AI Article Synopsis
- Isolated bilateral absence of the inferior rectus muscle is a rare condition that leads to eye movement issues and distinctive head positioning from a young age.
- A 45-year-old woman showed symptoms like bilateral ptosis and limited eye movement but maintained a normal head posture.
- After surgery that repositioned the horizontal rectus muscles, her symptoms visibly improved.
Article Abstract
Isolated bilateral absence of the inferior rectus muscle is a rare congenital anomaly. The usual presentation of this disorder involves apparent ocular deviations and abnormal head posture from an early age. A 45-year-old woman presented with a bilateral ptosis and lower scleral show. She had a limitation of infraduction in both eyes but was orthophoric in the primary position and had a normal head posture. Ocular motility testing and imaging confirmed a diagnosis of bilateral absence of the inferior rectus muscle; the ptosis was assumed to be a pseudoptosis. The inferior half of the horizontal rectus muscles was transposed inferiorly in both eyes. Postoperatively there was marked improvement of the bilateral ptosis and lower scleral show.

Background: Chronic kidney disease (CKD) is a leading cause of death in the United States, and renal fibrosis represents a pathologic hallmark of CKD. Extracellular cold-inducible RNA-binding protein (eCIRP) is a stress response protein involved in acute inflammation, tissue injury and regulated cell death. However, the role of eCIRP in chronic inflammation and tissue injury has not been elucidated.

Department of Clinical Neurophysiology, Federal University of São Paulo, São Paulo, SP, Brazil.
Purpose: Electrical stimulation of trigeminal nerve branches elicits early and late reflex responses in the cervical muscles, known as the trigeminocervical reflex (TCR). This study aimed to evaluate the neurophysiological aspects, stimulation patterns, and topographic distribution of short-latency TCR components in humans in the absence of voluntary muscle activation.
Methods: This prospective observational study included 30 participants.

Article Synopsis
- Traumatic brain injury (TBI) is a leading cause of death, complicating the development of effective therapies due to the unique nature of each injury.
- Clinical questions regarding the benefits of measuring intracranial pressure, cerebral perfusion pressure, and surgical interventions remain largely unanswered.
- This study focused on acute subdural hematoma in a porcine model to better understand secondary brain injury and the effects of different injury patterns on outcomes, highlighting the need for comprehensive models to improve TBI treatment translation.
