RESUMEN
UNLABELLED: Asthma drugs are amongst the most frequently used drugs in childhood, but international comparisons on type and indication of use are lacking. The aim of this study was to describe asthma drug use in children with and without asthma in the Netherlands (NL), Italy (IT), and the United Kingdom (UK). We conducted a retrospective analysis of outpatient medical records of children 0-18 years from 1 January 2000 until 31 December 2005. For all children, prescription rates of asthma drugs were studied by country, age, asthma diagnosis, and off-label status. One-year prevalence rates were calculated per 100 children per patient-year (PY). The cohort consisted of 671,831 children of whom 49,442 had been diagnosed with asthma at any time during follow-up. ß2-mimetics and inhaled steroids were the most frequently prescribed asthma drug classes in NL (4.9 and 4.1/100 PY), the UK (8.7 and 5.3/100 PY) and IT (7.2 and 16.2/100 PY), respectively. Xanthines, anticholinergics, leukotriene receptor antagonists, and anti-allergics were prescribed in less than one child per 100 per year. In patients without asthma, ß2-mimetics were used most frequently. Country differences were highest for steroids, (Italy highest), and for ß2-mimetics (the UK highest). Off-label use was low, and most pronounced for ß2-mimetics in children <18 months (IT) and combined ß2-mimetics + anticholinergics in children <6 years (NL). CONCLUSION: This study shows that among all asthma drugs, ß2-mimetics and inhaled steroids are most often used, also in children without asthma, and with large variability between countries. Linking multi-country databases allows us to study country specific pediatric drug use in a systematic manner without being hampered by methodological differences. This study underlines the potency of healthcare databases in rapidly providing data on pediatric drug use and possibly safety.

The Task-force in Europe for Drug Development for the Young (TEDDY) was established in 2005 to contribute to the promotion of safe and efficacious medicines for children in the context of the impending European Paediatric Regulation that finally came into force in January 2007. The project includes seven objectives and 12 Work-Packages encompassing the main aspects of the development and use of pediatric drugs. TEDDY represents a new entity in the pediatric pharmaceutical field, differing from a Scientific Society, a network for developing research or trials, or a consultative regulatory body. The ambition of TEDDY is to support the existing pediatric networks, societies, and regulatory bodies in performing innovative initiatives, including those in areas in which such undertakings would not be feasible without supportive action. To accomplish its aim, TEDDY has focused on three different actions: (i) increasing awareness about the Paediatric Regulation revolution; (ii) reaching consensus on terms and instruments to be used for common research; and (iii) favoring close relationships among different stakeholders and partners from different EU Member States. After 3 years of activities, many results have been produced by the Network: surveys, databases, expert opinions, and recommendations. Linking together different stakeholders, including industry and patient associations, as well as academia and research centers, the Network has contributed to increasing awareness and participation in the Paediatric Regulation. In addition, many papers detailing original results have either been published or submitted for publication in peer-reviewed journals. TEDDY is an original Network whose identity and role as a catalyzer of initiatives related to the use and development of pediatric drugs needs to be better clarified in the near future. Of particular importance is the need to reach consensus on best practices. The lack of a common view on pediatric research requirements among stakeholders across Member States remains the main challenge to be overcome.

OBJECTIVE: To examine the relationship between dietary patterns and metabolic syndrome. DESIGN: Population-based cross-sectional study. The K-means clustering method was used to identify dietary patterns and logistic regression models were used to compare the adjusted prevalence rates of metabolic syndrome factors, stratifying by obesity status. SETTING: The 1992-3 Italian Bollate Eye Study, a population-based survey carried out in the town of Bollate (Milan), Italy. SUBJECTS: A total of 1052 non-diabetic Italian subjects, 527 men and 525 women, aged 42-74 years. RESULTS: Five dietary clusters were identified: common, animal products, starch, vegetal/fat and vitamin/fibre. After adjusting for potential confounders, the starch group showed the highest prevalence of metabolic syndrome (36%) followed by the animal products group (30%); the vitamin/fibre (20%) and vegetal/fat groups (19%) showed the lowest prevalence. The starch group had more dyslipidaemia (higher TAG and lower HDL cholesterol levels) and the animal products group had a higher prevalence of impaired fasting glucose. The vitamin/fibre group had the lowest prevalence of abdominal obesity. The beneficial effect of the vegetal/fat and vitamin/fibre dietary patterns seemed stronger among the obese. CONCLUSIONS: Our results confirm the deleterious effect of a very-low-fat, high-carbohydrate diet and also of high intakes of animal products. The consumption of a diet high in vegetal fats or rich in fruits and vegetables is associated with a healthier metabolic profile. Reducing obesity is essential to prevent metabolic syndrome, but even among the obese dietary habits are important for preserving healthy lipid and glycaemic profiles.

OBJECTIVES: To study sexual activity, the prevalence of sexual dysfunction, and related help-seeking behaviour patterns among middle-aged and older people in the UK and Europe. SUBJECTS AND METHODS: A telephone survey was conducted using a structured questionnaire covering demographics, health, relationships, and sexual behaviour, attitudes and beliefs. In the UK, 1500 individuals completed the survey. RESULTS: Overall, 69% of men and 56% of women reported having sexual intercourse during the past year. The most common male sexual problems, i.e. early ejaculation (20%) and erectile dysfunction (18%), were more common in the UK than in other European regions. The most common female sexual problems, i.e. a lack of sexual interest (34%) and a lack of pleasure in sex (25%), were also more common in the UK than in other European regions. Only 26% of men and 17% of women had discussed their sexual problem(s) with a doctor. CONCLUSION: Many people in the UK maintain sexual interest and activity into middle age and beyond. Although they experience sexual problems, few seek medical help. This might be because they do not perceive such problems as serious or sufficiently upsetting, and/or are not aware of available treatments.

PURPOSE: To identify and describe European health care databases that can be used for pediatric pharmacoepidemiological research. METHODS: A web-based survey was conducted among all European databases that were listed on the website of the International Society of Pharmacoepidemiology (ISPE) and/or known by an expert group. The survey comprised of questions regarding (a) the nature of the database, (b) database size, (c) demographic, clinical and drug related data provided, (d) cost, and (e) accessibility of the database. RESULTS: A total of 25 data sources from 12 European countries were identified and invited to participate in the survey. Responses were obtained from 21 (84%) databases located in 10 different European countries. Seventeen databases were included in the assessment comprising a total of at least 9 million children aged 0-18 years. The majority of databases are based on outpatient data and all keep either prescription or drug dispensing data. Ten databases are based on electronic patient records from primary care physicians and five databases are predominantly claims oriented. Three databases do not belong to either of the above mentioned categories. Almost all of the databases can be used for pediatric drug utilization studies. For drug safety studies it is more appropriate to use electronic patient record databases because of the available clinical information and the potential to obtain additional information. CONCLUSIONS: There are many European healthcare databases providing an enormous potential for pediatric pharmacoepidemiological research. Future research should focus on methods to bring data from different databases together to use the full capacity effectively.

BACKGROUND: Depression and erectile dysfunction (ED) have a complex and bi-directional relationship. We examined the relationships between erectile dysfunction and depressive symptoms or diagnosed depression, sexual activity and sexual satisfaction. METHODS: A population survey of men aged 40-70 years was carried out in Brazil, Italy, Japan and Malaysia in 1997-1998. A questionnaire was used to collect life style, sexual behaviors and medical data. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. ED was classified as moderate or complete if the men reported they were "sometimes" or "never" able to achieve and maintain an erection satisfactory for sexual intercourse. Only men with a sexual partner and not taking psychoactive drugs were considered. RESULTS: Diagnosed depression was reported by 2.0% of the men, depressive symptoms by 21.0%. The prevalence of moderate or complete ED was 17.8%. Sexual satisfaction related to the frequency of sexual intercourse and inversely related to depressive symptoms. Depressive symptoms were positively associated with being single (odds ratio [OR] 1.7), widowed, separated or divorced (OR 2.2), moderate or complete ED (1.8), heart disease (1.6) and smoking (1.6), and negatively associated with age, physical activity and frequency of sexual intercourse. LIMITATIONS: Cross-sectional studies cannot establish a temporal cause-effect relationship. However, the confirmation of known associations reassures about the validity of the original findings. CONCLUSIONS: The findings suggest that depressive symptoms are linked to ED by the mediation of decreased sexual activity and the dissatisfaction generated by the inability to have a healthy sexual life.

OBJECTIVE: To provide an overview of drug use in children in three European countries. DESIGN: Retrospective cohort study, 2000-5. SETTING: Primary care research databases in the Netherlands (IPCI), United Kingdom (IMS-DA), and Italy (Pedianet). PARTICIPANTS: 675 868 children aged up to 14 (Italy) or 18 (UK and Netherlands). MAIN OUTCOME MEASURE: Prevalence of use per year calculated by drug class (anatomical and therapeutic). Prevalence of "recurrent/chronic" use (three or more prescriptions a year) and "non-recurrent" or "acute" use (less than three prescriptions a year) within each therapeutic class. Descriptions of the top five most commonly used drugs evaluated for off label status within each anatomical class. RESULTS: Three levels of drug use could be distinguished in the study population: high (>10/100 children per year), moderate (1-10/100 children per year), and low (<1/100 children per year). For all age categories, anti-infective, dermatological, and respiratory drugs were in the high use group, whereas cardiovascular and antineoplastic drugs were always in the low use group. Emollients, topical steroids, and asthma drugs had the highest prevalence of recurrent use, but relative use of low prevalence drugs was more often recurrent than acute. In the top five highest prevalence drugs topical inhaled and systemic steroids, oral contraceptives, and topical or systemic antifungal drugs were most commonly used off label. CONCLUSION: This overview of outpatient paediatric prescription patterns in a large European population could provide information to prioritise paediatric therapeutic research needs.

We conducted a telephone survey during 2001-2002 to investigate sexual behavior, sexual dysfunction, and related help-seeking behavior in five Anglophone countries. In total, 5,998 individuals (2,992 men and 3,006 women) aged 40-80 years in the United States, Canada, the United Kingdom, Australia, and New Zealand completed the survey. The majority of subjects were sexually active, and although many men and women had experienced sexual dysfunctions, few had sought medical care for these dysfunctions. Further investigation is required to determine whether national differences in the prevalence of sexual dysfunctions are due to genetic predisposition, health factors, cultural perception or socioeconomic situation.

To study the sexual activity and the prevalence of sexual dysfunctions and related help seeking behaviour, among people in Europe aged 40-80 years. A telephone survey was carried out in 2001-2002 in Sweden, the UK, Belgium, Germany, Austria, France, Spain and Italy, of 4,977 men and 5,023 women, using a structured, standardized questionnaire Eighty-three percent of men and 66% of women had sexual intercourse during the year preceding the interview. The sexual dysfunctions most frequently reported were early ejaculation (11%) and erectile dysfunction (8%) in men; and a lack of sexual interest (18%), an inability to reach orgasm (13%) and lubrication difficulties (11%) in women. Of the 23% of men and 32% of women who reported sexual dysfunction, 26% had consulted a physician, with considerable between-country differences. Sexual activity is widespread among adult middle-aged and elderly people, but many experience sexual dysfunctions and few seek medical care.

Subjective sexual well-being refers to the cognitive and emotional evaluation of an individual's sexuality. This study examined subjective sexual well-being, explored its various aspects, examined predictors across different cultures, and investigated its possible associations with overall happiness and selected correlates, including sexual dysfunction. Data were drawn from the Global Study of Sexual Attitudes and Behaviors, a survey of 27,500 men and women aged 40-80 years in 29 countries. The cross-national variation of four aspects of sexual well-being (the emotional and physical satisfaction of sexual relationships, satisfaction with sexual health or function, and the importance of sex in one's life) was explored using cluster analysis, and relationships among sexual well-being, general happiness, and various correlates were examined using ordinary least squares regression and ordered logistic regression. Results from the cluster analysis identified three clusters: a gender-equal regime and two male-centered regimes. Despite this cultural variation, the predictors of subjective sexual well-being were found to be largely consistent across world regions.

BACKGROUND AND OBJECTIVE: Results from a relatively small case-control study recently showed that niflumic acid increases the risk of serious mucocutaneous reactions in children. As a consequence, the Italian Ministry of Health sent a "Dear Doctor" letter in June 2001 to warn pediatricians about the alleged adverse effects. The objective of this study was to estimate and compare the incidence of mild and severe mucocutaneous reactions among children using niflumic acid, other nonsteroidal antiinflammatory drugs (NSAIDs), or nonopioid analgesics. DESIGN: Retrospective cohort study. SETTING: Italy is one of the few countries in which a specific primary care system is devoted to children up to 14 years of age: every child is registered at birth and receives free medical care from 1 of the approximately 6000 family pediatricians working for the National Health Service. This study was conducted with the Pedianet network of Italian family pediatricians who use computerized electronic patient records for routine care; 185 pediatricians participated in the study. The patient records comprise information on demographics, diagnoses, symptoms, prescriptions, referrals, laboratory examinations, and hospitalizations. PARTICIPANTS: Children aged 0 to 14 years and registered with 1 of the collaborating pediatricians between January 1, 1998, and May 31, 2001. MAIN OUTCOME MEASURES: The incidence rate of severe (hospitalized or referred) and mild mucocutaneous reactions (exanthema, disseminated or localized pruritus, urticaria, angioedema, fixed eruption, dermatitis, erythema multiforme, vesicles, bullae, pustules, toxic epidermal necrolysis, purpura, and vasculitis) was estimated during use of niflumic acid, other NSAIDs, or nonopioid analgesics. For each episode of drug use, the following covariates were assessed: age, gender, region, year, indication for study drug, use of antibiotics, antimycotic agents, glucocorticoids, and other NSAIDs. Multivariate Poisson regression analysis was used to estimate the adjusted relative risk of mucocutaneous disorders during use of niflumic acid compared with use of other NSAIDs or use of acetaminophen alone. RESULTS: The population included 193727 children, 45351 of whom received at least 1 of the study drugs. The most frequently prescribed drugs were niflumic acid, acetaminophen, and propionic acid derivatives (ketoprofen and flurbiprofen). Users of niflumic acid (n = 32150) were younger and slightly more often had otitis media or upper respiratory tract infections as an indication compared with the other NSAIDs. During use of the various study drugs we identified 1451 mild mucocutaneous events and 42 severe reactions. The incidence rates of severe and mild mucocutaneous reactions after the administration of any study drug were 10.3 per 100000 exposure person-days and 3.7 per 1000 exposure person-days, respectively. Both incidence rates decreased strongly with increasing age. In comparison with other NSAIDs, the adjusted relative risks of niflumic acid were 0.5 (95% confidence interval: 0.23-1.27) for severe and 0.9 (95% confidence interval: 0.79-1.11) for mild mucocutaneous reactions. The use of acetaminophen as a reference category instead of other NSAIDs, restriction of the children to those who received NSAIDs for respiratory tract infections, or restriction to those who did not use antibiotics never revealed an increased risk of serious or mild mucocutaneous reactions during use of niflumic acid. CONCLUSIONS: In comparison with other NSAIDs or acetaminophen, niflumic acid is not associated with an increased risk of severe or mild mucocutaneous reactions in children. This was true for the different age groups and various types of mucocutaneous reactions, was independent of the concomitant use of antibiotics, and was not sensitive to changes in our assumptions regarding exposure and outcomes.

OBJECTIVE: To study sexual activity, the prevalence of sexual dysfunction and related help-seeking behaviour among middle-aged and elderly people in Asia. SUBJECTS AND METHODS: A random population survey was carried out in 2001-2002 among urban residents aged 40-80 years in China, Taiwan, South Korea, Japan, Thailand, Singapore, Malaysia, Indonesia and The Philippines, with interviews based on a standardized questionnaire covering demographic details, health, relationships, and sexual behaviours, attitudes and beliefs. An intercept method of sampling was used in all countries except Japan, where questionnaires were mailed to a sample drawn from telephone directories. Sexual dysfunction was defined as persistent sexual problems. RESULTS: The questionnaire was completed by 6700 people (3350 men and 3350 women), giving a response rate of 27%. Across all countries, 82% of men and 64% of women had engaged in sexual intercourse during the year preceding the interview. Most of the respondents considered satisfactory sex an essential means of maintaining a relationship. More than 20% of men and 30% of women complained of having at least one sexual dysfunction, although there were marked variations among the countries. The sexual dysfunctions most frequently reported were early ejaculation (20%; 95% confidence interval, CI, 18-21) and erectile dysfunction (15%, 14-17) among men; and a lack of sexual interest (27%, 25-29), lubrication difficulties (24%, 22-25), and an inability to reach orgasm (23%, 22-25) among women. Of the 948 men and 992 women who were sexually active and reported sexual dysfunctions, 45% did sought no help or advice and only 21% sought medical care. CONCLUSION: Men and women in Asian countries continue to show sexual interest and activity into middle age and beyond. Although sexual dysfunction is prevalent in this age group, several sociocultural and economic factors appear to be preventing individuals from seeking medical help for these problems.

OBJECTIVES: To estimate the incidence of erectile dysfunction (ED) in Brazilian men 40 to 69 years old at study entry during an average 2-year follow-up and study the effect of age, socioeconomic status, and medical conditions on the risk of developing ED. METHODS: We analyzed data from a randomly sampled cohort of men living in Salvador, Bahia (Brazil), a racially diverse city with a population of 2.3 million. A total of 602 men completed the baseline interview in 1998 and 501 completed follow-up in 2000. The analysis sample consisted of 428 (83.4%) of 513 men without ED at baseline. The men were interviewed in person, using a standardized questionnaire, and ED was assessed by a single global self-rating question. RESULTS: The crude incidence rate for ED was 65.6 cases per 1000 person-years (95% confidence interval 49.6 to 85.2). The incidence rate increased with age and was 33.3, 53.7, and 189.5 cases per 1000 person-years for men 40 to 49, 50 to 59, and 60 to 69 years old, respectively. The age-adjusted risk of developing new-onset ED was higher for men with lower education, diabetes, hypertension, and benign prostatic hyperplasia. Population projections for men 40 to 69 years old suggest that approximately 68,600 new cases of ED in Bahia and 1,025,600 in Brazil would be expected annually. CONCLUSIONS: The incidence of ED in Brazilian men was 2.5-fold higher than that in the Massachusetts Male Aging Study (26/1000 person-years) and increased with age, lower education, diabetes, hypertension, and benign prostatic hyperplasia.

BACKGROUND: Interest in the incidence of varicella (chickenpox) has increased since the discovery of an effective vaccine, but calculations to date have incorrectedly ignored the question of susceptibility. METHODS: We studied the occurrence of varicella in Italy on the basis of 33,343 children (age 0-14 years) cared for by 35 pediatricians between 1 October 1997 and 30 September 1998. The life-table technique was used to calculate the number of susceptible children. On this basis, we estimated the corrected age-specific and cumulative incidence. RESULTS: We identified 1749 cases among the estimated 21,783 susceptible children, for a crude incidence of 8.0% (95% confidence interval [CI] = 7.7-8.4). The rate age-standardized to the Italian population 0-14 years old was 6.8 (CI = 6.5-7.2). The incidence was more than 16% among children age 3-4 years and more than 4% for those age 1-10 years. Comparison of the usual method and our corrected method showed that the uncorrected method underestimates the crude annual incidence (5.2% 8.0%), shifts the peak incidence to earlier ages, and underestimates cumulative incidence (at age 14, 49% 67%). CONCLUSIONS: The use of our corrected method provides more valid estimates of the incidence of varicella than the ones that are currently available. Corrected estimates should be preferred to uncorrected ones in models to study the cost-effectiveness of universal vaccination against varicella.

OBJECTIVES: To assess the importance of sex and the prevalence of sexual dysfunction among middle-aged and older adults throughout the world. Increasing life expectancy has been accompanied by improvements in the health of the middle-aged and elderly, but little is known about how this has affected their sexual experience. METHODS: Data were collected in 29 countries from 27,500 men and women aged 40 to 80 years using a standardized questionnaire (self-completed or by interview). Sexual dysfunction was defined as frequent and persistent problems. They included early ejaculation and erectile difficulties in men, lubrication difficulties and pain during intercourse in women, and a lack of sexual interest, an inability to achieve orgasm, and a feeling of unpleasurable sex in both. RESULTS: More than 80% of the men and 65% of the women had had sexual intercourse during the past year. Of these subjects, the most common dysfunctions were early ejaculation (14%) and erectile difficulties (10%) among the men and a lack of sexual interest (21%), inability to reach orgasm (16%), and lubrication difficulties (16%) among the women. Overall, 28% of the men and 39% of the women said that they were affected by at least one sexual dysfunction. CONCLUSIONS: The results of our study indicate that sexual desire and activity are widespread among middle-aged and elderly men and women worldwide and persist into old age. The prevalence of sexual dysfunctions was quite high and tended to increase with age, especially in men. Although major between-country differences were noted, this global study revealed some clear and consistent patterns.

OBJECTIVES: To measure the prevalence of erectile dysfunction (ED) in community-based populations in Brazil, Italy, Japan, and Malaysia and to study its association with the demographic characteristics, medical conditions, and health-related behavior. METHODS: In each country, a random sample of approximately 600 men aged 40 to 70 years was interviewed using a standardized questionnaire. All the data were self-reported. ED was assessed by the participants' "ability to attain and maintain an erection satisfactory for sexual intercourse," and the men were classified as not having ED if they answered "always" and as having mild, moderate, or complete ED if they answered "usually," "sometimes," or "never," respectively. RESULTS: The age-adjusted prevalence of moderate or complete ED was 34% in Japan, 22% in Malaysia, 17% in Italy, and 15% in Brazil. The overall age-specific prevalence of moderate or complete ED was 9% for men aged 40 to 44 years, 12% for 45 to 49 years, 18% for 50 to 54 years, 29% for 55 to 59 years, 38% for 60 to 64 years, and 54% for those 65 to 70 years. The increased risk of ED was associated with diabetes, heart disease, lower urinary tract symptoms, heavy smoking, and depression and increased by 10% per year of age. It was inversely associated with education, physical activity, and alcohol drinking. CONCLUSIONS: ED is an international problem, the prevalence and severity of which increases with age. Despite national variations in prevalence, uniform associations were found between ED and medical conditions and lifestyle habits.

OBJECTIVE: To estimate the iatrogenic costs of nonsteroidal antiinflammatory drug (NSAID) treatment from the perspective of the Italian National Health Service. METHODS: We conducted a retrospective cohort study using the primary and secondary care claims data registered in the regional health service database in the Friuli-Venezia Giulia (Italy). The study cohort comprised all persons(265,114) who received at least one prescription for any NSAID between August 1996 and July 1998. The outcomes of interest were the costs of medical interventions for upper gastrointestinal disorders following NSAID treatment (i.e., prescriptions for gastroprotective drugs, hospitalizations, and outpatient diagnostic procedures). RESULTS: The study population received a total of 660,311 NSAID prescriptions for a cost of 6,587,533 Euros (0.53 euro per treatment day). The cost of medical interventions for gastrointestinal events added 58% to the cost of NSAID therapy (0.31 euro per NSAID treatment day, up to 64% directly attributable to NSAID use). The iatrogenic costs were generated by 12.4% of the patients, 77% of whom had a positive history of gastrointestinal disorders and 82% of whom were older than 50 years. Co-prescriptions for gastroprotective drugs accounted for 78.6% of the overall iatrogenic costs. The iatrogenic costs did not differ between cyclooxygenase (COX) nonselective and COX-2 preferential drugs within strata of age and prior history of gastrointestinal disorders, but were significantly higher for the parenteral NSAIDs than the oral or rectal formulations. CONCLUSIONS: In Italy, the iatrogenic costs of NSAID therapy add 58% to the cost of NSAID treatment; most of the cost is generated by co-prescriptions of gastroprotective drugs to elderly NSAID users or patients with a history of gastrointestinal disorders.
