    Spine-hip relations add understandings to the pathophysiology of femoro-acetabular impingement: A systematic review.
    Orthop Traumatol Surg Res 2017 Apr 1. Epub 2017 Apr 1.
    The MSK Lab, Charing Cross Campus, laboratory Block, London W6 8RP Imperial College, London, United Kingdom.
    Relationship between hip pathoanatomy and symptomatic FAI has been reported to be weak. This is explained by the reciprocal interaction between proximal femur and acetabular anatomies, but potentially also by the individual spine-hip relations (SHR). The key-answer for a complete understanding of the pathophysiology of FAI might lie in the comprehension of the SHRs, which have not yet been fully addressed. Read More

    The influence of spine-hip relations on total hip replacement: A systematic review.

    Am J Physiol Endocrinol Metab 2017 Feb 28:ajpendo.00464.2016. Epub 2017 Feb 28.
    CNR Institute of Clinical Physiology, University of Pisa.
    While hyper/hypothyroidism causes dysglycemia, the relationship between thyroid hormone levels within the normal range and insulin resistance (IR) is unclear. In 940 participants with strictly normal serum concentrations of free triiodothyronine (fT3), free thyroxine (fT4), and thyroid-stimulating hormone (TSH)) followed up for 3 years, we measured insulin sensitivity (by the insulin clamp technique) and a panel of 35 circulating metabolites. At baseline, across quartiles of increasing fT3 levels (or fT3/fT4 ratio) there emerged most features of IR (male sex, higher BMI, waist circumference, heart rate, blood pressure, fatty liver index, free fatty acids, and triglycerides levels, reduced insulin-mediated glucose disposal and ß-cell glucose sensitivity).

    Clinical and biological progress over 50 years in Rett syndrome.
    Nat Rev Neurol 2017 Jan 9;13(1):37-51. Epub 2016 Dec 9.
    Telethon Kids Institute, 100 Roberts Road, Subiaco, Perth, Western Australia 6008, Australia.
    In the 50 years since Andreas Rett first described the syndrome that came to bear his name, and is now known to be caused by a mutation in the methyl-CpG-binding protein 2 (MECP2) gene, a compelling blend of astute clinical observations and clinical and laboratory research has substantially enhanced our understanding of this rare disorder. Here, we document the contributions of the early pioneers in Rett syndrome (RTT) research, and describe the evolution of knowledge in terms of diagnostic criteria, clinical variation, and the interplay with other Rett-related disorders. We provide a synthesis of what is known about the neurobiology of MeCP2, considering the lessons learned from both cell and animal models, and how they might inform future clinical trials. Read More

    Exclusive expression of MeCP2 in the nervous system distinguishes between brain and peripheral Rett syndrome-like phenotypes.
    Hum Mol Genet 2016 Aug 9. Epub 2016 Aug 9.
    Institute of Neuroscience and Psychology, College of Medical, Veterinary & Life Sciences, University of Glasgow, Glasgow, UK
    Rett syndrome (RTT) is a severe genetic disorder resulting from mutations in the X-linked MECP2 gene. MeCP2 protein is highly expressed in the nervous system and deficiency in the mouse central nervous system alone recapitulates many features of the disorder. This suggests that RTT is primarily a neurological disorder, although the protein is reportedly widely expressed throughout the body. Read More

    Quantitative risk assessment of the likeihood of introducing porcine reproductive and respiratory syndrome virus into New Zealand through the importation of pig meat.
    Rev Sci Tech 2015 Dec;34(3):961-75
    A quantitative model was developed to estimate the likelihood of an incursion of porcine reproductive and respiratory syndrome virus (PRRSV) into New Zealand through the importation of fresh consumer-ready cuts of pig meat. A sensitivity analysis of all the inputs used in this model illustrated the importance of correctly modelling the available 'dose-response' data, and a mechanistic Beta-Poisson model was shown to be the most appropriate method for this in the authors' assessment. The output of this model predicts an average of approximately 1,200 years between PRRSV introductions resulting in primary infections in New Zealand. Read More

    Methods: Twenty-eight patients with severe and rigid scoliosis (Cobb angle>70° and flexibility<30%) were retrospectively enrolled between June 2008 and June 2010. The average age of the patients was 17. Read More

    Scoliosis in Children With Aicardi Syndrome.
    J Pediatr Orthop 2015 Jul-Aug;35(5):e38-42
    Division of Orthopaedic Surgery, The Children's Hospital of Philadelphia, Philadelphia, PA.
    Background: Aicardi syndrome (ACS) is a rare neurodevelopmental disorder that was classically characterized by the triad of agenesis of corpus callosum, infantile spasms, and chorioretinal lacunae. As new cases emerge and new common phenotypic features are being described in subsequent reports, new modified diagnostic criteria have been proposed that now classify the observed costovertebral abnormalities as supporting diagnostic features. To our knowledge there are no previous studies focusing and describing the scoliosis observed in children with ACS. Read More

    Exclusively epidural spinal metameric arteriovenous shunts: case report and literature review.
    Spine J 2015 Mar 29;15(3):e15-22. Epub 2014 Nov 29.
    Department of Neurosurgery, Graduate School of Medicine, Tohoku University, 1-1 Seiryo Aoba, Sendai 980-8574, Japan.
    Background Context: Spinal arteriovenous metameric syndrome (SAMS) is a subgroup of spinal arteriovenous malformations (AVMs). Most SAMS cases have intra- and extradural AVMs and suffer from hematomyelia, subarachnoid hemorrhage, or venous congestive myelopathy.

    Purpose: To present a rare case of SAMS in which spinal AVMs were exclusively epidural. Read More

    Biomechanical properties of bone in a mouse model of Rett syndrome.

    Rett syndrome (RTT) is an X-linked genetic disorder and a major cause of intellectual disability in girls. Mutations in the methyl-CpG binding protein 2 (MECP2) gene are the primary cause of the disorder. Despite the dominant neurological phenotypes, MECP2 is expressed ubiquitously throughout the body and a number of peripheral phenotypes such as scoliosis, reduced bone mineral density and skeletal fractures are also common and important clinical features of the disorder.

    Gait analysis in a Mecp2 knockout mouse model of Rett syndrome reveals early-onset and progressive motor deficits.
    PLoS One 2014 13;9(11):e112889. Epub 2014 Nov 13.
    Institute of Neuroscience and Psychology, College of Medical, Veterinary and Life Sciences, University of Glasgow, Glasgow, United Kingdom.
    Rett syndrome (RTT) is a genetic disorder characterized by a range of features including cognitive impairment, gait abnormalities and a reduction in purposeful hand skills. Mice harbouring knockout mutations in the Mecp2 gene display many RTT-like characteristics and are central to efforts to find novel therapies for the disorder. As hand stereotypies and gait abnormalities constitute major diagnostic criteria in RTT, it is clear that motor and gait-related phenotypes will be of importance in assessing preclinical therapeutic outcomes.
