We report a case of primary cutaneous cryptococcosis on Rt. forehead and perioral area of 57 year old woman with non-insulin dependent diabetes mellitus and Lt. cerebral infarction. She had large ulcers with yellowish purulent exudates on Rt. forehead and perioral area for 2months. A histopathological examination from the lesion showed numerous encapsulated, round spores and the organisms were identified as Cryptococcus neoformans in a series of fun-gal studies. The patient received a 5-week course of IV and oral fluconazole with resolution of her skin lesion. The patient is free of any lesion several months after completing therapy. This experience supports the use of fluconazole as initial and single therapy in primary cutaneous cryptococcosis.

BACKGROUND: Sun exposure and therapeutic irradiation have been shown to induce alterations in extracellular matrix (ECM) proteins, including elastin, glycosaminoglycan and collagens. The integrity of the connective tissue mainly depends on balanced rates of matrix synthesis and degradation of the extracellular matrix. Therefore, matrix metalloproteinases (MMPs) may be involved in ultraviolet irradiation (UVR)-induced alterations in ECM proteins. OBJECTIVE: To evaluate the effects of UVA as well as UVB irradiations on ST-1 gene expression in cultured human skin fibroblasts. METHODS: After exposure of different doses of UVA and UVB on cultured human skin fibroblasts, we examined the expression of ST-1 gene by Northern blot analysis, chloramphenicol acetyltransferase (CAT) assay with CAT construct containing AP-1 binding site. Additionally, we carried out the gel mobility shift assay to investigate the effects of UVR on the DNA-binding activity of AP-1. RESULTS: After UVR on fibroblasts, the steady-state levels of ST-1 mRNA were in-creased in response to UVA and UVB by 2.5-fold and 4.2-fold, respectively, as compared with controls. Similar results were obtained by CAT assay showing that CAT activity increased as the UVA and UVB doses increased. Furthermore, gel mobility shift assay demonstrated that both UVA and UVB increased AP-1 DNA binding complexes. CONCLUSION: UVB as well as UVA up-regulated ST-1 gene expression at transcriptional levels in vitro. We speculate that modulation of MMPs, including ST-1, gene expression by UVR may contribute to the connective tissue damage related to photoaging and other photocutaneous disorders.

Fractures of tibia are often trouble-some because of their easy compounding and associated soft tissue injury, especially neurovascular tissue. Initial proper treatments for fractures of tibia with severe compounding are very important for a better prognosis. In the orthopaedic Department of the Seoul Adventist Hospital, open reduction and internal fixation with Sherman plate were performed for 12 cases of tibia with severe compounding from January 1975 to October 1980 and the results were as follows; 1. The age of the patients ranged from 11 years to 50 years, and the majority of the patients were injuryed in traffic accident. 2. All of the patients were suffered from combined injures, so intensive close treatment was needed but 2 patients expired. 3. 7 out of 12 cases were found as vascular rupture and therefore 2 B-K amputations were carried out because of necrosis. 4. Average time for bone union was 6.9 months and infection was controlled without sequela. 5. Outcome of open reduction and internal fixation with Sherman plate for fractures of tibia with severe compounding was rather good, but comparisons are thought to be required after standardization of patients for open reduction without internal fixation. and openreduction with internal fixation.

Three-dimensional (3D) structure of the bronchopulmonary segments should be understood for accurate diagnosis and treatment of lung diseases. Two-dimensional (2D) tools (e.g. anatomy books) or traditional 3D tools (e.g. plastic models) are not sufficient for understanding 3D structure of the bronchopulmonary segments. The lung of a cadaver may not always be available for dissection, when it is needed. To overcome this problem, virtual dissection programs of the lung have been made. However, most programs include either 2D images that do not permit free dissection or radiographs that do not reveal true color and have limited resolution, and cannot represent 3D structure of the bronchopulmonary segments. Moreover, it is necessary to make a virtual dissection program of each race and ethnic group. Thus, we attempted to make a 3D image and virtual dissection program of the lung using a Korean cadaver in order to help medical students and doctors better understand 3D structure of the bronchopulmonary segments. One pair of lungs was extracted from a Korean male cadaver. Dye with specific color was injected into each segmental bronchus to distinguish bronchopulmonary segments. The lungs were embedded with gelatin solution, and serially-sectioned with 1 mm- thickness using a meat slicer. Sectioned specimens from each lung were inputted into the computer using a scanner (300 X 400 resolution, true color). 2D images of the lungs were aligned on the alignment program which was composed using IDL language. In 2D images, the bronchopulmonary segments were manually segmented by help of dye. 3D images of the bronchopulmonary segments were reconstructed through the volume-based rendering of 2D images. With 3D images as the main features, the virtual dissection program of the bronchopulmonary segments was composed using IDL language. Various virtual dissection functions, such as sectioning a lung at free angles to show its plane, identifying the bronchopulmonary segments represented in the sectioned plane, and rotating the selected bronchopulmonary segments at free angles, were established. This virtual dissection program of the bronchopulmonary segments is helpful in better understanding 3D location and shape of the bronchopulmonary segments; it is expected to be used through CD-title or Internet as an educational tool for medical students and doctors.

BACKGROUND: Suction auto epidermal graft for the treatment of stable vitiligo has become popular clinically. In general, depigmented epidermis is removed by liquid nitrogen freezing for preparation of the recipient site. There have been some problems with the nitrogen freezing method, uneven repigmentation, appearance of Koebner's phenomenon on normal colored skin around the graft site, scar formation on recipients sites. In our view these resulted in unwanted damage to the dermis and epidermal and skin appendageal melanocytes of normal skin by freezing. OBJECTIVE: To introduce a method to remove the depigmented epidermis of recipient site with minimal unwanted damage to melanocytes and dermal tissue. METHODS: Using Ellman surgitron, irradiation equipment of 3.8MHz frequency the depigmented epidermis was removed with a blade electrode under rated electric power around 10 watts depending on the thickness of the epidermis. Operating mode was fully filtered current for minimal charring and destruction of tissue through pure micro-smooth cutting. RESULTS: In the case of removal of the epidermis with Ellman surgitron, oozing and inflammation decreased markedly compared with those applied with liquid nitrogen. And it was confirmed histopathologically that there was no significant unwanted destruction of healthy tissue. Moreover, the electrode of Ellman surgitron is designed to be apt to trace the margin of depigmented lesion. And Ellman surgitron features a continuously linear intensity setting for precise, predictable control to minimize tissue destruction and charring. So we were able to remove the epidermis of the shallow lesion looking like a pseudopod and of the thinnest part of the body like eyelid also. And we grafted normal epidermis successfully on the depigmented lesion. CONCLUSION: The removal of depigmented epidermis by radio-frequency gave satisfactory results in the suction auto epidermal graft by overcoming the defects shown as depigmented epidermis which were removed by liquid nitrogen freezing. And this method made patients comfortable because of less pain, a one day operation procedure and good results.

Hydroxyurea is an effective treatment for a variety of myeloproliferative disodrers. A distinct cutaneous reaction to long-term administration of hydroxyurea has been characterized and designated hydroxyurea dermopathy. Epidermal dysmaturation refers to histologic changes that may be observed in the epidermis after any significant cytoreductive therapy. We report a patient with hydroxyurea-induced dermatomyositis-like eruption showing epidermal dysmaturation who developed an erythematous scaly patches on the dorsal aspects of the hands while on long-term administration of hydroxyurea for chronic myelogenous leukemia.

Confluent and reticulated papillomatosis(CRP) is a rare dermatosis. The lesions are hyperkeratotic, verrucous papules and plaques, resulting in a confluence of lesions centrally and a reticulated pattern at the periphery. It is more common in women and during puberty. The histopathological findings show papillomatosis, hyperkeratosis and a sparse superficial perivascular lymphocytic infiltrate. We report a case of CRP that responded to oral etretinate in an 18-year-old man.
