OBJECTIVE: The aim of our blinded retrospective study was to evaluate the diagnostic performance of the Subaxial Cervical Spine Injury Classification (SLIC) System in predicting the need for surgical intervention after subaxial cervical spine injury; SLIC scores were determined using CT alone or both CT and MRI. MATERIALS AND METHODS: Patients were included if they had injuries that were subaxial (C3-C7), if they had undergone CT and MRI within 48 hours of admission, if they were either treated surgically or had sufficient clinical documentation describing nonsurgical management (halo device or hard collar), and if the SLIC neurologic score could be determined from a documented neurologic examination...

CPR in a diving bell is difficult. It is taught by diving companies and training institutes but has not been subjected to the tenets of evidence based medicine. The diving bell lacks space as well as a flat hard surface to lay the patient on and therefore conventional methods of administering CPR are not possible. The diver is hung from a pulley tied to the diver's harness, and the bell flooded with water to reduce pooling of blood. Airway is established using a cervical collar to hyperextend the neck and inserting an appropriate oropharyngeal airway...

Treatment of polytrauma patients has been discussed extensively during the past decades. Management in the prehospital phase, on admission, and in the early postoperative/ICU-period has to refer to injury severity, priority of injuries, and likelihood of development of multi organ failure. Cervical spine injuries are reported in 4-34% of polytrauma cases. Securing the cervical spine by a hard collar is one of the basic procedures in the prehospital phase. Different strategies of assessing the cervical spine are still discussed controversially...

BACKGROUND: Formaldehyde is a widely used organic compound, used in several applications (hard thermoset resins, adhesives, disinfectants, tissue fixatives, etc), in its free form or released by formaldehyde releaser products. Its use is under control due to its toxic, carcinogenic, and allergenic properties. OBJECTIVE: The aim of this study was to investigate the frequency of formaldehyde sensitization, time trend, and correlation to occupations. METHODS: This study is a cross-sectional study on a population of 23,774 patients tested from 1996 to 2012 in Northeastern Italy...

Although the calcitic hard parts of belemnites (extinct Coleoidea) are very abundant fossils, their soft parts are hardly known and their mode of life is debated. New fossils of the Jurassic belemnitid Acanthoteuthis provided supplementary anatomical data on the fins, nuchal cartilage, collar complex, statoliths, hyponome and radula. These data yielded evidence of their pelagic habitat, their nektonic habit and high swimming velocities. The new morphological characters were included in a cladistic analysis, which confirms the position of the Belemnitida in the stem of Decabrachia (Decapodiformes)...

Understanding animal movement behaviour is key to furthering our knowledge on intra- and inter-specific competition, group cohesion, energy expenditure, habitat use, the spread of zoonotic diseases or species management. We used a radial basis function surface approximation subject to minimum description length constraint to uncover the state-space dynamical systems from time series data. This approximation allowed us to infer structure from a mathematical model of the movement behaviour of sheep and red deer, and the effect of density, thermal stress and vegetation type...

Pregnant women, when employed in physically demanding occupations, may encounter difficulties in carrying out their work throughout pregnancy. Many such "blue collar" workers are unable to proceed in strenuous work during advanced stages of pregnancy. However, scientific evidence is not sufficient to support the widely accepted assumption of health risks due to the hard work during pregnancy. Therefore, in Israel, as long as pregnancy is normal, and the good health of both the mother and fetus is maintained, such workers are not entitled to sick leave or any other form of compensation...
