LASIK is an effective and exact procedure to correct myopic refractive error but fatal complication may be happened during making corneal flap using microkeratome. We report a patient who developed acute central stomal melting following LASIK on postoperative day 4. This complication was treated by lifting the flap and scraping the interface of corneal flap & central stroma with a metal blade. After 4 months, overcorrected hyperopic refractive error was retreated with excimer laser ablation and patient recovered successful visual acuity. The pathogenesis of this case is not completely understood. Corneal endothelium and central cornea stroma may be mechanically damaged due to excessive suction ring application during LASIK procedure. Interface epithelial ingrowth may be associated with early postoperative inflammation and infection of corneal flap may produce proteinase which melts corneal flap. If corneal flap melting happens after LASIK procedure, early surgical debridement of melting stroma and proper reattachment of the flap may be needed.

The diagnosis and treatment of avascular necrosis of femoral head advanced, after Freud issued examples of bilateral avascular necrosis of femoral head (AVN) in 1926. But still not fixed in treatment and diagnosis. Recently early diagnosis and treatment produced good result. Whole body bone scan, intraosseous pressure mornitoring, intramedullary venography, C-T, or MRI, Selective femoral angiography also used in early diagnosis. Selective femoral angiography was performed for 56 patients, who has suspected as AVN by sumple X-ray and WBBS in order to estimate. How the femoral angiographic finding exist in AVN. In the control group femoral angiography performed to 5 person with normal stage of clinical and radiologic finding. So the result are as following l. All cases in the control group were not observed terminal branch of superior and inferior capslar branch. 2. In AVN the alteration of vasculature appeared 22 patients among 56 patient. 3. The altered vasculature presented 87.5% in traumatic group and 31.5% in nontraumatic group. 4. Collateral circulation was 22.2% in the cases of patients under 6 moths of the time interual between etiological events and clinical symptoms, 89.5% over 6 months. 5. Collateral circulation received 86.8% from inferior gluteal artery two cases from superior gluteal artery, and three cases form obturator artery. 6. Clinical tolerance was supposed to in well developed collateral circulation. According to the above results, Vascular alteraion were noted very much in traumatic group and development of collateral circulation were related promote clinical tolerance. Selective femoral angiography was not effective to assist early diagnosis and treatment of AVN for it could not detect terminal branch of superior and inferior capsular artery that reflected intraossous vasculsture. We need the new nethod of angoigraphy in order to early diagnosis.

Although cystic teratoma is the most common benign tumor of the ovary, the association of sebaceous gland tumor with cystic teratoma is rare. We have recently experienced a case of sebaceous gland tumor, arising in the cystic teratoma of the ovary in a 78-year-old Korean woman. Histologically, the tumor was characterized by an organoid lobular architectures of the sebaceous glands which are exculsively composed of germinative and mature sebaceous cells. Although it is difficult to come to a valid conclusion due to the presence of atypical mitosis and necrosis, this tumor was regarded as benign from the viewpoint of preserved organoid structures, and absence of capsular invasion or metastasis.

BACKGROUND: Recent studies have shown an incomplete agreement with the previously proposed diagnostic criteria of Hanifin and Rajka for atopic dermatitis(AD). This could be due to ethnic differences in the clinical manifestations of AD. To make a diagnosis of AD with confidence, one has to depend on the history and clinical picture according to race. OBJECTIVES: The purpose of the present study was to find out the importance of individual symptoms and histories for the diagnosis of Korean AD by questionnaire. METHODS: The frequency of 25 questionnaire items was studied in 130 patients with typical AD (48 childhood, 82 adolescence/adult) compared to that in 198 control subjects (89 childhood, 109 adolescence/adult). RESULTS: Nine items(itchy with bodily heat, itchy when sweating, cholinergic urticaria, miliaria, irritation with fabrics, food reaction, pollen allergy, itch with stress) were shown to be of much diagnostic significance(p<0.001) in childhood AD,otherwise thirteen items(itchy with bodily heat, itchy when sweating, cholinergic urticaria, sense of fever, excessive sweating, miliaria, irritation with cosmetics, irritation with fabrics, irritation prone hands, itchy with woolen clothes, pollen allergy, itch with stress, dermographism) were in adolescent and adult, AD. CONCLUSION: We found some diagnostic significance of clinical histories in Korean AD patients by questionnaire. We propose that this accessible questionnaire would be an efficient and powerful method with which to obtain new and valid information on AD.

Echocardiography was done with Ekoline 20 model of Smith Kline Instrument in 91 patients of mitral valvular heart disease, 46 with mitral stenosis, 10 with mitral insufficiency, 38 with mitral stenoinsufficinency and 115 normal controls. The results obtained are as follows. 1. Right ventricular dimension was 13.61+/-5.61 mm/sq m. in normal controls, 16.50+/-5.06mm/sq m. in mitral stenosis, 20.17+/-3.28mm/sq m. in mitral insufficiency, 18.61+/-8.48mm/sq m. in mitral stenoinsufficiency revealing significant increment in all mitral valvular disease groups but there was no significant difference btw. each disease groups. 2. Left ventricular end-diastolic dimensions was 29.83+/-7.06mm/sq m. in normal controls, 41.57+/-7.77mm/sq m. in mitral insufficinency, 38.48+/-10.22mm/sq m. in mitral stenoinsufficiency revealing significant increment but there was no significant difference btw. mitral stenosis and normal controls. 3. Left atrial dimension was 17.57+/-4.96mm/sq m. in normal controls, 33.22+/-5.32mm/sq m. in mitral stenosis, 35.96+/-7.35mm/sq m. in mitral insufficiency, 35.00+/-8.22 in mitral stenoinsufficiency revealing significnat increment in whole mitral valvular disease. 4. E-F slope was 90.76+/-30.20mm/sec in normal controls 18.08+/-10.3mm/sec in mitral stenosis, 29.52+/-19.3mm/sec in mitral stenoinsufficiency revealing marked decrement. In mitral insufficiency, it was 65.3+/-45.4mm/sec revealing significant decrement but not so severe as previous. 5. There was no significant difference between normal controls and mitral valvular disease in valve excursion. 6. Left atrial dimension to aortic root size was 1.13+/-0.31 in normal controls, 1.77+/-0.63 in mitral stenosis, 1.56+/-0.60 in mitral regurgitation and 1.82+/-0.56 in mitral stenoinsufficinecy revealing significant increment in whole mitral valvular heart disease.
