Neuroectodermal tumors of the peripheral and the central nervous system share neuroendocrine N-CAM-related antigens with small cell lung carcinomas

Summary The current study describes the presence of neuroendocrine antigens of peripheral and central neural tumors using eight monoclonal antibodies raised to small cell lung carcinoma (SCLC), which recognize neural/neuroendocrine or neural antigens, as defined by their reaction pattern in normal tissues and tumors. At least five of them recognize different epitopes of the neural cell adhesion molecule (N-CAM). It was found that all of 12 neuroblastomas, 2 ganglioneuroblastomas and 4 ganglioneuromas as well as 23 central primitive neuroectodermal tumors, 13 astrocytomas and 4 ependymomas share neural/neuroendocrine antigens (as defined by the anti-N-CAM antibodies Moc-1,-21,-32,-52 and-191) with SCLC. The neural/neuroendocrine antigen defined by Moc-171 was also found in all peripheral tumors, but only in further differentiated central tumors. Non-N-CAM related neural antigens (as defined by Moc-51 and-172) were found only in better-differentiated peripheral and central tumors, but they could be demonstrated in all three medulloblastoma cell lines studied. In addition, the antigen defined by Moc-51 was demonstrated in an immunoblot of a neuroblastoma cell line. Antibodies recognizing epithelia antigens of SCLC and other epithelia and their tumors (Moc-31 and-181) were non-reactive. It was concluded that these findings give further support for a relation between neural and neuroendocrine tumors and that some of the antibodies may be useful for the detection of differentiation in neural tumors. Antibodies with an epithelia recognition pattern may serve to distinguish neural from neuroendocrine tumors.Supported by NIH grant CA 36245 W.M.M. was a Fullbright scholar     

Assessment of complicance-related attitudes in psychiatry

Summary In a study of 118 psychiatric patients two questionnaires of similar content that are supposed to predict compliance with pharmacotherapy in psychiatry were examined, COSS and KK-Skala. These questionnaires assess the patient's attitudes towards his illness, pharmacotherapy, and the physician. Patient compliance was judged by the treating physicians. The results of discriminant analyses indicated that about two thirds of the patients were correctly classified into compliant and moderately or not compliant (as judged by the physicians) by means of COSS and KK-Skala, respectively. It is a matter for further research whether these results reflect in fact moderate associations between patient attitudes and compliant behavior or are due to limitations of the questionnaires and of the study design.     

DL-lysine-H3 uptake in “light” and “dark” neurons of the inferior olivary nucleus of euthyroid and dysthyroidal rats

Summary Uptake of DL-Lysine-H³ into light and dark cells of the rat inferior olivary nucleus was studied by radioautographiy. Uptake in light cells was higher than in dark cells and appears to be possibly related to the greater frequency of relationship with glial satellites. Dysthyroidal states were also observed to increase uptake of radioactivity which was prominently observed in hypothyroid rats. Since dark cells appear to take up less lysine than normal cells and are less frequently closely associated with glial satellites it is suggested these cells may represent a less physiologically active unit than the light cells rather than being simply artifactually produced by the procedures employed.

Zusammenfassung Die Aufnahme von DL-Lysin-H³ in hellen und dunklen Zellen im unteren Olivenkern der Ratte wurde mit Autoradiographie beobachtet. Die Aufnahme war höher in den hellen Zellen als in den dunklen, was möglicherweise mit einer größeren Häufigkeit von Glia-Satellit-Verbindungen in Zusammenhang gebracht werden könnte. Veränderungen im hormonalen Zustand der Schilddrüse konnten auch dazu beitragen, die Aufnahme von Radioaktivität zu erhöhen, was besonders bei Ratten mit niedriger Schilddrüsenaktivität hervortrat. Da dunkle Zellen offenbar weniger Lysin aufnehmen als normale Zellen, und sie seltener mit Glia-Satelliten verbunden sind, wird angenommen, daß diese Zellen möglicherweise eine weniger aktive physiologische Einheit darstellen als die hellen Zellen und daß es sich nicht einfach um ein Kunstprodukt handelt.

Does social deprivation during gestation and early life predispose to later schizophrenia?

Summary We employed a case-control study design to investigate whether schizophrenic patients differed from non-psychotic psychiatric patients in terms of place of birth and paternal occupation. Cases were first-contact schizophrenic patients ascertained from the Camberwell Cumulative Psychiatric Case Register. Controls were the next (non-psychotic) patient on the Register matched for age and sex. In comparison with controls, cases were more likely to have: (1) been born in the deprived innercity Camberwell catchment area (odds ratio 2.3), and (2) had fathers who had manual as opposed to non-manual occupations (odds ratio 2.1). The results were compatible with the notion that socio-economic deprivation during gestation and early life predisposes to later schizophrenia.     

Styles of Case Management: The Philosophy and Practice of Case Managers

A great deal of discussion and research has gone into defining and clarifying the role of case manager (CM) for persons with severe mental illness. This three state survey examines the philosophy and activities of practicing CMs in an attempt to identify current styles of case management. A cluster analysis based on CM rankings of five CM functions suggested four styles of case management: supportive social worker, individual therapist, therapist broker, and community advocate. Overall, CMs rated supportive interventions as most important and formal psychotherapy as relatively unimportant. CM style was related to CM activity (i.e., distribution of effort). Differences between states are noted and implications for future research are discussed.     

Hyperkinetic children: Early indicators of potential school failure

Hyperkinetic children are identified as a population-at risk upon admission to kindergarten. The etiology of hyperkinetic behavior is controversial. Organic driveness, hyperkinetic behavior disorder, postencephalitic behavior, brain damage with behavioral and conceptual deficit, Strauss syndrome, have all been used to label essentially similar symptom constellations. Bypassing the area of controversy, a study is reported that demonstrates that children who were identified as hyperkinetic (using behavioral criteria developed in an earlier study) were (1) absent from school more frequently, and (2) did remarkably less well on standardized tests of school readiness than their peers rated nonhyperkinetic. The implications are discussed and suggestions made for the development of intervention programs.An earlier version of this paper was presented at the Annual Meeting of the American Orthopsychiatric Association, March, 1967.     

AMP-rated psychopathology in chronic alcoholics

Summary In a group of 39 alcoholics within a withdrawal process, the psychical situation was rated using AMP scales (Angst et al. 1969). Cluster analysis of the items rendered the following five-cluster solution: (1) aggressive-depressive patients, (2) less impaired persons, (3) slowed persons with diminished contact, (4) emotionally inadequate persons, (5) appealing depressive persons. These results are discussed with respect to other data from clinical history and diagnostic findings.Supported by Deutsche Forschungsgemeinschaft, Sonderforschungsbereich 115, Teilprojekt C21     

Cortical regulation of subcortical dopamine systems and its possible relevance to schizophrenia

Summary A unique model of DA system regulation is presented, in which tonic steady-state DA levels in the ECF act to down-regulate the response of the system to pulsatile DA released by DA cell action potential generation. This type of regulation is similar in many respects to the phenomenon proposed to mediate the action of norepinephrine on target neurons; i.e., an increase in the signal-to-noise ratio as measured by postsynaptic cell firing (Freedman et al., 1977; Woodward et al., 1979). However, in this model the signal and the noise are neurochemical rather than electrophysiological. Furthermore, the noise (tonic DA in the ECF) actually down-regulates the signal (phasic DA release) directly, and thereby provides a signal of its own that affects the system over a longer time-course. Therefore, the difference between signal and noise may also depend on the time frame under which such determinations are made.     

Diagnosing Depression in African Americans

Since the 1970s, articles have noted the increased presence of psychotic symptoms among depressed African Americans, the presence of diagnostic bias identified when structured clinical interviews are used, and the identification of misdiagnosis of affective illness among chronically, mentally ill, African Americans. This paper reviews this literature and describes three alternative presentations of depressive illness among African Americans that differ from the DSM IV criteria for Major Depressive Disorder: the stoic believer, the angry, evil one with a personality change, and the John Henry doer. Clinicians are encouraged to recall these presentations of depression when evaluating African American patients.     

Ultrastructural changes in the anterior horn synapses of rat spinal cord under different locomotor conditions

Summary Ultrastructural changes in axodendritic synapses of the spinal cord ventral horn are studied in rats subjected to different locomotor conditions: immobilization, control and physical loading. Enhanced motor activity results in a reduction of the number of synaptic vesicles in the axon terminal, as well as flattening and diminution of their size. Other changes correlated with the different motor regimes are likewise established in the number of terminal ending's mitochondria, in active zones, in subjunctional dense bodies, and in the bouton area. Data are treated by means of variation analysis. The significance of differences is established by T-criterion.     

A comparative immunohistochemical study on striatal Met-enkephalin expression in Alzheimer's disease and in progressive supranuclear palsy

Summary Using a sensitive immunoperoxidase technique we examined Met-enkephalin (MEnk) expression in the striatum and globus pallidus external segment (GPe) from patients with Alzheimer's disease (AD) and with progressive supranuclear palsy (PSP). In AD patients strong MEnk-like immunoreactivity was persistent in the striatum showing so-called striosomes. In addition, a number of typical woolly fibers were observed in the GPe. MEnk-positive striosomes were also visible in the striatum of PSP patients and were similar to those of normal controls and of AD patients. However, the MEnk-positive woolly fibers appcarance was less well recognizable in the GPe from all the PSP patients examined.     

Serum creatine kinase B subunit levels in neurogenic atrophies

Summary This study is an attempt to determine the creatine kinase B (CK-B) subunit levels in neurogenic atrophies. A group of 69 patients was studied and the results were compared with those in a group of 32 patients with muscle disease. The results showed that the CK-B levels are considerably higher in patients with amyotrophic lateral sclerosis (P<0.001) and peroneal muscular atrophy (P<0.001). Further studies in the various subgroups of neurogenic atrophies showed that, regardless of the nosological entity, the CK-B activity is considerably higher: (1) in the widespread as opposed to limited forms (P<0.001); (2) in the chronic than in the acute neurogenic atrophies (P<0.001); and (3) in the active as opposed to residual forms (P<0.02). It is suggested that the increase of CK-B in neurogenic atrophies is a strong indication of an active regeneration process in the denervated muscle.     

Soviet psychotherapy: The tasks and methodological problems

Soviet psychotherapy follows Western European traditional pre-psychoanalytical rationalistic methodology. On the other hand, Soviet therapists assign great importance to clinical diagnosis within the framework of the classical scheme of Kraepelin. Finally, methods close to behavior therapy, especially so-called training approaches, are popular.     

Lack of correlation between DST results and urinary MHPG in depressed inpatients

Summary Abnormalities of noradrenaline metabolism and of the activity of hypothalamic-pituitary adrenal axis (HPA) have been reported in depression. To study the possible relationship between these 2 parameters, urinary excretion of 3-methoxy-4-hydroxy-phenylethyleneglycol (MHPG) and Dexamethasone Suppression Test (DST) were analyzed in 58 depressed patients. A positive correlation was found between the age of depressed patients and 24-h urinary excretion of MHPG. Twenty-two patients (38%) were DST non suppressors. Pre-DST plasma cortisol levels were significantly higher in non suppressors than suppressors. No difference was found however between urinary MHPG levels in supressors and non suppressors. There was no correlation between pre-DST plasma cortisol and levels of urinary excretion of MHPG. These results do not support the hypothesis of a relationship between these 2 parameters. However, when depressed patients were separated into two groups according to urinary excretion of MHPG (high MHPG and low MHPG), the high MHPG group included significantly more non suppressors then the low MHPG one. This result is not sufficient to demonstrate of link between HPA system activity and central noradrenaline metabolism.     

Visual pattern evoked responses and blink reflexes in assessment of MS diagnosis

Summary VEPs were measured after pattern reversal in 135 MS patients and 30 control subjects. Neurological findings were documented in a standard manner. An extensive ophthalmological examination of all subjects was part of the study. The latency of P₂ was abnormally delayed in 82% of the definite, in 60% of the probable and in 65% of the possible MS groups respectively. The VEP was more often delayed in relation to ophthalmological disturbances. Changes in the MS classification had to be made in more than 10% of the patients, due to delay of VEP latency. These were patients with a spinal form of MS, which is known to create diagnostic problems.Optically and electrically evoked blink reflexes were recorded in 107 MS patients. All patients with mesencephalic lesions had delayed responses of the optically evoked reflex. 74% of the patients with caudal brainstem lesions had delayed latencies of the components of the electrically evoked blink reflex. The blink reflex was delayed in 18 additional patients without brainstem signs. The possibility of delineating clinically silent brainstem lesions by investigating blink reflexes is discussed.Supported by the Deutsche Forschungsgemeinschaft (Dr. Fischer Bosch-Stiftung).     

Cognitive functioning in female patients with 21-hydroxylase deficiency

The cognitive functioning of 27 female patients with congenital adrenal hyperplasia (CAH) (aged 11–41 yrs) and 13 of their healthy sisters (13–31 yrs) was compared using short versions of age-appropriate Wechsler scales. In contrast to other studies, neither a higher than average IQ level for CAH patients (mean: 99.0) nor for their sisters (97.7) was found. Unexpectedly, and in contrast to other reports, the subgroup of salt-wasting (SW) patients>16 yrs (N=6; mean score: 111.5) differed from their sisters as well as from simple-virilizing (SV) patients in full IQ (p<0.05) and subtest scorings for Information, Similarities, and Picture Completion (p<0.05–<0.10). SW patients displayed more masculine behaviour (vs. SV patients and sisters) which, in turn, was related to differential prenatal hormonal influences. No clear-cut relationships between IQ/cognitive (subtest) findings and gender-role behaviour were found.

Zusammenfassung 27 Patientinnen mit dem Adrenogenitalen Syndrom (AGS) (11–41 J.) und 13 ihrer Schwestern (13–31 J.) wurden hinsichtlich intellektueller Funktionen verglichen (Kurzformen von HAWIK, HAWIE). Im Unterschied zu den meisten früheren Untersuchungen wurden weder für Patientinnen (mean: 99.0) noch für Kontrollen (97.7) über dem Durchschnitt liegende IQ-Werte gefunden. Im Gegensatz zur Literatur unterschied sich die Teilgruppe der Salzverlust-Patientinnen (SW)>16 J. (N=6, mean: 111.5) von den Schwestern und den Patientinnen mit einfachem AGS (SV) im Gesamt-IQ (p<0.05) und in den Untertests Allgemeines Wissen, Gemeinsamkeiten und Bilderergänzen (p<0.05–<0.10). SW-Patientinnen hatten signifikant männlichere Verhaltensmuster gezeigt (vs. SV-Patientinnen und Schwestern), die auf differentielle Hormoneffekte pränatal bezogen worden waren. Es fanden sich aber keine klaren Zusammenhänge zwischen IQ-bzw. Untertest-Resultaten und Ergebnissen für Geschlechtsrollenverhalten.

Résumé Le fonctionnement cognitif de 21 patientes avec une hyperplasie congénitale surrénale (âgée de 11 à 41 ans) et de 13 de leurs soeurs saines (13–31 ans) a été comparé au moyen de versions raccourcies de l'échelle de Wechsler appropriée à l'âge. En contraste avec d'autres études, il n'a été retrouvé un Q.I. plus haut que la moyenne ni pour les patientes (moyenne 99.0) ni pour leurs soeurs (moyenne 97.7). De façon inattendue, et en contraste avec d'autres études, le sous-groupe de patientes déprivées en sel (SW)>16 ans (N=6), moyenne score: 111.5) différait de leurs soeurs aussi bien en tant que patientes présentant des signes de virilsation (SV) pour le Q.I. complet (p<0.05) et les scores aux subtests d'information, de similarité et de complément d'images (p<0.05–0.10). Les patientes déprivées en sel (SW) montraient un comportement plus masculin (vs. SV et leurs soeurs) qui en retour était relié aux influences hormonales prénatales différentes. Il n'y avait pas de relation de différences nettes entre les résultats aux sous-tests cognitifs du Q.I. et le comportement de genre.

     

Extraocular muscles light microscopy and ultrastructural features

Summary Thirty extraocular muscles (EOM) from 20 patients were evaluated by light microscopy (LM), electron microscopy (EM), and enzyme histochemistry (EZH). Twenty-one EOM were obtained from 13 patients with strabismus, 9 EOM from 4 patients undergoing eye surgery for other reasons and from 3 autopsy cases. One m thick sections revealed marked variation in muscle fibre shape and size and in myofibrillar structure; also noted were small, hypertrophied, whorled, and ringbinden fibres. Dense and granular material in the central portion of some fibres and sarcomere disruption in 2–3 m sections was observed. EZH revealed the absence of the classical mosaic pattern usually found in skeletal muscles. ATPase studies were inconsistent and did not correlate with the expected reciprocal activity of NAD-H diaphorase, particularly on the large fibres.Ultrastructural features consisted of vacuoles within myofilament bundles, smearing of Z bands, and nemaline rods. Occasional myelin figures and lipid-like droplets were observed in subsarcolemmal spaces, associated with scattered clusters of glycogen granules. Abnormal mitochondria and subsarcolemmal inclusions of dense and granular material were conspicuous. Leptomeric profiles, Zebra bodies, or striated bodies were noted in 8 EOM's, and an Hirano body was found in 1. The intramuscular nerves contained structures resembling Luse bodies in 7 cases.These observations suggest that EOM from individuals with and without strabismus possess unique structural characteristics suggestive of developmental and morphological disarrangement of contractile elements. Some of these changes might play a role in the pathogenesis of strabismus and in the development of clinical symptoms.These features are significantly different from striated skeletal muscle. Therefore the criteria used in the pathological evaluation and diagnosis of skeletal muscle disorders cannot be unequivocally applied to EOM investigations. These data establish the necessity to determine histological norms, ultrastructural patterns, and develop new enzyme histochemistry criteria for the evaluation of EOM. Only then can an acceptable comparison of EOM and skeletal muscle be made.     

Relationship of maternal parenting behaviors to preschool children's temperament

Mothers of 182 preschool nursery school children rated their own parenting responses on a Parent's Report questionnaire. At the same time the mothers responded to the Behavior Style Questionnaire (BSQ) from which scores were determined for nine categories of temperament. On the basis of category scores the children were grouped into one of five temperament clusters i.e. easy, difficult, slow to warm up, high intermediate, low intermediate. The children's membership in BSQ clusters was independent of sex, age, birth order, and mothers employment status but there was a significantly higher ratio of easy children from higher socioeconomic classes I and II. Mothers of children grouped in either the difficult or slow to warmup clusters were more likely to use guilt inducing and temper-detachment parenting styles than mothers of children grouped in the easy cluster.     

Mind-Body Innovations—An Integrative Care Approach

Integration of behavioral health and medicine has gained increased support recently within the new field of complementary medicine. Providers from both disciplines are acknowledging the mind-body connection and recognizing the value of treating the whole patient through working within an integrative delivery model. This paper describes two treatment programs which were developed using the principles of the mind-body connection and implemented within an integrative setting at a large HMO. The results of research studies are presented and discussed to demonstrate the efficacy of these programs.     

Depression in Parkinson disease: a disabling but neglected factor

20 depressed and 20 non depressed patients with Parkinson disease were rated for disability on the Northwestern University Disability Scale and for severity of the typical motor symptoms on the Columbia University Rating Scale and were assessed for mental deterioration. The severity of the typical symptoms was practically equivalent in the two groups but the depressed patients not only presented mild mental deterioration but were significantly more disabled (less independent) than the patients without depression. A significant correlation was found between severity of depression and degree of disability but not between severity of depression and severity of typical motor symptoms. Depression was diagnosed much later than the typical symptoms. Only 25% of the depressed parkinsonians had received tricyclic antidepressants, about 20% had been treated with dopamine-antagonist psychotropic drugs and some 50% had received no treatment at all against depression. Timely diagnosis and appropriate treatment of depression in parkinsonian patients limits the effects of a major disabling factor.Party supported by Regione Piemonte, grant n. 17
