Study of fingerprint classification and their gender distribution among South Indian population

Identification of an individual plays a vital part of any medicolegal investigation. Fingerprint is considered to be the most accurate and reliable indicator in identification.The present study was conducted on 500 South Indian subjects to determine the individuality and the predominant fingerprint pattern among South Indian population. Two-hundred and fifty males and 250 females of South Indian origin were included for this study and rolled prints were taken from all the 10 digits and the same were stored on a proforma.The most frequent fingerprint pattern was ulnar loop in the total population, as well as in the sex wise distribution.     

Systemic necrotizing vasculitis associated with childhood sarcoidosis

Childhood sarcoidosis is a rare disorder with protean manifestations. The case of a child with prolonged fever, hepatosplenomegaly, pancytopenia, and systemic necrotizing vasculitis manifesting as fever, rash and skin infarctions, digital pregangrene, and foot drop is reported. This is the first case of systemic necrotizing vasculitis reported in sarcoidosis. The fulminant course of the disease required treatment with intravenous pulsed cyclophosphamide and high doses of corticosteroids. The spectrum of vasculitis in childhood and adult sarcoidosis is reviewed.     

Upper Airway Obstruction With Hypoxaemia And Sleep Disruption In Down Syndrome

Six of 12 children with Down syndrome (DS) tested by means of long-term tape-recordings of oxygen saturation, breathing movements and expired CO2 were found to have previously undetected and severe upper airway obstruction during sleep. In five cases the obstruction occurred in the pharynx and in the sixth it was due to bilateral choanal stenosis. When compared with age-matched controls, overnight tape-recordings showed episodes of abnormal arterial hypoxaemia and an abnormally elevated end-tidal CO2. Episodes of obstruction were most marked during sleep associated with a non-regular breathing pattern. Abnormal episodes of hypoxaemia were associated with continued breathing movements. Sometimes there was no airflow (complete obstruction); at other times airflow continued normally or was reduced in amplitude (partial obstruction). During episodes of partial or complete airway obstruction the inspiratory waveform showed a characteristic shape. These results show sleep-related upper airway obstruction to be an often undetected complication of DS and all necessary measures should be taken to overcome the obstruction when it reaches the stage of producing abnormal hypoxaemia. Choanal dilatation and tracheostomy were successful in treating two of the children. Tonsillectomy and adenoidectomy were successful for one child, but only of marginal benefit for two others.
