#1
Chris M Fiacconi, Jane E Kouptsova, Stefan Köhler
Guided by the framework that autonomic feedback shapes emotional experience and other feeling states, we asked whether feeling-of-knowing (FOK) judgments may be influenced by visceral information through interoception. Participants performed a FOK task for previously studied face-name pairs while changes in cardiovascular and facial muscle activity were recorded. Previously studied face cues for which the corresponding name could not be recalled elicited an increased cardiac rate relative to novel face cues...

Myotonic dystrophy, or Steinert's disease, is the most common form of muscular dystrophy that occurs in adults. This multisystemic form involves the skeletal muscles but affects also the eye, the endocrine system, the central nervous system, and the cardiac system. The weakness of the facial muscles causes a characteristic facial appearance frequently associated with malocclusions. Young people with myotonic dystrophy, who also have severe malocclusions, have bad oral functions such as chewing, breathing, and phonation...

We present a case of sub-total cavernous sinus thrombosis secondary to Panton-Valentine leucocidin-associated Staphylococcus aureus pyomyositis of the muscles of mastication in a previously healthy child, who was successfully managed with no residual disease. He was found to have a factor V Leiden heterozygous mutation. We highlight the propensity of PVL-SA to induce venous thrombosis at any site, but with potential for more severe consequences in the head. We highlight pyomyositis as a differential for peri-orbital cellulitis, and discuss the significance of the factor V Leiden mutation...

Facial nerve paralysis can occur due to infection, inflammation, trauma, surgery, and tumors. It leads to facial asymmetry, impaired oral competence, articulation deficits, and psychological problems. Treatment options include physical therapy, static slings, nerve and muscle transfers, blepharoplasty, brow lift, and chemodenervation with botulinum toxin. We report the case of a 66-year-old Caucasian female with permanent facial paralysis following middle ear surgery. The facial asymmetry was treated successfully with botulinum toxin A injection, hyaluronic acid dermal filler injection, and a thread-lift procedure...

Electromyographic activity over the corrugator supercilii (cEMG), the primary facial muscle involved in negative emotions, is increased during the commission of errors on speeded reaction-time tasks. In the present paper, data from two previously published studies were reanalyzed to investigate the reliability and stability of error-related, correct-related, and difference cEMG across increasing numbers of trials. For a modified go/no-go and a flanker task, we found that error-related cEMG was highly stable and reliable in 14 trials, and correct-related cEMG between 56 and 82 trials, respectively...

Gang Chen, Wenjin Wang, Wei Wang, Wei Ding, Xianxian Yang
BACKGROUND: Masseter-to-facial nerve transfer is a highly efficient technique for reanimating paralyzed muscle and has been reported to restore facial symmetry at rest. However, no systematic studies have been performed, and the effects of preoperative droop oral commissure on postoperative symmetry at rest have rarely been reported. METHODS: The authors retrospectively analyzed 35 patients with masseteric-facial nerve anastomosis and assessed the quality and quantity of the dynamic recovery and the oral commissure symmetry at rest...

Jakob Kaiser, Graham C L Davey
According to theories of embodiment enacting a smile or a frown can positively or negatively influence one's evaluations, even without awareness of one's facial activity. While some previous studies found evidence for facial feedback effects, recent replication attempts could not confirm these findings. Are our decisions throughout the day amenable to the state of our facial muscles? We tested the effect of smiling and frowning on the evaluation of emotional sentences describing everyday situations. While most previous studies based their assessment of awareness on verbal debriefing interviews without explicitly defined criteria, we employed a written debriefing questionnaire in order to avoid potential bias when identifying participants' awareness...

Yong Huang, Yian Xing, Hong Wang, Lianhua Chen, Shitong Li
Previous research has indicated that differences in sensitivities to muscle relaxants exist between facial nerve- and somatic nerve-innervated muscles. Here, we report that the 50% inhibitory concentration (IC50) values for rocuronium were significantly larger in the normal orbicularis oris than those in the gastrocnemius. Increased IC50 values and reduced twitch tension were observed after facial nerve injury. The normal orbicularis oris had a smaller muscle fiber cross-sectional area (CSA) and a larger ratio of endplate surface area (ESA) to muscle fiber CSA (ESA/CSA), but no difference was found in the density of nicotinic acetylcholine receptor (nAChR) subunits on endplates between normal orbicularis oris and gastrocnemius...

Brandy L Vanderbyl, Céline Gélinas
Behavioral scales allow for the pain assessment of vulnerable critically ill patients who are unable to self-report. However, validity of the use of such scales is limited in traumatic brain injury patients with an altered level of consciousness as a result of the different way that these patients express pain. Family participation is considered as an important component of pain assessment for those unable to self-report, but research in this area is minimal so far. This study aimed to describe what behaviors family caregivers deemed relevant to pain for patients with a traumatic brain injury with an altered level of consciousness in the intensive care unit...

BACKGROUND: Condylar hyperplasia is a rare bone disease characterised by excessive development of mandibular condyle, which can lead to the development of asymmetric facial deformity together with malocclusion, mandibular deviation, TMJ and masticatory musculoskeletal system dysfunction. There is not a treatment protocol universally accepted. In order to determine the correct management, treatment and intervention timing of these patients, morphological examinations should be coupled with functional assessments...
