Critical evaluation of outcome scales assessment of lateral ankle ligament reconstruction

Introduction: Les résultats d'une chirurgie du pied et de la cheville peuvent être évalués par des scores spécifiques à la région anatomique ainsi que par des scores spécifiques à la pathologie. Beaucoup de scores existent rendant la comparaison entre les études difficile. La présente étude se focalise sur une pathologie fréquente du pied et de la cheville et compare les résultats obtenu par deux scores spécifiques à la région et deux scores spécifiques à la pathologie. Méthode: Nous avons revu 41 patients ayant bénéficié d'une plastie ligamentaire externe de la cheville. Quatre scores ont été administrés simultanément: the Cumberland Ankle Instability Tool (CAIT) et the Chronic Ankle Instability Scale (CAIS), spécifiques à la pathologie, the American Orthopedic Foot & Ankle Society (AOFAS) hindfoot scale et the Foot and Ankle Ability Measure comprenant deux parties (FAAM1 et FAAM2), spécifiques à la région anatomique. Le degré de corrélation entre les scores a été évalué par le coefficient de corrélation de Pearson. L'analyse graphique des variances a été utilisée pour le choix de tests paramétriques versus non paramétriques. Des tests non paramétriques, le Kruskal-Wallis pour éliminer l'hypothèse nulle et le Mann-Whitney pour la comparaison entre les scores deux à deux, ont été utilisés. Résultats: Une différence significative (p<.005) a été démontrée entre le CAIS et l'AOFAS (p=.0002), entre le CAIS et le FAAM1 (p=.0001) et entre le CAIT et l'AOFAS (p=.0003) Conclusions: Cette étude compare les performances de quatre scores dont deux spécifiques à la région anatomique et deux spécifiques à la pathologie. Nous avons démontré une bonne corrélation entre les scores ainsi que des différences significatives entre les résultats obtenus par chacun d'eux. Les résultats obtenus par les scores spécifiques à la pathologie semblent être plus précis que ceux obtenus par les scores spécifiques à la région anatomique. De plus, nous avons mis en évidence une forte corrélation entre l'AOFAS et les autres scores. Le FAAM semble être un bon compromis car il offre la possibilité, du fait de ses deux parties, d'évaluer le résultat en fonction de la demande fonctionnelle du patient. Perspectives: Un algorithme est proposé qui permet d'évaluer la littérature spécifique de manière plus critique et peut s'adapter également à la recherche et à la clinique relative à d'autres pathologies du pied et de la cheville

Pluralized life courses? An exploration of the life trajectories of individuals with psychiatric disorders.

BACKGROUND: : Most of the existing research relating to the life courses of people with psychiatric symptoms focuses on the occurrence and the impact of non-normative events on the onsets of crises; it usually disregards the more regular dimensions of life, such as work, family and intimate partnerships that may be related to the timing and seriousness of psychiatric problems. An additional reason for empirically addressing life trajectories of individuals with psychiatric problems relates to recent changes of family and occupational trajectories in relation to societal trends such as individualization and pluralization of life courses.¦AIM: : This paper explores the life trajectories of 86 individuals under clinical supervision and proposes a typology of their occupational, co-residence and intimacy trajectories. The results are discussed in light of the life-course paradigm.¦METHOD: : A multidimensional optimal matching analysis was performed on a sample of 86 individuals under clinical supervision to create a typology of trajectories. The influence of these trajectories on psychiatric disorders, evaluated using a SCL-90-R questionnaire, was then assessed using linear regression modelling.¦RESULTS: : The typologies of trajectories showed that the patients developed a diversity of life trajectories. Individuals who have developed a standard life course with few institutionalization periods reported more symptoms and distress than individuals with an institutionalized life trajectory.¦CONCLUSION: : The results of this study stress that psychiatric patients are social actors who are influenced by society at large and its ongoing process of change. Therefore, it is essential to take into account the diversity of occupational and family trajectories when dealing with individuals in therapeutic settings.

Dietary and lifestyle interventions in the management of the metabolic syndrome: present status and future perspective.

OBJECTIVE: To review the mechanisms underlying the metabolic syndrome, or syndrome X, in humans, and to delineate dietary and environmental strategies for its prevention. DESIGN: Review of selected papers of the literature. RESULTS: Hyperinsulinemia and insulin resistance play a key role in the development of the metabolic syndrome. Strategies aimed at reducing insulin resistance may be effective in improving the metabolic syndrome. They include low saturated fat intake, consumption of low-glycemic-index foods, physical exercise and prevention of obesity. CONCLUSIONS: Future research, in particular the genetic basis of the metabolic syndrome and the interorgan interactions responsible for insulin resistance, is needed to improve therapeutic strategies for the metabolic syndrome.

Management of refractory status epilepticus in adults: still more questions than answers.

Refractory status epilepticus (RSE) is defined as status epilepticus that continues despite treatment with benzodiazepines and one antiepileptic drug. RSE should be treated promptly to prevent morbidity and mortality; however, scarce evidence is available to support the choice of specific treatments. Major independent outcome predictors are age (not modifiable) and cause (which should be actively targeted). Recent recommendations for adults suggest that the aggressiveness of treatment for RSE should be tailored to the clinical situation. To minimise intensive care unit-related complications, focal RSE without impairment of consciousness might initially be approached conservatively; conversely, early induction of pharmacological coma is advisable in generalised convulsive forms of the disorder. At this stage, midazolam, propofol, or barbiturates are the most commonly used drugs. Several other treatments, such as additional anaesthetics, other antiepileptic or immunomodulatory compounds, or non-pharmacological approaches (eg, electroconvulsive treatment or hypothermia), have been used in protracted RSE. Treatment lasting weeks or months can sometimes result in a good outcome, as in selected patients after encephalitis or autoimmune disorders. Well designed prospective studies of RSE are urgently needed.

Pacemakers and magnetic resonance imaging: Current status and survey in Switzerland.

Electromagnetic fields arising from magnetic resonance imaging (MRI) can cause various clinically relevant functional disturbances in patients with cardiac pacemakers. Consequently, an implanted pacemaker is generally considered a contraindication for an MRI scan. With approximately 60 million MRI scans performed worldwide per year, MRI may be indicated for an estimated majority of pacemaker patients during the lifetime of their pacemakers. The availability of MR conditional pacemakers with CE labelling is of particular advantage since they allow the safe use of pacemakers in MRI. In this article the current state of knowledge on pacemakers and MR imaging is discussed. We present the results of a survey conducted among Swiss radiologists to assess current practice in patients with pacemakers.

Clinical and pathological importance of vacA allele heterogeneity and cagA status in peptic ulcer disease in patients from North Brazil

We have examined the prevalence of gene cagA and vacA alleles in 129 patients, 69 with gastritis and 60 with peptic ulcer diseases from North Brazil and their relation with histopathological data. vacA and cagA genotype were determined by polymerase chain reaction. Hematoxylin-eosin staining was used for histological diagnosis. 96.6% of the patients were colonized by Helicobacter pylori strains harboring single vacA genotype (nont-mixed infection). Among them, 11.8% had subtype s1a, 67.8% had subtype s1b, and 17% subtype s2. In regard to the middle region analysis, m1 alleles were found in 75.4% and m2 in 21.2% of patients. The cagA gene was detected in 78% patients infected with H. pylori and was associated with the s1-m1 vacA genotype. The H. pylori strains, vacA s1b m1/cagA-positive, were associated with increased risk of peptic ulcer disease and higher amounts of lymphocytic and neutrophilic infiltrates and the presence of intestinal metaplasia. These findings show that cagA and vacA genotyping may have clinical relevance in Brazil.

The health status of children without a resident permit consulting the Children's Hospital of Lausanne

Rapport de synthèseObjectif: Evaluer les données sociales, économiques et médicales concernant les enfants sans permis de séjour pris en charge à l'Hôpital de l'Enfance afin de pouvoir mieux comprendre leurs besoins spécifiques.Conclusions: La majorité des enfants ayant participé à l'étude sont originaires d'Amérique Latine et vivent dans des conditions de vie très précaires. Leur état de santé global est satisfaisant et la plupart bénéficient d'un suivi médical régulier. La prévention ciblée sur une meilleure hygiène de vie est particulièrement importante en raison de l'incidence élevée de sur poids et d'obésité dans cette population. Ce qui est connu et ce que l'étude apporte de nouveau: Cette étude est la 1ère qui analyse la situation socio-économique et l'état de santé d'enfants sans?papiers en Suisse. Les points forts de cette étude sont son caractère prospectif et le suivi de plus de la moitié de ces enfants à 1 an malgré une population particulièrement vulnérable et difficile à monitorer.Méthode: Etude exploratoire prospective par le biais d'un questionnaire incluant des données socio-démographiques, médicales et scolaires de 103 enfants sans permis de séjour ayant consulté pour la 1ère fois l'Hôpital de l'Enfance entre août 2003 et mars 2006. Ces enfants étaient ensuite reconvoqués pour une deuxième consultation 1 année plus tard afin d'obtenir un suivi médical.Résultats principaux: 87% des enfants sont originaires d'Amérique Latine, 36% ont moins de 2 ans. Cette population vit dans des conditions précaires avec un revenu familial sous le seuil de pauvreté (89% des familles vivent avec moins de 3100.- CHF/mois). Les raisons principales de consultation étaient des maladies infectieuses, un bilan de santé demandé par l'école ou un contrôle du nourrisson. La plupart des enfants étaient en bonne santé ou présentaient les mêmes pathologies retrouvées chez des enfants d'un âge similaire. 13% des enfants entre 2 et 16 ans sont obèses et 27% souffrent de surpoids. Tous les enfants en âge d'être scolarisés fréquentent l'école dans l'année suivant le 1er contrôle médical et 48% sont assurés auprès d'une assurance maladie.Biais: Au contrôle medical à 1 an, nous n'avions pas de donnée supplémentaire concernant 43% des enfants qui avaient été perdus de vue (courrier envoyé revenu en retour).

Volemic status influences the response of plasma atrial natriuretic factor to positive airway pressure.

STUDY OBJECTIVE; To evaluate interactive effects of volemic status and positive end-expiratory pressure (PEEP) on the plasma levels of atrial natriuretic factor (ANF) in assist-controlled mechanical ventilation (MV). DESIGN: Three successive protocols applied in randomized order to each participant. SETTING: Clinical investigation laboratory. PARTICIPANTS: Twenty-one young, healthy adults. INTERVENTIONS: The three protocols were as follows: (1) MV+PEEP, normovolemia; (2) MV+PEEP, hypervolemia; and (3) spontaneous breathing (SB), hypervolemia. In protocols 1 and 2, a preliminary period of SB lasting 2 h was followed by MV alone (0.5 h), MV+20 cm H2O PEEP (1 h), and a recovery period of SB (1.5 h). Hypervolemia was induced by the continuous i.v. infusion of 3 L of 0.9% NaCl in 5 h (protocols 2 and 3). MEASUREMENTS AND RESULTS: Heart rate, BP, and the plasma levels of immunoreactive ANF and catecholamines were measured serially. During hypervolemia, ANF significantly decreased when PEEP was added to MV (protocol 2: from 31.1 +/- 2.7 to 20.7 +/- 1.5 fmol/mL; p < 0.01). This did not occur in normovolemia (protocol 1: from 20.0 +/- to 16.7 +/- 1.2 fmol/mL; p = NS). The different effects of MV+PEEP in normovolemia and hypervolemia were not related to differences in circulating catecholamine levels. CONCLUSIONS: These results demonstrate for the first time (to our knowledge) that volemic status modulates the response of plasma ANF to PEEP in humans. The role of ANF in the water and salt retention induced by MV with PEEP might be limited to hypervolemic conditions.

Taeniasis-cysticercosis in Southern Ecuador: assessment of infection status using multiple laboratory diagnostic tools

Taenia solium-taeniasis and cysticercosis were studied in the human and porcine populations of a rural community in the Southern Ecuadorian Andes. From the 1059 inhabitants, 800 serum samples and 958 stool samples could be collected. In addition, 646 from the estimated 1148 pigs were tongue inspected. Circulating antigen was detected by enzyme linked immunosorbent assay (Ag-ELISA) in 2.25% of the human population, whereas intestinal taeniasis was detected in 1.46% by the formalin-ether technique. Following treatment and recovery of tapeworm fragments these were all identified as T. solium. Porcine cysticercosis was diagnosed in 3.56% of the pigs by tongue inspection. In addition, enzyme linked immunoelectrotransfer blot (EITB) was performed on a subset group of 100 humans to confirm the results of the Ag-ELISA. One hundred serum samples from pigs were also analysed by EITB. It appeared that 43 and 74% of humans and pigs had antibodies against T. solium cysticerci, respectively. It is concluded that contrary to the high exposure of the human population to T. solium that is suggested by EITB, the number of active cysticercosis cases, diagnosed by Ag-ELISA, was low, which may indicate endemic stability. The further use of complementary diagnostic methods for a better understanding of the epidemiology of T. solium is suggested.

Douleurs neuropathiques : quelques pistes pour une évaluation structurée et une prise en charge spécifique et globale [Neuropathic pain: tips and tools for specific and comprehensive pain management]

Les syndromes neuropathiques sont caractérisés par une douleur d'intensité élevée, de longue durée et résistante aux analgésiques classiques. De fait, il existe un risque important de répercussions sur la vie et le bien-être des patients. A travers une vignette clinique, cet article abordera le diagnostic, le traitement spécifique et l'impact de la douleur neuropathique sur la qualité de vie et les conséquences psychologiques associées, comme la dépression et l'anxiété. Nous présenterons des outils validés qui permettent d'objectiver la composante neuropathique aux douleurs et les comorbidités psychiatriques associées. Cette évaluation globale favorise un meilleur dialogue avec les patients ainsi que l'élaboration de stratégies thérapeutiques, notamment par le biais d'antidépresseurs, dont l'efficacité sera discutée en fin d'article. Neuropathic pain syndromes are characterized by intense and long lasting pain that is resistant to usual analgesics. Patients are therefore at high risk of decreased quality of life and impaired well-being. Using a case report, we will consider in this article the diagnosis and treatment of neuropathic pain as well as its impact on the quality of life including psychological consequences such as depression and anxiety. We will present simple and reliable scales that can help the general practitioner evaluate the neuropathic component of the pain syndrome and its related psychiatric co-morbidities. This comprehensive approach to pain management should facilitate communication with the patient and help the practitioner select the most appropriate therapeutic strategy, notably the prescription of antidepressants, the efficacy of which we will discuss at the end of the article.

Association of insecticide use and alteration on Aedes aegypti susceptibility status

Dengue and dengue hemorrhagic fever, vector-borne diseases transmitted by the mosquito Aedes aegypti, are presently important public health problems in Brazil. As the strategy for disease control is based on vector control through the use of insecticides, the development of resistance is a threat to programs efficacy. The objective of this study was to compare the Aedes aegypti susceptibility in nine vector populations from the state of São Paulo and seven from Northeast region of Brazil, since there was a difference on group of insecticide used between the areas. Bioassays with larvae and adult were performed according to the World Health Organization methods.The results showed higher resistance levels to organophosphates group in populations from the Northeast region where this group was used for both larvae and adult control than in São Paulo where organophosphates were used for larvae and pyretroids for adult control. Resistance to pyretroids in adults was widespread in São Paulo after ten years of use of cypermethrin while in vector populations from the Northeast region it was punctual. The difference in resistance profile between the areas is in accordance to the group of insecticide used.
