Objectives: To assess the implementation of intravenous rt-PA[1] in routine clinical care at our center after its formal approval in Israel, and the therapeutic and logistic implications for reperfusion therapy for acute ischemic stroke in Israel.

Methods: Patients with acute ischemic stroke, admitted between January 2005 and June 2006, who were treated with intravenous rt-PA or endovascular-based reperfusion were reviewed. Implementation, timing, safety and clinical outcomes were assessed.

Results: Forty-six patients received reperfusion therapy (37 with intravenous rt-PA and 9 with endovascular-based therapy), corresponding to 4.0% of ischemic stroke patients in 2005 and a projection of 6.2% in 2006. Mean age of intravenously treated patients was 67 years (range 22–85 years), median baseline NIHSS score was 14 (range 10–18, 25–75%) and the median ‘onset to drug time’ was 150 minutes (range 120–178, 25–75%). Symptomatic intracerebral hemorrhage and orolingual angioedema each occurred in one patient (2.7%). Significant clinical improvement occurred in 54% of treated patients and 38% of patients were independent at hospital discharge.

Conclusions: Use of reperfusion therapy for acute ischemic stroke has increased in our center after the formal approval of rt-PA therapy to over 5%, with ‘onset to drug time’, safety and outcome after intravenous rt-PA treatment comparing favorably with worldwide experience. A prerequisite for the implementation of effective reperfusion therapy and expansion of the proportion of patients treated nationwide is the establishment of a comprehensive infrastructure.

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.

Objectives: To describe patients with initially misdiagnosed PTP[1] and to emphasize the diagnostic pitfalls of this disorder.

Patients and Results: During a period of 11 years we have diagnosed six patients with PTP, four women and two men. The incidence of PTP was approximately 1:24,000 blood components transfused. We present the detailed clinical course of three of the six patients in whom the diagnosis was particularly challenging. The patients were initially misdiagnosed as having heparin-induced thrombocytopenia, systemic lupus erythematosus complicated by autoimmune thrombocytopenia, and disseminated intravascular coagulation. A history of recent blood transfusion raised the suspicion of PTP and the diagnosis was confirmed by appropriate laboratory workup.

Conclusions: PTP seems to be more frequent than previously described. The diagnosis should be considered in the evaluation of life threatening thrombocytopenia in both men and women with a recent history of blood transfusion.

Objectives: To evaluate the safety and efficacy of external counter-pulsation therapy in heart failure patients.

Methods: Fifteen symptomatic heart failure patients (subsequent to optimal medical and device therapy) underwent 35 hourly sessions of ECPT[1] over a 7 week period. Before and after each ECPT session we performed pro-B-type natriuretic peptide and brachial artery function studies, administered a quality of life questionnaire, and assessed exercise tolerance and functional class.

Results: Baseline left ventricular ejection fraction was 28.1 ± 5.8%. ECPT was safe and well tolerated and resulted in a reduction in pro-BNP[2] levels (from 2245 ± 2149 pcg/ml to 1558 ± 1206 pcg/ml, P = 0.022). Exercise duration (Naughton protocol) improved (from 720 ± 389 to 893 ± 436 seconds, P = 0.0001), along with functional class (2.63 ± 0.6 vs. 1.93 ± 0.7, P = 0.023) and quality of life scores (54 ± 22 vs. 67 ± 23, P = 0.001). Nitroglycerine-mediated brachial vasodilatation increased (11.5 ± 7.3% vs. 15.6 ± 5.2%, P =0.049), as did brachial flow-mediated dilation (8.35 ± 6.0% vs. 11.37 ± 4.9%, P = 0.09).

Conclusions: ECPT is safe for symptomatic heart failure patients and is associated with functional and neurohormonal improvement. Larger long-term randomized studies with a control arm are needed to confirm these initial encouraging observations.

Objective: To report our experience with terlipressin treatment for facilitation of transport to distant facilities for diagnostic or therapeutic procedures in septic patients treated with norepinephrine.

Methods:  We conducted a retrospective analysis of the records of our ICU[1], identifying the patients with septic shock who required norepinephrine for hemodynamic support.

Results: Terlipressin was given to 30 septic shock patients (15 females and 15 males) who were on high dose norepinephrine (10 μg/min or more) in order to facilitate their transport outside the ICU. The dose of terlipressin ranged from 1 to 4 mg, with a mean of 2.13 ± 0.68 mg. The dose of norepinephrine needed to maintain systolic blood pressure above 100 mmHg decreased following terlipressin administration, from 21.9 ± 10.4 μg/min (range 5–52 μg/min) to 1.0 ± 1.95 (range 0–10) (P < 0.001). No patients required norepinephrine dose adjustment during transport. No serious complications or overshoot in blood pressure values were observed following terlipressin administration. Acrocyanosis occurred only in eight patients receiving more than 1 mg of the drug. The overall mortality rate was 50%.

Conclusions: Our data suggest that terlipressin is effective in septic shock. Because it is long-acting and necessitates less titration it might be indicated for patient transportation.

Objectives: To investigate the incidence of splenic emboli treated in a single general internal medicine department over the last 3 years.

Methods: We examined the records of a 35 bed internal medicine department in a hospital in the center of Israel.

Results: Over a period of 3 years 13 patients admitted to one internal medicine department developed acute abdominal pain and areas of hypoperfusion in the spleen on contrast computed tomography imaging. The patients were treated with anticoagulants, their course was benign and there were no long-term sequelae.

Conclusions: Embolus to the spleen is not rare in an internal medicine department. Diagnosis can be easily made by contrast CT scanning and treatment with anticoagulants results in a good prognosis. 

Objectives: To determine whether this policy is still applicable. 

Methods: We performed prospective sampling and follow-up of women admitted for labor and delivery between February 2002 and July 2002. Vaginal and rectal cultures were obtained before the first pelvic examination. GBS isolation was performed using selective broth medium, and identified by latex agglutination and serotyping. Demographic data were collected by means of a standardized questionnaire. Data on the newborns were collected throughout 2002.

Results: Of the 629 sampled women, 86 had a positive culture and a carrier rate of 13.7%. A borderline significantly higher carriage rate was observed among mothers of North American origin (21% vs. 13.1%, P = 0.048), and a higher attack rate in their infants (3.8/1000 compared with 0.5/1000 live births in our general maternal population, P = 0.002). Eight newborns had early-onset neonatal GBS sepsis (a rate of 0.8/1000 live births), but none of them benefited from intrapartum antibiotic prophylaxis.

Conclusions: An increased neonatal disease rate was observed in a population with a higher colonization rate than previously seen. In lieu of the higher carrier rates, we now recommend routine prenatal screening for GBS in our perinatal population.
