Interplay between carotid artery dissection and thrombophilia leading to ischaemic stroke after minor head trauma in an adolescent: a case report.

Stroke in children is more common than is often realised; there are numerous potential causes, including carotid artery injury resulting from minor head or neck trauma, as well as genetic conditions associated with thrombophilia. A 13-year-old boy suffered an arterial ischaemic stroke (AIS) secondary to dissection of the left internal carotid artery (ICA) after he headed the ball during a game of football. He presented with generalised tonic-clonic seizure, loss of consciousness, right-sided hemiplegia and aphasia. Neuroradiological imaging showed left caudate, putaminal and posterior insular ischaemic infarct secondary to complete occlusion of the left ICA and accompanying partial left middle cerebral artery occlusion. He was treated with anticoagulant and anti-aggregant agents. Rarely, minor head trauma can result in internal carotid artery dissection, thrombus formation and arterial occlusion, leading to arterial ischaemic stroke. Prompt diagnosis and management are crucial to achieve a good neurological outcome.Abbreviations: AIS: arterial ischaemic stroke; ANA: anti-nuclear antibody; APA: anti-phospholipid antibody; APTT: activated partial thromboplastin time; CAD: carotid artery dissection; CCAD: cranio-cervical artery dissection; CRP: C-reactive protein; CT: computed tomography; CTA: computed tomography angiography; dsDNA: double-stranded DNA; ESR: erythrocyte sedimentation rate; ICA: internal carotid artery; LA: lupus anticoagulant; MCA: middle cerebral artery; MRA: magnetic resonance angiography; MRI: magnetic resonance imaging; MTHFR: methylenetetrahydrofolate reductase; PT INR: prothrombin time international normalised ratio.

Pediatric emergency revisits of children with COVID-19.

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.

COVID-19 Disease in Presenting to the Pediatric Emergency Department: A Multicenter Study of 8886 Cases.

BACKGROUND: The aim was to evaluate the epidemiological, clinical, laboratory, and radiologic data of children with SARS-CoV-2 positivity by polymerase chain reaction (PCR) together with treatment strategies and clinical outcomes and to evaluate cases of multisystem inflammatory syndrome in children (MIS-C) in this population. METHODS: This was a multicenter retrospective observational cohort study performed in the pediatric emergency departments of 19 tertiary hospitals. From March 11, 2020, to May 31, 2021, children who were diagnosed with confirmed nasopharyngeal/tracheal specimen SARS-CoV-2 PCR positivity or positivity for serum-specific antibodies against SARS-CoV-2 were included. Demographics, presence of chronic illness, symptoms, history of contact with SARS-CoV-2 PCR-positive individuals, laboratory and radiologic investigations, clinical severity, hospital admissions, and prognosis were recorded. RESULTS: A total of 8886 cases were included. While 8799 (99.0%) cases resulted in a diagnosis of SARS-CoV-2 with PCR positivity, 87 (1.0%) patients were diagnosed with MIS-C. Among SARS-CoV-2 PCR-positive patients, 51.0% were male and 8.5% had chronic illnesses. The median age was 11.6 years (IQR: 5.0-15.4) and 737 (8.4%) patients were aged <1 year. Of the patients, 15.5% were asymptomatic. The most common symptoms were fever (48.5%) and cough (30.7%) for all age groups. There was a decrease in the rate of fever as age increased (p < 0.001); the most common age group for this symptom was <1 year with the rate of 69.6%. There was known contact with a SARS-CoV-2 PCR-positive individual in 67.3% of the cases, with household contacts in 71.3% of those cases. In terms of clinical severity, 83 (0.9%) patients were in the severe-critical group. There was hospital admission in 1269 (14.4%) cases, with 106 (1.2%) of those patients being admitted to the pediatric intensive care unit (PICU). Among patients with MIS-C, 60.9% were male and the median age was 6.4 years (IQR: 3.9-10.4). Twelve (13.7%) patients presented with shock. There was hospital admission in 89.7% of these cases, with 29.9% of the patients with MIS-C being admitted to the PICU. CONCLUSION: Most SARS-CoV-2 PCR-positive patients presented with a mild clinical course. Although rare, MIS-C emerges as a serious consequence with frequent PICU admission. Further understanding of the characteristics of COVID-19 disease could provide insights and guide the development of therapeutic strategies for target groups.

The Impact of Childhood and Parental Vaccination on SARS-CoV-2 Infection Rates in Children.

BACKGROUND: The data on the indirect protection of children via the coronavirus disease 2019 (COVID-19) vaccination of household members are insufficient, and analyses to evaluate the efficacy of COVID-19 vaccines are limited. METHODS: We gathered data on 12,442 patients under the age of 18 regarding the vaccination status of their household members, their vaccine preferences and doses, and their previous history of COVID-19 infection immediately before the patients were administered a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between September 1, 2021 and December 5, 2021. RESULTS: A total of 18.4% (2289) were vaccinated, 91.4% with BNT162b2mRNA vaccine, 8.6% with inactivated COVID-19 vaccine; 48.7% received a single dose, and 51.3% had 2 doses. Real-time RT-PCR positivity proportions were much higher in older children ( P < 0.001) and were higher in children 12 years of age and older [odds ratio (OR), 1.34; 95% confidence interval (CI): 1.21-1.47] compared with others. SARS-CoV-2 infection was significantly lower in the vaccinated group (fully and incompletely) ( P < 0.001). Unvaccinated (OR, 4.88; 95% CI: 3.77-6.13) and incompletely vaccinated children (OR, 1.83; 95% CI: 1.52-2.12) had a higher risk of COVID-19 infection compared with fully vaccinated patients No significant association was found between the COVID-19 real-time RT-PCR positivity rates of patients and the vaccination status or vaccine preferences of household members ( P > 0.05 each). CONCLUSIONS: SARS-CoV-2 infection rates were significantly lower in vaccinated children, especially with mRNA vaccines. The indirect protection of unvaccinated children via the vaccination of household members against COVID-19 seems inadequate. The individual vaccination of children remains crucial.

Evaluation of Suspected COVID-19 Patients in a Pediatric Emergency Department.

Coronavirus disease 2019 (COVID-19) is now a global pandemic. The aim of this study was to investigate the prevalence of COVID-19 in pediatric patients and to compare the characteristics of positive and negative patients. This study conducted from March to May 2020 in a tertiary children's hospital. Patients were included if they were under 18 years old and a SARS-CoV-2 polymerase chain reaction test had been performed. Of the 1,812 patients included in the study, 365 (20.1%) were positive for COVID-19. The median age was 102 months in the positive group, 70 months in the negative group ( p < 0.001). The sex distribution was almost equal. Nearly all positive patients had been in close contact with a COVID-19 infected family household member ( p < 0.001). The most common symptoms were fever (54.4%) and cough (38.6%). The asymptomatic patient rate was higher in the positive group ( p < 0.001). Lymphopenia (<1500/mm 3 ) was found in 29.9% of the positive children ( p = 0.005). When the groups were compared, white blood cell, neutrophil, lymphocyte, and platelet counts; neutrophil-to-lymphocyte ratio; and C-reactive protein level were lower in the positive group. Chest radiography was performed in 95.3% of the positive patients, and the results of 29.7% of them were interpreted as pathological ( p < 0.001). Most of the pediatric patients had a history of contact with COVID-19 positive individuals, and therefore, the diagnosis is generally suspected from a history of household exposure to COVID-19. Lymphopenia can help predict positivity. Awareness, reinforcing infection control measures, and performing health management within families are important steps to manage these patients.

Anaphylactic shock following minor abdominal trauma as the initial presentation of Echinococcus cyst: a case report.

BACKGROUND: Anaphylaxis is a potentially life-threatening condition caused by a variety of triggers. However, anaphylaxis following an abdominal trauma is an exceptionally rare condition and could be the first and only sign of hepatic hydatid cyst, especially when no obvious etiology is present. Here, we present such a rare case and discuss relevant diagnostic and management strategy in light of the literature. CASE REPORT: This case report refers to a 17 year-old previously healthy girl admitted in our pediatric emergency department (ED) for syncope after a minor blunt abdominal trauma. She was hypotensive on admission and shortly after she developed urticaria and angioedema. She was diagnosed with anaphylaxis and treated immediately. Possible etiologies including drug or food ingestion, insect bite, and previous allergy/anaphylaxis history were excluded. After stabilization abdominal imaging was performed, which revealed a ruptured large hepatic hydatid cyst in the vicinity of biliary tree. Albendazole treatment was started and surgical resection was performed after clinical stabilization, which confirmed the cyst rupture into the biliary ducts. Patient recovered without complications after surgery and was discharged uneventfully. CONCLUSION: This case report highlights that hydatid cyst rupture should be included in the differential diagnosis of anaphylaxis without obvious etiology, particularly in regions where hydatid disease is endemic. Ruptured hydatid cyst leading to anaphylaxis requires timely diagnosis, management and emergent intervention.

Evaluation of Unscheduled Return Visits to the Pediatric Emergency Department and Risk Factors for Admission After Return Visit.

OBJECTIVE: Unscheduled return visits to the emergency department (unscheduled RTED) increase both the workload and overcrowding in the emergency department. The aim in the present study is to identify the patient groups that require more careful and closer follow-up to reduce the rates of unscheduled RTED and hospital admissions after a return visit. METHODS: Among the patients admitted to the emergency department of our hospital between 2016 and 2017, those who made an unscheduled RTED within 72 hours after their first visit to the emergency department were evaluated retrospectively. RESULTS: Of the 137,787 eligible children, 3294 (2.8%) made unscheduled RTEDs within 72 hours. The median age was 28 months, and 1848 (57.6%) were male patients. The admission rate at the return visit was significantly higher among children younger than 2 years, in the patients presenting with respiratory complaints and severe acute conditions, and in those who presented to the emergency department for the first time during the department's busiest hours. The risk of admission upon a return visit to the emergency department was 2.7 times higher in the male sex, 5.4 times higher in children younger than 2 years, 5.9 times higher in patients with respiratory complaints, 4.9 times higher in patients with gastrointestinal tract complaints, and 27,000 times higher in patients with severe acute conditions. CONCLUSIONS: Unscheduled RTED and hospitalization rates can be reduced with more careful evaluation of young children, patients with respiratory and gastrointestinal complaints and those who apply during emergency department busiest hours.

The skills of defibrillation practice and certified life-support training in the healthcare providers in Turkey.

AIM OF THE STUDY: Successful cardiopulmonary resuscitation and early defibrillation are critical in survival after in- or out-of-hospital cardiopulmonary arrest. The scope of this multi-centre study is to (a) assess skills of paediatric healthcare providers (HCPs) concerning two domains: (1) recognising rhythm abnormalities and (2) the use of defibrillator devices, and (b) to evaluate the impact of certified basic-life-support (BLS) and advanced-life-support (ALS) training to offer solutions for quality of improvement in several paediatric emergency cares and intensive care settings of Turkey. METHODS: This cross-sectional and multi-centre survey study included several paediatric emergency care and intensive care settings from different regions of Turkey. RESULTS: A total of 716 HCPs participated in the study (physicians: 69.4%, healthcare staff: 30.6%). The median age was 29 (27-33) years. Certified BLS-ALS training was received in 61% (n = 303/497) of the physicians and 45.2% (n = 99/219) of the non-physician healthcare staff (P < .001). The length of professional experience had favourable outcome towards an increased self-confidence in the physicians (P < .01, P < .001). Both physicians and non-physician healthcare staff improved their theoretical knowledge in the practice of synchronised cardioversion defibrillation (P < .001, P < .001). Non-certified healthcare providers were less likely to manage the initial doses of synchronised cardioversion and defibrillation: the correct responses remained at 32.5% and 9.2% for synchronised cardioversion and 44.8% and 16.7% for defibrillation in the physicians and healthcare staff, respectively. The indications for defibrillation were correctly answered in the physicians who had acquired a certificate of BLS-ALS training (P = .047, P = .003). CONCLUSIONS: The professional experience is significant in the correct use of a defibrillator and related procedures. Given the importance of early defibrillation in survival, the importance and proper use of defibrillators should be emphasised in Certified BLS-ALS programmes. Certified BLS-ALS programmes increase the level of knowledge and self-confidence towards synchronised cardioversion-defibrillation procedures.

Sudden-onset haemolacria in an adolescent girl.

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.

The Burden of Burnout Syndrome in Pediatric Intensive Care Unit and Pediatric Emergency Department: A Multicenter Evaluation.

OBJECTIVE: The objective of this study was to detect variables associated with burnout syndrome (BS) in pediatric intensive care units (PICUs) and pediatric emergency medicine departments (PEDs) in high-volume centers from different parts of Turkey. METHODS: An observational, cross-sectional multicenter study was performed. The Maslach Burnout Inventory scale was administered to all of health care providers working in PICUs and PEDs. In this study, health care providers were defined as physicians, nurses, and other staff (secretaries, cleaning and patient care staff) working in PICU and PEDs. RESULTS: A total of 570 participants completed the survey. The major finding of this study was that 76.1% (n = 434) of PICU and PED health care professionals had BS. The most prominent subscale of BS was emotional exhaustion (62.5%). The rate of BS was higher among health care providers working in PEDs compared with PICUs (79.1% vs 73.7%, P = 0.04). The frequency of BS according to emotional exhaustion and depersonalization subscales was higher in health care providers of PEDs. The rate of BS was also significantly higher in younger employees, females, those working 51 or more hours totally in a week, those having a low monthly salary, those single or divorced, those without children, those with no childcare at home, those not owning a home, those not doing regular exercise and not having regular breakfast, those with total employment time of less than 1 year, and those not having a car or not having a hobby. In PEDs, when the daily evaluated number of patients was equal to or more than 44 (sensitivity, 88%; specificity, 66%), it predicted the occurrence of BS. In PICUs, when the number of patients cared for by 1 nurse was equal to or more than 3, it predicted the occurrence of BS (sensitivity, 78%; specificity, 62%). CONCLUSIONS: By creating early intervention programs to prevent BS, shortages of health care professionals can be avoided and the costs of health care expenditures related to infections can be decreased.

Mother-child interaction and the development status of children who have been accidentally poisoned.

Positive parent-child interaction, in particular bond between mother and child, is important for the mental and behavioral development of children. The aim of this study was to evaluate both mother-child interactions as well as the developmental status of children admitted to the pediatric emergency department with accidental poisoning using Parenting Interactions with Children: Checklist of Observations Linked to Outcomes tool (PICCOLO) and Denver Developmental Screening Test-II (DDST-II). Children between ages 1 to 5 years who were admitted to the emergency department with accidental poisoning were included in the study alongside a control group selected from healthy volunteers. A ten-minute video recording was obtained both for the case and control groups, while the mother and her child played together in a separate room. The interaction of mother-infant pair was assessed using the PICCOLO tool. The children`s development was examined using the DDST-II. The video recordings of 115 children (n=65 in the case group and n=50 in the control group) were evaluated. A high score of PICCOLO-teaching domain (≥9 points) was associated with a 3.3-fold increase in terms of risk of poisoning [p < 0.05, at 95% confidence interval (CI) of 1.34-8.37]. Multivariable analysis revealed that the PICCOLO-teaching domain was a significant factor. A high proportion of cases had either abnormal or questionable DDST-II scores (p < 0.05). In order to improve the bond between mother and child, drug poisoning prevention training must be meticulously provided to both mothers and children alike. Developmental assessments of these children as a holistic approach also should not be forgotten.

How Important Are Parental Age and Educational Level in Nonurgent Admissions to the Pediatric Emergency Department?

OBJECTIVE: The aims of the present study were to investigate the reasons parents prefer the pediatric emergency department for nonurgent admissions and to evaluate the effect of parental age and educational level on nonurgent admissions and the relationship between the reasons for nonurgent admissions and child age. METHODS: We conducted a cross-sectional survey at an emergency department of a tertiary care pediatric referral center. A questionnaire that was prepared to understand the reasons underlying nonurgent admissions was administered to the parents of 1033 children who were classified as nonurgent cases using the Pediatric Canadian Triage and Acuity Scale (4-5). RESULTS: The most common reasons for nonurgent admissions were the concern for progression in child's complaints, the complaints with an onset outside working hours, and the parental perception that more cautious and better care is provided in the emergency department. The most urgent complaints from the parental perspective included fever (23.1%), vomiting (11.0%), and diarrhea (10.5%), respectively. The mean age of the mothers was 31.1 ± 5.9 years (17-51 years), and the mean age of the fathers was 34.94 ± 6.1 years (20-60 years). Parents younger than 30 years were more likely to prefer the emergency department due to convenience and economic reasons. Nonurgent admissions due to confidence in the emergency department were more frequent among parents who were primary school graduate. CONCLUSIONS: It is critically important to examine why parents prefer the emergency department for nonurgent conditions of their children and to develop solution offers in this regard. The improvements to be made in the emergency department would both prioritize patients requiring urgent care and increase the productivity of emergency department staff.

Pediatricians' Attitude in Management of Acute Bronchiolitis: Did Guidelines Overcome Practices?

Background: Acute bronchiolitis is one of the most common diseases of early childhood. There are many recent changes in the treatment of acute bronchiolitis. The aim of this study is to evaluate treatment approaches to acute bronchiolitis among clinicians and to observe compliance with clinical guidelines. Materials and Methods: Our study was designed as a multicenter cross-sectional descriptive study. A cohort of pediatric residents, fellows, and attendants were surveyed with a questionnaire including general and occupational characteristics of pediatricians and treatment choices in acute bronchiolitis. Results: A total of 713 questionnaires were collected. Most commonly applied treatment among pediatricians was inhaled salbutamol, followed by intravenous hydration, hypertonic saline, and inhaled steroid. Most commonly preferred treatment in the management of mild bronchiolitis was oral hydration and inhaled salbutamol in severe bronchiolitis. Conclusion: Although recent guidelines for the treatment of acute bronchiolitis does not support the use of many different therapies, pediatricians still tend to use them, especially bronchodilators, corticosteroids, and antibiotics.

Outcome of out-of-hospital cardiopulmonary arrest in children: A multicenter cohort study.

Kurt F, Kendirli T, Gündüz RC, Kesici S, Akça H, Sahin S, Kalkan G, Derbent M, Tuygun N, Ödek Ç, Gültekin-Keser A, Oguz S, Polat E, Derinöz O, Tekin D, Teksam Ö, Bayrakci B, Suskan E. Outcome of out-of-hospital cardiopulmonary arrest in children: A multicenter cohort study. Turk J Pediatr 2018; 60: 488-496. The aim of this study was to evaluate the demographic characteristics of children who experienced out-of-hospital cardiopulmonary arrest (CPA), and to assess the impact of the bystander cardiopulmonary resuscitation (CPR) on the survival rate of witnessed arrests and the effects of the arrest and CPR durations on the neurological outcomes. This multicenter, retrospective study included a total of 182 patients who underwent CPR for out-of-hospital CPA between January 2008 and December 2012 at six centers in Ankara, Turkey. The median [interquartile range (IQR)] age was 22 (5-54) months; 60.4% of the patients were males, and 44% were younger than one year of age. The witnessed arrest rate was 75.8% (138/182) and the rate of bystander CPR was 13.9% (13/93). In these patients the rate of the return of spontaneous circulation (ROSC) was higher (76.9%). Following resuscitation in the patients for whom the spontaneous circulation was able to be returned, the median (IQR) duration of arrest was 5 (1- 15) min, while it was 15 (5-40) min for the remaining patients (p < 0.001). The ROSC rate was 94.9% in patients who underwent CPR for less than 20 min and 22% in patients requiring CPR longer than 20 min (p < 0.001). Survival to hospital discharge was 14.3%. Of these patients, 57.7% experienced neurological disability. The short duration of an arrest and the presence of CPR are both critical for survival. We suggest that a witness to the CPA, performing early and efficient CPR, yields better results.

Does age affect presenting symptoms in children with carbon monoxide poisoning?

OBJECTIVE: Previous studies have reported on a link between carboxyhemoglobin (COHb) levels and the severity of presenting findings. However, studies on pediatric populations evaluating the effect of age on presenting symptoms are severely lacking. The aim of this study was to investigate the presence of any link between age and presenting symptoms in children with carbon monoxide (CO) poisoning. METHODS: This retrospective study was undertaken in Ankara Children's Hematology and Oncology Hospital, a tertiary care center, between January 2007 and March 2010. The medical records of patients aged between 0 and 16 years with a confirmed diagnosis of CO poisoning, defined as the presence of a COHb level of more than 5%, were evaluated. Relevant information such as age, sex, source of CO, coaffected family members, month of presentation, time of presentation and presenting symptoms, duration of oxygen treatment in the emergency department, need for admission to an inpatient ward or intensive care unit, Glasgow Coma Scale scores, and administered treatments during follow-up was recorded for each patient on preprepared forms. For the purpose of comparison, patients were divided into 2 groups based on COHb levels (group 1, 5%-25%; group 2, >25%). Comparisons were also made after dividing patients into 3 age groups: infants (0-3 years), preschool and early-school children (4-8 years), and adolescents (9-16 years). RESULTS: The records of 261 patients were deemed sufficient for inclusion in the final analysis, 149 (57.1%) of which were female, and 112 (42.9%) were male, with a median age of 7.0 years (range, 1 month to 16 years) and a mean COHb level 16.9% (SD, 7.8%). Two hundred eighteen patients (83.5%) had a COHb between 5% and 25% on presentation, whereas the remaining 43 patients (16.5%) had a presenting COHb of greater than 25%. Neurologic symptoms such as headache, syncope, seizures, and confusion were encountered more frequently in the COHb greater than 25% group compared with the group with 5% to 25% COHb levels, with adolescents having more severe symptoms than do younger patients. CONCLUSIONS: In this study, we managed to demonstrate the presence of more severe symptoms in patients with a COHb level of 25% or greater. Further analysis revealed that severe symptoms were more pronounced in adolescents and that the severity of symptoms increased with age.

Hydrogen peroxide solution ingestion caused brain death of a 3-year-old girl.

Hydrogen peroxide solutions are often used in daily life as a household disinfectant and in cosmetic products and are therefore a common source of intentional poisonings, especially for children. When ingested in small amounts, it may cause severe central nervous system damage as a result of arterial emboli like our case. The benefit of hyperbaric oxygen treatment in this situation is known, but the neurologic deficits of our case did not improve with this method and finally brain death occurred. This is may be related by the timing of treatment after the event. We would like to emphasize that every clinician must be aware of the dangers of hydrogen peroxide ingestion and hyperbaric oxygen treatment may be of benefit if it is performed immediately.
