A cohort of patients with sickle cell disease, consisting of children, adolescents, and adults, who reported experiencing three or more episodes of vaso-occlusive pain the preceding year, were enrolled in a prospective two-period treatment protocol. Following a 4-month conventional treatment baseline phase, a supplemental cognitive-behavioral pain management program that centered on self-hypnosis was implemented over the next 18 months. Frequency of self-hypnosis group straining sessions began at once per week for the first 6 months, became biweekly for the next 6 months, and finally occurred once every third week for the remaining 6 months. Results indicate that the self-hypnosis intervention was associated with a significant reduction in pain days. Both the proportion of "bad sleep" nights and the use of pain medications also decreased significantly during the self-hypnosis treatment phase. However, participants continued to report disturbed sleep and to require medications on those days during which they did experience pain. Findings further suggest that the overall reduction in pain frequency was due to the elimination of less severe episodes of pain. Non-specific factors may have contributed to the efficacy of treatment. Nevertheless, the program clearly demonstrates that an adjunctive behavioral treatment for sickle cell pain, involving patient self-management and regular contact with a medical self-hypnosis team, can be beneficial in reducing recurrent, unpredictable episodes of pain in a patient population for whom few safe, cost-effective medical alternatives exist.

The purposes of this report are: (1) to investigate the association between sleep disturbances and depressive symptomatology in older adults; (2) to evaluate the degree to which gender serves to mediate this relationship; and (3) to determine whether several predefined covariates help to explain the association between sleep disturbance and depressive symptoms. This is a retrospective and cross-sectional analysis of baseline data from 485 elderly adults enrolled in three of the eight clinical sites participating in the Frailty and Injuries: Cooperative Studies of Intervention Techniques (FICSIT) trials. FICSIT was a linked series of randomized clinical trials which evaluated the impact of various exercise interventions on several measures of frailty in older adults. Women reported more depressive symptoms and more sleep disturbances than men. Sleep disturbances were independently associated with depressive symptoms, bodily pain, a history of falling, limited education, being married, and being female. Gender interactions suggest that, although women reported more depressive symptoms and more chronic health conditions than men, both may be more important predictors of sleep disturbance in men. By contrast, being married may be more predictive in women. Finally, the data suggest a stronger relationship between sleep disturbance and depressive symptoms in men than in women.

Dentistry uses a variety of different polymer materials. Dental polymer materials are based on methacrylate, its polymer, and polyelectrolytes. The setting of restorative materials and adhesives is initiated chemically by mixing two components or by light. In both cases, polymerisation is incomplete and monomers, not reacted, release. Studies have documented that monomers may cause a wide range of adverse health effects such as irritation to skin, eyes or mucous membranes, allergic dermatitis, asthma, parenthesise in the fingers, and disturbances from central nervous system such as; headache, pain in the extremities, nausea, loss of appetite, fatigue, sleep disturbances, irritability, loss of memory and changes in blood parameters. Dental personnel are occupationally exposed when handling the non reacted monomers. The use of gloves do not give enough protection as monomers, released from the material, easily penetrate all gloves used in dentistry. Face masks do not prevent inhalation of monomers. Ordinary glasses do not protect the eyes against vapor from monomers. The result from this study demonstrate the need for the development of ergonomic procedures and practices for safe handling of such materials in dental clinics.

Sleep complaints are frequent in patients with rheumatoid arthritis (RA) and sleep disturbances may contribute to pain and other daytime complaints. The aims of the current study were to compare ambulatory sleep recordings from consecutively selected patients with RA to those obtained in healthy controls, and to study the relationships between sleep structure and clinical symptoms. Sleep recordings were obtained from 41 out-patients with RA and 19 matched controls. All had clinical examinations and completed different questionnaires. Recordings were scored traditionally and, moreover, the electroencephalography (EEG) was subjected to frequency analysis. For the study of sleep-wake interactions in the patients, a graphical chain model was used. The patients had many sleep-related complaints. An increase in the number of periodic movements of the legs (PML) during sleep was seen in comparison with controls, but otherwise only minor differences were observed in classical sleep stages. Data from frequency analysis showed an increase in alpha (8-12 Hz)-EEG activity in sleep stages non-rapid eye movement (NREM) 2-4 in most sleep cycles. The statistical model demonstrated a complex but independent correlation between morning stiffness, pain and joint tenderness on the one hand, and awakenings, stage NREM2, slow-wave sleep and stage REM on the other, probably reflecting a relationship between sleep patterns and pain in RA. In conclusion, only the increase in PML and alpha-EEG activity distinguished the sleep in RA patients from that of healthy controls. However, the demonstrated interaction between daytime complaints and sleep patterns may increase the understanding and treatment of the disease. In future research, graphical chain models may improve our understanding of complex relationships between multiple variables.

This study was conducted to compare the analgesic action of Lysine Clonixinate (LC) vs Paracetamol/Codeine association (PC) in the treatment of postepisiotomy pain in primiparae women: 131 primiparous patients with moderate-to-severe postepisiotomy pain were enrolled in a double blind dummy design study and randomly allocated to either treatment with fixed doses of LC 125 mg or Paracetamol 500 mg+Codeine 30 mg 6 qh during 24 hours. Intensity of spontaneous pain and pain on walking was assessed according to a visual analog scale (VAS) and patient's assessment before receiving treatment and after 1, 2, 6 and 24 hours. Intensity of spontaneous pain was reduced in 24 hours from 4.28 +/- 2.11 to 1.73 +/- 1.46 (P < 0.0001) in the LC group and from 4.78 +/- 2.08 to 1.90 +/- 1.72 in the PC-treated group (p < 0.0001); with no significant differences between treatments. 54% of the patients treated with LC and 55% of those receiving PC showed onset of analgesic action 30 minutes following dose administration. Patient's final global assessment revealed that 95% of LC-treated patients and 96% of the PC group showed total or partial pain relief during the first treatment day. No sleep disturbances were seen during the night in 75% of patients. Only one patient receiving LC showed nausea not requiring treatment discontinuation. It is concluded that both treatments are equally effective to relieve moderate-to-severe postepisiotomy pain.

Pain and discomfort in everyday life are often treated with over-the-counter (OTC) analgesic medications. These drugs are remarkably safe, but serious side effects can occur. Up to 70% of the population in Western countries uses analgesics regularly, primarily for headaches, other specific pains and febrile illness. It is not known whether the patterns of use are consistent with good pain management practices. OTC analgesics are also widely used to treat dysphoric mood states and sleep disturbances, and high levels of OTC analgesic medication use are associated with psychiatric illness, particularly depressive symptoms, and the use of alcohol, nicotine and caffeine. More than 4 g per day of acetylsalicylic acid (ASA) or acetaminophen over long periods is considered abuse. People using excessive amounts of OTC analgesics may need more effective treatments for chronic pain, depression or dysthymia. The possibility that these drugs have subtle reinforcing properties needs to be investigated. Certainly phenacetin, which was taken off the market in the 1970s, had intoxicating effects. A better understanding of patterns of use is needed to determine the extent of problem use of OTC analgesics, and whether health could be improved by educating people about the appropriate use of these drugs.

Fatigue is a common and troubling symptom in patients with cancer or HIV/AIDS, resulting in significant disability and adverse effects on quality of life. Its etiology remains complex and is most likely multifactorial. Despite its impact and prevalence, fatigue is often overlooked and undertreated in these patient populations. The general perceptions of fatigue are that its etiology cannot be determined, it is an inevitable manifestation that must be endured, and few interventions are available. Efforts are ongoing to better understand the etiology, characteristics, and consequences of fatigue in patients with cancer or HIV/AIDS. New practical methods of assessing it in cancer patients are now available. In order to improve the quality of life in these patients, physicians need to reassess their perceptions of fatigue and their approach to its diagnosis and management. There are recognizable causes and correlates for which interventions can be beneficial. These include anemia, pain, infection/fever, hormonal or nutritional deficiencies, depression/anxiety, sleep disturbances, and excessive inactivity or rest. Physicians should fully evaluate patients to identify the factors amenable to management. Fatigue is also seldom discussed by patients and their physicians. Improved communication with and counseling of patients and their caregivers can play an important role in the effective assessment and management of fatigue in patients with cancer or HIV/AIDS. Many patients may benefit from wider implementation of recent advances in the understanding and treatment of fatigue in these oncologic and infectious conditions.

The objective of this study was to assess outcomes of pediatric day surgery tonsillectomy. A total of 129 children, aged 5-16 years, and their parents were recruited from three urban hospitals which provided pediatric day surgery. Children reported pain on a visual analogue scale (VAS) in day surgery and then daily at home for 7 days. Parents reported outcomes of surgery, including fluid intake, nausea, vomiting and sleep disturbances. They also recorded analgesic administration. Three main results related to extent and duration of pain, quality of management of pain, and effect of pain on utilization of health services. Tonsillectomy caused considerable pain which lasted more than 7 days. Pain followed a trajectory of intense or moderately intense pain for the first 3 days followed by a gradual decline over the next 4 days. In general, post-tonsillectomy pain was poorly managed by health professionals and parents. An unexpected observation was that children who had a bupivacaine infiltration of the tonsil fossa during surgery had significantly more pain in the evening of surgery than children who did not have an infiltration. The increase in postoperative pain experienced by those who had the infiltration was attributed to quality of pain management. Children with persistent pain (those who did not follow the typical trajectory) were likely to be taken to a medical practitioner. One-third of the sample made unscheduled visits to practitioners with most occurring from Day 4 to Day 7 of the follow-up.

Insomnia is a significant problem for many people with chronic pain. In this study, we used a combination of daily sleep diaries and ambulatory activity monitoring (actigraphy) to: (i) examine the nature and severity of the sleep disturbance in this patient group; (ii) determine the concordance between sleep diary and actigraph measures of different sleep parameters; (iii) assess the reliability of sleep parameters across nights; and (iv) identify the clinical correlates of insomnia severity. Forty subjects with insomnia associated with chronic musculoskeletal pain completed questionnaires addressing clinical issues of pain severity, medication use, sleep quality, and affective distress. For 2 consecutive nights, each subject then completed a sleep diary and wore an actigraph unit on the non-dominant wrist. The results showed that the sleep diaries and the actigraphs provided similar estimates of total sleep time, time awake after sleep onset, and sleep efficiency, but differed in the measurement of sleep onset latency and nocturnal awakenings. Both methods of assessment exhibited low to moderate reliability across nights. Measures of the same sleep parameters across the two methods of assessment showed low concordance. Of the clinical variables, pain severity had the strongest association with disturbed sleep, but only using the diary method of assessment. Subjects who reported high pain severity also reported greater sleep impairment than subjects with low pain severity, but this was not confirmed by actigraphy. In general, both methods of assessment point to the significance of insomnia associated with chronic musculoskeletal pain as a distinct clinical problem, but the activity monitoring and self-report procedures provide different information. These findings suggest that multi-method assessment is an important consideration for studies of insomnia in patients with chronic pain.

The aim of this study was to: (i) test different instruments that focused on sleep, quality of life and personal adjustment in order to evaluate the usefulness of these instruments in a larger study; and (ii) to describe self perceptions of sleep and life situation by patients who had undergone coronary artery bypass grafting (CABG). A one-group pre-test repeated post-test design was used. Six men aged between 51 and 70 years were interviewed, and 24 h polysomnographic recordings were performed before and after the operation. The interviews indicated disturbed sleep and changes in behaviour and mental state immediately postoperatively. Postoperatively the polysomnographic recordings revealed a significant decrease in mean duration of sleep, mean percentage of stage 3-4 sleep and mean rapid eye movement (REM) sleep. One month after surgery the quality of life was improved, while moderate anxiety and sensation of incisional pain persisted. The measurements used in this pilot study provide valuable information into the understanding of altered sleep, quality of life and personal adjustment following CABG.
