Experience with 1,25-dihydroxycholecalciferol therapy in undergoing hemodialysis patients with progressive vitamin D2-treated osteodystrophy.

Six long-term hemodialysis patients with progressive skeletal deterioration during long-term pharmacologic vitamin D2 therapy were treated for six to 12 months with oral 1,25-dihydroxycholecalciferol (1,25-(OH)2D3) to determine its therapeutic effectiveness in vitamin D2-unresponsive osteodystrophy. On bone biopsy, three of the patients had severe osteomalacia and three showed predominant osteitis fibrosa. Previous therapies, including phosphate binders and dialysis schedules, were maintained. The three patients with osteomalacia and the two with osteitis fibrosa showed clinical deterioration. There was no significant change in serum calcium, phosphate, alkaline phosphatase, bone densitometry, immunoreactive parathyroid hormone levels or bone histology. Roentgenograms showed multiple new fractures of ribs and femoral necks in the patients with osteomalacia and increased bone resorption in two of three patients with osteitis fibrosa. 1,25-(OH)2D3 dosage had to be decreased in all patients because of hypercalcemia with a mean tolerated dose of 0.22 microgram/day. In these patients, 1,25-(OH)2D3 was not effective therapy for progressive osteodystrophy unresponsive to pharmacologic vitamin D2.

Spurious hypocalcemia in hemodialysis patients after heparinization. In-vitro formation of calcium soaps.

Patients on long-term hemodialysis via arteriovenous fistula received heparin when the fistula needle was inserted, before a sample of blood was obtained for chemical analysis. The resultant release of lipoprotein lipase activity in vivo and continued lipolytic activity in vitro sometimes produced sufficient free fatty acid to precipitate calcium soaps. The consequent spurious hypocalcemia was most frequently observed when the patients had chylomicronemia. This cause of apparent hypocalcemia was eliminated either by immediate analyses of the blood samples or by obtaining samples before systemic heparinization.

Membranoproliferative glomerulonephritis type 1: comparison of natural history in children and adults.

Clinical, laboratory and pathological data on 46 patients (29 children and 17 adult) with Type 1 membranoproliferative glomerulonephritis (MPGN) were reviewed in order to compare the natural history of the disease in two age groups. The nephrotic syndrome was the most common presenting clinical feature in both age groups. Established renal failure at time of biopsy was seen in adult males only. All the adults males, but none of the women, were either dead or in renal failure after a mean duration of diseases of 17.7 months. In contrast 43% of the children (both sexes) were in renal failure after a mean duration of disease of 51.6 months. Statistical analysis disclosed that only up to 48 months was there a significant difference in survival between the two age groups (P less than .01). Beyond this time the difference was not statistically significant. The difference in behaviour of MPGN in the two age groups is similar to that observed in other glomerulonephropathies.

Results of 12 years' treatment of chronic renal failure by dialysis and transplantation.

The survival of 305 patients with chronic renal failure treated at the Vancouver General Hospital by centre and home peritoneal dialysis, centre and home hemodialysis and cadaver renal transplantation over a 12-year period was analysed. There was decreasing survival with age except in patients undergoing home dialysis. Hypertension and analgesic nephropathy as primary causes of renal disease were associated with a poor prognosis. Hence age and diagnosis appear to be two of the main determinants of survival. Cardiovascular disease was the commonest cause of death but seven deaths were due to dialysis dementia. The results compare favourably with other published statistics.

The efficacy of cefuroxime for the treatment of acute gonorrhoea in men.

This is a report on a clinical trial in which cefuroxime was used for treating 110 men with uncomplicated urethral gonorrhoea. Twenty-three men were given 1 g cefuroxime intramuscularly and 1 g probenecid orally, and 87 were treated with 1.5 g cefuroxime intramuscularly with 1 g probenecid orally. All 18 patients treated with 1 g cefuroxime and 1 g probenecid and seen at least once after treatment, were cured. Sixty-six (98.5%) of 67 patients treated with 1.5 g cefuroxime and 1 g probenecid and seen at least once after treatment, were cured. No side effects were reported. The high cure rates compared favourably with other antibiotics now in regular use and cefuroxime should be of great value especially for patients infected with beta-lactamase producing gonococci.

Oral talampicillin in the treatment of gonorrhoea.

Talampicillin was effective in eradicating the causitive organism in uncomplicated gonorrhoea, with only four treatment failures (1-6%) in 245 patients seen at least once after treatment. Symptoms, such as discharge, were seen in 61 patients at some stage after treatment but 31 of these cases were clear after one or two follow-up visits. The anitbiotic was well tolerated. One patient developed a maculopapular rash, penicillin allergy was reported in two patients, and a generalised itch (possibly penicillin allergy) in one further patient. A total of 241 out of 245 (98%) cases had the urethral gonococcus successfully eradicated with talampicillin. Talampicillin given in single doses appears to be an extremely good choice of antibiotic in the treatment of uncomplicated gonorrhoea in men.

Machiavellianism in patients and their children.

The role of the family in the development of Machiavellianism was examined in this study. High- and low-Machiavellian sixth graders played a bluffing game. Their parents completed Machiavellian belief measures. The Machiavellianism of fathers and mothers was positively related to their children's success at deceiving others but not at seeing through others' attempts at deception. In addition, fathers' Machiavellianism was positively related to their children's Machiavellian beliefs. These data support a modeling hypothesis for the development of Machiavellianism. Unexpectedly, the children's own behaviors and beliefs were unrelated. This pattern of results suggests that a child's manipulative behaviors and beliefs are learned separately and only become consistent over time.

Amoxycillin in the treatment of gonorrhoea.

A series of 162 patients with uncomplicated genital gonorrhoea was assessed after single-dose treatment with 3 g. amoxycillin. This seems to be an acceptable method of treatment, resulting in clearance rates in both male and female patients of 99 and 95% respectively at the first follow-up. The default rates on follow-up over a 4-week period are also shown.

Flucloxacillin in the treatment of infectious conditions in children.

A multi-centre study was carried out in 107 children with skin and soft-tissue infections (46) or upper respiratory tract infections (61) to assess the effectivness of flucloxacillin (125 mg. q.d.s. for 5 days). Swabs were taken from the lesion sites before and after treatment for bacteriological assessment and sensitivity of the isolated organisms. The clinical success rate achieved was 93% in skin and soft-tissue infections and 94% in upper respiratory tract infections and these results correlate closely with the bacteriological findings. The main causative organism in the skin and soft-tissue infections was Staph. aureus which was resistant to benzyl penicillin and to ampicillin in all but 2 cases. All strains proved sensitive to flucloxacillin. Minimal side-effects were reported and the syrup presentation was well accepted.
