Isolated palsy of cranial nerve VI, also known as the abducens nerve, is a condition rarely seen in the obstetric population; however, there is a growing body of literature that suggests an association with pre-eclampsia and hypertensive disorders of pregnancy. We present the sixteenth case documenting this association involving a 30-year-old G1 admitted for induction of labor at 39 weeks gestational age (WGA) subsequently diagnosed with pre-eclampsia with severe features and, after an otherwise uncomplicated vaginal delivery, developed an isolated abducens nerve palsy. While similar cases reviewed in the current body of literature document self-resolution of the palsy, a thorough workup is warranted because of other potentially malignant causes for this presentation. Appropriate management and risk factor counseling are discussed following a review of cases.

Background: Eating disorders such as Anorexia Nervosa (AN) and Bulimia Nervosa (BN) were previously found to partly entail alterations in stress physiology including salivary cortisol (sC), and salivary alpha amylase (sAA) at rest and basal vagal tone (HF-HRV), compared to individuals without mental disorders or with mixed mental disorders (anxiety and depressive disorders), but corresponding data remain scarce and are not entirely consistent.
Method: HF-HRV, sC and sAA at rest were assessed in a female sample of 58 individuals with AN and 54 individuals with BN before and after psychotherapy and contrasted against measurements from 59 female individuals suffering from mixed disorders and 101female healthy controls.
Results: Values for sC were elevated in AN compared to all other groups, those for HF-HRV were highest in both AN and BN and lowest in mixed mental disorders and no differences were found at rest for sAA.

Vertebrobasilar dolichoectasia (VBD) is a vascular anomaly marked by abnormal elongation and dilation of the vertebral and basilar arteries. Often, VBD remains undiagnosed or is discovered incidentally during evaluations of vascular events such as ischemia, hemorrhage, hydrocephalus, or cranial nerve palsies. While most patients are managed conservatively, treatment choices are highly individualized based on clinical presentation, vessel characteristics, and risk factors.

Purpose: Neuroanatomy is a cornerstone of medical education, yet its complexity often leads to student apprehension, termed "neurophobia." This quantitative study evaluated the effectiveness of online Functional Neuroanatomy modules in enhancing second-year medical students' understanding of neuroanatomy at Weill Cornell Medicine-Qatar during the 2024-25 academic year.
Participants And Methods: Four functional neuroanatomy modules were developed: Brainstem Anatomy, Sensory Pathway, Motor Pathway, and Cranial Nerves.

Background And Purpose: To review the existing evidence on multiple timepoint assessments of optic nerve sheath diameter (ONSD) as an indicator of intraindividual variation of intracranial pressure (ICP).
Methods: A systematic search identified studies assessing intraindividual variation in ICP through multiple timepoint measurements of ONSD using ultrasonography. Meta-analysis of studies assessing intraindividual correlation coefficients between ONSD and ICP was performed using a random effects model, and we calculated the weighted correlation coefficient for the expected change in ICP associated with variations in ONSD.
