Toxicity at three years with and without irradiation of the internal mammary and medial supraclavicular lymph node chain in stage I to III breast cancer (EORTC trial 22922/10925).

INTRODUCTION: The EORTC 22922/10925 trial investigated the potential survival benefit and toxicity of elective irradiation of the internal mammary and medial supraclavicular (IM-MS) nodes Accrual completed in January 2004 and first results are expected in 2012. We present the toxicity reported until year 3 after treatment. PATIENTS AND METHODS: At each visit, toxicity was reported but severity was not graded routinely. Toxicity rates and performance status (PS) changes at three years were compared by chi(2) tests and logistic regression models in all the 3,866 of 4,004 patients eligible to the trial who received the allocated treatment. RESULTS: Only lung (fibrosis; dyspnoea; pneumonitis; any lung toxicities) (4.3% vs. 1.3%; p < 0.0001) but not cardiac toxicity (0.3% vs. 0.4%; p = 0.55) significantly increased with IM-MS treatment. No significant worsening of the PS was observed (p = 0.79), suggesting that treatment-related toxicity does not impair patient's daily activities. CONCLUSIONS: IM-MS irradiation seems well tolerated and does not significantly impair WHO PS at three years. A follow-up period of at least 10 years is needed to determine whether cardiac toxicity is increased after radiotherapy.

Reverse transcription quantitative real-time polymerase chain reaction reference genes in the spared nerve injury model of neuropathic pain : validation and literature search

La douleur neuropathique est définie comme une douleur causée par une lésion du système nerveux somato-sensoriel. Elle se caractérise par des douleurs exagérées, spontanées, ou déclenchées par des stimuli normalement non douloureux (allodynie) ou douloureux (hyperalgésie). Bien qu'elle concerne 7% de la population, ses mécanismes biologiques ne sont pas encore élucidés. L'étude des variations d'expressions géniques dans les tissus-clés des voies sensorielles (notamment le ganglion spinal et la corne dorsale de la moelle épinière) à différents moments après une lésion nerveuse périphérique permettrait de mettre en évidence de nouvelles cibles thérapeutiques. Elles se détectent de manière sensible par reverse transcription quantitative real-time polymerase chain reaction (RT- qPCR). Pour garantir des résultats fiables, des guidelines ont récemment recommandé la validation des gènes de référence utilisés pour la normalisation des données ("Minimum information for publication of quantitative real-time PCR experiments", Bustin et al 2009). Après recherche dans la littérature des gènes de référence fréquemment utilisés dans notre modèle de douleur neuropathique périphérique SNI (spared nerve injury) et dans le tissu nerveux en général, nous avons établi une liste de potentiels bons candidats: Actin beta (Actb), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), ribosomal proteins 18S (18S), L13a (RPL13a) et L29 (RPL29), hypoxanthine phosphoribosyltransferase 1 (HPRT1) et hydroxymethyl-bilane synthase (HMBS). Nous avons évalué la stabilité d'expression de ces gènes dans le ganglion spinal et dans la corne dorsale à différents moments après la lésion nerveuse (SNI) en calculant des coefficients de variation et utilisant l'algorithme geNorm qui compare les niveaux d'expression entre les différents candidats et détermine la paire de gènes restante la plus stable. Il a aussi été possible de classer les gènes selon leur stabilité et d'identifier le nombre de gènes nécessaires pour une normalisation la plus précise. Les gènes les plus cités comme référence dans le modèle SNI ont été GAPDH, HMBS, Actb, HPRT1 et 18S. Seuls HPRT1 and 18S ont été précédemment validés dans des arrays de RT-qPCR. Dans notre étude, tous les gènes testés dans le ganglion spinal et dans la corne dorsale satisfont au critère de stabilité exprimé par une M-value inférieure à 1. Par contre avec un coefficient de variation (CV) supérieur à 50% dans le ganglion spinal, 18S ne peut être retenu. La paire de gènes la plus stable dans le ganglion spinal est HPRT1 et Actb et dans la corne dorsale il s'agit de RPL29 et RPL13a. L'utilisation de 2 gènes de référence stables suffit pour une normalisation fiable. Nous avons donc classé et validé Actb, RPL29, RPL13a, HMBS, GAPDH, HPRT1 et 18S comme gènes de référence utilisables dans la corne dorsale pour le modèle SNI chez le rat. Dans le ganglion spinal 18S n'a pas rempli nos critères. Nous avons aussi déterminé que la combinaison de deux gènes de référence stables suffit pour une normalisation précise. Les variations d'expression génique de potentiels gènes d'intérêts dans des conditions expérimentales identiques (SNI, tissu et timepoints post SNI) vont pouvoir se mesurer sur la base d'une normalisation fiable. Non seulement il sera possible d'identifier des régulations potentiellement importantes dans la genèse de la douleur neuropathique mais aussi d'observer les différents phénotypes évoluant au cours du temps après lésion nerveuse.

Dengue virus detection by using reverse transcription-polymerase chain reaction in saliva and progeny of experimentally infected Aedes albopictus from Brazil

Oral susceptibility and vertical transmission of dengue virus type 2 (DENV-2) in an Aedes albopictus sample from Rio de Janeiro was estimated. The infection (36.7%) and transmission (83.3%) rates for Ae. albopictus were higher than those of an Ae. aegypti colony used as control, 32.8 and 60%, respectively. Fourth instar larvae and females descendants of 48.5 and 39.1% of experimentally infected Ae. albopictus showed to harbor the virus. The oral susceptibility and the high capacity to assure vertical transmission exhibited by Ae. albopictus from Brazil reinforce that this species may play a role in the maintenance of the virus in nature and be a threat for dengue control in the country.

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.

Implementing A vision for change: moving towards a modern, quality and responsive mental health service. Carlow / Kilkenny / South Tipperary.

The key element of the HSE South’s Programme is to enhance and develop community mental health services in Carlow, Kilkenny and South Tipperary, to enable the service user to remain in the community to the greatest extent possible. HSE South has prioritised the implementation of the change programme and has allocated more than €20m capital funding and over €1.75m revenue funding to support this comprehensive development programme. Speaking at the briefings Mr. Pat Healy, Regional Director of Operations, HSE South said, “When this plan is delivered, clients will have access to the highest standards of services in all three counties, which should significantly improve these clients’ treatment programmes and quality of life. The National Service Users Executive are supporting the change programme, which is of immense importance to HSE South. The programme heralds the enhancement and development of community mental health services, the closure of old long stay institutions, the separation of North and South Tipperary acute inpatient mental health services and development of appropriate acute inpatient services, for the extended catchment area, in line with the national strategy for mental health “A Vision for Change”. The programme also acts on recommendations of the Mental Health Commission.”This resource was contributed by The National Documentation Centre on Drug Use.

Cognitive behavioural skills for practice a model for delivery in the Irish mental health service.

This publication outlines a model of delivery for introductory level Cognitive Behavioural Therapy (CBT) training in the Mental Health Service, HSE South (Carlow, Kilkenny, South Tipperary, Waterford, Wexford). This model has proved useful in guiding the development of four introductory programmes during 2009 and 2010. As a result of this experience, we have amended and updated our programme delivery strategies. We see this process as organic and ever changing, thus these reflections are a snap shot of our current thinking which we have no doubt will evolve as we proceed with future programmes. This booklet will act as a guide for our upcoming programmes in 2010 and 2011 and we believe it may also offer guidance to others who will be involved in the delivery of CBT training within the Irish Mental Health Service.This resource was contributed by The National Documentation Centre on Drug Use.

Obesity in an ageing society implications for health, physical function and health service utilisation.

Key Findings • Based on body mass index (BMI) measurements, 36% of Irish over 50s are obese and a further 43% are overweight. • Based on waist circumference measurements, 52% of Irish over 50s are ‘centrally obese’, i.e., with a ‘substantially increased’ waist circumference, while a further 25% have an ‘increased’ waist circumference. • Using BMI as an indicator of obesity, a higher proportion of men (38%) are obese than women (33%); however, using waist circumference as an indicator of obesity, a higher proportion of women (56%) have a ‘substantially increased’ waist circumference than men (48%). • The prevalence of obesity in Irish men over 50 is comparable with US men over 50 (while English rates are much lower).     .This resource was contributed by The National Documentation Centre on Drug Use.

The Role and Future Development of the Meals-on-Wheels Service for Older People in Ireland

This report provides, for the first time, a snapshot of the meals-on-wheels service in Ireland and gives a unique insight into client and provider perceptions of the service. The research findings underline the dual importance of the service for clients, who noted that it is a vital source of both nutritious meals and social contact and connectivity to the wider community. From a supply side perspective, the research findings point to the wide organisational diversity that exists within the service and the critical role that volunteers play, as well as highlighting difficulties that many services currently experience.

Detection of Leishmania braziliensis in human paraffin-embedded tissues from Tucumán, Argentina by polymerase chain reaction

American cutaneous leishmaniasis (ACL) is an endemic disease in Northern Argentina. We applied the polymerase chain reaction (PCR) followed by a hybridization labelled probe to 21 paraffin embedded human skin biopsies, already analyzed histologically, from leishmaniasis endemic areas in the province of Tucumán, Argentina. We used primers previously designed to detect a Leishmania-specific 120-base-pair fragment of kinetoplast DNA minicircle, other two primer pairs that amplify kDNA minicircles belonging to the L. braziliensis and L. mexicana complexes respectively, and specific oligonucleotide primers to detect L. (V.) braziliensis which amplify the sequence of the ribosomal protein L-14 of this species. The PCR-hybridization showed a sensitivity of 90.5% when compared to the histopathology test which was 61.9%. Five of the total samples analyzed were positive for the L. braziliensis complex whilst none was positive for the L. mexicana complex. The specific primers for L. (V.) braziliensis detected the parasite in four samples. These results are consistent with those reported for close endemic areas and demonstrate that the causative agent of human leishmaniasis in the analyzed cases was L. (V.) braziliensis. PCR should be used as a diagnostic tool for tegumentary leishmaniasis, especially in the mucosal form, and as a valuable technique for the identification of the Leishmania species that causes the disease in certain areas.

Diagnosis of Brazilian vesiculoviruses by reverse transcription-polymerase chain reaction

We describe a reverse transcription-polymerase chain reaction (RT-PCR) and a nested-PCR for diagnosis of Piry, Carajás, Cocal, and Alagoas vesiculoviruses from Brazil. The RNA extracts of viral and clinical samples were submitted to a RT-PCR using Vesiculovirus G primers that amplify part of the glycoprotein gene. The RT-PCR produced amplicons of expected size, 290 base pair, for the four studied viruses. The RT-PCR showed a high sensitivity being 151.3 times (2.18 log) more sensitive for the detection of Piry virus than the classical procedure for virus detection in tissue culture based on the viral cytophatic effect. Amplicons had nucleotides sequenced and were aligned in order to select internal primers for a nested-PCR to confirm the origin of Piry, Carajás, Cocal, and Alagoas Vesiculovirus. Ten blood and tarsal pad epithelial samples of infected Guinea-pigs had Vesiculovirus genome amplified by RT-nested-PCR.

Detection of Brazilian spotted fever infection by polymerase chain reaction in a patient from the state of São Paulo

Brazilian spotted fever (BSF) cases have been increasing in the state of São Paulo but no genomic information about local rickettsia isolated from humans has been well documented. We recovered spotted-fever group rickettsiae from a sample of patient blood cultured in Vero cells using the shell vial technique. Rickettsial DNA fragments (gltA, ompA, and, ompB genes) were detected, and analysis of the ompB gene base sequences showed identity with the Rickettsia rickettsii ompB sequence available in the GenBank.

Identification of Anopheles (Nyssorhynchus) albitarsis complex species (Diptera: Culicidae) using rDNA internal transcribed spacer 2-based polymerase chain reaction primes

Anopheles (Nyssorhynchus) marajoara is a proven primary vector of malaria parasites in Northeast Brazil, and An. deaneorum is a suspected vector in Western Brazil. Both are members of the morphologically similar Albitarsis Complex, which also includes An. albitarsis and an undescribed species, An. albitarsis "B". These four species were recognized and can be identified using random amplified polymorphic DNA (RAPD) markers, but various other methodologies also point to multiple species under the name An. albitarsis. We describe here a technique for identification of these species employing polymerase chain reaction (PCR) primers based on ribosomal DNA internal transcribed spacer 2 (rDNA ITS2) sequence. Since this method is based on known sequence it is simpler than the sometimes problematical RAPD-PCR. Primers were tested on samples previously identified using RAPD markers with complete correlation.

Profile of CAMHS service users in the East Midlands

This section uses the Children and Adolescent Mental Health Services mapping exercise set up in 2002, currently data is being collected for the 2005 exercise. This mapping is carried out on an annual basis collecting data on the specialist CAMH tier 2-4 services. Tier 1 is cover by professionals such as GPs and school nurses whereas tier 4 are highly specialised tertiary level services, tiers 2 and 3 cover the spectrum in between. The purpose of the mapping is to contribute towards the improvement of mental health services for children and adolescents by informing and supporting the implementation of the Children's Nation Service Framework.

Tackling Child Obesity - First Steps

Obesity is a complex public health issue that is a growing threat to children۪s health, as well as a current and future drain on National Health Service (NHS) resources. The Wanless Report stated that public health the promotion of good health and the prevention of disease should be central to the work of the NHS.2 Obesity already costs the NHS directly around 1 billion a year and the UK economy a further 2.3 to 2.6 billion in indirect costs. If this present trend continues, by 2010 the annual cost to the economy could be 3.6 billion a year. This joint report from the Audit Commission, Healthcare Commission and the National Audit Office aims to identify how the barriers to creating a successful delivery chain can be addressed and makes recommendations about how the delivery chain might be strengthened and made more efficient as part of the need for the Departments to contribute to the Government۪s wider efficiency programme.
