Cervicomedullary primitive neuroectodermal tumor of the spine: Case report.

Background: Intramedullary primitive neuroectodermal tumors (PNETs) are tumors found rarely in the cervical region, with only five such cases described in the literature. The available literature contains only one report regarding cervicomedullary junction PNET.

Case Description: The authors present a case report of a 45-year-old male patient who had undergone urgent hospitalization owing to progressive tetraparesis and subtle impairment of respiratory function.

Microcephaly caused by congenital Zika virus infection and viral detection in maternal urine during pregnancy.

Currently Latin America is undergoing a major epidemic of Zika virus, which is transmitted by Aedes mosquitoes. Concern for Zika virus infection has been increasing as it is suspected of causing brain defects in newborns such as microcephaly and, more recently, potential neurological and autoimmune complications including Guillian-Barré syndrome and acute disseminated encephalomyelitis. We describe a case of virus infection in a 25-year-old woman during the first trimester of her pregnancy, confirmed by laboratory tests only for the detection of viral particles in maternal urine, with imaging studies demonstrating the progression of cranial and encephalic changes in the fetus and later in the newborn, such as head circumference reduction, cerebral calcifications and ventriculomegaly.

Late evaluation of the relationship between morphological and functional renal changes and hypertension after non-operative treatment of high-grade renal injuries.

Objective: To evaluate the anatomical and functional renal alterations and the association with post-traumatic arterial hypertension.

Methods: The studied population included patients who sustained high grades renal injury (grades III to V) successfully non-operative management after staging by computed tomography over a 16-year period. Beyond the review of medical records, these patients were invited to the following protocol: clinical and laboratory evaluation, abdominal computed tomography, magnetic resonance angiography, DMSA renal scintigraphy, and ambulatory blood pressure monitoring.
