Síndromes paraneoplásicas: o que o cirurgião-dentista precisa saber?

Introduction: the term paraneoplastic is a clinical, biochemical, hormonal, neurological and/or associated disorder with hematologic malignancies, but not directly related to primary tumor invasion and metastasis. Paraneoplatic syndromes may be the first sign of a malignancy. Review of literature: the syndromes that are most commonly related to dentistry are of lambertt-Eaton, Gardner, Cowden disease, Peutz-Jeghers, Sjögren, multiple endocrine neoplasic, multiple neurofibromatosis of Von Recklinghausen, nevoid basal cell carcinoma, acanthosis nigrans and pemphigus paraneoplastic. Conclusion: early diagnosis of malignant neoplasms favors prognosis and paraneoplastic syndromes assist in diagnosis. It is important that surgeons-dentists know these events in order to diagnose them as soon as possible and refer these patients to specialized treatment.

Estudo epidemiológico sobre as perdas reprodutivas em bovinos leiteiros: ocorrência de neospora caninum, brucella abortus, herpesvírus bovino tipo-1 e leptospira spp. em uma propriedade do município de São Carlos-SP

The aim of this work was draw an endemic level of reproductive losses and determine positivity for four infectious agents related to reproductive problems in dairy cattle on a property in São Carlos city. Blood serum samples were collected of 142 breeding animals more than two years old, from which 21.1% showed history of abortions or stillbirths in at least one pregnancy. Immunofluorescent antibody technique, tamponated acidified antigen test, serum neutralization technique and microscopic agglutination test, were used for detection of antibody anti-Neospora caninum, anti- Brucella abortus, anti-Bovine Herpesvirus Type-1 (BoHV-1) and anti-Leptospira spp , respectively. The serological tests carried out showed that 28.9% of the animals had titers greater than or equal to 100 of anti-Neospora caninum. Viral neutralization tests demonstrated that 26.8% of the animals had titers greater or equal to 256 for antibody anti-BoHV-1.Only 7.7% of the animals studied had titers equal to or greater than 100 in the microscopic agglutination test for Leptospira spp. There weren’t observed positive reactions to the tamponated acidified antigen test for diagnosis of bovine brucellosis. The study suggests the presence of BoHV-1, N. caninum and Leptospira spp in contact with dairy cattle property and could be involved in the occurrence of abortions and stillbirths in cattle. Reproductive losses are endemic and implies a possible behavior of chronic infections caused by these microorganisms.
