STUDY DESIGN: This is a report of a case. OBJECTIVE: To document the clinical, radiographic, and histologic characteristics of a lumbar extraforaminal juxtafacet cyst. SUMMARY OF BACKGROUND DATA: Spinal juxtafacet cysts develop most frequently at the dorsal aspect of the zygapophysial joint, sometimes in the posterolateral area of the canal. In one case, they have been described in the foraminal and extraforaminal region. METHODS: Description of the case report. RESULT: The authors report one case of a strictly extraforaminal juxtafacet cyst responsible for L5 sciatica. CONCLUSIONS: Juxtafacet cysts of the spine represent an infrequent cause of sciatica, usually when they grow in the canal, or more exceptionally when they occupy the foraminal or extraforaminal areas.

Parmi les techniques culture indépendante, le développement de l’ultra-séquençage a permis de positionner l’analyse métagénomique comme étant la meilleure alternative pour l’étude de microbiotes complexes. Durant ces trois dernières années, les études métagénomiques ont été consacrées essentiellement à l’analyse d’échantillons environnementaux. Ce travail décrit l’application de cette technique à l’étude des populations bactériennes de quatre types de fromages à pâte molle. Parmi ceux-ci, trois d’entre eux sont des fromages belges typiques à croute lavée (deux sont fabriqués avec du lait cru et le troisième avec du lait pasteurisé). Le quatrième est un fromage français crémeux à base de lait cru. Des analyses microbiologiques classiques et métagénomiques ciblant l’ADNr 16S ont été réalisées dans le cœur et sur la croute des quatre fromages, donnant un total de 8 échantillons. Au total, 48 genres et 163 espèces bactériennes ont été identifiées pour tous les échantillons. Comme attendu, Lactoccocus lactis subsp lactis et/ou cremoris sont les espèces les plus représentées dans le cœur des quatre fromages. Concernant la croute des fromages, les espèces bactériennes les plus abondantes sont Psychrobacter glacinola, Staphylococcus equorum, Corynebacterium casei et Marinilactibacillus psychrotolerans. A noter la présence de Brevibacterium spp et Psychroflexus spp qui permettent d’obtenir la couleur orangée de la croute. Toutes ces espèces sont présentes en différentes proportions suivant l’origine et le processus de fabrication et sont connues pour leurs propriétés technologiques et/ou organoleptiques. Les deux fromages belges au lait cru sont composés de beaucoup d’espèces bactériennes différentes. Tandis que le fromage au lait pasteurisé contient moins d’espèces, principalement Lactococcus lactis (97,6%) dans le cœur. Un résultat inattendu concerne la faible diversité bactérienne du fromage français crémeux à base de lait cru. Seulement deux espèces étaient majoritairement présentes : Lactoccocus lactis subsp cremoris et Leuconostoc citreum avec respectivement 94,9% et 4,9% dans le cœur et 93,8% et 5% dans la croute). Comparé avec les résultats des autres fromages à base de lait cru, ce résultat est particulièrement surprenant. Le microbiote des fromages joue un rôle central sur le processus de fabrication, les qualités organoleptiques et la durée de vie commerciale des produits. L’analyse métagénomique est devenu un outil puissant, rapide et abordable pour identifier, comprendre et maitriser les flores impliquées [less ▲]

Among the culture-independent techniques, ultra-sequencing has contributed to place metagenomic analysis as the best alternative to study complex microbiota. During the last three years, metagenomic studies were used essentially for environmental samples but it could be used also to analyse bacterial populations of food samples. This work describes the application of this technique to study the bacterial population of different types of soft cheeses. Among these, three of them are a typical Belgian soft cheese with washed rind (two with raw milk and the third with pasteurized milk). The fourth is a French creamy soft cheese made with raw milk. Classical microbiological and 16S rDNA metagenomic analysis were carried out in the core and on the rind of the four cheeses, giving a total of 8 samples. In total, 48 genus and 163 species were identified for all samples. As expected Lactoccocus lactis and/or cremoris are the most representative species in the core of the four cheeses. On the rind of cheeses, the predominant bacterial species are Psychrobacter glacinola, Staphylococcus equorum, Corynebacterium casei and Marinilactibacillus psychrotolerans. Brevibacterium spp and Psychroflexus spp are important for the rind of washed rind cheeses. All these species are present in different proportions following the origin and the cheese making process and they are well known for their organoleptic properties on the rind of cheese. The two Belgian soft cheese made with raw milk are composed of many more different bacterial species. While the cheese made from pasteurized milk contains less species mainly composed by Lactococcus lactis (97,6%) in the core. An unexpected result is the low diversity of the a French creamy soft cheese made with raw milk with only two predominent species : Lactoccocus cremoris and Leuconostoc citreum are present in the core (94,9% and 4,9% , respectively) and on the rind (93,8% and 5% , respectively). Compared with the other cheeses made with raw milk, this result is surprising. The bacterial cheese microbiota plays a central role in cheese-making. The subtleties of cheese character, as well as their shelf-life, are largely determined by the evolution of their microbiota. [less ▲]

The severity of initial brain damage is an important risk factor in determining the prognosis of head trauma. It can be assessed by assigning neurological scores or by determining the cerebrospinal fluid (CSF) activity of the isoenzyme creatine kinase-BB (CK-BB). In 10 severely head-injured patients serial CSF samples were obtained during the first 24 hours after trauma, and exponential decay of CK-BB activity with an average half-life of 4.5 hours was demonstrated. This finding led the authors to propose an "extrapolated" CK-BB activity, which theoretically occurs immediately after injury and is calculated from a single CK-BB recording, as a new index for assessing the degree of initial brain damage. In 50 patients with severe head injury, the prognostic ability of "observed" and "extrapolated" CK-BB activity was compared with two clinical scoring systems that evaluate severity of head trauma (the Glasgow and the Glasgow-Liege Coma Scales). "Extrapolated" CK-BB activity proved to be the best prognostic factor. With a CK-BB cutoff point of 330 U/liter, a true-positive rate of 79% and a true-negative rate of 73% were obtained. These results suggest the usefulness of measuring CK-BB activity in CSF as soon as possible after hospital admission for head injury. [less ▲]

Drugs used for the prevention and the treatment of osteoporosis exert various favourable and unfavourable extra-skeletal effects whose importance is increasingly recognized notably for treatment selection. INTRODUCTION: The therapeutic armamentarium for the prevention and the treatment of osteoporosis is increasingly large, and possible extra-skeletal effects of available drugs could influence the choice of a particular compound. METHODS: The present document is the result of a national consensus, based on a systematic and critical review of the literature. RESULTS: Observational research has suggested an inverse relationship between calcium intake and cardiovascular diseases, notably through an effect on blood pressure, but recent data suggest a possible deleterious effect of calcium supplements on cardiovascular risk. Many diverse studies have implicated vitamin D in the pathogenesis of clinically important non-skeletal functions or diseases, especially muscle function, cardiovascular disease, autoimmune diseases and common cancers. The possible effects of oral or intravenous bisphosphonates are well-known. They have been associated with an increased risk of oesophageal cancer or atrial fibrillation, but large-scale studies have not found any association with bisphosphonate use. Selective oestrogen receptor modulators have demonstrated favourable or unfavourable extra-skeletal effects that vary between compounds. Strontium ranelate has a limited number of non-skeletal effects. A reported increase in the risk of venous thromboembolism is not found in observational studies, and very rare cases of cutaneous hypersensitivity reactions have been reported. Denosumab has been introduced recently, and its extra-skeletal effects still have to be assessed. CONCLUSION: Several non-skeletal effects of bone drugs are well demonstrated and influence treatment choices. [less ▲]

OBJECTIVE: The systemic inflammatory response to cardiopulmonary bypass (CPB) possibly increases microvascular permeability to plasma proteins, leading to capillary leak syndrome. The study was conducted to elucidate any protein leakage in newborns using Evans blue dye as tracer. DESIGN: Prospective controlled study. SETTING: University-affiliated heart center. PARTICIPANTS: Eleven neonates with transposition of the great arteries. INTERVENTIONS: Plasma interleukin-6 (IL-6), IL-10, fractional escape rate (FER) of an intravenous bolus of Evans blue, and colloid osmotic pressure (COP) were assessed before and after surgery (statistics: median and 25th-75th percentile, Friedman's 2-way analysis of variance, and Wilcoxon matched-pairs signed-rank test [before and after surgery]). MEASUREMENTS AND MAIN RESULTS: All patients had an uneventful intraoperative course. The demographic and operative data were age 11 (10-13) days, body weight 3.2 (3.0-3.3) kg, CPB time 132 (123-144) minutes, and aortic cross-clamp time 66 (64-78) minutes. The proinflammatory IL-6 increased 60-fold and the anti-inflammatory IL-10 only 3-fold after CPB. FER, however, was not changed, whereas COP was significantly reduced after CPB. CONCLUSIONS: In contrast to the expectation, the escape rate of Evans blue, reflecting the extravasation of albumin, was not increased after CPB. However, reduced COP, hypothermia, and also a reduced lymphatic drainage may contribute to edema formation. The present data do not support the hypothesis of a capillary leak after CPB in newborns.
