Functional myelography, applying spinal movements(flexion-extension) in myelography, has been frequently used for accurate diagnosis of posture-related disorders such as herniated lumbar disc or spinal stenosis. Measurements were performed on functional myelographic findings of 62 patients, and in 24 cases surgically verified herniated lumber discs were present. The object of this study was to analyze changes in position and shape of the dural sac in spinal movements and confirm the clinical importance of functional myelography. The present study demonstrated that: 1) The anterior border of the dural sac was straight with flexion, but indented at the level of intervertebral space and this indentation was less prominent at L5-S1. 2) With extension, posterior indentation of the dural sac was more prominent at the level of the intervertebral space than the body, the A-P diameter of the dural sac was narrowed at all levels of the intervertebral spaces except L5-S1, and the dural sac moved anteriorly at the level of L5-S1 and all spinal bodies. 3) In surgically verified disc patients, anterior indentation of the dural sac was persistent in both flexion and extension views, and was more exaggerated with extension, but less prominent at L5-S1. In patient at L5-S1, anterior movement of the anterior dural border at the level of surgery was much decreased.

PURPOSE: To evaluate the early clinical results of lumbar microdiscectomy using minimally invasive tubular retractor (METRx-MD system, Medtronic Sofamor Danek, Memphis, TN), and to validate the merits of minimally invasive spinal surgery. MATERIALS AND METHODS: From April, 2003 to April 2004 we retrospectively studied a consecutive series of 45 patients who underwent lumbar microdiscectomy using minimally invasive tubular retractor. In all cases, minimally invasive approach using the tubular retractor were performed with a 2 cm sized paramedian incision. The following data were collected: clinical outcomes, operative time, intraoperative blood loss, need for blood replacement, time needed before ambulation, length of hospital stay, and complications. The clinical outcomes were assessed by the modified MacNab criteria. RESULTS: Minimally invasive tubular microdiscectomy was performed in 45 patients over a 12-month period with an average follow-up of approximately 8 months. The clinical outcomes assessed by MacNab criteria were excellent in 33 patients (73%), good in 10 patients (22%). The average operative time was 63 minutes (range, 35 to 95 minutes). The average blood loss was 62 mL (range, 50 to 110 mL). None of the patients needed blood replacement. With the exception of 2 patients, all patients could walk at the day of surgery. The average hospital stay was 2.3 days. None of the patients had dural tear, wound problem, or other complications. CONCLUSION: Lumbar microdiscectomy using tubular retractor can offer a useful modality for the treatment of lumbar herniated disc with the merits of minimally invasive spinal surgery. Further long-term, randomized, prospective investigations are needed to fully evaluate the impact of this technique.

Midurethral slings are increasingly popular for the surgical treatment of stress urinary incontinence. They are relatively simple to implant and shorten operating time, hospital stay, and recovery time. Tension free vaginal tape (TVT) and Intravaginal slingplasty (IVS) mesh are both polypropylene mesh. TVT is a type I totally macroporous mesh which, because of pores larger than 75 microns, admits bacteria, macrophages, and fibroblasts into the pores. IVS is a type III mesh with microporous components which admits bacteria but not macrophages. So anterior IVS appear to be more at risk of infection or vaginal erosion than other monofilament mesh. We report our experience with a patient who underwent anterior IVS and developed erosion of the mesh through vagina, creating pelvic abscess.

Testicular granulosa cell tumor(GCT) is a rare neoplasm. We report here on an incidentally discovered testicular granulosa cell tumor in a 36-year-old man. The serum tumor markers were within the normal limits. The ultrasonographic findings revealed a mass with a heterogenous hypoechoic echotexture, including multiple variable sized cystic components. The histology on the orchiectomy specimen demonstrated a gonadal stromal tumor with granulosa cell features. Testicular granulosa cell tumor of the adult type is a very rare tumor, and there have been several isolated case reports and small serial studies described in the literature.

BACKGROUND AND OBJECTIVES: Patients with metabolic syndrome (MS) have an increased risk of cardiovascular events. However, only limited studies are available on the effect of MS on restenosis and on the clinical outcome of patients undergoing percutaneous coronary intervention (PCI). The aim of this study is to assess the role of MS in the development of restenosis, and risk of a 6-month major adverse cardiac event (MACE) and a 12-month MACE, as well as the difference of outcome between the use of bare metal stents (BMSs) and the use of drug eluting stents (DESs). SUBJECTS AND METHODS: This is a one center, retrospective study. The study population comprised 151 patients undergoing percutaneous coronary intervention (PCI) with BMSs and 200 patients undergoing PCI with DESs. The study population was classified into two groups of patients with MS and patients without MS. RESULTS: The baseline clinical characteristics were similar in the two groups (with or without MS) except for hypertension, diabetes, body mass index, triglyceride level and high-density lipoprotein level. The frequency of in-stent restenosis of the patients that were implanted with BMSs or DESs was not different between two groups, based on a 6 month follow-up quantitative coronary angiographic analysis (BMSs: 30% vs 22.2%, p= 0.352; DES: 3.3% vs 2.2%, p=0.76; for patients with and without MS, respectively). The percent of patients with a 6-month MACE for patients implanted with BMSs was not statistically different for patients with or without MS (30% vs 22.2%, p=0.352) but the percent of patients with a 12-month MACE showed a statistically significant higher level for the MS group (38.6% vs 23.5%, p=0.044). The percent of patients with a 6-month MACE for patients implanted with DESs was also not statistically different between two groups (5.8% vs 1.7%, p= 0.123). CONCLUSION: Patients with MS undergoing BMSs or DESs implantation do not show higher levels of in-stent restenosis and levels of a 6-month MACE. The number of 12-month MACEs of patients implanted with BMSs is statistically higher, but the number of 6-month MACEs of patients implanted with DESs is not different for the MS group. We conclude that MS is not risk factor of in-stent restenosis in PCI but MS may influence the long-term clinical outcome in patients undergoing PCI.

BACKGROUND: We have no information about the safety and effectiveness when we perform overdilating a sirolimuseluting stent(SES) with high pressure. In some specific animal model, the study reported overdilatation of SES with high pressure resulted in increase of restenosis. The aim of this study was to evaluate the safety and effectiveness of overdilatation of SES with high pressure. METHODS: 97 patients underwent PCI using SES between August 2003 and July 2005 were divided into two group(high pressure group, low pressure group), stents were implanted with high pressure(>18 atm) and low pressure(<12 atm). We compared between the two group of safety of stents, major adverse cardiac events(MACE), rate of restenosis, late loss. RESULTS: In high pressure group, there are more type C lesion(51% vs 38%, p<0.01). There were no significant differences between the two groups regarding MACE(12.8% vs 17.2%, p=0.78), in-stent restenosis rate(2.6 % vs 5.2%, p=0.65). There are small increasing of late loss in high pressure group, but no statistically significant difference(0.30 vs 0.15, p=0.05). CONCLUSION: Implantation of SES overdilated with high pressure is able to be performed safely to obtain wider inner lumen of stents.

"Purple toe" syndrome is an extremely rare complication of warfarin therapy. The occurrence of purple toe syndrome is characterized by a sudden appearance of purplish discoloration of toes and the sides of feet. The skin lesions usually develop 3-8 weeks after beginning anticoagulation. The pathogenesis was not clearly defined but the presence of atherosclerosis in most of patients led to suggest that the mechanism was related to cholesterol emboli from the atherosclerotic plaques and warfarin- induced bleeding into the plaques. These microemboli are commonly associated with irreversible organ dysfunction such as renal failure, distal gangrene, pancreatitis, and multifocal myocardial necrosis. Therefore purple toe syndrome may be considered as a sentinel of cholesterol crystal embolism. Once established, anticoagulation and thrombolysis are contraindicated. Necrosis and gangrenous changes may result in loss of limb and occasional mortality has been reported. We report a case of purple toe syndrome associated with acute renal failure after warfarin therapy with a review of literatures.

BACKGROUND: It is known that air borne particulates are closely related with the respiratory symptoms and peak expiratory flow (PEF) in patients with respiratory diseases. In Korea, concentrations of airborne dust and inhalable particulates are dramatically increased by the Yellow sand phenomenon, especially in springtime. OBJECTIVE: This study was performed to evaluate the effect of Yellow sand-related airborne dust on the respiratory symptoms and pulmonary function of patients with bronchial asthma. METHOD: 21 non-smoking, tree pollen non-sensitized subjects with bronchial asthma in Seoul were included in this study. For each subject, asthma and rhinoconjunctivitis symptoms were recorded by self-administered standardized questionnaire and by monitoring PEF between April and May 2000. Symptom score and diurnal variability of PEF were compared with the levels of inhalable particulate matter (PM10) checked in that time at 25 points in Seoul. RESULTS: 15 (71.4%) of the enrolled subjects successfully finished this study. There was no statistically significant relationship between the increment of Yellow sand-related PM10 and respiratory symptom or PEF variability. Of the 15 subjects, there were increased symptoms for the eye in 2 (13.3%) subjects, nose in 3 (20.0%), and sinus in 1 (6.7%), which were associated with Yellow sand-related increase of airborne dust levels. 5 (33.3%) subjects showed changes of PEF variability proportional to the change of PM10. CONCLUSION: Meteorological phenomenon related with Yellow sand has a potential risk of aggravating the upper respiratory tract symptoms and of deteriorating pulmonary functions in patients with asthma.
