PURPOSE: We aimed to evaluate the difference in fluorodeoxyglucose (FDG) uptake in sedated healthy subjects after they underwent esophagogastroduodenoscopy (EGD) and colonoscopy procedures.METHODS: The endoscopy group (n = 29) included healthy subjects who underwent screening via F-18 FDG positron emission tomography/computed tomography (PET/CT) after an EGD and/or colonoscopy under sedation on the same day. The control group (n = 35) included healthy subjects who underwent screening via PET/CT only. FDG uptake in the tongue, uvula, epiglottis, vocal cords, esophagus, stomach, duodenum, liver, cecum, colon, anus, and muscle were compared between the two groups.RESULTS: Maximum standardized uptake value (SUVmax) in the tongue, pharynx, larynx, and esophagus did not significantly differ between the endoscopy and control groups. In contrast, mean SUVmax in the whole stomach was 18 % higher in the endoscopy group than in the control group (SUVmax: 2.96 vs. 2.51, P = 0.010). In the lower gastrointestinal track, SUVmax from the cecum to the rectum was not significantly different between the two groups, whereas SUVmax in the anus was 20% higher in the endoscopy group than in the control group (SUVmax: 4.21 vs. 3.50, P = 0.002). SUVmax in the liver and muscle was not significantly different between the two groups. Mean volume of the stomach and mean cross section of the colon was significantly higher in the endoscopy group than in the control group (stomach: 313.28 cm³ vs. 209.93 cm³, P < 0.001, colon: 8.82 cm² vs. 5.98 cm², P = 0.001).CONCLUSIONS: EGD and colonoscopy under sedation does not lead to significant differences in SUVmax in most parts of the body. Only gastric FDG uptake in the EGD subjects and anal FDG uptake in the colonoscopy subjects was higher than uptake in those regions in the control subjects.

Hashimotos thyroiditis has been associated with a various autoimmune disorders. The immunologic mechanisms involved in the pathogenesis of these disorders have not always been thought to be the same. Although it was demonstrated that there were high prevalence of abnormal thyroid function and autoantibody in autoimmune hemolytic anemia(AIHA) and Fisher-Evans syndrome(FES), AIHA combined with Hashimotos thyroiditis is rare in Korean literature. It was suggested that a common immunologic mechanism may be involved in the pathogenesis of both disease and the possibility of multiple autoimmune syndrome might present in autoimmune hematologic disorders. We experienced a 74-year old woman with a 12-year history of a hypothyroidism due to Hashimotos thyroiditis was hospitalized with sudden development of warm AIHA with positive Direct & Indirect Coombs test and pericardial effusion. Her thyroid function test showed subclinical hypothyroidism with the maintenance dosage of levothyroxine(100pg/day). With glucocorticoid and plasmapheresis, AIHA and pericardial effusion were corrected successfully. It is suggested that the prudent immunologic study is needed for the anemia developed in patients with Hashimotos thyroiditis with or without hypothyroidism.
