To study the associations of sociodemographic factors, working conditions, lifestyle and previous pain in the spine with new onset chronic neck pain (NP). ⋯ We found potentially modifiable predictors of chronic NP among employees: workplace bullying, sleep problems, and high body mass index in women, and work-related emotional exhaustion in men. In both genders, previous acute NP and chronic LBP were predictive of chronic NP.

Previous studies suggest that pain management by analgesic medications may be low among children. This study aims to investigate analgesic use and its correlates among children in Germany. ⋯ Analgesic use appears to be low among children in Germany, reflecting largely the fact that pain perceived among children under ambulant care may be mild to moderate and does not need analgesic medications. As the majority of paediatric analgesics were self-medicated, use of analgesics still should be closely monitored particularly among specific subpopulations such as adolescents to avoid potential abuse.

Randomized Controlled Trial
Attention focus, trait anxiety and pain perception in patients undergoing colposcopy.
Few studies have compared the relative efficacy of attention-focus strategies in reducing clinical pain. Colposcopy, a medical diagnostic examination performed to identify premalignant cervical cell changes, elicits both anxiety and pain in patients, while allowing little or no behavioural control over the event. Employing a multi-group experimental design, the present study sought to investigate how different types of attention-focus strategies impacted upon pain perception, state anxiety and affect, in a sample of 123 colposcopy patients. ⋯ Pre-colposcopy pain expectancy, but not trait anxiety, was found to be positively related to colposcopy-related pain. It was further demonstrated that heightened state anxiety following colposcopy was due to experienced pain and pain unpleasantness, rather than to aspects of the pre-colposcopy prediction of pain. The results have implications for management of acute clinical pain.

The incidence of chronic post-surgical pain (CPSP) after various common operations is 10% to 50%. Identification of patients at risk of developing chronic pain, and the management and prevention of CPSP remains inadequate. The aim of this study was to develop an easily applicable risk index for the detection of high-risk patients that takes into account the multifactorial aetiology of CPSP. ⋯ Five predictors multivariately contributed to the prediction of CPSP: capacity overload, preoperative pain in the operating field, other chronic preoperative pain, post-surgical acute pain and co-morbid stress symptoms. These results suggest that several easily assessable preoperative and perioperative patient characteristics can predict a patient's risk of developing CPSP. The risk index may help caregivers to tailor individual pain management and to assist high-risk patients with pain coping.

The effect of catechol-O-methyltransferase polymorphisms on pain is modified by depressive symptoms.
Variations within the catechol-O-methyltransferase (COMT) gene have been associated with pain severity in temporomandibular disorders (TMDs). Psychological factors such as personal conflicts, life stress and depression, are well known to be associated with onset, severity and chronicity of pain disorders. ⋯ Our results indicate that variants within the COMT gene are associated with pain perception. However, this association is highly moderated by the absence or presence of lifetime depressive symptoms.
