissues they have reached. All these treatment strategies will gradually become decanted in order to achieve the optimal treatment of SEE, which may turn out to be its cure.

Background: Balneotherapy has been successfully used to treat various rheumatic diseases, but has only recently been evaluated for the treatment of fibromyalgia. Since no effective treatment exists for this common rheumatic disease, comple­mentary methods of treatment have been attempted.

Objectives:To assess the effectiveness of batneotherapy at the Dead Sea area in the treatment of patients suffering from both fibromyalgia and psoriatic arthritis.

Methods: Twenty-eight patients with psoriatic arthritis and fibromyalgia were treated with various modalities of bat­neotherapy at the Dead Sea area. Clinical indices assessed were duration of morning stiffness, number of active joints, a point count of 18 fibrositic tender points, and determination of the threshold of tenderness in nine fibrositic and in four control points using a dolorimeter.

Results: The number of active joints was reduced from 18.4+10.9 to 9+8.2 (P< 0.001). The number of tender points was reduced from 12.6+2 to 7.1±5 in men (P<0.003) and from 13.1+2 to 7.5+3.7 in women (P<0.001). A significant improvement was found in dolorimetric threshold readings after the treatment period in women (P< 0.001). No correlation was observed between the reduction in the number of active joints and the reduction in the number of tender points in the same patients (r= 0.2).

Conclusions: Balneotherapy at the Dead Sea area appears to produce a statistically significant substantial improvement in the number of active joints and tender points in both male and female patients with fibromyalgia and psoriatic arthritis. Further research is needed to elucidate the distinction between the benefits of staying at the Dead Sea area without balneotherapy and the effects of balneotherapy in the study population.
