Idiopathic Developmental Dysplasia of Hip in a Female Child with a Rare Epidermal Syndrome- A Case Report.

Introduction: Developmental dysplasia of the hip (DDH) describes a spectrum of disorders affecting the neonatal hip. Trachyonychia or twenty nail dystrophy refers to thin, brittle nails with excessive longitudinal ridging affecting all twenty nails. Alopecia universalis congenita (ALUNC) is a rare anomaly affecting skin and appendages.

Heart rate recovery as a predictor of mortality with or without revascularization.

Increased heart rate during graded exercise is related to increased sympathetic activity and withdrawal of vagal tone. Return of heart rate towards baseline immediately after exercise is usually due to resurgence of vagal tone. As it is an established fact that cardiovascular morbidity and mortality in part has direct relation with parasympathetic dysfunction, it is natural that reduced heart rate recovery (HRR) after exercise, a parameter of parasympathetic dysfunction, could be a predictor of morbidity and mortality.

Study on the diagnostic accuracy of left atrial enlargement by resting electrocardiography and its echocardiographic correlation.

M-mode echocardiography has been accepted as gold standard for measuring left atrial (LA) size. Electrocardiography (ECG) offers a simple, non-invasive, cost-effective and reproducible method to assess LA size and it is mostly in agreement with echocardiography though discrepancies exist. ECGs and echocardiograms were obtained in 100 consecutive patients suspected of having left atrial enlargement due to different underlying heart diseases.
