Serosurveillance and establishment of a reverse transcription-polymerase chain reaction assay for bovine parainfluenza virus type 5 / 대한수의학회지

Bovine parainfluenza virus type 5 (bPIV5) was isolated from cattle with downer cow syndrome in 2012, and included both respiratory and neurotropic pathogens from a variety of animals. In the current study, we conducted serosurveillance using sera obtained from seven Korean farms and optimized a reverse transcription-polymerase chain reaction (RT-PCR) assay to detect bPIV5. The overall seropositive rate for Korean cattle was 21.4% (163/760). A farm located near the city of Milyang in Gyeoungnam province had a markedly elevated seropositive rate for bPIV5 compared to that of the other six farms. The regional seropositive rates were 4.2% (8/192) for Haman, 19.5% (18/55) for Hwasung, 73.9% (65/88) for Milyang, 26.0% (50/192) for Namwon, 1.0% (1/96) for Uljin, 13.5% (13/96) for Yeongju, and 32.7% (8/41) for Yongin. The sensitivity and specificity of three RT-PCR primer sets used to amplify the conserved fusion gene of bPIV5 were also evaluated. An RT-PCR assay using the bPIVFR3 primer set was 10-fold more sensitive than the assays using the two other primer sets and did not result in non-specific amplification. These results demonstrated that the bPIFR3 primer set can be used to detect bPIV5.

Von Recklinghausen' s Disease with Plexiform Neurofibroma , Giant Pigmentation , and Skeletal Abnormalities / 대한피부과학회지

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

Clinicopathologic Study of Pustular Drug Eruption / 대한피부과학회지

BACKGROUND: Pustular eruptions due to drugs are uncommonly reported. We studied the characteristics of clinical and histopathologic findings of pustular drug eruption. OBJECTIVE: We observed th.e causative agents, clinical featurs and histopathologic findings of pustular drug eruption and identified differential points of generlized pustular eruption. METHODS: We evaluated t,he clinical and histopathologic findings of 8 patients with pustular drug eruption and reviewed the literatures reported cases of pustular drug eruption. RESULTS: All patients diagnosed pustular drug eruption suffered from generalized pustular eruption associated with systemic symptoms such as fever, headachened myagia one to three days after treatment with causative agents. The causative agents of putular drug eruption are antibiotics such as ceftriaxone, analgesics and antipyretics. The pustule resolved after a few days of treatment with systemic corticosteroids and antihistamines. Laboratory findings revealed leukocytosis, neutrophilia, and analevated erythrocyte sedimentation rate, On histopatologic findings, we observed subcorneal pustuls containing neutrophils, eosinophils and some lymphocytes and spongiosis, exocytosis of acute iiflammatory cells. Perivascular infiltration of lymphocyte ancl edema of papillary dermis was also bserved in the dermis. CONCLUSION: Pustular drug eruption is characterized by generalized pustular eruption associated with systemic symptoms and histopathologic findings of that are sterile subcorneal pustules. Therefore differential diagnosis of other generalized pustular erupticns are relatively easy by careful history of medication, clinical and histopathologic findings.

Cryotherapy of Alopecia Areata / 대한피부과학회지

BACKGROUND: 1. Conventional topical treatments of alopecia areata such as intralesional injection and topical application of glucocorticosteroids, and induction of conttact sensitivity using DPCP have had dieadvantages as follow 1) a time -consuming treatment perioed 2) various forms of discomfort during and after treatment 3) many side effects. 2. Though hair follicllee are easily damaged by intense cryo-application, we anticipate the regrowth of hair without damage to the tissue when applied to the scalp lightly OBJECT: We evaluated the efficacy of treatment and side effect of cryotherapy in patients with alopecia areata and whether this method can be used for the firstiline treatment of small alopecic patches, avoiding the above disadvantages of conventional methods METHOD: 19 patients witt alopecia areata lesion(s) confined within one fourth of the totaI scalp area were treated by dip-stick method with liquid nitrogen once a week luring the first 4 weeks, then at a two week interval. A cotten tip was lightly applied to the alopecic, patches for one to two seconds. We surveyed side effects and regrowth of hair during a periodic follow up. RESULT: The results can be summurized as follows : 1. Therapeutic responses were noted in 17(89%) of 19 patients studid. 2. In all the patients who responded, vellus hair appeared within 4 weeks of treatment, and terminal hair appeared within 6 weeks of treatment. 3. There were no specific fectors showing statistical significance between therapeutic responses. 4. There were no significanf, side effects except very faint pain during cryoapplication. 5. Recurrence was observed in only patieni during a 9-12 months follow-up CONCLUSION: Cryotherpy of the alopecia areata can be regarded as an effective mode of treatment with many advantages. These include relatively good therapeutic results, short-term treatment, a simple and convenient method, and nearly no side effects. We recommerld cryotherapy as a first-line mode of treatment of alopecia area.ta lesions which are small in size and few in number.

Preservation of antigenicity of autoimmune blistering diseases according to different methods of dermo-epidermal separation / 대한피부과학회지

There are many known methods of dermo-epidermal separation for the investigation of autoimmune blistering diseases. Investigators should select a proper method since many differences exist preservation of antigenicity. In order to determine the stabilization of antigenirity by different separation methods, we have separated dermo-epidermal junction by means of 1M s;ilt, 56C PBS, 20mM EDTA and dispase. Indirect immunofluarescence and immunoblotting were performed on each specimen with sera of patients with pemphigus vulgaris, pemphigus foliaceus, paraneoplastic pemphigus, bullous pemphigoid and epidermolysis bullosa acquisita. The results are as follows : 1. In indirect immunofluorescence study of pemphigus group, best, result were obtained when normal skin without dermo-epidermal separation was used. Dispase well preserved antigenicity of pemphigus after dermo-epidermal separation, but no differences were noted in antigenicity stabilization among separation mehods by immunoblotting. 2. In indirect immunofluorecence study for differentiation of bullous pemphigoid and epidermolysis bullosa acquisita, we recommend EDTA and dispase methods in addition to 1M salt induced skin separation that have been most popularly used. 3. Results of the immunoblotting of bullous pemphigoid showed that 1M salt, EDTA and heat preserved the antigenicity well but the antigenicity was lost by dispase. 4. Results of the immunoblotting of epidermolysis bullosa acquisita she wed that antigen did not exist in epidermal extract. 5. Antigen preservation according to the different methods of demo-epidermal separation was not identical between indirect immunofluorescence and immunoblotting.

A clinical and histopathologic study of epidermal cysts / 대한피부과학회지

BACKGROUND: Epidermal cyst is a common disease. The clinical and histo pathologic findings in patients with epidermal cysts are described. OBJECTIVE: Our purpose is to identify the clinical and histopathologic feastures of epidermal cysts. MEHTODS: We ealuated the clinical and histopathologie features of 11 cases which were diagnosed with epidermal cysts at the department of dermatology in Wonju Chist.an Hospital and Jeju Severance Dermatologic clinic for 13 years, from January 1980 to June 1992. RESULTS: The ratio of males to females was 1.9: 1 with male predominance. Age distribution at first visit was variable, ranging from to 85 years old. The mean age was 3.5 years old. The Duration of lesions was variable, ranging from a 3 days to 20 years, with the mean duration of 2.4 years. The most common site of lesions was the face(36%), followed by the trunk(18%), neck(13%), leg(13%), arm (8%), scalp(3%), scrotum(3%), vagina(3%), palm(1%) and fingers(1%). Histopathologically, 46 cases(41%) were ruptured. The most common stromal change was fibrosi followed by granulation tissue formation, giant cell, calcifiration, pilomatricoma like change, pigment, squamous eddy, bone formation and vessel proliferation. The most common cystic content was keiatinous material followed by parakeratotic cell, bacterial colony, calcification, cholesterol cleft, pigment and RBC. The most common cystic wall change was acanthosis followed by atrophy, hyperplasia, hyergranulosis, basalioma like change, parakeratosis and reticulation. CONCLUSION: Epidermal cysts are slowly growing tumors. They occur nost commonly on the face, trunk, neck, legs and arms. Histopathologically, they have a wall compose 1 of true epidermis. When an epidermal cyst ruptures, a foreignbody reaction with numerous multinu leated giant cells occurs.
