Two different forms of dyssegmental dysplasia, mild and severe, can be distinguished on clinical, radiographic and chondro-osseous morphologic grounds. The milder Rolland-Desbuquois type is frequently characterised by survival beyond the newborn period. The lethal Silverman-Handmaker type has distinctive and more severe findings. In this paper, a rare case of the Rolland-Desbuquois type is presented. The case is unusual because although it was the milder form, the child died on the 10th day of life.

Pertussis, or whooping cough, is a highly infectious respiratory disease, endemic all over the world, caused by bacteria Bordetella pertussis. The authors describe the case of a 36 day old infant, brought to the emergency room due to respiratory distress and cyanosing cough, admitted with suspected pertussis infection complicated by bacterial pneumonia, having begun large spectrum antibiotics. Labs showed hyperleukocytosis and thrombocytosis. She was transferred to an Intensive Care Unit because of a worsened state, dying 20 hours after admission with pulmonary hypertension and haemorrhage. Pertussis was diagnosed by PCR. Over the last few years, there has been an increase in the number of cases of pertussis. Adolescents and adults have become an under-recognized but significant source of infection, particularly to small unvaccinated infants. The authors underline the importance of recognizing pertussis, so that even in its atypical presentation, one can suspect, treat, report and prevent a disease that is not, and is not expected to be, eradicated any time soon. New vaccination strategies are necessary, to avoid this disease, which can be fatal to the most vulnerable.
