Aim To investigate the impact of pain intensity of postherpetic neuralgia (PHN) patients. Methods This cross sectional study included 30 PHN patients attended to the Dermatology and Venereology Department of the School of Medicine of Universitas Sumatera Utara during the period between April 2019 and October 2019. Zoster Brief Pain Inventory questionnaire including the worst pain in 24 hours and the level of interference with seven domains of quality of life (QoL) (general activity, mood, walking ability, working, relationship with other people, sleep and enjoyment of life) were used. ⋯ Therefore, the correlation between worst pain intensity and walking ability was moderate (r=0.475). The worst pain intensity had a significant correlation with all seven domains of QoL (p<0.05). Conclusion Pain intensity influences the QoL with directly proportional correlation between pain intensity and disturbance of QoL.

Temporary, percutaneous peripheral nerve stimulation (PNS) has been shown to provide analgesia for acute postoperative pain, postamputation pain, and low back pain. The implanted device stimulates the neural target for up to 60 days at which point the leads are extracted. Patients have demonstrated prolonged analgesia continuing after extraction of the leads. The purpose of this case series is to demonstrate peripheral neural targets that could feasibly be used to treat various pain syndromes prevalent in the oncologic population. ⋯ PNS has potential uses in the treatment of oncologic pain. Further high-quality studies should be designed to further elucidate use of the PNS to treat oncologic pain.

ReviewRegional Hyperexcitability and Chronic Neuropathic Pain Following Spinal Cord Injury.
Spinal cord injury (SCI) causes maladaptive changes to nociceptive synaptic circuits within the injured spinal cord. Changes also occur at remote regions including the brain stem, limbic system, cortex, and dorsal root ganglia. These maladaptive nociceptive synaptic circuits frequently cause neuronal hyperexcitability in the entire nervous system and enhance nociceptive transmission, resulting in chronic central neuropathic pain following SCI. ⋯ Current literature describes regional studies of electrophysiological or neurochemical mechanisms for enhanced nociceptive transmission post-SCI, but few studies report the electrophysiological, neurochemical, and neuroanatomical changes across the entire nervous system following a regional SCI. We, along with others, have continuously described the enhanced nociceptive transmission in the spinal dorsal horn, brain stem, thalamus, and cortex in SCI-induced chronic central neuropathic pain condition, respectively. Thus, this review summarizes the current understanding of SCI-induced neuronal hyperexcitability and maladaptive nociceptive transmission in the entire nervous system that contributes to chronic central neuropathic pain.

Peripheral neuralgia is a common cause of chronic pain. Treatment might be challenging, and the condition can be resistant to commonly used treatment modalities for chronic pain. We present five cases of peripheral neuralgia who were successfully treated using wireless peripheral nerve stimulation. ⋯ We present five patients with peripheral neuralgias resistant to other treatment modalities who received excellent pain relief following implantation of a peripheral nerve stimulator.
