Frequency of Pyloric Stenosis in Patients Presenting with Persistent Vomiting
Bibliographic record
Abstract
Introduction: Pyloric stenosis is an uncommon condition in infants characterized by abnormal thickening of the pylorus muscles in the stomach leading to gastric outlet obstruction. Clinically infants are well at birth. Then, at 3 to 6 weeks of age, the infants present with "projectile" vomiting which can lead to dehydration and weight loss. Objective: To determine the frequency of pyloric stenosis in patient presenting with persistent vomiting. Material and Method: This Cross Sectional Study was conducted in the department of Gastroenterology, ATH, Abbottabad from 5th October 2020 to 5th April 2021. A total of 115 patients of both gender with persistent vomiting for more than 5 days were included in the study. Abdominal ultrasound was done by a consultant gastroenterologist of three years post fellowship experience. Pyloric stenosis was noted. Results: Age range in this study was from 1 to 40 years with mean age of 6.226±6.62 years and mean duration of complaints was 9.869±3.76 days. Male patients were 88.7%% and females were 11.3%%. Pyloric Stenosis was observed in 93% patients. Conclusion: Our study concluded that that pyloric stenosis is 4 times more common in males compared to females and is more common among younger age groups as compared to adult patients.

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.
