In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Objectives : Euthymic patients with bipolar disorder have been reported to show deficits in sustained attention. This study aimed to compare the attention capacities of euthymic bipolar patients with those of control subjects using the sustained att-ention to response task (SART) and to examine the differences in the performance of SART related to the type of the stimulus. Methods : The four SART tasks were performed to measure attention capacities in 42 euthymic patients with bipolar dis-order and 28 control subjects. Happy, neutral, fearful faces and digit '3' were used as target stimuli in happy, neutral, fear and digit task conditions, respectively. The seventy of mood symptoms was assessed with 17-item Hamilton Rating Scale for De-pressive symptoms and Young Mania Rating Scale for manic symptoms. The efficiency estimate which reflects both the res-ponse accuracy and speed was used as the main outcome variable. Results : Bipolar patients showed significantly lower correct response rate than control group in all task conditions. Effi-ciency estimates of the bipolar patient group were significantly lower than those of the control group in the SART using facial stimuli, but not in the digit task condition. There was no significant difference in task performances related to the emotional categories of facial stimuli. Conclusion : Bipolar patients showed deficits in sustained attention even in the euthymic state. The attention deficits shownin the euthymic bipolar patients may be prominent in a more complex task condition with stimuli such as facial stimuli.

목적 : 정량적관상동맥조영술이 최근 널리 보급되고 있지만 국내외를 막론하고 이의 정확도 및 재현도에 관한 연구가 불충분하여 본 연구를 하였다. 대상 및 방법 : 110명의 환자에서 미국 General Electric사의 Advantx L/C/LP 디지탈혈관찰영기와 미국 USCI사의 좌관상동맥용 Judkins형의 Pro-Flo XT^(TM) 6F 도자를 이용하여 좌관상동맥조영술을 같은 각도에서 3회 실시하고 도자의 외경을 일본 Mitutoyo사의 정밀도 0.01㎜의 micrometer로 측정한 후 측정된 도자의 실제 직경과 정량적관상동맥조영술로 측정된 관상동맥의 직경을 비교하였다. 결 과 : USCI® Pro-Flo XT^(TM) 6F 좌관상동맥용 도자의 실제 외경은 1.91±0.03㎜이었고 정량적관상동맥조영술로 측정 한 도자의 외경은 1.94±0.11㎜이었다. 도자를 5.7F로 calibration했을 매 도자의 외경은 1.87±0.12㎜이었다. 세번 다 다른 화상에서 측정한 경우 근위부관상동맥 직경의 차이는 0.02±0.12㎜이었고 같은 화상에서 3회 측정하였던 경우에는 0.11±0.01㎜이었다. 결론 : 정량적관상동맥조영술의 정확도 및 재현도는 사용에 적합한 정도이나 적지 않은 문제점에 대한 보완이 필요하다고 생각된다. During quantitaive coronary angiography(QCA), contrast filled catheter is usually used as a scaling device. However the real diamerer of catheter is almost always smaller than the listed diameter. We measured the real diameter of catheters with precision micrometer(Mitutoyo® Japan). After caliberating the catheter as listed French size and diameter, we did QCA at the same tube position of the diameters of catheter and proximal left coronary artery. All measurements were done 3 times consecutively. The mean real diameter of USCI® Pro-Flo XT^(TM) 6 F left Judkin catheter was 1.91±0.03 ㎜. The mean QCA diamter of the same catheter was 1.94±0.11 ㎜. When we calibrated catheter as 1.91 ㎜. the mean QCA diameter was 1.87±0.12 ㎜. The mean differences of the diameters of the proximal left coronary artery were 0.20±0.12 ㎜ when the measurements were done in three different frames. When the measurements were done in the same frmae, the mean difference decreased to 0.11±0.01 ㎜. We conclude that the precision and reproducibility of QCA are within reasonable range, but more refimement is needed.

황진용,최지용,손상균,조용근,채성철,전재은,박의현 慶北大學校 醫科大學 1996 慶北醫大誌 Vol.37 No.4

목적 : 순환기내과 영역은 많은 과로부터 자문의뢰를 받는 영역으로 알려져 있다. 특히 최근 우리나라의 순환기질환의 유형이 변화되고 입원환자가 고령화되면서 동반된 심질환의 유병율도 증가하고있다. 이에 저자들은 타과로 입원하여 순환기내과로 자문의뢰되는 환자의 임상상과 3차병원인 경북대학교병원에서의 순환기내과자문의 유용성 등을 평가하여 향후 순환기질병에 대한 협의진료에 도움을 주고자 본 연구를 시행하였다. 방법 : 1995년 3월부터 순환기내과로 공식자문의뢰된 첫 100명을 대상으로 전향적으로 연령, 의뢰이유, 최종진단명, 수술과의 관련성 여부, 순환기내과의 최종조치, 타과의 순응도 등을 조사하였다. 결과 : 1) 자문을 의뢰한 환자는 평균 58±16(15-89, 중앙치 61)세였고 60세이상의 환자가 57%로 고령의 환자가 많았다. 2) 내과계열 25%, 외과계열 75%로 외과계열의 자문이 많았고 일반외과가 26%로 가장 많았고 내과의 다른 분과가 12%, 신경외과 12%, 정형외과 11%, 흉부외과 11%, 신경과 11% 등의 순이었다. 외과계열중 수술을 시행한 경우는 58례로 이중 응급수술이 13례였다. 술전 위험도 평가를 위한 자문이 38례에서 있었는데 순환기적인 문제로 수술을 받지 못한 경우는 2례(1례는 허혈성 심질환, 1례는 심낭질환)이었다. 이때 응급수술을 제외한 입원일과 술전 자문일파의 간격은 평균 3±7일(입원일-42일)이고 술전 자문일과 수술일과의 간격은 평균 6±4일(1-16일)이었다. 3) 타과의 의뢰이유는 심전도 이상이 36례, 높게 측정된 혈압이 20례, 순환기질환의 과거력 17례, 환자의 증상 때문인 경우가 10례였고 심전도의 이상중에는 부정맥이 18례, 이상 Q파 6례, ST절 이상이 5례, 각차단이 3례의 순이었다. 순환기과거력 중에는 허혈성 심질환이 6례, 현재 혈압은 정상이나 고혈압의 과거력이 있는 경우가 4례 순이었고 환자의 증상은 흉통 6례, 호흡곤란이 3례, 기절이 1례였다. 4) 자문후 최종진단이 가능했던 91례를 진단별(총 97 진단명)로 나누어 보면 고혈압이 28례, 부정맥이 16례, 허혈성 심질환이 14례, 판막질환이 11례, 순환기질환이 아닌경우가 19래였다. 이들중 추적진료가 필요하다고 응답한 경우가 57례였으나 순환기내과 외래에 1번이상 추적진료한 경우는 32례(56%)로 환자의 순응도는 낮았다. 결론 : 순환기내과의 자문의뢰는 고령자에게 많았고 수술과 관련된 경우가 많았으며 심전도의 이상이 의뢰이유로 가장 많았으며 진단별로는 고혈압과 부정맥이 가장 많았다. 그리고 순환기적인문제로 수술을 받지 못한 경우는 드물었고 자문후 지속적인 추적진료를 위해 환자의 교육이 필요하겠다. Objective : Clinical characteristics of the patients with cardiovascular diseases in the general hospital have been changed and prevalance of co-existing cardiovascular disease in the patients who were admitted for non-cardiac diseases has been increased remarkably as the proportion of elderly patients increased rapidly in Korea. We evaluated clinical features of the patients consulted for cardiological evaluation and effectiveness of the consultation in the setting of tertiary general hospital, Kyungpook University Hospital. Method : One hundred patients were studied between January 1995 and January 1996. They were evaluated for the reason of consultation, final diagnosis, final recommendation from cardiologists and its impact on the management of the patients, and compliance of the consulting departments. Results : 1) The ages ranged between 15 and 89 (mean 58±16, median 61) years, 57 patients were male and 43 female. Fifty seven patients were older than 60 years. 2) Consultations from surgical parts were 75 patients. Consultation from general surgery was most frequent (26%), followed by other divisions of internal medicine (12%), neurosurgery (12%) and orthopedic surgery (11%), chest surgery (11%), neurology (11%), obstetrics and gynecology (8%), urology (4%), ophthalmology (2%), dermatology (2%), ENT (1%). Among 75 patients from surgical parts, operation was done on 58 patients, including 13 emergency cases. Preoperative cardiac risk evaluation was the reason of consultation in thirty eight patients, of which operation could not be done in only 2 patients (one had severe ischemic heart disease, the other large pericardial disease). Interval between consultation day and operation day was 6±4 days (1-6 days). 3) Reasons for cardiac consultation were electrocardiographic (ECG) abnormalities in 36 patients, high blood pressure in 20 patients, previous cardiovascular diseases in 17 patients, symptoms of the patients in 10 patients. Among EGG abnormalities, arrhythmias was the reason in 18 patients, abnormal Q waves in 6 patients, ST-T segment abnormalities in 5 patients, bundle branch block in 3 patients. Among previous cardiovascular disease, presence of ischemic heart disease was the reason in 6 patients, previous hypertension in 4 patients. Chest pain was the reason of the consultation in 6 patients, dyspnea in 3 patients, syncope in 1 patient. 4) Definite diagnoses could be made in 91 patients with 96 diagnoses which were hypertension and its complications in 28, arrhythmia with underlying disease in 16, ischemic heart disease in 14. valvular heart disease in 11, non-cardiovascular disease in 19. Cardiological follow up was recommended in 57 patients. However, 25 patients (44%) were lost to follow-up. Conclusion : Cardiological consultation was frequent in the elderly patients. Most frequent reason for consultation was EGG abnormalities. Hypertension or arrhythmia was most common final diagnosis. Inoperability due to cardiovascular problems were rare.

주의력결핍과잉행동장애와 Alpha-1C-Adrenergic 수용체 유전자와의 연관성에 대한 연구

조수철,김재원,김붕년,황준원,박미라,김순애,조대연,유희정,정운선,손정우,박태원 大韓神經精神醫學會 2008 신경정신의학 Vol.47 No.1

Objectives : Neurobiological and pharmacological research has suggested that the dysregulation of the central noradrenergic systems might be involved in the pathophysiology of ADHD. The aim of this study was to examine the association of the alpha-1C-adrenergic receptor gene (ADRA1C) with ADHD in Korean subjects. Methods : In a case-control study, we assessed 186 DSM-IV ADHD probands and 150 normal controls. One hundred and eight trios were studied in a family-based association analysis. Psychiatric diagnoses were derived through structured diagnostic interviews. For the clinical evaluation of the ADHD subjects, the Child Behavior Checklist (CBCL), the ADHD Rating Scale-IV (ARS) and the Junior Temperament and Character Inventory (JTCI) were administered. A computerized continuous performance test (CPT) was used to measure the inattention and impulsivity of the ADHD children. Results : There were no significant differences in the genotype or allele frequencies of the ADRA1C PstI polymorphism between the ADHD and control group (p>0.05). The transmission disequilibrium test (TDT) analysis observed no evidence for biased transmission of any of the alleles of the PstI polymorphism. There were no significant differences in the CPT or JTCI profiles between those ADHD subjects with the CC genotype and those with the other (CT+TT) genotypes at the PstI polymorphism. Conclusion : The results of this study do not support the ADRA1C as a major genetic susceptibility factor in ADHD.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.
