Posterior canal benign paroxysmal positional vertigo (PCBPPV) is the most common disease among patients who visited the st. Carollo hospital dizziness center with the head suddenly feeling rolling or rotational dizziness caused by head and body movements. Most patients showed improvements in symptoms after a single treatment. On the other hand, there are more causes requiring multiple treatments. This study examined the factors affecting the canalithiasis repositioning maneuver for symptom recovery of dizziness, which is posterior BPPV. Dizziness patients who visited the dizziness center of PCBPPV were classified. From March 2008 to November 2010, the cure rate of 165 posterior BPPVs patients was investigated. The success rate after the first, second, third, and further treatments was 57.6%, 17.6%, 10.3%, and 14.5%, respectively. The factors affecting treatment of PCBPPVs included traumatic, medical disease, cerebral infarction, small vessel disease, vestbro basilar artery insufficiency (VBI), cerebrovascular disease, brain disease, and vestibuloplasty (P<0.05). Vomiting, nausea, and syncope can be treated easily by considering the factors affecting these treatments. If the related diseases are combined with the treatment of the canalithiasis repositioning maneuver for symptom recovery of dizziness, the results will show an improvement in daily life that is free from painful dizziness.

This study was conducted to establish a comprehensive grading guideline for poultry. Guidelines for sampling size and grading were determined on the basis of survey data obtained from chicken processing house. Results were summarized as follows : For application unit, most chicken processing house preferred lot unit to farm unit. Most processing house did not want the total survey method, but selection sampling. At the beginning of the grading system, chicken processing house wanted to apply the system to a particular lots for which the company requests. There were much suggestions for grading not only portion meat, but also whole chicken. Bigger processing house preferred no. $8\~12$ to be graded. Most of large-scale processing houses used more than 81 volts for stunning and cooling tanks by soaking. For shipping chicken, Large-scale processing houses used both individual and box packing while small ones only used box packing.

Anomalous origin of right coronary artery from left sinus of valsalva is associated with sudden unexpected death, syncope, arrhythmia and myocardial ischemia. The mechanism that explains the restriction of coronary flow in the anomalous coronary artery is unclear but several surgical methods have been proposed, such as coronary artery bypass graft, coronary reimplantation, translocation of pulmonary artery, and unroofing procedure. We reported the surgical correction of the anomalous origin of right coronary artery from left sinus of valsalva between the aorta and pulmonary trunk using the unroofing procedure.

Gastric carcinoid tumor is a neoplasm that arises from enterochromaffine-like (ECL) cells in the gastric fundus. It is a rare disease that comprises less than 2% of all gastric neoplasms; however its incidence has been recently increasing. We experienced one case of gastric carcinoid tumor that was revealed to be multiple polypoid lesions. A 29-year-old female patient visited a hospital three years ago due to syncope. The blood hemoglobin was measured as 6.0 g/dl. Gastroscopy revealed multiple polypoid lesions with bleeding; therefore endoscopic clipping was performed. The polyps were diagnosed as carcinoid tumor via endoscopic biopsy. She was transferred to our hospital because of persistent iron deficiency anemia that was caused by bleeding at the gastric polyps. Gastroscopy revealed more than twenty various-sized polypoid lesions from the mid-body to the antrum. The blood hemoglobin level was 9.0g/dl. Total gastrectomy was performed under the diagnosis of gastric carcinoid tumor with bleeding. All of the gastric polyps were diagnosed as carcinoid tumors, and any metastasis to the regional lymph nodes was not found. Eighteen months after operation, the blood hemoglobin was increased to 12.8g/dl with no evidence of recurrence. Surgical resection should be considered for treating gastric carcinoid tumor with continuous bleeding.

Hypertrophic cardiomyopathy is characterized by inappropriate hypertrophy of the myocardium and is associated with various clinical presentations ranging from complete absence of symptoms to sudden, unexpected death. These are caused by dynamic obstruction of the left ventricular outflow tract and surgical approaches were initiated. But, the complete resection of hypertrophied midventricular septum is impossible by standard, transaortic approach, because of narrow vision and limited approach. And it leads to inadequate excision, will leave residual left ventricular out-flow tract obstruction or systolic anterior motion of mitral leaflet, and limit symptomatic improvement and patient's survival. We report a case of extended septal myectomy for hypertrophic cardiomyopathy of mid-septum in a child. The extended septal myectomy was performed by aortotomy and left ventricular apical incision, and made possible the complete resection of mid-ventricular septum, abnormal papillary muscles and chordae. The patient's symptom was improved and the postoperative course was uneventful.

Cyclic neutropenia is a hematologic disorder characterized by a marked decrease in the number of circulating neutrophils occurring at regular intervals and after this period, the level of neutrophils usually recovers to a normal range. The clinical symptoms of cyclic neutropenia include fever, malaise, headaches and oral findings associated with painful soft tissue ulceration where lips, tongue and gingiva are typically involved. A 4 year 1 month old boy was presented to the hospital. His chief complaint was mobility of his teeth and swollen gums. The patient had suffered from cyclic neutropenia. Clinical examination revealed evident decay on all primary teeth except for the mandibular anterior teeth and localized alveolar bone loss around mandibullar right and left first primary molars which have mobility was notable. The patient was diagnosed with multiple dental caries, gingivitis and localized periodontitis associated with cyclic neutropenia and treated based on it. The dental treatment, including regular tooth care and appropriate treatment of dental caries or gingivitis, is essential for patients suffering cyclic neutropenia. Especially, proper care at an early stage is needed for young patients to minimize the unwanted consequences for permanent teeth development.

Background: Despite the rapid expansion of percutaneous endovascular repair, open surgical repair is still recognized as an option to achieve a cure. We retrospectively analyzed over a 6 year period the surgical outcomes, the complications and the mortality-related factors for patients with abdominal aortic aneurysms. Material and Method: We analyzed 36 patients who underwent surgery for abdominal aortic aneurysms between May 2001 and June 2005, and between April 2007 and November 2009. The indications for surgery were rupture, a maximal aortic diameter > 50 mm, and medically intractable hypertension or pain. Result: The mean patient age was $69.67{\pm}6.97$ years (range: 57 to 84 years). Thirty two patients (88.9%) were males and 4 patients (11.1%) were females. Extension to the iliac artery existed in 28 patients (77.8%). Thirteen patients (36.1%) had ruptured aortic aneurysms. The mean maximal diameter of the aorta was $73.7{\pm}13.3$ mm (60 to 100 mm). Surgery was performed by a midline laparotomy and 10 patients (27.8%) underwent emergency surgery. The mortality rate was 8.3%; the mortality rate for the patients with ruptured aneurysms was 23.1 % and the mortality rate for patients with unruptured aneurysms was 0%. The postoperative complications included wound infection (3 cases), sepsis (2 cases), renal failure (2 cases) and pneumonia (1 case). Unstable vital signs, pre-operative transfusion, ruptured aneurysm, emergency surgery, comorbidity (DM and syncope) and complications (sepsis and renal failure) were the statistically significant mortality-related factors (p < 0.05). Conclusion: Emergency surgery for ruptured aortic aneurysms continues to have high mortality, but the unruptured cases are repaired with relative safety. Even though endovascular aortic repair is the trend for abdominal aortic aneurysms, an elective operation of the unruptured aneurysms could decrease the procedure's morbidity and the inconvenient for repeat evaluation with good surgical results.

Purpose : We need to reconsider booster vaccination schedule of Japanese encephalitis vaccination. To do that we evaluate the long-term immunogenicity and the incidence of adverse events with inactivated mouse brain derived Nakayama Japanese encephalitis vaccine. Methods : We tested neutalizing antibody for 311 elementary school students by plaque reduction neutralizing test(PRNT) at USAMC-AFRIMS(United States Armed Forces Research Institute of Medical Science/Department of Virology). We evaluated vaccine related adverse events by spontaneous reporting prospectively among 15,487 vaccinees who were vaccinated at public health center and 2,277 elementary school students who were immunized previously by a questionnaire and school health record. Results : According to the time interval from the last booster injection of 311 children, PRNT antibody titers gradually decreased as the interval increased; 239 mIU/mL, 188 mIU/mL, 134 mIU/mL, 49 mIU/mL each at 6, 18, 30, 42 months after the last booster injection. The seropositivity rates were 98%, 99%, 95.6%, 71.4% each at 6, 18, 30, 42 months after the last booster injection. There were 21(0.13%) cases with systemic reactions among 15,487 vaccinees who had visited the hospital by prospective passive reporting system at public health center. According to the questionnaires and school health records in elementary school students, local induration and pain were 17.4% and 14.8%, respectively. Systemic reactions including fever, vomiting, rash were reported in few cases. Conclusion : Biannual booster vaccination that has been recommended so far should not be necessary. Surveillance for adverse events with inactivated mouse brain derived Nakayama vaccine should be strengthened to better assess the number of cases and reactions associated with immunization.

Background: Coronary artery fistula is rare congenital anomaly, which account for $0.27\~0.40\%$ of all congenital heart diseases. We report the clinical observations of 45 patients with coronary artery fistula. Material and Method: We reviewed all patients presented with or without symptoms of coronary artery fistula between 1987 and 2004. Age ranged from 1 to 83 years. Twenty-six patients were female. The patients were divided into 2 groups according to the presenting symptoms. Twelve patients were in group A (asymptomatic) and 33 patients in group B (symptomatic). The most common clinical presentation in group B was angina (18) followed by dyspnea (7), atypical chest pain (5), syncope (1), fatigue (1), and palpitation (1). Twenty-five patients were associated with other cardiac diseases, which were atrial septal defect (4), coronary artery occlusive disease (6), hypertension (12), and valvular heart disease (2). Result: Patients were followed-up for a mean period of $64.8\pm62.7$ months. There was no complication related to coronary artery fistula during the follow-up period in both group. There was no mortality related to coronary artery fistula. Conclusion: In symptomatic patients, early surgical treatment is recommended considering the low perioperative morbidity. In asymptomatic patients receiving medical treatment, close follow up may be necessary.

Background: Myxoma makes up close to 50% of adult primary cardiac tumors, and this mainly occurs in the left atrium, and rarely in the right atrium or ventricle. The patients clinically present with symptoms of hemodynamic obstruction, embolization or constitutional changes. Diagnosis is currently established most appropriately with 2-D echocardiography. Surgical resection of myxoma is a safe and effective treatment, Material and Method: We reviewed our clinical experience in the diagnosis and management of 57 cases of cardiac myxoma that were seen over a 20-year period from July 1984 to July 2004. Result: The mean age of the patients was $53.5{\pm}14.0$ years (range: 12 to 76 years). There were 38 (67%) females and 19 (33%) males. The preoperative symptoms included dyspnea on exertion in 27 patients, palpitation in 4, chest pain in 9 and syncopal episode in 4. The diagnosis was made by echocardiography alone in 51, and by combination of echocardiography, CT and angiography in 6. The tumor attachment sites were the interatrial septum in 50, the mital valve annulus in 3 and the left atrial wall in cases, The tumor was excised successfully via biatriotomy in 33 (58%), left atriotomy in 15 (26%), the septal approach via right atriotomy in 3, Inverted T incision in 3 and the extended septal approach in 3. The follow-up time ranged from 1 to 229 months (mean follow-up: $84.0{\pm}71.3$ months). There were no early and late deaths and no recurrence during the follow-up period except for follow-up loss in 5 patients. Conclusion: It's concluded that excision of cardiac myxoma is curative and the long-term survival is excellent. Immediate surgical treatment was indicated because of the high risk of embolization or of sudden cardiac death. Radical tumor excision may prevent recurrences.
