Why do the students not recall some well-rehearsed answers during the examination time? How come those answers come back into their memory after the exam is over?

The answer lies in the property of synaptic fatigue. Repeated continuous learning by rote, before the exam, may result in the complete discharge of the transmitters stored at the specific synapses. During the course of the exam, there is no NT in those synapses; and hence, there is no transmission. Once the NT is repackaged, the transmission starts again, by which time the exam is over!

Shaving if done more than 20 minutes before surgery allows re-colonization. Two minutes with an appropriate agent is sufficient for scrubbing. Hypothermia is employed to protect brain and heart in neurosurgery and cardiac surgery respectively but has no significant impact on surgical site infection. Application of oxygen in perioperative period is known to reduce surgical site infections.

Clamshell thoracotomy (also known as bilateral anterolateral thoracotomy) is a technique used to provide complete exposure of the thoracic cavity (heart, mediastinum and lungs). #Surgery

Polycoria is a pathological condition of the eye characterized by more than one pupillary opening in the iris. It may be congenital or result from a disease affecting the iris. It results in decreased function of iris and pupil, affecting the physical eye and visualization.

#Surgery Mesenteric Ischemia
Acute mesenteric ischaemia is the sudden decrease in blood supply to the bowel, resulting in bowel ischaemia and, if not promptly treated, rapid gangrene and death.

Traditionally, mesenteric ischaemia presents with a generalised abdominal pain, out of proportion to the clinical findings, although it can often be more variable or subtle than this. The patient will typically complain of a diffuse and constant pain, with associated nausea and vomiting present in around 75% of cases.

On examination, the abdomen is often unremarkable* and the patient may find it difficult to localise the pain. However, remember late stage bowel ischaemia and necrosis can present as bowel perforation. Importantly, take note of any potential embolic sources, such as AF, heart murmurs, or signs of previous valvular replacement surgery.
