Objectives : A voxel based investigation of cerebral blood flow was conducted to identify functional differences during resting state between children with early-onset schizophrenia and normal controls. Methods : 19 children and adolescents with early-onset schizophrenia(8 boys and 11 girls, mean age $14.0{\pm}1.7$ years old) and 17 comparison children(13 boys and 4 girls, mean age $11.0{\pm}1.9$ years old) were examined by HMPAO-SPECT. The SPECT images were compared using statistical parametric mapping analyses, controlling for age and sex. Results : Increased cerebral blood flow in left medial and inferior frontal gyrus, right superior and middle frontal gyrus, both inferior temporal gyrus, and right cerebellar tonsil was found in children and adolescents with early-onset schizophrenia compared to control subjects. In addition, decreased cerebral blood flow in right thalamus, left posterior cingulate gyrus, right anterior cingulate gyrus and relatively wide areas from left medical frontal gyrus to superior parietal lobule were found in children and adolescents with early-onset schizophrenia compared to control subjects. Conclusion : The results of the current study provide additional evidences for brain areas involving the onset of schizophrenia in early age.

Purpose: The purpose of this study was to examine late-onset hypogonadism, erectile dysfunction, depression, and quality of life among middle-aged male workers. Methods: The subjects included 343 men aged between 40 and 64, responded to self-report questionnaires on general characteristics, late-onset hypogonadism, erectile dysfunction, depression, and quality of life. Data were collected from May 16, 2012 to October 9, 2012 and analyzed using t-test, ANOVA, $x^2$-test, hierarchical multiple regression. Result: The prevalence rate of late-onset hypogonadism was 63.8% with high points in reduction of libido, energy, physical strength and endurance, and erectile function. There were significant differences in late-onset hypogonadism according to age($x^2$=8.98, p=.048) and in erectile dysfunction according to age(F=11.03, p<.001), monthly income(F=2.84, p=.024) and smoking( t=2.96, p=.018). Significant differences were also found in depression according to educational level(F=8.12, p<.001) and in quality of life according to monthly income(F=7.21, p<.001). The factors which influenced quality of life were late-onset hypogonadism, erectile dysfunction, depression, marital status and religion. Conclusion: Symptoms of erectile dysfunction can be improved by smoking cessation education program. In order to improve the life quality of middle-aged men, nursing intervention programs that would both provide proper knowledge on climacteric syndrome and alleviate symptoms should be designed while, at the same time, other programs to evaluate, prevent and control depression are developed.

소아기 발병 정신분열병(COS)은 비록 흔하지는 않지만 성인 발병 정신분열병에 비해 보다 동질적인 집단이며 질병의 진행과정을 추적할 수 있다는 면에서 정신분열병 연구자들의 관심의 대상이 된다. COS 환자에대한 기존의 연구 결과들은 소아에서도 성인 진단기준에 의거한 구조적면담을 통해 객관적으로 타당성 있는 정신분열병 진단이 가능하다는 것이다. 또한 소아와 성인 발병 정신분열병이 동일한 임상양상과 질병 진행과정을 보이며 생물학적 여러분야(신경심리, 신경생리, 뇌 구조, 뇌 생화학, 유전 및 염색체)의 연구결과들 역시 성인 발병 정신분열병과 동일한 소견을 보인다는 것이다. 다만 차이점은 COS의 경우 치료 약물반응이 상대적으로 떨어지고, 임상경과 및 예후가 나쁘고, 발병전 발달(언어, 인지, 섬세운동)에 문제가 심각하고, 염색체 이상, 정신분열병이나 정신분열병 스펙트럼 장애의 가족력이 흔하여 유전적 부하가 높다는 것이다. 향후 COS 환자를 대상으로한 유전연구 및 뇌발달 영상 추적연구는 정신분열병의 뇌 신경발달에 관한 기초적인 지식을 확대시킬 것이다. 즉 뇌 발달을 조절하는 유전자의 기능과 발현 시기에 대한 좀 더 명확한 지식을 제공할 것이며 이를 토대로한 위험군에 대한 조기발견 및 치료방안이 강구되어야 하겠다.

Objectives: Late-onset schizophrenia (LOS, age at first onset ≥40 years) is characterized by including predominance of women, better premorbid social adjustment and lower severity of positive/negative symptoms. However, few studies have been conducted on LOS, especially in Asian countries. This study aimed to examine the clinical features of LOS in comparison with early-onset schizophrenia (EOS). Methods: By retrospectively reviewing medical records, we assessed demographic data and clinical features of 76 LOS (20 males) and 357 EOS (144 males) who admitted to the psychiatric ward of a general hospital. Results: The mean ages of onset were 47.3±5.1 (LOS) and 25.7±6.5 (EOS) years. There were significantly more women in LOS (73.7%) than EOS (59.6%). Significantly more LOS patients had a marital (88.2% vs. 25.8%) and employment history (28.9% vs. 13.1%) than EOS. Patients with LOS had fewer negative (14.3±9.0 vs. 19.9±9.3), general psychopathology score (36.9±11.1 vs. 42.3±13.9) than EOS patients. Conclusion: In line with previous studies, this study demonstrated that LOS patients have better premorbid social adjustment. Our finding also replicates previous findings that LOS patients differ from EOS in predominance of women and relative lack of negative symptoms. These results suggest that LOS may be a distinct subtype of schizophrenia.

Background: Well-validated risk prediction models help to identify individuals at high risk of diseases and suggest preventive measures. A recent systematic review reported lack of validated prediction models for low back pain (LBP). We aimed to develop prediction models to estimate the 8-year risk of developing LBP and its recurrence. Methods: A population based prospective cohort study using data from 435,968 participants in the National Health Insurance Service-National Sample Cohort enrolled from 2002 to 2010. We used Cox proportional hazards models. Results: During median follow-up period of 8.4 years, there were 143,396 (32.9%) first onset LBP cases. The prediction model of first onset consisted of age, sex, income grade, alcohol consumption, physical exercise, body mass index (BMI), total cholesterol, blood pressure, and medical history of diseases. The model of 5-year recurrence risk was comprised of age, sex, income grade, BMI, length of prescription, and medical history of diseases. The Harrell's C-statistic was 0.812 (95% confidence interval [CI], 0.804-0.820) and 0.916 (95% CI, 0.907-0.924) in validation cohorts of LBP onset and recurrence models, respectively. Age, disc degeneration, and sex conferred the highest risk points for onset, whereas age, spondylolisthesis, and disc degeneration conferred the highest risk for recurrence. Conclusions: LBP risk prediction models and simplified risk scores have been developed and validated using data from general medical practice. This study also offers an opportunity for external validation and updating of the models by incorporating other risk predictors in other settings, especially in this era of precision medicine.

Early onset scoliosis (EOS) describes the onset of scoliosis before the age of 10 years and is associated with significant health risks. Compared to adolescent idiopathic scoliosis, studies on the etiology of EOS in children are more common. EOS includes inhomogeneous groups of patients, and the etiology of EOS may be congenital, neuromuscular, syndromic, or idiopathic. The identification of the molecular etiology underlying patients with EOS has been increasing. This could provide valuable information for optimizing the management and care of these children. In this review, EOS was reviewed from a medical genomic perspective.

Background: Rotavirus is the most common cause of severe gastroenteritis in children <5 years of age. The first vaccine, RotaShield was developed, but withdrawn because of its association with increased risk of intussusception. Then, RotaTeq and Rotarix were developed. Although in pre-licensure studies, they were not associated with an increased risk of intussusceptions, in recent studies, it has been controversial. Regarding increased risk of intussusception, we studied the difference in the age of intussusception after rotavirus vaccination. Methods: A retrospective analysis was conducted on 136 patients diagnosed with intussusception at Yeungnam University Medical Center for 4 years in the pre-vaccination period (group A) and in the post vaccination period (group B). Sex, mean age and age distribution of intussusceptions were compared according to the type of rotavirus vaccine (group B-1, RotaTeq; group B-2, Rotarix). Results: The median ages of group A and group B were $18.8{\pm}19.6months$ and $15.5{\pm}10.2months$, with no significant differences (p=0.23). The median ages of group B-1 and group B-2 were $15.3{\pm}9.3months$ and $15.6{\pm}10.8months$, with no significant differences (p=0.91). And No significant difference in the distribution of onset age was observed between groups, and only 6 patients were diagnosed with intussusceptions within 1 month after vaccination. Conclusion: No difference was observed in the distribution of onset age of intussusception after rotavirus vaccination and according to the type of rotavirus vaccine. Our study has a limitation in that it was conducted in part of the Daegu area. Additional study is needed.

본 연구는 성별에 따른 음주시작연령과 BMI 간의 상관관계를 파악하여 청소년기 음주행태와 성인기의 건강과의 관계에 대해 고찰하고자 한다. 본 연구는 2019년 지역사회건강조사를 활용하여 206,987명의 연구대상자를 대상으로 이분형 로지스틱 회귀분석을 실시하였다. 연구결과, 음주시작연령이 성인기 이전인 경우 성인 남성의 BMI가 비정상일 오즈값이 통계적으로 유의미하게 높았다. 이러한 연구결과는 남성의 높은 알코올 소비량과 음주에 대한 성별에 따른 차별적인 음주문화 때문인 것으로 설명할 수 있다. 본 연구는 성인기 이전의 조기음주가 야기할 수 있는 한시적인 어려움이 아닌 장기적인 건강 부작용 측면을 다룸으로써 자발적인 문제성 음주를 예방의 필요성을 강조하였다.
