RESUMEN
OBJECTIVES: We developed clinical guidelines for the management of bone health in Rett syndrome through evidence review and the consensus of an expert panel of clinicians. METHODS: An initial guidelines draft was created which included statements based upon literature review and 11 open-ended questions where literature was lacking. The international expert panel reviewed the draft online using a 2-stage Delphi process to reach consensus agreement. Items describe the clinical assessment of bone health, bone mineral density assessment and technique, and pharmacological and non-pharmacological interventions. RESULTS: Agreement was reached on 39 statements which were formulated from 41 statements and 11 questions. When assessing bone health in Rett syndrome a comprehensive assessment of fracture history, mutation type, prescribed medication, pubertal development, mobility level, dietary intake and biochemical bone markers is recommended. A baseline densitometry assessment should be performed with accommodations made for size, with the frequency of surveillance determined according to individual risk. Lateral spine x-rays are also suggested. Increasing physical activity and initiating calcium and vitamin D supplementation when low are the first approaches to optimizing bone health in Rett syndrome. If individuals with Rett syndrome meet the ISCD criterion for osteoporosis in children, the use of bisphosphonates is recommended. CONCLUSION: A clinically significant history of fracture in combination with low bone densitometry findings is necessary for a diagnosis of osteoporosis. These evidence and consensus-based guidelines have the potential to improve bone health in those with Rett syndrome, reduce the frequency of fractures, and stimulate further research that aims to ameliorate the impacts of this serious comorbidity.

OBJECTIVE: Probiotics reduce intestinal inflammation in, and Lactobacillus GG (LGG) reduces pulmonary exacerbation rate cystic fibrosis (CF) patients. We intended to determine the effect of a mixed probiotic preparation on pulmonary exacerbations and inflammatory characteristics of the sputum in CF patients. STUDY DESIGN: A prospective pilot study of 10 CF patients with mild-moderate lung disease and Pseudomonas aeruginosa colonization, treated with probiotics for 6 months. Pulmonary function tests (PFT's), sputum cultures with semi-quantitative bacterial analysis, and sputum neutrophil count and interleukin-8 (IL-8) levels were compared to pre-treatment and post-treatment values. The rate of pulmonary exacerbations was compared to 2 years prior to the study. RESULTS: The exacerbation rate was significantly reduced in comparison to the previous 2 years and to 6 months post-treatment (P = 0.002). PFT's have not changed at the end of treatment and during 6 months post-treatment. No change in sputum bacteria, neutrophil count, and IL-8 levels was observed. CONCLUSION: Probiotics reduce pulmonary exacerbations rate in patients with CF. Probiotics may have a preventive potential for pulmonary deterioration in CF patients.

BACKGROUND: A polymeric diet rich in transforming growth factor-beta 2 used as a single nutrient has been shown to induce remission in 79% of children with Crohn's disease. OBJECTIVES: To summarize the experience of several pediatric gastroenterology units in Israel using a TGFbeta2-enriched polymeric diet (Modulen IBD) supplementation in children and adolescents with Crohn's disease. METHODS: In a retrospective study we reviewed the charts of 28 children with Crohn's disease (10 girls, 18 boys) who received, in addition to conventional treatment, Modulen IBD as a supplement to their regular nutrition. These children were compared with 18 children supplemented with standard polymeric formula (Ensure Plus) and 18 children without formula supplementation. We recorded clinical manifestations, growth, and the Pediatric Crohn's Disease Activity Index before and after initiation of the polymeric diet. RESULTS: The Modulen-treated children showed a significant decrease in PCDAI from 34.3 to 15.7 (P< 0.0001). A significant decrease in PCDAI was recorded also in the Ensure Plus group, from 35 to 22 (P= 0.02) but not in the non-supplemented group. Significant improvements in body mass index (P = 0.01) and erythrocyte sedimentation rate (P= 0.03) were recorded at follow-up (median 3.4 months) only in the Modulen IBD group. CONCLUSIONS: In this cohort of children with Crohn's disease, supplementation of the diet with Modulen IBD as well as supplementation with Ensure Plus was associated with a decrease in PCDAI. The children supplemented with Modulen IBD also showed improvement in BMI, suggesting an additional advantage of nutritional therapy in children with this disease.
