Rheumatoid arthritis, systemic lupus erythematosus, and systemic scleroderma can all involve the joints, muscles, and bones but have distinct patterns of involvement. Rheumatoid arthritis predominantly affects the small joints of the hands and feet symmetrically, leading to erosions, deformities, and joint destruction. Systemic lupus erythematosus usually causes non-deforming arthritis or arthralgia that can be migratory or asymmetric, with normal joint spaces but subchondral sclerosis and osteopenia. Systemic scleroderma is characterized by soft tissue calcification, acro-osteolysis of the distal phalanges, and flexion contractures resulting from
Student's elbow, or 'Olecranon Bursitis' is a condition where a small sack of tissue over the tip of your elbow becomes inflamed and swollen. The pointy bit of bone at the end of your elbow is called the 'olecranon' and the small sack which sits between the bone and the skin is called a 'bursa'.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
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
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Differential diagnosis of musculoskeletal involvement in rheumatoid arthritis, sle, and systemic scleroderma
1. Differential diagnosis of joint, muscle and bone
involvement in rheumatoid arthritis, systemic lupus
erythematous, and systemic scleroderma
2. Overview
Rheumatoid arthritis (RA) is an autoimmune disease of unknown etiology that affects many organs but more
predominantly synovial tissue and joints, manifesting with symmetric, inflammatory, peripheral polyarthritis.
It typically leads to deformity and destruction of joints through the erosion of cartilage and bone.
Arthritis symptoms typically first develop in the hands and wrists in a symmetric, proximal distribution. Feet
and large joints may also be involved.
Epidemiology: overall world prevalence is approx. 1%. With a female to male ratio of 3:1, ages 30-50
Pathogenesis: IgM autoantibodies to FC portion of IgG, forming immune complexes which deposit in joints
resulting in inflammation.
Clinical features:
Musculoskeletal pain which decreases with activity, tenderness, swelling, subcutaneous nodules, morning
stiffness >30minutes
Polyarthritis of MCP and PIP joints, but it commonly does NOT involve DIP joints. Wrists, elbows, ankles, knees
also commonly are involved.
Persistent symmetric polyarthritis (synovitis) of hands and feet (hallmark feature)
affected joints show inflammation with swelling, tenderness, warmth, and decreased range of motion (ROM).
Joint and tendon destruction may lead to deformities such as ulnar deviation, boutonniere and swan neck
deformities, hammertoes, and occasionally, joint ankylosis.
Other commonly observed manifestations: tenosynovitis, periarticular osteoporosis, carpal tunnel syndrome,
generalized osteoporosis
3. The radiographic hallmarks of rheumatoid
arthritis are:
erosions; important early finding, frequently in the radial side of the metacarpophalangeal
(MCP) joints
Soft tissue swelling: fusiform and periarticular; represents a combination of joint effusion,
edema, and tenosynovitis. This can be an early/only radiological finding.
Osteoporosis; initially juxta-articular and later generalized
Symmetrical or concentric joint space narrowing
Hands and Wrists Involvement
The disease tends to affect the proximal joints in a bilateral, symmetrical distribution.
PIP and MCP joints (specially 2nd and 3rd MCP)
Ulnar styloid
Triquetrum
DIP joints are spared
4. Late changes include:
Subchondral cyst
Subluxation causing: a) ulnar deviation of MCP joints, b) boutonniere and swan neck deformities
Hitchhiker’s thumb deformity
Carpal instability, ulnar translocation
Anykylosis
Scallop sign; erosion of ulnar aspect of distal radius
Feet
similar to the hands, there is a predilection for the PIP and MTP joints (specially 4th and 5th MTP)
Involvement of subtalar joint
Hammertoe deformity
Hallux valgus
5. Knee
Joint effusion
Typically involves lateral or non-weight bearing portion of the joint
Loss of joint space involving all three compartments
Prepatellar bursitis
Hip
Concentric loss of joint space
Acetabular protrusio
Shoulder
Erosion of distal clavicle, marginal erosions of humeral head, reduction in acromiohumeral
distance “high-riding shoulder” due to subacromial-subdeltoid bursitis
Spine
Cervical spine is more frequently involved in RA, thoracic and lumbar involvement is rare.
Findings include: erosions, atlantoaxial subluxation
6. Diagnosis of RA is based on the diagnostic criteria developed by American college of
rheumatology 2010. A total score of 6+ is classified as rheumatoid arthritis.
Investigations include:
CPR and ESR (elevated)
Serological markers: RF, anti-CCP, ACPA
Radiography: erosions, swelling of soft tissue, joint narrowing, juxtoarticular
osteoporosis
Ultrasound: assess synovial proliferation and inflammation of superficial
joints, tenosynovitis, bursitis
MRI: sensitive to early and subtle features of RA
16. SLE
Systemic lupus erythematosus (SLE) is a chronic, multisystem autoimmune inflammatory
disease that can affect any part of the body. SLE is a disease of unknown aetiology with a
variety of presenting features and manifestations. Characterized by microvascular
inflammation with the generation of numerous autoantibodies, particularly antinuclear
antibodies (ANA)
The majority of the pathology in SLE is related to deposits of immune complexes in
various organs, which triggers complement and other mediators of inflammation
Diagnosis can be difficult because lupus mimics many other diseases; it requires clinical
and serologic criteria.
Epidemiology
Female:Male 10:1
Peak in 20s-30s
More common in black patients
17. Musculoskeletal manifestations: joint pain, with small joints of the hand and wrist usually
affected. Arthralgia, arthritis, osteonecrosis (avascular necrosis of bone), and myopathy are
the principal manifestations.
Arthralgia, myalgia, and frank arthritis may involve the small joints of the hands, wrists, and
knees
In contrast to rheumatoid arthritis, SLE arthritis or arthralgia may be asymmetrical, with
pain that is disproportionate to swelling. Also the arthritis and arthralgia of SLE tend to be
migratory, morning stiffness is usually measured in minutes. The arthritis of SLE is generally
considered to be non-deforming.
Involves joint space loss, subchondral sclerosis, osteophyte, and ulnar deviation of the
phalanges without erosions such as in RA
Diagnosis is based on SLICC Classification Criteria 2012. Requirements: >4 of the following
criteria (at least 1 clinical and 1 laboratory) OR biopsy proven lupus nephritis with positive ANA
or Anti-dsDNA
18. Clinical criteria
Malar rash bullous lupus, photosensitivity
Discoid rash, hypertrophic lupus
Oral ulcers or nasal ulcers
Non-scarring alopecia
Synovitis
Serositis
Nephritis
Cerebritis, myelitis, neuropathy
Hemolytic anemia
leukopenia or lymphopenia
Thrombocytopenia
Immunological criteria
ANA
Anti-dsDNA
Anti-Sm
Antiphospholipid antibody
Low complement C3, low C4
Direct Coombs' test in the absence of haemolytic anaemia
19. Musculoskeletal manifestations
Symmetric polyarthritis: represents the most common presenting complaint clinically. Usully worse in the morning.
Areas of involvement most commonly are the small joints of hands, wrists (PIP, MCP), knees, and shoulders
Tenderness, edema, and effusions accompany a polyarthritis that is symmetric, nonerosive, and usually
nondeforming.
Characteristic hand deformities are swan neck deformities that result from recurrent synovitis and inflammation of
the joint capsule, tendons, and ligaments. These deformities are usually reducible and nonerosive.
Deforming non-erosive arthropathy: due to ligamentous laxity and muscle contracture, not articular destruction.
More common in long-standing disease. Non-erosive arthritis involving two or more joints can be diagnostic. The
presence of deformities without erosions differentiates it from rheumatoid arthritis. It develops approx. in 5-40% of
patients when articular abnormalities are present.
Myositis: clinically observed in 30-50% of patients.
Jaccoud arthropathy is the term used to describe the nonerosive hand deformities due to chronic arthritis and
tendonitis that develop in 10% of patients with SLE.
The most common radiographic anomalies in SLE are periarticular osteopenia and soft-tissue swelling without
erosions.
Radiographic features
Demonstrates soft tissue swelling of the involved joints(interphalangeal joints is most common), periarticular
osteoporosis, and normal joint spaces. Carpal instability may be seen in 15% of patients
Osteonecrosis – most common location is femoral head – manifests as focal pain
Calcifications linear or nodular calcification in the subcutaneous and deep soft tissues may be seen, specially around
small joints of extremities.
Stress fractures
Osteomyelitis and septic arthritis
20. Tendinopathies: include tenosynovitis, bursitis, spontaneous tendon weakening and eventually
rupture, more affecting weight-bearing joints as a complication of steroid therapy. Imaging
features also include capsular swelling, edematous and proliferative tenosynovitis and synovial
hypertrophy
Subcutaneous nodules: particularly over flexor tendons of the hands
Diagnosis is based on clinical presentation, ANA screening, imaging findings, ACR diagnostic
criteria, and lab tests including: CBC, antiphospholipid antibodies, anti-dsDNA, and anti-Sm
antibodies, ESR(elevated), CPR (normal in flare ups).
Treatment
Hydroxychloroquine is recommended in all patients
NSAIDS to manage arthralgia
Corticosteroids, dose depends on severity, but they are given for short time to minimize side
effects
Methotrexate and azathioprine should be considered in case of poor symptom control after a trial
of corticosteroids and hydroxychloroquine.

23. Scleroderma systemic
Scleroderma is an autoimmune connective tissue disorder characterized by multisystem fibrosis and
soft tissue calcification.
There are two primary types of scleroderma: localized and systemic (also called systemic sclerosis).
The disease is characterized by widespread deposition of collagen and other extracellular matrix
proteins. Occurs as a result of an abnormal immune response. Small vessels are involved early in the
disease, accounting for the involvement of organs with a dense capillary network. This results in
perivascular fibrosis and gradual luminal stenosis.
Raynaud phenomenon occurs in almost all patients with systemic sclerosis
Musculoskeletal Manifestations
Scleroderma may affect joints (arthritis, arthralgia), tendons (rubs, tenosynovitis) and muscles
(myalgia, weakness, more rarely myositis). Friction tendon rubs, seen on the hands, knees, and
ankles, indicate a poor prognosis. Digital retractions in flexion due to skin sclerosis and calcinosis,
lead to major functional disorders.
Limitation of movement, and joint swelling may be present. Systemic sclerosis begins as joint pain in
15% of patients. It begins as inflammatory myopathy in 10% of patients. Weakness is present in 80%
of patients
25. Musculoskeletal features
Phalangeal changes consisting of bone absorption, skin atrophy, and soft tissue
calcification. These features are classic, and their presence alone should suggest the
correct diagnosis. In some cases however the joint changes predominate. The wrist is
frequently involved. The interphalangeal joints are also affected but to a lesser degree
and in an asymmetric manner.
The presence of soft tissue calcification is extremely important. It’s rarely seen in
rheumatoid arthritis or SLE. When identified, soft tissue calcification is therefore
considered diagnostic for scleroderma and in some patients is the only differential
feature.
26. Musculoskeletal manifestations
Radiographic features
Bone changes
Acro-osteolysis (resorption of the distal phalanges)
Periarticular osteopenia
Joint space narrowing
Erosions
Severe resorption of the first CMC joint with radial subluxation is a characteristic
feature on hands radiographs
Soft tissue changes
Subcutaneous and periarticular calcification
Atrophy, specially at tips of fingers
Flexion contractures
27. Other less common documented musculoskeletal findings:
rib resorption (bilateral superior rib notching, predominantly along posterior surface),
mandibular angle resorption (+/- loss of lamina dura), radius and ulnar resorption
Terminal phalangeal sclerosis
Serological markers
Elevated ESR
RF – positive in 30-40% of patients
Antinuclear antibodies – 35-95% of patients
Anti SCL-70: positive in 30-70% of patients, particularly in limited disease
Anti-centromere antibodies (20-40% of patients, in limited disease particularly)
28. Musculoskeletal symptoms treatment
Carpal tunnel syndrome symptoms may require local corticosteroid injections although
frequently these symptoms resolve spontaneously.
Myositis may be treated cautiously with steroids (first choice), or with methotrexate or
azathioprine in corticosteroid-resistant cases or when there are contraindications to
corticosteroid use. Doses of prednisone greater than 40 mg/d are associated with a higher
incidence of scleroderma-associated renal crisis.
Arthralgia’s can be treated with acetaminophen and nonsteroidal anti-inflammatory drugs
(NSAIDs).
