Missed appointments in an adolescent outpatient clinic : descriptive analyses of consultations over eight years ; et, Missed appointments in an outpatient clinic for adolescents, an approache to predict the risk of missing

Rapport de synthèse: Les rendez-vous manqués représentent un problème important, tant du point de vue de la santé des patients que du point de vue économique. Pourtant peu d'études se sont penchées sur le sujet, particulièrement dans une population d'adolescents. Les buts de cette étude étaient de caractériser les adolescents qui sont à risque de manquer ou d'annuler leurs rendez-vous dans une clinique ambulatoire de santé pour adolescents, de comparer les taux des rendez-vous manqués et annulés entre les différents intervenants et d'estimer l'efficacité d'une politique de taxation des rendez-vous manqués non excusés. Finalement, un modèle multi-niveau markovien a été utilisé afin de prédire le risque de manquer un rendez-vous. Ce modèle tient compte du passé de l'adolescent en matière de rendez-vous manqués et d'autres covariables et permet de grouper les individus ayant un comportement semblable. On peut ensuite prédire pour chaque groupe le risque de manquer ou annuler et les covariables influençant significativement ce risque. Entre 1999 et 2006, 32816 rendez-vous fixés pour 3577 patients âgés de 12 à 20 ans ont été analysés. Le taux de rendez-vous manqués était de 11.8%, alors que 10.9% avaient été annulés. Soixante pour cent des patients n'ont pas manqué un seul de leur rendezvous et 14% en ont manqué plus de 25%. Nous avons pu mettre en évidence plusieurs variables associées de manière statistiquement significative avec les taux de rendez-vous manqués et d'annulations (genre, âge, heure, jour de la semaine, intervenant thérapeutique). Le comportement des filles peut être catégorisé en 2 groupes. Le premier groupe inclut les diagnostiques psychiatriques et de trouble du comportement alimentaire, le risque de manquer dans ce groupe étant faible et associé au fait d'avoir précédemment manqué un rendez-vous et au délai du rendez-vous. Les autres diagnostiques chez les filles sont associés à un second groupe qui montre un risque plus élevé de manquer un rendez-vous et qui est associé à l'intervenant, au fait d'avoir précédemment manqué ou annulé le dernier rendez-vous et au délai du rendez-vous. Les garçons ont tous globalement un comportement similaire concernant les rendez-vous manqués. Le diagnostic au sein de ce groupe influence le risque de manquer, tout comme le fait d'avoir précédemment manqué ou annulé un rendez-vous, le délai du rendez-vous et l'âge du patient. L'introduction de la politique de taxation des rendez-vous non excusés n'a pas montré de différence significative des tàux de rendez-vous manqués, cependant cette mesure a permis une augmentation du taux d'annulations. En conclusion, les taux de présence des adolescents à leurs rendez-vous sont dépendants de facteurs divers. Et, même si les adolescents sont une population à risque concernant les rendez-vous manqués, la majorité d'entre eux ne manquent aucun de leurs rendez-vous, ceci étant vrai pour les deux sexes. Etudier les rendez-vous manqués et les adolescents qui sont à risque de rater leur rendez-vous est un pas nécessaire vers le contrôle de ce phénomène. Par ailleurs, les moyens de contrôle concernant les rendez-vous manqués devraient cibler les patients ayant déjà manqué un rendez-vous. La taxation des rendez-vous manqués permet d'augmenter les rendez-vous annulés, ce qui a l'avantage de permettre de fixer un nouveau rendez-vous et, de ce fait, d'améliorer la continuité des soins.

Gender differences in HIV progression to AIDS and death in industrialized countries: slower disease progression following HIV seroconversion in women.

To evaluate sex differences in human immunodeficiency virus (HIV) disease progression before (pre-1997) and after (1997-2006) introduction of highly active antiretroviral therapy, the authors used data from a collaboration of 23 HIV seroconverter cohort studies from Europe, Australia, and Canada restricted to the 6,923 seroconverters infected through injecting drug use and sex between men and women. Within a competing risk framework, they used Cox proportional hazards models allowing for late entry to evaluate sex differences in time from HIV seroconversion to death, to acquired immunodeficiency syndrome (AIDS), and to each first AIDS-defining disease and death without AIDS. While no significant sex differences were found before 1997, from 1997 onward, women had a lower risk of AIDS (adjusted cumulative relative risk (aCRR) = 0.76, 95% confidence interval (CI): 0.63, 0.90) and death (adjusted hazard ratio = 0.68, 95% CI: 0.56, 0.82) than men did. Compared with men, women also had lower risks of AIDS dementia complex (aCRR = 0.23, 95% CI: 0.07, 0.74), tuberculosis (aCRR = 0.60, 95% CI: 0.39, 0.92), Kaposi's sarcoma (aCRR = 0.27, 95% CI: 0.07, 0.99), lymphomas (aCRR = 0.47, 95% CI: 0.23, 0.96), and death without AIDS (aCRR = 0.74, 95% CI: 0.56, 0.98). Sex differences in HIV disease progression have become larger and statistically significant in the era of highly active antiretroviral therapy, supporting a stronger impact of health interventions among women.

Missed appointments in an adolescent outpatient clinic: descriptive analyses of consultations over 8 years.

Missed appointments represent an important medical and economical issue. Few studies on the subject are reported in the literature, particularly regarding adolescents. Our aim was to characterize missed and cancelled appointments in a multidisciplinary outpatient clinic for adolescents, to assess the effectiveness of a policy aimed at reducing missed appointments by introducing payment for those missed appointments not cancelled in advance, and to compare the rates between staff and resident physicians. A total of 32,816 consultations (representing 35 patients aged 12-20 years, 82.4% females) between 1999 and 200 were analysed. The missed appointment rate was 11.8% whilst another 10.9% were cancellations. Females cancelled more than males (11.3% vs. 8.4%, AOR 1.31, 99% CI 1.08-1.59), but there was no difference for missed appointments (11.6% vs. 12.3%, AOR 0.88, 99% CI 0.61-1.08). April and June to October (vacation months) were associated with more missed appointments. Globally mornings had higher rates of missed appointments than afternoons (13.6% vs. 11.2%, AOR 1.25, 99% CI 1.11-1.40). There was a slight difference in missed appointment rates between staff physicians and residents (10.4%; 11.8%, AOR 1.20, 99% CI 1.08-1.33). Missed appointment rates before and after the new policy on missed appointments were similar (1999-2003: 11.9%; 2004-2006: 11.6%, AOR 0.96, 99% CI 0.83-1.10). Conversely, cancellation rates increased from 8.4% (1999-2003) to 14.5% (2004-2006) (AOR 1.83, 99% CI 1.63-2.05). Attendance rates among adolescents show variations depending on vacation and school hours. Being attentive to these factors could help prevent missed appointments. Although having to pay for missed appointments does not increase attendance, it increases cancellations with the advantage that the appointment can be rescheduled.

In vitro susceptibility characteristics of Cryptococcus neoformans varieties from AIDS patients in Goiânia, Brazil

Sixty clinical isolates of Cryptococcus neoformans from AIDS from Goiânia, state of Goiás, Brazil, were characterized according to varieties, serotypes and tested for antifungal susceptibility. To differentiate the two varieties was used L-canavanine-glycine-bromothymol blue medium and to separate the serotypes was used slide agglutination test with Crypto Check Iatron. The Minimal Inhibitory Concentration (MIC) of fluconazole, itraconazole, and amphotericin B were determined by the National Committee for Clinical Laboratory Standards macrodilution method. Our results identified 56 isolates as C. neoformans var. neoformans serotype A and 4 isolates as C. neoformans var. gattii serotype B. MIC values for C. neoformans var. gattii were higher than C. neoformans var. neoformans. We verified that none isolate was resistant to itraconazole and to amphotericin B, but one C. neoformans var. neoformans and three C. neoformans var. gattii isolates were resistant to fluconazole. The presence of C. neoformans var. gattii fluconazole resistant indicates the importance of determining not only the variety of C. neoformans infecting the patients but also measuring the MIC of the isolate in order to properly orient treatment.

Premature epiphyseal closure in an adolescent treated by retinoids for acne: an unusual cause of anterior knee pain.

Retinoids are effective and widely prescribed in the treatment of severe acne. However their use can be associated with numerous side effects. Some rare cases of premature epiphyseal closure were reported. We present the case of a sixteen-year-old soccer player referred for progressive anterior pain in both knees, evoking a patellar problem. Careful pharmacological questioning revealed use of isotretinoin for several months. MRI findings showed an irregularity of the growth plate and an important metaphyso-epiphyseal oedema, more noticeable in the left knee. Retinoid-induced premature epiphyseal closure was diagnosed. The treatment was stopped, with a resolution of pain within two months. After recovery a persisting small sequelar thumbprint-like growth plate lesion was observed on the control MRI. Retinoids induce an invasion of the growth plate by osteoclasts and a decrease in proteoglycans synthesis. It seems that the knee is the most affected joint. This complication being rare, a radiological follow-up of the young patients treated by retinoids is not proposed.

Cellular immune responses and disease control in acute AIDS-associated Kaposi's sarcoma.

Kaposi's sarcoma-associated herpesvirus (KSHV) specific T cell responses and KSHV viremia were analyzed in seven HIV-infected patients with active Kaposi's sarcoma lesions who initiated highly active antiretroviral therapy, and were compared between patients with improved Kaposi's sarcoma and those with progressive Kaposi's sarcoma requiring further systemic chemotherapy. Patients with controlled Kaposi's sarcoma disease demonstrated undetectable Kaposi's sarcoma viremia together with KSHV-specific CD8 T cells secreting interferon-gamma and tumor necrosis factor-alpha, whereas progressors showed increasing viremia with weak or no T-cell responses. These data point toward a potential role of KSHV-specific immunity in the control of AIDS-associated Kaposi's sarcoma.

Young People and Food: Adolescent Dietary Beliefs and Understandings

This research provides fresh insight into the dichotomy between young people's knowledge of food safety and nutrition, and their behaviour.

Migraine, céphalées de l'enfant et de l'adolescent

La migraine de l'enfant est paradoxale à plus d'un titre : lors des crises, la douleur est sévère, les enfants sont souvent livides, « cadavériques », incapables de bouger, ils sont obligés de s'allonger dans la pénombre, vomissent parfois massivement, voient, sentent, entendent des « choses bizarres » - correspondant aux auras ; mais ils se réveillent en pleine forme après avoir dormi quelques heures... et tous les examens sont normaux. Alors que 5 à 10 % des enfants sont migraineux, le diagnostic n'est posé que pour une petite partie d'entre eux. La migraine est pourtant la première cause de céphalées intenses récurrentes chez l'enfant, la plupart des professionnels cherchant vainement une cause, et évoquant « les yeux, une gastro, les sinus ou bien une origine psy... ». Cet ouvrage a pour double objectif de présenter l'état de la science (épidémiologie, physiopathologie, génétique...) qui s'est largement enrichi ces dix dernières années et d'apporter aux professionnels des outils concrets pour identifier les céphalées et améliorer la prise en charge des enfants et des adolescents migraineux. Les céphalées de tension, les céphalées chroniques, les syndromes épisodiques associés à la migraine sont aussi détaillés. Illustré de nombreuses vignettes cliniques, cet ouvrage précise les critères diagnostiques, les pièges et les idées fausses ; il décrit comment rechercher les facteurs déclenchants et particulièrement ceux d'origine psychosociale, comment utiliser et combiner les traitements médicamenteux et non médicamenteux (notamment les approches psychothérapeutiques et psychocorporelles). Telle est l'ambition de ce livre, destiné à tous les professionnels confrontés à des enfants et des adolescents migraineux, mais également accessible en grande partie aux familles.

Improvement of the HIV/AIDS vaccine candidate NYVAC-C by deletion of the viral type I IFN inhibitor and/or acquisition of replication competence

Background: Recombinant viruses based on the attenuated vaccinia virus strain NYVAC are promising HIV vaccine candidates as phase I/II clinical trials have shown good safety and immunogenicity profiles. However, this NYVAC strain is non-replicating in most human cell lines and encodes viral inhibitors of the immune system. Methods: With the aim to increase the immune potency of the current NYVAC-C vector (expressing the codon optimized clade C HIV-1 genes encoding gp120 and Gag-Pol-Nef polyprotein), we have generated and characterized three NYVAC-C-based vectors by, 1) deletion of the viral type I IFN inhibitor gene (NYVAC-CdeltaB19R), 2) restoration of virus replication competence in human cells by re-inserting K1L and C7L host range genes (NYVAC-C-KC) and, 3) combination of both strategies (NYVACC- KC-deltaB19R). Results: Insertion of the KC fragment restored the replication competence of the viruses in human cells (HeLa cells and primary dermal fibroblasts and keratinocytes), increased the expression of HIV antigens by more than 3-fold compared to the non-replicating homologs, inhibited apoptosis induced by the parental NYVAC-C and retained attenuation in a newborn mouse model. In adult mice, replication-competent viruses showed a limited capacity to replicate in tissues surrounding the inoculation site (ovaries and lymph nodes). After infection of keratinocytes, PBMCs and dendritic cells these viruses induced differential modulation in specific host cell signal transduction pathways, triggering genes important in immune modulation. Conclusion: We have developed improved NYVAC-C-based vectors with enhanced HIV-1 antigen expression, with the ability to replicate in cultured human cells and partially in some tissues, with an induced expression of cellular genes relevant to immune system activation, and which trigger IFN-dependent and independent signalling pathways, while maintaining a safety phenotype. These new vectors are promising new HIV vaccine candidates. These studies were performed within the Poxvirus Tcell Vaccine Discovery Consortium (PTVDC) which is part of the CAVD program.

A Study of the Epidemiology of AIDS in Ireland and an Evaluation of an AIDS Education Programme in Second-level Schools

Second-level school students have been identified by the Minister for health as a priority group for education on AIDS. An education programme was accordingly initiated in 1988 in Community Care Area 1 in South county Dublin. This report evaluates this education intervention by means of pre- and post- intervention questionnaires. The questionnaire examined knowledge and attitudes of students relevant to AIDS. The results showed that the level of knowledge of students living in this area was high prior to intervention. The education programme succeeded in improving some aspects of knowledge and also influenced some attitudes of the students. A study of the epidemiology of Aids in Ireland reveals that the epidemic is at a relatively early stage with a consequent rapid doubling time of 9-10 months. In comparison with most developed countries Ireland has a high proportion of AIDS cases occurring among intravenous drug abusers and directly related to this a high number of HIV infected children. Examination of the literature reveals that behaviour change has occurred most noticeably among the homosexual/bisexual risk group. There is some evidence that the comprehensive programmes can achieve change in the behaviour of intravenous drug abusers. There are very few reports linking behaviour change among adolescents and young adults to education programmes. Much of the available literature relates to changes in knowledge and attitudes. International recommendations on the nature of the ideal health education intervention on AIDS are reviewed. The importance of a comprehensive health education programme which incorporates AIDS education and which commences early in youth is noted. The role of the community physician in relation to education programmes and other aspects of monitoring and management of the AIDS epidemic is discussed.This resource was contributed by The National Documentation Centre on Drug Use.

A Survey of Health Service Utilisation and Health Needs of a Population of Patient with HIV/ AIDS

This study described the demographic and medical characteristics of a population of patients with HIV/AIDS attending the department of Genito-Urinary Medicine (GUM) at a major Dublin hospital. The study population's utilisation of statutory and voluntary medical and social services at primary care level, satisfaction with services received and perceived need for services examined. The information obtained was used to make recommendations concerning the provision of care to patients with HIV/AIDS. The study was carried out between February and November 1994. Data was collected from a consecutive sample of eighty inpatients using n interviewer-administered questionnaire which contained both closed and open questions. The first forty patients interviewed were reviewed six months following the initial interview to document changes in physical condition and uptake of medical services over that time period. Data for the second part of the study was obtained by review of the patients' medical case notes and interview with the individual hospital medical social worker assigned to each patient. Over ninety percent of respondents were from the Greater Dublin Area. Almost three quarters were intravenous drug users (IVDUs), and the majority of these patients came from south inner city Dublin. The methodology was biased towards sampling patients with advanced disease and 73% had CDC Stage 4 disease. Twenty percent required some assistance with the activities of daily living when first interviewed. Most were reliant on informal carers. Social and physical dependency increased substantially over the six month period of the follow-up study of forty patients. Financial difficulties were identified as a particular area of need. Only ten percent of those interviewed were in current employment and over 80% were dependent on statutory payments. There is a need for greater co-ordination between the providers of services to patients HIV/AIDS and an improved system of data collection regarding patients' uptake of services and unmet needs is required to assist in future service planning.This resource was contributed by The National Documentation Centre on Drug Use.

Adult consequences of late adolescent alcohol consumption: a systematic review of cohort studies.

Alcohol is responsible for a significant portion of the global burden of disease. There is widespread concern reported in the media and other sources about drinking trends among young people, particularly heavy episodic or “binge” drinking. Prominent among policy responses, in the UK and elsewhere, have been attempts to manage antisocial behaviour related to intoxication in public spaces. Much less attention has been given to the longer term effects of excessive drinking in adolescence on later adult health and well-being. Some studies suggest that individuals “mature out” of late adolescent drinking behaviour, whilst others identify enduring effects on drinking and broader health and social outcomes in adulthood. If adolescent drinking does not cause later difficulties in adulthood then intervention approaches aimed at addressing the acute consequences of alcohol, such as unintentional injuries and anti-social behaviour, may be the most appropriate solution. If causal relationships do exist, however, this approach will not address the cumulative harms produced by alcohol, unless such intervention successfully modifies the long-term relationship with alcohol, which seems unlikely. To address this issue a systematic review of cohort studies was conducted, as this approach provides the strongest observational study design to evaluate evidence for causal inference.This resource was contributed by The National Documentation Centre on Drug Use.

HIV & AIDS education and prevention plan 2008-2012. Mid-term review.

In 2008 a 4-year plan for HIV and AIDS Education and Prevention in Ireland was published. The plan aimed to contribute to a reduction in new infections of HIV and AIDS through education and prevention measures. It also aimed to guide and inform the development of policy and services in the statutory and non-statutory sectors with responsibility in this regard. This report is produced as a response to a letter from the Secretariat of the National AIDS Strategy Committee (NASC). The letter requested “feedback from the Education and Prevention Sub-Committee on prevention activities currently in place and on progress to date on the Education and Prevention Action Plan (2008-2012).” In addition, action 2 under Action Area 5: Monitoring and evaluation states that “a mid-term review of the implementation of this action plan should be published”. We note from the HPSC data that there has been a slight decrease in the overall number of new HIV infections however; there has been a huge concern over the large increase in new diagnoses in men who have sex with men (MSM). Although we cannot provide the evidence for the reason for this increase, it is stipulated that there has been a huge increase in the education and prevention programmes targeted at MSM and the report will show the evidence of that increase (Action Area 3: Preventing new infections: population group MSM). There is a presumption that because of increased awareness, access and confidence of MSM and improved treatment that there are more MSM being tested and more diagnoses. This report presents an update on the progress of the implementation of the actions in the HIV and AIDS Education and Prevention Plan 2008-2012.This resource was contributed by The National Documentation Centre on Drug Use.
