Visceral pain as a triggering factor for fibromyalgia symptoms in comorbid patients

Abstract: Fibromyalgia syndrome (FMS) is a central sensitization syndrome; however, peripheral pain sources potentially exacerbate its symptoms of chronic diffuse musculoskeletal pain and hyperalgesia. This prospective study evaluated visceral pain as a possible triggering factor for FMS pain and hyperalgesia in comorbid patients. Women with (1) FMS + irritable bowel syndrome (IBS); (2) FMS + primary dysmenorrhea (Dys); (3) FMS + Dys secondary to endometriosis (Endo); (4) FMS + colon diverticulosis (Div) were compared with FMS-only women, for fibromyalgia pain (number and intensity of episodes and analgesic consumption) over comparable periods and for somatic hyperalgesia (electrical and pressure pain thresholds) in painful (tender points) and control areas (trapezius, deltoid, quadriceps muscles, and overlying subcutis and skin). In comorbid subgroups, FMS symptoms were also reassessed after treatment of the visceral condition or no treatment. All comorbid groups vs FMS-only had significantly higher FMS pain (number/intensity of episodes and analgesic consumption) and hyperalgesia in deep somatic tissues (subcutis and muscle) at all sites (0.05

So I inherited a patient on actiq and fentanyl patch for>6 years. She states its the only thing that works. I told her Actiq is usually only for cancer pain and she showed me the REMS registration that says it can be used for non cancer pain. I am still planning on telling her to find another provider because I don't feel comfortable having patients on that. Is that unreasonable of me? She has been taking the medication safely for many years but I simply do not feel comfortable with... Actiq for chronic pain

Degenerative spondylolisthesis with or without spondylolysis, multiply recurrent disk herniation, and degenerative disk disease commonly presents as back and leg pain, weakness and paresthesias. Surgical intervention, to include lumbar decompression with instrumented fusion with or without interbody fusion, is recommended to patients who are refractory to at least six weeks of nonoperative treatment, or patients with severe or progressive neurological deficits. This paper reviews the pre- and post-operative considerations, as well as the surgical technique, for a minimally invasive transforaminal lumbar interbody fusion fo...

Conclusions: HRQOL metrics can accurately predict patient satisfaction with symptoms at 3 months, 2 years, and 4 years after surgical intervention for a lumbar disk herniation. Absolute outcome scores were somewhat more predictive than change scores.

Over the last decade, much effort has been put into exploring the relationship and causality between multiple chronic diagnoses in adults, especially female adults. This research often includes endometriosis and many studies have shown increased prevalence of fibromyalgia, interstitial cystitis, irritable bowel syndrome, and migraines in patients with endometriosis compared to their counterparts without endometriosis (1). These studies have all been conducted in adult populations with a mean age usually in the 30-40  year range.

There are few subjects that can stir up stronger emotions among doctors, scientists, researchers, policy makers, and the public than medical marijuana. Is it safe? Should it be legal? Decriminalized? Has its effectiveness been proven? What conditions is it useful for? Is it addictive? How do we keep it out of the hands of teenagers? Is it really the “wonder drug” that people claim it is? Is medical marijuana just a ploy to legalize marijuana in general? These are just a few of the excellent questions around this subject, questions that I am going to studiously avoid so we can focus on two specific areas: why do...

This study comprised 9191 subjects with endometriosis, and 27 573 subjects randomly selected as controls. We individually followed‐up each subject (n = 36 764) for a 3‐year period to identify subjects subsequently diagnosed with BPS/IC. A Cox proportional hazards regression model was employed to estimate the risk of subsequent BPS/IC following a diagnosis of endometriosis. ResultsIncidences of BPS/IC during the 3‐year follow‐up period was 0.2% and 0.05% for subjects with and without endometriosis, respectively. The hazard ratio for developing BPS/IC over a 3‐year period for subjects wi...

Sometime back in 2010, a good friend of mine from college who had since become a pediatrician posted a complaint on Facebook about “made up” health conditions. “Fibromyalgia, I’m looking at you,” she wrote. At this time, pain was more of an occasional visitor in my body rather than the permanent tenant it has since become. Still, I was offended on behalf of those patients with the disease. Fast forward to today and my life is all about pacing. This is because everything I do — cook, sleep, work, walk — takes time. This gradual approach to every aspect of my life is not about enligh...

Discussion Appendicitis results from a closed loop obstruction of a blind-ending tubular structure arising from the cecum. It is a common cause of abdominal pain. It is the most frequent condition leading to emergent abdominal surgery in pediatrics. The combination of obstruction, edema, bacterial overgrowth, increased inflammatory process and increased intraluminal pressure leads to abdominal pain and possibly perforation. Appendicitis occurs in all age groups but is rare in neonates. The peak age is 6-10 years old. Pelvic inflammatory disease (PID) is an inflammatory disease of the uterus, fallopian tubes and adjacent p...
