A study group of 623 employed Swiss women aged 30-49 years showing objective evidence of intake of phenacetin-containing analgesics, and a control group of 621 comparable women showing no such intake, were observed for 4 years (1969-72) for laboratory evidence of urorenal disorders. In both study and control groups morbidity was low. There was no difference between the study and control groups with respect to subsequent proteinuria, bacteriuria, and haematuria. The 4-year incidence of low urine specific gravity after overhight thirsting was significantly higher in the study group than in the control group (3-8% v. 0-8%) and the incidence of raised serum-creatinine was also significantly higher in the study group (2-9% v. 0-4%). However, when the study group was further subdivided into a sub-group showing evidence of high intake of phenacetincontaining analgesics and one showing low intake, only the high-intake subgroup had an incidence of raised serum-creatinine (5-4%) significantly higher than the control group (0-4%), whereas the low-intake subgroup had an incidence (0-4%) similar to the control group.

Urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG) was shown to be reproducible in random urine specimens when expressed as the ratio of NAG to milligrams of urinary creatinine. The enzyme/creatinine ratio in 815 healthy people was relatively constant throughout childhood and adult life except for the first two years after birth and in individuals 56 years or greater. High ratios in the young children may be explained by low urinary creatinine excretion probably related to small body mass and reduced glomerular filtration rate at this age. The ratio was increased in adult uremic patients and children and adults with a variety of neurologic and obstructive lesions of the voiding mechanism. The presence of bacteriuria did not appear to increase the ratio. Significant enzymuria (greater than 2 SD above the mean for age and sex) was detected in 38 of 81 children with well-characterized renal disease. Among patients with predominantly glomerular disorders there was a close relationship between activity of the disease and enzymuria. In patients with tubulointerstitial disease enzymuria was frequent even in the absence of proteinuria. One of the highest enzyme/creatinine ratios was observed in a child with cystinosis. These studies indicate that NAG enzymuria is a sensitive indicator of activity of renal disease and may prove to be a suitable screening test for significant renal disease or injury in childhood.

Voided urines of 53,000 white and 9,3000 black cigarette smokers and nonsmokers were studied. Proteinuria was found to be commoner in smokers of both races and sexes. Heavy smokers showed proteinuria more frequently than light smokers. Of eight possible explanatory variables, one, alcohol consumption history, showed some interrelationship in that the smoking status-proteinuria association disappeared among heavy drinkers. Stopping smoking was not associated with a relative decline in proteinuria prevalence. Proteinuria associated with smoking did not appear to be indicative of more serious renal disease. There was a smoker-nonsmoker difference in urine glucose response to oral glucose challenge, apparently explained by higher average 1-hour serum glucose values for smokers, of unknown mechanism but partially explained by differences in alcohol usage. Hematuria, bacteriuria, and high urine acidity tended to be more prevalent in smokers, though these relationships were not consistently significant.

The relationship between Staphylococcus aureus bacteremia and bacteriuria was studied over a five year period in three hospitals. In a Veterans Administration Hospital, 59 patients with Staph, aureus bacteremia had a urine culture within 48 hours of a positive blood culture. In 16 of 59 (27 per cent), greater than 10(5) Staph. aureus was recovered from the urine in pure culture. Six of these patients had apparent primary staphylococcal urinary tract infection. Clinical and laboratory parameters in the patients with staphylococcal bacteremia and bacteriuria were compared with those in 31 patients with staphylococcal bacteremia and sterile urine cultures. The two groups differed only in the more frequent occurrence of pyuria and proteinuria in the bacteriuric patients. In two other hospitals, staphylococcal bacteriuria occurred in 7 per cent of patients with Staph. aureus bacteremia and in 13 per cent of cases of staphylococcal endocarditis. Review of autopsy records for 33 patients who died within one month of their bacteremia failed to show a correlation between bacteriuria and the presence of renal abscess. Staphylococcal bacteriuria is a frequent and unexplained concomitant of Staph. aureus bactremia.

A study group of originally 623 employed women of Northwestern Switzerland who were aged 30 to 49 yr and showing objective evidence of intake of phenacetin-containing analgesics, and a control group of 621 comparable women showing no such intake, were examined in 1968 and followed-up five times from 1969 to 1975 for laboratory evidence of urorenal disorders. Mortality was higher in the study group, with 21 deaths, compared to the control group, with 5 deaths, and was higher than expected in a comparative population in Switzerland (P less than or equal to 0.05). In both study and control groups, morbidity was low. There was no difference between the study and control groups with respect to subsequent proteinuria and hematuria. The seven-year incidence of low urine specific gravity after overnight thirsting was higher in the study group than in the control group (2.9% vs. 1.0%), and the incidence of raised serum creatinine was also significantly higher in the study group (2.9% vs. 0%). However, when the study group was further subdivided into a subgroup showing evidence of high intake of phenacetin-containing analgesics and one showing low-intake, only the high-intake subgroup had an incidence of raised serum creatinine concentrations (5.3%), significantly higher than the control group (0%), whereas the low-intake subgroup had an incidence (0.4%) similar to the control group. Also the high-intake subgroup showed significantly higher rates of bacteriuria than the controls (P less than or equal to 0.004).

A clinical epidemiological study was conducted to determine the association, if any, between the incidence of urinary schistosomiasis and urinary tract infection. The urinary excretion of protein and cells was also studied. Data was collected from 2 rural Nigerian communities--1 with a low level of endemic urinary schistosomiasis and the other with a high level. Midstream urine specimens were collected from the 2 populations. The laboratory procedures are described and the findings are presented in detailed tables. Proteinuria, haematuria, pyuria and bacteriuria were found to occur at significantly higher levels in the area of high than low schistosomiasis endemicity.

Radiologic findings are reported from 2 communities, 1 with high and the other with low endemicity of urinary schistosomiasis, of Ibadan. After studying the 2 rural communities with varying endemicities of urinary schistosomiasis by total cross-sectional population survey, a stratified sample was obtained using defined criteria (all cases of proteinuria of 100 mg%; all cases of diastolic blood pressure of 90 mm or greater; all cases with significant bacteriuria; 20% of cases with history of nocturia; and age-selected trace and absent proteinuria for 20% of cases). Plain X-ray abdomen and intravenous pyelogram were carried out on this defined sample population. Findings on plain abdominal X-ray, using the usual parameters of psoas and kidney shadows in the Nigerian, indicated that the 2 communities studied were similar, but urinary calculi and urinary tract distortion were significantly more prominent in the community with the higher endemicity of urinary schistosomiasis. X-rays are not included in the text, instead tabular information on the morphology of renal areas is presented.

Pyuria, proteinuria and haematuria have been shown to be unreliable parameters for the diagnosis of bacteriuria in 171 children with 455 recurrences of chronic urinary tract infection. Bacteriuria caused haematuria in 5%, proteinuria in 18% and even pyuria in only 47% of all instances. Pyuria has been also found in 11% of sterile urines. The incidence of pyuria increases with the age of the children and depends on the type of the organisms, but the latter was true mainly in children with obstructive lesions of the urinary tract. Children with repeated proteinuria during follow-up tend to have a higher incidence of pathologic findings on the i.v.-pyelogram.

Forty-two of 369 athletes were found to have a positive Occultest on the first urine sample voided following athletic competition. This positive reaction could be due to the presence of either myoglobin or haemoglobin. The Occultest was most often positive in competitors in the longer duration events such as the marathon. Twenty-six of these 42 specimens with a positive Occultest contained over 10 red cells per mm3. The urine samples were also examined for white cells, casts, bacteriuria and the concentration of urea, creatinine, electrolytes and protein. Proteinuria was a frequent finding and increased with the severity of the exertion.

Proteinuria has been analysed in 334 maturity-onset diabetics and 80 matched controls. Proteinuria measured in the recumbent position exceeded 100 mug/min in 53% of the diabetic population. The percentage of excessive proteinuria increased with duration of the disease. Sex and age had no influence. Out of 55 first year diabetics, 49% had abnormal quantitative proteinuria; this is in contrast to 76 longterm diabetics (over 12 years) of whom 38% had proteinuria under 100 mug/min. Electrophoresis and immuno-electrophoresis showed a glomerular pattern in 40%, a tubular pattern in 15% and a mixed pattern in 8% of all the diabetics. 32% of the diabetics with quantitatively normal proteinuria were abnormal qualitatively, and this may be the first manifestation of diabetic nephropathy. Thirty-eight other patients had a normal electrophoretic pattern in spite of increased proteinuria. Proteinuria levels were significantly associated with hematuria, bacteriuria and reduced GFR, but not with leukocyturia, insulin dependence and hypertension. Upright position increased the proteinuria to a greater degree amongst the patients with normal proteinuria. We discuss the role of increased filtration pressure and glomerular permeability in modifying proteinuria in diabetes. Sensitive quantitative and qualitative proteinuria determinations are important tools both in early diagnosis of diabetic nephropathy in clinical practice and in epidemiological studies.
