We report herein infection in an 11-y-old, male llama with a history of diarrhea and endoparasitism. Postmortem examination revealed granulomatous and ulcerative enteritis, pyogranulomatous mesenteric lymphadenitis, fibrinosuppurative peritonitis, and granulomatous hepatitis. Intralesional macrophages were laden with gram-positive cocci. Bacteriology identified , and cultures tested positive for and genes by PCR. This case expands the reported spectrum of lesions associated with infections in llamas from pyogranulomatous bronchopneumonia and peripheral lymphadenitis to pyogranulomatous mesenteric lymphadenitis and enteritis. We also link a that is carrying the virulent-associated protein gene to clinical disease in New World camelids.

Eosinophilic gastroenteritis (EGE) is an inflammatory disease characterized by a significant increase in eosinophils. EGE itself is rare, and cases with clinical manifestations of hemorrhagic ascites are even rarer, which undoubtedly increases the risk of misdiagnosis. Given this, this study reports a rare case of pediatric EGE presenting with paroxysmal abdominal pain without apparent cause, accompanied by acute tonsillitis and mesenteric lymphadenitis, suggesting a possible intestinal infection.

: Anti PD1/PD-L1 agents, including pembrolizumab, have revolutionized the oncological treatment of different types of cancer, including non-small cell lung cancer. The most frequent complications associated with this type of treatment are mild and are located at the thyroid, pulmonary or hepatic level. Sarcoid like reaction and mesenteric panniculitis secondary to pembrolizumab treatment are two very rare adverse effects.

Introduction: Acute appendicitis (AA) is a prevalent cause of abdominal pain, and accurate diagnosis is critical to prevent complications such as perforation. While ultrasound (USG) is often the first imaging modality, its limitations necessitate alternative approaches, particularly in cases where USG results are negative.

Objectives And Aims: This study aims to evaluate the diagnostic accuracy of computed tomography (CT) in identifying appendicitis in patients presenting with negative USG findings.

Article Synopsis
  • The study examines cases of bovine abortions in South Korea caused by an opportunistic bacterium, focusing on its pathological findings, antimicrobial resistance, and genetic traits.
  • Three bovine abortion cases revealed severe lung issues and other infections, with bacterium detected in all affected fetuses; two were attributed solely to the bacterium, while one was associated with a viral coinfection.
  • This marks the first report of such abortions linked to this bacterium in South Korea, highlighting the need for ongoing research to understand its characteristics and resistance patterns.

Background: Mesenteric lymphadenitis (ML) demonstrates a distinctive inclination for the pediatric and adolescent demographic and the diagnosis of ML in young children poses a substantial challenge.

Objective: This prospective study aimed to assess the diagnostic efficacy of Superb Microvascular Imaging (SMI) and Virtual Touch Tissue Imaging quantification (VTIQ) in distinguishing pediatric mesenteric lymphadentitis.

Methods: We examined 82 mesentric lymph node (MLN) in pediatric patients with mesenteric lymphadentitis and 50 MLN in a healthy group.
