What is the safe observation period for seizure recurrence in pediatric emergency departments?

BACKGROUND: Afebrile seizures are the common causes of emergency department (ED) admissions in childhood, and there is limited data on the observation period in emergency service follow-up of these patients in terms of seizure recurrence in the literature. This study aims to determine the seizure recurrence time in afebrile seizures and the risk factors that determine it. METHODS: Patients aged between 1 month and 18 years with afebrile seizures were included in the study. Seizure recurrence times, demographic data, diagnosis of epilepsy, use of antiseizure medications, Electroencephalography (EEG) and imaging results, structural abnormalities, hospitalizations, and treatments were recorded. RESULTS: The median age of 623 patients included in the study was 42 months (16.0-94.0 months) and 59.9% were male. Epilepsy was diagnosed in 372 (59.7%) of the patients. Short-acting benzodiazepine was administered in 249 of the cases. The mean observation time of the patients was 36 hours (24-98 hours). Electroencephalography (EEG) was applied in 437 (70.1%) of the patients and abnormality was detected in 53.5%. Seizure recurrence was observed in 149 patients (23.9%). The median time of seizure recurrence was 1.0 hour (0.5-4.0 hours). Eighty-six percent of the seizure recurrences (n = 129) occurred within the first six hours and 95.3% (n = 142) within the first 12 hours. Risk factors included a history of febrile seizures (p = 0.001, OR = 2.7), not receiving short-acting benzodiazepine therapy (p = 0.026, OR 1.7), previous structural abnormalities (p = 0.018, OR 1.8), and cluster seizures (p = 0.001, OR 6.7) for all patients and also EEG abnormalities in pediatric ED for first seizure (p = 0.012, OR 2.4). CONCLUSION: Patients with a history of febrile seizure, previous structural abnormalities, cluster seizures, EEG abnormalities in pediatric ED, and patients who didn't receive BZD treatment were at risk for seizure recurrence in the early period. Since most seizure recurrences occur within the first 6 hours, this period is the most critical time for recurrence risk.

A snapshot of pediatric inpatients and outpatients with COVID-19: a point prevalence study from Turkey.

This multi-center point prevalence study evaluated children who were diagnosed as having coronavirus disease 2019 (COVID-19). On February 2nd, 2022, inpatients and outpatients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were included in the study from 12 cities and 24 centers in Turkey. Of 8605 patients on February 2nd, 2022, in participating centers, 706 (8.2%) had COVID-19. The median age of the 706 patients was 92.50 months, 53.4% were female, and 76.7% were inpatients. The three most common symptoms of the patients with COVID-19 were fever (56.6%), cough (41.3%), and fatigue (27.5%). The three most common underlying chronic diseases (UCDs) were asthma (3.4%), neurologic disorders (3.3%), and obesity (2.6%). The SARS-CoV-2-related pneumoniae rate was 10.7%. The COVID-19 vaccination rate was 12.5% in all patients. Among patients aged over 12 years with access to the vaccine given by the Republic of Turkey Ministry of Health, the vaccination rate was 38.7%. Patients with UCDs presented with dyspnea and pneumoniae more frequently than those without UCDs (p < 0.001 for both). The rates of fever, diarrhea, and pneumoniae were higher in patients without COVID-19 vaccinations (p = 0.001, p = 0.012, and p = 0.027).  Conclusion: To lessen the effects of the disease, all eligible children should receive the COVID-19 vaccine. The illness may specifically endanger children with UCDs. What is Known: • Children with COVID-19 mainly present with fever and cough, as in adults. • COVID-19 may specifically threaten children with underlying chronic diseases. What is New: • Children with obesity have a higher vaccination rate against COVID-19 than children without obesity. • Among unvaccinated children, fever and pneumoniae might be seen at a higher ratio than among vaccinated children.

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.

Evaluation of Pediatric Maxillofacial Injury: Who Is Critical?

OBJECTIVE: Isolated facial injuries are less common among pediatric trauma patients. The literature has focused on, especially, fractures in facial injuries. There is a limited number of studies evaluating all facial injuries in childhood. The study aims to evaluate the clinical characteristics of maxillofacial injuries and to identify patients who require further intervention. METHODS: The data from pediatric patients with maxillofacial injury (<18 years) between January 2011 and December 2015 were collected. Demographic characteristics, trauma mechanisms, concomitant injuries, treatments, hospitalization, and follow-up results were recorded. RESULTS: The median age of the patients (N = 2926) was 5.0 years (2.0-10.0 years), and 63.1% were boys. Falls and motor vehicle accidents were the leading mechanism of injury. The most common injury types were lacerations (49.3%) and fractures (15.5%). One hundred thirty (0.4%) patients had concomitant injuries. Surgical treatment was performed in only 3.4% of the patients, and the mortality rate was 0.6%. Patients with concomitant injuries had more hospitalization rates, surgical treatment, and organ dysfunction. All patients who underwent cardiopulmonary resuscitation and resulted in mortality were in the concomitant injury group. CONCLUSIONS: Isolated facial injuries are unlikely to be life-threatening, and basic interventions are sufficient in most of the maxillofacial injuries. The primary issue in maxillofacial injuries is to recognize and manage concomitant injuries that can lead to organ dysfunction and mortality.

Which Device Is Favorable for Intubation Attempts of Pediatric Residents on Four Different Pediatric Airway Simulations?

OBJECTIVES: Endotracheal intubation is an essential skill for the pediatric airway management. Although direct laryngoscopy (DL) is the standard method, several videolaryngoscopes (VLs) have been recently enhanced as an alternative especially for difficult intubations. We aimed to compare McGrath MAC (McG) and Storz C-MAC PM (ST) VLs with DL in terms of intubation success rate, time to intubation (TTI), and duration of obtaining glottis view of intubation attempts performed by pediatric residents on different pediatric airway manikins. METHODS: The pediatric residents with no experience in videolaryngoscopy were included. After a brief demonstration, intubation attempts with 3 randomly handled different devices with 6 different blades were performed on a child manikin, an infant manikin, a Pierre-Robin sequence infant manikin, and a child manikin with cervical immobilization sequentially. RESULTS: Fifty pediatric residents were enrolled. The attempts of DL on child manikin and attempts of all devices on child with cervical immobilization simulation were completely successful. For the attempts on both infant manikin and Pierre-Robin sequence infant manikin, the success rate of McG was significantly lower than ST and DL (P = 0.011 and P = 0.001). In the child manikin, McG and ST had prolonged TTI compared with DL (P = 0.016 and P = 0.001). For the child with cervical immobilization simulation, TTI of DL was significantly shorter than McG and ST (P = 0.011 and P = 0.001). Time to intubation of McG was significantly longer than DL and ST for the attempts on both 2 infant manikins. The rate of Cormack-Lehane grade I glottis view was similar for the attempts on both 2 child airway simulations. For infant manikin and Pierre-Robin sequence infant simulation, the rate of Cormack-Lehane grade I of ST was higher than attempts of DL and McG. CONCLUSIONS: The attempts of pediatric residents on infant normal airway and Pierre-Robin sequence infant airway simulations resulted with enhanced glottis view by the utilization of Storz C-MAC PM, but both 2 VLs did not provide the improvement of intubation success rate and TTI compared with DL on these 4 different pediatric manikins. Further clinical studies of different VLs in different clinical courses are required for a reliable utilization in children.

Unexpected Diagnosis in an Adolescent With Bruises and Ecchymosis: Celiac Disease.

ABSTRACT: Acquired coagulopathy is a rare but challenging diagnosis for pediatric emergency physicians. Although the coagulopathy usually presents with mild skin and mucosal hemorrhages, it also can lead to life-threatening events. Thus, accurate interpretation of hints obtained from a detailed history, physical examination, and laboratory findings is essential for the prompt diagnosis and management. This case demonstrates an uncommon cause of coagulopathy; celiac disease that presented with spontaneous bruises and ecchymosis in an adolescent.

Integration of Physical Examination, Old and New Biomarkers, and Ultrasonography by Using Neural Networks for Pediatric Appendicitis.

OBJECTIVE: The objective of this study was to evaluate physical examinations, imaging, and laboratory analyses individually and combined using innovative statistical analysis methods for the accurate diagnosis of pediatric appendicitis. METHODS: Patients admitted to hospital with symptoms of abdominal pain whose pediatric appendicitis scores greater than 3 were included in the study. Clinical, radiologic, and laboratory findings and as a new biomarker calprotectin (CPT) concentrations were evaluated individually and combined using artificial neural networks (ANNs), which revealed latent relationships for a definitive diagnosis. RESULTS: Three hundred twenty patients were evaluated (190 appendicitis [43 perforated] vs 130 no appendicitis). The mean ± SD age was 11.3 ± 3.6 years and 63% were male. Pediatric appendicitis scores, white blood cell (WBC) count, absolute neutrophil count (ANC), C-reactive protein (CRP) level, procalcitonin (PCT) and CPT concentrations were higher in the appendicitis group; however, only WBC and ANC were higher in first 24 hours of pain. White blood cells and CRP were diagnostic markers in patients whose appendix could not be visualized using ultrasonography (US). On classic receiver operating characteristic (ROC) analysis, the areas under the curve (AUCs) were not strong enough for differential diagnosis (WBC, 0.73; ANC, 0.72; CRP, 0.65; PCT and CPT, 0.61). However, when the physical examination, US, and laboratory findings were analyzed in a multivariate model and the ROC analysis obtained from the variables with ANN, an ROC curve could be obtained with 0.91 AUC, 89.8% sensitivity, and 81.2% specificity. C-reactive protein and PCT were diagnostic for perforated appendicitis with 0.83 and 0.75 AUC on ROC. CONCLUSIONS: Although none of the biomarkers were sufficient for an accurate diagnosis of appendicitis individually, a combination of physical examination and laboratory and US was a good diagnostic tool for pediatric appendicitis.

High-mobility Group Box 1 Protein in Pediatric Trauma Patients With Acute Traumatic Coagulopathy or Disseminated Intravascular Coagulation.

OBJECTIVES: Trauma can induce the release of high-mobility group box 1 (HMGB1), which plays an important role in the activation of coagulation. In this study, we aimed to evaluate the role of HMGB1 in the early diagnosis of acute traumatic coagulopathy (ATC), disseminated intravascular coagulation, and clinical course. MATERIALS AND METHODS: One hundred pediatric trauma patients and 50 healthy controls were enrolled. Demographic data, physical examination results, trauma scores, International Society on Thrombosis and Hemostasis score, laboratory values, transfusion requirements, and needs for mechanical ventilation were recorded. Blood samples for HMGB1 were assessed by an enzyme-linked immunosorbent assay. RESULTS: Thirty-five patients had ATC and 3 patients had overt disseminated intravascular coagulation. In trauma patients, HMGB1 levels were statistically higher than those in the control group (P<0.001). There was a positive correlation between HMGB1 levels and D-dimer levels (r=0.589, P<0.001). ATC patients had higher plasma HMGB1 levels than those without ATC (P=0.008). High HMGB1 levels were associated with the duration of mechanical ventilation, need for intensive care unit observation, length of hospital stay, and mortality. CONCLUSION: This study showed the early increase of HMGB1 in pediatric trauma cases and demonstrated the significant association of high HMGB1 levels with the development of ATC, disseminated intravascular coagulation, trauma severity, clinical outcome, and mortality.

Is Ischemia-Modified Albumin a Reliable Marker in Accurate Diagnosis of Appendicitis in Children?

BACKGROUND: Acute appendicitis is one of the most common abdominal emergencies. Despite all improvements in diagnostic techniques, there are still ongoing problems as proper diagnosis, misdiagnosis and perforated appendicitis. The aim of this study is to demonstrate the clinical value of IMA in patients with appendicitis and to determine the accurate diagnosis of appendicitis in clinically suspected patients. METHODS: Pediatric patients with acute abdominal pain who had the Pediatric Appendicitis Score (PAS) ≥ 7 (n = 109) and a control group of 35 patients were included in this prospective case-control study. Patients were divided into two groups: patients with appendicitis (pathologically confirmed) (n = 78) and no appendicitis (n = 31). No appendicitis included observation patients and negative appendectomy. Serum samples were collected for routine laboratory parameters and IMA before surgery. RESULTS: Patients with appendicitis had significantly higher IMA levels than no appendicitis and control groups (p = 0.001 and p < 0.001; respectively). Moreover, patients with negative appendectomy had significantly lower IMA levels than patients with appendicitis (p = 0.009). IMA and PAS were used together, and in the ROC analysis, we obtained 0.81 AUC for PAS and 0.89 AUC for PAS and IMA. CONCLUSION: The current study indicated that IMA is a reliable marker for accurate diagnosis of appendicitis. The combination of IMA with PAS score has been shown to facilitate the diagnosis of appendicitis.

Pediatric emergency department visit characteristics of the patients on the ketogenic diet.

BACKGROUND: The ketogenic diet (KD) has been frequently used for the patients with drug-resistant epilepsy in recent years. The management of these patients in emergency departments (EDs) has some difficulties due to the special needs of KD. We aimed to determine the characteristics and the management of the patients on the KD in the pediatric ED setting. METHODS: Patients who were on the KD and admitted to the ED were included in the study. Demographic, clinical, and laboratory data of all patients were retrospectively reviewed and recorded. RESULTS: There were 105 emergency admissions of 27 patients. The median age of all patients was 55.0 (IQR: 29.0-91.0) months. The most common symptom was vomiting (43.8%). Four patients had upper gastrointestinal bleeding, and one patient had hyperammonemic acute hepatic failure while receiving KD. Of the patients, 41.9% had seizure-related ED admission. Infections were present in 41.9% of the ED visits. The frequency of status epilepticus was significantly lower in the patients who were on the KD for more than 6 months (p < 0.01). In 42.9% of all ED admissions, dextrose containing maintenance fluids was administered mistakenly; although ketosis rate was lower, no seizure was observed in this group. CONCLUSION: The patients on the KD can be admitted to EDs with intercurrent illnesses or adverse effects of the KD. For accurate management, emergency physicians must be aware of the common reasons for ED admission of these patients and the effects of the KD.

Pathogens in Pediatric Septic Arthritis: A Multi-Center Study in Turkiye (PEDSART Study).

OBJECTIVES: Septic arthritis (SA) is a serious bacterial infection that must be treated efficiently and timely. The large number of culture-negative cases makes local epidemiological data important. Accordingly, this study aimed to evaluate the etiology, clinical characteristics, and therapeutic approach of SA in children in Turkiye, emphasizing the role of real-time polymerase chain reaction (PCR) techniques in the diagnosis. METHODS: In this multi-center, prospective study, children hospitalized due to SA between February 2018 and July 2020 in 23 hospitals in 14 cities in Turkiye were included. Clinical, demographic, laboratory, and radiological findings were assessed, and real-time PCR was performed using synovial fluid samples. RESULTS: Seventy-five children aged between 3 and 204 months diagnosed with acute SA were enrolled. Joint pain was the main complaint at admission, and the most commonly involved joints were the knees in 58 patients (77.4%). The combination of synovial fluid culture and real-time PCR detected causative bacteria in 33 patients (44%). In 14 (18.7%) patients, the etiological agent was demonstrated using only PCR. The most commonly isolated etiologic agent was Staphylococcus aureus, which was detected in 22 (29.3%) patients, while Streptococcus pyogenes was found in 4 (5.3%) patients and Kingella kingae in 3 (4%) patients. Streptococcus pyogenes and Kingella kingae were detected using only PCR. Most patients (81.3%) received combination therapy with multiple agents, and the most commonly used combination was glycopeptides plus third-generation cephalosporin. CONCLUSIONS: Staphylococcus aureus is the main pathogen in pediatric SA, and with the use of advanced diagnostic approaches, such as real-time PCR, the chance of diagnosis increases, especially in cases due to Kingella kingae and Streptococcus pyogenes.

Clinical profile and etiologies of children with central diabetes insipidus: a single-center experience from Turkey.

AIM: The aim of this study is to evaluate the clinical, anthropometric, hormonal, and radiological characteristics of children with central diabetes insipidus (DI). METHODS: Case records of 34 children (22 boys and 12 girls) with documented central DI referred to the Pediatric Endocrinology and Adolescent Clinic of Dokuz Eylul University Faculty of Medicine were reviewed. The mean age at diagnosis was 6.4 +/- 5.6 years (range, 0.08-16 years). All patients underwent anterior pituitary function assessment and magnetic resonance imaging of pituitary at diagnosis. The median duration of follow-up was 7.9 +/- 4.5 years. RESULTS: The etiology of central DI was organic in 22 (64.7%) patients, trauma in 2 (5.9%) patients, and idiopathic in 10 (29.4%) patients. Organic causes consisted of craniopharyngioma in 7 patients, Langerhans cell histiocytosis in 4 patients, germinoma in 4 patients, holoprosencephaly in 3 patients, astrocytoma in 1 patient, cavernous hemangioma in 1 patient, Rathke's cleft cyst in 1 patient, and autoimmune polyendocrinopathy in 1 patient. Anterior pituitary hormone deficiencies were documented in 18 (53%) patients. Organic central DI group had a greater prevalence of anterior pituitary hormone deficiency when compared with the idiopathic group (66% and 10%, respectively; p = 0.007). The final height of patients with organic etiology were significantly lower than the idiopathic group (155 and 178, cm respectively; p = 0.021). CONCLUSIONS: Etiological diagnosis is possible in a significant proportion (70.6%) of children with central DI. Findings of this study suggest that accompanying anterior pituitary hormone deficiencies and short stature may be considered as indicators of organic etiology.

Determinants of mortality and intensive care requirement in pediatric thoracoabdominal injuries.

BACKGROUND: Thoracoabdominal injuries (TAI) are an important cause of trauma-related morbidity in children. Early and correct intervention is essential to reduce mortality. We aimed to determine factors associated with mortality and the need for intensive care in TAI. METHODS: The children admitted to the pediatric emergency department of a tertiary care hospital with TAI in a 6-year-period were enrolled. Demographic data; mechanism of injuries; clinical, laboratory and imaging findings; length of hospital and intensive care unit (ICU) stay; invasive procedures and medical treatments; surgical interventions; and survival outcomes were recorded. RESULTS: The median age of the 136 children was 9 (IQR: 5-14) years and 72.8% were male. The vast majority of injuries were caused by blunt trauma (92.7%). Pulmonary contusion, pneumothorax, splenic, and liver injuries were the most common diagnoses. Motor vehicle accidents were seen in more than half of the cases (52.2%). The median length of hospital stay was 5 (IQR: 2-8) days; 21 patients were hospitalized in the ICU (15.4%). The need for intensive care was higher in patients with lower Glasgow Coma Scale (GCS) scores and lower Pediatric Trauma Scores (PTSs), in the presence of multiple injuries, pulmonary contusion, and pneumothorax (p<0.001). Mortality was seen in nine patients, eight of whom had multiple injuries. The mortality rate was higher in patients with pulmonary contusion and pneumothorax (p=0.002 and p=0.003, respectively). The PTS and GCS were found to be lower in patients who died in hospital (p<0.001). Prolongation of coagulation parameters and hyperglycemia was more common in the non-survivor group (p=0.005 and p=0.004, respectively). CONCLUSION: Although thoracoabdominal trauma is not common in childhood, it is an important part of trauma-associated mortality. Multiple injuries, pulmonary contusion, pneumothorax, lower GCS, and PTSs can be a sign of serious injuries to which physicians must be alert.

The role of sonographic optic nerve sheath diameter measurements in pediatric head trauma.

PURPOSE: To determine the accuracy of bedside sonographic measurements of optic nerve sheath diameter (ONSD) and ONSD/eyeball transverse (ETD) diameter ratios to predict space-occupying lesions (SOLs) or elevated intracranial pressure (ICP) in pediatric head trauma. METHODS: Children who presented to the emergency department with head trauma and underwent cranial computed tomography (CT) were enrolled and examined by ocular ultrasonography (US), and the ONSD was measured at 3 mm posterior to the globe and ETD were measured. Ratios of ONSD at 3 mm/ETD were calculated. All ONSD measurements and ratios were calculated from cranial CT images. RESULTS: Subjects with elevated ICP had increased ONSD measurements and ratios. To predict elevated ICP, the AUC for ONSD at 3 mm was 0.956 (95% CI 0.896-1). At a cut-off level of 5.1 mm, the sensitivity and specificity of ONSD 3 mm values for elevated ICP were 92.9% and 94.0%. For the ONSD 3 mm/ETD ratio, it was 0.980 (95% CI 0.959-1). At a cut-off level of 0.22, the sensitivity and specificity were 100% sensitivity and 88.0%. All sonographic ONSD measurements and ratios were significantly correlated with readings calculated from cranial CT images. CONCLUSION: Sonographic ONSD measurements and ratios were found to be quite sensitive to detect elevated ICP on cranial CT images. Additionally, there was a significant correlation between measurements calculated by ocular US and cranial CT scans. Bedside ocular US seems to be a promising and useful tool to determine ICP in children with head trauma.

Are clinical features and cardiac biomarkers at admission related to severity in pediatric acute myocarditis?: Clinical features and cardiac biomarkers in pediatric acute myocarditis.

OBJECTIVES: To evaluate the factors associated with intensive care requirement and mortality in pediatric myocarditis. METHODS: Children aged 28 days to 18 years who were diagnosed with acute myocarditis in a pediatric emergency department between January 2010 and September 2020 were enrolled in the study retrospectively. Demographic and clinical features, cardiac biomarkers, and imaging findings were evaluated. Length of hospital stay, need for hospitalization in the pediatric intensive care unit (PICU), treatments, and survival outcomes were recorded. To define the severity of disease, three groups were created and the data were compared in terms of clinical, laboratory, and imaging findings. The patients treated in the pediatric ward were compared with those hospitalized in the PICU. Ventricular dysfunction was defined in patients with a left ventricular ejection fraction (LVEF) of <50% and these patients were compared with those who had an LVEF of >50%. Also, survivor and non-survivor patients were compared. RESULTS: A total number of 62 patients with a median age of 8 years were included. Chest pain and tachycardia were the most common findings on physical examination. The mean LVEF was 59.3 ± 13.0% at admission. Of the patients, 17 were hospitalized in the PICU (27.4%). Chest pain was more common in patients hospitalized in the pediatric ward (p<0.001), and hypotension, vomiting, arrhythmia, were more common and LVEF was lower in patients in the PICU (p = 0.017, p = 0.008, p = 0.006, and p = 0.025, respectively). The children treated in the PICU were younger than those in the pediatric ward (p = 0.009). Troponin I levels were significantly higher in the pediatric ward (p = 0.035), and brain natriuretic peptide (BNP) levels were higher in patients in the PICU (p = 0.012). Death occurred in four patients. Hypotension and vomiting were significantly more common in non-survivors (p = 0.020 and 0.004, respectively). Inotropes and intravenous immunoglobulin (IVIG) were more commonly used in non-survivors (p = 0.001 and p = 0.015, respectively). BNP levels were higher in non-survivors (p = 0.008), and troponin I levels were not different between survivors and non-survivors (p = 0.260). CONCLUSION: In pediatric acute myocarditis, lower LVEF, increased BNP, as well as the presence of hypotension and arrhythmia were found to be related to intensive care requirement. Hypotension and vomiting were found to be more common in non-survivors. Due to the possibility of rapidly worsening disease, physicians should be alert to the presence of these findings.

Serum motilin levels and motilin gene polymorphisms in children with functional constipation.

BACKGROUND: Functional constipation is an important clinical problem among chidren all over the world. Its main cause is not completely understood. Motilin is a gastrointestinal hormone that increases intestinal motility. In this study, we aimed to investigate the serum motilin levels and its relationship with stool consistency and motilin gene polymorphisms in constipated children. METHODS: In this study we investigated 91 constipated patients (mean age 6.84±3.55 years) and 100 healthy controls (mean age 7.78±4.25 years). Serum motilin levels were assessed by sandwich enzyme-linked immunosorbent assay. rs2281820 (c.44 C>T) and rs2281818 (c.66 C>T) mutations were evaluated for motilin gene polymorphisms. RESULTS: Serum motilin levels were significantly lower in constipated children than healthy controls (6.20±7.86 vs. 11.54±17.89 pg/mL, respectively, P=0.008). Serum motilin levels were significantly correlated with Bristol stool scale rate (r=0.193, P=0.011) in whole study group, but in the constipation group there was no significant correlation (r=-0.072, P=0.528). There were no differences in terms of presence or distribution of the polymorphisms of rs2281820 (c.44 C>T) and rs2281818 (c.66 C>T) in both groups. There was not a significant difference between different polymorphism groups regarding serum motilin concentrations in whole study group and also in both of the study groups. CONCLUSIONS: This study indicated for the first time that serum motilin levels decreased in constipated children. Further studies are needed to clarify whether motilin or motilin gene polymorphisms has a role in pathogenesis of functional constipation.

Multicenter Hospital-Based Prospective Surveillance Study of Bacterial Agents Causing Meningitis and Seroprevalence of Different Serogroups of Neisseria meningitidis, Haemophilus influenzae Type b, and Streptococcus pneumoniae during 2015 to 2018 in Turkey.

The etiology of bacterial meningitis in Turkey changed after the implementation of conjugated vaccines against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) in the Turkish National Immunization Program (NIP). Administration of Hib vaccine and PCV-7 (7-valent pneumococcal conjugate vaccine) was implemented in NIP in 2006 and 2009, respectively. In 2011, PCV-7 was replaced with PCV-13. Meningococcal vaccines have not yet been included in Turkish NIP. This prospective study comprised 27 hospitals located in seven regions of Turkey and represented 45% of the population. Children aged between 1 month and 18 years who were hospitalized with suspected meningitis were included. Cerebrospinal fluid (CSF) samples were collected, and bacterial identification was made according to the multiplex PCR assay results. During the study period, 994 children were hospitalized for suspected meningitis, and Hib (n = 3, 2.4%), S. pneumoniae (n = 33, 26.4%), and Neisseria meningitidis (n = 89, 71%) were detected in 125 samples. The most common meningococcal serogroup was MenB. Serogroup W comprised 13.9% (n = 5) and 7.5% (n = 4) of the meningococci in 2015 to 2016 and 2017 to 2018, respectively. Serogroup C was not detected. There were four deaths in the study; one was a pneumococcus case, and the others were serogroup B meningococcus cases. The epidemiology of meningococcal diseases has varied over time in Turkey. Differing from the previous surveillance periods, MenB was the most common serogroup in the 2015-to-2018 period. Meningococcal epidemiology is so dynamic that, for vaccination policies, close monitoring is crucial.IMPORTANCE Acute bacterial meningitis (ABM) is one of the most common life-threatening infections in children. The incidence and prevalence of ABM vary both geographically and temporally; therefore, surveillance systems are necessary to determine the accurate burden of ABM. The Turkish Meningitis Surveillance Group has been performing a hospital-based meningitis surveillance study since 2005 across several regions in Turkey. Meningococcus was the major ABM-causing agent during the 2015-to-2018 period, during which MenB was the dominant serogroup.

Levels of Soluble Urokinase Plasminogen Activator Receptor in Pediatric Lower Respiratory Tract Infections.

Background: Lower respiratory tract infections (LTRIs) are the most common cause of pediatric emergency department visits and are associated with significant morbidity and mortality. The aim of this study was to evaluate the soluble urokinase plasminogen activator receptor (suPAR) levels in pediatric patients with LRTIs and to investigate the correlation of suPAR with disease severity. Methods: This is a prospective case-control study of children with LTRIs. Demographic data, diagnoses, vital signs, disease severity scores, length of hospital stay, laboratory findings, and viral polymerase chain reaction results for nasopharyngeal aspirates were recorded. Blood samples for suPAR were collected and assessed by enzyme-linked immunosorbent assay. Results: There were 94 patients with LTRIs and 32 children in the control group. Patients were further subdivided into 2 groups based on diagnosis of acute bronchiolitis (n: 31, 33%) or pneumonia (n: 63, 67%). The median levels of suPAR were significantly higher in patients with LTRIs than in healthy controls (4.3 and 3.5 ng/mL, respectively; P = 0.003). There was an association between suPAR levels and disease severity in pneumonia patients. suPAR values were higher in patients with severe pneumonia than mild pneumonia (5.5 and 3.6 ng/mL, respectively; P < 0.001). Conclusion: We have shown that suPAR levels increased in patients with LTRIs and suPAR values were higher in patients with severe pneumonia than mild pneumonia. Further studies with large case series are needed to clarify the role of suPAR levels in children with LTRIs.

The effect of early midazolam infusion on the duration of pediatric status epilepticus patients.

PURPOSE: Status epilepticus is one of the most common neurological emergencies in pediatric emergency departments. Although there are different approaches to treatment in the literature, early control of seizure activity is the most important factor determining prognosis. The purpose of this study was to evaluate the effect of early midazolam infusion on seizure duration. METHOD: This retrospective study included 150 episodes of 135 patients aged one month to 18 years old with status epilepticus. All patients were treated according to the local hospital protocol for SE, which included early midazolam infusion. Demographic data, medical history, applied treatments during SE, and seizure durations were recorded. RESULTS: The median age of the patients (58.7% male) was 2.7 years (1.0-6.0 years). The most common identified etiologies were remote symptomatic etiologies, and generalized tonic-clonic seizure was the most common seizure type. The pediatricians had selected intravenous midazolam for 130 patients (86.7%) as the first-line therapy in emergency services. In 55 patients given continuous midazolam infusion, the cumulative bolus of midazolam was 0.5 mg/kg (0.4-0.7 mg/kg), and the median peak rate of midazolam infusion was 0.2 mg/kg/h (0.2-0.4 mg/kg/h). The median duration between the start of midazolam infusion and the complete cessation of SE was 15.0 min (9.0-25.0 min). The early-midazolam infusion group had shorter seizure duration after initiation of midazolam infusion (p = 0.020). CONCLUSION: The current study shows that aggressive management of SE with early initiation of midazolam infusion was associated with a shorter seizure duration in SE patients.

Elevated serum neopterin levels in children with functional constipation: association with systemic proinflammatory cytokines.

BACKGROUND: Functional constipation is a clinical problem with an incompletely understood etiology. Functional bowel diseases have been shown to be related to inflammation in many studies in adults. In this study, we aimed to evaluate leukocytes, C-reactive protein, proinflammatory and anti-inflammatory cytokines, and neopterin levels in children with functional constipation. METHODS: Seventy-six children with constipation and 71 healthy controls (mean age 7.12 ± 3.46 years and 7.32 ± 4.33 years, respectively, P = 0.991) were included in the study. Leukocytes, C-reactive protein, interleukin (IL)-1ß, IL-6, IL-10, IL-12, tumor necrosis factor-alpha (TNF-α) and neopterin levels were assessed in patients and healthy controls. Parameters were measured in the serum using enzyme-linked immunosorbent assay methods. RESULTS: Mean IL-6 (20.31 ± 12.05 vs. 16.2 ± 10.25 pg/mL, respectively, P = 0.003), IL-12 (181.42 ± 133.45 vs. 135.6 ± 83.67 pg/mL, respectively, P = 0.018) and neopterin levels (2.08 ± 1.12 vs. 1.52 ± 1.02 pg/mL, respectively, P = 0.001) were significantly higher in constipated children than healthy controls. Leukocyte and thrombocyte counts, C-reactive protein, and IL-1ß, IL-10 and TNF-α levels did not show any difference between the two groups. CONCLUSIONS: In this study, IL-6, IL-12 and neopterin levels of constipated patients were found to be higher than those of controls. These results indicate the presence of subclinical inflammation in children with functional constipation.
