Abstract
Localized synovial cell sarcomas are treated with surgical resection followed by chemo-radiation. Surgical resection of synovial sarcoma of the oropharynx and hypopharynx involves lip-splitting mandibulotomy resulting in treatment related morbidity. We report the successful use of Trans Oral Robotic Surgery for resection of localized synovial sarcoma of the lateral pharyngeal wall in a 15 year old patient. We were able to achieve negative surgical margins and avoid open surgery with its associated morbidity. At 2 years follow-up, patient is disease free, with no deficits in speech or swallowing functions and no cosmetic deformity.

Abstract
We report on an InAs quantum dot (QD) hybrid structure with a top surface QD layer coupled to two buried QD layers that is highly sensitive to surface passivation. After 180 min of passivation, the photoluminescence (PL) peak of the surface QDs shifts from 1545 to 1275 nm while its intensity decreases by one order of magnitude. Time-resolved PL reveals a significant decrease of carrier tunneling between the QD layers because of the surface state modification by chemical treatment. A simple model with rate equations is used to explain the observed optical performance. Our results show that the optical performance of this hybrid structure is very sensitive to the surface environment, making it a potential candidate for sensing applications.

Abstract
It is unclear whether the current threshold for 'high' hepatitis C virus (HCV) RNA level (800,000 IU/mL) is optimal for predicting sustained virological response (SVR). We retrospectively analysed pretreatment HCV RNA levels and SVR rates in 1529 mono-infected and 176 HIV-HCV co-infected patients treated with peginterferon alfa-2a (40 kD) plus ribavirin. We improved the threshold for differentiating low and high viral load by fitting semiparametric generalized additive logistic regression models to the data and constructing receiver operating characteristics curves. Among HCV genotype 1 mono-infected patients, the difference in SVR rates between those with low and high baseline HCV RNA levels was 27% (70%vs 43%) when 400,000 IU/mL was used and 16% (59%vs 43%) when 800,000 IU/mL was used. In HIV-HCV genotype 1 co-infected patients, the difference was 51% (71%vs 20%) when 400,000 IU/mL was used and 43% (61%vs 18%) when 800,000 IU/mL was used. A lower threshold (200,000 IU/mL) was identified for genotype 1 mono-infected patients with 'normal' alanine aminotransferase (ALT) levels. No threshold could be identified in HCV genotype 2 or 3 patients. A threshold HCV RNA level of 400,000 IU/mL is optimal for differentiating high and low probability of SVR in genotype 1-infected individuals with elevated ALT.

Abstract
A total of 12 epileptic patients (14 shoulders) with recurrent seizures and anterior dislocations of the shoulder underwent a Latarjet procedure and were reviewed at a mean of 8.3 years (1 to 20) post-operatively. Mean forward flexion decreased from 165° (100° to 180°) to 160° (90° to 180°) (p = 0.5) and mean external rotation from 54° (10° to 90°) to 43° (5° to 75°) (p = 0.058). The mean Rowe score was 76 (35 to 100) at the final follow-up. Radiologically, all shoulders showed a glenoid-rim defect and Hill-Sachs lesions pre-operatively. Osteo-arthritic changes of the glenohumeral joint were observed in five shoulders (36%) pre-operatively and in eight shoulders (57%) post-operatively. Re-dislocation during a seizure occurred in six shoulders (43%). Five of these patients underwent revision surgery using a bone buttress from the iliac crest and two of these patients re-dislocated due to a new seizure. Due to the unacceptably high rate of re-dislocation after surgery in these patients, the most important means of reducing the incidence of further dislocation is the medical management of the seizures. The Latarjet procedure should be reserved for the well-controlled patient with epilepsy who has recurrent anterior dislocation of the shoulder during activities of daily living.

Abstract
OBJECTIVE The aim of this study was to evaluate the effect of monochrome liquid crystal displays (LCDs) with different resolutions on observer performance during detection of small solitary pulmonary nodules. METHODS Chest images of digital radiography were selected online from the hospital's picture archiving and communication system. Of the 164 images selected, small solitary non-calcified pulmonary nodules were present in 63 images and absent in 101 images. Observer performance was assessed among 3 extremely experienced, 3 very experienced and 3 moderately experienced radiologists, who independently interpreted these images on 2, 3 and 5 megapixel greyscale LCDs. A five-point confidence level rating scale was used to represent the presence of nodules: definite absence, probable absence, indetermination, probable presence and definite presence. The observers were requested to rank each image on the given display according to the presence of the pulmonary nodule. Observer performance was analysed in terms of receiver operating characteristics (ROCs). RESULTS The areas under the ROC curves which represented the observer performance for the 2, 3 and 5 megapixel LCDs were found to be 0.705, 0.722 and 0.764, respectively, for the extremely experienced radiologists; 0.687, 0.712 and 0.721, respectively, for the very experienced radiologists; and 0.689, 0.696 and 0.711, respectively, for the moderately experienced radiologists. These differences were not statistically significant. CONCLUSION The observer performances for detection of small solitary non-calcified pulmonary nodules by radiologists with varying degrees of experience were comparable between the 2, 3 and 5 megapixel monochrome LCDs.

Abstract
Extinguishing abnormally strengthened learned responses to cues associated with drugs of abuse remains a key tactic for alleviating addiction. To assist in developing pharmacotherapies to augment exposure therapy for relapse prevention, investigation into neurobiological underpinnings of drug-cue extinction learning is needed. We used regional analyses of c-Fos and GluR2 protein expression to delineate neural activity and plasticity that may be associated with cocaine-cue extinction learning. Rats were trained to self-administer cocaine paired with a light cue, and later underwent a single 2h extinction session for which cocaine was withheld but response-contingent cues were presented (cocaine-cue extinction). Control groups consisted of rats yoked to animals self-administering cocaine and receiving saline non-contingently followed by an extinction session, or rats trained to self-administer cocaine followed by a no-extinction session for which levers were retracted, and cocaine and cues were withheld. Among 11 brain sites examined, extinction training increased c-Fos expression in basolateral amygdala and prelimbic prefrontal cortex of cocaine-cue extinguished rats relative to both control conditions. In dorsal subiculum and infralimbic prefrontal cortex, extinction training increased c-Fos expression in both cocaine-cue and saline-cue extinguished rats relative to the no-extinction control condition. GluR2 protein expression was not altered in any site examined after extinction or control training. Findings suggest that basolateral amygdala and prelimbic prefrontal cortex neurons are activated during acquisition of cocaine-cue extinction learning, a process that is independent of changes in GluR2 abundance. Other sites are implicated in processing the significance of cues that are present early in extinction training.

Abstract
Alteration of human leukocyte antigen (HLA) expression, such as decreased HLA I (HLA-A, -B and -C) antigens and elevated nonclassical HLA I antigens (HLA-E, -F and -G), was reported to have an unfavorable prognosis in various cancers. In our study, HLA-F expression in 105 primary esophageal squamous cell carcinoma (ESCC) lesions and 62 case-matched adjacent normal tissues, and HLA I antigens among 68 cases were analyzed by immunohistochemistry. Data revealed that HLA-F expression was observed in 58.1% (61/105) of the ESCC lesions and in 54.8% (34/62) of the normal esophageal tissues. Among the 62 case-matched samples, HLA-F expression (lesion vs. normal tissue) was upregulated, unchanged and downregulated in 13 (21.0%), 6 (9.6%) and 43 (69.4%) cases, respectively. Patients with HLA-F positive had a worse survival than those with HLA-F negative (p = 0.040). Patients with upregulated HLA-F expression (lesion vs. normal tissue) had significantly worse survival than those with HLA-F unchanged and downregulated (p = 0.010). Furthermore, decreased HLA I expression was observed in 41.2% (28/68) patients and was with worse prognosis in comparison to those with preserved HLA I expression (p = 0.001). Multivariate analysis using Cox's proportional hazards model revealed that upregulated HLA-F expression (p = 0.026) and downregulated HLA I expression (p = 0.013) could be an independent unfavorable prognostic factor. In conclusion, our study provided the evidence that alteration of HLA I and HLA-F antigen expression was associated with survival in patients with ESCC.
