The authors report the rare case of a dipygus monster. The infant had an omphalocele, a secondary pelvis with two limbs, an accessory pelvic kidney, and two bladders. At operation, the secondary pelvis and extremities were removed, and the omphalocele was repaired. The postoperative course was complicated by wound infection, urinary infections, proteinuria, cardiomegaly, and hypertension of renovascular origin. The infant died after right nephrectomy, 5 mo after the first operation.

The frequencies of retinopathy, proteinuria, hypertension, and electrocardiographic (ECG) abnormalities in 2025 diabetic subjects new to our clinic in Tokyo were analyzed in relation to status at initial visit with respect to age, estimated duration of diabetes, and fasting blood glucose. Frequency and severity of retinopathy increased markedly with duration of diabetes. A relationship was found between retinopathy at first visit and level of blood glucose at that time. Proteinuria also clearly increased with duration; its frequency was generally higher in older age groups. Frequency of hypertension increased with age up to 60 yr, but there was no association between prevalence of hypertension and duration of diabetes. ECG abnormalities also increased with age, although serious abnormalities were rare even in older subjects. Hypertension and ECG abnormalities were not more common in those with higher initial blood glucose values, and the frequencies of these aberrations did not increase with the duration of diabetes. ECG abnormalities were more common among hypertensives, especially in younger age groups. Despite the clear effect of degree and duration of hyperglycemia on microvascular complications, there was no evidence of a direct effect of hyperglycemia on macrovascular abnormalities in this study.

A series of 106 cases of polycystic kidneys in adults is presented. The main clinical, exploratory and therapeutic data are analyzed. The average age of the patients at the time of the first clinical manifestation was 35 years; average age at the time of diagnosis was 43 years. The most common forms of presentation included renal colics, blood hypertension, noncolic lumbar pain, macroscopic hematuria, and polydipsia-polyuria. The most frequent symptoms were: abdominal pain of any type (73 patients), polydipsia-polyuria (66 patients), blood hypertension (61 patients), macroscopic hematuria (47 cases), episodes of urinary infection (41 cases), and passing of calculi (22 cases). Seventy-eight subjects had arterial high blood pressure; it was easily controlled in all except 14 cases. Proteinuria was slight in all except two cases. Values for hematocrit and hemoglobin remained high in relation to the degree of renal insufficiency. The mean value of hematocrit in patients with creatinine clearance below 10 ml/min was 30 percent. Renal function decreased gradually, from normal to a clearance of less than 10 ml/min over a period of 12 years on the average. Diagnosis was based mainly on abdominal physical examination and intravenous urography; 89 patients had palpable abdominal masses. Urography revealed typical images of polycystic kidney in every case. The following associated conditions were also discovered: liver cysts (17 cases among 57 liver scanning; bilateral ovarian cysts in one case; Cacci-Ricci's disease in one case; and cerebral arterial aneurysms in another patient. Treatment was conservative with the aim to control arterial blood pressure and urinary infection. Twenty-nine patients required saline replacement; peritoneal dialysis was practiced in two cases and permanent hemodialysis was prescribed for 15 individuals.

A patient with a single functioning kidney presented with the nephrotic syndrome. On the basis of highly selective proteinuria, a diagnosis was made of lipoid nephrosis. Steroid therapy over a 2-year period did not control the disease. The patient eventually developed end-stage renal failure and malignant hypertension. Nephrectomy was performed to control the hypertension. Histological examination showed congenital dysplasia in one kidney and sclerosing glomerulonephritis, malignant nephrosclerosis, as well as dysplastic changes in the other.

It has long been known or suspected that phenytoin and probably phenobarbitone prescribed in pregnancy may lead to fetal malformations. The use of troxidone for epileptic women during pregnancy was reported in 1970 to lead to malformations. Over 50 instances of pregnancy in women taking troxidone have since been reported. In 8 of these the drug was used alone. 13 pregnancies resulted in abortion and 33 of the 40 survivors had a minor congenital anomaly, leading to death in 14. Complex congenital heart lesions with patent ductus, septal defects and aortic hypoplasia were apparent in half the survivors. Malformed or low-set ears were seen in nearly half the cases, palatal deformities were less common and evidence intrauterine growth retardation was frequently present. A 29-year-old mother taking troxidon and carbamazepine, and with a history of hypertension and proteinuria dating back to adolescence, delivered her first child prematurely. The child was small, showed deformed ears, displayed feeding problems and was found to be in cardiac failure with a systolic murmur and absent femoral pulses. Postnatal growth was retarded and after further cyanotic attacks a cardiac catheter study was performed. This showed a hypoplastic aortic arch with an anomolous origin of the left subclavian artery and patent ductus arteriosus, findings similar to those previously reported in neonates following maternal use of troxidone.

The clinical course of IgA Mesangial Deposits Glomerulonephritis (MDGN) has been investigated in 178 patients for 1 to 32 years (mean 6 years) from the onset of symptoms. Impairment of renal function occurred in 28 patients, 13 of whom required RDT or died in uraemia. Hypertension was observed in 67 patients. The actuarial survival rate at ten years was 91%. A significant correlation was observed between the occurrence of renal failure and the following features: absence of episodes of gross haematuria, early appearance of hypertension, marked proteinuria and sclerosing glomerular lesions. These data suggest that IgA MDGN has generally a very prolonged course, but in a few cases may evolve, sometimes early, to chronic renal failure.

In order to study the role of the renin-angiotensin system in patients with diabetic nephropathy, renin release and the juxtaglomerular apparatus were studied in 17 diabetic patients with proteinuria and in 23 without proteinuria; 8 normal subjects were used for conctrls. Despite hypertension and marked arteriosclerosis, plasma renin activity (supine posture) was normal; however, the renin response to salt restriction and upright posture was less in the diabetic patients with proteinuria than in the controls. Renal renin content, determined at autopsy, was also normal. Examination of the juxtaglomerular apparatus in the diabetic patients with proteinuria revealed hyalinization of the afferent and efferent arterioles in most of the glomeruli and various degrees of destruction of the juxtaglomerular cells. The findings suggest that renin production is not increased in diabetic patients with proteinuria plus marked vascular damage, and that the renin-angiotensin system in patients with diabetic nephropathy apparently does not play an important role in the exacerbation of hypertension or the degree of vascular damage.

Haematuria in children is either of glomerular or nonglomerular origin. In the latter case intravenous urography should always be performed. A renal biopsy is indicated if unexplained haematuria persists for at least one year or if an unfavorable prognosis is indicated by the appearance of hypertension, significant proteinuria or persistently low levels of serum complement (C3). The importance of screening the families of haematuric patients is emphasized. More than half of our cases with persistent or intermittent haematuria undergoing renal biopsy showed no or only minimal glomerular changes. In other children with a similar clinical picture more severe histological lesions were detected. In any case the kidney tissue obtained by biopsy should be examined by immunofluorescence and by electron microscopy. One of the most frequent causes for persistent or intermittent haematuria during childhood is Berger's disease (IgA/IgG nephropathy).

The clinical course of diabetic nephropathy was evaluated in 150 patients and the effect of hemodialysis in 68 of them. Proteinuria was the first sign of renal disease. Once renal dysfunction becomes evident, there is a rapid deterioration leading to dialysis within 3.0 +/- 0.2 years. Hypertension and circulatory congestion are common complications. The hypertension is probably volume dependent. Retinopathy was not invariably present at the onset of renal insufficiency but appeared with progression of renal failure. The course during hemodialysis was complicated by continued progression of diabetic vascular disease manifested by vascular access difficulties, worsening of retinopathy and blindness, and cardio- and cerebrovascular deaths. Mortality was higher than in nondiabetic dialysis patients.

Data from 38,636 pregnant women were studied to determine the best criteria for diagnosing pregnancy hypertension based on the constellation of clinical factors yielding poorest perinatal and long-term results to the offspring. It was found that the combination of maximum diastolic blood pressure and maximum proteinuria, as observed during the interval 28 weeks to term, provided the closest correlation with outcome. This information offered an objective means for establishing a classification of hypertension-hypotension in late pregnancy.
