Case Reports Clinical TrialEffects of Trigger Point Dry Needling on Neuromuscular Performance and Pain of Individuals Affected by Patellofemoral Pain: A Randomized Controlled Trial.
To investigate the effects of trigger point dry needling (TrP-DN) on exercise-induced patellofemoral pain syndrome (PFPS). ⋯ TrP-DN at the quadriceps combined with stretch can reduce the pain, and improves the clinical symptoms and function, the VMO/VL ratio, and the coordination of VMO and VL in patients with PFPS.

Chronic Pain Patients' Kinesiophobia and Catastrophizing are Associated with Activity Intensity at Different Times of the Day.
To examine the relationship between baseline kinesiophobia and baseline pain catastrophizing with the 4-day average activity intensity at different times of the day while accounting for different wake and sleep-onset times in chronic pain patients. ⋯ Baseline kinesiophobia and baseline catastrophizing were not associated with the 4-day average total daily activity; however, they were associated with 4-day average activity intensities at different times throughout the day. Segmenting daily activity into morning, afternoon, evening may influence the relationship between daily activity, and kinesiophobia and pain catastrophizing. Individuals with chronic pain are less sedentary than previously thought which may affect future interventions.

Role of Dopaminergic Receptors Within the Ventral Tegmental Area in Antinociception Induced by Chemical Stimulation of the Lateral Hypothalamus in an Animal Model of Orofacial Pain.
The ventral tegmental area (VTA), as one of the classical components of the brain reward circuitry, shares large neural networks with the pain processing system. We previously showed the role of VTA dopamine receptors in modulation of lateral hypothalamus (LH)-induced antinociception in acute pain conditions. However, considering the fact that the neural systems involved in the mediation of tonic pain are not the same as those that mediate phasic pain. In the present study, we aimed to examine the role of intra-VTA dopamine receptors in LH-induced antinociceptive responses during tonic orofacial pain conditions. ⋯ The findings suggest that chemical stimulation of the LH by carbachol possibly activates the orexin projecting neurons and subsequently, the VTA dopaminergic neurons involved in the orofacial pain modulation. Detecting such neural circuitry offers an alternative approach in the development of more efficient therapies for such debilitating pain conditions.

Knowledge and Attitude Towards Non-Pharmacological Pain Management and Associated Factors Among Nurses Working in Benishangul Gumuz Regional State Hospitals in Western Ethiopia, 2018.
Millions of people worldwide are suffering from pain. Non-pharmacological therapy has an important role in the treatment of pain and is recognized as a valuable, simple help to lower the dosage of analgesic drugs needed, decreasing the side effects, reducing drug dependency and reducing health care costs; however, knowledge and attitude of nurses greatly affect the use of non-pharmacological pain management methods. ⋯ Nurses in Benishangul Gumuz regional state hospitals have unfavorable attitude, but they have relatively adequate knowledge about non-pharmacological pain management. Work experience, level of education, nurse to patient ratio and taking educational courses were associated with nurses' knowledge, and nurse to patient ratio, training, and knowledge of non-pharmacological pain management were associated with nurses' attitude. Therefore, efforts should focus on innovative educational strategies for nurses, training and achieving a 1:6 nurse to patient ratio.

Case ReportsUltrasound-Guided Lumbar Intradiscal Injection for Discogenic Pain: Technical Innovation and Presentation of Two Cases.
We described two cases and the techniques for using the ultrasound (US) to guide lumbar intradiscal injection with platelet-rich plasma (PRP). The two cases suffered from chronic low back pain. Magnetic resonance imaging revealed posterior annular tear of the L5/S1 intervertebral disc (IVD) in the first case and L4/5 and L5/S1 IVDs in the second case. ⋯ At the follow-up, both patients had significant improvement after the intradiscal PRP injections (visual analogue scale from 7.5 to 1.5 on average). The report indicated US-guided lumbar intradiscal PRP injection to be a feasible approach for treatments of low back pain. Familiarization of the anatomy and sonoanatomy of the lumbar spine is fundamental to achieve the success of intradiscal injection.
