Human lagochilascariasis: about three cases found in the Federal District, Brazil

Three new cases of human infection with Lagochilascaris minor are reported. All the patients were from the state of Pará (Brazil), living in rural areas or close to the forest. They were admitted to hospitals in the Federal District due to the presence of abscesses in the region of the neck, ear, mastoid process and, in two of them, to the involvement also of the central nervous system. Microscopic examination of tissue samples taken from the lesions showed sections of eggs and worms--in different evolutive stages--identified as Lagochilascaris minor. Larvae and adult worms obtained from existing fistulae proved also to be of the same species. The three patients were treated with anthelmintic drugs and surgical excision of the lesions, with good clinical results. In two of them, however, relapsing occurred, suggesting that the drugs do not destroy the worm eggs, in spite of the apparent healing of the lesions.Three new cases of human infection with Lagochilascaris minor are reported.

Microscopic examination of tissue samples taken from the lesions showed sections of eggs and worms - in different evolutive stages - identified as Lagochilascaris minor. Larvae and adult worms obtained from existing fistulae proved also to be of the same species. The three patients were treated with autihelmintic drugs and surgical excision of the lesions, with good clinical results. In two of them, however, relapsing occurred, suggesting that the drugs do not destroy the worm eggs, in spite of the apparent healing of the lesions.

Hiperinfecção por Strongyloides stercoralis: relato de caso autopsiado

Asymptomatic infection due to Strongyloides stercoralis may result in potentially fatal disease in immunodepressed patients. A case of Strongyloides stercoralis hyperinfection discovered at autopsy in a 55-year-old man who had been undergoing treatment for multiple myeloma is reported, emphasizing the clinical and pathological findings. One day earlier, he presented severe headache, abdominal pain and oliguria, from which he developed acute respiratory failure and septic shock. Because of difficulty in reaching this diagnosis, empirical treatment before starting immunosuppressive therapy may be the best strategy for preventing hyperinfection by this worm.

Fibroma condromixóide da coluna torácica: Relato de caso e revisão da literatura

A case of chondromyxoid fibroma (CMF) arising from the Sth right costovertebral junction and spreading into spinal canal causing spinal cord compression is presented. A myelotomography revealed a complete block at T5 level. The patient underwent a decompressive laminectomy with removal of an epidural tumor. This specimen was sent for pathological examination and interpreted as a CMF. The patient had a neurological improvement, post operative MRI revealed a spinal cord free of compression, and we decided on the follow up of the case. Two years later there was reccurrence of the tumor. A posterolateral access by costotransversectomy was made and the lesion was resected. The patient had a neurological improvement which persists on the follow up (two years, at present). Clinical, radiologic and histologic findings, surgical management and recurrence are discussed. The pertinent literature is reviewed.
