UNLABELLED The search for new instruments to promote an appropriate cervical preparation has led to the development of new rotary instruments such as TripleGates. However, to the best of the authors' knowledge, there is no study evaluating TripleGates effect on the "risk zone" of mandibular molars. OBJECTIVES The aim of this study was to evaluate the effects of a crown-down sequence of Gates-...

Parotid lymphoepithelial carcinoma is extremely rare, and makes up only 0.4% of cases among the anaplastic variant salivary gland carcinoma. We present a 63-year-old man who had progressive enlarging right neck swelling for one year. He sought treatment in another centre underwent superficial parotidectomy, following an ultrasound assessment mass that was suggestive benign parotid tumour. There...

Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result ...

We examined three intervention methods for their efficacy in preventing aspiration in 25 patients with Parkinson's disease (PD) and 23 patients with degenerative cerebellar ataxia (CA). On videofluoroscopic examination. 13 patients with PD (52%) and 7 patients with CA (30.4%) showed aspiration. In all PD patients and 5 patients with CA, no aspiration was observed after changing the food form. W...

High-resolution surface-coil MR imaging reveals intricate anatomic detail of the cervical spinal canal and its neurovascular contents. Appreciation of the normal neurovascular anatomy provides a scientific foundation for the detection of disease. Sagittal, axial, and oblique MR images of normal subjects were correlated with comparable anatomic sections obtained with a cryomicrotome whole-organ ...

Ossification of the posterior longitudinal ligament in the cervical region is generally regarded as a rare disease, though a Japanese series of 185 cases has been reported. The main symptoms arise from a myelopathy, the degree of which varies from moderate to severe, due to stenosis of the spinal canal. In order to clarify the relationship between the severity of symptoms and the cross-sectiona...

The use of intra-amniotic hypertonic saline for termination of pregnancy in second trimester has become fairly established. Whereas, the literature deal with the method of infusion through the abdominal route, very few are on the approach through vaginal route. Fuchs (1967) preferred vaginal instead of abdominal route between thirteenth to twentieth weeks of pregnancy. He has described the tech...

919 Scientific abstract: Chronic pain Utility of Digital Subtraction Angiography in Cervical Transforaminal Epidural Steroid Injections: Does Digital Subtraction Improve Safety Over Live Fluoroscopy? Andrew Rubens, Carlos A. Pino, Clarence Ivie The University of Vermont Medical Center Introduction Cervical transforaminal epidural steroid injections (CTFESI) have been used for many years in the ...

Metrizamide is useful for evaluating both posterior fossa and the cervical spinal canal [1, 2]. Because the contrast material is diluted by spinal fluid enroute from the lumbar region to the cervical spinal canal, the C1-C2 puncture technique has been advocated as the most suitable approach for instillation of contrast material [3]. The procedure is safe and without great technical difficulties...

We report a very rare case of cervical compressive myelopathy by an anomalous bilateral vertebral artery (VA) entering the spinal canal at the C1 level and compressing the spinal cord. A 70-year-old woman had been suffering from progressive gait disturbance. Magnetic resonance imaging revealed that a bilateral VA at the V4 segment had abnormal courses and caused compression to the high cervical...
