Prevention of the complications of diabetes.

Until drugs that will prevent metabolic derangements that cause the complications of diabetes have been developed, the best approach to their prevention is control: of hyperglycemia, of hypertension, of obesity, and of smoking. Intensive insulin therapy, although demonstrably effective, must be approached with caution because hypoglycemia is a potentially life-endangering threat. Conversely, a Danish study has demonstrated a decrease in hypoglycemic episodes with intensive insulin therapy (Parving HH. Personal communication, 1988). With this in mind, it may be essential to bring blood glucose levels into a reasonable range shortly after the diagnosis of diabetes mellitus has been made. Insulin therapy is required for type I diabetic patients, and it may also be an appropriate therapy for all type II patients who do not become rapidly normoglycemic following diet and oral sulfonylurea treatment. Some physicians believe that a frontal "attack" of a split-mixed program of insulin therapy when type II diabetes is diagnosed is of psychologic as well as physiologic benefit, impressing the patient with the importance of control and vigilance. Compliance to rigid dietary change is notoriously unsuccessful, and the "trial-and-failure" approach, often ending in insulin therapy in any case, may not be the most effective. The advent of easy-to-use blood glucose monitoring devices and convenient and discreet insulin delivery systems has made maintenance of glycemic control less difficult for the insulin-using patient. New antihypertensive agents, lipid-reducing drugs, and second-generation sulfonylureas that do not affect the quality of life are now available and should be used in the person with diabetes as necessary.(ABSTRACT TRUNCATED AT 250 WORDS)

Balint, the doctor, and the fear of being unscientific.

The current debate on the contribution of Michael Balint's work to general practice has been initiated by Sowerby's (1977) lengthy critique.Sowerby's arguments, however, depend on one particular definition of science, simplify some complex issues, and have rigid and restrictive qualities. I give some examples to illustrate this.Secondly, Sowerby's definition of the science of psychology leads to an intellectual separatism which Balint sought to reduce. The alternative diagnosis of ;depressive illness' is neither more helpful nor precise.Finally, criticisms of Balint seminars which Sowerby perceives as dangerous are challenged. I argue that Balint's approach in verifying and refuting hypotheses in the face of prospective observations and evidence was truly scientific.

Effect of electromyographic feedback and static stretching on artificially induced muscle soreness.

Thirty-six male subjects aged 18 to 26 years were assigned at random to one of three treatment groups: biofeedback, static stretch, and control. Muscle soreness was produced in all subjects by an 80% maximal eccentric contraction of the biceps brachii. The subjects in the biofeedback group applied auditory electromyographic (EMG) feedback at 6, 25, 30, 49, and 54 hours after the exercise, and the stretch group applied static stretch to the exercised arm at the same time periods. Observations of EMG activity and perceived pain level were made immediately before and after exercise, and at 24, 48, and 72 hours following exercise. When compared with a control group, both auditory biofeedback and static stretching significantly reduced EMG muscle activity but had no significant effect on perceived pain. The EMG activity and perceived pain of the subjects in each treatment group significantly differed across observations.

A preliminary investigation of self-reported personality disorders in late life: prevalence, predictors of depressive severity, and clinical correlates.

Previous research suggests that personality disorders, particularly in clusters A and C, persist into late life, are particularly prevalent in late-life depressed samples, and negatively impact treatment of late-life depression. The present study examined the self-reported personality disorder traits of a sample of 65 depressed elders using the Wisconsin Personality Disorder Inventory IV (WISPI IV). As expected, clusters A and C were most prevalent and the presence of a personality disorder predicted the maintenance or re-emergence of depressive symptoms, as did hopelessness and ambivalence regarding emotional expression. No specific personality disorder traits were associated with clinical features of late-life depression (age of onset, number of previous episodes) while some personality disorder traits were associated with psychological correlates of depression (hopelessness, ambivalence regarding emotional expression, thought suppression). A theoretical explanation for the cluster prevalence based on self-verification is discussed along with a profile of elderly patients who may have poor depression treatment course if they exhibit personality disorder traits, particularly interpersonal rigidity or avoidance, chronic hopelessness, and emotional inhibition.

Parkinson's syndrome, depression and imipramine. A preliminary report.

Patients with Parkinson's syndrome whose major symptoms are akinesis, rigidity, inertia, depression, irritability and failure of adaptation rather than tremor appear to benefit in a global way from therapy with imipramine. Patients without much over-all functional impairment do not show this improvement. The hypothesis is offered that motivation to move and ability to move are perhaps neurologically as well as psychologically related functions.

Traumatic stress in the 21st century.

OBJECTIVE: The introduction to a series of articles on traumatic stress aims to examine the ambivalent relationship between traumatic stress and psychiatry. It provides an outline to the very significant contribution that this field made before the conceptualisation of posttraumatic stress disorder (PTSD) and how the research and theoretical thinking in this field can provide many insights into the relationship between environmental factors and psychological health. It focuses on the relevance of this field to general psychiatry. RESULT: Posttraumatic stress disorder has emerged as the most common anxiety disorder in women. As well, there are high rates discovered in a range of chronically ill psychiatric patient populations. In particular, strategies for dealing with the issues of childhood abuse and neglect are not often considered by adult psychiatric services for the chronically and severely mentally ill, despite there being important predictors of suicidal behaviour, hospitalisation and prolonged disability. An effective consideration of the available evidence is often complicated by concerns about the impact of financial compensation on the presentation of psychopathology. This is a complex social dialectic whose impact is important to the practise of psychiatry. Equally, this field in itself must avoid becoming excessively rigid in its clinical definitions and the particular interventions which are espoused. CONCLUSIONS: The impact of traumatic events on long-term psychological adjustment and physical health have been under estimated. Identification of those at risk is an important issue given that effective treatments are now available. This is an area in which further conceptual thinking is required. It also provides particular opportunities to explore the biological processes of, and interaction between, the environment and the underlying genetic and neurobiological processes which are critical to the modulation of psychopathology.

Lengthening shortened penis caused by Peyronie's disease using circular venous grafting and daily stretching with a vacuum erection device.

PURPOSE: We evaluated the results of chronic intermittent stretching with a vacuum erection device after circumferential tunical incision and circular venous grafting in 4 patients with penile shortening from severe Peyronie's disease. MATERIALS AND METHODS: We performed complete circumferential tunical incision and covered the defect with a circular venous graft in 4 patients with shortened penis as a result of Peyronie's disease. Preoperative evaluation included determination of patient and partner expectations, potency status, measurement of penile length after intracavernous injection and color duplex ultrasonography to determine possible vascular communication. Lower saphenous, upper saphenous and deep dorsal veins served as graft materials. We advised patients to use a vacuum device on a daily basis for 6 months starting 1 month after surgery. Postoperative evaluations were done at 6 and 18 months postoperatively. RESULTS: At 6-month followup 1 patient who did not use the vacuum device gained 1 inch in penile length and was not available for further followup. The other 3 patients each gained 2 inches but had decreased erectile rigidity due to narrowing in the grafted area (hourglass deformity). One patient who wanted a more natural erection elected penile prosthesis implantation about 1 year after grafting. The remaining 2 patients gained 3 inches at 18-month followup and regained partial penile rigidity similar to preoperative erections when the hourglass deformity improved. All patients were satisfied and indicated that surgery improved psychological well-being as well as relationships with partners. CONCLUSIONS: The results in this small group are satisfactory. Our technique offers a reasonable solution for correction of penile shortening in patients with Peyronie's disease.

[Agoraphobia and "psychogenic"-attributed gait disorder as symptoms of "stiff-man" syndrome].

We report on two patients with truncal rigidity and agoraphobia. The fear of crossing open places had been judged as psychogenic in both cases. The detection of positive GAD-antibodies led to our final diagnosis. Treatment with liquorphoresis and clonazepam or diazepam alone resulted in a prompt amelioration of the rigidity and, to a lesser extent, of the agoraphobia as well. The stiff-man syndrome has neurological and psychological aspects and shows one more facet of the syndrome of agoraphobia first described by Westphal.

Stress, cancer and immunity. New developments in biopsychosocial and psychoneuroimmunologic research.

Research in biobehavioral oncology has been focused on stress as one dispositional factor in the multifactorial origin and in the clinical progression of malignant disease. New insights into the transduction of environmental influences to the immune system and to other body systems by the brain and neurotransmitters have increased the salience of this approach. Behavioral medicine in the area of cardiovascular disease has been successful due to the introduction of a "Type A" or coronary prone behavior pattern in large epidemiologic studies. This pattern is marked by both psychologic and physiologic hyperresponsiveness. Type A persons appear to be hostile, easily angered, competitive and hard-driving. More recently, behavioral oncologists have similarly attempted at conceptualizing a "Type C" or biopsychosocial cancer risk pattern, as they have noted the denial and suppression of emotions, in particular anger. Other features of this pattern are "pathological niceness", avoidance of conflicts, exaggerated social desirability, harmonizing behavior, over-compliance, over-patience, as well as high rationality and a rigid control of emotional expression ("anti-emotionality"). This pattern, usually concealed behind a facade of pleasantness, appears to be effective as long as environmental and psychological homeostasis is maintained, but collapses in the course of time under the impact of accumulated strains and stressors, especially those evoking feelings of depression and reactions of helplessness and hopelessness. As a prominent feature of this particular coping style, excessive denial, avoidance, suppression and repression of emotions and own basic needs appears to weaken the organism's natural resistance to carcinogenic influences. This may mean that the excessive use of denial and suppression/repression has important psychophysiologic effects linked to tumor biology and host-defense. Recent studies reveal that psychosocial stressors which are met by inadequate and repressive coping styles are associated with changes in immunocompetence, including both humoral and cell-mediated immunity. Relationships between different immune parameters (natural killer cell activity, lymphocytes, serotonin uptake, mean platelet volume) and mood states, psychological coping styles and personality variables are outlined. Recent findings indicate also that in certain malignancies (eg. breast cancer) the clinical course of the disease is influenced by psychosocial factors and coping style, as well as that the risk of cancer recurrence and metastasis is influenced by the type and duration of a given stressor. Individuals with a more favorable outcome have higher fighting spirit, a greater potential for aggression and lesser suppressive tendencies. Psychological intervention in cancer patients in its different forms and within the frame of the over-all treatment has now become a matter of scientific discussion and research.(ABSTRACT TRUNCATED AT 400 WORDS)

The "insolvable problem" as a determinant in the dynamics of suicidal behavior in children.

This paper attempts to define the characteristics of the "insolvable problem" in the dynamics of suicidal children. It posits that part of the underlying dynamics of suicidal children is being pressured to solve a problem, in the family milieu, which is beyond the child's--and often anybody else's--ability to resolve. Moreover, the paper outlines the possible relation between the insolvable problem and various determinants involved in suicidal behavior such as depression, helplessness, hopelessness, rigidity, etc. This discussion will be accompanied by case demonstrations.

Transmission of group II heteronymous pathways is enhanced in rigid lower limb of de novo patients with Parkinson's disease.

A potent heteronymous excitation of quadriceps motoneurones via common peroneal group II afferents has recently been demonstrated in normal subjects. The aim of this study was to investigate whether this group II excitation contributes to rigidity in Parkinson's disease. The early and late facilitations of the quadriceps H reflex elicited by a conditioning volley to the common peroneal nerve (CPN) at twice motor threshold, attributed to non-monosynaptic group I and group II excitations, respectively, were investigated. The comparison was drawn between results obtained in 20 "de novo" patients with Parkinson's disease (hemiparkinsonian, 17; bilateral, three) and 20 age-matched normal subjects. There was no statistically significant effect of "group" (patients/controls), "duration", "global severity" [Unified Parkinson's Disease Rating Scale (UPDRS)] or "side" (unilaterally versus bilaterally affected) factors on either group I or group II facilitations. To further the analysis, the factors of status (affected or non-affected limb), akinesia (lower limb akinesia score) and rigidity (lower limb rigidity score) were entered in a general linear model to explain the variations of the quadriceps H reflex facilitation. Rigidity was the only factor useful in predicting the value of the group II facilitation of the quadriceps H reflex (P < 0.007). Group I and group II facilitation was then compared between the rigid, non-rigid and control lower limbs [multivariate analysis of variance (MANOVA)]. Results are represented as mean +/- SEM (standard error of the mean). Group II facilitation was enhanced in the rigid lower limb of unilaterally affected patients (153.2 +/- 7% of control H reflex) compared with non-rigid lower limbs (124 +/- 4% of control H reflex; P < 0.007) or control lower limbs (126.1 +/- 4.1%; P < 0.01). There was no difference between the non-rigid lower limbs of the unilaterally affected patients and the control lower limbs, but a difference was observed between the rigid lower limbs of unilaterally less affected and bilaterally more affected patients (153.2 +/- 7% and 123.8 +/- 7.5% of control H reflex, respectively; P < 0.04). These results suggest a facilitation of the transmission in the interneuronal pathway activated by group II afferents in rigid lower limb of de novo hemiparkinsonian patients, probably resulting from a change in their descending monoaminergic inhibitory control.

Validation of the inflammatory bowel disease questionnaire in Swedish patients with ulcerative colitis.

BACKGROUND: The Inflammatory Bowel Disease Questionnaire (IBDQ) is a disease-specific health-related quality of life (HRQOL) questionnaire including four dimensions and a sum score. The aim of this study was to assess the internal and external validity, reliability, and sensitivity of a Swedish version of the IBDQ. METHODS: Three hundred consecutive patients with ulcerative colitis completed the IBDQ and three other health-related quality of life questionnaires (the Rating Form of IBD Patient Concerns (RFIPC), the Short Form-36 (SF-36) and the Psychological General Well-Being (PGWB) index). Disease activity was evaluated using a 1-week symptom diary, blood tests and rigid sigmoidoscopy. One hundred and fourteen patients filled in the questionnaire a second time, of whom 75 had been in stable remission for over 6 months and 39 had a significant clinical change in disease activity. RESULTS: Factor analysis of the 32 IBDQ items did not support the four dimensional scores. The dimensional scores had sufficient convergent validity, but low discriminative validity and homogeneity. The homogeneity was also low for the sum score. The inter-dimensional correlations were high. The concurrent validity was supported by correlations between the dimensional scores and other measures of disease activity and HRQOL. Patients in relapse scored significantly less on the sum score and the four dimensions compared to patients in remission. The test-retest correlations for the dimensional scores were 0.40-0.76. Patients with a change in disease activity during the 6-month follow-up period had a significant change in IBDQ scores not found in those who remained in remission. CONCLUSIONS: The Swedish version of the IBDQ had external validity and was shown to be a reliable and sensitive measure of HRQOL in ulcerative colitis, though there are some concerns regarding the internal validity. The use of a sum score was not supported and the questionnaire may benefit from a redivision of items into dimensions with better homogeneity and discriminative validity.

The effects of treatment on masticatory muscle activity and mandibular posture in myofascial pain-dysfunction patients.

The purpose of this study was to evaluate tonic masticatory muscle activity and the postural rest position of the mandible, pre- and post-treatment, in patients with TM disorders. Forty-one patients diagnosed as suffering from myofascial pain-dysfunction (MPD) were evaluated, with electromyography (EMG) used to measure the muscle activity of the masseteric and anterior temporal areas at rest. Postural rest position was assessed by measurement of interocclusal distance. Twenty-three asymptomatic subjects were also tested as controls. Treatment for the pain group emphasized cognitive awareness of dysfunctional orofacial behavior and biofeedback training of the masseteric area to teach masticatory muscle relaxation. The pre-treatment EMG values of both the masseteric and anterior temporal areas were significantly higher for the pain group than for the control group. Post-hoc division of the pain group into successful and unsuccessful subgroups was made on the basis of the degree of symptom improvement. EMG activity decreased significantly in the masseters of both subgroups, but only the unsuccessful subgroup showed a significant decrease in anterior temporal activity following therapy. Interocclusal distance was significantly increased in both subgroups. These results suggest that tonic masticatory muscle activity may be elevated in MPD patients. They also suggest that a decrease in EMG activity in the masseter and anterior temporalis muscles and an opening of the postural rest position of the mandible may accompany completion of psychophysiological therapy, but these changes do not correspond directly with the outcome of that therapy.

Perceptual causality in children.

Three experiments considered the development of perceptual causality in children from 3 to 9 years of age (N = 176 in total). Adults tend to see cause and effect even in schematic, two-dimensional motion events: Thus, if square A moves toward B, which moves upon contact, they report that A launches B--physical causality. If B moves before contact, adults report that B tries to escape from A--social or psychological causality. A brief pause between movements eliminates such impressions. Even infants in the first year of life are sensitive to causal structure in both contact and no-contact events, but previous research with talking-age children found poor verbal reports. The present experiments used a picture-based forced-choice task to reduce linguistic demands. Observers saw eight different animations involving squares A and B. Events varied in whether or not these agents made contact; whether or not there was a delay at the closest point; and whether they moved rigidly or with a rhythmic, nonrigid "caterpillar" motion. Participants of all ages assigned events with contact to the physical domain and events without contact to the psychological domain. In addition, participants of all ages chose causality more often for events without delay than with delay, but these events became more distinct over the preschool range. The manipulation of agent motion had only minor and inconsistent effects across studies, even though children of all ages considered only the nonrigid motion to be animal-like. These results agree with the view that perceptual causality is available early in development.
