Fibrous dysplasia is a benign bone disorder that most commonly affects craniofacial bones; one or multiple adjacent bones can be involved which can severely deform the skull base. Cerebrospinal fluid leakage in combination with extensive craniofacial fibrous dysplasia is an extremely rare condition that leads to complicated skull base deformation and possible neurovascular structure impingement...

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...

CSF fistula/CSF leak is a pathological disorder that spans all ages. the primary clinical characteristic of this disorder is abnormal leakage of cerebrospinal fluid (CSF), from CSF containing compartments of the central nervous system (CNS) to the around space due to abnormal defect of the Dura matter and the skull [1], which typically appears as a clear watery leakage from nose (rhinorrhea) or...

OBJECTIVES To evaluate the sealing ability of five root canal sealers, including two experimental cements (MBP and MTA-Obtura) using the fluid filtration method. MATERIAL AND METHODS Teeth were divided into 5 study groups: G1-AH Plus; G2-Acroseal; G3Sealapex; G4-MBP; G5-MTA-Obtura; and two controls. Chemical-mechanical preparation was performed with ProFile rotary nickel-titanium instruments ...

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...

PURPOSE To evaluate spectral-domain optical coherence tomography (SD-OCT) findings that predict angiographic leakage in choroidal neovascularization (CNV). METHODS SD-OCT and fluorescein angiography (FA) images of 93 eyes of 93 patients were retrospectively analyzed. All patients were previously treated with anti-vascular endothelial growth factor agents for CNV from age-related macular degen...

We herein report that the adsorption/desorption of citrate-capped gold nanoparticles (AuNPs) transiently causes leakage in fluid phase DOPC liposomes, while the liposomes do not leak with AuNPs capped with mercaptopropionic acid (MPA). Leakage also fails to occur for gel phase DPPC liposomes. Citrate-capped (but not MPA-capped) AuNPs raise the phase transition temperature of DPPC. We conclude t...
