Background: Inflammatory bowel disease (IBD) is a chronic inflammatory immune-mediated condition that affects the gastrointestinal system and alters bone growth and bone mineral density (BMD). Here we aimed to study the prevalence and predictors of a low BMD in pediatric patients with IBD.Methods: This retrospective cross-sectional analytical study included pediatric patients with IBD in whom BMD was evaluated using dual energy X-ray absorptiometry of the total body and lumbar spine. Osteoporosis was defined as a BMD Z-score ≤-2, osteopenia as -2 to -1, and normal as >-1. Clinical and laboratory findings were compared between patients with and without osteoporosis.Results: Of the 48 patients, 30 (62.5%) were males, 35 (72.9%) had Crohn’s disease, and 13 (27.1%) had ulcerative colitis. The mean age at diagnosis was 9.9±2.8 years. The median age at the time of the BMD scans was 11.9 (interquartile range, 9.9–14.3) years. Total body BMD scans identified 13 (27.1%) and 16 (33.3%) patients with osteoporosis and osteopenia, respectively. Spinal BMD scans revealed that 17 (39.5%) and 14 (32.6%) patients had osteoporosis and osteopenia, respectively. A low body mass index (BMI) Z-score (p=0.038), ileocolonic disease location (p=0.008), and a low calcium level (p=0.008) were significant predictors of osteoporosis on the total body BMD scans. A low BMI Z-score (p=0.039), decreased hemoglobin level (p=0.018), low calcium level (p=0.033), and infliximab use (p=0.019) were significant predictors of osteoporosis on the spinal BMD scans.Conclusions: This study showed a high prevalence of low BMD among pediatric patients with IBD. A low BMI, ileocolonic disease location, low hemoglobin and calcium levels, and infliximab use were significantly associated with osteoporosis.

Sigmoid volvulus is frequently reported in the “volvulus belt” (Middle East, Africa, the Indian subcontinent, Turkey, and South America) and is the third leading cause of large bowel obstruction in North America. It is an uncommon problem in children and adolescents, and is rarely considered a diagnosis in this group. A high index of suspicion is necessary to diagnose sigmoid volvulus in children. We present a 13-year-old Arabian girl who came with features suggestive of intestinal obstruction. Plain abdominal film revealed classic omega (coffee bean) sign of sigmoid volvulus. The volvulus was successfully decompressed by means of a rectal tube in our emergency department. The next day during the same admission the volvulus recurred and was successfully decompressed by endoscopy. She was discharged home on her parents’ request; she presented again 1 month later. This time the volvulus could not be decompressed non-operatively, so she underwent sigmoidectomy with primary anastomosis. Postoperatively she developed paralytic ileus that resolved after 10 days. Following that she did well and was discharged home. She is still free of symptoms 1 year after the resection. Sigmoid volvulus is an uncommon problem in children and adolescents, and is rarely considered a diagnosis in this group as a cause of intestinal obstruction. Pediatric surgeons should maintain a high index of suspicion, in order not to miss this important diagnosis, as any delay in instituting treatment has a devastating effect on morbidity as well as mortality. Early diagnosis and prompt treatment confer an excellent prognosis.
