Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.

By implementing epoch-making policies for industrial promotion, the national economy has made a remarkable development. As a result of such economic growth, industrial accidents and occupational diseases have become a serious problem in Korean society. In the presidential order for the execution of the Korean Labor Standard Law, neuritis and other diseases stemming from health impairments due to vibrations in industrial processes are designated to be dealt with as vibration diseases. In the case of vibration disease, industrial accident compensation is not effectively paid. In order to investigate the vibration hazards of rock-drill operation, the authors studied the subjective symptoms and performed physical function tests on a total of 79 persons (vibration exposed group) who used rock-drills, and 39 persons (control group) who did not use rock-drills at anthracite mines. The results of the physical function test were as follows : 1. The right hand was more affected by white finger than the left hand. 2. Independent variables such as duration of rock-drill operation, age, drinking and smoking were identified as statistically significant factors for the occurrence of white finger. 3. In the pain sense threshold, the group with Raynaud's phenomenon showed a statistically higher level than that of the control group. 4. The skin temperature of the group with Raynaud's phenomenon was lower than that of the control group. The recovery time of skin temperature after cooling was delayed compared with the value of the control group.

We conducted a retrospective study of 20 penetrating keratoplasty (19patients) for corneal opacity due to herpes simplex keratitis from January 1992 to February 1997 at National Medical Center. We exaniined f requeuey of graft rejection and recurrence of herpetic keratitis after penetrating keratoplasty. The patients were grouped into control & treatinent, group according to the use of antivirial drug after penetrating keratoplasty and we examined the difference in rate of recurrence between two groups. The follow-up period was from 8 months to 68 months, mean follow-up period being 29.6 months. Graft rejection was seen in 3 eyes out of 20 eyes (15.0%) and recurrence was developed 3 eyes out of 20 eyes (15.0%). Recurrent herpetic keratitis developed in 15.4%(2 of 13) of the eyes in control group and 14.3% (1 of 7) of the eyes in treatment group. There was no statistically significant difference in recurrence rate between two groups (p)0.05). Postoperative prophylactic antiviral treatment is not associated with decreased rate of herpes simplex keratitis recurrence.

The authors have evaluated the effect of topically applied 1% cyclosporine A for four weeks after limbal allograft transplantation for ocular surface stability in severely ocular surface damaged rabbits. A total eleven severely damaged rabbits were subdivided into three groups of four limbal autograft (AUTO), three limbal allograft (ALLO), four limbal allograft with topical application of 1% cyclosporine A five times daily for four weeks (ALLO-C). We examined ocular surface smoothness, clarity, corneal vascularization before surgery and three months after surgery, and classified three grade (success, partial success, failure) according to result. In AUTO, three eyes were success, one eye was failure. In ALLO, one eye showed inferior graft detachment and one eye was success, two eyes were failire. In ALLO-C, no graft detachment detected and one eye was success, two eyes were partial success, one eye was failure. We knew that. ALLO-C show more effective ocular surface stability than ALLO. These result suggest ALLO-C can be used as alternative treatment of AUTO in ocular surface reconstruction. But, rnore study for duration and concentration of cyclosporin A will be need.

We have reported general principles of low vision aid prescription. But, we have not reported near vision aid prescription only. So, we analyse prescriptions of near low vision aid(diagnosis, type, magnification, etc) and present new near low vision aids that patients feels comfortable. We reviewed the clinical records of 100 patients who visited our low vision clinic more than twice and was prescribed near low vision aid for low vision. According to the data analysed, optic nerve atrophy was the most common etiology for low vision. Illuminated hand held magnifier(31.3%), telemicroscope with plus cap(27.7%), aspheric doublet sens(Clear Image II)(24.1%) were low vision aids most commonly used for near vision, but we knew new trend that newly prescribed aids(telemicroscope with plus cap, aspheric doublet lens) were prescribed more than illuminated hand held magnifier. After prescription of the low vision aid, visual acuity improved significantly (p<0.05). We examined contrast sensitivity test to measure the functional acuity and predict the visual prognosis after prescription of low visio aid.In addition,we studied the relationship between reading speed and the degree of contrast sensitivity and we knew that the relationship between degree of contrast sensitivity and reading speed was associated(p<0.05). Majority of patients(89%) were benefited from prescribed low vision aids.
