Pain is the body鈥檚 way of telling us that something鈥檚 wrong. It may be a universal phenomenon, but everyone experiences pain differently. What causes moderate pain for one person may cause no pain for somebody else.
There are also different types of pain. There鈥檚 acute pain, the kind that happens suddenly at the time of an injury and tapers off as healing occurs. Then there鈥檚 chronic pain, which remains after recovery of an injury (or more mysteriously, the origin might even be unknown).
Pain is a complex phenomenon and there鈥檚 no one-size-fits-all approach to diagnosing and treating it. AV俱乐部 is at the forefront of pain research, with interdisciplinary research teams working to better understand and treat pain in people of all ages.
As part of next week, the Faculty of Medicine and the AV俱乐部 Medical Research Foundation will host a special panel discussion on May 26th from 12:00 to 1:00 PM ADT. will feature three AV俱乐部 researchers who are exploring the complexities of assessing, treating, and managing pain across the lifespan.
The moderator of this discussion is Joanne Bath, the CEO of the .
Panelists include:
- Dr. Christine Chambers (BSc鈥96) 鈥 clinical psychologist, Canada Research Chair (Tier I) in Children鈥檚 Pain, Scientific Director of SKIP: Solutions for Kids in Pain, and Killam Professor in the Departments of Psychology & Neuroscience and Pediatrics at AV俱乐部.
- Dr. Natalie Rosen 鈥 clinical psychologist and associate professor in the Departments of Psychology and Neuroscience and Obstetrics and Gynaecology at AV俱乐部.
- Dr. Shanna Trenaman (BScPh鈥08, MAHSR鈥14, PhD鈥20) 鈥 postdoctoral fellow with Geriatric Medicine Research at AV俱乐部 and clinical pharmacist at the Dartmouth General Hospital.
Children鈥檚 pain
Pain can be experienced as early as the day somebody is born. But until the 1980s, it was widely assumed that babies couldn鈥檛 yet feel pain. Christine Chambers, a leading expert in the area of children鈥檚 pain, will spend time discussing the evolution of our understanding of pain in children before digging deeper into the current research that informs how to assess, treat and manage pain in kids.
鈥淧ain is common in kids 鈥 it鈥檚 not just an adult problem,鈥 says Dr. Chambers. 鈥淥ne in five children experience chronic pain.鈥
She says there are three categories of pain management interventions: physical, psychological, and pharmacological. As a clinical psychologist, her research program covers psychological interventions to improve pain, such as relaxation and distraction 鈥 both of which have been shown to be very effective in managing pain. But Dr. Chambers鈥 research also explores the role that parents can play in pain management, including what they can say or do in response to their children鈥檚 pain.
Dr. Chambers has worked tirelessly to make sure the results of her research mobilize beyond scientific journal publications and conference proceedings. She wants families and clinicians to be aware of the latest evidence-based pain treatments as quickly and as easily as possible. Her efforts helped formed in 2019. It鈥檚 a national knowledge mobilization network dedicated to addressing the knowledge gap that she now leads as their scientific director. Dr. Chambers will also spend some time during the panel discussing SKIP鈥檚 work and the importance of knowledge mobilization.
Pain in older adults
Shanna Trenaman鈥檚 research dives into the pharmacological interventions for pain management in patients at the other end of the lifespan. As a clinical pharmacist, she draws on her experience caring for hospital patients to inform her research.
鈥淥lder adults are at a higher risk of having adverse drug events because they鈥檙e on many different types of drugs,鈥 explains Dr. Trenaman. 鈥淭hose drug interactions can sometimes unintentionally increase the risk of adverse side effects even further.鈥
Because of this, Dr. Trenaman has a special interest in deprescribing work for older adults, especially those with dementia. She found that in Nova Scotia alone, 20 per cent of dementia patients were prescribed a common class of pain medication called a nonsteroidal anti-inflammatory drug (NSAID). AV俱乐部 five per cent of those patients were prescribed at least two different NSAIDs. But research has shown that combining two drugs in the same class doesn鈥檛 result in better pain management. Rather, it increases the risk of that patient experiencing troublesome side effects.
鈥淎ll of a sudden we see that pain in these patients is perhaps not being adequately treated,鈥 says Dr. Trenaman, adding that it takes a lot of trial and error to treat pain in people who may no longer have the expressive language skills to describe how they鈥檙e feeling.
Dr. Trenaman will talk about the importance of optimizing medications in older age, monitoring the effectiveness of medications, and how to navigate over-the-counter pain medication purchases. Plus, she鈥檒l briefly discuss what to consider, and with whom, when deciding on what end-of-life pain management approach is best for you or your loved one.
Painful intercourse
For young and middle-aged adults who are sexually active, pain during intercourse is a lot more common than you鈥檇 expect. In fact, 20 per cent of women between the ages of 18-30 experience chronic vulvar pain during sex. In post-menopausal women, around 35 per cent. There are many different reasons for genito-pelvic pain during sex: infections, injury, hormonal changes, a history of abuse or trauma. But eight per cent of women are diagnosed with vulvodynia, which is genito-pelvic pain with no obvious origin.
Natalie Rosen, a clinical psychologist and sexual health researcher, specializes in psychological interventions for women with vulvodynia.
鈥淭here鈥檚 still a lack of knowledge about this problem,鈥 says Dr. Rosen. 鈥淲ith vulvodynia, there aren鈥檛 necessarily any physical indicators of pain鈥 so many women are likely to go through some invalidating experiences of being told there鈥檚 no sign of a problem before receiving a diagnosis.鈥
Conventional treatment for vulvodynia falls in the pharmacological category of pain management. Lidocaine, a local anaesthetic, can be applied topically to desensitize the painful parts of the genital area. It may be effective at treating the physical pain, but it doesn鈥檛 address other problems that arise with vulvodynia. Dr. Rosen says genito-pelvic pain hurts 鈥渕ore than your sex life鈥 because women suffering from pain during sex report more feelings of psychological distress, such as anxiety and depression, a lot of guilt and shame, and feelings of isolation. It also takes a toll on their relationship because their partners suffer negative impacts, too.
That鈥檚 why Dr. Rosen鈥檚 latest research study looked at managing vulvodynia pain through the use of cognitive behavioural couple therapy (CBCT). The results from that study 鈥 the very first randomized clinical trial comparing the medical intervention of lidocaine with the psychological intervention of CBCT 鈥 will be published any day now. Dr. Rosen will discuss those band-new findings in next week鈥檚 panel discussion.
