Objective: The purpose of this study was to analyze the CT findings in 10 patients with abdominal actinomycosis to determine the appearance of lesions and the pattern of spread of the disease.
Materials And Methods: We retrospectively reviewed the CT findings in 10 patients with pathologically proved actinomycosis. Involved areas were the pelvis (n = 4), greater omentum (n = 3), liver (n = 2), and kidney (n = 1). Contrast-enhanced (oral and IV) CT scans were available in all patients. Unenhanced CT scans were also available in six patients.
Results: CT scans showed mostly solid masses with focal areas of diminished attenuation in seven patients and mostly cystic masses with thickened walls in three. CT findings confirmed the infiltrative nature of the disease, showing its tendency to invade across tissue planes and boundaries. Dense inhomogeneous contrast enhancement in the walls or solid components of masses was seen in eight patients. Minimal lymphadenopathy was seen in only two patients.
Conclusion: Although nonspecific, actinomycosis should be included in the differential diagnosis when CT scans show an infiltrative mass with unusual aggressiveness and dense inhomogeneous contrast enhancement, especially in patients with fever, leukocytosis, or long-term use of intrauterine contraceptive devices.

Retroperitoneal lymphangioma is exceptionally rare. We present a case of a 41-year-old asymptomatic patient with a large abdominal cystic mass detected on contrast-enhanced computed tomography (CT) scan, initially suspected to be pseudomyxoma peritonei. Laparoscopic exploration revealed a 30 x 30 cm multilocular cystic tumour originating from the retroperitoneum.

Background: Bowel trauma, encompassing injuries to the small and large intestine, represents a significant medical challenge due to its potential for morbidity and mortality. Management of bowel injuries remains surgical, but multiple factors influence the outcome in these patients. This study provides an in-depth analysis of the high-risk features of hollow visceral trauma in the ICU setting and the corresponding mortality rates, shedding light on the critical factors that influence outcomes in these cases.

Background: Endocrine hypertension is believed to be underestimated worldwide especially in the developing countries. There is a scarcity of publications on endocrine hypertension in sub-Saharan Africa. The aim of this study was to reflect the profile of patients with endocrine hypertension of adrenal/paraganglioma origin at Chris Hani Baragwanath Academic Hospital (CHBAH).

Purpose Of Review: To share current concepts and provide an overview of the contextual issues and nutrition practices in critically ill patients in resource-limited settings (RLSs)/low- and middle-income countries (LMICs). Most of the world's population reside in these settings which also carries the greatest burden of critical illness.
Recent Findings: There is a paucity of evidence on nutrition practice in critically ill patients in RLSs and international guidelines are largely based on evidence derived from high-income countries (HICs).

Here, we found that PMA1 expression was significantly increased in from patients with IBD compared to that in healthy controls. A Crispr-Cas9-based fungal strain editing system was then used to knock out PMA1 expression in .
