 Portal hypertension is the leading cause of morbidity and mortality in liver cirrhosis. Complications of portal hypertension in cirrhotic patients include esophageal and gastric varices, portal hypertensive gastropathy, ascites, hepatorenal syndrome, hepatopulmonary syndrome and portopulmonary hypertension. The hepatic venous pressure gradient should be at least 10 mmHg for esophageal varices to appear, and more than 12 mmHg for acute esophageal variceal bleeding. This article reviews the pathophysiology responsible for portal hypertension and its complications, and the treatments used for esophageal varices in the setting of primary and secondary prophylaxis and during active bleeding.

Background: During the horrific war in the Democratic Republic of Congo during the years 1996–2007 the number of casualties is estimated to be 5.4 million. In addition, 1.8 million women, children and men were raped, many as a social weapon of war. Many of these women still suffer from post-traumatic stress disorder (PTSD) and mutilated genitals.

Objectives: To assess a short-term interventional team for the evaluation and treatment of sexual trauma victims.

Methods: The intervention program comprised four components: training the local staff, medical evaluation and treatment of patients, psychological evaluation and treatment of trauma victims, and evacuation and transport of patients with mutilated genitals. A diagnostic tool for post-traumatic stress disorder (PTSD) – the Impact Event Scale (IES) – was used. The psychological treatment was based on EMDR (eye movement desensitization and reprocessing) principles. Using questionnaires, the information was obtained from patients, medical staff and medical records.

Results: Three primary care clinics were chosen for intervention. Of the 441 women who attended the clinics over a period of 20 days, 52 women were diagnosed with severe PTSD. Psychological intervention was offered to only 23 women because of transport limitations.  The most common medical problems were pelvic inflammatory disease and secondary infertility. Nine patients had their genitals mutilated and were transferred for surgical correction. The 32 local nurses and 2 physicians who participated in the theoretical and practical training course showed improved knowledge as evaluated by a written test.

Conclusions: With the short-term interventional team model for sexual assault victims the combined cost of medical and psychological services is low. The emphasis is on training local staff to enhance awareness and providing them with tools to diagnose and treat sexual assault and mutilation.

Background: Chondrosarcoma of the larynx is a rare tumor. The most common symptom is hoarseness. Treatment is controversial.

Objectives: To describe six patients with laryngeal chondrosarcoma from a single center.

Methods: The medical records of a major tertiary hospital were reviewed for all patients with laryngeal chondrosarcoma diagnosed and treated from 1959 to 2010. Data on background, clinical treatment and outcome were collected.

Results: Six patients, all males with a mean age of 53.3 years, were identified. Partial laryngectomy was performed in three patients, and total laryngectomy, local excision, and partial cricoidectomy in one patient each. Four patients had a permanent tracheostomy after surgery. One patient required postoperative chemotherapy and one radiotherapy. Follow-up time was 12–216 months (mean 102 months). Recurrence developed in two patients 2 and 8 years after initial treatment and was treated by salvage surgery in both patients. One patient died during the follow-up from an unrelated cause. The others are currently alive.

Conclusions: This study supports earlier reports recommending initial treatment with partial or total laryngectomy for laryngeal chondrosarcoma. Long-term follow-up for recurrence is advised. We recommend preserving the larynx, if possible, even if a permanent tracheostomy is necessary.

Background: Only 0.5% of stroke patients in Israel are treated with endovascular multi-modal reperfusion therapy (MMRT) each year.

Objectives: To assess our experience with MMRT over the last decade.

Methods: We analyzed data from our stroke registry of patients undergoing MMRT during 2002¨C2011. All patients underwent multi-parametric imaging studies including subtraction angiography according to a predetermined algorithm. Stroke severity was measured with the National Institutes of Health Stroke Scale (NIHSS). Disability was measured with the modified Ranking Scale (mRS) and classified as favorable (mRS ¡Ü 2) or unfavorable. Target vessel recanalization was determined with the thrombolysis in myocardial infarction (TIMI) scale.

Results: During the study period 204 patients were treated 166 of them had complete data sets including mRS scores at 90 days and were included in the analysis. Favorable outcomes at 90 days post-stroke were observed in 37% of patients and the mortality rate was 25%. Patients with favorable outcomes were younger, had significantly lower NIHSS scores on admission and discharge, and more often had complete target vessel recanalization (TIMI 3). On regression analysis the only factor associated with favorable outcome was TIMI 3, whereas increasing age and NIHSS scores on admission and discharge were predictors of poor outcome.

Conclusions: Our data show that MMRT can be successfully implemented in patients with severe stroke in Israel. More than a third of our patients with severe ischemic strokes who could not receive acute treatment were functionally independent after MMRT, demonstrating that this procedure is an important alternative for patients who are not candidates for intravenous tissue plasminogen activator (tPA) or do not achieve recanalization with tPA.

Background: The implantable loop recorder (ILR) is an important tool for the evaluation of unexplained syncope, particularly in cases of rarely occurring arrhythmia.

Objectives: To review the clinical experience of two Israeli medical centers with the ILR. Methods: We reviewed the medical records of patients with unexplained syncope evaluated with the ILR at Rabin Medical Center (2006–2010) and Wolfson Medical Center (2000–2009).

Results: The study group included 75 patients (44 males) followed for 11.9 ± 9.5 months after ILR implantation. Patients’ mean age was 64 ± 20 years. The ILR identified an arrhythmic mechanism of syncope in 20 patients (17 bradyarrhythmias, 3 tachyarrhythmias) and excluded arrhythmias in 12, for a diagnostic yield of 42.7%. It was not diagnostic in 17 patients (22.7%) at the time of explant 26 patients (34.7%) were still in follow-up. In two patients ILR results that were initially negative were reversed by later ILR tracings. The patients with bradyarrhythmias included 9 of 16 (56.3%) with surface electrocardiogram conduction disturbances and 2 of 12 (16.7%) with negative findings on carotid sinus massage. All bradyarrhythmic patients received pacemakers the seven patients for whom post-intervention data were available had no or mild symptoms.

Conclusions: The ILR has a high diagnostic yield. Pre-ILR findings correlating with the ILR results are conduction disturbances (positive predictor of arrhythmia) and negative carotid sinus massage results (negative predictor of arrhythmia). Proper patient instruction is necessary to obtain accurate results. Caution is advised when excluding an arrhythmia on the basis of ILR tracings, and long-term follow-up is warranted.

Background: Pediatric empyema necessitates prompt resolution and early hospital discharge with minimal morbidity. However, the most effective treatment approach is not yet established.

Objectives: To assess the efficacy of an intrapleural streptokinase washing protocol as a non-operative treatment for stage II pediatric empyema as compared to operative decortications, by the number of pediatric intensive care unit (PICU) admissions, length of PICU stay and hospitalization duration.

Methods: We retrospectively evaluated 75 consecutive pediatric empyema cases for the period January 2006 to December 2009. Since July 2007 we have used repeated streptokinase-based pleural washing for stage II patients whose condition did not improve with chest drainage.

Results: Before July 2007, 17 of 23 stage II empyema patients underwent decortication, compared to only 1 of 21 after July 2007. Non-operated children were admitted to the PICU less frequently than those who were operated (83% vs. 31%, P = 0.0006), spent less time in the PICU (2.56 ± 1.92 vs. 1.04 ± 1.9 days, P = 0.0148), with no significant statistical difference in overall hospitalization (13.33 ± 3.69 vs. 11.70 ± 5.74 days, P=0.301).

Conclusions: Using intrapleural streptokinase washing as a non-operative treatment for stage II pediatric empyema yielded comparable success rates to the operative approach, with less morbidity.

Dopaminergic neurons in the basal ganglia normally fire in a continuous manner, maintaining the striatal dopamine concentration at a relatively constant level. In Parkinson’s disease, dopaminergic treatment produces a discontinuous stimulation, inducing an intermittent pulsatile activation of the striatal receptors. Probably the oscillations in the dopamine level in the striatum contribute to the development of motor complications. Treatment with long-acting dopaminergic agents, or providing a more continuous dopaminergic effect in the striatum, has been associated with fewer clinical motor complications. This review describes the state of the art in the clinical approach to achieve the desired continuous dopaminergic stimulation, providing patients with the best clinical effect and probably minimal motor complications.

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.
