Neurologic complications of thiamine (B1) deficiency following bariatric surgery in adolescents.

BACKGROUND: The prevalence of obesity among children and adolescents is rising and poses a major health concern. Bariatric surgery is well established in adults and has become an option for adolescents. Thiamine (B1) deficiency is common following bariatric surgery in adults. It may present as Beri-Beri, Wernicke encephalopathy, or Korsakoff psychosis. OBJECTIVE: Our aim was to describe the clinical features, diagnosis, and treatment of adolescents who presented with B1 deficiency after bariatric surgery at one center, and to summarize the data from the literature. PATIENTS: Three adolescents with morbid obesity (two boys and one girl, aged 15.5 to- 17-years-old), presented at Schneider Children's Medical Center of Israel with progressive lower limb pain and weakness 2-3 month following a bariatric procedure (sleeve gastrectomy or narrowing of a bariatric band). The girl also had upper limb involvement and cerebellar signs. All three were non-compliant with micronutrient supplementation. After admission, they received intravenous B1 and oral multivitamin supplementation, and their symptoms improved considerably. CONCLUSIONS: Micronutrient supplementation following bariatric surgery is crucial to prevent deficiencies. In adolescents, compliance with micronutrient supplementation should be assessed before and after such surgery. Thiamine deficiency may cause polyneuropathy, among other symptoms. Treatment reduces the severity of neurological complications.

Preferred weight-related terminology by parents of children with obesity.

AIM: In order to improve weight-related discussion with patients and minimise their discomfort, the terminology used by medical staff should be carefully chosen. The aim of the study was to identify the most motivating weight-related terminology to use with children with obesity. METHODS: Focus groups were used to generate a list of 12 weight-related terms in Hebrew, sent by a questionnaire to parents of children and adolescents with obesity. Terms were graded according to how desirable, stigmatising, blaming or motivating they were perceived. We identified the most positive and negative weight-based terms and conducted linear regressions to predict child motivation to lose weight when positive terms are used. RESULTS: The least stigmatising and most motivating and desirable terms were 'unhealthy body weight' and 'unhealthy lifestyle'. Medical staff mostly used 'overweight', which was relatively inoffensive yet not very motivating. 'Fat/obese' ('Shamen') was the most stigmatising and blaming term and the least desired. Only 20% of parents endorsed a nonverbal graphical tool to describe body size. CONCLUSION: Our findings encourage using health-based terminology over weight-based terminology to promote treatment and lifestyle changes in children with obesity. Healthcare professionals should adopt patient-centred care and improve the weight-related terms they use with children with obesity.
