Resumen
Los cambios en la inervación del esfínter uretral externo son comunes en los recién nacidos con mielodisplasia, que a menudo ocurren dentro del primer año. El monitoreo continuo es crucial debido a la naturaleza dinámica de esta condición.
Área de la Ciencia:
- Neurología Pediátrica.
- Urología Urología Urología.
- Biología del desarrollo Biología del desarrollo.
Sus antecedentes:
- La mielodisplasia es una afección congénita que afecta el desarrollo neuronal.
- La función neurológica y urodinámica puede cambiar con el tiempo en los niños afectados.
Objetivo del estudio:
- Para evaluar cambios en la inervación del esfínter uretral externo en recién nacidos con mielodisplasia.
- Para identificar los factores de riesgo y el momento de estos cambios.
- Para evaluar el impacto de las intervenciones neuroquirúrgicas.
Principales métodos:
- Evaluaciones secuenciales roentgenográficas, neurológicas y urodinámicas.
- Seguimiento longitudinal de 79 recién nacidos con mielodisplasia durante 1,5 a 6 años.
Principales resultados:
- El 37% de los bebés mostró cambios en la inervación del esfínter dentro de los primeros tres años, predominantemente en el primer año (89,6%).
- El 19% experimentó un deterioro neurourológico, mientras que el 18% mejoró.
- Los segundos procedimientos neuroquirúrgicos dieron resultados mixtos: mejora en 4, estabilización en 2 y deterioro en 1 bebé.
Conclusiones:
- Los cambios en la inervación del esfínter uretral externo son un proceso dinámico en la mielodisplasia.
- La vigilancia neurológica y urológica temprana y continua es esencial para el manejo de estos niños.

01:15Differentiation of Common Myeloid Progenitor Cells
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
01:22Bone Marrow Sampling and Transplants
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...

01:24Cellular Adaptation IV: Dysplasia and Metaplasia
DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
