Ameloblastic fibrosarcoma is an extremely rare variety of odontogenic tumor. It has not previously been reported in Korea. The tumor is composed of benign odontogenic epithelium with a mesenchymal part which exhibits the histologic features of fibrosarcoma. We have reported a case of amloblastic fibrosarcoma of the mandible in a 26-year-old man with swelling of right mandible for 2 weeks. The tumor showed yellowish ill-demarcated ulcerating mass involving right premolar and molar area. Light microscopy revealed irregularly arranged strands and islands of odontogenic epithelium surrounded by abundant mesenchymal tissue with the feature of fibrosarcoma. The fibrosarcoma cells were strong positive on immunostain for vimentin and ameloblastic cells were weakly positive for cytokeratin. S-100 and CEA were negative in both epithelial and sarcoma cells. The sarcoma cells were corresponding to fibroblasts on the electron microscopy with abundancy of RER and mitochondria and covering of basal lamina. Two types of virus like particles were distributed in the cytoplasm and nuclei of sarcoma cells. We treated the patient with surgery and chemotherapy. The recovery was uneventful and the prognosis is under observation.

Choroideremia is a rare hereditary disease with characteristic fundus that causes night blindness and peripheral visual field loss. The authors encounter choroideremia accompanied by recurrent uveitis. This paper is designed to give a description of the condition, along with an investigation of the literature. Ophthalmological tests and treatments were performed. Characteristic fundus, night blindness, peripheral visual field loss, electroretinography and other manifestations led us to a diagnosis of choroideremia. The anterior uveitis was managed with medication.

We experienced a case of a laparoscopic cholecystectomy in a 64 year old woman with DeBakey type IIIb, Daily type B abdominal aortic dissection diagnosed at the emergency room. Isosorbide dinitrate and propranolol were given for control of blood pressure preoperatively. Fentanyl, propofol, atracurium, lidocaine, esmolol and isoflurane were used for smooth induction, and isoflurane in a mixture of O2, N2O (1:1) were inhaled for maintenance. Intraabdominal pressure for pneumoperitonium was kept to 10 mmHg which was lower than that of usual use. An A-line, ETCO2, pulse oximeter and thoracic bioimpedance were monitored. The patient was anesthetized safely and discharged 3 days after the operation. The hemodynamic changes during pneumoperitonium and it's correlation with aortic dissection are discussed.

PURPOSE: To determine whether the use of prophylactic vancomycin in the irrigating solutions during cataract surgery is associated with increased incidence of cystoid macular edema METHODS: We underwent a study from November 1, 1999 to May 31, 2000 by inserting hydrophilic acryl-IOL after phacoemulsification to patients diagnosed with senile cataract over 60 years of age, without systemic and ocular disease. The patients were divided into two groups, one is the use of prophylactic vancomycin in the irrigating solutions and the other is no use of prophylactic vancomycin. A randomized prospective study on the respective 50 subjects who did not have complications such as intraoperative posterior capsular rupture or other postoperative complications was conducted. We checked ophthalmologic examinations and fluorescene angiography for cystoid macular edema of the two gruops in 1 month and 4 months after surgery. RESULTS: The incidences of clinical or angiogenic cystoid macular edema in postoperative 4 months are 2 (4%), 7 (14%) in vancomycin group and 0 (0%), 2 (4%) in control group respectedly. (p=0.4095), (p=0.0999) There was no statically significant difference between two groups but slightly higher in the vancomycin group than that in control group. Visual recovery had no significant difference between two groups. CONCLUSIONS: There was no statically significant relationship between the use of preventive intracameral vancomycin during cataract surgery and the incidence of cystoid macular edema, but need further study to clear up the relationship of them.

PURPOSE: By statistical analysis, to evaluate the comparison of the intraocular lens (IOL) powers by different formulae in patients who have been treated with excimer laser photorefractive keratectomy (PRK) for mild to moderate myopia. METHODS: A total of 38 consecutive eyes of 23 patients who were treated with PRK for mild to moderate myopia have been followed up for more than 6 months. IOL powers by SRK-II, SRK/T, Binkhorst-II, HofferQ, Holladay formula using autorefractokeratometer measured keratometric (K) values by autorefractokeratometer (RK-2, Canon, Japan) and refraction derived K values were compared . RESULTS: The mean IOL powers using autorefractokeratometer measured K values and refraction derived K values were 20.46+/-0.92 and 20.57+/-0.86 diopter (D) by SRK-II, 20.69+/-0.93 and 20.81+/-0.88 D by SRK/T, 21.27+/-0.94 and 21.40+/-0.95 D by Binkhorst-II, 20.93+/-0.09 and 21.05+/-0.06 D by Hoffer Q, and 20.65+/-0.90 and 20.76+/-0.87 D by Holliday respectively. The mean IOL powers using autorefractokeratometer measured K values and refraction derived K values were high in oder of Binkhorst-II, HofferQ, SRK/T, Holladay, and SRK-II, but there was no significant statistical difference between the IOL powers by SRK/T and those by Holladay (p>0.05). In all formulae, the mean IOL powers using refraction derived K values were higher than the mean IOL powers using autorefractokeratometer measured K values, but there was no statistically significant difference (p>0.05). CONCLUSIONS: In patients with excimer laser PRK treatment for mild to moderate myopia, refractive error after cataract surgery is caused by IOL calculation formula as well as its method for IOL power. IOL powers by Binkhorst-II using refration derived keratometric values of all formulae were statistically highest.

Under the assumption that people go through stages in making dietary behavior change, this study was attempted to apply the stages of a change model for fat intake by examining the associations of social psychological variables with stages of change in dietary fat reduction. Derived from social psychological theories, 10 social psychological variables on motivational beliefs(6), social influence(3) and self-efficacy(1) related specifically to selecting every day diets low in fat were constructed. Fat and energy intakes were assessed by a short form semi-quantitative food frequency questionnaire. The associations of stages of change with motivational beliefs, social influence, and self-efficacy variables and energy and fat intakes were assessed in 333 female adults from large cities in Korea. Dietary stage groups differed significantly on most of the social psychological variables in ways predicted by theory. Motivational factors that lead to a psychological state of readiness to take action were important in the early stages of the dietary change process. Social influences were more important in the stages as people decide to take action. Self efficacy and motivational beliefs, particularly, reduction of perceived barriers were important in maintaining fat reduction behavior. The results of our study indicate differences in stages of change in fat reduction behavior in terms of nutrient intakes and social psychological correlates and suggests that adding a time dimension to social psychological models increases our understanding of dietary change, which assist us in designing nutrition education interventions that are more appropriately targeted by stage of change.
