Hypertensive emergencies of 10 children with renal hypertension were analysed. Cause of renal disease are chronic renal failure in three, acute renal failure in three, hemolytic uremic syndrome in two, acute post streptococcal glomerulonephritis in one, and renal arterial stenosis in a further patient. Therapy should be started early in the course of the hypertensive emergency, first symptoms are headache and vomiting. Drug of first choice is diazoxide (3-5-(8)mg/kg i.v.). Three patients developed transitory hyperglycemia after repeated injections of diazoxide.

The in vitro activity of doxycycline and minocycline (Klinomycin) was determined by serial dilution test in 100 strains of E. coli, 101 strains of enterobacter, 91 tetracycline-sensitive and 52 tetracycline-resistant strains of staphylococci. Only staphylococci were more sensitive against minocycline than against doxycycline whereas other species showed nearly the same sensitivity against both antibiotics. After i.v. infusion of 200 mg minocycline (during 1 h) mean serum levels fell from 3.5 mug/ml to 0.6 mug/ml (after 24 h). Half-life was calculated as 15.7 h, urine recovery as 5.9%. After oral application of 200 mg minocycline serum level peaks were 2.7 mug/ml, serum levels after 24 h 0.7 mug/ml. At repeated administrations daily dosage of 100 mg was too low of 200 mg sufficient to obtain the same serum levels as after the initial dose of 200 mg. CSF levels after oral administration of 0.4 g minocycline were 0.74 +/- 0.09 mug/ml (in serum at the same time 2.2 +/- 0.2 mug/ml). Half-life of minocycline in chronic renal failure (7 adult patients) was not prolonged (15--20 h). Minocycline is especially suitable for treatment of infections of unknown bacterial origin (including such caused by staphylococci). I.v. infusion is indicated only in unconscious or vomiting patients.

In seven patients with chronic renal failure in an advanced stage 17 episodes of upper abdominal pain, hypertension, vomiting and (in some of them) coma occurred during peritoneal dialysis with sorbitol-containing dialysate. The signs recurred in some of the patients but did not when glucose-containing dialysate of otherwise identical composition was used. Very high levels of sorbitol in CSF and serum were measured in the comatose patients. The precipitating factor is probably a reduced metabolic breakdown of sorbitol in renal failure with preferential intracellular deposition of sorbitol and subsequent cellular oedema. To avoid this dangerous reaction it is necessary to use glucose instead of sorbitol in peritoneal dialysates, despite the technical problems of sterilisation. Where this is not possible, glucose should be added in order to reduce the sorbitol concentration in the dialysate to less than 15g/l.

Seventy-nine patients of end stage renal disease (ESRD) on maintenance haemodialysis were studied. Most of the cases were in their prime of life. The disease was equally common in both sexes and all ethnic groups. Chronic glomerulonephritis was the commonest cause followed by diabetes mellitus. Hypertension was the commonest associated illness. All patients were screened for hepatitis B surface antigen and antibody and those found negative were vaccinated. A-V fistula in the upper extremity was used as the vascular access in 93% cases. In 68% cases dialyzer was reused without any ill effect. Amongst the complications observed, hypotension was seen in 65%, psychological disorders in 52%, followed by nausea, vomiting, itching and cramps. Technical complications were related to A-V fistula in 45% cases. Forty three percent patients were maintained without blood transfusion and 88% showed improvement in their quality of life.

In children with chronic renal failure (CRF) anorexia, nausea, and vomiting are common yet poorly understood symptoms. We studied oesophageal and gastric motor function in 12 children (age 7 months-6.8 years) with severe CRF not undergoing dialysis who had persistent anorexia and vomiting. Eight of 12 patients had significant gastro-oesophageal reflux (reflux index 5.2% to 21.9%, mean 11.3%; controls < 5%), 7/10 had altered gastric half emptying times (T1/2) for 5% glucose or milk (glucose meal--controls: 8-14 min, two CRF patients: 18-25 min; milk meal--controls: 48-72 min, five CRF patients 27, 28, 82, 83, and 110 min). Gastric antral electrical control activity was abnormal in 6/11 patients, with different types of gastric dysrhythmias whereas the remainder and controls showed a regular dominant frequency of 0.05 Hz. In 7/9 patients fasting serum gastrin concentration was raised (53 to > 400, mean 168 pmol/l, controls < 40 pmol/l). All CRF patients with anorexia and vomiting had one or more disorder of foregut motility. The nature and variety of the motor disorders and the raised concentrations of circulating gastrin suggest that the normal environment generated by CRF affects the function of the smooth muscle of the foregut.

Since August, 1984 renal replacement therapy with haemodialysis, peritoneal dialysis and renal transplant has been carried out regularly at the renal unit of the Kenyatta National Hospital (KNH). Various nutritional disturbances have been met. Nausea, vomiting and anorexia have been noticed frequently particularly in those on intermittent peritoneal dialysis (IPD). The same problems were experienced in those few patients who were on continuous ambulatory peritoneal dialysis (CAPD). The patients were usually malnourished, the malnutrition being of protein-calorie type. At the start of the programme of renal replacement therapy in 1984, the problems of poor nutrition were worse but are currently improving. At the moment our patients with chronic renal failure (CRF) and end stage renal disease (ESRD) on dialysis are scattered all over the medical and paediatric wards at KNH. This has impeded the smooth surveillance of patients' diets by the few available nutritionists. The review of our performance from 1984-1988 on the nutritional status of patients with CRF and ESRD is an attempt to create a normal dietary cover for patients with the above problems.

Renal failure in itself generates a state of malnutrition, due to three main causes: inadequate ingestion (anorexia, vomiting or diet insufficiencies), the existence of catabolic factors (proteins, acidosis, PTH) and extrarenal depuration (which provokes a lack of amino acids and vitamins). Artificial nutrition constitutes a series of measures that can be adopted to act upon each of the above causes. Adequate ingestion compared to inadequate ingestion can be performed orally (especially in chronic renal failure) by parenteral administration (preferable in acute renal failure) and enteral administration (complementary in both cases). The quantity and quality of adequate nutrients is non-dependent on the method of administration; 500 ml, of water should be administered plus diuresis, plus loss from other tracts; the mineral intake of sodium, potassium and phosphorus should be restricted; in the case of vitamins, these should be administered, especially the B and D complexes; there should be sufficient calories to constitute a hypercaloric diet (from 30-50 kg/day), at least 50% in the form of carbohydrates (hypertonic glucose, if administered intravenously, and dextrinolmaltose or starch if administered through the digestive tract) and at least 40% in the form of lipids (preferably of vegetable origin, rich in non-saturated fatty acids); proteins are the mainstay of nutrition in renal failure; thus, with a normal renal function or in dialysis, a dose of 1 g/kg/day is recommended; in chronic renal failure, 0.5 g/kg/day; in cases of renal failure not on dialysis, 0.3 g/kg/day, supplemented by essential amino acids or cetoacids (the effectiveness of the latter is still in dispute).(ABSTRACT TRUNCATED AT 250 WORDS)

We did a double blind, crossover, prospective study comparing bicarbonate and acetate containing solutions in haemodialysis. Thirty stable patients with end stage renal disease on maintenance haemodialysis while awaiting a renal transplant were each studied on three dialysis with acetate and three with bicarbonate. Nine patients developed symptoms like headache, nausea, vomiting, giddiness, and malaise and developed hypotension during acetate dialysis and three patients during bicarbonate dialysis. There were symptoms during 16.66% of acetate dialysis sessions and 5.55% of bicarbonate dialysis sessions. (P less than 0.05). There was a statistically significant decrease in PaO2 and PaCO2 on acetate dialysis at 30 minutes after initiation of dialysis. There was no significant difference in weight loss on dialysis, or in blood pressure and correction of acidosis. We conclude that bicarbonate dialysis is better tolerated, but acetate intolerance is not a major problem since we use small surface area dialysers (0.8 M2).

Twelve children with end stage renal disease requiring dialysis received enteral feedings via nasogastric (NG) or gastrostomy (G) tube between 1984 and 1989 for provision of adequate nutrition. Records were reviewed for frequency and types of complications seen. Six patients, ages 1 week to 16 months received NG feedings for a total of 32 months. Complications included persistent vomiting with recurrent aspiration (2), persistent vomiting with peritoneal dialysis (PD) exit site leak (1), sinusitis (1), and refusal to continue NG feeds because of patient/parental anxiety (1). Three of the 6 were changed to G tube feedings after 2 days to 3 months. The complication rate was 1 per 6.4 patient months. Nine patients, ages 4 days to 11 years, received G tube feedings for 64 months. The complication rate was similar, 1 per 7.1 months. Complications were PD fluid leak around G tube exit site (1), G tube infection (2), G tube obstruction requiring tube replacement (3), tube migration producing intestinal obstruction (1), and gastrocutaneous fistula (2). Both methods were associated with similar complication rates, although somewhat different types of complications were seen. The young dialysis patient may have certain unique risks in addition to the complications generally associated with enteral feedings.

Tribal enemas obtained from traditional healers are used widely in Southern Africa for a variety of indications. Inclusion of injurious substances such as potassium dichromate may cause serious colonic and renal complications. Nine such patients, in seven of whom chromate use was confirmed, presented after a mean delay of 7.3 days. All patients had bloody diarrhoea and vomiting and three underwent major colonic resection, requiring a total of ten procedures. One patient suffered mechanical perforation of the rectum, with subsequent necrotizing fasciitis, necessitating rectal excision. Eight patients had acute renal failure and seven required dialysis. One patient died. At follow-up one patient has chronic renal failure and only three are completely well. Although local medical practitioners are aware of the problem, the challenge of preventing harmful cultural practices remains.
