Chronic fatigue and indicators of long-term employment disability in psychosomatic inpatients

The major goal of this study was to determine indictors of long-term disability for psychosomatic inpatients with chronic fatigue syndrome. To this end, a cross-sectional study was performed with a random sample of patients (n=1000, response rate: 83.9%) at a psychosomatic inpatient clinic. 51.1% of the patients (n=429) reported intensely persistent exhaustion that had no logical relation to actual exertion. 159 (37.1%) patients in this group were disabled from working and these comprised the main target group of this study. Significantly more patients in the target group worked part time, were disabled for a disproportionately long period of time (50.9% of all were disabled for more than 6 months in the previous year), and felt stressed because of conflicts with their superiors and/or colleagues (in each case, P<0.01). While more frequent psychological comorbidity was not found, they reported physical complaints more often. It was not the patients fit for work who felt more burdened with chronic fatigue, but rather the employment-disabled, who were actually exposed to fewer demands. These patients had, in comparison with those fit to work, a stronger fixation on somatic complaints, inadequate perception of physical and psychic sensations, difficulties getting along with other people and in coping with a regular job (in each case, P<0.01). Prospective examination of these indicators could help detect predictor variables for long-term disability in chronic fatigue. Such predictors could contribute to timely social-medical assessment and treatment.     

Lower Placebo Responses After Long-Term Exposure to Fibromyalgia Pain

Knowledge about placebo mechanisms in patients with chronic pain is scarce. Fibromyalgia syndrome (FM) is associated with dysfunctions of central pain inhibition, and because placebo analgesia entails activation of endogenous pain inhibition, we hypothesized that long-term exposure to FM pain would negatively affect placebo responses. In our study we examined the placebo group (n = 37, mean age 45 years) from a 12-week, randomized, double-blind, placebo-controlled trial investigating the effects of milnacipran or placebo. Twenty-two patients were classified as placebo nonresponders and 15 as responders, according to the Patient Global Impression of Change scale. Primary outcome was the change in pressure pain sensitivity from baseline to post-treatment. Secondary outcomes included ratings of clinical pain (visual analog scale), FM effect (Fibromyalgia Impact Questionnaire), and pain drawing. Among placebo responders, longer FM duration was associated with smaller reductions in pressure pain sensitivity (r = .689, P = .004), but not among nonresponders (r = ?.348, P = .112). In our study we showed that FM duration influences endogenous pain regulation, because pain levels and placebo-induced analgesia were negatively affected. Our results point to the importance of early FM interventions, because endogenous pain regulation may still be harnessed at that early time. Also, placebo-controlled trials should take FM duration into consideration when interpreting results.

Pathologic breast conditions in childhood and adolescence: evaluation by sonographic diagnosis.

OBJECTIVE: The growing awareness of female breast cancer has led to increased sensitivity toward pathologic breast conditions in children and adolescents. Thus, approximately 15% of patients in child and adolescent gynecology are referred for the first time because of conspicuous features of the breast such as pain, palpable masses, and other findings on visual inspection. The aim of this study was to analyze the underlying diagnoses and diseases and determine the status of breast sonography in the diagnostic process. METHODS: The study population consisted of 62 female patients between 8 weeks and 20 years of age (1997-2002) who were examined clinically, followed by standardized sonography (7.5-13 MHz, conventional B-mode panoramic sonography). Presumed diagnoses were confirmed by biopsy in some patients (n = 16) and by follow-up with clinical examination and sonography in most cases (n = 46). RESULTS: The clinical and sonographic evaluation confirmed 4 main groups of diagnoses: benign tumors (15), developmental disturbances (14), cystic changes (11), and inherent defects (7). In the remaining cases, the findings were no abnormality (9), nipple discharge without evidence of pathologic or morphologic correlates (3), abscesses (2), and epidermoid cyst (1). CONCLUSIONS: Knowledge of regular breast development and its variants is essential for the physician. Given knowledge of the sonographic appearance of physiologic breast development and specific lesions, breast sonography is most helpful in identifying and characterizing abnormalities and guiding further investigation.     

Sarcoidosis

Sarcoidosis is a systemic granulomatous disease of unknown cause affecting young and middle-aged adults. Patients commonly present with bilateral hilar lymphadenopathy, pulmonary infiltrates, and ocular and skin lesions. The heart, liver,spleen, salivary glands, muscles,bones, kidneys, and central nervous system also may be involved. Diagnosis is based on clinicoradiologic findings plus histologic evidence of noncaseating epithelioid granulomas, and exclusion of other granulomatous diseases. Prognosis correlates with mode of onset, host characteristics, initial clinical course, and extent of disease. The optimal management of sarcoidosis has not been well defined. Although corticosteroids remain the mainstay of treatment, there is little evidence for the optimal initiation, dosage, or duration of therapy. Topical steroids maybe considered for treatment of anterior uveitis and skin lesions. Systemic steroids are indicated for treatment of cardiac, nervous system, severe ocular, and symptomatic or progressive pulmonary involvement. There is little evidence for the efficacy of inhaled steroids. Cytotoxic agents and immunomodulators usually are reserved for treatment of complex or refractory disease. Of these agents, methotrexate is used more frequently because of its safety profile and possible steroid-sparing effects. Antimalarial agents are used frequently for skin lesions, and they have limited success in the treatment of pulmonary disease. Lung and cardiac transplantation is reserved for end-stage disease. Monitoring for symptoms of drug toxicity is essential, and prevention of osteoporosis must be addressed in patients taking long-term oral corticosteroids. It is not known if current therapy alters disease progression.     

Impact of Early Salvage Radiation Therapy in Patients with Persistently Elevated or Rising Prostate-specific Antigen After Radical Prostatectomy

Background

Salvage radiation therapy (SRT) is a recommended treatment option for biochemical recurrence after radical prostatectomy (RP). However, its effectiveness may be limited to specific categories of patients.

Possible links between behavioral and physiological indices of tiredness, fatigue, and exhaustion in advanced cancer

Goals In this theoretical paper, we present the Edmonton Fatigue Framework (EFF), a new framework for the study of tiredness, fatigue, and exhaustion in advanced cancer. Materials and methods The Fatigue Adaptation Model (FAM), the starting point for the EFF, was drawn from a literature review pertaining to fatigue in depression, chronic fatigue syndrome, cancer, shift workers, and athletes published in the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, PsychINFO, SPORTdiscus, and CancerLit between 1995 and 2004, and from seven qualitative studies conducted by our group. The EFF, an elaboration of the FAM, was constructed after an expansion of our literature review to 2006 and team discussion. The EFF provides new insights into possible links between behavioral and physiological indices of tiredness, fatigue, and exhaustion as they occur in both ill and non-ill states. In this paper, however, we consider only possible links in advanced cancer. Conclusions We propose that stressors associated with advanced cancer and its supportive treatment trigger declines in four systems—cognitive function, sleep quality, nutrition, and muscle endurance—and that these declines reduce one’s ability to adapt. While these systems each likely has its own effect on adaptation, we propose that the most important and serious effects arise from interactions among declines in cognitive function, sleep quality, nutrition, and muscle endurance. Conclusions Interventions for fatigue have been limited by a lack of understanding about its etiology. Hypotheses arising from the EFF` suggest a new direction for further study that focuses on interactions among cognitive function, sleep quality, nutrition, and muscle endurance.     

Using the new OASIS-based reports in OBQI

OASIS-derived outcome reports first became available to home care agencies in February 2002 and depicted the agency's current (observed) outcome achievement rate as compared to a reference (predicted) rate on 41 separate outcomes. New three-bar reports are now available that allow agencies to evaluate their current outcome rates against their previous year's rates and a reference rate. This article compares the newly-available three-bar reports with the prior two-bar reports, including information provided in those reports in the OBQI process.     

Physician discussions with terminally ill patients: a cross-national comparison

A major issue in the care of terminally ill patients is communication and information provision. This paper reports the extent to which physicians in Australia, Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland discuss topics relevant to end of life care with terminally ill patients and their relatives (without first informing the patient), and possible associations between physician-specific characteristics and such discussions. Response rates to the postal survey ranged from 39% to 68% (n =10139). Physicians in most of the countries except Italy ;in principle, always' discuss issues related to terminal illness with their patients but not with patients' relatives without first informing the patient, unless the relatives ask. Cross-national differences remained strong after controlling for physician characteristics. The majority of physicians appeared to support the principle of patient-centred care to terminally ill patients, consistent with palliative care philosophy and with the law and/or professional guidelines in most of the countries studied.
