Oral fluid testing is an effective alternative to serum antibody testing for surveillance of human immunodeficiency virus (HIV) and hepatitis B infections, and is being extended to hepatitis C infections. The objective of this study was to determine and compare the sensitivity and specificity of a modified commercial assay for the detection of antibody to(More)
Amino acid concentrations were determined in plasma, whole blood, cerebrospinal fluid and brain tissue of 45 patients with grade 3 or 4 coma due to fulminant hepatic failure. The concentration of 15 of the 19 amino acids determined were significantly increased in blood and the increases were greatest for the amino acids concerned with neurotransmitter(More)
Doxorubicin (60 mg/m2 at 3-weekly intervals to a maximum total of 550 mg/m2) induced clinical remission in 14 (32%) of 44 patients with hepatocellular carcinoma. In 3 of those who responded, hepatic arteriography showed clearing of the previously extensive tumour circulation, and in a 4th there was disappearance of the tumour on serial ultrasound(More)
BACKGROUND Chewing the leaves of the Qat plant (Catha edulis) for their pleasurable central stimulant effect is a habit that is widespread in Yemen and certain areas of East Africa. The use of the Qat leaves is believed to cause a variety of gastrointestinal and genito-urinary symptoms as well as sleep disturbance. We studied the subjective effects of(More)
The prevalence of hepatitis C infection and possible predisposing factors was assessed in a renal unit. Of 343 patients at our renal dialysis centre, 37 (10.8%) were anti-HCV positive by a 1st-generation assay (ELISA, Ortho/Chiron) and confirmed positive in 35 (10.2%) with a 2nd-generation test (UBI, New York). Anti-HCV positivity was significantly(More)
BACKGROUND Liver involvement in sarcoidosis is variable and can occur in the absence of pulmonary disease. Data on the natural history of hepatic sarcoid and response to therapy are lacking. This study investigates hepatic dysfunction complicating lung disease and significant liver involvement presenting independent of pulmonary sarcoid. PATIENTS AND(More)
Two cases of scleroderma and primary biliary cirrhosis are described. One had systemic sclerosis with primary biliary cirrhosis of six years' duration at the stage of ductular proliferation. The other had the C.R.S.T. syndrome (calcinosis, Raynaud's phenomenon, sclerodactyly, and telangiectases) with primary biliary cirrhosis at the florid stage. Several(More)
BACKGROUND The leaves of Khat are chewed for their central stimulant effect, but their use may cause anorexia and constipation. METHODS Gastric emptying of a radio-labelled semi-solid meal was measured in 12 healthy volunteers on two occasions a week apart. Subjects chewed either Khat leaves (Catha edulis) or lettuce for 2 h before the study. RESULTS(More)
