Abstract

fetched live from OpenAlex

Vitamin D deficiency is a major public health issue affecting large proportions of the population. Therefore, maternal vitamin D deficiency is not uncommon. Infants born to mothers who are deficient in vitamin D are at risk of developing vitamin D deficiency and hypocalcaemia. We reported here a case of neonatal hypocalcaemic seizures secondary to vitamin D deficiency. A 25-day old, full term male infant presented two episodes of generalized seizures. Laboratory investigations in blood, revealed low calcium level at 5.5 mg/dl, elevated phosphatemia level at 9.6 mg/dl and high parathormone (PTH) level at 133.4 pg/ml. Unfortunately 25 hydroxy vitamin D assay was not available in the infant but it was low in the mother at 12.9 ng/ml. The infant was commenced on vitamin D and calcium supplements during some weeks which allowed normalization of calcium levels. After several months of treatment cessation, the infant was doing well, and his development was according to his chronological. His calcium, phosphatemia and PTH levels were within normal ranges without any treatment. Hypocalcemia in this infant was presumably due to vitamin D deficiency as other causes were unlikely. Neonatal hypocalcaemic seizures are a rare presentation of vitamin D deficiency. This case could have been preventable had the mother been given vitamin D supplementation during pregnancy and early lactation.

Not 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.
