No full textUn percorso formativo per la professione di ergonomo
No full textIl benessere, derivante dalla qualità della vita e della vita lavorativa, non proviene solo da un livello di soddisfazione individuale soggettivo o dal cosiddetto paniere minimo di beni: diviene fondamentale la possibilità accordata alla persona di esprimersi in sinergia con una serie di valori condivisi, nella consapevolezza di essere al centro di sistemi e processi, atti a tutelare la sua dignità, la sua autonomia e la sua crescita professionale. L'ergonomia entra autorevolmente in questa prospettiva culturale così attenta alla soggettività, da auspicare un'organizzazione del lavoro che pone al vertice delle strategie manageriali partecipazione e coinvolgimento, una comunicazione più fluida e diffusa e un efficace supporto sociale, senza trascurare l'ambiente fisico in cui l'uomo staziona e si muove, spendendo gran parte delle sue energie nell'interazione quotidiana con le macchine e gli strumenti di lavoro.La presente pubblicazione muove dalla urgenza di allargare, approfondire e diffondere la cultura ergonomica e fa riferimento ad un percorso formativo realizzato (Master in ergonomia) sotto gli auspici e con il concorso di differenti istituzioni (prime fra tutte la Società italiana di ergonomia/Sezione Emilia-Romagna, l'Enea ed il Centro internazionale di documentazione e studi sociologici sui problemi del lavoro del Dipartimento di Sociologia dell'Università di Bologna) ed approcci disciplinari, tutti egualmente essenziali. Ne risulta un vero e proprio percorso formativo completo e rispondente altresì alle norme europee Cree che può dunque essere proposto quale iter idealtipico di formazione di un ergonomo operante nelle odierne realtà aziendali

No full textIntracranial stenting in the treatment of wide-necked aneurysms.
No full textCoil embolization of brain aneurysms
is a well-established alternative to
surgery and the first choice treatment in
many cases. However, the embolization of
giant aneurysms (maximum diameter >10
mm) and wide-necked lesions (maximum
neck diameter > 4 mm or a dome/neck ratio
< 2) carries a high risk of coil migration.
This complication increases the risk of
thromboembolism. Endovascular techniques
commonly used to treat giant and widenecked
aneurysms include remodelling, embolization
with three-dimensional coils and
the combined use of intracranial stents with
coils or Onyx. We report our experience of
stenting associated with coil embolization to
treat wide-necked aneurysms
Retroclival hematoma
No full textA 2-year-old boy was brought to our emergency department for pain along the cervical spinal cord area, preventing normal movements of the trunk and causing difficulty walking. The pain started without any apparent precipitating factors. There was no history of trauma, although his parents reported a habit of somersaults.
He was in distress, had truncal rigidity, and refused to walk. On exam, passive movements of the lower limbs were free, deep tendon reflexes were present, and neurologic findings were normal.
Magnetic resonance imaging of the brain and spine showed an epidural hemorrhage along the clivus and ventral cervical spine (Figure), without active bleeding, excluding the need for surgery. During follow-up, we observed complete resolution of his symptoms in 3 days. Three weeks later, a follow-up magnetic resonance imaging showed complete resolution of the hematom
Extracranial self-expandible carotid stenting: a five years retrospective analysis (2000 – April 2006) in a neuroradiological centre.
No full textOver the last decades stent placement
of carotid stenosis has been introduced
as an alterntive to endoarterectomy
in symptomatic and asymptomatic stenosis.
However the major risk of stent placement
appears to be the possibility of periprocedural
embolic strokes due to release debris
during the several phases of endovascular
manipulation. For this reason new techniques
such stenting with cerebral protection
devices being already introduced. The aim
of this work is to present the outcome in our
study population, 5 years experience, that
have been received an alternative method
consisting of unprotected self-expandable
stentig, without pre and post dilatation

No full textAmyloid transthyretin-related amyloidosis (ATTR) onsets due to the extracellular multiorgan deposition of misfolded transthyretin, a serum protein that synthesizes mainly in the liver. Two different forms of the disorder have been identified to date, namely wild-type ATTR (wtATTR), previously referred to as “senile” since it was mainly diagnosed in the elderly; and an inherited ATTR (hAATR), caused by mutant transthyretin.
ATTR amyloidosis is often overlooked or misdiagnosed owing to its non-specific presentation.
Amyloid deposits can determine musculoskeletal manifestations, such as carpal tunnel syndrome (CTS), lumbar spinal canal stenosis (LSCS), or distal biceps tendon rupture (DBTR) several years before any cardiac manifestations, particularly in patients with wtATTR.
Cardiac manifestations of wtATTR (wtATTR-CA) include aortic stenosis, hypertrophic cardiomyopathy, heart failure with preserved ejection fraction, and hypertensive cardiomyopathy, although the cardiac signs and symptoms resemble those of other cardiovascular conditions of different etiology during the course of the disease [1].
We present radiological images of an 80-year-old man who had wtATTR-CA and LSCS. At the age of 65, he had had bilateral CTS. Ten years later, he began to report pain and loss of strength in the lower limbs mainly localized in the buttocks and quadriceps. Computed tomography (CT) of the spine showed a LSCS due to ligamentum flavum hypertrophy (LFH) considered to result from fibrous degeneration (Figure 1A). ATTR-CA was diagnosed (Figure 1C) four years later. Genetic investigations yielded a negative result for hATTR. Upon further investigation, spinal magnetic resonance imaging (Figures 1D, E) and a second CT scan of the spine (Figure 1B) showed significant LFH with narrowing of the spinal canal
