Public awareness and views on unlicensed use of medicines in children.

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT center dot There is increasing concern about the use of those medicines in children which have not been fully studied and licensed for childhood use. Such use is not uncommon, due in large part to a lack of availability of fully licensed products and formulations that are suitable for children. center dot There is little published information on the views of the public on this important area of paediatric care. WHAT THIS STUDY ADDS center dot A survey of 1000 members of the public in Northern Ireland indicated that such use of medicines in children is not well known. center dot However, when informed about this practice, the majority believed that it would compromise safety and increase the likelihood of adverse effects. They also believed that parents/guardians should be told if their child was prescribed a medicine that had not been fully tested in children. center dot Participants in the survey indicated that they would be reluctant to involve their child in a clinical trial to help with the licensing process unless the child was suffering from a life-threatening illness. To explore awareness and views of the general public on unlicensed use of medicines in children and on the participation of children in clinical trials. Members of the public completed a questionnaire survey administered by face-to-face interview in public areas in N. Ireland. The main outcome measures were the views on unlicensed use of medicines in children and on clinical trials in children. One thousand participants (59.2% female) took part; 610 were parents. Most participants (86%) had no previous knowledge about unlicensed use of medicines in children. Being a parent did not influence this nor did being a parent of a child who suffered from a health problem (P > 0.05). Most participants (92%) felt that parents should be told about unlicensed use of medicines, with the doctor most frequently selected as the person who should inform parents. At the outset, only 1.8% of participants felt that the use of medicines in children was unsafe. However, having been informed about unlicensed use of medicines, this proportion increased dramatically (62.4%; P <0.001). Views on whether participants would enter a child of their own into a clinical trial varied according to the health status of the child (P <0.05) i.e. a child in good health (3.9%) vs a child with a life-threatening condition (41.9%). There is limited public knowledge of unlicensed use of medicines in children and a general reluctance to involve children in clinical trials unless the child to be involved has a life-threatening condition.

High bax expression is a good prognostic indicator in acute myeloid leukaemia

Most cytotoxic drugs kill cells by instigating the process of apoptosis and it has been suggested that apoptotic markers may provide an indication of tumour chemosensitivity. The aim of this study was to determine if such a relationship exists in acute myeloid leukaemia (AML). The levels of spontaneous apoptosis, bcl-2 and bax were evaluated in 56 newly diagnosed AML patients to determine if they correlated with a response to cytotoxic therapy. Spontaneous apoptosis was lower, but bcl-2, bax and the bcl-2/bax ratio were higher in AML compared with normal individuals. AML patients with high bax expression at diagnosis had significantly better prognosis for disease-free survival, event-free survival and overall survival (P = 0.016). In the standard risk group, high bax expression was in keeping with significantly improved survival. Multivariate analysis revealed bax to be an independent predictor of survival. There was a significant reduction in bcl-2 and bax expression when AML patients entered complete remission and also in relapsed AML patients who entered a second remission. This study suggests that bax is a useful prognostic indicator in AML and may assist with therapeutic decision-making for patients in the standard risk category.

Dogs in the paradise: The influence of the cynical philosophy in the construction of the myth of the good savage

This paper studies the influence of cynic philosophy in the construction of the myth of the good savage. In the first part it studies the importance of cynicism in the XVI century and how the cynic influence of Erasmus, More and Montaigne was fundamental to the way that Europe approached the American indigenous. In the second part it studies the cynic motives that could have influenced in the construction of the myth of the good savage.
