  • The genetic association test on age of onset trait aims to detect the putative gene by means of linear rank tests for a significant trend of onset distributions with genotypes. However, due to the selective sampling of recruiting subjects with ages less than a pre-specified limit, the genotype groups are subject to substantially different censored distributions and thus this is one reason for the low efficiencies in the linear rank tests. In testing the equality of two survival distributions, log-rank statistic is preferred to the Wilcoxon statistic, when censored observations are nonignorable. Therefore, for more then two groups, we propose a generalized log-rank test for trend as a genetic association test. Monte Carlo studies are conducted to investigate the performances of the test statistics examined in this paper.

  • Objectives : This study was designed to compare the demographic data, clinical characteristics, developmental delay, and psychological tests between childhood-onset and adolescent-onset schizophrenic in-patients. Methods Medical records of the 17 childhood-onset (very early onset) Schizophrenia and 16 adolescent-onset (early onset) Schizophrenia in-patients were reviewed. Sex, age, psychiatric past history, prodromal symptoms and period, subtype, co-morbid disease, developmental delay, prescribed drug and dosage, treatment response, intelligence quotient (IQ), and Rorschach test were evaluated. Results : The mean admission age of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 12.69$({\pm}2.34)$ and 15.13$({\pm}1.04)$ years. The mean onset age of childhood-onset(very early onset) group and adolescent-onset (early onset) group were 10.79$({\pm}1.95)$ and 14.46$({\pm}0.82)$ years. The mean prodromal period of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 15.94$({\pm}12.33)$ and 8.06$({\pm}6.10)$ month. The time to remission period of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 50.58$({\pm}24.67)$ and 30.06$({\pm}18.04)$ days. Longer time to remission period in childhood-osnet (very early onset) group was associated with earlier age of onset. The mean of total IQ, performance IQ, verbal IQ were at an average level. Discussion : Childhood-onset (very early onset) group and adolescent-onset (early onset) group Schizophrenia had different clinical and psychological features including prodromal period, and IQ subtests.

  • 위암의 발병률이 감소하고 있기는 하지만 전 세계적으로 여전히 연 100만 명 이상이 새롭게 위암으로 진단되고 있으며, 앞으로 향후 몇십 년 동안은 인구의 고령화로 인하여 위암에 대한 사회적 경제적 부담이 줄어들지 않을 것으로 추측된다. 최근 메타분석에서 Helicobacter pylori 제균 치료가 위암발병을 33~47% 감소시킨다고 보고하였으나, 중국에서 시행된 무작위 대조 연구에서는 제균 치료가 위암의 전구 병변 감소에 도움이 되지 않았다고 보고하고 있어 위축성 위염이나 장상피화생을 동반한 경우 제균 치료가 위암 예방에 큰 도움이 되지 않을 수 있음을 제시하고 있다. 그렇다면 위축성 위염이 있는 경우가 많은 고령 환자에서는 과연 헬리코박터 제균 치료가 도움이 될 것인가? 저자들은 빅데이터 분석을 통해 헬리코박터 제균 치료가 위암 발병에 미치는 영향을 성별과 연령에 따라 분석하였다. 2003년부터 2012년까지 'Hospital Authority'에 등록된 clarithromycin 포함 3제 요법을 받은 환자들에서의 위암 발생률과 2003년부터 2013년까지 'Hong Kong Cancer Registry'에 등록된 성별과 연령이 일치된 대조군에서의 위암기대 발생률(expected incidence)을 비교하였다. 3제 요법을 받은 73,237명의 환자들을 확인하였을 때, 평균 7.6년의 추적기간 중 200명(0.27%)에서 위암이 발생하였다. 연령에 따라 40세 미만, 40~59세, 60세 이상의 그룹으로 나누어 각각 위암발생률을 대조군과 비교한 결과 60세 이상 환자군에서만 standardized incidence ratio (SIR)가 0.82로 감소하였다. 치료 성공여부에 따라 위암 발생률을 분석하였을 때, 제균 치료에 성공한 60세 이상 군에서 SIR이 0.78로 감소하였으나 재 치료를 받은 40~59세 군에서는 SIR이 2.43으로 증가하였다. 제균 치료시점이 위암 발생률에 미치는 영향으로는 제균 치료 후 10년 미만에서의 위암 발생률에는 큰 영향이 없었으나 10년 이상 경과한 경우 60세 이상 군과 40~59세 군에서의 위암 발병률이 대조군의 위암 예측 발병률보다 낮았다.

  • Objective:The objective of this study is to examine the clinical characteristics and behavioral comorbidity of patients with Tourette’s disorder. Method:Subjects consisted of 157 patients with Tourette’ disorder diagnosed by DSM-IIIR, who were examined and diagnosed from Jan. 1988 to May 1994 at the Tourette’s Clinic of Yonsei University Medical Center. Characteristics and behavioral comorbidity of Patients were assessed by a semi-structured interview schedule. Behavioral problems like hyperactivity, obsession-compulsion, self destructiveness, enuresis, sleep problem were assessed by global clinical impression. Results:The mean age of patients was 14.49(${\pm}7.99$) years. Patients consisted of 138 males (87.9%) and 19 females(12.1%). The sex ratio was 7:1, showing a male preponderance. The number of right-handers was 133(84.7%), and the number of non-right handers was 24(15.3%). Mean age of onset was 8.85(${\pm}4.56$) years, ranging from 2-to-16 years. More than half of the patients had their age of onset at 6-10 years. Bimodal peak in age of onset was observed;the first peak was around 6 and the second peak was around 10 years. There was no sex difference in bimodal age of onset. The most common initial symptom was eye blinking. More than 55% of patients reported eye blinking as their first symptom. The second common initial symptom was head turning and the third was vocal tic. The most common symptoms that patients reported on their first visit since onset were eye blinking(82.2%), head turning or nodding(57.9%), shoulder shrugging(52.7%) and forearm movement(32.6%). Of 157 cases, 101(64.3%) patients showed downward progression of symptoms, and 25(15.9%) showed upward progression of symptoms. Nineteen fathers(12%) of patients had a past history of obsessive-compulsive disorder(OCD). Seventeen fathers(10.6%) had a history of tic disorder. SSevenmothers(4.5%) had OCD, 4 mothers (2.5%) had tic disorder. One hundred and eighteen patients(75.1%) had comorbid hyperactivity, 95 patients(60.5%) had obsession, 55 patiens(35.0%) had self destructiveness, 46 patients(29.3%) had impulsivity, and 35 patients(22.3%) had enuresis. Age of onset had a significant positive correlation with age, duration, and the global severity of obsession;and a negative correlation with the severity of hyperactivity. Hyperactivity had a significant positive correlation with impulsivity, obsession-compulsion, enuresis, and self destructiveness. Obsession-compulsion had a significant positive correlation with hyperactivity, sleep problems, and self destructiveness. Conclusion:These data suggest that clinical characteristcs and behavioral comorbidity of patients with Tourette’ disorder in this study are similar to previous research findings in Korea and other contries. The younger the age of onset was, the more severe hyperactivity was, and the less severe obsession-compulsion was. And severity of hyperactivity had a positive correlation with the severity of obsession-compulsion, impulsivity, enuresis, and self destructiveness.

  • 목적 : 대표적인 motor neuron disease(MND)이면서 가장 치명적인 신경퇴행성 질환인 ALS의 발생 양상과 한방치료효과에 대하여 연구하였다. 방법: 상지대학교 부속 한방병원에 래원한 ALS 환자들의 성별, 연령, 발병일, 발병양상, 래원 당시의 병태양상 등을 분석하였고, 이 중 3개월 이상 입원치료를 통하여 치료과정 평가가 가능하였던 18명의 환자들의 치료 전과 치료 후의 변화양상을 평가하였다. 결과 : 외국의 보고에 비하여 여성 환자가 많았고 발병 연령도 유의하게 낮았으며 상지에서 최초의 증상이 발현되는 비율이 상대적으로 높았다. Bulbar From의 비율도 높았고, 대부분의 환자가 여성인 것도 특이하였다. 환자들이 생각하는 질병의 발생원인 중 약 80%가 stress나 정신적 충격 등을 지적하여 정신적 불안상태가 유관함을 추정할 수 있었다. 한방치료가 ALS를 호전시키지는 못하였으나 진행을 억제하였고, 국소적인 주소증을 완화시키며 심리적 안정 상태를 유지하는데 도움이 된다고 평가되었다.

  • Object:The purpose of this study was to investigate that infection with group $A[{\beta}]$ hemolytic streptococcus may associate the mechanisms that cause or exacerbate the tic symptoms in some cases of Tourette's disorder Method:Fourteen cases with abrupt worsening of tics participated in this study:10 males,4 females. The subjects were divided into two groups composing of the group with increasing level of ASO titer and the group with normal level of ASO titer. The subjects were administered Yale Global Tic Severity Scale(YGTSS). Result:The global severity scores and overall TS impairment rating scores of YGTSS in the group with increasing level of ASO titer were more higher than in the group with normal level of ASO titer Conclusion:These results suggest that increasing level of ASO titer, resulting from group $A[{\beta}]$ hemolytic streptococcal infection has affected worsening the tic symptoms in Touette's disorder.

  • Objective : The correlation between age of onset and symptoms/severity of panic disorder has not yet been determined. The aim of this research is to determine the different clinical features of panic disorder according to the age of onset. Methods : Patients diagnosed with panic disorder were placed into two groups according to onset of age. The subjects were checked for 13 different panic symptoms presented in the DSM-IV. The investigation was also executed by severity, the anxiety sensitivity index, the scale for depression and anxiety. Results : The early onset group had significantly higher frequencies than the late onset group in the areas of "choking feeling" and "derealization or paresthesia". It was found that only "choking feeling" was statically significant as a risk factor of early onset panic disorder. Among the objective anxiety scale, the subscale of psychological anxiety was higher in the early onset group compared to the late onset group. Conclusion : "Choking feeling" was the only panic symptom that showed a significant difference in accordance with onset age. Earlier onset patients tend to experience a more frequent "choking feeling," which is related to respiratory symptoms. This could mean that earlier onset patients are more likely to have higher psychological anxiety.
