Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints. It affects around 1-3% of the population and is more common in women. Symptoms include joint stiffness, pain, swelling, and loss of function. Left untreated, it can cause permanent joint damage and disability. Treatment involves medications to reduce inflammation and prevent joint damage, including NSAIDs, steroids, DMARDs such as methotrexate, and biologic medications that target specific immune system proteins. The goals of treatment are to relieve symptoms, prevent disability, and induce remission if possible through a combination of medications, physical therapy, education, and lifestyle changes.

rheumatoid arthritis is a chronic, systemic, inflammatory autoimmune disorder that primarily affects the joints, but may also manifest with extraarticular features.
For information about the disease and learn more, you can obtain basic informations from the following file.
Rheumatoid arthritis, or RA, is an autoimmune and inflammatory disease, which means that your immune system attacks healthy cells in your body by mistake, causing inflammation (painful swelling) in the affected parts of the body. RA mainly attacks the joints, usually many joints at once.
Rheumatoid arthritis (RA) is a chronic, progressive inflammatory disorder of unknown etiology characterized by polyarticular symmetric joint involvement and systemic manifestations.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent
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

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

2. Introduction
Rheumatoid arthritis (RA) is an autoimmune disease that results
in a chronic, systemic inflammatory disorder, primarily causing
non suppurative inflammation of the synovial joints
Multisystem disease affecting 1-3% of population
Female: male 3:1
third to sixth decades.
Morning joint stiffness > 1 hour and easing with physical activity
is characteristic.
Small joints of hand and feet are typically involved.
3.
4. Who is at Risk for RA?
Women > men
Age –30 – 60 yrs
Genetic component-HLA-
drw4/HLA-DR1
Cigarette smoking
Infections- mycoplasma, clostridium ,
EB virus
Occupational exposure to certain dusts
such as silica, wood, or asbestos
10. Relative incidence of joint
involvement in RA
MCP and PIP joints of hands & MTP of feet 90%
Knees, ankles & wrists- 80%
Shoulders- 60%
Elbows- 50%
TM, Acromio - clavicular & SC joints- 30%
11. Joints involved in RA
Don’t forget the cervical spine!!
Instability at cervical spine can lead to
impingement of the spinal cord.
Thoracolumbar, sacroiliac, and distal
interphalangeal joints (DIP)of the hand are
NOT involved.
12. Symptoms of RA?
Hallmark symptoms of swollen, painful, and stiff joints and
muscles.
The muscle and joint stiffness is usually worst in the
morning or after extended periods of inactivity.
Patients may also experience symptoms such as fatigue, low-
grade fever, lack of energy, and loss of appetite.
17. Extra-articular manifestations
Present in 30-40%
May occur prior to arthritis
Patients that are more likely to get are:
High titres of RF/ anti-CCP
HLA DR4+
Male
Early onset disability
History of smoking
20. Remission, Relapse, and Flares
When a person with rheumatoid arthritis has symptoms
including joint inflammation and pain, this is called a flare,
may last from weeks to months.
This can alternate with periods of remission, when
symptoms are minimal to nonexistent. Periods of remission
can last weeks, months, or even years.
After a period of remission, if the symptoms return this is
called a relapse.
It is common for RA patients to have periods of flares,
remissions, and relapses, and the course of the illness varies
with each patient.
24. Rheumatoid Factor (RF)
Antibodies that recognize Fc portion of IgG
Can be IgM , IgG , IgA
85% of patients with RA over the first 2 years become RF+
• A negative RF may be repeated 4-6 monthly for the first two year of
disease, since some patients may take 18-24 months to become
seropositive.
• PROGNISTIC VALUE- Patients with high titres of RF, in general,
tend to have POOR PROGNOSIS, MORE EXTRA ARTICULAR
MANIFESTATION.
25. Causes of positive test for RF
Rheumatoid arthritis
Sjogrens syndrome
Vasculitis such as polyarteritis nodosa
Sarcoidosis
Systemic lupus erythematosus
Cryoglobulinemia
Chronic liver disease
Infections- tuberculosis , bacterial endocarditis, infectious
mononucleosis, leprosy, syphilis, leishmaniasis.
Malignancies
Old age(5% women aged above 60)
26. Anti-CCP
IgG against synovial membrane peptides
damaged via inflammation
Sensitivity (65%) & Specificity (95%)
Both diagnostic & prognostic value
Predictive of Erosive Disease
Disease severity
Radiologic progression
Poor functional outcomes
27. Radiographic Features
Peri-articular osteopenia
Uniform symmetric joint space narrowing
Marginal subchondral erosions
Joint Subluxations
Joint destruction
Collapse
Ultrasound detects early soft tissue lesions.
MRI has greatest sensitivity to detect
synovitis and marrow changes.
33. Goals of management
Focused on relieving pain
Preventing damage/disability
Patient education about the disease
Physical Therapy for stretching and range of motion
exercises
Occupational Therapy for splints and adaptive
devices
Treatment should be started early and should be
individualised .
EARLY AGGRESSIVE TREATEMNT
34. Education and Counseling
Biofeedback and cognitive behavioral therapy
Reduce pain and disability and improve self-esteem.
35. Cholesterol
People with rheumatoid arthritis have a higher risk of
developing CAD.
High blood cholesterol is one risk factor for coronary disease
that can respond to changes in diet
36. Smoking and Alcohol
Quit completely.
Moderate alcohol consumption is not harmful to
rheumatoid arthritis, although it may increase the risk of
liver damage from some drugs such as Methotrexate.
37. Treatment modalities for RA
NSAIDS
Steroids
DMARDs
Immunosuppressive therapy
Biological therapies
Surgery
38. NSAIDS
Non-Steroidal anti-inflammatories (NSAIDS)
/ Coxibs for symptom control
1) Reduce pain and swelling by inhibiting COX
2) Do not alter course of the disease.
3) Chronic use should be minimised.
4) Most common side effect related to GI tract.
39. Corticosteroids in RA
Corticosteroids , both systemic and intra-articular are
important adjuncts in management of RA.
Indications for systemic steroids are:-
1. For treatment of rheumatoid flares.
2. For extra-articular RA like rheumatoid vasculitis and
interstitial lung disease.
3. As bridge therapy for 6-8 weeks before the action of
DMARDs begin.
4. Maintainence dose of 10mg or less of predinisolone
alternate dose in patients with active RA.
5. Sometimes in pregnancy when other DMARDs cannot be
used.
40. Disease Modifying Anti-rheumatic Agents
Drugs that actually alter the disease course .
Should be used as soon as diagnosis is made.
Appearance of benefit delayed for weeks to
months.
Induction of true remission is unusual .
41. DMARDs
Commonly used Less commonly used
Methotrexate Chloroquine
Hydroxychloroquine Gold(parenteral &oral)
Sulphasalazine CyclosporineA
Leflunomide D-penicillamine/bucillamine
Minocycline/Doxycycline

44. When to start DMARDs?
DMARDs are indicated in all patients with RA.
45. How to select DMARDs?
There are no strict guidelines about which DMARDs
to start first in an individual.
Methotrexate has rapid onset of action than other
DMARD.
Taking in account patient tolerance, cost
considerations and ease of once weekly oral
administration METHOTREXATE is the DMARD
of choice, most widely prescribed in the world.
46. Should DMARDs be used singly or
in combination?
Since single DMARD therapy (in conjunction with NSAIDS) is often
only modestly effective , combination therapy has an inherent appeal.
DMARD combination is specially effective if they include
methotrexate as an anchor drug.
47. Limitations of conventional DMARDs
1) The onset of action takes several months.
2) The remission induced in many cases is partial.
3) There may be substantial toxicity which
requires careful monitoring.
4) DMARDs have a tendency to lose effectiveness
with time-(slip out).
These drawbacks have made researchers look
for alternative treatment strategies for RA- The
Biologic Response Modifiers.
48. Immunosuppresive therapy

.
.
49. BIOLOGICS IN RA
Cytokines such as TNF-α ,IL-1,IL-10 etc. are key
mediators of immune function in RA and have
been major targets of therapeutic manipulations in
RA.
Of the various cytokines, TNF-α has attaracted
maximum attention.
Various biologicals approved in RA are:-
1) Anti TNF agents : Infliximab Etanercept Adalimumab
2) IL-1 receptor antagonist : Anakinra
3) IL-6 receptor antagonist : Tocilizumab
4) Anti CD20 antibody : Rituximab
5) T cell costimulatory inhibitor : Abatacept

52. JAK inhibitors
A new subcategory of DMARDs known as “JAK
inhibitors” block the Janus kinase, or JAK,
pathways, which are involved in the body’s
immune response.
Tofacitinib belongs to this class.
Unlike biologics, it can be taken by mouth.
53. How to monitor Tt in RA?
Disease activity is assesed by several parameters…
duration of morning stiffness,tender joint count,swollen
joint count,observer global assessment,patient global
assessment,visual analogue scale for pain,health
assessment questionnaire,ESR,NSAID pill count,DAS
score etc..
• Patient on MTX,SSZ or leflunamide show clinical
improvement in 6-8 wks.
• Patient should be observed for 6 months before
declaring a DMARD ineffective.
54. How long should Tt. be continued?
Once remission is achieved , maintenance dose for long period is
recommended.
Relapse occurs in 3-5 months (1-2 months in case of MTX) if drug is
discontinued in most instances.
DMARDs are discontinued by patients because of toxicity or
secondary failure(common after 1-2 yrs) and such patients might
have to shift over different DMARDs over 5-10 yrs.
Disease flare may require escalation of DMARD dose with short
course of steroids.
55. Flares
In people who are already taking methotrexate or
oral steroids-increasing the doses
steroids injection.
56. Surgical Approaches
Synovectomy not recommended - relief is only
transient.
exception is synovectomy of the wrist, if intense
synovitis is persistent despite medical treatment over
6 to 12 months(can lead to extensor tendon sheath
rupture)
Total joint arthroplasties
Release of nerve entrapments (e.g., carpal tunnel
syndrome), arthroscopic procedures, and,
occasionally, removal of a symptomatic rheumatoid
nodule.
