Congenital syphilis and hepatic infarction, a not previously reported association. A pediatric case report
Bibliographic record
Abstract
Congenital syphilis is caused by Treponema pallidum infection of the fetus during pregnancy. Symptoms are variable. While endothelial damage is common, it is not usually present in congenital cases. Here we report the case of a 42-day-old infant hospitalized due to an abdominal mass. Imaging studies confirmed the presence of an injury in the left lobe of the liver without mass effect. Biopsies showed changes compatible with infarction and neonatal hepatitis. The patient's and his mother's serologies confirmed the diagnosis of congenital syphilis, and he was treated with intravenous penicillin. The liver is protected from ischemic injury by its double irrigation, but the accumulation of harmful agents may have caused this unusual presentation. Three months later, the patient was symptom-free, and the control MRI showed atrophy of the left lobe, while the rest of the parenchyma was unchanged.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
