A retrospective review of the Department of Histopathology files at the Adelaide Children's Hospital was conducted to examine all cases where sudden death (defined as death occurring within 24 h of sudden collapse and unconsciousness in a previously apparently well child) was attributable to hemorrhage from an occult central nervous system lesion. Ten cases were found with significant hemorrhage and associated cerebral edema. The diagnoses were cerebral arteriovenous malformation (1), probable cerebellar vascular malformation (4), berry aneurysm of middle cerebral artery (1), cerebellar medulloblastoma (1), optic chiasm astrocytoma (1), pineal gland teratoma (1), and fourth ventricle ependymoma (1). These cases demonstrate the wide range and variable location of intracranial lesions capable of causing sudden death in children. Careful examination of the brain in all cases of sudden pediatric death is essential so that intracranial lesions causing unexpected death will be adequately characterized.

Background: The safety data of lecanemab in the post-marketing period has yet to be fully investigated in the current literature. We aimed to identify and characterise the safety profile of lecanemab in the post-marketing period.
Methods: We searched and reviewed the reports submitted to the FDA's Adverse Event Reporting System (FAERS).

Status epilepticus is linked to cognitive decline due to damage to the hippocampus, a key structure involved in cognition. The hippocampus's high vulnerability to epilepsy-related damage is the main reason for this impairment. Convulsive seizures, such as those observed in status epilepticus, can cause various hippocampal pathologies, including inflammation, abnormal neurogenesis, and neuronal death.

Cell cycle checkpoints are the regulatory mechanisms that secure the strict order of cellular events for cell division that ensure genome integrity. It has been proposed that mitosis initiation depends on the completion of DNA replication, which must be tightly controlled to guarantee genome duplication. Contrary to these conventional hypotheses, we showed here that cells were able to enter mitosis without completion of DNA replication.

Sudden unexpected death in epilepsy (SUDEP) is a devastating complication of epilepsy with possible sex-specific risk factors, although the exact relationship between sex and SUDEP remains unclear. To investigate this, we studied Kcna1 knockout (Kcna1) mice, which lack voltage-gated Kv1.1 channel subunits and are widely used as a SUDEP model that mirrors key features in humans.

Background: This study aimed to gather information about parental practices, knowledge, and attitudes regarding infant sleep habits and environments, among families who practice non-recommended sleep practices.
Methods: We conducted one-on-one phone interviews with parents who had practiced non-recommended sleep methods with their infant and had or had not experienced an undesirable sleep event such as a fall. Interviews were recorded and coded with MAXQDA software.
