Information on the incidence and nature of the causative organisms in the infected tissues of patients with diabetic gangrene is scanty. Studies in which material for culture was obtained from the presenting lesion reveal multiple organisms in host isolates. No data are available regarding the bacterial flora of the deep infected tissue itself, uncontaminated by surface organisms. In this investigation 58 specimens from 52 patients were obtained utilizing aerobic and anaerobic culture techniques. In the surgical theater, material was obtained from the infected deep tissues using careful aseptic dissection techniques. All patients had been on antibiotic therapy from 2 to 10 days before the study. An average of 2.3 organisms per specimen was found. The predominant organisms were Proteus sp., Enterococcus, Staphylococcus aureus, and other enterobacteriacae in that order. Anaerobes were isolated in 27 per cent of cases, but never as the only organism. Prior antibiotic therapy did not eradicate infection in infected diabetic gangrene.

Herein we review 26 cases of perinephric abscess, analyzed according to incidence, etiology, laboratory findings, signs and symptoms, diagnosis, radiographic findings, operative procedures, mortality and associated diseases. Of the abscess cultures 67 per cent were gram-negative organisms, most commonly Proteus, and 76 per cent of the abscesses were directly attributable to renal causes, mainly nephrolithiasis. Diabetes mellitus occurred in only 3 of the 26 cases.

A clinical and roentgenographic analysis of 13 patients with pathologically proved xanthogranulomatous pyelonephritis (X-P) has demonstrated that many previously accepted truisms associated with this disease may not be valid. As a result of this study it is suggested that X-P: 1. Does have a prominant female distribution. 2. May arise relatively acutely. 3. Can be associated with a well-functioning kidney. 4. May destroy the kidney and collecting system. 5. Does not demonstrate neovascularity. 6. Can be distinguished angiographically from hypernephroma. 7. May be associated with diabetes. Other important facts were again observed: 1. X-P is still often associated with staghorn calculi and urinary tract obstruction. 2. Proteus mirabilis is the main offending organism.

Over a period of 6 years 192 cases of urosepsis have been recorded and managed in our urological department. In almost all cases (97%) the primary focus of infection was the urinary tract and the responsible microorganisms were Gram-negative rods, in order Enterobacter, B. Proteus, E. Coli, Klebsiella and others. Clinical features were dominated by symptoms related to failure or insufficiency of end organs (fever, hypotension, oliguria, mental disorders, respiratory distress etc.). Bacteremia was diagnosed with an incidence of 66%, septic shock 12% and MSOF 20%. Negative bacteriological tests do not rule out the diagnosis of systemic infection. Risk factors are considered advanced age, uremia, diabetes, malnutrition and extensive surgery.

125 hospitalized patients (56 men and 69 women) suffering from urinary tract infection (UTI) and 15 women with endometritis or pelvic inflammatory disease were treated with ofloxacin 6 mg/kg/d i.v. divided into 2 doses. Two thirds of the patients were switched to oral ofloxacin using the same dose regimen after 4 days. The median duration of treatment was 10 days. 98 patients were evaluable for efficacy: 45 had complicated lower UTI, 32 had upper UTI (75% of them with complications), 13 had endometritis and 8 an uncomplicated lower UTI. The most frequent complications of UTI were: obstruction (n = 27), indwelling catheters (n = 23), urinary concrements (n = 12), residual urine (n = 8) and a neurogenic bladder (n = 6). 22 patients had diabetes mellitus. A total of 103 pathogens was isolated from the urine of 85 patients, the most frequent being E. coli, Proteus spp. and Enterococcus faecalis. 98% of patients with UTI and 85% of patients with endometritis were clinically cured. Adverse drug events were observed in 6 patients.

Pyelonephritis emphysematous (PE) is a life threatening renal infection which is observed practically exclusively as a serious complication of diabetes mellitus. 95% of the 73 cases which have been reviewed were found in diabetic patients. The symptomatology resembles that of severe acute pyelonephritis but the disease differs from this in that, in PE, emphysema develops in the actual renal parenchyma and/or in the perirenal tissues. The most important single factor in the etiology appears to be ischaemia of the tissues which are employed as growth media for the microorganisms involved. Infections with E. coli, Klebsiella pneumoniae, Aerobacter and Proteus are the most commonly found. Isolated cases with Candida and Cryptococcus neoformans have been observed. The mortality in untreated cases of PE is 100%. With medical treatment alone, the mortality decreases to 73% while, when combined medical and surgical intervention is employed, the mortality can be reduced to 30%.

Ten cases of penoscrotal gangrene seen in our department over the last 8 years are presented. In 80% of patients causative factors of the gangrenous process were demonstrated and were equally distributed between urology and colorectal pathologies. The most commonly associated pathology was diabetes mellitus affecting up to 50% of our patients. Two or more germs were isolated from the necrotic-purulent material for cultures, mainly E. coli (90%) and Proteus mirabilis (50%) as aerobic organisms, and Bacteroides fragilis (40%) in the anaerobic group. Despite emergency surgical therapy and high doses of broad spectrum antibiotics, mortality in our series was about 20%.

Bactericidal activity in compromised host's serum i.e. patients with cancer, the elderly, diabetes, was stronger than that in normal serum against Proteus mirabilis (P. mirabilis) but was weaker against Klebsiella pneumoniae (K. pneumoniae). Against Escherichia coli (E. coli), bactericidal activity on serum of patients with cancer was weaker in the following order, that in elderly serum, that in diabetic serum. Against Proteus vulgaris (P. vulgaris), bactericidal activity in elderly serum was similar to that in normal serum but was stronger than that in serum of patients with cancer. Against Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus), bactericidal activity in elderly serum and diabetic serum was similar to that in normal serum but was weaker than that in serum of patients with cancer. Piperacillin showed bactericidal activity in nutrient broth, normal serum and compromised host's serum at a concentration of 1/4 MIC against E. coli, P. mirabilis and P. aeruginosa. Aspoxicillin showed bactericidal activity in nutrient broth, and bactericidal or bacteriostatic activity in normal serum and serum of patients with cancer against E. coli and P. aeruginosa. While cefazolin and cefmetazole slightly inhibited the growth of bacteria in nutrient broth, they showed hardly any bactericidal activity in normal serum and compromised host's serum.

A survey was carried out of all urinary tract infections which developed bacteremia during an 18 month period. The number of episodes of bacteremia of urinary origin (BUO) detected in our institution during that period was 108. The urinary tract was the most common origin of the cases of community acquired (CA) bacteremia and the third in the hospital acquired (HA) cases. In both types, the most frequent organism was E. coli (69.6% and 40%, respectively). The most common underlying diseases were diabetes mellitus (25.7%) and neoplasia (20%); nephrourologic disorders of some type were present in 29.6% of cases. In 81% of HA episodes there were urinary catheters as risk factors. In the CA bacteremias, the gram-negative bacilli except Pseudomonas aeruginosa had a 100% sensitivity to aminoglycosides. Sensitivity to first generation cephalosporins was detected in 81% of the E. coli and in 100% of the Klebsiella spp strains. In HA cases, amikacin (100% of E. coli, Pseudomonas, Klebsiella and Proteus) and cefotaxime (except Pseudomonas) were the antibiotics to which the highest rates of sensitivity were found. Overall mortality rate of BUO was 16.6% (13.6% for CA and 21.5% for HA); in 6% and 5% of cases, respectively, death was directly associated with bacteremia.

We have evaluated 283 consecutive hospital acquired urinary tract infections (HAUTI) in a University hospital (incidence 5.6% of admissions). In females, spontaneous, symptomatic and younger patient infections predominated, while in males HAUTI were mostly asymptomatic, after catheterization and in elderly patients. Chronic nonfatal diseases--particularly neurologic disease and diabetes--, old age, previous antibiotic use, the postoperative period, and cancer were the major general predisposing factors, mostly because they involved urological procedures. There was an urethral catheter in 78% of cases, with questionable indication or maintenance in 37%. In 65% of cases there were clinical data attributable to HAUTI; however, on strict criteria only 5% of pyelonephritis and 24% of cystitis were detected. Mortality rate was 0.4%. Etiology was E. coli in 29%, Proteus in 13%, Enterobacter in 12%, enterococcus in 11.5%, Serratia in 7%, Pseudomonas in 6.5%, and Klebsiella in 6.5%. There were differences regarding endogenous and hospital flora on the basis of sex, hospital situation, catheterization, mobility, and previous duration of hospitalization. The microbial resistance pattern was high in the hospital flora. The major therapeutical problem was the high number of unnecessary treatments representing the automatic medical response to the finding of a positive urine culture.
