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. 

 

Abstract

Background: Gaucher disease is the most common lysosomal storage disorder and is caused by a deficiency of the enzyme glucocerebrosidase. Enzyme deficiency leads to the accumulation of undegraded substrates, mainly in cells of the monocyte/macrophage lineage, which is responsible for the clinical manifestations of the disease. To date, no study has attempted to identify the mutation spectrum of the glucocerebrosidase gene (GBA) in Slovak patients

Objectives: To identify mutations in 14 Slovak patients with confirmed glucocerebrosidase deficiency.

Methods: Using molecular genetics methods PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) and direct sequencing of coding region GBA we identified the spectrum of mutations in our patients.

Results: Five mutations (N370S, L444P, G377S, D409H and RecNciI) accounted for 75% of the mutant alleles. The remaining 25% were rare and probably individual mutations.

Conclusions: The mutational spectrum in our patients is similar to that observed in other European countries and corresponds to a Caucasian population, with N370S, L444P, RecNciI being the most common mutation. Interestingly, mutation G377S was more frequent in our patients as compared to other published data. The C4W, L96P, H311N, 745delG and 1127_1128delTT mutations are described here for the first time in Gaucher disease, contributing to the panel of published GBA mutations.  

Objectives: To assess the current practice in acute flexor tendon repair among Israeli hand surgeons.

Methods: A five-question survey was conducted among certified hand surgeons in Israel regarding their preferred materials and method for performing acute flexor tendon repair.

Results: Forty-eight hand surgeons participated in the survey. The most widely used core suture in zone 2 (58.3%), as well as in zones 3 and 4 (62.5%), was the modified Kessler type. The most widely used suture material was nylon. All surgeons incorporated epitendinous sutures to augment their core sutures. 

Conclusions: The modified Kessler core suture technique is the most widely used technique among Israeli hand surgeons for repairing acute flexor tendon lacerations in zones 2, 3 and 4. This finding agrees with worldwide data and with emerging data attesting to the lower risk of adhesion formation and postoperative tendon ruptures with this method. The core suture technique initially popularized by the late Prof. Isidor Kessler, who headed our department during the years 1973–92, remains the most practiced acute flexor tendon repair technique among hand surgeons in Israel. 

Background: Delays in diagnosis and inadequate treatment of acute scaphoid fractures can lead to non-unions, presenting surgeons with unique challenges regarding optimal management.

Objectives: To evaluate the clinical and radiographic outcome of scaphoid non-unions treated with percutaneous screw fixation.

Methods: The study group comprised12 patients with scaphoid non-unions of an average duration of 8.7 months. There were 11 males and 1 female with an average age of 24 years (range 14–47 years). All patients were initially treated with percutaneous screw fixation without bone grafting. A volar percutaneous approach was used in eight patients and a dorsal percutaneous approach in four. Wrist range of motion (ROM) and disabilities of the arm, shoulder, and hand (DASH) questionnaires were used to assess clinical outcomes. Postoperative radiographs were reviewed to assess the fracture union, carpal alignment and screw position.

Results: Eleven of the 12 (92%) fractures united successfully with no additional procedures. These fractures achieved radiographic union at an average of 4 months. One patient with sickle cell anemia required revision fixation, which consisted of repeat percutaneous fixation and bone grafting. In this patient his non-union healed 3 months after the revision procedure. The average DASH score at final follow-up was 6 (range 0–16). Average wrist ROM was extension of 66 degrees (range 50–80) and flexion 71 degrees (range 55–90). None of the patients showed radiographic signs of osteoarthritis, osteonecrosis of the scaphoid, or hardware-related complications.

Conclusions: For scaphoid waist nonunions without collapse, percutaneous fixation without supplementary bone grafting provides satisfactory results with a high union rate, early return of function and minimal complications.
 

Background: The compliance of hospital staff with guidelines for the active surveillance of methicillin-resistant Staphylococcus aureus (MRSA) in Israel has not been determined.

Objectives: To evaluate the compliance of hospital staff with guidelines for the active surveillance of MRSA and assess its impact on the incidence of nosocomial MRSA bacteremia.

Methods: We assessed compliance with MRSA surveillance guidelines by assessing adherence to the screening protocol and reviewing medical and nursing charts of patients colonized with MRSA, and observed hand hygiene opportunities among health care workers and colonized patients. Rates of nosocomial MRSA bacteremia and of adherence with hand hygiene among overall hospital staff were obtained from archived data for the period 2001–2010.

Results: Only 32.4% of eligible patients were screened for MRSA carriage on admission, and 69.9% of MRSA carriers did not receive any eradication treatment. The mean rate of adherence to glove use among nurses and doctors was 69% and 31% respectively (P < 0.01) and to hand hygiene 59% and 41% respectively (P < 0.01). The hospital overall rate of adherence to hand hygiene increased from 42.3% in 2005 to 68.1% in 2010. Rates of nosocomial MRSA bacteremia decreased by 79.2%, from 0.48 (in 2001) to 0.1 (in 2010) per 1000 admissions (P < 0.001).

Conclusions: The compliance of medical and nursing staff with guidelines for active MRSA surveillance was poor. The encouraging increase in adherence to hand hygiene and concomitant decrease in nosocomial MRSA bacteremia is gratifying. The deficiencies in compliance with MRSA infection control policy warrant an adjusted strategy based on the hospital resources.

Background: Foodborne Salmonella enterica outbreaks constitute both a threat to public health and an economic burden worldwide.

Objectives: To characterize the pathogen(s) involved and possible source of infection of an outbreak of acute gastroenteritis in a banqueting hall in Jerusalem.

Methods: We conducted interviews of guests and employees of the banqueting hall, and analyzed food items, samples from work surfaces and stool cultures.

Results: Of 770 persons participating in three events on 3 consecutive days at a single banqueting hall, 124 were interviewed and 75 reported symptoms. Salmonella enterica, serovar Enteritidis, phage type C-8, was isolated from: 10 stool cultures (eight guests, one symptomatic employee and one asymptomatic employee) and a sample of a mayonnaise-based egg salad. Pulsed-field gel electrophoresis[c1]  of the isolates revealed an identical pattern in the outbreak isolates, different from SE C-8 controls. A culture-positive, asymptomatic employee was linked to all three events. After a closure order, allowing for cleaning of the banqueting hall, revision of food preparation procedures and staff instruction on hygiene, the banqueting hall was reopened with no subsequent outbreaks.

Conclusions: It is often difficult to pinpoint the source of infection in S. enterica outbreaks. Using molecular subtyping methods, a link was confirmed between patients, a food handler, (presumably a carrier) and a food item – all showing an identical specific Salmonella enterica serovar Enteritidis. Testing asymptomatic as well as symptomatic food handlers in outbreak investigations is imperative. Pre- and post-hiring screening might be considered as preventive measures; hygiene and sanitation education are essential.

Background: Secondhand smoke poses a serious health hazard. In Israel The recent passage of a law designed to protect people from secondhand smoke in public places was greeted with controversy. The debate is taking place without data on actual levels of pollution for secondhand smoke in public places.

Objectives: To estimate levels of small respirable suspended particles, atmospheric markers of secondhand smoke, in Israeli bars, pubs and cafes, to compare them with levels in other countries, and to analyze RSP[1] determinants.

Methods: This study was conducted in bars, pubs and cafes in Jerusalem and Tel Aviv prior to passage of the enforcement bill. Venues were randomly sampled from lists available in the local mass media.

Results: The average level of RSPs across all venues, 283 μg/m³, was nearly identical to levels in countries without enforced smoking bans. Bars and pubs had higher values than cafes (P = 0.0101). The effect of smoker concentration was borderline significant (P = 0.0540), with RSP levels increasing as smoker concentration increased. The effect of venue height was also borderline significant (P = 0.0642), with RSP levels decreasing as venue height increased.

Conclusions: Levels of indoor air pollution from secondhand smoke in Israeli bars, pubs and cafes prior to the recent passage of the enforcement bill were similar to levels in countries without enforced smoking bans, and roughly 10 times as high as countries with enforced smoking bans. Whether the new law will successfully promote clean air in Israeli bars, pubs, cafes, and other indoor places is yet to be seen.

Mesenchymal stromal cells are multipotent cells capable of tissue repair and immune modulation. They are primarily found in bone marrow, but are also present in other tissues of mesenchymal origin, such as fatty tissue, muscle, tendons, etc. MSC[1] can easily be obtained by bone marrow aspiration, showing a rapid expansion in vitro. New protocols enable cell culture without the use of animal-derived sera and artificial growth factors. Avascular necroses of the bone may have different causes. AVN[2] in autoimmune and hematological diseases show a strong association with corticosteroid treatment, which is often unavoidable in severe cases. Until recently, core decompression of the affected osseous area was the standard approach. Because of their differentiation properties, easy accessibility and proliferative capacity, autologous MSCs could potentially complement AVN treatment by adding fresh “osteogenic cells” to the healing process.
