 Background: Cervical spondylotic myelopathy is often progressive and leads to motor and sensory impairments in the arms and legs. Canal expansive laminoplasty was initially described in Japan as an alternative to the traditional laminectomy approach. The results of this approach have not previously been described in the Israeli population.

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.

Background: There is a dearth of organs for liver transplantation in Israel. Enhancing our understanding of factors affecting graft survival in this country could help optimize the results of the transplant operation.




Objectives: To report 3 years national experience with orthotopic liver transplantation, and to evaluate patient and perioperative risk factors that could affect 1 year graft survival.

Methods: The study related to all 124 isolated adult liver transplantations performed in Israel between October 1997 and October 2000. Data were abstracted from the medical records. One-year graft survival was described using the Kaplan-Meier survival curve and three multivariate logistic regression models were performed: one with preoperative case-mix factors alone, and the other two with the addition of donor and operative factors respectively.

Results: Of the 124 liver transplantations performed, 32 failed (25.8%). The 1 year survival was lower than rates reported from both the United States and Europe, but the difference was not significant. Of the preoperative risk factors, recipient age ≥ 60 years, critical condition prior to surgery, high serum bilirubin and serum hemoglobin ≤ 10 g/dl were independently associated with graft failure, adjusting for all the other factors that entered the logistic regression equation. Extending the model to include donor and operative factors raised the C-statistic from 0.79 to 0.87. Donor age ≥ 40, cold ischemic time > 10 hours and a prolonged operation (> 10 hours) were the additional predictors for graft survival. A MELD score of over 18 was associated with a sixfold increased risk for graft failure (odds ratio = 6.5, P = 0.001).

Conclusions: Graft survival in Israel is slightly lower than that reported from the U.S. and Europe. Adding donor and operative factors to recipient characteristics significantly increased our understanding of 1 year survival of liver grafts.

 Background: The Israel Defense Forces implemented a pilot teledermatology service in primary clinics.

Objectives: To assess user satisfaction and clinical short-term effectiveness of a computerized store and forward teledermatology service in urban and rural units.

Methods: A multi-center, prospective, uncontrolled, cohort pilot trial was conducted for a period of 6 months. Primary care physicians referred patients to a board-certified dermatologist using text email accompanied by digital photographs. Diagnosis, therapy and management were sent back to the referring PCP[1]. Patients were asked to evaluate the level of the CSAFTD[2] service, effect of the service on accessibility to dermatologists, respect for privacy, availability of drugs, health improvement and overall satisfaction. PCPs assessed the quality of the teledermatology consultations they received, the contribution to their knowledge, and their overall satisfaction.

Results: Tele-diagnosis alone was possible for 95% (n=413) of 435 CSAFTD referrals; 22% (n=95) of referrals also required face-to-face consultation. Satisfaction with CSAFTD was high among patients in both rural and urban clinics, with significantly higher scores in rural units. Rural patients rated the level of service, accessibility and overall satisfaction higher than did urban patients. PCPs were satisfied with the quality of the service and its contribution to their knowledge. Rural physicians rated level of service and overall satisfaction higher than the urban physicians. Tele-referrals were completed more efficiently than referral for face-to-face appointments.

Conclusions: CSAFTD provided efficient, high quality medical service to rural and urban military clinics in the IDF[3].

 Subthalamic nucleus stimulation by means of permanently implanted brain electrodes is a very effective therapy for all the cardinal features of Parkinson’s disease. In appropriate patients, motor improvement is accompanied by a significantly improved quality of life and a reduced necessity for medication. This article briefly reviews the indications, technique and postoperative management of patients undergoing subthalamic nucleus stimulation.

 Background: Foreign workers in Israel are not covered by the comprehensive medical insurance that all Israelis receive. They have national insurance and injury-related coverage, which does not include routine pregnancy follow-up

Objectives: To compare perinatal outcome between partially insured non-resident migrants in Israel and comprehensively insured Israeli women.

Methods: Parameters of perinatal outcome were compared between 16,012 Israeli and 721 foreign women living in Israel. Outcome measures included birth weight, distribution of gestational age at delivery, neonatal complications, cesarean section, neonatal intensive care unit admission, intrauterine fetal death rates, and duration of post-partum hospitalization.

Results: Deliveries prior to 28 weeks gestation occurred more frequently among non-residents (1.3% vs. 0.6%, P < 0.001). Gestational diabetes and preeclamptic toxemia were significantly more prevalent among non-residents (3.2% vs. 1.9%, P < 0.05 and 4.9% vs. 3.1%, P < 0.05, respectively). The cesarean rates were 18% and 35% for residents and non-residents, respectively (P < 0.001), and the post-cesarean recovery period was longer among non-residents (4.8 vs. 3.6 days, P < 0.05). The mean birth weight was similar in the two groups (3,214 vs. 3,231 g), although macrosomia (>4,000 g) was more prevalent among non-residents, who also had higher rates of NICU[1] admission ((9.6% vs. 8%, P < 0.05) and intrauterine fetal death (6.6/1,000 vs. 3.7/1,000, P < 0.05).

Conclusions: Non-resident parturients in Israel are more susceptible to an adverse perinatal outcome than their Israeli counterparts. We suggest that governmental subsidization of non-residents' health expenditures would reduce the differences in perinatal outcome between these two groups.

Background: Heterotopic ossification is a common complication of hip surgery and musculoskeletal or brain traumas.

Objectives: To confirm by in vivo study that colchicine inhibits osteoblast cell proliferation with marked decrease in tissue mineralization.

Methods: Heterotopic ossification was induced in three groups of New Zealand white rabbits (females, 6 months old, weight 3–3.5 kg) by injecting 2 ml bone marrow drawn from the iliac crest into their right thigh muscle. To prevent heterotopic ossification, colchicine (0.25 mg/day) was administered orally for 4 weeks to two groups of adult rabbits: group A (preload group) – 1 week preceding bone marrow injection; group B – on day of injection; and group C – control group.

Results: After 4 weeks the rabbits were evaluated by radiographs and ultrasound for evidence of heterotopic ossification. At the end of the study histologic samples were taken from all the thighs. Imaging and histologic studies showed, with statistical significance, almost complete prevention of heterotopic ossification formation in group A (preload) and a marked decrease in group B, when compared with the controls in whom large new bone had formed at the injection site. These results indicated the inhibitory effects of colchicine on a bone-forming process in soft tissue such as heterotopic ossification.

Conclusions: The role of colchicine in preventing heterotopic ossification in other bone-forming conditions, such as hip arthroplasty or pelvic trauma, and after brain trauma, remains to be evaluated in a clinical setting.

Background: Advances in surgical techniques and retractor-stabilizer devices allowing access to all coronary segments have resulted in increased interest in off-pump coronary artery bypass. The residual motion in the anastomotic site and potential hemodynamic derangements, however, render this operation technically more demanding.

Objectives: To evaluate the OPCAB[1] experience in a single Israeli center.

Methods: Between 2000 and 2003 in our institution, 1,000 patients underwent off-pump operations. Patients were grouped by the type of procedure, i.e., minimally invasive direct coronary artery bypass or mid-sternotomy OPCAB.

Results: One hundred MIDCAB[2] operations were performed. Of the 900 OPCAB, 767 patients received multiple grafts with an average of 2.6 ± 0.6 grafts per patient (range 2–4) and the remaining patients underwent single grafting during hybrid or emergency procedures. In the multiple-graft OPCAB group, complete revascularization was achieved in 96%. Multiple arterial conduits were used in 76% of the patients, and total arterial revascularization without aortic manipulation, using T-graft (35%) or in situ configurations, was performed in 61%. The respective rates for early mortality, myocardial infarction and stroke in the MIDCAB were 1%, 0% and 2%, and 2%, 1.3% and 0.9% in the multiple-vessel OPCAB groups. Multivariate analysis identified renal dysfunction (odds ratio 11.5, confidence interval 3.02–43.8; P < 0.0001) and emergency operation (OR[3] 8.74, CL[4] 1.99–38.3; P = 0.004) as predictors of mortality. The proportion of off-pump procedures increased from 9% prior to the study period to 59%.

Conclusions: The use of OPCAB does not compromise the ability to achieve complete myocardial revascularization. Our procedure of choice is OPCAB using arterial conduits, preferably the 'no-touch' aorta technique.

Background: The infant mortality rate is a health status indicator.

Objectives: To analyze the differences in infant mortality rates between Jews and Arabs in Israel between 1975 and 2000.

Methods: Data were used from the Central Bureau of Statistics and the Department of Mother, Child and Adolescent Health in the Ministry of Health.

Results: The IMR[1] in 2000 was 8.6 per 1,000 live births in the Israeli Arab population as compared to 4.0 in the Jewish population. Between 1970 and 2000 the IMR decreased by 78% among Moslems, 82% among Druze, and 88% among Christians, as compared to 79% in the Jewish population. In 2000, in the Arab population, 40% of all infant deaths were caused by congenital malformations and 29% by prematurity, compared to 23% and 53%, respectively, in the Jewish population. Between 1970 and 2000 the rate of congenital malformations declined in both the Arab and Jewish populations. In the 1970s the rate was 1.4 times higher in the Arab community than in the Jewish community, and in 2000 it was 3.7 times higher.

Conclusion: As in the Jewish population, the IMR in the Arab community has decreased over the years, although it is still much higher than that in the Jewish community. Much remains to be done to reduce the incidence of congenital malformations among Arabs, since this is the main cause of the high IMR in this population.

Background:  Physicians’ decisions regarding provision of life-sustaining treatment may be influenced considerably by non-medical variables.

Objectives: To examine physicians’ attitudes towards end-of-life decisions in Israel, comparing them to those found in the United States.

Methods: A survey was conducted among members of the Israel Society of Critical Care Medicine using a questionnaire analogous to that used in a similar study in the USA.       

Results: Forty-three physicians (45%) responded, the majority of whom hold responsibility for withholding or withdrawing life-sustaining treatments. Preservation of life was considered the most important factor by 31 respondents (72%). The quality of life as viewed by the patient was generally considered less important than the quality of life as viewed by the physician. Twenty-one respondents (49%) considered withholding treatment more acceptable than withdrawing it. The main factors for decisions to withhold or withdraw therapy were a very low probability of survival of hospitalization, an irreversible acute disorder, and prior existence of chronic disorders. An almost similar percent of physicians (93% for Israel and 94% for the U.S.) apply Do Not Resuscitate orders in their intensive care units, but much less (28% vs. 95%) actually discuss these orders with the families of their patients.

Conclusions:  Critical care physicians in Israel place similar emphasis on the value of life as do their U.S. counterparts and assign DNR[1] orders with an incidence equaling that of the U.S. They differ from their U.S. counterparts in that they confer less significance to the will of the patient, and do not consult as much with families of patients regarding DNR orders.
