Background:
In December 2019, in Wuhan, a new virus emerged, causing severe acute respiratory syndrome (SARS) secondary to infection by a type of coronavirus, causing coronavirus disease (COVID-19). The pandemic caused by the new coronavirus has had implications in the central nervous system. COVID-19 is known to be characterized by coagulation activation and endothelial dysfunction, causing ischemic and hemorrhagic vascular syndromes.
Case Description:
A 27-year-old male patient case with progressive decrease in visual acuity, associated with respiratory symptoms and intense headache. Multilobar infiltrate with a reticulonodular pattern is evident on chest CT scan. Brain CT scan with pituitary macroadenoma apoplexy was shown. SARS-Cov2 was confirmed, and respiratory support initiated. However, the patient died shortly afterward, secondary to pulmonary complications.
Conclusion:
The angiotensin-converting enzyme (ACE) II receptor is expressed in circumventricular organs and in cerebrovascular endothelial cells, which play a role in vascular autoregulation and cerebral blood flow. For this reason, is rational the hypothesize that brain ACE II could be involved in COVID-19 infection. Underlying mechanisms require further elucidation in the future.
Background:
Traumatic spinal cord injury (TSCI) is a devastating problem typically associated with multi-organ disorders. Studies regarding TSCI and their attendant comorbidities are scarce from developing countries.
Methods:
The electronic files of 147 patients with TSCI (2017–2018) were reviewed; 78% of patients were males averaging 38 years of age. The following variables associated with the TSCI included age, sex, etiology of trauma, vertebral level, fracture classification, Frankel grade, treatment, complications, and mortality.
Results:
Of interest, most cases involved thoracic injuries with attendant chest trauma resulting from falls from substantial heights.
Conclusion:
In Mexico, the majority of TSCI occur in young males (average age 38) who have sustained falls from significant heights resulting in thoracic fractures with a high frequency of chest injuries. By providing such information for developing countries, we may develop future strategies to TSCI in vulnerable populations.
The aim of this study was to evaluate the efficiency of brain abscess drainage by neuronavigation, with a case report and review of the literature. Clinical case: A 45-year-old male with headache, fever, and abdominal pain, presented liver and brain abscesses. The operation was performed by draining the liver abscesses through endoscopy, and brain abscesses by neuronavigation, using a single burr hole and a puncture-aspiration technique on the first attempt, without residual abscesses and a neurological deficit. Conclusion: The drainage of brain abscesses with the described technique is high in safety, precision, and effectiveness, avoiding the performance of a wide craniotomy, with less aggression to healthy tissue.
El conocimiento de las contribuciones a la cirugía de columna realizadas a través del tiempo, nos proporciona el contexto del entendimiento de las técnicas quirúrgicas actuales y del éxito que ha tenido esta área con el paso de los años. En este trabajo el autor realizó una búsquea de los hitos históricos que marcaron el rumbo de la cirugía de columna, lo cual representó un arduo trabajo por grandes figuras de la medicina, partiendo desde la mitología Egipcia, pasando por el periodo Griego, Arábico y el Renacimiento, hasta la Edad Moderna y el desarrollo de la cirugía de mínima invasión.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
