1) Hepatitis “D” Virus has HIGHEST mortality in ALL people EXCEPT‪#‎Pregnancy‬.
In Pregnant women: MOST LETHAL is Hepatitis E virus.

2) “While calculating Serum Osmolality the serum Na is multiplied by 2 to account for the accompanying ANIONS (mostly Cl- & HCO3-).”

3) Most Common cause of Metastasis to LIVER is primary cancers of Lung.

20) The MOST COMMON thyroid CA is Papillary (P-opular).
It also has P-sammoma bodies on histology.
It causes P-alpable lymph nodes (lymphatic spread)

21) ALL Quinolones lack anaerobic coverage EXCEPT Moxifloxacin.

22) COLD sensations are transmitted by myelinated “A-delta” fibers.
WARM sensations are transmitted by unmyelinated “C” fibers.

23) Sigmoid Colon:
I) MOST COMMON (MC) site of Colorectal Carcinoma.
II) MC site of Volvulus in Elderly adults (in young -> Cecum).
II) MC site of Diverticulosis.

24) Homocysteine level is ELEVATED in BOTH (Vit B 12 & Folate deficiencies) While Methylmalonic Acid level is NORMAL in Folate & ELEVATED in B12.

25) ALL ß-blockers are safe during gestation EXCEPT atenolol.
Once more:
ALL ß-blockers are safe during gestation EXCEPT atenolol.

26) Ectopic Pregnancy:
Most Common site: Ampulla.
Most common site for Rupture: Isthmus.

27) In SIADH = Serum Osmolarity DECreased

In Water Deprivation : Serum Osmolarity HIGH or Normal (#‎NEVERDecreased)

28) Oral Cavity:
Premalignant CONDITIONS = Submucous Fibrosis & Lichen planus.
Premalignant LESIONS = Erythroplakia & Leukoplakia.

29) All the EXTENSION movements (Elbow, Wrist, Fingers) of Upper Limb is innervated by Radial Nerve.

30) Treatment of Hyperthyroidism in Pregnancy:
Propylthiouracil in FIRST trimester.
Methimazole AFTER the first trimester.
[If they didn’t mention Trimester in question then SELECT PropylThioUracil (PTU)]

31) Urine extravasation in:
Rupture of
Penile urethra -> SCROTUM
Bulbar -> SUPERFICIAL perenial pouch
Prostatatic urethra -> DEEP perenial pouch

32) All RNA viruses replicate in the cytoplasm of the host cell EXCEPT Influenza & HIV.
All RNA viruses are single stranded EXCEPT Reovirus.

All DNA viruses replicate in the nucleus of the host cell EXCEPT Poxvirus.
All DNA viruses are double stranded EXCEPT Parvovirus.

33) ‪#‎Tamoxifen is an estrogen receptor ‪#‎AGONIST in the uterus.
#‎Raloxifene is an estrogen receptor #‎ANTAGONIST in the uterus.

Tamoxifen for ‪#‎PREmenopausal‬ women with high risk for breast cancer.
Raloxifene for #‎POSTmenopausal‬ women with high risk for breast cancer.

34) Isolated #‎6th cranial nerve palsy causes #‎HORIZONTAL‬ diplopia.
Isolated ‪#‎4th cranial nerve palsy causes #‎VERTICAL diplopia.

35) Diagnostic Test for Streptococcal #‎INFECTION: blood CULTURE.

Diagnostic Test for Strep infection #‎COMPLICATIONS‬ (Rh. Fever/PS-GN) : ASO titre.

36) E. Coli is the:
MOST COMMON cause of Pyogenic Peritonitis (visceral perforation).
&
MOST COMMON cause of Spontaneous Bacterial Peritonitis.

37) Most Common #‎aspiration‬ site is ‪#‎Right‬ ‪#‎LOWER lobe (doesn’t matter pt is standing, sitting, supine or dancing)

EXCEPTION: ONLY in ONE condition it can aspirate to Middle or even Upper lobe => in right sided position.

38) Pt CAN’T stand on his/her toes : Rupture of ‪#‎ACHILLES‬ tendon.

Pt can STAND on his/her toes but feel PAIN : Rupture of ‪#‎PLANTARIS‬tendon.

39) The main cause of Edema in Nephrotic Syndrome is Sodium Retention, ‪#‎NOT‬ Hypoalbuminemia.
(The Hypoalbuminemia is LESS important contributor)

40) Know the Difference:

Antibodies form ‪#‎IN‬: Spleen.
Antibodies form ‪#‎BY‬: Plasma Cells.

41) Q fever:
The ONLY rickettsial disease WITHOUT a ‪#‎rash‬.
The ONLY rickettsial disease NOT needing #vector for transmission.

42) Nasal deformity + granuloma + Acid Fast Bacilli = Leprosy.

Nasal deformity + granuloma + hematuria & positive c-ANCA = Wegner’s Disease.

43) Polycystic Kidney Disease:
The most common cause of Death is #ESRD – Renal failure.
[Ruptured Berry Aneurysm (SAH) is NOT correct]

44) Chronic hepatitis B is the most common cause of HCC worldwide with
chronic hepatitis C being the most common cause in Europe.

45) Location of Melanocytes in the skin: Stratum basalis (the deepest layer of the five EPIdermis layers.)

47) Down syndrome and Leukemia :
– Younger than 5 year old –> AML (M7 subtype)
– Older than 5 year old –> ALL

48) Respiratory Bronchioles:

49)
History of Asbestos exposure: Mesothelioma.
History of Smoking: Bronchogenic carcinoma.
History of BOTH (Smoking + Asbestos exposure) : Bronchogenic carcinoma.

50) The Key feature of SHOCK is TISSUE HYPOPERFUSION, not a specific level of systemic arterial Blood Pressure.

51) The most ACCURATE noninvasive index of core temperature is Esophageal temperature.
