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.

Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However, it remains difficult to differentiate cystadenoma from cystadenocarcinoma for multiseptated cystic hepatic lesions with papillary projection on computed tomography (CT) and magnetic resonance imaging (MRI). Here we report the case of a 47-year-old woman with several months of postprandial discomfort and abdominal fullness. CT and MRI revealed multiseptated cystic lesions with papillary excrescences. A left hemihepatectomy was performed. Histology showed a benign mucinous cystic tumor with ovarian-like stroma.

Hemorrhagic fever with renal syndrome (HIFRS), scrub typhus, murine typhus and leptospirosis have been the principal acute febrile diseases in Korea. To evaluate the seroepidemiologic patterns of acute febrile illness, sera collected from 2,423 patients in 1996 were examined for antibodies against Hantaan virus, Orientia tsutsugamushi, Rickettsia typhi, and Borrelia burgdorferi by indirect immunofluorescent antibody technique (IFA) and macroscopic agglutination test for Leptospira interogans. Seropositive cases against O. tsutsugamushi, Rickettsia typhi, Leptispira interogans and Hantaan virus were 192 (7.9%), 193 (8.0%), 12 (0.5%) and 324 (13.4%), respectively. Male was more affected in HFRS and murine typhus contrasting to scrub typhus and leptospirosis in female. Most positive cases occurred during October and November for scrub typhus, and during November and December for HFRS. These results showed similar patterns with previous epidemical data for recent couple of years, and possibly implied no significant changes occurred in ecologic situations for acute febrile diseases in Korea.

We investigated the role of the tumor suppressor genes in the germ cell tumor. Immunohistochemistry (IHC) and polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) for p53 mutation were done in 46 cases of the germ cell tumor with paraffin embedded tissue. The immunohistochemical staining for Rb protein was also performed in the same specimens. The following results were obtained. The overexpression of the p53 protein was detected in 7 of 46 cases (15%). p53 mutation by PCR-SSCP was detected in 1 of 46 cases (2.2%). Expression of Rb protein was negative in 19 cases (41%). These results suggest that p53 mutation does not play an important role in the initiation and progression of germ cell tumors.

PURPOSE: The purpose of this study was to measure the level of job stress and health status and find out factors affecting the health status among circulation enterprise workers. METHOD: This study was a cross-sectional descriptive study. The subjects were 128 workers whose mean age was 33.2 years. Korean occupational stress questionnaire Short Form was used to measure job stress. Todai Heath Index that was made by Aoki in 1977 and translated by Kim(1997) was used to measure the health status. RESULTS: The total job stress scores of men and woman fell in the lower 50% of Korean workers. Job autonomy and interpersonal conflicts as a subcategories fell in upper level 50% in both men and women and job insecurity fell in the upper level 50% in women. The mean score of health status was 51.47, indicating slightly higher frequency of complains of health symptoms. There was no significant correlation between total job stress and total health status. Finally, factors influencing the health status were organizational system and age. CONCLUSION: Based on the results of this study, it is necessary to develop comprehensive stress management programs including interventions of personal and organizational levels for promoting workers' health.

PURPOSE: This study was done to explore the rates and methods of contraception among Korean adolescents from 2007 to 2009. METHODS: The study was a descriptive study. The data were taken from a web-based survey on risk behavior of Korean youth that was conducted between 2007 and 2009 by the Korea Centers for Disease Control and Prevention. RESULTS: Among adolescents, 4.7% in 2007, 4.6% in 2008, and 4.7% in 2009 reported having had sexual intercourse. In those who had sexual experiences, less than 30% reported consistent use of contraception, whereas more than 45% report no contraceptive use at all. A condom was the most frequently used contraceptive method and its use has increased continuously among contraceptive users. Some of the adolescents were, nevertheless, using unreliable methods such as withdrawal or the rhythm method. CONCLUSION: The results of this study indicate that most adolescents are not using contraception consistently and some were relying on unreliable contraceptive methods. Efforts to raise awareness about consistent and correct contraceptive use and the importance of dual protection are essential.
