Update in postinfectious bronchiolitis obliterans.

Postinfectious bronchiolitis obliterans (PiBO) is a rare and severe form of chronic obstructive lung disease caused by an infectious injury to the lower respiratory tract. The most commonly recognized inciting stimuli leading to PiBO are airway pathogens, such as adenovirus and Mycoplasma. PiBO is characterized by persistent and nonreversible airway obstruction, with functional and radiological evidence of small airway involvement.

Post-infectious bronchiolitis obliterans.

Bronchiolitis obliterans is a rare and severe chronic lung disease resulting from a lower respiratory tract lesion. It may occur after a bone marrow or lung transplantation, infectious diseases, or less frequently after inhaling toxic substances or after connective tissue diseases. Pathology, pathogenesis, and molecular biology, as well as the best treatment of bronchiolitis obliterans, remain the subject of ongoing research.

Pulmonary function of a paediatric cohort of patients with postinfectious bronchiolitis obliterans. A long term follow-up.

Background: Postinfectious bronchiolitis obliterans (BO) is a chronic respiratory disease that usually follows a severe adenovirus infection.

Objective: To determine the evolution of pulmonary function and clinical outcome of children with postinfectious BO during childhood.

Methods: The study included patients diagnosed with postinfectious BO in whom at least two spirometries were performed within a minimum interval of 3 months.

Clinical prediction rule to diagnose post-infectious bronchiolitis obliterans in children.

Rationale: Infant pulmonary function testing has a great value in the diagnosis of post-infectious bronchiolitis obliterans (BOs), because of characteristic patterns of severe and fixed airway obstruction. Unfortunately, infant pulmonary function testing is not available in most pediatric pulmonary centers.

Objective: To develop and validate a clinical prediction rule (BO-Score) to diagnose children under 2 years of age with BOs, using multiple objectively measured parameters readily available in most medical centers.

[Postinfectious bronchiolitis obliterans].

Bronchiolitis obliterans is an uncommon and severe form of chronic obstructive lung disease that results from an insult to the lower respiratory tract. The bronchiolitis obliterans was described as a complication of graft versus host disease in bone marrow or lung transplant recipients. Bronchiolitis obliterans is most commonly seen in children after severe viral lower respiratory tract infections.

Effects of inhaled fluticasone propionate in children less than 2 years old with recurrent wheezing.

Our objective was to evaluate the efficacy and safety of two doses of fluticasone propionate (FP) in young children with recurrent wheezing and risk factors for asthma. Our study design was a randomized, double-blind, placebo-controlled comparison of inhaled FP 50 mcg twice daily (FP 100) and 125 mcg twice daily (FP 250), for 6 months. Outcome measures included number of wheezing episodes, days on albuterol, height standard deviation score (height SDS), osteocalcin (OC), bone alkaline phosphatase fraction (AKP), insulin-like growth factor-binding protein 3 (IGFBP-3), and serum levels of cortisol (SC).

Acute viral bronchiolitis and its sequelae in developing countries.

Acute viral bronchiolitis (AVB) is a common disease found throughout the world. Various aspects of it are being studied: its epidemiology, diagnosis, prognosis and treatment. Most of these studies are being conducted in developed countries, with only a few taking place in developing countries.
