The valleculae can collect saliva to prevent initiation of the swallowing reflex. The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis.
One of the most common locations for a foreign body is the alimentary tract. It is possible for foreign bodies to enter the tract either from the mouth, [1] or from the rectum. [2] The objects most commonly swallowed by children are coins. [3] Meat impaction, resulting in esophageal food bolus obstruction is more common in adults. [4]
Micrograph showing a Mallory body with the characteristic twisted-rope appearance (centre of image - within a ballooning hepatocyte). H&E stain. In histopathology, a Mallory body, Mallory–Denk body (MDB), or Mallory's hyaline is an inclusion found in the cytoplasm of liver cells. [1] Mallory bodies are damaged intermediate filaments within ...
Increased respiratory rate may be the only sign of foreign body aspiration in a child who cannot verbalize or report if they have swallowed a foreign body. [6] If the foreign body does not cause a large degree of obstruction, patients may present with chronic cough, asymmetrical breath sounds on exam, or recurrent pneumonia of a specific lung ...
The bodies are prevented from decaying by means of plastination, a rubberization process patented in the 1970s by anatomist Gunther von Hagens.The essence of the process is the replacement of water and fatty material in the cells of the body first by acetone and then by plastics, such as silicone rubber, polyester or epoxy resin.
An esophageal food bolus obstruction is a medical emergency caused by the obstruction of the esophagus by an ingested foreign body.. It is usually associated with diseases that may narrow the lumen of the esophagus, such as eosinophilic esophagitis, Schatzki rings, peptic strictures, webs, or cancers of the esophagus; rarely it can be seen in disorders of the movement of the esophagus, such as ...
Medical plastics include a wide range of products from bags to pharmaceutical containers that leach and expose patients and healthcare workers to MNPs. [73] Further research is needed to assess toxicology and medical significance of MNPs from medical plastics. Microplastics per square meter in the EU sewage sludge (2015–2019) [74]
Plastination is a technique or process used in anatomy to preserve bodies or body parts, first developed by Gunther von Hagens in 1977. [1] The water and fat are replaced by certain plastics , yielding specimens that can be touched, do not smell or decay , and even retain most properties of the original sample.
