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.

OBJECTIVE: This study was aimed to investigate of newborn babies sex ratio in Seoul Seong Ae hospital and review of future problem. METHODS: We reviewed retrospectively the 21,332 cases of deliveries in women visiting at Seoul Seong Ae hospital from Jannuary 1994 to December 2003 (10 year's period). We investigated 1st baby and 2nd baby sex ratio and in case of 3rd baby, subdividing then into tree groups (first and second are female, first and second are male, first and second are male and female). We arranged the data at the base of childbirth registers and patients' obligation records. RESULTS: The results were as follows, 1. The total sex ratio in last 10 years was 111.2:100 (male:female). 2. 1st baby sex ratio was 109.2:100. 3. 2nd baby sex ratio was 110.6:100. 4. 3rd baby sex ratio was 133:100. CONCLUSION: These findings suggest that unbalance of sex ratio in 3rd baby is extremely serious trend in this country and is expected a tremendous social problems in early 21th century.

BACKGROUND: In patients with myocardial infarction (MI) and chronic stable angina, the coronary flow reserve (CFR) is reduced not only in the region of myocardium perfused by the ischemia-related artery but also in the regions supplied by angiographically normal coronary arteries. The effect of myocardial stunning on the remote CFR is unknown, however. METHODS: In ten open-chest anesthetized dogs, left circumflex coronary artery was occluded for 15 minutes (myocardial stunning group, n=5) or for 30 minutes (MI group, n=5) and was followed by a reperfusion for 60 minutes. Before coronary occlusion and at 30 minutes and at 60 minutes after reperfusion, resting coronary blood flow (CBF) and maximal CBF after IV injection of each of adenosine (ADE) and acetylcholine (Ach) was measured with electromagnetic flow probe located in the proximal left anterior descending coronary artery. CFR was calculated as the ratio of maximal and resting CBF. RESULTS: At 30 minutes and 60 minutes after reperfusion, the remote resting CBF were significantly increased in both groups and the remote CFR was significantly decreased in both groups. The CFR of the MI group was lower than myocardial stunning group. The coronary vasodilator response to Ach was significantly lower than the response to ADE in both groups. CONCLUSION: After MI and myocardial stunning, there was severe coronary vasodilator abnormality in the remote myocardium and that was more marked after MI. The coronary vasodilator response to Ach was significantly lower than the response to ADE in both groups, suggesting endothelial dysfunction in remote myocardium.

Pulmonary alveolar proteinosis is characterized by the remittent or progressive accumulation of lipid-rich proteinaceous material within the alveolar sacs in the absence of inflammatory response. Whole-lung lavage is the only consistent treatment for pulmonary alveolar proteinosis. We have utilized whole-lung lavage for the successful treatment of a 62 year-old female patient with pulmonary alveolar proteinosis. There was no persistent complication during the procedure and the postanesthetic recovery except temporary fever and hypoxic event. The patient was symptomatically, physiologically, and radiologically improved within days after the procedures.
