Abstract: A retrospective review of the cases of 180 patients who had 198 acute open fractures of the tibial shaft and were admitted to a multiple-trauma referral center over a three-year period revealed an incidence of accompanying compartment syndrome of 9.1 per cent (eighteen fractures in sixteen patients). Each of the eighteen compartment syndromes was documented by measurements of intracompartmental pressure that were obtained by the saline-injection technique, and all were treated by four-compartment fasciotomy. The incidence of compartment syndrome was found to be directly proportional to the degree of injury to soft tissue and bone; this complication occurred most often in association with a comminuted, grade-III open injury to a pedestrian. The physician must maintain a high index of suspicion to detect a compartment syndrome in the patient who has multiple trauma, as its clinical signs and symptoms may be masked by a closed injury of the head or the need for ventilatory support or prolonged anesthesia for other surgical procedures.
Which is the apt title for the abstract? option1: Compartment syndrome in open tibial fractures. option2: Postchemotherapy esophagitis: the endoscopic diagnosis and its impact on survival.
answer:
Compartment syndrome in open tibial fractures.

question:
Abstract: Five patients with Kaposi's sarcoma seen and treated at the Louisiana State University Medical Center in Shreveport from 1970 to 1984 are presented. A complete response was observed in two patients who received extended-field irradiation. Results obtained with external beam radiotherapy for this disease from other reported patients series are summarized.
Which is the apt title for the abstract? option1: Kaposi's sarcoma: report of five cases treated with radiotherapy. option2: Remodeling of the temporomandibular joint disk and posterior attachment in disk displacement specimens in relation to glycosaminoglycan content.
answer:
Kaposi's sarcoma: report of five cases treated with radiotherapy.

question:
Abstract: The combined effects on performance of two anxiolytics with different mechanisms of action were evaluated double-blind and crossover in 12 healthy students. Objective (tracking, divided attention, Maddox wing, etc.) and subjective (visual analogue scales and questionnaires) tests were done before and twice after single oral doses. Diazepam (0.15 and 0.30 mg/kg) impaired performance dose relatedly and rendered the subjects drowsy, calm, mentally slow, and clumsy. Buspirone (15 mg) proved inactive in objective tests but matched diazepam (0.30 mg/kg) subjectively. In combinations, buspirone added to the effects of diazepam in Maddox wing and letter cancellation but tended to counteract diazepam effects on divided attention and learning acquisition. Subjectively buspirone prolonged diazepam-induced sedation. Increased calmness caused by diazepam was not affected by concomitant buspirone. It is suggested that combining small doses of buspirone to diazepam does not cause any additional decrement in psychomotor performance. Possible advantages of the diazepam-buspirone combination in therapeutic use are discussed.
Which is the apt title for the abstract? option1: Combined effects of buspirone and diazepam on objective and subjective tests of performance in healthy volunteers. option2: Pica in pregnancy [letter]
answer:
Combined effects of buspirone and diazepam on objective and subjective tests of performance in healthy volunteers.
