Abstract
In order to evaluate the clinical manifestations, management and outcome of childhood LA, a retrospective chart review of 35 pediatric with LA from Semtember 1995 to Semtember 2010 was conducted. Among the 37 patients (20 males and 15 females), 51, 4% (18/37) were primary lung abscess and 49,6% (17/35) had underlying chronic diseases (secondary lung abscess). The predisposing factors of the primary group (n = 18) included 16 cases of respiratory tract infection and 2 with laceration wound. The underlying diseases in the secondary group (n = 17) included 11 cases of hematologic disorder (64,7%), 4 of congenital heart disease, and 2 each of hyperimmunoglobulin E syndrome. 14 patients underwent diagnostic tapping, including echo-guided aspiration (11 cases) and computed tomography-guided percutaneous needle aspiration (2 case). Positive yield rate from aspiration of lung abscess was 50% (7/14). Surgical intervention was performed in 10 of the secondary group and in 1 patient from the primary group. The pathogens were identified in 17 patients (49,6%): 5 with oral flora, 4 with Staphylococcus aureus plus other pathogens, 1 with S. aureus alone, 2 with Pseudomonas aeruginosa plus Proteus mirabilis, 4 with P. aeruginosa alone, and 1 with Aspergillus. The average duration of parenteral antibiotic use was 20 days. 2 cases (5.4%) died due to poor control of the underlying diseases, and 4 of the patients (10,8%) had sequelae (3 with bronchiectasis and 1 with lung fibrosis). Early percutaneous aspiration has an important role in identification of pathogens. Oral anaerobes and S. aureus are the core pathogens in primary lung abscess and gram-negative pathogens should also be considered in secondary LA.

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.
