INSIDIE DIAGNOSTICHE DELLA TROMBOSI VENOSA CEREBRALE: STORIA DI UN CASO CLINICO

2018

Introduzione: la trombosi venosa cerebrale (TVC) è una condizione rara, le manifestazioni sono spesso elusive, i primi reperti radiologici non d‘immediato riscontro e quindi trascurabili. La prognosi neurologica è variabile ma nell'80% dei casi è favorevole. Incidenza: 7 bambini milione/anno. Clinica: cefalea improvvisa, convulsioni, coma, alterazioni oculari i più frequenti. I fattori di rischio, in accordo con la triade di Virchow: trombofilia congenita o acquisita, danno endoteliale (es: flogosi, infezioni) e stasi del flusso sanguigno (es: policitemia). Diagnosi: anamnesi, esame obiettivo, Rm cerebrale, in alternativa eseguire la TC encefalo, se queste negative può essere utile un'angio…

Correlazione tra danno cerebrale e quadri istopatologici placentari

2009

La Paralisi Cerebrale Infantile (PCI) è una delle più comuni infermità dell'infanzia. Le cause responsabili del danno encefalico sono molteplici e vengono classicamente suddivise in prenatali, perinatali e postnatali. Nel presente lavoro è stata condotta un'analisi delle alterazioni istopatologiche a carico della placenta e degli altri annessi fetali, al fine di valutare possibili correlazioni tra le alterazioni macro e microscopiche a livello placentare e l'outmcome neurologico neonatale.

Immediate effects of the respiratory stimulation on ventilation parameters in ischemic stroke survivors: A randomized interventional study (CONSORT).

2019

Background: Post-stroke brain damage, which affects the central control of respiration, leads to various respiratory disorders. They can be caused by the weakening of the respiratory muscles and chest movements, which can indirectly contribute to an impairment of the ventilation function. The aim of the study is an objective assessment of the effect of a single-session intervention of respiratory stimulation through Proprioceptive Neuromuscular Facilitation (PNF) on chosen respiratory parameters and the following comparison of these changes with a group in which positioning was used (intra- and intergroup comparison). Methods: This was a randomized interventional study evaluating the respir…

Global Impact of the COVID-19 Pandemic on Cerebral Venous Thrombosis and Mortality

2022

[Background and Purpose] Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year.

Update on mechanism and therapeutic implications of spinal cord stimulation and cerebral hemodynamics: A narrative review

2017

Spinal cord stimulation (SCS) is well known for its early role in the management of chronic pain, mainly failed back surgery syndrome (FBSS), spasticity, and bowel and bladder dysfunction. In more recent years, SCS has been proposed for patients suffering from refractory angina or peripheral vasculopathies in order to gain symptom relief, thus indicating some hemodynamic effect on the peripheral circulation. Taking into account this scientific observation, since the late1980s, researchers have started to investigate the potential effect of SCS on cerebral blood flow (CBF) regulation and its possible application in certain pathological settings dealing with vascular pattern dysfunction, such…

Use of middle cerebral velocity and blood pressure for the analysis of cerebral autoregulation at various frequencies: The coherence index

1998

A common component in many protocols for the evaluation of cerebral autoregulation is the comparison of transcranial Doppler ultrasound (TCD) velocities with blood pressure recordings, in which correlations between these two signals correspond to impaired autoregulation. With long data sets and complicated paradigms, however, visual inspection alone cannot adequately distinguish random coincidence from consistent correlation in a statistically valid fashion. We suggest and illustrate the use of the coherence index for this purpose. To illustrate this technique, long-term recordings of TCD velocity and blood pressure were obtained from 6 normal subjects and using 23 data segments from 8 pati…

ERYTHROPOIETIN FOR THE TREATMENT OF SUBARACHNOID HEMORRAGE: A FEASIBLE INGREDIENT FOR A SUCCESS MEDICAL RECIPE

2015

Subarachnoid hemorrhage (SAH) following aneurysm bleeding accounts for 6% to 8% of all cerebrovascular accidents. Although an aneurysm can be effectively managed by surgery or endovascular therapy, delayed cerebral ischemia is diagnosed in a high percentage of patients resulting in significant morbidity and mortality. Cerebral vasospasm occurs in more than half of all patients after aneurysm rupture and is recognized as the leading cause of delayed cerebral ischemia after SAH. Hemodynamic strategies and endovascular procedures may be considered for the treatment of cerebral vasospasm. In recent years, the mechanisms contributing to the development of vasospasm, abnormal reactivity of cerebr…
