Vaccines Smallpox vaccine contains live vaccinia virus, a virus in the orthopoxvirus family and closely related to variola virus, the agent that causes smallpox. Immunity resulting from immunization with vaccinia virus (vaccination) protects against smallpox. The Committee also noted that, at that time, several countries were contemplating the need to produce more vaccine stocks. Now, a number of governments have chosen to examine their stocks, test their potency, and consider whether more vaccine is required. The vaccine is then freeze dried and sealed in ampoules for later re-suspension in sterile buffer and subsequent intradermal inoculation by multiple puncture with a bifurcated needle. This Centre also tests batches of the smallpox vaccine for potency every five years. Duration of protection following vaccination Vaccination usually prevents smallpox infection for at least ten years. If symptoms appear, they are milder and mortality is less in vaccinated than in nonvaccinated persons. Even when immunity has waned, vaccinated persons shed less virus and are less likely to transmit the disease. Complications of vaccination Existing vaccines have proven efficacy but also have a high incidence of adverse side-effects. The risk of adverse events is sufficiently high that vaccination is not warranted if there is no or little real risk of exposure. Vaccine administration is warranted in individuals exposed to the virus or facing a real risk of exposure (see above). A safer vaccinia-based vaccine, produced in cell culture, is expected to become available shortly. Should national authorities decide that the risk of epidemic spread is so great that such groups should receive protection, it may be advisable to attempt to limit adverse effects through intramuscular administration of vaccinia immune globulin, if available, from vaccinia-infected sheep or calves. About the Virus the causative agent, variola virus, is a member of the genus Orthopoxvirus, subfamily Chordopoxvirinae of the family Poxviridae. If aerosolized, it probably retains its infectivity for at least several hours if not exposed to sunlight or ultraviolet light. The size of the genome makes it especially difficult to create a synthetic copy of the virus. If site is obviously dirty, a cloth moistened with water may be used to wipe the site. A sterile bifurcated needle (which must be cool) is inserted into the ampoule of reconstituted vaccine. On withdrawal, a droplet of vaccine, sufficient for vaccination, is contained within the fork of the needle. For both primary and revaccination, 15 up and down (perpendicular) strokes of the needle are rapidly made in the area of about 5mm in diameter (through the drop of vaccine deposited on the skin). The strokes should be sufficiently vigorous so that a trace of blood appears at the vaccination site. Although it is desirable not to induce frank bleeding, the proportion of successful takes is not reduced if bleeding does occur. Unused, reconstituted freeze-dried vaccine should be discarded at the end of each working day. Complications of vaccination Four main complications are associated with vaccination, three of which involve abnormal skin eruption. Eczema vaccinatum occurred in vaccinated persons or unvaccinated contacts who were suffering from or had a history of eczema. In these cases, an eruption occurred at sites on the body that were at the time affected by eczema or had previously been so. The prognosis was especially grave in infants having large areas of affected skin. Progressive vaccinia (vaccinia necrosum) occurred only in persons who suffered from an immune deficiency. Postvaccinial encephalitis, the most serious complication, occurred in two main forms. The first, seen most often in infants under 2 years of age, had a violent onset, characterized by convulsions. Recovery was often incomplete, leaving the patient with cerebral impairment and paralysis. The second form, seen most often in children older than 2 years, had an abrupt onset, with fever, vomiting, headache, and malaise, followed by such symptoms as loss of consciousness, amnesia, confusion, restlessness, convulsions and coma. The best estimates of the frequency of these complications come from a 1968 study conducted by the United States involving over 14 million vaccinated persons. Sixty additional cases of eczema vaccinatum occurred in contacts of vaccinated persons, with one death. On the basis of this study, it was estimated that approximately one death per million resulted from complications following primary vaccination and one death per four million following revaccination. This is difficult to answer with great precision, as all available data come from the time prior to the global eradication of smallpox, which was certified in 1979. When smallpox was still occurring naturally, populations in endemic countries were exposed to the virus. In some countries, subclinical infection with the virus occurred rather frequently among vaccinated persons, thus boosting their immunity. Edward Jenner, who developed the vaccine in 1798, believed that successful vaccination produced lifelong immunity to smallpox. This is why, prior to the certification of eradication, periodic revaccination was recommended, for example, for international travellers. Vaccination five years prior to exposure provides a high level of protection against smallpox. High levels of protection are generally believed to last 10 years after vaccination. Beyond this 10-year interval, where the evidence of protection is strong, the data are conflicting and difficult to interpret. Some studies found some degree of protection against smallpox for as long as 30 years after vaccination. However, other studies demonstrated very little or no immunity 20 years after vaccination. A large study, published in 1913, found substantial protection even in persons, vaccinated as children, aged more than 50 years. Smallpox eradication was a global campaign, and populations were protected by vaccination in every country. However, during the campaign, different forms of smallpox occurred, and different vaccines and vaccination techniques were used. The duration of protection can be influenced by the potency of the vaccine and the inoculation procedure used. These factors make it difficult to give firm, precise estimates that are relevant today, where populations no longer have widespread immunity, either from vaccination or from having survived the disease (patients who survived smallpox were immune for life). Another factor that makes it difficult to make projections today based on historical data is the much larger pool of persons suffering from weakened immune systems.

Conclusion Glossary Bibliography Biographical Sketches Summary Pain is defined by the International Association for the Study of Pain as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Pain may be described according to severity (mild, moderate, severe), duration (acute or chronic) or type (nociceptive, inflammatory, neuropathic). In the last two decades, considerable research directed at enhancing our collective understanding of the neurobiology of pain has revealed that persistent ongoing pain secondary to tissue inflammation or peripheral nerve injury is underpinned by considerable complexity and plasticity in the pain signaling system. Following tissue or peripheral nerve injury, there is sensitization of the somatosensory system so that innocuous stimuli are detected as painful (allodynia) or there is a heightened response to painful stimuli (hyperalgesia). Although a large number of pain targets for potential modulation by small molecules or biologics have been identified with several of these molecules now in preclinical or clinical development, these potential new pain medicines are yet to reach the clinic. For mild pain, non-opioid analgesics such as paracetamol (acetaminophen) and nonsteroidal anti-inflammatory drugs are recommended, with adjuvants. For moderate pain, weak opioids such as codeine and tramadol are added to non-opioids and/or adjuvants, as required. For moderate to severe pain, strong opioids are recommended with morphine as the drug of choice due to its ready availability worldwide at low cost. Strong opioids may be co-administered with non-opioids and with adjuvants, as required. In the next decade, a new generation of pain medicines is likely to reach the market, thereby expanding the armamentarium of drugs available to clinicians for the management of persistent on-going pain. Instead, a number of pain rating scales have been devised and validated for quantifying changes in pain severity within individuals (Melzack and Katz, 2006). Acute pain such as that which occurs following surgery, trauma, burns or myocardial infarction, may be regarded as an adaptive response with a physiologically important role. The first phase (lasting seconds) alerts the individual to potentially dangerous stimuli and the second, subchronic phase (lasting hours to days) may be regarded as a protective mechanism characterized by guarding of the injured tissue as a means of promoting healing and recovery (Merskey and Bogduk, 1994). It commonly persists beyond the time of healing of an injury and frequently there may not be any clearly identifiable cause (Merskey and Bogduk, 1994). Persistent pain is often regarded as a maladaptive response that confers no physiological advantage, such that the pain state itself has become the disease, requiring treatment (Cousins, 2007). Persistent pain may have multiple components including nociceptive pain, inflammatory pain and neuropathic pain, which are variously defined as follows (Devor and Seltzer, 1999): 1. South specialized primary afferent nerve fibres (nociceptors) located in undamaged or previously undamaged skin, viscera and other organs in the absence of sensitization. The most common types of central neuropathic pain are post-stroke pain, pain in multiple sclerosis and spinal cord injury pain. At present, persistent inflammatory and neuropathic pains present great challenges to general practitioners and pain specialists alike, because the currently available drugs used to treat these conditions have significant limitations. Moreover, opioids that are effective for the relief of moderate to severe nociceptive pain are often considerably less effective for the relief of neuropathic pain, particularly when administered by systemic routes. By contrast, in the last two decades, there have been considerable advances in our collective understanding of the neurobiology of pain, particularly persistent pain, which has revealed many novel potentially druggable targets for the development of new pain therapeutics for human use (Pace et al. Hence, this chapter has been structured in two parts, with the first providing an overview of the pain signaling system, highlighting recent advances in our understanding of the neurobiology of pain with emphasis on potential targets for the development of new pain therapeutics. The second provides an overview of medications currently used for managing acute and chronic pain. Nociceptive signals are then relayed from the dorsal horn by second-order neurones via spinothalamic tracts to higher centres in the brain, which may in turn activate descending inhibitory mechanisms to reduce the severity of the perceived pain to tolerable levels (Figure 1) (Sherrington, 1906; Dubner, 2004; Yaksh, 2006). Additionally, cutaneous mechanoreceptors are often supplied by large (> 10 m), fast (30-100 m/s) myelinated Afibres that, in the absence of tissue or nerve injury, are responsive only to touch, vibration, pressure and other modes of non-noxious, low intensity mechanical stimuli (Woolf et al. Generally, a single discharge of an individual nociceptor is not perceived as noxious and many nociceptors need to be recruited for pain to be perceived (Millan, 1999; Willis and Coggeshall, 2004). However, in the presence of persistent inflammation or nerve injury, Afibres undergo phenotypic change such that non-noxious stimuli may become encoded as noxious stimuli (Dubner, 2004). The axons of these primary afferent sensory neurones give rise to a peripheral branch that innervates various tissue types and a central branch that travels through a dorsal root to enter the spinal cord and synapse with second-order neurones (Todd and Koerber, 2006). Fibres that innervate skin are referred to as cutaneous sensory neurons, whereas afferent fibres inervating abdominal or pelvic viscera are termed visceral afferents (Todd and Koerber, 2006). Together, these primary sensory neurones are a means for providing ongoing surveillance of the external environment as well as the ongoing state of the body itself (Todd and Koerber, 2006). Nociceptive signals are detected by specialized primary afferent nerve fibres (nociceptors) located in the injured peripheral tissue from where they are transmitted to the dorsal horn of the spinal cord. Nociceptive signals are then relayed to higher centres in the brain, which may result in activation of the descending inhibitory system to reduce the severity of the perceived pain. However, it should be noted that myelinated and unmyelinated fibres that signal the presence of innocuous mechanical and thermal stimuli also project to these same laminae (Todd and Koerber, 2006). Low-threshold Amechanoreceptors terminate in deeper laminae (Willis and Coggeshall, 2004). At the level of individual nerve territories, the map is organized such that neighbouring peripheral fields occupy contiguous parts of the spinal cord (Woolf and Salter, 2006). South from the spinal cord to the brain, they represent a small minority of the total number of cells in the dorsal horn (Woolf and Salter, 2006). Those in lamina I and many of those from deeper laminae have axons that cross the midline and ascend to a variety of supraspinal targets including the thalamus, midbrain periaqueductal grey matter, lateral parabrachial area of the pons and various parts of the medullary reticular formation (Todd and Koerber, 2006). Projection neurons are also involved in the activation of descending control systems, which in turn modulate dorsal horn neurons through both excitatory and inhibitory mechanisms (Woolf and Salter, 2006). Many inhibitory interneurons are spontaneously active, and in this way maintain an ongoing tonic inhibitory control over dorsal horn nociceptive processing (Woolf and Salter, 2006). Significantly more vomiting occurred with morphine, whereas constipation was more common with oxycodone.

Surprisingly, doubt claims on the speed with which this will hap however, distinguished researchers still allow them pen. The more important caveats, however, are of a selves to get carried away with the excitement of different kind. First, nd there was a report that one of the genes responsible ing the susceptibility genes is the relatively easy part. Research will be needed in three broad areas: search, however, had not taken into account strati transcriptomics (the study of which genes are switched cation biases, and some years later it still remains on in particular cells), proteomics (which looks at the unconrmed by independent investigators.
