To study the prevalence of Helicobacter Pylori (H. pylori) infection, according to ethnicity, gender and endoscopic findings among the patients underwent the oesophago-gastro-duodenoscopes (OGDS) at gastroenterology endoscopy unit, Hospital Serdang, Selangor, Malaysia. The database of all whom underwent OGDS at the gastroenterology endoscopy unit, Hospital Serdang from 1st August 2010 to 31st July 2012 was collected and assessed, retrospectively. A total of 924 patients who underwent OGDS were analyzed for the H. pylori infection by using Campylobacter-like organism (CLO) test. 130 (14.07%) tested positive, and their data were further studied according to gender, ethnicity, age group, initial indication for OGDS and endoscopic finding. The prevalence rate among males was 15.15% (70/462), while it was 12.99% (60/462) among females. In terms of ethnics, H. pylori infection was commonly found among Indian and Chinese with prevalence rate of 25.13% (50/199) and 17.41% (51/293) respectively. These figures are significantly higher than the 6.01% (25/416) for Malays. The age group (31-50 years old) had the highest prevalence rate of H. Pylori infection, which is of 18.55% (41/221). No significant difference was observed among initial indications for OGDS. Erosions were the commonest finding in H. pylori positive group with rate of 51.54% (67/130). However, erosions were not uncommon in H. pylori negative group as well with the rate of 48.61% (386/794). H. pylori infection rate among Malaysians was generally low, with the highest rate in Indians, followed by Chinese and relatively low in Malays. No significant difference between the prevalence rate of H. pylori infection in male and that in female was found. Erosions were equally common in either H. pylori positive or H. pylori negative group. .

INTRODUCTIONIntravenous calcium gluconate has been used to prevent postoperative hypocalcaemia (POH) following parathyroidectomy for secondary hyperparathyroidism in chronic kidney disease (CKD).

MATERIALS AND METHODSRetrospective data were obtained for 36 patients with CKD stage 4 and 5 after parathyroid surgery, correlating albumin-corrected serum calcium with the infusion rate of calcium gluconate. Calcium flux was characterised along with excursions out of the target calcium range of 2 to 3 mmol/L. With this data, an improved titration regimen was constructed.

RESULTSMean peak efflux rate (PER) from the extracellular calcium pool was 2.97 mmol/h occurring 26.6 hours postoperatively. Peak calcium efflux tended to occur later in cases of severe POH. Eighty-one per cent of patients had excursions outside of the target calcium range of 2 to 3 mmol/L. Mean time of onset for hypocalcaemia was 2 days postoperatively. Hypocalcaemia was transient in 25% and persistent in 11% of patients.

CONCLUSIONA simple titration regimen was constructed in which a 10% calcium gluconate infusion was started at 4.5 mL/h when serum calcium was <2 mmol/L, then increased to 6.5 mL/h and finally to 9.0 mL/h if calcium continued falling. Preoperative oral calcium and calcitriol doses were maintained. Blood testing was done 6-hourly, but when a higher infusion rate was needed, 4-hourly blood testing was preferred. Monitoring was discontinued if no hypocalcaemia developed in the fi rst 4 days after surgery. If hypocalcaemia persisted 6 days after surgery, then the infusion was stopped with further monitoring for 24 hours.
