Clinical trial: oral ondansetron for reducing vomiting secondary to acute gastroenteritis in children – a double-blind randomized study

Background  Vomiting as a consequence of gastroenteritis frequently occurs in children. It is still debatable whether vomiting should be treated with antiemetic drugs.

Severe scorpion envenomation in children: Management in pediatric intensive care unit

Background: Scorpion envenomation is a common public health problem worldwide and children are at greater risk of developing severe cardiac, respiratory and neurological complications. The aim of this study was to evaluate the effects of antivenin and/or prazosin use on prognosis of scorpion-envenomed children admitted to pediatric intensive care unit (PICU). Methods: The standardized medical records of 45 children hospitalized with severe scorpion sting in PICU were retrospectively evaluated. General characteristics of the children, clinical and laboratory findings, treatment approaches and prognosis were evaluated. Results: The mean age of the patients were 6.1 ± 4.1 years ranging between 4 month and 15 years. Male to female ratio was 1.8. Thirty-three (71.1%) cases of scorpion stings came from rural areas. Twenty-six (57.8%) of the patients were stung by Androctonus crassicauda. The most common sting localization was the foot-leg (55.6%). The mean duration from the scorpion sting to hospital admission was 4.5 ± 2.6 hours. The most common findings at presentation were cold extremities (95.5%), excessive sweating (91.1%) and tachycardia (77.7%). The mean leukocyte count, and serum levels of glucose, lactate dehydrogenase, creatine phosphokinase and international normalized ratio were found above the normal ranges. Prazosin was used in all patients, dopamine in 11 (24.4%) and Na-nitroprusside in 4 (8.8%) patients. Two children died (4.4%) due to pulmonary oedema. These children, in poor clinical status at hospital admission, needed mechanical ventilation, and death occurred despite use of antivenin and prazosin in both of them. Conclusion: The current management of children with severe scorpion envenomation consists of administration of specific antivenom and close surveillance in a PICU, where vital signs and continuous monitoring enable early initiation of therapy for life-threatening complications. The aggressive medical management directed at the organ system specifically can be effective. Our data indicated that when admission to hospital is late, the beneficial effect of antivenom and/or prazosin is questionable in severe scorpion stings.

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 patients 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 ± 4 years and a median age of 1.4 years (min–max 0.08–17.5 years) 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.

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

Abstract 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.

Intramuscular dipyrone versus oral ibuprofen or nimesulide for reduction of fever in the outpatient setting

AbstractObjective: To compare the effectiveness and rate of temperature reduction of three antipyretic medications in febrile children. Design: A single-dose, randomised, prospective, modified double-blind, parallel clinical trial. Setting: The paediatric emergency department of a university hospital that has 13 000 annual visits. Study participants: 252 otherwise healthy children aged 6 months to 14 years with acute, intercurrent, febrile illness. Interventions: Enrolled children were assigned to receive a single dose of oral ibuprofen 10 mg/kg, oral nimesulide 2.5 mg/kg, or parenteral dipyrone 10 mg/kg. Main outcome measures and results: Axillary temperature was measured at the time of antipyretic administration and at 30, 45, 60 and 120 minutes thereafter. All three medications were effective in reducing the axillary temperature during the 2-hour testing period. The rates of axillary temperature change between the three medications were significantly different for the ibuprofen and dipyrone groups (p = 0.023). In addition, the axillary temperature in the dipyrone group was significantly lower than that in the ibuprofen group (p = 0.036) at 120 minutes. There was no significant difference in antipyretic effect between the nimesulide group and the other two groups during the testing period. Within each group the difference between initial temperature and the temperature at the end of the testing period was statistically significant (p = 0.036) for the dipyrone group only. Conclusions: All three antipyretic medications were effective in reducing the axillary temperature in febrile children. Although administration of intramuscular dipyrone seemed to be more effective than ibuprofen, this relationship was not significant when nimesulide was considered. In addition, in view of its known side effects and the problems associated with intramuscular administration in children, the preference for orally administered nimesulide or ibuprofen over dipyrone in the setting of the emergency department seems more logical provided that the child accepts oral therapy.

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 &mgr;g/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.

Myocarditis and Early Markers of Cardiac Response Associated with Scorpion Stings in Children

INTRODUCTION A clinical course ranging from mild local findings to life-threatening systemic findings may occur after scorpion stings. The purpose of this study was to identify priority markers indicating scorpion sting-related cardiac involvement. METHODS Our study was performed between July 2014, and September 2015 in the Çukurova University medical faculty pediatric emergency department, in Adana, Turkey. Patients admitted with scorpion sting-related cardiac involvement and a control group consisting of patients with no scorpion sting-related cardiac involvement were included in the study. Troponin I at time of presentation and at 6 and 24 h, N-terminal prohormone of brain natriuretic peptide (NTproBNP), ejection fraction as determined by echocardiography at 24 h, and peak and end of T wave (Tp-e) and Tp-e/QTc ratios with echocardiography at 24 h were evaluated. RESULTS A patient group consisting of 7 cases of scorpion envenomation-related myocarditis and a control group of 30 cases of scorpion intoxication without myocarditis findings were enrolled. Statistically significantly high glucose, white blood cell values, creatine kinase MB, troponin I, and NTproBNP values were identified in the scorpion sting-related myocarditis group (P<0.05). Ejection fractions determined by echocardiography at time of presentation were significantly lower in the patients with myocarditis compared with the control group (P<0.05). A statistically significant difference was identified between Tp-e/corrected QT interval (QTc) ratios investigated in DI and V2 derivations in patient and control group echocardiograms (P<0.05). CONCLUSIONS We think that use can be made of NTproBNP in addition to echocardiography and troponin I in the early diagnosis of scorpion sting-related myocarditis and that Tp-e and Tp-e/QTc ratios identified via echocardiography can be used as early markers; however, further studies with larger numbers are needed to confirm this.

Künt Batın Travmasında Odaklanmış Travma Ultrasonografinin Yararı

Trauma is an important health problem that develops with preventable causes. The gold standard method for detecting intraperitoneal free fluid as a result of blunt abdominal trauma is a computerized tomography examination. Other alternative method is bedside ultrasonography method which facilitate diagnosis and follow-up. Hemodynamically unstable trauma patients may be able to evaluated with focused ultrasound on bedside and perform emergency treatment directly in the operating room without time-consuming at the times with vital care. This case, which is a case of low energy trauma which is diagnosed as intraperitoneal free fluid with focused trauma ultrasonography made and has no clinical findings except only with deep palpation when presented, is presented in order to emphasize the power and management with the method.

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.

Urticaria as a Rare Side Effect of Polyethylene Glycol-3350 in a Child: Case Report

SUMMARY – Polyethylene glycol electrolyte (PEG-3350) solution is usually used for bowel emptying before colonoscopy in adults. It has also been reported to be safe in children. It is thought that bowel irrigation with this solution can be a useful treatment alternative for poisoning with slow releasing drugs, swallowed packaged substances, enteric coated drugs, drugs not binding to charcoal, and heavy metals in children. Due to high molecular weight of PEG-3350, its absorption from the intestinal mucosa is very low (0.2%). Therefore, it is less likely to have side effects. A three-year-old girl bit and ate one-third of an alkali battery and was brought to our pediatric emergency unit. Vital signs and results of physical examination and laboratory investigations were normal. Irrigation of the bowels with PEG-3350 solution given orally at a rate of 20 mL/kg/h was initiated. Upon excretion of feces of normal appearance in the sixth hour, irrigation was continued. Since rashes and itching started throughout her body in the thirtieth hour after administration of 9 L PEG-3350, the irrigation was discontinued and the patient was administered antihistamines. Rashes and itching regressed within one hour of its discontinuation. This suggested that they were due to the irrigation solution. There are five adult cases of allergic reactions to PEG-3350 reported in the literature. The case presented is the first pediatric patient developing allergic reaction to PEG-3350.
