Case ReportsSpuriously elevated automated platelet count in severe burns--a report of two cases.
Increasing use of automated analyzers in the hematology laboratory has resulted in enhanced accuracy of results. However, operators of automated analyzers and the end users utilizing the automated data need to be aware of factitious results which might be reported at times by these instruments. Case summaries of two patients with severe burns showing spuriously elevated automated platelet count are presented here.

Utility of dystrophin and utrophin staining in childhood muscular dystrophy.
To determine the utility of dystrophin and utrophin staining in the differential diagnosis of childhood muscular dystrophy. Fifty muscle biopsies of histologically confirmed cases of childhood muscular dystrophy, below 16 years of age, were stained immunohistochemically for dystrophin and utrophin. All the 30 muscle biopsies of patients with Duchenne muscular dystrophy (DMD) showed all or majority of muscle fibers deficient for dystrophin and positive for utrophin. ⋯ All the muscle biopsies of patients with other childhood onset muscular dystrophies were positive for dystrophin and negative for utrophin. This study shows that dystrophin staining differentiates DMD and DMD carriers from other childhood muscular dystrophies and utrophin staining is of no added value. Utrophin up-regulation may compensate for structural deficiency in dystrophic muscle.
