The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.

In May 2023, the Committee of Clinical Practice Guidelines of the Korean Diabetes Association published the revised clinical practice guidelines for Korean adults with diabetes and prediabetes. We incorporated the latest clinical research findings through a comprehensive systematic literature review and applied them in a manner suitable for the Korean population. These guidelines are designed for all healthcare providers nationwide, including physicians, diabetes experts, and certified diabetes educators who manage patients with diabetes or individuals at risk of developing diabetes. Based on recent changes in international guidelines and the results of a Korean epidemiological study, the recommended age for diabetes screening has been lowered. In collaboration with the relevant Korean medical societies, recently revised guidelines for managing hypertension and dyslipidemia in patients with diabetes have been incorporated into this guideline. An abridgment containing practical information on patient education and systematic management in the clinic was published separately.

BACKGROUNDThe zotarolimus-eluting stent has shown larger in-stent late lumen loss compared to sirolimus-eluting stents in previous studies. However, this has not been thoroughly evaluated in ST elevation myocardial infarction.

METHODSThis was a prospective, randomized, controlled trial evaluating angiographic outcomes in patients presenting with ST elevation myocardial infarction, treated with zotarolimus-eluting stents or sirolimus-eluting stents. From March 2007 to February 2009, 122 patients were randomized to zotarolimus-eluting stents or sirolimus-eluting stents in a 1:1 fashion. The primary endpoint was 9-month in-stent late lumen loss confirmed by coronary angiography, and secondary endpoints were percent diameter stenosis, binary restenosis rate, major adverse cardiac events (a composite of cardiac death, non-fatal myocardial infarction, and target vessel revascularization), and late-acquired incomplete stent apposition.

RESULTSAngiographic in-stent late lumen loss was significantly higher in the zotarolimus-eluting stent group compared to the sirolimus-eluting stent group ((0.49 ± 0.65) mm vs. (0.10 ± 0.46) mm, P = 0.001). Percent diameter stenosis at 9-month follow-up was also larger in the zotarolimus-eluting stent group ((30.0 ± 17.9)% vs. (17.6 ± 14.0)%, P < 0.001). In-segment analysis showed similar findings. There were no significant differences in binary restenosis rate, major adverse cardiac events, and late-acquired incomplete stent apposition.

CONCLUSIONSCompared to sirolimus-eluting stents, the zotarolimus-eluting stent is associated with significantly higher in-stent late lumen loss at 9-month angiographic follow-up in the treatment of ST elevation myocardial infarction. Although there was no significant difference in 1-year clinical outcomes, the clinical implication of increased late lumen loss should be further studied.

The purpose of the study was to examine the adolescents' awareness and practice of Dietary Action Guide for Adolescence, which was developed by the Ministry of Health & Welfare. Subjects were middle and high school students, selected one class each from all of the 16 provinces in Korea, which were 32 schools and 998 students all together. The subjects were asked to self-evaluate the degree of awareness and practice of Dietary Action Guide using the 5 point-Likert scale from July to September, 2010. On average, 55.1% of the students responded that they were aware of the Dietary Action Guide and 49.4% answered that they put Guidelines into practice. The average score of awareness and practice were 3.54 +/- 0.24 and 3.42 +/- 0.33, respectively. The awareness score was higher than those of practice score in all the questions in the 6 categories. Awareness score of female students was higher than those of male students but there was no difference by residence area. Awareness and practice of the nutrition education-experienced were higher than those of the inexperienced. Practice score was higher among middle school-students compared to high school students, which reflected the opportunity of taking nutrition related classes. This finding shows that nutrition education for adolescents is important to change their dietary behaviors regardless of gender, residence area and school level.

PURPOSE: The goal of reduction mammaplasty is breast with natural cone shape, minimizing scars, well-placed and sensate nipple-areolar area and maintaining breast physiology. In order to satisfy that goal, variable reduction mammaplasty methods are performed, however, two methods such as vertical reduction method and inverted T-scar method are currently most used. We compared indications and advantages of the two methods and set up useful guidlines. METHODS: For 15 years from 1995 to 2010, we experienced 84 patients(162 breasts). We performed vertical reduction method as Lejour's superior pedicle technique(45 patients) and inverted T-scar method as Goldwyn's inferior dermal flap technique(39 patients). We evaluated the result of the operation comparing patient's age, amount of resected tissue, complications and post-operative scars of the two methods. RESULTS: The mean age was 36 years and the vertical reduction group was 3 years younger than inverted T-scar group. The mean breast tissue resection amount per one breast, inverted T-scar group(712 gm) was lagger than vertical reduction group(395 gm). CONCLUSION: There is no ideal method for reduction mammaplasty until now. However, we suggest that guide line, the vertical reduction method is effective for minimal and moderate macromastia in young and middle aged women and inverted T-scar method is appropriate for severe macromastia with ptosis in elderly women. Recently, all procedures tried shorter and smaller scar on the vertical line as small I, J or L shape scar, and inframammary fold as short inverted T-scar.

The present study investigated characteristics of 24 parasite infection cases detected during colonoscopy in a regional hospital from January 2001 to December 2008. Sixteen patients were confirmed with Trichuris trichiura infection, 6 patients were with Ascaris lumbricoides infection, 1 patient with Enterobius vermicularis infection, and 1 patient with Anisakis infection. Among them, 7 patients (43.8%) were asymptomatic. Colonoscopy findings were normal in 18 patients (75.0%). Among the patients with T. trichiura infection, colonoscopy showed several erosions in 2 patients (8.3%) and non-specific inflammation of the affected segment of the colon in 3 patients (12.5%). In 1 patient with anisakiasis, colonoscopy revealed a markedly swollen colonic wall. Stool examinations were performed before treatment in 7 patients (29.2%) and were all negative for parasite eggs or worms. These results suggest that colonoscopy is a useful diagnostic approach for parasitic infections even for asymptomatic patients and for patients with negative stool examinations.

PURPOSE: To perform an economic evaluation of the different treatment methods available for primary open-angle glaucoma in a Korean setting, including medication, selective laser trabeculoplasty, or surgery. METHODS: Three independent Markov chains were constructed for each treatment option to simulate treatment progress and to evaluate the total treatment costs for each initial strategy. The Markov chain consisted of different stages (5, 10, 20 stages), with each stage being one year. Assuming 1000 patients, a Monte Carlo simulation was iterated 1000 times to evaluate the cost of treatment over 5, 10 and 20 years. RESULTS: During the initial five years, medication as the initial treatment was the most expensive, whereas laser trabeculoplasty was the cheapest. After ten years, surgery became the cheapest treatment. In ten years, if the success rate of surgery is greater than 30.1%, it was more economic to choose surgery as the initial treatment. For laser trabeculoplasty, if the success rate was greater than 16.3%, laser treatment was more economical than was medication. Our model shows that only if the annual cost of medication decreases to 60,000 won or 55,000 won, then the cost of choosing medication as the initial treatment strategy will be more economical than that of laser therapy or surgery, respectively. CONCLUSIONS: The economic value of choosing laser therapy as the initial treatment strategy is the greatest over five simulated-years, whereas surgery had the greatest economic value over more than ten years.

Gastrointestinal angiodysplasia is one of the causes of acute and chronic gastrointestinal bleeding, and gastrointestinal angiodysplasia makes up 2~6% of all the cases of upper gastrointestinal bleeding. Bleeding from the ampulla of Vater is very rare. We report here on an unusual case of bleeding from angiodysplasia at the ampulla of Vater in a 58-aged woman with end stage renal failure. This lesion was successfully treated with endoscopic argon plasma coagulation.
