Important additions 

Spesolimab , sold under the brand name Spevigo, is a monoclonal antibody used for the treatment of generalized pustular psoriasis. It is an interleukin-36 receptor (IL-36R) antagonist.

Certolizumab and golimumab are licensed for psoriatic arthritis, not for cutaneous psoriasis

Phototherapy

 Important note

Phototherapy is an important modality of treatment and hence very important for theory as well as clinical exam.

U must have a clear concept of every single step regarding phototherapy, how to begin, indications, MED calculation, adverse effects and contraindications.

 

Above shared voice note gives a concise yet easy understanding of how PUVA is used.

In long case of Immunobullous which is a must to come always to most of the candidates, ua viva usually begins with present ua case and then how will u manage this case. In long case no 1 asks u about the types or classifiaction so dun waste ua time preparing tht.

U must know the S2 guidelines, rituximab protocol and dose, tapering of steroids, preferred choice of immunosuppressive therapy to be used.

Refractory disease

Bad prognostic factors

Monitoring of disease

What are the eye changes in systemic sclerosis??*

 

– start from outside… eyelid stiffness, eyelid telengiectasis

– cataracts

– glaucoma

– keratoconjuctivitis sicca

– optic neuropathy

– orbital fat atrophy

 

What are the git findings ??

 

Remember  findings from top to bottom, you will never forget

 

  1. Start from mouth i.e microstomia & icrocheilia ( this is dec in mouth width)
  2. Xerostomia
  3. Then comes teeth, enamel is damaged
  4. Dysphagia/ regurg
  5. Gastroparesis
  6. Small bowel dysmotility
  7. Large bowel diverticulosis
  8. Ano rectum… this is 2nd most common site affected after oesophagus, internal anal sphincter is involved

 

What are the bone changes in systemic sclerosis ?*

 

– phalangeal resorption

– erosive arthropathy ( pestle and mortar deformity)

– flexion deformities

– acro osteolysis

– joint space narrowing

-severe resorption of 1st carpometacarpal joint with radial subluxation and this is characteristic finding…

– calcinosis

 

 

 What are soft tissue changes ?*

 

 

– subcutaneous and periarticular calcification

– atrophy of finger tips

 

What are the ecg findings in systemic sclerosis ?*

 

 ST-T changes

 

– conduction abnormalities like LBBB, first degree AV block, prolonged QT, SVT, VT

 

 

 What are the echo findings in systemic sclerosis?

*

diastolic dysfunction

valvular regurgitation

Right ventricular pathology

 

DETECT study

 

A non invasive method to tell us when to go for invasive right heart catheterization.

 

🔅Step 1

Calculate a score by measuring 6 parameters

 

-fvc predicted /dlco predicted

-telengiectasia yes or no

– anti centromere antibody yes or no

– right axis deviation on ecg yes or no

– serum urate level

– pro bnp level

 

( easy to remember 3 have yes or no, and 3 are values)

 

If the score is more than 300 then go for echo

 

🔅Step 2

You see right atrium area in cm2, 

TRJ (tricuspid regurgitant jet) velocity in m/s and step 1 total risk score

 

If its more than 35, then right heart catheterization is recommended..

 

HSCT considered in SSc when 👇🏻

 

Disease is rapidly progressive

Severe visceral involvement esp pulmonary involvement

Unresponsive to treatment

 

🔰 IMPORTANT 🔰

 

Systemic sclerosis is a very imp long case which always comes in exam, isolated or as a part of MCTD.

So its imp to know every aspect of it.

Like other long n short cases, examiner already makes his mind in the first 10mins after listening to ua history so its critically imp to have a firm grip over history taking and then on the examination.

Ua body language says it all about how many patients u have examined.

So practice as much as u can, ofcourse with a timer on ua bedside coz without time management even the best candidates face the bitterness if failure.

Happy learning😊

Important note

Mycosis fungoides is a very important long case

It must be kept in the dds of CAD,ABCD, psoriasis and leprosy, otherwise the examiner will already make his mind to fail the candidate.

Always ask questions specific for MF in above mentioned cases in history taking and palpate all the lymph nodes and liver spleen during examination, be it a long case or a short case to make sure it isnt MF.

Examiner will never spare u if u missed them.

If u did all these well then consider uaself in the safe zone after which ua viva will be easy in sha Allah.

Viva questions will be from the above voice notes and important tables which i have already shared.

Do not forget to mention the stage of the pt bcoz after mentioning MF in ua  dds, nxt question will be why MF and what is the stage of MF in tht particular patient.

Rest of ua viva will be based on how will u manage this patient, investigations, IHC markers and treatment ladder.
