Investigating the Sensitivity of New Formulation MAGAT and NIPAM Polymer Gels in the Radiation Therapy Dosimetry.

Background: Normoxic polymer gels have been used as a three dimensional (3D) dosimeter in radiation therapy, recently. The sensitivity of these gels is important in dosimetry and their improvement can be also useful.

Objective: In this study, different modalities of gel reading were used and the structure of gel changed due to the best improvement of sensitivity.

Improvement of sensitivity of X-ray CT reading method for polymer gel in radiation therapy.

Background: Three dimensional (3D) dosimetry methods are useful for advanced radiotherapy techniques such as stereotactic radiosurgery (SRS) and high dose rate (HDR) brachytherapy. Polymer gel is one of the more reliable 3D dosimetry techniques. More studies are needed to improve the efficiency of polymer gels for their application in dosimetry.

Theophylline versus acetaminophen in the treatment of post-dural puncture headache (PDPH).

Background: Post-dural puncture headache (PDPH) is the most frequent complication of procedures associated with dural puncture for spinal anesthesia or following accidental dural puncture during epidural anesthesia. Since invasive treatments have known complications, pharmacologic management may be preferable. The aim of this study was to evaluate and compare the efficacy of theophylline and Acetaminophen in treatment of PDPH.
