[EX Q]: Abstract: We correlated the level of vitiligo antibodies to the extent of depigmentation in thirty-two patients with vitiligo. Vitiligo antibodies were assayed by protein A-sepharose immunoprecipitation method. Antibodies were present in four of eight (50%) patients with minimal vitiligo (less than 2% body surface involved), in nine of ten (90%) patients with moderate vitiligo (2 to 5% surface involved), and in thirteen of fourteen (93%) patients with more extensive disease (greater than 5% surface involved). The level of vitiligo antibodies in the three groups expressed as a binding index was 2.9% +/- 2.03, 5.6% +/- 2.92, and 8.0% +/- 3.03 SD, respectively. These results suggest that there is a relation between the incidence and level of vitiligo antibodies and the extent of depigmentation in vitiligo.
Which is the apt title for the abstract? option1: Correlation between vitiligo antibodies and extent of depigmentation in vitiligo. option2: Fatal acute aortic regurgitation in a person performing the Heimlich maneuver [letter]

[EX Q]: Abstract: Information on ethyl alcohol intoxication in children is scarce. A retrospective study was conducted by chart reviews of 27 patients with documented ethanol ingestion admitted to the Alberta Children's Hospital, Foothills Provincial Hospital, Calgary General Hospital or Holy Cross Hospital from 1969 to 1984. Six patients had hypoglycemia and one experienced a convulsion. The rate of alcohol elimination was found to be greater than 6.2 mM/L/hr (28.4 mg/dl/hr), approximately twice the rate seen in adults. Six patients had hypokalemia, and two had severe metabolic acidosis.

[EX Q]: Abstract: From 1966 to 1983, skeletal suspension was used at the Shriners Burns Institute, Galveston, Texas, for the treatment of 626 burned pediatric patients who had 1128 affected extremities. Skeletal suspension was used for 863 acutely burned extremities (76.5 per cent) to facilitate skin-grafting and in 265 extremities (23.5 per cent) for functional positioning in the surgical correction of burn-acquired deformities. In a retrospective examination of these patients, there were fifty complications (4.4 per cent) related to the skeletal suspension, of which forty-five (4.0 per cent) were infections. All infections resolved with removal of the pins or the administration of antibiotics, or both. With this established low rate of complications, skeletal suspension continues to be a useful adjunct in the care of the severely burned pediatric patient.
