Background: Antibiotic treatment of Clostridium difficile infection (CDI) has a high failure rate. Fecal microbiota transplantation (FMT) has proven very effective in treating these recurrences. 

Objectives: To determine which method of fecal microbiota transplantation (upper or lower gastrointestinal) and which type of donor (a relative or unrelated) is superior.

Methods: This is a retrospective analysis of treatment protocols and outcomes in 22 patients with refractory or recurrent CDI who underwent FMT at two Israeli facilities. Each center used a different donor type, stool preparation and method of delivery. The Tel Aviv Sourasky Medical Center used unrelated fecal donors and frozen stool samples and delivered them primarily (92%) via the lower gastrointestinal (GI) tract. Shaare Zedek Medical Center used fresh donor stool of relatives and delivered them primarily (90%) via the upper GI tract.

Results: FMT had an overall 2 month cure rate of 89%. Patients treated with FMT that was executed through the lower GI tract recovered faster from the infection (1.6 ± 1.08 vs. 2.4 ± 1 days for the upper tract, P = 0.03). The results also showed that patients who received lower GI tract FMTs were more likely to be cured of CDI (100% vs. 75% for upper tract FMTs, P = 0.16). Five patients (22%) died of CDI/FMT-unrelated causes and two (10%) died of CDI/FMT-related causes during the study period.

Conclusions: Lower GI tract FMT is a safe and effective treatment for refractory and recurrent CDI, and yields quicker results than upper GI tract FMT.

Background: Sonographic evaluation of congenital skeletal dysplasias is often challenging. Ultrasound may be limited in demonstrating the skeleton and may overlook specific signs of skeletal abnormality. Computed tomography (CT) with 3D reconstruction was proposed as an aid in the diagnosis of skeletal dysplasias.

Objectives: To describe our experience with 3D-CT imaging for the evaluation of suspected skeletal dysplasias.

Methods: The study group comprised 20 pregnant women carrying 22 fetuses, referred for further evaluation by CT following sonographic suspicion of fetal skeletal dysplasia at 17–39 weeks of gestation. Examinations were performed using various CT protocols. Radiation exposure was decreased during the study period, with eventual lowering of the dose to 1–3 mSv. Meticulous review of the skeleton and long bone measurements were performed on 3D reconstructions. For cases of pregnancy termination, the postmortem diagnosis was compared retrospectively with the CT findings.

Results: Very low dose CT protocols provided excellent diagnostic images. Of 22 fetuses suspected of having skeletal dysplasia on ultrasound, 8 were found by CT to be dysplastic and in 7 the pregnancy was terminated. Postmortem findings, when available, concurred with the CT diagnosis. The remaining 14 fetuses within this cohort were found to be normal according to CT and were carried to term.

Conclusions: 3D-CT may be a valuable complimentary imaging tool to ultrasound for the diagnosis of skeletal dysplasias. Using low dose protocols makes this examination relatively safe, and in the appropriate clinical context may assist in making difficult decisions prenatally.

Background: ‘Religious (halachic[1]) infertility’ results from precoital ovulation prior to immersion in a ritual bath (mikveh) 7 days after menstruation, as mandated by Jewish religious law. Previous authors recommended treatment with estradiol to postpone ovulation and enhance pregnancy rates.

Objectives: To evaluate the prevalence of halachic infertility in an ultra-Orthodox Jewish community, and assess the efficacy of estradiol treatment in postponing ovulation and increasing pregnancy rates.

Methods: We reviewed 88 cycles, of which 23 were control cycles and 65 estradiol-treated cycles, and analyzed the files of 23 women who were treated with 6 mg estradiol/day from day 1 for 5 days of the cycle.

Results: The prevalence of precoital ovulation in the infertile population was 21%. Most of the patients (94%) ovulated before day 13 of the cycle. A short follicular phase due to low ovarian reserve or thyroid endocrinopathy was noted in 12% of the patients. While 64% of the women reported consultation with a Rabbinate authority, 68% of the patients sought medical therapy. Estradiol postponed ovulation for at least one day in 89% of the treatment cycles. Ovulation post-mikveh occurred in 73% of estradiol-treated cycles. The pregnancy rate was 12.5% per cycle and the cumulative pregnancy rate 35% per woman. Half the patients reported spotting during estradiol-treated cycles, and this postponed coitus.

Conclusions: Precoital ovulation is a major reason for infertility among observant couples attending fertility clinics. Estradiol treatment is effective in delaying ovulation and restoring fecundity however, it causes some adverse effects that may decrease its effectiveness.

Background: Double balloon enteroscopy is a new technique that enables deep intubation of the endoscope into the small bowel lumen. Through a channel in the endoscope, invasive procedures such as biopsy, polypectomy and hemostasis can be performed, avoiding the need for surgery.

Objectives: To prospectively analyze our results of the first 124 DBEs[1] performed since February 2007.

Methods: The study group comprised all patients who underwent DBE at the Sheba Medical Center between February 2007 and February 2009. Recorded were the patients' demographic data, comorbidities, indications for the examination, results of previous non-invasive small bowel imaging (computed tomography enterography, capsule endoscopy, etc), investigation time, and results of the procedure including findings, endoscopic interventions, complications and pathological report.

Results: A total of 124 procedures were performed in 109 patients. Of the 124 examinations, 57 (46%) were normal and 67 (54%) showed pathology. The main pathologies detected on DBE were polyps (14%), vascular lesions (17.6%) and inflammation (12%). Endoscopic biopsies and therapeutic interventions were required in 58 examinations (46%). A new diagnosis was established in 15% of patients, diagnosis was confirmed in 29% and excluded or corrected in 12%. One complication was observed: a post-polypectomy syndrome that was treated conservatively.

Conclusions: DBE is a safe procedure and has a high diagnostic and therapeutic yield. Most of the examinations were performed under conscious sedation, and only a minority of patients required deeper sedation.

Background: The crowded environment of correctional facilities may enhance infectious diseases transmission, such as tuberculosis.

Objectives: To define the tuberculosis burden in prisons in Israel, a country of low TB[1] incidence (7.9 cases:100,000 population in 2004), in which about 13,000 inmates are being incarcerated annually, and to recommend policy adaptations for TB control.

Methods: All prison clinic lung records from 1998 through 2004 in Israel were reviewed to identify pulmonary TB patients. Additionally, we reviewed TB epidemiological investigation files from one northern prison (years 2002 through 2005) to evaluate possible transmission of the disease.

Results: During the study period 23 Israeli inmates had pulmonary TB (25 cases/100,000 prisoners), which was 3.5 times higher than for the general population. Of those, 18 (78%) were born in the Former Soviet Union and immigrated to Israel after 1990. Four pulmonary TB cases in the evaluated prison were reported, and 22% (149/670) of all inmates and staff were referred for treatment of latent TB infection.

Conclusions: To prevent future TB cases, we recommend new prevention measures, including a symptom questionnaire for all new inmates and selective tuberculin skin testing for inmates infected with human immunodeficiency virus/AIDS, those who inject drugs, and those who emigrated from the former Soviet Union after 1990. New staff should be screened by the two-step tuberculin skin test and annual symptoms questionnaire thereafter. Incarceration may be used as a point of detection for TB and a window of opportunity for treatment in this hard-to-reach population.

Background: Regular physical activity is known to have a beneficial impact on multiple cardiovascular risk factors, but there is no routine provision of exercise training programs to patients after ischemic stroke.

Objectives: To assess the tolerability, safety and effect of an outpatient supervised exercise training program in patients after a non-disabling ischemic stroke.

Methods: Patients discharged home following a minor ischemic stroke (modified Rankin scale; mRS ≤ 2) were referred to a 3 month outpatient supervised exercise training program, performed twice weekly as prescribed by a physiologist and supervised by physical therapy. Exercise capacity was evaluated by the 6 minute walk test, and by the modified Bruce exercise test.

Results: Of the 52 patients who met the selection criteria, 43 underwent supervised exercise training within 2 months of stroke onset and 9 did not (control group). The baseline characteristics were comparable between the two groups. Following the exercise training program, an improvement in exercise capacity was observed manifested by improvement in the 6 minute walk test (444 ± 90 to 557 ± 99 meters in the exercise group vs. 438 ± 101 to 418 ± 126 in the control group; P = 0.002 for the score changes) and in the exercise duration achieved in the modified Bruce test and the metabolic equivalents achieved [9.6 ± 3.7 to 12.4 ± 3.2 minutes and 6.2 ± 2.8 to 8.5 ± 3.4 respectively in the exercise group (n=41) vs. 9.2 ± 3.5 to 8.0 ± 3.4 min and 5.8 ± 1.8 to 5.8 ± 2.8 in the control group (n=7); P = 0.0009 and 0.01 for score changes, respectively].

Conclusions: An outpatient supervised exercise training program after a minor ischemic stroke is feasible, well tolerated and is associated with improvement in exercise capacity. We strongly recommend that an aerobic exercise program be offered to suitable patients after an ischemic stroke.

The most troublesome complication of acute pericarditis is recurrent episodes of pericardial inflammation, which occur in 15–32% of cases. It was recently found that viral infection has a major role, but in many cases the cause is unknown. The optimal method for prevention has not been fully established; accepted modalities include non-steroidal anti-inflammatory drugs, corticosteroids, immunosuppressive agents, and pericardiectomy. Based on the proven efficacy of colchicine in familial Mediterranean fever, several small and large-scale international clinical trials have shown the beneficial effect of colchicine therapy in preventing recurrent pericarditis. Indeed, colchicines-treated patients consistently display significantly fewer recurrences, longer symptom-free periods, and even when attacks occur they are weaker and shorter in nature. It was also found that pretreatment with corticosteroids substantially attenuates the efficacy of colchicine, as evidenced by significantly more recurrences and longer therapy periods. Colchicine is a safe and effective modality for the treatment and prevention of recurrent pericarditis, especially as an adjunct to other modalities, since it provides a sustained benefit superior to all current modalities. The safety profile seems superior to other drugs such as corticosteroids and immunosuppressive drugs.

Background: Coronary heart disease and ischemic stroke are among the leading causes of morbidity and mortality in adults, and cerebrovascular disease is associated with the presence of symptomatic and asymptomatic CHD[1]. Several studies noted an association between coronary calcification and thoracic aorta calcification by several imaging techniques, but this association has not yet been examined in stable angina pectoris patients with the use of spiral computed tomography.

Objectives: To examine by spiral CT the association between the presence and severity of CC[2] and thoracic aorta calcification in patients with stable angina pectoris.

Methods: The patients were enrolled in ACTION (A Coronary Disease Trial Investigating Outcome with Nifedipine GITS) in Israel. The 432 patients (371 men and 61 women aged 40–89 years) underwent chest CT and were evaluated for CC and aortic calcification.

Results: CC was documented in 90% of the patients (n=392) and aortic calcification in 70% (n=303). A significant association (P < 0.05) was found between severity of CC and severity of aortic calcification (as measured by area, volume and slices of calcification). We also found an association between the number of coronary vessels calcified and the presence of aortic calcification: 90% of patients with triple-vessel disease (n=157) were also positive for aortic calcification (P < 0.05). Age also had an effect: 87% of patients ≥ 65 years (n=219) were positive for both coronary and aortic calcification (P = 0.005) while only 57% ≤ 65 (n=209) were positive for both (P = 0.081).

Conclusions: Our study demonstrates a strong association between the presence and severity of CC and the presence and severity of calcification of thoracic aorta in patients with stable angina pectoris as detected by spiral CT.
