Dr Julius Spanier (1880-1959), pédiatre juif : acteur du développement de la pédiatrie sociale et préventive dans la première moitié du XXème siècle à Munich et victime des persécutions à l'égard des médecins juifs sous le IIIème Reich

Résumé Né à Munich en 1880, Julius Spanier obtient le titre de médecin en 1904. Après deux ans de spécialisation en pédiatrie, il ouvre son propre cabinet de médecin généraliste et spécialiste des maladies de l'enfance à Munich. Dès 1913, il participe à l'essor de la pédiatrie sociale et préventive de sa ville natale en assumant la direction de consultations de nourrissons. Ce travail - en partie interrompu par la Première Guerre mondiale à laquelle a participé le Dr Spanier comme médecin militaire - prend fin en 1933 lors de la prise de pouvoir nazie en raison des origines juives de notre médecin. Ces 30 années correspondent en Allemagne à un essor particulier de la pédiatrie sociale et préventive. Au début du XXème siècle apparaissent les premières consultations de nourrissons ; ainsi que de nombreuses associations de médecine sociale. La Première Guerre mondiale donne un élan décisif à la pédiatrie sociale, qui devient désormais une affaire d'Etat et dont le but est la diminution de la mortalité des nourrissons afin de remplacer les pertes humaines subies sur les champs de bataille. Après la fin de la guerre, les idées eugéniques de promouvoir une race aryenne pure prennent une place croissante dans la pédiatrie sociale. Une autre facette du développement de la pédiatrie sociale en Allemagne est l'institution, vers la fin du XIXème siècle, des premiers médecins scolaires. Le développement de la médecine scolaire est plus discret que celui de la médecine sociale des nourrissons, car suscitant moins d'intérêt de la part de l'Etat. Il s'imprègne aussi cependant des idées eugéniques de l'entre-deux-guerres. A Munich également, la médecine scolaire, fondée en 1907, ne connaît qu'un faible essor, jusqu'en 1933 qui sera le théâtre des réformes nazies. Le Dr Spanier devient en 1919 médecin scolaire en emploi accessoire, s'occupant de deux écoles de quartiers populaires munichois. Lors de la prise de pouvoir par Hitler, il est démis de ses fonctions comme médecin scolaire. Toute une législation dirigée contre les médecins juifs est mise en place, qui conduit en 1938 au retrait du droit d'exercer. Une minorité de médecins, nommés « Krankenbehandler », sont encore autorisés à soigner exclusivement les membres de la communauté juive. A Munich, capitale du mouvement nazi, 14 « Krankenbehandler » sont désignés, dont le Dr Spanier. Leur consultation se trouve dans l'unique hôpital juif de la ville, dont le nombre de lits est largement insuffisant face aux besoins rencontrés au sein de la communauté juive. En plus de son travail comme médecin-chef de l'hôpital juif, le Dr Spanier est médecin dans un camp de travail et un ghetto juifs de Munich. En 1942, lui, sa femme, les infirmières et tous les patients de la clinique sont déportés vers le camp de concentration de Theresienstadt, étape précédant dans la plupart des cas une déportation vers Auschwitz. De 1942 à 1945, le Dr Spanier exerce ses fonctions de médecin auprès des déportés du camp, avec le peu de moyens à disposition et dans un dévouement infatigable. Lui et sa femme échappent miraculeusement à la mort et reviennent à Munich en 1945. Le Dr Spanier assume alors diverses fonctions comme médecin et au sein de diverses organisations de dénazification et reconstruction d'une communauté juive munichoise. Il meurt en 1959.

A protocol guided by transpulmonary thermodilution and lactate levels for resuscitation of patients with severe burns.

Over-resuscitation is deleterious in many critically ill conditions, including major burns. For more than 15 years, several strategies to reduce fluid administration in burns during the initial resuscitation phase have been proposed, but no single or simple parameter has shown superiority. Fluid administration guided by invasive hemodynamic parameters usually resulted in over-resuscitation. As reported in the previous issue of Critical Care, Sánchez-Sánchez and colleagues analyzed the performance of a 'permissive hypovolemia' protocol guided by invasive hemodynamic parameters (PiCCO, Pulsion Medical Systems, Munich, Germany) and vital signs in a prospective cohort over a 3-year period. The authors' results confirm that resuscitation can be achieved with below-normal levels of preload but at the price of a fluid administration greater than predicted by the Parkland formula (2 to 4 mL/kg per% burn). The classic approach based on an adapted Parkland equation may still be the simplest until further studies identify the optimal bundle of resuscitation goals.

Correlation of wear in vivo and six laboratory wear methods.

OBJECTIVE: We examined the correlation between clinical wear rates of restorative materials and enamel (TRAC Research Foundation, Provo, USA) and the results of six laboratory test methods (ACTA, Alabama (generalized, localized), Ivoclar (vertical, volumetric), Munich, OHSU (abrasion, attrition), Zurich). METHODS: Individual clinical wear data were available from clinical trials that were conducted by TRAC Research Foundation (formerly CRA) together with general practitioners. For each of the n=28 materials (21 composite resins for intra-coronal restorations [20 direct and 1 indirect], 5 resin materials for crowns, 1 amalgam, enamel) a minimum of 30 restorations had been placed in posterior teeth, mainly molars. The recall intervals were up to 5 years with the majority of materials (n=27) being monitored, however, only for up to 2 years. For the laboratory data, the databases MEDLINE and IADR abstracts were searched for wear data on materials which were also clinically tested by TRAC Research Foundation. Only those data for which the same test parameters (e.g. number of cycles, loading force, type of antagonist) had been published were included in the study. A different quantity of data was available for each laboratory method: Ivoclar (n=22), Zurich (n=20), Alabama (n=17), OHSU and ACTA (n=12), Munich (n=7). The clinical results were summed up in an index and a linear mixed model was fitted to the log wear measurements including the following factors: material, time (0.5, 1, 2 and 3 years), tooth (premolar/molar) and gender (male/female) as fixed effects, and patient as random effect. Relative ranks were created for each material and method; the same was performed with the clinical results. RESULTS: The mean age of the subjects was 40 (±12) years. The materials had been mostly applied in molars (81%) and 95% of the intracoronal restorations were Class II restorations. The mean number of individual wear data per material was 25 (range 14-42). The mean coefficient of variation of clinical wear data was 53%. The only significant correlation was reached by OHSU (abrasion) with a Spearman r of 0.86 (p=0.001). Zurich, ACTA, Alabama generalized wear and Ivoclar (volume) had correlation coefficients between 0.3 and 0.4. For Zurich, Alabama generalized wear and Munich, the correlation coefficient improved if only composites for direct use were taken into consideration. The combination of different laboratory methods did not significantly improve the correlation. SIGNIFICANCE: The clinical wear of composite resins is mainly dependent on differences between patients and less on the differences between materials. Laboratory methods to test conventional resins for wear are therefore less important, especially since most of them do not reflect the clinical wear.

Specialized pediatric palliative home care: a prospective evaluation.

Abstract Objectives: In Germany since 2007 children with advanced life-limiting diseases are eligible for Pediatric Palliative Home Care (PPHC), which is provided by newly established specialized PPHC teams. The objective of this study was to evaluate the acceptance and effectiveness of PPHC as perceived by the parents. Methods: Parents of children treated by the PPHC team based at the Munich University Hospital were eligible for this prospective nonrandomized study. The main topics of the two surveys (before and after involvement of the PPHC team) were the assessment of symptom control and quality of life (QoL) in children; and the parents' satisfaction with care, burden of patient care (Häusliche Pflegeskala, home care scale, HPS), anxiety and depression (Hospital Anxiety and Depression Scale, HADS), and QoL (Quality of Life in Life-Threatening Illness-Family Carer Version, QOLLTI-F). Results: Of 43 families newly admitted to PPHC between April 2011 and June 2012, 40 were included in the study. The median interval between the first and second interview was 8.0 weeks. The involvement of the PPHC team led to a significant improvement of children's symptoms and QoL (P<0.001) as perceived by the parents; and the parents' own QoL and burden relief significantly increased (QOLLTI-F, P<0.001; 7-point change on a 10-point scale), while their psychological distress and burden significantly decreased (HADS, P<0.001; HPS, P<0.001). Conclusions: The involvement of specialized PPHC appears to lead to a substantial improvement in QoL of children and their parents, as experienced by the parents, and to lower the burden of home care for the parents of severely ill children.

Redox dysregulation and oxidative stress in schizophrenia: genetic and functional anomalies of glutathione synthesis in patients and experimental models involving GABA interneurons and NMDA receptors

Objective: Converging evidence speak in favor of an abnormal susceptibility to oxidative stress in schizophrenia. A decreased level of glutathione (GSH), the principal non-protein antioxidant and redox regulator, was observed both in cerebrospinal-fluid and prefrontal cortex of schizophrenia patients (Do et al., 2000). Results: Schizophrenia patients have an abnormal GSH synthesis most likely of genetic origin: Two independent case-control studies showed a significant association between schizophrenia and a GAG trinucleotide repeat (TNR) polymorphism in the GSH key synthesizing enzyme glutamate-cysteine-ligase (GCL) catalytic subunit (GCLC) gene. The most common TNR genotype 7/7 was more frequent in controls, whereas the rarest TNR genotype 8/8 was three times more frequent in patients. The disease-associated genotypes correlated with a decrease in GCLC protein expression, GCL activity and GSH content. Such a redox dysregulation during development could underlie the structural and functional anomalies in connectivity: In experimental models, GSH deficit induced anomalies similar to those observed in patients. (a) morphology: In animal models with GSH deficit during the development we observed in prefrontal cortex a decreased dendritic spines density in pyramidal cells and an abnormal development of parvalbumine (but not of calretinine) immunoreactive GABA interneurones in anterior cingulate cortex. (b) physiology: GSH depletion in hippocampal slices induces NMDA receptors hypofunction and an impairment of long term potentiation. In addition, GSH deficit affected the modulation of dopamine on NMDA-induced Ca 2+ response in cultured cortical neurons. While dopamine enhanced NMDA responses in control neurons, it depressed NMDA responses in GSH-depleted neurons. Antagonist of D2-, but not D1-receptors, prevented this depression, a mechanism contributing to the efficacy of antipsychotics. The redox sensitive ryanodine receptors and L-type calcium channels underlie these observations. (c) cognition: Developing rats with low [GSH] and high dopamine lead deficit in olfactory integration and in object recognition which appears earlier in males that females, in analogy to the delay of the psychosis onset between man and woman. Conclusion: These clinical and experimental evidence, combined with the favorable outcome of a clinical trial with N-Acetyl Cysteine, a GSH precursor, on both the negative symptoms (Berk et al., submitted) and the mismatch negativity in an auditory oddball paradigm supported the proposal that a GSH synthesis impairment of genetic origin represent, among other factors, one major risk factor in schizophrenia.

Investigating the genetic variation underlying episodicity in major depressive disorder: Suggestive evidence for a bipolar contribution.

BACKGROUND: Highly recurrent major depressive disorder (MDD) has reportedly increased risk of shifting to bipolar disorder; high recurrence frequency has, therefore, featured as evidence of 'soft bipolarity'. We aimed to investigate the genetic underpinnings of total depressive episode count in recurrent MDD. METHODS: Our primary sample included 1966 MDD cases with negative family history of bipolar disorder from the RADIANT studies. Total episode count was adjusted for gender, age, MDD duration, study and center before being tested for association with genotype in two separate genome-wide analyses (GWAS), in the full set and in a subset of 1364 cases with positive family history of MDD (FH+). We also calculated polygenic scores from the Psychiatric Genomics Consortium MDD and bipolar disorder studies. RESULTS: Episodicity (especially intermediate episode counts) was an independent index of MDD familial aggregation, replicating previous reports. The GWAS produced no genome-wide significant findings. The strongest signals were detected in the full set at MAGI1 (p=5.1×10(-7)), previously associated with bipolar disorder, and in the FH+ subset at STIM1 (p=3.9×10(-6) after imputation), a calcium channel signaling gene. However, these findings failed to replicate in an independent Munich cohort. In the full set polygenic profile analyses, MDD polygenes predicted episodicity better than bipolar polygenes; however, in the FH+ subset, both polygenic scores performed similarly. LIMITATIONS: Episode count was self-reported and, therefore, subject to recall bias. CONCLUSIONS: Our findings lend preliminary support to the hypothesis that highly recurrent MDD with FH+ is part of a 'soft bipolar spectrum' but await replication in larger cohorts.

Genetic relationships between suicide attempts, suicidal ideation and major psychiatric disorders: A genome-wide association and polygenic scoring study.

Epidemiological studies have recognized a genetic diathesis for suicidal behavior, which is independent of other psychiatric disorders. Genome-wide association studies (GWAS) on suicide attempt (SA) and ideation have failed to identify specific genetic variants. Here, we conduct further GWAS and for the first time, use polygenic score analysis in cohorts of patients with mood disorders, to test for common genetic variants for mood disorders and suicide phenotypes. Genome-wide studies for SA were conducted in the RADIANT and GSK-Munich recurrent depression samples and London Bipolar Affective Disorder Case-Control Study (BACCs) then meta-analysis was performed. A GWAS on suicidal ideation during antidepressant treatment had previously been conducted in the Genome Based Therapeutic Drugs for Depression (GENDEP) study. We derived polygenic scores from each sample and tested their ability to predict SA in the mood disorder cohorts or ideation status in the GENDEP study. Polygenic scores for major depressive disorder, bipolar disorder and schizophrenia from the Psychiatric Genomics Consortium were used to investigate pleiotropy between psychiatric disorders and suicide phenotypes. No significant evidence for association was detected at any SNP in GWAS or meta-analysis. Polygenic scores for major depressive disorder significantly predicted suicidal ideation in the GENDEP pharmacogenetics study and also predicted SA in a combined validation dataset. Polygenic scores for SA showed no predictive ability for suicidal ideation. Polygenic score analysis suggests pleiotropy between psychiatric disorders and suicidal ideation whereas the tendency to act on such thoughts may have a partially independent genetic diathesis. © 2014 Wiley Periodicals, Inc.
