Grisel syndrome or atlantoaxial non-traumatic subluxation is a rare entity, poorly described in pediatric literature, although it is a pathology that usually appears in young children. The typical presentation is a torticollis with a previous surgical antecedent (mainly a surgery of the ear, nose, and throat area like adenoidectomy) or after an upper tract respiratory infection. A prompt diagnosis is essential for a successful evolution, and the treatment in most cases is conservative. We report a case of an 8-year-old girl with a typical evolution of this unusual complication. In our case, the most important element for diagnosis was the 3D CT scanner, and the treatment was conservative with a successful outcome. Pediatricians should be aware of this rare but potentially serious entity to establish the correct treatment and avoid complications.

Background/Aims: The goal of this study was to analyze the likelihood of patients undergoing Roux-en-Y gastric bypass (RYGB) to recover a normal daily food intake, and the possible influence of dietary and exercise habits on long-term weight loss. Methods: The sample included 107 morbidly obese postoperative patients with at least 1 year of follow-up. The data collected included anthropometry, dietary and exercise habits, and information on ingested food. The unpaired Student’s t test and the multivariate step-by-step regression were used in the analysis. Results: The mean preoperative BMI was 50.7 ± 11.8 kg/m², which had decreased at the moment of survey to 31.7 ± 5.4 kg/m². The mean % Excess of BMI Lost (%EBMIL) was 77.4 ± 23.7%. The nutritional components of diet were similar to those for the nonobese population. There were no significant differences in %EBMIL regarding number of meals, social habits, components of diet, or amount of exercise. The daily mean caloric intake (1,364 ± 293 kcal) was the only parameter significantly related to the %EBMIL outcome. More than 30% of the patients had intolerance to certain foods. Conclusion: Obese patients undergoing RYGB can establish a postoperative lifestyle and diet similar to the ideal. Only the daily amount of ingested calories demonstrated a statistically significant influence on weight loss over time.
