A total of 402 patients were followed up for, on average, 25 years after the onset of their illness. The diagnoses, made longitudinally, were as follows: schizophrenic disorder (n = 148); schizoaffective disorder (n = 101); affective disorder (n = 106). The remaining 47 patients did not fulfil the criteria for any of these diagnoses. A distinction was made between "episode" (cross-sectional diagnosis) and "illness" or "disorder" (longitudinal diagnosis). The "episodes" (cross-sectional diagnosis) were classified according to slightly modified DSM-III criteria into schizophrenic, affective (melancholic, manic, manic-depressive mixed), schizoaffective (schizodepressive, schizomanic, schizomanic-depressive mixed) and non-characteristic episodes. The criteria for the episodes are: Schizophrenic episode: criteria of DSM-III, slightly modified. Melancholic episode: according to "Major Depression, Melancholic Type" of DSM-III-R. Manic episode: according to the criteria of DSM-III, slightly modified. Manic-depressive mixed episode: Presence of manic and depressive symptomatology during one episode. Schizodepressive episode: Presence of schizophrenic and depressive symptomatology during one episode. --Schizomanic episode: presence of schizophrenic and manic symptomatology during one episode. Schizomanic-depressive mixed episode: Presence of schizophrenic, manic and depressive symptomatology during one episode. The diagnosis of an "illness" or "disorder" (longitudinal diagnosis) took account of all the kinds of episodes that occurred during the whole course. The final diagnosis (longitudinal diagnoses) were defined as follows: Schizophrenic disorder: only schizophrenic episodes during the whole course Affective disorder: only affective episodes during the whole course (melancholic, manic, manic-depressive mixed episodes). Schizoaffective disorder: at least one schizoaffective episode during the course (schizodepressive, schizomanic, schizomanic-depressive mixed episode), independently of the type and number of other episodes, or sequential manifestation of schizophrenic and affective episodes. The principal instruments of investigation and evaluation were: Global Assessment Scale (GAS); Disability Assessment Schedule (WHO/DAS); Psychological Impairment Rating Schedule (WHO/PIRS); Present State Examination (PSE); Criteria for social class and social mobility according to Kleining and Moore (also transferred to the criteria of Hollingshead and Redlich) - A pool of items based on WHO instruments for social parameters; Items for pharmacological treatment and prophylaxis.

A therapeutic tool which assists in identifying the client's experience of depression would offer many virtues, particularly if that tool helped to break the experience down into more manageable elements for both client and therapist. In this article, Nicholas Holdsworth and Gordon Moore describe how it is possible to translate the results of the Beck Depression Inventory and the Coping Responses Questionnaire into complementary bar graphs which go some way to providing a baseline for therapeutic progress.

Angiogenin transiently depresses the cAMP level of rat aortic smooth muscle cells. The dose response is similar to angiogenin activation of the inositol-specific phospholipase C in this cell line [Moore, F. & Riordan, J.F. (1989) Biochemistry. Submitted]. The time course showed a maximal depression (28%) in cAMP at 2 min, followed by a return to that of unstimulated cells by 3.5 min. Angiogenin also inhibited isoproterenol stimulated cAMP formation, but the percentage depression in cAMP (9%) was less than that in cells treated with angiogenin alone (28%). In contrast angiogenin enhanced forskolin stimulation of adenylate cyclase, an effect previously linked with agonist activation of protein kinase C. The effect of angiogenin on cellular cAMP was abolished by pre-incubation with pertussis toxin. Angiogenin had no effect on cellular cGMP. These results are consistent with activation of adenylate cyclase Gi following exposure of the cells to angiogenin and provide further evidence for interaction between cellular signalling pathways.

Several hepatotoxic agents with varied chemical mechanisms of toxicity (acetaminophen, diquat, and CCl4) depress membrane calcium pumps and/or enhance the permeability of membranes to calcium. To probe the relevance of these findings to maintenance of calcium homeostasis after toxins in vivo, we measured the activity of glycogen phosphorylase a, as an index of cytosolic free [Ca2+], in freeze-clamped liver samples obtained at several times after the toxin dose. Both acetaminophen and diquat caused significant increases of phosphorylase a activity, and activity remained elevated for several hours after the dose. Significantly, the administration prior to diquat of desferrioxamine, which offers protection against the liver necrosis and depression of microsomal Ca2+ accumulation observed after diquat alone (Tsokos-Kuhn et al., Mol Pharmacol 34: 209-214, 1988), decreased phosphorylase activation. Activation of phosphorylase was observed also after CCl4 administration, as previously reported by Long and Moore (Biochem Pharmacol 35: 4131-4137, 1986). We conclude that perturbations in liver membrane Ca2+ regulation observed after administration of these hepatotoxins in vivo correlate directly with phosphorylase a activity, thereby providing additional in vivo evidence for an alteration of Ca2+ homeostasis early in the development of the liver damage produced by these chemicals.

Tibial plateau fractures with depression of posterior aspects of the proximal tibia cause significant therapeutic problems. Posterior fractures on the medial side are mainly highly instable fracture-dislocations (Moore type I). Posterolateral fractures usually cause massive depression and destruction of the chondral surface. Surgical exposure of these fractures from anterior requires major soft tissue dissection and has a significant complication rate. However, incomplete restoration of the joint surface results in chronic postero-inferior joint subluxation, osteoarthritis and pain. We present new specific approaches for posterior fracture types avoiding large skin incisions, but allowing for atraumatic exposure, reduction and fixation. Posteromedial fracture-dislocations are exposed by a direct posteromedial skin incision and a deep incision between medial collateral ligament and posterior oblique ligament. The posteromedial pillar and the posterior flare of the proximal tibia are visualized. The inferior extent of the joint fragment can be reduced by indirect techniques or direct manipulation of the fragment. Fixation is achieved with subchondral lag screws and an anti-glide plate at the tip of the fragment. Posterolateral fractures are exposed by a transfibular approach: the skin is incised laterally, the peroneal nerve is dissected free. The fibula neck is osteotomized, the tibiofibular syndesmosis is divided and the fibula neck is reflected upwards in one layer with the meniscotibial ligament and the iliotibial tract attachment. Reflexion of the fibula head relaxes the lateral collateral ligament, allows for lateral joint opening and internal rotation of the tibia and thus exposes the posterolateral and posterior aspect of the tibial plateau. Fixation and buttressing on the posterolateral side can be achieved easily with this approach. In closure, the fibula head is fixed back with a lag screw or a tension-band system. These two exposures can be combined in bicondylar posterior fracture situations. 168 cases with tibial plateau fractures had ORIF in the authors' institution from 1988 to 1994. 26 of these patients had a total of 29 posterior exposures to treat their fractures (9 posteromedial, 12 posterolateral, 3 combined posteromedial/posterolateral and 2 posterior/anterior exposures). No specific complications occurred related to these exposures, i.e. no skin slough, no infection, no nerve palsy. The mean duration of follow-up was 4 years. Twenty-one cases healed uneventfully: 12 were excellent in Rasmussen's clinical score, 8 were good and 1 was fair. Seven patients were excellent in the radiological score, 13 good and 1 fair. Five of the 26 cases had revision surgery: 3 patients developed valgus or retrocurvatum deformity and were successfully treated by an osteotomy. They obtained a good result at follow-up. Two fractures in elderly patients were revised to an endoprosthesis.

Sustained inward currents in neuronal membranes underlie tonic-clonic seizure discharges and spreading depression (SD). It is not known whether these currents flow through abnormally operating physiological ion channels or through pathological pathways that are not normally present. We have now used the NEURON simulating environment of Hines, Moore, and Carnevale to model seizure discharges and SD. The geometry and electrotonic properties of the model neuron conformed to a hippocampal pyramidal cell. Voltage-controlled transient and persistent sodium currents (I(Na,T) and I(Na,P)), potassium currents (I(K,DR) and I(K,A)), and N-methyl-D-aspartate (NMDA) receptor-controlled currents (I(NMDA)), were inserted in the appropriate regions of the model cell. The neuron was surrounded by an interstitial space where extracellular potassium and sodium concentration ([K(+)](o) and [Na(+)](o)) could rise or fall. Changes in intra- and extracellular ion concentrations and the resulting shifts in the driving force for ionic currents were continuously computed based on the amount of current flowing through the membrane. A Na-K exchange pump operated to restore ion balances. In addition, extracellular potassium concentration, [K(+)](o), was also controlled by a "glial" uptake function. Parameters were chosen to resemble experimental data. As long as [K(+)](o) was kept within limits by the activity of the Na-K pump and the "glial" uptake, a depolarizing current pulse applied to the cell soma evoked repetitive firing that ceased when the stimulating current stopped. If, however, [K(+)](o) was allowed to rise, then a brief pulse provoked firing that outlasted the stimulus. At the termination of such a burst, the cell hyperpolarized and then slowly depolarized and another burst erupted without outside intervention. Such "clonic" bursting could continue indefinitely maintained by an interplay of the rise and fall of potassium and sodium concentrations with membrane currents and threshold levels. SD-like depolarization could be produced in two ways, 1) by a dendritic NMDA-controlled current. Glutamate was assumed to be released in response to rising [K(+)](o). And 2) by the persistent (i.e., slowly inactivating) Na-current, I(Na,P). When both I(NMDA) and I(Na,P) were present, the two acted synergistically. We conclude that epileptiform neuronal behavior and SD-like depolarization can be generated by the feedback of ion currents that change ion concentrations, which, in turn, influence ion currents and membrane potentials. The normal stability of brain function must depend on the efficient control of ion activities, especially that of [K(+)](o).

The treatment of chronic and recurrent depression is a priority for the development of new interventions. The maintenance of residual symptoms following acute treatment for depression is a risk factor for both chronic depression and further relapse/recurrence. This open case series provides the first data on a cognitive-behavioural treatment for residual depression that explicitly targets depressive rumination. Rumination has been identified as a key factor in the onset and maintenance of depression, which is found to remain elevated following remission from depression. Fourteen consecutively recruited participants meeting criteria for medication--refractory residual depression [Paykel, E.S., Scott, J., Teasdale, J.D., Johnson, A.L., Garland, A., Moore, R. et al., 1999. Prevention of relapse in residual depression by cognitive therapy--a controlled trial. Archives of General Psychiatry 56, 829-835] were treated individually for up to 12 weekly 60-min sessions. Treatment specifically focused on switching patients from less helpful to more helpful styles of thinking through the use of functional analysis, experiential/imagery exercises and behavioural experiments. Treatment produced significant improvements in depressive symptoms, rumination and co-morbid disorders: 71% responded (50% reduction on Hamilton Depression Rating Scale) and 50% achieved full remission. Treating depressive rumination appears to yield generalised improvement in depression and co-morbidity. This study provides preliminary evidence that rumination-focused CBT may be an efficacious treatment for medication--refractory residual depression.

In a manner unique among activity-regulated immediate early genes (IEGs), mRNA encoded by Arc (also known as Arg3.1) undergoes rapid transport to dendrites and local synaptic translation. Despite this intrinsic appeal, relatively little is known about the neuronal and behavioral functions of Arc or its molecular mechanisms of action. Here, we attempt to distill recent advances on Arc spanning its transcriptional and translational regulation, the functions of the Arc protein in multiple forms of neuronal plasticity [long-term potentiation (LTP), long-term depression (LTD), and homeostatic plasticity], and its broader role in neural networks of behaving animals. Worley and colleagues have shown that Arc interacts with endophilin and dynamin, creating a postsynaptic trafficking endosome that selectively modifies the expression of AMPA-type glutamate receptors at the excitatory synapses. Both LTD and homeostatic plasticity in the hippocampus are critically dependent on Arc-mediated endocytosis of AMPA receptors. LTD evoked by activation of metabotropic glutamate receptors depends on rapid Arc translation controlled by elongation factor 2. Bramham and colleagues have shown that sustained translation of newly induced Arc mRNA is necessary for cofilin phosphorylation and stable expansion of the F-actin cytoskeleton underlying LTP consolidation in the dentate gyrus of live rats. In addition to regulating F-actin, Arc synthesis maintains the activity of key translation factors during LTP consolidation. This process of Arc-dependent consolidation is activated by the secretory neurotrophin, BDNF. Moore and colleagues have shown that Arc mRNA is a natural target for nonsense-mediated mRNA decay (NMD) by virtue of its two conserved 3'-UTR introns. NMD and other related translation-dependent mRNA decay mechanisms may serve as critical brakes on protein expression that contribute to the fine spatial-temporal control of Arc synthesis. In studies in behaving rats, Guzowski and colleagues have shown that location-specific firing of CA3 and CA1 hippocampal neurons in the presence of theta rhythm provides the necessary stimuli for activation of Arc transcription. The impact of Arc transcription in memory processes may depend on the specific context of coexpressed IEGs, in addition to posttranscriptional regulation of Arc by neuromodulatory inputs from the amygdala and other brain regions. In sum, Arc is emerging as a versatile, finely tuned system capable of coupling changes in neuronal activity patterns to diverse forms of synaptic plasticity, thereby optimizing information storage in active networks.

In this article, we report the results of 3 studies evaluating the psychometric properties of scores generated using the Erikson Psychosocial Stage Inventory (EPSI; Rosenthal, Gurney, & Moore, 1981) with emerging adults. In Study 1, a hybrid bifactor solution, consisting of an overall identity factor as well as of "method effects" factors for identity synthesis and identity confusion, provided a better fit to the data than did either one or two-factor solutions. This bifactor solution was largely invariant across gender and across Whites, Blacks, and Hispanics. In Study 2, the overall identity, identity synthesis, and identity confusion scores were shown to possess convergent validity with another Eriksonian measure and with measures of identity status. In Study 3, the EPSI subscale scores were shown to possess construct validity vis-a-vis self-esteem, purpose in life, internal locus of control, ego strength, anxiety, and depression. We discuss implications for the measurement of identity.

Workaholism surfaced some years ago as a veritable addiction in the wide sense of the term, dependence. It differs from other sorts of dependence in that it is very often viewed in a positive perspective in the sense that it conveys to the person concerned the illusion of well-being, as well as a motivation and dedication in their professional activity. During the past 30 years, several authors have attempted to define this concept and to determine its characteristics. Robinson believes that workaholics have an approach to life whereby their work feeds on time, energy and physical activity. This provokes consequences that affect their physical health and interpersonal relationships. They have a tendency to live in the future rather than in the present. For Scott, Moore and Micelli , the compulsion for work is not necessarily viewed as being detrimental to one's health. Spence and Robbins highlight the notion of the pleasure experienced at work in their theoretical approach. The prevalence of the dependence on work is estimated at between 27 and 30% in the general population. It is correlated to the number of hours of work per week and tends to be higher as annual revenue increases. The sex ratio is 1, and the parents of children 5 to 18 years of age are the most susceptible to considering themselves workaholics. The physical and psychological consequences of professional exhaustion are characterized primarily by the decrease in self-esteem, symptoms of fatigue, anxiety, depression, irritability and the manifestation of physical problems including cardiovascular ailments, as evidenced by hypertension, as well as heart and kidney complications. All the theoretical point of views, from the psychoanalytical models to the contemporary models, highlight self esteem as being the centerpiece of the question regarding the problem of workaholism. In fact, the narcissism articulated from the sociological evolution of our western way of life permits us to delineate the psychic identity of the individual better, and therefore, to understand this reconstructive attempt of one's self better. In characterizing the personality traits of workaholic individuals, the doctor/therapist is required to deal with this new form of dependence as early as possible, in order to anticipate and avert the numerous personal, professional, social, relational and sanitary complications. Faced with this large prevalence of dependence on work, it seems important to us to look for a symptomatology that would emanate a signal of workaholism so as to envisage and propose to workaholic patients a specific course of action that would be adapted to their needs.
