A flaccid tetraparesis in Bickerstaff's brainstem encephalitis (BBE) is presumed to be a sign of overlapping Guillain-Barr$\acute{e}$ syndrome (GBS). In addition, BBE and Fisher syndrome, which are clinically similar and are both associated with the presence of the immunoglobulin G anti-GQ1b antibody, represent a specific autoimmune disease with a wide spectrum of symptoms that include ophthalmoplegia and ataxia. A 2-year-old boy presented with rapidly progressive ophthalmoplegia, ataxia, hyporeflexia, weakness of the lower extremities, and, subsequently, disturbance of consciousness. He experienced bronchitis with watery diarrhea and had laboratory evidence of recent infection with Epstein-Barr virus (EBV). He was diagnosed as having overlapping GBS and BBE associated with EBV and received treatment with a combination of immunoglobulin and methylprednisolone, as well as acyclovir, and had recovered completely after 3 months. In addition, he has not experienced any relapse over the past year. We suggest that combinations of symptoms and signs of central lesions (disturbance of consciousness) and peripheral lesions (ophthalmoplegia, facial weakness, limb weakness, and areflexia) are supportive of a diagnosis of overlapping GBS and BBE and can be helpful in achieving an early diagnosis, as well as for the administration of appropriate treatments.

Langerhans cell histiocytosis (LCH) is a rare disorder histologically characterized by the proliferation of Langerhans cells. Here we present the case of a 13-year-old girl with LCH wherein CT and MRI results led us to an initially incorrect diagnosis of meningioma. The diagnosis was corrected to LCH based on pathology findings. An intracranial mass was found mainly in the dura mater, with thickening of the surrounding dura. It appeared to be growing downward from the calvaria, pressing on underlying brain tissue, and had infiltrated the inner skull, causing a bone defect. The lesion was calcified with the typical dural tail sign. The dural origin of the lesion was verified upon surgical dissection. There are no previous reports in the literature describing LCH of dural origin presenting in young patients with typical dural tail signs and meningioma-like imaging findings. The current case report underscores the need for thorough histological and immunocytochemical examinations in LCH differential diagnosis.

Background & Objectives : Motor evoked potentials(MEPs) to magnetic trans cranial stimulation were performed to evaluate upper motor neuron involvement and relationship to lower motor neuron involvement in motor neuron disease patients. Method : MEPs were obtained in the 17 consecutive patients with motor neuron disease. These patients were divided into three group based on clinical evidence of upper and lower motor neuron involvement, bulbar symptom; amyotrophic lateral sclerosis(ALS), progressive muscular atrophy(PMA), progressive bulbar palsy(PBP). MEPs were recorded from abductor pollicis brevis and abductor hallucis muscles. Abnormal MEPs were defined by delayed central motor conduction time or absent MEP. Results : MEPs were abnormal in 64%(11/17) of patients; 100%(7/7) in ALS, 64%(4/7) in PMA, 0%(0/3) in PBP respectively. In 68 total recording muscles, 34 muscles had evidence of motor weakness and showed abnormal responses in 59%(20/34). Whereas 34 muscles with normal strength, only 3%(1/34) of muscles showed abnormal response. Conclusion : MEPs are well correlated with upper motor neuron signs in ALS and may detect masking upper motor neuron signs in PMA. The muscles with lower motor neuron sign(weakness) usually relate with abnormal MEPs reponses.

This studies was carried out to investigate a process of formation for the granulomatous lesions in the liver and the haematological variation with the lapse of time after infection of Capillaria hepatica in dogs. Twelve crossbred puppies, about 3 months of age and 2-3 kg of body weight, were administered with 2,000 Capillaria hepatica infective eggs. Every four puppies was sacrificed on 1 week, 3 weeks and 5 weeks after infection, respectively. Although no marked clinical sign was noticed, total leukocyte values were increased peak on 1 week, and then reduced gradually on 3 weeks and 5 weeks after infection. Absolute differential counts of neutrophils and lymphocytes were significantly increased on 1, 3 and 5 weeks after infection. Absolute differential counts of monocytes and eosinophils were trend to increase during the experimental periods. On grossly findings, liver congestions were observed in all infected puppies, and a few white specks were scattered under liver capsule in one puppy on 3 weeks and two puppies on 5 weeks after infection. On microscopic findings, many fresh larvae were observed in the liver tissues in one puppy on 1 week after infection. A worm was decayed and only a portion of cuticle was shown in one puppy on 3 weeks after infection. Around the central necrotic material, the layers of thick macrophages with a few giant cells and lymphocytes with fibrous connective tissues were consisted the granulomatous lesions on 5 weeks after infection.

The forms of man's costumes in Byzantine Empire were changed according to each composition of costumes. Those forms of costumes had common features of each period when costumes were included. At the same time, however, the fact that differences existed in accordance with a social position including gender, class, occupation, etc. even though in same period were showed. Analytic elements of man's costumes in Byzantine Empire were selected by important factors. This showed the meanings of position and class in that time. The kinds of analytic elements in man's outwear were various but the forms of costumes were not developed because christianity influenced the forms of clothing in the Middle Ages. As the result of synthesis, the main factor of man's costumes was a tunic in Byzantine Empire of the Middle Ages The phases of the times were reflected on the structure of man's costumes in Byzantine Empire. In particular, religious feature was emphasized, and analytic elements of costumes having meanings showed the features of the society at the Middle Ages. For example, a central analytic element of man's costume, an outer garment was a tunic style of H-silhouette that hid the body line. This was influenced by the phases of the times. Namely, the costume stands as a symbol of the times, and also is a cultural sign that reflects phases like politics, economy, religion.

In this paper, we suggest a new spatial information system called video GIS where video is used for spatial data construction and is integrated with map. We develop a prototype system of video GIS and apply it to roadside facility management. The main functions supported by the suggested system are data collection, coordinate calculation and conversion, data construction, analysis, searching, and browsing. The stereo images and corresponding position data are collected by a vehicle named 4S-Van that has GPS, IMU, and cameras. The 3-D coordinates of the objects in the images, such as road sign, signal lamp, and building, can be calculated and constructed from the collected data. The spatial objects are displayed on both image and map, and can be searched and browsed, which enables visual and realistic browsing and management of spatial objects. Compared to conventional field survey used in roadside facility management, the method enables faster, easier, and more efficient construction of spatial data. The suggested video GIS can be applied not only to roadside facility management but also to many similar projects of central or local governments that are related to GIS.
