Altered gray matter volume in patients with herpes zoster and postherpetic neuralgia.
The aim of this study was to measure brain alterations in patients with herpes zoster (HZ) and postherpetic neuralgia (PHN) and compare their differences using a voxel-based morphometry (VBM) technique. ⋯ The VBM method revealed widespread GMV abnormalities in HZ and PHN patients. The brains of PHN patients have broader abnormalities in nonpain-related regions, suggesting the complexity of a central mechanism. When PHN patients were compared with HZ patients, the left cerebellar tonsil, culmen, and left lentiform nucleus corresponded to greater area under the curve, suggesting that abnormalities in these regions are risk factors for HZ patients' transformation to PHN.

Failed dural puncture during needle-through-needle combined spinal-epidural anesthesia: a case series.
Combined spinal-epidural (CSE) anesthesia is a widely used neuraxial anesthetic technique. In clinical practice, failed dural puncture during needle-through-needle technique occasionally occurs, with incidence of 5%-29%. We radiologically evaluated four cases of failed dural puncture during needle-through-needle CSE anesthesia. ⋯ Excessive paramedian deviation of the epidural needle may affect dural puncture during needle-through-needle CSE technique. Moreover, wrong passage of the spinal needle through Tuohy curve instead of the back hole, may contribute to failure of dural puncture.

Inhibition of electroacupuncture on nociceptive responses of dorsal horn neurons evoked by noxious colorectal distention in an intensity-dependent manner.
The transmission of visceral nociception can be inhibited by electroacupuncture (EA) at the spinal level. However, relationships between current intensity and EA-induced analgesia are still lacking. This study compares the effects of different intensities of EA at local acupoints and heterotopic acupoints on nociceptive responses of spinal wide dynamic range (WDR) neurons induced by noxious colorectal distension (CRD). ⋯ Within a certain range, the nociceptive responses of dorsal horn neurons induced by CRD could be inhibited by EA in an intensity-dependent manner.

Effect Of Peppermint Essence On The Pain And Anxiety Caused By Intravenous Catheterization In Cardiac Patients: A Randomized Controlled Trial.
The effects of the peppermint essence on the pain and anxiety caused by intravenous catheterization have not been studied yet. The aim of this study was to determine effect of inhaling peppermint essence on the pain and anxiety. ⋯ Aromatherapy attenuated the pain and anxiety caused by intravenous catheterization. Before catheterization, peppermint essence aromatherapy is recommended.

Pain experiences and intrapersonal change among patients with chronic non-cancer pain after using a pain diary: a mixed-methods study.
Pain diaries are a valuable self-assessment tool; however, their use in chronic non-cancer pain has received limited attention. In this study, we examined the effect of pain diary use on pain intensity, interference, and intrapersonal change in patients with chronic non-cancer pain. ⋯ Use of a pain diary in patients with chronic non-cancer pain was associated with reduced pain intensity and improved mood as well as function. Further controlled trials examining the long-term effects of pain diaries are warranted.
