Background: QT segment prolongation is a high risk factor for fatal arrhythmias. Several studies have indicated a possible relation between low testosterone levels and QT interval prolongation. 

Objectives: To compare the QT interval length in elderly patients with prostate carcinoma who were on anti-testosterone treatment and those who were not.

Methods: We screened the electrocardiograms (ECGs) of 100 prostate cancer patients divided into two groups: 50 patients on anti-testosterone drug treatment and 50 patients not. QT interval length was measured according to the accepted methods.

Results: The mean QTc 12 leads in the entire group was 0.45 ± 0.04 sec, which is close to the upper limit. Mean QTc was actually longer in the control group and there was no QTc difference between the groups after adjustment for possible confounders. Prolonged QTc 12-lead ECG (48% in treated and 54% in non-treated) and lead L2 QT interval (50% in treated and 56% in non-treated) did not differ significantly between the groups. The analysis of QTc 12-lead ECG indicated no significant effects of anti-testosterone drug treatment. Only the use of furosemide was associated with QT prolongation. 

Conclusions: The results of this preliminary study do not support our initial concern of an alarmingly prolonged QT interval in the anti-testosterone treated group. However, further prospectively designed studies are needed. In the meanwhile we call for a close follow-up of the QT interval length in patients receiving anti-testosterone treatment.

Background: Several trials support the trans-radial route of percutaneous coronary intervention (PCI) since it reduces access site vascular complications and bleeding. 

Objectives: To examine the effects of trans-radial interventions (TRI) on clinical outcomes in a 'real world' cohort of patients undergoing PCI.

Methods: We analyzed 4873 consecutive patients who underwent PCI at a tertiary center and identified 373 patients who underwent TRI. Patients (radial vs. femoral) were compared using a propensity score analysis to best match between groups. Outcome parameters included total mortality, myocardial infarction (MI), repeat target vessel revascularization (TVR) rates, length of hospitalization and ∆Ht/Hb/creatinine values during hospitalization. These were evaluated at 6 months and 1 to 3 years after PCI.

Results: The rates of major adverse cardiovascular event (MACE) and its constituents were similar in the trans-radial vs. trans-femoral groups at all time intervals: 6.7% vs. 5.5% at 6 months, 10.3% vs. 10% at 1 year, 15.7% vs. 15% at 2 years, 15.7% vs. 16% at 3 years, respectively (P = 0.6). The length of hospitalization was shorter in the TRI group (2.87 days ± 2.04 vs. 3.3 days ± 3.12, P = 0.023). We did not find significant differences between the groups in the mean ∆Ht/Hb/creatinine values during the hospitalization course.

Conclusions: In a 'real-world' setting of PCI, the TRI route of PCI is as safe and efficient as the femoral approach. TRI is associated with shorter duration of hospitalization.

Background: The number of patients awaiting organ transplantation continues to exceed the number of available organs. 

Objectives: To document changes in the demographic characteristics of brain-dead, heart-beating organ donors over the past 10 years which may impact on organ utilization. 

Methods: Data were extracted from the Israel Transplant Registry and the Donor Action database for the 10 year period 2004–2013, inclusive. 

Results: The median age of the donors increased from 44 (range 3–73 years) to 53.5 years (range 1–79 years) (P < 0.001). There was a significant increase in the median age of donors of kidney (33 to 51 years, P < 0.001), liver (41 to 53 years, P < 0.001) and lung (40 to 49.5 years, P < 0.001). The number of donors dying from trauma decreased (34.5% to 20%, P < 0.001), while those with anoxic brain damage increased (14.5% to 25%, P < 0.001). The percent of male donors decreased over the study period, from 63% to 53%. An increase was noted in the mean number of organs transplanted per donor, from 3.29 to 3.82 per donor, due mainly to a significant increase in the utilization of lungs (31.5% to 51.3%, P < 0.001) and livers (76.3% to 82.4%, P < 0.001) while heart utilization decreased significantly since 2006 (40.9% to 17.5%, P < 0.001). 

Conclusion: Trends in the heart-beating, brain-dead organ donor pool in Israel over the past 10 years reveal significant changes in demographic characteristics which in the future will impact on the number of organs available for transplantation.

Fungal diseases affect a large proportion of the population, ranging in severity from mild superficial infections to life-threatening invasive diseases. Estimates of disease burden are needed to inform public health policies. We estimated the incidence of fungal diseases in Israel based on published surveillance data and risk-based calculations using previously established models. Deaths associated with fungal diseases were estimated from local surveillance data (candidemia) and published reports (invasive aspergillosis). Candidemia was estimated in 649 persons/year and invasive aspergillosis in 254 persons/year; the associated mortality was 2.75 and 0.96 per 100,000 population/year, respectively. Recurrent Candida vulvovaginitis occurs in 130,440 women annually. National incidence rates of cryptococcosis, pneumocystis pneumonia and mucormycosis could not be reliably estimated. Single-center data-derived estimates yielded 24, 26 and 20 cases/year, respectively. Allergic bronchopulmonary aspergillosis, asthma with fungal sensitization and allergic fungal sinusitis affect 8297 (range 2323–11,615), 14,372 (14,372–17,965) and 39,922 (15,969–183,643) persons, respectively. In Israel, candidemia and invasive aspergillosis rank high among infection-related causes of mortality. Allergic fungal diseases cause chronic or recurrent symptoms in a large population and may contribute to asthma-related hospitalization and death. These general estimates should serve as a primer for future efforts to study fungal epidemiology.

Abstract

Background: A single self-rated health (SRH) assessment is associated with clinical outcome and mortality, but the biological process linking SRH with immune status remains incompletely understood.

Objectives: To examine the association between SRH and inflammation in apparently healthy individuals.

Methods: Our analysis included 13,773 apparently healthy individuals attending the Tel Aviv Sourasky Medical Center for periodic health examinations. Estimated marginal means of the inflammation-sensitive biomarkers [i.e., highly sensitive C-reactive protein (hs-CRP) and fibrinogen] for the different SRH groups were calculated and adjusted for multiple potential confounders including risk factors, health behavior, socioeconomic status, and coexistent depression.

Results: The group with the lowest SRH had a significantly higher atherothrombotic profile and significantly higher concentrations of all inflammation-sensitive biomarkers in both genders. Hs-CRP was found to differ significantly between SRH groups in both genders even after gradual adjustments for all potential confounders. Fibrinogen differs significantly according to SRH in males only, with low absolute value differences.

Conclusions: A valid association exists for apparently healthy individuals of both genders between inflammation-sensitive biomarker levels and SRH categories, especially when comparing levels of hs-CRP. Our findings underscore the importance of assessing SRH and treating it like other markers of poor health.

Background: A new device, the CCS-30 Contour Transtar, was recently launched for the treatment of obstructed defecation syndrome (ODS).

Objectives: To evaluate the efficacy of the Contour Transtar in resection of true rectal prolapse in relation to age and concomitant urogynecologic procedures.

Methods: During a 50 (median) month period 15 women with rectal prolapse of ≥ 5 cm and complaints of obstructed defecation underwent perineal resection of rectal prolapse with the Contour Transtar.

Results: In 3 of the 15 patients (20%) rectal prolapse recurred. Amelioration of ODS symptoms and improved continence were noted in 82% and 75%, respectively, following surgery.

Conclusions: The Contour Transtar procedure for full-thickness rectal prolapse is a safe and promising procedure and is likely suitable for elderly poor risk patients.

Abstract

Background: The mass influx of immigrants from tuberculosis-endemic countries into Israel was followed by a considerable increase in the incidence of tuberculosis (TB). All contacts of active TB patients are obliged to be screened by tuberculin skin tests (TST) and, if found positive, prophylactic treatment is considered.

Objectives: To assess the utility of interferon-gamma (IFNγ)-release assay with a prolonged follow-up in preventing unnecessary anti-TB therapy in individuals with suspected false positive results.

Methods: Between 2008 and 2012 the QuantiFERON TB gold-in-tube test (QFT-G) was performed in 278 sequential individuals who were mostly TST-positive and/or were in contact with an active TB patient. In all, whole blood was examined by the IFNγ-release assay. We correlated the TST diameter with the QFT-G assay and followed those patients with a negative assay.

Results: The QFT-G test was positive in only 72 (42%) of all 171 TST-positive individuals. There was no correlation between the diameter of TST and QFT-G positivity. Follow-up over 5 years was available in 128 (62%) of all QFT-G-negative individuals. All remained well and none developed active TB.

Conclusions: A negative QFT-G test may obviate the need for anti-TB therapy in more than half of those with a positive TST.

Abstract

Background: Iatrogenic ureteral injury may be seen following abdominopelvic surgeries. While ureteral injuries identified during surgery should be immediately and surgically repaired, those that are postoperatively diagnosed may be treated non-surgically by draining the ipsilateral kidney. Data regarding the outcome of this approach are still missing.

Objectives: To evaluate the success rates of non-surgical management of ureteral injuries diagnosed following abdominopelvic surgeries.

Methods: We retrospectively reviewed the files of all patients treated for iatrogenic ureteral injuries diagnosed following abdominopelvic surgeries. Patients' ipsilateral kidney was percutaneously drained following diagnosis of injury by either nephrostomy tube (NT)/nephro-ureteral stent (NUS) or double-J stent (DJS) inserted retrogradely. The tube was left in place until a pyelogram confirmed healing or a conservative approach was abandoned due to failure.

Results: Twenty-nine patients were identified as having ureteral injury following abdominopelvic surgery. Median time from injury to renal drainage was 9 days, interquartile range (IQR) 4–17 days. Seven cases (24%) had surgical repair. Among the other 22 patients, in 2 oncology patients the conservative approach was maintained although renal drainage failed to resolve the injury. In the remaining 20, median drainage length was 60 days (IQR 43.5–85). Calculated overall success rates following renal drainage was 69% (18/29), and with NS approached 78.5%.

Conclusions: Ureteral injuries diagnosed following abdominopelvic surgeries can be treated conservatively. Ipsilateral renal drainage should be the first line of treatment before surgical repair, and NUS may be the preferred drainage to obtain spontaneous ureteral healing.
