Summary
Severe, multilayered retinal hemorrhages (RHs) with retinoschisis in infants are highly specific indicators of abusive head trauma, distinguishing it from other causes.
Area of Science:
- Ophthalmology
- Pediatrics
- Forensic Medicine
Background:
- Abusive head trauma (AHT) is a significant cause of infant morbidity and mortality.
- Retinal hemorrhages (RHs) are common findings in children with AHT.
Purpose of the Study:
- To review the evaluation of children with RHs.
- To differentiate RHs caused by AHT from other etiologies.
- To discuss the pathophysiology and distinguishing features of AHT-related RHs.
Main Methods:
- Review of existing literature on retinal hemorrhages in children.
- Focus on differential diagnosis and distinguishing features of AHT-related RHs.
- Discussion of ophthalmologic consultation indications and examination timing.
Main Results:
- Non-AHT causes of RHs typically present nonspecific patterns.
- Severe, multilayered RHs extending to the retinal periphery, especially with retinoschisis, are specific to AHT.
- Retinoschisis is rarely associated with accidental trauma, and such events are usually well-documented.
Conclusions:
- Ophthalmologic findings, particularly severe peripheral RHs with retinoschisis, are critical in diagnosing AHT.
- Distinguishing AHT-related RHs from other causes is crucial for appropriate child protection.
- Understanding the significance of specific RH patterns aids in timely diagnosis and intervention.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
1.3K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

01:19Muscles that Move the Head
6.0K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

01:26Arteries of the Head and Neck
3.3K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:19Veins of Head and Neck
5.6K
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...

01:13Induced Pluripotent Stem Cells
28.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

01:24Vision
60.1K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
