Pregnancy is known to aggravate pre-existing chronic painful conditions. Trigeminal neuralgia (TN), albeit a disease of the elderly, may afflict pregnant females, which can further complicate its management. ⋯ This rare coexistence of TN in pregnancy has not been reported before. Here we present a case of TN in a young woman, whose pain was aggravated when she became pregnant, and she was treated successfully by conventional radiofrequency ablation of the Gasserian ganglion.

Randomized Controlled Trial
Increased sympathetic outflow induces adaptation to acute experimental pain.
There are interrelationships between the autonomic nervous system and pain. This study aims to explore the effect of different autonomic manipulations on pain perception and modulation. ⋯ Different effects of acute autonomic manipulations on experimental pain were found: an increase in sympathetic tone induced by yohimbine led to reduced pain sensitivity; a decrease in sympathetic tone with no effect on vagal-parasympathetic tone induced by phenylephrine led to reduction in pain adaptation capacity; and a decrease in sympathetic tone and increase in vagal parasympathetic tone by clonidine led to no change in pain adaptation capacity. While increased sympathetic outflow does facilitate pain adaptation, activation of either the sympathetic or parasympathetic limbs of the autonomic nervous system does not affect pain thresholds or CPM. Finally, a correlation exists between nociception and cardiovascular parameters only due to baroreflex activation.

Case Reports Clinical Trial
Radial Extracorporeal Shock Wave Therapy for Relief of Arthralgia in Rheumatoid Arthritis.
More than one-third of the population with rheumatoid arthritis requires adjuvant analgesic treatment after antirheumatic therapy. In addition to analgesics, another option is radial extracorporeal shock wave therapy (rESWT), a novel physical therapy that has been successfully used in the treatment of many types of chronic soft tissue pain. We report a series of 15 patients who suffered from arthralgia after being on disease-modifying antirheumatic drugs for more than 3 months. ⋯ By the end of treatment, 11 participants stopped analgesics completely; the other 4 participants were on a smaller dosage. No severe adverse effects related to rESWT were observed. To our knowledge, this is the first report using this therapy to treat arthralgia in rheumatoid arthritis.

Randomized Controlled Trial
The Effect of Intraoperative Systemic Lidocaine on Postoperative Persistent Pain Using IMMPACT Criteria Assessment Following Breast Cancer Surgery: A Randomized, Double-blind Placebo Controlled Trial.
To compare the incidence in postsurgical persistent pain following breast cancer surgery in women receiving intravenous lidocaine compared to saline using validated pain instruments in accordance with the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) recommendations. ⋯ Perioperative infusion of lidocaine has been reported to decrease the incidence of postsurgical pain at 3 and 6 months following mastectomy using dichotomous (yes/no) scoring. Although intravenous lidocaine reduced the reported incidence of pain at rest at 6 months, pain with activity, pain qualities, and the physical or emotional impact of the pain were unaffected. Future studies evaluating postsurgical persistent pain should adhere to the IMMPACT recommendations in order to more accurately describe the effect of an intervention on persistent pain.

Inadequately treated postoperative pain can lead to longer healing processes, longer hospital stays, and the development of chronic pain. In a 900-bed university hospital in Switzerland, pain scores were assessed systematically. The study's primary aim was to define whether the routine pain assessment on the ward is accurate and reproducible. Subsequently the obtained data were used for a benchmark analysis to determine the hospital's performance in pain assessment quality compared with similar centers. ⋯ The cross-sectional data comparison of pain assessment by the ward staff and by interviews with the PAIN OUT questionnaire showed a large gap of underrated pain. The benchmark analysis with the method of PAIN OUT suggests a decent pain management among reference groups.
