Research exploring the effects of personality and mood states on pain supports the psychological behaviorism theory’s tenet that such negative mood states influence the perception and response to pain gentle antibiotics for acne buy fabramicina with paypal. The perceived ability to control anxiety is a personality variable because it is a permanent trait antibiotics for cat acne buy 250mg fabramicina amex, and it can predict pain tolerance and endurance in individ- uals experiencing acute cold pressor pain antibiotics in poultry purchase generic fabramicina on line. Thus, individuals with low per- ceived control over anxiety tolerate less pain, show lower self-efficacy, display higher pain worry, and respond less favorably to relaxation and imaginal coping interventions. This means that anxiety management in clinical situations may attenuate the affective components of pain. In fact, an assessment of factors con- tributing to treatment outcome for chronic low back pain patients found a more profound positive effect associated with improving pain anxiety than with improving physical capacity. Anxiety may be managed by behavioral interventions (relaxation, biofeed- back, systematic desensitization, cognitive restructuring, and problem-solving) or by a variety of exposure and response prevention strategies aimed at teach- ing greater acceptance of fear, confronting anxiety directly, and preventing the patient from resorting to defensive avoidance maneuvers. The anxiety–pain link is further supported by the fact that antianxiety drugs, such as the benzo- diazepine alprazolam, reduce pain ratings of noxious electric shock, and long-acting opioid analgesics reduce anxiety. The Pain Anxiety Symptoms Scale (PASS) reliably measures the dimen- sions of anxiety that are sensitive to pain manipulation. The five factors identi- fied as comprising pain-related anxiety are catastrophic thoughts, cognitive interference, coping strategies, physiological anxious arousal, and pain escape/avoidance. The degree of pain anxiety can significantly predict toler- ance of acute pain as well as a chronic pain patient’s cognitive complaints, behavioral adjustment, physical complaints, and responsiveness to pain intervention [16, 17]. Staats/Hekmat/Staats 34 A study to determine how high and low perceived anxiety control interacts with the efficacy of pain-coping strategies split 60 participants into high or low anxiety control groups based on a median split in their scores on the Anxiety Control Questionnaire. The members of each group were then randomized to receive either emotive relaxation (inducing relaxation by evoking positive affect) treatment, emotive relaxation treatment plus pain coping instructions, or no treatment (neutral instructions). Before and after the anxiety intervention, we measured anxiety, pain, and worry. Participants rehearsed their instructions before their second hand immersion. As predicted, individuals with low anxiety control were significantly more susceptible to pain than those with high anxiety control and that the interven- tions had an independent and additive impact on pain threshold, pain tolerance, intensity, and perception. The coping intervention was more effective than the emotive treatment in attenuating pain of individuals with low anxiety control whereas those with high anxiety control responded favorably to both strategies. Supporting the additivity principle of the psychological behaviorism theory, the combined effect of two positive coping strategies created a more potent positive emotional state than either component alone could have induced. The Impact on Pain of Reducing Anger Because anger is a component of the experience of pain [19–21], sup- pressing anger and thereby increasing its intensity significantly predicts the experience of pain, lowers mood states and enhances pain. To deter- mine if managing anger through behavioral therapy facilitates pain coping, we conducted several experiments that examine the impact of various anger management techniques on pain. Anger Flooding In this study, we obtained baseline measures of cold pressor pain thresh- old, tolerance, and intensity as well as self-efficacy, pulse, worry, anxiety, anger, and mood and then randomly assigned the 60 subjects to one of three groups. The anger flooding group subjects visualized a brief hierarchy of disturbing images of recent anger-evoking experiences and their associated self-verbalizations and then received treatment for both the imaginal and verbal components of the anger-evoking stressors. The neutral imagery control partic- ipants visualized two neutral scenes, and the control group refrained from visu- alization. Then we administered a second cold pressor task and took outcome measures. As we predicted, the anger flooding intervention significantly reduced anger, distress, pain anxiety, state anxiety, trait anxiety, and worry and significantly improved mood states as well as pain threshold, tolerance, and intensity. The Psychological Behaviorism Theory of Pain Revisited 35 Anger Desensitization To explore the effects of anger desensitization on the experience of acute pain, we obtained baseline measures of cold pressor test pain, worry, anxiety, and anger and randomly assigned 60 participants to one of following interven- tions: anger desensitization (visualizing anger-evoking events while relaxing with pleasant imagery), neutral imagery control, or no-treatment control.
Syndromes
Several authors estimate that 30–54% of outpatient chronic pain patients suffer from MDD [61 antibiotics for uti during lactation purchase 250mg fabramicina with visa, 62] antimicrobial hand sanitizer quality fabramicina 500mg. This exceeds the current (5%) and lifetime (17%) prevalence estimates for MDD in the general population bacteria 5 second rule generic fabramicina 250mg. In comparing depression rates in chronic pain with other chronic medical conditions, Banks and Kerns were unable to make a definitive conclusion that MDD is more common in patients suffering with chronic pain than in other chronic medical populations. They did conclude, however, that empirical data supported the notion that higher depression rates exist among patients with chronic pain. A growing body of empirical evidence from retrospective studies suggests that chronic pain leads to depression [65, 66]. They found that pain is the strongest predictor of depression in comparison with other demographic variables. The researchers hypothesized that certain pain states may be more likely to elicit depression, though depres- sion may also be associated with the onset of specific types of pain. The observation that a greater proportion of patients with chronic pain may develop MDD than of those with other chronic medical conditions suggests that a component of the pain syndrome accounts for the higher comorbidity. Banks and Kerns proposed that chronic pain patients may think and behave dif- ferently in response to pain and that this modulation of thought may elicit depression. Specifically, the way in which a patient in chronic pain processes the pain experience (changes in life activities, duration, controllability, severity, or suffering) may predispose him/her to depression. Other factors that may contribute to depression in chronic pain patients include the type of behavior exhibited by the patient in pain as well as the response given by others to the patient’s pain behavior. Cognitive Dysfunction Concern about potential cognitive impairment is one of the main reasons for limiting the use of opioids in the elderly. The available research has not Christo/Grabow/Raja 132 demonstrated deleterious effects on neuropsychological testing or EEG except in patients who were prescribed multiple types of medications, especially seda- tives and hypnotics [68, 69]. Data on the cognitive side effects of opioid ther- apy indicate short-term effects on some aspects of cognitive functioning, but few long-term effects once stable dosing is achieved. However, a number of methodological issues weaken the strength of these conclusions and further study is warranted, particularly in specific populations, such as the elderly. Studies examining cognitive side effects of opioids generally fall into two classes: short-term exposure under laboratory or clinical conditions and long- term, stable dosing under clinical conditions. Studies of short-term exposure indicate few deleterious effects of morphine [71–73] but suggest cognitive declines may occur following short-term exposure to hydromorphone. Clinical trial data indicate slight reductions in memory, but no change in atten- tion or concentration, following 6 weeks of treatment with sustained-release morphine in patients with chronic pain. Other studies suggest that improvements in cognitive function may occur when pain is reduced with opi- oids, [75, 76] even low-dose opioids. However, patients in these studies were generally young (mean age 40 years) and benefits were not observed in a very small group of patients greater than 60 years. A recent report from our group indicates that controlled-release morphine is not associated with signifi- cant cognitive deficits in an elderly population with postherpetic neuralgia. Conclusion Recent controlled clinical trials provide evidence that opioids are effective in treating most chronic pain states, malignant and nonmalignant, over a period of several weeks. Additional studies, however, are needed to determine if these opioid analgesic effects persist over longer periods of drug therapy. Three fac- tors influence opioid responsiveness in the chronic pain population: patient- centered characteristics, pain-centered characteristics, and drug-centered characteristics. Applying these concepts to the use of opioids in treating chronic pain can help achieve maximum pain relief with limited side effects.
Consequently infection vs disease discount fabramicina amex, investigators can learn much about human emo- tion by studying mammalian laboratory animals antibiotic resistance news buy generic fabramicina 250 mg online. The limbic brain is very complex antibiotics for acne cause yeast infection best fabramicina 250 mg, and it is the central mechanism of emotion. Early investigators focused on the role of olfaction in limbic function, and this led them to link the limbic brain to emotion. PAIN PERCEPTION AND EXPERIENCE 65 what controversial term “limbic system” and characterized its functions (MacLean, 1952). He identified three main subdivisions of the limbic brain: amygdala, septum and thalamocingulate (MacLean, 1990) that represent sources of afferents to parts of limbic cortex (see Fig. MacLean postu- lated that the limbic brain responds to two basic types of input: interocep- tive and exteroceptive. These refer to sensory information from internal and external environments, respectively. Because nociception by definition involves signals of tissue trauma, it excites the limbic brain via intero- ceptive signaling. Pain research has yet to address the links between nociception and limbic processing definitively. However, anecdotal medical evidence impli- cates limbic structures in the distress that characterizes the experience of pain. Radical frontal lobotomies, once performed on patients for psycho- surgical purposes, typically interrupted pathways projecting from hypo- thalamus to cingulate cortex and putatively relieved the suffering of intrac- table pain without destroying sensory awareness (Fulton, 1951). Such neurosurgical records help clarify recent positron emission tomographic observations of human subjects undergoing painful cutaneous heat stimula- tion: Noxious stimulation activates contralateral cingulate cortex and sev- FIG. The amygdalal and septal divisions are phylogenetically older than the thalamo- cingulate division. The amygdalar division contributes to self-preservation (feeding, attack, defense). The septal division is concerned with sexual behav- ior and procreation. The thalamocingulate division contributes to sexual and family-related behaviors, including nurturance, autonomic arousal, and proba- bly some cognitive processes such as attention. Later, I describe progress in functional brain imag- ing research on pain that further elucidates the relationship of limbic activity to pain. The Autonomic Nervous System and Emotion The autonomic nervous system (ANS) plays an important role in regulating the constancy of the internal environment, and it does so in a feedback- regulated manner under the direction of the hypothalamus, the solitary nu- cleus, the amygdala, and other central nervous system structures (LeDoux, 1986, 1996). In general, it regulates activities that are not normally under voluntary control. Stimulation of the hypothalamus elicits highly integrated patterns of response that involve the limbic system and other structures (Morgane, 1981). Many researchers hold that the ANS comprises three divisions, the sym- pathetic, the parasympathetic, and the enteric (Burnstock & Hoyle, 1992; Dodd & Role, 1991). Broadly, the sympathetic nervous system makes possible the arousal needed for fight and flight reactions, whereas the parasympathetic system governs basal heart rate, metabolism, and respiration. The enteric nervous system innervates the viscera via a complex network of interconnected plexuses. The sympathetic and parasympathetic systems are largely mutual physi- ological antagonists—if one system inhibits a function, the other typically augments it. There are, however, important exceptions to this rule that demonstrate complementary or integratory relationships. The mechanism most heavily involved in the affective response to tissue trauma is the sym- pathetic nervous system.
The subspecialty of geriatric medicine is sponsored jointly by family practice and internal medicine antibiotics for lactobacillus uti order generic fabramicina line. Practitioners must be famil- 52 Opportunities in Physician Careers iar with the particular needs and treatments of an elderly client base treatment for uncomplicated uti discount fabramicina 500 mg without a prescription, as well as understanding how to use resources such as nursing homes and social services to care for the elderly antibiotic resistant bronchitis order generic fabramicina canada. Clinical and Laboratory Immunology Clinical and laboratory immunology is a subspecialty of allergy and immunology, pediatrics, and internal medicine. These subspecial- ists perform laboratory tests and complex procedures that are used to diagnose and treat diseases and conditions resulting from defec- tive immune systems. At one time, barber surgeons used their razors to open veins for bloodletting. The term “surgeon” was originally chirurgeon, from the Greek word cheir, meaning hand, and ergon, meaning work. In the eighteenth century in Europe, surgeons were seen as socially inferior to other physicians. While physicians were addressed as “doctor,” surgeons were addressed as “mister,” and this is still the case in Great Britain today. Today, general surgeons and those in eight other surgical specialties are highly trained, well-respected, well-paid members of the medical com- munity. Although general surgeons have heavy competition from the other surgical specialties, general surgery remains one of the most popular areas of specialization. It is often said in medical school that those who go into surgery seek clear-cut answers and results. They don’t like the ambiguities and gray areas that arise in internal medicine and enjoy the direct intervention of surgery. Surgery is not a specialty that creates many long-term relationships between doctor and patient. Ideally, patients who need an opera- tion improve after surgery and no longer need the surgeon’s exper- tise. Follow-up care will often be given by the patient’s primary care physician. Conditions that a surgeon typically treats include gall- bladder disease, hernia, appendicitis, breast cancer, and cancers of the digestive system. The surgeon handles everything from minor health problems to profoundly serious diseases. Surgeons operate on patients of all ages, but because of the subspecialty of pediatric surgery, in some areas of the country they treat mostly adults. There is a considerable amount of pressure in all surgical subspecialties because of the nature of the work and the responsibility that is placed upon surgeons. The average gross annual income of general surgeons in 2003 ranged from $217,000 to $291,000 a year. Average annual liabil- ity premiums for surgeons are $36,564, for example. In 2003, premiums ranged from a high of $226,500 in Florida to a low of $8,717 in Minnesota. Surgery and Surgical Specialties 55 In 2002 there were 7,412 residents working in 253 accredited residency programs in general surgery. A five-year residency in general surgery is required by the American Board of Surgery. Residents can begin their surgery training immediately upon graduating from medical school, with- out doing a residency in internal medicine first.
