Intérêt du bleu de méthylène dans la chirurgie de l'hyperparathyroïdism primaire [Methylene blue in surgery of primary hyperparathyroidism]

Is surgery for primary hyperparathyroidism easier when methylene blue (MB) is given preoperatively? This retrospective study compares the durations of interventions for primary hyperparathyroidism carried out after i.v. MB administration to those when no MB was given. Over a period of 20 years (June 1976 to December 1996), 175 consecutive patients (56 men and 119 women, with ages ranging from 16 to 92, mean 59.6) were operated upon for primary hyperparathyrodism; 55 were operated before February 1986--the period when BM was introduced routinely, and 120 after. Thirty-two other patients were excluded from the study: 14 had had a previous cervicotomy and 18 another procedure in addition to the parathyroidectomy (usually on the thyroid gland), two conditions which prolonged the time devoted to parathyroid identification and excision. Preoperative calcemia averaged 2.97 mmol/L (2.34 to 4.59) and mean preoperative PTH was equal to 2.6 times the upper normal limit (0.5 to 24.1). Both groups were similar for as age, sex, preoperative calcium and PTH, and histologies. Methylene blue was administered intravenously (5 mg/kg diluted in 500 cc of 5% glucose) over a period of time of one hour starting two hours prior to surgery. All 175 procedures were performed by two surgeons and duration of surgery was recorded from the anesthesiologist's notes. There were 149 adenomas (85%), 24 hyperplasias (14%), a combination of both in two, and unspecified in two others. Except for a case of acute lower back pain synchronous to the injection of the dye (which was immediately stopped), MB was well tolerated. Mean duration for the 55 interventions performed without MB was 68 minutes (35 to 140, median 60), compared to 49 minutes for the 120 procedures carried out after MB had been given (20 to 155, median 45). Differences in operative, times were highly significant (p < 10(-6) and represented a gain of time of 27%. Surgery for primary hyperparathyroidism was significantly shorter when it was preceded by the administration of MB, a dye which facilitates the identification of pathologic parathyroid gland(s).

HypnoLaus: le sommeil sous la loupe [HypnoLaus sleep cohort study].

Normal sleep patterns and prevalence of sleep disorders in the general population are largely unknown. The aim of HypnoLaus cohort study is to record sleep and analyze sleep characteristics in a large population-based sample, which had undergone comprehensive genetic, somatic, and psychiatric investigations. Full polysomnography has already been performed in more than 1100 middle aged men and women randomly selected from Lausanne general population (goal 2000-3000 sleep recordings). Over 4000 additional subjects from the same population have filled various questionnaires on their sleep habits and complaints. These results combined with genetic, cardiovascular, metabolic, and psychiatric data provide a unique opportunity to determine the interaction between sleep, its genetic determinants and cardiovascular, psychiatric, or metabolic diseases.

Les adénocarcinomes kystiques de la glande lacrymale [Cystic adenocarcinomas of the lacrymal gland]

Adenoid cystic carcinoma of the lacrimal gland. BACKGROUND: Adenoid cystic carcinoma is the most frequent epithelial tumour of the lacrimal gland. It represents 1.6 % of the orbital tumours. The aim of this study is to present a series of such patients who were followed up in our clinic and to discuss their clinical management in order to achieve a better life prognosis. MATERIALS AND METHODS: The cases we followed up in our department were presented, the treatment modalities were discussed, and conclusions were drawn. RESULTS: Six patients with this pathology were examined, 3 men and 3 women, aged 31 to 69 years. A large excision was performed in 5 patients (exenteration alone or extended exenteration with complementary radiotherapy) and in 1 patient with excision of the tumour followed by radiotherapy. One patient died due to carcinoma six years after the first surgery. The median follow-up period of our cases is 25 months. CONCLUSION: Adenoid cystic carcinoma of the lacrimal gland is a malignant tumour with a reserved prognosis. Various treatments were proposed to improve the mortality rate of the disease. At present radical surgery with or without complementary therapy seems to give the best chances of healing, at least with short or mid-term follow-up.

Study of the mechanisms regulating the proliferative potential of human CD8+T lymphocytes over-expressing telomerase reverse transcriptase (hTERT)

Résumé La plupart des cellules issues du sang ont une durée de vie limitée. Dans les cellules somatiques humaines, y incluant les lymphocytes T, la taille des télomères diminue progressivement à chaque division cellulaire, pouvant aboutir à des instabilités chromosomiques. L'expression ectopique du gène de la transcriptase réverse de la télomérase (hTERT) dans les cellules restaure l'activité de la télomérase, et permet un rallongement de leur vie réplicative. Malgré l'absence de signes caractéristiques de transformation, nous ne savons pas encore si les cellules somatiques qui surexpriment hTERT sont physiologiquement indiscernables des cellules normales. Certaines études récentes proposent que la télomérase joue plusieurs rôles additionnels dans d'autres phénomènes biologiques tels que la réparation de l'ADN, la survie et la croissance des cellules. Dans notre étude, nous avons utilisé des clones issus de lymphocytes T cytotoxiques surexprimant la télomérase afin d'étudier les mécanismes moléculaires qui règlent leur prolifération et leur sénescence. Nous avons montré que les «jeunes » cellules T exprimant ou non hTERT révèlent des taux de croissance identiques suite à des réponses de stimulation induites par des mitogènes. De plus, aucun changement global dans leur expression des gènes n'a pu être mis en évidence. Curieusement, nous avons observé des réponses réduites dans la prolifération des cellules transduites avec la télomérase qui présentaient une élongation des télomères et une durée de vie prolongée. Ces cellules, malgré le maintien d'un niveau élevé de l'expression de gènes impliqués dans la progression du cycle cellulaire, ont également montré une expression accrue de plusieurs gènes trouvés en commun avec nos lymphocytes T vieillissants n'exprimant pas de télomérase. En particulier, les cellules ayant une durée de vie prolongée grâce à l'expression de la télomérase accumulaient également certains inhibiteurs du cycle cellulaire tels que p16Ink4a et p21Cip1, associés à l'arrêt de la croissance cellulaire. En résumé, nos résultats indiquent la présence fonctionnelle de mécanismes alternatifs pouvant contrôler la croissance réplicative de ces cellules; ils sont donc encourageants dans l'optique d'une utilisation à moindre risque de lymphocytes T «immortalisés » à des fins thérapeutiques pour traiter les tumeurs malignes ou les infections. Summary Most mature blood cells have a finite life span. In human somatic cells, including T lymphocytes, telomeres progressively shorten with each cell division eventually leading to chromosomal instability. Ectopic expression of the human telomerase reverse transcriptase (hTERT) gene in cells restores telomerase activity and results in the extension of their replicative life span. Despite lack of transformation characteristics, it is yet unknown whether somatic cells that over-express telomerase are biologically and physiologically indistinguishable from normal cells. Recent data suggest that telomerase might mediate additional functions in DNA repair, cell survival and cell growth. Using CD8+ T lymphocyte clones over-expressing telomerase we investigated the molecular mechanisms that regulate T cell proliferation and senescence. Here we show that early-passage T cell clones transduced or not with hTERT displayed identical growth rates upon mitogenic stimulation and no marked global changes in gene expression. Surprisingly, reduced proliferative responses were observed in hTERT-transduced cells with elongated telomeres and extended life span. These cells, despite maintaining high expression level of genes involved in cell cycle division and progression, also showed increased expression of several genes associated with normal aging T lymphocytes. In particular, late passage T cells over-expressing telomerase accumulated the cyclin-dependent inhibitors p16INK4a and p21CIP1 that have largely been associated with in vitro growth arrest. Whether tumor-reactive CD8+ T cells that ectopically express telomerase could now be used for adoptive transfer therapy in cancer patients remains unclear at this point. Nevertheless, our results regarding the safe and effective use of hTERT-transduced lymphocytes are encouraging, since they indicate that alternative growth arrest mechanisms such as p 16 and p21 are still functional in these cells and regulate to some extend their growth potential.

Exposition de l'enfant a des violences domestiques. Un modèle pluridisciplinaire de détection, d'evaluation et de prise en charge [Children's exposure to domestic violence. A multidisciplinary model of detection, assessment and management].

Children psychological abuse is difficult to identify. However, its consequences on child development can be as serious as physical and sexual abuses. It is therefore essential, to implement in our hospitals, structures whose missions are successively to detect victims, evaluate them on somatic and psychological levels, and elaborate a therapy. We propose a model for the achievement of these objectives through collaboration between the Medical Unit of Violence, the Pediatric CAN Team and the Unit of Les Boréales.

Homéostasie, marqueurs somatiques et intentionnalité : le statut de la représentation et ses implications en psychanalyse et en neuroscience

Résumé : Si la psychanalyse est régulièrement remise en cause pour son manque de fondement scientifique, de nombreux travaux issus des neurosciences en appellent paradoxalement à un retour aux thèses freudiennes. Cette étude se propose, dans ce contexte, de revisiter les bases neurobiologiques de la métapsychologie et de montrer comment celle-ci repose sur une conception homéostatique du vivant. On en tire plusieurs conséquences. Premièrement, contre Brentano, selon qui l'intentionnalité est la marque du psychologique, on propose que celle-ci s'avère être, plus originellement, la marque des régulations biologiques. Deuxièmement, on montre comment Freud et Damasio développent des conceptions similaires sur le fonctionnement homéostatique de la cognition. Sur le plan épistémologique, on plaide en faveur de la complémentarité de ces deux approches. Si Damasio met au jour les variables somatiques permettant de mesurer les effets de la vie psychique, la théorie pulsionnelle permet de dépasser les problèmes liés à l'ambiguïté de la notion de «représentation cérébrale ». C'est à partir de cette thèse que l'on peut, selon nous, appréhender la psychanalyse comme un double projet visant à articuler une naturalisation de l'appareil psychique à une herméneutique de ses productions. On considère cette double visée comme une réponse à la difficulté centrale que rencontrent les sciences de l'esprit quant aux conditions de possibilité d'une naturalisation de l'intentionnalité. A partir de cette problématique, il devient pertinent d'évaluer la solution freudienne à la lumière de la posture intentionnelle dennettienne et de la théorie gazzaniguienne de l'interpreter. II ne s'agit pas, selon ces dernières approches, de naturaliser directement l'intentionnalité, au risque de commettre une erreur de catégorie. Il est question, au contraire, d'utiliser les principes du fonctionnement homéostatique comme autant de «règles »interprétatives permettant, sur le plan psychologique, de construire du sens. On trouve enfin dans le modèle de l'espace global de travail un moyen de remettre au goût du jour la conception freudienne, dynamique et conflictuelle, du fonctionnement psychique. On avance enfin, à partir de ce modèle, des hypothèses sur les mécanismes cérébraux susceptibles de sous-tendre l'efficacité thérapeutique de la cure analytique. Abstract : While Psychoanalysis' scientific basis is open to question, some neuroscience works are paradoxically calling for a return to Freud. Therefore, the first aim of our study consists in revisiting metapychology's neurobiological roots and to show how it is grounded on a homeostatic theory of life. Several consequences can be drawn from this statement. Firstly, in opposition to Brentanian definition of intentionality, as the specific mark of psychology, we argue that it is more specifically the mark of biological balance. Secondly, this statement allows to show how Freud's and Damasio's theories share common views on the homeostatic functioning of cognition. From an epistemological point of view, they complete one another. If Damasio has highlighted the measurable somatic variables from which we can infer psychic life, the theory of drives allows conceptual difficulties linked to the use of the ambiguous notion of "cerebral representation" to be overcome. According to us, this thesis leads psychoanalysis to be approached as a twin project aiming to articulate psyche naturalization, to a hermeneutic of its productions. It maybe seen as a way to respond to the central issue of mind sciences, that is, to account for the naturalization of intentionality. Given this theoretical framework, it seems relevant to reconsider freudism in the light of the dennettian intentional stance and the gazzanigan theory of interpreter. Then, freudism can be seen as a way to avoid a category mistake. Its solution rejects direct intentionality naturalization in favor of a construction of sense. In this framework, interpretation is regulated by the rules abstracted from the homeostatic functioning of life. Furthermore, we show how the dynamic and conflictual Freudian psyche can be evaluated using the Global workspace model, which allows us to put forth hypotheses on the cerebral mechanisms that may underlie the efficiency of analytical cure.

Evidence of altered antioxidant systems and signs of elevated oxidative stress are reported in peripheral tissue and brain of schizophrenic patients, including low levels of glutathione (GSH), a major thiol antioxidant and redox buffer. Functional and genetic data indicate that an impaired regulation of GSH synthesis is a vulnerability factor for the disease. Impaired GSH synthesis from a genetic origin combined with environmental risk factors generating oxidative stress (e.g., malnutrition, exposure to toxins, maternai infection and diabetes, obstetrical complications, and psychological stress) could lead to redox dysregulation. This could subsequently perturb normal brain development and maturation with delayed functional consequences emerging in early adulthood. Depending on the nature and the time of occurrence of the environmental insults, the structural and functional delayed consequences could vary, giving rise to various endophenotypes. The use of animal models of GSH deficit represents a valuable approach to investigate how interactions between genetic and environmental factors lead to the emergence of pathologies found in the disease. Moreover, these models of GSH can be useful to investigate links between schizophrenia and comorbid somatic disorders, as dysregulation of the GSH system and elevated oxidative stress are also found in cardiovascular diseases and diabetes. This chapter reviews pharmacological and genetic rodent models of GSH synthesis dysregulation used to address some of the aforementioned issues. Up to date, these models revealed that GSH deficits lead to morphological, physiological, and behavioral alterations that are quite analogous to pathologies observed in patients. This includes hypofunction of NMDA receptors, alteration of dopamine neurotransmission, anomalies in parvalbumin-immunoreactive fast-spiking interneurons, and reduced myelination. In addition, a GSH deficit affects the brain in a region-specific manner, the anterior cingulate cortex and the ventral hippocampus being the most vulnerable regions investigated. Interestingly, a GSH deficit during a limited period of postnatal development is sufficient to have long-lasting consequences on the integrity of PV-IR interneurons in the anterior cingulate cortex and impairs cognitive functions in adulthood. Finally, these animal models of GSH deficit display behavioral impairments that could be related to schizophrenia. Altogether, current data strongly support a contributing role of a redox dysregulation on the development of pathologies associated with the illness and demonstrate the usefulness of these models to better understand the biological mechanisms leading to schizophrenia.

L'apathie, un symptôme transnosographique: diagnostic différentiel et prise en charge [Apathy, a transnosographic symptom: diagnosis and treatment]

Apathy defined as a loss of motivation and interest for novelty is a frequent symptom encountered in a number of psychiatric and somatic disorders. The purpose of this article is to provide an overview of the many different medical contexts where apathy may occur and help clinicians to differentiate it from a depressive syndrome. The treatment of apathy requires a diagnostic clarification in order to treat the underlying condition. Then, pharmacological or non-pharmacological interventions may help to specifically improve apathy.

Lipid reserves of red mullet (Mullus barbatus) during pre-spawning in the northwestern Mediterranean

Lipid reserves are a particularly important attribute of fishes because they have a large influence on growth, reproduction and survival. This study analyses the lipid content of red mullet (Mullus barbatus) pre-spawners in three different areas of the northwestern Mediterranean in relation to trawling activities and river runoff. The muscle lipid was considered as an indicator of the somatic condition of individuals whilst the gonad lipid was used as a proxy of the energy invested in reproduction. The results show that fish with the highest muscle lipid levels inhabited the area where fishing impact was lowest. Since the abundance and biomass of polychaetes, which represent the main food source for red mullet, were found to be lower in trawled zones than in unfished ones, we suggest that differences in the muscle lipid levels between areas might be attributed to variation in prey abundance in relation to fishing impact. However, no impact of river runoff on lipid reserves of red mullet was observed. The results also show that muscle and gonad lipid reserves are not related to each other during pre-spawning

Clinicopathologic and molecular analysis of a choroidal pigmented schwannoma in the context of a PTEN hamartoma tumor syndrome.

PURPOSE: To report the first case of choroidal schwannoma in a patient affected by PTEN hamartoma tumor syndrome (PHTS) and investigate the molecular involvement of the phosphatase and tensin homolog (PTEN) and neurofibromin 2 (NF2) genes in this rare intraocular tumor. DESIGN: Observational case report. PARTICIPANT: A 10-year-old girl diagnosed with PHTS. METHODS: The enucleated specimen underwent histologic, immunohistochemical, and transmission electronic microscopy. The expression of PTEN and NF2 and their protein products were evaluated by reverse transcription-polymerase chain reaction and immunohistochemistry. Somatic mutations of PTEN and NF2, as well as allelic loss, were investigated by direct sequencing of DNA extracted from the tumor. PTEN epigenetic silencing was investigated by pyrosequencing. MAIN OUTCOME MEASURES: Histopathologic and molecular characterization of a choroidal pigmented schwannoma. RESULTS: Histopathologic, immunohistochemical, and electron microscopic analysis demonstrated features consistent with a pigmented cellular schwannoma of the choroid. We found no loss of heterozygosity at the genomic level for the PTEN germline mutation and no promoter hypermethylation or other somatic intragenic mutations. However, we observed an approximate 40% reduction of PTEN expression at both the mRNA and the protein level, indicating that the tumor was nonetheless functionally deficient for PTEN. Although DNA sequencing of NF2 failed to identify any pathologic variants, its expression was abolished within the tumor. CONCLUSIONS: We report the first description of a pigmented choroidal schwannoma in the context of a PHTS. This rare tumor showed a unique combination of reduction of PTEN and absence of NF2 expression.

Long-term outcome of primary endoresection of choroidal melanoma.

BACKGROUND: Endoresection of choroidal melanoma may offer the best hope of conserving vision in some patients but is controversial because of concerns regarding iatrogenic tumour dissemination. METHODS: Retrospective, non-randomised study of consecutive patients who underwent endoresection for choroidal melanoma at the Liverpool Ocular Oncology Centre between 1996 and 2010. RESULTS: The study included 71 patients with a mean age of 58.7 years. The tumour extended within 2 disc diameters of the optic disc in 46 (65%) eyes, involving the disc in 24 (34%) eyes. The mean largest basal tumour diameter and tumour thickness were 9.5 mm and 4.4 mm, respectively. The median follow-up was 4.1 years. The visual acuity at the latest follow-up was better than 6/30 in 31% eyes. The main causes of visual loss were foveal excision, rhegmatogenous retinal detachment (RD) and proliferative vitreo-retinopathy (PVR). Local recurrence developed in two patients (3%), who were treated by enucleation and proton beam radiotherapy, respectively. RD occurred in 16 cases (22%). Three (4%) eyes were enucleated, two because of PVR and one because of local tumour recurrence. Five patients died of metastatic disease. CONCLUSIONS: Endoresection achieved high rates of local tumour control. This operation would seem to be a useful alternative to radiotherapy as a means of conserving vision in eyes with juxtapapillary melanoma.

Associations between psychiatric disorders and cardiovascular risk factors

Bien que de nombreuses études suggèrent des liens entre les troubles psychiatriques et les maladies cardiovasculaires (MCV), peu ont utilisé des investigations somatique, biologique et psychiatrique adéquates. Pour déterminer les potentiels mécanismes impliqués dans ces associations, plusieurs études ont investigué le lien entre les troubles psychiatriques et les facteurs de risque des maladies cardiovasculaires (FRCV) (surpoids, diabète, dyslipidémie, hypertension artérielle, inactivité, consommation de cigarettes). De plus, des biomarqueurs (régulateurs du métabolisme, marqueurs hépatiques et inflammatoires) pouvant être associés à la fois aux troubles psychiatriques et aux FRCV ont été étudiés mais avec des résultats contradictoires. Basée sur un large échantillon de la population générale de la Ville de Lausanne et des investigations somatique et psychiatrique adéquates, cette thèse comporte deux articles: le premier étudie l'association entre les troubles psychiatriques majeurs et les FRCV; le second établit les liens entre certains biomarqueurs et le développement du diabète de type 2. Appliquant une méthodologie rigoureuse sur un échantillon de 3716 sujets de la population lausannoise âgés de 35 à 66 ans, les résultats du premier article ont montré que 1) le sous-type atypique de la dépression était associé à une augmentation du risque de souffrir de plusieurs FRCV (surpoids, diabète et syndrome métabolique), contrairement à d'autres sous-types de dépression, 2) les problèmes d'alcool étaient associés à un risque accru de souffrir de diabète et de dyslipidémie, 3) presque tous les troubles psychiatriques étaient associés à une consommation régulière de cigarettes. Quant au deuxième article, parmi les différents biomarqueurs testés, seul un niveau bas d'adiponectine (une hormone produite par le tissu adipeux qui affecte la sensibilité à l'insuline) était associé à un risque accru de souffrir de diabète par la suite. Ces résultats soulignent la nécessité pour les spécialistes de distinguer les sous-types de dépression pour le risque cardiovasculaire et de donner une attention particulière au sous-type atypique. Un problème d'alcool comorbide pourrait accroître le risque cardiovasculaire. De plus, des efforts pour diminuer la cigarette chez les sujets souffrant de troubles psychiatriques seraient une mesure préventive importante contre le développement des MCV. Le rôle de l'adiponectine dans l'association entre les troubles psychiatriques et les FRCV restant incertain, une prochaine analyse devrait déterminer le lien entre ce biomarqueur et la dépression atypique. - Despite the fact that several studies have highlighted associations between psychiatric disorders and cardiovascular diseases (CVD), few have used adequate somatic, biological and psychiatric measures. To determine potential mechanisms implicated in these associations, several studies have assessed the relationship between psychiatric disorders and cardiovascular risk factors (CVRFs), such as overweight, diabetes, dyslipidemia, hypertension, physical inactivity and smoking. Moreover, biomarkers such as metabolic regulators, hepatic and inflammatory markers, which could be associated with both psychiatric disorders and CVRFs, have been studied yielding contradictory results. Based on a population-based sample from the city of Lausanne and using adequate somatic and psychiatric investigations, this dissertation encompasses two articles: the first studies the associations between major psychiatric disorders established for lifetime and CVRFs; the second studies the associations between certain biomarkers and the development of type 2 diabetes. Using standardized contemporary methodology in a sample composed of 3716 individuals aged from 35 to 66 years, the first article revealed associations between 1) the atypical depression subtype and an increased risk of several CVRFs (overweight, diabetes and the metabolic syndrome) in contrast to other depression subtypes; 2) alcohol disorders and an increased risk of diabetes and dyslipidemia; 3) almost all psychiatric disorders and a lifetime history of regular cigarette smoking. The second article showed, among the various biomarkers tested, that only lower levels of adiponectin (a hormone produced by adiposity which affects sensitivity to insulin) were associated with an increased risk of subsequent type 2 diabetes. Our results highlight the need for specialists to subtype depression when studying the cardiovascular risk and to pay particular attention to the atypical subtype. A comorbid alcohol misuse may further increase the cardiovascular risk. Moreover, efforts to diminish smoking in subjects suffering from psychiatric disorders could be an important tool for preventing subsequent CVD. The role of adiponectin in the association between psychiatric disorders and CVRFs should still be elucidated, and future analyses should focus in particular on the relationship between this biomarker and atypical depression.

Mutilations génitales féminines: l'adolescente en quête de réponses [Female genital mutilation: need for answers at the age of adolescence]

En Suisse, le nombre de filles et de femmes migrantes excisées au cours de leur enfance dans leur pays d'origine ou menacées de mutilations génitales rituelles est estimé à 6-7000. Les professionnels de la santé en tant qu'interlocuteurs privilégiés doivent donc être en mesure de répondre aux questions y relatives, non seulement durant l'adolescence, mais aussi dans toutes les phases de la vie. L'absence d'information ou de transmission par des aînées aussi bien avant l'excision qu'au moment de la maturité sexuelle en fait souvent un événement biographique traumatisant. Arrivées en Suisse, le décalage entre les attentes socioculturelles et familiales et le vécu individuel, influencé par le pays d'accueil, peut s'avérer particulièrement difficile à vivre pour les jeunes filles concernées. In Switzerland, the estimated number of survivors after traditional female genital mutilation in the country of origin or girls and adult women at risk is 6-7000. Health professionals must be able to respond adequately to their questions not only during adolescence but through out the different periods of life. The lack of information or transmission by the seniors as well before the excision as at the time of sexual maturity contributes in a large measure to the frequent biographic trauma. It can be very difficult for the girls to deal with the gap between socio cultural and family expectations and their individual life experience in Switzerland.
