Metachromatic leukodystrophy (MLD) is a progressive and degenerative neurological disease caused by a deficiency of the catabolic enzyme arylsulfatase A. Deficiency of arylsulfatase A results in accumulation of sulfatide in the white matter of the peripheral and central nervous system and it occurs demyelination as a result. The patient gradually goes through mental and motor failure. General symptoms of MLD include gait disturbance, mental deterioration, muscle rigidity and impaired swallowing. Inheritance of the disease is autosomal recessive. We report a dental caries treatment of a 3-year old boy with MLD. The patient underwent hematopoietic stem cell transplantation (HSCT) to slow the progression of the disease. He was suffered from difficulties of mastication and swallowing from the degenerative neurological symptom. He was ingesting food by both oral feeding and tubal feeding after he took percutaneous endoscopic gastrostomy (PEG). The cause of multiple caries was mainly presumed as patient's prolonged time of meal. The treatment was performed under general anesthesia considering patient's incompliance. Severely affected lower primary molars were treated with pulp treatment and restored with stainless steel crown. Others were restored with composite resin. There were no postoperative complications. MLD is life threatening progressive disease and also has an impact on unfavorable condition for oral health. Routine home oral care and periodic professional dental care should be emphasized to the caregiver of patient considering the susceptibility of dental caries. Not only the medical care, but periodic dental office visit would benefit the quality of life of the patient.

A 42 year old male was admitted for a bony mass on the posterior arc of the left $6^{th}$ rib, which was detected in a multiphasic health screening test. According to the chest computed tomography scan and bone scan, osteochondroma was suspected. He underwent VATS rib resection. There was no vessel or nerve injury. The patient was discharged without any complication on the $4^{th}$ post operative day. The pathological diagnosis was benign fibrous histiocytoma. Generally, posterolateral thoracotomy is needed for rib resection, but we found that there was no difficulty in doing this kind of surgery under a thoracoscopic approach, which has the advantage of better cosmesis.

This study intends to provide basic data to determine the effect of walking days on quality of life and oral health-related behaviors. Data from the 2019 National Health and Nutrition Examination Survey were used, and complex sample linear regression analysis and logistic regression analysis were performed to determine the effect of walking days on health-related quality of life (EQ-5D) and oral health-related behaviors. As a result, controlling for demographic characteristics, and increasing the number of walking, the health-related quality of life decreased by .284 times (p<.05) and improved by 1.485 times for oral examination, .082 times for dental caries treatment, and .009 times for nerve treatment. a fold decrease (p<.05). Therefore, it can be used as basic data on the relationship between adult walking and oral health-related behaviors and quality of life, and it is considered valuable in that it suggests the relationship between walking and oral health as well as general health.

Background: Mediastinal masses are not uncommon, and an overall incidence of one case per 100,000 population per year in individuals of all ages and with no difference in sex incidence may be a reasonable estimation. At least half of all mediastinal masses are asymptomatic and this proportion has increased in recent decades with wider use of screening chest roentgenography. Symptoms in patients with mediastinal mass lesions are usually due to compression or invasion of nearby intrathoracic structures. Most mediastinal mass lesions have characteristic predilectional locations. The basic focus of diagnostic evaluation is an orderly preparation for obtaining a tissue diagnosis but even lesions discovered to be benign must generally be removed. Seldom is this status known for certain preoperatively. In additaion, benign tumors may continue to enlarge, thus compromising vital organs; they may rupture, hemorrhage, become infected or have the possibility of various malignant degeneration. Therefore, all mediastinal masses must be surgically removed whether they are malignant or benign. Methods: We reviewed the medical records of 344 cases previously confirmed as mediastinal tumors or cysts from January, 1960 to August, 1992 and investigated the clinical findings. Results: Neurogenic tumors were the most common(24.7%) and thymomas were distinctively increased recently. Overall ratio between males and females was 1.1:1 and age distribution was relatively even among all age groups. Predilectional sites were posterior for neurogenic tumors, and anterior for teratodermoid tumors, thymomas and lymphomas. Dyspnea was the most common symptom in the patients of the mediastinal tumors and asymptomatic patients were 19.5%, Benign mediastinal mass lesions were 66.0% and malignant, 34.0%, Complete or partial resection was done in 42.4%. Conclusion: We could find the increasing incidence and the tendency of aggressive resection as possible in the mediastinal tumors. We expect the discovery of more mediastinal tumors with wider use of regular check-up and development of diagnostic methods.

Mucopolysaccharidosis (MPS) is an inherited disease entity associated with lysosomal enzyme deficiencies. MPS type 2, also known as Hunter syndrome, has a characteristic morphology primarily involving x-l inked recessive defects and iduronate-2-sulfatase gene mutation. The purpose of this case report is to provide important clues to help pediatricians identify Hunter syndrome patients earlier (i.e., before the disease progresses). A 30-month-old boy showed developmental delay and decreased speech ability. Physical examinations revealed a flat nose and extensive Mongolian spots. Brain magnetic resonance images (MRIs) showed bilateral multiple patchy T2 hyperintense lesions in the periventricular and deep white matter, several cyst-like lesions in the body of the corpus callosum, and diffuse brain atrophy, which were in keeping with the diagnosis. Based on these findings, the patient was suspected of having MPS. In the laboratory findings, although the genetic analysis of IDS (Iduronate-2-sulfatase) did not show any pathogenic variant, the enzymatic activity of IDS was not detected. We could confirm the diagnosis of MPS, because other sulfatases, such as ${\alpha}$-L-iduronidase, were detected in the normal range. Early enzymatic replacement therapy is essential and has a relatively good prognosis. Therefore, early diagnosis should be made before organ damage becomes irreversible, and brain MRIs can provide additional diagnostic clues to help distinguish the disorder.

The LAP (lipid accumulation product) index is an indicator of excessive fat accumulation in combination with the fasting triglyceride concentration and waist circumference. This study examined the relationship between the LAP index and ALT (alanine aminotransferase) level and the effect of the LAP index on the ALT level. Cross-sectional studies were conducted on healthy adult males without a history of liver disease. From January 2015 to June 2017, 13,854 adults between 20 and 70 years of age, who underwent health screening at a general hospital in Gyeonggi-do, were enrolled in this study. The LAP index was calculated as [waist circumference (cm)-65]${\times}$[triglyceride (mmol/L)] for males. Serum ALT abnormalities were set at 40 IU/L or more in males. All subjects underwent measurements of the anthropometric indicators and physiological examinations. A significant increase in ALT with increasing LAP quintiles was observed (p<0.001). The LAP index correlated with ALT (r=0.238, p<0.001). Insulin (r=0.449, p<0.001) and HDL-cholesterol (r=-0.369, p<0.001) were strongly correlated with LAP. In addition, the LAP index is a factor affecting the ALT level (p<0.001). As the LAP index increased, the risk of an elevated ALT was higher (p<0.001). In conclusion, the LAP index was a predictor of an ALT elevation in Korean men.

A survey was conducted to study perception and attitudes of examinees of health screening center towards items, cost and procedures of health examination and degree of satisfaction with health examination, from March 2 to May 31, 1995. The study population was 468 examinees received health examination at Health Screening & Diagnosis Center of Yeungnam University Hospital. A questionnaire method was used to collect data. The followings are summaries of findings : Examinees were predominantly male(77.4%); had college education(68.6%), and held white-collar workers(57.8%). Statistical significance of association between frequency of periodic health examination and other variables were tested by chi-square test. Examinees who have higher degree of concern regarding health and those who practice more exercise for health maintenance received health examination more frequently. The majority expressed that health examination is very beneficial and effective in terms of prevention and early detection of diseases. Also the majority revealed that they are satisfied with health examination. The majority expressed that procedures and time spent for health examination are adequate; interval of health examination is one year; and additional examination items are cerebral examination, neurological examination and gastrofibercope. The majority revealed that they want more information about chronic degenerative diseases and health maintenance and promotion. In conclusion, the study revealed that examinees seemed to have more positive perceptions and attitudes towards health examination.

Purpose: Gastric cancer is prevalent in Korea, therefore the purpose of this study was to determine the clinicopathologic characteristics, 5-year survival rate, and prognostic factors for gastric patients who underwent gastrectomy by a single surgeon. Materials and Methods: A total of 1,435 patients diagnosed with gastric cancer who underwent gastrectomy in the Department of Korean Gastric Cancer Center at Seoul Paik Hospital between September 1998 and August 2003, and the gender, age, location and size of the tumor, visual and histologic analysis, depth of invasion, lymph node metastasis, invasion (perineural, venous, and lymphatic), and surgical method were examined retrospectively. Results: The ratio between males and females was 2.29 : 1, and the average age was 56.7 years. Based on the UICC TNM classification, the patients were distributed as follows: IA 35.4%, IB 14.1%, II 12.6%, IIIA 12.3%, IIIB 8.3% and IV 17.3%. The 5-year survival rate was 69.6%. The results of univariate analysis showed that there were significant differences in the survival rate by age, location and size of tumor, Borrmann type, level of differentiation, Lauren's classification, depth of invasion, metastasis in lymph nodes, UICC TNM stage, invasion (perineural, venous, and lymphatic), and surgical method. Based on multivariate analysis, only the depth of invasion and lymph node metastasis were independent prognostic factors. Conclusion: Although various clinicopathologic characteristics affect the prognostic factors of the patients with gastric cancer, the results of this study showed that the stage of disease, such as depth of invasion and metastasis in lymph nodes, are the most critical factors. There is a need to establish the diagnosis of gastric cancer early and to study and develop various treatment methods based on the diagnostic factors in order to improve the survival of patients with gastric cancer.

An inverse correlation between obesity and arterial stiffness has been reported, but there are no consistent results in elderly subjects. This study examined the relationship between the arterial stiffness measured by the CAVI (cardio-ankle vascular index) and BMI (body mass index) in healthy elderly people. This study included 629 healthy elderly people aged 65 and over who underwent health examinations at a general hospital in Gyeonggi from July 2018 to June 2019. Metabolic syndrome was diagnosed using the criteria of the Adult Treatment Panel (ATP) III of the US National Cholesterol Education Program (NCEP). Among the criteria of NCEP-ATP III, the waist circumference and obesity criteria were based on the WHO criteria. All subjects underwent a biochemical blood test and an assessment of the CAVI. In both men and women, the CAVI was lower in the obese group than in the normal weight group. Gender (P=0.047), age (P<0.001), BMI (P<0.001), and waist circumference (P=0.008) were factors affecting the CAVI. Gender, high blood pressure, and hyperglycemia were independent positive predictors of the CAVI levels, while obesity was a negative predictor. Therefore, the CAVI and BMI showed an inverse correlation. In conclusion, there was an inverse correlation between the CAVI and BMI in the elderly, and obesity was a negative predictor of the CAVI.

The purpose of the present study was to develop a community-based intensive health care program for the community dwelling elderly to strength their functional status and to verify the effect on their geriatric syndrome. A one-group pretest-posttest design was used for the study. A total of 69 frail elderly, who lived in the area within 20 minutes by car, were committed themselves to the day care center(Sangikjae), and had the ability of verbal communication were selected from G city in Kyunggi province. The participants completed a set of questionnaires to measure the sub-score of frailty, fall, urinary incontinence, malnutrition, and mild cognitive disorder domain, using the Otasha-Kensin through the physical examinations and interviews. After 4 weeks of intervention, the outcome was measured to evaluate the effects of the program, and the data obtained were analyzed using descriptive statistics, paired t-test and McNemar test. The results showed that the sub-score of frailty, fall, urinary incontinence, and malnutrition domain were statistically significantly decreased after intervention except those of urinary incontinence and mild cognitive disorder domain, implying that the risk of frailty, fall, and malnutrition was decreased. These findings indicated that community-based the intensive health care program is effective for relieving geriatric syndrome of the community dwelling elderly.
