RESUMO

La tendinitis calcificante del músculo largo del cuello es una patología subdiagnsoticada, de baja frecuencia, autolimitada. Se presenta clínicamente como una de las causas de odinofagia en la consulta médica. Se produce debido al depósito de cristales de hidroxiapatita en espacio retrofaríngeo, desencadenándose una respuesta inflamatoria local. En la TMLC el principal diagnóstico diferencial es el absceso retrofaríngeo, ya que puede presentarse clínicamente con odinofagia, disfagia , disminución de la movilidad del cuello y cervicalgia. En nuestro trabajo se analiza un caso clínico sobre dicha patología, en un hombre de 45 años; realizando un análisis de la sintomatología, diagnóstico y tratamiento de esta entidad.

Calcific tendinitis of the long neck muscle is an underdiagnosed, low frequency, self-limited pathology. It is clinically presented as one of the causes of odynophagia in the medical consultation. It occurs due to the deposit of hydroxyapatite crystals in the retropharyngeal space, triggering a local inflammatory response. On This patholgy, the main differential diagnosis is retropharyngeal abscess, since it can present clinically with odynophagia, dysphagia, decreased mobility of the neck, and neck pain. In our work, a clinical case of this pathology is analyzed, in a 45-year-old man; performing an analysis of the symptoms, diagnosis and treatment of this entity.

RESUMO

RESUMEN La tendinitis calcificante prevertebral es una patología benigna y poco frecuente, con una incidencia anual de 0,5 casos por cada 100.000 habitantes. Se presenta un caso de una paciente de 52 años que consultó por cervicalgia, odinofagia y disfonía de 5 días de evolución. Tras una exploración otorrinolaringológica completa se sospechó ocupación del espacio retrofaríngeo, confirmada con pruebas de imagen. Ante estos hallazgos y con la sospecha de absceso retrofaríngeo, se decidió ingreso hospitalario para tratamiento intravenoso. Por discordancia entre la clínica, la TC y los hallazgos analíticos, se solicitó RM cervical, cuya imagen hizo sospechar una tendinitis aguda calcificante del longísimo del cuello. En este trabajo se ha realizado una revisión de la sintomatología, el diagnóstico y el tratamiento de esta entidad. Consideramos importante sospecharla dentro del diagnóstico diferencial de la ocupación del espacio retrofaríngeo para evitar realizar procedimientos innecesarios.

ABSTRACT Prevertebral calcific tendinitis is a benign and infrequent pathology, with an annual incidence of 0.5 cases per 100,000 habitants. We report the case of a 52-year-old woman that presented with a 5-day history of cervicalgia, odynophagia and dysphonia. Otolaryngological examination and radiological images showed occupation of the retropharyngeal space. The patient was admitted to the hospital for intravenous treatment. A cervical MRI was requested, suggesting an acute calcific tendinitis of the longus colli muscles. The authors provide a discussion of the clinical findings, diagnosis and treatment of this condition. We consider it to be an important differential diagnosis of a retropharyngeal space occupation, in order to avoid unnecessary procedures.

RESUMO

RESUMEN La piomiositis es una infección bacteriana del músculo estriado, siendo extremadamente rara la afectación de la musculatura cervical. Se ha asociado en nuestro medio a enfermedades crónicas como la diabetes y a la inmunodepresión. Presentamos a un paciente de 67 años que acude al servicio de urgencias por tumoración laterocervical de rápido crecimiento, negando antecedentes de interés a excepción de diabetes mellitus tipo II. Se le realizó estudio de imagen con tomografía computarizada con contraste, observándose aumento de volumen del músculo esternocleidomastoideo izquierdo y se empezó tratamiento empírico con antibióticos endovenosos. Dada la evolución tórpida finalmente se realizó drenaje quirúrgico bajo anestesia general con mejoría de los parámetros clínicos y analíticos. La piomiositis de los músculos cervicales es muy rara (0,4%-1% de todos los casos) siendo el esternocleidomastoideo el músculo del cuello más frecuentemente afectado. La tomografía computarizada representa la prueba de imagen de elección, permitiendo un rápido diagnóstico llegando a poder diferenciar este cuadro de otros similares. Considerando que muchos de estos pacientes presentan comorbilidades asociadas y/o inmunosupresión, es de extrema importancia diagnosticarlos precozmente y empezar un tratamiento adecuado que dependerá del grado y extensión de la infección. A pesar de ser una entidad poco frecuente, su incidencia está en aumento en nuestro medio asociada a la infección por VIH y otras condiciones de inmunodepresión. Hay que tenerla en mente en el diagnóstico diferencial de las tumoraciones laterocervicales porque solo con una alta sospecha clínica se podrá llevar al cabo un diagnóstico precoz y un tratamiento adecuado.

ABSTRACT Pyomyositis is a bacterial infection of the striated muscle that may affect the cervical musculature in very few cases. In the occidental world it has been associated with chronic diseases as diabetes and immunosuppression. We present a 67 years old patient attended to the Emergency Department because of a laterocervical fast growth tumor, without an interesting clinical history with the exception of type II diabetes mellitus. A CT scan with contrast showed an increased volume in the left sternocleidomastoid muscle, so an empiric treatment with intravenous antibiotics was started. Because of a bad evolution we finally performed a surgical drainage of the abscess under general anesthesia with an improvement of symptoms and laboratory markers. The pyomyositis of cervical muscles is very rare (0.4-1% of all cases) and the sternocleidomastoid muscle is the most commonly affected cervical muscle. CT scan is the gold standard imaging technique, because it allows to diagnose this disease and rule out other similar entities. If we consider that many patients present with associated comorbidities and/ or immunosuppression, it's very important to perform a rapid diagnosis and to begin a correct treatment that depends on the grade and extension of the infection. Although polymyositis of the sternocleidomastoid muscle is rare, its incidence is increasing associated to HIV infection and other immunosuppressive conditions. We have to keep in mind this pathology in the differential diagnosis of laterocervical tumors because high clinical suspicion is necessary to make a rapid diagnosis and a correct treatment.

RESUMO

This article reports a self-strangulation suicide in which a double complex group of ligatures was used. Although similar cases have been referenced in forensic literature, this case is notable because of the unusual method used by the victim. A 61-year-old man was found in a locked room with a double elaborate ligature comprising six wire clothes hangers completely encircling the neck and a black rubber band in a double loop. Autopsy also documented parallel superficial cut lesions in proximal forearm interpreted as hesitation marks. It stresses the importance of characteristics such as analysis of number of ligatures, position of the knots, number of knots and turns of ligature marks and the absence of any defense and relevant internal injuries inherent to suicide ligature strangulation cases.

RESUMO

AIM: The aim of the present study was to perform a comparative analysis of occlusal contact points in children with and without signs and symptoms of Temporomandibular Disorders (TMD). STUDY DESIGN: Cross-sectional study. One hundred fifty children between 6 and 14 years of age were evaluated using the Helkimo questionnaire and a clinical exam. The occlusal contact points in each child were recorded during maximal intercuspation with the aid of carbon strips. Digital photographs were taken of the upper and lower arches before and after recording the occlusal contacts. The number of contact points between sides were compared and recorded on individual charts (occlusograms). STATISTICS: Student's t-test and Pearson's chi-square test were used for the statistical analysis, with the level of significance set at 0.05, which revealed no statistically significant differences between genders. The Student's t-test revealed a statistically significant difference in the mean number of occlusal contact points between the participants with and without TMD, with a higher number of contact points among those without TMD. There was no significant difference between sides. RESULTS The results of this study show a difference in the number of occlusal contact points in centric occlusion between children with and without TMD. CONCLUSION Regardless of the degree of severity, the number of occlusal contact points is lower among children with TMD.

RESUMO

A tendinite calcária aguda pré-vertebral é uma condição benigna e rara que apresenta calcificação das fibras do músculo longo do pescoço com reação inflamatória local, sendo esta uma das formas de apresentação menos frequentes da doença por deposição de hidroxiapatita de cálcio. Manifesta-se com dor cervical aguda e/ou odinofagia, podendo ser erroneamente diagnosticada como abscesso retrofaríngeo, espondilodiscite ou alteração decorrente de trauma. Os achados radiológicos na tendinite calcária pré-vertebral são patognomônicos. O conhecimento de tais achados é muito importante, pois o correto diagnóstico possibilita a resolução precoce dos sintomas e evita intervenções desnecessárias em um paciente que apresenta afecção com boa resposta ao tratamento conservador.

Acute calcific prevertebral tendinitis is a benign and rare condition that presents calcification of the superior oblique fibers of longus colli muscle with local inflammatory reaction. Such condition is one of the less common presentations of calcium hydroxyapatite deposition disease. Clinical signs are usually acute neck pain and odynophagia, and it may be misdiagnosed as retropharyngeal abscess, spondylodiscitis or traumatic injury. The imaging findings in calcific prevertebral tendinitis are pathognomonic. The knowledge of such findings is extremely important to avoid unnecessary interventions in a patient presenting a condition with a good response to conservative treatment.

RESUMO

We report a very unusual case of murder of a 4-year-old male white child who died of asphyxiation. Asphyxia occurred due to 3 factors: manual strangulation, hyperextension of the neck, and atlantoaxial subluxation. The offenses were carried out by a single assailant (the stepfather of the child) who strangled the child with his right hand, using his left hand to pull the hair of the child, forcing the head back and causing hyperextension of the neck, thereby dislocating the first and second cervical vertebrae.
