Oral health and dental anxiety in a German practice-based sample.

Objective: Does dental anxiety have an effect on dental and periodontal health?

Methods: Survey data was collected from n = 200 adults (53 % females, average age 49 years) in a cross-sectional study. Dental anxiety was measured with the modified dental anxiety scale (MDAS, score 1-5, the greater the score, the greater the anxiety). Clinical parameters including probing depth (PD), clinical attachment level (CAL), plaque index (SLI), and bleeding on probing (BoP) as well as the DMFT index were recorded and statistically analyzed.

Characterization of hip and knee arthroplasties and factors associated with infection.

Objective: To characterize arthroplasty procedures, calculate the surgical infection rate and identify related risk factors.

Methods: This was a retrospective cohort study. Data on operations performed between 2010 and 2012 were gathered from documental sources and were analyzed with the aid of statistical software, using Fisher's exact test, Student's t test and the nonparametric Mann-Whitney and Wilcoxon tests.

Outbreak of carbapenem-resistant Acinetobacter baumannii producing the OXA-23 enzyme in Curitiba, Brazil.

Carbapenem-resistant Acinetobacter baumannii isolates were obtained from eight patients in two hospitals in Curitiba, Brazil. The isolates were multiresistant, belonged to a single strain, and produced the OXA-23 carbapenemase. Treatment options were limited, although the isolates were susceptible to polymyxin B in vitro.
