Elaborating on the five-dimensional structure of illness representation, as described in the self-regulation model of Leventhal (1980), the present study is aimed at identifying the relevance of this generic structure for two chronic illnesses: chronic fatigue syndrome (CFS) and Addison's disease (AD). Factor analyses showed the importance of the five dimensions identity, time-line, control/cure, cause, and consequences to differ according to the type of disease. That is, the items representing the five dimensions merged together for CFS patients and AD patients in a different manner and thereby produced different factor solutions for the two patient groups. In CFS patients, a four-factor solution was identified with manageability, seriousness, personal responsibility, and external cause as the factors. In AD patients a four-factor solution was also identified but with seriousness, cause, chronicity, and controllability as the factors. The value of these findings for our understanding of the disease-specific nature of illness representation is discussed.

Two hundred and twenty-five subjects, including normal volunteers and patients with previously documented seasonal affective disorder (SAD), chronic fatigue syndrome (CFS), Cushing's syndrome, Addison's disease and obsessive-compulsive disorder (OCD), completed a self-rated inventory of reported sensitivity to various chemical exposures. Patients with CFS, Addison's disease and SAD self-reported more sensitivity to chemical exposures than normal controls. In addition, women reported more sensitivity than men. This report suggests that chemical sensitivity may be a relevant area to explore in certain medical and psychiatric populations. A possible relationship between reported chemical sensitivity and hypothalamic-pituitary-adrenal (HPA)-axis functioning is discussed.

Endocrinologists were not included in the multidisciplinary working groups that prepared two recent reports on chronic fatigue syndrome, despite its unequalled clinical overlap with Addison's disease, which is a classic endocrine disorder. The failure to include at least one endocrinologist in those panels may explain why in their extensive reports there is not a single word about the 42 clinical features that chronic fatigue syndrome shares with Addison's disease, including all the signs and symptoms listed in the case definition of this syndrome.

Although the clinical relevance of illness representations has been demonstrated in several studies, research on the structure and determinants of illness representations is rare. This article examines the illness representations of chronically ill patients, using a structured interview technique and taking chronic fatigue syndrome (CFS) and Addison's disease (AD) as examples. Considerable differences were found between the group of CFS patients (n = 98) and the group of AD patients (n = 63) with regard to their ideas about the identity, time line, control/cure , and consequences of their illness. Despite these differences, the pattern of correlations among these four dimensions of illness representation was found to be similar for the two groups. Moreover, the strength of the correlations points to the coherent nature of illness representations. The relations between the illness representations, personal variables, and disease- related variables were also explored. Regression analyses showed the dimensions of illness representation to be explained rather well by personal and disease-related variables. Disease-related variables were the most important predictors for the dimensions of identity and consequences; personal variables showed strong associations with time line and control/cure.

Adrenal histoplasmosis is an uncommon mycotic disease typically caused by Histoplasma capsulatum. The objective was to determine the clinicopathological findings in adrenal histoplasmosis. Pathological records were searched from the database at the Department of Pathology, Faculty of Medicine Ramathibodi Hospital, Mahidol University from 1993 to 2008 for cases of adrenal histoplasmosis. The keywords were "histoplasmosis" and "adrenal gland". Adrenal histoplasmosis was diagnosed by histopathology and Gomori-Grocott methenamine silver staining. Histoplasma capsulatum was confirmed by tissue culture and/or serology. The authors report seven cases of adrenal histoplasmosis in immunocompetent patients. The mean age at diagnosis was 67 years. All patients presented as chronic fatigue syndrome. The onset of symptoms ranged from one to three months. Addison's disease was found in adrenal histoplasmosis in one case (14.3%). The computed tomography revealed adrenal nodules measuring 1.2 to 7.8 cm in diameter. The histopathology showed granulomatous inflammation with caseous necrosis. Culture of adrenal tissue from two patients revealed Histoplasma capsulatum. Serum Histoplasma antibodies were positive in four cases. A cure was accomplished in 6 out of 7 cases (85.7%). The patients were followed up for 2.5 to 16.5 years.

Objective: To determine if patient self-administration of hydrocortisone will safely achieve superior symptom control for all hydrocortisone-responding disorders as it does for Addison's disease and rheumatoid arthritis. Methods: Two thousand four hundred and twenty-eight participants with hydrocortisone-responding disorders were brought to a minimum symptom state using daily administered hydrocortisone tablets in a 24-week, open study. Thereafter, participants used 5-day, low-dose hydrocortisone regimens to quench subsequent disorder exacerbations (flares) to maintain the minimum symptom state. Stressors such as emotional traumas, infections, allergies, and injuries were minimized to reduce disorder intensity, hydrocortisone consumption, and participant discomfort. Results: Two thousand fifteen participants, 601 with fibromyalgia, 579 with osteoarthritis, 246 with rheumatoid arthritis, 226 with undifferentiated arthritis, 75 with back pain, 51 with Parkinson's disease, 44 with polymyalgia rheumatica, 25 with neuropathy, 25 with chronic fatigue syndrome, 25 with dementia, 21 with migraine headache, 19 with multiple sclerosis, and 78 with other disorders completed the 24-week study to achieve a composite average symptom improvement of 76% with equal response rates. The participants averaged ingesting 12 mg of hydrocortisone per day. No significant adverse reactions were observed. Conclusions: Patient self-administration of hydrocortisone safely achieves superior symptom control for 38 hydrocortisone-responding disorders at equal rates and symptom improvements to confirm and amplify an earlier double-blind study finding on rheumatoid arthritis. These results are consistent with the body having an inflammation control system and chronic inflammation being a disorder unto itself with differing symptoms sets dependent on its location. Clinical Trials Government Identifier: NCT03558971.
