Background: Although actinic keratoses is the most common precancerous cutaneous lesion, there has been no clinical and histopathological study about actinic keratoses in Korea. Objective : Our purpose was to carry out a clinical and histopathological study about actinic keratoses in Korea. Methods : 158 patients, diagnosed with actinic keratoses from 1987 to 1995 in Korea, were analyzed clinically and histopathologically. Results 1. The ratio of males to females was 1:2.4 and the most frequent age groups were the 6th(29.1%) and 7th decade(33.5%). 2. The duration of the lesions was more than 1 year in most cases. 3. The most commonly involved sites were the face, in which the cheek, nose and forehead were the most common sites. 4. Clinically, the size of the lesions was less than 1cm in many cases(66.8% ). The color was erythematous in 57.9%, brownish in 26.7%, and dark brownish in 15.3%. Crust and scale were noted in 28.7% and 25.2%, respectively. In 4% of patients, cutaneous horn also was noted. 5. Squamous cell carcinoma was associated with actinic keratoses in 5.7%, basal cell carcinoma in 3.2%, and keratoacanthoma in 1.3%. 6. Histopathologically, hypertrophic types of actinic keratoses were noted in 25.0%, atrophic types in 21.3%, hypertrophic and atrophic types in 18.1%, bowenoid types in 17.6%, acantholytic types in 13.3%, and pigmented types in 4.7%. 7. The most commonly used methods of treatment for actinic keratoses were cryotherapy, surgical excision, 5 FU ointment, and electrodesiccation with good effect. Conclusion : Actinic keratoses in Koreans was present on the face most commonly over 50 years of age. It showed a more frequent incidence in females than males. The clinical course of the lesions was chronic and the association with other cutaneous malignancies was noted to be less than 6%. The various histopathological types were noted, including hypertrophic, atrophic, hypertrophic and atrophic, bowenoid, acantholytic, and pigmented. The most commonly used methods of treatment. for actinic keratoses were cryotherapy, surgical excision, 5-FU ointment, and electrodesiccation. (Korean J Dermatol 1997;35(5): 931-939)

In order to examine the role of emotional labor in detail, this study investigated the following simultaneously, 1) the effects of two types of employee’s motivation (intrinsic motivation and extrinsic motivation) on two types of emotional labor (deep acting and surface acting), and 2) the impacts of two types of emotional labor on employee creativity, 3) the influence of employee creativity on service performance. To test the proposed model empirically, the survey was performed with employees who work for travel agencies over one year, and 234 samples were used for the data analysis. The analysis results from SEM(structural equation modeling) showed that 1) Intrinsic motivation influenced only deep acting, while extrinsic motivation negatively influenced deep acting and positively influenced surface acting, 2) only deep acting had a positive effect employee creativity significantly, 3) employee creativity was significantly positively correlated with service performance. Based on these findings, managerial implications were suggested for effective management of emotional labor to enhance employee creativity and service performance.

Hypertrophic cardiomyopathy (HCM) is the most often seen type of cardiomyopathy in cats. The cause is unknown but a genetic basis is thought to underlie some cases. Thromboembolism (TE) is a troubling complication in cats with myocardial disease. Two cats referred to Seoul National University Hospital for Animals with the paralysis of bilateral hindlimbs after vomiting. The cats were depressed and the bilateral hindlimbs were cyanotic, cool and painful. Heart murmur sounds were auscultated in both cases. Through radiographic and echocardiographic evaluation, HCM was diagnosed. TE at the distal aortic trifurcation was also visualized on abdominal ultrasonography. Both cats were expired and HCM and saddle thrombus were confirmed by postmortem examination in one cat.

A 10-year old female Yorkshire terrier with nasal discharge and swelling was referred to the local animal hospital. Abnormal mass of right nasal cavity was detected in physical examination and radiography. According to the radiographs of the head, there was an evidence of bony destruction in right nose. Oronasal fistula was detected in right maxillary canine teeth. After surgical excision, the sample of nasal mass was refereed to Pathology Department of Veterinary Medicine in Jeju National University. Grossly, the enlarged mass was soft and 3 ${\times}$ 3 cm in size. Histopathologically, the neoplastic mass was composed of tubular to tubulopapillary structures which were lined by single to 6~7 layers of cuboidal to ciliated columnar cells. These neoplastic cells showed invasive tendency to adjacent normal parenchyma. They had uniform, round to oval nuclei, cytoplasm with small vacuoles and indistinct cellular margin. The number of mitotic figures was varied in different areas, ranged from 0 to 4 per high power field. Necrotic foci and infiltration of inflammatory cells including neutrophils, lymphocytes, and plasma cells also presented in the mass. Immunohistochemically, the neoplastic cells demonstrated strong positive reaction for cytokeratin (CK) 18 but were negative for CK 7 and 8. Based on the gross, histopathology and immunohistochemistry, this mass was diagnosed as nasal adenocarcinoma originated from respiratory epithelium.

Objective: Juvenile rheumatoid arthritis (JRA) is classified as polyarticular, oligoarticular, and systemic onset type by clinical symptoms presented during first six months. This study was performed to investigate the clinical features and course of systemic onset JRA. Methods: We performed a retrospective study for patients who were diagnosed as JRA between March 2000 and March 2006 according to the JRA criteria of the International League of Association for Rheumatology (ILAR). Results: Of the 216 JRA patients, 33 patients (11 male/ 22 female) were systemic onset type. Because of insufficient data, 6 patients were excluded. Chief complaints at the time of diagnosis were fever (81.5%) and arthralgia (77.7%). During the disease course, all patients manifested fever and arthritis, rash (59.2%) and splenomegaly (22.2%) also occurred. Most patients had symmetric (81.5%) arthritis, and involved more than five joints (59.3%) including knee and wrist. Anemia, leukocytosis, and thrombocytosis were common laboratory abnormalities. Almost all patients had elevated level of C-reactive protein and erythrocyte sediment rate. Some patients had positive results about immunologic marker such as rheumatoid factor (3.8%), antinuclear antibody (57.7%), and antiperinuclear factor (9.5%). Therapeutic regimens included glucocorticoids (88.9%), nonsteroidal anti-inflammatory drugs (81.5%), methotrexate (81.5%), and hydroxychloroquine (55.6%). Biologic agents were applied in 5 patients, and 3 showed improvement of disease activity. Combination therapy was introduced in 18.5% of patients, and 63% of patients still required medications. Conclusion: In Korea, systemic onset JRA patients had variable clinical manifestations and chronic course of disease, which often extended into adulthood.
