Clinical features, diagnosis Non-ossifying bone fibromas are completely asymptom- atic. In very rare instances, the cortex may cave in, resulting in lesion-induced pain. Exceptionally, very large fibromas can cause the bone to swell up and lead to a palpable thickening.

Breathing-focused relaxation has the advantage of being brief and easy for patients to learn discount red viagra 200mg line. Other traditional relaxation techniques may require more instruction and practice time to be effective order red viagra 200 mg with visa. Progressive muscle relaxation (PMR) has been shown to be a useful technique for reducing physiological arousal and anxiety, and appears to be effective even in somewhat abbreviated form (Carlson & Hoyle, 1993). PMR, which can be provided in person or using an audiotaped protocol, involves systematic and sequential tensing and re- leasing of specific muscle groups throughout the body (Jacobson, 1938). An initial in-person session of PMR training with follow-up practice using audio- taped PMR procedures appears to be an efficient and effective means of providing this intervention (Carlson & Hoyle, 1993). For example, three ses- sions of PMR lasting approximately 25 minutes per session (one in person and two audiotaped) have been shown to be sufficient to permit individuals to apply the relaxation technique and successfully reduce physiological re- 9. PSYCHOLOGICAL INTERVENTIONS FOR ACUTE PAIN 249 sponses under stress (McCubbin et al. Interestingly, this latter work indicates that PMR may exert its stress buffering effects in part through en- dogenous opioid mechanisms, which may also be associated with analgesia (McCubbin et al. Another option for inducing a relaxed state is imagery-based interven- tions. As with PMR, a guided imagery intervention can be conducted using audiotaped instructions. Imagery instructions are usually designed to help patients develop a detailed mental image of a relaxing place on which to fo- cus their attention during the painful procedure. The imagery can be pro- vided by the therapist, or patients may be assisted in developing their own unique imagery, with the latter technique preferable. Imagery is likely to be most effective at eliciting relaxation when it incorporates multiple senses (i. A related relaxation strategy is the use of memory-based positive emotion induction procedures (Bruehl et al. This brief technique anchors a patient’s imagery in a memory of a specific event that is associated with a positive emotional state, and also involves as many senses as possible. All imagery-based strategies are likely to incorporate aspects of distraction as well as producing a relaxed, positive emotional state. Various hypnotic techniques have also been applied to management of acute pain. These techniques incorporate aspects of both traditional relax- ation procedures and imagery training, in combination with suggestions. Suggestions may be intended to induce analgesia (“your hand is insensitive, like a piece of rubber”) or to transform the pain to a non-painful sensation, such as warmth or heaviness (Farthing, Venturino, Brown, & Lazar, 1997; Wright & Drummond, 2000). Hypnotic interventions are generally adminis- tered by a trained therapist rather than by audiotape.
In response to what editors perceive as increasing control by drug companies over how the results of sponsored studies are analysed effective red viagra 200 mg, many journals now require that authors fully disclose their own roles and those of their sponsors proven red viagra 200mg. Some major medical journals will not review or publish articles based on studies that are conducted under conditions that allow the sponsor to have sole control of the data or to withhold publication. If the authors cannot satisfy these 35 Scientific Writing points, the paper will not be published. These moves are intended to prevent the publication of research results that reflect their financial backing. Role of statisticians A statistician is a person who likes to prove you wrong, 5% of the time. Taken from an internet bulletin board Statisticians often have a special place in the authorship of a paper that reflects their contribution to the design and/or reporting of the study. As such, they are a good example of how a person with specific expertise can support a study in either a minor or a major way. A statistician’s role may vary from the development of the study design and study protocol to helping prepare the grant application, implementing the study, planning and performing the data analyses, and/or interpreting the results. In general, authorship is not warranted when the statistician has contributed to only one or two aspects of the paper in an entirely consultative way. However, authorship is often warranted when the statistician has been more actively involved and has made a fundamental, intellectual contribution that fulfils at least some of the Vancouver guidelines. Author order There is intense international competition in science these days which is a kind of substitute for war. Gordon Lil and Arthur Maxwell (Science, 1959) An additional problem in deciding authorship can be the order in which coauthors are listed. The last author is usually the senior member of the team and is often the person who conceived the initial idea for the study and/or obtained funding. It is common policy that the authors in between the first and last are ranked in order of the magnitude of their input into the paper. On some papers, the last author may be the person who contributed the least in intellectual terms rather than the most. The Cochrane Collaboration specifically asks that the order reflects the size of the contribution made by each author so that the last author is the person who makes the smallest contribution. In some cases, authorship lists are extremely long but are justified by the need for collaboration between centres as 37 Scientific Writing happens, for example, in international and multicentre studies. In recent years, new methods of acknowledging teams rather than individuals and of grouping contributors have been developed as shown in Box 2.
There is now substantial empirical data for the quality-of- life literature to show that many of the patients who are in intense pain do not necessarily also have very poor quality of life generic 200mg red viagra overnight delivery. This is because the meaning of pain is very different for different people; for some cheap 200 mg red viagra overnight delivery, pain is very threaten- ing and debilitating, whereas for others with the same level of intensity, it plays a less significant role and does not appear to greatly impair their well- being or lifestyle. We need to invest in understanding the variables that me- diate this and other important factors and elucidate the impact that living with pain has on a person’s quality of life. Ultimately, quality of life is about people’s “goals expectations, standards and concerns” (WHOQOL Group, 1995) and how far these are satisfied. A person’s quality of life and well- being may impact on his or her response to pain, and vice versa (Skeving- ton, 1998; Skevington, Carse, & Williams, 2001). In addition, beliefs about quality of life may be mediated by these concepts that are heavily culturally determined (WHOQOL Group, 1995), and all the processes identified in the model impact on decision making regarding quality of life. Before summing up, two additional sections have been added to satisfy different purposes. In the first, we outline an example of a pertinent socio- cultural issue that reflects and is reflected by individual differences, and seek to show how key issues may be addressed in different ways, cutting across all levels of the model. Although no claim is made for the compre- hensiveness of the model’s components, such examples illustrate that there is some semblance of gestalt, with the whole being more than the sum of the parts. Gender was chosen as the example because it represents an important issue that has widespread influence on individual differences in terms of pain experience and report. The second section provides some limited observations on methods in this area. GENDER: AN EXAMPLE OF FEATURES THAT MAY BE ADDRESSED AT ALL LEVELS OF THE MODEL Central to the debate around gender and pain is epidemiological evidence of more frequent symptom reporting and/or help seeking by women than men (Berkley, 1997; Unruh, 1996), and the greater prevalence of certain con- ditions, like fibromyalgia, in women (Yunus, 2002). Individual differences ex- plained by gender are conceptually important at all levels of the proposed model, although there has been a tendency to focus on a limited number of gender differences at the expense of what are seen as less interesting but more frequently occurring similarities. SOCIAL INFLUENCES ON PAIN RESPONSE 199 importance of socialized gender patterns and sociocultural expectations of pain reporting and help seeking, which shape the behavior of men and women. At Levels 2 and 3, women are seen as highly social in the ways they seek out social information for decision making and actions relating to pain. In interaction with health professionals, women communicate in different styles and receive different treatments for the same conditions (Verbrugge, 1989; Verbrugge & Steiner, 1984, 1985). Differential perceptions of various aspects of quality of life (WHOQOL Group, 1995), and gendered ideologies, histories, and cultures connected with health and health care, as well as lower income, are indicated as relevant factors at Level 4. Factors addressing features from all these levels seem to be evident in Bendelow’s (1993) in-depth qualitative study, which explored women and men’s experience of and beliefs about causes of pain. Both gender groups believed that women were better able to cope with pain, and provided so- phisticated biological and sociocultural explanations for this. Bendelow also found that pain was seen as “normal” for women because of painful ex- periences associated with the reproductive process, particularly childbirth.
