Restorative Rehabilitation of a Patient with Generalized Non-Carious Cervical Lesions: Case Report / Rehabilitación restaurativa de un paciente con lesiones cervicales no-cariosas generalizadas: Reporte de un caso

ABSTRACT Non-Carious Cervical Lesions (NCCL) are a current problem of multifactorial origin that is associated with the loss of vertical occlusal dimension, hypersensitivity, loss of teeth, fractures, and many other pathologies that affect the masticatory function of the oral cavity. Identification of the etiological factors of NCCL comprises a key piece for the solution of the problem. Based on clinical scientific evidence related with the diagnosis, a restorative treatment must be planned according to the loss of dental structure in order to return function and aesthetics. The purpose of this case report was to describe a 54-year-old male patient who was diagnosed with generalized NCCL combined with occlusal vertical dimension loss. The protocol of the treatment process is described.

RESUMEN Las lesiones cervicales no cariosas (LCNC) son una problemática actual de origen multifactorial, la cual se ve asociada a la pérdida de dimensión vertical oclusal, hipersensibilidad, pérdida de dientes, fracturas y muchas otras patologías que afectan la función masticatoria de la cavidad bucal. La identificación de los factores etiológicos de las LCNC son piezas claves para la solución del problema. Basados en la evidencia científica clínica relacionado con el diagnóstico, se debe planificar un plan de tratamiento restaurativo que depende de la pérdida de la estructura dentaria para devolver la función y estética. El objetivo de este reporte de caso es describir a un paciente masculino de 54 años a quien se le diagnosticó LCNC generalizadas combinado con una pérdida de dimensión vertical oclusal. El protocolo de plan de tratamiento es descrito paso a paso.

Estudo das características clínicas, comportamentais e dos parâmetros salivares de pacientes portadores de lesões cervicais não cariosas e um grupo controle / Study of clinical, behavioral and salivary parameters in patients with non-carious cervical lesions and a control group

A saliva é um fluido biológico com importante papel nos fenômenos que ocorrem na cavidade bucal. O efeito da sua composição sobre as perdas de estruturas dentais de origem não cariosa, como o desgaste dental, tem sido estudado. No entanto, há conflitos nos resultados apresentados por esses estudos, mostrando uma dificuldade em identificar os fatores salivares que possam proteger ou intensificar a evolução do processo. Assim, o presente estudo se propôs a analisar as características clínicas, comportamentais e de alguns parâmetros salivares em dois grupos experimentais: pacientes que apresentam lesões cervicais não cariosas (LCNCs) (n=20) e um grupo controle (n=20). Foram coletados dados clínicos e comportamentais através de um exame clínico e de uma entrevista, a seguir amostras de saliva estimulada e não-estimulada foram coletadas e analisados: pH, capacidade tampão, fluxo salivar, concentração de proteínas totais, atividade da amilase salivar, concentração de ureia salivar e a concentração dos íons sódio, fósforo, potássio, magnésio e cálcio. A capacidade tampão foi medida pela titulação da saliva com uma solução de HCL 0,01N; o fluxo salivar se deu pela relação entre o volume de saliva e o tempo de coleta (ml/min); as concentrações de proteínas totais, ureia e a atividade da amilase foram determinadas por método colorimétrico; as concentrações dos íons cálcio, fósforo, magnésio, potássio e sódio foram determinadas por espectrometria de emissão óptica com plasma acoplado indutivamente (ICP-OES).

Os resultados foram submetidos aos testes Qui-quadrado, teste t e Mann-Whitney (p<0,05). As características relacionadas aos hábitos de higiene dental, dieta ácida, hábitos parafuncionais, presença de distúrbios gástricos, secura bucal e prévio tratamento periodontal, não mostraram relação com a presença de lesões cervicais não cariosas. Os pacientes portadores de LCNCs se queixaram mais de sensibilidade dental (p=0,0014). Foi observado um maior número de lesões cervicais de pequena profundidade (79%), em formato de cunha (72%), apresentando hipersensibilidade dentinária (HD) (86%), localizados nos dentes posteriores (88,18%) e na maxila (66,14%), sendo os pré-molares os dentes mais afetados (56,69%). Os níveis de cálcio na saliva não-estimulada do grupo de pacientes com LCNCs foi significativamente maior em relação ao controle (p=0,041). A concentração de potássio na saliva estimulada foi significativamente maior no grupo controle (p=0,028). As variáveis fluxo salivar, pH, capacidade tampão, concentração de proteínas totais, ureia, amilase, sódio, magnésio e fósforo não mostraram diferenças estatisticamente significativas entre os dois grupos. Conclui-se que os fatores comportamentais não interferiram no aparecimento das lesões cervicais não cariosas. As LCNCs são pouco profundas, em formato de cunha, acometem mais dentes superiores e pré-molares e são acompanhadas de HD. As concentrações de cálcio e potássio podem interferir na formação das LCNCs.

Saliva is a biological fluid with an important role in the phenomena that occur in the oral cavity. The effect of salivary composition in loss of tooth structure with no carious origin, such as tooth wear, has been studied. However, there are conflicts in the results presented by studies showing a difficulty in identifying the salivary factors which may protect or intensify the development of tooth wear process. The aim of this study was to analyze the clinical, behavioral and some salivary parameters into two groups: patients with non-carious cervical lesions (NCCLs) (n=20) and a control group (n=20). Clinical and behavioral data were collected through a clinical examination and an interview. Saliva samples stimulated and unstimulated were collected and analyzed: pH, buffer capacity, flow rate, total protein, amylase activity, urea, sodium, phosphorus, potassium, magnesium and calcium. The buffer capacity was measured by titration of saliva samples using 0.01N HCl solution; flow rate was the relationship between the volume of saliva and the collection time (ml/min); the concentrations of total protein, urea and amylase activity were determined by colorimetric method; concentrations of calcium, phosphorus, magnesium, potassium and sodium were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The results were tested to the chi-square test, t-test and Mann-Whitney U test (p<0.05).

The characteristics related to dental hygiene, acidic diet, parafunctional habits, presence of gastric disorders, dry mouth, and previous periodontal treatment did not show relationship to the presence of non-carious cervical lesions. Patients with non-carious cervical lesions complained over tooth sensitivity (p=0.0014). It observed an increased number of cervical lesions small depth (79%), wedge-shaped (72%), with dentin hypersensitivity (86%), located the posterior teeth (88,18%) and maxilla (66,14%), the premolars being the most affected teeth (56,69%). The concentration of calcium in unstimulated saliva of patients with NCCLs was significantly higher compared to control (p=0.041). The concentration of potassium was significantly higher in stimulated saliva in the control group (p=0.028). The results flow rate, pH, buffer capacity, total protein, urea, amylase, sodium, magnesium and phosphorus showed no significant differences between the two groups. It is concluded that behavioral factors do not interfere in the presence of non-carious cervical lesions. The NCCLs are shallow, wedge-shaped, affecting more maxilla and premolars and are accompanied by DH. The calcium and potassium concentrations may interfere with the formation of NCCLs.

Management of twenty patients with neck trauma in Khartoum ENT Hospital

Neck trauma is a great surgical challenge, because there are multi organ and systems involved. To study the clinical presentation, management and outcome of twenty patients presented to Khartoum ENT Hospital with neck trauma. This is a prospective study conducted in Khartoum ENT Hospital, Sudan during the period 1998- 2008. A total number of 20 patients presented to our unit with neck trauma were included in the study. All patients were admitted to the hospital, assessed and managed according to the magnitude of trauma. The age varied from 5 to 40years, with mean age [ +/- SD] 28 years [ +/- 9]. Male to female ratio was 2:1. Most of the patients presented to the Hospital between 1-6 hours after trauma. The mechanism of neck trauma was blunt trauma in 16[80%] patients and penetrating wound in 4[20%] patients. The distribution of injuries in neck zones were 17[85%] patients in zone two, 2[10%] patients in zone three and one patient in zone one. Tracheal injury and pharyngeal injury were seen in 4[20%] patients each, laryngeal injury in 5[25%] patients, and salivary gland injury in 1[5%] patient. Surgical exploration and tracheostomy were done in 4[20%] patients. tracheostomy alone was performed in 7[35%] patients with blunt trauma. Conservative management without surgical intervention was done in 9[45%] patients. The common complications in this study were vocal cord paralysis and subglottic stenosis in 2[10%] patients each, while surgical emphysema and haemothorax was seen in one patient. Zone two injures were the commonest injuries. Early presentation and proper management of patients with neck trauma carry good prognosis.

Hematoma retrofaríngeo secundário a pequeno trauma contuso no pescoço: relato de caso / Retropharyngeal hematoma secondary to minor blunt neck trauma: case report / Hematoma retrofaríngeo secundario a un pequeño trauma contundente en el cuello: relato de caso

JUSTIFICATIVA E OBJETIVOS: O desenvolvimento de hematoma retrofaríngeo após trauma contuso é uma ocorrência rara. Porém, uma lesão ocupando espaço nessa área pode ser fatal, o que exige rápida avaliação e tratamento. Esse tipo de hematoma é clinicamente importante devido à proximidade entre o espaço retrofaríngeo e a via aérea superior. Qualquer edema nesse espaço pode causar uma protuberância da parede posterior da faringe de encontro às vias aéreas e obstruí-las. RELATO DE CASO: Paciente do sexo feminino, 86 anos, que caiu de uma altura de 1,5 m e bateu o pescoço na escada, foi admitida em nosso Departamento de Traumatologia. Tomografia computadorizada e radiografia dos tecidos moles do pescoço foram feitas e mostraram uma grande massa retrofaríngea que se estendia da base do crânio até o nível dos pulmões. A paciente ficou em observação e o tamanho do hematoma diminuiu espontaneamente nos sete dias subsequentes; contudo, devido a uma infecção pulmonar, a paciente foi a óbito no décimo dia. Este relato enfatiza que a drenagem precoce do hematoma retrofaríngeo poderia ter sido considerada neste caso. Embora seja de ocorrência rara, o hematoma retrofaríngeo é um problema que pode ser encontrado em serviços de emergência.

BACKGROUND AND OBJECTIVES: The development of a retropharyngeal hematoma following a blunt trauma is a rare occurrence. However, a spaceoccupying lesion in this area can be life-threatening and requires rapid assessment and treatment. This is clinically important because of the close proximity of the retropharyngeal space to the upper airway. Any swelling in the the posterior pharyngeal space may prompt it to bulge anteriorly into the airway and cause its obstruction. CASE REPORT: A 86-year-old woman fell from a height of 1.5 m and hit her neck on stairs and was admitted to our trauma department. A computerized tomography scan and a lateral neck x-ray to observe the soft tissue revealed a large retropharyngeal mass extending from the base of the skull down to the level of the lung. The patient was kept under observation and the hematoma reduced spontaneously in the following seven days although the patient died on the tenth day from pulmonary infection. The report emphasizes that early drainage of a retropharyngeal hematoma should be considered in similar cases. Although rarely encountered, retropharyngeal hematoma is a problem that can be faced in an emergency department.

JUSTIFICATIVA Y OBJETIVOS: El desarrollo del hematoma retrofaríngeo posterior al trauma contundente es un hecho raro. Sin embargo, una lesión que ocupa un espacio en esa área puede ser fatal, lo que exige una rápida evaluación y el tratamiento adecuado. Ese tipo de hematoma es clínicamente importante debido a la cercanía entre el espacio retrofaríngeo y la vía aérea superior. Cualquier hinchazón en ese espacio puede causar una protuberancia de la pared posterior de la faringe contra las vías aéreas y obstruirlas. RELATO DE CASO: Paciente del sexo femenino, de 86 años, que se cayó de una altura de 1,5 m y se dio con la escalera en el cuello. Fue admitida en nuestro Departamento de Traumatología. Se realizaron la tomografía computadorizada y la radiografía de los tejidos suaves del cuello, lo que arrojó una gran masa retrofaríngea que se extendía desde la base del cráneo hasta el nivel de los pulmones. La paciente permaneció en observación y el tamaño del hematoma se redujo espontáneamente en los siete días posteriores; sin embargo, y debido a una infección pulmonar, la paciente falleció al décimo día. Ese relato nos muestra que el drenaje rápido del hematoma retrofaríngeo podría haber sido considerado en ese caso. Y aunque sea de una baja incidencia, el hematoma retrofaríngeo es un problema que puede ser encontrado en los servicios de emergencia.

Trauma transfixante: relato de caso / Transfixing traum: case report

Atualmente os traumas por arma de fogo estão cada vez mais comuns, principalmente na população com idadeprodutiva. Lesões cervicais por esse mecanismo são de grande importância por sua morbimortalidade. Suspeitardo diagnóstico e dar o suporte adequado é de extrema importância para salvar a vida do paciente. Nosso objetivo é descrever um caso de ferimento transfixante por PAF em região cervical, com fístula artériovenosa, que obteve um bom desfecho.

Nowadays traumas caused by firearms are more and more common, particularly among working age population. Cervical lesions caused by this mechanism are ofgreat importance for its morbimortality. Distrusting the diagnosis and giving the appropriate support is of the utmost importance to save the life of the patient. Our objective is to describe a case of transfixing wound by PAF in a cervical region, with arteriovenous fistula, which had a good outcome.

Alterações eletrocardiológicas em pacientes com traumatismo da coluna cervical / Electrocardiographic alterations in patients with cervical spine injury

O coração é inervado pelo sistema simpático oriundo da coluna cervical e pelo sistema parassimpático do bulbo. Em casos de traumatismo da coluna cervical, ocorre falha do controle simpático do coração, predominando o sistema vagal, visto que este não é lesado. Esse predomínio é manifestado clinicamente por bradicardia e hipotensão. O presente trabalho objetivou analisar os achados eletrocardiográficos em pacientes jovens, sem antecedentes de cardiopatia, vítimas de traumatismo da coluna cervical. Foram analisados 35 pacientes (31 do sexo masculino e 4 do feminino). A idade média dos pacientes foi de 30+-8anos. Em 65 por cento dos casos, encontravam-se tetraplégicos. Houve predomínio de lesão entre C5 e C6 em 48 por cento dos casos. Os achados eletrocardiográficos apresentaram ritmo sinusal. A frequencia cardíaca média era de 74+-16 bpm e o eixo elétrico de 56+-17 graus. Em 28,17 por cento dos casos, o eletrocardiograma foi normal. Os achados anormais no eletrocardiograma foram: ondas T negativas na derivação V1 (17,18 por cento), bloqueio de ramo direito (36,46 por cento0, distúrbios de repolarização precoce (36,46 por cento) e ondas T amplas em V4 (9 por cento). A maioria desses achados é considerada fisiológica, não sendo eles tipos como predominantes em pacientes com traumatismo raquimedular cervical.

Dissecting aneurysm of the carotid artery after a minor neck trauma in a child: a case report

A case of dissecting aneurysm in a 5-year-old girl without a pre-existing predisposing factor is presented. Her clinical presentation in spite of being typical, did not progress to severe deficit. The diagnosis was achieved by 2D and 3D-TOF MRI studies after the indirect indications of the CT studies after the accident. This case study emphasizes the possible presentation s in children. This diagnosis in the pediatric age-group is difficult and is probably the reason for the very few cases reported

Vertebral artery dissection due to indirect neck trauma : an underrecognised entity.

Vertebral artery dissection is an important cause of brain stem stroke, especially in the young. Dissections of carotid and vertebral arteries in neck account for about 20% of strokes in young compared with 2.5% in the elderly. Three patients of vertebral artery dissection related to indirect neck trauma are described. The first patient developed the symptoms while dancing, the second after a trivial fall and the third while he was on a dental chair. None of them had a direct severe neck trauma or concomitant risk factor like hypertension, connective tissue disease or migraine. Clinical symptomatology was similar in all the patients and included occipito-nuchal pain, headache and brain stem dysfunction chiefly in the posterior inferior cerebellar artery (PICA) territory. One of the patients also had associated ischaemic myelopathy. MRA and DSA confirmed dissection in all with a predominant steno-occlusive picture. Cases of so called trivial neck movement/torsion related dissection have been described previously but have not received any major importance. Usually classified as 'spontaneous' or 'traumatic', there is a possible ambiguity in literature about appropriate terminology. We emphasise that a history of such subtle precipitating events be taken while diagnosing young patients with brain stem strokes, to recognise this clinical entity. Although mechanisms are not absolutely clear, yet there seems to be an important relationship between arterial dissection and neck movements or minor trauma.

Laryngotracheal transection in blunt trauma of the neck.

Laryngotracheal injuries are relatively rare following blunt trauma to the neck and chest but results in a high degree of morbidity and mortality. Complete disruption of the trachea is extremely rare and a systematic approach is needed for early diagnosis and management. The symptoms and physical signs do not necessarily correlate with the severity of injury as was observed in the presented cases here. An early diagnosis and surgical exploration is a must for a reasonably favourable outcome.

Intubación traqueal en paciente con luxofractura cervical inestable / Tracheal intubation in patients with unstable cervical luxofractures

Las fracturas alineadas y las luxofracturas cervicales están asociadas a un compromiso medular ya establecido o a un daño potencial de la médula. En el manejo agudo del politraumatizado, con un problema de vía aérea y/o un trastorno ventilatorio, se enfatiza la protección cervical en el momento de establecer una vía aérea definitiva (ya sea con intubación oro o naso-traqueal, o por vía quirúrgica), aún cuando no haya evidencias de fractura cervical o de lesión medular. En los casos de una fractura cervical inestable conocida, con o sin lesión medular asociada, en que existe indicación de una fijación quirúrgica, el manejo de la vía aérea y las alternativas para la intubación traqueal son importantes durante el acto anestésico. Se presenta un caso clínico de Luxofractura C5, con lesión medular parcial, sometido a una fijación por una vía anterior. Se analiza el manejo de la vía aérea y las diferentes técnicas de intubación traqueal en estos pacientes, enfatizando el uso de la intubación vigil, mediante fibra óptica, especialmente en los enfermos que están con inmovilización o tracción cervical
