  • Background and Purpose: To evaluate the blood flow velocity using doppler ultrasound of the carotid artery, vertebral artery, and basilar artery in stroke patients Material and Methods: To evaluate the blood flow, I measured the peak systolic velocity and mean velocity of the common carotid artery(CCA), internal carotid artery(ICA), external carotid artery (ECA). vertebral artery(VA), and basilar artery(BA) in 44 stroke patients and 15 healthy adults. To investigate the difference between ischemic stroke patients and normal healthy adults, I selected 44 ischemic stroke patients diagnosed by brain CT and brain MRI, and 15 healthy adults who did not have any symptoms of stroke, hypertension, heart disease, and diabetes melitus. Results: Peak velocity in normal adults was 50.6${\pm}$1.6cm/sec in the CCA, 67.2${\pm}$1.7cm/sec in the ICA, 62.5${\pm}$2.4cm/see in the ECA, 45.5${\pm}$1.9cm/sec VA. and 50.5${\pm}$3.5cm/sec in the BA. Mean velocity in normal adults was 26.9${\pm}$1.1cm/sec in the CCA, 43.7${\pm}$1.4cm/sec in the ICA, 26.7${\pm}$1.3cm/sec in the ECA. 31.6${\pm}$1.9cm/sec in the VA and 33.0${\pm}$2.6cm/sec in the BA. In this study, there was a significant increase in the velocity of ICA, ECA, and VA of ischemic stroke patients in comparison with normal healthy adults. And the blood flow velocity of this study in the CCA and ECA was different from other reported foreign values and the other known values in my country. Conclusion: There was a significant difference in the blood flow velocity between ischemic stroke patients and normal healthy adults. And the blood flow velocity of this study was different from other reported foreign values and the other known values in my country. Therefore, it needs more detailed studies about old aged Korean and ischemic stroke patients than previous studies.

  • Background: The common causes of lower back pain with or without leg pain includes disk disease and spinal stenosis. A definitive diagnosis is usually made by means of magnetic resonance imaging (MRI), but treatment is often difficult because the MRI findings are not consistent with the symptoms of the patient in many cases. The objective of this study was to observe the correlation between the patterns of epidurography performed in patients having lower back pain with or without leg pain and the position or severity of the pain as subjectively described by the patients. Methods: The subjects of this study were 69 outpatients with lower back pain with or without leg pain who visited our clinic and complained of predominant pain on one side. We performed caudal epidural block using an image intensifier. A mixture of the therapeutic drug and the contrast agent (10 ml) was injected to observe the contrast flow pattern. The patients who complained of predominant pain on one side were divided into the left side group and the right side group. A judgment of inconsistency was made if the contrast agent flowed to the side of the pain, while a judgment of consistency was made if the contrast agent flowed to the opposite side of the pain. The degree of the drug distribution was evaluated by counting the number of cells to which the contrast agent's flowed for evaluating the correlation between the contrasted cell and the severity of pain (one group ${\leq}$ VAS 7, the other group ${\geq}$ VAS 8) the degree of the contrast agent's contrast was evaluated by dividing and counting an image into 15 cells (the left, right, and middle sections at each level of L4, L5, S1, S2, and S3). Results: Thirty out of the 69 patients who had laterality in pain, that is, those who complained of predominant pain on one side, showed that the laterality of the pain and the contrast agent flow was consistent, while 39 patients showed that the laterality was inconsistent (P: 0.137). The evaluation of the correlation between the pain and the contrast agent flow showed that the mean number of contrasted cells was $9.0{\pm}2.2$ for the 46 patients in the group with a VAS of 7 or lower and $6.5{\pm}2.0$ for the 23 patients in the group with a VAS of 8 or higher, indicating that the former group showed a significantly greater number of contrasted cells (P < 0.001). Conclusions: This study, conducted with patients having lower back pain with or without leg pain, showed that the contrast flow pattern of caudal epidurography had a significant correlation with the severity of the pain but not with the laterality of the pain.

  • The purpose of this study was to compare the health behaviors and health indices according to whether a percutaneous coronary intervention(PCI) was performed due to chest pain. This is a secondary data analysis study of nursing information questionnaires and electronic medical records of 247 chest pain patients in a hospital from January 2010 to December 2017. The participants were divided into non-PCI and PCI groups, and the health behaviors, blood pressure, and blood lipid levels were collected at the first hospital admission and re-admission. Collected data were analyzed using SPSS 24.0. As a result of the study, smoking and lipid levels were significantly healthier than the participants in PCI group during re-hospitalization. Non-PCI group had a high risk of smoking despite the high risk of coronary artery stenosis. It was found that continuous integrated management to promote health behavior is needed. The significance of this study was to identify the importance of health behavior in patients with the risk of cardiovascular disease.

  • Objective : The aim of this study is to assess the ability of the CPT test to dignosis radiculopathy in Korean with NeuvalTM CPT database. Method : Electrical stimulation(at 2000, 250, and 5Hz) using Neurometer was applied to the 19 patients who felt back and sciatic pain with herniated intervertevral disc(HIVD) of L-spine, dignosisd by lumbar CT or MRI, and the 33 patients who felt only back or hip or leg pain without HIVD, stenosis, spondylolisthesis which causing radiculopathy. The test sites were toe1, toe3 and toe5 related to L4, L5 and S1 nerve roots. Results : The mean values of the CPT of HIVD group was stiatically lower than LBP group at toe1-250Hz, toe3-2000Hz, 250Hz and toe5-250Hz, 5Hz. The grading CPT score of HIVD group was stastically higher than LBP group at the toe3(L5). The VAS of HIVD group was stastically higher than LBP group. Conclusion : These results suggest that the CPT test can be a valuable testing for diagnosing radiculopathy in Korean. In using CPT test further study is needed for the diagnosis and evaluation of sensory nerve dysfunction in the musculoskeletal disease.

  • Background: Moyamoya disease is characterized by a progressive stenosis or occlusion of the intracranial internal carotid artery and/or the proximal portion of the anterior cerebral artery and middle cerebral artery. Whether the onset time was childhood or adulthood, the bony carotid canal diameter might be different, but reflects the size of internal carotid artery passing through the bony carotid canal. In this study, we aimed to identify the relationship between bony carotid canal diameter and clinical manifestation. Methods: 146 consecutive patients diagnosed with moyamoya disease by brain imaging studies were included. We measured the diameter of a transverse portion of bony carotid canal on bone window of a brain computed tomography(CT) image. Patients were divided into two groups, ischemic or hemorrhagic stroke according to clinical manifestation. As a result, 115 patients were included. The Suzuki stage was used as criteria for disease progression. Results: Bony carotid canal diameter was $3.6{\pm}0.5$ (right) and $3.6{\pm}0.4$ (left) in the hemorrhagic stroke group, and $3.7{\pm}0.4$ (right) and $3.6{\pm}0.4$ (left) in the ischemic stroke group. The bony carotid canal diameter of the moyamoya vessels (3.6 mm) was smaller than the diameter of non-moyamoya vessels (3.8 mm), significantly (p = 0.042). However, there was no difference in the collateral patterns and clinical manifestation in a comparison of both groups. Conclusions: In our study, there was no significant difference of clinical manifestations and collateral patterns depend on the bony carotid canal diameter in patients with moyamoya disease. These findings suggest that the clinical presentations of moyamoya disease are not related to the onset time of the disease.

  • Gastric mucosal damage by iron pills is often reported. However, iron pill aspiration is uncommon. Oxidation of the impacted iron pill causes bronchial mucosal damage that progresses to chronic bronchial inflammation, necrosis, endobronchial stenosis and rarely, perforation. We reported a case of a 92-year-old woman with chronic productive cough and significant left-sided atelectasis. Bronchoscopy revealed substantial luminal narrowing with exudative inflammation of the left main bronchus. Bronchial washing cytology showed necroinflammatory exudate and a small amount of brown material. Mucosal biopsy showed diffuse brown pigments indicative of ferrous pigments, crystal deposition, and marked tissue degeneration. After vigorous coughing, she expectorated dark sediments and her symptoms and radiological abnormalities improved. There are a few such reports worldwide; however, this was the first case reported in Korea. Careful observation of aspiration-prone patients and early detection of iron pill aspiration may prevent iron pill-induced bronchial injury.

  • Endobronchial tuberculosis is frequently associated with lymphadenopathy, bronchial stenosis, atelectasis which needs to be differentiated with other pulmonary disease. Authors are presenting 25 cases of endobronchial tuberculosis which were confirmed by bronchoscopic biopsy and AFB smear and/or culture. The study was done on patients who visited Yeungnam University Hospital from May 1983 to July 1985. The following results were obtained: 1. Of the 25 cases, 8 cases were male and 17 cases were female (male : female= 1 : 2). 32 percent of the cases was older than 60 years of age. 2. Abnormal findings on chest x-ray were seen on 22 cases of 25 cases (88%) and its most predilective site was right upper lobe.(24%). 3. Symptoms were coughing (56%), hemoptysis, hoarseness, chest pain, dyspnea and fever in orders. 4. The positive results were obtained in 73 percent of sputum AFB sme ar (11 cases of 15 cases), 60 percent of AFB culture (3 cases of 5 cases) and 58 percent of bronchoscopic biopsy (14 cases of 24 cases). 5. Complete pulmonary function test was done on 19 cases and showed normal result in 6 cases, restrictive pattern in 8 cases and small airway dysfunction in 5 cases. No case of obstructive airway disease was detected. 6. Associated disease were hypertension (2 cases), tuberculous meningitis (1 case), diabetes mellitus (1 case), and cataract (1 case). 7. The site of bronchoscopic lesion on bronchoscopic examination were as follows; 8. All 25 patients were treated with anti-tuberculosis theyapy and 6 patients were treated with additional steroid therapy because of severe respiratory symptom and showed dramatic improvement of symptom as well as lung function.

  • The treatments for spinal canal stenosis are radicular cyst removal, spine fusion, and implantation of an artificial intervertebral disc. Artificial intervertebral discs have been most widely used since the mid-2000s. The study of artificial intervertebral discs has been focused on the analysis of the axial rotation, lateral bending, the degrees of freedom of the disc, and flexion-extension of the vertebral body. The issue of fatigue failure years after the surgery has arisen as a new problem. Hence, study of artificial intervertebral discs must be focused on the fatigue failure properties and increased durability of the sliding core. A finite element model based on an in the artificial intervertebral disc (SB Charit$\acute{e}$ III) was produced, and the influence of the radius of curvature and the change in the coefficient of friction of the sliding core on the von-Mises stress and contact pressure was evaluated. Based on the results, new artificial intervertebral disc models (Models-I, -II, and -III) were proposed, and the fatigue failure behavior of the sliding core after a certain period of time was compared with the results for SB Charit$\acute{e}$ III.

  • Bronchobiliary fistula is a rare disorder consisting of an abnormal communication between the bronchial tree and the biliary duct. In Western countries, trauma, postoperative biliary stenosis, and biliary lithiasis are the predominant causative factors of bronchobiliary fistula. Bilioptysis (bile stained sputum) is a pathognomic finding for bronchobiliary fistula. To date, there are just a few reported cases of bronchobiliary fistula after sclerosis of a liver cyst. We describe the case of a 74-year-old woman who developed bronchobiliary fistula after sclerosing therapy of a liver cyst. The diagnosis was confirmed by the presence of bilioptysis and the chest and dynamic liver CT findings. The patient was successfully treated with antibiotics and percutaneous transhepatic catheter drainage.
