Lesión axonal difusa en lesiones en la cabeza causadas por una caída
Lancet (London, England)
|December 22, 1984
Resumen
Las caídas desde alturas significativas están fuertemente relacionadas con la lesión axonal difusa (DAI) en lesiones fatales en la cabeza. Las caídas simples, no desde una distancia considerable, no suelen causar DAI.
Área de la Ciencia:
- Neuropatología y Neuropatología.
- Medicina para traumas Medicina para traumas
- Ciencias Forenses Ciencias Forenses.
Sus antecedentes:
- La lesión axonal difusa (DAI) es una consecuencia común de un traumatismo craneal severo.
- Comprender los mecanismos y las causas de la DAI es crucial para la prevención y el tratamiento de las lesiones.
Objetivo del estudio:
- Investigar la asociación entre las caídas y la lesión axonal difusa (DAI) en las lesiones en la cabeza no fatales por misiles.
- Para determinar si la altura de caída influye en la aparición de DAI.
Principales métodos:
- Análisis retrospectivo de los hallazgos de la necropsia en 635 pacientes con lesiones en la cabeza no fatales por misiles.
- Categoría de las lesiones en la cabeza basadas en el mecanismo de caída (caída simple vs. caída desde una altura considerable).
Principales resultados:
- La lesión axonal difusa (DAI) se identificó en 82 casos (13% de la muestra total).
- De los 13 casos con DAI atribuidos a caídas, todos los involucrados caen desde una altura considerable.
- Se encontró una asociación estadísticamente significativa entre DAI y caídas desde una altura considerable.
- No se observó DAI en los casos resultantes de caídas simples (caídas que no exceden la altura de la persona).
Conclusiones:
- Las caídas desde una altura considerable son una causa significativa de lesión axonal difusa (DAI) en el trauma craneal fatal.
- Es poco probable que las caídas simples resulten en una lesión axonal difusa (DAI).
- Los hallazgos destacan la importancia de la altura de caída como un factor crítico en la causalidad de la DAI.

Flail Chest-I
Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology

Flail Chest-II
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Traumatic Brain Injury l: Introduction
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
