Four cases of serious congenital cytomegalovirus (CMV) infections are described in this report. All cases were diagnosed postnatally using cerebrospinal fluid (3/4) or blood PCR (1/4) and histochemical study of the placenta (4/4). All infants were born prematurely. Maternal factors identified as significant were younger age at pregnancy and those from low-income social strata. The major clinical findings among patients with congenital CMV infection were hydrocephalus and persistent thrombocytopenia. The children's clinical condition did not improve over the course of the disease, leading to complications associated with extreme prematurity. Two of the children died, one of whom had severe brain malformations and showed neurological compromise at follow-up, seizures, motor impairment, and severe cognitive delay. It is essential to perform antenatal screening for possible CMV infection among pregnant women, even in countries with high population seropositivity, such as Mexico, to establish prenatal interventions to reduce the risk of fetal damage.

Background: Individuals with Down syndrome (DS) have an increased genetic risk of developing Alzheimer's disease (AD), with most adults developing AD neuropathology in their 40s. Despite having a low frequency of systemic vascular risk factors such as hypertension and atherosclerosis, adults with DS display cerebrovascular pathology, including microbleeds, microinfarcts, and cerebral amyloid angiopathy. This suggests that blood-brain barrier (BBB) integrity may be compromised allowing the extravasation of blood proteins in the brain parenchyma.

Background: It is well established that genetic factors are implicated in the development of Alzheimer's disease (AD), but there is growing interest in how environmental factors like infection contribute to its progression. Recent evidence suggests that greater exposure to infections across the lifespan can potentiate the rate and severity of cognitive decline. In addition to contributing to mechanisms underlying the aggregation of Aβ fragments and phosphorylation of tau proteins, the infectious etiology of dementia may be caused by infectious agents triggering neuroinflammatory pathways and degradation of the blood-brain barrier (BBB).

Psychiatric disorders, including anxiety and depression, are highly comorbid in people with epilepsy. However, the mechanisms mediating the shared pathophysiology are currently unknown. There is considerable evidence implicating the basolateral amygdala (BLA) in the network communication of anxiety and fear, a process demonstrated to involve parvalbumin-positive (PV) interneurons.

Wolcott-Rallison Syndrome is an extremely rare syndrome characterized by infantile non-autoimmune diabetes, extensive skeletal dysplasia, and multi-organ failure requiring transplant. Prognosis is very poor, and as such, surgical intervention for symptomatic cervical spine compromise in pediatric patients has not been widely reported in part due to their high fragility. We report a complex case of Wolcott-Rallison Syndrome that presented with cervical myelopathy due to cervicomedullary compression and the exceptional surgical considerations required for successful intervention.

Here we presented the initial experience of clipping aneurysms using fully endoscopic techniques and aimed to evaluate the safety and feasibility of fully endoscopic techniques for aneurysms. This was a retrospective single-center study in which patients were scheduled to undergo aneurysm clipping using fully endoscopic techniques. We collected patients' records, radiological neuroimaging, aneurysm-related variables and surgical procedures in detail, as well as postoperative outcomes.
