Immunohistochemical localization of calcitonin gene-related peptide and substance P in the rat knee cartilage at birth.

Abstract: Substance P (SP) and calcitonin gene-related peptide (CGRP) have been found in the perichondrium and within the cartilage canals. It is still unknown whether they exert a direct effect on chondrocytes during joint development. We processed 28 knees of newborn Wistar rats in 7 different fashions to perform histology and immunohistochemistry studies. Positive immunoreactivity against CGRP and SP was found in the inner aspect of the perichondrium in a close contact with chondrocytes. The presence of CGRP and SP indicates the presence of nerves fibers, and precedes the development of cartilage canals. Nerve fibers may play a role in the development of synovial joints before and during the presence of cartilage canals. The presence of CGRP and SP in the cartilage at birth may be involved in the early postnatal maturation of synovial joints. It remains to be determined whether autonomic innervation is later involved in age-related degenerative joint disease.

Top orthopedic sports medicine procedures

Abstract: Orthopedic sports medicine is a subspecialty of Orthopedics that focuses on managing pathological conditions of the musculoskeletal system arising from sports practice. When dealing with athletes, timing is the most difficult issue to face. Typically, athletes aim to return to play as soon as possible and at the pre-injury level. This means that management should be optimized to combine the need for prompt return to sport and to the biologic healing time of the musculo-skeletal. This poses a great challenge to sport medicine surgeons, who need to follow with attention to the latest scientific evidence to offer their patients the best available treatment options. We briefly review the most commonly performed orthopedic sports medicine procedures, outlining the presently available scientific evidence on their indications and outcomes.

Histopathological scores for tissue-engineered, repaired and degenerated tendon: a systematic review of the literature.

Abstract: Purpose: This systematic review analyzes histological scoring systems for degenerative tendon-enthesis changes, ex vivo tendon-enthesis repair and tissue-engineered tendon-enthesis repair. A secondary aim is to establish the validity and applicability of these scores to find a comprehensive and validated histological scoring system for the evaluation of tendon-enthesis tissue. Methods: We performed a systematic review of the literature by analyzing the following databases: PubMed, Embase, Medline, CINAHL, and Cochrane. The methodology of the study was developed according to the PRISMA guidelines. Results: Twenty-seven articles, describing a total of 9 scores for tendinopathy, 6 scores for tendon ruptures, and 12 scores for tendon regeneration were included. For enthesis changes, 4 studies describe a total of 3 scores for enthesopathy and 1 scores for enthesis regeneration. The Movin score and its modifications seem be the more comprehensive to assess the degenerative changes; the Soslowsky score, the Watkins score, the Novel scoring system and the Burssens score seem be the more comprehensive to assess tendon repair process. Only the Matthys score assesses the histological changes in enthesopathies, and the modified Watkins score has been well applied to assess enthesis repair. Conclusion: The assessment of tendon-enthesis structure can be performed with several histological scoring systems previously published in literature. However, no studies have been performed to validate these score in research settings. Further experimental and clinical studies should be developed to provide a comprehensive and validated scoring system for the histological assessment of tendon-enthesis repair.

Growth factors and tendon healing.

Abstract: Recent attention has focused on the biological pathways by which tendons heal leading to the identification of some growth factors (GFs) with involvement in this process. No studies have been published on the time course of the various GFs during the tendon healing process in vivo in humans. We review what is known about these GFs and their role in tendon healing.

Pilot experimental study on amniotic epithelial mesenchymal cell transplantation in natural occurring tendinopathy in horses. Ultrasonographic and histological comparison.

Abstract: Background amnion-derived stem cells are considered a promising alternative source for tendon tissue regeneration. Purpose aims of this paper were to illustrate the ultrasound and histological outcomes following the treatment of acute and chronic superficial digital flexor tendon spontaneous lesions in horses with ovine amniotic epithelial cells xenotransplantation. Methods six adult horses suffering from unilateral acute (4 cases) and chronic (2 cases) tendinopathy (clinical and ultrasound diagnosis) were enrolled. At baseline, ovine amniotic epithelial cells were grafted, in sterile conditions and under ultra-sound control, into the most damaged area. Ultra-sound controls were performed at 30, 60, 90, 120, 150 and 180 days after cells implantation; after horse euthanasia (180 days) tendon samples were collected and submitted to histological examination (cellularity, extracellular matrix fiber organization, blood vessels). Results at baseline, in the acute cases, the ultra-sound exam showed a focal, dis-homogeneous, hypo-echoic area into the superficial digital flexor tendon, with loss of the normal fibrillar pattern, while in the chronic cases the damaged tendon area appeared thickened and completely hyper-echoic. At the final follow-up tendon echotexture was more regular, the cross-sectional area similar to the contra-lateral limb, and the collagen fibers were oriented in parallel to the longitudinal axis of the tendon both in the acute and chronic cases, suggesting a positive healing response. These findings were supported by the histological analyses which showed an almost complete restoration of normal tendon architecture with an optimal alignment of tendon fibers. Conclusions the present pilot study supports the hypothesis that amniotic epithelial cells are provided of an excellent healing potential and shows a very good correlation between the ultrasound findings and the histologic features.

I and i

Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

Standards of Medical Care in Diabetes

Abstract: XI. STRATEGIES FOR IMPROVING DIABETES CARE D iabetes is a chronic illness that requires continuing medical care and patient self-management education to prevent acute complications and to reduce the risk of long-term complications. Diabetes care is complex and requires that many issues, beyond glycemic control, be addressed. A large body of evidence exists that supports a range of interventions to improve diabetes outcomes. These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care. While individual preferences, comorbidities, and other patient factors may require modification of goals, targets that are desirable for most patients with diabetes are provided. These standards are not intended to preclude more extensive evaluation and management of the patient by other specialists as needed. For more detailed information, refer to Bode (Ed.): Medical Management of Type 1 Diabetes (1), Burant (Ed): Medical Management of Type 2 Diabetes (2), and Klingensmith (Ed): Intensive Diabetes Management (3). The recommendations included are diagnostic and therapeutic actions that are known or believed to favorably affect health outcomes of patients with diabetes. A grading system (Table 1), developed by the American Diabetes Association (ADA) and modeled after existing methods, was utilized to clarify and codify the evidence that forms the basis for the recommendations. The level of evidence that supports each recommendation is listed after each recommendation using the letters A, B, C, or E.

Harrison's Principles of Internal Medicine

Abstract: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many
