Splenic flexure volvulus is the least common form of colonic volvulus. Preoperative radiological diagnosis is usually made presumptively, based on plain radiographs and/or barium contrast enema study in patients presenting with acute large bowel obstruction. We report a case in which multidetector computer tomography (CT) findings were diagnostic of this condition, thus highlighting the usefulness of multiplanar reformatting.

Background: Eosinophilic gastroenteritis (EG) can mimic
symptoms of common gastrointestinal (GI) disorders but
responds well to appropriate treatment. Accurate diagnosis
is central to effective management. Data on EG in Southeast
Asia is lacking. We aim to describe the clinical profiles and
treatment outcomes of adult patients with EG in a Singapore
Tertiary Hospital.
Materials and Methods: This retrospective study involved
archival search of patients with GI biopsies that showed
eosinophilic infiltration from January 2004 to December
2012. Patients’ clinical data from computerised hospital
records and clinical notes was reviewed. Diagnostic criteria
for EG included presence of GI symptoms with more than 30
eosinophils/high power field on GI biopsies. Patients with
secondary causes for eosinophilia were excluded.
Results: Eighteen patients with EG were identified (mean
age 52 years; male/female: 11/7). Fifteen patients (83%) had
peripheral blood eosinophilia. Seven patients (39%) had
atopic conditions. Most common symptoms were diarrhoea
and abdominal pain. Small intestine was the most common
site involved. Endoscopic finding was non-specific. Ten
patients were treated with corticosteroids (nine
prednisolone, one budesonide): eight patients (89%)
responded clinically to prednisolone but four patients (50%)
relapsed following tapering-off of prednisolone and required
maintenance dose. One patient each responded to diet
elimination and montelukast respectively. Half of the
remaining six patients who were treated with proton-pump
inhibitors, antispasmodic or antidiarrheal agents still
remained symptomatic.
Conclusion: Prednisolone is an effective treatment though
relapses are common. Small intestine is most commonly
involved. EG should be considered in the evaluation of
unexplained chronic recurrent GI symptoms.

Objective:
Bariatric surgery effectively treats non-alcoholic fatty liver disease (NAFLD). The glutamate-serine-glycine (GSG) index has emerged as a non-invasive diagnostic marker for NAFLD, but its ability to monitor treatment response remains unclear. This study investigates the GSG index's ability to monitor NAFLD's response to bariatric surgery.
Methodology:
Ten NAFLD participants were studied at baseline and 6 months post-bariatric surgery. Blood samples were collected for serum biomarkers and metabolomic profiling. Hepatic steatosis [proton density fat fraction (PDFF)] and fibroinflammation (cT1) were quantified with multiparametric magnetic resonance imaging (mpMRI), and hepatic stiffness with magnetic resonance elastography (MRE). Amino acids and acylcarnitines were measured with mass spectrometry. Statistical analyses included paired Student’s t-test, Wilcoxon-signed rank test, and Pearson’s correlation.
Results:
Eight participants provided complete data. At baseline, all had hepatic steatosis (BMI 39.3 ± 5.6 kg/m2, PDFF ≥ 5%). Post-surgery reductions in PDFF (from 12.4 ± 6.7% to 6.2 ± 2.8%, p = 0.013) and cT1 (from 823.3 ± 85.4ms to 757.5 ± 41.6ms, p = 0.039) were significant, along with the GSG index (from 0.272 ± 0.03 to 0.157 ± 0.05, p = 0.001).
Conclusion
The GSG index can potentially be developed as a marker for monitoring the response of patients with NAFLD to bariatric surgery.
