Joint Commission on Accreditation of Healthcare Organizations In recent years cheap elimite 30 gm mastercard, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) has on the behalf of patients actively become involved in the issue of pain treatment 30 gm elimite sale. Acknowledging the plight of pain sufferers and the importance of adequate pain treatment to the overall well-being of patients, the Joint Commission in 1999 announced that, as of the 2001 accreditation process, physicians were expected to assess all patients, both in inhospital as well as in ambulatory-based settings, for the presence and severity of pain and to address these complaints if present. In effect, JCAHO elevated pain to the status of the fifth vital sign alongside blood pressure and heart rate. Because failure to comply with these expectations could have dire conse- quences for the accreditation status of health care systems, PCPs working in these institutions now face added pressure from administrators to ensure that chronic pain is adequately treated without necessarily receiving guidance on how opioids fit into this. Pharmaceutical Companies Pharmaceutical companies have been in the business of manufacturing therapeutic opioid medications since before the formal beginning of the indus- try, but not until the introduction of Oxycontin had the issue of pharmaceutical marketing of opioid drugs to physicians garnered such media attention. Pharmaceutical company representatives frequent doctor offices on a daily basis, plying their wares but many PCPs find their presence a necessary evil. Restrictions have been placed on what these representatives can and cannot do in order to entice physicians to prescribe the particular medication they are Opioids for Chronic Pain in Primary Care 143 promoting. However, recent lay press articles document the aggressive marketing practices of Purdue Pharma, the manufacturer of Oxycontin. While many feel that these marketing tactics were excessive, they worked to convince large numbers of PCPs to prescribe Oxycontin. Beginning with its introduction in 1995, sales of Oxycontin skyrocketed and it quickly became one of the fastest selling drugs on the market. Lack of Clear Guidelines Since the early 1990s individual pain researchers and specialty organiza- tions have produced several disease-specific guidelines for the management of chronic nonmalignant conditions such as sickle cell anemia [19, 38–41]. In 1997 the APS issued a broad consensus statement on the use of opioids in the treatment of chronic nonmalignant pain, acknowledging the lack of clear uni- versally accepted guidelines on this issue. However, existing guidelines differ in their views on the role of opioids for patients and rather than clarify- ing the situation, they have added to the confusion.

Location of Contusions of consciousness following trauma May occur from relatively low velocity impact purchase 30gm elimite free shipping, such as blows and falls Diffuse axonal injury (DAI): DAI is seen exclusively in TBI Damage seen most often in the corpus callosum and other midline structures involving the parasag- ittal white matter cheap 30gm elimite amex, the interventric- ular septum, the walls of the third ventricle and the brain stem (mid- brain and pons) (Figure 2–2) FIGURE 2–2. Locations of Diffuse Axonal Injury 50 TRAUMATIC BRAIN INJURY Responsible for the initial loss of consciousness seen in acute TBI Results from acceleration-deceleration and rotational forces associated with high-velocity impact (MVAs) The axonal injury seen in severe TBI is thought to be secondary to damage to the axo- plasmic transport in axons (with ↑ Ca++ influx) leading to axonal swelling and detachment Secondary Head Injury Brain Swelling Occurs after acute head injury within 24 hours. Vasogenic edema: – Due to outpouring of protein rich fluid through damaged vessels – Extracellular edema – Related to cerebral contusion 2. Cytogenic edema: – Found in relation to hypoxic and ischemic brain damage – Due to failing of the cells’ energy supply system ↑cell-wall pumping system ⇒ intracellular edema in the dying cells PENETRATING HEAD INJURIES Missile/Fragments Deficits are focal corresponding to location of lesions caused by bullet/fragment If the brain is penetrated at the lower levels of the brain stem, death is instantaneous from respiratory and cardiac arrest. Risk of long-term posttraumatic epilepsy is higher in penetrating head injuries compared to nonpenetrating injuries RECOVERY MECHANISMS Plasticity Brain plasticity is when the damaged brain has the capabilities to repair itself by means of morphologic and physiologic responses Plasticity is influenced by the environment, complexity of stimulation, repetition of tasks, and motivation It occurs via 2 mechanisms: 1) Neuronal regeneration/neuronal (collateral) sprouting 2) Unmasking neural reorganization TRAUMATIC BRAIN INJURY 51 Neuronal Regeneration Intact axons establish synaptic connections through dendritic and axonal sprouting in areas where damage has occurred May enhance recovery of function, may contribute to unwanted symptoms, or may be neutral (with no increase or decrease of function) Thought to occur weeks to months post-injury Functional Reorganization/Unmasking Healthy neural structures not formerly used for a given purpose are developed (or reas- signed) to do functions formerly subserved by the lesioned area. Brain plasticity—remember “PUN” Plasticity = Unmasking + Neuronal sprouting OTHER RELATED PHENOMENA ASSOCIATED WITH HEAD INJURY RECOVERY Synaptic Alterations Includes diaschisis and increased sensitivity to neurotransmitter levels Diaschisis: Mechanism to explain spontaneous return of function (Figure 2–3) 1. Lesions/damage to one central nervous system (CNS) region can produce altered function in other areas of the brain (at a distance from the original site of injury) that were not severed if there is Injury (Site A) connection between the two sites Altered function also occurs here (Site B) (through fiber tracts). There is some initial loss of func- was not severed by the initial injury and is distant from tion secondary to depression of the original site of injury (site A). Recovery of functions areas of the brain connected to controlled by site B will parallel recovery of site A the primary injury site, and reso- lution of this functional deaffere- nation parallels recovery of the focal lesion (Feeney, 1991). Functional Substitution/Behavioral Substitution Techniques/new strategies learned to compensate for deficits and achieve a particular task Other Theories of Recovery Include Redundancy: Recovery of function based on activity of uninjured brain areas (latent areas) that normally would contribute to that function (and are capable of subserving that function) Vicariation: Functions taken over by brain areas not originally managing that function. Lesions that interrupt the metabolic or structural integrity of the RAS or enough of the cortical neurons receiving RAS projections can cause coma. DISORDERS OF CONSCIOUSNESS Coma It is a state of unconsciousness from which the patient cannot be aroused; there is no evi- dence of self- or environmental-awareness Coma is essentially universal in severe TBI Up to 50% of patients in coma > 6 hours die without ever regaining consciousness. Survivors who remain unresponsive for > 2–4 weeks evolve into vegetative state Eyes remain continuously closed No sleep-wake cycles on electroencephalogram (EEG) There is no spontaneous purposeful movement (e. Persistent VS VS present ≥ 1 month after TBI or Nontraumatic brain injury Permanent VS VS present > 3 months after Nontraumatic brain injury or VS present > 12 months after TBI, in both children and adults American Congress of Rehabilitation Medicine (1995)—advocates to simply use the term vegetative state (VS) followed by the length of time it persists instead of the terms persis- tent and permanent. The Aspen Neurobehavioral Conference (1996), supported the ACRM recommendations to use the term VS + specify cause of injury + specify length of time since onset.
