Filter by:This study is investigating whether eye exercises for abducens palsy and internuclear ophthalmoplegia increase ocular range of motion in the paretic direction when performed in virtual reality under head-cancelled compared to head-active conditions.
This phase I/II trial studies the side effect and best dose of steroid therapy (prednisone or methylprednisolone) in improving symptoms of late radiation-associated lower cranial neuropathy in oropharyngeal cancer survivors. Steroid therapy with prednisone or methylprednisolone may help to improve symptoms associated with late radiation-associated lower cranial neuropathy.
Melatonin is secreted from the epiphyseal gland with a circadian rhythm and is known to be anti-inflammatory. In this study, it is planned to investigate the effect of sleep disruptions on melatonin levels and inflammation parameters in intensive care patients underwent transcranial surgery
This phase II trial studies how well gadolinium and ferumoxytol magnetic resonance imaging (MRI) work in diagnosing patients with abnormalities in the central nervous system. Diagnostic procedures, such as gadolinium and ferumoxytol MRI, may help find and diagnose abnormalities in the central nervous system.
This is a multi-center case-control study that aims to define the association between the exposure to an arbovirus infection and the development of a neurological syndrome in patients from Colombia. The study makes part of the Neurovirus Emerging in the Americas Study (NEAS) that is a collaborative effort that looks to combine the efforts of researchers, healthcare providers and patients in Colombia to establish a comprehensive registry of the clinical, radiological and laboratory profile of patients with new onset of neurological diseases associated mosquito-borne viruses, known as arboviruses.
Introduction: The skull base tumors surgery remains a challenge since numerous cranial nerves or vessels closely surround them. Recently, diffusion tensor imaging has developed with the tractography following white fibers and visualizing functional tracts. Cranial nerves tractography could allow predicting their displacement by skull base tumors that may help the surgeon to spare them along the surgery. Methods: Preoperative cerebral MRI was performed on patients who presented with skull base tumors. A 3 tesla MRI machine was used to acquire DTI sequence with specific parameters: 32 directions, slice thickness 2 mm, echo time 86 ms, repetition time 12000 ms, matrix 128x128, b-value 1000 s.mm-1. An anatomic sequence hyperT2 was overlaid as reference. Distortion was corrected by topup and eddy functions from FSL. Cranial nerves fibers were probabilistically tracked with Mrtrix3. Cranial nerves were selected according to their location around the tumor. The "radiological" expected position of the cranial nerve was compared to its "operative" real position.
Patients suffering from congenital fourth cranial nerve palsy may have misalignment of jaws as well as teeth due to head tilt in childhood.
Even at centers with very large experience, the risk of cerebrospinal fluid (CSF) leakage in surgery for microvascular decompression is reported up to 3%. Prevention of leakage is important since meningitis may follow. Also, leakage usually means longer hospital stay and increased cost. In case of detected leakage extra sutures may be applied, placement of a lumbar drain may be considered or a revision and improved closure may be attempted. With leakage in the subcutaneous tissue, but not through the skin, a local accumulation causing local symptoms may also occur. In addition to being burdensome and being associated with longer hospital stays with possible revision surgery, such complications are also very costly. The best way to reduce cost and burden, and to improve patient care, is to prevent CSF leakage. The aim of this study is to determine if prophylactic lumbar tap is beneficial for prevention of cerebrospinal fluid leakage following microvascular decompression, by comparison of surgical approaches in 3 geographical areas in the Scandinavian health system. Hypothesis: There is no difference in cerebrospinal fluid leakage between the group subject to prophylactic spinal tap versus the group without prophylactic spinal tap.
Background and Purposes: Orthognathic surgery is necessary in more than 25% of patients with cleft lip and palate (CLP) to correct skeletal discrepancy and to obtain harmonious facial esthetics in the final phase treatment. A setback of mandible by bilateral sagittal split osteotomy (BSSO) along with maxillary osteotomy is usually performed when large skeletal discrepancies or associated mandibular deformities (e.g., asymmetries, canting of the mandibular occlusal plane) are present. Although the surgical technique of BSSO is well-developed, the neurosensory disturbances of the inferior alveolar nerve (IAN) remain one of the major postoperative complications. The purpose of this study is to identify the risk factors of IAN disturbances after BSSO and in turn to help clinicians to avoid such complication and to raise the satisfaction level of patients. Design: Prospective prognosis study. Setting: Chang Gung Craniofacial Center, Taoyuan. Patients: Two hundred Taiwanese patients with nonsyndromic CLP (age, >16 for females, >18 for males), who will undergo a BSSO as a part of the correction of their dentofacial deformities Measurements: All patients will undergo subjective (e.g., questionnaire) and objective (e.g., 2-point discrimination, light touch detection, and sharp/blunt detection) neurosensory assessments before surgery, and 1, 3, 6, 12 and 24 months after surgery. Cone beam computed tomography is performed before surgery and 1 week after surgery. Peri-operative factors including type of BSSO, extent of surgical correction, extent of split and fixation screws, concomitant genioplasty or third molar extraction are assessed. Patient-related factors including age, gender, bone quality of inferior alveolar canal are recorded as well. Data Analysis: Univariate and multivariate analyses will be performed. Statistical significance is assumed for a p value of less than 0.05.
