    Bedside clinical assessment predicts recurrence after hospitalization due to viral lower respiratory tract infection in young children
    (BMJ PUBLISHING GROUP, 2020) Arroyo, Maria; Salka, Kyle P.; Perez, Geovanny F.; Rodriguez Martinez, Carlos E.; Castro Rodriguez, Jose A.; Nino, Gustavo
    -Infants requiring hospitalization due to a viral lower respiratory tract infection (LRTI) have a high risk of developing recurrent respiratory illnesses in early life and asthma beyond childhood. Notably, all validated clinical scales for viral LRTI have focused on predicting acute severity instead of recurrence. We present a novel clinical approach combining individual risk factors with bedside clinical parameters to predict recurrence after viral LRTI hospitalization in young children. A retrospective longitudinal cohort of young children (<= 3 years) designed to define clinical predictive factors of recurrent respiratory illnesses within 12 months after hospitalization due to PCR-confirmed viral LRTI. Data collection was through electronic medical record. We included 138 children hospitalized with viral LRTI. Using automatic stepwise logistic model selection, we found that the strongest predictors of recurrence in infants hospitalized for the first time were severe prematurity (<= 32 weeks' gestational age, OR=5.19; 95% CI 1.76 to 15.32; p=0.002) and a clinical score that weighted hypoxemia, subcostal retractions and wheezing (OR=3.33; 95% CI 1.59 to 6.98; p<0.001). After the first hospitalization, the strongest predictors of subsequent episodes were wheezing (OR=5.62; 95% CI 1.03 to 30.62; p=0.04) and family history of asthma (OR=5.39; 95% CI 1.04 to 27.96; p=0.04). We found that integrating individual risk factors (eg, prematurity or family history of asthma) with bedside clinical assessment (eg, wheezing, subcostal retractions or hypoxemia) can predict the risk of recurrence after viral LRTI hospitalization in infants. This strategy may enable clinically oriented subsetting of infants with viral LRTI based on individual predictors for recurrent respiratory illnesses during early life.

    Diagnostic and treatment approach of chronic cough in childhood
    (SOC ARGENTINA PEDIATRIA, 2013) Saranz, Ricardo J.; Lozano, Alejandro; Lozano, Natalia A.; Castro Rodriguez, Jose A.
    Chronic cough is a symptom of various respiratory and non-respiratory conditions with negative impact on quality of life of children and their families. The pediatricians should focus their efforts in search for etiological diagnosis. A careful medical history and physical examination are the mainstays of diagnosis and guidance to further studies that may contribute to detection of final causes.

    Effectiveness of Asthma Education with and Without a Self-Management Plan in Hospitalized Children
    (TAYLOR & FRANCIS LTD, 2009) Espinoza Palma, Tatiana; Zamorano, Alejandra; Arancibia, Francisca; Bustos, Maria Francisca; Jose Silva, Maria; Cardenas, Consuelo; De La Barra, Pedro; Puente, Victoria; Cerda, Jaime; Castro Rodriguez, Jose A.; Prado, Francisco
    Background. Formal education in primary care can reduce asthma exacerbations. However, there are few studies in hospitalized children, with none originating in Latin America. Methods. A prospective randomized study was designed to evaluate whether a full education with self-management plan (ESM) was more effective than an education without self-management plan (E) in reducing asthma hospitalization. Children (5 to 15 years of age) who were hospitalized for an asthma attack were divided in two groups. Children in the E group received general instructions based on a booklet. Those in the ESM group received the same booklet plus a self-management guide and a puzzle game that reinforces the lessons learned in the booklet. Patients were interviewed every 3 months, by telephone, for one year. Interviewers recording the number of hospitalizations, exacerbations, and emergency visits for asthma and oral steroid burst uses. Results. From 88 children who met the inclusion criteria, 77 (86%) completed one year of follow-up (41 from E and 36 from ESM group). Overall, after one year, the hospitalization decreased by 66% and the inhaled corticosteroids therapy increased from 36% to 79%. At the end of the study, there was no difference in exacerbations, emergency visits, oral steroid burst uses, or hospitalizations between the two groups. Conclusions. Asthma education with or without a self-management plan during asthma hospitalization were effective in reducing exacerbations, emergency visits, oral steroid burst uses, and future rehospitalizations. This evidence supports the importance of providing a complete asthma education plan in any patient who is admitted for asthma exacerbation.

    The asthma predictive index as a surrogate diagnostic tool in preschoolers: Analysis of a longitudinal birth cohort
    (WILEY, 2021) Castro Rodriguez, Jose A.; Forno, Erick; Padilla, Oslando; Casanello, Paola; Krause, Bernardo J.; Borzutzky Schachter, Arturo
    Diagnosing asthma in preschool children remains an unsolved challenge, at a time when early identification would allow for better education and treatment to prevent morbidity and lung function deterioration. Objective To evaluate if the asthma predictive index (API) can be used as surrogate for asthma diagnosis in preschoolers. Methods Birth cohort of 339 pregnant women enrolled at delivery and their offspring, who were followed for atopy, wheezing, and other respiratory illnesses through 30 months of age. The API was determined at 30 months of age by the researchers; and examined its association with physician-diagnosed asthma during the first 30 months, made independently by the primary care physician not involved in the study. Results Among 307 offspring with complete follow-up, 44 (14.3%) were API+. Maternal body mass index, maternal education, past oral contraceptive use, birthweight, placenta weight, age of daycare at 12 m, gastroesophageal reflux disease at 12 m, acute otitis media at 18 m, bronchiolitis, croup and pneumonia, cord blood adiponectin were all associated with API+. In the multivariable analysis, API+ was associated with almost sixfold odds of asthma diagnosis (adjusted OR = 5.7, 95% CI [2.6-12.3]), after adjusting for the relevant covariates above including respiratory infections like bronchiolitis and pneumonia. The API sensitivity was 48%, specificity 92%, 61% PPV, 88% NPV, 6.4 LR+, 0.56 LR-, 0.84 diagnosis accuracy. The adjusted odds for asthma was 11.4. Conclusions This longitudinal birth cohort suggests, for first time, that API (a structured definition for asthma), could be used as a diagnostic tool, not only as a prognostic tool, in toddlers and preschoolers.
