1/8. Subcutaneous myiasis caused by Dermatobia hominis.A case of subcutaneous myiasis caused by the larvae of the Dermatobia hominis fly is described, involving the ankle region of a 25-y-old man who had returned from peru. After removal of 4 larvae from the affected sites, the lesions healed in 2 weeks without further treatment. Because of the increasing number of people travelling to tropical America, physicians in slovenia will have to consider Dermatobia myiasis in the differential diagnosis of furuncular lesions in patients with a relevant travel history.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/8. Imported furuncular myiasis in germany.Furuncular myiasis is a parasitic infestation of human and other vertebrate tissues by fly larvae of primarily two species: Dermatobia hominis (human botfly, t6rsalo, or berne) in mexico and South and central america and Cordylobia anthropophaga (tumbu fly or mango fly) in africa. Cuterebra species (rabbit and rodent botflies) are also rarely reported to cause furuncular myiasis only within the united states. Although these species inhabit different geographic regions and have different life cycles, their clinical presentations can be similar. We describe a case of "imported" human botfly (D. hominis) furuncular myiasis in a U.S. Army soldier stationed in germany. We review the life cycles of human botflies and key aspects of their clinical presentation, differential diagnosis, and various therapeutic modalities. Most physicians may never encounter myiasis and attribute a patient's complaints to an insect bite or skin infection that will heal without treatment. However, the diagnosis of furuncular myiasis should be considered by remembering the basic elements of this condition: recent travel history to the tropics and a sterile, persistent furuncle with sensations of movement and pain.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/8. Stowaways with wings: two case reports on high-flying insects.More people than ever before are traversing continents, either for business purposes or on holiday. Because 3-10 percent of these travelers experience skin, hair, or nail disorders related to these trips there is an increasing likelihood that Western physicians will be expected to treat exotic conditions imported from different countries. tungiasis and furunculoid myiasis are two typical disorders of intertropical regions. They represent nuisances induced by the presence of arthropod larvae or eggs in the skin. We describe a case of tungiasis, caused by the sand flea tunga penetrans (TP), and a case of myiasis, caused by Dermatobia hominis (DH), and briefly discuss the epidemiology, biologic life cycles, vectors, reservoirs, and clinical presentations of these parasites.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/8. Intestinal myiasis in a baby attending a public health clinic.This article describes a case of intestinal myiasis--the presence of fly larvae in the intestines--in a 12-month-old baby. The asymptomatic child was twice treated by her physician for a presumptive diagnosis of pinworm infection. The mother continued to see "worms" in the child's stool and brought her to a public health primary care clinic where she was evaluated by nurse practitioners. Larvae (maggots) of the false stable fly, Muscina stabulans, were identified in each of two stool specimens collected on different days. Examination of stool specimens from other family members showed no larvae. The likely source of the child's infection was over-ripened bananas, which were kept in a hanging basket. No pharmacologic treatment was prescribed, but the parents were instructed to cover the fruit and wash it before consumption. nurse practitioners are encouraged to report suspected cases of myiasis and to work with patients, their families and public health personnel in order to confirm the diagnosis, identify the source and make suggestions to prevent further infestation.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/8. Cutaneous myiasis.Although cutaneous myiasis remains uncommon in north america, any traveler to the tropics may return with this ailment. A history of travel to a tropical country, a persistent pruritic lesion resembling a boil but having a dark central punctum with seropurulent or serosanguineous drainage, and complaints of a crawling sensation in the area of the lesion should lead the physician to consider myiasis. Treatment is directed at prompt removal of the fly maggot by incision and extraction.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
6/8. Intestinal myiasis.With international travel increasing to more rural areas, physicians must be aware of the accidental ingestion of fly ova from contaminated food, which results in the fecal passage of these nondigestible eggs. The purpose of this report is to review this entity.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
7/8. An unexpected surprise in a common boil.Cutaneous myiasis (myia: Greek word for fly) is an infestation of fly maggots in the skin. A case of human botfly (Dermatobia hominis) myiasis presenting to a Canadian emergency department is described. Typically, it presents as an apparent persistently infected skin abscess or insect bite. As the botfly is indigenous only to Central and south america, the condition is unfamiliar to most North American physicians. However, the rapidity of international air travel permits this exotic tropical infestation to present in any region. Obtaining a history of recent travel to an endemic area is the key to making the diagnosis and instituting appropriate treatment.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
8/8. Human infestation with rodent botfly larvae: a new route of entry?A 3-year-old child was infested with two larvae of the rodent botfly (insect order diptera, genus Cuterebra), one on the back and one on the neck. Both larvae produced tracklike lesions in the skin. After week 1, the back lesion did not develop further, but the neck lesion continued to enlarge and formed a boil-like lesion. Despite examination by several physicians, the case was not recognized as myiasis for more than 3 weeks. Details of the case are presented and discussed, including the possibility that infestation resulted from direct deposition of eggs or larvae on the patient.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
