Vasilios and Angeliki, who convinced me to pursue my dreams and that everything is possible To my patients who trust me with their health and teach me something new every single day Foreword Fellowship training is a wonderful start to mastering the art and science of rheumatology Yet, or 3  years of rheumatology fellowship training can be dizzying for the notable volume of work, experiences, knowledge, diagnoses, controversies, and opportunities The educational sustenance is analogous to drinking from the firehose You’ll definitely get wet (experience) but your thirst may go unquenched Time, perspective, and an ongoing effort to learning are necessary to master the art of rheumatology Absolute Rheumatology Review is a new source of perspective and knowledge for the young rheumatologist It was designed to be the resource for those in training and those preparing for board examinations or recertification examinations Textbooks serve the important role of defining the standards of care and where we are in our understanding of rheumatic disorders This is especially important with complex rheumatologic disorders where innovation, pathogenic advances, and new therapeutics change annually When such knowledge is applied, patients win with better opportunities for an early diagnosis and optimal outcome The chapters included in Absolute Rheumatology Review are written by experts who have synthesized historical perspective and recent advances to provide overviews that are accurate, focused, practical, and up-to-date In reviewing and reading Dr Efthimiou’s textbook, I can appreciate the selection of authors and the inclusion of many novel chapters germane to rheumatology, including genetics, immunology, epidemiology, regional musculoskeletal disorders, ultrasound, and autoinflammatory disorders These stand well beside chapters on the most prevalent disorders, such as rheumatoid arthritis, psoriatic arthritis, osteoarthritis, etc Chapter design and readability are both easy and incisive The chapters are led by bulleted key points and finish with test questions to further their educational impact These are novel, well-done, and highly helpful whether you’re a young rheumatologist preparing for board questions or a practicing rheumatologist wishing to stay abreast of the field vii viii Foreword While this compendium will benefit those who are studying rheumatology, it can also exist as a valued source for the rheumatologist engaged in patient care, especially when he or she ponders the last patient, the next drug choice, or the best diagnostic approach John J. Cush, MD Clinical Professor of Internal Medicine, The University of Texas Southwestern Medical School, Dallas, TX, USA Executive Editor, RheumNow.com Preface I am pleased to introduce this concise and comprehensive review of rheumatology to physicians preparing for the rheumatology board certification examination The goal was to provide the most up-to-date information, emphasizing high-yield facts, in an easy-to-read format, accented by tables, figures, and clinical imaging, without burdening the reader with extraneous details Moreover, each chapter was enhanced by a plethora of board-like, multiple-choice questions for the reader to practice and apply the knowledge gained by reviewing the various topics The contributing authors were selected because of their clinical and research expertise as well as their track record on being master educators The readers will recognize among the authors marquee names in academic rheumatology Beyond their involvement in every day clinical care, their research has revivified the specialty while themselves have become role models and nurtured the next generation of rheumatology leaders The intended audience for the book are in-training rheumatology fellows and practicing rheumatologists preparing for the certification and recertification examinations in rheumatology I strongly believe that interested physicians will find useful not only the content of this book but also its format; the use of the time-honored Socratic method of learning through questions and answers has served humanity well since its inception in Ancient Greece Petros Efthimiou New York University New York, NY ix Contents 1 Immunological Basis of Inflammatory Arthritides������������������������������    1 George D Kalliolias and

TNF receptor are also causes of monogenic inflammatory syndromes but are not specifically associated with the familial cold autoinflammatory syndrome (options D and E) Which of the following is a true statement about genetic testing? A Genetic testing is strictly regulated and under similar federal regulatory standards as other specialized laboratory tests B Direct-to-consumer testing is an adequate initial approach for patients with a suspected genetic disease C Single-gene testing is most helpful when the clinical presentation is vague and there are multiple candidate genes as potential causes for the disease D Next-generation sequencing has become obsolete since the Sanger sequencing technique became commercially available E Genetic testing is safe; therefore, obtaining an informed consent is not recommended Correct answer: A Genetic testing regulations are similar to other specialized laboratory tests to ensure the analytical and clinical validity, under the Clinical Laboratory Improvement Amendments (CLIA), a Centers for Medicare and Medicaid Services (CMS) program Direct-to-consumer genetic testing is not currently recommended as a diagnostic tool for genetic diseases (option B) In contrast to genetic panels where multiple genes are evaluated, single-gene testing is a much narrower strategy and would only be useful if there is only one or very few candidate genes (option C) Next-generation sequencing (NGS) technologies are widely used in commercial laboratories, while the Sanger technique is mostly used for confirmatory purposes (option D) Even though genetic testing is considered safe, the emotional impact and the possibility of identifying unexpected and unrelated genetic alterations, among other implications of genetic testing, need to be discussed with patients, and an informed consent should be obtained (option E) A 22-year-old woman presents to rheumatology clinic for evaluation of effort-­ related arthralgias She reports that since childhood she has been more flexible than her peers She can bend her thumbs backward to her wrists but cannot touch the floor with her palms when bending forward with her knees extended She also states that her skin bruises very easily and is thin Her mother died in her 20s while pregnant due to uterine rupture, and her father died in his 30s due to a spontaneous bowel perforation A diagnosis of vascular Ehlers-Danlos syndrome (EDS) is considered What is the most likely affected gene in this type of EDS? A B C D E FBN1 ADAMTS2 COL3A1 PLOD1 TNXB Correct answer: C 464 R Fernandez-Ruiz and P Efthimiou Vascular or type IV EDS is an AD disorder caused by a mutated COL3A1 gene, which codes for a collagen III pro-α1 chain Vascular EDS is a life-threatening disease due to spontaneous rupture of blood vessels and internal organs (intestines or uterus) FBN1 codes for fibrillin 1, the protein affected in Marfan syndrome (option A) ADAMTS2 is a procollagen peptidase associated with EDS VIIC or dermatosparaxis type, an AR characterized by prominent redundant and extremely fragile skin, hernias, and short stature (option B) PLOD1 codes for a lysyl hydroxylase and is associated with EDS type VI or kyphoscoliotic EDS type (option D) TNXB mutations (option E) are associated with classic-like EDS (AR disorder) and in less than 10% of patients with hypermobile EDS (AD inheritance) References Turanlı ET, Everest E, Balamir A, Aydın AK, Kasapỗopur ệ Role of genetics in pediatric rheumatology Turk Pediatri Ars 2017;52(3):113–21 Cornélis F. Genetics and clinical practice in rheumatology Joint Bone Spine 2003;70(6):458–64 Kirmani S.  Molecular genetic testing in endocrinology  – a practical guide Endocr Pract 2012;18(1):85–9 Domchek SM, Jameson J, Miesfeldt S. The practice of genetics in clinical medicine In: Kasper D, Fauci A, Hauser S, Longo D, Jameson J, Loscalzo J, editors Harrison’s principles of internal medicine 19th ed New  York, NY: McGraw-Hill; 2014 http://accessmedicine.mhmedical.com.ezproxy.med.nyu.edu/content.aspx?bookid=1130§ionid=79728285 Accessed 28 Jan 2019 Jameson J, Kopp P. Genes, the environment, and disease In: Kasper D, Fauci A, Hauser S, Longo D, Jameson J, Loscalzo J, editors Harrison’s principles of internal medicine 19th ed New York, NY: McGraw-Hill; 2014 http://accessmedicine.mhmedical.com.ezproxy.med.nyu edu/content.aspx?bookid=1130§ionid=79728075 Accessed 06 Feb 2019 Griffiths AJF, Miller JH, Suzuki DT, et al An introduction to genetic analysis In: Penetrance and expressivity 7th ed New York: W. H Freeman; 2000 Available from: https://www.ncbi nlm.nih.gov/books/NBK22090/ Federici L, Rittore-Domingo C, Koné-Paut I, Jorgensen C, Rodière M, Le Quellec A, Touitou I. A decision tree for genetic diagnosis of hereditary periodic fever in unselected patients Ann Rheum Dis 2006;65(11):1427–32 Caso F, Rigante D, Vitale A, Lucherini OM, Costa L, Atteno M, Compagnone A, Caso P, Frediani B, Galeazzi M, Punzi L, Cantarini L. Monogenic autoinflammatory syndromes: state of the art on genetic, clinical, and therapeutic issues Int J Rheumatol 2013;2013:513782 Colombi M, Dordoni C, Chiarelli N, Ritelli M.  Differential diagnosis and diagnostic flow chart of joint hypermobility syndrome/ehlers-danlos syndrome hypermobility type compared to other heritable connective tissue disorders Am J Med Genet C Semin Med Genet 2015;169C(1):6–22 10 Knob AL.  Principles of genetic testing and genetic counseling for renal clinicians Semin Nephrol 2010;30(4):431–7 11 Marsick R, Limwongse C, Kodish E. Genetic testing for renal diseases: medical and ethical considerations Am J Kidney Dis 1998;32(6):934–45 12 Institute of Medicine (US) Committee on Assessing Genetic Risks In: Andrews LB, Fullarton JE, Holtzman NA, et al., editors Assessing genetic risks: implications for health and social 19  Clinical Genetics in Rheumatology 465 policy Washington, DC: National Academies Press (US); 1994 2, Genetic testing and assessment Available from: https://www.ncbi.nlm.nih.gov/books/NBK236037/ 13 Finetti M, Omenetti A, Federici S, Caorsi R, Gattorno M. Chronic infantile neurological cutaneous and articular (CINCA) syndrome: a review Orphanet J Rare Dis 2016;11:167 14 Middleton A, Mendes Á, Benjamin CM, Howard HC.  Direct-to-consumer genetic testing: where and how does genetic counseling fit?
