Descartes’s (1644/1985) early mechanistic conceptions of pain resulted in the biomedical specificity theory that proposed that a specific pain system transmits messages from receptors to the brain purchase gyne-lotrimin 100 mg online. This theory is sometimes referred to as “the alarm bell” or “push button” theory (Melzack generic 100 mg gyne-lotrimin fast delivery, 1973), INTRODUCTION 3 because of its apparent simplicity. Descartes’s early views were refined substantially over the years, and more complex mechanistic views gradu- ally emerged as investigators struggled to incorporate in their models of pain the complexities and puzzles of pain that dismayed patients and clini- cians struggling with pain control. Nevertheless, biomedical specificity theory continued to exert an enormous influence through the first half of the 20th century. There was little room for recognition of the importance of psychological processes such as emotion, attention, past experience, and cognitive processes in the study of pain. Patients suffering from pain without a pathophysiological basis or signs often were considered “crocks” (Melzack, 1993). Despite dominance of sensory specificity and biomedical models of pain, clinicians were increasingly finding emotional and motivational processes to be important in understanding pain. Merskey (1998) observed that psy- chological explanations about motives for complaints about pain and psy- chodynamic theories gradually became popular during the early and mid- dle parts of the 20th century (e. Early investigation of psychiatric patients with pain had led to the erroneous conclusion that physical and psychological factors in pain were mutually exclusive and that pain is either physical or psychologi- cal (IASP Ad Hoc Subcommittee for Psychology Curriculum, 1997). Persis- tent pain with no identifiable causes was frequently labeled as psychogenic, a regrettable construct because it perpetuates mind/body dualistic thinking (Liebeskind & Paul, 1977) and fails to recognize that biological mechanisms are integral to all psychological phenomena, including pain. Freud (1893–1895) viewed pain as a common conversion symptom and favored the position that pains encountered in hysteria were originally of somatic origin. In other words, he argued that the pain was not created by the neurosis, but rather the neurosis served to maintain it. Dynamic con- ceptions of pain emphasize the role of psychic energies derived from innate drives linked to aggression, dependency, and sexuality and postulate that the pain experience is associated with the gratification or frustration of these drives (Pilowsky, 1986). For example, pain can be construed as the product of aggression that is inflicted either on oneself or on others and can be related to the formation of a cruel superego with an associated chronic sense of guilt and low self-esteem (Pilowsky, 1986).

The segmenta- tion defects usually occur at the level of C5/C6, but can also occur at C2/C3 level.

Chronic exercise attenuates this Marathon runners have a higher incidence of self- response cheap 100 mg gyne-lotrimin visa, but macrophage function is greater than reported upper respiratory tract infections (URI’s) after in nonathletes (Woods et al purchase gyne-lotrimin 100 mg, 1999).

A similar study of healthy, elderly people noted an infections, however. A follow-up study (Gleeson et al, inverse relationship between the amount of energy 2000) showed no correlation between salivary IgA expended in daily moderate activities and URI levels and infection risk. Runners in short races (5K, 10K, half-marathon) decreased salivary IgA an average of 27. There was a negative correlation found running 16–26 mi a week increased the risk between salivary IgA levels and number of days of ill- of having ≥1 URI compared to running <9 mi a ness and flu symptoms, but not days of cold symptoms. Running 9–16 mi or >26 mi a week con- Studies of immune marker changes with exercise have ferred intermediate risk. Moderate exercise lowers infection risk to below that of being sedentary, while strenuous In premenopausal women, no exercise or a 15-week exercise imposes the highest risk of all (Nieman, walking program made no difference in NK cell 2002). NKCA was significantly increased in the More evidence is needed, however, as the link training group at 6 weeks, but was elevated equally in between moderate exercise and infection is less clear both groups at 15 weeks. Most studies of infection 50% fewer days with URI symptoms, but the same and exercise are relatively small and rely on patient number of separate URIs compared to controls. Also, other fac- NKCA at 6 weeks was negatively correlated with URI tors such as pathogen exposure, stress, sleep, nutri- symptom days (Nieman et al, 1990b). The exercise group, however, had significantly fewer URIs than the control group (3/14 vs. A comparison group of elite elderly athletes had significantly higher NKCA and lymphocyte activity and even fewer URIs (1/12). NKCA and lymphocyte proliferative response were significantly higher in the rowers. Days of self-reported URI symptoms, however, were similar in both groups and did not correlate with immunologic changes. Transillumination and FEVER radiographs of the sinuses are generally not useful (Fagnan, 1998).
