Hypoxic-anoxic injury.

 A 27 years old female patient with right hemiparesis. What is the diagnosis? 


Hypoxic – anoxic injury.

This can occur when someone is drowning, choking, suffocating, or in cardiac arrest. Brain injury and carbon monoxide poisoning are other possible causes of brain hypoxia. The condition can be serious because brain cells need an uninterrupted flow of oxygen to function properly. Severe global hypoxic-ischemic injury in this population primarily affects the gray matter structures. The predominance of grey matter injury is due to its high metabolic requirement for oxygen and glucose to supply a large number of synapses. This makes grey matter more susceptible to hypoxic-ischemic injury.

If IUI or OI/TI CYCLE  one or two dominant follicles are recruited  If IVF cycle multiple follicles are recruited  Mention number of follicle and sizes .. measure in two dimensions at least (each follicle) 2. Till the follicle size reaches 17-18 mm .. time to go for pick up in IVF cycles or for trigger in IUI or oi and ti cycles Usually follicles grow at speed of 1-2 mm per day  3. Regarding endometrium when u do day2/3  scan endometrium should be thin (<5mm) ... if it is thick than do see endometrium again once period is over (day 5-6) ... I’d still thick than gynaec usually do some scratching or they don’t proceed in same cycle 4. Endometri...
