Hypnotherapy in Pediatric Gastroenterology.

In several countries, gut-directed hypnotherapy is becoming an established and evidence-based treatment in pediatric gastroenterology. This article describes what hypnotherapy is, offers an overview of its effect in gut-brain disorders and explains its potential mode of action. Moreover, the use of hypnotherapy in other areas of pediatric gastroenterology, as a supportive tool to reduce pain, stress, depression, and anxiety and improve quality of life, will be also discussed. Guidance toward implementing hypnotherapy in clinical practice is provided, including examples of how you can explain hypnosis to patients with gastroenterological symptoms.

The Effect of Nutritional Therapy on Bone Mineral Density and Bone Metabolism in Pediatric Crohn Disease.

OBJECTIVES: Both the inflammatory burden of Crohn disease (CD) and corticosteroids have a negative effect on bone density. Exclusive enteral nutrition (EEN) avoids corticosteroids and promotes endoscopic healing. We aimed to explore the effect of nutritional therapy on bone health in pediatric CD. METHODS: This was a planned sub-study of a clinical trial enrolling children with new-onset mild-moderate CD. Children were randomized to either 6 weeks EEN followed by 6 weeks 25% partial enteral nutrition (PEN) or 6 weeks of 50% PEN with a CD exclusion diet followed by 6 weeks of 25% PEN with exclusion diet. Bone formation and resorption were measured at baseline, week 12 and week 24 by serum C-Propeptide of Type I Procollagen (CICP) and type I Collagen N-Telopeptide (NTX), respectively. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry (DXA) scan at baseline and week 24. RESULTS: Median CICP improved from 130 ng/mL (106-189) at baseline to 223 (143-258) at week 12 and 193 (143-252) at week 24 (P = 0.016 for both, n = 29 children). Median NTX remained unchanged (P = 0.45 and P = 0.45). Thirty-six children had DXA scans performed at diagnosis; 81% and 33% had z scores of <-1 and <-2, respectively. DXA z scores did not improve from baseline (adjusted total body less head [TBLH] BMD -1.62 ±â€Š0.87) to week 24 (-1.76 ±â€Š0.75; P = 0.30, n = 21 with both scans). CONCLUSIONS: Low bone density is common in new-onset mild-moderate pediatric CD. CICP, a sensitive marker of bone formation, improved following dietary intervention but this was not associated with improved BMD.

Unilateral optic disc swelling in a fighter pilot.

Optic disc swelling occurs when there is an obstruction to axonal transport at the level of the lamina cribrosa. This may result from compression, ischemia, inflammation, or metabolic and toxic etiologies. Some of these etiologies may be life threatening and others may be self-limited. Thus, differentiating the different etiologies is important, albeit often difficult. We present a case of a 25-yr-old high-performance fighter aviator who presented with unilateral optic disc swelling 2 d after an F-16 flight, in which decompression was suspected. Visual acuity of the affected eye was decreased to 20/25, with enlarged blind spot and shallow arcuate scotomata on visual field testing. Pupil function, brightness intensity, and color vision were normal. Marked swelling of the entire optic disc, retinal flame-shaped hemorrhages, and engorgement of the retinal veins were seen. Since decompression sickness with nitrogen bubbles obstructing the optic nerve head vasculature was suspected, he was treated with hyperbaric oxygen. He rapidly improved, recovering full vision function within 6 d. No concurrent disease was found on extensive investigation. He returned to high-performance aviation 3 mo after onset of symptoms. No recurrence was seen during 3 yr of follow-up.
