Acute acalculous cholecystitis (AAC) in association with acute Epstein-Barr virus (EBV) infection has rarely been described in childhood. In the literature, there are only four reported pediatric cases of AAC associated with isolated primary EBV infection. We present two cases (one new, one retrospectively reviewed) of children with Gilbert's syndrome (GS) who presented with AAC during the course of primary EBV infection. Antibiotics were not used and AAC subsided gradually as the infection regressed. The co-occurrence of GS might have played a contributory role in the pathogenesis of AAC during acute EBV infection.
Valproate monotherapy may cause significant alteration in thyroid profile in children with epilepsy, occurring early in the course of treatment and persisting as long as VPA is initiated. Therefore, it may be useful to measure serum thyroid hormone concentrations routinely in children with epilepsy taking VPA. Further prospective studies are required to determine the mechanisms and risk factors for development of thyroid disturbance in children treated with VPA monotherapy.
The etiology of transient erythroblastopenia of childhood (TEC) remains unknown, although an association with viral infections has been proposed. The authors describe a 3.5-year-old girl with classic TEC concomitantly with human parvovirus B19 (HPV) infection. The infection was evident by detection of HPV genome in the blood and the bone marrow by polymerase chain reaction. Viral genome was no longer detected when the TEC resolved clinically. The patient was immunocompetent and the anemia has not recurred. To the authors' knowledge, this is one of the few documented cases of classic TEC attributable to HPV infection.
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.
