A 49-year-old man with 10 years of intranasal cocaine use presented with dysphagia. Neurologic examination demonstrated bilateral sixth nerve palsies. Brain MRI showed erosion of the sphenoid sinus walls and a defect in the skull base; the resulting path between the nasal cavity and brainstem permitted rhomboencephalitis and clival osteomyelitis (figure 1). Clival cultures grew methicillin-resi...

BACKGROUND A new technique for visualisation of the vitreous base is described. It uses a standard lightpipe for scleral indentation and transillumination. Visualisation of the vitreous using low light levels can be achieved by enhancing the Tyndall effect. DISCUSSION Perfluorocarbon liquid (PFCL) is used to confine the aqueous environment to the anterior vitreous cavity and triamcinolone is ...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...

Mucoceles are one of the most common benign soft tissue masses of the oral cavity. When they occur in the tongue, the ventral surface is the usual location. Mucoceles at the base of the tongue are extremely rare and must be differentiated from intralingual thyroglossal duct cysts. We present a case of a mucocele on the base of the tongue, which was incidentally found on a cervical spinal magnet...

The purpose of this study was to determine the effect of cavity depth, ceramic thickness, and resin bases with different elastic modulus on von Mises stress patterns of ceramic inlays. Tridimensional geometric models were developed with SolidWorks image software. The differences between the models were: depth of pulpal wall, ceramic thickness, and presence of composite bases with different thic...

BACKGROUND Prenatal tongue development may affect oral-craniofacial structures, but this muscular organ has rarely been investigated. METHODS In order to document the physiology of prenatal tongue growth, we histologically examined the facial and cranial base structures of 56 embryos and 106 fetuses. RESULTS In Streeter's stages 13-14 (fertilization age [FA], 28 to 32 days), the tongue prot...

Abstract In order to cut off the connection between mobile terminal and communication base stations or Wi-Fi, it is necessary improve electromagnetic shielding efficiency of phone cabinet. This paper analyzes resonant characteristics cabinets. The test method has been introduced. Through Maxwell wave equation boundary conditions, cavity frequency every small drawer on cabinet derived, rectangul...
