RESUMO

The aim of the present study was to analyze palatal marginal alveolar exostosis (PMAE) and palatal torus (PT). Cone-beam computed tomography (CBCT) of the maxilla in multiplanar sections and volumetric renderings were used to assess this. PT and PMAE were classified according to location and morphology. Height, width, length, and thickness of the overlying mucosa were determined. The prevalence of PT and PMAE was assessed according to sex and age group. The correlation between the occurrence of PMAE and PT was also evaluated. A total of 385 CBCT scans were examined. PT was found in 38.70% of the sample and located more frequently in the middle third of the maxilla (52.35%) with a flat shape (42.95%). PMAE was found in 54.80% of the sample, bilaterally in 56.40% of the cases, and located more frequently in the molar region (62.42%) in the form of small nodules (36.97%). The mucosa covering PMAE was generally thicker than that over PT. The use of CBCT for the identification of PT and PMAE in vivo showed high frequencies of both conditions. The occurrence of PMAE was independent of the presence of PT.

RESUMO

Se presenta el caso de un lactante de 2 meses que fue llevado a consulta varias veces por llanto problemático, inicialmente interpretado como de causa gastrointestinal. Dado que el síntoma persistía, se sospechó de una fractura debido a su asociación con la movilización de los miembros y la palpación de una tumoración en la cara anterior de la tibia derecha. Las radiografías mostraron compromiso poliostótico diafisario y lesiones compatibles con compromiso cortical de huesos largos. Se realizó el diagnóstico operativo de síndrome de Caffey-De Toni-Silverman y se inició el tratamiento con antiinflamatorios no esteroideos, lo que resultó en una remisión sintomática. Posteriormente, se confirmó el diagnóstico mediante la identificación de la variante patogénica COL1A1 en estado heterocigota. Se trata de una patología rara de la cual se estima una incidencia de 48/100 000 y hay menos de 150 casos descritos al momento.

Here we describe the case of a 2-month-old infant who consulted several times due to excessive crying, initially interpreted as having a gastrointestinal cause. Since the symptom persisted, a fracture was suspected due to its association with mobilization of the limbs and palpation of a mass on the anterior aspect of the right tibia. X-rays showed diaphyseal polyostotic involvement and lesions compatible with cortical involvement of long bones. Caffey-De Toni-Silverman syndrome was diagnosed and treatment with nonsteroidal anti-inflammatory drugs was initiated, resulting in symptom remission. Subsequently, the diagnosis was confirmed by the identification of the pathogenic heterozygous variant COL1A1. This is a rare condition with an estimated incidence of 48/100 000 individuals, and less than 150 cases have been described to date.

RESUMO

RESUMEN La hiperostosis cortical infantil (HIC) o enfermedad de Caffey es un trastorno óseo autolimitado que se caracteriza por fiebre, irritabilidad, inflamación de los tejidos blandos y engrosamiento cortical de uno o más huesos. Es más común en el primer semestre de vida. Se informa el caso de un lactante de 3 meses con las características clínico-radiográficas propias de la enfermedad y los hallazgos de laboratorio más comunes que permitieron un acertado diagnóstico y seguir una conducta adecuada. El cuadro agudo se mantuvo durante pocos días y se observó resolución total del edema en cuatro semanas. El reconocimiento de esta rara infección evitará adoptar métodos diagnósticos y terapéuticos invasivos para el paciente.

ABSTRACT Infantile cortical hyperostosis (ICH) or Caffey disease is a self-limiting bone disorder characterized by fever, irritability, soft tissue swelling and cortical bone thickening. It is more common in infants < 6 months of age. We report the case of a 3-month-old infant with the clinical and radiographic characteristics of the disease and the most common laboratory findings which enabled an accurate diagnosis and appropriate management. The acute episode persisted for several days, followed by a complete resolution of the edema within four weeks. Identifying this rare infection will help avoid invasive diagnostic and therapeutic strategies.

RESUMO

Objetivo: La enfermedad de Caffey o hiperostosis cor- tical infantil es una enfermedad rara que afecta uno o más huesos en los primeros meses de vida y debido a su baja inci- dencia está subdiagnosticada, y por tanto se aplican procedi- mientos invasivos innecesarios en su estudio y tratamiento. Se presenta un caso clínico atípico de enfermedad de Caffey en una paciente mayor de 1 año de edad y su resolución. Caso clínico: El servicio de Cirugía Maxilofacial del Hospital Provincial Pediátrico Eduardo Agramonte Piña de Camagüey, Cuba, atiende a una niña de 1 año y 10 meses que se encontraba hospitalizada por presentar una inflamación alarmante en la región facial y cervical precedida de un cua- dro febril y dificultad para alimentarse. Se indicaron los estu- dios apropiados, cuyos resultados, junto a las características clínicas, permitieron diagnosticar la enfermedad de Caffey. Aunque sea una enfermedad rara, es importante estudiarla para realizar un correcto análisis de cada caso y diferenciarla de otras enfermedades que requieren de conductas terapéuti- cas agresivas (AU)

Aim: Caffey's disease or infantile cortical hyperostosis is a rare disease that affects one or more bones in the first months of life and due to its low incidence, it is underdiag- nosed, and therefore unnecessary invasive procedures are applied in its study and treatment. An atypical clinical case of Caffey's disease in a patient older than 1 year and its reso- lution is presented. Case report: The Maxillofacial Surgery service of the Eduardo Agramonte Piña Provincial Pediatric Hospital in Camagüey, Cuba, takes the case of a 1 year and 10-month-old female patient who was hospitalized for an alarming inflam- mation in the facial and cervical region, preceded by a fever and difficulty to eat. The appropriate studies were indicated, which results, together with the clinical characteristics, al- lowed the diagnosis of Caffey's disease. Although it is a rare entity, it is important to study it to carry out a correct analysis of each case and differentiate it from other diseases that re- quire aggressive therapeutic behaviors (AU)

RESUMO

Introducción: La enfermedad de Caffey es una patología ósea inflamatoria, rara, autolimitada, casi exclusiva de lactantes. Objetivos: Jerarquizar el abordaje diagnóstico de una patología poco frecuente. Caso clínico: 4 meses 22 días, varón, consulta por irritabilidad y edema de miembro inferior izquierdo de 4 días de evolución. Sin traumatismos ni fiebre. Examen físico: edema indurado en tercio medio e inferior de pierna izquierda, no rubor ni calor local. Dolor a la palpación de cara anterior y lateral de tibia y peroné. Limitación funcional, no resaltos óseos. Radiografía: engrosamiento del periostio en tibia y peroné a nivel diafisario. Hemograma: Glóbulos blancos 15.380 KU/L, Hemoglobina 10,8 g/dL, Plaquetas 816.400 10/ul, proteína C reactiva 13,90 mg/dl. Con planteo de probable infección osteoarticular se inicia clindamicina ( gentamicina e ingresa a cuidados moderados. Dada la persistencia de edema e irritabilidad, al quinto día se solicita resonancia magnética: hallazgos sugerentes de un probable proceso inflamatorio- infeccioso de partes blandas con compromiso óseo. Completa 14 días de clindamicina y 7 días de gentamicina intravenosa, hemocultivo negativo. Persiste con edema, irritabilidad y dolor. A los 21 días, se revalora la presentación clínica-imagenológica, se plantea enfermedad de Caffey. Se inicia anti-inflamatorio con buena evolución. Conclusiones: La enfermedad de Caffey es una colagenopatía rara, que afecta lactantes. El diagnóstico es clínico - radiológico (irritabilidad, tumefacción de partes blandas y alteraciones radiológicas). El pronóstico a largo plazo suele ser favorable. Es importante considerar el diagnóstico en lactantes que se presentan con esta sintomatología para evitar retrasos diagnósticos e instauración de tratamientos innecesarios.

Introduction: Caffey's disease is a rare disease that is reported almost exclusively in infants. Objective: Describe the case of a rare pathology, prioritizing the diagnostic approach. Clinical case: 4 month -old, healthy male. Consultation due to irritability and edema of the left lower limb for 4 days. No trauma or fever. Physical examination: indurated edema in the left leg, no redness or local heat. Pain on palpation of the anterior and lateral aspect of the tibia and fibula. Functional limitation, no bony protusions. Leg x-ray: thickening of the periosteum in the tibia and fibula at the diaphyseal level. Hemogram: White Blood Cells 15,380 KU/L Hemoglobin: 10.8 g/dL. Platelets: 816,400 10/ul, C-reactive protein: 13.90 mg/dl. He was admitted with a suggestion of probable osteoarticular infection. Clindamycin ( gentamicin is started. Given the persistence of edema and irritability despite treatment, on the fifth day an MRI was requested: findings suggestive of a probable inflammatory-infectious process of soft tissues with bone involvement. Completed 14 days of clindamycin and 7 days of intravenous gentamicin, blood culture negative. It persists with edema, irritability and pain. After 21 days, the clinical-imaging presentation was reassessed and Caffey's disease was considered. Anti-inflammatory begins with good evolution. Conclusions: Caffey's disease is a rare collagenopathy, that affects infants. The diagnosis is clinical - radiological (irritability, soft tissue swelling and radiological alterations). The long-term prognosis is usually favorable. It is important to consider the diagnosis in infants who present with these symptoms to avoid diagnostic delays and initiation of unnecessary treatments.

RESUMO

A neonate at 13 days of age underwent a lid and conjunctiva-sparing orbital exenteration for a massive right orbital teratoma. To reduce the degree of orbital contraction, the entire temporalis muscle was rotated into the orbit along with a dermis-fat graft. Sequential postoperative orbital imaging showed that hyperostosis developed in the orbital apex at the age of two months. Despite a significant expansion of the fat graft, by the age of 4 years, hyperostosis had progressed to the anterior portion of the orbit associated with over-pneumatization of the paranasal sinuses. This case demonstrates that the bony changes in the orbit after neonatal exenteration are complex and involve the development of the paranasal sinuses.

RESUMO

Tuberous sclerosis complex (TSC) is a genetic disorder, frequently characterized by early dermatological manifestations. The recognition and adequate description of these dermatological manifestations are of utmost importance for early diagnosis, allowing for the implementation of therapeutic and preventive measures. Fibrous cephalic plaques (FCPs) are considered a major diagnostic criterion for TSC, as FCPs are the most specific skin lesions of TSC. The localization, consistency, color, and size of FCPs vary widely, which can cause diagnostic delay, especially in patients with atypical presentations. The present report describes a female TSC patient with a confirmed heterozygous pathogenic genotype, NG_005895.1 (TSC2_v001): c.2640-1G>T, who presented with uncommon large and bilateral FCPs causing bilateral ptosis and marked with hyperostosis of the diploe that generated an asymmetry of the brain parenchyma. Differential diagnoses considered initially in this patient due to the atypical FCPs are described.

RESUMO

Hyperostosis manifests itself and develops differently in taxonomically related species. Radiographic images of individuals belonging to different size classes of Atlantic Moonfish Selene setapinnis and Lookdown Selene vomer were obtained from two different estuarine areas of Rio de Janeiro/Brazil. In S. setapinnis, hyperostosis occurred in 65.22% of the specimens analyzed in three different skeletal regions. All specimens of S. vomer had hyperostosis in four regions. Patterns of occurrence were detected in both species, and the affected regions did not coincide in the same bone region, except for the cleithrum. Hyperostosis in S. setapinnis were observed in high frequencies of seventh dorsal pterygiophore, whereas in specimens of S. vomer this condition was detected to a greater extent in the neural spines of the second abdominal vertebra and first to third caudal vertebrae. The data demonstrated a relationship between the sexual maturity and the occurrence and development of hyperostotic bones in ageing process of individuals. It is the first description of S. vomer with a hyperostosis phenomenon for the species on the Brazilian coast.

RESUMO

La enfermedad de Erdheim-Chester (EEC) es una patología poco frecuente, caracterizada por presentar infiltración xantogranulomatosa sistémica, con afección de diversos sistemas incluido el óseo. La EEC se encuentra descripta dentro de las enfermedades osteocon-densantes (EO), las cuales se reconocen por presentar aumento de la masa ósea y compromiso tanto de huesos largos como planos. La presentación clínica de la EEC es variada: puede presentar desde un curso indolente hasta manifestaciones multisistémicas. Las características radiológicas son de gran importancia para establecer su diagnóstico. Presentamos una paciente con EEC, con esclerosis bilateral de huesos largos, que exhibe algunas características diferenciales con relación a otros casos reportados: a) afectación exclusivamente ósea a 10 años de evolución, b) compromiso bilateral y simétrico de distinta magnitud, c) esclerosis cortical endóstica y perióstica, d) signos radiológicos sugestivos de periostitis, d) ausencia de compromiso metafisario, e) ausencia de actividad metabólica de las lesiones en las imágenes de 18F-FDG PET/CT.Conclusión: la presencia de lesiones osteocondensantes bilaterales exclusivamente en huesos largos deben hacer sospechar EEC. La ausencia de compromiso metafisario y de actividad metabólica en 18F-FDG PET/CT ha sido raramente descripta. (AU)

Erdheim - Chester disease (ECD) is a rare disease, characterized by systemic xanthogranulomatous infiltration, with involvement of various organs including bone. ECD is described within the sclerosing bone disorders, which are recognized for presenting increased bone mass and involvement of both long and flat bones. The clinical presentation of ECD is diverse, ranging from an asymptomatic course to multisystemic manifestations. Radiological features are of great importance to establish the diagnosis. We describe here a patient with ECD, with bilateral sclerosis of long bones that presents some differential characteristics in relation to other reported cases: a) exclusively bone involvement at 10 years of evolution, b) bilateral and symmetric involvement of different magnitude, c) endosteal and periosteal cortical sclerosis d) radiological signs suggestive of periostitis, d) absence of metaphyseal involvement, e) absence of metabolic activity of the lesions in 18F-FDG PET/CT.Conclusion: the presence of bilateral osteosclerosis exclusively in long bones should lead to suspect ECD. The absence of metaphyseal involvement and metabolic activity in 18F-FDG PET/CT have been rarely described. (AU)

RESUMO

La hiperostosis vertebral anquilosante es una rara enfermedad degenerativa, considerada como una forma clínica de presentación de la osteoartritis de columna vertebral. Afecta fundamentalmente a pacientes masculinos por encima de 50 años de edad. El dolor, la limitación de la movilidad y las manifestaciones neuropáticas constituyen sus principales manifestaciones clínicas. El diagnóstico se centra en la identificación de hallazgos radiológicos. El objetivo de este estudio es mostrar los elementos radiológicos que permiten llegar al diagnóstico de esta enfermedad. Se realiza una breve descripción de los elementos básicos y característicos de la hiperostosis vertebral anquilosante y se expone una radiografía anteroposterior de la columna dorso lumbar donde se pueden apreciar los elementos distintivos, desde el punto de vista imagenológico, de esta enfermedad. El diagnóstico precoz de la enfermedad y el tratamiento adecuado minimiza el riesgo de disminución de la movilidad, lo cual constituye la principal complicación de la hiperostosis vertebral anquilosante.

ABSTRACS Ankylosing vertebral hyperostosis is a rare degenerative disease, considered a clinical presentation of spinal osteoarthritis. It mainly affects male patients over 50 years of age. Pain, limitation of mobility and neuropathic manifestations constitute its main clinical manifestations. Diagnosis focuses on the identification of radiological findings. The objective of this study is to show the radiological elements that allow us to reach the diagnosis of this disease. A brief description of the basic and characteristic elements of ankylosing vertebral hyperostosis is made and an anteroposterior x-ray of the thoracolumbar spine is exposed where the distinctive elements, from the imaging point of view, of this disease can be appreciated. Early diagnosis of the disease and appropriate treatment minimizes the risk of decreased mobility, which is the main complication of ankylosing vertebral hyperostosis.

RESUMO

STUDY DESIGN: Case series study. PURPOSE: To describe demographic metrics, and clinical and radiographical outcomes of surgical treatment in patients with ankylosed spine (ASP) such as diffuse idiopathic skeletal hyperostosis (DISH) or ankylosing spondylitis (AS) and non-ankylosed spines (NAS) suffering from hyperextension-distraction spine fractures. METHODS: Patients diagnosed with hyperextension-distraction fractures between 2012 and 2020 were identified. A retrospective analysis of clinical and surgical data was performed. Similarities between patients with ASP and NAS were evaluated by Fisher's exact test. RESULTS: Of the 22 patients, 13 had ASP (10 patients with DISH, 3 AS) and nine NAS. Most of these injuries involved the thoracolumbar spine (45.4%). All patients with NAS presented some sign of spondylosis: facet joint degeneration, intervertebral osteochondrosis, and anterolateral osteophytes. None of the patients with NAS and 30.7% with ASP suffered low-energy mechanisms (p = .11). All the patients with NAS and 61% of the patients with ASP had associated injuries (p = .04). On average, the instrumented levels were four (range, 2-6), achieving a fusion rate of 94.7% in all groups. Most of the ASP and NAS presented post-operative complications respectively (p = .65). CONCLUSION: Hyperextension-distraction spine fractures are not unique in ASP. In patients with spondylosis and high-energy accidents, we should suspect those fractures and rule out associated injuries, fractures in other vertebral segments, and acute spinal cord injury. The four-level instrumentation achieved an effective fusion rate in all patients.

RESUMO

RESUMEN El síndrome de Morgagni-Stewart-Morel es una rara enfermedad que se caracteriza por hiperostosis frontal interna bilateral asociada a alteraciones metabólicas, psiquiátricas, hipertensión arterial y disfunción de pares craneales de etiología no definida. Se presenta el caso de una paciente de 77 años con historia de diabetes mellitus tipo 2, hipertensión arterial sistémica y trastorno psiquiátrico, que ingresó en el Servicio de Neurología del Hospital General Universitario Dr. Gustavo Aldereguía Lima de Cienfuegos con cuadro de disartria y hemiparesia derecha. Se realizaron estudios de diagnóstico por imagen de cráneo donde se observó la presencia de hiperostosis frontal interna extensa, atrofia cortical y un infarto talámico izquierdo. Durante su estancia hospitalaria se documentó la presencia de obesidad grado I, hirsutismo e hipercolesterolemia. La paciente cumplió con los criterios del síndrome de Morgagni-Stewart-Morel al manifestar la presencia de hiperostosis frontal interna con manifestaciones, endocrinológicas y neuropsiquiátricas. Se presenta el caso con el objetivo de evidenciar el diagnóstico de una enfermedad de baja incidencia en pacientes cerebrovasculares isquémicos con la presencia de una sintomatología que incluye varios factores de riesgo vasculares bien documentados.

ABSTRACT Morgagni-Stewart-Morel syndrome is a rare disease characterized by bilateral internal frontal hyperostosis associated with metabolic and psychiatric disorders, arterial hypertension, and dysfunction of the cranial nerves of undefined etiology. The case of a 77-year-old patient with a history of type 2 diabetes mellitus, systemic arterial hypertension and psychiatric disorder, who was admitted to the Neurology Service of the Dr. Gustavo Aldereguía Lima University Hospital in Cienfuegos with dysarthria and right hemiparesis is presented. Diagnostic skull imaging studies were performed where the presence of extensive internal frontal hyperostosis, cortical atrophy and a left thalamic infarction was observed. During his hospital stay, the presence of grade I obesity, hirsutism and hypercholesterolemia was documented. The patient met the criteria for Morgagni-Stewart-Morel syndrome by manifesting the presence of internal frontal hyperostosis with endocrinological and neuropsychiatric manifestations. The case is presented in order to demonstrate the diagnosis of a low incidence disease in ischemic cerebrovascular patients with the presence of symptoms that include several well-documented vascular risk factors.

RESUMO

El síndrome de Forestier es una enfermedad reumatológica, de origen desconocido, que consiste en la calcificación de diferentes zonas del cuerpo, predominantemente a nivel del ligamento vertebral común anterior, donde se forman osteofitos capaces de producir sintomatología variada y de intensidad variable. Normalmente asintomática, aunque, cuando afecta la columna cervical, el síntoma más común es la disfagia. Se presenta un caso de Síndrome de Forestier que consultó por disfagia en la Unidad de Cirugía de Cabeza y Cuello del Servicio de Otorrinolaringología del Instituto de Previsión Social de Asunción, Paraguay. La semiología permitió observar un abombamiento submucoso en la pared posterior de la orofaringe de 1,5 cm de diámetro, que pudo ser evaluado y confirmado por tomografía. Debido a poca intensidad de la sintomatología y escasa repercusión en el estado general se decidió realizar un tratamiento conservador con buenos resultados, tras dos años de seguimiento clínico. En estos casos la cirugía ocupa un lugar secundario, ya sea ante el fracaso de esta conducta conservadora o ante la progresión de los síntomas

Forestier Syndrome is a rheumatological disease of unknown origin, which consist in calcification of different areas of the body, predominantly at the level of the anterior common vertebral ligament, where osteophytes capable of producing varied symptoms of variable intensity are formed. Normally asymptomatic, although, when it affects the cervical spine, the most common symptom is dysphagia.A case of Forestier syndrome is presented who consulted for dysphagia in the Head and Neck Surgery Unit of the Otolaryngology Service of the Institute of Social Prevision, Asuncion, Paraguay. The semiology allowed to observe a submucosal bulge in the posterior wall of the oropharynx of 1,5 cm in diameter, which could be evaluated and confirmed by tomography.Due to the low intensity of the symptoms and little impact on the general state, it was decided to carry out a conservative treatment with good results, after two years of clinical follow-up. In these cases, surgery occupies a secondary place, either before the failure of this conservative behavior or the progression of the symptoms.

RESUMO

RESUMEN: La cribra orbitalia o hiperostosis porótica del techo orbitario es considerada una manifestación ósea microperforativa de condiciones patológicas hematológicas, especialmente la anemia ferropénica. Este hallazgo, se enmarca de manera casi exclusiva a estudios en poblaciones arqueológicas. El propósito de este estudio fue describir la expresión de cribra orbitalia en una población arqueológica de Chile central. Restos óseos de 32 individuos fueron analizados, los cuales fueron obtenidos de la población del Monumento Arqueológico Cementerio Tutuquén, los que están depositados en el Museo Regional de Rancagua. En cada una de la muestras incluidas, se evaluaron períodos de datación, sexo, rango etáreo, presencia v/s ausencia de cribra orbitalia y en los casos en que ésta estuvo presente, se determinó su intensidad mediante visión directa con lente de aumento. Un 59,38 % de los individuos presentó cribra orbitalia. De éstos, 26,32 % fueron de sexo femenino, 31,58 % de sexo masculino y 42,10 % indeterminado. De los individuos del período 10.000 AP, 33,33 % presentó cribra orbitalia; de los individuos del período 7.000 AP un 50 % y de los individuos pertenecientes al período 1.000 AP, un 68,4 %. Al clasificar la severidad de la cribra orbitalia se observó que 31,57 % de los individuos presentaron Cribra orbitalia tipo I; 36,84 % tipo II; 10,52 % tipo III; 10,52 % tipo IV y 10,52 % tipo V. Los datos aportados complementarán el conocimiento morfopatológico de la órbita ocular humana desde el estudio de poblaciones arqueológicas.

SUMMARY: The cribra orbitalia or porotic hyperostosis of the orbital roof is considered a microperforative bone manifestation of hematological pathological conditions, especially iron deficiency anemia. This finding is almost exclusively part of studies in archaeological populations. The purpose of this study was to describe the expression of cribra orbitalia in an archaeological population of central Chile. Bone remains of 32 individuals were analyzed, which were obtained from the population of the Tutuquén Cemetery Archaeological Monument, which are deposited in the Regional Museum of Rancagua. In each of the included samples, dating periods, sex, age range, presence v / s absence of cribra orbitalia were evaluated and in the cases in which it was present, its intensity was determined by direct vision with a magnifying lens. The 59.38 % of the individuals presented cribra orbitalia. Of these, 26.32 % were female, 31.58 % male, and 42.10 % undetermined. Of the individuals in the period 10,000 BP, 33.33 % presented cribra orbitalia; of the individuals of the period 7,000 AP, 50% and of the individuals belonging to the period 1,000 AP, 68.4 %. When classifying the severity of the cribra orbitalia, it was observed that 31.57 % of the individuals had type I; 36.84 % type II; 10.52 % type III; 10.52 % type IV and 10.52 % type V. The data provided will complement the morpho-pathological knowledge of the human eye orbit from the study of archaeological populations.

RESUMO

Resumen El síndrome de Camurati-Engelmann, también conocido como displasia diafisaria progresiva, es una enfermedad rara, autosómica dominante y con una prevalencia de uno por cada millón de habitantes. Genera mutaciones del factor de crecimiento transformante beta, que participa en la proliferación ósea. Son frecuentes las manifestaciones osteomusculares y neurológicas, con escasas expresiones de laboratorio. El diagnóstico se basa en la clínica, los hallazgos radiológicos y la confirmación genética; el tratamiento se dirige al control sintomático y el pronóstico es incierto. La presente publicación tiene como objetivo compartir con la comunidad médica el tercer caso de síndrome de Camurati-Engelmann conocido en Colombia. Se trata de una paciente femenina de 33 años con cuadro clínico de distonías intensas y signos y síntomas característicos de este síndrome, cuyo diagnóstico fue confirmado por prueba molecular, encontrando la presencia de la variante patogénica p.Arg156Cys en el gen TGF-β1, con presentación de novo. MÉD.UIS.2021;34(1): 119-27.

Abstract Camurati-Engelmann syndrome, also known as progressive diaphyseal dysplasia, is a rare, autosomal dominant disease with a prevalence of one per million inhabitants. It generates mutations of the transforming growth factor beta, which participates in bone proliferation. Osteomuscular and neurological manifestations are frequent, with few laboratory expressions. The diagnosis is based on the clinic, radiological findings, and genetic confirmation, treatment is aimed at symptom control and prognosis is uncertain. The objective of this publication is to share with the medical community the third case of Camurati-Engelmann syndrome known in Colombia. This is a 33-year- old female patient with a clinical picture of intense dystonia and characteristic signs and symptoms of this syndrome, whose diagnosis was confirmed by molecular testing, finding the presence of the pathogenic variant p.Arg156Cys in the TGF-β1 gene, with de novo presentation.

RESUMO

SUMMARY: An increased thickening of the frontal bone by irregular laminar additions on the inner surface just deep to the dura mater have been known in the archaeological and medical record as hyperostosis frontalis interna (HFI). The distribution of this is idiosyncratically restricted to the frontal and has no known etiology. The prevalence among post-menopausal females and rarity in males suggests that it is hormonally driven. Here we report histopathological findings of particularly hormonally active organs (pituitaries, gonads and liver) from a geriatric cadaveric sample in which HFI is assessed. HFI was present in 50 % of males (7/14) and 95 % (21/22) of females. All males with HFI had testicular atrophy or had testes absent. Males with HFI category C or D had moderate to severe testicular atrophy. Decreased numbers of interstitial cells (Leydig cells) were present in 83.3 % of males with HFI. All but one female (21/22) from this study exhibited evidence of HFI, and ovarian pathologies were unevenly distributed (fibromas in two) and most exhibited signs of being healthy and post-menopausal. Liver pathologies had opposite patterns between the sexes, with more liver pathologies occurring among males without HFI (particularly passive congestion and bile stasis). The only exceptions were that the one case of liver neoplasia was found in a male with HFI and steotosis was found in two cases with HFI and one case without HFI. In females all cases of liver pathologies (steotosis, hepatitis, passive congestion, fibrosis, and bile stasis) were associated with HFI. It appears that gonadal pathology is most closely associated with HFI in males but not females, suggesting that the role of estradiol in this unusual growth of bone in geriatric humans may be worth investigating further.

RESUMEN: Un aumento del engrosamiento del hueso frontal, por adiciones laminares irregulares en la superficie interna, justo en la profundidad de la duramadre, se conoce en los registros arqueológicos y médicos como hiperostosis frontal interna (HFI). La distribución de ésta, se restringe idiosincráticamente al hueso frontal y no tiene etiología conocida. La prevalencia entre las mujeres posmenopáusicas y la rareza en los hombres sugiere que se debe a las hormonas. Aquí informamos los hallazgos histopatológicos de órganos hormonalmente activos (hipófisis, gónadas e hí- gado) de una muestra de cadáveres geriátricos en la que se evaluó HFI. La HFI estuvo presente en el 50 % de los hombres (7/14) y el 95 % (21/22) de las mujeres. Todos los hombres con HFI tenían atrofia testicular o no tenían testículos. En los hombres con HFI categoría C o D se observó atrofia testicular de moderada a grave. Hubo una disminución en el número de células intersticiales (células de Leydig) en el 83,3 % de los hombres con HFI. En 21de 22 mujeres se observó evidencia de HFI, y las patologías ováricas se distribuyeron de manera desigual (fibromas en dos) y la mayoría exhibió signos de estar sana y posmenopáusica. Las patologías hepáticas tenían patrones opuestos entre los sexos, con más patologías hepáticas entre los hombres sin HFI (particularmente congestión pasiva y estasis biliar). Las excepciones fueron que el único caso de neoplasia hepática se encontró en un varón con HFI y se presentó esteatosis en dos casos con HFI y un caso sin HFI. En las mujeres, todos los casos de patologías hepáticas (esteatosis, hepatitis, congestión pasiva, fibrosis y estasis biliar) se asociaron con HFI. Al parecer la patología gonadal está más estrechamente asociada con la HFI en los hombres que en las mujeres, lo que sugiere un rol del estradiol en este crecimiento inusual de hueso en hombres de avanzada edad. Sería importante realizar investigaciones más detalladas precisas respecto a la hiperostosis frontal interna.

RESUMO

Resumen La hiperostosis esquelética difusa idiopática (DISH) es una enfermedad sistémica caracterizada por la osificación del ligamento longitudinal anterior de la columna. Los pacientes suelen ser asintomáticos o presentar dolor leve o rigidez, sin embargo, cuando afecta la región cervical puede ocasionar disfagia, disfonía o disnea. Presentamos el caso de un paciente de 63 años con disfonía y disfagia en quien los estudios demostraron desplazamiento del aritenoides y colapso del seno piriforme debido a un osteofito a nivel de C4. El paciente presentó mejoría con tratamiento conservador. Realizamos una discusión del caso y una revisión de la literatura sobre diagnóstico y tratamiento de esta patología.

Abstract Diffuse idiopathic skeletal hyperostosis (DISH) is a systemic disease characterized by ossi- fication of the anterior longitudinal ligament of the spine. Patients are usually asympto- matic, or present mild pain or stiffness, however cervical compromise can cause dysphagia, dyspnea and dysphonia. We present the case of a 63-year-old patient with hoarseness and dysphagia. Studies revealed anterior displacement of the arytenoid cartilage and collapse of the pyriform sinus secondary to an osteophyte at C4 level. The patient showed improvement with conservative management. We present a discussion about this case and the available scientific evidence on the diagnosis and treatment of this pathology.

RESUMO

OBJECTIVES: Cribra orbitalia (CO) and porotic hyperostosis (PH) are porous cranial lesions (PCLs) classically associated with iron-deficiency anemia in bioarchaeological contexts. However, recent studies indicate a need to reassess the interpretation of PCLs. This study addresses the potential health correlates of PCLs in a contemporary sample by examining relationships between the known cause of death (COD) and PCL presence/absence. METHODS: This study includes a sample of 461 juvenile individuals (6 months to 15 years of age) who underwent examination at the University of New Mexico's Office of the Medical Investigator between 2011 and 2019. The information available for each individual includes their sex, age at death, and their COD and manner of death. RESULTS: Odds ratio of having CO (OR = 3.92, p < .01) or PH (OR = 2.86, p = .02) lesions are increased in individuals with respiratory infections. Individuals with heart conditions have increased odds of having CO (OR = 3.52, p = .03) lesions, but not PH. CONCLUSION: Individuals with respiratory infection are more likely to have CO and/or PH. CO appears to have a greater range of health correlates than PH does, as indicated by the heart condition results. However, individuals with congenital heart defects are at higher risk for respiratory infections, so bony alterations in cases of heart conditions may be due to respiratory illness. Since respiratory infection remains a leading cause of mortality today, CO and PH in bioarchaeological contexts should be considered as potential indicators of respiratory infections in the past.

RESUMO

RESUMEN Introducción: La hiperostosis esquelética idiopática difusa (DISH, por sus siglas en inglés) es una afección caracterizada por la calcificación y la osificación progresiva de los ligamentos y las entesis. La mayoría de los pacientes permanecen asintomáticos hasta etapas avanzadas de la enfermedad, donde la limitación y el dolor son característicos. Objetivo: Describir las características demográficas, clínicas y radiológicas de los pacientes con DISH evaluados en el Centro Médico Imbanaco de Cali y en la Clínica de Artritis Temprana, en Cali, Colombia. Materiales y métodos: Es un estudio descriptivo, de corte transversal. Se revisaron los registros de pacientes diagnosticados con DISH, seguidos entre enero de 2000 y octubre de 2018. El diagnóstico se confirmó según los criterios de Resnick-Niwayama. Se encontraron 24 pacientes, todos se incluyeron para el análisis final. Resultados y discusión: En esta serie se encontraron 20 varones y 4 mujeres. La mediana de edad al diagnóstico fue de 70,5 arios (RIQ: 61,3-73,8 arios), siendo menor en las mujeres (71,5 versus 60 años; p = 0,04). La mediana de tiempo de evolución de los síntomas fue de 5 años (RIQ: 3-10 años), la duración fue menor en el grupo de las mujeres (5 versus 4 años; p = 0,20). El 54,2% tenían sobrepeso y el 20,8% eran diabéticos. El síntoma principal fue la limitación cervical. Los segmentos vertebrales (C: cervical; T: torácico; L: lumbar) más afectados por la osificación del ligamento longitudinal anterior (LLA) fueron C5-C6, T8-T10 y L1-L3. La afección periférica predominó en las crestas ilíacas. Todos los pacientes realizaron terapia física y 3 fueron sometidos a cirugía cervical. El grado de limitación funcional fue valorado en 19 pacientes a través de los cuestionarios modified Health Assessment Questionnaire (mHAQ) y Bath Ankylosing Spondylitis Functional Index (BASFI). La mediana del puntaje de ambos cuestionarios fue 2 veces más alta en las mujeres. Conclusión: La DISH fue más frecuente en varones mayores de 65 años y se asoció con enfermedades metabólicas como la obesidad y la diabetes. Aunque las diferencias no fueron significativas, los resultados sugieren que las mujeres presentan un fenotipo grave de la enfermedad explicado por el inicio temprano y curso progresivo de los síntomas, así como mayor limitación funcional medida por mHAQ y BASFI.

ABSTRACT Introduction: Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterised by calcification and progressive ossification of ligaments and entheses. Most patients remain asymptomatic until advanced stages of the disease, where limitation and pain are characteristic. Objective: To describe the demographic, clinical, and radiological characteristics of patients with DISH evaluated in the Centro Médico Imbanaco and Clínica de Artritis Temprana, in Cali, Colombia. Materials and methods: A descriptive, cross-sectional study was conducted by reviewing the records of patients diagnosed with DISH between January 2000 and October 2018. The diagnosis was confirmed according to the Resnick-Niwayama criteria. A total of 24 patients were found, and all were included for the final analysis. Results and discussion: The series included 20 men and 4 women, with a median age at diagnosis of 70.5 years (IQR 61.3-73.8 years), beinglower in women (71.5 versus 60 years; P=.04). The median time of onset of the symptoms was 5 years (IQR 3-10 years), and the duration was shorter in women (5 versus 4 years; P=.20). It was observed that 54% were overweight and 20% were diabetic. The main symptom was cervical limitation. The most affected vertebral segments due to the ossification of the anterior longitudinal ligament (ALL) were C5-C6, T8-T10 and L1-L3 (cervical C; thoracic T; lumbar L). The peripheral involvement was mainly in the iliac crests. All patients received physiotherapy, and three of them underwent cervical surgery. The degree of functional limitation was assessed in 19 patients using the mHAQ (Modified Health Assessment Questionnaire) and BASFI (Functional Ankylosing Spondylitis Functional (BASFI) questionnaires. The median score of both questionnaires was 2 times higher in women Conclusion: Diffuse idiopathic skeletal hyperostosis was more frequent in men over 65 years of age, and was associated with metabolic conditions such as obesity and diabetes. Although the differences were not significant, the results suggest that women have a more severe phenotype of the disease, explained by the early onset and progressive course of symptoms, as well as greater functional limitation measured by mHAQ and BASFI.
