LESIONI REVERSIBILI DELL’IPPOCAMPO IN UN CASO DI AMNESIA GLOBALE TRANSITORIA
2013
SCOPO DEL LAVORO: Lo scopo di questo lavoro è documentare un caso di Amnesia Globale Transitoria (Transient Global Amnesia, TGA) in un paziente emicranico di sesso maschile di 52 anni con anamnesi negativa per epilessia, disturbi psichiatrici, traumi ed abusi di sostanze. Saranno inoltre effettuati dei cenni sull’epidemiologia e i meccanismi fisiopatologici oggi più accreditati nella letteratura scientifica più recente di questa controversa sindrome neurologica. MATERIALI E METODI: Poco dopo un forte stress emotivo il paziente non ricordava cosa avesse fatto durante il giorno e ripeteva incessantemente le stesse domande a cui erano comunque state date più volte delle risposte dai colleg…
A CASE OF A PRESACRAL MYELOLIPOMA: IMAGING FINDINGS AND DIFFERENTIAL DIAGNOSIS CHECKLIST OF OTHER PRESACRAL MASSES
2013
PURPOSE: There have been many reports describing adrenal myelolipoma but there have been only few reports of extraadrenal myelolipoma. We describe a case of an elderly woman with lower back pain due to age-related spondyloarthrosis and mild discopathy with a presacral myelolipoma as incidental finding. We also discuss about common and uncommon imaging findings of other presacral masses. METHODS: A 74 years-old woman came to our observation to perform an MRI of the lumbar spine for typical lumbar back pain. MR imaging revealed, in addition to the signs of mild scoliosis and spondylo-disc-arthrosis, a presacral mass showing heterogeneously high signal in all sequences and almost completely su…
DESCRIZIONE DI UN CASO DI LESIONE REVERSIBILE DELLO SPLENIO DEL CORPO CALLOSO IN PAZIENTE CON MONONUCLEOSI INFETTIVA DA COINFEZIONE EPSTEIN-BARR VIRU…
2013
SCOPO Presentiamo un caso di encefalite virale con lesione reversibile dello splenio del corpo calloso (SCC) in un ragazzo di 16 anni con mononucleosi infettiva da coinfezione Epstein-Barr Virus (EBV) e Citomegalovirus (CMV). MATERIALI E METODI Il paziente, a causa della comparsa improvvisa di stato confusionale, irrigidimento e movimenti involontari alternati a tremori in corso di mononucleosi infettiva, giungeva in PS, dove eseguiva una TC encefalo (Siemens SOMATOM Definition AS+ - 128 strati) in condizioni di base ed in tecnica sequenziale, che non evidenziava reperti significativi. Veniva quindi ricoverato con il sospetto di encefalite virale e, il giorno successivo, veniva sottoposto a…
SEMEIOTICA NEURORADIOLOGICA E POSSIBILI DIAGNOSI DIFFERENZIALI DI UN RARO CASO DI MIELOLIPOMA PRESACRALE
2013
SCOPO Presentiamo il caso di una paziente anziana (74aa) con tipica sintomatologia da artrosi e discopatia lombo-sacrale (rigidità e dolore alla regione lombare con tipica irradiazione ai glutei ed alla superficie posteriore di entrambi gli arti inferiori, con associata sensazione di intorpidimento) e segni di radicolopatia L4-L5-S1 all’esame obiettivo neurologico, che si presenta alla nostra attenzione per eseguire un esame RM del rachide lombo-sacrale. MATERIALI E METODI L’esame RM è stato eseguito in condizioni di base con sequenze TSE-T1, TSE-T2 e STIR-T2 secondo piani sagittali ed assiali (GE Signa HDxt 1,5T). E’ stata inoltre effettuata un’integrazione RM dopo somministrazione di md…
Presacral Myelolipoma
2014
Many reports have described adrenal myelolipomas but there have been only a few reports of extra-adrenal myelolipomas. We describe a 74-year-old woman who came to our observa- tion for MRI of the lumbar spine for typical lumbar back pain. In addition to signs of mild scoliosis and spondylo disc arthrosis, MR imaging revealed a presacral mass showing a heterogeneously high signal in all pulse sequences and almost completely suppressed on inversion recovery sequences for fat tissue. CT imaging confirmed the fatty nature of the lesion and no signs of bone involvement. These findings were most consistent with a diagnosis of a rare presacral myelolipoma as confirmed at histopathologic analysis. …
Simultaneous harvest-and-transmit ambient backscatter communications under Rayleigh fading
2019
Ambient backscatter communications is an emerging paradigm and a key enabler for pervasive connectivity of low-powered wireless devices. It is primarily beneficial in the Internet of things (IoT) and the situations where computing and connectivity capabilities expand to sensors and miniature devices that exchange data on a low power budget. The premise of the ambient backscatter communication is to build a network of devices capable of operating in a battery-free manner by means of smart networking, radio frequency (RF) energy harvesting and power management at the granularity of individual bits and instructions. Due to this innovation in communication methods, it is essential to investigat…
The sense of a patient: An ethnographic multi-site field study exploring the influence of manikins on nursing students' learning
2022
The purpose of this ethnographic study was to gain insight into the influence of full-body human-like manikins on nursing students’ learning. The research question that guided the study was: How do the presence and use of human-like manikins influence nursing students’ learning? Data were collected during 15 educational sessions, using different manikins for various activities. Applying cultural-historical activity theory, this study explored the use of manikins as a mediated activity. The study’s main result was the interplay of five categories. In the first category, manikin as an object, manikins were used to teach and learn technical skills. In the second category, manikin as a subject,…
