Two patients who developed biochemical and histological evidence of hepatitis while taking the anti-anginal drug perhexiline maleate are described. The pathological changes were those of mild to moderate fatty change together with a hepatitis which resembled alcoholic hepatitis, including in one patient the presence of material which by light microscopy was… (More)
The change of the staple diet of Black South Africans from sorghum to maize (corn) is the cause of the epidemic of squamous carcinoma of the oesophagus. For many years sorghum was the staple diet of Black South Africans. From approximately the early part of the twentieth century, maize gradually replaced sorghum. Squamous carcinoma of the oesophagus was… (More)
A patient is presented with primary choriocarcinoma of the fallopian tube arising from a tubal pregnancy. Treatment consisted of an initial operation including adnexectomy and resection of bilateral ovarian thecalutein cysts, followed by chemotherapy. The patient delivered a healthy infant 2 years later, and is alive and well 5 years after the event.
The first case to appear in the world literature is described of an embryonal rhabdomyosarcoma in a child arising from the region of the ampulla of Vater and projecting into the lumen of the duodenum.
Autopsy material was examined from cases diagnosed as malignant nephrosclerosis in the years 1956-1961, a period when adequate antihypertensive therapy had not yet become available, a second group of malignant nephrosclerosis from the years 1970-1980, an era during which effective antihypertensive therapy was available, and a third group of essential benign… (More)
Oesophageal specimens derived from 70 patients with established invasive squamous cell carcinoma of the oesophagus were histologically reviewed with special reference to the morphological manifestations of human papillomavirus (HPV) infection. Epithelial changes fulfilling the criteria for HPV infection were noted in 23 cases (33%). The presence of HPV… (More)
The nucleotide sequence of the mRNA that codes for Fab fragments from two chimpanzee monoclonal antibodies has been determined. Both antibodies have high affinity and good specificity for digoxin. Four domains from the two antibodies have been sequenced: the constant domains of the kappa and lambda light chains, the variable domain of the lambda light… (More)
Human monoclonal antibodies, owing to their decreased immunogenicity, are expected to be an improvement over mouse monoclonal antibodies for in vivo therapy. Human and primate monoclonal antibodies are best produced with a human x mouse heteromyeloma. Several human chromosomes are stable in the human x (human x mouse) hybrids. Chimpanzee anti-digoxin… (More)
Over the last 17 years there has been a significant reduction in the prevalence and severity of dietary iron overload in urban blacks of Johannesburg. This is attributed to a decrease in the consumption of traditionally brewed beer of high iron content over this period. A 40% reduction was found in hepatic iron concentrations measured in necropsy specimens… (More)
