An autopsy case of 10 months old male infant with typical type II glycogenosis was reported. In addition to routine histopathological and histochemical studies on skeletal muscle biopsy and specimens obtained at autopsy, histochemical analyses of the enzyme activities, electromicroscopic studies on muscle biopsy, and cardiac muscle and liver obtained at autopsy were employed. In our case, His bundle electrogram was performed and histopathologically the shortening and some degenerations were found in the atrioventricular junction, especially in His bundle and central fibrous body.
We report a case of a 15 year old boy with polyarteritis nodosa associated with antineutrophil cytoplasmic antibody (ANCA) against proteinase 3 (PR3). After months of steroid and immunosuppressant therapy, the symptoms subsided and the polyaneurysms almost disappeared. The levels of anti‐PR3 antibody and of cytokines also decreased. The results indicate that ANCA is a good indicator of this disease activity, and may play some pathogenic role in the disease.
Urinary chondroitin sulfates were measured quantitatively and qualitatively in healthy human males ranging from prematurity to 80 years of age. Between 20 and 30 years of age, chondroitin 4-sulfate the predominant urinary component in the young is displaced by chondroitin 6-sulfate. Chondroitin (molecular weight about 20,000) constitutes 21% of the total glycosaminoglycans in premature infants but rapidly decreased to 2.5 % by 4 years of age.
A four‐month‐old male premature infant fed by mother's milk caused symptomatic zinc deficiency (acrodermatitis enteropathica). The prematurity and low zinc concentration in mother's milk were speculated as the main factors of the condition in this patient.
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.
