  • Background: Neural control of airway function is through parasympathetic, sympathetic and non-adrenergic, non-cholinergic mechanisms. The autonomic nervous system controls the airway smooth muscle tone, mucociliary system, permeability and blood flow in the bronchial circulation and release of mediators from the mast cells and other inflammatory cells. The cardiovascular and respiratory autonomic efferent fibers have a common central origin, so altered cardiovascular autonomic reflexes could reflect the altered respiratory autonomic status. Therefore, we performed this study to assess the autonomic abnormality and determine the correlating factors of severity of autonomic neuropathy in patients with chronic obstructive pulmonary disease(COPD) using easily reproducible cardiovascular autonomic reflex function test. Method: The study included 20 patients with COPD and 20 healthy persons obtained on Health Promotion Center in Yeungnam university hospital. All the patients had history and clinical features of COPD as defined by the American Thoracic Society. Any patients with myocardial ischemia, cardiac arrythmia, hypertension, central or peripheral nervous system disease, diabetes mellitus, or any other diseases known to produce autonomic neuropathy, has excluded. The autonomic nervous system function tests included three tests evaluating the parasympathetic system and two tests evaluating the sympathetic system. And also all subjects were subjected to pulmonary function test and arterial blood gas analysis. Results: Autonomic dysfunction was more commonly associated with patients with COPD than healthy person The parasympathetic dysfunction was frequent in patient with COPD, but sympathetic dysfunction seemed preserved. The severity of parasympathetic dysfunction in patients with COPD was correlated with the degree of duration of disease, smoking, reductions in the value of $FEV_1$ and FVC, and arterial hypoxemia but no such correlation existed for age, type of COPD, $FEV_1$/FVC, or $PaCO_s$. Conclusion: There is high frequency of parasympathetic dysfunction associated with COPD and the parasympathetic abnormality in COPD is increased in proportion to severity of airway disease. In COPD, parasympathetic dysfunction probably does not the cause of disease, but it may be an effect of disease progression.

  • Purpose: To assess the safety and efficacy of a gemcitabine plus docetaxel regimen as a second line therapy for patients with advanced soft tissue sarcoma (STS) resistant to doxorubicin and ifosfamide-based therapy. Patients and Methods: Medical records of 64 patients with advanced STS who received gemcitabine plus docetaxel regimen as a second line treatment between May 2006 and June 2011 were examined. All patients had been previously treated with doxorubicin plus ifosfamide-based regimen at first line setting. Patients received gemcitabine 900 $mg/m^2$ on days one and eight intravenously over 90 minutes, followed by docetaxel 75 $mg/m^2$ on day eight intravenously over one hour. Cycles were repeated every 3 weeks. Results: The male-to-female ratio was 37/27 and the median age was 44 years (range; 19-67 years). Objective responses were observed in 13 (20.3 %) patients (2 CR, 11 PR) and stable disease in 21 (32.8 %). Total clinical benefit (CR+PR+SD) was observed in 34 (53.1 %). Median overall survival (OS) was 18 months (95% confidence interval (CI):12.1-23.9) and Median time to progression (TTP) was 4.8 months (95% CI: 3.6-6). A total of 243 cycles of chemotherapy were administered. The median number of cycle was 3 (range;1-11). The most common grade 3-4 hematologic toxicity was neutropenia (35.9 %). The most common nonhematologic toxicities consisted of nausea/vomiting (37.5 %), mucositis (32.8 %), peripheral neuropathy (29.7%), and fatigue (26 %). There was no toxicity-related death. Conclusion: The combination of gemcitabine plus docetaxel is an active and tolerable regimen as a second line therapy for patients with advanced soft tissue sarcoma who have failed doxorubicin and ifosfamide-based therapy.

  • Objective: To describe patterns of spontaneous reporting on adverse events following immunization (AEFIs) using the human papilloma virus (HPV) vaccine according to the Brighton Collaboration (BC) criteria. Methods: We used the Korea Adverse Event Reporting System (KAERS) database including vaccinations between 2008 and 2017. To apply BC criteria, we classified 58 BC AEFIs into World Health Organization Adverse Reaction Terminology (WHO-ART) codes. We applied MedDRA standard medical queries that were pre-defined as five BC AEFIs. Terminology mapping between MedDRA and WHO-ART terms was performed by three researchers. Descriptive statistics of individual case safety reports were analyzed according to BC applicability. Disproportionality analyses were performed on each BC AEFI and each preferred AEFI term according to the case-noncase approach; reporting odds ratio (ROR) and 95% confidence intervals (CI) were calculated. Results: Among the 30,266 reports of vaccinations between 2008 and 2017, 2,845 reports included the HPV vaccine. Of these reports, 1,511 (53.1%) included at least one BC AEFI. Reports from physicians or manufacturers included more BC AEFIs than from other reporters. Injection site reactions and fever were frequently reported in BC AEFIs; spontaneous abortion and ectopic pregnancy (ROR, 14.29 [95% CI, 4.30-47.49]) and vasculitic peripheral neuropathy (ROR, 8.57 [95% CI, 2.61-28.10]) showed the highest ROR. Among non-BC AEFIs, dizziness or myalgia were frequently reported; exposure during pregnancy (ROR, 23.95 [95% CI, 16.27-35.25]) and inappropriate schedule of administration (ROR, 22.89 [95% CI, 16.74-31.31]) showed the highest ROR. Conclusion: BC criteria would be applicable for labeled AEFIs, whereas analyzing non-BC AEFIs would be useful for detecting unlabeled AEFIs.

  • Purpose: This study aimed to assess complications and outcomes of a new approach, that is, combining short course radiotherapy (SRT), concurrent and consolidative chemotherapies, and delayed surgery. Materials and Methods: In this single arm phase II prospective clinical trial, patients with T3-4 or N+ M0 rectal adenocarcinoma were enrolled. Patients who received induction chemotherapy or previous pelvic radiotherapy were excluded. Study protocol consisted of three-dimensional conformal SRT (25 Gy in 5 fractions in 1 week) with concurrent and consolidation chemotherapies including capecitabine and oxaliplatin. Total mesorectal excision was done at least 8 weeks after the last fraction of radiotherapy. Primary outcome was complete pathologic response and secondary outcomes were treatment related complications. Results: Thirty-three patients completed the planned preoperative chemoradiation and 26 of them underwent surgery (24 low anterior resection and 2 abdominoperineal resection). Acute proctitis grades 2 and 3 were seen in 11 (33.3%) and 7 (21.2%) patients, respectively. There were no grades 3 and 4 subacute hematologic and non-hematologic (genitourinary and peripheral neuropathy) toxicities and perioperative morbidities such as anastomose leakage. Grade 2 or higher late toxicities were observed among 29.6% of the patients. Complete pathologic response was achieved in 8 (30.8%) patients who underwent surgery. The 3-year overall survival and local control rates were 65% and 94%, respectively. Conclusion: This study showed that SRT combined with concurrent and consolidation chemotherapies followed by delayed surgery is not only feasible and tolerable without significant toxicity but also, associated with promising complete pathologic response rates.

  • Purpose: Congenital insensitivity to pain with anhidrosis(CIPA) is a rare form of autosomal recessive peripheral sensory neuropathy. Patients with CIPA show loss of pain sensation, which leads to corneal ulcers and opacities, self-mutilation of the tongue and fingertips, as well as fractures with subsequent joint deformities and chronic osteomyelitis. The purpose of this report is to highlight the fact that pressure sores also are a potential complication of CIPA. Methods: This case report describes a patient presenting with pressure sores resulting from CIPA. A 5-year-old boy was referred to our department for the treatment of a $5{\times}5cm$ sacral pressure sore as a result of a hip spica cast applied for the treatment of a left hip joint dislocation. He had a history suggesting CIPA such as multiple bony fractures, mental retardation, recurrent hyperpyrexia, anhidrosis, and clubbing fingers due to oral mutilation. A microscopic examination of the sural nerve showed mainly large myelinated fibers, a few small myelinated fibers and an almost complete loss of unmyelinated fibers. After wound preparation for two weeks, the exposed bone was covered with two local advancement flaps. Results: Two weeks later, complete wound healing was achieved. A 16-month follow-up showed no recurrence. However, the patient presented with a new pressure sore on the left knee due to orthosis for the treatment of the left hip joint dislocation. Conclusion: The early diagnosis of CIPA and special care of pressure sores are important for preventing and treating pressure sores resulting from CIPA.

  • Background: We analyzed the result of the "Off-Pump" Coronary Artery Bypass grafting (OPCAB) performed to minimize inflammatory responses to cardiopulmonary bypass and myocardial ischemia during the aortic cross-clamp period. Material and Method : The preoperative diagnosis operative procedure mortality complication and postoperative course of the 50 patients who underwent OPCAB between January 1998 and September 1998 were analyzed. There were 34 males and 16 females with mean age of 60$\pm$9 years. Preoperative clinical diagnoses were unstable angina in 31(62%) stable angina in 16(32%) and clinical diagnoses were unstable angina in 31(62%) stable angina in 16(32%) and postinfarction angina in 3(6%) patients. Preoperative angiographic diagnoses were three-vessel disease in 25(50%) two-vessel disease in 5(10%) one-vessel disease in 7(14%) and left main disease in 13(26%) patients. There were elective operation in 37 cases and urgent operation in 13 cases. Result: The mean number of grafts was 3.2$\pm$1.2 per patient. Grafts used were unilateral internal thoracic artery in 43 greater saphenous vein in 37 radial artery in 7 bilateral internal thoracic arteries in 4 and right gastroepiploic artery in 2 cases Forty sequential anastomoses were performed in 18 cases. Vessels accessed were left anterior descending artery in 48 diagonal branch in 41 obtuse marginal branch in 30 right coronary artery in 24 posterior descending artery in 9 ramus intermedius in 5 and posterolateral branch in 5 anastomoses. Predischarge coronary angiography performed in 44 patients demonstrated the patency rate of 89.5%(128/143) Operative mortality was 2%(1/150) Postoperative complications were arrhythmia in 5 graft occlusion that needed reoperation in 4. perioperative myocardial infarction in 2 femoral artery thromboembolism developed after the application of IABP in 1 postoperative transient delirium in 1 peripheral compression neuropathy in 1 case. Sixteen patients(32%) were extubated at the operating room and the other patients were extubated at the mean 13$\pm$20 hours after the operation. Mean duration of stay in intensive care unit was 49$\pm$46 hours. Thirteen patients(26%) required blood transfusions perioperatively and the amount of perioperative blood transfusion was mean 0.70$\pm$1.36 pack/patient. Conclusion: OPCAB is suggested to be the ideal technique with less postoperative complication less hospitalization time and less cost.less cost.

  • This study was carried out to find out if peripheral neuropathy was resulting from exposed to pesticides in farmers. Thirty four male farmers in rural area of Chungju were selected as a study group. According to the farm type and area, the group was subdivided into two groups: the high exposed group(n=20) and the low exposed group(n=14). Nerve conduction velocity tests were done on four nerves of the dominant arm(median motor, median sensory, ulnar sensory, and ulnar motor) and three nerves of the dominant leg(peroneal motor, sural sensory, and posterior tibial motor). On the nerve conduction study, all of the results were included normal range. But comparing to reference mean values, most of results were significantly decreased(P < 0.01 by t-test). And the median motor conduction velocity and the peroneal nerve latency were significantly increased in the high exposed group than the low exposed group and reference values. But we concluded that these findings are caused by age difference not pesticide exposure. In conclusion, we cannot find any abnormality of nerve conduction velocity caused by exposure to pesticide in this study group.

  • Purpose Anti-Glutamic acid decarboxylase antibody test (GAD Ab) has been used as a predictor of type 1 diabetes. GAD Ab has also been shown to be highly potent in cerebrospinal fluid (CSF) of patients with suspected diabetic peripheral neuropathy. Recently, it has been known that clinical significance of GAD Ab using CSF is useful for the neurological disorders. However, the reference value of anti-GAD Ab has been provided only for serum. In this experiment, we estimated the reference value of anti-GAD antibody for CSF in neurological patients. Materials and Methods A total of 211 neurological patients were enrolled. Serum and CSF were analyzed by radioimmunoassay (RIA) using commercial RIA anti-GAD Ab kit (RSR, London, United Kingdom). Normal saline was used as the normal CSF control because CSF is most similar to 0.9% normal saline. Results The mean value of normal CSF control was 1.97 U/mL, and two standard deviations (2SD) was 1.44 U/mL. Based on this data, the expected reference range of CSF could be estimated from 0.54 U/mL to 3.40 U/mL Conclusion The reference range of normal CSF control using normal saline obtained with Hoffmann's method. However, there will be a need to validate the CSF reference values using human normal CSF.

  • Purpose: The mortality and the amputation rates due to vascular trauma remain high despite advanced vascular surgical techniques and supportive management. The clinical features of patients with vascular trauma have not been well studied in the Korean population. The aim of this study was to analyze the clinical characteristics of patients with vascular trauma and to develop a database and guidelines for improving the outcomes of treatment. Methods: The medical records of 37 patients with traumatic vascular injuries who had visited in an emergency center between January 2002 and December 2006 were retrospectively reviewed and statistically analyzed. Results: The mean age was 37.8 years, and the male-to-female ratio was 5.2 : 1. The mechanism of vascular trauma was penetrating in 18 patients and blunt in 19 patients. Upper extremities were most frequently injured (39.4%). The treatment methods were primary repair in 21 patients, exploratory laparotomies in 7, radiological interventions in 3, resections and graft interpositions of the pseudoaneurysm in 3, observations in 3 and a bypass graft in 1. Four out of the 37 patients died, and three of these who died had injuried abdominal vessels. Twenty-five of the patients recovered completely, four expired, seven had neuropathy in the course of treatement, one had his limb amputated, and one experienced wound necrosis. Conclusion: Peripheral vessel injuries are commonly accompanied by nerve, muscle, or tendon injuries. Patients without associated fractures or compartment syndrome had good prognosis. Although the time intervals from hospital arrival to definite treatment were the shortest among patients with blunt abdominal vascular injuries, three expired. Therefore, we offer a 'ritical pathway'to improve the outcomes of patients with blunt abdominal vascular injury.

  • The time honoured tuning fork at present widely available for examining vibration sensation is brought about the problem of great interobserver variation. To resolve t his problem, author developed a divice using electric magnet that stimulates constantly tuning fork. The perception time of vibration from tunung fork by this device was tested on the index finger of dominant hand of twenty eight subjects. It was 12.44 seconds on average and ranged from 9.47 to 17.25. Coefficient of variation of it was 16.89 percent. Correlation coefficient between test and retest after 30 minutes was 0.957(p<0.01). This device is portable. Test procedure in non-invasive, non-aversive and simple, can be performed within one minute, and does not require the skilled technician. It is felt that this device testing vibration perception time is suitable as screening tool for early detection of occupational peripheral neuropathy.
