CASE HISTORY AND OFFICE DIAGNOSIS A 7-month-old uncircumcised male infant had vomiting, diarrhea, and low grade fever (38.4°C) 2 days before coming to the pediatrician's office. One day before seeing the baby, the physician prescribed Pedialyte and acetaminophen elixir. The child appeared active to the pediatrician. Mucous membranes were slightly dry and tears were present. His blood pressure was 98/62 mm Hg, pulse rate 92 beats per minute, and temperature 38°C. Laboratory evaluation included an analysis and culture of catheterized urine sample: specific gravity, 1.025; pH, 6.0; protein, trace; blood, negative; sugar and ketones, negative; sediment—0 to 1 red blood cells per high-power field; 6 to 8 white blood cells per high-power-field and no bacteria. Based on the differential diagnosis of viral gastroenteritis vs urinary tract infection, the patient was sent home with a prescription for Pedialyte and acetaminophen and the parents were told to call the office in 24 hours for test results. The urine culture was positive for greater than 100 000 colonies per milliliter of a single organism which was later identified as Escherichia coli and sensitive to all antibiotics. The child was started on a regimen of amoxicillin. Two weeks later, a repeat urine culture was negative for bacteria.

Tract Infections

In this prospective study of 442 infants younger than 8 weeks of age who attended a pediatric emergency department with temperature ≥100.6°F (38.1° C), urinary tract infections (UTIs) were found in 33 patients (7.5%), 2 of whom were bacteremic. Clinical and laboratory data were not helpful for identifying UTIs. Of the 33 patients with UTIs, 32 had urinalyses recorded; 16 were suggestive of a UTI (more than five white blood cells per high-power field or any bacteria present). Of the 16 infants with apparently normal urinalysis results, three had an emergency department diagnosis suggesting an alternative bacterial focus of infection. If the physician had decided on the basis of apparently normal urinalysis results to forgo obtaining a urine culture, more than half of the UTIs would have been missed. Bag-collected specimens were significantly more likely to yield indeterminate urine culture results than either catheter or suprapublic specimens. In addition, uncircumcised males were significantly more likely to have a UTI than circumcised boys. These results suggest that a suprapubic or catheter-obtained urine specimen for culture is a necessary part of the evaluation of all febrile infants younger than 8 weeks of age, regardless of the urinalysis findings or another focus of presumed bacterial infection.

Objective.To identify patients presenting with isolated hematuria and/or pyuria in the absence of other systemic lupus erythematosus (SLE) disease activity, describe their demographics, and determine whether they present with evidence of SLE flare in a period adjacent to the presentation.Methods.We studied patients followed at the University of Toronto Lupus Clinic between 1970 and 2012. An episode of isolated hematuria (> 5 red blood cells per high power field) and/or pyuria (> 5 white blood cells per high power field) was defined as 2 consecutive visits with these findings in the absence of other concurrent SLE manifestations such as proteinuria, casts, or azotemia. We then excluded patients whose findings might be explained by urinary tract infections, menstruation, urolithiasis, and/or anticoagulation. Only patients presenting with no other SLE disease activity were included.Results.Isolated hematuria and/or pyuria were identified in 49 patients, of whom 17 were excluded according to the criteria above, leaving 32. Twenty-four patients had another renal manifestation 1 year before and/or after the occurrence; 27 had a non-renal manifestation 1 year before and/or after the occurrence; 3 patients had a biopsy in the same time frame, all with evidence of active lupus nephritis. Therefore the majority of patients with an occurrence of isolated hematuria and/or pyuria had evidence of renal or other non-renal SLE disease activity at a time adjacent to this presentation.Conclusion.Although not proven, our results suggest that these manifestations were associated with SLE activity, either before or after the episode, and therefore may represent a phase of active disease.

Abstract Background One of the most readily available and cost effective tests in the diagnosis of urinary tract infections (UTI) is the urinalysis. Problems arise when antibiotic treatment is initiated in a patient who does not display typical signs and symptoms of UTI and for whom a urinalysis was obtained for other reasons. Methods This was a retrospective observational study carried out on 1000 patients with positive urine nitrite. Medical records were identified with subsequent analysis of urine culture and symptomatology. Recorded and analyzed data included: age, sex, location (emergency room (ER) or hospital ward), findings on urinalysis (pH, presence of leukocyte esterase(LE), epithelial cells, bacteria, and white blood cells (WBCs)) and antibiotic treatment. Results Of these 1000 patients with positive nitrite, we excluded 815 patients (81 had missing data, 466 met exclusion criteria and 268 had symptomatic UTI). 185 were found to not have any symptoms of a UTI. Inappropriate antibiotic treatment occurred in 108/185 patients (58.4%) and was significantly associated with greater amounts of bacteria and WBCs in the urinalyses (P = 0.008 and P = 0.029, respectively). It was also significantly more likely to occur in the ER than the hospital wards (92/147 treated in the ER vs. 16/37 treated on the hospital wards, P = 0.033). There was no significant association between antibiotic treatment and age, sex, urine pH, urine LE, and urine epithelial cell amounts (P > 0.05). Urine cultures were not obtained in 69.7% of patients. A positive urine culture was significantly associated with inappropriate antibiotic treatment (P = 0.0006). The two most common presenting complaints were psychiatric complaints (21.6%) and vaginal bleeding (14.6%). Conclusion Urinalysis can be an invaluable diagnostic tool, but must be used and interpreted appropriately. There is a misperception that pyuria with bacteriuria defines UTI. However, positive results on a urinalysis alone in an asymptomatic patient is not enough to diagnose a UTI, and antibiotic treatment is only indicated in specific circumstances as outlined by IDSA guidelines for the treatment of asymptomatic bacteriuria. Further education targeting appropriate interpretation of urinalyses and IDSA guidelines is needed to decrease the unnecessary use of antibiotics. Disclosures All authors: No reported disclosures.

Neutrophil Gelatinase

Background and Aims: This study aimed to investigate the amount of Neutrophil gelatinase-associated lipocalin (NGAL) in patients' urine with Grampositive cocci infections  Materials and Methods: The microbial culture was prepared from 100 urine samples and the results were recorded. The genus and bacterial were species identified and an antibiogram test was conducted to investigate their resistance. Human Lipocalin /NGAL enzyme-linked immunosorbent assay test was used. To analyze the data, Tukey and One Way ANOVA tests were used. Results: The highest mean of NGAL in the patient group was related to the men's category with 8.77, and the gender had a significant impact on the mean of NGAL. White blood cells has a significant impact on the mean of NGAL (p<0.05). The negative significance of the mean value also indicates the amount of NGAL being higher in the patient group.  Conclusions: These data suggest a relationship between the amount of NGAL with white blood cells value in patients who present urinary infection of Grampositive cocci. NGAL value plays an important role as an adjuvant and surrogate marker in early diagnosis of urinary tract infections and acute renal damage in line with microbiological investigations.

Among 101 nursing home residents with suspected urinary tract infection (UTI), we determined the negative predictive value of dipstick testing for leukocyte esterase and nitrite to be 100% (95% confidence interval, 74%-100%), compared with laboratory evidence of UTI (greater than 10 white blood cells/mm3 on urinalysis and greater than 100,000 colony forming units/mL on urine culture). Nursing home dipstick testing effectively excluded the possibility of UTI.

Dogs with diabetes mellitus may develop occult urinary tract infections. In this study, diabetic dogs with negative and positive bacterial urine cultures were compared. Records from 51 dogs with diabetes mellitus were reviewed at the University of Illinois. No difference was identified between the groups in urine specific gravity, pH, glucose, ketones, protein, red blood cells, white blood cells, or epithelial cells. Dogs with occult urinary tract infection did have an increased incidence of bacteriuria, but this was not a consistent finding. Therefore, the urine on all diabetic dogs should be cultured to accurately identify the presence or absence of bacterial urinary tract infections.

Material and methods. The study included patients (n=164) in peri- and postmenopause, having a laboratory-confirmed picture of the genitourinary menopausal syndrome - atrophic vulvovaginitis and suffering from recurrent lower urinary tract infections (UTI) - cystitis and urethritis. All patients underwent standard antibacterial therapy (ABT) UTI in accordance with the results of bacteriological urine culture according to Russian clinical guidelines on urology. Against the background of ABT, 164 patients received additional therapy with Trioginal® (the study group - SG) containing estriol, micronized progesterone and Lactobacillus casei rhamnosus Doderleini 35 (LCR 35) lactobacillus strain. Trioginal® was administered intravaginally in two stages: for 20 days, 2 capsules per day, then for 10 days, 1 capsule per day. In the comparison group - CG (n=67) with ABT, Ovipol Klio® (estriol monopreparation) was additionally intravaginally used in two stages: for 14 days, 1 suppository per day, then for 2 weeks, 1 suppository 2 times a week. The control group consisted of 30 patients receiving only standard ABT UTI, local hormone therapy for vulvovaginal atrophy (VVA) was not performed. The observation period was 12 months after the end of the course of therapy. At all stages of treatment, a subjective and objective assessment of the severity of urination disorders and urogenital atrophy (UDI-6 questionnaire), their impact on the quality of life of patients (questionnaire IIQ-7), indicators of bacteriuria, bacterial urine culture and vaginal biocenosis, frequency of undesirable phenomena were carried out. According to the initial characteristics of the group of patients were comparable. Results. At all stages of the study, in the group of patients who received therapy with the use of the Trioginal® drug, there was a significant improvement in the clinical picture of urination disorders compared to the CG and the control (main) group - MG (in SG - 18% at the end of therapy versus 100% before the start of therapy; CG - 26 % versus 100% respectively; Ledger - 58% versus 100% respectively; p

Objectives: To investigate clinical characteristics, bacterial characteristics, drug resistance status in patients with urinary tract infections treated at Department of Urology, Hue University Hospital. Materials and Method: The study was conducted in 474 patients with urological disease treated at Department of Urology, Hue Universiry Hospital from July 2017 to April 2018. Urine culture was done in the patients with urine > 25 Leu/ul who have symptoms of urinary tract disease or infection symptoms. Patients with positive urine cultures were analyzed for clinical and bacterial characteristics. Results: 187/474 (39.5%) patients had symptoms associated with urinary tract infections. 85/474 (17.9%) patients were diagnosed with urinary tract infection. The positive urine culture rate was 45.5%. Symptoms of UTI were varied, and no prominent symptoms. E. coli accounts for the highest proportion (46.67%), followed by, Staphycoccus aureus (10.67%), Pseudomonas aeruginsa (8,0%), Streptococcus faecali and Proteus (2.67%). ESBL - producing E. coli was 69.23%, ESBL producing Enterobacter spp was 33.33%. Gram-negative bacteria are susceptible to meropenem, imipenem, amikacin while gram positive are vancomycin-sensitive. Conclusions: Clinical manifestations of urinary tract infections varied and its typical symptoms are unclear. E.coli is a common bacterium (46.67%). Isolated bacteria have a high rate of resistance to some common antibiotics especially the third generation cephalosporins and quinolones. Most bacteria are resistant to multiple antibiotics at the same time. Gram (+) bacteria are susceptible to vancomycin, and gram (-) bacteria are susceptible to cefoxitin, amikacin, and carbapenem.

ABSTRACT The prevalence of urinary tract infections (UTIs) in dogs with Type I intervertebral disc extrusion has been reported as high as 38% within 6 wk of surgery. Proper treatment of a UTI is important with myelopathy because it is a risk factor for persistent infection and reinfection in dogs. The study authors' investigated the incidence of UTIs in dogs having received either cefovecin or cefazolin as a preoperative prophylactic antibiotic for thoracolumbar hemilaminectomy. Thirty-nine dogs were retrospectively identified and assigned to groups based on preoperative antibiotic administration and postoperative urinary tract management. Urinalysis and urine culture performed preoperatively, at 2 wk, and at 6 wk, were reviewed to determine the incidence of UTIs. Urinary tract management, grade of neurologic deficit, time to ambulation, and time to voluntary urination were identified to evaluate for additional risk factors. No significant prevalence of UTI incidence was appreciated between the cefovecin and cefazolin groups. Patients with higher grades of neurologic deficit and that took longer to regain ambulation and voluntary urination were at significantly greater risk for UTIs throughout the postoperative period. This study reemphasizes the importance of continued surveillance for UTIs in patients with prolonged neurologic recovery.
