A positive relationship between patient volume and outcome has been demonstrated for a variety of clinical conditions and procedures, but the evidence is sparse for critically ill patients. ⋯ Our results provide evidence for a relationship between patient volume and outcome in critically ill patients. Besides the total number of patients, diagnostic variability plays an important role. The relationship between volume and outcome seems, however, to be complex and to be influenced by other variables, such as workload of nursing staff.

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.

A food-borne outbreak of Shigella sonnei gastroenteritis, Austria, 2008.
We report on the first foodborne outbreak of Shigella sonnei described in Austria. On July 14 2008, AGES was informed of a cluster of 22 laboratory-confirmed cases of infection with S. sonnei restricted to public health district X in the province of Salzburg. All cases had attended a youth-group trip to a small village in the province of Tyrol from July 7 to July 9. ⋯ Among the 42cases, 34 could be explained by consumption of salad. The landlady of the hostel, who prepared the salad with bare hands, was a carrier and was assumed to be the source of contamination of the salad. Without proper epidemiological analytical investigation of this shigellosis outbreak, its association with food consumption would not have been identified.

Atrial fibrillation is an independent determinant of increased NT-proBNP levels in outpatients with signs and symptoms of heart failure.
N-terminal pro-B-type natriuretic peptide (NT-proBNP) is increasingly used in the diagnosis and prognostic assessment of heart failure; however, the possible influence of atrial fibrillation on BNP is still a matter of controversy. We assessed the influence of atrial fibrillation on NT-proBNP levels in outpatients with signs and symptoms of heart failure. ⋯ Atrial fibrillation is an independent determinant of increased NT-proBNP levels. This association should be taken into account when NT-proBNP levels are used in the diagnosis of heart failure in patients with atrial fibrillation.

Clinical TrialTreatment of inappropriate sinus tachycardia with ivabradine.
Inappropriate sinus tachycardia is most often treated with beta-blockers; in resistant cases, nonpharmacologic treatment has been attempted. Recent case reports have shown a favorable response to ivabradine in some patients. ⋯ The results of our study show that patients with inappropriate sinus tachycardia can be successfully treated with ivabradine.
