DCE short-case station: examination for tetany and latent hypocalcaemia — Chvostek and Trousseau technique with honest sensitivity, the calcium-focused history, presentation template and discussion.
Calcium-focused history — what you must establish
- The symptom pattern: perioral and digital paraesthesia, cramps, carpopedal spasm episodes, and red-flag neurological symptoms — stridor, seizures, syncope or palpitations (long QT) — plus their temporal relationship to the surgery [2].
- The surgical and endocrine context: indication for thyroidectomy, final histology (any parathyroid tissue in the specimen), voice change since surgery (recurrent laryngeal nerve), and whether calcium and PTH were ever checked post-operatively [2].
- The modifiers: current calcium/vitamin D therapy and adherence, PPI or diuretic use, alcohol, bowel symptoms suggesting malabsorption, menstrual and fracture history (chronic hypocalcaemia and vitamin D deficiency both speak to bone) [4] [5].
- The impact: work, driving (seizure and arrhythmia safety), mood and cognition — the quality-of-life burden of hypoparathyroidism is part of the assessment, not a soft extra [3].
