In recent decades, there has been a revision of the role of institutional review boards with the intention of protecting human subjects from harm and exploitation in research. Informed consent aims to protect the subject by explaining all of the benefits and risks associated with a specific research project. To date, there has not been a review published analyzing issues of informed consent in research in the field of genetic/Omics in subjects with chronic pain, and the current review aims to fill that gap in the ethical aspects of such investigation. ⋯ We see this contribution as an important one, for while ethical issues are too often ignored in pain research in general, the numerous arising ethical issues that are unique to pain genetic/Omics suggest that researchers in the field need to pay even greater attention to the rights of subjects/patients. This article presents the work of the Ethic Committee of the Pain-Omics Group (www.painomics.eu), a consortium of 11 centers that is running the Pain-Omics project funded by the European Community in the 7th Framework Program theme (HEALTH.2013.2.2.1-5-Understanding and controlling pain). The Ethic Committee is composed of 1 member of each group of the consortium as well as key opinion leaders in the field of ethics and pain more generally.

The "Douleur Neuropathique 4 (DN4) questionnaire" was developed for screening neuropathic pain. The purpose of this work was to validate the DN4 questionnaire in the standard Arabic language. First, the questionnaire was translated and semantically adapted to Arabic according to the international guidelines for cross-cultural adaptation. ⋯ The sensitivity and specificity of the 7-item DN4 and 10-item DN4 were not influenced by either pain severity or educational level. In conclusion, this new Arabic version DN4 questionnaire is a simple, reliable, and valid tool for discriminating between neuropathic and non-neuropathic pain. It represents a useful tool in clinical setting and population-based studies.

Parental behavior plays a significant role in children's pain response. Prior research has found generally no differences between mothers' and fathers' verbal behavior during child pain. This study compared mothers' and fathers' nonverbal behavior during child pain. ⋯ However, children of mothers who engaged in more physical comfort/reassurance reported higher levels of pain intensity, and children of mothers who engaged in more procedure-related attending behaviors had lower pain tolerance. Further, both mothers and fathers who engaged in higher levels of verbal nonattending behaviors also engaged in lower levels of nonverbal procedure-related attending behaviors. These findings further support the importance of considering the influence of mothers and fathers in children's pain, and provide novel insights into the role of nonverbal behavior.

Chronic pain is significantly influenced by behavioral, cognitive, and emotional factors. Few studies have investigated the health locus of control (HLC)-one's belief regarding where control over one's health lies-as it relates to patients with chronic pain. The purpose of this prospective, cross-sectional study was to examine the relationship between depression and health/pain locus of control (HLC) in adult patients with persistent pain. ⋯ The study shows that patients with an internal locus of control are less depressed compared to patients with fatalistic views on their health/pain in the chance group. The chance dimension of the Multidimensional Health Locus of Control scale was found to be a potential predictor of psychiatric comorbidities such as depression in the chronic pain patient population.

This study investigated the prevalence, etiology, assessment, treatment of pain in patients with cancer as well as their quality of life (QOL). ⋯ This study revealed the prevalence of neuropathic cancer pain in Chinese patients with cancer. Malignant neuropathic pain significantly impaired the patients' QOL. Insufficient assessment and inadequate analgesia still exist. These require more awareness and attention from both doctors and patients.
