Objectives: The aim of this study was to describe the clinical characteristics of enuretic children and to evaluate the efficacy of treatments. Methods: Our study subjects enrolled were 52 children with nocturnal enuresis, who visited outpatient clinic of pediatrics in Seoul Paik Hospital and Ilsan Paik Hospital, during the period from October 1998 to August 2004. The data of gender, age, family history, symptom, clinical type of enuresis and drug therapy were collected and analyzed retrospectively. Results: The male : female ratio was 2.25 : 1. The mean age at diagnosis was 6.8 years with an age range from 4.3 years to 12.5 years. Fourty five cases(86.5%) were diagnosed as primary enuresis and 7 cases(13.5%) were diagnosed as secondary enuresis. A family history of enuresis was noted in 5 cases(9.6%) including 4 cases with parental enuresis history. The accompanying urinary symptoms were urgency(11.5%), frequency (7.7%), and dysuria(2.0%). Conclusion: We found frequent occurrences of enuresis in boys and primary type and an occasional association with a family history of enuresis. The two main treatment modalities were behavior control with an alarm system and drug therapy with imipramine, desmopressin, or oxybutynin. We recommend continuous drug medications to control nocturnal enuresis along with encouragement.

An epidemiological survey was conducted to estimate the prevalence of and identify the risk factors of dementia and depression in the elderly between December 1997 and August 1998 in Yonchon County, Korea. A total of 1,037 elderly aged 65 years and over underwent a two phase diagnocstc procedure. Multiple stage, random cluster sampling method was used to select the subjects. Response rate was 85.4%. For the Ist stage screening survey, the Korean Psych-ogeriatric Assessment Scale was used as a primary screening tool, which had already been standardized in Korea, and functioning and social support were assessed by ADL, IADL and APGAR. At the 2nd stage, diagnoses were confirmed according to the DSM-Ⅲ-R. And several other scales were used as supporting information for differential diagnoses and for evaluating severity. 1) Age-sex adjusted prevalence(%)[95% C.I] of dementia was 6.83[6.12-7.54](male 6.34 [5.29-7.40], female 7.09[6.14-8.04]). Prevalence of the dementia of the Alzheimer's type was 4.17[3.61-4.74](male 2.42[1.76-3.08], female 5.31[4.48-6.14]) and that of the va-scular dementia was 2.38[1.95-2.81](male 3.46[2.67-4.25],female 1.63[1.16-2.10]). 2) Age-sex adjusted prevalence(%)[95% C.I.] of depressive disorder was 10.99[10.11-11.87](male 7.59[6.44-8.73], female 1346[12.20-14.73]. Among depressive disorders, prev-alence(%)[95% C.I.] of major depressive disorder was 7.50[6.76-8.26](male 4.42[3.54-5.31], female 9.78[8.68-10.88]), that of dysthymic disorder was 2.02[1.62-2.42](male 1.37[0.86-1.87], female 2.46[1.88-3.03]) and that of depressive disorder NOS was 1.49[1.15-1.83](male 1.85[1.47-2.23], female 1.28[0.96-1.60]). 3) Five statistically significant risk factors of the dementia of the Alzheimer's type were identified : age over 85(O.R. = 10.27), illiteracy (O.R. = 4.01), alcohol abuse (O.R. = 2.98), smoking [0 < pack year ≤30(O.R. = 3.11), pack year>30(O.R. = 4.60)] and family history of dementia (O.R. = 4.85). 4) Three statistically significant risk factors of the vascular dementia were identified : illiteracy (O.R. = 3.78), history of CVA(O.R. = 26.76) and smoking over 40 pack year(O.R. = 11.15). 5) Three statistically significant risk factors of the depressive disorder were identifed : age between 75 and 79(O.R. = 2.87), past history of CVA(O.R. = 3.33) and family history of depressive disorder(O.R. = 7.16).

면역방사계수법을 이용한 Thyroglobulin 측정시 항 Thyroglobulin 항체의 존재가 미치는 영향

안병철,배진호,정신영,박호용,김정국,하승우,이재태,김보완,이규보 대한내분비학회 2004 Endocrinology and metabolism Vol.19 No.1

연구배경: 혈청 thyroglobulin (Tg)은 옥소전신스캔과 함께 분화갑상선암환자에서 갑상선암 재발에 대한 추적관찰에 매우 예민하고, 중요한 표지자로 임상에서 널리 이용된다. 그러나 많은 수의 분화갑상선암환자는 Tg 항체인 항 Tg 항체를 가지고 있고, 이는 방사면역검사법 (radioimmunoassay) 및 면역방사계수 검사법(immunoradiometric assay)으로 Tg 측정시 영향을 미칠 수 있다. 이에 연자들은 면역방사계수법으로 Tg를 측정할 경우, 항 Tg항체에 의하여 어떤 영향이 생길수 있는지를 알아보고자 하였다. 방법: 이중위치 고상법 (solid phase two-site)법을 이용하는 ELSA-hTg in vivo test (CIS international, Schering, France) 시약을 이용하여 Tg를 측정하였다. Tg과 항 Tg 항체는 검사시약에 포함된 표준용액을 사용하였으며, Tg는 두 가지 농도 (23.5 ng/mL, 62.5 ng/mL)로, 항 thyroglobulin 항체는 세 가지 농도(25U/mL, 50U/mL, 100U/mL)로 이용하였다. Tg가 높게 나타나는 환자의 혈청에 항 Tg 항체가 높게 나타나는 환자의 혈청을 혼합하여 동일한 방법으로 Tg 검사를 시행하였다. 통계학적 분석은 ANOVA와 Scheffe test 및 Quadratic regression modeling을 시행하였다. 결과: 면역방사계수법을 이용한 Tg 측정시 항 thyroglobulin 항체가 존재하는 경우 그 값이 낮게 측정되었다. Tg 농도가 23.5 ng/mL인 표준용액이 항 Tg 항체의 농도가 0, 25, 50 및 100U/mL 경우, 각각 24.5±1.1, 11.8±0.4, 7.7±0.1 및 4.5±0.4ng/mL로 측정되었으며, Tg 농도가 62.5 ng/mL인 표준용액은 각각 65.9±5.7, 36.3±2.2, 23.7±0.7, 및 14.0±1.0 ng/mL로 측정되었다(ANOVA test, p=0.000). 항 Tg 항체에 의한 Tg 측정값의 저하 정도는 항 Tg 항체의 농도에 비례하는 것으로 나타났다 (Quadratic model regression, SigT=0.000). 결론: 분화갑상선암환자에서 항 Tg 항체의 존재는 면역방사계수법을 이용한 혈청 Tg 측정으로 갑상선암 재발을 파악하는데 방해하는 인자로 작용될 수 있으며, Tg 측정시 항 Tg 항체의 측정이 꼭 필요하며, 항 Tg 항체를 가진 분화갑상선암환자에서 Tg 수치를 해석할 경우 세심한 주의가 요구된다. Background: Serum thyroglobulin (Tg) is a valuable and sensitive tool needed in the follow-up of patients with differentiated thyroid cancer (DTC), but antithyroglobulin antibody (Anti-Tg), common in patients with DTC, can interfere with the assay for Tg. In this study, we evaluated the influence of Anti-Tg on the measurement of Tg using the immunoradiometric assay (IRMA). Methods: In using ELSA-hTg in vivo test (CIS international, Schering, France), a solid phase two-site IRMA was used to measure Tg (23.5 ng/mL, 62.5 ng/mL) under the absence or presence of three concentrations of Anti-Tg (25U/mL, 50U/mL, 100U/mL). We also performed Tg measurement using patients serum that was mixed with patients serum containing high Anti-Tg. ANOVA and Scheffe tests were performed to evaluate the effect of Anti-Tg on Tg IRMA, and an inverse regression was made to calculate the level of Tg from measured Tg and used Anti-Tg levels and also to assess the degree of effect of anti-Tg on Tg IRMA. Results: In measuring Tg using the standard solution, the presence of Anti-Tg resulted in a falsely suppressed Tg value. The IRMAs for 23.5ng/mL of the standard Tg solution resulted in 24.5±1.1 ng/mL under no Anti-Tg, 11.8±0.4 ng/mL under 25U/mL of Anti-Tg, 7.7±0.1 ng/mL under 50U/mL of Anti-Tg, and 4.5±0.4 ng/mL under 100U/mL of Anti-Tg. IRMAs 62.5 ng/mL of the standard Tg solution resulted in 65.9±5.7 ng/mL under no Anti-Tg, 36.3±2.2 ng/mL under 25U/mL of Anti-Tg, 23.7±0.7 ng/mL under 50U/mL of Anti-Tg, and 14.0±1.0 ng/mL under 100U/mL of Anti-Tg. (ANOVA test, p=0.000). The degree of suppression of the measured Tg value was positively correlated with the Anti-Tg level (Quadratic model regression, Sig T=0.000). The presence of Anti-Tg also resulted in a falsely suppressed Tg value for the Tg measurement using patient's serum. 2004). Conclusion: The presence of Anti-Tg could consist of the use of Tg as a tumor, therefore Anti-Tg should be measured in all patients diagnosed with DTC. The interpretation of the Tg level must be performed with extreme caution in patients with Anti-Tg (J Kor Soc Endocrinol 19:42∼47, 2004)

Kim, Choongki,Hong, Sung-Jin,Shin, Dong-Ho,Kim, Jung-Sun,Kim, Byeong-Keuk,Ko, Young-Guk,Choi, Donghoon,Jang, Yangsoo,Hong, Myeong-Ki Oxford University Press 2015 European heart journal cardiovascular Imaging Vol.16 No.12

<P><B>Aims</B></P><P>We sought to evaluate whether coronary computed tomographic angiography (CCTA) could accurately and reproducibly delineate the lumen and vessel contours of coronary arteries.</P><P><B>Methods and results</B></P><P>One hundred coronary stenotic lesions representing 91 patients with stable angina who received both CCTA and intravascular ultrasound (IVUS) were analysed. Three segments with minimal lumen cross-sectional area (CSA), proximal reference, and distal reference on IVUS images were selected for each lesion. Five observers measured lumen and vessel CSAs at three matching segments on CCTA images. These CSAs were compared with the IVUS-measured CSAs as a reference standard. All five observers underestimated lumen CSA at the three selected segments by CCTA. The minimal lumen CSA assessed by CCTA exhibited very weak correlations with those obtained by IVUS (<I>r</I> =0.23, 0.24, 0.15, 0.25, and 0.28, respectively). In contrast to the lumen CSA, the vessel CSA at the three segments was overestimated by all observers when assessed by CCTA. At the segment with minimal lumen CSA, the vessel CSA obtained by CCTA showed weak correlations with those assessed by IVUS (<I>r</I> = 0.43, 0.33, 0.44, 0.37, and 0.42, respectively).

Kim, Byeong-Guk,Kim, Jun-Hwa,Kim, Myung-In,Han, Jeong Joon,Jung, Seunggon,Kook, Min-Suk,Park, Hong-Ju,Ryu, Sun-Youl,Oh, Hee-Kyun Korean Association of Maxillofacial Plastic and Re 2016 Maxillofacial Plastic Reconstructive Surgery Vol.38 No.-

Background: This study was performed to evaluate their 5-year survival rates and identify the factors affecting the prognosis of oral cancer patients who had undergone surgical treatment only. Methods: Among 130 patients who were diagnosed with malignant tumor of oral, maxillofacial, and surgical treated in the Department of Oral and Maxillofacial Surgery at Chonnam National University Hospital within a period from January 2000 to December 2010, for 11 years, 84 patients were investigated who were followed up for more than 5 years after radical surgery; oral cancer is primary and received only surgical treatment. The survival rate according to gender, age, type and site of cancer, TNM stage, cervical lymph node metastasis and its stage, recurrence or metastasis, time of recurrence and metastasis, and differentiation were investigated and analyzed. Results: Overall, 5-year survival rate in patients who received only surgical treatment was 81.2 %, and disease-specific 5-year survival rate was 83.1 %. The disease-specific 5-year survival rate based on TNM stage, metastasis of cervical lymph node, N stage, and presence of recurrence/metastasis was a significant difference (p < 0.05). The disease-specific 5-year survival rate based on sex, age, type of tumor, primary site, and differentiation was not a significant difference (p > 0.05). Conclusions: These results suggest that good survival rate can be obtained with surgical treatment only, and stage of oral cancer, cervical lymph node metastasis and stage, recurrence or metastasis, time of recurrence, and metastasis have a significant effect on survival rate in oral cancer patients.
