Q

What occurs in primary hyperparathyroidism?

A

Cause –> solitary parathyroid adenoma –> increase release of PTH

Result:
–> high calcium and low phosphate
–> increase bone turnover by OC activation –> more ALP

Presentation: hypercalcaemia symptoms: constipation and mood changes

Q

Describe secondary hyperparathyroidism:

A

Chronically low serum [Ca2+] –> parathyroid hyperplasia

Increased PTH secretion will not be able to reverse chronically low calcium and high phosphate caused by condition.

PTH –> excessive bone turnover –> high ALP

Presentation: bone pain, tenderness, proximal myopathy and recurrent fractures

Subacute combined degeneration of the spinal cord is due
vitamin B12 deficiency resulting in impairment of the: **1.dorsal columns** --> impaired proprioception and vibration **2. lateral corticospinal tracts** --> muscle weakness, hyperreflexia and spasticity --> brisk knee reflexes --> absent ankle jerk **3. spinocerebellar tracts** --> sensory ataxia: gait abnormalities --> positive romberg's sign
