Authors evaluated alterations of observable metabolite ratios between the cerebral lesion and the contralateral region related to the clinical symptomatic side in levodopa-treated Parkinson's disease (PD) and investigated correlation between age in patients with PD and metabolite ratios of the lesion. Patients with levodopa-treated PD (n = 54) and age-matched normal controls (n = 15) underwent magnetic resonance spectroscopy (MRS) examinations using a stimulated echo acquisition mode (STEAM) pulse sequence that provided 2$\times$2$\times$2 cm3 volume of interest in the selected regions of substantia nigra (SN) and putamed-globus pallidus (PG). To evaluate dependence of metabolite ratios on age, we divided into two groups (i.e., younger and older age). We quantitatively measured N-acetylaspartate (NAA), creatine (Cr), choline-containing compounds (Cho), inositols (Ins), and the sum of glutamate (Glx) and GABA levels and obtained proton metabolite ratios relative to Cr using a Marquart algorithm. Compared with the contralateral region, a significant neuronal laterality of the NAA/Cr ratio in the lesion of SN related to the clinical symptomatic side was established (P = 0.01), but was not established in the lesion of PG (P = 0.24). Also, Cho/Cr ratio tended toward significance in the lesion of SN (P = 0.07) and was statistically significant in the lesion of PG(P = 0.01). Compared with that in the younger age group, NAA/Cr ratio in the older age was decreased in the lesion of SN (P = 0.02), while NAA/Cr ratio was not statistically significant in the lesion of PG ( P = 0.21). Significant metabolic alterations of NAA/Cr and Cho/Cr ratios might be closely related with functional changes of neuropathological process in SN and PG of levodopa treated PD and could be a valuable finding for evaluation of the PD. A trend of NAA/Cr reduction, being statistically significant in older patients, could be indicative of more pronounced neuronal damage in the SN of the progressive PD.

목적 : 다감각 통합은 인지과제나 운동실행을 위해 다양한 감각정보를 사용하는 데 있어서 필수적인 처리과정이다. 특히 시각 및 체감각의 통합은 운동 행동의 주요한 요소이다. 본 연구는 감각통합 과정의 시간적 경로와 뇌의 담당 위치를 파악하기 위해 신경생리학적 연구방법을 사용하여 시각과 체감각의 통합과정과 관련된 뇌의 시간적 및 공간적 특성을 조사하였다. 연구 방법 : 실험실 상황에서 시각과 촉각 자극을 독립적으로 또는 동시에 제시하고 유발전위검사(ERP: Event-Related Potentials)를 통해 통합작용 시 뇌에서 일어나는 신경세포들의 전기생리적활동을 측정하였다. 이때 시각 과 촉각을 각각 제시하여 얻은 유발전위신호들의 선형합과 두 개의 자극을 동시에 제공하였을 시 발생되는 유발전 위신호를 측정하여 비교하였다. 결과 : 시각과 촉각을 독립적으로 각각 제시하여 얻은 유발전위신호(SUM)의 합과 두 개의 자극을 동시에 제공하여 얻은 유발전위신호(SIM)는 같지 않았다. 특히나 자극의 반대측인 오른쪽 일차체감각영역(C4)에서 SIM은 SUM 보다 특정시간대에 통계적으로 유의미한 차이를 보였으며, Bilateral parietal areas(P3, Pz, P4) 뿐만 아니라 일차 시각영역(O1,O2)에서도 두 조건간 추가적인 통합관련 신경활동전기신호에 의한 통계적으로 유의미한 차이를 나타내고 있다. 결론 : 뇌 속에서 2개 이상의 감각이 통합될 경우 이와 관련된 추가적인 신경세포활동이 일어나고 있으며, 이는 다 감각을 동시에 제공할 경우 뇌의 활동을 더욱 활발하게 촉진시키고 있음을 시사한다.

Purpose: Bell's palsy is characterized by sudden onset of unilateral facial weakness. The use of corticosteroids for childhood Bell's palsy is controversial. This study aimed to identify clinical characteristics, etiology, and laboratory findings in childhood Bell's palsy, and to evaluate the efficacy of corticosteroid treatment. Methods: We conducted a retrospective analysis of children under 19 years of age treated for Bell's palsy between January 2009 and June 2017, and followed up for over 1 month. Clinical characteristics, neuroimaging data, laboratory findings, treatments, and outcomes were reviewed. Patients with Bell's palsy were divided into groups with (group 1) and without (group 2) corticosteroid treatment. Differences in onset age, sex, laterality, infection and vaccination history, degree of facial nerve palsy, and prognosis after treatment between the groups were analyzed. Results: One hundred patients were included. Mean age at presentation was $7.4{\pm}5.62years$. A total of 73 patients (73%) received corticosteroids with or without intravenous antiviral agents, and 27 (27%) received only supportive treatment. There was no significant difference in the severity, laboratory findings, or neuroimaging findings between the groups. Significant improvement was observed in 68 (93.2%) and 26 patients (96.3%) in groups 1 and 2, respectively; this rate was not significantly different between the groups (P=0.48). Conclusion: Childhood Bell's palsy showed good prognosis with or without corticosteroid treatment; there was no difference in prognosis between treated and untreated groups. Steroid therapy in childhood Bell's palsy may not significantly improve outcomes.

To evaluate the diagnostic usefulness and significance of quantitative sacroiliac joint scintigraphy in the assessment of sacroiliitis, we measured Sacroiliac Joint/Sacrum Uptake Ratio(SIS Ratio) by region of interest(ROI) method using $^{99m}Tc-methylene$ diphosphonate. The observed results were as follows: 1. Using ROI method, the SIS ratios for the control group of 65 persons were $1.05{\pm}0.08$(left) and $1.06{\pm}0.07$(right) which were narrower in range than those of slice method $(mean{\pm}S.D.)$. 2. The effects of age, gender and laterality on SIS ratio were not significant. 3. In left side, one of 6 patients with rheumatoid arthritis had SIS ratio in excess of 2 standard deviation of normal control group, and remainder had SIS ratios within normal limit. In right side, 3 patients had SIS ratios in excess of 2 standard deviation of normal control group, and remainder, within normal limit. 4. In both sacroiliac joint, 2 of 3 patients having sacroiliitis clinically with Reiter's syndrome whose pelvis A-P X-ray findings showed normal had high SIS ratios (left/right; 1.31/1.69, 1.90/1.80), but SIS ratio of one patient who had no evidence of sacroiliitis clinically was within normal limit. 5. In 6 patients with ankylosing spondylitis in both sacroiliac joints, 4 whose pelvis A-P Xray findings showed severe sclerotic change of sacroiliac joints had SIS ratio within normal limit or below that of normal control group, and SIS ratios of 2 patients whose pelvis A-P X-ray findings showed were increased. 6. 4 of 5 patients with low back pain of which cause could not be evaluated clinically and radiologically had SIS ratios in excess of that of normal control group. It would be concluded that quantitative sacroiliac joint scintigraphy is useful and sensitive screening method in the diagnosis as well as in the assessment clinical activity of sacroiliitis.

목적 : 선천성 수신증 환아에서 방광요관역류(VUR)가 어떠한 관련이 있는지 또한 요로감염 발생 여부와 어떠한 연관이 있는지 정보가 부족하다. 이에 연구자들은 VCUG를 시행 받은 선천성 수신증 환아를 대상으로, 수신증과 VUR 간의 연관성 및 요로감염 발생 여부에 대하여 분석을 하여 환자관리에 도움이 되는 정보를 마련하고자 하였다. 방법 : 연구는 2002년 1월 1일부터 2008년 12월 31일까지 아주대학교 병원에서 선천성 수신증으로 진단된 생후 1개월 이내의 환아 중, VCUG를 시행 받은 122명을 대상으로 후향적 연구를 하였다. 측정치의 통계분석은 SPSS version 16.0을 사용하여 logistic regression, T-test, chi-square test 등을 실시하였으며, P<0.05인 경우 통계학적으로 유의한 것으로 평가하였다. 결과 : 총 122명의 선천성 수신증 환자 중 남자가 많았고(73%), 주로 편측 수신증을 가진 환자가 많았으며(77%), 그 중 좌측(84.0%) 수신증 환자가 유의하게 많았다. VUR은 총 23명(18.9%)에서 발견되었다. 수신증의 심한 정도는 좌우측에 따른 차이를 보이지 않았으며, VUR의 정도도 좌우측에 따른 차이를 보이지 않았다. 수신증을 1-4단계로 나누었을 때, 각 단계별로 VUR의 발생빈도 차이는 관찰할 수 없었으나, 수신증을 경한 수신증(1-2단계)과 중한 수신증(3-4단계)으로 나누었을 때 중한 수신증에서 VUR의 발생 빈도가 유의하게 높음을 확인할 수 있었다. 또한 영아기 동안에 요로감염 발생을 살펴보면, 수신증이 심하거나 VUR이 있을 경우 그 발생빈도가 높았다. 결론 : 선천성 수신증 환아에서 수신증의 정도가 심할 경우 더욱 VUR의 빈도가 더 높았으며, VUR이 존재할 경우 영아기에 요로감염이 더 흔히 발생함을 알 수 있었다.

Objectives: Temporomandibular joint ankylosis (TMJA) is a joint pathology caused by bony and/or fibrous adhesion of the joint apparatus, resulting in partial or total loss of function. Materials and Methods: This is a retrospective study conducted between 2012 and 2016 in the northwest region of Nigeria. The data retrieved includes gender, age, etiology of ankylosis, duration of ankylosis, laterality of ankylosis, type of imaging technique, type of airway management, types of incision, surgical procedure, mouth opening, interpositional materials used, and complications. Results were presented as simple frequencies and descriptive statistics. Results: Thirty-six patients with TMJA were evaluated during the study period. There were 21 males (58.3%) and 15 females (41.7%), yielding a male:female ratio of 1.4:1. The patients' age ranged from 5 to 33 years with $mean{\pm}standard$ deviation ($13.8{\pm}6.6years$). Thirty-five cases (97.2%) were determined to be true/bony ankylosis, while only 1 case (2.8%) was false/fibrous ankylosis. Most of the TMJA cases (16 cases, 44.4%) were secondary to a fall. In our series, the most commonly utilized incision was the Bramley-Al-Kayat (15 cases, 41.7%). The mostly commonly performed procedures were condylectomies and upper ramus ostectomies (12 cases each, 33.3%), while the most commonly used interpositional material was temporalis fascia (14 cases, 38.9%). The complications that developed included 4 cases (11.1%) of severe hemorrhage, 1 case (2.8%) of facial nerve palsy, and 1 case (2.8%) of re-ankylosis. Conclusion: Plain radiographs, with their shortcomings, still have significant roles in investigating TMJA. Aggressive postoperative physiotherapy for a minimum of 6 months is paramount for successful treatment.

The survey on branchial anomalies was conducted by Korean Association of Pediatric Surgeons. A total of 173 cases were reported, which were managed by 36 members and cooperators during the three years from January 1, 1993 through December 31, 1995. The following results were obtained by retrospective analysis of the 173 cases of branchial anomalies. The presenting symptoms were cervical mass in 101 cases, pit with or without discharge in 71, cervical abscess in 47 and respiratory difficulty in 3. The average age of the patients with cervical abscess was 52 months. Seventy(79%) of 89 patients with branchial anomalies and a cystic mass had their first clinical manifestations by 1 year of age, while 40(51%) of 78 patients with only a branchial cyst had their first clinical manifestation in first year of life. Radiologic studies were carried out in 77 patients (43%). The preferred diagnostic modalities were ultrasonography(47 patients), simple neck radiogram(19) and CT scan(17). Preoperative diagnosis was correctly made in 156(91%) of 173 patients. Seventeen patients were incorrectly diagnosed as thyroglossal duct cyst in 5 patients, cystic hygroma in 4, dermoid cyst in 3, and lymphadenopathy in 3. There were no remarkable difference in sex and laterality of presentation but bilateral lesions were found in 9(5%) patients and unusual locations of the anomalies were the manubrium, left subclavicular area, median cervial area, preauricular and parotid area. There were 78(45%) patients with cyst, 52(30%) patients with sinus, 35(20%) patients with fistula and 8(5%) patient with skin tag. Embryological classification was possible in only 64(37%) patients. The 2nd branchial anomaly was present in 50(78%), the 1st branchial anomaly in 10(18%), and the 3rd or 4th branchial anomaly in 4(6%). Histopathological study of the lining epithelium(N=134) is recorded that 45% were lined with squamous epithelium, 17% with respiratory epithelium, 6% with. squamous and respiratory epithelium, 14% with inflammatory change. Lymphoid tissue was common(62%) in the wall of the lesions. Twelve(7%) of 158 patients had postoperative complications including wound complication, recurrence and facial nerve palsy.

Objectives Alteration of epigenetic effects of testosterone during early development was suggested as an ancillary mechanism for the genesis of schizophrenia. EEG coherence was thought to be a marker for cerebral laterality of which important determinant was testosterone during early development. We studied sex-related differences of EEG coherences between patients with schizophrenia and controls to examine the sex effects in the genesis of schizophrenia. Methods EEG was recorded in 35 patients with schizophrenia and 46 healthy controls in the eyes closed resting state. Pair-wise EEG coherences were calculated over delta, theta, alpha, beta and gamma frequency bands. To examine the differences of EEG coherence according to sex in each group, ANCOVA was performed using Statistical Analysis system (SAS, Ver 9.3) and R (Ver 2.15.2). Results Healthy control males showed more increased right intrahemispheric coherences than healthy control females in delta, theta, alpha and beta frequency bands. In patients with schizophrenia, this male dominant pattern in right intrahemispheric coherences was attenuated especially in alpha and beta bands. Healthy control females showed more increased interhemispheric coherences than healthy control males in delta, theta, beta and gamma frequency bands. In patients with schizophrenia, these female dominant patterns in interhemispheric coherences were attenuated especially in delta, theta, and beta bands, which were commonly observed in frontal to central areas. Conclusion Sex differences in resting EEG coherences were attenuated in schizophrenia patients. These results imply that sex-related aberrant cerebral lateralization might exist in patients with schizophrenia, which are partly due to sex hormones via epigenetic mechanisms.
