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.

126 cases of sepsis were retrospectively studied in an Internal Medicine Department, giving special attention to the clinical evolution. 67 males and 59 females with a median age of 65 years old were discovered. 92% had one or more diseases, mainly COLD (30%) and diabetes mellitus (28%). The septic sources were urinary (37%) and respiratory (31%). 84% of the germs were gram (-), mainly E. Coli and Proteus sp. A mortality rate of 36% was found, the primary rates being: eighth decade (52%), patients with neoplastic disease (46%), biliary tract diseases (64%), endocarditis (66%), infection by Serratia (60%), Pseudomonas (50%), shock (55%) and DIC (50%). These last two complications were analysed and found to be the more frequent (35% and 6.3% respectively), also being those with higher mortality rate. Finally, the prognostic factors are established based on the results obtained.

Malignant external otitis is an invasive pseudomonal infection characteristically afflicting the elderly patient with diabetes mellitus. Therapy has traditionally consisted of the long-term administration of combination parenteral antibiotics, but morbidity and mortality remain substantial despite this therapy. We treated 11 consecutive patients with the oral combination of ciprofloxacin (750 mg twice daily) and rifampin (600 mg twice daily) for 6 to 12 weeks (mean, 8 weeks). Pseudomonas aeruginosa was isolated from ear canal or mastoid, and bone destruction was documented by computed tomography in all patients. Seven patients (64%) had ear irrigation before onset of the infection. Ten patients fulfilled the criteria of both clinical and bacteriologic cure. No serious adverse reaction to either antibiotic was observed. Otalgia and otorrhea responded at a mean of 6 and 4 days, respectively, following the initiation of therapy. The erythrocyte sedimentation rate fell from a mean pretherapy value of 81 mm/h (range, 41 to 138 mm/h) to 18 mm/h (range, 3 to 45 mm/h) after the completion of antibiotic therapy. Minimum inhibitory and bactericidal concentrations established that all organisms were sensitive to ciprofloxacin. Time-kill curve and checkerboard assays failed to demonstrate either synergy or antagonism between ciprofloxacin and rifampin. Serum inhibitory and bactericidal titers showed minimal increase in inhibition and killing of the bacteria with the addition of rifampin. Rifampin did not alter the pharmacokinetics of ciprofloxacin. The successful use of oral antibiotics for this difficult infection may be a major advance. Reduction in antibiotic costs and hospitalization and convenience of oral administration were of notable benefit.

Melioidosis is an infection of humans and animals caused by a gram-negative motile bacillus, Pseudomonas pseudomallei. Forty-nine patients with melioidosis complicating diabetes mellitus, collagen vascular disorders, leukemia/lymphoma, and other hematologic malignancies are described. Twenty-nine of these patients had disseminated/septicemic infection, two developed toxic shock syndrome, and one with AIDS experienced recrudescent melioidosis. Patients with disseminated melioidosis often have a variety of defects in cellular immunity both in vitro and in vivo. In humans with recrudescent melioidosis, cellular immunity can be transferred by a transfer factor and by levamisole, a cellular immunopotentiating agent. The results of the treatment of our patients with disseminated/septicemic melioidosis with antimicrobial agents in combination have been successful. In recent years, four cases of fungal arteritis due to Pythium species and one case of keratitis due to Pythium were seen. Almost all patients with fungal arteritis had thalassemia; all presented with pain in the lower extremities and gangrenous lesions of the toes. Pythium species, an aquatic Phycomycetes, was identified in these cases as a human pathogen on the basis of clinical features, pathologic findings, and--of greatest importance--the isolation of the etiologic fungi. These five cases with remarkably similar presentations exhibited certain similarities with and differences from cases of mucormycosis, entomophthoromycosis, and peniciliosis.

A case of Pseudomonas pseudomallei pneumonia with septicemia is described. The onset was insidious with paucity of systemic symptoms except fever. Diabetes mellitus and alcoholism were associated problems. Initially blood cultures were negative but subsequently P. pseudomallei was isolated. The outcome was fatal. Unless diagnosed early and treated appropriately, patients often succumb to septicemic shock.

Twenty-six episodes of Pseudomonas aeruginosa bacteremia treated with intravenous ceftazidime, 4-6 g/day were evaluated. Treatment was begun within the first 24 hours after the isolation of the microorganism and was maintained for 10-12 days. In two patients with neutropenia amikacin was added during the initial 48-72 hours until the susceptibility to ceftazidime was known. All isolates were sensitive to ceftazidime. The most common underlying diseases were neoplasia (12), diabetes with stroke (4), neurosurgical and vascular procedures (4), rheumatoid arthritis (2), burns (2), cor pulmonale (1), and hypertension (1). The origins of bacteremia were urinary (12), pulmonary (9), and unknown (5). The infection was hospital-acquired in 77% and community-acquired in 23%. A critical clinical status and the presence of complications were significantly (p less than 0.01) associated with an increased mortality rate. Clinical outcome was good in 18/26 (70%), with a 30% mortality rate. The microbiological evolution showed 14 eradications, 6 persistences, 3 relapses and 3 colonizations. Resistance did not develop during therapy. Ceftazidime may be a good alternative therapy for these severe infections, although wider comparative studies are required for a better evaluation.

In a prospective study of all patients with Pseudomonas pseudomallei infections admitted to a large provincial hospital in northeastern Thailand, 63 cases of septicemic melioidosis and 206 patients with other community-acquired septicemias were documented during a 1-y period. Apart from P. pseudomallei, the spectrum of bacteria isolated from blood cultures and the overall mortality (32%) were similar to those previously reported elsewhere. Death from septicemia was associated with failure to develop a leukocytosis or pyrexia over 38 degrees C, azotemia, hypoglycemia, and jaundice. Septicemic melioidosis presented mainly in the rainy season, occurred predominantly in rice farmers or their families, and was significantly associated with preexisting diabetes mellitus or renal failure (P = .03). Blood-borne pneumonia and visceral abscesses were common and the mortality was high (68%; P less than .001). The response to appropriate treatment was slow (median fever clearance time 5.5 d) and the median duration of hospital stay was 4 w. Septicemic melioidosis is a major cause of morbidity and mortality in northeast Thailand.

The author evaluated 142 patients aged 65 years or older with microbial keratitis. There were relatively high rates of Pseudomonas aeruginosa infection unassociated with contact lens wear and of Streptococcus pneumoniae infection. The rates of quasicommensal and enteric infections were not proportionately elevated. Corneal disease, use of topical corticosteroids and use of contact lenses were the main predisposing factors. Patients with diabetes mellitus, dementia or chronic alcoholism appeared to be at higher risk. Trauma was rarely a factor. Complications requiring surgery were common. Corneal perforation developed in 20% of the patients, and endophthalmitis developed in 6%. The elderly often do not tolerate intensive topical antibiotic treatment well. Supplementary subconjunctival antibiotic injections under local anesthesia may be necessary. Corneal tissue glue, tarsorrhaphy and conjunctival flaps are probably underused in this age group.

Malignant external otitis is an infection of the external ear canal, mastoid, and base of the skull caused by Pseudomonas aeruginosa. The condition occurs primarily in elderly patients with diabetes mellitus. Current theories on pathogenesis and anatomic correlations are reviewed. Severe, unrelenting otalgia and persistent otorrhea are the symptomatic hallmarks of the disease, whereas an elevated erythrocyte sedimentation rate is the only distinctive laboratory abnormality. Iatrogenic causes such as administration of broad-spectrum antibiotics and aural irrigation may play a predisposing role in high-risk populations. The disease can result in cranial polyneuropathies (with facial nerve [VII] paralysis being the most common) and death. The mainstay of treatment is administration of antipseudomonal antibiotics for four to eight weeks. Recurrence is common, and mortality remains at about 20 percent despite antibiotic therapy. Given the increasing longevity of diabetic patients, the frequency of this disease is increasing. Internists, family practitioners, and ambulatory care physicians must now be cognizant of the presenting symptoms, while infectious disease specialists and otolaryngologists need to be appraised of strides in diagnosis and therapy. The role of surgery should be minimized. Use of new diagnostic radiologic modalities and new antipseudomonal antibiotics discussed in this review should lead to improved outcome.
