RESUMO
The common raccoon, Procyon lotor was introduced at the Balearic Islands (Spain) in 2006. Since then, a colonization process has been carried out, with captures of specimens in 24.30% of the surface of the whole Mallorca Island. For the first time, information has been provided on the invasive process of P. lotor in an insular ecosystem. 257 specimens of P. lotor were captured during the period 2007-2018, of them 104 were analysed to estimate population parameters. Demographic data showed that the population had a sex ratio of 1.00:1.21 (males:females), high BMI values and up to 40% of females were lactating when captured. Related to diet data, the composition was mainly the same as previous studies around its natural and introduced distribution area. Plant residues represented the 53.25⯱â¯38.66% followed by invertebrates with 12.22⯱â¯22.54%, inorganic remains with 11.9⯱â¯22.07% and finally the vertebrates with 4.94⯱â¯18.27%. Thus, it is shown how an opportunistic omnivorous species has adapted to the resources provided by the island. Cultivated plants' remains and plastic content in diet evidence that P. lotor is entering in contact with human settlements and agricultural areas. As occurred in other islands where P. lotor was introduced, it is expected that it could become a future problem for the conservation biodiversity in insular ecosystems, as well as for agriculture and human activity. Due to the potential impact on native biodiversity it is necessary to reinforce the implementation of control actions and prevent its expansion to the rest of the island.

The new capacity of X-ray free-electron laser (XFEL) facilities to produce multi-color X-ray femtosecond pulses paves the way to explore ultrafast phenomena in matter induced by X-ray photons. In the present study, we exploit the site-selectivity and the high temporal resolution of a two-color X-ray femtosecond pump-probe sequence to investigate the isomerization of formamide. The pump pulse excites a particular atomic site in the molecule, while the probe pulse captures changes in the chemical environment at a remote atomic site. The response of the system is found to strongly depend on the nature of the excited site, and the core excitation provides selective control over chemical bond breaking. In particular, we show that the N1s â π* transition can induce the isomerization reaction in formamide and demonstrate the possibility to observe in real time hydrogen migration by measuring the chemical shifts with the X-ray probe pulse. This work opens a unique prospect for X-ray-induced photochemistry at XFEL facilities.
RESUMO
Our study was carried out to examine the relationships of the sigmoid sinus, tympanic membrane and digastric ridge with the mastoid segment of the facial nerve. We studied 33 adult temporal bones. The distances among these structures were evaluated according specific landmarks that can be repeated in a simple manner. We found a good relation, in a proportional and lineal order, between these three structures and the facial nerve. This study indicated a correlation between the position of these three structures and the mastoid segment of the facial nerve through a simple morphometric method.

Objetivo: Valorar la importancia epidemiológica y los resultados del tratamiento conservador en aquellos pacientes mayores de 60 años que han sufrido una fractura de cadera. Pacientes: Desde enero a diciembre de 1998 fueron atendidos en nuestro centro 809 pacientes con fractura de cadera, de las cuales 156 fueron tratadas de modo conservador. De éstas, 111 fueron seguidas durante un periodo de estudio de un año o hasta su defunción. Resultados: Epidemiológicamente, los pacientes tratados de modo conservador constituyen el 19,3 por ciento de las fracturas de cadera atendidas en nuestro centro, y su estancia hospitalaria media es de 6,78 días, de lo cual se deriva su importancia. Con el tratamiento ortopédico de estos pacientes, al año de seguimiento se encontró un marcado deterioro funcional respecto de su estado previo. Igualmente mostraron un leve deterioro mental y un 60 por ciento de los pacientes estaban descontentos o no satisfechos con el tratamiento realizado. Las complicaciones más frecuentes fueron la presencia de decúbitos y deformidades en la extremidad afecta. La mortalidad fue máxima en los dos primeros meses, donde sucedieron el 54 por ciento de las defunciones, siendo la mortalidad acumulada al año del 62 por ciento. Conclusiones: Entre los resultados destaca el déficit funcional permanente obtenido con esta pauta de tratamiento, la poca aceptación que los pacientes muestran con el mismo y la alta tasa de mortalidad presentada (AU)

One hundred and ten adult patients suffering from peripheral vertigo were treated in a multifactorial double-blind randomized clinical trial with dotarizine (50 mg b.i.d.) or cinnarizine (75 mg b.i.d.). There was a 60 days clinical follow-up. Results showed that dotarizine was significantly active against the vertigo attacks and its associated symptoms (mainly neurovegetative). The global superiority of dotarizine was confirmed by statistically significant differences between treatments in the improvement of the severity of vertigo, hearing loss in audiometries, global relief of symptoms, disability produced by crises and global assessment by the investigators themselves. No clinically significant unwanted effects were seen in either group on blood pressure, heart rate or analytical parameters. No serious adverse effects to dotarizine were reported. This study confirms the value of dotarizine in the treatment of peripheral vertigo.

BACKGROUND: The aim of this study was to determine the result of partial resection of the soft palate (SPR) as a treatment of the obstructive apnea syndrome during sleep (OASS). METHODS: Fifty-seven patients diagnosed of OASS treated with SPR were studied. The clinical and polysomnographic results prior to surgery and after 6 months were compared. RESULTS: Prior to SPR the 57 patients had a mean index of apnea plus hypopnea per hour of 57 (IAH) and following surgery the same was of 19.2 (p < 0.0001). IAH improved more than 50% in 42 patients (74%), 30 of whom were cured (IAH < or = 10). Daily hypersomnia and snoring disappeared in 58% of the patients and decreased in intensity in most of the remaining cases. The secondary effects observed following SPR were: rhinolalia, nasal fluid reflux, and oropharyngeal disturbances, being present in 32 patients (56%) and permanent, although slight, in only 13 (23%). CONCLUSIONS: Soft palate resection is a good surgical procedure for therapy of obstructive apnea during sleep, with only slight secondary effects.

20 displaced intraarticular fractures of the calcaneus were treated by open reduction and internal fixation. Results were evaluated according to a standardized protocol. With an average follow-up of 5 (2-8) years, results were excellent or good in 15 cases and fair or poor in 5 cases. An accurate radiographic study and CT scanning are essential for understanding these fractures. We feel that restoring calcaneal shape as anatomic as possible, getting an appropriate reduction of the posterior joint surface by a surgical procedure with early mobilization, and delayed weight bearing would be a good option in treatment of these fractures.
