studio osservazionale retrospettivo della correlazione tra riduzione della massa ossea e disturbi comportamentali
Nel nostro studio sono stati esaminati due gruppi di soggetti, così suddivisi, un gruppo già con diagnosi strumentale di riduzione della massa ossea ed un gruppo controllo. Nel reclutamento del gruppo di controllo sono stati esclusi soggetti di età superiore a 65 anni, in terapia cortisonica per patologie croniche da più di sei mesi, individui che evidenziano all’anamnesi fattori che aumentano il rischio o le conseguenze delle cadute, quali disabilità, fattori ambientali, consumo di benzodiazepine, abuso di alcol o droghe, o con patologie note che possano essere responsabili di osteoporosi secondaria. La scheda di valutazione anamnestica, nei pazienti affetti da osteoporosi o osteopenia è c…
Indications and limitations of the fixator TGF “Gex-Fix” in proximal end humeral fractures
Abstract The incidence of fractures of the humerus has increased exponentially in recent years. The most used classifications for humerus fracture are morphological (Neer), biological (AO/ASIF) and descriptive (Hertel). The types of surgical treatment for humerus fracture include prosthetic replacement and synthesis using different devices, including the Tension Guide Fixator (TGF), Gex-Fix. External fixation for displaced proximal humeral fractures avoids dissection and soft tissue stripping and has been reported by some authors to be associated with higher union rates, a lower incidence of avascular necrosis, less scarring of the scapulohumeral interface, and faster rehabilitation compare…
EVALUATION OF ENVIRONMENTAL NEUTRON DOSE AT GROUND LEVEL
This work presents the results of two cycles of neutron dose rate measurements realized using an ALNOR 2202D Neutron Dose Rate Meter whose time response is acquired and analyzed through a controlled ORTEC MCS-32 acquisition card in Windows environment. The data obtained have been compared with values from previous experimental surveys and with the data provided by the worldwide main observatories. It has been also verified the influence of the fluctuations in the flux of cosmic rays during the course of a solar cycle. By comparing the realized measurements and the data provided by the cosmic ray monitoring networks it is also possible to obtain a value of ambient dose equivalent rate and ne…
Dating of Brazilian shells through electron paramagnetic resonance
In the present work we report dating procedure of these shells by using the electron paramagnetic resonance. The first step of the analysis was the definition of the optimal procedure for sample preparation. At this aim the analysis of the sample composition was carried out by X-ray fluorescence (XRF) measurements and an accurate analysis was study on the effect of the chemical etching with varying typology and concentration of acid to be used for removing the external layer of shells which are affected by alpha particles.
