 Background: The incidence of perinatal, early-onset Group B streptococcal sepsis is very low in Israel and there are no local guidelines for prevention of the disease.

Objectives: To determine to what extent the current Centers for Disease Control guidelines are practiced in Israel, the reasons for their adoption or rejection, and the need for local official guidelines.

Methods: A telephone questionnaire was conducted of all 27 delivery units in Israel. Answers were obtained from 26, either from the clinical director or the senior obstetrician in charge at the time of the interview.

Results: Only in 2 of the 26 delivery units (8%) are the CDC[1] guidelines adhered to exactly; in 6 units they are deliberately rejected, and in 8 units they are not practiced, although they are allegedly implemented. Thus, the CDC guidelines are not practiced in 14 delivery units (54%). Medico-legal consideration is the sole or major reason for adopting these guidelines in 80% (16/20) of the delivery units where they are seemingly implemented. In the majority of these units (18/20) there is readiness to abandon current practice, should local guidelines differ from those of the CDC, provided that local guidelines are issued by an authoritative source.

Conclusion: CDC guidelines are either deliberately rejected or incorrectly practiced in most Israeli delivery units. The medico-legal argument is one of the main reasons for practicing these guidelines. Since the CDC guidelines probably do not apply in Israel, official local guidelines are urgently needed.

Background: Adult-to-adult living donor liver transplantation is becoming an alternative to cadaveric transplantation in urgent and elective settings. Donor selection crucially affects donor safety and recipient outcome.

Objective: To present our algorithm of urgent and elective donor selection.

Methods: Urgent selection is expeditious and protocol‑based. Elective selection permits a comprehensive process. Both include medical, psychosocial and surgical-anatomic evaluations. Liver volumes and vascular anatomy are evaluated with computerized tomographic angiography. Informed consent is obtained after painstaking explanations. Independent institutional committees review and approve all cases.

Results: Between July 2003 and June 2004 we evaluated 43 potential live donors for 12 potential recipients (fulminant hepatic failure, n=5; chronic end-stage liver disease, n=6); primary graft non-function, n=1). Thirty-three candidates (76%) were excluded due to blood type incompatibility (n=14, 42%), incompatible anatomy (n=8, 24%) – including problematic volume distribution (n=2) or vascular anatomy (n=6) – psychosocial issues (n=4, 12%), or medical co-morbidity (n=7, 22%). Five recipients (FHF[1], n=4; chronic ESLD[2], n=1) were successfully transplanted from living donors. In the acute setting, two patients (FHF, PGNF[3]) died in the absence of an appropriate donor (cadaveric or living donor). In the elective group, one patient died of unexpected variceal bleeding and one received a cadaveric graft just before the planned living donor transplantation was performed. One candidate was transplanted overseas and two cases are scheduled. The ratio of compatibility for donation was 34% (10/29) for blood type-compatible candidates.

Conclusions: Donor selection for living donor liver transplantation is a complex, labor-intensive multidisciplinary process. Most exclusions are due to blood type incompatibility or anatomic details. Psychosocial aspects of these donations warrant special attention.

Background: The prognosis of patients with fulminant hepatic failure without timely liver transplantation is dismal. Given the limited availability of cadaveric organs for urgent transplantation in Israel, adult-to-adult living-donor segmental liver transplantation may be the only alternative.

Objectives: To report our initial experience with urgent lifesaving LDLT[1] in this unique scenario.

Methods: Three adult patients with FHF[2] (two of unknown etiology, one with paracetamol intoxication) were transferred from other institutions and admitted to our intensive care unit. Initial treatment and monitoring included intracranial pressure monitoring and hepatic dialysis using the Molecular Adsorbent Recirculating System. Expeditious potential donor selection included medical, psychosocial and surgical evaluation. Liver volume and vascular anatomic compatibility were assessed with computed tomography angiography.

Results: Between July and October 2003 we performed three procedures of urgent adult-to-adult LDLT. The donors (two uncles, one sister) underwent hepatic resection (two right lobes, one left lateral segment) and recovered well. The recipients underwent total hepatectomy with caval preservation, followed by lobar grafting. All recipients recovered and are alive with good liver function and without any neurologic complications.

Conclusions: Urgent adult-to-adult living-donor segmental liver transplantation can be performed safely and timely as a lifesaving procedure in the setting of comatose patients with FHF.

Background: Even operative deliveries defined as “urgent” show marked diurnal variation with a significant increase during regular working hours.

Objective: To investigate the diurnal variation of urgent operative deliveries and its potential implications on the outcome of newborns.

Methods: We conducted a retrospective study of all deliveries in a public hospital from 1 January 1990 to 31 December 1998. Delivery mode variables analyzed were spontaneous vaginal delivery, urgent cesarean section and operative vaginal delivery. Deliveries were stratified hourly throughout the day. The rate of operative deliveries was calculated and the analysis was then performed according to the daily routine shifts of the medical staff. Birth weight and Apgar scores at 1 and 5 minutes were retrieved as outcome measures.

Results: The rate of urgent cesarean deliveries increased significantly between 8 a.m. and 2 p.m. (150%–230%) from that predicted. The lowest rate of urgent cesarean sections was found between 5 a.m. and 6 a.m. (5.3%). Mean birth weight in spontaneous deliveries was higher in the morning hours than during the night shift (3,293 ± 520 g vs. 3,277 ± 510 g, respectively, P < 0.005). Apgar scores of newborns delivered by urgent cesarean section during the morning were higher compared to those delivered during night shifts and the rate of low Apgar scores was lower in the morning than in evening and night shifts.

Conclusions: Our results indicate a marked diurnal variation in urgent operative deliveries, caused perhaps by varying definition of “urgency” according to the time of day.

Background: Radiofrequency ablation has recently become a viable treatment option for unresectable primary or secondary lesions confined to the liver.

Objective: To study the local therapeutic efficacy, side effects and complications of radiofrequency ablation for the treatment of hepatocellular carcinoma and liver metastases This is the first reported experience of radiofrequency ablation for treating malignant hepatic tumors in Israel.

Methods: Fifteen consecutive patients, aged 53–73 years, with 23 lesions (8 patients with HCC[1] and 7 with secondary liver tumors) underwent radiofrequency ablation under general anesthesia. RITA nine-array 5 cm thermal ablation catheter and the model 1500 generator were used. The mean diameter of all tumors was 4.28 cm (range 1–10 cm). Three lesions were 1–3 cm in diameter (small), 17 lesions measured 3.1–5 cm (medium), and 3 measured 5.1–10 cm (large).

Results: Complete necrosis was found in 8 (66%) of 12 HCCs by computed tomography scan. Of the remainder, diffuse tumor recurrence was demonstrated in three lesions (25%) after lipiodol injection and there was one local tumor recurrence. In the metastases group complete necrosis was found in 5 of 11 lesions (45%). One major complication (peritonitis) was treated with antibiotics and four (26%) minor complications (right pleural effusion, small subcapsular hematoma) were monitored.

Conclusions: Radiofrequency ablation appears to be an effective, safe and relatively simple procedure for the treatment of liver tumors.

Background: Despite advances in cancer therapy the treatment of liver tumors remains a challenge. Most patients are poor candidates for surgical resection; both chemotherapy and irradiation have a low success rate and neither is without complications. New minimally invasive techniques for ablation of unresectable tumors have gained attention as effective treatment alternatives. Among these are percutaneous ethanol injection and radiofrequency ablation; both are effective for primary liver tumors and RFA is also effective for hepatic metastases.

Objective: To report our experience with PEI and RFA in the treatment of hepatic lesions.

Methods: The study included 49 lesions in 27 patients: 23 primary lesions in 13 patients treated with PEI and 26 lesions (22 secondary and 4 primary) in 14 patients treated with RFA. PEI was performed on an outpatient basis in the ultrasound suite; RFA was done in hospitalized patients (9 in the ultrasound suite and 4 in the operating room). Patients were followed with triphasic spiral computerized tomography 1 month after treatment and every 3±6 months thereafter.

Results: Complete necrosis was achieved with PEI on the first attempt in 11 of 23 primary lesions (91.3%). In 8.7% (2/23) a second series of treatments was required. Using RFA, complete necrosis was achieved in 85% of lesions (22/26) and partial necrosis in 15% (4/26). Complications included low fever (3 patients), high fever and abscess formation (1 patient), peri-tumoral necrosis (1 patient ) and portal vein thrombosis (1 patient ).

Conclusions: Our preliminary results confirm that PEI and RFA are an effective and safe option for treating hepatic tumors in patients unfit for surgery.
