Incidental Diagnosis of Nonfunctional Bladder Paraganglioma

Nonfunctional bladder paragangliomas may present clinical, radiology and pathological features similar to bladder cancer, so knowledge of this generally benign neuroendocrine neoplasm is of great importance to avoid misdiagnosis. We present the case of a patient with no clinical symptoms of paraganglioma and with radiological and cystoscopy examination results suggestive of urothelial carcinoma but with pathological diagnosis of paraganglioma

Interposition of the Appendix for Ureteral Reconstruction in a Patient Treated for Fibrosarcoma

Abstract: The use of the appendix to reconstruct or replace the ureter is a feasible option in different situations. We present the case of ureteral reconstruction by interposition of the appendix in a patient treated for fibrosarcoma with resection of the retroperitoneal mass adhered to the mesentery and the upper third of the right ureter without cleavage plane. After reconstruction, the patient evolved with a urinary fistula that was resolved on the 29th day after conservative treatment. A computed tomography urography 30 days after surgery showed patency of the anastomosis and closure of the fistula. To the best of our knowledge, this is the first description of a patient submitted to ureteral reconstruction by interposition of the appendix in the surgical treatment of fibrosarcoma

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.
