The anatomic and physiologic changes of the anopthalmic orbit affect cosmetic appearance of the patient and function of the socket and the prosthesis. During the past three years, the authors studied 13 cases of dermis-fat graft and 27 cases of posterior Tenon's capsule suturing with a plastic implant, and compared the post'operative effects of the two procedures. Dermis-fat graft produced good fornix formation with no remarkable fat atrophy after both primary and secondary proceddure. Posterior Tenon's capsule suture technique showes good effect to keep implant from migration or extrusion. Size of the plastic implant and fixation of the extraocular muscles were important factors also for good cosmesis and implant motility. There revealed no significant difference between the two procedures in EOM motility, enophthalmos, deep superior sulcus deformity, implant migration or prolapse etc.

Symptomatic epiphora has been rarely observed in patients jwith only one canaliculus obstruction. The authors experienced 7 cases of only lower canahculus obstruction without epiphora. Tear drainge of these eyes was assessed using dacryoscintigraphy and compared with the comtrol eyes. The measurement of T1/2 valuse, the duration of which a given amount of 99m-Tc-phytate drops to half in the conjunctival fornix was performed. The T1/2 valuse was 368.1 seconds in average in the eye with the lower canaliculus obstruction and 263.3 seconds in the control eyes(p Drainage* ; Humans ; Lacrimal Apparatus Diseases ; Tears*

This study was carried out to compare the clinical effect of the endonasal lacrimal surgery done in 75 eyes of the 62 patients with that of the conventional lacrimal surgery done by the same operator in 72 eyes of the 57 patients. The diameter of intranasal ostium was 1.9 +/- 0.4 mm in endonasal approach and 2.6 +/- 1.4 mm in skin approach (p<0.05), respectively. Postoperative hospitalization were 1.7 - 2.5 days shorter in endonasal lacrimal surgery than those of conventional lacrimal surgery (p<0.001). Satisfactory tear drainge was observed in 29 eyes (90.6%) after endonasal dacryocystorhinostomy and in 28 eyes (90.3%) after conventional dacryocystorhinostomy, and 41 eyes (95.3%) revealed astisfactory tear drainge after endonasal conjunctivodacrystorhinostomy and 39 eyes (95.1%) showed good results after conventional conjunctivodacr yocystorhinostomy. In summary, endonasal lacrimal surgery showed no cutaneous scar, less edema and hematoma with short recovery time and similar success rate to the conventional lacrimal surgery. Thus, endonasal lacrimal surgery might be better than conventional lacrimal surgery.

PURPOSE:It is important to evaluate the healing process of avascular necrosis (AVN) involving femoral head after treatment. The purpose of this study was to assess the usefulness of pinhole bone scintigraphy in the AVN of femoral head after surgery. MATERIALS AND METHODS: We analyzed the changing pattern of pinhole bone scintigram in 21 femoral heads of 16 patients (14 lesions/11 male, 7 lesions/5 female, mean age: 39.4 yrs) before and after multiple drilling or vascularized bone grafting for AVN of the femoral head. In all patients, pre-operative scintigrams were obtained at 1 to 3 months before treatment and the first post-operative scintigrams were obtained at 1 to 3 months after treatment. All patients were followed for 2 to 4 years after operation. RESULTS: The findings of the pinhole scintigrams were divided into three patterns: 1) curvilinear, 2) scattered spotty and 3) undetermined. The 10 of 11 lesions with curvilinear pattern had good postoperative clinical and radiological follow-up findings. However, all 6 lesions with scattered spotty pattern showed poor postoperative findings, which necessitated total hip joint replacement. Of the 4 lesions with undetermined pattern, 2 required total hip joint replacement. There was significant difference in postoperative prognosis between the curvilinear and scattered spotty patterns (p<0.05). CONCLUSION: We conclude that the pattern of pinhole bone scintigram obtained within 1 to 3 months after multiple drilling or vascularized bone graft operation is a useful prognostic indicator in the AVN of femoral head.

An unusual case of glroependymal cyst involving the lateral ventricle, 3rd ventricle, cerebellopontine angle cistern and prepontine cistern, simultaneously, is reported. The glroependymal cyst is benign developmental cyst that mainly occurs in the cerebrospinal axis in relation to ventricle, but occasionally occurs in relation to extraventricular system, such as subarachnoid space, brain stem and cerebral parenchyme. The histological characteristics of ependymal cyst wall are ependyma-like epithelium and neuroglial tissue.

PURPOSE: Post-authorization survey(PAS) is a useful tool for obtainting wider range of data on the safety and efficacy of new drugs following their approval, as they can detect uncommon, unreported adverse events(AEs), which enables more attention to be directed to the practioners. Especially, the limited number of patients in oncology trial cannot usually give the actual incidence of AEs. METHODS: Since Nov. 1998, when docetaxel gained Korean approval in the treatment of breast cancer, a PAS to investigate its safety profiles has been conducted targeting more than 600 patients over 4 calendar years. RESULTS: Case report forms from 626 out of 646 patients were assessable for safety and 444 for efficacy. The patient characteristics are: mean age, 48.1 years; male/female 4/622; Wt/Ht/BSA 57.9 kg/156.1 cm/1.56 m2 ; stage I-II/III/IV 109 (18.2%)/125 (20.8%)/366(61.0%). In 344 patients, 960 AEs were reported in severity of mild/moderate/severe in 6.7, 40.9 and 51.1 % of cases. From AE results, 36.0% needed dose reduction; 34.3% transient interruption of the cycle; and 1.3% permanent discontinuation of docetaxel. Thirty five serious AEs such as febrile neutropenia, alopecia, diarrhea, abdominal pain and headache were reported in 21 patients. Unexpected AEs such as skin ulcer, discoloration of skin, H. Zoster infection, ulticaria, facial flush, chest pain, hemoptysis, pneumonia, stridor, nasal bleeding, photophobia, haematuria, Cushing's syndrome, hyperglycemia and insomnia were reported regardless of any causal relationship. Factors affecting the development of AEs were age, stage, concomitant medication other than chemotherapeutic agents and the number of cycles treated. The efficacy was evaluable in 444 patients with overall response rate of 36.5% (CR/PR 6.3/30.2%). Factors affecting the efficacy were stage, concommitant medication other than chemotherapeutic agents and the number of treatment cycles. CONCLUSION: This post-authorization survey on the safety and efficacy of docetaxel in breast cancer offers oncology practice in the real world without subject selection as is the case in clinical trials, although it was performed to fulfill the registrative requirement of the Korean health authority with limited data. The efficacy and safety profile of docetaxel in breast cancer was no much different from those reported in clinical trials.

The authors present a statistical survey of the general incidence, age distribution, and preferential site of 631 tumors of the brain which have been surgically treated at Korea university medical center, department of neurosurgery over the last period of 10 years from 1985 to 1994. Among them 269 cases were males and 362 were females. Of the 631 intracranial neoplasms verified histologically, tumors of neuroepithelial tissue comprised 34%(212 cases), tumors of meninges 23%(148 cases), pituitary adenoma 18%(114 cases), metastatic tumors 8%(50 cases), neurilemmomas 8%(49 cases), germ cell tumors 3%(13 cases), cyst and tumor like lesions 3%(16 cases), and lymphomas 1%(5 cases). Of the 178 gliomas, astrocytic tumors comprised 83%(148 cases), oligodendroglial tumors 11%(20 cases), ependymal tumors 3%(6 cases) and mixed gliomas 1.7%(3 cases). Brain tumors occurred most frequently in the age group of 45-50 years, as seen by an incidence of 63 cases(10%). The male to female ratio was 0.74: 1. Tumors that showed a definitive preponderance of females over males were meningiomas, neurilemmomas, and pituitary adenomas. Supratentoral and infratenorial cases were 73%(461 cases) and 26%(162 cases), respectively and the remaining cases involved both sites. Of the 114 cases of childhood and adolescent tumors, 60 were male and 54 were female. Supratentorial tumors were 56% and infratentorial were 44%. The tumors in order of frequency were astrocytomas(28%), primitive neuroectodermal tumors(21%), craniopharyngioma(10%) and so on. Meningiomas occurred most frequently in parasagittal/falx area(25%), followed by cerebral convexity 23%, sphenoid 14%, posterior fossa 13%. Among pituitary adenomas, prolactinomas(32%) were the most common and followed by null cell adenomas 31%, growth hormone cell adenomas 15%, mixed GH-PRL cell adenomas 11%.

PURPOSE: To determine whether CT angiography can predict the parent artery of an anterior communicating aneurysm on the basis of characteristics of the aneurysm and precommunicating anterior cerebral artery. MATERIALS AND METHODS: Eighteen patients with anterior communicating aneurysm were studied prospectively using CT angiography and conventional angiography. The parent artery of an aneurysm was predicted by evaluating aneurysm neck location, direction of aneurysm projection, and size of the precommunicating anterior cerebral artery, as seen on CT angiography. A somatom Plus-4 spiral CT scanner was used and shaded-surface display three-dimensional images were constructed. RESULTS: Aneurysm neck was located near the parent artery in 12 cases(66.7%), and aneurysm projection was against the parent artery in 11 cases(61.1 %). The parent artery of the anterior cerebral artery was larger in 15 cases (8 3 .3 %), including ten cases of hypoplasia or agenesis of the contralateral anterior cerebral artery. In 17 of 18 aneurysms(94.4%) the parent artery seen on DSA was correctly predicted by CT angiography. CONCLUSION: Teh parent artery of an anterior communicating aneurysm can be predicted by evaluating a-neurysm neck location, direction of aneurysm projection, and precommunicating anterior cerebral artery, as seen on CT angiography.

Struma ovarii is a monodermal teratoma composed totally or in overwhelming proportion of thyroid tissue. It is uncommon and accounts for 1% to 3% of benign teratomas of ovary. Grossly, they are encapsulated neoplasms, several centimeters in diameter and have a red, shiny, and meaty surface. Microscopically, the tumor is composed of mature thyroid tissue consisting of various sizes, lined by a single layer of columnar or flattened epithelium. The clinical behavior is benign, and simple excision is adequate treatment. We had experienced two cases of struma ovarii arising in the left ovaries. So we report above cases with brief review of literatures.
