Objectives: To assess the reasons given by gynecologists why they failed to insert a LNG-IUS.

Methods: We obtained data from the sole distributor in Israel that prospectively recorded these cases when contacted by gynecologists following an insertion failure.

Results: The mean rate of failed insertions was 0.95% (range 0.77–1.03%) for the 5 year study period 2006–2010. The most common reasons reported by gynecologists for LNG-IUS insertion failure were loss of sterility of the device, inability to insert the device due to a stenotic cervical canal, accidental removal of the device following a successful insertion due to hasty removal of the inserter or the use of blunt scissors, and removal of the newly inserted LNG-IUS following ultrasound evidence that it was misplaced.

Conclusions:  Gynecologists should be aware of the common pitfalls associated with insertion of an LNG-IUS. Several techniques that may aid in avoiding these mishaps are described.

 Background: Hemorrhagic radiation cystitis (HRC) is a significant clinical problem that occurs after pelvic radiation therapy and is often refractory.

Objectives: To evaluate the efficacy and safety of hyperbaric oxygen therapy (HBO) for HRC.

Methods: Daily 90 minute sessions of HBO at 2 ATM 100% oxygen were given to 32 HRC patients with American Society of Therapeutic Radiology and Oncology (ASTRO) grades 3-4 hematuria.

Results: The median age was 72.5 (48–88 years). The median time interval between radiation therapy and HBO was 4 years (1–26 years). The patients received a median of 30 HBO sessions (3–53). Hematuria resolved in 27 patients (84%) and persisted in 5. Cystectomy was required in two, and ileal-conduit and bilateral percutaneous nephrostomies were performed in one and two patients, respectively. With a median follow-up of 12 months (5–74 months), the hematuria cleared completely in 16 patients (59%) and mild hematuria requiring no further treatment recurred in 10 others. Another patient with ASTRO grade 4 hematuria needed bladder irrigation and blood transfusions. Complications included eardrum perforation in four patients and transient vertigo and mild hemoptysis in one case each. None of them required HBO discontinuation.

Conclusions: HBO controlled bleeding in 84% of the patients. A durable freedom from significant hematuria was achieved in 96% of the patients. HBO seems to be an effective and safe modality in patients with HRC.

Objectives: To determine the effect of the Dead Sea climatotherapy on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

Methods: A total of 119 patients participated in an observational prospective study carried out at the Deutsches Medizinisches Zentrum clinic, a medical skin care center specializing in climatotherapy. The patients completed questionnaires (Skindex-29) to quantify their quality of life at different time points: the day of arrival, the day of departure, and 3 and 6 months after the end of treatment.

Results: Marked improvement in the quality of life scores was measured between the time of arrival to time of departure and to 3 months after the end of treatment.

Conclusions: Dead Sea climatotherapy has a significant positive influence on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

Background: Takayasu arteritis (TA) is a rare chronic granulomatous inflammatory disease of the aorta and/or its major branches and more frequently affects female patients before menopause. Since persistent inflammation may lead to arterial ischemia, hypertension is an important complication of TA. Objectives: To evaluate gestational results and complications in patients with TA arteritis.

Methods: We conducted a retrospective analysis of the medical records of patients with TA admitted to the high risk pregnancy clinic for women with systemic autoimmune diseases at Hospital Universitário Pedro Ernesto.

Results: From 1998 to 2011 we followed 11 pregnancies in 9 patients with TA; the patients’ age ranged from 17 to 42 years and disease duration from 2 to 28 years. In 7 of the 11 pregnancies, uncontrolled blood pressure occurred before labor and preeclampsia was diagnosed in one. Two deliveries were preterm, one newborn was treated for sepsis and four (36%) had intrauterine growth restriction (IUGR).

Conclusions: Close monitoring improves the perinatal outcomes in patients with TA who are more prone to develop hypertension, preeclampsia and IUGR. Disease activity was not observed in our group of patients during pregnancy. Coordinated care between the obstetric, rheumatologic and cardiologic teams is the ideal setting to follow pregnant women with TA.

Background: Despite decades of research on religious determinants of health, this subject has not been systematically investigated within Jewish populations, in Israel or the diaspora. The present paper is part of a series of studies using large-scale population data sources to map the impact of religiousness on the physical and mental health of Jews.

Objectives: To identify religious predictors of physical health in a national probability sample of older Israeli Jews.

Methods: The data derive from the Israeli sample of the Survey of Health, Ageing and Retirement in Europe (SHARE), a cross-national survey program involving nearly a dozen nations. The Israeli sample comprises 1287 Jewish respondents aged 50 or over. Outcome measures include single-item assessments of self-rated health, long-term health problems and activity limitation, as well as validated measures of diagnosed chronic diseases, physical symptoms, and activities of daily living (ADL) and instrumental ADL (IADL).

Results: Recent synagogue attendance is a significant predictor of better health for six of the seven health measures, even after adjusting for age and several other covariates and mediators, including measures of health-related behavior and social support. Prayer, by contrast, is inversely associated with health according to five measures, perhaps reflecting its use as a coping mechanism for individuals with health problems.

Conclusions: This study presents modest evidence of a salutary effect of Jewish religiousness on this population of older adults. Religiousness, in the form of synagogue participation, was seen to serve a protective function, and prayer a coping function.

Background: Atherosclerosis is a well-established inflammatory disease in which T helper 1 (Th1) cells play a key role. Regulatory T (Treg) cells drive a shift from Th1 to Th2 response and were shown to be reduced in atherosclerosis. ST2/interleukin (IL)-33 signal was found to promote Th2 response, attenuating atherosclerotic plaque progression.

Objectives: To evaluated the effect of IL-33 on Treg cell number.

Methods: We employed flow cytometry to determine Treg cell number, as well as ST2 levels, among splenocytes of C57BL/6J vs ApoE-/- mice. Soluble ST2 (sST2) levels were detected by enzyme-linked immunosorbent assay. 

Results: IL-33 contributed to an increase in Treg cells, but this association was attenuated in ApoE knockout (ApoE-/-) atherosclerotic mice. As a possible mechanism we demonstrated a reduction in the levels of CD4+ST2+ cells by flow cytometry, which is cotemporary to the previously described decrease in Treg cells in ApoE-/- mice. Additionally, the serum level of the soluble ST2 (sST2) decoy receptor was higher in ApoE-/- mice than in control animals.

Conclusions: Our results suggest that a repressed ST2/IL-33 signaling may contribute to the decrease in Treg cells observed in atherosclerosis.
 

Background: Understanding the mechanism and the main components involved in rheumatic mitral regurgitation (MR) associated with dominant pliable mitral stenosis (MS) may improve our ability to repair some mixed rheumatic mitral valve pathologies.

Objectives: To assess mitral valve structural components in pure mitral stenosis versus mitral stenosis associated with mild regurgitation

Methods: Using two-dimensional echocardiography, we performed mitral valve structural analysis in two groups of patients prior to balloon mitral valvuloplasty (BMV). The first group, consisting of 13 females and 2 males (mean age 39 ± 5 years), suffered from pure pliable mitral stenosis (PPMS), while the second group, with 22 females and 2 males (mean age 44 ± 5 years), had mixed mitral valve disease (MMVD) characterized by mild MR in the presence of dominant pliable MS. All echocardiographic measurements relating to the mechanism of MR were undertaken during the systolic phase.

Results: The mean Wilkins scores of the PPMS and MMVD groups were 7 ± 1 and 8 ± 1 respectively (P = 0.004). No significant differences were found between the MMVD group and the PPMS group regarding annular circumference (15.5 ± 1.4 cm vs. 15.4 ± 1.6 cm, P = 0.84), annular diameter (36 ± 4 mm vs. 38 ± 5 mm, P = 0.18), and chordae tendinae length directed to the anterior mitral leaflet (AML) (10 ± 2 mm vs. 11 ± 2 mm, P = 0.137). However, anterior vs. posterior mitral leaflet length during systole was significantly lower in the MMVD than in the PPMS group (2.2 ± 0.5 vs. 2.8 ± 0.4, P = 0.02), whereas the AML thickness at the co-aptation point was greater in the MMVD than in the PPMS group (7 ± 1 vs. 5 ± 1 mm, P = 0.0004).

Conclusions: In rheumatic valves, thickening and shortening of the AML are the main factors determining the appearance of mild MR in the presence of dominant pliable MS.

Background: Genetic screening tests for cystic fibrosis (CF), fragile X (FRAX) and spinal muscular atrophy (SMA) have been offered to the entire Arab population of Israel in the last few years. Since 2008, screening for CF is provided free of charge, but for FRAX and SMA the screening is privately funded with partial coverage by complementary health insurance programs.

Objectives: To assess the compliance of Arab couples for genetic screening tests, and the factors that affect their decisions.

Methods: We analyzed compliance for genetic screening tests at the Emek Medical Center Genetic Institute, and in outreach clinics in four Arab villages. We enquired about the reasons individuals gave for deciding not to undergo testing. We also assessed the compliance of these individuals for the triple test (a screening test for Down syndrome).

Results: Of the 167 individuals included in our study, 24 (14%) decided not to be tested at all. Of the 143 (86%) who decided to be tested, 109 were tested for CF only (65%) and 34 (20%) for SMA and FRAX (as well as CF). The compliance rate for the triple test was 87%. Technical reasons, mainly financial issues, were the most significant factor for not undergoing all three tests.

Conclusions: The compliance of the Arab community for genetic testing for SMA and FRAX is extremely low. We believe that this low utilization of screening is due to economic reasons, especially when a complementary health plan has not been acquired, and largely reflects the perception that these tests are less important since they are privately funded.
 

Background: Fatigue is a common complaint in primary care and has a broad differential diagnosis, making the approach complex and often ineffective.

Objectives: To follow the course of adults without a significant known background disease who complain of fatigue for the first time, and to characterize the family physician’s approach.

Methods: The study population comprised a random sample of 299 patients aged 18–45 who presented with fatigue as a first-time single complaint to their family physician. Excluded were patients with chronic diseases or states that may include signs of fatigue. We analyzed the index encounter data, the diagnostic and laboratory tests, the medications prescribed and the one year clinical outcome.

Results: Seventy percent were women, average age 30.5 years, and 69% had no known co-morbidities; 57% of the patients were physically examined at the first visit and most (78.6%) were sent for laboratory analysis. Five percent of laboratory tests were positive. Eighty patients (26.8%) were given a specific diagnosis, with the leading diagnoses being anemia and infectious diseases; 18.7% were given sick leave at the first visit. Fatigue was more common in early summer.

Conclusions: The majority of young healthy patients complaining of fatigue are not diagnosed with an organic physiological disorder. Many of the study patients were sent for laboratory tests but in most cases these tests were not contributory to the diagnosis or management. It seems likely that the most efficient strategy would be watchful follow-up with a minimum of testing.

Background: Patient protection requires the provision of informed consent for participation in medical research. The MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR) is frequently used for screening the capacity of research subjects to consent to participate in research.

Objectives: To evaluate the utility of the Hebrew translation of the MacCAT-CR for the assessment of capacity of patients with chronic schizophrenia to provide informed consent to participate in clinical trials.

Methods: We evaluated the translated MacCAT-CR by comparing the capacity of patients with chronic schizophrenia to provide informed consent to participate in clinical trials. The following standardized neurocognitive assessment tools were used: Addenbrooke’s Cognitive Examination (ACE) and Frontal Assessment Battery (FAB), as well as the attending doctor’s assessment.

Results: Twenty-one patients participated. Mean MacCAT-CR score was12 ¡À 10.57 (range 0¨C32), mean FAB score was 9.9 ¡À 4.77 (range 1¨C18), mean ACE was 59.14 ¡À 16.6 (range 27¨C86) and mean doctor’s assessment was 5.24 ¡À 1.18 (range 3¨C7).

Conclusions: The Hebrew-version of the MacCAT-CR helped identify patients with the capacity to provide informed consent for participation in research. Patients with FAB scores ¡Ý 12 tended to score higher on the Hebrew-version of the MacCAT-CR, thus confirming the utility of the Hebrew version of the MacCAT-CR. During the screening process for clinical trials it may be practical to administer the concise FAB questionnaire, and then administer the MacCAT-CR only to those who scored ¡Ý 12 on the FAB.

Background: The prognostic value of P-wave duration has been previously evaluated by signal-averaged ECG (SAECG) in patients with various arrhythmias not associated with acute myocardial infarction (AMI).

Objectives: To investigate the clinical correlates and prognostic value of P-wave duration in patients with ST elevation AMI (STEMI).

Methods: The patients (n=89) were evaluated on the first, second and third day after admission, as well as one week and one month post-AMI. Survival was determined 2 years after the index STEMI.

Results: In comparison with the upper normal range of P-wave duration (< 120 msec), the P-wave duration in STEMI patients was significantly increased on the first day (135.31 ¡À 29.29 msec, P < 0.001), up to day 7 (127.17 ¡À 30.02 msec, P = 0.0455). The most prominent differences were observed in patients with left ventricular ejection fraction (LVEF) ¡Ü 40% (155.47 ¡À 33.8 msec), compared to LVEF > 40% (128.79 ¡À 28 msec) (P = 0.001). P-wave duration above 120 msec was significantly correlated with increased complication rate namely, sustained ventricular tachyarrhythmia (36%), congestive heart failure (41%), atrial fibrillation (11%), recurrent angina (14%), and re-infarction (8%) (P = 0.012, odds ratio 4.267, 95% confidence interval 1.37¨C13.32). P-wave duration of 126 msec on the day of admission was found to have the highest predictive value for in-hospital complications including LVEF < 40% (area under the curve 0.741, P < 0.001).  However, we did not find a significant correlation between P-wave duration and mortality after multivariate analysis.

Conclusions: P-wave duration as evaluated by SAECG correlates negatively with LVEF post- STEMI, and P-wave duration above 126 msec can be utilized as a non-invasive predictor of in-hospital complications and low LVEF following STEMI.
