Flaccid paralysis is a neurological condition characterized by weakness or paralysis and reduced muscle tone without other obvious cause (e.g., trauma). This abnormal condition may be caused by disease or by trauma affecting the nerves associated with the involved muscles. For example, if the somatic nerves to a skeletal muscle are severed, then the muscle will exhibit flaccid paralysis. When muscles enter this state, they become limp and cannot contract. This condition can become fatal if it affects the respiratory muscles, posing the threat of suffocation. It also occurs in spinal shock stage in complete transection of spinal cord occurred in injuries like gunshots injuries. Causes
Polio and other viruses
The term acute flaccid paralysis (AFP) is often used to describe an instance with a sudden onset, as might be found with polio.AFP is the most common sign of acute polio, and used for surveillance during polio outbreaks. AFP is also associated with a number of other pathogenic agents including enteroviruses other than polio, echoviruses, West Nile virus, and adenoviruses, among others. Botulism
The Clostridium botulinum bacteria are the cause of botulism. Vegetative cells of C. botulinum may be ingested. Introduction of the bacteria may also occur via endospores in a wound. When the bacteria are in vivo, they induce flaccid paralysis. This happens because C. botulinum produces a toxin that blocks the release of acetylcholine. Botulism toxin blocks the exocytosis of presynaptic vesicles containing acetylcholine (ACh). When this occurs, the muscles are unable to contract.
Aluminosis (also known as aluminium lung) is a restrictive lung disease caused by exposure to aluminum-bearing dust. Aluminosis is a form of pneumoconiosis that can lead to pulmonary fibrosis. First cases of lung damage from aluminium exposure were reported in 1930s in Germany. It can be detected by using high-resolution computed tomography. Findings may vary, showing nodular or slightly irregular opacities that may merge into more prominent forms, most frequently in the upper lung fields, sometimes in the lower lung fields, and less frequently a diffuse micro nodular pattern. In severe cases, pulmonary fibrosis with honeycombing was described.Workers exposed to aluminium dust are often involved in industries such as explosives manufacturing (where aluminium powder is involved), aluminium welding (and grinding), and bauxite smelting.
