BACKGROUND AND OBJECTIVE

Pediatric post-operative congenital diaphragmatic hernia (CDH) patients have been shown to encounter reduced pulmonary function tests (PFT) potentially leading to respiratory symptoms. Strategies involving exercise have been used to improve PFT. This meta-analysis aims to determine the effectiveness of exercise in improving lung function in pediatric post-operative CDH patients.

An electronic search was done on May 2023 in MEDLINE via Pubmed, Cochrane Library, Embase, ClinicalKey, Scopus, Google Scholar, and Herdin Plus, using the search terms "exercise" and "congenital diaphragmatic hernia" and "children" or "pediatric" and "pulmonary function" or "lung function". The study included pediatric patients in whom CDH has been surgically corrected, and excluded patients who were unable to perform the test maneuvers, have cardiopulmonary instability, and have serious associated anomalies. Randomized controlled trials (RCT) were identified and independently assessed by two review authors. Each RCT was independently assessed for bias by two review authors using the Cochrane Handbook for Systematic Reviews of Interventions. The RevMan 5.4 software was used for statistical analysis.

A total of 124 participants from three studies were included in the meta-analysis. The pooled mean difference showed a significantly higher mean functional vital capacity (FVC) (MD=6.12, 95%CI=3.91 to 8.33, p-value < 0.00001) and forced expiratory volume in 1 second (FEV1 ) (MD=6.25, 95%CI=3.39 to 9.10, p-value < 0.0001) in the study group compared to the control group.

Exercise may be effective in improving lung function in children with pediatric post-operative CDH. However, the study is limited by its small sample size, the lack of assessment of long-term outcomes, and the difference in exercise regimens used in each RCT. Further studies are recommended to determine the most optimal exercise regimen and to measure its effect on the other outcomes for this population.

Objective: Our study aimed to identify and describe pulmonary complications and its associated risk factors in children with suspected or confirmed obstructive sleep apnea (OSA) who underwent tonsillectomy or adenotonsillectomy in a tertiary government hospital. Methods: We conducted a retrospective cohort study. Medical charts of pediatric patients with suspected or confirmed OSA who were admitted for tonsillectomy or adenotonsillectomy from January 1, 2016 to December 31, 2020 were retrieved and reviewed. Information of the individual patients including the demographic data, clinical profile, polysomnography results, and presence of postoperative pulmonary complications were recorded. Descriptive statistics was utilized to present continuous data while frequency and percentage for categorical data. Fisher exact test was used to compare the demographic profile of patients with postoperative pulmonary complications from those without. Results: A total of 90 patient records were analyzed. The mean age of the patient population was 7.87 years, 55.6% were male, 17.8% of patients were classified as obese. Thirty-four children had preoperative polysomnography and of these, 47.1% were classified as severe. Only two (2.2%) patients had postoperative pulmonary complications, which were bronchospasm and desaturation, respectively. There were no statistically significant differences noted in comparing the clinicodemographic profile of patients with postoperative pulmonary complications from those without complications. Conclusion Our results showed that most pediatric patients with suspected or confirmed OSA who underwent adenotonsillectomy did not have pulmonary complications.

OBJECTIVE

Our study aimed to determine the clinical profile and pulmonary function of pediatric patients with Duchenne Muscular Dystrophy (DMD). We also characterized the stages of progression of the disease and determined their potential association with spirometry variables.

In this cross-sectional study, we used data obtained from a review of medical records of all pediatric patients (0-18 years old) with DMD seen in a multidisciplinary neuromuscular clinic of a tertiary government hospital from August 2018 until March 2020.

Included were 30 patients subdivided into groups according to the stage of disease progression. Overweight (26.7%), obesity (20%), and scoliosis (26.7%) were common among non-ambulatory patients. Only one late ambulatory patient had evidence of ineffective airway clearance. Symptoms of sleep-disordered breathing, particularly snoring (66.7%) and apnea (6.7%), were common across all disease stages. All patients had normal peripheral oxygen saturation on room air. The mean peak expiratory flow rate was 215.6 (±84) L/min. The mean Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), and FEV1/FVC were 66.2% (±23.7), 67.7% (±23.8), and 97.5 (±3.2), respectively. Among patients with polysomnography results, the average apnea-hypopnea index (AHI) per hour was 3 (±1.6). When patients were compared according to their stage disease progression, however, no significant differences exist.

This is the first study on the pulmonary function of Filipino pediatric patients with DMD. Spirometry patterns characteristic of restrictive lung disease were observed. Prospective studies may help identify respiratory variables that significantly correlate with pulmonary function.

Objective: This paper aims to determine the respiratory manifestations, radiologic findings, and management of coronavirus-19 (COVID-19) among the hospitalized children of different age groups based on a systematic review of literature.

Methodology: We searched the MEDLINE, Google Scholar, Cochrane, and MedRvrix databases for relevant studies on pediatric COVID-19 done between January 1 to May 25, 2020. Data on demographic features, pulmonary symptoms, chest imaging findings, and oxygen support were extracted in a data abstraction form and analyzed among the different pediatric age groups.

Results:?Sixteen studies were included in this systematic review, with a total of 61 patients. Thirty-nine patients (64%) belong to the 2 to 12 year age group. Cough was the most commonly reported respiratory symptoms among children older than one month. Most of the patients, particularly adolescents, had asymptomatic or mild infection. On chest imaging, infiltrates and ground-glass opacities were the most common abnormalities. Oxygen supplementation via nasal cannula, non-invasive ventilation, and mechanical ventilation was noted in three cases.

Conclusion: Our systematic review shows that COVID-19 can present with a spectrum of respiratory manifestations and disease severity as well as a variety of radiologic abnormalities across different pediatric age groups. Whilemost children do not develop hypoxemia warranting oxygen supplementation, a severe respiratory infection can still manifest in children. Asymptomatic and milder infections are common and highlight the need for appropriate respiratory precautions. More pediatric studies on the pulmonary manifestations and management of children with COVID-19 can aid in a better understanding of this novel disease.

Background. Coronavirus Disease 2019 (COVID-19) presents with respiratory signs and symptoms in children. Presently, there are no local studies on the pulmonary manifestations and management of COVID-19 among children. Objective. Our study aimed to identify and describe the presenting respiratory signs and symptoms, oxygenation status, radiologic findings, blood gas analysis, and pulmonary interventions among children admitted for COVID-19. We also analyzed the clinical and radiologic variables associated with mortality. Methodology. This is a retrospective study using data obtained from a review of medical records from April 1, 2020, to June 30, 2020, at a tertiary government institution in the Philippines. All pediatric patients (0-18 years) hospitalized for probable or confirmed COVID-19 during the said time period were included in this study. Univariate and multivariate logistic regression was applied to determine factors affecting mortality. Results. A total of 25 pediatric patients with a mean age of 7 years old (age range: 11 days to 18 years) were admitted for COVID-19. Cough (44%) and dyspnea (24%) were the most common presenting respiratory symptoms, while tachypnea (68%), crackles (36%), and peripheral oxygen desaturation (36%) were the most common respiratory signs. Indeterminate findings for COVID-19 such as multifocal or diffuse ground-glass opacities and/or consolidations were the most common radiographic abnormalities. Invasive ventilatory support was administered to 6 cases of severe COVID-19 and 4 critical cases. There were no variables that correlated significantly with mortality. Conclusion. Respiratory signs and symptoms were prominent in our cohort of children admitted due to COVID-19. Mechanical ventilation was required in more severe cases. Larger prospective studies may help identify variables that significantly correlate with poor outcomes among children with COVID-19.
