This study measured work limitations and work adjustments among chronically ill employees with regard to three distinct job characteristics: physical work demands, cognitive work demands and social work demands. The study presents findings from an organizational-based survey, from which 610 respondents reported managing employees with a chronic illness. These included arthritis, musculoskeletal pain, diabetes, asthma, migraine, heart disease, irritable bowel syndrome and depression. The results indicate that depression had the largest impact in all three work demand categories, while musculoskeletal pain principally affected physical work demands and migraine and diabetes largely affected cognitive work demands. For other chronic illnesses, it was the generic symptoms of the illness (for example, fatigue) that resulted in a work limitation, rather than the specific nature of the illness itself. Employer work adjustments were available to those people with illnesses that required a physical work adjustment (for example, musculoskeletal pain). For other chronic illnesses, with the exception of depression, disclosing an illness was the strongest predictor for work adjustments in cognitive tasks and the provision of social support. Those with depression were least likely to receive a cognitive work adjustment, indicating either a low disclosure rate in this group or that employers' perceptions of depression may be a barrier to providing suitable work adjustments.

Irritable bowel syndrome (IBS) is a common gastrointestinal motility disorder that typically affects persons of working age and is costly to employers. The financial burden attributable to the direct (use of healthcare resources) and indirect (missed days from work [absenteeism] and loss of productivity while at work [presenteeism]) costs of IBS is similar to that of other common long-term medical disorders, such as asthma, migraine, hypertension, and congestive heart failure. The symptoms of IBS are significantly bothersome and place a substantial burden on the personal and working lives of patients. As with other long-term medical conditions that have a significant impact on productivity, directed efforts by employers can address IBS in the workplace and thereby potentially decrease its impact. In this article, the symptoms of IBS and its impact on patients and on society as a whole are discussed; options are outlined by which employers can help reduce the total costs of IBS, including lost productivity (both absenteeism and presenteeism), in the workplace.

There is convincing evidence that acupuncture (AP) is effective for the treatment of postoperative and chemotherapy-induced nausea/vomiting, as well as postoperative dental pain. Less convincing data support AP's efficacy for chronic pain conditions, including headache, fibromyalgia and low back pain. There is no evidence that AP is effective in treating addiction, insomnia, obesity, asthma or stroke deficits. AP seems to be efficacious for alleviating experimental pain by increasing pain thresholds in human subjects and it appears to activate analgesic brain mechanisms through the release of neurohumoral factors, some of which can be inhibited by the opioid antagonist naloxone. In contrast to placebo analgesia, AP-related pain relief takes some time to develop and to resolve. Furthermore, repetitive use of AP analgesia can result in tolerance that demonstrates cross-tolerance with morphine. However, it appears that not all forms of AP are equally effective for providing analgesia. In particular, electro-AP seems to best deliver stimuli that activate powerful opioid and nonopioid analgesic mechanisms. Thus, future carefully controlled clinical trials using adequate electro-AP may be able to provide the necessary evidence for relevant analgesia in chronic pain conditions, such as headache, fibromyalgia, irritable bowel syndrome and low back pain.

Chronic pelvic pain (CPP) is a common condition in women and rates of consultation for CPP in general practice are similar to those for asthma and migraine. US and UK population-based studies, together with data from UK hospital settings demonstrate a substantial impact of CPP on health-related quality of life. In this review, we will examine the current evidence on the aetiology and management of CPP, focussing on the randomised controlled trials (RCTs) that are available to date. CPP is a heterogeneous condition and causation is often unclear. There are associations with specific pathological processes but a barrier to understanding is that many studies have data that are not comparable. In the community setting, as many as 60% of women with CPP have not received a specific diagnosis and up to 20% have not undergone any investigation. The factor most commonly associated with CPP in the community is irritable bowel syndrome, although in a tertiary setting with laparoscopy, pathology associated with CPP in ascending order of frequency is endometriosis (33%), adhesions (24%) and 'no pathology' (35%). Current RCT evidence provides some support for the use of ultrasound scanning as an aid to counselling and reassurance, progestogen (medroxyprogesterone acetate) or goserelin for pelvic congestion and a multidisciplinary approach to assessment and treatment. Adhesiolysis is not shown to be of benefit other than in women with extensive adhesions. While studied in relation to dysmenorrhoea rather than CPP, the short term results for presacral neurectomy (PSN) and laparoscopic utero-sacral nerve ablation (LUNA) seem to be similar, although PSN has better results in the long term. Selective serotonin reuptake inhibitor (SSRI) antidepressants have not been shown to be of benefit in CPP. Most of these conclusions are based on the outcome of single randomised trials and therefore need replication.

Gastroesophageal reflux disease (GERD), functional dyspepsia and irritable bowel syndrome (IBS) often coexist and may share a common pathophysiological mechanism. An association between GERD and asthma has been reported, and IBS patients have been shown to have an excess prevalence of bronchial hyperresponsiveness. Patients with overlapping IBS and dyspepsia have delayed gastric emptying rates as well as increased visceral hypersensitivity in both the colon and the stomach. Postinfectious occurrence of concomitant dyspepsia and IBS has also been reported, as has a familial association in functional gastrointestinal disorders. Although GERD, dyspepsia and IBS are highly prevalent conditions, overlapping symptoms should be not be attributed to their high prevalence but to a possible common disease process in a subset of patients.

Urocortins, three paralogs of the stress-related peptide corticotropin-releasing factor (CRF) found in bony fish, amphibians, birds, and mammals, have unique phylogenies, pharmacologies, and tissue distributions. As a result and despite a structural family resemblance, the natural functions of urocortins and CRF in mammalian homeostatic responses differ substantially. Endogenous urocortins are neither simply counterpoints nor mimics of endogenous CRF action. In their own right, urocortins may be clinically relevant molecules in the pathogenesis or management of many conditions, including congestive heart failure, hypertension, gastrointestinal and inflammatory disorders (irritable bowel syndrome, active gastritis, gastroparesis, and rheumatoid arthritis), atopic/allergic disorders (dermatitis, urticaria, and asthma), pregnancy and parturition (preeclampsia, spontaneous abortion, onset, and maintenance of effective labor), major depression and obesity. Safety trials for intravenous urocortin treatment have already begun for the treatment of congestive heart failure. Further understanding the unique functions of urocortin 1, urocortin 2, and urocortin 3 action may uncover other therapeutic opportunities.

The increasing prevalence of both asthma and irritable bowel syndrome (IBS) are major health problems. One hundred twenty-five patients with asthma and 95 healthy subjects were included in this study. The rate of IBS was 29.6% and 12.7% (p < 0.005), and the incidence of food allergy was 7.2% and 2.1% (p > 0.05) respectively for asthma and control group. There was no significant association between asthma related parameters, IBS, and food allergy. There is not a single clear reason as to what causes IBS, so further studies are needed to clarify the potential pathogenic mechanisms underlying the association between IBS and asthma.

We conducted a study to examine the relation of asthma and its treatment to irritable bowel syndrome (IBS). We identified cohorts of members with and without asthma from January 1996 though June 2002 and calculated rates of IBS in both cohorts. In a nested case-control study, we calculated odds ratios for oral steroid dispensing before IBS onset. To address differential IBS detection, we conducted a quantitative sensitivity analysis. We identified 91,237 people with asthma and sample of 24,518 people without asthma. There was a 20% increase in the incidence of IBS among people with asthma (standardized morbidity ratio = 1.2; 95% CI, 1.0-1.5), and no association between oral steroids and IBS among people with asthma (OR = 1.0; 95% CI, 0.9-1.1.) Misclassification of IBS would have biased the rate ratio toward the null. We observed a small increase in IBS among people with asthma, and no association between oral steroids and IBS onset among asthma patients.

Sleep is vital to health and quality of life while sleep abnormalities are associated with adverse health consequences. Nevertheless, sleep problems are not generally considered by clinicians in the management of chronic inflammatory conditions (CIC) such as asthma, RA, SLE and IBD. To determine whether this practice is justified, we reviewed the literature on sleep and chronic inflammatory diseases, including effects of sleep on immune system and inflammation. We found that a change in the sleep-wake cycle is often one of the first responses to acute inflammation and infection and that the reciprocal effect of sleep on the immune system in acute states is often protective and restorative. For example, slow wave sleep can attenuate proinflammatory immune responses while sleep deprivation can aggravate those responses. The role of sleep in CIC is not well explored. We found a substantial body of published evidence that sleep disturbances can worsen the course of CIC, aggravate disease symptoms such as pain and fatigue, and increase disease activity and lower quality of life. The mechanism underlying these effects probably involves dysregulation of the immune system. All this suggests that managing sleep disturbances should be considered as an important factor in the overall management of CIC.

The NK(2) receptor belongs to the family of tachykinin neurotransmitters. It has been reported to be involved in several pathological conditions, and selective antagonists are potentially useful drugs for the treatment of asthma, irritable bowel syndrome, cystitis, and depression. Starting from in-house capped dipeptide libraries, we were able to identify a number of molecules with sub-nanomolar binding affinity for the hNK(2) receptor. All were characterized by a rigid core structure with a strong constraint induced by an alpha,alpha-cyclopentaneglycine fragment. Herein we report the further elaboration of three initial basic structures. The planar benzothiophene group was substituted with a series of biphenyl and heterobiphenyl moieties that are well tolerated in terms of receptor affinity. The new compounds also maintained good antagonist potency in an in vitro functional assay, and a number of them showed significant in vivo activity after intravenous administration in our guinea pig model.
