Nasal Septal Abscesses: A Systematic Review.

Background: Nasal septal abscesses (NSA) necessitate prompt recognition and management to prevent morbidity and long-term sequelae. To date, no comprehensive review of NSA alone has been conducted.

Objective: To conduct a systematic review of the presentation and management of NSA and determine patients at risk of sequelae.

How Reliable Is the Posterior Belly of the Digastric Muscle in Preventing Carotid Injury During Neck Dissection?

The posterior belly of the digastric muscle, referred to as the "resident's friend," serves as a valuable anatomical landmark because identification of its location during head and neck surgery helps to secure vital structures. A 53-year-old female was referred for an oral cavity mass with a biopsy confirmed squamous cell cancer. A physical exam revealed a 4 cm long and 2 cm wide right ulcerated oral tongue mass.

Limbic system synaptic dysfunctions associated with prion disease onset.

Misfolding of normal prion protein (PrP) to pathological isoforms (prions) causes prion diseases (PrDs) with clinical manifestations including cognitive decline and mood-related behavioral changes. Cognition and mood are linked to the neurophysiology of the limbic system. Little is known about how the disease affects the synaptic activity in brain parts associated with this system.

Natural history of dolichoectatic vertebrobasilar aneurysms: a multinational study.

Objective: Dolichoectatic vertebrobasilar aneurysms (DVBAs) are expansions of arterial tissue leading to aneurysmal formations without an obvious neck. Their natural history is poorly understood; usually patients are admitted with thromboembolic complications and/or neurological symptoms from the mass effect. There have not been international collective data, and correct timing for highly risky treatments has been under discussion.
