BACKGROUND: Not rarely we can find young people with acute myocardial infarction(AMI), many studies revealed they have fewer risk factors and less severe coronary angiographic abnormalities than middle and old aged group. METHODS: We studied clinical characteristics and coronary angiographic findings of 5 young men with AMI treated at Masan Koryo General Hospital from June 1986 June 1992. RESULTS: The age ranged between 19 and 32 years(mean 25.4). They had no other risk factors except cigrarette smoking(4 out of 5). Their coronary angiograms revealed no significant lesion in each infarct related artery. After discharge, all patient remained asymptomatic. CONCLUSION: AMI in young man might be related with cigarette smoking, and coronary artery spasm and/or thrombosis may play a significant role in its pathogenesis.

This study evaluates the suitability of cadavers embalmed by the ethanol-glycerin fixative for the dissection course of medical students and the hands-on dissection workshop of clinicians. Five cadavers were embalmed by two different methods: two formalin-phenol fixation (FPF) and three ethanol-glycerin fixation (EGF) cadavers. The measurement of physical and chemical characteristics including ranges of motion (ROM), bacterial and fungal culture tests, and ultrasonography were performed for each cadaver. The EGF cadavers were evaluated to be significantly more suitable than FPF cadavers for the physical and chemical characteristics including color, texture, elasticity, wetness (softness), skin incision, vessel ligation and suture, decollement, odor, and irritant. In shoulder, elbow, and wrist joints, ROMs of the EGF cadavers were statistically more than those of the FPF except for elbow extension. On bacterial and fungal culture tests at 8 weeks after carrying out of refrigerator, one bacteria were detected in one EGF cadaver; however, some bacteria and fungi could be detected in all FPF cadavers. The ultrasound images of abdominal organ and thigh musculature could be more clearly detected in the EGF cadavers than those of FPF cadavers. These results indicate that the EGF method had a sufficient antibiotic effect and produced cadavers with flexible joints and a high tissue quality suitable for various cadaveric dissection courses.

Magnetic resonance image (MRI) is the most sensitive imaging test of the spine in routine clinical practice. Unlike conventional x-ray examinations and computed tomography scans, high-quality magnetic resonance images can be assured only if patients are able to remain perfectly still. However, some patients find it uncomfortable to remain still because of pain. In that condition, interlaminar cervical epidural injections can reduce pain and allow the procedure. When using air with the "loss of resistance" technique in epidural injections to identify the epidural space, there is the possibility of injected excessive air epidurally to mimic a herniated disc. We describe a case report of epidural air artifact in a cervical MRI after cervical epidural injections.

OBJECTIVE: Shunt-dependent chronic hydrocephalus (SDCH) is known to be a major complication associated with aneurysmal subarachnoid hemorrhage (aSAH). Old age is known to be one of numerous factors related to the development of SDCH. This study investigated whether postoperative cisternal drainage affects the incidence of SDCH and clinical outcome in elderly patients with aSAH. METHODS: Fifty-nine patients participated in this study. All patients underwent aneurysmal clipping with cisternal cerebrospinal fluid (CSF) drainage. Clinical variables relevant to the study included age, sex, location of ruptured aneurysm, CT finding and clinical state on admission, clinical outcome, and CSF drainage. We first divided patients into two groups according to age (<70 years of age and > or =70 years of age) and compared the two groups. Secondly, we analyzed variables to find factors associated with SDCH in both groups (<70 years of age and > or =70 years of age). RESULTS: Of 59 patients, SDCH was observed in 20 patients (33.9 %), who underwent shunt placement for treatment of hydrocephalus. Forty seven percent of cases of acute hydrocephalus developed SDCH. In the elderly group (> or =70 years of age), the duration and amount of CSF drainage did not affect the development of chronic hydrocephalus. CONCLUSION: In elderly patients, although the incidence of SDCH was significantly higher, clinical outcome was acceptable. The duration and the amount of cisternal drainage did not seem to be related to subsequent development of chronic hydrocephalus within elderly patients aged 70 or older.

OBJECTIVES: To predict of the survival of patients with epithelial ovarian cancer, multivariable analysis was done to identify variables with independent prognostic factors. Based on materials from 191 clinical trials performed by Department of Obstetrics and Gynecology, Hanyang University Hospital, we constructed a prognostic index (Pp with considerable predictive power for long-term survival of patients with epithelial ovatian cancer treated with cis-platin based combination chemotherapy, METHODS: On identifying variables with independent prognostic value, statistical analysis were performed with clinicopathologic variables including age, FIGO stage, histologic subtype, histologic grade, residual tumor, presence of ascites, pretreatment levels of hemoglobin, platelet, and tumor markers(CA 125, CA 19-9). We also analyzed biological variables using immunohistochemical staining for GST-pie (glutathione-s-transferase-pie), p-glycoprotein, and MT (metallothinein) as a drug resistance and uPA (urokinase type plasminogen activator), PAI-1 (plasminogen activator inhibitor-l), nm23 (nonmetastatic gene 23) as a tumor invasion and metastasis. In addition, univariable analysis was performed followed by multivariable analysis using Coxs proportional hazards model to identify variables predictive of poor prognosis. Prognostic index (PI) was calculated based on sum of individual beta-coefficient of the most important independent prognostic value. RESULTS: With univariable analysis, age, FIGO stage, histologic grade, histologic subtype, presence of ascites, residual tumor, initial value of CA 125, MT, uPA, and PAI-1 were found to predict of patients survival. In the multivariable analysis and proportional hazard model, the pretreatment characteristics needed for the calculation of the PI are the age, the site of metastases expressed as stage, the histologic subtype, the size of residual tumor, the histological grade, and the presence of ascites. In the subgroup comprising the 10% of the patients with the best prognosis, 5-year survival rate was 78.9%, whereas in the subgmup comprising the 10% with the poorest prognosis, 5-year survival rate was 7.1%, which illustrates the large variability of the prognosis among patients. CONCLUSIONS: The PI was found to retain its value after response was achieved. The information provided by the PI can be expected to be useful in treatment planning and the proper stratification of patients in clinical trials.

PURPOSE: To evaluate the usefulness of MDCT angiography in the diagnosis of vertebrobasilar artery dissection. MATERIALS AND METHODS: Between July 2003 and December 2005, 39 patients who underwent MDCT angiography and digital subtraction angiography with a history of suspicious vertebrobasilar artery dissection were selected. A blind interpretation of images was made by two observers, retrospectively. A diagnosis of dissection in MDCT angiography was made according to the following criteria: presence of an intimal flap, aneurysmal dilatation, abrupt or tapered luminal narrowing, alternatively dilated and narrowed lumen. The sensitivity and specificity of MDCT angiography in depicting vertebrobasilar artery dissection were determined. RESULTS: 43 vertebrobasilar artery dissections were diagnosed by MDCT angiography in 39 patients. The interobserver agreement was good (kappa =0.92). A diagnosis was made by the presence of an intimal flap (n=16, 36%), abrupt or tapered luminal narrowing (n=16, 36%), aneurysmal dilatation (n=13, 30%), alternatively dilated and narrow lumen (n=14, 32%). The sensitivities and specificities of MDCT angiography were 91%, 88% as determined by the first radiologist, and were 89%, 87% as determined by a second radiologist, respectively. CONCLUSION: MDCT angiography is a useful method for the diagnosis of vertebrobasilar artery dissection.

The primary malignant tumor of the peritoneum also known as primary peritoneal carcinoma or primary peritoneal papillary serous carcinoma is rare and involves the peritoneum, especially the pelvic peritoneum of female patients. It is difficult to differentiate histologically between papillary mesothelioma, primary ovarian tumor and primary peritoneal carcinoma. We report two cases of the primary peritoneal carcinoma with clinical presentation and histologic characteristics.

Twenty six cases of borderline ovarian tumor(BOT) were treated between Jan. 1985 and Dec. 1997 at the Department of Obstetrics and Gynecology, Hanyang University. The clinical records were reviewed for all patients including histopathology, clinical features, and follow-up. The frequency of BOT was 12%(26/214) of epithelial ovarian malignancies, and patients with these tumors tend to present at a younger age(36 yrs) than those with invasive carcinomas. In terms of histologic type, mucinous type(21/26: 81%) were more prevalent than serous tumor(5/21: 19%) in this study. The positive rate of CA 125 was 20% in serous, and the positive rate of CA 19-9 was 24% in mucinous tumor. The size of mucinous was larger than that of serous tumors(17.1 cm vs 9,3 cm). Almost all of these tumor categorized as early stage(stage I: 96%), however, only one patient with serous tumor had advanced stage of disease(stage III: 4%), Therefore BOT tend to be diagnosed as earlier than invasive carcinoma. About 2/3 of patients were treated as conservative surgery(unilateral salpingooophorectomy or enuclation). Postoperative adjuvant chemotherapy was not given about half of cases(13/26). Median follow-up was 43 months and recurrent case was found only one in serous tumor, All patients in this study are still alive and free of disease except one, 5-year survival rate was 100%. But large number of study and long-term follow-up are needed to make a decision to treat and manage of BOT.
