RESUMEN
The psychiatric profiles of 50 patients diagnosed with burning mouth syndrome (BMS) were compared to those of 50 age- and sex-matched individuals as the control group. The Symptom Checklist-90-Revised (SCL-90-R) questionnaire was used to evaluate the role of psychological factors in the development of BMS. Somatization, obsessive-compulsive, depression, anxiety, hostility, phobic anxiety, psychoticism, global severity index (GSI), positive symptom total (PST), and positive symptom distress index (PSDI) scores were significantly higher in the patients with BMS than in the control group. In a subgroup analysis according to sex, women with BMS had higher T-scores for somatization, obsessive-compulsive, paranoid ideation, GSI, PST, and PSDI than women in the control group. In contrast, only the PSDI score was significantly higher in men with BMS compared to men in the control group. There was a significant difference in the T-scores for somatization, psychoticism, and GSI between the three age subgroups (≤50, 51-65, and ≥66 years). The obsessive-compulsive and PSDI scores were significantly higher in patients with BMS who also had at least one chronic disease than in patients with BMS who had no chronic disease. In conclusion, psychological factors are correlated with BMS.

Various approaches have been described for excision of a submandibular gland including endoscopic and robot-assisted techniques. We present the outcome of excision by a robot-assisted postauricular facelift approach and compare it with the conventional transcervical approach. We studied 30 cases of excision of the gland for benign disease (16 transcervical and 14 robot-assisted), and collected clinical and personal data, and details of patients' satisfaction with the result. The most common conditions were sialadenitis (n=15) and pleomorphic adenoma (n=12). The robot-assisted operations took significantly longer (p=0.045), had more drainage (p<0.001), and a significantly better cosmetic outcome (p=0.002). Robot-assisted excision of the submandibular gland may prove to be a viable option in the treatment of benign conditions for those patients seeking a better cosmetic outcome.

A large body of evidence has been brought forward connecting developmental immune activation to abnormal fear and anxiety levels. Anxiety disorders have extremely high lifetime prevalence, yet susceptibility factors that contribute to their emergence are poorly understood. In this research we investigated whether an inflammatory insult early in life can alter the response to fear conditioning in adulthood. Fear learning and extinction are important and adaptive behaviors, mediated largely by the amygdala and its interconnectivity with cortico-limbic circuits. Male and female rat pups were given LPS (100µg/kg i.p.) or saline at postnatal day 14; LPS activated cFos expression in the central amygdala 2.5h after exposure, but not the basal or lateral nuclei. When tested in adulthood, acquisition of an auditory cued or contextual learned fear memory was largely unaffected as was the extinction of fear to a conditioned context. However, we detected a deficit in auditory fear extinction in male and female rats that experienced early-life inflammation, such that there is a significant delay in fear extinction processes resulting in more sustained fear behaviors in response to a conditioned cue. This response was specific to extinction training and did not persist into extinction recall. The effect could not be explained by differences in pain threshold (unaltered) or in baseline anxiety, which was elevated in adolescent females only and unaltered in adolescent males and adult males and females. This research provides further evidence for the involvement of the immune system during development in the shaping of fear and anxiety related behaviors.

Early-life inflammation has been shown to exert profound effects on brain development and behavior, including altered emotional behavior, stress responsivity and neurochemical/neuropeptide receptor expression and function. The current study extends this research by examining the impact of inflammation, triggered with the bacterial compound lipopolysaccharide (LPS) on postnatal day (P) 14, on social behavior during adolescence. We investigated the role that the endocannabinoid (eCB) system plays in sociability after early-life LPS. To test this, multiple cohorts of Sprague Dawley rats were injected with LPS on P14. In adolescence, rats were subjected to behavioral testing in a reciprocal social interaction paradigm as well as the open field. We quantified eCB levels in the amygdala of P14 and adolescent animals (anandamide and 2-arachidonoylglycerol) as well as adolescent amygdaloid cannabinoid receptor 1 (CB1) binding site density and the hydrolytic activity of the enzyme fatty acid amide hydrolase (FAAH), which metabolizes the eCB anandamide. Additionally, we examined the impact of FAAH inhibition on alterations in social behavior. Our results indicate that P14 LPS decreases adolescent social behavior (play and social non-play) in males and females at P40. This behavioral alteration is accompanied by decreased CB1 binding, increased anandamide levels and increased FAAH activity. Oral administration of the FAAH inhibitor PF-04457845 (1mg/kg) prior to the social interaction task normalizes LPS-induced alterations in social behavior, while not affecting social behavior in the control group. Infusion of 10ng PF-04457845 into the basolateral amygdala normalized social behavior in LPS injected females. These data suggest that alterations in eCB signaling following postnatal inflammation contribute to impairments in social behavior during adolescence and that inhibition of FAAH could be a novel target for disorders involving social deficits such as social anxiety disorders or autism.

The aim of this study was to evaluate the technical feasibility and safety of robot-assisted modified radical neck dissection (MRND) for head and neck cancer patients with a clinically node-positive neck. The cases of 10 head and neck cancer patients who underwent unilateral therapeutic robot-assisted MRND by post-auricular facelift approach were analyzed. The robot-assisted MRND was completed successfully in all patients without any conversion to conventional neck dissection. The mean number of lymph nodes removed was 36.7±8.6. The mean duration of surgery for robot-assisted MRND was 274±65min (range 175-395min). Transient marginal nerve palsy occurred in two patients and partial necrosis of the skin flap occurred in one patient. In terms of cosmetic satisfaction, 70% of patients were very satisfied or satisfied with postoperative cosmesis. In conclusion, robot-assisted MRND by post-auricular facelift approach is technically feasible and safe in selected patients with head and neck cancer, and yields excellent postoperative cosmesis.
