Parasitic Diseases List

Body lice lay eggs on clothing, feed on human blood, and can transmit disease to humans. People without housing and living in crowded conditions have a higher risk of body lice than others. Lice are parasitic insects, meaning they need a host to survive. Three types of lice feed on humans: head lice, pubic lice, and body lice. All species of lice are different, but they die without access to human blood. The effects of lice on humans often involve severe itching and scratching that can lead to skin infections. Lice eventually die without feeding on humans, and treatment involves removing them. This article explains the causes, symptoms, and treatment of body lice. Body lice live on human clothing. They measure about 2.3 to 3.6 millimeters (mm) and are flat and white or gray in appearance. Despite their name, they live on clothing and move onto the body only to feed. For this reason, some people refer to them as clothes lice. These lice can transmit diseases, including: relapsing fever...

1 Introduction T. gondii has the ability to infect any nucleated cell of any warm-blooded animal or bird, including those of humans, giving it possibly the widest host range of any parasite (Tenter et al., 2000). T. gondii , being acquired orally and not requiring a vector, is not geographically limited and is estimated to have infected approximately one-third of the global human population (Montoya and Liesenfeld, 2004; Hill et al., 2005). It can remain latent in the majority of its hosts, but can be deadly in immunocompromised people, and create severe adverse impacts on the unborn if acquired during pregnancy. Acute toxoplasmosis can result in severe cerebral outcomes including retinochoroiditis, encephalitis, hydrocephalus, convulsions and intracerebral calcification (Hill et al., 2005). In most immunocompetent humans, however, toxoplasmosis does not need treatment and protective immunity is naturally acquired. However, treatment is vital for toxoplasmos...

May 15, 2024 Von Willebrand disease (VWD) occurs with equal frequency among men and women, affecting up to 1% of the general population. Women are more likely to experience symptoms of VWD because of the increased bleeding it causes during their menstrual periods, during pregnancy, and after childbirth. Prevalence Von Willebrand disease (VWD) occurs with equal frequency among men and women, affecting up to 1% of the general population. 12 However, women are more ...

Von Willebrand disease (VWD) is the most common inherited bleeding disorder. The condition gets its name after Erik von Willebrand—a doctor who identified the disease in the 1920s. Your blood contains many proteins that help it clot properly and prevent excess blood loss. One of these proteins is called the "von Willebrand factor." This protein helps bind and clump with blood platelets, which are cell fragments in the blood that also help with clotting. When von Willebrand factor is present in your blood at low levels or if it's not working properly, you can experience heavy and frequent bleeding, like nosebleeds or abnormal menstrual bleeding. However, there are effective treatments available to manage the condition—and people who receive treatment can have healthy and active lives. There are four types of VWD and knowing what type you have is important. That's because each type has its own prognosis (outlook) and treatment plan. The types of VW...

Introduction Acquired von Willebrand syndrome (AVWS) is a rare hemorrhagic disease, similar to hereditary von Willebrand disease (VWD) in laboratory tests and clinical manifestations. AVWS primarily occurs in adults without a personal or family history of bleeding diathesis, characterized by mucocutaneous or gastrointestinal bleeding. Laboratory tests reveal prolonged bleeding time and low levels of plasma factor VIII (FVIII) and von Willebrand factor (VWF) measurements (1). Unlike VWD, AVWS is almost associated with an underlying disease. According to a survey of AVWS by the International Society of Thrombosis and Hemostasis (ISTH) in 2000, among the 186 cases, the associated diseases were lymphatic hyperplasia (48%), myeloproliferative diseases (15%), tumors (5%), immunology (2%), cardiovascular (21%) and other diseases (9%) related (2). Systemic lupus erythematosus (SLE) is a rare cause of AVWS. Herein, we report a case of AVWS as onset clinical presentation of SLE manifested as e...
