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]

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]

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]

• Periorbital Edema

  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]

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]

Treatment is usually with thiabendazole or albendazole. Enterobiasis Enterobius vermicularis (the threadworm) is cosmopolitan. [oxfordmedicine.com]

Treatment If asymptomatic then no treatment is required. Otherwise, either diethylcarbamazine or ivermectin is effective. [patient.info]

Prognosis Prognosis depends on the stage at which the infection is treated. If treated early during the course of the disease, the corneal opacities may be minimal and may recede with appropriate treatment. [eyewiki.aao.org]

Surgery Surgical interventions can be directed at the underlying etiology of vision loss. Cataract extraction can be performed on visually significant cataracts induced by the disease process. [eyewiki.aao.org]

Epidemiology It is estimated that 2-13 million humans are infected with the Loa loa larvae. [patient.info]

Epidemiology Trichinella occurs worldwide with the cycle maintained in several different mammalian species. The mammal serves as the definitive host for the adult worm and the intermediate host for the encysted larvae. [clinicalgate.com]

Pathophysiology The multiple sequelae result from direct invasion of the nematodes, which leads to induction of inflammation in the infected host. [eyewiki.aao.org]

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]

Prevention (Sanitation and Exclusion) Use certified clean, nematode-free seed. Stem nematode is not seedborne, but can live on alfalfa chaff. [ipm.ucanr.edu]

However, the focus should also be on prevention to avoid a recurrence of the infection. The worms do not have to be removed surgically unless large number of worms are causing an obstruction, or other complications. [healthhype.com]
