Cerebral larva migrans in a raccoon (Procyon lotor). (1/39)
During 1997, gross and histopathologic examinations were performed on an adult female raccoon (Procyon lotor) that was live-trapped in Corvallis, Oregon. Multifocal eosinophilic granulomas indicative of neural and visceral larva migrans were observed. However, within these granulomas, the presence of parasitic larva was seen only in the cerebrum. Morphologic characteristics indicated that the nematode was an ascarid larva. However, it was smaller than the larva of Baylisascaris sp. This appears to be the first documented case of cerebral larva migrans in a raccoon. (+info)Radiologic-pathologic findings in raccoon roundworm (Baylisascaris procyonis) encephalitis. (2/39)
A 13-month-old boy developed eosinophilic meningoencephalitis, retinitis, and a protracted encephalopathy with severe residual deficits. The initial MR examination revealed diffuse periventricular white matter disease, and follow-up images showed atrophy. Brain biopsy, serology, and epidemiologic studies lead to the diagnosis of Baylisascaris procyonis infection, a parasitic disease contracted through exposure to soil contaminated by the eggs of a common raccoon intestinal roundworm. The pathologic, epidemiologic, and imaging features of this disease are herein reviewed. (+info)Highlights of human toxocariasis. (3/39)
Human toxocariasis is a helminthozoonosis due to the migration of Toxocara species larvae through human organism. Humans become infected by ingesting either embryonated eggs from soil (geophagia, pica), dirty hands or raw vegetables, or larvae from undercooked giblets. The diagnosis relies upon sensitive immunological methods (ELISA or western-blot) which use Toxocara excretory-secretory antigens. Seroprevalence is high in developed countries, especially in rural areas, and also in some tropical islands. The clinical spectrum of the disease comprises four syndromes, namely visceral larva migrans, ocular larva migrans, and the more recently recognized "common" (in adults) and "covert" (in children) pictures. Therapy of ocular toxocariasis is primarily based upon corticosteroids use, when visceral larva migrans and few cases of common or covert toxocariasis can be treated by anthelmintics whose the most efficient appeared to be diethylcarbamazine. When diagnosed, all of these syndromes require thorough prevention of recontamination (especially by deworming pets) and sanitary education. (+info)Visceral larva migrans due to Ascaris suum which presented with eosinophilic pneumonia and multiple intra-hepatic lesions with severe eosinophil infiltration--outbreak in a Japanese area other than Kyushu. (4/39)
A 32-year-old man presented with the chief complaint of severe cough. Examination of peripheral blood showed a marked increase in eosinophils. Chest CT demonstrated multiple ground glass opacities in both lungs. Bronchoalveolar lavage showed abundant eosinophils. Abdominal CT demonstrated multiple low attenuation areas in the liver. Liver biopsy with ultrasonography revealed severe eosinophil infiltrations around the portal veins. Serologically, a multi-dot enzyme linked immunosorbent assay (DOT-ELISA) and ELISA inhibition test using microtiter plates were positive for Ascaris suum. Thus, visceral larva migrans due to Ascaris suum was diagnosed. Outbreaks of this disease in Japan have previously been confined to the Kyushu area. The present case which occurred outside that area, illustrates the importance of constant attention to the epidemiology of this disease. (+info)Chronic eosinophilic pneumonia due to visceral larva migrans. (5/39)
A 38-year-old woman presented with worsening cough, blood eosinophilia, and pulmonary infiltrates. Bronchoalveolar lavage showed 96.4% eosinophils. The diagnosis of visceral larva migrans (VLM) was made based on the positive results in enzyme-linked immunosorbent assay for Toxocara canis together with clinical symptoms and laboratory data. Pulmonary infiltrates due to VLM generally manifest as a transient form of Loffler's syndrome or simple eosinophilic pneumonia mainly in children. Here we report an adult case of VLM, with pulmonary infiltrates pathologically proven to be eosinophilic pneumonia, which persisted for 7 weeks before anthelmintic treatment with albendazole and manifested as chronic eosinophilic pneumonia. (+info)Myocarditis associated with visceral larva migrans due to Toxocara canis. (6/39)
A 26-year-old man who was diagnosed with myocarditis presented eosinophilia after having eaten raw meat several times before the admission. Since the antibody titer against Toxocara canis was high, we diagnosed that he had visceral larva migrans due to Toxocara canis associated with myocarditis and eosinophilia. He was then treated with oral albendazole and prednisolone for 4 weeks and eosinophil count and hepatic enzymes were normalized along with the decrease in the antibody titer. We consider that his myocarditis was probably caused by direct larval migration and/ or by hypersensitivity reaction, for which combined therapy with albendazole and prednisolone was effective. (+info)A seroepidemiological survey for toxocariasis in apparently healthy residents in Gangwon-do, Korea. (7/39)
We investigated the sero-prevalence of toxocariasis among healthy Korean adults in 1999. A total of 314 sera from normal inhabitants in Whachon-gun, Gangwondo, Korea was examined for specific antibody levels against excretory-secretory products of second stage larvae of Toxocara (TES). The presence of cross-reactions with other helminthiases such as cysticercosis, paragonimiasis, sparganosis or clonorchiasis was also checked by specific IgG ELISA. Sera showing positive reaction against TES were also tested by IgG immunoblot and by IgE ELISA. Out of 314 subjects, 16 was found to be positive by TES IgG ELISA and immunoblot, among whom 12 were also positive by TES IgE ELISA. Among the 16 seropositive samples, two sera showed positive reaction against Paragonimus and sparganum antigen, respectively. These results inferred that cross-reactions were negligible between toxocariasis and other helminthiases. Toxocariasis seroprevalence among Korean rural adults was detected to be approximately 5%. (+info)Roundworm granuloma of the anterior abdominal wall. (8/39)
A case of migration of a gravid female roundworm into the peritoneal cavity is reported. The presenting feature, a lump in the anterior abdominal wall, has not previously been documented. Fertilized ova of the worm were found in miliary peritoneal granulomata, and showed development up to the eight-cell stage. (+info)Larva migrans is a parasitic infection caused by the larval stage of certain nematode (roundworm) species. The term "larva migrans" is used to describe two distinct clinical syndromes: cutaneous larva migrans and visceral larva migrans.
1. Cutaneous Larva Migrans (CLM): Also known as creeping eruption, it is caused by the hookworm species that typically infect dogs and cats (Ancylostoma braziliense, Ancylostoma caninum). The larvae penetrate human skin, usually through bare feet in contact with contaminated soil or sand, and cause an intensely pruritic (itchy) serpiginous (snake-like) track as they migrate under the skin.
2. Visceral Larva Migrans (VLM): It is caused by the migration of larvae from certain roundworm species, such as Toxocara spp., which primarily infect canids (dogs and related animals). Humans become accidental hosts when they ingest embryonated eggs present in contaminated soil, water, or undercooked meat. The larvae then migrate through various organs, causing inflammation and damage to tissues. VLM often affects the liver, lungs, eyes, and less commonly the central nervous system. Symptoms can vary widely depending on the organs involved but may include fever, cough, abdominal pain, and eye inflammation.
It is important to note that these infections are not transmitted from person-to-person. Preventive measures include wearing shoes in areas with contaminated soil, washing hands thoroughly after contact with soil or pets, cooking meat properly, and avoiding the ingestion of dirt or sand by young children.
Visceral Larva Migrans is a parasitic infection caused by the migration of the larval stage of certain nematode roundworms, such as Toxocara spp. (most commonly Toxocara canis or Toxocara cati), through the tissues of the host. The larvae are ingested, usually through the consumption of contaminated soil, water, or undercooked meat, and then penetrate the intestinal wall, entering the bloodstream and migrating to various organs, including the liver, lungs, central nervous system, and eyes. This condition is more commonly seen in children due to their higher likelihood of engaging in pica (the consumption of soil or other non-food items) and having close contact with pets that may carry these parasites. Symptoms can vary widely depending on the organs involved but often include fever, coughing, wheezing, abdominal pain, and skin rashes. In severe cases, it can lead to potentially life-threatening complications such as blindness or neurological damage. Diagnosis typically involves a combination of clinical presentation, imaging studies, and laboratory tests, such as serology or stool examination for parasite eggs. Treatment usually consists of anthelmintic medications to eliminate the parasites and supportive care to manage symptoms.
Ascaridoidea is a superfamily of parasitic nematode roundworms that includes several medically important genera such as Ascaris, Toxocara, and Baylisascaris. These worms have a complex life cycle involving intermediate hosts like insects or mammals, and definitive hosts such as humans or other animals.
In humans, the most common species of Ascaridoidea are Ascaris lumbricoides (also known as "human roundworm") and Toxocara canis (dog roundworm) or Toxocara cati (cat roundworm). Infection with these parasites typically occurs through ingestion of contaminated food, water, or soil.
Ascaris lumbricoides infection, known as ascariasis, can cause symptoms such as abdominal pain, nausea, vomiting, and diarrhea. Severe infections may lead to intestinal obstruction, malnutrition, or impaired growth in children.
Toxocara infection, also called toxocariasis, can result in visceral larva migrans (VLM) or ocular larva migrans (OLM), depending on the organs affected. VLM may cause fever, cough, wheezing, and hepatomegaly, while OLM can lead to vision loss or eye inflammation.
Preventive measures include proper hygiene practices, such as handwashing, cooking food thoroughly, and avoiding contact with contaminated soil or feces. In some cases, medication may be necessary to treat these infections.
Erythema chronicum migrans (ECM) is a type of skin rash that is commonly associated with early Lyme disease. It is usually the first sign of infection after a tick bite and is caused by the bacterium Borrelia burgdorferi. The rash typically appears within 3-30 days after the tick bite and starts as a red, flat or slightly raised spot at the site of the bite. Over several days or weeks, the redness expands, forming a circular or oval-shaped rash that can be up to 12 inches in diameter. The center of the rash may clear, giving it a "bull's-eye" appearance.
ECM is usually accompanied by symptoms such as fatigue, fever, headache, and muscle and joint pain. It is important to note that not all people with Lyme disease will develop ECM, and its absence does not necessarily mean that the person does not have Lyme disease. If you suspect that you may have been bitten by a tick and are experiencing symptoms of Lyme disease, it is important to seek medical attention promptly.
"Toxocara canis" is a species of roundworm that primarily infects canids, such as dogs and foxes. The adult worms live in the intestines of the host animal, where they lay eggs that are passed in the feces. These eggs can then mature and become infective to other animals, including humans, if they ingest them.
In humans, infection with "Toxocara canis" can cause a range of symptoms known as toxocariasis, which can include fever, coughing, wheezing, rash, and abdominal pain. In severe cases, the larvae of the worm can migrate to various organs in the body, including the eyes, leading to potentially serious complications.
Preventive measures for "Toxocara canis" infection include good hygiene practices, such as washing hands after handling pets or coming into contact with soil that may contain infected feces, and regular deworming of pets.
Ascaridida infections are caused by roundworms belonging to the order Ascaridida, which includes several species that can infect humans and animals. The most common species that infects humans is Ascaris lumbricoides, also known as the human roundworm. Other species that can cause infection in humans include Toxocara spp., Baylisascaris procyonis, and Ascaris suum (the pig roundworm).
Infection with these parasites typically occurs through ingestion of contaminated food or water containing eggs or larvae. The larvae hatch in the small intestine and then migrate through the body to various organs, including the liver, lungs, and eyes, where they can cause damage. After several weeks, the larvae return to the small intestine, where they mature into adult worms and begin producing eggs.
Symptoms of ascariasis (infection with Ascaris lumbricoides) can vary depending on the severity of the infection and the location of the worms in the body. Mild infections may cause no symptoms or only mild gastrointestinal symptoms such as abdominal pain, nausea, and diarrhea. More severe infections can lead to intestinal obstruction, malnutrition, and other complications.
Infection with Toxocara spp. can cause a condition called visceral larva migrans, which is characterized by fever, cough, rash, and liver enlargement. Ocular larva migrans can occur when the larvae migrate to the eye, causing inflammation and potentially leading to vision loss.
Baylisascaris procyonis infection can cause a similar condition called neural larva migrans, which can lead to neurological symptoms such as seizures, muscle weakness, and paralysis.
Prevention of Ascaridida infections involves practicing good hygiene, including washing hands thoroughly with soap and water after using the toilet or handling soil or contaminated objects. Proper cooking and cleaning of food can also help prevent infection. In areas where ascariasis is common, treatment of human waste and improvement of sanitation infrastructure can help reduce transmission.
Toxocara is a type of parasitic roundworm that belongs to the genus Toxocara. The two most common species that infect humans are Toxocara canis and Toxocara cati, which are primarily found in dogs and cats, respectively.
Humans can become infected with Toxocara through accidental ingestion of contaminated soil or sand that contains the eggs of the parasite. This can occur when people come into contact with infected animal feces and then touch their mouths without properly washing their hands. Children are particularly at risk of infection due to their frequent hand-to-mouth behaviors and tendency to play in environments where the eggs may be present.
In humans, Toxocara infection can cause a range of symptoms known as toxocariasis. The most common form is visceral larva migrans (VLM), which occurs when the parasite's larvae migrate through various organs in the body, causing inflammation and damage. Symptoms of VLM may include fever, fatigue, coughing, wheezing, abdominal pain, and liver enlargement.
Another form of toxocariasis is ocular larva migrans (OLM), which occurs when the parasite's larvae migrate to the eye, causing inflammation and potentially leading to vision loss. Symptoms of OLM may include eye pain, redness, blurred vision, and light sensitivity.
Preventive measures for Toxocara infection include washing hands thoroughly after handling animals or coming into contact with soil, covering sandboxes when not in use, and cooking meat thoroughly before eating. Treatment for toxocariasis typically involves anti-parasitic medications such as albendazole or mebendazole, which can help kill the parasite's larvae and reduce symptoms.
I'm sorry for any confusion, but "raccoons" are not a medical term. They are a species of nocturnal mammals native to North America, known for their distinctive black facial mask and ringed tails. If you have any questions about animals or a medical condition, feel free to ask!
Albendazole is an antiparasitic medication used to treat a variety of parasitic infections, including neurocysticercosis (a tapeworm infection that affects the brain), hydatid disease (a parasitic infection that can affect various organs), and other types of worm infestations such as pinworm, roundworm, hookworm, and whipworm infections.
Albendazole works by inhibiting the polymerization of beta-tubulin, a protein found in the microtubules of parasitic cells, which disrupts the parasite's ability to maintain its shape and move. This leads to the death of the parasite and elimination of the infection.
Albendazole is available in oral form and is typically taken two to three times a day with meals for several days or weeks, depending on the type and severity of the infection being treated. Common side effects of albendazole include nausea, vomiting, diarrhea, abdominal pain, and headache. Rare but serious side effects may include liver damage, bone marrow suppression, and neurological problems.
It is important to note that albendazole should only be used under the supervision of a healthcare provider, as it can have serious side effects and interactions with other medications. Additionally, it is not effective against all types of parasitic infections, so proper diagnosis is essential before starting treatment.
Toxocariasis is a parasitic infection caused by the roundworms Toxocara canis or Toxocara cati, which are found in the intestines of dogs and cats, respectively. Humans become infected through the accidental ingestion of infective eggs from contaminated soil, water, or food. The larvae hatch in the small intestine and migrate to various tissues, including the liver, lungs, eyes, and central nervous system, where they can cause inflammation and damage.
The severity of the infection depends on the number of larvae that have infected the body and the organs involved. Most infections are asymptomatic or mild, causing symptoms such as fever, cough, rash, or abdominal discomfort. However, in severe cases, toxocariasis can lead to serious complications, including blindness (ocular larva migrans) or neurological damage (visceral larva migrans).
Preventive measures include good hygiene practices, such as washing hands after handling soil or pets, and avoiding contact with dog or cat feces. Regular deworming of pets can also help reduce the risk of transmission.
Ancylostoma is a genus of parasitic roundworms that are commonly known as hookworms. These intestinal parasites infect humans and other animals through contact with contaminated soil, often via the skin or mouth. Two species of Ancylostoma that commonly infect humans are Ancylostoma duodenale and Ancylostoma ceylanicum.
Ancylostoma duodenale is found primarily in tropical and subtropical regions, including parts of the Mediterranean, Africa, Asia, and southern Europe. It can cause a disease called ancylostomiasis or hookworm infection, which can lead to symptoms such as abdominal pain, diarrhea, anemia, and impaired growth in children.
Ancylostoma ceylanicum is found mainly in Southeast Asia, southern China, and some parts of Australia. It can also cause ancylostomiasis, with symptoms similar to those caused by Ancylostoma duodenale. However, Ancylostoma ceylanicum infections are often less severe than those caused by Ancylostoma duodenale.
Preventive measures for hookworm infection include wearing shoes in areas where the soil may be contaminated with feces, washing hands thoroughly after using the toilet or handling soil, and avoiding ingestion of contaminated soil or water. Treatment for hookworm infection typically involves administration of anthelmintic drugs to eliminate the parasites from the body.
Anthelmintics are a type of medication used to treat infections caused by parasitic worms, also known as helminths. These medications work by either stunting the growth of the worms, paralyzing them, or killing them outright, allowing the body to expel the worms through normal bodily functions. Anthelmintics are commonly used to treat infections caused by roundworms, tapeworms, flukeworms, and hookworms. Examples of anthelmintic drugs include albendazole, mebendazole, praziquantel, and ivermectin.
Benign migratory glossitis, also known as geographic tongue, is a medical condition characterized by the presence of denuded, irregularly shaped smooth patches on the dorsum of the tongue. These patches are usually red and often have a white or yellow border. The condition is called "benign migratory" because it is not harmful or cancerous, and the lesions can change in size, shape, and location over time.
The exact cause of benign migratory glossitis is unknown, but it has been associated with several factors such as stress, nutritional deficiencies (particularly vitamin B deficiency), allergies, and family history. The condition can be asymptomatic or may cause symptoms such as burning sensation, pain, or altered taste.
Treatment of benign migratory glossitis is usually not necessary unless the patient experiences discomfort or other symptoms. In such cases, topical anesthetics, antihistamines, or corticosteroids may be prescribed to alleviate the symptoms. However, if the underlying cause can be identified and addressed (such as nutritional deficiencies), the condition may improve on its own.
Central nervous system helminthiasis is a medical condition that refers to the invasion and infection of the central nervous system (CNS), specifically the brain and spinal cord, by parasitic worms, also known as helminths. This rare but serious condition can occur when helminth larvae or eggs accidentally migrate from their usual location in the body to the CNS through the bloodstream or cerebrospinal fluid.
The most common types of helminths that can cause CNS helminthiasis include:
1. Neurocysticercosis: This is caused by the larval stage of the tapeworm Taenia solium, which typically infects the muscles and brain. However, when the larvae invade the CNS, they can form cysts that cause inflammation, swelling, and damage to brain tissue.
2. Echinococcosis: This is caused by the larval stage of the tapeworm Echinococcus granulosus or Echinococcus multilocularis. The larvae can form hydatid cysts in various organs, including the brain, leading to neurological symptoms.
3. Gnathostomiasis: This is caused by the larval stage of the nematode Gnathostoma spinigerum or Gnathostoma hispidum. The larvae can migrate to various organs, including the CNS, causing inflammation and damage to brain tissue.
4. Angiostrongyliasis: This is caused by the nematode Angiostrongylus cantonensis, which typically infects rats but can accidentally infect humans through contaminated food or water. The larvae can migrate to the CNS and cause eosinophilic meningitis, an inflammation of the membranes surrounding the brain and spinal cord.
Symptoms of CNS helminthiasis depend on the type of parasite involved, the location and extent of the infection, and the host's immune response. They can range from mild to severe and may include headache, seizures, weakness, numbness, vision changes, confusion, and cognitive impairment. Diagnosis is usually based on clinical presentation, imaging studies, and laboratory tests, such as serology or CSF analysis. Treatment depends on the type of parasite involved and may include antiparasitic drugs, corticosteroids, and supportive care. Prevention measures include avoiding contaminated food and water, practicing good hygiene, and using insect repellents to prevent mosquito-borne infections.
I'm not aware of a specific medical definition for "ceremonial behavior." However, in general, ceremonial behaviors are actions or rituals that are performed in a formal, ritualistic manner, often as part of a cultural, religious, or social tradition. These behaviors can serve various purposes, such as marking important life events, expressing shared values and beliefs, or reinforcing social bonds.
In some cases, ceremonial behaviors may have health implications. For example, participation in cultural or religious rituals can provide a sense of community and support, which can have positive effects on mental health. Additionally, certain ceremonial practices, such as meditation or prayer, may have direct physiological effects that contribute to stress reduction and relaxation.
However, it's important to note that the term "ceremonial behavior" is not a medical diagnosis or clinical concept, and its meaning can vary depending on the context in which it is used.
'Ascaris suum' is a species of roundworm that primarily infects pigs, although it can also rarely infect humans. It is a type of parasitic nematode that lives in the intestines of its host and obtains nutrients from ingested food. The adult female worm can grow up to 40 cm in length and produces thousands of eggs every day. These eggs are passed in the feces of infected animals and can survive in the environment for years, making them a significant source of infection for other pigs or humans who come into contact with them.
In pigs, 'Ascaris suum' infection can cause a range of symptoms, including diarrhea, vomiting, and stunted growth. In severe cases, it can lead to intestinal blockages or pneumonia. Humans who become infected with 'Ascaris suum' typically experience milder symptoms, such as abdominal pain, coughing, and wheezing. However, in rare cases, the infection can cause more serious complications, particularly if the worms migrate to other parts of the body.
Preventing 'Ascaris suum' infection involves good hygiene practices, such as washing hands thoroughly after handling animals or coming into contact with soil that may contain infected feces. It is also important to properly cook pork before eating it and to avoid consuming raw or undercooked meat. In areas where 'Ascaris suum' is common, deworming programs for pigs can help reduce the risk of infection for both animals and humans.
Lyme disease is not a "medical definition" itself, but it is a medical condition named after the town of Lyme, Connecticut, where it was first identified in 1975. Medical definitions for this disease are provided by authoritative bodies such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). According to the CDC, Lyme disease is a "infection caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected black-legged ticks."
The WHO defines Lyme borreliosis (LB), also known as Lyme disease, as "an infectious disease caused by spirochetes of the Borrelia burgdorferi sensu lato complex. It is transmitted to humans through the bite of infected Ixodes spp. ticks."
Both definitions highlight that Lyme disease is a bacterial infection spread by tick bites, specifically from black-legged ticks (Ixodes scapularis in the United States and Ixodes pacificus on the Pacific Coast) or deer ticks (Ixodes ricinus in Europe). The primary cause of the disease is the spirochete bacterium Borrelia burgdorferi.
"Ascaridia" is a genus of parasitic roundworms that infect the gastrointestinal tract of various animals, including birds and mammals. The most common species to infect humans is Ascaris lumbricoides, also known as the "human roundworm."
Ascaridia infections can cause a range of symptoms, depending on the severity of the infestation. Mild infections may not cause any noticeable symptoms, while more severe infections can lead to abdominal pain, nausea, vomiting, diarrhea, and weight loss. In extreme cases, Ascaris worms can obstruct the intestines or migrate to other parts of the body, causing potentially life-threatening complications.
Ascaridia infections are typically transmitted through the ingestion of contaminated food or water that contains eggs shed by infected individuals. Once inside the body, the eggs hatch and release larvae that migrate to the lungs, where they mature before being coughed up and swallowed, eventually settling in the small intestine and developing into adult worms.
Preventive measures include practicing good hygiene, such as washing hands thoroughly with soap and water after using the toilet or handling soil, and cooking food thoroughly to kill any potential parasites. In areas where Ascaridia infections are common, preventive treatment with anthelmintic medications may be recommended for high-risk populations.
Parasitic skin diseases are conditions caused by parasites living on or in the skin. These parasites can be insects, mites, or fungi that feed off of the host for their own survival. They can cause a variety of symptoms including itching, rashes, blisters, and lesions on the skin. Examples of parasitic skin diseases include scabies, lice infestations, and ringworm. Treatment typically involves the use of topical or oral medications to kill the parasites and alleviate symptoms.
Acrodermatitis is a term that describes several inflammatory skin conditions characterized by redness, swelling, and blistering that typically affect the hands, feet, and face. The medical definition of acrodermatitis includes various subtypes, each with its own specific causes and symptoms. Here are some of the most common forms of acrodermatitis:
1. Acrodermatitis enteropathica: A rare inherited disorder caused by a deficiency in zinc absorption. Symptoms include redness, swelling, blistering, and crusting around the mouth, eyes, and genitals, as well as the hands and feet.
2. Acrodermatitis continua of Hallopeau: A rare chronic inflammatory skin condition that affects the fingertips and toes. Symptoms include redness, swelling, blistering, and crusting, which can lead to nail deformities and loss.
3. Gianotti-Crosti syndrome (acrodermatitis papulosa): A viral exanthem that typically affects children between 6 months and 15 years of age. Symptoms include red, raised bumps on the face, buttocks, and extremities, which can be itchy and painful.
4. Pustular acrodermatitis: A rare skin condition characterized by pustules (pus-filled bumps) that form on the palms of the hands and soles of the feet. Symptoms may also include fever, chills, and fatigue.
5. Infantile acrodermatitis: A rare inflammatory skin disorder that affects infants and young children. Symptoms include redness, swelling, and blistering around the mouth, eyes, and genitals, as well as the hands and feet.
Treatment for acrodermatitis depends on the underlying cause of the condition. In some cases, topical creams or ointments may be sufficient to manage symptoms, while in others, systemic treatments such as antibiotics or immunosuppressive drugs may be necessary.
Antibodies are proteins produced by the immune system in response to the presence of a foreign substance, known as an antigen. They are capable of recognizing and binding to specific antigens, neutralizing or marking them for destruction by other immune cells.
Helminths are parasitic worms that can infect humans and animals. They include roundworms, tapeworms, and flukes, among others. Helminth infections can cause a range of symptoms, depending on the type of worm and the location of the infection.
Antibodies to helminths are produced by the immune system in response to an infection with one of these parasitic worms. These antibodies can be detected in the blood and serve as evidence of a current or past infection. They may also play a role in protecting against future infections with the same type of worm.
There are several different classes of antibodies, including IgA, IgD, IgE, IgG, and IgM. Antibodies to helminths are typically of the IgE class, which are associated with allergic reactions and the defense against parasites. IgE antibodies can bind to mast cells and basophils, triggering the release of histamine and other inflammatory mediators that help to protect against the worm.
In addition to IgE, other classes of antibodies may also be produced in response to a helminth infection. For example, IgG antibodies may be produced later in the course of the infection and can provide long-term immunity to reinfection. IgA antibodies may also be produced and can help to prevent the attachment and entry of the worm into the body.
Overall, the production of antibodies to helminths is an important part of the immune response to these parasitic worms. However, in some cases, the presence of these antibodies may also be associated with allergic reactions or other immunological disorders.
Antinematodal agents are a type of medication used to treat infections caused by nematodes, which are also known as roundworms. These agents work by either killing the parasitic worms or preventing them from reproducing. Some examples of antinematodal agents include albendazole, ivermectin, and mebendazole. These medications are used to treat a variety of nematode infections, such as ascariasis, hookworm infection, and strongyloidiasis. It is important to note that the use of antinematodal agents should be under the guidance of a healthcare professional, as they can have side effects and may interact with other medications.
"Gnathostoma" is a genus of parasitic nematodes (roundworms) that are known to cause gnathostomiasis, a foodborne zoonotic disease. The adult worms typically infect the stomach of carnivorous animals such as cats and dogs, while the larvae can migrate through various tissues in humans and other animals, causing cutaneous and visceral lesions.
The term "Gnathostoma" itself is derived from the Greek words "gnathos" meaning jaw and "stoma" meaning mouth, which refers to the distinctive muscular mouthparts (called "hooks") that these parasites use to attach themselves to their host's tissues.
It's worth noting that there are several species of Gnathostoma that can infect humans, with Gnathostoma spinigerum being one of the most common and widely distributed species. Proper cooking and hygiene practices can help prevent gnathostomiasis infection in humans.
Ascariasis is a medical condition caused by infection with the parasitic roundworm Ascaris lumbricoides. This type of worm infection, also known as intestinal ascariasis, occurs when people ingest contaminated soil, food, or water that contains Ascaris eggs. Once inside the body, these eggs hatch into larvae, which then migrate through the tissues and eventually reach the small intestine, where they mature into adult worms.
The adult worms can grow to be several inches long and live in the small intestine, where they feed on partially digested food. Female worms can produce thousands of eggs per day, which are then passed out of the body in feces. If these eggs hatch and infect other people, the cycle of infection continues.
Symptoms of ascariasis can vary depending on the severity of the infection. Mild infections may not cause any symptoms, while more severe infections can lead to abdominal pain, nausea, vomiting, diarrhea, and weight loss. In some cases, the worms can cause intestinal blockages or migrate to other parts of the body, leading to potentially serious complications.
Treatment for ascariasis typically involves medication to kill the adult worms and prevent them from producing more eggs. Preventive measures include good hygiene practices, such as washing hands thoroughly after using the bathroom and before eating, and avoiding contact with contaminated soil or water.
Ivermectin is an anti-parasitic drug that is used to treat a variety of infections caused by parasites such as roundworms, threadworms, and lice. It works by paralyzing and killing the parasites, thereby eliminating the infection. Ivermectin is available in various forms, including tablets, creams, and solutions for topical use, as well as injections for veterinary use.
Ivermectin has been shown to be effective against a wide range of parasitic infections, including onchocerciasis (river blindness), strongyloidiasis, scabies, and lice infestations. It is also being studied as a potential treatment for other conditions, such as COVID-19, although its effectiveness for this use has not been proven.
Ivermectin is generally considered safe when used as directed, but it can cause side effects in some people, including skin rashes, nausea, and diarrhea. It should be used with caution in pregnant women and people with certain medical conditions, such as liver or kidney disease.
The Borrelia burgdorferi group, also known as the Borrelia burgdorferi sensu lato (s.l.) complex, refers to a genetically related group of spirochetal bacteria that cause Lyme disease and other related diseases worldwide. The group includes several species, with Borrelia burgdorferi sensu stricto (s.s.), B. afzelii, and B. garinii being the most common and best studied. These bacteria are transmitted to humans through the bite of infected black-legged ticks (Ixodes scapularis in the United States and Ixodes pacificus on the West Coast; Ixodes ricinus in Europe).
Lyme disease is a multisystem disorder that can affect the skin, joints, nervous system, and heart. Early symptoms typically include a characteristic expanding rash called erythema migrans, fever, fatigue, headache, and muscle and joint pain. If left untreated, the infection can spread to other parts of the body and cause more severe complications, such as arthritis, neurological problems, and carditis.
Diagnosis of Lyme disease is based on a combination of clinical symptoms, exposure history, and laboratory tests. Treatment usually involves antibiotics, such as doxycycline, amoxicillin, or ceftriaxone, and is generally most effective when initiated early in the course of the illness. Preventive measures, such as using insect repellent, checking for ticks after being outdoors, and promptly removing attached ticks, can help reduce the risk of Lyme disease and other tick-borne infections.
"Public facilities" is not a term typically used in medical definitions. However, in a broader context, public facilities generally refer to buildings, services, and infrastructure that are owned and operated by local, state, or federal government agencies for the use of the general public. These can include parks, libraries, community centers, public restrooms, transportation systems (such as buses, trains, and subways), and other similar establishments.
While not a medical definition per se, public facilities can have implications for public health and accessibility. For example, accessible public facilities are essential for individuals with disabilities to fully participate in community life. Public restrooms that are clean, well-maintained, and equipped with necessary amenities (such as grab bars and accessible sinks) can help prevent the spread of infectious diseases and ensure that all members of the community have equal access to these facilities. Similarly, public transportation systems that are safe, reliable, and accessible can improve overall community health by providing individuals with greater mobility and access to healthcare services, employment opportunities, and other essential resources.
Ancylostomatoidea is a superfamily of nematode (roundworm) parasites that includes the genera Ancylostoma and Necator, which are commonly known as hookworms. These parasites are primarily found in the small intestine of their hosts, which can include humans and other animals.
Ancylostomatoidea parasites have a complex life cycle that involves both free-living and parasitic stages. The life cycle begins when the parasite's eggs are passed in the feces of an infected host and hatch into larvae in the soil. The larvae then infect a new host by penetrating the skin, usually through contact with contaminated soil.
Once inside the host, the larvae migrate through the body to the lungs, where they mature and are coughed up and swallowed, allowing them to reach the small intestine. Here, they attach to the intestinal wall and feed on the host's blood, causing anemia and other symptoms of hookworm infection.
Hookworm infections can cause a range of symptoms, including abdominal pain, diarrhea, weight loss, and fatigue. In severe cases, they can lead to anemia, intestinal obstruction, and even death. Prevention measures include wearing shoes in areas with contaminated soil, practicing good hygiene, and treating infected individuals to prevent the spread of the parasite.
Eosinophilia is a medical condition characterized by an abnormally high concentration of eosinophils in the circulating blood. Eosinophils are a type of white blood cell that play an important role in the immune system, particularly in fighting off parasitic infections and regulating allergic reactions. However, when their numbers become excessively high, they can contribute to tissue damage and inflammation.
Eosinophilia is typically defined as a count of more than 500 eosinophils per microliter of blood. Mild eosinophilia (up to 1,500 cells/μL) may not cause any symptoms and may be discovered during routine blood tests. However, higher levels of eosinophilia can lead to various symptoms such as coughing, wheezing, skin rashes, and organ damage, depending on the underlying cause.
The causes of eosinophilia are varied and can include allergic reactions, parasitic infections, autoimmune disorders, certain medications, and some types of cancer. Accurate diagnosis and treatment of eosinophilia require identification and management of the underlying cause.
Parasitology is a branch of biology that deals with the study of parasites, their life cycles, the relationship between parasites and their hosts, the transmission of parasitic diseases, and the development of methods for their control and elimination. It involves understanding various types of parasites including protozoa, helminths, and arthropods that can infect humans, animals, and plants. Parasitologists also study the evolution, genetics, biochemistry, and ecology of parasites to develop effective strategies for their diagnosis, treatment, and prevention.
Pulmonary eosinophilia is a condition characterized by an increased number of eosinophils, a type of white blood cell, in the lungs or pulmonary tissues. Eosinophils play a role in the body's immune response to parasites and allergens, but an overabundance can contribute to inflammation and damage in the lungs.
The condition may be associated with various underlying causes, such as:
1. Asthma or allergic bronchopulmonary aspergillosis (ABPA)
2. Eosinophilic lung diseases, like eosinophilic pneumonia or idiopathic hypereosinophilic syndrome
3. Parasitic infections, such as ascariasis or strongyloidiasis
4. Drug reactions, including certain antibiotics and anti-inflammatory drugs
5. Connective tissue disorders, like rheumatoid arthritis or Churg-Strauss syndrome
6. Malignancies, such as lymphoma or leukemia
7. Other less common conditions, like tropical pulmonary eosinophilia or cryptogenic organizing pneumonia
Symptoms of pulmonary eosinophilia can vary but often include cough, shortness of breath, wheezing, and chest discomfort. Diagnosis typically involves a combination of clinical evaluation, imaging studies, and laboratory tests, such as complete blood count (CBC) with differential, bronchoalveolar lavage (BAL), or lung biopsy. Treatment depends on the underlying cause and may include corticosteroids, antibiotics, or antiparasitic medications.
'Borrelia burgdorferi' is a species of spirochete bacteria that is the primary cause of Lyme disease in humans. The bacteria are transmitted to humans through the bite of infected black-legged ticks (Ixodes scapularis in the northeastern, midwestern, and eastern parts of the United States; Ixodes pacificus on the Pacific Coast).
The bacterium was first identified and named after Willy Burgdorfer, who discovered the spirochete in the mid-1980s. The infection can lead to a variety of symptoms, including fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, the infection can spread to joints, the heart, and the nervous system, leading to more severe complications.
Antibiotic treatment is usually effective in eliminating the bacteria and resolving symptoms, especially when initiated early in the course of the disease. However, some individuals may experience persistent symptoms even after treatment, a condition known as post-treatment Lyme disease syndrome (PTLDS). The exact cause of PTLDS remains unclear, with ongoing research investigating potential factors such as residual bacterial infection, autoimmune responses, or tissue damage.
I'm sorry for any confusion, but "travel" is not a term that has a specific medical definition. In general, travel refers to the act of moving or journeying from one place to another, often over long distances. However, in a medical context, it might refer to the recommendation that individuals with certain medical conditions or those who are immunocompromised avoid traveling to areas where they may be at increased risk of exposure to infectious diseases. It's always best to check with a healthcare professional for advice related to specific medical situations and travel.
Erythema is a term used in medicine to describe redness of the skin, which occurs as a result of increased blood flow in the superficial capillaries. This redness can be caused by various factors such as inflammation, infection, trauma, or exposure to heat, cold, or ultraviolet radiation. In some cases, erythema may also be accompanied by other symptoms such as swelling, warmth, pain, or itching. It is a common finding in many medical conditions and can vary in severity from mild to severe.
Eye diseases are a range of conditions that affect the eye or visual system, causing damage to vision and, in some cases, leading to blindness. These diseases can be categorized into various types, including:
1. Refractive errors: These include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia, which affect the way light is focused on the retina and can usually be corrected with glasses or contact lenses.
2. Cataracts: A clouding of the lens inside the eye that leads to blurry vision, glare, and decreased contrast sensitivity. Cataract surgery is the most common treatment for this condition.
3. Glaucoma: A group of diseases characterized by increased pressure in the eye, leading to damage to the optic nerve and potential blindness if left untreated. Treatment includes medications, laser therapy, or surgery.
4. Age-related macular degeneration (AMD): A progressive condition that affects the central part of the retina called the macula, causing blurry vision and, in advanced stages, loss of central vision. Treatment may include anti-VEGF injections, laser therapy, or nutritional supplements.
5. Diabetic retinopathy: A complication of diabetes that affects the blood vessels in the retina, leading to bleeding, leakage, and potential blindness if left untreated. Treatment includes laser therapy, anti-VEGF injections, or surgery.
6. Retinal detachment: A separation of the retina from its underlying tissue, which can lead to vision loss if not treated promptly with surgery.
7. Amblyopia (lazy eye): A condition where one eye does not develop normal vision, often due to a misalignment or refractive error in childhood. Treatment includes correcting the underlying problem and encouraging the use of the weaker eye through patching or other methods.
8. Strabismus (crossed eyes): A misalignment of the eyes that can lead to amblyopia if not treated promptly with surgery, glasses, or other methods.
9. Corneal diseases: Conditions that affect the transparent outer layer of the eye, such as keratoconus, Fuchs' dystrophy, and infectious keratitis, which can lead to vision loss if not treated promptly.
10. Uveitis: Inflammation of the middle layer of the eye, which can cause vision loss if not treated promptly with anti-inflammatory medications or surgery.
A "Parasite Egg Count" is a laboratory measurement used to estimate the number of parasitic eggs present in a fecal sample. It is commonly used in veterinary and human medicine to diagnose and monitor parasitic infections, such as those caused by roundworms, hookworms, tapeworms, and other intestinal helminths (parasitic worms).
The most common method for measuring parasite egg counts is the McMaster technique. This involves mixing a known volume of feces with a flotation solution, which causes the eggs to float to the top of the mixture. A small sample of this mixture is then placed on a special counting chamber and examined under a microscope. The number of eggs present in the sample is then multiplied by a dilution factor to estimate the total number of eggs per gram (EPG) of feces.
Parasite egg counts can provide valuable information about the severity of an infection, as well as the effectiveness of treatment. However, it is important to note that not all parasitic infections produce visible eggs in the feces, and some parasites may only shed eggs intermittently. Therefore, a negative egg count does not always rule out the presence of a parasitic infection.
"Bites and stings" is a general term used to describe injuries resulting from the teeth or venomous secretions of animals. These can include:
1. Insect bites: The bite marks are usually small, punctate, and may be accompanied by symptoms such as redness, swelling, itching, and pain. Examples include mosquito, flea, bedbug, and tick bites.
2. Spider bites: Some spiders possess venomous fangs that can cause localized pain, redness, and swelling. In severe cases, systemic symptoms like muscle cramps, nausea, vomiting, and difficulty breathing may occur. The black widow and brown recluse spiders are notorious for their venomous bites.
3. Snake bites: Venomous snakes deliver toxic saliva through their fangs, which can lead to local tissue damage, swelling, pain, and potentially life-threatening systemic effects such as paralysis, bleeding disorders, and respiratory failure.
4. Mammal bites: Animal bites from mammals like dogs, cats, and wild animals can cause puncture wounds, lacerations, and crush injuries. They may also transmit infectious diseases, such as rabies.
5. Marine animal stings: Stings from jellyfish, sea urchins, stingrays, and other marine creatures can result in localized pain, redness, swelling, and systemic symptoms like difficulty breathing, muscle cramps, and altered heart rhythms. Some marine animals' venoms can cause severe allergic reactions or even death.
Treatment for bites and stings varies depending on the type and severity of the injury. It may include wound care, pain management, antibiotics to prevent infection, and in some cases, antivenom therapy to counteract the effects of venom. Seeking immediate medical attention is crucial in severe cases or when systemic symptoms are present.
