89 A Retrospective Study on the Emergency Department Outpatient Management of Pediatric Periorbital Cellulitis
Bibliographic record
Abstract
Periorbital cellulitis is an infection of the preseptal soft tissues that is often seen in a pediatric emergency department. Potential risks include progression to an orbital cellulitis and its complications. Prior to the introduction of the Hib vaccine in the mid 1980's, peri-orbital cellulitis was treated on an inpatient basis. Post Hib vaccine periorbital cellulitis is often treated as an outpatient, using broad-spectrum IV antibiotics. Emergency Department outpatient management is a safe method of treatment for children with periorbital cellulitis. A retrospective chart review was conducted on all cases with a discharge diagnosis of periorbital cellulitis extracted from visits to the Pediatric Emergency Department at Children's Hospital of Western Ontario from July 2000 to December 2002. Data collected included diagnostic criteria, physical findings, treatment type and duration, outcome and adverse outcomes. Stringent diagnostic criteria (SDC) of edema, erythema and fever (>38°C) were set as our diagnostic criteria of perior-bital cellulites although we reviewed all cases. Clinical treatment failure (CTF) was defined as a need to change route (PO to IV) and/or antibiotic choice or hospitalization. 87 cases of periorbital cellulitis were identified and reviewed. Of the 87 cases examined, 6 patients were admitted immediately and hence excluded. 16 (19.7%) cases met SDC, 65 cases did not. Fever was the absent symptom in over 90% of the cases that did not meet the SDC. Physical findings that would aid in the differential diagnosis of periorbital verses orbital cellulitis were not recorded in 24 to 68% of all patients. Blood and surface cultures were rarely positive or aided in therapy. Diagnostic imaging was rarely used, and only used in cases not responding to therapy. In the SDC, 6 were treated with oral antibiotics and 10 with IV antibiotics with no clinical failures with either treatment. In the non-stringent diagnostic group, 32 were treated with oral antibiotics and 33 with IV antibiotics. This group had 7 (10.8%) CTF with 2 on oral and 5 on IV. The average duration on IV antibiotics was 2.2 days and 8.3 days for oral antibiotics. The most common antibiotic prescribed for oral treatment was Keflex, whilst Cefuroxime was the most often used IV antibiotic therapy. The SDC for periorbital cellulitis are not universally applied. Indicators differentiating periorbital cellulitis from orbital cellulitis are not often documented. The outpatient management of periorbital cellulitis, with close follow-up, appears to be a safe practice with less than an 11% CTF rate.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
