[Practical examinations for neurology. The Tuebingen model].
Practically orientated examinations represent an important innovation in medical education. In the subject area of neurology, the "Objective Structured Clinical Examination" (OSCE) proved to be a viable form of examination for the subject of neurological anamnesis and a medical examination course at the University of Tuebingen in Germany. A total of 577 students in their sixth semester of study were examined in, to date, four OSCEs and achieved an average of 17.5 of possible 25 points in the subject of neurology. Improvement in point average was observable over the course of time, while the average performance of students across the total OSCE remained constant. Student evaluations regarding form and content of the neurological examinations yielded an average grade of B (in the German system 2.1). Simulation patients were rated with an average grade of A- (German system 1.7). Examination methods are presented together with experience concerning preparation, implementation, and developmental enhancement of neurological OSCE examinations. Implications of this novel form of examination for faculty development and regulating students' learning and study behaviour are discussed.

[Obesity--an interdisciplinary task].
In industrial nations, over the last five decades conditions concerning nutrition and physical exercise as well as socio-economic circumstances have changed radically. One of the consequences following from this development has been a rapid increase in the prevalence of obesity. Studies have shown that currently 20 percent of the German adult population suffer from obesity. Investigations into the etiology of obesity have to address complex interactions between genetic, socio-economic and psychosocial factors. A year ago, at the University Hospital Tübingen different departments joined to set up the "Plattform Adipositas". Endocrinologists, obesity surgeons, professionals in sports medicine and psychosomatic medicine as well as dieticians are collaborating to develop scientifically based therapy programs and treatment pathways for obese patients. The following article gives an account of this exemplary interdisciplinary cooperation.

[Anorexia nervosa].
Anorexia nervosa differs distinctly from other psychogenic eating disorders. Well known for the past 300 years, anorexia occurs consistently and is one of the most serious illnesses to be found for a certain age group. Three-quarters of the patients are healed or improve their condition long-term; one-quarter has a chronic course frequently including somatic complications and death. Because of the long healing process as well as the extensive chronification and complication rate, an individual treatment plan should be set up at the beginning of therapy to allow for a long-term structure of the course of therapy. Depending on the severity, phase and co-morbidity, inpatient and ambulant therapies are indicated. Depending on the duration of therapy, adequate weight (BMI > 15 kg/m2), good motivation, and lack of complications, an ambulant therapy is justified. Inpatient treatment is multimodal corresponding to the multifactorial etiology of anorexia nervosa. Weight gain is an important primary goal of therapy and a prerequisite for a conflict oriented, ambulant psychotherapy to be carried on after inpatient treatment. Ambivalent psychotherapy motivation and the necessity of symptom orientation demand technical modification both for inpatient as well as ambulant psychotherapy.

[Family therapy within the treatment of eating disorders].
The families of patients suffering from eating disorders such as Anorexia nervosa (AN) und Bulimia nervosa (BN) are, owing to the illness, subject to considerable emotional strain and are furthermore often characterised by significant structures and patterns of interaction within the family. Consequently the inclusion of patients' family members, whose status can be seen as increasingly gaining in scientific approval, plays an important role within both diagnosis and therapy. Of particular importance is the medical informative discussion with both patients and their parents which takes place in a primarily medical context and aims to develop and increase therapy motivation. For this purpose the doctor should possess basic knowledge concerning dialogue management with families, as will be presented in the current article. Within further stages of the therapeutic process the spectrum of interventions at the level of the family ranges from educational and supportive measures to family therapy in a more narrow sense, which is carried out by specialist psychotherapists either as outpatient-treatment or within the framework of therapy with inpatients of a clinic.

Cardiac parasympathetic regulation in obese women with binge eating disorder.
OBJECTIVE: Obese individuals with a binge eating disorder (BED) differ from obese non-binge eaters (NBED) with respect to (a) eating behaviour, (b) psychiatric comorbidity and (c) level of psychosocial distress. The aim of the study was to explore whether these three factors have an influence on cardiac parasympathetic function, that is independent of obesity: as alterations in cardiac parasympathetic function may have a role in the higher cardiovascular mortality that is present in obese individuals. METHODS: In total, 38 obese women (BMI>30 kg/m(2)), with a BED and 34 age and BMI matched healthy controls (NBED) completed a laboratory stress protocol that incorporated a baseline resting period, Head-up Tilt Testing (HUT) and two challenging mental tasks. Heart rate and blood pressure were measured continuously during the protocol. Parasympathetic cardiac regulation was assessed as the high frequency component of heart rate variability (HRV-HF). RESULTS: Mental challenge led to an augmented reduction of HRV-HF in obese binge eaters, which was linked to the binge eating frequency and hunger perception, but not to psychiatric comorbidity. During baseline conditions and HUT, no significant differences in parasympathetic measures were observed between the two subject groups. CONCLUSION: Subjects with a BED showed greater reduction in parasympathetic cardiac control (HRV-HF) during mental stress, suggesting higher stress vulnerability in women with a BED. Longitudinal investigations are necessary to evaluate whether this is associated with an increased cardiovascular mortality.

Acupuncture treatment in irritable bowel syndrome.
BACKGROUND AND AIMS: Despite occasional positive reports on the efficacy of acupuncture (AC) on functions of the gastrointestinal tract, there is no conclusive evidence that AC is effective in the treatment of irritable bowel syndrome (IBS). PATIENTS AND METHODS: Forty three patients with IBS according to the Rome II criteria were randomly assigned to receive either AC (n = 22) or sham acupuncture (SAC) (n = 21) using the so-called "Streitberger needle". Treatment duration was 10 sessions with an average of two AC sessions per week. The primary end point was improvement in quality of life (QOL) using the functional digestive diseases quality of life questionnaire (FDDQL) and a general quality of life questionnaire (SF-36), compared with baseline assessments. QOL measurements were repeated three months after treatment. RESULTS: Both the AC and SAC groups improved significantly in global QOL, as assessed by the FDDQL, at the end of treatment (p = 0.022), with no differences between the groups. SF-36 was insensitive to these changes (except for pain). This effect was partially reversed three months later. Post hoc comparison of responders and non-responders in both groups combined revealed a significant prediction of the placebo response by two subscales of the FDDQL (sleep, coping) (F = 6.746, p = 0.003) in a stepwise regression model. CONCLUSIONS: Acupuncture in IBS is primarily a placebo response. Based on the small differences found between the AC and SAC groups, a study including 566 patients would be necessary to prove the efficacy of AC over SAC. The placebo response may be predicted by high coping capacity and low sleep quality in individual patients.

[Stress and autonomic dysregulation in patients with fibromyalgia syndrome].
AIM: The aim of the present study was to evaluate to what extent the orthostatic dysregulation of FMS patients can be attributed primarily to reduced baroreceptor-mediated activation of the sympathetic nervous system and whether a hyporeactive sympathetic nervous system can also be confirmed for mental stress. PATIENTS AND METHODS: A total of 28 patients with primary FMS were examined and compared with 15 healthy subjects. Diagnostic investigations of the autonomic nervous system were based on measuring HRV in frequency range and assessing spontaneous baroreflex sensitivity (sBRS) under mental stress and passive orthostatism. RESULTS: Both under orthostatic and mental stress FMS patients exhibited reduced activation of the sympathetic nervous system as measured by the spectral power of HRV in the low-frequency range and the mean arterial blood pressure or heart rate. The present study provided no indications for dysregulation of sBRS. CONCLUSION: The results obtained confirm the hypothesis of a hyporeactive stress system in FMS patients for both peripherally and centrally mediated stimulation of the sympathetic nervous system.

Prognostic value of duration of illness and early intervention in bulimia nervosa: a systematic review of the outcome literature.
OBJECTIVE: Early intervention is often regarded as an important step for the prevention of a chronic eating disorder. The primary aim of this review was to systematically evaluate the outcome literature and to better describe the effects of early intervention on the course of bulimia nervosa. METHOD: Twenty-four follow-up studies were subjected to nine "best-evidence" criteria for methodological soundness. Of these 24 studies, 5 met all methodological criteria and were considered in more detail. RESULTS: Only one of these five studies found a significant association between duration of illness and outcome. These studies were re-examined to exclude studies that included patients who were not first admissions in order to distinguish between the effect of duration of illness versus early intervention. This re-examination excluded four of the five studies, and the remaining study provided no data regarding prior treatment. DISCUSSION: Based on this selection of studies, it was concluded that there is no consistent evidence to support that early intervention necessarily implies a better long-term outcome. Due to the multiple methodological problems that plague follow-up studies, future research would be improved by employing designs that directly test the impact of early versus late intervention.

Altered energy metabolism in anorexia nervosa.
Optimal nutritional rehabilitation of anorexia nervosa requires more information concerning actual energy and substrate requirements. To this end, indirect calorimetry was performed in female patients (n=34, age 20.9+/-1.2 yr, body mass index [BMI] 15.6+/-0.2 kg/m(2); mean+/-SEM) soon after commencement of refeeding and at the time of discharge from hospital (n=18, BMI 19.0+/-0.3 kg/m(2)). Healthy female controls (n=18, age 24.6+/-1.3 yr, BMI 21.6+/-0.6 kg/m(2)) were also tested. Resting energy expenditure (REE) and respiratory quotient (RQ) were measured in the fasting state, followed by diet-induced thermogenesis (DIT) and RQ over a 4 h period following a 100 g oral glucose load. Compared with post-refeeding patients and controls, pre-refeeding patients had a high basal RQ and a low REE, with a paradoxically higher DIT (13.2+/-0.9% of REE vs. 8.3+/-1.2% and 8.6+/-0.9% in post-refeeding patients and controls, respectively). RQ values in pre-refeeding patients exceeded unity following the glucose load, probably reflecting net lipogenesis, whereas in the post-refeeding patients, post-glucose RQ was similar to that of controls, suggesting premature curtailment of lipogenesis. These data demonstrate energy wasting in emaciated patients with anorexia nervosa. Biological repair processes could account for disproportionate energy loss early in refeeding and there may be some later impediment to full restoration of fat stores.

Long-term outcome of anorexia nervosa in a prospective 21-year follow-up study.
BACKGROUND: Given our poor understanding of the very long-term course of anorexia nervosa. many questions remain regarding the potential for recovery and relapse. The purpose of the present study was to investigate long-term outcome and prognosis in an anorexic sample 21 years after the initial treatment. METHOD: A multidimensional and prospective design was used to assess outcome in 84 patients 9 years after a previous follow-up and 21 years after admission. Among the 70 living patients, the follow-up rate was 90%. Causes of death for the deceased patients were obtained through the attending physician. Predictors of a poor outcome at the 21-year follow-up were selected based on the results of a previous 12-year follow-up of these patients. RESULTS: Fifty-one per cent of the patients were found to be fully recovered at follow-up, 21% were partially recovered and 10% still met full diagnostic criteria for anorexia nervosa. Sixteen per cent were deceased, due to causes related to anorexia nervosa. The standardized mortality rate was 9.8. The three groups also showed significant differences in psychosocial outcome. A low body mass index and a greater severity of social and psychological problems were identified as predictors of a poor outcome. CONCLUSIONS: Recovery is still possible for anorexic patients after a period of 21 years. On the other hand, patients can relapse, becoming symptomatic again despite previously achieving recovery status. Only a few patients classified as having a poor outcome were found to seek any form of treatment, therefore, it is recommended that these patients should be monitored regularly and offered treatment whenever possible.

Osteoporosis in eating disorders: a follow-up study of patients with anorexia and bulimia nervosa.
This study prospectively investigated the course of bone mineral density (BMD) in patients with anorexia nervosa (AN) and bulimia nervosa (BN) over a 3.6-yr follow-up period. From an initial sample of 47 female patients with an eating disorder (T1), 38 (n = 24 AN; n = 14 BN) were reassessed at follow-up (T2) (participation rate, 80.1%). For nonrecovered AN patients at T2, prevalence rates of osteopenia (-1.0 SD > or = T-score > -2.5 SD) and osteoporosis (T-score < or = -2.5 SD) at the lumbar spine were 54.2 and 20.8%, respectively. Due to an annual loss of lumbar spine BMD (-3.7 +/- 4.9%) in the chronic AN patients and a slight but insignificant annual increase (0.7 +/- 1.7%) for those who recovered, the difference in BMD between both outcome groups was more pronounced at follow-up (0.93 +/- 0.13 vs. 1.14 +/- 0.13 g/cm2; P < 0.01). Nonrecovered AN patients with binge eating/purging type showed a significantly reduced BMD compared with patients with the restricting type (0.87 +/- 0.13 vs. 1.02 +/- 0.08 g/cm2; P = 0.02). Both at baseline and follow-up, AN patients had increased rates of bone resorption, as measured by urinary desoxypyridinoline, compared with a control group (n = 42) (11.4 +/- 4.4 vs. 10.4 +/- 7.8, P < 0.001, vs. 5.6 +/- 2.4 and 10.4 +/- 7.8 nM/mM creatinine, P < 0.05, respectively). The subtype of AN and body mass index were best predictors for BMD at the lumbar spine at follow-up (R2 = 0.576). With one exception, all bulimic patients had BMD and markers of bone turnover within the normal range. These results suggest that patients with chronic AN, particularly of the binge eating/purging type, are at high risk for osteoporosis and may need additional therapy to prevent bone loss.

Long-term prognosis in anorexia nervosa: lessons from a 21-year follow-up study.
In a prospective long-term follow-up of 84 patients 21 years after first hospitalisation for anorexia nervosa, we found that 50.6% had achieved a full recovery, 10.4% still met full diagnostic criteria for anorexia nervosa, and 15.6% had died from causes related to anorexia nervosa. Predictors of outcome included physical, social, and psychological variables.

[Eating behavior, eating disorders and obesity].
Over the last 50 years, the nutritional and socioeconomic conditions have dramatically changed in all industrialized countries. As a consequence, there has been a sharp rise in the prevalence of obesity. Simultaneously, social and cultural pressures to maintain a thin body shape have significantly increased. This untoward situation is largely responsible for the steady increase of eating disorders, especially bulimia nervosa and binge-eating disorder, which are common disorders among normal or overweight individuals. Although the criteria for bulimia nervosa were first described in the DSM-III in 1980 (APA, 1980), recent studies have demonstrated that only about 12% of these patients are detected by their GP's. One reason for this low rate of detection may be due to the tendency of patients to conceal their illness from others. It is also possible, however, that general practitioners lack sufficient knowledge about bulimia nervosa, preventing proper identification. To help improve this situation, diagnostic guidelines and therapeutic options were summarized. Binge-eating disorder (BED), which is classified as an "eating disorder not otherwise specified" in the DSM-IV (APA, 1994), has been described as the most relevant eating disorder for overweight individuals. It has been estimated that approximately 20-30% of overweight persons seeking help at weight loss programs are classified as binge eaters. Initial results from these studies suggest that binge eaters may require a modified psychotherapeutic approach which focuses on normalizing disordered eating patterns before attempting weight loss. In addition to the importance of screening for eating disorder behaviors, overweight patients should be assessed for other comorbid conditions, such as depression and anxiety. Further, body image disturbances should be assessed during the evaluation. In the event that comorbid disorders are present, it is recommended that specific psychotherapeutic interventions which target these problems be integrated into the overall weight reduction program.

[Quality of life, depression and coping behavior in patients awaiting heart transplant].
From a medical perspective, heart transplantation is now an established procedure for the treatment of patients with terminal heart failure. For the patient involved, it presents itself as a situation of great psychological distress, particularly during the waiting period. In the last few years, this situation has grown worse due to the decline in the number of donor organs and the resulting longer waiting period. The aim of this study was to systematically evaluate this phase of the transplantation procedure in a follow-up study. 52 patients could be assessed in follow-up. Although the patients had already differed from the healthy control group in the areas of depression, quality of life, and physical complaints (p < 0.001) at the beginning of the study, there was a significant increase of depression and a further decline in the reported quality of life in the course of the study. The patients presented themselves as having a low internal and a significantly increased external and fatalistic locus of control. The study stresses the necessity for supportive psychotherapeutic therapy in these patients.
