The Diet of Preschool Children in the Mediterranean Countries of the European Union: A Systematic Review

This systematic review discusses data on the dietary intake of preschool children living in the Mediterranean countries of the European Union, including the comparison with a Mediterranean-like diet and the association with nutritional status. Specifically, data from the multinational European Identification and Prevention on Dietary and life style induced health effects in children and infants (IDEFICS) study and national studies, such as the Estudo do Padrão Alimentar e de Crescimento Infantil (EPACI) study and Geração XXI cohort in Portugal, ALimentando la SAlud del MAñana (ALSALMA) study in Spain, Étude des Déterminants pré-et postnatals précoces du développement et de la santé de l'ENfant (EDEN) cohort in France, Nutrintake 636 study in Italy, and Growth, Exercise and Nutrition Epidemiological Study in preSchoolers (GENESIS) cohort in Greece, were analyzed. In the majority of countries, young children consumed fruit and vegetables quite frequently, but also consumed sugared beverages and snacks. High energy and high protein intakes mainly from dairy products were found in the majority of countries. The majority of children also consumed excessive sodium intake. Early high prevalence of overweight and obesity was found, and both early consumption of energy-dense foods and overweight seemed to track across toddler and preschool ages. Most children living in the analyzed countries showed low adherence to a Mediterranean-like diet, which in turn was associated with being overweight/obese. Unhealthier diets were associated with lower maternal educational level and parental unemployment. Programs promoting adherence of young children to the traditional Mediterranean diet should be part of a multi-intervention strategy for the prevention and treatment of pediatric overweight and obesity.

Cerebral Sinovenous Thrombosis in Children: Clinical Presentation and Extension, Localization and Recanalization of Thrombosis

Many important questions regarding pathophysiology and treatment of cerebral sinovenous thrombosis need clarification and may depend on further knowledge on the etiology, site, extension and recanalization of the thrombosis. We studied these variables in a cohort of children and adolescents from seven Portuguese Centers. We conclude from our results that the deep venous system and the superior longitudinal sinus are less frequently affected with thrombosis but have a greater potential for serious neurologic disease and for major sequelae. Non-recanalization, at least in the long term, is not an adverse prognostic factor. Extensive propagation of the thrombus from the initial site of origin seems to be common. The early identification of risk factors and their treatment coupled with an aggressive attitude towards diagnosis and treatment for thrombosis involving the deep venous system would be warranted.

Mutilations Due to Medical Disorders in Children

Soft-tissue and bone necrosis, although rare in childhood, occasionally occur in the course of infectious diseases, either viral or bacterial, and seem to be the result of hypoperfusion on a background of disseminated intravascular coagulation. Treatment consists in correction of septic shock and control of necrosis. Necrosis, once started, shows extraordinarily rapid evolution, leading to soft-tissue and bone destruction and resulting in anatomic, functional, psychological, and social handicaps. Ten mutilated children were treated from January 1986 to January 1999 in Hospital de Dona Estefaˆ nia, Lisbon, Portugal. One was recovering from hemolytic-uremic syndrome with a severe combined immunodeficiency, another malnourished, anemic child had malaria, and three had chicken pox (in one case complicated by meningococcal septicemia). There were three cases of meningococcal and two of pyocyanic septicemia (one in a burned child and one in a patient with infectious mononucleosis). The lower limbs (knee,leg, foot) were involved in five cases, the face (ear, nose, lip) in four, the perineum in three, the pelvis (inguinal region, iliac crest) in two, the axilla in one, and the upper limb (radius, hand) in two. Primary prevention is based on early recognition of risk factors and timely correction. Secondary prevention consists of immediate etiologic and thrombolytic treatment to restrict the area of necrosis. Tertiary prevention relies on adequate rehabilitation with physiotherapy and secondary operations to obtain the best possible functional and esthetic result.

Cold Urticaria and Infectious Mononucleosis in Children

Physical urticaria includes a heterogeneous group of disorders characterized by the development of urticarial lesions and/or angioedema after exposure to certain physical stimuli. The authors present the case of a child with severe acquired cold urticaria secondary to infectious mononucleosis. Avoidance of exposure to cold was recommended; prophylactic treatment with ketotifen and cetirizine was begun and a self-administered epinephrine kit was prescribed. The results of ice cube test and symptoms significantly improved. Physical urticaria, which involves complex pathogenesis, clinical course and therapy, may be potentially life threatening. Evaluation and diagnosis are especially important in children. To our knowledge this is the first description of persistent severe cold-induced urticaria associated with infectious mononucleosis in a child.

Origem Anómala da Artéria Coronária Esquerda a Partir da Artéria Pulmonar

OBJECTIVE: To assess the frequency and severity of the anomalous origin of the left coronary artery (ALCA) from the pulmonary artery (PA). DESIGN OF THE STUDY: Prospective study of case series between March 1991 and December 1994. SETTING: Referral-based Paediatric Cardiology Department of a Tertiary Care Center. PATIENTS AND METHODS: Five consecutive patients (pts) with anomalous origin of the LCA from the PA; there were three infants aged 4 months and two children one 8 year and one 9 year old. There were three girls and two boys. All pts had clinical and 2D-echo and Doppler investigation prior to cardiac catheterization (CC). Indication for CC was based in the association of symptoms and signs of myocarditis or dilated cardiomyopathy of acute or subacute onset and electrocardiographic (ECG) signs of ischemia in infants. In older patients (pts) diagnosis was suspected mainly from ECG. During CC in all pts, aortograms and when necessary selective coronary angiograms were performed. Surgical correction was performed in all children. In two pts stress exercise ECG and stress Thallium studies before and after surgery were performed. RESULTS: two pts had "adult" an three had "infantile" type of ALCA from the PA. CC was performed and diagnosis was confirmed at surgery in all cases. In one child, correct diagnosis was made by ECO prior to CC and in one case LCA to PA fistula was suspected on Colour-Doppler study. No complications were attributed to CC. Several types of surgery were performed: reimplantation of the ALCA from the PA to the aorta (three pts); tunnel connection of the aorta to the ALCA via the PA (one pt) and left internal mammary to LCA anastomosis (one pt). Two infants died intraoperatively due to extensive myocardial infarction and poor left ventricular function. All the three survivors are asymptomatic after a mean follow up of 34 months. Two oldest pts are currently in New York Heart Association functional class I with normal ECG and improved myocardial perfusion on Thallium scan despite almost total occlusion of LCA at the site of implantation in the aorta as diagnosed on coronary angiogram. CONCLUSIONS: ALCA from PA is associated with major morbidity and mortality. Diagnosis should be suspected in pts with unexplained myocardial ischemia on ECG and even more if it is associated to clinical signs of dilated cardiomyopathy or myocarditis. Careful assessment on ECO and pulsed Doppler and colour flow mapping should make the diagnosis in most cases. Although surgery can be performed based only on ECO diagnosis, we strongly advise for angiography in all cases as in our experience there are false negative diagnosis by ECO. Preoperative Thallium studies can be useful for the selection of the type of surgery as pts with very little viable myocardium will not survive the establishment of a direct systemic to coronary blood flow and may be candidates for heart transplantation.

Prognostic Value of a New Cardiopulmonary Exercise Testing Parameter in Chronic Heart Failure: Oxygen Uptake Efficiency at Peak Exercise - Comparison with Oxygen Uptake Efficiency Slope

INTRODUCTION: A growing body of evidence shows the prognostic value of oxygen uptake efficiency slope (OUES), a cardiopulmonary exercise test (CPET) parameter derived from the logarithmic relationship between O(2) consumption (VO(2)) and minute ventilation (VE) in patients with chronic heart failure (CHF). OBJECTIVE: To evaluate the prognostic value of a new CPET parameter - peak oxygen uptake efficiency (POUE) - and to compare it with OUES in patients with CHF. METHODS: We prospectively studied 206 consecutive patients with stable CHF due to dilated cardiomyopathy - 153 male, aged 53.3±13.0 years, 35.4% of ischemic etiology, left ventricular ejection fraction 27.7±8.0%, 81.1% in sinus rhythm, 97.1% receiving ACE-Is or ARBs, 78.2% beta-blockers and 60.2% spironolactone - who performed a first maximal symptom-limited treadmill CPET, using the modified Bruce protocol. In 33% of patients an cardioverter-defibrillator (ICD) or cardiac resynchronization therapy device (CRT-D) was implanted during follow-up. Peak VO(2), percentage of predicted peak VO(2), VE/VCO(2) slope, OUES and POUE were analyzed. OUES was calculated using the formula VO(2) (l/min) = OUES (log(10)VE) + b. POUE was calculated as pVO(2) (l/min) / log(10)peakVE (l/min). Correlation coefficients between the studied parameters were obtained. The prognosis of each variable adjusted for age was evaluated through Cox proportional hazard models and R2 percent (R2%) and V index (V6) were used as measures of the predictive accuracy of events of each of these variables. Receiver operating characteristic (ROC) curves from logistic regression models were used to determine the cut-offs for OUES and POUE. RESULTS: pVO(2): 20.5±5.9; percentage of predicted peak VO(2): 68.6±18.2; VE/VCO(2) slope: 30.6±8.3; OUES: 1.85±0.61; POUE: 0.88±0.27. During a mean follow-up of 33.1±14.8 months, 45 (21.8%) patients died, 10 (4.9%) underwent urgent heart transplantation and in three patients (1.5%) a left ventricular assist device was implanted. All variables proved to be independent predictors of this combined event; however, VE/VCO2 slope was most strongly associated with events (HR 11.14). In this population, POUE was associated with a higher risk of events than OUES (HR 9.61 vs. 7.01), and was also a better predictor of events (R2: 28.91 vs. 22.37). CONCLUSION: POUE was more strongly associated with death, urgent heart transplantation and implantation of a left ventricular assist device and proved to be a better predictor of events than OUES. These results suggest that this new parameter can increase the prognostic value of CPET in patients with CHF.

Epilepsy and Cerebral Palsy: Characteristics and Trends in Children Born in 1976 - 1998

Background: Although epilepsy is common in children with cerebral palsy (CP), no data exists on prevalence rates of CP and epilepsy. Aims: To describe epilepsy in children with CP, and to examine the association between epilepsy and neonatal characteristics, associated impairments and CP subtypes. Methods: Data on 9654 children with CP born between 1976 and 1998 and registered in 17 European registers belonging to the SCPE network (Surveillance of Cerebral Palsy in Europe)were analyzed. Results: A total of 3424 (35%) children had a history of epilepsy. Among them, seventy-two percent were on medication at time of registration. Epilepsy was more frequent in children with a dyskinetic or bilateral spastic type and with other associated impairments. The prevalence of CP with epilepsy was 0.69 (99% CI, 0.66e0.72) per 1000 live births and followed a quadratic trend with an increase from 1976 to 1983 and a decrease afterwards. Neonatal characteristics independently associated with epilepsy were the presence of a brain malformation or a syndrome, a term or moderately preterm birth compared with a very premature birth, and signs of perinatal distress including neonatal seizures, neonatal ventilation and admission to a neonatal care unit. Conclusions: The prevalence of CP with epilepsy followed a quadratic trend in 1976e1998 and mirrored that of the prevalence of CP during this period. The observed relationship between epilepsy and associated impairments was expected; however it requires longitudinal studies to be better understood.

Risk Factors for Latex Sensitization in Children with Spina Bifida

Background: Children with spina bifida represent the major risk group for latex sensitization. Purpose: To determine the prevalence of latex sensitization in these children and to identify risk factors. Material and methods: We studied 57 patients with spina bifida. The mean age was 5.6 years and the male/female ratio was 0.8/1. In all patients a questionnaire, skin prick test (SPT) with latex (UCBStallergènes, Lofarma and ALK-Abelló), common aeroallergens and fruits (UCB-Stallergènes) and serum determination of total IgE (AlaSTAT) were performed. Results: The prevalence of latex sensitization was 30 %; only two sensitized children (12 %) had symptoms after exposure. Risk factors for latex sensitization were age 5 years (p = 0.008; OR = 6.0; 95% CI = 1.7-22.1), having at least four previous surgical interventions (p < 0.0001; OR = 18.5; 95% CI = 3.6-94.8), having undergone surgery in the first 3 months of life (p = 0.008; OR = 5.4; 95% CI = 0.7-29.2) and total serum IgE 44 IU/ml (p = 0.03; OR = 3.8; 95 %CI = 1.1-13.1). Multiple logistic regression analysis showed that only a history of four or more surgical interventions (p < 0.0001; OR = 26.3; 95 %CI = 2.9-234.2) and total serum IgE 44 IU/ml (p = 0.02; OR = 8.6; 95% CI = 1.4-53.4) were independently associated with latex sensitization. Sex, family and personal allergic history, hydrocephalus with ventriculoperitoneal shunt, cystourethrograms, intermittent bladder catheterization and atopy were not related to latex sensitization. Conclusions: In children with spina bifida, significant and independent risk factors identified for latex sensitization were multiple interventions and higher levels of total serum IgE. A prospective study will clarify the clinical evolution of assymptomatic children sensitized to latex.

Tranexamic Acid for Major Spinal Surgery in Children. A Retrospective Study

Introduction: Paediatric patients who undergo posterior spinal fusion surgery to correct scoliosis often require multiple blood transfusions. Tranexamic acid is a synthetic antifibrinolytic drug that reduces transfusion requirements in scoliosis surgery (1),(2),(3). Methods: To evaluate the efficacy of prophylactic tranexamic acid (TA) (initial dose of 10mg/kg and infusion of 1mg.kg(-1).h(-1)) in reducing perioperative blood transfusion requirements, we reviewed patients files and compared the amount of blood lost and blood transfused in the perioperative period of 12 patients (54.5%) that received TA and 10 patients (45.5%) who did not received TA. T-Student test was applied. Results: The average difference of blood losses (2,67 +/- 6,06ml) and blood transfused (212,9 +/- 101,1ml) between the two groups was not statistically significant (p>0.05). No thrombotic complications were detected in either group. Discussion: Results of the current study showed that prophylactic low dose of TA did not have a significant effect in the management of intraoperative blood loss and transfusion requirements in children undergoing scoliosis surgery. It is important to emphasize that our study is retrospective and that the size of the sample is small. Further studies are needed to evaluate the efficacy and safety of TA on paediatric scoliosis surgery.

Aplicação da Children's Depression Inventory Numa População Clínica de Adolescentes: Estudo Exploratório

Introdução: A Children’s Depression Inventory (CDI; Kovacs, 1992) é usada para avaliar a existência de sintomatologia depressiva na infância e adolescência e tem sido amplamente aplicada em populações não clínicas, em Portugal, desde a sua validação (Marujo, 1994). Porém, os dados referentes a populações clínicas são escassos. Objectivo: Pretende-se estabelecer correlações clínicas numa amostra de adolescentes seguidos em consulta de Pedopsiquiatria fazendo uma contribuição para a validação da CDI em Portugal, com vista a permitir o alargamento da sua aplicação a populações clínicas. Métodos: A CDI -27 itens foi auto-preenchida na 1ª entrevista de atendimento por 35 adolescentes (F=23; M=12) com necessidade de rastreio de depressão, utentes da Consulta de Ambulatório da Clínica da Juventude entre Janeiro/2010 e Julho/2011. Foram excluídos os casos com processo clínico incompleto. Na estatística usou-se o IBM SPSS 19. Resultados: Os dados correspondem a 7,9% da população de origem (N=443). A idade média foi de 14,5 anos (Mín. =13; Máx. =16). A escolaridade média foi de 8,54 anos (Mín. =5; Máx. =11). A estrutura familiar e motivos de pedido de consulta corresponderam aos estudos anteriores efectuados na Clínica. O cutt-off do nível clínico é 15 e 68,5% da amostra estava acima deste valor. O humor negativo (26%) e sentimento de ineficácia (23%) foram as subescalas mais elevadas; 40% dos jovens pontuou para mais do que uma subescala. Os diagnósticos obtidos foram Perturbações do Humor (43%), Perturbações de Adaptação (17%), Perturbações Disruptivas do Comportamento (14%), Perturbações de Ansiedade (9%), Problemas com Grupo de Apoio Primário (3%), Perturbações de Personalidade (3%), e outros (9%). O qui-quadrado não foi significativo para um cut-off de 15 (considerados Perturbações do Humor e Outros diagnósticos). Conclusões: A CDI e os resultados das subescalas são úteis para uma abordagem focalizada e permitem a priorização de casos. Porém, os resultados obtidos comprometem o uso da CDI na detecção de Perturbações do Humor. Os autores sugerem a realização de mais investigações com o objectivo de alargar e melhorar a avaliação do uso clínico da CDI.

Exercise-Induced Intraventricular Obstruction in a Child with Near Syncope and Chest Pain During Exercise

We report the case of a 10-year-old girl with two episodes of light-headedness and chest pain during exercise. She had an unremarkable clinical record, physical examination, ECG, and echocardiogram. Noninvasive ischemia tests were positive, but coronary angiography was normal. Exercise stress echocardiogram revealed an exercise-induced intra-left-ventricular obstruction with a peak gradient of 78 mmHg and replicated her symptoms. After starting beta-blocker therapy her clinical status improved and no residual obstruction was detected. The authors review this unsuspected clinical condition, seldom reported in the adult population and, to our knowledge, never before in a child.

Fexofenadine is Efficacious and Safe in Children (Aged 6-11 Years) with Seasonal Allergic Rhinitis

Background: This is the first prospective, randomized, doubleblind, placebo-controlled study showing statistical improvement of an H1-antihistamine in children with seasonal allergic rhinitis in all symptoms throughout the entire treatment period. Objective: This randomized, placebo-controlled, parallelgroup,double-blind study was performed to assess the efficacy and safety of fexofenadine in children with seasonal allergic rhinitis. Methods: This study was conducted at 148 centers in 15 countries. Nine hundred thirty-five children (aged 6-11 years) were randomized and treated with either fexofenadine HCl 30 mg (n = 464) or placebo (n = 471) tablets twice a day for 14 days. Individual symptoms (sneezing; rhinorrhea; itchy nose, mouth, throat, and/or ears; itchy, watery, and/or red eyes; and nasal congestion) were assessed at baseline and then daily at 7:00 AM and 7:00 PM (±1 hour) during the double-blind treatment period. Each total symptom score was the sum of all symptoms, excluding nasal congestion. The primary efficacy variable was the change from baseline in the average of the daily 12-hour evening reflective total symptom scores throughout the double-blind treatment. Safety was evaluated from adverse-event reporting, vital signs, physical examinations, and clinical laboratory data at screening and study end point.

Asma de Esforço na Criança - Contributos para a Normalização das Provas de Provocação

A asma induzida pelo exercício (AIE), apesar de entidade muito prevalente na criança asmática,apresenta aspectos etiopatogénicos não totalmente esclarecidos. De igual modo, os aspectos metodológicos das provas de provocação utilizadas para o diagnóstico da AIE não estão normalizados. Objectivos: Foram objectivos deste trabalho estudar sensibilidade e especificidade de diferentes parâmetros funcionais (DEMI vs VEMS) e equipamentos(bicicleta ergométrica vs tapete rolante) utilizados nas provas de esforço, monitorizar a ocorrência de respostas tardias ao esforço e correlacionar os resultados com os de uma prova de provocação brônquica inespecífica normalizada (metacolina). Métodos: Foram incluídas 22 crianças com asma e 10 com rinite (grupo controle), com 7-15 anos. Todas as crianças foram submetidas a três provas de provocação efectuadas no intervalo de 1 mês, provas de esforço em tapete rolante (T) e com bicicleta ergométrica (B) e prova de metacolina, efectuadas sob condições ambientais controladas e com interrupção da medicação relevante. Resultados: Sensibilidade: T - redução VEMS >=10%=82%; B - redução VEMS>=10%=57%; T - redução DEMI>=10%=86%; B - redução DEMI >=10%=81%. Especificidade: T & B - redução VEMS >=10%=100%; T - redução DEMI>=10%=40%; B - redução DEMI>=10%=33%. Não se identificaram respostas broncoconstritoras tardias ao exercício. As crianças asmáticas com prova de esforço positiva apresentaram uma reactividade à metacolina significativamente superior à dos asmáticos com prova negativa.Conclusões: A prova de esforço em tapete rolante representa o melhor teste para diagnóstico da AIE na criança. O parâmetro funcional normalizado a ser utilizado deverá ser o VEMS, aceitando-se uma redução de 10% como critério de positividade. Os doentes com resposta positiva ao esforço foram igualmente mais reactivos à prova de metacolina, isto é apresentam hiperreactividade brônquica inespecífica mais grave, o que substancia o interesse da terapêutica preventiva anti-inflamatória com corticóides tópicos e/ou antileucotrienos no controle da AIE.

Methacholine Dose-Response Slopes from Maximal Bronchial Challenge Tests in Asthmatic Children: Methodological Aspects

To determine whether the slope of a maximal bronchial challenge test (in which FEV1 falls by over 50%) could be extrapolated from a standard bronchial challenge test (in which FEV1 falls up to 20%), 14 asthmatic children performed a single maximal bronchial challenge test with methacholin(dose range: 0.097–30.08 umol) by the dosimeter method. Maximal dose-response curves were included according to the following criteria: (1) at least one more dose beyond a FEV1 ù 20%; and (2) a MFEV1 ù 50%. PD20 FEV1 was calculated, and the slopes of the early part of the dose-response curve (standard dose-response slopes) and of the entire curve (maximal dose-response slopes) were calculated by two methods: the two-point slope (DRR) and the least squares method (LSS) in % FEV1 × umol−1. Maximal dose-response slopes were compared with the corresponding standard dose-response slopes by a paired Student’s t test after logarithmic transformation of the data; the goodness of fit of the LSS was also determined. Maximal dose-response slopes were significantly different (p < 0.0001) from those calculated on the early part of the curve: DRR20% (91.2 ± 2.7 FEV1% z umol−1)was 2.88 times higher than DRR50% (31.6 ± 3.4 DFEV1% z umol−1), and the LSS20% (89.1 ± 2.8% FEV1 z umol−1) was 3.10 times higher than LSS 50% (28.8 ± 1.5%FEV1 z umol−1). The goodness of fit of LSS 50% was significant in all cases, whereas LSS 20% failed to be significant in one. These results suggest that maximal dose-response slopes cannot be predicted from the data of standard bronchial challenge tests.
