As dyslipidemia at a young age is a risk factor for cardiovascular disease in adulthood, the screening and management of dyslipidemia in children and adolescents might be an important health issue. This review deals with issues related to the prevalence, diagnosis, screening, and treatment of pediatric dyslipidemia.Current Concepts: In Korea, the prevalence of pediatric dyslipidemia was 19.7% between 2007 and 2009. Dyslipidemia was defined according to the guidelines of the Korean Society of Pediatric Endocrinology: total cholesterol ≥200 mg/dL, low-density lipoprotein cholesterol ≥130 mg/dL, triglycerides ≥130 mg/dL, high-density lipoprotein cholesterol <40 mg/dL, or non-high-density lipoprotein cholesterol ≥145 mg/dL.Discussion and Conclusion: We recommend universal screening tests for dyslipidemia at ages 9–11 years and 17–21 years. Diet and lifestyle modifications are essential in the treatment of dyslipidemia. In children aged ≥10 years with a poor response to lifestyle modification, drug therapy is recommended. Pediatric dyslipidemia should be diagnosed and treated properly to reduce adult cardiovascular diseases and improve quality of life in this age group.

Two cases of exercise-induced atrial fibrillation were diagnosed in 68 years old female and 47 years old male. They complained palpitation during exercise, and emotional upset for the last 5 years. There was no evidence of organic heart disease except mild hypertension in female patient. The atrial fibrillation was induced repeatedly by treadmill exercise test and intravenous infusion of isoproterenol. The beta blocker(atenolol 50mg po dialy) prevented the induction of atrial fibrillation during treadmill exercise. We report two cases of exercise-induced atrial fibrillation which is very rare and might be related to catecholamine.

To assess the likelihood of procedural success in patients with multivessel coronary artery disease, 46 consecutive patients (male 34, female 12, mean age 60+/-9 years) umderwent single or multiple site angioplasty. The clinical diagnosis of unstable angina was in 20(44%), stable angina in 10 and acute or old myocardial infarction in 16. Coronary angiographic findings of 2 vessel disease was in 38(83%), triple vessel disease in 8. Left ventricular function was generally well preserved (mean ejection fraction 65+/-12%, range 30-82%) and mean 2.0 stenosis per patient angic, lasty had attempted. Single vessel angioplasty (SVA) was performed in 13 and multivessel angioplasty (MVA) in 33. Procedural success was achieved in 79(86%) out of total 92 stenoses. Sixty-six(88%) out of 75 stenoses in MVA and 13(76%) out of 17 stenoses in SVA had procedural success respectively. According to angiographic morphology of lesions, procedural success of type A stenoses was 17/17(100%), type B stenoses 57/66(86%) and type C stenoses was 5/9(33%). In 13 failures included inability to pass the guide wire cross the lesion in 7, inability to guide the griding catheter in 2 and inability to dilate lesions in 4. Before and after angioplasty, treadmill test (modified Bruce protocol)could be performed in 29 patients. Total duration of exercise and maximal double product improved significantly from 8.5+/-2.3 minute 5188+/-2403 to 12.2+1.3 min., 23,062+/-4111 respectively (p<0.001). 17 out of 24 patients who had positive treadmill test before angioplasty showed negative conversion after procedure. Complications included dissection in 29, prolongd chest pain in 5, acute closure in 3, cardiac tamponade in 1 and ventricular fibrillation due to side branch oclusion in 1. Thus, coronary angioplasty in selected paients with multivessel coronary artery disease might be useful and have relatively good immediate results, but the long-term efficacies with other forms of treatment must be evaluated prospectively.

OBJECTIVES: This study was conducted to assess the development of posttraumatic stress disorder (PTSD) after occupational physical injuries and the risk factors in occupational accident patients for PTSD. METHODS: Forty-seven occupational accident patients with physical injuries were administered BDI, STAI I and II, SCL-90-R, IES and questionnaires for risk factors and Clinician-Administered PTSD Scale(CAPS). RESULTS: 1) 12 patients(25%) were diagnosed as PTSD. 2) The BDI, STAI I and II and IES scores are significantly high(<0.05) in PTSD group than non-PTSD group. 3) The subscales of SCL-90-R, with an exception of PAR subscale, showed higher scores(<0.05) in PTSD group. 4) The loss of consciousness(LOC) was only significant risk factor in the occupational accident-related factors(<0.05). CONCLUSION: The results of this study show the development of PTSD among occupational accident patients. The loss of consciousness(LOC) was the only signiticant risk factor for PTSD in occupational accident patients.

A notable secular trend in early puberty onset has been described over the past few decades. Also, the prevalence and incidence of precocious puberty is increasing not only in Korea, but also around the world. The manifestation of secondary sex characteristics before 8 years in girls and 9 years in boys is defined as precious puberty. The causes of precocious puberty can be classified as gonadotropin releasing hormone (GnRH)-dependent, also known as central precocious puberty (CPP), or GnRH-independent. Evaluation of patient with precocity requires detailed examination of the clinical manifestation, GnRH stimulation test, and imaging of the central nervous system if indicated. The standard treatment for CPP is GnRH agonist, which is beneficial for adequate pubertal development and preservation of final adult height. In this paper, we investigate the diagnosis and adequate treatment of CPP.

Multiple endocrine neoplasia (MEN) 2B is charaterized by tumors of endocrine glands, consisting of medullary thyroid carcinoma (MTC), pheochromocytoma and mucosal neuromas of the tongue, lips and other sites. Especially, MTC is the main cause of death in patients who have not received early prophylactic treatment, and MTC in MEN 2B represents more aggressive progress than that of MEN 2A. We encountered two cases of multiple endocrine neoplasia type 2B. One was a 13 month old boy who had familial history of MEN 2B without any symptoms, and the other was a 6-year old boy who manifested multiple mucosal neuromas of the tongue which had been aggravated in four months. Their genetic analysis revealed a point mutation 918th cordon in the RET proto-oncogene. Both of them underwent an operation for prophylactic total thyroidectomy and the 6 year old boy's specimen turned out to be thyroid medullary carcinoma. We encountered two cases of MEN 2B with prophylactic thyroidectomy by early diagnosis of RET proto-oncogene, and report the cases with review of literature.

PURPOSE: The aim of this study is to investigate the differences in clinical characteristics and disease process between autoantibody-positive and -negative patients with type 2 diabetes mellitus (DM). METHODS: We investigated 162 patients diagnosed as DM between January 2000 and July 2009. 120 were classified as type 1 and 42 as type 2 DM. The clinical and laboratory data were obtained from medical records, retrospectively. RESULTS: The age at diagnosis, average BMI and serum C-peptide levels were significantly higher in type 2 DM patients than in type 1 DM patients. Type 2 DM patients had a significantly higher family history of diabetes and less frequent ketonuria. There were no significant differences between autoantibody-positive and -negative type 2 DM patients in age at diagnosis, BMI, C-peptide levels, HbA1c levels or family history. During the follow-up period, C-peptide levels were lower in the autoantibody-positive group than in the autoantibody-negative group, while. HbA1c levels were higher in the autoantibody-positive group. However, these differences were not statistically significant. CONCLUSION: In autoantibody-positive type 2 DM patients, progressive loss of beta-cell function leads to reduced insulin secretion and poor glycemic control as the disease progresses, and some may be reclassified as slowly progressive type 1 DM. Ccntinued and careful follow-up is therefore needed.

This study was done to characterize the natural course of C-peptide levels in patients with type 1 diabetes and identify distinguishing characters among patients with lower rates of C-peptide decline. A sample of 95 children with type 1 diabetes was analyzed to retrospectively track serum levels of C-peptide, HbA1c, weight, BMI, and diabetic complications for the 15 yr after diagnosis. The clinical characteristics were compared between the patients with low and high C-peptide levels, respectively. The average C-peptide level among all patients was significantly reduced five years after diagnosis (P < 0.001). The incidence of diabetic ketoacidosis was significantly lower among the patients with high levels of C-peptide (P = 0.038). The body weight and BMI standard deviation scores (SDS) 15 yr after diagnosis were significantly higher among the patients with low C-peptide levels (weight SDS, P = 0.012; BMI SDS, P = 0.044). In conclusion, C-peptide level was significantly decreased after 5 yr from diagnosis. Type 1 diabetes patients whose beta-cell functions were preserved might have low incidence of diabetic ketoacidosis. The declines of C-peptide level after diagnosis in type 1 diabetes may be associated with changes of body weight and BMI.
