ABSTRACT

OBJECTIVE: To characterize demographically and clinically the patients with anaphylaxis treated in a third level health institution in Medellin, Colombia. METHODS: A cross-sectional descriptive observational study was carried out, which includedpatients were diagnosed with anaphylaxis between 2009 and 2019. Information was retrieved from medical records through a collection instrument. Subsequently, a descriptive statistical analysis of proportions and measures of central tendency of the variables of interest was performed. RESULTS: A total of 1820 records were reviewed and data from 253 patients were included. Among the reported comorbidities, drug allergy was the most prevalent (28%). The most frequent manifestations of anaphylaxis were cutaneous and respiratory. Most of the cases presented basal tryptase values ≤ 11.4 ng/mL (94.7%). Different etiological agents (food, drugs, insects and latex) were reported, and their frequency varied according to age. Adrenaline, steroids, and antihistamines were the treatments of choice in 39.9, 34.3, and 39.9% of cases, respectively. CONCLUSIONS: The characteristics of anaphylaxis in a medical center in Colombia coincide with those reported in Latin American. The treatment of anaphylaxis is not standardized, which makes it necessary to educate the health personnel and develop national guidelines.


OBJECTIVO: Identificar las características clínicas y demográficas de pacientes con anafilaxia, atendidos en un hospital de tercer nivel de Medellín, Colombia. MÉTODOS: Estudio observacional, descriptivo, de corte transversal, al que se incluyeron pacientes con diagnóstico con anafilaxia entre 2009 y 2019. La información de los pacientes se obtuvo a partir de los expedientes clínicos, mediante un instrumento de recolección. Se realizó un análisis estadístico descriptivo, de proporciones y medidas de tendencia central de las variables de interés. RESULTADOS: Se revisaron 1820 expedientes y se incluyeron los datos de 253 pacientes. Los agentes etiológicos más frecuentes fueron: medicamentos (52.1%), alimentos (34.7%), picadura de insectos (13.8%) y agentes no especificados (17.7%). Las manifestaciones cutáneas y respiratorias fueron las más frecuentes asociadas con anafilaxia. El 94.7% de los casos tuvo concentraciones normales de triptasa. La adrenalina, los corticosteroides y antihistamínicos fueron los fármacos de elección en el 39.9, 34.3 y 39.9% de los casos, respectivamente. CONCLUSIONES: Las características de anafilaxia coinciden con las reportadas en la mayor parte de los estudios en Latinoamérica. Aunque existen guías mundiales de tratamiento de la anafilaxia, no suelen aplicarse de forma uniforme, lo que hace necesario adiestrar al personal de salud y desarrollar guías nacionales al respecto.

ABSTRACT

BACKGROUND: Patients with allergic rhinitis to house dust mites have an increased risk of shrimp allergy. Der p 10 is a candidate biomarker to predict the risk of shrimp allergy among allergic rhinitis patients. OBJECTIVES: The aim of this study was to evaluate the diagnostic performance of anti-Der p 10 IgE as a predictor of shrimp allergy. METHODS: A nested case-control study was carried out with eighty-six allergic rhinitis patients sensitized to mite (Dermatophagoides pteronyssinus) and shrimp (Litopenaeu vannamei). Cases and controls were defined by anti-Der p 10 IgE results. Oral challenge with shrimp was used as the gold standard for the evaluation of diagnostic performance. RESULTS: All shrimp oral challenge test (OCT)-positive patients were positive for IgE against Der p 10. The level of anti-Der p 10 IgE >1.2 kUA/mL had the best diagnostic performance (sensitivity 100%, specificity 65%) Conclusion: Anti-Der p 10 IgE is useful for predicting shrimp allergy diagnosis and could reduce the requirement of an OCT.

ABSTRACT

La atrofia cerebral es un hallazgo común en pacientes con infección por el virus de la inmunodeficiencia humana, especialmente en pacientes con demencia; lo que demuestra compromiso neocortical en estadios tardíos de la enfermedad y compromiso de los ganglios basales en las fases tempranas o asintomáticas. Objetivo: Evaluar los cambios en el volumen cerebral total, el volumen del núcleo caudado, el volumen del núcleo accumbens y la anisotropía fraccional de los tractos de sustancia blanca en pacientes con VIH sin síntomas neurodegenerativos, en relación con sujetos sanos. Métodos: Para la segmentación y cuantificación del tejido cerebral se extrajo el cerebro y el cráneo; se normalizó de acuerdo con el volumen cerebral total, y a partir de este se segmentaron los volúmenes del núcleo caudado y del núcleo accumbens. Se utilizó el método de tractografía espacial estadística para la cuantificación y búsqueda de diferencias en el coeficiente de anisotropía fraccional. Resultados: El porcentaje de volumen de sustancia blanca respecto al volumen cerebral fue menor en los pacientes con VIH (42,83 ± 2,65%), comparado con los sujetos sanos (43,56 ± 1,60%). El porcentaje de volumen del núcleo de accumbens izquierdo en los pacientes con VIH fue del 0,0254 ± 0,0073 % del cerebro, y en los individuos sanos, del 0,0351 ± 0,0067% del cerebro; (p < 0,05). Conclusión: No fue evidente ni significativa la disminución del volumen del parénquima cerebral de la sustancia gris, a excepción del núcleo accumbens izquierdo. En relación con el volumen de la sustancia blanca, se hallaron cambios globales y no regionales en dichos tractos…


Cerebral atrophy is a common finding in patients infected with the Human Immuno-deficiency Virus (HIV), particularly in patients with dementia. This disease shows neocortical compromise in late stages as well as compromise in the basal ganglia in early or asyntomatic phases. Objective: Evaluate changes in total brain volume, caudate nucleus volume, nucleus accumbens volume, and fractional anisotropy of white matter tracts in HIV pa tients without neurodegenerative symptoms, in comparison with healthy subjects. Methods: For segmentation and quantification purposes of the brain tissue, the brain and skull were extracted and the tissue was normalized according to total brain volume. From the tissue thus obtained, the caudate nucleus and nucleus accumbens volumes were segmented. The method of statistic spatial tractography was used for quantification and search of differences in the fractional anisotropy coefficient. Results: The percentage of white mat ter volume with respect to brain volume was smaller in HIV patients (42.83±2.65 %) when compared with healthy subjects (43.56±1.60 %). The percentage of left nucleus accumbensvolume in HIV patients was 0.0254±0.0073 % of the brain and 0.0351±0.0067 % in healthy subjects; (p<0.05). Conclusions: It was not evident A decrease in the volume of the gray matter parenchyma was not evident or significant, except in the left nucleus accumbens. Global but not regional changes were found in white matter tracts…

ABSTRACT

Introducción. Para la obtención de imágenes con calidad diagnóstica en la población pediátrica por medio de la resonancia magnética es necesario usar la sedación profunda asistida por un anestesiólogo, dado que ésta garantiza la inmovilidad completa del paciente para el adecuado desarrollo del examen. Objetivo. Describir el uso de sedación profunda asistida por un anestesiólogo en los estudios de resonancia magnética para población pediátrica. Métodos. Estudio observacional de serie de casos; se eligieron aleatoriamente 113 exámenes de resonancia magnética asistida por anestesiólogo en pacientes menores de 15 años de edad, atendidos en la Fundación Instituto de Alta Tecnología Médica de Antioquia en el 2009; y para la concordancia entre observadores se evaluaron 84 exámenes con sus respectivas series de imágenes. Resultados. Los tiempos promedio de sedación de las resonancias magnéticas más comunes fueron: cráneo simple, 45,2 ± 12,4 minutos; cráneo contrastado, 46,3 ± 16,7 minutos; cardiaca, 96 ± 24,1 minutos; angio de cráneo, 60 ± 16,8 minutos, y cráneo-columna total, 76,3 ± 32 minutos. Al ajustar por sexo no se hallaron diferencias significativas (p > 0,05). Los medicamentos sedantes empleados para estos exámenes fueron: midazolam, ketamina, propofol, hidrato de cloral y fentanyl. Respecto a la fiabilidad de las series de imágenes de los pacientes con sedación profunda, se halló una excelente concordancia entre observadores (Kappa > 0,9). Conclusión. Se considera la sedación asistida por un anestesiólogo un procedimiento con baja tasa de complicaciones, el cual puede ser usado con mayor frecuencia en la población pediátrica para la obtención de imágenes con calidad diagnóstica en pacientes con comorbilidades y en procedimientos de resonancia magnética complejos.


Objetive. Obtaining diagnostic quality images in the pediatric population using magnetic resonance imaging, requires the use of deep sedation assisted by the anesthesiologist to ensure the totalimmobility of the patient for an adequate examination. Objective. To describe the use of deep sedation assisted by an anesthesiologist in magnetic resonance studies for the pediatric population. Methodos. Observational study of a series ofcases. 113 randomly selected MRI scans, with assisted sedation by an anesthesiologist in pediatric patients aged less than 15, treated at the Fundación Instituto de Alta Tecnología Médica de neAntioquia in 2009. The inter-observer consistency was evaluated in 84 examinations with their corresponding series of images.Results. Average sedation time for the most common MRIs were are follows: cerebral MRI, 45.2 ± 12.4 minutes; cerebral with contrast, 46.3 ± 16.7 minutes; cardiac, 96 ± 24.1 minutes; cerebral angiography, 60 ± 16.8 minutes and cerebral-total spine, 76.3 ± 32 minutes. No significant gender-adjusted differences were found (p > 0.05). The sedatives used for these examinations were: midazolam, ketamine, propofol, chloral hydrate and fentanyl. Excellent inter-observer consistency was found in terms of the reliability of the series of images of deep sedation patients (Kappa > 0.9).Conclusions. Sedation assisted by an anesthesiologist is considered a procedure with a low rate of complications that can be used more often in the pediatric population for obtaining diagnostic quality images in patients with co-morbidities and in complex MRI procedures.
