BACKGROUND The natural course of adult hepatitis B virus (HBV)-related membranous nephropathy in areas where HBV infection is endemic (characterized by vertical and horizontal transmission of HBV in early childhood) has not been fully defined. METHODS We evaluated the clinical features, pathological findings, serologic profiles, therapeutic responses, and(More)
OBJECTIVES To evaluate the effectiveness of sodium ramping (profiling) in reducing hypotensive episodes and symptoms during haemodialysis. DESIGN Prospective study. SETTING Regional hospital, Hong Kong. PATIENTS Thirteen patients who experienced frequent episodes of hypotension and/or symptoms such as cramps, dizziness, chest pain, nausea, vomiting,(More)
The frequency of hepatitis B surface antigen (HBsAg) was studied in the sera of 311 patients with various forms of primary glomerulonephritis and 43 patients with lupus nephritis. HBs antigenaemia was detected in 69 of the 311 patients (22 per cent) with primary glomerulonephritis and this prevalence of HBsAg carrier was significantly higher than that in(More)
BACKGROUND We hypothesized that autoregulatory changes in arteriolar blood volume (aBV) that develop distal to a stenosis can be measured with myocardial contrast echocardiography, allowing coronary stenosis detection at rest without recourse to stress. METHODS AND RESULTS Patients with varying degrees of coronary artery stenosis on quantitative(More)
INTRODUCTION Torsade de Pointes (Tdp) is a form of polymorphic ventricular tachycardia in the setting of prolonged QT interval. Any drug that prolongs repolarisation, and hence QT interval, may cause Tdp. Predisposing factors of drug-induced Tdp include female sex, bradyarrhythmia and hypokalaemia. METHODS We retrospectively analysed the case notes of 13(More)
A 21-year-old woman developed severe muscle paralysis after sniffing toluene-containing thinner solution for 2 weeks. Her serum chemistries revealed severe hypokalaemia and a normal anion gap hyperchloraemic metabolic acidosis secondary to renal tubular acidosis. Her initial presentation mimicked hypokalaemic periodic paralysis, but toxicology screening of(More)
INTRODUCTION Isolated non-compaction of ventricular myocardium (INVM) is a rare disorder of myocardial morphogenesis in the absence of other cardiac anomalies. Both sporadic and sex-linked recessive forms have been described. It can be identified with two-dimensional echocardiography. CLINICAL PICTURE We report a series of 3 cases of adult males with INVM(More)
We identified a patient with primary hyperoxaluria type 2 (PH2) showing recurrent stone formation, nephrocalcinosis, end-stage renal failure, and rapid oxalate deposition after renal transplantation from a living related donor. Urinary organic acid analysis performed after renal transplantation confirmed the diagnosis of PH2. We analyzed the glyoxylate(More)
