Hantavirus is a genus of the Bunyaviridae family consisting following serotype groups: Hantaan, Seoul, Puumala, Prospect Hill, Thailand, Belgrade, Thotta palayam, Sin Hombre. Most of Hantavirus group have been associated with many clinically similar disease known collectively as hemorrhagic fever with renal syndrome (HFRS). Hantaan virus is the prototype of the genus hantavirus, originally isolated from Apodemus agrarius. Bat was found as a natural host for Hantaan virus in Lee's lab for the first time. Then, Hantaan-like virus was isolated Hantaan-like virus from bat. To identify hantaviruses that are present in Korea among bats, bats were collected from Jeong-Sun, Won-Joo, Chung-Ju and Hwa-Cheon area, RNA was isolated from lung and serum. RT-PCR was performed with a universal primer from M segment. Nested RT-PCR was carried out to differentiate Hantaan, Seoul and Puumala virus using serotype specific primers. As we expected, Hantaan viruses were detected in bats and Seoul virus was not detected. Interestingly, Puumala viruses were also detected in bats from won-Ju, but not in other areas. Puumala virus is originally isolated from Clethrinomys glareolus, and cause light HFRS. Recently, Paradoxomis webbiana, a wild bird turn out to be a reservoir for Puumala virus in Korea. These data indicate that bat is a new natural reservoir of Puumala virus.

Hantavirus is a genus of the Bunyaviridae family causing two serious diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Puumala virus is a member of hantavirus originally found in Europe, and its natural reservoir is Clethrionomys glareolus. It is also associated with the hurnan disease nephropathia epidemica, a milder form of HFRS. To identify the hantaviruses in bats, bats were collected from Jeong-Sun, Won-Joo, Chung-Ju and Hwa-Cheon area in Korea, and nested RT-PCR was performed with serotype specific primer from M segment. Interestingly, Puumala virus was detected in bats (Rhinolophus ferrum-equinum) only from Won-Joo. The 327 bp nested RT-PCR product, was sequenced. The sequence database search indicates that the sequence is homologous to the published sequence of Puumala viruses. The sequence similarities were ranged from 71% to 97%. The highest sequence similarity was 97% with Puumala virus Vranicam strain, and the lowest was 71% with Puumala virus K27 isolate. Puumala virus Vranicam strain was isolated from a bank vole (Clethrionomys glareolus) in Bosnia-Hercegovina. Puumala virus K27 was isolated from human in Russia. This analysis confirms that bats (Rhinolophus ferrum-equinum) in Korea are natural reservoir of Puumala virus.

We experienced a case of cutis laxa in a 17-year-old man. The skin showed diminished elasticity with loose folds, wrinkling, and sagging on the abdomen, lower back, and both inner thighs. There was no history of any inflammatory skit diseases prior to the appearance of the wrinkling. Family history revealed to be negative for the skin diseases showing wrinkling and laxity. The biopsy specimen from the skin of the abdomen showed shortened, fragmented elastic fibers in the dermis. The serum copper level was normal(92 ug/dl).

OBJECTIVES: Recent studies have reported a correlation between obstructive sleep apnea syndrome (OSA) and depression. In attempt to verify the suggestion that eveningness is related to depression, we examined the effect of morningness-eveningness on their depressive mood in patinets with OSA. METHODS: The examination was based on the medical records and polysomnography reports of 211 OSA patients. Information was gathered from the patients who filled out the Horne and Ostberg questionnaire (HOQ), profile of mood states-Korean version (K-POMS), and Epworth sleepiness scale (ESS). We compared mean values of K-POMS total, subscales of K-POMS, ESS, and OSA severity variables among the 3 morningness-eveningness groups (morningness, eveningness, and neither groups). Partial correlation analysis was performed between variables and ANCOVA was performed among the 3 groups after adjustment with age and weight. RESULTS: There were significant negative correlations between HOQ and the followings : K-POMS total, POMS-T (tension-anxiety), POMS-D (depression-dejection), POMS-A (anger-hostility), POMS-F (fatigue-inertia), POMS-C (confusion-bewilderment), spontaneous arousal index, average O2 saturation. There were significant positive correlations between HOQ and the followings : POMS-V (vigor-activity), apnea-hypopnea index, respiratory arousal index, snore time. There were significant negative correlations between POMS-D and the followings : HOQ, POMS-V, stage 1 sleep (%), AHI, TAI (total arousal index), oxygen desaturation index, respiratory arousal index, neck circumference, average O2 desaturation, snore time (%). There were significant positive correlations between POMS-D and K-POMS total, POMS-T, POMS-A, POMS-F, POMS-C, sleep latency, stage 2 sleep (%), heart rate, spontaneous arousal index. There were significant differences in K-POMS total, POMS-T, POMS-D, POMS-F, POMS-C, spontaneous arousal index among the three HOQ groups in ANCOVA. CONCLUSION: The depressive correlates of OSA patients might be affected, not by excessive daytime sleepiness or OSA severity indexes, but by eveningness circadian characteristics. It would be important to take into account the morningness-eveningness tendency when we manage the depressive mood of OSA patients.

Acquired tufted angioma is a benign, slowly progressive angioma with a typical histological pattern that was first described by Wilson-Jones in 1976. We report a case of acquired tufted angioma in a 19 year old female who had erythematous papules and plaques on the right thigh. Histopathological findings showed multiple capillary lobules in a cannonball arrangement scattered throughout dermis, which was diagnostic of acquired tufted angioma.

Nodular fat necrosis is a rare and often overlooked sign of pancreatic disease. It is manifested as painful subcutaneous erythematous nodules, often found on the legs. We report a case of nodular fat necrosis associated with pancreatitis. The patient was a 14-year-old girl who presented with erythema nodosum-like tender subcutaneous nodules on both her lower extremities. The serum amylase and lipase levels were markedly elevated. The change of serum calcium and eosinophils were not so remarkable. Histopathological findings showed diffuse subcutaneous fat necrosis and ghost-like cells with thick shadowy walls and no nuclei. The lesions involuted gradually without any specific treatment and the underlying pancreatitis was followed up in the department of medicine.

We experienced a case of erosive adenomatosis of the nipple (EAN) in a 20-year-old lady. She have had an eczematous, erosive and crusted nipple, on the right si.de, with a serosanguineous discharge for the past two years. The biopsy specimen of eczematous lesion on the affected nipple showed focal erosion and acanthosis in the epidermis. Florid intraductal epithelial proliferation and solid nests were scattered in the nipple stroma without showing any cellular pleomorphism. The lining epithelium maintained two layers of cells the inner colurnnar cells and the outer cuboidal cells. Chronic inflammatory infiltrates of relatively dense lymphohisiocytes were found in the surrounding stromal tissue, Paget cells or underlying malignancy were not seen, and a group of tumor netst was confined to the upper part of the subareolar tissue.
