This im- plies that the elements of mental capacity and adequate information should also be present (Rozovsky proven 1000 mg valtrex, 1990) buy 500 mg valtrex otc. However, it is not always possible to clearly determine what constitutes “adequate information” in situations where consent is being sought. In making this determination it is important to know the type of information that potential research participants expect and want. Casarett, Karlawish, Sankar, Hirschman, and Asch (2001) set out to clarify this issue by presenting pain patients with vignettes describing various research studies and subsequently interviewing them about the type of information they would have liked to have had before enrolling. Par- ticipants stressed the need for information about study-related changes in medications, contingency plans, and assurances about how increased pain would be treated. They also raised concerns about addiction to opioids as a result of participation in the study (this is likely to arise when psychologists conduct research within the context of broader studies involving medical professionals). Most patients indicated that they would want to know how knowledge generated from their study might help them, as well as about burdens and inconveniences associated with study participation. Thirty- eight percent stated that they would like to know how study participation might give them improved access to a health care provider, 55% desired information about treatment availability following the completion of the study, 62% desired information about changes in medication and dose, 78% of patients described concerns about increased pain as a result of study participation, 70% said that they would want information about previous re- lated studies of the treatment, and all patients indicated that they wanted information about potential treatment risks and side effects. Patients also wished to know whether they would have continued access to the treat- ment used in the study after the trial is over. Similar investigations focusing specifically on psychological studies of pain would be useful. With respect to the IASP guidelines concerning the importance of written consent, we note that for some cultural groups in our society written con- sent may not be considered appropriate. In some instances, for example, it may be appropriate (for research ethics boards and institutional review committees) to approve consent by traditional native ceremony as long as this is fully voluntary and informed. Even in such instances, it would impor- tant to supply those consenting with all pertinent information about the study in writing. According to the IASP (1995) document, special precautions should be taken with vulnerable populations.

In contrast valtrex 500mg amex, burn injury to tissues below the glottis and upper trachea was not observed in any of their patients discount valtrex 500 mg otc. Thermal injury below the glottis is limited by the very efficient heat-exchanging function of the upper airway. In the same way that the upper airways heat and humidify cool dry inspired air, the lower airways are also protected from extreme heat. An exception is exposure to steam, which has a much greater heat capacity than that of dry gases and can overwhelm protection by the upper airway mucosa. Inhalation of steam can pro- duce thermal injury throughout the major bronchioles. An additional protective mechanism is reflex laryngeal closure in response to intense thermal or chemical irritation in conscious victims. Unconscious victims lack this protection and are more vulnerable to inhalation injury. Thermal injury to the lower airways and pulmonary parenchyma implies exposure to very intense heat and is usually rap- idly fatal. Areas of blistering, ulceration, hemorrhage and rapidly developing edema can be ob- served soon after injury. The pharyngeal mucosa offers little resistance to edema TABLE 1 Three forms of inhalation injury Thermal Injury (usually before vocal cords) Chemical irritation Systemic toxicity 58 Woodson et al. Heat denatures tissue proteins that activate complement and initiate a cas- cade of inflammatory mediator release and activation. Most of the variables of the Starling equation are altered in favor of increased transvascular fluid flux. Capillary permeability is greatly increased (reduced reflection coefficient), micro- vascular hydrostatic pressure is increased, interstitial hydrostatic pressure de- creases, and there is an increase in interstitial oncotic pressure. As plasma proteins are lost at the burn injury sites and resuscitation progresses, with large volumes of crystalloid plasma colloid oncotic pressure decreases dramatically. Lymphatic drainage is soon overwhelmed and interstitial volume increases (edema forma- tion).

However generic valtrex 500 mg with mastercard, 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 order 1000 mg valtrex otc. 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. Studies on the analgesic efficacy of NMDA antagonists in human pain states reveal both a reduction in pain (ketamine) and no difference in pain (DM). Animal studies, however, suggest a more convincing role for the use of NMDA antagonists in treating chronic pain. The abuse potential and concerns about addiction in the chronic pain population may be reduced by frequent and comprehensive assess- ments of aberrant behavior. The prevalence of illicit drug use in the chronic pain population may be higher than in the general population; therefore, clinicians should monitor patterns of aberrant drug behavior as well as urine toxicology Opioids in Chronic Pain 133 results to ensure compliance with opioid treatment. Patients in chronic pain exhibit a high prevalence of MDD that demands concurrent treatment to avoid functional disability. Controversy continues over a causal relationship between chronic pain and depression; yet, clinical evidence suggests that chronic pain exacerbates depressive symptomatology.
