Obesity is a major nutritional problem in the developed countries. The prevalence of obesity may range from 10 to 50 per rent or mort of adult population and it may be increasing tendency. Many efforts have been made to understand the pathogenesis of obesity, but except a few metabolic obesities in the most of obese patients, the mechanisms are not understood. The treatment modalities of obesity, ranging from dietary and pubilc health intervention through the pharmacological and surgical therapy, have been developed and tested. In the obese patients mortalities and mobilities are significantly increased than non obese subjects due to hypertension, diabetics, and other problems. There are four possible mechanisms by which energy balance might be altered to enhance metabolic efficiency. futile metabolic pathway, alteration of protein rum over, alteration in sodium-potassium ATPase and alteration in uncoupled oxidation in brown adipose tissue are considered as possible mechanisms. Low calory and very low calory diets are recommended as a dietary program. Several pharmacological agent such as benzphetamine, fenfluramine, mazindol and fluoxetin are currently popular drugs for the treatment of obesity.

원저 : 복부비만이 있는 성인에서 혈장 아디포넥틴과 대사증후군의 구성요소와의 연관성

연구배경: 대사증후군은 인슐린저항성과 고인슐린혈증을 공통분모로 비만, 고혈압, 내당능장애, 이상지혈증 등을 동반하는 질환군으로 죽상경화증 및 심혈관질환의 위험요인이 되기 때문에 최근 주목받고 있다. 대사증후군의 주요병태생리인 인슐린저항성의 가장 중요한 원인으로 복부비만이 강조되고 있으며, 비만인에서 지방과 혈장의 아디포넥틴이 감소하는 것으로 알려지고 있다. 이에 본 연구에서는 복부비만이 있는 성인에서 혈장 아디포넥틴과 대사증후군의 다른 구성요소와의 연관성을 알아보고자 하였다. 방법: 2006년 5월부터 8월까지 중앙대학교병원 건강검진센터에 내원한 20세 이상의 성인 가운데 복부둘레가 대한비만학회(2005년)의 한국인 기준에 따라 남자는 90 cm, 여자는 85 cm 이상에 해당하는 110명을 대상으로 혈압, 혈청지질, 공복혈당, 인슐린, 아디포넥틴 농도 등을 측정하였다. 결과: 총 110명 중 남자는 65명(59.1%), 여자는 45명(40.9%)이었고, 연령은 23세에서 71세에 걸쳐 분포하였으며, 평균 연령은 48.02 ± 11.41세였다. IDF의 진단기준으로 대사증후군을 만족하는 대상자는 70명(63.6%), 그렇지 않은 대상자는 40명(36.4%)이었다. 공복 혈장 인슐린 농도와 HOMA-IR 값은 수축기 및 이완기혈압, 공복혈당이 증가할수록 유의하게 증가하는 양의 상관관계를 나타내었다. 공복 혈장 아디포넥틴 농도는 고밀도지단백 콜레스테롤 농도가 증가할수록 유의하게 증가하는 양의 상관관계를 나타냈으며 이때 고밀도지단백 콜레스테롤 농도가 독립변수인 것으로 나타났다. 결론: 대한비만학회의 복부비만 기준과 IDF의 대사증후군 진단기준을 사용하였을 때 대사증후군의 구성요소 가운데 저고밀도지단백 콜레스테롤혈증만 혈장 아디포넥틴 농도에 영향을 주는 독립변수인 것으로 나타났으며, 향후 복부비만의 개선 노력에 따른 혈장 아디포넥틴 농도의 변화와 대사증후군 구성요소와의 연관성에 대해 전향적 연구가 필요할 것으로 사료된다. Background: The metabolic syndrome is a constellation of interrelated risk factors of atherosclerosis and cardio-vascular disease. Abdominal obesity is emphasized as the most important cause of insulin resistance, which is the major pathogenesis of the metabolic syndrome. It is reported that adiponectin concentration in fat and plasma is decreased in obese individuals. In this study, we evaluated the association between plasma adiponectin and the components of metabolic syndrome in adults with abdominal obesity. Method: This study included 110 Korean adults with abdominal obesity (waist circumference ≥ 90 cm in men and ≥ 85 cm in women according to the criteria of Korean Society for the Study of Obesity, 2005), who visited to Center for Health Promotion in Chung-Ang University Medical Center. Their blood pressure, lipid profiles, fasting plasma glucose, insulin, and adiponectin concentration were measured. Results: A total 110 adults (aged 23-71 years, 65 men and 45 women) were included. Using the IDF criteria, number of individuals with metabolic syndrome was 70 (63.5%). Fasting plasma insulin concentration and HOMA-IR had positive correlation with systolic and diastolic blood pressure, and fasting plasma glucose concentration. In multivariate linear regression analysis, fasting plasma adiponectin concentration was mainly influenced by serum HDL cholesterol concentration. Conclusion: It is noted that low level of HDL cholesterol concentration was the only independent factor of fasting plasma adiponectin concentration. Further prospective studies regarding the association between the change in plasma adiponectin and the components of the metabolic syndrome after relieving abdominal obesity seem to be warranted.

Riedel's thyroiditis described by Bernhard Riedel in 1883, is rare chronic inflammatory diseases of unknown etiology and may be one manifestation of multifocal fibrosclerosis. The disorder presents with a history of painless anterior neck enlargement, which may gradually progress to produce symptoms of pressure, We reported a case of Riedel's thyroiditis in 61 years old man, He presented with painless swelling of the anterior neck with mild dysphagia. Physical examination revealed a stony hard, huge goiter and palpable cervical lymph nodes with mild tenderness. Surgical biopsy was done in thyroid mass and enlarged cervical lymph nodes. The histologic findings were diffuse dense fibrosis and inflammatory change replaced with normal thyroid tissue and severe necrosis with infarction of the lymph nodes. He was discharged while being treated with thyroxine and oral prednisolone. The thyroid mass and cervical lymphadenopathy were nearly resolved at three months of treatment. We think it may be the first report of the Riedel's thyroiditis that combined with cervical lymphadenopathy in Korea.

갈색세포종은 대부분 산발적으로 발생하고 다른 종양들과 연관되어 있으나 한 종양 내에서 갈색세포종과 신경절신경종이 동반되는 경우는 극히 드물다. 또한 다발내분비종양 제2형에서는 갈색세포종이 갑상선수질암과 관련되어 있으나 갑상선유두암과는 관련성이 드물고 이들간의 관계는 명백히 알려져 있지 않다. 저자들은 갈색세포종과 신경절신경종, 갑상선유두암이 동시에 발생한 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Composite tumors containing pheochromocytoma and ganglioneuroma are very rare. We report a 70-year-old female with papillary thyroid carcinoma and a compound adrenal medullary tumor, composed of pheochromocytoma/ganglioneuroma. She had complained of epigastric discomfort 2 months earlier. Chest computed tomography and pancreatic magnetic resonance imaging revealed an intrathoracic goiter and pancreatic cystic tumor. She underwent an explorative laparotomy, and a left adrenalectomy was done because of an adrenal mass, not the pancreatic mass. The pathological diagnosis was a compound adrenal medullary tumor, composed of pheochromocytoma and ganglioneuroma. Although there was no evidence of thyroid cancer on fine needle aspiration cytology, a total thyroidectomy was done because of the neck discomfort. The pathological diagnosis was a papillary thyroid carcinoma, and she underwent radioactive iodine therapy. (Korean J Med 76:85-89, 2009)

Chronic cough is defined as a cough that lasts for more than three weeks. In most patients, chronic cough is caused by four conditions: postnasal drip, asthma, chronic bronchitis, gastroesophageal reflux. Psychogenic chronic cough is not a frequent disorder. Furthermore, chronic vocal tic disorder is a very rare cause of chronic dry cough. A 22- year-old male suffered from chronic dry cough for last two years. His character showed obsessive- compulsive disorder. He has been shrugging both shoulders inadvertently since his childhood. Consequently, he was diagnosed as having chronic motor tic disorder. But after contracting respiratory tract infection, his motor tic disappeared and chronic dry cough was developed concomitantly. He had no history of smoking, chronic rhinitis, sinusitis, asthma, and gastroesophageal reflux. Physical examinations were normal. Chest X-ray, paranasal sinus view, metacholine bronchial provocation test, and esophago-gastroscopy were normal. Chronic cough was never relieved despite empirical treatment. Psychiatric consultation suggested chronic vocal tic disorder. The frequency of cough was diminished two days after administeration of valium and haloperidol and thereafter his complaint disappeared in one month. Here we report a very rare case of chronic motor tic disorder which was transformed into chronic vocal tic disorder presenting as a chronic cough. As far as we know, this is the first case of its kind in Korea.
