RESUMO
Background: Echinococcosis is a uncommon condition in pediatric patients, and encompasses alveolar and cystic forms, predominantly affecting the lungs and liver. Transmission occurs primarily through zoonotic means, such as the contamination of water and food by infected dog and other canid feces. Diagnosis can be challenging due to nonspecific symptoms that often mimic pneumonia. The case: A 6-year-old female patient from a rural area in Ecuador who initially presented with nonspecific symptoms indicative of pneumonia. However, further investigation into socio-environmental factors led to a diagnosis of pulmonary and hepatic hydatid disease. Conclusion: The timely and accurate diagnosis of this infectious disease enabled the patient to receive appropriate treatment and surgical intervention, leading to her complete recovery.
RESUMO
BACKGROUND: Idiopathic hypereosinophilic syndrome (IHES) is a disorder characterized by abnormal and persistent peripheral blood hypereosinophilia (eosinophil count ≥ 1.5 × 109/L and ≥10% eosinophils) with duration ≥ 6 months, associated organ damage, and/or dysfunction attributable to tissue eosinophilic infiltrate of unknown cause. IHES affects different organs such as the heart, lungs, nervous system, and skin, with renal involvement being rare in this condition. CASE PRESENTATION: We present a case of a young patient with IHES and immune complex-mediated membranoproliferative glomerulonephritis with nephrotic syndrome, as a rare renal manifestation. We discuss the clinical, analytical, and histopathologic renal and hematologic features, comparing them with other reported cases in the literature.
RESUMO
Objetivos: Determinar los factores asociados al desarrollo de infecciones del tracto urinario causadas por Escherichia coli productora de betalactamasas de espectro extendido (BLEE). Material y métodos: Estudio caso y control, realizado en el Hospital Cayetano Heredia. Se incluyeron 150 casos y 150 controles, definiéndose como caso al paciente con urocultivo positivo para E. coli BLEE y como control al paciente con urocultivo positivo para E. coli no BLEE. Se realizó un análisis bivariado y regresión logística binaria para aquellos factores que resultaron significativos en el análisis bivariado. Resultados: Después de la regresión logística binaria, los factores asociados a la presentación de infecciones urinarias por E. coli BLEE encontrados en el estudio fueron sexo masculino (OR 5,13 - IC 95% 2,37 - 11,07), edad mayor a 45 años (OR 2,65 - IC 95% 1,61 - 4,38) y hospitalización previa (OR 2,57 - IC 95% 1,39-4,75). Conclusiones: Los pacientes varones, mayores de 45 años y con antecedente de hospitalización en el último año estuvieron más propensos a presentar infecciones urinarias por E. coli BLEE, lo cual se debe tomar en cuenta para el manejo empírico de esta clase de pacientes.

Objectives: To determine factors associated with urinary tract infections caused by extended spectrum betalactamase producing strains (ESBL) of Escherichia coli. Methods: Case-control study performed at Hospital Cayetano Heredia; 150 cases (patients with positive urine cultures for an ESBL producing strain of E. coli) and 150 controls (patients with positive urine culture to a non-ESBL producing strain of E. coli) were included. Bivariate and multivariate logistic regression analysis were performed. Results: Factors associated with having an infection by an ESBL producing strain of E. coli in the multivariate analysis were male sex (OR 5.13 - CI 95% 2.37 - 11.07), age above 45 years (OR 2.65 - CI 95% 1.61 - 4.38) and previous hospitalization (OR 2.57 - CI 95% 1.39-4.75). Conclusions: Empirical treatment for ESBL producing strains of E. coli should be targeted to male patients older than 45 years of age, and in those with a previous hospitalization. (AU)
