Propranolol therapy for infantile hemangioma is less toxic but longer in duration than corticosteroid therapy
Bibliographic record
Abstract
BACKGROUND: Infantile hemangioma is the most common benign, self-limiting tumour of childhood. Treatment is reserved for hemangiomas that obstruct vital structures or cause significant disfigurement. Traditionally, corticosteroids have been the medical treatment of choice. Since 2008, however, propranolol has been rapidly adopted as an effective pharmacological treatment for infantile hemangioma. Published data regarding the long-term side effects of propranolol are currently lacking. OBJECTIVE: To describe the long-term effects of propranolol and corticosteroids on anthropometric measurements (height, body mass index [BMI]) and blood pressure in children. METHODS: A prospective database analysis of all infantile hemangioma patient visits to the pediatric vascular abnormality clinic at the authors' institution between October 2007 and February 2012 was performed. Anthropometric measures (height and BMI) and blood pressure were analyzed. RESULTS: A total of 290 visits (119 patients) to the pediatric vascular abnormality clinic were reviewed. Of these, 18 patients received medical treatment and their anthropometry was analyzed. BMI percentile increased significantly in patients treated with corticosteroids (P=0.0039). Corticosteroid treatment also resulted in a significant decrease in height percentile (P=0.0078). Anthropometric measures did not cross percentiles in children treated with propranolol. A significant decrease in systolic blood pressure was noted in the propranolol group (P=0.03), but no hypotensive values were recorded. Median treatment duration was significantly longer when patients received propranolol (372 versus 133 days; P=0.0033). CONCLUSION: Propranolol for the treatment of infantile vascular abnormalities does not share the unfavourable effects on patient anthropometry that corticosteroids exhibit; however, a longer duration of therapy is required.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
