BACKGROUND Chronic recurrent multifocal osteomyelitis (CRMO), also known as chronic nonbacterial osteomyelitis, is a rare, noninfectious inflammatory disorder that causes multifocal bone lesions with swelling and pain. Lytic and sclerotic bone lesions could be found on X-ray. Short tau inversion recovery magnetic resonance imaging (STIR MRI) shows bone marrow oedema, bone expansion, lytic areas...

Cancer pain, particularly bone cancer pain, affects the quality of life of cancer patients, and current treatments are limited. Interleukin (IL)-33, a new member of the IL-1 super family, has been reported to be involved in the modulation of inflammatory pain. However, studies focused on its role in the modulation of cancer pain have been rare. The present study was designed to investigate whet...

BACKGROUND Bone metastases occur frequently in advanced breast, lung, and prostate cancer, with approximately 70% of patients affected. Pain is a major symptom of bone metastases, and current treatments may be inadequate or have unacceptable side effects. The mechanisms that drive cancer-induced bone pain are not fully understood; however, it is known that there is sensitization of both periphe...

Cancer pain is not a single entity but a complex pain state involving different pain syndromes, with inflammatory, neuropathic, compressive, and ischaemic mechanisms. Current therapeutic regimens are based largely on opioids, although opioid treatment can lead to many side effects. Studies using animal models of cancer pain are aimed at understanding cancer pain and developing novel therapies. ...

PURPOSE Postmenopausal osteoporosis causes bone fracture as well as pain, physical, psychological and socially adverse effects, which affects a patient's quality of life (QOL). The effect of alendronate on QOL was investigated compared with that of alfacalcidol in post-menopausal osteoporotic women. PATIENTS AND METHODS A total of 44 postmenopausal osteoporotic women (mean age 69.8 years) wit...

BACKGROUND cAMP response element binding protein (CREB)-dependent gene expression plays an important role in central sensitization. CREB-regulated transcription coactivator 1 (CRTC1) dramatically increases CREB-mediated transcriptional activity. Brain-derived neurotrophic factor, N-methyl-d-aspartate receptor subunit 2B, and miRNA-212/132, which are highly CREB responsive, function downstream f...

intraosseous ganglia can affect the carpal bones of the hand and must be considered in the differential diagnosis of wrist pain. a 38-year-old female presented with a 14-month history of left wrist pain and a radiolucent cystic lesion was seen computed tomography (ct) scanning. characteristic radiographic findings of a cyst in association with a fine sclerotic rim was apparent. we report an unu...

Accumulating evidence suggests that activation of spinal microglia contributes to the development of inflammatory and neuropathic pain. However, the role of spinal microglia in the maintenance of chronic pain remains controversial. Bone cancer pain shares features of inflammatory and neuropathic pain, but the temporal activation of microglia and astrocytes in this model is not well defined. Her...

Strontium-89 (Sr), a bone-seeking radiopharmaceutical, has been used successfully in recent trials to palliate bone pain secondary to metastatic disease. The use of this beta emitter in systemic radionuclide therapy should become an integral part in the management of many patients with metastatic disease to the bone. Intravenous Sr may be used in conjunction with standard chemotherapy and exter...

In prior studies, models of inflammatory pain were produced through injecting complete Freund's adjuvant (CFA) or capsaicin directly into either the deep somatic tissue or the animal's hind paw. In contrast, bone cancer-induced pain (BCIP) was simulated through injecting tumor cells into the cavity of the femur or the tibia. It has been reported that, due to differences in afferent innervation,...
