Four hundred nineteen patients and 246 controls were randomly enrolled. Patients were defined as individuals with chronic neck pain, and controls as those with chronic back pain. The two groups were surveyed for cause of chronic pain as well as demographic information. The two groups were compared using an exposure-odds ratio. Forty-five per cent of the patients attributed their pain to a motor vehicle accident. An OR of 4.0 and 2.1 was calculated for men and women, respectively. Based on the results of the present study, it reasonable to infer that a significant proportion of individuals with chronic neck pain in the general population were originally injured in a motor vehicle accident.

    Full Text Available Introduction: Causes of head and neck cancers (HNCs are multifactorial, and few studies have investigated the association between chemical exposure and HNCs. The objective of this study was to investigate associations between HNCs, agricultural occupations, and pesticide exposure. The potential for the accumulation of pesticides in the adipose tissue of patients was also investigated.   Materials and Methods: A structured questionnaire was used to collect information on demographics, occupation, and exposure to pesticides in a hospital-based case-control study. Pesticide residue in the adipose tissue of the neck in both cases and controls was also monitored via gas chromatography–mass spectroscopy.   Results: Thirty-one HNC cases were included in this study as well as 32 gender-, age-, and smoking-matched controls. An agricultural occupation was associated with HNC (odds ratio [OR], 3.26; 95% confidence interval [CI], 1.13–9.43 after controlling for age, sex, and smoking. Pesticide exposure was associated with total HNC cases (OR, 7.45; 95% CI, 1.78–3.07 and larynx cancer (OR, 9.33; 95% CI, 1.65–52.68. A dose-response pattern was observed for HNC cases (P=0.06 and larynx cancer (P=0.01. In tracing the pesticide residue, five chlorinated pesticides, namely dichlorodiphenyltrichloroethane (DDT, dichlorodipheny-ldichloroethane (DDD, dichlorodiphenyldichloroethylene (DDE, dieldrin, and lindane, were identified in the adipose tissue. Chlorinated pesticide detection was significantly associated with HNC (OR, 3.91; 95% CI 0.9–0.16.9.   Conclusion: HNCs were found to be associated with pesticide exposure after controlling for confounders. A high education level was identified as a modifying factor decreasing the risk of HNCs. Further studies with larger number of subjects are recommended to assess these relationships in greater detail.

    A large neck circumference might be an indicator of metabolic syndrome and its components, and for certain patients is more practical as an index than waist circumference. The demarcation value for neck circumference that suggests metabolic syndrome appears to vary by ethnic group. Gestational diabetes mellitus is considered a component of metabolic syndrome in pregnant women. We investigated whether neck circumference in Han Chinese women is associated with gestational diabetes mellitus in early pregnancy, and determined a predictive demarcation value. A nested case-control study was carried out with 255 women aged 18-35 years. Gestational diabetes mellitus was diagnosed according to the criteria of the American Diabetes Association through a 2-h, 75-g oral glucose tolerance test. Of the total population, 41 (16%) women developed gestational diabetes mellitus by 24-28 weeks of gestation. Neck circumference at gestational week 16 positively correlated with pre-pregnancy waist circumference, bodyweight and body mass index, and maternal age (P = 0.029) and hemoglobin A1c at gestational week 24 (P ≤ 0.001). By binary logistic regression, neck circumference was an independent predictor of gestational diabetes mellitus (odds ratio 1.840, 95% confidence interval 1.040-3.254; P = 0.036). According to the receiver operating characteristic curve, for predicting gestational diabetes mellitus the optimal demarcation for neck circumference at gestational week 16 was 35.15 cm. Neck circumference is a viable tool to screen for gestational diabetes mellitus. In this population of pregnant Han Chinese women, a neck circumference of ≥35.15 cm was a predictor of gestational diabetes mellitus. © 2016 The Authors.

    The purpose of this study was to evaluate neck control outcomes after definitive radiochemotherapy without planned neck dissection in node-positive head and neck cancer. We retrospectively reviewed medical records of fifty patients with node-positive head and neck cancer who received definitive radiochemotherapy. Twelve patients subsequently underwent neck dissection for suspicious recurrent or persistent disease. A median dose of 70 Gy (range 60-70.6) was delivered to involved nodes. Response evaluation was performed at a median of 5 weeks after completion of radiotherapy. Neck failure was observed in 11 patients and the 3-year regional control (RC) rate was 77.1%. Neck dissection was performed in 10 of the 11 patients; seven of these cases were successfully salvaged, and the ultimate rate of neck control was 92%. The remaining two patients who received neck dissection had negative pathologic results. On univariate analysis, initial nodal size > 2 cm, a less-than-complete response at the primary site, post-radiotherapy nodal size > 1.5 cm, and post-radiotherapy nodal necrosis were associated with RC. On multivariate analysis, less-than-complete primary site response and post-radiotherapy nodal necrosis were identified as independent prognostic factors for RC. The neck failure rate after definitive radiochemotherapy without planned neck dissection was 22%. Two-thirds of these were successfully salvaged with neck dissection and the ultimate neck control rate was 92%. Our results suggest that planned neck dissection might not be necessary in patients with complete response of primary site, no evidence of residual lesion > 1.5 cm, or no necrotic lymph nodes at the 1-2 months follow-up evaluation after radiotherapy

    Neck pain is associated with several alterations in neck motion and motor control, but most of the findings are based on cross-sectional studies. The aim of this study was to investigate associations between changes in neck motion and motor control, and changes in neck pain and disability in physiotherapy patients during a course of treatment. Prospective cohort study. Subjects with non-specific neck pain (n = 71) participated in this study. Neck flexibility, joint position error (JPE), head steadiness, trajectory movement control and postural sway were recorded before commencement of physiotherapy (baseline), at 2 weeks, and at 2 months. Numerical Rating Scale and Neck Disability Index were used to measure neck pain and disability at the day of testing. To analyze within subjects effects in neck motion and motor control, neck pain, and disability over time we used fixed effects linear regression analysis. Changes in neck motion and motor control occurred primarily within 2 weeks. Reduction in neck pain was associated with increased cervical range of motion in flexion-/extension and increased postural sway when standing with eyes open. Decreased neck disability was associated with some variables for neck flexibility and trajectory movement control. Cervical range of motion in flexion-/extension was the only variable associated with changes in both neck pain and neck disability. This study shows that few of the variables for neck motion and motor control were associated with changes neck pain and disability over a course of 2 months with physiotherapy treatment.

    Neck pain is associated with several alterations in neck motion and motor control. Previous studies have investigated single constructs of neck motor control, while few have applied a comprehensive set of tests to investigate cervical motor control. This comparative cross- sectional study aimed to investigate different motor control constructs in neck pain patients and healthy controls. A total of 166 subjects participated in the study, 91 healthy controls (HC) and 75 neck pain patients (NP) with long-lasting moderate to severe neck pain. Neck flexibility, proprioception, head steadiness, trajectory movement control, and postural sway were assessed using a 3D motion tracking system (Liberty). The different constructs of neck motion and motor control were based on tests used in previous studies. Neck flexibility was lower in NP compared to HC, indicated by reduced cervical ROM and conjunct motion. Movement velocity was slower in NP compared to HC. Tests of head steadiness showed a stiffer movement pattern in NP compared to HC, indicated by lower head angular velocity. NP patients departed less from a predictable trajectory movement pattern (figure of eight) compared to healthy controls, but there was no difference for unpredictable movement patterns (the Fly test). No differences were found for postural sway in standing with eyes open and eyes closed. However, NP patients had significantly larger postural sway when standing on a balance pad. Proprioception did not differ between the groups. Largest effect sizes (ES) were found for neck flexibility (ES range: 0.2-0.8) and head steadiness (ES range: 1.3-2.0). Neck flexibility was the only construct that showed a significant association with current neck pain, while peak velocity was the only variable that showed a significant association with kinesiophobia. NP patients showed an overall stiffer and more rigid neck motor control pattern compared to HC, indicated by lower neck flexibility, slower movement velocity

    The function of the scapula is important in normal neck function and might be disturbed in patients with neck pain. The surrounding muscular system is important for the function of the scapula. To date, it is not clear if patients with idiopathic neck pain show altered activity of these scapulothoracic muscles. Therefore, the objective of this study was to investigate differences in deeper and superficial lying scapulothoracic muscle activity between patients with idiopathic neck pain and healthy controls during arm elevation, and to identify the influence of scapular dyskinesis on muscle activity. Scapular dyskinesis was rated with the yes/no method. The deeper lying (Levator Scapulae, Pectoralis Minor (Pm) and Rhomboid major) and superficial lying (Trapezius and Serratus Anterior) scapulothoracic muscles' activity was investigated with fine-wire and surface EMG, respectively, in 19 female subjects with idiopathic neck pain (age 28.3±10.1years, average duration of neck pain 45.6±36.3months) and 19 female healthy control subjects (age 29.3±11.7years) while performing scaption and towel wall slide. Possible interactions or differences between subject groups, scapular dyskinesis groups or phases of the task were studied with a linear mixed model. Higher Pm activity during the towel wallslide (p=0.024, mean difference 8.8±3.3% MVIC) was shown in patients with idiopathic neck pain in comparison with healthy controls. For the MT, a significant group∗dyskinesis interaction effect was found during scaption which revealed that patients with neck pain and scapular dyskinesis showed lower Middle Trapezius (MT) activity in comparison with healthy controls with scapular dyskinesis (p=0.029, mean difference 5.1±2.2% MVIC). In the presence of idiopathic neck pain, higher Pm activity during the towel wallslide was found. Patients with neck pain and scapular dyskinesis showed lower MT activity in comparison with healthy controls with scapular dyskinesis during scaption

    Impaired neck muscle function leads to disability in individuals with chronic whiplash-associated disorder (WAD), but diagnostic tools are lacking. In this study, deformations and deformation rates were investigated in five dorsal neck muscles during 10 arm elevations by ultrasonography with speckle tracking analyses. Forty individuals with chronic WAD (28 women and 12 men, mean age = 37 y) and 40 healthy controls matched for age and sex were included. The WAD group had higher deformation rates in the multifidus muscle during the first (p muscles for deformation rate (controls: R(2) = 0.24-0.82, WAD: R(2) = 0.05-0.74) and deformation of the deepest muscles (controls: R(2) = 0.61-0.32, WAD: R(2) = 0.15-0.01) were stronger for women in the control group versus women with WAD, indicating there is altered interplay between dorsal neck muscles in chronic WAD.

    Full Text Available Introduction: Deep neck space infections (DNSI are serious diseases that involve several spaces in the neck. The common primary sources of DNSI are dental infections, tonsillar and salivary gland infections, malignancies, and foreign bodies. With widespread use of antibiotics, the prevalence of DNSI has been reduced. Common complications of DNSI include airway obstruction, jugular vein thrombosis, and sepsis. Treatment principally comprises airway management, antibiotic therapy, and surgical intervention. This study was conducted to investigate the age and sex distribution of patients, symptoms, presentation, sites involved, bacteriology, and management and complications of DNSI.   Materials and Methods: This retrospective study was performed from October 2010 to January 2013, and included 76 patients with DNSI. Patients of all age groups and gender were included. All parameters including age, gender, co-morbidities, presentation, site, bacteriology, complications, and required interventions were studied.   Results: In our study, the majority of patients were in the 31–50-year age group. Males accounted for 55.26% of the sample and females for 44.74%, with a male:female ratio of 1.23. Most of the patients were from a rural background. Diabetes was found as a co-morbid condition in 10.52% cases. Neck pain was the most common symptom, identified in 89.47% cases. The most common etiological factor was odontogenic infection (34.21%, followed by tonsillar and pharyngeal infection (27.63%. The most common presentation was Ludwig’s angina (28.94%, followed by peritonsillar abscess and submandibular abscess. In 50% of cases, Streptococcus and Staphylococcus were found in the culture. Surgical intervention was carried out in 89.47% cases. Emergency tracheotomy was required in 5.26% cases.   Conclusion:  DNSI can be life-threatening in diabetic patients, the immunocompromised, and elderly patients, and special attention should therefore be given

    Head and neck sarcomas are exceedingly rare and they include 4% - 10% of all sarcomas and less than 1% of all neoplasm of head and neck. The aim of this study is to evaluate the epidemiological characteristics of head and neck sarcomas of patients in Isfahan, Iran. In this retrospective study, from the 16000 patients whose files were evaluated, the total number of 105 head and neck sarcomas were collected. They were evaluated with due attention to age, gender of the patients and the most common location of the lesion. From the total number of 105 (0.6%) patients with sarcomas, 56 were men (53.33%) and 49 women (46.66%). The most common head and neck sarcomas among this population were Osteosarcoma (32 cases, 30.47%), Chondrosarcoma (14 cases, 13.33%), and Ewing sarcoma (11 cases, 10.47%).The most common soft tissue sarcoma was Rabdomiosarcoma. Mandible was the most common location for these lesions. In this study, the hard tissue sarcomas were more prevalent than soft tissue ones. Hence, special attention should be paid to the patients when being diagnosed.

    People with neck pain display a diminished joint position sense and disturbed postural control, which is thought to be a result of impaired somatosensory afferent activity and/or integration. Afferent processing can be artificially manipulated by vibration and was shown to reduce motor performance in healthy subjects. However, the effect of vibration on sensorimotor function in neck pain patients is scarcely investigated. To assess the effect of neck muscle vibration on joint position sense and postural control in neck pain subjects and healthy controls. Case control study. Thirteen neck pain patients and 10 healthy controls participated in the present study. Cervical joint position sense and dynamic and static postural stability. Short-term, targeted neck muscle vibration with 100 Hz was applied after baseline measurement. Vibration had opposite effects in patients and healthy subjects. Patients showed improved joint position sense (pneck pain. Thus, vibration may be used to counteract sensorimotor impairment of the cervical spine. Potential underlying mechanisms are discussed.

    A case-control study was conducted among residents of Rochester, Minn, to assess the influence of prior therapeutic radiation on the risk of primary hyperparathyroidism. Fifty-one cases of surgically proven primary hyperparathyroidism diagnosed from 1975 through 1983 were each matched by age and gender to two control subjects, with radiation exposure documented through preexisting medical records. The overall odds ratio for any prior therapeutic radiation therapy was 1.9 (95% confidence interval, 0.9 to 4.4) and it was 2.3 (95% confidence interval, 0.9 to 5.7) when limited to those with prior head and neck radiation. Among women, the figures were 2.9 (95% confidence interval, 1.1 to 7.5) for any prior therapeutic radiation and 3.4 (95% confidence interval, 1.2 to 10.2) for head and neck exposure. This study confirms the association between primary hyperparathyroidism and prior therapeutic radiation exposure, at least for women in this population

    The objectives of the feasibility study were to collect and analyse the information necessary to assess the feasibility of a multi-centric study of adult head and neck tumours (including brain tumours) and mobile telephones. Information was obtained on the availability and accessibility of records from companies, the prevalence of mobile telephone use over time and the expected number of tumour cases in the proposed study regions. The conclusion is that it is feasible to develop a study of the relation between mobile telephone use and brain cancer risk. The feasibility of a study of the relation between radiofrequency exposure and cancer risk is, however, unclear at present. It is unknown whether a sufficiently accurate and precise RF exposure gradient can be derived to classify adequately each subject in the proposed study. A study of the relation between mobile telephone use and risk of salivary gland tumours and acoustic neurinomas is probably feasible, but more information is required about the logistic difficulties of ascertaining these cases in the study regions. Two subcommittees have been formed to develop the exposure measurement and epidemiological aspect of the study. (author)

    The use of acupuncture has been suggested for the treatment of acute neck pain caused by stiff neck in China. However, current evidence is insufficient to draw any conclusions about its efficacy. Therefore this pilot study was designed to evaluate the feasibility and efficacy of acupuncture at the Houxi (SI3) acupoint for treatment of acute neck pain. This pilot study will be a two-parallel-group, assessor-blinded, randomised controlled trial. Thirty-six stiff neck participants with acute neck pain will be recruited and randomly divided into two groups in a 1:1 ratio. Participants in the control group will receive massage on the local neck region (5 min each session, three times a day for 3 days). In addition to massage, patients in the treatment group will receive acupuncture (one session a day for 3 days). Measures will be taken at 0, 3 and 15 days. The primary outcome is the Northwick Park Neck Pain Questionnaire (NPQ). The secondary outcome is the Short Form of the McGill Pain Questionnaire (SF-MPQ). The protocol for this pilot randomised clinical trial has undergone ethics scrutiny and been approved by the ethics review boards of the First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine (Permission number: HZYLL201303502). The findings of this study will provide important clinical evidence on the feasibility and efficacy of acupuncture treatment for stiff neck patients with acute neck pain. In addition, it will explore the feasibility of further acupuncture research. ChiCTR-TRC-13003911. Published by the BMJ Publishing Group Limited.

    Concurrent chemoradiotherapy (CCRT) is one of the recent emerging modalities for advanced squamous cell carcinoma of the head and neck (HNSCC). However some of the patients treated by CCRT have residual or recurrent cervical lymph nodes. In these cases, neck dissection is considered to be useful in the point of locolegional control and disease free survival. This study aims to analyze neck control rate by CCRT and usefulness of the neck dissection after CCRT for HNSCC. The medical records of 69 consecutive patients (stage III: 4%, stage IV: 96%) treated with CCRT for SCCHN (hypopharynx: 40, oropharynx: 25, larynx: 4) from 2003 through 2007 were reviewed. Clinical complete response (CR) rates of N1, N2a, N2b, N2c and N3 were 75%, 100%, 71%, 74% and 43% respectively. Among the patients with complete neck response, only 2 patients (5%) had an isolated neck recurrence. Eleven patients underwent surgical neck procedures including 7 planned neck dissections and 4 salvage neck dissections. All the 11 patients with neck dissections had good regional control except 1 case. There were a few minor complications such as wound infection and laryngeal edema. Patients who have a complete clinical regional response to CCRT have a low probability of an isolated recurrence in the neck. Planned and salvage neck dissections can be safely performed and considered to be useful in the point of regional control after intensive CCRT. (author)

    Objective To evaluate if pelvic or hip width predisposed women to developing greater trochanteric pain syndrome (GTPS). Design Prospective case control study. Participants Four groups were included in the study: those gluteal tendon reconstructions (n=31, GTR), those with conservatively managed GTPS (n=29), those with hip osteoarthritis (n=20, OA) and 22 asymptomatic participants (ASC). Methods Anterior-posterior pelvic x-rays were evaluated for femoral neck shaft angle; acetabular index, and width at the lateral acetabulum, and the superior and lateral aspects of the greater trochanter. Body mass index, and waist, hip and greater trochanter girth were measured. Data were analysed using a one-way analysis of variance (ANOVA; posthoc Scheffe analysis), then multivariate analysis. Results The GTR group had a lower femoral neck shaft angle than the other groups (p=0.007). The OR (95% CI) of having a neck shaft angle of less than 134°, relative to the ASC group: GTR=3.33 (1.26 to 8.85); GTPS=1.4 (0.52 to 3.75); OA=0.85 (0.28 to 2.61). The OR of GTR relative to GTPS was 2.4 (1.01 to 5.6). No group difference was found for acetabular or greater trochanter width. Greater trochanter girth produced the only anthropometric group difference (mean (95% CI) in cm) GTR=103.8 (100.3 to 107.3), GTPS=105.9 (100.2 to 111.6), OA=100.3 (97.7 to 103.9), ASC=99.1 (94.7 to 103.5), (ANOVA: p=0.036). Multivariate analysis confirmed adiposity is associated with GTPS. Conclusion A lower neck shaft angle is a risk factor for, and adiposity is associated with, GTPS in women. PMID:22547561

    Head and neck cancers account for an estimated 549,000 global cancer diagnoses each year. While tobacco use, alcohol consumption, and HPV16 infection are considered to be the major risk factors for this disease, occupational risk factors, including exposure to asbestos, have also been described, although dust exposures other than asbestos have been historically understudied. We have investigated the relationship between occupational exposures to five types of dusts, including sawdust, concrete dust, leather dust, metal dust, and chimney soot, and head and neck squamous cell carcinomas (HNSCC) in the greater Boston area. We report findings from a population-based case-control study involving 951 incident HNSCC cases and 1193 controls, frequency matched on age (±3 years), sex, and town/neighborhood of residence. Multivariable logistic regression was used to assess the association between occupational exposure to each type of dust and HNSCC, overall and by primary tumor site. After adjusting for age, sex, race, smoking, alcohol consumption, education, and HPV16 serology, laryngeal carcinoma risk increased for each decade of occupational exposure to sawdust (OR = 1.2, 95% CI: 1.0, 1.3) and metal dust (OR = 1.2, 95% CI: 1.0, 1.4); and HNSCC risk increased for each decade of occupational leather dust exposure (OR = 1.5, 95% CI: 1.2, 1.9). We have provided evidence for an association between occupational sawdust and metal dust and laryngeal squamous cell carcinoma, and leather dust and HNSCC, with increasing risk with longer duration at the exposed occupation. © 2013 The Authors.

    We hypothesized that radiotherapy (RT) would improve both local and regional control with Merkel cell carcinoma of the head and neck. A single-institution institutional review board-approved study was performed including 113 patients with nonmetastatic Merkel cell carcinoma of the head and neck. Postoperative RT was delivered to the primary tumor bed (71.7% cases) ± draining lymphatics (33.3% RT cases). Postoperative local RT was associated with improved local control (3-year actuarial local control 89.4% vs 68.1%; p = .005; Cox hazard ratio [HR] 0.18; 95% confidence interval [CI] = 0.06-0.55; p = .002). Similarly, regional RT was associated with improved regional control (3-year actuarial regional control 95.0% vs 66.7%; p = .008; Cox HR = 0.09; 95% CI = 0.01-0.69; p = .02). Regional RT played an important role for both clinical node-negative patients (3-year regional control 100% vs 44.7%; p = .03) and clinical/pathological node-positive patients (3-year regional control 90.9% vs 55.6%; p = .047). Local RT was beneficial for all patients with Merkel cell carcinoma of the head and neck, whereas regional RT was beneficial for clinical node-negative and clinical/pathological node-positive patients. © 2016 Wiley Periodicals, Inc.

    Low socioeconomic status has been reported to be associated with head and neck cancer risk. However, previous studies have been too small to examine the associations by cancer subsite, age, sex, global region and calendar time and to explain the association in terms of behavioral risk factors. Individual participant data of 23,964 cases with head and neck cancer and 31,954 controls from 31 studies in 27 countries pooled with random effects models. Overall, low education was associated with an increased risk of head and neck cancer (OR = 2.50; 95% CI = 2.02 - 3.09). Overall one-third of the increased risk was not explained by differences in the distribution of cigarette smoking and alcohol behaviors; and it remained elevated among never users of tobacco and nondrinkers (OR = 1.61; 95% CI = 1.13 - 2.31). More of the estimated education effect was not explained by cigarette smoking and alcohol behaviors: in women than in men, in older than younger groups, in the oropharynx than in other sites, in South/Central America than in Europe/North America and was strongest in countries with greater income inequality. Similar findings were observed for the estimated effect of low versus high household income. The lowest levels of income and educational attainment were associated with more than 2-fold increased risk of head and neck cancer, which is not entirely explained by differences in the distributions of behavioral risk factors for these cancers and which varies across cancer sites, sexes, countries and country income inequality levels. © 2014 UICC.

    Although parotid-sparing IMRT decreased the dose distribution of parotid, parotid region recurrence has been reported. Prophylactic irradiation in parotid area would be necessary in patients with high risk of parotid lymph node metastasis (PLNM). This study was to detect the high-risk factors of PLNM in nasopharyngeal carcinoma. This was a 1:2 case-control study. All patients in this study were newly diagnosed NPC with N2-3 classification from January 2005 to December 2012. Cases were 22 sides with ipsilateral PLNM. Controls were 44 patients who were randomly selected from N2-3 disease in database. 20/1096 (1.82 %) NPC patients were found PLNM. Sum of the longest diameter for multiple lymph nodes (SLD) in level II was larger in case group than that in control group (6.0 cm vs. 3.6 cm, p = 0.003). Level II lymph node necrosis, level Va/b involvement, and rare neck areas involvement were more common in case group (p = 0.016, p = 0.034, and p < 0.001, respectively). RPN, level III, and level IV metastases showed no significant difference between the two groups. Multivariate analysis in logistic regression showed that only SLD ≥5 cm in II area (OR = 4.11, p = 0.030) and rare neck areas involvement (OR = 3.95, p = 0.045) were associated with PLNM in NPC patients. PLNM was an uncommon event in NPC patients. SLD ≥5 cm in level II and involvement in rare-neck areas may be potentially high-risk factors for PLNM. Sparing parotid in IMRT was not recommended for NPC patients with high risks of PLNM

    The mechanics, morphometry, and geometry of our joints, segments and muscles are fundamental biomechanical properties intrinsic to human neural control. The goal of our study was to investigate if the biomechanical actions of individual neck muscles predicts their neural control. Specifically, we compared the moment direction & variability produced by electrical stimulation of a neck muscle (biomechanics) to their preferred activation direction & variability (neural control). Subjects sat upright with their head fixed to a 6-axis load cell and their torso restrained. Indwelling wire electrodes were placed into the sternocleidomastoid (SCM), splenius capitis (SPL), and semispinalis capitis (SSC) muscles. The electrically stimulated direction was defined as the moment direction produced when a current (2-19mA) was passed through each muscle's electrodes. Preferred activation direction was defined as the vector sum of the spatial tuning curve built from RMS EMG when subjects produced isometric moments at 7.5% and 15% of their maximum voluntary contraction (MVC) in 26 3D directions. The spatial tuning curves at 15% MVC were well-defined (unimodal, pbiomechanics but, as activation increases, biomechanical constraints in part dictate the activation of synergistic neck muscles.

Materials and methods: Thirty-four male rugby players were divided into forward and back playing positions and randomized within these groups. Seventeen players were randomly assigned to each group. The test group was given a tailored 6-week exercise regime based on their baseline measurements to be performed three times a week in addition to their normal training and playing. The control group trained and played as normal. The outcome measures used were cervical spine range of movement, neck strength, and neck muscle fatigability. Results: There were no clinically relevant statistically significant differences between the two groups. Trends identified between the two groups suggest that a tailored neck exercise program increases neck strength, particularly neck extension, and increases resistance to fatigue, as well as influencing right- and left-sided neck muscle balance. A reduction in range of movement was also demonstrated in the test group. There was a great deal of variability in range of movement and strength within this age group. No previously undiagnosed neck conditions were detected, and there were no adverse events reported. Conclusion: This study has shown that neck strength, range of movement, and susceptibility of the neck muscles to fatigue can be influenced using a focused neck training regime. It forms an important basis for a larger, multicenter study to ensure the neck is given due attention in

    Full Text Available BACKGROUND Fracture neck of femur has high incidence of complications even with treatment, hence it is also termed as unsolved fracture. Factors making treatment difficult are the blood supply to head, which gets cut off and difficulty in achieving reduction. Impacted fractures can be treated conservatively. If the fracture is undisplaced, a conservative approach may be done or multiple cancellous screws can be used. If the patient’s age is less than 60 years, a closed reduction under C-arm control can be tried. If the reduction is possible, then multiple screw fixations can be done. If reduction is not achieved, then open screw reduction and screw fixation can be done. If the patient is above 60 years of age, then it is preferable to excise the head off and replace it with prosthesis. If the hip is normal, then hemiarthroplasty with a unipolar or bipolar prosthesis can be done. If the hip has pre-existing arthritis, then total hip replacement surgery is advisable. A sincere effort has been put to understand the clinical and surgical outcome of fracture neck of femur in elderly. This paper is intended to help the practicing orthopaedicians to understand the various treatment modalities which is commonly used in practice and also the complications which are associated with the pathology. METHODS  The study was done in the Department of Orthopaedics, Travancore Medical College at Kollam.  The study was done from August 2014 to June 2016.  Eighty cases who attended in the Department of Orthopaedics were taken for the study.  Detailed History and Clinical Examination was conducted. INCLUSION CRITERIA  Both traumatic and pathological fractures were taken up for the study.  Individuals who were aged more than 55 years were taken up for the study. EXCLUSION CRITERIA  Aged less than 55 years were not considered.  All the statistical analysis was done using the latest SPSS software 2015 (California. RESULT Fracture neck of femur

    Neck pain is a major health problem in populations worldwide and an economic burden in modern societies due to its high prevalence and costs in terms of health care expenditures and lost productivity. Massage and exercise therapy are widely used management options for neck pain. However, there is a lack of scientific evidence regarding their effectiveness for subacute and long-lasting neck pain. This study protocol describes a randomized controlled trial aiming to determine the effect of massage and/or exercise therapy on subacute and long-lasting neck pain over the course of 1 year. A randomized controlled trial in which at least 600 study participants with subacute or long-lasting nonspecific neck pain will be recruited and randomly allocated to one of four treatment arms: massage therapy (A), exercise therapy (B), exercise therapy plus massage therapy (C) and advice to stay active (D). The study has an E-health approach, and study participants are being recruited through advertising with a mix of traditional and online marketing channels. Web-based self-report questionnaires measure the main outcomes at 7, 12, 26 and 52 weeks after inclusion. The primary outcomes are a clinically important improvement in pain intensity and pain-related disability at follow-up, measured with a modified version of the Chronic Pain Questionnaire (CPQ). The secondary outcomes are global improvement, health-related quality of life (EQ-5D), sick leave, drug consumption and healthcare utilization. Adverse events are measured by questionnaires at return visits to the clinic, and automated text messages (SMSes) survey neck pain intensity and pain-related disability every week over one year. The results of this study will provide clinicians and stakeholders much needed knowledge to plan medical care for subacute and long-lasting neck pain disorders.

    Chronic computer-related neck pain is common among office workers. Studies have proposed neck strengthening exercise as a therapy to pain relieving and function improvement. The aim of this study was to compare the efficacy of different loading resistance trainings and we hypothesized that women with work-related neck pain could benefit more from progressive resistance training for pain and function recovery. A randomized controlled trial was conducted and subjects characterized by monotonous jobs were recruited. One hundred and nine employed women with chronic neck pain were randomly allocated into three groups, namely, progressive resistance training (PRT), fixed resistance training (FRT), and control group (CG). In PRT and FRT, four exercises for neck muscles with an elastic rubber band were performed on regular basis for 6 weeks. The therapeutic effectiveness was then evaluated at pretreatment, 2, 4, and 6 weeks during training period, and 3-month posttreatment. Assessment tools included visual analog scale (VAS), Neck Disability Index (NDI), pressure pain threshold (PPT), and maximal isometric neck strength. The outcomes were significantly better in PRT and FRT than those in CG at 6-week timepoint and 3-month follow-up (p = 0.000), in terms of VAS, NDI, PPT, and neck muscle strength. Besides, there were statistically significant decreases observed in VAS scores of PRT group compared with those in FRT at 4-, 6-week timepoints, and 3-month follow-up (p training was an effective method for pain relieving, mobility improving, pain threshold, and neck muscle strength enhancing in women with chronic computer-related neck pain. Thus, our study provided evidence that women with work-related neck pain might benefit more from PRT, which may have important implications for future clinical practice. The study was qualified and registered in the Chinese Clinical Trial Registry as ChiCTR-TRC-12002723.

    Recently, the use of chemoradiotherapy for preserving organs in the treatment of head and neck cancer is increasing. However, there is controversy about advanced neck node management in post-chemoradiation cases. We retrospectively analyzed our 119 cases of chemoradiotherapy for oropharyngeal and hypopharyngeal cancer to examine the effectiveness and indications of planned neck dissection. Regional control rate and survival rate were superior in the neck dissection group. If the cases did not achieve complete response (CR) in imaging, planned neck dissection improved the regional control rate significantly. We should perform planned neck dissection immediately rather than 'wait and see' for this persistent disease. However, in the cases achieving radiological CR, it is possible to omit planned neck dissection because of the high salvage rate of neck disease. However, in these cases, careful observation is essential. We clarified that the presence of pathologically positive lymph node is a prognostic factor. For evaluating persistent disease of cervical lymph nodes, positron emission tomography (PET)-CT was the most accurate method of imaging. (author)

    Full Text Available Radial head and neck fractures are the most frequently seen elbow fractures. The usual cause of this injury is a fall onto an outstretched hand with a partly flexed elbow. We report here an unusual case of bilateral non-displaced radial neck fractures in a patient who presented with complaints of pain in both elbows following a simple fall. This case highlights the need for a high index of suspicion in the diagnosis of multiple injuries, no matter how `trivial` the mechanism of injury.

    Despite mounting epidemiological evidence suggesting an inverse association between recreational physical activity and cancer risk, evidence associated with head and neck cancer is scant. We conducted a case-control analysis to examine the associations of lifetime physical inactivity with the risk of head and neck squamous cell carcinoma (HNSCC). We utilized data from the Patient Epidemiology Data System at Roswell Park Cancer Institute (RPCI). Participants included 246 patients with HNSCC and 504 cancer-free controls who received medical services at RPCI between 1990 and 1998. Participants were considered physically inactive if they did not participate in any regular, weekly recreational physical activity throughout their lifetime, prior to diagnosis. Multivariate logistic regression models were utilized to estimate odds ratios (OR) and 95% confidence intervals (CI) representing the association between lifetime physical inactivity and HNSCC risk. We observed a significant positive association between recreational physical inactivity and HNSCC risk (OR = 2.73, 95% CI 1.87-3.99, p physical inactivity associates with HNSCC independent of BMI. In addition, physical inactivity may be a modifiable risk factor among never smokers. These data add to the growing body of evidence suggesting that physical inactivity may be an independent risk factor for cancer.

    Although the functional merits of preserving cervical nerves in neck dissection for head and neck cancer have been reported, the oncologic safety has not yet been determined. Therefore, the purpose of this study was to evaluate the safety of cervical nerve preservation. A retrospective chart review was performed on patients with head and neck cancer who had been treated by neck dissection between 2009 and 2014 at Kyoto Medical Center. Management of cervical nerves and clinical results were analyzed. A total of 335 sides of neck dissection had been performed in 222 patients. Cervical nerves were preserved in 175 neck sides and resected in 160 sides. The 5-year overall survival (OS) rate calculated by the Kaplan-Meier method was 71%. The 5-year neck control rate was 95% in cervical nerve preserved sides and 89% in cervical nerve resected sides. Preserving cervical nerves in neck dissection is oncologically safe in selected cases. © 2017 Wiley Periodicals, Inc.

    Background: Cancer is a unique disease characterized by abnormal growth of cells which have the ability to invade the adjacent tissues and sometimes even distant organs. The limited and contrasting evidence regarding the association of ABO blood groups with the different types of head and neck cancers in the Indian population warrants the need for the present study. Aim and Objective: To assess the relative risk of various Head & Neck cancers among different blood groups. Materials and Method: Three hundred sixty two diagnosed cases of different type of head and neck cancers and 400 controls were selected from four hospitals of New Delhi, India. The information regarding the type of head and neck cancer was obtained from the case sheets of the patients regarding their socio demographic profile, dietary history using a structured performa. The information regarding type of cancer (cases only), ABO blood group was collected. Statistical Tests: The data was analysed using the SPSS 19 version. Chi square test and odd ratios were calculated. The level of significance was fixed at 5%. Results: The O blood group was found to be most prevalent followed by B, A and AB among the cases as well as the controls. Oral cancer patients showed maximum number in blood group O followed by B, A and AB. Significant pattern of distribution was seen among the patients of esophageal cancer, laryngeal cancer and salivary gland cancer as well (p= 0.003, p=0.000 p=0.112 respectively. Conclusion: The present study reveals that there is an inherited element in the susceptibility or protection against different types of head and neck cancers. Blood group A was found to be a potential risk factor for the development of oral cancers, esophageal cancers and salivary gland cancers while blood group B was found to be a potential risk factor for laryngeal cancers.

    Full Text Available The objective of this study was to investigate the influence of pain on postural control in women with neck pain and the relationship with possible changes in sensory systems and posture. The neck pain group was composed of women, aged between 20 and 50years, complaining of neck pain for more than three months; the control group was composed of women without complaints of neck pain. For the characterization of the groups, we used anamnesis, neck disability index and Visual Analogue Scale. Postural balance was assessed on force platform. Postural balance with manipulation of the sensory systems was measured by Foam Laser Dynamic Posturography, exposing the individual to six sensory organization tests. Posture was assessed by the Postural Assessment Software. The normality of the variables were verified using Shapiro-Wilk test, Student’s t-test and Mann-Whitney test for comparison between groups, with a significance level of5%. Groups were homogeneous in demographic variables. We observed higher amplitude and displacement velocity of the center of pressure in the neck pain group, showing greater postural balance. There were significant diferences incraniovertebral angle, showing forward head posture in symptomatic women. In dynamics posturography, we observed a difference between the groups: the score obtainedin the six sensory conditions showed that neck pain group presented greater balance impairment. Neck pain and forward head posture have a deleterious effect on postural control in symptomatic women, both in the static posture and dynamic posture.

    Work-related musculoskeletal disorders (MSD) are quite frequent in healthcare workers (HCWs), but data about MSD in home-based healthcare workers (HHWs) are lacking. In this study we describe the prevalence of MSD among Italian HHWs. A case-control study was carried out among 300 random-selected female HCWs, the sample comprising 100 HHWs, 100 HCWs with a low exposure to patient handling (MAPO - Movimentazione e Assistenza Pazienti Ospedalizzati - Movement and Assistance of Hospital Patients index 0-5) and 100 HCWs with high exposure to patient handling (MAPO index ≥ 5.01). As a negative control group, 200 visual display unit workers were also randomly selected. Musculoskeletal disorder cases were collected using a standardized case definition. A multivariate logistic regression analysis was performed comparing the MSD prevalence in the 4 groups. The overall prevalence of MSD was 17% in the reference group and 28.3% for HCWs. HHWs and HCWs with MAPO index ≥ 5.01 had similar prevalence of neck pain (9% and 11%, respectively), whereas lumbosacral pain prevalence was higher in the HHWs group (31%), with similar results in residential HCWs groups (21% in MAPO index 0-5 group and 25% in MAPO index ≥ 5.01 group). HCWs of group MAPO index ≥ 5.01 and HHWs showed the higher prevalence of upper limb complaints, with a prevalence of 20% and 10%, respectively. In multivariate regression analysis, prevalence of MSD complaints was quite similar in HHWs (adjusted odds ratio (ORadj) = 2.335, 95% confidence interval (CI): 1.318-4.138) and in HCWs of the group MAPO ≥ 5.01 (ORadj = 2.729, 95% CI: 1.552-4.797). The prevalence of MSD in the examined HCWs was relatively high, with HHWs appearing as a particularly high-risk group for lumbosacral back pain. In higher exposed HCWs, upper-limb symptoms were particularly frequent, probably reflecting the different tasks required to manage residential and homebased patients. In conclusion, this study reaffirms the high prevalence of

    Neck dissection is a highly important surgical procedure in the treatment of squamous cell carcinoma (SCC) of the head and neck since the control of the nodal disease is highly important in these patients. In this paper, 131 patients (210 necks) treated in our department were analyzed. The most frequent primary lesion site was the oral cavity, followed by larynx, hypopharynx and mesopharynx, and treatment of metastatic nodes was considered important especially in patients with SCC in those regions. As the surgical procedure for neck dissection, (modified) radical neck dissection was chosen for higher N stage cases, although it was also applied to lower N stage cases. Postoperative irradiation was performed for 70% of the patients, and control of the neck was considered good as recurrent neck disease occurred in 8% of the patients, and only 20% of those died of recurrent neck disease. The most common primary site showing cervical recurrence was the oral cavity, and control of neck disease is considered important, especially in patients with SCC of the oral cavity. Patients with ≤number of pN 1 receiving postoperative irradiation, and patients with pN (-) and ≤number of pN 1 without postoperative irradiation showed significantly higher survival rates. Postoperative irradiation should be done for patients with ≥number of pN 2, and follow-up without postoperative treatment should be considered for the cases of ≤number of pN 1. Further consideration of patient selection with regard to the area of dissection and the indication for postoperative irradiation without decreasing the survival rate is needed to further improve the treatment of head and neck SCCs.

    Human papilloma viruses (HPVs) are small DNA viruses that have been identified in periodontal pocket as well as gingival sulcus. High risk HPVs are also associated with a subset of head and neck carcinomas. It is thought that the periodontium could be a reservoir for HPV. 1. Detection of Human Papilloma virus (HPV) in periodontal pocket as well as gingival of patients having localized chronic periodontitis and gingival sulcus of periodontally healthy subjects. 2. Quantitative estimation of E6 and E7 mRNA in subjects showing presence of HPV3. To assess whether periodontal pocket is a reservoir for HPV. This case-control study included 30 subjects with localized chronic Periodontitis (cases) and 30 periodontally healthy subjects (controls). Two samples were taken from cases, one from periodontal pocket and one from gingival sulcus and one sample was taken from controls. Samples were collected in the form of pocket scrapings and gingival sulcus scrapings from cases and controls respectively. These samples were sent in storage media for identification and estimation of E6/E7 mRNA of HPV using in situ hybridization and flow cytometry. Statistical analysis was done by using, mean, percentage and Chi Square test. A statistical package SPSS version 13.0 was used to analyze the data. P value oral cancer, periodontitis and HPV. However prospective studies are required to further explore this link.

    Early in their careers, as an important part of their training to become fighter pilots, pilots undergo centrifuge training in order to learn effective anti-G straining maneuvers (AGSM) and to test their G tolerance. The exposure of pilots, especially early in their careers, to training that could lead to injuries should be avoided. This is a report of four cases of neck pain experienced during G-tolerance training, some of which may have caused ongoing problems for the pilot. Four cases, describing four different injuries experienced during G-tolerance training, are presented, including the history of the incident, radiographic description, and physical examination. Three main questions were identified in regards to the training of fighter pilots in centrifuges: 1) should the seat be positioned to imitate a specific aircraft's seat? 2) should the pilot wear a helmet and a mask? 3) what is the appropriate amount of head support? Based on the four cases reported it is recommended that pilots should be given the best possible conditions concerning neck support and load on the neck and the back for G-tolerance testing. Training the pilot in an anatomical neutral sitting position, without a helmet, and with maximal neck support minimizes head movements in cases of conscious or unconscious loss of muscle control. To test the stability of the neck in a setup similar to the environment where the pilot is going to operate, the pilot should be given the opportunity to prepare himself or herself accordingly in advance.

    A cross-sectional study to investigate regional cerebral blood flow (rCBF) in patients with chronic whiplash syndrome and chronic neck pain patients without previous history of trauma along with a healthy control group. Chronic neck pain is a common disorder and a history of cervical spine injury including whiplash trauma constitute a risk factor for persistent neck pain. The aetiology of the late whiplash syndrome is unknown with no specific diagnostic criteria based on imaging, physiological, or psychological examination. Earlier studies indicate a parieto-occipital hypoperfusion but it is unclear if the hypoperfusion represents a response to chronic pain. The rCBF was monitored in 45 patients with chronic neck pain: 27 cases with chronic whiplash syndrome and 18 age and gender matched cases with non-traumatic chronic neck pain. The rCBF was estimated with single-photon emission computed tomography (SPECT) using technetium-99m hexamethylpropylene amine oxime (HMPAO). The non-traumatic patients displayed rCBF changes in comparison with the whiplash group and the healthy control group. These changes included rCBF decreases in a right temporal region close to hippocampus, and increased rCBF in left insula. The whiplash group displayed no significant differences in rCBF in comparison with the healthy controls. The present study suggests different pain mechanisms in patients with chronic neck pain of non-traumatic origin compared to those with chronic neck pain due to a whiplash trauma.

    We reviewed 42 cases of deep neck abscess drained surgically or treated conservatively between February 2001 and August 2008, based on age, gender, primary focus, main symptom, abscess location, systemic disease, pathogenic bacteria, hospital treatment, hospitalization length, complications and long-term hospitalization. Of the 42, 26 were men and 16 women aged 14 to 80 (central age: 54.5 years). Abscess was caused most by tonsil inflammation (38.1%). Main symptom were sore throat (54.8%) and neck swelling (35.7%). Abscesses were found in the supra- and infrahyoid region in 30 cases and extended to the mediastinum in 2. Of the 42, 14 (33.3%) had hypertension and 11 (26.2%) diabetes mellitus (DM). Inflammation was due to aerobic bacteria (mainly Streptococcus milleri) in 23 cases (54.8%) and to anaerobic bacteria (mainly Peptostreptococcus) in 11 cases (26.2%). Flexible fiberscopic examination was important in evaluating pharyngeal and laryngeal mucosal disorders and enhanced computed tomography was useful in both diagnosis and postoperative observation. Of the 42, 38 required surgical drainage and 4 were cured using needle aspiration and antibiotics. Of the 38 undergoing surgery-tracheostomy was required in 22. Hospitalization for those with tracheostomy and DM was longer than in those without these factors. Complications included 2 cases each of, mediastinal abscess, sepsis, disseminated intravascular coagulation (DIC), acute renal failure, severe pneumonia, upper digestive tract bleeding and swallowing disorder. Early surgical drainage and intravenous antibiotic administration are thus essential for treating deep neck abscesses. (author)

    Radial neck fractures are a common injury in children as a result of a fall on an extended and supinated outstretched hand. We present 2 cases of osteotomy of the neck of the radius performed in 2 children with neglected radial neck fractures. Preoperatively, both patients complained of pain and severely reduced mobility of the elbow. Surgery was performed at 6 weeks and 3 months, respectively, after the initial injury and the 2 children were reviewed at 6 and 16 months follow-up. Osteotomies healed within the usual time and no avascular necrosis of the radial head, proximal radioulnar synostosis, or myositis ossificans were observed. The Mayo Elbow Performance Index Score improved significantly after the operation with the 2 patients rated as excellent. In this small series, we present a novel technique of proximal osteotomy of the radius to correct this deformity in children. Case series, level IV evidence.

    Full Text Available Introduction. Femoral neck fractures in children and adolescents are rare. However, their complications are frequent - avascular necrosis, femoral neck pseudoarthrosis, premature physeal closure with consequent growth disturbance and coxa vara deformity. Case Outline. A 9.5­year­old boy was injured in a car accident, and femoral neck fracture was diagnosed. Prior to admission at our hospital he was surgically treated several times. He was admitted at our hospital eight months following the accident. On the X­ray transcervical pseudoarthrosis of the femoral neck was found, as well as coxa vara deformity and metaphyseal avascular necrosis. He was operated at our hospital; all previously placed ostefixation material was removed, valgus osteotomy of 30 degrees was done as well as additional local osteoplasty using the commercial osteoindactive agent (Osteovit®. Postoperatively, we applied skin traction, bed rest and physical therapy. At the final follow­up, the patient was recovered completely. He is now painless, the legs are of equal length, range of movements in the left hip is full, life activity is normal. The X­ray shows that the femoral neck pseudoarthrosis is fully healed. Conclusion. This case is presented in order to encourage other colleagues to challenge the problematic situation such as this one. Also, we would like to remind them what one should think about and what should be taken into consideration in the primary treatment of femoral neck fractures in children. Valgus femoral osteotomy, as a part of the primary treatment of femoral neck fracture in children (identically as in the adults can prevent the occurrence of femoral neck pseudoarthrosis.

    Head and neck oncologic surgery is a time-consuming specialty that requires extensive resources and manpower. Case mix index (CMI) is used in evaluating the complexity and economic impact of surgeons. Head and neck oncologic surgeons generate significant revenue for hospitals, yet compensation is relatively low. Retrospective review of a tertiary hospital's case mix data for 605 otolaryngology admissions from 2009 to 2011 was performed. CMI comparison for head and neck oncologic surgeons versus general otolaryngology was performed. In an otolaryngology department of 9 surgeons; there was a significant difference (p 1) favoring head and neck oncologic surgeons. Head and neck oncologic surgeons increase the CMI for hospitals and ultimately influence the hospital's reimbursement. There is a need for increased collaboration between hospitals and departments in fostering and furthering their head and neck surgical oncology programs by taking CMI into consideration. © 2013 Wiley Periodicals, Inc.

    Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting. The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as "case-control" and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52-51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69-28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13-0.998) and use of the word "outcome" in the Results section (OR 0.23, 95% CI 0.082-0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure

    Simultaneous fractures of the femoral neck and shaft are not common injuries, though they cannot be considered rare. Herein, we report our experience with a patient with bilateral occurance of this injury. Up to the best of our knowkedge this is the first case reported in literature in which correct diagnosis was made initially. Both femurs were fixed using broad 4.5 mm dynamic compression plate and both necks were fixed using 6.5 mm cannulated screws. Femur fixation on one side was converted to retrograde nailing because of plate failure. Both neck fractures healed uneventfully. In spite of rarity of concomitant fractures of femoral neck and shaft, this injury must be approached carefully demanding especial attention and careful device selection.

    Purpose: The objective of this study was to determine regional control of local regional advanced head and neck squamous cell carcinoma (HNSCC) treated with intensity-modulated radiotherapy (IMRT), along with the role and selection criteria for neck dissection after IMRT. Methods and Materials: A total of 90 patients with stage N2A or greater HNSCC were treated with definitive IMRT from December 1999 to July 2005. Three clinical target volumes were defined and were treated to 70 to 74 Gy, 60 Gy, and 54 Gy, respectively. Neck dissection was performed for selected patients after IMRT. Selection criteria evolved during this period with emphasis on post-IMRT [ 18 F] fluorodeoxyglucose positron emission tomography in recent years. Results: Median follow-up for all patients was 29 months (range, 0.2-74 months). All living patients were followed at least 9 months after completing treatment. Thirteen patients underwent neck dissection after IMRT because of residual lymphadenopathy. Of these, 6 contained residual viable tumor. Three patients with persistent adenopathy did not undergo neck dissection: 2 refused and 1 had lung metastasis. Among the remaining 74 patients who were observed without neck dissection, there was only 1 case of regional failure. Among all 90 patients in this study, the 3-year local and regional control was 96.3% and 95.4%, respectively. Conclusions: Appropriately delivered IMRT has excellent dose coverage for cervical lymph nodes. A high radiation dose can be safely delivered to the abnormal lymph nodes. There is a high complete response rate. Routine planned neck dissection for patients with N2A and higher stage after IMRT is not necessary. Post-IMRT [ 18 F] fluorodeoxyglucose positron emission tomography is a useful tool in selecting patients appropriate for neck dissection

    Bladder neck preservation (BNP) during radical prostatectomy (RP) has been proposed as a method to improve early recovery of urinary continence after radical prostatectomy. However, there is concern over a possible increase in the risk of positive surgical margins and prostate cancer recurrence rate. A recent systematic review and meta-analysis reported improved early recovery and overall long-term urinary continence without compromising oncologic control. The aim of our study was to perform a critical review of the literature to assess the impact on bladder neck and base margins after bladder neck sparing radical prostatectomy. We carried out a systematic review of the literature using Pubmed, Scopus and Cochrane library databases in May 2017 using medical subject headings and free-text protocol according to PRISMA guidelines. We used the following search terms: bladder neck preservation, prostate cancer, radical prostatectomy and surgical margins. Studies focusing on positive surgical margins (PSM) in bladder neck sparing RP pertinent to the objective of this review were included. Overall, we found 15 relevant studies reporting overall and site-specific positive surgical margins rate after bladder neck sparing radical prostatectomy. This included two RCTs, seven prospective comparative studies, two retrospective comparative studies and four case series. All studies were published between 1993 and 2015 with sample sizes ranging between 50 and 1067. Surgical approaches included open, laparoscopic and robot-assisted radical prostatectomy. The overall and base-specific PSM rates ranged between 7-36% and 0-16.3%, respectively. Mean base PSM was 4.9% in those patients where bladder neck sparing was performed, but only 1.85% in those without sparing. Bladder neck preservation during radical prostatectomy may increase base-positive margins. Further studies are needed to better investigate the impact of this technique on oncological outcomes. A future paradigm could

Two samples were taken from cases, one from periodontal pocket and one from gingival sulcus and one sample was taken from controls. Methods and Materials: Samples were collected in the form of pocket scrapings and gingival sulcus scrapings from cases and controls respectively. These samples were sent in storage media for identification and estimation of E6/E7 mRNA of HPV using in situ hybridization and flow cytometry. Statistical analysis: Statistical analysis was done by using, mean, percentage and Chi Square test. A statistical package SPSS version 13.0 was used to analyze the data. P value < 0.05 was considered as statistically significant. Results: pocket samples as well as sulcus samples for both cases and controls were found to contain HPV E6/E7 mRNAInterpretation and Conclusion: Presence of HPV E6/E7 mRNA in periodontium supports the hypothesis that periodontal tissues serve as a reservoir for latent HPV and there may be a synergy between oral cancer, periodontitis and HPV. However prospective studies are required to further explore this link.

    Medical records of 222 patients with neck nodes metastases from squamous cell carcinoma of supraglottic larynx, tonsil and base of tongue were analyzed. All cases were treated with definitive irradiation. 110 patients were treated with orthovoltage technique with total doses of 5000-6000 rads, 150-10 rads per fraction; 112 patients with Co-60 with total doses 6000-7000 rads, 180-230 rads per fraction. Local-regional control was achieved in 28% of cases. Failures in the neck nodes with primary tumor controlled, were recorded in 10% of patients. Failures in a primary tumor alone were observed in 26% of patients, in primary tumor and neck nodes in 36%. Radiocurability of primary tumor and involved neck nodes was similar. In cases with primary tumor controlled, the probability of eradication of neck nodes metastases is high, even in N3 stage patients. Residual neck nodes palpable 1 to 3 months after irradiation were unfavorable prognostic factor indicated 50% risk of neck recurrence. In patients with complete regression of primary and nodal disease, failure in neck nodes was recorded in 5% of cases. The role of surgery following irradiation in patients with cervical nodes metastases is discussed. (author)

The biodistribution studies showed that, in all three cases evaluated, BPA delivered absolute boron values to tumor in the range that proved therapeutically useful in the experimental model of SCC. BPA-BNCT studies showed no radiotoxic effects, partial tumor control in terms of impaired growth and partial necrosis, an improvement in clinical condition and prolonged survival beyond the terminal condition of the feline patients at the time of recruitment.

    Full Text Available Introduction: Pyolaryngocele is a very rare and serious complication of laryngocele. It can present as deep neck space infection and mislead the diagnosis. Our aim is to bring this unusual entity to the attention of surgeons and describe its clinical features. Case Report: We report a case of a 45-year-old male patient with a five-week history of neck swelling, dysphonia, dyspnea and odynophagia. An urgent CT scan showed a mixed pyolaryngocele. The management consisted of a high dose antibiotic and an excision of the residual laryngocele via an external approach. Conclusion: A pyolaryngocele is an unusual complication of laryngocele, which becomes secondarily infected, causing many symptoms. Removing the laryngocele is still the best treatment option to prevent this complication and recurrence.

    Previous studies have identified sensorimotor disturbances and greater fatigability of neck muscles in patients with neck pain. The purpose of this study was to investigate the effect of neck pain and neck flexor fatigue on standing balance following postural perturbations. Twenty patients with chronic neck pain (CNP) (24.7±3.6 year-old) and 20 age-matched asymptomatic subjects (22.1±2.2 year-old) were recruited. Subjects stood barefoot on a force plate and experienced backward perturbations before and after neck flexor fatigue. Center of pressure, electromyography of cervical and lumbar muscles, and head/trunk accelerations were recorded. Two-way ANOVA (pain×fatigue) was used for statistical analysis. CNP group showed larger body sway during quiet standing but not during perturbed standing compared with asymptomatic adults. In both groups, neck flexor fatigue resulted in greater body sway during the quiet standing but smaller body sway during perturbed standing, increased neck muscle activations and decreased lumbar muscle activations, as well as increased time to maximal head acceleration. Disturbed balance control was observed in CNP patients during the quiet standing. However, a rigid strategy was used to minimize the postural sway and to protect the head against backward perturbations in both CNP and asymptomatic young adults after neck flexor fatigue. The results facilitate the understanding of how the subjects with chronic neck pain and with neck muscle fatigue deal with the challenging condition. Further studies are needed to verify if such phenomenon could be changed after the intervention of specific flexor muscle retraining and balance control exercises. Copyright © 2015 Elsevier B.V.

    Although cervical pain is widespread, most victims are only mildly and occasionally affected. A minority, however, suffer chronic pain and/or functional impairments. Although there is abundant literature regarding nontraumatic neck pain, little focuses on diagnostic criteria. During the last decade, research on neck pain has been designed to evaluate underlying pathophysiological mechanisms, without noteworthy success. Independent researchers have investigated postural balance and cervicocephalic kinesthetic sensibility among patients with chronic neck pain, and have (in most cases) concluded the source of the problem is a reduced ability in the neck's proprioceptive system. Here, we investigated cervicocephalic kinesthetic sensibility and postural balance among patients with nontraumatic chronic neck pain. Ours was a two-group, observational pilot study of patients with complaints of continuous neck pain during the 3 months prior to recruitment. Thirteen patients with chronic neck pain of nontraumatic origin were recruited from an institutional outpatient clinic. Sixteen healthy persons were recruited as a control group. Cervicocephalic kinesthetic sensibility was assessed by exploring head repositioning accuracy and postural balance was measured with computerized static posturography. Parameters of cervicocephalic kinesthetic sensibility were not reduced. However, in one of six test movements (flexion), global repositioning errors were significantly larger in the experimental group than in the control group (p < .05). Measurements did not demonstrate any general impaired postural balance, and varied substantially among participants in both groups. In patients with nontraumatic chronic neck pain, we found statistically significant global repositioning errors in only one of six test movements. In this cohort, we found no evidence of impaired postural balance.Head repositioning accuracy and computerized static posturography are imperfect measures of functional

    The variation in treatment portals for elective radiotherapy of the neck, and the three-dimensional dosimetric consequences of this variation was assessed. Therefore, 16 experienced radiation oncologists from all major head and neck cooperative groups in the Netherlands (n=11) were asked to define RT-portals on a lateral and/or AP simulation film, for (routine) elective neck irradiation for a T2 tumor of the mobile tongue and a T3 tumor of the supraglottic larynx. Treatment portals were compared and evaluated using a three-dimensional treatment planning system and CT data with contoured critical structures and target volume. The CT-defined clinical target volume was mutually agreed upon by ENT-surgeons and radiation oncologists. Large differences were seen in treated volume (a factor of five). In addition, due to the variation in the cranial boundary of the RT-portals, the estimated NTCP varied considerably (0-50%). Moreover, several of the RT-portals did not adequately cover the CT-defined target volume. Even amongst experienced head and neck radiation oncologists, little agreement was observed with respect to treatment technique and size of the treatment portals in case of elective neck irradiation. This results in a considerable variation in treated volume. As a consequence, a large difference exists in the anticipated probability of normal tissue complication, and possibly in tumor control probability. Therefore, a definition of target volume and, consequently, a standardization of elective neck portals in mandatory. This is even more important if the primary tumor and clinically node-negative neck are to be treated by 3D conformal RT using multiple CT-slices for target delineation and positioning of BEV blocks in order to spare the normal tissue function with maximum tumor control probability.

    Appropriate supportive care is essential for intensive chemoradiation therapy (CRT), and pain management is an important supportive care for CRT for head and neck cancer. We developed an opioid-based pain control program for head and neck cancer patients undergoing CRT, and assessed its efficacy and safety. 110 head and neck cancer patients undergoing platinum-based concomitant CRT were enrolled from 10 cancer centers or university hospitals. Their pain caused by CRT was managed with a four-step opioid-based pain control program, and adverse events and usage of opioid were analyzed. 101 suitable cases of 110 patients were analyzed. 53% of cases suffered grade 3-4 mucositis. The rate of completion of radiotherapy was 99% and the rate of unplanned breaks in radiotherapy was 13%. The usage rate of opioid was 83% and the rate of compliance with the pain control program was 92%. The median maximum quantity of morphine used per day was 35 mg. No patient had to stop the opioid program or radiotherapy due to adverse effects of opioids. An opioid-based pain control program for head and neck cancer patients undergoing CRT achieves a high completion rate of radiation. (author)

  13. Change in neck circumference after shoulder arthroscopy: An observational study

    Full Text Available Background and Aims: Shoulder arthroscopy requires fluid irrigation, which causes soft-tissue oedema around chest, neck, and arm intraoperatively, leading to postoperative airway complications. We decided to study the incidence of increase in the neck circumference in shoulder arthroscopy and its effects on the airway. Methods: We studied 32 cases of shoulder arthroscopies over a period of 1-year, performed under general anaesthesia with interscalene block. The neck circumference of patients before and after the procedure was measured along with other parameters. The endotracheal tube cuff was deflated at the end of surgery to determine air leak around the tube. The negative leak test suggested airway oedema. Results: Thirty out of 32 patients showed positive air leak test. The average change in neck circumference was 1.17 ± 1.16 cm and all could be extubated uneventfully. Two showed negative leak test with an increase in neck circumference by 4.5 and 6.4 cm and were not extubated. Multiple regression analysis for risk factors showed intraoperative hypertension as a single predictor for an increase in neck circumference. Conclusion: Change in the neck circumference beyond 4 cm may suggest airway compromise and below 4 cm, airway compromise is unlikely even in the presence of extensive soft-tissue oedema around the shoulder, upper arm and chest.

    Purpose/Objective: Radiation-induced xerostomia is a frequent cause of morbidity in head and neck cancer patients. To minimize this complication unilateral techniques (UT) designed to treat the primary tumor and ipsilateral neck have been used for many years in selected cases at our institution. Although such techniques exclude the contralateral parotid from the high dose target volume, they also leave the contralateral neck nodes untreated. The purpose of the study was to evaluate the risk of failure in the opposite neck. Materials and Methods: We identified 229 patients treated with UT from a series of 641 cases with carcinoma of the tonsillar region treated with curative intent between 1970 and 1991. Detailed documentation of the tumor, the radiation dosimetry, the sites of failure, and outcome including local, regional, and distant failure, and late complications, were performed. Actuarial 5-year plots were used to calculate local control, regional control, and survival rates. Results: Median age was 61 years (74 females/155 males); median follow-up 8 years (range 6 months to 21 years). AJCC (1992) T categories were T1:73, T2:120, T3:30, T4:6. The N category distribution was: N0:136, N1:53, N2a:29, N2b:8, and N3:8 cases. Base of tongue and palate were involved in 49 and 82 cases respectively. Irradiation techniques consisted of ipsilateral wedge pairs with Cobalt of 6MV photons in 210 cases (92%), while the remainder were electrons with or without photons. Customized compensators were used in the majority of cases in addition to the use of wedge filters. 75% received 50 Gy in 4 weeks, 10% received 60 Gy in 6 weeks, while the remainder received other doses intended to be curative. A radioactive implant was also used in 20 patients. The 5-year actuarial rates were as follows: overall local control: 76%, regional node control: 80%; cause specific survival: 80%. A total of 7 patients manifested regional disease in the opposite neck (crude rate of 3% or 7 of 229

    The objective of this population-based cohort study was to investigate the association between a lifetime history of neck injury from a motor vehicle collision and the development of troublesome neck pain. The current evidence suggests that individuals with a history of neck injury in a traffic collision are more likely to experience future neck pain. However, these results may suffer from residual confounding. Therefore, there is a need to test this association in a large population-based cohort with adequate control of known confounders. We formed a cohort of 919 randomly sampled Saskatchewan adults with no or mild neck pain in September 1995. At baseline, participants were asked if they ever injured their neck in a motor vehicle collision. Six and twelve months later, we asked about the presence of troublesome neck pain (grade II–IV) on the chronic pain grade questionnaire. Multivariable Cox regression was used to estimate the association between a lifetime history of neck injury in a motor vehicle collision and the onset of troublesome neck pain while controlling for known confounders. The follow-up rate was 73.5% (676/919) at 6 months and 63.1% (580/919) at 1 year. We found a positive association between a history of neck injury in a motor vehicle collision and the onset of troublesome neck pain after controlling for bodily pain and body mass index (adjusted HRR = 2.14; 95% CI 1.12–4.10). Our analysis suggests that a history of neck injury in a motor vehicle collision is a risk factor for developing future troublesome neck pain. The consequences of a neck injury in a motor vehicle collision can have long lasting effects and predispose individuals to experience recurrent episodes of neck pain. PMID:20213298

    Purpose: Minimal literature exists with 10-year data on neck control in advanced head and neck cancer. The purpose of this study is to determine long-term regional control for base of tongue carcinoma patients treated with primary radiation therapy plus neck dissection. Methods and Materials: Between 1981-1996, primary radiation therapy was used to treat 68 patients with squamous cell carcinoma of the base of tongue. Neck dissection was added for those who presented with palpable lymph node metastases. The T-stage distribution was T1, 17; T2, 32; T3, 17; and T4, 2. The N-stage distribution was N0, 10; N1, 24; N2a, 6; N2b, 11, N2c, 8; N3, 7; and Nx, 2. Ages ranged from 35 to 77 (median 55 years) among the 59 males and nine females. Therapy generally consisted of initial external beam irradiation to the primary site (54 Gy) and neck (50 Gy). Clinically positive necks were boosted to 60 Gy with external beam irradiation. Three weeks later, the base of tongue was boosted with an Ir-192 interstitial implant (20-30 Gy). A neck dissection was done at the same anesthesia for those who presented with clinically positive necks, even if a complete clinical neck response was achieved with external beam irradiation. Neoadjuvant cisplatin-based chemotherapy was administered to nine patients who would have required a total laryngectomy if their primary tumors had been surgically managed. The median follow-up was 36 months with a range from 1 to 151 months. Eleven patients were followed for over 8 years. No patients were lost to follow-up. Results: Actuarial 5- and 10-year neck control was 96% overall, 86% after radiation alone, and 100% after radiation plus neck dissection. Pathologically negative neck specimens were observed in 70% of necks dissected after external beam irradiation. The remaining 30% of dissected necks were pathologically positive. These specimens contained multiple positive nodes in 83% despite a 56% overall complete clinical neck response rate to irradiation

    Loss of Y-chromosome has been correlated with older age in males. Furthermore, current evidence indicates that Y-chromosome loss also occurs in several human tumors, including head and neck carcinomas. However, the association between Y nullisomy and the occurrence of neoplasias in elderly men has not been well established. In the present study, the association between Y-chromosome loss and head and neck carcinomas was evaluated by comparison to cells from peripheral blood lymphocytes and normal mucosa of cancer-free individuals matched for age using dual-color fluorescence in situ hybridization. Twenty-one patients ranging in age from 28 to 68 years were divided into five-year groups for comparison with 16 cancer-free individuals matched for age. The medical records of all patients were examined to obtain clinical and histopathological data. None of the patients had undergone radiotherapy or chemotherapy before surgery. In all groups, the frequency of Y-chromosome loss was higher among patients than among normal reference subjects (P < 0.0001) and was not age-dependent. These data suggest that Y-chromosome loss is a tumor-specific alteration not associated with advanced age in head and neck carcinomas.

    The authors discuss the case of radiation-induced skin cancer of the neck in a 76-year-old woman who had undergone irradiation of tubercular lymphadenitis of the cervix while in her low teens. Some fifty years later, a squamous cell carcinoma developed in the irradiated region and in due course deeply invaded the sternocleidomastoidous muscle. Thus, a radical neck dissection was performed and the tumor and the lymph tissue removed en bloc, after which reconstruction was accomplished by using a latissimus dorsi musculocutaneous flap. With regard to the lessons learned from treating this case, three points are considered important and are listed below. When treating radiation-induced skin cancer patients, the head and neck regions should be examined in detail for the presence of other tumors. The excision of the skin surrounding the tumor should be as wide as possible, so as to remove skin that may have been also over-subjected to irradiation. The remaining skin surrounding the defect left by the excision is atrophic and thin. (author)

    Patients with chronic neck pain show also respiratory dysfunctions. To investigate the effects of respiratory muscle endurance training (RMET) on chronic neck pain. In this pilot study (single-subject design: 3 baseline measurements, 4 measurements during RMET), 15 neck patients (49.3 ± 13.7 years; 13 females) conducted 20 sessions of home-based RMET using a SpiroTiger® (normocapnic hyperpnoea). Maximal voluntary ventilation (MVV), maximal inspiratory (Pimax) and expiratory (Pemax) pressure were measured before and after RMET. Neck flexor endurance, cervical and thoracic mobility, forward head posture, chest wall expansion and self-assessed neck disability [Neck Disability Index (NDI), Bournemouth questionnaire] were weekly assessed. Repeated measure ANOVA (Bonferroni correction) compared the first and last baseline and the last measurement after RMET. RMET significantly increased MVV (p= 0.025), Pimax (p= 0.001) and Pemax (pneck pain. The underlying mechanisms, including blood gas analyses, need further investigation in a randomized controlled study.

    The relationship between whiplash trauma and chronic orofacial pain is unclear, especially with regard to the time elapsed from trauma to development of orofacial pain. The aim was to analyze prevalence of jaw pain and disability, as well as the relationship between pain and disability in the jaw and neck regions in the early nonchronic stage after whiplash trauma. In this case-control study, 70 individuals (40 women, 30 men, mean age 35.5 y) who visited an emergency department with neck pain following a car accident were examined within 3 wk of trauma (group 1) and compared with 70 individuals (42 women, 28 men, mean age 33.8 y), who declined to attend a clinical examination but agreed to fill in questionnaires (group 2). The 2 case groups were compared with a matched control group of 70 individuals (42 women, 28 men, mean age 37.6 y) without a history of neck trauma. All participants completed questionnaires regarding jaw pain and dysfunction, rating pain intensity in jaw and neck regions on the Numerical Rating Scale, the Neck Disability Index, and Jaw Disability Checklist. Compared with controls, individuals with a recent whiplash trauma reported more jaw pain and dysfunction. Furthermore, there was a moderate positive correlation between jaw and neck pain ratings for group 1 (r = 0.61, P whiplash trauma report more jaw pain and disability compared with controls without a history of neck trauma. Furthermore, the correlation between jaw and neck pain intensity implies that intensity of neck pain in the acute stage after whiplash trauma might be a possible risk factor also for development of chronic orofacial pain. © International & American Associations for Dental Research 2016.

    Although unilateral posterior neck pain (UPNP) is more prevalent than central neck pain, little is known about how UPNP affects neck motion and the muscle activation pattern during prone neck extension. To investigate whether deviation in neck motion and asymmetry of activation of the bilateral cervical paraspinal muscles occur during prone neck extension in subjects with UPNP compared to subjects without UPNP. This study recruited 20 subjects with UPNP and 20 age- and sex-matched control subjects without such pain. Neck motion and muscle onset time during prone neck extension were measured using a three-dimensional motion-analysis system and surface electromyography. The deviation during prone neck extension was greater in the UPNP group than in the controls (p cervical extensor muscle activation in the UPNP group was significantly delayed on the painful side during prone neck extension (p cervical extensors, triggering a need for specific evaluation and exercises in the management of patients with UPNP.

    Study Design Controlled laboratory study, case-control design. Objective To evaluate spine kinematics and gait characteristics in people with nonspecific chronic neck pain. Background People with chronic neck pain present with a number of sensorimotor and biomechanical alterations, yet little is known about the influence of neck pain on gait and motions of the spine during gait. Methods People with chronic nonspecific neck pain and age- and sex-matched asymptomatic controls walked on a treadmill at 3 different speeds (self-selected, 3 km/h, and 5 km/h), either with their head in a neutral position or rotated 30°. Tridimensional motion capture was employed to quantify body kinematics. Neck and trunk rotations were derived from the difference between the transverse plane component of the head and thorax and thorax and pelvis angles to provide an indication of neck and trunk rotation during gait. Results Overall, the patient group showed shorter stride length compared to the control group (Pneck pain showed smaller trunk rotations (Pneck pain walk with reduced trunk rotation, especially when challenged by walking with their head positioned in rotation. Reduced rotation of the trunk during gait may have long-term consequences on spinal health. J Orthop Sports Phys Ther 2017;47(4):268-277. Epub 3 Feb 2017. doi:10.2519/jospt.2017.6768.

    We speculated that a systematic program to manage radiation dermatitis might decrease the incidence of severe or fatal cases in head and neck cancer patients receiving radiotherapy. Here, we conducted a prospective phase II study to clarify the clinical benefit of a Dermatitis Control Program (DeCoP) that did not use corticosteroids. Head and neck cancer patients scheduled to receive definitive or postoperative radiotherapy were enrolled. Radiation dermatitis was managed with a DeCoP consisting of a three-step ladder: gentle washing; gentle washing and moistening of the wound-healing environment; prevention against infection, gentle washing and moistening of the wound-healing environment. The primary endpoint was the incidence of grade 4 dermatitis. A total of 113 patients were registered between January 2009 and February 2010. Eighty patients received radiotherapy as an initial approach, while the remaining 33 received radiotherapy postoperatively. Grade 3 and 4 dermatitis events occurred in 11 (9.7%) and 0 (0%, 95% confidence interval 0-3.2%) patients, respectively. Median radiation dose at the onset of grade 2 dermatitis was 61.5 Gy (range 36-70 Gy) and median period between onset and recovery was 14 days (range 1-46 days). The Dermatitis Control Program has promising clinical potential. Radiation dermatitis might be manageable if gentle washing and moistening of the wound-healing environment is done. (author)

    (1) To identify reported tests used to assess sensorimotor control in individuals with idiopathic neck pain and (2) to investigate whether these tests can quantify differences between individuals with idiopathic neck pain and healthy individuals. Allied and Complementary Medicine Database, CINAHL, Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Physiotherapy Evidence Database, Scopus, and SPORTDiscus. Studies reporting sensorimotor outcomes in individuals with idiopathic neck pain or healthy individuals were identified. There were 1,677 records screened independently by 2 researchers for eligibility: 43 studies were included in the review, with 30 of these studies included in the meta-analysis. Methodologic quality was determined using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Data were extracted using a standardized extraction table. Sensorimotor control was most commonly assessed by joint position error and postural sway. Pooled means for joint position error after cervical rotation in individuals with neck pain (range, 2.2°-9.8°) differed significantly (P=.04) compared with healthy individuals (range, 1.66°-5.1°). Postural sway with eyes open ranged from 4.85 to 10.5cm 2 (neck pain) and 3.5 to 6.6cm 2 (healthy) (P=.16), and postural sway with eyes closed ranged from 2.51 to 16.6cm 2 (neck pain) and 2.74 to 10.9cm 2 (healthy) (P=.30). Individual studies, but not meta-analysis, demonstrated differences between neck pain and healthy groups for postural sway. Other test conditions and other tests were not sufficiently investigated to enable pooling of data. The findings from this review suggest sensorimotor control testing may be clinically useful in individuals with idiopathic neck pain. However, results should be interpreted with caution because clinical differences were small; therefore, further cross-sectional research with larger samples is needed to determine the magnitude of the relation between

    Although active tobacco smoking has been considered a major risk factor for head and neck cancer, few studies have evaluated environmental tobacco smoke (ETS) and its interaction with mutagen sensitivity on the risk of head and neck cancer. We investigated the relationship between ETS and head and neck cancer in a case-control study of 173 previously untreated cases with pathologically confirmed diagnoses of squamous cell carcinoma of the head and neck and 176 cancer-free controls at Memorial Sloan-Kettering Cancer Center between 1992 and 1994. A structured questionnaire was used to collect ETS exposure and other covariates including a history of active tobacco smoking and alcohol use. ETS measures include a history of ETS exposure at home and at workplace. The associations between passive smoking and head and neck cancer were analyzed by Mantel-Haenszel methods and logistic regression models. Additive and multiplicative models were used to evaluate effect modifications between ETS and mutagen sensitivity. The crude odds ratio (OR) for ETS exposure was 2.8 [95% confidence intervals (CI), 1.3-6.0]. Controlling for age, sex, race, education, alcohol consumption, pack-years of cigarette smoking, and marijuana use, the risk of squamous cell carcinoma of the head and neck was increased with ETS (adjusted OR, 2.4; 95% CI, 0.9-6.8). Dose-response relationships were observed for the degree of ETS exposure; the adjusted ORs were 2.1 (95% CI, 0.7-6.1) for those with moderate exposure and 3.6 (95% CI, 1.1-11.5) for individuals with heavy exposure (P for trend = 0.025), in comparison with those who never had ETS exposures. These associations and the dose-response relationships were still present when the analysis was restricted to nonactive smoking cases and controls (crude OR, 2.2; 95% CI, 0.6-8.4). Crude odds ratios were 1.8 for those with moderate ETS exposure and 4.3 for individuals with heavy ETS exposure among nonsmoking cases and controls (P for trend = 0.008). More

    To investigate the effectiveness of a neck strengthening program on the isometric neck strength profile of male rugby union players. Controlled laboratory study. Professional rugby union club. Fifteen professional and 10 semiprofessional rugby union players. The 15 professional players undertook a 5-week neck strengthening intervention, which was performed twice per week, whereas the 10 semiprofessional players acted as the control group. Isometric strength of the neck musculature was tested using a hand-held dynamometer, for flexion (F), extension (E), left-side flexion (LSF), and right-side flexion (RSF). Preintervention and postintervention evaluations were undertaken. No significant between-group differences in isometric neck strength were noted preintervention. A significant main effect for time was observed (P isometric neck strength in all planes after the 5-week intervention (F preintervention = 334.45 ± 39.31 N vs F postintervention 396.05 ± 75.55 N; E preintervention = 606.19 ± 97.34 vs E postintervention = 733.88 ± 127.16 N; LSF preintervention = 555.56 ± 88.34 N vs LSF postintervention = 657.14 ± 122.99 N; RSF preintervention = 570.00 ± 106.53 N vs RSF postintervention = 668.00 ± 142.18 N). No significant improvement in neck strength was observed for control group participants. The results of the present study indicate that a 5-week neck strengthening program improves isometric neck strength in rugby union players, which may have implications for injury prevention, screening, and rehabilitation. The strengthening program described in the present study may facilitate rehabilitation specialists in the development of neck injury prevention, screening, and rehabilitation protocols.

    Neck pain in adults is common and a leading cause of physical disability. Recently, a guideline was developed for the management of non-specific neck pain (NSNP) with an aim to improve the quality of the delivery of chiropractic care. One key guideline recommendation is to undertake multimodal care for patients with NSNP. The aim of this pilot study is to determine the feasibility of implementing a multifaceted knowledge translation intervention by promoting the use of multimodal care by chiropractors managing patients with NSNP. The design is a cluster-randomized controlled pilot and feasibility trial. Chiropractors in private practice in Canada will be approached to participate in the study. Thirty consenting chiropractors will be randomized to receive either a theory-based educational intervention in the experimental group or simply a printed copy of the guideline in the control group. Each chiropractor will recruit five neck pain patients (a total of 150 patients) into the study. Development of the multifaceted intervention was informed by the results of a related qualitative study based on the Theoretical Domains Framework and consists of a series of three webinars, two online case scenarios, a self-management video on Brief Action Planning, and a printed copy of the practice guideline. Primary feasibility outcomes for both chiropractors and patients include rates of (1) recruitment, (2) retention, and (3) adherence to the intervention. A checklist of proxy measures embedded within patient encounter forms will be used to assess chiropractors' compliance with guideline recommendations (e.g. exercise and self-care prescriptions) at study onset and at 3 months. Secondary outcomes include scores of behavioural constructs (level of knowledge and self-efficacy) for recommended multimodal care. Clinical outcomes include pain intensity and neck pain-specific disability. Analyses from this study will focus on generating point estimates and corresponding 95

    Treatment results of neck dissection with the preservation of cervical nerves for hypopharyngeal cancer were analyzed retrospectively by comparing neck dissection with the preservation of cervical nerves and that with the resection of cervical nerves. Pharyngolaryngectomy or pharyngolaryngoesophagectomy with bilateral neck dissection was performed in 76 hypopharyngeal cancer cases between January 1992 and November 2001. Neck dissection with the resection of cervical nerves was performed on 42 sides of the neck in 21 cases (the cervical nerve-resected group). In 55 cases we attempted to employ neck dissection with the preservation of cervical nerves, but in 9 cases the cervical nerves were resected because of their nodal adhesion or involvement Neck dissection with the preservation of cervical nerves was performed on 92 sides of the neck in 46 cases (the cervical nerve-preserved group). There were significant differences between background factors of two groups about age, sex, induction chemotherapy, preservation of accessory nerve, and pN classification. The 5-year cumulative control rates of cervical lymph nodes were 81.3% for the cervical nerve-resected group and 79.7% for the cervical nerve-preserved group. There was no significant difference between the two groups. It was suggested that neck dissection with the preservation of cervical nerves for cases whose cervical nerves were able to be preserved from metastatic lymph nodes under induction chemotherapy and post-operative irradiation was as effective to control cervical lymph nodes as neck dissection with the resection of cervical nerves.

    After the age of 60 years, hip fracture risk strongly increases, but only a fifth of this increase is attributable to reduced bone mineral density (BMD, measured clinically). Changes in bone quality, specifically bone composition as measured by Fourier transform infrared spectroscopic imaging (FTIRI), also contribute to fracture risk. Here, FTIRI was applied to study the femoral neck and provide spatially derived information on its mineral and matrix properties in age-matched fractured and nonfractured bones. Whole femoral neck cross sections, divided into quadrants along the neck's axis, from 10 women with hip fracture and 10 cadaveric controls were studied using FTIRI and micro-computed tomography. Although 3-dimensional micro-CT bone mineral densities were similar, the mineral-to-matrix ratio was reduced in the cases of hip fracture, confirming previous reports. New findings were that the FTIRI microscopic variation (heterogeneity) of the mineral-to-matrix ratio was substantially reduced in the fracture group as was the heterogeneity of the carbonate-to-phosphate ratio. Conversely, the heterogeneity of crystallinity was increased. Increased variation of crystallinity was statistically associated with reduced variation of the carbonate-to-phosphate ratio. Anatomical variation in these properties between the different femoral neck quadrants was reduced in the fracture group compared with controls. Although our treatment-naive patients had reduced rather than increased bending resistance, these changes in heterogeneity associated with hip fracture are in another way comparable to the effects of experimental bisphosphonate therapy, which decreases heterogeneity and other indicators of bone's toughness as a material.

  13. Bilateral stress fracture of femoral neck in non-athlete - case report

    Directory of Open Access Journals (Sweden)

    Ubiratan Stefani de Oliveira

    Full Text Available ABSTRACT Bilateral stress fracture of femoral neck in healthy young patients is an extremely rare entity, whose diagnostic and treatment represent a major challenge. Patients with history of hip pain, even non-athletes or military recruits, should be analyzed to achieve an early diagnosis and prevent possible complications from the surgical treatment. This report describes a 43-year-old male patient, non-athlete, without previous diseases, who developed bilateral stress fracture of femoral neck without displacement. He had a late diagnosis; bilateral osteosynthesis was made using cannulated screws. Although the diagnosis was delayed in this case, the study highlights the importance of the diagnosis of stress fracture, regardless of the activity level of the patients, for the success of the treatment.

    A retrospective review of 396 patients with primary hyperparathyroidism (pHPT) treated surgically revealed a past history of neck external irradiation in 14 patients (35%). The mean interval between radiation exposure and the diagnosis of pHPT was 41 years (range, 31-49 years). All of the patients were women who had been exposed to radiation more than 31 years before. There was a significant difference in the male:female ratio of affected patients (p<0.001). The parathyroid histology was adenoma in 13 patients and carcinoma in one. In ten patients, normal parathyroid gland biopsies were undertaken. Among normal parathyroid glands from two patients, there were nodular lesions. Thirteen (93%) of the 14 patients who had undergone neck irradiation had thyroid nodular disease. In contrast, only 98 (26%) of the 382 patients who had not undergone neck external irradiation had thyroid nodular disease, and the difference between the two groups was significant (p<0.001). Neck irradiation has been shown to increase the risk of parathyroid and thyroid nodular diseases. If neck exploration is necessary in a patient who has received neck irradiation, both the thyroid and parathyroid glands should be carefully evaluated before and during surgery. (author)

    Full Text Available Lingual nerve injury or neuropraxia is a rare but potentially serious perioperative complication following airway instrumentation during general anesthesia. This study explored the the incidence and perioperative risk factors for lingual nerve injury in patients receiving laryngeal mask (LMA or endotracheal (ETGA general anesthesia in a single center experience.All surgical patients in our hospital who received LMA or ETGA from 2009 to 2013 were included, and potential perioperative risk factors were compared. Matched controls were randomly selected (in 1:5 ratio from the same database in non-case patients. A total of 36 patients in the records had reported experiencing tongue numbness after anesthesia in this study. Compared with the non-case surgical population (n = 54314, patients with tongue numbness were significantly younger (52.2±19.5 vs 42.0±14.5; P = 0.002 and reported lower ASA physical statuses (2.3±0.7 vs 1.6±0.6; P<0.001. Patient gender, anesthesia technique used, and airway device type (LMA or ETGA did not differ significantly across the two groups. A significantly higher proportion of patients underwent operations of the head-and-neck region (38.9 vs 15.6%; P = 0.002 developed tongue numbness after anesthesia. Multivariate logistic regression analysis indicated that head-and-neck operations remained the most significant independent risk factor for postoperative lingual nerve injury (AOR 7.63; 95% CI 2.03-28.70.The overall incidence rate of postoperative lingual neuropraxy was 0.066% in patients receiving general anesthesia with airway device in place. Young and generally healthy patients receiving head-and-neck operation are at higher risk in developing postoperative lingual neuropraxy. Attention should be particularly exercised to reduce the pressure of endotracheal tube or laryngeal mask on the tongue during head-and-neck operation to avert the occurrence of postoperative lingual neuropraxy.

    Lymphangiomas are uncommon benign congenital tumors. Most occur in the head and neck and most lesions present by the age of 2 years. We present our experience with four patients who have lymphangiomas of the head and neck with tongue involvement. First case is a 7-year-old male who has the cystic lymphangioma of left submandibular area. Second a 22-year-old female has a lesion involving the border of right tongue. Third case is the lymphangioma which occur in the right upper lip of a 6-year old male. The last patient is a 28-year old male who fell down and whose right face was swollen up. He had undergone an operation and treated with steroid before. The characteristic appearances of imaging methods were described and all lesions best depicted on T2-weighted images. Our experience indicates that MRI is useful in the diagnosis and treatment planning of lymphangioma.

    Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we summarize the recommendations of that group regarding best practices for planning, design and enrollment of cases and controls. Rigorous planning and preparation should focus on understanding the study context including healthcare-seeking and vaccination practices. Case-control vaccine effectiveness studies are best carried out soon after vaccine introduction because high coverage creates strong potential for confounding. Endpoints specific to the vaccine target are preferable to non-specific clinical syndromes since the proportion of non-specific outcomes preventable through vaccination may vary over time and place, leading to potentially confusing results. Controls should be representative of the source population from which cases arise, and are generally recruited from the community or health facilities where cases are enrolled. Matching of controls to cases for potential confounding factors is commonly used, although should be reserved for a limited number of key variables believed to be linked to both vaccination and disease. Case-control vaccine effectiveness studies can provide information useful to guide policy decisions and vaccine development, however rigorous preparation and design is essential.

    The cervical flexion relaxation ratio is lower in neck pain patients compared to healthy controls. Fatigue modulates the onset and offset angles of the silent period in both the lumbar and cervical spine in healthy individuals; however, this response has not been studied with neck pain patients. The purpose of this study was to determine if cervical extensor fatigue would alter the parameters of the cervical flexion relaxation more in a neck pain group than a healthy control group. Thirteen healthy and twelve neck pain patients participated. Cervical extensor activity was examined bilaterally and kinematics of the neck and head were collected. An isometric, repetitive neck extension task at 70% of maximum elicited fatigue. Participants performed 3 trials of maximal cervical flexion both pre and post fatigue. The healthy controls and neck pain groups fatigued after 56 (41) and 39 (31) repetitions, respectively. There was a significant interaction effect for the flexion relaxation ratio between the control and neck pain groups from pre to post fatigue trials (F1,96=22.67, P=0.0001), but not for onset and offset angles (F1, 96=0.017, P=0.897), although the onset and offset angles did decrease significantly for both groups following fatigue (F1,96=9.26, P=0.002). Individuals with mild to moderate neck pain have significant differences in their neuromuscular control relative to controls, experienced myoelectric fatigue with fewer repetitions in a shorter time, had a lower cervical flexion relaxation ratio at baseline and had an inability to decrease this ratio further in response to fatigue.

    To identify those risk factors that have the greatest impact on the incidence of head and neck injuries in international football. A case-control study of players sustaining head and neck injuries during 20 FIFA tournaments (men and women) from 1998 to 2004. Video recordings of incidents were used to identify a range of parameters associated with the incidents. Team physicians provided medical reports describing the nature of each injury. chi2 tests (pvideo sequences. The commonest injuries were contusions (53%), lacerations (20%), and concussions (11%). The incidence of all head and neck injuries was 12.5/1000 player hours (men 12.8, women 11.5) and 3.7 for lost-time injuries (men 3.5, women 4.1). The commonest causes of injury involved aerial challenges (55%) and the use of the upper extremity (33%) or head (30%). The unfair use of the upper extremity was significantly more likely to cause an injury than any other player action. Only one injury (a neck muscle strain) occurred as a result of heading the ball throughout the 20 tournaments equivalent to 0.05 injuries/1000 player hours. Players' actions most likely to cause a head or neck injury were the use of the upper extremity or the head but in the majority of cases these challenges were deemed to be fair and within the laws of the game.

    To evaluate the effect of training and pain education vs pain education alone, on neck pain, neck muscle activity and postural sway in patients with chronic neck pain. Twenty women with chronic neck pain were randomized to receive pain education and specific training (neck-shoulder exercises, balance and aerobic training) (INV), or pain education alone (CTRL). Effect on neck pain, function and Global Perceived Effect (GPE) were measured. Surface electromyography (EMG) was recorded from neck flexor and extensor muscles during performance of the Cranio-Cervical Flexion Test (CCFT) and three postural control tests (two-legged: eyes open and closed, one-legged: eyes open). Sway parameters were calculated. Fifteen participants (CTRL: eight; INV: seven) completed the study. Per protocol analyses showed a larger pain reduction (p = 0.002) for the INV group with tendencies for increased GPE (p = 0.06), reduced sternocleidomastoid activity during the CCFT (p = 0.09), reduced sway length (p = 0.09), and increased neck extensor activity (p = 0.02) during sway compared to the CTRL group. Pain education and specific training reduce neck pain more than pain education alone in patients with chronic neck pain. These results provide encouragement for a larger clinical trial to corroborate these observations. Copyright © 2015 Elsevier Ltd. All rights reserved.

    We treated 13 patients for femoral neck fracture. They consisted of 2 males and 11 females, and were classified according to Garden stage classification; Stage I, 3 cases; Stage II, 2 cases; Stage III, 2 cases; Stage IV, 4 cases. Two trochanteric fracture cases were used by control. We evaluated perfusion of the femoral head after femoral neck fracture using bone scintigraphy, which is considered useful for evaluation of perfusion of the femoral neck before operation. (author)

    Neck pain is associated with changes in neuromuscular control of cervical muscles. Violin and viola playing requires good function of the flexor muscles to stabilize the instrument. This study investigated the flexor muscle behaviour in violin/viola players with and without neck pain using the craniocervical flexion test (CCFT). In total, 12 violin/viola players with neck pain, 21 violin/viola players without neck pain in the preceding 12 weeks and 21 pain-free non-musicians were included. Activity of the sternocleidomastoid muscles (SCM) was measured with surface electromyography (EMG) during the CCFT. Violin/viola players with neck pain displayed greater normalised SCM EMG amplitudes during CCFT than the pain-free musicians and non-musicians (P neck pain in violinists/violists is associated with altered behaviour of the superficial neck flexor muscles consistent with neck pain, despite the specific use of the deep and superficial neck flexors during violin playing.

    Lipomas of the neck are uncommon lesions. Those situated in deep locations and diffuse lipomatosis of the neck can be clinically mis diagnosed. We reviewed the 20 lipomatous neck lesions treated in our hospital over a 15-year period (1985-1999). Computed tomography was diagnostic in nearly 100% of cases and, this, is the method of choice for the detection and characterization of lipomatous tumors. It also provides data that aid in planning the surgical approach and enables the follow-up of clinically stable lesions that do not require surgical treatment. (Author) 11 refs

    Full Text Available Introduction. Femoral neck fractures are very rare in young patients and are frequently complicated by femoral head osteonecrosis and femoral neck nonunion. Case Outline. A 19-year-old girl with hip dislocation following the treatment of the femoral neck fracture is presented. The femoral neck fracture was initially treated by open reduction and three-screw fixation. After detecting the nonunion of femoral neck, valgus osteotomy was done. Secondary, iatrogenic, hip dislocation appeared. The patient had pains, and in clinical findings a shorter leg and limited range of motion in the hip - altogether 40 degrees. She was then successfully treated by open reduction, together with Chiari pelvic osteotomy and joint transfixation. Transfixation pin was removed three weeks following the operation. After that, the patient was put into the abduction device and physical therapy was started. The mentioned regimen lasted four months after the surgery, then the abduction device was removed and walking started. Full weight bearing was allowed eight months after surgery. Conclusion. As we have not found the literature data concerning the above mentioned problem, we solved it in the way that we usually do for the treatment of developmental dislocation of the hip in adolescence.

    The ability of bone mineral density (BMD) to discriminate cervical and trochanteric hip fractures was studied. Since the majority of fractures occur among people who are not diagnosed as having osteoporosis, we also examined this population to elucidate whether geometrical risk factors can yield additional information on hip fracture risk beside BMD. The study showed that the T-score criterion was able to discriminate fracture patients from controls in the cases of trochanteric fractures, whereas geometrical measures may discriminate cervical fracture cases in patients with T-score >-2.5. Low bone mineral density (BMD) is a well-established risk factor for hip fracture. However, majority of fractures occur among people not diagnosed as having osteoporosis. We studied the ability of BMD to discriminate cervical and trochanteric hip fractures. Furthermore, we examined whether geometrical measures can yield additional information on the assessment of hip fracture risk in the fracture cases in subjects with T-score >-2.5. Study group consisted of postmenopausal females with non-pathologic cervical (n = 39) or trochanteric (n = 18) hip fracture (mean age 74.2 years) and 40 age-matched controls. BMD was measured at femoral neck, and femoral neck axis length, femoral neck and shaft cortex thicknesses (FNC and FSC), and femoral neck-shaft angle (NSA) were measured from radiographs. BMD T-score threshold of -2.5 was able to discriminate trochanteric fractures from controls (p trochanteric fractures occurred in individuals with T-score fractures. Twenty of these fractures (51.3%) occurred in individuals with BMD in osteoporotic range and 19 (48.7%) in individuals with T-score >-2.5. Within these non-osteoporotic cervical fracture patients (N = 19) and non-osteoporotic controls (N = 35), 83.3% were classified correctly based on a model including NSA and FNC (p trochanteric fractures could be discriminated based on a BMD T-score fracture cases would remain under-diagnosed if

    Full Text Available We developed a mental task with gaze direction recognition (GDR by which subjects observed neck rotation of another individual from behind and attempted to recognize the direction of gaze. A randomized controlled trial was performed in test (=9 and control (=8 groups of subjects with chronic neck pain undergoing physical therapy either with or without the GDR task carried out over 12 sessions during a three-week period. Primary outcome measures were defined as the active range of motion and pain on rotation of the neck. Secondary outcome measures were reaction time (RT and response accuracy in the GDR task group. ANOVA indicated a main effect for task session and group, and interaction of session. Post hoc testing showed that the GDR task group exhibited a significant simple main effect upon session, and significant sequential improvement of neck motion and relief of neck pain. Rapid effectiveness was significant in both groups. The GDR task group had a significant session-to-session reduction of RTs in correct responses. In conclusion, the GDR task we developed provides a promising rehabilitation measure for chronic neck pain.

    Case-Control study design is a type of observational study. In this design, participants are selected for the study based on their outcome status. Thus, some participants have the outcome of interest (referred to as cases), whereas others do not have the outcome of interest (referred to as controls). The investigator then assesses the exposure in both these groups. The investigator should define the cases as specifically as possible. Sometimes, definition of a disease may be based on multiple criteria; thus, all these points should be explicitly stated in case definition. An important aspect of selecting a control is that they should be from the same 'study base' as that of the cases. We can select controls from a variety of groups. Some of them are: General population; relatives or friends; and hospital patients. Matching is often used in case-control control studies to ensure that the cases and controls are similar in certain characteristics, and it is a useful technique to increase the efficiency of the study. Case-Control studies can usually be conducted relatively faster and are inexpensive - particularly when compared with cohort studies (prospective). It is useful to study rare outcomes and outcomes with long latent periods. This design is not very useful to study rare exposures. Furthermore, they may also be prone to certain biases - selection bias and recall bias.

    To assess the impact of modifications to radical neck dissection and radiotherapy on the postoperative quality of life, the study group 'Study on Standardization of Treatment for Lymph Node Metastasis of Head and Neck Cancer' performed a multicenter cross-sectional study using our self-administered neck dissection questionnaire and arm abduction test. While sparing levels IV and V improved most postoperative symptoms, such as stiffness and constriction of the neck were avoided as long as the sternocleidmastoid muscle (SCM) and the spinal accessory nerve were preserved. Resection of the SCM and spinal accessory nerve resulted in a drop shoulder and neck pain, respectively. Irradiation with a total dose of 50 Gy or more worsened stiffness of neck and shoulder.

    Full Text Available Superficial skin bleeding can usually be stopped by applying short-time compression, unless the patient suffers from coagulation disorders or uses anticoagulant. Because of the anticoagulant component of leech saliva, a leech bite may cause long-time bleeding, which cannot be stopped via compression.

    Neck pain is a common reason for seeking medical attention. It affects at least 15% of the labor force and up to 40% of individuals whose occupation is hazardous. On the other hand, primary bone lymphoma is a very rare disease (less than 1% of all malignant bone tumors), and the relationship between the 2 has rarely been mentioned. We report the case of a patient who had a 1-month history of neck pain. The main symptom was pain on palpation of C2-C6 cervical spinous processes and contracture of the trapezius muscle that did not cease with conventional treatment. Imaging studies indicated an abnormality. He underwent surgery and the results of vertebral biopsy were compatible with diffuse large B-cell lymphoma. He was treated with radiotherapy with a good outcome. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología. All rights reserved.

    Deep neck space abscesses (DNAs) are relatively common otolaryngology-head and neck surgery emergencies and can result in significant morbidity with potential mortality. Traditionally, surgical incision and drainage (I&D) with antibiotics has been the mainstay of treatment. Some reports have suggested that ultrasound-guided drainage (USD) is a less invasive and effective alternative in select cases. To compare I&D vs USD of well-defined DNAs, using a randomized controlled clinical trial design. The primary outcome measure was effectiveness (length of hospital stay (LOHS) and safety), and the secondary outcome measure was overall cost to the healthcare system. Patients presenting to the University of Alberta Emergency Department with a well-defined deep neck space abscess were recruited in the study. Patients were randomized to surgical or US-guided drainage, placed on intravenous antibiotics and admitted with airway precautions. Following drainage with either intervention, abscess collections were cultured and drains were left in place until discharge. Seventeen patients were recruited in the study. We found a significant difference in mean LOHS between patients who underwent USD (3.1 days) vs I&D (5.2 days). We identified significant cost savings associated with USD with a 41% cost reduction in comparison to I&D. USD drainage of deep neck space abscesses in a certain patient population is effective, safe, and results in a significant cost savings to the healthcare system.

    There is a high prevalence of neck pain in air force pilots; however, the causes are not clear and are considered work-related. Kyphotic changes in the cervical spine have been known to cause neck pain. In this study, we investigated the association between neck pain and cervical kyphosis in air force pilots. This is a cross-sectional study of 63 Republic of South Korea Air Force pilots. We examined the C2-7 absolute rotation angle (ARA) using the posterior tangent method and other radiologic parameters on whole spine lateral radiographs. We divided the participants into a neck pain group (N = 32) and no neck pain group (N = 31), and subsequently analyzed the difference in radiographic parameters and clinical data between the two groups. There were no significant differences found in age, body mass index, total flight time, or aerobic or anaerobic exercise between the neck pain and control groups. The fighter pilots had higher 1-yr prevalence of neck pain than nonfighter pilots (84.4% vs. 15.6%). The lower C2-7 ARA (OR = 0.91, 95% CI 0.846, 0.979) and fighter type aircrafts (OR = 3.93, 95% CI 1.104, 13.989) were associated with neck pain. Fighter pilots experienced neck pain more frequently than the nonfighter pilots. Those fighter pilots suffering from neck pain were shown to have more kyphotic changes in the cervical spine than control pilots through evaluation of whole spine lateral radiographs using the posterior tangent method. These key findings suggest that the forces involved in flying a fighter type aircraft may affect cervical alignment and neck pain.

    Although neck pain is a common musculoskeletal disorder, there is no consensus on suitable exercise methods for middle-aged and senior patients with chronic neck pain. Therefore, this study investigated the effectiveness of a 6-week shoulder-neck exercise intervention program on cervical muscle function improvement in patients aged 45 years or older with chronic neck pain. The aim of the present study was to evaluate the effects of progressive shoulder-neck exercise on cervical muscle functions of middle-aged and senior patients with chronic neck pain. A randomized controlled single-blind trial. Rehabilitation department of a hospital. A total of 72 subjects aged ≥45 years with chronic neck pain were randomly allocated to either an experimental group (N.=36; age 57.3±8.74 years) or a control group (N.=36; age 58.15±8.17 years). The control group received only traditional physiotherapy, whereas the experimental group participated in a 6-week shoulder-neck exercise program consisting of cranio-cervical flexion and progressive resistance exercises in addition to receiving traditional physiotherapy. The muscle functions of subjects in both groups were tested before the experiment and also after the intervention program. The pretest and posttest measured the cranio-cervical flexion test (CCFT) and the superficial cervical muscle strength. After the intervention, the experimental group had a 56.48 point improvement in the performance index of the CCFT (Pcervical muscle functions. This study confirmed that the 6-week progressive shoulder-neck exercise program can effectively improve cervical muscle function in middle-aged and senior patients with chronic neck pain. Progressive shoulder-neck exercise might provide positive effect on deep and superficial neck muscle strength in patients with chronic neck pain. Therefore, this study may serve as a reference for the clinical rehabilitation of patients with chronic neck pain.

    Is the use of harmonic scalpel for neck dissection useful? Literature search did not show a single, prospective, randomised control trial. We intended to study the role of harmonic scalpel in neck dissection and compare it with conventional electrocautery technique for oral cavity carcinoma. 40 patients undergoing selective neck dissection for primary oral cavity malignancy were enrolled in this study. The harmonic scalpel (HS) group consisted of 20 patients, and the electrocautery technique (ET) group comprised of 20 patients. The following variables were examined: intraoperative blood loss, operative time, number of ligatures used, postoperative drain, and postoperative hospital stay. Intraoperative blood loss was found to be significantly reduced in harmonic scalpel group as compared to electrocautery group. However, we found no difference in other parameters like operative time, postop drain, postoperative hospital stay and number of ligatures used between both groups. Harmonic scalpel for neck dissection is associated with significantly lesser intraoperative blood loss as compared to electrocautery. There is no effect on operative time and postoperative hospital stay in both groups. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    A meta-analysis. The aim of this study was to perform a comprehensive search of current literature and conduct a meta-analysis of randomized controlled trials (RCTs) to assess the neck pain relieving effect of intermittent cervical traction (ICT). Neck pain is a common and disabling problem with a high prevalence in general population. It causes a considerable burden on the health care system with a substantial expenditure. ICT is a common component of physical therapy for neck pain in the outpatient clinic. However, the evidence regarding the effectiveness of ICT for neck pain is insufficient. Data were obtained from the PubMed, Cochrane Library, Embase, and Scopus databases from the database inception date to July 02, 2016. RCTs reporting the effects of ICT on neck pain, including those comparing the effects of ICT with those of a placebo treatment, were included. Two reviewers independently reviewed the studies, conducted a risk of bias assessment, and extracted data. The data were pooled in a meta-analysis by using a random-effects model. The meta-analysis included seven RCTs. The results indicated that patients who received ICT for neck pain had significantly lower pain scores than those receiving placebos did immediately after treatment (standardized mean difference = -0.26, 95% confidence interval = -0.46 to -0.07). The pain scores during the follow-up period and the neck disability index scores immediately after treatment and during the follow-up period did not differ significantly. ICT may have a short-term neck pain-relieving effect. Some risks of bias were noted in the included studies, reducing the evidence level of this meta-analysis. Additional high-quality RCTs are required to clarify the long-term effects of ICT on neck pain. 1.

    Studies defined as case-control do not always use this design. We aimed to estimate the frequency of mislabelled case-control studies in published articles in the area of diabetes and to identify the predictors of incorrect labelling. We searched Medline and Web of Science for articles with "diabetes" and "case control" in title and filtered for language (English/Romance) and period (January 2010-December 2014). Inclusion criteria were: (1) statement to use a case-control design in title, (2) to be a final full-length publication and (3) to have original data in the area of diabetes. Three independent reviewers went through titles, looked for full texts and reviewed them. Discrepancies were settled with a fourth reviewer. Expert epidemiologist advice was requested in case of doubt. case-control mislabelling; addressed predictors: publication year, journal impact factor and journal subject. proportion of mislabelled CC articles and assessment of predictors by multivariate logistic regression analysis. We retrieved 362 articles, 251 of them fulfilling inclusion criteria. The proportion of mislabelled CC studies was 43.8% (confidence interval 95% 37.7-50.0%). Most mislabelled studies had a cross-sectional design (82.7%). Predictors of mislabelling were publication year, journal impact factor and journal area. A relevant subset of studies defined as case-control in the area of diabetes correspond to mislabelled cross-sectional studies. Incorrect labelling misleads readers regarding the interpretation of results and the cause-effect hypothesis. Researchers, reviewers and editors should be aware of and commit to settle this issue.

    Although the relationship between allergy and cancer has been investigated extensively, the role of allergy in head and neck cancer (HNC) appears less consistent. It is not clear whether allergies can independently influence the risk of HNC in the presence of known strong environmental risk factors, including consumption of alcohol, betel quid, and cigarette. THE CURRENT PAPER REPORTS RESULTS FROM: 1) an original hospital-based case-control study, which included 252 incident cases of HNC and 236 controls frequency-matched to cases on sex and age; and 2) a meta-analysis combining the results of the current case-control study and 13 previously published studies (9 cohort studies with 727,569 subjects and 550 HNC outcomes and 5 case-control studies with 4,017 HNC cases and 10,928 controls). In the original case-control study, we observed a strong inverse association between allergies and HNC [odds ratio = 0.41, 95% confidence interval (CI): 0.27-0.62]. The meta-analysis also indicated a statistically significant inverse association between HNC and allergies [meta-relative risk (RR) = 0.76, 95% CI: 0.63-0.91], particularly strong for allergic rhinitis (meta-RR = 0.55, 95% CI: 0.40-0.76). In addition, the inverse association between allergies and HNC was observed only among men (meta-RR = 0.67, 95% CI: 0.54-0.84) but not among women (meta-RR = 0.98, 95% CI: 0.81-1.18). These findings suggest that immunity plays an influential role in the risk of HNC. Future studies investigating immune biomarkers, including cytokine profiles and genetic polymorphisms, are warranted to further delineate the relationship between allergies and HNC. Understanding the relationship between allergies and HNC may help devise effective strategies to reduce and treat HNC.

    Full Text Available Chondrosarcoma originates in the bones of the head and neck. It is an unusual neoplasm that is slow-growing and represents only 1–3% of all cases of chondrosarcoma. Here, we report a case of a 45-year-old male Caucasian patient treated at Hospital Amaral Carvalho with a history of swelling of the face and a tumoral mass in the right maxilla with infiltration into the skin, which had been present for 4 months. A computerized tomography (CT of the face and sinuses demonstrated a lesion in the right maxilla. A maxilectomia without orbital exenteration was performed. It was diagnosed as a grade III chondrosarcoma, with infiltration into the subjacent bone, anterior wall of the maxillary sinus and floor of the orbit. The patient presented with recurrence of the tumor after adjuvant therapies. A molecular study on the present case showed an unusually large number of abnormalities. This finding demonstrated extreme chromosomal instability, which was likely due to the undifferentiation of the tumor. Although there are no cases in the literature with which to compare, these findings may elucidate potential therapeutic targets for advanced tumors without other therapeutic options.

    We examined the association of ABO blood groups with the different types of head and neck cancers. 195 diagnosed cases and 801 controls were selected from a Greek tertiary cancer center. Information regarding type of head and neck cancer and ABO blood group was collected and registered. The O blood group was found to be most prevalent followed by A, B and AB among the controls, whereas blood group A followed by O, B and AB was most prevalent among cancer patients. The difference among the distribution between the cases and controls was statistically significant in blood group A (pblood group A had 1.52-fold higher risk of developing head and neck cancer compared to people of other blood groups. Blood group A was found to be a potential risk factor for the development of head and neck cancers.

    Purpose: To investigate the feasibility of ultrasound Nakagami imaging to quantitatively assess radiation-induced neck fibrosis, a common sequela of radiation therapy (RT) to the head and neck. Methods and Materials: In a pilot study, 40 study participants were enrolled and classified into 3 subgroups: (1) a control group of 12 healthy volunteers; (2) an asymptomatic group of 11 patients who had received intensity modulated RT for head and neck cancer and had experienced no neck fibrosis; and (3) a symptomatic group of 17 post-RT patients with neck fibrosis. Each study participant underwent 1 ultrasound study in which scans were performed in the longitudinal orientation of the bilateral neck. Three Nakagami parameters were calculated to quantify radiation-induced tissue injury: Nakagami probability distribution function, shape, and scaling parameters. Physician-based assessments of the neck fibrosis were performed according to the Radiation Therapy Oncology Group late morbidity scoring scheme, and patient-based fibrosis assessments were rated based on symptoms such as pain and stiffness. Results: Major discrepancies existed between physician-based and patient-based assessments of radiation-induced fibrosis. Significant differences in all Nakagami parameters were observed between the control group and 2 post-RT groups. Moreover, significant differences in Nakagami shape and scaling parameters were observed among asymptomatic and symptomatic groups. Compared with the control group, the average Nakagami shape parameter value increased by 32.1% (P<.001), and the average Nakagami scaling parameter increased by 55.7% (P<.001) for the asymptomatic group, whereas the Nakagami shape parameter increased by 74.1% (P<.001) and the Nakagami scaling parameter increased by 83.5% (P<.001) for the symptomatic group. Conclusions: Ultrasonic Nakagami imaging is a potential quantitative tool to characterize radiation-induced asymptomatic and symptomatic neck fibrosis.

    Full Text Available Abstract Background Many patients suffer from chronic neck pain following a whiplash injury. A combination of cognitive, behavioural therapy with physiotherapy interventions has been indicated to be effective in the management of patients with chronic whiplash-associated disorders. The objective is to present the design of a randomised controlled trial (RCT aimed at evaluating the effectiveness of a combined individual physical and cognitive behavioural-graded activity program on self-reported general physical function, in addition to neck function, pain, disability and quality of life in patients with chronic neck pain following whiplash injury compared with a matched control group measured at baseline and 4 and 12 months after baseline. Methods/Design The design is a two-centre, RCT-study with a parallel group design. Included are whiplash patients with chronic neck pain for more than 6 months, recruited from physiotherapy clinics and an out-patient hospital department in Denmark. Patients will be randomised to either a pain management (control group or a combined pain management and training (interventiongroup. The control group will receive four educational sessions on pain management, whereas the intervention group will receive the same educational sessions on pain management plus 8 individual training sessions for 4 months, including guidance in specific neck exercises and an aerobic training programme. Patients and physiotherapists are aware of the allocation and the treatment, while outcome assessors and data analysts are blinded. The primary outcome measures will be Medical Outcomes Study Short Form 36 (SF36, Physical Component Summary (PCS. Secondary outcomes will be Global Perceived Effect (-5 to +5, Neck Disability Index (0-50, Patient Specific Functioning Scale (0-10, numeric rating scale for pain bothersomeness (0-10, SF-36 Mental Component Summary (MCS, TAMPA scale of Kinesiophobia (17-68, Impact of Event Scale (0-45, EuroQol (0

    Deep-neck infection (DNI) remains potentially fatal. We retrospectively analyzed 299 surgically treated DNI cases between January 1997 and October 2007 by reviewing computed tomography (CT) results and discuss treatment and risk factors. Subjects were divided into two groups by abscess-site; peritonsillar abscess (PTA) (n=251) and deep-neck abscess (DNA) (n=48). Age, smoking habits, body mass index (BMI) and bacteriological histories were collected from clinical records and compared by group. DNI and PTA severity parameters were C-reactive protein (CRP) titer and hospitalization length. Median subject age in DNI was 51.0 years and peak incidence in the 50 s. Median subject age in PTA was 31.0 years and the peak incidence in the 20 s. Smoker prevalence was higher in both groups than in normal healthy subjects. The DNI group had higher BMI and diabetes mellitus. Factors potentially most affecting illness were complications such as obesity and diabetes mellitus in DNI and age in PTA. (author)

    Radiotherapy is associated with a risk of subsequent neoplasms (SN) in childhood cancer survivors. It has been shown that children’s thyroid glands are especially susceptible. The aim is to quantify the risk of a second neck neoplasm after primary cancer radiotherapy with emphasis on thyroid cancer. We performed a nested case–control study: 29 individuals, diagnosed with a solid SN in the neck region, including 17 with thyroid cancer, in 1980–2002 and 57 matched controls with single neoplasms were selected from the database of the German Childhood Cancer Registry. We investigated the risk associated with radiotherapy exposure given per body region, adjusted for chemotherapy. 16/17 (94.1 %) thyroid SN cases, 9/12 (75 %) other neck SN cases and 34/57 (59.6 %) controls received radiotherapy, with median doses of 27.8, 25 and 24 Gy, respectively. Radiotherapy exposure to the neck region increased the risk of the other neck SNs by 4.2 % (OR = 1.042/Gy (95 %-CI 0.980-1.109)) and of thyroid SN by 5.1 % (OR = 1.051/Gy (95 %-CI 0.984-1.123)), and radiotherapy to the neck or spine region increased the thyroid risk by 6.6 % (OR = 1.066/Gy (95 %-CI 1.010-1.125)). Chemotherapy was not a confounder. Exposure to other body regions was not associated with increased risk. Radiotherapy in the neck or spine region increases the risk of thyroid cancer, while neck exposure increases the risk of any other solid SN to a similar extent. Other studies showed a decreasing risk of subsequent thyroid cancer for very high doses; we cannot confirm this

    [Purpose] This study examined the effects of deep flexor muscle-strengthening exercise on the neck-shoulder posture, and the strength and endurance of the deep flexor muscles of high-school students. [Subjects] The subjects were 30 seventeen-year-old female high-school students who complained about bad posture and chronic neck-shoulder pain. They were randomly divided into an experimental group of 15 subjects, who performed a deep flexor muscle-strengthening exercise and a control group of 15 subjects, who performed a basic stretching exercise. [Methods] The experimental group of 15 subjects performed a deep flexor muscle-strengthening exercise consisting of low-load training of the cranio-cervical flexor muscle, and the control group of 15 subjects performed a basic stretching exercise consisting of seven motions. [Results] The experimental group showed statistically significant changes in head tilt angle, neck flexion angle, forward shoulder angle, and the result of the cranio-cervical flexion test after the training. In contrast, the control group showed no statistically significant changes in these measures following the training. When the results of the groups were compared, statistically significant differences were found for all items between the experimental group and the control group. [Conclusion] Strengthening cranio-cervical flexor muscles is important for the adjustment of neck posture, and maintaining their stability is required to improve neck-shoulder posture.

  12. Accounting for control mislabeling in case-control biomarker studies.

    2011-12-02

    In biomarker discovery studies, uncertainty associated with case and control labels is often overlooked. By omitting to take into account label uncertainty, model parameters and the predictive risk can become biased, sometimes severely. The most common situation is when the control set contains an unknown number of undiagnosed, or future, cases. This has a marked impact in situations where the model needs to be well-calibrated, e.g., when the prediction performance of a biomarker panel is evaluated. Failing to account for class label uncertainty may lead to underestimation of classification performance and bias in parameter estimates. This can further impact on meta-analysis for combining evidence from multiple studies. Using a simulation study, we outline how conventional statistical models can be modified to address class label uncertainty leading to well-calibrated prediction performance estimates and reduced bias in meta-analysis. We focus on the problem of mislabeled control subjects in case-control studies, i.e., when some of the control subjects are undiagnosed cases, although the procedures we report are generic. The uncertainty in control status is a particular situation common in biomarker discovery studies in the context of genomic and molecular epidemiology, where control subjects are commonly sampled from the general population with an established expected disease incidence rate.

    To determine whether simultaneous (ablation and reconstruction overlaps by two teams) head and neck reconstruction is cost effective compared to sequentially (ablation followed by reconstruction) performed surgery. Case-controlled study. Tertiary care hospital. Oncology patients undergoing free flap reconstruction of the head and neck. A match paired comparison study was performed with a retrospective chart review examining the total time of surgery for sequential and simultaneous surgery. Nine patients were selected for both the sequential and simultaneous groups. Sequential head and neck reconstruction patients were pair matched with patients who had undergone similar oncologic ablative or reconstructive procedures performed in a simultaneous fashion. A detailed cost analysis using the microcosting method was then undertaken looking at the direct costs of the surgeons, anesthesiologist, operating room, and nursing. On average, simultaneous surgery required 3 hours 15 minutes less operating time, leading to a cost savings of approximately $1200/case when compared to sequential surgery. This represents approximately a 15% reduction in the cost of the entire operation. Simultaneous head and neck reconstruction is more cost effective when compared to sequential surgery.

    The clinical diagnosis of a mass in the neck region encompasses a wide spectrum of differential diagnosis. Fine-needle aspiration is a quick and safe technique, which can provide useful information for initial assessment and further therapeutic measures. The aim of this retrospective study was to evaluate the performance characteristics of the fine-needle aspiration (FNA) in cystic neck lesions. Of 142 patients with FNA for cystic neck masses during 2002-2007, 92 cases were selected with a follow-up histologic diagnosis, excluding the cystic colloid nodule of the thyroid. The cases were divided into salivary gland cystic neck (37 patients) and non-salivary cystic neck (55 patients) mass groups. False-positive and false-negative diagnoses were applied only to the malignant lesions after confirmation by histopathology. In the first group, nine malignant and 28 benign diagnoses were made by FNA; of which three were false-negative. In the second group, there were nine malignant and 46 benign diagnoses with three false negatives. The overall performance of the FNA showed 76% sensitivity and 100% specificity. In conclusion, FNA of the cystic neck lesions offers an invaluable and highly specific initial diagnostic approach for the management of the patients. (c) 2009 Wiley-Liss, Inc.

    Marijuana is the most commonly used illegal drug in the United States. In some subcultures, it is widely perceived to be harmless. Although the carcinogenic properties of marijuana smoke are similar to those of tobacco, no epidemiological studies of the relationship between marijuana use and head and neck cancer have been published. The relationship between marijuana use and head and neck cancer was investigated by a case-control study of 173 previously untreated cases with pathologically confirmed diagnoses of squamous cell carcinoma of the head and neck and 176 cancer-free controls at Memorial Sloan-Kettering Cancer Center between 1992 and 1994. Epidemiological data were collected by using a structured questionnaire, which included history of tobacco smoking, alcohol use, and marijuana use. The associations between marijuana use and head and neck cancer were analyzed by Mantel-Haenszel methods and logistic regression models. Controlling for age, sex, race, education, alcohol consumption, pack-years of cigarette smoking, and passive smoking, the risk of squamous cell carcinoma of the head and neck was increased with marijuana use [odds ratio (OR) comparing ever with never users, 2.6; 95% confidence interval (CI), 1.1-6.6]. Dose-response relationships were observed for frequency of marijuana use/day (P for trend marijuana use (P for trend marijuana use were observed with cigarette smoking, mutagen sensitivity, and to a lesser extent, alcohol use. Our results suggest that marijuana use may increase the risk of head and neck cancer with a strong dose-response pattern. Our analysis indicated that marijuana use may interact with mutagen sensitivity and other risk factors to increase the risk of head and neck cancer. The results need to be interpreted with some caution in drawing causal inferences because of certain methodological limitations, especially with regard to interactions.

    Elective treatment of lymph nodes in oropharyngeal cancer (OPC) has impact on both regional recurrences (RR) and risk of late side effects. This study was performed to quantify the dose-dependent impact on RR and overall survival (OS) in a prospectively collected cohort of OPC from the ARTSCAN study with emphasis on elective treatment. ARTSCAN is a previously published prospective, randomized, multicentre study of altered radiotherapy (RT) fractionation in head and neck cancer. In ARTSCAN the elective treatment volume for node positive OPC varied significantly between centres due to local treatment principles. All patients with OPC in complete response after primary treatment were eligible for the present case–control study. Cases were patients with RR during five years follow-up. Patients with no recurrence were eligible as controls. Four controls per case were matched according to T- and N-stage. Mean (D mean ) and median (D 50% ) dose for the lymph node level (LNL) of RR in the cases and the corresponding LNL in the controls were analysed with conditional logistic regression. OS was estimated with the Kaplan-Meier method and evaluated by multivariate Cox regression analysis. There was a dose-dependent risk reduction for D 50% in the interval that represented elective treatment (40–50 Gy) (OR = 0.18, p < 0.05) and a trend in the same dose interval for D mean (OR = 0.19, p = 0.07). OS rates at five years were 0.39 (0.24-0.65) for cases and 0.70 (0.62–0.81) for controls (p < 0.001). The Kaplan-Meier and the Cox regression analysis for cases categorised by delivered dose showed an inverse relationship between dose and survival. The cases with RR in a LNL outside planning target volume (PTV) (D mean < 40 Gy) had an OS rate comparable to that of all patients, and those with RR in a LNL in PTV elective (D mean 40–60 Gy) or PTV tumour (D mean >60 Gy) did significantly worse (p < 0.05). The same inverse relationship was also shown for a small subset of patient

  17. Atypical femoral neck stress fracture in a marathon runner: a case report and literature review.

    LENUS (Irish Health Repository)

    2012-02-01

    BACKGROUND: Femoral neck stress fractures are relatively rare and may present as sports-related injuries. The presentation is variable, and prompt diagnosis facilitates the earliest return to pre-morbid functional activity levels. Delayed detection may precipitate femoral non-union or avascular necrosis, resulting in long-term functional deficit. AIMS: We present the case of a basicervical femoral neck stress fracture occurring in a 23-year-old marathon runner. The pathophysiology and practical management issues related to this unusual injury pattern are discussed. CONCLUSION: The growing interest in amateur athletic activities should raise the index of suspicion for stress fractures of the femoral neck in healthy adults with atypical hip pain. Increased levels of patient education and physician awareness can reduce the incidence of long-term morbidity in cases of this unusual sports-related injury.

    Deep neck space infections, which affect soft tissues and fascial compartments of the head and neck, can lead to lethal complications unless treated carefully and quickly, even with the advanced antibiotics available. We reviewed our seventeen patients with deep neck abscesses, analyzed their location by reviewing CT images, and discussed the treatment. Deep neck space infections were classified according to the degree of diffusion of infection diagnosed by CT images. Neck space infection in two cases was localized to the upper neck space above the hyoid bone (Stage I). Neck space infection in 12 cases extended to the lower neck space (Stage II), and further extended to the mediastinum in one case (Stage III). The two cases of Stage I and the four cases of Stage II were managed with incision and drainage through a submental approach. The seven cases of Stage II were managed with incision and drainage parallel to the anterior border of the sternocleidomastoid muscle, the ''Dean'' approach. The one case of Stage III received treatment through transcervicotomy and anterior mediastinal drainage through a subxiphodal incision. The parapharyngeal space played an important role in that the inflammatory change can spread to the neck space inferiorly. The anterior cervical space in the infrahyoid neck was important for mediastinal extension of parapharyngeal abscesses. It is important to diagnose deep neck space infections promptly and treat them adequately, and contrast-enhanced CT is useful and indispensable for diagnosis. The point is which kind of drainage has to be performed. If the surgical method of drainage is chosen according to the level of involvement in the neck space and mediastinum, excellent results may be obtained in terms of survival and morbidity. (author)

    Head and neck squamous cell carcinoma is the most commonly diagnosed cancer worldwide. The lifestyle, food habits, and customary practices manifest the Northeast Indian population toward higher susceptibility to develop head and neck squamous cell carcinoma. Here, we have investigated the association of smoke and smokeless tobacco, and alcohol with copy number variation of cell-free mitochondrial DNA and cell-free nuclear DNA in cases and controls. Cell-free DNA from plasma was isolated from 50 head and neck squamous cell carcinoma cases and 50 controls with informed written consent using QIAamp Circulating Nucleic Acid Kit. Real-time polymerase chain reaction was done for copy number variation in cell-free mitochondrial DNA and cell-free nuclear DNA. Receiver operating characteristic curve analysis was performed to evaluate the diagnostic application between the two study groups using clinicopathological parameters. The levels of cell-free nuclear DNA and cell-free mitochondrial DNA of cases in association with smoke and smokeless tobacco, alcohol with smoking (p squamous cell carcinoma cases and controls, we distinguished cell-free mitochondrial DNA (cutoff: 19.84 raw Ct; sensitivity: 84%; specificity: 100%; p < 0.001) and cell-free nuclear DNA (cutoff: 463,282 genomic equivalent/mL; sensitivity: 53%; specificity: 87%; p < 0.001). The copy number variation in cases (cell-free nuclear DNA: 5451.66 genomic equivalent/mL and cell-free mitochondrial DNA: 29,103,476.15 genomic equivalent/mL) and controls (cell-free nuclear DNA: 1650.9 genomic equivalent/mL and cell-free mitochondrial DNA: 9,189,312.54 genomic equivalent/mL), respectively. Our result indicates that the cell-free mitochondrial DNA content is highly associated with smoke and smokeless tobacco, betel quid chewing, and alcohol which shows greater promises, holding the key characteristics of diagnostic biomarkers, that is, minimal invasiveness, high specificity, and sensitivity.

    The purpose of this study was to evaluate the efficacy of CyberKnife for recurrent previously irradiated head and neck cancer. Thirty-one patients with recurrent previously irradiated head and neck cancer were treated with a CyberKnife from July 1999 to March 2002 at Okayama Kyokuto Hospital were retrospectively studied. The accumulated dose was 28-80 Gy (median 60 Gy). The interval between CyberKnife treatment and previous radiotherapy was 0.4-429.5 months (median 16.3 months). Primary lesions were nasopharynx: 7, maxillary sinus: 6, tongue: 5, ethmoid sinus: 3, and others: 1. The pathology was squamous cell carcinoma: 25, adenoid cystic carcinoma: 4, and others: 2. Symptoms were pain: 8, and nasal bleeding: 2. The prescribed dose was 15.0-40.3 Gy (median 32.3 Gy) as for the marginal dose. The response rate (complete response (CR)+partial response (PR)) and local control rate (CR+PR+no change (NC)) was 74% and 94% respectively. Pain disappeared for 4 cases, relief was obtained for 4 cases and no change for 2 cases and nasal bleeding disappeared for 2 cases for an improvement of symptoms. An adverse effects were observed as mucositis in 5 cases and neck swelling in one case. Prognosis of recurrent previously irradiated head and neck cancer was estimated as poor. Our early experience shows that CyberKnife is expected to be feasible treatment for recurrent previously irradiated head and neck cancer, and for the reduction adverse effects and maintenance of useful quality of life (QOL) for patients.

    Manipulation and mobilisation are commonly used to treat neck pain. This is an update of a Cochrane review first published in 2003, and previously updated in 2010. To assess the effects of manipulation or mobilisation alone compared wiith those of an inactive control or another active treatment on pain, function, disability, patient satisfaction, quality of life and global perceived effect in adults experiencing neck pain with or without radicular symptoms and cervicogenic headache (CGH) at immediate- to long-term follow-up. When appropriate, to assess the influence of treatment characteristics (i.e. technique, dosage), methodological quality, symptom duration and subtypes of neck disorder on treatment outcomes. Review authors searched the following computerised databases to November 2014 to identify additional studies: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We also searched ClinicalTrials.gov, checked references, searched citations and contacted study authors to find relevant studies. We updated this search in June 2015, but these results have not yet been incorporated. Randomised controlled trials (RCTs) undertaken to assess whether manipulation or mobilisation improves clinical outcomes for adults with acute/subacute/chronic neck pain. Two review authors independently selected studies, abstracted data, assessed risk of bias and applied Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methods (very low, low, moderate, high quality). We calculated pooled risk ratios (RRs) and standardised mean differences (SMDs). We included 51 trials (2920 participants, 18 trials of manipulation/mobilisation versus control; 34 trials of manipulation/mobilisation versus another treatment, 1 trial had two comparisons).

    Cross-sectional study. To explore aspects of cervical musculoskeletal function in female office workers with neck pain. Evidence of physical characteristics that differentiate computer workers with and without neck pain is sparse. Patients with chronic neck pain demonstrate reduced motion and altered patterns of muscle control in the cervical flexor and upper trapezius (UT) muscles during specific tasks. Understanding cervical musculoskeletal function in office workers will better direct intervention and prevention strategies. Measures included neck range of motion; superficial neck flexor muscle activity during a clinical test, the craniocervical flexion test; and a motor task, a unilateral muscle coordination task, to assess the activity of both the anterior and posterior neck muscles. Office workers with and without neck pain were formed into 3 groups based on their scores on the Neck Disability Index. Nonworking women without neck pain formed the control group. Surface electromyographic activity was recorded bilaterally from the sternocleidomastoid, anterior scalene (AS), cervical extensor (CE) and UT muscles. Workers with neck pain had reduced rotation range and increased activity of the superficial cervical flexors during the craniocervical flexion test. During the coordination task, workers with pain demonstrated greater activity in the CE muscles bilaterally. On completion of the task, the UT and dominant CE and AS muscles demonstrated an inability to relax in workers with pain. In general, there was a linear relationship between the workers' self-reported levels of pain and disability and the movement and muscle changes. These results are consistent with those found in other cervical musculoskeletal disorders and may represent an altered muscle recruitment strategy to stabilize the head and neck. An exercise program including motor reeducation may assist in the management of neck pain in office workers.

    Purpose: To evaluate MR imaging of the hip in patients with a clinically suspected impacted fracture of the femoral neck in cases where conventional plain films show negative or equivocal findings. Material and Methods: Twenty-seven such patients were prospectively examined by MR imaging with a 1.0 T unit, within 24 hours of admittance to hospital. A coronal T1-weighted turbo spin-echo sequence (n=27), and a coronal STIR sequence (n=25) or a coronal T2-weighted turbo spin-echo fast saturation sequence (n=2) were used. The evaluations were made by 2 radiologists with experience in musculoskeletal radiology. Results: There were 6 patients with a petrochanteric fracture, 2 without and 4 with slight displacement. Five patients had an impacted fracture of the femoral neck, and 3 had a fracture of the superior pubic bone. Of 2 patients with advanced arthrosis, i had an impacted femoral neck fracture and the other a nondisplaced intertrochanteric fracture. There was 1 patient who had sustained a nondisplaced acetabular fracture with increased joint fluid and muscle contusions. Three patients had muscle contusions only. Two patients had bone marrow contusions only, while 2 others with advanced coxarthrosis had increased joint fluid only. Three patients showed normal findings. Our findings led to emergency surgery in 13 cases, and conservative measures directed to the specific MR findings in 14 patients. Conclusion: MR imaging should be the first modality of choice in examining patients with a clinically suspected impacted fracture of the femoral neck where conventional films show negative or equivocal findings.

    Full Text Available Introduction: Desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   Case Report: The patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. His CT-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. Biopsy was compatible with desmoid fibromatosis.  He was given neoadjovant treatment with vinblastin and methotrexate. The patient underwent a tracheostomy. Then a complete hemimandibulectomy and submandibular gland excision was performed.  Finally reconstruction with latisimus dorsi free flap was performed.   Conclusion: Despite rarity desmoid tumors should be kept in mind of an otorhinolaryngologist as a differential diagnosis in children with head and neck mass.

    Full Text Available AIMS AND OBJECTIVES To find out the role of multidetector computed tomography in the evaluation of neck lesions with respect to evaluation of the size, location and extent of tumour. Extension of tumour infiltrating into surrounding vascular and visceral structures. To correlate the findings of MD-CT with final diagnosis by biopsy. MATERIAL AND METHODS Data for the study was collected from patients with suspected neck lesions attending Department of Radio-diagnosis, J.L.N. Medical College and Associated Group of Hospitals, Ajmer, Rajasthan. A prospective study was conducted over a period (From 1st March 2014 to 31 Aug. 2015 on patients with clinically suspected neck lesions or patients who were diagnosed to have neck lesion on ultrasound and were referred to CT for further characterisation. The patients presented with symptoms of palpable neck mass and neck pain. Patients were evaluated using multidetector CT. A provisional diagnosis was made after CT scan and these findings were correlated with histopathology/surgical findings as applicable. RESULT In the present study, 97 out of 100 cases were correctly characterised by computed tomography giving an accuracy of 97%. One case of buccal carcinoma was wrongly diagnosed as benign lesion and another case of malignant lymph node was inaccurately diagnosed as benign lymph node, also another case of benign lymph node was inaccurately diagnosed as malignant lymph node. CONCLUSION Multidetector Computed Tomography of the neck has improved the localisation and characterisation of neck lesions. Accurate delineation of disease by CT scan provides a reliable preoperative diagnosis, plan for radiotherapy ports and posttreatment followup. However, histopathology still remains the gold standard as CT is not 100% accurate.

  14. Review of patients with dysphasia after a neck dissection

    The most useful modality for treating neck metastasis is a neck dissection. A neck dissection was previously performed as a radical neck dissection. However, disabilities in shoulder movement and swallowing function often occur after this procedure. Recently, a functional neck dissection has therefore been performed in order to avoid such postoperative complications. The current study for dysphasia after a neck dissection investigates patients with primary unknown neck metastasis and neck recurrence after chemoradiation. Eleven cases of dysphasia occurred after a neck dissection between 2003 and 2006. These cases resected the lower cranial nerves (IX, X, XII), or paralysis of these nerves occurred despite their preservation after surgery. Patients with dysphasia underwent rehabilitation to regain their swallowing function. However, rehabilitation was unsuccessful and the patients were thus required to undergo further surgery. A neck dissection with resection of the lower cranial nerves (IX, X, XII) may sometimes result in dysphasia. Consequently, surgery to prevent dysphasia should be performed simultaneously so that timely postoperative therapy can be carried out. (author)

    Background: The aim of this multi-center phase II study was to clarify the clinical benefit of an opioid-based pain control program for head and neck cancer patients during chemoradiotherapy. Patients and methods: Head and neck cancer patients who were to receive definitive or postoperative chemoradiotherapy were enrolled. The opioid-based pain control program consisted of a three-step ladder, with basic regimens of: Step 1: acetaminophen at 500–1000 mg three times a day. Step 2: fast-acting morphine at 5 mg three times a day before meals for a single day. Step 3: long-acting morphine administered around-the-clock, with a starting dosage of 20 mg/day and no upper limit set in principle. The primary endpoint of this study was compliance with radiotherapy. Results: A total of 101 patients from 10 institutions were registered between February 2008 and May 2009 and included in the analysis. The major combination chemotherapy regimen was cisplatin alone (76%). The rate of completion of radiotherapy was 99% and the rate of unplanned breaks in radiotherapy was 13% (13/101, 90% confidence interval: 9.9–16.5%). Median maximum quantity of morphine used per day was 35 mg (range 0–150 mg). Conclusions: Use of a systematic pain control program may improve compliance with CRT.

    Three patients who developed hypothyroidism after x irradiation to the neck are presented. The first two cases demonstrate that patients can develop clinical and chemical hypothyroidism after a very short interval following radiotherapy. Hypothyroidism developed in the first patient in the absence of surgical manipulation of the neck, or a large iodine load 4 months after receiving 6800 rad of x-ray therapy to his neck for carcinoma of the larynx. The second patient developed hypothyroidism approximately 6 months after his radiotherapy for carcinoma of the esophagus. Both of these patients demonstrated high titers of serum antithyroid antibodies. A third patient with Hodgkin's disease did not manifest clinical symptoms and signs of hypothyroidism until 6 years after radiation therapy. These cases demonstrate the variability of onset of hypothyroidism after radiotherapy and emphasize the need for careful evaluation of thyroid function before and after neck irradiation

    Exposure to excess gastric acid resulting from gastroesophageal reflux disease, also known as acid reflux or heartburn, might contribute to initiation of head and neck squamous cell carcinoma, particularly laryngeal cancer. Prior epidemiologic studies have reported inconsistent results. We sought to clarify this relationship using an observational study with a larger available sample size and better-characterized exposure information than most prior studies. A population-based case-control study of head and neck cancer in North Carolina with 1,340 newly diagnosed cases and 1,378 controls matched on age, race, and sex. We used unconditional logistic regression to examine associations between self-reported heartburn and development of overall head and neck cancer as well as development of cancer at specific tumor sites. Subgroup analysis by smoking and alcoholic drinking status was used to make comparisons with a previous study that used a similar study design. Overall, an increased odds of head and neck cancer was not associated with either self-reported history of heartburn symptoms (odds ratio = 0.85; 95% confidence interval 0.68, 1.06) or self-reported medical diagnosis of GERD (OR = 0.89; 95% CI 0.71, 1.11). These patterns held for specific tumor sites. For laryngopharyngeal cancer, we did not detect any associations regardless of joint smoking and alcoholic drinking status. Gastroesophageal reflux does not appear to play a role in development of head and neck cancer. 3b.

    57 Co-Bleomycin ( 57 Co-BLM) was used to visualize malignancies of the head and neck because it does not present the disadvantages of many other radiopharmaceuticals. In a series of 21 patients with 9 control subjects and 12 cases of tumors, 57 Co-BLM showed a high and rapid uptake in primary site and metastases of malignant tumors of various histologic types, but not in benign tumors such as angiofibromas. Compared to 67 Ga-citrate, 57 Co-BLM has many advantages for tumor imaging in the areas of nose, pharynx and larynx: No background activity due to the concentration of 57 Co-BLM in normal structures of the head and neck has ever been observed, as opposed to what happens with 67 Ga-citrate. Furthermore, the blood clearance of 57 Co-BLM is much more rapid than that of 67 Ga-citrate, so that an early study may be performed in a 6 to 24 hr interval instead of 48 to 72 hr with 67 Ga-citrate. 57 Co-BLM scintigraphy is an easy, non-invasive and sensible diagnostic technique in determining the extent of malignant tumors in ORL patients

    To determine whether 3 months of neck-specific exercises (NSEs) could benefit individuals with chronic whiplash-associated disorder (WAD) who were on a waiting list (WL) for treatment. A prospective, randomized controlled study. Primary health care. Individuals (N=41; 31 women, 10 men; mean age ± SD, 38±11.2y) with chronic (6-36mo) WAD, grades 2 and 3, were analyzed. Patients were randomly assigned to NSEs or no treatment for 3 months. Neck-specific disability (Neck Disability Index [NDI]), neck pain (visual analog scale), general pain-related disability (Pain Disability Index [PDI]), self-perceived performance ability (Self-Efficacy Scale [SES]), and health-related quality of life (EuroQol 5 dimensions [EQ-5D]) were measured. NSEs significantly improved the NDI, SES, and EQ-5D compared with WL (P<.01). There was significant improvement (P<.0001) over time in all outcomes for NSEs, and apart from the PDI, significant worsening (P=.002-.0002) over time for the untreated group. NSEs were more beneficial than no intervention while on a WL for individuals with chronic WAD. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    The management of anesthesia used in the plastic reconstruction of 18 cases of radiation injury of neck is reported. 17 cases were malignant tumor patients. After radiotherapy, their general condition was weak. The injury of neck skin and surrounding tissues was severe. Most operations were excision of the focus and repairing the wound using adjacent flap. The choice of anesthesia depended on the general condition, degree of injury and the procedure. Good pre-operative preparation, close monitoring and satisfactory airway control during operation are very important

    To determine the effectiveness of Pilates and yoga group exercise interventions for individuals with chronic neck pain (CNP). Quasi-randomised parallel controlled study. Community, university and private practice settings in four locations. Fifty-six individuals with CNP scoring ≥3/10 on the numeric pain rating scale for >3 months (controls n=17, Pilates n=20, yoga n=19). Exercise participants completed 12 small-group sessions with modifications and progressions supervised by a physiotherapist. The primary outcome measure was the Neck Disability Index (NDI). Secondary outcomes were pain ratings, range of movement and postural measurements collected at baseline, 6 weeks and 12 weeks. Follow-up was performed 6 weeks after completion of the exercise classes (Week 18). NDI decreased significantly in the Pilates {baseline: 11.1 [standard deviation (SD) 4.3] vs Week 12: 6.8 (SD 4.3); mean difference -4.3 (95% confidence interval -1.64 to -6.7); PPilates and yoga group exercise interventions with appropriate modifications and supervision were safe and equally effective for decreasing disability and pain compared with the control group for individuals with mild-to-moderate CNP. Physiotherapists may consider including these approaches in a plan of care. ClinicalTrials.gov NCT01999283. Copyright © 2015 Chartered Society of Physiotherapy. Published by Elsevier Ltd.

    Full Text Available The peri - operative management of post - burn contractures of the neck is a challenge not only to the surgeon but also the anaesthesiologist. A proper co - ordination between them is needed for providing a hassle - free patient care. This is a prospective study done on 30 consecutive patients of post burn contractures of the neck to compare the surgeon’s assessment of the type and pattern of post - burn contracture of the neck and the anaesthesiologist’s assessment of the airway. T he association of this with the peri - operative management of patients was also studied. The data analysed was type of contracture , mento - sternal distance , and preoperative grading of the airway. The method of securing intra - operative airway was documented . A direct co - relation was noted between the type of contracture with the Mallampatti grading of the airway and the sterno - mental distance. All type III contractures required release before intubation. In conclusion , it is advisable for the surgeon to be w ell - versed with the anaesthesiologist’s assessment of the airway and the anaesthesiologist to aware of the types of neck contracture in order to properly plan and execute the peri - operative management of these patients.

  3. A novel method for neck coordination exercise – a pilot study on persons with chronic non-specific neck pain

    Full Text Available Abstract Background Chronic neck pain is a common problem and is often associated with changes in sensorimotor functions, such as reduced proprioceptive acuity of the neck, altered coordination of the cervical muscles, and increased postural sway. In line with these findings there are studies supporting the efficacy of exercises targeting different aspects of sensorimotor function, for example training aimed at improving proprioception and muscle coordination. To further develop this type of exercises we have designed a novel device and method for neck coordination training. The aim of the study was to investigate the clinical applicability of the method and to obtain indications of preliminary effects on sensorimotor functions, symptoms and self-rated characteristics in non-specific chronic neck pain Methods The study was designed as an uncontrolled clinical trial including fourteen subjects with chronic non-specific neck pain. A new device was designed to allow for an open skills task with adjustable difficulty. With visual feedback, subjects had to control the movement of a metal ball on a flat surface with a rim strapped on the subjects' head. Eight training sessions were performed over a four week period. Skill acquisition was measured throughout the intervention period. After intervention subjects were interviewed about their experience of the exercise and pain and sensorimotor functions, including the fast and slow components of postural sway and jerkiness-, range-, position sense-, movement time- and velocity of cervical rotation, were measured. At six-month follow up, self-rated pain, health and functioning was collected. Results The subjects improved their skill to perform the exercise and were overall positive to the method. No residual negative side-effects due to the exercise were reported. After intervention the fast component of postural sway (p = 0.019 and jerkiness of cervical rotation (p = 0.032 were reduced.

    Spinal pain in the paediatric population is a significant health issue, with an increasing prevalence as they age. Paediatric patients attend for chiropractor care for spinal pain, yet, there is a paucity of quality evidence to guide the practitioner with respect to appropriate care planning. A retrospective chart review was used to describe chiropractic management of paediatric neck pain. Two researchers abstracted data from 50 clinical files that met inclusion criteria from a general practice chiropractic office in the Greater Toronto Area, Canada. Data were entered into SPSS 15 and descriptively analyzed. Fifty paediatric neck pain patient files were analysed. Patients' age ranged between 6 and 18 years (mean 13 years). Most (98%) were diagnosed with Grade I-II mechanical neck pain. Treatment frequency averaged 5 visits over 19 days; with spinal manipulative therapy used in 96% of patients. Significant improvement was recorded in 96% of the files. No adverse events were documented. Paediatric mechanical neck pain appears to be successfully managed by chiropractic care. Spinal manipulative therapy appears to benefit paediatric mechanical neck pain resulting from day-today activities with no reported serious adverse events. Results can be used to inform clinical trials assessing effectiveness of manual therapy in managing paediatric mechanical neck pain.

    Femoral neck fractures in the elderly comprise a significant number of orthopedic surgical cases at a major trauma center. These patients are immediately incapacitated, and surgical fixation can help increase mobility, restore independence, and reduce morbidity and mortality. However, operative treatment carries its own inherent risks including infections, deep vein thromboses, and intraoperative cardiovascular collapse. Cerebrovascular stroke is a relatively uncommon occurrence after hip fractures. We present 2 cases with unusual postoperative medical complication after cemented hip hemiarthroplasty for femoral neck fracture that will serve to illustrate an infrequent but very serious complication. Case 1 was a 73-year-old man with a Garden IV femoral neck fracture who underwent a right hip unipolar cemented hemiarthroplasty under general anesthesia. After uneventful surgery, he developed neurological deficits, and a postoperative noncontrast head computed tomography showed a right medial thalamic infarct. Case 2 was an 82-year-old man with a Garden IV femoral neck fracture who underwent a right hip unipolar cemented hemiarthroplasty under general anesthesia. After uneventful surgery, the patient became hemodynamically unstable. A postoperative noncontrast head computed tomography showed a large evolving left middle cerebral artery stroke. General anesthesia in the setting of decreased cardiac function (decreased ejection fraction and output) carries the risk for ischemic injury to the brain from decreased cerebral perfusion. Risk factors including advanced age, history of coronary artery disease, atherosclerotic disease, and atrial fibrillation increase the risk for perioperative stroke. Furthermore, it is known that during the cementing of implants, microemboli can be released, which must be considered in patients with preoperative heart disease. As a result, consideration of using a noncemented implant or cementing without pressurizing in this clinical scenario

    Objective: To study the imaging appearance of deep neck space cellulitis and abscess and to evaluate the diagnostic criteria of deep neck space infection. Methods: CT and MRI findings of 28 cases with deep neck space infection proved by clinical manifestation and pathology were analyzed, including 11 cases of retropharyngeal space, 5 cases of parapharyngeal space infection, 4 cases of masticator space infection, and 8 cases of multi-space infection. Results: CT and MRI could display the swelling of the soft tissues and displacement, reduction, or disappearance of lipoid space in the cellulitis. In inflammatory tissues, MRI imaging demonstrated hypointense or isointense signal on T 1 WI, and hyperintense signal changes on T 2 WI. In abscess, CT could display hypodensity in the center and boundary enhancement of the abscess. MRI could display obvious hyperintense signal on T 2 WI and boundary enhancement. Conclusion: CT and MRI could provide useful information for deep neck space cellulitis and abscess

    After age 60 hip fracture risk strongly increases, but only a fifth of this increase is attributable to reduced mineral density (BMD, measured clinically). Changes in bone quality, specifically bone composition as measured by Fourier Transform Infrared spectroscopic imaging (FTIRI), also contribute to fracture risk. Here, FTIRI was applied to study the femoral neck and provide spatially derived information on its mineral and matrix properties in age-matched fractured and non-fractured bones. Whole femoral neck cross sections, divided into quadrants along the neck’s axis, from 10 women with hip fracture and 10 cadaveric controls were studied using FTIRI and micro-computed Tomography. Although 3-dimensional micro-CT bone mineral densities were similar, the mineral-to-matrix ratio was reduced in the cases of hip fracture, confirming previous reports. New findings were that the FTIRI microscopic variation (heterogeneity) of the mineral-to-matrix ratio was substantially reduced in the fracture group as was the heterogeneity of the carbonate-to-phosphate ratio. Conversely, the heterogeneity of crystallinity was increased. Increased variation of crystallinity was statistically associated with reduced variation of the carbonate-to-phosphate ratio. Anatomical variation in these properties between the different femoral neck quadrants was reduced in the fracture group compared to controls. While our treatment-naïve patients had reduced rather than increased bending resistance, these changes in heterogeneity associated with hip fracture are in another way comparable to the effects of experimental bisphosphonate therapy, which decreases heterogeneity and other indicators of bone’s toughness as a material.

    Purpose: To examine the patterns of failure in patients treated with intensity-modulated radiotherapy (IMRT) for head-and-neck rhabdomyosarcoma (RMS). Methods and Materials: Between 1998 and 2005, 19 patients with a diagnosis of head-and-neck RMS received IMRT at The Methodist Hospital. There were 11 male and 8 female patients, with a median age of 6 years at time of irradiation. Tumor location was parameningeal in 7, orbital in 6, and other head-and-neck RMS in 6. Chemotherapy was given to all patients, with vincristine, actinomycin D, and cyclophosphamide being the most common regimen (n = 18). The median prescribed dose was 5040 cGy. The clinical target volume included the gross tumor volume with a 1.5-cm margin. The median duration of follow-up for surviving patients was 56 months. Results: The 4-year overall survival and local control rates were 76% and 92.9%, respectively. One patient developed a local failure in the high-dose region of the radiation field; there were no marginal failures. Distant metastasis was seen in 4 patients. Overall survival was 42.9% for parameningeal sites and 100% for other sites (p < 0.01). Late toxicities were seen in 7 patients. Two secondary malignancies occurred in 1 child with embryonal RMS of the face and a p53 mutation. Conclusions: Local control was excellent in patients receiving IMRT for head-and-neck RMS. Patterns of local failure reveal no marginal failures in this group of patients

    Full Text Available OBJECTIVE: Selecting controls is one of the most difficult tasks in the design of case-control studies. Hospital controls may be inadequate and random controls drawn from the base population may be unavailable. The aim was to assess the use of hospital visitors as controls in a case-control study on the association of organochlorinated compounds and other risk factors for breast cancer conducted in the main hospital of the "Instituto Nacional de Câncer" -- INCA (National Cancer Institute in Rio de Janeiro (Brazil. METHODS: The study included 177 incident cases and 377 controls recruited among female visitors. Three different models of control group composition were compared: Model 1, with all selected visitors; Model 2, excluding women visiting relatives with breast cancer; and Model 3, excluding all women visiting relatives with any type of cancer. Odds ratios (OR and 95% confidence intervals were calculated to test the associations. RESULTS: Age-adjusted OR for breast cancer associated with risk factors other than family history of cancer, except smoking and breast size, were similar in the three models. Regarding family history of all cancers, except for breast cancer, there was a decreased risk in Models 1 and 2, while in Model 3 there was an increased risk, but not statistically significant. Family history of breast cancer was a risk factor in Models 2 and 3, but no association was found in Model 1. In multivariate analysis a significant risk of breast cancer was found when there was a family history of breast cancer in Models 2 and 3 but not in Model 1. CONCLUSIONS: These results indicate that while investigating risk factors unrelated to family history of cancer, the use of hospital visitors as controls may be a valid and feasible alternative.

A poor level of knowledge and awareness among the public of Head & Neck Cancer, is an important consideration in the often delayed presentation for medical attention in many of these cases. Our study surveyed 200 members of the public to assess their knowledge and awareness of Head & Neck Cancer. One hundred and forty (70%) of respondents had never encountered the term "Head & Neck Cancer". One hundred and forty six (73%) failed to identify excessive alcohol consumption as a risk factor. Less than 100 (50%) would have concern about persisting hoarseness or a prolonged oral ulcer. An urgent need exists to raise awareness of Head & Neck Cancer among the public in Ireland.

  11. Morbidity after neck dissection in head and neck cancer patients : a study describing shoulder and neck complaints, and quality of life

    Background and purpose: up to 10% of all neck lymph node metastases present without a known primary site. The optimal treatment strategy for these patients is still undefined. The purpose of this retrospective analysis is to assess the outcome in patients with neck metastases from an unknown primary tumor (CUP). Furthermore, prognostic factors and treatment modalities are discussed. Patients and methods: from 1984 to 2003, 28 patients with squamous cell neck metastases from a CUP were treated at the authors' institution. In 17 patients, neck dissection (twelve radical, five modified radical) was performed. In that case, adjuvant radiotherapy was carried out with a mean of 56.7 Gy. In eleven patients, only biopsies were done. These patients received definitive radiotherapy with a mean of 66.8 Gy. In summary, 25 patients received extended radiotherapy including both sides of the neck and potential mucosal primary sites. Additional chemotherapy was administered to five patients. Results: the duration of follow-up was 4.1-189.5 months (median 45.1 months). After this period of time, ten patients (36%) remained alive. 5-year overall survival was 40.1%, neck control rate 72.7%. No subsequent primary could be detected. Extracapsular extension and surgery had significant influence on prognosis. Grade 3 toxicity (mucositis or skin reactions) was seen in three patients; no hematologic toxicity > grade 2 was observed. 19 patients suffered from grade 2 xerostomia. Conclusion: with radical surgery followed by radiotherapy good survival rates in patients with neck metastases from a CUP can be obtained. Whether limited radiotherapy might be equal to extended irradiation and can reduce side effects, must be shown in ongoing clinical trials. (orig.)

    We analyzed 15 cases of head and neck cancer (13 out of 15 were squqmous cell cancer.) by Southern blotting to identify the possible tumor suppressor gene. Firstly we searched the chromosome 17p with pYNZ22, pMCT35.1 and p144D6. 5 out of 7 informative cases showed loss of heterozygosity implying the loss of tumor suppressor gene near those loci. Afterwards analysis of these 5 cases is needed to identify the presence of tumor suppressor genes and the oncogenetic mechanism. (Author)

    Between 1967 and 1988, 102 patients with Stage T1-2N0 squamous cell carcinoma of the tongue were treated with uneven fractional irradiation therapy (intra-oral electron beam irradiation with and without prophylactic ipsilateral upper neck irradiation at the Dept. of Radiology, Nihon University School of Medicine. Of 102 primary lesions, 89 cases were controlled with this therapy. In this study, these 89 cases were investigated in order to analyze the prophylactic effect of upper neck irradiation. Of the 89 patients, 42 received only intra-oral electron beam irradiation, while the remaining 47 received a combination of intra-oral electron beam irradiation and prophylactic irradiation to the ipsilateral upper neck. Twenty three of the 89 (25.8%) developed metastasis to the neck after the radiotherapy. A breakdown of these 23 cases reveals that 3/21 (14.3%) received 40-50 Gy to the neck, 9/26 (34.6%) received 20-40 Gy to the neck, and 11/42 (26.2%) received no irradiation to the neck (p<0.05 between first and second groups, and between first and third groups). The neck metastasis was classified into one of three categories based on the region in which it first appeared (ipsilateral upper neck, ipsilateral lower neck or contralateral neck). The first metastasis was seen in the ipsilateral upper neck, in the ipsilateral lower neck and in the contralateral neck in 17, 4 and 2 patients, respectively. In 1/19 who had received 40-50 Gy, in 5/21 who had received 20-40 Gy and in 11/42 who had not received neck irradiation the first metastasis appeared in the ipsilateral upper neck. The five year survival rate was 94%, 75% and 85% in the patients receiving 40-50 Gy, 20-40 Gy and no neck irradiation, respectively. These results suggest that prophylactic irradiation of 40-50 Gy to the ipsilateral upper neck might decrease the incidence of neck metastasis and slightly prolong survival time. (author)

    Full Text Available The impact of ablative oral cancer surgery was studied, with reference to recurrence and nodal metastasis,  survival probability and prognostic indicators and to determine if ethnicity influences the survival of patients. Patients who underwent major ablative surgery of the head and neck region with neck dissection were identified and assessed. Those with stage I-IV oral and oropharyngeal malignancies necessitating resection with or without radiotherapy from 2004 to 2009 were included in this study. All individuals had a pre-operative assessment and post operative assessment. Survival distributions were analyzed using Kaplan-Meier curves. Eighty seven patients (males: 38%; females: 62% were included in this study, with an age range of 21-85 years. Some 78% underwent neck dissections while 63% had surgery and radiotherapy. Nodal and primary site recurrence was 5.7% and 20.5%. The median survival time was 57 months. One year Overall Survival (OS rate was 72.7% and three year overall survival rate 61.5%. The log-rank test showed a significant difference of survival between Malay and Chinese patients (Bonferroni correction p=0.033. Recurrence-Free Survival (RFS analysis revealed that 25% of the patients have reached the event of recurrence at 46 months. The three year survival rate was 76.1%. In the RFS analysis, the log-rank test showed a significant difference in the event of recurrence and nodal metastasis (p<0.001. Conservative neck effectively controls neck metastases.

    Purpose: Current methods to clinically define head and neck tumor bulk are qualitative and imprecise. Although the American Joint Committee on Cancer (AJCC) staging system is important for this purpose, limitations exist. This study will investigate the prognostic value of computed tomography (CT) derived tumor volume measurements in comparison to AJCC stage and other significant variables. Materials and Methods: Seventy-six patients with advanced head and neck squamous cell carcinoma were treated with concomitant boost accelerated superfractionated irradiation. Doses ranged from 68.4-73.8 Gy (median 70.2 Gy). Good quality pretherapy CT scans were available in 51 patients. Total tumor volume (TTV) estimates were derived from these scans using digital integration of primary tumor and metastatic lymphadenopathy. Actuarial and multivariate statistical techniques were applied to analyze local control. Results: Thirty-six-month local control was 63%. TTV ranged from 5-196 cm{sup 3} (median 35 cm{sup 3}) for all cases, 5-142 cm{sup 3} (median 17 cm{sup 3}) for those controlled, and 16-196 cm{sup 3} (median 47 cm{sup 3}) for local failures. There was a significant increase in failures above 35 cm{sup 3}. Univariate analysis found that TTV, T-stage, N-stage, and primary site were each significant prognostic variables. Local control for TTV {<=}35 cm{sup 3} was 92% at 36 months vs. 34% for TTV >35 cm{sup 3} (p = 0.0001). Multivariate analysis, however, found that TTV, primary site, and sex were important as independent variables; T and N stage were not independently significant unless TTV was removed from the model. Conclusions: This study demonstrates the prognostic significance of TTV in advanced carcinoma of the head and neck. This variable appears to be a more predictive than AJCC clinical stage. Quantitative tumor volume measurements may prove to be a useful parameter in future analyses of head and neck cancer.

    2012-01-01

    Background: This analysis was undertaken to assess the need for planned neck dissection in patients with a complete response (CR) of involved nodes after irradiation and to determine the benefit of a neck dissection in those with less than CR by tumor site. Methods: Our cohort included 880 patients with T1-4, N1-3M0 squamous cell carcinoma of the oropharynx, larynx, or hypopharynx who received treatment between 1994 and 2004. Survival curves were calculated by the Kaplan-Meier Method, comparisons of rates with the log–rank test and prognostic factors by Cox's proportional hazard model. Results: Nodal CR occurred in 377 (43%) patients, of whom 365 patients did not undergo nodal dissection. The 5-year actuarial regional control rate of patients with CR was 92%. Two hundred sixty-eight of the remaining patients (53%) underwent neck dissections. The 5-year actuarial regional control rate for patients without a CR was 84%. Those who had a neck dissection fared better with 5-year actuarial regional control rates of 90% and 76% for those operated and those not operated (p < 0.001). Variables associated with poorer regional control rates included higher T and N stage, non-oropharynx cancers, non-CR, both clinical and pathological. Conclusions: With 92% 5-year neck control rate without neck dissection after CR, there is little justification for systematic neck dissection. The addition of a neck dissection resulted in higher neck control after partial response though patients with viable tumor on pathology specimens had poorer outcomes. The identification of that subgroup that benefits from additional treatment remains a challenge.

    As to healing process and prognosis of femoral neck fracture, radionuclide bone scintigraphy using sup(99m)Tc phosphorus compound was performed and the following results were obtained. 1. In cases of osteosynthesis, scintigraphical study showed a certain serial pattern until fracture was uneventfully healed. 2. On the other hand, in cases with non-union or late segmental collapse of the head, scintigraphy revealed defect at superolateral or central area in the head. This finding could be already noted prior to roentgenographical evaluation. 3. In the study of radionuclide uptake count on the femoral head of resected specimen, the higher value was observed in the area along medial fracture edge to medial margin of the head. Histological study showed feature of increased new bone formation at the area of higher radionuclide uptake. Vascular supply through the bone marrow of the neck and superior retinacular artery was thought to play an important role for the new bone formation. 4. From the aforementioned results, sup(99m)Tc phosphorus compound scintigraphy was considered as one of the quite useful methods for early diagnosis of complications after femoral neck fracture.

    2015-09-01

    Full Text Available The purpose of this study is to assess the beneficial effects of a far-infrared-emitting collar (FIRC on the management of neck disorders. A neck disorder is generalized as neck muscle pain and its relative mental disorders because the etiologies of the neck’s multidimensional syndrome are either muscle impairment or psychiatric distress. This is the first study to determine the efficacy of a FIRC by evaluating objective physical evidence and psychometric self-reports using a parallel-arm randomized sham-controlled and single-blinded design. In this trial, 60 participants with neck disorders were observed at baseline and post-intervention. Compared to the placebo group after a 30-min intervention, the FIRC demonstrated a statistically significant biological effect in elevating skin temperature and promoting blood circulation with p-values 0.003 and 0.020, respectively. In addition, FIRC application significantly reduced neck muscle tension, relieved pain, ameliorated fatigue, improved depression, and decreased anxiety. The FIRC could therefore be a potential treatment for neck disorders.

    Summary Background Claims in the medical literature suggest that neck fullness and witnessed neck pulsations are useful in the diagnosis of typical AV nodal reentrant tachycardia (AVNRT). Hypothesis Neck fullness and witnessed neck pulsations have a high positive predictive value in the diagnosis of typical AVNRT. Methods We performed a cross sectional study of consecutive patients with palpitations presenting to a single electrophysiology (EP) laboratory over a 1 year period. Each patient underwent a standard questionnaire regarding neck fullness and/or witnessed neck pulsations during their palpitations. The reference standard for diagnosis was determined by electrocardiogram and invasive EP studies. Results Comparing typical AVNRT to atrial fibrillation (AF) or atrial flutter (AFL) patients, the proportions with neck fullness and witnessed neck pulsations did not significantly differ: in the best case scenario (using the upper end of the 95% confidence interval [CI]), none of the positive or negative predictive values exceeded 79%. After restricting the population to those with supraventricular tachycardia other than AF or AFL (SVT), neck fullness again exhibited poor test characteristics; however, witnessed neck pulsations exhibited a specificity of 97% (95% CI 90–100%) and a positive predictive value of 83% (95% CI 52–98%). After adjustment for potential confounders, SVT patients with witnessed neck pulsations had a 7 fold greater odds of having typical AVNRT, p=0.029. Conclusions Although neither neck fullness nor witnessed neck pulsations are useful in distinguishing typical AVNRT from AF or AFL, witnessed neck pulsations are specific for the presence of typical AVNRT among those with SVT.

    Full Text Available Background. Fibromuscular dysplasia (FMD is a vascular disease that may present as aneurysms in the cervical arteries. Spontaneous neck hematoma is a rare life threatening medical condition. This is the first report of neck hematoma in a patient with FMD. Methods and Results. We present a case of a 69-year-old woman, with diagnosed cervical FMD and a 3-day history of sore throat and neck pain, who presented with enlarging neck hematoma. No active bleeding was noticed on CT angiography, airway was not compromised, and patient was managed conservatively. Next day, invasive angiography was performed, and no bleeding vessel was demonstrated. Patient has improved and was discharged after 5 days of hospitalization. We have discussed the different etiology of this condition, focusing on systemic vascular diseases. Conclusion. Complaint of neck pain in a patient with a FMD should raise suspicion for possible neck hematoma. Conversely, spontaneous neck hematoma without clear etiology should raise suspicion for a systemic vascular disease.

    PURPOSE: The objective of this study is to investigate the effect of three different workplace interventions on long-term compliance, muscle strength gains, and neck/shoulder pain in office workers. METHODS: A 1-yr randomized controlled intervention trial was done with three groups: specific...... resistance training (SRT, n = 180), all-round physical exercise (APE, n = 187), and reference intervention (REF, n = 182) with general health counseling. Physical tests were performed and questionnaires answered at pre-, mid-, and postintervention. The main outcome measures were compliance, changes......: Compliance was highest in SRT but generally decreased over time. SRT and APE caused increased shoulder elevation strength, were more effective than REF to decrease neck pain among those with symptoms at baseline, and prevent development of shoulder pain in those without symptoms at baseline....

    Calcification of the yellow ligament sometimes compresses the spinal cord and can induce myelopathy. Usually, the calcification does not induce acute neck pain. We report a case of a patient with acute neck pain caused by calcium pyrophosphate dihydrate in a calcified cervical yellow ligament. A 70-year-old Japanese woman presented with acute neck pain. She had a moderately high fever (37.5 °C), and her neck pain was so severe that she could not move her neck in any direction. Computed tomography showed a high-density area between the C5 and C6 laminae suspicious for calcification of the yellow ligament. Magnetic resonance imaging showed intermediate-signal intensity on T1-weighted imaging and high-signal intensity on T2-weighted imaging surrounding a low-signal region on both T1- and T2-weighted imaging with cord compression. There was a turbid, yellow fluid collection in the yellow ligament at the time of operation. Histologically, calcium pyrophosphate dihydrate crystals were found in the fluid, and she was diagnosed as having a pseudogout attack of the yellow ligament. Pseudogout attack of the cervical yellow ligament is rare, but this clinical entity should be added to the differential diagnosis of acute neck pain, especially when calcification of the yellow ligament exists.

    Conclusion: Paragangliomas of the head and neck are uncommon lesions. The most common site in the head and neck region was the jugulotympanic region. Most cases of jugulotympanic paraganglioma presented in the fifth decade and later. Laryngeal paraganglioma presented clinically earlier in the second decade. Jugulotympanic and laryngeal paraganglioma showed dominance of tumor vasculature histologically. There was a rare case of laryngeal paraganglioma with lateral neck extension in this study.

    1994-01-01

    The neck-tongue syndrome, consisting of pain in the neck and altered sensation in the ipsilateral half of the tongue aggravated by neck movement, has been attributed to damage to lingual afferent fibres travelling in the hypoglossal nerve to the C2 spinal roots. The lingual afferents in the hypoglossal nerve are thought to be proprioceptive. Two further cases of the neck-tongue syndrome are described, the spectrum of its clinical manifestations is explored, and the phenomenon of lingual pseudoathetosis is illustrated as a result of the presumed lingual deafferentation.

    DC-SIGN is a C-type lectin receptor of dendritic cells and is involved in the early stages of numerous infectious diseases. DC-SIGN is organized into a tetramer enabling multivalent interaction with pathogens. Once formed, the DC-SIGN-pathogen complex can be internalized into compartments of increasing acidity. We have studied the pH dependence of the oligomerization state and conformation of the entire extracellular domain and neck region. We present evidence for equilibrium between the monomeric and tetrameric states of the extracellular domain, which exhibits a marked dependence with respect to both pH and ionic strength. Using solution x-ray scattering we have obtained a molecular envelope of the extracellular domain in which a model has been built. Our results highlight the central role of the neck domain in the pH-sensitive control of the oligomerization state, in the extended conformation of the protein, and in carbohydrate recognition domain organization and presentation. This work opens new insight into the molecular mechanism of ligand release and points to new avenues to block the first step of this important infection pathway.

    1977-01-01

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

    2014-01-01

    Full Text Available The aim of the study is to analyze all completely excised BCCs in the head and neck region with regard to age, sex, personal and familial history, skin type, tumor localization and size, histopathological subtype of tumor, reconstruction method, and recurrence rates. Incompletely excised BCCs were not included in this study since incomplete excision is the most important preventable risk factor for recurrence. In 320 patients, 331 lesions were retrospectively evaluated by dividing into the following 8 subunits: scalp, frontotemporal, orbital, nose, cheek, auricula, perioral, and chin-neck area. Most of the patients were in 60–70 age group (34.7%. The nose (32.3% was the most common site of presentation. Clinically, all lesions and, histopathologically, most of the lesions (42.2% presented were of the nodular type. All cases of recurrence after complete excision (n=9, 2.7% were located in the median parts of the head and neck region and were mainly diagnosed histopathologically as sclerotic and micronodular. Even though completely excised, head and neck region BCCs, especially which are more prone to recurrence due to anatomical and histopathological properties, should be more closely monitored in order to decrease morbidity and health care costs.

  11. Neck lift my way: an update.

    2014-12-01

    The author updates prior descriptions of an approach to the surgical neck lift that aims for a maximum degree of control over the size, shape, and position of every anatomical feature of the neck that is negatively affecting its appearance. A 38-year clinical experience guided the development of the operative tactics that define the strategy. Data collected from a records review of 522 consecutive neck lifts performed during the 10-year period 2004 through 2013 further inform the report. The approach has eight features: (1) nearly routine use of open submental access to all tissue layers of the central neck, including a regimen that curbed the problems that may attend an extensive tissue dissection; (2) management of lax neck skin by lateral excision using a specific postauricular incision, or by using the nonexcisional method of redistribution; (3) open lipectomy for precise removal of excess subcutaneous neck and jawline fat; (4) individualized modifications to subplatysmal fat, perihyoid fascia, and anterior digastric muscles; (5) treatment of large, ptotic, or malpositioned submandibular salivary glands by partial excision using a transcutaneous traction suture; (6) the current version of the corset platysmaplasty, which is used to treat static paramedian platysma muscle bands, and to avoid contour imperfections following subplatysmal maneuvers; (7) an approach that facilitates an isolated neck lift; and (8) durable results. Case examples demonstrate outcomes. Although the updated approach remains relatively complex and invasive, the author believes that the ends justify the means.

    Acute suppurative neck infections associated with third or fourth branchial arch fistulas are frequently recurrent. Third and fourth branchial arch anomalies are much less common than those of second arch and usually present with left thyroid lobe inflammation. The authors present their experience with 15 cases of pyriform sinus fistulae (PSF) of third branchial arch origin and 3 cases of fourth arch origin, all of which presented as recurrent neck infection mainly on the left side. A retrospective review of 18 cases of third and fourth arch fistulae treated at JIPMER from 2005 to 2010. This study includes 18 patients with PSF diagnosed by the existence of fistulous tract radiologically and intraoperatively with pathological correlation. Neck exploration with excision of tract and left hemithyroidectomy was performed in all cases. The patients consisted of 7 males and 11 females, and the ages ranged from 3 to 15 years. All of them presented with recurrent episodes of neck infection. Investigations performed include computed tomography (CT) fistulography, barium swallow and ultrasound which were useful in delineating pyriform sinus fistulous tract preoperatively. All cases were on the left side and the fistula was identified by barium swallow in 14 cases (80%), while intraoperative and pathologic confirmation of the tract was possible in all cases (100%). Neck exploration with an emphasis on complete exposure of the recurrent laryngeal nerve and exposure of the pyriform sinus opening to facilitate complete fistulous tract excision with left hemithyroidectomy was successful in all patients. A follow up period of 1-3 years showed no recurrence. Recurrent neck infection in a child should alert the physician to the possibility of an underlying pyriform sinus fistula of branchial origin and CT fistulography should be performed after the resolution of the neck infection to delineate the tract anatomically.

    2015-02-01

    Full Text Available Hydatid disease, also known as echinococcosis or hydatidosis , is an infectious disease caused by Echinococcus. Echinococcus granulosus is the most common Echinococcus species affecting human beings. It may affect any organ and tissue in the body, in particular the liver and lung. Musculoskeletal or soft tissue hyda tidosis accounts for about 0.5% 5% of all echinococcal infections in endemic areas, and is almost always secondary to the hepatic or pulmonary disease. Even in regions where echinococcosis is endemic, hydatidosis of cervicofacial region is extremely rare. Herein, we present exceptionally rare case in a 55 year old female with an unusual localization of primary multilocular hydatid cyst in the right supraclavicular region of the neck. A high index of suspicion is required to diagnose hydatid cyst in rare loc ations like this. Hydatid cyst should be considered in differential diagnosis of benign swellings of head and neck region, so that it can be managed during surgery to prevent acute anaphylaxis

The patient was a 55-year-old male with dysphagia who had undergone irradiation to the neck for a malignant lymphoma ten years previously. The dysphagia that had gradually worsened in ten years made him enable to eat and drink orally. He often contracted by pneumonia. On first examination, atrophic changes were observed in the soft palates, and the epiglottis, and the improvement of the tongue was bilaterally impaired. These findings were diagnosed as the causes of the dysphagia. A barium study showed that the movement of the tongue and the pharynx were impaired. The barium was aspirated. A plain X-ray film of the mandible showed ostitis. The impairment of the tongue movement was due to bilateral hypopharyngeal nerve palsies induced by the irradiation. Laryngeal suspension and cricopharyngeal myotomy were not suitable because they could have aggravated the radiation necrosis of the thyroid cartilage which will be expected in the future. A total laryngectomy, which sacrifies the phonation, was out of the question, because the patient's dysarthria was not so hard to understand. He was instructed in the self-insertion of a feeding tube to get enough nutrition, the physical therapy of the lung with the aid of his wife to prevent aspiration pneumonia. The loss of phonation lowers the QOL of such patients. In the cases with dysphagia which do not recover with surgical treatments, rehabilitation should mainly stress the conservation of phonation and the prevention of pneumonia to maintain the higher QOL of patients.

    Full Text Available Blunt cerebrovascular injury (BCVI to the carotid artery is a relatively rare injury that is difficult to identify even with imaging. Any symptoms or neurological deficits following blunt neck injury mandate evaluation and consideration of BCVI. In an effort to highlight this issue, we report the case of a 31-year-old male patient who presented with left-sided weakness consistent with transient ischemic attack (TIA and concussion. The patient’s symptoms occurred within 24 hours of a blunt neck injury sustained by a knee strike during a basketball game. An initial computerized tomography (CT scan of the brain was normal; a CT angiogram (CTA of the neck and carotids did not reveal obstruction, dissection, stenosis, or abnormalities of the carotid or vertebral vessels and the patient was subsequently discharged. A magnetic resonance imaging (MRI of the brain obtained four days after the initial injury demonstrated an acute infarct in the right middle cerebral artery (MCA territory. Thus, despite initial negative imaging, neurological deficits must be aggressively pursued in order to prevent stroke in BCVI cases.

    Glassey, J; Barone, A; Montague, G A; Sabou, V

    This chapter discusses the importance of modelling and control in increasing food process efficiency and ensuring product quality. Various approaches to both modelling and control in food processing are set in the context of the specific challenges in this industrial sector and latest developments in each area are discussed. Three industrial case studies are used to demonstrate the benefits of advanced measurement, modelling and control in food processes. The first case study illustrates the use of knowledge elicitation from expert operators in the process for the manufacture of potato chips (French fries) and the consequent improvements in process control to increase the consistency of the resulting product. The second case study highlights the economic benefits of tighter control of an important process parameter, moisture content, in potato crisp (chips) manufacture. The final case study describes the use of NIR spectroscopy in ensuring effective mixing of dry multicomponent mixtures and pastes. Practical implementation tips and infrastructure requirements are also discussed.

    It is proposed that altered scapular muscle function can contribute to abnormal loading of the cervical spine. However, it is not clear if patients with idiopathic neck pain show altered activity of the scapular muscles. The aim of this paper was to systematically review the literature regarding the differences or similarities in scapular muscle activity, measured by electromyography ( = EMG), between patients with chronic idiopathic neck pain compared to pain-free controls. Case-control (neck pain/healthy) studies investigating scapular muscle EMG activity (amplitude, timing and fatigue parameters) were searched in Pubmed and Web of Science. 25 articles were included in the systematic review. During rest and activities below shoulder height, no clear differences in mean Upper Trapezius ( = UT) EMG activity exist between patients with idiopathic neck pain and a healthy control group. During overhead activities, no conclusion for scapular EMG amplitude can be drawn as a large variation of results were reported. Adaptation strategies during overhead tasks are not the same between studies. Only one study investigated timing of the scapular muscles and found a delayed onset and shorter duration of the SA during elevation in patients with idiopathic neck pain. For scapular muscle fatigue, no definite conclusions can be made as a wide variation and conflicting results are reported. Further high quality EMG research on scapular muscles (broader than the UT) is necessary to understand/draw conclusions on how scapular muscles react in the presence of idiopathic neck pain.

    The influence of radiotherapy in advanced head and neck cancer was investigated by autopsy of head and neck patients who had had carotid artery rupture. Twenty-five cases of head and neck cancer revealed carotid artery rupture among the 255 head and neck cases autopsied from 1972 to 1985. The rate of carotid artery rupture in hypopharyngeal cancer was 8/32 (25%); in oral cancer 8/55 (14.5%), and in other cancers 9/165 (5.4%). In localization of ruptured arteries there were 9 cases of common carotid artery, 14 cases of external carotid artery, one case of internal carotid artery, and one unknown. These cases were irradiated using more than 70 Gy. The following reasons for carotid artery rupture were suspected: 1. There was a tumor with deep ulceration and necrosis near the vessel. 2. The wall of the artery had radiation angitis. 3. The artery wall was necrotic because of invasion by the tumor. 4. Thrombosis developed with ensuant rupture of the artery. Radiotherapy for advanced cancer of the head and neck is necessary to control pain and as palliative treatment, but to avoid rupture of the carotid artery, pain clinic techniques and chemotherapy as palliative treatment for this kinds of terminal condition should also be considered.

    The aim of this study was to determine the effectiveness of a multimodal treatment in the short and medium term for disability in nonspecific chronic neck pain. The design of this study is a single-blinded randomized controlled trial carried out in a university research laboratory. Forty-five patients between 18 and 65 yrs with nonspecific chronic neck pain were included in this study. Each patient was treated eight times over a 4-wk period. The sample was divided into three groups: control group, subjected to a protocol of manual therapy; experimental group 1, subjected to a protocol of manual therapy and therapeutic patient education; and experimental group 2, subjected to manual therapy, therapeutic patient education, and a therapeutic exercise protocol. Assessments were performed at baseline and at 4, 8, and 16 wks using the following measurements: the Neck Disability Index, the 11-item Tampa Scale of Kinesiophobia, the Fear Avoidance Beliefs Questionnaire, the Neck Flexor Muscle Endurance Test, and the Visual Analog Fatigue Scale. The nonparametric Kruskal-Wallis test for the Neck Disability Index showed statistically significant differences between baseline outcomes and all follow-up periods (P Kruskal-Wallis test, differences were found for the Visual Analog Fatigue Scale and the Neck Flexor Muscle Endurance Test in the follow-ups at 8 and 16 wks (P < 0.05). Analysis of variance for group × time interaction showed statistically significant changes (Tampa Scale of Kinesiophobia, F = 3.613, P = 0.005; Fear Avoidance Beliefs Questionnaire, F = 2.803, P = 0.022). Minimal detectable changes were obtained in both experimental groups for the 11-item Tampa Scale of Kinesiophobia but not in the control group. Differences between experimental groups and the control group were found in the short and medium term. A multimodal treatment is a good method for reducing disability in patients with nonspecific chronic neck pain in the short and medium term.

    Head and neck cancers account for an estimated 549,000 global cancer diagnoses each year. While tobacco use, alcohol consumption, and HPV16 infection are considered to be the major risk factors for this disease, occupational risk factors, including exposure to asbestos, have also been described, although dust exposures other than asbestos have been historically understudied. We have investigated the relationship between occupational exposures to five types of dusts, including sawdust, concrete dust, leather dust, metal dust, and chimney soot, and head and neck squamous cell carcinomas (HNSCC) in the greater Boston area. We report findings from a population-based case–control study involving 951 incident HNSCC cases and 1193 controls, frequency matched on age (±3 years), sex, and town/neighborhood of residence. Multivariable logistic regression was used to assess the association between occupational exposure to each type of dust and HNSCC, overall and by primary tumor site. After adjusting for age, sex, race, smoking, alcohol consumption, education, and HPV16 serology, laryngeal carcinoma risk increased for each decade of occupational exposure to sawdust (OR = 1.2, 95% CI: 1.0, 1.3) and metal dust (OR = 1.2, 95% CI: 1.0, 1.4); and HNSCC risk increased for each decade of occupational leather dust exposure (OR = 1.5, 95% CI: 1.2, 1.9). We have provided evidence for an association between occupational sawdust and metal dust and laryngeal squamous cell carcinoma, and leather dust and HNSCC, with increasing risk with longer duration at the exposed occupation

    Full Text Available Objectives The aim of this study was to determine risk factors associated with 30-day readmission for patients undergoing inpatient otolaryngologic head and neck surgery. Study Design Retrospective cohort study analysis. Setting Study at 2 tertiary hospitals. Methods A 10-year retrospective cohort analysis was performed for 30-day readmissions of otolaryngology surgical cases between July 1, 2006, and June 30, 2016, at Assir Central Hospital and Abha Private Hospital. Data included total number of patients, type of surgical procedure, number of and reasons for readmissions, and length of hospital stay. Results There were 32,662 discharges for otolaryngology operations over the 10-year period of the study, of which 364 patients were readmitted, giving a rate of 11.14 readmissions per 1000 operative procedures (95% CI, 10.1-12.3. The male:female ratio was 1.4:1. Period of postoperative stay ranged from 1 to 3 days and, after readmission, 2 to 5 days. The main reasons for readmission were bleeding in otolaryngologic cases and wound hematoma in head and neck surgical cases. Overall readmission rates dropped significantly from 12.72 per 1000 operative procedures in the first 5 years to 10.16 in the second 5 years. Conclusions This study helped to establish special policies and procedures to prevent readmission by utilizing best practices, including addressing quality care, using preadmission clinics, preventing surgical site infection, and improving communication with community physicians. Plans based on these results also include the development of national model for predicting readmission within 30 days of discharge.

    This study compared the relationship between some clinical factors and the size of neck flexors in participants with or without chronic neck pain. In this case-control study, the correlation between flexor endurance capacity as well as thickness, cross-section area, and shape ratio of longus colli/capitis and sternocleidomastoid muscles were examined in 30 patients with chronic neck pain and 30 asymptomatic participants. The patients showed lower flexor endurance (P = 0.02), smaller thickness (P = 0.03), and cross-section area (P pain. In the control group, flexor endurance was negatively correlated with longus colli shape ratio (r = -0.45, P = 0.01) but positively correlated with longus capitis thickness (r = 0.45, P = 0.01) and cross-section area (r = 0.38, P = 0.03). Neck disability and pain intensity indices were not significantly correlated with either flexor muscles endurance or size. The ultrasonographic measures of the deep neck flexor muscles and the flexor endurance test, being associated with each other, could successfully differentiate patients with chronic neck pain from asymptomatic participants. However, the endurance test scores were not correlated with self-reported disability or pain intensity indices.

    To learn about neck lacerations caused by skate blades in hockey. A retrospective Web-based survey and follow-up of registered USA Hockey players. Three hundred twenty-eight thousand eight hundred twenty-one of 457 038 registered USA Hockey players with a current e-mail address were contacted and invited to participate in the survey. Of 26 589 players (5.8% of all USA registered players) who responded to the survey, 247 were excluded due to incomplete data. Of 26 342 surveys analyzed, 23 199 respondents were men (88%), 3015 women (11.4%), and 128 (0.5%) did not designate gender. An original survey instrument was developed, formatted, and linked to a Mayo Clinic Web site. Neck lacerations from a skate blade, including mechanism, severity, treatment required, and the type of neck protector worn. Of the 26 342 respondents, 11 935 (45.4%) currently wear neck protection and 485 (1.8%) have sustained a neck laceration. When the laceration occurred, 132 of the players (27%) were wearing neck protection. Interviews with 33 injured players established that lacerations were superficial: 20 (61%) required bandaging only, 11 were sutured, and 2 were glued. Based on this survey, the currently available neck laceration protectors do not eliminate the risk of a neck laceration from a skate blade.

    Full Text Available Abstract Background A major problem with rehabilitation interventions for neck pain is that the condition may have multiple causes, thus a single treatment approach is seldom efficient. The present study protocol outlines a single blinded randomised controlled trial evaluating the effect of tailored treatment for neck-shoulder pain. The treatment is based on a decision model guided by standardized clinical assessment and functional tests with cut-off values. Our main hypothesis is that the tailored treatment has better short, intermediate and long-term effects than either non-tailored treatment or treatment-as-usual (TAU on pain and function. We sub-sequentially hypothesize that tailored and non-tailored treatment both have better effect than TAU. Methods/Design 120 working women with minimum six weeks of nonspecific neck-shoulder pain aged 20–65, are allocated by minimisation with the factors age, duration of pain, pain intensity and disability in to the groups tailored treatment (T, non-tailored treatment (NT or treatment-as-usual (TAU. Treatment is given to the groups T and NT for 11 weeks (27 sessions evenly distributed. An extensive presentation of the tests and treatment decision model is provided. The main treatment components are manual therapy, cranio-cervical flexion exercise and strength training, EMG-biofeedback training, treatment for cervicogenic headache, neck motor control training. A decision algorithm based on the baseline assessment determines the treatment components given to each participant of T- and NT-groups. Primary outcome measures are physical functioning (Neck Disability Index and average pain intensity last week (Numeric Rating Scale. Secondary outcomes are general improvement (Patient Global Impression of Change scale, symptoms (Profile Fitness Mapping neck questionnaire, capacity to work in the last 6 weeks (quality and quantity and pressure pain threshold of m. trapezius.

    Radiotherapy of head and neck malignancies is accompanied by oral discomforts, such as epithelitis, pain and functional impairment. This can lead to chronic sequalae with subjective distress such as loss of taste and xerostomia and pronounced decrease in quality of life. Thus, the need to reduce the mucosal damage following radiotherapy is obvious. Therefore, we investigated the possible ability of sucralfate, an aluminium hydroxide complex of sulphated sucrose used in the treatment of gastric ulcer, in preventing oral discomfort in patients treated with curative intent for malignancies in the head and neck region. The study was double-blind, placebo-controlled and randomized and included 50 consecutive patients. The study demonstrated that the proportion of patients with severe mucosal reactions was significantly lower in the sucralfate group than in the placebo group. (orig.)

    The aim of this study was to investigate the differences in cold pain threshold (CTh), pressure pain threshold (PPT), cold pain tolerance (CPTo) tests, and the level of self-efficacy when self-efficacy for diagnostic sensory testing was manipulated by verbal persuasion before a testing situation in persons with neck pain and in healthy controls. A randomized experimental design was used. Twenty-one healthy volunteers and 22 individuals with either traumatic or nontraumatic chronic neck pain were recruited to participate in the study. The intervention consisted of two experimental verbal persuasion conditions: Increase self-efficacy and Decrease self-efficacy. The PPT was measured using a pressure algometer, the CTh was measured using a thermo test system, and CPTo was measured by submerging the participant's hand in ice water up to the elbow joint. On three occasions, the participants reported their self-efficacy level in performing the sensory tests. In the chronic neck pain group, there were no differences in pain threshold or tolerance. There was a difference in the self-efficacy level after verbal persuasion between the experimental conditions. In the healthy control group, the CThs increased following the condition that aimed to increase self-efficacy. No other differences were observed in the healthy controls. A short verbal persuasion in the form of manipulative instructions seems to have a marginal effect on the individual's self-efficacy levels in the chronic neck pain group and a slight influence on the results of sensory testing in healthy controls.

    Sudden sensorineural hearing loss has been reported to be associated with diabetes mellitus, hypertension, and hyperlipidemia in previous studies. The aim of this study was to examine whether metabolic syndrome increases the risk of sudden sensorineural hearing loss in Taiwan. A case-control study. Tertiary university hospital. We retrospectively investigated 181 cases of sudden sensorineural hearing loss and 181 controls from the Department of Otorhinolaryngology, Kaohsiung Medical University Hospital, in southern Taiwan from 2010 to 2012, comparing their clinical variables. We analyzed the relationship between metabolic syndrome and sudden sensorineural hearing loss. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III with Asian modifications. The demographic and clinical characteristics, audiometry results, and outcome were reviewed. Subjects with metabolic syndrome had a 3.54-fold increased risk (95% confidence interval [CI] = 2.00-6.43, P diabetes mellitus, hypertension, and hyperlipidemia. With increases in the number of metabolic syndrome components, the risk of sudden sensorineural hearing loss increased (P for trend Vertigo was associated with a poor outcome (P = .02; 95% CI = 1.13~5.13, adjusted odds ratio = 2.39).

    To evaluate the risk of self-reported temporomandibular disorder (TMD) pain among adolescents in relation to previous head and/or neck injury. 3,101 enrollees (11 to 17 years of age) of a nonprofit integrated health-care system were interviewed by telephone. Two hundred four cases with self-reported TMD pain and 194 controls without self-reported TMD pain frequency-matched to the cases by age and gender completed standardized in-person interviews and physical examinations in which reports of previous head/neck injuries were recorded. Odds ratio (OR) estimates and 95% confidence intervals (CIs) of the relative risks of TMD pain associated with prior head and/or neck injuries were calculated using logistic regression. A greater proportion of subjects reporting TMD pain (36%) than controls (25%) had a history of head and/or neck injuries (OR = 1.8, 95% CI, 1.1-2.8). In a separate analysis, the presence of TMD based upon the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was assessed in relation to prior head and/or neck injury. Cases reporting TMD pain and meeting the RDC/TMD criteria for myofascial pain and/or arthralgia or arthritis were 2.0 (CI, 1.0-3.8) times more likely to have had a prior head injury than were controls with neither self-reported nor RDC/TMD pain diagnoses. The results suggest a modest association of prior head injuries with both self-reported and clinically diagnosed TMD pain in adolescents.

    Several studies in recent decades have examined the relationship between proprioceptive deficits and neck pain. However, there is no uniform conclusion on the relationship between the two. Clinically, proprioception is evaluated using the Joint Position Sense Error (JPSE), which reflects a person's ability to accurately return his head to a predefined target after a cervical movement. We focused to differentiate between JPSE in people with neck pain compared to healthy controls. Systematic review according to the PRISMA guidelines. Our data sources were Embase, Medline OvidSP, Web of Science, Cochrane Central, CINAHL and Pubmed Publisher. To be included, studies had to compare JPSE of the neck (O) in people with neck pain (P) with JPSE of the neck in healthy controls (C). Fourteen studies were included. Four studies reported that participants with traumatic neck pain had a significantly higher JPSE than healthy controls. Of the eight studies involving people with non-traumatic neck pain, four reported significant differences between the groups. The JPSE did not vary between neck-pain groups. Current literature shows the JPSE to be a relevant measure when it is used correctly. All studies which calculated the JPSE over at least six trials showed a significantly increased JPSE in the neck pain group. This strongly suggests that 'number of repetitions' is a major element in correctly performing the JPSE test. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Unintentional falls from windows are an important cause of paediatric morbidity. There have been no controlled studies to identify modifiable environmental risk factors for window falls in young children. The authors have piloted a case-control study to test procedures for case identification, subject enrolment, and environmental data collection. Case windows were identified when a child 0-9 years old presented for care after a fall from that window. Control windows were identified (1) from the child's home and (2) from the home of an age- and gender-matched child seeking care for an injury diagnosis not related to a window fall. Study staff visited enrolled homes to collect window measurements and conduct window screen performance tests. The authors enrolled and collected data on 18 case windows, 18 in-home controls, and 14 matched community controls. Six potential community controls were contacted for every one enrolled. Families who completed the home visit viewed study procedures positively. Case windows were more likely than community controls to be horizontal sliders (100% vs 50%), to have deeper sills (6.28 vs 4.31 inches), to be higher above the exterior surface (183 vs 82 inches), and to have screens that failed below a threshold derived from the static pressure of a 3-year-old leaning against the mesh (60.0% vs 16.7%). Case windows varied very little from in-home controls. Case-control methodology can be used to study risk factors for paediatric falls from windows. Recruitment of community controls is challenging but essential, because in-home controls tend to be over-matched on important variables. A home visit allows direct measurement of window type, height, sill depth, and screen performance. These variables should all be investigated in subsequent, larger studies covering major housing markets.

    Objective: To investigate the value of planned neck dissection combined with induction chemotherapy and concurrent chemoradiotherapy in regional control and the outcome of locally advanced head and neck squamous cell carcinoma. Methods: A prospective randomized controlled study totally enrolled sixty-four patients of head and neck squamous cell carcinomas(include oropharynx, hypopharynx, and larynx) in stages Ⅳa-Ⅳb with lymph node metastase was were N2-N3. All patients firstly received 2-3 cycles of induction chemotherapy(ICT), then divided into two groups randomly, according to the efficacy of ICT. Group A(the study group) received planned neck dissection(PND) and concurrent chemoradiotherapy(CCRT). Group B(the control group) received concurrent chemoradiotherapy(CCRT). The differences in clinicopathologic features, local recurrence(LR), regional recurrence(RR), disease-free survival(DFS), and overall survival(OS) between the two groups were estimated. SPSS 19.0 software was used to analyze the data. Results: Group A enrolled twenty-one patients, and group B enrolled forty-three patients.The follow-up of all patients were 4-55 months, median follow-up time was 22 months. In study group, two-year OS and DFS were 80.9% and 68.3%, respectively. In control group, two-year OS and DFS were 90.7% and 67.1%, respectively. There was no significant difference in gender( P =0.215), age( P =0.828), primary tumor site( P =0.927), LR( P =0.126), DFS( P =0.710), and OS( P =0.402) between the two groups, while the RR(χ(2)=5.640, P squamous cell carcinoma.

    Carotid paragangliomas are usually slowly enlarging and painless lateral neck masses. These mostly benign lesions are recognized due to their typical location, vessel displacement and specific blood supply, features that are usually seen on different imaging modalities. Surgery for carotid paraganglioma can be associated with immediate cerebrovascular complications or delayed neurological impairment.We are reporting the case of a 36-year-old man who presented with a painless mass on the right side of his neck 11 months after being treated for testicular cancer. After a fine-needle aspiration biopsy, he was diagnosed with a testicular cancer lymph node metastasis. Neck US and fluorine [F-18]-fluorodeoxy-D-glucose (FDG) PET-CT showed no signs of hypervascularity or vessel displacement. The patient underwent a level II to V functional neck dissection. During the procedure, suspicion of a carotid paraganglioma was raised and the tumour was carefully dissected from the walls of the carotid arteries with minimal blood loss and no cranial nerve dysfunction.The histology report revealed carotid paraganglioma with no metastasis in the rest of the lymph nodes. The patient's history of testicular germ cell tumour led to a functional neck dissection during which a previously unrecognized carotid paraganglioma was removed.Surgery for carotid PG can be associated with complications that have major impact on quality of life. A thorough assessment of the patient and neck mass must therefore be performed preoperatively in order to perform the surgical procedure under optimal conditions.

  19. Prevention of avascular necrosis in displaced talar neck fractures by hyperbaric oxygenation therapy: A dual case report

    Full Text Available Talar neck fractures are a rare injury that account for less then 2% of all foot fractures. Displaced fractures are associated with an exceedingly high rate of avascular necrosis (AVN. The incidence of AVN following Hawkins Type 3 fractures of the talar neck may approach 100%, particularly if diagnosis and reduction are delayed. Severe cases may present as pain and disability of the ankle and the subtalar joints due to a talar dome collapse, resulting in degenerative changes that usually require hind foot arthrodesis. We present two cases of traumatic displaced talar neck fractures which were treated surgically more than 2 weeks following injury due to a delay in diagnosis. Both patients underwent hyperbaric oxygen therapy (HBOT after the operation and neither resulted in AVN of the talus in a three-year follow-up. We suggest that this favorable result may be due to the beneficial effects of HBOT.

    Different periodontitis case definitions have been used in clinical research and epidemiology. The aim of this study was to determine more accurate criterion for the definition of mild and moderate periodontitis case to be applied to head and neck cancer individuals before radiotherapy. The frequency of periodontitis in a sample of 84 individuals was determined according to different diagnostic criteria: (1) Lopez et al. (2002);(2) Hujoel et al. (2006); (3) Beck et al. (1990); (4) Machtei et al. (1992); (5) Tonetti and Claffey (2005); (6) and Page and Eke (2007). All diagnosis were based on the clinical parameters obtained by a single calibrated examiner (Kw = 0.71). The individuals were evaluated before radiotherapy. They received oral hygiene instructions, and the cases diagnosed with periodontitis (Page and Eke 2007) were treated. The gold standard was the definition 6, and the others were compared by means of agreement, sensitivity (SS), specificity (SP), and the area under ROC curve. The kappa test evaluated the agreement between definitions. The frequency of periodontitis at baseline was 53.6 % (definition 1), 81.0 % (definition 2), 40.5 % (definition 3), 26.2 % (definition 4), 13.1 % (definition 5), and 70.2 % (definition 6). The kappa test showed a moderate agreement between definitions 6 and 2 (59.0 %) and definitions 6 and 1 (56.0 %). The criterion with higher SS (0.92) and SP (0.73) was definition 1. Definition 1 was the most accurate criterion to case periodontitis definition to be applied to head and neck cancer individuals.

    Objective: To evaluate the role of PET/CT in the approach to patients with head and neck cancer. Materials and Methods: Retrospective study of medical records and PET/CT images of 63 patients with head and neck cancer. Results: Alterations were observed in 76% of the cases. Out of these cases, 7 (11%) were considered as false-positive, with SUV < 5.0. PET/CT demonstrated negative results in 15 cases (24%). Among the 14 cases where the method was utilized for staging, 3 (22%) had their stages changed. Conclusion: PET/CT has shown to be of potential value in the routine evaluation of patients with head and neck cancer, but further studies of a higher number of cases are required to define a protocol for utilization of the method.

    Full Text Available Abstract Background Glomangiomyoma is a rare histological variant of glomus tumour. Clinically, it mimicks as a haemangioma and is challenging to diagnose. Its occurrence in the neck of a child has not been previously described. Case presentation A 3 year old girl presented with the complaints of painless progressive neck swelling in the right side for one and half year. Sonography, computed tomography (CT, magnetic resonance imaging (MRI, CT neck angiography and fine needle aspiration cytology (FNAC were suggestive of vacular malformation i.e. giant haemangioma or arteriovenous malformation. The mass was removed in toto under general anaesthesia without postoperative complications. The histopathology confirmed it to be glomangiomyoma with haemangiopericytoma like features. Conclusion It’s an extremely rare variant of glomus tumour and may be the first report of a glomangiomyoma in the neck of a child. Despite a rare entity, it should be borne in mind during differential diagnosis.

    Acute leukemia is the most common malignancy in children. We showed that low bone mass is prevalent among children with leukemia, especially in femur. Serum calcium, exercise, chemotherapy protocol, and radiotherapy are the main contributing factors. We suggest that early diagnosis and treatment of this problem could improve bone health in them. Acute leukemia is the most common malignancy in children and has been reported to be associated with low bone mass. Due to lack of sufficient data about the bone mineral density of children with leukemia in the Middle East, and inconsistencies between possible associated factors contributing to decreasing bone density in these children, we aimed to conduct a case-control study in Iran. This case-control study was conducted on 60 children with acute leukemia and 60 age- and sex-matched healthy controls. Anthropometric data, sun exposure, puberty, physical activity, and mineral biochemical parameters were assessed. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DEXA). Data analysis was done by SPSS software v. 21. Serum calcium was higher in the control group (P = 0.012) while serum phosphorous, alkaline phosphatase, and serum 25(OH)D 3 were higher in children with leukemia with P values of 0.04, 0.002, and 0.036, respectively. Sun exposure and physical activity were more in healthy controls (P values children with leukemia, especially in the femoral neck. Serum calcium, physical activity, chemotherapy protocol, and radiotherapy are the main contributing factors.

    We present two cases of fetal neck masses that were initially diagnosed by ultrasound and further evaluated with prenatal MRI. MRI findings aided in further delineating the neck masses, increasing confidence in the final diagnosis (cervical teratoma and cystic hygroma). With the fetal airway typically filled with fluid that is of high signal on T2-weighted sequences, MRI images in three planes could identify whether the fetal larynx and trachea were partially or completely compressed by the neck tumor. This information was particularly useful in determining if a controlled delivery such as ex utero intrapartum treatment (EXIT) was necessary and aided the surgeons in planning their approach to establishing airway control in the delivery room.

    Elevated concentrations of homocyst(e)ine are thought to increase the risk of vascular diseases including coronary heart disease and cerebrovascular disease. We searched MEDLINE (1966-1999), EMBASE (1974-1999), SciSearch (1974- 1999), and Dissertation Abstracts (1999) for articles and theses about homocyst(e)ine concentration and coronary heart disease and cerebrovascular disease. We included 57 publications (3 cohort studies, 12 nested case-control studies, 42 case-control studies) that reported results on 5518 people with coronary heart disease (11,068 control subjects) and 1817 people with cerebrovascular disease (4787 control subjects) in our analysis. For coronary heart disease, the summary odds ratios (OR) for a 5-micromol/l increase in homocyst(e)ine concentration were 1.06 (95% CI : 0.99-1.13) for 2 publications of cohort studies, 1.23 (95% CI : 1.07-1.41) for 10 publications of nested case-control studies, and 1.70 (95% CI : 1.50-1.93) for 26 publications of case-control studies. For cerebrovascular disease, the summary OR for a 5-micromol/l increase in homocyst(e)ine concentration were 1.10 (95% CI : 0.94-1.28) for 2 publications of cohort studies, 1.58 (95% CI : 1.35-1.85) for 5 publications of nested case-control studies, and 2.16 (95% CI : 1.65-2.82) for 17 publications of case-control studies. Prospective studies offer weaker support than case-control studies for an association between homocyst(e)ine concentration and cardiovascular disease. Although other lines of evidence support a role for homocyst(e)ine in the pathogenesis of cardiovascular disease, more information from prospective epidemiological studies or clinical trials is needed to clarify this role.

    Late complications of head and neck cancer survivors include neck muscle atrophy and soft-tissue fibrosis. We present an autopsy case of neck muscle atrophy and soft-tissue fibrosis (sternocleidomastoid, omohyoid, digastric, sternohyoid, sternothyroid, and platysma muscles) within the radiation field after modified radical neck dissection type I and postoperative radiotherapy for floor of mouth cancer. A 70-year-old man underwent primary tumor resection of the left floor of mouth, left marginal mandibulectomy, left modified radical neck dissection type I, and reconstruction with a radial forearm free flap. The patient received adjuvant radiotherapy. The dose to the primary tumor bed and involved neck nodes was 63 Gy in 35 fractions over 7 weeks. Areas of subclinical disease (left lower neck) received 50 Gy in 25 fractions over 5 weeks. Adjuvant chemotherapy was not administered.

    Multiple system atrophy is a neurodegenerative disease that affects autonomic and motor systems. Patients with multiple system atrophy usually experience lower urinary tract symptoms, which sometimes appear as an initial symptom before the emergence of the generalized symptoms. An open bladder neck during the filling phase on video urodynamic study is one characteristic imaging finding after the diagnosis of multiple system atrophy, but has not previously been reported at an early phase of the disease. We report a case in which an open bladder neck was observed on several imaging modalities before generalized symptoms emerged. Because occult neurogenic bladder might exist in patients whose lower urinary tract symptoms are resistant to pharmacotherapy, we report this case to raise awareness of the importance of sufficient imaging evaluations. An open bladder neck might be an important imaging finding for diagnosing multiple system atrophy, irrespective of the presence of generalized symptoms. This finding could help avoid false diagnosis and unnecessary treatment. © 2017 The Japanese Urological Association.

    Full Text Available Abstract Introduction We present an interesting and unusual case of a 61-year-old woman with bilateral, undisplaced, stress neck of femur fractures associated with short-term steroid use. Insufficiency fractures of the neck of femur without preceding trauma have been described in the literature, although bilateral involvement is infrequent. These fractures have been associated with strenuous exercise, seizures, renal osteodystrophy, fluoride treatment, long-term corticosteroid use, amenorrhoea, abnormal anatomy and osteomalacia due to nutritional and/or hormonal factors. Case Presentation The case we present differs from other published reports, in that the patient's symptoms developed acutely after only a short course of steroids and with no associated trauma or strenuous exercise. It is also the only case described where no operative intervention was required. Conclusion Our case reiterates the importance of considering insufficiency or stress fractures in high-risk patients who present with musculoskeletal pain. Institution of bone protection should also be considered in these patients. Morbidity related to delayed treatment has been well documented, so a high level of clinical suspicion is imperative.

    The 5th metacarpal fractures accounts for 38% of all hand fractures given that the neck is the weakest point in metacarpals, so neck fracture is the most common metacarpal fracture. Surgical fixation is also advocated for such fractures to prevent mal-rotation of the little finger which will lead to fingers overlap in a clenched fist. Various methods are available for fixation of such fractures, like intramedullary & transverse pinning. There are very few reports in the literature comparing both techniques. Authors wanted to compare outcomes and complications of transverse pinning versus intramedullary pinning in fifth metacarpal's neck fractures. A single-center, parallel group, prospective, randomized study was conducted at an academic Level 1 Trauma Center from October 2014 to December 2016. A total of 80 patients with 5th metacarpal's neck fractures were randomized to pinning using either transverse pinning (group A) or intramedullary pinning (group B). Patients were assessed clinically on range of motion, patient-reported outcome using the Quick-DASH (Disabilities of the Arm, Shoulder, and Hand) questionnaire & radiographically. Two blinded observers assessed outcomes. At final follow up for each patient (12 months) the statistically significant differences were observed in operative time, the transverse pinning group showed shorter operative time, as well as complication rate as complications were observed only in intramedullary pinning group. No differences were found in range of motion or the Quick -DASH score. Both techniques are equally safe and effective treatment option for 5th metacarpal's neck fractures. The only difference was shorter operative time & less incidence of complications in transverse pinning group. Level II, Therapeutic study.

    Purpose: To identify the risk factors for moderate to severe subcutaneous fibrosis after whole neck irradiation. Methods and Materials: We analyzed 233 cases of patients who had undergone whole neck irradiation with 4-MV X-ray or 8-10-MeV electrons, or both, and had been followed with regard to their skin condition for at least 1 year. The prescribed dose to the whole neck ranged from 19.2 to 72.4 Gy (median 50). The skin-absorbed dose was specified as that at a depth of 4.1 mm (d4.1-mm depth ), and a biologically equivalent dose (BED) of d4.1-mm depth was also estimated (BED 1.8 4.1-mm depth ). Results: Univariate analysis revealed that previous neck dissection, concurrent chemotherapy, corticosteroid administration as a part of chemotherapy, fractionation, and BED 1.8 4.1-mm depth were significant prognostic variables. Multivariate analysis showed that BED 1.8 4.1-mm depth and previous neck dissection were the only prognostic variables for moderate to severe subcutaneous fibrosis. Conclusion: A high dose to a 4.1-mm depth of the skin and a history of neck dissection were identified as the predominant risk factors for moderate to severe subcutaneous fibrosis after whole neck irradiation. A subcutaneous dose should be considered in radiotherapy treatment planning involving the whole neck, especially in cases in which patients have undergone previous neck dissection

  13. Primary Hydatid Cyst of the Neck

    Hydatid cysts in the neck are relatively exceptional, even in areas where Echinococcus granulosis is endemic, such as Asia. Although liver and lung are frequent sites of involvement, it can involve all tissues, with neck remaining one of the most rare sites. It should come in the differential diagnosis of cystic lesion of neck, as the treatment options differ widely from common neck cysts. The role of radiological investigation is important and, in these cases, the involvement of other organs should be investigated. Serological tests may be helpful. The major treatment modality is surgical and the cyst should be excised as a whole, without being ruptured, to prevent any treatment complications, as the cyst fluid can initiate an anaphylactic reaction. Postoperative albendazole therapy is recommended particularly when there is intra-operative spillover. We report a case of an isolated hydatid cyst localized in the anterior triangle of the neck without any pulmonary or hepatic involvement. (author)

  14. Dizzy people perform no worse at a motor imagery task requiring whole body mental rotation; a case-control comparison

    2013-06-01

    Full Text Available We wanted to find out whether people who suffer from dizziness take longer than people who do not, to perform a motor imagery task that involves implicit whole body rotation. Our prediction was that people in the ‘dizzy’ group would take longer at a left/right neck rotation judgment task but not a left/right hand judgment task, because actually performing the former, but not the latter, would exacerbate their dizziness. Secondly, we predicted that when dizzy participants responded to neck rotation images, responses would be greatest when images were in the upside-down orientation; an orientation with greatest dizzy-provoking potential. To test this idea, we used a case-control comparison design. One hundred and eighteen participants who suffered from dizziness and 118 age, gender, arm pain and neck pain matched controls took part in the study. Participants undertook two motor imagery tasks; a left/right neck rotation judgment task and a left/right hand judgment task. The tasks were completed using the Recognise program; an on-line reaction time task program. Images of neck rotation were shown in four different orientations; 0°, 90°, 180° and 270°. Participants were asked to respond to each ‘neck’ image identifying it as either ‘right neck rotation’ or a ‘left neck rotation’, or for hands, a right or a left hand. Results showed that participants in the ‘dizzy’ group were slower than controls at both tasks (p= 0.015, but this was not related to task (p= 0.498. Similarly, ‘dizzy’ participants were not proportionally worse at images of different orientations (p= 0.878. Our findings suggest impaired performance in dizzy people, an impairment that may be confined to motor imagery or may extend more generally.

    Full Text Available Background : One of the most common treatments of displaced fracture of femoral neck in elderly is bipolar hemiarthroplasty. Method : Two hundred and seventy patients of displaced fracture of femoral neck were treated by bipolar hemiarthroplasty. The Mean age of the patients at the time of surgery was 69.80 years. Results : Follow up ranged between 12 months and 120 months. There were 8 cases each of acetabular erosion and protrusion with 10 cases of femoral stem loosening. Eight cases had post operative dislocation requiring open reduction. Eighteen patients got revision surgery to total hip replacement. The overall incidence of DVT/PE was 9.9% which declined after regular use of low molecular weight heparin. Eleven patients had post operative infection. There were 54.2 % excellent results, 21.0 % good results, 10.7 % fair and 3.7% poor results. Conclusion : Elderly patients with displaced fracture of neck femur are able to ambulate early after Cemented bipolar hemi arthroplasty. The complication rate is low, the component survival long and pre injury functional status is restored in majority of patients.

    Wet cupping therapy (WCT) is a traditional complementary method recommended to decrease the symptoms of a lot of diseases and used in the treatment of pain syndromes. In this pilot study, the possible effects of wet cupping therapy on nonspecific neck and upper shoulder pain were investigated. Sixty one eligible volunteer participants with nonspecific neck and upper shoulder pain for at least 3 months were allocated. The Numeric Rating Scale (NRS) was used to assess pain scores. Pain scores were recorded before and after wet cupping therapy. The mean scores of neck pain in study group were 7.02 (SD = 1.8) before and 3.70 (SD = 2.2) after cupping therapy. The decrease of pain scores between pre- and post-test was statistically significant (p < 0.05). It can be stated that WCT has potential therapeutic effect in nonspecific neck and upper shoulder pain. Future full-scale randomized controlled trials will be needed to provide firm evidence of the effectiveness of this intervention. Copyright © 2016 Elsevier Ltd. All rights reserved.

  17. Chronic neck pain and masticatory dysfunction.

    Catanzariti, Jean-François; Debuse, Thierry; Duquesnoy, Bernard

    2005-12-01

    Chronic nonspecific neck pain is a common problem in rheumatology and may resist conventional treatment. Pathophysiological links exist between the cervical spine and masticatory system. Occlusal disorders may cause neck pain and may respond to dental treatment. The estimated prevalence of occlusal disorders is about 45%, with half the cases being due to functional factors. Minor repeated masticatory dysfunction (MD) with craniocervical asymmetry is the most common clinical picture. The pain is usually located in the suboccipital region and refractory to conventional treatment. The time pattern may be suggestive, with nocturnal arousals or triggering by temporomandibular movements. MD should be strongly suspected in patients with at least two of the following: history of treated or untreated MD, unilateral temporomandibular joint pain and clicking, lateral deviation during mouth opening, and limitation of mouth opening (less than three fingerbreadths). Rheumatologists should consider MD among causes of neck pain, most notably in patients with abnormal craniocervical posture, signs linking the neck pain to mastication, and clinical manifestations of MD. Evidence suggesting that MD may cause neck pain has been published. However, studies are needed to determine whether treatment of MD can relieve neck pain.

    Thyroid cancer incidence and diagnostic radiography exposures, particularly computed tomography (CT) scanning and nuclear medicine examinations, have increased substantially in the USA. However, very few epidemiologic studies have directly investigated their associations. A population-based case-control study was conducted in Connecticut in 2010-2011, including 462 histologically confirmed incident thyroid cancer cases and 498 population-based controls. Multivariate unconditional logistic regression models were used to estimate the associations between diagnostic radiography and the risk of thyroid cancer, controlling for potential confounding factors. Exposure to any form of diagnostic radiography was associated with an increased risk of well-differentiated thyroid microcarcinoma [tumor size≤10 mm, odds ratio (OR)=2.76, 95% confidence interval (CI): 1.31-5.81]. The highest risk increase occurred with nuclear medicine examinations (excluding cardiology tests and thyroid uptake studies; OR=5.47, 95% CI: 2.10-14.23), followed by chest CT scanning (OR=4.30, 95% CI: 1.66-11.14), head and neck CT scanning (OR=3.88, 95% CI: 1.75-8.63), upper gastrointestinal series (OR=3.56, 95% CI: 1.54-8.21), lower gastrointestinal series (OR=3.29, 95% CI: 1.41-7.66), kidney radiography involving dye injection into a vein or artery (OR=3.21, 95% CI: 1.20-8.54), mammography (OR=2.95, 95% CI: 1.14-7.61), chest radiography (OR=2.93, 95% CI: 1.37-6.29), and abdomen CT scanning (OR=2.54, 95% CI: 1.02-6.30). No significant associations were found between these imaging modalities and thyroid tumors larger than 10 mm. This study provides the first direct evidence that CT scanning and nuclear medicine examinations are associated with an increased risk of thyroid cancer. The novel finding that an array of diagnostic radiography procedures are associated with thyroid microcarcinomas warrants further investigation.

    This epidemiology study examined risk factors uniquely associated with spasmodic dysphonia (SD). Case-control. A questionnaire was administered to 150 patients with SD (with and without coexisting vocal tremor) and 136 patients with other structural, neurological, and functional voice disorders (excluding SD and vocal tremor). Questions included personal and family medical histories, environmental exposures, trauma, illnesses, voice use habits, and the Short Form 36. Several factors were uniquely associated with SD (α = .05), including: 1) a personal history of cervical dystonia, sinus and throat illnesses, mumps, rubella, dust exposure, and frequent volunteer voice use, 2) a family history of voice disorders, 3) an immediate family history of vocal tremor and meningitis, and 4) an extended family history of head and neck tremor, ocular disease, and meningitis. Vocal tremor coexisted with SD in 29% of cases. Measles and mumps vaccines were protective for SD. SD is likely multifactorial and associated with several endogenous and exogenous factors. Certain viral exposures, voice use patterns, and familial neurological conditions may contribute to the onset of SD later in life.

Matching of cases and controls is frequently employed to control the effects of known potential confounding variables. The analysis of matched data requires specific statistical methods.Methods: The objective of this study was to determine the proportion of published, peer reviewed matched case-control studies that used statistical methods appropriate for matched data. Using a comprehensive set of search criteria we identified 37 matched case-control studies for detailed analysis.Results: Among these 37 articles, only 16 studies were analyzed with proper statistical techniques (43%. Studies that were properly analyzed were more likely to have included case patients with cancer and cardiovascular disease compared to those that did not use proper statistics (10/16 or 63%, versus 5/21 or 24%, P = 0.02. They were also more likely to have matched multiple controls for each case (14/16 or 88%, versus 13/21 or 62%, P = 0.08. In addition, studies with properly analyzed data were more likely to have been published in a journal with an impact factor listed in the top 100 according to the Journal Citation Reports index (12/16 or 69%, versus 1/21 or 5%, P ≤ 0.0001.Conclusion: The findings of this study raise concern that the majority of matched case-control studies report results that are derived from improper statistical analyses. This may lead to errors in estimating the relationship between a disease and exposure, as well as the incorrect adaptation of emerging medical literature.Keywords: case-control, matched, dependent data, statistics

    The aim of this study was to investigate whether there is an association between text neck and neck pain in young adults. Observational cross-sectional study with 150 18-21-year-old young adults from a public high school in the state of Rio de Janeiro was performed. In the self-report questionnaire, the participants answered questions on sociodemographic factors, anthropometric factors, time spent texting or playing on a mobile phone, visual impairments, and concern with the body posture. The neck posture was assessed by participants' self-perception and physiotherapists' judgment during a mobile phone texting message task. The Young Spine Questionnaire was used to evaluate the neck pain. Four multivariate logistic regression models were fitted to investigate the association between neck posture during mobile phone texting and neck pain, considering potential confounding factors. There is no association between neck posture, assessed by self-perception, and neck pain (OR = 1.66, p = 0.29), nor between neck posture, assessed by physiotherapists' judgment, and neck pain (OR = 1.23, p = 0.61). There was also no association between neck posture, assessed by self-perception, and frequency of neck pain (OR = 2.19, p = 0.09), nor between neck posture, assessed by physiotherapists' judgment, and frequency of neck pain (OR = 1.17, p = 0.68). This study did not show an association between text neck and neck pain in 18-21-year-old young adults. The findings challenge the belief that neck posture during mobile phone texting is associated to the growing prevalence of neck pain.

    A 71-year-old man visited our hospital for examination of a soft neck mass. Computed tomography and magnetic resonance imaging scans showed a well-circumscribed large lipomatous tumor with multiple nodules inside. Atypical lipomatous tumor or lipoma involving the lymph nodes was considered. Pathological examination of the surgical specimen suggested typical lipoma including multiple metastatic foci from gastric cancer. Subsequent endoscopy revealed a gastric tumor, which was histologically proven to be signet-ring cell carcinoma. Considering these findings, this case was diagnosed as tumor-to-tumor metastasis to lipoma. We present the first such case with imaging and clinical characteristics. (orig.)

    Although the value of surgeon-performed neck ultrasound (SPUS) for thyroid nodules has been validated, the utility of intraoperative ultrasound (US) in modified radical neck dissection (MRND) has not been reported in the literature. The aim of this study was to analyze the utility of intraoperative SPUS in assessing the completeness of MRND for thyroid cancer. Between 2007 and 2011, a total of 25 patients underwent MRND by 1 surgeon for thyroid cancer. All patients underwent intraoperative SPUS, which was repeated at the end of the neck dissection (completion US) to look for missed lymph nodes (LNs). There were 10 male and 15 female patients. Pathology included 23 papillary and 2 medullary carcinomas. The number of LNs removed per case was 23 ± 2, and the number of positive was LNs 5 ± 1. In 4 (16%) cases, intraoperative US detected 7 residual LNs, which would have been missed, if completion US were not done. These missed LNs were located in low-level IV (3 nodes), high-level II (2 nodes), and posterior level V (2 nodes) and measured 1.4 ± 0.2 cm. At follow-up, recurrence was seen in 2 (8%) patients, including a superior mediastinal recurrence in a patient with tall cell cancer and a jugular LN recurrence at level II in another patient with papillary thyroid cancer. This pilot study shows that intraoperative SPUS can help assess the completeness of MRND. According to our results, intraoperative completion US identifies LNs missed by palpation 16% of the time.

As previous studies regarding the association between CDH1 promoter methylation and head and neck squamous cell carcinoma (HNSCC have yielded inconsistent conclusions, a meta-analysis was performed. A systematic literature review was undertaken from four databases: PubMed, Embase, Google Scholar, and Web of Science. Finally, a total of 23 studies (including 1,727 cases of HNSCC and 555 normal controls were included in the present study. Our results showed that the frequency of CDH1 promoter methylation in HNSCC was statistically greater than in controls (odds ratio [OR] =5.94, 95% confidence interval [CI]: 3.36–10.51, P<0.001. In reported cases of HNSCC, CDH1 promoter methylation was statistically associated with tumor stage (OR =0.46, 95% CI: 0.27–0.78, P=0.004 and a history of alcohol consumption (OR =6.04, 95% CI: 2.41–15.14, P<0.001.

    Correct control selection is crucial to the internal validity of case-control studies. Little information exists on differences between population and hospital controls in case-control studies on cancers in Chinese hospital setting. We conducted three parallel case-control studies on leukemia, breast and colorectal cancers in China between 2009 and 2010, using population and hospital controls to separately match 540 incident cases by age, gender and residency at a 1:1 ratio. Demographic and lifestyle factors were measured using a validated questionnaire in face-to-face interview. Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained using conditional logistic regression analyses. The two control groups had closely similar exposure distributions of 15 out of 16 factors, with the only exception being that hospital controls were less likely to have a BMI ≥ 25 (OR = 0.71, 95% CI: 0.54, 0.93). For exposure of green tea drinking, the adjusted ORs (95% CIs) comparing green tealeaves intake ≥ 1000 grams annually with non-drinkers were 0.51 (0.31, 0.83) and 0.21 (0.27, 0.74) for three cancers combined, 0.06 (0.01, 0.61) and 0.07 (0.01, 0.47) for breast cancer, 0.52 (0.29, 0.94) and 0.45 (0.25, 0.82) for colorectal cancer, 0.65 (0.08, 5.63) and 0.57 (0.07, 4.79) for leukemia using hospital and population controls respectively. The study found that hospital controls were comparable with population controls for most demographic characteristics and lifestyle factors measured, but there was a slight difference between the two control groups. Hospital outpatients provide a satisfactory control group in hospital-based case-control study in the Chinese hospital setting.

    Objective We aim to describe a novel, label-free, real-time imaging technique, coherent Raman scattering (CRS) microscopy, for histopathological evaluation of head and neck cancer. We evaluated the ability of CRS microscopy to delineate between tumor and nonneoplastic tissue in tissue samples from patients with head and neck cancer. Study Design Prospective case series. Setting Tertiary care medical center. Subjects and Methods Patients eligible were surgical candidates with biopsy-proven, previously untreated head and neck carcinoma and were consented preoperatively for participation in this study. Tissue was collected from 50 patients, and after confirmation of tumor and normal specimens by hematoxylin and eosin (H&E), there were 42 tumor samples and 42 normal adjacent controls. Results There were 42 confirmed carcinoma specimens on H&E, and CRS microscopy identified 37 as carcinoma. Of the 42 normal specimens, CRS microscopy identified 40 as normal. This resulted in a sensitivity of 88.1% and specificity of 95.2% in distinguishing between neoplastic and nonneoplastic images. Conclusion CRS microscopy is a unique label-free imaging technique that can provide rapid, high-resolution images and can accurately determine the presence of head and neck carcinoma. This holds potential for implementation into standard practice, allowing frozen margin evaluation even at institutions without a histopathology laboratory.

    Full Text Available Background : The spectrum of head and neck tumors in children continues to be the cause of diverse, diagnostically challenging issues. Aims : To demonstrate and compare the unique clinicopathological features in our study population and their correlations with the final histopathological diagnosis. Methods : Fifty-three children with head and neck cancer were examined thoroughly at the Otorhinolaryngology department in a tertiary care teaching hospital followed by histopathological studies. Results : Lymphomas were the most common malignant lesions seen followed by rhabdomyosarcomas, nasopharyngeal carcinomas, and others like thyroid carcinomas and eosinophilic granulomas. In the neck, the commonest cause of primary malignant disease was lymphoma; however, the most frequent lesion was reactive lymphadenitis. In the sinonasal region, the commonest malignancy was rhabdomyosarcoma, which often had extension to the orbit and the face. Recurrent epistaxis was found universally in the malignant cases of this region. In the facial region, disfiguring swelling with proptosis was mainly caused by rhabdomyosarcoma. The only case of tonsillar malignancy was due to non-Hodgkin lymphoma. The duration of disease was less than 1 year. Conclusion : The most common manifestation of the malignant lesions in the pediatric age group was with a history of an enlarging, painless neck swelling. Still, an insignificant lump in the neck or recurrent bleeding from nose may be the manifestation of an underlying cancer.

    2009-09-01

    Full Text Available Abstract Background In haplotype-based candidate gene studies a problem is that the genotype data are unphased, which results in haplotype ambiguity. The measure 1 quantifies haplotype predictability from genotype data. It is computed for each individual haplotype, and for a measure of global relative efficiency a minimum value is suggested. Alternatively, we developed methods directly based on the information content of haplotype frequency estimates to obtain global relative efficiency measures: and based on A- and D-optimality, respectively. All three methods are designed for single populations; they can be applied in cases only, controls only or the whole data. Therefore they are not necessarily optimal for haplotype testing in case-control studies. Results A new global relative efficiency measure was derived to maximize power of a simple test statistic that compares haplotype frequencies in cases and controls. Application to real data showed that our proposed method gave a clear and summarizing measure for the case-control study conducted. Additionally this measure might be used for selection of individuals, who have the highest potential for improving power by resolving phase ambiguity. Conclusion Instead of using relative efficiency measure for cases only, controls only or their combined data, we link uncertainty measure to case-control studies directly. Hence, our global efficiency measure might be useful to assess whether data are informative or have enough power for estimation of a specific haplotype risk.

    2012-11-01

    A 64-year-old man with acute onset neck pain was referred to physical therapy by a neurosurgeon. The purpose of this case study is to examine the process of differential diagnosis in a patient with neck pain and to discuss common diagnostic errors that can occur in the outpatient setting. The patient had an 8-week history of neck pain, which was worse when running and lifting objects. He presented with imaging of the cervical spine demonstrating degenerative changes. During the examination, several differential diagnoses were considered. A thorough physical examination of the cervical spine and upper quarter failed to reproduce his symptoms. At that time, the physical therapist was suspicious that the origin of the patient's neck pain was non-mechanical in nature. Additional testing during the examination included having the patient exercise briefly on gym equipment; this reproduced his symptoms. After additional positional and postural changes did not alleviate the symptoms, he stopped exercising, and his pain ceased. The patient was referred back to his primary care physician who ordered cardiovascular testing including an electrocardiogram and echocardiogram. These tests revealed significant cardiac abnormalities including multi-vessel blockage of the coronary arteries and evidence of infarction. He underwent a coronary artery bypass graft 4 days later. To make an appropriate differential diagnosis, physical therapists must use a patient-centered model of clinical reasoning and meta-cognition and have an awareness of diagnostic errors such that they can be avoided. The goal of the physical therapy examination, including differential diagnosis, is to efficiently classify the patient for treatment or to direct patients to the proper healthcare provider, thereby minimizing and preventing mortality and morbidity.

    2010-10-01

    To determine the impact of occupational psychological/social and mechanical factors on neck pain, a prospective cohort study with a follow-up period of 2 years was conducted with a sample of Norwegian employees. The following designs were tested: (i) cross-sectional analyses at baseline (n=4569) and follow-up (n=4122), (ii) prospective analyses with baseline predictors, (iii) prospective analyses with average exposure over time [(T1+T2)/2] as predictor, and (iv) prospective analyses with measures of change in exposure from T1 to T2 as predictors. A total of 2419 employees responded to both the baseline and follow-up questionnaire. Data were analyzed using ordinal logistic regression. After adjustment for age, sex, neck pain at T1, and other exposure factors that had been estimated to be confounders, the most consistent risk factors were role conflict (highest OR 2.97, 99% CI: 1.29-6.74) and working with arms raised to or above shoulder level (highest OR 1.37, 99% CI: 1.05-1.78). The most consistent protective factors were empowering leadership (lowest OR 0.53, 99% CI: 0.35-0.81) and decision control (lowest OR 0.60, 99% CI: 0.36-1.00). Hence, psychological and social factors are important precursors of neck pain, along with mechanical factors. Although traditional factors such as quantitative demands and decision control play a part in the etiology of neck pain at work, in this study several new factors emerged as more important.

    Navigation surgery, initially applied in rhinology, neurosurgery and orthopaedic cases, has been developed over the last twenty years. Surgery based on computed tomography data has become increasingly important in the head and neck region. The technique for hardware fusion between RMI and computed tomography is also becoming more useful. We use such device since 2006 in head and neck carcinologic situation. Navigation allows control of the resection in order to avoid and protect the precise anatomical structures (vessels and nerves). It also guides biopsy and radiofrequency. Therefore, quality of life is much more increased and morbidity is decreased for these patients who undergo major and mutilating head and neck surgery. Here we report the results of 33 navigation procedures performed for 31 patients in our institution.

    The aim of this study was to investigate whether isometric neck extension exercise restores physiological cervical lordosis and reduces pain. Sixty-five patients with loss of cervical lordosis were randomly assigned to exercise (27 women, 7 men; mean age, 32.82 ± 8.83 yrs) and control (26 women, 5 men; mean age, 33.48 ± 9.67 yrs) groups. Both groups received nonsteroidal anti-inflammatory drugs for 10 days. The exercise group received additional therapy as a home exercise program, which consisted of isometric neck extension for 3 mos. Neck pain severity and cervical lordosis were measured at baseline and at 3 mos after baseline. Compared with baseline levels, cervical lordosis angle was significantly improved in the exercise group (P cervical lordosis angle returned to physiological conditions (85.2% vs. 22.5%; P pain intensity was significantly reduced in both groups compared with baseline levels (for all, P pain was about twice in the exercise group compared with the control group (P cervical lordosis and pain.

    CT and MR imaging have become effective imaging modalities in the evaluation of primary head and neck neoplasms. As radiologists have gained experience in head and neck imaging, certain pitfalls have become evident. Identification of pathologic lymph nodes is the critical element in staging neoplasms of the head and neck. The diagnosis of cervical lymphadenopathy may be complicated by confusion with normal structures, inadequate contrast opacification of vascular structures, and poor scanning technique. This paper illustrates these potential problem areas on both CT and MR images and offers the authors' approach to further evaluation in problem cases

    To test whether supervised pelvic floor exercises antenatally will reduce the incidence of postpartum stress incontinence in at-risk primigravidae with bladder neck mobility, ultrasonically proven. Single blind, randomised controlled trial. Antenatal clinic in a UK NHS Trust Hospital. Two hundred and sixty-eight primigravidae attending an antenatal clinic at approximately 20 weeks of gestation with bladder neck mobility, on standardised valsalva, of 5 mm or more linear movement. The median age was 28, ranging from 16 to 47 years. Patients randomised to supervised pelvic floor exercises (n = 139) attended a physiotherapist at monthly intervals from 20 weeks until delivery. The exercises comprised three repetitions of eight contractions each held for six seconds, with two minutes rest between repetitions. These were repeated twice daily. At 34 weeks of gestation the number of contractions per repetition was increased to 12. Both the untreated control group and the study group received verbal advice on pelvic floor exercises from their midwives antenatally. Subjective reporting of stress incontinence at three months postpartum. Pelvic floor strength, using perineometry, and bladder neck mobility measured by perineal ultrasound. Of the 268 women enrolled, information on the main outcome variable was available for 110 in the control group and 120 in the study group. Fewer women in the supervised pelvic floor exercise group reported postpartum stress incontinence, 19.2% compared with 32.7% in the control group (RR 0.59 [0.37-0.92]). There was no change in bladder neck mobility and no difference in pelvic floor strength between groups after exercise, although all those developing postpartum stress incontinence had significantly poorer perineometry scores than those who were continent. The findings suggest that antenatal supervised pelvic floor exercises are effective in reducing the risk of postpartum stress incontinence in primigravidae with bladder neck mobility.

    Full Text Available Context. The possibility of cephalic venous hypertension with the resultant facial edema and elevated cerebrospinal fluid pressure continues to challenge head and neck surgeons who perform bilateral radical neck dissections during simultaneous or staged procedures. Case Report. The staged procedure in patients who require bilateral neck dissections allows collateral venous drainage to develop, mainly through the internal and external vertebral plexuses, thereby minimizing the risks of deleterious consequences. Nevertheless, this procedure has disadvantages, such as a delay in definitive therapy, the need for a second hospitalization and anesthesia, and the risk of cutting lymphatic vessels and spreading viable cancer cells. In this paper, we discuss the rationale and feasibility of preserving the external jugular vein. Considering the limited number of similar reports in the literature, two cases in which this procedure was accomplished are described. The relevant anatomy and technique are reviewed and the patients’ outcomes are discussed. Conclusion. Preservation of the EJV during bilateral neck dissections is technically feasible, fast, and safe, with clinically and radiologically demonstrated patency.

    Full Text Available Necrotizing infections of the head and neck are rare conditions in our hospital. Clinical and microbiological characteristics of three consecutive cases treated in Haukeland University Hospital in western Norway in the year 2010 are described. Two cases of Lemierre’s syndrome and one case with a descending necrotizing mediastinitis (DNM were diagnosed. All three cases were treated with broad spectrum antibiotics and in two cases surgery was possible. Hyperbaric oxygen treatment (HBOT with intensive care facilities became recently available at our hospital, and this treatment was used in all these patients regardless of surgery. In one case we describe the use of HBOT on the basis of strong clinical suspicion of anaerobic infection only. Bacterial identification by partial sequencing of the 16SrDNA gene proved to be a useful supplement to conventional culture techniques. All the cases all demonstrated a significant clinical improvement after introduction of HBOT. When HBOT is available, it should be considered as adjunctive treatment in extensive infections with anaerobes.

    Neck pain is a significant societal burden due to its high prevalence and healthcare costs. While physical activity can help to manage other forms of chronic musculoskeletal pain, little data exists on the relationship between physical activity and neck pain. The purpose of this study was to compare physical activity levels between individuals with neck pain and healthy controls, and then to relate disability, fear of movement, and pain sensitivity measures to physical activity levels in each...

    This study was to determine the prevalence and work-related risk factors of neck-upper extremity musculoskeletal disorders (MSDs) among video display terminal (VDT) users. A comparative cross-sectional study was conducted; there were 60 VDT users and 35 controls. The participants filled in a structured questionnaire, had electrophysiological tests and an X-ray of the neck. The prevalence of MSDs was higher (28.3%) among VDTs users compared to controls (14.3%) with no statistically significant difference. The prevalence of cervical disorders with or without radiculopathy (18.3%) was the most common disorder followed by carpal tunnel syndrome (6.6%). The mean (SD) age of MSD cases (51 ± 7.2 years) was statistically significantly higher than of the controls (42.8 ± 9). Physical exposure to prolonged static posture (OR: 6.9; 95% CI: 0.83-57.9), awkward posture (OR: 5.5; 95% CI: 0.6-46.4) and repetitive movements (OR: 5.5; 95% CI: 0.65-46.4) increased risk of MSDs with a statistically significant difference for static posture only (p < .05). VDT users experienced more job dissatisfaction, work-overload and limited social support from supervisors and colleagues. VDT use did not increase the risk of neck-upper extremity MSDs. The risk increased with older age and static posture.

    Current evidence suggests that neck pain is negatively associated with health-related quality of life (HRQoL). However, these studies are cross-sectional and do not inform the association between neck pain and future HRQoL. The purpose of this study was to investigate the association between increasing grades of neck pain severity and HRQoL 6 months later. In addition, this longitudinal study examines the crude association between the course of neck pain and HRQoL. This is a population-based cohort study. Eleven hundred randomly sampled Saskatchewan adults were included. Outcome measures were the mental component summary (MCS) and physical component summary (PCS) of the Short-Form-36 (SF-36) questionnaire. We formed a cohort of 1,100 randomly sampled Saskatchewan adults in September 1995. We used the Chronic Pain Questionnaire to measure neck pain and its related disability. The SF-36 questionnaire was used to measure physical and mental HRQoL 6 months later. Multivariable linear regression was used to measure the association between graded neck pain and HRQoL while controlling for confounding. Analysis of variance and t tests were used to measure the crude association among four possible courses of neck pain and HRQoL at 6 months. The neck pain trajectories over 6 months were no or mild neck pain, improving neck pain, worsening neck pain, and persistent neck pain. Finally, analysis of variance was used to examine changes in baseline to 6-month PCS and MCS scores among the four neck pain trajectory groups. The 6-month follow-up rate was 74.9%. We found an exposure-response relationship between neck pain and physical HRQoL after adjusting for age, education, arthritis, low back pain, and depressive symptomatology. Compared with participants without neck pain at baseline, those with mild (β=-1.53, 95% confidence interval [CI]=-2.83, -0.24), intense (β=-3.60, 95% CI=-5.76, -1.44), or disabling (β=-8.55, 95% CI=-11.68, -5.42) neck pain had worse physical HRQoL 6

    To identify demographic and clinical features that distinguish fibromyalgia (FM) from other chronic widespread pain. We identified 100 confirmed FM cases, 76 widespread pain controls, and 135 general controls in a random community survey of 3395 noninstitutionalized adults living in London, Ontario. FM cases were distinguished from pain controls using the 1990 American College of Rheumatology (ACR) classification criteria for FM. The mean age of FM cases was 47.8 years (range 19 to 86), the same as for pain controls; 86% of FM cases were female versus 67.1% of pain controls (p < 0.01). FM cases were less educated than general controls (p = 0.03). Male and female FM cases were similar, except females were older and reported more major symptoms (both p = 0.02). FM cases reported more severe pain and fatigue, more symptoms, more major symptoms, and worse overall health than pain controls or general controls. The most commonly reported major symptoms among FM cases were musculoskeletal pain (77.3%), fatigue (77.3%), severe fatigue lasting 24 h after minimal activity (77.0%), nonrestorative sleep (65.7%), and insomnia (56.0%). Subjects with 11-14 tender points were more similar to those with 15-18 tender points than to those with 7-10 points in 11 of 14 clinical variables. On multivariate analysis, 4 symptoms distinguished FM cases from pain controls: pain severity (p = 0.004), severe fatigue lasting 24 h after minimal activity (p = 0.006), weakness (p = 0.008), and self-reported swelling of neck glands (p = 0.01). In the general population, adults who meet the ACR definition of FM appear to have distinct features compared to those with chronic widespread pain who do not meet criteria.

    The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, and presentation of the results of case-control vaccine effectiveness studies. Vaccination status is the primary exposure of interest, but can be challenging to assess accurately and with minimal bias. Investigators should understand factors associated with vaccination as well as the availability of documented vaccination status in the study context; case-control studies may not be a valid method for evaluating vaccine effectiveness in settings where many children lack a documented immunization history. To avoid bias, it is essential to use the same methods and effort gathering vaccination data from cases and controls. Variables that may confound the association between illness and vaccination are also important to capture as completely as possible, and where relevant, adjust for in the analysis according to the analytic plan. In presenting results from case-control vaccine effectiveness studies, investigators should describe enrollment among eligible cases and controls as well as the proportion with no documented vaccine history. Emphasis should be placed on confidence intervals, rather than point estimates, of vaccine effectiveness. Case-control studies are a useful approach for evaluating vaccine effectiveness; however careful attention must be paid to the collection

    Full Text Available Abstract Background Although a rare disease, uveal melanoma is the most common primary intraocular malignancy in adults, with an incidence rate of up to 1.0 per 100,000 persons per year in Europe. Only a few consistent risk factors have been identified for this disease. We present the study design of an ongoing incident case-control study on uveal melanoma (acronym: RIFA study that focuses on radiofrequency radiation as transmitted by radio sets and wireless telephones, occupational risk factors, phenotypical characteristics, and UV radiation. Methods/Design We conduct a case-control study to identify the role of different exposures in the development of uveal melanoma. The cases of uveal melanoma were identified at the Division of Ophthalmology, University of Essen, a referral centre for tumours of the eye. We recruit three control groups: population controls, controls sampled from those ophthalmologists who referred cases to the Division of Ophthalmology, University of Duisburg-Essen, and sibling controls. For each case the controls are matched on sex and age (five year groups, except for sibling controls. The data are collected from the study participants by short self-administered questionnaire and by telephone interview. During and at the end of the field phase, the data are quality-checked. To estimate the effect of exposures on uveal melanoma risk, we will use conditional logistic regression that accounts for the matching factors and allows to control for potential confounding.

    Full Text Available Intra-capsular femoral neck fractures are seen commonly in elderly people following a low energy trauma. Femoral neck fracture has a devastating effect on the blood supply of the femoral head, which is directly proportional to the severity of trauma and displacement of the fracture. Various authors have described a wide array of options for treatment of neglected/nonunion (NU femoral neck fracture. There is lack of consensus in general, regarding the best option. This Instructional course article is an analysis of available treatment options used for neglected femoral neck fracture in the literature and attempt to suggest treatment guides for neglected femoral neck fracture. We conducted the "Pubmed" search with the keywords "NU femoral neck fracture and/or neglected femoral neck fracture, muscle-pedicle bone graft in femoral neck fracture, fibular graft in femoral neck fracture and valgus osteotomy in femoral neck fracture." A total of 203 print articles were obtained as the search result. Thirty three articles were included in the analysis and were categorized into four subgroups based on treatment options. (a treated by muscle-pedicle bone grafting (MPBG, (b closed/open reduction internal fixation and fibular grafting (c open reduction and internal fixation with valgus osteotomy, (d miscellaneous procedures. The data was pooled from all groups for mean neglect, the type of study (prospective or retrospective, classification used, procedure performed, mean followup available, outcome, complications, and reoperation if any. The outcome of neglected femoral neck fracture depends on the duration of neglect, as the changes occurring in the fracture area and fracture fragments decides the need and type of biological stimulus required for fracture union.

    Bilateral avascular necrosis (AVN) following postictal bilateral fracture neck of the femur is a rare occurrence. Here, we report a case of bilateral AVN of the femoral head following an asynchronous bilateral postictal fracture neck of the femur. A 16-year-old autistic boy presented with left hip pain following an episode of seizures and radiographs showed Delbet type II fracture neck of the left femur. This was treated by closed reduction and cancellous screw fixation and skeletal traction for 6 weeks. At 3 months, follow-up radiograph showed union of the fracture, but he had developed segmental AVN with collapse of the head. At 8 months, the patient presented with pain in the right hip following another episode of seizures and radiograph of the pelvis showed a fresh Delbet type II fracture neck of the right femur with established AVN of the left femoral head. He underwent closed reduction and cancellous screw fixation of the right hip and implant exit of the left hip. At the 6-month follow-up after this surgery, his radiograph of the pelvis showed AVN with collapse and extrusion of the femoral head on the right side as well. Literature review shows an increased risk of fracture neck of the femur among epileptics. The incidence of AVN is maximum in Delbet type I, followed by Delbet type II and type III in that order. Although there are no clear guidelines on the management of post-traumatic AVN of the femoral head, the majority have reported that most of them will eventually develop arthritis and will require total hip replacement at a later date. Upon extensive literature search, no case report of bilateral fracture neck of the femur with bilateral AVN was found and hence this case was reported.

  11. Brief communication: Paleobiological inferences on the locomotor repertoire of extinct hominoids based on femoral neck cortical thickness: The fossil great ape hispanopithecus laietanus as a test-case study.

    The relationship between femoral neck superior and inferior cortical thickness in primates is related to locomotor behavior. This relationship has been employed to infer bipedalism in fossil hominins, although bipeds share the same pattern of generalized quadrupeds, where the superior cortex is thinner than the inferior one. In contrast, knuckle-walkers and specialized suspensory taxa display a more homogeneous distribution of cortical bone. These different patterns, probably related to the range of movement at the hip joint and concomitant differences in the load stresses at the femoral neck, are very promising for making locomotor inferences in extinct primates. To evaluate the utility of this feature in the fossil record, we relied on computed tomography applied to the femur of the Late Miocene hominoid Hispanopithecus laietanus as a test-case study. Both an orthograde body plan and orang-like suspensory adaptations had been previously documented for this taxon on different anatomical grounds, leading to the hypothesis that this fossil ape should display a modern ape-like distribution of femoral neck cortical thickness. This is confirmed by the results of this study, leading to the conclusion that Hispanopithecus represents the oldest evidence of a homogeneous cortical bone distribution in the hominoid fossil record. Our results therefore strengthen the utility of femoral neck cortical thickness for making paleobiological inferences on the locomotor repertoire of fossil primates. This feature would be particularly useful for assessing the degree of orthograde arboreal locomotor behaviors vs. terrestrial bipedalism in putative early hominins.

    Full Text Available Oral mucositis (OM is a frequent and severe adverse effect of therapy against head and neck cancer. Photobiomodulation with the low-power laser is known to be effective against OM, but the diversity of protocols and the possibility of stimulating residual tumor cells are still obstacles. The present study aimed to compare two doses of laser energy delivered to the oral mucosa of patients under oncologic treatment for head and neck cancer, looking for differences in the control of mucositis, as well as in the frequency of tumoral recurrences. Fifty-eight patients undergoing radiotherapy were randomized into two groups, distinguished according to the energy delivered by laser irradiation, namely, 0.25 J and 1.0 J. The groups were compared according to frequency, severity, or duration of OM, as well as the frequency of tumoral recurrences. OM was significantly less frequent in patients receiving 1.0 J of energy, but the groups did not differ regarding severity or duration of OM. Tumoral recurrence also did not vary significantly between the groups. Photobiomodulation with a higher dose of energy (1.0 J versus 0.25 J is associated with better control of radiotherapy-induced OM and does not significantly increase the risk of neoplastic recurrence.

  13. Benign aggressive lesions of femoral head and neck: Is salvage possible?

    2018-01-01

    Full Text Available Background: Benign aggressive bone lesions of the femoral head and neck are mostly seen in young adults and warrant treatment for pain, impending fracture or established fracture, and disease clearance. It becomes challenging to treat them effectively while attempting salvage of the femoral head and yet achieving long term disease control with minimum complications. We describe our technique and experience in dealing with these lesions which can achieve the above-mentioned goals and can be easily replicated. Materials and Methods: We analyzed 15 cases of surgically treated, biopsy-proven benign, locally aggressive lesions affecting the femoral head and neck in skeletally mature individuals. All cases were treated with extended curettage through anterolateral modified Smith–Petersen approach along with tricortical iliac crest bone graft (combined with fibular graft in some cases reconstruction with or without suitable internal fixation. Results: All, except one, patients were available for follow up. The age ranged from 18 to 43 years and the follow up ranged between 24 and 124 months (average 78 months. These included aneurysmal bone cysts (9, giant cell tumors (4, and fibrous dysplasia (2. The indication was pain (8, with impending (2 or established pathological neck femur fracture (5. In all cases, there was satisfactory healing of lesion and timely rehabilitation. Nonunion, avascular necrosis or local recurrences were not seen. The MSTS functional score was good or excellent in all (range 26–29, average 28. Conclusion: Benign aggressive lesions affecting femoral head and neck in young and middle-aged adults pose a treatment challenge. A sturdy, lasting reconstruct with acceptable functional outcome and minimal recurrence rate can be achieved by salvaging the femoral head and neck using curettage and reconstruction, obviating the need for replacement at such an early age.

    Chemoradiotherapy (CRT) is becoming more widely used for head and neck cancer. However, there are conflicting theories regarding the best management options for patients with advanced nodal disease. From 1990 to 1999, we treated 96 patients with N1-N2 neck disease by concomitant CRT for organ preservation, using weekly carboplatin or a low daily dose of cisplatin, followed by a ''watch-and-see'' policy for the neck. In the present study, we retrospectively analyzed the treatment outcome in 63 of these patients who received definitive CRT for primary and neck diseases and were monitored for neck disease for more than 2 years. In 12 of the 22 (55%) N1 patients, CRT successfully controlled the neck disease. CRT was successful in 18 of the 41(44%) patients with N2 disease. In 6 (60%) of 10 patients with residual or recurrent N1 disease, salvage surgery was successful. Of the 23 patients with residual or recurrent N2 disease, salvage surgery was successful in 8 patients (35%). The group of patients who showed a clinical complete response (CCR) to CRT had an overall survival rate of 62.4% (33 patients), whereas for those with a less than complete response (< CCR), the figure was 13.3% (30 patients; P<0.001). Among the < CCR-neck group, patients who underwent neck dissection (ND) as well (n=20) did not have a significantly better overall survival than those who did not undergo ND (n=10; P=0.069). We propose a treatment plan for neck disease that involves observing the neck closely following CRT. ND should be planned only when there is evidence that neck disease exists. (author)

    There is little knowledge about the spatial distribution differences in volumetric bone mineral density and cortical bone structure at the proximal femur between femoral neck fractures and trochanteric fractures. In this case-control study, a total of 93 women with fragility hip fractures, 72 with femoral neck fractures (mean ± SD age: 70.6 ± 12.7 years) and 21 with trochanteric fractures (75.6 ± 9.3 years), and 50 control subjects (63.7 ± 7.0 years) were included for the comparisons. Differences in the spatial distributions of volumetric bone mineral density, cortical bone thickness, cortical volumetric bone mineral density, and volumetric bone mineral density in a layer adjacent to the endosteal surface were investigated using voxel-based morphometry (VBM) and surface-based statistical parametric mapping (SPM). We compared these spatial distributions between controls and both types of fracture, and between the two types of fracture. Using VBM, we found spatially heterogeneous volumetric bone mineral density differences between control subjects and subjects with hip fracture that varied by fracture type. Interestingly, femoral neck fracture subjects, but not subjects with trochanteric fracture, showed significantly lower volumetric bone mineral density in the superior aspect of the femoral neck compared with controls. Using surface-based SPM, we found that compared with controls, both fracture types showed thinner cortices in regions in agreement with the type of fracture. Most outcomes of cortical and endocortical volumetric bone mineral density comparisons were consistent with VBM results. Our results suggest: 1) that the spatial distribution of trabecular volumetric bone mineral density might play a significant role in hip fracture; 2) that focal cortical bone thinning might be more relevant in femoral neck fractures; and 3) that areas of reduced cortical and endocortical volumetric bone mineral density might be more relevant for

A randomized experimental design was used. Twenty-one healthy volunteers and 22 individuals with either traumatic or nontraumatic chronic neck pain were recruited to participate in the study. The intervention consisted of two experimental verbal persuasion conditions: Increase self-efficacy and Decrease self-efficacy. The PPT was measured using a pressure algometer, the CTh was measured using a thermo test system, and CPTo was measured by submerging the participant's hand in ice water up to the elbow joint. On three occasions, the participants reported their self-efficacy level in performing the sensory tests. In the chronic neck pain group, there were no differences in pain threshold or tolerance. There was a difference in the self-efficacy level after verbal persuasion between the experimental conditions. In the healthy control group, the CThs increased following the condition that aimed to increase self-efficacy. No other differences were observed in the healthy controls. A short verbal persuasion in the form of manipulative instructions seems to have a marginal effect on the individual's self-efficacy levels in the chronic neck pain group and a slight influence on the results of sensory testing in healthy controls.

    The purpose of this study is to analyze the combined effects of selected p53 and p73 polymorphisms and their interaction with lifestyle habits on squamous cell carcinoma of the head and neck (SCCHN) risk and progression in an Italian population. Two hundred and eighty-three cases and 295 hospital controls were genotyped for p53 polymorphisms on exon 4 (Arg72Pro), intron 3 and 6, and p73 G4C14-to-A4T14. Their association with SCCHN was estimated using a logistic regression analysis, while a multinomial logistic regression approach was applied to calculate the effect of the selected polymorphisms on SCCHN different sites (oral cavity, oropharynx, hypopharynx and larynx). We performed an haplotype analysis of the p53 polymorphisms, and a gene-gene interaction analysis for the combined effects of p73 G4C14-to-A4T14 and p53 polymorphisms. We found a significant increased risk of SCCHN among individuals with combined p73 exon 2 G4A and p53 intron 3 variant alleles (OR = 2.22, 95% CI: 1.08–4.56), and a protective effect for those carrying the p53 exon 4-p53 intron 6 diplotype combination (OR = 0.67; 95% CI: 0.47–0.92). From the gene-environment interaction analysis we found that individuals aged < 45 years carrying p73 exon 2 G4A variant allele have a 12.85-increased risk of SCCHN (95% CI: 2.10–78.74) compared with persons of the same age with the homozygous wild type genotype. Improved survival rate was observed among p53 intron 6 variant allele carriers (Hazard Ratio = 0.51 (95% CI: 0.23–1.16). Our study provides for the first time evidence that individuals carrying p53 exon 4 and p53 intron 6 variant alleles are significantly protected against SCCHN, and also shows that an additional risk is conferred by the combination of p73 exon 2 G4C14-to-A4T14 and p53 intron 3 variant allele. Larger studies are required to confirm these findings

    Aim To evaluate aerobic exercise in migraine and co-existing tension-type headache and neck pain. Methods Consecutively recruited persons with migraine and co-existing tension-type headache and neck pain were randomized into an exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 minutes, three times/week. Controls continued usual daily activities. Pain frequency, intensity, and duration; physical fitness, level of physical activity, well-being and ability to engage in daily activities were assessed at baseline, after treatment and at follow-up. Results Fifty-two persons completed the study. Significant between-group improvements for the exercise group were found for physical fitness, level of physical activity, migraine burden and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Within the exercise group, significant reduction was found for migraine frequency, pain intensity and duration, neck pain intensity, and burden of migraine; an increase in physical fitness and well-being. Conclusions Exercise significantly reduced the burden of migraine and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Exercise also reduced migraine frequency, pain intensity and duration, although this was not significant compared to controls. These results emphasize the importance of regular aerobic exercise for reduction of migraine burden.

    To assess the effectiveness of the Pilates method on pain, function, quality of life, and consumption of pain medication in patients with mechanical neck pain. The design was a randomized controlled trial, with a blinded assessor and intention-to-treat analysis. The study took place in the outpatient clinic of the rheumatology department, referral center. Sixty-four patients with chronic mechanical neck pain were randomly allocated into 2 groups: the Pilates group (PG) and control group (CG). The PG attended 2 sessions of Pilates per week, for 12 weeks. The protocol included Pilates exercises performed on a mat and on equipment and was adapted depending on the physical fitness of each participant; the repetitions varied from 6 to 12, respecting patient reports of fatigue and pain, using a single series for each exercise. The CG received only the standard pharmacological treatment. Both groups were instructed to use acetaminophen 750 mg if necessary. Patients were evaluated at baseline after 45, 90, and 180 days. We used the numerical pain scale (NPS) for pain; the neck disability index (NDI) for function, and the SF-36 questionnaire for quality of life. The groups were homogeneous at baseline, the only exception being body mass index (BMI), with the PG showing higher BMI. Regarding the assessment between groups over time (ANOVA), statistical differences were identified for pain (p Pilates method for the treatment of chronic mechanical neck pain, resulting in improvement of pain, function, quality of life, and reduction of the use of analgesics.

    Objective: To evaluate the clinical application of 64-slice spiral CT for classification of femoral neck fracture. Methods: The survey was comprised of 46 patients with femoral neck fractures detected with plain radiographs and CT images. Cases were randomly presented in 2 formats: plain radiographs and CT. Garden classification was queried. Modification of garden classification (nondisplaced vs displaced) was taken to compare with plain radiographs and CT in the study. Results: The results of classification for plain radiographs were 2 cases of Garden Ⅰ, 10 cases of Ⅱ, 22 cases of Ⅲ, and 12 cases of Ⅳ. Those for CT were 1 cases of Garden Ⅰ, 4 cases of Ⅱ, 26 cases of Ⅲ, and 15 cases of Ⅳ. CT improved the accuracy of Garden Classification (P<0.05). Conclusion: Garden classification using CT images shows good conformation with results of surgery. 64-Slic CT is better plain radiographs for Garden classification of femoral neck fracture.

    Full Text Available Introduction: Neck and thoracic trauma in children pose unforeseen challenges requiring variable management strategies. Here, we describe some unusual cases. Patients and Methods: Pediatric cases of unusual neck and thoracic trauma prospectively managed from April 2012 to March 2014 at a Level 1 trauma center were studied for management strategies, outcome, and follow-up. Results: Six children with a median age of 5.5 (range 2–10 years were managed. Mechanism of injury was road traffic accident, fall from height and other accidental injury in 2, 3 and 1 patient respectively. The presentation was respiratory distress and quadriplegia, exposed heart, penetrating injury in neck, dysphagia and dyspnea, and swelling over the chest wall in 1, 1, 1, 2 and 1 cases respectively. Injuries included lung laceration, open chest wall, vascular injury of the neck, tracheoesophageal fistula (2, and chest wall posttraumatic pyomyositis. One patient had a flare of miliary tuberculosis. Immediate management included chest wall repair; neck exploration and repair, esophagostomy, gastroesophageal stapling, and feeding jejunostomy (followed by gastric pull-up 8 months later. Chest tube insertion and total parenteral nutrition was required in one each. 2 and 4 patients required tracheostomy and mechanical ventilation. The patient with gastric pull-up developed a stricture of the esophagogastric anastomosis that was revised at 26-month follow-up. At follow-up of 40–61 months, five patients are well. One patient with penetrating neck injury suffered from blindness due to massive hemorrhage from the vascular injury in the neck and brain ischemia with only peripheral vision recovery. Conclusion: Successful management of neck and chest wall trauma requires timely appropriate decisions with a team effort.

    Full Text Available Although traumatic thyroid gland rupture or hemorrhage is usually seen in goitrous glands, injuries of the normal thyroid gland after neck trauma have rarely been described in the literature. We describe a 44-year-old man who presented with thyroid emphysema and subcutaneous emphysema (SCE that occurred after penetrating neck trauma. CT images showed complete resolution of thyroid emphysema and subcutaneous emphysema at follow-up examination. Neck injuries can be life threatening. After penetrating neck traumas, physicians should consider subtle esophageal or tracheal laceration. Thyroid emphysema can occur as the result of penetrating neck trauma. The mechanism of emphysema of the thyroid parenchyma can be explained by the thyroid gland’s presence in a single visceral compartment that encompasses the larynx, trachea and thyroid gland. We describe an unusual case of thyroid emphysema of a normal thyroid gland following a penetrating neck injury.

    We report two cases of acute cervical angina and ECG changes induced by anteflexion of the head. Cervical angina is defined as chest pain that resembles true cardiac angina but originates from cervical discopathy with nerve root compression. In these patients, Prinzmetal's angina, valvular heart disease, congenital heart disease, left ventricular aneurysm, and cardiomyopathy were excluded. After all, the patient's chest pain was reproduced by anteflexion of head, at this time, their ECGs showed nonspecific ST-T changes in the inferior and anterior leads different from the basal ECG. ECG changes returned to normal when the patient's neck moved to the neutral position. To our knowledge, these are the first cases of cervical angina associated with acute ECG changes by neck motion.

    Introduction. Cupping has been used since antiquity in the treatment of pain conditions. In this pilot study, we investigated the effect of traditional cupping therapy on chronic nonspecific neck pain (CNP) and mechanical sensory thresholds. Methods. Fifty CNP patients were randomly assigned to treatment (TG, n = 25) or waiting list control group (WL, n = 25). TG received a single cupping treatment. Pain at rest (PR), pain related to movement (PM), quality of life (SF-36), Neck Disability Index (NDI), mechanical detection (MDT), vibration detection (MDT), and pressure pain thresholds (PPT) were measured before and three days after a single cupping treatment. Patients also kept a pain and medication diary (PaDi, MeDi) during the study. Results. Baseline characteristics were similar in the two groups. After cupping TG reported significantly less pain (PR: −17.9 mm VAS, 95%CI −29.2 to −6.6; PM: −19.7, 95%CI −32.2 to −7.2; PaDi: −1.5 points on NRS, 95%CI −2.5 to −0.4; all P cupping might be an effective treatment for improving pain, quality of life, and hyperalgesia in CNP.

    femur with or without bone graft, valgus osteotomy or hip arthroplasty. We conducted a retrospective analysis of cases of nonunion of femoral neck fracture treated by transfracture abduction osteotomy (TFAO. Materials and Methods: Over a period of 35 years (1974-2008, 30 patients with nonunion of femoral neck fractures were treated with TFAO over a period of 35 years (1974-2008, All patients were less than 50 years of age. Absence of clinical and radiological signs of union after four months was considered as nonunion. Patients more than 50 years of age were excluded from the study. Union was assessed at 6 months radiologically. Limb length was measured at six months. The mean duration of femoral neck fracture was 19 months (range 4 months 10 years. Results were analyzed in terms of radiological union at six months. Average followup was five years and six months. Results: Consistent union was noted at the followup after six months in 29 cases. One case was lost to followup after five and one-half months postoperatively. However, the fracture had united in this case at the last followup. Average shortening of the limb at six months was 1.9 cm. Average neck shaft angle was 127° (range 120-145°. Five cases went into AVN but were asymptomatic. Two cases required reoperation due to back out of Moore′s pins. These were reopened and cancellous screws were inserted in the same tracks. Conclusions: Consistent union of nonunion femoral neck fracture was noted at the followup after six months in 29 cases. The major drawback of the procedure is immobilization of the patient in the hip spica for eight weeks.

    The use of acellular dermal matrices has been well described in the scientific literature since the early 1990 s and has been utilized for multiple applications in the head and neck for both aesthetic and reconstructive efforts. After systematically searching the PubMed database and following further refinement (based on the authors' inclusion and exclusion criteria), the authors identified 30 studies that provided information about patients who had undergone head and neck reconstruction with the use of acellular dermal matrix. Studies had to report quantifiable objective results in patients who were older than 1 year and younger than 90 years. The authors excluded single case reports, studies with fewer than 10 patients, and studies not published in English. The optimal material used as an implant for reconstruction possesses the following properties: facilitation of vascular ingrowth, decreased propensity to incite inflammation, biologic inertness, resistance to infection, and ease of handling. Acellular dermal matrix possesses many of these properties and is utilized in reconstructing nasal soft tissue and skeletal support, tympanic membrane, periorbital soft tissue, extraoral and intraoral defects, oropharyngeal defects, dura mater, and soft-tissue deficits from parotidectomy. Furthermore, it is used to assist in preventing Frey syndrome following parotidectomy and surgical treatment of facial paralysis. Use of acellular dermal matrix for head and neck reconstruction has expanded exponentially and is validated in many studies. Further prospective randomized control trials are warranted to further investigate the efficacy of acellular dermal matrix in head and neck reconstruction.

    Ample evidence on etiological and pathological differences between femoral neck and trochanteric fracture cases suggests the possibility of individualized treatment. There are many issues related to areal bone mineral density and other quantitative computed tomography parameters of the proximal femur. Although osteoporosis is a systemic problem, little has been reported regarding differences in bone structural parameters, including bone mineral density, between them in regions other than the proximal femur. Participants were consecutive female patients >50 years of age admitted to the Saiseikai Suita Hospital (Osaka prefecture, Japan) for their first hip fracture between January 2012 and September 2014. Cortical thickness (CoTh, mm), volumetric trabecular bone mineral density (TBD, mg/cm 3 ), and elastic modulus of trabecular bone (EMTb, GPa) were obtained as the new QUS parameters using the LD-100 system (Oyo Electric, Kyoto, Japan). The mean values of these parameters were compared between femoral neck and trochanteric fracture cases. In addition, correlations between age and each QUS parameter were investigated for each fracture type. A receiver operating characteristic (ROC) curve analysis was performed to examine the degree of effect each parameter on the fracture types. The area under the curve (AUC) for each parameter was compared to the AUC for age. There were 63 cases of femoral neck fracture (mean age, 78.2 years) and 37 cases of trochanteric fracture (mean age, 85.9 years). Mean TBD and EMTb were significantly higher for femoral neck fractures. There were significant negative correlations between QUS parameters and age for femoral neck fractures (P fractures were above those for trochanteric fractures for TBD and EMTb. AUCs were 0.72 for age, and 0.61, 0.65, and 0.65 for CoTh, TBD, and EMTb, respectively. The new QUS parameters indicated that TR fracture cases were more osteoporotic than were FN fracture cases, even at the distal radius. There might be

    Albeit the traditional opinion that advocates a routine surgical drainage for the treatment of an abscess, the case series presenting high success rates of the medical therapy alone is increasing in deep neck abscesses of childhood. This research focuses on children whose deep neck abscess fully disappeared after only medical treatment. In a retrospective study, we evaluated medical records of 12 pediatric (<18 years old) cases diagnosed with deep neck abscess or abscess containing suppurative lymphadenitis and treated with only medical therapy between 2010 and 2015 for age, gender, treatment modality, parameters related to antimicrobial agents, location of the infection, etiology, symptoms, duration of hospital stay, characteristics of the radiological and biochemical examination findings, and complications. The mean age of 10 male and two female children was 5.9 years (range, 1-17 years). Baseline and the last control's mean values of white blood cell (WBC), C-reactive protein, and erythrocyte sedimentation rate were 18,050/μL, 99.8 mg/L, 73.1 mm/h, and 8,166/μL, 34.1 mg/L, 35.3 mm/h, respectively. Contrast-enhanced neck computed tomography demonstrated an abscess in seven cases and an abscess containing suppurative lymphadenitis in five cases. The largest diameter of the abscess was 41 mm. All cases were given broad-spectrum empirical antibiotherapy (penicillin+metronidazole, ceftriaxone+metronidazole, or clindamycin). No medical treatment failure was experienced. Independent of age and abscess size, if the baseline WBC is ≤25.200/μL, if only two or less than two cervical compartments are involved, if there are no complications in the admission, and if the etiological reason is not a previous history of trauma, surgery, foreign body, and malignancy, pediatric deep neck abscess can be treated successfully with parenteral empirical wide-spectrum antibiotherapy.

    We investigated the influence of bladder neck preservation on urinary continence, quality of life and surgical margins after radical prostatectomy. A total of 208 men who presented for radical prostatectomy were randomized to complete bladder neck preservation with subsequent urethro-urethral anastomosis or to no preservation as controls. Patients with failed bladder neck preservation were not included in study. We documented objective continence by the 24-hour pad test, social continence by the number of pads per day and quality of life outcomes by the validated Incontinence Quality of Life questionnaire in a single blind setting. Cancer resection was assessed by surgical margin status. At 0, 3, 6 and 12 months mean urine loss in the control vs the bladder neck preservation group was 713.3 vs 237.0, 49.6 vs 15.6, 44.4 vs 5.5 and 25.4 vs 3.1 gm, respectively (each p <0.001). At 3, 6 and 12 months in the control vs the preservation group the social continence rate was 55.3% vs 84.2% (p <0.001), 74.8% vs 89.5% (p = 0.05) and 81.4% vs 94.7% (p = 0.027), and the quality of life score was 80.4 vs 90.3 (p <0.001), 85.4 vs 91.7 (p = 0.016) and 86.0 vs 93.8 (p = 0.001), respectively. We noted significantly less urine loss, higher objective and social continence rates, and higher quality of life scores after complete bladder neck preservation at all followup points. On multiple logistic regression analysis complete bladder neck preservation was an independent positive predictor of continence. No significant difference was found in surgical margin status between the control and bladder neck preservation groups (12.5% vs 14.7%, p = 0.65). In what is to our knowledge the first prospective, randomized, controlled, single blind trial complete bladder neck preservation during radical prostatectomy was associated with a significantly higher urinary continence rate and increased patient satisfaction without compromising resection margins.

    Full Text Available Introduction: The femoral neck fracture is a frequent pathology in the elderly population, with about of 100,000 cases per year in Brazil. The surgical treatment by internal fixation or arthroplastic hip replacement is advocated today. The non-surgical treatment is reserved for cases of exception. Objective: To compare the quality of patient postoperative life treated for femoral neck fracture by two different techniques: hip arthroplasty and internal fixation. Methods: Through the SF-36 questionnaire, we study the quality of life of 60 patients with more than 65 years, treated between 2004 and 2012 in our service. Half of the patients was submitted to internal fixation and the other half to the arthroplastic replacement. Results: Higher averages in the large majority of the parameters of the questionnaire were obtained by the group which was carried out by internal fixation, but without statistical significance in most of these differences. Some international reports indicate that patients who have suffered a fracture of the femoral neck and were treated with internal fixation may recover the quality of life they had before the fracture. Paradoxically, there is a growing trend among orthopedic surgeons to perform a hip replacement surgery in these cases. Conclusion: Further studies are needed to define which is the best surgical treatment option.

    Ankylosing spondylitis is a chronic inflammatory disorder of unknown cause that principally affects the axial skeleton. The cervical spine is also vulnerable to this disease process and the characteristic feature of cervical involvement is atlantoaxial subluxation. However, only a few cases of atlantoaxial ankylosis have been reported to date. We report a case of atlantoaxial ankylosis in a patient with ankylosing spondylitis with radiologic findings incidentally detected on neck CT scans.

    A case of radiation ulcer of the neck is reported. The patient is a 50-year-old male. He had been treated for a malignant parotid tumor 12 years earlier. Extirpation of the tumor and radical neck disection had been performed and after the operation he received radiation therapy. On 1979, erosion appeared and developed into an ulcer. On October 14, massive hemorrhage and cardiac arrest suddenly occurred. Immediate emergency treatment was administered and he was resuscitated. He was admitted to our division for the reconstruction of his ulcer. The operation was successfully performed on his ulcer using a lower trapezius myocutaneous flap. He has been followed up for 9 months. The effect of the operation is esthetically and functionally satisfactory. (author)

    Neck pain is a significant societal burden due to its high prevalence and healthcare costs. While physical activity can help to manage other forms of chronic musculoskeletal pain, little data exists on the relationship between physical activity and neck pain. The purpose of this study was to compare physical activity levels between individuals with neck pain and healthy controls, and then to relate disability, fear of movement, and pain sensitivity measures to physical activity levels in each of the two participant groups. 21 participants were recruited for each of the two participant groups (n = 42). Data collection included the use of the Neck Disability Index, the Tampa Scale for Kinesiophobia, electrocutaneous (Neurometer® CPT) and pressure stimulation (JTech algometer) for quantitative sensory testing, and 5 days of subjective (Rapid Assessment of Physical Activity) and objective (BioTrainer II) measurements of physical activity. Analysis of Variance and Pearson's Correlation were used to determine if differences and relationships exist between dependent variables both within and between groups. The results show that individuals with mild neck pain and healthy controls do not differ in subjectively and objectively measured physical activity. While participants with neck pain reported higher neck disability and fear of movement, these factors did not significantly relate to physical activity levels. Perceived activity level was related to pain threshold and tolerance at local neck muscles sites (C2 paraspinal muscle and upper trapezius muscle), whereas measured activity was related to generalized pain sensitivity, as measured at the tibialis anterior muscle site.

    To compare the difference in the short-term and long-term efficacy on cervical spondylosis of neck type between warm needling therapy in the regions of both neck and lumbus and that only in the region of neck. Eighty-one patients of cervical spondylosis of neck type were randomized into group A (41 cases) and group B (40 cases), in which 2 cases dropped out. Finally, 40 cases in the group A and 39 cases in the group B accomplished the trial. In the group A, the warm needling therapy was applied to the acupoints in the region of neck and the lumbus. Fengchi (GB 20), Tianzhu (BL 10), Neck-Bailao (EX-HN 15), Wangu (GB 12), Tianyou (TE 16) and ashi (including the tender points and code-like masses on palpation) were selected in the region of neck. Dachangshu (BL 25), Qihaishu (BL 24) and Jiaji (EX-B 2) of L5 were selected in the region of lumbus. The warm needling was applied to Fengchi (GB 20), Tianzhu (BL 10), Dachangshu (BL 25). In the group B, the warm needling therapy was applied only to the acupoints in the neck, which were same as the group A. The treatment was given once every two days, three times a week in the two groups. Separately, before treatment, 1 week after treatment, at the end of 2-week treatment and at the end of 1 month follow-up, the score of neck pain questionnaire (NPQ), the score of range of motion (ROM) in the cervical region and the score of the cervical symptoms were recorded. The efficacy at the end of treatment and in the follow-up was evaluated. Compared with those before treatment, the scores at all the observation time points were significantly improved in the two groups after treatment (all P 0.05). In the follow-up, the total effective rate was 87.5% (35/40) in the group A, better than 64.1% (25/39) in the group B ( P lumbar regions with warm needling therapy and the treatment in the local area all achieve the short-term efficacy on cervical spondylosis of neck type. For the long-term efficacy, the treatment for both neck and lumbar

    Full Text Available Abstract Simultaneous bilateral femoral neck fractures are extremely rare and associated with various conditions. Up to now Most cases had correlations with major trauma, repetitive minor trauma, seizure, parathyroid or renal dysfunction, anti-epileptic medications, seizure, etc. A 28-year-old addict man referred to us with a 10-year history of narcotic drug abuse and history of 8 months bilateral groin pain. He admitted with displaced bilateral femoral neck fracture. Because of long duration of this condition and osteonecrosis revealed on bone scan, one-staged bilateral hip hemiarthroplasty was done. A good function was noted after surgery to 4-month follow up. Up to now, have not be founded in the literature that a case of bilateral femoral neck fracture associated with narcotic drug abuse. Because of negative effects of opium or smoking on bone tissues, a simple bone pain should aware us about the risk of stress or fatigue fracture.

    To compare the usefulness of three-dimensional multislice CT angiography(CTA) and digital subtraction angiography (DSA) in the evaluation of intracranial aneurysmal neck. Nineteen patients with intracranial aneurysm (23 cases) underwent DSA and subsequent CTA. Using a multislice CT scanner and the SSD(shaded surface display) technique, clipping, cutting and the MPR technique, three-dimensional images were obtained. These were (a) external, (b) internal, from the direction of the parent artery, (c) internal, from the direction of the aneurysmal dome, and (d) an aneurysmal cutting image. The CTA findings were retrospectively compared with the DSA images. Twenty aneurysms were small and three were large. In eleven cases aneurysm neck was small, in nine it was wide, and in three it was relatively wide. For aneurysmal neck evaluation, CTA was superior to DSA in six of nine wide-neck aneurysms and all three large-sized wide-neck aneurysms. In small neck aneurysms 8 of 11 cases and in relatively wide neck all 3 cases showed similarly good images by both modalities. Of the 23 cases demonstrated by four different images, 14 cases showed the best image in internal image from parent artery direction and 6 cases showed similarly good image in both aneurysmal cutting image and internal image from parent artery direction. In the evaluation of wide neck aneurysms, 7 of 9 cases showed the best image at internal image from parent artery direction, compared with other three different images. In two cases of aneurysms, calcification was visible in the aneurysmal wall, so it was difficult to evaluate the aneurysmal neck. CTA was superior to DSA in the evaluating the intracranial aneurysmal neck. CTA maybe an additional available modality to evaluate the aneurysmal neck which is difficult to detect by the DSA. And the information of intracranial aneurysmal neck through CTA will be of value in surgical and endovascular treatment

    [Purpose] To present a case of the therapeutic reversal of a cervical kyphosis into a lordosis in a patient who presented with neck pain and headaches. [Subject and Methods] A 24-year-old male irritated his neck while dancing. Upon examination it was revealed he had an excessive, 45 mm forward head translation and a 15° cervical kyphosis from C3-C6. The patient was treated with Chiropractic BioPhysics ® methods aimed at restoring the cervical lordosis by mirror image ® , neck extension exercises, cervical extension traction, and spinal manipulative therapy. [Results] After two weeks of treatments the patient reported a complete resolution of neck pain. After 24 treatments over 10-weeks, a lateral radiograph demonstrated the restoration of a cervical lordosis and a complete reduction of forward head translation. [Conclusion] This case demonstrates that a cervical kyphosis may be reversed into a lordosis in as little as 10-weeks by specific care incorporating cervical extension protocols. This case also supports the biomechanical literature that suggests those with cervical kyphosis may be predisposed to spinal injury. We suggest that correcting even asymptomatic patients with obvious cervical spine deformity should be accomplished prior to future injury and/or degenerative changes.

    We evaluated the usefulness of simultaneous intra-arterial chemotherapy and radiotherapy for oropharyngeal cancer without neck metastasis. Fifty eight cases without neck metastasis out of previously untreated 117 patients with oropharyngeal cancer treated at National Kyushu Cancer Center from 1972 to 1995 were examined. Seventeen patients were in T1, 27 in T2, 10 in T3, 4 in T4. Fourteen patients of 58 patients were treated by simultaneous intra-arterial chemotherapy and radiation therapy. The 5-year survival rate by Kaplan-Meier method for intra-arterial infusion group and non intra-arterial infusion group were 86% and 71%, respectively. Thirty one patients were treated with irradiation without surgery. In 31 cases without surgery, the 5-year survival rate for intra-arterial infusion group (13 cases) was 85%, while that for non intra-arterial infusion group (18 cases) was 60%, and the local control rate for intra-arterial infusion group is 92%, while that for non intra-arterial infusion group was 56%. Simultaneous intra-arterial chemotherapy and radiotherapy for oropharyngeal cancer without neck metastasis is useful to improve the prognosis with preserving the function. (author)

    Acute and chronic spinal symptoms such as neck pain may limit flying performance significantly and disqualify the pilot from flight duty. Mechanical neck pain is very common among pilots because of their exposure to vibration, +GZ forces, helmet weight, poor neck posture during air combat maneuvers, previous neck injuries, and poor treatment plans for such injuries. Successful treatment of such injuries requires appropriate therapeutic procedures as well as an aeromedical assessment. The aim of this case study was to demonstrate the benefits of conservative procedures such as spinal manipulation and mobilization therapy (SMMT) and exercise therapy (ET) in treating chronic mechanical neck pain in an Iranian commercial helicopter pilot. A 36-yr-old male patient presented to the clinic with moderate, intermittent nonradicular chronic neck pain and limited range of motion over a 2-yr period. The patient was treated with cervical and upper thoracic SMMT followed by home ET for 5 wk. After this period, the patient reported significant recovery and improvement in range of motion in his neck. Mechanical neck pain is very common among helicopter pilots. Although Air Force and Navy waiver guides recommend nonsteroidal anti-inflammatory medications as well as SMMT and ET, there are currently very few published studies that examine the benefits of manual and exercise therapy for treating mechanical neck pain in commercial and military pilots. Based on the results of this study, it seems that SMMT and ET may be a safe and effective in treatment of uncomplicated mechanical neck pain in helicopter pilots. Alagha B.

    Background: There are few population-based studies on the epidemiology of neck pain in the general population. Purpose: To synthesize the findings of two large population-based studies of the epidemiology of neck pain and whiplash-associated disorders from the province of Saskatchewan, Canada. Study Design and Methods: We conducted two population-based cohort studies of neck pain and its related disability in Saskatchewan, Canada. First, the Saskatchewan Health and Back Pain Survey was designed to determine the prevalence and factors associated with neck pain in randomly selected adults. Second, we conducted a cohort study of the incidence and prognosis of whiplash and studied whether a change in the insurance system from tort to no-fault was related to a reduction in the number of whiplash claims and faster recovery. Results: In 1995, the six-month prevalence of neck pain was 54.2% and 4.6% of adults experienced disabling neck pain in the previous six-months. Neck pain was associated with education, comorbidities, smoking, self-reported general health and a history of neck injury in a motor vehicle collision. The incidence of treated and/or compensated whiplash injury was estimated at 834/100,000 adults in 1994, and dropped by 28% to 598/100,000 adults in 1995, after tort reform. Compared to tort, the median time-to-recovery was more than 230 days faster under no-fault. The strongest predictors of recovery were age, gender, education, injury severity, lawyer involvement and type of initial care provider. Conclusion: Neck pain is a public health problem. The incidence and prognosis of whiplash injuries are greatly influenced by compensation for pain and suffering, legal factors, injury severity and sociodemographic characteristics. Overall, neck pain is a multifaceted disabling problem that deserves more attention. When treating patients with neck pain, clinicians need to recognize that it is more than a physical problem and that its prognosis is influenced by

    Case-control study designs are commonly used. However, many published case-control studies are not true case-controls and are in fact mislabeled. The purpose of this study was to identify all case-control studies published in the top three plastic surgery journals over the past 10 years, assess which were truly case-control studies, clarify the actual design of the articles, and address common misconceptions. MEDLINE, Embase, and Web of Science databases were searched for case-control studies in the three highest-impact factor plastic surgery journals (2005 to 2015). Two independent reviewers screened the resulting titles, abstracts, and methods, if applicable, to identify articles labeled as case-control studies. These articles were appraised and classified as true case-control studies or non-case-control studies. The authors found 28 articles labeled as case-control studies. However, only six of these articles (21 percent) were truly case-control designs. Of the 22 incorrectly labeled studies, one (5 percent) was a randomized controlled trial, three (14 percent) were nonrandomized trials, two (9 percent) were prospective comparative cohort designs, 14 (64 percent) were retrospective comparative cohort designs, and two (9 percent) were cross-sectional designs. The mislabeling was worse in recent years, despite increases in evidence-based medicine awareness. The majority of published case-control studies are not in fact case-control studies. This misunderstanding is worsening with time. Most of these studies are actually comparative cohort designs. However, some studies are truly clinical trials and thus a higher level of evidence than originally proposed.

    Seven cases of delayed airway stenosis after radiotherapy for early staged head and neck cancers during 1989 and 1999 were evaluated (aged 54-77 yrs, 6 male and a female). The cases included five glottic laryngeal cancers (T1a, T1b, and three T2), a subglottic laryngeal cancer, and an unknown origin, but strongly suspected laryngeal cancer, with neck metastasis. Radio injury was found from 3 months to 47 months after radiotherapy. {sup 60}Co for radiotherapy was used in all seven cases, although {sup 60}Co radionuclide was changed to Liniac in 1997. The total dose was 60 Gy for 3 cases, and 70 Gy for 4 cases. Tracheostomy was performed in 3 cases due to bilateral vocal cord impairment. Background, treatment, and response to radiotherapy were compared to those of 90 patients of a control group with early staged laryngeal cancer who did not fail radiation injury during the same period. As a result, radionuclide ({sup 60}Co), total dose, cervical surgery, antiinflammatory drugs, laryngeal edema during radiotherapy were risk factors.

    Full Text Available Abstract Introduction Neuroglial heterotopia, heterotopic brain tissue, or differentiated neural tissue outside the cranial vault is uncommon, and these anomalies most commonly occur in the nasal cavity. Case presentation We report a case of rare pure cystic heterotopic brain tissue in a two-month-old Caucasian baby girl that presented as a large cystic neck mass and was confused with a cystic hygroma. Her mother reported a progressive increase in the size of this swelling and mild respiratory difficulty when the girl was sleeping. A computed tomography scan of the brain and neck showed a large heterogeneous mass extending from the base of the skull to the left submandibular region; a cystic component was also noted. Our patient under went total excision of the cystic mass and prevention of airway obstruction by a left submandibular approach. The final gross pathology diagnosis was heterotopic brain tissue. Conclusions Pure cystic neck heterotopic brain tissue lesions are very uncommon, and a preoperative diagnosis of this lesion is difficult. Brain heterotopia is a rare, benign condition that should be considered in the differential diagnosis of the neonatal head and neck mass.

    Full Text Available Background: Chronic periodontitis is an inflammatory disease of the supporting structures of the tooth. One of the important non-oral risk factors for periodontitis is psychosocial stress and depression. Depression affects oral health by affecting the immune system through its effects on hypothalamic pituitary axis system. Periodontal inflammatory surface area (PISA is a system used to assess inflammatory burden in the periodontal tissue. Aim: The aim of this study is to assess the relationship between PISA and depression. Settings and Design: The design of the study is case-control study. Materials and Methods: The study design is a case-control study with forty patients each in case and control groups. The periodontal inflammatory level was assessed by PISA system and the levels of depression was assessed by using Beck's Depression Inventory (BDI. Statistical Analysis: Student's t-test was used to compare PISA and BDI scores. The BDI score (mean ± standard deviation [SD] for controls was 12.75 ± 6.82 compared to 22.73 ± 4.40 for the cases. The comparison (t = 7.78 was statistically significant at P < 0.0001. The PISA score (mean ± SD for controls was 210.47 ± 76.80 compared to the PISA score of 1069.50 ± 204.21 for cases which was statistically significant (t = 24.90; P < 0.0001. Results: Significantly higher BDI scores were observed in patients with chronic periodontitis than healthy controls. Conclusion: This study clearly reveals a significant association between the severity of depression and inflammatory burden.

    Neck pain is a large clinical problem where reorganized trunk and axioscapular muscle activities have been hypothesised contributing to pain persistence and pain hypersensitivity. This study investigated the effects of bilateral experimental neck pain on trunk and axioscapular muscle function and pain sensitivity. In 25 healthy volunteers, bilateral experimental neck pain was induced in the splenius capitis muscles by hypertonic saline injections. Isotonic saline was used as control. In sitting, subjects performed slow, fast and slow-resisted unilateral arm movements before, during and after injections. Electromyography (EMG) was recorded from eight shoulder and trunk muscles bilaterally. Pressure pain thresholds (PPTs) were assessed bilaterally at the neck, head and arm. Data were normalized to the before-measures. Compared with control and post measurements, experimental neck pain caused (1) decreased EMG activity of the ipsilateral upper trapezius muscles during all but slow-resisted down movements (p neck pain reorganized axioscapular and trunk muscle activity together with local hyperalgesia and widespread hypoalgesia indicating that acute neck pain immediately affects trunk and axioscapular function which may affect both assessment and treatment. Bilateral clinical neck pain alters axioscapular muscle coordination but only effects of unilateral experimental neck pain has been investigated. Bilateral experimental neck pain causes task-dependent reorganized axioscapular and trunk muscle activity in addition to widespread decrease in pressure pain sensitivity. © 2016 European Pain Federation - EFIC®.

    Poor oral hygiene has been proposed to contribute to head and neck cancer (HNC) risk, although causality and independency of some indicators are uncertain. This study investigates the relationship of five oral hygiene indicators with incident HNCs. In a pooled analysis of 8925 HNC cases and 12 527 controls from 13 studies participating in the International Head and Neck Cancer Epidemiology Consortium, comparable data on good oral hygiene indicators were harmonized. These included: no denture wear, no gum disease (or bleeding), oral hygiene indicator and cumulative score on HNC risk, adjusting for tobacco smoking and alcohol consumption. Inverse associations with any HNC, in the hypothesized direction, were observed for cancer sites, especially for tooth brushing and dentist visits. The population attributable fraction for ≤ 2 out of 5 good oral hygiene indicators was 8.9% (95% CI 3.3%, 14%) for oral cavity cancer. Good oral hygiene, as characterized by few missing teeth, annual dentist visits, and daily tooth brushing, may modestly reduce the risk of HNC. © The Author 2016.

    2014-08-15

    Case-chaos methodology is a proposed alternative to case-control studies that simulates controls by randomly reshuffling the exposures of cases. We evaluated the method using data on outbreaks in Sweden. We identified 5 case-control studies from foodborne illness outbreaks that occurred between 2005 and 2012. Using case-chaos methodology, we calculated odds ratios 1,000 times for each exposure. We used the median as the point estimate and the 2.5th and 97.5th percentiles as the confidence interval. We compared case-chaos matched odds ratios with their respective case-control odds ratios in terms of statistical significance. Using Spearman's correlation, we estimated the correlation between matched odds ratios and the proportion of cases exposed to each exposure and quantified the relationship between the 2 using a normal linear mixed model. Each case-control study identified an outbreak vehicle (odds ratios = 4.9-45). Case-chaos methodology identified the outbreak vehicle 3 out of 5 times. It identified significant associations in 22 of 113 exposures that were not associated with outcome and 5 of 18 exposures that were significantly associated with outcome. Log matched odds ratios correlated with their respective proportion of cases exposed (Spearman ρ = 0.91) and increased significantly with the proportion of cases exposed (b = 0.054). Case-chaos methodology missed the outbreak source 2 of 5 times and identified spurious associations between a number of exposures and outcome. Measures of association correlated with the proportion of cases exposed. We recommended against using case-chaos analysis during outbreak investigations. © The Author 2014.

    Introduction: Elective treatment of the clinically node-negative neck by radiation results in excellent control rates. However, radiation therapy with its organ-preserving properties is not without morbidity. Side effects of elective neck irradiation are mainly due to damage of the major and minor salivary glands, resulting in the dry mouth syndrome. Given that RT is the preferred treatment modality in case of elective treatment of the neck in many institutions, it is of utmost importance to try and reduce the associated sequelae of RT. Material and Methods: With the introduction of CT-planning systems and the development of 3D conformal radiation therapy (3D CRT) techniques, it has become feasible to deliver adequate doses of radiation to the target (neck) and at the same time saving (parts of) the salivary glands from doses beyond tolerance. A prerequisite for these techniques is that they require a precise knowledge of the target (i.e., of the elective neck) on CT. To be able to correlate borders of the surgical levels in the neck (I-VI) with structures seen on CT, an anatomical study, using two fixed (phenol, formaldehyde) human cadavers, was performed. Subsequently, the 6 potential lymph node regions in the neck on CT were defined. Results and Discussion: The reference for the current 3D CT-based definition of the lymph node regions in the neck is the official report of the American Academy of Otolaryngology, describing, based on surgical anatomy, the lymph node groups in the neck by Levels I-VI. The present investigation depicts reproducible landmarks on transversal CT images, corresponding to anatomical reference structures known from surgical levels (I-VI) and, this way, CT-based lymph node regions (1-6) were constructed

    Thickness of the lower trapezius muscle in patients with neck pain has not been established. We examined the thickness of the lower trapezius muscle in patients with and without unilateral neck pain. Twenty women with unilateral (right) neck pain and 20 matched controls participated in the study. Thickness of the lower trapezius muscles was measured bilaterally at rest (0 ° and 120 ° of shoulder abduction) and during contraction (120 ° of shoulder abduction) using ultrasound imaging. The neck pain group had smaller thickness of the lower trapezius muscle on the painful side compared with controls both at rest and during contraction (P  0.05). Patients with neck pain had smaller thickness of the lower trapezius muscle on the painful side compared with healthy controls. Muscle Nerve 54: 439-443, 2016. © 2015 Wiley Periodicals, Inc.

    Neck pain is considered to be a major health problem in modern societies. Many previous studies found that certain occupations are related to this problem or are associated with the risk of developing it in future. Although the pain is caused by mechanical factors, it may progress to a serious problem and give rise to other abnormal symptoms such as vertigo, headache, or migraine. To investigate the prevalence of neck pain among the cabin crew of Saudi Airlines. A cross-sectional study was carried out on the available Saudi Airlines cabin crews in King Fahad Airport during our visits, using questionnaires and measurements of several parameters. Neck Pain Questionnaires were distributed to the cabin crews on Saudi Airlines and assessment sheets were completed by all participants of the study to evaluate the prevalence and distribution of neck pain. Physical therapy examination of neck motions in different directions and specific tests were performed by all the participants to identify any symptoms. Using these data the prevalence of neck pain among the cabin crews was calculated. Collected data were analyzed statistically using SPSS software calculating the mean, median, and score of the questionnaire. According to the scoring system of the study, 31 (30.09%) of 105 cabin crew staff of Saudi Airlines had neck pain. Our study confirmed a positive correlation between this occupation and neck pain, and in fact found that according to the results of logistic regression analysis, this occupation is the only significant factor that affects the positive compression test. The prevalence of neck pain among the cabin crews of Saudi Airlines was emphasized. The results show a high prevalence of neck pain in the participants of the study, with most cases appearing to run a chronic - episodic course. Further research is needed to help us understand more about the long-term course of neck pain and its broader outcomes and impacts.

The aim of this study was to assess the safety and efficacy of endovascular embolization for acute hemorrhage in patients with head and neck cancers.Materials and MethodsData were retrospectively collected from patients with head and neck cancers who underwent endovascular embolization to treat acute hemorrhage. The primary endpoint was the rate of immediate control of hemorrhage during the first 24 h after embolization. The secondary endpoints were technical or clinical complications, rate of re-hemorrhage 24 h after the procedure, time from embolization to re-hemorrhage, hospitalization time, mortality rate, and time from embolization to death.ResultsFifty-one patients underwent endovascular embolization. The primary endpoint was achieved in 94% of patients. The rate of technical complications was 5.8%, and no clinical complication was observed. Twelve patients (23.5%) had hemorrhage recurrence after an average time of 127.5 days. The average hospitalization time was 7.4 days, the mortality rate during the follow-up period was 66.6%, and the average time from embolization to death was 132.5 days.ConclusionEndovascular embolization to treat acute hemorrhage in patients with head and neck cancers is a safe and effective method for the immediate control of hemorrhage and results in a high rate of hemorrhage control. Larger studies are necessary to determine which treatment strategy is best for improving patient outcomes.

    Although it is widely accepted that aspirin will increase the risk of intra- and post-operative bleeding, clinical studies have not consistently supported this assumption. We aimed to assess the effect of pre-operative aspirin on blood loss and transfusion requirements in patients undergoing emergency fixation of femoral neck fractures. A prospective case-control study was undertaken in patients presenting with femoral neck fractures. Parameters recorded included intra-operative blood loss, post-operative blood loss, transfusion requirements and peri-operative reduction in haemoglobin concentration. Of 89 patients presenting with femoral neck fractures 32 were on long-term aspirin therapy. Pre-operative aspirin ingestion did not significantly affect peri-operative blood loss, or change in haemoglobin concentration or haematocrit. However those patients taking aspirin pre-operatively had a significantly lower haemoglobin concentration and haematocrit and were more likely to be anaemic at presentation than those who were not receiving aspirin. Patients taking aspirin were also more likely to receive blood transfusion post-operatively.

    Self-induced hypoxia has been reported particularly in adolescents, and it can result in neurological injury. Here, we present a case of electroencephalogram (EEG) abnormalities induced by habitual neck compression differentiated from epileptic seizures by Tc-99m HMPAO SPECT. A 19-year-old male was admitted for evaluation of recurrent generalized tonic-clonic seizures. No interictal EEG abnormality was detected; however, abnormal slow delta waves were found immediately after habitual right neck compression. To differentiate EEG abnormalities due to a hemodynamic deficit induced by habitual neck compression from an epileptic seizure, Tc-99m HMPAO SPECT was performed immediately after right carotid artery compression. Abnormal delta waves were triggered, and cerebral hypoperfusion in the right internal carotid artery territory was detected on Tc-99m HMPAO SPECT. The slow delta wave detected on the EEG resulted from the cerebral hypoperfusion because of the habitual neck compression.

    The purpose of this investigation was to identify modifiable risk factors for the development of first-onset chronic neck pain among an inception cohort of healthy individuals working in a high-risk occupation. Candidate risk factors identified from previous studies were categorized into psychosocial, physical, and neurophysiological domains, which were assessed concurrently in a baseline evaluation of 171 office workers within the first 3 months of hire. Participants completed monthly online surveys over the subsequent year to identify the presence of chronic interfering neck pain, defined as a Neck Disability Index score ≥5 points for 3 or more months. Data were analyzed using backward logistic regression to identify significant predictors within each domain, which were then entered into a multivariate regression model adjusted for age, sex, and body mass index. Development of chronic interfering neck pain was predicted by depressed mood (odds ratio [OR] = 3.36, 95% confidence interval [CI] = 1.10-10.31, P = .03), cervical extensor endurance (OR = .92, 95% CI, .87-.97, P = .001), and diffuse noxious inhibitory control (OR = .90, 95% CI, .83-.98, P = .02) at baseline. These findings provide the first evidence that individuals with preexisting impairments in mood and descending pain modulation may be at greater risk for developing chronic neck pain when exposed to peripheral nociceptive stimuli such as that produced during muscle fatigue. Depressed mood, poor muscle endurance, and impaired endogenous pain inhibition are predisposing factors for the development of new-onset chronic neck pain of nonspecific origin in office workers. These findings may assist with primary prevention by allowing clinicians to screen for individuals at risk of developing chronic neck pain. Copyright © 2015 American Pain Society.

    There is a paucity of research that investigates therapeutic interventions of patients with concurrent head and neck lymphedema and temporomandibular dysfunction (TMD). The purpose of this case report is to describe the management and outcomes of a patient with head and neck lymphedema and TMD using a multimodal physical therapy approach. A 74-year-old male with a past medical history of head and neck lymphedema and TMD was referred to physical therapy with chief complaints of inability to open his mouth in order to eat solid food, increased neck lymphedema, temporomadibular joint pain, and inability to speak for prolonged periods of time. The patient was treated for three visits over 4 weeks. Treatment included complete decongestive therapy (CDT), manual therapy, therapeutic exercise, and a home exercise program. Upon discharge, the patient had improved mandibular depression, decreased head and neck lymphedema, improved deep neck flexor endurance, decreased pain, and improved function on the Patient Specific Functional Scale (PSFS). Utilization of a multimodal physical therapy approach to treat a patient with a complex presentation yielded positive outcomes. Further research on outcomes and treatment approaches in patients with TMD and head and neck lymphedema is warranted.

    Branchial cleft cyst is the most common lateral neck cyst ; the vast majority are of the second branchial cleft origin. This presumably reflects the greater depth and longer persistence of the second cleft, compared with the first, third, and fourth clefts. We experienced a 49-year-old male whose chief complaint was a abnormal mass of the cleft parotid gland area and neck. As a result of careful analysis of clinical, radiological, and histopathological findings. We diagnosed it as a second branchial cleft cyst in the neck and obtained results as follows: 1. In clinical examination, there was a 10 X 15 cm sized, fluctuant painful mass in the left neck and parotid area. 2. In radiographic examination, a low echogenic mass with internal cystic change in the inferior parotid gland area was noted sonographically. Computed tomograph showed a 3 X 4 cm sized, well-defined cystic mass with heterogenous solid component in the anterior border of sternocleidomastoid muscle. MRI revealed 5 X 6 cm sized, well-marginated multiseparated mass in the same area. 3. In histopathological examination, lining of cyst was stratified squamous epithelium with typical lymph node pattern and inflammatory cell infiltration.

    The purpose of this study was to assess whether a positron emission tomography (PET)-directed policy remains appropriate for managing neck nodes (N3; >6 cm) in head and neck squamous cell carcinoma (HNSCC). All patients with N3 (>6 cm) HNSCC treated with definitive chemoradiotherapy (CRT) at our institution between 2005 and 2012 were included in the analysis. Patients underwent PET assessment before and 12 weeks after CRT. Neck dissections were performed for PET-avid residual nodal abnormalities after complete response at the primary site. Rate of isolated nodal failure (INF) was the primary outcome. Median follow-up from diagnosis for 33 patients was 30 months (range, 6-76 months). INF occurred in 2 patients (6%) with neck dissections performed in 4 cases (12%). First failure was predominantly distant metastatic (10; 30%). The rate of INF remains low when following a PET-directed neck management policy after definitive CRT for N3 (>6 cm) HNSCC. Copyright © 2013 Wiley Periodicals, Inc.

    Radiation therapy in head and neck malignancy may trigger mucositis poorly controlled by nonsteroidal antiinflammatory drugs (NSAIDs). Having already reported early opioid efficacy in radiation-induced mucositis pain in head and neck cancer, we discuss whether this resulted in severe side effects and opioid addiction. Of 11 persons (26.2%) with nausea, 3 could not tolerate opioid. Of 33 (78.6%) with constipation, all were controlled by purgatives. Seven had mild sleepiness. None had severe opioid side effects in radiation-induced mucositis pain treatment, but I showed opioid dependence after 128-days opioid administration. While opioid administration in radiation-induced mucositis pain may not cause addiction, lomg-term opioid use should be carefully monitored. (author)

  15. Neck pain and postural balance among workers with high postural demands - a cross-sectional study

    Science.gov (United States)

    2011-01-01

    Background Neck pain is related to impaired postural balance among patients and is highly prevalent among workers with high postural demands, for example, cleaners. We therefore hypothesised, that cleaners with neck pain suffer from postural dysfunction. This cross-sectional study tested if cleaners with neck pain have an impaired postural balance compared with cleaners without neck pain. Methods Postural balance of 194 cleaners with (n = 85) and without (N = 109) neck pain was studied using three different tests. Success or failure to maintain the standing position for 30 s in unilateral stance was recorded. Participants were asked to stand on a force platform for 30 s in the Romberg position with eyes open and closed. The centre of pressure of the sway was calculated, and separated into a slow (rambling) and fast (trembling) component. Subsequently, the 95% confidence ellipse area (CEA) was calculated. Furthermore a perturbation test was performed. Results More cleaners with neck pain (81%) failed the unilateral stance compared with cleaners without neck pain (61%) (p neck pain in comparison with cleaners without neck pain in the Romberg position with eyes closed, but not with eyes open. Conclusions Postural balance is impaired among cleaners with neck pain and the current study suggests a particular role of the slow component of postural sway. Furthermore, the unilateral stance test is a simple test to illustrate functional impairment among cleaners with concurrent neck and low back pain. Trial registration ISRCTN96241850 PMID:21806796

    Small oropharyngeal carcinomas with advanced neck metastases (stage N2 or greater) are common. Patients with small T with large N oropharyngeal carcinoma have high rates of local control but lower rates of regional control when treated with chemoradiotherapy. Clinical assessment after chemoradiotherapy cannot ensure the absence of neck disease. In the last 5 years, we have treated patients with T1-2 with N2-3 oropharyngeal carcinoma with weekly docetaxel radiotherapy followed by planned neck dissection (PND). Our objectives were to clarify the pathologically complete response (CR) rate of neck metastasis after weekly docetaxel radiotherapy, to identify the clinical predictor of residual neck disease, and to determine the mobidity of planned neck dissection. After chemoradiotherapy, all 12 patients had a complete response at the primary site. We conducted 15 neck dissections. Of these, 6 (40%) had positive nodes. The pathological CR rate of neck metastasis was 58.3%, whereas overall 2-year neck control rate was 91.7%. These findings lend support to the role of PND after chemoradiotherapy in N2-3 neck disease. After chemoradiotherapy, clinical parameters including TN status, feasibility of chemoradiotherapy, largest lymph node size or size reduction in MRI, did not identify patients with residual neck disease. We conducted selective neck dissection (SND) in 80% of patients. SND as PND appears to be appropriate in this group of patients because of the low incidence of complications. A further cohort study including the comparison of PND nonenforcement group is necessary to clarify the validity of the addition of PND in weekly docetaxel radiotherapy. (author)

    The authors believe that open access to the submental region, platysmaplasty, and wide skin undermining provide the most long-lasting results in neck rejuvenation, and sought to evaluate this hypothesis by reviewing their neck-lift patients. The authors performed a retrospective chart review of their experience with neck-lift procedures and patients who underwent a secondary procedure. Patient age, sex, initial technique, visible neck deformities, and reasons for revision were assessed. Photographs were used to assess the features of persistent or recurrent neck-lift deformity and techniques to correct them. Of 1089 neck lifts reviewed, 101 patients underwent secondary or revision procedures (approximately 10 percent of total). The average patient age was 57.4 years, 95 percent were women, and secondary procedures were performed 10.3 years after the first procedure. Seventy percent of the revisions were of the authors' own primary neck lifts, and all of these after 10 years. The most common aesthetic deformities--recurrent platysmal bands (87 percent), persistent/recurrent jowling (48 percent), fat malposition/irregularities (10 percent), and vertical band deformity (8 percent)--were most often corrected with open platysmaplasty and medial or lateral plication and skin redraping. All patients had their submental region opened in the secondary procedure. All secondary operations were performed at least 10 years after primary surgery. The authors believe their technique of open submental neck access and platysmal approximation in patients with medial bands provides long-lasting results. The authors use precise preoperative evaluation, recontouring of neck fat irregularities, opening of the submental region with platysmaplasty, drains, and strict hemostasis. Therapeutic, IV.

    Full Text Available Background: Aim of the study was to find the risk factors leading to Anemia in pregnancy. The main objective was to study the various sociodemographic factors leading to anemia. And to assess the knowledge about anemia among study participants. Material and methods: The present Case control study was carried out at Primary Health Centre, to determine the risk factors leading to anemia in pregnancy. A total of 308 pregnant females were registered. Among them two groups were made, group I cases and group II controls. Each group had 50 cases each. Laboratory test were done and females having hemoglobin less than 11mg/dl were considered anemic. Anemic females were considered cases and females having Hb >11mg/dl were considered controls. Data analysis was done using SPSS software. Results: The overall mean haemoglobin (Hb was 11.55g/dL in controls, whereas it was seen that among the cases it was 9.58g/dL.It would seem that diet, family size, education, social class, gravida and parity are associated with anemia in pregnancy. Conclusion: After adjusting for all the possible covariates there seems to be significant association between Hb levels and age group, education level, family size, diet, gravida and parity.

    The authors describe the first case of spindle cell lipoma of the posterior neck invading the upper cervical spinal canal and the posterior cranial fossa. Spindle cell lipoma is an extremely rare variant of benign lipoma. It usually occurs as a solitary subcutaneous well-circumscribed lesion in the posterior neck or shoulders of adult men. Local aggressiveness is unusual. This 61-year-old man presented with an increased left cerebellar syndrome and headaches. He also had a posterior neck tumefaction, which had been known about for a long time. Computed tomography and MR imaging studies revealed a voluminous mass extending to the upper cervical canal and posterior cranial fossa and eroding the neighboring bones. The lesion was well delimited, and contrast enhancement was intense and heterogeneous. The tumor, which had initially developed under the muscles of the posterior neck, was totally resected. Histological assessment revealed numerous fat cells with spindle cells secreting collagen. The large size of the tumor and the submuscular location, bone erosion, and compression of the CNS were unusual in this rare subtype of benign adipose tumor. Its presentation could simulate a sarcoma.

    The purpose of this study is to report the results of megavoltage irradiation with cobalt-60 in 23 previously unreported cases of extramedullary plasmacytoma of the head and neck. It has been found that 3500 cGy (rad) in three weeks provides good local control of disease with minimal morbidity and a significant proportion do not go on to multiple myeloma. Prognostic factors of significance with respect to subsequent development of multiple myeloma include site and presence or absence of bone destruction. The presence or absence of an M protein peak appears to be of no significance. (author)

    This was a randomized controlled pilot trial to evaluate the effectiveness of cupping therapy for neck pain in video display terminal (VDT) workers. Forty VDT workers with moderate to severe neck pain were recruited from May, 2011 to February, 2012. Participants were randomly allocated into one of the two interventions: 6 sessions of wet and dry cupping or heating pad application. The participants were offered an exercise program to perform during the participation period. A 0 to 100 numeric rating scale (NRS) for neck pain, measure yourself medical outcome profile 2 score (MYMOP2 score), cervical spine range of motion (C-spine ROM), neck disability index (NDI), the EuroQol health index (EQ-5D), short form stress response inventory (SRI-SF) and fatigue severity scale (FSS) were assessed at several points during a 7-week period. Compared with a heating pad, cupping was more effective in improving pain (adjusted NRS difference: -1.29 [95% CI -1.61, -0.97] at 3 weeks (p=0.025) and -1.16 [-1.48, -0.84] at 7 weeks (p=0.005)), neck function (adjusted NDI difference: -0.79 [-1.11, -0.47] at 3 (p=0.0039) and 7 weeks (pcupping and 0.91 [0.86, 0.91] with heating pad treatment, p=0.0054). Four participants reported mild adverse events of cupping. Two weeks of cupping therapy and an exercise program may be effective in reducing pain and improving neck function in VDT workers.

    The study aims to present our experience of the clinical course and management of deep neck infection and try to determine if the characteristics of this kind of infection were similar between the children and adults in southern China.Patients diagnosed with deep neck infection in the Division of Otolaryngology in the First Affiliated Hospital of Sun Yat-sen University between January 2002 and December 2011 were screened retrospectively for demographic characteristics, presenting symptoms, antibiotic therapy before admission, the history of antibiotics abuse, leucocyte count, etiology, bacteriology, disease comorbidity, imaging, treatment, complications, and outcomes.One hundred thirty patients were included and 44 (33.8%) were younger than 18 years old (the children group), 86 patients (66.2%) were older than 18 years old (the adults group). Fever, trismus, neck pain, and odynophagia were the most common symptoms in both groups. Forty children (90.9%) and 49 adults (57.0%) had been treated with broad-spectrum antibiotic therapy before admission. Thirty one children (70.5%) and 24 adults (27.9%) had a history of antibiotics abuse. In children group, the site most commonly involved was the parapharyngeal space (18 patients, 40.9%). In adults group, the site most commonly involved was multispace (30 patients, 34.9%). In children group, the most common cause was branchial cleft cyst (5 patients, 11.4%) and the cause remained unknown in 31 patients (70.5%). In adults group, the most common cause was pharyngeal infection (19 patients, 22.2%). All of the 27 patients with associated disease comorbidity were adults and 17 were diabetes mellitus (DM). Streptococcus viridans was the most common pathogen in both children and adults groups. Eighty six (66.2%) underwent surgical drainage and complications were found in 31 patients (4 children, 27 adults).Deep neck infection in adults is easier to have multispace involvement and lead to complications and appears to be more

    Full Text Available Chronic hemoglobinopathies like thalassemia are associated with many osteopathies like osteoporosis. Methods. This observational study was carried out to compare the bone mineral density (BMD in transfusion dependent thalassemics with that of healthy controls. Thirty-two thalassemia patients, aged 2–18 years, and 32 age and sex matched controls were studied. The bone mineral concentration (BMC and BMD were assessed at lumbar spine, distal radius, and neck of femur. Biochemical parameters like serum calcium and vitamin D levels were also assessed. Results. The BMC of neck of femur was significantly low in cases in comparison to controls. We also observed significantly lower BMD at the lumbar spine in cases in comparison to controls. A significantly positive correlation was observed between serum calcium levels and BMD at neck of femur. Conclusion. Hence, low serum calcium may be used as a predictor of low BMD especially in populations where incidence of hypovitaminosis D is very high.

    Purpose: For node-negative supraglottic carcinoma of the larynx, radiotherapy with surgery in reserve commonly provides very good results in terms of both local control and survival, while preserving function. However uncertainty exists over the treatment of the node-negative neck. Elective whole neck radiotherapy, while effective, may be associated with significant morbidity. The purpose of this study was to examine our practice of treating a modest size, fixed field to a high biologically effective dose and compare it with the patterns of recurrence from other centers that use different dose/volume approaches. Methods and Materials: Over a 10-year period 331 patients with node-negative supraglottic carcinoma of the larynx were treated with radiotherapy at the Christie Hospital Manchester. Patients were treated with doses of 50-55 Gy in 16 fractions over 3 weeks. Data were collected retrospectively for local and regional control, survival, and morbidity. Results: Overall local control, after surgical salvage in 17 cases, was 79% (T1-92%, T2-81%, T3-67%, T4-73%). Overall regional lymph node control, after surgical salvage in 13 cases, was 84% (T1-91%, T2-88%, T3-81%, T4-72%). Five-year crude survival was 50%, but after correcting for intercurrent deaths was 70% (T1-83%, T2-78%, T3-53%, T4-61%). Serious morbidity requiring surgery was seen in 7 cases (2.1%) and was related to prescribed dose (50 Gy-0%, 52.5 Gy-1.3%, 55 Gy-3.4%). Discussion: Our results confirm that treating a modest size, fixed field to a high biologically effective dose is highly effective. It enables preservation of the larynx in most cases, with acceptable regional control and no loss of survival compared to whole neck radiotherapy regimes

    To investigate the diagnostic value of contrast-enhanced computed tomography (CT) for the prediction of deep neck abscesses in different deep neck spaces and to evaluate the false-positive results. We retrospectively analysed the clinical charts, CT examinations, surgical findings, bacteriology, pathological examinations and complications of hospitalised patients with a diagnosis of deep neck abscess from 2004 to 2010. The positive predictive values (PPV) for the prediction of abscesses by CT scan in different deep neck spaces were calculated individually on the basis of surgical findings. A total of 162 patients were included in this study. All patients received both intravenous antibiotics and surgical drainage. The parapharyngeal space was the most commonly involved space. The overall PPV for the prediction of deep neck abscess with contrast-enhanced CT was 79.6%. The PPV was 91.3% when more than one deep neck space was involved but only 50.0% in patients with isolated retropharyngeal abscesses. In the false-positive group, cellulitis was the most common final result, followed by cystic degeneration of cervical metastases. Five specimens taken intra-operatively revealed malignancy and four of these were not infected. There are some limitations affecting the differentiation of abscesses and cellulitis, particularly in the retropharyngeal space. A central necrotic cervical metastatic lymph node may sometimes also mimic a simple pyogenic deep neck abscess on both clinical pictures and CT images. Routine biopsy of the tissue must be performed during surgical drainage.

    Surgery and/or radiotherapy have been the standard therapies for locally advanced squamous cell carcinoma of the head and neck region. Despite major improvement in these therapeutic techniques, the control rate in cases of advanced cancer remains poor. More recently, induction chemotherapy as initial treatment has been used in previously untreated squamous cell carcinoma of the head and neck. For the last 6 years at the Boston Veterans Administration (V.A.) Medical Center, initial induction chemotherapy followed by surgery and/or radiotherapy has been employed in the treatment of advanced head and neck cancer. The use of chemotherapy and radiotherapy has allowed the authors to monitor and correlate sequential response patterns produced by each modality of treatment. The authors have observed that responders to chemotherapy can be predicted to have further response to subsequent radiotherapy

    Full Text Available Introduction: Acquired immunodeficiency syndrome (AIDS is a worldwide infection. Because of the vast array of manifestations of AIDS and its many atypical presentations, it is becoming increasingly challenging for clinicians to accurately diagnose new lesions. Materials and Methods: In a descriptive cross-sectional study conducted from 2007 to 2010, 50 patients with a proven human immunodeficiency virus (HIV infection were evaluated. Based on the findings of a physical examination and paraclinic tests, HIV signs and symptoms were recorded.   Results: The mean (range age of the patients was 35.45 ±5.24 (5–55 years. Forty-two (84% cases were male and eight were female. The mean duration of carrying the virus was 4.51 ±1.03 years. Oral manifestations were the most common (94%, followed by rhinologic (88%, otologic (66%, and finally neck (44% manifestations.   Conclusion:  Head and neck presentations are very common in HIV patients; therefore otolaryngologists, as the first physicians who may encounter such patients, should be aware of this condition.

    The prevalence of hypothyroidism in SLE patients varies considerably and early reports were mainly based on small cohorts. To investigate the association between SLE and hypothyroidism. Patients with SLE were compared with age and sex-matched controls regarding the proportion of hypothyroidism in a case-control study. Chi-square and t-tests were used for univariate analysis and a logistic regression model was used for multivariate analysis. The study was performed utilizing the medical database of Clalit Health Services. The study included 5018 patients with SLE and 25,090 age and sex-matched controls. The proportion of hypothyroidism in patients with SLE was increased compared with the prevalence in controls (15.58% and 5.75%, respectively, Phypothyroidism (odds ratio 2.644, 95% confidence interval 2.405-2.908). Patients with SLE have a greater proportion of hypothyroidism than matched controls. Therefore, physicians treating patients with SLE should be aware of the possibility of thyroid dysfunction.

    2013-01-01

    Full text: Introduction: Advanced neoplastic processes in the neck can cause acute life-threatening bleeding. Source of the bleeding can be vessels from a tumor mass or invasion of the main cervical arterial vessels. Poor general condition of the patients and accompanying complications create additional difficulties in getting these situations under control. What you will learn: Endovascular embolization of acute bleeding from advanced cervical neoplasms requires detailed knowledge of anatomical structures in this area and precision equipment with the possibility of super selective catheterization of small caliber vessels. The presentation discusses the various embolization materials and possibilities for their application in the neck. The experience of 5 embolization sessions in 4 patients is presented. An important point is discussion of the possible complications and how to avoid them. Discussion: Acute bleeding from large tumor formation is often a real risk to the life of the patient. Getting these conditions under control usually postpones the poor prognosis of the main disease. Postembolization syndrome and postembolization tissue necrosis define the basic cares in the early and late period after such a procedure. Conclusion: Acute bleeding from advanced neoplastic processes in the neck offers a real challenge. For their successful mastery it is required certain technical skills, unconventional solutions and a wide range of materials for embolization. A multidisciplinary approach is required to view the specific care these patients need and the possible complications

    treated by physical therapists. The exact mechanism of neck pain is rarely revealed by clinical examination and the treatment has varied from passive rest to active treatments. Active treatments have often been divided into either training of the painful area or the surrounding musculature avoiding direct...... training of the painful area. Our study investigates the effect of the latter approach. METHODS/DESIGN: A randomized controlled trial of 10 weeks duration is currently being conducted. Employed office workers with severe neck-shoulder pain are randomized to 3 × 20 min shoulder function training...... with training supervision or to a reference group receiving advice to stay physically active. Shoulder function training primarily focuses on the serratus anterior and lower trapezius muscle with only minimal activation the upper trapezius.An announcement was sent to the administrative section of the university...

    2009-01-01

    Thirty-one cases of hypopharyngeal cancer with neck dissection preceding radiation and 16 cases of hypopharyngeal cancer with neck dissection for locoregional recurrences after radiation were reviewed in order to make comparative evaluations of difficulty in surgical operation, postoperative complications, laryngeal preservation rate, and cause specific 5-year survival rate retrospectively. And quality of life (QOL) after neck dissection was additionally evaluated through the questionnaire. Since neck dissection preceding radiation for hypopharyngeal cancer may be superior to neck dissection for radiation failure, with easy surgical approach an non-lymphoid tissue preservation, that modality can be a reasonable choice of treatment for patients with nodal lesions, which are probably difficult to treat with radiation alone. Even though further investigation on QOL questionnaire is necessary, this modality can make a contribution to the neck and shoulder condition after neck dissection. (author)

Conclusion: Impedance-controlled microcurrent therapy shows promise for remediation of range-of-motion limitations arising as late effects of radiotherapy for head-and-neck cancer. Additional studies are needed to validate these preliminary results and to optimize the microcurrent treatment protocol, particularly with respect to treatment schedules and combining microcurrent therapy with physical and/or drug therapy

    Most studies find strong evidence that motorcycle helmets protect against injury, but a small number of controversial studies have reported a positive association between helmet use and neck injury. The most commonly cited paper is that of Goldstein (1986). Goldstein obtained and reanalyzed data from the Hurt Study, a prospective, on-scene investigation of 900 motorcycle collisions in the city of Los Angeles. The Goldstein results have been adopted by the anti-helmet community to justify resistance to compulsory motorcycle helmet use on the grounds that helmets may cause neck injuries due to their mass. In the current study, we replicated Goldstein's models to understand how he obtained his unexpected results, and we then applied modern statistical methods to estimate the association of motorcycle helmet use with head injury, fatal injury, and neck injury among collision-involved motorcyclists. We found Goldstein's analysis to be critically flawed due to improper data imputation, modeling of extremely sparse data, and misinterpretation of model coefficients. Our new analysis showed that motorcycle helmets were associated with markedly lower risk of head injury (RR 0.40, 95% CI 0.31-0.52) and fatal injury (RR 0.44, 95% CI 0.26-0.74) and with moderately lower but statistically significant risk of neck injury (RR 0.63, 95% CI 0.40-0.99), after controlling for multiple potential confounders.

    Full Text Available 【Abstract】Femoral neck stress fractures (FNSFs are rare, constituting only 5% of all stress fractures in young adults. These fractures are usually seen in athletes, military recruits and patients with underlying metabolic diseases. The treatment of FNSFs is still controversial because of the inherent complications associated with the treatment procedure. We came across 4 cases of bilateral FNSFs in non-athletic individuals who were manual labourers with-out underlying bony disorders. Two patients with FNSFs and coxa vara deformity on both sides were managed by subtrochanteric valgus osteotomy and dynamic hip screw fixation. One of the remaining two patients was treated by cannulated cancellous screw fixation on one side and sub-trochanteric valgus osteotomy on the other side. The fourth patient received subtrochanteric valgus osteotomy on one side and bipolar hemiarthroplasty on the other side after failed cannulated screw fixation. All the fractures healed without any complications. No evidence of avascular ne-crosis or arthritis was noted in our series. Subtrochanteric valgus osteotomy restores normal neck-shaft angle in pa-tients suffering from FNSFs combined with coxa vara deformity. Moreover, it helps to bring the forces acting around the hip to normal biomechanical levels, leading to fracture union and better results. Replacement arthroplasty is recommended to patients who fail to achieve bony union after fixation. Key words: Fractures, stress; Femoral neck fractures; Coxa vara; Osteotomy

  16. Talar Neck Fracture after United Tibiotalar Fusion

    Full Text Available Tibiotalar arthrodesis is a well-established treatment for tibiotalar arthritis, for example, in younger high demand patients. Talar neck fractures are less common though well-recognised sequelae of foot ankle trauma. Here we present the clinical case of a 69-year-old male who presented to our institution with a nonunion of a talar neck fracture, having undergone a left tibiotalar fusion 24 years previously. To the authors’ knowledge, this injury has only been described once previously in the literature. However, the original case described a fracture sustained in the very early postoperative period following tibiotalar fusion, postulated to be secondary to postimmobilisation osteopaenia or stress risers from metalwork. The aetiology in this case is likely due to axial compression transmitted to the talar neck via the calcaneus. The predisposing factors for nonunion are discussed, highlighting the importance of vigilance for this injury in any patient with concomitant tibiotalar fusion and foot trauma. The management of this patient is discussed.

    Case-control studies show a possible relationship between oral bacteria and head and neck squamous cell cancer (HNSCC). Prospective studies are needed to examine the temporal relationship between oral microbiome and subsequent risk of HNSCC. To prospectively examine associations between the oral microbiome and incident HNSCC. This nested case-control study was carried out in 2 prospective cohort studies: the American Cancer Society Cancer Prevention Study II Nutrition Cohort (CPS-II) and the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO). Among 122 004 participants, 129 incident patient cases of HNSCC were identified during an average 3.9 years of follow-up. Two controls per patient case (n = 254) were selected through incidence density sampling, matched on age, sex, race/ethnicity, and time since mouthwash collection. All participants provided mouthwash samples and were cancer-free at baseline. Oral microbiome composition and specific bacterial abundances were determined through bacterial 16S rRNA gene sequencing. Overall oral microbiome composition and specific taxa abundances were compared for the case group and the control group, using PERMANOVA and negative binomial generalized linear models, respectively, controlling for age, sex, race, cohort, smoking, alcohol, and oral human papillomavirus-16 status. Taxa with a 2-sided false discovery rate (FDR)-adjusted P-value (q-value) <.10 were considered significant. Incident HNSCC. The study included 58 patient cases from CPS-II (mean [SD] age, 71.0 [6.4] years; 16 [27.6%] women) and 71 patient cases from PLCO (mean [SD] age, 62.7 [4.8] years; 13 [18.3%] women). Two controls per patient case (n = 254) were selected through incidence density sampling, matched on age, sex, race/ethnicity, and time since mouthwash collection. Head and neck squamous cell cancer cases and controls were similar with respect to age, sex, and race. Patients in the case group were more often current tobacco

    Full Text Available BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs have been associated with upper gastrointestinal (GI bleeding. Given their worldwide use, even small risks account for a large number of cases. This study has been conducted with carefully collected information to further investigate the relationship between SSRIs and upper GI bleeding. METHODS: We conducted a case-control study in hospitals in Spain and in Italy. Cases were patients aged ≥18 years with a primary diagnosis of acute upper GI bleeding diagnosed by endoscopy; three controls were matched by sex, age, date of admission (within 3 months and hospital among patients who were admitted for elective surgery for non-painful disorders. Exposures to SSRIs, other antidepressants and other drugs were defined as any use of these drugs in the 7 days before the day on which upper gastrointestinal bleeding started (index day. RESULTS: 581 cases of upper GI bleeding and 1358 controls were considered eligible for the study; no differences in age or sex distribution were observed between cases and controls after matching. Overall, 4.0% of the cases and 3.3% of controls used an SSRI antidepressant in the week before the index day. No significant risk of upper GI bleeding was encountered for SSRI antidepressants (adjusted odds ratio, 1.06, 95% CI, 0.57-1.96 or for whichever other grouping of antidepressants. CONCLUSIONS: The results of this case-control study showed no significant increase in upper GI bleeding with SSRIs and provide good evidence that the magnitude of any increase in risk is not greater than 2.

    Adult patients with hypothalamic-pituitary disorders have compromised quality of life (QoL). Whether this is due to their endocrine consequences (hypopituitarism), their underlying hypothalamic-pituitary disorder or both is still under debate. The aim of this trial was to measure quality of life (QoL) in long-term cancer survivors who have received a radiation dose to the basal part of the brain and the pituitary. Consecutive patients (n=101) treated for oropharyngeal or epipharyngeal cancer with radiotherapy followed free of cancer for a period of 4 to10 years were identified. Fifteen patients (median age 56 years) with no concomitant illness and no hypopituitarism after careful endocrine evaluation were included in a case-control study with matched healthy controls. Doses to the hypothalamic-pituitary region were calculated. QoL was assessed using the Symptom check list (SCL)-90, Nottingham Health Profile (NHP), and Psychological Well Being (PGWB) questionnaires. Level of physical activity was assessed using the Baecke questionnaire. The median accumulated dose was 1.9 Gy (1.5-2.2 Gy) to the hypothalamus and 2.4 Gy (1.8-3.3 Gy) to the pituitary gland in patients with oropharyngeal cancer and 6.0-9.3 Gy and 33.5-46.1 Gy, respectively in patients with epipharyngeal cancer (n=2). The patients showed significantly more anxiety and depressiveness, and lower vitality, than their matched controls. In a group of long time survivors of head and neck cancer who hade received a low radiation dose to the hypothalamic-pituitary region and who had no endocrine consequences of disease or its treatment QoL was compromised as compared with well matched healthy controls.

    Full Text Available BACKGROUND A multitude of lesions occur in the neck and patients come to hospital on account of morbidity associated with these lesions. Therefore a histopathological study of the spectrum of neck lesions was undertaken. MATERIALS AND METHODS All histologically diagnosed lesions of the neck from January 2014 to December 2015 were noted. Details of gender, age, location and diagnosis were recorded. The lesions were classified based on anatomic location, gross and histological features and clinically. Clinically, lesions were classified as congenital, inflammatory/infective and neoplastic. Incidence of age, gender and location of different lesions was calculated using percentage, and median. The findings were compared with other studies. RESULTS A total of 140 neck lesions were included in the current study. Neck lesions were predominant in females with 94 cases. The median age group involved was the 21-30 group. Anterior neck lesions were more common. Anterior midline lesions were 74 and mostly thyroid and thyroglossal duct origin. Lesions of the lymph node were greater in the posterior triangle. 122 lesions were solid and 18 were cystic. Histologically, there were 64 thyroid gland lesions, 40 lymph node lesions, 13 soft tissue tumours, 8 salivary lesions, 10 thyroglossal cysts and 5 skin/adnexal lesions. Clinically, congenital/developmental lesions were 11, inflammatory/infective lesions were 68 and neoplastic lesions were 61. Of the neoplastic lesions, 17 were malignant. CONCLUSION Non-neoplastic lesions of the neck were common in our study in accordance with findings in other studies. The most common malignancy was Papillary carcinoma of thyroid.

    The efficacy of elective neck irradiation (ENI) for patients with N0 carcinoma of the maxillary sinus has been controversial. The purpose of our study was to investigate the incidence of late neck recurrence and the mortality rate from regional disease in patients with N0 maxillary sinus cancer after superselective cisplatin infusion and concomitant radiotherapy (RADPLAT) without ENI. We retrospectively analyzed 48 patients with N0 maxillary sinus cancer who underwent RADPLAT. Chemotherapy consisted of 100-120 mg/m(2) superselective intra-arterial cisplatin administered at a median rate of four times weekly. Concurrent radiation therapy was administered at a median dose of 65 Gy without ENI. Late neck recurrence was observed in 8.3% (4/48). Three patients underwent salvage neck dissection and survived without any evidence of disease. The remaining patient did not undergo neck dissection due to coexistence with distant metastasis, and he died of regional disease. The mortality rate from regional disease was calculated to be 2% (1/48). The incidence of late neck recurrence was not frequent, and the mortality rate from regional disease was low. Salvage neck dissection was considered to be feasible for patients with late neck recurrence. When definitive radiotherapy and concomitant chemotherapy are applied, it is considered that ENI is not required for cases of N0 maxillary sinus cancer.

    Falls are a serious health problem for aged people, causing social and economic burden. Despite being an important determinant of balance, the positioning of the center of mass (COM) has not been evaluated as a risk factor for falls. This study examined the association between the percentage height of COM (%COM) and the risk of falls in the elderly. Healthy women aged 60 years and older were consecutively selected in a case-control study. Forty-eight individuals classified as "fallers" (having suffered two or more falls in the previous year) were the cases while 48 age and weight-matched women with one fall or no falls in the previous year were the controls ("non-fallers"). Body composition and bone mineral density (BMD) by DXA, 30-second chair stand test, abdominal circumference, Berg's balance scale and %COM using the reaction board method were evaluated in all participants. Body composition parameters were not significantly different between groups. Spine and hip BMD tended to be lower in the fallers, but the difference was significant only at the femoral neck (0.80±0.10g/cm(2) versus 0.87±0.76g/cm(2); pfalls. Further work is needed in order to determine the value of board reaction measurements in a clinical setting to identify patients at high risk. Copyright © 2011 Elsevier B.V. All rights reserved.

    Purpose: To compare quality of life (QOL) and xerostomia between head-and-neck cancer patients who received standard radiotherapy (RT) and patients matched by factors known to affect QOL who received intensity-modulated RT (IMRT). Methods and Materials: This was a prospective, longitudinal study of patients with head-and-neck cancer requiring bilateral neck irradiation who received IMRT at the University of Michigan and patients who received standard RT at affiliated clinics. Each patient received a validated head-and-neck cancer-related QOL questionnaire (HNQOL) consisting of four multi-item domains-Eating, Communication, Pain, and Emotion-and a validated patient-reported xerostomia questionnaire (XQ). In both questionnaires, the answers were scored 0-100, with higher scores denoting worse QOL or xerostomia. The questionnaires were given before therapy and at 1, 3, 6, 12, 18, and 24 months after the completion of therapy. Each standard RT patient was matched with several IMRT patients according to tumor site, stage, RT status (postoperative or definitive), and age. A linear mixed-effects model was fit to compare outcomes between the two treatment groups and to model trends over time. To account for matching, the differences in scores between the matched sets of patients were fit as a random intercept. Also, matching was taken into account in the model by using the standard error of the within-paired-groups differences. Results: Between 1997 and 2002, 10 patients who had received standard RT and answered the XQ and HNQOL through at least 1 year were included in the study. Each of these patients was matched with a subgroup of 2-5 patients (median, 3) who had received IMRT, had similar patient and tumor characteristics, and answered the same questionnaires. A total of 30 patients were included in the IMRT group. During the initial months after therapy, the XQ and HNQOL summary scores worsened significantly in both groups compared with the pretherapy scores. Starting

    Neck pain is a widespread complaint. People experiencing neck pain often present an altered timing in contraction of cervical muscles. This altered afferent information elicits the cervico-ocular reflex (COR), which stabilizes the eye in response to trunk-to-head movements. The vestibulo-ocular reflex (VOR) elicited by the vestibulum is thought to be unaffected by afferent information from the cervical spine. The aim of the study was to measure the COR and VOR in people with nonspecific neck pain. This study utilized a cross-sectional design in accordance with the STROBE statement. An infrared eye-tracking device was used to record the COR and the VOR while the participant was sitting on a rotating chair in darkness. Eye velocity was calculated by taking the derivative of the horizontal eye position. Parametric statistics were performed. The mean COR gain in the control group (n=30) was 0.26 (SD=0.15) compared with 0.38 (SD=0.16) in the nonspecific neck pain group (n=37). Analyses of covariance were performed to analyze differences in COR and VOR gains, with age and sex as covariates. Analyses of covariance showed a significantly increased COR in participants with neck pain. The VOR between the control group, with a mean VOR of 0.67 (SD=0.17), and the nonspecific neck pain group, with a mean VOR of 0.66 (SD=0.22), was not significantly different. Measuring eye movements while the participant is sitting on a rotating chair in complete darkness is technically complicated. This study suggests that people with nonspecific neck pain have an increased COR. The COR is an objective, nonvoluntary eye reflex and an unaltered VOR. This study shows that an increased COR is not restricted to patients with traumatic neck pain. © 2016 American Physical Therapy Association.

    Background and purpose: In this prospective study, the effect of a second course of primary radiotherapy on locoregional control, survival and toxicity was investigated, in patients who underwent a second course of high dose irradiation for second primary or locoregional recurrent squamous cell head and neck carcinoma (HNSCC) in a previously irradiated area. Patients and methods: A total of 34 patients with second primary (n=26) or locoregional recurrent (n=8) tumours were treated with a second course of high dose radiotherapy. Patients were selected for re-irradiation in case of inoperable and/or unresectable tumours. In most cases, the target volume for re-irradiation was confined to the gross tumour volume (GTV). No elective radiotherapy was applied in the former high-dose area. A total dose of 46 Gy was applied to elective areas with a boost up to 60 Gy with conventional fractionation. The median follow-up period was 32 months. Results: The locoregional control rate after 2 years was 27%. The 3-year overall survival was 22%. The most frequently reported acute side-effect was acute mucositis resulting in swallowing complaints. Pharyngeal and oesophageal late morbidity was also the most important late side-effect. In general, acute and late radiation-induced morbidity remained within acceptable limits. Conclusions: In conclusion, primary re-irradiation appears to be feasible in terms of acute and late radiation-induced toxicity. To improve outcome in terms locoregional control and survival, future studies should be focussed on optimising radiation schedules and the addition of concomitant chemotherapy

    The research aimed to investigate the effectiveness of cupping therapy (CT) in changes on skin surface temperature (SST) for relieving chronic neck and shoulder pain (NSP) among community residents. A single-blind experimental design constituted of sixty subjects with self-perceived NSP. The subjects were randomly allocated to two groups. The cupping group received CT at SI 15, GB 21, and LI 15 acupuncture points, and the control group received no intervention. Pain was assessed using the SST, visual analog scale (VAS), and blood pressure (BP). The main results were SST of GB 21 acupuncture point raised from 30.6°C to 32.7°C and from 30.7°C to 30.6°C in the control group. Neck pain intensity (NPI) severity scores were reduced from 9.7 to 3.6 in the cupping group and from 9.7 to 9.5 in the control group. The SST and NPI differences between the groups were statistically significant (P < 0.001). One treatment of CT is shown to increase SST. In conjunction with the physiological effect the subjective experience of NSP is reduced in intensity. Further studies are required to improve the understanding and potential long-term effects of CT.

    Full Text Available Ovarian cancer is second prevalent cancer among gynecologic malignancies and the most common type of ovarian cancer is epithelial form (85-90 percent. To detect the risk factors for the epithelial ovarian cancer, a case-control study was conducted in Valieasr hospital in 1988. In this study, 118 cases with epithelial ovarian cancer (according histological records and 240 controls without any gynecological cancer in gynecologic clinic had been interviewed. For data analysis, T-test, Chi2 test and logistic regression have been used at a =0.05 as level of significance. The mean age in cases was 50±13 and in controls was 49.9±12 years, without significant different. The mean number of pregnancies and parity in cases was less than controls, significantly (P<0.03. The mean months of breast feeding in cases was less than controls (54.9±71.2 versus 82.4±62.7 (P<0.001. The cases had a lower mean age of menarch than controls (P=0.03. 58 percent of cases and 21.3 percent of controls hadn't used any contraception methods (P=0.00001. The mean years of contraception was significantly less in cases versus controls (P<0.001. The odds ratio for epithelial ovarian cancer was 0.24 (95 percent CI: 0.13-0.48 in OCP users, 0.47 (95 percent CI: 0.005-0.43 in TL method, and was 0.41 (95 percent CI: 0.22-0.76 in other contraception methods, relative to women who hadn't used any contraception methods. This study reveals that epithelial ovarian cancer risk increases significantly with earlier menarch, decreasing number of pregnancy, deliveries duration of breast feeding and use of contraception methods. Use of contraception pill and tubal ligation method decreases risk of epithelial ovarian cancer.

    Skin puckering is a sign that is well associated with certain fractures such as supracondylar humeral fractures in children. To our knowledge, there has been only one clinical report of skin puckering associated with fractured neck of humerus of an adult. This is a second such case of fractured proximal humerus in an adult presenting with skin puckering and the first from the Republic of Ireland. Skin puckering is suggestive of soft tissue interposition and may be an important clinical sign indicating the need for internal fixation.

    Twenty-four cases of advanced T4 cancers of the head and neck were treated using a twice-a-day treatment fractionation delivering a 1,200 rad weekly tumor dose and 7,000 rad total tumor dose in 5 1 / 2 to 6 weeks. Acute normal mucosal reactions and skin reactions were plotted weekly and corresponded to reactions observed when delivering 1,000 rad per week in five treatment sessions. Chronic problems have been limited to severe neck fibrosis appearing in three of five patients who underwent a planned neck dissection 6 weeks after the completion of radiotherapy. Local control was observed in 14 of 23 patients (61%) and regional control in 22 of 23 patients

    In clinical research of rare diseases, where small patient numbers and disease heterogeneity limit study design options, registries are a valuable resource for demographic and outcome information. However, in contrast to prospective, randomized clinical trials, the observational design of registries is prone to introduce selection bias and negatively impact the validity of data analyses. The objective of the study was to demonstrate the utility of case-control matching and the risk-set method in order to control bias in data from a rare disease registry. Data from the International Collaborative Gaucher Group (ICGG) Gaucher Registry were used as an example. A case-control matching analysis using the risk-set method was conducted to identify two groups of patients with type 1 Gaucher disease in the ICGG Gaucher Registry: patients with avascular osteonecrosis (AVN) and those without AVN. The frequency distributions of gender, decade of birth, treatment status, and splenectomy status were presented for cases and controls before and after matching. Odds ratios (and 95% confidence intervals) were calculated for each variable before and after matching. The application of case-control matching methodology results in cohorts of cases (i.e., patients with AVN) and controls (i.e., patients without AVN) who have comparable distributions for four common parameters used in subject selection: gender, year of birth (age), treatment status, and splenectomy status. Matching resulted in odds ratios of approximately 1.00, indicating no bias. We demonstrated bias in case-control selection in subjects from a prototype rare disease registry and used case-control matching to minimize this bias. Therefore, this approach appears useful to study cohorts of heterogeneous patients in rare disease registries.

    The records of 54 consecutive patients who were irradiated for metastatic disease in the neck from an unknown primary tumor were reviewed. The overall survival results are comparable to those of other reported series. Patients with high or posterior cervical lymph node involvement were irradiated with fields including the nasopharynx and oropharynx. Patients with high neck nodes had a better survival rate than those with low neck nodes. The size of the neck tumors and the local control after treatment also have prognostic significance. (Auth.)

    There are a number of different dwell positions and time optimisation options available in the Oncentra® Brachy (Elekta Brachytherapy Solutions, Veenendaal, The Netherlands) brachytherapy treatment planning system. The purpose of this case study was to compare graphical (GRO) and inverse planning by simulated annealing (IPSA) optimisation techniques for interstitial head and neck (HN) and prostate plans considering dosimetry, modelled radiobiology outcome and planning time. Four retrospective brachytherapy patients were chosen for this study, two recurrent HN and two prostatic boosts. Manual GRO and IPSA plans were generated for each patient. Plans were compared using dose–volume histograms (DVH) and dose coverage metrics including; conformity index (CI), homogeneity index (HI) and conformity number (CN). Logit and relative seriality models were used to calculate tumour control probability (TCP) and normal tissue complication probability (NTCP). Approximate planning time was also recorded. There was no significant difference between GRO and IPSA in terms of dose metrics with mean CI of 1.30 and 1.57 (P > 0.05) respectively. IPSA achieved an average HN TCP of 0.32 versus 0.12 for GRO while for prostate there was no significant difference. Mean GRO planning times were greater than 75 min while average IPSA planning times were less than 10 min. Planning times for IPSA were greatly reduced compared to GRO and plans were dosimetrically similar. For this reason, IPSA makes for a useful planning tool in HN and prostate brachytherapy

    To evaluate the role of selective neck dissection in the treatment of recurrent branchial anomalies. The clinical data of 18 patients with recurrent branchial anomalies were retrospectively analyzed. In accordance with the embryologic and anatomic features of branchial anomalies, different types of selective neck dissection were applied. With dissection and protection of important vessels, nerves and other structures, enbloc resection principles were applied to extirpate branchial lesions, scarrings and inflammatory granuloma during the operation. Of all 18 patients, 16 cases were healed with primary healing, 2 cases with local incision infection were healed after dressing changes. A temporary facial nerve paralysis occurred in 1 case with recurrent first branchial cleft fistula postoperatively, and completely recovered 2 months after operation. A postoperative temporary vocal cord paralysis occurred in 1 case with recurrent fourth branchial cleft fistula, and totally recuperated 1 month after operation. No recurrences were found in all 18 cases with a follow-up period of 12-78 months (average 35 months). Selective neck dissection is a safe and effective surgical procedure for the radical treatment of recurrent branchial anomalies.

    Genetic association is often determined in case-control studies by the differential distribution of alleles or genotypes. Recent work has demonstrated that association can also be assessed by deviations from the expected distributions of alleles or genotypes. Specifically, multiple methods motivated by the principles of Hardy-Weinberg equilibrium (HWE) have been developed. However, these methods do not take into account many of the assumptions of HWE. Therefore, we have developed a prevalence-based association test (PRAT) as an alternative method for detecting association in case-control studies. This method, also motivated by the principles of HWE, uses an estimated population allele frequency to generate expected genotype frequencies instead of using the case and control frequencies separately. Our method often has greater power, under a wide variety of genetic models, to detect association than genotypic, allelic or Cochran-Armitage trend association tests. Therefore, we propose PRAT as a powerful alternative method of testing for association.

    We performed this study to assess the value of CT in the differential diagnosis of palpable neck masses in children. We retrospectively reviewed the CT scans of the palpable neck masses in 30 children. The masses were proved histopathologically and classified into cystic, solid, and inflammatory mass and their CT findings were analyzed. Twelve cases were cystic masses, 4 were solid masses, and 14 were inflammatory lesions. Cystic masses included cystic lymphangiomas (n=6), branchial cleft cysts (n=3), thyroglossal duct cysts (n=2), and ranula (n=1). Cystic lymphangiomas showed insinuating appearances into adjacent structures and 4 cases occurred in the posterior cervical space. All branchial cleft cysts were round cystic masses with smooth wall and displaced the submandibular gland anteriorly and the sternocleidomastoid muscle posteriorly. Two thyroglossal duct cysts occurred centrally adjacent to the hyoid bone and 1 ranula in the submental area. Solid masses were juvenile hemangioma, pleomorphic adenoma in submandibular gland, neurilemmoma, and fibromatosis colli. Juvenile hemangioma showed well-enhancing mass with indistinct margin and the other solid masses had well-defined margin with their characteristic location. Inflammatory lesions were abscess (n=4), deep neck infections with lymphadenopathy (n=4), submandibular gland inflammation (n=3), and tuberculous lymphadenitis (n=3) and they showed strand-like enhancement in adjacent subcutaneous tissues. Tuberculous lymphadenitis had multiple lymph node enlargement with internal low attenuation areas and showed less surrounding strand-like enhancement than suppurative lymphadenopathies. Most neck masses in infants and children were of congenital or inflammatory origin. CT is useful for the evaluation of the child presenting with a neck mass, because it can differentiate various forms of neck masses and is able to reveal the relationship of the masses to the adjacent structures with their characteristic location

    Full Text Available Purpose. One of the common side effects experienced by head and neck cancer patients on chemoradiotherapy is mucositis. Severe mucositis may be controllable by limiting cancer therapy, but it has resulted in decreasing the completion rate of chemoradiotherapy. The efficacy of royal jelly (RJ as prophylaxis against chemoradiotherapy-induced mucositis was evaluated through clinical scoring of oral and pharyngeal mucositis. Methods. In this randomized, single-blind (physician-blind, clinical trial, 13 patients with head and neck cancer requiring chemoradiation were randomly assigned to two groups. Seven patients assigned to the study group received RJ, and 6 patients were assigned to the control group. RJ group patients took RJ three times per day during treatment. The patients in both groups were evaluated twice a week for the development of mucositis using Common Terminology Criteria for Adverse Events version 3.0. Results. A significant reduction in mucositis was seen among RJ-treated patients compared with controls (P<0.001. Conclusion. This study demonstrated that prophylactic use of RJ was effective in reducing mucositis induced by chemoradiotherapy in head and neck cancer patients. However, further studies are needed because of the small sample size and the absence of double blinding.

    The Neck Rupture Model is a model that explains the scission process which has smallest radius in liquid drop at certain position. Old fashion of rupture position is determined randomly so that has been called as Random Neck Rupture Model (RNRM). The neck curve polynomials have been employed in the Neck Rupture Model for calculation the fission yield of neutron induced fission reaction of 280 X 90 with changing of order of polynomials as well as temperature. The neck curve polynomials approximation shows the important effects in shaping of fission yield curve.

    Many pneumonia etiology case-control studies exclude controls with respiratory illness from enrollment or analyses. Herein we argue that selecting controls regardless of respiratory symptoms provides the least biased estimates of pneumonia etiology. We review 3 reasons investigators may choose to exclude controls with respiratory symptoms in light of epidemiologic principles of control selection and present data from the Pneumonia Etiology Research for Child Health (PERCH) study where relevant to assess their validity. We conclude that exclusion of controls with respiratory symptoms will result in biased estimates of etiology. Randomly selected community controls, with or without respiratory symptoms, as long as they do not meet the criteria for case-defining pneumonia, are most representative of the general population from which cases arose and the least subject to selection bias. © The Author 2017.

    Full Text Available Radiation arteritis following neck irradiation as a treatment for head and neck malignancy has been well documented. The long-term sequelae of radiation exposure of the carotid arteries may take years to manifest clinically, and extra-cranial carotid artery (ECCA stenosis is a well-recognised vascular complication. These carotid lesions should not be regarded as benign and should be treated in the same manner as standard carotid stenosis. Previous studies have noted increased cerebrovascular events such as stroke in this cohort of patients because of high-grade symptomatic carotid stenosis resulting in emboli.To evaluate the effect of radiation therapy on ECCA atherosclerosis progression.Online search for case-control studies and randomised clinical trials that reported on stenosis in extra-cranial carotid arteries in patients with neck malignancies who received radiation therapy (RT comparing them to patients with neck malignancies who did not receive RT.Eight studies were included in the final analysis with total of 1070 patients - 596 received RT compared to 474 in the control group. There was statistically significant difference in overall stenosis rate (Pooled risk ratio  =  4.38 [2.98, 6.45], P  =  0.00001 and severe stenosis (Pooled risk ratio  =  7.51 [2.78, 20.32], P <0.0001, both being higher in the RT group. Pooled analysis of the five studies that reported on mild stenosis also showed significant difference (Pooled risk ratio  =  2.74 [1.75, 4.30], 95% CI, P  =  0.0001.The incidence of severe ECCA stenosis is higher among patients who received RT for neck malignancies. Those patients should be closely monitored and screening programs should be considered in all patients who receive neck RT.

    A new temperature-controlled device has been used as a percutaneous radio frequency probe to treat lax submental and other facial areas. It has significant advantages over other esthetic devices as it provides the dual benefit of fat lipolysis and skin tightening. Our goal here is to present consensus recommendations for treating the aging neck. A panel of 11 expert physicians convened in Dallas, Texas, on October 15, 2016 to arrive at a consensus on the best current practice for submental skin tightening and contour improvement. Prior to the meeting, a comprehensive review of the literature was performed and a survey was sent to esthetic dermatologists and plastic surgeons who were queried about various aspects of neck rejuvenation. The literature search revealed 10 different technologies for neck rejuvenation evaluated in double-blind (n = 2) and single-blind (n = 1) clinical trials and other clinical evaluations (n = 21). The survey was sent via an email to 1248 individuals and was completed by 92 respondents. Review of the data and discussion by meeting attendees generated eight consensus recommendations. Subdermal monopolar radio frequency represents an effective means for disrupting fat volume and skin tightening of the face, neck, and jawline. For suitable patients, this treatment can be used to achieve significant esthetic improvements.

    Factors such as prolonged sitting at work or improper posture of head during work may have a great role in neck pain occurrence among office employees, particularly among those who work with computers. Although some studies claim a significant difference in head posture between patients and pain-free participants, in literature the forward head posture (FHP) has not always been associated with neck pain. Since head, cervical and thoracic postures and their relation with neck pain has not been studied in Iranian office employees, the purpose of this study was to investigate the relationship between some work-related and individual factors, such as poor posture, with neck pain in the office employees. It was a cross-sectional correlation study carried out to explore the relationship between neck pain and sagittal postures of cervical and thoracic spine among office employees in forward looking position and also in a working position. Forty-six subjects without neck pain and 55 with neck pain were examined using a photographic method. Thoracic and cervical postures were measured using the high thoracic (HT) and craniovertebral (CV) angles, respectively. High thoracic and CV angles were positively correlated with the presence of neck pain only in working position (p 0.05). Our findings have revealed that office employees had a defective posture while working and that the improper posture was more severe in the office employees who suffered from the neck pain.

    Objective: To study the CT perfusion features of various lymph nodes in the neck. Methods: Dynamic perfusion CT scanning was performed in 83 neck lymph nodes proved by pathology, including tuberculosis lymph nodes, lymphoma and metastatic lymph nodes. The shapes, blood flow modes, and perfusion parameters of these lymph nodes were compared among 3 groups. Statistical analysis of L/T and CT perfusion parameters was performed by one-way ANOVA and LSD test. Results: The values of MTT of tuberculosis lymph nodes, lymphoma and metastatic lymph nodes were (28.13±5.08), (31.08±5.82), and (11.24±5.31) s, respectively. The MTT of metastatic lymph nodes was statistically lower than that of tuberculosis lymph nodes and lymphoma (P -1 · 100 g -1 , respectively. The values of BV were (24.68±2.84), (25.30±3.16), and (25.15± 8.81) ml·100 g -1 respectively. The values of TTP were (40.90±8.85), (40.67±6.45), and (40.98±6.62) s, respectively. There were no significant differences in L/T, BF, BV and TTP among tuberculosis lymph nodes, lymphoma and metastatic lymph nodes (P>0.05). Conclusion: CT perfusion, especially combination functional imaging with perfusion images may be helpful in judging the nature of neck lymph nodes. (authors)

    2017-07-01

    Full Text Available A 65-year-old male got admitted with complaints of anterior neck swelling for the past 10 years. The swelling was insidious in onset and gradually progressive in size. Initially, the swelling was of size 2 x 3 cm, which gradually progressed to its present size of about 7 x 5 cm. The swelling was not associated with pain. There was no history of difficulty in swallowing, hoarseness of voice or difficulty in breathing. There was no history suggestive of hyperthyroidism or hypothyroidism. There was no history of neck irradiation in the past or during childhood. Patient had not taken any treatment for thyroid disease and neither does the patient give history of any surgical intervention in the past. There was no history of similar swellings in the past

    median follow up of 26 months (range, 12-57 months), no regional failure was identified. The negative predictive value of PET was 100% and positive predictive value was 43%. Conclusion: For patients who have no evidence of residual lymphadenopathy and a negative FDG PET scan 12 weeks after definitive radiation, neck dissection can be safely withheld. Even in cases in which small residual lymphadenopathy was observed, regional recurrences have not occurred when the post-RT PET scan was negative and neck dissection was withheld. For patients with large residual lymphadenopathy (greater than 2.0-3.0 cm in size) but a negative post-RT FDG PET, further studies with longer follow-up are necessary to determine the appropriateness of withholding neck dissection

    Many patients desire cosmetic improvement of neck laxity when consulting with a plastic surgeon about their face. Neck laxity and loss of the cervicomental angle can be due to multiple components of aging such as skin quality/elasticity, loss of platysma muscle tone, and submental fat accumulation. Traditionally, the procedure of choice for patients with an aging lower face and neck is a cervicofacial rhytidectomy. However, occasionally, a patient wishes to have no other facial surgery than an improvement of their excessive skin of the anterior, lateral, and/or posterior neck. In other instances, a patient may present with having had a face/neck-lifting procedure that left objectionable vertical/diagonal lines at the lateral neck. In both these instances, a surgeon should consider an isolated stork lift (ISL) procedure. An ISL procedure avoids and/or corrects problematic vertical/diagonal lateral neck folds by "walking" the excess skin flaps around the posterior inferior occipital hairline bilaterally, bringing the flaps together at the lateral and posterior neck, which sometimes involves a midline posterior dart excision of the dog ear. A patient presenting with excessive skin of the neck (anterior, lateral, and/or posterior) and/or residual vertical/diagonal skin folds is an excellent candidate for the ISL. The ISL procedure was performed on 273 patients over a 2-year period at The Morrow Institute. Patients were included if they had excessive skin of the anterior, lateral, and/or posterior neck and/or diagonal/vertical lateral bands and did not desire a full face-lifting procedure. Patients were excluded from this study if they would not accept having longer hair in order to cover the scar along the posterior inferior occipital hairline or a midline T-flap skin closure scar at the base of the posterior midline neck. Under a combination of local anesthesia and IV sedation, a postauricular face-lift incision was made that was extended in a circumoccipital fashion

    Objective: To evaluate imaging appearances of herniation pit of the femoral neck. Methods: We retrospectively analyzed the X-ray, CT and MRI findings of 9 patients with herniation pit of the femoral neck. All nine patients were male with the age ranging from 21 to 73 years. They had pain in the hip from two months to two years duration. Results: The bilateral hips were affected in six patients, the right hips in the other 3 patients. Of the nine patients, X-ray plain films (2 cases), CT scanning(6 cases), and MR scanning (5 cases ) were performed. The size of the lesions ranged from 0.5 cm x 0.6 cm to 1.0 cm x 1.5 cm, located in the anterosuperior portion of the femoral neck (n=7) or anteroinferior portion (n=2). X-ray plain films showed an osteolytic lesion surrounded by a sclerotic rim. CT scanning showed the lesion just below the cortex of the femoral neck surrounded by a rim of sclerosis or associated with a small cortical break in two patients. MR scanning showed low signal intensity in five patients on T 1 WI and high signal intensity surrounded by a rim of low signal intensity (n=3) or low signal intensity (n=2) on T 2 WI, and high signal intensity on fat suppression MR image. A small joint effusion was observed in two cases on T 2 WI. Conclusion: The CT and MRI findings of herniation pit of the femoral neck are characteristic, it is useful in defining the diagnosis of the herniation pit of the femoral neck. (authors)

    Population attributable risks (PARs) are useful tool to estimate the burden of risk factors in cancer incidence. Few studies estimated the PARs of oral cavity cancer to tobacco smoking alone, alcohol drinking alone and their joint consumption but none performed analysis stratified by subsite, gender or age. Among the suspected risk factors of oral cavity cancer, only PAR to a family history of head and neck cancer was reported in two studies. The purpose of this study was to estimate in France the PARs of oral cavity cancer to several recognized and suspected risk factors, overall and by subsite, gender and age. We analysed data from 689 oral cavity cancer cases and 3481 controls included in a population-based case-control study, the ICARE study. Unconditional logistic regression models were used to estimate odds ratios (ORs), PARs and 95% confidence intervals (95% CI). The PARs were 0.3% (95% CI -3.9%; +3.9%) for alcohol alone, 12.7% (6.9%-18.0%) for tobacco alone and 69.9% (64.4%-74.7%) for their joint consumption. PAR to combined alcohol and tobacco consumption was 74% (66.5%-79.9%) in men and 45.4% (32.7%-55.6%) in women. Among suspected risk factors, body mass index 2 years before the interview role of combined tobacco and alcohol consumption in the oral cavity cancer burden in France and gives an indication of the proportion of cases attributable to other risk factors. Most of oral cavity cancers are attributable to concurrent smoking and drinking and would be potentially preventable through smoking or drinking cessation. If the majority of cases are explained by recognized or suspected risk factors in men, a substantial number of cancers in women are probably due to still unexplored factors that remain to be clarified by future studies.

  15. Inter-Vertebral Flexibility of the Ostrich Neck: Implications for Estimating Sauropod Neck Flexibility

    2013-01-01

    The flexibility and posture of the neck in sauropod dinosaurs has long been contentious. Improved constraints on sauropod neck function will have major implications for what we know of their foraging strategies, ecology and overall biology. Several hypotheses have been proposed, based primarily on osteological data, suggesting different degrees of neck flexibility. This study attempts to assess the effects of reconstructed soft tissues on sauropod neck flexibility through systematic removal o...

    1977-01-01

    This is a second report of a comprehensive case-control study of 11,000 individuals subjected to scalp x-irradiation in childhood between 1949 and 1960. Follow up was conducted through the following national records: Tumor, Registry, Central Population Registry, Mental Health Registry, Nationwide High School Aptitude Test, Police, Ministry of Welfare and the Army. In addition, a sample of the cases and of the controls was brought in for clinical examinations, psychological testing and computerized EEG. The mean dose delivered to the brain, as determined by dosimetric studies, was 140r and to the thyroid 6-9r. Specific topics to be presented and discussed are as follows: an increased risk of head and neck tumors and the presence of a dose response relationship. The implication of the marked increase in risk for thyroid tumors, in view of the low dose delivered to this organ. Radiation effect on brain function as evidenced by a lower educational achievement, a lower basic intelligence level, somewhat impaired mental ability, and an increased rate of admissions to mental hospitals among cases, as compared to each of the two control groups, as well as the presence of a hyperactivity pattern on EEG

    We undertook a study on a series of laryngeal sarcoidosis (LS), a very rare and often threatening localization to better specify laryngeal manifestations, sarcoidosis clinical expression and long-term follow-up. This was a retrospective case-control study. All LS patients from two French centers were included and compared to sarcoidosis patients without laryngeal localization with two controls for one patient. Twelve consecutive LS patients were recruited between 1993 and 2011. LS revealed sarcoidosis in eight cases (67%). The most common symptoms were hoarseness (77%), inspiratory dyspnea (38%) and dysphagia (38%). Epidemiological characterisics were not different. Extrapulmonary localizations were significantly more common in LS patients than in controls (92% vs. 54%, p=0.02), particularly lupus pernio (25% vs. 0%, p=0.03) and nasosinusal involvement (83% vs. 4%, p<0.01) while thoracic involvement was less frequent (58% vs 100%, p < 0.01). Treatment rates were higher in the LS group (92% vs. 58%, p=0.04), and treatment duration was longer (median: 81 vs. 13 months, p=0.04), with frequent long-term treatment (67%, N=8/12). Two patients underwent surgery. One patient needed temporary tracheostomy during the course of the disease; Remission rates were lower in LS patients (9% vs. 58% at 2 years p<0.01). Eventually, there was no death nor definitive tracheotomy. LS is a rare condition that is often associated to other loco-regional localizations. LS are often difficult to manage. Survival is good but may require a medico-surgical approach.

    The endovascular treatment of wide-neck bifurcation aneurysms can be challenging and often requires the use of adjunctive techniques and devices. We report our first experience of using a waffle-cone technique adapted to the Woven Endoluminal Bridge (WEB) device in a large-neck basilar tip aneurysm, suitable in cases where the use of Y stenting or other techniques is limited due to anatomic restrictions. The procedure was complete, and angiographic occlusion of the aneurysm was achieved 24 hours post treatment, as confirmed by digital subtraction angiography. No complications occurred. The case reported here was not suitable for Y stenting or deployment of the WEB device alone, due to the small caliber of both posterior cerebral arteries and their origin at the neck level. The main advantage of this technique is that both devices have a controlled detachment system and are fully independent. To our knowledge, this technique has not been reported previously and this modality of treatment has never been described in the literature. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available The paper reviews the literature related to the investigations of neck pain (cervicalgia in patients with headache (cephalalgia. Neck pain is second to lower back pain as a reason for considerable socioeconomic damage to society. The prevalence of cervicalgia in the population ranges from 5.9 to 38%; the annual incidence is 10.4–21.3%; 14.2 to 71% of people report to have neck pain at some time in their lifetime. Neck pain is concurrent with cephalalgia in 70% of cases. In patients with cervicalgia, the prevalence of headache is 20–40% higher than in those with musculoskeletal pain at another site. Neck pain is as a major risk factor for migraine and tension headache (TH. Neck pain in TH progresses with the increased intensity, frequency, and strength of headache. There is a direct relationship of the quality of life worsening associated withcervicalgia to the frequency of migraine attacks and the risk of its chronization. Neck pain is noted in cervicogenic headache belonging to secondary headaches. The identification of mixed headache in a patient with cervicalgia allows the prescription of a treatment option that may be effective in relieving both headache and neck pain. The paper discusses the causes and pathogenesis of cervicalgia in patients with headache, examination methods, and main approaches to drug and nondrug therapies in relation to the leading pathophysiological mechanism, as well as new possibilities for the effective and safe relief of pain syndrome in this category of patients. Nonsteroidal anti-inflammatory drugs, myorelaxants,and their combination are observed to be effective in treating patients with cervicalgia and cephalalgia.

    Full Text Available Abstract Background In clinical research of rare diseases, where small patient numbers and disease heterogeneity limit study design options, registries are a valuable resource for demographic and outcome information. However, in contrast to prospective, randomized clinical trials, the observational design of registries is prone to introduce selection bias and negatively impact the validity of data analyses. The objective of the study was to demonstrate the utility of case-control matching and the risk-set method in order to control bias in data from a rare disease registry. Data from the International Collaborative Gaucher Group (ICGG Gaucher Registry were used as an example. Methods A case-control matching analysis using the risk-set method was conducted to identify two groups of patients with type 1 Gaucher disease in the ICGG Gaucher Registry: patients with avascular osteonecrosis (AVN and those without AVN. The frequency distributions of gender, decade of birth, treatment status, and splenectomy status were presented for cases and controls before and after matching. Odds ratios (and 95% confidence intervals were calculated for each variable before and after matching. Results The application of case-control matching methodology results in cohorts of cases (i.e., patients with AVN and controls (i.e., patients without AVN who have comparable distributions for four common parameters used in subject selection: gender, year of birth (age, treatment status, and splenectomy status. Matching resulted in odds ratios of approximately 1.00, indicating no bias. Conclusions We demonstrated bias in case-control selection in subjects from a prototype rare disease registry and used case-control matching to minimize this bias. Therefore, this approach appears useful to study cohorts of heterogeneous patients in rare disease registries.

    Small cell carcinoma (SmCC) of the head and neck is an extremely rare neuroendocrine malignancy. In this study, we describe the incidence and determinants of survival of patients with SmCC of the head and neck between the years of 1973 and 2012 using the Surveillance, Epidemiology, and End Results database as differed by primary site. Retrospective, population-based cohort study. A total of 237 cases of SmCC of the head and neck were identified, which was divided into sinonasal primaries (n = 82) and all other head and neck primaries (n = 155). Clinicopathologic and epidemiologic variables were analyzed as predictors of overall survival (OS) and disease-specific survival (DSS) based on the Kaplan-Meier method. More than half of sinonasal primaries presented with Kadish stage C or D. On multivariate analysis, surgery was the only independent predictor of improved DSS (P = .008) for sinonasal primaries; in contrast, radiation therapy was a favorable prognosticator for OS (P = .007) and DSS (P = .043) in extrasinonasal sites. Comparison of survival between sinonasal primaries and all other sites demonstrated that sinonasal SmCC had uniformly better OS (P = .002) and DSS (P = .006). SmCC in the head and neck remains rare, and sinonasal primaries appear to have improved survival compared to other sites. Based on these results, optimal treatment for sinonasal SmCC appears to be surgical therapy, whereas radiation therapy is the preferred treatment for SmCC of other primary sites, particularly the larynx. 4.

    2010-07-01

    We describe a case of oncogenic osteomalacia in an adult male who presented with low back pain and bilateral hip pain. Extensive investigations had failed to find a cause. A plain pelvic radiograph showed Looser's zones in both femoral necks. MRI confirmed the presence of insufficiency fractures bilaterally in the femoral head and neck. Biochemical investigations confirmed osteomalacia which was unresponsive to treatment with vitamin D and calcium. A persistently low serum phosphate level suggested a diagnosis of hypophosphataemic osteomalacia. The level of fibroblast growth factor-23 was highly raised, indicating the cause as oncogenic osteomalacia. This was confirmed on positron-emission tomography, MRI and excision of a benign fibrous histiocytoma following a rapid recovery. The diagnosis of oncogenic osteomalacia may be delayed due to the non-specific presenting symptoms. Subchondral insufficiency fractures of the femoral head may be missed unless specifically looked for.

    Family physicians frequently encounter patients with neck mass. There are multiple causes that range from no clinical importance to malignant tumours. The critical challenge for the primary care physician is to identify which cases are secondary to malignancies or other serious conditions. With a good knowledge of the complex anatomy of the neck and a careful clinical history, including a complete physical examination, the different causes can be narrowed down, as well as to differentiate between significant and non-significant neck masses and select the appropriate studies. Lymphoma commonly presents as a painless enlarged lump in the neck, as in the case of the patient presented. An algorithm is provided to help practioners.

    Selection bias in case-control studies occurs when control selection is inappropriate. However, selection bias due to improper case sampling is less well recognized. We describe how to recognize survivor bias (i.e., selection on exposed cases) and illustrate this with an example study. A case-control study was used to analyze the effect of statins on major bleedings during treatment with vitamin K antagonists. A total of 110 patients who experienced such bleedings were included 18-1,018 days after the bleeding complication and matched to 220 controls. A protective association of major bleeding for exposure to statins (odds ratio [OR]: 0.56; 95% confidence interval: 0.29-1.08) was found, which did not become stronger after adjustment for confounding factors. These observations lead us to suspect survivor bias. To identify this bias, results were stratified on time between bleeding event and inclusion, and repeated for a negative control (an exposure not related to survival): blood group non-O. The ORs for exposure to statins increased gradually to 1.37 with shorter time between outcome and inclusion, whereas ORs for the negative control remained constant, confirming our hypothesis. We recommend the presented method to check for overoptimistic results, that is, survivor bias in case-control studies. Copyright © 2014 Elsevier Inc. All rights reserved.

    A large subset of persons with migraine suffers from coexisting tension-type headache and neck pain which may adversely affect the prognosis of migraine. Aerobic exercise has been shown to decrease migraine burden in these persons. Therefore, the aim of this study was to investigate whether the effect of aerobic exercise in persons with migraine and coexisting tension-type headache and neck pain can be explained by changes in pain perception. Seventy consecutively recruited persons with migraine and coexisting tension-type headache and neck pain were randomized into exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 min, three times/week for 3 months. Controls continued their usual daily activities. Pericranial tenderness, pain thresholds, supra-thresholds and temporal summation were assessed at baseline, after treatment and at follow-up (6 months from baseline). Fifty-two persons with migraine and coexisting tension-type headache and neck pain completed the study. Aerobic exercise did not induce consistent changes in nociceptive pathways measured by pericranial tenderness, pressure pain thresholds and sensitivity to electrical stimulation. The effect of aerobic exercise cannot be explained by measurable effects on the pain modulation system. Thus, the positive effect on migraine burden may rather be explained by positive alteration of avoidance behaviour. Aerobic exercise can be recommended as a safe and inexpensive migraine treatment strategy. This study adds further knowledge about the positive effect of aerobic exercise for persons with migraine and coexisting tension-type headache and neck pain. This effect cannot be measured by changes in pain modulation, but may rather be explained by positive alteration of avoidance behaviour. © 2018 European Pain Federation - EFIC®.

    Stenosis and obstruction of the internal jugular vein (IJV) sometimes occur following modified radical neck dissection or selective neck dissection, in which the IJV is preserved. The objective of this study was to assess risk factors for stenosis or obstruction of the IJV following neck dissection. A total of 58 neck dissections performed in 51 patients by the same surgeon at Gunma University Hospital were retrospectively reviewed. The relationships of the patency of the IJV with gender, side of dissection, number of lymph node metastases, invasion out of the lymph node, radiotherapy, and reconstructive method were examined. The patency of the IJV was evaluated postoperatively using enhanced computed tomography. All cases with obstruction of the IJV received postoperative radiotherapy and neck dissection on the left side. Postoperative radiotherapy was a significant risk factor for obstruction of the IJV. Free flap reconstruction was not a risk factor for stenosis and obstruction. The rate of obstruction of the IJV was significantly decreased in cases with pectoral major musculocutaneous flap reconstruction or extended supraomohyoid neck dissection in which the muscle extensively covered the IJV.

    A matched case-control study was performed to identify the etiologic factors for thyroid carcinoma in teen-agers. Twenty-seven cases and 69 controls were investigated to assess the significance of various maternal and subject factors. Irradiation during infancy was the only factor which showed a statistically significant association with the incidence of thyroid cancer in teen-agers (summary χ 2 = 8.040; d.f. = 1; P < 0.005). The estimated dose ranged from 0.2 to 40 rads on the head, neck, or chest during infancy. (author)

    2002-01-01

    A tool for analyzing ceramographic cuts of sphere beds was programmed. The parameter of interest was the neck ratio being formed during sintering. A neck investigation based on such a cross section was programmed in a way, that the cross section discs could be entered graphically, and that the necking data was extracted from this information. In a resulting graphic the neck information on the surface was overlaid and could be crosschecked with the actual visible necking data. This allowed a quality control of the extracted data but was also necessary to exclude some false solution being introduced by the principle how the data was extracted. Some test on cross sections of a Cer-Med Sphere-Bed showed good results.

    Pathological bilateral femoral neck fracture due to renal osteodystrophy is rare. This is a report of a chronic renal failure patient who had sustained bilateral intra-capsular displaced fracture neck of femur following an episode of convulsion and the difficulties encountered in early diagnosis and treatment. The pathophysiology of renal osteodystrophy and the treatment of hip fractures in patients with renal failure are also discussed. A 23 years old male patient admitted with h/o dysuria, pyuria and loss of appetite since 3 months. He was a known case of chronic renal failure and reflux nephropathy. On investigating, patient's renal parameters were high and he was started with haemodialysis. The next day patient had c/o bilateral hip pain and inability to move bilateral lower limbs following an episode of seizure. Radiograph of pelvis showed vertical sub capital fractures of bilateral neck of femur. In this patient, considering his age, general condition & prognosis, an elective surgery in the form of bilateral uncemented modular bipolar hemiarthroplasty was done. Overall risk of hip fracture among patients with chronic renal failure is considerably higher than in the general population, independent of age and gender. Simultaneous spontaneous bilateral fractures of the femoral neck are rare and a delayed diagnosis is usual. The study of etiological factors of these fractures is essential to guide us in choosing the treatment of choice. Obviously patient's age, life expectancy as well as renal co morbidity has an influence over deciding treatment and outcome.

    Hypothyroidism is a common complication when radiotherapy is part of the treatment for head and neck tumours. This study aimed to show the incidence of hypothyroidism and possible risk factors in these patients. Factors related to the population, tumour, treatment and occurrence of hypothyroidism were analysed in 241 patients diagnosed with head and neck carcinoma. Approximately 53 per cent of patients were diagnosed with radiation-induced hypothyroidism. Its occurrence was related to: tumour location, laryngeal surgery type, neck dissection type, post-operative complications, cervical radiotherapy and radiotherapy unit type (linear particle accelerator or telecobalt therapy technology). Control of thyroid function should be standardised for several years after treatment, particularly in patients with risk factors, such as those treated with telecobalt therapy, those with post-operative complications and for whom the thyroid parenchyma is included in the irradiated area (laryngeal or pharyngeal location and bilateral cervical radiation).

    To assess the impact of mechanical exposure and work related psychosocial factors on shoulder and neck pain. A prospective cohort study. 4919 randomly chosen, vocationally active men and women ages 45-65 residing in a Swedish city. Neck and shoulder pain were determined by the standardised Nordic questionnaire. Mechanical exposure was assessed by an index based on 11 items designed and evaluated for shoulder and neck disorders. Work related psychosocial factors were measured by the Karasek and Theorell demand-control instrument. High mechanical exposure was associated with heightened risk for shoulder and neck pain among men and women during follow up. Age adjusted odds ratios (OR) were 2.17 (95% confidence intervals (CI): 1.65, 2.85) and 1.59 (95% CI: 1.22, 2.06), respectively. In women, job strain (high psychological job demands and low job decision latitude) correlated with heightened risk (OR = 1.73, 95% CI: 1.29, 2.31). These risk estimates remained statistically significant when controlled for high mechanical exposure regarding job strain (and vice versa), and for sociodemographic factors. Testing for effect modification between high mechanical exposure and job strain showed them acting synergistically only in women. Job related mechanical exposure in both sexes, and psychosocial factors in women, seem independently of each other to play a part for development of shoulder and neck pain in vocationally active people. The effect of psychosocial factors was more prominent in women, which could be the result of biological factors as well as gender issues. These results suggest that interventions aiming at reducing the occurrence of shoulder and neck pain should include both mechanical and psychosocial factors.

    In general, it seems that both genetic and environmental factors play important roles in the induction of neural tube defects. Lipomyelomeningocele (LipoMMC) is a rather common type of closed neural tube defect, but only limited studies have investigated the potential risk factors of this anomaly. Therefore, the purpose of this case-control study was to investigate the risk factors involved in LipoMMC formation. Various risk factors were evaluated in 35 children between 1 month and 10 years of age with LipoMMC in a hospital-based case-control study. The 2 control arms consisted of 35 children with myelomeningocele (MMC group) and 35 children with congenital anomalies other than central nervous system problems (control group). All groups were matched for age and visited the same hospital. A structured questionnaire was used for the collection of all data, including the mothers' weight and height during pregnancy, education, reproductive history, previous abortions, and socioeconomic status, as well as the parents' consanguinity and family history of the same anomalies. Univariate analysis of the children with LipoMMC compared to the control group showed that the use of periconceptional folic acid supplementation was significantly lower in the MMC and LipoMMC groups compared to the control group. In addition, comparison of the MMC and control groups revealed statistically significant differences regarding the use of folic acid and maternal obesity. In multivariate analysis, use of folic acid in the periconceptional period and during the first trimester was an independent risk factor for LipoMMC and MMC. Furthermore, maternal obesity was a significantly positive risk factor for MMC. The probable risk factors for LipoMMC were investigated in this case-control study. Consumption of folic acid in the periconceptional period and during the first trimester is an independent protective factor against LipoMMC. It seems that larger studies are needed to examine other possible

    Neck pain is a musculoskeletal condition with high prevalence that may affect the physical, social, and psychological aspects of the individual, contributing to the increase in costs in society and business. To determine the prevalence of neck pain and associated factors in a population-based sample of adults aged 20 and more. Cross-sectional study based on a population survey. A total number of 600 individuals were interviewed in their homes, and the following data were collected: (1) participant characteristics (demographic, socioeconomic, and work-related aspects) using a pre-coded questionnaire; (2) physical activity level using the IPAQ; and (3) musculoskeletal symptoms using the Nordic questionnaire. Descriptive, bivariate, and Poisson regression analyses were performed. The prevalence of neck pain was 20.3% (95% CI 17.3-23.7). The adjusted analyses showed that individuals who were widowers or separated (PR=2.26; 1.42-5.88), had a low income (PR=1.32; 1.22-6.27) or low educational level (PR=1.83; 1.02-5.26), worked while sitting and leaning (PR=1.55; 1.08-2.40), and who reported having two or more diseases (PR=1.71; 1.55-6.31) remained associated with neck pain. This study reveals the high prevalence of neck pain and remarkable association with widowed/separated people who have low income and low educational level, who perform their occupational activities in sitting and leaning positions, and who reported having two or more diseases. Knowledge of these risk factors will contribute to the development of forms of assistance in which neck pain can be prevented and better managed.

    Dropped head syndrome (DHS) is a famous but unusual late complication of multimodality treatment for head and neck carcinoma. We reported this early-onset complication and analyzed the dose to the neck extensor muscles. We examined the records of three patients with DHS after radiotherapy. The doses to the neck extensor muscles were compared between three patients with DHS and nine patients without DHS. The mean dose to the neck extensor muscles of the three patients with DHS were 58.5 Gy, 42.3 Gy and 60.9 Gy, while the dose was <50 Gy in all nine patients in the control group. The onset of this syndrome was 5 months, 6 months and 15 months. The early-onset DHS may have something to do with dose to the neck extensor muscles. The proposed dose to the neck extensor muscles might be <46 Gy (or at least <50 Gy)

    Trigger points have been shown to be active in many myofascial pain syndromes. Treatment of trigger point pain and dysfunction may be explained through the mechanisms of central and peripheral paradigms. This study aimed to investigate whether the mind/body treatment of Neuro Emotional Technique (NET) could significantly relieve pain sensitivity of trigger points presenting in a cohort of chronic neck pain sufferers. Sixty participants presenting to a private chiropractic clinic with chronic cervical pain as their primary complaint were sequentially allocated into treatment and control groups. Participants in the treatment group received a short course of Neuro Emotional Technique that consists of muscle testing, general semantics and Traditional Chinese Medicine. The control group received a sham NET protocol. Outcome measurements included pain assessment utilizing a visual analog scale and a pressure gauge algometer. Pain sensitivity was measured at four trigger point locations: suboccipital region (S); levator scapulae region (LS); sternocleidomastoid region (SCM) and temporomandibular region (TMJ). For each outcome measurement and each trigger point, we calculated the change in measurement between pre- and post- treatment. We then examined the relationships between these measurement changes and six independent variables (i.e. treatment group and the above five additional participant variables) using forward stepwise General Linear Model. The visual analog scale (0 to 10) had an improvement of 7.6 at S, 7.2 at LS, 7.5 at SCM and 7.1 at the TMJ in the treatment group compared with no improvement of at S, and an improvement of 0.04 at LS, 0.1 at SCM and 0.1 at the TMJ point in the control group, (P algometer recordings of four trigger point locations in a cohort of chronic neck pain sufferers were significantly improved when compared to a control group which received a sham protocol of NET. Chronic neck pain sufferers may benefit from NET treatment in the relief

    2016-04-01

    The main aims of this study were to compare the neck flexor and extensor endurance and forward head posture between adolescents with and without neck pain. The secondary aims were to explore potential associations between muscles endurance, head posture and neck pain characteristics and to assess intra-rater reliability of the measurements used. Adolescents with neck pain (n = 35) and age-matched asymptomatic adolescents (n = 35) had their forward head posture, neck flexor endurance and neck extensor endurance measured using clinical tests. Intra-rater reliability was also assessed. Forward head posture and neck flexor and extensor endurance tests showed moderate to almost perfect intra-rater reliability (ICC between 0.58 and 0.88). Adolescents with neck pain showed significantly less forward head posture (neck pain = 46.62 ± 4.92; asymptomatic = 44.18°± 3.64°, p > 0.05) and less neck flexor (neck pain = 24.50 ± 23.03s; asymptomatic = 35.89 ± 21.53s, p > 0.05) and extensor endurance (neck pain = 12.6.64 ± 77.94s; asymptomatic = 168.66 ± 74.77s, p > 0.05) than asymptomatic adolescents. Results suggest that changes in posture and neck muscle endurance are a feature of adolescents with neck pain. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available People with epilepsy are more accident prone than the non-epilepsy population. Bone fractures are most often due to seizure-related falls. However, seizures themselves, in particular generalized tonic-clonic seizures, may also cause fractures, e.g. of the thoracic spine. Here, I present a man who developed focal epilepsy following a subarachnoidal hemorrhage. During a focal motor seizure with left-sided convulsions and preserved consciousness that lasted 2 hrs, he sustained a femoral neck fracture. In persons with low mineral density, as in this case, contractions associated with simple focal motor seizures may be sufficient to give rise to such a severe complication.

    Full Text Available Prior pregnancy is known to protect against development of breast cancer. Recent studies have demonstrated that pregnancy has the capacity to establish small numbers of immunologically active fetal-derived cells in the mother, a phenomenon known as fetal microchimerism (FMc. We asked whether presence of FMc, routinely acquired during pregnancy, is a protective factor for breast cancer.DNA extracts from peripheral blood specimens were obtained from a population-based case-control study of risk factors for breast cancer in women 21 to 45 years old. Specimens were tested with quantitative PCR for presence and concentrations of male DNA presumed to derive from prior pregnancies with a male fetus. Odds ratios (OR and 95% confidence intervals (CI were estimated with consideration of multiple established reproductive and environmental risk factors for breast cancer. FMc results were generated on 99 parous women, 54 with primary invasive breast cancer and 45 general population controls. FMc prevalence was 56% (25/45 and 26% (14/54 in controls and cases, respectively. Women harboring FMc were less likely to have had breast cancer (OR = 0.29, 95% CI 0.11-0.83; p = 0.02, adjusting for age, number of children, birth of a son, history of miscarriage, and total DNA tested. In addition, FMc concentrations were higher in controls versus cases (p = 0.01. Median concentrations were 2 (0-78 and 0 (0-374 fetal genomes/10(6 maternal genomes in controls and cases, respectively.Results suggest that the enigma of why some parous women are not afforded protection from breast cancer by pregnancy might in part be explained by differences in FMc. Mechanistic studies of FMc-derived protection against breast cancer are warranted.

    Nonspecific neck pain can cause considerable suffering, possible disability and reductions in quality of life and productivity. The aim of the proposed study is to evaluate the immediate effect of acupuncture on pain, cervical range of motion and electromyographic activity of the upper trapezius muscle in patients with nonspecific neck pain. A total of 12 patients with nonspecific neck pain and 12 healthy subjects will be enrolled in a randomized, single-blind crossover study. Each subject will receive two forms of treatment in random order: a single session of traditional acupuncture (acupoints: triple energizer 5, 'Wai-guan' and large intestine 11, 'Qu-chi') and sham acupuncture. To eliminate carry-over treatment effects, a one-week wash-out period will be respected between sessions. Surface electromyography will be used to determine motor control in the upper trapezius muscle before and after treatment. The outcome measures in the group with neck pain will be a numerical pain rating scale (range: 0 (no pain) to 10 (maximum pain)), documentation of the pain area on a body chart and cervical range of motion. Comparisons before and after acupuncture treatment will demonstrate whether acupoints affect the activity of the upper trapezius muscle, pain and cervical range of motion. The purpose of this randomized clinical trial is to evaluate the immediate effect of acupuncture on pain, cervical range of motion and electromyographic activity of the upper trapezius muscle in patients with nonspecific neck pain. Data will be published after the study is completed. The study will support the practice of evidence-based physical therapy for individuals with nonspecific neck pain. This trial was registered with Clinicaltrials.gov (identifier: NCT0984021 ) on 7 November 2013 ( https://clinicaltrials.gov/ct2/show/NCT01984021 ).

    Full Text Available Abstract Background Adult patients with hypothalamic-pituitary disorders have compromised quality of life (QoL. Whether this is due to their endocrine consequences (hypopituitarism, their underlying hypothalamic-pituitary disorder or both is still under debate. The aim of this trial was to measure quality of life (QoL in long-term cancer survivors who have received a radiation dose to the basal part of the brain and the pituitary. Methods Consecutive patients (n=101 treated for oropharyngeal or epipharyngeal cancer with radiotherapy followed free of cancer for a period of 4 to10 years were identified. Fifteen patients (median age 56 years with no concomitant illness and no hypopituitarism after careful endocrine evaluation were included in a case-control study with matched healthy controls. Doses to the hypothalamic-pituitary region were calculated. QoL was assessed using the Symptom check list (SCL-90, Nottingham Health Profile (NHP, and Psychological Well Being (PGWB questionnaires. Level of physical activity was assessed using the Baecke questionnaire. Results The median accumulated dose was 1.9 Gy (1.5–2.2 Gy to the hypothalamus and 2.4 Gy (1.8–3.3 Gy to the pituitary gland in patients with oropharyngeal cancer and 6.0–9.3 Gy and 33.5–46.1 Gy, respectively in patients with epipharyngeal cancer (n=2. The patients showed significantly more anxiety and depressiveness, and lower vitality, than their matched controls. Conclusion In a group of long time survivors of head and neck cancer who hade received a low radiation dose to the hypothalamic-pituitary region and who had no endocrine consequences of disease or its treatment QoL was compromised as compared with well matched healthy controls.

    Full Text Available BACKGROUND: Dengue is the most prevalent mosquito borne infection worldwide. Vertical transmissions after maternal dengue infection to the fetus and pregnancy losses in relation to dengue illness have been reported. The relationship of dengue to miscarriage is not known. METHOD: We aimed to establish the relationship of recent dengue infection and miscarriage. Women who presented with miscarriage (up to 22 weeks gestation to our hospital were approached to participate in the study. For each case of miscarriage, we recruited 3 controls with viable pregnancies at a similar gestation. A brief questionnaire on recent febrile illness and prior dengue infection was answered. Blood was drawn from participants, processed and the frozen serum was stored. Stored sera were thawed and then tested in batches with dengue specific IgM capture ELISA, dengue non-structural protein 1 (NS1 antigen and dengue specific IgG ELISA tests. Controls remained in the analysis if their pregnancies continued beyond 22 weeks gestation. Tests were run on 116 case and 341 control sera. One case (a misdiagnosed viable early pregnancy plus 45 controls (39 lost to follow up and six subsequent late miscarriages were excluded from analysis. FINDINGS: Dengue specific IgM or dengue NS1 antigen (indicating recent dengue infection was positive in 6/115 (5·2% cases and 5/296 (1·7% controls RR 3·1 (95% CI 1·0-10 P = 0·047. Maternal age, gestational age, parity and ethnicity were dissimilar between cases and controls. After adjustments for these factors, recent dengue infection remained significantly more frequently detected in cases than controls (AOR 4·2 95% CI 1·2-14 P = 0·023. INTERPRETATION: Recent dengue infections were more frequently detected in women presenting with miscarriage than in controls whose pregnancies were viable. After adjustments for confounders, the positive association remained.

    This study investigated the relative contribution of individual, workplace, psychosocial and physiological features associated with neck pain in female office workers towards developing appropriate intervention programs. Workers without disability (Neck Disability Index (NDI) score workers with neck pain and disability (NDI > or = 9/100, n=52) and 22 controls (women who did not work and without neck pain) participated in this study. Two logistic regression models were constructed to test the association between various measures in (1) workers with and without disability, and (2) workers without disability and controls. Measures included those found to be significantly associated with higher NDI in our previous studies: psychosocial domains; individual factors; task demands; quantitative sensory measures and measures of motor function. In the final model, higher score on negative affectivity scale (OR=4.47), greater activity in the neck flexors during cranio-cervical flexion (OR=1.44), cold hyperalgesia (OR=1.27) and longer duration of symptoms (OR=1.19) remained significantly associated with neck pain in workers. Workers without disability and controls could only be differentiated by greater muscle activity in the cervical flexors and extensors during a typing task. No psychosocial domains remained in either regression model. These results suggest that impairments in the sensory and motor system should be considered in any assessment of the office worker with neck pain and may have stronger influences on the presenting symptoms than workplace and psychosocial features.

  7. Clinical usefulness of a newly-developed head and neck surface coil for MR imaging

    1995-01-01

    To obtain correct diagnosis at early stages of cervical lymph node swelling, especially cases with suspected epipharyngeal carcinoma, and cerebral arterial sclerotic diseases, high-quality MR images visualizing the entire head and neck structures and vessels are of crucial importance. When obtaining images of head and neck regions using a head coil, signal intensity (SI) and signal to noise ratio (SNR) of regions below the hypopharynx are weakened. Moreover, when obtaining images of head and neck regions using an anterior neck coil, SI and SNR of upper regions of epipharynx are also weakened. In an attempt to solve these problems, we developed a new head and neck surface coil for MR imaging. With this new coil we were able to obtain better images (153 cases) from regions below the hypopharynx to the upper regions of the epipharynx in the same time as images obtained using the head coil and anterior neck coil. 2D TOF MR angiographic images (11 cases) obtained by the head and neck surface coil are superior to 2D TOF angiographic images obtained by the anterior neck coil. MR images obtained with this improved method are valuable in the evaluation and management of head and neck region disease. (author)

    There is evidence that tumor hypoxia adversely affects loco-regional tumor control and survival in head and neck cancer. The aim of the current study was to compare pretreatment tumor oxygenation measured by Eppendorf pO2 electrodes with known prognostic factors in advanced head and neck tumors after definitive radiotherapy, and to evaluate the prognostic significance of these parameters on loco-regional tumor control. Sixty-seven patients, median age 56 years (22-82), all with primary stage III-IV squamous cell carcinoma were available for survival analysis. Tumor oxygenation was described as the fraction of pO2 values=2.5 mmHg (HP2.5) and the median tumor pO2. By regression analysis HP2.5 was independent of known prognostic factors including stage, pretreatment hemoglobin (Hb) and the largest tumor diameter at the site of pO2 measurement. By Kaplan-Meier analysis loco-regional tumor control at 5 years was in favor of less hypoxic tumors using either HP2.5 or median tumor pO2 as descriptors and stratifying by the median values. Also, Hb was prognostic of loco-regional tumor control at 5 years using the median value as cut off. HP2.5 as continuous parameter was highly significant for loco-regional tumor control in a multivariate analysis. In conclusion both HP2.5 and total Hb were prognostic for loco-regional tumor control, but HP2.5 as continuous variable was independently the strongest prognostic indicator for loco-regional tumor control after definitive primary radiotherapy in advanced head and neck tumors

    (1) To examine the heritability of TMD pain and of neck pain; and (2) to estimate the potential overlap in genetic and environmental factors influencing TMD pain and neck pain. Data from 2,238 adult female twins who completed a survey on TMD pain and neck pain were analyzed. The total variance of TMD pain and neck pain was decomposed into variance attributable to additive genetic effects and nonshared environmental effects. Bivariate structural equation modeling was applied to estimate trait-specific and genetic effects shared between traits. The prevalence of TMD pain and neck pain was 8.6% and 46.8%, respectively, while 6.7% of the twins reported both TMD pain and neck pain. The phenotypic correlation between TMD pain and neck pain, based on a liability threshold model, was 0.43 (95% confidence interval [CI] 0.34 to 0.51). The heritability for TMD was 0.35 (0.17 to 0.51), and for neck pain was 0.33 (0.23 to 0.43). The genetic correlation between TMD pain and neck pain was 0.64 (0.35 to 1.00), and the environmental correlation was 0.32 (0.14 to 0.48). This study shows that variation in TMD pain and neck pain can in part be attributed to genes. The comorbidity between them is partly explained by genes that influence both traits and partly by the same environmental factors.

    Full Text Available AIM: To evaluate the role of palliative radiotherapy for symptom control in patients with locally advanced head and neck cancer. MATERIALS AND METHODS: 25 patients with stage 3 and stage 4 head and neck cancer were treated with a short course of palliative radiotherapy (30 Gray (Gy in 10 fractions over 2 weeks. Baseline symptoms were assessed using a 11 point numerical scale for pain, dysphagia, cough, insomnia and dyspnoea. The primary end point was relief of symptoms in the fourth week after radiotherapy. Percentage symptom relief was quantified by the patient using a rupee scale. RESULTS: All 22 patients with pain and 90% of patients with dysphagia, dyspnoea and disturbed sleep had greater than 50% relief in symptoms after radiotherapy. Cough was relieved in sixty percent of cases. CONCLUSION: A short course of radiation can be an effective method of symptom palliation in head and neck cancers.

    Shoulder pain and dysfunction may occur following neck dissection among people being treated for head and neck cancer. This systematic review aims to examine the prevalence and incidence of shoulder and neck dysfunction after neck dissection and identify risk factors for these post-operative complications. Electronic databases (Pubmed, CINAHL, EMBASE, Cochrane) were searched for articles including adults undergoing neck dissection for head and neck cancer. Studies that reported prevalence, incidence or risk factors for an outcome of the shoulder or neck were eligible and assessed using the Critical Review Form - Quantitative Studies. Seventy-five articles were included in the final review. Prevalence rates for shoulder pain were slightly higher after RND (range, 10-100%) compared with MRND (range, 0-100%) and SND (range, 9-25%). The incidence of reduced shoulder active range of motion depended on surgery type (range, 5-20%). The prevalence of reduced neck active range of motion after neck dissection was 1-13%. Type of neck dissection was a risk factor for shoulder pain, reduced function and health-related quality of life. The prevalence and incidence of shoulder and neck dysfunction after neck dissection varies by type of surgery performed and measure of dysfunction used. Pre-operative education for patients undergoing neck dissection should acknowledge the potential for post-operative shoulder and neck problems to occur and inform patients that accessory nerve preservation lowers, but does not eliminate, the risk of developing musculoskeletal complications.

    Vagal nerve stimulation is a safe and well-tolerated treatment for drug-resistant epilepsy. Complications and failure of the device can result from lead fracture, device malfunction, disconnection, or battery displacement and can result in a variety of symptoms. We present an interesting case of stimulator malfunction with increased impedance change seen only with a change in head position. The patient is a 25-year-old male with a vagal nerve stimulator (VNs) placed for medically refractory epilepsy who presented with neck pain and an electrical pulling sensation in his neck whenever he turned his head to the right. Initial interrogation of the VNs showed normal impedance. Subsequent interrogation with the patient's head turned found increased impedance only when the head was turned to the right. The patient had successful removal and replacement of the device with resolution of his preoperative complaints. Partial lead fracture was seen at explant. VNs malfunction can present in atypical ways. Positional maneuvers may help with its timely diagnosis. Copyright © 2018 Elsevier Inc. All rights reserved.

    We report two cases of hypothyroidism with clinical symptoms that occurred after radiotherapy for cancer of the head and neck. The first patient underwent total laryngectomy without thyroidectomy for laryngeal cancer and partial gastrectomy for gastric cancer. Radiation of the neck was carried out postoperatively. Two years later, he developed chest pain and pericardial effusion was detected, leading to a diagnosis of myxedema due to hypothyroidism. The second patient received radiotherapy alone for laryngeal carcinoma. Two months later, a low serum sodium concentration and anemia were detected, both of which proved difficult to correct. The cause of these changes was found subsequently to be hypothyroidism. From the experience of these 2 cases, we measured thyroid function in 37 patients who had received neck radiation for head and neck cancers at our hospital over the past 10 years. In 13 of the 37 patients (35%), hypothyroidism was observed. The prevalence of hypothyroidism was higher in the 13 patients treated with both radiation and surgery, with 6 (46%) showing this condition, compared with 7 of the 24 patients (29%) who received radiation alone. The risk factor responsible for hypothyroidism was not evident from statistical analysis of these cases. We consider that thyroid function should be evaluated periodically in patients who have received neck radiotherapy, as it is often difficult to diagnose hypothyroidism from clinical symptoms.

    Pain and disability are interrelated, but the relationship between pain and disability is not straightforward. The objective of this study was to investigate the relationship between neck pain (NP) intensity, NP duration, and disability based on the population-based 'Funen Neck and Chest Pain......' study. Pain intensity was measured using 11-box numerical rating scales, pain duration was measured using the Standardized Nordic Questionnaire, and disability was measured by the Copenhagen Neck Functional Disability Scale. Spearman rank correlation coefficients and logistic regression analyses were...... used to measure correlations and strength of associations between pain intensity, pain duration, and disability given domain specific characteristics (socioeconomic, health and physical, comorbidity, and variables related to consequences of NP). Neck pain was very common, but mainly mild and did...

  15. Function and structure of the deep cervical extensor muscles in patients with neck pain.

    The deep cervical extensors are anatomically able to control segmental movements of the cervical spine in concert with the deep cervical flexors. Several investigations have confirmed changes in cervical flexor muscle control in patients with neck pain and as a result, effective evidence-based therapeutic exercises have been developed to address such dysfunctions. However, knowledge on how the deep extensor muscles behave in patients with neck pain disorders is scare. Structural changes such as higher concentration of fat within the muscle, variable cross-sectional area and higher proportions of type II fibres have been observed in the deep cervical extensors of patients with neck pain compared to healthy controls. These findings suggest that the behaviour of the deep extensors may be altered in patients with neck pain. Consistent with this hypothesis, a recent series of studies confirm that patients display reduced activation of the deep cervical extensors as well as less defined activation patterns. This article provides an overview of the various different structural and functional changes in the deep neck extensor muscles documented in patients with neck pain. Relevant recommendations for the management of muscle dysfunction in patients with neck pain are presented. Copyright © 2013 Elsevier Ltd. All rights reserved.

Background & Aims of the Study: In developing countries, with increasing use of computer systems, millions of computer workers are at high risk of neck and shoulder pains. The aim of this study was to assess the relationships between work-related physical and psychosocial factors and persistent neck and shoulder pains among computer office workers. Materials & Methods : This longitudinal study with 1-year follow-up was conducted among all eligible computer office workers (n=182 of Shahroud universities (northeastern Iran in 2009-2010. “Cultural and Psychosocial Influences on Disability (CUPID” questionnaire was used to collect data on demographic characteristics, physical, organizational and psychosocial factors at work, and neck and shoulder symptoms. Chi square and logistic regression analysis was used to analyze the data through SPSS version 16. Results: Computer office workers with the mean±SD age of 32.1±6.7 years and the mean±SD weekly work hours of 47.4±8.2 participated in this study. At the baseline 39.6% of workers reported neck and shoulder pains. At one year follow-up, 59.7% of them reported neck pain and 51.3% reported shoulder pain. Significant relationships were found between persistence of neck and shoulder pains and age, gender, and decision latitude at work. Conclusions: Although neck and shoulder pains were equally prevalent among the study group, after one year follow up, persistent neck pain was more than shoulder pain. Age, gender, and decision latitude at work were identified as risk factors for both pains. References: 1. Buckle PW, Devereux JJ.

    Full Text Available Qat (Catha edulis chewing is reported to induce lesions in the buccal mucosa, irritation of the esophagus, and esophageal reflux. Case series suggest a possible etiological role in oral and esophageal cancers. This pilot study aimed to generate preliminary estimates of the magnitude and direction of the association between qat use and esophageal cancer (EC risk and to inform the logistics required to conduct a multi-center case-control study.Between May 2012 and May 2013, 73 EC cases (including 12 gastro-esophageal junction cases and 133 controls matched individually on sex, age, and residence were enrolled at two endoscopy clinics and a cancer treatment hospital in Addis Ababa. A face-to-face structured questionnaire was administered. Qat use was defined as ever having chewed qat once a week or more frequently for at least one year. Odds ratios were calculated using conditional logistic regression.Only 8% of cases resided in Addis Ababa. Qat use was more frequent in cases (36% than in controls (26%. A 2-fold elevation in EC risk was observed in ever qat chewers compared with never users in unadjusted conditional logistic regression (OR = 2.12; 95% CI = 0.94, 4.74, an association that disappeared after adjusting for differences in tobacco use, consumption of alcohol and green vegetables, education level, and religion (OR = 0.95; 0.22, 4.22. Among never tobacco users, however, a non-significant increase in EC risk was suggested in ever qat users also after adjustment. Increases in EC risk were observed with ever tobacco use, alcohol consumption, low consumption of green vegetables, a salty diet, illiteracy, and among Muslims; the four latter associations were significant.This pilot study generated EC risk estimates in association with a habit practiced by millions of people and never before studied in a case-control design. Results must be interpreted cautiously in light of possible selection bias, with some demographics such as education level

    Cervical and thoracic spinal manipulative therapy has shown positive impact for relief of pain and improve function in non-specific mechanical neck pain. Several attempts have been made to compare their effectiveness although previous studies lacked a control group, assessed acute neck pain or combined thrust and non-thrust techniques. To compare the immediate effects of cervical and thoracic spinal thrust manipulations on mechanosensitivity of upper limb nerve trunks and grip strength in patients with chronic non-specific mechanical neck pain. Randomized, single-blinded, controlled clinical trial. Private physiotherapy clinical consultancy. Eighty-eight subjects (32.09±6.05 years; 72.7% females) suffering neck pain (grades I or II) of at least 12 weeks of duration. Participants were distributed into three groups: 1) cervical group (N.=28); 2) thoracic group (N.=30); and 3) control group (N.=30). One treatment session consisting of applying a high-velocity low-amplitude spinal thrust technique over the lower cervical spine (C7) or the upper thoracic spine (T3) was performed, while the control group received a sham-manual contact. Measurements were taken at baseline and after intervention of the pressure pain threshold over the median, ulnar and radial nerves. Secondary measures included assessing free-pain grip strength with a hydraulic dynamometer. No statistically significant differences were observed when comparing between-groups in any of the outcome measures (P>0.05). Those who received thrust techniques, regardless of the manipulated area, reported an immediate increase in mechanosensitivity over the radial (both sides) and left ulnar nerve trunks (Ppain perception over the radial nerve also improved (P≤0.025). Low-cervical and upper-thoracic thrust manipulation is no more effective than placebo to induce immediate changes on mechanosensitivity of upper limb nerve trunks and grip strength in patients with chronic non-specific mechanical neck pain.

    To study protective role of pomegranate extract on radiation induced dermatitis and mucositis in head and neck cancer patients, a prospective, clinical, double blind case control study was carried out. 60 patients (30 active and controls) undergoing radiotherapy for head and neck cancer were studied for 12 months. Patients in study group were given whole fruit pomegranate extract. Each capsule contained 300 mg of whole fruit extract, each capsule contains 40% polyphenols and 27% punicalagin. Each patient was given 2 capsules every day for a period of 6 to 7 weeks. The skin and mucosal changes was graded according to the Acute Radiation Morbidity Scoring criteria (RTOG) for skin and mucous membrane. Among the 30 patients who received the pomegranate extract, 27 had grade 1, 2 had grade 2 and 1 had grade 3 dermatitis. Whereas those who did not receive the extract, 20 had grade 2 dermatitis, 7 had grade 3 dermatitis and 3 had grade 4 dermatitis. Among the 30 patients who received the pomegranate extract, 10 had grade 0, 17 had grade 1 and 3 had grade 2 mucositis. Whereas of those who did not receive the extract, 21 had grade 2 mucositis, 9 had grade 3 mucositis. The results were statistically significant. Our study is one of the first study in humans to demonstrate the effectiveness of pomegranate extract in preventing radiation dermatitis and mucositis. (author)

    Introduction: The purpose of this study was to evaluate the clinical efficacy in our daily practice, outside clinical trials, of cetuximab plus radiotherapy in a majority of treatment-naive patients with locoregionally advanced head and neck squamous cell carcinomas. Methods: A retrospective study was performed to evaluate outcomes in patients who were treated definitively with cetuximab and radiotherapy (ExRT). Patients with stage III or IV, nonmetastatic, measurable squamous cell carcinoma of the head and neck (SCCHN) were eligible. Results: There were 18 males and two females. The median age was 61 years (range from 49 to 87 years old). Concurrent radiotherapy and cetuximab was used, in first line, in 17 patients with locally advanced disease; two patients with recurrent SCCHN, who were intolerant of Cisplatin-based regimens, were treated with radiotherapy combined with weekly cetuximab; and 1 patient received cetuximab and radiotherapy postoperatively. The median time of response was 10 months (range from 2 to 24 months). A partial response was observed in 11 cases; a complete response in nine cases. The occurrence of grade 2–3 skin toxicity was observed in 11 cases. Skin toxicity was clearly correlated with a better response and the duration of the response to the treatment. The use of cetuximab in combination with radiotherapy does not increase the side effects of radiotherapy. At the end of the follow-up, 17 patients died. Conclusion: Cetuximab, with its highly targeted mechanism of action and synergistic activity with current treatment modalities, is a valuable treatment option in head and neck patients. The effect of the epidermal growth factor receptor antagonist occurs without any change in the pattern and the severity of toxicity usually associated with head and neck radiation. Cetuximab seems not to provide the most benefit for patients with oropharyngeal cancers but will in patients with T4 tumors. However, the median duration of local control was

    Full Text Available Abstract Background An ad hoc peer-review committee was jointly appointed by Drug Authorities and Industry in Germany, Austria and Switzerland in 1999/2000 to review the evidence for a causal relation between phenacetin-free analgesics and nephropathy. The committee found the evidence as inconclusive and requested a new case-control study of adequate design. Methods We performed a population-based case-control study with incident cases of end-stage renal disease (ESRD under the age of 50 years and four age and sex-matched neighborhood controls in 170 dialysis centers (153 in Germany, and 17 in Austria from January 1, 2001 to December 31, 2004. Data on lifetime medical history, risk factors, treatment, job exposure and intake of analgesics were obtained in a standardized face-to-face interview using memory aids to enhance accuracy. Study design, study performance, analysis plan, and study report were approved by an independent international advisory committee and by the Drug Authorities involved. Unconditional logistic regression analyses were performed. Results The analysis included 907 cases and 3,622 controls who had never used phenacetin-containing analgesics in their lifetime. The use of high cumulative lifetime dose (3rd tertile of analgesics in the period up to five years before dialysis was not associated with later ESRD. Adjusted odds ratios with 95% confidence intervals were 0.8 (0.7 – 1.0 and 1.0 (0.8 – 1.3 for ever- compared with no or low use and high use compared with low use, respectively. The same results were found for all analgesics and for mono-, and combination preparations with and without caffeine. No increased risk was shown in analyses stratifying for dose and duration. Dose-response analyses showed that analgesic use was not associated with an increased risk for ESRD up to 3.5 kg cumulative lifetime dose (98 % of the cases with ESRD. While the large subgroup of users with a lifetime dose up to 0.5 kg (278 cases and

    Full Text Available Purpose: Proximal migration of the ureteric double J stent is a rare but known complication. We describe three cases where a minimally invasive technique for retrieval of displaced double J stents using Amplatz™ goose-neck snare was successful. Materials and Methods: A retrospective review of patients with displaced double J stent was carried out, in whom cystoscopy guided retrieval of double J stent was attempted with the help of Amplatz goose-neck snare under radiological control. Results: All three patients were under the age of 3 years. Two patients had migrated double J stent following pyeloplasty and in one patient the double J stent was displaced during a retrograde insertion of double J stent. In all cases, retrieval of displaced double J stent was successfully achieved using Amplatz goose-neck snare. There were no postoperative complications. Conclusion: Our method of retrieval of stent from renal pelvis is simple, safe and minimally invasive. This technique is a useful and safe alternative option for retrieval of proximally migrated double J stents in children.

    The incidence of occult perifacial nodal disease in oral cavity squamous cell carcinoma is not well reported. The purpose of this study was to evaluate the incidence of isolated perifacial lymph node metastasis in patients with oral squamous cell carcinoma with a clinically node-negative neck. The study will shed light on current controversies and will provide valuable clinical and pathological information in the practice of routine comprehensive removal of these lymph node pads in selective neck dissection in the node-negative neck. Prospective analysis. This study was started in August 2011 when intraoperatively we routinely separated the lymph node levels from the main specimen for evaluation of the metastatic rate to different lymph node levels in 231 patients of oral squamous cell cancer with a clinically node-negative neck. The current study demonstrated that 19 (8.22%) out of 231 patients showed ipsilateral isolated perifacial lymph node involvement. The incidence of isolated perifacial nodes did not differ significantly between the oral tongue (7.14%) and buccal mucosa (7.75%). Incidence was statistically significant in cases with lower age group (oral squamous cell carcinoma with a clinically node-negative neck. The incidence of isolated perifacial involvement is high in cases of buccal mucosal and tongue cancers. A meticulous dissection of the perifacial nodes seems prudent when treating the neck in oral cavity squamous cell carcinoma. 4 Laryngoscope, 126:2252-2256, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

    Objective: To study the application of super-selective external carotid artery embolization in head and neck diseases. Methods: DSA and super-selective external carotid artery embolization were carried out in 41 cases of head and neck diseases including 12 cases of epistaxis, 7 nasopharyngeal fibroangioma, 1 traumatic arterial bleeding, 14 vascular malformation, and 7 malignancies. Results: No recurrence of nose bleeding after embolization of epistaxis was seen within 6-12 month follow up. The operative bleeding was reduced significantly by preoperative embolization in nasopharyngeal fibroangioma. No recurrence of bleeding was reduced significantly by preoperative embolization in nasopharyngeal fibroangioma. No recurrence of bleeding was achieved after embolization of traumatic artery. Among the case of vascular malformation, 3 were proven to be significantly efficient, 6 efficient, and 5 inefficient in the 6-12 month follow up. Among the 7 malignant cases, 3 survived more than 2 years. Conclusion: Super-selective external carotid artery embolization is safe and effective in the treatment of head and neck diseases.

    Carcinomas of the mesopharynx, hypopharynx, and larynx with early-stage primary tumor and with cervical lymph node metastasis, were treated by neck dissection for cervical metastasis and definitive irradiation of the primary tumor. In this study, the primary sites of the 16 cases were the mesopharynx (10), the hypopharynx (3), and the larynx (3). Twelve cases of early T stages (T1 or T2) and 15 cases of advanced N stages (N2 or N3) were chosen for this treatment concept. Neck lesions were controlled in all cases and all the primary tumors showed complete response at the end of the initial treatment. One case of mesopharyngeal cancer died due to recurrence of the primary tumor and one case of hypopharyngeal cancer died due to complicated lung cancer. The treatment modality for cases of early primary cancer and advanced cervical lymph node metastasis requires well-balanced strategies for both lesions. In these cases, optimal prognosis was obtained because of careful patient selection. The treatment strategy described in this paper should be considered for cases of early T tumors and advanced N tumors. (author)

    Vitamin D serum levels have been found to be related to sun exposure and diet, together with cell differentiation, growth control and consequently, cancer risk. Vitamin D receptor (VDR) genotypes may influence cancer risk; however, no epidemiological studies in sporadic breast cancer (BC) or malignant melanoma (MM) have been performed in a southern European population. In this study, the VDR gene has been evaluated in two epithelial cancers BC and MM. We have conducted an analysis in 549 consecutive and non-related sporadic BC cases and 556 controls, all from the Spanish population, and 283 MM cases and 245 controls. Genotyping analyses were carried out on four putatively functional SNPs within the VDR gene. An association with the minor allele A of the non-synonymous SNP rs2228570 (rs10735810, FokI, Met1Thr) was observed for BC, with an estimated odds ratio (OR) of 1.26 (95% CI = 1.02–1.57; p = 0.036). The synonymous variant rs731236 (TaqI) appeared to be associated with protection from BC (OR = 0.80, 95%CI = 0.64–0.99; p = 0.047). No statistically significant associations with MM were observed for any SNP. Nevertheless, sub-group analyses revealed an association between rs2228570 (FokI) and absence of childhood sunburns (OR = 0.65, p = 0.003), between the 3'utr SNP rs739837 (BglI) and fair skin (OR = 1.31, p = 0.048), and between the promoter SNP rs4516035 and the more aggressive tumour location in head-neck and trunk (OR = 1.54, p = 0.020). In summary, we observed associations between SNPs in the VDR gene and BC risk, and a comprehensive analysis using clinical and tumour characteristics as outcome variables has revealed potential associations with MM. These associations required confirmation in independent studies

    Despite the benefits of physical activity, people with arthritis are less active than the general population. The aim of this study was to determine the motivators and obstacles to physical activity for adults with arthritis. Participants were identified from the Obstacles to Action Study, a community based study of 8163 adults, which explored barriers and motivators to physical activity. A 1:1 case-control study was designed; cases were identified as those participants who reported arthritis (n = 1106). Each case was matched with an age, sex and ethnicity-matched non-arthritis control (n = 1106). Cases were less likely to achieve recommended physical activity targets (58.8% vs. 68.1% P = 0.00001). Furthermore, fewer people with arthritis believed that physical activity would help them lead healthy lives (86.7% vs. 91.3% P = 0.006) or viewed physical activity as a priority (53.8% vs. 59.8% P = 0.005). Cases were less confident in their abilities to try a new activity (37.1% vs. 43.7% P = 0.002) or maintain a healthy weight (65.0% vs. 74.3% P = 0.00001). Cases also reported greater negative impact scores for barriers to activity, particularly arthritis, accessibility, cost and discomfort while exercising. Motivators and environmental barriers to activity were similar for cases and controls. These findings persisted after adjusting for educational level, body mass index and comorbidities. People with arthritis are less active and demonstrate different attitudes toward physical activity. Although people with arthritis identify similar environmental barriers, they have different psychosocial barriers. In order to design effective physical activity programs for people with arthritis, these barriers must be specifically addressed.

    Manual therapy according to the School of Manual Therapy Utrecht (MTU) is a specific type of passive manual joint mobilization. MTU has not yet been systematically compared to other manual therapies and physical therapy. In this study the effectiveness of MTU is compared to physical therapy, particularly active exercise therapy (PT) in patients with non-specific neck pain. Patients neck pain, aged between 18-70 years, were included in a pragmatic randomized controlled trial with a one-year follow-up. Primary outcome measures were global perceived effect and functioning (Neck Disability Index), the secondary outcome was pain intensity (Numeric Rating Scale for Pain). Outcomes were measured at 3, 7, 13, 26 and 52 weeks. Multilevel analyses (intention-to-treat) were the primary analyses for overall between-group differences. Additional to the primary and secondary outcomes the number of treatment sessions of the MTU group and PT group was analyzed. Data were collected from September 2008 to February 2011. A total of 181 patients were included. Multilevel analyses showed no statistically significant overall differences at one year between the MTU and PT groups on any of the primary and secondary outcomes. The MTU group showed significantly lower treatment sessions compared to the PT group (respectively 3.1 vs. 5.9 after 7 weeks; 6.1 vs. 10.0 after 52 weeks). Patients with neck pain improved in both groups without statistical significantly or clinically relevant differences between the MTU and PT groups during one-year follow-up.

The gingival crevicular fluid concentrations of elastase and gingipain were elevated in cases vs. controls 238.8 uU/ul vs. 159.6 uU/ul p = .007 and 2.70 uU/ul vs. 1.56 uU/ul p = .001. On multivariate analysis, the mean log concentration of elastase, but not of gingipain, remained a significant predictor of preterm labor p = .0.015. Conclusion We found no evidence that clinical periodontal disease is associated with spontaneous preterm birth. Elevated gingival crevicular fluid levels of elastase were associated with preterm birth but further research is needed before this can be assumed to be a causal relationship.

    Full Text Available We evaluated the chemopreventive effect of nonsteroidal anti-inflammatory drug (NSAID use in head and neck squamous cell carcinomas (HNSCC by conducting a case-control study based on the administration of a standardized questionnaire to 71 incident HNSCC cases and same number of healthy controls. NSAID use was associated with a 75% reduction in risk of developing HNSCC. A significant risk reduction was noted in association with frequency of NSAID use. Restricting the analysis to aspirin users revealed a significant 90% reduction in risk of developing HNSCC. This study provides evidence for a significant reduction in the risk of developing HNSCC in users of NSAIDs, and specifically aspirin users.

    The aim of this study was to investigate the effectiveness of balneotherapy (BT), which is applied in addition to physical therapy (PT), in the treatment of chronic neck pain. Sixty patients with chronic neck pain were divided into study (n = 30) and control (n = 30) groups. All of the patients in both groups were treated with a 15-session standard PT program consisting of hot pack, ultrasound, and transcutaneous electrical stimulation. Patients in the study group were also treated with a 15-session BT program lasting 20 min/day in addition to the standard PT program. Visual analogue scale (VAS), modified neck disability index (mNDI), and Nottingham Health Profile (NHP) scores of all patients were evaluated at three different times as pretreatment, posttreatment, and posttreatment third week. There was no statistically significant difference between the clinical and demographic characteristics of the patients in different groups before treatment. Intragroup analysis revealed significant improvement in all parameters for both of the groups at all time intervals. Intergroup analysis uncovered the superiority of the study group. According to the results of this study, BT in combination with PT is superior to PT alone in reducing pain and disability and improving quality of life in patients with chronic neck pain.

    Purpose: To assess the role of a planned neck dissection (PND) after sequential chemoradiotherapy for patients with head-and-neck cancer with N2–N3 nodal disease. Methods and Materials: We reviewed 90 patients with N2–N3 head-and-neck squamous cell carcinoma treated between 1991 and 2001 on two sequential chemoradiotherapy protocols. All patients received induction and concurrent chemotherapy with cisplatin and 5-fluorocuracil, with or without tirapazamine. Patients with less than a clinical complete response (cCR) in the neck proceeded to a PND after chemoradiation. The primary endpoint was nodal response. Clinical outcomes and patterns of failure were analyzed. Results: The median follow-up durations for living and all patients were 8.3 years (range, 1.5–16.3 year) and 5.4 years (range, 0.6–16.3 years), respectively. Of the 48 patients with nodal cCR whose necks were observed, 5 patients had neck failures as a component of their recurrence [neck and primary (n = 2); neck, primary, and distant (n = 1); neck only (n = 1); neck and distant (n = 1)]. Therefore, PND may have benefited only 2 patients (4%) [neck only failure (n = 1); neck and distant failure (n = 1)]. The pathologic complete response (pCR) rate for those with a clinical partial response (cPR) undergoing PND (n = 30) was 53%. The 5-year neck control rates after cCR, cPR→pCR, and cPR→pPR were 90%, 93%, and 78%, respectively (p = 0.36). The 5-year disease-free survival rates for the cCR, cPR→pCR, and cPR→pPR groups were 53%, 75%, and 42%, respectively (p = 0.04). Conclusion: In our series, patients with N2–N3 neck disease achieving a cCR in the neck, PND would have benefited only 4% and, therefore, is not recommended. Patients with a cPR should be treated with PND. Residual tumor in the PND specimens was associated with poor outcomes; therefore, aggressive therapy is recommended. Studies using novel imaging modalities are needed to better assess treatment response.

    The Barrel vascular reconstruction device (Barrel VRD) is a novel stent with design features that allow endovascular coiling of wide-necked bifurcation aneurysms while preserving adjacent branches, without necessitating dual stent implantation. This study aimed to assess the safety and effectiveness of the Barrel VRD at 12-month follow-up. The Barrel VRD trial is a prospective, multicenter, observational post-marketing registry evaluating the use of the Barrel VRD for treatment of wide-necked bifurcation aneurysms. The primary effectiveness endpoint was successful aneurysm treatment measured by digital subtraction angiography with a Raymond-Roy occlusion grade of 1 or 2 in the absence of retreatment, parent artery stenosis (>50%), or target aneurysm rupture at 12 months. The primary safety endpoint was the absence of neurological death or major stroke at 12 months. Twenty patients were enrolled from December 2013 to December 2014. The device was implanted in 19 patients with 19 aneurysms (8 middle cerebral artery, 4 anterior communicating artery, 1 internal carotid artery terminus, 4 basilar artery aneurysms; mean dome height 5.7±1.91 mm; mean neck length 4.8±1.35 mm, mean dome-to-neck ratio 1.6±2.0). Coiling was performed in all cases. The primary effectiveness endpoint was achieved in 78.9% of subjects (15/19; 12 complete occlusions, 3 neck remnants), and the primary safety endpoint was 5.3% (1/19). This prospective study demonstrates that the Barrel VRD device resulted in ~80% occlusion rates and ~5% rates of neurological complications at 1 year after endovascular treatment of wide-necked bifurcation intracranial aneurysms.

    Background Epidemiologic and molecular evidences have established a strong link between high risk types of Human Papilloma Virus and a subgroup of Head and Neck Squamous Cell Carcinomas (HNSCC). We evaluated the frequency of HPV positivity in HNSCC and its relationship to demographic and some risk factor variables in an open case- control study. Methods Fourteen recently diagnosed patients with squamous cell cancer of oropharynx, hypopharynx and larynx aged 18-50 years were examined from 2008-2010 in Tabriz, Iran. HPV DNA was extracted from paraffin-embedded blocks of each patient's sample for PCR evaluation. Saliva samples of 94 control cancer-free subjects were collected for DNA analysis. Multivariable logistic regression method was used to calculate odds ratio for case-control comparisons. Results High risk HPV was detected in 6(42.8%) patients, and 6(5.3%) control subjects which was statistically significant (p<0.0001). HPV-18 was the most frequent type both in the cases and controls. HPV-16 DNA was detected in two patients of the case group, but it was not detected in any of the controls. The relation between demographic and risk factor variables was not statistically significant. Conclusion HPV infection has a significant impact on HNSCC. Despite HPV-16 stronger impact, HPV-18 is more likely to cause malignant degeneration in such cancers amongst some communities. It is vital to introduce and conduct immunization schedules in health care systems to protect communities to some extent. PMID:25780535

    The aim of this investigation was to study previous radiotherapy of malignant diseases as a risk factor for thyroid cancer. By using the Swedish Cancer Registry all cases of thyroid cancer with another malignant disease at least one year previously and living within the catchment area of the hospital were traced. During 1959-1989 a total of 1056 cases of thyroid cancer were identified. Of these, 37 had had another previous malignant disease and they constituted the cases in this study. As controls four persons with at least two malignant diseases, thyroid cancer excluded, were selected for each case from the same cancer registry. Ten (27.0%) of the 37 patients with thyroid cancer as a second tumor had earlier been irradiated with the treatment dose including the thyroid gland as compared with 34 (24.5%) of the 139 control patients. Eight of the ten cases with previous irradiation of the thyroid gland had papillary cancer. The median latency was 13 years. The estimated radiation dose in the thyroid varied between 3 and 40 Gy. External radiotherapy gave a crude odds ratio of 1.1 with 95% confidence interval = 0.5-2.8 for thyroid cancer. The weighted odds ratio was calculated to 2.3 with confidence interval = 0.5-8.9. This case-control study gave a nonsignificantly increased odds ratio for thyroid cancer in patients with external radiotherapy including the thyroid gland. 26 refs., 4 tabs

    Objective: To determine the relative frequency of clear, close and involved margins in resection specimens for head and neck malignancies. Study Design: An observational study. Place and Duration of Study: The Department of Oral and Maxillofacial Surgery, Armed Forces Institute of Dentistry, Rawalpindi and the Department of Histopathology, Armed Forces Institute of Pathology, Rawalpindi, from January 2008 to December 2010. Methodology: Tumour registers and computer data bases in the department of Histopathology of Armed Forces Institute of Pathology, Rawalpindi, were analyzed for the cases of malignancies involving head and neck region that were sent for histopathological analysis after resection in the last three years. Histopathology reports were obtained. The data regarding age, gender, site, type of malignancy and margin status (clear, close or involved) was recorded on specially designed proformas for the study and later on analyzed by using SPSS version 17.0. Results were expressed. Results: A total of 319 cases were registered in the study duration. The age of the patients ranged from 22 - 90 years (mean 59.5 + 14.1 years). Male to female ratio was 1.53:1. One hundred and thirty six (42.6%) were squamous cell carcinoma (SCC), 163 were basal cell carcinomas (BCC, 51.0%); the rest included 18 salivary gland malignancies (5.7%) and one carcino-sarcoma (0.31%) and chondrosarcoma each. All margins were found clear in 137 patients (42.9%); involved in 168 cases (52.7%) and close in 14 cases (4.4%). Conclusion: Margin clearance could not be achieved in more than 50% cases, this can lead to poor prognosis. Hence, methods should be adopted to improve the margin clearance in various head and neck malignancies. (author)

    Several trials have shown that cupping might be an effective treatment for chronic nonspecific neck pain, but little is known about the long-term effectiveness. This study aimed to investigate long-term effects of a short series of cupping; therefore additional follow-up measurements were conducted 2 years after completion of 3 studies. Participants from 3 randomized waitlist controlled trials on cupping for chronic nonspecific neck pain were followed 2 years after treatment. Outcome measures included neck pain intensity (100 mm Visual Analog Scale; VAS), functional disability (Neck Disability Index, NDI), and health-related quality of life (Short Form 36 Health Survey Questionnaire; SF-36). 133 of 150 patients had received cupping treatment and were contacted; 82 of them (61.7%) returned the follow-up questionnaires. No effect was found for neck pain intensity, but for physical function (∆ NDI: -3.15; 95% CI: -5.89; -0.41; p = 0.025) and quality of life (∆ physical component summary: 2.97; 95% CI: 0.97; 4.97; p = 0.004; ∆ bodily pain: 14.53; 95 % CI: 9.67; 19.39; p cupping effect was 8.9 ± 8.7 months with 16 patients reporting that neck pain had not yet reached the level before cupping. The majority of the patients did not continue cupping therapy, mostly due to lack of providers, costs or loss of interest. A series of cupping treatments did not influence neck pain intensity on the longer term, however significant increases were found for physical function and quality of life in patients with chronic nonspecific neck pain. Due to the considerable drop-out rate conclusions are limited. There is evidence suggesting that cupping treatment might have sustainable effects in some patients. Further randomized controlled trials with long-term follow-up are urgently needed for conclusive judgment of long-term effectiveness. © 2013 S. Karger GmbH, Freiburg.

    Despite common use of proprioceptive retraining interventions in people with chronic, idiopathic neck pain, evidence that proprioceptive dysfunction exists in this population is lacking. Determining whether proprioceptive dysfunction exists in people with chronic neck pain has clear implications for treatment prescription. The aim of this study was to synthesize and critically appraise all evidence evaluating proprioceptive dysfunction in people with chronic, idiopathic neck pain by completing a systematic review and meta-analysis. MEDLINE, CINAHL, PubMed, Allied and Complementary Medicine, EMBASE, Academic Search Premier, Scopus, Physiotherapy Evidence Database (PEDro), and Cochrane Collaboration databases were searched. All published studies that compared neck proprioception (joint position sense) between a chronic, idiopathic neck pain sample and asymptomatic controls were included. Two independent reviewers extracted relevant population and proprioception data and assessed methodological quality using a modified Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Thirteen studies were included in the present review. Meta-analysis on 10 studies demonstrated that people with chronic neck pain perform significantly worse on head-to-neutral repositioning tests, with a moderate standardized mean difference of 0.44 (95% confidence interval=0.25, 0.63). Two studies evaluated head repositioning using trunk movement (no active head movement thus hypothesized to remove vestibular input) and showed conflicting results. Three studies evaluated complex or postural repositioning tests; postural repositioning was no different between groups, and complex movement tests were impaired only in participants with chronic neck pain if error was continuously evaluated throughout the movement. A paucity of studies evaluating complex or postural repositioning tests does not permit any solid conclusions about them. People with chronic, idiopathic

    Introduction: Muscle pain has been associated with reduced maximal muscle strength, and reduced rate of force development (RFD). Strength training (ST) has shown an effect in not only normalizing muscle function but also reducing neck muscle pain. Aim: The aims of this study were to compare muscle...... function in terms of strength, force steadiness in neck flexion, as well as extension, and rate of RFD of the shoulder in tension-type headache (TTH) patients and healthy controls and to examine the correlation to tenderness. Furthermore, the aim of the study was to examine the effect of ST on neck...... steadiness (ST: p=0.011 and EP: pfunction, indicated by a lower force steadiness and RFD, compared to the healthy controls. The effect of ST was not larger than EP as both groups of TTH patients showed some improvement in neck and shoulder...

    Purpose: To evaluate our policy of performing neck dissection based on regional response after definitive radiotherapy in patients with supraglottic carcinoma and to identify the prognostic factors in this group of patients. Methods and Materials: Between 1970 and 1995, 121 patients with node-positive squamous cell carcinoma of the supraglottic larynx were treated with definitive radiotherapy. Sixty-nine percent of patients presented with 1997 AJCC Stage IV disease. The N-stage distribution was N1, 49; N2, 62; and N3, 10. The median size of the lymph nodes was 3 cm (range, 0.5-8 cm). Forty-five patients received once-a-day treatment with a median total dose of 65 Gy (range, 58.0-70.8 Gy) in 1.8-2.0 Gy per fraction over 48 days, and 76 patients received split-course accelerated hyperfractionation with a median total dose of 67.2 Gy (range, 63.2-73.6 Gy) in 1.6 Gy twice a day over 43 days. Patients whose lymph nodes were not clinically detectable at 4-6 weeks after the completion of radiotherapy (complete response) were followed without any neck dissection. Patients with persistent neck adenopathy (partial response) underwent neck dissection whenever possible. Mean follow-up of the living patients was 6.5 years. Results: Regional response was related to the size of lymph nodes at presentation. Eighty-seven percent of patients with nodal size of 3 cm or less had a complete response, whereas 43% of patients with nodal size greater than 3 cm had a partial response. The rate of regional control at 3 years for all patients in the study was 66%. The 3-year ultimate regional control rate after salvage neck dissection was 75%. A relapse in both the primary and regional sites was the most common pattern of relapse, accounting for 39% of all the failures. Local failure was associated with subsequent regional relapse with a relative risk of 4.3. For patients with completeresponse in whom postradiotherapy neck dissection was withheld, the regional control rates were 75% and 86

    In this work, we made the comparison between IMRT plan and IMPT plan for a head and neck case. We used Prowess Panther to perform IMRT plan and LAP- CERR for IMPT plan. The result showed that IMPT plan had better coverage than IMRT plan. In the IMRT plan, normal structures received higher dose with higher volume. Especially, the maximum dose of spinal cord is 31.5 Gy (RBE) using IMRT technique compared to 13.5 Gy (RBE) using IMPT technique. These results showed that IMPT is beneficial for head and neck cancer compared to IMRT technique.

    2012-01-01

    The immediate and permanent frequency of injury to the marginal mandibular branch of the facial nerve (MMN) after neck dissection has only scarcely been addressed in the medical literature. We investigated the risk of injury in 159 consecutive patients after neck dissection for various reasons...... in level I B and level II A, respectively. In 95 patients with oral cancer 13 (14%) of the cases had malfunction of the lower lip domain 2 weeks after neck dissection in level I B indicating paresis to the MMN. Follow-up analyses 1-2 years after the operation showed permanent paralysis in 4 to 7......% of the cases in whom two of them had the nerve sacrificed for oncologic reasons during the operation. In 18 patients with parotic cancer the corresponding permanent frequency of MMN paralysis was 11.1%. In 46 patients with neck dissection in level II A but not in level I B, no paresis of the MMN was registered...

    Reduced tongue strength is an important factor contributing to early and late dysphagia in head and neck cancer patients previously treated with chemoradiotherapy. The evidence is growing that tongue strengthening exercises can improve tongue strength and swallowing function in both healthy and dysphagic subjects. However, little is known about the impact of specific features of an exercise protocol for tongue strength on the actual outcome (strength or swallowing function). Previous research originating in the fields of sports medicine and physical rehabilitation shows that the degree of exercise load is an influential factor for increasing muscle strength in the limb skeletal muscles. Since the tongue is considered a muscular hydrostat, it remains to be proven whether the same concepts will apply. This ongoing randomized controlled trial in chemoradiotherapy-treated patients with head and neck cancer investigates the effect of three tongue strengthening exercise protocols, with different degrees of exercise load, on tongue strength and swallowing. At enrollment, 51 patients whose dysphagia is primarily related to reduced tongue strength are randomly assigned to a training schedule of 60, 80, or 100% of their maximal tongue strength. Patients are treated three times a week for 8 weeks, executing 120 repetitions of the assigned exercise once per training day. Exercise load is progressively adjusted every 2 weeks. Patients are evaluated before, during and after treatment by means of tongue strength measurements, fiber-optic endoscopic evaluation of swallowing and quality-of-life questionnaires. This randomized controlled trial is the first to systematically investigate the effect of different exercise loads in tongue strengthening exercise protocols. The results will allow the development of more efficacious protocols. Current Controlled Trials ISRCTN14447678.

  10. The application of a clinical prediction rule for patients with neck pain likely to benefit from cervical traction: A case report.

    Bernstetter, Andrew

    2016-10-01

    Cervical traction is a commonly utilized intervention in the treatment of patients with neck pain. In 2009, a clinical prediction rule (CPR) was developed as a way to assist clinicians in determining the patient population most likely to respond to cervical traction, though this CPR has yet to be validated. The purpose of this case report is to demonstrate the application of that CPR. The patient was a 46-year-old female with a four-week history of right-sided neck and shoulder pain, with numbness and tingling of her thumb and index finger. Treatment consisted of five sessions provided over 3 weeks. The plan of care included home mechanical cervical traction, exercise, and manual therapy. The patient achieved pain-free cervical range of motion. Neck disability index scores decreased from 28% to 6%, and the Patient-Specific Functional Scale average score improved from 5.5 to 10 out of 10. This case report demonstrates the application of a CPR to assist in deciding if cervical traction is an appropriate intervention. Further research is needed to validate the CPR and to establish the optimal mode of delivery for traction.

    2011-03-01

    The determination of the cause and manner of death for a body recovered from the water can be difficult because of a lack of autopsy findings specific for drowning. This case report describes a 30-year-old man found submerged at the bottom of a hotel pool. An autopsy revealed scleral hemorrhages and fascial hemorrhages of multiple muscles of the anterior and posterior neck bilaterally. No evidence of traumatic injury was on the surface of the body. An investigation by law enforcement found no evidence of foul play. The occurrence of petechial and neck hemorrhage in a body recovered from the water is controversial, and a review of this literature will be given. We suggest that fascial hemorrhages of the muscles of the neck, as well as cephalic hemorrhages, can be explained by drowning-related elevated central venous pressure that is communicated to the head through the valveless veins of the neck. © 2010 American Academy of Forensic Sciences.

    2017-12-01

    Hardware removal in healed trochanteric fractures (TF) in the absence of infection or significant mechanical complications is rarely indicated. However, in patients with persistent pain, prominent material and discomfort in the activities of daily living, the implant is eventually removed. Publications of ipsilateral femoral neck fracture after removal of implants from healed trochanteric fractures (FNFARIHTF) just because of pain or discomfort are rare. The purpose of this systematic review of the literature is to report on the eventual risk factors, the mechanisms, the clinical presentation, and frequency, and to pay special emphasis in their prevention. A comprehensive review of the literature was undertaken using the PRISMA guidelines with no language restriction. Case reports of FNFARIHTF and series of TF with cases of FNFARIHTF due to pain or discomfort published between inception of journals to December 2016 were eligible for inclusion. Relevant information was divided in two parts. Part I included the analysis of cases of FNFARIHTF, with the objective of establishing the eventual risk factors, mechanisms and pathoanatomy, clinical presentation and diagnosis, treatment and prevention. Part II analyzed series of TF which included cases of FNFARIHTF for assessing the incidence of femoral neck fractures in this condition. Overall 24 publications with 45 cases of FNFARIHTF met the inclusion criteria. We found that the only prevalent factors for FNFARIHTF were: 1) preexisisting systemic osteoporosis, as most patients were older and elder females, with lower bone mineral density and bone mass; 2) local osteoporosis as a result of preloading by the fixation device in the femoral neck, leading to stress protection, reducing the strain at the neck, and increasing bone loss and weakness; and 3) the removal of hardware from the femoral neck, with reduction of the failure strength of the neck. The femoral neck fractures were spontaneous, i.e. not related to trauma or

    Recent epidemiological research has revealed that gender differences exist in concussion incidence but no study has investigated why females may be at greater risk of concussion. Our purpose was to determine whether gender differences existed in head-neck segment kinematic and neuromuscular control variables responses to an external force application with and without neck muscle preactivation. Forty (20 females and 20 males) physically active volunteers participated in the study. The independent variables were gender, force application (known vs unknown), and force direction (forced flexion vs forced extension). The dependent variables were kinematic and EMG variables, head-neck segment stiffness, and head-neck segment flexor and extensor isometric strength. Statistical analyses consisted of multiple multivariate and univariate analyses of variance, follow-up univariate analyses of variance, and t-tests (P Gender differences existed in head-neck segment dynamic stabilization during head angular acceleration. Females exhibited significantly greater head-neck segment peak angular acceleration (50%) and displacement (39%) than males despite initiating muscle activity significantly earlier (SCM only) and using a greater percentage of their maximum head-neck segment muscle activity (79% peak activity and 117% muscle activity area). The head-neck segment angular acceleration differences may be because females exhibited significantly less isometric strength (49%), neck girth (30%), and head mass (43%), resulting in lower levels of head-neck segment stiffness (29%). For our subject demographic, the results revealed gender differences in head-neck segment dynamic stabilization during head acceleration in response to an external force application. Females exhibited significantly greater head-neck segment peak angular acceleration and displacement than males despite initiating muscle activity earlier (SCM only) and using a greater percentage of their maximum head-neck segment

    The purpose of this study was to describe time trends in response rates in case-control studies of cancer and identify study design factors that influence response rate. We reviewed 370 case-control studies of cancer published in 12 journals during indicator years in each of the last four decades. We estimated time trends of response rates and reasons for nonresponse in each of the following types of study subjects: cases, medical source controls, and population controls. We also estimated response rates according to characteristics of study context. Median response rates among cases and population controls were between 75% and 80% in the 1970s. Between 1971 and 2010, study response rates declined by 0.31% per year for cases and 0.78% for population controls. Only a minority of studies reported reasons for nonparticipation; subject refusal was the most common reported reason. Studies conducted in North America had lower median response rates than studies conducted in Europe. In-person and telephone interviews elicited higher response rates than mail questionnaires. Response rates from case-control studies of cancer have declined, and this could threaten the validity of results derived from these studies. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Noninvasive physical management is often prescribed for headache and neck pain. Systematic reviews, however, indicate that the evidence of its efficacy is limited. Our aim was to evaluate the effectiveness of a workplace educational and physical program in reducing headache and neck/shoulder pain.Cluster-randomized controlled trial. All municipal workers of the City of Turin, Italy, were invited to participate. Those who agreed were randomly assigned, according to their departments, to the intervention group (IG or to the control group and were given diaries for the daily recording of pain episodes for 1 month (baseline. Subsequently, only the IG (119 departments, 923 workers began the physical and educational program, whereas the control group (117 departments, 990 workers did not receive any intervention. All participants were again given diaries for the daily recording of pain episodes after 6 months of intervention. The primary outcome was the change in the frequency of headache (expressed as the proportion of subjects with a ≥50% reduction of frequency; responder rate; among the secondary outcomes there were the absolute reduction of the number of days per month with headache and neck/shoulder pain. Differences between the two groups were evaluated using mixed-effect regression models. The IG showed a higher responder rate [risk ratio, 95% confidence interval (CI] for headache (1.58; 1.28 to 1.92 and for neck/shoulder pain (1.53; 1.27 to 1.82, and a larger reduction of the days per month (95% CI with headache (-1.72; -2.40 to -1.04 and with neck/shoulder pain (-2.51; -3.56 to -1.47.The program effectively reduced headache and neck/shoulder pain in a large working community and appears to be easily transferable to primary-care settings. Further trials are needed to investigate the program effectiveness in a clinical setting, for highly selected patients suffering from specific headache types.ClinicalTrials.gov NCT00551980.

    Full Text Available Background: Gastroschisis, a birth defect characterized by herniated fetal abdominal wall, occurs more commonly in infants born to teenage and young mothers. Ischemia of the vascular vitelline vessels is the likely mechanism of pathogenesis. Given that chronic stress and violence against women are risk factors for cardiovascular disease we explored whether these may represent risk factors for gastroschisis, when they occur during pregnancy. A case-control study was conducted, with 15 incident cases of children born with gastroschisis in the Region of Murcia, Spain, from December 2007 to June 2013. Forty concurrent controls were recruited at gestation weeks 20–24 or post-partum. All mothers of cases and controls completed a comprehensive, in-person, ‘green sheet’ questionnaire on environmental exposures. Results: Mothers of children with gastroschisis were younger, smoked more cigarettes per week relative to controls, were exposed to higher amounts of illegal drugs, and suffered from domestic violence more frequently than the controls. Multivariable logistic regression analysis highlights periconceptional ‘gender-related violence’ (OR: 16.6, 95% CI 2.7 to 101.7 and younger maternal age (OR 1.1, 95% CI 1.0–1.3. Conclusions: Violence against pregnant women is associated with birth defects, and should be studied in more depth as a cause-effect teratogenic. Psychosocial risk factors, including gender-based violence, are important for insuring the health and safety of the pregnant mother and the fetus.

    Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

    2013-01-01

    The flexibility and posture of the neck in sauropod dinosaurs has long been contentious. Improved constraints on sauropod neck function will have major implications for what we know of their foraging strategies, ecology and overall biology. Several hypotheses have been proposed, based primarily on osteological data, suggesting different degrees of neck flexibility. This study attempts to assess the effects of reconstructed soft tissues on sauropod neck flexibility through systematic removal of muscle groups and measures of flexibility of the neck in a living analogue, the ostrich (Struthio camelus). The possible effect of cartilage on flexibility is also examined, as this was previously overlooked in osteological estimates of sauropod neck function. These comparisons show that soft tissues are likely to have limited the flexibility of the neck beyond the limits suggested by osteology alone. In addition, the inferred presence of cartilage, and varying the inter-vertebral spacing within the synovial capsule, also affect neck flexibility. One hypothesis proposed that flexibility is constrained by requiring a minimum overlap between successive zygapophyses equivalent to 50% of zygapophyseal articular surface length (ONP50). This assumption is tested by comparing the maximum flexibility of the articulated cervical column in ONP50 and the flexibility of the complete neck with all tissues intact. It is found that this model does not adequately convey the pattern of flexibility in the ostrich neck, suggesting that the ONP50 model may not be useful in determining neck function if considered in isolation from myological and other soft tissue data.

    Infections of odontogenic origin are the most common cause of inflammatory disease of head and neck region. Computed tomography allows for defining localization and extent of inflammatory lesions, visualizes soft tissue involvement, presence of an abscess or an osteolytic lesion around causative tooth. The aim of this study was to assess pathways, by which odontogenic infections spread into respective deep head and neck structures in computed tomography examination, taking into account the following criteria: frequency of involvement of respective deep cervical spaces, possibility to determine a probable causative tooth and concordance with the results of clinical examination. Thirty-eight patients cervicofacial inflammatory disease had undergone CT examination of head and neck region with a 64-slice CT scanner after intravenous contrast administration. Abscess was reported in 30 (79%) cases, while inflammatory infiltration was diagnosed in remaining 8 (21%) patients. There was full concordance between radiological report and intraoperative report In 33 cases (87%). The most commonly involved cervical space was masticator space – 31 patients (82%), followed by submandibular space – 27 patients (71%). Dental examination was impossible in 29 patient because of trismus. During analysis of CT studies we evaluated maxillary and mandibular alveolar processes for presence of osteolytic bone lesions around causative teeth roots and we found them in 30 cases (79%). In 32 cases (84%) cervicofacial infection were of mandibular odontogenic origin. In most cases CT study in patients suspected of odontogenic craniofacial infection revealed presence of an abscess, needing urgent surgery. Inflammatory infiltration of dental origin most frequently involves masticator space, followed by submandibular space. In most cases CT scanning allows for identification of causative teeth, especially when trismus makes detailed clinical examination impossible

    Full Text Available Background: Preeclampsia and eclampsia during pregnancy contribute to maternal and fetal morbidity as well as mortality. The identification of the role of maternal nutrition during pregnancy will help in reducing morbidity and mortality. Aims & Objective: The objective of this study is to find out the role of nutrition, in the form of total calorie, protein, fruits, iron, folic acid and calcium intake in the development of preeclampsia and eclampsia among pregnant women in a tertiary level hospital. Material Methods: After ethical approval and informed consent, 122 women who delivered beyond 22 weeks of gestation and diagnosed as preeclampsia or eclampsia were selected. Simultaneously, 122 controls with no diagnosis of preeclampsia or eclampsia were selected from the post natal ward. Cases and controls were administered the same pre-tested questionnaire containing questions related to food and micronutrient intake by cases and control. Results: Logistic regression was applied in the statistical analysis. The factors that were found to be significant predictors of risk for development of preeclampsia and eclampsia were higher calorie intake (adjusted Odds Ratio (OR 14.12 [6.41-43.23] P < 0.001, less protein intake (adjusted OR 3.87 [1.97-8.01] P < 0.001 during pregnancy. Fruits intake in both cases and controls were similar. 77.9% of cases and 84.4% of controls had taken iron tablets during their antenatal period. 75.4% of cases and 82.8% of controls had taken calcium tablets during their antenatal period. Iron and calcium intake is not significantly associated with development of preeclampsia and eclampsia. Conclusion: Higher calorie intake and less protein intake during pregnancy were associated with development of preeclampsia and eclampsia. Fruits intake, iron and calcium intake were not associated with development of preeclampsia and eclampsia

    Recent research has shown a relationship of craniomandibular disability with neck-pain-related disability has been shown. However, there is still insufficient information demonstrating the influence of neck pain and disability in the sensory-motor activity in patients with headache attributed to temporomandibular disorders (TMD). The purpose of this study was to investigate the influence of neck-pain-related disability on masticatory sensory-motor variables. An experimental case-control study investigated 83 patients with headache attributed to TMD and 39 healthy controls. Patients were grouped according to their scores on the neck disability index (NDI) (mild and moderate neck disability). Initial assessment included the pain catastrophizing scale and the Headache Impact Test-6. The protocol consisted of baseline measurements of pressure pain thresholds (PPT) and pain-free maximum mouth opening (MMO). Individuals were asked to perform the provocation chewing test, and measurements were taken immediately after and 24 hours later. During the test, patients were assessed for subjective feelings of fatigue (VAFS) and pain intensity. VAFS was higher at 6 minutes (mean 51.7; 95% CI: 50.15-53.26) and 24 hours after (21.08; 95% CI: 18.6-23.5) for the group showing moderate neck disability compared with the mild neck disability group (6 minutes, 44.16; 95% CI 42.65-45.67/ 24 hours after, 14.3; 95% CI: 11.9-16.7) and the control group. The analysis shows a decrease in the pain-free MMO only in the group of moderate disability 24 hours after the test. PPTs of the trigeminal region decreased immediately in all groups, whereas at 24 hours, a decrease was observed in only the groups of patients. PPTs of the cervical region decreased in only the group with moderate neck disability 24 hours after the test. The strongest negative correlation was found between pain-free MMO immediately after the test and NDI in both the mild (r = -0.49) and moderate (r = -0.54) neck disability

  6. Predictive factors of occult neck metastasis in patients with oral squamous cell carcinoma

    Full Text Available ABSTRACT INTRODUCTION: It is well established that cervical lymph node metastasis is the most important prognostic factor in patients with oral squamous cell carcinoma of the upper aerodigestive tract. The definition of parameters and classifications that could separate patients in groups of low, intermediate and high-risk is being attempted for several years. OBJECTIVE: The objective of this study was to determine possible predictive factors related to the occurrence of occult cervical lymph node metastasis through the analysis of histopathological reports of surgical specimens obtained after oral squamous cell carcinoma resection and selective neck dissections of patients initially classified as N0. METHODS: This was a primary, retrospective, observational, case-control study. Histopathological reports were reviewed to determine if some findings were related to the occurrence of occult lymph node metastasis. The events analyzed were oral cavity subsites, pT-stage, muscular infiltration, desmoplasia, vascular emboli, perineural infiltration, tumor thickness and compromised margins. RESULTS: Occult cervical metastasis accounted for 19.10 percent of the cases. Desmoplasia, perineural infiltration, tumor thickness and pT4a stage are predictive factors of occult neck metastasis (p-value = 0.0488, 0.0326, 0.0395, 0.0488, respectively. CONCLUSION: The accurate definition of predictive factors of occult cervical metastasis may guide the selection of patients that should be referred to radiotherapy, avoiding the unnecessary exposure of low-risk patients to radiation and allowing a better regional control of the disease in those of moderate or high risk.

    Risk factors for gallbladder cancer (GBC) except gallstones are not well known. The objective was to study the risk factors for GBC. In a case-control study, 200 patients with GBC, 200 healthy controls and 200 gallstones patients as diseased controls were included prospectively. The risk factors studied were related to socioeconomic profile, life style, reproduction, diet and bile acids. On comparing GBC patients (mean age 51.7 years; 130 females) with healthy controls, risk factors were chemical exposure [odd ratios (OR): 7.0 (2.7-18.2); p < 0.001)], family history of gallstones [OR: 5.3 (1.5-18.9); p < 0.01)], tobacco [OR: 4.1 (1.8-9.7); p < 0.001)], fried foods [OR: 3.1 (1.7-5.6); p < 0.001], joint family [OR: 3.2 (1.7-6.2); p < 0.001], long interval between meals [OR: 1.4 (1.2-1.6); p < 0.001] and residence in Gangetic belt [OR: 3.3 (1.8-6.2); p < 0.001]. On comparing GBC cases with gallstone controls, risk factors were female gender [OR: 2.4 (1.3-4.3); p = 0.004], residence in Gangetic belt [OR: 2.3 (1.2-4.4); p = 0.012], fried foods [OR: 2.5 (1.4-4.4); p < 0.001], diabetes [OR: 2.7 (1.2-6.4); p = 0.02)], tobacco [OR 3.8 (1.7-8.1); p < 0.001)] and joint family [OR: 2.1 (1.2-3.4); p = 0.004]. The ratio of secondary to primary bile acids was significantly higher in GBC cases than gallstone controls (20.8 vs. 0.44). Fried foods, tobacco, chemical exposure, family history of gallstones, residence in Gangetic belt and secondary bile acids were significant risk factors for GBC. Copyright © 2012 UICC.

    Background and Purpose Chronic neck pain is prevalent in the workplace. Research suggests that psychosocial stress may contribute to the development of neck pain by causing excessive or prolonged muscle activity in some individuals. The purpose of this case report is to describe the rationale, development, and implementation of stress management as an adjunct to standard physical therapist management of chronic neck pain in a female office worker who responded to psychosocial stress with elevated muscle activity prior to treatment. Case Description A 44-year-old female office employee with an 8-year history of chronic neck pain participated in this case report. The patient was selected from a group of research participants who demonstrated elevated electromyographic (EMG) activity of the trapezius muscle in response to simulated occupational stressors. The multidisciplinary intervention consisted of 8 physical therapy sessions, supplemented by 8 stress management sessions that included EMG biofeedback and psychotherapy to facilitate muscle relaxation. Outcomes Neck disability decreased by 50%, trait anxiety decreased by 21%, and the duration of trapezius muscle rest in the workplace increased by 56% immediately after the 8-week intervention. These improvements were maintained 6 months after treatment, and the patient reported a complete absence of neck disability at the 2-year follow-up assessment. Discussion A sustained reduction in neck disability was observed for a patient with chronic neck pain after participating in a multidisciplinary intervention that combined physical therapy and stress management approaches to facilitate muscle relaxation in the workplace. Future clinical trials are needed to assess whether stress management is a useful adjunct therapy for patients with chronic neck pain who show elevated muscle activity in response to psychosocial stress.

    2011-01-01

    Background Although neck pain is common in young adulthood, studies on predictive factors for its onset and persistence are scarce. It is therefore important to identify possible risk factors among young adults so as to prevent the development of neck pain later in life. Methods A prospective study was carried out in healthy undergraduate students. At baseline, a self-administered questionnaire and standardized physical examination were used to collect data on biopsychosocial factors. At 3, 6, 9, and 12 months thereafter, follow-up data were collected on the incidence of neck pain. Those who reported neck pain on ≥ 2 consecutive follow-ups were categorized as having persistent neck pain. Two regression models were built to analyze risk factors for the onset and persistence of neck pain. Results Among the recruited sample of 684 students, 46% reported the onset of neck pain between baseline and 1-year follow-up, of whom 33% reported persistent neck pain. The onset of neck pain was associated with computer screen position not being level with the eyes and mouse position being self-rated as suitable. Factors that predicted persistence of neck pain were position of the keyboard being too high, use of computer for entertainment Neck pain is quite common among undergraduate students. This study found very few proposed risk factors that predicted onset and persistence of neck pain. The future health of undergraduate students deserves consideration. However, there is still much uncertainty about factors leading to neck pain and more research is needed on this topic. PMID:21756362

  11. Posttraumatic Proximal Radioulnar Synostosis after Closed Reduction for a Radial Neck and Olecranon Fracture

    Directory of Open Access Journals (Sweden)

    Patrick R. Keller

    2018-01-01

    Full Text Available Posttraumatic proximal radioulnar synostosis (PPRUS is a severe complication of radial head and neck fractures known to occur after severe injury or operative fixation. Cases of PPRUS occurring after minimally displaced, nonoperatively treated radial neck injuries are, by contrast, extremely rare. Here, we present a pediatric case of PPRUS that developed after a nonoperatively treated minimally displaced radial neck fracture with concomitant olecranon fracture. While more cases are needed to establish the association between this pattern of injury and PPRUS, we recommend that when encountering patients with a minimally displaced radial neck fracture and a concomitant elbow injury, the rare possibility of developing proximal radioulnar synostosis should be considered.

    Epidemiologists have used case-control studies to investigate enteric disease outbreaks for many decades. Increasingly, case-control studies are also used to investigate risk factors for sporadic (not outbreak-associated) disease. While the same basic approach is used, there are important differences between outbreak and sporadic disease settings that need to be considered in the design and implementation of the case-control study for sporadic disease. Through the International Collaboration on Enteric Disease “Burden of Illness” Studies (the International Collaboration), we reviewed 79 case-control studies of sporadic enteric infections caused by nine pathogens that were conducted in 22 countries and published from 1990 through to 2009. We highlight important methodological and study design issues (including case definition, control selection, and exposure assessment) and discuss how approaches to the study of sporadic enteric disease have changed over the last 20 years (e.g., making use of more sensitive case definitions, databases of controls, and computer-assisted interviewing). As our understanding of sporadic enteric infections grows, methods and topics for case-control studies are expected to continue to evolve; for example, advances in understanding of the role of immunity can be used to improve control selection, the apparent protective effects of certain foods can be further explored, and case-control studies can be used to provide population-based measures of the burden of disease.

    Manual cervical distraction (MCD) is a traction-based therapy performed with a manual contact over the cervical region producing repeating cycles while patients lie prone. This study evaluated a traction force-based minimal intervention for use as an attention-touch control in clinical trials of MCD for patients with chronic neck pain. We conducted a mixed-methods, pilot randomized clinical trial in adults with chronic neck pain. Participants were allocated to three traction force ranges of MCD: low force/minimal intervention (0-20 N), medium force (21-50 N), or high force (51-100 N). Clinicians delivered five treatments over two weeks consisting of three sets of five cycles of MCD at the C5 vertebra and occiput. Traction forces were measured at each treatment. Patient-reported outcomes included a pain visual analogue scale (VAS), Neck Disability Index (NDI), Credibility and Expectancy Questionnaire (CEQ), and adverse effects. A qualitative interview evaluated treatment group allocation perceptions. We randomized 48 participants, allocating an average of five each month. Forty-five participants completed the trial with three participants lost to follow-up. Most participants were women (65%) and white (92%) with a mean (SD) age of 46.8 (12.5) years. Mean traction force values were within the prescribed force ranges for each group at the C5 and occiput levels. Neck pain VAS demonstrated a benefit for high traction force MCD compared to the low force group [adjusted mean difference 15.6; 95% confidence interval (CI) 1.6 to 29.7]. Participants in the medium traction force group demonstrated improvements in NDI compared to the low force group (adjusted mean difference 3.0; 95% CI 0.1 to 5.9), as did participants in the high traction force group (adjusted mean difference 2.7; 95% CI -0.1 to 5.6). CEQ favored the high force group. Most low force participants correctly identified their treatment allocation in the qualitative interview. No serious adverse events were

    Full Text Available Background: Preeclampsia (PE is still one of the important causes of maternal and fetal mortality in Bangladesh. Many researches have been done to identify a unique screening test that would predict the risk of developing PE before the classic symptoms appear. One of the most accessible and easiest screening tests is serum uric acid measurement. Numerous studies have demonstrated a relation between elevated maternal serum uric acid levels and adverse maternal and fetal outcome. Among several pathophysiologic factors the most commonly accepted explanation for hyperuricemia in PE is increased reabsorption and decreased excretion of uric acid.Objective: The aim of the present study was to assess the association of serum uric acid with preeclampsia.Materials and method: A case control study was conducted in the department of Biochemistry, Dhaka Medical College, Dhaka from July 2010 to June 2011. A total number of 100 pregnant women in third trimester of pregnancy attending in Obstetrics and Gynaecology department of Dhaka Medical College Hospital were selected purposively as study subjects. Among them 50 pregnant women with preeclampsia were selected as cases and 50 normal healthy pregnant women as controls.Results: Most of the study subjects were within 21 – 30 years of age group and mean age in case and control was 24.06±3.71 and 24.66±3.22 years respectively, which was not statistically different. Mean gestational age in case and control was 33.50±2.55 weeks and 33.60±2.95 weeks respectively, which was also not statistically different. Among the study subjects majority was primi in both groups (case 76%, contol 58% showing no statistical significance. Majority of the subjects in both groups were irregular in their antenatal checkup (case 52%, contol 40%. Uric acid concentration was measured in all the study subjects. The mean serum uric acid concentration in cases and controls were 7.01±1.90 mg/dl and 4.55±1.63 mg/dl respectively. This

    Although various effective antibiotics have been synthesized, deep neck abscess is still a serious and life-threatening infection. It is important to diagnose promptly and treat adequately, and contrast-enhanced CT is useful and indispensable for diagnosis. We reviewed our patients with deep neck abscess, and analyzed the location by reviewing CT images, and discussed the treatment. Surgical drainage is a fundamental treatment for abscess but if it exists in only one area such as the parotid gland space, it can be cured with needle aspiration and suitable antibiotics. (author)

    There has been much recent excitement about the possibility that some cases of psychosis may be wholly due to brain-reactive antibodies, with antibodies to N-methyl-D-aspartate receptor (NMDAR) and the voltage-gated potassium channel (VGKC)-complex reported in a few patients with first-episode psychosis (FEP). Participants were recruited from psychiatric services in South London, UK, from 2009 to 2011 as part of the Genetics and Psychosis study. We conducted a case-control study to examine NMDAR and VGKC-complex antibody levels and rates of antibody positivity in 96 patients presenting with FEP and 98 controls matched for age and sex. Leucine-rich glioma inactiviated-1 (LGI1) and contactin-associated protein (CASPR) antibodies were also measured. Notably, patients with suspicion of organic disease were excluded. VGKC-complex antibodies were found in both cases (n = 3) and controls (n = 2). NMDAR antibody positivity was seen in one case and one control. Either LGI1-Abs or CASPR2-Abs were found in three cases and three controls. Neuronal antibody staining, consistent with the above results or indicating potential novel antigens, was overall positive in four patients but also in six controls. Overall, antibody positivity was at low levels only and not higher in cases than in controls. This case-control study of the prevalence of antibodies in FEP does not provide evidence to support the hypothesis that FEP is associated with an immune-mediated process in a subgroup of patients. Nevertheless, as other bio-clinical factors may influence the effect of such antibodies in a given individual, and patients with organic neurological disease may be misdiagnosed as FEP, the field requires more research to put these findings in context.

    A 5-month-old girl with an asymptomatic left-sided neck mass was demonstrated by ultrasound and upper gastrointestinal series (UGI), and confirmed at surgery, to have a congenital piriform fossa sinus tract (CPFST) that communicated with an intrathyroidal cyst. To demonstrate a case of CPFST presenting as an asymptomatic neck mass. Nearly all cases of CPFST present with infection or pain, making this case unique. Case report and review of the literature. CPFST with an associated cyst should be added to the differential diagnosis of asymptomatic cystic neck masses in infants, especially if the cyst is intrathyroidal by ultrasound. (orig.)

    Aim: To describe condylar deformation in the temporomandibular joint (TMJ) in subjects with idiopathic condylar resorptions (ICR) and compare these changes to a healthy control group. Materials and method: CBCT scans were analyzed using anatomical points on the skull to create a reference line....... Subsequently, anatomical structures were identified on the mandible to measure the condylar axial angle, the condylar neck angle as well as the condylar width, length, and height in 25 patients with ICR and 25 controls (50 joints in each group). Secondly, cross sections of the TMJs were evaluated for deformity...... %), cavitation defect (22 %), and flattering (22 %). In the control group condylar flattening was seen in 2 %. More than 70 % of the joints with deformity changes evaluated in the sagittal and the coronal plane respectively showed deformity changes along the entire condylar surface. Conclusion: The results...
