Purpose: Management of children with adhesive small bowel obstruction (ASBO) is often based on abdominal radiographs (AXR). Our purpose was to determine the significance of paucity of gas on initial AXR.
Methods: Retrospective, single center review of children with ASBO between 2011 and 2015. Analysis included chi-square, non-parametric tests and multivariate regression.
Results: Of 207 cases, 99 were operative. Initial AXR showed paucity of gas in 41% and gaseous loops in 59%. Paucity was more common in operative patients (49% vs. 32%, p = 0.01). At operation, 71% of patients with paucity had closed loop or high-grade obstruction, compared to 29% of patients with gaseous loops (p = <0.001).
Conclusion: For children with ASBO with paucity of gas on AXR, complicated obstruction (closed loop or high-grade) should be considered. In children with high clinical suspicion of complicated obstruction, additional imaging with CT or SBFT may clarify the clinical picture.

Background: The antioxidant and anticancer potential of natural compounds, particularly from medicinal plants, is increasingly being explored as alternatives to synthetic antioxidants and chemotherapeutics. Boascia coriacea (Pax) has been traditionally used for treating various ailments, including oxidative stress-related diseases and prostate cancer. However, there is a paucity of empirical evidence to validate the ethnomedicinal claims, hence this study.

Article Synopsis
- Nonocclusive mesenteric ischemia (NOMI) involves intestinal ischemia from spasms in small blood vessels, which can become life-threatening if not diagnosed and treated quickly.
- In this case, an 81-year-old man was diagnosed with NOMI after imaging showed signs of intestinal distress, leading to emergency surgery where ICG fluorescence was used to assess blood flow in the intestines.
- The use of ICG fluorescence allowed for the precise removal of ischemic areas, improving outcomes and suggesting that more research on this technique could enhance future diagnostics and treatment of NOMI.

Enhancing the predictability of radon flux in fractured environments, particularly in confined spaces, is a crucial step towards mitigating the profound health risks associated with radon gas exposure. However, previous models on fluid transport through fractured rock have focused on the relationship between radon flux and aperture in fractures and faults. However, there is paucity of understanding on the influence of rock geo-mechanical properties on radon flux.

Formaldehyde (HCHO) is a human toxin that is both a pollutant and endogenous metabolite. HCHO concentrations in human biological samples are reported in the micromolar range; however, accurate quantification is compromised by a paucity of sensitive analysis methods. To address this issue, we previously reported a novel SPME-GC-MS-based HCHO detection method using cysteamine as an HCHO scavenger.
