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.

Comparative Study
BACKGROUND
Neurogenic bladder dysfunction is a major problem for spinal cord injury (SCI) patients not only due to the risk of serious complications but also because of the impact on quality of life. The main aim of this study is to compare the rate of urinary tract infection (UTI) associated with hydrophilic-coated catheters versus uncoated polyvinyl chloride (PVC) catheters among SCI patients presenting with functional neurogenic bladder sphincter disorders.
METHODOLOGY
This was a retrospective cohort study from 2005 to 2020 including adult male or female patients who have an SCI at least more than 1 month ago with neurogenic bladder dysfunction and were using intermittent catheterization (single-use hydrophilic-coated or the standard-of-care polyvinyl chloride uncoated standard catheters) at least 3 times a day to maintain bladder emptying.
RESULTS
A total of 1000 patients were selected and recruited through a stratified random sampling technique with 467 (47.60%) patients in the uncoated catheter arm and 524 (52.60%) in the coated catheter groups. The three outcome measures, namely: symptomatic UTI, Bacteriuria, and pyuria were significantly higher in the group using uncoated polyvinyl chloride (PVC) catheters compared to hydrophilic-coated catheters at the rate of 79.60% vs.46.60%, 81.10% vs. 64.69, and 53.57% versus 41.79% respectively. Males, elder patients, longer duration, and severity of SCI were associated with increased risk of symptomatic UTI.
CONCLUSIONS
The results indicate a beneficial effect regarding clinical UTI when using hydrophilic-coated catheters in terms of fewer cases of symptomatic UTI. Bacteriuria is inevitable in patients with long-term catheterization, however, treatment should not be started unless the clinical symptoms exist. More attention should be given to the high-risk group for symptomatic UTIs.

BACKGROUND
Urine leukocyte count under microscopy is one of the most frequently used routine screening tests for urinary tract infection (UTI). Nevertheless, it is observed that pyuria is lacking in 10-25% of children with UTI. This study aims to determine the factors related to pyuria-negative UTI in young infants aged under four months old.
METHOD
This retrospective cross-sectional study was conducted on 157 patients aged under 4 months old with UTI. All subjects had paired urinalysis and urine culture, which were collected via transurethral catheterization. According to the results of their urinalysis, the patients were then classified as UTI cases with pyuria and UTI cases without pyuria. The clinical characteristics and outcomes of both groups were analyzed.
RESULT
Among the 157 UTI patients, the prevalence of pyuria-negative UTI was 44%. Significant risk factors associated with pyuria-negative UTI included non-E.coli pathogens, younger age, shorter duration of fever prior to hospital visit, lower white blood cell (WBC) count upon hospital visit, and absence of microscopic hematuria.
CONCLUSIONS
We found that non-E.coli uropathogens were the strongest factor related to pyuria-negative UTI. The absence of pyuria cannot exclude the diagnosis of UTI in young infants, and it's reasonable to perform both urinalysis and urine culture as a part of the assessment of febrile or ill-looking young infants.

Pyuria in dipstick examination serves as the most widespread screening tool for urinary tract infections (UTI). The absence of pyuria, however, does not exclude UTI. We investigated the diagnostic value of urinary calprotectin, a mediator protein of the innate immune system, which is released by leukocytes, for the detection of UTI and compared it with dipstick pyuria. Since even low numbers of leukocytes in the urine significantly increase urinary calprotectin concentrations, calprotectin might be a more sensitive marker than pyuria detected by dipstick. All 162 patients were prospectively included and underwent a urine dipstick, urine culture, quantification of proteinuria and determination of calprotectin in the urine. Urinary calprotectin was determined using an enzyme-linked immunosorbent assay (ELISA). UTI was defined as urine cultures with detection of one or a maximum of two uropathogenic bacteria with ≥ 10 colony-forming units per millilitre (CFU/ml). Exclusion criteria were acute kidney injury, chronic renal insufficiency and tumors of the urinary tract. 71 (43.8%) patients had a UTI. Of the 91 patients without UTI, 23 had a contamination and 19 had evidence of ≥ 10 CFU/ml considered to be asymptomatic bacteriuria. The median calprotectin concentration in patients with UTI and pyuria was significantly higher than in patients with UTI and without pyuria (5510.4 vs. 544.7 ng/ml). In ROC analyses, calprotectin revealed an area under the curve (AUC) of 0.70 for the detection of significant bacteriuria. Pyuria in dipstick examinations provided an AUC of 0.71. There was no significant difference between these AUCs in the DeLong test (p = 0.9). In patients with evidence of significant bacteriuria but without pyuria, a significantly higher calprotectin concentration was measured in the urine than in patients with neither pyuria nor UTI (544.7 ng/ml vs 95.6 ng/ml, p = 0.029). Urinary calprotectin is non-inferior to dipstick pyuria in the detection of UTI.

INTRODUCTION
Bacterial urinary tract infections (UTI) and some sexually transmitted infections (STI) can have overlapping signs and symptoms or nonspecific findings, such as pyuria on urinalysis. Furthermore, results from the urine culture and the nucleic acid amplification test for an STI may not be available during the clinical encounter. We sought to determine whether gonorrhea, chlamydia, and trichomoniasis are associated with bacteriuria, information that might aid in the differentiation of STIs and UTIs.
METHODS
We used multinomial logistic regression to analyze 9,650 encounters of female patients who were aged ≥18 years and who underwent testing for STIs. The ED encounters took place from April 18, 2014-March 7, 2017. We used a multivariable regression analysis to account for patient demographics, urinalysis findings, vaginal wet-mount results, and positive or negative (or no) findings from the urine culture and testing for or
RESULTS
In multivariable analysis, infection with , or was not associated with having a urine culture yielding 10,000 or more colony-forming units per mililiter (CFU/mL) of bacteria compared with a urine culture yielding less than 10,000 CFU/mL or no urine culture obtained. The diagnosis of a UTI in the ED was not associated with having a urine culture yielding 10,000 or more CFU/mL compared with a urine culture yielding less than 10,000 CFU/mL.
CONCLUSION
After adjusting for covariates, no association was observed between urine culture results and testing positive for trichomoniasis, gonorrhea, or chlamydia. Our results suggest that having a concurrent STI and bacterial UTI is unlikely.

Review
OBJECTIVE
This study aimed to explore the global, prevalence, and risk factors of fever after percutaneous nephrolithotomy (PCNL) by conducting a systematic review and meta-analysis.
METHODS
The high-sensitivity searching was conducted without time limitation until December 30, 2020 in Web of Sciences, Scopus, and PubMed based on inclusion and exclusion criteria.
RESULTS
The prevalence rates of fever and sepsis among patient undergoing PCNL were estimated 9.5% (95% confidence interval [CI]: 9.3%-9.7%), and 4.5% (95% CI: 4.2%-4.8%), respectively. Nephrostomy tube was used in 9.96% (95% CI: 9.94%-9.97%) of patients. The mean preoperative white blood cells of patients were 6.401×10/L; 18.3% and 4.55% of patients were considered as the positive urinary culture and pyuria, respectively. About 20.4% of patients suffered from residual stones. The odds ratios (ORs) of fever in patients who suffering from diabetes mellitus, hydronephrosis, staghorn stones, and blood transfusion were 4.62 (95% CI: 2.95-7.26), 1.04 (95% CI: 0.81-1.34), 2.57 (95% CI: 0.93-7.11), and 2.65 (95% CI: 1.62-4.35), respectively. Patients who underwent PCNL in prone position were more likely to develop fever (OR: 1.23; 95% CI: 0.75-2.00) than patients in supine position.
CONCLUSION
The current study showed that patients who suffer from diabetes mellitus, hydronephrosis, staghorn stones, nephrostomy tube or double-J stent, blood transfusion, and also patients who underwent PCNL in prone position surgery are more likely to develop a postoperative fever after PCNL.

The introduction of immunotherapy has revolutionized the treatment and improved outcomes of multiple types of cancer. Although breast cancer is a less immune-responsive tumor type, the incorporation of pembrolizumab into chemotherapy regimens in the neoadjuvant and first-line metastatic setting for the triple-negative disease has improved outcomes. However, the use of this type of treatment is associated with a spectrum of adverse events. Although rarely affected, kidneys can be a target for immunotherapy, leading to irreversible injury if not recognized and addressed early. A 52-year-old woman presented with clinical stage II right breast cancer diagnosed at an outside facility. Neoadjuvant docetaxel/carboplatin/pembrolizumab every 3 weeks was started. Given the partial response on MRI after the 4th cycle, treatment was switched to doxorubicin/cyclophosphamide. However, pembrolizumab was held in cycle 2 due to the rash and then resumed in cycle 3 after the resolution of symptoms. Elevated creatinine was noted 3 weeks after the last dose of pembrolizumab without improvement despite adequate fluid resuscitation. Diagnostic workup was unremarkable except for pyuria and minimal albuminuria on urinalysis. In the absence of other risk factors and the temporal relationship between pembrolizumab administration and the onset of acute kidney injury (AKI), immune-related nephrotoxicity was the underlying diagnosis. After initiation of corticosteroids, creatinine decreased back to baseline without the need for kidney biopsy. An addendum to the original pathology report from the outside facility surfaced 5 months after starting treatment, revealing that the second breast lesion had a Fluorescence in situ hybridization (FISH) test performed that was positive. Given this fact, therapy was changed to two cycles of neoadjuvant paclitaxel/carboplatin/trastuzumab/pertuzumab, with approximately 8 weeks between the last pembrolizumab dose and the first dose of trastuzumab. Thereafter, she underwent a right breast mastectomy which showed residual invasive carcinoma with negative margins and lymph nodes. She completed 1 year of trastuzumab. Immune-related AKI is a rare, but potentially serious complication associated with an increase in mortality. Further research is needed in the development and early detection. There is promising research in the development of noninvasive biomarkers which has the added benefit of identifying patients who can be re-challenged with immunotherapy.

() 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.

A 53-year-old man with diabetes mellitus presented to the emergency department with a fever and impaired mobility. A preliminary diagnosis of urinary tract infection was made based on dysuria and pyuria. History-taking revealed a history of gait disturbance and difficult urination. A thorough physical examination suggested a spinal abnormality. MRI scan revealed a narrow spinal canal due to ossification of the posterior longitudinal ligament and diffuse idiopathic skeletal hyperostosis. Throughout the diagnostic process, we employed both vertical tracing to investigate the causes of urinary tract infection and horizontal tracing to explore comorbidities such as diabetes. Additionally, we introduced appropriate social security and support systems under the name of diagnostic excellence.
