Single-dose oritavancin versus 7-10 days of vancomycin in the treatment of gram-positive acute bacterial skin and skin structure infections: the SOLO II noninferiority study.

Background: Oritavancin is a lipoglycopeptide antibiotic with rapid bactericidal activity against gram-positive bacteria. Its concentration-dependent activity and long half-life allow for single-dose treatment.

Methods: In a randomized, double-blind trial, adults with acute bacterial skin and skin structure infections (ABSSSIs) received either a single intravenous 1200-mg dose of oritavancin or 7-10 days of twice-daily vancomycin.

[Calcification and ossification of lungs].

The different types of lung calcification and ossification including idiopathic and developing after various diseases are in the article. We have described rare lung pathology - pulmonary alveolar microlithiasis. We have drawn attention to the possible mechanisms of lung calcification and ossification development.

[Cardiopathies in children].

Cardiomyopathies in children are rather rare, but extremely severe disorders that are little known in practical healthcare. Many of them are a cause of sudden death and they are familial. By using their findings and the data available in the literature, the authors describe the etiology, pathogenesis, morphology, and clinical presentation of dilated, hypertrophic, arhythmogenic right ventricular, histiocytoid cardiomyopathies, as well as the non-compact myocardium, and a type of cardiac connective tissue dysplasia.

Effect of prenatal lead exposure on superoxide dismutase activity in the brain and liver of rat fetuses.

Prenatal lead exposure had a damaging effect on Cu/Zn superoxide dismutase activity in the brain and liver of rat fetuses (20 days of gestation). The decrease in Cu/Zn superoxide dismutase activity in the brain and liver of treated fetuses reflects activation of free radical processes and impairment of the antioxidant defense system during prenatal lead exposure.
