Human neuropathological and animal model evidence supporting a role for Fas-mediated apoptosis and inflammation in cervical spondylotic myelopathy. The most skilled stonemasons cannot construct a cathedral without an ample supply of fine granite blocks. Likewise, the human brain cannot be built properly if stocks of neuroglial progenitors (the building blocks of the brain) are depleted by injury during the critical period of progenitor cell proliferation and migration, as occurs in germinal matrix haemorrhage in prematurity. The article by Prof. Marc Del Bigio (2011), representing the analysis of a career-spanning autopsy cohort of preterm infants with and without germinal matrix haemorrhage, he addresses a persistent clinical concern facing paediatric specialists caring for survivors of prematurity: what are the consequences of germinal matrix haemorrhage on normal brain development at the micro-anatomic level, and do they explain observed neurodevelopmental and neuroimaging outcome data? As a serious complication of prematurity, germinal matrix haemorrhage and its frequent accompaniment, intraventricular haemorrhage , have been recognized in the medical literature …

Cell proliferation in human ganglionic eminence and suppression after prematurity-associated haemorrhage.
In premature infants, germinal matrix haemorrhage in the brain is a common occurrence. However, cell proliferation and fate determination in the normal human germinal matrix is poorly understood. Human ganglionic eminence samples were collected prospectively from autopsies of premature and term infants with no evidence of pathological process (n=78; dying at post-menstrual age 14-88 weeks). The...

متن کاملEarly and late complications of germinal matrix-intraventricular haemorrhage in the preterm infant: what is new?
Germinal matrix-intraventricular haemorrhage (GMH-IVH) remains a serious problem in the very and extremely preterm infant. This article reviews current methods of diagnosis, treatment and neurodevelopmental outcome in preterm infants with low-grade and severe GMH-IVH. We conclude that there is still no consensus on timing of intervention and treatment of infants with GMH-IVH, whether or not com...

متن کاملLow cerebral blood flow is a risk factor for severe intraventricular haemorrhage.
AIMS To investigate the relation between cerebral blood flow on the first day of postnatal life and the severity of any subsequent germinal matrix haemorrhage-intraventricular haemorrhage (GMH-IVH). METHODS Cerebral blood flow was measured in 24 babies during the first 24 hours of life using near infrared spectroscopy. Repeated cerebral ultrasound examination was performed to define the maxim...
