Acute and chronic radiotherapy-related fatigue occurs in up to 80% and 30%, respectively, of patients undergoing irradiation for cancer. Frequently, the symptom is not expected by the patients and is underestimated by medical and nursing staff. Fatigue can affect global quality of life more than pain, sexual dysfunction and other cancer- or treatment-related symptoms. Its etiology and correlates are not clear. Published reports are mainly descriptive, and in many of them numerous methodological biases are present. One of the limitations is lack of a standard method of assessment that could simplify the comparison between different series. In the last decade, modern instruments have been designed to measure fatigue. They include uni- and multidimensional tools. Use of these specific instruments is highly recommended for research on radiation-related fatigue. In daily practice when time is limited, simple assessment is necessary. For example, systemic use of plain and easily understandable questions about fatigue, its level and impact on daily life could be sufficient and reliable. Therapeutic strategies for radiotherapy-induced fatigue have not yet been clearly defined, but a few randomized studies have been recently published. Physical exercise, group psychotherapy and relaxation therapy have been demonstrated to be effective. Moreover, pharmacological treatment of concomitant disturbances (anemia, pain, insomnia, depression, dehydration, infection, malnutrition) and other radiotherapy side effects (diarrhea, hormonal insufficiency etc.) should be considered. Further methodologically correct studies are warranted to better define the causes, optimal prevention, assessment and management of this symptom.

Chronic fatigue (CF) is one of the most common conditions reported by Gulf War veterans. This study evaluated female sexual dysfunction (FSD) in veterans with or without complaints of CF. Subjects were screened for medical and psychiatric causes of CF. They included 22 healthy subjects and 26 with fatiguing symptoms. FSD was reported by 10% of controls and by 60% of the fatigued (p < .002) while 19% versus 81% (p < .001) noted decreased libido. FSD was more prevalent in fatigued veterans than in the controls. This relationship was not mediated by an Axis I diagnosis. This appears to be the first report of sexual dysfunction in CF.

Radiotherapy-induced fatigue is a common early and chronic side-effect of irradiation, reported in up to 80 and 30% of patients during radiation therapy and at follow-up visits, respectively. It is frequently underestimated by medical and nursing staff, only about 50% of patients discuss it with a physician and in one fourth of cases any intervention is proposed to the patient. The patients rarely expect fatigue to be a side-effect of treatment. The etiology of this common symptom, its correlates and prevalence are poorly understood. In numerous studies the level and time course of fatigue was demonstrated to depend on the site of tumor and treatment modalities. For example, psychological mechanisms have been proposed to explain fatigue in women receiving irradiation for early breast cancer, whereas decline in neuromuscular efficiency rather than psychological reasons can lead to the fatigue observed in patients undergoing radiotherapy for prostate cancer. Fatigue can affect global quality of life more than pain, sexual dysfunction and other cancer- or treatment-related symptoms. Several interventions have been tested in the management of radiotherapy-related fatigue and some randomized studies have been recently published. Although an optimal method has not yet been established, some promising results have been reported with relaxation therapy, group psychotherapy, physical exercise and sleep. Further methodologically correct studies are warranted to define better the causes, optimal prevention and management of this symptom.

Quality of Life (QOL) is impaired in multiple sclerosis (MS) in part due to physical disability. MS-associated fatigue (MSF) and depression (MSD) are common and treatable features of MS, which could also impact on QOL, independent of physical disability. We prospectively studied 60 consecutive patients with MS. QOL was assessed using Multiple Sclerosis Quality of Life (MSQOL)-54. Group differences in QOL scores were assessed after adjusting for Expanded Disability Status Scale (EDSS), Fatigue Severity Scale (FSS) and Hamilton Depression Inventory scores. MS patients were grouped into relapsing-remitting (RR) or secondary-progressive (SP), MSF (FSS> or =5) or MS-nonfatigue (MSNF) (FSS< or =4), and MSD or MS-nondepression (MSND). After accounting for disability and depression, fatigue was associated with impaired QOL with respect to health perception (p=0.03) and limitations due to physical dysfunction (p=0.008). After accounting for disability and fatigue, depression was associated with lower QOL with respect to health perception (p=0.02), sexual dysfunction (p=0.03), health distress (p=0.03), mental health (p=0.006), overall QOL (p=0.006), emotional dysfunction (p=0.04), and limitations due to emotional dysfunction (p=0.03). This study demonstrates that fatigue and depression are independently associated with impaired QOL in MS, after accounting for physical disability, suggesting that their recognition and treatment can potentially improve QOL.

We report the case of a 53 year old patient who was admitted with polyuria, polydipsia associated with fatigue, depression and sexual dysfunction. Central diabetes insipidus with hypogonadotrophic hypogonadism was diagnosed by a water restriction test and different static and dynamic hormonal dosages. Nodular thickening of the pituitary stalk was noted on the MRI and the biopsy permitted a histological diagnosis of infundibulitis.

In contrast to women, men do not experience a sudden cessation of gonadal function comparable to menopause. However, there is a progressive reduction in hypothalamic-pituitary-gonadal (HPG) function in aging men: testosterone (T) levels decline through both central (pituitary) and peripheral (testicular) mechanisms and there is a loss of the circadian rhythm of T secretion. In cohorts of men 75 years of age, mean plasma T levels are 35% lower than comparable young men, and more than 25% of men over 75 appear to be T-deficient. Such age-associated T deficiency, which has been termed 'andropause', is thought to be responsible for a variety of symptoms experienced by elderly men, such as weakness, fatigue, reduced muscle and bone mass, impaired haematopoiesis, oligospermia, sexual dysfunction, depression, anxiety, irritability, insomnia and memory impairment. However, it has been difficult to establish correlations between these symptoms and plasma T levels. Nevertheless, there is some evidence that T replacement leads to symptom relief, particularly with respect to muscle strength, bone mineral density, and haematopoiesis. Studies to date on the specific association between psychiatric symptoms, such as depressed mood, and T levels have been methodologically flawed. Overall, data suggest that although hypogonadism is not central to major depressive disorder (MDD), HPG hypofunction may have aetiological importance in mild depressive conditions, such as dysthymia.

Multiple sclerosis (MS) is the most common disease of the central nervous system affecting people between the ages of 20 and 40 years in the UK, Northern Europe and the USA. No definitive treatment yet exists to halt the almost inevitable decline in function and accumulation of disability over the years in sufferers. Management is largely directly of symptoms which arise variably in the course of the condition. Such problems as urinary incontinence, sexual dysfunction, cramps and spasms, tremor and trigeminal neuralgia can often be helped to some extent using conventional therapies. These treatments though are not effective in everyone, or cause unacceptable side-effects and there are some commonly reported symptoms, such as fatigue or emotional lability for which there are no generally accepted treatments. Here, a knowledge of complementary and alternative medicine (CAM) can bring benefits to the person with MS. CAM is widely used by people with MS and some studies in this area are briefly summarised. It is interesting to reflect what lies behind all this CAM use and what that might tell conventional medicine about just what it is the MS sufferer really wants from their carers. Homeopathy is a form of CAM unique in the UK in having been available in the NHS since the foundation in 1948. Medical homeopaths in the UK have always been concerned with the integration of the best of conventional and complementary treatments for the benefit of their patients. Glasgow Homeopathic Hospital has around 100 admissions each year of people with MS at different stages of the condition and aims at an integrated response to their distress. Different therapeutic modalities are employed, but a homeopathic approach in particular is of benefit in MS. By its nature, it is a whole-person approach and allows for complete individualisation of treatment, taking account of the minutiae of someone's life. This is discussed and some examples of homeopathic treatments, which seem to be more generalisable for commonly encountered MS symptoms, are given.

The difference between adherence to non- nucleoside reverse transcriptase inhibitor (NNRTI) and protease inhibitor (PI)-based regimens was investigated. Better adherence was found in NNRTI-treated patients, especially when efavirenz was included in the regimen, compared with single PI-treated patients and in those with CD4 cell counts less than 200 x 10(6)/l. By contrast, younger age, self-report of active drug use, fatigue or vomiting negatively affected adherence. Self-reported sexual dysfunction was significantly associated with non-adherence only in PI-treated individuals.

In renal failure, severe anemia and associated fatigue, cognitive and sexual dysfunction have a significant impact on the patient's quality of life. Anemia has also been identified as an important etiologic factor in the development of left ventricular hypertrophy. The major cause of anemia in presence of a reduction of glomerular filtration rate is an inadequate production of a glycoprotein hormone, the erythropoietin (EPO). EPO is the primary regulator of the growth and survival of erythroid progenitor. The introduction of recombinant human erythropoietin (rHuEPO) has revolutionized the treatment of anemia in chronic renal failure. The vast majority of patients respond very well to treatment, but 5-10% of patients show some resistance to EPO, the most common cause of which is iron deficiency. Several studies are recently commenced to investigate the effects of preventing renal anemia ever developing. The target of hemoglobin concentration in pre-dialysis and dialysis patients are object of continuous re-examinations.

In a single-blind, placebo-controlled study, the effects of a 3-month oral administration of 160 mg/day testosterone undecanoate (Andriol) on the quality of life of men with testosterone deficiency were evaluated. The subjects included ten men with primary hypogonadism and 29 with andropause with sexual dysfunction as the most common problem. The changes in subjective symptoms were evaluated by the PNUH QoL scoring system and the St. Louis University Questionnaire for androgen deficiency in aging males (ADAM). Digital rectal examination (DRE) was performed and serum testosterone, prostate-specific antigen (PSA) and liver profile were monitored. Testosterone undecanoate treatment (n = 33) significantly improved sexual dysfunction and symptom scores of metabolic, cardiopulmonary, musculoskeletal and gastrointestinal functions compared to baseline and to placebo (n = 6). ADAM score also significantly improved after 3 months of treatment. Serum testosterone was significantly increased compared to pretreatment levels only in the testosterone undecanoate group. In the placebo group, no significant changes compared to baseline were found for testosterone levels and QoL questionnaires. No abnormal findings were detected on DRE or laboratory findings in either group. Adverse events, such as gastrointestinal problems and fatigue, were mild and self-limiting. It is concluded that androgen supplement therapy with oral testosterone undecanoate (Andriol) restores the quality of life through improvement of general body functions in men with testosterone deficiency.
