Recently fire blight occurred in the Republic of Korea and eradication program for the disease has been executed since then. Specificity and detection sensitivity of the 2 antibody-based diagnostic strips to Korean isolates of Erwinia amylovora (Ea) and their application for on-site diagnosis were evaluated in this study. Ea AgriStrip, a commercial diagnostic kit, and EB strip, developed in this study, reacted positively to the all tested Korean Ea strains and also to most of Erwinia pyrifoliae (Ep) strains causing black shoot blight. They reacted negatively to all Pusedomonas syringae pv. syringae (Pss) strains that cause shoot blight on apple. Detection sensitivity was similar between the 2 strips. For on-site diagnosis, the two strips reacted positively only to the extractions of the fire-blighted samples on all fire blight occurred orchards except one orchard at which on-site diagnosis was carried out at winter time. In addition, they reacted positively to the black-shoot blighted extractions from the black shoot blight occurred apple orchard. These results suggest that both EB strip and Ea AgriStrip would be useful for on-site diagnosis of fire blight in Korea.

Trigeminal neuralgia is defined as "a sudden, usually unilateral, brief stabbing recurrent pain in the distribution of one or more branches of the fifth cranial nerve" by the International Association for the Study of Pain(IASP). Trigeminal neuralgia is classified as an idiopathic trigeminal neuralgia with no apparent cause and a symptomatic trigeminal neuralgia which is caused by a structural lesion such as brain tumor. Over 80% of the tumors are meningioma, acoustic neuroma, and epidermoid tumors. Symptomatic trigeminal neuralgia can not be excluded even if old-aged patient does not have abnormal neurologic sign and symptom, and good response to pharmacotherapy. Therefore, initial examinations such as MRI or CT are essential to exclude symptomatic trigeminal neuralgia. When compared with CT, MRI, especially gadolinium enhanced MRI, has an increased sensitivity in the detection of intracranial lesions. The most effective medical treatment of trigeminal neuralgia is carbamazepine. The most common side effects of carbamazepine include drowsiness, dizziness, unsteadiness, nausea, anorexia. Hepatotoxicity, bone marrow depression are the most feared side effect of carbamazepine therapy but occurs rarely. It require periodic complete blood cell counts as well as hepatic and renal function tests. It has been recommended that complete blood cell counts is done every 2 weeks for the first 2months and then quaterly thereafter. Oxcarbazepine can be used if neutropenia occurs.

CT guided percutaneous fine-needle aspiration (FNA) of the liver for both cytologic and histologic examination has great value in diagnosing liver malignancy. From March, 1986 to April, 1990, 62 patients with the clinical impression of liver malignancy underwent CT guided percutaneous FNA biopsy. Of these, 43 cases were reviewed for this study, 19 were reported to be liver cell carcinoma, 2 were adenocarcinoma, 11 were reported as anaplastic cell present, and the rest (11 cases) were negative (9) or necrotic (2). Among the 11 cases of the last group, 9 were diagnosed as liver cell carcinoma and 2 were necrotic histologically. Retrospective review, in order to clarify the cause of cytologic diagnostic error, of both cytologic and histologic slides of all cases showed discordance of 23% between these diagnoses and sensitivity is 93.9% and specificity is 90.9%. The reasons were as follows ; 1) the lack of awareness of tumor cells of well differentiated liver cell carcinoma (4 cases), 2) missed tumor cells due to too scanty cellularity (1 case), 3) improper smear (2 cases) and no tumor cell In the cytologic smears (3 cases). In such cases, at the initiation of FNA, a correct diagnosis of liver malignancy could only be made by a combination of cytologic and histologic examinations. However after three years' experience we can conclude that cytomorphologic features of liver cell carcinoma are sufficiently distinctive from other liver malignancies to be diagnostic.

Upper canine is described as 'cornerstone' of maxilla, and its importance is implicated by long root and good alveolar support. The incidence of impaction of upper canine is the second most frequent next to the third molar because it takes a long period of time to develop, and has a complicated path of eruption, and erupts lately. Generally, the patient who has a palatally impacted canine visit the clinic primarily due to a missing of canine after 12-13 years old. Palatally impacted canine is different from labially impacted canine in its cause and treatment process. It is due to malposition or anomalous lateral incisor rather than arch length deficiency. Once the impaction is identified, the first stage of the treatment is to localiz the lesion by radiographic examinations or others and according to severity, orthodontic traction, or transplantation should be considered, and comprehensive diagnosis and treatment plan of malocclusion should be estsblished. Properly managed impacted canine can provide funtion and esthetic through proper diagnosis and treatment of extraction of canine is not indicated.

Lysosomal storage diseases (LSDs) are a group of rare inherited metabolic disorders caused by the deficiency of specific lysosomal enzymes and subsequent accumulation of substrates. Enzyme deficiency leads to progressive intra-lysosomal accumulation of the incompletely degraded substances, which cause dysfunction and destruction of the cell and eventually multiple organ damage. Patients have a broad spectrum of clinical phenotypes which are generally not specific for some LSDs, leading to missed or delayed diagnosis. Due to the availability of treatment including enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation for some LSDs, early diagnosis is important. ERT products have been approved with optimal outcomes for some LSDs in the recent decades, including Gaucher, Fabry, mucopolysaccharidosis (MPS) I, Pompe, MPS VI, MPS II, and MPS IVA diseases. ERT can stabilize the clinical condition, prevent disease progression, and improve the long-term outcome of these diseases, especially if started prior to irreversible organ damage. Based on the availability of therapy and suitable screening methods in the recent years, some LSDs, including Pompe, Fabry, Gaucher, MPS I, MPS II, and MPS VI diseases have been incorporated into nationwide newborn screening panels in Taiwan.

Abdominal epilepsy is accepted as unusual cause of abdominal pain in children and young adolescents. Although its abdominal symptoms may be similar to those of the irritable bowel syndrome, it may be distinguished from the latter condition by the presence of the altered consciousness during some of attacks, EEG abnormalities, and a good response to anticonvulsant medication. The diagnosis of abdominal epilepsy came into vogue in the 1950s and 1960s as an explanation for childhood abdominal complaints. More recently, it has been recognized that isolated vomiting without loss of consciousness or other more common paroxysmal symtoms is rarely attributable to abdominal epilepsy. We report 4 cases of abdominal epilepsy, whose ages ranged from 8 to 11 years, with paroxysmal abdominal pain or vomiting consistent with a diagnosis of abdominal epilepsy.

Purpose: The masserteric space is an important tissue compartment of the face, but a disease in it is difficult to diagnose and treat. The submasseteric abscess is located between the masseter muscle and mandibular ramus with different appearances such as sepsis, infection, or tumor. Especially the common misdiagnosis of submasseteric abscess is acute or chronic parotitis. The purpose of this report is to pay special attention to the possible diagnosis of submasseteric abscess for the symptoms of unilateral cheek swelling and tenderness that accompany marked trismus. Methods: A 11-year-old boy came to our hospital because of facial swelling, tenderness, and trismus in a history of left cheek swelling and toothache. We diagnosed his case as submasseteric abscess by CT scan and surgical intervention was performed. Under general anesthesia, the abscess was opened by the intraoral incision and considerably massive pus was drained. Results: Swelling, tenderness, and trismus became to subside during postoperative 10 days and general condition and vital signs became stable. After 6 months, CT scan showed that both masseteric muscles were symmetric and there was no periosteal reaction of the mandible. Conclusion: In conclusion, submasseteric abscess is a rare infection with the symptoms of cheek tenderness and marked trismus. A detailed medical history and clinical examination of a patient as well as computed tomography(CT) are important tools in the accurate diagnosis and efficient treatment of the submasseteric abscess. Adequate drainage, removal of cause, and antibiotic infusion are the management of choice.

Automobile is in charge of most transportation system in modern urban city. However, in fact, cause of problem of road state, environment, and the other reasons, urban transit system is using as Mass Transit nowadays. Nevertheless Urban transit system is considering many kind of safety fact of that system which is increasing continuously nowadays, it occurs various train accident. This paper describes 3D Dimensional Measurement(EDM testing) and tensile testing results of carbody structure for crashed EMU(Electric Multiple Units). Tensile tests were performed on two different types of specimens in order to evaluate the strength changes before and after damages, obtained from plastic deformed area and nondeformed region of the crashed EMU. And Structural analysis of EMU was performed for the criteria of safety assessment. Structural analysis using commercial I-DEAS software provided important information on the stress distribution and load transfer mechanisms as well as the amount of damages during rolling stock crash. The testing results have been used to provide the critical information for the criteria of safety diagnosis.

Epiploic appendagitis is an inflammation of the epiploic appendage in which the small sacs projecting from the serosal layer of the colon are positioned longitudinally from the caecum to the rectosigmoid area. Epiploic appendagitis is rare and self-limiting; however, it can cause sudden abdominal pain in children. Epiploic appendagitis does not typically accompany other gastrointestinal diseases. Here, we report on a healthy eight-year-old girl who presented with abdominal pain, fever, vomiting, and diarrhea. Based on these symptoms, she was diagnosed with acute gastroenteritis, but epiploic appendagitis in the ascending colon was revealed in contrast computed tomography (CT). The patient was treated successfully with conservative management. CT is beneficial in diagnosis and further assessment of epiploic appendagitis. Pediatricians need to be aware of this self-limiting disease and consider it as a possible alternate diagnosis in cases of acute abdominal pain.

Ethylene glycol poisoning can cause profound morbidity and is almost universally fatal if untreated. Central nervous system depression, pulmonary edema, and acute oligulic renal failure with crystalluria are among the most commonly encountered complication of ingestion. Ingestion of ethylene glycol may be an important contributor in patients with metabolic acidosis and subsequent renal failure. The diagnosis of ethylene glycol poisoning is based on nonspecific clinical symptoms and signs and indirect and direct laboratory measurement of ethylene glycol. As a result, diagnosis and treatment sometimes can be delayed. We describe 52-year-old man who visited to emergency department with mental change of unknown origin. The patient has high anion gap metabolic acidosis and renal failure due to ingestion of antifreeze that contained ethylene glycol. We used hemodialysis for elimination technique. The patient was discharged with minimal complication.
