Fever of unknown origin is an important diagnostic challenge in pediatrics that requires a thoughtful approach. The differential diagnosis is broad and includes infectious, autoimmune, oncologic, neurologic, genetic, and iatrogenic causes. Infection remains the most common etiology, and uncommon presentations of infections are still more likely than classic presentations of rare conditions. We report a case of a retropharyngeal abscess in a toddler whose presentation is marked by a prolonged fever (>3 weeks). This case highlights the importance of close follow-up with serially repeated history and physical examinations to guide the evaluation of a patient with fever of unknown origin.

Purpose: Postoperative fever (POF)/urinary tract infection (UTI) is one of the most unpleasant and undesirable conditions for surgeons after retrograde intrarenal surgery (RIRS). RIRS is not recommended for any patient with a positive urine culture to avoid POF and UTI, but some patients may develop postoperative UTI even if the urine culture is sterile. This study investigated the predictive factors of fever and UTIs after RIRS.

Article Synopsis
- Brucellosis is a widespread zoonotic infection that primarily presents as fever but can impact various organs, with endocarditis being the leading cause of death.
- Proper culture techniques are essential for diagnosing Brucella infections due to the organism's fastidious nature, especially in areas with high prevalence.
- A case series of three patients with Brucella endocarditis demonstrated successful management through medical therapy and emphasized the need for accurate diagnostics and timely surgical intervention when necessary.

Background: Metagenomic next-generation sequencing (mNGS) is an effective method for detecting pathogenic pathogens of bloodstream infection (BSI). However, there is no consensus on whether the use of antibiotics affects the diagnostic performance of mNGS. We conducted a prospective clinical study aiming to evaluate the effect of antimicrobial treatment on mNGS.
