  1. Clinical results of N0 tongue cancer treated with interstitial brachytherapy and management of occult cervical node metastases

    International Nuclear Information System (INIS)

    One hundred patients with T1-2N0 squamous cell carcinoma of the oral tongue were treated with interstitial brachytherapy between 1962 and 1983. The patients were followed for more than two years. The cumulative 5-year survival rate was 89% in T1N0 and 66% in T2N0. The relapse-free survival rate was 88% in T1N0 and 51% in T2N0. The 2-year local control rate in the primary site was 100% in T1N0 and 73% in T2N0. Cervical node metastases developed in 41% (T1N0: 33%, T2N0: 43%) of the patients. The 5-year survival rate for patients with subsequent cervical node metastases was 42%, and 92% for patients without them (p2 + PEP 6 mg/m2 x 5 days), the 2-year local control rate was 90%, the incidence of cervical node metastases was 38%, and the incidence of distant metastases was 15%. In 15 patients without chemotherapy, the corresponding figures were 93%, 20% and 7%. No statistically significant difference between the two groups was found. In conclusion, the development of cervical node metastasis worsens the prognosis of patients with T1-2N0 oral tongue cancer treated with interstitial brachytherapy. The combination with prophylactic neck irradiation or chemotherapy failed to decrease the incidence of cervical node metastases or improve survival rate. (J.P.N.)

    Background Squamous cell carcinoma (SCC) of the tongue is one of the most common cancers in the oral and maxillofacial region. To provide clinical evidence for selective neck dissection in management of cN0 patients by analyzing the characteristics and correlation of factors of occult cervical lymph node metastases (OCLNM) in patients with SCC of the tongue.Methods From 2002 to 2006, 100 consecutive patients with SCC of the tongue were reviewed by analyzing the characteristics of OCLNM, diameter of the tumor, T classifications, depth of invasion, forms of growth, pathological grade and degree of differentiation.Results The rate of OCLNM in 100 patients with SCC of the tongue was 22%. The most common region with OCLNM was level Ⅱ in the ipsilateral neck, followed by levels Ⅰ and Ⅲ. There were 51.61% (16/31) of OCLNM in level Ⅱ and 87.10% (27/31) of OCLNM in levels Ⅰ-Ⅲ. There was no significant correlation between the diameter of tumor and OCLNM (P >0.05). OCLNM was statistically significantly correlated with the depth of invasion, forms of growth, pathological grade and degree of differentiation (P <0.05). The rate of occult metastases increased with the increased pathological grade,the decreased degree of differentiation and the increased depth of invasion.Conclusions The most common regions with OCLNM in cN0 patients with SCC of the tongue were levels Ⅰ-Ⅲ in the ipsilateral neck. Supraomohyoid neck dissection should be the elective treatment to the neck in patients with cN0 SCC of the tongue by consideration of the clinical and pathological factors for the depth of invasion, forms of growth, pathological grade, and degree of differentiation.

No existe “el ángel del hogar” y, por lo tanto, no hay representación de las tareas domésticas, pero éstas son un continuo que estructuran la vida de “b”, ya que exigen un constante cuidado y orden. La teórica independencia de la mujer respecto a lo doméstico y el ser autónoma le han hecho adoptar el trabajo como forma de vida. Esta contribución cuestiona el concepto de trabajo y pone en evidencia las carencias de los términos “flexibilidad”, “autonomía”, “individualidad”, etc.

  4. Detection of cervical lymph node metastasis in head and neck cancer patients with clinically N0 neck—a meta-analysis comparing different imaging modalities

    International Nuclear Information System (INIS)

    How to properly manage clinically negative neck of head and neck cancer patients is a controversial topic. Research is now directed toward finding a method sensitive enough to bring the risk of occult metastases below 20%. The aim of this review was to compare the diagnostic accuracy of different imaging modalities, including CT, MRI, PET and US, in clinically N0 head and neck cancer patients. For this systematic review and meta-analysis, PubMed and the Cochrane Database were searched for relevant original articles published up to May 2011. Inclusion criteria were as follows: articles were reported in English; CT, MRI, PET or US were performed to identify cervical metastases in clinically N0 head and neck squamous cell carcinoma; and data were sufficient for the calculation of true-positive or false-negative values. A bivariate random effect model was used to obtain pooled sensitivity and specificity. The positive and negative test probability of neck metastasis was generated based on Bayesian theory and collected data for different pre-test possibilities. Of the 168 identified relevant articles, 7 studies fulfilled all inclusion criteria for CT, 6 studies for MRI, 11 studies for PET and 8 studies for US. There was no difference in sensitivity and specificity among these imaging modalities, except CT was superior to US in specificity. The pooled estimates for sensitivity were 52% (95% confidence interval [CI], 39% ~ 65%), 65% (34 ~ 87%) 66% (47 ~ 80%), and 66% (45 ~ 77%), on a per-neck basis for CT, MRI, PET and US, respectively. The pooled estimates for specificity were 93% (87% ~ 97%), 81% (64 ~ 91%), 87% (77 ~ 93%), and 78% (71 ~ 83%) for CT, MRI, PET and US, respectively. With pre-examination nodal metastasis probabilities set at 10%, 20% and 30%, the post-exam probabilities of positive nodal metastasis rates were 47%, 66% and 77% for CT; 27%, 46% and 59% for MRI; 36%, 56% and 69% for PET; and 25%, 42% and 56% for US, respectively.

    través de contactos sexuales. Los contactos sexuales con mujeres que ejercen el sexo comercial juegan un papel importante en la transmisión de los VPH y en algunas poblaciones estas mujeres pueden convertirse en un importante reservorio de VPH de alto riesgo. Actuando ambos como "portadores" y "vectores" de los VPH oncogénicos los hombres pueden aumentar de forma substancial el riesgo de propiciar cáncer de cérvix en sus parejas. En ausencia de programas de detección precoz, el riesgo de cáncer de cérvix en una mujer puede depender menos de su conducta sexual que de la de su marido u otras parejas sexuales. Aunque más raramente que en las mujeres, los hombres pueden también convertirse en "víctimas" de sus propias infecciones por el VPH, pues una fracción de hombres infectados tiene un riesgo aumentado de desarrollar cáncer de pene y de ano. Se ha mostrado que la circuncisión masculina puede reducir el riesgo no sólo de adquisición y transmisión del VPH genital, sino también de cáncer cervical en las parejas de hombres circuncisos. Se requieren más estudios científicos para entender mejor la historia natural y la epidemiología de las infecciones por el VPH en el hombre.

    Full Text Available El cáncer de cuello uterino se considera como un grave problema de salud pública con una alta incidencia en los países en desarrollo. La infección, permanencia y replicación del virus de papiloma humano (HPV, por sus siglas en inglés de alto riesgo a nivel cervical están relacionadas con el desarrollo del cáncer de cuello uterino. En condiciones normales, el sistema inmune es capaz de controlar y eliminar la infección por acción de la inmunidad innata, la activación de una respuesta tipo celular y la creación de anticuerpos dirigidos principalmente a las proteínas de la cápside del virión (L1 y L2. A pesar de toda la maquinaria de protección inmune del hospedero, el virus posee estrategias de evasión, conservando un número reducido de copias en las células basales proliferantes y aprovechando la corta vida natural del queratinocito. En esta revisión se tratarán los diferentes mecanismos inmunológicos del hospedero en la respuesta a la infección por el HPV.Cervical cancer is considered to be a serious public health problem having a high incidence in developing countries. High-risk cervical human papillomavirus (HPV infection, permanence and replication are closely related to the development of cervical cancer. The immune system is able to control and clear such infection in normal conditions by innate immunity action, activating a cellular response and creating antibodies, mainly directed against virion capsid proteins (L1 and L2. In spite of the host’s entire immune protection machinery, the virus can take evasion strategies, maintaining a reduced number of copies in proliferating base cells and taking advantage of the keratinocyte’s short natural life. This review attempts to show the host’s different immunological mechanisms elicited in response to HPV infection.

    Full Text Available OBJECTIVE: The purpose of this paper is to describe some of the results of the Morelos HPV Study. The main objective of the Morelos HPV Study is to evaluate the use of human papillomavirus (HPV DNA testing, as compared to the Papanicolaou (Pap test, for cervical cancer (CC screening. MATERIAL AND METHODS: The Morelos HPV Study is currently being conducted in Mexico, to examine the possibility of using HPV testing for CC screening. The HPV testing of self-collected vaginal and clinician-collected cervical specimens was evaluated as part of this study. The acceptability of the HPV testing of self-collected specimens was compared to that of the Pap test. A cost-effectiveness analysis (CEA and cost-benefit analysis (CBA was also performed. RESULTS: The Morelos HPV Study results indicate that HPV testing has a greater sensitivity to detect cervical intraepithelial neoplasia (CIN 2/3 and CC than the Pap test. Our results also indicate an over-all lower acceptability of the Pap test as compared to the self-collected procedure. The results of the CEA and CBA indicate that screening women between the ages of 20-80 for CC using some type of HPV testing is always more cost-effective than screening for CC using the Pap test. CONCLUSIONS: Our results suggest that self- and clinician-collected HPV testing could be used in CC prevention programs, as an effective complement or substitute for the Pap test.OBJETIVO: Describir algunos de los resultados del Estudio de VPH en Morelos.

    Full Text Available Cervical cancer (CC is a major public health problem in developing countries and its most significant etiological risk factor is infection by the human papillomavirus (HPV. The main approach to date for the prevention of CC has been through screening programs, using the cervical smear (PAP test to detect precursory lesions. The sensitivity and specificity of the PAP smear depend on the skills of the observer to recognize and classify a variety of cellular abnormalities. The development of early diagnoses to detect HPV infection has been a problem as cytology and colposcopy identify the lesion at an advanced stage. Therefore, molecular approaches have become more successful for early CC diagnosis. These molecular techniques recognize HPV DNA sequences by DNA hybridization, PCR-RFLP, hybrid capture and reverse line blot systems. Unfortunately, these systems cannot determine whether the HPV infection is active, latent or persistent. Thus, immunological techniques such as Western blot and ELISA have been designed to follow the immune response against the virus, and they can also be used to identify the stage of the infection. Several companies have developed, manufactured and merchandised gene-based testing systems for the screening, monitoring and diagnosis of HPV. Our review and comments focus on the critical analysis of existing products and their use in clinical practice as well as on immunological systems used mainly in research, but that may be applied in large population screening programs.El cáncer cervical (CC es el mayor problema de salud pública en países en vías de desarrollo, al ser la infección por el virus del papiloma humano (HPV el factor etiológico más importante de esta enfermedad.

    The infiltration of the parametrium represents one of the most important factors that determine the prediction and treatment of cervical carcinoma. Our objetive is to evaluate the utility of magnetic resonance imaging (MRI) in the staging of cervical carcinomas, to establish the reliability of this technique and to carry out a comparative study of the sequences used to demonstrate the parametrial invasion. We have carried out a retrospective study on 44 patients diagnosed with cervix neoplasia, using clinical exploration and performing a biopsy. the MRI studies have been carried out using a 1 Tesla magnet and the sequences used have been SE T1, Se proton density (PD) and T2 and dynamic GRE after administering gadolinium intravenously in the axial and sagital projections. The stages determined by MRI have been compared to the anatomopathological stages of the surgical specimens in cases where surgery was carried out and with the clinical stage in cases where no radical surgery was carried out. A diagnosis value of MRI has been determined to demonstrate the parametrial invasion, comparing the SE T2 sequence with the dynamic GE sequence with gadolinium. We calculate the volume of the tumour in the MRI studies to evaluate the difference of the volume between patients with tumoral stages that are clinically surgical and not surgical. MRI determines the invasion of the parametrium with a sensitivity of 88.8%, a specificity of 80% a positive value of 76.1%, a negative predictive value of 90.9% and a reliability of 83.7%. For the SE T2 sequences the sensitivity was 86.6%, the specifity 80%, the posistive predictive value 81.25%, the negative predictive value 85.7% and the reliability 83.3%.

    Full Text Available Cervical cancer is a major public health problem, as it is the second most common cancer in women world-wide after breast cancer. About 80% of the half a million cases estimated to occur annually in the world, occur in developing countries. The epidemiological evidence linking human papillomavirus (HPV to cervical cancer is reviewed. It is concluded that over 90% of cervical cancers can be attributed to certain HPV types. HPV 16 accounts for the highest proportion (50% followed by HPV 18 (12%, HPV 45 (8% and HPV 31 (5%. The associations with these HPV types are very b and consistent with odds ratios over 15 in all case-control studies in high- and low-risk countries for cervical cancer. However, HPV is not a sufficient cause of this malignancy; certain cofactors are necessary for a proportion of HPV persistent infections to eventually progress to cancer. These include host factors such as histocompatibilidad types and immunological response, hormonal influences and infections with other sexually transmitted agents such as Chlamydia trachomatis. In addition, results from our studies carried out in Spain and Colombia support the hypothesis that male carriers of HPV play an important role in the development of cervical cancer in their wives. The recognition of the central role of HPV in cervical cancer has far-reaching implications for the primary and secondary prevention of this malignancy. Prophylactic and therapeutic HPV vaccines are now under development and HPV typing is being integrated into screening programmes in pilot studies in a few developed countries. In developing countries, well conducted conventional screening programmes remain the best approach for the control of cervical cancer until a safe and efficient HPV vaccine can be used in the general population.El cáncer del cérvix constituye un problema importante de salud pública y es el más común en el mundo, después del de mama.

    Full Text Available In the last two decades, the cervical cancer puzzle has become a coherent description that includes the identification of human papillomavirus (HPV as the sexually transmitted etiologic agent and the characterization of the major determinants of HPV acquisition. Triage studies have consistently shown that HPV testing is more sensitive that repeated cytology in identifying underlying high-grade lesions in women with atypical scamous cells of undetermined significance (ASCUS. Studies that reflect primary screening conditions have shown that the sensitivity of HPV tests is higher than standard cytology in detecting high-grade lesions whereas the specificity is similar only in women aged 30-35 and above. HPV vaccines have an intrinsic attraction as a preventive strategy in populations with limited resources. However, vaccines designed to widespread use are still in development and testing phases. Time is ripe for exploring in depth the clinical implications of current achievements and to devise novel strategies for the prevention of cervical cancer.En las ultimas dos décadas, el enigma del cáncer cervical (CaCu ha comenzado a ser dilucidado y actualmente se ha identificado a la infección por virus de papiloma humano (VPH como su agente etiológico transmitido sexualmente, y se han caracterizado los principales determinantes de infección por VPH. Estudios epidemiológicos han mostrado consistentemente que las pruebas de determinación de ADN de VPH son más sensibles que la citología repetida para la identificación de lesiones de alto grado en mujeres con diagnóstico de células escamosas atípicas de significado indeterminado (ASCUS. Diversos estudios que evalúan el tamizaje primario en CaCu, han mostrado que la sensibilidad de las pruebas de VPH es más alta que la citología estándar para detectar lesiones de alto grado, donde la especificidad es similar sólo en mujeres con edades entre 30 y 35 años o mayores.

    Full Text Available Durante el desarrollo del cáncer cervicouterino se inducen mecanismos para evadir el sistema inmune, como son la disminución de la expresión de moléculas de antígeno mayor de histocompatibilidad I y la secreción de citocinas por las células tumorales. Como consecuencia de ello, la estimulación de linfocitos T citotóxicos (LTC y cooperadores (TC, de células asesinas naturales (AN y macrófagos es muy deficiente. Para inducir una respuesta inmune efectiva contra el tumor, se requiere la estimulación simultánea de múltiples componentes del sistema inmune: por vía sistémica la estimulación de LTC y TC contra epítopos del virus del papiloma humano, y en un nivel local, la inducción de la secreción de citocinas por el tumor, para aumentar el procesamiento y la presentación de blancos tumorales, así como la estimulación de los linfocitos, AN y macrófagos que infiltran el tumor.Several mechanisms to evade the immune system are induced during cervical cancer development, including the decrease of expression of class I HLA molecules and secretion of specific cytokines by tumoral cells. Consequently, the stimulation of cytotoxic (CTL and helper (TH T lymphocytes, as well as the natural killer (NK cells and macrophages is very poor. The induction of immune response against tumors needs the stimulation of multiple components of the immune system: systemic stimulation of CTL and TH against Human Papilloma Virus epitopes and directly in the tumor the secretion of specific cytokines to increase the antigen processing and presentation of tumoral targets, and the stimulation of lymphocyte, NK cells and macrophages that infiltrate tumors.

    We study chiral anomalies in $\\mathcal N=(0, 1)$ and $(0, 2)$ two-dimensional minimal sigma models defined on generic homogeneous spaces $G/H$. Such minimal theories contain only (left) chiral fermions and in certain cases are inconsistent because of "incurable" anomalies. We explicitly calculate the anomalous fermionic effective action and show how to remedy it by adding a series of local counter-terms. In this procedure, we derive a local anomaly matching condition, which is demonstrated to be equivalent to the well-known global topological constraint on $p_1(G/H)$. More importantly, we show that these local counter-terms further modify and constrain "curable" chiral models, some of which, for example, flow to nontrivial infrared superconformal fixed point. Finally, we also observe an interesting relation between $\\mathcal N=(0, 1)$ and $(0, 2)$ two-dimensional minimal sigma models and supersymmetric gauge theories. This paper generalizes and extends the results of our previous publication arXiv:1510.04324.

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

    Full Text Available Today, "persistent" infections by certain types of human papillomavirus (HPV are considered necessary for developing cervical cancer. Producing efficient vaccines against these viruses may eventually lead to a great reduction in incidence and mortality rates of this cancer. In the case of HPV, the production of traditional vaccines usually based in dead or attenuated viruses is not possible due in part to the lack of systems where large quantities of viral particles could be obtained. Fortunately, the expression of the late L1 protein alone, or in combination with L2, leads to the generation of structures resembling true virions that have been called virus-like particles (VLPs and constitute excellent candidates as prophylactic vaccines. VLPs have shown to be very immunogenic, and have prevented development of natural or challenged infections in both animal systems and humans. Recently, HPV16 VLPs were shown to be very efficient to prevent the development of "persistent" infections, as determined by PCR assays, in a large group of vaccinated women. Therapeutic vaccines, on the other hand, are expected to have an impact on advanced lesions and residual illness, by taking advantaje of the fact that early E6 and E7 genes are thought to be constitutively expressed in cervical tumors and precursor lesions. Finally, DNA-based vaccines could represent a useful alternative for preventing infections by genital HPV.Actualmente, las infecciones "persistentes" por algunos tipos del virus del papiloma humano se consideran como necesarias para desarrollar cáncer cervicouterino. Por ello, el desarrollo de vacunas eficientes contra estos virus se ha considerado de suma importancia para poder eventualmente ayudar a controlar esta enfermedad, en países donde los programas de detección oportuna no han dado aún los resultados deseados. En el caso de estos virus no es posible el desarrollo de vacunas tradicionales, las cuales están basadas generalmente en el

    Full Text Available Como las pruebas de imagen son poco apropiadas, el síndrome del latigazo cervical (SLC ha de diagnosticarse y seguirse mediante la anamnesis y la exploración física del lesionado. La constelación de trastornos puede clasificarse en cinco niveles, indicadores de gravedad, mientras que la frecuencia y la intensidad de la cervicalgia permiten el seguimiento del SLC y establecer el alta clínica. Se propone un cuestionario para recoger los datos más relevantes para el diagnóstico y el pronóstico del enfermo. La previsión de indemnización por los daños permite sospechar que puedan exagerarse las lesiones y muchos artículos refutan la importancia del SLC. Sin embargo, tienen limitaciones metodológicas o científicas apreciables. Según las investigaciones, aproximadamente un 20 % de los afectados estará curado en una semana, el 50 % en un mes, el 70 % en 6 meses y el 80 % en dos años. Uno de cada seis sufrirá incapacidad laboral parcial o completa seis meses después del traumatismo. Aunque distintos datos biológicos, psíquicos, sociales y del accidente seleccionan a los lesionados con mayor riesgo de cronificación, el modelo biológico de lesión propone que esta depende de la capacidad de recuperación del órgano lesionado. Un esguince muscular podrá recuperarse en semanas o pocos meses, pero la lesión de los discos, las articulaciones interapofisarias, las cápsulas articulares, etc. seguramente causarán dolor e incapacidad crónicos. La revisión termina comentando algunos aspectos de la terapia relacionados directamente con la evaluación forense de las lesiones.

  2. Promising treatment outcomes of intensity-modulated radiation therapy for nasopharyngeal carcinoma patients with N0 disease according to the seventh edition of the AJCC staging system

    International Nuclear Information System (INIS)

    Intensity-modulated radiation therapy (IMRT) provides excellent locoregional control for nasopharyngeal carcinoma (NPC), and has gradually replaced two-dimensional conventional radiotherapy as the first-line radiotherapy technique. Furthermore, in the new seventh edition of the American Joint Committee on Cancer (AJCC) staging system, retropharyngeal lymph nodes were upgraded from N0 to N1 disease as a result of their negative impact on the distant metastasis-free survival (DMFS) rates of NPC. This retrospective study was conducted in order to review the treatment outcomes and patterns of failure in NPC patients with N0 disease after IMRT in order to effectively guide treatment in the future. We retrospectively reviewed data from 506 biopsy-proven nonmetastatic NPC patients. There were 191 patients with negative cervical lymph node involvement. According to the seventh edition of the American Joint Committee on Cancer (AJCC) staging system, 110 patients (21.7%) were staged with N0 disease, and 81 patients (16.0%) were reclassified with N1 disease due to the presence of RLN metastasis. All patients received IMRT as the primary treatment. In patients with negative cervical lymph node involvement, distant metastasis-free survival (DMFS) was significantly higher in patients without retropharyngeal lymph node (RLN) metastasis than those with RLN metastasis (95.9% vs. 88.1% respectively, P = 0.04). For N0 disease, the 5-year overall survival (OS), local relapse-free survival (LRFS), nodal relapse-free survival (NRFS) and DMFS rates were 93.8%, 97.1%, 99.1% and 95.9%, respectively. For T1N0, T2N0, T3N0 and T4N0, OS was 97.8%, 100%, 93.8% and 76.9%, LRFS was 100%, 92.9%, 100% and 88.9% and DMFS was 96.6%, 90.9%, 100% and 93.3%, respectively. OS and LRFS were higher in T1-3 N0 patients than T4N0 patients (P < 0.01 and P = 0.01, respectively). The seventh edition of the AJCC N-staging system improves prognostic accuracy by upgrading RLN metastasis to N1 disease. IMRT

    PURPOSE: To compare sentinel lymph node biopsy, magnetic resonance imaging (MRI), Doppler ultrasonography, and palpation as staging tools in patients with T1/T2 N0 cancer of the oral cavity. MATERIAL AND METHODS: Forty consecutive patients were enrolled (17 F and 23 M, aged 32-90 years), 24 T1 and 16 T2 cN0 squamous cell carcinoma of the oral cavity. Palpation was carried out by two observers prior to inclusion. MRI, gray-scale and Doppler ultrasonography were performed. Lymphoscintigraphies were done after peritumoral injections of 99mTc labelled rheniumsulphide nanocolloid, followed by sentinel lymph node biopsy guided by a gamma probe and Patent Blue. Palpation, Doppler ultrasonography, MRI, and sentinel lymph node biopsy were compared to a combination of histopathology and follow-up. Diagnostic testing was performed using the x2 test. RESULTS: Histopathological examination revealed metastatic spread to the neck in 14 of 40 patients. One patient had bilateral neck disease. Sentinel lymph node biopsy and ultrasonography were performed in 80 neck sides of 40 patients and MRI in 70 neck sides (5 patients were claustrophobic). SN revealed suspicious lymph nodes in 12 necks, ultrasonography in 23 necks, and MRI in 9 necks. The positive predictive value of sentinel lymph node biopsy was 100%, ultrasonography 57%, and MRI 56%. The respective negative predictive values were 96%, 96%, and 85%. The sensitivity of sentinel lymph node biopsy 80% was comparable to ultrasonography 87%, but the sensitivity of MRI 36% was low. The specificities were 100%, 85%, and 93%, respectively. By combined sentinel lymph node biopsy and ultrasonography the overall sensitivity could have been 100%. CONCLUSION: Sentinel lymph node biopsy improved staging of patients with small N0 oral cancers. Combined sentinel lymph node biopsy and Doppler ultrasonography may further improve staging. MRI and simple palpation results were poor.

    Persistent rapid up and down frequency chirping modes with a toroidal mode number of zero (n=0) have been observed in the JET tokamak when energetic ions, with a mean energy {approx}500keV, were created by high field side ion cyclotron resonance frequency heating. This heating method enables the formation of an energetically inverted ion distribution function that allows ions to spontaneously excite the observed instability, identified as a global geodesic acoustic mode. The interpretation is that phase space structures form and interact with the fluid zonal flow to produce the pronounced frequency chirping.

METHODS:Population-based cross-sectional study with self-weighted two-stage cluster sampling conducted in the cities of Fortaleza (Northeastern Brazil and Rio de Janeiro (Southeastern Brazil in 2002. Subjects were women aged 25-59 years in the last three years prior to the study. Data were analyzed through Poisson regression using a hierarchical model. RESULTS: The proportion of women who did not undergo the Pap smear test in Fortaleza and Rio de Janeiro was 19.1% (95% CI: 16.1;22.1 and 16.5% (95% CI: 14.1;18.9, respectively. Higher prevalence ratios of cervical cancer screening failure in both cities were seen among women with low education and low per capita income, old age, unmarried, who never underwent mammography, clinical breast examination, and blood glucose and cholesterol level testing. Smokers also had lower screening rates compared to non-smoker women and this difference was only statistically significant in Rio de Janeiro. CONCLUSIONS:The study findings point to the need of intervention focusing particularly women in worse socioeconomic conditions and access to healthcare, old-aged and unmarried. Education activities must prioritize screening of asymptomatic women and early diagnosis for symptomatic women and access to adequate diagnostic methods and treatment should be provided.OBJETIVO:Analizar factores asociados a la no realización del examen de Papanicolaou.

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

    BACKGROUND: As carriers of filaggrin gene (FLG) mutations may have a compromised cervical mucosal barrier against human papillomavirus infection, our primary objective was to study their risk of cervical cancer. METHODS: We genotyped 586 cervical cancer patients for the two most common FLG...... mutations, R501X and 2282del4, using blood from the Copenhagen Hospital Biobank, Denmark. Controls (n = 8050) were genotyped in previous population-based studies. Information on cervical cancer, mortality and emigration were obtained from national registers. Odds ratios (OR) were estimated by logistic...... and stratification by cancer stage. RESULTS: The primary results showed that FLG mutations were not associated with the risk of cervical cancer (6.3% of cases and 7.7% of controls were carriers; OR adjusted 0.81, 95% CI 0.57-1.14; OR adjusted+ weighted 0.96, 95% CI 0.58-1.57).

    Full Text Available OBJECTIVE: To estimate the benefits, cost-effectiveness (i.e., value for money, and required financial costs (e.g., affordability of adding human papillomavirus (HPV vaccination to Peru's cervical cancer screening program. METHODS: Evidence (e.g., coverage, delivery costs from an HPV vaccination demonstration project conducted in Peru was combined with epidemiological data in an empirically calibrated mathematical model to assess screening (HPV DNA testing three to five times per lifetime and HPV vaccination under different cost, coverage, and efficacy assumptions. Model outcomes included lifetime risk of cancer reduction, cancer cases averted, lives saved, average life expectancy gains, short-term financial costs, and discounted long-term economic costs. RESULTS: Status quo low levels of screening (e.g., cytologic screening at 10.0% coverage reduced lifetime risk of cervical cancer by 11.9%, compared to not screening. Adding vaccination of preadolescent girls at a coverage achieved in the demonstration program (82.0% produced an additional 46.1% reduction, and would cost less than US$ 500 per year of life saved (YLS at ~US$ 7/dose or ~US$ 1 300 at ~US$ 20/dose. One year of vaccination was estimated to cost ~US$ 5 million at ~US$ 5/dose or ~US$ 16 million at ~US$ 20/dose, including programmatic costs. Enhanced screening in adult women combined with preadolescent vaccination had incremental cost-effectiveness ratios lower than Peru's 2005 per capita gross domestic product (GDP; US$ 2 852, in 2009 US$, and would be considered cost-effective. CONCLUSIONS: Preadolescent HPV vaccination, followed by enhanced HPV DNA screening in adult women, could prevent two out of three cervical cancer deaths. Several strategies would be considered "good value" for resources invested, provided vaccine prices are low. While financial costs imply substantial immediate investments, the high-value payoff should motivate creative mechanisms for financing and scale-up of

This is a qualitative study, realized with twenty women with a diagnosis of cervical cancer. The survey had as theoretical support the integrality of attention to the health. To collect data it was used the information from Information System of Cervical Cancer and a semi-structured interview. Characteristics of age, education, frequency to the medical consultation and the interval of prevent exams were identified. The findings make possible to say that women still have difficulty in considering the importance of pre-cancer in order to precocious detection and prevention of cervical cancer. The challenge to reach integrality is in the necessity of rethinking knowledge and professional practices in the care to women, independent of the reason which led them to the health service.

  16. Radiotherapeutic management and results of T1N0, T2N0 carcinoma of the oral tongue: Evaluation of boost techniques

    International Nuclear Information System (INIS)

    This paper presents the total experience of radiation therapy of early carcinoma of the oral tongue at the Massachusetts General Hospital over a span of 25 years. External beam radiotherapy with various boost techniques were used including interstitial implant, and intra-oral cone (IOC) using kilovoltage (250 kV HVL 1.53 mm Cu) radiations or low megavoltage electron beam. We evaluated our results of boost techniques for treatment of patients with T1N0 and T2N0 lesions and determined the 5-year actuarial local control rates of these treatment methods. From 1960-1978, 49 patients were treated by implant and 20 by intra-oral cone kilovoltage radiation. From 1979-1985, 73 patients were treated by intra-oral cone electron beam with minimal follow-up of 2 years. The 5-year actuarial local control rates for T1N0 and T2N0 lesions showed 54% after implant, 50% after intra-oral cone kilovoltage, and 86% after intra-oral cone electron beam boost with a p value of 0.0001. For the T1N0 lesions, the corresponding rates were 77%, 62%, and 90%, and for T2N0 lesions the rates were 54%, 43%, and 85%, respectively. In the absence of a prospective randomized trial, direct comparison of various boost techniques is not possible due to selection factor for therapy, increased clinical and technical expertise, and improvement in equipment. Therefore, no definitive conclusions can be made regarding optimum boost therapy. The data presented herein suggest that intra-oral cone electron beam boost technique is superior to interstitial implant for boosting early carcinoma of the tongue

Se exploran la valorización del placer sexual, del ejercicio de la sexualidad tras la menopausia, y las formas de prevenir el cáncer cervical, a través de las respuestas de un grupo de mujeres beneficiarias de Consultorios de Atención Primaria de Santiago de Chile, atrasadas en su examen de Papanicolaou por lo menos un año. Se observa que la valoración expresada por las mujeres de su sexualidad es más positiva que en estudios anteriores en Chile, y que hay disposición de las mujeres a aprender más sobre su cuerpo, aún cuando un grupo minoritario mantiene visiones negativas sobre la sexualidad. Esto abre perspectivas para una acción educativa de los servicios de salud, referida no sólo a mejorar las coberturas del examen de Papanicolaou, sino a mejorar la calidad de vida de las mujeres.The purpose of the study is to explore some characteristics of women's perspectives on their sexuality, as there is information that associates the population's sexual culture with the incidence of cervical cancer. The value of sexual pleasure, sexual activity after menopause, and ways of preventing cervical cancer are explored. Data were obtained from a group of women attending primary care clinics in Santiago, Chile, and who were at least a year late for their Pap smear. The value women ascribed to sexuality was more positive than in previous studies performed in Chile. Women want to learn more about their bodies, although a minority still have negative perspectives concerning their sexuality. These results offer health services the opportunity to carry out educational activities with the purpose not only of increasing the number of women who have Pap smears but also of improving their quality of life.

    Full Text Available The potential use of vaccines for the human papillomavirus (HPV in the prevention and treatment of cervical cancer is a possibility in the near future. Close to 20 genotypes of HPV, of the 75 that have been identified, infect the femine genital tract, but four subtypes (16, 18, 31 and 45 have been associated in close to 80% of cervical cancers. this article proposes that in order to design an effective prophylactic vaccine against HPV infection, an adequate immune response should be guaranteed through four goals; a activation of antigens present in the cell; b overcoming the host response and viral genetic variability in the T cell response; c generation of high levels of T and B memory cells; and d persistence of antigens.El potencial uso de vacunas de virus del papiloma humano (VPH en la prevención y tratamiento del cáncer cervical posiblemente será implementado durante los próximos años.

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Ident...

  11. Lymphatic mapping to tailor selective lymphadenectomy in cN0 tongue carcinoma: beyond the sentinel node concept

    International Nuclear Information System (INIS)

    Cervical lymph node status is the most important pathological determinant of prognosis and decision making in head and neck squamous cell carcinoma (SCC). The aim of this study was to demonstrate that lymphoscintigraphy (LS) can supply a complete map of the lymphatic drainage before surgery, allowing planning of the type of intervention and serving to guide lymphadenectomy. The study population comprised 14 patients with T2-4 SCCs of the tongue and clinically negative lymph nodes in the neck (cN0) who were scheduled to undergo tumour resection and selective level I-IV neck dissection extended to level V. LS was performed in all patients following the injection of 99mTc-colloidal sulphide in three aliquots around the primary lesion. Dynamic, static and tomographic images of the head and neck were acquired. The operative specimens were subjected to lymphoscintigraphic evaluation. Preoperative and postoperative imaging results were compared with the pathological findings. All nodes were examined using haematoxylin-eosin staining. Preoperative LS was successful in all patients. Preferential pathways of lymphatic drainage were identified: level II of the neck was the most common lymphatic drainage pattern, followed by levels IV and III. Contralateral drainage occurred in 11 patients and in two of them metastatic nodes were found on the contralateral side. Metastases were observed only in radioactive lymph nodes. LS is able to supply a complete map of the lymphatic drainage before surgery, making it possible to tailor selective neck dissection to each individual patient based on the results of preoperative mapping, thereby sparing healthy lymphatic tissue and reducing surgery-related morbidity.

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

  13. A first-principles study of PuN (0 0 1) surface properties

    International Nuclear Information System (INIS)

    The properties of PuN (0 0 1) surface have been investigated using all-electron full-potential linearized augmented plane wave plus local orbitals basis (FP-LAPW+lo) method at both scalar- and fully- relativistic levels, with and without spin-polarization. The ground state of PuN (0 0 1) surface is found to be ferromagnetic with spin–orbit coupling (FM + SO). At the ground state, the semi-infinite surface energy and average work function for PuN (0 0 1) surface are predicted to be 1.12 J/m2 and 2.62 eV, respectively. At three layers of formula units and beyond, the PuN (0 0 1) surface properties including total energies per N-formula unit, surface energy, work function and magnetic moment converge, indicating that a 3-layer slab can be used to model PuN (0 0 1) surface to a good approximation. The localization of the 5f electron states is pronounced at the top surface layer while bulk-like behavior is exhibited at the second and deeper layers

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

  2. Sphincter preservation in distal CT2N0 rectal cancer after preoperative chemoradiotherapy

    International Nuclear Information System (INIS)

    Preoperative chemoradiotherapy is usually not indicated for cT2N0 rectal cancer. Abdominoperineal resection is the standard treatment for distal rectal tumors. The aim of the study was to evaluate the actual sphincter-preservation rate in patients with distal cT2N0 rectal cancer given neoadjuvant chemoradiotherapy. Data were retrospectively collected for all patients who were diagnosed with distal cT2N0 rectal cancer at a tertiary medical center in 2000–2008 and received chemoradiotherapy followed by surgery (5–7 weeks later). Thirty-three patients (22 male) of median age 65 years (range, 32–88) were identified. Tumor distance from the anal verge ranged from 0 to 5 cm. R0 resection with sphincter preservation was accomplished in 22 patients (66%), with a 22% pathological complete response rate. Median follow-up time was 62 months (range 7–120). There were no local failures. Crude disease-free and overall survival were 82% and 86%, respectively. Factors associated with sphincter preservation were tumor location (OR = 0.58, p = 0.02, 95% CI = 0.37-0.91) and pathological downstaging (OR = 7.8, p = 0.02, 95% CI = 1.35-45.85). Chemoradiotherapy was well tolerated. High rates of sphincter preservation can be achieved after preoperative chemoradiotherapy for distal cT2N0 rectal cancer, with tolerable toxicity, without compromising oncological outcome

    2016-09-01

    Cervical myelopathy is the most common cause of acquired spinal cord compromise. The concept of degenerative cervical myelopathy (DCM), defined as symptomatic myelopathy associated with degenerative arthropathic changes in the spine axis, is being introduced. Given its progressive nature, treatment options have to be chosen in a timely manner. Surgical options include anterior discectomy and fusion (ACDF), anterior corpectomy and fusion (ACCF), arthroplasty (in highly select cases), posterior laminectomy with/without fusion, and laminoplasty. Indications for each should be carefully considered in individual patients. Riluzole, a sodium-glutamate antagonist, is a promising option to optimize neurologic outcomes post-surgery and is being examined in the CSM-Protect Randomized Controlled Trial. Preoperative risk assessment is mandatory for prognostication. Sagittal alignment is known to play an important role to optimize surgical outcome. Guidelines for optimal management of DCM are in process. In principle, all but the mildest cases of DCM should be offered surgery for optimal outcome. PMID:27250040

    We study the behavior of two-dimensional supersymmetric connections of n copies of O (N ) models with an N =(0 ,1 ) heterotic deformation generated by a right-moving fermion. We develop the model in analogy with the connected N =(0 ,2 ) C P (N -1 ) models for the case of a single connecting fermionic superfield. We calculate the effective potential in the large-N limit and determine the vacuum field configurations. Similarly to other supersymmetry (SUSY) connected models we find that SUSY is unbroken under certain conditions despite the vanishing of the Witten index. Specifically, this preservation of SUSY occurs when we have an even number n of O (N ) families. As in previous cases we show that this result follows from a Zn symmetry under a particular exchange of the O (N ) families. This leads to a definition of a modified Witten index, which guarantees the preservation of SUSY in this case.

A torticollis having lasted for more than a week should be recognized, because it can be treated by skull traction. Cervical spine fractures in children under school age are very rare, the most common being a fracture of the base of the dens of the second cervical vertebra. Cervical spine instability is almost always associated with an underlying disease. PMID:27400588

    Full Text Available We present quantum chemical investigations on magnetic properties of several Co6On (n=0–9,12 nanoparticles. The results of calculations show, that only Co6, and Co6O8 particles display paramagnetic properties while other nanoparticles investigated reveal diamagnetic ones. The reason of the derivative paramagnetizability is discussed here. Calculations reveal that the stability of these compounds increases with the increase of the number of O atoms. The limit when the future increase of oxygen atoms does not change binding energy per atoms remarkably is found. The reason why the O atoms could stabilize the Co nanoparticles and change magnetic properties of them is discussed.

  20. The critical release rates for the dissociating gas N204/N02/N0

    International Nuclear Information System (INIS)

    Dissociating vapour systems have certain characteristics which make them attractive as coolants, notably a large effective specific heat which is significantly greater than that for the individual components of the gas mixture, and also an enhanced boundary layer heat transfer coefficient resulting from the physical characteristics of thermal dissociation. In part these effects ensure that a dissociating gas has a greatly improved thermal capacity and heat transfer capability when compared with most inert gases. In this report the critical release rates for the dissociating vapour system N204-N02-N0 are established, principally in the two phase region, and the thermodynamics of nitrogen tetroxide are examined.

  2. Cervical metastatic glioblastoma multiforme

    International Nuclear Information System (INIS)

    Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumour in adults. In spite of the hostile nature of glioblastoma multiforme (GBM), extracranial spread is not a common event. With improving management choices and survival times, reports of extracranial occurrence of GBM have increased. Most commonly these metastases are to the lungs, lymph nodes, neck, skull, scalp, liver, and bones; may be evident on routine follow-up images of the original lesion. Head and neck metastasis of GBM can be debilitating. We present a case of cervical metastasis of GBM and discuss possible mechanisms of extraneural spread of this tumour. (author)

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    2015-01-01

    We study two-dimensional $\\mathcal{N}{=}(0,2)$ supersymmetric gauged linear sigma models (GLSMs) using supersymmetric localization. We consider $\\mathcal{N}{=}(0,2)$ theories with an $R$-symmetry, which can always be defined on curved space by a pseudo-topological twist while preserving one of the two supercharges of flat space. For GLSMs which are deformations of $\\mathcal{N}{=}(2,2)$ GLSMs and retain a Coulomb branch, we consider the $A/2$-twist and compute the genus-zero correlation functions of certain pseudo-chiral operators, which generalize the simplest twisted chiral ring operators away from the $\\mathcal{N}{=}(2,2)$ locus. These correlation functions can be written in terms of a certain residue operation on the Coulomb branch, generalizing the Jeffrey-Kirwan residue prescription relevant for the $\\mathcal{N}{=}(2,2)$ locus. For abelian GLSMs, we reproduce existing results with new formulas that render the quantum sheaf cohomology relations and other properties manifest. For non-abelian GLSMs, our met...

    The structures of neutral and cationic Cr3On0,+ (n = 0-3) clusters are calculated with density functional theory employing the BLYP and BP86 functionals. Gas-phase CrnOm clusters are produced by laser vaporization and characterized with time-of-flight mass spectrometry. The ionization energies of Cr3On (n = 0-2) are determined with threshold photoionization spectroscopy using tunable laser light in the 4.5-5.60 eV range. On the basis of a comparison between experimental and calculated ionization energies, ground-state structures were assigned. The influence of sequential addition of oxygen on the exchange coupling between the chromium atoms is investigated providing evidence for enhanced ferromagnetic coupling of chromium atoms in both the neutral and cationic Cr3On0,+ clusters. This evidence of superexchange interaction through oxygen extends earlier ideas to control the magnetic interactions in the chromium dimer via chemical reactions with oxygen toward larger chromium clusters.

    Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective. PMID:23262983

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

    Full Text Available Cervical spondylosis is a common, chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck as well as the contents of the spinal canal. Common clinical syndromes associated with cervical spondylosis include cervical pain, cervical radiculopathy and/or mielopathy. This study show the main principles, indication and side effects of tuina in cervical spondylosis´ treatment; tuina is one of the external methods based on the principles of Traditional Chinese Medicine (TCM, especially suitable for use on the elderly population and on infants. While performing Tuina, the therapist concentrates his mind, regulates his breathing, and actuates the Qi and power of his entire body towards his hands. For a better result is recommended to try to combine acupuncture with tuina treatment. Tuina can help relieve the pain associated with spondylosis. After this kind of treatment, the symptomes produced by irritated nerves and sore muscles can find some relief. Tuina helps patients with cervical spondylosis regain muscle control, nerve function and flexibility, all through the restoration of the life force flow.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    Full Text Available Como las pruebas de imagen son poco apropiadas, el síndrome del latigazo cervical (SLC ha de diagnosticarse y seguirse mediante la anamnesis y la exploración física del lesionado. La constelación de trastornos puede clasificarse en cinco niveles, indicadores de gravedad, mientras que la frecuencia y la intensidad de la cervicalgia permiten el seguimiento del SLC y establecer el alta clínica. Se propone un cuestionario para recoger los datos más relevantes para el diagnóstico y el pronóstico del enfermo. La previsión de indemnización por los daños permite sospechar que puedan exagerarse las lesiones y muchos artículos refutan la importancia del SLC. Sin embargo, tienen limitaciones metodológicas o científicas apreciables. Según las investigaciones, aproximadamente un 20 % de los afectados estará curado en una semana, el 50 % en un mes, el 70 % en 6 meses y el 80 % en dos años. Uno de cada seis sufrirá incapacidad laboral parcial o completa seis meses después del traumatismo. Aunque distintos datos biológicos, psíquicos, sociales y del accidente seleccionan a los lesionados con mayor riesgo de cronificación, el modelo biológico de lesión propone que esta depende de la capacidad de recuperación del órgano lesionado. Un esguince muscular podrá recuperarse en semanas o pocos meses, pero la lesión de los discos, las articulaciones interapofisarias, las cápsulas articulares, etc. seguramente causarán dolor e incapacidad crónicos. La revisión termina comentando algunos aspectos de la terapia relacionados directamente con la evaluación forense de las lesiones.Since imaging tests are not appropriate, whiplash associated disorders (WAD need to be diagnosed and followed up using anamnesis and physical examination of the patient. Signs and symptoms of lesion can be grouped into five severity category levels, while monitoring the frequency and intensity of neck pain may establish the moment of recovery from WAD. A

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the laser-radiation combined therapy for T2N0M0 laryngeal-glottic cancer in order to preserve the larynx. The subjects consisted of 52 patients with T2N0M0 laryngeal-glottic cancer treated with laser-radiation combined therapy between 1980 and 1999. Patients ranged in age from 40-88 years, with a median of 70 years, and included 51 men and one woman. During this period, treatment was administered with different radiation devices (60Co or 4 MV-X ray), and 40-72 Gy (median, 60Gy) of radiation therapy were administered. Tumor and treatment characteristics were correlated with local control at a median follow-up of 61 months (range 12-210 months). Concurrent chemotherapy was administered to 32 patients; 29 were treated with 5-FU and vitamin A (FAR), and 3 were treated with low-dose CDDP. Post treatment vocal function was examined in 37 patients. The voice was evaluated in terms of four parameters: maximum phonation time (MPT), mean air flow rate during phonation over a comfortable duration (MFR), fundamental frequency range of phonation (F0 range), and sound pressure level range of phonation (SPL range). The five-year cause-specific-survival rate was 98.0%, and the local control rate was 91.8%. Three of 4 patients who had locally relapsed were administered total laryngectomy as salvage therapy. One patient was administered the tracheostomy for late complication. The actuarial laryngeal preservation rate was 92.3%. We did not find any significant relationship between local relapse and extent of disease, subglottic extension, or anterior commissure involvement. Concurrent chemotherapy was not a significant prognostic factor. Laser debulking followed by radiation therapy did not change the voice significantly except the F0 range. We conclude that the laser-radiation combined therapy for T2N0M0 laryngeal-glottic cancer was effective therapy for not only preservation of the voice but also for vocal function. (author)

To assess the risk of cervical intraepithelial neoplasia grades 2, 3 or higher (CIN 2/3+ for women with normal cytology and concurrent high-risk human papillomavirus infection (HR-HPV. MATERIAL AND METHODS. We examined 2 200 women every 6 months for an average of 9 years. Cervical smears and samples for HPV DNA were obtained at each visit. Absolute risk of subsequent CIN2/CIN3+ was estimated using the Kaplan-Meier method. RESULTS. The absolute risk of CIN2/CIN3+ among HR-HPV-positive women with normal Pap smear results was 1.06% (95%CI, 0.57-2.20, 5 times higher the risk among all women with normal Pap smears (0.20%; 95%CI, 0.12-0.32 but 7 times lower than that for women with HR-HPV infection and LSIL (7.24%; 95%CI, 3.78-15.2.

  16. Magnetic influence on thermoelectric properties of CrO0.1N0.9

    International Nuclear Information System (INIS)

    Thermoelectric polycrystalline chromium oxynitride CrO0.09(3)N0.90(7) (with cubic symmetry and space group Fm-3m) samples were successfully prepared by thermal ammonolysis of chromium oxide. This potential n-type thermoelectric material shows a temperature dependence of the Seebeck coefficient (S = -48 μV K-1 at 300 K) that is typical for degenerate semiconductors; the electrical resistivity (ρ300 ∼ 2.8 mΩ cm), however, is highly influenced by the grain boundaries and low density (∼60%) of the sample. The material exhibits a clear antiferromagnetic-paramagnetic transition simultaneously with an orthorhombic-cubic structural transition at TN = 262 K. The magnetic transition affected the material's thermal conductivity, electrical resistivity, Seebeck coefficient, magnetic moment and specific heat. Heat capacity measurements at low temperatures revealed the predominance of the magnetic contribution due to spin waves.

  17. Tumor budding is a strong and reproducible prognostic marker in T3N0 colorectal cancer.

    LENUS (Irish Health Repository)

    Wang, Lai Mun

    2012-02-01

    BACKGROUND: Tumor budding along the advancing front of colorectal adenocarcinoma is an early event in the metastatic process. A reproducible, prognostic budding scoring system based on outcomes in early stage colorectal cancer has not been established. DESIGN: One hundred twenty-eight T3N0M0 colorectal carcinoma patients with known outcome were identified. Tumor budding was defined as isolated tumor cells or clusters of <5 cells at the invasive tumor front. Tumor bud counts were generated in 5 regions at 200x by 2 pathologists (conventional bud count method). The median bud count per case was used to divide cases into low (median=0) and high budding (median > or =1) groups. Forty cases were reevaluated to assess reproducibility using the conventional and a novel rapid bud count method. RESULTS: Fifty-seven (45%) carcinomas had high and 71 (55%) had low budding scores. High budding was associated with an infiltrative growth pattern (P<0.0001) and lymphovascular invasion (P=0.005). Five-year cancer-specific survival was significantly poorer in high compared with low budding groups: 63% versus 91%, respectively, P<0.0001. Multivariate analysis demonstrated tumor budding to be independently prognostic (hazard ratio=4.76, P<0.001). Interobserver agreement was at least equivalent comparing the conventional to the rapid bud count methods: 87.5% agreement (kappa=0.75) versus 92.5% agreement (kappa=0.85), respectively. CONCLUSIONS: Tumor budding is a strong, reproducible, and independent prognostic marker of outcome that is easily assessed on hematoxylin and eosin slides. This may be useful for identifying the subset of T3N0M0 patients at high risk of recurrence who may benefit from adjuvant therapy.

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT...

  6. PtMn3N0.25: A potential candidate for spintronic applications by ab initio calculations

    International Nuclear Information System (INIS)

    PtMn3N0.25 has been synthesized 36 years ago by Kren and coworkers [E. Kren, G. Kadar, M.M. Barberon, R. Fruchart, Int. J. Magn. 341 (1971) 344] but this compound remains unexplored till date. In this paper, we present a theoretical study of PtMn3N0.25 system, based on the ab initio method. We investigate the structural, electronic and magnetic properties of PtMn3N0.25 in two phases: hexagonal close packed and cubic. We find that the ferromagnetic phase is the most stable for both phases. Their metallic nature is determined through the calculations of the electronic properties. Furthermore the calculated magnetic moments hint to promising potential spintronic applications of hcp and cubic-PtMn3N0.25 as an important magnetic compound

    Full Text Available Background: In multilevel spinal cord compression caused by cervical spondylosis, surgeonsface the choice of performing a posterior route as a laminectomy orlaminoplasty, or an anterior route as multiple adjacent interbody decompressionsor corpectomies. The anterior cervical operation is not considered bysome clinicians because of concerns about complications and the complexityof multilevel anterior cervical surgery.Methods: In this retrospective study, 14 patients with multilevel cervical spondylosiswho were operated on via an anterior route were enrolled to evaluate thecomplexity, safety, and clinical results. The collected parameters were operationtime, blood loss, hospital days, and early and late complications forevaluating the operative complexity, radiographic follow-up for evaluatingfusion, graft problems, implants problems, and the recovery rate using theJapanese Orthopaedic Association score (JOA score for evaluating the operativeresults.Results: The mean operation time was 363.4 min, and blood loss was 431.4 ml. Anearly complication was noted in 1 patient with combined deep vein thrombosisand a pulmonary embolism. Late complications were screw breakage in1 patient and screw loosening in 5 patients. The mean duration of follow-upwas 21.9 months. The mean recovery rate of the JOA score was 38.8% postoperativelyand 51.9% at the final follow-up. The fusion rate was 100% inthis series.Conclusions: Anterior cervical decompression and fusion for multilevel stenosis requires alonger operation time than posterior procedures; however, the clinical resultsare satisfactory.

  8. Analysis of digitized cervical images to detect cervical neoplasia

    2004-05-01

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    Full Text Available Multilevel cervical degenerative disc disease is well known in the cervical spine pathology, with radicular syndromes or cervical myelopathy. One or two level cervical herniated disc is common in adult and multilevel cervical degenerative disc herniation is common in the elderly, with spinal stenosis, and have the same cause: the gradual degeneration of the disc. We report the case of a patient with two level cervical disc herniation (C4 – C5 and C5 – C6 treated by anterior cervical microdiscectomy both levels and fusion at C5 – C6; after five years the patient returned with left C7 radiculopathy and MRI provided the image of a left C6 – C7 disc herniation, he underwent an anterior microsurgical discectomy with rapid relief of symptoms. Three-level cervical herniated disc are rare in adults, and the anterior microdiscectomy with or without fusion solve this pathology.

    Today we can state that in spite of a considerable number of cervical osteochondrosis studies, there is a lack of research devoted to analysis of its course. There is no correlation between initial expert evaluations of cervical osteo-chondrosis cases and further course of pathological process. Goal of the research is to develop system of course prognosis of cervical osteochondrosis taking into account environmental infuence, heredity, living conditions, psychological profle of patient’s personality. Materials and methods. Dynamics of degenerative-dystrophic changes progressing of cervical vertebrae in 236 patients was analyzed. Results. Received data demonstrated that probability of stage I changing to stage II, III and IV depended on patients’ sex, age and type of labour activity, frequent supercooling and stress. Probability of fast progression of cervical osteochondrosis (5-year cycle of stage I changing to stage III and IV was to a great extent associated with heredity, urban living, presence of endocrine system diseases, syndrome of nonspecifc dysplasia of connective tissue and low indices of quality of life. Conclusion. Proposed system allows making prognosis of morphologic changes in spinal cord, and is based on radiation methods of verifcation without taking into consideration dynamics of neurological symptomatology.

    Full Text Available Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2% were males and 49 (45.8% were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years.

    Background Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets.Methods A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation.Results In this series, there was statistically significant difference (P<0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However,unilateral cervical locked facets dislocation can be reduced by posterior open reduction.Conclusions Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    Cervical spine injuries of children, though rare, have a high morbidity and mortality. The pediatric cervical spine is anatomically and biomechanically different from that of adults. Hence, the type, level and outcome of cervical spine injuries in children are different from those seen in adults. Normal developmental variants seen in children can make evaluation of the pediatric cervical spine challenging. This article reviews the epidemiology of pediatric cervical spine trauma, normal variants seen in children and specific injuries that are more common in the pediatric population. We also propose an evidence-based imaging protocol to avoid unnecessary imaging studies and minimize radiation exposure in children. (orig.)

  7. Myelopathy hand in cervical radiculopathy

    International Nuclear Information System (INIS)

    The so-called 'myelopathy hand', or characteristic finger paralysis, often recognized in cervical compression myelopathy, has been considered a unique manifestation of cervical myelopathy. We used our original grip and release test, a 15-second test in which finger motion is captured with a digital camera, to investigate whether cervical radiculopathy has the same characteristics as myelopathy hand. Thirty patients with pure radiculopathy, id est (i.e.), who had radiating arm pain and evidence of corresponding nerve root impingement on X-ray images or MRI scans, but did not have spinal cord compression, served as the subjects. In contrast to other radiculopathies, C7 radiculopathy was manifested by a significant reduction in the number of finger motion cycles on the affected side in comparison with the unaffected side, the same as in myelopathy hand. Uncoordinated finger motion was significantly more frequent on the affected side in C6 radiculopathy than on the unaffected side. These findings contradict the conventional notion that myelopathy hand is a unique manifestation of cervical myelopathy, but some radiculopathies manifested the same kinds of finger paralysis observed in myelopathy hand.

    Cervical radiculopathy describes pain in one or both of the upper extremities, often in the setting of neck pain, secondary to compression or irritation of nerve roots in the cervical spine. It can be accompanied by motor, sensory, or reflex deficits and is most prevalent in persons 50 to 54 years of age. Cervical radiculopathy most often stems from degenerative disease in the cervical spine. The most common examination findings are painful neck movements and muscle spasm. Diminished deep tendon reflexes, particularly of the triceps, are the most common neurologic finding. The Spurling test, shoulder abduction test, and upper limb tension test can be used to confirm the diagnosis. Imaging is not required unless there is a history of trauma, persistent symptoms, or red flags for malignancy, myelopathy, or abscess. Electrodiagnostic testing is not needed if the diagnosis is clear, but has clinical utility when peripheral neuropathy of the upper extremity is a likely alternate diagnosis. Patients should be reassured that most cases will resolve regardless of the type of treatment. Nonoperative treatment includes physical therapy involving strengthening, stretching, and potentially traction, as well as nonsteroidal anti-inflammatory drugs, muscle relaxants, and massage. Epidural steroid injections may be helpful but have higher risks of serious complications. In patients with red flag symptoms or persistent symptoms after four to six weeks of treatment, magnetic resonance imaging can identify pathology amenable to epidural steroid injections or surgery.

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

  16. Impact of additional cervical dedicated 18FDG-PET-CT on the management of head and neck squamous cell carcinoma

    International Nuclear Information System (INIS)

    Aim of the study: To investigate the therapeutic impact of additional cervical dedicated 18F.D.G.-PET-CT on the management of head and neck squamous cell carcinoma (H.N.S.C.C.). Materials and methods: Thirty patients with H.N.S.C.C. underwent a [18F]-F.D.G.-PET-CT standard, whole-body scan completed by a cervical dedicated protocol. Two physicians blindly reviewed the exams and the results were discussed with surgeons to determine the therapeutic impact of the dedicated protocol. Result: Among 30 patients, only four (13%) discordant results were registered by the both observers, and two more by only one observer (k = 0.75, S.D. = 0.08). As to the four patients: 1) a N0 staged patient on whole body (W.B.) exam was upstaged to N2b in cervical PET (obese patient, whole-body exam with poor quality), 2) for a second patient, no node was described on whole-body scan, but one lymph node in each cervical chain was observed in focused PET, with low standardized uptake value (S.U.V. value), 3) in the other two cases, cervical PET scan upstaged from N2a to N2b and from N2a to N2c (S.U.V. < 3), without any influence on treatment management. Conclusion: Our results show that additional cervical dedicated PET-CT does not modify the management of patients with H.N.S.C.C. when compared to whole-body PET-CT, except for particular obese or N0 patients, allowing to reduce patient CT radiation dose and time-consuming PET acquisition.

    The aim of this study was to describe the method and the value of cervical discography as correlated with the MR findings. Twenty-one discs in 11 consecutive patients who underwent cervical discography were analyzed. MR and CT discography (CTD) were performed in all patients. Discography was performed after swallowing barium for visualizing the pharynx and the esophagus to prevent penetration. We also analyzed the preceding causes of the subjects' cervical pain. The results of the pain provocation test were classified into concordant pain, discordant pain and a negative test. MRI was analyzed according to the T2-signal intensity (SI) of the disc, disc height, annular bulging and disc herniation. The CTD was analyzed for degeneration or radial tear of the disc, epidural leakage of the contrast agent and pooling of the contrast agent at the periphery of the disc. The pain provocation tests were correlated with the MR and CTD findings. We used the chi-square test to analyze the results. Concordant pain was observed in 14 cases, discordant pain in 3 cases and there were negative tests in 4 cases. There were no complications related to the procedure. Four patients had undergone anterior cervical fusion and four patients that developed after traffic injuries. The decreased T2-SI and annular bulging on MRI, disc degeneration and peripheral pooling of the contrast agent on CT were significantly correlated with pain provocation. When the diagnosis of disc disease is difficult with performing MRI, cervical discography with using swallowed barium solution to reduce the penetration of the esophagus or hypopharynx may play be helpful. The decreased T2-SI and annular bulging on MRI correlated significantly with a positive result on the pain provocation test.

    Background It was reported that telomerase expression is closely associated with cellular immortality and cancer. This study was designed to investigate the relationship between telomerase expression and the carcinogenesis of cervical cancer, the possible use of telomerase as a marker of cervical intraepithelial neoplasia (CIN) progression or regression, and the natural history of CIN. Methods Telomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in cervical scrapings and biopsy samples obtained from 105 cases affected with various cervical conditions, including chronic cervicitis (n=20), CIN (n=64, 16 cases of CIN Ⅰ , 20 cases of CIN Ⅱ, and 28 cases of CIN Ⅲ ), and invasive squamous cell carcinoma (n =21 ).Results In exfoliated cell samples, telomerase activity was detected in 5 of 20 (25. 0% ) cases of cervicitis, 10 of 16 (62.5%) cases of CIN Ⅰ , 11 of 20 (55.0%) cases of CIN Ⅱ, 23 of 28 (82.1%) cases of CIN Ⅲ, and 13 of 21 (61.9%) cases of carcinoma. In cervical biopsy samples, telomerase activity was detected in 6 of 20 (30. 0%) cases of cervicitis, 8 of 16 (50. 0%) cases of CIN Ⅰ , 9 of 20 (45.0%) cases of (CIN Ⅱ, 27 of 28 (96. 4%) cases of CIN Ⅲ, and 20 of 21 (95. 2%) cases of carcinoma. Telomerase activation was significantly higher in CIN samples than in cervicitis samples. Telomerase activity was detected at similar frequency in samples from cervical scrapings and cervical biopsies.Conclusion These results seem to suggest that telomerase expression may be associated with carcinogenesis of the cervix. TRAP assay of cervical scraping samples could be used to monitor and predict the development of CIN in clinical practice.

    Instrumentation of the cervical spine enhances stability and improves arthrodesis rates in children undergoing surgery for deformity or instability. Various morphologic and clinical studies have been conducted in children, confirming the feasibility of anterior or posterior instrumentation of the cervical spine with modern implants. Knowledge of the relevant spine anatomy and preoperative imaging studies can aid the clinician in understanding the pitfalls of instrumentation for each patient. Preoperative planning, intraoperative positioning, and adherence to strict surgical techniques are required given the small size of children. Instrumentation options include anterior plating, occipital plating, and a variety of posterior screw techniques. Complications related to screw malposition include injury to the vertebral artery, neurologic injury, and instrumentation failure. PMID:27097300

    Despite the development of screening and of a vaccine, cervix cancer is a major cause of cancer death in young women worldwide. A third of women treated for the disease will recur, almost inevitably leading to death. Functional imaging has the potential to stratify patients at higher risk of poor response or relapse by improved delineation of disease extent and tumor characteristics. A number of molecular imaging biomarkers have been shown to predict outcome at baseline and/or early during therapy in cervical cancer. In future this could help tailor the treatment plan which could include selection of patients for close follow up, adjuvant therapy or trial entry for novel agents or adaptive clinical trials. The use of molecular imaging techniques, FDG PET/CT and functional MRI, in staging and response assessment of cervical cancer is reviewed. PMID:26859085

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

    International Nuclear Information System (INIS)

    69 patients with clinical signs of cervical myelopathy were examined using magnetic imaging (T1- and T2-suspended tomograms of the sagittal and transverse section using a device with 0.04 T field intensity). Vertebral disk hernias were revealed in 35 patients, compression of the spinal cord with metastases into vertebral body in 2, extramedullary tumor in 11, intramedullary tumor in 9, and syringomyelia in 12 patients. T2-suspended tomograms proved to be more informative due to their higher sensitivity to aqueous content. T1-suspended tomograms help assess the degree of spinal cord compression and the direction of the disk protrusion.

    Full Text Available Fertility can be preserved after conservative cervical surgery. We report on a 29-year-old woman who was obese, para 0, and diagnosed with cervical insufficiency at the first trimester of current pregnancy due to a previous trachelectomy. She underwent laparoscopic transabdominal cervical cerclage (LTCC for cervical cancer. The surgery was successful and she was discharged two days later. The patient underwent a caesarean section at 38 weeks of gestation. Laparoscopic surgery is a minimally invasive approach associated with less pain and faster recovery, feasible even in obese women.

    Forty-three patients operated for cervical myelopathy were examined with a 1.5 T magnetic resonance imaging. Cord compression was demonstrated directly on the sagittal image in cases of cervical disc herniation, cervical spondylosis and O.P. L.L. Herniated disc material was seen positive on axial image. But factors of cord compression in cases of cervical spondylosis and O.P. L.L. were not clearly confirmed, so additional examinations such as myelogram, tomogram and CT was needed. (author).

    Full Text Available In case of invasive cervical carcinoma several molecular events were reported and these molecular events resulting in multiple genetic abnormalities. In order to control these tumors multiple molecular therapeutic targets are needed with different molecular mechanisms. Unfortunately, these molecular targets were in early stages of development. Because of less degree of success of conventional therapeutics for late stages of cervical cancer and lowering of prognosis of patients there is an increase in interest for the development of potential therapeutic targets for cervical cancer. This review article emphasizes the current molecular targeted agents; with special attention to estrogen receptors for human papilloma virus infected cervical cancer.

    Full Text Available Radiologist always examines X-ray to determine abnormal changes in cervical, lumbar & thoracic vertebrae. Osteophyte (bony growth may appear at the corners of vertebrae so that vertebral shape becomes abnormal. This paper presents the idea from Image processing techniques such as customised Hough transform which will be used for segmentation which should be independent of rotation, scale, noise & shape. This segmented image will be then used for computing size invariant, convex hull based features to differentiate normal cervical vertebrae from cervical vertebrae containing anterior osteophyte. This approach effectively finds anterior osteophytes in cervical vertebrae.

    2015-01-01

    We study the behavior of two dimensional supersymmetric connections of $n$ copies of $O(N)$ models with an $\\mathcal{N} = (0,1)$ heterotic deformation generated by a right moving fermion. We develop the model in analogy with the connected $\\mathcal{N}=(0,2)$ $CP(N-1)$ models for the case of a single connecting fermionic superfield. We calculate the effective potential in the large $N$ limit and determine the vacuum field configurations. Similarily to other SUSY connected models we find that SUSY is unbroken under certain conditions despite the vanishing of the Witten index. Specifically, this preservation of SUSY occurs when we have an even number $n$ of $O(N)$ families. As in previous cases we show that this result follows from a $Z_n$ symmetry under a particular exchange of the $O(N)$ families. This leads to a definition of a modified Witten index, which gaurantees the preservation of SUSY in this case.

    To evaluate the outcomes and feasibility of stereotactic body radiotherapy (SBRT) for cT3 and cT4N0M0 non-small cell lung cancer (NSCLC), 25 patients with localized primary NSCLC diagnosed as cT3 or cT4N0M0, given SBRT between May 2005 and July 2013, were analyzed. All patients had inoperable tumors. The major reasons for tumors being unresectable were insufficient respiratory function for curative resection, advanced age (>80 years old) or technically inoperable due to invasion into critical organs. The median patient age was 79 years (range; 60-86). The median follow-up duration was 25 months (range: 5-100 months). The 2-year overall survival rates for T3 and T4 were 57% and 69%, respectively. The 2-year local control rates for T3 and T4 were 91% and 68%, respectively. As for toxicities, Grade 0-1, Grade 2 and Grade 3 radiation pneumonitis occurred in 23, 1 and 1 patient, respectively. No other acute or symptomatic late toxicities were reported. Thirteen patients who had no local, mediastinal or intrapulmonary progression at one year after SBRT underwent pulmonary function testing. The median variation in pre-SBRT and post-SBRT forced expiratory volume in 1 s (FEV1) values was -0.1 (-0.8-0.8). This variation was not statistically significant (P = 0.56). Forced vital capacity (FVC), vital capacity (VC), %VC and %FEV1 also showed no significant differences. SBRT for cT3 and cT4N0M0 NSCLC was both effective and feasible. Considering the favorable survival and low morbidity rate, SBRT is a potential treatment option for cT3 and cT4N0M0 NSCLC. PMID:26983978

    Introduction: Radical cystectomy is the standard treatment for muscle invasive bladder cancer. We assessed clinical outcomes in patients found to have no evidence of disease (i.e., pT0N0) following radical cystectomy. Methods: We collected and pooled a database of 2287 patients who underwent radical cystectomy between 1993 and 2008 in eight centres across Canada. Of this number, 135 patients were found to have pT0N0 bladder cancer at the time of cystectomy. Survival data and prognostic variables were analyzed using Kaplan-Meier method and Cox proportional hazard regression analysis. Results: Median patient age was 66 years with a mean follow-up of 42 months. Clinical stage distribution was Tis 8.9%, Ta 1.5%, T1 20.7%, T2 45.2%, T3 5.2%, and T4 5.2%. The five-year recurrence-free survival (RFS), disease-specific survival (DSS) and overall survival (OS) were 83%, 96%, and 88%, respectively. The 10-year RFS, DSS and OS were 66%, 92%, and 70%, respectively. On Cox proportional regression analysis, no variables were associated with disease recurrence and only patient age was associated with overall survival. Interpretation: Patients with pT0N0 pathology after cystectomy have excellent outcomes with high five- and 10-year RFS, DSS and OS. However, there is still a risk of tumour recurrence in this patient population and thus postoperative surveillance is still required. PMID:22709882

It is challenge for surgeon to assess its clinical behaviour and come to a final diagnosis. These diseases which can be neoplastic also demands correct diagnosis for further management. The study intends to find out systematically the various p athological conditions presenting with enlarged lymph nodes in the neck, also various modes of clinical presentation and behaviour of these conditions. Relevant investigations have also been studied. METHODS AND MATERIALS : The study population consisted of patients above 12 years presenting with cervical lymph node enlargement. The material consists of patients during the period of January 2011 to J uly 2012. This study consists of 100 consecutive cases. Diagnosis is made on the basis of histopathological fi ndings. Patient was examined systemically giving utmost importance to local examination. After making a clinical diagnosis, further relevant investigations were done to confirm the diagnosis. Treatment was instituted appropriately and followed up the patie nts. RESULTS : Majority of the cases in this study had non - neoplastic causes for cervical lymphadenopathy in which tuberculosis is most common. Male and female ratio of 1.38:1 is noted with most cases between 12 and 30 years. Posterior triangle group of lym ph nodes was most commonly affected in tuberculosis. In lymphomas level 2 group of among the groups of lesions, with regard to local characteristics like number, laterality , mobility and involvement of other group of lymph nodes etc .FNAC by virtue of it being inexpensive, quick in getting results and easy to perform , is one of the important and essential diagnostic procedures.

  1. Control of cervical node metastases from carcinoma of the oral tongue by preoperative irradiation

    International Nuclear Information System (INIS)

    A total of 48 patients with carcinoma of the oral tongue, who were treated with surgery after irradiation of the primary lesion and neck node were analyzed. Twenty-six of 33 patients with clinically negative nodes (N0 Group) and all 15 patients with clinically positive nodes (N1-2 Group) underwent neck dissection. Four patients (15%: 4/26) had occult node metastases. Three patients in the N0 Group (9%: 3/33) subsequently developed metastases to the neck after treatment. Incidence of cervical node metastases in the N0 Group was 21% (7/33). Of the six metastatic nodes in the N0 Group and the 36 metastatic nodes in the N1-2 Group, 14 with IIa, 15 with IIb, three with III and ten with IV ab and c histopathological change (Ohboshi-Shimozato's Classification) were found. The combination of preoperative irradiation and neck dissection for regional lymph nodes of the oral tongue was effective against occult and subsequent metastases. (author)

    detección oportuna de cáncer basados en citología, particularmente en países con altos y medianos ingresos. Sin embargo, en muchos países de bajos ingresos el programa de detección oportuna de cáncer basado en citología apenas está siendo implantado correctamente o tiene fallas, por lo que no se puede apreciar el alcance para reducir las tasas de este cáncer. El hecho es que la infección con ciertos tipos de virus de papiloma humano es ahora reconocida como una causa necesaria de la enfermedad, lo que ha conducido a nuevas investigaciones frente a la prevención del cáncer cervical. Las pruebas de ADN del virus del papiloma humano se han mostrado como una herramienta prometedora con gran sensibilidad, pero con especificidad más baja que la citología. En combinación con citología ginecológica, la prueba del virus del papiloma humano tiene potencial para mejorar el valor predictivo negativo de la prueba convencional, permitiendo incrementar los intervalos de periodicidad de la misma y poder disminuir los costos del programa con seguridad aceptable. Los avances en el procesamiento de la prueba de citología y automatización de pruebas que determinan ADN del virus, han permitido nuevas propuestas de tamizaje lo que incrementa cada vez más su aceptación en países de altos y medianos ingresos. Para países de bajos ingresos, se ha probado que la inspección visual con ácido acético es una alternativa efectiva para la citología convencional, especialmente observada en sitios en los que los programas de tamizaje no han sido organizados. Referente a la prevención primaria del cáncer cervical, investigaciones recientes sobre seguridad y eficacia de la vacuna profiláctica contra el virus del papiloma humano han mostrado resultados muy prometedores con una eficacia cercana a 100% en prevención de infecciones persistentes y desarrollo de lesiones precursoras de este cáncer.

  6. Sport injuries of the cervical spine

    International Nuclear Information System (INIS)

    The article reports on injuries of the cervical spine occurring during sports activities. An attempt is made to reconstruct the movements which led to the cervical spine injuries in question. In two cases of accidents occuring during bathing, one football accident and a toboggan accident, the injuries concerned point to hyperextension of the cervical spine as cause of the injury. In another football accident and a riding accident, the changes observed allow us to conclude that the movement leading to the injury must have been a hyperflexion. One accident occurring while jumping on the trampolin resulted in an injury of the upper cervical spine pointing to the action of a compressive force on the cervical spine in addition to the force resulting in hyperflexion.

    2012-02-01

    The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970\\'s. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

    2008-01-01

    Cervical arthroplasty after anterior decompression with insertion of a prosthetic total disc replacement has been suggested as an alternate to anterior cervical fusion. It develops quickly during recent years. Currently there are several cervical arthroplasty devices. Each device varies in terms of materials, range of motion and constraint. Early studies suggest that in the short term, the complication rate and efficacy is no worse than fusion surgery. Long-term results have not yet been reported. This review examines the current prostheses as well as discussing issues regarding indications and technique. It is hoped that an improvement of cervical arthroplasty occurs in terms of materials and design as spinal surgeons enter a new dines of the management of cervical spine disease.

    We describe three patients with misdiagnosed unstable fractures of the cervical spine, who were treated conservatively and developed kyphotic deformity, myelopathy, and radiculopathy. All three patients were then managed with closed reductions by crown halo traction, followed by instrumented fusions. Their neurologic function was regained without permanent disability in any patient. Unstable fractures of the cervical spine will progress to catastrophic neurologic injuries without surgical fixation. Posttraumatic kyphosis and the delayed reduction of partially healed fracture dislocations by preoperative traction are not well characterized in the subaxial cervical spine. The complete evaluation of any subaxial cervical spine fracture requires CT scanning to assess for bony fractures, and MRI to assess for ligamentous injury. This allows for assessment of the degree of instability and appropriate management. In patients with delayed posttraumatic cervical kyphosis, preoperative closed reduction provided adequate realignment, facilitating subsequent operative stabilization. PMID:26321304

    Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery. PMID:25239380

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

    Full Text Available Objective: The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy. Materials and Methods: We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015. Results: The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years. Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%. On control examinations, there was no finding of instability or cervical kyphosis. Conclusion: Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.

  16. Diagnosis of cervical disc disease

    International Nuclear Information System (INIS)

    High resolution CT easily localized lesions including soft tissues of the bone such as disc protrusion and thickening of the yellow ligament. In all cases, myelography demonstrated compression of the nerve roots of the spinal cord which corresponded to CT findings at the level where plain CT revealed a lesion. However, CT metrizamide myelography demonstrated the lesion more clearly than did conventional myelography. CT metrizamide myelography also outlined compression of the nerve roots satisfactorily and demonstrated compressed findings of the spinal cord in the dynamic study. Thus, high resolution CT was useful for screening of cervical disc disease, and CT metrizamide myelography, for identification of lesions of the nerve roots. (Chiba, N.)

    Objective:To measure the expression pattern ofSTAT2 in cervical cancer initiation and progression in tissue sections from patients with cervicitis, dysplasia, and cervical cancer. Methods:Antibody against humanSTAT2 was confirmed by plasmids transient transfection andWestern blot.Immunohistochemistry was used to detectSTAT2 expression in the cervical biopsies by using the confirmed antibody againstSTAT2 as the primary antibody.Results:It was found that the overall rate of positiveSTAT2 expression in the cervicitis, dysplasia and cervical cancer groups were38.5%,69.4% and76.9%, respectively.TheSTAT2 levels are significantly increased in premalignant dysplasia and cervical cancer, as compared to cervicitis(P<0.05). Noticeably,STAT2 signals were mainly found in the cytoplasm, implying thatSTAT2 was not biologically active.Conclusions:These findings reveal an association between cervical cancer progression and augmentedSTAT2 expression.In conclusion,STAT2 increase appears to be an early detectable cellular event in cervical cancer development.

    Cervical spinal cord injury is a rare but serious complication after general anesthesia. The risk factors include traumatic cervical injury, cervical spine instability, and difficult airway management. It has also occurred in the absence of cervical instability. Here we report a patient who had a history of intermittent neck pain without numbness. Preoperative radiologic examinations showed degenerative changes in the cervical spine. She developed progressive tingling and numbness in her limbs after thyroidectomy under general anesthesia. Magnetic resonance imaging showed a cervical disc protruding into the canal at C5-C6, which was considered to be induced by surgical positioning. She recovered after anterior cervical decompression and internal fixation surgery. PMID:23828450

    Genital infection with human papillomavirus (HPV) is decisive in the causation of cervical cancer. In order to evaluate the epidemiology of HPV infection in Ushuaia, Province of Tierra del Fuego, Argentina, 132 endocervical cytobrushes from preneoplastic and neoplastic cases and controls were studied. Detection and typing of the viral genome was performed by polymerase chain reaction, combined with a restriction fragment length polymorphism assay or hybridization. The overall prevalence of HPV infection was 41% in the population examined, with a frequency of 26% in the controls and 71% in the cases under study. The 14-24 age group showed the highest HPV prevalence. The most common viral types in the infected population were HPV 16 (23%), HPV 18 (11%), HPV 33 (8%) and HPV 35 (8%), while high risk viral types were detected in 30% of the samples, 16% of the controls and 60% of the cases. This study provides the first data on the predominant viral types in Ushuaia. Our results show lower levels of infection than in regions with a high incidence of cervical cancer, HPV 16 being the most prevalent viral type. This research may be useful for selecting a specific vaccine targeting the population examined. PMID:16784128

    Cervical treatment of oral maxillary squamous cell carcinoma (SCC) remains controversial. We determined the metastases incidence and evaluated its predictive factors. Systematic review and meta-analysis was conducted of 23 Chinese and English-language articles retrieved from PubMed, Ovid, Embase, Cochrane Library, China National Knowledge Infrastructure, and Chinese Scientific and Technological Journal databases. Total cervical metastases and occult metastases rate was 32% and 21%, respectively. Positive lymph node detection was likeliest from levels I to III. The maxillary gingival metastases rate was higher than that of the hard palate. Advanced-stage tumors had higher metastatic risk than early-stage tumors. Well-differentiated tumors had a significantly higher metastases rate than medium and poor-differentiation tumors. N0 cases had survival benefit compared with N+ cases. Metastases rate of oral maxillary SCC correlates significantly with T classification and pathological stage. T and N classifications impact outcome significantly. Therefore, levels I to III selective neck dissection is recommended for patients with T3/4 cN0 disease. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2335-E2342, 2016. PMID:26890607

    To find the determinant of lymph node (LN) manifestations on preoperative multidetector CT (MDCT) in early gastric cancer (EGC) patients with pN0. One hundred and eighty-six consecutive patients with pT1pN0, the largest perigastric LN on preoperative MDCT, were categorized into two groups according to 8 different parameters [short (SD) and long diameter (LD) 4/6/8 mm, average attenuation 100 Hounsfield unit, short-to-long diameter-ratio (SLR) 0.7], and correlated with the size, gross type, depth of invasion and microscopic type of their primary lesions by the chi-square test and multiple logistic regression analysis. When the primary lesion was larger than 3 cm, the LNs were larger in 4 parameters (SD or LD, 4/6 mm; p < 0.05); gross type IIb patients showed smaller LNs in 5 parameters (SD 4/6 mm, LD 4/6/8 mm; p < 0.05); and patients with microscopically-undifferentiated lesions showed larger LNs in SD 4 mm or LD 8 mm by the chi-square test and multiple logistic regression analysis. The depth of invasion showed no significant difference in LN size. No factors revealed significant difference in LN attenuation or SLR. Benign regional LN enlargement is more frequent in EGC patients with larger size primary lesions or lesion with poor microscopic differentiation. However, this condition is less frequent in gross type IIb patients.

    Here we report negative electron affinities of NO(2)(-).(H2O)n clusters (n=0-30) obtained from density functional theory calculations and a simple correction to Koopmans' theorem. The method relies on the calculation of the detachment energy of the monoanion and its highest occupied molecular orbital and lowest unoccupied molecular orbital energies, and explicit calculations on the dianion itself are avoided. A good agreement with resonances in the cross section for neutral production in electron scattering experiments is found for n=0, 1, and 2. We find several isomeric structures of NO(2)(-).(H2O)2 of similar energy that elucidate the interplay between water-water and ion-water interactions. The topology is predicted to influence the electron affinity by 0.5 and 0.4 eV for NO(2)(-).(H2O) and NO(2)(-).(H2O)2, respectively. The electron affinity of larger clusters is shown to follow a (n+delta)-1/3 dependence, where delta=3 represents the number of water molecules that in volume, could replace NO(2) (-). PMID:17461632

Chlo-rine photosensitizer Photolon was given intravenously at a dose of 0.75–1.15 mg/kg body weight. 2.5 h later the treatment with polyposition laser exposure (light dose – 150 J/cm2, light power density – 400–500 mW/cm2 was made. Thirty days later conization of the cervix with endocervical curettage assessing therapeutic response of cervical tumor tissue was per-formed. According to histological data complete response was in 4 patients, minute foci of CIN I were determined in 7 patients, 1 patient had foci of CIN II. 8 of 10 HPV-positive patients had complete eradication of HPV after treatment. There were no serious adverse events after light exposure. Marked therapeutic response, high anti-viral activity and good feasibility allow to consider photodynamic therapy as alternative organ-sparing treatment of early cancer and pre-cancer of cervix.

    2013-01-01

    Persistent infection with high-risk types of human papillomavirus(HPV) is known to cause cervical cancer; however,additional genetic and epigenetic alterations are required for progression from precancerous disease to invasive cancer.DNA methylation is an early and frequent molecular alteration in cervical carcinogenesis.In this review,we summarize DNA methylation within the HPV genome and human genome and identify its clinical implications.Methylation of the HPV long control region (LCR) and L1 gene is common during cervical carcinogenesis and increases with the severity of the cervical neoplasm.The L1 gene of HPV16 and HPV18 is consistently hypermethylated in invasive cervical cancers and can potentially be used as a clinical marker of cancer progression.Moreover,promoters of tumor suppressor genes (TSGs) involved in many cellular pathways are methylated in cervical precursors and invasive cancers.Some are associated with squamous cell carcinomas,and others are associated with adenocarcinomas.Identification of methylated TSGs in Pap smear could be an adjuvant test in cervical cancer screening for triage of women with high-risk HPV,atypical squamous cells of undetermined significance,or low grade squamous intraepithelial lesion (LSIL).However,consistent panels must be validated for this approach to be translated to the clinic.Furthermore,reversion of methylated TSGs using demethylating drugs may be an alternative anticancer treatment,but demethylating drugs without toxic carcinogenic and mutagenic properties must be identified and validated.

    2016-01-01

    The new German S3 guideline 'Prevention of Cervical Cancer' published in 2016 is based on the latest available evidence about cervical cancer screening and treatment of cervical precancer. Large randomized controlled trials indicate that human papillomavirus (HPV)-based screening may provide better protection against cervical cancer than cytology alone through improved detection of premalignant disease in the first screening round prior to progression. Therefore, women aged 30 years and older should preferably be screened with HPV testing every 3-5 years (cytology alone every 2 years is an acceptable alternative). Co-testing is not recommended. Screening should start at 25 years using cytology alone every 2 years. The preferred triage test after a positive HPV screening test is cytology. Women positive for HPV 16 and HPV 18 should receive immediate colposcopy. Another alternative triage method is p16/Ki-67 dual stain cytology. The mean yearly participation rate in Germany is between 45 and 50%. Offering devices for HPV self-sampling has the potential to increase participation rates in those women who are at higher risk of developing cervical cancer. Regarding primary prevention, the 9-valent vaccine may provide protection against up to 85% of cervical intraepithelial neoplasia (CIN) 3 and 90% of cervical cancer, and is available in Europe as a 2-dose schedule from May 2016.

    International Nuclear Information System (INIS)

    Background. Children with neurofibromatosis type 1 (NF1) are at increased risk of developing plexiform neurofibroma throughout the body, including the cervical soft tissues. However, the incidence of cervical soft tissue tumors and the value of screening MR for children with NF1 are not known. Purpose. The purposes of this study were to determine the incidence and clinical significance of cervical tumors seen on MR imaging in children with NF1. Materials and methods. A retrospective review of the brain and orbit MR with cervical images obtained on 95 children who meet the NIH consensus criteria for NF1 and who are followed at our neurofibromatosis clinic was carried out. Results. Cervical tumors were found on MR imaging in 21 of 95 (22 %) children. Of 21 children with cervical tumors, 14 children were determined to be surgical candidates. In nine children, MR imaging altered the clinical management by demonstrating tumors for which surgery was indicated, but the tumors were not suspected prior to MR imaging. Conclusion. Cervical tumors are commonly seen in children with NF1. MR imaging may demonstrate a significant number of tumors that require surgery, but were not suspected prior to MR imaging. (orig.)

    Cervical vertigo refers to a syndrome with a chief complaint of vertigo arising from cervical verteprae discomfort. In general, cervical vertigo is correlated with but not always caused by cervical spondylopathy,which mainly includes vertebral arterial and sympathetic cervical spondylosis.

    Full Text Available Introduction. Spontaneous dissection of the cervical artery is a rare non-atherosclerotic vascular disease of unknown aetiology and unclear pathogenesis that may be a cause of ischemic stroke in young adults. Diagnosis. Precise diagnosis of dissection of the cervical artery - carotid or vertebral - is possible with cervical axial magnetic resonance imaging and magnetic resonance angiography. Treatment. The recommended treatment in the acute phase of cervical artery dissection is anticoagulant or antithrombotic therapy, aimed at preventing a primary or recurrent ischemic event. There have been as yet no results of randomized controlled studies comparing efficacy of both treatments. An ongoing randomized multicentre study is expected to provide answers about the effects of these treatments in cervical artery dissection. Outcome. Complete resolution of arterial abnormalities is achieved in around 46% of stenoses, 33% of occlusions, and 12% of dissecting aneurysms. Recurrent events. Recurrence of cerebral ischemia and cervical artery dissection seems to be rare, although some data suggest that early ischemic and late cervical artery dissection recurrences could be underestimated. Mortality and functional outcome. In comparison with other causes of stroke in young adults, the functional outcome of cervical artery dissection is good in contrast to its socio-professional effects, which may be unsatisfactory. The mortality rate of cervical artery dissection is low, although it may be underestimated since some patients with malignant infarction die before the diagnosis is established. Conclusion. Further research is warranted to improve our understanding of the underlying pathophysiology, to assess the long-term outcome, and ultimately to provide treatment and prevention strategies.

  18. Radiological evaluation of the cervical spinal trauma

    International Nuclear Information System (INIS)

    Acute injuries of the cervical spine are the most common causes of severe disability following trauma, yet the diagnosis of these injuries are often delayed and the treatment, inadequate. Traumatic injuries of the cervical spine are diagnosed by radiological examinations. And complete evaluations of bony structures and soft tissue changes on conventional radiograms are very important for determining the therapeutic plans and prognoses of the injuries patients. During the period of 5 years from June 1976 to May 1981, the radiological and clinical evaluation had been made on 38 patients suffered from acute cervical spinal injuries which were confirmed by the radiological examinations. The results were as follows. 1. Age distribution of total 38 patients was broad ranging from 19 years to 72 years. 2. The most common cause of injury was traffic accident, next fall down, other accident respectively. 3. Levels of the cervical spinal injuries were as follows: Upper cervical spine in 15.8%, lower cervical spine in 84.2%, and the most common injuries level was C 5. Most of the lower cervical spinal injuries were located in the vertebral body and spinous process. 4. Anatomical sites of the cervical spinal injuries were as follows; vertebral body in 55.5%, spinous process in 23.7%, neural arch in 15.8%, and locked facet in 18.4%, etc. 5. Most of the patients with severe mental changes were injuries in upper cervical spine rather than lower. And most of the patients with quadriplegia or paraplegia were shown marked disruption of spinal canal

    Full Text Available Cervical cancers form the second highest number of female cancers in Malaysia, imposing a substantial amount of cost burden on its management. However, an estimation of cost burden of abnormal smears, cervical pre-invasive and invasive diseases needs to be done to show how much spending has been allocated to the problem. An expert panel committee came up with the clinical pathway and management algorithm of  cervical pre invasive and invasive diseases from July-December 2006 Malaysia. An activity based costing for each clinical pathway was done. Results were converted to USD. The cost of managing pre-invasive cervical cancers stage is USD 420,150 (Range: USD 197,158-879,679. Management of invasive cancer (new cases costs USD 51,533,233.44 (Range: USD 32,405,399.69 - USD 129,014,768.40. The cost of managing existing cases is USD 17,005,966.87 (Range: USD 10,693,781.90 - USD  28,901,587.12. The total cost of managing cervical cancers by health care providers in a public setting is around USD 75,888,329.45 (Range: USD 48,083,804.60 - USD 48,083,804.60. The outcome of this study has shown that preventive modalities such as screening have only contributed to 10.3 % of the total management cost of cervical cancer. The major cost contribution (67% came from treatment of invasive cancer especially at more advanced stages of cancer, followed by treatment of existing cases (22% and lastly on pre-invasive disease (0.6%. This study revealed that proportion of preventive modality in this country was still low, and the major cost came from actual treatment cost of cervical cancer. Therefore, heightened public cervical cancer screening in the country is needed. (Med J Indones 2008; 17: 272-80Keywords: cervical cancers, pre invasive disease, HPV vaccination

    2014-12-01

    Full Text Available Background: Cervical radiculopathy is a dysfunction of nerve root of the cervical spine where C6& C7 nerve roots are the most commonly affected. It encompasses important symptoms other than pain, such as paresthesia, numbness and muscle weakness in dermatomal or myotomal distribution of an affected nerve root. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy, including mechanical cervical traction, manipulation, therapeutic exercises and TENS. Studies to find out the effectiveness of TENS versus Intermittent Cervical Traction among patients with Cervical Radiculopathy are sparse. Hence the present study was undertaken to find out and compare effectiveness of TENS versus Intermittent Cervical Traction a newer technique towards betterment in treatment of cervical radiculopathy patients. Methodology: 30 patients from Baroda association for the blind (Lions club of Baroda, Subhanpura & Sushrut Physiotherapy Clinic, Akota were chosen based on the inclusion and exclusion criteria. Group A comprised of 15 people with cervical radiculopathy were given TENS with Isometric neck exercises and active neck movements. Group B comprised of 15 people with cervical radiculopathy were given Intermittent Cervical Traction with Isometric neck exercise and active neck movements. VAS Scale & Neck Disability Index (NDI were used as outcome measures pre & post treatment. Results: The pre test evaluation showed that, there is no significant difference (P> 0.05 between the two groups for all the variables measured. The post-test evaluation of both groups showed a very high significance (P< 0.05 within the group for all the outcome measurements. A post-test comparison of measured variables, between the groups showed that the Group A demonstrated a statistically significant (P< 0.05 reduction in pain and Neck Disability Index. Conclusion: From the above study concluded that TENS was more effective

    The main methods of treatment for cervical cancer are surgery, radiotherapy or their combination. During past two decades chemotherapy are increasingly being used not only in patients with disseminated forms of this disease but also in patients undergoing chemoradiotherapy or as induction therapy. Possibilities of adjuvant chemotherapy for cervical cancer are being studied. According to A.D.Kaprin and V.V. Starinskiy in 2013 in Russia, 32% of patients with newly diagnosed cervical cancer underwent only radiation therapy, 32%--combined or complex treatment, 27.3%--only surgery, and just 8.7%--chemoradiotherapy.

    International Nuclear Information System (INIS)

    A retrospectivce analysis of pediatric admissions over 10 years revealed 29 patients with cervical spine injuries. Eleven patients were below 12 years of age, and 10 of these had injuries involving C1, C2 or the occipitoatlantal articulation. Eighteen patients were between 12 and 16 years of age with injuries distributed throughout the cervical spine similar to injuries in the adult population. Our results suggest that teenagers with suspected cervical injuries are best evaluated by an adult radiographic series including trauma oblique views. In younger patients, careful evaluation of occipitoatlantoaxial alignment and the prevertebral soft tissues is required for diagnosis and selection of additional imaging evaluation. (orig.)

    The project was divided in two well-differentiated parts: SO{sub 2} removal and NO{sub x} reduction. In both cases, carbon materials play a unique role in the processes, either as calcium sorbent support (SO{sub 2} removal) or as catalyst support and reducing agent (NO{sub x} reduction). Removal of SO{sub 2}. This process was carried out by calcium sorbents at relatively low temperature (T<300 degree centigree), forming CaSO{sub 3} (instead of CaSO{sub 4}) that decomposes at lower temperatures, making regeneration easier. High dispersion of the active species, CaO, has been obtained using carbon materials (activated carbons, chars, etc) and other inorganic compounds as supports. The effect of oxygen, carbon dioxide and steam in the reaction atmosphere and the regeneration process have been also investigated. Thermal regeneration is possible for several cycles, however, carbon gasification also takes place. To control, and to void that effect the reaction and regeneration temperatures should be carefully controlled and carbons with low reactivity should be selected. The process was scaled (100-2000) using briquette samples obtained by physical mixture of char and Ca(OH){sub 2}. The SO{sub 2} removal levels were similar to those found in the laboratory scale. NO{sub x} reduction. The possibility of using potassium containing coal-briquettes for NO and NO{sub x} reduction has been investigated. The preparation method of briquettes presents the advantage of using a binder agent (humic acid) which contains the catalyst (potassium). The system catalyst-binder-coal stays intimately joined by a moulding stage and subsequent pyrolysis, providing proper mechanical resistance to the coal-briquettes. With the purpose to improve the briquettes activity, different variables of the preparation process have been investigated (potassium content-added with the binder and/or KOH-. rank and mineral matter content of the coal precursor, pyrolysis temperature and pressure of the moulding stage). Potassium containing briquettes exhibit a considerable capacity for NO{sub x} reduction and, interestingly, are quite selective towards NO{sub x} reduction against oxygen gasification. This behaviour is very important, taking into account that one of the main disadvantages of carbonaceous materials in NO{sub x} pollution control is the great consumption of carbon due to oxygen combustion.

    We present the case of a 44-year-old man who complained of cervical pain. He was treated with physiotherapy and analgetics. Because of persistent pain, computed tomography (CT) scan and MRI were performed. They revealed an osteolytic destruction of the fourth cervical vertebra. The patient was treated surgically for removal of the tumor and stabilization of his cervical spine. Histology of the osteolytic material led to the diagnosis of an eosinophilic granuloma of the cervical spine. This case report describes the incidence, clinical significance, background and therapy of an eosinophilic granuloma of the spine. PMID:15120180

  14. Distracted cervical spinal fusion for management of caudal cervical spondylomyelopathy in large-breed dogs

    International Nuclear Information System (INIS)

    Using an autogenous bone graft (obtained from the iliac crest), 4-mm cancellous bone screws, and polymethylmethacrylate, a distracted cervical spinal fusion technique was performed on 10 dogs with myelographic evidence of caudal cervical spondylomyelopathy. All dogs had evidence of dynamic soft tissue spinal cord compression, as indicated by flexion, extension, and traction myelographic views. Of the 10 dogs, 4 previously had undergone surgery by use of ventral slot or cervical disk fenestration techniques, and their neurologic status had deteriorated after the original surgery. Preoperative neurologic status of the 10 dogs included nonambulatory tetraparesis (n = 5), severe ataxia with conscious proprioceptive deficits (n = 2), and mild ambulatory ataxia with conscious proprioceptive deficits (n = 3). Five dogs had signs of various degrees of cervical pain. Clinical improvement was observed in 8 of 10 dogs--either improved neurologic status or elimination of cervical pain. Implant loosening developed in 3 dogs; 2 of them were euthanatized because of lack of neurologic improvement. Radiographic evidence of bony cervical fusion was observed during a 9- to 24-week period in 6 of the 8 surviving dogs. The distracted cervical fusion technique appears to be a valid surgical procedure to manage cervical spondylomyelopathy in those dogs in which the lesions are limited to one cervical intervertebral disk space

    The mixed Si{sub 10-n}N{sub n} (n=0-10) clusters have been investigated systematically using Amsterdam Density Functional (ADF) program with TZ2P basis set in conjunction with self-consistent field (SCF). For the silicon-nitrogen binary cluster system, Si-rich clusters favor three-dimensional structures. The nitrogen atoms separate from each other, if possible. Near the n=5 stoichiometry, the lowest energy structures are highly stable like-planar structures. They feature a strong alternation of Si and N atoms. For N-rich clusters, the forming N dimers are observed in the most stable structures. But, the N dimers are easy to be removed from the N-rich clusters. The remaining parts become linear or planar structures.

    In the context of the early recognition of cervical cancer the cytology has to detect tumor positive cases among a bulk of un suspicious specimens. Unfortunately there is a group of cases with a vague diaxosis, the so called PAP-ill-group. There are many reasons for the recent impossibility of a safe conclusion from the PAP-Ill-smears to their histological diagnoses (Pig. 1). Today for an exact statement a cone biopsy and a microscopical investigation of its histological sections for such caseS are necessary. That results in a high medical and economical expense and, last not least, that means a higher risk of complications and of future family planning problems for the women affected.

    Upper cervical vertebral has complex anatomic structure and some diseases may involve this vital center area of human body. Most of the diseases, such as trauma, malformation, and degeneration, need to be treated with surgery to recover the function of cervical vertebral. The accurate evaluation is crucial before and after the surgery. In the past few years, CT, MRI, and ultra-sound play important roles in the evaluation of upper cervical vertebral diseases and planning treatment. Comprehensive evaluation with multidisciplinary approach is advocated. In this paper we reviewed the anatomy and clinic treatments; summarized the latest imaging advances in upper cervical vertebral disease; discussed the perspective of comprehensive evaluation with multidisciplinary approach.

    Five horses, weighing 337 to 400 kg, were used in this research, one of them being used as control. Cervical myelography with iohexol (Omnipaque) was performed on four horses tranquilized with flunitrazepan before induction of anesthesia with sodium thiopental. Anesthesia was maintained with fluothane and oxygen. Cerebrospinal fluid (CSF) was analysed before and after an injection of ioxheol into the subarachnoid space. The animals received 25 to 50 ml of iohexol, after removal of 20 ml cerebrospinal fluid. Radiographies were taken with the horses at lateral recumbency, and the cranial, central and caudal regions of the cervical spine being focalized. No significant changes occurred in the cerebrospinal fluid after injecting the contrast medium. Pathologic changes were not found by gross or microscopic examination of the brain and the cervical spinal cord. Radiographies of good to excellent image quality were obtained. At autopsy, radiographic diagnosis of cervical vertebral instability was confirmed in the animal that had pelvic limb ataxia

    Full Text Available An 8-month-old male infant had presented with a history of a fall from the crib a fortnight ago. He had developed progressive weakness of both lower limbs. On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

  6. Radiosensitizers in cervical cancer. Cisplatin and beyond

    International Nuclear Information System (INIS)

    Cervical cancer continues to be a significant health burden worldwide. Globally, the majority of cancers are locally advanced at diagnosis; hence, radiation remains the most frequently used therapeutical modality. Currently, the value of adding cisplatin or cisplatin-based chemotherapy to radiation for treatment of locally advanced cervical cancer is strongly supported by randomized studies and meta-analyses. Nevertheless, despite these significant achievements, therapeutic results are far from optimal; thus, novel therapies need to be assayed. A strategy currently being investigated is the use of newer radiosensitizers alone or in combination with platinum compounds. In the present work, we present preclinical information on known and newer cytotoxic agents as radiosensitizers on cervical cancer models, as well as the clinical information emanating from early phase trials that incorporate them to the cervical cancer management. In addition, we present the perspectives on the combined approach of radiation therapy and molecular target-based drugs with proven radiosensitizing capacity

    BACKGROUND: Due to its extraordinarily fast economic and social transition, virtually closed borders before 1940 and, moreover, that 85% of the population has the distinctive genetics of the Inuit, Greenland is a very interesting country to study cervical cancer from a historical perspective....... Nevertheless, little has been reported about long-term cancer trends in Greenland. Our aim was to describe and interpret the incidence of cervical cancer from 1950 to 2009. MATERIAL AND METHODS: We systematically searched PubMed for articles reporting the incidence of cervical cancer in Greenland. We...... supplemented this with data for 1980-2009 obtained from the Chief Medical Officer of Greenland. RESULTS: Incidence of cervical cancer was around 10 per 100 000 women (age-standardised, world population, ASW) in the 1950s, 30 per 100 000 in the 1960s, and in the 1980s around 60 per 100 000.

    Full Text Available Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO′M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI and the Centre for Epidemiologic Studies Depression questionnaire (CES-D. Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64. Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision.

    2008-01-01

    Full Text Available Abstract Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

    Full Text Available The HPV types that cause cervical cancer are sexually transmitted, but there is little evidence that infection can be avoided by behavioural changes, such as condom use. In contrast, prophylactic vaccines against HPV infection are likely to have high efficacy. In principle, the effectiveness of HPV vaccination as a strategy for cervical cancer control can be measured either by monitoring secular trends in cervical cancer incidence or by conducting randomized trials. The former approach is unlikely to provide convincing evidence of effectiveness, since cervical cancer rates are subject to strong secular trends that are independent of intervention measures. A few phase III trials of HPV prophylactic vaccines are now being started. Such trials are very expensive studies involving frequent and complicated investigations. It is important, however, to start as soon as possible simpler trials designed to demonstrate the effectiveness of HPV vaccine in field conditions, i.e. in developing or intermediate countries which suffer the major burden of mortality from cervical cancer. Such trials may capture a difference in the most severe, and rarest, preinvasive cervical lesions (i.e., the real target of any HPV vaccine over a prolonged follow-up (20 years at least. The design of such studies is briefly considered for two areas: Southern India and South Korea.Los tipos de virus de papiloma humano (VPH que causan cáncer cervical son sexualmente transmisibles, pero existe muy poca evidencia sobre que la infección pueda ser evitada por cambios en las conductas sexuales de alto riesgo, tales como el uso del condón.

    Cervical cancer is the second most common cause of cancer death in women worldwide and the development of new diagnosis, prognostic, and treatment strategies merits special attention. Although surgery and chemoradiotherapy can cure 80%-95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

    Anterior cervical hypertrichosis is a very rare form of primary localized hypertrichosis. It consists of a tuft of terminal hair on the anterior neck just above the laryngeal prominence. The etiology is still unknown. In this article, we reported a 15-year-old female patient who presented to our clinic with a complaint of hypertrichosis on the anterior aspect of the neck for the last five years. Her past medical history revealed no pathology except for vesicoureteral reflux. On the basis of clinical presentation, our patient was diagnosed with anterior cervical hypertrichosis and she was considered to be a sporadic case due to lack of other similar cases in familial history. To date, 33 patients with anterior cervical hypertrichosis have been reported. Anterior cervical hypertrichosis can be associated with other abnormalities, but it frequently presents as an isolated defect (70%). The association of vesicoureteral reflux and anterior cervical hypertrichosis which was observed in our patient might be coincidental. So far, no case of anterior cervical hypertrichosis associated with vesicoureteral reflux has been reported in the literature. PMID:27103865

    2012-01-01

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

    Background A considerable number of patients with cervical spondylosis complain about one or multiple atypical symptoms such as vertigo, palpitations, headache, blurred vision, hypomnesia, and/or nausea. It remains unclear whether surgical intervention for cervical spondylosis can also effectively alleviate those symptoms. The current study was performed to see if anterior cervical diskectomy and fusion (ACDF) offers such an extra benefit for patients with cervical spondylosis. Objective To investigate if patients who received ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy can also achieve alleviation of certain atypical symptoms associated with cervical spondylosis after the surgery in the long run. Methods Sixty-seven patients who underwent ACDF for the treatment of cervical spondylotic myelopathy and/or radiculopathy were involved in this study. All these patients also complained about various associated atypical symptoms. They were followed up for 26 to 145 months after the surgery. Severity and frequency scores of the atypical symptoms before the surgery and at last follow-up were compared by paired t tests. Results Most patients reported significantly alleviated symptoms at the last follow-up compared with before the surgery. The severity of vertigo, headache, nausea, and palpitations were significantly alleviated at the last follow-up (with p values of p cervical spondylotic myelopathy and/or radiculopathy, but it is not effective in alleviating symptoms such as tinnitus, blurred vision, and hypomnesia. It can be considered for alleviating atypical symptoms when other treatment options prove ineffective. PMID:27168319

  1. Therapeutic outcomes of papillary thyroid carcinomas with tumors more advanced than T1N0M0

    International Nuclear Information System (INIS)

    Purpose: This retrospective study analyzed the role of total or near-total thyroidectomy and adjuvant radioactive iodide (131I) therapy in papillary thyroid carcinoma patients with disease more advanced than T1N0M0. Methods: The study analyzed 1055 consecutive papillary thyroid cancer patients, 825 women and 230 men, who underwent near-total or total thyroidectomy, thyroid remnant ablation with 131I, and follow-up at Chang Gung Medical Center in Linkou, Taiwan. Patients with T1N0M0 stage tumors were excluded. Patients were categorized into four groups according to treatment outcome. Group A was disease-free patients with negative results of 131I whole body scan, undetected serum thyroglobulin (Tg) and Tg antibody, and no recurrence. Group B patients had no clinical evidence of persistent or recurrent thyroid cancer but were not in disease-free status. Group C were patients with cancer tissue persisting after surgery. Group D were patients suffering cancer recurrence after surgery and 131I ablation. Results: After a mean follow-up period of 10.1 ± 5.4 years (median: 9.5 years), 46 (4.36%) patients died of thyroid cancer. Nine Group A cases with persistent or recurrent cancer were treated until achieving disease-free status. Group C patients received the highest 131I dose but had a 25.7% mortality rate. In Group D, the mean duration from first thyroidectomy to recurrence was 5.1 ± 0.4 years and ranged from 0.8 to 18.7 years. Four of 56 (7.1%) patients with recurrent local neck cancer died of thyroid cancer and 12 (21.4%) died of thyroid cancer with distant metastases. Conclusions: Radioactive iodide therapy effectively controlled papillary thyroid carcinoma after neck surgery in 23.9% of patients. After surgery and 131I treatments, most patients with persistent or recurrent local-regional neck cancer were free of relapse; the cancer mortality rate was 19.0%

    Full Text Available Worldwide, cervical cancer is the third most common cancer in women, and the first or second most common in developing countries. Cervical cancer remains in Colombia the first cause of cancer mortality and the second cause of cancer incidence among women, despite the existence of screening programs during the last 3 decades. Bucaramanga, Manizales and Cali reported rates around 20 per 100,000 and Pasto 27 per 100,000. The Cali cancer registry has reported a progressive decrease in the age standardized incidence and mortality rates of cervical cancer over the past 40 years. Reasons for the decline in incidence and mortality of cervical cancer are multiple and probably include: improvement in socio-economic conditions, decrease in parity rates and some effect of screening programs.Human papilloma Virus is the main cause of cervical cancer, HPV natural history studies have now revealed that HPVs are the commonest of the sexually transmitted infec¬tions in most populations. Most HPV exposures result in sponta¬neous clearance without clinical manifestations and only a small fraction of the infected persons, known as chronic or persistent carriers, will retain the virus and progress to precancerous and cancer. HPV 16 and 18 account for 70% of cervical cancer and the 8 most common types. (HPV 16, 18, 45, 33, 31, 52, 58 and 35 account for about 90% of cervical cancer. Case-control studies also allowed the identification of the following cofactors that acting together with HPV increase the risk of progression from HPV persistent infection to cervical cancer: tobacco, high parity, long term use of oral contraceptives and past infections with herpes simplex type 2 and Chlamydia trachomatis. The demonstration that infection with certain types of human papillomavirus (HPV is not only the main cause but also a necessary cause of cervical cancer has led to great advances in the prevention of this disease on two fronts: (i Primary prevention by the use of

    We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance ({rho} > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury.

    A prospective randomized study to determine the effect of radiation field on the local control of early glottic cancer was performed. From May 1982 through December 1985, a total of 87 patients with early glottic cancer (T1N0M0) were treated at our department with an individualized wedge filter technique using a shell to improve the dose distribution and immobilization during radiotherapy with 4 MV X ray. Patients were randomly allocated to either treatment group A (radiation field size: 5 x 5 cm2) or B (6 x 6 cm2) using bilateral parallel opposed portals. Total radiation dose administered was 60 Gy in 30 fractions over a 6-week period. The 3-year recurrence-free survival rates were 93% in group A and 96% in group B (no significant difference). Comparison with historical control showed that both arms achieved better results. These results were mainly due to the improved local control of whole-length lesions of single vocal cords. Acute mucosal reaction (p less than 0.05) and persistent arytenoid edema lasting more than 6 months (p less than 0.02) were more frequently observed in group B than in group A. It is concluded that the critical factor in getting optimal results in the treatment of early glottic cancer is careful attention to the technique of treatment.

  11. T3N0 glottic carcinoma: DNA S-phase as a predictor of the outcome after radiotherapy

    International Nuclear Information System (INIS)

    In consecutive series of 326 laryngeal cancer patients, of 29 with stage T3N0 glottic carcinomas, 23 achieved complete local remission after curative radiotherapy and form the basis of the present investigation. Flow cytometry determinations of DNA-ploidy status and the S-phase fraction, and a 'histopathological malignancy grading system' were evaluated as possible patients- and/or tumor-related predictors of local recurrence. Twelve patients were continuously disease-free after radiotherapy, whereas 10 manifested local recurrence, and one distant metastasis. The radiotherapy delivered to patients who later suffered from a local recurrence did not differ from those being continuously disease-free. The frequency of local recurrence was significantly correlated to patients whose primary tumors manifested a low S-phase fraction. A low S-phase fraction may indicate slowly proliferating tumour-cells, which become more radioresistant on exposure to a series of fractionated doses, as their reassortment into sensitive phases will be proportionately slower

    In the evaluation of biological potentials of contraceptives in the genesis of cervical cancer, cytology seems to have been given due attention while information on the clinical condition and specific treatment of the target organ, the cervix, is repeatedly neglected. "Cancer does not develop in a healthy cervix" is an old dogma derived from impressions gained by clinical examination of the organ. This concept is supported by epidemiologic studies indicating that cancer is extremely rare in cervices restored to a normal condition by cauterization. It may be postulated that this type of treatment destroys the permissive target cells of the cervix, thus indirectly rendering possible coitus-associated and contraceptive-associated(?) mutagen(s) invalid. Also, in comparative studies, an evaluation should be made of the significance of a higher incidence of cervical ectopy reported in women receiving oral hormonal contraceptives. The importance of ectopy in the genesis of cervical malignancy has been derived from the presumption that permissive cervical cells are thus created and exposed to vaginal contents which may harbor the mutagens(s). Therefore, it would seem not only desirable but imperative to include the neglected parameters of clinical condition and of specific treatment (both past and present) of the uterine cervix in the structure of studies like the recent one in this Journal on "Contraceptive choice and cervical cytology", by Drs. Shulman and Merritt. Still another parameter which might prove to be of significance is the predominant type of vaginal flora, which can be assessed readily in the routine examination of Papanicolaou smears. It may be that vaginal contents, which would seem to be somewhat different in wearers of the intrauterine contraceptive device as compared to "pill" users, might play a part in the advent of cervical malignancy as a medium of or for coitus-associated mutagens(s).

Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.Keywords: Cervical cancer, clinical trials, gene therapy, HPV E6 and E7 oncogenes, siRNAs

  15. N-staging of oesophageal and junctional carcinoma: Is there still a role for EUS in patients staged N0 at PET/CT?

    International Nuclear Information System (INIS)

    Aim: To assess whether separate endoscopic ultrasound (EUS) lymph node (N)-staging is still of prognostic value in those staged node negative (N0) at combined positron-emission tomography/computed tomography (PET/CT) in patients with oesophageal cancer (OC). Materials and methods: One hundred and seventeen consecutive patients [median age 67 years; 88 male; 98 cases of adenocarcinoma, 19 cases of squamous cell carcinoma (SCC)] staged as N0 at PET/CT underwent EUS to record tumour (T)- and N-stage. The patients were subsequently separated into two groups: EUS N0 (n = 78) and EUS N+ (n = 39). Survival analysis using Kaplan–Meier and Cox's proportional hazard methods was performed. Primary outcome was overall survival from diagnosis. Results: EUS N-stage and EUS N0 versus EUS N+ (p = 0.005 and p = 0.001, respectively) were found to be significantly and independently associated with survival in two models of multivariate analysis, in patients staged N0 at PET/CT. EUS T-stage was significantly associated with survival on univariate analysis. Conclusion: EUS N-staging still has prognostic value in patients staged N0 at PET/CT. There is a significant difference in survival between EUS N0 and positive nodal EUS status in those staged N0 at PET/CT, suggesting PET/CT is unreliable for local staging. PET/CT and EUS continue to have complimentary roles in OC staging. - Highlights: • PET/CT is being increasingly utilised for staging oesophageal cancer. • PET/CT has been shown to have similar diagnostic accuracy to EUS for local staging. • In patients staged N0 on PET/CT, EUS N-stage is an independent predictor of survival. • EUS N+ patients have poorer survival than EUS N0, in those staged PET/CT N0. • EUS and PET/CT should continue to be used in a multi-modality approach to staging OC

    Full Text Available Abstract Background The female lower genital tract is a gateway for pathogens entering the host through the mucous membrane. One of the prevalent human viruses is Torque teno virus (TTV. The major reported routes of TTV transmission are fecal-oral and parenteral. Furthermore, other modes of transmission, e.g. sexual contact, are suggested. To investigate the sexual route of TTV transmission, cervical smears of healthy women and those with cervical lesions were screened for the presence of TTV DNA. Methods TTV DNA was studied in cervical smears of 95 patients with cervical lesions and 55 healthy women. Paired serum samples were available from 55 and 42 women, respectively. All healthy women had normal cytology while 44 patients had histologically confirmed low-grade lesion (LGL and 51 high-grade lesion (HGL. TTV DNA was detected with primers specific for the non-coding region. In 40 paired cervical smears and serum samples, the phylogenetic group of TTV isolates was determined. The presence of HPV DNA in cervical smears was detected by means of PCR with MY09/11 primers. Results The prevalence of TTV DNA in cervical smears of healthy women was 52.7% and was comparable with that in paired serum samples (50%. Symptomatic women had significantly higher prevalence of TTV DNA in cervical smears (74.7% than healthy controls. The TTV DNA prevalence in patient serum samples was 51%. The phylogenetic groups of TTV serum isolates were concordant with those of TTV from cervical smears of the same subjects. In cervical smears, a wider variety of TTV isolates was found. The viral loads in cervical smears were 10 to 1000 times as high as in sera. The HPV-positive study subjects had significantly higher TTV DNA prevalence than HPV negatives. The prevalence of TTV was not associated with disease severity. Conclusion High prevalence of TTV in cervical smears suggests that sexual transmission is another mode of expansion of TTV infection among the population. The

    The case of a one-month-old patient admitted to the Department of Pediatrics (Medical and Health Science Center, Debrecen University) because of respiratory distress caused by a cervical mass compressing the upper respiratory pathways is presented. The mass could only be partially removed, the histological diagnosis proved to be neuroblastoma (SBCT: "small blue cell tumor"). Despite the fact that the DNA index of tumor cells (ploidy measurements) and the age of the patient suggested a favourable prognosis, the tumor continued to grow and metastases appeared. Because of symptoms of compression exerted on the respiratory system by the tumor, chemotherapy had to be applied. Since a standard OPEC/OJEC chemotherapeutic protocol proved to be not entirely effective and a residual tumor was still present, retinoic acid and interferon treatment was introduced. Presently, 4 years after the diagnosis, the patient is in complete remission and can be considered to be cured. The case presented here demonstrates that despite the favorable prognosis of the majority of infant neuroblastomas, in some cases the anatomic location of the tumor, leading to disturbance of vital functions, may serve as indication of chemotherapy. Our experience also proved the efficacy of retinoic acid and interferon treatment in relapsed neuroblastoma. PMID:15105902

    Several different physics procedures have been tried to mechanize the recording of partograms. Can a measure of impedance of tissue Z using potential difference V, according to Ohm's law V = Z1, and 1 is a constant, be correlated with a measure of cervical dilatation using vaginal examination? This was our hypothesis. The tissue impedance meter was made to our design and applied according to a bipolar procedure. Our work was carried out on 28 patients. 10 patients were registered before labour started in order to test the apparatus and to record the impedance variations without labour taking place, and 18 patients were registered in labour to see whether there was any correlation. The level of impedance in the cervix without labour was 302.7 Ohms with a deviation of 8.2. Using student's t tests it was found that there was a significant correlation (p less than 0.001) in four measurements between the impedance measure and measures obtained by extrapolating the degrees of dilatation calculated from vaginal examination. This is a preliminary study in which we have defined the conditions that are necessary to confirm these first results and to further develop the method. PMID:1401774

  13. Invasive cervical carcinoma (Stages IB-IIB)

    International Nuclear Information System (INIS)

    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    Full Text Available BACKGROUND AND OBJECTIVE: Cervical lymphadenopathy is the most common site of peripheral lymphadenopathy and is frequently encountered in otorhinolaryngology practice. Assessment and predicting its clinical behavior is not an easy task. Fine needle aspiration cytology (FNAC is being routin ely adopted as a special technique to diagnose the cause of lymphadenopathy. This study was undertaken to identify the clinic - demographic parameters in distribution of cases of cervical lymphadenopathy. FNAC was evaluated as a diagnostic tool by corroborat ing its results with histopathological examination of the excised lymph nodes. MATERIAL AND METHODS: This study was carried out at Hi - Tech Medical College and Hospital, Bhubaneswar, on 100 patients of cervical lymphadenopathy, over a period of two years. A long with detailed history, meticulous clinical examinations and investigations were performed. In all cases the diagnosis provided by FNAC and histopathology examination of the excised lymph node were correlated. RESULTS: Tuberculosis (45% was the most c ommon cause of cervical lymphadenopathy, followed by reactive (26% and metastatic secondaries (21% and lymphoma (8%. Maximum presentation was in 3 rd decade (22% and bilateral involvement was seen in 20% cases. Posterior triangle was the most common sit e involved (45%. Overall diagnostic accuracy of FNAC was 92%. CONCLUSION: Most common cause of cervical lymphadenopathy are tuberculosis, reactive lymphadenitis and metastatic secondaries. FNAC is a cheap, quick, readily available and dependable diagnostic modality and can be used as a first line investigatory tool in outdoor departments.

    Full Text Available Objective. We aim to investigate methods and use of cervical ripening in women without and with a prior cesarean delivery in The Netherlands. Methods. In 2010, we conducted a postal survey in all Dutch hospitals with a labor ward. One gynecologist per hospital was addressed and was asked to respond on behalf of the staff. The questionnaire contained 31 questions concerning cervical ripening and induction of labor. We compared this survey to a similar Dutch survey conducted in 2006. Results. Response rate was 78% (70/92 hospitals. In women without a prior cesarean and in need of cervical ripening, all hospitals (100% applied prostaglandins (either E1 or E2. In women with a prior cesarean, 21.4% of the hospitals performed an elective cesarean section if delivery was indicated (26.0% in 2006. In case of cervical ripening, 72.7% used mechanical methods (49.1% in 2006, 20.0% used prostaglandins (40.4% in 2006, 3.6% used a combination of prostaglandins and mechanical methods, and 3.6% used membrane-sweeping or oxytocin. Conclusions. In 2010, in The Netherlands, prostaglandins and Foley catheters were the preferred methods for cervical ripening in women without and with a prior cesarean, respectively. Use of mechanical methods in women with a prior cesarean has increased rapidly between 2006 and 2010, corresponding with decreasing use of prostaglandins and elective repeat cesarean sections.

    The objective of this prospective case-control study was to determine whether uterine corpus and cervical length measurements have a role in dysmenorrhoea aetiology in virgins. Patients with severe primary dysmenorrhoea with visual analog scale scores of ≥7 composed the dysmenorrhoea group (n = 51), while the control group (n = 51) was of women with painless menstrual cycles or with mild pain. Longitudinal and transverse axes of the uterine cervix and uterine corpus were measured. Correlation between severity of dysmenorrhoea and uterine cervix and corpus axes was calculated. Longitudinal and transverse axes of uterine cervix as well as uterine cervix volume were significantly higher in the dysmenorrhoea group compared to the controls. There was a significant positive correlation between severity of dysmenorrhoea and the length of cervical longitudinal and transverse axes and uterine cervical volume. Our findings reveal longer cervical length and greater cervical volume in young virgin patients with dysmenorrhoea and severe pain compared to those with no or less pain. PMID:27012227

    International Nuclear Information System (INIS)

    Objective: To evaluate the usefulness of magnetic resonance spectroscopic imaging in detecting local recurrence in patients with T3N0M0 prostate cancer after cryotherapy. Methods: Sixty-five patients with T3N0M0 prostate cancer underwent cryotherapy. The preoperative data of conventional MRI, MRS, transrectal ultrasound (TRUS)-guided prostate biopsy were collected. After cryotherapy, the prostate specific antigen (PSA) of all patients was detected monthly.If PSA >5 μg/L, MRI, MRS, and TRUS-guided prostate biopsy were planned within a week. If PSA was unremarkable, MRI, MRS, and TRUS-guided prostate biopsy were planned 12 months after cryotherapy. The prostate was divided 6 regions and the cancerous and noncancerous were marked. The signal-to-noise ratio (S/N) of choline (Cho), citrate (Cit) and the ratios of Cho + creatine (Cre)/Cit of each regions were measured in pre-operation and postoperation. The patients were divided into non-recurrence and recurrence group according to TRUS-guided biopsy. The S/N of Cho, Cit, and the ratio of Cho + Cre/Cit were compared between the groups before and after cryotherapy by using independent samples t-test. Results: (1) Fifteen patients were confirmed local recurrence 12 months after cryotherapy, including 11 patients with an evaluate PSA level and 4 patients with PSA unremarkable. (2) The S/N of Cho, Cit and the ratios of Cho + Cre/Cit in the cancerous and noncancerous regions before cryotherapy in the sixty-five patients were 25±9, 11±5, and 18±5, and 39 ±12, 2.33±0.60, and 0.53 ± 0.19. There had significant difference between that of two groups (t values were 11.36, 9.81, and 13.39, respectively, P=0.00). (3) In the patients with non-recurrence, The S/N of Cho, Cit in the cancerous and noncancerous regions were 4 ± 2 and 3 ± 2 (t=1.024, P=0.305), and 2±2 and 4 ±3 (t=1.147, P=0.178) and no difference was found.

  18. Exclusive brachytherapy for T1-T2 N0 cancer of the oral tongue: prognostic factors for local control

    International Nuclear Information System (INIS)

    INTRODUCTION: The files of a group of patients (pts) treated with brachytherapy alone for cancer of the oral tongue were reviewed to assess the prognostic role of T stage, volume of disease, total dose and dose-rate. PATIENTS METHODS AND RESULTS: From 1982 to 1994 46 pts (29 males, 17 females, age 38-84 years, median 63.1 years) were treated with 192 Ir brachytherapy, in 2 cases followed by prophylactic neck dissection for cancer of the oral tongue (T1N0: 19 pts; T2N0: 27 pts). Brachytherapy was performed with hairpins in the early years of the study (17 pts) and more recently with plastic tubes (29 pts), according to the Parts System. Dose ranged from 60-70 Gy with a dose-rate of 0.38-0.62 Gy/h (median 63.8 and 0.52 respectively). Volume of the disease was retrospectively assessed as the product of the three diameters of the lesion calculated for provisional dosimetry (range 0.25- 16 cc.). Median follow up is 72 mos (range: 14-153 mos). RESULTS: Overall local control was 82.6% ((38(46)) pts; T1: (18(19)), 94.7 %; T2: (22(27)), 81.5 %). Five of 8 pts who recurred were submitted to salvage surgery, and 3 of them are alive and free from disease at 34, 52 and 87 mos respectively. Recurrences appeared after 3-13 mos (median 5.5 mos) and were related to total dose ( 63 Gy (1(18)); 5.5 %) and to dose-rate ( 45 cGy/h (4(36)): 11.1 %). The volume of disease was not of prognostic significance since local control was 79.6 % ((6(28)) pts) in pts with a disease smaller than 3 cc. and 88.9 % in pts with large volume ((2(18)) pts). Seven (15.2 %) grade 3 complications (necrosis of the mandibular bone and- or of the soft tissues) were observed. Complication rate was higher in the high dose group (>63 Gy (4(18)) pts: 22.2 %) and was less affected by dose-rate (> 45 cGy/h (6(36)) pts: 16.6 %). No relationship between complications and volume was observed ( 3cc.: 16.6 %). All complications healed spontaneously. DISCUSSION AND CONCLUSION: For T1-T2 cancer of the oral tongue exclusive

    International Nuclear Information System (INIS)

    Full text: It is of interest to study the distribution of hydrogen isotopes in solid solutions of nitrogen and hydrogen in α-Ti lattice by neutron diffraction. Results of this research can give the important information about the role of hydrogen and solvent atoms as well as of strain interaction energy of interstitial atoms in the formation of structure and phase relationship in hydrogen - containing solid solutions of nitrogen in α-Ti. The aim of the present work is neutron and X-ray diffraction study of distribution of interstitial atoms in α-Ti lattice when isotopic compound of hydrogen atoms is shifted, namely in TiN0.40H0.19D0.19. Neutron diffraction patterns were obtained using the neutron diffractometer D N-500 of INP AS RUz ( λ = 1.085 A), X-ray patterns - using the X-ray diffractometer DRON-3M ( λ = 1.5418 A). The treatment of neutron diffraction patterns was carried out using the Rietveld full-profile analysis (program of DBW 3.2). The sample was prepared by Siverts method in the Institute of General and Inorganic Chemistry of RAS. According to X-ray diffraction pattern, the sample was single-phase and had hexagonal unit cell (a = 3.009; c = 4.875 A). Neutron diffraction pattern of the solid solution was indexed within the framework of space group. The neutron diffraction pattern can be accounted for only if to assume that all nitrogen atoms locate in the octahedral interstices 1(a) with coordinates 0, 0, 0; and hydrogen and deuterium isotopes locate in one type of tetrahedral interstices of two - 2 (d) - with coordinates 1/3, 2/3, z; 2/3, 1/3, z, but with different coordinate z: zH = 0.795± 0.007 and zD = 0.582± 0.004. At that, the divergence factors on Bragg maxima RBr = 5.9 %. If to assume that N and D have identical coordinate z, firstly, RBr increases up to 20 %; secondly, at that the error of determining z sharply increases, so that dz ≅ z. Therefore, the crystal structure of the sample under study is analogous with the structure which was

    Purpose: To evaluate the influence of elective inguinal node radiation therapy (INRT) on locoregional control (LRC) in patients with early-stage T2N0 anal cancer treated conservatively with primary RT. Methods and Materials: Between 1976 and 2008, 116 patients with T2 node-negative anal cancer were treated curatively with RT alone (n=48) or by combined chemoradiation therapy (CRT) (n=68) incorporating mitomycin C and 5-fluorouracil. Sixty-four percent of the patients (n=74) received elective INRT. Results: Over a median follow-up of 69 months (range, 4-243 months), 97 (84%) and 95 patients (82%) were locally and locoregionally controlled, respectively. Rates for 5-year actuarial local control, LRC, cancer-specific, and overall survival for the entire population were 81.7% ± 3.8%, 79.2% ± 4.1%, 91.1% ± 3.0%, and 72.1% ± 4.5%, respectively. The overall 5-year inguinal relapse-free survival was 92.3% ± 2.9%. Isolated inguinal recurrence occurred in 2 patients (4.7%) treated without INRT, whereas no groin relapse was observed in those treated with INRT. The 5-year LRC rates for patients treated with and without INRT and with RT alone versus combined CRT were 80.1% ± 5.0% versus 77.8% ± 7.0% (P=.967) and 71.0% ± 7.2% versus 85.4% ± 4.5% (P=.147), respectively. A trend toward a higher rate of grade ≥3 acute toxicity was observed in patients treated with INRT (53% vs 31%, P=.076). Conclusions: In cases of node-negative T2 anal cancer, the inguinal relapse rate remains relatively low with or without INRT. The role of INRT in the treatment of early-stage anal carcinoma needs to be investigated in future prospective trials.

Esse vírus de DNA infecta primariamente o epitélio e pode induzir lesões benignas ou malignas na pele e na mucosa. Alguns HPVs são considerados de alto risco, responsáveis pela progressão das lesões precursoras até câncer cervical. A infecção genital pelo HPV é comum em mulheres jovens e geralmente é transitória. Uma pequena proporção de mulheres infectadas desenvolve câncer cervical, implicando o envolvimento de fatores ambientais e fatores genéticos na carcinogênese. Essa revisão aborda a estrutura viral, classificação e patologia do HPV, história natural e fatores de risco para neoplasia cervical e perspectivas futuras com a vacina anti-HPV.Human papillomavirus (HPV has been established as an important etiological factor for the development of cervical cancer. This DNA virus primarily infects the epithelium and can induce benign and malignant lesions of the mucous membranes and skin. Some HPVs are considered high risk due to their role in malignant progression of cervical tumors. Genital HPV infections are common and usually transient among young sexually active women. Only a small fraction of infected women develop cervical cancer, implying the involvement of environmental and genetic cofactors in cervical carcinogenesis.

    Epidural steroid injections (ESI) are a common treatment for back pain management. ESI-related complications have increased with the growing number of procedures. We report a case of cervical meningomyelitis followed by multiple lumbar ESI. A 60-year-old male with diabetes mellitus presented to our hospital with severe neck pain. He had a history of multiple lumbar injections from a local pain clinic. After admission, high fever and elevated inflammatory values were detected. L-spine magnetic resonance imaging (MRI) revealed hematoma in the S1 epidural space. Antibiotic treatment began under the diagnosis of a lumbar epidural abscess. Despite the treatment, he started to complain of weakness in both lower extremities. Three days later, the weakness progressed to both upper extremities. C-spine MRI revealed cervical leptomeningeal enhancement in the medulla oblongata and cervical spinal cord. Removal of the epidural abscess was performed, but there was no neurological improvement.

    A 70-year-old Greek lady presented with fever, arthralgias of knees, cervical and lumbar pain during the last month. On clinical examination the patient was found to have tenderness of the cervical and the lumbar spine with great motion restriction. The blood tests revealed high erythrocyte sedimentation rate and C-reactive protein, abnormal liver function tests and a positive rheumatoid factor. Serological test for Brucella was positive while cervical MRI revealed epidural abscess and spondylodiscitis. Conservative treatment with streptomycin (it was substituted by rifampicin after the third week) and doxycyclin for 4 months significantly improved her symptoms. The frequency as well as the diagnosis and management of this manifestation are discussed. PMID:23188848

    Current cervical total disc replacement (TDR) designs incorporate a variety of different biomaterials including polyethylene, stainless steel, titanium (Ti), and cobalt-chrome (CoCr). These materials are most important in their utilization as bearing surfaces which allow for articular motion at the disc space. Long-term biological effects of implanted materials include wear debris, host inflammatory immune reactions, and osteolysis resulting in implant failure. We review here the most common materials used in cervical TDR prosthetic devices, examine their bearing surfaces, describe the construction of the seven current cervical TDR devices that are approved for use in the United States, and discuss known adverse biological effects associated with long-term implantation of these materials. It is important to appreciate and understand the variety of biomaterials available in the design and construction of these prosthetics and the considerations which guide their implementation.

    A 48-year-old man presented to the emergency department with complain of severe neck pain and anterior chest pain. Intermittent fever in the recent 2 days was also noted. There is a track maker over his left side of neck. The laboratory examination showed leukocytosis and high C-reactive protein level. Urine drug screen was positive for opiate. Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment. PMID:26298050

    Both tuberculosis cervical lymphadenitis (TCL) and oropharyngeal tularaemia (OT) have similar signs, symptoms and pathological findings. We aimed to investigate the frequency of tularaemia antibodies in patients diagnosed with TCL. Using data from the Tuberculosis Control Dispensaries between the years of 2008 and 2011 in Turkey, all patients diagnosed with TCL were informed about and included in the study. Control group subjects were selected from healthy blood donors who lived in the same region. After informed consent was obtained, the sera obtained from volunteer TCL patients and the control group were tested with a microagglutination technique for Francisella tularensis. Antibodies to Brucella were also investigated with a tube agglutination test for cross-reactivity in sera that were seropositive for tularaemia. Sera were obtained from a total of 1170 individuals in the TCL group and 596 in the control group from 67 of 81 provinces in Turkey. Francisella tularensis-positive antibodies were found in 79 (6.75%) cases in the TCL group and two (0.33%) cases in the control group with a titre of ≥1:80 (p < 0.01). When the presence of antibody of any titre was considered, the ratio became 8.2% (96/1170) in the TCL group and 0.67% (4/596) in the control group (p < 0.001). For the first time, with this study, tularaemia serology was found to be positive in a significant portion (6.75%) of diagnosed cases of TCL. In tularaemia endemic regions, it was concluded that tularaemia serology should be investigated in patients suspected of having TCL. PMID:23211027

    Special aspects of examination techniques and positive myelographic findings in cervical radicular avulsion are reported. In addition, the possibilities and limits of myeloscintigraphy are discussed. Some observations and experiences with neuroradiological diagnosis of cervical radicular avulsion are reported which are of importance for the prognosis in brachial plexus injuries. It is determined that no direct relationship between myelographic-findings and nerve functions damage exists. The possibility of regeneration in serious traumatic injuries with extensive dural avulsion is demonstrated in two cases. Despite neuroradiological findings suggesting severe damage and the possibility of functional restitution is emphasized. (orig.)

    Full Text Available This is a case report of a patient with history of vague chest pain and facial numbness. When the patient was subjected for evaluation he was found to have cervical Schwannoma. He was operated and was successfully treated. Schwannomas are extramedullary-intradural tumors composed of Schwann cells, which can arise from spinal nerves at any level (cervical, thoracic, lumbar, or cauda equina and most often arise from a posterior (sensory nerve root. The most common initial symptom therefore is pain in a radicular distribution. Early detection and surgery gives excellent results in such cases.

    In this study the effectiveness of computed tomographic discography (CTD) in diagnosing cervical soft disc hernia was evaluated. Twenty-five interververtebral discs of 15 cases with cervical soft disc hernia were examined with a discography and then a CT scan. Results of the CT scan were as follows: three discs were protruded, 12 discs were prolapsed, 6 discs were extruded, and 4 discs were sequestrated. The findings were helpful in determining the location of soft disc hernians between the median and posterolateral discs. They were also valuable in classifying types of hernians and surgical aproaches. (author)

  9. Nodal recurrences after exclusive brachytherapy for T1-T2 N0 cancer of the oral tongue

    International Nuclear Information System (INIS)

    INTRODUCTION: Exclusive brachytherapy represents the treatment of choice in small volume cancer of the oral tongue. In this neoplasm however the incidence of subclinical metastasis in neck nodes is not negligible, and prophylactic neck dissection is advocated by some Authors after interstitial irradiation. We have thus reviewed the incidence of nodal recurrences in a group of pts treated with brachytherapy alone for tongue cancer. PATIENTS METHODS AND RESULTS: From 1982 to 1994 44 pts (27 males, 17 females, age 35-84 years, median 63,3 years) were treated with 192 Ir interstitial irradiation alone for clinically N0 epidermoid cancer of the oral tongue (T1: 19 pts, T2: 25 pts). Brachytherapy was performed with hairpins or plastic tubes, according to the rules of the Paris system. Dose ranged from 60-70 Gy with a dose rate of 0.38-0.62 Gy/h (median: 63.8 and 0.52 respectively). Local recurrences were observed in 8 pts (18.1 %), 3 of whom are free from disease after salvage surgery. Neck nodes metastasis appeared after 3-11 months (mos) from primary treatment (median 6,3 mos) and represented the first site of failure in 16 pts (36,3 %; T1 (6(19)): 31,5 %. T2(10(25)) : 40 %; volume 3cc.: 55.5 %). After neck dissection and external radiotherapy 10 of them were rendered free from disease and are still alive at 12-123 mos. Definitive control above the clavicles was thus 75 % ((33(44)) pts). DISCUSSION AND CONCLUSION: Exclusive brachytherapy can obtain excellent local control rates in T1 T2 oral tongue cancer (81.9 % in our experience). Nodal recurrences are however frequent after interstitial irradiation in large volume cancers and salvage of pts relapsed in the neck is not easily achievable. Prophylactic neck dissection could be advisable to enhance regional control rate in these pts. The role of newer methods to evaluate neck nodes during follow up (ultrasonography and fine needle aspiration of suspicious nodes) is now being investigated in our centre

    appears that HPV DNA testing is on the way to becoming a common testing strategy in cervical cancer prevention programs. Research continues into approaches for improving the performance and cost-effectiveness of HPV detection methods. Hybrid Capture 3 will offer improved HPV typing capabilities and the Rapid Capture machine allows for robot- assisted HPV DNA testing, permitting greater test throughput. PCR test improvements are expected to contribute to the growth of flexible accurate and cost-effective HPV DNA tests. It is likely that improved diagnostic technology along with HPV genotyping and quantitation may provide more value in future. A particularly promising approach is to combine HPV DNA testing with expression levels of other markers such as proliferative or cell cycle regulatory proteins to subdivide HPV- positive women into those who are at greater risk of cancer and those who can be safely followed by screening at longer intervals.Evidencia de la utilidad clínica de la determinación de ADN del virus del papiloma humano se ha incrementado durante los últimos años, y ahora ha llegado a ser convincente.

  12. Cervical spine injury in child abuse: report of two cases

    International Nuclear Information System (INIS)

    Pediatric cervical spine injuries have rarely been reported in the setting of child abuse. We report two cases of unsuspected lower cervical spine fracture-dislocation in twin infant girls who had no physical examination findings to suggest cervical spine injury. Classic radio-graphic findings of child abuse were noted at multiple other sites in the axial and appendicular skeleton. Magnetic resonance (MR) imaging proved to be valuable in both the initial evaluation of the extent of cervical spine injury and in following postoperative changes. The unexpected yet devastating findings in these two cases further substantiate the importance of routine evaluation of the cervical spine in cases of suspected child abuse. (orig.)

    The aim of this study was to determine the frequency of abnormal cervical cytology in preoperative cervical cytology of patients diagnosed with uterine papillary serous carcinoma (UPSC) and endometrioid endometrial carcinoma (EEC). In addition, associations between abnormal cervical cytology and clinicopathologic factors were evaluated. In this multicentre study, EEC patients diagnosed at two hospitals from 1999 to 2009 and UPSC patients diagnosed at five hospitals from 1992 to 2009, were included. Revision of the histologic slides was performed systematically and independently by 3 gynecopathologists. Cervical cytology within six months before histopathologic diagnosis of endometrial carcinoma was available for 267 EEC and 80 UPSC patients. Cervical cytology with atypical, malignant, or normal endometrial cells in postmenopausal women was considered as abnormal cytology, specific for endometrial pathology. Abnormal cervical cytology was found in 87.5% of UPSC patients, compared with 37.8% in EEC patients. In UPSC, abnormal cytology was associated with extrauterine spread of disease (P=0.043). In EEC, abnormal cytology was associated with cervical involvement (P=0.034). In both EEC and UPSC patients, abnormal cervical cytology was not associated with survival. In conclusion, abnormal cervical cytology was more frequently found in UPSC patients. It was associated with extrauterine disease in UPSC patients, and with cervical involvement in EEC patients. More prospective research should be performed to assess the true clinical value of preoperative cervical cytology in endometrial cancer patients. PMID:23722512

    INTRODUCTION: A reason for not recommending subtotal hysterectomy is the risk of cervical pathology. We aimed to evaluate cervical cancer screening and to describe cervical pathology after subtotal and total hysterectomy for benign indications. METHODS: Data regarding adherence to screening.......7% were not screened. We found a minimum of one abnormal test in 28 (10.8%) after subtotal hysterectomy and one after total hysterectomy. No cervical cancers were found. CONCLUSIONS: Adherence to cervical cancer screening after subtotal hysterectomy in a Danish population is suboptimal and some patients...... have unnecessary tests performed after total hysterectomy.

    Full Text Available Abstract Background We estimated the number of women undergoing cervical cancer screening annually in Italy, the rates of cervical abnormalities detected, and the costs of screening and management of abnormalities. Methods The annual number of screened women was estimated from National Health Interview data. Data from the Italian Group for Cervical Cancer Screening were used to estimate the number of positive, negative and unsatisfactory Pap smears. The incidence of CIN (cervical intra-epithelial neoplasia was estimated from the Emilia Romagna Cancer Registry. Patterns of follow-up and treatment costs were estimated using a typical disease management approach based on national guidelines and data from the Italian Group for Cervical Cancer Screening. Treatment unit costs were obtained from Italian National Health Service and Hospital Information System of the Lazio Region. Results An estimated 6.4 million women aged 25–69 years undergo screening annually in Italy (1.2 million and 5.2 million through organized and opportunistic screening programs, respectively. Approximately 2.4% of tests have positive findings. There are approximately 21,000 cases of CIN1 and 7,000–17,000 cases of CIN2/3. Estimated costs to the healthcare service amount to €158.5 million for screening and €22.9 million for the management of cervical abnormalities. Conclusion Although some cervical abnormalities might have been underestimated, the total annual cost of cervical cancer prevention in Italy is approximately €181.5 million, of which 87% is attributable to screening.

    Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings. PMID:27115350

    A discogenic cervical headache is a subtype of cervicogenic headache (CEH) that arises from a degenerative cervical disc abnormality. The purpose of this study was to evaluate the clinical outcome of percutaneous endoscopic cervical discectomy (PECD) for patients with chronic cervical headache due to soft cervical disc herniation. Seventeen patients underwent PECD for intractable headache. The inclusion criteria were soft disc herniation without segmental instability, proven by both local anesthesia and provocative discography for headache unresponsive to conservative treatment. The mean follow-up period was 37.6 months. Fifteen of the 17 patients (88.2%) showed successful outcomes based on the Macnab criteria. Pain scores on a visual analog scale (VAS) improved from a preoperative mean of 8.35{+-}0.79 to 2.12{+-}1.17, postoperatively (P<0.01). The mean disc height decreased from 6.81{+-}1.08 to 5.98{+-}1.07 mm (P<0.01). There was no newly developed segmental instability or spontaneous fusion on follow-up radiography. In conclusion, PECD appears to be effective for chronic severe discogenic cervical headache under strict inclusion criteria. (orig.)

    Full Text Available Background: Although preventable, cervical cancer, an AIDS-related disease, is the second most common cancer amongst South African women and the most common cancer amongst black women. Objective: The objective of the study was to determine what women being treated for HIV and AIDS at a specific healthcare centre in Johannesburg knew about cervical cancer and cervical screening. Method: A survey design was used, with data gathered by means of a self-administered questionnaire. Convenience sampling selected 315 women to participate (n = 315. Descriptive statistics were used to analyse the data and chi-square testing found associations between categorical variables. Results: The majority of respondents (78.7%; n = 248 indicated that they had heard of cervical cancer and 62.9% (n = 198 knew about the Pap smear, with nurses and doctors being the primary source of information. Of the women who knew about the Pap smear, less than one-third had had a smear done, the main reason being fear of the procedure. Conclusion: The study provided evidence that women attending the specific HIV clinic were more knowledgeable about cervical cancer and screening than those of unknown HIV status involved in previous studies. Knowledge was still at a low level, especially when their exceptionally high risk was taken into account. Once again it was found that having knowledge did not necessarily mean having had a Pap smear, which remains a huge challenge in the prevention of cervical cancer.

  5. Two cases of high cervical cord tumor

    International Nuclear Information System (INIS)

    Two cases of high cervical cord tumor are presented. Case 1 is an intradural extramedullary meningioma located at the foramen magnum. Case 2 is an extradural neurinoma originated from left C2 spinal nerve root. In each case high resolution computed tomography and myelography, especially that of axial view, visualized extramedullary mass lesion.FIn recent years it has been stressed that high resolution computed tomography is useful in the diagnosis of high cervical cord lesion, and this idea is quite reasonable from our experiences. On the other hand, it has been mentioned that myelography often gives false negative results as far as high cervical cord lesion is concerned, which is mainly because relative width of the subarachnoid space in the region of the foramen magnum.FOur experience indicated that in myelographic examination of foramen magnum tumor it is advisable to add axial view to ordinary P-A and lateral views. Bacause axial high cervical myelography gives an image similar to computed tomogram of this region, this technique not only increases the diagnostic value of myelography but also, in some cases, substitutes for computed tomography which costs very much.

  6. Therapeutic Vaccination for HPV Induced Cervical Cancers

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    Worldwide, cancer of the cervix is the second leading cause of cancer death in women: each year, an estimated 500,000 cases are newly diagnosed. Among populations, there are large differences in incidence rates of invasive cervical cancer: these reflect the influence of environmental factors, screening Papanicolaou (Pap) tests, and treatment of pre-invasive lesions. The high-risk human papillomavirus (HPV) subtypes 16, 18, 31, 33, and 51 have been recovered from more than 95% of cervical cancers. We have made great strides in understanding the molecular mechanism of oncogenesis of this virus, focusing on the action of the E6 and E7 viral oncoproteins. These oncoproteins function by inactivating cell cycle regulators p53 and retinoblastoma (Rb), thus providing the initial event in progression to malignancy. Cervical cancers develop from precursor lesions, which are termed squamous intraepithelial lesions (SIL) and are graded as high or low, depending on the degree of disruption of epithelial differentiation. Viral production occurs in low-grade lesions and is restricted to basal cells. In carcinomas, viral DNA is found integrated into the host genome, but no viral production is seen. The well-defined pre-invasive stages, as well as the viral factors involved at the molecular level, make cervical carcinoma a good model for investigating immune therapeutic alternatives or adjuvants to standard treatments.

    Introduction Cervical intraepithelial neoplasias (CIN) represent precursor lesions of cervical cancer. These neoplastic lesions are traditionally subdivided into three categories CIN 1, CIN 2, and CIN 3, using microscopical criteria. The relation between grades of cervical intraepithelial neoplasia (CIN) and its fractal dimension was investigated to establish a basis for an objective diagnosis using the method proposed. Methods Classical evaluation of the tissue samples was performed by an experienced gynecologic pathologist. Tissue samples were scanned and saved as digital images using Aperio scanner and software. After image segmentation the box counting method as well as multifractal methods were applied to determine the relation between fractal dimension and grades of CIN. A total of 46 images were used to compare the pathologist's neoplasia grades with the predicted groups obtained by fractal methods. Results Significant or highly significant differences between all grades of CIN could be found. The confusion matrix, comparing between pathologist's grading and predicted group by fractal methods showed a match of 87.1%. Multifractal spectra were able to differentiate between normal epithelium and low grade as well as high grade neoplasia. Conclusion Fractal dimension can be considered to be an objective parameter to grade cervical intraepithelial neoplasia. PMID:25302712

    Predicting neck response and injury resulting from motor vehicle accidents is essential to improving occupant protection. A detailed human cervical spine finite element model has been developed, with material properties and geometry determined a priori of any validation, for the evaluation of global kinematics and tissue-level response. Model validation was based on flexion/extension response at the segment level, tension response of the whole ligamentous cervical spine, head kinematic response from volunteer frontal impacts, and soft tissue response from cadaveric whole cervical spine frontal impacts. The validation responses were rated as 0.79, assessed using advanced cross-correlation analysis, indicating the model exhibits good biofidelity. The model was then used to evaluate soft tissue response in frontal impact scenarios ranging from 8G to 22G in severity. Disc strains were highest in the C4-C5-C6 segments, and ligament strains were greatest in the ISL and LF ligaments. Both ligament and disc fiber strain levels exceeded the failure tolerances in the 22G case, in agreement with existing data. This study demonstrated that a cervical spine model can be developed at the tissue level and provide accurate biofidelic kinematic and local tissue response, leading to injury prediction in automotive crash scenarios.

    First-principles calculations are performed to study Ag and Ag-alloy adsorption stability on GaN(0 0 0 1) surface. We find Ag only contact to GaN surface is unstable under high temperature. While Ag-alloy adsorption exhibits better adsorption stability and electronic properties than that of the Ag only contact,due to the enhanced interaction between Ag-alloy and GaN(0 0 0 1) surface. The Ag-alloy, particularly AgNi, is proposed to be used as very promising ohmic contact to GaN for practical applications

    Thermal-energy reaction rate coefficients and product ion distributions have been measured for reactions of both the ground state and metastable electronic states of 02+, N0+ and 0+ with several neutral species, using a selected-ion flow tube. In general the excited-ion reaction rates are fast, frequently approaching the Langevin limit. Collisional quenching occurs for the reactions of N0+sup(star) with N2,02 and H2 and the quenching rates have been determined. The ion source also provided a substantial yield of doubly charged 02 permitting some measurements of reaction rates of 022+. (author)

  5. Improved hydrogen release from LiB0.33N0.67H2.67 with metal additives: Ni, Fe, and Zn

    International Nuclear Information System (INIS)

    We have examined the effect of adding small quantities of Fe, Ni, and Zn, or their dichlorides, on the dehydrogenation temperature of the new quaternary hydride material LiB0.33N0.67H2.67. NiCl2 proved to be an especially effective dehydrogenation promoter. The hydrogen release temperature, represented by the temperature T 1/2 at which the hydrogen release reaction is half completed, decreased by ΔT 1/2 = -104 oC for 5 wt% NiCl2 addition and by ΔT 1/2 = -112 oC for 11 wt% NiCl2 addition compared to that of additive-free LiB0.33N0.67H2.67. This represents a significant improvement over the maximum temperature reduction of ΔT 1/2 = -90 oC achieved previously with Pt/Vulcan carbon additive (Pt nanoparticles supported on a Vulcan carbon substrate). Transmission electron microscopy on LiB0.33N0.67H2.67 + 11 wt% NiCl2 revealed uniformly dispersed nanoparticles with diameters less than 8 nm within the LiB0.33N0.67H2.67 matrix, consistent with reduction of the NiCl2 to metallic Ni during synthesis by ball milling. Mass spectrometry of the evolved gas showed that the total amount of NH3 released concurrently during dehydrogenation of LiB0.33N0.67H2.67 + 5 wt% NiCl2 was reduced by an order of magnitude compared to the additive-free material, and by a factor of four compared to LiB0.33N0.67H2.67 + 5 wt% Pt/Vulcan carbon. In contrast to additive-free LiB0.33N0.67H2.67, which melts completely above 190 oC and releases hydrogen from the liquid state only above about 250 oC, hydrogen release from LiB0.33N0.67H2.67 + 5 wt% NiCl2 is accompanied by partial melting above 190 oC plus transformation to a new, hydrogen-poor solid intermediate phase. Addition of 5 wt% FeCl2 gave ΔT 1/2 = -36 oC, but Fe, Zn, and ZnCl2 additives did not produce significant improvement

  6. Cervical cancer: Can it be prevented?

    Science.gov (United States)

    Aggarwal, Pakhee

    2014-10-10

    Cervical cancer prevention requires a multipronged approach involving primary, secondary and tertiary prevention. The key element under primary prevention is human papilloma virus (HPV) vaccination. So far, only prophylactic HPV vaccines which prevent HPV infection by one or more subtypes are commercially available. Therapeutic HPV vaccines which aid in clearing established infection are still under trial. Secondary prevention entails early detection of precancerous lesions and its success is determined by the population coverage and the efficacy of the screening technique. A number of techniques are in use, including cytology, visual inspection (using the naked eye, magnivisualizer, acetic acid and Lugol's iodine), HPV testing and a combination of these methods. Updated screening guidelines have been advocated by the American Cancer Society in light of the role of HPV on cervical carcinogenesis. Recent research has also focussed on novel biomarkers that can predict progression to cancer in screen positive women and help to differentiate those who need treatment from those who can be left for follow-up. Last but not the least, effective treatment of precancerous lesions can help to reduce the incidence of invasive cervical cancer and this constitutes tertiary prevention. A combination of these approaches can help to prevent the burden of cervical cancer and its antecedent morbidity and mortality, but all of these are not feasible in all settings due to resource and allocation constraints. Thus, all countries, especially low and middle income ones, have to determine their own cocktail of approaches that work before we can say with certainty that yes, cervical cancer can be prevented.

Major advances but still insufficient achievements in the treatment of locally advanced and high-risk early stage patients have occurred in the last decade with the incorporation of concurrent cisplatin with radiation and, lately, gemcitabine added to cisplatin chemoradiation. Despite a number of clinical studies incorporating molecular-targeted therapy as radiosensitizers being in progress, so far, only antiangiogenic therapy with bevacizumab added to cisplatin chemoradiation has demonstrated safety and shown encouraging results in a Phase II study. In advanced disease, cisplatin doublets do not have a great impact on the natural history of the disease with median survival rates not exceeding 13 months. The first Phase III study of bevacizumab, added to cisplatin or a non-cisplatin-containing doublet, showed significant increase in both overall survival and progression-free survival. Further studies are needed before bevacizumab plus chemotherapy can be considered the standard of care for advanced disease. Characterization of the mutational landscape of cervical cancer has already been initiated, indicating that, for now, few of these targetable alterations match with available agents. Progress in both the mutational landscape knowledge and developments of novel targeted therapies may result in more effective and individualized treatments for cervical cancer.

The objective of this study was to investigate the functional and failure biomechanics of the cervical spine across multiple axes of loading throughout maturation. A correlational study design was used to examine the relationships governing spinal maturation and biomechanical flexibility curves and tolerance data using a cadaver human in vitro model. Eleven human cadaver cervical spines from across the developmental spectrum (2-28 years) were dissected into segments (C1-C2, C3-C5, and C6-C7) for biomechanical testing. Non-destructive flexibility tests were performed in tension, compression, flexion, extension, lateral bending, and axial rotation. After measuring their intact biomechanical responses, each segment group was failed in different modes to measure the tissue tolerance in tension (C1-C2), compression (C3-C5), and extension (C5-C6). Classical injury patterns were observed in all of the specimens tested. Both the functional (pmechanics exhibited significant relationships with age. Nonlinear flexibility curves described the functional response of the cervical spine throughout maturation and elucidated age, spinal level, and mode of loading specificity. These data support our understanding of the child cervical spine from a developmental perspective and facilitate the generation of injury prevention or management schema for the mitigation of child spine injuries and their deleterious effects.

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    Population cervical screening programmes are necessary for meaningfully reducing cervical cancer morbidity and mortality. Because of the high incidence of cervical cancer in South Africa, the need for a national screening programme has become evident. The success of such a programme will depend on, among others, the level of cervical cancer awareness among the target population, and their willingness to utilise cytological services and to comply with treatment and follow up protocols. We conducted a survey among female university students, as an elite group of women, to determine their level of cervical cancer awareness and the prevalence of the major risk factors for cervical cancer among them, their rate of utilisation of existing Pap smear services, and their attitudes to Pap smears in general. The majority of respondents were young, single (93.0%) and sexually active (86.9%,) having initiated sexual activity at a mean age of 17.27 +/- 2.18 years. There was a high prevalence of the major risk factors for cervical cancer among the respondents, and these included initiation of coitus before 18 years (53.3%), multiple sexual partners (73.6%), male partner with other partners (37.7%), and previous history of sexually transmitted diseases (42.2%) and vulval warts (4.7%). Their overall knowledge of cervical cancer was poor, although the majority of respondents were able to identify the major risk factors from a given list. This level of awareness of cervical cancer risk factors, however, did not translate into appreciation of personal risk of cervical cancer, safer sex practices or utilisation of Pap smear services. In conclusion, this elite group of women is at a high risk of cervical cancer and would benefit from cervical screening programmes. This would have to be coupled with measures to increase the level of awareness and knowledge of cervical cancer and its prevention. PMID:9803633

  12. Nuclear expression of Rac1 in cervical premalignant lesions and cervical cancer cells

    International Nuclear Information System (INIS)

    Abnormal expression of Rho-GTPases has been reported in several human cancers. However, the expression of these proteins in cervical cancer has been poorly investigated. In this study we analyzed the expression of the GTPases Rac1, RhoA, Cdc42, and the Rho-GEFs, Tiam1 and beta-Pix, in cervical pre-malignant lesions and cervical cancer cell lines. Protein expression was analyzed by immunochemistry on 102 cervical paraffin-embedded biopsies: 20 without Squamous Intraepithelial Lesions (SIL), 51 Low- grade SIL, and 31 High-grade SIL; and in cervical cancer cell lines C33A and SiHa, and non-tumorigenic HaCat cells. Nuclear localization of Rac1 in HaCat, C33A and SiHa cells was assessed by cellular fractionation and Western blotting, in the presence or not of a chemical Rac1 inhibitor (NSC23766). Immunoreacivity for Rac1, RhoA, Tiam1 and beta-Pix was stronger in L-SIL and H-SIL, compared to samples without SIL, and it was significantly associated with the histological diagnosis. Nuclear expression of Rac1 was observed in 52.9% L-SIL and 48.4% H-SIL, but not in samples without SIL. Rac1 was found in the nucleus of C33A and SiHa cells but not in HaCat cells. Chemical inhibition of Rac1 resulted in reduced cell proliferation in HaCat, C33A and SiHa cells. Rac1 is expressed in the nucleus of epithelial cells in SILs and cervical cancer cell lines, and chemical inhibition of Rac1 reduces cellular proliferation. Further studies are needed to better understand the role of Rho-GTPases in cervical cancer progression

  14. Periodicity of about 27 days in the cosmic-ray intensity and Kp data during the solar cycle n0 18

    International Nuclear Information System (INIS)

    The quasi-periodical variations of the cosmic-ray intensity, with a period of about 27 days, have been studied in the data recorded through shielded ionization chambers at Huancayo and at Cheltenham during the solar cycle N0 18 (1944-53). The same investigation has been extended to the contemporary variations of the geomagnetic index Kp. The results obtained by the periodical analysis through the Vercelli's method (amplitudes and periods) and by the calculation of the correlation coefficients among the data of different variables are reported and discussed. Particularly, a detailed diagram is reported on the behaviour of the single oscillation amplitudes, extended also to the following solar cycles N0 19 (1954-64) and N0 20 (1965-74), which have previously been analysed; this diagram has been compared with a similar one obtained by Bazilevskaya et al. in other place, in the interval 1957-73. The amplitude behaviour of the solar cycle N0 18 validates a discrepancy versus the sunspot Wolf number, already realized through another statistical procedure by Venkatesan. (Author)

    We consider two-dimensional $\\mathcal{N}=(0,2)$ sigma models with the CP(1) target space. A minimal model of this type has one left-handed fermion. Nonminimal extensions contain, in addition, $N_f$ right-handed fermions. Our task is to derive expressions for the $\\beta$ functions valid to all orders. To this end we use a variety of methods: (i) perturbative analysis; (ii) instanton calculus; (iii) analysis of the supercurrent supermultiplet (the so-called hypercurrent) and its anomalies, and some other arguments. All these arguments, combined, indicate a direct parallel between the heterotic $\\mathcal{N}=(0,2)$ CP(1) models and four-dimensional super-Yang-Mills theories. In particular, the minimal $\\mathcal{N}=(0,2)$ CP(1) model is similar to ${\\mathcal N}=1$ supersymmetric gluodynamics. Its exact $\\beta$ function can be found; it has the structure of the Novikov-Shifman-Vainshtein-Zakharov (NSVZ) $\\beta$ function of supersymmetric gluodynamics. The passage to nonminimal $\\mathcal{N}=(0,2)$ sigma models is eq...

  17. Evaluation of critical thickness of GaP0.98N0.02 layer on GaP substrate by synchrotron X-ray diffraction topography

    International Nuclear Information System (INIS)

    GaP0.98N0.02 layers having a thickness from 75 nm to 600 nm are grown on GaP substrates by metalorganic vapor phase epitaxy. Back-reflection X-ray topographs made with a synchrotron radiation of the thick GaP0.98N0.02 layers reveal images of misfit dislocations. The critical thickness of the grown GaP0.98N0.02 layer on GaP substrate is evaluated from the topographs to be about 200 nm. The strain relaxation is also observed from high resolution X-ray diffraction curves. X-ray diffraction curves and atomic force microscopy studies indicate that the GaP0.98N0.02 layers with thickness smaller than 200 nm possess a very good crystal quality, an atomically smooth surface with a roughness less than 0.3 nm and a well-defined interface without misfit dislocations between the layer and the substrate. - Highlights: • GaPN layers fabricated by metalorganic vapor phase epitaxy • High-resolution XRD, XRD topography, and AFM used • XRD topographs of misfit dislocations in GaPN layers on GaP substrates • Evaluated the critical thickness for formation of misfit dislocations at interface • Comparison between experimental and theoretical critical thickness

    Full Text Available In a national program to combat cervical uterine cancer (CUC four basic elements should exist: primary prevention, early detection, diagnosis/treatment and palliative care. Of these, early detection is the most effective modality. One of the purposes of Evidence-Based Practice (EBP is to encourage the use of research results with the assistance provided, reinforcing the importance of research for clinical practice. This study aimed to evaluate the evidence available in the literature regarding effective nursing interventions for the early detection of CUC. The selection of articles was performed in the databases: Scopus, PubMed, CINAHL, Lilacs and Cochrane. The sample of this review consisted of seven articles, with evidence levels 1, 2 or 3. The behavioral, cognitive and social interventions, showed positive effects in the early detection of CUC, especially the interactive cognitive interventions. It is suggested, when appropriate, to use a combination of interventions in order to obtain a more effective result.En un programa nacional de combate al cáncer cervicouterino (CCU deben existir cuatro elementos básicos: prevención primaria, detección precoz, diagnóstico/tratamiento y cuidados paliativos.

    Full Text Available Cervical cancer incidence and mortality estimates for 2000 are presented for the 21 Latin American countries, using estimates from the statistical package GLOBOCAN 2000. Additional data on time-trends are also presented, using the WHO mortality database. By the year 2000, some 76 000 cervical cancer and almost 30 000 deaths were estimated for the whole region, which represent 16% and 13% of the world burden, respectively. Thus, Latin American countries are among those with highest incidence rates in the world, together with countries from Sub-Saharan Africa, South and South East Asia. Variation in incidence among countries is large. Very high rates are found in Haiti (ASR 93.9 per 100 000, Nicaragua (ASR 61.1 per 100 000 and Bolivia (ASR 58.1 per 100 000. It seems unlikely that differences in risks in the region can be explained as the result of screening activities. Several descriptive studies carried out to evaluate the screening programmes in Latin America have pointed out problems related to insufficient coverage and frequency of screening. Other related problems include inadequate collection and reading of cytological samplings as well as incomplete follow-up of women after the test. The main challenge for Latin America countries remains on how to organize effective screening programmes, and for this, a real and urgent commitment from public health services and decision-makers in the region is needed.Se presentan estimaciones de la incidencia y de la mortalidad por cáncer cervical para los 21 países latinoamericanos en el año 2000.

    We evaluated the prognostic significance of T3 subtypes and the role of adjuvant radiotherapy in patients with resected the American Joint Committee on Cancer stage IIB T3N0M0 non-small cell lung cancer (NSCLC). T3N0 NSCLC patients who underwent resection from January 1990 to October 2009 (n = 102) were enrolled and categorized into 6 subgroups according to the extent of invasion: parietal pleura chest wall invasion, mediastinal pleural invasion, diaphragm invasion, separated tumor nodules in the same lobe, endobronchial tumor <2 cm distal to the carina, and tumor-associated collapse. The median overall survival (OS) and disease-free survival (DFS) were 55.3 months and 51.2 months, respectively. In postoperative T3N0M0 patients, the tumor size was a significant prognostic factor for survival (OS, p = 0.035 and DFS, p = 0.035, respectively). Patients with endobronchial tumors within 2 cm of the carina also showed better OS and DFS than those in the other T3 subtypes (p = 0.018 and p = 0.016, respectively). However, adjuvant radiotherapy did not cause any improvement in survival (OS, p = 0.518 and DFS, p = 0.463, respectively). Only patients with mediastinal pleural invasion (n = 25) demonstrated improved OS and DFS after adjuvant radiotherapy (n = 18) (p = 0.012 and p = 0.040, respectively). The T3N0 NSCLC subtype that showed the most favorable prognosis is the one with endobronchial tumors within 2 cm of the carina. Adjuvant radiotherapy is not effective in improving survival outcome in resected T3N0 NSCLC.

    International Nuclear Information System (INIS)

    The first-principles calculations are performed to investigate the mechanical properties and electronic structure of TiC, Ti0.75W0.25C, Ti0.75W0.25C0.75N0.25, TiC0.75N0.25 and TiN. Density functional theory and ultrasoft pseudopotentials are used in this study. From the formation energy, it is found that nitrogen can increase the stability of TiC. The calculated elastic constants and elastic moduli of TiC compare favorably with other theoretical and experimental values. Tungsten and nitrogen are observed to significantly increase the bulk, shear and Young's modulus of TiC. Through the analysis of B/G and Cauchy pressure, tungsten can significantly improve the ductility of TiC. The electronic structure of TiC, TiN, Ti0.75W0.25C, Ti0.75W0.25C0.75N0.25, and TiC0.75N0.25 are used to describe nonmetal-metal and metal-metal bonds. Based on the Mulliken overlap population analysis, the hardness values of TiC, Ti0.75W0.25C, Ti0.75W0.25C0.75N0.25, TiC0.75N0.25 and TiN are estimated.

  5. Cervical invasion of endometrial carcinoma - evaluation by parasagittal MR imaging

    International Nuclear Information System (INIS)

    Twenty-seven consecutive patients were examined by T2-(1800/70 ms) and postcontrast T1-weighted (600/15) spin echo (SE) or dynamic (200/15) SE MR imaging to determine the usefulness of parasagittal MR imaging in assessing cervical invasion of endometrial carcinoma. The images were obtained in a direction parallel to the longitudinal axis of the uterus (parasagittal). The cervical epithelium, being hyperintense on the late phase dynamic and postcontrast T1-weighted SE images, had disappeared partially or totally in all 4 patients with cervical invasion. The enhanced cervical epithelium was completely seen in one patient with the tumor protruding into the cervical canal in a polyp-like form without cervical epithelial invasion. The same was also seen in the 22 patients with the tumor remaining in the corpus cavity. The enhanced parasagittal MR images facilitated the evaluation of the extent of the endometrial carcinoma.

    Full Text Available Objective. Vietnamese American women are at the greatest risk for cervical cancer but have the lowest cervical cancer screening rates. This study was to determine whether demographic and acculturation, healthcare access, and knowledge and beliefs are associated with a prior history of cervical cancer screening among Vietnamese women. Methods. Vietnamese women (n=1450 from 30 Vietnamese community-based organizations located in Pennsylvania and New Jersey participated in the study and completed baseline assessments. Logistic regression analyses were performed. Results. Overall levels of knowledge about cervical cancer screening and human papillomavirus (HPV are low. Factors in knowledge, attitude, and beliefs domains were significantly associated with Pap test behavior. In multivariate analyses, physician recommendation for screening and having health insurance were positively associated with prior screening. Conclusion. Understanding the factors that are associated with cervical cancer screening will inform the development of culturally appropriate intervention strategies that would potentially lead to increasing cervical cancer screening rates among Vietnamese women.

  7. Evaluation of the cervical neural foramina with MR imaging

    International Nuclear Information System (INIS)

    Accurately diagnosing the causes of cervical radiculopathy with MR imaging requires better understanding of the anatomic relationships in the cervical neural foramina. The cervical foramina were studied in three ways: (1) In cadavers, the paravertebral veins were injected with paramagnetic contrast material. Cryomicrotome sections were then correlated with MR images. (2) In patients, the cervical foramina were studied with MR imaging with intravenous Gd-DTPA. (3) Normal volunteers were scanned using spin-echo and gradient-echo techniques. The nerve root sheaths, ganglia, vessels, and bone margins of the cervical foramina can be well demonstrated by MR imaging. Intravenous Gd-DTPA enhances some normal structures in the foramen. The authors report on optimal pulse sequences for evaluating the cervical neural foramina

    @@ The common symptoms of cervical spondylopathy include dizziness and vertigo, headache, neck rigidity and numbness, or pain in the shoulders, arms, and fingers. Modem medicine has divided cervical spondylopathy into 6 types, namely, the cervical,radicular, spinal, vertebroarterial, sympathetic, and the mixed types. In TCM, according to the main symptoms of dizziness and vertigo, cervical spondylopathy is traditionally called ‘cervical vertigo'. Having been engaged in TCM for more than 40 years, Prof. Luo Zhiqiang (罗致强) has acquired a profound and unique knowledge about this disorder and obtained quite good therapeutic results. The following is a brief introduction of his experience in the TCM treatment of cervical vertigo.

  9. Relationships between radiography of cervical vertebrae and histopathology of the cervical cord in wobbling 19 foals

    International Nuclear Information System (INIS)

    Nineteen wobbling foals (17 males and 2 females) showing lameness of hindlimbs at 6 to 21 months of age were investigated radiographically and histopathologically. Minimum sagittal diameter (MSD), minimum flexion diameter (MFD) and minimum dural sagittal diameter (MDD) were measured on plain radiograms or myelograms taken at neutral and flexed positions as indicators of narrowed vertebral canal. After necropsy, the cervical spines and the spinal cord were examined macroscopically and respectively the relationships between radiographic findings and the corresponding morphological lesions were evaluated. Radiographically, lower values than each minimum reference limits were recorded in 14 foals in MSD, 5 foals in MFD and 6 foals in MDD, respectively. According to the histopathologic examination, the disappearance of axons and myelin sheaths, vacuolated spongy degeneration and appearance of macrophages were recognized symmetrically in the white matter of the cervical cord. These lesions were centrally located at the spinal cord radiographically demonstrated as compressed sites in 12 out of 17 foals examined. Macroscopically, asymmetrical overgrowth of one side of the process, encroachment of articular processes into the intervertebral foramina and proliferation of bone around articular facets were observed in the articular processes of bone specimens in the caudal neck of 6 foals. In conclusion, the equine incoordination might mainly be caused by the cervical stenotic myelopathy resulting from cervical vertebral malformation, and therefore the cervical vertebral radiography, especiallymyelography, is quite very important and effective for the diagnosis of wobbling foals

    2007-01-01

    Objective:To investigate a novel surgical method for multilevel cervical spondylotic myelopathy (CSM). Methods: Totally 21 patients with multilevel CSM undergoing a novel surgical procedure from April 2001 to January 2004 were analyzed retrospectively. All patients experienced anterior cervical decompression surgery in subsection, autograft fusion and internal fixation. Preoperative, immediate postoperative and follow-up image data, X-rays and semi-quantitative Japanese orthopaedics association (JOA) scores were used to evaluate the restoration of lordosis (Cobb's angle), intervertebral heights, the stability of the cervical spine and the improvement of neurological impairment. Results: Preoperative symptoms were markedly alleviated or disappeared in most of the patients. According to the JOA scores, the ratio of improvement in neurological function was 72.2%, including excellent in 9 cases (42.9%), good in 7 cases (33.3%), fair in 3 cases (14.3%) and poor in 2 cases (9.5%). Immediate postoperative X-rays showed obvious improvements in lordosis and in the intervertebral height of the cervical spine (P<0.01). There is no evidence of instrument failure during the mean follow-up period of 14.2 months (9-24 months, P>0.01). Conclusion:Anterior cervical decompression in subsection, autograft fusion and internal fixation is a rational effective method for the surgical treatment of multilevel CSM.

    International Nuclear Information System (INIS)

    Objective: To evaluate the safety and effectiveness of CT-guided cervical interlaminar epidural steroid injection for the treatment of cervical radiculopathy. Methods: CT-guided cervical interlaminar epidural steroid injection was performed in 32 patients with cervical radioculopathy, encountered during the period of Dec. 2006 to June 2008, as the patients failed to respond to the conservative treatment in 2 weeks. The clinical data and the imaging findings were retrospectively analyzed. Before and after the procedure, visual analogue scale (VAS) and Odom criteria were used to evaluate the pain of the patient. Results: Three months after the injection, improvement judged by Odom criteria was seen in 28 patients (87.5%), and the mean pain relief value of VAS was 5.88 ± 1.10. No significant difference in effective rate and in VAS score (P>0.05) was found between protrusion group and degenerative group, between the group with the course over 6 months and the group with the course below 6 months, also between the group receiving one injection and the group receiving the second injection. Conclusion: CT-guided fine needle (23 gauge) puncture epidural steroid (Decadron) 'target spot' injection is an ideal alternative for the treatment of cervical radiculopathy, especially for the patients who fails to respond to the conservative treatment.

    Although cervical cancer is preventable with early detection, it remains the second most common malignancy among women. An understanding of how proteins change in their expression during a particular diseased state such as cervical cancer will contribute to an understanding of how the disease develops and progresses. Potentially, it may also lead to the ability to predict the occurrence of the disease. With this in mind, we aimed to identify differentially expressed proteins in the plasma of cervical cancer patients. Plasma from control, cervical intraepithelial neoplasia (CIN) grade 3 and squamous cell carcinoma (SCC) stage IV subjects was resolved by two-dimensional gel electrophoresis and the resulting proteome profiles compared. Differentially expressed protein spots were then identified by mass spectrometry. Eighteen proteins were found to be differentially expressed in the plasma of CIN 3 and SCC stage IV samples when compared with that of controls. Competitive ELISA further validated the expression of cytokeratin 19 and tetranectin. Functional analyses of these differentially expressed proteins will provide further insight into their potential role(s) in cervical cancer-specific monitoring and therapeutics.

    Full Text Available Aims and Objectives: The alignment of upper and lower cervical spine is presumed to be closely interrelated and the knowledge of this is mandatory when performing occipito-cervical and upper cervical fusions. The aim of this study was to establish standard values for upper and lower cervical spine alignment in the Indian population. Materials and Methods: Five hundred eighteen asymptomatic volunteers (261 males and 257 females between 12 and 80 years of age underwent lateral radiography with their neck in the neutral position. Angles for occipital to 2nd cervical (Oc-C2, 1st to 2nd cervical (C1-C2 and sagittal alignment of 2nd to 7th cervical vertebrae (C2-C7 were measured. Statistical analyses were performed using a statistical package SPSS 10 for windows and the students ′t′ test. Results: The mean Oc-C2, C1-C2 and C2--C7 angles were 14.66 + 9.5°, 25.6 + 7.9° and 16.8 + 12.7° in male, while same angles in female were 15.59 + 8.26°, 26.9 + 6.8° and 9.11 + 10.4° respectively. Weak statistically significant negative correlation was observed between the measured angles of the upper (Oc-C2 and C1-C2 and lower (C2-C7 cervical spines, which means if the lordosis of the occiput and upper cervical spine increases (if the Oc-C2 angle increases, the alignment of lower cervical spine becomes kyphotic and vice versa. This negative correlation was stronger between the Oc-C2 and C2-C7 angles than between the C1-C2 and C2-C7 angles. Conclusions: Relationship between alignment of the upper and the lower cervical spine should be taken into consideration when performing cervical fusion.

    Criteria for return to sports and athletic activities after cervical spine surgery are unclear. There is limited literature regarding the outcomes and optimal criteria. Determining return to play criteria remains a challenge and continues to depend on the experience and good judgment of the treating surgeon. There is strong consensus in the literature, despite lack of evidence-based data, that athletes after single-level anterior cervical discectomy and fusion (ACDF) may safely return to collision and high-velocity sports. The athlete should be counseled and managed on a case-by-case basis, taking into consideration the type of sport, player-specific variables, and type of surgery performed. PMID:27543397

    Langerhans cell histiocytosis (LCH), a disorder of the phagocytic system, is a rare condition. Moreover, spinal involvement causing myelopathy is even rare and unusual. Here, we report a case of atypical LCH causing myelopathy, which was subsequently treated by corporectomy and fusion. An 8-year-old boy presented with 3 weeks of severe neck pain and limited neck movement accompanying upper and lower limbs motor weakness. CT scans revealed destruction of C5 body and magnetic resonance imaging showed a tumoral process at C5 with cord compression. Interbody fusion using anterior cervical plate packed by autologus iliac bone was performed. Pathological examination confirmed the diagnosis of LCH. After the surgery, the boy recovered from radiating pain and motor weakness of limbs. Despite the rarity of the LCH in the cervical spine, it is necessary to maintain our awareness of this condition. When neurologic deficits are present, operative treatment should be considered. PMID:22552159
