In a 16-member black kindred with Fabry's disease, four hemizygous males had plasma alpha-galactosidase levels less than 6% and seven heterozygous females had plasma alpha-galactosidase levels between 10% and 50% of normal. A 16-year-old index male had hypertension with left ventricular hypertrophy, abnormal renal function, tortuous retinal veins, "myelin" inclusions in bone marrow macrophages, and intraepithelial inclusion bodies in the kidney. Scrotal angiectasia developed a year after diagnosis. The three other affected males had left ventricular hypertrophy and retinal vein tortuosity. Of the seven carrier females, five had frequent headaches, four had retinal vessel changes, three had proteinuria with normal renal function, and two had bundle-branch blocks on ECGs. There was no deuteranomalopia in this family, although the inheritance pattern of the Fabry gene is X-linked recessive.

Radiation injury to arteries can represent a significant complication of therapeutic irradiation, even when the dosage used has not been excessive as judged by approved protocols. Children in whom therapeutic abdominal irradiation has been used should be monitored indefinitely for the development of hypertension. The presence of hypertension in such children with normal blood urea nitrogen (BUN) and creatinine, and without proteinuria, should prompt investigation for a renovascular lesion. Standard bypass procedures are usually effective, although the long-term success may be compromised by continuing changes in affected vessels.

The purpose of the present paper was to study clinical, morphological and immunological aspects of late rejection of renal allotransplants. We have, therefore, analyzed the occurrence and nature of renal transplant disease and graft failure among 125 recipients surviving for 1 to more than 8 years after transplantation. In this population transplant disease as defined by the appearance of heavy proteinuria and/or steadily declining graft function occurred in 22 patients. At the closure date of the study on December 31, 1972 complete graft failure had occurred in 12 of these 22 patients and 4 of these have died. In addition two patients died in the presence of normal graft function, due to chronic hepatitis and metastatic cancer respectively. As based on clinical findings, pathophysiological features and renal lesions the patients with late transplant disease were classified into two groups and described accordingly. Group A, termed glomerular transplant disease, included a majority of 16 patients, constituting a rather homogenous idsease entity in relation to course of disease, clinical findings and renal lesions as studied by light-, immunofluorescence- and electron microscopy. All these patients presented with heavy proteinuria, which was non-selective in all but two, resulting eventually in complete loss of graft function in eight cases. All these patients developed hypoalbuminemia and hypercholesterolemia, and one half manifested a classical nephrotic syndrome. Arterial hypertension occurred in all patients except two. Glomerular structure as studied by light microscopy revealed a number of lesions of a rather polymorphous pattern in all patients in group A. Endomesangial proliferation, hyperplasia and segmental proliferation of epithelial cells and thickening of capillary walls were prominent features, although the degree of severity, extension and type of lesion occurred in such varying proportions that classification into any well characterized category of glomerulonephritis was not possible. All cases in group A revealed immune deposits, most frequently containing IgG, IgM, complement and fibrinogen. IgA, IgD and IgE were also demonstrated in a lesser proportion of cases in this group. The immunofluorescent pattern was a mixed granular and linear, and in no case strictly linear or granular alone. The ultrastructural investigation contains a detailed analysis of the

The mean basal specific activity (S.A.) of the glutamic oxaloacetic transaminase of erythrocytes (EGOT) for a group of 64 pregnant women was lower (p less than 0.001) than the value for the cord bloods of newborn infants, and lower (p less than 0.001) than the value for adults who had a top limit of S.A. of EGOT. In establishing the top limit of the S.A., it is important that the mean basal S.A. of the cord bloods from 49 newborn infants was identical to the mean basal S.A. of adults who had an adequate supplement of pyridoxine. There were no differences in the mean basal S.A.'s of the cord bloods between asymptomatic mothers and mothers who had anemia, edema, hypertension, proteinuria and glucosuria. An infant may be born with a top limit of S.A. which is non-deficient in pyridoxal 5'-phosphate, but a mother can have a low level of the transaminase, and which is deficient in the coenzyme.

The typical patient with diabetes mellitus seen at major hospitals in Papua New Guinea between 1974 and 1977 had florid symptoms, a very high blood glucose, was non-obese and non-ketotic and, frequently had neuropathy and proteinuria. In 25% hypertension was present which was significantly more common in the presence of proteinuria. Diagnosis was often delayed by failure to test urine for glucose and treatment was usually ineffective so that coma, usually non-ketotic, severe infections and gangrene occurred frequently. Although not as common as in other South Pacific countries, diabetes is increasing in Papua New Guinea. The provision of simple adequate facilities to test urine for glucose in all hospitals and the establishment of diabetic out-patient clinics in major centres to instruct both patients and other health workers are essential to improve treatment and reduce mortality and morbidity.

In a series of 26,209 patiens, the incidence of pre-eclampsia was 9.3%, being significantly higher in primiparae (14.1%) than multiparae (5.7%) (P less than 0.001). In patients with early-onset pre-eclampsia there were highly significant (P less than 0.001) increases in the incidences of proteinuria, severe hypertension, placental abruption, fetal growth retardation, neonatal asphyxia and perinatal mortality. There were no significant differences between the incidences of these complications in primiparae and multiparae. The incidence of subnormal oestriol excretion was increased before the emergence of early-onset pre-eclampsia with equal to significance (P less than 0.001) in primiparae and multiparae. Eclampsia was more common in patients with late-onset pre-eclampsia, but not significantly so.

Disorders associated with hypertension during pregnancy, which are often linked with oedema and/or proteinuria and are variously termed toxaemia of pregnancy, EPH gestosis, pre-eclampsia, and eclampsia, are of unknown etiology, although they have been known for a long time and many attempts have been made to classify and explain them. In this paper, the author draws attention to the problems of standardizing values for blood pressure, proteinuria, and oedema and of determining their value in the diagnosis of the disorder. Different classification schemes are described and the problems of comparison between them are stressed. The frequency of the hypertensive disorders of pregnancy in different countries and groups at special risk are discussed. Finally, recommendations are made on the types of research and health care needed to combat the problem.

Two major categories of membranoproliferative glomerulonephritis (MPGN) designated type 1 and 2 MPGN are currently recognized, largely on the basis of characteristic morphologic and immunofluorescence features. In contrast to experience reported from outside the United States, type 2 MPGN has been observed rather infrequently in this country. In a retrospective clinicopathologic study, 24 kidney specimens obtained from 10 children and young adults including seven females and three males (mean age: 13 years) with type 2 MPGN were identified using light, immunofluorescence, and electron microscopy. The histopathologic findings were related to the clinical course of each patient. When initially seen all patients had hematuria and proteinuria, three were nephrotic, and five were mildly hypertensive. A single patient was mildly azotemic. Eight patients had experienced an upper respiratory ifnection preceding their illness, although only one patient had evidence of a streptococcal pharyngitis. During a period of follow-up averaging 10 years, eight patients were nephrotic at some time during their illness and seven were persistently so. Hypertension was a major problem in eight patients and renal function declined markedly within a year of its onset in five. Persistence of the nephrotic syndrome from early onset of the disease, especially when associated with hypertension, was an additional sign of poor prognosis. Four patients developed chronic renal failure and three received one or more renal allografts. Histologic evidence of recurrent disease was found in allografts from the three patients as early as 7 months after transplantation in the absence of clinical features indicative of recurrent glomerulonephritis. It is concluded that type 2 MPGN is a chronic progressive renal disease of unknown etiology and pathogenesis which chiefly afflicts children and young adults. Hypertension and the early and persistent presence of the nephrotic syndrome suggest a poor prognosis. The disease appears to be largely unresponsive to conventional forms of therapy. The disease recurs with great frequency in allografts, often in the absence of clinical evidence of recurrent glomerulonephritis.

92 cases of extramembranous glomerulitis (EMG) documented by histology and immunofluorescence have been studied. At the time of renal biopsy the clinical and biologic picture was as follows: no proteinuria in 2%, isolated proteinuria in 18%, nephrotic syndrome without hypertension or azotemia in 41%, and hypertension and/or azotemia associated with proteinuria or nephrotic syndrome in 39%. A possible cause of the EMG was found in 27 cases: it was drug-induced or toxic in 10 instances, paraneoplastic in 7, lupus in 5 and parasitic (loasis) in 5.65 cases are regarded as idiopathic. The evolution is known in 66 cases and varies with the etiology: it is usually benign in secondary forms except the paraneoplastic cases. In the idiopathic forms it results in hypertension or more or less severe chronic renal failure in 62% of cases. The prognosis cannot be established on the basis of the initial histology. No treatment has proved effective.

The risk to the transplanted kidney of vesicoureteric reflux was evaluated in 150 consecutive first cadaveric renal allografts surviving for over three months. Of the 119 (79 per cent) allografts studied by micturating cystography 29 (24 per cent) were shown to reflux. The presence of reflux was associated with urine leakage and reoperation, and with ureteric insertion involving a short intramural tunnel. Graft failure (graft nephrectomy or death from renal failure) occurred in 14 of 29 refluxing grafts as compared to 14 failures in 90 nonrefluxing grafts (P less than 0.01). Graft failure in the refluxing group was typically slow, and commonly associated with proteinuria, microscopic hematuria, hypertension and a biopsy appearance of mesangiocapillary glomerular change. Urinary infection, though frequent (69 per cent), was not more common in the group with than in that without reflux. Vesicoureteric reflux is an important cause of late renal-graft failure.
