Vital capacity evolution in patients treated with the CMCR brace: statistical analysis of 90 scoliotic patients treated with the CMCR brace

<p>Summary</p> <p>Objective</p> <p>To study the evolution of pulmonary capacity during orthopaedic treatment of scoliosis with the CMCR brace.</p> <p>Background</p> <p>Investigating the impact of moderate scoliosis on respiratory capacity and its evolution during CMCR brace treatment with mobile pads.</p> <p>Context</p> <p>Several studies demonstrate the impact of scoliosis on respiratory capacity but few of them focus on the impact of bracing treatment. We studied the evolution of the pulmonary capacity of a cohort of 90 scoliotic patients.</p> <p>Methods</p> <p>This retrospective study included 90 scoliotic patients treated since 1999 with a brace with mobile pads called CMCR (n = 90; mean age: 13 years; 10-16). These patients were diagnosed with an idiopathic scoliosis (mean angulation 20.6°). All patients underwent a radiographic and respiratory evaluation at the beginning, the middle and the end of treatment.</p> <p>Results</p> <p><it>Mean age at treatment start was </it>13. Before treatment, our patients did not have a normal pulmonary capacity: Forced Vital Capacity (FVC) was only 75% of the theoretical value. All curvature types (thoracic, thoraco-lumbar and combined scoliosis) involved this reduced pulmonary capacity, with moderate-angulated scoliosis having a negative impact. At the beginning of brace treatment, the loss of real vital capacity with brace (0.3 litres) was 10% lower than without brace.</p> <p>At CMCR removal, the FVC had increased by 0.4 litre (21% +/- 4.2% compared to the initial value). The theoretical value had increased by 3%. This positive evolution was most important in girls at a low Risser stage (0,1,2), and before 11 years of age.</p> <p>Conclusion</p> <p>These results supported our approach of orthesis conception for adolescent idiopathic scoliosis which uses braces with mobile pads to preserve thorax and spine mobility.</p

A comprehensive overview of radioguided surgery using gamma detection probe technology

The concept of radioguided surgery, which was first developed some 60 years ago, involves the use of a radiation detection probe system for the intraoperative detection of radionuclides. The use of gamma detection probe technology in radioguided surgery has tremendously expanded and has evolved into what is now considered an established discipline within the practice of surgery, revolutionizing the surgical management of many malignancies, including breast cancer, melanoma, and colorectal cancer, as well as the surgical management of parathyroid disease. The impact of radioguided surgery on the surgical management of cancer patients includes providing vital and real-time information to the surgeon regarding the location and extent of disease, as well as regarding the assessment of surgical resection margins. Additionally, it has allowed the surgeon to minimize the surgical invasiveness of many diagnostic and therapeutic procedures, while still maintaining maximum benefit to the cancer patient. In the current review, we have attempted to comprehensively evaluate the history, technical aspects, and clinical applications of radioguided surgery using gamma detection probe technology

Results of two years of microbiological survey on food in enterprise restaurants

La méthode d’analyse NO.RE.CO.IN (normalisée, répétitive, codée et intégrée) proposée antérieurement, a été appliquée à 200 restaurants d’entreprises pendant les 8 trimestres des années 1978 et 1979. Grâce aux notations trimestrielles obtenues, les performances des 9 groupes étudiés ont pu être comparées objectivement, ce qui a permis d’estimer que la méthode expérimentée donnait satisfaction et méritait d’être recommandée.The analysis method NO.RE.CO.IN (normalized, repeatitive, coded and integrated) was proposed previously and was applied for 200 enter prise restaurants during 8 quarters of the years 1978 and 1979. With the quarterly notes stated, it was possible to compare objectively the scores of 9 groups studied, so that is was estimated that the experimented method gived satisfaction and merited to be recommended

Genome-wide analysis of parent-of-origin effects in non-syndromic orofacial clefts

Contains fulltext : 138097.pdf (publisher's version ) (Closed access)Parent-of-origin (PofO) effects, such as imprinting are a phenomenon where the effect of variants depends on parental origin. Conventional association studies assume that phenotypic effects are independent of parental origin, and are thus severely underpowered to detect such non-Mendelian effects. Risk of orofacial clefts is influenced by genetic and environmental effects, the latter including maternal-specific factors such as perinatal smoking and folate intake. To identify variants showing PofO effects in orofacial clefts we have used a modification of the family-based transmission disequilibrium test to screen for biased transmission from mothers and fathers to affected offspring, biased ratios of maternal versus paternal transmission, and biased frequencies of reciprocal classes of heterozygotes among offspring. We applied these methods to analyze published genome-wide single-nucleotide polymorphism (SNP) data from approximately 2500 trios mainly of European and Asian ethnicity with non-syndromic orofacial clefts, followed by analysis of 64 candidate SNPs in a replication cohort of approximately 1200 trios of European origin. In our combined analysis, we did not identify any SNPs achieving conventional genome-wide significance (P<5 x 10(-8)). However, we observed an overall excess of loci showing maternal versus paternal transmission bias (P=0.013), and identified two loci that showed nominally significant effects in the same direction in both the discovery and replication cohorts, raising the potential for PofO effects. These include a possible maternal-specific transmission bias associated with rs12543318 at 8q21.3, a locus identified in a recent meta-analysis of non-syndromic cleft (maternal-specific P=1.5 x 10(-7), paternal-specific P=0.17). Overall, we conclude from this analysis that there are subtle hints of PofO effects in orofacial clefting
