RESUMEN

ABSTRACT The occurrence of corneal ectasia after photorefractive keratectomy is a rare but serious complication of refractive surgery. Possible risk factors are not well assessed, but a probable reason is the failure to detect keratoconus preoperatively. In this report, we describe a case of corneal ectasia after photorefractive keratectomy in a patient who presented a suspicious tomography pattern preoperatively but had no degenerative alterations associated with pathologic keratoconus, as revealed by in vivo corneal confocal microscopy. We also review eligible case reports of post-photorefractive keratectomy ectasia to find similar characteristics.


RESUMO A ocorrência de ectasia corneana após ceratectomia fotorrefrativa é uma complicação rara, porém grave, em cirurgia refrativa. Os possíveis fatores de risco não são bem avaliados, mas a opinião atual é que a falha na detecção de ceratocone pré-operatório possa ser o principal motivo. Neste relato, descrevemos um caso de ectasia corneana após ceratectomia fotorrefrativa em paciente apresentando padrão tomográfico suspeito no pré-operatório, mas sem alterações degenerativas associadas a ceratocone patológico, conforme revelado por microscopia confocal in vivo da córnea. Além disso, revisamos, na literatura, relatos de casos elegíveis de ectasia pós-ceratectomia fotorrefrativa para encontrar características semelhantes.

RESUMEN

Abstract Background: Coronary artery ectasia (CAE) is defined by focal enlargement of the coronary artery exceeding 1.5 times the adjacent normal segment. CAE can often cause arrhythmias, heart failure, sudden death, and myocardial ischemia. Ischemia due to microvascular dysfunction may be responsible for the ventricular heterogeneity in CAE. Objectives: The aim of our study was to evaluate the frontal QRS-T angle in patients with CAE. Methods: Our study included 55 patients with CAE and 50 individuals in the control group. Demographic characteristics and electrocardiographic parameters were compared between the two groups. Categorical variables were compared using the chi-square test. Continuous variables were compared using unpaired Student's t-test. P values < 0.05 were considered statistically significant. The frontal QRS-T angle was calculated from 12-lead electrocardiograms (ECGs) using the automatic report from the electrocardiography machine. Results: The average age of patients with CAE was 63.2 ± 3.4 years, with 18 women among them. The control group had an average age of 61.1 ± 3.2 years, with 28 women included. There was no significant difference in demographic parameters between the two groups. Compared to the control group, patients with CAE had significantly wider frontal QRS-T angle (p < 0.001), as well as longer QTmax duration, p = 0.002; Tp-Te interval, p = 0.02; and QT dispersion (QTd), p = 0.04. Conclusion: The frontal QRS-T angle can be calculated easily and time-efficiently using surface electrocardiography. In this study, we showed for the first time that the frontal QRS-T angle was significantly increased in patients with CAE.

RESUMEN

Objective:To establish the reference values and neurological intervention cutoffs for cerebral ventricular size in neonates born at 33 +0-41 +6 weeks of gestation and to investigate the influential factors and reliability of the related indices. Methods:This study prospectively recruited 1 370 1-to 7-day neonates born or hospitalized at the Hunan Provincial Maternal and Child Health Care Hospital from February to August 2021. All the neonates, who were born between 33 +0 and 41 +6 weeks of gestation, were subjected to ultrasound scanning to obtain the indices, including ventricular index (VI), anterior horn width (AHW), thalamo-occipital distance (TOD), and ventricular height (VH). The reference value and neurological intervention cutoff for each index were set. Quantile regression was used to estimate the correlation between each index and continuous covariates [gestational age at birth (GA) and birth weight (BW)]. Mann-Whitney U test was used to analyze the differences in the medians of indices in different categorical covariates groups (males/females, left/right lateral ventricles, vaginal delivery/cesarean section, and singleton/multiple births). Intraclass correlation coefficient (ICC) calculated by a two-way mixed effect model and absolute agreement was used to access intra-rater reliability; ICC via a two-way random effect model and absolute agreement was utilized to rate inter-rater reliability (pool reliability: ICC below 0.50; moderate reliability: ICC between 0.50 and 0.75; good reliability: ICC between 0.75 and 0.90; excellent reliability: ICC exceeding 0.90). Results:The upper limits of reference values for AHW, TOD, VI, and VH in 555 (40.5%) preterm neonates were 2.7-3.5 mm, 20.9-22.5 mm, 12.6-13.7 mm, and 3.8-4.9 mm, and in 815 (59.5%) term newborns were 3.4-4.3 mm, 18.6-21.3 mm, 14.2-14.7 mm, and 3.4-3.8 mm, respectively. The cutoff of neurosurgical intervention for each index was the upper limit of reference value plus 4 mm. AHW median was positively correlated with GA [partial regression coefficient (PRC): 0.12, P<0.05], while TOD and VH medians were negatively correlated with GA (PRC:-0.31 and-0.06, both P<0.05). VI, AHW, and TOD medians were positively associated with BW (PRC: 0.46, 0.23, and 0.97, all P<0.05). The medians of VH, AHW, and TOD in the left cerebral ventricular exceeded those in the right cerebral ventricular, respectively (VH: 2.0 vs 1.8 mm, U=836 071.50; AHW: 1.8 vs 1.7 mm, U=874 141.50; TOD: 13.6 vs 12.5 mm, U=738 409.00, all P<0.05). The medians of AHW and VI in male neonates were greater than those in female newborns, respectively (AHW: 1.8 vs 1.7 mm, U=834 124.00; VI: 11.1 vs 10.8 mm, U=884 156.50, both P<0.05). The neonates delivered vaginally had greater AHW median, but smaller TOD median than those delivered by cesarean section (AHW: 2.0 vs 1.6 mm, U=685 546.00, P<0.001; TOD: 13.1 vs 12.9 mm, U=850 797.00, P=0.010). The AHW median in singleton newborns exceeded that in multiple births (1.9 vs 1.4 mm, U=356 999.00, P<0.001). The lower limits of 95% confidence intervals for intra-rater and inter-rater ICCs exceeded 0.75 and 0.50, respectively. Conclusion:Reference values and surgical intervention thresholds for VI, AHW, TOD, VH of newborns with a gestational age of 33 +0-41 +6 weeks were preliminarily established, and the reliability of these indicators were verified.

RESUMEN

RESUMO Objetivo Identificar alterações de aberrometria de alta ordem em diferentes graus de ceratocone. Métodos Estudo transversal, retrospectivo, observacional. Foram analisados 54 pacientes (108 olhos) diagnosticados com ceratocone pelo mesmo especialista em córnea por meio dos critérios ABCD de Belin/Ambrósio Enhanced Ectasia, utilizando-se o tomógrafo Pentacam® HR 70900 (Oculus Wetzlar, Alemanha). Além disso, foram feitas análises qualitativa e quantitativa das aberrações de alta ordem desses mesmos pacientes por meio do OPD-Scan III-NIDEK. Resultados Por meio da avaliação de ambos os olhos dos pacientes com os critérios de Belin-Ambrósio, constatou-se presença de ceratocone em 34 pacientes. Ademais, por meio da análise estatística, constatou-se relação direta entre a asfericidade posterior e o desenvolvimento do ceratocone, com p<0,001 (referência: p<0,05). Por meio da análise do OPD-Scan III-NIDEK, as principais aberrações de alta ordem encontradas nos pacientes com ceratocone foram coma, trefoil e aberração esférica. Conclusão O raio da curvatura posterior é a primeira variável a se alterar com o desenvolvimento do ceratocone, o que se faz perceptível na análise da asfericidade posterior por meio o Pentacam®. Além disso, a alteração da paquimetria e da asfericidade posterior influencia diretamente o desenvolvimento de aberrações de alta ordem em pacientes com ceratocone.


ABSTRACT Objective To identify higher order aberrometry changes in different degrees of keratoconus. Methods Cross-sectional, retrospective, observational study. Fifty-four patients (108 eyes) diagnosed with keratoconus by the same corneal specialist using the Belin/Ambrósio Enhanced Ectasia ABCD criteria were analyzed, using the Pentacam® HR 70900 tomograph (Oculus Wetzlar, Germany). In addition, qualitative and quantitative analysis of higher order aberrations in these patients was performed using the OPD-Scan III-NIDEK. Results Through the evaluation of both eyes of the patients according to the criteria of Benin Ambrósio, the presence of KCN was verified in 34 patients. Furthermore, through statistical analysis, a direct relationship was found between posterior asphericity and the development of KCN; p<0.001 (reference: p<0.05). Through the analysis of the OPD scan, the main higher order aberrations found in patients with KCN were Coma, Trefoil and Spherical Aberration (AE). Conclusion The posterior curvature radius is the first variable to change with the development of the KCN, which is noticeable in the analysis of posterior asphericity in Pentacam. In addition, alterations in pachymetry and posterior asphericity directly influence the development of higher order aberrations in patients with KCN.

RESUMEN

Resumo Fundamento A patologia subjacente da ectasia da artéria coronária (EC) isolada não foi totalmente elucidada. Objetivo Nosso objetivo foi examinar a relação entre o índice de inflamação imune sistêmica (Sıı), que corresponde à multiplicação da razão neutrófilos-linfócitos (RNL) e as contagens de plaquetas, e EC isolada. Método A população do estudo retrospectivo incluiu 200 pacientes com EC isolada, 200 consecutivos com doença arterial coronariana obstrutiva e 200 consecutivos com angiografia coronária normal. Um valor de p bicaudal <0,05 foi considerado significativo. Resultados Sıı, RNL, razão plaqueta-linfócito (RPL) e razão monócito-colesterol de lipoproteína de alta densidade (MHR) foram significativamente maiores no grupo EC em comparação com os outros grupos (todos p<0,001). Na análise multivariada, Sıı (p<0,001, OR = 1,005, IC 95% =1,004-1,005) foi considerado um preditor independente de EC isolada. Na análise da curva Receiver Operating Characteristic (ROC), Sıı teve uma área sob a curva maior em comparação com RNL, RPL e MHR. O valor de Sıı >517,35 tem 79% de sensibilidade, 76% de especificidade para a predição do EC [AUC: 0,832, (p<0,001)]. Sıı teve correlação significativa com o número de artérias coronárias ectásicas e classificação de Markis (r: 0,214 p=0,002; r:-0,195, p=0,006, respectivamente). Conclusão Até onde sabemos, este é o primeiro estudo em que Sıı foi significativamente associado à presença isolada de EC e gravidade anatômica.


Abstract Background The underlying pathology of isolated coronary artery ectasia (CE) has not been fully elucidated. Objective We aimed to examine the relationship between the systemic immune inflammation index (Sıı), which corresponds to the multiplying of the neutrophil-to-lymphocyte ratio (NLR) and the platelet counts, and isolated CE. Method The retrospective study population included 200 patients with isolated CE, 200 consecutive with obstructive coronary artery disease, and 200 consecutive with a normal coronary artery angiogram. A 2-sided p-value of <0.05 was considered significant. Results Sıı, NLR, platelet-to-lymphocyte ratio (PLR), and monocyte-to-high density lipoprotein cholesterol ratio (MHR) were significantly higher in the CE group compared with the other groups (all p<0.001). In multivariate analysis, Sıı (p<0.001, OR = 1.005, 95% CI =1.004-1.005) was found to be an independent predictor of isolated CE. In Receiver Operating Characteristic curve analysis, Sıı had a higher Area Under the Curve than NLR, PLR, and MHR. Sıı value of >517.35 has 79% sensitivity, 76% specificity for the prediction of the CE [AUC: 0.832, (p<0.001)]. Sıı had a significant correlation with the number of ectatic coronary arteries and Markis classification (r:0.214 p=0.002; r:-0.195, p=0.006, respectively). Conclusion To the best of our knowledge, this is the first study that Sıı was significantly associated with isolated CE presence and anatomical severity.

RESUMEN

Resumo O infarto do miocárdio com artérias coronárias não obstrutivas (MINOCA) é um fenômeno clínico intrigante e de prognóstico incerto, caracterizado pela evidência de infarto do miocárdio (IM) com artérias coronárias normais ou quase normais na angiografia1. Atualmente, não há diretrizes para o manejo e muitos pacientes recebem alta sem uma etiologia determinada, significando muitas vezes que o tratamento ideal é adiado.Relatamos três estudos de caso MINOCA com as principais causas fisiopatológicas cardíacas, particularmente epicárdicas, microvasculares e não isquêmicas, levando ao tratamento diferencial. Os pacientes apresentavam dor torácica aguda, aumento da troponina e nenhuma doença coronariana angiograficamente significativa.Neste estudo, analisamos a etiologia, diagnóstico clínico e tratamento da MINOCA em relação à literatura relevante.MINOCA é considerado um diagnóstico de trabalho dinâmico, incluindo distúrbios coronários, miocárdicos e não coronários. Estudos prospectivos e registros são necessários para melhorar o atendimento e o resultado do paciente.


Abstract Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a puzzling clinical phenomenon with an unclear prognosis, characterized by evidence of myocardial infarction (MI) with normal or near-normal coronary arteries on angiography1. Currently, there are no guidelines for management, and many patients are discharged without a determined etiology, often meaning that optimal treatment gets postponed.We report three MINOCA case studies with main pathophysiological cardiac causes, particularly epicardial, microvascular, and non-ischemic, prompting differential management. The patients presented with acute chest pain, troponin raise, and no angiographically significant coronary disease.In this study, we analyzed the etiology, clinical diagnosis, and treatment of MINOCA concerning the relevant literature.MINOCA is considered to be a dynamic working diagnosis, including coronary, myocardial, and non-coronary disorders. Prospective studies and registries are needed to improve patient care and outcome.

RESUMEN

Kawasaki disease, an acute febrile illness, can cause vasculitis in the coronary arteries. It is the chief acquired cause of myocardial infarction and sudden cardiac death in infants, children, and young adults in developed countries. We report a case of chronic, silent Kawasaki disease complicated by multivessel thrombosis in a 39-year-old Egyptian woman. The patient presented with progressive, unstable angina but was otherwise asymptomatic and at negligible risk of ischemic heart disease. Coronary angiograms showed critical arterial stenosis with multiple aneurysms. During revascularization surgery, the patient's harvested left internal mammary artery was found to have occlusive lesions and aneurysmal areas that made it unfit for bypass grafting, and subsequent histopathologic examination revealed features characteristic of chronic Kawasaki disease-associated systemic vasculitis. We think that this is only the second report of Kawasaki disease in the Arabian Mediterranean region. In addition to the patient's case, we discuss the epidemiology and management of Kawasaki disease, in hopes of increasing clinicians' awareness.

RESUMEN

OBJECTIVE: The aim of the present comprehensive review was to present an overview of the clinical presentation and treatment options for external (EJVAs) and internal jugular vein aneurysms (IJVAs) to help clinicians in evidence-based decision making. METHODS: A systematic literature search was conducted in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement and included MEDLINE, Embase, Cochrane Library, Scopus, WHO (World Health Organization) trial register, ClinicalTrials.gov, and the LIVIVO search portal. The inclusion criteria were studies of patients who had presented with IJVAs or EJVAs. The exclusion criteria were animal and cadaver studies and reports on interventions using the healthy jugular vein for access only (ie, catheterization). Analysis of the pooled data from all eligible case reports was performed. RESULTS: From 1840 identified reports, 196 studies were eligible. A total of 256 patients with JVAs were reported, with 183 IJVAs and 73 EJVAs. IJVAs were reported to occur in 66% on the right side compared with the left side (P = .011). The patients with IJVAs were mostly children (median age, 12 years; interquartile range, 5.8-45.2 years). The patients with EJVAs were young adults (median age, 30 years; interquartile range, 11.0-46.5 years). EJVAs were more frequently reported in women and IJVAs in men (P = .008). Most of the patients were asymptomatic. Pulmonary embolization in association with thrombosed EJVAs was only reported for one patient. A report of the outcomes after surgery and conservative management was missing for ∼50% of the patients. No relevant complications were reported after ligation of the EJVA without reconstruction. Intracranial hypertension after ligation of the right-sided IJVA was reported in three children; in one of them, a pontine infarction was observed. CONCLUSIONS: JVAs are a disease of the younger population but can occur at any age. It seems to be safe to observe patients with nonthrombosed JVAs. However, in the presence of thrombus or pulmonary embolization, surgical treatment should be considered. A reconstruction technique of the IJVA with venous patency preservation should be preferred.

RESUMEN

Resumo Fundamento: A rigidez arterial é um importante preditor de aortopatia e remodelamento miocárdico em pacientes com válvula aórtica bicúspide, podendo estar aumentada na infância. Objetivo: Avaliar a rigidez arterial e a função miocárdica do ventrículo esquerdo em crianças com válvula aórtica bicúspide funcional. Métodos: Quarenta e quatro crianças com válvula aórtica bicúspide e 41 pares saudáveis com válvula aórtica tricúspide foram incluídos neste estudo caso-controle. Foram obtidos os diâmetros e os escores-z relacionados da raiz aórtica e da aorta ascendente. Quanto à função miocárdica do ventrículo esquerdo, juntamente com as velocidades de fluxo mitral e parâmetros do Modo M, as velocidades miocárdicas e os intervalos de tempo foram avaliados com Doppler tecidual. A análise da onda de pulso foi realizada por aparelho oscilométrico (Mobil-o-Graph). Um valor de p<0,05 foi considerado significativo. Resultados: O índice da massa ventricular esquerda, a velocidade A do fluxo mitral, o diâmetro e o escore z da aorta ascendente e o índice de desempenho miocárdico estavam significativamente maiores nos pacientes (p = 0,04, p = 0,02, p = 0,04, p <0,001 e p <0,001 respectivamente). O índice de desempenho miocárdico correlacionou-se positivamente com o diâmetro da aorta ascendente e a velocidade A (r=0,272; p=0,01, r=356; p=0,001, respectivamente). A análise multivariada revelou que o índice de desempenho miocárdico estava relacionado ao diâmetro da aorta ascendente (p = 0,01). O índice de aumento e a velocidade da onda de pulso foram semelhantes entre os grupos (p> 0,05). Conclusão: De acordo com a análise da onda de pulso oscilométrico, as crianças com válvula aórtica bicúspide funcional apresentam rigidez arterial semelhante a seus pares saudáveis. O diâmetro da aorta ascendente foi estabelecido como preditor independente da função miocárdica do ventrículo esquerdo. A rigidez arterial pode não ser um fator de risco grave em pacientes pediátricos sem dilatação acentuada da aorta ascendente.


Abstract Background: Arterial stiffness is an important predictor factor of aortopathy and myocardial remodeling in patients with a bicuspid aortic valve and it might be increased in childhood. Objective: To assess the arterial stiffness and left ventricular myocardial function in children with a well-functioning bicuspid aortic valve. Methods: Forty-four children with a bicuspid aortic valve and 41 healthy peers with a tricuspid aortic valve were included in this case-control study. Diameters and the related z-scores of the aortic root and ascending aorta were obtained. As for the left ventricular myocardial function, along with the mitral inflow velocities and M-Mode parameters, myocardial velocities and time intervals were assessed with tissue Doppler imaging. A pulse wave analysis was performed by oscillometric device (Mobil-o-Graph). A p value <0.05 was considered significant. Results: The left ventricular mass index, mitral inflow A velocity, diameter and z-score of the ascending aorta, and myocardial performance index were significantly higher in patients (p=0.04, p=0.02,p=0.04, p<0.001,and p<0.001 respectively). The myocardial performance index was positively correlated with the diameter of the ascending aorta and A velocity (r=0.272;p=0.01, r=356;p=0.001, respectively). The multivariate analysis revealed that the myocardial performance index was related to the ascending aorta diameter (p=0.01). The augmentation index and pulse wave velocity were similar between the groups (p>0.05). Conclusion: According to the oscillometric pulse wave analysis, the children with a well-functioning bicuspid aortic valve had similar arterial stiffness to that of the healthy peers. The ascending aorta diameter was established as an independent predictor of left ventricular myocardial function. Arterial stiffness may not be a severe risk factor in pediatric patients without marked ascending aorta dilation.

RESUMEN

RESUMO O artigo tem como objetivo descrever de forma prospectiva diferentes casos de ectasias altamente assimétricas (very asymmetric ectasia, VAE) para diferenciar formas subclínicas ou "frustas" do ceratocone (forme fruste keratoconus - FFKC) de casos de doença ectásica unilateral. O Caso 1 é um paciente de 39 anos, que admitiu ter coçado intensamente apenas o olho direito (OD) na juventude, se apresentando com ectasia unilateral tratada com sucesso por meio de implante de anel intraestromal em OD. O olho esquerdo (OE) apresentou-se normal ao exame completo por meio de propedêutica multimodal e acuidade visual não corrigida (AVsc) de 20/20, estável por mais de 5 anos, com TBI (tomography and biomechanical index) de 0.02. No Caso 2 é um paciente de 15 anos com ectasia clínica em OD, e OE com topografia normal, mas alterações tomográficas e biomecânicas, incluindo o TBI 0,56, caracterizarando a doença subclínica (FFKC). O Caso 3 é a mãe do paciente do Caso 2, de 46 anos, que se apresentou com presbiopia, sem qualquer histórico oftalmológico relevante. A AVsc foi de 20/20 em cada olho, topografia de Placido com leve encurvamento inferior, mas sem sinais definitivos de ectasia. A avaliação biomecânica e tomográfica revelou sinais de ceratocone em ambos os olhos, com TBI de 1,0 e 0,99. Esses três casos estão de acordo com a definição do consenso global e a hipótese de dois acertos (two-hit hypothesis), que ceratocone é uma doença bilateral, mas ectasia pode ocorrer por causa estritamente mecânica unilateralmente (ou em qualquer olho). A relevância da propedêutica multimodal é destacada, destacando-se a integração do estudo biomecânico e tomográfico com imagens de Scheimpflug.


ABSTRACT The article aims to prospectively describe different cases of highly asymmetric ectasia (very asymmetric ectasia, VAE) to differentiate subclinical or "frustrated" forms of keratoconus (forme fruste keratoconus - FFKC) from cases of unilateral ectatic disease. Case 1 is a 39-year-old patient with unilateral ectasia treated with an intrastromal ring implant. The contralateral eye was normal due to multimodal propaedeutics, stable for more than 3 years, with a TBI of 0.02. The patient admitted to having intensely scratched only his right eye in his youth. In Case 2, a 15-year-old patient with clinical ectasia in the right eye, had a left eye with normal topography and tomographic and biomechanical changes characterizing FFKC. Case 3 is the mother of the case 2 patient, aged 46, who presented with presbyopia, without any relevant ophthalmological history. Uncorrected visual acuity of 20/20 in each eye, Placido topography with slight lower curving, but without definitive signs of ectasia. The biomechanical and tomographic evaluation revealed signs of keratoconus in both eyes. These three cases are in accordance with the definition of the global consensus: keratoconus is a bilateral disease, but ectasia can occur because of strictly mechanical unilateral (in any eye). The relevance of multimodal refractive imaging is highlighted, with a focus on integrating biomechanical and tomographic assessments with Scheimpflug images.

RESUMEN

Resumo Fundamento A ectasia da artéria coronária (EAC) é definida como a dilatação difusa ou localizada do lúmen da artéria coronária com diâmetro de 1,5 a 2,0 vezes o diâmetro da artéria coronária normal adjacente. A relação proteína C-reativa/albumina (CAR, sigla em inglês) é um marcador inflamatório útil que tem sido documentado em doença arterial coronariana. Objetivo Analisar a associação entre a EAC e a CAR. Métodos Um protocolo caso-controle foi utilizado neste estudo. Foram incluídos 102 pacientesconsecutivos com EAC isolada sem estenose (56 homens e 46 mulheres; idade média de 60,4 ± 8,8 anos). O grupo controle era constituido pelo mesmo número de pacientes pareados por sexo e idade com artérias coronárias normais (55 homens e 47 mulheres; idade média de 61,2 ± 9,1 anos). Características clínicas, achados laboratoriais e histórico de uso de medicamentos foram registrados. Foram realizados teste t de Student, teste U de Mann-Whitney, teste do qui-quadrado, análise de regressão linear e logística. Foi considerado estatisticamente significativo p bilateral < 0,05. Resultados A CAR estava aumentada nos pacientes com EAC em comparação com os controles (32 e 16; p < 0,001). Além disso, foi verificado que a CAR era um preditor independente da EAC (razão de chances = 2,202; intervalo de confiança 95%, 1,184 - 5,365; p < 0,001). Conclusão No presente estudo, determinamos que os níveis da CAR estavam significativamente mais altos no grupo EAC que no grupo controle e a CAR estava significativamente correlacionada com a EAC.

Abstract Background Coronary artery ectasia (CAE) is defined as diffuse or localized dilatation of coronary artery lumen with a diameter of 1.5 to 2.0 times the adjacent normal coronary artery. The C-reactive protein to albumin ratio (CAR) is a useful inflammatory marker, which has been documented in coronary artery disease. Objective To analyze the association of CAE and CAR. Methods A case-control protocol was used in this study. We included 102 consecutive patients with isolated CAE without stenosis (56 men and 46 women; mean age 60.4 ± 8.8 years). The control subjects consisted of an equal number of sex and age matched patients with normal coronary arteries (55 men and 47 women; mean age 61.2 ± 9.1 years). Clinical features, laboratory findings, and medication use history were recorded. Student's t test, Mann-Whitney U test, chi-square test, and linear and logistic regression analysis were performed. A 2-sided p < 0.05 was statistically considered significant. Results The CAR was increased in patients with CAE compared to the controls (32 and 16; p < 0.001). In addition, the CAR was found to be an independent predictor of CAE (OR = 2.202; 95% CI 1.184 - 5.365; p < 0.001). Conclusion In the present study, we determined that CAR levels were significantly higher in the CAE group than in the control group, and the CAR was significantly correlated with CAE.

RESUMEN

Intracranial arterial dolichoectasia (IADE), also known as dilated cerebral artery disease, is a kind of disease in which the diseased arteries are lengthened, enlarged, and tortuous due to various reasons. Cerebral small vessel disease (CSVD) refers to a series of clinical, imaging and pathological syndromes caused by various etiologies affecting cerebral arterioles, venules and capillaries. Its main imaging manifestations include lacunar infarction, cerebral microbleeds, enlargement of perivascular space, white matter hyperintensities, and brain atrophy. In recent years, more and more studies have shown that IADE is closely associated with the occurrence and development of CSVD. This article reviews the correlation between IADE and CSVD.

RESUMEN

Objective: To investigate the effect of corneal diameter on Belin/Ambrósio enhanced ectasia display (BAD). Methods: Retrospective case series study. The subjects were 6 744 myopic patients, including 3 341 males and 3 403 females, who had undergone corneal refractive surgery or had completed preoperative examination but had not undergone corneal refractive surgery at the Army Medical Center and Chongqing Vision Institute in Chongqing from June 2017 to June 2019. Age was (23.74±5.73) years old. No patients had keratoconus. One eye of each patient was randomly included, and the patients were divided into groups according to the corneal diameter measured by Pentacam. Group A included 630 patients (630 eyes) with corneal diameter ≤ 11.1 mm. In group B, there were 4 063 patients (4 063 eyes) with corneal diameter of 11.2 to 11.8 mm. In group C, there were 2 051 patients (2 051 eyes) with corneal diameter ≥11.9 mm. Preoperative BAD parameters of deviation of front elevation difference map (Df), deviation of back elevation difference map (Db), deviation of average pachymetric progression index (Dp), deviation of minimum thickness (Dt), deviation of Ambrósio's relational thickness maximum (Da) and overall deviation value (Do) were measured by Pentacam. One-way analysis of variance was used for preoperative BAD parameters comparison between groups. The distribution of normal, suspicious and pathological results of Df, Db, Dp, Dt, Da and Do in each group was tested by chi-square test. Results: In groups A, B and C, Df was 0.73±1.14, 0.48±1.02, and 0.11±0.91, Db was 1.09±1.07, 0.23±0.83, and-0.34±0.62, Dp was 1.57±0.91, 1.14±0.86, and 0.68±0.75, Dt was -0.11±0.84, -0.2±0.82, and 0.03±0.78, Da was 0.78±0.61, 0.64±0.64, and 0.48±0.64, and Do was 1.65±0.64, 1.24±0.60, and 0.86±0.55, respectively. The BAD parameters of Df (F=129.549), Db (F=829.491), Dp (F=344.373), Dt (F=7.249), Da (F=68.637) and Do (F=524.877) were all significantly different between groups (P<0.01). The proportion of suspicious and pathological BAD parameters [Df (χ²=161.8), Db (χ²=611.75), Dp (χ²=478.84), Da (χ²=44.636), and Do (χ²=553.11)] suggested the distribution in each group was significantly different (P<0.01). Conclusions: Corneal diameter had a significant influence on BAD. Compared with eyes with large corneas, the false positive rate of BAD was higher in eyes with small corneas.(Chin J Ophthalmol, 2020, 56: 761-767).

RESUMEN

Abstract Aneurysms of the sinuses of Valsalva are defined as dilatation of the aortic root region between the aortic annulus and the sinotubular junction. Isolated aneurysms of the sinus of Valsalva are rare cardiovascular pathologies. They may be congenital, especially secondary to connective tissue disorders or in conjunction with congenital cardiac defects, or acquired such as secondary to infections or trauma. Small sized aneurysm without rupture in asymptomatic patients may be followed; however, latter cases require intervention and surgery is the gold standard treatment modality. In this report, a 41-year-old male patient was reported with giant aneurysm of the non-coronary sinus of Valsalva whom underwent aortic root sparing surgical aortic sinus of Valsalva reconstruction.

RESUMEN

We evaluated aortic tissue specimens from patients undergoing tetralogy of Fallot repair, to determine whether histologic abnormalities affect postsurgical aortic remodeling and other patient-related variables. Using light microscopy, we studied full-thickness aortic wall tissue operatively excised from 118 consecutive patients undergoing intracardiac repair of tetralogy of Fallot. We performed multiple linear regression analysis to identify independent predictors of change in aortic root dimensions, which we measured with echocardiography after repair and every 3 months thereafter. Thirty histologically normal specimens were used as controls. Elastic fiber fragmentation was found in 74.6% of the abnormal specimens, mucoid extracellular matrix accumulation in 49.2%, smooth muscle cell nuclei loss in 39%, smooth muscle cell disorganization in 28.8%, and medial fibrosis in 52.5%. At a mean follow-up time of 83.55 ± 42.08 months, mean aortic sinotubular diameter decreased from 28.79 ± 9.15 to 27.16 ± 8.52 mm/m2 (r =-0.43; P <0.001). Aortic sinotubular diameter decreased by 0.6 mm/m2 among females (ß =0.6, SE=0.31; P =0.05) and by 0.88 mm/m2 in patients who had elastic fiber fragmentation or loss (ß =0.88, SE=0.38; P =0.02). In bivariate and multiple linear regression analysis, duration of follow-up emerged as an independent predictor of aortic remodeling. The aortic histopathologic changes in our patients had an independent negative impact on the degree of aortic remodeling after surgery. We observed the most improved aortic sinotubular diameter in patients who had either histologically normal aortas or aortas with elastic fragmentation.

RESUMEN

BACKGROUND: Patients with bicuspid aortic valve (BAV) have a higher risk of developing aortic valve dysfunction and progressive proximal aorta dilatation, which can lead to aortic dissection. To this day, identification of children at risk of developing severe aortic dilatation during their pediatric follow-up is still challenging because most studies were restricted to adult subjects. The overarching goal of this study was to identify risk factors of aortic dilatation in children with BAV. METHODS: We extracted clinical and echocardiographic data of all BAV subjects aged 0 to 20 years followed at Centre Hospitalier Universitaire Sainte-Justine between 1999 and 2016. We excluded subjects with concomitant heart defects and conditions affecting proximal aorta dimensions. Proximal aorta diameters (expressed as Z scores) were modeled in relation to age and potential predictive variables in a linear mixed model. The primary outcome was the rate of dilatation. RESULTS: We included 761 subjects (3134 echocardiograms) in final analyses. The mean ascending aorta Z score progression rate for BAV patient with a normally functioning aortic valve was estimated at 0.05 Z score unit per year. The strongest predictors of an increased dilatation rate were severe aortic stenosis, moderate and severe aortic regurgitation, and uncorrected coarctation of the aorta. Aortic valve leaflet fusion pattern and sex were not associated with progression rate. CONCLUSIONS: Children with a normally functioning BAV exhibited a very slow proximal aorta dilatation rate. Ascending aorta dilatation rate was significantly increased in patients with more than mild aortic valve dysfunction but was independent from BAV leaflet fusion type.

RESUMEN

Background: Coronary artery ectasia (CAE) is a rare condition with unclear pathophysiology, optimal treatment, and prognosis. We aimed to determine the prognostic implications of CAE following coronary angioplasty. Methods: We conducted a retrospective cohort study on 385 patients, including 87 subjects with CAE, who underwent percutaneous coronary intervention (PCI). Major adverse cardiovascular events (MACE) were considered to consist of mortality, nonfatal myocardial infarction (MI), repeated revascularization, and stroke. Results: The mean age of the participants was 57.31±6.70 years. Multivariate regression analysis revealed that patients with diabetes, ST-segment-elevation MI at presentation, and high thrombus grades were more likely to have suboptimal post-PCI thrombolysis in myocardial infarction (TIMI) flow. However, CAE was not a predictor of a decreased TIMI flow (OR: 1.46, 95% CI: 0.78-8.32; P=0.391). The Cox-regression model showed that CAE, the body mass index, and a family history of MI were risk factors for MACE, while short lesion lengths (<20 vs >20 mm) had an inverse relationship. The adjusted hazard ratio (HR) for the prediction of MACE in the presence of CAE was 1.65 (95% CI: 1.08-4.78; P=0.391). All-cause mortality (HR: 1.69, 95% CI: 0.12-3.81; P=0.830) and nonfatal MI (HR: 1.03, 95% CI: 0.72-4.21; P=0.341) occurred similarly in the CAE and non-CAE groups. Conversely, CAE increased urgent repeat revascularization (HR: 2.40; 95% CI: 1.13-5.86; P=0.013). Conclusion: Although CAE had no substantial short-term prognostic effects on post-PCI TIMI flow, considerable concerns regarding adverse outcomes emerged during our extended follow-up. Stringent follow-ups of these patients should be underscored due to the high likelihood of urgent revascularization.
