Schizophrenic thought disorders: comparison between units of symptoms and axial syndrome

The schizophrenic axial syndrome postulates the presence of thought disorder and/or cryptic neologisms. The theory of symptom units postulates three groups of symptoms within the schizophrenic pattern. Each group arises through a special basic disturbance within the performance of experience close to the biological substrate. 465 schizophrenics have been examined personally at least twice within 8 years. We investigated signs (A) of subjectively perturbed experience of thoughts, such as transitoriness, disconnection, pressing, movielike thinking, double-sense thinking: withdrawal, broadcasting, telepathy, insertion, audible thinking, postresonance, echo; lack of impressivenes, veiled thinking, hazy thinking, thoughts getting stuck; thoughts getting muddled and crossed, condensation, contamination; (B) of perturbed performance of thinking, such as loosening of association, thought gaps, derailment, substitution, blocking, desultory thinking, tangentiality, performed word contaminations, word approximation, dissolution of terms, private use of words, disturbed formulation of the meaning of facts, vague thinking, paraphrasia, neologism, driveling. The series of general frequency shows: driveling 67.9%, desultory thinking 57.3%, withdrawal, broadcasting, insertion 32.7%, loosening of association, gaps, derailment 28.9%, blocking 16.5%, transitoriness, movielike thinking, double-sense thinking 12.0%. From the practical point of view, the time of the first manifestation of the symptoms is important. This will de demonstrated. The study confirms the presence of thought disorders in each case but at different times within the course depending on the type of course (phases, attacks, attack processes, process). With regard to these results the theory of symptom units can assist the practicability of the schizophrenic axis syndrome.

The diencephalon of the pacific herring,Clupea harengus: Cytoarchitectonic analysis

The cytoarchitecture of nuclei in the preoptic area, ventral thalamus, dorsal thalamus, epithalamus, hypothalamus, posterior tuberculum, synencephalon, and pretectum and the accessory optic nuclei was analyzed in the clupeomorph teleost, Clupea harengus. Plesiomorphic (evolutionarily primitive) and apomorphic (evolutionarily derived) features of nuclei were identified by cladistic analysis. Plesiomorphic features include the cytoarchitectonic organization of most of the preoptic nuclei, the somewhat scattered cells of nucleus ventrolateralis, the compact, oval shape of nucleus intermedius, the presence of dorsoventrally oriented laminae in the central posterior nucleus, and most features of the hypothalamic nuclei. Also plesiomorphic are the presence of a thick, prominent paraventricular organ, a nucleus of the paraventricular organ, a nucleus tuberis posterior, and a preglomerular complex in which the boundaries between multiple nuclei are relatively difficult to distinguish. Additionally, the cytoarchitecture of the three synencephalic nuclei present in Clupea, the presence of small cells in nucleus pretectalis superficialis pars parvicellularis and of larger, scattered cells in nucleus pretectalis superficialis pars magnocellularis, the presence of large cells in the dorsal accessory optic nucleus that form a rostrocaudally oriented column, and the feature of a small, cell-sparse ventral accessory optic nucleus are plesiomorphic. Apomorphic features include the presence of a single, large, circular lamina that surrounds a central neuropil in all but the most caudal part of nucleus anterior, a lack of bilateral asymmetry in the habenular nuclei, the relatively small size of the periventricular nucleus of the posterior tuberculum, the presence of two, distinguishable caudomedial nuclei in the posterior tuberculum, elongation and folding of the neuropil of nucleus pretectalis superficialis pars parvicellularis, and the relatively large size of nucleus pretectalis superficialis pars magnocellularis and the posterior pretectal nucleus. © 1993 Wiley-Liss, Inc.

Organizational structure and effectiveness in general hospital psychiatry departments

The relationship between organizational structure and effectiveness was examined in 33 psychiatry departments in general hospitals in Texas. Data were collected on 23 measures of organizational structure and 2 indices of effectiveness. The effectiveness measures were predesigned by the researchers and submitted to a nationwide panel of mental health experts to determine their practicality. The results of the study indicated that role specialization, centralization, standardization, and mode of conflict resolution were the most important predictors of effectiveness. Implications for administration of mental health services are discussed.Maxine L.

An autopsy case with peculiar acidophilic bodies in the dentate nucleus and brain stem, associated with degeneration of the pyramidal-extrapyramidal systems

Case S.S. 59 years of age, male. At the age of 25, he had admitted to sanatorium for 7 years because of pulmonary tuberculosis. After his discharge, at the age of 45, he had started complaining of depressive mood or the idea of suicide and admitted to a mental hospital. Psychiatric diagnosis was depression and slight mental retardation. Shortly after, his depressive mood was improved, but his hypochondriac attitude was unchanged. No tendency toward dementia was proven. At the age of 54, he became enable to walk. Neurologically, pyramidal and some sort of extrapyramidal signs, dysarthria, disturbance of swallowing, fecal and urinary incontinence became apparent. Laboratory data showed scarcely any abnormality. At the age of 59, he died of bronchopneumonia. Neuropathologically, moderate degeneration of dentate nucleus, slight degeneration of pyramidal tract from medulla oblongata to spinal cord, striatum, substantia nigra were found. Neither senile plaques nor neurofibrillary changes could be seen throughout central nervous system. The most important finding is the presence of peculiar acidophilic bodies. They are round or oval, 10 approximately 20 mu in diameter and distributed in dentate nucleus, oculomotor nucleus, central grey of midbrain, superior colliculus, putamen, pallidum, subthalamic nucleus, Zona incerta, hypothalamus, Locus coeruleus, reticular formation of midbrain and pons, pontine nucleus, raphe nucleus, vestibular nucleus, inferior olive in order of number of the bodies. These bodies are scattered in so-called ground substance, and have no relations to any cell bodies or cell processes.(ABSTRACT TRUNCATED AT 250 WORDS)     

Rehabilitation challenges in multiple sclerosis

While current immunomodulating drugs aim to reduce multiple sclerosis (MS) exacerbations and slow disease progression, rehabilitation aims to improve and maintain the functional abilities of patients in the face of disease progression. An increasing number of journal articles are describing the value of the many rehabilitation interventions that can be used throughout the course of the disease, from the initial symptoms to the advanced stages. An integrated team of healthcare professionals is necessary to address a myriad of problems to reduce impairments, disabilities, and handicaps. The problems may be related to fatigue, weakness, spasticity, mobility, balance, pain, cognition, mood, relationships, bowel, bladder, sexual function, swallowing, speech, transportation, employment, recreation, and activities of daily living (ADL) such as dressing, eating, bathing, and household chores. The team can help prevent complications and secondary disabilities, while increasing patient safety. Improving neurologically related function, maintaining good relationships, and feeling productive and creative adds enormously to the quality of life of people with MS and their families. Rehabilitation is more than an ‘extra’ service that is given after medical therapies; it is an integral part of the management of the diverse set of problems encountered throughout the course of the disease. An interdisciplinary team may have many members, including physicians, nurses, physical therapists, occupational therapists, speech and language pathologists, psychotherapists, social workers, recreational therapists, vocational rehabilitation therapists, patients, families, and other caregivers.     

Changes in body temperature after administration of adrenergic and serotonergic agents and related drugs including antidepressants

This survey, the third in a series, presents extensive tabulations of literature, primarily since 1965, on thermoregulatory effects of adrenergic and serotonergic agonists and their antagonists including ergot alkaloids, amphetamines, tryptamines, monoamine oxidase inhibitors, tricyclic and other antidepressants, a variety of other agents which alter presynaptic aminergic mechanisms including reserpine, 6-hydroxydopamine, p-chlorophenylalanine, alpha-methyltyrosines, cocaine, guanethidine and bretylium. The information listed includes the species used, route of administration and dose of drug, the environmental temperature at which the experiments were performed, the number of tests, the direction and magnitude of body temperature change and remarks on the presence of special conditions, such as age or lesions, or on the influence of other drugs, such as antagonists, on the response to the primary drug.

Plaidoyer pour la mise en place d’une stratégie globale pour atténuer le « fardeau » des troubles schizophréniques

This article attempts to identify and put into perspective the different approaches that could globally prevent the suffering induced by schizophrenia, from the detection of early psychosis to the impact on individual and family functioning and emotional health. Schizophrenia causes, at the community level, a number of difficult consequences and associated costs, which likely could be reduced if specific strategies, already known and documented internationally, were applied. Two areas not explored in this article: the role of medication and the issue of suicide prevention. In the scope of screening and early treatment, genetic risk, as well as the predictive ability of the clinical criteria for individuals at “ultra-high risk” of developing schizophrenia justify an increased vigilance for the detection of symptoms in order for treatment to begin earlier and to be more effective. These risk factors should not be neglected as the benefits of early management impact the course of illness and functional outcome. At this stage of the emergence of the disorder, it is difficult to systematize a therapeutic protocol. Two options are open to the clinician: “wait and watch” given the lack of a conclusive diagnosis and a more pro-active intervention, focused on the therapeutic alliance and enhancing insight and awareness. The second approach seems more productive but requires transparency with the patient and family regarding the uncertainty of the clinical situation, and an attitude that favors sharing information, along the lines of early psych education. Once a pathological stage is reached, early and accurate clinical care is fundamental. They depend heavily on access to care, proximity and availability to clinics or out-reach teams, capable of a thorough diagnostic work-up. Yet conversely, the availability for early and accurate clinical care faces obstacles which are closely related to the pejorative view of psychiatry held by the general public, health care professionals, and public officials. This poor image of psychiatry is partly due to cases of clinical decompensation, dangerous in some instances, underscoring why it is be important to understand and anticipate the contributory factors to these outcomes in the first place so as to avoid them. In this sense, defending a complacent and conciliatory approach can be counter-productive. Following developments of recent decades in other chronic diseases (diabetes, cancer, AIDS, severe heart disease…), the implementation of systematic clinical programs, treatment protocols, psycho-education to reinforce adherence to therapeutic measures, their simplification, the support and appreciation of the role of caregivers, destigmatizing due to proximity of contact, and therefore an increase in the use of care. Similarly, the systematic search for side-effects of medication and pro-actively managing to minimize their occurrence strengthen compliance, a recognized factor of relapse prevention. Preventable comorbidities, addictions, and common physical illnesses are not systematically screened (neoplastic diseases, diabetes, hypertension, dental health, gynecology…) in this population and thus also represent significant potential for a better life expectancy. The tools of psychosocial rehabilitation, unfortunately, are too infrequently used in France. Their goal is to improve the functional outcome of patients, a determinant of social integration and to lessen the burden shouldered by family and other carers, and ultimately to reduce exacerbations of the illness due to situations of interpersonal stress. Work has also proven its worth as a protective factor, as well as strengthening a sense of self-efficiency, of self-esteem, of empowerment, of quality of life, helping attain recovery. It is clear that not all social and health care systems are primarily geared towards these objectives, although they have at their disposal, by the means described above, strong preventive measures for relapses. Beyond the issue of the implementation of clinical programs, the existing culture would benefit from being infused with a prioritization of resource deployment, with debates of these issues regarding parity for mental health services, advocated by users, and forging a place, for example, for the intervention of “peer supports”, sociologists, social workers, interested beyond the disease, in community environment, employment opportunities, and housing. Overall, this work argues for updating our conceptions of clinical care, supporting the systematic implementation of modern models of care, and expanding the scope of our concerns regarding patients’ lives.     

Assessment of roentgenographic lucencies of the skull: a systematic approach.

A review of roentgenologic characteristics of cranial vault defects suggests these criteria as favoring benign etiology: solitariness and small size, parasagittal location, smooth edges, sclerosis of margin, peripheral vascularity, and presence of bone remnants within the lesion. The more of these criteria that are present, the greater is the likelihood of benignity. Conversely, the presence of multiple defects of large size or scores of defects of small size, ragged undermined edges, total bone penetration, lack of peripheral vascularity, of absence of marginal sclerosis is presuptive evidence of malignancy.     

Autoradiographic localization of calcitonin gene-related peptide binding sites in human and rat brains

125I-calcitonin gene-related peptide (CGRP) binding sites were mapped in the human brain and rat brains by in vitro macroautoradiography, and compared to each other. Binding experiments were made to characterize 125I-CGRP binding on the human and rat brains. Scatchard analysis of saturation experiments from slide-mounted sections of the human and rat cerebellum displayed 125I-CGRP binding sites with a dissociation constant (Kd) of 0.17 nM and 0.11 nM, respectively, and a maximal number of binding sites (Bmax) of 96.8 fmol/mg and 23.0 fmol/mg protein. 125I-CGRP binding was time-dependent, reversible and saturable with high affinity in the brains. Autoradiograms showed a discrete distribution of 125I-CGRP binding sites throughout the brains of human and rat with patterns similar to each other. In the human brain, the highest binding was seen in the cerebellum, inferior olivary nuclear complex, certain parts of the central gray matter, arcuate nuclei of the medulla oblongata and dorsal motor nucleus of the vagus, and densities of CGRP-binding sites were high in the nucleus accumbens, amygdala, tail of the nucleus caudatus, substantia nigra, ventral tegmental area, medial portion of the inferior colliculus, medial pontine nuclei, locus coeruleus, inferior vestibular nucleus, substantia gelatinosa of the spinal trigeminal nucleus, nucleus of the solitary tract and nucleus cuneatus lateralis. In the rat, high densities were found in the hippocampus pars anterior, nucleus accumbens, ventral and caudal portions of the nucleus caudatus-putamen, central and basolateral nuclei of the amygdala, caudal portion of the insular cortex, medial geniculate body, superior and inferior colliculi, certain portions of the central gray matter, locus coeruleus, inferior olivary nuclei, vagal complex, nucleus cuneatus lateralis and cerebellum. In contrast, in both species, most of the cortical areas including the hippocampus, most of the thalamus, and hypothalamus exhibited few binding sites. In addition, high quantities of the binding sites were seen on the pia mater and on walls of blood vessels in the brain and subarachnoidea. These results revealed essentially homologous locations of CGRP binding sites in the human and rat central nervous systems and well corresponding distributions of binding sites and endogenous CGRP-like immunoreactivity.     

Analysis of trace element concentrations in the cerebrospinal fluid using particle-induced X-ray emission

The authors used for first time the PIXE method ("particle induced X-ray emission") for determination of the concentration of in the cerebrospinal fluid of neurological patients. In 40 hitherto examined patients with epilepsy, multiple sclerosis, extrapyramidal syndromes, Little's syndrome, Guillain-Barré syndrome, cerebral strokes, tumours of brain and spine, vasomotor headaches, neuralgia and discopathy, the concentration of the following trace elements was determined: Br, Zn, CU, Pb, Rb, Fe, Ca, K, Cl, Sr, Zr, Cr, Mn, Ni, As. The ranges of the determined concentrations in ppm units mean values and mutual relations of some elements were presented. The concentration of trace elements in cerebrospinal fluid was lower than in the tissues. The authors continue further investigations in many neurological syndromes with analysis of various clinico-laboratory correlations.     

Changes in serum and striatal free amino acids after Venezuelan equine encephalomyelitis virus infection

The infection with the Venezuelan equine encephalomyelitis virus produced a significant increase in the concentration of alanine, arginine, asparagine, glutamine, isoleucine, leucine, methionine, phenylalanine, threonine, tryptophan, tyrosine, and valine in the striatum of rats. On the contrary, the concentrations of aspartate, GABA, glutamate, and taurine were reduced. Arginine, aspartate, glycine, methionine, phenylalanine, taurine, and tyrosine concentrations were increased in the serum of infected rats. However, the modifications in the content of free amino acids in the striatum and serum of rats that survived the infection were qualitatively and quantitatively different from those detected during the acute phase of the infection.     

Topographic maps of brain electrical activity--pitfalls and precautions

Topographic mapping of brain electrical activity is a popular, powerful, and potentially misleading technique. The map lies at the end of a long chain of physiological, technical, electronic, and mathematical processes and is vulnerable to artifact, error, and distortion at many points. Close attention must be paid to data collection parameters, subject cooperation, minimization of artifact, limitations of resolutions, selection, and transformation of parameters for display, and map generation strategy to yield an accurate, physiologically interpretable map. Review of the data at each step of analysis, from the paper electroencephalogram (EEG) to sets of maps on video display, may be necessary for optimum understanding. Development of more sophisticated qualitative and quantitative concepts of "normal" physiology is needed. These improvements in electrophysiological data analysis demand, rather than obviate, sophistication on the part of the user.     

Consensus Paper: Pathological Role of the Cerebellum in Autism

There has been significant advancement in various aspects of scientific knowledge concerning the role of cerebellum in the etiopathogenesis of autism. In the current consensus paper, we will observe the diversity of opinions regarding the involvement of this important site in the pathology of autism. Recent emergent findings in literature related to cerebellar involvement in autism are discussed, including: cerebellar pathology, cerebellar imaging and symptom expression in autism, cerebellar genetics, cerebellar immune function, oxidative stress and mitochondrial dysfunction, GABAergic and glutamatergic systems, cholinergic, dopaminergic, serotonergic, and oxytocin-related changes in autism, motor control and cognitive deficits, cerebellar coordination of movements and cognition, gene-environment interactions, therapeutics in autism, and relevant animal models of autism. Points of consensus include presence of abnormal cerebellar anatomy, abnormal neurotransmitter systems, oxidative stress, cerebellar motor and cognitive deficits, and neuroinflammation in subjects with autism. Undefined areas or areas requiring further investigation include lack of treatment options for core symptoms of autism, vermal hypoplasia, and other vermal abnormalities as a consistent feature of autism, mechanisms underlying cerebellar contributions to cognition, and unknown mechanisms underlying neuroinflammation.

Comparative cytoarchitectonic study of gudden's tegmental nuclei in some mammals

The structure and location of the dorsal and ventral tegmental nuclei of Gudden were studied in brains of 12 species of mammals. The ventral teg-mental nucleus of Gudden is composed of oval or polygonal, medium-sized, well-stained cells, and includes the pars principalis situated ventral to the fasciculus longitudinalis medialis, and the pars suprafascicularis in the cen-tral gray matter dorsal to the fasciculus longitudinalis medialis (in the golden hamster, mouse, vole, and house shrew). The dorsal tegmental nucleus of Gudden is situated within the central gray matter. This nucleus includes the pars ventralis, composed of oval or triangular cells, medium-sized but smaller than those of the ventral tegmen-tal nucleus of Gudden, and the pars dorsalis, composed of round, small, and lightly stained cells, and often encapsulated by fibers of the fasciculus longi-tudinalis dorsalis. The isthmus between the dorsal and ventral tegmental nuclei of Gudden is distinct. In the cat, dog, rat, gerbil, and rabbit, the isthmus stands at the dorsal edge of the fasciculus longitudinalis medialis; in the golden hamster, mouse, vole, and house shrew, within the central gray matter; and in the guinea pig, at the ventral edge of the fasciculus longitudinalis medialis. In the green monkey and man, we could not find a ventral tegmental nucleus of Gudden, and in the house shrew and man, the pars ventralis and pars dor-salis of the dorsal tegmental nucleus of Gudden could not be separated.
