Outcome of long-axis percutaneous sacroplasty as first-line treatment of sacral insufficiency fractures : P219

Purpose: To assess the clinical outcome of patients who were subjected to long-axis sacroplasty as first line treatment for sacral insufficiency fractures. Methods and materials: Nineteen patients with unilateral (n = 3) or bilateral (n = 16) sacral fractures were involved. Under local anaesthesia, each patient was subjected to CT guided sacroplasty using the long-axis approach through a single entry point. An average of 6 ml of PMMA was delivered along the path of each sacral fracture. For each individual patient, the VAS pain score before sacroplasty and at 1, 4, 24, and 48 weeks after the procedure was obtained. Furthermore, the use of analgesics (narcotic/non-narcotic) along with the evolution of post interventional patient mobility before and after sacroplasty was also recorded. Results: The mean pre-procedure VAS score was 8 ± 1.9. This has rapidly declined in the first week after the procedure (mean 4 ± 1.5) followed by gradual decrease along the rest of follow-up period at 4 weeks (mean 3 ± 1.2), 24 weeks (mean 2 ± 1.3), and 48 weeks (mean 1.3 ± 1.4), respectively. Eleven (58%) patients were under narcotic analgesia before sacroplasty, whereas, 8 (42%) patients were using non-narcotics. Corresponding values after the procedure were 2/19 (10%) (narcotic) and 10/19 53% (non-narcotic). Seven (37%) patients did not address post-procedure analgesic use. The evolution of post interventional mobility was favourable in the study group since they revealed a significant improvement in their mobility point scale. Conclusion: Long-axis percutaneous sacroplasty is a suitable minimally invasive treatment option for patients who present with sacral insufficiency fractures. Future studies with larger patient number are warranted to grasp any potential limitations of this therapeutic approach.

Long-term follow-up of four patients with Langer-Giedion syndrome: clinical course and complications.

Long-term observations of individuals with the so-called Langer-Giedion (LGS) or tricho-rhino-phalangeal type II (TRPS2) are scarce. We report here a on follow-up of four LGS individuals, including one first described by Andres Giedion in 1969, and review the sparse publications on adults with this syndrome which comprises ectodermal dysplasia, multiple cone-shaped epiphyses prior to puberty, multiple cartilaginous exostoses, and mostly mild intellectual impairment. LGS is caused by deletion of the chromosomal segment 8q24.11-q24.13 containing among others the genes EXT1 and TRPS1. Most patients with TRPS2 are only borderline or mildly cognitively delayed, and few are of normal intelligence. Their practical skills are better than their intellectual capability, and, for this reason and because of their low self-esteem, they are often underestimated. Some patients develop seizures at variable age. Osteomas on processes of cervical vertebrae may cause pressure on cervical nerves or dissection of cerebral arteries. Joint stiffness is observed during childhood and changes later to joint laxity causing instability and proneness to trauma. Perthes disease is not rare. Almost all males become bald at or soon after puberty, and some develop (pseudo) gynecomastia. Growth hormone deficiency was found in a few patients, TSH deficiency so far only in one. Puberty and fertility are diminished, and no instance of transmission of the deletion from a non-mosaic parent to a child has been observed so far. Several affected females had vaginal atresia with consequent hydrometrocolpos.

Intraobserver and interobserver variability of ascending aorta diameter as assessed with ECG-gated MDCT: automatic versus manual measurements

Purpose: Recently morphometric measurements of the ascending aorta have been done with ECG-gated MDCT to help the development of future endovascular therapies (TCT) [1]. However, the variability of these measurements remains unknown. It will be interesting to know the impact of CAD (computer aided diagnosis) with automated segmentation of the vessel and automatic measurements of diameter on the management of ascending aorta aneurysms. Methods and Materials: Thirty patients referred for ECG-gated CT thoracic angiography (64-row CT scanner) were evaluated. Measurements of the maximum and minimum ascending aorta diameters were obtained automatically with a commercially available CAD and semi-manually by two observers separately. The CAD algorithms segment the iv-enhanced lumen of the ascending aorta into perpendicular planes along the centreline. The CAD then determines the largest and the smallest diameters. Both observers repeated the automatic measurements and the semimanual measurements during a different session at least one month after the first measurements. The Bland and Altman method was used to study the inter/intraobserver variability. A Wilcoxon signed-rank test was also used to analyse differences between observers. Results: Interobserver variability for semi-manual measurements between the first and second observers was between 1.2 to 1.0 mm for maximal and minimal diameter, respectively. Intraobserver variability of each observer ranged from 0.8 to 1.2 mm, the lowest variability being produced by the more experienced observer. CAD variability could be as low as 0.3 mm, showing that it can perform better than human observers. However, when used in nonoptimal conditions (streak artefacts from contrast in the superior vena cava or weak lumen enhancement), CAD has a variability that can be as high as 0.9 mm, reaching variability of semi-manual measurements. Furthermore, there were significant differences between both observers for maximal and minimal diameter measurements (p<0.001). There was also a significant difference between the first observer and CAD for maximal diameter measurements with the former underestimating the diameter compared to the latter (p<0.001). As for minimal diameters, they were higher when measured by the second observer than when measured by CAD (p<0.001). Neither the difference of mean minimal diameter between the first observer and CAD nor the difference of mean maximal diameter between the second observer and CAD was significant (p=0.20 and 0.06, respectively). Conclusion: CAD algorithms can lessen the variability of diameter measurements in the follow-up of ascending aorta aneurysms. Nevertheless, in non-optimal conditions, it may be necessary to correct manually the measurements. Improvements of the algorithms will help to avoid such a situation.

Neuro-developmental follow-up of neonates treated with magnesium sulfate for persistent pulmonary hypertension

Rapport de synthèse : DEVENIR NEURO-DEVELOPPEMENTAL DE NOUVEAU-NES TRAITES PAR DU SULFATE DE MAGNESIUM POUR UNE HYPERTENSION PULMONAIRE PERSISTANTE L'hypertension pulmonaire persistante du nouveau-né (HTPP) est un trouble de l'adaptation post-natale de la circulation pulmonaire caractérisé par une défaillance de la diminution normale des résistances vasculaires pulmonaires, accompagné d'un shunt droite-gauche, résultant en une hypoxémie profonde. C'est une pathologie sévère nécessitant des soins intensifs avec un risque augmenté de handicaps neurologiques chez les survivants. Le traitement de l'HTPP du nouveau-né inclut une ventilation mécanique ainsi que différents agents pharmacologiques pour dilater les vaisseaux pulmonaires, dont le sulfate de magnésium (MgSO4) à hautes doses par voie intraveineuse et le monoxyde d'azote par voie inhalée (iN0). Le MgSO4 est une alternative thérapeutique de l'HTPP du nouveau-né avec peu d'effets secondaires et une mortalité basse. Il a aussi été démontré que le MgSO4 est un traitement de l'HTPP du nouveau-né autant efficace que le iN0 et moins coüteux. Des études sur le suivi neuro-développemental de nouveau-nés avec HTPP traités selon différentes méthodes ont été publiées reportant des taux élevés de handicaps majeurs et mineurs. Plus récemment, des études de suivi après traitement par iN0 ont montré des taux plus bas qu'avec des traitements antérieurs. Le devenir neuro-développemental àlong terme d'enfants traités avec du MgSO4 n'a pas été documenté. Le but de cette étude est de décrire le développement des enfants qui ont présenté une HTPP traitée seulement avec du MgS04, de reporter l'incidence de handicaps majeurs et mineurs, et de les comparer à un groupe contrôle d'enfants sains du même âge ainsi qu'aux données de la littérature. La population consiste en 33 nouveau-nés traités pour une HTPP avec seulement du MgSO4 (groupe étude) et 32 nouveau-nés à terme sains (groupe contrôle). Un suivi neurodéveloppemental standardisé et approfondi a été effectué aux âges clés de 18 mois et 5 ans. Les taux de handicaps majeurs à 18 mois et 5 ans dans le groupe étude étaient de 6% et 11,4% respectivement, et de 0% aux deux âges dans le groupe contrôle. Les taux de handicaps mineurs aux mêmes âges étaient de 3% et 26,9% pour le groupe étude, et de 0% et 26,1% pour le groupe contrôle. Les quotients développementaux moyens à 18 mois étaient de 106,6 (DS 1,6) dans le groupe étude et de 118,3 (DS 1,0) dans le groupe contrôle (P < 0,001). L'index général intellectuel en âge préscolaire était de 112.6 (DS 3.7), respectivement de 119.3 (DS 3.1 ), sans différence significative entre les deux groupes. A 18 mois, les taux de handicaps majeurs et mineurs dans les groupes études et contrôle étaient de 6% et 3%. Dans la littérature, des taux entre 0% et 33% ont été décrits. A cet âge, il y avait une différence significative pour tous les scores du test de Griffiths, mëme en tenant compte du status socio-économique de la famille. Ceci suggère un léger retard du développement global et non une altération spécifique. Ces différences n'étaient plus significatives en âge préscolaire, suggérant un rattrapage développemental. Le taux de handicaps majeurs en âge préscolaire pour le groupe étude était de 11.5%, sans aucune infirmité motrice cérébrale. Ces résultats correspondent à ceux d'études de suivi après d'autres traitements jusqu'à l'âge de 24 mois avec des taux variant de 0% à 15%. Le taux de handicaps mineurs était de 26.9% dans le groupe étude et de 26.1% dans le groupe contrôle, sans différence significative entre les deux groupes. L'incidence de handicaps mineurs dans le groupe étude était plutôt élevée en comparaison aux données de la littérature (6 à 22% à 6 ans). Une explication possible est que nous avons considéré des problèmes de langage et de comportement comme handicaps mineurs. Ceci suggère une différence méthodologique et non une plus mauvaise issue dans nos deux groupes. Les évaluations cognitives des enfants des deux groupes se trouvaient dans la norme, ce qui est aussi le cas dans la littérature. En conclusion, cette étude longitudinale non randomisée d'enfants traités avec du MgSO4 seul pour une HTPP sévère ne montre pas de conséquences sur le devenir neuro-développemental à long terme. Cette étude le démontre pour la première fois. Malgré le fait que iN0 soit le traitement actuellement recommandé pour l'HTPP du nopuveau-né, le MgSO4 reste largement utilisé, en particulier dans des pays en voie de développement. L'absence de complications neuro-développementales majeures à long terme permet de considérer l'administration du MgSO4 pour le traitement de l'HTPP du nouveau-né en cas de non réponse ou d'inaccessibilité au iNO.

Solitary fibrous tumor of the lateral ventricle: CT appearances and pathologic correlation with follow-up.

Intracranial solitary fibrous tumors are rare, and intraventricular fibrous tumors are even more unusual. We report a case of solitary fibrous tumor in the region of trigone and body of the left lateral ventricle and discuss the clinical presentation, CT characteristics, and histopathologic features with 1-year follow-up. We speculate that the tumor arose from the perivascular connective tissue of the choroid plexus.

Obesity Weighting up the Evidence: All-Island Multisectoral Conference on Obesity

The World Health Organization reports that overweight and obesity have reached epidemic proportions globally and estimates that approximately 1.6 billion adults and at least 20 million children under the age of five are overweight or obese. It is accepted that being overweight or obese increases the risk of health conditions such as heart disease, stroke, diabetes and some cancers and has significant impacts on a wide range of other factors including education, employment and emotional wellbeing. This conference aimed to present a multisectoral audience with the latest developments in overweight and obesity prevention and management. This presentation was given by Dr. Kevin Balanda, Institute of Public Health in Ireland. The Institute of Public Health in Ireland (IPH) is leading the development of an All-Ireland obesity observatory The obesity observatory development is being undertaken in collaboration with: - HRB Centre for Health and Diet Research ﾖ UCC /UCD - Centre of Excellence for Public Health (NI) - QUB Projected outcomes: Adequate sample size Data to be sought and recorded Usefulness of a database in influencing policy Value to clinicians in management of obesity

The role of ceramide trihexoside (globotriaosylceramide) in the diagnosis and follow-up of the efficacy of treatment of Fabry disease: a review of the literature.

Fabry disease is caused by a deficiency of a-galactosidase A which leads to the progressive intra-lysosomal accumulation of ceramide trihexoside (CTH), also known as globotriaosylceramide (Gb3), in different cell types and body fluids. The clinical manifestations are multisystemic and predominantly affect the heart, kidney and central nervous system. The role of CTH in the pathophysiological process of Fabry disease is not established, and the link between the degree of accumulation and disease manifestations is not systematic. The use of CTH as a diagnostic tool has been proposed for several decades. The recent introduction of a specific treatment for Fabry disease in the form of enzyme replacement therapy (ERT) has led to the need for a biological marker, in place of a clinical sign, for evaluating the efficacy of treatment and also as a tool for following the long term effects of treatment. The ideal biomarker must adhere to strict criteria, and there should be a correlation between the degree of clinical efficacy of treatment and a change in its concentration. This review of the literature assesses the utility of CTH as a diagnostic tool and as a marker of the efficacy of ERT in patients with Fabry disease. Several techniques have been developed for measuring CTH; the principles and the sensitivity thresholds of these methods and the units used to express the results should be taken into consideration when interpreting data. The use of CTH measurement in Fabry disease should be re-evaluated in light of recent published data.

Immunological evaluation of human immunedeficiency virus infected individuals by flow cytometry

Human immunodeficiency virus (HIV) infection heavily compromises the immune system. The decrease of the T cell CD4+ subset along the evolution to acquired immunodeficiency syndrome has been considered as a hallmark of HIV infection. In this paper we review some aspects of the immunopathology of HIV infection and discuss the importance of the flow cytometry for the evaluation of the T lymphocyte subsets in the follow-up of HIV infected children and adults, and for the monitoring of the immune reconstitution upon antiretroviral therapy.
