Near infrared spectroscopy (NIRS) is being increasingly used for medical applications, including neurosurgical care. This preliminary report describes the use of a low cost, indigenous, non-invasive system where NIRS is used to identify superficial unilateral intracranial abnormalities. The optical density (OD) over each hemisphere was initially studied in(More)
mHealth can be defined as the application of emerging mobile communications and network technologies for health care systems. It involves the use of mobile computing, medical sensors, and communications technologies for health care. Successful implementation of mHealth makes the right information available at the right place, at the right time, and in the(More)
Lipomas are usually subcutaneous and asymptomatic. Rarely, they can occur in a deeper soft tissue plane exerting pressure on adjacent nerves. When adjacent to the neck of the radius, it can cause posterior interosseous nerve compression. In this case report, posterior interosseous nerve palsy due to an intermuscular lipoma is reported.
We present an isolated purely intranasal meningoencephalocele, presenting as a nasal polyp in an adult, which is uncommon. Based on a review of the literature, we emphasize that nasal obstruction may be the only presenting symptom of an intranasal meningoencephalocele.
A case of parasellar chondromyxofibroma with ipsilateral total internal carotid artery occlusion is presented. Its radiological appearance and its pathological characteristics are discussed and compared with previously published reports. The rare association with total internal carotid artery occlusion is reviewed.
The objective of this study is to check the feasibility of in vivo rectal dose measurement in intensity-modulated radiotherapy (IMRT) and CyberKnife treatments for carcinoma prostate. An in-house pelvis phantom made with bee's wax was used in this study. Two cylindrical bone equivalent materials were used to simulate the femur. Target and other critical(More)
Total body irradiation (TBI) is a special radiotherapy technique, administered prior to bone marrow transplantation. Due to the complex nature of the treatment setup, in vivo dosimetry for TBI is mandatory to ensure proper delivery of the intended radiation dose throughout the body. Lithium fluoride (LiF) TLD-100 chips are used for the TBI in vivo(More)
