AI Article Synopsis
- The study investigates the prevalence and risk factors for asymptomatic intestinal microsporidiosis among aboriginal school children in Kuala Krau District, Malaysia, highlighting a lack of understanding of its epidemiology.
- Sixty-nine out of 255 children tested positive for microsporidia, with most showing low to moderate levels of spore excretion, indicating a higher prevalence than previously recognized.
- Key risk factors identified include being 10 years old, using unsafe drinking water, and close contact with domestic animals, suggesting the need for improved hygiene, sanitation, and safe water sources in the community.
Article Abstract
The epidemiology and environmental factors affecting transmission of human microsporidiosis are poorly understood. We conducted the present study to determine the prevalence and risk factors associated with asymptomatic intestinal microsporidiosis among aboriginal school children in the Kuala Krau District, Pahang State, Malaysia. We collected stool samples from 255 school children and examined the samples using Gram-chromotrope Kinyoun stain. We also collected demographic, socioeconomic, environmental and personal hygiene information using a pre-tested questionnaire. Sixty-nine of the children was positive for microsporidia: 72.5% and 27.5% were low (1+) and moderate (2+) excretions of microsporidia spores, respectively. Univariate and multivariate analyses showed being aged 10 years (p = 0.026), using an unsafe water supply as a source for drinking water (p = 0.044) and having close contact with domestic animals (p = 0.031) were all significantly associated with microsporidial infection among study subjects. Our findings suggest asymptomatic intestinal microsporidiosis is common in the study population, more than previously reported. In the study population, control measures need to be implemented, such as good personal hygiene, proper sanitation and safe drinking water supply.

Background: Gastric mucosal heterotopia (GMH) is a rare, typically asymptomatic condition characterized by ectopic gastric mucosa in tissues outside the stomach. However, it can lead to severe complications, including small intestinal perforation. This case report highlights the unique clinical presentation of GMH-induced recurrent small intestinal perforations, which has been rarely documented.

Background And Aims: In coeliac disease, the clinical role of the urinary gluten immunogenic peptide is unclear. It has been suggested it can be a non-invasive marker of villous atrophy. Therefore, we present the largest cross-sectional clinical data in patients with coeliac disease to establish the diagnostic accuracy of the urinary gluten immunogenic peptide in identifying villous atrophy.

With improved surgical outcomes for non-ruptured abdominal aortic aneurysm (AAA), the primary objective has shifted toward the detection of asymptomatic AAA. Since ultrasonographic visualization from the anterior abdominal wall is often obstructed by intestinal gas, utilizing additional bilateral posterior approaches via the retroperitoneal tissue may be beneficial. This study investigates the feasibility of assessment using three approaches through computed tomography (CT) data analyses.

Trichobezoar or hairball in the proximal part of the gastrointestinal tract is a rare condition that occurs mainly in young and adolescent females. Since human hair is resistant to digestive enzymes and resistant to peristalsis, it easily accumulates between the folds of the mucosa. Over time, food and mucus accumulate within the hair, forming a compact mass that fills almost the entire lumen.

Accidental ingestion of foreign bodies during dental procedures is relatively common, with the potential for serious complications, including intestinal perforations and severe pulmonary disorders. Our case report describes the prolonged, asymptomatic retention of a swallowed hex driver in the small bowel of a 38-year-old male, managed conservatively over an extended period. The patient, with a significant medical history of depression, was undergoing a dental procedure involving implant-supported restorations when the incident occurred.
