The relatively recent development of the psychosocial rehabilitation has its origins mainly in the progress of modern psychopharmacology, the assertion of the rights of the patients and the result of the studies showing that the evolution of persons suffering from severe and persistent mental illnesses can prove to be positive in many cases. In spite of the heterogeneity of the experiences and of the theoretical references, the core principles of the psychosocial rehabilitation imposed themselves. These principles can be classified according to three levels, that of relational ethics, that of the method of intervention and that of the institutional device. A recent study showed that 2.4@1000 of the general adult population of the Canton of Vaud live in sociotherapeutic and rehabilitation accommodations. In this sample, there is a important percentage of relatively young persons (55.3% are under 40). In institutional accommodation there is a majority of patients suffering from major personality disorders and addiction (40.6%), followed by psychotic disorders (37.2%), persistent mood disorders (12.3%), neurotic disorders (6.6%) and psycho-organic disorders (3.3%). In home based rehabilitation, the ratio of patients with psychotic disorders is more important (53.1%). This difference would indicate that people with schizophrenia would have a better social outcome than personality disorders with addiction

Rectal diazepam is widely used in the treatment of acute seizures in children but has some disadvantages. Nasal/sublingual midazolam administration has been recently investigated for this purpose but never at home or in a general paediatric hospital. The aim of this open study was to determine the efficacy, the tolerance and the applicability of nasal midazolam during acute seizures in children both in hospital and at home. We included known epileptic children for treatment at home and all children with acute seizures in the hospital. In all, 26 children were enrolled, 11 at home and 17 in the hospital (including two treated in both locations); only one had simple febrile seizure. They had a total of 125 seizures; 122 seizures (98%) stopped within 10 minutes (average 3.6 minutes). Two patients in the hospital did not respond and in three, seizures recurred within 3 hours. None had serious adverse effects. Parents had no difficulties administering the drug at home. Most of those who were using rectal diazepam found that nasal midazolam was easier to use and that postictal recovery was faster. Among 15 children who received the drug under electroencephalogram monitoring (six without clinical seizures), the paroxysmal activity disappeared in ten and decreased in three. Nasal midazolam is efficient in the treatment of acute seizures. It appears to be safe and most useful outside the hospital in severe epilepsies, particularly in older children because it is easy for parents to use. These data should be confirmed in a larger sample of children. Its usefulness in febrile convulsions also remains to be evaluated.

Summary Mood disorders are among the most prevalent, psychosocial^ debilitating, chronic and relapsing forms of psychiatric illnesses. Despite considerable advances in their characterization, the heterogeneous nature of susceptibility factors and patient's symptoms could account for the lack of totally effective and remissive treatment. The neurobiological hypothesis of mood disorders etiology has evolved since the monoamine and neurotrophin theories and current evidence is pointing toward their integration in a broader polygenic epistatic model resulting in defective neuroplasticity of circuitries involved in emotion processing. Consequently, the unraveling of molecular underpinning pathways involved in neuronal plasticity, commonly altered among mood disorder syndromes and symptoms, should shed light on their etiology and provide new drug target. The transcription factor CREB has been critically involved in the long-lasting forms of neuronal plasticity and in the regulation of several mood disorders susceptibility genes. In addition, altered CREB activity has been associated with mood disorders pathophysiology and pharmacotherapy. Interestingly, the newly-identified protein CREB-regulated transcription coactivator 1 (CRTC1) was shown by previous studies in the laboratory to be a neuroactivity- dependent cAMP and calcium sensor, a potent activator of CREB-dependent transcription and involved in neuroplasticity mechanisms associated with long-term synaptic potentiation. Furthermore, the major mood disorder susceptibility gene Bdnf was suggested to be transcriptional regulated by CRTC1. Therefore, we aimed to investigate a role for CRTC1 in mood disorders by generating and characterizing a Crtcl deficient mouse model at the behavioral and molecular levels. Interestingly, their comprehensive characterization revealed a behavioral profile mirroring several major symptoms comorbid in mood disorders, including altered social interactions, aggressive behaviors, obesity, psychomotor retardation, increased emotional response to stress, decreased sexual drive and depression-like behaviors. To investigate the molecular mechanisms underlying these pathological behaviors and the implication of CRTC1 in the regulation of CREB-regulated genes in vivo, we also quantified transcript levels of several relevant CREB-regulated susceptibility genes in brain structures involved in the pathophysiology of mood disorders. Strikingly, we found the underexpression of primary components of the neurotrophin system: Bdnf and its cognate receptor TrkB, a marked decrease in the Nr4a family of transcription factors, implicated in neuroplasticity and associated with dopamine-related disorders, as well as in several other relevant CREB regulated genes. Moreover, neurochemical analysis revealed that Crtcl null mice presented alteration in prefrontal cortical monoamine turnover as well as in hippocampal and accumbal serotonin levels, similarly associated with mood disorders etiology and pharmacotherapy. Together, the present thesis supports the involvement of CRTC1 pathway hypofunction in the pathogenesis of mood disorders and specifically in pathological aggression, obesity and depression-related behavior comorbidities. Ultimately, CRTC1 may represent an interesting antidepressant, antiaggressive or mood stabilizer drug target candidate through the modulation of major CREB regulated susceptibility genes. Les troubles de l'humeur comptent parmi les maladies psychiatriques les plus prévalentes, psychosocialement débilitantes, chroniques et avec le plus grand risque de rechute. Malgré de considérable avancées dans leur caractérisation, la nature hétérogène des facteurs de susceptibilité et des symptômes présentés par les patients, semble justifier l'absence de traitement entraînant une rémission complète de la maladie. L'hypothèse de l'étiologie neurobiologique des troubles de l'humeur a évolué depuis la théorie des monoamines et des neurotrophines. Actuellement, elle tend à les englober dans un modèle polygénique épistatique induisant une déficience de la neuroplasticité des circuits impliqué dans la régulation des émotions. Par conséquent, il apparaît particulièrement relevant de caractériser des voies moléculaires impliquées dans la plasticité neuronale, communément altérées parmi les différents syndromes et symptômes des maladies de l'humeur, afin d'améliorer leur compréhension ainsi que de proposer de nouvelles cibles thérapeutiques potentielles. Le facteur de transcription CREB a été de façon répétée et cohérente impliqué dans les mécanismes à long terme de la plasticité neuronale, ainsi que dans la régulation de plusieurs gènes de susceptibilité aux maladies de l'humeur. De plus, une altération dans l'activité de CREB a été impliqué dans leur étiologie et pharmacothérapie. De façon intéressante, des résultats préliminaires sur la protéine récemment découverte CREB-regulated transcription coactivator 1 (CRTC1) ont indiqué que son activation était dépendante de l'activité neuronale, qu'il était un senseur du calcium et de l'AMPc, ainsi qu'un coactivateur de CREB requis et puissant impliqué dans les mécanismes de plasticité neuronale associés à la potentialisation à long terme. En outre, des résultats ont suggéré que le gène majeur de susceptibilité Bdnf est régulé par CRTC1. Ainsi, notre objectif a été d'investiguer un rôle éventuel de CRTC1 dans les maladies de l'humeur en générant et caractérisant une lignée de souris déficiente pour Crtcl, tant au niveau comportemental que moléculaire. De façon intéressante, leur caractérisation détaillée a révélé un profil comportemental reflétant de nombreux aspects des maladies de l'humeur incluant une altération des interactions sociales, une agression pathologique, l'obésité, un retard psychomoteur, une réponse émotionnelle au stress accrue, une diminution de la motivation sexuelle, et des comportements reliés à la dépression. Afin d'investiguer les mécanismes moléculaires sous- jacents cette altération du comportement, ainsi que l'implication de CRTC1 dans l'expression des gènes régulés par CREB in vivo, nous avons quantifié les niveaux de transcrits de plusieurs gènes de susceptibilité régulés par CREB et impliqués dans la physiopathologie des maladies de l'humeur. Remarquablement, nous avons trouvé la sous-expression de composants primordiaux du système neurotrophique: Bdnf et son récepteur TrkB, une diminution majeure de la famille des facteurs de transcription Nr4a, impliqués dans la neuroplasticité et associés à des désordres liés à la dopamine, ainsi que de nombreux autres gènes relevants régulés par CREB. De plus, une analyse neurochimique a révélé que les souris déficientes pour Crtcî présentent une altération du turn-over des monoamines du cortex préfrontal ainsi que des niveaux hippocampaux et accumbaux de sérotonine, associés de façon similaire dans l'étiologie et la pharmacothérapie des maladies de l'humeur. Vue dans son ensemble, la présente thèse supporte l'implication d'une sous-régulation de la voie de CRTCI dans la pathogenèse des maladies de l'humeur ainsi que dans la comorbidité de l'agression pathologique, l'obésité et la dépression. En conclusion, CRTCI pourrait représenter une cible médicamenteuse intéressante aux propriétés antidépressante, antiagressive ou stabilisatrice de l'humeur au travers de la modulation de gènes de susceptibilité majeurs régulés par CREB.

BACKGROUND: Lapatinib is an effective anti-HER2 therapy in advanced breast cancer and docetaxel is one of the most active agents in breast cancer. Combining these agents in pre-treated patients with metastatic disease had previously proved challenging, so the primary objective of this study aimed to determine the maximum tolerated dose (MTD) in treatment-naive patients, by identifying acute dose-limiting toxicities (DLT) during cycle 1 in the first part of a phases 1-2 neoadjuvant European Organisation for Research and Treatment of Cancer (EORTC) trial. PATIENTS AND METHODS: Patients with large operable or locally-advanced HER2 positive breast cancer were treated with continuous lapatinib, and docetaxel every 21days for 4 cycles. Dose levels (DLs) were: 1000/75, 1250/75, 1000/85, 1250/85, 1000/100 and 1250/100 (mg/day)/(mg/m(2)). RESULTS: Twenty-one patients were included. Two DLTs occurred at dose level 5 (1000/100); one grade 4 neutropenia ⩾7days and one febrile neutropenia. A further 3 patients were therefore treated at the same dose with prophylactic granulocyte-colony stimulating factor (G-CSF), and 3 patients at dose level 6. No further DLTs were observed. CONCLUSIONS: Our recommended dose for phase II is lapatinib 1000mg/day and docetaxel 100mg/m(2) with G-CSF in HER2 positive non-metastatic breast cancer. The dose of lapatinib should have been 1250mg/day but we were mindful of the high rate of treatment discontinuation in GeparQuinto with lapatinib 1250mg/day combined with docetaxel. No grade 3-4 diarrhoea was observed. Pharmacodynamics analysis suggests that concomitant medications altering P-glycoprotein activity (in addition to lapatinib) can modify toxicity, including non-haematological toxicities. This needs verification in larger trials, where it may contribute to understanding the sources of variability in clinical toxicity and treatment discontinuation.

PURPOSE This double-blind, multicenter trial compared the efficacy and safety of a single daily oral dose of moxifloxacin with oral combination therapy in low-risk febrile neutropenic patients with cancer. PATIENTS AND METHODS Inclusion criteria were cancer, febrile neutropenia, low risk of complications as predicted by a Multinational Association for Supportive Care in Cancer (MASCC) score > 20, ability to swallow, and ≤ one single intravenous dose of empiric antibiotic therapy before study drug treatment initiation. Early discharge was encouraged when a set of predefined criteria was met. Patients received either moxifloxacin (400 mg once daily) monotherapy or oral ciprofloxacin (750 mg twice daily) plus amoxicillin/clavulanic acid (1,000 mg twice daily). The trial was designed to show equivalence of the two drug regimens in terms of therapy success, defined as defervescence and improvement in clinical status during study drug treatment (< 10% difference). Results Among the 333 patients evaluated in an intention-to-treat analysis, therapy success was observed in 80% of the patients administered moxifloxacin and in 82% of the patients administered combination therapy (95% CI for the difference, -10% to 8%, consistent with equivalence). Minor differences in tolerability, safety, and reasons for failure were observed. More than 50% of the patients in the two arms were discharged on protocol therapy, with 5% readmissions among those in either arm. Survival was similar (99%) in both arms. CONCLUSION Monotherapy with once daily oral moxifloxacin is efficacious and safe in low-risk febrile neutropenic patients identified with the help of the MASCC scoring system, discharged early, and observed as outpatients.

Background: Acute Myeloid Leukemia (AML) in the elderly is notoriously difficult to treat and has a low remission rate with very few long term survivors when using standard treatment approaches. Azacytidine, a hypomethylating agent, has been shown to induce remission and prolong survival in patients with myelodysplastic syndromes; studying this approach to patients with AML is therefore warranted. We present results of an ongoing phase II trial treating elderly or frail AML patients with Azacytidine. Methods: AML elderly or frail patients, and therefore unfit for an intensive chemotherapy regimens, with a WHO performance status 3 were considered for this trial. Trial therapy consisted of 100mg/m2 of Azacytidine injected subcutaneously on 5 consecutive days every 28 days up to 6 cycles, stopping at 6 months if no hematological improvement achieved, or earlier in the case of progression or complications. Treatment was continued beyond 6 months in responding patients. Trial therapy was considered uninteresting if the response rate (CR + PR) within 6 months of therapy initiation was 15% or less and promising if 34% or more. Using the exact single-stage phase II design by A'Hern with a 5% significance level and 90% power, 43 patients were required: If 10 or fewer achieved a response within 6 months the trial therapy should not be considered for further investigation in its current format for this indication and patient population. Results: Between September 2008 and January 2010, 45 evaluable patients across 10 Swiss centers were accrued with a median follow-up of 7 months (range: 0 - 13). 27 (60%) were male, median age was 74 (range: 55 - 86) years and 35 (78.8%) had performance status 0-1. Patients had been excluded from more intensive chemotherapy regimens because of age (n = 37) or due to comorbidities or patient refusal (n=8). Five patients had therapy related AML. Patients received a median of 3 (range: 1 - 10) cycles. Treatment was stopped for not achieving a response by the 6th cycle in 2 patients and earlier in 26 patients (for disease progression in 5, toxicity in 3, patient refusal in 2, recurrent infections in 1, and death in 8). Seventeen patients remain on therapy. The median time spent in the hospital was 12 days (1 - 30) in 24/38 patients hospitalized during the first treatment cycle and 13 days (2 - 28) in 15/31 patients hospitalized during subsequent cycles. Adverse events of grade III or higher most frequently reported were constitutional or hematologic, i.e. fatigue in 5, febrile neutropenia in 8, infections in 6, dyspnea in 6, anemia in 3, neutropenia in 12 and thrombocytopenia in 10, hemorrhage in 2 and retinal detachment in 5. Based on available data on 38 patients, CR/CRi or hematologic improvement or stable disease within 6 months of trial registration was observed in a proportion of patients. Final and mature data, determining whether the predefined proportion of responding patients has been reached or not, will be presented at the conference. Up to now there were a total of 26 deaths. Median overall survival time was 5.7 months (95% CI: 3.1, 8.7). Conclusions: The current results of this slightly modified Azacytidine schedule demonstrate a feasible new therapy option for elderly or frail AML patients in an outpatient setting with moderate, mainly hematologic toxicity.

Canadian healthcare is changing. Over the course of the past decade, the Health Care in Canada Survey (HCIC) has annually measured the reactions of the public and professional stakeholders to many of these change forces. In HCIC 2008, for the first time, the public's perception of their health status and all stakeholders' views of the burden and effective management of chronic diseases were sought. Overall, Canadians perceive themselves as healthy, with 84% of adults reporting good-to-excellent health. However, good health decreased with age as the occurrence of chronic illness rose, from 12% in the age group 18-24 to 65% for the population =65 years. More than 70% of all stakeholders were strongly or somewhat supportive of the implementation of coordinated care, or disease management programs, to improve the care of patients with chronic illnesses. Concordant support was also expressed for key disease management components, including coordinated interventions to improve home, community and self-care; increased wellness promotion; and increased use of clinical measurements and feedback to all stakeholders. However, there were also important areas of non-concordance. For example, the public and doctors consistently expressed less support than other stakeholders for the value of team care, including the use of non-physician professionals to provide patient care; increased patient involvement in decision-making; and the use of electronic health records to facilitate communication. The actual participation in disease management programs averaged 34% for professionals and 25% for the public. We conclude that chronic diseases are common, age-related and burdensome in Canada. Disease management or coordinated intervention often delivered by teams is also relatively common, despite its less-than-universal acceptance by all stakeholders. Further insights are needed, particularly into the variable perceptions of the value and efficacy of team-delivered healthcare and its important components.

The knowledge of the national legislation and the key concepts of bioethics are necessary for medical practice. The four principles of bioethics are autonomy, beneficence, non-maleficence, and justice. General internal medicine is the speciality of comprehensive care for often elderly patients with multiple chronic illnesses. This care is related to many ethically difficult decisions. In our article, we discuss common ethical problems in general internal medicine, including ethical aspects of the patient-physician relationship and medical decision making, the ethical significance of time management, research in bioethics and medical education.

OBJECTIVE: To identify pregnancy-related risk factors for different manifestations of congenital anorectal malformations (ARMs). DESIGN: A population-based case-control study. SETTING: Seventeen EUROCAT (European Surveillance of Congenital Anomalies) registries, 1980-2008. POPULATION: The study population consisted of 1417 cases with ARM, including 648 cases of isolated ARM, 601 cases of ARM with additional congenital anomalies, and 168 cases of ARM-VACTERL (vertebral, anal, cardiac, tracheo-esophageal, renal, and limb defects), along with 13 371 controls with recognised syndromes or chromosomal abnormalities. METHODS: Multiple logistic regression analyses were used to calculate adjusted odds ratios (ORs) for potential risk factors for ARM, such as fertility treatment, multiple pregnancy, primiparity, maternal illnesses during pregnancy, and pregnancy-related complications. MAIN OUTCOME MEASURES: Adjusted ORs for pregnancy-related risk factors for ARM. RESULTS: The ARM cases were more likely to be firstborn than the controls (OR 1.6, 95% CI 1.4-1.8). Fertility treatment and being one of twins or triplets seemed to increase the risk of ARM in cases with additional congenital anomalies or VACTERL (ORs ranging from 1.6 to 2.5). Maternal fever during pregnancy and pre-eclampsia were only associated with ARM when additional congenital anomalies were present (OR 3.9, 95% CI 1.3-11.6; OR 3.4, 95% CI 1.6-7.1, respectively), whereas maternal epilepsy during pregnancy resulted in a five-fold elevated risk of all manifestations of ARM (OR 5.1, 95% CI 1.7-15.6). CONCLUSIONS: This large European study identified maternal epilepsy, fertility treatment, multiple pregnancy, primiparity, pre-eclampsia, and maternal fever during pregnancy as potential risk factors primarily for complex manifestations of ARM with additional congenital anomalies and VACTERL.

Peroxisome proliferator-activated receptor (PPAR) dysfunction has been implicated in the manifestation of many diseases and illnesses, ranging from obesity to cancer. Herein, we discuss the role of PPARbeta, one of the three PPAR isotypes, during wound healing. While PPARbeta expression is undetectable in unchallenged and healthy adult interfollicular mouse skin, it is robustly re-activated in stress situations, such as upon phorbol ester treatment, hair plucking and cutaneous wounding. The inflammatory reaction associated with a skin injury activates the keratinocytes at the edges of the wound. This activation involves PPARbeta, whose expression and activity as transcription factor are up-regulated by pro-inflammatory signals. The re-activation of PPARbeta influences three important properties of the activated keratinocytes that are vital for rapid wound closure, namely, survival, migration and differentiation. The anti-apoptotic and, thus, survival role of PPARbeta is mediated by the up-regulation of expression of integrin-linked kinase and 3-phosphoinositide-dependent kinase-1. Both kinases are required for the full activation of the Akt1 survival cascade. Therefore, the up-regulation of PPARbeta, early after injury, appears to be important to maintain a sufficient number of viable keratinocytes at the wound edge. At a later stage of wound repair, the stimulation of keratinocyte migration and differentiation by PPARbeta is also likely to be important for the formation of a new epidermis at the wounded area. Consistent with these observations, the entire wound healing process is delayed in PPARbeta +/- mice and wound closure is retarded by 2-3 days. The multiple roles of PPARbeta in the complex keratinocyte response after injury and during skin repair certainly justify a further exploration of its potential as a target for wound healing drugs.

Background: Adverse drug reactions (ADRs) are a threat to patients' health and quality of life, and can generate significant expenses. They are generally underreported, with different rates in different health care systems. Methods: We conducted a 6-month survey of all primary admissions to the medical emergency department of a university hospital and assessed the rate, characteristics, avoidability, and marginal costs of ADRs. Results: A total of 7% of all admissions were mainly caused by ADRs. The most frequent were gastrointestinal bleeding (22.3%) and febrile neutropenia (14.4%). Anticancer drugs were involved in 22.7% of the cases, and anticoagulants, analgesics, and non-steroidal anti-inflammatory drugs in 8% each. Physicians had prescribed 70% of these drugs. Patients were predominantly treated in intermediate care units and ordinary wards. The mean cost per case amounted to CHF 3586+/-342, or a total of CHF 821204 over the 6-month-period (1 CHF=0.56 US$=0.87 Euro). A total of 67% were considered definitely imputable to drug effects and 32% were retrospectively regarded as avoidable. Conclusions: Interventions aimed at reducing the incidence of ADRs should be directed towards both patient education and physician training. This could save hospitals admissions and money, and could be used as an indicator of prescription quality.

Treatment of pediatric fever is based on two main molecules, paracetamol and ibuprofen. Fever should be treated when associated with discomfort. The two molecules have almost similar efficacy and safety. Monotherapy should be preferred to a combined or alternating treatment. Antipyretics do not seem to prevent febrile seizures.

BACKGROUND: Neoadjuvant trials conducted using a double HER2 blockade with lapatinib and trastuzumab, combined with different paclitaxel-containing chemotherapy regimens, have shown high pathological complete response (pCR) rates, but at the cost of important toxicity. We hypothesised that this toxicity might be due to a specific interaction between paclitaxel and lapatinib. This trial assesses the toxicity and activity of the combination of docetaxel with lapatinib and trastuzumab. PATIENTS AND METHODS: Patients with stage IIA to IIIC HER2-positive breast cancer received six cycles of chemotherapy (three cycles of docetaxel followed by three cycles of fluorouracil, epirubicin, cyclophosphamide). They were randomised 1 : 1 : 1 to receive during the first three cycles either lapatinib (1000 mg orally daily), trastuzumab (4 mg/kg loading dose followed by 2 mg/kg weekly), or trastuzumab + lapatinib at the same dose. The primary end point was pCR rate defined as ypT0/is. Secondary end points included safety and toxicity. pCR rate defined as ypT0/is ypN0 was assessed as an exploratory analysis. In June 2012, arm A was closed for futility based on the results from other studies. RESULTS: From October 2010 to January 2013, 128 patients were included in 14 centres. The percentage of the 122 assessable patients with pCR in the breast, and pCR in the breast and nodes, was numerically highest in the lapatinib + trastuzumab group (60% and 56%, respectively), intermediate in the trastuzumab group (52% and 52%), and lowest in the lapatinib group (46% and 36%). Frequency (%) of the most common grade 3-4 toxicities in the lapatinib /trastuzumab/lapatinib + trastuzumab arms were: febrile neutropenia 23/15/10, diarrhoea 9/2/18, infection (other) 9/4/8, and hepatic toxicity 0/2/8. CONCLUSIONS: This study demonstrates a numerically modest pCR rate increase with double anti-HER2 blockade plus chemotherapy, but suggests that the use of docetaxel rather than paclitaxel may not reduce toxicity.
