Use of a flexible tip bougie (FlexTip) in the management of the first-attempt failure intubation with the C-MAC D-Blade videolaryngoscope in the intensive care unit: A prospective, case series.

We describe a series of 11 cases in which we used the new flexible tip (FlexTip) bougie as a rescue device following first-attempt failure at intubation with the C-MAC D-Blade video laryngoscope in our UCI. We collected data from all intubations performed using the C-MAC D-Blade video laryngoscope over a 16-month period. Ninety six patients were included in the study: 79 (86.8%) were intubated at the first attempt; 11 (12.1%) required 2 attempts; and 1 patient required 3 attempts. The Frova Intubating Introducer was used in 1 of the 12 patients requiring more than 1 intubation attempt, and the FlexTip was used in the remaining 11. This study shows that the new FlexTip bougie is a good rescue device when the first attempt at video laryngoscope intubation fails.

Reproductive biology of Syagrus coronata (Arecaceae): sex-biased insect visitation and the unusual case of scent emission by peduncular bracts.

Several monoecious species of palms have developed complex strategies to promote cross-pollination, including the production of large quantities of floral resources and the emission of scents that are attractive to pollinators. Syagrus coronata constitutes an interesting model with which to understand the evolution of plant reproductive strategies in a monoecious species adapted to seasonally dry forests. We monitored blooming phenology over 1 year, during which we also collected and identified floral visitors and putative pollinators. We identified potential floral visitor attractants by characterizing the scent composition of inflorescences as well as of peduncular bracts, during both male and female phases, and the potential for floral thermogenesis. Syagrus coronata produces floral resources throughout the year. Its inflorescences are predominantly visited by a diverse assortment of small-sized beetles, whose richness and abundance vary throughout the different phases of anthesis. We did not find evidence of floral thermogenesis. A total of 23 volatile compounds were identified in the scent emitted by the inflorescences, which did not differ between male and female phases; whereas the scent of the peduncular bracts was composed of only 4-methyl guaiacol, which was absent in inflorescences. The composition of floral scent chemistry indicates that this palm has evolved strategies to be predominantly pollinated by small-sized weevils. Our study provides rare evidence of a non-floral scent emitting structure involved in pollinator attraction, only the second such case specifically in palms. The peculiarities of the reproductive strategy of S. coronata might play an important role in the maintenance of pollination services and pollen dispersion.

Contrasting Relationship of True Weevils (Curculionidae) and Woody Plants Diversity in Semi-arid Landscape Units.

In general, insect herbivore diversity is positively correlated to plant diversity since plant assemblages structure different microhabitats and provide food resources for such insects. Although poorly studied, insect herbivores in tropical dry forests are positively affected by tree species richness and the structural architecture of vegetation. In this study, we analyzed whether true weevil and woody plants present similar patterns of diversity across different landscape units in a Neotropical tropical dry forests located in Brazil, and if there is a correlation among their assemblages. We used Hill numbers according to species richness and the inverse of Simpson to compare the taxonomic diversity of true weevils and plants in nine landscape units located at the São Francisco river basin in the states of Sergipe and Alagoas, north-eastern Brazil. All trees and shrubs with diameter at breast height (1.3 m) ≥ 5 cm were sampled, and true weevils were collected using a modified Malaise trap. We used co-correspondence analysis to test if plants and true weevil species tend to co-occur. A total of 538 true weevils from 60 species was collected, and a total of 1419 plants belonging to 49 species was recorded. There is no general pattern of co-occurrence and diversity among true weevils and plants, indicating that the plant community is not structuring true weevil assemblage in the Caatinga. However, there was positive relationship between Sibinia sp4 and Fabaceae-Mimosoideae. These results suggest true weevil-plant relationships in the Caatinga differ from that of more mesic ecosystems. Therefore, we observed that the mechanisms that regulate herbivore-plant diversity relationships do not always follow a positive relationship, as observed in previous studies.

[Idiopathic sclerosing peritonitis (ISP). A report of a new case and a review of the literature]. / Peritonitis esclerosante idiopática (P.E.I.). Presentación de un nuevo caso y revisión de la literatura.

Idiopathic sclerosing peritonitis (I.S.P.) is a rare disease, in which the small bowel is encased in a fibrous capsule, with symptoms and signs of intestinal obstruction. A new case of I.S.P. in a 42-year-old man who underwent laparotomy and was reoperated for intestinal obstruction is presented. A jejunal fistula with a favorable outcome occurred in this case. The literature about this entity is reviewed, and 16 cases are collected. This condition is being reported more and more commonly and requires further research to elucidate its unknown mechanism.

[Splenic hydatidosis: presentation of 8 cases and review of the literature]. / Hidatidosis esplénica: presentación de 8 casos y revisión de la literatura.

A retrospective revision of 8 splenic hydatid cyst cases which underwent surgery in our Department over a period of 19 years is presented. Its rareness, clinical and diagnostic aspects, as well as the association to hydatidosis in other organs are pointed out presenting the results of surgical treatment and patients' evolution.
