Hyperemesis gravidarum as conversion disorder.

Psychosocial factors have long been believed to be important in the pathogenesis of emesis gravidarum (morning sickness) and hyperemesis gravidarum (HG). Although this has been confirmed during extensive studies over the last 30 years, HG has never been described as a conversion reaction. We describe two women presenting with hyperemesis who clearly fulfill diagnostic criteria for conversion. We suggest that strong psychodynamic conflicts are expressed by this potentially dangerous symptom in a subset of individuals and that dynamic interventions have a role in treating certain patients with HG.

Dividing "hysteria": a preliminary investigation of conversion disorder and psychalgia.

The longstanding diagnostic controversy over the concept of "hysteria" has taken on new significance with the advent and development of the third edition of the Diagnostic and Statistical Manual (DSM-III). The problem of defining hysteria is therefore discussed and re-examined. A retrospective study of cases diagnosed as conversion reaction or hysterical neurosis, conversion type was then completed and analyzed. These cases were redefined using DSM-III criteria and were analyzed using a number of demographic and clinical variables. In a comparison of those patients classified as having conversion and those classified as having psychalgia, no significant differences were found. Those patients under the diagnosis of conversion and those carrying the diagnosis psychalgia differed significantly from a control group of patients with random "neurotic" diagnosis on five variables: a) symptoms are defensive; b) symptoms are expressive; c) secondary gain; d) previous physical trauma; and e) previous conversion symptoms.

Abnormal somatosensory evoked potentials in two patients with conversion disorder.

On clinical grounds, somatosensory evoked potentials (SEP) and motor evoked potentials (MEP) are currently used to discriminate between hysterical and neurological conditions. The present paper reports on two patients with severe gait disturbance who had the near-total absence of SEP responses on the scalp during the symptomatic period, which normalized after recovery. These findings, along with others, may shed light on the brain correlates of conversion phenomena.

Conversion disorder after implant of a spinal cord stimulator in a patient with a complex regional pain syndrome.

IMPLICATIONS: This case history describes the treatment of a patient suffering with persistent pain. He was treated surgically with implantation of a spinal cord stimulator. After surgery, a partial paralysis that could not be explained medically and that was probably related to emotional factors occurred, and cognitive behavioral treatment was begun. This paper discusses the importance of considering social and psychological factors when medical treatment options are considered.

Pseudodystrophy. A conversion disorder mimicking reflex sympathetic dystrophy.

The authors suggest some criteria by which pseudodystrophy and reflex sympathetic dystrophy, although sharing some similar clinical features, can be distinguished as two different conditions, each requiring its own approach and management. The most important distinction is found on bone scintigraphy. In reflex sympathetic dystrophy the bone scan shows a typical increased tracer uptake (at least during stages I and II); in pseudodystrophy there is a normal or decreased tracer uptake in the affected region. Moreover the vascularization is increased in reflex sympathetic dystrophy stage I, whereas in pseudodystrophy hypovascularization is found from the beginning. The clinical features, as well as the results of technical investigations, psychological evaluation and treatment of 4 patients with pseudodystrophy are presented. The importance of distinguishing this condition from reflex sympathetic dystrophy is stressed.

Trauma-related dissociative (conversion) disorders in children and adolescents--an overview of assessment tools and treatment principles.

A high proportion of patients in child and adolescent psychiatry with significant dissociative symptomatology after early childhood traumatization may go undiagnosed, be wrongly diagnosed and/or inappropriately treated. The diagnostics and treatment of dissociative disorders have been limited by lack of comprehensive, reliable and valid instruments and the ongoing polarization and fierce controversy regarding treatment. However, recent neurobiological findings of neurochemical, functional and structural cerebral consequences of early stressful childhood experiences point out a need for active, early and effective identification and treatment interventions. We present an update on assessment tools available in the Nordic countries, and an overview of different appropriate therapeutic intervention models for children and adolescents. A systematic overview of studies of dissociation in children and adolescent published over the last decade disclosed a total of 1019 references. The 465 papers describing aspects of assessment tools and/or treatment were studied in detail. Reliable and valid screening questionnaires and diagnostic interviews for children and adolescents now allow for effective early identification of dissociative disorders. A combination of individual psychotherapy, pharmacotherapy and family therapy are often required to handle dissociative disorders in children and adolescents. Cognitive-behavioural therapy, hypnotherapy, Eye-Movement Desensitization-Reprocessing (EMDR), psychodynamic therapy and an integrated approach are the main described psychotherapeutic approaches, but treatment of dissociation in children and adolescent does not require allegiance to any one particular treatment model. However, achievement of physical safety by providing a safe environment is a primary goal that supersedes any other therapeutic work. Assessments tools are now available, and appropriate therapeutic intervention models may hopefully contribute to reduce the risk of wrong diagnoses and inappropriate treatment of dissociative symptomatology in children and adolescents. However, controlled clinical trials of the various interventions and longitudinal outcome studies are needed.

Salient findings: A potentially groundbreaking study on the neuroscience of hypnotizability, a critical review of hypnosis' efficacy, and the neurophysiology of conversion disorder.

Three papers of special interest to researchers and clinicians alike have recently appeared in the general scientific and medical literatures. Two of these papers are original research studies that employ brain-imaging technologies, one using Magnetic Resonance Imaging (MRI), the other position emission tomography (PET). A third paper is a comprehensive review of the empirical findings on the clinical use of hypnosis in pediatric oncology. The research study using MRI technology is extraordinary, because it is the first to document differences in brain morphology between high hypnotizable and low hypnotizable individuals. Arguably, if its findings replicate, the study could be one of the most important developments in scientific hypnosis since the genesis of the Stanford scales 45 years ago. The PET study notes differences in brain activation during intentionally simulated and hypnotically experienced paralysis. The review article examines empirical work addressing the efficacy of hypnosis for procedural pain in pediatric oncology.
