Reno vascular hypertension

Q) Which of the following is true about reno vascular hypertension

a) Seen in young age group

b) Both kidneys are of same size

c) It is familial

d) Diuretics will control the hypertension

Answer for free

a

Renal artery occlusion creates ischemia of the kidney which releases renin. Hypereninemia leads to secondary hypertension. This further leads to conversion of angiotensin I to angiotensin II and vasocontriction and eventually release of aldosterone.

It is a disease of young adults and children

Size of the kidneys vary and diuretics do not control hypertension because the mechanism is high renin secretion which is unresponsive to diuretics.

a) N1 ipsilateral more than 6 cm

b) N2a ipsilateral single node between 3-6 cm

c) N2b is Multiple ipsilateral more than 6 cm

TNM Staging


NX Regional lymph nodes cannot be assessed
N0 No regional lymph node metastasis
N1 : Metastasis in a single ipsilateral lymph node <3 cm in greatest dimension
N2a:  Metastasis in a single ipsilateral lymph node >3 cm but not more than 6 cm
N2b:  Metastasis in multiple ipsilateral lymph nodes, none >6 cm in greatest dimension
N2c : Metastasis in bilateral or contralateral lymph nodes, none >6 cm in greatest dimension
N3 Metastasis in any lymph node >6 cm

Thyroid Questions

Q) Which of the following thyroid cancers do not take up radio active iodine

a) Medullary carcinoma thyroid

b) Papillary  carcinoma

c) Follicular carcinoma

d) Hurthle cell carcinoma

Free Answer

a - Medullary carcinoma

Medullary carcinoma of the thyroid is a tumor that arises from the C cells ie the parafollicular cells and not from cells of thyroid follicles.

These are not TSH dependent and hence do not take up radioactive iodine

Hurthle cell carcinoma is a variation of follicular carcinoma only.

In these tumors lymph node involvement is about 60%
