To evaluate and compare the clinical results of implantation of the AcrySof(r) with Hydrophilic Acrylic IOLs in early postoperative period(to 2 months), we retrospectively analyzed 34patients who had taken clear cornea incision and had been implanted with AcrySof(r)IOL in one eye and Hydrophilic Acrylic IOL in the other eye. There were no stastically significant difference in postoperative best corrected visual acuity, preoperative and postopearative astigmatic changes between AcrySof(r) and Hydrophilic Acrylic IOLs. But, the rates of postoperative capsular fibrosis and contracture of Hydrophilic Acrylic IOL was higher than those of AcrySof(r) IOL as well as postoperative complications. In conclusion, in the degree and rate of after-cataract, AcrySof(r)IOLs are more useful than Hydrophilic Acrylic IOLs. ;therefore, more excellent in long term visual prognosis. Further studies will be needed for the evaluation of clinical safety and efficacy.

We performed simple and successful canalicular reconstruction with smooth tip pigtail probe in 56 cases of inferior canalicular laceration. After general anesthesia or local anesthesia in inferior and superior canthal area, upper lacrimal sac area and lacerated inferior eyelid, methylcellulose mixed fluorescein was injected through the superior canaliculus under the surgical microscope with cobalt blue filter and simply found cutting end of the inferior canalicullus. Smooth tip pigtail probe was inserted and silicone stent was connected the superior and inferior canaliculi and the peri canalicular sheath was sutured with and to end anastomosis. Silicone tube was removed after postoperative 8 weeks and 86% of the patients(48/56 cases) was successful without epiphora. Smooth tip pigtail probe, methylcellulose mixed fluorescein, silicone stent, and end to end anastomosis of pericanalicular sheath under the surgical microscope would increase the success rate of pigtail probe canalicular reconstruction.

BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

A finite element analysis has been utilized to analyze stress and strain fields and design a new configuration in orthopedics and implant dentistry. Load transfer and stress analysis at implant bone interface are important factors from treatment planning to long term success. Bone configuration and quality are different according to anatomy of expecting implantation site. The purpose of this study was to compare the stress distribution in maxilla and mandible according to implant length and bone engagement types. A three dimensional axi-symmetric implant model(Nobel Biocare, Gothenburg, Sweden) with surrounding cortical and cancellous bone were designed to analyzed the effects of bone engagement and implant length on stress distribution ANSYS 5.5 finite element program was utilized as an interpreting tool. Three cases of unicortical anchorage model with 7, 10, 13mm length and four cases of bicortical anchorage model with 5, 7, 10 and 13mm lenght were compared both maxillary and mandibular single implant situatiion. Within the limits of study, following conclusions were drawn. 1. There is difference in stress distribution according to cortical and cancellous bone thickness and shape. 2. Maximum stress was shown at the top of cortical bone area regardless of bone engagement types. 3. Bicortical engagement showed less stress accumulation when compared to unicortical case overall. 4. Longer the implant fixture length, less the stress on cortical bone area, however there is no difference in mandibular bicortical engagement case.

To determine the clinical and prognostic significance of EEG study in acute carbon monoxide intoxication, the EEGs of 107 patients, whom the study was performed relatively early in the course of intoxication, were analyzed and compared with the clinical courses and CT brain scans retrospectively. The final outcome of the patients consisted of 78 cases of recovery, 20 cases of prolonged coma and 9 cases with delayed neurologic sequeles. Statistically, there was no evidence of the age and sex influencing the clinical outcome or EEG finding. The EEG abnormalities depended upon the level and duration of unconsciousness, showing more abnormal EEG in the patient with deeper and longer coma. Many serial EEGs revealed almost parallel improvement to the clinical recovery but not always. Usually the EEG abnormality had the tendency to persist a little longer than the clinical. The patterns and grades of EEG abnormalities were also important to provide the prognostic significance. Almost all of the patients revealing, rarly in the course, some normal alpha background or high amplitude regular 1.5-2.5 Hz slow waves which looked like triphasic wave would be recovered soon or later. The irregular geneeralized delta slow waves, not responding to the outer stimuli suggested poor prognosis and prolonged coma. The abnormal CT brain scan such as low density in basal ganglia and/or white matter also showed some prognostic value, but not that of EEG studies. The development of delayed neurologic sequeles, however, could not be predicted by EEG or CT brain scan.
