We investigated 117 patients undergoing percutaneous nephrolithotomy, percutaneous nephrostomy, ureterorenoscopy, the push-back or push-bang procedure for ureteral stones, Double-J* ureteral stenting plus extracorporeal shock wave lithotripsy (ESWL), ESWL alone or cystoscopy. Blood samples obtained before, during and 1 hour after the procedure were cultured and assayed for endotoxin and tumor necrosis factor. Also, culture was done of the urine preoperatively and postoperatively, and the stones when they could be retrieved. There was a temporal relationship among bacteremia, endotoxemia and elevation of tumor necrosis factor. An unexpected finding was peroperative endotoxemia in a significant number of patients with stones. Risk factors noted for postoperative bacteremia, endotoxemia and/or elevation of tumor necrosis factor included preoperative endotoxin level, type of procedure, presence of preoperative bacteriuria and pyuria. With respect to the procedure the risk was greatest after the push-back method and least after cystoscopy (push-back method greater than percutaneous nephrolithotomy/percutaneous nephrostomy greater than Double-J stenting plus ESWL greater than ureterorenoscopy greater than ESWL greater than cystoscopy). If the risk factors are measured preoperatively it may be possible to identify the risk of postoperative bacteremia/endotoxemia and, therefore, septic shock postoperatively. Our patients appear to be a good clinical model to investigate the problems related to septicemia.

Autosomal dominant polycystic kidney disease (ADPKD) is the commonest hereditary nephropathy. We collected 92 cases in VGH. Diagnosis was confirmed by intravenous pyelogram, renal sonogram, or renal CAT scan. The incidence of having positive family history was just only 28.3%. Patients were diagnosed at the mean age of 54 +/- 11 years (26-74 years). The common clinical findings were hypertension (73.9%), abdominal mass, proteinuria, anemia, azotemia, abdominal or back pain and pyuria in orders. Hypertension might present in the early stage with normal renal function (near 40%). Polycystic liver was the major extrarenal lesion (57.6%), but the incidence of abnormal liver function was only 10.1%. Enlarged kidneys were not always palpable, even at end stage of renal function (mean age 56 +/- 9 years, 89.4% kidney palpable). Patient's urine amount was usually nonoliguric, even in uremic stage (82.9%). Sepsis was the first cause of death. Cardiovascular disease and uremia were followed in sequence. Their expired mean age was 61 +/- 7 years (53-74 years).

During the period from July to November 1984, 265 consecutive febrile infants younger than one year of age were evaluated in a pediatric emergency department. None had a source of infection on physical examination, and all were admitted with the diagnosis of "rule out sepsis." During the month of July, all patients with positive urine culture results had their urine sample collected by bag. In no instance was there a clinical diagnosis of urinary tract infection because of the presence of contaminant bacteria. A program was instituted on August 1, 1984 which encouraged the utilization of either bladder catheterization or suprapubic aspiration techniques, and discouraged bag collection technique for culturing urine. Over the next four months, catheterization and suprapubic aspiration techniques increased from 0 to 72%; bag technique decreased from 100 to 27%. Also, during this period the incidence of urinary tract infection increased to 5.53%. Seventy-five percent of patients with urinary tract infection had an initial urinalysis with less than 5 to 10 white blood cells/HPF, and 60% had an initial urine specific gravity of less than or equal to 1.005. Eighty-seven percent of infants with a positive urine culture result collected by bag technique revealed a mixture of more than three organisms. The technique utilized for collecting urine for culture in infants has a major impact on the incidence of urinary tract infection. The absence of pyuria is not a reliable indicator of the absence of urinary tract infection. Infants with urinary tract infection may have a transient loss in urine concentrating ability early in the course of their infection.

We studied 182 sick, febrile (temperature greater than 38 degrees C) infants less than 3 months of age, who presented at our Tripler Army Medical Center, Honolulu, during a one-year period, to determine the relative causes of fever in this age group. Blood, cerebrospinal fluid, urine, nasopharyngeal secretions, and stool specimens were cultured for bacterial and viral pathogens. Paired acute and convalescent sera were collected to serologically confirm infection in infants from whom viral isolations were obtained only from the nasopharynx or stool. A viral pathogen was isolated in 75 infants (41%) and a bacterial pathogen was isolated in 27 infants (15%). Nonpolio enteroviruses were the most common pathogens demonstrated. They were isolated from 64 infants (35%), and 40 (62%) of these infants had aseptic meningitis, the most frequently made diagnosis. Urinary tract infection was the most common bacterial infection observed. It occurred in 20 infants (11%) and was most often seen without associated pyuria in uncircumcised male infants. Salmonellosis, the second most common bacterial infection, was observed in six infants (3%), and two of these did not have diarrhea or other gastrointestinal tract symptoms. No infant had septicemia and only one infant had bacterial (group B streptococcal) meningitis.

Clinical studies of aztreonam (AZT) were performed in 10 pediatric cases. One transient pyuria case with 10(3)/ml E. faecalis detected in urine was excluded from clinical evaluation, because the presence of infection was unclear. Results were as follows: AZT was effective on 1 patient with meningitis (causative organism: H. influenzae), who was treated with 41.7 mg/kg 4 times a day. Results of administration of 58.1-78.9 mg/kg 3 or 4 times a day by intravenous injection for 1 E. coli sepsis-and-pyelonephritis complication case and 7 pyelonephritis cases (causative organisms: E. coli in 1, E. coli + E. faecalis in 1, E. faecalis in 1, P. aeruginosa in 3 and unknown in 1) were excellent in 4, good in 2 and poor in 2 cases. The pathogens of the 2 poor cases were E. faecalis and P. aeruginosa, respectively. Six of the pyelonephritis cases had vesicoureteral refluxes as an underlying condition. Clinical and microbiological effects of AZT were considered to be closely correlated with its MIC values. No side effect was recognized. Though abnormal laboratory findings were obtained in 4 cases, including elevations of GOT X GPT in 2 cases, GPT elevation in 1 case and plateletcount increase in 1 case. All of these abnormalities were minor and transient. The serum concentrations of AZT for a two-month-old patient with pyelonephritis were 65, 50, 35, 22.8 and 12.4 micrograms/ml at 1/2, 1, 2, 4 and 6 hours, respectively and T1/2 was 2.42 hours after injecting AZT 20 mg/kg by intravenous injection.(ABSTRACT TRUNCATED AT 250 WORDS)

Urinary tract infection (UTI), a relatively common cause of fever in infancy, usually consists of pyelonephritis and may cause permanent renal damage. This study assessed (1) the prevalence of UTI in febrile infants (temperature > or = 38.3 degrees C) with differing demographic and clinical characteristics and (2) the usefulness of urinalysis in diagnosing UTI. We diagnosed UTI in 50 (5.3%) of 945 febrile infants if we found > or = 10,000 colony-forming units of a single pathogen per milliliter in a urine specimen obtained by catheterization. Prevalences were similar in (1) infants aged < or = 2 months undergoing examination for sepsis (4.6%), (2) infants aged > 2 months in whom UTI was suspected, usually because no source of fever was apparent (5.9%), and (3) infants with no suspected UTI, most of whom had other illnesses (5.1%). Female and white infants had significantly more UTIs, respectively, than male and black infants. In all, 17% of white female infants with temperature > or = 39 degrees C had UTI, significantly more (p < 0.05) than any other grouping of infants by sex, race, and temperature. Febrile infants with no apparent source of fever were twice as likely to have UTI (7.5%) as those with a possible source of fever such as otitis media (3.5%) (p = 0.02). Only 1 (1.6%) of 62 subjects with an unequivocal source of fever, such as meningitis, had UTI. As indicators of UTI, pyuria and bacteriuria had sensitivities of 54% and 86% and specificities of 96% and 63%, respectively. In infants with fever, clinicians should consider UTI a potential source and consider a urine culture as part of the diagnostic evaluation.

Urinary tract infections (UTIs) are still one of the most common bacterial infections in pregnant and non-pregnant women. It is estimated that about 10-20% of all women suffer from a UTI at some point in life. The presence of UTI is defined as the existence of urinary symptoms such as frequency of urination and dysuria with or without bacteriuria or pyuria. The prevalence of bacteriuria in females varies from less than 1% in infants to 10% and more in older women. There are major differences in the clinical features between young and elderly women depending on the different pathogenesis, microbiology and general condition. Especially for elderly women, symptomatic and asymptomatic bacteriuria presents a risk factor for bacteraemia, sepsis and also increased mortality. During pregnancy, the prevalence of bacteriuria does not change but there are some changes in the pathogenesis that increase the rate of pyelonephritis. Asymptomatic bacteriuria rarely resolves spontaneously during this time. For non-pregnant women, short therapy strategies are recommended, preferably 3 days of trimethoprim-sulphamethoxazole (TMP/SMX) or quinolones. In pregnant women, therapy with amoxycillin or an oral cephalosporin is considered optimal.

A case of psoas abscess associated with diabetes mellitus in the elderly is reported. A 81-year-old male who had been followed for cerebral thrombosis, diabetes mellitus and basal cell carcinoma was admitted to our hospital because of high fever. Leukocytosis, a positive CRP test and pyuria were seen. Proteus mirabilis and Escherichia coli were detected by urine and blood culture, respectively. He was treated with antibiotic therapy for urinary tract infection and sepsis. After starting treatment, a low grade fever continued. On the twenty first hospital day he developed pyrexia again, and a large abscess was demonstrated in the right psoas muscle by pelvic couputed tomography. The abscess was drained and a specimen from it yielded E. coli on culture. Treatment with antibiotics and drainage resulted in symptomatic improvement. In Japan, 82 cases of psoas abscess have been reported from 1990 to 1994. Four cases of these reports were above eighty years old. The experience with this case indicates the necessity of adequate care in cases of elderly diabetes complicated by psoas abscess.

A 3-week-old male infant, born full term without complication, developed septic arthritis of his left shoulder. His joint fluid, blood, and bone marrow were all positive for Escherichia coli. Urinalysis demonstrated pyuria. Urine culture obtained after one dose of ceftriaxone and several doses of nafcillin was negative. Work-up revealed a refluxing, right single ectopic ureter with severe hydroureteronephrosis and a non-functioning ipsilateral kidney. After appropriate management of the musculoskeletal infection, he underwent a right nephroureterectomy. Coliform septic arthritis is exceedingly rare in children, with only a few cases reported. We report the first case of septic arthritis with anomalous genitourinary tract development as the source of bacterial seeding. This report re-emphasizes the need to screen the urinary tract in all cases of pediatric gram-negative sepsis.

Deep sepsis in the involved joint after hip or knee arthroplasty may be the result of hematogenous seeding from a remote infectious source. This mechanism has been used to explain the well-documented association between postoperative urinary tract infections and subsequent joint infection after hip or knee arthroplasty. However, it is unclear whether there is an association between preoperative bacteriuria and deep prosthetic infection. The purpose of this review is to identify perioperative risk factors associated with bacteriuria that have a positive correlation with deep joint sepsis following total hip or knee arthroplasty. The classic symptoms of dysuria, urgency, and frequency seen with urinary tract infections are often absent in the elderly despite the presence of urine coliforms; in these patients, pyuria (as indicated by the presence of more than 1x10(3) white blood cells per milliliter of noncentrifuged urine) may be used as a preliminary screening criterion. If there are irritative symptoms, the presence of more than 1x10(3) bacteria per milliliter of urine should be regarded as indicative of a urinary tract infection. If there is bacteriuria without symptoms of urinary irritation or obstruction, the current literature supports proceeding with total joint arthroplasty and treating those patients with urine colony counts greater than 1x10(3)/mL with an 8- to 10-day postoperative course of an appropriate oral antibiotic. Postponement of total joint surgery should be considered if preoperative evaluation reveals symptoms related to obstruction of the urinary pathway. Irritative symptoms in combination with a bacterial count greater than 1x10(3)/mL should also serve as an indication to postpone surgery. To diminish postoperative urinary tract infection, a bladder catheter should be inserted immediately preoperatively and removed within 24 hours of surgery to diminish the risk of urinary retention, which has been shown to increase the likelihood of a postoperative urinary tract infection.
