To obtain wider versatility and greater reach in microsurgical lumbar discectomy, modified procedure has been performed on 263 patients in 1979-1983. It consisted of a smaller midline incision, removal of lateral half of the spinous process, partial but sufficient microdrilling of the lamina, use of a modified slender Taylor retractor, flavotomy, preservation of epidural adipose-areolar tissue etc. Particularly a slender Taylor-Chung retractor offered yielding surgical opening and therefore secured free of pituitary forceps to every direction. The microsurgical results including 72 bisegmental and 8 trisegmental discectomies were compared with those of standard operations of same number performed by same surgeon in 1972-1979, for the good contrast. Mean blood loss per operation was 94 ml with the standard discectomy and 46 ml with microsurgery. Dural tear occured in 17 cases undergoing standard operation and in 3 undergoing microsugery. The mean time until return to duty was 8.6 weeks with standard, compared with 4.2 weeks. In the microsurgical group, 3 patients had postoperative discitis while 2 had in the standard. In this series, the results of microsurgery surpasses the standard in the convalescent phase. Major advantages of this modified microsurgical technique were its ability to secure the greater reach to remove disc material as much as possible and to preserve the integrity of normal tissue better.

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.

A rare case of surgically extirpated intra- and extracranial metastasis of hepatocellular carcinoma is reported. This dumb-bell shaped tumor simulated malignant meningioma on computerized tomography brain scan and cerebral angiography. Removal of the mass was successfully achieved by external carotid ligation and CUSA dissection. We suggest that, when investigating patient with suspected cranial secondaries particulary if there is a bony involvement, serum alpha-fetoprotein and hepatic ultrasound should be carried out as screening procedures.

Henoch-Shonlein(H-S) purpura, or anaphylactoid purpura is a hypersensitivity vasculitis characterized by palpable purpura usually on buttock and low extremities; arthralgia mostly polyarhtralgia in the absence of frank arthritis; gastraintestinal involvement with colicky abdominal pain, nausea, vomiting, diarrhea, constipation and bleeding; and renal involvement, manifested chiefly by hematuria and proteinuria. Gastrointestinal involvement is seen in 70 percent of pediatric patients and one third of adult patients. Any portion of the gastrointestinal tract distal to the esophagus maybe involved, but most frequently affected sites are jejunum and ileum. We report one case of H-S purpura with duodenal involvement observed in 16, male patient.

BACKGROUND: Smoking is a well-known risk factor of cancer, chronic disease, and cerebrovascular disease. Hospital admission is a good time to quit smoking but patients have little opportunity to take part in an intensive smoking cessation intervention. The purpose of this study was to identify the factors of successful smoking cessation among stroke patients who undergo an intensive cessation intervention during the hospitalization period. METHODS: Thirty-nine male smokers who were admitted with stroke were enrolled in the study. They participated in a smoking cessation intervention during hospitalization. Smoking status was followed up by telephone 3 months later. Nicotine dependence, sociodemographic factors, and other clinical characteristics were assessed. RESULTS: After 3 months post-intervention, the number of patients who stopped smoking was 27 (69.2%). In addition, there was no significant difference in nicotine dependence, sociodemographic factors, and clinical characteristics. Only the stages of readiness for smoking cessation were a significant predictor (odds ratio, 18.86; 95% confidence interval, 1.59-223.22). CONCLUSION: This study shows that a patient's willingness to quit is the most significant predictor of stopping smoking after Inpatient cessation Intervention for stroke Patients.

BACKGROUND AND OBJECTIVES: Since echocardiography became a routine diagnostic tool, pericardial effusion has become a common clinical finding. The major causes of hemorrhagic pericardial effusion are malignancy and tuberculosis. However, it was unknown to the use of biochemical analysis of pericardial fluid and serum, for differentiation of malignancy from tuberculosis. To evaluate this, we investigated the biochemical analysis of pericardial fluid and serum in relation to the causes of pericardial tamponade. SUBJECTS AND METHODS: 46 patients who were admitted to Pusan National University Hospital from January 1, 1995, to April 30, 2002, and underwent both a pericardiocentesis and a pericardiostomy for the relif of cardiac tamponade, were included in this study. the pericardial fluid was routinely analyzed for the following: gross appearance, cell count, glucose, total protein(P), lactate dehydrogenase(LDH), cytology, gram stain, cultures for bacteria and mycobacterium, pericardial fluid to serum ratios of total protein and lactate dehydrogenase,(p/s TP, p/s LDH, respectively). RESULTS: f the 46 patients who underwent both pericardiocentesis and pericardiostomy, for the relief of cardiac tamponade, 33 patients(71.7%) had hemorrhagic pericardial effusion. The common causes of hemorrhagic pericardial effusion were malignancy(51.5%) and tuberculosis(33.3%) but, those of nonhemorrhagic pericardial effusion were idiopathic (38.5%). Cell counts were higher in hemorrhagic than nonhemorrhagic group(p=.029). Serum LDH(sLDH) was higher in malignant than tuberculous group(p=.001) but, serum total protein(sTP) was higher in tuberculous group(p=.004). Compared malignant group with tuberculosis group in patients with hemorrhagic pericardial effusion, p/s ratio of LDH and sTP were higher in tuberculous group (p=.029, p=.017), but sLDH was higher in malignant group(p=0.002). CONCLUSION: It is difficult to differentiate tuberculosis from malignancy only on the basis of the biochemical analysis of pericardial fluid in hemorrhagic pericardial effusion. However, the analysis of both pericardial fluid and serum may make it possible to evaluate the cause of pericardial effusion.

PURPOSE: To evaluate the penetration capability of Levofloxacin and Ciprofloxacin into prostatic tissue, we analysed the concentration of each drug in serum and prostatic tissue simultaneously after oral administration. MATERIALS AND METHODS: Eleven patients with benign prostatic hyperplasia treated with transurethral resection of the prostate were entered in this study. A single dose of 200mg Levofloxacin(LVFX) and 250mg ciprofloxacin(CPFX) were administered orally. Two hours after administration, blood and prostatic tissue samples were taken during operation. Concentration of each drug in serum and prostatic tissue was measured simultaneously by high performance liquid chromatography. RESULTS: The mean concentration of LVFX in serum was 1.970 +/- 0.759 microgram/ml, which was significantly higher than that of CPFX(0.903 +/- 0.291 microgram /ml)(p < 0.05). The mean concentration of LVFX in prostatic tissue(2.256 +/- 1.121 microgram/g), however, was not significantly different from that of CPFX(2.395 +/- 0.846 microgram/g). And the concentration ratio(tissue/serum concentration) of LVFX and CPFX was 1.16 and 2.76, respectively. CONCLUSIONS: These results show that LVFX is not superior to CPFX with respect to the penetration capability into prostatic tissue. Considering that the concentration of LVFX in prostatic tissue was higher than that in serum and not different from that of CPH, LVFX may be another potential effective agent in treating patients with chronic bacterial prostatitis.

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 AND OBJECTIVES: An early invasive strategy with coronary angiography and revascularization is currently the recommended treatment for patients at high risk with an acute non-ST-segment elevation myocardial infarction (NSTEMI). In this early invasive strategy, percutaneous coronary intervention (PCI) is generally recommended within 48 hours, but there is little data on earlier intervention in intermediate risk patients. SUBJECTS AND METHODS: We studied retrospectively the past medical records of 118 patients at intermediate risk that were admitted at Pusan National University Hospital and were stratified by the time interval from chest pain onset to PCI (Group I: <24 hr; Group II: 24-48 h; Group III: >48 h). Clinical outcomes were evaluated in terms of in-hospital and 12 months follow-up of a major adverse cardiac event (MACE). RESULTS: Baseline characteristics were not different statistically among the three groups, except for the use of tirofiban. There were no in-hospital deaths or myocardial infarctions (MI) in Group I and Group II patients, but there were three cases of in-hospital deaths in Group III patients. The incidence of a 12-month MACE was 0% in Group I patients, 6.7% (one revascularization) in Group II patients and 17.1% (3 deaths, 3 MIs, 7 revascularizations) in Group III patients (p=0.043). CONCLUSION: In acute NSTEMI, the incidence of a 12-month MACE was lower in the intermediate risk group when PCI was performed in the early period. Early PCI could be recommended in acute NSTEMI on the basis of the status of individual patients.

In surgeries that require the implantation of a pacemaker, the endocardial pacemaker leads are introduced into the cardiac chambers through subclavian or axillary venous catheterization or cephalic vein cutdown. The drawback of this type of surgery is scarring of the pectoral area, which can be a serious cosmetic problem especially for young women. In this study, we report on 2 cases where a permanent pacemaker in two young women with symptomatic bradycardia was implanted using a transaxillary incision. Both patients successfully recovered with no complications and were asymptomatic for more than 17 months after the procedure. Therefore, we found that implantation of a pacemaker via transaxillary incision provided excellent cosmetic results and should be considered in young women that require this type of surgery.
