BACKGROUND A pulse oximeter is a standard device for perioperative monitoring. It is well known that the early detection of tissue hypoxia is of great importance. It has been made easier due to a new generation pulse oximetry device from Masimo. This enables measurements of the peripheral perfusion index (PI) in real time. It has been found that volatile anaesthetics such as sevoflurane and des...

In previous issues of Endovascular Today, we have described some ongoing initiatives in the Peripheral Vascular Devices Branch intended to optimize our regulation of peripheral vascular devices. Several of these initiatives involve the establishment of standardized objective performance criteria (OPC) and control datasets for various peripheral devices, including iliac stents and endovascular g...

Previous work showed that repetitive peripheral nerve stimulation can induce plastic changes in motor cortical output. Triggering electrical stimulation of central structures from natural activity can also generate plasticity. In this study, we tested whether triggering peripheral nerve stimulation from muscle activity would likewise induce changes in motor output. We developed a wearable elect...

background implant removal is a common procedure in orthopedic surgery which can be associated with many complications such as scar formation, hematoma, nerve injury, infection, and refracture. indications for orthopedic implant removal have declined in recent years. most studies have considered orthopedic hardware removal as an unnecessary procedure in the absence of severe complications such ...

INTRODUCTION Peripheral retinal ischemia not detectable by conventional fluorescein angiography has been proposed to be a driving force for rebound edema in retinal vein occlusions. In this report, we examine the treatment of peripheral retinal ischemia with targeted retinal photocoagulation (TRP) to manage a patient's rebound edema. METHODS To assess the extent of peripheral nonperfusion, an...

despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. fifty- four male wistar rats were divided into three experimental groups (n = 18),...

malignant peripheral nerve sheath tumor (mpnst) is a rare nerve sheath tumor derived from schwann cells or pleuripotent cells of neural crest. neurogenic tumors make about 10-20% of all mediastinal tumors. incidence of mpnst is 0.001% in general population and 0.16% in patients with neurofibromatosis i (nf i). we report a case of 60 year female presenting with progressive cough and breathlessne...

introduction: peripheral odontogenic tumors are rare and there is no valid information of the frequency of them in the literature. this study aims to obtain the frequency of these tumors. materials and methods: the files of oral and maxillofacial pathology (microscopic reports and slides), faculty of dentistry, shahid beheshti university of medical sciences served as the source of the material ...
