ABSTRACT

Objetivo: Este trabalho tem como propósito fornecer uma análise abrangente das características anatômicas, clínicas e radiográficas da Síndrome de Eagle, além de abordar os métodos de diagnóstico e estratégias terapêuticas. Materiais e métodos: Foi realizada uma busca por artigos científicos publicados no período de 2016 a 2024, utilizando as bases de dados Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) e Google Scholar. A coleta de artigos foi realizada nos idiomas inglês e português, utilizando as palavras-chave: "síndrome de eagle", "síndrome estiloide", "síndrome da artéria carótida", "estilalgia", "eagle syndrome", "styloid syndrome", "carotid artery syndrome" e "stylalgia". Conclusão: Os profissionais devem estar atentos à síndrome de Eagle em casos de dor unilateral ao realizar atividades como engolir, bocejar e chorar, sem causa aparente, especialmente em mulheres adultas que não encontram alívio com analgésicos. Devido à frequência de casos assintomáticos, a realização precoce de exames radiológicos desempenha um papel crucial na avaliação diagnóstica. É essencial que profissionais de Otorrinolaringologia, Neurologia e Odontologia estejam cientes dessa síndrome, pois está associada a uma significativa deterioração na qualidade de vida. (AU)


Objective: This work aims to provide a comprehensive analysis of the anatomical, clinical and radiographic characteristics of Eagle Syndrome, in addition to addressing diagnostic methods and therapeutic strategies. Materials and methods: A search was carried out for scientific articles published between 2016 and 2024, using the Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) and Google Scholar databases. Articles were collected in English and Portuguese, using the keywords: "eagle syndrome", "styloid syndrome", "carotid artery syndrome", "stilalgia", "eagle syndrome", "styloid syndrome", "carotid artery syndrome" and "stylalgia". Conclusion: Professionals should be aware of Eagle syndrome in cases of unilateral pain when performing activities such as swallowing, yawning and crying, without an apparent cause, especially in adult women who do not find relief with analgesics. Due to the frequency of asymptomatic cases, early radiological examinations play a crucial role in diagnostic evaluation. It is essential that Otorhinolaryngology, Neurology and Dentistry professionals are aware of this syndrome, as it is associated with a significant deterioration in quality of life. (AU)

ABSTRACT

Abstract The objective of this study was to conduct a systematic review and meta-analysis of relevant randomized control trials (RCTs) to determine the role of ibuprofen, as well as the optimum dose and duration of therapy, in preventing the incidence of heterotopic ossification (HO) after primary total hip arthroplasty (THA). A literature search was performed using the PubMed/MEDLINE and Cochrane Library databases for RCTs that compared the use of ibuprofen versus placebo as prophylaxis for HO in patients after THA. The main outcomes for this study were overall occurrence of HO, occurrence according to the Brooker classification, and gastrointestinal complications. A total of 27 potential articles were identified from the database. Eventually, four trials with 1,153 patients were included in the final analysis. When compared with placebo, the use of ibuprofen is associated with a reduction in the incidence of HO at the 3- and 12-month follow-up appointments, as well as the incidence of Brooker II and III HO (p < 0.05). However, there was no significant difference between the ibuprofen and placebo groups in terms of treatment discontinuation due to gastrointestinal complications or the incidence of Brooker I and IV HO (p > 0.05). The existing data indicates that ibuprofen is safe and efficacious in reducing the total incidence of HO along with Brooker II and III HO at follow-up. However, due to the small number of studies, the conclusions are limited; therefore, more high-quality clinical trials are required to develop guidelines for optimal dose and duration of therapy.


Resumo O objetivo deste estudo foi realizar uma revisão sistemática e metanálise de estudos clínicos randomizados (ECRs) relevantes para determinar o papel do ibuprofeno, sua dose ideal, e a duração do tratamento na prevenção de ossificação heterotópica (OH) após a artroplastia total primária do quadril (ATQ). Uma pesquisa bibliográfica foi feita nos bancos de dados PubMed/MEDLINE e Cochrane Library para a obtenção de ECRs quecomparassem ouso de ibuprofeno edeplacebo como profilaxiaparaOHem pacientes submetidos à ATQ. Os principais desfechos deste estudo foram ocorrência geral de OH, classificação de Brooker da OH, e complicações gastrintestinais. No total, 27 artigos foram identificados nos bancos de dados e 4 estudos, com 1.153 pacientes, foram incluídos na análise final. Em comparação ao placebo, o uso de ibuprofeno reduziu a incidência de OH aos 3 e 12 meses de acompanhamento e a incidência de OH Brooker II e III (p < 0,05). No entanto, não houve diferença significativa entre os grupos que receberam ibuprofeno e placebo em termos de interrupção do tratamento devido a complicações gastrintestinais ou da incidência de OH Brooker I e IV (p > 0,05). Os dados existentes indicam que o ibuprofeno é seguro e eficaz na redução da incidência total de OH e de OH Brooker II e III durante o acompanhamento. No entanto, as conclusões são limitadas devido ao pequeno número de estudos; logo, mais estudos clínicos de alta qualidade são necessários para o desenvolvimento de diretrizes em relação à dose e duração ideal da terapia.

ABSTRACT

Introducción: El objetivo principal fue evaluar la relación entre la formación de calcificaciones heterotópicas y los parámetros de alineación de la prótesis. Materiales y Métodos: La población estaba formada por 31 pacientes. Se evaluaron variables radiográficas de alineación, como ángulos alfa y beta, centro de rotación astragalino y el porcentaje de cobertura posterior de la tibia en el posoperatorio inmediato y a los 2 años. Las variables de evaluación clínica fueron: la escala analógica visual y la escala de la AOFAS, y el cuestionario SF-36 para evaluar la calidad de vida al final del seguimiento. Resultados: La etiología más frecuente de la artrosis fue la postraumática (67,7%). En el posoperatorio inmediato, el ángulo alfa promedio fue de 88,7° (rango 82-92,6; DE ± 2,61); el ángulo beta, de 84,46° (rango 78,62-91,40; DE ± 3,59). La alineación del componente tibial en el plano frontal fue neutra en 25 pacientes (80,6%), en valgo en 6 (19,4%) y en varo (0%). A los 2 años de seguimiento, el 96% tenía calcificaciones heterotópicas. Mejoraron los puntajes en la escala de la AOFAS (preoperatorio/posoperatorio: 31,90/80,94) y en la escala analógica visual (preoperatorio/posoperatorio: 8,7/1,97) (p <0,05). Conclusiones: No se halló una relación entre calcificaciones heterotópicas y peores resultados funcionales ni de dolor, excepto en los parámetros de calidad de vida (SF-36), como el rol físico, la limitación emocional y la percepción de la salud general, que empeoraron a medida que aumentó el grado de calcificaciones alrededor de la prótesis. Nivel de Evidencia: IV


Introduction: The main objective of this work is to evaluate the relationship between the formation of heterotopic calcifications and the alignment parameters of the prosthesis. Materials and Methods: The population under study comprised 31 patients. The radiographic alignment variables evaluated were alpha and beta angles, the talar center of rotation, and the percentage of posterior coverage of the tibia in the immediate postoperative period and after 2 years. The clinical evaluation variables were: VAS, AOFAS, and the SF-36 questionnaire to evaluate quality of life at the end of follow-up. Results: The most frequent etiology of osteoarthritis was post-traumatic (67.7%). In the immediate postoperative period, the mean alpha angle was 88.7° (range 82-92.6°; SD± 2.61); the mean beta angle was 84.46° (range 78°, 62-91.40°; SD ±3.59). The alignment of the tibial component in the anteroposterior plane was neutral in 25 patients (80.6%), valgus in 6 (19.4%), and varus in none. At 2 years of follow-up, 96% presented het-erotopic calcifications. An improvement was verified both in the AOFAS (pre/post 31.90/80.94) and in the VAS scales (pre/post: 8.7/1.97) (p<0.05). Conclusions: No relationship was found between heterotopic calcification and worse functional outcomes or pain, except for quality-of-life parameters (SF-36) such as physical condition, emotional limitation, and general health perception, which worsened as the degree of calcifications around the prosthesis increased. Level of Evidence: IV

ABSTRACT

@#Patients with burns are predisposed to heterotopic ossification and contracture formation. While radiographs and bone scans are used to detect heterotopic ossification, musculoskeletal ultrasound can be used to diagnose and localize the lesion in patients with contractures. A 14-year-old girl with multiple contractures of the limbs from thermal burn injury sustained three years ago underwent in-patient rehabilitation in a sub-acute burn rehabilitation unit. Despite close monitoring and daily therapy sessions, the patient had minimal improvement in the range of motion of bilateral hips. Musculoskeletal ultrasound demonstrated hyperechogenic focus on the posterolateral aspect of the bilateral hips. This report documents the advantage of diagnostic musculoskeletal ultrasound in localizing and guiding the treatment of heterotopic ossification in a burn patient with contractures.

ABSTRACT

RESUMEN: Ocasionalmente la incisura escapular puede ser reemplazada por un foramen óseo producto de la osificación del ligamento transverso superior de la escápula. Esta formación ósea se considera un factor precipitante de la compresión del nervio supraescapular. Ciento noventa y cinco escápulas de individuos adultos pertenecientes a osteotecas de universidades de Colombia (114 escápulas) y de Chile (81 escápulas), fueron estudiadas macroscópicamente para determinar la presencia de un foramen escapular óseo. Ambas escápulas de un mismo individuo colombiano (1,75 % del total) presentaban el foramen escapular y una escápula izquierda (1,23 %) presentaba esta formación en un individuo chileno. La prevalencia de la osificación del ligamento transverso superior de la escápula es muy variable en los distintos estudios y tiende a situarse inferior al 10 %, sin embargo, puede constituirse en un factor de riesgo debido al atrapamiento o compresión del nervio supraescapular, hecho conocido como neuropatía supraescapular.


SUMMARY: Occasionally the scapular notch can be replaced by a bony foramen product of the ossification of the superior transverse scapular ligament. This bone formation is considered a precipitating factor for compression of the suprascapular nerve. One hundred and ninety-five adult scapulae from Colombian (114 scapulae) and Chilean (81 scapulae) university osteotheques were studied macroscopically to determine the presence of a bony scapular foramen. Both scapulae of the same Colombian individual (1.75% of the total) presented the scapular foramen and one left scapula (1.23%) presented this formation in a Chilean individual. The prevalence of ossification of the superior transverse scapular ligament is highly variable in the different studies and tends to be less than 10%; however, it can become a risk factor due to entrapment or compression of the suprascapular nerve, a fact known as suprascapular neuropathy.

ABSTRACT

Introducción: la miositis osificante progresiva (MOP) es una enfermedad hereditaria del tejido conectivo de baja prevalencia (1:2,000,000 habitantes). Se caracteriza por osificación heterotópica con un comportamiento incierto que excepcionalmente se ha relacionado con neoplasias. Se buscó conocer la coexistencia de la MOP con neoplasias de origen mesodérmico, para que sean consideradas en el diagnóstico de otros pacientes, así como formular hipótesis para esclarecer su asociación. Caso clínico: mujer de 27 años con dolor de músculo isquitiobial y glúteo derecho que incrementaba con el ejercicio, sin remisión con analgésicos hasta limitar la movilidad de ambas extremidades. Se solicitó una serie ósea donde se evidenciaron zonas de radiolucidez heterogénea en la región de ambos muslos y pelvis de manera irregular, semejante a densidad ósea, que fue compatible con los hallazgos ecográficos y tomográficos; se concluyó que eran imágenes relacionadas con miositis osificante de cadera. La paciente refirió sintomatología gástrica y se solicitó una endoscopía que histopatológicamente reportó carcinoma gástrico difuso con células en anillo de sello; las imágenes de gabinete mostraron tumoración ovárica. Conclusión: la MOP es una patología de baja prevalencia, por lo que su conocimiento y sospecha son fundamentales para el diagnóstico. Hay poca literatura que involucre a las tres entidades; por ende, su fisiopatología y comprensión es limitada. En cuanto a la MOP, aún no hay un tratamiento curativo; sin embargo, el diagnóstico certero permite iniciar rehabilitación de manera oportuna con mejoría de la calidad de vida.


Background: Myositis ossificans progressiva (MOP) is a low prevalence hereditary connective tissue disease (1:2,000,000 habitants). It is characterized by heterotopic ossification with an uncertain behavior that has been exceptionally related to neoplasms. The objective was to know the coexistence of MOP with neoplasms of mesodermal origin, so that they can be considered in the diagnosis of other patients, as well as formulate hypotheses to clarify their association. Clinical case: 27-year-old female with right gluteal and ischitiobial muscle pain that increased with exercise, without remission with analgesics until limiting the mobility of both extremities. A bone series was requested where areas of heterogeneous radiolucency were evidenced in the region of, both, thighs and pelvis in an irregular manner, similar to bone density, which was compatible with the ultrasound and tomographic findings; we concluded that they were images of myositis ossificans of the hip. The patient reported gastric symptoms and an endoscopy was requested, which histopathologically reported diffuse gastric carcinoma with signet ring cells; cabinet images showed an ovarian tumor. Conclusion: MOP is a low prevalence disease, which is why its knowledge and suspicion are essential for the diagnosis. We found little literature that involves the three entities; therefore, their pathophysiology and understanding is limited. Regarding MOP, at this moment there is no curative treatment; however, an accurate diagnosis allows to start rehabilitation in a timely manner with an improvement in the quality of life.

ABSTRACT

INTRODUCCION En los últimos años, la artroplastia de disco cervical (ADC) se ha utilizado ampliamente en pacientes como alternativa a la disectomía y fusión cervical anterior (DFCA). Sin embargo, se han informado osificación heterotópica (OH) y fusion espontánea después de ADCs, y el desarrollo de OH puede dificultar el mantenimiento de movimiento después de la artroplastia. MATERIALES Y METODOS El procedimiento ADC con prótesis Activ C y M6-C se realizó en 127 pacientes. El tiempo medio de seguimiento fue de 58.4 meses, con un rango de 51 a 66 meses. RESULTADOS Las osificaciones de grado 1 estuvieron presentes en 11 niveles (8,6%). Un total de 45 (35,4%) segmentos eran de OH de grado 2. Las OHs que produjeron restricciones del rango de movimiento estuvieron presentes en 13 (10,2%) casos. A los 5 años de seguimiento, sólo había 9 (7,0%) pacientes con osificación de grado 4 en el grupo de prótesis de disco artificial M6-C. En el análisis de la supervivencia tras la ocurrencia de OH, la mediana de los pacientes fue de 28,3 5,6 meses. El grupo de prótesis de disco artificial Activ C tuvo una supervivencia estadísticamente más larga (49,5 7,8 meses) que el grupo de disco M6-C. CONCLUSIONES En este estudio, el 61,4% de los pacientes desarrollaron OH en un período de seguimiento medio de 58,4 meses. En el análisis de la supervivencia tras la ocurrencia de OH, la mediana de los pacientes fue de 28.3 5.6 meses. El grupo de prótesis de disco artificial Activ C tuvo una supervivencia estadísticamente más larga (49.5 7.8 meses) que el grupo de disco M6-C.


INTRODUCTION In recent years, cervical disk arthroplasty (CDA) has become widely used in patients as a substitute to anterior cervical diskectomy and fusion (ACDF). However, heterotopic ossification (HO) and spontaneous fusion after CDA have been reported, and maintenance of motion following arthroplasty can be hindered by the development of HO. MATERIALS AND METHODS The CDA procedure with Activ C and M6-C prostheses was performed on 127 patients. The mean follow-up time was of 58.4 months, ranging from 51 to 66 months. RESULTS Grade-1 ossifications were present in 11 (8.6%) levels. A total of 45 (35.4%) segments showed grade-2 HO. Cases of HO that led to restrictions in the range of motion were present in 13 (10.2%) patients. Fives year postoperatively, there were only 9 (7.0%) patients with grade-4 ossifications in the M6-C artificial disk prosthesis group. In the survival analysis after HO occurrence, the median survival of the patients was of 28.3 5.6 months. The Activ C artificial disk prosthesis group had a statistically longer survival (49.5 7.8 months) than the M6-C disk group. CONCLUSION In the present study, 61.4% of the patients developed HO at a mean follow-up period of 58.4 months. In the survival analysis after HO occurrence, the median survival of the patients was of 28.3 5.6 months. The Activ C artificial disk prosthesis group had a statistically longer survival (49.5 7.8 months) than the M6-C disk group.

ABSTRACT

Metaplastic breast carcinoma is a rare subtype of invasive breast carcinoma. Metaplastic carcinoma with osseous differentiation is exceptionally uncommon. Because of the heterogenous microscopy of the lesion, various clinical and radiological features are observed, leading to diagnostic difficulty. Herein, we present a case of a 43-year-old female with a recurrent breast lump, who was clinically diagnosed as a phyllodes tumor. However, histopathological examination revealed metaplastic carcinoma with extensive osseous differentiation.

ABSTRACT

Abstract Objective To evaluate the clinical and radiographic results as well as complications related to patients undergoing arthroscopic treatment of subspine hip impingement. Methods We retrospectively evaluated 25 patients (28 hips) who underwent arthroscopic treatment of subspine impingement between January 2012 and June 2018. The mean follow-up was 29.5 months, and the patients were evaluated clinically by using the Harris hip score modified by Byrd (MHHS), the non-arthritic hip score (NAHS), and in terms of internal rotation and hip flexion. In addition, the following items were evaluated by imaging exams: the center-edge (CE) acetabular angle, the Alpha angle, the presence of a sign of the posterior wall, the degree of arthrosis, the presence of heterotopic hip ossification, and the Hetsroni classification for subspine impingement. Results There was an average postoperative increase of 26.9 points for the MHHS, 25.4 for the NAHS (p < 0.0001), 10.5° in internal rotation (p < 0.0024), and 7.9° for hip flexion (p < 0.0001). As for the radiographic evaluation, an average reduction of 3.3° in the CE angle and of 31.6° for the Alpha angle (p < 0.0001). Eighteen cases (64.3%) were classified as grade 0 osteoarthritis of Tönnis, and 10 (35.7%) were classified as Tönnis grade 1. Two cases (7.1%) presented grade 1 ossification of Brooker. Most hips (n = 15, 53.6%) were classified as type II of Hetsroni et al. Conclusion In the present study, patients undergoing arthroscopic treatment with subspine impingement showed improvement in clinical aspects and radiographic patterns measured postoperatively, with an average follow-up of 29.5 months.


Resumo Objetivo Avaliar os resultados clínicos e radiográficos assim como as complicações relacionadas a pacientes submetidos ao tratamento artroscópico do impacto subespinhal do quadril. Métodos Foram avaliados retrospectivamente 25 pacientes (28 quadris) submetidos ao tratamento artroscópico de impacto subespinhal entre janeiro de 2012 e junho de 2018. O seguimento médio foi de 29,5 meses, e os pacientes foram avaliados clinicamente pelo Harris hip score modificado por Byrd (MHHS), o non-arthritic hip score (NAHS), e quanto à rotação interna e flexão do quadril. Além disso, foram avaliados por exames de imagem: o ângulo center-edge (CE) acetabular, o ângulo alfa, a presença de sinal da parede posterior, o grau de artrose, a presença de ossificação heterotópica do quadril e a classificação de Hetsroni para Impacto Subespinhal. Resultados Observou-se aumento médio pós-operatório de 26,9 pontos para o MHHS, 25,4 para o NAHS (p < 0,0001), 10,5° na rotação interna (p < 0,0024) e 7,9° para flexão do quadril (p < 0,0001). Quanto à avaliação radiográfica, observou-se redução média de 3,3° no ângulo CE e de 31,6° para o ângulo alfa (p < 0,0001). Foram classificados 18 casos (64,3%) como artrose grau 0 de Tönnis e 10 (35,7%) como Tönnis 1. Dois casos (7,1%) apresentaram ossificação grau 1 de Brooker. A maioria dos quadris (n = 15; 53,6%) foi classificada como tipo II de Hetsroni et al. Conclusão No presente estudo, os pacientes submetidos a tratamento artroscópico de impacto subespinhal apresentaram melhora nos aspectos clínicos e nos padrões radiográficos aferidos pós-operatoriamente, com seguimento médio de 29,5 meses.

ABSTRACT

Abstract Secondary osteoma cutis is a phenomenon that may occur in several conditions. When it occurs in a melanocytic nevus it is named osteonevus of Nanta, an event considered uncommon and characterized by the presence of bone formation adjacent or interposed with melanocytic cells. There are reports of its occurrence in various melanocytic lesions, being more frequently associated with intradermal nevus. We report a case of osteonevus of Nanta in combined nevus, possibly the first description of this association.

ABSTRACT

Abstract Objective In the present study, we present the results with at least 10 years of follow-up of the cervical disc prosthesis implanted in a single level. Methods Retrospective study of patients undergoing single-level total cervical disc replacement (TCDR). Clinical results included the neck disability index (NDI) and the visual analogue scale (VAS) in the preoperative period, one year postoperatively, and a minimum of 10 years of follow-up. The radiographic parameters included cervical mobility, segmental lordosis, C2-C7 angle, heterotopic ossification (HO), facet and joint degeneration (FJD) and adjacent segment disease (ASD). Results We identified 22 patients, 16 women and 6 men with mean age of 39.7 years old (26-51 years old), of which fifteen completed a minimum follow-up of 10 years. There was a statistically significant improvement of NDI and VAS (p < 0.001) between the preoperative and the postoperative periods (1 year or > 10 years). At the end of 10 years, HO was observed in 59% of the cases. The mobility of the implant was preserved in 80% of the patients. Radiological evidence of ASD was recorded in 6 patients (40%). There was no correlation between the clinical parameters evaluated and the presence of ASD or the different classes of HO. Conclusion Clinical improvement in all evaluated parameters, which persists over time. Most implants maintained mobility, as has already been demonstrated in other studies with shorter follow-ups. In a significant percentage of cases, ASD was observed, questioning the concept of motion preserving technology. However, we did not have any surgical intervention for this reason, since there was no correlation with worse clinical results.


Resumo Objetivo No presente estudo, apresentamos os resultados com um acompanhamento mínimo de 10 anos da artroplastia total do disco cervical (ATDC) em um nível. Métodos Estudo retrospectivo de pacientes submetidos a ATDC em um nível. Os resultados clínicos incluíram o índice de incapacidade relacionada ao pescoço (IIRP) e a escala visual analógica (EVA) no período pré-operatório, um ano pós-operatório e um mínimo de 10 anos de acompanhamento. Os parâmetros radiográficos incluíram a mobilidade cervical, lordose segmentar, ângulo C2-C7, ossificação heterotópica (OH), degeneração facetária e articular (DFA) e doença do segmento adjacente (DSA). Resultados Identificados 22 pacientes, 16 mulheres e 6 homens com média de idade de 39,7 anos (26-51 anos), dos quais 15 tiveram um acompanhamento mínimo de 10 anos. Foi verificada melhoria estatisticamente significativa do IIRP e EVA (p < 0,001) entre pré-operatório e pós-operatório. (1 ano ou > 10 anos). Ao final de 10 anos, OH foi observada em 59% dos casos. A mobilidade do implante foi preservada em 80% dos pacientes. Houve evidência radiológica de DSA em 6 pacientes (40%). Não houve correlação entre os parâmetros clínicos avaliados e a presença de DSA ou as diferentes classes de OH. Conclusão Melhoria clínica em todos os parâmetros avaliados, que persiste ao longo do tempo. A maioria dos implantes manteve a mobilidade, como já demonstrado em estudos anteriores com acompanhamentos mais curtos. Numa percentagem significativa, a DSA estava presente, questionando o conceito da tecnologia de preservação de movimento. No entanto, sem nenhuma intervenção cirúrgica por esse motivo, uma vez que não houve correlação com piores resultados clínicos.

Caso clínico: Niño de 11 años consulta por múltiples lesiones osificadas en tronco y región cervical con importante limitación en su movilidad. En el examen físico destaca un ortejo mayor corto. Estudio genético muestra mutación del gen ACVR1. Recibe tratamiento con periodos cortos de corticosteroides posterior a traumas y previo a procedimientos, asociado a un manejo multidisciplinario. Revisión de la literatura: A la fecha el principal tratamiento es la prevención de los brotes de osificación y el uso de corticosteroides o antiinflamatorios cuando los brotes ya se iniciaron. Están en curso ensayos clínicos con bifosfonatos y anticuerpos anti-activina A. Conclusión: En la actualidad no existe un tratamiento específico, sin embargo, un diagnóstico precoz, la prevención de brotes y nuevas terapias podrían mejorar el pronóstico de los pacientes.


ntroduction: Fibrodysplasia ossificans progressiva is a rare autosomal dominant congenital disease characterized by skeletal malformations and progressive disabling heterotopic ossification. Clinical case: An 11-year-old boy consulted with multiple ossified lesions in the trunk and cervical regions associated with significant limitation in mobility. On physical examination, the big toe is short. Genetic study shows ACVR1 gene mutation. He received treatment with short corticosteroid periods after traumas and prior to clinical procedures, as well as a multidisciplinary management.Literature review: To date the main treatment is the prevention of ossification flare-ups and the use of corticosteroids or anti-inflammatories when they have already started. Clinical trials are ongoing with bisphosphonates and anti-activin A antibodies.Conclusion: There is currently no specific treatment, however, early diagnosis, prevention of flare-ups and new therapies could improve the prognosis of patients.

ABSTRACT

RESUMEN Un síndrome caracterizado por dolor cervical y un apófisis estiloides alargado fue descrito por primera vez por Watt Eagle en 1937. Aunque el síndrome de Eagle en su variante vascular es raro y no es reconocido como causa clara de disección carotídea, en los últimos años ha sido reportado un incremento del número de casos de disección carotídea causada por una apófisis estiloides alargada. Paciente de 56 años que acudió al servicio de urgencias por paresia facial izquierda aguda y habla confusa. Presentaba dolor cervical de dos días de evolución, relacionado con un ataque de tos. Se activó el código ictus y la tomografía computarizada (TC) mostró isquemia del lóbulo temporal derecho y disección bilateral de la arteria carótida interna. La angio-TC de los troncos supraaórticos con reconstrucción tridimensional, identificó una apófisis estiloides alargado en ambos lados. El paciente fue sometido a una angioplastía con colocación de dos stents. Debido al alto riesgo de padecer nuevo ictus, se decidió realizar tratamiento quirúrgico. Para el lado derecho se realizó un abordaje transoral y en el izquierdo un abordaje abierto. La apófisis estiloides alargado es una causa importante de disección carotídea y de las complicaciones cerebrovasculares relacionadas.


ABSTRACT A syndrome characterized by cervical pain and an abnormally elongated styloid process was first described by Watt Eagle in 1937. Even though vascular Eagle syndrome is uncommon and is not well recognized as a cause for carotid artery dissection, in the last few years there have been an increasing number of case reports of carotid artery dissection caused by an elongated styloid process. A 56 years old man presented to the emergency department with acute left facial weakness and slurred speech. He complained of two days neck pain, related to a coughing fit. The code stroke protocol was activated and imaging showed a right temporal bone stroke and a bilateral internal carotid artery dissection. A scan angiography of the supra-aortic vessels with 3D reconstruction was performed showing a bilateral abnormally elongated styloid process. The patient underwent angioplasty with two stent placements. Due to the high risk of recurrent strokes, the patient was evaluated in the otolaryngology department for styloid process resection. Finally a transoral approach for the right side and an open approach for the left side were performed. We have to consider an elongated styloid process as an important cause of carotid artery dissection and subsequent cerebrovascular complications

ABSTRACT

OBJETIVO: Reportar el caso de un paciente con antecedente de múltiples cirugías por peritonitis y abdomen abierto, con hallazgo intraoperatorio de osificación heterotópica en el mesenterio. CASO CLÍNICO: Paciente masculino de 59 años, con antecedente de apendicectomía complicada hace 12 meses, que en esa oportunidad requirió manejo de abdomen abierto, colectomía derecha e ileostomía terminal. Un año posapendicectomía reingresa para reconstitución de tránsito con hallazgo intraoperatorio de masa calcificada en mesenterio, de 15 x 10 x 6 cm, cuyo estudio histológico informa osificación heterotópica mesentérica. Esta entidad es de baja frecuencia, asociada al antecedente de trauma y cirugía abdominal, y se ha descrito como causa de morbimortalidad. El manejo quirúrgico resectivo es factible por equipos con experiencia. CONCLUSIÓN: Se describe un caso con antecedente de abdomen abierto, con posterior hallazgo de osificación heterotópica mesentérica. Este caso clínico es representativo por sus factores de riesgos clásicos y manejo empleado para su resolución.


OBJECTIVE: Report the case of a patient with a history of multiple surgeries due to peritonitis and open abdomen, with intraoperative finding of mesenetrioc heterotopic ossification. CLINICAL CASE: A 59-year-old male patient with a history of complicated appendectomy 12 months ago, which requires the management of an open abdomen, right colectomy and terminal ileostomy. One year after appendectomy, is readmitted for transit reconstitution. Intraoperative finding were calcified mass in mesentery, of 15 x 10 x 6 cm, whose histological study reports mesenteric heterotopic ossification. This entity has low frequency, and is associated with a history of trauma and abdominal surgery, is described as a cause of morbidity and mortality. Resective surgical management is feasible for experienced teams. CONCLUSION: A case with antecedent of open abdomen is described, with later finding of mesenteric heterotopic ossification. This clinical case is representative for its classic risk factors and management used for its resolution.

ABSTRACT

Heterotopic ossification has been described in papillary thyroid carcinoma in association with high incidence of extrathyroidal invasion, multifocality, lymph node metastasis, and older age. Nevertheless, it has not been described as a specific subtype of papillary thyroid carcinoma, because of its rarity. We described the case of an 80-year-old female patient, with familial history of papillary thyroid carcinoma. In the annual screening examination, she was diagnosed with thyroid nodules. The patient was submitted to a thyroidectomy because the fine needle aspiration cytology was positive for malignancy according to the Bethesda classification. The surgical specimen analyses showed a multifocal papillary carcinoma with one major lesion in the left lobe measuring 0.9 cm, and two small lesions (0.4 cm and 0.2 cm) in the right lobe. Only the biggest lesion in the right lobe had the osteoid matrix with rare osteoclasts and fat metaplasia with progenitor cells. There was perineural invasion, but vascular invasion was not identified. The margins were free and there was no extrathyroidal extension. In the left lobe there was an oncocytic nodule and a lipomatous follicular nodule. In recent years there has been a significant increase in the diagnosis of thyroid cancer, mainly because of the finding of microcarcinomas as a result of many requests for cervical image exams. Future studies may define (i) whether papillary thyroid carcinoma with heterotopic ossification is a true histological variant; (ii) the causes of that alteration; and (iii) eventual follow-up implications.

ABSTRACT

Fibrodysplasia ossificans progressiva (FOP) or myositis ossificans, is a genetic disease, with a prevalence of 1 in 2.000.000. It is caused by pathogenic variants in ACVR1 gene and characterized by soft tissue heterotopic ossification, starting in the second decade of life. It is associated to early mortality caused by respiratory complications. It evolves in flare-ups, triggered by soft tissue injuries; therapy is symptomatic, using analgesia, steroids and diphosphonates. We report a 12-year-old female with left renal agenesis, hallux valgus and intellectual disability, presenting with a six months history of thoracic kyphosis, tender nodules in the thorax, and rigidity of right elbow and left knee. Clinical examination revealed dysmorphic facial features. A magnetic resonance showed heterotopic ossification nodules, which was confirmed with spinal radiography. These findings prompted the diagnosis of FOP. Pain treatment was started, and prednisone was used during flare-ups. The ACVR1 gene was analyzed and a pathogenic variant, p. Arg206His, was found, confirming the diagnosis of FOP.

ABSTRACT

La osificación heterotópica (OH), es la formación anormal de hueso maduro dentro de tejidos blandos extra esqueléticos donde normalmente no existe tejido óseo. Varias formas de OH han sido descritas de acuerdo a su presentación clínica, localización y ocurrencia progresiva o aislada. Su presentación en pacientes sometidos a inmovilización prolongada en el contexto de coma farmacológicamente inducido, en ausencia de lesiones del sistema nervioso central, es poco habitual. Presentamos el caso de una paciente de 40 años, sexo femenino, sin antecedentes mórbidos, que presenta episodio de pancreatitis aguda grave, manejada en UCI. Producto de lo anterior, requiere coma farmacológicamente inducido por 3 meses y hospitalizaciones reiteradas y prolongadas durante los 10 meses siguientes. Durante 3 años desde la resolución de su cuadro inicial evoluciona con alteración progresiva de la marcha y rigidez de la extremidad inferior derecha, sin eventos traumáticos durante ese período. Se objetiva mediante radiografía y TAC foco de OH coxofemoral derecha. Se resuelve de forma quirúrgica y biopsia de pieza operatoria confirma el diagnóstico. La paciente logra buena recuperación posterior. NIVEL DE EVIDENCIA: IV


Heterotopic ossification (HO) is the abnormal formation of mature bone within extraskeletal soft tissues where bone does not exist. Various presentation of HO have been described according to the clinical settings and location of the lesions, and progressive or isolated occurrence. A rare form of presentation occurs in induced coma patients with long-term immobilization and without central nervous system injuries. We present the case of a 40 years old female patient, without previous morbidity, who develop a severe acute pancreatitis. The patient requires an intensive care unit management (ICU) and a 3-month pharmacology induced coma and reiterative and prolonged hospitalizations during the next 8 months. During 3 years after resolution of her base disease, patient develops a progressive step claudication and a hip rigidity in adduction and external rotation. A coxofemoral HO focus is confirmed by radiology and CT. A surgical treatment of HO was performed, and the initial diagnose confirmed by anatomic pathology after biopsy of the injury. Patient had a favorable outcome.

ABSTRACT

The incidence of heterotopic ossification in adolescents appears to be lower than in adults. There exist very few reports of heterotopic ossification with total bony ankylosis in child or adolescent populations. We describe a case of total bony ankylosis of the elbow secondary to heterotopic ossification, in a 14-year-old female. Total ankylosis of the elbow at 45 degrees of flexion was noted 6 months post-surgery, and complete surgical excision of the heterotopic mass was performed. After an additional one-time dose of radiation therapy and nonsteroidal anti-inflammatory drug medication, full range of motion was obtained without any recurrence or other complications, up to the last follow-up of 30 months.

ABSTRACT

Ossification of the posterior longitudinal ligament (OPLL) can be defined as an ectopic ossification in the tissues of spinal ligament showing a hyperostotic condition. OPLL is developed mostly in the cervical spine and clinical presentations of OPLL are majorly myelopathy and/or radiculopathy, with serious neurological pathology resulting in paralysis of extremities and disturbances of motility lowering the quality of life. OPLL is known to be an idiopathic and multifactorial disease, which genetic factors and non-genetic factors including diet, obesity, physical strain on the posterior longitudinal ligament, age, and diabetes mellitus, are involved into the pathogenesis. Up to now, surgical management by decompressing the spinal cord is regarded as standard treatment for OPLL, although there might be the risk of development of reprogression of ossification. The molecular pathogenesis and efficient therapeutic strategy, especially pharmacotherapy and/or preventive intervention, of OPLL has not been clearly elucidated and suggested. Therefore, in this review, we tried to give an overview to the present research results on OPLL, in order to shed light on the potential pharmacotherapy based on molecular pathophysiologic aspect of OPLL, especially on the genetic/genomic factors involved into the etiology of OPLL.
