A Retrospective Cohort Study of Traumatic Brain Injury in Children: A Single-Institution Experience and Determinants of Neurologic Outcome.

Introduction: Traumatic brain injury (TBI) has become a significant cause of death and morbidity in childhood since the elucidation of infectious causes within the last century. Mortality rates in this population decreased over time due to developments in technology and effective treatment modalities. Aim of the study: This retrospective cohort study aimed to describe the volume, severity and mechanism of all hospital-admitted pediatric TBI patients at a university hospital over a 5-year period. Material and Methods: This was a single-center, retrospective cohort study including 90 pediatric patients with TBI admitted to a tertiary care PICU. The patients' demographic data, injury mechanisms, disease and trauma severity scores, initiation of enteral nutrition and outcome measures such as hospital stay, PICU stay, duration of mechanical ventilation, mortality, and Glasgow Outcome Scale (GOS) were also recorded. Late enteral nutrition was defined as initiation of enteral feeding after 48 hours of hospitalization. Results: Of the 90 patients included in the cohort, 60% had mild TBI, 21.1% had moderate TBI and 18.9% had severe TBI. Their mean age was 69 months (3-210 months). TBI was isolated in 34 (37.8%) patients and observed as a part of multisystemic trauma in 56 (62.2%). The most commonly involved site in multisystemic injury was the thorax (33.3%). The length of hospitalization in the late enteral nutrition group was significantly higher than that in the early nutrition group, while the PICU stay was not significantly different between the two groups. The multiple logistic regression analysis found a significant relationship between GOS-3rd month and PIM3 score, the presence of diffuse axonal injury and the need for CPR in the first 24 h of hospitalization. Conclusion: Although our study showed that delayed enteral nutrition did not affect neurologic outcome, it may lead to prolonged hospitalization and increased hospital costs. High PIM3 scores and diffuse axonal injury are both associated with worse neurologic outcomes.

Factors predicting kidney replacement therapy in pediatric earthquake victims with crush syndrome in the first week following rescue.

Crush syndrome due to traumatic rhabdomyolysis is one of the most significant problems to occur following earthquakes. On February 6, 2023, millions of people in Turkey were affected by two consecutive Kahramanmaras earthquakes. The present study reports the analysis of clinical and laboratory findings of crush syndrome in pediatric earthquake victims admitted to our hospital from our region where the earthquake had a devastating effect. Clinical and laboratory findings concerning earthquake victims with crush syndrome were analyzed within the first week to determine what factors are predictive of kidney replacement therapy (KRT). The data of patients were retrospectively collected from medical records. A total of 310 children were admitted as earthquake victims to the pediatric emergency department. Ninety-seven (31%) of these patients had crush syndrome. Fifty-three (55%) of those with crush syndrome were female. The mean age was 10.9 ± 4.7 years, and the mean time under the rubble was 30.6 ± 23.8 h. Twenty-two patients (23%) required KRT. Hemodialysis was applied to 16 (73%) of them, and hemodiafiltration was applied to the other six (27%) in the pediatric intensive care unit. Regarding creatine kinase (CK) levels, the area under the receiver operating characteristic (ROC) curve (AUC) for predicting KRT was 0.905 (95% confidence interval [CI] 0.848-0.963; p < 0.001). The optimal cut-off value was 40,000 U/L with a sensitivity of 86% and a specificity of 83%. In terms of the percentage of body area crushed, the AUC for predicting KRT was 0.907 (95% CI 0.838-0.976; p < 0.001). The optimal cut-off value was 30% with a sensitivity of 86% and a specificity of 88%. Multiple logistic regression analysis showed that each 10% increase in body area crushed (OR 4.16, 95% CI 1.58-10.93, p = 0.004) and 1 mg/dl increase in the serum phosphorus level (OR 4.19, 95% CI 1.71-10.28, p = 0.002) were significant risk factors for dialysis treatment. CONCLUSIONS: Crush syndrome and kidney problems are common following disasters like earthquakes. Clinical and laboratory findings at admission can predict dialysis requirement in earthquake victims. While CK elevation, body area crushed percentage, and increased phosphorus level were predictive of dialysis treatment, time under the rubble was not. Even if the patients were under the rubble for a short time, acute kidney injury (AKI) may develop as a result of severe hypovolemia due to crush injuries, and patients may need KRT. WHAT IS KNOWN: •Crush syndrome after earthquakes needs to be treated carefully in victims and can cause AKI and mortality when not treated timely and appropriately. WHAT IS NEW: •CK level elevation, body area crushed percentage, and increased phosphorus level are predictive of dialysis treatment. •The time under the rubble may not be predictive of dialysis requirement.

Clinical characteristics of firearm-related injuries in children in Turkey.

BACKGROUND: A significant number of children are injured by or die from firearm-related incidents every year, although there is a lack of global data on the number of children admitted to pediatric emergency departments (PEDs) and pediatric intensive care units (PICU) with firearm injuries. This study is the most comprehensive analysis of firearm injuries sustained by children in Turkey to date. METHODS: This multicenter, retrospective, cohort study was conducted between 2010 and 2020 with the contributions of the PEDs, PICUs, intensive care units, and surgery departments of university hospitals and research hospitals. RESULTS: A total of 508 children were admitted to hospital with firearm-related injuries in the research period, although the medical records of only 489 could be obtained. Of the total admissions to hospitals, 55.0% were identified as unintentional, 8.2% as homicide, 4.5% as self-harm, and 32.3% as undetermined. The Glasgow Coma Scale (GCS) and ventilation support were found to be the most significant predictors of mortality, while head/neck injury, length of stay (LOS) in the hospital and surgical interventions were found to be the most significant predictors of disability. The overall mortality of firearm-related injuries was 6.3%, and the mortality for children admitted to the PICU was 19.8%. The probability of disability was calculated as 96.0% for children hospitalized with firearm injuries for longer than 75 days. CONCLUSIONS: Head/neck injury, LOS in the hospital, and surgical interventions were found to be the most significant parameters for the prediction of disability. Hospitalization exceeding 6 days was found to be related to disability.

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.

Characteristics and outcomes of critically ill children transported by ambulance in a Turkish prehospital system: a multicenter prospective cohort study.

BACKGROUND: The most underdeveloped area in the care of critically-ill-children (CIC) is the prehospital period. Appropriate prehospital assessment and life-saving-interventions (LSI) of this population are challenging and require dedicated resources to ensure the best outcomes. We aimed to determine the characteristics and outcomes of CIC transported to the Turkish Pediatric Emergency Departments (EDs). The frequency and distribution of LSI administered by prehospital providers on route and in the EDs were also investigated. METHODS: This prospective study was conducted at 4 metropolitan cities and 9 tertiary pediatric EDs between August 2014-August 2015. A survey based study evaluated all CIC who were brought by ambulance to the participant EDs. CIC were defined as a patient who requires LSI or needs intensive care admission for any reason. Patient demographics, clinical features, reason for transport, performed procedures in the ambulance or ED were sought. Finally, the short-term outcomes of transported CIC and transport-associated risks were analyzed. RESULTS: During the study period, a total 2094 children were brought by ambulance to all participant EDs. Only 227 (10.8%) of them were critically-ill. Emergency Medical Services (EMS) providers were less likely to perform procedures in CIC if they were staffed with paramedics (p < 0.001). Most procedures were performed on children aged one or older (p < 0.001). No procedure was performed in the ambulance for nearly one fourth of patients who received LSI in the EDs. If the EMS did not have a physician, prehospital providers were less likely to provide immediate LSIs (p < 0.001). CIC were more likely referred from secondary/tertiary care hospitals. The short-term mortality rate was higher if the ambulance was staffed by only paramedics. CONCLUSION: This study demonstrated that Turkish prehospital pediatric emergency care is deficient. We offer a clinical overview of pediatric emergencies to aid EMS directors, policymakers, and ED directors in planning the care of CIC.

Is there any relationship between initial hematological parameters and severity of scorpion envenomation?

BACKGROUND AND OBJECTIVES: Most cases of severe scorpion envenomation occur in children and are associated with significant morbidity and mortality. Excessive systemic inflammatory response, which leads to multiple organ involvement, is an emerging challenge during severe envenomation. The aim of this study was to investigate if there was any relationship between initial hematological parameters and severe envenomation in pediatric patients presenting with scorpion envenomation. METHOD: This study was performed retrospectively, at the pediatric emergency unit and pediatric intensive care unit of the Çukurova University Medical School in Turkey. Two hundred and fifty-seven cases with scorpion envenomation, and a control group consisting of one hundred and fifteen healthy children were included in the study. RESULTS: White blood cell, neutrophil, lymphocyte, platelet, neutrophil/lymphocyte ratio (NLR), platelet/ lymphocyte ratio (PLR) and PDW values of patients were higher than the controls (p < 0.05). Mean NLR was 3.8 ± 4.7 in patients. Patients were analyzed with the help of the decision tree model, and it was seen that in patients who had applied to hospital in less than an hour after the scorpion sting, 87.5% of the patients whose NLR value was between the 0.519-1.969 interval (below 2.1 which we found as the cut-off value) did not need to be hospitalized in the intensive care unit, 54.1% of the patients whose NLR value was higher than 1.969 needed to be hospitalized at the intensive care unit. CONCLUSIONS: Severe envenomation is associated with mortality and morbidity in children. Our findings showed that NLR seems to be a useful tool in predicting severe envenomation.

Lung Ultrasound Findings and Bronchiolitis Ultrasound Score for Predicting Hospital Admission in Children With Acute Bronchiolitis.

OBJECTIVES: The purposes of this study were to determine the benefit of the bronchiolitis ultrasound score (BUS) in predicting hospital admission in children with acute bronchiolitis and to characterize lung sonography findings. METHODS: This prospective observational study was performed in an academic pediatric emergency department. Children younger than 24 months presenting to the emergency department, diagnosed with acute bronchiolitis by 2 independent pediatricians were included in the study. Lung ultrasound was performed by a single sonographer, who was blinded to as much clinical information as possible. In addition, the treating physicians were blinded to the lung ultrasound findings. Logistic regression analysis models were used to identify admission predictors. Receiver operating characteristic analysis was used to evaluate the predictive value for effects of the BUS and the modified Bronchiolitis Severity Score on admission. RESULTS: The median age of the 76 patients diagnosed with acute bronchiolitis was 6 months (interquartile range, 3.6-10 months). Forty-two (55.3%) of the 76 patients enrolled were admitted. Lung ultrasound was compatible with acute bronchiolitis in 74 patients (97%). A significant correlation was determined between modified Bronchiolitis Severity Score and BUS in children with acute bronchiolitis (r = 0.698, P < 0.001). The most effective parameter in determining admission on logistic regression analysis, independently of other variables, was BUS (P = 0.044; adjusted odds ratio, 1.859; 95% confidence interval, 1.016-3.404). Bronchiolitis ultrasound score values of 3 or greater exhibited 73.81% sensitivity and 73.53% specificity, whereas BUS values of 4 or greater exhibited 50% sensitivity and 91.18% specificity. CONCLUSIONS: Point-of-care lung ultrasound can accurately detect pulmonary anomalies in children with acute bronchiolitis, has a close correlation with clinical findings, and is a useful tool in predicting hospital admission.

Determination of cerebral edema with serial measurement of optic nerve sheath diameter during treatment in children with diabetic ketoacidosis: a longitudinal study.

Background Cerebral edema is a fatal complication that can occur in children with diabetic ketoacidosis (DKA). Its clinical signs are generally not explicit, and subclinical cerebral edema can occur. This study is one of the few longitudinal studies conducted to identify cerebral edema in patients with DKA by measuring the optic nerve sheath diameter (ONSD). The aim of this study was to investigate cerebral edema in children with DKA with serial measurement of ONSD, which is an early and reliable indicator of cerebral edema, and to monitor changes in ONSD during therapy. Methods The study was conducted by measuring ONSD ultrasonographically at baseline and during the course of therapy in patients with DKA. All participants were diagnosed and received therapy at our unit between May 2016 and June 2017. The study was registered with the Clinical Trials database, with a study number of NCT02937441. Measurements were obtained while the patients were in the supine position with their eyes closed, and axial transbulbar images of both eyes were obtained with a 6-15-MHz linear probe. Results The ONSD values of children with DKA changed during the treatment, reaching the highest values at 12-16 h of therapy, and the greatest ONSD was observed in children who had moderate and severe DKA. Conclusions During treatment of children with DKA, it is possible to predict cerebral edema by measuring ONSD, and this may contribute to clinical management, especially fluid treatment.

Do practical laboratory indices predict the outcomes of children with Henoch-Schönlein purpura?

Objectives: Henoch Schönlein Purpura (HSP) is the most common systemic vasculitis of childhood and often has a self-limiting course. We aimed to study whether practical laboratory parameters at the diagnosis predict disease course including recurrence and nephritis in addition to severe gastrointestinal involvement in children with HSP. Methods: This retrospective cohort study included 214 HSP patients, 43.5% (n = 93) female and 56.5% (n =121) male, who were diagnosed in our department. Laboratory parameters before treatment, including neutrophil, lymphocyte and platelet counts, mean platelet volume (MPV), neutrophil-to-lymphocyte (NLR), and platelet-to-lymphocyte ratios (PLR) were obtained retrospectively. Age at diagnosis, duration of follow-up, gender, preceding infections, medications, arthritis and arthralgia, abdominal pain, severe GI involvement, invagination, renal involvement and presence of nephritis, outcomes, and presence of recurrences were retrospectively recorded from medical files. Severe GI involvement was determined as severe colicky abdominal pain, bowel edema in ultrasonography or overt GI bleeding. A relapse was defined as a new flare of cutaneous lesions or other manifestations in a patient at least four asymptomatic weeks after the initial HSP episode. Results: Mean age at diagnosis was 7.6 ± 3.1 years. Biopsy-proven nephritis was found in 16 (7.5%) patients. Severe GI involvement was present in 77 (36%) patients, whereas only 12 (5.6%) patients were diagnosed with intussusception and in 29 (13.5%) patients, HSP recurred. Neutrophil count and NLR were found higher in HSP patients with severe gastrointestinal involvement and biopsy-proven nephritis. Additionally, only platelet count was lower and MPV was higher in patients with recurrent HSP. Conclusion: Elevated neutrophil count and NLR may be relevant markers for severe GI involvement and nephritis, whereas platelet count and MPV were the only laboratory parameters associated with disease recurrence.

A Two-Month-Old Child with Vascular Ectasia: A Case Report Diagnosed by Molecular Karyotyping.

Gastrointestinal angiodysplasia can be encountered in cases with aortic stenosis, inflammatory gastrointestinal conditions, von Willebrand disease or vascular damage, and degenerative changes. Predisposing factors have been described in four adults with vascular ectasia located in the stomach, duodenum, and the distal esophagus. Here, we report a 2-month-old infant with vascular ectasia in the proximal esophagus and diagnosed by molecular karyotyping. This is the first case of vascular ectasia in the proximal esophagus in a pediatric patient.

Intravenous Paracetamol Overdose: A Pediatric Case Report.

Paracetamol is a common antipyretic often used to treat children with fever and pain. With the increasing administration of intravenous (IV) paracetamol, there will be the associated risk of medication dosing errors. We report a case of IV paracetamol overdose in a child with fever during hospital admission. A IV paracetamol dosing error occurred, with delayed recognition resulting in transient hepatotoxicity, with a peak alanine transaminase of 1946 IU/L and aspartate transaminase of 1633 IU/L.

Severe Troponin I Elevation and Myocardial Dysfunction in a Child with Scorpion Sting.

Background Scorpion sting is a common medical problem and major cause of mortality and morbidity in many countries. The symptoms of envenomation are more severe in the pediatric population. The clinical manifestations of scorpion envenomation appear by activation of sympathetic and parasympathetic nervous system. Envenomation can cause multiorgan dysfunction and death. Case Presentation and Findings In this case report, we present a pediatric patient from Adana, Southeast Anatolia, with severe scorpion envenomation with Leiurus abdullahbayrami which is an especially dangerous species for children. Severe systolic dysfunction was detected by echocardiography. Troponin I levels elevated significantly and rapidly responded to three doses of antivenom therapy. Conclusion Early echocardiographic examination is an important procedure for patients with scorpion envenomation. Troponin I is a significant parameter to monitor the degree of cardiac injury. Antivenom therapy is the only recommended specific therapy for children with severe scorpion envenomation due to Leiurus abdullahbayrami . Abnormal echocardiography findings may require repeated doses of scorpion antivenom.

Point-of-care lung ultrasound in children with community acquired pneumonia.

OBJECTIVES: To present lung ultrasound findings in children assessed with suspected pneumonia in the emergency department and to show the benefit of lung ultrasound in diagnosing pneumonia in comparison with chest X-rays. METHODS: This observational prospective study was performed in the pediatric emergency department of a single center. Point of care lung ultrasound was performed on each child by an independent sonographer blinded to the patient's clinical and chest X-ray findings. Community acquired pneumonia was established as a final diagnosis by two clinicians based on the recommendations in the British Thoracic Society guideline. RESULTS: One hundred sixty children with a mean age of 3.3±4years and a median age of 1.4years (min-max 0.08-17.5years) were investigated. Final diagnosis in 149 children was community-acquired pneumonia. Lung ultrasound findings were compatible with pneumonia in 142 (95.3%) of these 149 children, while chest X-ray findings were compatible with pneumonia in 132 (88.5%). Pneumonia was confirmed with lung ultrasound in 15 of the 17 patients (11.4%) not evaluated as compatible with pneumonia at chest X-ray. While pneumonia could not be confirmed with lung ultrasound in seven (4.6%) patients, findings compatible with pneumonia were not determined at chest X-ray in two of these patients. When lung ultrasound and chest X-ray were compared as diagnostic tools, a significant difference was observed between them (p=0.041). CONCLUSIONS: This study shows that lung ultrasound is at least as useful as chest X-ray in diagnosing children with community-acquired pneumonia.

The role of plasmapheresis in organophosphate poisoning: Case reports of three pediatric patients.

Yükselmis U, Özçetin M, Çag Y, Yildizdas D, Yilmaz HL. The role of plasmapheresis in organophosphate poisoning: Case reports of three pediatric patients. Turk J Pediatr 2017; 59: 491-496. The aim of the study was to assess the impact of plasmapheresis treatment in the management of three pediatric patients with organophosphate poisoning who did not respond to standard treatment. The treatment of signs and symptoms, and supportive treatment has been evaluated in this paper. Patients were initially given atropine infusion and 0.05 mg/kg atropine with five-minute intervals. Despite pralidoxime loading and three consecutively infusions clinical symptoms did not respond to the treatment and plasma pseudocholinesterase levels did not decrease. At this point, plasmapheresis was used on three consecutive days. Accordingly, the clinical signs improved and mechanical ventilation was no longer necessary. Patients were discharged on the sixteenth day after their admission to the hospital. Plasmapheresis may be an option for the patients who do not respond to atropine and pralidoxime treatment in organophosphate poisoning.

MyD 88 Polymorphisms in Children Diagnosed with Sepsis.

BACKGROUND: Myeloid differentiation primary response gene 88 (MyD 88) is an intracellular adapter protein that mediates the early immune response to pathogens. Toll-like receptors (except TLR-3) induce the immune response through a MyD 88-dependent signal pathway. AIMS: We aimed to investigate the MyD 88 polymorphisms that play important roles in the immune response in septic children and to evaluate whether or not they were risk factors in the development of sepsis. STUDY DESIGN: Case-control study. METHODS: Sixty-five patients diagnosed with sepsis in the Pediatric Intensive Care Unit during the period from April 2010 to January 2012 were included as the study group. Sixty-five children without sepsis were included as controls. After DNA was obtained from blood samples in the study and control groups, MyD 88 polymorphisms were analyzed. According to the genotype and allele frequencies, the distributions of MyD 88 polymorphisms [Single nucleotide polymorphism (SNP) - 938 C/A (rs4988453), MyD 88 SNP 1944 C/G (rs4988457)] were analyzed in both the study and control groups. RESULTS: The C/C genotype of MyD 88 SNP -938 was significantly more common than the C/A genotype in the patient group (p=0.002). No statistically significant difference in the frequency of the MyD 88 SNP 1944 genotype was found between the study and control groups (p=0.272). CONCLUSION: Gene polymorphism studies could elucidate our understanding of sepsis in terms of prevalence and the management of treatment. It was shown in this study that children with the MyD 88 SNP -938 C/C genotype had a greater tendency toward sepsis. However, additional studies should be performed.

Etomidate Versus Ketamine: Effective Use in Emergency Procedural Sedation for Pediatric Orthopedic Injuries.

OBJECTIVES: The aim of this study was to compare the induction and recovery times, postsedation observation durations, and adverse effects of etomidate and ketamine in pediatric patients with fractures and/or dislocations requiring closed reduction in the emergency department. METHODS: Forty-four healthy children aged 7 to 18 years were included. The patients were randomly divided into 2 groups. Group 1 (24 patients) received etomidate and fentanyl, and group 2 (20 patients) received ketamine intravenously. The Ramsay Sedation Scale and American Pediatric Association discharge criteria were used to evaluate the patients. RESULTS: There were 70 fractured bones and 3 joint dislocations. Except in 1 case (2.3%), all of the injuries were reducted successfully. The mean amount of drugs used to provide adequate sedation and analgesia were 0.25 mg/kg of etomidate and 1.30 µg/kg of fentanyl in group 1 and 1.25 mg/kg of ketamine in group 2. Fourteen patients (31.8%) reported adverse effects, and none required hospitalization. There was no difference between the groups in the recovery times, occurrence of adverse effects, and postsedation observation durations (P > 0.05). The mean (SD) induction time for the patients in group 1 was 4.3 (1.0) minutes, whereas it was 2.2 (1.6) minutes in group 2 (P < 0.001). CONCLUSIONS: Etomidate induces effective and adequate sedation in the pediatric emergency department for painful orthopedic procedures. Ketamine, which has longer action times, might be preferred for reductions because orthopedic procedures could be lengthy.

Comparison of midazolam and propofol for sedation in pediatric diagnostic imaging studies.

OBJECTIVE: This study aims to compare the efficacy of propofol and midazolam in terms of adverse effect potentials and to determine the appropriate strategy for pediatric procedural sedation. METHODS: A total of 200 pediatric patients (aged < 14 years) undergoing diagnostic procedures were recruited for this nonrandomized prospective controlled cohort study. The patients were assigned to 2 treatment arms: either propofol (Group 1: IV bolus dose of 2 mg/kg during a 2-minute period, IV maintenance dose of 100 mcg/kg/min) or midazolam (Group 2: IV bolus dose of 0.15 mg/kg during a period of 2 to 3 minutes) to achieve sedation. Demographic data, body weight, and clinical status of the patients were evaluated and recorded. The vital signs and sedation levels (ie, Ramsay sedation scale scores) were evaluated and recorded, as well as the complications detected and medications administered in 10-minute intervals throughout the sedation procedure. Findings between the study arms were compared. RESULTS: Arterial blood pressures decreased significantly in both groups (P = 0.001). The patients in Group 1 experienced a greater difference in diastolic blood pressure (P = 0.001) than those in Group 2. Sedation scores in Group 1 were more favorable (P = 0.014) and reached the appropriate sedation level in a shorter time than those in Group 2 (P = 0.010). Likewise, recovery time of patients was shorter in Group 1 than in Group 2 (P = 0.010). Hypoxia was found to be more common in the propofol group, but the difference was not significant (P = 0.333). CONCLUSION: Propofol seems to be more effective, achieve the appropriate sedation level more quickly, and provide a faster onset of sedation than midazolam in pediatric procedural sedation and analgesia. Propofol is preferred for imaging studies (computed tomography and magnetic resonance imaging) to reduce the occurrence of undesired motion artefacts. Although both drugs are safe to use for sedation before pediatric imaging procedures, propofol is preferred with appropriate preparation.

Effect of pediatric advanced life support course on pediatric residents' intubation success.

BACKGROUND: The Pediatric Advanced Life Support Program (PALS) course very important for teaching about intubation, resuscitation, shock, trauma, respiratory failure and rhythm disturbances. The aim of the present study was to evaluate the effect of the PALS course on pediatric residents' intubation success during their rotation, daytime and night-time practice in the pediatric intensive care unit (PICU). METHODS: The study was carried out from 1 March 2005 to 28 February 2007. The study period had two parts, in that the number of attempts and successful intubations performed by pediatric residents, and the pediatric intensivist successful intubation ratio were evaluated in two different periods: before the PALS course, 1 March 2005-28 February 2006, and after the PALS course, 5 March 2006-28 February 2007. The participating residents' pediatric levels (PL) were classed as PL-1, PL-2, PL-3, PL-4, and all had first experience in the PICU at the PL-1 level. The PALS instructor was a pediatric emergency or intensive care doctor. We evaluated whether the PALS course influenced intubation success or not. RESULTS: Sixteen residents participated in the study. The proportion of successful intubations was 110 (53.3%) and 104 (65.4%) attempts before and after the PALS course, respectively. The proportion of intubations done by intensivists decreased from 49.1% to 31.7% before and after PALS. The most frequently used endotracheal tube (ETT) internal diameter (ID) was 4.0 mm, and cuffed ETT was used 16% and 21% before and after the course, respectively. Appropriate placing of ETT tip occurred 70.4% and 82.2% of the time before and after the PALS course, respectively. Proportion of successful intubations by residents increased in all levels, except for PL-1. The most important reason for unsuccessful attempts was inappropriate patient position. Only one patient could not be intubated, and laryngeal mask airway was used in that case. During intubation, complications were broken teeth in two patients before the course, and subglottic stenosis developed in only one patient due to cuffed ETT. CONCLUSION: Successful intubation is a life-saving intervention during resuscitation, ETT revision for extubation or obstruction for extubation or obstruction during mechanical ventilation. This skill can be developed in the PALS course and by clinical study in PICU and pediatric emergency services. The PALS course must be given to pediatric residents especially within the first year. Also, cuffed ETT can be used for infants and children.

Metabolic acidosis in a patient with type 1 diabetes mellitus complicated by methanol and amitriptyline intoxication.

Diabetic ketoacidosis (DKA) is a widely known acute metabolic complication of diabetes mellitus (DM), which can be potentially fatal. It is not difficult to diagnose when a patient with DM comes with symptoms such as coma, fruity breath, hyperglycemia, acidosis, and tachypnea. If the patient has not been diagnosed with DM before, then other sicknesses characterized by an increased anion gap should be considered. A 12-year-old boy with type 1 DM and repeated earlier admissions for DKA was admitted to the emergency department in another apparent case of DKA with coma, hyperglycemia, and profound metabolic acidosis. When his condition did not improve with initial treatment, intoxication was suspected as an alternate cause of his condition. Further laboratory tests detected methanol and amitriptyline. The patient underwent hemodialysis and recovered completely. This case illustrates that a seemingly obvious medical condition can mask serious intoxication. This report is the only publication on two different entities characterized by an increased anion gap and at the end the patient has been cured completely without any complications.

Screening tools for bacteraemia in a selected population of febrile children.

INTRODUCTION: This is a prospective, observational study. The aims of the study were to determine the rate of bacteraemia in febrile children in Turkey, and to evaluate the usefulness of white blood cell (WBC) count and manual differential counts of peripheral blood smears and a RISK score in predicting bacteraemia among these children. MATERIALS AND METHODS: A total of 377 febrile children aged 3 to 36 months were included in the study. Complete blood cell (CBC) count, manual differential counts and blood cultures were performed in all patients. The main outcome measures used to evaluate the usefulness of the RISK score were sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), odds ratio (OR), posterior probability, areas under receiver operator characteristic curves (AUC) and miss-to-diagnosis ratio (MDR). RESULTS: Among the patients, 4.4% had bacteraemia and the predominant pathogen was Streptococcus pneumoniae. The Yale Observation Scale scores, percentages of neutrophil and bands, band-neutrophil ratio, absolute neutrophil count and absolute band count were found to be statistically significant predictors of bacteraemia. When the RISK score was 2 or higher, sensitivity was 93.8%, false positive ratio 35.8%, PPV 10.6%, NPV 99.5%, OR 26.2 (95% CI, 3.4 to 200.8), MDR 0.066 and posterior probability value 10%. CONCLUSIONS: We conclude that determination of the RISK score will significantly decrease unnecessary blood culture sampling, antibiotherapy and hospitalisation among febrile patients aged 3 to 36 months without an identifiable focus of infection.
