PURPOSE: To compare clinical outcomes of the tumor prosthetic replacement and osteosynthetic fixation for pathologic fracture of skeletal metastatic lesion of the proximal femur. MATERIALS AND METHODS: From 1994 May to 2009 May, medical records of 22 patients who underwent tumor prosthetic replacement with tumor resection (group 1) and 15 others (16 hips) who underwent osteosynthetic fixation without tumor resection (group 2) were reviewed. The mean age of overall patients were 59 (group 1) and 60 (group 2). Mean follow up periods were 23 and 11 months. The oncological and functional results were evaluated with Kaplan-Meier methods and Musculoskeletal Tumor Society (MSTS) scoring system, 1993. The statistical evaluation was assessed with Log rank test and t-test. RESULTS: The mean survival periods were 24 months in group 1 and 11months in group 2. The 1 year survival rates were 86% in group 1 and 50 % in group 2, and 2 year survival rates were 29.7% in group 1 and 9.4% in group 2. The mean MSTS functional score were 26.4 (19-30), 87.9% in group 1 and 15.3 (10-23), 51.0% in group 2. CONCLUSION: The results of tumor resection and prosthetic replacement in selected cases was better than osteosynthetic fixation without tumor resection for metastatic bone tumors around proximal femur in oncological and functional aspects.

Pulmonary endomertiosis is a rare disorder with the typical symptom of hemoptysis during menstruation (catamenial hemoptysis). We report a case of a 19-year-old woman, gravida 0, with 3-month history of catamenial hemoptysis which was confirmed with chest computed tomography. She was treated by means of thoracoscopic wedge resection for the right lesion and fuperior segmental resection through the left thoracotomy, successively. Preoperative fluoroscopy-guided hooking for thoracosopic target lwsion was helpful in circumstances with one lung anesthesia. Four months of follow-up after an uneventful discharge revealed out no recurrence of catamenial hemoptysis in symptoms and images.

Glucocorticoids are usually given according to a standard dosing protocol regardless of individual difference. We evaluated the pharmacokinetic characteristics of methylprednisolone and the degree of interpatient variation in stable Korean renal transplant recipients during the period of 15-21 days after transplantation. This study included 23 renal transplant recipients, 13 males and 10 females, who received kidneys from living donors with stable graft function and without episode of acute rejection. On the study day at 8 A.M., 16.3mg of ethylprednisolone sodium succinate (i.v.) was administered to each patient instead of usual dose (20mg) of prednisolone (p.o.) after sampling of 7cc of baseline blood and additional blood samples were drawn after starting infusion. Plasma was separated and analyzed for methylprednisolone level using high performance liquid chromatography (HPLC) assay, and parameters for pharmacokinetics were calculated. There was significant interpatient variation in the pharmacokinetics of methylprednisolone in our patients group. There was no significant difference in the pharmacokinetic parameters between patients with and without side effects of steroid. Korean renal transplant recipients had higher volume of distribution than black renal transplant recipients; lower clearance than white renal transplant recipients; longer t1/2 than both black and white renal transplant recipients. Even if the number of patients included in this study was too small to reach conclusion, the differences in the pharmacokinetics of glucocorticoids do not seem to be a significant risk factor for side effects of steroid after transplantation. It may be necessary to individualize the dose of a glucocorticoid to achieve an optimal effect and also we need to establish a new steroid regimen protocol for Korean renal transplant recipients.

PURPOSE: To analyze the hyperacuity defects of preferential hyperacuity perimeter (PHP) in myopic CNV and correlate with the other macular anatomical or physiological properties obtained with fluorescein angiography (FA), Optical coherence Tomography (OCT), and central perimeter. METHODS: Seven patients with myopic CNV diagnosed by FA underwent PHP, OCT, central visual field (VF). We examined the locational correlation among FA, central VF and PHP hyperacuity defect and then compared PHP hyperacuity defect with the CNV size by OCT. Also we made a comparison with macular sensitivity change in VF and hyperacuity defects change in PHP after PDT in 4 patients. RESULTS: All the 7 eyes with myopic CNV tested positive for hyperacuity defects. 5 eyes showed locational correlation among PHP and FA, central VF. The size of hyperacuity defect of PHP and CNV size by OCT was positive correlation (p=0.007). Four eyes treated with PDT showed decrease of PHP hyperacuity defect size and changes in location according to decrease of CNV size after PDT. CONCLUSIONS: Our results suggest that the PHP may be used to detect myopic CNV and beneficial for analyzing functional effect following PDT in myopic CNV patients. These results require further validation in a larger population.

Caudal anesthesia for total hip replacement in geriatric patients has been evaluated clinically. The caudal epidural puncture was performed by a 22 G short needle through sacral hiatus with a lateral decubitus position. 1.5% lidocaine 20 mL and 0.5% bupivacaine 15 mL mixed with 1:200,000 epinephrine and 2 mg morphine was used as an anesthetics. The results were follows ; 1) The onset of caudal anesthesia was 7.9+/-4.5 min (2-20 min) and the duration was 4.8+/-3.0 hrs (1-12 hrs). 2) Anesthetic sensory level was not related with the patient's weight or height. 3) The failure rate including systemic toxicity was 13%. 4) The most common complication was hypotension and its incidence was 26.6%. 5) Time to first analgesics was 8.3+/-3.6 hrs. These results indicate that caudal anesthesia in lateral decubitus position is a recommendable anesthetic technique for total hip replacement in geriatric patients. However, the further studies for the determinations of the optimum dose of local anesthetics are needed.

The common cause of tracheoesophageal fistula(T-E fistula) after tracheal intubation is ulceration and necrosis of the posterior wall of trachea by compression pressure generated by cuff. We experienced a young woman sustaining a T-E fistula which was found on the 12th day of intubation for cardiopulmonary resuscitation. Because spontaneous closure of the fistula is far uncommon, operative closure should be aimed for and should be done as soon as diagnosis is conformed. We delayed operative closure because of poor general condition of the patient. In spite of delayed reconstruction, the tracheal reconstruction itself was successful, but the patient died of peritonitis induced sepsis on the postoperative 41th day.

BACKGROUND: Mitral stenosis (MS) and mitral regurgitation (MR) have different pathophysiologies and left ventricular function after miral valve replacement (MVR) in both diseases has been well known. However, there has been no report comparing the change of right ventricular (RV) function immediately after MVR. We evaluated the change of RV function following MVR in MS and MR using a RV ejection fraction (RVEF) thermodilution catheter. METHODS: With IRB approval, 27 patients with MS and 22 patients with MR undergoing MVR were included. Patients with tricuspid regurgitation were excluded. A RVEF catheter was inserted before the induction of anesthesia. Hemodynamic parameters were measured after anesthesia (T1, control), immediately after the termination of cardiopulmonay bypass (T2) and after the sternum was closed (T3). RESULTS: Pulmonary capillary wedge pressure (PCWP) and end systolic and end diastolic RV volume index (RVESVI and RVEDVI) were higher in MS than in MR and there was no difference in RVEF at T1. Heart rate increased and mean pulmonary artery pressure (mPAP), PCWP, and pulmonary vascular resistance significantly decreased at T2 in both groups. RVEF increased and RVESV and RVEDV decreased significantly only in MS after MVR versus that at T2. There was no difference in hemodynamic parameters between both groups at T2 and T3. CONCLUSIONS: RV function was significantly improved in MS but not in MR after MVR. However, there was no significant hemodynamic difference between MS and MR after MVR, though they are known to have different preoperative pathophysilogies and postoperative left heart functions.
