Infectious and parasitic diseases

Bejel

Bejel is a unique type of tropical treponematosis, observed mainly in children in Arab countries and manifested by lesions of the skin at various stages, and of the skeletal system at later stages.

Yaws (synonym: tropical syphilis) is the most widespread highly contagious treponematosis, in which, in addition to the skin and mucous membranes, the skeletal system is also involved in the pathological process.

Migrating larva (larva migrans): causes, symptoms, diagnosis, treatment

Very close in clinical manifestations to linear migratory myiasis is "migrating larva" (larva migrans) - a skin disease caused by the larva of intestinal worms, most often hookworms (Ancylistoma brasiliense, A. ceylonicum, A. caninum). All these parasites are intestinal worms of animals, primarily dogs and cats.

Linear migratory miasis: causes, symptoms, diagnosis, treatment

Linear migratory myiasis is found both in the tropics and in temperate countries, including Russia. Linear migratory myiasis in temperate climates is most often observed in the summer. Female gadflies lay eggs, attaching them to the hair of horses or cattle.

Deep skin myiasis: causes, symptoms, diagnosis, treatment

The group of deep myiases (myasis cutis profunda) includes diseases that differ in etiology and clinical course, the unifying factor of which is the deep penetration of larvae into the dermis, subcutaneous fat and underlying tissues. Deep myiases are characterized by malignancy.

Superficial skin myiasis: causes, symptoms, diagnosis, treatment

Diseases of the superficial skin myiasis are relatively benign. This is due to the fact that the larvae, not being able to digest living, i.e. normal tissue, are limited to devouring pus and decomposed necrotic tissue.

Buruli ulcer: causes, symptoms, diagnosis, treatment

The nosological independence of Buruli ulcer due to its fairly typical clinical and epidemiological features is recognized by most authors. Buruli ulcer was named in the 60s of the last century, when a large number of its observations were first described as a local epidemic in Uganda in the province of Buruli.

Trophic ulcers: causes, symptoms, diagnosis, treatment

Tropical ulcer is a persistent and sluggish ulcerative process with a dominant localization on the skin in the ankle joint area and, less often, the lower third of the leg, which occurs more often in children, young and middle-aged men living in tropical and subtropical climates. As synonyms, tropical ulcer is sometimes called phagedenetic, scabby, jungle, Madagascar, etc.

Tropical mycoses: causes, symptoms, diagnosis, treatment

Mycotic skin lesions are a very significant practical problem, both because of their extreme prevalence and their known contagiousness. This is even more true for tropical dermatomycoses, which, like all tropical pathology, can be divided into tropical mycoses proper

Dracunculiasis: causes, symptoms, diagnosis, treatment

Dracunculiasis is a biohelminthiasis. Mature individuals are localized in the subcutaneous tissue, most often in the lower extremities. The causative agent of dracunculiasis is Dracunculus medinensis, a guinea worm with clearly expressed sexual dimorphism.
