PURPOSE: The overuse and misuse of antimicrobial agents and their resultant emergence of resistant microorganisms have made choices regarding antimicrobial therapy more difficult. We studied the changes of antibiotic sensitivity to the causative organisms of urinary tract infection(UTI) for recent 5 years in order to give some useful informations about the choice of adequate drug in the treatment of UTI. MATERIALS AND METHODS: We analysed 1191 uropathogens and their antibiotic sensitivities of the 1132 patients who admitted or visited the National Police Hospital and had more than 105cfu/ml on urine culture from January 1994 to December 1998 retrospectively. RESULTS: The common pathogenic organisms were E. coli(51.5%), staphylococcus(15.7%), pseudomonas(9.1%), klebsiella(7.5%) and enterobacter(4.0%), enterococcus(3.4%), proteus(3.1%) in order. The incidence of E. coli decreased from 50.8% in 1994 to 41.3% in 1998 but the incidence of other gram negative organisms like pseudomonas, klebsiella, enterobacter, proteus and acinetobacter increased from 24.8% in 1994 to 42.6% in 1998. In E. coli isolates(the majority of positive cultures), resistance to six antibiotics changed significantly: ampicillin(19.4% to 15.5%), piperacillin(44.1% to 32.0%), cephalothin(70.6% to 58.6%), gentamicin(62.8% to 60.2%), tobramycin(95.0% to 88.1%), and ciprofloxacin(87.6% to 76.3%). The sensitivity rates of the gram negative organisms including E. coli were very low in 1998 (ampicillin 11.6%, piperacillin 36.6%, and trimethoprim/sulfamethoxazole 49.3%). CONCLUSIONS: We think that E. coli is still the most important organism in the UTI but we shoud be concerned about the increasing incidence of other gram negative organisms like pseudomonas, klebsiella, enterobacter, proteus and acinetobacter. And prior to receiving the bacteriological report, using ampicillin, trimethoprim/sulfamethoxazole as the first choice in the treatment of UTI shoud be reconsidered.

We studied 30 patients who participated in accelerated rehabilitation program after ACL reconstruction to evaluate the effects on knee joint function prospectively. This program emphasizes early full hyperextension, early weight bearing as tolerated, and closed-chain quadriceps functional activities with rapid return to sports. Timing of the return to occupation, activity level, manual knee test, range of motion, thigh circumference, Lysholm knee score and KT-2000 arthrometer measurement were checked at the latest follow-up which is at least more than 1 year. The result were as follows: 1. The mean time for patients to return to occupation was 7.5 weeks (2 weeks-6 months). 2. Range of motion of the knee were not limited in 25 cases (83%) at 1 year after reconstruction. 3. The mean Lysholm score was 92.7. 4. The mean manual maximum KT-2000 arthrometer score was 2.0mm. The results of this study show that patients who had an ACL reconstruction with an autogenous central 1/3 patellar tendon graft and followed an accelerated rehabilitation program obtained longterm stability, achieved full range of motion, had a low complication rate, and were able to return to full sporting activities predictably.

We report a case of male infertility secondary to pituitary apoplexy, which occurred as a sequela of korean hemorrhagic fever. A 32 years old male patient with past history of korean hemorrhagic fever was studied because of infertility and erectile impotence. The size of his testicles were about 8ml in Rt. and Lt. Semen analysis, endocrinologic studies, and brain MRI demonstrated hypogonadotrophic hypogonadism due to panhypopituitarism. The patient was treated with HCG (2,000 IU) administered intramuscularly three times per week for 6 months. After the treatment, improvement of male secondary sex characteristics such as hair growth and testicle size was noted. Promotion of sexual potency and improvement of semen quality were also noted. Following the treatment, his wife conceived after 6 months.

A nephropathy following urinary tract infection is usually referred to as renal scarring. The main radiologic features are an overall reduction in the size of the kidney, with coarse scar, deformity of calyces and indentation of the surface. If adequately treated, the progressive renal scarring by urinary tract infection could be prevented. Therefore, the early radiologic detection of renal damage following urinary tact infection or vesicoureteral reflux is great importance for the evaluation of the pathogenesis of renal scarring and for the planning of the therapy. To evaluate the renal damage, we must have the normal data of the kidneys. Many reports discussed the renal size in normal children, but there are no reports in the Korean children. We estimate the renal length, width, several focal parenchymal thicknesses for renal size evaluation and segmental lumbar vertebral length at the intravenous pyelography in the normal Korean children. And the linear equations are obtained by the regression analysis between the various renal parameters and segmental vertebral length. Thereafter we make out the nomogram by the obtained equations. The renal length and width are highly correlated to the segmental lumbar vertebral length than various renal parenchymal thicknesses. These result suggest that the renal length and width are reliable parameters for normal renal size evaluation in growing kidney. And then the obtained equations and normograms might be useful in the diagnosis of parenchymal loss in early scarring and follow-up.

In this case, we describe a case of a 76-year-old male with extensive aortoiliac aneurysms treated by endovascular aneurysm repair using the sandwich technique in order to preserve left internal iliac artery perfusion. The sandwich technique refers to the deployment of multiple paralleled stent grafts into main distal and side branches in overlapping with a single proximal stent graft. The procedure was successfully performed without complications. Post-procedural CT angiography demonstrated patent stent grafts without any endoleak. The strengths and limitations of the sandwich technique need to be investigated in large-scale, long-term clinical trials.

STUDY DESIGN: Clinical and radiographic results of spine fracutre treated with pedicle screws and hooks were reviewed. OBJECTIVES: Evaluate the efficacy of tile pedicle screw and hook for thoracolumar bursting fracture. SUMMARY OF LITERATURE REVIEW: Despite of the mechanical advantage of the pedicle screw, the metal failure in short segment fusion has been reported. A biomechanical study showed additional laminar hook increased rotational strength. MATERIALS AND METHODS: Between 1994 and 1996, seventeen patients who had a Denis type B bursting fracture of the thoracolumbar spine were treated by posterior instrumentation with pedicle screws and laminar hooks and auterior interbody fusion after partial corpectomy. They have been followed for an average of 13.4 months. RESULTS: At last follow-up, radiographs showed successful fusion of the injured spinal segment in all patient. The subsidence of grafts which were used In anterior interbody fusion was an average of 0.76mm. There was a loss of 2.6 degrees on average in the correction of the kyphosis. No patients had screw breakage or loosening. CONCLUSIONS: We concluded that posterior fixation with screws and hooks, anterior decompression by partial corpectomy, and strut-grafting in patient who had a Denis type B bursting frafture of the thoracolumbar spine yielded good radiographic and functional results.

BACKGROUND AND OBJECTIVES: Percutaneous intervention has become an established technique in the treatment of peripheral arterial obstructive disease. This study was performed to evaluate the procedural success and long-term outcome of percutaneous intervention of the superficial femoral artery (SFA), and to determine the factors that influence the long-term outcome. SUBJECTS AND MEHTODS: Eighty-eight consecutive lesions, in 76 subjects (mean age 65) with chronic lower limb ischemia and SFA obstruction, diagnosed with angiography were included in this study. The angiographic success was defined as residual stenosis <30% and the clinical success as an improvement by at least one clinical category. The clinical patency was defined as an absence of symptom recurrence and target lesion revascularization during the follow up period. The predictors of the outcome were also determined. RESULTS: Balloon angioplasty only was performed in 39 lesions and thrombolysis only in 2, whereas stenting was performed in 47 lesions. Seventy four of the 88 attempts (84%) at recanalization were angiographically successful, while 73 (83%) experienced clinical improvement. The twelve month patency was 67%. Critical ischemia (versus intermittent claudication)(relative risk 4.2, p=0.020) and renal failure (relative risk 4.1, p=0.016) were independent negative predictors of the patency. CONCLUSION: Percutaneous intervention of the SFA yielded a high procedural success rate, with an acceptable long-term outcome. Symptoms of critical ischemia and renal failure were predictive of a low long-term patency.

BACKGROUND: Acute normovolemic hemodilution (ANH) is known as the easieat and most economical and the quality of autologous blood saved by it is the best of all methods of autotransfusion. To investigate the efficacy of ANH, we studied whether it could reduce the transfusion requirement in spinal surgery. METHODS: Forty patients were randomly divided into 2 groups. In the hemodilution group (n=20), 2 or 3 units of autologous blood were procured immediately before or after anesthetic induction while Ringer's lactate and pentastarch were infused to maintain normovolemia. All patients received deliberate hypotension induced by labetalol. Perioperative changes of hemoglobin, hematocrit and platelets, the transfusion requirement and the amount of postoperative drainage were compared between each group. RESULTS: Perioperative changes of hemoglobin, hematocrit and platelet showed no significant differences between each group. Less packed RBC were used in the hemodilution group (1.9 2.0 units) than in control group (5.9 6.8 units) (p<0.05). In the control group, 4 patients were transfused with fresh frozen plasma (mean 4.8 units), 3 patients with platelets (mean 13 units) and 1 patient with cryoprecipitate (10 units) while only one patient was transfused with 3 units of fresh frozen plasma in the hemodilution group. Postoperative drainage was significantly less in the hemodilution group (1,494 488 ml) than in the control group (2,476 1,730 ml). CONCLUSION: ANH seems to decrease the transfusion requirement in spinal surgery. Reduction of postoperative wound drainage appears to play an important role in that.

BACKGROUND AND OBJECTIVES: To evaluate the feasibility and the short- and mid-term follow-up outcomes of endovascular stent-graft implantation in patients with Stanford type B aortic dissection. SUBJECTS AND METHODS: Twenty-eight patients with Stanford type B aortic dissection were evaluated. An aortogram was performed immediately after the procedure and a follow-up computed tomography (CT) scan was performed within one week, between 3 and 6 months, and annually thereafter. Clinical status was also evaluated at the same time. RESULTS: Endovascular stent-graft implantation at the target site was successful in 27 patients (96.4%). There were primary endoleaks in 6 patients and one case of procedure failure owing to migration of the stent-graft; and no procedure-related mortality. The number of patients with early complications requiring treatment was 2 (2/27, 4%). Fourteen patients experienced postimplantation syndrome (14/27, 52%). The average follow-up period was 22.1+/-17.5 months. Complete resolution or thrombosis of the false lumen was achieved in 14 patients and partial thrombosis was achieved in 10 patients. Operative treatments were required in three patients due to a progressing dissection or new dissection. There were no deaths and no instances of aneurysm or aortic rupture during the follow-up period. CONCLUSION: Endovascular stent-graft implantation for Stanford type B aortic dissection is a feasible, safe, and effective treatment modality. All patients who underwent surgery had a persisting leak. Therefore, regular evaluation of the aortic dissection and management of endoleaks were crucial for a favorable outcome in endovascular stent-graft implantation for a Stanford type B aortic dissection.
