[EX Q]: Abstract: The results of forty core-decompression procedures that were performed for ischemic necrosis of the femoral head in thirty-one patients over a four-year period were retrospectively reviewed to ascertain the effectiveness of the procedure. The data did not support the published rates of success of the procedure for Stage-1 and Stage-2 lesions. With a mean length of follow-up of eighteen months, 60 per cent of the hips that had a decompression prior to collapse of the femoral head demonstrated progression of the lesion and were judged to be a failure by clinical or radiographic criteria. Computerized tomographic scans and magnetic resonance imaging proved to be 100 per cent sensitive for diagnosis in preoperative testing; isotopic bone-scanning was less sensitive (80 per cent). Functional intraoperative testing by the method of Ficat did not provide added sensitivity or specificity to the results of the preoperative bone scan. A postoperative or intraoperative fracture occurred in four hips, for an incidence that exceeded any in previously published reports. We concluded that core decompression should be considered a relatively ineffective procedure with significant morbidity.

[EX Q]: Abstract: Several conditions that contribute to drowning and near drowning must be considered in the treatment of near-drowned victims. Regardless of the cause, mechanical ventilation should begin as soon as possible and closed-chest cardiac massage should be administered when there is any question about the adequacy of cardiac output. After aspiration of either fresh or seawater, a large intrapulmonary physiologic shunt can occur, which requires aggressive mechanical ventilatory support to ensure adequate oxygenation and to return pulmonary function to normal. Near drowning is a multisystem disease and, while abnormalities of the lung and brain have been emphasized, definitive therapy must be tailored to each patient and must address all of the patient's needs.

[EX Q]: Abstract: The IgG and IgM specific antibodies against a panel of 23 anaerobic gut bacteria were examined in Crohn's disease, ulcerative colitis, and healthy controls. Four of the organisms, Bifidobacterium bifidum, Coprococcus comes (ME46), Coprococcus comes (Sp4), and Eubacterium limosum gave abnormal antibody titres in Crohn's disease compared with those of controls. In Crohn's disease specific IgG antibodies to three of the organisms were low and the IgM antibodies were higher than those of controls. IgM antibodies were also raised in ulcerative colitis. Antigenic cross reactivity could be shown between some of these organisms. The possible clinical importance of these abnormal antibody responses to specific organisms is unexplained.
