[Evolution of smoking prevalence in Spain and its 17 autonomous regions (1987-2020)]. / Evolución de la prevalencia de consumo de tabaco en España y sus 17 comunidades autónomas (1987-2020).

BACKGROUND AND OBJECTIVES: Continuous monitoring of smoking prevalence is essential to understand the evolution of the tobacco epidemic in a population. The objective of this study was to analyze the evolution of smoking prevalence in Spain and its 17 Autonomous Regions (ARs) in population ≥15 years during the period 1987-2020. METHODS: Tobacco consumption data were derived from the National Health Survey of Spain and the European Health Survey in Spain. A smoker was defined as a person who smoked at the time of the survey. The trend in prevalences by sex in Spain and its ARs was analyzed by applying joinpoint models. Age-standardized prevalences were calculated for Spain by applying the direct method. RESULTS: In Spain, the prevalence of consumption decreased 29 percentage points in men and 4.5 in women between 1987-2020. In men, the smoking prevalence decreased in all the ARs and the absolute change varied between -19.5% in the Balearic Islands and -33.9% in Andalusia. In women, the evolution of smoking prevalence differed between ARs. The absolute change varied between -15.4% in Basque Country and 0.5% in Andalusia. CONCLUSIONS: The number of men and women smokers has decreased in Spain between 1987-2020. Different patterns of evolution of the prevalence of consumption are observed among the ARs, especially among women. This reinforces the need for policies adapted to more local contexts and that take into account the gender perspective.

Tobacco Patterns and Risk of Chronic Obstructive Pulmonary Disease: Results From a Cross-Sectional Study

Introduction: There is still uncertainty about which aspects of cigarette smoking influence the risk of Chronic Obstructive Pulmonary Disease (COPD). The aim of this study was to estimate the COPD risk as related to duration of use, intensity of use, lifetime tobacco consumption, age of smoking initiation and years of abstinence. Methods: We conducted an analytical cross-sectional study based on data from the EPISCAN-II study (n=9092). All participants underwent a face-to-face interview and post-bronchodilator spirometry was performed. COPD was defined as post-bronchodilator FEV1/FVC<70%. Parametric and nonparametric logistic regression models with generalized additive models were used. Results: 8819 persons were included; 858 with COPD and 7961 without COPD. The COPD risk increased with smoking duration up to ≥50 years [OR 3.5 (95% CI: 2.3–5.4)], with smoking intensity up to ≥39cig/day [OR 10.1 (95% CI: 5.3–18.4)] and with lifetime tobacco consumption up to >29 pack-years [OR 3.8 (95% CI: 3.1–4.8)]. The COPD risk for those who started smoking at 22 or later was 0.9 (95% CI: 0.6–1.4). The risk of COPD decreased with increasing years of cessation. In comparison with both never smokers and current smokers, the lowest risk of COPD was found after 15–25 years of abstinence. Conclusion: COPD risk increases with duration, intensity, and lifetime tobacco consumption and decreases importantly with years of abstinence. Age at smoking initiation shows no effect. After 15–25 years of cessation, COPD risk could be equal to that of a never smoker. This work suggests that the time it takes to develop COPD in a smoker is about 30 years. (AU)

INTRODUCTION: Clinical features and outcomes of SARSCoV-2 infections may change between different waves of the pandemic. The objective of this study was to compare clinical characteristics and outcomes between two cohorts of patients hospitalized for COVID-19 during the first and second waves in Argentina. METHODS: Multicenter and prospective registry of patients =18 years old with a confirmed diagnosis of COVID-19 admitted to 18 hospitals in Argentina during the first wave (March to October 2020) and second wave (March to July 2021) of the pandemic. Demographics, clinical characteristics, and outcomes of these patients were compared. RESULTS: A total of 1691 patients were included (first wave n = 809, second wave n = 882). Hospitalized patients during the second wave were older (median 53 years vs. 61 years, p < 0.001), had more comorbidities (71% vs. 77%, p=0.007) and required more supplemental oxygen at admission (21% vs 62%, p < 0.001). During hospitalization, patients of the second wave required more supplemental oxygen (49% vs. 85%, p < 0.001), invasive ventilation (12% vs. 22%, p < 0.001) and had higher 30- day mortality (11% vs. 26%, p < 0.001). Comparing only patients who required supplemental oxygen during hospitalization, 30-day mortality was 20% and 30% p < 0.001 for the first and second wave, respectively. CONCLUSION: Compared to patients admitted during the first wave, patients admitted with SARS-CoV2 during the second wave in Argentina were more seriously ill and had a higher mortality.

Pregnancy outcomes in 1869 pregnancies in a large cohort from the Spanish Society of Rheumatology Lupus Register (RELESSER).

INTRODUCTION: Obstetric complications are more common in women with systemic lupus erythematosus (SLE) than in the general population. OBJECTIVE: To assess pregnancy outcomes in women with SLE from the RELESSER cohort after 12 years of follow-up. METHODS: A multicentre retrospective observational study was conducted. In addition to data from the RELESSER register, data were collected on obstetric/gynaecological variables and treatments received. The number of term pregnancies was compared between women with pregnancies before and after the diagnosis of SLE. Further, clinical and laboratory characteristics were compared between women with pregnancies before and after the diagnosis, on the one hand, and with and without complications during pregnancy, on the other. Bivariate and multivariate analyses were carried out to identify factors potentially associated with complications during pregnancy. RESULTS: A total of 809 women were included, with 1869 pregnancies, of which 1395 reached term. Women with pregnancies before the diagnosis of SLE had more pregnancies (2.37 vs 1.87) and a higher rate of term pregnancies (76.8% vs 69.8%, p < 0.001) compared to those with pregnancies after the diagnosis. Women with pregnancies before the diagnosis were diagnosed at an older age (43.4 vs 34.1 years) and had more comorbidities. No differences were observed between the groups with pregnancies before and after diagnosis in antibody profile, including anti-dsDNA, anti-Sm, anti-Ro, anti-La, lupus anticoagulant, anticardiolipin or anti-beta-2-glycoprotein. Overall, 114 out of the 809 women included in the study experienced complications during pregnancy, including miscarriage, preeclampsia/eclampsia, foetal death, and/or preterm birth. Women with complications had higher rates of antiphospholipid syndrome (40.5% vs 9.9%, p < 0.001) and higher rates of positivity for IgG anticardiolipin (33.9% vs 21.3%, p = 0.005), IgG anti-beta 2 glycoprotein (26.1% vs 14%, p = 0.007), and IgM anti-beta 2 glycoprotein (26.1% vs 16%, p = 0.032) antibodies, although no differences were found regarding lupus anticoagulant. Among the treatments received, only heparin was more commonly used by women with pregnancy complications. We did not find differences in corticosteroid or hydroxychloroquine use. CONCLUSIONS: The likelihood of term pregnancy is higher before the diagnosis of SLE. In our cohort, positivity for anticardiolipin IgG and anti-beta-2- glycoprotein IgG/IgM, but not lupus anticoagulant, was associated with a higher risk of poorer pregnancy outcomes.

Mass Switch From Intravenous to Subcutaneous Tocilizumab in Rheumatic Diseases During the SARS-COV-2 Pandemic.

BACKGROUND: With the arrival of the SARS-CoV-2 pandemic in 2020, it was proposed to make the change from intravenous (IV) tocilizumab (TCZ) to its subcutaneous formulation, in order to avoid rheumatological patients having to go to the day hospital and guarantee enough IV TCZ for those critical patients with COVID who needed it. The aim of this study was to describe the rate and reasons for switching back to IV TCZ from subcutaneous TCZ. METHODS: We included patients from the rheumatology service that were on treatment with IV TCZ in February 2020 and were followed up until March 2021. Patients that remained on subcutaneous TCZ were compared with those who switched back to IV TCZ (switch-back group). A subgroup analysis according to rheumatic disease was performed. RESULTS: Fifty-five patients switched to subcutaneous TCZ: 28 rheumatoid arthritis, 19 giant cell arteritis, 4 polymyalgia rheumatica, 2 juvenile idiopathic arthritis, and 2 systemic sclerosis. Seventeen patients switched back to IV TCZ due to ineffectiveness (n = 8), patient preference (n = 4), adverse events (n = 4), and difficulty with the SC administration route (n = 1). In the analysis by disease, 4 of 23 patients switched back to IV TCZ in giant cell arteritis/polymyalgia rheumatica group due to ineffectiveness (n = 2), injection site reaction (n = 1), or patient preference (n = 1). In rheumatoid arthritis group, 11 of 28 patients switched back to IV TCZ: ineffectiveness (n = 5), patient preference (n = 3), headache (n = 1), injection site reaction (n = 1), and due to difficulty with the SC administration route (n = 1). CONCLUSIONS: Mass switch from IV to subcutaneous TCZ during the SARS-CoV-2 pandemic has been safe, effective, and well tolerated after 1 year of follow-up.

Clinical and Serological Features in Latin American IgG4-Related Disease Patients Differ According to Sex, Ethnicity, and Clinical Phenotype.

BACKGROUND/OBJECTIVE: Data on IgG4-related disease (IgG4-RD) come almost exclusively from cohorts from Asia, Europe, and North America. We conducted this study to describe the clinical presentation, phenotype distribution, and association with sex, ethnicity, and serological markers in a large cohort of Latin American patients with IgG4-RD. METHODS: We performed a multicenter medical records review study including 184 Latin American IgG4-RD patients. We assigned patients to clinical phenotypes: group 1 (pancreato-hepato-biliary), group 2 (retroperitoneal/aortic), group 3 (head and neck-limited), group 4 (Mikulicz/systemic), and group 5 (undefined). We focused the analysis on how sex, ethnicity, and clinical phenotype may influence the clinical and serological presentation. RESULTS: The mean age was 50.8 ± 15 years. Men and women were equally affected (52.2% vs 48.8%). Fifty-four patients (29.3%) were assigned to group 1, 21 (11.4%) to group 2, 57 (30.9%) to group 3, 32 (17.4%) to group 4, and 20 (10.8%) to group 5. Male sex was associated with biliary tract (odds ratio [OR], 3.4; 95% confidence interval [CI], 1.36-8.26), kidney (OR, 3.4; 95% CI, 1.28-9.25), and retroperitoneal involvement (OR, 5.3; 95% CI, 1.45-20). Amerindian patients presented more frequently with atopy history and gallbladder involvement. Group 3 had a female predominance. CONCLUSIONS: Latin American patients with IgG4-RD were younger, and men and women were equally affected compared with White and Asian cohorts. They belonged more commonly to group 1 and group 3. Retroperitoneal and aortic involvement was infrequent. Clinical and serological features differed according to sex, ethnicity, and clinical phenotype.

Prescription of anxiolytics, sedatives, hypnotics and antidepressants in outpatient, universal care during the COVID-19 pandemic in Portugal: a nationwide, interrupted time-series approach.

BACKGROUND: The COVID-19 pandemic has had a significant impact on the population's mental health. However, its impact on the consumption of anxiolytics, sedatives, hypnotics and antidepressants remains to be evaluated. Hence, this article aims to assess the prescription trends of these drugs in Portugal, from January 2018 to March 2021, while critically examining whether the COVID-19 pandemic had an impact on these prescription trends or not. METHODS: A nationwide interrupted time-series analysis of the prescription data of anxiolytics, sedatives, hypnotics and antidepressants in outpatient setting of the public health sector was conducted. The data encompassed the defined daily dose per month, age range and sex and were analysed following a segmented regression approach. RESULTS: The pandemic preceded an immediate reduction in the prescription of anxiolytics, sedatives and hypnotics for children and adolescents. However, an increasing trend throughout the pandemic has been noted in the prescription of these drugs, especially among adults aged 65 years or above. A drop in antidepressant prescription was observed as an immediate effect of the pandemic among male and female adolescents and elderly women. From March 2020 to March 2021, a decreasing prescription trend has been noted among men. CONCLUSIONS: When analysing specific genders and age ranges, differences can be noted, in terms of both immediate impact and prescribing trends throughout 1 year of the COVID-19 pandemic. The impact of the pandemic on mental health and its association with the consumption trends of psychoactive drugs, and with the access to mental health treatments, should be further assessed.

Fruits and Vegetables and Lung Cancer Risk in Never Smokers. A Multicentric and Pooled Case-Control Study.

BACKGROUND: The etiology of lung cancer in never smokers is partly unknown. We aimed to assess the effect of fruits and vegetables consumption on lung cancer risk in never smokers. METHODS: We pooled five multicenter case-control studies performed in Northwestern Spain. Cases and controls were all never smokers. All lung cancer cases had anatomopathological confirmed diagnoses. We performed a multivariate logistic regression to analyze the effect of different types of fruits and vegetables consumption on lung cancer risk. RESULTS: A total of 438 cases and 781 controls were included. We observed that a consumption from one to six times per week shows a negative association with lung cancer risk for: kiwis (OR 0.67; 95%CI 0.46-0.95), oranges (OR 0.55; 95%CI 0.37-0.80), turnip tops (OR 0.48; 95%CI 0.34-0.66), "berza gallega" (OR 0.70; 95%CI 0.51-0.97) and broccoli (OR 0.55; 95%CI 0.35-0.83) compared to less than once a week consumption. On the other hand, we found an increased risk for lung cancer with a daily consumption of tomatoes, carrots and potatoes. CONCLUSIONS: Oranges, kiwis, turnip tops, berza gallega and broccoli may play a protective role on lung cancer development in never smokers while tomatoes, carrots and potatoes might have some association with this disease.

Clinical characteristics and outcomes of hospitalized patients with SARS-CoV-2 infection in a Latin American country: Results from the ECCOVID multicenter prospective study.

BACKGROUND: Clinical features and outcomes of SARS-CoV-2 infections diverge in different countries. The aim of this study was to describe clinical characteristics and outcomes in a cohort of patients hospitalized with SARS-CoV-2 in Argentina. METHODS: Multicenter prospective cohort study of ≥18 years-old patients with confirmed SARS-CoV-2 infection consecutively admitted to 19 hospitals in Argentina. Multivariable logistic regression models were used to identify variables associated with 30-day mortality and admission to intensive care unit (ICU). RESULTS: A total of 809 patients were analyzed. Median age was 53 years, 56% were males and 71% had at least one comorbidity. The most common comorbidities were hypertension (32%), obesity (23%) and diabetes (17%). Disease severity at admission was classified as mild 25%, moderate 51%, severe 17%, and critical 7%. Almost half of patients (49%) required supplemental oxygen, 18% ICU, and 12% invasive ventilation. Overall, 30-day mortality was 11%. Factors independently associated with ICU admission were male gender (OR 1.81; 95%CI 1.16-2.81), hypertension (OR 3.21; 95%CI 2.08-4.95), obesity (OR 2.38; 95%CI 1.51-3.7), oxygen saturation ≤93% (OR 6.45; 95%CI 4.20-9.92) and lymphopenia (OR 3.21; 95%CI 2.08-4.95). Factors independently associated with 30-day mortality included age ≥60 years-old (OR 2.68; 95% CI 1.63-4.43), oxygen saturation ≤93% (OR 3.19; 95%CI 1.97-5.16) and lymphopenia (OR 2.65; 95%CI 1.64-4.27). CONCLUSIONS: This cohort validates crucial clinical data on patients hospitalized with SARS-CoV-2 in Argentina.

Growth Patterns in Children With Congenital Cytomegalovirus Infection.

BACKGROUND: Congenital cytomegalovirus infection (CMVc) affects 0.7%-6% of recent births. Among its clinical manifestations are low weight and length at birth. OBJECTIVE: Describe the growth patterns of children with CMVc in their early years. METHODS: Observational, multicenter study of patients with CMVc. Anthropometric data were collected during the first 2 years of life and compared with World Health Organization standards. RESULTS: Anthropometric characteristics of 383 children with CMVc were studied, of which 198 (51%) were symptomatic at birth. At birth, 9% were small for gestational age (SGA) in terms of their weight and length and 17% had microcephaly. At 24 ± 3 months, 10% had a weight and length ≤2 SD, and 13% a head circumference ≤2 SD. Of those who were SGA at birth, at 24 ± 3 months >20% remained at ≤2 SD of their weight and length. Conversely, 75% of children with low weight or length at 24 ± 3 had not been SGA at birth. 20% of infants with microcephaly at birth remained with microcephaly, and 10% of those without microcephaly developed it at 24 ± 3 months. The average growth rate in length and weight was normal. Patients who were symptomatic at birth, premature and with motor and neurocognitive impairment had a significantly higher risk of low weight and length at 24 ± 3 months. CONCLUSION: Around 10% of children with CMVc are at ≤2 SD in weight, length and head circumference at 24 ± 3 months. The lack of adequate growth is associated with symptoms at birth, prematurity and motor and neurocognitive impairment. Growth impairment could be incorporated into the symptomatic spectrum of CMVc.

Survival times for cats with hyperthyroidism treated with a 3.35 mCi iodine-131 dose: a retrospective study of 96 cases.

Objectives Radioiodine (131I) dose determination using radiotracer kinetic studies or scoring systems, and fixed relatively high 131I dose (ie, 4 or 5 mCi) administration, are effective and associated with prolonged survival times for hyperthyroid cats. The latter method is less complicated but could expose patients and veterinary personnel to unnecessary levels of radiation. The aim of this study was to retrospectively evaluate the efficacy of a fixed 3.35 mCi 131I dose for the treatment of 96 hyperthyroid cats with no length estimation for any palpated goitre ⩾20 mm, assess outcome and identify factors associated with survival. Methods Serum total thyroxine concentrations at diagnosis and at follow-up times, survival times and cause of death were recorded. Multivariable Cox regression analysis was used to identify factors associated with time to any cause of death from 131I therapy initiation. Results Administration of a median (interquartile range) dose of 3.35 mCi (3.27-3.44 mCi) radioiodine was an effective treatment in 94/96 cats, but two cats remained hyperthyroid. No death related to hyperthyroidism was recorded. Median survival time was 3.0 years; the 1 and 2 year survival rates after 131I therapy were 90% and 78%, respectively. Low body weight (⩽3.1 kg; adjusted hazard ratio [aHR] 5.88; 95% confidence interval [CI] 2.22-16.67; P <0.01) and male gender (aHR 2.63; 95% CI 1.01-7.14; P = 0.04) were independently associated with death, whereas age, prior treatment with antithyroid drugs, reason for treatment and pretreatment azotaemia were not. Conclusions and relevance This study suggests that a fixed 3.35 mCi 131I dose treatment is effective for hyperthyroid cats with goitre(s) with a maximal length estimation <20 mm, that long-term survival can be achieved and that low body weight and male gender are significantly associated with shorter survival times.

Alcohol consumption and lung cancer risk in never smokers: a pooled analysis of case-control studies.

Background: Lung cancer is the deadliest cancer in developed countries but the etiology of lung cancer risk in never smokers (LCRINS) is largely unknown. We aim to assess the effects of alcohol consumption, in its different forms, on LCRINS. Methods: We pooled six multi-center case-control studies developed in the northwest of Spain. Cases and controls groups were composed of never smokers. We selected incident cases with anatomopathologically confirmed lung cancer diagnoses. All participants were personally interviewed. We performed two groups of statistical models, applying unconditional logistic regression with generalized additive models. One considered the effect of alcohol type consumption and the other considered the quantity of each alcoholic beverage consumed. Results: A total of 438 cases and 863 controls were included. Median age was 71 and 66, years, respectively. Adenocarcinoma was the predominant histological type, comprising 66% of all cases. We found that any type of wine consumption posed an OR of 2.20 OR 95%CI 1.12-4.35), and spirits consumption had an OR of 1.90 (95%CI 1.13-3.23). Beer consumption had an OR of 1.33 (95%CI 0.82-2.14). These results were similar when women were analyzed separately, but for men there was no apparent risk for any alcoholic beverage. The dose-response analysis for each alcoholic beverage revealed no clear pattern. Conclusions: Wine and spirits consumption might increase the risk of LCRINSs, particularly in females. These results have to be taken with caution given the limitations of the present study.

Residential radon in Galicia: a cross-sectional study in a radon-prone area.

Residential radon exposure is a major public health problem. It is the second greatest cause of lung cancer, after smoking, and the greatest in never-smokers. This study shows the indoor radon exposure distribution in Galicia and estimates the percentage of dwellings exceeding reference levels. It is based on 3245 residential radon measurements obtained from the Galician Radon Map project and from controls of two previous case-control studies on residential radon and lung cancer. Results show a high median residential radon concentration in Galicia (99 Bq m-3), with 49.3% of dwellings having a radon concentration above 100 Bq m-3 and 11.1% having a concentration above 300 Bq m-3. Ourense and Pontevedra, located in South Galicia, are the provinces with the highest median indoor radon concentrations (137 Bq m-3 and 123.5 Bq m-3, respectively). Results also show lower radon levels in progressively higher building storeys. These high residential radon concentrations confirm Galicia as a radon-prone area. A policy on radon should be developed and implemented in Galicia to minimize the residential radon exposure of the population.

Identifying Predictors and Prevalence of Alcohol Consumption among University Students: Nine Years of Follow-Up.

AIM: To evaluate the prevalence of alcohol consumption among university students during late adolescence and young adulthood and to identify the associated factors. MATERIAL AND METHODS: Cohort study among university students in Spain (n = 1382). Heavy Episodic Drinking (HED) and Risky Consumption (RC) were measured with the Alcohol Use Disorders Identification Test (AUDIT) at ages 18, 20, 22, 24 and 27 years. Data on potential factors associated with alcohol use were obtained with an additional questionnaire. Multilevel logistic regression for repeated measures was used to obtain adjusted OR (Odds Ratios). RESULTS: The rates of prevalence of RC were lower, but not statistically significant, in women. The age-related changes in these rates were similar in both genders, and the prevalence of RC peaked at 20 years. By contrast, the prevalence of HED was significantly lower in women and peaked at 18 years in women and at 22 years in men. Multivariate models showed that early age of onset of alcohol use (OR = 10.6 and OR = 6.9 for women; OR = 8.3 and OR = 8.2 for men) and positive expectations about alcohol (OR = 7.8 and OR = 4.5 for women; OR = 3.6 and OR = 3.3 for men) were the most important risk factors for RC and HED. Living away from the family home was also a risk factor for both consumption patterns among women (OR = 3.16 and OR = 2.34), while a high maternal education level was a risk factor for RC among both genders (OR = 1.62 for women; OR = 2.49 for men). CONCLUSIONS: Alcohol consumption decreases significantly at the end of youth, with higher rates of prevalence and a later peak among men. Prevention strategies should focus on beliefs and expectations about alcohol and on delaying the age of onset. Women are at particular risk for these consumption patterns if they live away from their parents. Belonging to a high-income family is a strong risk factor for RC.

Automated external defibrillation skills by naive schoolchildren.

AIM: Early defibrillation should achieve the highest survival rates when applied within the first minutes after the collapse. Public access defibrillation programs have increased the population awareness of the importance of defibrillation. Schoolchildren should be trained in basic life support (BLS) skills and some countries have included BLS in their school syllabus. However, little is known of the current knowledge and ability of schoolchildren to use an automated external defibrillator (AED). METHODS: A multicentric descriptive study, 1295 children from 6 to 16 years of age without previous BLS or AED training. Subjects performed a simulation with an AED and a manikin with no training or feedback and were evaluated by means of a checklist. RESULTS: A total of 258 participants (19.9%) were able to simulate an effective and safe defibrillation in less than 3min and 52 (20.1% of this group) performed it successfully. A significant correlation between objective and age group was observed (G=0.172) (p<0.001). The average time to deliver a shock was 83.3±26.4s; that time decreased significantly with age [6 YO (108.3±40.4) vs. 16 YO (64.7±18.6)s] (p<0.001). CONCLUSIONS: Around 20% of schoolchildren without prior training are able to use an AED correctly in less than 3min following the device's acoustic and visual instructions. However, only one-fifth of those who showed success managed to complete the procedure satisfactorily. These facts should be considered in order to provide a more accurate definition and effective implementation of BLS/AED teaching and training at schools.

¿Limitación o incapacidad laboral? / Occupational limitation or disability?

La dificultad a la hora de plantearnos si un trabajador con limitaciones físico-psíquicas para su puesto de trabajo sería candidato a una incapacidad permanente, nos ha llevado a la elaboración de un protocolo. Son fundamentales la valoración médica del trabajador y la técnica de su puesto de trabajo, y confrontar las limitaciones que presenta con las tareas que debe efectuar. Se debe explicar adecuadamente al trabajador la imposibilidad de realizar las tareas principales de su puesto de trabajo por las limitaciones que presenta debidas a su patología, no siendo posible su adaptación. Por último no se debe olvidar la posibilidad de consultar con la Unidad Médica de la Dirección Provincial del Instituto Nacional de la Seguridad Social (INSS) para la orientación y asesoría (AU)

The difficult situation to differentiate if a worker, with physical-physic limitation, would be a candidate for a permanent incapacity performing his/her job, lead us to elaborate a protocol. The medical evaluation and the knowing of the tasks of the job are essential, and confront the limitations that represent the tasks that the worker must perform. The impossibility to perform the main tasks of her/his job due to the pathology must be properly explained to the worker. Finally we can not forget the possibility to enquiry witch the Medical Unit of the Provincial Direction of the Nacional Social Security (INSS) for the correct orientation and advice (AU)

Patologías relacionadas con las condiciones ambientales de un hospital terciario de la Comunidad de Madrid / Diseases caused by environmental conditions in a tertiary hospital of Madrid

INTRODUCCIÓN: El Síndrome del edificio enfermo (SEE) cursa con una mayor incidencia de síntomas como cefaleas, irritación de mucosas y sensación de fatiga, que mejoran o incluso desaparecen al abandonar el edificio. La Organización Mundial de la Salud (OMS) estima que este problema afecta al 30% de los edificios modernos y causa molestias al 10-30% de sus ocupantes. OBJETIVO: Determinar si los síntomas manifestados por los trabajadores de un hospital terciario de la Comunidad de Madrid se corresponden con los síntomas que definen el SEE. Material y MÉTODO: Estudio descriptivo transversal. Se pasó un cuestionario a un grupo de trabajadores, seleccionados de forma aleatoria y voluntaria. RESULTADOS: Se recogieron 207 cuestionarios, 164 (79,2%) de mujeres y 43 (20,8%) de hombres. La edad media fue 41,4 años, 42,6 en mujeres y 36,6 en hombres (p< 0,01). Se encontró reagrupamiento de casos en algunas áreas del hospital (laboratorios y quirófanos) y se midieron condiciones ambientales: humedad 23-26% (valores recomendados superiores al 30%) y temperatura normal. Se encontraron 92 casos (44,4%) con síntomas que definen el SEE. CONCLUSIONES: El edificio en el que se desarrolla nuestro estudio cumple los criterios que se establecen en la definición de SEE

INTRODUCTION: Sick Building Syndrome (SBS) has more incidence of headache, irritation of mucous tissues and fatigue among workers. These symptoms get better or even disappear when workers leave the building. OBJECTIVES: The main aim of our research project was to check if the symptoms that some workers of one Tertiary Hospital in the Community of Madrid showed were those of SBS. Material and METHOD: For that purpose, we carried out a "cross-sectional descriptive study" through a questionnaire completed by staff members of the hospital both randomly selected and willing to take part. RESULTS: 207 questionnaires were collected, 164 (79.2%) of women and 43 (20.8%) of men. The average age was 41.4 years, 42.6 in women and 36.6 in men (p <0,01). More cases were found in certain areas of the hospital (laboratories and operating theaters). We were measured environmental conditions were measured: humidity 23 to 26% (recommended values above 30%) and normal temperature. 92 cases (44.4%) were found with symptoms that define the ESS (> 20% of those studied)

¿Qué hacemos ante un brote de escabiosis en un hospital? / What we do in front of a scabies outbreak in a hospital setting?

La escabiosis o sarna es una enfermedad de la piel producida por Sarcoptes scabiei; puede ir aumentando el número de casos, hasta llegar a producir verdaderas epidemias1. Se procede a describir las actuaciones del Servicio de Prevención de Riesgos Laborales de un hospital ante un brote de escabiosis ocurrido en una planta de hospitalización, con afectación de trabajadores sanitarios, tras el contacto con un paciente fuente (sospecha clínica y epidemiológica de escabiosis)

The scabies is a skin disease produced by Sarcoptes scabiei; it has been an increase on the number of cases, reaching eventually an epidemic level. We proceed to describe the measures taken by the laboral risk prevention service of a hospital against an outbreak of scabies happened in the hospitalization floor, with infection of the hospital workers after having contact with a source patient (clinic and epidemiologic scabies is suspected)
