Actualización sobre el síndrome de Eagle y sus complicaciones neurocardiológicas: casos clínicos / An update on Eagle´s syndrome and its neuro-cardiological complications: clinical cases

El síndrome de Eagle o síndrome estilohioideo o sín-drome de la arteria carótida es un trastorno que se origina por la mineralización y elongación del pro-ceso estiloides. Factores traumáticos agudos y cró-nicos, así como otras teorías, han sido propuestos para explicar la etiología y patogenia de esta altera-ción. El conjunto de síntomas puede incluir: dolor fa-ríngeo, odinofagia, disfagia, cefalea, con irradiación a oreja y zona cervical. Si bien existen varias clasifi-caciones, de manera universal se acepta que existen principalmente dos formas de presentación de esta patología: el tipo I o clásico, generalmente asociado a un trauma faríngeo y acompañado de dolor en la zona faríngea y cervical, y el tipo II o carotídeo, que sue-le presentar molestia cervical, cefalea y alteración de la presión arterial, con riesgo de daño de la ac-tividad cardíaca. La identificación de este síndrome suele ser confusa dada la similitud de los síntomas con otras afecciones. El diagnóstico debe realizarse en base a los síntomas y a los estudios por imágenes específicos. El tratamiento puede ser conservador y actuar simplemente sobre los síntomas, o bien, qui-rúrgico. El objetivo del presente trabajo es realizar una revisión actualizada de la literatura sobre el sín-drome de Eagle y presentar tres casos clínicos con distintas manifestaciones (AU)

Eagle's syndrome or styloid syndrome or stylo-carotid artery syndrome is a disease caused by mineralization and elongation of the styloid process. Acute and chronic traumatic factors, along with other hypothesis, have been proposed to explain the aetiology and pathogenesis of this condition. Symptoms can include: pharynx pain, odynophagia, dysphagia, headache, with radiating pain to the ear and neck. Despite there are several classifications, it is universally accepted that this pathology can present in two forms: the type I or classic, generally associated to tonsillar trauma and characterized by pharyngeal and neck pain, and the type II or carotid artery type, which frequently presents with neck pain, headache, blood pressure variation, with risk of damage to cardiac function. Identifying of Eagle's syndrome is often confusing because some symptoms are shared with other pathologies. Diagnosis must be made on the basis of symptoms and imaging studies. Treatment can be conservative, acting only on symptoms, or surgical. The aim of this paper is to provide an updated review of the literature on Eagle syndrome and to present three clinical cases with different manifestations (AU)

Reference values for carotid artery intima-media thickness among community adult dwellers in Shenzhen City / 中华预防医学杂志

Objective: To establish reference values for carotid intima-media thickness (CIMT) of adult dwellers in Shenzhen City. Methods: The study was conducted based on the Shenzhen heart failure epidemiological survey from 2021 to 2022. In this survey, residents aged 18 years and above in Shenzhen were selected by using a multi-stage stratified random sampling method. General information, cardiovascular disease (CVD) related behavior and carotid ultrasound examination and etc. were collected from the participants. People with CVD factors, a history of atherosclerotic cardiovascular disease, carotid plaque or having no carotid ultrasound examination results were excluded. The parameter regression model based on fractional polynomial was used to establish the reference values of CIMT by age and sex. Results: A total of 2 163 healthy individuals were enrolled in the final analysis, including 576 males (26.6%) and 1 587 females (73.4%). The fractional polynomial regression of the CIMT mean and standard deviation was obtained. For men, the regression was meanCIMT=0.324 7+0.006 9×age and SDCIMT=0.076 9+0.001 2×age. For women, the regression was meanCIMT=0.354 9+0.005 4×age and SDCIMT=0.041 6+0.002 0×age. Conclusion: The age and sex reference values for CIMT of adult people in Shenzhen established in this study could provide the latest reference standards for early screening of subclinical CVD.

Introducción: El hipotiroidismo subclínico se relaciona con alteraciones cardiovasculares como la aterosclerosis carotidea subclínica por daños endoteliales como consecuencia de varios factores siendo el grosor intima-media carotideo (GIMC) un marcador reconocido, cuya elevación se menciona con frecuencia asociada a esta disfunción tiroidea. Objetivo: Determinar los efectos del tratamiento sustitutivo de pacientes con hipotiroidismo subclínico en el GIMC. Métodos: Se realizó un estudio de intervención que incluyó 94 pacientes con diagnóstico de hipotiroidismo subclínico sin tratamiento sustitutivo, que acudieron a la consulta de Endocrinología del hospital 10 de octubre a los cuales se les realizó determinación de TSH, colesterol total, colesterol LDL, colesterol HDL, triglicéridos y se les realizó US carotideo al inicio del estudio y al año de logrado el estado eutiroideo con tratamiento sustitutivo, para establecer diferencias en los parámetros evaluados antes y después del tratamiento sustitutivo. Resultados: Previo al tratamiento se encontró hipercolesterolemia en el 87,2 por ciento de los pacientes e hipertrigliceridemia en y 38,3 por ciento, mientras que, que valores elevados de colesterol LDL y disminuidos de colesterol HDL fueron hallados en el 55,3 por ciento y 19,3 por ciento de los mismos, el GIMC se mostró dentro del rango de normalidad. Tras el tratamiento con levotiroxina todos los valores medios de los parámetros estudiados se modificaron excepto en el caso de los triglicéridos Conclusiones: El tratamiento sustitutivo del hipotiroidismo subclínico tiene efectos beneficiosos sobre el GIMC, lo que pudiera ser secundario, entre otros factores, a la mejoría del perfil lipídico(AU)

Introduction: Subclinical hypothyroidism is related to cardiovascular alterations such as subclinical carotid atherosclerosis due to endothelial damage as a consequence of various factors, carotid intima-media thickness (CIMT) being a recognized marker, whose elevation is frequently mentioned in association with this thyroid dysfunction. Objective: To determine the effects of replacement therapy in patients with subclinical hypothyroidism in CIMT. Methods: An intervention study was carried out in 94 patients diagnosed with subclinical hypothyroidism, who did not have substitutive treatment. They were treated in Endocrinology consultation at 10 de Octubre hospital. These subjects underwent determination of TSH, total cholesterol, LDL cholesterol, cholesterol HDL, triglycerides. They got carotid ultrasound at the beginning of the study and one year after achieving euthyroid status with replacement treatment, to establish differences in the parameters evaluated before and after replacement treatment. Results: Prior to treatment, hypercholesterolemia was found in 87.2 percent of patients and hypertriglyceridemia in 38.3 percent, while elevated LDL cholesterol and decreased HDL cholesterol values were found in 55.3 percent and 19. .3 percent of them, CIMT was within the normal range. After treatment with levothyroxine, all the mean values of the parameters studied were modified, except in the case of triglycerides. Conclusions: Subclinical hypothyroidism replacement therapy has beneficial effects on CIMT, which could be secondary, among other factors, to the improvement of the lipid profile(AU)

Carotid doppler ultrasonography in patients with co-existing type 2 diabetes mellitus and hypertension in Nigeria

Background:The co-existence of diabetes mellitus (DM) and hypertension (HTN) has been rising globally with subclinical atherosclerotic complications. These vascular changes can be detected using carotid ultrasonography. Objectives: To determine and compare the carotid arterial structural wall changes and blood flow velocities of adults with co-existing DM and HTN with age-and sex-matched non-diabetic, non-hypertensive controls. Methods: A cross-sectional comparative study of 300 participants comprising 200 adults with co-existing DM and HTN and 100 age-and sex-matched controls was done. Their carotid arteries were examined bilaterally for plaques, carotid intima media thickness (CIMT) and flow velocities ­peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI) and resistive index (RI) using 4­12MHz linear array transducer. Visceral obesity and serum lipids were also assessed. Results: The mean age of the subjects was 56.13 ± 6.93 years; they comprised 38% males and 62% females. The subjects' CIMT was statistically significantly higher (p = 0.001) with a three-fold mean increase (45.5%) compared to the controls (13.7%). Lower flow velocities but higher indices were also observed in the subjects. Strong and significant correlations were observed between EDV and PI r =-0.663, p=>0.001), EDV and RI (r = -0.661, p=>0.001) and PI and RI (r =0.988, p= >0.001)among the subjects. Conclusion: Significant reduction in flow velocities with increased CIMT may be an early indication of subclinical atherosclerosis. Therefore, carotid ultrasonography should be mandatory in individuals at risk for early detection and possible prevention of atherosclerotic complications.

Effects of moderate dose rosuvastatin on carotid plaque in patients with diabetes mellitus evaluated by magnetic resonance imaging / 中华心血管病杂志

Objective: To observe the effect of lipid regulating therapy on carotid atherosclerotic plaque in diabetic patients. Methods: The REACH study, conducted between March 2009 and February 2012, enrolled asymptomatic patients with magnetic resonance imaging (MRI) confirmed carotid atherosclerotic plaque, who had never taken lipid-lowering drugs. Patients were treated with a moderate dose of rosuvastatin for 24 months. Blood lipid levels were measured and carotid MRI was performed at baseline, 3 and 24 months after treatment. The volume of carotid wall and lipid-rich necrotic core (LRNC) were measured by image analysis software. This study retrospectively analyzed patients in the REACH study. Patients were divided into diabetes group and non-diabetic group. The changes of blood lipid level and MRI parameters of carotid atherosclerotic plaque were compared between the two groups and their correlation was analyzed. Results: A total of 38 patients with carotid atherosclerotic plaque were included in this study, including 13 patients (34.2%) in the diabetic group and 25 patients (65.8%) in the non-diabetic group. Baseline parameters were comparable between the two groups, except higher HbA1c level in diabetes group (P<0.05). Compared with baseline, the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) levels were significantly decreased at 3 and 24 months in both two groups (P<0.05). The change of high-density lipoprotein cholesterol (HDL-C) in diabetes group was not obvious, while it was significantly increased in non-diabetic group at 24 months ((1.38±0.33) mmol/l vs. (1.26±0.26) mmol/l, P<0.05). MRI results showed that the volume and percentage of LRNC remained unchanged at 3 months, slightly decreased at 24 months (64.86 (45.37, 134.56) mm3 vs. 75.76 (48.20, 115.64) mm3, P>0.05) and (15.84% (11.47%, 24.85%) vs. 16.95% (11.64%, 22.91%), P>0.05) in diabetic group. In non-diabetic group, the volume and percentage of LRNC were significantly decreased at 3 months (63.01 (44.25, 188.64) mm3 vs. 72.49 (51.91, 199.59) mm3, P<0.05) and (13.76% (8.81%, 27.64%) vs. 16.04% (11.18%, 27.05%), P<0.05) respectively. Both parameters further decreased to (55.63 (27.18, 179.40) mm3) and (12.71% (8.39%, 24.41%)) at 24 months (both P<0.05). Wall volume, lumen volume and percent wall volume (PWV) were not affected post therapy in both two groups(P>0.05). There were no correlations between the changes of plaque parameters including volume and percentage of LRNC, wall volume, lumen volume, PWV and the changes of blood lipid parameters (TC, LDL-C, HDL-C and TG) in 3 and 24 months (P>0.05). Conclusion: Lipid-lowering therapy possesses different effects on carotid atherosclerotic plaque in diabetic and non-diabetic patients, and the LRNC improvement is more significant in non-diabetic patients as compared to diabetic patients.

Increased serum chemerin levels associated with carotid intima-media thickness / Aumento dos níveis séricos de chemerin associados à espessura das camadas intima-media carotídea

ABSTRACT Background: Elevated levels of chemerin can predict future ischemic cerebrovascular disease. Although chemerin is thought to play a role in atherosclerotic inflammation, whether circulating chemerin levels are associated with the severity of atherosclerosis remains to be determined. Objectives: Through the use of carotid Doppler ultrasonography, our aim in this study was to investigate the relationships of serum chemerin levels with carotid intima-media thickness (CIMT) as an indicator of generalized atherosclerosis. Methods: This study compared 40 patients with ischemic stroke and 40 healthy subjects. Measurements were made at end-diastole using color Doppler ultrasonography (CDUS) after a 5-min rest interval in a quiet and dark room. CIMT was defined as the distance between the innermost edge of the luminal echo to the innermost edge of the media/adventitia echo. CIMT was measured in the posterior wall of both common carotid arteries within 1 cm proximally to the bulbus. Three measurements were made on both sides and the average measurement was taken as the CIMT. Serum chemerin levels were determined in all patients and healthy subjects. Results: Serum chemerin levels were significantly higher in the patient group than in the control group (p=0.004). Serum chemerin levels were positively correlated with CIMT (p<0.05). There was a significant difference between the groups with regard to CIMT (p<0.001). Conclusion: Elevated serum chemerin levels appear to be associated with CIMT, thus suggesting that a link exists between chemerin and atherosclerotic ischemic cerebrovascular disease.

RESUMO Introdução: Níveis elevados de chemerin podem prever doenças cerebrovasculares isquêmicas futuras. Embora se acredite que a chemerin desempenhe um papel na inflamação aterosclerótica, ainda não foi determinado se os níveis circulantes de chemerin estão associados à gravidade da aterosclerose Objetivos: Por meio do uso da ultrassonografia Doppler da carótida, nosso objetivo neste estudo foi investigar as relações dos níveis séricos de chemerin com a espessura da íntima-média da carótida (EIMC) como um indicador de aterosclerose generalizada. Métodos: Este estudo comparou 40 pacientes com AVC isquêmico e 40 indivíduos saudáveis. As medidas foram feitas no final da diástole usando ultrassonografia Doppler em cores (USDC), após um intervalo de descanso de 5 minutos em um quarto silencioso e escuro. A EIMC foi definida como a distância entre a borda mais interna do eco luminal e a borda mais interna do eco da mídia/adventícia. EIMC foi medido na parede posterior de ambas as artérias carótidas comuns dentro de 1 cm proximalmente ao bulbo. Três medições foram feitas em ambos os lados e a medição média foi tomada como o EIMC. Os níveis séricos de chemerin foram determinados em todos os pacientes e indivíduos saudáveis. Resultados: Os níveis séricos de chemerin foram significativamente maiores no grupo de pacientes do que no grupo controle (p=0,004). Os níveis séricos de chemerin foram positivamente correlacionados com EIMC (p<0,05). Houve diferença significativa entre os grupos em relação à EIMC (p<0,001). Conclusão: Níveis séricos elevados de chemerin parecem estar associados com a EIMC, sugerindo que existe uma ligação entre chemerin e doença cerebrovascular isquêmica aterosclerótica.

Fresh vegetable and fruit consumption and carotid atherosclerosis in high-cardiovascular-risk population: a cross-sectional study in Jiangsu, China / Consumo de frutas e verduras frescas e aterosclerose carotídea em uma população de alto risco cardiovascular: um estudo transversal em Jiangsu, China / Consumo de verduras frescas y fruta y la aterosclerosis carotídea en una población con alto riesgo cardiovascular: un estudio trasversal en Jiangsu, China

This study aimed to investigate the association of vegetable and fruit consumption with carotid plaque (CP) and carotid intima-media thickness (CIMT), two predictors of carotid atherosclerosis, within urban and rural adults at high risk of developing cardiovascular diseases (CVDs) in regional China. A total of 11,392 adults at high CVD risk were identified from general population of 71,511 in this cross-sectional study, conducted between November of 2015 and May of 2016 in the Jiangsu Province. Among these 11,392 high risk participants, CP prevalence was 36.7%. The independent variables, vegetable and fruit intake frequency, were assessed by a food frequency questionnaire. The outcome variables, CIMT and CP, were measured by ultrasound examination. The ANCOVA analysis showed no association between CIMT values and vegetable and fruit intake frequencies. Multivariate logistic regression models were introduced to examine the association between vegetable and fruit intake and CP. After adjustment for potential confounders, the odds ratios (ORs) for participants who occasionally and daily consumed vegetable to experience any CP were 0.67 (95%CI: 0.58-0.78) and 0.70 (95%CI: 0.62-0.79), respectively, compared with those rarely consumed vegetable. While the adjusted ORs were 0.77 (95%CI: 0.64-0.92) and 0.80 (95%CI: 0.68-0.94), separately, for occasional and daily vegetable consumers to develop single CP relative to their counterparts who rarely consumed any vegetables. However, no significant association between fruit consumption and CP was observed. Among the Chinese population at high CVD risk, consumption of fresh vegetables was negatively associated with the risk of developing carotid plaque.

O estudo buscou investigar a associação entre consumo de frutas e verduras e placa carotídea (PC) e espessura íntima-média carotídea (EIMC), dois preditores de aterosclerose entre adultos das áreas urbana e rural com alto risco de desenvolver doenças cardiovasculares (DCVs) em uma região da China. Foram identificados 11.392 adultos com alto risco de DCV, entre 71.511 indivíduos da população geral, em um estudo transversal entre novembro de 2015 e maio de 2016 na Província de Jiangsu. Entre esses 11.392 participantes de alto risco, a prevalência de PC foi de 36,7%. As variáveis independentes, ou seja, frequências de consumo de frutas e verduras, foram avaliadas através de um questionário de frequência alimentar. As variáveis de desfecho, EIMC e PC, foram medidas por ultrassom. A análise ANCOVA não mostrou associação entre valores de EIMC e frequências de consumo de frutas e verduras. Foram introduzidos modelos de regressão logística multivariada para examinar a associação entre consumo de frutas e verduras e PC. Depois de ajustar para potenciais fatores de confusão, as ORs para participantes com consumo eventual e diário de verduras para qualquer PC foram 0,67 (IC95%: 0,58-0,78) e 0,70 (IC95%: 0,62-0,79), respectivamente, comparado com aqueles com consumo raro de verduras. Enquanto isso, as ORs ajustados foram 0,77 (IC95%: 0,64-0,92) e 0,80 (IC95%: 0,68-0,94), separadamente, para adultos com consumo eventual e diário de verduras para desenvolver uma PC única, comparado aos que relatavam consumo raro de verduras. Entretanto, não foi observada uma associação significativa entre consumo de frutas e PC. Entre a população chinesa com alto risco de DCV, o consumo de verduras frescas mostrou associação negativa com o risco de desenvolvimento de placa carotídea.

El objetivo de este estudio fue investigar la asociación del consumo de frutas y verduras con la placa carotídea (PC) y el grosor íntima-media carotídeo (GIMC), dos predictores de la aterosclerosis carotídea en adultos urbanos y rurales, con alto riesgo de desarrollar enfermedades cardiovasculares (ECV) en una región de China. Se identificaron, en este estudio transversal, a 11.392 adultos con alto riesgo de ECV dentro de una población general de 71.511, realizado entre noviembre de 2015 y mayo de 2016 en la provincia de Jiangsu. De estos 11.392 participantes en alto riesgo, la prevalencia de PC fue de un 36,7%. Las variables independientes, así como la frecuencia de consumo de verduras y fruta, se evaluaron mediante un cuestionario de frecuencia de comidas. Las variables de resultado, GIMC y PC, se midieron por un examen de ultrasonido. El análisis ANCOVA mostró que no existía asociación entre los valores GIMC y la frecuencia en el consumo de verduras y frutas. Los modelos de regresión logística multivariantes se introdujeron para examinar la asociación entre el consumo de verduras y frutas y la PC. Tras el ajuste para los factores potenciales de confusión, las ORs de haber tenido alguna PC para los participantes que ocasionalmente y diariamente consumían verduras fueron 0,67 (IC95%: 0,58-0,78) y 0,70 (IC95%: 0,62-0,79), respectivamente, comparadas con quienes raramente consumían verduras. Mientras que las ORs ajustadas fueron 0,77 (IC95%: 0,64-0,92) y 0,80 (IC95%: 0,68-0,94), separadamente, para los consumidores ocasionales y los consumidores diarios de verduras de desarrollar una única PC, en relación con sus contrapartes que raramente consumían verduras. No obstante, no se observó una asociación significativa entre el consumo de frutas y la PC. Entre la población con alto riesgo de ECV, el consumo de verdura fresca estuvo negativamente asociado con el riesgo de desarrollar PC.

Possible mechanisms underlying the association between human T-cell leukemia virus type 1 (HTLV-1) and hypertension in elderly Japanese population

BACKGROUND@#Human T-cell leukemia virus type 1 (HTLV-1) activates inflammatory cascades by activating the NF-κB pathway. The minor allele of single nucleotide polymorphism (SNP) in breast cancer suppressor BRCA1-associated protein (BRAP), which has a common etiology with HTLV-1 infection, has been reported to be positively associated with carotid atherosclerosis, but inversely associated with hypertension. Therefore, HTLV-1 infection may be inversely associated with hypertension by activating endothelial maintenance, including atherosclerosis. To clarify these associations, a cross-sectional study was conducted using 2989 Japanese individuals aged 60-99 years participating in a general health check-up.@*METHODS@#Logistic regression models were used to clarify the association between HTLV-1 and hypertension. Platelet levels stratified analyses were also performed since platelet production, which plays a crucial role in endothelium maintenance, can be stimulated by activating the NF-κB pathway.@*RESULTS@#HTLV-1 infection was found to be significantly inversely associated with hypertension, particularly in subjects with high platelet levels (≥ second tertiles of platelet levels); the fully adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were 0.75 (0.62, 0.92) for total and 0.64 (0.50, 0.82) for high platelet levels, respectively. Further analysis of the non-hypertensive subjects demonstrated that HTLV-1 infection was significantly positively associated with atherosclerosis in subjects with the highest tertile of platelet levels (2.11 [1.15, 3.86]) but not in subjects with low platelet levels (first and second tertiles of platelet level) (0.89 [0.57, 1.39]).@*CONCLUSION@#Asymptomatic HTLV-1 infection is inversely associated with hypertension, possibly by activating endothelial maintenance, including atherosclerosis progression.

Íntima media carotidea como predictor de enfermedad aterosclerótica en pacientes con psoriasis / Carotid intima media as a predictor of atherosclerotic diseasein psoriasis patients

La psoriasis es una enfermedad inflamatoria cutánea crónica, conocida como un desorden multisistémico. En pacientes con enfermedades inflamatorias crónicas se ha descrito una correlación directa entre el grosor de la arteria carótida común y el desarrollo de futuras complicaciones cardiovasculares. Algunos estudios han demostrado una correlación de psoriasis y el desarrollo de eventos cardiovasculares dado que tienen un riesgo aumentado de desarrollar enfermedad aterosclerótica. En Venezuela las enfermedades cardiovasculares se ubican como primera causa de muerte, y a pesar del creciente número de pacientes con psoriasis no se han llevado a cabo estudios que permitan determinar el papel de psoriasis y la enfermedad arterial coronaria. Por ello la presente investigación se planteó determinar la relación entre el grado de severidad de psoriasis y el grosor de la íntima media carotidea a un grupo de 20 pacientes con diagnóstico de psoriasis. Recopilada la información, se realizó la prueba de chi-cuadrado,considerando un contraste estadísticamente significativo si p< 0,05. El análisis de datos se hizo con JMP-SAS versión 12,obteniéndose como evidencia que existe asociación entre el grado de severidad de psoriasis y el espesor del grosor de la capa íntima media carotidea, por lo que se pudo predecir la existencia de enfermedad aterosclerótica subclínica(AU)

Psoriasis is a chronic inflammatory skin disease, known as a multi-system disorder. A direct correlation between the thickness of the common carotid artery and the development of future cardiovascular complications has been described in patients with chronic inflammatory diseases. Some studieshave shown a correlation of psoriasis and the developmentof cardiovascular events since they have an increased risk of developing atherosclerotic disease. In Venezuela, cardiovascular diseases are the leading cause of death, and despite the increasing number of patients with psoriasis, no studies have been carriedout to determine the role of psoriasis and coronary artery disease. There fore, the present investigation set out to determine the relationship between the degree of severity of psoriasis and thethickness of the carotid intima media in a group of 20 patientsdiagnosed with psoriasis. Once the information was collected, the chi-square test was performed, considering a statistically significant contrast if p <0.05. The data analysis was done withJMP-SAS version 12, obtaining as evidence that there is anassociation between the degree of severity of psoriasis and the thickness of the thickness of the carotid medial intima layer,so the existence of atherosclerotic disease could be predicted. subclinical(AU)

Prevalencia de lesiones ateroscleróticas carotídeas en radiografía panorámica y su relación con factores de riesgo cardiovascular en brasileños / Prevalence of atherosclerotic carotid lesions on panoramic radiography and relationship with cardiovascular risk factors in Brazilians

RESUMEN: Aunque la radiografía panorámica no es una prueba de diagnóstico inicial para detectar la aterosclerosis carotídea, no podemos ignorar su valor al ver estas lesiones como hallazgos incidentales que pueden ser grandes aliados en el diagnóstico temprano y la prevención de eventos vasculares graves. El objetivo de este estudio fue evaluar la prevalencia de calcificaciones en la bifurcación de la arteria carótida en las radiografías panorámicas de rutina como principio diagnóstico, así como su relación con los factores de riesgo cardiovascular en individuos brasileños. Se analizaron 449 exámenes de radiografía panorámica de la base de datos del Departamento de Radiología de la Facultad de Odontología de Piracicaba, UNICAMP, São Paulo, Brasil. Después de obtener mediciones de la presión arterial e información sobre el tabaquismo y las enfermedades sistémicas, fue buscado en la radiografía panorámica la presencia o ausencia de la masa radiopaca en las regiones de las vértebras cervicales C3-C4. En el caso de una imagen sugestiva de ateroma, se realizó una radiografía anteroposterior para confirmar el diagnóstico. Aplicamos la prueba estadística de Chi-cuadrado con distribución normal y muestras independientes y aleatorias con un intervalo de confianza del 95 %. La confirmación de calcificaciones carotideas se produjo en el 8,5 % de la población de estudio (38 casos). No encontramos ninguna relación entre la presencia de calcificaciones con el tabaquismo, con el sexo o con datos previos de antecedentes familiares. Sin embargo 49,1 % de los casos estaban por encima de sesenta años y tenía asociación significativa con la hipertensión (P = 0,006). El mayor riesgo se presenta en pacientes ancianos hipertensos y, por lo tanto, hacemos hincapié en la importancia de una observación minuciosa de las radiografías panorámicas en la búsqueda de cualquier alteración de la anatomía normal y si es así, proceder con la derivación lo antes posible para un diagnóstico concluyente por parte de un especialista, pudiendo así ayudar en la prevención de episodios vasculares graves.

SUMMARY: Although panoramic radiography is not an initial diagnostic test for detecting carotid atherosclerosis, we cannot ignore its value in viewing these lesions as incidental findings that can be great allies in early diagnosis and prevention of serious vascular events. The aim was to evaluate the prevalence of calcifications in the bifurcation of the carotid artery on routine panoramic radiographs as a diagnostic principle, as well as its relationship with cardiovascular risk factors in Brazilians. We analyzed 449 panoramic radiography exams from the database of the Department of Radiology of the Faculty of Dentistry of Piracicaba, UNICAMP, São Paulo, Brazil. After obtaining blood pressure measurements and information on smoking and systemic diseases, the researcher observed on the panoramic radiograph, the presence or absence of the radiopaque mass in the regions of the cervical vertebrae C3-C4. In the case of a suggestive image of atheroma, an anteroposterior radiography was performed to confirm the diagnosis. The Chi-square test of normal distribution for independent and random samples with a 95 % confidence interval was applied to the data. Confirmation of carotid calcifications occurred in 8.5 % of the study population (38 cases). We did not find any relationship between the presence of calcifications with smoking, sex or previous family history. However, 49.1 % of cases occurred above sixty years old and there was a significant relationship with hypertension (P = 0.006). The greatest risk was presented in elderly and hypertensive patients, so we highlight the importance of a thorough observation by the dentist of panoramic radiographs to detect any alteration of the normal anatomy and in the positive case, proceed with the referral as soon as possible for a conclusive diagnosis by a specialist, being able to thus assist in the prevention of severe vascular episodes.

Panoramic radiography for detection of bilateral carotid calcified atheroma: an unusual case report / Radiografía panorámica para la detección de ateroma calcificado carotídeo bilateral: reporte de un caso inusual

Introduction: Atherosclerosis is a progressive inflammatory disease that can trigger serious medical consequences like acute myocardial infarction or stroke. Case Report: The purpose of this study is to report an unusual case of finding calcified atheromatous plaques in the carotid arteries bilaterally using a panoramic radiography (PR). A 75-year-old female with a morbid history, attends the Teaching Dental Clinic of the Pontifical Catholic University with complementary exams. PR showed well-defined radiopaque structures adjacent to C4. Using a Doppler ultrasound, the presence of calcified atheromas in the right and left carotid arteries were confirmed. The patient was informed of these findings and is currently under medical follow-up. Conclusion: PR is a useful complementary resource in the detection of atherosclerotic plaques of the upper carotid region.

The role of monocyte to HDL ratio in predicting clinically significant carotid stenosis in patients with asymptomatic carotid artery disease

SUMMARY OBJECTIVE Monocyte count to HDL-C Ratio (MHR) and Fibrinogen to Albumin Ratio (FAR) have recently emerged as markers of inflammation in atherosclerotic diseases. Our goal was to investigate the relationships of MHR and FAR with the severity of carotid artery stenosis (CAS) in patients with asymptomatic carotid artery disease. METHODS This retrospective study consisted of 300 patients with asymptomatic CAS. Pre-angiographic MHR, FAR, and high-sensitive C-reactive protein (hsCRP) were measured. Carotid angiography was performed in patients with ≥50% stenosis on carotid ultrasonography. Patients were first split into 2 groups based on the degree of CAS and then tertiles (T) of MHR. RESULTS 96 patients had clinically insignificant CAS (<50%) (Group-1), and 204 patients had clinically significant CAS (≥50%) (Group-2). Group-2 had higher MHR, FAR, and hsCRP than group-1. Patients in T3 had higher MHR, FAR, and hsCRP than in T1 and T2. MHR, FAR, and hsCRP were correlated with each other (p<0.001, for all). MHR, FAR, and hsCRP were independent predictors of significant CAS. MHR better predicted a significant CAS than FAR and hsCRP (p<0.05). CONCLUSION Pre-angiographic MHR may be a better predictor than FAR and hsCRP in identifying a clinically significant carotid stenosis in patients with asymptomatic CAS. Patients with asymptomatic CAS and a high level of MHR should be followed-up closely to supervise risk-factor control and intensify treatment.

RESUMO OBJETIVO Recentemente, a contagem de monócitos para a proporção HDL-C (MHR) e a relação fibrinogênio para albumina (FAR) emergiram como marcadores de inflamação em doenças ateroscleróticas. Nosso objetivo é investigar a relação da MHR e FAR com a gravidade da estenose da artéria carótida (CAS) em pacientes com doença assintomática da artéria carótida. MÉTODOS Este estudo retrospectivo incluiu 300 pacientes com CAS assintomática. MHR pré-angiográfica, FAR e proteína C reativa de alta sensibilidade (hsCRP) foram medidas. A angiografia carotídea foi realizada em pacientes com estenose ≥50% na ultrassonografia carotídea. Os pacientes foram primeiramente divididos em dois grupos com base no grau de CAS e depois nos tercis (T) da MHR. RESULTADOS Noventa e seis pacientes apresentaram um CAS clinicamente insignificante (<50%) (grupo 1) e 204 pacientes apresentaram CAS clinicamente significativo (≥50%) (grupo 2). O grupo 2 apresentou MHR, FAR e hsCRP superior ao grupo 1. Pacientes em T3 apresentaram maior MHR, FAR e hsCRP do que em T1 e T2. MHR, FAR e hsCRP foram correlacionados entre si (p<0,001, para todos). MHR, FAR e hsCRP foram preditores independentes de CAS significativa. MHR predisse melhor uma CAS significativa que FAR e hsCRP (p<0,05). CONCLUSÕES A MHR pré-angiográfica pode ser um melhor preditor que a FAR e a hsCRP na identificação de estenose carotídea clinicamente significativa em pacientes com CAS assintomática. Pacientes com CAS assintomática e alto nível de MHR devem ser acompanhados de perto para supervisionar o controle dos fatores de risco e intensificar o tratamento.

Hemorragia digestiva masiva por fístulas secundarias de grandes vasos al tracto digestivo / Massive digestive hemorrhage from secondary fistulas of great vessels to the digestive tract

RESUMEN La formación de una fístula entre arterias de gran calibre y el tubo digestivo es una complicación infrecuente de la cirugía reconstructiva de los grandes vasos sanguíneos secundario al uso de prótesis vasculares, los cuales se manifiestan con hemorragias masivas con elevada mortalidad. Presentamos dos casos de fístula aorto-entérico y de fístula carotideo-esofágico que comparten características comunes como la manifestación clínica de hemorragia digestiva masiva y mortal en pacientes con antecedentes de colocación de prótesis vasculares.

ABSTRACT The formation of a fistula between large caliber arteries and the digestive tract is an uncommon complication of reconstructive surgery of the large vessels secondary to the use of vascular prostheses, which manifest themselves with massive hemorrhages with high mortality. We report two cases of aorto-enteric fistula and carotid-esophageal fistula that share common characteristics such as the clinical manifestation of massive and fatal gastrointestinal bleeding in patients with a history of vascular prosthesis placement.

Doença Arterial Coronariana Anatômica Associada à Quimioterapia em Pacientes com Câncer de Pulmão Avaliada pelo Escore Angiográfico SYNTAX / Chemotherapy-Related Anatomical Coronary-Artery Disease in Lung Cancer Patients Evaluated by Coronary-Angiography SYNTAX Score

Resumo Fundamento A doença arterial coronariana (DAC) associada à quimioterapia está se tornando um tema emergente na prática clínica. Contudo, o mecanismo subjacente da quimioterapia associada à DAC permanence incerto. Objetivos O estudo investigou a associação entre a quimioterapia e as anomalias anatômicas ateroscleróticas das artérias coronárias dentre pacientes com cancer de pulmão. Métodos Foram incluídos pacientes submetidos à angiografia coronária (AGC), entre 2010 e 2017, com câncer de pulmão prévio. Os fatores de risco associados à DAC e os dados sobre o câncer de pulmão foram avaliados. Avaliamos as anomalias das artérias coronárias de acordo com o escore SYNTAX (SXescore) calculado à AGC. Na análise de regressão logística, o escore SYNTAX foi classificado como alto (SXescoreALTO) se ≥22. Os dados foram analisados através de estatística descritiva e análise de regressão. Resultados Ao todo, 94 pacientes foram incluídos no estudo. O SXescore foi mais alto no grupo com quimioterapia quando comparado com o grupo sem quimioterapia (25,25, IIQ [4,50-30,00] versus 16,50, IIQ [5,00-22,00]; p = 0,0195). A taxa do SXescoreALTO foi maior no grupo com quimioterapia do que no no grupo sem quimioterapia (58,33% versus 25,86; p = 0,0016). Tanto a análise de regressão logística univariada (OR: 4,013; 95% IC:1,655-9,731) quanto a multivariada (OR: 5,868; 95% IC:1,778-19,367) revelaram que a quimioterapia aumentou o risco de uma maior taxa do SXescoreALTO. A análise multivariada de regressão logística Stepwise mostrou que o risco para DAC anatômica mais grave aumenta com a quimioterapia como um todo em 5.323 vezes (95% IC: 2,002-14,152), e com o regime à base de platina em 5,850 vezes (95% IC: 2,027-16,879). Conclusões A quimioterapia está associada com a complexidade e gravidade anatômica da DAC, o que pode explicar, em parte, o maior risco de DAC associada à quimioterapia dentre pacientes com câncer de pulmão.

Abstract Background Chemotherapy-related coronary artery disease (CAD) is becoming an emerging issue in clinic. However, the underlying mechanism of chemotherapy-related CAD remains unclear. Objective The study investigated the association between chemotherapy and atherosclerotic anatomical abnormalities of coronary arteries among lung cancer patients. Methods Patients undergoing coronary angiography (CAG) between 2010 and 2017, who previously had lung cancer, were examined. Risk factors associated with CAD and information about lung cancer were evaluated. We assessed coronary-artery abnormalities by SYNTAX score (SXscore) based on CAG. In logistic-regression analysis, we defined high SXscore (SXhigh) grade as positive if ≥22. Data were analyzed through descriptive statistics and regression analysis. Results A total of 94 patients were included in the study. The SXscore was higher in the chemotherapy group than in the non-chemotherapy group (25.25, IQR [4.50-30.00] vs. 16.50, IQR [ 5.00-22.00], p = 0.0195). The SXhigh rate was greater in the chemotherapy group than in the non-chemotherapy group (58.33% vs. 25.86; p = 0.0016). Both univariate (OR:4.013; 95% CI:1.655-9.731) and multivariate (OR:5.868; 95% CI:1.778-19.367) logistic-regression analysis revealed that chemotherapy increased the risk of greater SXhigh rates. Multivariate stepwise logistic-regression analysis showed the risk of more severe anatomical CAD is increased by chemotherapy as a whole by 5.323 times (95% CI: 2.002-14.152), and by platinum-based regimens by 5.850 times (95% CI: 2.027-16.879). Conclusions Chemotherapy is associated with anatomical complexity and severity of CAD, which might partly account for the higher risk of chemotherapy-related CAD among lung cancer patients.
