PURPOSE: This study was done to examine the association between body mass index (BMI) and any type of clinical dementia. METHODS: Participants were 60,321 people over 60 years of age enrolled in the Seoul Dementia Management Project in 2011. K-MMSE was used to classify participants as having a cognitive impairment and the Clinical Dementia Rating or DSM-IV by psychiatrists or neurologists to determine whether participants were in the dementia group or the non-dementia group. Descriptive statistics, chi-square test, and binary logistic regression analysis were performed. RESULTS: In the univariate analysis, age, education level, living with spouse, BMI, alcohol consumption, and exercise were significantly associated with dementia. In multivariable analysis, increasing age was positively associated with dementia, and educational level was negatively associated with dementia. The exercise group had a lower prevalence of dementia than the non-exercise group. The odds ratio of dementia in the over-weight and obese groups compared to the normal group was 0.85 (95% CI 0.60, 0.98) and 0.64 (95%CI 0.46, 0.75), respectively. CONCLUSION: Results indicate that dementia is negatively associated with increasing BMI in people aged 60 years or older, but a prospective cohort study is needed to elucidate the causal effect relationship between BMI and dementia.

BACKGROUND: Pyoderma gangrenosum is a rare disease in which a painful nodule or pustule breaks down to form a progressive enlarging ulcer. Until now, only 8 cases of pyoderma gangrenosum have been reported in Korea. Therefore, we thought it necessary to perform a clinical analysis of pyoderma gangrenosum in Korea with a review of literature. OBJECTIVE: Our purpose was to find the clinical features of pyoderma gangrenosum in Korea. METHODS: Fourteen cases with pyoderma gangrenosum were investigated by reviewing medical records. Results There were 6 males and 8 females. The onset age was between 4 years and 65 years, and most(9 cases) had developed the condition between the ages of 20 and 60. Thirteen cases involved the extremities and 3 cases had whale body involvement, Seven cases(50%) had multiple lesions. All cases had pain at the lesional sites. Two cases were classified as the bullous type and the others were ulcerative in nature. The histological fmdings were non-specific. Dense inflarnmatory infiltrates composed of lymphocytes and predominant neutrophils were found in the epidermis and dermis associated with ulceration. Two cases were treated only with systemic steroids, and 2 cases with dapsone and steroids, 2 cases with colchicine and steroids, and 1 case with steroids, dapsone and colchicine. One case was treated with colchicine and anti-Tbc drug, 1 case with dapsone, 3 cases with antibotics, 1 case with the anti-Tbc drug and 1 case with anti-cancer drugs. Systemic disease was present in 5D% of the cases. The associated diseases were Behcets disease(3 cases), tuberculosis(2 cases), systemic lupus erythematosus(1 case), pancytopenia(1 case), iron deficiency anemia(1 case), acute leukemia(1 case), and colon adenoma(1 case). Recurrence developed in 2 cases and positive pathergy reactions were observed in 3 cases. CONCLUSION: Pyoderma gangrenosum was eccompanied with systemic disease in 50% of the cases and the most common therapeutic drugs were steroids. It is therefore impartant to detect the presence of any underlying disease and to treat this alongside pyoderma gangrenosum.

This study was undertaken to investigate the distribution of the chewing side preference and variations in the maximum bite force and facial morphology according to chewing side preference since unilateral chewing may cause morphologic and functional anomalies. 50 dental students who had no signs or symptoms of masticatory system and Angle's Class I relationship in posterior segments were selected, and divided into two groups, that is, 25 in bilateral chewing group(19 male and 6 female) and 25 in unilateral chewing group(10 male and 15 female). Maximum bite force was estimated and posteroanterior cephalogram were measured and statistically analyzed. The results were as follows: 1. There were more students with bilateral chewing side preference(68%) and unilateral chewing side group consisted of right side preference(68%) and left side preference(32%). 2. There was no significant difference in the strength of max. bite force between the right and left side in bilateral chewing group. The bite force of the chewing side was greater in the unilateral chewing group but less in the non-chewing side compared to those of bilateral chewing group with no significant difference. Max. bite force of chewing side was greater than that of non-chewing side in the unilateral chewing group(Female : p<0.05). Max. bite force of males was about twice in that of females in both groups(p<0.05). Max. bite force of chewing side of the unilateral chewing group was similar to that of the bilateral chewing group, but that of non-chewing side was less than that of the bilateral chewing group. 3. In comparison of the facial morphology, there was no statistically significant difference in the size between the right and left side of the bilateral chewing group and between chewing and non-chewing side of the unilateral chewing group.

PURPOSE: This study was done to compare demographic characteristics, comorbidity, and health habits of elders with mild cognitive impairment (MCI) and elders with cognitively normal function (CNF). METHODS: Secondary data analysis was conducted using data from the Database of the Seoul Dementia Management Project for 5,773 adults age 60 and above. RESULTS: The MCI group showed an older age distribution, but there was no significant education difference between the two groups. Elders with MCI had more diabetes and stroke than elders with CNF. In subgroups, the same findings were observed in women, but not in men. While more men with MCI had hypertension compared to men with CNF, there was no significant difference in hypertension between the two groups for women. Elders with MCI, men in particular, had a lower prevalence of obesity than men with CNF. MCI individuals did less exercise compared to individuals with CNF. While there were no significant differences in alcohol consumption and smoking between MCI and CNF groups, the over 80's subgroup with MCI reported more alcohol consumption. CONCLUSION: Findings from this study could be helpful in designing community-based dementia prevention programs and health policies to reduce the prevalence of dementia or related cognitive impairments.

Anesthesia for the patients with mediastinal mass may be associated with significant respiratory and cardiovaacular complications due to compression of traeheobronchial trees, the pulmonary artery, heart and superior vena cava The authors present a case of a 6-year-old girl with a large mediastinal tumor located in anterior and superior mediaetinum. Preoperatively, the patient was asymptomatic and anesthesia was induced and maintained uneventfully. Operative finding was that 8 X 14 cm sized hemangioma was extended superiorly over thoracic outlet, posteriorly aorta and SVC, medially pericardium and right hilum and inferiorly right upper lung and pleura. Because difficulties in removal of the hemangioma were expected, exploratory thoracotomy was discontinued. On emergence, as soon as the patient was extubated due to irritability, the patient became cyanotic and was noticed bulging mass on right supraclavicular area, Intubation was attempted and during direct laryngoscopy, anesthesiologist also noticed a bulging mass in right oral cavity. Postoperatively, the patients airway was kept with endotracheal tube, but cyanosis appeared on the face and skin over the chest, but not below the abdomen. Bulging mass on right supraclavicular area, distension of neck vein and conjunctival edema were noticed only when the patient was crying or suctioned. Symptoms improved by deep sedation. We assumed that enlargement of hemangioma due to increased central blood volume occasionally compressed tracheobronchial tree and sup. vena cava when patient was irritable, crying and coughing. On 11th postoperative day, patient was transferred to the another hospital for the better treatment with endotracheal intubation.

OBJECTIVE: The aim of this study was to investigate whether embryonic stem (ES) cells can be established from isolated blastomeres of mouse embryos. METHODS: Blastomeres were separated from mouse (C57Bl/6J) 2- or 4-cell embryos. Isolated blastomeres or whole 4-cell embryos were co-cultured with mitosis-arrested STO feeder cells in DMEM supplemented with recombinant murine leukemia inhibitory factor and ES-qualified fetal bovine serum. After the tentative ES cell lines were maintained from isolated blastomeres or whole embryos, some of them were frozen and the others were sub-cultured continually. Characteristics of tentative ES cell lines as were evaluated for specific gene expressions with immunocytochemistry and RT-PCR. RESULTS: One ES cell line (3.0%) was established from isolated blastomere of 2-cell embryo and one cell line (4.0%) from isolated two blastomeres of 4-cell embryo. And five cell lines (16.7%) were established from whole 4-cell embryos. Both cell lines from isolated blastomere and whole embryo expressed mouse ES cells specific markers such as SSEA-1, Oct-4 and alkaline phosphatase. Marker genes of three germ layers were expressed from embryoid bodies of both cell lines. CONCLUSION: This study suggests that mouse ES cells could be established from isolated blastomeres, although the efficiency is lower than whole embryos. This animal model could be applied to establishment of autologous human ES cells from biopsied blastomeres of preimplantation embryos in human IVF-ET program.

PURPOSE: To investigate the trend of refractive change in hyperopic patients according to increases in age. METHODS: Eighty-eight children who had hyperopia of more than +1.50 diopters (D) and could be followed up for at least 5 years were included in this study. We divided the patients into two groups according to the level of initial hyperopia and retrospectively analyzed hyperopic refractive changes over a 5-year period according to age at initial diagnosis, presence of esotropia, amblyopia, astigmatism and anisometropia. RESULTS: We gained the following formula about the aspect of hyperopic reduction in 88 patients over a period of 5 years: Diopter (D)=7.99-2.14 Ln (age). The presence of anisometropia and amblyopia did not affect hyperopic reduction. Hyperopic reduction amounts in the group with a hyperopic eye of more than +5D at initial diagnosis were greater than in the group with a hyperopic eye less than +5D, and greater in the group with an astigmatic eye of more than 1D. The presence of esotropia and the age at initial diagnosis did not affect hyperopic reduction. CONCLUSIONS: We show that emmetropization in hyperopic children occurs according to the following formula: Diopter (D)=7.99-2.14 Ln (age). Both the initial level of hyperopia and the concurrent presence of astigmatism affected hyperopic reduction. However, the presence of anisometropia, amblyopia, esotropia and the age at initial diagnosis did not significantly affect hyperopic reduction.

PURPOSE: The aim of this study was to clarify the actual condition of elders with dementia who were registered in the Seoul Dementia Management Project. METHODS: Data were collected from 5,312 elderly patients with dementia. Demographic included characteristics, comorbidity, and healthy lifestyle habits; data from the Seoul Dementia Management Project. RESULTS: First, demographic characteristics were as follows; mean age at the time of definite diagnosis was 78.0 yr. There were slightly more women (69.3%), and 4.55 yr was the average length of education with 41.4% being illiterate or uneducated patients. Second, there were several comorbidities including hypertension (61.7%), diabetes mellitus (31.8%), hypercholesterolemia (10.2%), heart disease (11.1%), obesity (4.2%), and stroke (21.4%). Third, alcoholic history was found in 11.8% of the patients, and smoking in 9.8%. Regular exercise was done by only 29.1% of the patients with dementia. Finally, significant differences between men and women were found for the following; age, education, medical security, hypertension, diabetes mellitus, stroke, alcoholic consumption, smoking, and regular exercise. CONCLUSION: Authors expect that the present data will be used for establishment of dementia associated projects and policies.

Aplasia cutis congenita is a congenital localized or widespread absence of the skin. We report a case of aplasia cutis congenita, type V, in a 6-day-old male infant born with the stellate and linear skin lesions covered by granulation tissue and soft capsule with slightly elevated erythematous edges on the trunk and lower extremities without any associated family history. The patient had amniotic bands and were diagnosed as aplasia cutis, type V. The patient received conservative treatment such as antiseptic dressing and prophylactic systemic antibiotics with healing of the ulcer.

PURPOSE: This study was carried out to accumulate basic data for nursing intervention development by evaluating the stress and emotional status of patients and their families after receiving hematopoietic stem cell transplantation (HSCT), illucidating and analysing related factors in order to decrease the negative effects of HSCT on their emotion. METHODS: Data were collected using a questionnaire to 53 HSCT patients and 50 families, who were older than 18 at tertiary-care institutions in Seoul, from January, 2000 to August, 2003. RESULTS: There was a significant score difference in stress (t=-2.302, p<0.05). Correlation between stress and emotional status was statistically significant (r=0.486, p<0.01; r=0, p<0.05). Economical burden of cost had significant effects on stress of patients (F=4.194, p<0.05). The series of emotional status of patients without jobs were higher (T=-2.583, p<0.05). The emotional status of families were influenced by monthly income (F=4.036, p<0.05) and patients' diagnosis (F=3.088, p<0.05). CONCLUSION: These results suggest that the cares for families should be considered with great concern as well as the ones for patients. In addition, such factors as economical burden by medical cost, monthly income and job status should not be excluded in transplantation nursing plans.
