Congenital Lung Agenesis: Incidence and Outcome in the North of England

BACKGROUND

Unilateral lung agenesis is an uncommon congenital abnormality, with a lack of reported accurate incidence estimates. Prognosis is also uncertain, with older literature reporting poor outcomes.

METHODS

The North of England register of congenital anomalies (Northern Congenital Abnormality Survey) records cases of congenital anomalies to mothers' resident in the region. We used the register to identify all patients with congenital lung agenesis born between 2004 and 2013 to calculate an accurate incidence estimate and report clinical outcomes with contemporary management.

RESULTS

Four patients with congenital lung agenesis were born during the study period, giving an estimated incidence in the North of England of 1.22 per 100,000 live births (95% confidence interval, 0.33-3.11). Two patients had associated congenital heart disease requiring corrective surgery, and one had musculoskeletal anomalies. All four patients are alive and well without a regular oxygen requirement.

CONCLUSION

Contrary to previous reports, the medium term outcomes in our patients have been good, even when lung agenesis is associated with other congenital anomalies. Long-term prognosis with modern management remains unknown, and the potential for the development of pulmonary hypertension remains a concern.

Recommendations for long-term home oxygen therapy in children and adolescents

OBJECTIVE

To advise pediatricians, neonatologists, pulmonologists, pediatric pulmonologists, and other professionals in the area on the main indications and characteristics of long-term home oxygen therapy in children and adolescents.

DATA SOURCE

A literature search was carried out in the MEDLINE/PubMed database (1990 to 2011). Additionally, references from selected studies were included. As consistent scientific evidence does not exist for many aspects, some of the recommendations were based on clinical experience.

DATA SYNTHESIS

Long-term home oxygen therapy has been a growing practice in pediatric patients and is indicated in bronchopulmonary dysplasia, cystic fibrosis, bronchiolitis obliterans, interstitial lung diseases, and pulmonary hypertension, among others. The benefits are: decrease in hospitalizations, optimization of physical growth and neurological development, improvement of exercise tolerance and quality of sleep, and prevention of pulmonary hypertension/cor pulmonale. The levels of oxygen saturation indicative for oxygen therapy differ from those established for adults with chronic obstructive pulmonary disease, and vary according to age and disease. Pulse oximetry is used to evaluate oxygen saturation; arterial blood gas is unnecessary. There are three available sources of oxygen: gas cylinders, liquid oxygen, and oxygen concentrators. The flows used are usually smaller, as are the number of hours/day needed when compared to the use in adults. Some diseases show improvement and oxygen therapy discontinuation is possible.

CONCLUSIONS

Long-term home oxygen therapy is increasingly common in pediatrics and has many indications. There are relevant particularities when compared to its use in adults, regarding indications, directions for use, and monitoring.

Impact of home oxygen therapy on hospital stay for infants with acute bronchiolitis

Acute bronchiolitis has been associated with an increasing hospitalization rate over the past decades. The aim of this paper was to estimate the impact of home oxygen therapy (HOT) on hospital stay for infants with acute bronchiolitis. A retrospective cohort study was done including all children aged ≤ 12 months discharged from a pediatric tertiary-care center with a diagnosis of bronchiolitis, between November 2007 and March 2008. Oxygen was administered according to a standardized protocol. We assumed children with the following criteria could have been sent home with O(2), instead of being kept in hospital: age ≥ 2 months, distance between home and hospital <50 km, in-hospital observation ≥ 24 h, O(2) requirement ≤ 1.0 L/min, stable clinical condition, no enteral tube feeding, and intravenous fluids <50 mL/kg/day. Children with significant underlying disease were excluded. A total of 177 children were included. Median age was 2.0 months (range 0-11), and median length of stay was 3.0 days (range 0-18). Forty-eight percent of patients (85/177) received oxygen during their hospital stay. Criteria for discharge with HOT were met in 7.1 % of patients, a mean of 1.8 days (SD 1.8) prior to real discharge. The number of patient-days of hospitalization which would have been saved had HOT been available was 21, representing 3.0 % of total patient-days of hospitalization for bronchiolitis over the study period (21/701).

CONCLUSIONS

In this study setting, few children were eligible for an early discharge with HOT. Home oxygen therapy would not significantly decrease the overall burden of hospitalization for bronchiolitis.

Programa de oxigenoterapia domiciliar para crianças egressas de uma unidade neonatal: relato da experiência de dez anos

OBJETIVO: Descrever os resultados do programa de oxigenoterapia domiciliar, com uso de concentrador de oxigênio, utilizado por crianças egressas de uma unidade neonatal ao longo de seus primeiros dez anos. MÉTODOS: Estudo de corte transversal com componente analítico para avaliar o programa de oxigenoterapia domiciliar de uma unidade neonatal de um hospital público universitário do interior do Estado de São Paulo durante o período de novembro de 1996 a dezembro de 2006. RESULTADOS: Foram identificadas 160 crianças com indicação de oxigenoterapia domiciliar, das quais 63,3% apresentavam displasia broncopulmonar. Em média, 3,0% de todos os pacientes internados e 8,6% dos recém-nascidos com peso inferior a 1500g ao nascer receberam alta em oxigenoterapia. A duração média do uso de O2 no domicílio foi de 42,3±54,0 dias. Na comparação das características demográficas da população e do tempo de uso de O2 domiciliar, não se observaram diferenças significativas entre os anos. Não houve correlação entre o tempo de ventilação mecânica e a duração da terapia domiciliar. Houve necessidade de cuidados especiais, além do uso de O2 e medicações, em 22,3% dos casos. Nos primeiros dois anos de vida, a taxa de morbidade e de mortalidade foram, respectivamente, 40,1 e 14,1%. CONCLUSÕES: O uso de oxigênio domiciliar, com sistema de concentrador de oxigênio, é uma alternativa terapêutica factível em nosso meio, merecendo mais atenção dos profissionais de saúde e maior investimento das instituições de saúde. São necessários mais estudos nacionais para se aprimorar a qualidade do atendimento e a segurança destes programas para a população neonatal.

Pulmonary hypertension in infants with bronchopulmonary dysplasia

An increase in the number of preterm infants and a decrease in the gestational age at birth have resulted in an increase in the number of patients with significant bronchopulmonary dysplasia (BPD) and secondary pulmonary hypertension (PH). PH contributes significantly to the high morbidity and mortality in the BPD patients. Therefore, regular monitoring for PH by using echocardiography and B-type natriuretic peptide (BNP) or N-terminal-proBNP must be conducted in the BPD patients with greater than moderate degree to prevent PH and to ensure early treatment if PH is present. In the BPD patients with significant PH, multi-modality treatment, including treatment for correcting an underlying disease, oxygen supply, use of diverse selective pulmonary vasodilators (inhaled nitric oxide, inhaled prostacyclins, sildenafil, and endothelin-receptor antagonist) and other methods, is mandatory.
