Structural factor analyses for medically unexplained somatic symptoms of somatization disorder in the Epidemiologic Catchment Area study.

BACKGROUND: Assess the latent structure of the DSM-III somatization symptoms and the stability of symptom patterns over time. METHODS: Cross-sectional and longitudinal covariation of symptoms of somatization disorder were investigated using structural equation models in a population-based data set from the Epidemiologic Catchment Area study. RESULTS: Medically unexplained physical complaints were discovered to cluster into three separate factors, consistent with the DSM-IV definition of somatization disorder, but one dominant general factor was defined, consistent with the DSM-III conceptualization. Individual symptom prevalences and factor structures were different for men and women. The factor structures remained stable at 1 year follow-up. Variations in the threshold of number of somatization symptoms required for diagnosis affected prevalence, sex ratio and temporal stability of the diagnosis. CONCLUSIONS: These population-based results support dimensional models of somatization. Implications for changing the threshold of the categorical diagnosis of somatization disorder and providing better care for these patients are given.

A clinical approach to the somatizing patient.

Patients with chronic, unexplained physical complaints are evaluated diagnostically in two steps in primary care: (1) brief consideration of three specific, but rare, disorders (somatic delusion, conversion, and malingering); and (2) extensive consideration of the remaining three common but overlapping disorders (somatization disorder, hypochondriasis, and psychogenic pain). Because of frequent confusion in differentiating among the common somatizing disorders and because the treatment is similar for all, the family physician can be content with the general designation of "common somatization syndrome" when unable to distinguish among them. This diagnosis can be easily established by a good history and physical examination. Psychiatric referral is required for the rare somatizing disorders. The primary physician can manage the majority of the common somatizing patients by observing the following principles: develop a good physician-patient relationship, apply techniques of behavior modification, engage the patient at the somatic level but extend it to include associated life stresses, strategically use symptomatic measures, treat depression with full doses of antidepressants, and accept the importance of ongoing contact with the patient irrespective of symptoms. When these therapeutic principles are employed, decreased morbidity, medical utilization, and cost can be expected to follow.

[Somatoform disorders. Historical development and modern diagnostic conceptualization].

Patients with "medically unexplained" bodily symptoms form a major group in the medical care system. Diagnostic and therapeutic problems very often arise, and the concept of "somatization" promotes a better understanding of this patient group. Important historical stages in the development toward a modern diagnostic classification of somatoform disorders are outlined. A critical comment on the diagnostic approaches according to DSM-IV and ICD-10 follows.

[Mechanisms of psychological defense in patients treated by long-term hemodialysis].

Using the ++clinico-psychopathological method and experimental psychological techniques the mechanisms of psychological defence were studied in 46 patients with chronic renal failure. The adaptation character of the mechanisms of psychological defence was shown in terms of the dynamics of their types depending on the stage and treatment of the disease. The role of the sex, premorbid personality type of the patient, the type of the disease course, nature of mental traumas in the formation of psychological defence is validated. The relationship between the development of mental disorders and the mechanisms of psychological defence is analyzed.

The functional somatic symptom.

The functional somatic symptom is a disorder that is prevalent in diverse patient populations. It is a heterogeneous disorder composed of a number of separate but often overlapping psychiatric disorders. The consultation-liaison psychiatrist is often consulted by his or her physician colleagues for help in the diagnosis and treatment of this difficult group of patients. This requires an understanding of the different dynamic formulations available to explain these disorders and a treatment strategy that emphasizes a collaborative approach to the long-term management of these patients.

Brainstem conundrum: the Chiari I malformation.

PURPOSE: To describe the Chairi I Malformation in relation to the anatomy of the brain and spinal cord, the common manifestations of the condition, diagnostic considerations, and management for the primary care provider. DATA SOURCES: Extensive review of the world-wide scientific literature on the condition, supplemented with actual case studies. CONCLUSIONS: The adult Chairi I Malformation is an insidious congenital brainstem anomaly that consists of caudal displacement of the cerebellar tonsils, brainstem and fourth ventricle into the upper cervical space, resulting in overcrowding of the posterior fossa. IMPLICATIONS FOR PRACTICE: Due to the vague, and often ambiguous presenting symptoms of Chiari I Malformation, many patients are misdiagnosed with conditions such as multiple sclerosis, fibromyalgia, chronic fatigue syndrome, or psychiatric disorders. Patients frequently experience symptoms months to years prior to accurate diagnosis and often incur irreversible neurologic deficits.

Illness as a lifestyle. The role of somatization in medical practice.

Persons with psychological problems who translate their distress into somatic symptoms (somatize) are frequent users of medical care. These patients often have underlying depression, anxiety, obsessive--compulsive symptoms, or personality disorders. Descriptions of the somatizing syndromes are provided in association with recommendations as how to recognize and manage the patient with somatization.

A review of the somatoform and factitial disorders for the podiatrist.

In this article, the author discusses psychiatric disorders that present as physical illness with no underlying organic cause. The most common types are presented with their clinical presentation, causation, and treatment. It is intended that the practitioner will be able to include these disorders in the different diagnoses of the patients who have symptoms that are difficult to diagnose and are not responsive to therapy.

Hysterical symptoms masking brain stem glioma.

To function effectively as primary care specialists, psychiatrists must remain ever alert to the possibility of organic disorders in patients who at first show only psychiatric symptoms. A case is presented in which hysterical overlay led to misdiagnosis in a 31 year woman, who dies of a diffuse medullary glioma 3 1/2 years after onset of "conversion" symptoms. The authors point out how the label "hysterical" clouds longitudinal objective diagnostic observations especially when initial clinical and laboratory data fail to support a definitive organic diagnosis.

Computational issues in mapping variation affecting susceptibility to complex disorders: the chicken and the egg.

Linkage mapping strategies for complex disorders have evolved under a variety of constraints. Some of these constraints reflect the nature of complex disorders and are manifest in limitations on the kinds of data that can be collected, while others were (at least historically) strictly computational. This paper focuses on how computational issues have impacted the design of studies on complex disorders and, conversely, how our study designs have influenced the computational issues that have been addressed. We now have unprecedented computational resources, but also face unprecedented computational and methodological challenges as we move from the linkage mapping of genes influencing susceptibility to complex disorders toward the identification of the actual variation affecting susceptibility to these disorders. The near-term computational and methodological issues we must address will be profoundly influenced by the study designs of the recent past. But future study designs, as well as our investments in computational and methodological research, ought to be developed considering the computational and informatics resources we now have at hand.

The differential diagnosis of epilepsy, pseudoseizures, dissociative identity disorder, and dissociative disorder not otherwise specified.

The authors review the co-occurrences of dissociative symptoms and disorders with epilepsy and pseudo-seizures and examine newer diagnostic instruments that assist in accurate diagnosis of persons with concomitant seizure behaviors and dissociative symptoms. They also review seizure behaviors and electroencephalographic findings in persons with dissociative identity disorder (DID) and dissociative disorder not otherwise specified (DDNOS) and dissociative symptoms in persons with epilepsy and with pseudoseizures. Dissociative symptoms in 15 patients with epilepsy and 15 with pseudo-seizures were examined using the Dissociative Experiences Scale (DES) and the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D). On the SCID-D, pseudo-seizure patients had significantly higher dissociative symptom scores than epileptic patients, but DES scores did not reliably distinguish epileptic and pseudo-seizure patients. Misdiagnosis of persons with seizures and dissociative symptoms can be avoided by careful adherence to DSM dissociative disorder criteria, the use of video-EEG monitoring, and systematic assessment of dissociative symptoms with the SCID-D.

High incidence of esophageal motor disorders in consecutive patients with globus sensation.

Thirty consecutive patients with globus sensation who were referred to a psychosomatic clinic prospectively underwent otolaryngological, videokinematographic, and manometric examinations of pharynx and esophagus to evaluate whether morphological abnormalities or motility disorders underlay their symptom. When indicated by findings, 24-hour pH-metry, scintigraphy of bolus transport, and esophagogastroscopy were performed. Seven patients were shown to have achalasia, 10 had "hypochalasia" (lower esophageal sphincter relaxation less than 75% with esophageal contraction abnormalities but no complete distal aperistalsis), and 1 had diffuse esophageal spasms; 2 patients had also hyperplastic lingual tonsils, 1 had tonsillitis, and 1 had a cervical spondylophyte. Nutcracker esophagus and nonspecific contraction abnormalities were found in 7 patients, and gastroesophageal reflux with esophagitis and a low lower esophageal sphincter resting pressure was found in 1; only 3 patients had normal esophageal motility. None had volunteered dysphagic symptoms at primary evaluation. Psychometric investigations in consenting patients showed no higher mean scores for state and trait anxiety, depression, hysteria, and hypochondriasis than in general medical outpatients. Esophageal motor disorders may, before giving rise to dysphagia, be sensed more vaguely and induce the globus sensation. However, only disappearance of the sensation after treatment allows inferring an etiological significance of such a disorder.

Whose hysteria: Briquet's, Janet's or Freud's?

Somatisation disorder (Briquet's syndrome) is a recent addition to psychiatric nosology. It represents an attempt to describe a syndrome of 'hysteria', the term initially applied to this polysymptomatic disorder by Guze and his colleagues. The manner of identification of this syndrome, however, has been the subject of criticism. This brief review suggests that the ideas of Janet, who worked at Salpetriere 30 to 40 years after Briquet, may provide a more precise approach to diagnosis. Furthermore, his hypotheses about predisposition to this disorder are seen to offer a preliminary way towards its understanding. Recent experimental evidence lends some support to Janet's hypotheses.

Conversation skills training of thought-disordered schizophrenic patients through attention focusing.

An attention-focusing procedure was designed as discrete trials and multiple prompts with contingent social reinforcement to facilitate the acquisition of conversational skills in thought-disordered schizophrenia patients. Three patients with DSM-III-R diagnoses of schizophrenia completed a standard social skills training program and the attention-focusing procedure in multiple baseline experimental designs. While social skills training had little effect on the acquisition of skills, patients who completed the attention-focusing procedure significantly increased performance of conversational skills and showed some generalization of trained behaviors.

The treatment of nonepileptic seizures: historical perspectives and future directions.

Nonepileptic seizures (NES) are neuropsychiatric disorders presenting with a combination of neurologic signs and underlying psychological conflicts. For more than a century, the medical community has accumulated data and insights about the phenomenology, epidemiology, risks, comorbidities, and prognosis of NES. However, we have not progressed much beyond anecdotal reports of treatments for NES, and no randomized, controlled trials of treatment for the disorder have been conducted. We review the diagnosis and treatment of NES and suggest directions for future research in these areas.

Camptocormia.

Camptocormia is a disabling psychiatric condition characterized by a fixed flexion of the spine usually occurring during the stress or anticipation of battle. We present an illustrative case study and a summary of six cases. In this clinical sample the camptocormia was associated with a high likelihood of a history of significant back trauma; this lends to difficulty in assigning a diagnosis from the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R). Camptocormic patients retained in the military have a poor prognosis; rapid diagnosis and medical separation is recommended.
