RESUMO
Background: Congenital diaphragmatic hernia (CDH) is associated with significant pulmonary morbidity. Previous investigation has shown that postnatal inpatient morbidity is linked to diaphragmatic defect size. The objective of this study was to evaluate long-term pulmonary outcomes by CDH study group defect size. Methods: A retrospective analysis was conducted for CDH patients (n=133) managed in a neonatal intensive care unit (NICU) at a single children's hospital within an adult hospital system and subsequently followed up at a comprehensive multidisciplinary CDH clinic (n=102) from January 2012 to April 2022. CDH patients were stratified according to Congenital Diaphragmatic Hernia Study Group (CDHSG) Stage, and then categorized as low-risk (LR), defect size A and B, or high-risk (HR), defect size C and D. Inpatient data, including the presence of pulmonary hypertension, extracorporeal life support (ECLS) utilization, and mechanical ventilation days, were collected. Post-discharge data including the prevalence of asthma, pulmonary hypertension, emergency department visits, the total number of hospitalizations, and average rehospitalization days were collected. Frequentist analysis was used. Results: The outcomes for 133 NICU patients were analyzed (HR: n=54, LR: n=79). During NICU stay, the prevalence of pulmonary hypertension [HR: 16/54 (30%) vs. LR: 9/79 (12%), P=0.009], ECLS utilization [HR: 19/54 (35%) vs. LR: 4/79 (5%), P<0.001], and the average number of mechanical ventilation days [HR: 17 days (IQR: 12-27) vs. LR: 5 days (IQR: 2-9), P<0.001] were significantly higher in the HR CDH group. Post NICU discharge, the prevalence of asthma [HR: 20/54 (37%), vs. LR: 17/79 (22%), P=0.050)] and the total days of rehospitalization [HR: 9 (IQR: 2-27) vs. LR: 4 (IQR: 1-8), P=0.035] were significantly higher in HR group. Of the patients seen in the comprehensive multidisciplinary CDH clinic, obstructive lung disease measured by impulse oscillometry was increased in the HR CDH population compared to the reference group [median R5Hz was 12.95 kPa/(L/s) in CDH vs. 9.8 kPa/(L/s) (P=0.010)]. Conclusions: HR CDHSG Stage is associated with worse inpatient and long-term pulmonary outcomes.
RESUMO
Severe acute respiratory syndrome coronavirus 2 has infected and caused the death of an alarming number of individuals worldwide. No specific treatment has been internationally standardized for coronavirus disease 2019 (COVID-19); however, in some cases, intravenous immunoglobulin (IVIG) has been used as adjuvant treatment in critically ill patients with COVID-19 pneumonia. We report a case of a 50-year-old man with severe COVID-19 pneumonia who received 5 days course of IVIG as adjuvant therapy. Invasive respiratory support was avoided. The patient had a successful recovery and was discharged without supplemental oxygen. A high dose of IVIG may improve survival in patients with severe COVID-19 pneumonia. In the current report, we reviewed literature on how IVIG use may improve the early stages of the disease.
RESUMO
BACKGROUND: Telemedicine is widely used but has uncertain value. We assessed telemedicine to further improve outcomes and reduce costs of comprehensive care (CC) for medically complex children. METHODS: We conducted a single-center randomized clinical trial comparing telemedicine with CC relative to CC alone for medically complex children in reducing care days outside the home (clinic, emergency department, or hospital; primary outcome), rate of children developing serious illnesses (causing death, ICU admission, or hospital stay >7 days), and health system costs. We used intent-to-treat Bayesian analyses with neutral prior assuming no benefit. All participants received CC, which included 24/7 phone access to primary care providers (PCPs), low patient-to-PCP ratio, and hospital consultation from PCPs. The telemedicine group also received remote audiovisual communication with the PCPs. RESULTS: Between August 22, 2018, and March 23, 2020, we randomly assigned 422 medically complex children (209 to CC with telemedicine and 213 to CC alone) before meeting predefined stopping rules. The probability of a reduction with CC with telemedicine versus CC alone was 99% for care days outside the home (12.94 vs 16.94 per child-year; Bayesian rate ratio, 0.80 [95% credible interval, 0.66-0.98]), 95% for rate of children with a serious illness (0.29 vs 0.62 per child-year; rate ratio, 0.68 [0.43-1.07]) and 91% for mean total health system costs (US$33 718 vs US$41 281 per child-year; Bayesian cost ratio, 0.85 [0.67-1.08]). CONCLUSION: The addition of telemedicine to CC likely reduced care days outside the home, serious illnesses, other adverse outcomes, and health care costs for medically complex children.
