Clinical use of cryotherapy to treat oral inflammatory hyperplasia

Aims & Objectives: The aim of this study was to evaluate a protocol for clinical use of cryosurgery in the treatment of oral inflammatory hyperplasia. Trans and postoperative pain and duration of surgery were also assessed. Methods: Twelve patients underwent liquid nitrogen cryotherapy with a closed probe. Two 60-second treatment applications were performed, and thawing was allowed to proceed for 2 minutes. Results: Cure of hyperplasia was achieved in six patients (successful group), whereas three patients had no decrease in the size of the lesion (unsuccessful group). Three patients did not return for follow-up. Conclusion: It is possible to conclude that cryosurgery is an effective therapy for up to 12-mm long pedunculated hyperplasias and can be considered an alternative, useful, fast and painless method for treatment of inflammatory hyperplasia

Osteoma Dérmico – Relato de Caso

Osteoma is a benign osteogenic lesion, composed by compact or cancellous bone. Its etiology seems to be unknown but some authors have suggested three theories to its elucidation: developmental; infectious; and traumatic. It presents slow growing and it can be normally found in craniofacial region and rarely in other bones. The diagnosis is made incidentally because there is no pain complaining. It is reported here, the occurrence of this pathology in dermis region, not previously found in literature. A 31 years old man, come to fhe Oral and Maxillofacial Service complaining about a painless swelling in his face. Due to clinical and radiographic findings a possible diagnosis of osteoma in right zygomatic bone region, was made.O osteoma é uma lesão osteogênica benígna que pode ser contituída por osso compacto ou esponjoso. A etiologia parece ser desconhecida, muito embora diversos autores tenham sugerido determinadas origens para justificar sua elucidação, entre as quais: congênita, infecciosa e traumática. Esta lesão apresenta crescimento lento, podendo ser encontrada, normalmente, na região crâniofacial, podendo ocorrer, raramente, em outros ossos. O diagnóstico é feito acidentalmente, uma vez que esta lesão não é acompanhada de alguma queixa de dor. O presente estudo se refere à ocorrência desta patologia em região dérmica, achado que não foi relatado até então na literatura científica. Um homem com 31 anos de idade, procurou o Serviço Bucomaxilofacial queixando-se de edema indolor na face. A combinação entre os achados clínicos e radiográficos fundamentou o diagnóstico de osteoma em região zigomática

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
