The parathyroid glands secrete parathyroid hormone (PTH), which is important for maintaining calcium homeostasis. Parathyroid gland hyperplasia and subsequent hyperparathyroidism can occur secondary to chronic renal failure in dogs, resulting in significant alterations in calcium metabolism. Renal secondary hyperparathyroidism is a complex, multifactorial syndrome that involves changes in circu...

BACKGROUND In patients with hyperparathyroidism, parathyroidectomy is the only curative therapy. Anaesthetic management differs function of etiology (primary vs. secondary or tertiary hyperparathyroidism) and surgical technique (minimally invasive or classic parathyroidectomy). OBJECTIVES To evaluate peri-operative management (focusing on hemodynamic changes, cardiac arrhythmias and patients'...

The patient is a seventheen years old girl, with severe pain and swelling in right maxillary sinus region and facial deformity from two weeks prior to referring. CT scan demonstrated a large tumoral mass in right maxillary sinus extended to petereigomaxillary fossa, orbital floor, lacrimal system and nasoethmoid region. Hard palate had been destroyed and bulged in to the oral cavity. Tumor was ...

introduction: radio-guided parathyroid surgery along with other minimally invasive surgeries constitutes the main surgical treatment procedures for different kinds of hyperparathyroidism.  in this article we have reported our experience of radio-guided parathyroid surgery using tc-99m sestamibi. methods: ten patients with hyperparathyroidism included in our study. twenty mci of tc-99m sestamibi...

A case of malignant transformation in established secondary hyperparathyroidism presenting as tertiary hyperparathyroidism is reported. Although rare, this occurrence has important medical and surgical implications.

Hyperparathyroidism is due to increased activity of the parathyroid glands, either from an intrinsic abnormal change altering excretion of parathyroid hormone (primary or tertiary hyperparathyroidism) or from an extrinsic abnormal change affecting calcium homoeostasis stimulating production of parathyroid hormone (secondary hyperparathyroidism). Primary hyperparathyroidism is the third most com...

Naturally occurring secondary nutritional hyperparathyroidism is described in the nestlings of two colonies of cattle egrets (Bubulcus ibis) from Central Texas (Bryan and San Antonio, Texas, USA). Nestlings from a third colony (Waco, Texas, USA) were collected in a subsequent year for comparison. Birds from the first two colonies consistently had severe osteopenia and associated curving deformi...

INTRODUCTION Osteoporosis is characterized by a decrease in bone mass and a change in bone microarchitecture. This causes skeletal fragility and may result in fractures. Fractures of the femur neck (FM) are frequent and have major consequences in terms of morbidity and mortality in elderly subjects. We carried out a cross-sectional study to evaluate bone and nutritional status in an elderly pop...

brown tumors may occur secondary to hyperparathyroidism in patients with chronic renal failure (ckd). they are increasingly rare because hyperparathyroidism in now diagnosed and treated at an early stage. we report 67-year-old man who had been on hemodialysis for crf for over 3 years, who presented with back pain over the thoracolumbar junction from 2 years ago and because of pain he could not ...

Classical nutritional vitamin D-lack rickets is practically non-existent in countries where child care and treatment are available, but it is occasionally present especially in mentally subnormal children (C. E. Dent, 1961, personal communication). This could be due to the much more serious feeding problem they present, or there may be a neuro-biochemical defect due to brain damage, or a combin...
