Ultrasound findings and prognosis of shoulder pain: a role for Doppler signal?

Purpose: To find ultrasound prognostic factors for shoulder pain. Methods: This was an observational, prospective study, comparing the evolution of ultrasound findings with clinical outcomes, in patients with shoulder pain. Data were collected in two appointments, from February 2018 to March 2021. Two-tailed non-parametric statistics were used, and p values <0.05 were considered significant. Results: A total of...

Is there progression of endolymphatic hydrops in Ménière’s disease? Longitudina...

Background: Endolymphatic hydrops (EH) is universal in Ménière´s disease (MD). Given its chronic course, with variable interval before complete clinical picture is installed, it seems relevant to understand the progression of vestibular EH and hemato-perilymphatic barrier disruption in patients with MD and monosymptomatic presentations. Methods: 239 consecutive patients were referred to us with suspected hydrop...

POST-DISSECTION THORACO-ABDOMINAL ANEURYSMS: RESULTS OF OPEN AND ENDOVASCULAR R...

Introduction/Objectives: Repair of post-dissection thoraco-abdominal aortic aneurysms (PD-TAAA) is a complex challenge. Choosing the correct approach to manage these aneurysms is not straightforward as both open and endovascular strategies are valid. Our aim was to analyze and compare the results of PD-TAAA treated by endovascular or open surgery. Methods: A seven-year (January-2013 and May-2020) single-center ...

Long-term Neuropsychiatric and Neuropsychological Sequelae of Endovascularly Tr...

Introduction: There is limited evidence regarding long-term outcomes of aneurysmal subarachnoid hemorrhage survivors. Most follow-up programs are relatively short and focused on physical functions. Endovascular aneurysmal embolization enables recovery of normal vascular architecture. However, there is growing evidence that neuropsychological and behavior sequelae can significantly impact the lives of these pati...

Neuromelanin magnetic resonance imaging of the Substantia Nigra in LRRK2-relate...

Neuromelanin magnetic resonance imaging of the substantia nigra in LRRK2-relate...

Specific T-weighted MRI sequences are able to detect SN neuromelanin (NM) signal changes and accurately discriminate Parkinson’s disease (PD) patients from controls. The study of NM-MRI in PD patients carrying a LRRK2 gene mutation (LRRK2-PD) could contribute to further uncover LRRK2-associated phenotype. Albeit considered to largely overlap idiopathic PD (iPD), differences have been described. Furthermore, the...

Substantia nigra neuromelanin-MR imaging differentiates essential tremor from P...

Background: Essential tremor (ET) is a very common movement disorder that has no diagnostic markers. Differentiation with Parkinson's disease (PD) can be clinically challenging in some cases, with a high rate of misdiagnosis. Magnetic resonance imaging (MRI) studies have been able to identify neuromelanin changes in the substantia nigra (SN) of PD patients, but they have thus far not been investigated in ET. In...

Quantitative analysis versus visual assessment of Neuromelanin MR Imaging for t...

Background: Specific MR sequences have been able to identify the loss of neuromelanin in the substantia nigra (SN) of early stage Parkinson's disease (PD) patients. Since this technique may have a significant impact in clinical patient management, easy and widely available imaging analysis is needed for routine use. Objective: In this study we compared a quantitative analysis with a visual assessment of SN neur...

Um Caso Grave de Doença de Rendu-Osler-Weber

Os autores apresentam um caso de Doença de Rendu-Osler-Weber com evolução particularmente grave, numa adolescente de 16 anos.Trata-se de uma doente do sexo feminino, em que foi detectada acidentalmente, aos três anos de idade, hepatomegália. Os estudos subsequentesmostraram fibrose hepática e, posteriormente, fístulas artériovenosas cerebrais e fístulas artériovenosas pulmonares com insuficiência respiratóriaim...
