Tiempo y uso de pantallas en niños y adolescentes: revisión y comparación de las guías de cinco instituciones sanitarias / Time and use of screens in children and adolescents: a review and comparison of the guidelines of five health care institutions

Fundamentos y objetivo. El tiempo de pantalla es una actividad muy frecuente entre las rutinas de los más jóvenes. Por ello han sido varias las instituciones que han propuesto pautas sobre un tiempo de pantalla saludable en la población pediátrica, aunque existen controversias entre ellas. El objetivo de este trabajo es revisar y comparar las principales recomendaciones de cinco instituciones sanitarias sobre el uso y tiempo de pantalla para la población infantil y adolescente. Métodos. Se revisaron y compararon las guías sobre el tiempo y uso de pantallas propuestas por cinco instituciones sanitarias: Ministerio de Sanidad, Servicios Sociales e Igualdad, Organización Mundial de la Salud, la Academia Americana de Pediatría, la Sociedad Canadiense de Pediatría Resultados. Las guías se basaban en la duración frente a las pantallas. Existía unanimidad respecto a los más pequeños (0-5 años), sin embargo, estas pautas no fueron tan claras para los niños de edad escolar y adolescentes. Conclusiones. Las guías deberían incluir otros aspectos importantes sobre el uso de pantallas, como recomendaciones diferenciando entre dispositivo, sobre el uso de pantallas para fines educativos o tener en cuenta el tiempo de pantalla no sedentario. Además, las futuras actualizaciones de las guías deberían incluir recomendaciones para todos los agentes involucrados en la salud y el desarrollo de los niños y adolescentes (AU)

Background and objective. Screen time is a common activity among the routines of the youngest. Thus, some institutions have proposed guidelines on healthy screen time in the paediatric population, although there are controversies between them. The aim of this work is to revise and to compare the main recommendations of five health institutions about screen time and usage of screens in children and adolescent population (up to 19 years old). Methods. We revised and compared guidelines about screen time and usage of screens purposed for five health institutions: Ministerio de Sanidad, Servicios Sociales e Igualdad, World Health Organization, American Academy of Pediatrics, Canadian Pediatric Society, and Government of Australia Results. Guidelines were based on the duration in front of screens. Guidelines unanimously agreed on the limitation of time and use among the youngest children (0-5 years), however, these recommendations were not as clear cut for those school-aged children and adolescents. Conclusions. Guidelines should include other important aspects on usage of screens as recommendations differentiating between devices, about educational screen time or taking (AU)

Hipotiroidismo adulto en una zona básica de salud / Hypothyroidism in adults in a basic health area

Introducción. El objetivo del presente trabajo es estudiar la prevalencia y las características clínicas y epidemiológicas de la enfermedad hipotiroidea en el adulto, a través del registro de datos electrónicos de la historia clínica. Material y métodos. Estudio observacional, descriptivo y transversal. La población diana eran los pacientes de los centros de salud de Lucena I y II (Córdoba). Criterios de inclusión: pacientes que tuvieran 14 años o más, diagnosticados de hipotiroidismo, nacidos y con residencia en Lucena. Se seleccionaron 214 pacientes a través de un muestreo aleatorio, los cuales se sometieron a una entrevista clínica mediante un cuestionario. Resultados. La edad media de los pacientes fue de 49,71 años (DT 17,03; IC 95% 47,34-51,98), siendo el 85,5% mujeres. El 74,8% son diagnosticados de hipotiroidismo subclínico frente al 18,7% de hipotiroidismo primario y un 6,5% de hipotiroidismo secundario. El 53,7% (IC 95% 46,81-60,59) de los pacientes diagnosticados de hipotiroidismo no tienen pedidos los anticuerpos tiroideos; sin embargo, un 75,2% (IC 95% 68,89-80,86) están recibiendo tratamiento con levotiroxina. La prevalencia de hipotiroidismo fue de un 5,7% (IC 95% 5,46-5,96). Conclusiones. El hipotiroidismo subclínico es muy frecuente en las consultas de Atención Primaria. Muchos pacientes no están correctamente diagnosticados y otros están sobremedicados, por lo que sería preciso revisar el diagnóstico

Introduction. The objective of the present study is to study the prevalence, as well as the clinical and epidemiological characteristics of hypothyroid disease in adults using the computerised clinical records. Material and methods. Observational, descriptive and cross-sectional study. The target population was the patients of the health centres of Lucena I and II (Córdoba). Inclusion criteria: Patients 14 years or older, diagnosed with hypothyroidism, born and resident in Lucena. Two hundred and fourteen patients were recruited by random sampling, who then underwent a clinical interview using a questionnaire. Results. The mean age of the patients was 49.71 years (SD 17.03; 95% CI 47.34-51.98), with 85.5% women. A diagnosis of sub-clinical hypothyroidism was found in 74.8%, compared to 18.7% of primary hypothyroidism, and 6.5% of secondary hypothyroidism. The 53.7% (95% CI 46.81-60.59) of patients diagnosed with hypothyroidism did not have thyroid antibodies results. However, 75.2% (95% CI 68.89-80.86) were being treated with levothyroxine. The prevalence of hypothyroidism was 5.7% (95% CI 5.46-5.96). Conclusions. Sub-clinical hypothyroidism is very common in Primary Care clinics. Many patients are not correctly diagnosed and many are over-medicated, suggesting a need to review the diagnosis

Fundamentos de la intervención temprana en niños con trastornos del espectro autista / Basics of early intervention in children with autism spectrum disorders

Los trastornos del espectro autista (TEA) consisten en una diada caracterizada por deficiencias en la comunicación e interacción social y patrones restrictivos y repetitivos de comportamiento. En conjunto tienen una prevalencia del 0,6% en la población general, aunque no se cuenta con estadísticas nacionales. Si bien la evolución es variable, se ha visto que la intervención temprana es un factor importante en la determinación del pronóstico. El objetivo del presente trabajo ha sido actualizar conceptos respecto a la evidencia actual disponible sobre la relevancia de intervenir tempranamente este tipo de trastornos. Con el análisis de la información recopilada se confirma la importancia de la intervención temprana en niños con TEA, como así también, el rol de pediatras y otros profesionales de la salud en la detección precoz de estos trastornos.

Autism Spectrum Disorders (ASD) are characterized by impairments in communication and social interaction, as well as restricted and repetitive patterns of behavior. They have a prevalence of 0.6% in the general population, although there are no national statistics. Even though their evolution is variable, it has been observed that early intervention is an important factor determining prognosis. The aim of this study is to update concepts regarding the current available evidence on the importance of early intervention. After analyzing the collected information, the importance of early intervention programs for children with ASD is confirmed, as well as the role of pediatricians and other health professionals in the early detection of these disorders.

Diagnostic yield of 335 push video-enteroscopies.

BACKGROUND AND OBJECTIVES: The diagnostic yield of push enteroscopy (PE) varies widely from 13 to 78% of cases, according to the various series. The aim of this retrospective cohort study was to determine the endoscopic and histological yield of PE in our health area. PATIENTS AND METHODS: A total of 355 consecutive patients (190 males/165 females; mean age 45 years, range 15-89) underwent PE over a 6-year period, from 1997 to 2003. PE was performed under sedation and without overtube. Small-bowel mucosa biopsies were taken in 199 explorations (56%). Clinical indications for PE included: chronic diarrhea (35%), occult digestive bleeding (ODB) or iron-deficiency anemia (28%), suspected small-bowel malignancy (16%), chronic abdominal pain (28/355; 8%), follow-up of polyposis or malabsorption syndromes (7%), and abnormal radiographic findings (6%). RESULTS: PE detected lesions in 122 cases (34%); in 6 cases (6%) lesions were within the reach of esophagogastroduodenoscopy. A normal macroscopic appearance of the small intestinal mucosa with an abnormal histological study was seen in 16 patients (6%). Major findings included: malabsorptive diseases (14%), nonspecific enteropathy (5%), angiodysplasia (3,5%), lymphangiectasia (3%); jejunal polyps (2%), Crohn s disease (2%), intestinal tumors (2%), extrinsic jejunal strictures (0.5%), and other (10/355; 3%). Abnormal radiographic findings (62%), chronic diarrhea (37%) and ODB (31%) were the indications with a higher diagnostic yield. No major complications were seen. CONCLUSIONS: According to our experience, PE is a safe and useful tool for the evaluation of small-bowel disease, especially in some indications (abnormal radiographic findings, chronic diarrhea, and ODB). Small-bowel biopsy increases PE's diagnostic yield in patients with chronic diarrhea.

Rendimiento diagnóstico de 355 videoenteroscopias por pulsión / Diagnostic yield of 335 push video-enteroscopies

Introducción y objetivos: el rendimiento diagnóstico de la enteroscopia por pulsión (EP) varía ampliamente (13-78%) según las series. El objetivo de este estudio retrospectivo fue determinar el rendimiento endoscópico e histológico de la EP en nuestra área sanitaria. Pacientes y métodos: un total de 355 pacientes consecutivos (190 hombres/165 mujeres; media de edad 45 años, rango 15-89), fueron sometidos a EP en un periodo de 6 años, entre 1997 y 2003. Las EP fueron realizadas bajo sedación y sin sobretubo, tomándose biopsias de la mucosa de intestino delgado en 199 exploraciones (56%). Las indicaciones clínicas fueron: diarrea crónica (126/355; 35%), hemorragia digestiva de origen oscuro o anemia ferropénica (99/355; 28%), sospecha de tumor intestinal (56/355; 16%), dolor abdominal crónico (28/355; 8%), seguimiento de síndromes de poliposis o cuadros malabsortivos (25/355; 7%), y confirmación de anormalidades radiográficas (21/355; 6%). Resultados: la EP identificó lesiones en 122 pacientes (34%), observándose lesiones al alcance del gastroscopio convencional en 6 casos (6%). En 16 pacientes (6%) el aspecto macroscópico de la mucosa intestinal fue normal, objetivándose hallazgos diagnósticos en el estudio histológico. Los principales hallazgos encontrados fueron: proceso malabsortivo (50/355; 14%), enteropatía inespecífica (19/355, 5%), angiodisplasia (13/355; 3,5%), linfangiectasia (10/355; 3%), pólipos yeyunales (6/355; 2%), enfermedad de Crohn (6/355; 2%), tumor intestinal (6/355; 2%), estenosis intestinal extrínseca (2/355; 0,5%), y otros (10/355; 3%). Las indicaciones con mayor rendimiento diagnóstico fueron: confirmación de anormalidades radiográficas (13/21; 62%), diarrea crónica (46/126; 37%), y hemorragia digestiva de origen oscuro (31/99; 31%). No se objetivaron complicaciones graves. Conclusiones: según nuestra experiencia, la EP es una técnica segura y útil para la evaluación de las patologías del intestino delgado, especialmente en ciertas indicaciones (anormalidades radiográficas, diarrea crónica, y hemorragia digestiva de origen oscuro). La biopsia intestinal aumenta el rendimiento diagnóstico de la EP en pacientes con diarrea crónica

A simplified method to quantitate atherosclerosis in the rabbit aorta.

A simple method to quantitatively evaluate atherosclerosis in the rabbit aorta by measuring macroscopic lesion areas (%) was attempted in the present study. Ten female New Zealand white rabbits were fed on a cholesterol-rich diet (5/1000 g of food) during 4 months. Five of them were oophorectomized at the beginning and all were sacrificed at the end. Total levels of cholesterol increased from 50.7+/-14.7 mg/dl to 782.8+/-296.0. No significant differences were observed between oophorectomized and intact rabbits. At 4 months, the cholesterol-rich diet caused in both, intact and oophorectomized rabbits, atherosclerotic lesions affecting 17 and 46% of the aortic surface, respectively. This method may be more practical, easy and useful for quantitative evaluation of aortic atherosclerosis in a large number of rabbits, than histological observations of serial sections of rabbit's aortas.

Transdermal estrogens do not appear to modify the extent of lesional areas of aortic atherosclerosis in oophorectomized rabbits on a cholesterol-rich diet.

Cardiovascular disease (CVD) is the leading cause of death in older women in industrialised countries. It has been suggested that it is the cessation of estrogen production by the ovaries that puts postmenopausal women at increased risk of CVD. Estrogen therapy has demonstrated a protective effect against CVD and several reports suggest that diverse mechanisms may be involved. Oral estrogen appears to be associated with a better lipid profile than the use of transdermal estrogens; however, it is assumed that estrogens, oral and non-oral, have direct actions on the blood vessels that may exert an important role in cardiovascular disease prevention. To investigate the effect of transdermal estrogen therapy on aorta atherogenesis, we studied 20 cholesterol-fed New Zealand White rabbits for 4 months. The rabbits were oophorectomized and randomly assigned to two groups. Ten rabbits underwent bilateral ovariectomy followed by treatment with transdermal 17-beta-estradiol (group E) and the other 10 received placebo after sterilization (Group C). After diet total levels of cholesterol increase in group C from 50. 0+/-12.5 to 820.9+/-186.0 mg/dl, and in group E from 52.6+/-9.4 to 811.4+/-213.0 mg/dl (no significant differences were observed between groups). Estrogen therapy increased twofold the total reactive antioxidant potential (TRAP group C: 22.5+/-16.7 mmol of Trolox/l vs. TRAP group E: 43.4+/-22.4 mmol of Trolox/l; P<0.04). At 4 months, the cholesterol-rich diet caused atherosclerotic lesions in both treated and untreated rabbits affecting 18.7+/-14.5 and 21. 6+/-9.7% of the aortic surface respectively. In summary, the principal result from this study was that although treatment with transdermal 17-beta-estradiol in cholesterol-fed ovariectomized rabbits increases the TRAP to pre-surgery values, it does not inhibit aortic cholesterol accumulation.

[Systemic mastocytosis: clinical case]. / Mastocitosis sistémica: caso clínico.

We report a 38 years old female who, since her childhood, had a history of precisely limited, fixed maculo papular dark brown cutaneous lesions in the trunk and extremities. These lesions become erythematous or urticarial after rubbing, medication intake or scratching. She also had frequent episodes of tachycardia, flushing, headache, abdominal pain, arthralgia, diarrhea and vomiting. She was hospitalized in three occasions due to high frequency tachycardia, hypotension, generalized urticarial erythema and clouding of consciousness. Three of these episodes occurred after the ingestion of antiinflammatory drugs or acetylsalicylic acid. Mastocyte infiltration was confirmed in skin and bone marrow biopsies and in bone scintiscan. The use of H1, H2 blockers and mastocyte stabilizers gave partial relief to the patient.

[Infective endocarditis: clinical aspects and necropsy study in 20 cases]. / Endocarditis infecciosa: aspectos clínicos y estudio necropsico en 20 casos.

Aiming to know the principal anatomo-pathological findings in patients that died with a diagnosis of infective endocarditis, the clinical histories and necropsy protocols of such patients that died between 1984 and 1989 were reviewed. Twenty patients (11 male) aged 43.2 +/- 16.1 years were studied. In nine, the endocarditis was subacute, and 80% had a history of valvular or congenital heart disease. The principal clinical complication was sepsis followed by neurological, nephrological and cardiac complications. The necropsy disclosed cardiac, nephrological and abdominal lesions in 100, 80 and 65% of patients respectively. In 65% of necropsies, neurological injuries were found (cerebral edema in 7 patients and hemorrhagic complications in 11). It is concluded that extra cardiac lesions are frequent in patients dying with a diagnosis of infective endocarditis.
