Pain is a perceived threat or damage to one's biological integrity. Suffering is the perception of serious threat or damage to the self, and it emerges when a discrepancy develops between what one expected of one's self and what one does or is. Some patients who experience sustained unrelieved pain suffer because pain changes who they are. At a physiological level, chronic pain promotes an extended and destructive stress response characterised by neuroendocrine dysregulation, fatigue, dysphoria, myalgia, and impaired mental and physical performance. This constellation of discomforts and functional limitations can foster negative thinking and create a vicious cycle of stress and disability. The idea that one's pain is uncontrollable in itself leads to stress. Patients suffer when this cycle renders them incapable of sustaining productive work, a normal family life, and supportive social interactions. Although patients suffer for many reasons, the physician can contribute substantially to the prevention or relief of suffering by controlling pain. Suffering is a nebulous concept for most physicians, and its relation to pain is unclear. This review offers a medically useful concept of suffering that distinguishes it from pain, accounts for the contributory relation of pain to suffering by describing pain as a stressor, and explores the implications of these ideas for the care of patients.

The aim of this study was to examine the prevalence of depression and anxiety following coronary artery bypass surgery (CABG) and to see how those patients with depression and anxiety differ in sleeping pattern. The individual reaction to sleep loss was tested as a predictor of certain emotional symptoms in the follow-up period. Thirty-eight males, between 45 and 68 years, were interviewed prior to, and 1 month after, surgery, and received a questionnaire at the 6-month follow-up. Eighty per cent scored moderate anxiety prior to surgery and six patients were depressed. An anxiety-prone individual reactivity persisted in the same patients in 38.9% (n = 14) following CABG, with significantly more sleep disturbances, firedness, energy deficits, immobility, and lower degree of quality of life (QoL). Sad/depressed mood or cognitive/behavioural fatigue symptoms as reactions to sleep loss were predictors of sleep problems and daytime sequelae, whereas a higher postoperative NYHA class was predicted by cognitive/behavioural fatigue and dysphoria reactions. Being less refreshed by sleep on final awakening prior to surgery related to 44.5% of the variance in QoL outcome 6 months following surgery. In conclusion, an anxiety-prone individual reactivity is significantly associated with sleep disturbances. Reactions to sleep loss prior to surgery are associated with emotional distress after surgery.

The aim of this study was to compare the effect of treatment with lamotrigine (LTG) or carbamazepine (CBZ) on health-related quality of life (HRQOL) and to demonstrate the use of the SEALS Inventory as a comparative tool in clinical trials. Two hundred and sixty patients with newly diagnosed epilepsy were randomized to 48 weeks of treatment with LTG (n = 131) or CBZ (n = 129). HRQOL was measured at baseline and weeks 4, 12, 24, and 48 using the modified Side Effect and Life Satisfaction (SEALS) Inventory-a 38-item questionnaire divided into five subscales: Worry, Temper, Cognition, Dysphoria, and Tiredness. Overall, SEALS scores in the LTG group decreased (improved) significantly from baseline (P = 0.001). The LTG group had improvement in all five subscales over the 48 weeks of the study. CBZ patients had significantly worse SEALS scores than LTG patients at week 4 (P < 0.038). There was no significant change (positive or negative) in subsequent SEALS assessments. Analysis of SEALS data by subscale showed that the the CBZ group experienced more cognitive side-effects in general and more general changes in energy levels and affect during the first 4 weeks of treatment. These changes may help explain the difference in study completion rate: LTG 65%, CBZ 51% (P = 0.018). LTG offers the patient with newly diagnosed epilepsy significant benefits of greater tolerability and better health-related quality of life compared with CBZ. The SEALS Inventory is an effective tool for use in clinical trials of AEDs; it was a better predictor of trial completion than seizure counts, and used as a covariate enabled better detection of treatment effects. In general practice, the use of the SEALS Inventory to assess HRQOL has the potential to improve quality of care for people with epilepsy.

1. The aim of this study was to examine degrees of cognitive behavioural effects of fatigue, mood changes and somatic responses to sleep loss in women with and without sufficient sleep, and to explore possible links between effects of sleep loss and specific sleep disturbances in selected groups. 2. A total 156 women working in a casualty department on different work shifts responded to a questionnaire which measured sleep quality, strain and symptoms related to working conditions, as well as effects of sleep loss. 3. About 40% of the women had perceived insufficient sleep during the last 6 months. They perceived significantly worse sleep quality and a higher degree of strain according to working conditions than the others. Palpitation and dysphoria as effects of sleep loss were independently predicted by sleep quality. Dysphoria was also predicted by difficulty in falling asleep. Cognitive behavioural effects of fatigue was predicted by disturbed sleep. Palpitation effects led to a 10-fold increase in the probability of cognitive behavioural effects of fatigue. The effects were most prominent among women suffering from gastrointestinal problems of long duration and chronic pain. 4. Responses to reduced sleep quality in women constitute a form of stress, with sympathetic activation, increased susceptibility to infection, moderate cognitive impairment, mood changes and somatic distress.

Although the construct of "a symptom-free day" has been widely applied in asthma and gastric reflux disease, there is no analogous concept in the field of pain management. This study represents the initial development of a "day of acceptable or manageable pain control," a construct which reflects patients' daily strategic use of pain medication in order to allow the accomplishment of desired activities while minimizing side effects. Focus group methodology was used to extract patient-generated themes of "an acceptable day of pain control." Fifty-three outpatients with persistent moderate to severe average pain intensity due to osteoarthritis (n=18), metastatic cancer (n=15), and low back pain (n=20) participated. Participants preferred the term "manageable" or "tolerable" to "acceptable." Thematic analysis revealed components of a manageable/tolerable day of pain control as including: 1) taking the edge off the pain, 2) performing valued activities; 3) relief from dysphoria and irritability; 4) reduced medication side effects; 5) feeling well enough to socialize. Additional cancer-specific themes included relief from fatigue and ability to have a positive day when one's future days were perceived as being limited. The set of themes is presented and their relevance for developing a measure of "a manageable day of pain control" discussed. Study findings identify a novel construct that can inform development of an outcome for evaluating the effectiveness of different pharmacotherapies for pain management.

Naltrexone treatment has demonstrated some advantages for special populations of heroin addicted individuals, but patients' compliance seems to be very poor, with a low adherence and low retention rate. Kappa-opioid system overdrive seems to contribute to opioid protracted abstinence syndrome, with dysphoria and psychosomatic symptoms during naltrexone treatment. The objective of this observational study was to determine the effectiveness of a functional k antagonist in improving naltrexone treatment outcome. A partial mu agonist/kappa antagonist (buprenorphine) and a mu antagonist (naltrexone) were combined during a 12 weeks protocol, theoretically leaving k antagonism as the major medication effect. Sixty patients were submitted to outpatient rapid detoxification utilizing buprenorphine and opioid antagonists. Starting on the fifth day, 30 patients (group A) received naltrexone alone. Alternatively, 30 patients (group B) received naltrexone (50mg oral dose) plus buprenorphine (4 mg sublingual) for the 12 weeks of the observational study. The endpoints of the study were: retention in treatment, negative urinalyses, changes in psychological symptoms (Symptom Checklist-90 Revised: SCL-90) and craving scores (visual analysis scale (VAS)). Thirty-four subjects (56.67%) completed the 12 weeks study. Twenty-one patients (35.0%) had all urine samples negative for opiates and cocaine. nine subjects (15.0%) had urine samples negative for cocaine and opiates for the last 4 weeks of the study. five subjects (8.3%) continued to use cocaine during the 12 weeks of the study. No significant change in pupillary diameter after buprenorphine administration was evidenced during clinical observations from baseline across the weekly measurements. Retention rates in group A (naltrexone) and group B (naltrexone + buprenorphine) at week 12 were respectively 40% (12 patients) and 73.33% (22 patients), with a significant difference in favour of group B (p= 0.018). Patients treated with naltrexone in combination with buprenorphine (B patients) showed a significantly lower rate of positive urines for morphine (4.45%) and cocaine metabolites (9.09%) than those treated with naltrexone alone (A) (25%, morphine; 33.33% cocaine) (p< 0.05; p< 0.05). Irritability, depression, tiredness, psychosomatic symptoms and craving scores decreased significantly less in Group A patients than in group B patients. The dysfunction of opioid system with kappa receptors hyper-activation provoked by heroin exposure, probably underlying dysphoric and psychosomatic symptoms during naltrexone treatment, seems to be counteracted, at least in part, by buprenorphine. The combination of buprenorphine and naltrexone may significantly improve the outcome of opioid antagonists treatment in terms of retention, negative urinalyses, and reduced dysphoria, mood symptoms and craving.

Rumination can prolong negative mood, disrupt sleep, and increase depression risk. Although there is evidence that poor sleepers ruminate, no studies have identified the ruminative content relevant for sleep disturbance. This study investigated (a) the association between rumination and sleep and (b) the ruminative content of poor sleepers. Results revealed that self-defined poor sleepers (n = 104) were more prone than self-defined good sleepers (n = 139) to ruminate and that the ruminative content was symptom focused (e.g., poor sleepers ruminated on causes of dysphoria, concentration, and fatigue symptoms). As dysphoria, reduced concentration, and fatigue are all commonly experienced daytime symptoms of insomnia, this preliminary finding of symptom-focused rumination should be further evaluated as a risk factor for further sleep disturbance in clinical samples as well as a possible link between insomnia and depression.

Recently in Japan dioxin problem of municipal solid waste incinerator (MSWI) became social issue. The news spread all around Japan and induced fear that workers at incinerators would suffer from cancer or other serious illness induced by the exposure to dioxins. Authors were interested in the effect of this stressful event occurred to the workers and intended to evaluate mental health status of MSWI workers compared with office workers. Subjects were male workers from two MSWI plants and a local government office; 20 government office workers who were engaging in health administration and 55 MSWI workers. Subjects were interviewed about their age, educational carrier, and working schedule. POMS and GHQ30 were used to evaluate mood status of subjects. There were differences in mood state between the two occupational groups. POMS showed that Tension-Anxiety, Depression-Dejection, and Fatigue levels were high in the health administration worker group. GHQ30 showed that General Illness, Social Dysfunction, and Anxiety and Dysphoria state were deviated to abnormal in the health administration worker group. General mental health status evaluated by GHQ30 score was also deviated to abnormal in the office worker group. Our results showed that mental health status of health administration workers was less healthy compared with MSWI workers. This meant that the stress of MSWI workers enhanced by the fear that they might have been exposed to dioxin did not exceed the stress the health administration workers usually had suffered from.

Progesterone is a steroid hormone that is important for reproductive function. Progesterone is used in a number of clinical applications and has been investigated as a possible novel approach for treatment of stimulant drug abuse. Extensive clinical studies have been conducted to examine the subjective and physiological effects of exogenous progesterone administration and to evaluate its side effects. This review summarizes the safety and side effects of acute and chronic administration of 3 progesterone formulations (synthetic, natural, and micronized natural), several routes of administration (oral, intramuscular, intravenous, intravaginal, intranasal, transdermal, and rectal), and dosing regimens. Synthetic progestins marketed as Provera, PremPro, and Cycrin are widely used but may produce a number of significant side effects, such as fatigue, fluid retention, lipid level alterations, dysphoria, hypercoagulant states, and increased androgenicity. Natural progesterones are reported to have milder adverse effects, depending on the route of administration. Micronized natural progesterone is available for oral administration, has better bioavailability and fewer side effects than natural progesterone, and is convenient to administer. Therefore, micronized natural progesterone appears to be a safe and effective alternative to synthetic and natural progesterone formulations for variety of clinical and research applications.

Residents on call experience decreased total sleep time (TST) and increased dysphoria. This study monitored changes in mood and sleepiness for 3 post-call days. Fifty-two internal medicine residents participated in the study. The residents wore actigraphs for the 4 to 9 days of the study. Each morning resident completed mood scales, a sleepiness scale, and estimated their prior night TST. The residents were on a 1-in-4 schedule. Call decreased subjective- and actigraphy-derived TST to less than 4 hr. During the 3 days post call, mood measures improved. Tension, depression, and anxiety stabilized on the first post-call day following the first night of off-call sleep during which the residents obtained about 7 hr of sleep. Vigor, fatigue, and confusion stabilized on the second post-call day. The Epworth Sleepiness Scale dropped to less than 11 after 1 post-call night and continued to decrease up to 3 post-call days. The effects of call linger past the first recovery night. For these residents, recovery sleep appeared inadequate, and the negative effects of call persisted across succeeding off-call days. Thus, for these residents on a 1-in-4 schedule, call affects their mood for much of the time when off call and potentially their personal and professional interactions during this period as well.
