Avaliação da coluna vertebral: relação entre gibosidade e curvas sagitais por método não-invasivo

Os objetivos do estudo foram avaliar o alinhamento, no plano sagital, da coluna de indivíduos com alterações na medida da gibosidade, comparando com um grupo sem alterações; testar a confiabilidade do instrumento utilizado e verificar se existem correlações entre as medidas da gibosidade e os valores das curvaturas vertebrais. Foram avaliados 40 jovens, divididos em grupo controle - ausência ou presença de gibosidades inferiores a 0,5 cm na curvatura torácica e 0,7 cm na lombar (n=20) e, grupo experimental - gibosidades superiores às descritas (n=20). A gibosidade e as curvaturas no plano sagital foram mensuradas com um instrumento adaptado a um nível d'água e o teste de Adams. As coletas foram realizadas em duas datas distintas, nos dois grupos. Após aplicação do teste Mann-Whitney não foi encontrada diferença entre as ocasiões de coletas e, emparelhando-se os grupos, foi encontrada diferença apenas na medida cervical. Na verificação de existência de relação entre as medidas coletadas, foi encontrada correlação linear (Spearmann) no grupo controle - curvatura torácica e gibosidade torácica; em ambos os grupos - curvaturas torácica e lombar; e no grupo experimental - gibosidade torácica e as curvaturas lombar e sacral e, curvatura sacral e curvaturas torácica e lombar. Pôde-se concluir que a medida da gibosidade tem relações com as curvaturas no plano sagital. Por ser um método confiável, simples e acessível, pode ser reproduzido sem altos custos financeiros e sem causar prejuízo à saúde do paciente.

Avaliação do uso de imobili zação externa após descompressão e fusão cervical por via anterior. Revisão Sistemática

This study aims to evaluate safety and effectiveness of the use of orthesis in postoperative degenerative disorders of the cervical spine. Although widely used, there are not defined criteria for the use of cervical collars, and their importance on cervical arthrodesis. A systematic literature review was undertaken and a multicentre controlled clinical trial comprising 32 specialized services, with a total of 257 patients who met the inclusion criteria of the review. Clinical and radiographic outcomes were compared in post surgical patients that used or not rigid cervical collar during 6 to 12 weeks after surgery. The evidence available on literature, although weak, suggests that cervical collar decreases the clinical scores in first weeks after surgery. Furthermore, it does not alter the rate of fusion when used concomitantly with plaque and screws through anterior access in cervical degenerative diseases on a single anatomical level.

Postura de trabalho relacionada com as dores na coluna vertebral em trabalhadores de uma indústria de alimentos: estudo de caso

This study has as main objective to identify the complains occurrences about pain in the spine segments, that are related to work standing posture, adopted by the collaborators in the production section of a food industry, in the city of Marília São Paulo state. A descriptive research and studying case was made, using 30 employees as a sample. It was used as methodological procedure, a questionnaire to obtain information on professional and personal data, posture to remain standing, the most uncomfortable postures in the work environment (signed by the form of Ranney, 2000) and pain (pointed out by Corllet and Manenica Diagram, 1980). It was also used the Nordic questionnaire (Kuorioka et al.,1986), validated in the Brazilian culture by Barros e Alexandre (2003) and adapted for the study, the direct evaluation and, a direct observation was made in the production work, a posture analysis using the OWAS Method. It was noticed that the posture of standing up is adopted during work, and 73.3% of the people that was interviewed said that they felt tired in consequence of this posture, especially when associated with trunk twists, trunk inclination and elevation of their arms above their heads. Most complains regarding pain through their bodies, by Corllet e Manenica (1980) pointed to the lumbar region, followed in the dorsal area and legs and in the neck area, shoulders and right thigh. The adapted Nordic questionnaire reveled the lumbar area, in 10 interviewed people (33.3%) as the area mostaffected by musculoskeletal symptoms, next in the dorsal area, with five people interviewed (16.7%) and one of them (3.3%) felt pain in the cervical area, none reported pain in the hips area. The postural analysis was applied using OWAS method, and it was identified the postures that demanded more effort in the four levels of musculoskeletal injuries. As conclusion, the standing up posture and the asymmetric and incorrect movements are related to pain in the spine, mostly in the lumbar area.

Human papillomavirus genotypes distribution in 175 invasive cervical cancer cases from Brazil

Abstract Background Invasive cervical cancer is the second most common malignant tumor affecting Brazilian women. Knowledge on Human Papillomavirus (HPV) genotypes in invasive cervical cancer cases is crucial to guide the introduction and further evaluate the impact of new preventive strategies based on HPV. We aimed to provide updated comprehensive data about the HPV types’ distribution in patients with invasive cervical cancer. Methods Fresh tumor tissue samples of histologically confirmed invasive cervical cancer were collected from 175 women attending two cancer reference hospitals from São Paulo State: ICESP and Hospital de Câncer de Barretos. HPV detection and genotyping were performed by the Linear Array HPV Genotyping Test (Roche Molecular Diagnostics, Pleasanton,USA). Results 170 out of 172 valid samples (99%) were HPV DNA positive. The most frequent types were HPV16 (77.6%), HPV18 (12.3%), HPV31 (8.8%), HPV33 (7.1%) and HPV35 (5.9%). Most infections (75%) were caused by individual HPV types. Women with adenocarcinoma were not younger than those with squamous cell carcinoma, as well, as women infected with HPV33 were older than those infected by other HPV types. Some differences between results obtained in the two hospitals were observed: higher overall prevalence of HPV16, absence of single infection by HPV31 and HPV45 was verified in HC-Barretos in comparison to ICESP patients. Conclusions To our knowledge, this is one of the largest studies made with fresh tumor tissues of invasive cervical cancer cases in Brazil. This study depicted a distinct HPV genotype distribution between two centers that may reflect the local epidemiology of HPV transmission among these populations. Due to the impact of these findings on cervical cancer preventive strategies, extension of this investigation to routine screening populations is warranted.

Avaliação das técnicas cirúrgicas para tratamento da mielorradiculopatia espondilótica cervical

OBJETIVO: Avaliar a eficácia do tratamento cirúrgico da mielorradiculopatia espondilótica cervical na produção de melhora neurológica pós-operatória, aferida em pontos pela escala da JOA e taxa de recuperação e as complicações do tratamento. MÉTODOS: Análise dos prontuários e os exames de imagem de 200 indivíduos submetidos a tratamento cirúrgico da mielorradiculopatia cervical no HC-FMUSP, no período de janeiro de 1993 a janeiro de 2007. A avaliação clínica foi quantificada pela escala da JOA, com média de segmento de 06 anos e 08 meses. RESULTADOS: Evidenciou-se melhora neurológica pós-operatória nas vias anterior e posterior, exceto nas laminectomias sem fusão, onde houve piora neurológica tardia. A via anterior mostrou um significante maior índice de complicações, relacionados a déficit de fusão intervertebral, deslocamento de enxerto, síndrome de disco adjacente, disfonia, disfagia, o mau posicionamento de enxerto e placas, lesão de raiz nervosa e significativo maior índice de re-intervenção cirúrgica. Na via posterior maior ocorrência de instabilidade em cifose pós-operatória na laminectomia, não sendo observada na laminoplastia, esta última com índices semelhantes aos encontrados na via anterior. Não houve melhora da dor axial nas laminoplastias e houve piora nas laminectomias, enquanto que nas discectomias e corpectomias houve significativa melhora do sintoma. CONCLUSÃO: As vias anterior e posterior foram eficazes em produzir melhora neurológica, exceto as laminectomias sem fusão. A via anterior produziu mais complicações, mas trata melhor a dor.

Fatores prognósticos associados ao tratamento cirúrgico da mielorradiculopatia espondilótica cervical

OBJETIVO: Identificar os fatores clínicos dos indivíduos, fatores sociais, ambientais e dos exames de imagem que se correlacionam ao resultado final de melhora neurológica em pacientes submetidos ao tratamento cirúrgico da mielopatia espondilótica cervical. MÉTODOS: A avaliação clínica foi quantificada pela escala deficitária da JOA. Analisamos 200 casos de mielorradiculopatia cervical, operados no HC-FMUSP, no período de janeiro de 1993 a janeiro de 2007. A média de segmento foi de 06 anos e 08 meses. A análise radiológica foi baseada nos critérios de instabilidade de White e scala de Kellgren. RESULTADOS: Em 80% houve melhora, 14% estabilização e em 6% piora do quadro neurológico. A piora neurológica não foi associada com nenhum fator clínico, ambiental ou de imagem. A melhora neurológica foi diretamente proporcional a menor idade na cirurgia, ausência de co-morbidade, sinal de Hoffman, atrofia muscular, hipersinal medular na RNM, menor período de evolução pré-operatório, melhor status neurológico pré-operatório e inversamente proporcional ao diâmetro AP do canal medular e multiplicidade de compressões. Identificou-se associação com o tabagismo. Mais de 70 anos, evolução superior a 24 meses, atrofia muscular, pontuação JOA igual ou inferior a sete pontos e diâmetro AP do canal inferior ou igual a seis mm não foram associado à melhora.

Prognostic Value Of Dna And Mrna E6/e7 Of Human Papillomavirus In The Evolution Of Cervical Intraepithelial Neoplasia Grade 2.

This study aimed at evaluating whether human papillomavirus (HPV) groups and E6/E7 mRNA of HPV 16, 18, 31, 33, and 45 are prognostic of cervical intraepithelial neoplasia (CIN) 2 outcome in women with a cervical smear showing a low-grade squamous intraepithelial lesion (LSIL). This cohort study included women with biopsy-confirmed CIN 2 who were followed up for 12 months, with cervical smear and colposcopy performed every three months. Women with a negative or low-risk HPV status showed 100% CIN 2 regression. The CIN 2 regression rates at the 12-month follow-up were 69.4% for women with alpha-9 HPV versus 91.7% for other HPV species or HPV-negative status (P < 0.05). For women with HPV 16, the CIN 2 regression rate at the 12-month follow-up was 61.4% versus 89.5% for other HPV types or HPV-negative status (P < 0.05). The CIN 2 regression rate was 68.3% for women who tested positive for HPV E6/E7 mRNA versus 82.0% for the negative results, but this difference was not statistically significant. The expectant management for women with biopsy-confirmed CIN 2 and previous cytological tests showing LSIL exhibited a very high rate of spontaneous regression. HPV 16 is associated with a higher CIN 2 progression rate than other HPV infections. HPV E6/E7 mRNA is not a prognostic marker of the CIN 2 clinical outcome, although this analysis cannot be considered conclusive. Given the small sample size, this study could be considered a pilot for future larger studies on the role of predictive markers of CIN 2 evolution.

[why Does The Prevalence Of Cytopathological Results Of Cervical Cancer Screening Can Vary Significantly Between Two Regions Of Brazil?].

To analyze the prevalence of cervical cytopathological results for the screening of cervical cancer with regard to women's age and time since the last examination in Maceió and Rio de Janeiro, Brazil, among those assisted by the Brazilian Unified Health System. Cervical cytopathological results available in the Information System of Cervical Cancer Screening for the year 2011 were analyzed, corresponding to 206,550 for Rio de Janeiro and 45,243 for Maceió. In Rio de Janeiro, examination at one and two year intervals predominated, while in Maceió examination at one and three year intervals had a higher predominance. Women who underwent cervical smear screening in Maceió were older than those in Rio de Janeiro. The prevalence of invasive squamous cell carcinoma was similar for the two cities, but all the other results presented a higher prevalence in Rio de Janeiro: ASCUS (PR=5.32; 95%CI 4.66-6.07); ASCH (PR=4.27; 95%CI 3.15-5.78); atypical glandular cells (PR=10.02; 95%CI 5.66-17.76); low-grade squamous intraepithelial lesions (PR=6.10; 95%CI 5.27-7.07); high-grade squamous intraepithelial lesions (PR=8.90; 95%CI 6.50-12.18) and adenocarcinoma (PR=3.00; 95%CI 1.21-7.44). The rate of unsatisfactory cervical samples was two times higher in Maceió and that of rejected samples for analysis was five times higher in Maceió when compared to Rio de Janeiro. The prevalence rates of altered cervical cytopathological results was significantly higher in Rio de Janeiro than in Maceió. There is no objective information that may justify this difference. One hypothesis is that there may be a difference in the diagnostic performance of the cervical cancer screening, which could be related to the quality of the Pap smear. Thus, these findings suggest that it would be necessary to perform this evaluation at national level, with emphasis on the performance of cervical cancer screening in order to improve the effectiveness of cervical cancer control.

Cervical Spine Involvement In Rheumatoid Arthritis--a Systematic Review.

Rheumatoid arthritis (RA) is a systemic chronic inflammatory disorder that can compromise the cervical spine in up to 80% of the cases. The most common radiological presentations of cervical involvement are atlantoaxial subluxation (AAS), cranial settling and subaxial subluxation (SAS). We performed a systematic review in the PubMed Database of articles published later 2005 to evaluate the prevalence, progression and risk factors for cervical spine involvement in RA patients. Articles were classified according to their level of evidence. Our literature review reported a wide range in the prevalence of cervical spine disease, probably explained by the different studied populations and disease characteristics. Uncontrolled RA is probably the main risk factor for developing a spinal instability. Adequate treatment with DMARD and BA can prevent development of cervical instabilities but did not avoid progression of a pre-existing injury. MRI is the best radiological method for diagnosis cervical spine involvement. AAS is the most common form of RA. Long term radiological follow-up is necessary to diagnosis patients with late instabilities and monitoring progression of diagnosed injuries.

Cervical Injuries Scored According To The Subaxial Injury Classification System: An Analysis Of The Literature.

The Subaxial Injury Classification (SLIC) system and severity score has been developed to help surgeons in the decision-making process of treatment of subaxial cervical spine injuries. A detailed description of all potential scored injures of the SLIC is lacking. We performed a systematic review in the PubMed database from 2007 to 2014 to describe the relationship between the scored injuries in the SLIC and their eventual treatment according to the system score. Patients with an SLIC of 1-3 points (conservative treatment) are neurologically intact with the spinous process, laminar or small facet fractures. Patients with compression and burst fractures who are neurologically intact are also treated nonsurgically. Patients with an SLIC of 4 points may have an incomplete spinal cord injury such as a central cord syndrome, compression injuries with incomplete neurologic deficits and burst fractures with complete neurologic deficits. SLIC of 5-10 points includes distraction and rotational injuries, traumatic disc herniation in the setting of a neurological deficit and burst fractures with an incomplete neurologic deficit. The SLIC injury severity score can help surgeons guide fracture treatment. Knowledge of the potential scored injures and their relationships with the SLIC are of paramount importance for spine surgeons who treated subaxial cervical spine injuries.

Metastatic Cervical Carcinoma Of The Jaw Presenting As Periapical Disease.

To present a case report of a metastasis from cervical cancer to the maxilla, which was misdiagnosed as periapical disease and to caution clinicians that metastases could have a disguised clinical presentation that must be taken into account in the differential diagnosis of periapical disease in oncologic patients. Although metastatic tumours of the jaws are uncommon, they may mimic benign inflammatory processes and reactive lesions. The ability of metastatic lesions to mimic periapical disease is discussed and a brief review of the literature is presented, emphasizing the importance of correct diagnosis to prevent delay in diagnosing cancer. Attention should therefore be given to the patient's medical history, especially of those with a previous history of cancer, and all dental practitioners should be aware of the possibility of metastases that may be confused with periapical disease. Finally, endodontists are well placed to recognize malignant and metastatic oral lesions during the initial clinical stages, given that their treatments are usually based on frequent dental appointments and long-term follow-ups.

Pain Intensity And Cervical Range Of Motion In Women With Myofascial Pain Treated With Acupuncture And Electroacupuncture: A Double-blinded, Randomized Clinical Trial.

Acupuncture stimulates points on the body, influencing the perception of myofascial pain or altering physiologic functions. The aim was to evaluate the effect of electroacupuncture (EAC) and acupuncture (AC) for myofascial pain of the upper trapezius and cervical range of motion, using SHAM acupuncture as control. Sixty women presenting at least one trigger point at the upper trapezius and local or referred pain for more than six months were randomized into EAC, AC, and SHAM groups. Eight sessions were scheduled and a follow-up was conducted after 28 days. The Visual Analog Scale assessed the intensity of local and general pain. A fleximeter assessed cervical movements. Data were analyzed using paired t or Wilcoxon's tests, ANOVA or Friedman or Kruskal-Wallis tests and Pearson's correlation (α=0.05). There was reduction in general pain in the EAC and AC groups after eight sessions (P<0.001). A significant decrease in pain intensity occurred for the right trapezius in all groups and for the left trapezius in the EAC and AC groups. Intergroup comparisons showed improvement in general pain in the EAC and AC groups and in local pain intensity in the EAC group (P<0.05), which showed an increase in left rotation (P=0.049). The AC group showed increases in inclination (P=0.005) sustained until follow-up and rotation to the right (P=0.032). EAC and AC were effective in reducing the pain intensity compared with SHAM. EAC was better than AC for local pain relief. These treatments can assist in increasing cervical range of motion, albeit subtly.
