3 The aches of the psyche … I do not like my state of mindI'm bitter, querulous, unkind.I am always anxious and tensemy thoughts make no senseI dread the dawn's recurrent light;I hate to go to bed at night.I find no peace in paint or typeMy world is but a lot of tripe.I'm disillusioned, empty-breastedFor what I think, I'd be arrested.I am not sick, I am not wellMy quondam dreams are shot to hell.My soul is crushed, my spirit sore;I do not like me any more.I want to stop this pain … before I turn insaneAdapted poems

6 Why Pain, psychological distress (Anxiety and Depression)? Anxiety, Depression and Pain Symptoms are highly prevalent conditionsLifetime prevalence of Pain = 24-37%1Lifetime prevalence of Depression = 5-10%2Lifetime prevalence of Anxiety= 20%2Anxiety, Depression and Pain complicate each other, affect outcomes, cause more morbidity and disability and increase costs.Regier DA, Myers JK, Kramer M, et al.

The prevalence of depression in pain disorders In general population pain = 18% (4.7%-22%)In Primary Care clinics = 27% (5.9%-46%)In pain clinics = 52% (1.5%-100%)In orthopedic clinics = 56% (21%-89%)In dental/facial pain clinics = 85% (35%-100%)In gynecology pelvic pain clinics = 13% (12%-17%)Prevalence of anxiety disorders in patients with chronic painIn general population= 35 % back pain clinic = 20% - 57% [3,4]1- Matthew et al Arch Intern Med. ;163: , 20032- Manchikanti et al Pain Physician, Volume 5, Number 2, pp , 20023- Sommer 18th European Congress of Psychiatry.

32 “For several years I have been aware of my own mortality, for some strange reason it had been on my mind…Since I have had this deteriorating back problem which causes constant pain and …… a barrier of intimacy … . I had two spinal interventions to cure the pain, I had great disappointment when the first failed, and was devastated when the second failed, ….I was told nothing… I have had one hope and now it is gone …. this feels like the sword of Damocles …. How long it will be another day, month, several months? Before I…..”Jan 2008

39 Induction of Negative Mood Disrupts Emotion Regulation Neurocircuitry and Enhances Pain UnpleasantnessNegative or neutral moods were induced in healthy volunteers who underwent heat pain whilst in an fMRI scanner.Pain was rated more unpleasant after the sad mood induction. Depressed mood was associated with increases in negative pain-related cognitions (catastrophizing)Background: Depressed mood alters the pain experience. Yet, despite its clear clinical relevance, little is known about the cognitive and neural mechanisms underlying this phenomenon. We tested an experimental manipulation to unravel the interaction between depressedmood and pain. We hypothesized that dysregulation of the neural circuitry underlying emotion regulation is the mechanism whereby painprocessing is affected during depressed mood.Methods: Using functional magnetic resonance imaging, we compared the effects of sad and neutral cognitive mood inductions on affective pain ratings, pain-specific cognitions, and central pain processing of a tonic noxious heat stimulus in 20 healthy volunteers.Results: The increase in negative pain-specific cognitions during depressed mood predicted the perceived increase in pain unpleasantness. Following depressed mood induction, brain responses to noxious thermal stimuli were characterized by increased activity in a broad network including prefrontal areas, subgenual anterior cingulate cortex, and hippocampus, as well as significantly less deactivation whencompared with pain responses in a neutral mood. The participants who reported the largest increase in pain unpleasantness after the sadmood induction showed greater inferior frontal gyrus and amygdala activation, linking changes in emotion regulation mechanisms withenhancement of pain affect.Conclusions: Our results informhowdepressedmoodand chronic pain co-occur clinically and may serve to develop and translate effectiveinterventions using pharmacological or psychological treatment.Areas that showed increased activity during pain in the depressed mood state - left insula, thalamus, hippocampus, IFG, dlPFC, OFC, and the sACC. The thalamus and the insular cortex are part of the afferent nociceptive network.dlPFC, dorsolateral prefrontal cortex; IFG, inferior frontal gyrus; OFC, orbitofrontal cortex sACC – subgenual anteria cingulate cortexBerna C et al.

43 Risk of iatrogenic addiction in patients treated with opioids A systematic review 41 studies with conflicting findings Risk can be relatively high (>10%) or low (<0.1%). A systematic review noted the prevalence of Lifetime SUD 36% to 56%Current SUD 43%Aberrant medication-taking behaviours 5% to 24%Risk factors for opioid abuse in patients with chronic pain are :young age,male gender,past alcohol or cocaine abuse,previous drug conviction,mental health disorders,pain in multiple regions,pain after MVA Wasan et al  Martell et al 2007 Højsted & Sjøgren
44 Opioid treatment; may need a revisit A large population-based study found that opioid usage was significantly associated with:more severe pain,poorer self-rated health,lower quality of life,less physical activity,lower employment,higher levels of health careutilization, andmore subjects living aloneimpaired neuropsychological performance reaction times, psychomotor speed, and working memoryHøjsted & Sjøgren Curr Opin Anaesthesiol Oct;20(5):451-5.

58 Conclusion:Despite the frequent coexistence of depression , anxiety and pain the magnitude and implications of that relationship are still unclear.Neglecting the treatment of fatigue, low energy , and painful physical symptoms in depressed patients can lead to unsatisfactory outcomes, characterized by a failure of depressed patients to return to normal social and occupational functioning.Keller MB et al 1992 , Judd LL et all 1998, Angst J 1992and Kupfer DJ 1991; Sheline YI et al 1996; Blier P et al. 2001
