AIPGMEE 2016 Pathology MCQ

A 33-year-old man has experienced nausea and vomiting and has become mildly icteric over the past week. On physical examination, his temperature is 37.4° C. Laboratory studies show serum AST of 208 U/L and ALT of 274 U/L. Serologic findings for HBsAg and HBcAb are positive.
A liver biopsy specimen examined microscopically shows focal death of hepatocytes with a portal inflammatory cell infiltrate. Which of the following is the most likely mechanism by which his liver cell injury occurs under these conditions?
A Activated macrophage cytokine release
B Antibody-mediated destruction of HBsAg-expressing liver cells
C CD4+ lymphocyte recognition of circulating HBsAg
D CD8+ lymphocyte recognition of viral peptide presented by MHC class I molecules
E NK cell recognition of viral peptide presented by MHC class II molecules
Answer - D

Virus-infected cells are recognized and killed by
cytotoxic
CD8+ T cells. The T cell receptor on the CD8+ T cells
binds to the complex of viral peptide and MHC class I molecules
displayed on the surface of the infected cell. Natural
killer (NK) cells also recognize MHC class I molecules with
self-peptides, but this self-recognition inhibits NK cell killing.
Viruses that inhibit MHC I expression of peptides may
hide from cytotoxic cells, but not from NK cells. The other
listed options are not the major immune response to hepatitis
viral infection

B. Ebastine
C. Terfenadine
D. Astemizole
Mizolastine This nonsedating antihistaminic
is effective in allergic rhinitis and urticaria by
single daily dosing despite a t½ of 8–10 hr and no
active metabolite.

AIPGMEE 2016 SPM MCQ

A person has received complete immunization against tetanus 10 years ago, now he presents with a clean wound without any lacerations from an injury sustained 3 hours ago. He should now be given

(a) Full course of tetanus toxoid 

(b) Single dose of tetanus toxoid

(c) Human tetanus globulin

(d) Human tetanus globulin and single dose of toxoid

Ans. (b)

[Ref. Park 21/e p287, Park 22/c p286]

• In the given question, a person has received complete immunization against tetanus 10 years ago,

• Thus he is in immunity category B

• Now, he presents with a clean wound without any lacerations from an injury sustained 3 hours ago,

• Thus he should now be given single dose of tetanus toxoid

AIPGMEE 2016 Pediatrics MCQs

1. The best description of the Apgar score is that it:

A.Accurately predicts who will develop cerebral palsy

B.Assesses newborn infants in need of resuscitation

C.Accurately predicts a low umbilical cord pH

D.Is unaffected by maternal opiate pain relief

E.Accurately predicts newborn infants who will die in the neonatal period

ANS.B

EXPLANTION:-

The Apgar score is a practical method of systematically assessing newborn infants immediately after birth. A low score may be due to fetal distress but may also be due to a number of factors, including prematurity and drugs given to the mother during labor. The Apgar score was not designed to predict neurologic outcome. Indeed, the score is normal in most patients in whom cerebral palsy subsequently develops, and the incidence of cerebral palsy is low in infants with Apgar scores of 0-3 at 5 min (but higher than in infants with Apgar scores of 7-10). Low Apgar scores and umbilical artery blood pH predict neonatal death. An Apgar score of 0-3 at 5 min is uncommon but is a better predictor of neonatal death (in both term and preterm infants) than an umbilical artery pH ≤ 7.0; the presence of both variables increases the relative risk of neonatal mortality in term and preterm infants. Infants who fail to initiate respiration should receive prompt resuscitation and close observation. (See Chapter 88, page 536.)
