The features of Hypertrophic pulmunary osteoarthropathy (HPOA) on radionuclide bone scintigraphy have been well described in case reports and small series of patients. The aim of this study was to investigate prospectively the prevalence and distribution of HPOA in a large series of patients with carcinoma of the lung. Two hundred and eleven patients aged 31-89 years (average age 66 years...

The adult skeleton undergoes bone remodeling that consists of bone formation by osteoblasts and bone resorption by osteoclasts. When the amount of bone resorbed is greater than the amount of new bone formed, low bone mass results, putting individuals at increased risk for osteoporosis and osteoporotic bone fracture. Nitrogenous bisphosphonates (NBPs) are the most common first line treatment for...

objective: to assess the stability changes as a reflection of early healing around roughened- surface implants in human by resonance frequency analysis (rfa). materials and methods: one hundred and fifty one iti sla implants were placed in either maxilla or mandible of 68 patients. bone type was classified into 4 groups according to lekholm and zarb index. rfa was used for direct implant stabil...

In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

Small cell carcinoma has been reported to arise in many extrathoracic sites. However, such tumours arising from bone have not been previously described. We report what we believe is the first reported case of extrapulmonary small cell carcinoma of bone. The tumour arose from the fifth dorsal vertebra in a 60 year old woman. The patient was treated with local radiotherapy and combination chemoth...

Introduction: The aim of this research was to study the effect of a 6-week supplemented diet on increasing bone density by measuring calcium, phosphorus and bone mineral density (BMD) in male rats. Materials and methods: In this experimental study, 24 Wistar male rats, aged between 15 and 20 days, were selected. The rats were randomly divided into 3 groups: immune system supplement (ISS), ...

Bone islands are usually considered benign, stable, nonprogressive lesions, radiographically characterized by an ovoid, round, or oblong homogeneously dense and sclerotic focus in the spongiosa, with a preference for the long bones and the pelvis. Benign solitary bone islands are usually believed to be asymptomatic, with no necessity for treatment. Symptomatic bone islands reported in the liter...
