An apple a day ... chronic glossitis in a 4-year-old boy.

We report a case of chronic glossitis in a 4-year-old boy due to scurvy. The boy showed up in our department with a patchy depapillated tongue. A detailed dietary history revealed an unbalanced diet without any fruit or vegetable. The biological investigations showed a low serum ascorbic acid. The boy was treated by oral ascorbic acid during 15 days. The glossitis improved within one week and serum levels of vitamin C returned to the normal range. In industrial countries, scurvy became a rare disease in healthy children. However, since a few years, cases are reported in children and teenagers with unbalanced diet coming from economically favoured families. These extreme cases are one of the signs of a more general deterioration of dietary habits in paediatric populations in our societies. This emphasizes the importance of effective nutritional education programs aimed towards both parents and children.

Inflammatory bowel disease and hepatitis B and C.

The risk of viral B and C hepatitis has long been considered to be increased in patients with inflammatory bowel disease (IBD). Blood transfusion and surgery have been identified as the two main risk factors, suggesting nosocomial transmission could be involved. However, recent epidemiologic surveys have found that prevalence in IBD patients is similar to or even lower than that in the general population. Part of the explanation of these recent data may lie in the application of protective measures against viral infection (hepatitis B virus [HBV] vaccination and hepatitis C virus [HCV]-free blood transfusions). Sometimes fatal viral reactivations have been reported in patients on immunosuppressive therapy. Two periods can be distinguished: a) during therapy, a rise in viremia associated with a decrease of immune-mediated hepatic lesions; b) after cessation of therapy, an immune rebound with a destruction of virus-infected hepatocytes. For HBV, preemptive strategy consisting of an antiviral analog is efficient in chronic HBs antigen carriers. For HCV, the impact of immunosuppressive drugs on the natural history is unclear. Most studies report improved comfort although no biopsies were performed before and after immunosuppressive treatment. Physicians managing IBD patients should be aware of the need for screening and institute preventive measures against B and C hepatitis.
