    There is evidence to show that paraquat poisoning is alarmingly common in Malaysia. This paper reviews 30 cases of paraquat poisoning seen at the General Hospital, Kuala Lumpur from 1978 to 1979 inclusive. Preventive measures and management are discussed. It is felt that tighter legislation to control its use in agriculture should be implemented now.

    38 episodes of peritonitis in 28 patients were recorded among 97 patients undergoing a total of 159 peritoneal dialysis at the Nephrology Unit, General Hospital, Kuala Lumpur between November 1979 to June 1980. Of these only 14 episodes were associated with a positive bacterial culture. Organism of the Moraxella-Acinetobacter group were responsible in 8 episodes. There were 16 positive cultures in patients who had no clinical evidence of peritonitis. The interpretation of bacterial peritonitis in patients undergoing peritoneal dialysis must be made on the basis of clinical findings and bacteriological reports.

    Creatinine clearance is calculated from 24 hour urine creatinine excretion. This method of measuring creatinine clearance is cumbersome. Many formulae have been proposed as an alternative method of obtaining predicted creatinine clearance and they have all shown satisfactory results. From our study using 4 formulae, the correlation coefficient using these formulae rangedfrom 0.71 - 0.75. The correlation clearance was even better at > 0.90. We therefore advocate the routine use of these formulae for predicting creatinine clearance by clinicians.

    From a total of 163 renal biopsies there were 12 cases (9.1%) of IgA nephropathy. All of them presented with symptomatic or asymptomatic proteinuria and/or haematuria. The pattern of disease here generally conforms to reports elsewhere. However in contrast it appears to be common in both sexes and the clinical course tends to be more severe In males. The absence of IgG In the glomeruli on immunoffourescence was an unexpected finding. The presence of hypertension, renal insufficiency and glomerulo·interstitial scarring seem to indicate poorer prognosis. There is no known effective treatment.

    Two-hundred and sixty-five patients with asymptomatic proteinuria and/or haematuria were studied at the Department of Medicine, Universiti Kebangsaan Malaysia and Department of Nephrology, General Hospital Kuala Lumpur. They represented 25.4% of all the renal biopsies performed during the period 1980-88. All the three races were affected with 71.3% occurring between the ages of 20-39 years and 41.1% were detected during routine medical examination. Excluding those patients with lupus nephritis, IgA nephropathy was the commonest histological diagnosis (51.7%). The presence of severe and advanced histological changes in a significant number of biopsies emphasises the need for more effective screening and early referral of this group of patients.

    Between 1980-1986, 219 renal biopsies were performed on patients with lupus nephritis (LN) presenting at the General Hospital, Kuala Lumpur. There were 172 (78.5%) females and 47 (21.5%) males. The ethnic distribution of 48.4% Malays, 46.1% Chinese and 5.5% Indians reflected their proportional composition in the general population. Peak incidence (40.6%) of cases occurred in the third decade of life (20-29 group) followed by 26.5% and 20.1% in the second and fourth decades respectively. The median age was 24 for females and 27 for males. In both sexes, nephrotic syndrome was the commonest mode of presentation (62.2%) followed by proteinuria (20.5%). Acute oliguric renal failure occurred in 11 patients (5%) and 8 of these showed crescentic glomerulonephritis with more than 50% crescents. The commonest histological picture was diffuse proliferative LN (WHO Stage IV-44.7%) which included 70% (19/27) of those with crescentic disease. This was followed by membranous LN (28.8%) of which 6 (all males) had crescentic disease. 7 (12.3%) of our patients had crescentic nephritis with a female to male distribution of 14: 13, suggesting either more aggressive disease or delayed diagnosis in males.
    Key words - Renal biopsies, lupus nephritis, nephrotic syndrome, proteinuria.
