Unilateral uterine torsion with a near-complete rip of the affected right horn in a parturient German shepherd bitch
Bibliographic record
Abstract
Intra-parturient uterine torsion is a rare condition in bitches with multifactorial aetiologies. It is a cause of obstructive dystocia and is difficult to diagnose with most imaging techniques. Medical management of dystocia in parturient bitches with oxytocin often result in uterine rupture with severe consequences on maternal and foetal health. A three-year-old German shepherd (31kg) bitch presented to the Veterinary Teaching Hospital (VTH), University of Ibadan, Oyo State, Nigeria was diagnosed, after a caesarean section, with intra-parturient right horn torsion (180-degrees intracornual and 360-degrees at the ovarian end) and a near-complete rip of the affected horn from the uterine body. Before presentation, the bitch was said to have whelped three puppies but discontinued apparently due to perceived uterine inertia even when injected with three doses of oxytocin by a caregiver. The bitch’s vital signs were abnormal and reflected signs of progressive shock. Haemogram showed severe anaemia, moderate neutrophilia with left shift, normal plasma protein level and platelet counts. An ultrasound examination revealed the presence of two foetuses in-utero but un-engaged at the bitch’s birth canal. Following patient’s stabilisation, a caesarean section unveiled an empty, involuting, left uterine horn, a 180 degrees intracornual twist of the right horn (separating the foetuses into two closed compartments) and a 360 degrees torsion at the ovarian end, which severely strangulated the vessels and ligament. The affected horn, vessels, and ligament were congested. The gravid horn was nearly ripped from the uterine body at the bifurcation. The torsion was corrected, foetuses evacuated and a hemi-cornuectomy performed. The bitch’s recovery was uneventful. The diagnosis and management of obstructive dystocia is a challenge, especially in poor resource settings. The option of surgical intervention should be considered as an emergency by both pet owners and clinicians to preclude further complications, including those caused by oxytocin.

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.
