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. 

 

Objectives: To assess the nature of joint problems encountered in a geriatric inpatient population and evaluate the contribution of a rheumatologist.

Methods: We reviewed the rheumatology consultations that were conducted in a geriatric medical center over a 10 year period.

Results: A total of 474 consultations were held; most of these patients (86%) were hospitalized in the acute geriatric departments, 10% in the rehabilitation ward and 4% in the long-term care wards. Some patients were seen more than once. The rheumatologic joint problem was the main reason for hospitalization in 53% of these patients. Monoarthritis was the most frequent complaint (50%), followed by pauci-articular arthritis (two to five joints) in 30% of patients. Arthrocentesis, diagnostic and therapeutic, was performed in 225 patients, most of them on knee joints (81%). The most frequent diagnosis was osteoarthritis with acute exacerbation (28%), followed by gout (18%), pseudo-gout (9%) and rheumatoid arthritis (9%). In 86 cases (18%) the diagnosis was a non-specific rheumatologic problem: arthralgia, non-specific generalized pain, or fibromyalgia.

Conclusions: Prompt and appropriate evaluation, as well as arthrocentesis and treatment initiation, including local injections, were made possible by the presence of an in-house rheumatologist. 

Background: Pulmonary tuberculosis continues to be a major cause of mortality, particularly in developing countries. Despite modern anti-TB[1] treatment, the elderly and immigrants from TB-endemic countries are at risk. Multidrug resistance has yet to be resolved..

Objectives: To determine the mortality rate and predictors of mortality among patients hospitalized with TB in Israel.

Methods: We evaluated the medical records of 461 patients with active pulmonary TB who were hospitalized in the department of respiratory care during the 5 year period 2000–2004. Data included demographic, clinical, laboratory and radiological findings, drug resistance as well as adverse reactions to anti-TB treatment.

Results:| Three main ethno-geographic groups were observed: 253 patients from the former USSR, 130 from Ethiopia, and 54 of Israeli origin (as well as 24 residents of other countries). Of the 461 patients 65 patients (13%) died in hospital. The factors that were best predictors of mortality were older age, ischemic heart disease, cachexia, prior corticosteroid treatment, hypoalbuminemia and pleural effusion (P < 0.005 for all). The ethno-geographic factor and the presence of multidrug-resistant bacteria had no significant effect on mortality in our study group.

Conclusions: The mortality rate in our study was relatively low, and there was no significant difference between the three ethno-geographic groups.
