Classification
| Classification of hyperparathyridism | |||
|---|---|---|---|
| Features | Primary hyperparathyroidism | Secondary hyperparathyroidism | Tertiary hyperparathyroidism |
| Pathology | Hyperfunction of parathyroid cells due to hyperplasia, adenoma or carcinoma. | Physiological stimulation of parathyroid in response to hypocalcaemia. | Following long term physiological stimulation leading to hyperplasia. |
| Cause | |||
| Associations | May be associated with multiple endocrine neoplasia. | Usually due to chronic renal failure or other causes of Vitamin D deficiency. | Seen in chronic renal failure. |
| Serum calcium | High | Low/Normal | High |
| Serum phosphate | Low/Normal | High | High |
| Management | Usually surgery if symptomatic. Cincacalcet can be considered in those not fit for surgery. | Treatment of underlying cause. | Usually cinacalcet or surgery in those that don't respond. |
Epidemiology PE & DVT
Incidence
The incidence of VTE increases with age, ranging from less than 5 cases per 100,000 people in childhood to 500 cases per 100,000 people in the elderly.[1] Subjects who are more than 65 years of age are at three times higher risk for VTE compared to those who are 45-54 years old.[2]
Age
The incidence of VTE increases with age, ranging from less than 5 cases per 100,000 people in childhood to 500 cases per 100,000 people in the elderly.[1] Subjects who are more than 65 years of age are at three times higher risk for VTE compared to those who are 45-54 years old.[2]
Gender
Studies about differences in the incidence of VTE by gender have mixed results. While some reported a higher incidence of DVT among young females,[3] others reported it among either older females,[4] or in men.[2][5] In addition, the risk for DVT was reported to consistently increase with age across both genders.[2]
