Cavernous carotid aneurysms rarely cause subarachnoid hemorrhage or major neurologic morbidity.
To determine whether aneurysms of the cavernous internal carotid artery (CCA) cause major neurologic morbidity or death. ⋯ CCA is a disorder with strong female gender bias that uncommonly causes major neurologic complications. These data suggest that CCA should not be included in analyses that determine the risk of severe neurologic morbidity, hemorrhage, or death due to intracranial aneurysms.

Recent reports indicate that several descriptors of pain sensations in the McGill Pain Questionnaire (MPQ) are difficult to classify within MPQ sensory subcategories because of incomprehension, underuse, or ambiguity of usage. Adopting the same methodology of recent studies, the present investigation focused on the affective and evaluative subcategories of the MPQ. ⋯ Despite notable changes in classification, the intensity ratings of the retained words correlated very highly with those originally reported for the MPQ. In conclusion, although the intensity ratings of MPQ affective and evaluative descriptors need no revision, selective reduction and reorganization of these descriptors can enhance the efficiency of this approach to pain assessment.

Previous studies have established that the activation of peripheral nociceptors alters the central processing of nociceptive stimuli. In this study, we examined whether noxious heating of the dental pulp enhances the nociceptive jaw-opening reflex (JOR) and the expression of the immediate early gene c-fos in chloral hydrate/pentobarbital-anesthetized ferrets. We hypothesized that the application of noxious heat to the dental pulp, a procedure that evokes a preferential activation of pulpal C-fibers, will enhance JOR responses to electrical stimulation of the tooth pulp and that this enhanced response will be associated with the expression of Fos protein in discrete regions of the trigeminal nucleus. ⋯ The enhancement in JOR responses was independent of temporal summation of the electrical stimulus for test stimuli delivered at either 1.0 or 0.1 Hz. Sensitization of the JOR was associated with an increase in the number of immunohistochemically identified Fos-positive nuclei in trigeminal caudalis (Vc) and the transition zone between trigeminal interpolaris and caudalis (Vi/Vc) ipsilateral to the site of stimulation compared with sham stimulated animals. These findings suggest that neuronal populations in Vc and Vi/Vc play a role in the enhanced reflex responses to tooth pulp stimulation and may contribute to the pain and hyperalgesia associated with a symptomatic pulpitis.

The cancer patient presents special challenges to the anesthesiologist. Cancer may have multiple effects including those due to the primary tumor, metastases, the effects and toxicity of cancer therapy, associated paraneoplastic and physiologic responses to the tumor and the strong psychological responses elicited by cancer. ⋯ Patient education and reassurance regarding issues of safety, pain control and respect for patient preferences are important goals as well. This review provides the anesthesiologist with both general and specific information important to the systematic and complete preoperative evaluation of the patient with cancer.

The European Board for Accreditation in Cardiology (EBAC) is a joint initiative of the European Society of Cardiology (ESC) and the Cardiology Section of the Union of European Medical Specialists or Union Européenne des Médecins Spécialistes (UEMS). EBAC operates independently from these parent organisations. The ESC is the highest cardiovascular scientific authority in Europe and the most important provider of Continuing Medical Education (CME) in cardiology. ⋯ EBAC was founded in 2000. EBAC accreditation is complimentary to national CME accreditation. The Netherlands Society of Cardiology (Nederlandse Vereniging voor Cardiologie, NVVC) and its Institute for CME, the Netherlands Institute for Continuing Cardiovascular Education (Cardio-Vasculair Onderwijs Instituut, CVOI) formally recognise EBAC accreditation and Attendance Certificates.
