Sintomatología del trastorno por déficit de atención con hiperactividad y su relación con el maltrato infantil: predictor y consecuencia

The current literature increasingly associates the presence of symptoms of ADHD in both physical and psychological and sexual child abuse. This implies the need for greater accuracy in the differential diagnosis, as until a few years ago, post-traumatic stress disorder was considered the reference symptoms for this type of case. Thus, it is necessary to define and conceptualize an increasingly broad and detailed world of sequels and consequences, where ADHD may be related to the psychological damage suffered by child abuse. Furthermore, the particular vulnerability of children with ADHD can, in turn, become a factor of risk that needs to be considered by the professionals who care for this type of patient.     

Metilfenidato en el tratamiento del trastorno de déficit de atención con hiperactividad en pediatría: monitorización en matrices biológicas

Attention-deficit hyperactivity disorder (ADHD) has emerged in the last few years as the most commonly diagnosed and treated psychiatric disorder in the paediatric population. In 1980's, methylphenidate (MFD) a psychomotor stimulant drug, was approved in Spain for the symptomatic therapy of ADHD. Since then, MFD has become one of the most extensively prescribed and studied treatment for ADHD both in children and adults.In this paper, the main pharmacological issues of MFD are reviewed, focusing on its pharmacokinetics in conventional (blood and urine) and non-conventional (hair, oral fluid and sweat) biological matrices, its pharmaceutical preparations, therapeutic levels and side effects.     

Optimización del tratamiento con azatioprina: determinación de la actividad de tiopurina metiltransferasa y las concentraciones de metabolitos tiopurínicos

IntroductionIndividualised doses of azathioprine (AZA) may be prescribed by monitoring the levels of the enzyme thiopurine methyltransferase (TPMT). The measurements of thiopurine metabolites of AZA, 6-thioguanine (6-TGN) and 6-methylmercaptopurine (6-MMP), have also been reported as new markers of AZA activity.ObjectivesTo describe TPMT phenotype in our population and to establish a relationship between thiopurine metabolites,and therapeutic activity and adverse effects.Material and methodsData on TPMT were retrospectively collected from 107 patients, and 6-TGN and 6-MMP levels in 18 patients currently on treatment with AZA (Crohn's disease 5, ulcerative colitis 5, autoimmune hepatitis 5).ResultsMean value of TPMT was 20.19 U/ml. None of the patients had a TPMT activity<5 U/ml. Of the 18 patients on treatment, 13 showed sub-therapeutic levels of 6-TGN (<235 pmol/8×10⁸ red blood cells). Clinical remission was maintained in 45% of patients. Mean levels of 6-TGN in patients with clinical remission were 259 pmol/8×10⁸ red blood cells versus 209 pmol/8×10⁸ red blood cells in non-responders (p=0.37). There was an inverse relationship (r=?0.28) between TPMT and 6-TGN levels. Toxic effects occurred in 6 of 18 patients, with leukopenia in 5 and hyperamylasemia in 1.ConclusionsDetermination of TPMT and monitoring of thiopurine metabolites allows AZA treatment to be optimised, although further studies are necessary to establish therapeutic effectiveness and toxicity ranges.     

Utilidad de la ecografía comparada con la capnografía y la radiografía en la intubación traqueal

ObjectivesThe aim of this study was to assess the usefulness of bedside ultrasound compared to capnography and X-ray for endotracheal intubation in children and newborns.Materials and methodsHemodynamically stable children intubated in pedriatric and neonatal intensive care unit were included. Endotracheal tube insertion was checked after every intubation attempt by tracheal ultrasound and capnography simultaneously. The endotracheal tube insertion depth was then checked by assesment of lung sliding by thoracic ultrasound. Thereafter, Chest X-ray was performed and interpreted as usual. Time to perform each technique was recorded.ResultsThe study included 31 intubations in 26 patients (15 in PICU and 16 in NICU). There were no statistically significant differences between tracheal ultrasound and capnography or between thoracic ultrasound and x-ray in identifying the correct endotracheal intubation and assessment of endotracheal tube insertion depth, respectively. Sensibility and specificity of ultrasound compared to capnography was 92% and 100%, and 100% and 75% compared to X-ray. Ultrasound was significantly slower compared to capnography [12 (4-16) vs 6 (3-12) seconds; P<.001] and significantly quicker compared to X-ray [0.22 (0.17-0.40) vs. 20 (17-25) minutes, P<.001].ConclusionsUltrasound appears to be as effective as capnography, although slower, for identifying endotracheal intubation. Ultrasound may be useful in clinical situations, such as cardiopulmonary resuscitation where capnography is less reliable. Ultrasound is as effective and quicker than X-ray for assessment of endotracheal tube insertion depth, and it may contribute to decrease the routine use of X-ray after tracheal intubation.     

Recomendaciones de seguimiento del prematuro tardío

The population of late preterm infants (PT), those born between 34 + 0 and 36 + 6 weeks of gestation, accounts for 70-74% of all premature infants, and is not specifically included in most of the follow-up protocols for preterm infants. For many years, PTs have been handled as if they were term newborns, which has led to a limited knowledge of their outcome in the medium and long term. Their neonatal morbidity is associated with a higher incidence of postnatal complications, with an increased rate of hospital re-admissions due to malnutrition, hyperbilirubinaemia, and respiratory problems, when compared to term infants. Cerebral immaturity may be the main cause of the deficits observed in the long-term neurodevelopment of this population, making them more vulnerable. Several issues have been described, such as delays or disabilities in the pre-school stage, cerebral palsy, mental retardation, intellectual disability, schizophrenia, and psychological development of behavioural and emotional disorders.The SEN34-36 Group of the Spanish Society of Neonatology, in collaboration with the Spanish Association of Primary Care Paediatrics, have developed these follow-up recommendations with the main objective of reducing the impact of prematurity on PT development. The secondary objectives of the document are to make neonatologists and paediatricians aware of the risks of sequelae of PTs, to determine and unify the evaluations and / or interventions that should be carried out, to offer clinical follow-up tools for the early detection of developmental delays, and to coordinate the care by all the professionals involved.     

Evaluación de la comorbilidad y la ansiedad social en adolescentes con trastorno por déficit de atención con hiperactividad: Estudio SELFIE

IntroductionAttention-deficit/hyperactivity disorder (ADHD) and its comorbidities have an impact on the social anxiety of children and adolescents, but there are practically no studies addressing this topic in adolescence. Our objective was to assess the degree of social anxiety and to analyse the presence of psychiatric comorbidities (PSCs) in adolescents with ADHD.MethodologyWe conducted a cross-sectional observational study in patients aged 12 to 18 years with a confirmed diagnosis of ADHD (DSM-5). We collected data on the presence and type of PSCs and assessed social anxiety by means of the Social Anxiety Scale for Adolescents (SAS-A).ResultsForty-six child and adolescent psychiatrists and paediatric neurologists participated in the study and recruited 234 patients. Of the total patients, 68.8% (159) were male and 31.2% (72) female, with a mean age in the sample of 14.9 years (95% CI, 14.6-15.1). The type of ADHD was combined type (C) in 51.7% (121), predominantly inattentive (PI) in 37.2% (87), and predominantly hyperactive-impulsive (PH) in 9% (21). Of all patients, 97.9% (229) received pharmacological therapy: 78.6% (184) methylphenidate, 15% (35) lisdexamfetamine and 4.3% (10) atomoxetine.We found PSCs in 50.4% of the patients (118), of which the most frequent were learning and communication disorders (20.1%, n = 47) and anxiety disorders (19.2%, n = 45). The patients scored significantly higher in the SAS-A compared to reference values in the healthy population. The scores in the SAS-A were less favourable in adolescents with the PI type compared to those with the PH type (P = .015). The presence of a comorbid anxiety disorder was associated with worst scores in SAS-A (P < .001) showing an increased social anxiety.ConclusionAdolescents with ADHD classified as PI and those with comorbid anxiety had a higher degree of social anxiety as measured by the SAS-A. This psychological aspect must be identified and controlled in adolescents with ADHD to promote their social adaptation.
