This document discusses diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier's disease. It most commonly affects the elderly, especially between the ages of 60-70. Key features include bone proliferation at sites of tendon and ligament insertion, especially along the spine. Pathology involves calcification and ossification of spinal ligaments. Extra spinal features can include enthesopathy of bones like the iliac crest and greater trochanters. DISH is characterized by flowing ossification along at least four contiguous vertebrae that preserves disc spaces and can result in ankylosis.
Madelung deformity is an abnormality of the palmar ulnar part of the distal radial physis in which progressive ulnar and volar tilt develops at the distal radial articular surface, with dorsal subluxation of the distal ulna.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

New Drug Discovery and Development .....NEHA GUPTA
The "New Drug Discovery and Development" process involves the identification, design, testing, and manufacturing of novel pharmaceutical compounds with the aim of introducing new and improved treatments for various medical conditions. This comprehensive endeavor encompasses various stages, including target identification, preclinical studies, clinical trials, regulatory approval, and post-market surveillance. It involves multidisciplinary collaboration among scientists, researchers, clinicians, regulatory experts, and pharmaceutical companies to bring innovative therapies to market and address unmet medical needs.
2. DISH
• Diffuse idiopathic skeletal hyperostosis
or Forestier disease is a common condition
characterized by bone proliferation at sites of
tendinous and ligamentous insertion.
• Epidemiology
• It most commonly affects the elderly
(especially 6th to 7th decades).
• Its estimated frequency in the elderly is at ~ 5-
15%
3. Pathology
• Pathologic features of spinal DISH include:
• Focal and diffuse calcification and ossification of the
anterior longitudinal ligament,
• Paraspinal connective tissue and annulus fibrosis,
• Degeneration in the peripheral annulus fibrosis fibers,
• Anterolateral extensions of fibrous tissue,
• Hypervascularity,
• Chronic inflammatory cellular infiltration,
• Periosteal new bone formation on the anterior surface
of the vertebral bodies.
4. Associations
• Ossification of the posterior longitudinal
ligament (OPLL)
• Hyperglycaemia.
• Approximately one-third of patients test
positive for human leukocyte antigen
(HLA)B27.
5. Spinal features:
• Florid, flowing ossification along the anterior
or right anterolateral aspects of at
least four contiguous vertebrae.
• Disc spaces are usually well preserved.
• Ankylosis is more commonly seen in the
thoracic than in the cervical or lumbar spine.
Frequently incomplete can have interdigitating
areas of protruding disk material in the
flowing ossifications.
6. Extra spinal features
• Enthesopathy of:
• iliac crest,
• ischial tuberosities,
• greater trochanters,
• spur formation in the appendicular skeleton
(olecranon, calcaneum).
14. Ankylosing Spondylitis – Radiological
features
• early spondylitis is characterized by small erosions at
the corners of vertebral bodies with reactive sclerosis
• squaring of the vertebral body
• diffuse syndesmophyitic ankylosis can give a "bamboo
spine" appearance
• interspinous ligament calcification can give a "dagger
spine" appearance
• ossification of spinal ligaments, joints and discs.
• Psuedoarthroses may form at fracture sites.
• enthesophyte formation from enthesopathy.
• Romanus lesions of the spine - shiny corner sign.
17. Fluorosis - radiological features:
• The earliest radiological findings appear within six
mouths of continuous exposure to high intakes of
fluoride and include periosteal and endosteal
reactions, coarse axial trabcculations and osteopenia in
the metaphyseal regions, sclerosis, and modelling
abnormalities of the epiphyses, carpal and other bones
of the hand, more particularly observed in growing
children.
• The incidence of spinal osteoporosis is significantly low
and of osteomalacia and secondary hyperparathyroid
bone disease significantly higher in women residing in
endemic fluorosis villages.
20. Paget’s disease – Spine Radiology
• Spine: cortical thickening encasing the vertebral
margins, which gives rise to the picture frame sign on
radiographs in mixed phase disease.
• On lateral radiographs flattening or squaring of the
normal concavity of the anterior margin of the
vertebral body also adds to the rectangular
appearance.
• The osteoblastic activity is seen along all four margins
of the vertebral body cortices.
• The vertical trabecular thickening pattern in Paget
disease is coarser than the more delicate pattern seen
in hemangiomas with which it can be confused.
21. Paget’s disease – Radiology Pelvis
• Paget disease of the pelvis usually manifests
with cortical thickening and sclerosis of the
iliopectineal and ischiopubic lines. These
findings are often asymmetric and for some
reason, may be more commonly seen on the
right side. Enlargement of the pubic rami and
ischium are also often seen.
