RESUMEN
BACKGROUND: Rotavirus (RV) vaccines are available in Spain since 2006 but are not included in the National Immunization Program. RV vaccination has reached an intermediate vaccination coverage rate (VCR) but with substantial differences between provinces. The aim of this study was to assess the ratio of RV gastroenteritis (RVGE) admissions to all-cause hospitalizations in children under 5 years of age in areas with different VCR. METHODS: Observational, multicenter, cross-sectional, medical record-based study. All children admitted to the study hospitals with a RVGE confirmed diagnosis during a 5-year period were selected. The annual ratio of RVGE to the total number of all-cause hospitalizations in children < 5 years of age were calculated. The proportion of RVGE hospitalizations were compared in areas with low (< 30%), intermediate (31-59%) and high (> 60%) VCR. RESULTS: From June 2013 to May 2018, data from 1731 RVGE hospitalizations (16.47% of which were nosocomial) were collected from the 12 study hospitals. RVGE hospital admissions accounted for 2.82% (95 CI 2.72-3.00) and 43.84% (95% CI 40.53-47.21) of all-cause and Acute Gastroenteritis (AGE) hospitalizations in children under 5 years of age, respectively. The likelihood of hospitalization due to RVGE was 56% (IC95%, 51-61%) and 27% (IC95%, 18-35%) lower in areas with high and intermediate VCR, respectively, compared to the low VCR areas. CONCLUSIONS: RVGE hospitalization ratios are highly dependent on the RV VCR. Increasing VCR in areas with intermediate and low coverage rates would significantly reduce the severe burden of RVGE that requires hospital management in Spain. Clinical trial registration Not applicable.

Enteroviruses (EV) have been linked to lymphocytic meningitis and exanthems, but they may also be involved in acute gastroenteritis (AGE), a condition whose aetiological agent often remains unidentified. In this work 1214 samples from individuals with AGE were studied with the aim of establishing the incidence of EV. The samples were collected between September and December in three different years and subjected to real-time genomic amplification in order to determine the viral load (VL). Of the 1214 samples studied, infection by a single virus was found in 328 cases (27%) and coinfection in 69 (5.7%). While adenoviruses (AdV) were the most frequent (14.8% of total), EV were present in 126 (10.4%) of the individuals tested. Of the 126 EV-positive samples, this virus was found as a single infection and coinfection in 76 (6.3%) and 50 (4.1%) cases, respectively. VL for EV was 5.58±1.51 log copies/ml (range 3.73-9.69) in the former and 6.27±1.75 (range 3.73-10.5) (p=0.02) in the latter. EV were identified in 97 children under 5 (16.9%) and in 29 (4.5%) patients over 5. Patients less than 5 years showed a higher VL that those more than 5 years age [6.08±1.57 (range 3.82-9.69) vs. 5.07±1.53 (range 3.73-10.58); (p=0.002)]. There was a high incidence of EV in AGE patients, and they were more frequent in those under 5, where they were found to replicate more efficiently. These results therefore indicate that testing for EV should be included in the diagnosis of AGE.

INTRODUCTION: S100ß protein has been proposed as a potential biomarker for both chronic and acute neurological disorders. Reference values of this protein are well defined in adults but not in children, in whom serum levels appear to vary with age. Reference values for serum S100ß in children from 0 to 14 years are presented. MATERIALS AND METHODS: A prospective study was conducted on 257 healthy children, who were divided into three age groups (under 12 months, 12 to 24 months and over 24 months). RESULTS: The study included179 boys and 78 girls, with a mean age of 5.5 (3.75) years. The mean serum concentration of protein S100ß was 0.156 (0.140-0.172) µg/l. In children under 12 months, serum S100ß concentration was 0.350 (0.280-0.421) µg/l; 0.165 (0.139-0.190) µg/l in the group between 12 and 24 months and 0.121 (0.109-0.133) µg/l in children older than 24 months. An inverse relationship was observed between age and serum S100ß, which declines as age increases. No differences were observed between sexes. CONCLUSIONS: The concentration of S100ß remains stable after two years of age, being possible to establish a baseline of S100ß for over two years. During the first two years of life, S100ß serum concentration is higher, the lower the age of the child. No differences in serum S100ß levels between sexes are observed.

Among the many fields of application of Ergonomics, this research deals with the services offered to Justice from the expertise recognized by the Law on prevention of occupational risks within the framework of the Law of Civil Procedure: Ergonomics forensic also called Legal Ergonomics. In Spain there are experiences since 1995 and an important development and this paper is to investigate the actions required for a more widespread use in trials. Consensus methods such as the Delphi survey technique are being employed to help enhance effective decision-making in the future development of Ergonomics Forensics. The Delphi survey is a group facilitation technique, which is an iterative multistage process, designed to transform opinion into group consensus. It is a flexible approach, that is used commonly within the health and social sciences, however, there is little use and practice of ergonomics as a technique to facilitate the participation of all experts involved: judges, lawyers and expert ergonomists.

Artificial neural networks (ANNs) have proven to be a tool for characterizing, modeling and predicting many of the non-linear hydrological processes such as rainfall-runoff, groundwater evaluation or simulation of water quality. After proper training they are able to generate satisfactory predictive results for many of these processes. In this paper they have been used to predict 1 or 2 days ahead the average and maximum daily flow of a river in a small forest headwaters in northwestern Spain. The inputs used were the flow and climate data (precipitation, temperature, relative humidity, solar radiation and wind speed) as recorded in the basin between 2003 and 2008. Climatic data have been utilized in a disaggregated form by considering each one as an input variable in ANN(1), or in an aggregated form by its use in the calculation of evapotranspiration and using this as input variable in ANN(2). Both ANN(1) and ANN(2), after being trained with the data for the period 2003-2007, have provided a good fit between estimated and observed data, with R(2) values exceeding 0.95. Subsequently, its operation has been verified making use of the data for the year 2008. The correlation coefficients obtained between the data estimated by ANNs and those observed were in all cases superior to 0.85, confirming the capacity of ANNs as a model for predicting average and maximum daily flow 1 or 2 days in advance.

INTRODUCTION AND OBJECTIVES: Advanced simulation (AS) is a teaching methodology that has shown to be useful for training health staff at hospital level; however, its application in primary care paediatrics is very limited. Our objective was the development of an AS project focused on the learning needs of the primary care paediatricians, as well as to know the participants' opinions as one of the elements to assess its appropriateness. MATERIAL AND METHODS: Phase 1: A multidisciplinary working group was organized and sponsored by the SEPEAP to design and put the course into practice. Phase 2: Itinerant courses were carried out in several cities in Spain. At the end of each course, a survey was carried out that was focused on motivation aspects, pertinence of contents and methodology. Each item was scored on a numerical scale from 0 (very bad) to 10 (very good). STUDY PERIOD: May 2008 to May 2009. RESULTS: After analysing the potential learning needs of target population, available time, teaching material available and methodology of simulation and debriefing, a course model was designed and the cases were programmed. Twelve courses were carried out in 12 cities. The total number of participants was 186; of them, 177 (95.2%) answered the survey. Mean+/-SD scores for main items were: organization (9.23+/-0.50), objectives related to prior expectation (9.29+/-0.43), usefulness of course program to work activity (9.42+/-0.43), cases that resemble reality (9.18+/-0.42) and good instructors-participants relationship (9.68+/-0.20). CONCLUSIONS: The AS course for primary care paediatrics, with the proposed format, is feasible and well adapted to the needs of the target population. Primary care paediatricians consider this type of teaching and learning activity as a useful tool for their continuing education and for improving their professional abilities.

INTRODUCTION: The advent of computed tomography (CT) has allowed the early detection of pathological changes in patients with cystic fibrosis (CF). Description of the early pathological changes and distribution of bronchiectasis in children with CF is limited, because most studies have been performed in older children and adults with well-established lung disease. The aim of this study was to describe the distribution pattern of this disease in Asturius. MATERIAL AND METHOD: We performed a retrospective study of the medical records and CT scans of patients followed up in our Cystic Fibrosis Unit. CT scans were scored by two radiologists according to Bhalla and Nathanson scores. Pathological changes were analyzed and correlated with clinical data and pulmonary function tests. RESULTS: The 41 CT reviewed contained between 10 and 47 slices, with a median of 16. The total number of slices was 758, of which 606 (79.95%) were considered acceptable and 152 were considered unacceptable by the radiologists. The most frequent lesions found were bronchiectasis (78.38%), followed by mucous plugs (37.84%). The most frequently affected bronchopulmonary segments were S1 and S2 in the right lung. Statistically significant correlations were found between Bhalla and Nathanson scores and disease duration. No statistically significant correlations were found between Bhalla and Nathanson scores and pulmonary function tests. CONCLUSIONS: The most frequent lesions in our environment were bronchiectasis followed by mucous plugs. The upper right lobe was the first to be affected, which correlates with findings in most published studies.

OBJECTIVE: To analyze chronic obstructive lung disease (COPD) subjects in acute hypercapnic failure who were treated with non-invasive mechanical ventilation in a general respiratory ward. METHODS: This was a two-year prospective study of 35 patients with acute exacerbation of COPD and mean FEV1/FVC relation in stable condition of 55.3 +/- 14.8% of predicted that were treated with positive pressure respiration using a facemask in a general respiratory ward. 17 (48.5%) receive long-term oxygen therapy. Analysis was made of blood gases, before and after treatment of non-invasive ventilation, complications, and failure during treatment. RESULTS: A significant improvement in blood gases was observed 24 hours after non-invasive ventilation treatment. The mean hospital stay was of 15.0 +/- 9.1 days and failures were registered in 3 cases (8.5%). Facial scares were the most common complication (13 patients) but it was possible to continue treatment. CONCLUSIONS: Non-invasive ventilation is a viable treatment for patients with chronic obstructive lung disease and acute hypercapnic failure being treated in a general respiratory ward.

OBJECTIVE: The purpose of this study was to determine the epidemiological characteristics of tuberculosis (TB) in the Public Health System District of Santiago de Compostela (population : 386125) from 1999 to 2002. METHODS: Inclusion criteria were: 1). microbiological and/or pathological diagnosis of TB in any specimen, and 2). patient younger 35 years old with recent medical history of TB. Mantoux test positive, and pleural effusion with linfocitosis and adenosine deaminase >47 IU/ml. RESULTS: 946 patients were included (568 men and 378 women), with ages ranging from 2 months to 96 years. The incidence of TB was 60.9/100000 in 1999, 67.6/100000 in 2000, 61.9/100000 in 2001 and 54.6/100000 in 2002. The incidence rate of tuberculous meningitis was 1.03/100000 in 1999 and 2000, 0.77/100000 in 2001 and 0.51/100000 in 2002. The percentage of cases associated with HIV was 3.4% in 1999, 1.9% in 2000, 2.4% in 2001 and 2002. We found an increase in the rate of males over 55 years of age; with incidence per 100000 inhabitants of 122.4 in 1999, 142.8 in 2000, 115 in 2001 and 119 in 2002, whereas in females the incidence was 40.6 in 1999, 60.9 in 2000, 54.1 in 2001 and 39.1 in 2002. CONCLUSIONS: In last four years the incidence of tuberculosis has decreased but remains high in males over 55 years old.

OBJECTIVE: Ventricular septal defect is the most frequently diagnosed congenital heart defect. The prognosis is usually good. The aim of this study was to describe this idea to general pediatricians. MATERIAL AND METHODS: We review the follow-up of 81 patients with ventricular septal defect. Defects that spontaneously closed in the first 12 months of life and those that formed part of a malformative syndrome or a complex congenital heart defect were excluded. RESULTS: Localization was perimembranous, including all defects affecting mainly the septal membrane independent of whether the surrounding tissues were involved, in 66.7 %, muscular in 29.6 % and mixed in 3.7 %. Perimembranous position was more frequent among large and medium-sized defects. Large and perimembranous defects were characterized by holosystolic murmur; in small, muscular defects, murmur was cut off in mid-systole. In 45.8 % of large defects, weight development was delayed, but there was no appreciable effect on height. Generally we observed a tendency to partial closure and to improvement. Surgical closure was required in 9.8 %. CONCLUSIONS: Because of the trend to partial or complete spontaneous closure, the prognosis of ventricular septal defect is generally good.

INTRODUCTION: Respiratory diseases are a frequent cause of health demands and have a large impact on morbidity and mortality of the Galician population, especially among the older one. Recent work shows that the diagnosis and treatment of these diseases is not optimal. This increases the utilisation of health care resources. MATERIAL AND METHODS: We studied 28 patients of the municipality of Val del Dubra (Northwest Spain) aged between 65 and 74 years. We performed a spirometric exploration and carried out a questionnaire interview on respiratory symptoms, life style, and occupational and health-related antecedents. RESULTS: Among men, 54% of were or are smokers. None of the women ever smoked. Respiratory symptoms were more frequent among women than among men (80% versus 54%). In the spirometric study, the largest volumes and flux are observed among non-smoking males who do not report dyspnea. DISCUSSION: Respiratory symptoms are frequent in the rural population aged between 65 and 74 years. Tobacco consumption is similar to other Spanish communities, but different from that seen in other countries. Male gender, non-smoking status and absence of respiratory symptoms are associated with higher spirometric figures.

OBJECTIVE: The aim of our work has been the study of CO diffusion capacity in mitral valve stenosis patients. METHOD: We have studied 15 control subjects and 15 patients with mitral valve stenosis. We performed spirometry study and CO pulmonary diffusion tests (DLCO) by single breath method to determine two components: pulmonary capillary blood volume (Vc) and membrane diffusion factor (Dm). In addition, in mitral valve stenosis patients we performed a ecocardiography-doppler study. RESULTS: The mitral valve stenosis group had higher values of DLCO and Vc and a lower ratio of Dm/Vc than the control group. There is a negative correlation between Vc and the mitral valve area (r = -0.63; p = 0.037). We do not find any another correlation between the rest of ecocardiography doppler parameters and lung function test variables that we have measured. We have not found any differences between both groups in Dm. CONCLUSIONS: Mitral valve stenosis patients present a increase of CO pulmonary diffusion capacity and pulmonary capillary blood volume without changes in membrane diffusion factor.

OBJECTIVE: The aim of our work has been the study and comparison of diffusion capacity of CO (DLCO) in two different clinical situations: bronchial asthma and diabetes mellitus. METHOD: We have studied 16 control subjects, 38 patients with bronchial asthma and 65 patients with diabetes mellitus. We performed CO pulmonary diffusion tests by single breath method to determine two components: membrane diffusion factor (Dm) and pulmonary capillary blood volume (Vc). RESULTS: We have found a positive correlation of FEV1 with Dm. The bronchial asthma group had a lower FEV1 and FEF25-75% and an increase in DLCO, Dm and Vc, with respect to the control group. The diabetes mellitus group presented a decrease in CVF, FEV1, DLCO and Vc, with respect to the control group. The bronchial asthma group showed a lower ratio of Dm/Vc than the control and diabetes groups. CONCLUSIONS: The bronchial asthma patients have an increase in CO pulmonary diffusion, membrane diffusion factor and pulmonary capillary volume. However, the diabetes mellitus patients present a decrease in CO pulmonary diffusion mainly due to pulmonary capillary volume.

The sleep apnea syndrome is a common disease, recognised as a public health problem. Cardiovascular disease is the most frequent cause of morbidity and mortality in these patients, however the underlying mechanisms of this association have not been clearly established. In sleep apnea syndrome different phenomena can be produced which may explain the appearance of cardiovascular problems, such a progressive hypoxia in relationship with the apnea, the increases of intrathoracic pressure cause by the efforts of ventilation system against close upper airway and the modifications of the autonomic nervous system associated with the arousals. In addition, the hypoxia episodes and reoxygenation, which appear in the sleep apnea syndrome, may play a important role in the alteration of the balance between vasoconstriction and vasodilatation substances affecting the vascular homeostasis and conditioning endothelial dysfunction. On the other hand, the increasing of platelets aggregation and the decreased of fibrinolisis in this group of patients may cause vascular diseases.

BACKGROUND: We report the epidemiological characteristics of tuberculosis(TB) in the area of Santiago de Compostela (Spain) between 1995 and 1998. METHODS: Inclusion criteria were: 1) microbiological and/or pathological diagnosis of TB in any specimen, and 2) consistent recent medical history of TB with reading > 5 mm to 2 TU PPD tuberculin test 48-72 hours after injection, and adenosine deaminase in pleural effusion > 47 IU/ml. RESULTS: 1,150 patients were included (685 males and 465 females), with mean of age (X) 38.9 years (19.8 SD), range 3 months-88 years. The number of cases was 307 during 1995 and 1996, 302 in 1997 and 213 in 1998. The incidence rate (per 100,000 habitants) was 78.3 in 1995 and 1996, 79.8 in 1997 and 61.9 in 1998. The incidence rate of meningitis was 1.8 in 1995, 1.3 in 1996, 1.05 in 1997 and 0.8 in 1998, with no meningitis in children under 5 years. Cases in association with VIH were 4.2% in 1995, 3.3 in 1996, 5.4 in 1997 and 3.2 in 1998. More of the 50% of cases in both genders were between 15 and 40 years old with another peak over 65 years. The ratio men/woman was 1.8 in 1995 and 1.4 in 1996, 1997 and 1998. CONCLUSIONS: The incidence of tuberculosis has diminished during the last year, but is too early to know the real tendency.

OBJECTIVES: To evaluate patient compliance with inhaled medication therapy in chronic obstructive pulmonary disease (COPD), to identify determining factors and to propose corrective measures to improve compliance. METHODS: This was an open, observational, cross-sectional, non-comparative, single-measurement, non-random study. The inhalers were the Serevent Accuhaler, the Serevent Inhalador and the Flixotide Inhaler. Compliance was measured in four ways: a) difference in weight at the beginning and end of the study for all devices; b) dose counter reading for the Accuhaler; c) information from patient diaries (by days and by applications); and d) information from patient interviews using the Morinsky-Green Test. Compliance was rated as follows: poor: < 50%, fair 51%-79%, good 80%-119%, or "hypercompliant" > 120%. RESULTS: Seventy-two patients (mean age 65 years) were enrolled. Compliance measured by weight was good in 77.1%, fair in 11.5%, poor in 1.4% and hypercompliant in 10%. Compliance was good for the Accuhaler according to both weight (75%) and counted doses (83.3%). According to patient diaries, compliance was good when assessed by applications (98.8%) and by days (98.3%). According to the Morinksky-Green test, compliance was good for 87.9%. CONCLUSIONS: Compliance was good as assessed by the methods used in this study. Patients who live in families, who enjoy a high socioeconomic level, have simple therapeutic regimens and have a good understanding of their disease and inhaler tend to have good compliance. Careful patient follow-up and good patient-physician communication has improved compliance. However, follow-up studies are needed to check these results.
