    [A Familial Non Medullary Thyroid Carcinoma (FNMTC) : a clinical and genetic update].
    Rev Med Liege 2016 Dec;71(12):557-561
    Service d'Endocrinologie, CHU de Liège, Site du Sart Tilman, Liège, Belgique.
    The syndrome of Familial Non Medullary Thyroid Carcinoma (FNMTC) includes two or more patients with an isolated non-medullary thyroid cancer (papillary, follicular, anaplastic) within the same family. To diagnose FNMTC, the clinician must exclude a syndromic presentation such as the syndromes of Cowden, Gardner or Werner, and the Carney Complex. Up to now, a hundred families with FNMTC have been genetically studied, including forms with (Ch19p13. Read More

    Accelerated epigenetic aging in Werner syndrome.
    Aging (Albany NY) 2017 Apr 4. Epub 2017 Apr 4.
    Department of Human Genetics, David Geffen School of Medicine, University of California Los Angeles, Los Angeles, CA 90095, USA.
    Individuals suffering from Werner syndrome (WS) exhibit many clinical signs of accelerated aging. While the underlying constitutional mutation leads to accelerated rates of DNA damage, it is not yet known whether WS is also associated with an increased epigenetic age according to a DNA methylation based biomarker of aging (the "Epigenetic Clock"). Using whole blood methylation data from 18 WS cases and 18 age matched controls, we find that WS is associated with increased extrinsic epigenetic age acceleration (p=0. Read More

    Are "normal hips" being labeled as femoroacetabular impingement due to EE angle?
    Medicine (Baltimore) 2017 Mar;96(13):e6410
    aDepartment of Sports Medicine and Rehabilitation, Peking University Shenzhen Hospital bNanshan Maternity & Child Healthcare Hospital of Shenzhen, Shenzhen, China.
    Gluteal muscle contracture (GMC) is a clinical syndrome characterized by gait abnormality and limb dysfunction, as well as secondary deformities of pelvis and femur. Femoroacetabular impingement (FAI) typically could be diagnosed on the basis of computed tomography (CT) such as the equatorial-edge angle (EE angle), but it did not work well in GMC patients. In this study, we retrospected all image data and found small EE angles in GMCs, which meant retroverted acetabulum; however, none of them showed no symptoms and signs of FAI. Read More

    A helical bundle in the N-terminal domain of the BLM helicase mediates dimer and potentially hexamer formation.
    J Biol Chem 2017 Apr 22;292(14):5909-5920. Epub 2017 Feb 22.
    From the College of Life Sciences, Northwest A&F University, Yangling, Shaanxi 712100, China,
    Helicases play a critical role in processes such as replication or recombination by unwinding double-stranded DNA; mutations of these genes can therefore have devastating biological consequences. In humans, mutations in genes of three members of the RecQ family helicases (blm, wrn, and recq4) give rise to three strikingly distinctive clinical phenotypes: Bloom syndrome, Werner syndrome, and Rothmund-Thomson syndrome, respectively. However, the molecular basis for these varying phenotypic outcomes is unclear, in part because a full mechanistic description of helicase activity is lacking. Read More

    WRN is recruited to damaged telomeres via its RQC domain and tankyrase1-mediated poly-ADP-ribosylation of TRF1.
    Nucleic Acids Res 2017 Apr;45(7):3844-3859
    University of Pittsburgh Cancer Institute, University of Pittsburgh School of Medicine, 5117 Centre Avenue, Pittsburgh, PA 15213, USA.
    Werner syndrome (WS) is a progeroid-like syndrome caused by WRN gene mutations. WS cells exhibit shorter telomere length compared to normal cells, but it is not fully understood how WRN deficiency leads directly to telomere dysfunction. By generating localized telomere-specific DNA damage in a real-time fashion and a dose-dependent manner, we found that the damage response of WRN at telomeres relies on its RQC domain, which is different from the canonical damage response at genomic sites via its HRDC domain.

    Is There an Association Between Hemoglobin A1C and Deep Postoperative Infection After TKA?
    Clin Orthop Relat Res 2017 Jan 23. Epub 2017 Jan 23.
    Department of Orthopaedic Surgery, University of Virginia Health System, PO Box 800159 HSC, Charlottesville, VA, 22908, USA.
    Background: Despite substantial research into the use of glycemic markers to stratify infection risk in patients with diabetes mellitus, there is little evidence to support a perioperative hemoglobin A1c (HbA1c) level associated with an increased risk of deep postoperative infection after TKA.

    Questions/purposes: (1) Is there an association between perioperative HbA1c level in patients with diabetes and deep postoperative infection after primary TKA? (2) Is the perioperative HbA1c level in patients with diabetes a useful test as an independent predictor for postoperative infection after TKA?

    Methods: We queried the PearlDiver Patient Records Database Humana dataset for patients who underwent primary TKA. This is a for-fee insurance patient-records database that contains records for more than 20 million patients with orthopaedic diagnoses from 2007 to the second quarter of 2015. Read More

    Methods: The ability of C1INH to control the inflammatory processes was studied in vitro and in vivo. Read More

    Pyometra and Pregnancy with Herlyn-Werner-Wunderlich Syndrome.
    Rev Bras Ginecol Obstet 2016 Dec 21;38(12):623-628. Epub 2016 Dec 21.
    Department of Obstetrics and Gynecology and Department of Maternal Fetal Medicine, Hospital Dr. José de Almeida, Lisbon, Portugal.
    We describe a Herlyn-Werner-Wunderlich syndrome (HWWS) patient with previous history of infertility who got pregnant without treatment and presented a pyometra in the contralateral uterus throughout the gestational period, despite multiple antibiotic treatments. Due to the uterus' congenital anomaly and the possibility of ascending infection with subsequent abortion, this pregnancy was classified as high-risk. We believe that the partial horizontal septum in the vagina may have contributed to the closure of the gravid uterus cervix, thus ensuring that the pregnancy came to term, with an uneventful vaginal delivery.

A total of 3,741 unique base pair-level variants were identified, across 17,605 potential mutation sites. Read More

    The Werner Syndrome Helicase Coordinates Sequential Strand Displacement and FEN1-Mediated Flap Cleavage during Polymerase δ Elongation.
    Mol Cell Biol 2017 Feb 19;37(3). Epub 2017 Jan 19.
    Department of Molecular Microbiology and Immunology, Institute for Genetic Medicine, Keck School of Medicine, University of Southern California, Los Angeles, California, USA
    The Werner syndrome protein (WRN) suppresses the loss of telomeres replicated by lagging-strand synthesis by a yet to be defined mechanism. Here, we show that whereas either WRN or the Bloom syndrome helicase (BLM) stimulates DNA polymerase δ progression across telomeric G-rich repeats, only WRN promotes sequential strand displacement synthesis and FEN1 cleavage, a critical step in Okazaki fragment maturation, at these sequences. Helicase activity, as well as the conserved winged-helix (WH) motif and the helicase and RNase D C-terminal (HRDC) domain play important but distinct roles in this process. Read More

    WRN-targeted therapy using inhibitors NSC 19630 and NSC 617145 induce apoptosis in HTLV-1-transformed adult T-cell leukemia cells.
    J Hematol Oncol 2016 Nov 9;9(1):121. Epub 2016 Nov 9.
    Department of Pathology and Laboratory Medicine, Center for Viral Oncology, University of Kansas Medical Center, 3901 Rainbow Boulevard, Kansas City, KS, 66160, USA.
    Background: Human T-cell leukemia virus type 1 (HTLV-1) infection is associated with adult T-cell leukemia/lymphoma (ATLL), a lymphoproliferative malignancy with a dismal prognosis and limited therapeutic options. Recent evidence shows that HTLV-1-transformed cells present defects in both DNA replication and DNA repair, suggesting that these cells might be particularly sensitive to treatment with a small helicase inhibitor. Because the "Werner syndrome ATP-dependent helicase" encoded by the WRN gene plays important roles in both cellular proliferation and DNA repair, we hypothesized that inhibition of WRN activity could be used as a new strategy to target ATLL cells.

    Neurodegeneration in accelerated aging.
    Dan Med J 2016 Nov;63(11)
    The growing proportion of elderly people represents an increasing economic burden, not least because of age-associated diseases that pose a significant cost to the health service. Finding possible interventions to age-associated disorders therefore have wide ranging implications. A number of genetically defined accelerated aging diseases have been characterized that can aid in our understanding of aging. Read More

    Familial non-medullary thyroid cancer (FNMTC) constitutes 3-9% of all thyroid cancers. Out of all FNMTC cases, only 5% in the syndromic form has well-studied driver germline mutations. These associated syndromes include Cowden syndrome, familial adenomatous polyposis, Gardner syndrome, Carney complex type 1, Werner syndrome and DICER1 syndrome. Read More

    Laparoscopic Hemi-hysterectomy and Trachelectomy in a Case of Herlyn-Werner-Wunderlich Syndrome.
    Surg Technol Int 2016 Oct;XXIX:181-184
    Department of Obstetrics and Gynecology, University of South Florida Morsani College of Medicine, Tampa, Florida.
    Background: Herlyn-Werner-Wunderlich Syndrome (HWWS) is a rare Müllerian anomaly characterized by uterus didelphys coexisting with an obstructed hemivagina and ipsilateral renal agenesis.

    Case: A 13-year-old female presented one-year after menarche with severe dysmenorrhea and a right-sided pelvic mass. Imaging identified a right uterus with hematometra, hematocolpos, absent right kidney, normal left kidney, ureter, left uterus, and vagina compressed to the left by right hematocolpos. Read More

    Genetic risk score based on the lifetime prevalence of femoral fracture in 924 consecutive autopsies of Japanese males.
    J Bone Miner Metab 2016 Nov 13;34(6):685-691. Epub 2015 Oct 13.
    Local Independent Administrative Agency, Tokyo Metropolitan Geriatric Hospital and Institute of Gerontology, Tokyo, Japan.
    A genetic risk score (GRS) was developed for predicting fracture risk based on lifetime prevalence of femoral fractures in 924 consecutive autopsies of Japanese males. A total of 922 non-synonymous single nucleotide polymorphisms (SNPs) located in 62 osteoporosis susceptibility genes were genotyped and evaluated for their association with the prevalence of femoral fracture in autopsy cases. GRS values were calculated as the sum of risk allele counts (unweighted GRS) or the sum of weighted scores estimated from logistic regression coefficients (weighted GRS). Read More

    The adaptive drop foot stimulator - Multivariable learning control of foot pitch and roll motion in paretic gait.
    Med Eng Phys 2016 Nov 7;38(11):1205-1213. Epub 2016 Jul 7.
    Control Systems Group, Technische Universität Berlin, Germany.
    Many stroke patients suffer from the drop foot syndrome, which is characterized by a limited ability to lift (the lateral and/or medial edge of) the foot and leads to a pathological gait. In this contribution, we consider the treatment of this syndrome via functional electrical stimulation (FES) of the peroneal nerve during the swing phase of the paretic foot. A novel three-electrodes setup allows us to manipulate the recruitment of m. Read More

    Periodontal Ehlers-Danlos Syndrome Is Caused by Mutations in C1R and C1S, which Encode Subcomponents C1r and C1s of Complement.
