Venous thromboembolism (VTE) is a common potentially life-threatening complication in acutely ill medical patients; over 70 % of the fatal episodes of pulmonary embolism during hospitalization occur in non-surgical patients. In the absence of thromboprophylaxis, the incidence of venographically detected deep vein thrombosis is about 15 % in medical patients. Several trials and meta-analyses have clearly demonstrated the prophylactic role of unfractionated heparin, low molecular weight heparin and fondaparinux. ⋯ The optimal duration of thromboprophylaxis in medical patients is still a matter of debate; currently, extended prophylaxis after discharge is not recommended, but it may be required for subgroup of patients with persistently high VTE risk and a negligible risk of bleeding. Based on the results of recent studies, the new oral anticoagulants appear to have a very limited role, if any. However, a better risk stratification of patients who have a persistently increased risk of VTE is warranted to improve the risk to benefit profile of any anticoagulant drug to be used in this setting.

Clostridium difficile-associated disease (CDAD) is a growing health care problem. Elderly patients with multiple comorbidities and repeated hospitalization are at high risk for developing the disease. Few data are available on epidemiology of CDAD in Italy and no studies have focused on CDAD burden in internal medicine wards. ⋯ A high proportion of CDAD patients had several comorbidities and had been treated with more than one antibiotic. The incidence is among the highest previously reported, this may be due to the characteristics of patients admitted to internal medicine wards and to the wards per se. We conclude that efforts are needed to reduce CDAD's burden in this setting, paying attention to logistics, patients care and antibiotic use.

The impact of chronic kidney disease (CKD) on the outcome of acute pulmonary embolism (PE) is uncertain. We aimed to evaluate the effect of renal dysfunction (defined by ICD-9-CM codification) on in-hospital mortality for PE. We considered all cases of PE (first event) recorded in the database of hospital admissions for the Emilia-Romagna region, Italy, from 1999 to 2009. ⋯ In-hospital mortality for PE was not different in patients without renal dysfunction, with CKD, or ESRD (23.6 vs. 24 vs. 18 % p = ns). In-hospital mortality for PE was independently associated with age (OR 1.045, 95 % CI 1.042-1.048, p < 0.001), female sex (OR 1.322, 95 % CI 1.242-1.406, p < 0.001), hypertension (OR 1.096, 95 % CI 1.019-1.178, p = 0.013), diabetes mellitus (OR 1.120, 95 % CI 1.001-1.253, p = 0.049), dementia (OR 1.171, 95 % CI 1.020-1.346, p = 0.025), peripheral vascular disease (OR 1.349, 95 % CI 1.057-1.720, p = 0.016) and malignancy (OR 1.065, 95 % CI 1.016-1.116, p = 0.008). Age and comorbidity are associated with in-hospital mortality for PE, whereas CKD does not appear to be an independent predictor of adverse outcomes in patients hospitalized for PE.
