Infection with human papillomavirus (HPV) could affect genesis of both cervical and esophageal cancers. The type-specific distribution of HPV in cervical cytology abnormalities of women has remained unclear in Shantou, an esophageal cancer high-incidence area of China. Data from 22,617 women who were subjected to cervical HPV DNA testing with simultaneous cervical cytological examination during 2009-2013 were therefore here retrospectively evaluated in a hospital-based study. Overall, 16.2% (3,584/22,114)of women with normal cytology were HR-HPV positive, with HPV-52 (4.07%) as the most common type followed by -16 (3.63%), and -58 (2.46%). Prevalence of HR-HPV was 50.3% (253/503) in women with cervical cytological abnormalities, of which in ASC-H 71.4%, ASC-US 39.1%, HSIL 80.3% and LSIL 73.7%. HPV-58 (14.12%) was the most common type for all cervical cytological abnormalities, followed by HPV-16 (13.72%), and -52 (12.72%), while the more common HPV-16 type in ASC-H (42.9%) and HSIL (36.1%), HPV-52 and -58 were the most common types for ASC-US (10.3%) and LSIL (25%), respectively. Multiple HPV co-infections were identified in 33.2% (84/253) cytology abnormalities with positive HR-HPV, and the highest prevalence of HPV-58/16 combination in HSIL (28.6%, 6/21) was observed. Our data indicated a relative high prevalence of HPV-58 and -52 in women with cervical cytological abnormalities, which should be considered in the development of next-generation vaccines for Shantou.

Objective: The purpose of this study is to determine the prevalence of sinus disease and abnormalities in patients scheduled for dental implant in maxillary posterior area using cone beam CT. Patients and Method: One hundred five maxillary sinuses in eighty-seven patients who underwent cone beam CT for dental implant in maxillary posterior area were included. Any patients who had previous history of sinus operations were not included. The sinus abnormalities were classified as follows ; normal (membrane thickness <2 mm), mucosal thickening (membrane thickness ${\geq}$ 2 mm and < 6 mm), partial opacification (membrane thickness > 6 mm but not full), full opacification and mucous retention cyst. The relationship between the remaining bone height, sinus symptoms and maxillary sinus abnormality was statistically surveyed. Results: Of 105 maxillary sinuses in 87 patients, 80 (76%) maxillary sinuses showed abnormalities ; 4 of 4 symptomatic patients and 76 of 101 asymptomatic patients. Mucosal thickening was the most common sinus abnormality. Only 3 (4%) of 80 maxillary sinus abnormalities were caused by the odontogenic origin. The prevalence of maxillary sinus abnormalities was higher in the symptomatic group than asymptomatic one (p<0.05). Conclusion: Maxillary sinus abnormalities were very common in the patients who were planning implantation in maxillary posterior areas. This result supports that thorough evaluation for maxillary sinus is recommended when implant treatment is planned for those areas.

Background: Lung cancer is one of the most common types of cancer causing high morbidity and mortality worldwide. An increasing incidence of lung cancer has been observed in India. Objectives:To evaluate the clinicpathological profile and haematological abnormalities associated with lung cancer in Bangalore, India. Materials and Methods: This prospective study was carried out over a period of 2 years. A total of 96 newly diagnosed and histopathologically confirmed cases of lung cancer were included in the study. Results: Our lung cancer cases had a male to female ratio of 3:1. Distribution of age varied from 40 to 90 years, with a major contribution in the age group between 61 and 80 years (55.2%). Smoking was the commonest risk factor found in 69.7% of patients. The most frequent symptom was cough (86.4%) followed by loss of weight and appetite (65.6%) and dyspnea (64.5%). The most common radiological presentation was a mass lesion (55%). The most common histopathological type was squamous cell carcinoma (47.9%), followed by adenocarcinoma (28.1%) and small cell carcinoma (12.5%). Distant metastasis at presentation was seen in 53.1% patients. Among the haematological abnormalities, anaemia was seen in 61.4% of patients, leucocytosis in 36.4%, thrombocytosis in 14.5% and eosinophilia in 19.7% of patients. Haematological abnormalities were more commonly seen in non small cell lung cancer. Conclusions: Squamous cell carcinoma was found to be the most common histopathological type and smoking still remains the major risk factor for lung cancer. Haematological abnormalities are frequently observed in lung cancer patients, anaemia being the commonest of all.

Objectives : The aim of this study was to estimate the prevalences of electroencephalographic (EEG) abnormalities and epilepsy in children and adolescents with autism spectrum disorder (ASD). In addition, we intended to identify demographic and clinical correlates of epilepsy in ASD. Methods : A total of 140 children and adolescents (age $7.3{\pm}4.8yrs$, 106 boys) with ASD underwent EEG from January 2010 to December 2013 at Asan Medical Center. Medical records were reviewed for demographic information, clinical characteristics, psychiatric diagnoses and comorbidities, EEG findings and neurological diagnoses. Results : The prevalences of EEG abnormalities and epilepsy in children and adolescents with ASD was 62.1% and 38.6%, respectively. In subjects with seizure-like movements, EEG abnormalities and epilepsy were more frequent than those without seizure-like movements (EEG abnormalities : 92.5% vs. 43.7%, p<.001 ; epilepsy : 90.6% vs. 5.7%, p<.001). ASD subjects who had epilepsy were older (p=.001), had lower full scale intelligence quotient (p<.001) and took more antipsychotics (p=.006) than those who did not. Conclusion : The prevalences of EEG abnormalities and epilepsy in our sample were similar to those from Western countries. Our results suggested a possible association of older age, lower intelligence quotient, and antipsychotics use with epilepsy in ASD. Conduct of further prospective study in a larger sample is needed.

Purpose: A limited number of studies have examined the link between F-wave abnormalities and clinical presentation in pediatric Guillain-$Barr{\acute{e}}$ syndrome (GBS). Therefore, this study examined the importance of F-wave abnormalities as a prognostic factor in pediatric GBS patients. Methods: The records and electrodiagnostic studies (EDS) of 70 GBS patients were retrospectively evaluated, and divided into 2 groups according to the results of EDS. Group A (n=33) presented with F-wave abnormalities, and group B (n=26) exhibited normal findings. We compared laboratory reports, clinical features, response to treatment, and prognosis between the 2 groups. Results: Motor weakness was the most frequently observed symptom for either group. Clinically, the incidence of fever and upper respiratory symptoms differed between the 2 groups, while the prevalence of abnormal deep tendon reflex (DTR) was significantly higher in group A than B (P<0.05). Patients diagnosed with GBS had received intravenous immunoglobulin treatment: 94% in group A and 58% in group B. Furthermore, significantly greater numbers of patients in group A showed H-reflex abnormalities and poor prognosis compared with group B (P<0.05). Conclusion: This study demonstrated that F-waves are a clinically important prognostic factor in GBS. F-wave abnormalities were associated with abnormal DTR and poor prognosis in patients. Limited studies have examined the link between F-wave abnormalities and clinical results; therefore, further randomized controlled studies are needed to confirm the clinical characteristics and efficacy of treatments.

Objectives: This study was performed to assess the association between physical activity and the clustering of metabolic abnormalities among Korean children. The effect of substituting moderate to vigorous physical activity for the time spent in inactivity was examined as well. Methods: The study subjects were comprised of 692 (354 boys, 338 girls) 4th grade elementary school students. We used a modified form of the physical activity questionnaire that was developed in the Five-City Project. The subjects with clustering of metabolic abnormalities were defined as having two or more of the following five characteristics: waist circumference ${\geq}90\;%$, systolic or diastolic blood pressure ${\geq}90\;%$, fasting glucose ${\geq}110\;mg/dl$, triglycerides ${\geq}110\;mg/dl$ and HDL cholesterol ${\geq}40\;mg/dl$. We calculated the odds ratios to assess the effect of substituting moderate to vigorous physical activity for time spent in inactivity. Results: The risk of clustered metabolic abnormalities was inversely correlated with the increased time spent on moderate to vigorous physical activity, but the correlation was not significant. The odds ratio for clustering of metabolic abnormalities that represented the effect of substituting moderate to vigorous physical activity for 30minutes of sedentary activity was 0.87(95% Cl=0.76-1.01). Conclusions: These findings suggest that substituting moderate to vigorous physical activity for sedentary activity could decrease the risk of clustered metabolic abnormalities.

목 적 : 성염색체이상증후군은 사춘기 이후 이차 성징의 결여로 그 증상이 뚜렷해지므로 사춘기 이전의 진단은 쉽지 않다. 본 연구는 성염색체이상증후군의 빈도, 진단시 연령, 그리고 임상적 특징을 조사하여 그 의의를 알아보고자 한다. 방 법 : 1981년 2월부터 2001년 8월까지 20년 동안 경북대학교병원 소아과 염색체검사실에 의뢰된 염색체검사 중 성염색체 이상증후군으로 진단된 115례 환자의 임상적 특징, 진단시 연령 그리고 핵형 분석을 후향적인 방법으로 조사하였다. 결 과 : 성염색체이상증후군의 종류와 빈도는 Klinefelter 증후군은 52%, Turner 증후군은 42%, XXX 증후군은 3%, 혼합 성선이형성은 3%였다. Klinefelter 증후군은 47,XXY가 97%, mosaicism이 3%였고, Turner 증후군은 45,X가 67%, mosaicism이 23%, X 염색체의 구조적 이상은 10%였다. XXX 증후군은 47,XXX가 67%, mosaicism은 33%였고, 혼합 성선이형성은 모두 45,X/46,XY였다. 성염색체이상증후군의 81%가 사춘기 이후에 진단되었다. 신생아기에 Klinefelter 증후군과 Turner 증후군으로 진단받은 경우는 표현형이 정상이거나 경한 선천성기형만을 보였다. Turner 증후군과 Klinefelter 증후군의 mosaicism이나 구조적 이상군에서 전형적인 45,X나 47,XXY보다 신체상 증상 발현이 경미할 것으로 생각되었으나 본 연구에서는 통계학적으로 유의한 차이는 보이지 않았다. 결 론 : 성염색체이상증후군은 사춘기 이전에는 그 증상이 뚜렷하지 않으므로 환아에 대한 주의 깊은 관찰과 관심으로 조기에 진단하여 정상적인 정신성적발달과 성장발육 및 성생활을 유지하도록 부모와 환아의 질환에 대한 인지도를 높여야 할 것으로 사료된다. 특히 핵형 분석시 Turner 증후군은 X염색체의 다양한 구조 이상 또는 mosaicism의 빈도가 높기 때문에 핵형 분석시 이를 염두에 두어야 한다.

Purpose: Eating disorders often result in somatic complications, including cardiac abnormalities. Cardiac abnormalities may involve any part of the heart, including the cardiac conduction system, and can lead to sudden cardiac death. The current study aimed to evaluate the incidence of cardiac complications in pediatric patients with eating disorders and their associated factors. Methods: We retrospectively analyzed patients aged 10-18 years who were diagnosed with DSM-V (Diagnostic and Statistical Manual of Mental Disorder-V) eating disorders and underwent electrocardiography (ECG) and/or echocardiography between January 2015 and May 2020. Results: In total, 127 patients were included, of whom 113 (89.0%) were female. The median body mass index (BMI) was 15.05±3.69 kg/m². Overall, 74 patients (58.3%) had ECG abnormalities, with sinus bradycardia being the most common abnormality (91.9%). Patients with ECG abnormalities had significantly lower BMI (14.35±2.78 kg/m² vs. 16.06± 4.55 kg/m², p<0.001) than patients without ECG abnormalities, as well as lower phosphorus and higher cholesterol levels. Among the 46 patients who underwent echocardiographic evaluation, 23 (50.0%) had echocardiographic abnormalities, with pericardial effusion being the most common (60.9%). The median left ventricular mass (LVM) and ejection fraction were 67.97±21.25 g and 66.91±28.76%, respectively. LVM and BMI showed a positive correlation (r=0.604, p<0.001). After weight gain, the amount of pericardial effusion was reduced in 3 patients, and 30 patients presented with normal ECG findings. Conclusion: Cardiac abnormalities are relatively frequent in patients with eating disorders. Physicians should focus on this somatic complication and careful monitoring is required.
