RATIONALE Although cognitive deficits are well documented in patients with sleep apnea, the impact on memory remains unclear. OBJECTIVES To test the hypotheses that (1) patients with obstructive sleep apnea have memory impairment and (2) memory impairment is commensurate with disease severity. METHODS Patients with obstructive sleep apnea and healthy(More)
when a reading was taken because a sterile operating field impaired access to the patients. The radial pulse always disappeared before the femoral pulse, which always disappeared before the carotid pulse. The data were split into four subgroups: radial, femoral, and carotid pulses present (group 1), femoral and carotid pulses only (group 2), carotid pulse(More)
Two studies were performed to investigate the differences in pressure stability performance of the continuous positive airway pressure (CPAP) machines used by our patients. The variations of mask pressures during each respiratory cycle were measured during overnight studies of two groups of patients with obstructive sleep apnoea, who were using either a(More)
OBJECTIVES To assess whether ultrasonography alone is adequate for routine screening of childhood urinary infection, whether clinical features determine the need for further investigations, and which investigations are most appropriate. DESIGN Prospective survey of children with proved urinary infection and a preinvestigation record of clinical features.(More)
BACKGROUND Severe chest pain is common in mesothelioma. Percutaneous cervical cordotomy, which interrupts the spinothalamic tract at the C1/C2 level causing contralateral loss of pain sensation, is particularly appropriate in mesothelioma as the tumour is unilateral and systemic analgesia may be ineffective and is limited by harmful side effects. METHOD A(More)
We investigated the long-term effectiveness of cuirass-assisted ventilation, and examined whether mortality and morbidity could have been predicted at the time of admittance. Twenty five patients were commenced on nocturnal cuirass-assisted ventilation between 1983 and 1985, 10 with scoliosis or kyphosis, 8 with a thoracoplasty and 7 with neuromuscular(More)
Two patients with Gaucher's disease during pregnancy are reported. In one there were severe puerperal hemorrhagic complications attributable to thrombocytopenia secondary to infiltration of the reticuloendothelial system by Gaucher cells. The conclusion as reported in previous literature, which is reviewed, regarding the absence of hemorrhagic complications(More)
OBJECTIVE To test the hypothesis that testicular maldescent is rarely congenital in the absence of a complete hernial sac. PATIENTS AND METHODS The study comprised 110 boys undergoing orchidopexy. Operative findings (complete hernial sac versus no hernial sac) were compared with recorded testicular descent at birth. RESULTS Among 70 testes recorded as(More)
BACKGROUND The treatment of symptomatic pulmonary aspergillomas can be difficult. One approach has been to deliver antifungal drugs directly into the lung cavity. The use of this method of treatment is described in which an indwelling percutaneous catheter is used which avoids repeated needlings of the cavity and may allow extended treatment on a(More)
