Resumen
Las toxinas de los mariscos que causan el envenenamiento de los peces globo, la ciguatera y el envenenamiento paralítico de los mariscos bloquean los canales de sodio nervioso. Se propone que estas condiciones, clínicamente indistinguibles, se denominen parálisis pelágica.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Toxicología Toxicología.
- Biología Marina Biología Marina.
Sus antecedentes:
- La intoxicación por peces globo, la ciguatera y la intoxicación por mariscos paralíticos son enfermedades distintas transmitidas por los mariscos.
- Estas condiciones comparten un mecanismo de acción común que involucra canales de sodio controlados por voltaje.
Objetivo del estudio:
- Proponer un término unificador para los síndromes de envenenamiento por mariscos clínicamente indistinguibles.
- Para resaltar el mecanismo neurotóxico compartido de estos envenenamientos.
Principales métodos:
- Observación clínica y comparación de los síntomas en diferentes intoxicaciones por mariscos.
- Revisión de los datos toxicológicos y neurológicos existentes sobre las toxinas marinas.
Principales resultados:
- El envenenamiento por peces globo, la ciguatera y el envenenamiento paralítico por mariscos muestran presentaciones clínicas superpuestas.
- Las tres condiciones son el resultado de toxinas que bloquean los canales de sodio en los nervios.
- Se propone una nueva entidad clínica, la "parálisis pelágica", para abarcar estos síndromes.
Conclusiones:
- La parálisis pelágica es un concepto unificador para envenenamientos específicos de mariscos con neurotoxicidad compartida.
- La variabilidad de la presentación clínica se atribuye a las diferencias en la concentración de toxinas dentro de los mariscos consumidos.
- Esta clasificación ayuda a comprender y potencialmente diagnosticar estos síndromes neurológicos.

Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Botulism
Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
