Pain is common in Parkinson's disease (PD). In general and chronic pain populations, physical inactivity, poor sleep, and anxiety are associated with worse pain. However, little is known about these potential predictors of pain in PD.
Learn More >Up to 90% of people with neurological deficits following whiplash injury report chronic symptoms. A recent unique study of neck-specific exercise showed positive results (post-intervention at 12 weeks), regarding arm pain and neurological deficits in people with chronic whiplash associated disorders (WAD). This 1-year follow-up of that randomised controlled study with assessor blinding aimed to examine whether neck-specific exercise with (NSEB) or without (NSE) a behavioural approach has long-term benefits over physical activity prescription (PPA) regarding arm pain and neurological deficits (n = 171). Interventions were: NSE, NSEB, or PPA. Follow-up of arm pain, paraesthesia bothersomeness (questionnaires) and clinical neurological tests were performed after 3, 6 and 12 months and analysed with Linear Mixed Models and General Estimating Equations. The NSE and/or NSEB groups reported significantly less pain and paraesthesia bothersomeness as well as higher odds of normal key muscle arm strength and of normal upper limb neural tension over the year (all p < 0.03), compared with PPA. In conclusion, results suggest that neck-specific exercise with or without a behavioural approach may have persisting long term benefits over PPA regarding arm pain and clinical signs associated with neurological deficits in chronic WAD.
Learn More >This study aimed to understand long-term changes of the osteoarthritic temporomandibular joint (TMJ) condyle using computed tomography (CT) and to verify its correlation with clinical characteristics of temporomandibular disorders. Eighty-nine patients (152 joints; 76 female, 13 male) who had taken follow-up CTs (mean follow-up period: 644.58 ± 325.71 days) at least once in addition to their initial evaluation were selected. Cross-sectional demographic and clinical data and longitudinal CT images were collected. Data were analyzed by analysis of variance and logistic regression. Overall destructive change index (number of TMJ condyle sections in which destructive change was observed) decreased from 1.56 to 0.66. Improvement was seen in 93 joints (61.2%) and 27 joints (17.8%) worsened. In the pain positive group, both initial and final destructive change index were significantly higher compared to the pain negative group (p = 0.04). Occlusal stabilization splint therapy and nonsteroidal anti-inflammatory drug administration showed a significant effect on improving the prognosis of TMJ osteoarthritis (p = 0.015 and 0.011). In conclusion, TMJ osteoarthritis showed long-term improvement in the majority of cases. TMJ osteoarthritis accompanied by pain showed unfavorable prognosis with additional bone destruction. Occlusal stabilization splint and nonsteroidal anti-inflammatory drug administration were beneficial on the prognosis of TMJ osteoarthritis.
Learn More >Very little is known regarding the prevalence of opioid induced hyperalgesia (OIH) in day to day medical practice. The aim of this study was to evaluate the physician's perception of the prevalence of OIH within their practice, and to assess the level of physician's knowledge with respect to the identification and treatment of this problem.
Learn More >Pain persists in a moderate number of patients following hip or knee replacement surgery. Persistent pain may subsequently lead to the prolonged consumption of analgesics after surgery and expose patients to the adverse drug events of opioids and NSAIDs, especially in older patients and patients with comorbidities. This study aimed to identify risk factors for the increased use of opioids and other analgesics 1 year after surgery and focused on comorbidities and surgery-related factors.
Learn More >Pancreatic ductal adenocarcinoma (PDAC) is frequently accompanied by excruciating pain, which has been associated with attraction of cancer cells and their invasion of intrapancreatic sensory nerves. Neutralization of the chemokine CCL2 reduced cancer-associated pain in a clinical trial, but there have been no systematic analyses of the highly diverse chemokine families and their receptors in PDAC.
Learn More >Omiganan is an indolicidin analogue with antimicrobial properties that could be beneficial for patients with atopic dermatitis. This randomized, double-blind, placebo-controlled phase II trial explored efficacy, pharmacodynamics and safety of topical omiganan once daily in 36 patients with mild to moderate AD. Patients were randomized to apply topical omiganan 1%, omiganan 2.5% or vehicle gel to one target lesion once daily for 28 consecutive days. Small but significant improvements of the local oSCORAD index and morning itch were observed in the omiganan 2.5% group compared to the vehicle gel group (-18.5%; 95%CI=-32.9,-1.0; p=0.04 and -8.2; 95%CI=-16.3,-0.2; p=0.05 respectively). A shift from lesional to non-lesional skin microbiota was observed in both omiganan treatment groups, in contrast to the vehicle group. In conclusion, treatment with topical omiganan improved dysbiosis in patients with mild to moderate atopic dermatitis and small but statistically significant improvement of clinical scores were detected. Our findings warrant further exploration in future clinical trials.
Learn More >Research suggests that itch and psychiatric diseases are intimately related. In efforts to examine the prevalence of psychiatric diagnoses in patients with chronic itch not due to psychogenic causes, we conducted a retrospective chart review of 502 adult patients diagnosed with chronic itch in an outpatient dermatology clinic specializing in itch and assessed these patients for a co-existing psychiatric disease. Psychiatric disease was identified and recorded based on ICD-10 codes made at any point in time which were recorded in the patient's electronic medical chart, which includes all medical department visits at the University of Miami. Fifty-five out of 502 (10.9%) of patients were found to have a comorbid psychiatric diagnosis based on ICD-10 codes. The most common psychiatric diagnoses were anxiety disorders (45.5%), followed by major depressive disorder (36.4%). There was no significant association of any specific type of itch to a particular psychiatric disorder. No unique itch characteristics were noted in patients with underlying psychiatric diagnoses.
Learn More >The fear-avoidance model of chronic pain holds that individuals who catastrophize in response to injury are at risk for pain-related fear and avoidance behavior, and ultimately prolonged pain and disability.
Learn More >To determine whether alcohol intake is associated with occurrence of headaches on the following day. In this prospective cohort study, adults with episodic migraine completed electronic diaries every morning and evening for at least six weeks in March 2016-October 2017. Every day, participants reported alcohol intake, lifestyle factors, and details about each headache. We constructed within-person fixed-effect models adjusted for time-varying factors to calculate odds ratios for the association between 1,2,3,4, or 5+ servings of alcohol and headache the following day. We also calculated the adjusted risk of headache the following day for each level of intake. Among 98 participants who reported 825 headaches over 4,467 days, there was a statistically significant linear association (p-trend =0.03) between alcohol and headache the following day. Compared to no alcohol, 1-2 servings were not associated with headaches, but 5+ servings were associated with a 2.08-fold (95% confidence interval [CI] 1.16-3.73) odds of headache. The adjusted absolute risk of headaches was 20% (95%CI 19%-22%) on days following no alcohol compared with 33% (95%CI 22%-44%) on days following 5+ servings. 1-2 servings of alcoholic beverages were not associated with higher risk of headaches the following day, but 5+ servings were associated with higher risk. Key Messages:1-2 servings of alcoholic beverages were not associated with a higher risk of headaches on the following day, but higher levels of intake may be associated with higher risk.Five or more servings were associated with 2.08 times (95% confidence interval 1.16-3.73 the odds of headache on the following day.The adjusted absolute risk of headaches was 20% (95%CI 19%-22%) on days following no alcohol consumption compared with 33% (95% CI 22%-44%) on days following 5+ servings.
