Cross-Sectional Study of Soil-Transmitted Helminthiases in Black Belt Region of Alabama, USA.

We conducted a cross-sectional study to determine the prevalence of soil-transmitted helminthiases (STH) in areas of rural Alabama, USA, that have sanitation deficits. We enrolled 777 children; 704 submitted stool specimens and 227 a dried blood spot sample. We microscopically examined stool specimens from all 704 children by using Mini-FLOTAC for helminth eggs. We tested a subset by using molecular techniques: real-time PCR analysis for 5 STH species, TaqMan Array Cards for enteric helminths, and digital PCR for Necator americanus hookworm. We analyzed dried blood spots for Strongyloides stercoralis and Toxocara spp. roundworms by using serologic testing. Despite 12% of our cohort reporting living in homes that directly discharge untreated domestic wastewater, stool testing for STH was negative; however, 5% of dried blood spots were positive for Toxocara spp. roundworms. Survey data suggests substantial numbers of children in this region may be exposed to raw sewage, which is itself a major public health concern.

Roseomonas gilardii Bacteremia in a Patient With HbSß0-thalassemia: Clinical Implications and Literature Review.

Roseomonas gilardii is a Gram-negative coccobacillus identified in immunocompromised pediatric patients. A 5-year-old male with a history of HbSß thalassemia status postsurgical splenectomy presented to the emergency department with fever. Blood cultures grew R. gilardii at 63 hours, but the patient had been discharged home at 48 hours. The patient was readmitted for repeat cultures and initiated on meropenem for 10 days as Roseomonas spp. are often resistant to third generation cephalosporins. R. gilardii is a rare cause of bacteremia in immunocompromised patients. Clinicians should consider Roseomonas in slow growing Gram-negative rod bacteremias, and consider meropenem as empiric coverage.

Pathogenesis of Non-Zika Congenital Viral Infections.

A widespread epidemic of Zika virus (ZIKV) infection was reported in 2015 from South and Central America and the Caribbean. Although the full spectrum of ZIKV infection of the newborn has yet to be determined, other maternal viral infections resulting in transmission to the fetus provide instructive lessons that can be applied to the prospective evaluation of individuals with ZIKV infection. This review focuses on those other congenital infections, including rubella, congenital cytomegalovirus, human immunodeficiency virus, hepatitis B virus, and neonatal herpes simplex virus, from which lessons for the evaluation of ZIKV in the newborn can be applied.

Water and Sanitation Access for Children in Alabama.

BACKGROUND AND OBJECTIVES: Safe drinking water and closed sanitation are fundamental to health and are assumed in the United States, however, gaps remain, disproportionately affecting marginalized communities. We sought to describe household sanitation access for children in rural Alabama and local health provider knowledge of sanitation related health concerns. METHODS: Data were collected from self-administered surveys obtained from children enrolled in a larger cross-sectional study to determine soil transmitted helminthiasis prevalence in Alabama, from a survey of health providers from local federally qualified health centers and from a baseline knowledge check of Alabama health providers enrolled in an online sanitation health course. RESULTS: Surveys completed on 771 children (approximately 10% of county pediatric population) revealed less than half lived in homes connected to centralized sewers; 12% reported "straight-pipes," a method of discharging untreated sewage to the ground outside the home, and 8% reported sewage contamination of their home property in the past year. Additionally, 15% of respondents were likely to use well water. The local health providers surveyed did not include routine screening for water and sanitation failures or associated infections. Regional healthcare providers have limited knowledge of soil transmitted helminthiasis. CONCLUSIONS: A significant number of children from rural counties of Alabama with high rates of poverty reside in homes with water and sanitation challenges that predominantly affect African American families. This is an under-recognized health risk by local health providers, and its contribution to well-documented health disparities in this region is poorly understood.

Impact of Severe Acute Respiratory Syndrome Coronavirus 2 Variants on Short- and Mid-term Cardiac Outcomes in Multisystem Inflammatory Syndrome in Children.

Cardiac outcomes of 131 children with multisystem inflammatory syndrome (MIS-C) were examined. The majority of the cohort was male (66.4%) and half were Black (49.6%). Cardiac involvement was evident in 25% of the cohort at diagnosis. Favorable short- and mid-term outcomes were documented on follow-up, irrespective of the severe acute respiratory syndrome coronavirus 2 variants causing the infection.

Virological Characteristics of Hospitalized Children With SARS-CoV-2 Infection.

BACKGROUND AND OBJECTIVES: In children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, virological characteristics and correlation with disease severity have not been extensively studied. The primary objective in this study is to determine the correlation between SARS-CoV-2 viral load (VL) in infected children with age, disease severity, and underlying comorbidities. METHODS: Children <21 years, screened for SARS-CoV-2 at the time of hospitalization, who tested positive by polymerase chain reaction were included in this study. VL at different sites was determined and compared between groups. RESULTS: Of the 102 children included in this study, 44% of the cohort had asymptomatic infection, and children with >1 comorbidity were the most at risk for severe disease. VL in children with symptomatic infection was significantly higher than in children with asymptomatic infection (3.0 × 105 vs 7.2 × 103 copies per mL; P = .001). VL in the respiratory tract was significantly higher in children <1 year, compared with older children (3.3 × 107 vs 1.3 × 104 copies per mL respectively; P < .0001), despite most infants presenting with milder illness. Besides the respiratory tract, SARS-CoV-2 RNA was also detectable in samples from the gastrointestinal tract (saliva and rectum) and blood. In 13 children for whom data on duration of polymerase chain reaction positivity was available, 12 of 13 tested positive 2 weeks after initial diagnosis, and 6 of 13 continued to test positive 4 weeks after initial diagnosis. CONCLUSIONS: In hospitalized children with SARS-CoV-2, those with >1 comorbid condition experienced severe disease. SARS-CoV-2 VL in the respiratory tract is significantly higher in children with symptomatic disease and children <1 year of age.

Management of Cepacia Syndrome With a Combination of Intravenous and Inhaled Antimicrobials in a Non-Cystic Fibrosis Pediatric Patient.

Burkholderia cepacia complex (Bcc) is an opportunistic pathogen, posing little risk to healthy individuals. The presentation of Bcc can vary from a virtually asymptomatic chronic infection, to an acute, life-threatening necrotizing pneumonia, acute respiratory distress syndrome, and bacteremia (cepacia syndrome) associated with a mortality rate up to 75%. We present the successful treatment of a 17-year-old male with chronic granulomatous disorder who presented with cepacia syndrome and confirmed Bcc pneumonia using a novel antimicrobial approach. Despite initial IV antimicrobial therapy, our patient continued to decline, developing hypotension requiring pressor support and eventually extracorporeal membrane oxygenation. An aggressive, multimechanistic approach including the combination of nebulized tobramycin, IV sulfamethoxazole-trimethoprim, ceftazidime, enteral minocycline, and corticosteroids was implemented. This multimechanistic antimicrobial approach in combination with systemic corticosteroids led to the successful treatment of cepacia syndrome in the setting of necrotizing pneumonia due to B cepacia with full respiratory recovery. We suggest that in patients with cepacia syndrome who continue to decline despite IV antimicrobial therapy, using multiple antimicrobial mechanisms of action may improve clinical outcomes.

Severe Neonatal Coronavirus Disease 2019 Presenting as Acute Respiratory Distress Syndrome.

Since initial identification of severe acute respiratory syndrome coronavirus 2 in 2019, the virus has proved to be highly transmissible, resulting in a global pandemic with emerging reports of infected neonates. This report highlights a severe case of neonatal coronavirus disease 2019 with acute respiratory distress syndrome.

Hospital-acquired viral respiratory infections in neonates hospitalized since birth in a tertiary neonatal intensive care unit.

OBJECTIVE: To determine frequency of hospital-acquired viral respiratory infections (HA-VRI) and associated outcomes in a NICU. STUDY DESIGN: Prospective cohort study conducted from 4 October 2016 to 21 March 2017. Infants hospitalized from birth in the NICU had a weekly nasal swab collected for testing using a multiplex PCR assay capable of detecting 16 different respiratory viruses. RESULTS: Seventy-four infants enrolled, with 5 (6.8%) testing positive for a virus (incidence rate of 1.3/1000 patient days). VRI positive infants had a younger gestational age (median 27 w vs. 32 w, p = 0.048); were hospitalized longer (97 d vs 43 d, p = 0.013); required more antibiotics (8 d vs. 4 d, p = 0.037) and were more likely to be diagnosed with bronchopulmonary dysplasia (p = 0.008) compared to VRI negative infants. CONCLUSION: Respiratory viruses are a frequent cause of HAI in the NICU and are associated with negative outcomes.

Antiviral Therapies for Herpesviruses: Current Agents and New Directions.

PURPOSE: The objective of this review was to summarize the recent literature describing the current burden of disease due to herpesviruses in the antiviral and transplant era; describe mechanisms of action of antiviral agents and the development of resistance; summarize the literature of recent antiviral agents brought to market as well as agents under development; and to present literature on future strategies for herpesvirus therapeutics. METHODS: An extensive search of the medical literature related to antiherpesviral therapy was conducted to compose this narrative review. Literature searches were performed via PubMed and ultimately 137 articles were included as most relevant to the scope of this article. FINDINGS: Herpesviruses are a family of DNA viruses that are ubiquitous throughout human populations and share the feature of establishing lifelong infections in a latent phase with the potential of periodic reactivation. With the exception of herpes simplex virus, varicella zoster virus, and Epstein-Barr virus, which have a significant disease burden in individuals with normal immune function, the morbidity and mortality of the remaining viruses are primarily associated with the immunocompromised host. Over the last half-century, several agents have been tested in large randomized, placebo-controlled trials that have resulted in safe and effective antiviral agents for the treatment of many of these infections. IMPLICATIONS: With increasing use of antiherpesviral agents for extended periods, particularly in immunocompromised hosts, the emergence of resistant viruses has necessitated the development of newer agents with novel targets and better side-effect profiles.

Antiviral Approaches for the Treatment of Herpes Simplex Virus Infections in Newborn Infants.

Herpes simplex virus (HSV) infections in newborns are associated with severe disease and death. Trials conducted by the Collaborative Antiviral Study Group have established the standard of care for the treatment of neonatal HSV disease with marked improvements in morbidity and mortality. We review the studies that have contributed to our understanding of the epidemiology and clinical course of neonatal HSV disease and discuss the landmark trials that have resulted in safe and effective treatment together with improved diagnostics. Although significant advances have been made, neonatal HSV disease continues to have an unacceptably high mortality rate with significant sequelae in survivors. Further research is urgently needed for prevention.

The patient categories addressed are treatment and prophylaxis of influenza, neonatal herpes simplex virus and congenital cytomegalovirus, treatment and prophylaxis of viral disease in the immunocompromised host, and a brief introduction to the antivirals available to treat hepatitis B and hepatitis C in children.

Characterization of the Development of Acute-on-Chronic Exertional Compartment Syndrome A Case Report of Symmetric Compartment Syndromes and Review of the Literature.

Acute-on-chronic exertional compartment syndrome is a rare and severe progression of the likely common and more benign chronic exertional compartment syndrome. This is a report of one 17-year-old male on a pediatric inpatient service with bilateral anterior leg pain of unknown origin. Because of the nonspecific nature of pain, a high level of suspicion is required for timely diagnosis to avoid compartment ischemia and irreversible soft tissue and nerve damage. While high-energy orthopaedic trauma, orthopaedic surgery, or closed reduction and casting are common preceding events for compartment syndrome, this patient presented with acute-on-chronic exertional compartment syndrome. A dearth of literature of this condition hampered its morbiditysparing diagnosis. While there is a spectrum of clinical findings for the acute decompensation of chronic exertional compartment syndrome, like any compartment syndrome, pain disproportionate to physical exam is the most sensitive sign. Understanding the exertional compartment syndrome spectrum is tantamount to avoid the devastating complications of a missed diagnosis of acute compartment syndrome.

Nocturnal Anxiety in a Youth with Rapid-onset Obesity, Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation (ROHHAD).

OBJECTIVE: Behavioral and psychiatric disorders are common in youth with rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD). We outline a rational approach to psychiatric treatment of a patient with a complex medical condition. METHODS: We report the course of symptoms in a teen with ROHHAD, the inpatient treatment, and review current evidence for use of psychopharmacologic agents in youth with sleep and anxiety disturbances. RESULTS: A 14-year-old female began rapidly gaining weight as a preschooler, developed hormonal imbalance, and mixed sleep apnea. Consultation was requested after a month of ROHHAD exacerbation, with severe anxiety, insomnia, and auditory hallucinations. Olanzapine and citalopram were helpful in controlling the symptoms. Following discharge, the patient gained weight and olanzapine was discontinued. Lorazepam was started in coordination with pulmonary service. Relevant pharmacologic considerations included risk of respiratory suppression, history of paradoxical reaction to hypnotics, hepatic isoenzyme interactions and side effects of antipsychotics. CONCLUSIONS: Core symptoms of ROHHAD may precipitate psychiatric disorders. A systematic evidence-based approach to psychopharmacology is necessary in the setting of psychiatric consultation.

OBJECTIF: Les troubles comportementaux et psychiatriques sont fréquents chez les adolescents souffrant du syndrome d'obésité infantile d'installation rapide-dysfonctionnement hypothalamique-hypoventilation-dysautonomie (ROHHAD). Nous présentons une approche rationnelle de traitement psychiatrique d'une patiente souffrant d'une affection médicale complexe. MÉTHODES: Nous rendons compte de l'évolution des symptômes chez une adolescente souffrant du syndrome ROHHAD et du traitement de la patiente hospitalisée, et nous examinons les données probantes actuelles sur l'utilisation d'agents psychopharmacologiques chez les adolescents souffrant de perturbations du sommeil et d'anxiété. RÉSULTATS: Une adolescente de 14 ans s'est mise à prendre rapidement du poids en âge préscolaire, a développé un déséquilibre hormonal, et une apnée du sommeil mixte. Une consultation a été demandée après un mois d'exacerbation du ROHHAD, avec grave anxiété, insomnie, et hallucinations auditives. L'olanzapine et le citalopram ont aidé à contrôler les symptômes. Après son congé, la patiente a pris du poids et cessé l'olanzapine. Le lorazépam a été initié en coordination avec un service de pneumologie. Les considérations pharmacologiques pertinentes étaient notamment le risque de suppression respiratoire, les antécédents de réaction paradoxale aux hypnotiques, les interactions de l'isoenzyme hépatique, et les effets secondaires des antipsychotiques. CONCLUSIONS: Les symptômes de base du syndrome ROHHAD peuvent précipiter les troubles psychiatriques. Une approche systématique de la psychopharmacologie fondée sur les données probantes est nécessaire dans le contexte de la consultation psychiatrique.
