Background: Since 2006 more than 60,000 migrants arrived in Israel from the Horn of Africa (HoA: Sudan, Eritrea, Ethiopia). They were detained in prison and screened for tuberculosis (TB) by means of an interview and chest X-ray (CXR).

Objectives: To evaluate the yield of this screening process.

Methods: This cross-sectional study evaluated the validity of CXR in a random sample of 1087 of the 5335 HoA migrants (20.4%) who arrived in 2009, and assessed its related costs.

Results: Sixty-two migrants (5.7%) had CXRs with TB-suspicious findings, and 11 of them were finally diagnosed with TB (17.7% of all TB-suspicious CXRs). TB point-prevalence was 1000 cases per 100,000 migrants (1.0%). As no additional TB cases were diagnosed on arrival, CXR sensitivity, specificity and positive predictive value were 100%, 96.1% and 17.7%, respectively. The interview did not contribute to the detection of migrants with TB. Direct costs related to the detection of single TB cases in prison was 17,970 shekels (US$ 4585), lower than the treating cost of 28,745 shekels ($ 7335). During 2008–2010, 88 HoA migrants who had been screened at the prison after crossing the border were later diagnosed with TB in the community. The average annual TB incidence was 132 cases/100,000 migrants. We traced 56 (63.6%) of the CXRs that were performed during detention. Of those, 41 (73.2%) were unremarkable, 8 (14.2%) were TB suspicious and 7 (12.5%) had non-TB-related abnormalities.

Conclusions: CXR-based screening is a valid and cost-saving tool for screening  HoA migrants for TB; the interview has significant limitations. 

Background: The prevalence of heart failure (HF) is increasing rapidly with high readmission rates, mainly due to fluid retention. Ultrafiltration (UF) is a mechanical method for removing fluids. Introduced only recently in Israel, the skill and experience required for outpatient congested HF patients are scarce.

Objectives: To evaluate the feasibility and safety of UF therapy in congested HF patients in outpatient clinics under a strict protocol of monitoring and therapy that we developed.

Methods: Between April and September 2013 we applied UF in our outpatient clinic to seven chronically congested HF patients with NYHA III-IV who did not respond adequately to diuretics. We administered a total of 38 courses.

Results: On average, 1982 ml fluid per course was removed without significant adverse events and with patients' subjective feeling of improvement. Only two courses were interrupted prematurely due to mechanical problems but were completed without harm to the patients.

Conclusions: Under appropriate professional medical supervision, UF therapy in an outpatient setting is a safe and effective procedure and serves as an additional tool for managing congested HF patients who do not respond adequately to diuretics.

We are overwhelmed by warnings about inevitable geophysical and human problems. Earth is beset by escalating, man-made, environmental crises and our exploding population will eventually lack water, food and vital materials. This suggests, together with increasing poverty, deepening social unrest and advanced techniques for mass killing, that civilization will break down long before atmospheric CO₂ or resistant microbes become catastrophic. Despite intensive searching, life has not been found in space, even though thousands of planets have been found and life there may be as problematic and unpredictable as on Earth. The human brain is already a 'universe', with 85 billion neurons and a hundred trillion synapses, more than the stars in our galaxy. Understanding consciousness, the brain, its aging and pathologies, and eliminating the propensity for human aggression are urgent challenges. During 1958–2012, NASA spent $800 billion. In contrast, the annual cost of brain disease in the U.S. is $600 billion, more than cardiovascular disease and cancer combined. We suggest that a massive switching of financial and human resources is required to explore the full potential of the human brain. Visiting Mars can wait. We further propose a novel two-brain hypothesis: the animal 'brain' evolved as two fundamentally different though interdependent, complementary organs: one electroionic (tangible, known and accessible), and the other, electromagnetic (intangible and difficult to access) – a relatively independent, stable, structured and functional 3D compendium of variously induced interacting EM fields.

Background: A clavicular fracture accounts for 2.6%–5% of adult fractures. Fractures in the middle-third (OTA 15-B) represent 69%–82% of all clavicular fractures. There is no consensus among orthopedic surgeons regarding treatment for these fractures; many support conservative treatment even for displaced middle-third clavicular fractures, while others choose operative treatment.

Objectives: To assess the attitudes of orthopedic surgeons regarding treatment of displaced mid-shaft clavicular fractures.

Methods: We conducted a survey in which we interviewed orthopedic surgeons from various countries during the 2012 EFORT meeting in Berlin. The questionnaire included an X-ray of a displaced middle-third clavicular fracture, as well as questions regarding the surgeon’s proposed treatment plan.

Results: A total of 177 orthopedic surgeons completed the questionnaire; 49% preferred operative treatment for a displaced middle-third clavicular fracture. Among the orthopedic trauma specialists, 58% suggested operative treatment, as did 82% of shoulder specialists. Most surgeons preferred a locking plate for fixation.

Conclusions: The treatment approach for a displaced middle-third clavicular fracture seems to be evenly split between conservative and operative approaches. The tendency toward operative treatment was even more remarkable among orthopedic trauma specialists and shoulder specialists who completed the questionnaire. Most surgeons prefer a locking plate as a fixation system for this type of fracture. 

Background: Hypertrophic cardiomyopathy (HCM) is a familial disease with autosomal dominant inheritance and age-dependent penetrance, caused primarily by mutations of sarcomere genes. Because the clinical variability of HCM is related to its genetic heterogeneity, genetic studies may improve the diagnosis and prognostic evaluation in HCM.

Objectives: To analyze the impact of genetic diagnosis on the clinical management of HCM.

Methods: Genetic studies were performed for either research or clinical reasons. Once the disease-causing mutation was identified, the management plan was reevaluated. Family members were invited to receive genetic counseling and encouraged to be tested for the mutation.

Results: Ten mutations in sarcomere protein genes were identified in 9 probands: 2 novel and 8 previously described. Advanced heart failure or sudden death in a young person prompted the genetic study in 8 of the 9 families. Of 98 relatives available for genotyping, only 53 (54%) agreed to be tested. The compliance was higher in families with sudden death and lower in what appeared to be sporadic HCM or elderly-onset disease. Among the healthy we identified 9 carriers and 19 non-carriers. In 6 individuals the test result resolved an uncertainty about "possible HCM." In several cases the genetic result was also used for family planning and played a role in decisions on cardioverter-defibrillator implantation.

Conclusions: Recurrence of a same mutation in different families created an opportunity to apply the information from the literature for risk stratification of individual patients. We suggest that the clinical context determine the indication for genetic testing and interpretation of the results.

Background: Early detection of glaucoma enables early initiation of treatment. Screening populations at risk is likely to help achieve this goal.

Objectives: To increase public awareness regarding early detection of glaucoma, and estimate the prevalence of increased intraocular pressure (IOP) and optic disk cupping in the screened population.

Methods: A public awareness campaign was carried out in Israel during the 2009 and 2010 World Glaucoma Week, culminating each year in a one-day, free-of-charge screening of individuals in 13 outreach public locations. Screening was performed by 45 ophthalmologists and included a brief medical history, slit-lamp exam with measurement of intraocular pressure (IOP), and evaluation of cup/disk ratio.

Results: A total of 2560 individuals were screened; the mean age was 59 ± 13 years. IOP ≥ 21 mmHg was found in 4.8%, and 12.3% had cupping ≥ 0.5. IOP ≥ 21 mmHg together with cupping ≥ 0.5 were present in 1.4% and this rate increased with age: 3.7% of cases in the age group ≥ 70 years compared to 1% and 0.6% in the age groups 50–69 and < 50 years, respectively (P < 0.001). Likewise, the prevalence of cupping ≥ 0.7 and of IOP ≥ 24 mmHg increased significantly with age. The prevalence of IOP ≥ 21 mmHg increased in cases with a family history of glaucoma in first-degree relatives (10.5% compared to 3.9%, P < 0.001). The prevalence of IOP ≥ 21 mmHg was also increased in diabetic patients (8.3% vs. 4.3% in non-diabetics, P = 0.002). Further ophthalmologic evaluation was recommended to 13% of the screened individuals.

Conclusions: Outreach screening for glaucoma is a valuable tool for detecting glaucoma, pre-perimetric glaucoma, or ocular hypertension in a meaningful number of previously undiagnosed cases. Yet, cost-effectiveness issues should also be considered. The yield of such screening increases with age and seems to be most advantageous in cases with diabetes or a family history of glaucoma. 

Background: Ethiopian immigration to Israel was initiated in 1981. Most immigrants were rural dwellers who migrated first to Addis Ababa or Gondar, where they waited for eligibility status from Israel to leave Ethiopia. Soon after arriving in Israel, all immigrants were offered screening tests for human immunodeficiency virus (HIV) and syphilis.

Objectives: To evaluate the association of age, gender, marital status and length of time spent in urban areas in Ethiopia with the prevalence of HIV and syphilis seropositivity.

Methods: All adult Ethiopian immigrants who arrived at the Jerusalem immigration center between 1999 and 2002 and consented to HIV and syphilis screening tests were interviewed.

Results: Altogether, 678 immigrants (51% females) were screened; 39 (5.8 %) were seropositive for HIV and 33 (4.9%) for syphilis. The length of time the immigrants spent in Ethiopian cities before leaving for Israel was significantly associated with HIV: odds ratio (OR) 2.76, 95% confidence interval (CI) 1.13–6.71, and syphilis seropositivity  OR 3.87, 95%CI  1.56–9.62.

Conclusions: The length of transit time Ethiopian immigrants from rural areas spend in Ethiopian cities is significantly associated with HIV and syphilis seropositivity. Efforts should be made to shorten this time in order to reduce the risk of infection

Objectives: To examine the effect of seasonality, weather and holidays on hip fracture incidence in older adults. The study population comprised 2050 patients aged 65 years or more who sustained a proximal hip fracture.

Methods: The computerized files of the patients were reviewed for trends in incidence by season, precipitation, minimum and maximum temperatures, day of the week, and certain Jewish festivals.

Results: Hip fractures were more likely to occur in the winter than in the summer (P < 0.0001). Factors that significantly correlated with hip fracture were the maximum daily temperature (r = -0.746, P = 0.005) followed by the minimum daily temperature (r = -0.740, P = 0.006) and precipitation (r = 0.329, P = 0.02). There were fewer fractures on Saturdays (the Sabbath) as compared to other days of the week (P = 0.045). Researching the incidence on Jewish festivals, we found an elevated incidence on Passover (P < 0.0001) and a reduced incidence on the Day of Atonement (Yom Kippur) (P = 0.013).

Conclusions: In older people there is an elevated incidence of proximal hip fractures during the winter and on the Jewish festivals. On weekends and on the Day of Atonement the incidence of proximal hip fractures was reduced.

Objectives: To determine the properties of HAM as an antigenic substrate for the detection of autoantibodies in pemphigus vulgaris and bullous pemphigoid.

Methods: Immunomapping and tandem liquid chromatography mass spectrometry were used to delineate the antigenic structure of HAM in 25 pemphigus patients, 41 pemphigoid patients, and 36 controls. Immunoblotting and indirect immunofluorescence were used to study the diagnostic utility of HAM, and the results were compared to those of indirect immunofluorescence on monkey esophagus, immunoblotting using normal human skin, and enzyme-linked immunosorbent assay (ELISA).

Results: Immunomapping demonstrated the presence of all the antigens known to be targeted in autoimmune bullous skin diseases, in both normal human skin and HAM, except for the absence of BP230, and low threshold levels of Dsg1, Dsg3 and Dsc3 in HAM. HAM indirect immunofluorescence demonstrated anti-basement membrane zone antibodies in 48.7% of the pemphigoid patients, and anti-intercellular space antibodies in 72.0% of the pemphigus patients. HAM immunoblotting did not demonstrate anti-BP230 antibodies, but detected anti-BP180 antibodies in 53.6% of the pemphigoid patients. It did not demonstrate anti-Dsg1 and/or anti-Dsg3 antibodies in any of the pemphigus patients. These results were inferior to those of ELISA and monkey esophagus indirect immunofluorescence.

Conclusions: Compared to other studied methods, HAM does not offer advantages in detecting autoantibodies in bullous pemphigoid and pemphigus vulgaris. 

Objectives: To characterize common obstetric anesthesia practices after cesarean deliveries in Israel in order to standardize postoperative pain relief protocols.

Methods: A questionnaire was completed during an interview with every obstetric anesthesia unit in all 25 delivery wards in Israel. Data were gathered on intraoperative anesthesia and analgesia protocols as well as postoperative pain relief protocols. A sub-analysis compared units whose director completed a formal obstetric anesthesia training program with those whose directors did not.

Results: Neuraxial morphine was used routinely in 12% of hospitals. No unit providing intrathecal morphine complied with American Society of Anesthesiologists guidelines for respiratory monitoring after use of neuraxial opioids. Additionally, non-steroidal anti-inflammatory drugs (NSAIDs) were used routinely in only half the wards, while patient-controlled analgesia was used infrequently. Postoperative verbal analog scores were not recorded routinely in 71% of units on postoperative day 1. The unit director's training significantly influenced the unit protocols.

Conclusions: Intrathecal morphine, the gold standard of care in cesarean deliveries, is rarely used, mainly due to shortage of staff and lack of formal obstetric anesthesia training. In addition, NSAIDs are also underused. There is a need for more formal training for obstetric anesthesiologists in Israel.
