Abstract:
Pseudohypoparathyroidism is characterized by a resistance to parathormone, with variable phenotypical and biochemical manifestations. Its diagnosis is difficult. We report a 28 year old male presenting with a hypokalemic periodic paralysis. His serum PTH was elevated to 1,343 and 1,101 pg/ml with concomitant hypocalcemia of 7.9 and 6.7 mg/dl. Twenty four hour urinary calcium and serum 25 hydroxy vitamin D were normal. Bone mineral density was normal. The patient was managed with calcitriol in doses of 1 to 2 microg/d, associated to calcium 2 g/day. Serum calcium levels and PTH normalized after two months and six months of treatment respectively.

Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
