Background: Rectal intussusception, rectocele and rectal prolapse are anatomic disorders in obstructed defecation syndrome. A relatively new surgical approach, Stapled Transanal Rectal Resection, was designed to treat these anomalies.

Objectives: To present our preliminary results with this technique.

Methods: Thirty patients with ODS[1] not responding to medical treatment or biofeedback were operated on with the STARR[2] technique. All the patients underwent a complete workup in the Pelvic Floor Unit. The operation was performed according to the technique described elsewhere.

Results: The patients' mean age was 67.1 years, and the median duration of symptoms was 7 years. The mean operating time was 40 minutes (range 35–80 min) and the mean hospital stay was 2 days (range 1–4 days). The mean follow-up was 26 months (range 6–48 months). ODS symptoms were ameliorated in 27 patients (90%), decreased significantly in 18, and in 9 patients the symptoms disappeared. The procedure failed in 3 patients (10%). Complications included minor bleeding that required homeostasis in eight patients during the operation. Three patients had transient tenesmus and five patients had anal pain. There were no cases of mortality or pelvic sepsis.

Conclusions: STARR is an effective and safe procedure for the treatment of obstructed defecation syndrome due to rectal intussusception, rectocele and small rectal prolapse.

Background: Most data on the incidence of rheumatic fever come from hospital records. We presumed that there may be cases of RF[1] that do not require hospitalization, especially in countries with high quality community health care. 

Objectives: To explore the incidence and characteristics of RF using community-based data. 

Methods: A retrospective descriptive study was conducted among the members (more than 450,000) of the Clalit Health Services, Central district, during 2000–2005. The electronic medical files of members up to 40 years old with a diagnosis of RF in hospital discharge letters or during community clinic visits were retrieved. Patients with a first episode of RF according to the modified Jones criteria were included.

Results: There were 44 patients with a first episode of RF. All patients were under the age of 29. The annual incidence among patients aged 0–30 years was 3.2:100,000; the highest incidence was among children aged 5–14 years (7.5:100,000), and in males the incidence was 2.26 times higher than in females. The incidence was higher among patients from large families, of non-Jewish ethnicity, and from rural areas. Twenty-five percent of the patients were both diagnosed and treated in an ambulatory care setting.

Conclusions: Although the incidence of RF in the western world and in Israel is low, the disease still occurs and mainly affects children. Any future estimates of disease incidence should take into account that RF is becoming an ambulatorily treated disease.  

Background: Intravenous tissue plasminogen activator has been approved treatment for acute (≤ 3 hours) ischemic stroke in Israel since late 2004. The Israeli experience with IV tPA[1] is still limited. Several factors may influence the response to IV thrombolysis, including time-to-treatment parameters and tandem internal carotid artery/middle cerebral artery stenosis/occlusion.

Objectives: To compare our experience with IV tPA treatment of patients with acute ischemic stroke to the findings of the SITS-MOST (Safe Implementation of Thrombolysis in Stroke-MOnitoring STudy, international data) and of the Sheba Medical Center (national data) and to compare the early outcome among patients with ischemic stroke in the MCA[2] with and without severe ICA[3] stenosis.

Methods: We obtained demographic data, timing details, stroke severity, hemorrhagic complications, mortality, and early outcome from the records of IV tPA-treated acute ischemic stroke patients.

Results: Fifty-eight patients (median age 69 years, 26 females) with acute ischemic stroke were treated by IV tPA at the Tel Aviv Sourasky Medical Center in 2006–2007. Median time between stroke onset and IV tPA administration was 148 minutes for the Sourasky center, 150 minutes for the Sheba center, and 140 minutes for SITS-MOST. The Sourasky mortality rate was 10.5%. Of the 31 patients who suffered MCA stroke, 8 had severe ipsilateral ICA stenosis. These 8 had significantly lower neurological improvement than the 23 without ipsilateral ICA stenosis (1/8 versus 15/23, P <0.001).

Conclusions: Our data demonstrate fairly similar parameters of IV tPA treatment compared to other centers and suggest that patients with severe ICA stenosis might be less likely to benefit from IV tPA.

Background: The role of alcohol in driver fatalities in Israel is unknown, and monitoring blood alcohol concentration among drivers is not routine. Moreover, over the past decade, self-reported access to and consumption of alcohol in Israel has been on the rise.

Objectives: To use available data to characterize alcohol-related driver fatalities.

Methods: The prevalence of alcohol-related driver fatalities were estimated for 443 drivers, ages 17+ years using data from Israel's National Center for Forensic Medicine for 2000–2004.

Results: Between 8% and 17% of driver fatalities had a BAC[1] ≥ 0.05 g/dl. Most drivers with alcohol exceeding this level were males aged 21–30 years who died on weekends. Recreational and/or medicinal drugs were found in 6%–11% of driver fatalities. Mean BAC among driver fatalities with BAC ≥ 0.05 g/dl was threefold higher than the legal driving limit and appears to be increasing with time.

Conclusions: In light of the evidence suggesting an increasing mean BAC over time as well as reported increasing trends in access to alcohol and consumption, this study should serve as a basis for future research to comprehensively characterize the extent of this problem

Background: Critical limb ischemia is an increasingly common condition that has high surgical morbidity and limited non-surgical options.  

Objectives: To evaluate the use of silicon carbide-coated Motion stents, as compared to reported data for bare metal stents, in elderly patients with infrapopliteal artery stenoses causing critical limb ischemia after failed or complicated percutaneous transluminal angioplasty.

Methods: Between January 2003 and March 2004, 41 stents were inserted into 17 consecutive patients (11 males, 6 females, mean age 82 years, range 75–93) following unsuccessful or complicated PTA[1]. Seven patients had one-vessel run-off, six had two-vessel and four had three vessel run-off. All patients suffered from CLI[2], had up to three lesions and more than one co-morbid condition, and were considered at high surgical risk. Silicon carbide-coated Motion coronary stents, 2.5–4 mm diameter and 25 and 30 mm length, were used. Pre-intervention assessment included clinical condition, ankle brachial index, Doppler ultrasound and digital subtracted angiography. Post-intervention evaluation included clinical condition, ABI[3], and Doppler ultrasound at 3, 6 and 12 months.

Results: The technical success rate per lesion was 100% (41/41). Two patients died of unrelated causes after 2 and 8 months respectively. Primary patency rates with duplex ultrasound were 68.7% (11/16) at 3 months, 43.7% (7/16) at 6 months and 40% (6/15) after 12 months. Nine patients developed complete occlusion in 13 stents; three of these patients underwent a below-knee amputation and two patients a partial foot amputation. Re-intervention (PTA only) was performed in 7 patients (43.7%). Secondary patency rate was 81.2% (13/16) at 6 months and 60% (9/15) at one year. Mean ABI index had improved at 6 months from 0.32 to 0.67, and to 0.53 at one year. Clinical improvement was evident in 87.5% (14/16) at 6 months and in 66.6% (10/15) at one year.

Conclusions: Silicon carbide-coated stents are comparable to bare metal stents after 6 and 12 months in infrapopliteal interventions in CLI when stenting is indicated.

Background: Lung disease in patients with famHiat dys-autonomia is caused mainly by recurrent aspiration of gastric contents, food and liquids swallowed incorrectly.

Objective: To describe chest computed tomography findings in patients with familial dyautonomia.

Methods: A retrospective analysis of chest CT findings was performed for 34 FD patients (15 females, 19 males) with a mean age of 18± 12.8 years.

Results: The CT revealed bronchial wall thickening (in 94% of the patients), atelectasis (in 73%), ground glass opacities (in 53%), focal hyperinflation (in 44%), fibrosis (in 29%) and bronchiectasis (in 26%). The extrapulmonary abnormalities were scoliosis (79%) and esophageal dilatation (35%). Silent fractures were noted in two vertebral bodies and one rib.

Conclusions: Pulmonary changes were consistent with chronic inflammation in the bronchi and interstitial tissues. Ground  glass opacities and fibrosis support the theory that these changes could be due to gastric aspiration. Bronchiectasis is less frequent. Esophageal dilatation with fluid overflow adds to aspiration. Fractures can be asymptomaflc and are often missed.
 

Background: Despite progress in medical and surgical care the mortality rate of congenital diaphragmatic hernia remains high. Assessment of short-term outcome is important for comparison between different medical centers.

Objectives: To evaluate the short-term outcome of infants born with symptomatic CDH[1] and to correlate demographic and clinical parameters with short-term outcome.

Methods: We performed a retrospective cohort study in which demographic, obstetric and perinatal characteristics were extracted from infants' files. For comparison of categorical variables chi-square test and Fisher's exact test were used and for continuous variables with categorical variables the Mann-Whitney test was used. Sensitivity and specificity were estimated by receiver operator curve.

Results: The study group comprised 54 infants with CDH, of whom 20 (37%) survived the neonatal period. Demographic characteristics were not associated with survival. Regarding antenatal characteristics, absence of polyhydramnion and postnatal diagnosis were correlated with better survival. Apgar scores (above 5 at 1 minute and 7 at 5 minutes), first arterial pH after delivery (above 7.135) and presence of pulmonary hypertension were significantly correlated with survival. Also, infants surviving up to 6 days were 10.71 times more likely to survive the neonatal period.

Conclusions: The survival rate of symptomatic newborns with CDH at our center was 37% for the period 1988–2006. Prenatal diagnosis, Apgar score at 5 minutes and first pH after delivery were found to be the most significant predictors of survival. Prospective work is needed to evaluate the long-term outcome of infants with CDH.

Background: Early-onset neonatal sepsis is a major cause of morbidity and mortality among newborn infants.

Objectives: To determine the incidence, type of pathogens and resistance to antibiotics among newborns with early-onset neonatal sepsis, and to identify the risk factors predisposing infants to resistant pathogens in order to reevaluate antibiotic regimens appropriate for resistant bacteria in these high risk neonates.

Methods: We retrospectively studied maternal and neonatal variables of 73 term and near-term infants and 30 preterm infants, born over a period of 10.5 years and exhibiting early-onset neonatal sepsis (positive blood cultures in the first 72 hours of life).

Results: Predominant pathogens in term and near-term infants were gram-positive compared with gram-negative organisms (mostly Escherichia coli) in preterm infants. Mothers of infants with antibiotic-resistant organisms were more likely to have prolonged rupture of membranes and prolonged hospitalization before delivery and to be treated with antibiotics. No trends towards more resistant strains of pathogens were recorded over the 10.5 years of the study period.

Conclusions: Early-onset neonatal sepsis in term infants differs in bacterial species from that in preterm infants, with predominantly gram-positive organisms in term and near-term infants and gram-negative organisms in preterms. Rates of bacterial resistance to the combination of ampicillin and gentamicin, though higher among infants born to mothers with prolonged hospitalization who had been treated with antibiotics, still remained very low in our department. Thus, it seems that our classic antibiotic regimen is still appropriate for both term and preterm newborns.
