0 Chilaiditi syndrome

Chilaiditi syndrome is a rare condition when pain occurs due to transposition of a loop of large intestine (usually transverse colon) in between the diaphragm and the liver, visible on plain abdominal X-ray or chest X-ray
Normally this causes no symptoms, and this is called Chilaiditi's sign. The sign can be permanently present, or sporadically. This anatomical variant is sometimes mistaken for the more serious condition of having air under the diaphragm (pneumoperitoneum) which is usually an indication of bowel perforation. This may lead to unnecessary surgical interventions.
Chilaiditi syndrome refers only to complications in the presence of Chilaiditi's sign. These include abdominal pain, torsion of the bowel (volvulus) or shortness of breath.

0 Hamman's syndrome and sign

Hamman's syndrome is a syndrome of spontaneous subcutaneous emphysema (air in the subcutaneous tissues of the skin) and pneumomediastinum (air in the mediastinum, the center of the chest cavity), sometimes associated with pain.
Hamman's syndrome can cause Hamman's sign.
The syndrome is caused by alveolar rupture and can be seen post partum.
It most commonly occurs in young women.

Hamman's sign (rarely, Hammond's sign or Hammond's crunch) is a crunching, rasping sound, synchronous with the heartbeat, heard over the precordium in spontaneous mediastinal emphysema produced by the heart beating against air-filled tissues.
 It has been described as a series of precordial crackles that correlate with the heart beat and not the respirations.

Hamman's crunch is caused by pneumomediastinum or pneumopericardium, and is associated with tracheobronchial injury due to trauma, medical procedures (e.g., bronchoscopy) or proximal pulmonary bleb rupture. It is commonly seen in Boerhaave syndrome.(also here there is Mackler triad)

1 Tree in bud



Q. Most common cause of tree in bud appearance on HRCT chest is?
a. Endobronchial spread TB
b. Haematogenously spread TB
c. Pneumocystis Carnii
d. RSV

ANSWER:
Ans : A.. endobronchial spread TB

NOTE: similar ques was asked in aiims nov. 2010 where the difference was that the patient had undergone bone marrow transplant and then showed this Tree In Bud appearance, so then the answer will be Pneumocystis carnii.

0 Wilson's Disease

Q.True in Wilson's disease?
a.high plasma copper
b.low urinary copper
c.high copper levels in liver
d.high ceruloplasmin

ANSWER:
Ans : C
Laboratory tests measure the amount of copper in the blood, urine, and liver tissue. Most people with Wilson disease will have a lower than normal level of copper in the blood and a lower level of corresponding ceruloplasmin, a protein that carries copper in the bloodstream. In cases of acute liver failure caused by Wilson disease, the level of blood copper is often higher than normal. A 24-hour urine collection will show increased copper in the urine in most patients who display symptoms. A liver biopsy—a procedure that removes a small piece of liver tissue—can show if the liver is retaining too much copper. The analysis of biopsied liver tissue with a microscope detects liver damage, which often shows a pattern unique to Wilson disease.

0 Facts about 4th nerve

Q. which of the following is not true about trochlear nerve
a. has longest intracranial course
b. supplies ipsilateral sup. oblique
c. arise from dorsal aspect
d. enters orbit through sup. orbital fissure outside annulus of zinn

ANSWER:
here answer clearly is option B because 4th nerve supplies contralateral sup. oblique..

Thus in AIIMS and ALL INDIA ans. for the longest inracranial course is 4th nerve only
