Long-term opioid therapy for chronic pain management requires regularly assessing and documenting benefits and side effects. Opioid-induced sex hormone disturbances are a complication that needs to be assessed routinely and perhaps not only when suspected. There is abundant literature about its prevalence, clinical consequences, and treatment, yet routine hormone screening and appropriate treatment are seldom performed in pain clinics. Ignorance, skepticism, and/or indifference are possible reasons explaining why opioid-induced hypogonadism (OIH) remains underdiagnosed among chronic pain patients. ⋯ Knowledge and attitudes towards OIH varied among this population of pain clinicians invited to participate in the research. Lack of knowledge and incertitude seem to impact the attitudes towards screening and treating OIH. Better medical training at undergraduate and postgraduate levels as well as continuous medical education may contribute to raising awareness about this complication and providing early treatment.

Randomized Controlled Trial Comparative Study
Comparison of Ultrasound-Guided Supraclavicular and Interscalene Brachial Plexus Blocks in Postoperative Pain Management After Arthroscopic Shoulder Surgery.
The interscalene brachial plexus block (ISBB) is an effective procedure for minimizing postoperative opioid consumption and pain following arthroscopic shoulder surgery. The ultrasound (US)-guided supraclavicular brachial plexus block (SCBB) seems to be an alternative technique for arthroscopic shoulder surgery. However, evidence is lacking regarding the impact of SCBB on postoperative pain management and recovery after arthroscopic shoulder surgery. The aim of this study was to compare the effects of SCBB with ISBB in terms of postoperative pain and quality of recovery after arthroscopic shoulder surgery. ⋯ This study showed that US-guided SCBB is as effective as ISBB in reducing postoperative pain and improving the quality of recovery for arthroscopic shoulder surgery.

Observational Study
Influence of the menstrual cycle phase on pain perception and analgesic requirements in young women undergoing gynecological laparoscopy.
The influence of the gonadal hormones on some aspects of the human physiology has been studied with uncertain results. Still a confusion exists in relation to the real effects of the female hormones on the perception of pain. The existing data refer mainly to experimental studies and have provided results not always useful in the clinical practice. ⋯ The results of this study have demonstrated that in postoperative female patients pain is perceived significantly more in the luteal phase of the menstrual period, than in the follicular phase. This could suggest that female in child-bearing age should be scheduled for elective surgery preferentially during the follicular phase, unless differently necessary. It would guarantee a more comfortable postoperative period, with reduced necessity of analgesics.

Observational Study
Prospective cohort analysis of DRG stimulation for failed back surgery syndrome pain following lumbar discectomy.
Surgical lumbar discectomy is a commonly performed routine spinal procedure that is usually undertaken to alleviate lumbar radicular symptoms caused by a herniated intervertebral disc. Surgical lumbar discectomy can also lead to chronic postsurgical leg and/or back pain (failed back surgery syndrome [FBSS]), a condition that can be refractory to conventional medical management. Early clinical results on the use of dorsal root ganglion (DRG) stimulation for FBSS have supported the use of this treatment alternative. ⋯ These results suggest that DRG stimulation induces pain relief in subjects diagnosed with FBSS. These reductions in pain were also associated with improvements in quality of life and disability. Additional prospective studies are warranted to further investigate this potential application of DRG stimulation, as well as to optimize patient selection, lead placement, and programming strategies.

Observational Study
Prediction of acute postoperative pain from assessment of pain associated with venous cannulation.
It has previously been reported that venous cannulation-induced pain (VCP) can be used to predict acute postoperative pain after laparoscopic cholecystectomy. Patients rating VCP at ≥2.0 VAS units had 3.4 times higher risk for moderate or severe pain. The purpose of this study was to evaluate if VCP scores of ≥2.0 VAS units are associated with higher risk for acute postoperative pain after various common surgical procedures. ⋯ Scoring of VCP intensity before surgery, requiring no specific equipment or training, is useful to predict individual risks for moderate or severe postoperative pain, regardless of patient age or gender, in a setting involving different kinds of surgery.
