Systemic mastocytosis (SM) is a rare malignant neoplasia,
which can create bone complications. The most frequent of those
is secondary osteoporosis, sometimes responsible for fractures,
especially of the rachis. We report the case of a 53 year-old
woman with 3 non-traumatic lombar fractures, leading to the
diagnosis of SM, after bone marrow trephine biopsy. We describe
the different types of bone involvement in MS, their
physiopathology, their diagnosis and treatment, with help of a
bibliographic review.
Background& Objective: The reduction of alveolar crestal bone density is one of the earlier signs of periimplant
disease and precedes the loss of height of the alveolar crest, because of that early detection of the
small changes in density is impor
tant and lead to the early onset of treatment and increases its success's
percentage.
This study aimed to evaluate the ability of the direct conventional digital method in detection of density
changes around dental implants by the mean value of the gray level of the histogram of the selected area
comparing with radiographic subtraction method.
Isthe radiographic bone density bigger at the area of implant orof tooth?and is
thisdensity changingafter one year of function betweentooth and implant connected with bridge? the aim
of the studyis tostudythe changing of radiographic bone density d
uring one year of radial observation of
the bone area around the tooth and implant connected with bridge with 3 units(rigid or non-rigid
connection) depending on digital periapical radiographic.
To report the results of evaluation of the color digital subtraction technique in
assessing quality and quantity peri-implant bone changes in dental x-ray imaging.
Is the changing of biomechanics between the tooth and implant affected on the
homogeneity of bone surrounding the tooth and implant connected with fixed prosthesis. the aim of the
study is to study the connection of bone area in both sides (mesial&distal) of tooth & implant connected
with bridge(in the form of rigid or non-rigid connection) during one year of radial observation of
radiographic bone density.
This study aimed to define the levels of vitamin D3 in postmenopausal women and
their relation with bone mineral density (BMD). The study included 83 women (48-81 year)
who visited the Department of radiology of Al Asad hospital in Lattakia. Bone m
ineral density of
the lumbar spine (L1–L4) and total hip was measured by dual-energy X-ray absorptiometry (DXA).
Blood samples were collected to assay 25(OH)D3 and Ca.
The mean level of 25(OH)D3 was 18.87 ng/ml (6.96 SD) and the prevalence of
vitamin D3 difficiency { 25(OH)D3<20 ng/ml} was 64%. No correlation was found
between BMD and 25(OH)D3 levels [P value>0.05], and no correlation was found between
25(OH)D3 and age or body mass index (IMD). We found a strong correlation between
25(OH)D3 and duration of sun exposure (P value = 0.01). Conclusion: Hypovitaminosis D3
is very common among postmenopausal women. Vitamin D33 status may not be an
important determinant of bone health.
