Meningoencephalitis Following Endoscopic Dacryocystorhinostomy
An 81-year-old man with unilateral nasolacrimal duct obstruction underwent routine endonasal dacryocystorhinostomy and 2 days postoperatively developed a severe headache and rigors. Subsequent CT and MRI imaging demonstrated a defect in the floor of the right anterior cranial fossa, which possibly was damaged during the operation, and meningoencephalitis of the adjacent frontal lobe gyrus. Following intravenous antibiotic treatment, the patient made a full recovery with no ongoing sequelae, and his epiphora completely resolved. To the authors' knowledge, this is the first report of meningoencephalitis following endonasal dacryocystorhinostomy. This complication should be considered in any patient with a febrile septic presentation or headache following endonasal dacryocystorhinostomy. Accepted for publication December 30, 2018.

Etiopathogenesis of Primary Acquired Nasolacrimal Duct Obstruction: What We Know and What We Need to Know
Purpose: To provide a systematic review of the literature on the etiopathogenesis of primary acquired nasolacrimal duct obstruction (PANDO). Methods: The authors performed a PubMed search of all articles published in English with specific reference to etiopathogenesis of PANDO or associations of PANDO. Data captured include demographics, study techniques, hypothesis, presumed or confirmed interpretations with regards to pathogenesis, mechanisms, or pathways. Specific emphasis was laid on addressing the lacunae and potential directions for future research. Results: Numerous factors are believed to contribute to the etiopathogenesis of PANDO. The basic pathogenesis involves inflammation, vascular congestion, mucosal edema, fibrosis, obstruction, and stasis. Bony nasolacrimal duct diameter does not appear to play a significant role. There is no convincing data to substantiate nose as the site of disease origin and nasal factors appear to be comorbidities. Hormonal mechanisms are more evidence-based but can only partly explain the pathogenesis. Vascular theories are based on the behavior of perilacrimal cavernous bodies, their autonomic control, and additional structural changes in the helical patterns of connective tissue fiber arrangements. Repeated vascular malfunction leading to structural epithelial and subepithelial changes currently appears to be the most evidence-based and accepted theory. Tear proteomics holds a promise in decoding the etiopathogenesis of PANDO, at least in part. Conclusions: The etiopathogenesis of PANDO appears to be multifactorial. Hormonal microenvironments, vascular factors, and tear proteomics are promising candidates for further work. There is a need for focused work by Clinician-Scientists and the answers can have far reaching clinical implications. Accepted for publication December 12, 2018.

A Multivariable Model Predictive of Unplanned Postoperative Intubation in Infant Surgical Patients
BACKGROUND: Unplanned postoperative intubation is an important quality indicator, and is associated with significantly increased mortality in children. Infant patients are more likely than older pediatric patients to experience unplanned postoperative intubation, yet the literature provides few characterizations of this outcome in our youngest patients. The objective of this study was to identify risk factors for unplanned postoperative intubation and to develop a scoring system to predict this complication in infants undergoing major surgical procedures. METHODS: In this retrospective cohort study, The National Surgical Quality Improvement Program-Pediatric database was surveyed for all infants who underwent noncardiac surgery between January 1, 2012 and December 31, 2015 (derivation cohort, n = 56,962) and between January 1 and December 31, 2016 (validation cohort, n = 20,559). Demographic and perioperative clinical characteristics were examined in association with our primary outcome of unplanned postoperative intubation within 30 days of surgery. Risk factors were analyzed in the derivation cohort (2012–2015 data) using multivariable logistic regression with stepwise selection. Parameters from the final model were used to create a scoring system for predicting unplanned postoperative intubation. Data from the validation cohort were utilized to assess the performance of the scoring system using the area under the receiver operating characteristic curve. RESULTS: In the derivation cohort, 2.2% of the infants experienced unplanned postoperative intubation within 30 days of surgery. Of the 14 risk factors identified in multivariable analysis, 10 (age, prematurity, American Society of Anesthesiologists physical status, inpatient status, operative time >120 minutes, cardiac disease, malignancy, hematologic disorder, oxygen supplementation, and nutritional support) were included in the final multivariable logistic regression model to create the risk score. The area under the receiver operating characteristic curve of the final model was 0.86 (95% CI, 0.85–0.87) for the derivation cohort and 0.83 (95% CI, 0.82–0.85) for the validation cohort. CONCLUSIONS: About 1 in 50 infants undergoing major surgical procedures experiences unplanned postoperative intubation. Our scoring system based on routinely collected perioperative assessment data can predict risk in infants with good accuracy. Further investigation should assess the clinical utility of the scoring system for risk stratification and improvement in perioperative care quality and patient outcomes.

Effectiveness of Magnesium in Preventing Shivering in Surgical Patients: A Systematic Review and Meta-analysis
BACKGROUND: Clinical trials regarding the antishivering effect of perioperative magnesium have produced inconsistent results. We conducted a systematic review and meta-analysis with Trial Sequential Analysis to evaluate the effect of perioperative magnesium on prevention of shivering. METHODS: We searched PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, and 2 registry sites for randomized clinical trials that compared the administration of magnesium to a placebo or no treatment in patients undergoing surgeries. The primary outcome of this meta-analysis was the incidence of shivering. The incidence of shivering was combined as a risk ratio with 95% CI using a random-effect model. The effect of the route of administration was evaluated in a subgroup analysis, and Trial Sequential Analysis with a risk of type 1 error of 5% and power of 90% was performed. The quality of each included trial was evaluated, and the quality of evidence was assessed using the Grading of Recommendation Assessment, Development, and Evaluation approach. We also assessed adverse events. RESULTS: Sixty-four trials and 4303 patients (2300 and 2003 patients in magnesium and control groups, respectively) were included. The overall incidence of shivering was 9.9% in the magnesium group and 23.0% in the control group (risk ratio, 0.42; 95% CI, 0.33–0.52). Subgroup analysis revealed that the incidence of shivering was lower with IV (risk ratio, 0.29; 95% CI, 0.29–0.54; Grading of Recommendation Assessment, Development, and Evaluation, moderate), epidural (risk ratio, 0.24; 95% CI, 0.13–0.43; Grading of Recommendation Assessment, Development, and Evaluation, low), and intrathecal administration (risk ratio, 0.64; 95% CI, 0.43–0.96; Grading of Recommendation Assessment, Development, and Evaluation, moderate). Only trials with low risk of bias were included for Trial Sequential Analysis. The Z-cumulative curve for IV magnesium crossed the Trial Sequential Analysis monitoring boundary for benefit even though only 34.9% of the target sample size had been reached. The Z-cumulative curve for epidural or intrathecal administration did not cross the Trial Sequential Analysis monitoring boundary for benefit. No increase in adverse events was reported. CONCLUSIONS: Perioperative IV administration of magnesium effectively reduced shivering and Trial Sequential Analysis suggested that no more trials are required to confirm that IV magnesium effectively reduces shivering.

Editorial by US Food and Drug Administration Attorney Fails to Address Core and Ongoing Issues Seen With Vasopressin Market
Perioperative Care for Adolescents Undergoing Major Surgery: A Biopsychosocial Conceptual Framework
American Society for Enhanced Recovery and Perioperative Quality Initiative-4 Joint Consensus Statement on Persistent Postoperative Opioid Use: Definition, Incidence, Risk Factors, and Health Care System Initiatives
Persistent postoperative opioid use is thought to contribute to the ongoing opioid epidemic in the United States. However, efforts to study and address the issue have been stymied by the lack of a standard definition, which has also hampered efforts to measure the incidence of and risk factors for persistent postoperative opioid use. The objective of this systematic review is to (1) determine a clinically relevant definition of persistent postoperative opioid use, and (2) characterize its incidence and risk factors for several common surgeries. Our approach leveraged a group of international experts from the Perioperative Quality Initiative-4, a consensus-building conference that included representation from anesthesiology, surgery, and nursing. A search of the medical literature yielded 46 articles addressing persistent postoperative opioid use in adults after arthroplasty, abdominopelvic surgery, spine surgery, thoracic surgery, mastectomy, and thoracic surgery. In opioid-naive patients, the overall incidence ranged from 2% to 6% based on moderate-level evidence. However, patients who use opioids preoperatively had an incidence of >30%. Preoperative opioid use, depression, factors associated with the diagnosis of substance use disorder, preoperative pain, and tobacco use were reported risk factors. In addition, while anxiety, sex, and psychotropic prescription are associated with persistent postoperative opioid use, these reports are based on lower level evidence. While few articles addressed the health policy or prescriber characteristics that influence persistent postoperative opioid use, efforts to modify prescriber behaviors and health system characteristics are likely to have success in reducing persistent postoperative opioid use.

I Tweet, Therefore I Learn: An Analysis of Twitter Use Across Anesthesiology Conferences
BACKGROUND: Twitter in anesthesiology conferences promotes rapid science dissemination, global audience participation, and real-time updates of simultaneous sessions. We designed this study to determine if an association exists between conference attendance/registration and 4 defined Twitter metrics. METHODS: Using publicly available data through the Symplur Healthcare Hashtags Project and the Symplur Signals, we collected data on total tweets, impressions, retweets, and replies as 4 primary outcome metrics for all registered anesthesiology conferences occurring from May 1, 2016 to April 30, 2017. The number of Twitter participants, defined as users who contributed a tweet, retweet, or reply 3 days before through 3 days after the conference, was collected. We also collected influencer data as determined by mentions (number of times a user is referenced). Two authors independently verified the categories for influencers assigned by Symplur. Conference demographic data were obtained by e-mail inquiries. Associations between meeting attendees/registrants and Twitter metrics, between Twitter participants and the metrics, and between physician influencers and Twitter participants were tested using Spearman rho. RESULTS: Fourteen conferences with 63,180 tweets were included. With the American Society of Anesthesiologists annual meeting included, the correlations between meeting attendance/registration and total tweets (rs = 0.588; P = .074), impressions (rs = 0.527; P = .117), and retweets (rs = 0.539; P = .108) were not statistically significant; for replies, it was moderately positive (rs = 0.648; P = .043). Without the American Society of Anesthesiologists annual meeting, total tweets (rs = 0.433; P = .244), impressions (rs = 0.350; P = .356), retweets (rs = 0.367; P = .332), and replies (rs = 0.517; P = .154) were not statistically significant. Secondary outcomes include a highly positive correlation between Twitter participation and total tweets (rs = 0.855; P

Prevalence and Multivariable Factors Associated With Preoperative Cognitive Impairment in Outpatient Surgery in the United States
Preoperative cognitive impairment increases the risk of adverse events after surgery but its prevalence in outpatient surgery has not been defined. We aimed to determine the prevalence and multivariable factors associated with cognitive impairment in individuals who present for outpatient surgery. We used data from the Health and Retirement Study, a longitudinal panel survey of older Americans. Of 1836 participants who reported having outpatient surgery, we found that 16.1% had evidence of cognitive impairment. Significant multivariable factors associated with preoperative cognitive impairment included non-Hispanic African American race, prior stroke, preoperative functional dependence, and lower socioeconomic status and education level.

Contemplating Our Maternity Care Crisis in the United States: Reflections of an Obstetrician Anesthesiologist
High-Flow Nasal Oxygen Improves Safe Apnea Time in Morbidly Obese Patients Undergoing General Anesthesia: A Randomized Controlled Trial
BACKGROUND: Morbidly obese patients undergoing general anesthesia are at risk of hypoxemia during anesthesia induction. High-flow nasal oxygenation use during anesthesia induction prolongs safe apnea time in nonobese surgical patients. The primary objective of our study was to compare safe apnea time, between patients given high-flow nasal oxygenation or conventional facemask oxygenation during anesthesia induction, in morbidly obese surgical patients. METHODS: Research ethics board approval was obtained. Elective surgical patients ≥18 years with body mass index ≥40 kg·m−2 were included. Patients with severe comorbidity, gastric reflux disease, known difficult airway, or nasal obstruction were excluded. After obtaining informed consent patients were randomized. In the intervention (high-flow nasal oxygenation) group, preoxygenation was provided by 100% nasal oxygen for 3 minutes at 40 L·minute−1; in the control group, preoxygenation was delivered using a facemask with 100% oxygen, targeting end-tidal O2 >85%. Anesthesia was induced with propofol, remifentanil, and rocuronium. Bag-mask ventilation was not performed. At 2 minutes after rocuronium, videolaryngoscopy was performed. If the laryngoscopy grade was I or II, laryngoscope was left in place and the study was continued; if grade III or IV was observed, the patient was excluded from the study. During the apnea period, high-flow nasal oxygenation patients received nasal oxygen at 60 L·minute−1; control group patients received no supplemental oxygen. The primary outcome, safe apnea time, was reached when oxygen saturation measured by pulse oximetry (SpO2) fell to 95% or maximum 6 minutes of apnea. The patient was then intubated. T tests and χ2 analyses were used to compare groups. P

Effect of Topical Periocular Steroid Use on Intraocular Pressure: A Retrospective Analysis
Purpose: To study the effect of periocular steroid use on intraocular pressure (IOP). Methods: Charts of adult patients with atopic dermatitis or eczema treated with topical periocular steroid creams and ointments from January 1st, 2007 to October 1st, 2017 were reviewed. Patients with the following were excluded: glaucoma, ocular hypertension, known systemic/topical/injectable steroid history, and lack of documented IOP prior to or during treatment with periocular steroid ointment. Patient data were collected regarding gender, treatment regimen, as well as IOP prior to and during treatment. Steroid responders were identified. Statistical analysis was performed using linear mixed effects models adjusting for follow-up time to test the relationship between pre and posttreatment IOP change adjusting for intereye correlations. Results: Thirty-one patients were identified. Twenty-one were treated bilaterally and 10 unilaterally. Five patients were glaucoma suspects. The mean treatment period was 14.2 weeks with a range of 0.1–83.9 weeks. Patients were treated with fluorometholone (42%), loteprednol etabonate (23%), dexamethasone-neomycin-polymyxin B (13%), hydrocortisone 1% or 2.5% (3%), and tobramycin-dexamethasone (19%). In the combined sample, there was no significant IOP change even after adjusting for follow-up time (mean change: +0.44 mm Hg, p = 0.126). However, eyes with baseline IOP ≥ 14 mm Hg had a significant increase (+0.73 mm Hg/year, p = 0.032). Individual steroid responses included the following: 1 intermediate and 30 low responders, of which 19 patients had an IOP change of

Giant Dermatofibrosarcoma Protuberans With Bilateral Orbital Involvement
Dermatofibroma sarcoma protuberans (DFSP) is a rare, locally aggressive soft tissue sarcoma with a tendency for recurrence after excision. Although reports of unilateral orbital and bilateral eyelid disease exist, there have been no prior reports of DFSP with bilateral orbital involvement and no previously described cases of DFSP associated with transient optic neuropathy. The authors present a case report of a 34-year-old woman with a giant scalp DFSP involving the bilateral orbits. Despite radical resection with 5 cm margins where possible, multiple positive margins remained including deep positive margins at the bilateral superomedial retroseptal soft tissue. The patient completed adjuvant radiation for surgically unresectable disease. This case highlights the challenge of achieving local control given the disease extent and infiltration of the bilateral eyelids and orbits. This is the first reported case of DFSP with bilateral orbital involvement and associated transient optic neuropathy. Accepted for publication November 29, 2018.

Posttraumatic Emphysema of the Optic Nerve Sheath
The authors describe the case of a 19-year-old female who suffered posttraumatic emphysema of the optic nerve sheath. She suffered massive head trauma requiring emergent neurosurgery and was incidentally found to have air in her optic nerve sheath on CT scan. At 6 weeks follow up, her visual acuity (20/25 uncorrected) and color perception in the affected eye were excellent. Her examination was notable for an afferent pupillary defect, mild disc pallor, and optic nerve atrophy on optical coherence tomography. This is a case of a patient with posttraumatic optic nerve sheath emphysema who recovered excellent visual function and received follow-up ophthalmic imaging.

Subgroup analysis revealed that the incidence of shivering was lower with IV (risk ratio, 0.29; 95% CI, 0.29–0.54; Grading of Recommendation Assessment, Development, and Evaluation, moderate), epidural (risk ratio, 0.24; 95% CI, 0.13–0.43; Grading of Recommendation Assessment, Development, and Evaluation, low), and intrathecal administration (risk ratio, 0.64; 95% CI, 0.43–0.96; Grading of Recommendation Assessment, Development, and Evaluation, moderate). Only trials with low risk of bias were included for Trial Sequential Analysis. The Z-cumulative curve for IV magnesium crossed the Trial Sequential Analysis monitoring boundary for benefit even though only 34.9% of the target sample size had been reached. The Z-cumulative curve for epidural or intrathecal administration did not cross the Trial Sequential Analysis monitoring boundary for benefit. No increase in adverse events was reported. CONCLUSIONS: Perioperative IV administration of magnesium effectively reduced shivering and Trial Sequential Analysis suggested that no more trials are required to confirm that IV magnesium effectively reduces shivering.

Editorial by US Food and Drug Administration Attorney Fails to Address Core and Ongoing Issues Seen With Vasopressin Market
Perioperative Care for Adolescents Undergoing Major Surgery: A Biopsychosocial Conceptual Framework
American Society for Enhanced Recovery and Perioperative Quality Initiative-4 Joint Consensus Statement on Persistent Postoperative Opioid Use: Definition, Incidence, Risk Factors, and Health Care System Initiatives
Persistent postoperative opioid use is thought to contribute to the ongoing opioid epidemic in the United States. However, efforts to study and address the issue have been stymied by the lack of a standard definition, which has also hampered efforts to measure the incidence of and risk factors for persistent postoperative opioid use. The objective of this systematic review is to (1) determine a clinically relevant definition of persistent postoperative opioid use, and (2) characterize its incidence and risk factors for several common surgeries. Our approach leveraged a group of international experts from the Perioperative Quality Initiative-4, a consensus-building conference that included representation from anesthesiology, surgery, and nursing. A search of the medical literature yielded 46 articles addressing persistent postoperative opioid use in adults after arthroplasty, abdominopelvic surgery, spine surgery, thoracic surgery, mastectomy, and thoracic surgery. In opioid-naive patients, the overall incidence ranged from 2% to 6% based on moderate-level evidence. However, patients who use opioids preoperatively had an incidence of >30%. Preoperative opioid use, depression, factors associated with the diagnosis of substance use disorder, preoperative pain, and tobacco use were reported risk factors. In addition, while anxiety, sex, and psychotropic prescription are associated with persistent postoperative opioid use, these reports are based on lower level evidence. While few articles addressed the health policy or prescriber characteristics that influence persistent postoperative opioid use, efforts to modify prescriber behaviors and health system characteristics are likely to have success in reducing persistent postoperative opioid use.

I Tweet, Therefore I Learn: An Analysis of Twitter Use Across Anesthesiology Conferences
BACKGROUND: Twitter in anesthesiology conferences promotes rapid science dissemination, global audience participation, and real-time updates of simultaneous sessions. We designed this study to determine if an association exists between conference attendance/registration and 4 defined Twitter metrics. METHODS: Using publicly available data through the Symplur Healthcare Hashtags Project and the Symplur Signals, we collected data on total tweets, impressions, retweets, and replies as 4 primary outcome metrics for all registered anesthesiology conferences occurring from May 1, 2016 to April 30, 2017. The number of Twitter participants, defined as users who contributed a tweet, retweet, or reply 3 days before through 3 days after the conference, was collected. We also collected influencer data as determined by mentions (number of times a user is referenced). Two authors independently verified the categories for influencers assigned by Symplur. Conference demographic data were obtained by e-mail inquiries. Associations between meeting attendees/registrants and Twitter metrics, between Twitter participants and the metrics, and between physician influencers and Twitter participants were tested using Spearman rho. RESULTS: Fourteen conferences with 63,180 tweets were included. With the American Society of Anesthesiologists annual meeting included, the correlations between meeting attendance/registration and total tweets (rs = 0.588; P = .074), impressions (rs = 0.527; P = .117), and retweets (rs = 0.539; P = .108) were not statistically significant; for replies, it was moderately positive (rs = 0.648; P = .043). Without the American Society of Anesthesiologists annual meeting, total tweets (rs = 0.433; P = .244), impressions (rs = 0.350; P = .356), retweets (rs = 0.367; P = .332), and replies (rs = 0.517; P = .154) were not statistically significant. Secondary outcomes include a highly positive correlation between Twitter participation and total tweets (rs = 0.855; P

Prevalence and Multivariable Factors Associated With Preoperative Cognitive Impairment in Outpatient Surgery in the United States
Preoperative cognitive impairment increases the risk of adverse events after surgery but its prevalence in outpatient surgery has not been defined. We aimed to determine the prevalence and multivariable factors associated with cognitive impairment in individuals who present for outpatient surgery. We used data from the Health and Retirement Study, a longitudinal panel survey of older Americans. Of 1836 participants who reported having outpatient surgery, we found that 16.1% had evidence of cognitive impairment. Significant multivariable factors associated with preoperative cognitive impairment included non-Hispanic African American race, prior stroke, preoperative functional dependence, and lower socioeconomic status and education level.

Contemplating Our Maternity Care Crisis in the United States: Reflections of an Obstetrician Anesthesiologist
High-Flow Nasal Oxygen Improves Safe Apnea Time in Morbidly Obese Patients Undergoing General Anesthesia: A Randomized Controlled Trial
BACKGROUND: Morbidly obese patients undergoing general anesthesia are at risk of hypoxemia during anesthesia induction. High-flow nasal oxygenation use during anesthesia induction prolongs safe apnea time in nonobese surgical patients. The primary objective of our study was to compare safe apnea time, between patients given high-flow nasal oxygenation or conventional facemask oxygenation during anesthesia induction, in morbidly obese surgical patients. METHODS: Research ethics board approval was obtained. Elective surgical patients ≥18 years with body mass index ≥40 kg·m−2 were included. Patients with severe comorbidity, gastric reflux disease, known difficult airway, or nasal obstruction were excluded. After obtaining informed consent patients were randomized. In the intervention (high-flow nasal oxygenation) group, preoxygenation was provided by 100% nasal oxygen for 3 minutes at 40 L·minute−1; in the control group, preoxygenation was delivered using a facemask with 100% oxygen, targeting end-tidal O2 >85%. Anesthesia was induced with propofol, remifentanil, and rocuronium. Bag-mask ventilation was not performed. At 2 minutes after rocuronium, videolaryngoscopy was performed. If the laryngoscopy grade was I or II, laryngoscope was left in place and the study was continued; if grade III or IV was observed, the patient was excluded from the study. During the apnea period, high-flow nasal oxygenation patients received nasal oxygen at 60 L·minute−1; control group patients received no supplemental oxygen. The primary outcome, safe apnea time, was reached when oxygen saturation measured by pulse oximetry (SpO2) fell to 95% or maximum 6 minutes of apnea. The patient was then intubated. T tests and χ2 analyses were used to compare groups. P

Questions About the Study by Said Et Al
Parent-Child Interaction Therapy for Children with Developmental Delay: The Role of Sleep Problems
ABSTRACT: Objective: Sleep problems are common and associated with externalizing behavior problems in young children, particularly among young children with developmental delay (DD). The aims of the current study, which was a secondary data analysis of 2 previously conducted randomized controlled trials, were to assess whether parent-child interaction therapy (PCIT) led to decreases in child sleep problems and whether initial sleep problems moderated the effect of PCIT on child behavior. Methods: The study participants were 44 children (M = 49.19 months, SD = 13.1) with DD or borderline DD and with co-occurring clinically significant levels of externalizing behavior problems and their mothers (M = 35.9 years, SD = 7.3). These participants were randomly assigned to either an immediate treatment group or a waitlist control group. Results: Findings revealed a significant direct effect of PCIT on decreases in sleep problems. Additionally, moderation analyses revealed that lower levels of child sleep problems at pretreatment were associated with greater improvements in observed child compliance compared with higher levels of child sleep problems at pretreatment. Conclusion: This study extends previous findings by providing support for the preliminary efficacy of PCIT in reducing sleep problems in children with DD and borderline DD and highlighting the role of sleep problems as a factor associated with differential treatment effects in behavioral parenting intervention research.

Synchronous multifocal necrotizing soft tissue infections: a case report and literature review
Abstract
Necrotizing soft tissue infections are a group of conditions with a common pathophysiological basis, affecting any or all layers of the soft tissue compartment. They are rare, life-threatening diseases that require a high index of suspicion for early detection as well as urgent surgical debridement. Rarely, they can occur in more than one non-contiguous site of the body ('multifocal' disease), and this is associated with a much higher mortality than monofocal disease. Here, we present the case of a 46-year-old male with bilateral upper limb necrotizing soft tissue infection following an unclear history of trauma. The patient developed septic shock necessitating transfer to the intensive care unit following emergency surgery. Microbiological tests yielded Streptococcus pyogenes, Staphylococcus aureus and opportunistic Candida spp. and Actinomyces infections. A total of seven surgical debridements were performed; fortunately, the patient survived. We discuss the presentation, diagnosis and management of this case including primary reconstruction of the soft tissue defects, and review the literature on necrotizing soft tissue infections as a clinical entity, incorporating clinical updates from the latest guidelines worldwide.
Level of Evidence: Level V, therapeutic study.

Pacentine, Teresa Nicolson Mutations in transmembrane inner ear (TMIE) cause deafness in humans; previous studies suggest involvement in the mechano-electrical transduction (MET) complex in sensory hair cells, but TMIE 's precise role is unclear. Intmie zebrafish mutants, we observed that GFP-tagged Tmc1 and Tmc2b, which are subunits of the MET channel, fail to target to the hair bundle. In contrast, overexpression of Tmie strongly enhances the targeting of Tmc1-GFP and Tmc2b-GFP to stereocilia. To identify the motifs of Tmie underlying the regulation of the Tmcs, we systematically deleted or replaced peptide segments.

Sharp Foreign Bodies of the Aero-Digestive Tract: Endoscopic Removal by the ‘Kangaroo’ Technique
Abstract
Removal of sharp foreign bodies in the aero-digestive tract may inflict iatrogenic damage to the esophagus, trachea or other vital structures in case of impalement. We describe the 'Kangaroo' technique for safe and effective removal of sharp objects from the upper aero-digestive tracts. Index Case 1: 1-year old boy presented to us with an open (un)safety-pin lodged in the upper esophagus. The technique of removal of the pin by the Kangaroo technique, along-with the mechanics of en-pouching the (un)safety-pin has been described. Index Case 2: 8 years old boy presented with accidental aspiration of a razor blade. The removal of the blade from his trachea was executed by the Kangaroo technique. The Kangaroo technique is described for safe endoscopic extraction of sharp foreign body from the aero-digestive tract while protecting the surrounding tissues, to maintain control of the object during extraction and to avoid causing iatrogenic damage by enclosing the foreign body in a 'kangaroo pouch'. The advantages and limitations of the technique have been discussed. The Kangaroo technique is safe, effective and reproducible way to effect removal of sharp object from the aerodigestive tract while preventing iatrogenic injury to the surrounding organs.

Pre-operative assessment of 30-day mortality risk after major surgery: the role of the quick sequential organ failure assessment: A retrospective observational study
BACKGROUND The quick Sequential Organ Failure Assessment (qSOFA) is intended for the assessment of the prognosis and risk of sepsis. It may also help predict the mortality risk of nonseptic patients. OBJECTIVE This study investigated the relationship between pre-operative qSOFA scores and 30-day mortality after major surgery. It also evaluated the predictive value of qSOFA scores combined with the American Society of Anesthesiologists (ASA) physical status and Charlson comorbidity index (CCI). DESIGN A retrospective observational study. SETTING Single tertiary academic hospital. PATIENTS Medical records of patients who underwent major surgery (estimated blood loss >500 ml; surgery time >2 h) between January 2010 and December 2017 were examined. MAIN OUTCOME MEASURES The qSOFA score was measured within 24 h before surgery, and its association with 30-day mortality was analysed using multivariable logistic regression. A receiver-operating characteristic curve analysis was used to investigate the predictive power of the pre-operative qSOFA scores combined with the ASA physical status and with CCI. RESULTS A total of 6336 patients were included in the final analysis, and 91 (1.4%) died within 30 days. The multivariable logistic regression analysis including all covariates indicated that 30-day mortality was 2.43-times higher for the score 1 group than for the score 0 group (P = 0.002), and it was 3.54-times higher for the score at least 2 group than for the score 0 group (P

A Review of the Contribution of Mast Cells in Wound Healing: Involved Molecular and Cellular Mechanisms
Abstract
Mast cells (MCs), apart from their classic role in allergy, contribute to a number of biologic processes including wound healing. In particular, two aspects of their histologic distribution within the skin have attracted the attention of researchers to study their wound healing role; they represent up to 8% of the total number of cells within the dermis and their cutaneous versions are localized adjacent to the epidermis and the subdermal vasculature and nerves. At the onset of a cutaneous injury, the accumulation of MCs and release of proinflammatory and immunomodulatory mediators have been well documented. The role of MC-derived mediators has been investigated through the stages of wound healing including inflammation, proliferation, and remodeling. They contribute to hemostasis and clot formation by enhancing the expression of factor XIIIa in dermal dendrocytes through release of TNF-α, and contribute to clot stabilization. Keratinocytes, by secreting stem cell factor (SCF), recruit MCs to the site. MCs in return release inflammatory mediators, including predominantly histamine, VEGF, interleukin (IL)-6, and IL-8, that contribute to increase of endothelial permeability and vasodilation, and facilitate migration of inflammatory cells, mainly monocytes and neutrophils to the site of injury. MCs are capable of activating the fibroblasts and keratinocytes, the predominant cells involved in wound healing. MCs stimulate fibroblast proliferation during the proliferative phase via IL-4, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) to produce a new extracellular matrix (ECM). MC-derived mediators including fibroblast growth factor-2, VEGF, platelet-derived growth factor (PDGF), TGF-β, nerve growth factor (NGF), IL-4, and IL-8 contribute to neoangiogenesis, fibrinogenesis, or reepithelialization during the repair process. MC activation inhibition and targeting the MC-derived mediators are potential therapeutic strategies to improve wound healing through reduced inflammatory responses and scar formation.

A Review of the Contribution of Mast Cells in Wound Healing: Involved Molecular and Cellular Mechanisms
Abstract
Mast cells (MCs), apart from their classic role in allergy, contribute to a number of biologic processes including wound healing. In particular, two aspects of their histologic distribution within the skin have attracted the attention of researchers to study their wound healing role; they represent up to 8% of the total number of cells within the dermis and their cutaneous versions are localized adjacent to the epidermis and the subdermal vasculature and nerves. At the onset of a cutaneous injury, the accumulation of MCs and release of proinflammatory and immunomodulatory mediators have been well documented. The role of MC-derived mediators has been investigated through the stages of wound healing including inflammation, proliferation, and remodeling. They contribute to hemostasis and clot formation by enhancing the expression of factor XIIIa in dermal dendrocytes through release of TNF-α, and contribute to clot stabilization. Keratinocytes, by secreting stem cell factor (SCF), recruit MCs to the site. MCs in return release inflammatory mediators, including predominantly histamine, VEGF, interleukin (IL)-6, and IL-8, that contribute to increase of endothelial permeability and vasodilation, and facilitate migration of inflammatory cells, mainly monocytes and neutrophils to the site of injury. MCs are capable of activating the fibroblasts and keratinocytes, the predominant cells involved in wound healing. MCs stimulate fibroblast proliferation during the proliferative phase via IL-4, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) to produce a new extracellular matrix (ECM). MC-derived mediators including fibroblast growth factor-2, VEGF, platelet-derived growth factor (PDGF), TGF-β, nerve growth factor (NGF), IL-4, and IL-8 contribute to neoangiogenesis, fibrinogenesis, or reepithelialization during the repair process. MC activation inhibition and targeting the MC-derived mediators are potential therapeutic strategies to improve wound healing through reduced inflammatory responses and scar formation.

A Multimetric Evaluation of Online Spanish Health Resources for Lymphedema
Background Breast cancer is a leading cause of death in US Hispanic females. This demographic is more likely to present with later-stage disease and require more extensive surgical treatment, including axillary lymph node dissection, which increases risk of lymphedema. The Spanish-speaking Hispanic population has a lower health literacy level and requires materials contoured to their unique needs. The aim of this study was to evaluate online Spanish lymphedema resources. Methods A web search using the Spanish term "linfedema" was performed, and the top 10 websites were identified. Each was analyzed using validated metrics to assess readability, understandability, actionability, and cultural sensitivity using the SOL (Simplified Measure of Gobbledygook, Spanish), Patient Education and Materials Assessment for Understandability and Actionability (Patient Education and Assessment Tool), and Cultural Sensitivity and Assessment Tool (CSAT), respectively. Online materials were assessed by 2 independent evaluators, and interrater reliability was determined. Results Online lymphedema material in Spanish had a mean reading grade level of 9.8 (SOL). Average understandability and actionability scores were low at 52% and 36%, respectively. The mean CSAT was 2.27, below the recommended value of 2.5. Cohen κ for interrater reliability was greater than 0.81 for the Patient Education and Assessment Tool and CSAT, suggesting excellent agreement between raters. Conclusions Available online Spanish lymphedema resources are written at an elevated reading level and are inappropriate for a population with lower health literacy levels. As patients continue to use the internet as their primary source for health information, health care entities must improve the quality of provided Spanish resources in order to optimize patient comprehension.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2TyoMry
Repair of Sacral and Ischial Region Defects With Lateral Sacral Artery Perforator Flaps
Background Reconstructive choices for the defects of the sacral and ischial regions include various steps of the reconstructive ladder from primary closure to free flaps. This study aimed to present repair of sacral and ischial region defects with lateral sacral artery perforator (LSAP) flaps. Methods We enrolled a total of 18 patients with sacral and ischial region defects reconstructed with LSAP flaps in the study between September 2014 and October 2015. The patients were evaluated in terms of age, sex, neurological situation, etiology, defect size, defect region, flap size, perforator number, and postoperative complications. Results No patient had hematoma, seroma, and complications of the donor area. In the postoperative period, 2 patients were observed to have short-term complications (11.1%) including a partial flap loss (5.5%) due to distal venous failure (flap survival rate, 95%) and a wound site infection (5.5%). Duration of follow-up of the patients ranged between 26 and 38 months. Recurrence was observed from long-term complications of 4 patients' pressure sores (22%). Conclusions The LSAP flap has not been frequently described in the literature. We believe that LSAP flap is a flap of choice that should be considered preferably for sacral and ischial defects, which can be reliably elevated over pedicles and has short surgery duration and low surgical morbidity.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2BquF2W
Nonshaven Follicular Unit Extraction: Personal Experience
Nonshaven follicular unit extraction (NS-FUE) is the most state-of-the-art surgical technique in the field of follicular unit hair transplantation. It is particularly appealing because donor area shaving, one of the most serious impediments for the patient, can be omitted. In this article, we present our surgical approach for NS-FUE. We selectively used the direct or the pretrimming method of NS-FUE according to indication, determined by considering the location and purpose of transplantation, the condition of the recipient site, and the patient's preference. A total of 658 patients underwent NS-FUE. Of these, 17 had pubic atrichia, 2 had pubic atrichia and also received hairline correction surgery, 6 received eyebrow transplantation, 19 had female pattern hair loss, 362 had male pattern baldness (MPB), 2 had MPB and also required eyebrow transplantation, 3 received hair transplantation for MPB and scalp scar, 9 underwent male hairline correction surgery, 192 underwent female hairline surgery, and 46 received hair transplantation for scalp scar. The average numbers of transplanted grafts were 573 for atrichia, 1300 for atrichia and hairline correction performed successively, 240 for eyebrow transplantation, 996 for female pattern hair loss, 1408 for MPB (with a maximum of 3000), 1050 for MPB and eyebrow transplantation, 998 for female pattern hair loss (with a maximum of 1910), and 141 for scalp scar. On average, the total transection rate was 8.2%, and the calculated density was 2.2.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2TCuiJG
Lower Percentage of the Patients in Breast Reconstruction After Mastectomy Group Who Received Adjuvant Radiotherapy Might Be Associated With Higher Work Ability and Productivity
Quick Calculation of Breast Resection Mass Using the Schnur Scale
In 1991, Dr Paul Schnur and his colleagues published an article correlating the weight of breast tissue to be removed in a breast reduction operation with the total body surface area (BSA) of the patient. They presented a very cogent argument for selecting three groups of patients: those with medical indications for operation, those who merit review, and those whose operation could be considered cosmetic. The Schnur Sliding Scale is widely used by insurance companies in the western United States in the process of preauthorizing breast reduction operations, and its use may be spreading eastward. The Schnur group presented a nomogram for calculating BSA and a scale in the form of a table for guiding a determination of whether the patient is a reconstructive patient as opposed to an aesthetic patient. We have combined the scale and the BSA nomogram for a simplified nomogram calculator that facilitates rapid determination of anticipated tissue weight of resection for a patient of a given size. This calculator yields the required weight of tissue to remove with just knowledge of the patient's height and weight and the use of a straight edge. We demonstrate and compare performance of this calculation by hand and by nomogram. There is ample evidence that the practice of applying the Schnur Sliding Scale may be prohibitive to symptomatic patients seeking reduction mammaplasty and should be abandoned. While this practice continues, our simplified Schnur Sliding Scale nomogram is meant to help easily determine the insurer-required minimum breast resection weight and thereby both improve patient counseling prior to planning surgery and assist the surgeon with achieving insurer reimbursement for the procedure while avoiding rejected claims.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2Bn6TFk
Ensuring Sustainability for UK Burns Services: Workforce Planning for Burns Consultants
Introduction Workforce planning is an essential component of organizing any health service. Centralization of burns services pools expertise, although trainees can struggle to achieve adequate exposure to burns training. We aim to review current staffing levels and predict the future consultant numbers required for UK services to remain staffed with appropriately trained surgeons. Methods We have compiled a database of all UK burns consultants. Basic demographic data, such as age and sex, were collated. Projected UK population data have been used to estimate whether the number of patients under the care of the UK burns network will change in the coming years. Access to burns fellowship training has also been factored in. Results There are 34 burns facilities in the United Kingdom and 86 burns consultants. On average, these consultants are 13 years from retirement age. 22 will reach this age within the next decade. During this time, the UK population is expected to increase by 10%, translating to approximately another 6 consultant posts. Since there are only 2 UK recognized burns fellowships, many of the required consultants will have to seek training abroad. Conclusions Workforce planning is essential to avoid a short fall in the number of upcoming burns consultants. Plans must be in place to anticipate additional workload with a 10% population rise. With the current struggles of NHS funding, a comprehensive review of burns workforce planning should be undertaken to ensure that sufficient numbers of trainees are completing appropriate burns-specific training and are ready to fill these posts.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2TCjAD0
Vascularized Fibula Epiphysis Transfer for Pediatric Extremity Reconstruction: A Systematic Review and Meta-analysis
Background Vascularized fibula epiphysis transfer for pediatric extremity reconstruction intends to preserve growth potential. However, few cases are reported, and outcomes are poorly characterized. Methods Systematic review was performed through a MEDLINE search using keywords "pediatric" or "epiphyseal" and "vascularized fibula." Patients were divided into upper extremity or lower extremity groups. Functional and growth outcomes were assessed, and indications, pedicle, complications, and need for secondary surgery were recorded. Results Twenty publications with 62 patients were included. Mean age was 5.9 years, and mean follow-up was 5.8 years. Indications included sarcoma (60%), congenital deformity (21%), trauma (13%), and infection (6%). Anterior tibial pedicle was most common (63%) and was associated with significantly improved growth outcomes compared with the peroneal pedicle (23%; Pfrom #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2BpneZS
Correction of Tanzer Type IIB Constricted Ears via Z-shaped Double V-Y Advancement Flaps
Background Correction of Tanzer type IIB constricted ears requires sufficient expansion of the auricular skin to cover the reconstructed cartilaginous framework. To obtain an adequately sized skin cover, skin flap transposition from periauricular donor sites has been described; however, it remains challenging to obtain enough skin to enable satisfactory reconstruction. Herein, we describe a novel method that uses 2 local flaps comprising superoauricular, retroauricular, and preauricular soft tissue to expand the skin cover and correct Tanzer type IIB deformity. Methods Fifteen constricted ears in 15 patients were treated via this novel method from June 2013 to July 2017. Two adjoining V-Y advancement flaps shaped like a backward "Z" were created to expand the skin envelope of the upper one-third of the ear. The advancement of these 2 flaps toward each other expanded the skin of the upper one-third of the ear by creating a skin arch, which was then used to wrap the reconstructed cartilaginous framework. The auricular cartilage was refashioned via a method that combined several previously reported techniques. Results A satisfactory outcome was achieved in all 15 constricted ears, with resultant improvements in size and shape, and an elevated auricular position. Conclusions The preauricular, superoauricular, and retroauricular skin areas can be used to successfully expand the skin envelope of the upper auricle via the creation of 2 adjoining V-Y advancement flaps. This results in an ample skin cover with which to accommodate the auricular cartilaginous framework reconstructed by multiple techniques. This novel Z-shaped double V-Y advancement flap method can effectively correct Tanzer type IIB constricted ears.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2TF2kgI
The Impact of Resident Postgraduate Year Involvement in Body-Contouring and Breast Reduction Procedures: A Comprehensive Analysis of 9638 Patients
Background Given the rising popularity in body-contouring procedures (BCPs) in the United States, it is important to assess the currently unknown association between resident involvement and postoperative complications. As such, the aim of this study was to evaluate the impact of resident involvement on outcomes in BCPs using a large national database. Methods A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database was performed (2006–2012) to identify patients undergoing BCPs, using relevant Current Procedural Terminology codes. Outcome measures included postoperative complications, hospital length of stay, and operation time. Multivariate regression models were used to assess the impact of resident involvement and resident experience on outcomes. Results A total of 9638 cases were identified, of which 3311 involved resident participation. Resident involvement was associated with significantly higher rates of complications (7.8% vs 4.4%; P = 0.003) and longer operation times (180.7 vs 171.9 minutes; P = 0.005). For each year increase of resident postgraduate year, there was a significant decrease in odds of complications (odds ratio, 0.906; P = 0.013) and operative time (−2.7 minutes; P = 0.001). Conclusions Resident involvement in BCPs was associated with an increased rate of overall complications in a large, national database. However, the clinical significance of these outcomes may be debated. Increased postgraduate year experience as a surgical resident was inversely associated with overall complications. Guided resident autonomy and earlier exposure to BCPs could lead to an optimization of clinical outcomes and resident education.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2BoPfAV
Surgical Technique for Nasal Cleft Repair
Background Congenital nasal cleft is a very rare yet challenging deformity to reconstruct. Atypical craniofacial clefts that involve the nasal ala are designated as number 1 and number 2 under the Tessier classification system. These clefts typically present as notches in the medial one-third of either nasal ala and may be accompanied by a malpositioned cartilaginous framework. Nasal clefts are smaller and far less common than familiar clefts of the lip and palate, but they pose equally challenging reconstructive planning. Methods Our described technique relies on usage of existing nasal tissue near the cleft. Local tissue rearrangement using a laterally based rotational alar flap, a medially based triangular flap, and a nasal wall advancement flap restores normal anatomy and provides an aesthetically pleasing result. Results Five children with isolated nasal cleft were treated by the senior author (A.M.) between 2010 and 2017. All patients presented with clefts of the soft tissue with no underlying cartilaginous involvement. There were no postoperative complications. Excellent aesthetic outcome was achieved in all patients. Conclusion Isolated nasal cleft can be properly corrected with the described procedure in a single stage and with optimal result.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2TD2UeI
Face Transplantation for Granulomatosis With Polyangiitis (Wegener Granulomatosis): Technical Considerations, Immunological Aspects, and 3-Year Posttransplant Outcome
Background We report new data for a rare face transplant performed 3 years ago. Granulomatosis with polyangiitis (GPA) (Wegener) is a severe autoimmune necrotizing vasculitis and parenchymal inflammatory disease that can affect any organ including those of the craniofacial region. Skin involvement manifests as malignant pyoderma. This account (1) highlights the technical details of face transplantation for this unique indication, (2) reports the 3-year posttransplant outcome, and (3) describes relevant immunological aspects. Methods A Le Fort III near-total face and near-total scalp transplant was performed after extensive trauma and subsequent bone and soft tissue infection in a patient with GPA. Incisions were planned along facial aesthetic subunits. The vascular pedicle comprised the facial and superficial temporal arteries bilaterally. The functioning left eye was preserved and fitted into the donor tissues. Results The procedure took 21 hours, and transfusion was limited to 4 units of packed red cells. Early medical and surgical complications were successfully treated. At 3 years, acceptable aesthetic outcome was achieved with adequate color match and scalp hair growth. The patient has recovered light touch, temperature, and 2-point discrimination and has evidence of symmetric cheek elevation albeit with limited eyelid and frontalis function. GPA relapse did not occur. Four acute rejections were fully reversed. Conclusions This case represents a new underlying disease (trauma + GPA) leading to face transplantation and a unique clinical scenario where allografting was indicated for potentially life-threatening and sight-preserving reasons and not for mere functional and aesthetic concerns. Despite complexity, 3-year clinical outcome is encouraging, and the patient is no longer at risk for dural exposure, meningitis, and related morbidity.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2Bin5Yj
Application of Concatenated Arterialized Venous Flaps in Finger Reconstruction
Venous flaps from the distal volar forearm are said to be suitable flaps for finger reconstruction. The pliability of the forearm venous flap makes it easy to follow the curvature of the finger contour. The thickness of the flap makes it appropriate as a flap for finger resurfacing. Following the venous network at the palmar forearm, diverse patterns of the venous flaps can be designed. This article describes the use of a 2-concatenated paddle, flow-through arterialized venous flap design for simultaneous resurfacing of 2 separate defects on a single digit. A technique that can be used to reduce postoperative venous congestion will be highlighted in this article.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2TGNbvn
Medial Plantar Flap for Hand Reconstruction: A Systematic Literature Review and Its Application for Post–Sarcoma Excision
The reconstruction of soft tissue defects on the volar aspect of the hand represents a special challenge for the hand surgeon. Even though local and regional options have been described, in some cases because of their complexity, a free flap is preferred. The medial plantar free flap offers a unique reconstructive alternative by providing glabrous skin resurfacing for the palm and digits. The aim of this article is to present a systematic literature review on the use of the medial plantar free flap for hand surgery and a case report in which this flap was used for reconstructing a thenar eminence defect after sarcoma excision. Twenty-five relevant articles were found, and their findings are included in our study. The fasciocutaneous medial plantar flap and its musculocutaneous, flow-through, venous, perforator, and chimeric variants offer a wide range of reconstructive options for complex hand injuries.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2BnIfUN

MCs are capable of activating the fibroblasts and keratinocytes, the predominant cells involved in wound healing. MCs stimulate fibroblast proliferation during the proliferative phase via IL-4, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) to produce a new extracellular matrix (ECM). MC-derived mediators including fibroblast growth factor-2, VEGF, platelet-derived growth factor (PDGF), TGF-β, nerve growth factor (NGF), IL-4, and IL-8 contribute to neoangiogenesis, fibrinogenesis, or reepithelialization during the repair process. MC activation inhibition and targeting the MC-derived mediators are potential therapeutic strategies to improve wound healing through reduced inflammatory responses and scar formation.

Venous Congestion in Pedicled Frontal Branch Superficial Temporal Artery Flaps Reconstructions for Head and Neck Defects: A Review
The superficial temporal artery (STA) flap is a versatile flap for head and neck defect reconstruction. It can be based on the frontal branch of the STA and an islanded 360-degree rotation arc for various defects on the scalp, cheek, and auricular region. It provides a nonmicrosurgical option for reconstructing such defects, which is itself relatively easy to perform. However, venous congestion is a problem than often can cause worry to the clinician and hence preclude its use. In this review, we revisit this flap in head and neck reconstruction, with case examples used for reconstruction of defects on the scalp, maxilla, lip, ear, and retroauricular area. The STA flap in our review can be used either as a fasciocutaneous flap or with its fascia alone. The main issue with the STA flap is that it is generally a high-inflow flap with variable outflow. Venous congestion is frequently encountered in our practice, and adequate management of the venous drainage in the postoperative period is crucial in ensuring its success as a versatile and viable option for head and neck reconstruction.from #Head and Neck by Sfakianakis via simeraentaxei on Inoreader http://bit.ly/2BlP5dG
