ABSTRACT
Background:Gastroesophageal reflux disease( GERD)that does not respond satisfactorily to standard proton pump inhibitor is defined as refractory gastroesophageal reflux disease( rGERD). Combined therapy is used to treat rGERD, however,the addition of baclofen is rarely studied. Aims:To investigate the efficacy of baclofen combined with esomeprazole and mosapride on rGERD. Methods:Seventy-two patients with rGERD from March 2013 to April 2014 at the First Hospital of Putian City were enrolled and randomly divided into group A and group B. Patients in group A were orally administrated with esomeprazole 20 mg bid + mosapride 5 mg tid + baclofen 5 mg tid. Patients in group B were treated with esomeprazole 20 mg bid + mosapride 5 mg tid. The treatment course was 8 weeks. The efficacy on symptoms, esophagitis under endoscopy and adverse effects were compared between the two groups. Results:After 8-week treatment, score of heartburn,regurgitation,retrosternal pain,dysphagia and overall symptom were significantly decreased in the two groups than before the treatment. The overall symptom alleviating rate was significantly higher in group A than in group B (90. 6% us. 70. 0%;χ2 =4. 585,P=0. 032). Esophagitis under endoscopy in the two groups was significantly improved, the effective rate was significantly higher in group A than in group B(93. 8% us. 75. 0%;χ2 =4. 500,P=0. 034). The main adverse effects of baclofen were somnolence,dizziness and fatigue,all the patients were well tolerated. Conclusions:Baclofen combined with esomeprazole and mosapride is an efficient option for rGERD.
ABSTRACT
Objective To predict the occurrence of hypoparathyroidism following total thyroidectomy. Methods In this study, 124 patients underwent total thyroidectomy, 46 for thyroid cancer and 78 for multinodular goiter, additional neck dissection was performed on cancer patients. Serum calcium and parathyroid hormone (PTH) levels were examined preoperatively and at 1 h, 1 d and 2 d postoperatively. The occurrence of postoperative hypoparathyroidism was observed. Receiver operating characteristic curve analysis was employed to identify the best indicator to early predict the occurrence of clinical hypocalcemic symptoms. Results Fifty-eight (46.8%) patients suffered from postoperative transient hypoparathyroidism, with 22 ( 47. 8% ) cases in thyroid cancer group and 36 ( 46. 2% ) in multinodular goiter group ( λ2 = 0. 033, P = 0. 857). One (0.8%) patient in cancer group had permanent hypoparathyroidism. 90 patients (72.6%) had postoperative hypocalcaemia, 58 (46. 8% ) had subnormal serum PTH levels, 40 (32. 3% ) had hypocalcaemia symptoms. Postoperative serum calcium (F=21. 358,P =0. 000) and PTH ( F = 18.253, P =0.000) levels decreased more in cancer group than in goiter group.Receiver operating characteristic curve analysis demonstrated that the percentage of serum PTH level decline at 1 h postoperatively was most predictive and 76. 6% decline was the best cut-off value for the occurrence of clinical hypocalcaemia symptoms ( area under the curve being 0.933 ) with a sensitivity of 89. 7% and a specificity of 87.9%. Conclusions Neck dissection added to total thyroidectomy can decrease the postoperative serum calcium and PTH levels more seriously, but may not increase the incidence of postoperative transient hyperparathyroidism. The percentage of serum PTH level decline at 1 h postoperatively predicts the occurrence of clinical hypocalcaemia symptoms.
