Distribuição da leishmaniose tegumentar por imagens de sensoreamento remoto orbital, no Estado do Paraná, Brasil

BACKGROUND: The epidemiology of tegumentary Leishmaniasis (TL) is poorly known in the State of Parana. OBJECTIVES: To verify the geographical distribution of TL cases in four municipalities in the State of Parana and correlate the notified TL cases with the presence of the remaining vegetation and water streams, using images by satellite monitoring. METHODS: The distribution of 4,416 cases of TL in the State of Parana, from 1993 to 1998, was done according to the notification records used by the State of Parana Health Secretariat. The distribution of 231 cases of TL and the correlation between these cases and the remaining forest, as well as the extent to which man has influenced the environment in Cianorte, Japura, Jussara and Sao Tome municipalities was verified using satellite monitoring. RESULTS: The geographical distribution showed a higher concentration of cases in the northern and western regions of Parana. The satellite monitored images show that there is a close relationship between TL and modified native forest areas, gallery forest areas or the remainder of both. CONCLUSION: It is possible that the areas with higher incidence of TL in Parana are similar to the ones in Cianorte, Japura, Jussara and Sao Tome municipalities.

Pyoderma gangrenosum: skin grafting and hyperbaric oxygen as adjuvants in the treatment of a deep and extensive ulcer

Pyoderma gangrenosum is a rare dermatosis of unknown etiology and variable clinical presentation. The disease is challenging for the medical staff, from the frequent diagnostic difficulties to the lack of scientific evidence with a good level to support the management of extensive and refractory cases. Our patient is a 50 year-old man with an extensive and deep ulcer on the left leg, which exemplifies the therapeutic difficulties inherent to the disease and who, fortunately, has progressed with excellent result after association of hyperbaric oxygen therapy and skin grafting to the immunosuppression therapy initially proposed.

Disidrose: aspectos clínicos, etiopatogênicos e terapêuticos

Dyshidrotic eczema (pompholyx) is a common, nonspecific, acute, recurrent or chronic vesicular eczematous eruption of the palms, soles, and lateral aspects of the fingers. Treatment is difficult and success depends on the recognition and elimination of the etiologic agent. Although the cause of dyshidrotic eczema is unknown, emotional stress, drugs, and various substances contacting the skin are implicated in its origin. Corticosteroids are useful in the management of dyshidrotic eczema, but new drugs and therapies have been indicated for refractory and/or more severe cases.
