To examine prospectively the efficacy and reliability of excimer laser photorefractive keratectomy for myopia. we treated 147 eyes of 86 patients with a VisX Twenty/Twenty excimer laser and followed them up for 1 year and follow up 48 eyes of 26 patients for 2 years. The patients were divided into two groups with preoperative myopia: group 1 with diopters between -1.50 and -6.00, group 2 with diopters between -6.01 and -10.00. At 1 year, the group 1 with a mean preoperative refractive error of -4.61D changed to -0.40D, the group 2 changed from -7.50D to -0.92D. At 2 years, the group 1 with a mean preoperative refractive error of -4.28D changed to -0.41D, the group 2 changed from -7.75D to -1.04D. At 1 yera, in group 1, 90.91% (70 of 77) of eyes and in group 2, 64.29%(45 of 70) of eyes were corrected within 1D of intended refraction,respectively. At 1 years, in group 1, 94.81% (73 of 77) of eyes and in group 2, 84.29%(59 of 70) of eyes achieved an uncorrected visual acuity of 0.5 or better. And at 2 years, in group 1, 81.82% (18 of 22)of eyes, and in group 2, 50.00% (13 of 26) of eyes were corrected within 1D of intended refraction, respectively. At 2 years, in group 1, 95.50% (21% of 22) of eyes and in group 2, 84.62%(22 of 26) of eyes achieved an uncorrected visual acuity of 0.5 or better.

Hearing loss is a very common health problem throughout the world, although the number of hearing impaired individuals varies greatly in the countries. It is generally accepted that hearing impairment inevitably leads to a breakdown in communication and physical and mental health problems consequently. Nevertheless, few community based studies have been undertaken to examine both the mental and more general physical state of the hearing impaired patients. This study was conducted to evaluate the anxiety and depression in hearing impaired patients. Self-administered questionnaires including sociodemographic data were given to 336 subjects over the age of 18 years who visited the Health Management Center, Uijongbu St. Mary's Hospital for the routine health check up from January 1996 to April 1996 and three hundred seventeen samples (male: 197, female: 120) were selected. For the assessment of anxiety and depression we used Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) devised by Zung. And hearing impairment was evaluated using a Beltone Model 110 Audiometer. The results were statistically analyzed by ANOVA test and x(2) test. The results obtained were as follow: 1. The mean anxiety scores counted by SAS of 0-15dB HL (hearing loss) group (classified by the average loss in the better ear at 500, 1,000, 2,000Hz frequencies), 16-29dB HL group, 30-44dB HL group, more than 45dB HL group were 33.1+/-6.6 32.2+/-5.9, 41. +/-8.4, 42.8+/-6.0 respectively. And the mean depression Scores counted by SDS of 0-15dB HL group, 16-29dB HL group, 30-44dB HL group, more than 45dB HL group were 37.4+/-7.7, 37.2+/-7.2, 46.2+/-8.4, 48.6+/-8.6, respectively. The more than 30dB HL group showed significant high scores in SAS and SDS than the less than 30dB HL group (p<0.001). 2. The frequency of clinically significant anxiety disorder (SAS > or = 50) was 3.4% in less than 30dB HL group and 11. 1% in more than 30dB HL group. The difference between two groups was statistically significant (p<0.05). 3. The frequency of clinically significant depression disorder (SDS > or = 50) was 5.1% in less than 30dB HL group and 39.5% in more than 30dB HL group. The difference between two groups was statistically significant (p<0.05). 4. When several important interaction variables related to anxiety: and depression (such as age, sex, marital status, education level, economic status, occupation, religion) were stratified and we compared the groups between the more than 30dB HL and less than 30dB HL, most factors about anxiety and depression showed the significant differences in two groups. 5. Multiple logistic regression analysis revealed that hearing loss(p<0.05) predicted anxiety disorder (SAS> or = 50) and hearing loss(p<0.01), age(p<0.05) predicted depression disorder (SDS> or = 50). In conclusion, there was significant difference in anxiety and depression scores, between more than 30dB HL(in the better hearing ear) group and less than 30dB HL group. This study suggested that anxiety and depression should be considered as adverse effects of hearing impairment.

Actinomycosis, in which the principal causative agent in man is known to Actinomyces israelii, is a chronic, suppurative diseases characterized by extensive fibrosis, multiple abscesses, and formation of sinus tracts that drain suppurative exudates. On the basis of the anatomical sites involved; it can be subclassified into the cervicofacial form, which is the most common form, pulmonary form and abdominal form. Kidneys are rarely affected. Clinically, radiologically, and at operation it is difficult to differentiate the renal actinomycosis from renal tuberculosis and renal carcinoma. The prognosis is excellent after nephrectomy followed by appropriate antibiotic therapy. We presented a case of renal actinomycosis with a brief review of the literatures.

PURPOSE: To evaluate the radiologic manifestations of the rectal leiomyosarcoma. MATERIALS AND METHODS: We reviewed CT and barium study of 2 cases of rectal leiomyosarcoma, which were operated and pathologically proved. RESULTS: In both cases colon studies showed a huge smooth marginated filling defect in the rectum. Precontrast CT scans showed a well-circumscribed, slightly Iobulated, inhomogeneous mass without calcification. Postcontrast scans showed minimal enhancement with internal low-density areas. In pathologic specimens there were large areas of necrosis and hemorrhage in the masses. Pericolic fat infiltration, lymph node metastasis, or distant metastasis were not detected. CONCLUSION: Leiomyosarcoma is rarely developed in the rectum, but general radiologic findings are similar to that of other part of the gastrointestinal tracts except for the tendency of intraluminal growth due to narrow pelvic space.

Infantile fibrosarcoma is a rare malignant soft tissue tumor occurring especially in newborn and young children under 2 years. We experienced three cases of infantile fibrosarcoma presenting in the neonatal period. Case 1 presented with a multiseptated cystic mass on his left thigh at birth that was diagnosed as lymphangioma. After picibanil injection, we noted the size of the mass doubled and a solid lesion was prominent in the magnetic resonance image. Case 2 was found to have a reddish mass on his lower back mimicking hemangioma. Over 2 weeks, the mass grew rapidly with internal hemorrhaging. Case 3 was noted to have an encircling mass around the splenic flexure, which developed into congenital bowel obstruction. All of the tumors were resected completely, but microscopic resection margin was not clear in two patients. The two patients received adjuvant chemotherapy and all patients are well without evidence of recurrence.

An epidemiological study on brugian filariasis was carried out in endemic areas including Cheju Island in Korea, with a brief review of literatures.The results showed that the incidence among residents has remarkably decreased in Cheju Island, which was the main endemic area. Reviewing available informations on the prevalence of filariasis reported in recent years and also judging from the present socio-economic conditions which enable people to practice personal protection against mosquitos, it can be said with confidence that filariasis has almost disappeared from Cheju Island and inland areas. The disease is considered to remain at a low level of endemicity in Hugsan Islands. Certainly mass diethylcarbamazine (DEC) treatment carried out in Cheju Island in the 1960s and 1970s and remarkable economic growth followed by improved living standard and altered life-style of inhabitants could all have combined effects on the disappearance of this mosquito-borne diseae in this island. If the present trends go on, the possibility of resurgence of filariasis in Cheju Island is hardly postulated.

Lately the incidences of the patella fracture have been increasing due to frequent traffic and industrial accident, popularity of sports activity and falling. Sixty-nine cases of patella fractures, which were treated at Department of Orthopedic Surgery, Hallym College in the years of 1980 to 1985, were reviewed and the authors obtained the following results : 1. Frequently involved were third to fifth decades. 2. Traffic accident was the most common cause of the fracture. 3. Out of 69 cases, 42 were treated by open reduction and internal fixation. Among them we used circumferential wiring for 22 cases, modified tension band wiring for 13 cases and tension band wiring for 7 cases respectively. The remaining 5 cases were treated by patellectomy. 4. The most favorable recovery from the fracture was obtsined from modified-tension-band-wiring group.

In hypertensive patients it is very important to detect renal artery stenosis or pheochromocytoma, since both diseases are curable causes of hypertension. However, renal artery stenosis can be induced by pheochromocytoma, when the diagnosis of the two simultaneous disease is very difficult. We experienced two cases of pheochromocytoma presented as renal artery stenosis. Pheochromcytoma was overlooked when renovascular hypertension was diagnosed. Pheochromocytoma was found during surgery in one patient and after angioplasty in the other. In both cases, BP returned to normal after surgical removal of pheochromocytoma without repair of the stenosis. Prevention of ineffective and unnecessary renal artery angioplasty of surgery requires knowledge of this unusal association between pheochromocytoma and renal artery stenosis and a high degree of clinical alertness for pheochromocytoma.
