A 58-year-old man was initially seen with fatigue and weight loss. Laboratory examination detected hypercalcemia, elevated 1,25-dihydroxycholecalciferol levels, low parathyroid hormone (PTH) concentrations, and subperiosteal bone resorption. The patient underwent subtotal parathyroidectomy for
No data documenting a possible depletion of bone mineral density in patients with chronic fatigue syndrome (CFS) are currently available. However, recent pathophysiological observations in CFS patients may have deleterious consequences on bone density. Firstly, the deregulation of the 2,5A
Bisphosphonates have the potential to reduce osteolysis, a phenomenon that has been postulated to play a key role in aseptic loosening of total joint replacements. Bisphosphonates may contribute to the in vivo longevity of total joint replacements. Some authors have suggested there are decreases in
A 36-yr-old woman began to suffer from headache, anorexia and general fatigue at 35 weeks' gestation. About 2 or 3 months after the delivery, fever, tachycardia and generalized musculoskeletal disorder appeared. Thereafter, they worsened rapidly, accompanied by a disturbance of consciousness and
OBJECTIVE
To investigate whether constitutional laxity of the connective tissues is more frequently present in adolescents with chronic fatigue syndrome (CFS) than in healthy controls. Increased joint hypermobility in patients with CFS has been previously described, as has lower blood pressure in
Osteocyte apoptosis appears to play a key role in the mechanism by which osteoclastic resorption activity targets bone for removal, because osteocyte apoptosis occurs in highly specific association with microdamage and subsequent remodeling after fatigue. However, beyond terminal deoxynucleotidyl
Load-induced fluid flow enhances molecular transport through bone tissue and relates to areas of bone resorption and apposition. Remodeling activity is highly coordinated and necessitates a means for cellular communication via intracellular and extracellular means. Osteocytes, osteoblasts, and
As a result of fatigue, bone sustains microdamage, which is then repaired by bone-remodeling processes. How osteoclastic activity is targeted at the removal of microdamaged regions of bone matrix is unknown. In the current studies, we tested the hypothesis that changes in osteocyte integrity,
The poly-ether-ether-ketone (PEEK) polymer is of great interest as an alternative to titanium in orthopedics because of its biocompatibility and low elastic modulus. This study evaluated the fatigue limits of PEEK and the effects of the low elastic modulus PEEK in relation to existing dental
Basically bisphosphonates are the agents that prevent the deterioration of bone structure due to suppressed bone remodeling although they are able to increase the thickness of cortical bone by suppressing bone resorption in the cortical surfaces. On the other hand, suppression of bone remodeling
A 16-year-old male was evaluated for a 1-month history of alveolar bone resorption, which had been treated with endodontics by a neighborhood dentist. Intraoral examination showed slight gingival swelling and teeth mobility. However, no tumor mass was seen. The panoramic image showed resorption of
BACKGROUND
Metastatic prostate cancer is characterized by the presence of osteoblastic bone metastases. Bone metastases account for most of the morbidity from this disease. Inhibition of osteoclast activity with the potent bisphosphonate zoledronic acid reduces skeletal complications and decreases
Fracture of dental implants is a rare phenomenon with severe clinical results. In this article, the literature is reviewed and various causative factors that may lead to fracture are presented. Galvanic activity has not been mentioned before as a possible cause for implant fracture, yet, it can
There is much individual variability in the clinical manifestations of hypocalcemia. The rapidly of the development of hypocalcemia will determine whether or not symptoms will be present. Signs and symptoms of hypocalcemia consisted of tetany (Chvostek's and Trousseau's signs), seizures, diminshed
OBJECTIVE
To evaluate the efficacy and safety of zoledronic acid in the treatment of bone pain in patients with bone metastasis from solid tumor or multiple myeloma.
METHODS
A randomized, double-blind, double-simulated and multi-center phase III clinical trail with pamidronate as control was
