Resumen
La inmunoglobulina G materna (IgG) que cruza la placenta puede dañar a los recién nacidos. La terapia intravenosa de inmunoglobulina (Ig) ayuda a tratar estas afecciones al interferir con la IgG materna, pero requiere más capacitación del proveedor.
Área de la Ciencia:
- Inmunología Inmunología.
- Perinatología Perinatología.
- Neonatología Neonatología.
Sus antecedentes:
- La inmunidad materna se adapta durante el embarazo, pero los anticuerpos IgG maternos pueden cruzar la placenta.
- Los anticuerpos IgG maternos preexistentes pueden causar enfermedades fetales y neonatales.
- Estas condiciones incluyen la enfermedad hemolítica del recién nacido y la trombocitopenia no inmune neonatal.
Objetivo del estudio:
- Revisar la terapia intravenosa de inmunoglobulina (Ig) para las afecciones fetales y neonatales.
- Para discutir la formulación, los mecanismos, las indicaciones y la administración de la terapia de Ig.
- Para resaltar la necesidad de una formación integral para los proveedores.
Principales métodos:
- Revisión de la literatura sobre la terapia con Ig en medicina fetal y neonatal.
- Análisis de la transferencia de IgG a través de la placenta.
- Examen del papel de la terapia de Ig en trastornos alojimunes neonatales específicos.
Principales resultados:
- La IgG materna plantea riesgos para los fetos y los recién nacidos.
- La terapia intravenosa de Ig es un tratamiento establecido para estas afecciones.
- La terapia de Ig funciona interfiriendo con las interacciones nocivas de IgG maternales.
Conclusiones:
- La Ig intravenosa es crucial para el manejo de los trastornos no inmunes neonatales.
- Comprender los matices de la terapia de Ig es vital para los proveedores fetales y neonatales.
- La educación adicional sobre la terapia de Ig es esencial para una atención óptima del paciente.

01:15Development of the Sexual Organs in the Embryo and Fetus
3.9K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

4.4K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

27.7K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
Exposure therapy is a cornerstone of behavioral treatment for anxiety disorders. It involves systematic exposure to feared stimuli, either in real...

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.
