Statin-Induced Immune-Mediated Necrotizing Myopathy with Anti-HMGCR Antibody / 대한신경근육질환학회지

Anti-3-hydroxy-3-methylglutaryl coenzyme A reductase (anti-HMGCR) antibody related immune-mediated necrotizing myopathy (IMNM) are usually associated with statin use. The disease has features of persistent muscle weakness and creatine kinase (CK) elevation after statin discontinuation. This report describes a 65-year-old female taking atorvastatin, presenting with both proximal lower extremity weakness. IMNM feature were detected on muscle biopsy and high anti-HMGCR autoantibody titer on enzyme-linked immunosorbent assay (ELISA). This patient was treated with corticosteroid. Muscle weakness and CK are improved after immunosuppressive therapy.

The Differences in Obesity Rates According to Status of Co-Residence with Their Parents in Korean Adolescents: The Implication of the Gender of Single Parent Living with Adolescents

BACKGROUND: Many studies have reported that adolescents living with single parent have a high risk of obesity. However, those studies did not explore the implication of the gender of single parent living with adolescents. This study investigated the differences in obesity rates according to status of co-residence with their parents in Korean adolescents. The family living with single parent was classified into the family living with single father and the family living with single mother. METHODS: This cross-sectional study involved 59,602 adolescents who participated in the 2017 Korea Youth Risk Behavior Web-based Survey. The data on height, weight, status of co-residence with parents, and the other variables were obtained through online questionnaires. RESULTS: In male adolescents, the family living with single mother was related to a high proportion of obesity (odds ratio [OR] 1.24, 95% confidence interval [CI] 1.09–1.40) and overweight (OR 1.17, 95% CI 1.03–1.34). However, in female adolescents, the family living with single father was related to a high proportion of obesity (OR 1.49, 95% CI 1.23–1.82). In addition, female adolescents living with neither parent were more likely to be obese (OR 1.47, 95% CI 1.13–1.91) and overweight (OR 1.31, 95% CI 1.00–1.70). CONCLUSIONS: This study showed a risk of obesity in adolescents living with single parent differs according to the gender of single parent living with adolescents. Not adolescents living with a same-gender parent, but those living with an opposite-gender parent have a high risk of obesity.

Immunohistochemical study on the expression of calcium binding proteins (calbindin-D28k, calretinin, and parvalbumin) in the cerebellum of the nNOS knock-out(-/-) mice / 대한해부학회지

Nitric Oxide (NO) actively participates in the regulation of neuronal intracellular Ca2+ levels by modulating the activity of various channels and receptors. To test the possibility that modulation of Ca2+ buffer protein expression level by NO participates in this regulatory effect, we examined expression of calbindin-D28k, calretinin, and parvalbumin in the cerebellum of neuronal NO synthase knock-out (nNOS(-/-)) mice using immunohistochemistry. We observed that in the cerebellar cortex of the nNOS(-/-) mice, expression of calbindin-D28k and parvalbumin were significantly increased while expression of calretinin was significantly decreased. These results suggest another mechanism by which NO can participate in the regulation of Ca2+ homeostasis.
