The analysis of urinary proteins and their identification are discussed, particularly in regard to the technique of sodium dodecyl sulphate electrophoresis in polyacrylamide gradient gels. Urine collection, storage and preparation are evaluated, especially in regard to problems connected with concentration and dialysis of such samples. The instrumental approach to sodium dodecyl sulphate polyacrylamide gel electrophoresis represented by the Phast System appears to be particularly valuable in routine clinical analysis of urine specimens, since no sample pretreatment is required. The following types of proteinurias are evaluated: (a) orthostatic proteinurias; (b) post-renal proteinurias; (c) Bence-Jones proteinuria; (d) lower and upper urinary tract infection (cystitis and pyelonephritis) and (e) diabetes mellitus proteinurias.

A 1-page check-off form that can be used to evaluate a woman's risk factors for oral contraceptives, IUD or diaphragm and spermicide, and provide a permanent health record of the evaluation, has been revised to reflect lower-dose pills and new information. Each risk factor is assigned points in columns under each contraceptive method, so that a score of 10 suggests that a contraindication may exist against that method. Some of the changes for orals are lower scores for age 40, unless other risk factors co-exist, especially smoking. Liver disease, hepatitis and gall bladder disease were eliminated, but liver tumors, endometrial cancer and cholestatic jaundice of pregnancy were each given 10 points. Scores were altered slightly for chloasma, hemoglobinopathies, hypertension and diabetes. Scores for the diaphragm were lowered for pelvic relaxation risk but 5 points were introduced for history of urinary tract infection. For IUDs, multiple sexual partners and abnormal bleeding are added as risks.

The effectiveness of antibiotic prophylaxis was evaluated in the immediate postoperative period of renal transplantation (RT). Before RT, the patients were randomly assigned to one of the following groups: 1) cefotaxime (intravenous infusion of 1 g one hour before the operation). 2) Ceftriaxone (1 g i.v. given in a similar way). 3) Control (without antibiotics). Patients who required antibiotic therapy during the first 3 postoperative weeks were excluded. 20 recipients of cadaveric renal grafts were included in each group. There were 39 males and 21 females with a mean age of 39.9 years. One patient from the cefotaxime group (5%), 2 from the ceftriaxone group (10%) and 2 from the control group (10%) developed infection of the surgical wound, all due to grampositive organisms. 19 patients had urinary tract infections: 7 from the control group (35%), 7 from the cefotaxime group (35%), and 5 from the ceftriaxone group (25%). The development of wound infection was not correlated with urea, creatinine, hemoglobin or total protein levels, or with urinary tract infection or fistula, diabetes or fever. The mean packed red cell volume of the patients who developed wound infection was 24.7 +/- 1.2 vs 28.6 +/- 6.6 in those who did not (p less than 0.01). All patients with visible hematoma and 3 of 10 with perirenal blood collection had wound infection. It was concluded that antibiotic prophylaxis for renal transplantation was useless in our patients.

The tendency of indwelling catheters to cause urinary tract infection was evaluated in a randomised clinical study of 223 patients. A Foley catheter coated with silver alloy on both inner and outer surfaces was used in 60 patients; 60 others received a Teflonised latex Foley's catheter and the remaining 103 patients were excluded because of antibiotic treatment, diabetes, etc. There was a statistically significant difference in the incidence of catheter-associated bacteriuria (greater than 10(5) organisms/ml) in the 2 groups after 6 days' catheterisation: 6 patients with the silver coated catheter developed bacteriuria compared with 22 who had the Teflonised latex catheter. This suggests that the silver impregnated urethral catheters reduce the incidence of catheter-associated urinary tract infection.

The clinical manifestations of septicemic melioidosis and other bacterial septicemia were studied at Srinagarind Hospital, Khon Kaen University. Forty-three cases of septicemic melioidosis and 68 non-melioidosis septicemia cases were analysed. By univariate analysis, the following clinical features are associated with septicemic melioidosis: male patients; age below 45 years; underlying diabetes mellitus or renal failure; pulmonary infection, impending respiratory failure and multiorgan involvement, while abdominal pain and urinary tract infection were more common in non-melioidosis septicemia. By using discriminant analysis and logistic regression, 3 features (diabetes mellitus, multiorgan involvement, and no abdominal pain or pulmonary infection) could discriminate the two groups with the accuracy of more than 85 per cent.

With the intention of reducing the abortion, preterm delivery and perinatal mortality caused by the genito urinary infection (GUI) we attempt to identify the risk factors and with those make a diagnostic test, that permits detection and prediction of GUI during gestation period. Morbidity records that suggests alterations of immune response were studied in a group of 165 pregnant women that presented GUI and were compared with 86 pregnant women without GUI. As risk antecedents, we found: spontaneous abortions of second trimester 42.4% (study group) and 6.9% (control group) (p < 0.01), repeated vaginitis 31.5% and 2.3% (p < 0.01) urinary tract infection (UTI) 29.7% and 6.92% (p < 0.01), preterm deliveries 17.6% and 3.52% (p < 0.01), puerperal infection 9.12% and 0.0% (p < 0.05), familiar diabetes 21.2% and 8.12% (p < 0.05). Psychiatric pathology 12.72 and 3.5% (p < 0.05), typhoid fever 12.1% and 3.5% (p < 0.05) and surgical infections 16.4% and 8.12% (p < 0.1). A score was elaborated assigning 1/2 point to: puerperal infections, familiar diabetes, psychiatric pathology, typhoid fever and surgical infections; 1 point to: abortion, vaginitis, UTI and preterm delivery and 2 points to: repeated abortion, UTI and preterm delivery. Patients were divided in multiparous and primiparas. In multiparous with 1 or more points we found: sensitivity 75.3%, specificity 81%, positive predictive value 89.3%, negative predictive value 60.7% and accuracy 77.1%. In primiparas with 1/2 or more points we found: sensitivity 61.8%, specificity 70.5%, positive predictive value 78.3%, negative predictive value 51.7% and accuracy 65%.

The quality of prenatal care offered in health centers (HC) and in the hospital (H) have been compared. Two samples were evaluated. One consisted of 476 pregnant women seen in HC and another of 213 who were seen in H. Five out of the 22 selected markers did not show differences in both levels (date of delivery; weight gain in g/week; measurement of uterine weight and height; and hypertension detection). Ten markers were better fulfilled in H than in HC (obstetrical formula; gynecological examination, fetal heart beats and edema examination; detection of diabetes, urinary tract infection and anemia). By contrast, there were seven markers that were better fulfilled in HC (serological tests for syphilis and hepatitis B; treatment of urinary tract infection and anemia; and compliance with follow up). The better fulfillment of the markers in H might be due to the recent inclusion of prenatal care programs in HC. The fact that in the first level of care the controls are earlier and more frequent shows that this level facilitates the access of pregnant women to services and their follow up.

Five hundred and thirty-three patients in the Oxford renal unit were reviewed to determine the incidence of infection in one calendar year. There were 310 patients who received dialysis, 53 with acute renal failure and 211 with chronic renal disease. Renal transplant patients were not included in the study. Apart from infections related to dialysis access, patients on maintenance haemodialysis or continuous ambulatory peritoneal dialysis developed few serious infections unless they had another disease causing suppression of immune function. A total of 97 urinary tract infections were seen; in patients with chronic renal disease not receiving dialysis the incidence of urinary tract infection was significantly associated with increasing uraemia, with diabetes, and with treatment with azathioprine or cyclophosphamide. In patients with acute renal failure, Gram-negative septicaemia and fungal infections were important causes of morbidity and mortality, but cardiovascular disease caused 42 per cent of the deaths unlike results from other series where sepsis has been by far the commonest cause of death.

The postoperative duration of pyuria was studied in 35 patients who underwent transurethral resection of the prostate (TUR-P). The average postoperative duration of pyuria was 58.0 +/- 23.6 days. The age over 70 years, preoperative indwelling of urethral catheter and the preoperative urinary tract infection did not make the duration of pyuria longer. The volume of resected prostatic tissue over 20 g and the existence of diabetes mellitus make it significantly longer. It is effective and safe to use a low-dose antibacterial agent such as NFLX which has a broad spectrum and hardly develops bacterial resistance after TUR-P. It is suggested unnecessary to change the anti-bacterial agent even when pyuria continues.

Our experience with group C streptococcal infection over the past 15 years demonstrates an important and emerging role for this hemolytic organism as an opportunistic and nosocomial pathogen. Significant risk factors in this predominantly male population included chronic cardiopulmonary disease, diabetes, malignancy, and alcoholism. Bacteremia occurred in 74% of cases seen in our series. Nosocomial acquisition of infection was observed in 26%, and infection was frequently polymicrobial in nature with gram-negative enteric bacilli isolated most commonly along with group C streptococci. We observed a broad spectrum of infections including puerperal sepsis, pleuropulmonary infections, skin and soft-tissue infection, central nervous system infection, endocarditis, urinary tract infection, and pharyngeal infections. Several cases of bacteremia of unknown source were observed in neutropenic patients with underlying leukemia. New syndromes of infection due to group C streptococci observed in our series included intra-abdominal abscess, epidural abscess, and dialysis-associated infection. Response to therapy and outcome was related to the underlying disease. While the literature suggests that patients with group C endocarditis respond better to synergistic penicillin-aminoglycoside regimens, patient numbers are too small to draw definite conclusions. The clinical significance of antibiotic tolerant group C streptococci remains uncertain. In patients with serious group C infections including endocarditis, meningitis, septic arthritis, or bacteremia in neutropenic hosts, we advocate the initial use of cell-wall-acting agents in combination with an aminoglycoside.
