Trichoepithelioma. so named by Jarisch(1894), is a rare benign neoplasm of the skin on face and eyelid. The solitary type which is the most usual form seen in the eyelid occurs mainly in adult, on the other hand multiple type begin to appear at adolescence or puberty as a dominantly inherited condition. A 21 year-old korean female was found to have trichoepithelioma in her left lower eyelid mangm.

Pseudomonas aeruginosa is the most common and the most severe Gram-negative corneal pathogen. Pseudomonas keratitis often arises from the use of a contaminated fluorescein solution or from contaminated medications used either to examine or to treat a corneal abrasion or injury. Pseudomonas keratitis is an acute rapidly progressive corneal ulcer with greenish pus and hypopyon. A 49 year old Korean woman was found to have pseudomonas keratitis whose clinical features. were different from the classic pattern of pseudomonas keratitis.

BACKGROUND/AIMS: The purpose of this study was to estimate the prevalence of Barrett's esophagus (BE) and its association with reflux esophagitis (RE) and peptic ulcer disease detected by free charge endoscopy which was covered by the National Health Insurance at a secondary care hospital, and to compare the results of the biopsy of BE with that of cardiac intestinal metaplasia (CIM). METHODS: A total of 4,002 patients underwent endoscopy from March 2010 to December 2012. BE was diagnosed if there was histologically proven specialized intestinal metaplasia, and CIM was diagnosed if intestinal metaplasia was accompanied with chronic gastritis. RESULTS: Four hundred twenty four patients underwent endoscopic biopsy, and the prevalence of BE was 1.0% (42/4,002). The mean age and the proportion of males in BE were significantly higher than those of the rest of study population, and BE had slight tendency related to RE than the rest of study population. CIM was observed in 34 patients and BE and CIM showed similar results, regarding age, sex and association with RE. The mean length of endoscopic Barrett's mucosa of BE group was 9.2+/-5.1 mm, and it was similar to that of CIM. CONCLUSIONS: The prevalence of BE in the secondary care hospital was not low, and old age and male sex were significantly associated with BE. Because BE was observed in about 10% of biopsied patients and CIM was observed in a similar percentage with BE, the precise targeted biopsy is warranted and the biopsy method should be reestablished through the large prospective study of multiple secondary care hospitals.

The objective of the present study was to evaluate the hemodynamic characteristics of an atherosclerosis-prone coronary artery compared to the aorta. We describe three- dimensional spatial patterns of wall shear stress (WSS) according to the impedance phase angle in pulsatile coronary and aorta models using in vivo hemodynamic parameters and computed numerical simulations both qualitatively and quantitatively. Angiography of coronary arteries and aortas were done to obtain a standard model of vascular geometry. Simultaneously to the physiologic studies, flow-velocity and pressure profiles from in vivo data of the intravascular Doppler and pressure wire studies allowed us to include in vitro numerical simulations. Hemodynamic variables, such as flow-velocity, pressure and WSS in the coronary and aorta models were calculated taking into account the effects of vessel compliance and phase angle between pressure and flow waveforms. We found that there were spatial fluctuations of WSS and in the recirculation areas at the curved outer wall surface of the coronary artery. The mean WSS of the calculated negative phase angle increased in the coronary artery model over that in the aorta model and the phase angle effect was most prominent on the calculated amplitude of WSS of the coronary artery. This study suggests that the rheologic property of coronary circulation, such as the fluctuation of WSS/WSR induces several hemodynamic characteristics. A separation of flow-velocity, a difference in phase between pressure conductance and blood flow and prominent temporal and/or spatial oscillatory fluctuations of the shear forces as a function of pulsatile flow might be important factors in atherogenesis and progression of atherosclerosis.

OBJECTIVE: To explore the incidence of fragile X premutation in patients with idiopathic premature ovarian failure, particularly in the Korean population. DESIGN: A prospective study. MATERIALS AND METHODS: Eighty-three women affected by idiopathic premature ovarian failure were recruited for this study. Patient with known causes of premature ovarian failure were excluded: cytogenetic abnormalities, prior chemotherapy, prior bilateral oophorectomy. DNA was extracted from peripheral blood. Fragile X (FRAXA) premutation was evaluated by PCR amplification of and Southern blot analysis for FMR1 gene. RESULTS: The FRAXA premutation was detected in three (3.6%) out of 83 patients with idiopathic premature ovarian failure. CONCLUSION: This result suggests that fragile X premutation screening is indicated in patients with idiopathic premature ovarian failure, particularly in the Korean population.
