ATLANTIC POLLINATION: a data set of flowers and interaction with nectar-feeding vertebrates from the Atlantic Forest

Flowering plant species and their nectar-feeding vertebrates exemplify some of the most remarkable biotic interactions in the Neotropics. In the Brazilian Atlantic Forest, several species of birds (especially hummingbirds), bats and non-flying mammals as well as one lizard feed on nectar, often acting as pollinators and contributing to seed output of flowering plants. We present a dataset containing information on flowering plants visited by nectar-feeding vertebrates sampled at 166 localities in the Brazilian Atlantic Forest. This dataset provides information about 1902 unique interactions among 515 species of flowering plants and 129 species of potential vertebrate pollinators and the patterns of species diversity across latitudes. All plant-vertebrate interactions compiled were recorded through direct observations of visits, and no inferences of pollinators based on floral syndromes were included. We also provide information on the most common plant traits used to understand the interactions between flowers and nectar-feeding vertebrates: plant growth form, corolla length, rate of nectar production per hour in bagged flowers, nectar concentration, flower color and shape, time of anthesis, presence or absence of perceptible fragrance by human, and flowering phenology as well as status of plant's threat status by IUCN classification. For the vertebrates, status of threat by IUCN classification, body mass, bill or rostrum size are provided. Information on the frequency of visits and pollen deposition on the vertebrate's body are provided when available on the original source. The highest number of unique interactions is recorded for birds (1771) followed by bats (110). For plants, Bromeliaceae contains the highest number of unique interactions (606), followed by Fabaceae (242) and Gesneriaceae (104). It is evident the geographical bias of the studies throughout the southeast of the Brazilian Atlantic Forest and the highest efforts directed to flower-hummingbird interactions. However, it reflects a worldwide tendency of more plants interacting with birds than other vertebrate species. The lack of similar protocols among studies to collect basic data limit comparisons among areas and generalizations. Nevertheless, this dataset represents a notable effort to organize and highlight the importance of vertebrate pollinators on this hotspot of biodiversity on Earth and represents the data currently available.

[The use of an automatic stapler in abdominal hysterectomies. Our experience]

One hundred and four patients were randomized into two groups: group 1 (n = 56) included patients in whom used absorbable staples in vaginal cuff closure; group 2 (n = 48) included patients with classical abdominal hysterectomy. Operating time, facility and outcome 6 months later, were evaluated. Greater costs of absorbable staples compared with sutures can readily be counterbalanced by saving allowed by shorter operating time, no peritoneal contamination, minimal tissue trauma and better cuff healing.

Long-term follow-up of Nissen fundoplication

A study of 68 children under 7 years of age, who had had an abdominal approach Nissen operation, with a postoperative follow-up of between 4 and 14 years, is presented. The patients were classified into three groups, according to radiological appearance and cuff site. In the first group (40 patients) the cuff was intraabdominal and competent; in the second group (22 patients) the cuff was partially displaced into the thorax and was competent. 92% of the patients of these groups are currently asymptomatic and none required reoperation. In the third group (6 patients), there was disorganization of the cuff, together with its displacement into the chest, recurrence of symptoms and the authors recommended reoperation. Nissen's operation is an effective treatment for gastrooesophageal reflux in children unresponsive to medical treatment. Although displacement occurs frequently, valve competence is unaffected except in those where the cuff has disappeared and there is herniation into the thorax in which case reoperation is necessary.

[Congenital vesico-vaginal fistula (author's transl)]

The case of a girl of five years with a congenital vesico-vaginal fistula derived from a persistent left mesonephric duct (or Wolffran duct) is described. The only associated malformation found in this patient was a left renal agenesis.
