Cisto pilonidal sacrococcígeo: resultados do tratamento cirúrgico com incisão e curetagem Pilonidal sinus: surgical treatment results with incision and curettage

duzentos e treze doentes com cisto pilonidal sacrococcígeo foram submetidos a tratamento cirúrgico pela técnica de incisão e curetagem, no período de janeiro de 1997 a dezembro de 2006. Foram avaliados o sexo, a idade o tipo de anestesia, o tempo de internação, período de cicatrização, complicações e seguimento. Conclui-se que a técnica de incisão e curetagemé uma boa opção no tratamento cirúrgico do cisto pilonidal sacrococcígeo, proporcionando tempo aceitável de cicatrização e baixos índices de recidiva.<br>From January 1997 to December 2006, 213 patients with pilonidal sinus have undergone on surgical treatment with incision and curettage technique. We analyzed age, sex, the anesthetic and surgical procedures, recovery as well as healing time and follow up. We have concluded that incision and curettage in surgical treatment of pilonidal sinus is a good option, with quick recovery and an acceptable healing time

Linfangioma perineal: relato de caso Perineal lymphangioma: a case report

O linfangioma é uma neoplasia benigna que pode se manifestar em qualquer local do corpo, sendo a localização perineal ou retrorretal bastante incomuns. Apresenta sintomatologia inespecífica, podendo manifestar-se de diversas formas, como o abaulamento perineal e compressão de estruturas pélvicas. Relata-se um caso de linfangioma perineal com ênfase em seu tratamento já que esta entidade clínica, apesar de benigna, tem potencial de malignização.<br>Lymphangioma is a benign neoplasm that can manifest anywhere in the body. The perineal or retrorectal localization is very uncommon. It presents unspecific symptomatology such as compression and displacement of pelvic structures. A case of perineal lymphangioma is reported emphasizing its treatment considering that they are benign tumors with malignant potential

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.
