[Causes of hospitalization of patients with ongoing varicella in a French children hospital: evolution between 1990 and 2001].
OBJECTIVE
To describe the characteristics of paediatric varicella in patients admitted through the emergency department (ED) of the Armand-Trousseau Children hospital in Paris and the evolution of the causes of admission during the study period.


METHODS
Retrospective longitudinal cohort study from March 1990 to February 2001.


RESULTS
One hundred and eight children were hospitalized for varicella during these 11 years. Sixty per cent were under 2 years of age and all but one were immunocompetent. The first cause of admission was the presence of at least 1 complication (83,3%) classified as: cutaneous (34%), digestive (19,8,%), respiratory (17,6%), neurological (15,3%) and ENT complications (8,8%). Over 11 years, the rate of overall complications remained stable but there was an important increase in varicella cases admitted through the ED mainly due to increase in cutaneous superinfections.


CONCLUSIONS
These data confirm the potential severity of varicella and underline the emerging problem of increasing cutaneous complications. Additional studies are necessary to address this phenomenon and to determine optimal prophylactic measures.
