ABSTRACT
Introduction Infants in the neonatal intensive care unit (NICU) are vulnerable to ventilator-associated pneumonia (VAP), which increases their morbidity and mortality. There is a significant overlap of clinical features of neonatal VAP with other pulmonary pathologies, particularly in preterm infants, which can make the definitive diagnosis and management of VAP challenging. Objective Our study surveyed NICU providers across the United States to understand the perspectives and variations in neonatal VAP diagnostic and management practices. Methods The REDCap survey was distributed to the actively practicing members of the Section on Neonatal-Perinatal Medicine (SoNPM) of the American Academy of Pediatrics (AAP). We used descriptive statistics to analyze the data from the respondents. Results Of 254 respondents, the majority (86.6%, 220) were neonatologists and had a relatively even geographical distribution. Most (75.9%, 193) stated that they would perform a gram stain and respiratory culture as part of a sepsis workup irrespective of the patient's duration on invasive mechanical ventilation (IMV); 224 (88.2%) of providers preferred the endotracheal aspiration (ETA) technique to collect specimens. In cases where a positive respiratory culture was present, VAP (52.4%, 133) was the predominantly assigned diagnosis, followed by pneumonia (27.2%, 69) and ventilator-associated tracheitis (VAT) (9.8%, 25). Respondents reported a prescription of intravenous gentamicin (70%, 178) and vancomycin (41%, 105) as the initial empiric antibiotic drugs, pending final respiratory culture results. Most respondents (55.5%, 141) opted for seven days of antibiotics duration to treat VAP. The reported intra-departmental variation among colleagues in acquiring respiratory cultures and prescribing antibiotics for VAP was 48.8% (124) and 37.4% (95), respectively, with slightly more than half (53.5%, 136) of providers reporting having VAP prevention guidelines in their units. Conclusion The survey study revealed inconsistencies in the investigation, diagnostic nomenclature, choice of antibiotic, and treatment duration for neonatal VAP. Consequently, there is a pressing need for further research to establish a clear definition and evidence-based criteria for VAP.
ABSTRACT
Background: In children, nonadherence to inhaled corticosteroid (ICS) therapy leads to poor asthma control and complications. Methods: We evaluated the benefit from initiation of ICS administration once daily at school. We retrospectively chose patients from our pediatric pulmonary clinic who had poorly controlled asthma and prescribed ICS daily. For the study period, we examined the number of corticosteroid courses, emergency room visits, hospital admissions, symptom history, and pulmonary function tests. Results: Thirty-four patients who satisfied the inclusion criteria began the intervention. Preintervention, there were a mean number of 2.6 oral corticosteroid courses compared to 2 courses in the year following intervention (P = 0.8). Postintervention emergency department visits decreased from a mean of 1.4 to 1.0 (P = 0.71), and hospital admissions decreased from 1.23 to 0.57 (P = 0.04). There was also a significant increase in forced expiratory volume in 1 second (1.69 vs 1.4 L/sec, P = 0.02), a decrease in systemic steroid-free days in a year (96 vs 141 days, P = 0.03), and an increase in symptom-free days postintervention (28 vs 26 days, P = 0.325). Conclusion: These findings suggest that ICS administration in schools may help reduce hospital admissions and improve lung function in patients with poorly controlled asthma.
ABSTRACT
Asthma is a common chronic pediatric disease that negatively impacts the quality of patients' lives. While most cases can be effectively managed with a regimen of inhaled corticosteroids, severe cases require prolonged or frequent courses of oral corticosteroids or the addition of biologic therapies and allergen immunotherapy. Biologics are well tolerated with few side effects; however, reactions as severe as anaphylaxis have been reported. We present a pediatric patient with severe persistent asthma who developed hypersensitivity reactions to three different biologic agents.
ABSTRACT
Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) syndrome is a rare disease of concurrent respiratory dysfunction and autonomic dysregulation with endocrine abnormalities. ROHHADNET includes ROHHAD plus coexisting neuroendocrine tumors (NETs). We describe an eight-year-old boy, who originally presented at four years of age with rapid weight gain and hyperhidrosis and who developed mild obstructive sleep apnea (OSA). His clinical course was eventually complicated by hypoxic respiratory failure requiring admission to the pediatric intensive care unit (PICU). Echocardiogram at that time demonstrated dilated cardiomyopathy left ventricular ejection fraction (LVEF) of 28% at time of admission. His respiratory failure persisted despite average volume-assured pressure support (AVAPS) around the clock leading to tracheostomy placement for cardiopulmonary support. He also demonstrated autonomic instability with multiple pituitary hormone deficiencies. Computed tomography (CT) imaging of the abdomen and pelvis demonstrated a presacral soft tissue mass consistent with a tumor of neural crest origin. Daytime somnolence and confusion progressed and a low cerebrospinal fluid hypocretin level revealed a diagnosis of narcolepsy type 1.
ABSTRACT
OBJECTIVE: To determine the effect of preeclampsia on the development of bronchopulmonary dysplasia (BPD) in preterm infants. METHODS: Retrospective cohort study of infants' ≤32 weeks' gestation admitted to a level-IV single center neonatal intensive care unit from 2014 to 2016. Infants with major congenital anomalies, death or transfer before 28 days were excluded. Infants were stratified by maternal preeclampsia status. Demographic, clinical, and laboratory data were reviewed. Logistic regression was used to examine predictors for BPD. MAIN OUTCOME MEASURE: The primary outcome was BPD incidence. RESULTS: 432 infants met inclusion criteria; 22% developed BPD, of which, 16% had severe BPD. Thirty-eight percent of infants were born to preeclamptic mothers, with 23% of those infants developing BPD. Infants born to preeclamptic mothers were delivered by cesarean section (88% vs. 60%; p<0.0001) more often and had lower birthweight (Median=1265g, IQR 910-1555 vs. Median=1388g, IQR 959-1752; p=0.008) compared to infants born to non-preeclamptic mothers. Higher incidence of intrauterine growth restriction was noted in pre-eclampsia group,24% vs 8%, p=0.0001). Gestational age, length of stay and days on ventilator were all associated with the development of BPD. In multivariable logistic regression, preeclampsia was not a risk factor for development of BPD (OR 1.12 [0.68, 1.83]). CONCLUSIONS: Preeclampsia was not a significant risk factor for development of BPD nor the severity of BPD in infants' ≤32 weeks' gestation. IUGR infants with or without preeclampsia mothers were at higher risk for BPD.
ABSTRACT
The Sequential Organ Failure Assessment (SOFA) score is commonly used in the Intensive Care Unit (ICU) to evaluate, prognosticate and assess patients. Since its validation, the SOFA score has served in various settings, including medical, trauma, surgical, cardiac, and neurological ICUs. It has been a strong mortality predictor and literature over the years has documented the ability of the SOFA score to accurately distinguish survivors from non-survivors on admission. Over the years, multiple variations have been proposed to the SOFA score, which have led to the evolution of alternate validated scoring models replacing one or more components of the SOFA scoring system. Various SOFA based models have been used to evaluate specific clinical populations, such as patients with cardiac dysfunction, hepatic failure, renal failure, different races and public health illnesses, etc. This study is aimed to conduct a review of modifications in SOFA score in the past several years. We review the literature evaluating various modifications to the SOFA score such as modified SOFA, Modified SOFA, modified Cardiovascular SOFA, Extra-renal SOFA, Chronic Liver Failure SOFA, Mexican SOFA, quick SOFA, Lactic acid quick SOFA (LqSOFA), SOFA in hematological malignancies, SOFA with Richmond Agitation-Sedation scale and Pediatric SOFA. Various organ systems, their relevant scoring and the proposed modifications in each of these systems are presented in detail. There is a need to incorporate the most recent literature into the SOFA scoring system to make it more relevant and accurate in this rapidly evolving critical care environment. For future directions, we plan to put together most if not all updates in SOFA score and probably validate it in a large database a single institution and validate it in multisite data base.
ABSTRACT
Asthma is one of the leading causes of hospital admission in the pediatric population. Standardization of asthma management guidelines for patients admitted to the emergency department has been suggested to improve care delivery and patient outcomes. Utilizing a multidisciplinary asthma task force at a single academic medical center, we sought to determine if a protocol-driven approach to implementation of care for patients with asthma could improve patient outcomes by reducing wait times for administration of steroids. A prospective cohort study examined the use of a standardized asthma pathway over a 2-year period compared to historical controls. Pathway use significantly decreased time to corticosteroid administration (45 vs. 29 min [year 1] and 20 min [year 2]; P < 0.0001). By implementing this standard of care at pediatric emergency departments, time to treatment can be decreased, therefore improving the morbidity and mortality of pediatric patients with asthma nationwide.
ABSTRACT
This study sought to evaluate the benefit of asthma camp for patients who attended Baylor Scott & White McLane Children's Medical Center's Camp Wheeze Away in July 2016. Data were collected on children aged 8 to 15 years who were diagnosed with asthma and attended asthma camp. Information on body mass index, hospital admissions, and emergency department visits was collected 1 year before and 1 year after camp. Asthma control tests, exhaled nitric oxide tests, and pulmonary function tests were administered at the beginning and end of camp. A total of 34 children with asthma (mean age 11 [±2] years) were included in this study. Postcamp asthma-related hospitalizations and emergency department visits decreased. Mean asthma control scores improved from 20.4 (±3.2) before camp to 23.4 (±2.8) after camp (P < 0.0001). Forced expiratory volume during the first breath and forced expiratory flow at 25% to 75% of the pulmonary volume improved during the weeklong camp (P = 0.04 and 0.0007, respectively). Forced expiratory volume during the first breath further improved 6 to 12 months after camp compared to values before camp (P = 0.047). Exhaled nitric oxide levels improved from the first to last day of camp by decreasing an average of 39% (P = 0.0009). This study showed the positive effect that a short-term educational intervention in a camp setting had on asthma control scores and asthma knowledge.
ABSTRACT
The case of a 10-year-old child with sickle cell disease with pulmonary nodules and prolonged fevers is reported here. The child was first diagnosed with sarcoidosis based on lung biopsy, but unresponsiveness to therapy led to a second lung biopsy, which revealed the true diagnosis of mycobacterium avium complex disease. Multiple possible explanations for why the patient became infected exist. The patient was baseline immunocompromised due to her sickle cell disease, was exposed to invasive procedures, was taking medications that may predispose to this type of infection, and was found to have a congenital immunodeficiency.

Chronic eosinophilic pneumonia (CEP) is an eosinophilic lung disease that is typically diagnosed by a triad of clinical symptoms including pulmonary symptoms, eosinophilia and characteristic radiographic abnormalities. It requires a high index of suspicion given its overlap with other eosinophilic conditions and lack of a specific diagnostic test. The diagnosis is made after careful consideration of other secondary causes of eosinophilia, such as infectious, drugs, or toxic etiologies. CEP generally responds rapidly to treatment, which primarily consists of corticosteroid therapy, but relapses are common. Novel therapies are being explored as more information is being discovered about the pathophysiology of eosinophilic disease processes. Close follow-up is important given the difficulty in weaning patients from glucocorticoids with many patients developing sequelae of chronic glucocorticoid therapy. Therefore, exploring alternative treatments is of upmost importance.
ABSTRACT
Ductal origin of pulmonary artery is a rare anomaly that is frequently misdiagnosed. Patients may present with exertional dyspnoea, recurrent respiratory infections and pulmonary hypertension. The presence of pulmonary hypertension can adversely affect clinical outcome in these patients; hence, early identification and intervention is the key to improve survival. A case of a 3-year-old child presenting with exertional dyspnoea is presented in this report. Chest radiograph revealed right-sided pulmonary hypoplasia and mediastinal shift to the right. Pulmonary artery agenesis was suspected when CT of the chest demonstrated right-sided pulmonary artery agenesis. Cardiac catheterisation revealed the correct diagnosis of ductal origin of right pulmonary artery. The most striking feature of this case is that the clinical presentation is mild compared with the findings on imaging.

We assessed the association between antibiotic exposure in the first 2 weeks of life and development of bronchopulmonary dysplasia in a cohort of very low birth weight infants. After controlling for the severity of illness, each additional day of antibiotic therapy was associated with both an increased risk for and severity of bronchopulmonary dysplasia.

Nonaccidental trauma (NAT) is common and presents with varied symptoms. Pleural effusion as a complication of physical abuse has not been described in the past. We report the case of a 10-week-old infant who presented with multiple nonspecific complaints that included respiratory distress, refusal to feed, constipation, and lethargy. Sepsis was the working diagnosis on admission, but a massive pleural effusion and rib fractures seen on chest imaging ultimately led to the diagnosis of nonaccidental trauma. This interesting case highlights the importance of maintaining a high index of suspicion for abuse irrespective of atypical presenting signs.

We have reported previously the activity of the insulin-like growth factor-I (IGF-IR)/insulin receptor (InsR) inhibitor, BMS-554417, in breast and ovarian cancer cell lines. Further studies indicated treatment of OV202 ovarian cancer cells with BMS-554417 increased phosphorylation of HER-2. In addition, treatment with the pan-HER inhibitor, BMS-599626, resulted in increased phosphorylation of IGF-IR, suggesting a reciprocal cross-talk mechanism. In a panel of five ovarian cancer cell lines, simultaneous treatment with the IGF-IR/InsR inhibitor, BMS-536924 and BMS-599626, resulted in a synergistic antiproliferative effect. Furthermore, combination therapy decreased AKT and extracellular signal-regulated kinase activation and increased biochemical and nuclear morphologic changes consistent with apoptosis compared with either agent alone. In response to treatment with BMS-536924, increased expression and activation of various members of the HER family of receptors were seen in all five ovarian cancer cell lines, suggesting that inhibition of IGF-IR/InsR results in adaptive up-regulation of the HER pathway. Using MCF-7 breast cancer cell variants that overexpressed HER-1 or HER-2, we then tested the hypothesis that HER receptor expression is sufficient to confer resistance to IGF-IR-targeted therapy. In the presence of activating ligands epidermal growth factor or heregulin, respectively, MCF-7 cells expressing HER-1 or HER-2 were resistant to BMS-536924 as determined in a proliferation and clonogenic assay. These data suggested that simultaneous treatment with inhibitors of the IGF-I and HER family of receptors may be an effective strategy for clinical investigations of IGF-IR inhibitors in breast and ovarian cancer and that targeting HER-1 and HER-2 may overcome clinical resistance to IGF-IR inhibitors.
