Nickel is widely known as a common source of contact dermatitis and nickel sensitivity amounts to nearly 10 percent of allergic contact dermatitis patients. Common sources of nickel dermatitis are well known as necklaces, watches, rings, hooks, earrings and spectacle frames. Recently, we have seen five cases of nickel dermatitis the suspected sources of which were metal spectacle frames. The interim patch test result in our occupational and environmental clinic suggests that the metal spectacle frame is one of the most common sources of nickel dermatitis. Out of 84 medical students 27 wore metal spectacle frames. We have done a dimethylglyoxime spot test to the metal spectacle frames and got a positive result in 12 out of 27(44.4%). We conclude that metal spectacle frame seems to be one of the dominant causes of nickel dermatitis and it will be an increasing problem in our society.

Estrogen and progesterone receptors exist in the epithelial and stromal cells of the endometrium. Proliferative disorders of the endometrium may be associated with autocrine and paracrine actions of estrogen and progesterone in epithelial and stromal cells. This study was performed to evaluate the differences estrogen and progesterone receptor(ER/PR) expression in the epithelial and stromal cells of endometrial hyperplasias and adenocarcinomas using immunohistochemical methods. Immunohistochemical analysis of proliferating cell nuclear antigen(PCNA) was done to evaluate a possible correlation between PCNA and hormone receptor expression. Evaluation was based on samples from 31 simple hyperplasias, 30 complex hyperplasias, and 32 adenocarcinomas. The immunohistochemical expression of ER, PR and PCNA in epithelial and stromal cells were examined according to a scoring system based on the percentage of positive cells and the staining intensity. The results were as follows; 1) The expression of ER and PR in epithelial cells showed a graded, significant decreases in simple hyperplasia, complex hyperplasia and endometrial carcinoma, in that order(ER: P=0.008, PR: P= 0.026). 2) PR expression in the stromal cells showed a significant decrease between hyperplasia and adenocarcinoma(P=0.003). The difference in ER expression was not significant. 3) In stromal cells, the decrease in PR expression was more prominent than the decrease in ER expression when complex hyperplasia was compared to simple hyperplasia. 4) The PCNA expression in simple and complex hyperplasia and adenocarcinoma was not higher than the expression of PCNA in nomal proliferative endometrium. There was no significant difference in PCNA expression between simple and complex hyperplasia and adenocarcinoma(P=0.073). 5) A negative correlation between PCNA and ER/PR expression was not demonstrated in simple and complex hyperplasia, or in adenocarcinoma. Endometrial hyperplasia and adenocarcinoma are probably related to a paracrine action of estrogen and progesterone in epithelial and stromal cells. A progressive loss of PR expression in stromal cells may induce abnormal proliferation of endometrium due to a disrupted hormonal balance.

A 40-year-old woman presented with a pruritic erythematous eroded patch on the right labium majus which had been for 3 years. Histopathological findings were consistent with superficial basal cell epithelioma. Basal cell epithelioma of the labium majus is a rare neoplasm and its clinical appearance is usually nodular. In contrast to the other types of basal cell epithelioma, the superficial type occurs mainly on the trunk. We report a case of superficial basal cell epithelioma arising from the labium majus.

The general elections for the 21st National Assembly in the Republic of Korea were scheduled for April 15th, 2020, which was during the novel coronavirus disease (COVID-19) outbreak. To ensure a safe election, the Korean Centers for Disease Control and Prevention (KCDC) recommended several public health measures. The KCDC developed key interventions after reviewing the general election strategy that targeted COVID-19 patients and individuals isolating at home. Four voters who participated in the election tested positive, but did not contract COVID-19 during voting. The results demonstrated that the KCDC minimized the spread of infection in the community during the election. The measures implemented by KCDC during the election held under a COVID-19 outbreak cannot be generalized to elections as a whole because cultural and national consciousness vary between countries. Nevertheless, it demonstrates that the systemic strategies and applications against the pandemic can minimize the possibility of viral spread.

This study was aimed to elucidate the relationship between combinations of treadmill speed-grade and oxygen consumption(Vo2). Twenty athetic and 20 non-athletic male college students aged 19-24yr were employed to exercise on a treadmill using 4 speeds(4.02, 5.47, 6.76 and 8.05km/h) and 5 grades(0, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The Vo2, heart rate, stride frequency and stride length were measured during the last min of each 3-min stage. Vo2increased linearly with increasing speed and grade showing significant multiple correlations in nonathletes(Vo2=3.64x+0.831y+0.031xy-7.03, R=0.98, P<0.01) and athletes(Vo2=3.48x+0.324y+0.112xy-5.74, R=0.99, P<0.01). Stride frequency and length tended to increase with increasing speed except for the transition from walking to runnig at 8.05Km/h at which the stride frequency ran up much higher with the stride length getting lower than at 6.76Km/h. Heart rate increased linearly with increasing Vo2. The rate of increase was higher during walking than during running. These results indicate that athletes have higher rate of increase in Vo2than nonathletes at near-maximal exercise and may be used as a guideline in predicting maximum oxygen comsumption and in prescribing exercise intensity.

PURPOSE: The purpose of this study was to evaluate the effect of the zirconia surface architecturing technique (ZSAT) on the bond strength between veneering porcelain and zirconia ceramic. MATERIALS AND METHODS: 20 sintered zirconia ceramic specimens were used to determine the optimal surface treatment time, and were randomly divided into 4 groups based on treatment times of 0, 1, 2, and 3 hours. After etching with a special solution, the surface was observed under scanning electron microscope, and then the porcelain was veneered for scratch testing. Sixty 3 mol% yttria-stabilized tetragonal zirconia polycrystal ceramic blocks were used for tensile strength testing; 30 of these blocks were surface treated and the rest were not. Statistical analysis was performed using ANOVA, the Tukey post-hoc test, and independent t-test, and the level of significance was set at α=.05. RESULTS: The surface treatment of the zirconia using ZSAT increased the surface roughness, and tensile strength test results showed that the ZSAT group significantly increased the bond strength between zirconia and veneering porcelain compared to the untreated group (36 MPa vs. 30 MPa). Optimal etching time was determined to be 2 hours based on the scratch test results. CONCLUSION: ZSAT increases the surface roughness of zirconia, and this might contribute to the increased interfacial bond strength between zirconia and veneering porcelain.

The syndromes of left atrial isomerism and right atrial isomerism, called polysplenia and asplenia syndromes, respectively, consist of congenital heart defects with disturbances in normal left right isometry, and the etiology of atrial isomerism remains unclear. Right atrial isomerism is traditionally associated with severe cardiac defects, especially complete atrioventricular septal defect, transposition of great arteries, pulmonary atresia, and total anomalous pulmonary venous return. Recently, we encountered one case of asplenia diagnosed by prenatal ultrasonography. We report a case with brief review of the literatures.

Diencephalic syndrome is a rare cause of failure to thrive in infancy and early childhood. The syndrome is characterized by profound emaciation with normal appetite, loss of cutaneous adipose tissue, hyperactivity, euphoria, and nystagmus. It commonly occurs in association with chiasmatic and hypothalamic gliomas. It has also been described in association with other histologic types. There is the marked increase of serum growth hormone, which may exhibit an inappropriate, even paradoxical response in stimulation test. A male infant of 12 months of age, showed markedly elevated growth hormone but he had failure to thrive findings. Evenly enhanced round mass was seen at suprasella area in brain CT. Its histological findings was "Desmoplastic infantile ganglioglioma", very rare histologic type. Here we report a case of diencephalic syndrome presented by failure to thrive in association with hypothalamic tumors.
