PURPOSE: We wanted to evaluate the usefulness of three-dimensional reconstructive images using multidetector computed tomography (MDCT) for thoracic traumatic patients visiting emergency room. MATERIALS AND METHODS: 76 patients with fractures of the 105 patients who visited our emergency room with complaints of thoracic trauma were analyzed retrospectively. All the patients had thoracic MDCT performed and the three-dimensional reconstructive images were taken. The fractures were confirmed by axial CT, the clinical information, whole body bone scanning and the multiplanar reformation images. Plain x-ray images were analyzed by the fractured sites in a blind comparison of two radiologists' readings, and then that finding was compared with the axial CT scans and the three-dimensional reconstructive images. RESULTS: The fracture sites were rib (n=68), sternum (n=14), clavicle (n=6), scapula (n=3), spine (n=5) and combined fractures (n=14). Plain x-ray and axial CT scans had a correspondency of 0.555 for the rib fractures. Axial CT scans and the three-dimensional reconstructive images had a correspondency of .952. For sternal fractures, those values were 0.692 and 0.928, respectively. The axial CT scans and three-dimensional reconstructive images showed sensitivities of 94% and 91% for rib and other fractures, respectively, and 93% and 100% for sternal fracture, respectively. Three-dimensional reconstructive image had an especially high sensitivity for the diagnosis of sternal fracture. CONCLUSION: While evaluating thoracic trauma at the emergency room, the three-dimensional reconstructive image was useful to easily diagnose the extent of fracture and it was very sensitive for detecting sternal fracture.

The importance of the ticks in medical field has been emphasized because of their association with and transmission of various diseases. We report herein a case of tick bite in a 55-year-old male farmer, who visited our hospital on July 2, 1981 with a parasite attached on right lower flank and rice to small pea sized, pruritic erythematous papular skin eruptions on chest and right lower flank. The skin lesions disappeared completely with.in five days after removal of the parasite, which was identified with an adult female tick which belongs to Genus Ixodes.

4.Concepts of Occupational Exposure Limit and Their International Comparisons.
Korean Journal of Occupational and Environmental Medicine 1995;7(1):152-168
This paper focuses on the origin of the concepts of occupational exposure limit, and traces the history and development of thoughts and regislations of various countries and organizations concerning the founding principles upon which it is based. The concepts of establishing standards for occupational chemicals in workplace air constitute a social consensus or agreement about acceptable levels of occupational hygiene. The level of scientific development of a country and the discussion of experts in the field of occupational health play an important role. The physician in occurational health has to be especially concerned to discover and estimate the risks to anyone particularly susceptible to exposures within the hygienically acceptable conditions.

This study was performed to evaluate the diagnostic value of colposcopy by comparing colposcopic findings with cytology, histology of colposcopically directed biopsy and final biopsy result on hysterectomy. From January 1, 1988 to August 31, 1996, the colposcopic examinations was undertaken in 1200 patients, excluding grossly visible carcinoma of the cervix. The result were as follows : 1. Colposcopic examinations were satisfactory in 95.4% and unsatisfactory in 4.58%. 2. The accuracy rate of cytologic diagnosis was 73.1% and colposcopic impression was 93.1%. 3. The false negative rate of colposcopic impression was 2.6%, much less than 24,7% of cytologic examination. 4. The cytologic accuracy rate in cervicitis was higher than that of colposcopic impression but the accuracy rate of colposcopic impression in diagnosis of cervical intraepithelial neoplasia was higher than that of cytology. 5. Among 97 cases in which colposcopically directed biopsy were performed, more advanced lesion were disclosed in 12 cases(12.4%).

Carcinoma of the breast can produce cutaneous metastases which sbow highly diversified clinical pictures. The cutaneous metastases produce four definite clinical types: inflammatory carcinoma, telangiectatic carcinoma, nodular carcinoma, and carcinoma, en cuirasse. We present a case of 78-year-old nulliparous woman who had several painful dark purplish colored zosteriform papulovesicular eruptions, suggestive of herpes zoster, on the right breast, right axilla, scapular area, and upper arm for three month. Two month later, well dermacated linearly arranged erysipeloid eruptions appeared around the previous skin lesions and the right chest wall. Histopathological findings showed metastatic ductal carcinoma with massive vascular permeation but the primary focus was undetermined.

Reticulate acropigmentation of Kitamura, described first by Kitamura and Akam atsu in 1943, is a pigmentary disorder that may be determined by an autasomal dominant gene. Skin lesions are characterized clinically by depressed brownisL pigmented spots, in a reticulated pattern, on the extensor surface of the acral parts of the extremities. Most reported cases are confined to Japanese. We report herein a case of reticulate acropigmentation of Kitarnura in a 28- year-old woman, with a depressed brownish pigmented spots, in a reticulate pattern, on the dorsum of hands and left foot. The authors make the diagnosis of this case a reticulate acropigmentation of Kitamura for the clinical symptoms and histopathologic findings.

Digital mucous cysts encompass two pathogenetically distinct entities, the cutaneous myxomatous type and ganglion type. We describe an 8-year-old boy with a digital mucous cyst on the ventral side of the proximal phalanx of the right fifth finger. The case shows characteristic histopathological findings, but in an unusual location.

BACKGROUND: The oral ulcer is a common oral disorder, but the precise etiology remains elusive despite of intensive clinical, immunological, hematological and microbiological investigations. OBJECTIVE: The purpose of this study was to examine oral ulcers for the detection of HSV DNA by using PCR and to characterize clinical features of HSV DNA positive cases. METHODS: Specimens collected with cotton swabs and saliva from 48 cases of oral ulcers were examined for HSV DNA by PCR and Southern blot hybridization. RESULTS: 1. HSV DNA was detected in 8 of 48(16.7%) cotton swabbed specimens of oral ulcers and saliva by PCR and Southern blot hybridization. 2. Clinical features of HSV DNA positive oral ulcers were a. predominently located in buccal mucosa. b. mall sized(<3mm), multiple(> or =5) lesions. 3. In Behcet's disease, 2 of 7(28.6%) cases of oral ulcers were positive for HSV DNA CONCLUSION: PCR is an useful and accurate method for the detection of HSV DNA from cotton swabbed specimens of oral ulcers.

We report a case of focal eosinophilic myositis of the frontalis muscle in a 38-year-old man. The skin lesion was a single firm flesh-colored swollen lesion measuring 1×1.5 cm in size on the right forehead. The biopsy revealed inflammatory infiltrates composed of mainly eosinophils and a few lymphocytes in the muscles. The skin lesion subsided with intralesional injections of triamcinolone acetonide, 5 mg/ml.
