Bone metastasis occurs as a result of a complex pathophysiologic process between host and tumor cells leading to cellular invasion, migration adhesion, and stimulation of osteoclastic and osteoblastic activity. The process is mediated by parathyroid hormones, cytokines, and tumor-derived factors. Several sequelae occur as a result of osseous metastases and resulting bone pain can lead to signif...

PURPOSE This article reviews a few of the commonly used types of vascularized osseous free flaps in maxillofacial reconstruction, which still represents the gold standard of restoration. We also discuss the developing concepts in maxillofacial reconstruction. RECENT FINDINGS Most of the literature reconfirms the established patterns of reconstruction with the aid of vascularized osseous free ...

Bone scan is a well-established imaging modality in detection of osseous metastasis. However, its sensitivity decreases at evaluating lytic osseous metastasis in such entity as hepatocellular carcinoma (HCC). Increasingly, Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) with dual-time points imaging is utilized in detection of osseous metastasis from hepatocellular car...

OBJECTIVE To evaluate the occurrence of temporomandibular joint disk displacement and its correlation with pain and osseous abnormalities using magnetic resonance imaging (MRI) in patients under 21 years of age. STUDY DESIGN MRI images in open- and closed-mouth positions from 102 patients, under 21 years of age (mean age 17 years), were studied retrospectively. Patients were divided into six ...

OBJECTIVES Here, we report a case of simultaneous osseous metaplasia nodules of the submucosa and mesosalpinx after a first trimester abortion. CASE PRESENTATION A 36-year-old woman presented to the Women's Hospital, School of Medicine, Zhejiang University with vaginal bleeding and infertility resulting from osseous metaplasia nodules of the submucosa and mesosalpinx after a first trimester a...

The osseous pelvis is a well-recognized site of origin of numerous primary and secondary musculoskeletal tumors. The radiologic evaluation of a pelvic lesion often begins with the plain film and proceeds to computed tomography (CT), or magnetic resonance imaging (MRI) and possibly biopsy. Each of these modalities, with inherent advantages and disadvantages, has a role in the workup of pelvic os...

The topic of this case report is a rare subconjuctival osseous choristoma that corresponded to the left lateral sunconjunctiva and canthus. A 20-year-old man was asymptomatic when he arrived for the examination. His full ophthalmic examination was normal. Orbital computerized tomography was concordant with osseous lesion. Osseous choristomas are the rarest forms of ocular choristomas, they are ...

The Pacific Decadal Oscillation (PDO) is a large-scale climatic phenomenon modulating ocean-atmosphere variability on decadal time scales. While precipitation and river flow variability in the Great Barrier Reef (GBR) catchments are sensitive to PDO phases, the extent to which the PDO influences coral reefs is poorly understood. Here, six Porites coral cores were used to produce a composite rec...
