BACKGROUND: Endoscopic urologic surgery including transurethral resection of prostate (TURP) requires adequate sacral analgesia for insertion of resectoscope. But epidurally administered local anesthetic does not produce anesthetic effects uniformly. Failure to completely block S1 during epidural anesthesia because of the large size of nerve root has been noted. The purpose of this study to compare the relation between catheter direction and sensory anesthesia. METHODS: Thirty patients scheduled for endoscopic urologic surgery were enrolled. The epidural catheter was inserted at L3-4 using a standard 18 gauge Tuohy needle. In group A (n=15), the Tuohy needle with bevel pointed in a cephalad direction during catheter insertion. In group B (n=15), it pointed caudally. And the catheter was introduced 3 cm into the epidural space. After test dose, 2% lidocaine 5 cc, 0.5% bupivacaine 5 cc and 2% lidocaine 3 cc were administered with fractionate dose through it. The extent of the sensory anesthesia to loss of cold sensation and pin prick test was measured every 5minute for 30 minutes. RESULTS: Analgesia spread to loss of cold sensation and pin prick test was no significant statistical difference between the two groups. In 15 minutes after injection of surgical dose, complete blockade in L5, S1 dermatome was present in both groups. CONCLUSION: Our results conclude that epidural catheter direction is not significantly influence the epidural anesthetic spread including sacral area in continuous lumbar epidural anesthesia in elderly patients.

Deveolopmental coax vara represents coax vara not present at birth but rather developing in early childhood, showing a progressive deterioration in the proximal femoral neck-shaft angle during growth. In order to determine the factors that could affect the results of corrective osteotomy, we evaluated the results of 15 developmental coax vara in 12 patients who had been treated with the femoral osteotomy at the Department of Pediatric Orthopedic Surgery, Seoul National University Children's Hospital, from February 1983 to March 1993. Of the 12 patients, there were 6 boys and 6 girls. Three patients had bilateral operations, 5 patients on the right, and the remaining 4 patients on the left. Average at the onset of symptoms was 4 years plus 5 months(range; from 1 year to 7 years plus 2 months), and average age at the tome of operation was 6 years plus 3 months(range; from 2 years plus 4 months to 10 years). We could obtain the following results: 1. Average post-operative loss of neck-shaft angle was 5% in the cases in which post-operative neck-shaft angle was converted more than 130 degrees, and was 8% in the cases in which post-operative neck-shaft angle was converted less than 130 degrees. 2. Loss of neck-shaft angle was higher during the first post-operative period, and was higher in cases in which the triangular osseous defect was persistent post-operatively. There was no correlation between the post-operative neck-shaft angle and disappearance of triangular osseous defect. 3. The femoral anteversion was converted 8.7 degrees to 27.2 postoperatively. 4. The premature arrest of the capital femoral physis was higher in cases in which the neck-shaft angle was less than 130 degrees postoperatively. 5. Leg length discrepancy, which was 2.1 cm preoperatively, did not change in cases in which the neck-shaft angle was more than 130 degrees postoperatively. However, it was converted to 3.3 cm in cases in which the neck-shaft angle was less than 130 postoperatively. 6. we could observe the femoral head deformity in 6 out of 7 cases in which the operation was performed after 7 years of age. We could draw the following conclusion based on our results: 1. We must correct the neck-shaft angle more than 130 degrees. 2. We could not equalize the leg length discrepancy by corrective osteotomy alone. 3. It may be reasonable to perform the corrective osteotomy before 7 years of age.

BACKGROUND: Propofol and remifentanil are both rapid and short-acting drugs that can be used for sedation and analgesia during monitored anesthesia care (MAC). This study was designed to determine the optimal infusion rates of remifentanil during propofol anesthesia in patient undergoing the varicose vein endovenous laser therapy. METHODS: In this randomized, double-blind study, we evaluated the effects of different remifentanil infusion rates on the requirement doses of propofol, level of sedation, intraoperative recall, respiratory and cardiovascular variables, and recovery. Forty consenting ASA physical status I or II patients undergoing endovenous laser therapy with 1% lidocaine skin infiltration were randomly assigned to one of two treatment groups. All patients received midazolam 0.05 mg/kg intravenously for premedication. Remifentanil was infused at 0.05 or 0.10microgram/kg/min during the anesthesia. Sedation was evaluated using the Observer's Assessment of Alertness/Sedation (OAA/S) scale at 5 min intervals by a blinded observer and continuous BIS monitor. The propofol infusion was started from the rate, 3 mg/kg/hr, and subsequently varied to maintain patient comfort, sedation, stable cardiovascular and respiratory function. RESULTS: Higher infusion rates of remifentanil (0.10microgram/kg/min) produced significant respiratory depression (P < 0.05). The infused total doses of propofol were not different from each other significantly. CONCLUSIONS: This study demonstrated that administration of propofol at 3.4 +/- 1.3 mg/kg/hr with a remifentanil infusion at 0.05microgram/kg/min is the optimal dosing regimen to provide sedation, analgesia and amnesia with a low incidence of side effects, such as respiratory depression in the patients premedicated with midazolam undergoing varicose vein endovenous laser therapy.

BACKGROUND: The number of glomerulus has been considered one of the etiologic factors especially for focal segmental glomerulosclerosis. However. glomeruli are too many to calculate them correctly. Although the fractionator method has became convinced, in which they used selected sections, not whole kidney sections, with same intervals, it is also very hard to get good results. Because it is still very time-consuming and laborous work which leads to make big observers' biases. METHODS AND MATERIALS: We designed the index for glomerular number to estimate the tendency of increase or decrease of the number of it in different kidneys and which was evaluated by other conventional methods including fractionator method. Index was based upon the theory by 1\yengaard: "the number of glomerulus correlates with the weight of kidney, which is positively correlated with body weight". Calculating formula is the number of glomeruli/surface areas of cortices which contain calculated glomeruli multiplies by kidney weight/body weight. RESULTS: We applied this index to kidneys of FGS/Kist mouse and those of RFM/ Nga mouse. The former is spontaneous glomerulosclerosis modelwith heavy protein uria and renal failure and the latter is the mother side of FGS/Kist mouse but has no glomerular disease or protein uria. The number of glomerulus of FGS/Kist mouse was decreased by 30% to those of RFM/Nga mouse. CONCLUSION: This index was useful and reliable for estimating the relative glomerular number between two groups.

The macrocystic variant of serous cystadenomas of the pancreas has only recently been described. We present a case of a 40 year-old female, who presented with vague indigestion. The cyst was unilocular, and was lined by simple cuboidal, ciliated serous type epithelium. Fine needle aspiration, immunohistochemical, light microscopic, and electron microscopic studies are discussed.

Cases of over 5-level spinous process fractures are extremely rare. Thoracolumbar region of spine is superimposed on ribs; and as such additional studies such as computerized tomography are needed to diagnose fractures in this region. We report a case of 11 contiguous level thoracolumbar spinous process fractures, which has been treated conservatively.

We reviewed the clinical, electrophysiological, radiological, and histopathological findings in 25 patients with benign focal amyotrophy. There were 14 patients with upper limb type and 11 with lower limb type. 18 patients had unilateral involvement and 7 had bilateral involvement asymmetrically. The characteristics clinical features were sporadic occurrence, predominance in young males, nonprogressive course or initial progression for 1 to 3 years followed by stationary state, segmental distribution of muscle weakness and atrophy localized to one limb or both homologous limbs markedly asymmetrically, and absence of any definite sensory loss or central nervous system involvement. The electrophysiological, radiological, and muscle histopathological findings suggested chronic focal anterior horn cell disease. Although the prevalence of this disease is still unknown, the importance of recognition is being emphasized because of its common occurrence in our country and the benign prognosis.

PURPOSE: To evaluate the clinical outcome of high-dose-rate (HDR) interstitial brachytherapy (IBT) in patients with oral cavity cancer. MATERIALS AND METHODS: Sixteen patients with oral cavity cancer treated with HDR remote-control afterloading brachytherapy using 192Ir between 2001 and 2013 were analyzed retrospectively. Brachytherapy was administered in 11 patients as the primary treatment and in five patients as salvage treatment for recurrence after the initial surgery. In 12 patients, external beam radiotherapy (50-55 Gy/25 fractions) was combined with IBT of 21 Gy/7 fractions. In addition, IBT was administered as the sole treatment in three patients with a total dose of 50 Gy/10 fractions and as postoperative adjuvant treatment in one patient with a total of 35 Gy/7 fractions. RESULTS: The 5-year overall survival of the entire group was 70%. The actuarial local control rate after 3 years was 84%. All five recurrent cases after initial surgery were successfully salvaged using IBT +/- external beam radiotherapy. Two patients developed local recurrence at 3 and 5 months, respectively, after IBT. The acute complications were acceptable (< or =grade 2). Three patients developed major late complications, such as radio-osteonecrosis, in which one patient was treated by conservative therapy and two required surgical intervention. CONCLUSION: HDR IBT for oral cavity cancer was effective and acceptable in diverse clinical settings, such as in the cases of primary or salvage treatment.

Objective: The aim of the present study was to evaluate cortical hypometabolism of the F-18- fluorodeoxyglucose positron emission tomography (FDG-PET) based on a diagnostic cutoff point of the mini-mental state examination (MMSE) in de novo PD.Methods: We recruited 24 PD patients and 15 healthy controls to analyze FDG-PET. We divided the patients into two groups by the diagnostic cutoff point of MMSE for diagnosing dementia, with scores of>25 vs. < 25. FDG-PET was processed using statistical parametric mapping (SPM) 8 running on Matlab 11. Results: Patients with a MMSE < 25 presented lower score in time orientation, serial sevens, language and pentagon copying of MMSE compared to patients with a MMSE >25. Compared to healthy controls, patients with a MMSE> 25 and < 25 showed a fronto-temporo-parietal hypometabolism, which was more extended in patients with a MMSE < 25. Difference in cortical hypometabolism between patients with a MMSE >25 and < 25 was found in the right inferior parietal lobule. Conclusions: In the comparison by cutoff point of MMSE (25/24), hypometabolism in the right inferior parietal lobule suggests that the posterior cortical deficit is the main region ofde novo PD with cognitive impairment. Hypometabolism of right inferior parietal lobule is related to the damage of cerebral networkin de novo PD.
