Hígado graso no alcohólico en pacientes con sobrepeso y obesidad infantojuvenil / Non-alcoholic fatty liver in children and adolescents with excess weight and obesity

Fundamentos y objetivo: La esteatosis hepática, también denominada hígado graso no alcohólico (HGNA), es la enfermedad hepática más frecuente en niños obesos y está sufriendo un incremento importante en su incidencia debido al aumento de la obesidad infantil. Los objetivos de nuestro trabajo son: estimar la prevalencia de HGNA en niños con sobrepeso y obesidad utilizando el valor de la glutamate pyruvate transaminase (GPT, «transaminasa glutámico-pirúvica») y la ecografía abdominal, así como correlacionar la presencia de HGNA con distintos parámetros antropométricos y bioquímicos. Pacientes y método: Estudio transversal de prevalencia que incluye pacientes con sobrepeso y obesidad, con edades entre 5 y 15 años, reclutados entre 2004-2012. Las variables independientes incluidas fueron: edad, sexo, peso, talla, índice de masa corporal, perímetro de cintura (PC), índice cintura-talla (ICT), insulinemia,Homeostasis model assessment-insulin resistance (HOMA-R), colesterol total, triglicéridos (TG), high density lipoproteins (HDL, «lipoproteínas de alta densidad»), low density lipoproteins (LDL, «lipoproteínas de baja densidad»), glutamic-oxaloacetic transaminase (GOT, «transaminasa glutámico-oxalacética»), GPT y gamma glutamil transpeptidasa (GGT). Resultados: Se seleccionaron 126 pacientes, con una edad media (DE) de 11,94 (3,12) años. El 19,66% presentó elevación patológica de GPT. Treinta y ocho pacientes (30,15%) presentaron esteatosis hepática utilizando la ecografía abdominal. Los valores de insulinemia, HOMA-R y LDL fueron significativamente mayores en pacientes con alteración de GPT (p = 0,015, p = 0,008 y p = 0,002, respectivamente). Los pacientes con HGNA observado en ecografía también mostraron mayores valores de insulinemia, PC, ICT, colesterol total, TG, LDL, GOT, GPT y GGT que los pacientes con ecografía normal, alcanzándose la significación estadística en valor de insulinemia, HOMA, LDL y GPT. Conclusiones: La esteatosis hepática es un trastorno relativamente frecuente en niños y jóvenes con obesidad. Dos de cada 10 niños –utilizando GPT– y 3 de cada 10 –utilizando la ecografía abdominal– la presentan, y el marcador bioquímico que mejor la define es una elevación de la GPT. Es imprescindible y necesaria una modificación en el estilo de vida que incluya la pérdida de peso como medida principal para evitar complicaciones en la vida adulta (AU)

Basis and objective: Hepatic steatosis, also known as non-alcoholic fatty liver (NAFL), is the most frequent liver disease in obese children. Due to an increase in infantile obesity, it is experiencing a significant increment in incidence. Our objetives are: Estimate the prevalence of NAFL in children with excess weight and obesity using the glutamate pyruvate transaminase (GPT) value as a biochemical test and an abdominal ultrasound, and correlate the presence of hepatic steatosis with various anthropometric and biochemical parameters. Patients and method: Cross-sectional prevalence study which includes children with excess weight and obesity between the ages of 5 and 15 years, between the years 2004-2012. The independent variables included were: age, sex, weight, size, body mass index (BMI), waist circumference (WC), waist size index (WSI), insulinemia, Homeostasis model assessment-insulin resistance (HOMA-R), total cholesterol, triglycerides (TG), high density lipoproteins (HDL), low density lipoproteins (LDL), glutamic-oxaloacetic transaminase (GOT), GPT and gamma-glutamyl transpeptidase (GGT). Results: One hundred and twenty-six patients, with an average age of 11.94 (3.12) years were recruited. A percentage of 19.66 of the patients presented elevated GPT pathology. Of the 126 abdominal ultrasounds performed, 38 patients presented hepatic steatosis (30.15%). The levels of insulinemia, HOMA-R and LDL were significantly higher in patients with altered GPT, compared to those with normal GPT values (P = .015, P = .008 and P = .002, respectively). The patients with an objective HGNA in ultrasound, also showed greater levels of insulinemia, WC, WSI, total cholesterol, TG, LDL, GLT, GPT and GGT than the patients with normal ultrasounds, thereby achieving statistical significance in insulinemia, HOMA-R, LDL and GPT values. Conclusions: NAFL is a relatively frequent disorder in obese children and adolescents. In our study, 2 of 10 children –using GPT– and 3 of every 10 –using abdominal ultrasound– present the same. The biochemical marker which best defines it is an elevation in GPT. A modification in lifestyle which includes weight loss as a principal means of avoiding complications in adult life, is essential and necessary (AU)

Etiopatogenia de la esquizofrenia: el valor de la neurobiología, el neurodesarrollo y la neurodegeneración / Ethiopathogenesis of schizophrenia: the role of neurobiology, neurodevelopment and neurodegeneration

La Esquizofrenia esun síndrome muy complejo y heterogéneo formado por superposición de multitud de fenómenos que coexisten a lo largo de la evolución del proceso morboso en proporción variable. Gran parte de pacientes muestran en el momento de la eclosión de síntomas psicóticos algunos marcadores que hacen pensar que la enfermedad se asienta sobre un sustrato neurobiológico disfuncional (signos físicos y neurológicos menores, hallazgos en neuroimagen). La hipótesis del neurodesarrollo trata de explicar el modo en que algunos factores tempranos dañinos indicirían sobre los procesos del desarrollo cerebral normal (neurogénesis, proliferación neuronal, migración y establecimiento de redes neurales), generando cambios orgánicos duraderos capaces de justificar la clínica de los pacientes. Existen todavía grandes interrogantes acerca de la sensibilidad, especificidad, y valor predictivo de los marcadores biológicos, así como de su utilidad en prevención y detección precoz de casos. Sin embargo, algunos pacientes parcen sufrir un curso deteriorante después de la aparición de las primeras manifestaciones clínicas. La hipótesis neurodegenerativa aboga por la existencia de fenómenos patológicos de aparición más tardía y carácter progresivo, y que serían responsables de la progresión de algunas variables clínicas y de neuroimagen. El glutamato parece estar presente a lo largo de los procesos de desarrollo normal, y maduración cerebral postnatal, y posiblemente en la etiopatogenia de la esquizofrenia (AU)

[Depressive pseudodementia: Diagnostic frontiers]. / Pseudodemencia depresiva: fronteras diagnósticas.

In the limits between dementia and depression we find a clinical entity in permanent controversy; Depressive Pseudodementia. Depressive pseudodementia is defended by some authors and criticised by others and set us in the diagnostic frontier palced between the cognitive and the affective, between neurology and psychiatry. The entity is not well delimited and reaches diagnostic relevance clinical, evolution and response aspects. In the present issue, we realize a reflection on the term depressive pseudodementia with a review of the scientific literature with special attention in clinical and diagnostic subjets. We conclude that depressive pseudodementia although considering diagnostic limitations is still a valid term in clinical practice, and it eases the approximation, diagnosis and treatment of patients with mixed symptoms of cognitive and depressive type.

Pseudodemencia depresiva: fronteras diagnósticas / Depressive pseudodementia: diagnostic frontiers

En los límites que separan la demencia de la depresión nos encontramos con una entidad permanentemente sujeta a controversia: la pseudodemencia depresiva. Defendida por unos autores y criticada por otros, nos sitúa en la frontera diagnóstica existente entre lo cognitivo y lo afectivo, entre la Neurología y la Psiquiatría, entidad no bien delimitada donde alcanzan relevancia diagnóstica tanto aspectos clínicos como evolutivos y de respuesta a tratamiento. Realizamos una reflexión sobre el término de pseudodemencia depresiva revisando la literatura científica, prestando atención especial a aspectos clínicos y diagnósticos. Concluimos que la pseudodemencia depresiva, a pesar de las opiniones en contra y limitaciones diagnósticas, continúa siendo un término válido en el ejercicio de la práctica clínica, que facilita la aproximación, diagnóstico y tratamiento de los pacientes que manifiestan sintomatología mixta; afectiva y cognitiva.

[A prospective study of patient with schizophreniform disorder: a nosological dilemma?]. / Un estudio prospectivo de pacientes con trastorno esquizofreniforme: dilema nosológico?

We study retrospectively 42 inpatients of the psychiatry department of the Ramón y Cajal Hospital, through a period between 1st January of 1988 and the 31st December 1993. All of them were diagnosed at discharge of schizophreniform disorder according to DSM-III R diagnostic criteria and it was in all of them the index episode of the psychosis. Sociodemographic, clinical, evolutive, and therapeutical variables are analyzed. We made a new assessment of the patients in the sample during April 1994 through a direct interview. The mean follow-up period was 4.18 years. The main results were: A predominance of male/female proportion (2/1), nearly half of the sample had emotional or psychosocial stressors previous to the episode. Previous schizoid personality traits were found in 57.1%. 11.9% had first degree relatives antecedents of schizophrenia and 19% of non-bipolar affective disorders. At follow-up 40.4% needed to be hospitalized again. It is noteworthy that 80.9% were rediagnosed during follow-up as schizophrenia.

[Progress and therapeutic response in the obsessive-compulsive disorder]. / Evolución y respuesta terapéutica en el trastorno obsesivo-compulsivo.

The purpose of the present work was to analyze the outcome of patients diagnosed of Obsessive Compulsive Disorder (OCD) after Hospital discharge from our Unit, focusing on therapeutical efficacy immediately after discharge and in the follow up, searching for good evolution predictors. We have studied 42 patients (26 females and 16 males) diagnosed of OCD according to ICD-9 diagnostic criteria, all patients were hospitalized during a seven years period 1981 and 1988. Therapeutical response was evaluated through a (1-4 punctuation) of a Clinical Global Impression Scale considering the changes from the moment the patient was hospitalized, the day of discharge and in the follow up (mean 4.1 years). 73.8% and 71.4% were considered as treatment "responders" the day discharged and in the follow up respectively. Through a multiple logistic regression, treatment with serotonergic drugs and insidious onset of the illness were identified as short-term treatment response predictors, while the absence of a previous obsessive personality was a long-term therapeutical response predictor. Our results show the efficacy of serotonergic drugs and the tact that the presence of a previous obsessive personality could have a prognostic value in OCD.

[Psychopharmacologic treatment of bulimia nervosa]. / Tratamiento psicofarmacológico de la bulimia nerviosa.

Since the inclusion of Bulimia Nervosa (BN) in DSM-III as a nosological entity, it has been a focus of attention in the literature. To the present day several therapeutical approaches have been developed, pharmacological, psychological either separated or combined with diverse results. We have studied 20 patients diagnosed of BN according to DSM-III-R diagnostic criteria, from a psychopathological, and evolution point of view, the therapeutical response to a fixed daily dose of Fluoxetine 80 mg., during three months, with evaluations on days: 0-14-30-90. The mean age of the sample was 19.5 years; in 70% at the onset of the illness the Anorexia Nervosa symptomatology was prominent; there was a predominance of affective-obsessive previous personality traits in 60%, 100% showed unsatisfied or altered body image. We want to point out the quick improvement of various parameters such as: the constant eating desire, the binge eating episodes, the vomiting, the misuse of laxatives and the affective and anxious symptomatology. We compare our results with previous studies and make a review of the literature on this topic, we also give an efficacy profile of the different psychopharmacological drugs used in the treatment of eating disorders and a clinical guide to identify those patients who could improve with a psychopharmacological treatment.
