BACKGROUND The development of portable liquid oxygen systems, capable of delivering high flow rate oxygen for long periods, justifies reassessment of the value of supplemental oxygen to aid exercise tolerance in patients with chronic respiratory insufficiency. The type of exercise test and the low oxygen flow rates previously used may account for the(More)
OBJECTIVE To investigate the time course of an epidemic of asthma after a thunderstorm, characteristics of patients affected, and the demand on emergency medical resources. DESIGN Study of registers and records in accident and emergency departments and questionnaire to staff. SETTING London area. SUBJECTS All patients presenting at 12 accident and(More)
Cough flows and pressures were measured during cough augmentation in healthy subjects and patients with bulbar and nonbulbar amyotrophic lateral sclerosis. Manual assistance increased flow 11% in bulbar (p < 0.01) and 13% in nonbulbar (p < 0.001) patients. Mechanical insufflation-exsufflation increased flow 17% in healthy subjects (p < 0.05), 26% (p <(More)
BACKGROUND Regional weaning centres provide cost effective care for patients who have undergone prolonged mechanical ventilation. There are few published European data on outcomes in these patients. METHODS Patients admitted for weaning to the Lane Fox Respiratory Unit (LFU) between January 1997 and December 2000 were identified. The proportion weaned(More)
UNLABELLED The objective of our study was to see if incisional and intraperitoneal bupivacaine with epinephrine produces analgesia after total abdominal hysterectomy. Forty-six ASA physical status I and II patients received a standardized anesthetic, patient-controlled analgesia (PCA) morphine, and rectal paracetamol 1 g every 6 h. Patients were randomized(More)
The influence of supplemental oxygen on exercise performance was assessed in 17 patients with severe airflow obstruction. Exercise capacity was measured by the six minute walking distance, by an endurance walking test, and by an endurance cycling test and comparison was made with performance when the patient was breathing air. In addition, the relation(More)
BACKGROUND Advances in management have led to increasing numbers of patients with Duchenne muscular dystrophy (DMD) reaching adulthood. Older patients with DMD are necessarily severely disabled, and their management presents particular practical issues. AIM To review the management of a late adolescent and adult DMD population, and to identify areas in(More)
A 61-yr-old male presented with apparent idiopathic central sleep apnoea but after 4 yrs developed features of autonomic, cerebellar and extrapyramidal dysfunction consistent with a diagnosis of multiple system atrophy (MSA). Though central sleep apnoea can occur in multiple sleep apnoea, it is less frequent than obstructive sleep apnoea and occurs in the(More)
Radionuclide transit (RT) is a noninvasive test of esophageal function with a sensitivity equivalent to manometry. Using RT, 34 patients with progressive systemic sclerosis (PSS), 15 with diffuse scleroderma and 18 with the CRST variant, were studied and compared to 22 patients with other connective tissue diseases and 20 normal volunteers. Abnormalities(More)
