introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...

background: to investigate the relationship between renal stone formation and osteoporosis. methods: eight hundred thirty healthy subjects aged between 20 and 76 years were randomly selected from 50 clusters to take part in the study. of these, 68 (8.2%) had a previous history of renal stone disease. all participants underwent clinical exami nation and bone mineral densitometry of the lumbar sp...

bone scanning using the 99mtc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. the bone scan is one of the most commonly requested procedure in most nuclear medicine department. the images show areas of increased and decrease...

nonfunctional adrenocortical carcinoma is an extremely rare malignant tumor in children. unlike the functional tumor which is detected early due to its hormonal presentation, nonfunctional tumor is detected at a later stage. here we report a case of a 10 year old girl who presented with abdominal mass and symptoms of short duration. no hypertension and cushingoid features were seen. serum alpha...

conclusions using 3d ct scan to produce a prototype and reconstruct the mandible with a custom-made ti-mesh tray was useful. patient was followed up for 14 months. mandibular deviation was largely corrected. there was no complication in the donor site. no sign of extra or intra oral fistula, dehiscence or infection was detected. ti-mesh technique has three major advantages over other methods: i...

pathologic fractures of the jaw are usually associated with aggressive, destructive lesions or malignant lesions of the jaws. aneurysmal bone cysts (abc) of the jaws are benign lesions which normally do not cause destruction to such an extent. this article reports a relatively aggressive abc of the mandible in a 19 year-old male which destroyed the buccal and lingual cortices as well as the inf...

in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...

Linear measurement includes the measurement of lengths, diameters, heights and thickness. The basic principle of linear measurement (mechanical type) is that of comparison with standard dimensions on a suitably engraved instrument or device. Linear measuring instruments are categorized depending upon their accuracy. The two categories are non-precision instruments and precision instruments. Non...
