Background: In a context of increasing demand and pressure on the public health expenditure, appropriateness of colonoscopy indications is a topic of discussion. The objective of this study is to evaluate the appropriateness of colonoscopy requests performed in a primary care (PC) setting in Catalonia. Methods: Cross-sectional descriptive study. Out-patients >14 years of age, referred by their reference physicians from PC or hospital care settings to the endoscopy units in their reference hospitals, to undergo a colonoscopy. Evaluation of the appropriateness of 1440 colonoscopy requests issued from January to July 2011, according to the EPAGE-II guidelines (European Panel on the Appropriateness of Gastrointestinal Endoscopy). Results: The most frequent indications of diagnostic suspicion requests were: rectal bleeding (37.46 %), abdominal pain (26.54 %), and anaemia study (16.78 %). The most frequent indications of disease follow-up were adenomas (58.1 %), and CRC (31.16 %). Colonoscopy was appropriate in 73.68 % of the cases, uncertain in 16.57 %, and inappropriate in 9.74 %. In multivariate analysis, performed colonoscopies reached an OR of 9.9 (CI 95 % 1.16-84.08) for qualifying as appropriate for colorectal cancer (CRC) diagnosis, 1.49 (CI 95 % 1.1-2.02) when requested by a general practitioner, and 1.09 (CI 95 % 1.07-1.1) when performed on women. Conclusions: Appropriateness of colonoscopy requests in our setting shows a suitable situation in accordance with recognized standards. General practitioners contribute positively to this appropriateness level. It is necessary to provide physicians with simple and updated guidelines, which stress recommendations for avoiding colonoscopy requests in the most prevalent conditions in PC.

Objectives: To calculate the prevalence of hypovitaminosis D in subjects aged 85 years old and to study the relationship between some common geriatric evaluation scales and vitamin D status. Design: Prospective cohort study. Setting: A community-based study. Participants: 312 subjects aged 85 years old. Measurements: Geriatric assessment was based on comorbidity, functional status according to the Barthel Index (BI) and Lawton Index (LI), cognitive status measured by the Spanish version of the Mini-Mental State Examination (MEC), nutritional risk according to the Mini Nutritional Assessment (MNA), and gait using the Tinetti Gait Scale. Serum 25(OH)D concentrations were used to assess vitamin D status. Hypovitaminosis D was considered as < 25 ng/ml and deficiency <11 ng/ml. Results: Mean serum 25(OH)D level was 28 ± 30 ng/ml. The prevalence of hypovitaminosis D was 52.5% (38.1% insufficiency and 14.4% deficiency). Men had higher levels than women (32.2 ± 44 vs. 25.2 ± 25 ng/ml; p=0.04). The bivariate analyses identified an association between MNA scores and hypovitaminosis D, and showed that females ande participants with poor BI, Tinetti and MNA scores were associated with deficiency. Logistic regression analysis confirmed a significant association between poor MNA scores and both hypovitaminosis D (p<0.04, OR 1.066, 95% CI 1.002-1.135) and vitamin D deficiency (p<0.0001, OR 1.192, 95% CI 1.099-1.293). Conclusions: More than half the population aged 85 years has a vitamin D deficit and 14.4% show a deficiency. A lower score on the MNA scale is associated with a greater likelihood of having lower vitamin D serum values. [ABSTRACT FROM AUTHOR]

A cross-sectional study was conducted to evaluate the utility of a commercial enzyme immunoassay (EIA) as a screening test for detecting HIV-1 antibody in urine in a population at risk for HIV infection in Catalonia, Spain. Paired urine and serum samples were collected consecutively from 99 patients who attended two drug-dependency treatment centres and 151 patients who attended a sexually transmitted diseases (STD) clinic in Barcelona. Antibodies against HIV in urine samples were detected using the Calypte HIV-1 Urine EIA (Calypte Biomedical Corporation, Berkeley, CA, USA) and confirmed by urine-based Western blot (WB) analysis. Sera were analysed using Bioelisa HIV-1+2 EIA (Biokit Laboratories, Barcelona, Spain), and the results were verified using serum-based WB analysis. Results of both urine and serum testing were available for 246 of 250 participants. For 52 individuals the results of both urine and serum testing were positive and for five the results were discordant (2 with urine-negative/serum-positive results and 3 with urine-positive/serum-negative results). The respective sensitivity and specificity values obtained for the urine EIA were 100% and 96.2% for intravenous drug users (IDUs) and 80% and 99.3% for persons attending the STD clinic. According to the 1997 UNAIDS/WHO strategy I recommendations, these values are acceptable for surveillance purposes, particularly in populations with a high prevalence of HIV infection.

Objective: The aim of this study was to assess the efficacy of an electronic reminder in primary healthcare in patients diagnosed with an indicator condition (IC) to improve HIV screening., Methods: We developed a prospective interventional study in 51 primary healthcare centres in Barcelona randomly assigned into one of two study groups: control and alert. Between June 2018 and May 2019, an electronic reminder appeared in the electronic medical record each time a diagnosis of an IC in patients aged 16-65 years was registered in the alert group. We assessed HIV testing rates within 4 months following the diagnosis of an IC., Results: In all, 13 000 patients were diagnosed with at least one IC. HIV testing was more likely in the alert group than in the control group. The electronic reminder multiplied the odds of being tested in men by 1.26 [95% confidence interval (CI): 1.04-1.52, p = 0.019], by 1.77 (95% CI: 1.33-2.38, p < 0.001) among patients aged < 50 years , and by 1.51 (95% CI: 1.20-1.92, p < 0.001) in diagnoses of IC other than a sexually transmitted infection (STI) or an AIDS-defining illness. Five (0.08%) cases of HIV were detected in the control group and 10 (0.17%) in the alert group., Conclusions: Implementing an electronic reminder had a positive impact on HIV screening rates in patients diagnosed with an IC. The alert was more effective among older patients, those living in less socioeconomically deprived neighbourhoods, and those with an IC other than an STI or an AIDS-defining illness., (© 2022 British HIV Association.)

Objectives: To evaluate co-infection of Strongyloides stercoralis and Trypanosoma cruzi and to assess eosinophilia as a screening test for the detection of S. stercoralis infection in patients with Chagas disease (CD)., Methods: A retrospective diagnostic validation study was performed on serum samples from primary care patients diagnosed with CD in the southern Barcelona metropolitan area. All samples with eosinophilia (n = 87) and a random sample of non-eosinophilic sera (n = 180) were selected. Diagnosis of CD was based on positive serology by means of two tests: ORTHO® T. cruzi ELISA test, and BIO-FLASH® Chagas or Bioelisa CHAGAS. SCIMEDX ELISA STRONGY-96 was used to diagnose strongyloidiasis., Results: Strongyloides stercoralis serology was positive in 15% of patients of whom 95% showed eosinophilia, vs. 21% of those with negative serology (P < 0.001), with differences in the mean eosinophil count (0.49 vs. 0.27 × 10 9 /l). Only 1.1% of patients with CD but without eosinophilia presented positive serology for S. stercoralis, whereas 44% of patients with CD and eosinophilia did (P < 0.001). Sensitivity and specificity values for eosinophilia were thus 95% and 79%, respectively. PPV was 42.5% and NPV, 98.9%., Conclusions: The prevalence of co-infection by T. cruzi and S. stercoralis is not negligible and has probably been underestimated for years in many areas, due to frequently subclinical infections. Therefore, serology seems mandatory for these patients and the use of eosinophilia as initial screening could facilitate the task, decreasing the number of analyses to be performed., (© 2019 John Wiley & Sons Ltd.)

Objective: To study the relationship between maternal affective disorders (AD) before and during pregnancy, and pre-term birth., Design: Retrospective observational study., Location: Sexual and reproductive health units at the Institut Català de la Salut (ICS) in Catalonia, Spain., Participants: Pregnant women with a result of live-born child from 1/1/2012 to 30/10/2015., Interventions: Data were obtained from the ICS Primary Care electronic medical record., Main Measurements: Diagnosis of AD before and during pregnancy, months of pregnancy, and possible confusion factors were collected. Descriptive statistical analysis (median, interquartile range, and absolute and relative frequency), bivariate analysis (Wilcoxon test and Chi-square test), and multivariate analysis (logistic regression) were performed., Results: 102,086 women presented valid information for the study. Prevalence of AD during pregnancy was 3.5% (4.29% in pre-term and 3.46% in term births; p<0.004). Pregnant women with pre-term births presented a higher age, smoking habit, lower inter-pregnancy interval, and a lower socio-economic status. Pre-term birth was significantly associated to previous history of stress and dissociative disorder (SDD), anxiety, obsessive-compulsive disorder (OCD) and eating disorders (ED), and use of antidepressants. It was also associated to abuse of alcohol, smoking, and use of psychoactive substances, as well as SDD, ED, use of antipsychotics, and divorce during pregnancy. Multivariate analysis confirmed the relationship between pre-term birth and history of AD, SDD, ED, and smoking, but not with AD during pregnancy., Conclusions: Examining the previous history of SDD and ED in pregnant women, and SDD, and ED during pregnancy is highly relevant to avoid pre-term birth., (Copyright © 2018 The Authors.

Introduction: Mother-to-child transmission (MTCT) is relevant in the global epidemiology of human-immunodeficiency virus (HIV), as it represents the main route of infection in children. The study objectives were to determine the rate of HIV-MTCT and its epidemiological trend between the Spanish-born and immigrant population in Catalonia in the period 2000-2014., Methods: A prospective observational study of mother-child pairs exposed to HIV, treated in 12 hospitals in Catalonia in the period 2000-2014. HIV-MTCT rate was estimated using a Bayesian logistic regression model. R and WinBUGS statistical software were used., Results: The analysis included 909 pregnant women, 1,009 pregnancies, and 1,032 children. Data on maternal origin was obtained in 79.4% of women, of whom 32.7% were immigrants, with 53.0% of these from sub-Saharan Africa. The overall HIV-MTCT rate was 1.4% (14/1,023; 95% CI; 0.8-2.3). The risk of MTCT-HIV was 10-fold lower in women with good virological control (P=.01), which was achieved by two-thirds of them. The proportion of immigrants was significantly higher in the period 2008-2014 (P<.0001), for the HIV-diagnosis (P<.0001), and antiretroviral administration (P=.02) during pregnancy, and for undetectable viral load next to delivery (P<.001). There were no differences in the rate of MTCT-HIV among Spanish-born and immigrant women (P=.6)., Conclusions: There is a gradual increase in HIV pregnant immigrants in Catalonia. Although most immigrant women were diagnosed during pregnancy, the rate of MTCT-HIV was no different from the Spanish-born women., (Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Introduction: The information available on antibiotic resistance patterns are generally based on specimens from hospitalised individuals. This study was aimed at evaluating the antibiotic resistance rate of nasal carriage strains of Staphylococcus aureus and Streptococcus pneumoniae in healthy individuals, in accordance with age and gender, attended in Primary Care Centres (PCC)., Design: Cross-sectional study., Setting: Seven PCC in the Barcelona area., Participants: Healthy nasal carriers aged 4years or more who did not present with any sign of infectious disease, and had not taken any antibiotic or had been hospitalised in the previous 3months., Main Measurements: A total of 3,969 nasal swabs valid for identification were collected between 2010 and 2011 and were sent to one central microbiological laboratory for isolation of both pathogens. Resistance to common antibiotics was determined on the basis of the current European Committee on Antimicrobial Susceptibility Testing guidelines on cut-off points., Results: The prevalence of methicillin-resistant S.aureus was 1.3% (95%CI: 0.5-2.1%), with resistance rates of 87.1% to phenoxymethylpenicillin and 11.6% to azithromycin, with no significant differences with age and gender. A total of 2.4% (95CI%: 0.1-4.7%) of the pneumococcal strains were highly resistant to both phenoxymethylpenicillin and macrolides, whereas the highest resistance rates were to cefaclor (53.3%), followed by tetracycline (20%) and cefuroxime (12.1%)., Conclusions: These pathogens have lower resistance rates in the community than in the hospital setting. Primary Care physicians must be more aware of the current antimicrobial resistance, in order to ensure prudent use of antibiotics., (Copyright © 2017 Elsevier España, S.L.U. All rights reserved.)

Background: Studies of the prevalence of HIV in sentinel populations are one of the key strategies to monitor the HIV epidemic. We describe HIV prevalence trends and identify differences across time in the sociodemographic characteristics of HIV-infected women giving birth in Catalonia., Methods: We used dried blood specimens, residual to newborn screening, which have been collected in Catalonia every 2 months since 1994. The total number of samples obtained until 2009 and in 2013 represented half of yearly newborns. From 2010 to 2012, the total number of samples obtained represented a quarter of yearly newborns. We studied the prevalence by year and place of current residence (Barcelona-city, cities>200,000 inhabitants and cities ≤ 200,000 inhabitants) and by the mother's birth country. A total of 624,912 infants were tested for HIV antibodies from January 1994 to December 2013., Results: HIV prevalence trends among women giving birth in Catalonia decreased until 2007. Thereafter, there was a change to a steady trend until 2013. However, among foreign women giving birth and living in cities ≤ 200,000 inhabitants, the prevalence of HIV increased from 2007 to 2013., Conclusion: To ensure early identification and treatment of HIV-infected mothers, it is essential to maintain HIV surveillance programs and pre- and post-natal screening programs, both in Barcelona and in cities with 200,000 inhabitants or less, especially in immigrant women., (Copyright © 2014 SESPAS.

Objectives: To describe the prevalence of the risk of being undernourished in a community-dwelling population of 85-year-olds, and to study associated factors., Methods: A cross-sectional community-based survey of 328 inhabitants assigned to seven primary healthcare teams was carried out. Geriatric assessment was based on sociodemographic variables, the Barthel Index (BI), the Lawton Index (LI), the Spanish version of the Mini-Mental State Examination, the Charlson Comorbidity Index, chronic diseases, social risk measured by Gijon's Social-Familial Evaluation Scale, prescriptions and blood tests. Nutritional status was assessed using the Mini Nutritional Assessment (MNA). Participants were defined as being at risk of undernourishment when they had a MNA score above or equal to 23.5. A comparative analysis was carried out between patients with and without risk of being undernourished, and a multiple logistic regression analysis was carried out., Results: The prevalence risk of being undernourished was 34.5%. A statistically significant association was found with being female (OR 2.44, 95% CI 1.28-4.54), LI (OR 1.47, 95% CI 1.29-1.66), social risk (OR 1.15, 95% CI 1.02-1.29) and prescription drugs taken (OR 5.58, 95% CI 2.09-14.92). Cardiovascular prescription showed a protective association (OR 4.34, 95% CI 1.78-10.0). No statistical differences between the risks of being undernourished were found in the laboratory analysis., Conclusions: There is a high risk of being undernourished in 85-year-old subjects. This nutritional status was positively associated with being female, disability, increased social risk and a high number of prescription drugs, whereas there was a protective relationship with cardiovascular prescription. In evaluations of nutritional status in the community, a multidisciplinary assessment is more valid than analytical findings., (© 2013 Japan Geriatrics Society.)

This paper estimates the prevalence of human immunodeficiency virus (HIV) infections in women giving birth and women voluntarily terminating pregnancy over a period of sixteen years in Catalonia. Samples for HIV antibody detection were collected from the Neonatal Early Detection Programme for congenital metabolic diseases that covers 99% of infants born in Catalonia. The sampling method collected information of 50% of births every year and of all women attending three clinics for voluntary interruption of pregnancy. Using two sequential immunoassays we analysed unlinked anonymous blood spot samples from 549,689 newborns between 1994 and 2009 and from 31,904 women who voluntarily interrupted pregnancy between 1999 and 2006. HIV prevalence among women giving birth decreased from 3.2 per 1,000 in 1994 to 1.7 per 1,000 in 2009 (p<0.01) and the mean age of infected mothers increased from 26 years in 1994 to 32 years in 2009 (p=0.001). A decrease in HIV prevalence was also observed in women voluntarily terminating pregnancy, from 2.3 per 1,000 in 1999 to 1.0 per 1,000 in 2006 (p<0.01). In contrast, estimated HIV prevalence in mothers born outside Spain increased from 2.2 per 1,000 in 2002 to 3 per 1,000 in 2009 (p<0.01) and their average age increased from 27 years in 2003 to 31 years in 2009 (p<0.01).

Objectives: The main aim of this study was to identify the experiences of professionals in nongovernmental organizations (NGO) in Catalonia (Spain) working in HIV/AIDS prevention and control activities and potential areas of improvement of these activities and their evaluation. A further aim was to characterize the experiences, knowledge and practices of users of these organizations with regard to HIV infection and its prevention., Methods: A phenomenological qualitative study was conducted with the participation of both professionals and users of Catalan nongovernmental organizations (NGO) working in HIV/AIDS. Theoretical sampling (professional) and opportunistic sampling (users) were performed. To collect information, the following techniques were used: four focus groups and one triangular group (professionals), 22 semi-structured interviews, and two observations (users). A thematic interpretive content analysis was conducted by three analysts., Results: The professionals of nongovernmental organizations working in HIV/AIDS adopted a holistic approach in their activities, maintained confidentiality, had cultural and professional competence and followed the principles of equality and empathy. The users of these organizations had knowledge of HIV/AIDS and understood the risk of infection. However, a gap was found between knowledge, attitudes and behavior., Conclusions: NGO offer distinct activities adapted to users' needs. Professionals emphasize the need for support and improvement of planning and implementation of current assessment. The preventive activities of these HIV/AIDS organizations are based on a participatory health education model adjusted to people's needs and focused on empowerment., (Copyright © 2010 SESPAS.

Background: Primary health care (PHC) professionals play a key role in population screening of colorectal cancer. The purposes of the study are: to assess knowledge and attitudes among PHC professionals with regard to colorectal cancer screening, as well as the factors that determine their support for such screening., Methods: Questionnaire-based survey of PHC physicians and nurses in the Balearic Islands and in a part of the metropolitan area of Barcelona., Results: We collected 1,219 questionnaires. About 84% of all professionals believe that screening for colorectal cancer by fecal occult blood test (FOBT) is effective. Around 68% would recommend to their clients a colorectal cancer screening program based on FOBT and colonoscopy. About 31% are reluctant or do not know. Professionals perceive the fear of undergoing a colonoscopy as the main obstacle in getting patients to participate, and the invasive nature of this test is the main reason behind their resistance to this program. The main barriers to support the screening program among PHC professionals are lack of knowledge (nurses) and lack of time (physicians). On multivariate analysis, the factors associated with reluctance to recommend colorectal cancer screening were: believing that FOBT has poor sensitivity and is complicated; that colonoscopy is an invasive procedure; that a lack of perceived benefit could discourage client participation; that only a minority of clients would participate; thinking that clients are fed up with screening tests and being unaware if they should be offered something to ensure their participation in the programme., Conclusions: Two in every three PHC professionals would support a population screening program for colorectal cancer screening. Factors associated with reluctance to recommend it were related with screening tests characteristics as sensitivity and complexity of FOBT, and also invasive feature of colonoscopy. Other factors were related with patients' believes.

Background: Non-occupational post-exposure prophylaxis for human immunodeficiency virus (HIV) infection is widely used, although there is little available scientific evidence to support its effectiveness. The aim of this study is to describe the characteristics of the persons exposed, types of exposures, antiretroviral treatment prescribed, and outcome of HIV infection in cases of non-occupational exposure in Spain., Method: The data used included all cases of accidental HIV exposure notified to the Non-occupational Post-exposure Prophylaxis Information System between January 2001 and December 2005. Non-occupational exposure to HIV was defined as accidental contact with blood and/or other biological fluids outside the healthcare setting., Results: A total of 993 cases of exposure were notified (569 men [57.3%]); median age was 30 years (range: 1-87). Exposure was sexual in 53.1%, parenteral in 39.8%, and other types in 7.2%. The source person was identified in 82.7% of cases. Antiretroviral treatment (ART) was prescribed in 528 cases (53.2%), with triple therapy in 68.2%. A total of 54.2% returned for the 6-month visit among patients receiving ART and 61.1% among those without this therapy (P < 0.05). One or more side effects developed in 135 (32.4%) cases, and there were 18 treatment interruptions (4.3%). Three seroconversions to HIV were notified (0.3%)., Conclusions: A national registry for monitoring non-occupational post-exposure prophylaxis to HIV is needed because of the high number of cases notified, the considerable incidence of side effects, and the difficulties of follow-up.

Objectives: We undertook a prospective study to estimate the prevalence of gestational diabetes mellitus (GDM) and associated risk factors in a cohort of 669 HIV-1 infected women., Methods: The O'Sullivan and glucose tolerance tests were performed during regular visits of 609 mothers., Results: The median age of the cohort was 30.7 years (range 16-44), with most women having had heterosexual contact (67%). The majority were in Centers for Disease Control (CDC) category A (71%) and 53% exhibited hepatitis C co-infection. Median viral load and CD4 count at third trimester were 545 cells/microL (range 139-1690 cells/microL) and 1.9 log (range 1.7-5.4), respectively. Seventy-four per cent of the patients were treated with highly active antiretroviral therapy (HAART), of whom 41% received a protease inhibitor (PI). An above-average prevalence of 7% [95% confidence interval (CI) 5.2-9.5] for positive GDM diagnosis was found. Risk factors associated with GDM in univariate analysis included older age, hepatitis C co-infection, stavudine and PI exposure. However, only older age [adjusted odds ratio (AOR) 1.09, 95% CI 1-1.1] and PI exposure (AOR 2.4, 95% CI 1-5.3) remained as independent risk factors for GDM development in multivariate analysis., Conclusions: In our cohort, the prevalence of GDM appears to be increased, with older age and PI exposure contributing as significant independent risk factors.

Background: to estimate the coverage of HIV testing during pregnancy in Catalonia, to identify factors associated with testing during pregnancy and to assess the recording of screening in medical records and the women's awareness about being tested., Methods: A survey was carried out in 2000 among pregnant women attending hospital, with face-to-face interview 24-48 hours post-delivery, and review of the medical records., Results: Out of 2,132 participants, 76% were from public and 24% from private hospitals. Medical records showed that 88.3% of the participants had a HIV test (94% in public, 71% in private hospitals), while for 3.7% and 18.5% in private and public, respectively, this information was not documented. Overall, 67% of women reported having been tested for HIV during that pregnancy, and unawareness of having been tested was detected in 10.7%. Educational level and prenatal care are determinants for being tested., Conclusion: Catalonia has a good coverage of HIV testing among childbearing women, although it is lower in private hospitals. Frequently prenatal HIV testing is not documented in medical records and women are unaware of it. Improving the prenatal care and tailoring these programmes to specific populations, like migrants or marginalized groups, will result in a better understanding of HIV prevention and in an increase in HIV testing before delivery.

Objectives: To identify and describe the factors that have led to new cases of HIV infection through mother-to-child transmission since the introduction of antiretroviral therapy in HIV-seropositive pregnant women (1997-2001) in Catalonia., Methods: Systematic review of cases identified in the pediatric services of all the hospitals in Catalonia., Results: Twenty-eight cases of pediatric HIV infection were identified: 9, 9, 8, 2 and 0 per year of birth from 1997 to 2001, respectively. Of 16 mothers with a diagnosis of known HIV infection before or during pregnancy, nine underwent antiretroviral prophylaxis during pregnancy (compliance was good in five, unknown in one and poor in one) and seven did not undergo prophylaxis (six refused it and no information was available in one). Of 12 mothers diagnosed after delivery, pregnancy was not monitored in five and was little or well-monitored in the remaining seven. Of mothers with well-monitored pregnancy, a serological HIV test was not performed in six and was negative in the first trimester in one., Conclusions: Mother-to-child transmission of HIV has decreased in the last few years in Catalonia, but infections have sometimes occurred through poor implementation of preventive measures. Pregnant women should be offered an HIV diagnostic test not only in the first trimester but also at the end of pregnancy if HIV exposure is suspected. In women with unmonitored pregnancies, rapid diagnostic tests for HIV should be used in the delivery room.

Objective: To describe the process performed in Catalonia (Spain) to design an information system for monitoring new cases of HIV infection., Methods: A survey was used to evaluate perception of the need for notification of HIV infection by health care professionals (n = 106), as well as their opinions of the various possibilities for the implementation of the notification system. As a result of this evaluation, a specific technical report defining the objectives and technical characteristics of the new notification system was produced. The feasibility of the system in health centres was evaluated through discussions with health care professionals, health authorities and Non-Governmental Organizations, and a second survey was designed to evaluate the use of a personal identification code (PIC) from the individual health card (IHC). This process took plabe between 1998 and 2000., Results: A total of 84.5% of the health care professionals believed that HIV notification should be mandatory and confidential; 90.4%, were of the opinion that notification would enable identification of the epidemiological characteristics of infected individualos, and 75% believed that these individuals would have to be identified by name. Finally, 66% of the health care professionals believed that the use of the PIC from the IHC would be feasible as the personal identifier in HIV notification. A final proposal was draw up and 1 January, 2001 was set as the date to initiate the pilot phase of the new HIV notification system., Conclusions: Most of the health care professionals surveyed expressed the need for notification of HIV infection, and for such notification to receive institutional endorsement. They also believed that, as with other diseases of individualized mandatory reporting, notification should be carried out with a single personal identifier. The information obtained from notification of HIV infection is essential for the optimal planning of preventive programs and the provision of health services. The main difficulties observed were that HIV infection has not been included among the diseases of mandatory reporting, as well as the low implantation of the PIC in the hospitals' clinical registries. All the sectors involved have an important role to play in creating the conditions necessary for the notification system of new cases of HIV infection to be feasible and useful.

Evidence is lacking on the possible efficacy and effectiveness of non-occupational postexposure prophylaxis (PEP). However, because of its biological plausibility, the use of antiretroviral (ARV) drugs to prevent the development of infection in certain cases of accidental or sporadic exposure has begun to be considered as common clinical practice. Previous studies performed in Spain have demonstrated both the demand and the prescription of ARV as PEP and especially the diversity and inconsistency in the criteria used. In this context, in April of 2000 the Centre for Epidemiological Studies on AIDS of Catalonia (CEESCAT) (Department of Health and Social Security of the Autonomous Government of Catalonia), in collaboration with the National AIDS Plan and the AIDS Study Group (GESIDA), promoted the creation of a working group for the drafting of recommendations for PEP against HIV outside the occupational health context. The recommendations have been made bearing in mind the exceptional character of the exposure, the time elapsed since exposure, as well as evaluation of the risk of infection according to the type of exposure and the information available on the source of infection. In addition, the recommendations include the immediate measures necessary, as well as the preventive measures and clinical follow-up required both for HIV and for other infectious agents. All PEP regimens should be started within 72 hours of exposure and appropriate daily doses of two nucleoside reverse transcriptase inhibitors (NRTIs) and a protease inhibitor (PI), or two NRTIs and a non-nucleoside reverse transcriptase inhibitor (NNRTIs), should be administered for four weeks, bearing in mind the pharmacological and clinical situation of the source person. These recommendations should be updated periodically.

Background: Swimming in rivers or lakes is a risk activity, in areas where the life cycle of schistosomiasis occurs. This report presents and analyzes the clinical presentation and epidemiological data of 80 Spanish travellers., Patients and Methods: Descriptive longitudinal and retrospective study that includes clinicoepidemiological and the laboratory data and imaging diagnosis. Patients were seen at the Section of Tropical Medicine, Hospital Clínic i Provincial, Barcelona., Results: Most patients acquired the infection in the Dogon country of Mall. 25% of them presented with symptoms related to the genital tract. In some groups, 45% of travellers that swam, contracted the infection. The most prevalent species diagnosed was S. haematobium and 10 travellers presented with mixed infections., Conclusions: The trip to the Dogon country should be considered as "a risk activity". Travellers Advice Clinics should include the subject of swimming in infected waters in their routine counselling. Genital tract localizations were registered for three species of schistosome. The classical clinical presentation of schistosomiasis in the endemic areas differs considerably from that seen in travellers.
