Health‐related quality of life (HRQL) is used in the assessment of chronic illness. Regarding HIV infection, HRQL assessment is an objective for physicians and institutions since antiretroviral treatment delays HIV clinical progression. The aim of this study was to determine the factors with the most influence on HRQL in HIV‐infected people and to create a predictive model.

A review on the etiological profile of urinary tract infections in childhood and the sensitivity pattern of urinary pathogens in Spain is presented. Escherichia coli continues to be the main etiological agent of urinary tract infection in childhood. Consequently, its sensitivity pattern will usually determine the choice of empirical therapy. The predominance of E. coli is reduced in certain circumstances, in which the presence of other microorganisms is increased. However, the clinical information available at diagnosis does not allow accurate identification of the etiology; only staining and microscopic urine examination can help in treatment selection. In Spain, E. coli presents a high percentage of resistance to ampicillin and cotrimoxazole, whereas second- and third-generation cephalosporins, fosfomycin, aminoglycosides and amoxicillin-clavulanate maintain high sensitivity. In some areas, amoxicillin-clavulanate and first-generation cephalosporins show high levels of resistance, which can limit their empirical use.

Objective: The aim of our study was to investigate the role of Trp64Arg polymorphism of the beta 3-adrenergic receptor (beta 3-AR) gene on metabolic changes and weight loss secondary to a high monounsaturated fat versus a high polyunsaturated fat hypocaloric diet in obese subjects. Material and Methods: A population of 260 obese subjects was analyzed. In the basal visit, patients were randomly allocated for 3 months to either diet M (high monounsaturated fat hypocaloric diet) or diet P (high polyunsaturated fat hypocaloric diet). Results: There were no significant differences between the positive effects (on weight, body mass index, waist circumference, fat mass) in either genotype group with both diets. With diet P and in genotype Trp64Trp, glucose levels (-6.7 ± 12.1 vs. -1.2 ± 2.2 mg/dl; p < 0.05), total cholesterol (-11.2 ± 8.1 vs. -1.0 ± 7.1 mg/dl; p < 0.05), low-density lipoprotein (LDL) cholesterol (-9.7 ± 10.1 vs. -2.2 ± 8.1 mg/dl; p < 0.05), triglycerides (-11.7 ± 13.1 vs. +1.7 ± 10.3 mg/dl; p < 0.05), homeostasis model assessment for insulin resistance (HOMA-R; -0.7 ± 1.1 vs. -0.3 ± 2.1 units; p < 0.05) and insulin levels (-1.8 ± 4.6 vs. -1.0 ± 9.1 mIU/l; p < 0.05) decreased. Conclusion: The metabolic effect of weight reduction by the two hypocaloric diets is greatest in subjects with the normal homozygous beta 3-AR gene. Improvements in total cholesterol, LDL cholesterol, triglyceride, glucose, insulin and HOMA-R levels were better than in the heterozygous group.

Objetivos Comparar la prescripcion de antibioticos sistemicos en la poblacion pediatrica de Castilla y Leon teniendo en cuenta su procedencia: urbana o rural. Material y metodos Los datos del consumo extrahospitalario de antibioticos en la poblacion pediatrica procedieron de la base de datos que procesa los antibioticos facturados en el Servicio de Salud de Castilla y Leon. Estos datos fueron analizados de acuerdo con la ATC (Anatomical Therapeutic Chemical Classification System), expresando los resultados en dosis diaria definida (DDD) por mil habitantes por dia (DHD). Resultados El consumo global de antibioticos en la poblacion pediatrica de Castilla y Leon fue notablemente mas elevado en el medio rural (24,37 DHD en el medio rural frente a 19,54 DHD en el medio urbano). La evolucion interanual fue similar en ambos entornos con un pico de prescripcion en el ano 2003. En el analisis cualitativo, se observa que la mayor prescripcion de antibioticos en el medio rural se hizo principalmente a expensas de amoxicilina y en menor medida por cefixima y azitromicina. Las diferencias de prescripcion en los ambitos urbano y rural de las distintas Areas de Salud fueron variables, destacando las mas grandes de Segovia. Conclusiones Existe gran variabilidad cuantitativa y cualitativa de prescripcion de antibioticos entre las diferentes Zonas Basicas de Salud urbanas y rurales. Pese a sospechar una infravaloracion de los resultados en el medio urbano debido a la utilizacion excesiva de los servicios de urgencias, son precisos estudios mas detallados para comprender mejor los factores determinantes del consumo de antibioticos en ninos.

Los virus se situan en un lugar preferente entre los agentes causales de diarrea aguda, en particular en la infancia. En este contexto el papel de los astrovirus, coronavirus, torovirus y picobirnavirus es emergente. Los astrovirus se han detectado en las heces entre el 1,2 y el 20 % de ninos con diarrea que requieren atencion medica en una gran variedad de localizaciones geograficas. Se han descrito brotes epidemicos en escuelas, guarderias y salas pediatricas, y son mas frecuentes entre ninos de menos de 3 anos. En climas templados se ha demostrado una mayor incidencia invernal, y en climas tropicales esta es similar en todo el ano, siendo su transmision preferente por via orofecal. Se han reconocido siete serotipos de astrovirus humanos, de los cuales el mas comun es el uno. Los viriones pueden eliminarse durante amplios periodos y detectarse mediante microscopia electronica. En estudios epidemiologicos se emplean tecnicas de enzimoinmunoanalisis para detectar el antigeno comun de grupo y se han desarrollado tambien tecnicas basadas en la deteccion de acidos nucleicos mediante hibridacion y amplificacion (reaccion en cadena de la polimerasa). Los coronavirus entericos se han asociado con frecuencia con enfermedad gastrointestinal en recien nacidos y ninos menores de 12 anos. El papel de los torovirus y picobirnavirus como causa de gastroenteritis es tambien emergente. Se necesitan estudios epidemiologicos para determinar su verdadera frecuencia en la comunidad, identificar sus mecanismos de transmision y explicar la fisiopatologia de los cuadros provocados por estos agentes.

Se necesitan estudios epidemiológicos para determinar su verdadera frecuencia en la comunidad, identificar sus mecanismos de transmisión y explicar la fisiopatología de los cuadros provocados por estos agentes. Viral agents are one of the main causes of acute diarrhea, particularly in infants and young children. Astrovirus, coronavirus, torovirus, and picobirnavirus are increasingly being identified as causative agents of gastroenteritis. Astroviruses have been detected in the stools of between 1.2 % and 20 % of children with diarrhea requiring medical care in a variety of geographical areas. Outbreaks have been described in schools, day care settings and pediatric wards. Children younger than 3 years old are the most frequently affected. In temperate climates incidence is greater in winter whereas in tropical areas infection occurs throughout the year. Transmission is mainly through the fecal-oral route. At least seven serotypes of human astroviruses have been recognized and serotype 1 is more common than the other serotypes. Astroviruses are often shed in stools during long periods and can be detected by electron microscopy. An enzyme-immunoassay technique that detects the astrovirus group antigen has been widely used in epidemiological studies. Nucleic acid hybridization and polymerase chain reaction-based techniques have also been used. Enteric coronaviruses have most frequently been associated with gastrointestinal disease in neonates and children younger than 12 years old. The role of toroviruses and picobirnaviruses as causative agents of gastroenteritis is still emerging. Further epidemiological studies to determine the frequency of these viruses in the community and to identify their mechanisms of transmission are needed, as are further studies to elucidate the pathophysiology of diseases due to these agents.

Objetivos Analizar la evolucion de la utilizacion de antibioticos en la poblacion pediatrica, durante los ultimos 5 anos en la Comunidad Autonoma de Castilla y Leon. Material y metodos Se procesaron los antibioticos prescritos a la poblacion pediatrica en el ambito extrahospitalario, utilizando la base de datos CONCYLIA. La unidad tecnica de medida fue la dosis diaria definida (DDD) y el indicador comparativo utilizado la DDD por 1.000 habitantes por dia (DHD). Resultados El consumo global fue elevado (21,21 DHD). A lo largo de los 5 anos estudiados se observaron variaciones importantes, especialmente en el ano 2003 en que se alcanzo el mayor consumo (25,05 DHD). Los subgrupos terapeuticos mas prescritos fueron las penicilinas de amplio espectro (8,08 DHD) y penicilinas asociadas a inhibidores de la betalactamasa (7,29 DHD), seguidas a mayor distancia por cefalosporinas (2,81 DHD) y macrolidos (2,52 DHD). El porcentaje de prescripcion de penicilinas de amplio espectro fue mas elevado que el de penicilinas asociada a inhibidores de la betalactamasa durante los anos 2001 y 2002, se igualo en el 2003 y se invirtio esta tendencia los ultimos 2 anos. Conclusiones Las diferencias de consumo fueron notables a lo largo del tiempo. Se observo un cambio en el patron de uso, principalmente a favor de las penicilinas asociadas a inhibidores de la betalactamasa los ultimos 2 anos.

: The human immunodeficiency virus (HIV) infection is a disease with great sociosanitary impact. Since 1981, when the first cases of AIDS were described, more than 60 million people have become infected. During these 25 years there have been a lot of advances in the infection management and we know that prevention and early diagnosis are crucial. Family Physician s role is essential since this is a privileged point of global attention, counseling and support for these patients. The main objective is to reduce the new HIV infections incidence. In addition, other objectives are: primary prevention and health promotion, early diagnosis, recruitment infected patients, monitoring and end-of-life caring. It is important to know that all of us are susceptible to contract the virus and, although the HIV testing is voluntary, there are screening recommendations from the CDC: persons with signs or symptoms that suggest infection, pregnant women, persons at high risk for infection and all patients aged 13-64 years, as a part of routine clinical care. The communication of the result is a key point in the therapeutic relation. If it is negative we must make intervention on risk attitudes. If it is positive we must inform and support the patient, to convince him about the need to be followed up by an specialized level. The AIDS terminal patient is a very immunodeficient one and needs palliative cares like other terminal disease. Another challenge is prevention and control of HIV infection among the immigrant community. In conclusion, Family Physicians must investigate risk practices, inform, prevent new cases and, in the infected people, monitor the evolution, supporting and comforting.

Background: Chicken pox is a mainly childhood contagious disease caused by the Varicella Zoster Virus which gives rise to major healthcare and social costs. In 2005, Castile and Leon added chicken pox vaccine injections to its childhood vaccination schedule for eleven year-olds subject to coming down with this disease. This strategy does not modify the major mobility generated thereby at younger ages. This study is aimed at evaluating the profitability of systematic vaccination for chicken pox in infants 15 months of age in Castile and Leon. Methods: An economic cost-benefit evaluation has been set out by jeans of a decision-making tree. A fictitious cohort of 100,000 children in Castile and Leon having reached 15 months of age in 2004 is studied, to whom the chicken pox vaccine would be administered in conjunction with the mumps, measles, rubella vaccines. This study is approached from the social standpoint. The time horizon selected was that of up until the study cohort was to reach 15 years of age, applying a 3% discount rate. A sensitivity analysis was made for evaluating the uncertainty of some variables... Results: The cost-benefit ratio of adding this vaccine to the childhood vaccination schedule amounts to 1.23. Conclusions: From the social standpoint, administering chicken pox vaccine in conjunction with the mumps, measles, rubella vaccines show itself to be profitable. The profitability is modified both if a second dose of vaccine is added as well as if only the direct healthcare costs are analyzed.

Las enfermedades infecciosas engloban las ocasionadas por bacterias, virus, hongos y parasitos, al tiempo que presentan un ambito absolutamente transversal en el que interesan a gran parte de las especialidades medicas y quirurgicas. En nuestro pais la realidad que configuran los diferentes sistemas de salud a nivel publico se apoya en la actividad de los laboratorios de Microbiologia, si bien se desdibujan en ocasiones algunas herramientas de utilidad en la vigilancia de las mismas. Parece necesario alinear a los medicos de Atencion Primaria para que actuen como agentes en la cultura del conocimiento, al tiempo que se deben establecer mecanismos practicos para integrarlos en sistemas de decision y control en este ambito de la patologia.

Objectives: Polyunsaturated fatty acids are immunomodulatory agents. These agents could develop a main role in patients with HIV infection. The aim of our study was to analyse the relation between polyunsaturated fatty acid intake and CD4 count in HIV infected patients. Patients and methods: Forty patients with HIV infections were enrolled. In all patients, the next variables were recorded; age, sex, drugs, anthropometric evaluation (weight, height, tricipital skinfold, midarm circumference, body mass index) and a biochemical evaluation (albumin, prealbumin, trasferrin, total proteins, total lymphocytes and CD4 count). A 3 day dietary intake questionnaire was performed, too. Results: The mean age was (24 males and 16 females) 37.6 ′ 9.4 years, mean weight 65.6 ′ 12.2 kg and body mass index 23.2 ′ 3.25. Anthropometric evaluation showed a mean tricipital skinfold of 15.1 ′ 5.3 mm, midarm circumference 27.5 ′ 3.1 cm. Caloric intake and macronutrient distribution were normal (carbohydrates 48%, proteins 18% and lipids 34%). Dietary intake of polyunsaturated fatty acids was omega 3 (1.22 ′ 3.1 g/day) and omega 9(31.5 ′ 11 g/day). Multivariante analysis, with CD4 count as a dependent variable, showed omega 3 intake as a independent variable (F = 6.2; p < 0.05), with an increase of 32 (IC95%; 9.86-52.14) CD4+ (count/uL) with each I g of omega 3 dietary intake adjusted by age, sex, and drugs. Conclusion: In patients with HIV infection, dietary intake of omega 3 fatty acids increase CD4 count.
