Field dependent individuals differ psychologically from field independent subjects. They use more primitive defense mechanisms, and are more responsive to social forces around them than field independent subjects. Psychophysiological differences exist between these groups which will be reviewed. Obesity and alcoholism are also related to field dependency, as well as other psychosomatic disorders. Our series of experiments show that field dependent subjects are less left cerebrally dominant, and show most elements (in subclinical form) of a left cerebral lobe (Gerstmann's) syndrome. Implications for psychosomatic medicine are noted in the psychophysiological differences seen.

A family systems model of obesity is developed that attempts to integrate systems epistemology, Minuchin's work on psychosomatic disorders, and a review of the literature on obesity. The model presents obesity as being inextricably embedded in relationship patterns that fundamentally influence its etiology and maintenance. It is argued that the emergent properties of these relationships need to be the focus of analysis, rather than the elementary components residing within the individual, which are emphasized in traditional theories of obesity. The radical shift involved in moving from the traditional mechanistic models to a systems perspective is also discussed because these approaches are based on different epistemologies. The fundamental differences between these epistemologies are important and often underemphasized, which has led to much confusion in past research. Based on the model developed here and supportive data from the obesity literature, the conclusion is reached that obesity research and treatment are likely to be advanced by adopting a systemic approach.

Alexithymia is a concept created by Sifneos and characterized by an inability to find words to describe feelings or emotions. The phenomenon seems to be also related to a poverty of cognitive and symbolic processes (de Bonis, 1986). Alexithymia was first studied in psychosomatic disorders, then in several other somatic disorders as chronic bronchitis, chronic pain, obesity, abuse disorders. It also appears in non medically ill subjects. The french validation of the Toronto alexithymia Scale (TAS) in general population (n = 786) has shown 8.14% alexithymia frequency. The TAS is a 26-items self-report measure rated on a five-point likert scale. In the study we use the TAS and we refer to a visual test: the Parallel Visual Information Processing Test (PVIPT), involving the connexionist theory in the neuropsychological approach of alexithymia. The neuropsychological model is based on cerebral hemispheric specialization: emotions are localized in the right hemisphere and verbal expression depends on the left hemisphere in right-handed persons. The model posits that alexithymia is related to a lack of connection between the two cerebral hemispheres. It explains the deficit to verbally articulate emotions. The aim of our study is to compare the quality of cognitive and symbolic process (PVIPT) in alexithymic and non alexithymic subjects in general population. 773 students are tested with the TAS. We find 47 alexithymic subjects (6.08%). 22 alexithymic subjects and the control group (35 non alexithymic subjects) are evaluated with the PVIPT. Results are coherent with our previous studies on alexithymia in somatic disorders on one hand and alexithymia in neurological disease on the other hand. Theorical model, clinical observation and experimental results tend to define congruent hypothesis relative to the anxious pathology, supporting the reflexion and the research in the domain of the emotional disorders.

The involvement of cellular immunity in the burnout syndrome remains to be elucidated. We assessed three components of burnout of the Maslach Burnout Inventory: emotional exhaustion; depersonalization (DP); and personal accomplishment, as well as natural killer cell activity (NKCA) and NK cell subsets in 42 male workers. Workers with a higher DP score showed a lower NKCA and a lower proportionality of CD57+CD16+ to total lymphocytes. There were no differences in any of the health behaviors (e.g., smoking, alcohol, or obesity) between workers showing higher burnout and those showing lower burnout. A stepwise multiple regressions analysis demonstrated that NKCA was closely correlated with DP, independent of other variables, including a stress index. These results suggest that the relationship between reduced cellular immunity and DP is not due to traditional work stress or health behavioral problems. Further studies on DP as a psychosomatic disorder as well as an occupational health problem should be performed in the future.

It is well known that the nutritional deficiency possibly causes cardiac dysfunction. Although social hygiene has successfully diminished these cardiac dysfunction in developed countries, patients could be found in certain number under altered clinical profiles than before. Excess intake of carbohydrate drinks and carbohydrates should make beri-beri heart in youth. Not only deficiency but recent dietary habits of excessive nutrition in these developed countries are causing new types of nutritional cardiac dysfunctions such as obesity cardiomyopathy in morbid obese. On the other hand, anorexia nervosa which sometimes shows heart failure and sudden death combines with psychosomatic disorders. In this article, the pathogenesis and treatments are discussed focusing on these three cardiac disorders.

Studies which evaluate the psychosocial development and integration of adult female congenital adrenal hyperplasia (CAH) patients are rare but show that patients with the salt wasting form are significantly more virilized and more frequently single and childless. Major complaints are irregular menstruation, hirsutism, acne, obesity, deep voice, and cushingoid features. Surprisingly, a higher prevalence of psychosomatic disorders has not yet been described. Since anorexia nervosa (AN) has not yet been described in patients with CAH, we here report 4 cases of female CAH patients who developed AN during adolescence. Diagnosis of CAH was made between the age of 10 days and 3 years. Three patients suffer from the simple-virilizing form of CAH, one patient has a mild salt wasting CAH. Genital malformation varied from Prader stage II to IV. All 4 patients were compound heterozygotes for mutations/deletions of the CYP21B gene. Control of substitution therapy consisting of hydrocortisone and fluorocortisone was good. AN developed at ages 12, 13, 17, and 21 years (ICD 10 criteria for AN are BMI below 17.5 kg/m2, deliberate weight loss, body image disturbance, and primary or secondary amenorrhoea). Diagnosis of AN was established by psychiatrists and/or psychologists. All four patients showed an impressive and deliberate weight loss between 13 and 20 kg within 6 months, had primary or secondary amenorrhoea, and presented with BMI between 13 and 17.9 kg/m2. All patients received psychological treatment and recovered. However, one patient had a severe relapse of AN. Two patients are now married and one has a healthy son. These cases demonstrate that the diagnosis of CAH is compatible with the development of AN and illustrate the importance of providing treatment for CAH patients that encompasses not only medical but also psychological and social care.

A wide variety of stresses are prevalent in the environment that could change the course and phenotypic expression of metabolic diseases. Amongst the various stresses the oxidative stress plays a pivotal role in the disease progression through free radical generation and may lead to various metabolic disorders such as non-insulin dependent diabetes mellitus, cardiovascular diseases, hypertension obesity, stroke, etc. Psychological stress has been implicated as a root cause of several psychosomatic disorders. Thus there cannot be a life without stress. Under such a scenario of stressful conditions further fueled by life style changes we propose to counteract any kind of stress by another milder form of stress that is likely to protect the cells from drastic effects of severe stress. Here we hypothesize that the beta-cells of islets of Langerhans can be protected from the diabetogenic insults and oxidative stress by inducing a protective stress response such as heat shock through dietary interventions.

Psychological stress has been implicated as a cause of several psychosomatic disorders, but also as a factor that can unfavourably influence many diseases including diabetes mellitus. Measure of psychological stress in diabetes was performed by Psychological Stress Measure (PSM), a validated instrument, designed using 49 items drawn from descriptors generated by focus groups on stress. Clinical and psychological framework was assessed in a cohort of 100 type 2 diabetic patients (30 m, 70 f), aged 66.99 +/- 13.68 years considering disease grade, complications and level of instruction. Three other questionnaires were administered concurrently to all patients: Sickness Impact Profile (SIP), Functional Living Index (FLI) and SF-36 QOL. ANOVA statistical testing and Spearman correlation matrix were used also vs socio-cultural and clinical profile. Gender, obesity, diet compliance, smoking do not affect PSM response. Hypertensive patients and those with family history of diabetes show lower PSM scores, according to a sort of moderator effect on stress of concurrent and/or previous experience with chronic disease. Neuromuscular ailments are more prevalent in women; men vs women experience severe limitations of their working capacities and relational possibilities, with severe discomfort. In the whole, higher scores of PSM (greater stress p < 0.01) and lower scores of FLI (fair well-being perception; p < 0.01) are reciprocally related inside any school instruction level. Despite the great reciprocal association of the PSM vs FLI and SIP, no significant correlation is found between PSM vs SF-36 QOL. Socio-cultural elements interfere, and particularly instruction level quantified as school grades achieved, with the manner of living their disease. Interventions on psychological distress of type 2 diabetes mellitus patients is warranted, specially in the groups with lower levels of instruction which may need an attentive strategy for achieving a satisfactory coping with this disease.

Obesity is associated with disturbed cardiovascular responsivity to mental stress, which may mediate psychosocial disease pathways. Whether being aerobically fit is protective against psychophysiological dysfunction in the presence of overweight or obesity is undetermined. Peripheral blood flow, blood pressure, and cardiac responses were measured during a 2-min mental stress task in 48 healthy men (aged 18-32 years). Mental stress-evoked increases in mean arterial pressure and heart rate, forearm vasodilatation, and cardiac parasympathetic withdrawal. Multiple linear regression analyses adjusted for age, peak oxygen uptake, and baseline forearm vascular resistance, revealed that greater fatness was related to a blunted vasodilatation response to mental stress (beta=-.31, p<.05). There were no interactive effects of fitness and fatness. Fitness does not appear to moderate the association between fatness and impaired vascular stress responsivity in normal and overweight men.

Obesity is a psychosomatic illness; treating the emotional illness first gives a much better chance of success in weight reduction. In this study, older, fatter, calmer and happier, more realistic patients with fewer associated illnesses did best of all (37 lb. weight loss).
