1.Comparative Analysis of Acute Drug Intoxication between 1980s and 1990s.
Journal of the Korean Society of Emergency Medicine 1999;10(3):441-446
BACKGROUND: To comparatively analysis the epidemiological changes in the acute drug intoxication between 1980s and 1990s. METHODS: We reviewed retrospectively the medical records of the patients with acute drug intoxication in the emergency department of the Inha hospital from June 1986 to April 1987 and from June 1996 to May 1997. And we performed comparative analysis between two result. RESULTS: The ratio of the acute drug intoxication in the emergency medical center was reduced significantly in 1990s against 1980s. Sexual ratio and prevalent age group has no significant interval changes between 1980s and 1990s. The prevalent seasons were Spring in 1980s and Summer in 1990s but has no significance. The most commonly used drugs was rodentides in 1980s and hypnosedatives in 1990s and shown significant interval changes. The most common motive was suicidal attempts in both 1980s and 1990s, but significantly reduced. After emergency treatment the rate of curative-discharge has improved and the rate of admission has decreased significantly in 1990s against 1980s. The most critical agent was agricultural chemicals in both 1980s and 1990s. The mortality rate has no significant interval changes. CONCLUSION: There were some significant interval changes of the acute drug intoxication in prevalence rate, commonly used drugs, ratio of suicidal attempt and curative-discharge rate between 1980s and 1990s. New education programs far preventing acute drug intoxication and strict legal control of drugs are important and necessary.

3.Clinical Study of Kienbock's Disease
The Journal of the Korean Orthopaedic Association 1990;25(5):1453-1461
Seventeen cases of Kienbock's disease were treated since 1982, and analysed their clinical outcomes to confine the pathogenesis and to make sure the best way to treat them in various stages. It was not related to trauma around wrist joint (35.3%) but significantly closed to ulnar negative variances(64.7%). Ulnar tilt angle was increased definitely upto 28.9° compared with normal value (22°) in ulnar negative variance, but volar tilt angle was within normal limits. The packing with tensor fascia lata or palmaris longus tendon after the complete excision of avascular lunate could not prevent the collapse of carpal bones at long-term follow-up. But the triscaphe fusion was most effective to maintain the normal wrist anatomy, and radial shortening than ulnar lengtherning is thought to be more effective in wrist biomechanics of kienbock's disease with ulnar negative variances.

Journal of the Korean Society of Emergency Medicine 1998;9(3):420-429
BACKGROUND: Dizziness is a common complaint in patients presenting to the emergency room and that has various pathologic causes. This study investigate the clinical differences in dizziness between the central origin and the peripheral origin and to provides the clues far diagnosis and proper treatment. METHODS: We analysed 290 patients with dizziness during 12 months period prospectively, who visited in ED, Inha University Hospital from Jan. 1997 to Dec. 1997. We analysized sex ratio, characteristics of the dizziness, associated past illness, associated symptoms, severity, results of the special radiologic study, nystagmus type, and causes of central origin and peripheral origin dizziness. RESULTS: Male to female ratio was 1:1.4 in central origin(n=165) and 1:2.0 in peripheral origin(n=125). Most common age group was 11th decade in both groups. According to the characteristics of the dizziness, rotation sense was the main complaint of the peripheral origin dizziness. Most common past illness was hypertension in both groups. MRI has diagnostic priority than CT scan in central origin dizziness. Types of nystagmus has some significant differences between two groups. CONCLUSION: Dizziness may represented as a sign of significant pathological neurologic status especially in central origin. So we must precisely evaluate the patient history, neurologic examination of the inner ear and CNS, and special radiologic study incliding MRI.

Cutaneous larva migrans(CLM) is a ubiquitous self-limiting skin eruption which has intensely pruritic, serpiginous, raised, sharply demarcated, red lesions. It is most frequently caused by larvae of dog and cat hookworms. We report two typical cases of cutaneous larva migrans that appeared as pruritic exanthems in two people after they had travelled in Southeast Asia. It is suggested one should consider cutaneous larva migrans in the differential diagnoses of erythematous pruritic lesions.

Infantile myofibromatosis is an uncornmon, benign, self-limiting, localized or generalized process, probably of hamartomatous origin, which consists to a large degree of cells having the characteristics of myofibroblasts and sometimes of pericytes. Both solitary and multicentric forms occur. Most lesions are present at birth or in early infancy, and some are familial in origin. A female newborn presented with a firm, round, red colored, 3 x 3 cm sized tumor with central necrosis on the left chest. Histological examination revealed well-circumscribed nodules consisting of short bundles of plump, spindle shaped cells displaying staining characteristics intermediate between fibroblasts and smooth muscle cells. The tumor was immunoreactive for actin but did not stain for desmin. A Follow-up examination at the age of 3 months revealed a moderate degree of spontaneous regressior of the lesion.

Korean Journal of Dermatology 1998;36(5):796-803
BACKGROUND: Generally, there are few problems in the diagnosis of Paget's disease(PD) using the H&E stain. However, the differentiation of PD from the clonal type of Bowens disease and superficial spreading melanoma in situ that shows pagetoid spreading of tumor cells, may present diagnostic difficulties. In addition, the specia1 stains used for demonstrating the presenee of Pagets cells, such as PAS and mucicarmim, are non-specific and not always sensitive. So, inenunohistochemical stains with monoclonal antibodies against various antigens may be helpful for differentiating PD from ather morphologically similar skin lesions. OBJECTIVE: The purpose of this study was to investigate the diagnostic accuracy of immunohisto- chemical staining for diagnostic use in PD. METHODS: Immunohistochemical stains used in the biotin streptavidin amplificxl technique with monoclonal antibodies to several low rnolecular weight cytokeratin(CK)s, EMA and CEA, were performed on formalin-fixed, paraffin-embedded tissue. Twelve cases of PD(10 cases of extranmmmary PD and 2 cases of mammary PD), five cases of superficial spreading melanoma in situ and five cases of Bowens disease were investigated. RESULTS: The results were as follows. 1. Positive reactions with variable intensity using CK7, CKS, CK19 were seen in all cases(100%) of PD and the. staining intensity tor CK7 or CK19 was stronger than that of CKS. 2. Of the 12 cases of PD, both CK18 and CAM5.2 staining showed positivity in 11 cases(92%). 3. EMA and CEA staining showed positivity in 10(83%) and 9(75%) of 12 cases, respectively. 4. Some Pagets cells were negative for CK8, CK18 and EMA, although other positive cells were observed in the same sections. 5. All antigens were consistently negative in all cases of Bowens disease and superficial spreading melanoma in situ. CONCLUSION: The results show that moaoclonal antibodies to low molecular weight CKs are more sensitive than EMA or CEA in the demonstration of Pagets cells. Moreover, among the low molecular weight CK series, CK7 and CK19 are most useful for their high sensitivity and intensity.
