BACKGROUND: ST segment elevation in patient with chest pain was seen in acute myocardial infarction and in numerous other non-infarction syndrome. The causes of non-infarction syndrome were left ventricular hypertrophy, BER(benign early repolarization), and left bundle branch block in cardiac origin and were hyperkalemia and hyperventilation syndrome in metabolic origin and were others. Furthermore, the differentiation of electrocardiogram between acute myocardial infarction and non-infarction syndrome was very difficult. So, we compared and analysed characteristics of ST segment elevation of acute myocardial infarction and non-infarction syndrome that suggested the clue of early diagnosis of coronary artery disease. METHOD AND MATERIALS: We retrospectively reviewed the electrocardiogram of 961 patients with chest pain who visited the emergency center from January 1999 to December 1999. Acute myocardial infarction was diagnosed by clinical finding, electrocardiogram, cardiac enzyme, echocardiogram, and myocardial spect. Left ventricular hypertrophy, BER, and left bundle branch block in cardiac origin of non-infarction syndrome were diagnosed by electrocardiographic criteria suggested by William J. Brady. Acute myocarditis, acute pericarditis, and hyperventilation syndrome were diagnosed by clinical finding. RESULTS: Among 961 patients with chest pain, 236(24.6%) patients manifested ST segment elevation who were diagnosed acute myocardial infarction in 162(68.6%) patients and non-infarction syndrome in 74(31.4%) patients. The causes of non-infarction syndrome in 74 patients were left ventricular hypertrophy(32:13.6%), BER(28:11.9%), left bundle branch block(11:4.7%), and others(3:1.3%). Three others were acute myocarditis, acute pericarditis, and hyperventilation syndrome. Electrocardiographic characteristics of ST segment elevation of non-infarction syndrome manifested almost same finding compared to William J. Brady' criteria. CONCLUSION: ST segment elevation in patient with chest with chest pain visited emergency department was seen in acute myocardial infarction(68.6%) and the other non-infarction syndromes(31.4%). Significant number of patients were not associated with acute myocardial infarction. Therefore, we must completely understand characteristics of ST segment elevation in acute myocardial infarction and the other non-infarction syndromes to diagnose fatal early coronary artery disease and to avoid unnecessary thrombolytic therapy.

PURPOSE: To report a case of a patient who underwent penetrating keratoplasty due to acute hydrops six years after undergoing a bilateral LASIK procedure. METHODS: A 19-year old male patient with -2.75 diopter myopia received a bilateral LASIK operation at a local clinic. Forty-seven months later, -2.00 cyl axis 130o astigmatism was induced in his left eye and additional surgery was performed to correct the LASIK-induced astigmatism. The patient was referred to our hospital 16 months after the secondary operation due to reduced visual acuity in his left eye. He was diagnosed with keratectasia and acute hydrops, and penetrating keratoplasty was performed. RESULTS: The retrospective analysis of the corneal topography prior to the LASIK surgery revealed that the inferior minus superior(I-S) value was 1.25 in the right eye and 1.3 in the left eye. At the time of the first evaluation at out hospital, a slit lamp examination showed an approximate 8 x 7.5mm sized area filled with aqueous humor between the corneal flap and residual stroma, and Descemet's membrane rupture was observed. Furthermore, the histopathological section of the patient's cornea confirmed keratocytes with myxoid degeneration and edematous change. CONCLUSIONS: In young patient, particularly those with suspicious asymptomatic keratoconus, LASIK and further enhancement surgery afterwards should be considered and approached in a cautious and deliberate manner.

BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

BACKGROUND: Recruitment and development of multiple follicles in response to gonadotropin stimulation are the key factors leading to successful treatment by assisted reproductive technologies. Prediction of ovarian responses prior to stimulation is useful in counselling and helpful in adjusting the dosage of gonadotropin to individual patients. OBJECTIVE: To evaluate the number of antral follicles of both ovaries as a predictor of outcome of assisted reproductive technologies. METHODS: Data were collected by a retrospective analysis. A total of 56 consecutive infertile women were undergoing the first cycle using a standard regimen of ovarian stimulation from July, 2000 to June, 2001. Basal FSH, LH, prolactin, and estradiol concentration were measured. The number of follicles (2-5 mm) were recorded. RESULTS: In women with fewer antral follicles, the number of retrieved eggs was significantly decreased and increased the duration and dosage of human menopausal gonadotropin, but pregnancy rate was similar to those with a higher number of antral follicles. CONCLUSION: It is suggested that the total antral follicle number is sensitive ultrasound parameter in predicting the ovarian response.

Mesenteric fibromatosis is a rare nonmetastasizing fi brous tumor, characterized by fibroblastic proliferation without evidence of inflammatory response or definite neoplasia. It appears at any age, but mainly in the second to fifth decades as incidence of two to four desmoid tu mor cases per 1 million people per annum. It is pseudoen capsulated and locally invasive and has a tendency to recur, but metastases are rare. It is more frequent with Gardner's syndrome(adenomatosis coli) in which 50% of them will appear as mesenteric fibromatosis. Trauma, especially that of previous surgery, has been associated with the subsequent development of desmoid tumor. The treatment of choice is a wide margin resection of the tumor. we experienced a case of mesenteric fibromatosis without Gardner's syndrome 2 years after appendectomy in a 31-year old man and recurred at 21 months after resection and report with a review of literatures. 6

Corneal and conjunctival squamous epithelial cells have been known to express the mucin MUC1. We attempted to reveal the expression and localizational characteristics of the membrane-spanning mucin MUC1 as a component of the mucous layer in the human corneal epithelium. An antibody to the MUC1 was used to detect the MUC1 on the corneal epithelium by immunohistochemistry and immunofluorescent staining. In situ hybridization was performed to determine the distribution of MUC1 mRNA in the ocular surface. Immunohistochemically, the MUC1 mucin was observed along the apical membranes of the corneal epithelium. According to immunofluorescent staining, cells varied in the amount of mucin MUC1. Expression of MUC1 mRNA was observed in all layers of the corneal epithelium. The MUC1 mucin synthesized by the corneal epithelia exists on the apical membrane of the superficial cells. The amount of MUC1 may vary with the vertical migration and the activity of the cells.

In vitro ethylene-diamine-tetra-acetic acid (EDTA) dependent satellitism and phagocytosis of platelets by neutrophils have been considered to be rare phenomena. It is associated with pseudothrombocytopenia, abnormal histogram of platelets and pseudoleukocytosis on complete blood cell count (CBC) by automated blood cell counter, but these findings are not found in heparinized or sodium citrated blood. It has no clinical significance such as bleeding tendency or abnormal platelet function. EDTA dependent platelet satellitosis and phagocytosis must be differentiated from true thrombocytopenia. We report a case of EDTA dependent platelet phagocytosis by neutrophils in a 68 year-old male patient who was diagnosed as mycosis fungoides. His EDTA blood smear showed frequent phagocytosis of platelets by neutrophils and occasional platelet satellitism. The bood cell counts were within normal limits without pseudothrombocytopenia. Phagocytized platelets were confirmed by immunohistochemistry using GpIIb/IIIa antibody and transmission electron micrographs.

PURPOSE: To determine whether insulin-like growth factor (IGF-1) affects transforming growth factor (TGF-beta)- mediated fibronectin accumulation in human lens epithelial cell line (HLE B-3) cells. MATERIALS AND METHODS: HLE B-3 cells were incubated for 24 hours with TGF-beta (10ng/ mL), IGF-1 (10ng/mL), or both. Expression of the fibronectin gene was determined using a real-time reverse transcriptase-polymerase chain reaction (RT-PCR). Fibronectin levels were examined using western blot analysis and immunofluorescence staining. RESULTS: Expression of the fibronectin gene was not different between the TGF-beta/IGF-1 treated group and the TGF-beta treated group (p= 0.116). However, western blot analysis demonstrated decreased fibronectin levels in human lens epithelial cells treated with TGF-beta and IGF-1 compared to those treated with TGF-beta only (p < 0.01). Immunofluorescence staining disclosed inhibition of TGF-beta-induced fibronectin in the presence of IGF-1. CONCLUSION: This study suggests that IGF-1 counteracts TGF-beta-mediated fibronectin accumulation in human lens epithelial cells.

Jimson weed, also known as Datura stramonium, is a member of the Solanaceae family. Jimson weed was used by American Indians for medicinal and religious purposes. All parts of the Jimson weed plant are poisons, containing the alkaloids atropine, hyoscyamine and scopolamine. So, it is caused by these components to make a anticholinergic toxicity within 6h after ingestion. Initial manifestations include dry mucus membrane, blurred, vision, thirst, difficulty swallowing and speaking, and photophobia, and may be followed by hyperthermia, confusion, agitation, combative behavior, hallucination, urinary retention, seizure and coma. We experienced two patients who developed combative behavior and agitation with pupil dilation caused by Jimson weed. They discharged with improvement after supportive for 2days.

OBJECTIVES: Socioeconomic status plays an important role in health care and disease prevention. This study aimed to examine the association between socioeconomic status, measured by education levels and household income, and gastric cancer screening. METHODS: A total of 21,220 community-dwelling adults aged 40 to 69 years within a defined geographic area participated in a community health survey in 2009 and 2010. The survey was conducted using a structured questionnaire by trained investigators who visited the subjects' households directly. Logistic regression analysis was used to determine the relationship between self-reported participation in gastric cancer screening and socioeconomic variables (education and household income). RESULTS: The gastric cancer screening rate was 52.1% for subjects in their forties, 63.7% for those in their fifties, and 67.3% for those in their sixties. In multivariate analysis, higher education and income levels were associated with higher rates of gastric cancer screening (high school vs. elementary school: odds ratio [OR] 1.41, 95 % confidence interval [CI] 1.26-1.58; highest income quartile vs. lowest income quartile: OR 1.62, 95% CI 1.44-1.84). The gradient between income and screening rate was more pronounced in the population aged 40 to 49 years than in the other age groups. CONCLUSIONS: This study demonstrates that lower socioeconomic status is associated with decreased participation in gastric cancer screening. Our findings suggest that the screening program should be focused on low-income and less-educated populations, especially among younger adults, to reduce health disparities.
