OBJECTIVES: Homocysteine has been associated with cognitive impairment and various psychiatric symptoms. This study was designed to examine the relationship exists between plasma homocysteine concentration and behavioral and psychological symptoms of dementia(BPSD). METHODS: 41 subjects with dementia of Alzheimer's type were included in this study. We carried out history taking, physical examination, and cognitive assessment for the diagnosis of dementia of Alzheimer's type based on DSM-IV. We scored the Mini Mental State Examination(MMSE), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), and the Korean Neuropsychiatric Inventory(K-NPI). We also measured levels of homocysteine, folate, and vitamin B12 in the plasma. RESULTS: We found statistically significant positive correlations between homocysteine concentration with NPI total score, and with scores of several sub-domains such as delusion, agitation/aggression, depression/dysphoria, and elation/euphoria. No significant correlation existed between homocysteine levels and scores of MMSE, GDS, and CDR. CONCLUSIONS: This study shows that plasma homocysteine levels are associated with BPSD. Further research is necessary to identify pathophysiologic mechanisms underlying these relationships.

PURPOSE: To compare the results of two different incision METHODS: scleral tunnel vs clear cornea in cases phacoemulsification and posterior chamber intraocular lens implantation combined with pars plana vitrectomy. METHODS: Between August 2003 and August 2005, 61 eyes with cataract and vitreoretinal diseases were treated by phacoemulsification combined with pars plana vitrectomy and PC-IOL implantation. Preoperative demographic data and postoperative best-corrected visual acuity (BCVA), astigmatism change, and complications were analyzed. RESULTS: The mean age of patients in the scleral tunnel incision (Group 1) and clear corneal incision (Group 2) was 57.09+/-13.72 and 58.83+/-11.83 years respectively. Diabetes mellitus was the most common underlying disease resulting in vitreous opacity. Vision improved in 82% of Group 1 and 78% of Group 2. There was a significant difference in the postoperative astigmatic changes between Group 1 and 2 (1.37+/-1.13D vs 0.78+/-0.67D). No discernible differences such as recurrent vitreous hemorrhage, inflammation in anterior chamber, increased intraocular pressure or iris changes were noted between the two groups. CONCLUSIONS: Although there was no difference in the postoperative BCVA, two different incision methods yielded significant different postoperative astigmatic changes.

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.

PURPOSE: To evaluate the results and complications of transscleral fixation of the foldable intraocular lens(IOL). METHODS: We performed a retrospective review of the medical records of 26 patients who had undergone transscleral fixation of acrylic three-piece foldable IOL from January 2002 to April 2004 in our hospital. There were 5 eyes with aphakia, 2 with idiopathic lens subluxation, 3 with trauma, 5 with dislocation or opacification of IOL, and 11 with complicated cataract surgery. RESULTS: The mean age of the patients was 70.6 years (range, 47~87 years). The range of preoperative best corrected visual acuity (BCVA) was from light perception to 0.6. The mean preoperative refraction and mean preoperative target refraction were 2.0 +/- 6.51D (-8.5~13D) and -0.45 +/- 0.70D (-3.75~0.39D), respectively, in spherical equivalent. The mean preoperative corneal astigmatism was -1.0 +/- 0.65D (-0.25~-2.5D). The postoperative BCVA ranged between 0.02 and 1.0, and the mean refractive error was -0.66 +/- 1.15D (-3.3~1.75D) at the last follow-up visit. The mean corneal astigmatism was -1.55D +/- 1.67 (-9~-0.25D) at the last follow-up visit (p=0.99, paired t-test). CONCLUSIONS: Transscleral fixation of the foldable IOL through small incision results in fewer complications, due to the large incision and the shorter time, and therefore, instantly improved visual acuity.
