Objective: The objective of this research was to study the influence of the use of helmet in facial trauma victims of motorcycle accidents with moderate traumatic brain injury. Methods: We retrospectively reviewed the incidence of facial injuries in helmeted and nonhelmeted victims with moderate traumatic brain injury at a referral trauma hospital. Results: The sample consisted of 272 patients predominantly men (94.5%) and between 21 and 40 years old (62.9%). The majority of patients were using helmet (80.1%). The occurrence of facial fractures was most frequent for zygomatic bone (51.8%), followed by mandible (18.8%) and nasal bones (9.2%). Conclusions: Individuals in the most productive age group are most affected, which causes a great loss to financial and labor systems. It is important to take measures to alert the public regarding the severity of injuries likely to occur in motorcycle-related accidents and ways to prevent them.

The objective of this study was to identify, among motorcyclists involved in traffic incidents, the factors associated with risk of injuries. In 2004, in the city of Maringa-PR, it was determined that there were a total of 2,362 motorcyclists involved in traffic incidents, according to records from the local Military Police. Multivariate analysis was applied to identify the factors associated with the presence of injury. A significantly higher probability of injury was observed among motorcyclists involved in collisions (odds Ratio = 11.19) and falls (odds Ratio = 3.81); the estimated odds ratio for females was close to four, and those involved in incidents including up to two vehicles were 2.63 times more likely to have injuries. Women involved in motorcycle falls and collisions with up to two vehicles stood out as a high-risk group for injuries.

The Brazilian Atlantic Forest harbors the world's richest areas of land planarians (Platyhelminthes: Tricladida). Nevertheless, the number of undiscovered species from this biological unit remains seemingly high. Herein we describe Geoplana piriana Almeida & Carbayo, sp. nov. from the state of Rio de Janeiro, and Geoplana tingauna Kishimoto & Carbayo, sp. nov. from the state of Santa Catarina. Each species shows a dorsum with a unique color pattern among Geoplaninae species. Their internal morphology also differs: G. piriana sp. nov. shows a unique combination of features, including an extrabulbar, non-bifurcated prostatic vesicle, a non-folded male atrium, a horizontal, cylindrical penis papilla, a female atrium anteriorly narrowed, and lined with an epithelium with multilayered aspect. Geoplana tingauna sp. nov. possesses a prostatic vesicle constituted of a pair of branches opening into the very distal portion of a tubular, unpaired portion, a feature not seen in other Geoplaninae species.
