Simple and complex febrile seizures: is there such a difference? Management and complications in an emergency department.

OBJECTIVE: We aimed to analyse the prevalence, characteristics, and management of simple and complex febrile seizures. The secondary objective was to compare the risk of underlying organic lesion and epilepsy in both types of seizures, with a particular focus on the different subtypes defining a complex febrile seizure. MATERIAL AND METHODS: We performed a retrospective cohort study including patients aged 0--16 years who were treated for febrile seizures in the paediatric emergency department of a tertiary hospital over a period of 5 years. Epidemiological and clinical variables were collected. Patients were followed up for at least 2 years to confirm the final diagnosis. RESULTS: We identified 654 patients with febrile seizures, with a prevalence of 0.20% (95% CI, 0.18-0.22); 537 (82%) had simple febrile seizures and 117 (18%) had complex febrile seizures. The clinical and epidemiological characteristics of both types were similar. Significantly more complementary tests were requested for complex febrile seizures: blood tests (71.8% vs 24.2% for simple febrile seizures), urine analysis (10.3% vs 2.4%), lumbar puncture (14.5% vs 1.5%), and CT (7.7% vs 0%). Similarly, admission was indicated more frequently (41.0% vs 6.1%). Underlying organic lesions (central nervous system infection, metabolic disease, tumour/intracranial space-occupying lesion, intoxication) were diagnosed in only 11 patients, 5 of whom had complex forms (4.3%; 95% CI, 0.6-7.9). Risk factors for developing epilepsy, identified in the multivariate analysis, were complex forms with recurrent seizures in a single attack (odds ratio [OR]: 4.94; 95% CI, 1.29-18.95), history of seizures (OR: 17.97; 95% CI, 2.26--143.10), and seizures presenting at atypical ages (OR: 11.69; 95% CI, 1.99-68.61). CONCLUSIONS: The systematic indication of complementary tests or hospital admission of patients with complex febrile seizures is unnecessary. The risk of epilepsy in patients with complex forms gives rise to the need for follow-up in paediatric neurology departments.

[Perceived quality of care by frequent paediatric healthcare users: A qualitative approach]. / Calidad percibida en población hiperfrecuentadora infantil: una aproximación cualitativa.

INTRODUCTION: Assessing the perceived quality of a healthcare department by its users is essential in a quality management system. In Paediatric Emergency Departments (PED), the demand for urgent care has increased in recent years, as well as an increase in frequent attendance. Paying attention to the opinions of these habitual users by means of qualitative methodology is particularly suitable for assessing the quality of care and identifying opportunities to improve the PED. METHODS: Two focus groups were held with parents of patients (with and without a chronic disease) who visited the PED on 10or more occasions per year in a third level hospital. RESULTS: The participants were satisfied overall with the PED. The treatment received was very positively valued, and they never felt that they had received poorer care due to being frequent users. As main strengths, they also highlighted the professional expertise, the friendliness of staff, the quality of information given, the medication received on discharge from hospital, and the follow-up carried out by the PED. The major improvement opportunities identified included: the contagion risks, the lack of coordination between different levels of care, and the need to improve the inclusion of families in the health care process. CONCLUSIONS: Due to the contributions made by these parents, several improvement strategies have been introduced, such as the implementation of sharing information protocols in shift changes, professional training courses, the establishment of a liaison person between the PED and Primary Care, and a proposal to the Hospital Management Department to assess the identified needs.

[Impact of a strategy to improve the quality of care and risk management in a paediatric emergency department]. / Impacto de una estrategia de mejora de calidad asistencial y gestión de riesgos en un servicio de urgencias pediátricas.

INTRODUCTION: Emergency departments are a high risk area for the occurrence of adverse events. The aim of this study is to analyse the impact of a strategy to improve the quality assurance and risk management in the notification of incidents in our Unit, and describe the improvement actions developed from the reported incidents. MATERIAL AND METHODS: A retrospective observational study was developed during one year, divided into two periods: P1 (Start: training session and implementation of the risk management process), and P2 (Start: feed-back session of incidents reported in P1 and improvement actions developed). In each period, the number of reported incidents in relation to the number of emergencies attended (‰) and the descriptive data of each incident were recorded. The improvement actions developed from the incidents reported in P1 were described. RESULTS: The number of notifications from P1 (4.1‰; 95%CI 3.2-5.0‰) increased in P2 (10.9‰; 95%CI 9.8-10.2‰, P<.001). The most frequent incidents in P1 were medication (33.3%), and identification errors (25.9%): both were significantly reduced in P2 (16.9%, P=.001 and 9.3%, P<.001, respectively). In P2, prescription errors of the P1 were reduced (35.9% vs 62.9%, P=.02). The factors of "Knowledge and training" (23.5%) were the most frequent in P1, decreasing in P2 (7.4%, P<.001). CONCLUSION: It is considered that the implementation of a risk management process, and the promotion of a safety culture, through training and feed-back sessions to all professionals, contributed to increase the volume of notifications in our Unit. The voluntary and anonymous reporting of incidents is useful to identify risks, and plan corrective measures, contributing to improve quality assurance and patient safety.

[Association between moderate-severe bronchiolitis and syndrome of inappropriate antidiuretic hormone secretion in emergency departments]. / Asociación entre bronquiolitis moderada-grave y síndrome de secreción inadecuada de hormona antidiurética en urgencias.

OBJECTIVES: To identify clinical characteristics that may lead to the early recognition of patients admitted to the hospital for moderate-to-severe bronchiolitis with urine results associated with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). PATIENTS AND METHODS: A prospective observational study was conducted, spanning the bronchiolitis epidemic season (October 2012-March 2013), including all children who were admitted to the hospital with a diagnosis of moderate-to-severe bronchiolitis. The following criteria were used to establish a diagnosis of SIADH: urine sodium level of 40 mmol/L or greater, urine osmolarity above 500 mosm/Kg, and urine density of 1020 g/L or greater. Demographic characteristics, ventilation mode and clinical outcome were also analyzed. A comparison was made between those patients that met urine SIADH criteria and those who did not. RESULTS: A total of 126 children were included, and 23 (18.6%) of them had urine SIADH criteria. Patients in this group had a higher incidence of pneumonia and/or atelectasis on chest X-Ray (21.7% vs. 1.9%, P=.002), worse response to bronchodilator treatment with nebulized adrenaline (69,5% vs. 28,1%, P=.016), more need for respiratory assistance (high flow oxygen therapy (17.4% vs. 7.7%, p=.016), or non-invasive mechanical ventilation (13% vs. 5.8%, P=.034), and more admissions to the PICU (26.1% vs. 6.8%, P=.007). CONCLUSIONS: Patients older than one month with acute moderate bronchiolitis and urine SIADH criteria have worse clinical courses and more need for non-invasive mechanical ventilation, PICU admission, and have a higher incidence of pneumonia on chest X-ray. For that reason, it is recommended to collect a urine sample from these patients to allow an early diagnosis of SIADH, and thus early treatment of fluid and electrolyte abnormalities.

[Heliox-driven bronchodilator nebulization in the treatment of infants with bronchiolitis]. / Heliox como fuente de nebulización del tratamiento broncodilatador en lactantes con bronquiolitis.

INTRODUCTION: Heliox is a helium-oxygen mixture which improves laminar flow and decreases airway resistance and the work of breathing. The aim of this study was to assess the effects of salbutamol or epinephrine nebulization driven by heliox in infants with moderate-to-severe bronchiolitis. MATERIALS AND METHODS: This prospective, observational, interventional, controlled and randomized study included ninety-six children who came to our pediatric emergency department with first episode of moderate-to-severe bronchiolitis. The patients were randomized to receive salbutamol or epinephrine nebulized with either oxygen (control group) or heliox (70% helium and 30% oxygen) as the driving gas. Heart rate, respiratory rate, pulse oximetry oxygen saturation and clinical score were measured before and after the treatment period. We also reported hospitalization rates and the number of patients who returned to the emergency department in the following seventy two hours. RESULTS: There were no significant differences between both groups. The only statistically significant difference was that, in the heliox group, patients with severe bronchiolitis needed a lower number of nebulizations than infants in the control group. CONCLUSIONS: According to our study, heliox-driven salbutamol or epinephrine is not an effective therapy in patients with acute bronchiolitis.

[Incidence of streptococcal pharyngitis]. / Incidencia de faringitis estreptocócica.

OBJECTIVE: To determine the incidence of streptococcal pharyngitis in patients younger than 2 years of age, and to evaluate the role of group C streptococci as a pathogenic agent in acute pharyngitis through throat culture in symptomatic patients. MATERIAL AND METHODS: We performed a retrospective descriptive study of patients with clinical symptoms of acute pharyngitis and fast detection of streptococcal antigen and/or exudate culture who attended the emergency department between February 2004 and February 2005. RESULTS: Group A beta-hemolytic streptococcus (GAS) was isolated by pharyngeal culture in 85 patients aged less than 2 years (12.6%). In these patients the fast test displayed lower sensitivity and positive predictive value (PPV) (sensitivity: 78%; PPV: 69%, p < 0.01). Patients aged less than 2 years had a greater frequency fever, exanthema and catarrhal symptoms than older children (p < 0.01). In the younger age group, erythromycin resistance rates increased to 24.7% (p = 0.08). Group C streptococcus was isolated in 5.2% (43 patients). The most frequent reason for consultation was fever (74.4%) and the most common findings on examination were abnormal pharynx in 90.7%, odynophagia and adenopathies in 55.8%. Two incidence peaks (in May and September) were observed, with sporadic cases throughout the year. CONCLUSIONS: In our sample, the percentage of GAS in patients aged less than 2 years was higher than that reported in other series. In this age group, the sensitivity of the fast test is lower than in other age groups and there is a higher rate of erythromycin resistance. The percentage of tonsillitis due to serotype C was also slightly higher than expected. Two peaks of incidence were observed, similar to those occurring with SGA, with sporadic cases throughout the year.

[Aortic and cerebral trombosis caused by hypernatremic dehydration in an exclusively breast-fed infant]. / Trombosis aórtica y cerebral secundarias a deshidratación hipernatrémica en un recién nacido con lactancia materna exclusiva.

Complete aortic thrombosis is rare in neonates. Because it carries high morbidity and mortality, this entity requires aggressive and early treatment. This report describes an 8-day-old healthy and exclusively breast-fed infant, without specific coagulopathy, who developed complete aortic and cerebral venous thrombosis, which was attributed to inadequate breast-feeding and severe hypernatremic dehydration. Early systemic anticoagulation and thrombolytic therapy allowed complete resolution of the problem.

[Psychiatric patients in the pediatric emergency department of a tertiary care center: review of a 6-month period]. / Pacientes psiquiátricos en el servicio de urgencias de pediatría de un hospital terciario: revisión de un período de 6 meses.

INTRODUCTION: In the last few years, a marked increase in the number of psychiatric emergencies treated at pediatric emergency departments has been observed. The aim of the present study was to characterize these patients. PATIENTS AND METHODS: We performed a descriptive, prospective, cross sectional study, based on all psychiatric emergencies treated at the pediatric emergency department of Hospital General Universitario Gregorio Marañón, Madrid, from 1-10-04 to 31-3-05. The following variables were analyzed: age, sex, time of consultation, day of the week, day of the month, month of the year, psychiatric antecedents, previous psychiatric pharmacologic treatment, the person or service who took the child to hospital, diagnosis, and whether the patient was admitted to the hospital. RESULTS: Of a total of 36,449 emergencies, 79 were psychiatric (0.21 %). Sex rates were 48.1 % boys and 51.9 % girls. The mean (+/-2 SD) age was 13.73 +/- 2.5 years. Visits were most frequent on Mondays (19 %), in the evening, and in January and February. A total of 13.23 % of the patients were brought by extrahospital services. The main diagnoses were: behavioral disorders (36.76 %), anxiety disorders (20.58 %) and suicidal ideation or suicide attempt (13.23 %). There was a clear male predominance in behavioral disorders (67.85 %) and a female predominance in anxiety disorders (71.42 %) and suicidal ideation or suicide attempt (76.92 %). The hospitalization rate among these patients was 32.35 %. CONCLUSIONS: The incidence of psychiatric disorders in our pediatric emergency department was low. The patients were aged 11-15 years old, without differences between the sexes. Peak demand was reached on Mondays in January and February, at the end of the evening and beginning of the night. The most common diagnosis was behavioral disorder. The hospitalization rate was exceptionally high, more than 6 times higher than the average in our hospital.

[Isolation of group A beta-hemolytic Streptococcus in children with perianal dermatitis]. / Aislamiento de estreptococo betahemolítico del grupo A en niños con dermatitis perianal.

INTRODUCTION: Perianal dermatitis due to group A beta-hemolytic streptococcus is a rare diagnosis in pediatrics. Clinical manifestations include erythema, edema, and perianal pruritus associated with vulvovaginitis or balanitis, painful defecation, constipation, anal fissures, purulent discharge, and/or rectal bleeding. MATERIAL AND METHODS: A descriptive, observational, prospective study was conducted between May, 2004 and April, 2005. In children presenting to the emergency room with erythema, edema, and perianal pruritus, a rapid streptococcal antigen test and bacterial cultures of their perianal secretions were obtained. Patients with a positive result in the rapid test were treated with oral phenoxymethylpenicillin (40-50 mg/kg/day) for 10 days, after which clinical and bacteriological evaluations were conducted. RESULTS: Of the 24 patients presenting with erythema, edema, and perianal pruritus, 19 patients (12 boys and 7 girls), aged between 6 months and 4 years (median age: 30 months), tested positive for group A beta-hemolytic streptococcus. Nine patients also presented with constipation, 5 with anal fissures, 4 with rectal bleeding, 2 with vulvovaginitis, and 1 with streptococcal pharyngoamygdalitis. Outcome was favorable in 85 % of the patients, and perianal isolation of group A beta-hemolytic streptococcus was negative after treatment in 95 %. CONCLUSIONS: In patients presenting with erythema, edema, and perianal pruritus, perianal streptococcal dermatitis should be ruled out. The rapid test for streptococcal antigen detection is a quick and reliable method for this diagnosis. The antibiotic of choice is oral penicillin.

[Diaphragmatic paralysis in the postoperative period after heart surgery in children]. / Parálisis diafragmática en el postoperatorio de cirugía cardíaca en la infancia.

OBJECTIVE: The purpose of our study was to determine the incidence, pathological features, clinical relevance and treatment of diaphragmatic paralysis (DP) after pediatric cardiac surgery. PATIENTS AND METHODS: Five hundred fifty-six children who had undergone cardiac surgery between 1990 and 1994 were retrospectively analyzed. Persistent raising of one or both hemidiaphragms on chest x-ray films lead to the diagnosis in all cases. RESULTS: Diaphragmatic paralysis was diagnosed in 13 patients (2.3%) ranging from 3 days to 13 years of age. Atrial septal defect closure (3 cases) and systemic-pulmonary shunt derivations (3 cases) were the type of operations most frequently involved. The other cases included, 2 arterial switch in transposition of the great vessels, 1 repair of total anomalous pulmonary venous drainage, 1 tetralogy of Fallot repair, 1 coarctation and aortic stenosis repair, 1 resection of subpulmonary stenosis of transposition of the great vessels and 1 pacemaker implantation. There was no significant association with the use of extracorporeal circulation. There were seven cases of right hemidiaphragmatic paralysis, but no bilateral paralysis was found. Ipsilateral thoracotomy section concordance was found in all patients and no relation with central venous line placement was found. Diagnosis was made by chest x-ray in all cases, and further confirmation was done using fluoroscopy in 6 patients and ultrasound studies in 2. Prolonged mechanical ventilation was needed in 3 patients, and one patient required diaphragmatic plication. No long term complications were found. CONCLUSIONS: Diaphragmatic paralysis is a rare complication of pediatric cardiac surgery which must be suspected when failed attempts of respiratory weaning, not attributable to cardiac or pulmonary problems, are present.
