Pre-Asiad '82 injuries in elite Indian athletes.

Elite Indian athletes who were undergoing training at the NIS, Patiala for the preparation of IX Asian Games held in Delhi in 1982, suffered 317 injuries during the 14 months of training. Of the injuries 64 per cent were observed in males, while 36 per cent were observed in females. Most of the injuries seen were in the lower limbs (59.2 per cent) and when classified according to the tissues involved, most of the trauma was seen in ligaments (38 per cent). Female sprinters and male throwers contributed most injuries. On average, each athlete sustained three injuries during the total training period by which 50 days of training was lost in nursing various kinds of injuries. Preventive measures of lower limb injuries, vigorous treatment for athletes preparing for a competition and maintenance of cardiorespiratory fitness during treatment is an important task of sports physicians and coaches.

Pulmonary capacities of different groups of sportsmen in India.

Pulmonary functional capacities, vital capacity (VC) maximum voluntary ventilation (MVV), forced expiratory volume in 1 second and FEV 1.0 (per cent VC) of 168 sportsmen belonging to different sports activities and of 10 sedentary individuals have been studied. It was observed that all these pulmonary functional capacities of different groups of sportsmen were higher than those of the sedentary group. The mean VC of the basketball, boxing, cricket, football, hockey and the table tennis groups, the mean MVV of all the groups except the athletic, badminton and football groups, and the mean FEV 1.0 of football, hockey, swimming and volleyball groups were significantly higher than those of the sedentary group. The mean values of all the three pulmonary functional capacities of only the hockey group were found to be significantly higher than those of the sedentary individuals. The available reported pulmonary capacity values, except FEV 1.0 of a few groups of sportsmen studied abroad, were higher than those of their counterparts studied here. These might be due to the ethnic variation as well as the variation in age, body size and level of physical fitness which influence the different pulmonary capacities.

Clinical significance of the comet-tail artifact in thyroid ultrasound.

The comet-tail artifact is commonly encountered in a variety of clinical conditions; however, its presence and significance in a thyroid nodule has not been documented before. We document its presence in 100 patients who underwent ultrasound examinations of the neck and thyroid. None of the thyroid nodules showed any evidence of malignancy on repeated fine-needle aspiration cytology (FNAC). In 85% of patients with the artifact, abundant colloid was seen on FNAC, suggesting that the artifact may be related to the presence of colloid. Four different patterns of distribution of the artifact within the nodule were noted and these helped to determine the size of the needle to be used for a successful aspiration.

Is routine computed tomographic (CT) scanning necessary in suspected basal skull fractures?

The aim of this prospective observational study was to assess the yield of routine fine-cut computed tomographic (CT) scans in patients with suspected basal skull injuries. Over an 8 month period in 1994, 500 consecutive head-injured patients were examined for clinical signs of basal skull fracture and underwent fine-cut (5 mm) CT scans through the skull base in addition to standard (10 mm) cuts through the vault. Clinical signs were present in 144 patients (144/500, 28.8 per cent) of which 75 (75/144, 52 per cent) had corresponding CT evidence of fracture. A further 22 patients (22/500, 4.4 per cent) had no clinical signs but fractures were seen on CT. The presence of cranial nerve injury, cerebrospinal fluid leak, epistaxis, periorbital bruising, and two or more signs, were more likely to be associated with positive CT scans (P < 0.001, chi 2 tests). The incidence of associated mass lesions was 50.5 per cent, of which 55.1 per cent required craniotomy. This was significantly higher than in patients without evidence of skull base fracture (16.6 per cent) (P < 0.001, chi 2 27.165). Six patients, two of whom had meningitis, required surgical repair of the dural defects seen on CT. The diagnostic yield of routine fine-cut CT scans in this sub-type of head injury is 52 per cent, and is of value in detecting associated mass lesions or significant dural defects which may require surgical intervention.

Cutaneous leishmaniasis in domestic dogs.

Cutaneous leishmaniasis was clinically diagnosed by non-healing skin lesions present on dorsal surface of nose (Snout) and outer surface of ear and by making impression smear from lesions. One per cent Berberine sulphate inoculated intralesionally on four occasions at weekly interval was found to be highly effective against cutaneous leishmaniasis in domestic dogs.

Canine model of terminal arterial aneurysm.

A canine model of terminal aneurysms using a venous pouch surgical technique is described. This model mimics the anatomy and hemodynamics of some types of carotid and basilar tip aneurysms. This technique produces aneurysms 15 x 21 mm in size. The aneurysms have been used to investigate the hemodynamics and treatment of terminal aneurysms.

An endovascular retrieving device for use in small vessels.

A new retrieval device for use in small vessels was evaluated in a canine model. Retrieval was attempted on 25 coils, three silicone balloons, and five catheter and guide wire fragments placed in the renal, pulmonary, hepatic, brachiocephalic, subclavian, carotid, and maxillary arteries. This was successful in 91% (30/33). The snare could also be selectively placed in the vertebral and proximal basilar arteries.
