A case of Osteogenic sarcoma arised from orbit 4 years after the radiation therapy for retinoblastoma in a 9 years old girl is presented. 4 Years ago, under the diagnosis of retinoblastoma, the left orbital exenteration was performed and was treated with x-ray radiation giving 4.500 gamma tumor dose in 4, weeks. On admission, the left orbital cavity was filled with hard mass and orbital bone revealed extensive destruction with osteoplastic changes on x-ray, and diffuse sarcomatous growth of anaplastic cells with abundant osteogenesis and osteoclastic activity microscopically. It is of authors' opinion that osteogenic sarcoma of orbital bone in this presented case might developed by irradition on retinoblastoma.

BACKGROUNDING/AIMS: It has been nearly established that liver resection for colorectal metastases is a relatively safe procedure with survival benefit to patients. This study was performed to evaluate if the liver resection for colorectal metastases is effective method and to determine the appropriate therapeutic modality. METHODS: Between January 1995 and January 1999, sixteen patients who had liver resectin for metastatic colorectal carcinoma at our hospital were analyzed retrospectively. RESULTS: Wedge resection was performed in 7 patients, segmentectomy in 3 patients, and lobectomy in 6 patients. The median survival time was 26 months and cumulative 1 and 4-year survival rate were 83.1% and 34.6%, respectively. Extent of hepatic resection had marginally influenced the survival(p=0.0514). No prognostic factor was related significantly to survival. Recurrence in remaining liver following the anatomical liver resection was significantly low compared with wedge resection( 12.5% vs. 71.5%, p=0.035). CONCLUSION: Liver resection is an effective and safe treatment for colorectal liver metastases. The anatomical liver resection decreased recurrence rate in the remnant liver. The curative resection with an adequate surgical margin will improve outcome.

BACKGROUND: To evaluate the prognostic factors of seizure recurrence in newly diagnosed epilepsy at 1 year follow up. METHODS: From the IUED (Inje University Epilepsy Database) we retrieved the epilepsy patients who had never before taken any antiepileptics (AED) and were followed up for 1 year. We retrospectively reviewed the medical records with special attention to : a) age of onset, b) history of antecedents, c) seizure frequency before starting AED, d) abnormal neurological examination, e) MRI findings, f) EEG findings, g) epileptic syndrome classification. We defined seizure recurrence as any seizure occurring during the 1 year evaluation follow up except during the AED titra-tion period, having only an aura and being in poor compliance. We analyzed the prognostic factors that could reliably predict the seizure recurrence at 1 year follow up. RESULTS: We found 104 patients (64 male, 40 female) who met the inclusion criteria. The mean age of onset was 23.7 years. Of 104 patients 19 had generalized epilepsy, 82 had partial epilepsy and 3 had unclassified epilepsy. Thirteen percent (13/104) developed seizure recurrence at the 1 year follow up. Significant univariate associations were noted between seizure recurrence and these factors: presence of antecedents [odds ratio (OR) 4.8; 95% confidence interval (CI) 1.2-18.5 ], post-encephalitic epilepsy (OR 7.7; 95% CI 2.1 ~ 28), and abnormal neurological examination(OR 14.6; 95% CI 3.9-55). With multivariate logistic regression, the independent predictor of seizure recurrence was the abnormal neurological examination (OR 9.7; 95% CI 2.4 ~ 39.4). CONCLUSIONS: The chance of developing a seizure recurrence at the 1 year follow up was 13 percent and the prognostic factors were the presence of antecedents, post-encephalitic epilepsy and an abnormal neurological examination.

PROPOSE: There have been many debates about the ideal surgical technique for acute Achilles tendon rupture. The purpose of this study is to review and analyze the clinical outcome of the acute Achilles tendon ruptures that had been repaired by indirect suture technique with minimal incision that utilized an instrument called Achillon (Newdeal, France). MATERIALS AND METHODS: This study is based on the 14 cases (14 patients) of acute Achilles tendon total ruptures that have been repaired by minimal incision technique utilizing Achillon instrument from June 2003 to December 2004. Two cases were reruptured before 8 weeks and repaired again using Krackow suture which left 12 feet for postoperative functional evaluation with at least 6 months of follow-up. Ten cases were men and average age at time of injury was 34.4 (26-49) years. The time from injury to surgery was an average of 4.5 (1-9) days and the postoperative evaluations were done by an Arner-Lindholm scale and AOFAS score. The ability to return to original work and sports activities as well as patient satisfaction were also evaluated. RESULTS: The follow-up period was averaged for 13.2 (6-24) months. Seventy-one percent of cases were ruptured during sports activities. The ruptured level was the average of 5.1 cm (3.2-8 cm) above calcaneal attachment and the skin incision was averaged for 2.7 cm (2.5-3.0 cm) long. At final follow-up, standing on tip-toe was possible in all cases while the heel-floor height on ruptured side was shorter by 0.7 cm (0-2 cm). By Arner-Lindholm evaluation scale, 9 cases were excellent, and 3 cases were good. Overall AOFAS score was an average of 96.1 (94-100), and all patients were satisfied with the result. Patients returned to work at an average of 1.3 months after the surgery and pre-injury sports activities were all possible from at 6 months after operation. CONCLUSION: Since we have treated acute Achilles tendon ruptures with minimal incision technique utilizing the Achillon and gained encouraging functional results with all patients returning to previous work with high patient satisfaction, this technique could be recommended as one of the ideal surgical options for the Achilles tendon ruptures.

We have performed photorefractive keratectomy(PRK) and Laser In situ keratomileusis(LASIK) to compare the clinical results of PRK with that of LASIK in moderate myopes retrospectively. Of 70 eyes who were between -4.0 diopter and -8.0 diopter, there were 40 eyes, 33 patients treated by PRK and 30 eyes, 23 patients treated by LASIK. Follow-up evaluations were done at 1, 2, 3, 6, 9 months and uncorrected visual acuity, best corrected visual acuity, spherical equivalent, corneal haze, complications were analized. The postoperative uncorrected visual acuity was 0.72, 0.86, 0.86, 0.91, 0.85 in PRK and 0.86, 0.86, 0.83, 0.85, 0.82 in LASIK and the best corrected visual acuity was 0.94, 0.97, 0.97, 0.99 0.97 in PRK and 0.96, 0.97, 0.97, 0.97, 0.96 in LASIK respectively. Although the postoperative refractions within +/-1 diopter of emmetropia were 32.5% in PRK and 76.7% in LASIK and statistically significantly different between the two groups at 1 months(P<0.05), the difference was not significant(P>0.05) from 2 months. The average corneal haze was not significant(P>0.05) from 2 months. The average corneal haze was decreased from Grade 1.66 to Grade 0.48 in PRK at 1, 6 months but in LASIK, the corneal haze was low grade of Grade 0.35 from 1 month. The complications of PRK were irregular astigmatisms in 2 eyes and that of LASIK, the corneal haze was low irregular astigmatisms in 2 eyes and that of LASIK were interface particles in 3 eyes, irregular astigmatisms in 3 eyes. The clinical results of PRK and LASIK were satisfactory and the two technical methods were effective for correction of moderate myopes.

PURPOSE: To report one case which has been showed successful results after prosthokeratoplasty using `Cardona Bolt and Nut' model. Even though prosthokeratoplasty has a high rate of failure within 5 years after surgery because of many complications, But there was no complications over a 16-year period in this case since surgery by one of the authors (J-H K). METHODS: This patient had an alkali burn on both his eyes due to the accidental explosion of carbamate in 1979 when he was 26 years old. His corneas were densely pacified with neo-vascularization despite undergoing keratoplasty once on his right eye, and twice on his left eye. To improve his vision, we performed ultimately a successful Cardona Bolt and Nut prosthokeratoplasty on his right eye in 1988. RESULTS: During the period of to 16-year follow-up the visual acuity of his right eye was maintained at 0.1 without correction, and 0.15 with correction (+7.0 D.), even though his visual field narrowed(within 10 degree) due to the long and narrow optical cylinder.

PURPOSE: To make an optic nerve crush injury model and to investigate the neuroprotective effect of intravitreally injected ciliary neurotrophic factor (CNTF) on rat retinal ganglion cells (RGCs) in the model. METHODS: The optic nerves of 12 Sprague-Dawley rats were crushed at 3 mm posterior to the eyeball for 1 minute using aneurysm clip (110 g). Two micrograms of CNTF in 2 micro liter of vehicle was injected intravitreally in one group (n=6) and 2 micro liter of PBS was injected in the control group (n=6) at 4, 7, and 10 days after the optic nerve injury. After 2 weeks, the retrograde labeling of the RGCs was done by the dextran tetramethylrhodamine. Twenty-four hours after the labeling, the retina was wholly mounted and the labeled RGCs were counted under the fluorescence microscope. RESULTS: The death of RGCs in this model began at 1 week and continued for 3 weeks. The number of labeled RGCs in CNTF-injected group (510+/-139/mm2) were significantly higher than that in control group (345+/-87/mm2)(p<0.05). CONCLUSIONS: The optic nerve crush injury model was established by use of aneurysm clip. In this model, the intravitreally injected CNTF had a neuroprotective effect on the rat RGCs.

PURPOSE: To report the experience of treating chronic granulomatous canaliculitis induced by permanent silicone punctal plugs used for dry eye syndrome treatment. METHODS: The transformation of puncta below both eyes and secretions in the lacrimal duct were observed for a 56-year-old female patient who had attended hospital for 4 months due to epiphora and secretions. Under the diagnosis of lacrimal duct inflammation for the lower lacrimal duct of both eyes, three-snip punctoplasty, curettage in the lacrimal duct, and pathological examination on the part of the lacrimal duct obtained from the three-snip punctoplasty were carried out. RESULTS: The lacrimal silicone plugs were removed from the lacrimal duct at the time of the lacrimal duct curettage, and a diagnosis was made based on tissue biopsy of chronic granulomatous canaliculitis induced by permanent silicone punctal plugs. After the above surgical operations, the epiphora and the anterior eye segment symptom both disappeared. CONCLUSIONS: The permanent silicone punctal plug used to permanently close the lacrimal punctum scarcely causes disorder in the lacrimal drainage system with epiphora and inflammation by acting as a foreign substance. It therefore should only be used when essential.
