The aim was to conduct a systematic review and a possible meta-analysis to determine the effect of glucocorticosteroid (GCS) on pain following root canal treatment. METHODS AND MATERIALS Scopus, MEDLINE and CENTRAL databases were searched up to 30th January 2017 with broad key word...

A total of 50 healthy volunteers aged between 18 and 54 years underwent phase-contrast cine MRI to assess cerebrospinal fluid flow characteristics in different regions of the vertebral canal. The results revealed that the cerebrospinal fluid peak flow velocity and peak flow rate in the systolic phase were significantly greater than those in the diastolic phase at the same level in the subarachn...

we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-...
