Radiological abnormalities of the ribs are reported in 5 newborn infants with myotonic dystrophy. In all 5, the ribs appeared very thin, in contrast to the normal appearance of the rest of the skeleton. This slenderness, which is important for diagnosis and prognosis, seems to be caused by hypotonia of the intercostal muscles. However, it is not pathognomonic of myotonic dystropy, for it can be observed in other myopathies.
By examining the endobronchial brushings from 65 infants and children with interstitial pneumonia--characterized by a severe hypoxia and diffuse lung infiltrates--we have detected the cysts of pneumocystis carinii in 17 of 21 subsequently confirmed cases. The rapid diagnosis and subsequent specific treatment have allowed the recovery of 18 of these children. The particular significance of this article is the youth of the patients, whose ages ranged from 4 months to 15 years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
