Relation of anxiety and other psychometric measures, balance deficits, impaired quality of life, and perceived state of health to dizziness handicap inventory scores for patients with dizziness.

BACKGROUND: An important question influencing therapy for dizziness is whether the strengths of the relationships of emotional and functional aspects of dizziness to 1) anxiety and other mental states, 2) perceived state of health (SoH) and quality of life (QoL) are different in patients with and without normal balance control. We attempted to answer this question by examining these dimensions' regression strengths with Dizziness Handicap Inventory (DHI) scores. METHODS: We divided 40 patients receiving group cognitive behavioural therapy (CBT) and vestibular rehabilitation for dizziness, into 2 groups: dizziness only (DO) and normal balance control; dizziness and a quantified balance deficit (QBD). Group-wise, we first performed stepwise multivariate regression analysis relating total DHI scores with Brief Symptom Inventory (BSI) sub-scores obtained pre- and post-therapy. Then, regression analysis was expanded to include SoH, QoL, and balance scores. Finally, we performed regressions with DHI sub-scores. RESULTS: In both groups, the BSI phobic anxiety state score was selected first in the multivariate regression analysis. In the DO group, obsessiveness/compulsiveness was also selected. The correlation coefficient, R, was 0.74 and 0.55 for the DO and QBD groups, respectively. When QoL and SoH scores were included, R values increased to 0.86 and 0.74, explaining in total 74, and 55% of the DHI variance for DO and QBD groups, respectively. Correlations with balance scores were not significant (R ≤ 0.21). The psychometric scores selected showed the strongest correlations with emotional DHI sub-scores, and perceived QoL and SoH scores with functional DHI sub-scores. CONCLUSIONS: Our findings suggest that reducing phobic anxiety and obsessiveness/compulsiveness during CBT may improve emotional aspects of dizziness and targeting perceived SoH and QoL may improve functional aspects of dizziness for those with and without normal balance control.

Effects of a program of cognitive-behavioural group therapy, vestibular rehabilitation, and psychoeducational explanations on patients with dizziness and no quantified balance deficit, compared to patients with dizziness and a quantified balance deficit.

BACKGROUND: We examined whether a program combining cognitive-behavioural therapy (CBT), vestibular rehabilitation (VR) and psychoeducation is equally effective in improving psychometric measures in patients with dizziness independent of a balance deficit. Measures of patients with dizziness only (DO) were compared to those of patients also having a quantified balance deficit (QBD). METHODS: 32 patients (23 female, 9 male) with persistent dizziness were analysed as 2 groups based on stance and gait balance control: those with QBD (pathological balance) or DO (normal balance). Dizziness Handicap Inventory (DHI) and Brief Symptom Inventory (BSI) questionnaires were used pre- and post-therapy to assess psychometric measures. Patients then received the same combination therapy in a group setting. RESULTS: The QBD group mean age was 60.6, SD 8.3, and DO group mean age 44.8, SD 12.1, years. Pre-therapy, questionnaire scores were pathological but not different between groups. Balance improved significantly for the QBD group (p=0.003) but not for the DO group. DHI and BSI scores improved significantly in the DO group (0.001

Mental body transformation deficits in patients with chronic balance disorders.

BACKGROUND: Movements may be generated consistent with imagining one's own body transformed or "disembodied" to a new position. Based on this concept we hypothesized that patients with objective balance deficits (obj-BD) would have altered neural transformation processes executing own body transformation (OBT) with functional consequences on balance control. Also we examined whether feeling unstable due to dizziness only (DO), without an obj-BD, also lead to an impaired OBT. METHODS: 32 patients with chronic dizziness were tested: 16 patients with obj-BD as determined by balance control during a sequence of stance and gait tasks, 16 patients with dizziness only (DO). Patients and 9 healthy controls (HCs) were asked to replicate roll trunk movements of an instructor in a life size video: first, with spontaneously copied (SPO) or "embodied" egocentric movements (lean when the instructor leans); second, with "disembodied" or "transformed" movements (OBT) with exact replication - lean left when the instructor leans left. Onset latency of trunk roll, rise time to peak roll angle (interval), roll velocity, and amplitude were measured. RESULTS: SPO movements were always mirror-imaged. OBT task latencies were significantly longer and intervals shorter than for SPO tasks (p < 0.03) for all groups. Obj-BD but not DO patients had more errors for the OBT task and, compared to HCs, had longer onset latencies (p < 0.05) and smaller velocities (p < 0.003) and amplitudes (p < 0.001) in both the SPO and OBT tasks. Measures of DO patients were not significantly different from those of HCs. CONCLUSIONS: Mental transformation (OBT) and SPO copying abilities are impaired in subjects with obj-BD and dizziness, but not with dizziness only. We conclude that processing the neuropsychological representation of the human body (body schema) slows when balance control is deficient.

Health care provider communication training in rural Tanzania empowers HIV-infected patients on antiretroviral therapy to discuss adherence problems.

OBJECTIVES: Self-reported adherence assessment in HIV-infected patients on antiretroviral therapy (ART) is challenging and may overestimate adherence. The aim of this study was to improve the ability of health care providers to elicit patients' reports of nonadherence using a "patient-centred" approach in a rural sub-Saharan African setting. METHODS: A prospective interventional cohort study of HIV-infected patients on ART for ≥ 6 months attending an HIV clinic in rural Tanzania was carried out. The intervention consisted of a 2-day workshop for health care providers on patient-centred communication and the provision of an adherence assessment checklist for use in the consultations. Patients' self-reports of nonadherence (≥ 1 missed ART dose/4 weeks), subtherapeutic plasma ART concentrations (< 2.5th percentile of published population-based pharmacokinetic models), and virological and immunological failure according to the World Health Organization definition were assessed before and after (1-3 and 6-9 months after) the intervention. RESULTS: Before the intervention, only 3.3% of 299 patients included in the study reported nonadherence. Subtherapeutic plasma ART drug concentrations and virological and immunological failure were recorded in 6.5%, 7.7% and 14.5% of the patients, respectively. Two months after the intervention, health care providers detected significantly more patients reporting nonadherence compared with baseline (10.7 vs. 3.3%, respectively; P < 0.001), decreasing to 5.7% after 6-9 months. A time trend towards higher drug concentrations was observed for efavirenz but not for other drugs. The virological failure rate remained unchanged whereas the immunological failure rate decreased from 14.4 to 8.7% at the last visit (P = 0.002). CONCLUSIONS: Patient-centred communication can successfully be implemented with a simple intervention in rural Africa. It increases the likelihood of HIV-infected patients reporting problems with adherence to ART; however, sustainability remains a challenge.

[Physician-patient communication in medical education: can it be learned?]. / Zur Erlernbarkeit der Arzt-Patienten-Kommunikation in der Medizinischen Ausbildung.

Based on a review of recent key articles, this paper demonstrates that many elements of physician-patient communication can be learned successfully during medical education. Methods of assessment and definition of success depend largely on the definition of teaching goals, which are usually based on the principles of a more egalitarian and non-paternalistic physician-patient communication. In this article another approach is suggested. Teaching objectives in patient-physician communication can also be deduced from the needs of clinical medicine, resulting in the following goals: students are able to gather relevant data from patients' history, they explicitly structure the consultation and the way they give information, they know how to respond to patients' emotions. The Objective Standardised Clinical Examination (OSCE) is discussed with its strengths and weaknesses. The inclusion of video-based feedback is presented as a teaching tool to improve students' self-reflection. Workplace-based assessment and Mini-CEX are promising educational tools that require a well-trained faculty, not only in the teaching and practice of communication but also in the art of giving constructive and yet honest feedback.

Beyond content analysis and non-verbal behaviour - what about atmosphere? A phenomenological approach.

OBJECTIVE: Basic research and careful observation of clinical practice have yielded a vast amount of empirical data on communication in health care. This research has been guided by the assumption that good communication will be better understood and easier to teach when its single constituents are identified. This paper points to the limitation of this approach. METHODS: Based upon the terminology of phenomenological thinking grounded in neo-phenomenology (Hermann Schmitz) contradictory findings from the literature on patient-centred communication in Internal Medicine and Oncology are used as a starting point to elucidate different paradigms in conducting research in clinical communication. RESULTS: The phenomenological approach of the German philosopher Hermann Schmitz (*1928) is briefly presented. It is based upon experiences that 'on the average everybody can vividly access or retrieve from his memory'. Empirical research does not provide unequivocal advice how to communicate with an individual patient. Likewise, researchers note unexpected reactions from real patients-they do not behave as the expert would assume. The inclusion of the phenomenon of a certain atmosphere is proposed referring to the impression of 'something in the air' that sometimes can be identified during communication or upon entering a room. Even though it can be sensed with high evidence, it cannot be deduced from particular observations. Instead, the atmosphere is part of a situation in which meaning is dissolved in chaotic manifoldness. Sensing an atmosphere is a function of the lived body (Leib) as opposed to phenomena that are mediated by the senses. CONCLUSION: Current research and teaching models cover only part of the phenomenology of professional communication. How research and education might profit from the addition of Schmitz' philosophical approach will be outlined in this article. PRACTICE IMPLICATIONS: Including perceptions of the lived body (Leib) should improve research in clinical communication and teaching courses.

Communication during ward rounds in internal medicine. An analysis of patient-nurse-physician interactions using RIAS.

OBJECTIVE: Describe the content and of mode of patient-physician-nurse interactions during ward-rounds in Internal Medicine. METHODS: In 267/448 patients, 13 nurses, and 8 physicians from two wards in General Internal Medicine 448 interactions on ward rounds were tape recorded by observers. After exclusion of interactions with more than three participants (N=150), a random sample of 90 interactions was drawn. Data were analysed with a modified RIAS version that allowed for the registration of a third contributor and for the assessment of the direction of a communicative action (e.g.: nurse-->patient, etc.). Furthermore, time spent per individual patient was registered with a stop-watch. RESULTS: A total of 12,078 utterances (144 per ward round) were recorded. Due to problems with the comprehensibility of some interactions the final data set contains 71 ward round interactions with 10,713 utterances (151 per ward round interaction). The average time allotted to an individual patient during ward-rounds was 7.5 min (range: 3-16 min). The exchange of medical information is the main topic in physicians (39%) and nurses (25%), second common topic in patients (28%), in whom communicative actions like agreement or checking are more common (30% patients/25% physicians/22% nurses). Physicians and patients use a substantial number of communicative actions (1397/5531 physicians; 1119/3733 patients). Patients receive about 20 bits of medical or therapeutic information per contact during ward-rounds. CONCLUSIONS: If ward rounds serve as the central marketplace of information nurses' knowledge is under-represented. Further research should try to determine whether the quality of patient care is related to a well balanced exchange of information, to which nurses, physicians, and patients contribute their specific knowledge. PRACTICE IMPLICATIONS: Given the fact that in-patients in Interna Medicine usually present complex problems, the exchange of factual information, expectations, and concepts is of paramount importance. We hope that this paper is going to direct the attention of the scientific community to the characteristics of ward-rounds because they will remain the central marketplace of communication in hospital.

[Psychotherapy in a patient with lupus erythematodes--a disease with an uncertain course]. / Zum therapeutischen Umgang mit Patienten, die an einer chronischen Krankheit mit unklarem Verlauf leiden--das Beispiel eines Patienten mit Lupus erythematodes.

The autoimmune disease Systemic LE (SLE) poses major adjustment problems because the course of the illness is unpredictable. Informing patients thus, does not provide clarity but include information about the fallibility of medical information or prognosis. Even though effective manual based psychological treatment programs exist, an individualised approach seems to be more appropriate. However, reports on individual psychotherapeutic interventions have not been reported sufficiently. The paper describes the short-term treatment of a patient with SLE. In his case cognitive deficits could be attributed to a CNS participation of SLE; central was an identity problem related to the disease. Within a few hours a substantial improvement of his condition could be achieved.

Validation of TONOPORT V blood-pressure measuring monitor in adults.

A new automatic blood-pressure (BP) measuring device TONOPORT V was evaluated according to the International Protocol for Validation of Blood Pressure Measuring Devices in adults by the European Society of Hypertension. BP values measured by the TONOPORT V were compared to BP readings from two independent observers. A total of 33 patients (20 males, 13 females) provided systolic and diastolic BP readings in the normotensive, borderline hypertensive, and hypertensive range. Their age varied between 30 and 83 years, and their arm circumference between 23 and 36 cm. The device showed a mean (+/-s.d.) deviation from observer measurements of -0.7 (4.6) mmHg for systolic and -0.8 (4.4) mmHg for diastolic BP. The accuracy of the device did not vary according to BP values or other patient characteristics. The device passed all phases of the protocol and can be recommended following the regulation rules of the European Society of Hypertension.

A quantitative analysis of anaesthetist-patient communication during the pre-operative visit.

Previous communication research in general medical practice has shown that effective communication enhances patient compliance, satisfaction and medical outcome. It is expected that communication is equally important in anaesthesia, since patients often suffer from anxiety and lack of knowledge about anaesthetic procedures. However, little is known about the nature of communication during routine anaesthetic visits. The present study of 57 authentic anaesthetic visits provides the first results on the structure and content of communication in the pre-operative setting using the Roter Interaction Analysis System (RIAS). Patient-centred communication behaviours of anaesthetists and the extent of patient involvement were particularly investigated. From the 57 pre-operative visits, 18 267 utterances were coded. The mean (SD) [range] duration of the visit was 16.1 (7.8) [3.7-42.7] min. Anaesthetists provided 169 (68) and patients 153 (82) utterances per visit (53.5% vs. 46.5%). Physician and patient gender had no impact on the distribution of utterances and the duration of the visit. Conversation mainly focussed on biomedical issues with little psychosocial discussion (< 0.1% of all anaesthetist utterances). However, anaesthetists quite frequently used emotional comments toward patients (7%) and involved them in the conversation. The use of facilitators, open questions and emotional statements by the anaesthetist correlated with high patient involvement. The amount of patient participation in anaesthetic decisions was assessed with the Observing Patient Involvement Scale (OPTION). Compared with general practitioners, anaesthetists offered more opportunities to discuss treatment options (mean (SD) OPTION score 26.8 (16.8) vs. 16.8 (7.7)).

Cardiovascular indices of peripheral and central sympathetic activation.

OBJECTIVE: A number of sympathetic nervous system (SNS) parameters have been used in cardiovascular psychophysiology. This study aimed to describe the pattern and redundancy of a set of SNS parameters during peripherally induced changes of cardiac sympathetic activation and reflex modulation of central SNS control. Preejection period (PEP) was assessed as a marker of peripheral sympathetic activation. Low-frequency blood pressure variability (BPV) was assessed as an estimate of central SNS control. METHODS: Peripheral beta-sympathetic stimulation and blockade were achieved with epinephrine and esmolol hydrochloride (beta1-blockade), respectively. Changes in central SNS output were induced by loading and unloading arterial baroreceptors with norepinephrine and nitroprusside sodium, respectively. This single-blinded, crossover study in 24 healthy men also included two placebo control periods. PEP was derived from impedance cardiography and adjusted individually for heart rate. BPV was calculated by power spectral analyses of beat-to-beat heart rate and systolic blood pressure (Finapres system) data. RESULTS: PEP decreased during epinephrine infusion (-40.1 +/- 3.8 ms, p <.0001) and increased during esmolol infusion (+6.6 +/- 3.5 ms, p =.05). PEP was shortened after central SNS activation by nitroprusside (-16.8 +/- 2.9 ms, p < 0.0001). Systolic BPV in the low-frequency range (0.07-0.14 Hz, Mayer waves) increased during nitroprusside infusion (+0.44 +/- 0.19 ln mm Hg(2), p =.03) and decreased during norepinephrine infusion (-0.67 +/- 0.13 ln mm Hg(2), p < 0.0001). Low-frequency BPV did not change significantly during epinephrine or esmolol infusion. CONCLUSIONS: Our data provide empirical evidence of separable peripheral and central sympathetic response components. The combined report of low-frequency BPV and PEP gives distinct information on both central SNS control and the level of sympathetic cardiac activation achieved.

Pharmacokinetics and pharmacodynamics of clomethiazole after oral and rectal administration in healthy subjects.

Clomethiazole, a sedative-hypnotic and anticonvulsant drug, has been successfully administered orally and intravenously, but in cases where either of these methods presents complications, rectal administration may represent a practical alternative. We sought to compare the single-dose pharmacokinetics and pharmacodynamics of clomethiazole after oral and rectal administration. Ten healthy adult volunteers were given 600 mg clomethiazole edisylate (corresponding to 390 mg clomethiazole base) in 2 capsules as a single oral or rectal dose in a double-masked, double-dummy, crossover fashion. Serum concentrations were measured up to 10 hours after administration using a specific high-performance liquid chromatography method. Computerized reaction-time measurement and visual analogue scales (VAS) were used to assess drug effects. Peak serum concentrations were significantly higher after oral administration (mean +/- SEM, oral 1.76 +/- 0.47 microg/mL vs rectal 0.48 +/- 0.14 microg/mL; P = 0.03) and appeared earlier (55 +/- 12 vs 89 +/- 11 min; P = 0.04). Area under the concentration-time curve values were similar after administration by both routes (oral 116 +/- 20.6 vs rectal 105 +/- 36.0 microg x min/mL), with a relative rectal bioavailability of 90% compared with oral administration. The objective pharmacodynamic effects on reaction time (increase of 104 +/- 26 vs 66 +/- 22 ms, oral vs rectal) and working speed (decrease of 132 +/- 38 vs 97 +/- 32 ms, oral vs rectal) were not significantly different. Subjective pharmacodynamic effects, as measured on the VAS, were comparable with both routes of administration. Clomethiazole was well tolerated, with a similar adverse effect profile for both routes of administration. The effects of rectal dosing of clomethiazole were similar to those of oral dosing but appeared to occur later. Our results suggest that rectal administration of a single 600-mg clomethiazole edisylate dose bears no safety risk. Therefore, rectal administration could be considered when neither oral nor parenteral administration is possible and a later onset of effect is not critical.

Midazolam effects on prepulse inhibition of the acoustic blink reflex.

AIMS: The eye-blink response following sudden acoustic noise bursts is part of the startle reflex. The magnitude of the startle response can be attenuated by presentation of a weak stimulus before the 'startle-eliciting' stimulus (prepulse inhibition, PPI). PPI is a stable finding in awake humans but may be altered by anaesthetic drugs. We investigated whether the application of benzodiazepines altered the magnitude of PPI in healthy male volunteers. METHODS: In an open-label noncontrolled investigation, the effect of the benzodiazepine agonist midazolam on PPI was assessed in the absence and presence of the antagonist flumazenil. After an initial control period of 60 min three consecutive periods, each of 60 min, with progressively increasing concentrations of midazolam were studied (0. 02, 0.06, 0.14 mg kg-1 h-1 ). A final 60 min period during the administration of flumazenil (0.004 mg kg-1 h-1 ) and while the agonist was still present was also studied. Drug was administered intravenuously as a combination of bolus, 50% of total dose and continuous infusion over the 60 min period. Electromyographic (EMG) response of the right orbicularis oculi muscle was used to assess the startle response to noise bursts of 50 ms duration (95 dB(A)). Noise bursts were randomly preceded by nonstartling prepulses (800 Hz sinus, 50 ms duration, 65 dB(A), prepulse to noise interval 120 ms). The magnitude of PPI was calculated by dividing the EMG response to nonprepulsed stimuli by the response to prepulsed stimuli for each individual and period. Eleven subjects participated in the study, two of them were excluded from the statistical analysis because startle responses could not be reliably elicited (final sample size n=9). RESULTS: The magnitude of PPI was inversely related to the concentration of midazolam. This relationship was described by a sigmoidal Emax model, giving an Emax of 0.65+/-0.13, an ED50 of 33.9+/-10.9 ng ml-1 and gamma of 3.5+/-1.0. During infusion of flumazenil and in the presence of midazolam, the magnitude of PPI increased by 0.11 (95% CI, 0-0.22, P

[Is self-management practical in bronchial asthma?]. / Sind Selbstkontrolle und Selbstbehandlung beim Asthma bronchiale sinnvoll?

The threat and uncertainty involved in an asthma attack reduce the quality of life for the patient. Life quality can be improved if the patient learns self-management principles. This is easy to learn and involves a simple procedure requiring the patient to refer to written instructions in the event of an asthma exacerbation. As a basis for treatment the patient needs to measure maximum peak flow, which can be done with an easy-to-use peak flow meter. A value above 80% of the personal best indicates that the treatment has been successful. By means of printed instructions in credit card format, the appropriate treatment for particular peak flow values and/or symptoms can be looked up and administered. So far there have been no self-management studies providing a definite answer on what interventions are effective and cost-effective. One clear result is that inhaled steroid therapy must be initiated early. Learning self-management patently leads to improvement in the patient's life quality and safety. In the long run this concept appears to be cost-saving with regard to days lost through sickness and hospitalization.

Effect of beta blockade with and without sympathomimetic activity (ISA) on sympathovagal balance and baroreflex sensitivity.

Beta blockers increase heart rate variability (HRV) and improve survival in coronary artery disease (CAD). The benefit of beta blockers with intrinsic sympathomimetic activity (ISA) in CAD still remains a matter of debate, and their effect on HRV has not yet been investigated. Therefore, we measured HRV, systolic blood pressure variability (BPV) and baroreflex sensitivity (BRS) under propranolol (PROP, without ISA, 160 mg q.d.), pindolol (PIN, with potent ISA, 15 mg q.d.) and placebo (PLA, q.d.) in 30 healthy subjects, aged 21-39 years, during controlled frequency breathing (0.30 Hz) in supine and tilt positions. PROP increased HRV in the high-frequency (0.15-0.40 Hz) band (PROP 7.4 +/- 1.0; PLA 6.9 +/- 1.4; PIN 6.8 +/- 1.0 ln MI2; P = 0.003), decreased BPV in the low-frequency band (at 0.1 Hz, Mayer waves) (PROP 0.6 +/- 0.7; PLA 1.3 +/- 1.1; PIN 1.2 +/- 1.2 ln mmHg2; P = 0.001) and enhanced BRS (PROP 14.6 +/- 9.5; PLA 8.0 +/- 6.8; PIN 8.7 +/- 6.8 ms mmHg-1; P = 0.001) in the supine position. After passive tilt, PROP decreased HRV in the low-frequency band (PROP 6.1 +/- 0.9; PLA 6.5 +/- 1.1; PIN 6.9 +/- 0.7 ln MI2; P < 0.001) and decreased Mayer waves (PROP 1.8 +/- 0.8; PLA 2.4 +/- 1.0; PIN 2.7 +/- 0.8 ln mm Hg2; P < 0.001). PIN increased the low-frequency HRV response, which is induced by passive tilt (PIN + 0.9 +/- 1.0; PLA + 0.3 +/- 1.3, PROP + 0.3 +/- 1.0 ln MI2; P = 0.026). Our results prove that beta-adrenergic blockade with potent ISA does not increase HRV, has no beneficial effect on autonomic balance and even exaggerates sympathetic responses to passive tilt.

Improving communication skills--a randomized controlled behaviorally oriented intervention study for residents in internal medicine.

OBJECTIVE: We investigated whether patient-centered communication skills can be taught to residents in Internal Medicine by using a time-limited behaviorally oriented intervention. METHOD: Residents working at the Department of Internal Medicine were randomly assigned to an intervention group (IG; N = 19) or a control group (CG; N = 23). In addition to 6 hours of standard medical education per week, the IG received specific communication training of 22.5 hours duration within a 6-month period. Initially and 10 months later, participants performed interviews with simulated patients. Interviews were rated by blinded raters who used the Maastricht History and Advice Checklist-Revised. RESULTS: Compared with the CG, the IG improved substantially in many specific communication skills. Both groups improved in the "amount of medical information identified" and in the ability to "communicate about feasibility of treatment." CONCLUSION: Patient-centered communication skills such as those presented in this intervention study can be taught. The ability to gain medical information and the readiness to communicate about aspects of medical treatment seem to improve with more professional experience; however, they also profit from the intervention.

[From perception to symptom--from symptom to diagnosis. Somatoform disorders as a communication phenomenon between physician and patient]. / Von der Wahrnehmung zum Symptom--vom Symptom zur Diagnose. Somatoforme Störungen als Kommunikationsphänomen zwischen Arzt und Patient.

Patients with somatoform disorders probably constitute the largest diagnostic group in daily medical practice. A major communication problem forms the core of somatoform disorders: patients report about complaints which their physicians do not understand; there is no sufficient biological reason for the patient's symptoms. This article discusses the multifactorial origin of somatoform disorders, consisting of minimal physiological changes, the perception of bodily sensations, and their interpretation as symptoms (non-normal perceptions), as well as ensuing emotional and behavioral consequences. Concerning the communication problem, it is important to realize that patients normally present symptoms, whereas the underlying bodily perceptions and the explanatory models are rarely communicated to the physician. On the physician's side, symptoms presented by patients are subjected to his or her explanatory concepts translating symptoms into indicators of certain diseases. Thus, the information introduced into physician-patient communication by the patient has usually passed several cognitive circuits within the patient or between the patients and other significant conversation partners thus shaping its specific components. It is recommended that physicians try to trace back their patients' symptoms to bodily sensations and explanatory models in order to base their diagnostic and therapeutic reasoning on the same kind of information. Empirical evidence is presented to support the inter-dependence of the components of the model, on both the patient's and the physician's side. Therapeutic interventions based upon the model are presented.

Psychological and metabolic improvement after an outpatient teaching program for functional intensified insulin therapy (FIT).

To be the master of their disease and not its slave is the ultimate goal of many patients with diabetes. Intensified functional insulin therapy (FIT) helps to establish this goal by an intensive patient education: each patient learns in five small-group sessions how s/he reacts to standardized challenges of glucose homeostasis (e.g. 24 h fasting; physical exercise; various carbohydrate loads). We investigated in 43 patients with long-standing diabetes type 1 (mean age: 33 +/- 10 years; mean duration of diabetes: 15 +/- 10 years) whether FIT improves quality of life, influences metabolic control and doctor-patient relationship. The following instruments were used: diabetes specific quality of life questionnaire (DQOL), hierarchical distance and cohesion between doctor and patient (FAST), anxiety and depression (HAD). Pre and post intervention values were compared with paired t-tests. HbA1c and number of hypoglycaemic episodes were also assessed 1 year after FIT and 1 year prior to FIT. Metabolic control was improved: HbA1c in the year before FIT: 6.72 +/- 1.35; 4 months before FIT: 6.61 +/- 1.46; 4 months after FIT: 6.29 +/- 1.09 (P < 0.05 compared to 4 months before FIT); 1 year after FIT: 6.46 +/- 1.12 (n.s. compared to 1 year before FIT). Dissatisfaction with life decreases from 33.3 +/- 8.0 to 28.5 +/- 7.7 (P < 0.001). Moments free of disease-specific strain increase from 74.3 +/- 13.9 to 78.1 +/- 16.1 (P = 0.07). Hierarchical distance between doctor and patient decreases from 1.1 +/- to 0.6 +/- 0.8 (P < 0.001), cohesion increases from 9.3 +/- 1.5 to 9.9 +/- 1.1 (P < 0.001). Anxiety and depression both decreases significantly: anxiety, 6.5 +/- 3.3-->4.6 +/- 3.2 (P < 0.001); depression, 2.7 +/- 2.5-->1.5 +/- 1.6 (P < 0.001). The number of patients with severe hypoglycaemic episodes (level 4) decreases from five (11.6%) to one (2.3%) after intervention (P < 0.05). In conclusion, FIT enhances quality of life in diabetic individuals. It helps to establish a less hierarchical and closer relationship between patient and doctor as revealed by the FAST data. It should be emphasized that the psychological improvements are not achieved at the expense of less strict metabolic control.

[Somatoform disorders and their therapy]. / Somatoforme Störungen und ihre Therapie.

Somatoform disorders are frequent manifestations of psychosocial stress and present themselves in form of unexplained somatic symptoms. Diagnostics and treatment of somatoform disorders is mainly performed in order to uncover organic pathology. However, organic pathology could not be found, which leads to repeated investigations finally contributing to increase of health costs. Authors highlight pathogenesis of somatoform disorders, summarise the syndromes of this group of disorders and give recommendations as to management and treatment.
