Are There Hallmarks of Child Abuse? I. Osseous Injuries
Bibliographic record
Abstract
Certain conditions have been considered hallmarks of child abuse. Such pathognomonic conditions have led to an inevitable diagnosis of inflicted injury. Forensic pathologists are faced with complex analyses and decisions related to what is and what is not child abuse. In this review, we examine the literature on the specificity of five conditions that have been linked to inflicted injury to varying degrees of certainty. The conditions examined include tears of the labial frena (frenula), cigarette burns, pulmonary hemorrhage and intraalveolar hemosiderin-laden macrophages as markers of upper airway obstruction, intraabdominal injuries, and anogenital injuries and postmortem changes. Analysis of the literature indicates that frena tears are not uniquely an inflicted injury. Cigarette burns are highly indicative of child abuse, though isolated cigarette burns may be accidental. Pulmonary hemorrhage is seen more commonly in cases with a history suggestive of upper airway obstruction, but is not diagnostic in an individual case. Hemosiderin-laden macrophages may be seen in cases with inflicted injuries and in natural deaths. Abdominal injuries may be seen in accidents and from resuscitation, though panreatico-duodenal complex injuries in children under five years of age are not reported to be seen in falls or resuscitation. The understanding of anogenital injuries is increasing, but misunderstanding of postmortem changes has led to miscarriages of justice.

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.
