To introduce a case of Centeral Retinal Artery Occlusion in Gas Tamponade State after Viterctomy for the treatment of Retinal Detachment. A 47-year-old male patient with histories of LASEK surgery 15 years ago and cataract surgery 8 years ago visited our clinic with complaints of sudden visual disturbance in his right eye. He was diagnosed as regmatgenous retinal detachment and underwent pars plana vitrectomy, endolaser photocoagulation, 14% C3F8 gas tamponade, and subtenon triamcinolone injection. After the surgery, the retina was well attached and the visual acuity was improved from finger count 30cm at post-operative day 1 to 0.08 after the 2 weeks of surgery. Intraocular pressure was maintained 20~25 mmHg by Brimonidine/timolol eye drop treatment. The best corrected visual acuity was reduced to hand motion at post-operative day 15. Retinal arteriol attenuation and pale optic disc with 1/3 gas filled vitreous cavity was identified at post-operative day 30. Post-operative 2 years, visual acuity was non light perception with severe narrowing of arteriole and diffuse retinal pigment epithelial atrophy; no retinal vascular flow was observed on fluorescein angiography. Gas tamponade state after viterctomy for the treatment of retinal detachment at high myopia may be risk factors of central retinal artery occlusion.

The sling operation is especially indicated in patients with intrinsic sphincter dysfunction (ISD). We evaluated of the effectiveness of the sling operation for the treatment of genuine stress incontinence patients with ISD. We operated 7 patients and followed up all of the patients for 214 (mean 8) months. Preoperative maximal urethral closure pressure was ranged from 23 to 74 (mean 38.4) cmH2O and valsalva leak point pressure (VLPP) was ranged from 41 to 78 (mean 59.5) cmH2O. We applied rectus fascia or GoreTex mesh as sling material. As a results, genuine stress incontinence (GSI) had completely cured in all of 7 cases. However, postoperative urinary retention was developed in two cases. In one of these, we released suspension suture, and in another case, urethrolysis and Raz operation was underwent in other hospital. All of these two cases showed improvement of voiding and any recurrence of incontinence was not noted. In conclusion, GSI due to ISD can be cured by the technique of the sling operation, so we suggest that the sling operation is one of the treatment for GSI patient with ISD.

STUDY DESIGN: Clinical and radiographic results of spine fracutre treated with pedicle screws and hooks were reviewed. OBJECTIVES: Evaluate the efficacy of tile pedicle screw and hook for thoracolumar bursting fracture. SUMMARY OF LITERATURE REVIEW: Despite of the mechanical advantage of the pedicle screw, the metal failure in short segment fusion has been reported. A biomechanical study showed additional laminar hook increased rotational strength. MATERIALS AND METHODS: Between 1994 and 1996, seventeen patients who had a Denis type B bursting fracture of the thoracolumbar spine were treated by posterior instrumentation with pedicle screws and laminar hooks and auterior interbody fusion after partial corpectomy. They have been followed for an average of 13.4 months. RESULTS: At last follow-up, radiographs showed successful fusion of the injured spinal segment in all patient. The subsidence of grafts which were used In anterior interbody fusion was an average of 0.76mm. There was a loss of 2.6 degrees on average in the correction of the kyphosis. No patients had screw breakage or loosening. CONCLUSIONS: We concluded that posterior fixation with screws and hooks, anterior decompression by partial corpectomy, and strut-grafting in patient who had a Denis type B bursting frafture of the thoracolumbar spine yielded good radiographic and functional results.

PURPOSE: To identify differences in the refractive error of postoperative intermittent exotropia patients. METHODS: A total of 71 patients who had an average refractive error of 2 D and a follow-up of more than 6 months after unilateral recession-resection (R&R) for intermittent exotropia were included in this study. Patients were divided into 3 groups according to their refractive error: Group 1, < or =-1.0 D; Group 2, -1.0 D ~ +1.0 D; Group 3, > or =+1.0 D. The amounts of deviation 1 day after surgery and 6 months after surgery were evaluated. RESULTS: Out of the 71 total patients included in this study, group 1 included 20 patients, group 2 included 39, and group 3 included 12. The average refractive error in groups 1, 2, and 3 was -2.2 +/- 0.9 D, 0.0 +/- 0.4 D and +1.9 +/- 0.9 D, respectively. The angle of deviation 1 day after surgery was measured in the 3 groups; A result labeled '+' was considered to be exodeviation and a result labeled '-' was considered to be esodeviation. The angle of deviation results for groups 1, 2, and 3 one day after surgery were -6.7 +/- 6.0 PD, -7.5 +/- 5.8 PD and -7.3 +/- 5.9 PD (p = 0.937), respectively, and the results 6 months after surgery were +2.2 +/- 4.3 PD, +4.7 +/- 5.9 PD and +1.8 +/- 2.8 PD (p = 0.076), respectively. Among the 3 groups, no statistically significant difference was observed in postoperative angle of deviation after 6 months. CONCLUSIONS: In basic intermittent exotropia patients with an average refractive error of 2 D, the amount of refractive error makes no difference in strabismus surgical outcomes.

Alveolar soft-part sarcoma is a rare malignant neoplasm. It occurs most commonly in the deep tissue of the extremity, particularly in the anterior aspect of the thigh. It usually presents as a slow-growing, painless mass with little functional impairment. Because of the relative lack of symptoms, it may be easily overlooked. The course of the disease tends to be long but unrelenting, and local recurrences are frequent. There were no lifetime cures in the reported cases. This tumor is relatively unknown to orthopaedic surgeons, and a wider knowledge of its characteristics may lead to its more frequent recognization, Recently, two cases of alveolar soft-part sarcoma were encountered on the orthopaedic department of Dong-kang Hospital, Ulsan. In case 1, the tumor was found in the vastus lateralis muscle; and in case 2, vastus intermedius muscle. The authors will present these cases in detail to provide a glance at this very rare but more frequently recognizable tumor, the alveolar soft-part sarcorna.

Purpose: The Korean Society of Medical Education (KSME) was founded in 1983 and celebrated its 40th anniversary in 2023. This study examines the evolution of topics discussed at KSME conferences from 1971 through 2023, highlighting shifts in the focus of medical education. Methods: We analyzed 90 KSME conferences over 5 decades (1970s, 1980s, 1990s, 2000s, and 2010s), categorizing the topics into three eras based on emerging themes and continuity. Results: Consequently, 37 topics covered at the conference were categorized. Ten topics continuously appeared from the 1970s to the 2010s, including future directions of medical education, teaching methods, faculty development, and curriculum. The topics from the 1970s to the 1990s included 14 areas, such as medical education evaluation, non-undergraduate curriculum, community-related, and research. Thirteen new topics emerged after the 2000s, such as social accountability, student support, professionalism, and quality improvements. The most common topics under innovations in medical education, a case of curriculum innovation at universities that began after 2000, were clinical clerkship, curriculum development, and medical humanities. Conclusion KSME’s selection of conference topics has been strategically aligned with societal needs and the evolving landscape of medical education. Future topics should continue to address relevant societal and educational challenges.

Thirteen patients with malignant germ cell tumars of the ovary have been treated with a combination chemotherapy. The age of the patients ranged from ll to 50 years and there was no history of radiation therapy of chemotherapy except operation, Stage distributions are as follow ; 2 pstients are stage IV, 3 are stage II and remainied 8 are stage I. 4 patients with immature teratama and 2 patients with mixed germ cell tumor received VAC chemotherapy, as primary therapy, and among them 1 lost to follow up but remained 5 cases live without evidence of disease 39 to 83 gnontha. There were 3 patients with endodermal sinus tumor and 1 received VAC and remeined 2 received FVB as primary chemotherapy, Of them 1 died of disease after 9 months of oyeration and the other 2 live now with no evidence of disease. There were 2 patiente with dysgerminoma and 2 with primary ovarian choriocarcinoma. 1 patient with dysagerminoma and 1 wit choriocarcinoma were died because of chemotherapy toxicity, 1 patient with dysgerminoma, who refused further ehemotherapy after l course of chemot.herapy, died of progressive disease. l patient wit choriocarcinoma now live well without evidence of disease at 35 months. The combination chemotherapy using VAC or PVB regimen represents an effective treatment for malignant. germ cell turnars of the ovary and reveals moderate oxicity.

PURPOSE: The aim of this study was to compare the treatment efficacy of photodynamic therapy (PDT) and focal laser photocoagulation in chronic central serous chorio retinopathy (CSC). METHODS: A retrospective study in a clinical practice setting including 40 eyes of 40 patients with chronic CSC which were treated with PDT or focal laser photocoagulation were recruited in this study from March 2011 to December 2013. Mean change in best corrected visual acuity (BCVA), presence or absence of resolution of subretinal fluid (SRF) and pigment epithelial detachment (PED), recurrence rate, and complications were analyzed. RESULTS: PDT was performed in 23 eyes of 23 patients and focal laser photocoagulation was performed in 17 eyes of 17 patients, and all patients were followed up for more than six months. Location of leakage point and appearance of leakage showed no statistically significant difference between the two groups. Both groups showed significant improvement in BCVA at one month and six months after the treatment; however, there was no statistically significant difference in BCVA improvement between the two groups. In both groups, SRF and PED were partially or completely resolved. Resolution of SRF was better in the PDT group at one month after the treatment; however, no statistically significant difference in the resolution period was observed between the two groups. None of the patients experienced adverse events in the PDT group, but one patient developed choroidal neovascularization after treatment in the focal laser photocoagulation group. Two patients showed recurrence in the PDT group and needed retreatment. CONCLUSIONS: Both treatments are beneficial in patients with chronic CSC. Focal laser photocoagulation can be a good treatment option in terms of cost-effectiveness and convenience.

STUDY DESIGN: Retrospective study. OBJECTIVES: To demonstrate the fusion rate, degree of subsidence and donor site morbidity of anterior cervical interbody fusion with autogenous bicortical iliac bone graft and anterior cervical locking plate. SUMMARY OF THE LITERATURE REVIEW: In anterior cervical discectomy and fusion with autogenous tricortical iliac bone graft, a large percentage of patients report chronic donor site pain. MATERIALS AND METHODS: Retrospective research was done for 39 patients who underwent anterior cervical interbody fusion with autogenous bicortical iliac bone graft, from January 2006 to July 2011, with a follow up period of longer than 1 year. Fusion rates and subsidece of the graft is estimated with radiographs. Neck pain and donor site pain was estimated with visual analogue scale (VAS) and dysfunction was estimated with the neck disability index (NDI). RESULTS: A 95% of patients who underwent anterior cervical interbody fusion with autogenous bicortical iliac bone graft revealed definitive fusion with little amount of subsidence. The mean VAS score was 0.7 on the donor site and the mean NDI score was 3.8 at the final visit. There was excellent clinical outcome without complication at the donor site or the recipient site. CONCLUSIONS: Anterior cervical interbody fusion with autogenous bicortical iliac bone graft showed high fusion rates and minimal subsidence with excellent clinical outcomes. Therefore, bicortical iliac bone graft is an effective operational procedure in anterior cervical interbody fusion.

Retroperitoneal fibrosis is a rare fibrosing reactive process, which is characterized by diffuse or localized fibroblastic proliferation and chronic lymphoplasmacytic infiltration in the retroperitoneum causing compression or obstruction of the ureters, aorta, or other vascular structures. The majority of cases are idiopathic. A 35-year old woman was transferred for further evaluation and the management of a mass in the left adrenal area. She suffered from vague abdominal pain, which was dull, non-colicky and poorly localized. She had no obstruction of the ureters or vascular structures. The preoperative diagnosis was a tumor of the left adrenal gland. A solitary retroperitoneal mass was excised, which was proven to be localized idiopathic retroperitoneal fibrosis. She was discharged on the 9th post operative day without any complications.
