Background: Cigarette smoking is a widespread problem around the world. In Israel, the prevalence of smoking is 23%. Smokers who are Orthodox abstain from smoking during the Sabbath, i.e., from sundown Friday to sundown Saturday, due to a religious prohibition. The prevalence of smoking among Orthodox men is 13%. However, there are no data on patterns of smoking or on the addiction profiles in this population.

Objectives: To explore the smoking patterns, motivation for smoking and nicotine addiction among Orthodox Jewish men, compared to non-Orthodox men, as well as the differences in the urge to smoke and withdrawal symptoms on Saturday versus weekdays in the Orthodox group. 

Methods: The participants completed the Fagerstrom test for nicotine dependence, questionnaires on reasons for smoking and smoking patterns, as well as two brief questionnaires on the urge to smoke and withdrawal symptoms after overnight abstinence on a weekday and after the end of the Sabbath. 

Results: Both groups were strongly addicted to nicotine and there were no differences in the reasons for smoking, withdrawal symptoms and nicotine craving after an overnight abstinence on weekdays. However, religious smokers had low levels of craving for nicotine and few withdrawal symptoms during Sabbath abstinence when compared to weekdays. 

Conclusions: Although we found no difference in the baseline characteristics with regard to nicotine addiction, smoking motivation, urge to smoke and withdrawal symptoms between religious and non-religious groups, the former are able to abstain from smoking during 25 hours of the Sabbath every week with significantly fewer withdrawal symptoms compared to week days.

 

Background: Stereotactic ablative radiation therapy (SABR) is the application of a very high radiation dose to a small treatment volume. It is the new standard of care in medically inoperable early-stage lung cancer. 

Objectives: To report the outcomes of SABR in stage I lung cancer at Sheba Medical Center since its introduction in 2009.

Methods: We conducted a retrospective chart review of patients with stage I lung cancer treated during the period 2009–2015. Survival status was retrieved from the electronic medical records and confirmed with the national registry. Local failure was defined as increased FDG uptake on PETCT scan within a 2 cm radius of the treated region. Toxicity was estimated from medical records and graded according to common toxicity criteria for adverse events (CTCAE) version 4.03. Overall survival and local control were estimated by the Kaplan-Meier method.

Results: During the study period 114 patients were treated for 122 stage I lung cancer lesions. Median follow-up time was 27 months (range 8.2–69.5 months), median age was 76 years. Eighty-two percent of the tumors were stage IA (size ≤ 3 cm). Median survival was 46 months; estimated 3 year overall survival was 59% (95%CI 47–69%) and local control was 88% (95%CI 78–94%). Toxicity included chest wall pain in 8.4% of patients, rib fracture in 0.9%, grade 1–2 pneumonitis in 12%, grade 3 in 12% and grade 5 (death) in 0.9%.

Conclusions: SABR has been successfully implemented at Sheba Medical Center for the treatment of stage I lung cancer in inoperable patients. It is associated with excellent local control, minor toxicity and an acceptable overall survival.

 

Background: During the past 6 years the Israel Defense Forces Medical Corps (IDF-MC) deployed three humanitarian delegation field hospitals (HDFHs) in disaster zones around the globe: Haiti (2010), the Philippines (2013), and Nepal (2015). 

Objectives: To compare the activity of these HDFHs and the characteristics of the patients they served.

Methods: This retrospective study was based on the HDFHs’ operation logs and patients medical records. The study population included both the staff who participated and the patients who were treated in any of the three HDFHs.

Results: The Philippine HDFH was a "hybrid" type, i.e., it was integrated with a local hospital. Both the Haitian and the Nepali HDFHs were the "stand-alone" type, i.e., were completely autonomic in resources and in function. The Nepali HDFH had a larger staff, departed from Israel 4 hours earlier and was active 7 hours earlier as compared to the Haitian one. In total, 5465 patients, 55% of them female, were treated in the three HDFHs. In Haiti, Nepal and the Philippines, disaster-related injuries accounted for 66%, 26% and 2% of the cases, respectively. Disaster-related injuries presented mainly in the first days of the HDFHs' activity.

Conclusions: The next HDFH should be planned to care for a significant proportion of routine medical illnesses. The IDF-MC continuous learning process will enable future HDFHs to save more lives as we "extend a helping hand" to foreign populations in crisis. 

 

Objectives: To estimate the effect of implementation of a safety checklist in an orthopedic surgical department.

Methods: We conducted a single-center cross-sectional study to compare the incidence of complications prior to and following implementation of the Guidelines for Safe Surgery checklist. The medical records of all consecutive adult patients admitted to the orthopedics department at Wolfson Medical Center during the period 1 July 2008 to 1 January 2009 (control group) and from 1 January 2009 to 1 July 2009 (study group) were reviewed. The occurrences of all complications were compared between the two groups.

Results: The records of 760 patients (380 in each group) hospitalized during this 12 month period were analyzed. Postoperative fever occurred in 5.3% vs. 10.6% of patients with and without the checklist respectively (P = 0.008). Significantly more patients received only postoperative prophylactic antibiotics rather than both pre-and postoperative antibiotic treatment prior to implementation of the checklist (3.2% vs. 0%, P = 0.004). In addition, a statistically non-significant 34% decrease in the rate of surgical wound infection was also detected in the checklist group. In a logistic regression model of postoperative fever, the checklist emerged as a significant independent predictor of this outcome: odds ratio 0.53, 95% confidence interval 0.29–0.96, P = 0.037.

Conclusion: A significant reduction in postoperative fever after the implementation of the surgical safety checklist was found. It is possible that the improved usage of preoperative prophylactic antibiotics may explain the reduction in postoperative fever.

Objectives: To describe the phenotypic and genotypic features in five Bulgarian Jewish patients, from different families, with autosomal dominant OPMD.

Methods: We performed clinical follow-up, electrodiagnostic tests and mutation detection. Blood samples were obtained after informed consent and DNA was extracted; measurement of GCG repeats in both PABPN1 alleles and sequencing of OPMD mutations were performed according to standard techniques.

Results: We identified five patients (four females), aged 58 to 71 years, with bilateral ptosis, dysphagia, dysphonia (n=3) and myopathic motor units by electromyography. In all patients we noticed proximal weakness of the upper limbs with winging scapulae in three of them. All cases shared the (GCG)13-(GCG)10 PABPN1 genotype.

Conclusions: OPMD among Bulgarian Jews is produced by a (GCG)13 expansion, identical to the mutation in Uzbek Jews and French Canadians. In addition to the classical neurological and neuro-ophthalmological features, early shoulder girdle weakness is common in Bulgarian Jewish patients; this is an unusual feature during the early stages of OPMD produced by the same mutation in other populations. We suggest that besides the disease-producing GCG expansion, additional ethnicity-related genetic factors may influence the OPMD phenotype. OPMD is a rare disease, and the identification of five affected families in the rather small Bulgarian Jewish community in Israel probably represents a new cluster; future haplotype studies may elucidate whether a founder effect occurred. 

Background: Human milk produced during prolonged lactation (> 1 year) is extraordinarily rich in fat and has a higher energy content than human milk produced during short lactation.

Objectives: To estimate the fatty acid (FA) profile of human milk and to test the hypothesis that the proportion of C12 and C14 (two dietary saturated FA known to most promote hypercholesterolemia) in human milk during prolonged lactation is similar to that in short lactation.

Methods: We conducted a cross-sectional study of 30 mothers of term infants lactating for more than 1 year as compared with 25 mothers of full-term infants who lactated for 2–6 months. Milk was collected by manual expression in mid-breastfeeding.

Results: The two groups did not differ in maternal height, weight, body mass index, diet, infant birth weight and gestational age, but mothers in the prolonged lactation group were significantly older. There was a significant correlation between lactation duration and C12 or C14. The percentage of all FA combined (except for C12 and C14) decreased significantly over time. In contrast, C12:0 and C14:0 combined increased significantly during lactation (R2 = 10.0%, P < 0.03).

Conclusions: Women who lactated for more than 1 year had higher C12 and C14 FA percentages in their milk than women who lactated for 2–6 months.

Background: Staphylococcus aureus infection is a major cause of morbidity and mortality worldwide. Clindamycin is widely used in the treatment of staphylococcal infections; however, it is our impression that in the last few years, inducible clindamycin resistance (ICR) has become more prevalent.

Objective: To assess the prevalence of ICR[1] in methicillin-sensitive Staphylococcus aureus (MSSA) infections among pediatric patients in Israel.

Methods: We reviewed the files of children diagnosed with MSSA[2] infections during the period January 2006 to June 2007 for full antibiogram (including the D-test for ICR), phage typing and randomly amplified polymorphic DNA.

Results: Altogether, 240 MSSA isolates were recovered, mainly from wounds and abscesses. ICR was detected in 62 of 68 erythromycin-resistant/clindamycin-sensitive strains (91%); the ICR rate for the total number of isolates was 26% (62/240). Phage type analysis demonstrated that 38 of 61 ICR isolates

(62%) were sensitive to group 2, compared to 42 of 172 isolates (24%) that did not express ICR (P < 0.01). On randomly amplified polymorphic DNA, phage type 2 isolates expressing ICR belonged to the same clone, which was different from ICR isolates sensitive to other phages and from isolates not expressing ICR.

Conclusions: Inducible clindamycin resistance is common among methicillin-sensitive Staphylococcus aureus in Israeli children. The D-test should be performed routinely in all isolates of MSSA.

Background: Major advances in the treatment of perinatal asphyxial–hypoxic ischemic encephalopathy followed the translation of hypothermia animal studies into successful randomized controlled clinical trials that substantially influenced the current standard of care.

Objectives: To present our preliminary experience with the first cases of clinical application of therapeutic hypothermia for PA-HIE[1] in what we believe is the first report on non-experimental hypothermia for PA-HIE from Israel.

Methods: We reviewed the medical records, imaging scans, electroencephalograms and outcome data of the six identified asphyxiated newborns who were managed with hypothermia in our services in 2008–2009.

Results: All asphyxiated newborns required resuscitation and were encephalopathic. Systemic hypothermia (33.5ºC) was begun at a median age of 4.2 hours of life (range 2.5–6 hours) and continued for 3 days. All six infants showed a significantly depressed amplitude integrated electroencephalography background, and five had electrographic seizures. One infant died (16%) after 3.5 days. Major complications included fat necrosis and hypercalcemia (n=1), pneumothorax (n=1), and meconium aspiration syndrome (n=2). None of the infants developed major bleeding. Neurodevelopmental follow-up of the five surviving infants at median age 7.2 months (4.1–18.5 months) revealed developmental delays (Battelle screening), with their motor scores ranging from -1 to +1 standard deviation (Bayley scale). None developed feeding problems, oculomotor abnormalities, spasticity or seizures.

Conclusions: Our preliminary experience with this novel modality in a large Tel Aviv neonatal service is consistent with the clinical findings of published trials.

Background: A survey conducted among Israel Defense Force primary care physicians in 2001 revealed that they consider patients' needs more than they do organizational needs and that the education PCPs[1] currently receive is inadequate. In 2003 the medical corps initiated a multi-format continuous medical education program aimed at improving skills in primary care medicine.

Objectives: To measure and analyze the effect of the tailored-made CME[2] program on PCPs’ self-perception 3 years after its implementation and correlate it to clinical performance.

Methods: In 2006 a questionnaire was delivered to a representative sample of PCPs in the IDF[3]. The questionnaire included items on demographic and professional background, statements on self-perception issues, and ranking of roles. We compared the follow-up survey (2006) to the results of the original study (2001) and correlated the survey results with clinical performance as measured through objective indicators.

Results: In the 2006 follow-up survey PCPs scored higher on questions dealing with their perception of themselves as case managers (3.8 compared to 4.0 on the 2001 survey on a 5 point scale, P = 0.046), perceived quality of care and education (3.5 vs. 3.8, P = 0.06), and on questions dealing with organizational commitment (3.5 vs. 3.8, P=0.01). PCPs received higher scores on clinical indicators in the later study (odds ratio 2.05, P < 0.001).

Conclusions: PCPs in the IDF perceive themselves more as case managers as compared to the 2001 survey. A tailor-made CME program may have contributed to the improvement in skills and quality of care.

Background: Obesity has become a major public health problem worldwide.

Objectives: To examine the effect of orlistat in promoting weight loss and its specific effect on the visceral adipose tissue and subcutaneous adipose tissue as evaluated by computed tomography.

Methods: A prospective case series study of 10 obese subjects was conducted. The 6 women and 4 men, age 50–67 years (mean 59 ± 8 years), had a mean body mass index of 34.1 ± 3.2 kg/m². All subjects were prescribed a mildly hypocaloric diet (600 kcal/day deficit). In addition, all subjects were treated with orlistat 120 mg 3 times a day for 20.1 ± 7 weeks.

Results: The subjects had lost approximately 8.2 kg each, or 8.4% of their initial body weight. Mean body weight decreased from 98 ± 13 to 89.8 ± 13.6 kg at the last follow-up visit (P = 0.0001) mean BMI[1] decreased from 34.1 ± 3.2 to 30.3 ± 3.9 kg/m² (P = 0.0001), and mean waist circumference from 113.8 ± 11.4 to 107.6 ± 10 cm (P = 0.0006). Mean total abdominal adipose tissue volume, evaluated by computed tomography, decreased from 426 ± 104.3 to 369.8 ± 99.6 mm³ (P = 0.0001). Mean abdominal SAT[2] volume decreased from 251.1 ± 78.8 to 224 ± 81.1 mm³ (P = 0.006), and mean abdominal VAT[3] volume decreased from 176 ± 76.7 to 141.6 ± 67 mm³ (P = 0.0001). Thus, the total abdominal adipose tissue volume for the whole group decreased by 15.4%, and most of this decrease was attributable to the reduction in VAT (24.8%) as opposed to SAT (only 12% reduction) (P = 0.03). The weight reduction that occurred during the study was accompanied by a statistically significant reduction in levels of total cholesterol, low density lipoprotein-cholesterol, triglycerides, and fasting blood glucose.

Conclusions: Our results demonstrate the effect of orlistat in reducing human visceral adipose tissue as evaluated by CT. The benefit of the treatment is further supported by the statistically significant reduction in cardiovascular risk factors.
