    Notes: Abstract We report a rare complication of of ritual circumcision in an 8-week-old boy. He presented 1 week after the procedure with reduced urine output, a grossly distended bladder and marked bilateral hydroureteronephrosis on ultrasonography. The acute partial urinary obstruction was due to the dressing which was applied after surgical removal of the foreskin and to oedema of the glans. He had abnormal renal function (creatinine 85 μmol/l, urea 8.5 mmol/l) and a hyperkalaemic metabolic acidosis with hyponatraemia (Na 127 mmol/l, K 6.9 mmol/l, HCO3 16 mmol/l), which were attributed to obstructive uropathy. Because of prolonged secondary bladder dysfunction he required urinary catheterisation for 1 week. There was significant post obstructive diuresis and parenteral fluid therapy was given for 7 days. Whilst urinary retention is a well recognised complication of circumcision, this is the first report of significant obstructive uropathy and renal impairment due to surgical excision of the foreskin.

    Notes: Monte Carlo computer simulations of monolayer adsorption of a gas on a solid surface are described in which the potential distribution method was used to directly calculate the adsorption isotherms. The systems studied were the two-dimensional, Lennard-Jones fluid and such a fluid in external potentials chosen to represent the interactions of the adsorbate molecules with exposed faces of an inert fcc crystal. The adsorption isotherms for the structured surfaces show a substantial influence of the surface corrugation upon the adsorption equilibria. The results demonstrate that the potential distribution method is a useful approach to studying adsorption equilibria.

    Notes: Abstract Laboratory studies of the pathophysiology of Henoch-Schönlein purpura (HSP) have become more numerous in recent years with the recognition of the disease's links with the mucosal immune system in general and IgA nephropathy in particular. There are weak genetic associations with C4 null phenotypes and with HLA B35 and DR4. Studies of plasma proteins in HSP patients show an increased IgA concentration, activation of the alternative pathway of complement and consumption of factor XIII. High molecular weight (polymeric) IgA has been detected in affected individuals, which some investigators have called “immune complexes”. Many patients synthesise an IgA rheumatoid factor in the acute phase, but other autoantibodies are largely absent. In vitro studies of lymphocytes from HSP patients have demonstrated an increased number of IgA-bearing and secreting B-cells, with altered T-cell regulation of antibody synthesis. While these observations point to immune dysregulation — primarily of IgA production — as a consistent feature of acute HSP, there is as yet insufficient information available to allow a consistent theory of pathogenesis to be formulated.

    Notes: Abstract   Fourteen children, aged between 5 and 17 years, with stable renal graft function and stable cyclosporin A (CSA) trough levels (Cmin) were studied. They had been taking CSA 12-hourly since their transplant 1.5–9 years previously, with the average dose of Neoral being 6.4 (range 4.4–8.4) mg/kg per day. CSA whole blood levels were measured at 0, 20, and 40 min, and at 1, 1.5, 2, 2.5, 3, 4, 6, and 8 h following the morning dose using the Abbott TDx fluorescence polarization immunoassay. The area under the concentration time curve (AUC), clearance adjusted for bioavailability (CL/F), and steady-state volume of distribution adjusted for bioavailability (Vss/F) were determined using model-independent pharmacokinetic analysis. Delay time (Tdel), peak concentration (Cmax), time to peak concentration (Tmax), and Cmin were also determined and correlated with AUC and other parameters. The Tdel in absorption varied from 0.3 to 1.6 (mean 0.73) h, resulting in a similarly variable time to Tmax of 1–2.4 h (mean 1.59). Tmax was related to the age of the patient (Tmax=0.027age+1.41, r 2=0.56, P〈0.005). The AUC showed good correlation with Cmax (Cmax=0.25AUC+423.32, r 2=0.96, P〈0.0005). Cmax appears to be a more-suitable measure of exposure to CSA than Cmin. Prediction of Tmax from the age of the child may help to overcome the problem of when to collect blood for peak levels.

    Notes: Abstract. Neonatal Bartter syndrome differs from the classical Bartter syndrome in the occurrence of antenatal presentation with polyhydramnios. Nephrocalcinosis and severe growth retardation are common sequelae. Indomethacin has been reported to improve linear growth, but its use in the early newborn period has been infrequently described. In this paper we report normal growth and development and the absence of nephrocalcinosis in an infant now aged 19 months with neonatal Bartter syndrome treated from day 3 of life with indomethacin. With early diagnosis and treatment with indomethacin plus adequate water, calories, and sodium, normal growth can be achieved and nephrocalcinosis may be prevented in children with neonatal Bartter syndrome.
