Opsoclonus-myoclonus-ataxia syndrome associated with central nervous system HIV-1 escape phenomenon.

Introduction: Opsoclonus-myoclonus-ataxia (OMA) syndrome is a rare neurological disorder characterized by involuntary conjugate saccadic eye movements, myoclonus, and ataxia. Few reports exist on patients with HIV and OMA.

Case Report: A 41-year-old man diagnosed with HIV-1 infection in 1997 coursed with multiple anti-retroviral schemes as a consequence of poor adherence.

Identification of risk factors for central nervous system metastasis in patients with breast cancer with neurologic symptoms.

Background: The current study was performed to identify factors that are present at the time of breast cancer (BC) diagnosis that are associated with a higher rate of central nervous system metastasis (CNSm).

Methods: The authors analyzed a database of patients with a confirmed diagnosis of BC who were referred for a neuro-oncology consultation at the National Cancer Institute in Mexico City, Mexico, from June 2009 to June 2017. Information was collected prospectively and included demographic, pathologic, and clinical data at the time of diagnosis of BC.

Vertigo in patients with cancer: Red flag symptoms.

Introduction: Vertigo is a common condition occurring in the general population and is usually self-limited. Reports studying vertigo in patients with brain metastasis (BM), are scarce. Therefore, the aim of this study was to analyze if the presence of vertigo in cancer patients is associated with the presence of BM.

Association of neurologic manifestations and CEA levels with the diagnosis of brain metastases in lung cancer patients.

Purpose: Lung cancer (LC) is the most common source of brain metastases (BM). Because of the difficulty in predicting LC patients who will develop BM, we aimed to identify the clinical and serologic markers that could predict the presence of BM in LC patients.

Methods: We analyzed a cohort of LC patients sent for neurooncological consultation for any neurologic symptom at a cancer center from June 2013 to July 2017.

Clinical presentation, risk factors and outcome of central nervous system metastasis vs stroke in cancer patients.

Background And Purpose: Cancer and stroke are the second and third causes of death worldwide; brain metastases (BM) occur in one third of patients with cancer, any neurologic deficit in these population always prompts the clinician to discard metastases for their presence carries a bad outcome. Both might share clinical presentation and differences in their outcome are not entirely known. The aim was to compare risk factors, clinical presentation, and outcome of cancer patients with BM vs stroke.
