Objectives: To evaluate the criteria used to select surgical versus medical management for SICH.

Methods: We retrospectively reviewed the files of 149 consecutive patients admitted with SICH[1] from January 2004 through January 2006 to our medical center. Their mean age was 66 (range 3–92 years), and 62% were male. SICH localization was lobar in 50% of patients, thalamus in 23%, basal ganglia in 15%, cerebellum in 13%, intraventricular in 6%, and pontine in 1%. Mean admission Glasgow Coma Score was 9 (range 3–15). Risk factors included hypertension in (74%), diabetes mellitus (34%), smoking (14%) and amyloid angiopathy (4%). Fifty percent of patients were on anticoagulant/antiplatelet therapy, including enoxaparin (3%), warfarin (7%), warfarin and aspirin (9%), or aspirin alone (34%).      

Results: Craniotomy was performed in 30% of patients, and ventriculostomy alone in 3%. Rebleed occurred in 9% of patients. Six months after the treatment 36% of operated patients were independent, 42% dependent, and 13% had died. At 6 months, 37% of non-operated patients were independent, 15% dependent, and 47% had died.

Conclusions: One-third of the SICH patients, notably those who were experiencing ongoing neurologic deterioration and had accessible hemorrhage, underwent craniotomy. The results are good, considering the inherent mortality and morbidity of SICH.

Background: The model for end-stage liver disease is the best available predictor of waiting list mortality among liver transplant candidates.

Objectives: To validate the applicability of MELD[1] in Israel.

Methods: All candidates awaiting liver transplantation in our institution were followed prospectively since 2002. We measured the concordance (c-statistic) equivalent to the area under the receiver operating characteristic curve in order to assess the predictive power of MELD. Other independent mortality risk factors were identified by a separate multivariate analysis. Mortality rates within different MELD and Child‑Pugh‑Turcotte scores were compared to the original (United States) MELD data.

Results: Of 86 patients listed for transplantation, 40 were transplanted (36 in Israel and 4 abroad). Of the other 46 patients, 24 are alive and still listed, and 22 died (25%, ~7%/year). The area under the ROC[2] curve for MELD score was 0.79 (0.83 USA) compared to a CPT[3] score of 0.71 (O.76 USA). High MELD scores, occurrence of spontaneous bacterial peritonitis, and diagnosis of hepatocellular carcinoma were independent risk factors of mortality. Death rates per mid MELD score (20–29) were significantly higher than the USA results.

Conclusions: MELD is valid in Israel and superior to CPT in predicting waiting list mortality. Although longer waiting time due to organ scarcity is a key factor, death rates in the mid-range (10–29) MELD groups indicate further audit of the care of patients with end‑stage liver disease.

Objectives: To assess the prevalence of reversible and treatable cardiovascular risk factors among 26’477 healthy Israeli adults: 23’339 men and 3138 women aged 25-55 years.

Methods: We collected data during routine examinations performed as part of a screening program for Israel Defense Force personnel.

Objectives: To describe the technique of CEL[1] and present our clinical results in the management of patients with CSM[2] due to multilevel compressive disease.

Methods: All patients undergoing CEL during the period 1984–2000 were identified. Of these, 24 of 25 patients had complete clinical information. Mean follow-up was 18 months (range 4–48). Mean age was 60 years (range 45–72). One patient underwent CEL at three levels, 22 at four to five levels and 1 patient at six levels The primary outcome measure was improvement in spinal cord function (according to the Nurick classification).

Results: Twenty-three (96%) of the patients experienced relief of their symptoms. Of these, 11 patients showed improvement in their Nurick grade, 12 patients were unchanged and one had worsening. Intraoperative complications (epidural bleeding and dural tear) occurred in six patients. Two patients developed a late kyphosis.

Conclusions: Our treatment of choice for multilevel CSM is canal expansive laminoplasty as initially described by Hirabayashi. It provides the ability for posterior surgical decompression without compromising the mechanical stability of the spine. This approach has the benefit of not requiring internal fixation and fusion. Our clinical outcome and surgical complication rate is comparable to other studies in the literature.

Objectives: To compare leukocyte counts and blood levels of various inflammatory cytokines in children and adults diagnosed with community-acquired bronchopneumonia.

Methods: We prospectively evaluated all pediatric and adult patients admitted for bronchopneumonia based on clinical and chest X-ray findings.. Blood was drawn for complete blood count and serum concentration of the following cytokines: granulocyte colony-stimulating factor, interleukins-6, 8 and 10, interferon-gamma, tumor necrosis factor, as well as matrix metalloproteinase-9 and intercellular adhesion molecule-1.

Results: There were 31 children and 32 adults. The patients in both groups had similar parameters of infection severity. None of them required admission to the Intensive Care Unit. Mean (± SD) leukocyte counts in the pediatric and adult groups were 21,018/mm (± 10,420) and 12,628/mm (± 6735) respectively (P = 0.02). Age was inversely correlated with leukocytes in the pediatric group (P = 0.0001). A significant inverse correslation was also found between age and platelet counts. Although cuytokine levels in both groups were not significantly different, age was

Conclusions: The immune response in community-aquired bronchopneumonia is, at least partly, age-dependent.

Background: Emergency room triage of patients presenting with chest pain syndromes may be difficult. Under-diagnosis may be dangerous, while over0diagnosis may be costly.

Objectives: To report our initial experience with an emergency room cardiologist-based chest pain unit in Israel.

Methods: During a 5 week pilot study, we examined resource utilization and ER [1] diagnosis in 124 patients with chest pain of uncertain etiology or non-high risk acute coronary syndrome. First assessment was performed by the ER physicians and was followed by a second assessment by the CPU[2] team. Assessment was based on the following parameters: medical history and examination, serial electrocardiography, hematology, biochemistry and biomarkers for ACS[3], exercise stress testing and/or 64-slice multi-detector cardiac computed tomography angiography. Changes in decision between initial assessment and final CPU assessment with regard to hospitalization and utilization of resources were recorded.

Results: All patients had at least two cardiac troponin T measurements, 19 underwent EST[4], 9 echocardiography and 29 cardiac MDCT[5]. Fourteen patients were referred for early cardiac catheterization (same/next day). Specific working diagnosis was reached in 71/84 patients hospitalized, including unstable angina in 39 (31%) and non-ST elevation myocardial infarction in 12 (10%). Following CPU assessment, 40/124 patients (32%) were discharged, 49 (39%) were admitted to Internal Medicine and 35 (28%) to the Cardiology departments. CPU assessment and extended resources allowed discharge of 30/101 patients (30%) who were initially identified as candidates for hospitalization after ER assessment. Furthermore, 13/23 (56%) of patients who were candidates for discharge after initial ER assessment were eventually hospitalized. Use of non-invasive tests was significantly greater in patients discharged from the ER (85% vs. 38% patients hospitalized) (P < 0.0001). The mean ER stay tended to be longer (14.9 ± 8.6 hours vs. 12.9 ± 11, P = NS) for patients discharged. At 30 days follow-up, there were no adverse events (myocardial infarction or death) in any of the 40 patients discharged from the ER after CPU assessment. One patient returned to the ER because of chest pain and was discharged after re-assessment. 

Conclusions: Our initial experience showed that an ER cardiologist-based chest pain unit improved assessment of patients presenting to the ER with chest pain, and enhanced appropriate use of diagnostic tests prior to decision regarding admission/discharge from the ER.

We describe a unique E3, the F-box protein, Ufo1, of yeast. Ufo1 recruits the mating switch endonuclease, Ho, to the SCF complex for ubiquitylation. In addition to the F-box and WD40 protein-protein interaction domains found in all F-box proteins, Ufo1 has a unique domain comprising multiple copies of the ubiquitin-interacting motif. Ufo1 interacts with the UbL-UbA protein, Ddi1, via its UIMs[1], and this is required for turnover of SCF ^Ufo1 complexes. This is a novel function for an UbL-UbA protein. Deletion of the genomic UFO1 UIMs is lethal and our data indicate that Ufo1ΔUIM acts as a dominant negative leading to inhibition of the SCF pathway of substrate degradation and to cell cycle arrest. Furthermore, we found that Ddi1 is required for the final stages of degradation of Ho endonuclease. In the absence of Ddi1, Ho does not form a complex with the 19S RP and is stabilized. Stabilization of Ho leads to perturbation of the cell cycle and to the formation of multi-budded cells. Our experiments uncover a novel role for the ubiquitin-proteasome system in maintenance of genome stability.

Background: Peritoneal dialysis is a widely accepted route for renal replacement. With the advent of endoscopy, many surgical techniques for the prevention of catheter failure have been proposed.

Objectives: To evaluate the outcomes of patients undergoing laparoscopic Tenckhoff catheter implantation, using the pelvic fixation technique.

Methods: Data analysis was retrospective. All procedures were performed under general anesthesia. A double-cuffed catheter was inserted using two 5 mm trocars and one 10 mm trocar, fixing its internal tip to the dome of the bladder and its inner cuff to the fascia. Catheter failure was defined as persistent peritonitis/exit-site/tunnel infection, severe dialysate leak, migration or outflow obstruction.

Results: LTCI[1] was performed in 34 patients. Mean patient age was 65 ± 17 years. In 12 of the 34 patients the indication for LTCI was end-stage renal failure combined with NYHA class IV congestive heart failure. Operative time was 35 ± 15 minutes. A previous laparotomy was performed in 9 patients. Hospital stay was 1.5 ± 0.6 days. The first continuous ambulatory peritoneal dialysis was performed after 20 ± 12 days. Median follow-up time was 13 months. There were several complications, including 5 (14%) exit-site/tunnel infections, 27 episodes (0.05 per patient-month) of bacterial peritonitis, 3 (9%) incisional hernias, 1 case of fatal intraabdominal bleeding, 2 (5.8%) catheter migrations (functionally significant), and 10 (30%) cases of catheter plugging, 8 of which were treated successfully by instillation of urokinase and 2 surgically. A complication-mandated surgery was performed in 8 patients (23.5%). The 1 year failure-free rate of the catheter was 80.8%. One fatal intraabdominal bleeding was recorded.
Conclusions: LTCI is safe, obviating the need for laparotomy in high risk patients. Catheter fixation to the bladder may prevent common mechanical failures
