Sudden cardiac death in childhood hypertrophic cardiomyopathy.

The most prevalent cause of mortality in children with hypertrophic cardiomyopathy (HCM) is sudden cardiac death (SCD), which happens more frequently than in adult patients. Risk stratification tactics have generally been drawn from adult practice, however emerging data has revealed significant disparities between children and adult cohorts, implying the need for pediatric-specific risk stratification methodologies. We conducted an all-language literature search on Medline, Cochrane, Embase, and Google Scholar until October 2021.

Clinical variability of facioscapulohumeral muscular dystrophy in Russia.

One hundred forty-two patients (66 men and 76 women) from 20 autosomal-dominant pedigrees and 3 families including 5 "sporadic" cases were examined. A great similarity of clinical manifestations among those affected was noted. Clinical variability of phenotypes reflecting various phases of the disease and different expressions of the mutant gene were always within the limits of the identical final phenotype of the disease, namely the facio-scapulo-humero-peroneal-femoro (posterior group of the muscles)-gluteal (gluteus maximus).

Experimental thyrotoxic myopathy: radioautography of protein synthesis in skeletal muscle and motor neurons of spinal cord.

The total protein synthesis was studied in skeletal muscle and spinal motor neurons in experimental thyrotoxic myopathy (TM) mice by using radioautography with 3H-methionine. A significant increase of mean specific radioactivity was found in motor neurons of mice with TM. No statistical differences were established in the level of 3H-methionine inclusions into muscle fibre proteins of experimental and control animals.

Histopathology of experimental vaginal candidosis in immunosuppressed mice.

The histopathology of vaginal candidosis was studied in cyclophosphamide (CY)-immunosuppressed mice. In severely leucopenic animals acutely treated with high doses of CY the fungal inoculation resulted in a massive invasion of the pathogen, which penetrated the whole thickness of vaginal wall and was able to spread further into the surrounding tissues. In some animals, a haematogenous dissemination of the infection was detected.

Histopathology of human vaginal candidosis.

Histological changes of vaginal and ectocervical mucosa in women of reproductive age suffering from vaginal candidosis are described. The epithelial surface is covered with adherent masses composed of desquamated and destroyed epithelial cells and leucocytes impregnated with proteinaceous fluid and penetrated by pseudomycelium. The outer epithelial layers are characterized by dystrophic and necrobiotic changes, desquamation, formation of fissures and small cavities.

Terminal intramuscular motor innervation and motor end-plates in thyrotoxic myopathy.

Thyrotoxic myopathy was induced in 64 mice. Examination of their muscles revealed excessive axonal branching and degenerative changes of preterminal axons. Moreover, the mean diameter of their end-plates decreased and the levels of end-plate cholinesterase appeared to be reduced.

The impact of butyric acid on the cardiovascular system.

The influence of sodium salt of butyric acid (C4H7NaO2) on the functional state of the cardiovascular system was studied on 12 guinea-pigs and 15 rabbits by the thermodilution method. The following parameters were determined: cardiac output (CO), arterial blood pressure (AP), total peripheral vascular resistance (TPVR), and in rabbits the heart rate (HR). It was found that butyric acid induces significant changes in TPVR, which correlate with changes in CO and AP.
