DISCUSIÓN: se deben realizar acciones que mejoren la calidad de atención y satisfacción del paciente, una de ellas es disminuir los periodos de espera en las programaciones de ecografía.
INTRODUCTION: social security provides medical care for salaried workers. OBJECTIVES: to determine waiting times for scheduled ultrasound appointments and the level of satisfaction of insured patients at Policonsultorio 20 octubre, Caja Petrolera the Salud. METHODS: this is a descriptive, cross sectional, quantitative study. One thousand one hundred and ten ultrasounds orders from the 2012 2014 administration and 1110 patients who had ultrasounds orders currently scheduled were selected for review. Clinical records and ultrasounds files were reviewed and patients answers using a standardized questionnaire using the Likert scale were used to measure their level of satisfaction. RESULTS: twenty-six percent of the patients waited 4.1 to 5.1 weeks (29-35 days), there were 2.2 ultrasounds orders per patient, 93% of the patients are somewhat or completely dissatisfied with the waiting times, and 58% consider it acceptable to wait from 1.1 to 2.0 weeks (2-14 days) to undergo the study. DISCUSSION: Actions are needed to improve the quality of care and patient satisfaction, one of which is to shorten waiting times for scheduled ultrasound.

UNLABELLED: Respiratory syncytial virus (RSV) infection has been associated to recurrent wheezing, but pathogenic mechanisms are unclear. Interleukin-4/Interleukin-13 (IL-4/IL-13) pathway is involved in both conditions. A common host genetic susceptibility may exist in patients whom RSV will trigger severe illness and those who develop recurrent wheezing. OBJECTIVE: To assess, by a candidate-gene approach, whether genetic polymorphisms in IL-4/IL-13 pathway are associated with RSV infection severity and its outcome in Chilean children. A cohort of 118 RSV-infected infants was analyzed and followed for one year. Severity of acute infection and later recurrent wheezing were characterized. Alleles and genotypes frequencies were determined for two SNP in each of the genes IL-4, IL-13 and IL-4Rα. Association tests and interaction analyses were performed. Enrollment included 60 moderate and 58 severe cases. Two SNP were found associated to severity during acute infection in IL-4Rα gene (Gln551Arg, Ile50Val). The follow up was completed in 71% of patients (84/118). Later recurrent wheezing was 54% in severe group, versus 31% in moderate cases (p=0.035). In relation to outcome, allele Ile50 in IL-4Rα was more frequent in patients with moderate disease and no wheezing outcome. A common protector genotype is proposed for Chilean children: IL-4Rα Ile/Ile. CONCLUSION: Genetic variations in the host are associated to infection severity and outcome. A common genetic background might be influencing both pathologies.

BACKGROUND: Respiratory syncytial virus (RSV) is a major cause of acute lower respiratory infection in infants. The immune response plays a leading role in the severity of the disease. We hypothesized that severe RSV disease is associated with an impaired immune response characterized by low circulating T lymphocytes and plasma cytokine concentrations. METHODS: We evaluate the in vivo immune responses of previously healthy infants with their first proven RSV-acute lower respiratory infection that required hospitalization. According to the clinical severity, defined by using a strict scoring system, the in vivo immune response was compared through the analysis of plasma cytokine values and the phenotyping of peripheral blood lymphocyte and natural killer (NK) cells. RESULTS: Absolute blood cell counts of CD4+, CD8+, and CD19+ lymphocytes and NK cells were lower in subjects with RSV than in control infants. Lowest cell counts were observed in more severe RSV-infected infants. Significant low values were obtained in CD8+ lymphocytes (P = 0.03) and nonactive NK cells, that express CD94 antigen (P = 0.046). In contrast, activated NK cells that do not express CD94 molecules were significantly higher in RSV infected infants than in healthy controls (% of cells: P = 0.004). The interferon-gamma and tumor necrosis factor-alpha values in RSV infected patients were lower than in controls subjects. Interleukin-17 cytokine was not detected in healthy infants and the largest concentration was found in moderately ill patients as compared with severe cases (P = 0.033). RSV infection showed significantly higher interleukin-8 chemokine than in control infants (P = 0.024). CONCLUSION: We propose that severe RSV infection in very young infants is associated with poor blood proinflammatory cytokine production, low counts of CD8+ T cells and with a greater activity of a group of NK cells, that are independent of the major histocompatibility complex class Ib recognition system.

RESUMO
El anticoagulante lúpico es un inhibidor de la coagulación sanguínea adquirido espontáneamente que interfiere con la activación de la protrombina por el complejo activador. Este inhibidor, una inmunoglobulina, aparece más comúnmente en el plasma de pacientes con desórdenes autoinmunes incluyendo el lupus eritematoso sistémico, pero también ha sido asociado con enfermedades no relacionadas directamente con el sistema inmune y en pacientes sin ninguna enfermedad demostrable. Los pacientes con este "anticoagulante" usulamente están libres de sangrado a pesar de las anormalidades en su coagulación. Paradójicamente, han sido reportados episodios de trombosis venosa profunda, trombosis arterial u oclusión cerebrovascular, embolismo pulmonar y trombosis en la circulación renal. El mecanismo de estas asociaciones es desconocido, pero su comprensión será necesaria para un mejor diagnóstico y tratamiento de esta nueva entidad
