Objectives: Although human bocavirus (HBoV) is primarily linked to respiratory tract infections, its exact role as a respiratory pathogen remains unclear. This study aims to investigate HBoV detection rates, as well as clinical, laboratory, microbiological, and radiological characteristics, length of stay in the emergency department (ED), rate of hospitalization, and severity of illness in cases where HBoV is detected in respiratory secretions., Methods: We conducted a retrospective analysis of all consecutive patients under 18 years who visited a large-volume tertiary pediatric ED from January to December 2023 and tested positive for HBoV in their respiratory viral panel (RVP)., Results: Among the 14,315 patients who underwent RVP testing during the study period, 591 (4%) tested positive for HBoV. After excluding those with incomplete data, 528 patients (57% male) were included in the analyses. The median age was 2.8 [1.2-4.9] years. The most common symptoms were cough (67%), fever (58%), runny nose/nasal congestion/sore throat (34%), and respiratory distress (24%). Thirty percent of the patients had a history of antibiotic use before admission. Thirteen percent of the patients had at least one chronic illness. Co-infection with HBoV occurred in 37% of the patients, with respiratory syncytial virus (RSV) being the most frequently co-detected virus (45%). Lymphopenia was documented in 12% of patients, and 36% had elevated C-reactive protein levels (median 21 [12-38] g/dl). Abnormal chest X-rays were noted in 85% of patients. The management approach included outpatient care for more than half of the patients (69%). Clinical severity was classified as high in 11% of patients ( n  = 60), necessitating ICU admission., Conclusion: Although typically mild, HBoV infections can escalate to severe respiratory illnesses, requiring respiratory support and intensive care.

Objectives: Over-testing and over-treatment are common in children with croup at pediatric emergency departments (PED). The objective of the study was to improve care for children with croup., Methods: In this quality improvement (QI) initiative, all pediatric residents starting their rotation in the PED attended an informative presentation about croup and were provided reminders throughout their rotation. The primary outcome of this QI initiative was to reduce nebulized epinephrine (NE) use among children with mild croup by 50% over 7 months. The secondary outcome was to reduce X-rays by 50% over 7 months. Other outcomes included the administration of dexamethasone to all children with croup, reduction of antibiotics, laboratory tests, and revisits, and shortening the duration between physical examination to dexamethasone and NE treatments, and the length of stay (LOS) at the PED., Results: NE administration to patients with mild croup decreased from 80.2% to 36.3% ( p  < 0.001). The proportion of children with X-rays decreased from 37.4% to 17.1% ( p  < 0.001). There was a significant increase in dexamethasone administration, and significant decreases in laboratory blood tests, expanded viral PCR panel tests, and antibiotic prescription among all croup cases ( p  < 0.001). Revisit rates were not significantly different ( p  > 0.05). Time to dexamethasone and LOS shortened significantly ( p  < 0.001)., Conclusion: With this QI intervention, decreases in the rate of administration of NE to mild croup cases, antibiotic prescription, X-ray, laboratory blood and respiratory PCR panel tests in all croup cases were achieved without an increase in revisits. However, unnecessary NE, antibiotic, and X-ray rates are still high.

Objective: This study was conducted to reveal the characteristics of pediatric emergency revisits of children with COVID-19 and the factors associated with clinical worsening and hospitalization at the revisit., Materials and Methods: In pediatric emergency visits of children between July 2020 and March 2021 with COVID-19, the patients who had a revisit within 7 days were included in the study. Demographic and clinical characteristics, test results, and the relationship of these variables with clinical worsening and hospitalization at the revisit were investigated., Results: In 6779 children with COVID-19, 284 (4.1%) patients included in the study. 51.8% of the patients were male, the median age was 11.1 years, and median time to revisit time was 2.0 days. The rates of clinical worsening and hospitalization were 9.1% and 14.7%, respectively. Children younger than 24 months and those with chronic diseases were more commonly hospitalized at the revisit. Though the frequency of laboratory and radiologic testing at the revisit was significantly increased compared to the first presentation, tests did not play an important role in the decision-making processes. More than 85% of patients were clinically mild at the first presentation and revisit., Conclusions: Children with a diagnosis of COVID-19 can revisit the emergency without evident clinical worsening. Since revisits cause increase in frequency of laboratory and radiological testing, preventing unnecessary revisits of children with COVID-19 can reduce the workload and cost of health care services. We may consider changing our perspective on revisit patients to make decisions based on clinical findings instead of obtaining for more laboratory tests.

Objectives: Syncope is a common presenting symptom in the pediatric emergency department (PED). The etiology of pediatric syncope is generally benign. However, differentiating cardiac and other serious causes from benign causes of syncope are crucial. The aim of this study was to evaluate the change of physicians' behavior after introduction of an institutional protocol designed to act as a guide in the assessment and management of syncope patients in the PED., Methods: This was a retrospective study, conducted at the PED of our University Children's Hospital. A "pediatric syncope approach protocol" was introduced on March 1, 2019 for quality improvement purposes. Documented information in the medical records, laboratory investigations and the patients' final diagnoses during the six-month periods before and after the protocol introduction were compared., Results: 268 patients were included in the study (131 pre-protocol, 137 post-protocol patients). When compared with the pre-protocol group, there was a significant improvement in the documentation of syncope characteristics (prodromal findings, predisposing factors, association with exercise), cardiac, neurological and electrocardiographic (ECG) warning signs and ordering of cardiac markers in the post-protocol group., Conclusions: The introduction of the syncope approach protocol in PED has enabled an evidence-based and systematic evaluation and management of syncope patients, and reduced the rates of low-yield investigations. Sustained implementation of this protocol can have long-term benefits in the care of children with syncope at the emergency department., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2022 Elsevier Inc.

Objectives: Acute bronchiolitis and community-acquired pneumonia are the most common acute lower respiratory infections (LRIs) leading to emergency admission and hospitalization in children. The aim of this study is to investigate clinical, laboratory, and radiology findings; diagnostic and therapeutic decisions; and the relationships between them in patients younger than 2 years of age, hospitalized for LRI., Methods: Patients hospitalized for acute LRI (aged 28 days to 24 months) between November 1, 2017, and March 31, 2018, at a referral hospital were included. Patients' characteristics, clinical, laboratory, and radiologic findings and diagnostic and therapeutic decisions, along with reason for hospitalization, were recorded retrospectively. Chest x-rays were reinterpreted by the pediatric radiologist. Associations of these data with the radiologic signs and treatment modalities including antibiotics, bronchodilators, and high-flow oxygen therapy (HFOT) were assessed., Results: One hundred eighty-two patients were included. One hundred sixty (87.9%) had at least one of the following criteria for hospitalization: dehydration, feeding difficulties, young age (<12 weeks), and hypoxia. One hundred forty-five (79.6%) and 71 (39.0%) patients were administered antibiotic and antiviral therapy, respectively. Twenty-three patients (13.7%) were given HFOT, and 179 (99.4%) were given bronchodilators. None of the complaints, physical signs, or laboratory parameters had statistically significant associations with radiologic findings (P > 0.05). History of wheezing and presence of rales and dehydration in physical examination were associated with antibiotic use (P < 0.001)., Conclusions: The decision of hospitalization was generally appropriate. However, laboratory and radiologic tests and treatments including HFOT, bronchodilator, antibiotic, and antiviral therapies were used excessively and inefficiently. Physicians' decisions were not based on evidence or on the clinical findings of the patient. The results of this study should prompt investigations into the reasons underlying these clinical decisions and development of practice models that can provide solutions specifically targeting the decision-making processes of physicians caring for young children with LRI at the emergency department., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Haemolacria, also known as bloody tears, is a physical condition in which a person produces tears partially composed of blood. Multiple disorders can cause haemolacria, including trauma, inflammation, vascular lesions, vicarious menstruation, blood disorders, epistaxis, tumours and psychiatric and systemic disorders. Often, no aetiology is identified. It is usually benign, self-limiting, and the treatment depends on the cause. A 14-year-old girl presented to the paediatric emergency department with sudden onset of bloody tears from both eyes and epistaxis for the first time. A detailed history focusing on aetiological factors was unremarkable. Systemic, ocular, nasal and paranasal examination was also unremarkable. Radiological and laboratory investigations were normal, and the patient was diagnosed with idiopathic haemolacria. High-dose oral vitamin C, prophylactic iron therapy and psychological support were provided as conservative treatment. During regular follow-up, there was a spontaneous reduction in the frequency of symptoms.

Objective: Carbon monoxide (CO) is a gas, which is produced by incomplete combustion of hydrocarbon-containing substances, and causes significant tissue and organ damage in the common event of CO poisoning. This study aims to evaluate the demographic, clinical, and laboratory characteristics of patients diagnosed with CO poisoning in the emergency department and to determine the factors associated with severe course in the acute phase of poisoning., Methods: A total of 331 patients diagnosed with CO poisoning in Hacettepe University Children's Hospital, Pediatric Emergency Unit, between January 2004 and March 2014 were included in the study. Their demographic characteristics, presenting complaints, physical examination findings, Glasgow Coma Scale scores, carboxyhemoglobin, leukocyte, hemoglobin, troponin T, pH and lactate levels, type of treatment (normobaric or hyperbaric oxygen), intensive care unit admissions, and outcome of poisoning were investigated., Results: Ninety-three patients were given hyperbaric oxygen. Fifty-one patients were admitted to the pediatric intensive care unit, 18 patients have had a severe clinical course, and 6 patients have died. The risk factors associated with severe disease course were determined to be low Glasgow Coma Scale score, high leukocyte count, and high troponin T levels at presentation., Conclusions: Glasgow Coma Scale score, leukocyte count, and troponin T level may be beneficial in predicting clinical outcomes and tailoring therapy in children with CO poisoning., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2018 Wolters Kluwer Health, Inc.
