ABSTRACT
Abstract Introduction Mucosal contact headache is a referred pain that arises from contact between the nasal septum and the lateral nasal wall. Evidence supports the role of substance P in a contact headache such that release of substance P from sensory nerve endings causes inflammation and allergy. Objectives This study aimed to determine possible differences in substance P levels in inferior turbinate hypertrophy creating a contact headache. Methods 28 patients who had contact headaches (study group) and 16 volunteers with no complaints were included in the study. Substance P levels in the inferior turbinate tissue samples were quantified using a commercially available substance P EIA kit. Results In the study group average substance P levels were 2.65 ± 0.27 pg/mg tissue (range: 0.61-5.44) and in the control group it was 1.77 ± 0.27 pg/mg tissue (range: 0.11-4.35). The difference was statistically significant between the two groups (p = 0.0215). Average preoperative headache group visual analog scale scores was 5.93 ± 0.38 (2-9) and the turbinate volume was 6.56 ± 0.35 cm3 (3.50-10.30). The control group turbinate volume was 4.71 ± 0.39 cm3 (2.50-7.70). We found a correlation between the visual analog scale scores and substance P levels such that substance P levels were higher in visual analog scale scores above 5 (p = 0.001). Conclusion This study demonstrates the relationship between intranasal contact headaches and increased mucosal substance P levels. We also found that there is no correlation with substance P levels and volume of the inferior turbinate.
Resumo Introdução A cefaleia por ponto de contato da mucosa é uma dor direcionada que surge do contato entre o septo nasal e a parede nasal lateral. Evidências corroboram o papel da substância P na cefaleia de contato, de tal forma que a liberação da mesma a partir de terminações nervosas sensoriais possa causar inflamação e alergia. Objetivo Determinar possíveis diferenças nos níveis da substância P na hipertrofia de conchas inferiores em relação à cefaleia de contato. Método Foram incluídos no estudo 28 pacientes que apresentaram cefaleia por ponto de contato (Grupo Estudo) e 16 voluntários sem queixas. Os níveis de substância P nas amostras de tecido da concha inferior foram quantificados com um kit substância P EIA, comercialmente disponível. Resultados No grupo do estudo, os níveis médios de substância P foram 2,65 ± 0,27 pg/mg de tecido (variação: 0,61-5,44) e no grupo controle foram de 1,77 ± 0,27 pg/mg de tecido (variação: 0,11-4,35) e a diferença foi estatisticamente significante entre os dois grupos (p = 0,0215). O escore médio da escala visual analógica do grupo de cefaleia pré-operatória foi de 5,93 ± 0,38 (2-9) e o volume das conchas foi de 6,56 ± 0,35 cm3 (3,50-10,30). O volume da concha do grupo controle foi de 4,71 ± 0,39 cm3 (2,50 ± 7,70). Encontramos uma correlação entre o escore da escala visual analógica e os níveis de substância P, de modo que os níveis de substância P foram maiores nos escores da escala visual analógica acima de 5 (p = 0,001). Conclusão Este estudo demonstra a relação entre cefaleias por contato intranasais e níveis aumentados de substância P nas mucosas. Também observamos que não há correlação com os níveis de substância P e o volume da concha inferior.

PURPOSE: To analyze the contact mechanics of the femoral component and polyethylene of the Low Contact Stress rotating platform (LCS-RP) in nonweight bearing and weight bearing conditions using full flexion lateral radiographs. MATERIALS AND METHODS: From May 2009 to December 2013, 58 knees in 41 patients diagnosed with osteoarthritis and treated with total knee arthroplasty (TKA) were included in this study. TKA was performed using an LCS-RP knee prosthesis. Full flexion lateral radiographs in both weight bearing and nonweight bearing condition were taken at least one month postoperatively (average, 28.8 months). Translation of femoral component was determined by the contact point between the femoral component and polyethylene. Maximum flexion was measured as the angle between the lines drawn at the midpoint of the femur and tibia. RESULTS: Posterior shift of the contact point in LCS-RP TKA was observed under weight bearing condition, which resulted in deeper flexion compared to LCS-RP TKA under nonweight bearing condition. CONCLUSIONS: In the LCS-RP TKA, the contact point between the femoral component and polyethylene moved posteriorly under weight bearing condition, and the joint was more congruent and maximum flexion increased with weight bearing.

Rhinogenic headache may be defined as a headache directly caused by pathology within the nose or paranasal sinuses. Rhinogenic headache is a controversial, but distinct type of headache that has received an increased amount of attention in the literature over the past twenty years. The International Classification of Headache Disorders, 3rd edition has been released by the 'International Headache Society' in May 2013. As this version is based on a large body of research on headache, in contrast to previous editions that were mostly based on opinion of experts, it is being considered as a major step forward in the diagnosis and management of headache. The International Headache Society presented the diagnostic criteria of rhinogenic headache divided into three types: Headache Attributed to Acute Rhinosinusitis, Headache Attributed to Chronic or Recurring Rhinosinusitis, Headache Attributed to Disorder of the Nasal Mucosa, Turbinates or Septum. We herein present the salient features of the new classification, which are likely to be of interest to the rhinologist. In addition, I review the evidence that intranasal mucosal contact points cause facial pain or headache and present the important points to consider in diagnosis and treatment of mucosal contact point headache.

Headaches attributed to disorders of the sinonasal region make their diagnosis and treatment sometimes challenging. Contact point between opposing mucosal surfaces in the nasal cavity can cause headache by a mechanism of referred pain in the distribution of trigeminal nerve. The most common anatomic abnormality of intranasal contact point is the diverse pattern of septal deviation in association with turbinate deformity or hypertrophy. In the absence of other pathological findings, the evaluation for intranasal contact points should be considered. We herein report that a patient, suffering from headache and periorbital pain refractory to medical treatment, experienced a complete abolition of pain after surgical correction of mucosal contact point in the nasal cavity.

One of the most challenging task in closing anterior diastema is avoiding "black triangle" between the teeth. This paper reports a case that the closure of diastema in anterior teeth could be successfully accomplished using direct adhesive restorations and gingival recontouring. The traditional technique using Mylar strip was modified to increase the emergence profile with natural contours at the gingival-tooth interface. Mylar strip was extended out of the sulcus by approximately 1 mm high from the gingival margin, and a small cotton pellet was used to provide the emergence contour. This modified approach is acceptable for the clinical situation.

ABSTRACT
En la actualidad existe una gran demanda por restauraciones con un aspecto natural en las zonas que requieren más estética, debido a esto la odontología moderna no se limita a restaurar la estructura dental dañada o perdida, sino que además se basa en la reconstrucción de la arquitectura de los tejidos blandos adyacentes, de manera que éstos constituyen un componente muy importante en la estética de la sonrisa. La papila interproximal es considerada un elemento esencial de los dientes anteriores y posteriores. La ausencia de ésta estructura, puede originar deformidades estéticas, problemas fonéticos y acumulación de alimentos. El objetivo de la presente revisión es dar a conocer la influencia de la distancia vertical y horizontal en el momento de realizar restauraciones entre implantes contiguos, diente e implante, y dientes adyacentes y su incidencia en la neoformación de la papila. Esto quiere decir, que previo al tratamiento restaurador que se esté planificando, es esencial un buen análisis radiográfico y clínico del paciente con el fin de evaluar el nivel de la papila y pronosticar en que porcentaje obtendremos su neoformación, tomando en cuenta la distancia de ésta con la cresta ósea, y la ubicación el punto de contacto
At the present time there is an increasing demand for natural restoration in the esthetic zone. Due to this, there is not limited for modern dentistry to restore dental structure damage, but also the reconstruction of adjacent soft tissue, which constitute a very important component in esthetic smile. The interproximal papilla is considered an essential element in anterior and posterior teeth. The absence of this structure will originate esthetic deformities, phonetic problems and food accumulation. The goal of the present revision is to present the influence in horizontal and vertical distance at the moment to carry out restoration among contiguous implant, teeth and implants, adjacent tooth and incidence in papilla neoformation. This means, that previous to the planiffing treatment is essential a patients clinical and radiographic analysis to evaluate papilla level and neoformation percentage to prognosticate the distance from contact point to the crest of bone

ABSTRACT
In order to find a point of contact between eastern and western medicine, the so called _??__??__??__??_ (carriers of every function of the body) were claasified into seven functional systems, such as the respiratory system etc., and assigned to seven corresponding anatomical “organs and tissues”, such as the heart etc. However, the meaning of _??__??_ in traditional eastern medicine does not equate with “organs and tissues” of the “Anatomy”. In this report, in order to find a correspondence of pathological changes and fuctional alterations, all the accessory changes among a total of 92 autopsy cases, who had diseases of the brain, were classified into seven systems, and an assessment of each frequency was performed by the statistical <i>X</i><sup>2</sup> method. The resets we obtained point to the accuracy of the insight of ancient Chinese traditional medicine, _??__??__??__??_.
