Effect of yogic exercises on physical and mental health of young fellowship course trainees.

A study was undertaken to observe any beneficial effect of yogic practices during training period on the young trainees. 54 trainees of 20-25 years age group were divided randomly in two groups i.e. yoga and control group. Yoga group (23 males and 5 females) was administered yogic practices for the first five months of the course while control group (21 males and 5 females) did not perform yogic exercises during this period. From the 6th to 10th month of training both the groups performed the yogic practices. Physiological parameters like heart rate, blood pressure, oral temperature, skin temperature in resting condition, responses to maximal and submaximal exercise, body flexibility were recorded. Psychological parameters like personality, learning, arithmetic and psychomotor ability, mental well being were also recorded. Various parameters were taken before and during the 5th and 10th month of training period. Initially there was relatively higher sympathetic activity in both the groups due to the new work/training environment but gradually it subsided. Later on at the 5th and 10th month, yoga group had relatively lower sympathetic activity than the control group. There was improvement in performance at submaximal level of exercise and in anaerobic threshold in the yoga group. Shoulder, hip, trunk and neck flexibility improved in the yoga group. There was improvement in various psychological parameters like reduction in anxiety and depression and a better mental function after yogic practices.

Video-assisted thoracoscopic surgery for closure of patent ductus arteriosus in children.

Video-assisted thoracoscopic surgery (VATS) was recently described as an approach to clip the patent ductus arteriosus (PDA). Between May 1994 and May 1996, we performed this procedure on 34 children below 12 years of age (mean 7 years). Thirty-two had an isolated PDA and two had associated small perimembranous ventricular septal defect (VSD), diagnosed on echocardiography and colour flow mapping. None had pulmonary arterial hypertension. The procedure was successful in 33 (97%) children confirmed by absence of residual shunt on serial echocardiography. Complications in the form of pneumothorax (1) and vocal card paralysis (2) were encountered in three children. The overall hospital stay was reduced to five days. In conclusion, the technique of PDA clipping using VATS is easy to learn and highly successful with acceptable risk of complications.

Tubercular lymphadenitis: clinical manifestations.

One hundred and thirteen children suffering from tubercular lymphadenitis proven histopathologically, were studied for clinical and laboratory features. Age distribution was equal in all age groups except during infancy when it was rare. Sex ratio indicates a male preponderance with male to female in the ratio of 1.5:1 (67:46). Family history of contact with known tuberculous patient was positive in 19 (17%) children, 44 (40%) had received BCG, and 98 (88%) were either normal nourished or had mild malnutrition. Cervical, axillary and inguinal nodes were found in 90 (80%), 14 (12%), and 8 (7%) children respectively. Epitrochlear node was found in only 1 child. 11 (10%) children had discharging sinus, all being in cervical group. The consistency of nodes was firm in 98 (87%), fluctuation was present in 15 (13%). In 87 (77%) lymph nodes were matted. Hepatomegaly of more than 2 cm was present in 13 (11%) and spleen was enlarged (> 2 cm) in 4 (4%) only: Mantoux test was positive in 96 (85%) children and chest X-ray was abnormal in 25 (22%) cases. Findings suggest that tubercular adenitis occurs in all age groups with equal frequency. It can occur in vaccinated children also. It may be a sole manifestation of tubercular infection. The cervical nodes are predominantly involved. There is no typical location of nodes in individual groups but multiplicity and matting of nodes are characteristic features of tubercular adenitis in children.

Pulmonary alveolar microlithiasis--report of three cases with pulmonary function and exercise studies.

Pulmonary alveolar microlithiasis is a rare disease involving accumulation of calcific concretions in the alveoli of the lungs. Three cases of this disease are reported with their varying and unusual clinical features. Radiologic studies demonstrated presence of diffuse calcific densities in the lungs with varying degrees of emphysematous changes. Bone scans showed diffuse uptake of the tracer in the lungs. Pulmonary functions showed hyperinflation and small airways dysfunction in one case besides the presence of restrictive ventilatory defect. Exercise studies demonstrated arterial oxygen desaturation on exercise.
