A laboratory at an off-campus Medical School office building. Eighty-four postmenarchal girls (43 No Pain, 41 Chronic Pain) ages 10-17 participated in the study. All participants completed self-report questionnaires assessing menstrual pain, pain catastrophizing, and anxiety sensitivity and completed a cold pressor task. Pain intensity during the task was rated on a 0 (no pain) to 10 (worst pain possible) numeric rating scale. After controlling for age, average menstrual pain ratings (without medication) were significantly correlated with cold pressor pain intensity for the No Pain group only. In the Chronic Pain group, menstrual pain ratings were significantly correlated with pain catastrophizing and anxiety sens...

To assess the association between responses to cold and pressure pain tasks in 133 nonclinical mothers and children (mean age 13.0 years; 70 girls), and the moderating effects of child sex and pubertal status on these mother-child relationships. Mothers and children independently completed the cold and pressure pain tasks. Multiple linear regression analyses examined the association between mothers' and children's laboratory pain responses. The moderating effects of child sex and pubertal status were tested in the linear models by examining the interaction among mother laboratory pain responses, and child sex and pubertal status. Mothers' cold pain anticipatory anxiety and pressure pain intensity were associated with children's pressure pain anticipatory anxiety. Mothers' pressure pain tolerance was a...

Substance use history was classified as screening positive for current illicit drug use (N=253), past drug use (N=617), and non-user (N=1,397) at baseline. To control for demographic correlates, age, sex and socioeconomic status (SES) were included as predictors. Covariance structure models indicated greater pain at baseline among participants acknowledging current substance use. Pain at baseline was also directly predicted by greater HIV/AIDS illness burden, lower SES, and older age. At 6 months, pain was directly predicted by prior pain, worse concurrent HIV/AIDS illness burden and female sex. At 12 months, pain was predicted by older age, prior pain, and concurrent HIV/AIDS illness. It was also modestly but significantly predicted by current substance use at baseli...

We also investigated risk factors for developing new cases of anxiety and depression. Analyses were conducted using multiple logistic regressions to control for key demographic and clinical factors. Our results showed a general stability of these psychiatric conditions across 6 months, with no dramatic increase in new cases. Overall prevalence declined over time, but a subgroup of patients, particularly those with major depression, evidenced persistent psychopathology. Having a high baseline HIV symptom count and a growing number of HIV symptoms significantly increased the likelihood of anxiety and depression persisting to follow-up and of developing new such cases. Our findings indicate that living with HIV does not necessarily lead to increased psychiatric distress but that palliation of HIV sympto...

Using sequential multiple regression, pain symptom scores, sex, and their interaction were analyzed in relation to nurse visits prospectively collected for 1 year. Neither sex, nor pain scores alone, predicted total nurse visits. For girls only, higher pain symptom scores predicted increased total visits and increased visits for complaints with documented physical findings. For both sexes, higher pain symptom scores predicted more visits for complaints without documented physical findings. A complex relationship between sex, pain-related symptoms, and self-initiated nurse visits was found in this pre-adolescent sample. Our findings suggest pain-focused symptom measures may be useful in studies of early predictors of adult pain-related healthcare utilization.

This study examined sex differences in anxiety sensitivity across unselected samples of 187 children with chronic pain (71.7% girls; mean age = 14.5) and 202 non-clinical children (52% girls; mean age = 13.6). Girls in the chronic pain and non-clinical samples reported elevated anxiety sensitivity relative to boys irrespective of clinical status. Girls with chronic pain also reported heightened fears of the physical consequences of anxiety compared to non-clinical girls but there were no such differences for psychological or social concerns. Among boys, anxiety sensitivity did not differ between the chronic pain and non-clinical groups. Future longitudinal research may examine whether specific fears of anxiety-related somatic sensations constitutes a sex-based vulnerability ...

The aim of this study is to examine the relationship between sex and pubertal differences in autonomic arousal and pain tolerance to laboratory pain stimuli in healthy children. We tested the following specific hypotheses: (1) females would have greater autonomic arousal and less pain tolerance than males, and (2) this sex difference in pain tolerance would be mediated by autonomic arousal. Participants were 244 healthy children (50.8% female, mean age 12.73+/-2.98 years, range 8-18 years). Separate 4-trial blocks of cutaneous pressure and thermal pain stimuli were presented in counterbalanced order. Heart rate (HR) was recorded during 2-3 min periods preceding each block and a 1-min period between trials. Results indicated lower tolerance in females for cutaneous pressure, but not thermal pain, compared to males. In addition, pre-trial HR was greater for females than males. Mediation analyses suggested that sex differences in pressure pain tolerance were accounted for by sex differences in pre-trial HR. There were also significant effects for puberty, but these did not vary by sex. Overall, early pubertal children had greater pre-trial HR and less pain tolerance than those in late puberty for both cutaneous pressure and thermal pain across sex. These results suggest that autonomic arousal may be a mediator of sex-related differences in pain responses in children.

This lack of social support network impairs social coping skills and can lead to worsening pain symptoms. In this case study, we describe a new program to disrupt the cycle of social isolation and chronic pain by emphasizing social coping skills via peer mentorship. The program aimed to utilize peers who have learned to self-manage their own chronic pain to assist patients with social coping skills to reduce isolation caused by chronic pain conditions. Children and adolescents with chronic pain. This case describes the experience of a 17 year-old, African American boy with diffuse chronic body pain as a participant ("the mentee") in the program; his mentor was a 19 year-old girl with chronic pain associated with rheumatoid arthritis. The mentor...

Symptoms include discomfort in the abdomen, along with diarrhea and/or constipation and other gastroenterological symptoms that can significantly impact quality of life and daily functioning. Emotional stress appears to exacerbate irritable bowel syndrome symptoms suggesting that mind-body interventions reducing arousal may prove beneficial. For many sufferers, symptoms can be traced to childhood and adolescence, making the early manifestation of irritable bowel syndrome important to understand. The current study will focus on young people aged 14-26 years with irritable bowel syndrome. The study will test the potential benefits of Iyengar yoga on clinical symptoms, psychospiritual functioning and visceral sensitivity. Yoga is thought to bring physical, psychological and spiritual benefits to practitioners and has been associated with reduced stress and pain. Through its focus on restoration and use of props, Iyengar yoga is especially designed to decrease arousal and promote psychospiritual resources in physically compromised individuals. An extensive and standardized teacher-training program support Iyengar yoga's reliability and safety. It is hypothesized that yoga will be feasible with less than 20% attrition; and the yoga group will demonstrate significantly improved outcomes compared to controls, with physiological and psychospiritual mechanisms contributing to improvements. Methods/Design: Sixty irritable bowel syndrome patients aged 14-26 will be randomly assigned to a standardized 6-week twice weekly Iyengar yoga group-based program or a wait-list usual care control group. The groups will be compared on the primary clinical outcomes of irritable bowel syndrome symptoms, quality of life and global improvement at post-treatment and 2-month follow-up. Secondary outcomes will include visceral pain sensitivity assessed with a standardized laboratory task (water load task), functional disability and psychospiritual variables including catastrophizing, self-efficacy, mood, acceptance and mindfulness. Mechanisms of action involved in the proposed beneficial effects of yoga upon clinical outcomes will be explored, and include the mediating effects of visceral sensitivity, increased psychospiritual resources, regulated autonomic nervous system responses and regulated hormonal stress response assessed via salivary cortisol.

In this project, we will compare a standardized Iyengar yoga program for young people with rheumatoid arthritis to a standard care wait-list control condition. Methods/Design: Seventy rheumatoid arthritis patients aged 16-35 years will be randomized into either the 6-week Iyengar yoga program (12 -1.5 hour sessions twice weekly) or the 6-week wait-list control condition. A 20% attrition rate is anticipated. The wait-list group will receive the yoga program following completion of the first arm of the study. We will collect data quantitatively, using questionnaires and markers of disease activity, and qualitatively using semi-structured interviews. Assessments include standardized measures of general and arthritisspecific function, pain, mood, and health-related quality of life, as well as qualitative interviews, blood pressure/ resting heart rate measurements, a medical exam and the assessment of pro-inflammatory cytokines. Data will be collected three times: before treatment, post-treatment, and two months following the treatment. Discussion: Results from this study will provide critical data on non-pharmacologic methods for enhancing function in rheumatoid arthritis patients. In particular, results will shed light on the feasibility and potential efficacy of a novel intervention for rheumatoid arthritis symptoms, paving the way for a larger clinical trial.

However, postevent psychological disorders may be underrecognized by primary care providers (PCPs). Rural PCPs in northern and central Florida were interviewed using a series of open-ended questions to assess knowledge of likely mental disorders, their risk factors, and preferred treatment options following such events (n=21). PTSD was identified by 14% and substance abuse by 10% of the sample. Physicians were significantly more likely to identify posttraumatic stress disorder (PTSD) as an expected postevent psychological disorder than nonphysician providers. PCPs were significantly more likely to endorse counseling (86%) than medications (43%) as a preferred treatment option. Our findings support the need for increased education and training regarding the mental health consequences of bioterrorism in rural PCPs, particularly for nursing-level and other nonphysician providers. Improvements in knowledge may enhance preparedness for such emergencies.

NP is a non-REM event that is distinct from sleep terrors, sleep apnea, nightmares or dream-induced arousals. This review outlines recent advances in the characterization of NP, as well as current approaches to the assessment and treatment of NP. In contrast to earlier work, more recent studies suggest that patients with NP do not differ from patients without NP on sleep architecture, sleep physiology, self-reported sleep quality and severity of panic disorder. However, more precise measurement of physiological precipitants and features is warranted. Assessment of NP focuses on ruling out other explanations for NP, with differential diagnosis based on interviews, sleep polysomnography and ambulatory recording of sleep. Psychological treatment (cognitive-behavioral therapy) targets misappraisals of anxiety sensations, hyperventilatory response, and conditioned reactions to internal, physical cues. Recent evidence supports the efficacy of this approach, however, controlled studies on pharmacological agents in the treatment of NP are lacking. Research is needed to examine the effects of combined cognitive-behavioral therapy and medications, compared to medication alone in the treatment of NP.

Yet, no large-scale studies have examined the experience of pain and its treatment in women living with HIV. This study used structural equation modeling to examine sex differences in pain and the use and misuse of prescription analgesics in a representative sample of HIV+ persons in the United Stated within a prospective, longitudinal design. Bodily pain subscale of the Short-Form 36 and Modified Short Form of the World Health Organization&amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Composite International Diagnostic Interview (opioid misuse). Women reported more pain than men over a roughly 6-month period regardless of mode of HIV transmission or prior drug use history. Men acknowledged more misuse of prescription analgesics over an approximate 1-year period compared with women, after taking into account pain, use of analgesics specifically for pain, and drug use history. Weaker associations between pain and use of analgesics specifically for pain that persisted over time were found among women compared with men. For both men and women, pain was stable over time. Problem drug use history exerted significant direct and indirect effects on pain, opioid misuse, and pain-specific analgesic use across sex. The current findings are consistent with prior evidence indicating female pain predominance as well as the undertreatment of pain among women with HIV. Efforts should be made to improve the assessment and long-term management of pain in HIV+ persons.

We therefore examined the relationships among panic disorder, posttraumatic stress disorder (PTSD), major depression and pain in a US national sample of persons with HIV, controlling for key sociodemographic and clinical variables, including HIV disease status. The study sample comprised 1489 HIV+ individuals (representing 219 667 persons). In multivariate analyses, panic disorder showed a strong association with pain ( beta= -15.70; 99% confidence interval [CI]=-21.33 to -10.08; P&amp;amp;amp;amp;amp;lt;0.001, which was significantly greater than PTSD (P=0.002) but only marginally greater than major depression (P=0.002). Longitudinal analyses of the three psychological disorders revealed that increasing pain from baseline to follow-up (an approximately 6-month period) was associated with panic disorder only (relative risk ratio=2.18, 99% CI=1.02-4.69; P&amp;amp;amp;amp;amp;lt;0.01), after controlling for baseline pain scores, baseline HIV disease status and change in disease stage across time. We discuss specific mechanisms by which clinical anxiety and chronic pain may be mutually maintained in HIV+ individuals. Our findings suggest that panic disorder, as well as PTSD and major depression are associated with greater pain in HIV patients.

The current study examined the psychometric properties of parent and child versions of a self-efficacy measure related to the child functioning normally when in pain. Pediatric pain patients, 9-18 years of age, and a caregiver completed questionnaires before an initial tertiary care clinic appointment. The 67 patients in our sample had an average of 1.7 pain locations, including abdominal pain (43.3%), headaches (50.7%), body pain (25.4%), back pain (23.9%), limb pain (20.9%), and/or chest pain (9.0%). Reliability for the new measures was excellent; the Cronbach's alpha was .89 for the 7 child items and .90 for the 7 parent items. Strong evidence for construct validity was also obtained as 23 of the 27 hypothesized correlations were confirmed. As predicted, parent and child ratings of increased self-efficacy for the child functioning normally when in pain were significantly correlated with each other, and to parent reports of fewer problems functioning due to physical or emotional problems; parent reports of fewer somatic, behavioral or emotional symptoms; parent reports of increased self-esteem, and unrelated to child pain, age and gender. Additionally, child ratings of increased self-efficacy were significantly correlated with child reports of increased selfesteem and fewer somatic symptoms. Replication with a larger sample size, more complex modeling, and prospective studies are indicated.

We examined the predictive and concurrent associations among pain, aberrant use of opioids, and problem drug use history in a nationally representative longitudinal sample of 2267 HIV+ persons. Covariance structure analyses tested a conceptual model wherein HIV+ patients with a history of problematic drug use (n=870), compared to those without such history (n=1397), were hypothesized to report more pain and aberrant opioid use, as well as use of opioids specifically for pain at baseline and 6- and 12-month follow-ups, after controlling for key sociodemographic characteristics. In support of the hypothesized model, patients with a history of problematic drug use reported more pain, and were more likely to report aberrant use of prescription analgesics, as well as use of such medications specifically for pain, compared to patients without such history. We also found a trend toward greater stability of aberrant opioid use over time in problem drug users compared with non-problem users suggesting a persistent pattern of inappropriate medication use in the former group. Our findings suggest that even though HIV+ persons with a history of problematic drug use report on-going patterns of using prescription analgesics specifically for pain, these patients continued to experience persistently higher levels of pain, relative to non-problem users. Among non-problem users, pain was not linked to aberrant use of opioids, but was linked to the use of such medications specifically for pain.

The study investigated pain prevalence in this population compared with sibling controls and examined painrelated risk factors. Three self-reported pain outcomes including pain conditions, prescription analgesics used, and pain attributed to cancer and treatment were assessed among 10,397 cancer survivors and 3,034 sibling controls from the Childhood Cancer Survivor Study (CCSS). Pain conditions (pain/abnormal sensation, migraines, and other headaches) were reported by 12.3%, 15.5%, and 20.5% of survivors respectively; 16.7% of survivors reported use of prescription analgesics, and 21% attributed pain to cancer and treatment. Risks of reporting pain conditions and using prescription analgesics were higher among survivors than siblings adjusting for sociodemographic factors. Younger age at diagnosis and a history of non-Hodgkin lymphoma, Wilms tumor, or neuroblastoma (compared to leukemia) were associated with greater risk of reporting pain conditions. A history of bone cancer or soft tissue sarcoma (compared to leukemia) was associated with greater risks of using prescription analgesics and cancer-related pain attribution. Non-brain directed scatter irradiation was associated with elevated risk for migraines and cancer-related pain attribution. Female gender and lower educational attainment were associated with increased reports of all three pain outcomes; minority status, unemployment, and being single were associated with greater risks for reporting pain conditions. These findings contribute to the understanding of pain and associated risk factors among adult survivors of childhood cancer and suggest areas of focus for pain intervention.

The complex associations among patient characteristics, pain, depression, and drug use in HIV suggests a role for testing models that can account for relationships simultaneously, control for HIV status and also test for mediation. Using structural equation modeling (SEM), the current study examined associations among pain, sociodemographics, illicit drug use and depressive symptoms in 921 HIV seropositive and 1,019 HIV seronegative men from the Multicenter AIDS Cohort Study (MACS), an ongoing prospective study of the natural history of HIV infection among gay/bisexual men. Longitudinal repeated measures data collected over a 6 year period were analyzed using predictive path models in which sociodemographics, HIV status and CD4+ cell counts predicted pain which in turn predicted depressive symptoms and illicit drug use. The path models did not differ substantially between HIV seropositive and seronegative men. Analyses using the total sample indicated that pain served both as a mediator and as a predictor of more use of cannabis, cocaine and heroin, as well as more depressive symptoms. HIV seropositive status predicted more use of inhaled nitrites. In this cohort, having lower CD4+ cell counts (predicted by HIV status), being African-American, less educated, and older were all associated with more pain which in turn was associated with more illicit drug use and more depressive symptoms. The results underscore the
