Dermoglandular advancement-rotation flap for conservative treatment of breast cancer – description of technique, objective and subjective assessments

Objectiveto describe and evaluate the dermoglandular advancement-rotation flap with no contralateral surgery as a technique for the conservative treatment of breast cancer when skin or a large proportion of gland requires resection.Patients/Methods14 patients with breast tumors with a mean size of 4.2 cm and need for skin resection. The resection area is included within an isosceles triangle, with its apex located on the areola, which is the pivot for rotation of a dermoglandular flap released through a lateral extension along that triangle base. Symmetry before and after radiotherapy was objectively assessed by authors using the BCCT.core software, as well as subjectively by three experts and patients themselves using the Harvard scale.ResultsExperts considered the breast symmetry results to be excellent/good for 85.7% of patients in the early post-operative period and 78.6% in the late post-operative period. Excellent/good ratings provided by BCCT.core software amounted to 78.6% of cases in the early post-operative period and 92.9% in the late post-operative period. Symmetry was rated as excellent/good by 100% of patients.ConclusionDermoglandular advancement-rotation flap technique with no contralateral surgery provides good symmetry when a large proportion of skin or gland requires resection on breast conservative cancer treatment

ATLANTIC-CAMTRAPS: a dataset of medium and large terrestrial mammal communities in the Atlantic Forest of South America

Our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. Camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. Here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the Neotropical region based on camera trapping studies. The dataset comprises 170 surveys of medium to large terrestrial mammals using camera traps conducted in 144 areas by 74 studies, covering six vegetation types of tropical and subtropical Atlantic Forest of South America (Brazil and Argentina), and present data on species composition and richness. The complete dataset comprises 53,438 independent records of 83 species of mammals, includes 10 species of marsupials, 15 rodents, 20 carnivores, eight ungulates and six armadillos. Species richness averaged 13 species (±6.07 SD) per site. Only six species occurred in more than 50% of the sites: the domestic dog Canis familiaris, crab-eating fox Cerdocyon thous, tayra Eira barbara, south American coati Nasua nasua, crab-eating raccoon Procyon cancrivorus and the nine-banded armadillo Dasypus novemcinctus. The information contained in this dataset can be used to understand macroecological patterns of biodiversity, community, and population structure, but also to evaluate the ecological consequences of fragmentation, defaunation, and trophic interactions. © 2017 by the Ecological Society of Americ

Nódulos benignos da mama: uma revisão dos diagnósticos diferenciais e conduta Benign breast masses: a review on diagnosis and management

Os nódulos mamários benignos são responsáveis por até 80% das massas palpáveis. Seu diagnóstico diferencial é amplo, envolvendo os cistos mamários, os fibroadenomas, os tumores filóides, os papilomas, os lipomas, os hamartomas e os adenomas, entre outros. O fibroadenoma é a neoplasia mamária mais comum em pacientes menores de 35 anos e os cistos são mais freqüentes na perimenopausa. O diagnóstico diferencial entre nódulos sólidos ou císticos poderá ser feito por meio da punção aspirativa com agulha fina ou pela ultra-sonografia, sendo terapêutica para os últimos. Neste artigo serão revisados os aspectos diagnósticos diferenciais entre estes tumores e as novas abordagens terapêuticas.<br>The benign mammary tumors are responsible for up to 80% of the clinical masses. Its differential diagnosis is wide, involving mammary cysts, fibroadenomas, phyllodes tumors, papillomas, hamartomas, and adenomas, among others. The fibroadenoma is the most common mammary neoplasia in patients under 35 years old, while the cysts are more frequent in the perimenopause. The differential diagnosis among solid or cystic nodules can be made through the fine-needle aspiration or by ultrasound, being therapeutic for the last ones. In this article, the differential diagnostic aspects will be revised between these tumors, as well as the new therapeutic approaches
