An atypical radiographic appearance of a cardiac myxoma: case report and review of the literature.

Cardiac myxomas are the most common primary cardiac tumours in adults. They usually present as a solitary, solid mass in the left atrium. Their most common radiographic appearance is that of a hypodense lesion on computed tomography (CT) and inhomogeneous lesion (hypo to isointense on T1 sequences and hyperintense on T2 sequences) on magnetic resonance (MR) with some contrast enhancement.

Clinical presentation of Bacillus Calmette-Guérin infections in patients with immunodeficiency syndromes.

Nine children with immunodeficiency syndromes who developed persistent or disseminated Bacillus Calmette-Guérin (BCG) infections after BCG vaccination at birth were observed in Santiago, Chile, over a period of 10 years. This represents a risk for persistent or disseminated BCG infections of 3.4/1,000,000 vaccinated newborns.

Dimethyl sulfoxide therapy in bronchiolitis.

The action of a medicinal spray that contains anti-inflammatory and bacterio-static drugs integrated with the penetrating and potentiating agent DMSO has been evaluated clinically in 60 infants with acute respiratory obstruction. A dose of 2 ml of this spray is applied in the posterior pharynx and the tonsil region; 1 to 4 applications are made, according to the clinical evolution of the case. Two groups were chosen at random; 60 patients were paired off, and one of each pair received the treatment with DMSO spray.
