THE IDENTIFICATION OF BOVINE TUBERCULOSIS IN ZOOARCHAEOLOGICAL ASSEMBLAGES VOLUME 1 (1 OF 2) J. E.

Working towards differential diagnostic criteria. Keywords: Palaeopathology, zooarchaeology, human osteoarchaeology, zoonosis, Iron Age, Viking Age, Iceland, Orkney, England ABSTRACT The study of human palaeopathology has developed considerably in the last three decades resulting in a structured and standardised framework of practice, based upon skeletal lesion patterning and differential diagnosis. By comparison, disarticulated zooarchaeological assemblages have precluded the observation of lesion distributions, resulting in a dearth of information regarding differential diagnosis and a lack of standard palaeopathological recording methods. Therefore, zoopalaeopathology has been restricted to the analysis of localised pathologies and ‘interesting specimens’. Under present circumstances, researchers can draw little confidence that the routine recording of palaeopathological lesions, their description or differential diagnosis will ever form a standard part of zooarchaeological analysis. This has impeded the understanding of animal disease in past society and, in particular, has restricted the study of systemic disease. This research tackles this by combining the disciplines of human palaeopathology and i zoopalaeopathology and focusing on zoonotic disease. The primary aim of this research was to investigate the skeletal manifestation of bTB in cattle, sheep/goat and pig to establish differential diagnostic criteria for its identification in zooarchaeological assemblages. Methods commonplace in human palaeopathology were adapted and applied to zoopalaeopathology, in addition to radiography and aDNA analysis. The results emphasise the difficulties but also the potential associated with the identification of systemic diseases in zooarchaeological assemblages. An approach to the classification of potentially infectious lesions is presented that enables the calculation of crude prevalence in disarticulated assemblages. In addition, the potential for aDNA analysis to shed further light on animal disease in the past is emphasised. Supervisors: Dr. J.M. Bond (Principal Supervisor) Dr. J.

Steinbach, M.D. INTRODUCTION The following curriculum guide comprises a list of subjects which are important to a thorough understanding of disorders that affect the musculoskeletal system. It does not include every musculoskeletal condition, yet it is comprehensive enough to fulfill three basic requirements: 1.to provide practicing radiologists with the fundamentals needed to be valuable consultants to orthopedic surgeons, rheumatologists, and other referring physicians, 2.to provide radiology residency program directors with a guide to subjects that should be covered in a four year teaching curriculum, and 3.to serve as a “study guide” for diagnostic radiology residents. To that end, much of the material has been divided into “basic” and “advanced” categories. Basic material includes fundamental information that radiology residents should be able to learn, while advanced material includes information that musculoskeletal radiologists might expect to master. It is acknowledged that this division is somewhat arbitrary. It is the authors’ hope that each user of this guide will gain an appreciation for the information that is needed for the successful practice of musculoskeletal radiology. I.

  • A Surgeon's Perspective on the Current Trends in Managing
    A Surgeon’s Perspective on the Current Trends in Managing Osteoarthritis David Dycus, DVM, MS, DACVS, CCRP Veterinary Orthopedic and Sports Medicine Group Annapolis Junction, MD Osteoarthritis (OA) is a chronic, progressive disease that affects both dogs and cats. It has been noted that up to 20% of adult dogs and 60% of adult cats have radiographic evidence of OA.1,2 Owners, themselves are becoming increasingly aware that bone and joint problems are and issue with their pet. Much of this increased awareness has come through the use of the Internet and social media. The overall outcome of osteoarthritis is centered on destruction of the articular cartilage and breakdown of the joint. Because of this OA must be thought of as a global disease process rather than an isolated disease entity. There is considerable cross talk among the tissues that make up a joint. For this reason the joint must be thought of as an organ and the final pathway of OA is organ failure of the joint. OA primarily affects diarthrodial joints. A diarthrodial joint is composed of the joint capsule, synovial lining, articular cartilage, and the surrounding muscles, ligaments, tendons, and bone. The joint capsule is composed of two layers: the outer fibrous layer and the inner subsynovial layer. Both layers have a rich blood and nerve supply. One explanation of pain associated with OA is distention of the joint capsule due to joint effusion. The synovial lining covers ever structure in the joint except for the cartilage/menisci. It provides a low friction lining and is responsible for the production of synovial fluid.

    eoplasia is an abnormal, uncontrolled, pro- gressive proliferation of cells in any tissue CHAPTER or organ. Classification of neoplasms is N based upon general tissue origin (epithelial vs. mesenchymal), specific cell lineage and whether the neoplasm is benign (-oma) or malignant (sarcoma or carcinoma). Classification of some neoplasms as benign or malignant may require knowledge of the biological behavior of the neoplasm. 25 The majority of the veterinary medical literature has reported the incidence, gross appearance and micro- scopic characteristics of neoplasms of domesticated birds, especially poultry.20,22,23,101,109 Furthermore, the study of retroviral-induced neoplasia in poultry has advanced medical knowledge of retroviral molecular biology, as well as that of neoplasm development, growth and metastasis.91,101 Similar information con- ONCOLOGY cerning neoplasms of captive and free-ranging birds is almost nonexistent. One ultrastructural survey of various budgerigar neoplasms failed to disclose retroviral particles, but sampling errors are a known complication of such studies.52 More recently, papil- lomaviruses have been demonstrated as the etiologic agents of cutaneous papillomas in African Grey Par- rots, Chaffinches and Bramblings.73,87,94,96 Kenneth S.

The overall incidence of neoplasia approxi- mated 3.8% in all avian submissions.108 Compared to free-ranging birds, neoplasia is re- ported more frequently in companion and aviary birds because such birds are observed closely for abnormalities, have a longer life span and may have a genetic predisposition to neoplasia through in- breeding.

  • Reptiles – Bones – Clinical Considerations
    REPTILES – BONES – CLINICAL CONSIDERATIONS Douglas Mader, MS, DVM, Dipl ABVP (C/F, R/A), Dipl ECZM (Herpetology) Marathon Veterinary Hospital, 5001 Overseas Hwy, Marathon, FL 33050 USA ABSTRACT Introduction Conditions affecting the bones of reptiles are commonplace. Whether it is iatrogenic or traumatic, or a combination of both, orthopedic pathology is a frequent reason for a visit to the veterinarian. Understanding the genesis of the pathology helps manage the condition and ensure rapid and complete resolution. Metabolic Bone Diseases Metabolic bone diseases (MBD) are common in captive reptiles. MBD is not actually a single disease entity, but rather a term used to describe a collection of medical disorders affecting the integrity and function of bones. There are many different metabolic bone diseases that affect both animals and people. Historically, in the reptilian literature, any pathology affecting the bones of reptiles has been haphazardly called MBD. It is imperative that the old, incorrect nomenclature be dropped from the literature and vocabulary of reptile practitioners. The following is a brief overview of several well documented MBD's in reptiles. Nutritional Secondary Hyperparathyroidism (NSHP) Metabolic bone disease of nutritional origin (nMBD), which is the most common type of MBD that affects captive herpetofauna, is a consequence of dietary and husbandry mismanagement. Several factors combine to cause a prolonged deficiency of calcium and/or vitamin D, an imbalance of the calcium to phosphorus ratio in the diet, lack of exposure to direct, unfiltered natural sunlight or combinations thereof. Nutritional Secondary Hyperparathyroidism (NSHP) is the technical name for the MBD of nutritional origin that is commonly seen in captive herpetofauna.

    CHAPTER 7 ORTHOPAEDIC RADIOGRAPHY DARRYL BIERY General Principles Radiographic Alterations Density Size, Shape, and Contour Lesion Margin Periosteal Reaction Location and Distribution Soft Tissues Lesion Characterization Fractures Joints Image Modalities for Assessment of Musculoskeletal Disease GENERAL PRINCIPLES Radiography is one of the most useful diagnostic tools in veterinary medicine for the detection and diagnosis of suspected musculoskeletal disease. Radiographs permit localization and characterization of a lesion, which together with the animal's history, clinical signs, and physical and laboratory findings are used to achieve a tentative or specific diagnosis. Technically excellent radiographs must be made. Fortunately the bony structures provide excellent subject contrast for imaging normal and abnormal structures. Certain body parts, such as the skull and spine, may require greater radiographic detail for examination. A variety of fine-detail screens or film techniques exist for these purposes. A comprehensive description of radiographic and subject factors that affect radiographic quality is beyond the scope of this chapter; the reader is referred to other excellent texts for a discussion of this subject (2l 28,33) Failure to perceive a lesion is commonly related to radiographs that are unsatisfactory as a result of underexposure, overexposure, improper positioning of a body part, or an insufficient number of radiographic views. With technically excellent radiographs, most skeletal lesions will be detected. It should be remembered that since a radiograph is only a two- dimensional image, a minimum of two views, preferably perpendicular to each other, is usually necessary for examination of a part (Fig. 7-1). Occasionally, a lesion is seen on only one of two or more radiographic views.

  • Malignant Or Benign? Diagnosis from Radiographic Features of Bone Lesions
    Vet Times The website for the veterinary profession https://www.vettimes.co.uk Malignant or benign? Diagnosis from radiographic features of bone lesions Author : NATALIE WEBSTER Categories : Vets Date : March 3, 2008 NATALIE WEBSTER discusses x-ray diagnosis of non-aggressive and aggressive bone lesions in small animals DECIDING whether a bony lesion seen on a radiograph is malignant or benign is a challenge frequently faced by veterinarians. Bone responds to injury or a pathological process with osteolysis, osteoproduction or a combination of the two. In veterinary medicine, very few processes are easily categorised as black or white, and bone lesions are no exception. Non-aggressive and aggressive lesions A spectrum of bony changes may be seen, ranging from severely aggressive to intermediate, lowgrade malignancy (non-aggressive and aggressive features) to non-aggressive. Often a lesion will have both aggressive and non-aggressive characteristics representing different stages of the disease process. Aggressive bone lesions are characterised by rapid growth with minimal or absent host response to confine and wall-off the lesion. Aggressive lesions are usually malignant - for example, due to a primary bone neoplasia - but may also be due to an infectious process such as fulminant osteomyelitis. Non-aggressive lesions are slow-growing and relatively benign. They are characterised by a smooth, non-active host response with clear demarcation of the lesion as seen with a healing 1 / 39 fracture callus. The distinction between aggressive and non-aggressive lesions is important because of the potentially life-threatening consequences of their underlying causes. The prognosis and treatment vary widely depending on whether the lesion is thought to be aggressive or non- aggressive.
