Insights

Intracranial hypertension in syndromic craniosynostosis is multifactorial. Cognitive and behavioral issues in these patients are more likely linked to genetic factors than intracranial hypertension.

Area of Science:

  • Neuroscience
  • Genetics
  • Pediatric Surgery

Background:

  • Syndromic craniosynostosis (sCS) involves premature fusion of skull sutures, potentially leading to intracranial hypertension (ICH).
  • Understanding the mechanisms of ICH and its impact on neurodevelopmental outcomes in sCS is crucial.

Purpose of the Study:

  • To conduct a scoping review on the mechanisms of ICH in sCS.
  • To explore whether cognitive and behavioral outcomes in sCS are primarily due to genetic factors or ICH.

Main Methods:

  • A comprehensive literature search was performed across multiple databases (EMBASE, MEDLINE, Web of Science, Cochrane, Google Scholar).
  • Selected articles underwent full-text review and data extraction.
  • Analysis focused on ICH determination criteria and the Monro-Kellie doctrine components (cerebral blood volume, CSF, intracranial volume).

Main Results:

  • Ninety full-text articles were analyzed from 1893 search results.
  • Invasive intracranial pressure measurement is the gold standard for ICH diagnosis; ophthalmologic methods are the most researched noninvasive alternatives.
  • The Monro-Kellie doctrine helps explain ICH development in sCS.

Conclusions:

  • ICH in sCS arises from factors including skull growth deflection, sleep apnea, venous hypertension, and CSF flow/absorption issues.
  • Cognitive and behavioral deficits in sCS are more strongly associated with genetic origins.
  • Cortical thinning and visual impairments may result from ICH.

Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....
