Treatment, outcomes and costs of asthma exacerbations in Chilean children: a prospective multicenter observational study

Objective: To describe potential regional variations in therapies for severe asthma exacerbations in Chilean children and estimate the associated health expenditures. Methods: Observational prospective cohort study in 14 hospitals over a one-year period. Children five years of age or older were eligible for inclusion. Days with oxygen supply and pharmacological treatments received were recorded from the clinical chart. A basic asthma hospitalization basket was defined in order to estimate the average hospitalization cost for a single patient. Six months after discharge, new visits to the Emergency Room (ER), use of systemic corticosteroids and adherence to the controller treatment were evaluated. Results: 396 patients were enrolled. Patients from the public health system and from the north zone received significantly more days of oxygen, systemic corticosteroids and antibiotics. Great heterogeneity in antibiotic use among the participating hospitals was found, from 0 to 92.3% (ICC 0.34, 95% CI 0.16-0.52). The use of aminophylline, magnesium sulfate and ketamine varied from 0 to 36.4% between the different Pediatric Intensive Care Units (ICC 0.353, 95% CI 0.010-0.608). The average cost per inpatient was of $1910 USD. 290 patients (73.2%) completed the follow-up six months after discharge. 76 patients (26.2%) were not receiving any controller treatment and nearly a fourth had new ER visits and use of systemic corticosteroids due to new asthma exacerbations. Conclusions: Considerable practice variation in asthma exacerbations treatment was found among the participating hospitals, highlighting the poor outcome of many patients after hospital discharge, with an important health cost

Hospitalizations for asthma exacerbation in Chilean children: A multicenter observational study

BACKGROUND: Asthma hospitalization rates in Chilean children have increased in the last 14 years, but little is known about the factors associated with this. OBJECTIVE: Describe clinical characteristics of children hospitalized for asthma exacerbation. METHODS: Observational prospective cohort study in 14 hospitals. Over a one-year period, children five years of age or older hospitalized with asthma exacerbation were eligible for inclusion. Parents completed an online questionnaire with questions on demographic information, about asthma, indoor environmental contaminant exposure, comorbidities and beliefs about disease and treatment. Disease control was assessed by the Asthma Control Test. Inhalation technique was observed using a checklist. RESULTS: 396 patients were enrolled. 168 children did not have an established diagnosis of asthma. Only 188 used at least one controller treatment at the time of hospitalization. 208 parents said they believed their child had asthma only when they had an exacerbation and 97 correctly identified inhaled corticosteroids as anti-inflammatory treatment. 342 patients used the wrong spacer and 73 correctly performed all steps of the checklist. CONCLUSIONS: Almost half of the patients were not diagnosed with asthma at the time of hospitalization despite having a medical history suggestive of the disease. In the remaining patients with an established diagnosis of asthma potentially modifiable factors like bad adherence to treatment and poor inhalation technique were found. Implementing a nationwide asthma program including continued medical education for the correct diagnosis and follow up of these patients and asthma education for patients and caregivers is needed to reduce asthma hospitalization rates in Chilean children

Sialorrea neurogénica infantil y el manejo con la toxina botulínica: revisión de la literatura y reporte del caso de un niño con traqueostomía y ventilación mecánica crónica / Neurogenic drooling child and his treatment with botulinum toxin: a review of the literature and case report of a child with chronic tracheostomy and mechanical ventilation

Drooling is defined as non-intentional salivary loss from mouth. Its presence may lead to functional, psychological and social impairments, which affect patients and caregivers as well. Anterior drooling, where salivary flow escapes from mouth to outside, affects social relations, constituting a physical contact barrier and having a negative impact on quality of life, and it also interfere on speech and communication. Posterior drooling, where salivary flow goes towards the throat is associated to severe swallowing disorders, being an important aspiration risk. Although drooling etiology is multifactorial, it’s often seen associated to a neuromuscular dysfunction. The approach to drooling should be made by a multidisciplinary team. Therapeutic approach could be non-pharmacologic, pharmacologic, systemic or local. Ultrasound guidance Botulinum toxin injection is an efficient and safe alternative. A 4-year-old male with posterior fossa astrocytoma, VI-XI CN impairment, prolonged mechanical ventilation and tracheostomy, swallowing disorder and hypersalivation is presented. Drooling management with botulinum toxin A injection in both parotid and submandibular glands under ultrasound guidance was performed, with an important salivary flow decrease, which allowed him to open his mouth without saliva loss, having a positive impact on communication and socialization, improving his quality of life as well.

La sialorrea se define como la pérdida no intencional de saliva desde la boca. Su presencia puede conducir a alteraciones funcionales, psicológicas y sociales, que afectan tanto al paciente como a sus cuidadores. La sialorrea anterior, donde la saliva es derramada desde la boca al exterior afecta la socialización, constituyéndose como una barrera para el contacto físico e impacta en forma negativa sobre la calidad de vida, además interfiere en el lenguaje, el habla y la comunicación. La sialorrea posterior que es derramada hacia del itsmo de las fauces, se asocia a trastornos severos de la deglución, constituyendo un riesgo importante de aspiración. Aún cuando la etiología de la sialorrea es multifactorial, frecuentemente la vemos asociada a una disfunción neuromuscular. Su abordaje debe ser realizado por un equipo multidisciplinario. El enfoque terapéutico puede ser, no farmacológico o farmacológico, sistémico o local. Una de las alternativas es la infiltración con toxina botulínica guiada en forma ecográfica que ha demostrado ser eficiente y segura. Se presenta el caso de un preescolar de 4 años con antecedente de astrocitoma de fosa posterior, compromiso de VI al XI pares craneanos, ventilación mecánica prolongada a través de traqueostomía, trastorno de deglución e hipersalivación secundaria. Se realiza el manejo de la sialorrea con toxina botulínica A en parótidas y glándulas submandibulares con marcación ecográfica, resultando una disminución importante del flujo de saliva que le permite abrir la boca sin escurrimiento. Lo anterior impacta positivamente en la comunicación y socialización, además de mejorar su calidad de vida.

Blood host sources of Mepraia spinolai (Heteroptera: Reduviidae), wild vector of chagas disease in Chile.

There are two vectors of the Chagas' disease in Chile: Triatoma infestans Klug the domestic vector and Mepraia spinolai Porter the sylvatic vector. The alimentary profile of M. spinolai has been poorly studied. In this work we study the participation of humans, goats, dogs, cats, rodents, rabbits, birds (hens) and reptiles in the diet of M. spinolai by analyzing the intestinal content through immunoradiometric assay. To put our results in a general context, we also compared the diet with that described for T. infestans. In decreasing order, we detected blood of rabbits, dogs, goats, rodents, humans, and birds (hens). There were 12.3% of insects infected with T. cruzi, but this fact was not significant for diet variance. In warm weather there was a larger diversity of alimentary sources than in a cold one. The niche breadth increased from 0.029 in cold weather to 0.464 in warm weather. The niche overlap of T. infestans and M. spinolai was 0.23.

[Maternal connective tissue disease associated with congenital AV block]. / Enfermedad del tejido conectivo materna asociada a bloqueo av congenito.

We report 3 patients with congenital A-V block whose mothers had anti-Ro or anti-La antibodies. One of them had systemic lupus with serum anti-Ro antibodies; the other had anti-Ro antibodies and no clinical manifestations; the third had an undifferentiated connective tissue disorder with anti-La antibodies in the serum. The epidemiology of this association is discussed as well as some therapeutic options.
