Antithrombotic therapy is a cornerstone of acute ischemic stroke (AIS) management and secondary stroke prevention. Since the first version of the Korean Clinical Practice Guideline (CPG) for stroke was issued in 2009, significant progress has been made in antithrombotic therapy for patients with AIS, including dual antiplatelet therapy in acute minor ischemic stroke or high-risk transient ischemic stroke and early oral anticoagulation in AIS with atrial fibrillation. The evidence is widely accepted by stroke experts and has changed clinical practice. Accordingly, the CPG Committee of the Korean Stroke Society (KSS) decided to update the Korean Stroke CPG for antithrombotic therapy for AIS. The writing members of the CPG committee of the KSS reviewed recent evidence, including clinical trials and relevant literature, and revised recommendations. A total of 35 experts were invited from the KSS to reach a consensus on the revised recommendations. The current guideline update aims to assist healthcare providers in making well-informed decisions and improving the quality of acute stroke care. However, the ultimate treatment decision should be made using a holistic approach, considering the specific medical conditions of individual patients.

PURPOSE: The purpose of this study is to assess the 5-year outcome of patients considering surgery for complaint of cervical and radiating pain treated by selective nerve root block (SNRB). MATERIALS AND METHODS: Between January 2001 and December 2007, 39 cases were selected from patients who underwent SNRB before the operation and were followed-up for more than five years. The mean follow-up period was 64.3 months and the mean age was 57.7 years. The patients were divided into the operation group and the only cervical SNRB group. The groups were compared for gender, age, duration, disease, single or multi-level, and root compression rate on magnetic resonance imaging. The clinical results were analyzed using the neck disability index (NDI) and the visual analogue scale (VAS) score. RESULTS: Among the 39 cases scheduled for the operation, 20 cases (51.3%) did not proceed to the operation and 13 cases among them were treated with additional conservative treatment. The average VAS score for the operation group and the cervical SNRB group was 8.1 points and 7.5 points at the preoperative state and the pre-injection state. After surgical treatment and cervical nerve root block, the scores were 3.0 points for all. The NDI for the operation group was 11.3 points at the last follow-up. The NDI for the cervical nerve root block group was 13.6 at the last follow-up. There was no significant difference between the two groups. Shorter duration and younger age tended to show a higher operation rate. At the last follow-up, 7 cases (17.9%) after cervical SNRB had persistent symptom relief without other treatment. CONCLUSION: Cervical SNRB is considered an effective treatment for patients with cervical disease with radiating pain and who are scheduled for an operation.

PURPOSE: Although most peritrochanteric fractures in old age necessitates surgical treatment, daily life functions are still impaired after discharge. We assessed the types of peritrochanteric fracture, risk factors, and functional recovery in elderly patients who were over 65 years old. We also tried to determine factors for recovery to daily life. MATERIALS AND METHODS: From January 2006 to December 2007, among 61 patients who were over 65 years old with the possibility of 1 year follow-up, 50 patients were selected through interviews. After verifying age, sex, mode, types of fracture, and method, we analyzed daily living activities with a functional recovery index and estimated recovery of daily life functions after surgery, assuming a score increase if functional recovery was good. RESULTS: The mean age was 75.8 years, and females (31 patients, 62%) exceeded males. Slipping (27 patients, 54%) was the most common cause of fracture, and the intertrochanteric femur fracture was the most common fracture type (34, 68%). The average functional recovery index decreased 16.24% compared with the pre-operation value, having a tendency to decrease more in old age and female patients. Subtrochanteric femur fracture showed a 17.6% decrease in functional recovery index among the fracture types. CONCLUSION: In elderly patients over 65 years, the functional recovery index after peritrochanteric fracture decreased 16.24% on average compared with the preoperation state. The largest decrease was in basic life ability. The functional recovery index decreased more in old age, females, and subtrochanteric femur fracture, which indicates these factors influence functional recovery.

Inferior sinus venosus type atrial septal defect (ASD) is a rare congenital cardiac deformity that occurs between the inferior vena cava and right atrium. Inferior sinus venosus defect is difficult to diagnose through transthoracic echocardiography because of its location which is infero-posterior to the fossa ovalis. Increasing pulmonary arterial pressure and pulmonary vascular resistance in patients with sinus venosus defect usually occur earlier than other types of ASD. We report a case of 19-year-old man who presented exertional dyspnea due to inferior sinus venous type ASD with mild pulmonary hypertension. In this case, we found clues from slight diastolic flattening of interventricular septum and shortened acceleration time of right ventricular outflow tract on initial transthoracic echocardiography, leading right heart catheterization and transesophageal echocardiography to reveal this rare type of ASD.

During pregnancy profound immunologic, metabolic, endocrine, and vascular changes occur. Because of these changes, some diseases are affected by pregnancy. These diseases can aggravate or improve during pregnancy. Lymphomatoid papulosis is a continuing self-healing eruption whose lesions are clinically benign but histologically contain malignant-appearing cells. We report a case of lymphomatoid papulosis which developed in 30-year-old pregnant woman. And we discussed the possible association between lymphomatoid papulosis and pregnancy.

Primary uterine leiomyosarcomas are very rare malignant tumors and the related MR findings have been the subject of only a few case reports. We describe the MR findings of two cases of histologically confirmed primary leiomyosarcoma, correlating these pathologic findings.

PURPOSE: The purpose of this study was to establish optimal imaging acquisition conditions for the GE Advance(TM) PET imaging system by performing the acceptance tests designed by National Electrical Manufacturers Association (NEMA) protocol and General Electric Medical Systems (GEMS) test procedures. MATERIALS AND METHODS: Performance tests were carried out with 18FDG radioactivity source and phantoms by using a standard acquisition mode. Transaxial resolution and scatter fraction tests were performed with a line source and axial resolution with a point source, respectively. A cylindrical phantom made of polymethylmethacrylate (PMMA) was used to measure sensitivity, count rate losses and randoms, uniformity correction, and attenuation inserts were added to measure remaining tests. The test results were acquired in a diagnostic acquisition mode and analyzed mainly on high sensitivity mode. RESULTS: Transaxial resolution and axial resolution were measured as average of 4.65 mm and 3.98 mm at 0 cm, and 6.02 mm and 6.71 mm at 20 cm on high sensitivity mode, respectively. Average scatter fraction was 9.87%, and sensitivity was 225.8 kcps/micronCi/cc of trues. Activity at 50% deadtime was 4.6 Ci/cc, and the error of count rate correction at that activity was from 1.49% to 3.83%. Average nonuniformity for total slice was 8.37%. The accuracy of scatter correction was -0.95%. The accuracies of attenuation correction were 5.68% for air, 0.04% for water and -6.51% for polytetrafluoroethylene (PTFE). CONCLUSION: The results satisfied most acceptance criteria, indicating that the GE AdvanceTM PET system can be optimally used for clinical applications.

Lymphangioleiomyomatosis result from the proliferation of immature smooth muscle cells in the peribronchial, perivascular and perilymphatic areas of the lung. The disease primarily affects women of childbearing age, which has dyspnea, recurrent episodes of pneumothorax, pulmonary edema, chylous effusion and hemoptysis as symptoms. Most patients die from respiratory failure within 10 years after diagnosis. Definite diagnosis depends on histologic findings. We report our experience of anesthetic management for a pregnant woman with lymphangioleiomyomatosis which was confirmed with biopsy of inguinal lymph nodes.
