Takotsubo syndrome (TS) is an acute heart disease that mimics the typical features of acute coronary syndrome (ACS). TS is generally reported after subarachnoid hemorrhage (SAH) due to a ruptured aneurysm, and has an incidence rate of 0.8 (17%). Here, we report a rare case of TS with unruptured intracranial aneurism. A 54‐year‐old woman had a histo...

Background Subarachnoid hemorrhage (SAH) prognosis remains poor. Vasospasm mechanism might be associated with inflammation. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been studied as inflammation markers and prognostic predictors. Objective We aimed to investigate NLR and PLR in admission as predictors of angio...

Background: Glioblastoma is the most common type of malignant glioma and is one of the most frequent primary tumors during adult life. The platelet-lymphocyte ratio (PLR) has been studied as an inflammatory marker associated with the prognosis of glioblastoma in previous studies. Considering the morbidity associated with this condition, it is impo...

Introduction: Following the advent of artificial intelligence (AI), a number of medical machine learning models have emerged. Since timing for adequate medical care is fundamental, this article seeks to confront data and point out which of the machine learning models – Logistic Regression (LR) or Support Vector Machine (SVM) – for brain injury is m...

Fibrolipomatous hamartoma is a rare benign tumor‐like condition that affects most commonly the median nerve. The diagnosis is usually confirmed through its typical appearance on magnetic resonance imaging (MRI) without the need for a nerve biopsy. There are divergent views regarding treatment of this entity, but open carpal tunnel release for nerve...

A 3‐year‐old male patient was brought to the Emergency Department with a traumatic blunt lesion in the liver. Due to hemodynamic instability and a severe lesion of a grade IV liver injury shown on the CT, the chosen conduct was to perform a hepatorrhaphy with oxidized cellulose. Surgical treatment of liver trauma consists of bleeding control. There...

Background Shoulder abduction is crucial for daily activities, and its restoration is one of the surgical priorities. We evaluated the predictive factors of shoulder abduction functional outcome after spinal accessory nerve (SAN) to suprascapular nerve (SSN) transfer, with special emphasis on the effect of time from injury to the surgery, in the tr...

Primary cardiac tumors are very rare, accounting for 0,001 – 0,03% in autopsy series, cardiac myxoma (CM) account for approximately 50% of them. Association between CM and cerebral aneurism is well documented in this condition but the occurrence of cerebral aneurism after resection of CM is very rare there is only 40 reports in medical literature....

Ruptured intracranial aneurysms, as the leading cause of spontaneous subarachnoid hemorrhage (aSAH), represents an emergency with high morbi-mortality. The comprehension of the underlying pathology that involves inflammatory and immune responses, through the neutrophil-to-lymphocyte ratio (NLR), could help to predict complications such as delayed c...

Introduction:Peripheralfacial paralysis is one of the most commonand aggressive nerve injuries. Currently, there are several classic sur-gical techniques and variants for reversing this condition of paralysis.Methods:A systematic review of the current literature was con-ducted using the PRISMA guidelines for scientific articles publishedin PubMed a...

BACKGROUND: Though anatomy of the brachial plexus is well known, its fascicular anatomy is still a challenge. In case of the musculocutaneous nerve (MCN), the position of the motor branches at its terminations is well known; however, their position in the lateral cord has been rarely investigated. OBJECTIVE: To describe the position of motor branch...

Objective To evaluate publication trends in non-obstetric brachial plexus injury research. Methods In September 2020, we searched Scopus for articles on non-obstretric brachial plexus injury.

Gliomas are the main type of intra-axial primary brain tumors. We performed a systematic review of studies on the neutrophil-to-lymphocyte ratio (NLR) and its role in the prognosis of patients with gliomas. An English-language literature-based search, using the PubMed and Biblioteca Virtual em Saúde databases, was conducted for papers published unt...

Purpose: in literature the expression 'professional vocation' is used to describe a specific area of science (craft, occupation, profession) that the person is easier to perform and can be identified by psychological tests, the authors evaluated the correlation between having or not vocation for medical school and academic success.

Objectives Several factors are commonly associated with the occurrence of post-operative infection after craniotomy. However, the risk factors associated with tumor surgery have been less intensively investigated. The aim of the present study was to analyze the risk factors for infection and categorize patients according to risk rate. Methods In t...

Introduction: Chronic subdural haematoma (CSDH) is one of the most common neurosurgical pathologies. The recurrence of chronic subdural haematomas is an important concern, considering that elderly patients are the most affected and reoperations in these patients may represent a risk of neurological and clinical complications. In accordance with th...

Background Acute flaccid myelitis (AFM) syndrome consists of loss of lower motor neurons following a viral infection, with preserved sensory function. It usually affects the upper limbs asymmetrically, with proximal more than distal muscle involvement.Methods Five cases were surgically treated with nerve transfers: spinal accessory to suprascapular...
