Abstract

Cysticercosis is a tissue infection caused by larvae of the cestode Taenia solium. Neurocysticercosis is a central nervous system form of this infection. Taenia solium invades tissues in a form of a cyst with a thin, semitransparent wall. It can reach 1-2 cm in diameter in muscles and brain tissue and up to 3-6 cm in brain chambers. Pigs are the most common intermediate hosts. The infection occurs when the parasite eggs or proglottids are ingested. It is most common in regions where human feces is used as a fertilizer, or regions with poor sanitary conditions. The man is infected with contaminated food or water, or by autoinoculation. The Taenia solium eggs are hatched in the duodenum. Embryos invade the intestinal mucosa, and reach various parts of the body, disseminated by the blood circulatory system. The most common localizations of cysticerci are skeleton, muscles and brain. While alive, these cysts produce a minimal reaction in hosts. Inflammation occurs when they die, often a few years after infection. While presence of adult worms of Taenia solium in the gastrointestinal tract causes unspecific symptoms, clinical features of neurocysticercosis depend on the number, size and localization of cysts, as well as on the degre...Continue Reading

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia is a congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the right ventricle wall and loss of myocardial cells. Primary injuries usually are at the free wall of the right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
