Pellagra is a systemic disturbance caused by a cellular deficiency of niacin, resulting from inadequate dietary nicotinic acid and/or its precursors, the essential amino-acid tryptophan. In Europe and North America cases of pellagra are rarely encountered, but in some developing countries this disease is frequent, and is the most frequent clinical feature of nutritional deficiency of adult. The principal causes of pellagra are: nutritional niacin deficiency; chronic alcoholism; gastro-intestinal malabsorption; some medications (5-fluoro-uracil, isoniazid, pyrazinamide ehtionamide, 6-mercaptopurine, hydantoins, phenobarbital and chloramphenicol). The diagnosis of pellagra is based on the patient's history and the presence of "3 D syndrome": dermatitis, diarrhea, and dementia. The dermatitis caused by pellagra is a bilaterally symmetrical erythema at the sites of solar exposure. The dermatitis begins in the form of an erythema with acute or intermittent onset gradually changing to an exsudative eruption on the dorsa of the hand, face, neck, and chest with pruritus and burning. Acute dermatitis of pellagra resembles sunburn in the first stages, sometimes with vesicles and bullae. The gastro-intestinal disturbances are: anorexia, nausea, epigastric discomfort and chronic or recurrent diarrhea. Anorexia and malabsorbative diarrhea lead to a state of malnutrition and cachexia. Stools are typically watery, but occasionally can be bloody and mucoid. Neuropsychologic manifestation included photophobia, asthenia, depression, hallucinations, confusions, memory loss and psychosis. As pellagra advances, patient become disoriented, confused and delirious; then stuporous and finally die. Pathological changes in the skin is non-specific, there are no chemical tests available to definitively diagnose pellagra. However low levels of urinary excretion of N-methylnicotinamide and pyridone indicates niacin deficiency. The treatment of pellagra consisted to exogenous administration of niacin or nicotinamide cures. Topical management of skin lesions with emollients may reduce discomfort. The therapy should also include other B vitamins, zinc and magnesium as well as a diet rich in calories. The prevention is based in the nutritional education (food sources of niacin: eggs, bran, peanuts, meat, poultry, fish, red meat, legumes and seeds), and the eviction of alcohol.

The present study aimed at investigating depression specificity and escitalopram medication efficacy in 33 patients with panic attacks (PA). Depression according to BDI was found in 96,4% patients with PA. Most important clinical peculiarities of depression in PA patients were asthenia, somatic preoccupation and anxiety in combinations with mild or severe depressed mood and mild lack of satisfaction. Development and severity of depression were significantly associated with duration and frequency of PA. Escitalopram was prescribed in a dosage of 10 mg/day for 2-months. The drug was shown to have high efficacy in the treatment of depression, high preventive activity for PA as well as good tolerability with rare and mild side effects. The conclusion was made that morbidity of depression and PA and depression specificity in patients with PA may be explained by the common pathophysiological mechanisms. Serotonin dysfunction may be the most important mechanism.

Asthenia in cancer patients is the most frequent symptom and probably one of the most disabling. Its right evaluation is essential to set an adequate therapy program. It is influenced by many factors, like anemia, anxiety and depression, sleep disorders, pain or malnutrition. Asthenia needs a multidisciplinary approach, and the best therapy is over this predisposing factors. Nevertheless, research about its ethiology, epidemiology and therapeutic options needs further studies to clearly define a better way to face this significant and, in so many ways, underestimated aspect of cancer patients. In this paper we review the present state of knowledge about asthenia in cancer patients and future possibilities open to research.

Major depression is a mood disorder characterized by a sense of inadequacy, despondency, decreased activity, pessimism, anhedonia and sadness where these symptoms severely disrupt and adversely affect the person's life, sometimes to such an extent that suicide is attempted or results. Antidepressant drugs are not always effective and some have been accused of causing an increased number of suicides particularly in young people. Magnesium deficiency is well known to produce neuropathologies. Only 16% of the magnesium found in whole wheat remains in refined flour, and magnesium has been removed from most drinking water supplies, setting a stage for human magnesium deficiency. Magnesium ions regulate calcium ion flow in neuronal calcium channels, helping to regulate neuronal nitric oxide production. In magnesium deficiency, neuronal requirements for magnesium may not be met, causing neuronal damage which could manifest as depression. Magnesium treatment is hypothesized to be effective in treating major depression resulting from intraneuronal magnesium deficits. These magnesium ion neuronal deficits may be induced by stress hormones, excessive dietary calcium as well as dietary deficiencies of magnesium. Case histories are presented showing rapid recovery (less than 7 days) from major depression using 125-300 mg of magnesium (as glycinate and taurinate) with each meal and at bedtime. Magnesium was found usually effective for treatment of depression in general use. Related and accompanying mental illnesses in these case histories including traumatic brain injury, headache, suicidal ideation, anxiety, irritability, insomnia, postpartum depression, cocaine, alcohol and tobacco abuse, hypersensitivity to calcium, short-term memory loss and IQ loss were also benefited. Dietary deficiencies of magnesium, coupled with excess calcium and stress may cause many cases of other related symptoms including agitation, anxiety, irritability, confusion, asthenia, sleeplessness, headache, delirium, hallucinations and hyperexcitability, with each of these having been previously documented. The possibility that magnesium deficiency is the cause of most major depression and related mental health problems including IQ loss and addiction is enormously important to public health and is recommended for immediate further study. Fortifying refined grain and drinking water with biologically available magnesium to pre-twentieth century levels is recommended.

The aim of this cross-sectional study was to compare health-related quality of life (HRQOL) of Russian hemodialysis (HD) patients with the general population and international data, and to determine factors influencing HRQOL. One thousand forty-seven HD patients from 6 dialysis centers were studied (576 male, age 43.5 +/- 12.5 years, HD duration 55.0 +/- 47.2 months). Health-related quality of life was evaluated by SF-36. Self-appraisal Depression Scale (W. Zung), State-Trait Anxiety Inventory, and Level of Neurotic Asthenia Scale were used. Hemodialysis patients scored significantly lower than the general Russian population in the majority of SF-36 scales. The only exception was the Mental Health score, which was even better than the general population. The Mean physical component score (PCS) of HD patients was 36.9 +/- 9.7, and the mental component score was (MCS) 44.2 +/- 10.5. In multiple linear regression analysis, increasing age, HD duration, depression level and number of days of hospitalization in the past 6 months were significant independent predictors of low PCS along with a low level of serum albumin. Advancing age was also a predictive factor for low MCS along with increase of HD duration, depression level, trait anxiety, and level of asthenia. As far as we know, this is the first study to report on HRQOL of a large sample of Russian HD patients performed using SF-36. Compared with the general population, Russian HD patients had significantly lower scores on the majority of SF-36 scales, especially in the physical domain. The mean PCS and MCS were comparable with European data for HD patients. A number of demographic, clinical, and psychological variables affect HRQOL.

Rhodiola rosea L., or 'golden root', is a popular plant in traditional medicine in Eastern Europe and Asia, with a reputation for improving depression, enhancing work performance, eliminating fatigue and treating symptoms of asthenia subsequent to intense physical and psychological stress. Due to these therapeutic properties, R. rosea is considered to be one of the most active adaptogenic drugs. To confirm and extend results obtained in the few preclinical and clinical studies available in English language journals, the purpose of the present study was to re-investigate the effects produced by a single oral administration of an R. rosea hydroalcohol extract (containing 3% rosavin and 1% salidroside) on the central nervous system in mice. The extract was tested on antidepressant, adaptogenic, anxiolytic, nociceptive and locomotor activities at doses of 10, 15 and 20 mg/kg, using predictive behavioural tests and animal models. The results show that this R. rosea extract significantly, but not dose-dependently, induced antidepressant-like, adaptogenic, anxiolytic-like and stimulating effects in mice. This study thus provides evidence of the efficacy of R. rosea extracts after a single administration, and confirms many preclinical and clinical studies indicating the adaptogenic and stimulating effects of such R. rosea extracts. Moreover, antidepressant-like and anxiolytic-like activities of R. rosea were shown in mice for the first time.

One of frequent presentations of multiple sclerosis (MS) is chronic fatigue that may be determined as a subjective decrease of the physic and/or psychic energy level. Fatigue can be divided into asthenia (fatigue in resting state), pathological fatigability (exhaustion during physical loading) and fatigue concomitant with other symptoms (MS exacerbation). There are central as well as peripheral mechanisms of fatigue formation. Frequent is a combination of fatigue and affective disorders in MS, in particular depression, as well as sleep disturbances (insomnia, restless legs syndrome) that may indicate the common origin of their mechanisms, i.e. reduction of serotoninergic and noradrenergic systems activity. Endocrinal and autoimmune components are considered as important in fatigue syndrome formation, the latter exerting more influence on asthenia than on pathological fatigability. Further investigation into pathogenetic mechanisms of asthenia (fatigue in resting state), pathological fatigability (fatigue in active state) and specification of their differential diagnostic features allow not only to understand the essence of this syndrome but to choose an adequate individualized therapy.

A frequent manifestation of multiple sclerosis (MS) is chronic fatigue syndrome, which can be defined as a subjective decrease in the level of physical and/or mental energy. Chronic fatigue syndrome can be divided into asthenia (fatigue at rest), pathological fatigability (fatigue on physical loading), and fatigue on the background of deterioration of other symptoms (exacerbation of MS). There are both central and peripheral mechanisms for the formation of fatigue. The combination of fatigue and affective disturbances, especially depression and sleep disorders (insomnia, restless legs syndrome) is common in MS and may provide evidence that they share common mechanisms--decreases in the activity of the serotoninergic and noradrenergic systems. An important component in the formation of chronic fatigue syndrome consists of endocrine and autoimmune factors, the latter having a greater effect on asthenia than on pathological fatigue. Further studies of the pathogenetic mechanisms of the formation of asthenia and pathological fatigue and clarification of their differential diagnostic signs should allow not only a better understanding of the nature of this syndrome, but also better selection of individual treatment.

In-depth clinical psychological investigation of airline pilots with neurocirculatory dystonia (n=194, mean age 38.57 +/- 0.85) and essentially healthy control pilots (n=183, mean age 38.4+/-0.92) revealed distinctive features in NCD pilots' mentality and behavior including personality, interpersonal communication, type of thinking, stress reaction, protection tactics, and mental dysfunctions. Psychic deadaptation such as symptoms of psychic asthenia, paranoia, depression, schizophrenia, and impulsive behavior had a negative effect on the clinical course and led to medical disqualification of 15% of NCD pilots.

The objective of the study was to assess the efficacy and safety of aripiprazole in outpatients with posttraumatic stress disorder (PTSD) on a 12-week, open-label trial. Twenty-two subjects with DSM-IV diagnosis of PTSD participated; 16 were combat veterans. The primary outcome measure was PTSD symptom severity assessed with the Clinician Administered PTSD Scale (CAPS). Secondary outcome measures included the Positive and Negative Symptoms Scale and the Hamilton Depression and Anxiety Scales. All subjects had a CAPS score of > or = 60 at baseline. Lifetime history of psychotic disorders or bipolar illness was exclusionary. The overall analysis across time was Repeated Measures ANOVA, using Bonferroni corrections. Fourteen subjects completed 12 weeks of treatment. Eight subjects dropped-out due to side effects. For patients who discontinued, missing values were estimated using "the last observation carried forward" method. Significant improvements were seen on: CAPS total, all its subscales, positive symptoms, anxiety and depression scores. Fourteen participants were classified as responders, defined by 20% or greater improvement on CAPS total score. Of the 13 subjects who completed final ratings, CAPS total scores improved significantly (P = .011). Two subjects attained remission of PTSD (CAPS < 20), and three had a final CAPS < or = 26. The mean daily dose of aripiprazole was 12.95 mg. The most common side effects were somnolence (54.5%), restlessness (50%), insomnia (36.4%), and asthenia (31.8%). These results indicate that aripiprazole was effective in about two thirds of subjects that tolerated this medication. The initially high dropout rate may be related to intolerability due to a high starting dose (10 mg), suggesting beginning treatment at lower doses. These preliminary results are encouraging; a double blind study seems warranted.
