  • Issues in CPPD Nomenclature and Classification
    Current Rheumatology Reports (2019) 21: 49 https://doi.org/10.1007/s11926-019-0847-4 CRYSTAL ARTHRITIS (L STAMP, SECTION EDITOR) Issues in CPPD Nomenclature and Classification Sara K. Tedeschi1 Published online: 25 July 2019 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Purpose of Review This paper covers confusion and challenges in the nomenclature of calcium pyrophosphate deposition disease. Clinicians, investigators, and patients are faced with a variety of terms that are used to describe CPPD and its phenotypes, and clarity is greatly needed to help advance research and patient care. Motivation for the upcoming development of CPPD classification criteria is reviewed. Recent Findings EULAR proposed recommended terminology for CPPD in 2011. International Classification of Diseases (ICD- 9 and ICD-10) billing codes identify definite or probable CPPD with variable accuracy depending on the clinical setting and comparator group. READ diagnostic codes have been employed to identify pseudogout in UK datasets but their accuracy has not been evaluated. CPPD classification criteria will provide a system for identifying a relatively homogenous group of patients to be included in clinical studies, enabling comparison of outcomes across studies. Summary CPPD nomenclature remains challenging for clinicians, investigators, and patients. A lay-friendly definition of CPPD, using easily accessible terminology, would be welcome. CPPD classification criteria are a necessary step in moving forward CPPD clinical research and may involve a range of clinical, laboratory, and imaging modalities. Keywords CPPD . Pseudogout . Acute CPP crystal arthritis . Classification criteria . Terminology . Nomenclature Introduction experts have noted that confusing nomenclature and a lack of classification criteria hinder our understanding of this com- Calcium pyrophosphate deposition (CPPD) disease represents mon arthritis [1, 4, 5].

The examination will be conducted in English. Faculty examiner: Professor Uwe Gbureck (University of Wuerzburg, Germany). Abstract Unosson, J. 2014. Physical Properties of Acidic Calcium Phosphate Cements. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1195. 73 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9081-2. The gold standard for bone replacement today, autologous bone, suffers from several disadvantages, such as the increased risk of infection due to the need for two surgeries. Degradable synthetic materials with properties similar to bone, such as calcium phosphate cements, are a promising alternative. Calcium phosphate cements are suited for a limited amount of applications and improving their physical properties could extend their use into areas previously not considered possible. For example, cement with increased strength could be used as load bearing support in selected applications. The focus of this thesis is, therefore, on how the physical properties of acidic calcium phosphate cements (brushite cements) are affected by compositional variations, with the ultimate aim of making it possible to formulate brushite cements with desired properties. In this thesis a method to measure the porosity of a cement was developed.

Vasant1 and M. J. Joshi2 1Government Engineering College, Rajkot, Gujarat, India 2Department of Physics, Saurashtra University, Rajkot, Gujarat, India Received: July 29, 2016 Abstract. Over the past few decades, a little word with big potential has been rapidly insinuating into the world’s consciousness, nano. The nano-scale structures permit the control of funda- mental properties of the materials without changing their chemical structure. Living organisms can create amazing ways to produce high performance materials that involve not only creation of implants, replacing bone tissues and organs, but also synthesis of biologically active materials promoting the fullest restoration of tissues and maintenance of necessary functions of an organ- ism. In the biomaterial research field, nowadays, a great attention is given to bone substitute materials, particularly, calcium phosphate based bio-materials play important roles in clinical applications as it possesses high bio-compatibility and excellent ability to undergo varying de- grees of resorbability. These materials show a positive interaction with living tissue that includes differentiation of immature cells towards bone cells and also have chemical bonding to the bone along the interface, thought to be triggered by the adsorption of bone growth-mediating proteins at the bio-materials surface. In the present review paper an attempt is made to cover properties and applications of various phosphate nano bio-materials like calcium phosphate, calcium polyphosphate, calcium pyrophosphate etc over a time span right from 1920 to 2016.

The calcium phosphate bioceramic was prepared by a wet precipitation method with acid and base reactions. The synthesized bioceramic was characterized in terms of X-ray diffraction (XRD), scanning electron microscopy (SEM/EDS), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), average crystallite size and refinement by the Rietveld method for the quantification of crystalline phases. The results indicated the formation of a biphasic calcium phosphate bioceramic comprising 67.6 % of β-calcium pyrophosphate (β-CPP) and 32.1 % of β-tricalcium phosphate (β-TCP). This biphasic calcium phosphate bioceramic synthesized using fish bone waste presented nanostructured nature with an average crystallite size of 69.58 nm, which is very promising for biomedical applications. Keywords: Calcium phosphate, biphasic bioceramic, fish bone waste, nanocrystallites. 1.
