Resumen
Ojo seco en Sjögren
Área de la Ciencia:
- Oftalmología e Inmunología
Sus antecedentes:
- Tradicionalmente, la disfunción de la glándula lagrimal era el foco principal para el ojo seco en la enfermedad de Sjögren (SjD).
- La evidencia emergente implica la disfunción de la glándula meibomiana (MGD) como un factor significativo en el ojo seco relacionado con la SjD.
Objetivo del estudio:
- Examinar el papel de la MGD en el ojo seco relacionado con la enfermedad de Sjögren.
- Explorar los mecanismos potenciales y las estrategias actuales de gestión de la MGD en la SjD.
Principales métodos:
- Revisión de la evidencia reciente sobre la estructura y la función de la glándula de Meibomio en pacientes con SjD.
- Análisis de los vínculos fisiopatológicos propuestos entre MGD y SjD.
- Evaluación de los enfoques terapéuticos existentes para la MGD asociada a la SjD.
Principales resultados:
- Los pacientes con SjD presentan daño severo de la glándula meibomiana, reducción de la capa lipídica lagrimal y aumento de la evaporación de las lágrimas.
- Estos factores contribuyen al ojo seco evaporativo, desafiando el modelo de deficiencia acuosa.
- La inflamación, la deficiencia de andrógenos y los factores neurológicos son posibles contribuyentes de la vía MGD-SjD.
Conclusiones:
- La disfunción de la glándula de Meibomian es un contribuyente clave al ojo seco en la enfermedad de Sjögren.
- Los tratamientos actuales pueden ser subóptimos debido al enfoque limitado en la MGD relacionada con la SjD.
- La investigación adicional sobre las terapias dirigidas de MGD para SjD es crucial para mejorar los resultados de los pacientes.

Accessory Structures of the Skin: Sebaceous Glands
2.3K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Myasthenia Gravis: Overview and Treatment
1.9K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Salivary Glands and Saliva
953
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

Disorders of the Skeletal Muscle
1.1K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Myasthenia Gravis: Diagnostic Tests
1.3K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Exocrine Glands: Methods of Secretion
4.7K
Exocrine glands are those that release their secretions through ducts. Based on their mode of secretion, they can be classified into merocrine, apocrine, and holocrine.
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
