Viral RNAs (either derived from DNA viruses and genomic/mRNAs of RNA viruses) produced and replicated in eukaryotic cells are exposed to the activity of host cell RNA modification machinery. Moreover, some complex viruses encode their own RNA modification enzymes, generally cap-related m 7 G-and 2'-O-methyltransferases whose expression allows specific modification of viral transcripts and modulation of viral RNA recognition by host restriction systems. Here we review current achievements in the detection of viral RNA modifications by liquid chromatography coupled to mass spectrometry (LC-MS) and deep sequencing-based approaches. The presence, origin and characterized functions of RNA modifications in viral RNAs are discussed.

Ovarian cancer is the fifth most common cancer in women in France with 4714 new cases in 2017. More than 70% of patients whose disease is initially locally advanced will present locoregional or distant recurrence. Therapeutic options in this situation are not consensual. They are based on chemotherapy possibly associated with an iterative cytoreductive surgery when it is bearable by the patient. The place of radiotherapy in the management of the disease is hidden in the vast majority of national or international standards. We conducted a general review of the literature to clarify the role of irradiation in the global management of ovarian cancers, particularly in recurrence., (Copyright © 2020 Société française de radiothérapie oncologique (SFRO).

As more is learned about the importance of the intestinal microbiome to human health there is increasing interest in the potential benefits of probiotics. Probiotics are live micro-organisms which, when consumed in adequate amounts, confer a health effect on the host by altering its microflora. Probiotics have been administered both prophylactically and therapeutically for various conditions. This statement defines the development and role of intestinal microflora, and examines the evidence supporting the use of different probiotics to treat common paediatric conditions, such as diarrhea, atopy, functional intestinal disorders and necrotizing enterocolitis.

The majority of children between one and five years of age who are brought in by their parents for refusing to eat are healthy and have an appetite that is appropriate for their age and growth rate. Unrealistic parental expectations may result in unnecessary concern, and inappropriate threats or punishments may aggravate a child's refusal to eat. A detailed history and general physical examination are necessary to rule out acute and chronic illnesses. A food diary and assessment of parental expectations about eating behaviour should be completed. Where the child's 'refusal' to eat is found to be related to unrealistic expectations, parents should be reassured and counselled about the normal growth and development of children at this age.

Growth monitoring is an essential part of paediatric health care, from birth through adolescence. Growth and nutritional problems often occur between 18 months and three years of age. Health care professionals involved in the care of children need to follow growth closely in this period, be able to evaluate a toddler whose growth seems to be faltering, and know when and how to intervene.

Therapeutic patient education (TPE) has been standard practice in France for roughly 20 years. However, TPE has only recently been officially recognized and has rarely been assessed. The objective of this study was to assess the impact of TPE on passive smoking exposure and asthma outcomes in young patients referred to a hospital school for children with asthma. A prospective cohort study was conducted to determine the socio-economic status, environmental exposure (including parental tobacco consumption) and medical history of children starting out on a TPE course. The study measured quality of life and urinary cotinine. Asthma control was also assessed. Out of a total of 54 children (median age 8.6 years), 35 and 26 children attended three or at least four TPE sessions, respectively. Uncontrolled asthma and a history of hospitalization for exacerbation of asthma were frequent (43% and 61%, respectively). In utero passive smoke exposure was more frequent in the hospitalization group (p = 0.07). Urinary cotinine levels were similar in children exposed and not exposed to tobacco smoke (259 vs 141 nMol.L-1, p = 0.15), but only decreased in the group of exposed children. In 34 children, quality of life improved significantly between the first and the third or fourth sessions (n = 23, median increase 1.06, p = 0.1), while asthma control improved in 64% of the patients (n = 33, p = 0.01) and emergency attendances decreased (n = 34, p = 0.001). The positive effects of TPE on asthma control and quality of life were quickly visible but did not prevent children from withdrawing from the program. Urinary cotinine was not useful for detecting exposure to tobacco smoke, but may be useful as an indicator of exposure to tobacco smoke. The results indicate an improvement in quality of life and asthma control as TPE proceeded.

Despite the stabilisation of infant tuberculosis, the BCG vaccine remains strongly recommended for people at risk and regions with a high prevalence. The work of the early childhood worker in maternal and child protection centres (PMI) is crucial from the very first meeting, in order to inform and raise the awareness of families about the importance of early vaccination.

Purpose: Patients with permanent cardiac pacemakers occasionally require radiotherapy. Therapeutic irradiation may cause pacemakers to malfunction due to the effects of ionizing radiation or electromagnetic interference. We studied the breast cancer patients who needed breast and/or chest wall and lymph node irradiation to assess the feasibility and tolerance in this population of patients., Patients and Methods: From November 2008 to December 2009, more than 900 patients received radiotherapy for their breast cancer in our department using megavoltage linear accelerator (X 4-6 MV and electrons). Among them, seven patients were with permanent pacemaker. All patients have been treated to the breast and chest wall and/or lymph nodes. Total dose to breast and/or chest wall was 50 Gy/25 fractions and 46 Gy/23 fractions to lymph nodes. Patients who underwent conserving surgery followed by breast irradiation were boosted when indicated to tumour bed with 16 Gy/8 fractions. All patients were monitored everyday in presence of radiation oncologist to follow the function of their pacemaker. All pacemakers were controlled before and after radiotherapy by the patients' cardiologist., Results: Seven patients were referred in our department for postoperative breast cancer radiotherapy. Among them, only one patient was declined for radiotherapy and underwent mastectomy without radiotherapy. In four cases the pacemaker was repositioned before the beginning of radiotherapy. Six patients, aged between 48 and 84 years underwent irradiation for their breast cancer. Four patients were treated with conserving surgery followed by breast radiotherapy and two with mastectomy followed by chest wall and internal mammary chain, supra- and infra-clavicular lymph node irradiation. The dose to the pacemaker generator was kept below 2 Gy. There was no pacemaker dysfunction observed during the radiotherapy., Conclusion: The multidisciplinary work with position change of the pacemaker before radiotherapy and everyday monitoring permitted the safe treatment of our patients. Updated guidelines are definitely needed with more details about acceptable doses at the different parts of the pacemaker., (Copyright © 2011 Société française de radiothérapie oncologique (SFRO).

Purpose: We retrospectively assessed the use of trastuzumab concurrently with whole-brain radiotherapy (WBRT) for brain metastases., Patients and Methods: From April 2001 to April 2007, 31 patients with brain metastases from HER2-positive breast cancer were referred for WBRT with concurrent trastuzumab. In most cases, concurrent WBRT delivered 30 Gy in 10 daily fractions. In six patients, other fractionations were chosen because of either poor performance status or patients’ convenience., Results: At time of brain progression, median age was 55 years (range: 38 to 73 years) and all patients had a performance status of 0 to 2. Median time to brain progression was 10.5 months. Following WBRT, radiological responses were observed in 23 patients (74.2%), including six patients (19.4%) with complete radiological responses and 17 patients (54.8%) with partial radiological response. Clinical responses were observed in 27 patients (87.1%). Median survival from the start of WBRT was 18 months (range: two to 65 months). No grade 2 or more acute toxicity was observed., Conclusion: Our results suggest that trastuzumab concurrently with WBRT may have a potential clinical impact with low toxicity. Although promising, these preliminary data warrant further validation of trastuzumab as radio sensitizer for WBRT in brain metastases from breast cancer in the setting of a clinical trial. Larger prospective studies are needed to confirm these results.

The radiation dose received by the eye depends on the pathology, tumour location (ocular globe, orbit, neighboring structures) and the radiation technique. The major complication is the complete loss of vision, which is often multifactorial. This article, based on a literature review, describes the radiation effects and the tolerance doses for all eye structures: cornea, lens, retina, optic nerves, orbit and ocular adnexa., (Copyright (c) 2010 Société française de radiothérapie oncologique (SFRO).

Hydrogenation of fat products is used in the food industry to extend their shelf life. Trans fats are the result of partial hydrogenation of unsaturated fat. Trans fats increase low-density lipoprotein cholesterol and decrease high-density lipoprotein cholesterol, thus increasing the risk of cardiovascular disease. Canadians have one of the highest dietary intake of trans fat in the world. Health Canada has made recommendations to decrease the trans fat intake of Canadians. Physicians should be able to provide their patients with information on trans fats and their deleterious effects on health.

Purpose: Although a recent increase in number of young radiation oncologists in training has been observed during the past decade, the general demographic evolution of radiation oncologists covers partially future needs., Material and Method: During the seven past national annual courses, which were organised and supported by the Société française des jeunes radiothérapeutes oncologues (SFJRO), the Société française de radiothérapie oncologique (SFRO), the Collège national des enseignants de cancérologie (CNEC) and the Institut national du cancer (Inca), different types of surveys were realized in order to analyse demography, quality of training and motivations of French residents in radiation oncology. The latest results were collected during the last national course, which took place in March 2008. Seventy-five young French radiation oncologists ("internes des hopitaux" or residents) out of 110 participants who attended the national course and 75 questionnaires were analysed., Results: Since 2002, the total number of residents increased regularly (50, 75, 103 and 109 residents respectively in 2000, 2005, 2007 and 2008). Men and women are presently 48.5% and 51.5% respectively. Qualitative analysis of practical and theoretical training was performed using a visual analogical scale from zero to 10. Scores of 56 and 61 were respectively observed. Other descriptions of local training in the different universities (clinical skills, clinical cases analysis, bibliography session...) are described. Finally, analysis of the motivations for choosing the radiation oncology speciality demonstrates common interests in both medical practice and technical aspects in oncology. Innovation, technology, imaging and research are also widely mentioned. Sixteen residents will finish their training by the end of 2008, 42 are expected in 2009 and 27 in 2010. Almost all residents believe that a postgraduate position is necessary to complete their training as assistant professor ("chefs de clinique-assistants des hôpitaux") in a university hospital or a cancer centre. Unfortunately, only 36 assistant professor positions are available in France, representing half of the need. Only 21 residents out of 104 already have a position as assistant professor. The availability of such a position remains undetermined for the rest of them., Conclusions: Despite the recent increase in the number of residents in radiation oncology in France, the need to create new assistant professor positions is crucial to assure quality of training for this both medical and technical speciality. Since 2002, the establishment of SFJRO has facilitated national links among residents, between residents and professors (CNEC), and between the French society (SFRO) and the European society (ESTRO).

For the last three years, our oncology ICU (intensive care unit) has been opened to visiting children between 0 and 18 years. Our objective was to attempt to decrease the psychological burden in critically ill cancer patients and their children. We report here the evaluation of this new policy. Encouraged by the child psychologists in our hospital, we first recorded the opinions of the nursing staff, patients and relatives about this innovative approach. As our preliminary findings were favourable, a liberalised greeting and education policy for visiting children was implemented. A dedicated procedure was followed in order to provide children with a better understanding of their parent's disease, to alleviate any traumatic experience the visit might cause and to create an environment where mutual confidence would reign. After 2 years, each visiting child, patient, accompanying parent and the nursing staff were directly questioned using a specifically designed questionnaire. The daily lives of the staff, children, families and patients themselves appeared to be dramatically improved, even in the most difficult medical situations. Based on these promising results, the new policy has definitively been adopted in our unit. We propose that children ought to be allowed to visit a parent in the ICU and that this policy warrants evaluation in other types of units.

Introduction: Asthma, the most frequent chronic disease in childhood, is often treated by a continuous preventive treatment associated to the treatment of attacks. This therapeutic scheme fits well with educative skills. The Robert Debré's asthma school has been created in December 1999. Two nurses specialized in child asthma education are working in the school, helped by the pediatric pulmonologists. Children 6-year-old or more, that are treated in the hospital for asthma may be sent to the asthma school for education. They receive individual or collective education for cognitive, psycho-affective and sensory-motor targets related to asthma., Aim of the Study: To evaluate the outcome of educative action in childhood asthma and to study hospitalizations costs., Subjects: children who received education for the first time in the year 2000 or 2001 and in whom exhaustive computerized data were available were eligible for the study., Methods: retrospective and comparative study one-year-before/one-year-after the first educational intervention, assessed by comparison of the numbers of scheduled medical consultations and hospitalizations (and their cost)., Results: Sixty-six children were studied. We registered a significant increase of scheduled medical consultations (177 vs. 223; P < 0.03), and a very significant decrease of hospitalizations for asthma attacks (32 vs. 11; P < 0.001) without influence of the number of educational interventions and with a 52% decrease in costs (84,788 vs. 40,073 euros; P < 0.03)., Conclusion: Asthmatic children education is a useful tool to improve medical follow-up and to decrease hospitalizations number. In a two-year survey, the decrease of cost in a group of 66 children is 44,715 euros.
