First report of Kudoa sp. in the palate and pharyngeal musculature of Gobioides grahamae Palmer and Wheeler, 1955 (Perciformes, Gobiidae) from Marajó Island, Brazil / Primeiro registro de Kudoa sp. na musculatura do palato e faringeal de Gobioides grahamae Palmer e Wheeler, 1955 (Perciformes, Gobiidae) da Ilha do Marajó, Brasil

The aim of this study was to describe the first occurrence ofKudoasp. inGobioides grahamae, contributing to the understanding of this group of parasites in the Amazonian ichthyofauna. Forty specimens ofG. grahamaecollected from the natural environment were analyzed. Cysts ofKudoasp. were diffusely distributed through the striated skeletal muscle fibers with severe edema and inflammatory infiltrate composed of lymphocytes were observed in 30% of the specimens. Edema and marked coagulation necrosis of the muscle fibers was associated with infection byKudoasp. spores, which had accumulated inside the skeletal muscle fibers. Although there are no records of foodborne outbreaks caused by Kudoa spp. in Brazil, it is of paramount importance that we evaluate its occurrence, since the consumption of fish, especially raw fish, has increased because of the adoption of Japanese cuisine. To minimize the economic impacts on the fisheries market and the risk of this parasite to public health, it is necessary to initiate a program to monitor the presence of this likely underdiagnosed, emerging parasite.(AU)

O objetivo deste estudo foi descrever a primeira ocorrência de Kudoa sp. em Gobioides grahamae, contribuindo, assim, para a compreensão desse grupo de parasitas na ictiofauna amazônica. Foram analisados 40 espécimes de G. grahamae coletados de ambiente natural. Cistos de Kudoa sp. foram distribuídos difusamente através das fibras musculares esqueléticas estriadas com presença de edema grave e infiltrado inflamatório composto de linfócitos, que foram observados em 30% dos espécimes. Edema e necrose de coagulação acentuada das fibras musculares foram associados com a infecção por esporos de Kudoa sp., acumulados no interior das fibras musculares da faringe. Apesar de não haver registros de surtos de origem alimentar causada por Kudoa spp. no Brasil, é de suma importância a avaliação de sua ocorrência, uma vez que o consumo de peixe, especialmente peixe cru, aumentou por causa da adoção da culinária japonesa. Para minimizar os impactos econômicos no mercado da pesca e o risco desse parasita para a saúde pública, é necessário iniciar um programa para monitorar a presença desse parasita emergente, possivelmente subdiagnosticada.(AU)

Myiasis in palate by Cochliomyia hominivorax.

Myiasis is the infestation of tissues and organs of animals and humans caused by the larvae of certain dipteran flies. It is more common in undeveloped and tropical countries and usually affects elderly patients, persons who are sick, and patients with mental illness. Oral myiasis is a rare pathologic condition and a risk to the patient's life because of its great destructive potential. Therefore, appropriate treatment is necessary. This article aimed to report a case of myiasis caused by Cochliomyia hominivorax in the palate of a patient with primary progressive aphasia, which was successfully treated through mechanical removal of larvae plus administration of ivermectin.

Gingival leishmaniasis in an HIV-negative patient.

Gingival leishmaniasis is unusual and is mainly observed in immunocompromised patients. We report a case involving the palate, uvula, and gingiva of an HIV-negative patient who was initially diagnosed as having paracoccidioidomycosis. The patient underwent a biopsy for parasite isolation and in situ histopathology and immunohistochemistry. The Leishmania spp. were detected in lesions of the uvula and gingiva. Despite the poor state of teeth, the gingival lesions were caused by American tegumentary leishmaniasis (ATL). The gingival lesions presented an intense inflammatory infiltrate permeated by neutrophils. Immunohistochemistry revealed a predominantly lymphocytic infiltrate. The patient responded well to treatment, with no reactivation during follow-up. The rarity of gingival involvement in immunocompetent patients and the need for inclusion of ATL in the differential diagnosis of gingival lesions are discussed.

Mucocutaneous leishmaniasis in a US citizen.

Mucocutaneous leishmaniasis (MCL) is endemic to many areas of Central and South America. A case of MCL in a US citizen is reported here. An ulcer appeared on the patient's left hard palate, years after a working trip to Peru. Punch biopsies of the lesion were obtained, Leishmania promastigotes were isolated by culture and animal inoculation, and the patient was appropriately treated. As this case demonstrates, a patient's travel history is a key element in making a differential diagnosis of oral lesions.

[Infective stomatitis of the palate]. / Localización palatina de las estomatitis infecciosas.

Having on base a wide and selective review of the literature, it has seemed to us interesting to detail the infective pathology on this location or sometimes occurring. This region is, as well will see, the seat of a rich pathology. We pretend on the other hand to reassess the importance of the meticulous examination of the oral cavity in "systemic problems". We describe the palatal infections divided in four groups: bacterial, viral, fungal and parasitory, according to the causal agent. We review the palatine manifestations of other fewer current syndromes as well.

Oral myiasis. A case report.

Myiasis is a disease commonly seen in animals, especially sheep and cattle. The condition is rare in man. A patient with a neglected fractured mandible with superimposed myiasis is reported.

Miasis cavitaria de localización oral / Oral cavity myiasis

Se presenta un caso de miasis cavitaria de localización oral, eventualidad poco frecuente en nuestro medio, en un paciente joven con parálisis cerebral y retardo mental grave. Se efectúa una revisión del tema y se plantea la necesidad de la cirugía como única opción válida en este tipo de miasis
