species, typically considered commensal organisms of the human urogenital tract, have been implicated in various urinary tract infections (UTIs), including the rare and challenging presentation of pyelonephritis. This case report describes a unique instance of pyelonephritis induced by , characterized by a negative routine urine culture and a lack of response to empirical antibiotic treatment, highlighting the complexities associated with diagnosing and managing infections caused by atypical pathogens. A 50-year-old female presented to the emergency department with symptoms suggestive of UTI, including fever, vomiting, and dysuria. However, initial urine analysis was notable for pyuria while routine bacterial culture returned negative results, creating a diagnostic dilemma. Empirical treatment with third-generation cephalosporin was initiated. However, the patient's condition failed to improve, raising concerns about antibiotic resistance or atypical pathogens. Subsequent molecular diagnostics, precisely polymerase chain reaction (PCR), identified as the causative agent. This prompted a change in the treatment regimen to doxycycline, to which the patient showed significant clinical improvement. Physicians should be aware of as a potential cause of pyelonephritis, especially in cases of culture-negative UTIs and when patients do not respond to standard empirical treatment. This case emphasizes the importance of considering atypical pathogens in differential diagnosis and the role of molecular diagnostic techniques in guiding appropriate management.

Catheter-associated urinary tract infections (CAUTIs) are a frequent hospital-acquired infection and public health concern. In an attempt to reduce the number of CAUTIs, an intervention that emphasized the appropriate laboratory evaluation by ordering providers was implemented. This intervention supplemented ongoing standard bundle protocols. Compared to the 16 months before the intervention, there was a significant decrease in the number of CAUTIs during the 12-month intervention period.

A 59-year-old woman who has HER2-negative advanced gastric cancer with peritoneal dissemination was treated with nivolumab plus SOX therapy as primary treatment, and hemorrhagic cystitis occurred on the 28th day after the 6 courses. On the 21st day after the 7 courses, right knee arthralgia appeared, and on the 26th day, she was admitted to the hospital due to a fever of 39℃ and anorexia. After admission, frequent diarrhea occurred and new symptoms of neck pain and left knee arthralgia appeared. Abdominal CT showed increased fatty tissue density around the sigmoid colon, and wall thickening and contrast enhancement of the mucosal surface of the bladder. Lower gastrointestinal endoscopy revealed the diffuse redness and erosions in some areas, and lymphocytic infiltration in the epithelium of the crypts was seen in biopsy from the erosions. The hemorrhagic cystitis was aseptic pyuria. Therefore, we suspected that the series of symptoms were immune-related adverse events(irAE)and started prednisolone 50 mg(1 mg/kg/day), which quickly relieved the diarrhea, cystitis and arthralgia. As a result, the patient was diagnosed as having irAE. We report a case of advanced gastric cancer who experienced multiple irAE with nivolumab plus SOX therapy, with some discussion of the literature.

Acute bacterial prostatitis (ABP) is a common disease in adults but uncommon in children. Here, we report the case of a pediatric patient without any underlying disease who was diagnosed with ABP while trying to determine the cause of fever refractory to antimicrobial therapy. A previously healthy 12-year-old boy presented with a 13-day history of fever and malaise despite initial antimicrobial treatment. Further tests revealed pyuria and enlarged prostate with possible abscesses, which led to the diagnosis of ABP based on a contrast-enhanced computed tomography (CT) scan. Although initial urine cultures were negative, was detected in subsequent cultures. Antimicrobial therapy for 10 weeks led to improvement without relapse. This case demonstrates that ABP can cause fever in children. Moreover, it shows that contrast-enhanced CT imaging can help identify the cause of fever and that administration of antimicrobials before adequate investigations can confound the diagnosis and complicate the treatment.

BACKGROUND
Urinary tract infections (UTIs) and antibiotic overexposure are common neonatal problems. Recently, evidence has emerged that a standardized approach to neonatal UTI can reduce unnecessary diagnosis without complications. This quality improvement project aimed to achieve those goals in our neonatal intensive care unit (NICU).
METHODS
A UTI diagnosis guideline was adapted from the literature with the goal of maximizing the proportion of diagnosed UTIs that conform to accepted diagnostic criteria: >10,000 CFU/mL of one organism with pyuria, or >50,000 CFU/mL of one organism regardless of pyuria. The guideline was implemented in a level III NICU. Adherence, results, and complications were monitored for 12 months.
RESULTS
Guideline adherence after implementation was favorable, as evidenced by increased adoption of urinalysis with microscopy. There was a non-significant increase in diagnostic adherence to criteria, 87% to 93%, and non-significant decrease in the rate of UTI diagnosis, 39% to 36%. Complications were not significantly changed. Most UTIs were due to gram-negative rods, especially E. coli; Enterococcus was a common contaminant.
CONCLUSIONS
A guideline for diagnosing UTIs can safely increase uniformity. In contrast to previously published results, no significant changes were seen in the rate of UTI or the proportion of diagnoses conforming to the criteria for UTI. It is likely that guideline effects depend on the established practices of NICU providers. Additionally, a consistent pattern was seen in which organisms were more likely to be judged the source of true UTIs or contaminated cultures, meriting further study.

() infection, primarily observed in elderly patients, is a rare yet emerging occurrence in the pediatric population. Advances in laboratory techniques have facilitated the increased identification of these bacteria in human infections. There have been only a few recent cases reported among children. The scarcity of literature on the clinical presentation and management of such infections in children presents a challenge for pediatricians. Here, we present the case of a 15-month-old male child with Down syndrome who presented with malodorous urine but lacked other typical symptoms of urinary tract infection. Upon investigation, urine analysis revealed pyuria, and urine culture confirmed infection. The patient also exhibited underlying bilateral mild to moderate hydronephrosis. Successful treatment was achieved with a three-day course of amoxicillin, leading to symptom resolution. This case underscores the significance of promptly identifying infection in pediatric patients presenting with malodorous urine, as a timely intervention with a short course of treatment may avert more severe and invasive infections.

In a multi-hospital cohort study of 3392 patients, positive urinalysis parameters had poor positive predictive value for diagnosing urinary tract infection (UTI). Combined urinalysis parameters (pyuria or nitrite) performed better than pyuria alone for ruling out UTI. However, performance of all urinalysis parameters was poor in older women.

Standard urine culture is the gold standard for diagnosing urinary tract infections (UTIs) but fails to differentiate true UTI from asymptomatic bacteriuria, which is important to prevent the overuse of antibiotics. Correlation with the presence or absence of pyuria can be helpful in giving a hint of the true situation. With the help of Laboratory Information System (LIS), patients' urinalysis reports can be conveniently accessed and compared simultaneously with appropriate reports. In our study, a quality improvement initiative was planned for appropriate reporting of urine culture and antimicrobial susceptibility testing using information obtained through LIS.
