Medical errors during training: how do residents cope?: a descriptive study.

Background: Physicians' self-perceived medical errors lead to substantial emotional distress, which has been termed the "second victim phenomenon." Medical errors during residency are associated with increased burnout and depression. It is important to know how residents cope with self-perceived medical errors and how they gain personal and emotional support in order to develop effective interventions.

Azithromycin treatment in children hospitalized with asthma: a retrospective cohort study.

Azithromycin has anti-inflammatory properties in the lungs and decreases the duration of asthma-like episodes in children. We sought to evaluate length of stay (LOS) and readmission rates of children receiving azithromycin therapy during hospitalization for acute asthma exacerbations. This was a retrospective cohort study at an urban, quaternary-care children's hospital including patients under 18 years old hospitalized for asthma, without concurrent infection, from 2002 to 2011.

Safety of High-Flow Nasal Cannula Outside the ICU for Previously Healthy Children With Bronchiolitis.

Background: High-flow nasal cannula (HFNC), a form of noninvasive respiratory support, is effective for the treatment of respiratory distress in ICUs. Although HFNC has been used outside of the ICU, there is little research that examines its safety in this less-monitored setting.

Methods: Children ≤ 24 months old admitted with bronchiolitis to a pediatric floor at a tertiary care center from April 1 2013, to March 31 2015, were identified by using standard diagnostic codes.

Radiation Exposure of Premature Infants Beyond the Perinatal Period.

Objectives: To determine the odds of premature compared with term infants exceeding the recommended radiation exposure threshold in the first year after discharge from birth hospitalization.

Methods: In this observational retrospective cohort study, we compared the radiation exposure of premature and term infants between 2008 and 2015 in an urban hospital system. The primary outcome was crossing the radiation exposure threshold of 1 millisievert.

Clinical Factors Associated With Chest Imaging Findings in Hospitalized Infants With Bronchiolitis.

Despite recommendations against routine imaging, chest radiography (CXR) is frequently performed on infants hospitalized for bronchiolitis. We conducted a review of 811 infants hospitalized for bronchiolitis to identify clinical factors associated with imaging findings. CXR was performed on 553 (68%) infants either on presentation or during hospitalization; 466 readings (84%) were normal or consistent with viral illness.

Risk Factors for Respiratory Decompensation Among Healthy Infants With Bronchiolitis.

Background: Although most children with bronchiolitis only require supportive care, some decompensate and require ventilatory support. We examined predictors of respiratory decompensation among hospitalized children to identify which patients may benefit from expectant monitoring.

Methods: We examined children ≤24 months old with bronchiolitis admitted to the general infant and toddler floor.

3% Hypertonic Saline Versus Normal Saline in Inpatient Bronchiolitis: A Randomized Controlled Trial.

Background And Objectives: Bronchiolitis, the most common reason for hospitalization in children younger than 1 year in the United States, has no proven therapies effective beyond supportive care. We aimed to investigate the effect of nebulized 3% hypertonic saline (HS) compared with nebulized normal saline (NS) on length of stay (LOS) in infants hospitalized with bronchiolitis.

Methods: We conducted a prospective, randomized, double-blind, controlled trial in an urban tertiary care children's hospital in 227 infants younger than 12 months old admitted with a diagnosis of bronchiolitis (190 completed the study); 113 infants were randomized to HS (93 completed the study), and 114 to NS (97 completed the study).

L-carnitine supplementation in patients with HIV/AIDS and fatigue: a double-blind, placebo-controlled pilot study.

Background: The purpose of this study was to determine the effect of L-carnitine supplementation on fatigue in patients with terminal human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS).

Methods: In this randomized, double-blind, placebo-controlled, parallel-group study, patients who had end-stage HIV/AIDS with carnitine deficiency and fatigue received 3 g of oral L-carnitine or placebo for 2 weeks, followed by a 2-week, open-label phase with the same amount of L-carnitine for all patients. The primary outcome was the degree of fatigue according to the Brief Fatigue Inventory.

Zidovudine (AZT) overdose in a healthy newborn receiving postnatal prophylaxis.

Context: Pediatric medication dosing and administration, faced with inherent challenges of dose to body weight adjustment and variable delivery vehicles, may lead to inadvertent errors effectively resulting in overdose. Zidovudine (AZT), a nucleoside analog reverse transcriptase inhibitor (NRTI), is a commonly prescribed medication to treat HIV-exposed newborns, with limited overdose data in this patient population. Metabolic acidosis with elevated lactate is the most serious consequence of AZT toxicity in the adult population, associated with mortality.

A cluster of children with seizures caused by camphor poisoning.

Background: Isolated cases of camphor-induced seizures have been reported in young children after gastrointestinal, dermal, and inhalation exposure. In 1982, after a series of unintentional ingestions of camphor products, the US Food and Drug Administration restricted the camphor content to <11% in some products intended for medicinal use. Camphor products intended for use as pesticides must be registered with the US Environmental Protection Agency.

L-carnitine supplementation in patients with advanced cancer and carnitine deficiency: a double-blind, placebo-controlled study.

Carnitine deficiency is prevalent in populations with chronic illness, including cancer. In a recent open-label study, L-carnitine supplementation was well tolerated and appeared to improve fatigue and other outcomes in cancer patients. To further evaluate this finding, adult patients with advanced cancer, carnitine deficiency (free carnitine more than 35 micromol/L for males or less than 25 micromol/L for females, or acyl/free carnitine ratio of more than 0.

Safety, tolerability and symptom outcomes associated with L-carnitine supplementation in patients with cancer, fatigue, and carnitine deficiency: a phase I/II study.

Carnitine deficiency is among the many metabolic disturbances that may contribute to fatigue in patients with cancer. Administration of exogenous L-carnitine may hold promise as a treatment for this common symptom. Little is known about L-carnitine safety, tolerability, and dose-response in patients with cancer.

The use of levo-carnitine in children with renal disease: a review and a call for future studies.

Carnitine is an amino acid derivative that has a key role in the regulation of fatty acid metabolism and ATP formation. Carnitine deficiency has been described in various conditions, including chronic kidney disease (CKD) and end stage renal disease (ESRD). The deficiency of this micronutrient is postulated to lead to adverse effects across multiple organ systems.

Pivotal role of Harakiri in the induction and prevention of gentamicin-induced hearing loss.

Gentamicin is a widely used ototoxic agent. In this study, we shed light on the mechanisms underlying gentamicin-induced hearing loss. More importantly, we demonstrate in vivo and in vitro the effectiveness of a strategy for preventing drug-induced hearing loss using l-carnitine (LCAR), a safe micronutrient that plays a key role in energy metabolism and detoxification [Rebouche, C.

Lack of effect of L-carnitine supplementation on weight gain in very preterm infants.

Objective: Carnitine transfer across the placenta occurs predominantly during the third trimester. Unless L-carnitine is provided, very preterm infants develop carnitine deficiency. Although breast milk and infant formulas contain L-carnitine, parenteral nutrition solutions do not routinely provide L-carnitine.

Cisplatin-induced apoptosis in auditory cells: role of death receptor and mitochondrial pathways.

Cisplatin, a commonly used chemotherapeutic agent, has a major limitation due to its ototoxicity. Previous studies have shown that cisplatin induces apoptosis in auditory sensory cells, but the underlying mechanisms remain to be elucidated. In this study, cisplatin was found to induce apoptosis in a cochlear cell line, in a dose- and duration-dependent manner.
