Gluten-free diet may improve obstructive sleep apnea-related symptoms in children with celiac disease.

BACKGROUND: Enlarged tonsils and adenoids are the major etiology of obstructive sleep apnea (OSA) in children. Lymphatic hyperplasia is common to both OSA and celiac disease. We aimed to investigate the effect of a gluten-free diet on OSA symptoms in children with celiac disease. METHODS: Children with celiac disease aged 2-18 years were prospectively recruited before the initiation of a gluten-free diet. Children with negative celiac serology who underwent gastrointestinal endoscopies for other indications served as controls. All participants completed a validated OSA-related symptoms questionnaire and the pediatric sleep questionnaire (PSQ) at baseline and 6 months later. RESULTS: Thirty-four children with celiac disease (mean age 6.6 ± 3.5 years) and 24 controls (mean age 7.3 ± 4.6 years, P = 0.5) were recruited. There were no significant differences in gender, body mass index or season at recruitment between the two groups. The rate of positive PSQ scores was higher (more OSA-related symptoms) in the control group compared to the celiac group, both at recruitment and at the 6-month follow-up (33.3% vs. 11.8%, P = 0.046, and 16.7% vs. 0, P = 0.014, respectively). PSQ scores improved significantly in both groups at the 6-month follow-up (P < 0.001 for both). Improvement was significantly higher in the celiac group compared to controls (0.1 ± 0.09 vs.0.06 ± 0.06, respectively, P = 0.04). CONCLUSIONS: Children with celiac disease had fewer OSA-related symptoms than controls, but the degree of improvement following the initiation of a gluten-free diet was significantly higher. These findings suggest that a gluten-free diet may improve OSA-related symptoms in children with celiac disease.

Informed consent for tonsillectomy: Do parents comprehend the information we provide?

OBJECTIVE: Informed consent is an important part of the surgical process. Based on our clinical experience, we hypothesized that parents providing consent for their children's tonsillectomy do not comprehend all the information that is given to them by the operating surgeon at the time of a conventional consent process. MATERIALS AND METHODS: Parents whose children were scheduled for tonsillectomy with or without adenoidectomy and/or tympanostomy tubes insertion were enrolled. Within one hour after the consent process, they were asked to complete a questionnaire designed to collect demographic data and to evaluate how much of the information that was given to them was actually understood. RESULTS: Ninety-seven parents were enrolled between October 2011 and March 2013. The average percentage of correct answers (score) for the 16 multiple-choice questions was 76.3%. The average scores were 84.8% for the native Hebrew-speaking parents and 71.9% for the parents whose first language was other than Hebrew (p < 0.01). The average scores were 83.3% for the parents who are healthcare system workers and 74.4% for those parents whose profession is not related to medicine (p < 0.05). Fifty parents (51.5%) responded incorrectly to at least one of two questions that we defined as essential: "What would you do if your child starts to bleed from the mouth" and "What kind of food is recommended for your child during the first week after the surgery". CONCLUSION: The current conventional method of obtaining informed consent for tonsillectomy is inadequate, as reflected by the low level of parental comprehension of essential information. Further studies which will evaluate methods for improving the consent process are highly warranted.

Adult vallecular cyst: thirteen-year experience.

OBJECTIVE: To assess the characteristics of adult vallecular cyst. STUDY DESIGN AND SETTINGS: A retrospective chart review from a university affiliated hospital. SUBJECTS AND METHODS: Clinical manifestations and airway management of 38 consecutive adult patients with vallecular cyst admitted between 1992 and 2004 were studied. RESULTS: Two distinct groups were identified: infected (n = 24) and noninfected (n = 14). Twenty-two (91.7%) patients of the former group had acute epiglottitis with an abrupt onset culminating in abscess formation in 19 (79.2%) and airway compromise in 9 (37.5%) compared with none in the noninfected group (P = 0.006). In 4 (18.2%) of 22 patients, the origin of the infected vallecular cyst was evident only after symptoms subsided. Three patients had recurrent acute epiglottitis. The noninfected group had a relatively prolonged mild clinical course. CONCLUSIONS: Two types of vallecular cysts were characterized. Abscess formation was the hallmark of adult infected vallecular cyst. SIGNIFICANCE: To improve patient care, endoscopic follow-up is advocated. In patients with recurrent episodes of acute epiglottitis, imaging is recommended.
