meningitis is one of the most important causes of infant mortality and its early and proper diagnosis is of great importance, but there are currently no laboratory facilities optimized and fast in detection of meningitis pathogens. the current standard of bacterial meningitis diagnosis is microscopic examination and cerebrospinal fluid (csf) culture. this research aimed at isolating the most co...

OBJECTIVES/HYPOTHESIS Olfactory disturbances could be observed following transsphenoidal pituitary surgeries. To our knowledge, no previous comparative studies on olfactory functions after transsphenoidal endoscopic and microscopic approaches have been performed. STUDY DESIGN Prospective study comparing olfactory functions between endoscopic and microscopic transsphenoidal pituitary surgery. ...

introduction: there are several methods for evaluating microleakage in dentistry, for example dye or bacterial leakage, electro-chemical methods, radioisotope labeling and fluid filtration. the purpose of this study was to assemble the fluid filtration system for quantitative evaluation of microleakage in dental materials. materials and methods: the roots were connected to a tube filled with an...

An incidental dural tear resulting in cerebrospinal fluid (CSF) leakage is a complication of spinal surgery, with a reported incidence of between 0.3% and 16% (1, 2). The patient is likely to experience symptoms of CSF hypovolemia, including postural headache plus nausea, vomiting, pain or tightness in the neck or back, dizziness, diplopia, photophobia, tinnitus, and/or blurred vision. The usua...

many diseases are related to cerebrospinal .uid (csf) hydrodynamics. therefore, understanding the hydrodynamics of csf .ow and intracranial pressure is helpful for obtaining deeper knowledge of pathological processes and providing better treatments. furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing gen...

BACKGROUND AND PURPOSE The hyperintense acute reperfusion marker (HARM) on fluid-attenuated inversion recovery MRI is believed to be caused by gadolinium-based contrast agents crossing a disrupted blood-brain barrier. However, this hypothesis has never been directly verified in humans. METHODS In this study, we analyzed cerebrospinal fluid samples of patients with HARM on imaging regarding th...

Different techniques have been proposed to repair cerebrospinal fluid rhinorrhea. Advances in nasal surgery led to a high success rate and low morbidity for the endonasal approach. It has become the favorite route for treating cerebrospinal fluid leaks of the anterior skull base. Better results have been obtained with the improvement of rigid endoscopes and intrathecal sodium fluorescein. In a ...

The transoral approach is a direct route to the clivus. However, application of this approach is infrequent because of the risk of cerebrospinal fluid (CSF) fistula and subsequent meningitis. We report a case of clival metastatic tumor treated by staged operation without CSF leakage. A 39-year-old man was found to have a tumor in clivus extending to the intradural space. Two-staged resection th...
