Evaluation of autonomic modulation of lung function and heart rate in children with cystic fibrosis.

The autonomic nervous system (ANS) plays an important role in modulating bronchial smooth muscle contractility, which is altered in cystic fibrosis (CF). A convenient approach to probe ANS regulation is the quantitative analysis of heart rate variability (HRV). The purpose of this study was to evaluate ANS regulation in children with CF and to investigate the influence of colonization by Pseudonomas aeruginosa via assessment of HRV in colonized CF (CCF) children and noncolonized CF (NCCF) children.

Tumoral chromoblastomycosis: a rare manifestation with typical complementary exams.

Chromoblastomycosis is a chronic subcutaneous fungal infection caused by traumatic implantation of dematiaceous fungi in the skin. The clinical presentation is usually a verrucous plaque lesion and the diagnosis is confirmed by the visualization of muriform bodies at direct examination or at the histologic study. This report describes a rare case of tumoral chromoblastomycosis confirmed by histologic study and whose agent was identified by culture and micromorphology.
