Case presentation: We report the case of a 38 year old lady who presented with severe hypocalcaemia following the administration of zoledronic acid. Her significant background history included vitamin D deficiency and sleeve gastrectomy three years ago. She had prolonged hypocalcaemia requiring IV calcium replacement for two months. Her prolonged hypocalcaemia was attributed to her vitamin D deficiency at the time of zoledronic acid infusion as well as her history of bariatric surgery. Conclusion: This case emphasises the importance of ensuring vitamin D levels are replete prior to zoledronic acid infusion and ensuring the calcium levels are checked frequently in patients with a history of bariatric surgery obtaining zoledronic acid.展开更多

So, the purpose of this study was to determine the frequency of postoperative hypocalcaemia after thyroid surgery in Omdurman military hospital (Jan.-July 2018). Materials & Methods: In this retrospective facility based cross sectional study, 124 files were reviewed, the recorded data were age, sex, residence, diagnosis, type of surgery & postoperative calcium level, data were collected by a designed pretested checklist, data were analyzed by SPSS version 20 by using frequencies & cross tabulations, for postoperative hypocalcaemia. Results: Majority of the patients were between 21 - 41 years 49.2%, majority of them were females 83.9%. 97.6% of them underwent total thyroidectomy, 25% of the patients developed postoperative hypocalcaemia, also we found that there was no relation between sex, type of thyroid surgery & development of postoperative hypocalcaemia (P > 0.001). Conclusion: Our research showed that 25% of the patients who underwent thyroid surgery developed postoperative hypocalcaemia.展开更多

Therefore, iPTH level assessment in the postoperative period can be used to predict the development of hypocalcaemia. The optimal time point to measure serum iPTH is important for the accurate prediction of hypocalcaemia. Aim: This paper aims to evaluate the ability of iPTH as an early predictive marker of hypocalcaemia and determine which time iPTH is more able to predict postoperative hypocalcaemia. Method: This prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, B中央人民政府, Dhaka, from July 2020 to December 2021, with 67 patients who underwent total thyroidectomy. iPTH levels were measured on the day before the operation and at 1 hour, 4 hours, and 24 hours after the operation. S.calcium levels were measured on the day before the operation and 1<sup>st</sup> postoperative day. All the data were compiled and sorted properly and were analyzed statistically. Results: Postoperative hypocalcaemia developed in 18 cases, with an incidence of 26.9%. Pearson correlation showed a significant correlation between postoperative iPTH at 1 hr, 4 h, and 24 hr with 1st postoperative calcium value. The Receiver operating characteristic (ROC) curve was processed for the postoperative iPTH at 1 hr, 4 h, and 24 hr. The sensitivity, specificity, cut-off value, and mean AUC found 93.9%, 94.4%, ≤14.0, 0.988;95.9%, 94.4%, ≤09.5, 0.993 and 91.8%, 94.4%, ≤11.0, 0.993 respectively. Conclusion: iPTH can be used as an early predictor of post-thy-roidectomy hypocalcaemia. 4 hr iPTH showed more sensitivity and specificity for a cut-off value near the laboratory reference range.展开更多
