Question
While walking in the snow, Jim falls and lands awkwardly on his head. Jim goes to hospital, but Jim’s doctor cannot explain why Jim fell. You are asked to investigate everything that Jim was doing before the accident, to try to find a cause for the fall.
Question 5: Endocrinology
Jim wakes up and tells his doctor that while he was walking in the snow, despite wearing a super-thick snowsuit, he was feeling really cold, much colder than normal. Jim says he doesn’t recall feeling so cold at any other time. Jim wonders whether this is related to the curious lump that seems to have developed around his neck.
a) Without any further evidence, what do you think is an appropriate diagnosis for Jim?
b) What is your evidence for the diagnosis you made in a)?
c) What other symptoms would you expect Jim to have?
d) Describe the dysregulation of the endocrine gland leading the clinical features described in a) to c). In your answer describe the normal regulation of the endocrine gland.
e) Speculate as to whether this final diagnosis might explain Jim’s fall, and briefly explain why or why not. Why do you think Jim fell? (Note: there is no right answer – go wild!)
Explanation / Answer
?#Answer-(a) without any further evidence ithink this problem a result of hypothyroidism.thyroid control heat tolrance by metabolism.regulate the body temp.by hypothalamus.hypothalamus regulate thermostate of body .
(b)most evidence for it cold in tolrance.cold intolrance extremely sensetive to cold than normal person.more severe feeling of chillness when in outdoor.cold not resolve despite adding extra layers of clothing.
(C) cold intolrance is unusual sensitive to cold temperatures.
-difficult to achieve a comfortable body temperature regardless of the situation.
-cold only in specific parts of body such as hand or feet.
-weight gain,fatigue, depression,dry skin,
-difficult concentration,muscle weakness,high cholesterol levels
(d)thyroid hormone is responsible for stimulating metabolism,lower throid hormone leads to lower metabolism,which leads to less heat production and poor to heat tolranceof the cold.normal functions of thyroid gland normal metabolism produce enough heat by metabolism but in hypothroidisn doesn't it.
(e)-exposre to extreme cold is a stress on the body, especially thyroid function impaired.low level of thyroid hormone doesn't normal thermorgulation.hypothalamus have thermoregulatry .this condition doesn't have thermostate.and in extremely cold condition fail thermirgulatry e doesn't produce enough heat .in very cold intolrance body not tolerate the chills and extremely condition fell down.
