Clinicopathological findings and clinical outcomes in 49 cases of feline pemphigus foliaceus examined in Northern California, USA (1987–2017)
Bibliographic record
Abstract
BACKGROUND: Few studies have described the pathophysiology, clinical course, treatment outcomes and quality of life (QoL) of cats with pemphigus foliaceus (PF). OBJECTIVE: Describe clinicopathological features, treatment outcomes and impacts on QoL in feline PF. ANIMALS: Forty-nine client-owned cats with PF that presented to a veterinary teaching hospital between 1987 and 2017. METHODS AND MATERIALS: Medical records and histopathological reports were reviewed to obtain clinicopathological data and treatment outcomes. Owners were contacted and requested to complete a questionnaire to obtain long-term follow-up and evaluate the impacts of PF on QoL of cats and owners. RESULTS: Domestic short/medium/long hair breeds were most commonly affected, with pinnae, head, haired face, nasal planum and ungual folds most frequently involved. Associated pruritus and systemic signs of illness were common. Vasculopathological changes were noted in a small proportion of cats. Corticosteroid monotherapy was sufficient to induce complete remission in the majority of cats. Pemphigus foliaceus and its management had a negative impact on QoL of both cats and owners. Receiving/administering medications, attending veterinary appointments, and financial and time commitments were cited sources of stress for affected cats and/or owners. CONCLUSIONS AND CLINICAL IMPORTANCE: Results illustrate that affected cats generally respond favourably to treatment but do require long-term therapy. The exact aetiology of the vasculopathological changes was unclear; it may reflect the stage or severity of disease or suggest the presence of a cutaneous adverse drug reaction. Clinicians managing cats with PF should be aware of the potential negative impact on QoL of owners and cats and adjust management accordingly.

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.
