Erectile dysfunction is associated with severe retinopathy in diabetic men.

OBJECTIVE: Erectile dysfunction (ED) and retinopathy are prevalent in diabetic men. However, the association between ED and diabetic retinopathy (DR) with relation to DR severity levels has never been studied. MATERIALS AND METHODS: For this cross-sectional study, data were obtained prospectively at the retina clinic of a tertiary medical center. The study group included men with proliferative diabetic retinopathy (PDR) or with severe nonproliferative diabetic retinopathy (NPDR). The control group included diabetic men without retinopathy or with mild NPDR. All men had type 2 diabetes mellitus. All men filled in the Sexual Health Inventory for Males questionnaire (SHIM) to detect significant ED. Significant ED was defined as SHIM questionnaire score <17. RESULTS: The cohort included 102 diabetic men: 64 (62.7%) men in the study group and 38 (37.3%) men in the control group. Mean age for the entire cohort was 64.0 ± 8.2 years, and mean diabetes duration was 14.5 ± 8.9 years. Mean SHIM score for the entire cohort was 11.4 ± 6.5, and 75 (73.5%) men had significant ED. Men in the study group had higher prevalence of significant ED compared with men in the control group (87.5% vs 50.0%; P <.0001), as well as lower mean SHIM questionnaire scores (9.5 ± 5.4 vs 14.7 ± 6.9; P <.0001). Binary logistic regression analysis and linear regression analysis showed that significant ED and SHIM scores, respectively, were associated with DR severity (P = .001 for both), independent of age, diabetes duration, ischemic heart disease, cerebrovascular disease, hypertension, hyperlipidemia, and smoking. CONCLUSIONS: Significant ED is associated with DR severity independent of age, diabetes duration, macrovascular comorbidities, and cardiovascular risk factors.

C-reactive protein velocity following antibiotics in patients with chronic obstructive pulmonary disease exacerbation and community acquired pneumonia.

INTRODUCTION: Distinguishing community acquired pneumonia (CAP) from chronic obstructive pulmonary disease (COPD) exacerbation is a challenging task, since fever, productive cough, dyspnea, and leukocytosis are all common features of both conditions. Moreover, chest X-ray might not be sensitive enough. It is therefore quite common for physicians to prescribe unnecessary antibiotics for COPD exacerbation, leading to resistant bacteria and other related adverse affects. AIM: To study whether CRP levels upon admission and the delta in CRP levels following initiation of antibacterial treatment, could provide an efficient tool for distinguishing CAP from COPD exacerbation. METHODS: The study group included 36 COPD exacerbation and 49 CAP patients, admitted to a single Internal Medicine department during the years 2004-2006. All patients were treated with cephalosporins and macrolides upon admission. RESULTS: CRP levels upon admission were significantly higher among CAP patients than among COPD exacerbation patients (111.5+/-104.4 vs. 34.9+/-28.6 mg/l, p<0.0001). CRP levels on the second day of hospitalization, following antibiotic administration to all patients, made a sharp incline in 36.7% of CAP patients compared to only 5.9% of COPD exacerbation patients (p=0.005), and remained unchanged in 61.8% of COPD patients compared to 16.3% of CAP patients (p=0.0006). CONCLUSIONS: CRP levels upon admission and the delta in CRP levels following initiation of antibacterial treatment could provide an efficient tool for distinguishing CAP from COPD exacerbation.

Drug-induced torsades de pointes in patients aged 80 years or more.

OBJECTIVE: We studied all English-written peer-reviewed reports on drug-induced torsades de pointes (TdP) in patients aged 80 years or more in order to characterize the clinical circumstances leading to this serious complication. METHODS: Our literature search yielded 24 reports on 25 patients aged 80-95 years with drug-induced TdP. We systematically reviewed each report and recorded the non-modifiable risk factors for drug-induced TdP (i.e., female sex and structural heart disease) as well as preventable clinical circumstances, which might have been associated with drug-induced TdP. RESULTS: The most prevalent risk factors for drug-induced TdP were non-modifiable risk factors: 22 (88%) patients were female patients and 19 (76%) patients had structural heart disease. Overall, 16 (64%) patients were female patients with structural heart disease. The literature did not report any elderly male patients without structural heart disease. Among the preventable clinical circumstances, which might have been associated with drug-induced TdP, the most prevalent were: administrating QT prolonging agents despite long QT interval (n=11; 44%) and co-administration of two or more QT prolonging agents (n=9; 36%). The most prevalent QT prolonging agents found to trigger TdP were macrolides and quinolones (n=9; 36%). All but three patients had at least one or more preventable clinical circumstances, which might have been associated with drug-induced TdP. CONCLUSION: Physicians should be more aware of the risk for drug-induced TdP in patients aged 80 years or more while administrating QT prolonging agents despite long QT interval and co- administrating two or more QT prolonging agents, specifically in elderly female patients with structural heart disease.
