The linear dermatitis of "larva currens" is a typical manifestation of strongyliasis, however is generally too unrecognized. It is observed in about 7% of cases, more frequent in white race. Due to the migration of Strongyloides larvae in epidermis of sensitized person, it appears in form of rectilinear urticaria from 10--30 cm, developed from 12--48 hours and disappeared without leaving any trace. It can appear at any place of the body, sometimes in many places simultaneously. The total duration of the evolution similiar to that of strongyliasis can be developed during a many tenth of years. In reality the differential diagnosis is easy with filariasis (loa-loa) and specially with cutaneous larva migrans (ankylostomiasis, creeping eruption, larbish). The thiabendazole cures the strongyliasis nad its cutaneous manifestations in 85% of cases with a single oral dose of 6 tablets 6 x 250 mg).

The full spectrum of skin diseases related to travel in tropical areas is unknown. We prospectively studied 269 consecutive patients with travel-associated dermatosis who presented to our tropical disease unit in Paris during a 2-year period. The median age of these patients was 30 years; 137 patients were male; 76% of the patients were tourists; 38% had visited sub-Saharan Africa; and 85% had been appropriately vaccinated against tetanus. Cutaneous lesions appeared while the patient was still abroad in 61% of cases and after the patient's return to France in 39%. The diagnosis was definite in 260 cases; 137 of these cases (53%) involved an imported tropical disease. The most common diagnoses were cutaneous larva migrans (25%); pyodermas (18%); pruritic arthropod-reactive dermatitis (10%); myiasis (9%); tungiasis (6%); urticaria (5%); fever and rash (4%); and cutaneous leishmaniasis (3%). Hospitalization was necessary in 27 cases (10%), with a median duration of 5 days (range, 2-21 days). Travelers should be advised on how to avoid exposure to the agents and vectors of infectious dermatoses. Travel first-aid kits should include insect repellents and antibiotics effective against bacterial skin infections.

The aim of this work was to study cross-reactivity in the diagnosis of two related ascaridosis. Nineteen patients diagnosed with recidivous acute urticaria (RAU) caused by Anisakis simplex and 26 patients diagnosed with visceral larva migrans (VLM) caused by Toxocara canis were studied employing commercial diagnostic kits and "in house" assay kits. Cross-reactivity observed was greater when using "in house" assay kits, suggesting that T. canis excretory-secretory antigens were not only recognized by antibodies from patients with RAU but with greater intensity compared to the A. simplex excretory-secretory antigens.

Climate change contributes to the increase in severity and frequency of flooding, which is the most frequent and deadly disaster worldwide. Flood-related damage can be very severe and include health effects. Among those health impacts, dermatological diseases are one of the most frequently encountered. Both infectious and noninfectious dermatological conditions are increasing after flooding. We searched PubMed using the search term climate change OR global warming OR rainfall OR flooding OR skin. Articles published in the English-language literature were included. We also searched the International Society of Dermatology website library on climate change for additional articles. There is an increased risk of trauma during the course of a natural disaster. The majority of post-tsunami wound infections were polymicrobial, but gram-negative bacteria were the leading causes. Infectious diseases with dermatological manifestations, such as impetigo, leptospirosis, measles, dengue fever, tinea corporis, malaria, and leishmaniasis, are important causes of morbidity among flood-afflicted individuals. Insect bites and stings, and parasite infestations such as scabies and cutaneous larva migrans are also frequently observed. Inflammatory conditions including irritant contact dermatitis are among the leading dermatological conditions. Dermatological conditions such as alopecia areata, vitiligo, psoriasis, and urticaria can be induced or exacerbated by psychological conditions post disaster. Prevention is essential in the management of skin diseases because of flooding. Avoiding exposure to contaminated environments, wearing protective devices, rapid provision of clean water and sanitation facilities, prompt vector controls, and education about disease risk and prevention are important.
