Ferrous sulphate dosemet'er solution in plastic irradiation vessels was posted to three radiotherapy centres for 6oCo irradiation, and taken to a fourth centre for 4 JIv x-ray irradiation, as an experimental trial for the future dosimetry of high energy electron therapy beams. The ferrous sulphate was returned for measurement, and doses calculated from the results have been compared with estimates based on ionization measurements with Farmer-Baldwin dosemeters calibrated at the National Physical Laboratory. FeSO, and ionization dose estimates have not differed by more than 2 % at any centre, and the precision of a short series of measurements a t a single centre is better than l?(,. The irradiation vessels are non-breakahle, cheap, and have been shown to have no adverse effect on solution response.
Background: Length-Dependent Sensorimotor Peripheral Neuropathy (LDSMPN) affects the longest nerve fi bers in the body. Less well-appreciated, and absent from the current literature, is that LDSMPN affecting thoracic segments gives rise to ventral abdominal sensory loss on clinical exam. Methods: Consecutive patients seen for LDSMPN (n=30) were evaluated prospectively for the presence or absence of ventral abdominal sensory loss. Demographic variables, symptoms, quantitative neurologic fi ndings (Neuropathy Impairment Score [NIS]) and fi nal diagnosis were examined using descriptive statistics. Background: Mononeuritis multiplex is a painful, asymmetrical peripheral neuropathy involving motor and sensory nerves. This neurological condition is classically associated with systemic diseases such as connective tissue disorders, vasculitis, hematologic diseases including cryoglobulinaemia and amyloidosis. It has also been reported infrequently as a paraneoplastic or post infectious disorder. Methods: Case report Results: We are reporting a case of a 35-yearold man who presented with mononeuritis multiplex following an infectious mononucleosis associated with a mixed cryoglobulinemia. He was treated with IVIG, IV pulse steroid and a prednisone taper over 7 months. Later on, he had a nerve transfer from FCR (fl exor carpi radialis) to ECRB (extensor carpi radialis brevis) and PIN (posterior interosseous nerve) due to complete denervation of the PIN without evidence of spontaneous recovery. Conclusions: Acute EBV infection should be suspected in the setting of mononeuritis multiplex. This is the fi rst reported case of nerve transfer for this type of nerve injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
