Symptoma

Tissue Nematode Infection

Calabar swellings are subcutaneous edematous areas of 3-10 cm that are nonerythematous and do not pit; local pain, pruritus, and mild fever may be present. [antiinfectivedrugs.com]

A marked peripheral eosinophilia is often present. If the parasitic infection is low, eosinophilia may be the only diagnostic sign evident. Occasionally, splinter hemorrhages may be present below the nails. [clinicalgate.com]

The most common presenting feature is abdominal pain, observed in 98% of patients. Less common features include ascending cholangitis, acute pancreatitis, and, rarely, obstructive jaundice. [emedicine.medscape.com]

FIELD EVALUATION It is critical to know the nematode species present and the density of their populations to make management decisions. [ipm.ucanr.edu]

  • Localized Pain

    Calabar swellings are subcutaneous edematous areas of 3-10 cm that are nonerythematous and do not pit; local pain, pruritus, and mild fever may be present. [antiinfectivedrugs.com]

  • High Fever

    These episodes may be accompanied by high fever and resolve within 7-10 d. Epididymitis or orchitis may occur intermittently. Other patients, especially travelers, may have allergic symptoms including urticaria, rashes, and eosinophilia. [antiinfectivedrugs.com]

  • Myalgia

    Nonspecific side effects include headache, vertigo or dizziness, malaise, fever, or myalgias. Onchocerciasis should be excluded before DEC treatment. DEC is available in the United States from Lederle Laboratories (800-934-5556). [antiinfectivedrugs.com]

    She denies any myalgias, itching, or rashes. Physical and laboratory evaluations are unremarkable. Examination of her stool reveals the causative organism. [medbullets.com]

    The migration of the larvae results in an intense inflammatory response causing periorbital edema, fever, muscle pain or tenderness, headache, and myalgia. A marked peripheral eosinophilia is often present. [clinicalgate.com]

  • Pulmonary Infiltrate

    Most infections are asymptomatic, but there may be pulmonary infiltrates with eosinophilia, abdominal discomfort and—in children with heavy infections—intestinal obstruction. Infection is diagnosed by finding eggs in the faeces. [oxfordmedicine.com]

    Severe generalized abdominal pain, diffuse pulmonary infiltrates, ileus, shock, and meningitis or sepsis due to gram-negative bacilli may occur. See the image below. Strongyloides eggs in native examination from feces of a newborn. [emedicine.medscape.com]

  • Necator Americanus

    Hookworm, Ancylostoma duodenale, and Necator americanus. Juveniles in the soil can burrow into human skin. The eggs are usually eaten along with food. However, it appears that hookworm infections in humans are not always totally bad news! [bumblebee.org]

    Types of Roundworms There are a number of different species of roundworms but the most common ones to infect humans include: Ascaris lumbricoides (most common roundworm infections in humans) Hookworms ( Ancylostoma duodenale and Necator americanus ) Guinea [healthhype.com]

  • Liver Biopsy

    Diagnosis is made by identifying the parasite or eggs in a liver biopsy. Treatment is usually with thiabendazole or albendazole. Enterobiasis Enterobius vermicularis (the threadworm) is cosmopolitan. [oxfordmedicine.com]

Treatment The treatment of choice is ivermectin, 150 5g/kg orally as a single dose, which kills microfilariae but is less effective against adult worms. Treatment is repeated at 3-mo intervals for 2-3 years. [antiinfectivedrugs.com]

Prevention is by properly cooking fish. Hepatic capillariasis—caused by Capillaria hepatica, a parasite of rats. Ingested eggs hatch and larvae pass to the liver and cause a syndrome similar to visceral larva migrans (see below). [oxfordmedicine.com]

Prevention Because transmission depends on mosquito vectors, control measures are directed at reducing mosquito populations and reducing the number of bites by mosquitoes. [antiinfectivedrugs.com]

Prevention Control of blackfly by spraying. Mass distribution of ivermectin. [patient.info]

Care should be taken to practice preventative measures before the nematode population increases and infests the entire field. [blog.agrivi.com]

As will be explained further, eradication of the disease is relatively simple and is in near sight--eradication can be accomplished simply by preventing people from drinking from water contaminated by the parasite. [web.stanford.edu]
