1/71. larva migrans within scalp sebaceous gland.

    A case of larva migrans or serpiginous linear dermatitis on the scalp of a teenager is reported. An ancylostomid larva was found within a sebaceous gland acinus. The unusual skin site for larva migrans as well as the penetration through the sebaceous gland are highlighted. The probable mechanism by which the parasite reached the skin adnexa is discussed.

2/71. Case studies in international travelers.

    family physicians should be alert for unusual diseases in patients who are returning from foreign travel. malaria is a potentially fatal disease that can be acquired by travelers to certain areas of the world, primarily developing nations. Transmitted through the bite of the anopheles mosquito, malaria usually presents with fever and a vague systemic illness. The disease is diagnosed by demonstration of plasmodium organisms on a specially prepared blood film. Travelers can also acquire amebic infections, which may cause dysentery or, in some instances, liver abscess. amebiasis is diagnosed by finding entamoeba histolytica cysts or trophozoites in the stool. Invasive amebic infections are generally treated with metronidazole followed by iodoquinol or paromomycin. Cutaneous larva migrans is acquired by skin contact with hookworm larvae in the soil. The infection is characterized by the development of itchy papules followed by serpiginous or linear streaks. Cutaneous larva migrans is treated with invermectin or albendazole. Case studies are presented. ( info)

3/71. Souvenir from the Hamptons - a case of cutaneous larva migrans of six months' duration.

    Cutaneous larva migrans is a distinctive serpiginous eruption caused by a reaction to burrowing hookworms. The infection is usually self-limited, normally lasting 2-8 weeks, but may persist for more than a year if misdiagnosed. Biopsies of the creeping eruption rarely reveal an organism. Thus, it is important for the infection to be recognized clinically, so that effective treatment may begin. We found topical thiabendazole to be fast and effective in treating this case of cutaneous larva migrans of six months' duration. ( info)

4/71. Abnormal migration of ascaris into the middle ear.

    ascaris in the middle ear is very rare with very few cases having been reported. We report here two such cases with different presentations. ( info)

5/71. Raccoon roundworm (Baylisascaris procyonis) encephalitis: case report and field investigation.

    Baylisascaris procyonis is a common and widespread parasite of raccoons in the united states and canada. With large raccoon populations occurring in many areas, the potential risk of human infection with B procyonis is high. We report a case of severe raccoon roundworm (B procyonis) encephalitis in a young child to illustrate the unique clinical, diagnostic, and treatment aspects, as well as public health concerns of B procyonis infection. Acute and convalescent serum and cerebrospinal fluid samples from the patient were tested for antibodies against B procyonis to assist in documenting infection. An extensive field survey of the patient's residence and the surrounding community was performed to investigate raccoon abundance and to determine the extent of raccoon fecal contamination and B procyonis eggs in the environment. The patient evidenced serologic conversion, and the field investigation demonstrated a raccoon population far in excess of anything previously reported. There was abundant evidence of B procyonis eggs associated with numerous sites of raccoon defecation around the patient's residence and elsewhere in the community. Because B procyonis can produce such severe central nervous system disease in young children, it is important that pediatricians are familiar with this infection. The public should be made aware of the hazards associated with raccoons and B procyonis to hopefully prevent future cases of B procyonis infection. ( info)

6/71. Five cases of ocular toxocariasis confirmed by serology.

    We report 5 cases of ocular toxocariasis in Korean adults complaining of visual impairment along with floating or bubbling sensation. Fundoscopic examination revealed a retinal detachment along with exudate in 4 cases. They all showed typical reaction by ELISA and immunoblot against Toxocra excretory-secretory antigen. One case showed high level of anti-toxocara IgE antibodies (34,000 toxocara units/L) as well as increased level of serum total IgE antibodies and the specific IgE antibodies for 3 inhalant antigens, suggesting that high level of anti-toxocara IgE antibodies was associated with an atopic status. Clinical manifestations were improved after the sequential use of steroids then mebendazole. We also suggest that ocular toxocariasis should be thoroughly investigated even when an evocative uniocular inflammatory lesion is encountered in peripheral retina without a systematic disease.

7/71. Two imported cases of cutaneous larva migrans.

    Cutaneous larva migrans (CLM) is a rare serpiginous cutaneous eruption caused by accidental penetration and migration in the skin with infective larvae of nematode that normally do not have the human as their host. Although CLM has a worldwide distribution, the infection is most frequent in warmer climates. More recently, they have been increasingly imported from the tropics or subtropics by travelers. We experienced two patients who had pruritic serpiginous linear eruption in their skin for a few weeks after traveling to the endemic areas (brazil and thailand, respectively). After the treatment with albendazole, the skin lesions resolved with post-inflammatory hyperpigmentation. We report herein two cases of cutaneous larva migrans successfully treated with albendazole.

8/71. Cutaneous larva migrans contracted in england: a reminder.

    We report a case of cutaneous larva migrans contracted in england. This case serves as a reminder that the lack of travel abroad should not preclude the diagnosis. We discuss clinical presentation and management of cutaneous larva migrans. ( info)

9/71. Treatment of widespread cutaneous larva migrans with thiabendazole.

    Cutaneous larva migrans (CLM) is a characteristic eruption that is caused by penetration and migration in the skin of nematode larvae. Both animal and human hookworms have been implicated in the pathogenesis of the condition, with ancylostoma braziliensis and A. caninum being the most common among them. CLM is quite common in tropical areas, but, due to travelling, several cases have also been described in europe. We present a patient with CLM who presumably contacted the disease during a holiday in singapore. The patient was treated successfully with oral thiabendazole. ( info)

10/71. One confirmed and six suspected cases of cutaneous larva migrans caused by overseas infection with dog hookworm larvae.

    Cutaneous larva migrans (CLM) is characterized as creeping eruption/serpiginous erythema and/or mobile erythematous induration on the skin. In japan, gnathostoma spp. are the most well known pathogens causing CLM, especially the creeping eruption type. Recently, spirurina type X larvae have been added to the list of causative agents for creeping eruption in japan. Here we report one confirmed and 6 suspected cases of creeping eruption caused by infection with dog hookworm larvae. The patients were assumed to have been infected overseas. Dog hookworms such as ancylostoma caninum and A. brasiliense should be considered as possible causative agents for creeping eruption, especially when the patients have a history of travelling overseas.
