Multiple biliary papillomatosis involves an epithelial field change of the intrahepatic and extrahepatic portions of the biliary tree. Pathologically it is benign, occasionally with dysplasia, but the clinical behavior is regarded as having a low-grade malignant potential. Such malignancy is rare but the prognosis is poor if it is impossible to remove the tumor completely. Here, we report one case of multiple biliary papillomatosis in the biliary tree.

OBJECTIVE: The purpose of this study was to evaluate changes in bone quantity based on bone mineral density (BMD) and bone quality based on trabecular bone score (TBS) in Graves' disease patients after anti-thyroid therapy. RESEARCH DESIGN AND METHOD: This retrospective study included premenopausal female and male patients with Graves' disease who received BMD measurement more than two times during treatment. BMD and thyroid function tests with free thyroxine (FT4), total triiodothyronine (T3), thyroid stimulating hormone (TSH), and TSH receptor antibody (TRAb) levels were collected two times during follow-up. TBS was calculated using TBS insight® software (version 2.1) from dual-energy X-ray absorptiometry images. RESULTS: Thirty Graves' disease patients (17 males, 56%; 13 premenopausal females, 44%) with a mean age of 35.3 ± 9.9 years were included. The mean follow-up period was 20.7 ± 8.5 months. The median levels of FT4, TSH and TRAb improved at follow-up [2.55 ng/dL (Interquartile range (IQR) 2.07-3.78) to 1.28 ng/dL (IQR 1.23-1.39), 0.015 mIU/L (IQR 0.01-0.04) to 0.89 mIU/L (IQR 0.35-1.55), 17.0 IU/L (IQR 5.0-40.3) to 5.0 IU/L (5.0-6.0), respectively; p < 0.001]. Median BMD (lumbar spine) values also improved from 1.118 g/cm² (IQR 1.000-1.119) to 1.167 g/cm² (IQR 1.050-1.219) ( p = 0.001) at follow-up. TBS increased from 1.377 (IQR 1.299-1.422) to 1.390 (IQR 1.327-1.430) after treatment ( p = 0.038). CONCLUSIONS: Both bone quality and density improved after anti-thyroid treatment in premenopausal female and male Graves' disease patients.

PURPOSE: Paradoxical embolism due to the presence of patent foramen ovale(PFO) is a well-established possible mechanism of ischemic stroke of unknown origin, and the closure of PFO seems to be a kind of most effective method of the prevention of stroke recurrence. We report the initial and intermediate-term result of transcatheter closure of PFO associated with paradoxical embolism leading to cryptogenic transient ischemic attack or cerebrovascular accident using the Amplatzer(R) PFO Occluder. METHODS: From January 2003 through May 2005, 10 patients with PFO(4 male, 6 female) with history of at least 1 cryptogenic transient ischemic attack or cerebrovascular accident underwent percutaneous transcatheter closure of PFO using Amplatzer(R) occluder assisted by transesophageal echocardiography(TEE). All procedure were performed under general anesthesia and assisted by TEE. RESULTS: In all patients, the implantation procedure was successful and no significant complication was observed(in one case, peri-interventional ST-segment elevation observed). During the follow-up period of mean 13.1 months(range, 1-28 months), no recurrence of neurologic episode were observed and there was no residual shunt through PFO. CONCLUSION: We were able to implant the device without significant complication in all our patients and close PFO effectively. No recurrence of neurologic episode were observed. We conclude that in this initial and intermediate-term follow up, the transcatheter closure of PFO associated with paradoxical embolism using the Amplatzer(R) PFO Occluder is a safe and effective method in prevention of stroke recurrence and there is no significant adverse effect until now. And this procedure may be the treatment choice in patients with the high risk of recurrence ischemic attack. However, in this study, the number of patients included[5 patients(50%) had multiple thromboembolic events] is small and follow-up period is not long. So, we need more clinical cases and long-term clinical follow-up.

4.Advances in Continuous Glucose Monitoring: Clinical Applications
Endocrinology and Metabolism 2025;40(2):161-173
Continuous glucose monitoring (CGM) has revolutionized diabetes management, significantly enhancing glycemic control across diverse patient populations. Recent evidence supports its effectiveness in both type 1 and type 2 diabetes management, with benefits extending beyond traditional glucose monitoring approaches. CGM has demonstrated substantial improvements in glycemic control across multiple metrics. Studies report consistent glycosylated hemoglobin reductions of 0.25%–3.0% and notable time in range improvements of 15%–34%. CGM effectively reduces hypoglycemic events, with studies reporting significant reductions in time spent in hypoglycemia. CGM also serves as an educational tool for lifestyle modification, providing real-time feedback that helps patients understand how diet and physical activity affect glucose levels. While skin-related complications remain a concern, technological advancements have addressed many initial concerns. High satisfaction rates and long-term use suggest that device-related issues are manageable with proper education and support. Despite high initial costs, CGM’s prevention of complications and hospitalizations ultimately reduces healthcare expenditures. With appropriate training and support, CGM represents a transformative technology for comprehensive diabetes care.

Objectives:
The aim of this study was to examine the effect of cognitive behavioral therapy (CBT) and motivational enhancement therapy (MET) based psychoeducation with mindfulness meditation (PMM) on hazardous drinking (HD) and motivation for change.
Methods:
The participants were people who received order of lecture due to drunk driving. A total of 75 subjects participated in 6-session CBT/MET based PMM for 3 weeks as order of lecture program. Age, sex, and alcohol related problems (physical symptoms, occupational problem, economic difficulty, use of mental health service, and family conflict), HD, motivation for change and insight into HD, and depressive symptoms were assessed.
Results:
Compared with before the order of lecture program, the portion of those with HD significantly decreased (86.7% to 50.7%, pConclusions
This study demonstrated significant effects of CBT/MET based PMM on HD and motivation for change in drunk drivers. Our findings suggest that integrating approaches from CBT, MET, and mindfulness meditation can contribute to preventing and reducing HD.

PURPOSE: To examine the feasibility of endoscopic thyroidectomy (ET) via an axillo-breast approach without gas insufflation for large thyroid tumors and micropapillary carcinomas. MATERIALS AND METHODS: The patients in the benign group were separated into groups 1 (n=95, <4 cm in tumor diameter) and 2 (n=37, > or =4 cm in tumor diameter). Also, 57 patients in the micropapillary carcinoma group underwent an endoscopic hemithyroidectomy (HT) (group 3) and were compared with 60 patients who received conventional open HT (group 4). Postoperative functional outcome, local complications, surgical outcomes, and pathological outcomes were compared between the groups. RESULTS: In the benign group, there was no significant difference in mean operating time, hospital stay, or overall perioperative complications between the two groups. In the micropapillary carcinoma group, mean operating time and hospital stay in group 3 were significantly longer than in group 4 (p=0.015 and p< or =0.001). The overall perioperative complications did not differ significantly between the groups. The postoperative cosmetic result was better in groups 1-3 (endo group) than in group 4 (open group). CONCLUSION: ET via a gasless axillo-breast approach seems to be a safe procedure even for benign thyroid lesions > or =4 cm and micropapillary carcinomas. Although it has the advantage of better cosmetic results over open thyroidectomy, there is room for improvement in terms of lessening its invasiveness and shortening the operative time.

BACKGROUND: Several factors associated with human virologic failure in patients with immunodeficiency virus (HIV) infection are low CD4+ cell counts, advanced clinical stage, poor subscribing, subtherapeutic drug levels, etc. Among these factors, poor adherence is one of the leading causes. MATERIALS AND METHODS: We evaluated the adherence to antiretroviral treatment in HIV infected Koreans using questionnaire. We evaluated the factors associated with poor adherence and analyzed the correlation between the adherence to antiretroviral treatment and virologic failure. RESULTS: A total of 49 patients responded to the questionnaire. Of the 49 patients, 26 (53.1%) answered that they had never forgotten to take their medicine, and 23 (46.9%) answered that they had taken all their medications during the last week. The reasons for missed doses were forgetting, being too busy, having adverse side effects, etc. Low CD4+ T cell counts, longer duration of antiretroviral treatment, and longer duration of being diagnosed with HIV infection were associated with poor adherence in HIV infected Koreans (P<0.05). There was correlation between poor adherence and virologic failure in these HIV-infected Koreans (P<0.05). CONCLUSION: Because poor adherence induces treatment failure, monitoring adherence is very important for successful antiretroviral treatment. Questionnaire was a good method for monitoring adherence in HIV infected patients.
