Delivering acute stroke care in a middle-income country. The Mexican model: "ResISSSTE Cerebro".

Introduction: Founded in 2019, the "ResISSSTE Cerebro" program is the first and only stroke network within the Mexican public health system. One advanced stroke center (ASC) and seven essential stroke centers (ESC) provide acute stroke (AS) care through a modified hub-and-spoke model. This study describes the workflow, metrics, and outcomes in AS obtained during the program's third year of operation.

Matrix metalloproteinase-2 and matrix metalloproteinase-9 serum levels in patients with vertebrobasilar dolichoectasia with and without stroke: case-control study.

Purpose: To describe the differences in the serum levels of MMP-2 and MMP-9 of patients with vertebrobasilar dolichoectasia (VBD) with and without acute stroke.

Methods: Case-control study. From an outpatient clinic, we recruited 14 controls and 19 patients with VBD.

Multilevel percutaneous vertebroplasty with the Spine Jack® system in a patient with Cushing disease.

Background: Percutaneous vertebroplasty (PV) is a minimally invasive procedure that requires the injection of cement into a fractured vertebral body. Spine Jack® is a vertebroplasty system with an intracorporal implant designed to restore the height of the vertebral body in osteoporotic vertebral fractures. There are no reported cases of PV with Spine Jack® system as treatment for multilevel compression fractures in patients with vertebral osteoporosis due to Cushing disease.

Clinical presentation and magnetic resonance findings in sellar tuberculomas.

Background and Importance. Sellar tuberculomas are extremely rare lesions with nonspecific clinical manifestations. The tuberculous infection of the pituitary gland and sellar region is characterized by the presence of an acute or chronic inflammatory reaction and may occur in the absence of systemic tuberculosis.

Endovascular treatment: balloon angioplasty versus nimodipine intra-arterial for medically refractory cerebral vasospasm following aneurysmal subarachnoid hemorrhage.

Cerebral vasospasm (CV) accounts significant morbimortality after aneurysmal subarachnoid hemorrhage. The objective of this study was to compare the clinical outcome of patients with CV treated by 2 endovascular procedures: intra-arterial nimodipine angioplasty (IANA) and balloon angioplasty (BA). Between 2008 and June 2011, we performed 22 IANA and 8 BA in 30 patients.

Asymptomatic carotid rete mirabile and contralateral carotid agenesis: a case report.

Carotid rete mirabile (CRM) is a physiological network between the external carotid artery (ECA) and internal carotid artery (ICA) in lower mammals. It is a transdural arterial network centered at the parasellar area, in anatomical localization of intracavernous or petrous segment of ICA, associated with hypoplasia or absence of the cervical or petrous segment of ICA. It clinically presents as hemorrhagic or ischemic cerebrovascular disorder.

Sinus pericranii: case report.

Sinus pericranii (SP) is an abnormal communication between the intracranial and extracranial venous drainage pathways. Treatment of this condition has mainly been recommended for aesthetic reasons and prevention of hemorrhage. The authors report a conservative treatment for the potentially lethal complications.

A modified protocol using half-dose gadolinium in dynamic 3-Tesla magnetic resonance imaging for detection of ACTH-secreting pituitary tumors.

Unlabelled: ACTH-secreting tumors represent 10% of functioning pituitary adenomas, and most of them are microadenomas. It is generally accepted that only half of these tumors are correctly identified with current magnetic resonance imaging (MRI) techniques. The objective of the paper is to report a method for detecting suspected ACTH-secreting pituitary tumors undetectable by conventional dynamic MRI using dynamic 3-Tesla MRI (3T MRI) and half-dose gadopentetate dimeglumine (0.
