Massive hemorrhage into an intracranial neurinoma is a rare event. A 42-year old man noticed hearing loss, nystagmus, diplopia and paresthesia on the left side of the face. A computerized tomography scan demonstrated a large high density mass in the left cerebellopontine angle. The tumor was successfully removed and postoperative course was favorable. Such a case of acoustic neurinoma which revealed itself through intratumoral hemorrhage has not been previously reported in Korea.

PURPOSE: Angiogenesis is an integral part of wound healing, which is an unwanted process in the postoperative period after trabeculectomy. It was the aim of this study to report on the subconjunctival use of bevacizumab (Avastin(R)) as an antiproliferative agent to augment trabeculectomy. CASE SUMMARY: This clinical interventional case study included 2 patients with secondary glaucoma associated with uveitis who underwent antiglaucomatous filtering surgery combined with a subconjunctival injection of bevacizumab. Limbal-based trabeculectomy was performed, and subconjunctival injections (1.25 mg/0.05 ml) were given at the end of the surgery adjacent to the bleb, which was raised using a single-use 26 gauge needle. At 1 and 2 weeks and 1, 3, and 6 months after surgery, intraocular pressure was reduced in both patients to 11 mmHg with functioning filtering blebs. No complications were observed. CONCLUSIONS: The results suggest that subconjunctival bevacizumab injection may be helpful in reducing the risk of postoperative scarring of the filtering bleb.

6 patients underwnet CT-guided stereotactic biopsy or hematoma aspiration procedure for posterior fossa lesions. Trajectory for biopsy or aspiration was transcerebellar approach. The patients were placed under general endotracheal anesthesia and positioned prone or sitting. No complications were encountered in the postoperative period when this technique was used. Stereotaxic transcerebellar multiple biopsy can safely provide tissue conformation of the neoplastic nature of a posterior fossa lesion thought to be a tumor. In addition, hematoma aspiration has been demonstrated to be safe, reliable, and efficient.

Chondrosarocoma is a malignant, relatively slow-growing cartilaginous tumor that generally has a long natural history. From Feb. 1986 to Jan. 1993, 29 cases of chondrosarcoma were registered in the Department of Orthopedic Suergery of Korea Cancer Center Hospital. We reviewed 23 cases of chondrosarcoma which were treated surgically, aimed at curative procedure. Fourteen patients were male and 9 female. The average age at the time of diagnosis was 31.9(17-59) years. The pelvis was the most frequent site(7 patients) followed by femur(6), scapula(4), tibia(2), and each one case of spine, rib, humerus, and finger. The Enneking s surgical stage was II B (18 cases), II A (1), I B (3) or I A (1). The histological grades were as follows : 4 cases of grade 1; 3 grade 2 and 16 grade 3. Local resection with or without reconstruction were done for 20 cases and amputation or disarticulation 3. Chemotherapy was done in four cases and was not effective. The average follow-up period was 34.2(9-81) months. As complications, local recurrence occurred in 4(17.3%) cases, infection 2(8.7%), fracture 1(4.3%), lymphedema 1 and rediation necrosis of soft tissue 1, Distant metastasis occurred in 7(30.0%) cases: 6 cases to lung and 1 to brain. At final follow up 15 cases were continuous disease free, 3 alive with disease, 4 died of disease and 1 no evidence of disease. The Kaplan-Meier's estimated 5-year actuarial survival rate of total 23 cases was 66. 9%. Seven cases with histopathologic grade less than 2 showed 100% of 5 year actuarial survival rate, even one case is alive with disease at final follow up of 62 months. Fifteen cases of surgical stage II B with histopathologic grade 3 had 55.4% of 5 year actuarial survival rate: ten cases with wide surgical margin 87.5%o five cases with intralesional or marginal surgical margin 25%. Early surgical excision of chondrosarcoma with enough wide surgical margin can prevent local recurrence and metastasis.

There are 3 basic methods for surgical treatment of axillary osmidrosis; 1) method that removes only subcutaneous cellular tissue without removing skin 2) method that removes skin and subcutaneous cellular tissue en bloc, and 3) method that partially removes skin and subcutaneous cellular en bloc as well as removing the subcutaneous cellular tissue of the adjacent region. We studied the results of partial removal of the skin and subcutaneous cellular tissue en bloc, as well as the removal of subcutaneous cellular tissue of the adjacent region to compare the results of the bipedicled flap with the graft conversion method. There was no difference between two methods in results and complication rates. There are 3 advantage to this procedure. First, about 70-80% of apocrine glands were centrally distributed among the axillary hairbearing region therefore, resection of the central portion of axillary hair distribution area is important for good result. Second, the preservation of the subdermal plexus with careful excision of adjacent underlying subcutaneous tissue under the aid of the magnifying surgical loupe, is important for good wound healing. Third, the central excision of the axillary hair distribution area provides good exploration for undermining and defatting of the undersurface of the adjacent area, therefore it tooks a shorter operation time.

Our objective was to evaluate the clinical feasibility of spatial domain filtering as an alternative to additional image reconstruction using different kernels in CT. Kernels were grouped as H30 (head medium smooth), B30 (body medium smooth), S80 (special) and U95 (ultra sharp). Derived from thin collimated source images, four sets of images were generated using phantom kernels. MTF (50%, 10%, 2%) measured with H30 (3.25, 5.68, 7.45 lp/cm), B30 (3.84, 6.25, 7.72 lp/cm), S80 (4.69, 9.49, 12.34 lp/cm), and U95 (14.19, 20.31, 24.67 lp/cm). Spatial resolution for the U95 kernel (0.6 mm) was 33.3% greater than that of the H30 and B30 (0.8 mm) kernels. Initially scanned kernels images were rated for subjective image quality, using a five-point scale. Image scanned with a convolution kernel led to an increase in noise (U95), whereas the results for CT attenuation coefficient were comparable. CT images increase the diagnostic accuracy in head (H30), abdomen (B30), temporal bone and lung (U95) kernels may be controlled by adjusting CT various algorithms, which should be adjusted to take into account the kernels of the CT undergoing the examination.

A case of arterial priapism was treated by superselective transcatheteric autologous clot embolization of cavernosal artery 25 days after blunt periheal trauma. No immediate improvement was noted but the priapism subsided on 48th day after the procedure. Normal physiclogic erectlie function was achieved on 53rd day after the procedure, and the period of postprocedure impotence was shortened, as compared with previously reported cases. Autologous blood clot embolization may be an effective treatment method even in delayed priapism, and superselective technique is thought to be more effective to shorten the postprocedure erectlie dysfunction

PURPOSE: We report a patient with intraocular silicone oil leakage into the subconjunctival space and orbit through an Ahmed glaucoma valve implant. METHODS: A 47-year-old male with high myopia and traumatic retinal detachment underwent in the left eye, pars plana vitrectomy, lensectomy and ultimately intraocular silicone oil placement for traumatic retinal detachment. Subsequently, he developed intractable glaucoma and underwent a superotemporal Ahmed glaucoma tube implant, left eye. RESULTS: Intraocular silicone oil migrated through the Ahmed valve into the subconjunctivalspace and orbit. The Ahmed glaucoma valve was removed with excisional biopsy. CONCLUSIONS: Silicone oil migration through an Ahmed valve may be observed after retinal detachment repair with intraocular silicone oil. An Ahmed valve implantation should be done with great care.
