Background: The QT interval reflects the total duration of ventricular myocardial repolarization. Disturbed QT – either prolonged or shortened – is associated with arrhythmia and is life-threatening.

Objectives: To investigate an elderly population for disturbed QT interval.

Methods: We conducted a cross-sectional study on residents of long-term care wards in a geriatric hospital. Excluded were those with pacemaker, atrial fibrillation or bundle branch block. The standard 12 lead and lead 2 electrocardiograms in the patients’ files were used for the evaluation of QT interval.

Results: We screened the ECGs of 178 residents. QTc prolongation based on the mean 12 ECG leads was detected in 48 (28%), while 45 (25%) had prolonged QTc based on lead L2. Factors associated with QT prolongation were male gender, chronic renal failure and diabetes mellitus. Short QT was found in 7 residents (4%) and was not related to any parameter.

Conclusions: About one-third of the elderly long-term care residents in our study had QT disturbances. Such a considerable number warrants close QT interval follow-up in predisposed patients.

Background: Amyloidosis of familial Mediterranean fever (FMF) may lead to end-stage renal failure, culminating in kidney transplantation in some patients.

Objectives: To assess demographic, clinical and genetic risk factors for the development of FMF amyloidosis in a subset of kidney-transplanted patients and to evaluate the impact of transplantation on the FMF course.

Methods: Demographic, clinical and genetic data were abstracted from the files, interviews and examinations of 16 kidney-transplanted FMF amyloidosis patients and compared with the data of 18 FMF patients without amyloidosis.

Results: Age at disease onset and clinical severity of the FMF amyloidosis patients prior to transplantation were similar to FMF patients without amyloidosis. Compliance with colchicine treatment, however, was much lower (50% vs. 98 %). Post-transplantation, FMF amyloidosis patients experienced fewer of the typical serosal attacks than did their counterparts (mean 2214 days since last attack vs. 143 days). Patients with FMF amyloidosis carried only M694V mutations in the FMF gene, while FMF without amyloidosis featured other mutations as well.

Conclusions: Compliance with treatment and genetic makeup but not severity of FMF constitutes major risk factors for the development of amyloidosis in FMF. Transplantation seems to prevent FMF attacks. The protective role of immunosuppressive therapy cannot be excluded.

Background: The association between familial Mediterranean fever (FMF) and increased risk for ventricular arrhythmias is controversial, and data on this subject are meager.

Objectives: To evaluate QT variability index (QTVI) and other repolarization markers associated with arrhythmogenity in patients with amyloidosis of FMF.

Methods: The study group comprised 12 FMF patients with amyloidosis, and 14 age and gender-matched healthy subjects served as the control group. QT measurements were conducted according to accepted procedure, using computerized software for recording and analysis.

Results: No differences were found in clinical and demographic parameters in the study and control groups, except for hypertension which was more common in the FMF amyloidosis group. QTc and power spectral analysis of QT variability parameters were similar in both groups. Nevertheless, QTVI values in FMF amyloidosis patients were significantly higher than in healthy individuals (-1.02 ± 0.38, vs. -1.36 ± 0.32 respectively, P = 0.02).

Conclusions: Compared with healthy controls, amyloidosis of FMF is associated with increased QTVI. It remains unknown whether this finding is solely amyloidosis related and whether it has any prognostic significance.

The Warsaw Ghetto, in existence from 1940 to 1943, was the largest ghetto in Nazi-occupied Europe. The 400,000–500,000 Jews incarcerated within its walls were deprived not only of food and medicine but also of education. Nonetheless, Jewish physicians served the community as befits their profession, and against all odds obtained permission to conduct a course on sanitary measures to combat epidemics, which they transformed into a veritable, clandestine medical school. This review follows the fate of the school faculty, with an emphasis on the achievements of the survivors.

Background: The triple test serum markers for Down’s syndrome screening may be altered because of various conditions other than chromosomal trisomies.

Objectives: To assess the profile of mid-trimester triple test serum markers in a cohort of women treated with low molecular weight heparin (LMWH) for thrombophilia since the first trimester.

Methods: Women with inherited or acquired thrombophilia treated with LMWH prior to 12 weeks gestation were followed between October 2006 and September 2009 at our obstetric outpatient clinic. The second-trimester screening test for Down syndrome was calculated from the combination of triple serum markers and maternal age, and expressed as a multiple of the gestation specific normal median (MoM). Reference MoM values were calculated from the local population. Data on pregnancy outcome were obtained from patient records.

Results: The median human chorionic gonadotrophin (hCG) level of women with inherited thrombophilia was 0.87 MoM, compared to 0.99 MoM in controls (P = 0.038) and compared to 1.355 MoM in women with acquired thrombophilia (P = 0.034). In contrast, alpha-fetoprotein MoMs did not differ significantly between women with inherited and women with acquired thrombophilia (0.88 vs. 0.99 MoM, P = 0.403).

Conclusions: The triple test serum markers may be altered in thrombophilia patients treated with LMWH. Clinicians should consider offering these patients the first-trimester nuchal translucency test and other sonographic markers that are probably unaffected by the underlying maternal disease and/or treatment modality.

Background: The increase in human immunodeficiency virus (HIV) among men who have sex with men (MSM) in Israel during the last decade raises concerns regarding other sexually transmitted diseases (STD) in MSM, which are yet undetermined.

Objectives: To evaluate the STD burden in MSM and heterosexuals visiting the Tel Aviv walk-in STD clinic.

Methods: Records of all male patients who attended the clinic once were reviewed to identify demographic characteristics, behavioural attributes, and test results.

Results: Between 2002 and 2008, 1064 MSM (22%) and 3755 heterosexuals (78%) visited the clinic once. Positivity rates in MSM for HIV, urethral Neisseria gonorrhoea and infectious syphilis were higher than in heterosexuals (2.5%, 2.5%. 0.7% vs. 0.6%, 1.3%, 0.3%, respectively), while urethral Chlamydia trachomatis was higher in heterosexuals than in MSM (2.7% and 1.4%, respectively). MSM tested in our clinic were younger than heterosexuals (P < 0.001), more commonly circumcised (P = 0.03) and Israeli-born (P < 0.001), used substances during sex (P = 0.04), and had prior STD (P < 0.001), a greater number of sexual partners (P < 0.001), and earlier sexual debut (P = 0.02). The final multivariate results for MSM to be diagnosed with HIV/STD were greater number of sexual contacts, previous diagnosis with STD, and infrequent use of condom during anal intercourse.

Conclusions: MSM visiting the Levinsky Clinic had higher rates of HIV/STD than heterosexual males, which correlated with their higher-risk behaviors. The unique characteristics of MSM found in our study, such as sex work, substance use, previous diagnosis of STD, multiple partners and inconsistent use of condom during anal sex should be addressed with innovative interventions to prevent STD/HIV in the gay community in Israel.

Background: Outbreaks of syphilis have been described among men who have sex with men (MSM) in many western urban communities in the last few years.

Objectives: To describe the first reported outbreak of syphilis among MSM in Israel within a decade of a constant increase in human immunodeficiency virus (HIV) prevalence.

Methods: All patients diagnosed with syphilis were contacted and asked about their sexual behavior, substance use and previous infections. All were tested for HIV and a phylogenetic analysis was performed. 

Results: A total of 23 (59%) of all 39 male patients diagnosed with primary or secondary syphilis between August 2008 and August 2009 were interviewed. All were MSM and performed anal intercourse, while 13 (55%) reported unprotected anal intercourse. Most participants (21, 91%) practiced unprotected oral intercourse. Nine participants (39%) reported unprotected oral intercourse while using condoms during anal intercourse. Ten participants (43%) reported sexual contacts while traveling abroad in the previous few months. Most participants (96%) were co-infected with HIV, and 15 (68%) were already aware of their HIV infection. Fifteen (66%) reported the use of recreational drugs, alcohol, or both before or during sex. No common source or core transmitters were identified.

Conclusions: This syphilis outbreak included MSM who were co-infected with HIV and were characterized by risky sexual behavior including multiple partners, unprotected anal intercourse and substance use. Future targeted interventions should focus on HIV-infected MSM for secondary prevention.

Background: Pediatric empyema necessitates prompt resolution and early hospital discharge with minimal morbidity. However, the most effective treatment approach is not yet established.

Objectives: To assess the efficacy of an intrapleural streptokinase washing protocol as a non-operative treatment for stage II pediatric empyema as compared to operative decortications, by the number of pediatric intensive care unit (PICU) admissions, length of PICU stay and hospitalization duration.

Methods: We retrospectively evaluated 75 consecutive pediatric empyema cases for the period January 2006 to December 2009. Since July 2007 we have used repeated streptokinase-based pleural washing for stage II patients whose condition did not improve with chest drainage.

Results: Before July 2007, 17 of 23 stage II empyema patients underwent decortication, compared to only 1 of 21 after July 2007. Non-operated children were admitted to the PICU less frequently than those who were operated (83% vs. 31%, P = 0.0006), spent less time in the PICU (2.56 ± 1.92 vs. 1.04 ± 1.9 days, P = 0.0148), with no significant statistical difference in overall hospitalization (13.33 ± 3.69 vs. 11.70 ± 5.74 days, P=0.301).

Conclusions: Using intrapleural streptokinase washing as a non-operative treatment for stage II pediatric empyema yielded comparable success rates to the operative approach, with less morbidity.

Background: While myoclonus and ataxia are considered common in patients with familial Creutzfeld-Jakob disease (fCJD), other movement disorders are less prevalent.

Objectives: To systemically evaluate the frequency of extrapyramidal signs and movement disorders in patients with fCJD.

Methods: A detailed neurological examination, with special emphasis on movement disorders and extrpyramidal signs, was conducted in 43 consecutive symptomatic CJD patients (26 males and 17 females mean age 58.7 ± 8.9 yrs, range 43–77 years) carrying the E200K mutation in the PRNP gene.

Results: Limb or gait ataxia was noted in 38 patients (88%) (37 patients, 86%, had ataxia at presentation). Myoclonus was evident in 25/43 patients (58%) (21 patients, 49%, at presentation). In 95% of the patients (41/43) (37/43, 86% at presentation) at least one extrapyramidal sign throughout the disease course was noted, the most prevalent being rigidity (28/43, 65% of the patients and 22/43, 51% at presentation), followed by the glabellar sign (24/43, 56% of the patients and 22/43, 51% at presentation), bradykinesia (19/43, 44% and 15/43, 35% at presentation), dystonia (15/43, 35% 12/43, 28% at presentation) and tremor (13/43, 30% 12/43, 28% at presentation).

Conclusions: In this unique population of fCJD patients, myoclonus was less prevalent than previously reported while other extrpyramidal signs were common and occurred at a relatively early stage of the disease. The high prevalence of movement disorders can be added to other phenomena characteristic of this familial disorder among Libyan Jews. Whether this is attributable to the E200K mutation itself or to some other mechanism has still to be elucidated.

Dopaminergic neurons in the basal ganglia normally fire in a continuous manner, maintaining the striatal dopamine concentration at a relatively constant level. In Parkinson’s disease, dopaminergic treatment produces a discontinuous stimulation, inducing an intermittent pulsatile activation of the striatal receptors. Probably the oscillations in the dopamine level in the striatum contribute to the development of motor complications. Treatment with long-acting dopaminergic agents, or providing a more continuous dopaminergic effect in the striatum, has been associated with fewer clinical motor complications. This review describes the state of the art in the clinical approach to achieve the desired continuous dopaminergic stimulation, providing patients with the best clinical effect and probably minimal motor complications.

Hip arthroscopy is one of the most rapidly evolving arthroscopy techniques. It combines the benefits of a minimally invasive procedure and a short rehabilitation period. Improved instrumentation and technical skills have advanced our ability to accurately diagnose and treat various conditions. The role of this procedure continues to evolve with new indications that might change the outcome of degenerative joint disease of the hip joint. Hip arthroscopy is indicated for both traumatic and atraumatic intra and extra-articular conditions. Femoroacetabular impingement (FAI) is increasingly recognized as a disorder that can lead to progressive articular chondral and labral injury. A variety of arthroscopic techniques allows the treatment of labral and acetabular rim pathology as well as peripheral compartment femoral head-neck abnormalities. It is now recognized that labral tears that were traditionally treated with simple debridement are often associated with underlying FAI. Hip arthroscopy is also being used for surgery to the structures surrounding the hip as snapping hip syndromes, greater trochanteric pain syndrome, and arthroscopic repair of abductor tendon tears. Better understanding of the arthroscopic anatomy, improved operative techniques, lowered complication rate and objective outcome measuring tools will further define the optimal role of hip arthroscopy and improve its outcome.
