	The first objective of this study is to present an overview of the human cadaver studies aimed to determine the biomechanics of the head-neck in a simulated rear crash. The need for kinematic studies to better understand the mechanisms of load transfer to the human head-neck complex is emphasized. Based on this need, a methodology is developed to delineate the dynamic kinematics of the human head-neck complex. Intact human cadaver head-neck complexes were subjected to postero-anterior impact using a mini-sled pendulum device. The integrity of the soft tissues including the musculature and skin were maintained. The kinematic data were recorded using high-speed photography coupled with retroreflective targets placed at various regions of the human head-neckcomplex. The overall and segmental kinematics of the entire head-neck complex, and the localized facet joint motions were determined. During the initial stages of loading, a transient decoupling of the head occurred with respect to the neck exhibiting a lag of the cranium. The upper cervical spine-head undergoes local flexion concomitant with a lag of the head while the lower cervical spinal column is in local extension. This establishes a reverse curvature to the cervical head-neck complex. With continued loading, head motion ensues and approximately at the end of the loading phase, the entire head-neck complex is under the extension mode with a single curvature. In contrast, the lower cervical spine facet joint kinematics show varying compression and sliding. While both the anterior and posterior-most regions of the facet joint slide, the posterior-most region (mean: 2.84 mm) of the joint compresses more than the anterior-most (mean: 2.02 mm) region. These varying kinematics at the ends of the facet joint result in a pinching mechanism. These biomechanical kinematic findings may be correlated to the presence of headaches and neck pain (Lord, Bogduk et al. 1992; Barnsley, Lord et al. 1995), based on the unique human head-neck anatomy at the upper cervical spine region and the associated facet joint characteristics, and clinical studies.

	Background. Assessment of hand grip strength is vital for the evaluation of upper limb impairments and effective exercise prescription. Present study primarily aimed to investigate the effect of head-neck positions on the hand grip strength in healthy young adults. Secondarily, the present study compared hand grip strength between left versus right hand in different head-neckpositions. Methods. Healthy young adults (age 19 – 30 year; n = 40) participated in this cross-sectional study. Hand grip strength was assessed in three head-neck positions (neutral, rotation left, and rotation right) using the standard adjustable Jamar hand dynamometer. Results. Hand grip strength in both sides (left and right) was greatest in the head-neck neutral position. Hand grip strength measured in head-neck left rotation position displayed the least strength in both sides. There was no significant difference noted between left and right side hand grip strength measured in head-neck neutral and right rotation positions. However, there was a significant difference noted between left and right side hand grip strength measured in head-neck left rotation positions. There was no significant effect of head-neck positions on hand grip strength noted in both sides. Conclusions. Hand grip strength was highest in the head-neck neutral position followed by head-neck rotation to the right. However, head-neck positions did not significantly affect hand grip strength in healthy young adults. Further studies assessing the hand grip strength in different neckpositions in patients with neck pain and upper limb dysfunction may have significant implications for the assessment of hand grip strength.

	AIM: To find the prevelance and Incidence of head and neck cancer cases of other total body malignancies in our cancer centre. MATERIALS & METHODS: This is a retrospective analysis which was done in curie Manavata Cancer Centre in northern Maharashtra from 14th May 2007 to 30th November 2014. Total cases operated were 14368 out of which 2017 were head and neck cancers. RESULTS: Incidence of Head & Neck cancer cases in our 7 years study was around 14.03% of other total body malignancies. Males are more affected by Head & Neck cancer for around 82.01% than females contributing which is around 17.9%. Oral cavity malignancies contribute around 76.6% out of all head & neck cancer cases. Tongue cancers are more commonly affected which is around 33.4% followed by Buccal mucosa which is 29.77%. The mortality rate is high in buccal mucosa (32.35%) followed by tongue (27.4%). CONCLUSION: This retrospective study hopes to quantify and analyze the spectrum of Head and neck cancer out of the other total body malignancies. A tremendous effort is needed to identify such high prevelance, generate awareness and establish treatment modalities to meet this challenging statistical analysis.

	Sarcomas are malignant neoplasms originating from mesodermal tissues and constitute less than 1% of body's tumors, including those of the head and neck region. 5–15% of adult sarcomas are in the head and neck region (20% from bones and cartilages and 80% in soft tissues). Commonly encountered sarcomas in the head and neck region are - osteosarcoma, rhabdomyosarcoma, malignant fibrous histiocytoma, fibrosarcoma and angiosarcoma. This article reviews the available literature on head and necksarcomas.

	Objectives: To investigate the effect of different induced head-neck-jaw postures on head-neck relocation error among healthy subjects. Methods: 30 healthy adult male subjects participated in this study. Cervicocephalic kinesthetic sense was measured while standing, habitual sitting, habitual sitting with clenched jaw and habitual sitting with forward head posture during right rotation, left rotation, flexion and extension using kinesthetic sensibility test. Results: Head-neck relocation error was least while standing, followed by habitual sitting, habitual sitting with forward head posture and habitual sitting with jaw clenched. However, there was no significant difference in error between different tested postures during all the movements. Conclusions: To the best of our knowledge, this is the first study to see the effect of different induced head-neck-jaw postures on head-neck position sense among healthy subjects. Assuming a posture for a short duration of time doesn't affect head-neck relocation error in normal healthy subjects.

	Introdução: Com as demonstrações da relação entre inflamação, desregulação microbiológica e câncer, a higiene oral precária pode ser um fator risco. Objetivo: Verificar se a condição de higiene está associada com a ocorrência dos cânceres de cabeça e pescoço. Material e método: Foram analisadas variáveis de condição de higiene bucal, como frequência de escovação, dentes perdidos, necessidade e uso de prótese e visita regular ao dentista num estudo caso-controle, com pacientes de cinco hospitais do estado de São Paulo, pareados por sexo e idade, do projeto multicêntrico ,,Genoma do Câncer de Cabeça e Pescoço\" (GENCAPO). Resultados: As neoplasias malignas mais frequentes foram as de bordo de língua (11,41%) e base de língua (10,92%). A análise estatística bivariada encontrou valores de Odds ratio abaixo de 1 para as variáveis: ,,escova 1x\" (OR=0,33; IC0,25-0,44), ,,escova 2x\" (OR=0,42;IC0,35-0,52), ,,usa fio sempre\" (OR=0,19;IC0,13-0,27), ,,usa fio às vezes\" (OR=0,19;IC0,15-0,24), ,,dentista todo ano\" (OR=0,29;IC0,22-0,37), ,,higiene boa\" (OR=0,21;IC0,166-0,27) e ,,higiene regular\" (OR=0,19;IC0,16-0,25) e acima de 1 para ,,sangra sempre\" (OR=2,40;IC1,40-4,09), ,,usa total\" (OR=1,99;IC1,54-2,56), ,,6 ou mais dentes perdidos\" (OR=3,30;IC2,67-4,08). A regressão logística multivariada encontrou significância para ,,escovar os dentes pelo menos 2x ao dia\" (OR=0,53;IC0,37-0,75), ,,fio sempre\" (OR=0,16;IC0,80-0,33) e para variável ,,6 ou mais dentes perdidos\" (OR=3,86;IC2,67-5,57). Discussão: Os dados mostram a necessidade de cuidados orais e indicam que higiene precária pode ser um fator de risco. Conclusão: Bons hábitos de higiene bucal possuem relação inversa com ocorrência de câncer em cabeça e pescoço e esses pacientes tem mais comorbidades bucais. Introduction: As demonstrations of the relationship between inflammation, microbiological dysregulation and cancer, poor oral hygiene can be adapted for cancers. Objective: To verify if the hygiene condition is associated with the occurrence of head and neck cancers. Material and method: The variables of oral hygiene condition, such as toothbrushing frequency, missing teeth, need and use of prosthesis and regular visit to the dentist in a case-control study were analyzed with patients from five hospitals in the state of São Paulo, paired by sex and age, of the multicenter project ,,Genoma do Câncer de Cabeça e Pescoço\" (GENCAPO). Results: The most frequent malignancies were those of the tongue border (11.41%) and tongue base (10.92%). The bivariate statistical analysis found odds ratio values below 1 for the variables\' 1x brush \'(OR = 0.33; IC0.253-0.44),\' 2x brush \'(OR = 0.42; IC0.34-0.52),\' floss (OR = 0.19, IC0.13-0.27), \'sometimes uses floss\' (OR = 0.19, IC0.15-0.24), \'dentist every year\' (OR = 0.29, IC0.22-0.37), (OR = 0.21, IC0.167-0.27) and \'regular hygiene\' (OR = 0.19, IC0.156-0.25) and above 1 for \'always bleeds\' (OR = 2.40, CI 1.40-4.09), \'total use\' (OR = 1,99, IC1,54-2,56), \'6 or more missing teeth\' (OR = 3,30, IC2,67-4,08). Multivariate logistic regression found significance for \'brushing the teeth at least 2x a day\' (OR = 0.53, IC0.37-0.75), \'always wire\' (OR = 0.16, IC0.80-0.32) and for variable \'6 or more lost teeth \'(OR = 3.86, IC2.67-5.57). Discussion: Data show the need for oral care and indicate that poor hygiene may be a risk factor. Conclusion: Good habits of oral hygiene have an inverse relation with the occurrence of head and neck cancer and these patients have more oral comorbidities.

	Background  Head and neck pain is an atypical presentation of acute aortic dissection. Classic teaching associates this pain with proximal dissections, but this has not been extensively studied. Methods  Patients enrolled in the International Registry of Acute Aortic Dissection from January 1996 to March 2015 were included in this study. We analyzed the demographics, presentation, treatment, and outcomes of Type A aortic dissection patients presenting with head and neck pain ( n  = 812, 25.8%) and compared it with those without these symptoms ( n  = 2,341, 74.2%). Results  Patients with head and neck pain were more likely to be white, female, with a family history of aortic disease. Patients with head and neck pain had higher percentages of back pain (43.3% vs. 37.5%, p  = 0.005) and chest pain (87.6% vs. 79.3%, p  < 0.001). On imaging, a higher percentage of those with head and neck pain had arch vessel involvement (44.3% vs. 38%, p  = 0.010) and intramural hematoma (11.7% vs. 8.1%, p  = 0.003). Surgical management was more common in patients with head and neck pain (89.8% vs. 85.2%, p  = 0.001). Regarding outcomes, patients with head and neck pain had significantly higher rates of stroke than those without head and neck pain (13% vs. 9.9%, p  = 0.016); however, overall mortality was lower for those with head and neck pain (19.5% vs. 23%, p  = 0.038). Those with head and neck pain only had higher overall mortality compared to those with head and neck pain with chest or back pain (34.6% vs. 19.9%, p  = 0.013). A logistic regression of mortality revealed that preoperative hypotension and age > 65 years were significantly associated with increased mortality. Conclusion  Presence of head and neck pain in Type A dissection is associated with more arch involvement, intramural hematoma, and stroke. When isolating those with head and neck pain only, there appear to be a higher rate of comorbidity burden and higher overall mortality.

	INTRODUCTION: Treatment of elderly patients is in many ways different from that for younger ones. The aim of the present study was to identify the particular characteristics and needs of elderly patients suffering from head and neck cancer. From these patterns, considerations for this special group can be deduced. Patients and Material The subjects for this study consisted of 376 patients suffering from head and neck cancer that were treated between 1999 and 2008, 99 (26.3.%) of whom were older than 70 years and were evaluated retrospectively concerning smoking/alcohol abuse, ASA status, kind of malignant neoplasm, localization and treatment. RESULTS: The male-female ratio was 53:46, and mean age, 79 years (71 - 98). Out of 95 patients with a squamous cell carcinoma, 4 patients had a verrucous form. Out of 99 patients, 26 had a maxillary carcinoma and 12 patients had experienced previous non-head-and-neck cancer. An ASA score of 2 or 3 was found in 86 of the patients. CONCLUSION: The group of patients with head and neck cancer who were older than 70 years was characterized by a higher portion of female patients, a higher number of maxillary carcinomas, and a higher prevalence of previous second cancer. Making decisions in cancer therapy for elderly patients is challenging. Patients suffering from operable head and neck cancer should be treated with curative intent and with regard to quality of life if a careful assessment of comorbidities is performed preoperatively.

A maioria dos pacientes é diagnosticada em estágios avançados da doença e ainda não existe nenhum marcador sensível e específico para o comportamento agressivo deste tumor. Portanto, uma detecção precoce e biomarcadores de prognóstico são altamente necessárias para uma administração mais racional da doença. A hipermetilação de ilhas CpGs é um dos mecanismos epigenéticos mais importantes que levam a um silenciamento gênico em tumores e tem sido extensivamente utilizados para a identificação de biomarcadores. Neste estudo foram combinados as análises de Rapid Substractive Hybridization (RaSH) e microarray de uma maneira hierárquica para selecionar genes que, supostamente, são reativados pelo agente desmetilante 5`'Aza'2`'deoxicitidina (5Aza'dC) em linhagens celulares derivados de carcinoma de cabeça e pescoço (FaDu, UM' SCC'14A, UM'SCC'17A e UM'SCC'38). Esta análise combinada identificou 78 genes dos quais 35 foram reativados em, pelo menos, 2 linhagens celulares e apresentavam ilha CpG nas suas regiões 5`. A reativação de três destes 35 genes (CRABP2, MX1 e SLC15A3) foi confirmada por PCR em tempo real (Fold change ≥ 3). O seqüenciamento de bissulfito de sódio das suas ilhas CpGs revelou que eles estão, de fato, diferencialmente metilados em linhagens celulares derivadas de carcinoma de cabeça e pescoço. Foram detectadas uma maior freqüência de hipermetilação dos genes CRABP2 (58.1% para a região 1) e MX1 (46.3%) em amostras primárias de câncer de cabeça e pescoço quando comparados a linfócitos de indivíduos saudáveis utilizando o PCR de metilação específica (MSP). Finalmente a ausência da proteína CRABP2 foi associada com... Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous disease affecting the epithelium of the oral cavity, pharynx and larynx. Most patients are diagnosed at late stages of the disease and no sensitive and specific predictors of aggressive behavior have been identified yet. Therefore, early detection and prognostic biomarkers are highly desirable for a more rational management of the disease. Hypermethylation of CpG islands is one of the most important epigenetic mechanisms that leads to gene silencing in tumors and has been extensively used for the identification of biomarkers. In this study, we combined Rapid Subtractive Hybridization (RaSH) and microarray analysis in a hierarchical manner to select genes that are putatively reactivated by the demethylating agent 5'aza'2''deoxycytidine (5Aza'dC) in HNSCC cell lines (FaDu, UM'SCC'14A, UMSCC'17A, UM'SCC'38A). This combined analysis identified 78 genes of which 35 were reactivated in at least 2 cell lines and harbored a CpG island at their 5' region. Reactivation of three out of these 35 genes (CRABP2, MX1 and SLC15A3) was confirmed by qRT'PCR (fold change ≥ 3). Bisulfite sequencing of their CpG islands revealed that they are indeed differentially methylated in the HNSCC cell lines. Using Methylation Specific PCR (MSP), we detected a higher frequency of CRABP2 (58.1% for region 1) and MX1 (46.3%) hypermethylation in primary HNSCC, when compared to lymphocytes from healthy individuals. Finally, absence of the CRABP2 protein was associated with decreased disease'free survival rates, supporting a potential use of CRABP2 expression as a prognostic biomarker for HNSCC patients

	Objective To investigate the risks of mild traumatic brain injury and neck injury associated with head banging, a popular dance form accompanying heavy metal music. Design Observational studies, focus group, and biomechanical analysis. Participants Headbangers. Main outcome measures Head Injury Criterion and Neck Injury Criterion were derived for head banging styles and both popular heavy metal songs and easy listening music controls. Results An average head banging song has a tempo of about 146 beats per minute, which is predicted to cause mild head injury when the range of motion is greater than 75°. At higher tempos and greater ranges of motion there is a risk of neck injury. Conclusion To minimise the risk of head and neck injury, head bangers should decrease their range of head and neck motion, head bang to slower tempo songs by replacing heavy metal with adult oriented rock, only head bang to every second beat, or use personal protective equipment.

	RESUMEN Introducción: La radioterapia es una de las variantes de tratamiento más antiguas con que contamos hoy día para curar los pacientes afectos de neoplasias malignas, pero debe ser cuidadosamente seleccionada en pacientes pediátricos. Objetivo: Evaluar la respuesta al tratamiento radiante en niños con tumores de cabeza y cuello. Métodos: Se realizó un estudio descriptivo, retrospectivo lineal, donde se incluyeron 26 pacientes ingresados en el Servicio de Oncocirugía del hospital "William Soler" desde enero de 2000 a enero de 2013, con diferentes tipos de tumores malignos de cabeza y cuello y edades comprendidas entre 1 y 18 años. Se tuvieron en cuenta los efectos tóxicos a largo plazo del tratamiento radiante, asociado o no a tratamiento quimioterápico adyuvante o concurrente y a la cirugía. Resultados: Todos los pacientes recibieron radioterapia corporal externa, el 73,1 % de los casos recibió quimioterapia adyuvante en su mayoría con diagnóstico de linfomas y 7,7 % recibió quimioterapia concurrente. Esta última en dos pacientes: uno con sarcoma facial y otro con carcinoma de parótida. Cinco pacientes (19,2 %) solo recibieron cirugía y radioterapia como tratamiento: dos casos con neuroblastoma, un caso con sarcoma facial y dos con hemangiopericitomas. Conclusión: El estudio demostró la gran utilidad del empleo de la radioterapia en el control de las enfermedades malignas de la infancia localizadas en cabeza y cuello.

	O tratamento do câncer de cabeça e pescoço e a dificuldade de comunicação decorrente da laringectomia interferem de maneira significativa na qualidade de vida das pessoas acometidas, principalmente quanto aos aspectos funcionais, psicológicos e sociais. Este estudo teve como o objetivo avaliar a qualidade de vida relacionada à saúde (QVRS) de pessoas com câncer de cabeça e pescoço. Trata-se de um estudo exploratório com metodologia quantitativa, do tipo transversal. A coleta de dados foi realizada no período de maio a setembro de 2015, com 100 pessoas com câncer de cabeça e pescoço, divididas em dois grupos: G1: pessoas laringectomizadas, G2: pessoas não laringectomizadas. Para isto, foi utilizado um aplicativo de comunicação alternativa instalado em tablet e foram aplicados o Critério de Classificação Econômica Brasil (CCEB) e a escala Functional Assessment Cancer Therapy (FACT-H&N). Para a análise dos dados foram utilizados o teste exato de Fisher, teste de Kruskal-Wallis, Ancova e estatística descritiva. Como resultados observou-se a prevalência de pessoas do sexo masculino, com faixa etária entre 59 e 74 anos , casadas, aposentadas não ativas, com baixa escolaridade e baixo nível socioeconômico. Os sujeitos participantes de ambos os grupos avaliaram sua qualidade de vida global, de um modo geral, como satisfatória sendo que as funções mais acometidas foram: bem estar emocional e bem estar funcional. Quanto às comparações dos escores finais da escala, observa-se que os participantes do G1 apresentaram melhor QVRS do que os do G2 no escore FACT-G total score, o G1 apresentou melhor QVRS do que o G2, enquanto no FACT-H&N Total score e TOI o G2 apresentou resultados ligeiramente melhores, porém sem significância estatística. Quanto ao uso do LIVOX, todos os participantes que apresentaram alguma dificuldade no seu uso tinham mais de 58 anos e se declararam aposentados não ativos (p=0,04). Conclui-se que é importante o oferecimento, tanto no pré quanto no pós operatório, de cuidados que possam avaliar e melhorar a qualidade de vida relacionada à saúde das pessoas com câncer de cabeça e pescoçoThe treatment of head and neck cancer and the communication difficulties resulting from laryngectomy significantly interfere in the quality of life of the affected people, especially regarding the functional, psychological and social aspects. This study aimed to assess the health-related quality of life (HRQoL) of people with head and neck cancer. This paper is an exploratory cross-sectional study with quantitative methodology. The data collection, which occurred between May and September of 2015, was carried out with 100 people with head and neck cancer, who were divided into two groups: G1: laryngectomized people, G2: non- laryngectomized people. To this end, an alternative communication application (LIVOX), installed on a tablet, was used, and the Brazilian Economic Classification Criteria (CCEB) and the Functional Assessment of Cancer Therapy (FAC-H&N) scale were applied. For the data analysis, the Fisher\'s exact test was used, as well as the Kruskal-Wallis test, the analysis of covariance (ANCOVA) and descriptive statistics. The observed results were the prevalence of people of the male sex, with ages between 59 and 74, married, inactive and retired, and with low education and socioeconomic status. The participant subjects of both groups evaluated their global quality of life as generally satisfactory, with the most affected functions being those of emotional and functional well-being. Regarding the scale\'s final scores comparison, it was observed that the G1 participants presented better HRQoL on the FACT-G total score than those of the G2, whereas the G2 presented slightly better results on the FACT-H&N and TOI, although with no statistical significance. As for the use of the LIVOX app, all participants who presented some sort of difficulty when using it were over 58 years old and declared themselves as inactive (p=0,04). It is therefore concluded that the illness and treatment process interferes in the subject\'s life, and that it is important to offer, at both preoperative and post-operative stages, the means for assessing and improving the health- related quality of life of people with head and neck cancer

	Head and neck tumor is frequently encountered clinically, but the list of differential diagnosis of neck lumps is lengthy. Consequently, the major concern of diagnostic procedure is to effectively narrow the possibility, and finally make an accurate diagnosis. Ultrasound-guided core biopsy (USCB) has been well established in many medical fields as the standard tissue sampling procedure, with less harm than open biopsy (OB) and more pathological information than ultrasound-guided fine needle aspiration (USFNA). In addition, using the small-cutting needle, USCB can be easily and safely performed for head and neck lesions. In this review, we present our optimal procedure of applying USCB and review its roles in head and neck, including cervical lymph nodes, thyroid tumors, salivary tumors, pediatric head and neck lesions, cervical infectious diseases, head and neck cancer and aerodigestive tumors. The procedure-related bleeding and tumor seeding are rarely reported even after 7-year follow up in the literature. The head and neck surgeons are competent to take care of any unpredictable complications caused by USCB. According to our experience, USCB can be utilized as a powerful tool in surgeon's hands to explore the possibilities of doing tissue sampling in many areas of head and neck.

	Taper corrosion of the head-neck junction is a potentially significant and devastating problem facing orthopedic surgeons. We present a case of a 53 year old male who presented for routine follow up for a left, large head, metal on metal total hip arthroplasty five years out. The patient was asymptomatic at the visit. X-rays at the time demonstrated a large amount of medial calcar osteolysis. Serum ion levels revealed a mildly increased cobalt and normal chromium level and hip aspiration revealed brownish fluid. At the time of revision surgery, corrosion of the head-neck taper was found with a normal appearing bearing surface leading to the diagnosis of mechanically assisted crevice corrosion of the head-neck taper with medial calcar osteolysis.
