In 1974, bipolar endoprosthesis was first introduced by Bateman & Giliberty. It has theoretical advantages including minimizing acetabular wear, possible reduction of incidence of stem loosening, lessening of dislocation and easy revision procedure. Various methods for the treatment of fracture of the femur neck have been developed & performed, but it is still called “the unsolved fracture” in certain situation. But the role of it as primary treatment of fracture of the femur neck continues to be controversial. Current clinical results encourage its continued use and expansion of indication. Authors reviewed and analysed 21 cases of bicentric endoprosthesis and 1 case of Giliberty endoprosthesis those have been operated at the Department of Orthopaedic Surgery, National Medical Center from 1981 to 1983. Following results were obtained, l. According to disorder distribution, 14 cases were neglected fracture of femur neck, 2 old fracture, 1 idiopathic femoral head necrosis and 2 avascular necrosis & 1 non-union complicated by femoral neck fracture. 2. Among 20 cases, 8 cases were operated within 1/2 1 month after injury and 6 cases within 1 3months 3. Harris lateral appmach was used in 16 cases (80%) and Modified Gibson approach in 4 cases (20%). There were no significant differences in morbidity during operation and postoperative complication. 4. We used femoral stems those head diameter was 22 and 32mm(Charnley & Miiller type) and head pieces those diameter was 48-51 mm in male and 44–48 mm in Ifemale. 5. 3 cases were stiff in inner bearing without acetabular erosion. 6. In 6 cases more than 2 years followup 1 degree CE angle of Wiberg was increased in 2 cases of youngage respectively without associated hip joint pain. 7. Although inclination of head piece was vertical in 8 cases, fracture and dislocation were not found. 8. The circumference of head piece and opposite femoral head was measured and compared. There were 12 cases (mean 12.6 mm) that of head piece larger than opposite femoral head and 3 cases smaller than opposite femoral head. 9. There was 4 cases of complication (3 patients) and still no reoperation and revision converted to T.H.R. 10. With regard to average 18 months of follow-up, 7 cases of 81–90 Harris hip-rating score, 6 of 91–100, 4 of 71–80 and 3 of 61–70.

PURPOSE: To evaluate the efficacy and safety of vitreoretinal surgery using a 23-gauge transconjunctival sutureless vitrectomy (TSV) system for various vitreoretinal diseases. METHODS: A retrospective, consecutive, interventional case series was performed for 40 eyes of 40 patients. The patients underwent vitreoretinal procedures using the 23-gauge TSV system, including idiopathic epiretinal membrane (n=7), vitreous hemorrhage (n=11), diabetic macular edema (n=10), macular hole (n=5), vitreomacular traction syndrome (n=5), diabetic tractional retinal detachment (n=1), and rhegmatogenous retinal detachment (n=1). Best corrected visual acuity (BCVA), intraocular pressure (IOP), and intra- and post-operative complications were evaluated. RESULTS: Intraoperative suture placement was necessary in 3 eyes (7.5%). The median BCVA improved from 20/400 (LogMAR, 1.21+/-0.63) to 20/140 (LogMAR, 0.83+/-0.48) at 1 week (p=0.003), 20/100 (LogMAR, 0.85+/-0.65) at 1 month (p=0.002), 20/100 (LogMAR, 0.73+/-0.6) at 3 months (p=0.001). In 1 eye, IOP was 5 mmHg at 2 hours and 4 mmHg at 5 hours, but none of the eyes showed hypotony after 1 postoperative day. No serous postoperative complications were observed during a mean follow-up of 8.4+/-3.4 months (range 3-13 months) CONCLUSIONS: The 23-gauge TSV system shows promise as an effective and safe technique for a variety of vitreoretinal procedures. It appears to be a less traumatic, more convenient alternative to 20-gauge vitrectomy in some indications.

A 49-year-old man was referred to our department with profuse serous fluid discharge from a Penrose drain after undergoing internal fixation with metal screws for multiple pelvic bone fractures. A definite ureteral penetration was identified that was orientated from the lateral to the medial aspect of the right distal ureter. The patient was surgically treated with excision of the 2-cm injured ureteral segment, end-to-end ureteroureterostomy, and double J ureteral stent placement. To our knowledge, a penetrating ureteral injury caused by bone drilling has not been reported previously in the published literature. This case shows that surgeons who do pelvic surgery, including orthopedic surgeons, should be familiar with the anatomical relationship of the ureter and its potential injuries.

PURPOSE: To investigate the effects of topical anesthesia combined with patient-controlled sedation analgesia for posterior vitrectomy. METHODS: All patients requiring vitrectomy from December 2003 to January 2004 at Seoul National University Hospital underwent surgery with topical anesthesia combined with patient-controlled sedation analgesia. The levels of intraoperative pain and sedation were recorded. The associations of operation time, combined vitreoretinal procedures, and age with intraoperative pain were investigated. Hemodynamic instability and respiratory depression were checked throughout the operation. RESULTS: Forty-three patients (53 eyes) underwent vitrectomy under topical anesthesia combined with patient-controlled sedation analgesia. The mean age was 51.75 +/- 13.68 years and the sex ratio was 25: 28 (male: female). The mean of VAS (visual analogue scale) was 53.61 (5 ~ 67). The level of intraoperative sedation was grade 1 (64%) or 2 (36%). No anesthesia-associated complications were found. CONCLUSIONS: In spite of relatively high VAS, there were no remarkable difficulties in performing posterior vitrectomy and appropriate levels of intraoperative sedation and cooperation were available without anesthesia-associated complications.

From May, 1975 to August, 1986, we experienced 21 patients with ruptured aneurysm of the sinus of Valsalva. 1) Their ages ranged from 15 to 52 years with a mean age of 26.7 years, and 14 patients were male and 7 patients were female. Among 18 cases of which aneurysms occurred on the right sinus of Valsalva, 15 cases (83%) ruptured into the right ventricle, 1 case (6%) ruptured into the right atrium and 2 cases (11%) ruptured into the pulmonary artery. All 3 cases of which aneurysms occurred on the noncoronary sinus ruptured into the right atrium. 2) Clinical symptoms consisted of dyspnea (95%), palpitation (81%), chest pain (43%), orthopnea (33%), cough (14%), hemoptysis (5%), oliguria (5%), and fever (5%). In all patients continuous heart murmur was audible. Hepatomegaly (48%), pulmonary basal rale (14%), and pretibial pitting edema (19%) were also observed. 3) In all patients diagnosis was made with cardiac catheterization and angiography, and confirmed by operation excetpt one case. 4) Among 20 patients who had been performed corrective surgery, ventricular septal defect was observed in 16 patients (85%), aortic insufficiency in 5 patients (25%), pulmonary infundibular stenosis in 1 patient (5%), patent foramen ovale in 1 patient (5%), and tricuspid insufficiency in 1 patient (5%). Ventricular septal defect was observed in all 16 patients whose aneurysms of the right coronary sinus of Valsalva ruptured into the right ventricle and the pulmonary artery. 5) All patients survived operation, and no postoperative complication was found except 1 patient to whom reoperation was performed because of postoperative aortic insufficiency and detachment of the patch closure for ventricular septal defect. There was symptomatic improvement in all patients.

PURPOSE: To identify prognostic factors associated with a favorable outcome after vitrectomy for patients with macular epiretinal membrane (ERM). METHODS: The authors retrospectively reviewed the records of 63 patients (64 eyes) with macular ERM, who were treated by vitrectomy between 2003 and 2008, and followed for more than 6 months. RESULTS: The mean follow-up period was 13.21 +/- 9.11 months and the mean best corrected visual acuity after vitrectomy was log MAR 0.32 +/- 0.34. Univariate analysis revealed the patients in the group with a postoperative log MAR of 0.3 or better had better preoperative visual acuity and shorter symptom duration; multivariate analysis revealed the same results. In 24 eyes, intraretinal structures which contained pseudoholes, intraretinal cysts, retinal folds and vitreoretinal traction were analyzed with Cirrus HD-OCT, however, there was no correlation with visual acuity after vitrectomy. CONCLUSIONS: The present study demonstrated vitrectomy for macular ERM resulted in favorable visual improvement. The preoperative visual acuity and symptom duration were a significant prognostic factor.

BACKGROUND: The intrathecal grafting of adrenal chromaffin cells as a potential analgesic source, to delivery analgesic substances such as catecholamines and opioid peptides, is known to be effective at treating acute and chronic pain in several animal pain models. We tested whether the intrathecal implantation of encapsulated bovine chromaffin cells reduces cold allodynia in a rat model of neuropathic pain induced by chronic constriction injury of the sciatic nerve. METHODS: Bovine adrenal medullary chromaffin cells microencapsulated in sodium alginate-poly-l-lysin-alginate (APA) were implanted into the subarachnoid space of rats (n = 10) and foot cold sensitivity was investigated using an acetone test. At the end of the study, histology and capsule catecholamine production were evaluated. RESULTS: A significant reduction in cold allodynia was observed in animals implanted with chromaffin cells. In addition, the suppression of cold allodynia was reversed by naloxone. Abundant clusters of viable chromaffin cells stained with neutral red, were observed in the retrieved implants and after nicotine stimulation, and catecholamine was quantified. An ultrastructural study showed no fibrotic reaction against capsules, or disorganised capsules. CONCLUSIONS: These results suggest that intrathecal encapsulated chromaffin cells act as "mini pumps", which continuously deliver analgesic substances and produce analgesia in this chronic pain model of nerve injury-without immunosuppressant.

PURPOSE: We described the presenting symptoms, radiologic features and postoperative course of subependymal giant cell astrocytoma (SEGA) in tuberous sclerosis complex (TSC) patients.METHODS: This is a retrospective study including 12 patients (M:F=9:3) who were pathologically confirmed as SEGA between March 1998 and May 2011.RESULTS: Five teenage patients consisted of four who presented with recently appeared headache, vomiting and visual symptoms and one with seizure were never diagnosed as TSC before this presentation. The others (n=7) presented with seizure and diagnosed with TSC before three years of age, and they were diagnosed as SEGA after median 6.5 (2-14) years. The presenting symptoms were headache or vomiting (n=7), blurred vision (n=3), weakness (n=2) and increased seizure frequency (n=1). Four patients experienced tumor recurrence between five months and three years of follow-up; surgical tumor removal (n=1) and gamma knife surgery (n=3) were done for the recurred tumor. The size of residual tumor increased in two patients and repeated tumor removal was done.CONCLUSIONS: Most of SEGA presented with new onset headache, vomiting and visual symptoms. After surgery, the tumor recurred in 25% of patients. Serial follow-up is essential to detect new lesion and find tumor recurrence in patients with SEGA.

OBJECTIVE: We aimed to examine the efficacy and the safety of venlafaxine extended release (venlafaxine-XR), and its effect on the quality of life in patients with generalized anxiety disorder. METHODS: Fifty three patients who had generalized anxiety disorder were recruited for this study. They showed scores of 18 or higher on the Hamilton Rating Scale for Anxiety (HAMA) and did not have major depression. They were scheduled to be examined 5 times (at baseline, 4, 8, 16 and 24 weeks) and took venlafaxine-XR for 24 weeks with a flexible dosing schedule. The primary efficacy variables were the response and remission rates (response: more than 50% reduction from baseline in HAMA total score ; remission: HAMA total score< or =7). Other variables were the Hamilton Ratng Scale for Depression, Beck Anxiety Inventory, Sheehan Disabilities Scale (SDS), and World Health Organization Quality of Life Assessment Instrument-Brief Form (WHOQOL-BREF). Also, the evaluation on adverse effects was performed. RESULTS: The number of patients who completed 24 weeks of treatment was 32 (60.4%). Twenty one patients who were dropped out included 8 patients with intolerable adverse effects and 7 patients with unsatisfactory treatment response. Response/remission rates were 43.4/32.1% in the last-observation-carried-forward methods and 71.9/53.1% in the observed case data. Treatment with venlafaxine-XR improved anxiety and depressive symptoms during 24 weeks on all efficacy measures. By a completed patient analysis, venlafaxine-XR also significantly improved the disability scores on SDS and the quality of life scores on WHOQOL-BREF. In this study, nausea, palpitation, and severe tremor were common reasons of venlafaxine-XR discontinuation in GAD patients, but any serious adverse effect did not occur. CONCLUSION: Treatment with venlafaxine-XR was effective and well-tolerated for the patients with GAD, and also improved quality of life in the GAD patients.
