– UC is not one disease
– CD is not one disease
– Each patient is unique
• Chronic disease management
– Educate and empower patients
– Collaboration between primary provider, gastroenterologist and other providers
Types of IBD
• Ulcerative Colitis
• Crohn’s disease
• Indeterminate colitis
• Microscopic colitis
• Pouchitis

NOD2/CARD15
• 25–35% of Caucasians with CD have 1‐2 NOD2 mutations
• Two mutations
• One mutation → x 20‐40 risk
→ x 2‐4 risk
• Youthful onset
• Ileal disease (rather than colon‐only)
• Fibrostenotic behavior
NOD2/CARD15
• Expressed in macrophages, dendritic and ileal Paneth cells
• Cytosolic receptor for bacterial cell wall peptidoglycan • Activates NF‐κB
• CD: Loss of function mutation
• Decreased defense to gut bacteria

Defective Handling
Of Bacteria
NOD2

IRGM
Th17 Pathway/ IL23
IL23R
IL12B
TYK2
JAK2
STAT3
Unifying hypothesis
• Primary dysregulation of the mucosal immune system, leading to excessive immunologic responses to normal microflora
• Changes in the composition of gut microflora and/or deranged epithelial barrier function may facilitate the abnormal immune response

Classic Extra‐intestinal Manifestations (EIMs)
Joint
• Peripheral arthritis
• Sacroiliitis
• Ankylosing spondylitis (SpA)
Skin
• Erythema Nodosum (EN)
• Pyoderma Gangrenosum (PG)
Liver
• Primary Sclerosing Cholangitis (PSC)

11
11/7/2014
Relation of EIMs to colitis
• Usually in patients with UC or Crohn's colitis
• Peripheral arthritis, EN, and episcleritis are related to the activity of the colitis –More common in extensive colitis and pancolitis • Ankylosing spondylitis, sacroiliitis, and PSC are independent of disease activity
• PG and iritis may or may not be related to disease activity Orchard, Gut 1998

Managing the risk of infection
•
•
•
•
•
Vaccinations (Flu, pneumovax, HPV, HAV, HBV)
Screen for TB and HBV
Warn patient about risk, avoidance to exposure
Vigilance
Fever? Rigors? Night sweats? Malaise?
– Patients should carry a thermometer – call if T>100.5‐101
• Think about unusual infections
• Always err on the side of caution
21
11/7/2014
Causes of Intestinal Obstruction in CD
• Stricture plus dietary indiscretion
• Acute active inflammation superimposed on a stenotic bowel segment
• Adjacent phlegmon or abscess with mass effect
• Intra‐abdominal adhesions Management of Obstruction
• NPO, nasogastric aspiration, correct fluid and electrolyte disturbances, and avoid narcotics
• Consult an experienced surgeon
• Steroids or infliximab if symptoms and signs of systemic inflammation (fever, night sweats, arthralgias, elevated ESR and CRP) 22
11/7/2014
Management of Obstruction
• Repeated episodes of SBO due to fibrostenotic CD are treated with surgery
• Strictured ileocolic anastomoses can be dilated endoscopically
Abscesses in CD
• Drainage (percutaneous)
• Treatment with antibiotics
• Supportive therapies: NPO, TPN, IVF and electrolytes
• No corticosteroids
• Infliximab vs. surgery
23
11/7/2014
Perianal CD
•
•
•
•
•
Tags, fissures, abscesses, fistulae, strcitures
20‐40% incidence Association with rectal and colonic disease
Drainage, fluctuance, tenderness, induration, DDx: Ca (squamous, adeno, lymphoma), hidradenitis suppurativa, infxn (TB, HIV, HSV), Seton
• Continually drains fistula
• Prevents abscess formation
• Reduces peri‐fistula inflammation
• Can be left in place indefinitely

Common mistakes in UC
•
•
•
•
•
•
•
Not using topical therapies
Routinely prescribing antibiotics
Routinely obtaining a CT scan
Not feeding the patient
Not consulting surgery
Not knowing when to call it quits
Prematurely converting IV to oral steroids
25
11/7/2014
Common mistakes in CD
• Missing stricturing or penetrating CD • Rx stricturing or penetrating CD with steroids
• Perianal disease: – Treating with steroids
– Delaying drainage of abscess
• Delaying surgery for stricturing disease
• No plan to prevent post‐op recurrence
• Excessive use of CT
Surgery for UC
• Curative
• Proctocolectomy with – end ileostomy
– ileal pouch anal anastomosis (IPAA)
26
11/7/2014
Surgery for CD
• Not curative
• High risk of recurrence
• Intestinal obstruction
– Resection
– Stricturoplasty
• Fistulae and abscesses
– Resection
Role of primary care physician
27
11/7/2014
Role of primary care physician
• Care coordination
• Reinforcing the message
–Balancing benefits and risks
–Encouraging compliance
–Infection risk
Communicating benefits and risks
•
•
•
•
•
IMM and biologics dramatically improve QOL
There are serious, but very rare side effects
Benefits generally outweigh the risks
Understand the trade‐offs
Individualize decision
28

1
• Goals of the talk
• Discuss few key points to remember when working up common hematological malignancies.
• Lymphoma/ lymphadenopathy
• Multiple myeloma.
• Leukemia/MDS/MPN‐ not included
2
• There are no standard screening guidelines for hematological malignancies.
• Usually patient presents to ER or PCP’s office
3
• 20 year old women with no past medical history presents with neck lymphadenopathy palpable 2x2 cm, cough for 6 months ,basic evaluation included CT of chest shows large right mediastinal mass
about 10 cm. • Excisional bx if palpable and accessible, because high likely Lymphoma based on the imaging and age. 4
• 66 year old obese women with left axilla Lymphadenopathy, • CBC normal and rest exam normal, ROS normal.
• Work up for breast cancer.
5
• 67 year old man who is a heavy smoker, now with mediastinal, neck and axilla Lymphadenopathy, and peripheral blood shows total WBC of 15,000. differential include 90% lymphocytes.
• Peripheral blood for flow cytometry, likely CLL, no biopsy indicated usually (there are exceptions)
6
• Lymphadenopathy, an abnormality in the size or character of lymph nodes, is caused by the invasion or propagation of either inflammatory cells or neoplastic cells *
• It results from a vast array of disease processes, can be very non specific.
• Work up always individualized.
• Malignancy is rare.
*Am Fam Physician. 2002 Dec
7
• Localized lymphadenopathy can be observed for 2‐4 weeks
• provided history and physical examination suggest no malignancy
• Tx if infections, if indicated. • Biopsy if not resolved in 2‐3 weeks • immediately if suggesting malignancy.
• Multidisciplinary approach

12
• But some are aggressive or very aggressive…
• grows quickly and causes serious symptoms
• Diffuse large B‐cell lymphoma • Burkitt's lymphoma • Always need treatment
• Urgent work up, urgent treatment. • Time is very important !

14
Low grade vs high grade on PET.CT 15
• General manifestations.
• Depending on the affected area, nodes, organs‐ mass effect
• Lymphocytosis‐ Leukemic phase
• B symptoms‐ wt loss, fever, night sweats, fatigue • Skin rash ‐many types. • Paraneoplastic
• Leukocytosis, thrombocytosis, anemia, eosinophilia, high total protein
• Indolent lymphomas can be asymptomatic for months to years
16
Mediastinal mass, young patients.
• 4 T.
‐Thymomas
‐Thyroid
‐Teratoma
‐"Terrible" lymphoma • Hodgkin's lymphoma
• More common
• Non Hodgkin's • Less common
• Acute lymphoblast Lymphoma/Leukemia.
• Primary mediastinal
Lymphoma.
• Sarcoidosis.
17
Lymphoma on the skin
Present as simple to severe rash, itching,
might need repeat biopsy , review by dermato pathology-experts
18
• Initial evaluation
• Clinical exam, History
• Localized, Generalized, associated symptoms.
• Review medications‐
• Phenytoin, allopurinol, hydralazine, etc. • Infections‐ acute chronic?
• HIV, TB, Syphilis, EBV etc, • Inflammations acute = chronic
• Sarcoidosis, lupus, other autoimmune disease
• CBC, CMP, HIV.
• Imaging CT‐PET/CT.
19
• Large tissue sample.
• avoid Fine Needle Aspiration when ever possible
•
•
•
•
acurate Dx, subtypes, molecular evaluations.
Some represent lower ‐higher grade within a single node
1‐10% of node is malignant ! In Hodgkin's lymphoma.
Can have granuloma, atypical, reactive finding as a part of malignancy and infections and inflammations.

• Excisional biopsy‐ depending on the location
• general surgeons/surgical oncologist/ENT/Urologist/ etc
• Core Bx
• FNA • Mediastinoscopy
• Bone marrow bx ‐usually use for staging. • Colonoscopy/EGD
• Bronchoscopy‐usually small samples not preferred if suspect lymphoma, unless no other easy choice.
21
• Which node to biopsy ?
• Depends on the clinical situation.
• Some times most palpable and easily accessible.
• But some times most avid of the PET/CT • Areas less preferred to biopsy
•
•
•
•
if radiology thinks reactive
Inguinal.
areas near inflammations. less intense on the PET/CT
22
• 69 year old man ,chronic smoker , with left side upper neck node palpable, hard, non tender 2x2 cm, for 1 month, growing slowly, voice has been different and loosing weight. • What type of biopsy first
• FNA ?
• Excisional ? • Core ?
23
• Head neck region.
• In general avoid open biopsies, unless neck dissection as primary treatment is planned by experienced surgeons
• It adversely affect the success of subsequent surgical resection
• Prefer ENT to biopsy this if suspect head and neck or cancer of unknown primary and only on the neck • Unless lymphoma was very likely
24
• How we made diagnose.
• Histology.
• Immunohistochemistry. • Flowcytometry.
• can be peripheral blood if suspicious cells.

• Approximately one‐quarter of patients 18 to 50 years of age with acute low back pain who received imaging tests had no identifiable indication for imaging Facts on Normal Patients
●In one study, 23 percent of asymptomatic adults had degenerative changes on plain x‐rays of the lumbar spine
●In a community‐based study of 188 individuals 40 to 80 years old, 60 percent of males and 67 percent of females had facet joint osteoarthritic changes on lumbar CT scans
●Disc herniations on MRI are seen in 22 to 36 percent of asymptomatic adults, and spinal stenosis is present in up to 21 percent of studies in patients over age 60 16
11/7/2014
MRI‐ Relevant vs Common Finding • One study reported that moderate or severe central stenosis, root compression, and disc extrusions were likely to be diagnostically relevant .
• Other MRI findings, however, were common in people without back pain (desiccation of discs, bulging discs, disc protrusion, loss of disc height).
Spondylolysis
• Spondylolysis (a defect in the pars interarticularis of the neural arch, usually due to a stress fracture) seen on radiograph is equally common in patients with and without low back pain symptoms

• Repeated imaging only recommended with new or different low back pain • MRI without contrast is generally considered the best initial test for most patients with low back pain who require advanced imaging • MRI enhancement with IV gadolinium allows the distinction of scar from disc in patients with prior back surgery
Harms of unnecessary imaging  Radiation exposure (for lumbar radiography and CT)
 Labeling Hypersensitivity reactions and contrast nephropathy (for iodinated contrast with CT)
 Potential association with subsequent unnecessary, invasive, and expensive procedures

Harms of unnecessary imaging  Radiation exposure (for lumbar radiography and CT)
 Labeling Hypersensitivity reactions and contrast nephropathy (for iodinated contrast with CT)
 Potential association with subsequent unnecessary, invasive, and expensive procedures
Talking to patients regarding Imaging • Risk factor assessment can almost always identify patients who require imaging • The prevalence of serious underlying conditions is low in patients without risk factors • The natural history of acute low back pain is quite favorable, but patients require reevaluation if they are not better after about 1 month 20
11/7/2014
• Routine imaging does not improve clinical outcomes but increases costs and may lead to potentially unnecessary invasive treatments, such as surgery • Imaging abnormalities are extremely common, especially in older adults, but most are poorly correlated with symptoms In most cases, treatment plans do not change after imaging studies • Back imaging is associated with radiation exposure, which can increase the risk for cancer in the case of lumbar radiography and computed tomography
Interventional Procedures • Epidural Injection Lumbar/ Cervical • Facet Injections • SI Joint injections
• Medial Branch Blocks/ Ablations
• Sympathetic Blocks

Epidural Steroid Injections
• “Epidural” describes an anatomic space
• Can be accessed via injection from different routs
– Interlaminar
– Transforaminal
– Caudal
22
11/7/2014
Summary of the Evidence
• Supports the use of both interlaminar and transforaminal corticosteroid injections for radicular pain as a result of spinal stenosis or disk pathology for short‐term analgesia
• Modest benefits for variable periods of 2 weeks to perhaps 3 months
Cervical Interlaminar ESI
• Most safely performed at the C7‐T1 level
• Epidural space is widest here
• Interlaminar openings is viewed in maximum diameter, usually with a caudocephalad angulation of the intensifier
23

• Cancer rehabilitation is a specialty of physical medicine and rehabilitation that aims to meet these needs for cancer survivors.
• Cancer rehabilitation plays a role throughout the continuum of cancer survivorship. 35
11/7/2014
●Preventative rehabilitation –use of early intervention and exercise to prevent or delay complications related to cancer or its therapies. ●Restorative rehabilitation –full reintegration of the patient back into society, community, school, or work.
●Supportive rehabilitation –re‐establish functional independence as much as possible. ●Palliative rehabilitation –The goals are to maximize patient comfort and caregiver support.
Role of the physiatrist ●A comprehensive functional assessment –
●Medication review –
• thorough review of the patient’s medications is necessary to evaluate for drug‐related side effects that could be contributing to any presenting impairment
• it is important to identify any potential drug interactions. ●Specific testing as indicated, including imaging, nerve conduction studies (NCS), electromyogram (EMG), or lab work. 36

NON INVASIVE CARDIAC TESTS - STANDARD
Standard tests:
 Exercise Tolerance Test (ETT)
 Imaging stress tests:
 Thallium/SestaMIBI
 Stress ECHO
 Pharmacologic stress tests
New tests:
 Coronary calcium scoring
 CT coronary angiography
 Cardiac MRI and MRA
CT CORONARY CALCIUM SCORES
CT of the chest without contrast
Evaluates density of calcium deposits in the coronary
arteries
Calcium deposition roughly correlates to the severity
and age of the atherosclerotic plaque formation
Predictive of future cardiac events
Does NOT correlate to severity of stenosis
Cannot assess for the presence of ischemia
CT CORONARY CALCIUM SCORES
If you have high calcium
scores, you have CAD.
However, you do not know
the severity.
Early, soft plaque typically
does not have significant
calcium and will therefore
not have high scores.
Useful screening tool?

RISK ASSESSMENT
CHD Risk—Low Defined by the age-specific risk level that is below
average. In general, low risk will correlate with a 10-year absolute
CHD risk less than 10%.
• CHD Risk—Moderate Defined by the age-specific risk level that is
average or above average. In general, moderate risk will correlate
with a 10-year absolute CHD risk between 10% and 20%.
• CHD Risk—High Defined as the presence of diabetes mellitus in a
patient 40 years of age or older, peripheral arterial disease or other
coronary risk equivalents, or a 10-year absolute CHD risk of greater
than 20%.

relevant but cost effective
WHAT IS AN APPROPRIATE STUDY?
• An appropriate imaging study is one on which the
expected incremental information, combined with
clinical judgment exceeds the expected negative
consequences by a sufficiently wide margin for a
specific indication that the procedure is generally
considered acceptable care and a reasonable
approach for the indication
