Between 1975 and 1988 authors encountered 44 pregnancies in 26 women who had had chronic renal disease and unimpaired renal function before the conception. Complications during pregnancy and the outcome of pregnancy were studied. There were 5 spontaneous abortions between the 11th and 20th weeks of gestation, 1 therapeutic abortion, 3 still births at weeks 28, 32 and 33, 6 neonatal deaths at age of 26 to 35 weeks, 11 preterm newborns, 35 live births, 9 infants with intrauterine growth retardation including 4 preterm newborns and 1 fetal malformation and 2 cases with premature rupture of the fetal membranes. The pregnancies were complicated with anaemia in 23 cases, with urinary tract infection in 19, with hypertension in 16, with proteinuria in 12 and with edema in 11 cases. Increase in the serum creatinine value during pregnancy was found in 6 cases. These data indicate that the pregnancy in patients with chronic renal disease who had normal renal function before the planned conception, is accompanied with increased risk for both the mother and child.

A 22-year old unmarried healthy woman was admitted to the Swedish department with low fever, tiredness, SR 75 mm, positive uricult, but no urinary tract symptoms. Urinary tract infection was suspected and treatment was started with norfloxacin. Nevertheless, the urine culture proved to be negative. A few weeks later she had increasing trouble with stiff knee and shoulder joints and the left foot became swollen. The subfebrile status continued, and tonsillitis was suspected and diagnosed. V-penicillin and cefaklor treatment was applied. She was transferred to the infectious diseases ware, where fever was confirmed with leukocytosis (19 x 1 billion/1), C-reactive protein at 66 (normal value 10) mcg/ml, pronounced blood pressure increase (160/130 mm Hg), anemic signs, and pathological liver status with increased transaminases (ASAT 6.3-10.4 and ALAT 8.,8-16 ukat/1). ALP increased slightly to 6 ukat/1. The symptoms of weight loss indisposition, and muscles and joints aches, especially in foot ache continued. Collagen disease was suspected, and she was transferred to the internal medicine department. She regularly had tachycardia and high blood pressure. She had to use crutches for mobility because of the pain. S-albumin was 32 (normal 36- 50) g/l and S-hepatoglobin was 2.7 (normal value .4-1.8) g.l. Various others tests were normal. Ulnaris neuropathy was suspected on the left hand. Intensive blood pressure reducing combination treatment was started with 200 mg x 1 of metoprolol, 10 mg x 2 nifedipin, and 20 mg x 1 enalapril. The Desolett oral contraceptive (containing 30 mcg of ethinyl estradiol and 150 mcg of desogestrel) she had been taking for a few months were discontinued. Quick improvement of clinical and laboratory parameters followed. SR and leukocytosis became normal. The values of ALP, ASAT, and ALAT became normal some days later. She was discharged shortly thereafter, and blood pressure medication was gradually discontinued. In the 1940s there were reports about the hepatotoxic effects of synthetic estrogens followed by carbohydrate, lipid, and protein metabolism alterations. Jaundice has also been reported, and the Swedes have an ethnic susceptibility to it. The global incidence rate is 1/10.000 vs. 1/100 and 1/4000 in Sweden induced by high-dose OCs containing more than 50 mcg ethinyl estradiol, but with low-dose OCs this rate is much lower. Both estrogens and gestagens can increase blood pressure. A 1969 study reported that 22 young women developed arthritis, arthralgia, and myalgia after taking pills for 3- 12 months. Rheumatic symptoms were also recorded with pill use. Thus, it is very likely that OCs were responsible for the patient's symptoms, especially since her status rapidly improved after discontinuing them.

Urinary tract infections, in association with ureteral reflux or dysperistalsis, may lead to invasive renal parenchymal infection and residual scarring (reflux nephropathy). Such infections in infants are often not diagnosed during the acute phase. Late sequelae of reflux nephropathy include hypertension, proteinuria, or chronic renal failure. The latter may eventuate in the subset of patients with urinary tract infection and unilateral reflux extending to a solitary kidney or bilateral reflux. Proteinuria may herald the inexorable progression of glomerular sclerosis in patients destined to progress to end-stage renal disease, despite the absence of further recurrences of urinary tract infections. The mechanism of progression is probably similar to that occurring in other forms of chronic, diffuse parenchymal renal disease, which all have similar alterations in glomerular hemodynamics (an increase in glomerular capillary flow, pressure, and filtration). The consequent hyperfiltration per nephron may be related to the level of dietary protein intake or to some derivative of the protein load. Hyperfiltration appears to recapitulate the presumed renal hemodynamic response to the relatively high level of episodic meat consumption by paleolithic hunter-gatherers. A prudent therapeutic intervention in children with progressive reflux nephropathy may be a proportional reduction in protein intake.

A 1-page check-off form that can be used to evaluate a woman's risk factors for oral contraceptives, IUD or diaphragm and spermicide, and provide a permanent health record of the evaluation, has been revised to reflect lower-dose pills and new information. Each risk factor is assigned points in columns under each contraceptive method, so that a score of 10 suggests that a contraindication may exist against that method. Some of the changes for orals are lower scores for age 40, unless other risk factors co-exist, especially smoking. Liver disease, hepatitis and gall bladder disease were eliminated, but liver tumors, endometrial cancer and cholestatic jaundice of pregnancy were each given 10 points. Scores were altered slightly for chloasma, hemoglobinopathies, hypertension and diabetes. Scores for the diaphragm were lowered for pelvic relaxation risk but 5 points were introduced for history of urinary tract infection. For IUDs, multiple sexual partners and abnormal bleeding are added as risks.

We have performed coronary bypass grafting in 25 patients 80 years of age or more. The patients' preoperative conditions were characterized by recent myocardial infarction (16/25, or 64%), obesity (15/25, or 60%), hypertension (14/25, or 56%), and left ventricular dysfunction (21/25, or 84%). There were no deaths in the hospital or within 30 days of operation (0/25, or 0%). Postoperative complications occurred in five cases (20%). Complications were leg incision infection (2/25, or 8%), urinary tract infection (1/25, or 4%), stroke (1/25, or 4%), and transient neurologic deficit (1/25, or 4%). There were no instances of reoperation for bleeding, perioperative myocardial infarction, renal failure, pulmonary failure, intraaortic balloon pump use, or sternotomy infection in these patients. Eleven patients (44%) were hospitalized for fewer than 10 days after operation, and all but two (23/25, or 92%) were discharged within 20 days after operation. All patients were followed up, and survival and New York Heart Association functional class were determined. Cumulative survival rate was 94% at 1 year and 88% at 5 years. The cumulative percent survival rate with class I or II function was 92% at 1 year and 80% at 5 years. No patient had recurrent angina.

Renal injury associated with the intrarenal reflux (IRR) of urine that is either infected, under high pressure, or both, is a major cause of severe hypertension during childhood and adolescence and of chronic renal insufficiency in patients less than 30 years of age. Many, but not all, adolescent and adult patients with reflux nephropathy (RN) give a history of urinary tract infection (UTI) or unexplained fevers in infancy or early childhood, when the kidney is thought to be at greatest risk of injury. Although vesicoureteric reflux (VUR) is observed more commonly in infants than children with UTI, it is rare in uninfected patients at any age and should never be considered a normal finding during human development. Renal scarring may not be obvious in radiographic or radionuclear studies to medical management alone, no definite benefit of one over the other was observed, regardless of the grade of VUR. Moreover, progressive renal injury in scarred kidneys has been noted even after VUR had been corrected, when infection had been prevented, and while hypertension had been controlled satisfactorily. Focal glomerular sclerosis, a lesion found in patients with proteinuria and RN, has been identified not only in scarred kidneys, but also may be seen in contralateral, unscarred kidneys without VUR, which might suggest a humoral factor or, perhaps, a hyperfiltration phenomenon. RN is one of the most frequent causes of end-stage renal disease (ESRD) in children, adolescents, and young adults, which is potentially preventable. However, prevention will depend on early identification of patients at risk--infants and young children after the first UTI and siblings of patients with VUR--aggressive and effective treatment of UTI, minimizing intravesical pressure, and education of patients, parents, and physicians.

The purpose of this study was to define manifestations of autosomal dominant polycystic kidney disease (ADPKD) in older patients with the disease. Fifty-seven subjects age 50 years or more, who were at risk for having inherited the gene for ADPKD, were evaluated for renal size, hypertension, back and abdominal pain, symptoms consistent with urinary tract infection (UTI), hematuria, end-stage renal failure, and liver cysts. The diagnosis of ADPKD was made in 32 of the 57 at-risk subjects (56%). At the time of study, only one patient with the disease was asymptomatic and normotensive and denied any previous symptoms suggestive of the disease. Clinical manifestations of ADPKD in the 31 symptomatic patients were hypertension (69%), a history of back and abdominal pain (47%), symptoms consistent with UTI (41%), hematuria (31%), and end-stage renal failure (47%). Liver cysts were found in 44% of patients. No statistically significant differences in the frequency of any manifestations of ADPKD between men and women were found, although the frequency of symptoms consistent with UTI tended to be higher in women (53%) than in men (27%). Most patients developed symptoms after the age of 40 years. Notably, 31% of the older patients with ADPKD had normal serum creatinine levels. Thus, older subjects with kidney cysts who are at risk to have inherited the gene for ADPKD, should be considered to have the disease even in the presence of well-preserved kidney function. This observation may play an important role in assessing the prognosis of older subjects at risk who have bilateral renal cysts and in genetic counseling of their relatives.

The common childhood renal disorders in Nigeria are post-infectious acute glomerulonephritis (PIAGN), nephrotic syndrome, hypertension, congenital anomalies and urinary tract infection. Children with PIAGN often present with hypertension, circulatory overload and hypoalbuminaemia. Nephrotic syndrome is characterized by a paucity of minimal change and a poor prognosis. Posterior urethral valves and hydronephrosis are the most frequent congenital anomalies. Children with congenital anomalies present late with advanced disease. The commonest malignancy is nephroblastoma, but Burkitt's lymphoma of the kidney also occurs. Both acute and chronic renal failure present depressing and distressing clinical problems, with an aggressive course and a high morbidity and mortality. Poor socio-economy has adverse effects on the presentation, management and follow-up of Nigerian children with renal disorders.

The clinical course of 48 children (27 boys and 21 girls) with multicystic kidney dysplasia was analysed retrospectively. The patients were seen and treated at the Children's Hospital of Medical School Hannover between 1976 to 1989. There was no familial occurrence of the disease, yet in eight families various other renal diseases could be observed. In 20 patients the diagnosis of multicystic renal dysplasia was presumed by prenatal sonographic examination, in the other patients the diagnosis was established at the age between 1 day to 12 years. The first manifestations were palpable abdominal mass (n = 16), urinary tract infection (n = 4), casually because of a sonographic evaluation for other reasons (n = 4) and vomiting (n = 2). Associated malformations were found in 18 patients: cardiac malformations (n = 6), dysplasia of the other kidney (n = 5), ureter obstruction of the other kidney (n = 3), horseshoe kidney (n = 1) and others (n = 3). There was no hypertension and serum creatinine levels were normal in those children, who did not suffer from associated malformations of the other kidney. The multicystic kidney was removed operatively in 42 patients at the age of 3 days to 9.5 years (median 4 weeks). The prognosis of multicystic kidney dysplasia depends on associated renal and other malformations.

In order to study the effectiveness of unilateral nephrectomy as a treatment for chronic unilateral pyelonephritis, 15 consecutive patients who had undergone this operation were followed up. The patients had been operated on 8.9 years (mean) earlier. All of the 15 patients had had recurrent urinary tract infections prior to the operation, 11 of them had had pyelonephritis for between 1 and 19 (mean 6.7) years. One patient only had had a verified episode of urinary tract infection during the follow-up period. All 15 patients were hypertensive prior to the operation. At the time of follow-up, 7 patients were normotensive without drugs, and 2 were normotensive with a reduced dosage of antihypertensives. The mean systolic blood pressure went down from 180 to 150 mm Hg, and the mean diastolic pressure from 109 to 88 mm Hg. This operation can thus be recommended in selected cases of unilateral chronic pyelonephritis with hypertension.
