The SCL-90-R as a screening instrument for severe personality disturbance among outpatients with mood and anxiety disorders.

Our objective was to examine whether the SCL-90-R, a widely used self-report measure of distress and psychopathology, could screen for personality disorders in general and for severe personality disturbance (SPD) in particular, at the time when patients seek treatment for a state (mood or anxiety) disorder. The SCL-90-R was administered to 112 consecutive outpatients with various mood and anxiety disorders. The personality severity index (PSI) score, defined as the mean value of the scores on the SCL-90-R subscales of interpersonal sensitivity, hostility, and paranoid ideation, was compared with the current symptom index (CSI) score, defined as the mean value of the scores on the remaining six SCL-90-R subscales. A positive screen was considered if PSI > CSI. SPD was defined as the presence of any DSM-III-R Cluster A and/or Cluster B personality disorder. The accuracy of the screen was verified by means of the Structured Clinical Interview for DSM-III-R Personality Disorders. The sensitivity of the PSI > CSI criterion to screen for SPD was 89.4%, while its sensitivity to screen for any DSM-III-R personality disorder was 72.9%. The SCL-90-R subscales that contributed the most to the screening discriminability of this SCL-90-R-derived screening measure were hostility, paranoid ideation, somatization, and obsessive-compulsive behavior. The SCL-90-R may be used to screen for SPD in routine work with outpatients with mood and anxiety disorders, but the results of the screening need to be verified because of the possibility of false negatives and false positives, although that possibility is apparently low. These findings may have important prognostic and treatment implications.

Germinoma: unusual imaging and pathological characteristics. Report of two cases.

Primary germ cell neoplasms of the central nervous system typically develop as midline mass lesions during the first three decades of life. The authors present two cases with atypical clinicopathological features that stimulate discussion on the diagnosis and management of these tumors. The first patient was an 11-year-old boy of Japanese-American heritage who presented with a 6-month-long history of cognitive decline, difficulty swallowing, unsteady gait, and intermittent right-sided posturing. The initial magnetic resonance (MR) image of the brain displayed a mildly increased T2 signal in the cerebral peduncles, putamen, and globus pallidus bilaterally. Follow-up MR images showed an increase in the T2 signal abnormality in the left basal ganglia. The second patient was a 10-year-old Caucasian boy who presented with diabetes insipidus and subsequently displayed progressive fatigue, involuntary eye and mouth movements, and obsessive-compulsive behavior. An MR image demonstrated signs of mineral deposition and foci of increased T2 signal in both basal ganglia. Follow-up MR images demonstrated a progressive increase in the T2 signal (which was then located within the mesial temporal lobe). A biopsy performed on the left thalamic lesion in the first patient revealed a germinoma. The patient was treated with chemotherapy and died 2 years later. The second patient underwent a lumbar puncture, which demonstrated an elevated level of beta-human chorionic gonadotropin. Despite the lack of a mass on MR images in this child, the need for a tissue diagnosis prompted the authors to perform an anterior temporal lobectomy. The diagnosis of diffuse germinoma was confirmed, and the patient was treated with adjunctive chemotherapy. Although uncommon, germ cell tumors can present outside the midline and exhibit a multifocal growth pattern.

Pharmacologic therapies aid treatment for autism.

In the absence of other guidelines, practitioners often prescribe by analogy with roles of psychotropic medicines in other psychiatric disorders (e.g., the ability of serotonergic antidepressants to reduce compulsive behavior). There is a slow but steady accumulation of data supporting the use of psychotropic medications to manage certain symptoms in children with autism. These data support the use of stimulant medications for attention/hyperactivity symptoms, with willingness to suspend such treatment if a trial is unsuccessful. Risperidone is supported for other disruptive behaviors, especially of an irritable/disruptive nature, but with attention to increases in appetite and weight. SSRIs and atypical antipsychotics may be helpful for a variety of perseverative behaviors, although one would seldom prescribe antipsychotic medication for mild perseverative behavior alone. SSRIs may be useful for anxiety. Again, there is no compelling evidence that existing pharmacologic treatments have a major role in treating the core symptoms of autism, especially the profound impairments in social interaction and communication. Further well-designed double-blind studies with significant numbers of subjects and defined target symptoms will provide the data that will guide therapeutic decisions in the future.

Homeostatic and toxic mechanisms regulating manganese uptake, retention, and elimination.

This review attempts to summarize and clarify our basic knowledge as to the various factors that potentially influence the risks imposed from chronic exposure to high atmospheric levels of manganese (Mn). The studies describe the interrelationship of the different systems in the body that regulate Mn homeostasis by characterizing specific, biological components involved in its systemic and cellular uptake and its elimination from the body. A syndrome known as manganism occurs when individuals are exposed chronically to high levels of Mn, consisting of reduced response speed, intellectual deficits, mood changes, and compulsive behaviors in the initial stages of the disorder to more prominent and irreversible extrapyramidal dysfunction resembling Parkinson's disease upon protracted exposure. Mn intoxication is most often associated with occupations in which abnormally high atmospheric concentrations prevail, such as in welding and mining. There are three potentially important routes by which Mn in inspired air can gain access the body to: 1) direct uptake into the CNS via uptake into the olfactory or trigeminal presynaptic nerve endings located in the nasal mucosa and the subsequent retrograde axonal transport directly into the CNS; 2) transport across the pulmonary epithelial lining and its subsequent deposition into lymph or blood; and/or 3) mucocilliary elevator clearance from the lung and the subsequent ingestion of the metal in the gastrointestinal tract. Each of these processes and their overall contribution to the uptake of Mn in the body is discussed in this review as well as a description of the various mechanisms that have been proposed for the transport of Mn across the bloodbrain barrier which include both a transferrin-dependent and a transferrin-independent process that may involve store-operated Ca channels.

Familial dementia with Lewy bodies (DLB).

We report a rare familial case of dementia with Lewy bodies (DLB). The patient was a man who died at the age of 51. His parents were first cousins. Among three siblings, two were diagnosed as probable cases of DLB, and one was a possible case, according to the clinical diagnostic criteria of the consortium on DLB. Following the patient's autopsy, he was found to have had DLB without neurofibrillary tangles or senile plaques (pure form of diffuse Lewy body disease). His other siblings have been followed for more than ten years. Although these patients with familial DLB displayed clinical variability, all three siblings showed progressive dementia of early onset and progressive language disorder with paraphasia and difficulty in finding words. Psychotic features were also seen in the three siblings. The patient's sister showed compulsive behavior, and the other two siblings showed symptoms of parkinsonism. Neuropathologically, in addition to the usual neuropathology of DLB, the autopsy findings showed numerous small spheroids in the stratum pyramidale from the subiculum to CA1 of the hippocampus. Significant neuronal loss in CA2-3 of the hippocampus was detected. Axonal flow disturbance may be involved in the hippocampal formations of this incidence of familial DLB.

[Psychosomatic findings in patients with contact granuloma--initial results].

In a prospective study, 33 patients with vocal cord granulomas were seen in a psychosomatic interview and given questionnaires. Results showed the significance of psychosomatic factors in the occurrence of vocal cord granulomas. Psycho-social stress situations, particularly in private lives, and losses of emotionally significant persons were of prime importance. Two types of personalities--a narcissistic and a psychosomatic type--were represented about equally. In the personality structure of the patients, compulsive behavior was diagnosed most frequently while depressive features occurred to a lesser degree. Supportive and expressive psychotherapy was indicated in two thirds of the cases.

Psychological manifestations of vertigo: a pilot prospective observational study in a Portuguese population.

We sought to ascertain the importance of psychological manifestations of vertigo and psychogenic vertigo among a Portuguese population. Sixty patients complaining of vertigo and imbalance were studied over a 2-year period. At each assessment, the patients underwent a general examination, a neurootological evaluation, psychiatric interviews, and psychopathological assessments conducted by a multidisciplinary team. Overall, 38 patients (63.4%) were given diagnoses of some form of psychopathological complaint. A more detailed analysis revealed panic disorder in 9, moderate depressive episode in 42, and mixed anxiety and depressive disorder in 7, whereas the remaining patients (2) suffered from subclinical symptoms of anxiety or depression. Patients with vertigo demonstrate a high incidence of psychopathological complaints, the most common being anxiety disorders. Somatization, obsessive-compulsive behaviors, and depression tend to lessen over time, whereas few changes are seen in anxiety.

Anorexia nervosa as a compulsive behaviour disease.

A number of anorexic young women develop bulimia, a condition in which binge eating is driven so intensely they cannot resist it. Although this drive has the character of a compulsion the patients do not as a rule suffer from obsessional-compulsive neurosis. A questionnaire was developed and used to determine whether similar compulsive drives manifest themselves in restricting anorexics and whether there are compulsive features resembling patients with compulsive personality disorder (as described in DSM-III) in eating disorders. A total of 162 patients were studied, comprising 42 controls, 30 depressed patients, 34 non-bingeing anorexics, 28 bingeing anorexics and 28 compulsive patients. The questionnaire was shown to be a stable instrument and, on the compulsion scale, the anorexics, bulimics and compulsive patients all scored very highly (mean +/- S.E.; 32.1 +/- 1.9, 35.8 +/- 1.9, 28.0 +/- 2.2, respectively) compared to the controls (13.1 +/- 1.1, p < 0.005). The compulsive patients did not have anorexia-type eating disorders. It was concluded that many of the factors which underlie compulsive personality disorder are present in primary eating disorders and the compulsive nature of anorexia could not be ignored when treatment was considered. The difference between compulsive behaviour and addiction is discussed in the light of the failure of long-term naloxone infusion to cure severe anorexia, even though some patients had dramatic weight gains associated with the antilipolytic action of naloxone.

Regional cerebral glucose metabolic abnormality in Prader-Willi syndrome: A 18F-FDG PET study under sedation.

UNLABELLED: Prader-Willi syndrome (PWS) is a genetic disorder caused by the nonexpression of paternal genes in the PWS region of chromosome 15q11-13 and is the most common cause of human syndromic obesity. METHODS: We investigated regional brain metabolic impairment in children with PWS by 18F-FDG PET. Sixteen children with PWS (9 males, 7 females; mean age +/- SD, 4.2 +/- 1.1 y) and 7 healthy children (4 males, 3 females; mean age +/- SD, 4.0 +/- 1.7 y) underwent brain 18F-FDG PET in the resting state. The images of PWS children were compared using statistical parametric mapping analysis with those of healthy children in a voxelwise manner. RESULTS: Group comparison showed that children with PWS had decreased glucose metabolism in the right superior temporal gyrus and left cerebellar vermis, regions that are associated with taste perception/food reward and cognitive and emotional function, respectively. Metabolism was increased in the right orbitofrontal, bilateral middle frontal, right inferior frontal, left superior frontal, and bilateral anterior cingulate gyri, right temporal pole, and left uncus, regions that are involved in cognitive functions related to eating or obsessive-compulsive behavior. Interestingly, no significant metabolic abnormality was found in the hypothalamus, the brain region believed to be most involved in energy intake and expenditure. CONCLUSION: This study describes the neural substrate underlying the abnormal eating behavior and psychobehavioral problems of PWS.

[Differential diagnosis of hoarding behaviors].

Hoarding of objects comprises a continuum from normality to extreme disease. It is important to distinguish between the different disorders that include hoarding behaviors. Compulsive hoarding is a form of obsessive-compulsive disorder (OCD) that is characterized by excessive acquisition of possessions, inability to discard possessions, and excessive clutter. Patients usually display other obsessive features, feel distress if they cannot hoard objects, show a typical cognitive pattern with obsessive features, and their interpersonal relations are mediated by objects. Diogenes syndrome is the combination of severe self-neglect, domestic squalor, social withdrawal, hoarding, and refusal of help, in elderly patients. There is high comorbidity with psychiatric/somatic disorders. Depression and dementia are risk factors for self-neglect. Collectionism is a normal phenomenon that is common in children but also found in adults. It is usually an organized activity, and the objects are kept in specific and structured places. The aim of collecting is to organize and hierarchize a series of objects, not just to hoard them. Collected objects are frequently appreciated by other collectors, and become exchanged to enlarge the collection.

Healing the wounded, neglected inner child of the past.

Childhood experiences of the past can have a destructive effect on the present. The inner child in each person is the core of the personality that has been molded by the directions on how to act to be loved that the person receives in childhood. Painful experiences and lack of nurturing in dysfunctional families wound the inner child and contaminate adult experiences. Many persons with eating disorders have a wounded or neglected inner child that affects their adult lives. Characteristically, they demonstrate problems with trust, intimacy, addictive and compulsive behaviors, and codependence among others. Healing the inner child by grieving neglected childhood developmental needs is a long process, but one that improves the quality of one's life. Nurses, depending on their educational background and clinical skills, can help clients move toward understanding and healing the wounded, neglected inner child of the past.

[Psychogenic hemorrhages].

Psychogenic "purpura" consists in the spontaneous appearance of recurrent bruising, it is a reality which is still unexplained. Most often woman with an underlying emotional disorder are affected. In addition to cutaneous ecchymoses and hematomas they may have menometrorrhagia, hematuria, epistaxis and gastrointestinal bleeding in addition to many other complaints encompassing multiple organ systems. Cutaneous bruising is heralded by a burning or stinging sensation followed after a few hours by local warmth, puffiness and erythema, most often with some itching. The pain subsides when the ecchymoses appear a day later or earlier. Blood coagulation and hemostatic tests remain normal in all patients. A rare but poorly studied variety of psychogenic bleeding are religious or other stigmata with periodic bleeding at hands and feet, under the left breast and at the forehead, occasionally with bloody tears. It would be risky to substitute one poorly understood diagnosis (stigmata) with another (hysterical conversion). It is very difficult to distinguish spontaneous psychogenic from selfinflicted iatrogenic bleeding (purpura factitia) because patients may have the same obsessive-compulsive behavior or hysterical trait. Moreover, patients with self-induced bleeding act in a most clever manner and their continuous observation is difficult. The differential diagnosis with the "battered child" syndrome is rather easy. Other bleeding disorders with normal coagulation tests are an inherited failure of the collagen biosynthesis (f.i. Ehlers-Danlos syndrome) or congenital or acquired vascular disorders (purpura senilis of Bateman, vitamin C deficiency, morbus Schamberg, purpura annularis of Majocchi, orthostatic purpura). There is virtually no scientific information on the interaction between the nervous system and hemostasis or blood coagulation. The only therapeutic approach in patients with psychogenic bleeding is psychiatric with particular attention to the sociocultural background of the patient and his family.
