An appreciative cooperation among dermatology, clinical psychology and psychology and psychiatry is necessary and useful. By selected facts interactions between central and autonomous nervous system on one side and the immune system on the other side were described. As far as the neutrocutaneous interrelations are concerned the cutaneous stimulation appears to be an important factor for the physical and physiologic development. In addition, the skin communicates to the environment and other people. Therefore, it plays a role in the social integration. Psychiatric diseases can affect the skin (e.g. delusions of parasitosis in schizophrenia). On the other hand primary skin diseases such as psoriasis, atopic dermatitis, acune vulgaris, chronic idiopathic urticaria and alopecia areata may induce psychologic features. The characteristics of the personalities of dermatological patients are discussed. The psychodiagnostics (personal interview, questionaires) is followed by psychotherapeutic procedures such as personal consultations, treatment in groups, hypnosis and autogenous training. Our experiences in the psychodiagnostics and treatment are briefly reported. Finally, psychotropic drugs-antipsychotic, anti-depressant, antianxiety, and hypnotic agents - may be useful as an adjunct in the management of dermatologic disorders, if applied under precautious indications.

This paper presents epidemiological data on the prevalence of 26 common (i.e., having a lifetime prevalence of more than 1 per 10(4) individuals in the population) multifactorial diseases in Hungary and estimates of detriment associated with them. The detriment is expressed using 3 indicators, namely years of lost life (LL), potentially impaired life (PIL) and actually impaired life (AIL). The total prevalence of these diseases in Hungary has been estimated to be about 6500 per 10(4) individuals in the population. This estimate is in agreement with published data for other parts of the world. On the basis of clinical severity, these diseases have been split into 3 groups, namely (1) very severe (schizophrenia, multiple sclerosis, epilepsy, acute myocardial infarction and related conditions, and systemic lupus erythematosus); (2) moderately severe and/or episodal or seasonal (15 entities including Graves' disease, diabetes mellitus, gout, affective psychoses, essential hypertension, peptic ulcers, asthma, etc.); and (3) less severe than those in the first 2 groups (varicose veins, allergic rhinitis, atopic dermatitis, Scheuermann disease and adolescent idiopathic scoliosis). The essential clinical and genetic aspects of these diseases are briefly discussed. With the exception of epilepsy, none of the diseases included in our list causes mortality between ages 0 and 19. However, they are among the leading causes of death between ages 20 and 69 and thereafter. A sizeable proportion of those with essential hypertension, diabetes mellitus, rheumatoid arthritis, etc. survive to 70 years and beyond, as do those with gout, glaucoma, allergic rhinitis, psoriasis, etc. Overall, about 16% of all deaths that occur in Hungary every year (all age groups) can be attributed to these diseases. The mean number of years of PIL covers a wide range (about 20-40, 12-70 and 40-60 for groups 1, 2 and 3, respectively), the overall mean being about 24 years. However, the nature and degree of impairment and the impact on the life quality of those afflicted differ for the different diseases. Likewise, the mean number of years of AIL (for which the interval between the mean age at premature retirement and mean age at death was used as a rough index) also spans a wide range from 16 to 45, and the overall mean is about 20 years. At the population level, the diseases considered in this paper cause about 2700 years of LL, 96,000 years of PIL and about 5800 years of AIL per 10(4) individuals in the population. Relative to Mendelian diseases as a whole, these multifactorial diseases are associated with much greater detriment (LL: 1.4 X; PIL: 30 X and AIL: 3.9 X).

Essential polyunsaturated fatty acids (PUFA) cannot be synthesised in the body and must be ingested by food. A balanced intake of both n-6 and n-3 PUFA is essential for good health. PUFA are the basic constituents of phospholipid membranes and determine cellular membrane fluidity and modulate enzyme activities, carriers and membrane receptors. They are also precursors of active metabolites known collectively as eicosanoids (prostaglandins, prostacyclins, thromboxanes and leukotrienes) which regulate our cellular functions. Studies indicate that n-3 PUFA have anti-inflammatory, antithrombotic, antiarrhythmic actions and immuno-modulating properties. Erythrocyte fatty acid status is a reflection of dietary fat intake. It also explores PUFA metabolism and gives information about the integration of these fatty acids into cellular membranes. Thus, erythrocyte fatty acid analysis can detect PUFA insufficiencies and imbalances from the diet, but also metabolic abnormalities and lipid peroxidation. It can be helpful in the prevention and the control of chronic diseases in which PUFA alterations have been observed as coronary heart diseases, hypertension, cancer, diabetes, inflammatory and auto-immune disorders, atopic eczema, Alzheimer dementia, major depression, schizophrenia, multiple sclerosis, etc.

An analysis of comorbidity of psychiatric and dermatological pathology in historical, epidemiological and clinical aspects is presented. Psychocutaneous disorders (delusional parasitosis, hypochondria circumscripta, obsessive-compulsive disorders with self-mutilations, pathomimia) play a central role in systematics elaborated in the present study. The authors suggest that delusional parasitosis is a subtype of paranoiac psychosis (paranoia, paranoiac schizophrenia). Psychiatric disorders triggered by dermatological pathology were specified as nosogenous reactions, depressive reactions with sociophobia, pathologic personality development (paranoiac, sensitive, hypochondriac). Atopic dermatitis, eczema, urticaria, psoriasis, herpes simplex, alopecia areata, rosacea, etc, are regarded among dermatological psychosomatic disorders with psychogenic manifestation/exacerbation.

Angiotensin-II, a product of angiotensin converting enzyme (ACE) action, regulates vascular tone, stimulates the release of pro-inflammatory cytokines, activates NFkappaB, increases oxidant stress, and suppresses nitric oxide synthesis. Thus, angiotensin-II is pro-inflammatory in nature. Hence, increase in ACE activity and the concentrations of angiotensin-II initiate and perpetuate inflammation. Since ACE is present in many tissues including: the uterus, placenta, vascular tissue, heart, brain, adrenal cortex and kidney, leukocytes, alveolar macrophages, peripheral monocytes, neuronal cells and epididymal cells, this suggests that angiotensin-II may have a role in atherosclerosis, congestive cardiac failure, stroke, bipolar disorder, schizophrenia, dementia, Alzheimer's disease, psoriasis, atopic and non-atopic dermatitis, eczema, several acute and chronic inflammatory diseases, and cancer, conditions in which inflammation is known to play a significant role. This suggests that ACE inhibitors and/or angiotensin-II receptor blockers could be of significant benefit in the management of these conditions. Alternatively, structural analogues of presently available ACE inhibitors and angiotensin-II receptor blockers could be developed such that they are not only useful in the treatment of hypertension and CHF but also possess anti-inflammatory actions.

Angiotensin-II regulates vascular tone, stimulates the release of pro-inflammatory cytokines, activates NF-kappaB, increases oxidant stress, and suppresses nitric oxide synthesis, and thus, it functions as an inflammatory molecule. Since ACE is present in many tissues, this suggests that angiotensin-II may play a significant role in atherosclerosis, congestive cardiac failure, stroke, bipolar disorder, schizophrenia, dementia, Alzheimer's disease, psoriasis, atopic and non-atopic dermatitis, eczema, several acute and chronic inflammatory diseases, and cancer, conditions in which inflammation is an aetiopathogenic factor. Thus, ACE inhibitors and/or angiotensin-II receptor blockers could be of benefit in these conditions. Furthermore, structural analogues of ACE inhibitors and angiotensin-II receptor blockers could be developed that possess anti-inflammatory actions without significant action on the cardiovascular system.

Cytokine regulation disturbances have a significant role in the pathogenesis of psychiatric disorders, schizophrenia and depression, as well as in dermatologic disorders. Probably it is one of the reasons of the co-occurrence of these two kinds of disorders. Two cases of psychiatric and dermatologic disorders occurring together are presented in this paper. In the first case study depression was associated with atopic dermatitis, in the second case the delusion disorder was described with secondary dermatologic sequellae. In both cases, after psychopharmacotherapy, the improvement of the psychic state was correlated with the relief or regression of skin symptoms.

Chronic itch is known to have psychogenic elements; however, there is no data on itch prevalence and characteristics among hospitalized psychiatric patients. We investigated the prevalence and types of itching among hospitalized psychiatric patients who met DSM-IV criteria for schizophrenia, affective or other psychiatric disorders. A validated itch questionnaire based on the McGill Pain Questionnaire, which examines the incidence and characteristics of itching, was administered to 111 patients, hospitalized in an Israeli university hospital. Patients with atopic eczema, psoriasis, or systemic diseases that cause pruritus were excluded. Thirty-six patients (32% of those screened) reported itching. Few sought help or used anti-pruritic therapy. Itching should be addressed during psychiatric assessments, in order to provide appropriate treatment.

Schisandra chinensis (Turcz.) Bail. is often referred to as an example of a medicinal plant with use in modern Chinese medicine. However, Schisandra chinensis first gained recognition as an adaptogen in the official medicine of the USSR in the early 1960s, principally as a result of the large number of pharmacological and clinical studies carried out by Russian scientists in the preceding two decades. Schizandra has now secured an established position within the medicine of Russia/USSR as evidenced by the inclusion of the drug in recent editions of the National Pharmacopoeia of the USSR and in the State Register of Drugs. Pharmacological studies on animals have shown that Schizandra increases physical working capacity and affords a stress-protective effect against a broad spectrum of harmful factors including heat shock, skin burn, cooling, frostbite, immobilisation, swimming under load in an atmosphere with decreased air pressure, aseptic inflammation, irradiation, and heavy metal intoxication. The phytoadaptogen exerts an effect on the central nervous, sympathetic, endocrine, immune, respiratory, cardiovascular, gastrointestinal systems, on the development of experimental atherosclerosis, on blood sugar and acid-base balance, and on uterus myotonic activity. Studies on isolated organs, tissues, cells and enzymes have revealed that Schizandra preparations exhibit strong antioxidant activities and affect smooth muscles, arachidonic acid release, biosynthesis of leukotriene B(4) in leukocytes, platelet activating factor activity, carbohydrate-phosphorus metabolism, the formation of heat shock protein and polyamines, tissue respiration and oxygen consumption, and the tolerance of an organism to oxygen intoxication. In healthy subjects, Schizandra increases endurance and accuracy of movement, mental performance and working capacity, and generates alterations in the basal levels of nitric oxide and cortisol in blood and saliva with subsequent effects on the blood cells, vessels and CNS. Numerous clinical trials have demonstrated the efficiency of Schizandra in asthenia, neuralgic and psychiatric (neurosis, psychogenic depression, astheno-depressive states, schizophrenia and alcoholism) disorders, in impaired visual function, hypotension and cardiotonic disorders, in epidemic waves of influenza, in chronic sinusitis, otitis, neuritis and otosclerosis, in pneumonia, radioprotection of the fetoplacental system of pregnant women, allergic dermatitis, acute gastrointestinal diseases, gastric hyper- and hypo-secretion, chronic gastritis, stomach and duodenal ulcers, wound healing and trophic ulcers. This review describes the considerable diversity of pharmacological effects of Schisandra chinensis reported in numerous studies carried out in the former USSR and which have been confirmed over more than 40 years of use of the plant as an official medicinal remedy. Such knowledge can be applied in the expansion of the use of Schizandra in the pharmacotherapy of European and other countries as well as for the further discovery of new drugs based on the lignans that constitute the main secondary metabolites of this plant.

Reporting bias represents a major problem in the assessment of health care interventions. Several prominent cases have been described in the literature, for example, in the reporting of trials of antidepressants, Class I anti-arrhythmic drugs, and selective COX-2 inhibitors. The aim of this narrative review is to gain an overview of reporting bias in the medical literature, focussing on publication bias and selective outcome reporting. We explore whether these types of bias have been shown in areas beyond the well-known cases noted above, in order to gain an impression of how widespread the problem is. For this purpose, we screened relevant articles on reporting bias that had previously been obtained by the German Institute for Quality and Efficiency in Health Care in the context of its health technology assessment reports and other research work, together with the reference lists of these articles.We identified reporting bias in 40 indications comprising around 50 different pharmacological, surgical (e.g. vacuum-assisted closure therapy), diagnostic (e.g. ultrasound), and preventive (e.g. cancer vaccines) interventions. Regarding pharmacological interventions, cases of reporting bias were, for example, identified in the treatment of the following conditions: depression, bipolar disorder, schizophrenia, anxiety disorder, attention-deficit hyperactivity disorder, Alzheimer's disease, pain, migraine, cardiovascular disease, gastric ulcers, irritable bowel syndrome, urinary incontinence, atopic dermatitis, diabetes mellitus type 2, hypercholesterolaemia, thyroid disorders, menopausal symptoms, various types of cancer (e.g. ovarian cancer and melanoma), various types of infections (e.g. HIV, influenza and Hepatitis B), and acute trauma. Many cases involved the withholding of study data by manufacturers and regulatory agencies or the active attempt by manufacturers to suppress publication. The ascertained effects of reporting bias included the overestimation of efficacy and the underestimation of safety risks of interventions.In conclusion, reporting bias is a widespread phenomenon in the medical literature. Mandatory prospective registration of trials and public access to study data via results databases need to be introduced on a worldwide scale. This will allow for an independent review of research data, help fulfil ethical obligations towards patients, and ensure a basis for fully-informed decision making in the health care system.
