Bone disease has reached near-epidemic proportions in America. Millions of people are suffering the often-crippling and devastating effects of diseases such as osteoporosis, a condition that results in a "demineralization" of the bone matrix, causing bones to become less dense over time and increasing the risk of fractures, especially of the spine, wrist and hip; and osteopenia (softening of th...

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic disorder in which a neoplasm causes systemic bone demineralization. Most cases are benign, but malignant neoplasms have been reported. The prognosis is good if diagnosis is made early and treatment is adequate. We present the case of a previously healthy 40-year-old man who presented with low back pain for the previous year. The initial ...

Introduction The main role of prolactin is associated mainly with lactogenesis but additionally it participates in several endocrinological and metabolic processes. level may be increased some antipsychotics such as risperidone, paliperidone, amisulpride increasing the risk Bone Mineral Mass (BMM) decrease leading to osteopenia osteoporosis. Objectives To determine loss BMM antipsychotic-relate...

The paralyzed musculoskeletal system retains a remarkable degree of plasticity after spinal cord injury (SCI). In response to reduced activity, muscle atrophies and shifts toward a fast-fatigable phenotype arising from numerous changes in histochemistry and metabolic enzymes. The loss of routine gravitational and muscular loads removes a critical stimulus for maintenance of bone mineral density...

We investigated the treatment effect of non-invasive infiltration on early caries caused by different degrees of enamel demineralization. Forty specimens of early enamel caries were prepared and divided into low and high demineralization groups. After treatment with non-invasive infiltration, the specimens were placed under cariogenic conditions. Color measurements were determined using a spect...

Enamel structure is of importance in demineralization. Differences in porosity in enamel effect the rate of demineralization, seen between permanent and deciduous teeth. Individual differences have been shown in the mean mineral concentration values in enamel, the role of this in demineralization is not thoroughly investigated. The aim of this study was to study variations of depths of artifici...
