Background: Radiculomegaly, or root gigantism, is a rare dental abnormality with important clinical implications. It is highly specific for oculo-facio-cardio-dental syndrome (OFCD), which places dentists at the forefront of diagnosis for this syndrome. Only one case of non-syndromic radiculomegaly has been reported in the literature since the description of OFCD in 1996. We present the second confirmed, non-syndromic/non-familial case and review the literature for dental treatments in patients with this dental finding. Methods: A review of the English-language literature was performed within PubMed for patients with radiculomegaly or OFCD. Teeth affected by radiculomegaly, gender, oro-dental findings, presence of OFCD syndrome, and dental treatment methods were recorded. Results: Sixty-seven cases of radiculomegaly and 92 OFCD cases were found in the literature. Only one confirmed case of non-syndromic/non-familial radiculomegaly existed prior to our report. Ten cases reported dental treatment or treatment plan details, and even fewer detailed the specific methods. Conclusions: Because dental anomalies, especially radiculomegaly, are a primary feature of OFCD, dentists should be aware of the clinical and radiographic features. Radiculomegaly poses a distinct challenge to dentists, and reports of dental therapy provided to these patients are sparse. Early diagnosis of the syndrome may prevent dental challenges and improve prognosis.

How effective and cost-effective are innovative combinatorial technologies and practices for supporting older people with long-term conditions to remain well in the community? An evaluation protocol for an NHS Test Bed in North West England
The Lancashire and Cumbria Innovation Alliance (LCIA) Test Bed is a partnership between the National Health Service in England, industry (led by Philips) and Lancaster University. Through the implementation of a combination of innovative health technologies and practices, it aims to determine the most effective and cost-effective ways of supporting frail older people with long-term conditions to remain well in the community. Among the Test Bed’s objectives are to improve patient activation and the ability of older people to self-care at home, reduce healthcare system utilisation, and deliver increased workforce productivity.
Methods and analysisPatients aged 55 years and over are recruited to four cohorts defined by their risk of hospital admission, with long-term conditions including chronic obstructive pulmonary disease, dementia, diabetes and heart failure. The programme is determined on an individual basis, with a range of technologies available. The evaluation is adopting a two-phase approach: phase 1 includes a bespoke patient survey and a mass matched control analysis; and phase 2 is using observational interviews with patients, and weekly diaries, action learning meetings and focus groups with members of staff and other key stakeholders. Phase 1 data analysis consists of a statistical evaluation of the effectiveness of the programme. A health economic analysis of its costs and associated cost changes will be undertaken. Phase 2 data will be analysed thematically with the aid of Atlas.ti qualitative software. The evaluation is located within a logic model framework, to consider the processes, management and participation that may have implications for the Test Bed’s success.
Ethics and disseminationThe LCIA Test Bed evaluation has received ethical approval from the Health Research Authority and Lancaster University’s Faculty of Health and Medicine Research Ethics Committee. A range of dissemination methods are adopted, including deliberative panels to validate findings and develop outcomes for policy and practice.

Morphological changes of hair melanosomes by aging
Summary
Various changes appear in hair by aging and graying is the most remarkable one. Changes in melanocytes have been well studied as the cause, however, little is known about the change of melanosomes which have a role of carrying melanin pigments into hair shafts. Using pigmented hairs of Japanese females from their age of 4 to 75, I isolated melanosomes and observed them. As a result, I found a significant change in the morphology of hair melanosomes with age. They were ellipsoidal on the whole and there was no age dependence in the major axis, while the minor axis significantly increased and its frequency distribution broadened with age. The anticipated volume of the melanosome of the oldest person hairs was about twice larger than that of child hairs. This enlargement of melanosome seems to be a cause of the age-related color change of pigmented hairs from brown to black.

IJMS, Vol. 19, Pages 689: Gonad Transcriptome Analysis of High-Temperature-Treated Females and High-Temperature-Induced Sex-Reversed Neomales in Nile Tilapia
International Journal of Molecular Sciences doi: 10.3390/ijms19030689
Authors: Li Sun Jian Teng Yan Zhao Ning Li Hui Wang Xiang Ji
Background: Nowadays, the molecular mechanisms governing TSD (temperature-dependent sex determination) or GSD + TE (genotypic sex determination + temperature effects) remain a mystery in fish. Methods: We developed three all-female families of Nile tilapia (Oreochromis niloticus), and the family with the highest male ratio after high-temperature treatment was used for transcriptome analysis. Results: First, gonadal histology analysis indicated that the histological morphology of control females (CF) was not significantly different from that of high-temperature-treated females (TF) at various development stages. However, the high-temperature treatment caused a lag of spermatogenesis in high-temperature-induced neomales (IM). Next, we sequenced the transcriptome of CF, TF, and IM Nile tilapia. 79, 11,117, and 11,000 differentially expressed genes (DEGs) were detected in the CF–TF, CF–IM, and TF–IM comparisons, respectively, and 44 DEGs showed identical expression changes in the CF–TF and CF–IM comparisons. Principal component analysis (PCA) indicated that three individuals in CF and three individuals in TF formed a cluster, and three individuals in IM formed a distinct cluster, which confirmed that the gonad transcriptome profile of TF was similar to that of CF and different from that of IM. Finally, six sex-related genes were validated by qRT-PCR. Conclusions: This study identifies a number of genes that may be involved in GSD + TE, which will be useful for investigating the molecular mechanisms of TSD or GSD + TE in fish.

Computed tomography findings after radiofrequency ablation in locally advanced pancreatic cancer
Abstract
Purpose
The purpose of the study was to provide a systematic evaluation of the computed tomography(CT) findings after radiofrequency ablation (RFA) in locally advanced pancreatic cancer(LAPC).
Methods
Eighteen patients with intra-operative RFA-treated LAPC were included in a prospective case series. All CT-scans performed prior to RFA and 1 week and 3 months of post-RFA, according to standard regimen, were assessed by two radiologists in consensus, using standardized radiological scoring lists.
Results
51 CT-scans were assessed. One week after RFA, the ablation zone was visible in all patients as a (partially) sharply defined (83%), heterogeneous area (94%). At 3 months of follow-up, the ablation zone was completely invaded by tumor in 67% of patients and still present, but decreased in 33%. In two patients (11%), local thrombosis and/or occlusion of the superior mesenteric vein occurred. The occlusions persisted without clinical consequences and the thrombosis disappeared. A peripancreatic fluid collection was visible 1 week after RFA in 3 patients, wherein the ablation zone extended ventrally outside of the pancreas.
Conclusions
Directly after RFA for LAPC, a well-defined ablation zone is visible on CT-imaging. This ablation zone is usually replaced by tumor ingrowth after 3 months. Moreover, the ablation zone regularly included vascular structures, with rare asymptomatic venous occlusion or thrombosis and without adverse effects on arteries.

Response of Retinoic Acid in Patients with Radioactive Iodine-Refractory Thyroid Cancer: A Meta-Analysis.
Oncol Res Treat. 2018;41(3):100-104
Authors: Pak K, Shin S, Kim SJ, Kim IJ, Chang S, Koo P, Kwak J, Kim JH
Abstract
PURPOSE: The purpose of this study was to evaluate the response of retinoic acid (RA) in radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC).
METHODS: Systematic searches of MEDLINE (from inception to December 2016) and of EMBASE (from inception to December 2016) were performed for English-language publications on thyroid cancer treated with RA. Studies were classified according to the response criteria used: (1) 123I or 131I whole body scintigraphy (WBS), (2) serum thyroglobulin (Tg) level, (3) the response evaluation criteria in solid tumors (RECIST) version 1.0, and (4) World Health Organization (WHO) criteria.
RESULTS: Disease response rates as determined by WBS ranged widely between 6.2% and 46.1% with a pooled disease response rate of 27.6% (95% confidence interval: 21.7-34.0%). Response rates as determined by Tg level ranged from 56.6% to 83.3% (pooled response rate 61.3% (51.0-70.9%)), RECIST response rates from 0% to 45.5% (pooled response rate 17.0% (1.4-44.5%)), and according to WHO criteria, the pooled response rate was 30.8% (12.7-52.7%).
CONCLUSIONS: A minority of patients with RAI-refractory DTC respond to RA treatment.

Abstract
Introduction The purpose of this study was to evaluate the incidence of incidental differentiated thyroid carcinoma in thyroid operations for a benign preoperative diagnosis, to identify the risk factors involved and to risk stratify the cancer patients according to the 2015 American Thyroid Association (ATA) guidelines. Materials and methods The study was a retrospective review of all thyroidectomy operations performed in a single institution (January 2004 to January 2009). We excluded patients with a preoperative diagnosis of thyroid malignancy. Results Incidental differentiated thyroid carcinoma was diagnosed in 282/1369 patients (21%). The incidental group had a significantly higher number of males (19% vs 14%, P = 0.033) and a higher number of patients with histopathological evidence of thyroiditis (35% vs 25%, P = 0.004). There was a higher number of lymph nodes present in the incidental group but numbers did not reach statistical significance (17% vs 13%, P = 0.079). There were 270 cases in the ATA low-risk group (96%) and 12 cases in the ATA intermediate-risk group (4%). Patients with an ATA intermediate risk had a statistically higher number of capsule invasion, extrathyroidal extension and angioinvasion (P < 0.001, P < 0.001 and P < 0.001, respectively). Overall, 22% of patients with an incidental differentiated thyroid carcinoma should be considered for radioactive iodine 131I treatment. 29 of the 191 patients in American Joint Committee on Cancer stage I should be considered for radioactive iodine treatment (15%). Conclusions Males and patients with thyroiditis are at a higher risk for an incidental differentiated thyroid carcinoma. One of every five of patients diagnosed with cancer will need radioactive iodine treatment, even some patients with stage I disease.

Abstract
Objective Hearing loss (HL) is the most common sensory-neural defect and the most heterogeneous trait in humans, with the involvement of >100 genes, which make a molecular diagnosis problematic. Next-generation sequencing (NGS) is a new strategy that can overcome this problem. Study Design Descriptive experimental study. Setting Diagnostic laboratory. Subjects and Methods A comprehensive family history was obtained, and clinical evaluations and pedigree analysis were performed in a family with multiple individuals with HL. As the first tier, GJB2 was sequenced, and genetic linkage analysis of DFNB1A/B was performed to rule out the most common cause of the disease. Targeted NGS was used to unravel the molecular etiology of the disease in the HL-associated genes in the proband. Two homozygous variants remained in OTOF after proper filtration. Cosegregation and in silico analysis were done. Preimplantation genetic diagnosis (PGD) was accomplished via linkage analysis and direct sequencing of the pathogenic variant. Results Clinical evaluations suggested autosomal recessive nonsyndromic HL. Two homozygous variants, c.367G>A (p.Gly123Ser) and c.1392+1G>A, were identified in cis status. c.1392+1G>A met the criteria for being pathogenic according to the variant interpretation guideline of the American College of Medical Genetics and Genomics. PGD was successfully performed to prevent the recurrence of the disease in the related family. Conclusion A novel OTOF mutation causing HL was identified. Here, we report the effectiveness of the combined application of targeted NGS and PGD in diagnosis and prevention of hereditary HL.

Abstract
Objective To design and assess an advanced pediatric airway management course, through simulation-based team training and with multiple disciplines, to emphasize communication and cooperation across subspecialties and to provide a common skill set and knowledge base. Methods Trainees from anesthesiology, emergency medicine, critical care, pediatric surgery, and otolaryngology at a tertiary children's hospital participated in a 1-day workshop emphasizing airway skills and complex airway simulations. Small groups were multidisciplinary to promote teamwork. Participants completed pre- and postworkshop questionnaires. Results Thirty-nine trainees participated over the 3-year study period. Compared with their precourse responses, participants' postcourse responses indicated either agreement or strong agreement that the multidisciplinary format (1) helped in the development of team communication skills and (2) was preferred over single-discipline training. Improvement in confidence in managing critical airway situations and in advanced airway management skills was significant ( P < .05). Eighty-one percent of participants had improved confidence in following the hospital's critical airway protocol, and 64% were better able to locate advanced airway management equipment. Discussion Multiple subspecialists manage pediatric respiratory failure, where successful care requires complex handoffs and teamwork. Multidisciplinary education to teach advanced airway management, teamwork, and communication skills is practical and preferred by learners and is possible to achieve despite differences in experience. Future study is required to better understand the impact of this course on patient care outcomes. Implications for Practice Implementation of a pediatric difficult airway course through simulation-based team training is feasible and preferred by learners among multiple disciplines. A multidisciplinary approach exposes previously unrecognized knowledge gaps and allows for better communication and collaboration among the fields.

Otolaryngol Head Neck Surg. 2018 Feb 01;:194599818756599
Authors: Cramer JD, Shuman AG, Brenner MJ
Abstract
Objective The aim of this report is to present a cohesive evidence-based approach to reducing venous thromboembolism (VTE) in otolaryngology-head and neck surgery. VTE prevention includes deep venous thrombosis and pulmonary embolism. Despite national efforts in VTE prevention, guidelines do not exist for otolaryngology-head and neck surgery in the United States. Data Sources PubMed/MEDLINE. Review Methods A comprehensive review of literature pertaining to VTE in otolaryngology-head and neck surgery was performed, identifying data on incidence of thrombotic complications and the outcomes of regimens for thromboprophylaxis. Data were then synthesized and compared with other surgical specialties. Conclusions We identified 29 articles: 1 prospective cohort study and 28 retrospective studies. The overall prevalence of VTE in otolaryngology appears lower than that of most other surgical specialties. The Caprini system allows effective individualized risk stratification for VTE prevention in otolaryngology. Mechanical and chemoprophylaxis ("dual thromboprophylaxis") is recommended for patients with a Caprini score ≥7 or patients with a Caprini score of 5 or 6 who undergo major head and neck surgery, when prolonged hospital stay is anticipated or mobility is limited. For patients with a Caprini score of 5 or 6, we recommend dual thromboprophylaxis or mechanical prophylaxis alone. Patients with a Caprini score ≤4 should receive mechanical prophylaxis alone. Implications for Practice Otolaryngologists should consider an individualized and risk-stratified plan for perioperative thromboprophylaxis in every patient. The risk of bleeding must be weighed against the risk of VTE when deciding on chemoprophylaxis.

Music Appreciation after Cochlear Implantation in Adult Patients: A Systematic Review.
Otolaryngol Head Neck Surg. 2018 Feb 01;:194599818760559
Authors: Riley PE, Ruhl DS, Camacho M, Tolisano AM
Abstract
Objective The cochlear implant (CI) improves quality of life for people who are severely and profoundly deafened, allowing implantees to perceive speech at levels similar to those of individuals with normal hearing. However, patients with CIs generally report a reduced appreciation of music after implantation. We aimed to systematically review the English-language literature for studies evaluating music enjoyment and perception among adult patients with CIs. Data Sources A systematic review of PubMed/MEDLINE, Scopus, Embase, and the Cochrane Library. Review Methods The PRISMA statement was utilized to identify English-language studies reporting music appreciation among adults with CIs. Two independent reviewers performed searches through May 2017. Included studies investigated parameters related to music enjoyment and music perception, including (1) pitch and timbre perception, (2) noise-canceling algorithms, and (3) the presence of dissonant chords, lyrics, or visual cues. Results A total of 508 articles were screened for relevance. Forty-one full-text articles were evaluated, and 18 met final inclusion criteria. Studies used heterogeneous methods of outcome measurement for identifying music appreciation. The outcome measures suggest that rhythm and lyrics are important components of enjoyment. Patients with CIs had difficulty with pitch and timbre perception. Conclusion The heterogeneous outcome measures identified in this systematic review suggest that rhythm and lyrics are important components of enjoyment, while patients with CIs had difficulty with pitch and timbre perception. Because there is no standardized reporting metric for music appreciation among adult patients with CIs, a standardized validated outcome-measuring tool is warranted.

Abstract
Objective Tympanostomy tube (TT) insertion is the most common ambulatory surgery performed on children. American Academy of Otolaryngology-Head and Neck Surgery Founda-tion (AAO-HNSF) Clinical Practice Guidelines (CPGs) recommend hearing testing for all pediatric TT candidates. The aim of this study was to assess audiometric testing in this population. Study Design Retrospective population-based cohort study. Setting All hospitals in the Canadian province of Ontario. Subjects and Methods All patients 12 years of age and younger who underwent at least 1 TT procedure between January 1993 and June 2016. The primary outcomes were the percentage of patients who underwent a hearing test within 1 year before and/or 1 year after surgery. Results A total of 316,599 bilateral TT procedures were performed during the study period (1993 to 2016). Presurgical hearing tests increased from 55.7% to 74.9%, and postsurgical hearing tests increased from 42.2% to 68.9%. Younger surgeons demonstrated a greater adherence to the CPGs (relative risk [RR], 1.22; 95% CI, 1.08-1.38; P = .001). Remarkably, there was not a spike in preoperative hearing tests following the introduction of the CPGs in 2013 (RR, 1.12; 95% CI, 0.85-1.47; P = .432). Presurgical hearing testing ranged from 26.1% to 83.5% across health regions. Conclusion In this cohort of children who underwent TT placement, the trends of preoperative and postoperative audiometric testing are increasing but are still lower than recommended by the CPGs, despite a tripling of practicing audiologists. This study describes the current state of testing in Ontario and highlights issues of access to audiology services, possible parent preferences, and the importance of ongoing continuing medical education for all health care practitioners.

Otolaryngol Head Neck Surg. 2018 Feb 01;:194599818758270
Authors: Chaiet SR, Yoshikawa N, Sturm A, Flanary V, Ishman S, Streed CG
Abstract
Currently, there are limited resources and training available for otolaryngologists and otolaryngology practice personnel to provide gender-affirming care for transgender or gender nonconforming patients. This unique patient population may present to our offices for gender-specific care or with complaints of the ear, nose, and throat unrelated to gender identity. Our current practice has unintentional but direct consequences on our patients care, as transgender patients often report negative experiences in the healthcare setting related to their gender identity. The absence of resources and training is also seen in other specialties. Physicians who create an environment where patients of all gender identities feel welcome can better meet their patients' health care needs. In addition, otolaryngologists can play a role in easing the gender dysphoria experienced by transgender patients. We suggest educational content should be created for and made available to otolaryngologists and office staff to provide gender-affirming care.

Cancers, Vol. 10, Pages 62: Tumor Resistance against ALK Targeted Therapy-Where It Comes From and Where It Goes
Cancers doi: 10.3390/cancers10030062
Authors: Geeta Sharma Ines Mota Luca Mologni Enrico Patrucco Carlo Gambacorti-Passerini Roberto Chiarle
Anaplastic lymphoma kinase (ALK) is a validated molecular target in several ALK-rearranged malignancies, particularly in non-small-cell lung cancer (NSCLC), which has generated considerable interest and effort in developing ALK tyrosine kinase inhibitors (TKI). Crizotinib was the first ALK inhibitor to receive FDA approval for ALK-positive NSCLC patients treatment. However, the clinical benefit observed in targeting ALK in NSCLC is almost universally limited by the emergence of drug resistance with a median of occurrence of approximately 10 months after the initiation of therapy. Thus, to overcome crizotinib resistance, second/third-generation ALK inhibitors have been developed and received, or are close to receiving, FDA approval. However, even when treated with these new inhibitors tumors became resistant, both in vitro and in clinical settings. The elucidation of the diverse mechanisms through which resistance to ALK TKI emerges, has informed the design of novel therapeutic strategies to improve patients disease outcome. This review summarizes the currently available knowledge regarding ALK physiologic function/structure and neoplastic transforming role, as well as an update on ALK inhibitors and resistance mechanisms along with possible therapeutic strategies that may overcome the development of resistance.

Here, we provide a method and apparatus for real-time compensation of the thermal effect of single free-standing piezoresistive microcantilever-based biosensors. The sensor chip contained an on-chip fixed piezoresistor that served as a temperature sensor, and a multilayer microcantilever with an embedded piezoresistor served as a biomolecular sensor. This method employed the calibrated relationship between the resistance and the temperature of piezoresistors to eliminate the thermal effect on the sensor, including the temperature coefficient of resistance (TCR) and bimorph effect. From experimental results, the method was verified to reduce the signal of thermal effect from 25.6 μV/°C to 0.3 μV/°C, which was approximately two orders of magnitude less than that before the processing of the thermal elimination method. Furthermore, the proposed approach and system successfully demonstrated its effective real-time thermal self-elimination on biomolecular detection without any thermostat device to control the environmental temperature. This method realizes the miniaturization of an overall measurement system of the sensor, which can be used to develop portable medical devices and microarray analysis platforms.

The inflammatory process plays a major role in the prognosis of dengue. In this context, the eicosanoids may have considerable influence on the regulation of the Dengue virus-induced inflammatory process. To quantify the molecules involved in the cyclooxygenase and lipoxygenase pathways during Dengue virus infection, plasma levels of thromboxane A2, prostaglandin E2 and leukotriene B4; mRNA levels of thromboxane A2 synthase, prostaglandin E2 synthase, leukotriene A4 hydrolase, cyclooxygenase-2 and 5-lipoxygenase; and the levels of lipid bodies in peripheral blood leukocytes collected from IgM-positive and IgM-negative volunteers with mild dengue, and non-infected volunteers, were evaluated. Dengue virus infection increases the levels of thromboxane A2 in IgM-positive individuals as well as the amount of lipid bodies in monocytes in IgM-negative individuals. We suggest that increased levels of thromboxane A2 in IgM-positive individuals plays a protective role against the development of severe symptoms of dengue, such as vascular leakage.
