Multicenter Study Observational Study
Effectiveness and Safety of Intrathecal Ziconotide: Interim Analysis of the Patient Registry of Intrathecal Ziconotide Management (PRIZM).
The Patient Registry of Intrathecal Ziconotide Management (PRIZM) evaluated long-term effectiveness, safety, and tolerability of intrathecal ziconotide treatment in clinical practice. ⋯ Greater improvements in efficacy outcomes were observed when ziconotide was initiated as first-line intrathecal therapy vs. not first intrathecal agent in pump. The adverse event profile was consistent with the ziconotide prescribing information.

Good adherence to prescribed analgesics can be crucial to suppress or even prevent acute postoperative pain after day surgery. The aim of this study was to analyze prevalence and predictors of analgesic nonadherence after day surgery. ⋯ Analgesic nonadherence and partial adherence are common after day surgery but decrease as average pain intensity increases. Patients at risk for analgesic nonadherence can be identified during the preoperative period based on preoperative pain intensity, preoperative expectations of pain, and fear of surgery.

Case Reports
Four Extremity Neurostimulation Using Two Cervical octapolar leads and high-frequency of 10-kHz.
A few published reports describe successful clinical use of low-frequency spinal cord stimulation (SCS) in the cervical spine resulting in bilateral upper and lower extremity pain relief. A major side-effect when using this modality of SCS is the uneven intensity of paresthesias, which are frequently excessive in upper extremities while attempting to achieve optimal paresthesia coverage in all 4 extremities. ⋯ Here we describe a successful case of high-frequency SCS at 10 kHz where profound control of neuropathic pain of all 4 extremities was achieved without the complication of paresthesias. Discussed are future implications of such therapy.

Central sensitization (CS) implies increased sensitivity of the nervous system, resulting in increased pain sensitivity as well as widespread pain. Recently, the Central Sensitization Inventory (CSI) was developed to assess symptoms of CS and central sensitivity syndromes. The aim of this study was to examine the convergent validity of the CSI by comparing the outcome to psychosocial factors and clinical features of CS. ⋯ In this study, the convergent validity of the CSI was measured with demonstration of a strong relationship between contributing factors and clinical features of CS. These findings of convergent validity, considering former studies of the CSI, underline the use of the questionnaire in the clinical practice.

The aim of the study was to define risk factors related to pain in adult end-stage renal disease (ESRD) patients on chronic intermittent hemodialysis (HD) by developing a systematic review of published data. ⋯ Multiple factors for various types of pain in very heterogeneous populations and heterogeneous settings were analyzed in the literature. The results turned out to be inconsistent between the studies. Future large-scale studies are required, taking into the account limitations of the current evidence base.
