Lagusta: o boy see questions!!!! i don diieeeee!!!!!

*goes to the bush to read*

fedico21: Answer With clinical reason;
1.Following hemisection of the spinal cord at the level of approximately
T3, a patient experiences loss of pain and temperature on the left
side of the leg. Which of the following tracts was affected by the hemisection
of the cord that could account for this deficit?
a. Right fasciculus cuneatus
b. Right fasciculus gracilis
c. Right spinothalamic tract
d. Left spinothalamic tract
e. Left corticospinal tract

2. A 35-year-old man injured his thoracic spine in a motor vehicle accident
2 years ago. Initially he had a bilateral spastic paraparesis and urinary
urgency, but this has improved. He still has pain and thermal sensation loss
on part of his left body and proprioception loss in his right foot. There is
still a paralysis of the right lower extremity as well.

This patient has which spinal cord condition
a. Brown-Séquard (hemisection) syndrome
b. Complete transection
c. Posterior column syndrome
d. Syringomyelic syndrome
e. Tabetic syndrome

Androstyn: the answer to one is left corticospinal tract the corticospinal tract decussates at the cerebellomedullary junction c one atfter c one injury causes ipsilateral damage because the tract no longer decussates

Androstyn: its right spinothalamic tract

lomaxx:

Androstyn: pls how do i get dr najeebs lectures

Amb Fitsaint: Thanks for dat Dr Tolu.. I am grateful for dis

Afeisume: dr. Tolu aw cn i contact u 4 info on u.i

joeydozzy: @[b]fedico 21
I think the answer is the right spinothalamic tract cos it carries pain and thermal sensation of the opposite side of the body after it crosses over at the posterior horn as the second order neurone

the second should be Brown Sequard syndrome since its an industrial
ipsilateral loss in the dorsal column lemniscus and contralateral loss in the spinothalamic pathway

joeydozzy: lol I've forgotten most parts in that. Still surprised I remembered a little.
Thanks for reviving my memory

fedico21:
You didn't do bad at all. Are you in practice already?

labodinho: Helo,plz any Dr shuld help me out here.Frm ma findings i got this when studying.Is there any biochemistry test that can be carried out to detect METHEMOGLOBINEAMIA(Blue Baby Syndrome) in baby's?? If Yes,discuss dat.What's the effect and duration of living(If i'm right bout dah) of baby with HYPOXIA....I'm noh ah Dr yet sir's n ma's.

Emzybrown: For lab dudes which parasitic infection is associated with stearrhoea?

2. At what time do you obtain blood sample for this microfilaria worms a. Wuchereria Bancroft, brugia melayiii, loaloa, mansonella ozzardi, onchoncerca volvulus?

3.explain the principle of oral glucose tolerance test and what is renal threshold of glucose.

4. Outline stages of tissue processing in a histopathology laboratory??

5.parasitological techniques for detection of trypanosomiasis
Well this are cheap questions though?

lomaxx: I think Lab Medicine is cool

Giardiasis. Caused by Giardia lamblia. Causes steatorrhea by blocking the absorption of fat.




Microfilaria appear intermittently in the peripheral circulation. The blood should be examined at different intervals over a 24-hour period to achieve the best chances of detection. Bancroftian and brugian filariasis tend to show nocturnal periodicity, so it is recommended that samples be collected between 10:00 pm and 2:00 am.



Normally, insulin maintains blood glucose within a normal range following an oral glucose load. Failure of insulin secretion, or resistance to insulin action, will result in an elevation in blood glucose.

Renal threshold of glucose = 160 - 180mg/dl


They include:
*Fixation - to fix cellular constituents in a physical and chemical state so they would withstand subsequent stages with minimal loss of tissue architecture. Formalin , evthyl alcohol is used.
*Dehydration using alcohol of increasing strength
*Clearing
*Embedding
*Cutting
*Staining



*Blood smear
*Haematocrit centrifugation technique for buffy coat examination
*Chancre aspirate
*Lumbar puncture for CSF Assay
*Bone marrow aspirate

Have you seen the results of people writing the CBT exams? We're talking OAU here, not some other school. 245 is low, trust me...unless he has an oga @ the top.
