The burden of chronic obstructive pulmonary disease in patients hospitalized with heart failure.
Like chronic heart failure, chronic obstructive pulmonary disease (COPD) is an enormous public health problem in industrialized countries. Our aim was to determine the prevalence and clinical impact of COPD among patients hospitalized for heart failure in a community hospital serving a population of 125,000 people. ⋯ COPD is frequent among hospitalized patients with heart failure. Beta-blockers are largely underused, which is probably a major reason for the higher mortality observed in patients with concomitant chronic heart failure and COPD.

Sonographic evaluation of unexplained pleural exudate: a prospective case series.
Thoracic ultrasound may be helpful in differentiating between malignant and tuberculosis-associated pleural exudate. This study aimed to evaluate its utility in patients with unexplained pleural exudate. ⋯ Thoracic ultrasound is a useful bedside method for differentiation of the etiology of pleural exudate. When a complex septal pattern is found, pleural needle biopsy should be the next diagnostic procedure, whereas with less complex pleural sonography findings other methods should be pursued.

Case ReportsVerrucous carcinoma of the tibia arising after chronic osteomyelitis: a case report.
Verrucous carcinoma is an uncommon complication of chronic osteomyelitis. The incidence of fistular carcinomas is reported to be between 0.21% and 3.36%. We present a case of verrucous carcinoma of the tibia arising after 58 years of chronic osteomyelitis. ⋯ We used modern diagnostic investigations (biopsy, computed tomography, angiography, immunoscintigraphy, magnetic resonance tomography) to visualize the extent of the malignant lesion. No metastases were detected. Knee exarticulation was successful in treating the tumor and chronic infection in this case.

Heart rate-corrected QT interval and QT dispersion in patients with pulmonary hypertension.
Heart rate-corrected QT interval (QTc) and QTc dispersion (QTcd) are increased and associated with ventricular arrhythmia and an increase in sudden death in a variety of diseases. This study aimed to examine QTc and QTcd in pulmonary hypertension and assess their relationship with pulmonary arterial pressure. ⋯ In women with pulmonary hypertension, mean QTc and QTcd are positively correlated to mean pulmonary arterial pressure and are significantly increased in patients with severe pulmonary hypertension.
