BackgroundMany health benefits of bariatric surgery are known and well-studied, but there is scarce data on the benefits of bariatric surgery on the thyroid function.ObjectiveWe aimed to make a meta-analysis regarding the impact of bariatric surgery on thyroid-stimulating hormone (TSH) levels, levothyroxine dose, and the status of subclinical hypothyroidism.SettingSystematic review and meta-analysis.MethodsPubMed, EMBASE, and Cochrane Library were searched up to December 2020 for relevant clinical studies. Random-effects model was used to pool results. Network meta-analysis was performed, incorporating direct and indirect comparisons among different types of bariatric surgery. Meta-regression analysis was performed to evaluate the impact of moderator variables on TSH levels and required levothyroxine dose after surgery. We followed the PRISMA guidelines for data selection and extraction. PROSPERO registry number: CRD42018105739.ResultsA total of 28 studies involving 1284 patients were included. There was a statistically significant decrease in TSH levels after bariatric surgery (mean difference = ?1.66 mU/L, 95%CI [?2.29, ?1.03], P < .0001). In meta-regression analysis, we found that the following moderator variables: length of follow-up, mean age, baseline TSH, and preoperative thyroid function, could explain 1%, 43%, 68%, and 88% of the between-study variance, respectively. Furthermore, subclinical hypothyroidism was completely resolved in 87% of patients following bariatric surgery. In addition, there was a statistically significant decrease of levothyroxine dose in frank hypothyroid patients following bariatric surgery (mean difference = ?13.20 mcg/d, 95%CI [?19.69, ?6.71]). In network meta-analysis, we found that discontinuing or decreasing levothyroxine dose was significant following Roux-en-Y gastric bypass, 1 anastomosis gastric bypass, and sleeve gastrectomy, (OR = 31.02, 95%CI [10.34, 93.08]), (OR = 41.73, 95%CI [2.04, 854.69]), (OR = 104.03, 95%CI [35.79, 302.38]), respectively.ConclusionsBased on our meta-analysis, bariatric surgery is associated with the resolution of subclinical hypothyroidism, a decrease in TSH levels, and a decrease in levothyroxine dose.  相似文献

A case of an eleven-year old girl with Behcet disease is presented. Non-surgical treatment of gingival overgrowth caused by the use of Cyclosporine was successfully treated. This case emphasizes the need for cooperation between the medical and dental professionals and the responsibility of dental professionals to lead the diagnosis of systemic diseases like Behcet.  相似文献

The present study compares periodontal parameters, caries, and levels of colony forming units (CFU) of bacteria from subgingival plaque of permanent teeth, to those of primary teeth examined 4 years previously. Six children who had periodontitis and 5 who had no periodontitis in primary teeth (groups A and B respectively) were examined. The microbial examination included the number of CFU of the total anaerobic count, Actinobacillus actinomycetemcomitans, Streptococcus mutans and Porphyromonas gingivalis. The differences in CFU values for the permanent teeth between groups A and B were not significant. Group A had significantly higher gingival inflammation values in the permanent teeth than group B. Permanent teeth had significantly higher CFU values of P. gingivalis than the primary teeth. Based on the present limited sample, the number of CFU from bacteria of the subgingival plaque of primary teeth are not an adequate predictor of periodontal disease or caries in the permanent teeth.  相似文献
