Randomized Controlled Trial
Thermal Versus Super Voltage Pulsed Radiofrequency of Stellate Ganglion in Post-Mastectomy Neuropathic Pain Syndrome: A Prospective Randomized Trial.
Breast cancer is the second most common cancer world-wide following lung cancer. Post-mastectomy pain syndrome (PMPS) is one of the chronic post-surgical pain disorders (CPSP) of neuropathic character; nearly 20-50% of patients may develop PMPS. Stellate ganglion blockade has been performed as a diagnostic, prognostic, or therapeutic intervention for different pain syndromes. ⋯ Cancer breast, post mastectomy pain syndrome, stellate ganglion block, radiofrequency therapy.

Dorsal root ganglion stimulation (DRGS) treats discrete, localized areas of neuropathic pain. But there are no long-term results available so far. ⋯ Knee pain, foot pain, hand pain, groin pain, neuromodulation, dorsal root ganglion stimulation, chronic neuropathic pain, paresthesia mapping.

Randomized Controlled Trial
Evaluation of an Experimental Pain Model by Noncompartmental Analysis of Results from a Randomized Placebo Controlled Trial.
Understanding analgesic pharmacodynamics (PD) in the elderly is key to optimising pain management. Electrically stimulated pain models (ESPM) permit assessment of pain responses in humans. C and A-delta sensory fibres convey pain and respond to low frequency electrical stimulus (5 and 250 Hz, respectively). Human research suggests pain tolerance threshold (PTT) is similar or decreases with age. ⋯ Electrical pain model, elderly, geriatric, tramadol, placebo, opioid, area under the effect curve, noncompartmental analysis.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and chronic complication associated with cancer treatment. Prior investigations have demonstrated the presence of subclinical peripheral neuropathy in patients with colorectal cancer even before the patients had received chemotherapy. ⋯ Peripheral neuropathy, head and neck cancer, quantitative sensory testing.

Although sacroiliac joint dysfunction (SIJD) is generally regarded as a source of lumbar pain, its anatomical position and the absence of a diagnostic 'gold standard' lead to difficulties at examination and differential diagnosis. However, since sacroiliac (SI) joint blocks only provide information about pathologies of joint origin and since SIJD developing secondary to pathologies in structures around the joint can be missed. Provocation and palpation tests also need to be used in diagnosis. ⋯ Dysfunction, lumbar, sacroiliac joint, provocation test, sacroiliac joint pain, pain pattern.
