This document discusses rheumatic fever, which is an inflammatory disease that can develop after a streptococcal throat infection. It causes damage to the heart valves and joints. Major symptoms include heart inflammation, migratory arthritis, and abnormal movements. Diagnosis is based on the Jones criteria of symptoms and evidence of prior strep infection. Treatment involves antibiotics to kill the bacteria as well as medications for symptoms. Long-term prevention of recurrence involves ongoing antibiotics.

Rheumatic fever (acute rheumatic fever) is a disease that can affect the heart, joints, brain, and skin.
Rheumatic fever can develop if strep throat and scarlet fever infections are not treated properly.
Early diagnosis of these infections and treatment with antibiotics is key to preventing rheumatic fever.
Acute rheumatic fever (ARF), an auto-immune response to group A streptococcus (GAS)
infection of the upper respiratory tract, may result in carditis or inflammation of the mitral
and/or aortic valves. When the inflammation leads to permanent damage of the valves the
individual has rheumatic heart disease (RHD). Recurrences of rheumatic fever are likely in the
absence of preventative measures and may cause further cardiac valve and muscle damage,
leading to heart failure, strokes and premature death . Bacterial endocarditis is also a
complication.
Acute rheumatic fever usually affects children (most commonly between 5 and
15 years) or young adults, and has become very rare in Western Europe and North America
However, it remains endemic in parts of Asia, Africa and South America, with an annual
incidence in some countries of > 100 per 100 000, and is the most common cause of acquired
heart disease in childhood and adolescence.
The burden of ARF in industrialised countries
declined dramatically during the 20th century, due mainly to reduced transmission of GAS
related to improved living conditions and increased hygiene standards along with better access
to appropriate health services and increased access to penicillin-based medications. In most
affluent populations, including much of Australia, ARF is now rare, and RHD occurs
predominantly in the elderly.

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

Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
