Published on: January 10, 2019
Resumen
Este estudio aclara las atrofias musculares espinales (AMS) al distinguir siete síndromes clínicos y genéticos. Los hallazgos ayudan al pronóstico y el asesoramiento genético para pacientes con AME.
Área de la Ciencia:
- Neurología Neurología.
- Genética La genética.
- La pediatría es la medicina de los niños.
Sus antecedentes:
- Las atrofias musculares espinales (AMS) exhiben una heterogeneidad clínica significativa, lo que complica el pronóstico y el asesoramiento genético.
- Las clasificaciones anteriores carecían de una correlación clínica y genética completa.
Objetivo del estudio:
- Resolver las cuestiones nosológicas en las atrofias musculares espinales (AMS) a través de un análisis clínico y genético integrado.
- Establecer un sistema de clasificación refinado para los síndromes de AME.
Principales métodos:
- Se realizaron análisis clínicos y genéticos exhaustivos en 240 casos índice de AME.
- La recopilación de datos incluyó la edad de inicio, los patrones de participación muscular, los antecedentes familiares y las pruebas genéticas.
Principales resultados:
- Se definieron siete síndromes distintos de AME basados en criterios clínicos y genéticos.
- Se identificaron trece genes mutantes diferentes como causantes.
- La AME tipo I (enfermedad de Werdnig-Hoffman) y la AME crónica infantil constituyen el 74% de todos los casos de AME.
Conclusiones:
- La clasificación propuesta discrimina los síndromes de AME utilizando la edad al inicio, la participación muscular, los antecedentes familiares y los hallazgos genéticos.
- Esta clasificación ayuda en el diagnóstico diferencial de nuevos casos de AME.
- Proporciona un marco para mejorar el pronóstico y el asesoramiento genético en las atrofias musculares espinales.

Skeletal Muscle Anatomy
Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.
Classification of Skeletal Muscle Fibers
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Classification of Connective Tissues
The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense.

Classification of Skeletal Muscle Relaxants
Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.

Fascicle Arrangement in Skeletal Muscles
Fascicles are bundles of muscle fibers in a skeletal muscle. Muscle fascicle arrangement is directly associated with the power and range of motion of various muscles. The configuration of these fascicles can vary, leading to different functional outcomes.
The four primary types of muscle based on fascicle arrangement are:

Muscles of the Vertebral Column
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
