Q. 3

A 35 – year old male develops involvements of PIP, DIP and metacarpophalangeal joints with sparing of wrist and carpometacarpal joints. The probable diagnosis is:

 A

Psoriatic arthopathy

 B

Osteo arthritis

 C

Rheumatoid arthritis

 D

Pseudo gout

Ans. A

Explanation:

Answer is A (Psoriatic arthropathy):

Psoriatic arthritis involves PIP, DIP and metacarpophalangeal joints, and may or may not involve the wrist.

  • Involvement of DIP makes rheumatoid arthritis unlikely. DIP is spared in rheumatoid arthritis.
  • Involvement of metacarpophalangeal joints makes osteoarthritis unlikely. Metacarpophalangeal joints and carpometacarpal joint with the exception of base of thumb are spared in osteoarthritis.

Q. 4

Proximal interphalangeal, distal interphalangeal & 1st carpometacarpal joint involvement and sparing of wrist is a feature of:

 A

Rheumatoid arthritis

 B

Pseudogout

 C

Psoriatic arthropathy

 D

Osteoarthritis

Q. 4

Proximal interphalangeal, distal interphalangeal & 1st carpometacarpal joint involvement and sparing of wrist is a feature of:

 A

Rheumatoid arthritis

 B

Pseudogout

 C

Psoriatic arthropathy

 D

Osteoarthritis

Ans. D

Explanation:

Answer is D (Osteoarthritis) :

Sparing of wrist and metacarpophalangeal joint with involvement of base of thumb (i.e. carpometacarpal joint) is very characteristic of `osteoarthritis’.

Both DIP (Herbeden’s nodes) and PIP (Bouchard’s nodes) are involved in osteoarthritis.Q

DIP is the most common form of idiopathic O.A.

Q. 6

A patient has hyperphosphatemia with short metacarpals and associated cataract. The diagnosis is:

 A

Pseudohypoparathyroidism

 B

Hypophophatasia

 C

 D

Osteomalacia

Q. 6

A patient has hyperphosphatemia with short metacarpals and associated cataract. The diagnosis is:

 A

Pseudohypoparathyroidism

 B

Hypophophatasia

 C

Hyperparathyroidism

 D

Osteomalacia

Ans. A

Explanation:

Answer is A (Pseudohypoparathyroidism):

The presence of hyperphosphatemia (Serum phosphate) along with characteristic brachydactyly suggests the diagnosis of pseudohypoparathyroidism.

 

Pseudohypoparathyroidism

  • This is a hereditary disorder associated with symptoms and signs of hypoparathyroidism despite an elevated PTH level (pseudohypoparathyroidism)
  • This is produced as a result of deficient end organ response to PTH.

Q. 7

 A

Klinefelter syndrome

 B

Turner syndrome

 C

Q. 7

Webbing of neck, increased carrying angle, low posterior hair line and short fourth metacarpal are characteristics of:

 A

Klinefelter syndrome

 B

Turner syndrome

 C

Cri du chat syndrome

 D

Noonan syndrome

Ans. B

Explanation:

Answer is B (Turner’s Syndrome) :

Noonan syndrome presents with most features similar to Turner’s Syndrome. Webbing of neck, increased carrying angle, low hair line are present in both Noonan’s and Turner’s Syndrome but short fourth metacarpal is characteristic of Turner’s Syndrome only.

Term Noonan syndrome has been applied to males and females who present with phenotypic features of Turner’s Syndrome but have a normal Karyotype (46X, Y or 46 XX)

Turner’s Syndrome

Noonan’s Syndrome
