Endonasal skull base surgery (see Fig. 1) has proven to be a safe, effective, and significantly less invasive surgical approach when compared to open, highly invasive techniques [1]. Nevertheless, one initial difficulty with this minimally invasive approach has been postoperative leakage of cerebrospinal fluid (CSF) [2]. While the incidence of postoperative CSF leaks are low (<1%), the potentia...

Intracranial hypotension syndrome typically occurs spontaneously or iatrogenically. It can be associated with headache, drowsy mentality and intracranial heamorrhage. Iatrogenic intracranial hypotension can occur due to dural pucture, trauma and spine surgery. Treatment may include conservative therapy and operation. We report a case of a 54-year-old man who was successfully treated with epidur...

Sakurai K, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221447 Description A 68-year-old man presented with cognitive impairment, urinary incontinence and short step gait. These symptoms, together with brain MRI finding, suggested idiopathic normal pressure hydrocephalus. After a spinal tap test to confirm the diagnosis, he suffered from postdural puncture headache. Despite an equivocal findi...

An indwelling drainage system for percutaneous drainage and radiotherapy of cystic craniopharyngiomas is described. The catheter is implanted into the cyst stereotaxically with a computed tomography-guided targeting device and connected to a Rickham reservoir. In addition to the repeated percutaneous evacuation of the cysts, this closed system enables intracavitary radiotherapy (yttrium-90) wit...

Isoelectric focusing of iron saturated serum has been established as a convenient method for showing transferrin gtycan microheterogeneity, In a clinical setting, the m~ thod is used in the detection of cerebrospinal fluid leakage, the screening for surreptitious alcohol abuse and in the diagnosis of the carbohydrate deficient glycoprotein syndrome. In normal physiological states it can also be...

introduction : the aim of this study was to examine and compare the apical sealing ability of ah26, ah plus and ah plus jet using a fluid filtration model. materials and methods : 70 single-rooted teeth were dissected from the cement-enamel junction. canals were prepared with protaper rotary system and manual k files and irrigated with 5.25% naocl and 17% edta. ten teeth were assigned as contro...

A 44-year-old Chinese man with a history of nasopharyngeal carcinoma that was treated with radiotherapy presented with fluid in the middle ear. We performed a myringotomy and subsequently made a diagnosis of cerebrospinal fluid (CSF) leakage secondary to osteoradionecrosis of the temporal bone. To the best of our knowledge, this is only the second reported case of an otogenic CSF leak resulting...

Enterobius vermicularis is a nematod of large intestine in man. Extra intestinal localization of this parasite is rare. A 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. In laboratory examination of cerebrospinal fluid (C.S.F), the appearance was red, Albu-min level was high and the glucose showed normal value. Haematoxylin and Eosin stained slides pr...
