A Case of Organized Hematoma after Coblation Assisted Turbinoplasty / 대한이비인후과학회지

Organized hematoma of nasal cavity has been reported previously in several articles. However, few studies reported the cause of organized hematoma. Recently, 22-years-old male who underwent coblation associated turbinoplasty one year ago visited our clinic with symptom of nasal obstruction. He was diagnosed as organized hematoma in left maxillary sinus. We performed endoscopic sinus surgery and successfully removed it. Therefore, we report a case of organized hematoma origin from maxillary sinus after coblation associated turbinoplasty.

Correlation between Body Mass Index and Snoring Time in Obstructive Sleep Apnea Patients / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: This study was performed to elucidate the relationship between body mass index (BMI) and snoring time (ST) in patients with obstructive sleep apnea (OSA) using a portable sleep monitoring device. SUBJECTS AND METHOD: From May 2011 to December 2015, 492 patients whose apnea-hypopnea index (AHI) was more than 5 were enrolled. Subjects were classified into 3 groups on the basis of the AHI (mild=5≤AHI<15; moderate=15≤AHI<30; severe=30≤AHI). Using the multiple linear regression analysis, the relationship between ST and other variables (BMI, arousal index, O2 desaturation events, age and AHI) were measured in each group. RESULTS: There was significant association between ST and BMI, especially in the severe group (p=0.005). CONCLUSION: In the severe group, reducing BMI is important to improve ST.

Association between 5-HT2A Receptor Gene Promoter -1438A/G Polymorphism and Bipolar Disorder in a Korean Population / 신경정신의학

OBJECTIVES: This study was designed to investigate the association between 5-HT 2A receptor gene promoter -1438A/G polymorphism and bipolar disorder in a Korean population. METHOD: 5-HT2A receptor gene promoter -1438A/G polymorphism were typed with Polymerase Chain Reaction in 120 patients with bipolar disorder and 120 normal controls. RESULT: The distributions of the genotype in the bipolar disorder with A/A, A/G, G/G were 14 (12%), 66(55%), 40(33%), and in the controls were 30(25%), 59(49%), and 31(26%). The allele frequencies of the bipolar disorders with A and G were 94(39.2%), 146(60.8%), and in the controls were 119(49.6), and 121(50.4), respectively. There were significant differences in genotype distributions and allele frequencies of -1438A/G between patients with bipolar disorder and normal controls. CONCLUSION: These results suggest that 5-HT2A receptor gene promoter -1438A/G polymorphism may be related to the development of bipolar disorder in a Korean population.

Bile Duct Dilatation after Subtotal Gastrectomy in Stomach Cancer: Comparison with Gastroduodenostmy (BillothI) and Gastro Jejunosto my (Billoth II)

PURPOSE: To evaluate the incidence and degree of bile duct dilatation after partial gastrectomy due togastric cancer and to determine any differences between gastroduodenostomy (Billoth I) and gastrojejunostomy(Billoth II). MATERIALS AND METHODS: We retrospectively analyzed the follow up abdominal CT findings in 113patients who had undergone partial gastrectomy without truncal vagotomy or cholecystectomy. In all cases,preoperative abdminal CT findings showed no evidence of bile duct dilatation. Among 113 patients, 41 underwentBilloth I surgery, and 72 underwent Billoth II. No case showed clinical or radiological evidence of obstructivecauses of bile duct dilatation. Among these patients, we decided the criteria for dilatation when this was noted.The grade was either mild (3 -4 mm), moderate (5 -8mm), or severe (over 9mm), as measured at the centralintra-hepatic duct. Extra-hepatic duct dilatation was graded as mild (6 -8mm), moderate (9 -12mm) or severe (over13 mm). We analyzed serum bilrirubin and alkaline phosphatase levels. RESULTS: When the central intrahepatic ductwas measured, 78 of 113 patients(69 %) showed bile duct dilata-tion; 24 of 41 cases(58.5 %) were in the billoth Igroup and 54 of 72 (75 %) were the in Billoth II group. After measurement of the extra hepatic duct, 22 of41cases(53.6%) in the Billoth I group and 54 of 72 (75 %) in the Billoth II group were found to be dilated. Theresults showed a slightly increased incidence of bile duct dilatation in the Billoth, II group but this was notstatistically significant(p>0.05). In the laboratory, total, direct, and indirect bilirubin, as well as alkalinephosphatase levels, were measured. Higher levels were found in Billoth II than in Billoth I but all findings werewithin normal limits. CONCLUSION: Mild dilatation of the bile duct after partial gastrectomy was a not uncommonfinding, and there was no significant difference of incidence or degree of dilatation according to the procedureperformed. If a patient has no clinical symptoms, it appears that clinical it appears that clinical evaluationdoes not require fur-ther study.
