Stable angina is a chronic, systemic disease with a wide range of associated symptoms and clinical outcomes. Prompt diagnosis can be challenging for clinicians. Typical chest pain caused by stable angina occurs when the myocardium receives inadequate oxygen, resulting in myocardial ischemia. Various diagnostic tools including non-invasive tests such as coronary computed tomographic angiography and image-based stress tests have evolved over the last decade. An important factor in the selection of the proper diagnostic test for stable angina is assessment of the pre-test probability in the event of possible coronary arterial stenosis.

The changes of corneal curvatures were measured in 63 cataract cases before and 2 months after cataract extraction with the aid of ophthalmometer and photo keratoscope. The change of the cornea in the vertical curvature was shown to be greater than that of horizontal curvature, in cases of conventional large corneal incision(120-170 degrees) of cataract surgery. Vertical curvature of the cornea was decreased and horizontal curvature was increased. The corneal astigmatism before and 2 months after surgery were respectively 0.67D. and 1.56D. showing the difference of 0.89D.

BACKGROUND: Although the histologic picture of epidermolytic hyperkeratosis is diagnostic for bullous congenital ichthyosiform erythrokerma (BCIE), it is not specific for it. It is found also in several other conditions, that is, linear epidermal nevus, epidermolytic keratisis palmaris et plantaris and epidermolytic acnthoma. Among these, BCIE is caused by mutations of the defferentiation s0pecific keratins K1 and K1-. These mutations produce a weakened cytoskeleton that is prone to collapse resulting I cell fragility and lysis. But the pathogenesis of epidermal nevus showing the similar histologic feature with BCIE is not known. OBJECTIVE: The purpose of our study is to conpare the electron microscopic picture and the immunohistochemical features, and to find the possible pathogenesis of both diseases. METHODS: We evaluated the clinical, histopathologic nd electron microscopic features of 5 BCIE cases and 14 epidermal nevus cases which were histologically diagnosed with epidermolytic hyperkeratosis at the department of dermatology at Wonju Christian Hospital, Shinchon Severance Hospital and Yongdong Severance Hospital, from January 1981 to June 1994. The immunohistochemical staining(PAP method) using monoclonal antibody against cytokeratin was performed on BCIE and epidermal nevus. RESULTS: Light microscopy of both BCIE and epidermal nevus showed the same histologic changes including hyperkeratosis, increased keratohyaline granules, acanthosis and perinuclear vacuolization of upper malpighia layer. Electron mioroscopic findings in both diseases were similar. Aggregation of tonofilaments is noted in the squamous cells, but is not evident in basal cells.In immunohistochemical study of both diseases, 34betaE12 is stained in the whole epidermis and is stuonger ex0ressed in the basal layer tan suprabasal layers. LP34 staining is evident in suprabasal cell layers up to the cornified cell layer. CONCLUSION: Electron microscopy and immunohistochemical study of both diseases showed the same finding. We thind that a defect in the differentiation specific keratins, K1 and K10 is perhaps involved in epidermal nevus histologically showing epidermolytic hyperkeratosis as in BCIE.

In modem medical industries as in others, it has been emphasized by many experts such as Dr. Mayer and Dr. Donabedean that there should be quality assurance activities applying statistical knowledges in the processes of medical management and medical staff themselves for the better medical care and customer satisfaction. Three of our quality assurance programs for the purpose of shortening the treatment time In the department of emergency medicine in Keimyung University, Dong-San Medical Center had been carried out during the period of June 94 through December 95. Our methodology was mainly the process emphasized ; finding the causes of delaying factors in various processes related to the works of nurses, doctors, laboratory services, radiology services etc. in the emergency room, holding various meetings among the related groups with genuine discussions, notifying the new results in each step, encouraging the positive ones and also applying the new leadership technics. During the period of June 94 through December 95(for 1.5 years), the average E.R. patient treatment time from registrations to dispositions had been reduced by about 2 hours (from 5 hours 3 minutes to 2 hours 5 minutes) and its variations among the different specialities had been narrowed down to significant degree (p<0.05) revealing the preprogram base line standard deviation of 2.43 to 1.28 in post program through continuous quality assurance programs. It was also noted that the successful results of Q/A program have been closely related to the fact that the process should be designed and redesigned repeatly as needed and that all the participants related were actively involved in the planning and redesigning processes.
