Perfect localization of hyperactive parathyroid glands is useful to minimize operation time, incision and reduce patient morbidity. 52 patients with hyperparathyroidism were investigated, 14 with primary and 38 with secondary hyperparathyroidism foll
owing renal failure. Surgery has been done on 36 patients (14 with primary and 22 with secondary hyperparathyroidism). Sensitivity of 99mTc-tetrofosmin scintigraphy was estimated after surgical removal of Hyperfunctioning glands and compared with that of ultrasound and magnetic resonance imaging. The sensitivity of 99mTc-scintigraphy (79,5%) exceeded the sensitivity of ultrasound (68,2%) and magnetic resonance imaging (71,6%). Parathyroid hormone (P.T.H.) and calcium levels in serum were compared with positive 99mTc-tetrofosmin Scintigraphy. Results demonstrated correlation between positive 99mTc-tetrofosmin scintigraphy and parathyroid hormone levels with significant statistical difference of P < 0.001 and all patients with primary hyperparathyroidism with P.T.H. levels of 195 pg/ml or more were scintigraphically positives. All patients with secondary hyperparathyroidism with P.T.H. levels of 1200 or more were positives. No correlation was detected between calcium levels and positivity or negativity of scintigraphic results.
The study is carried on 65 pregnant patients attending the outpatient clinics and
inpatient department of Obstetrics and Gynecology of Al Assad University Hospital from
February- 2013 until February- 2014. They were divided to three groups. The fir
st is
preterm labor with intact membranes (25 patients). The second is PROM (20 patients). The
third one is control group (20 patients). All of them were submitted to ultrasonography to
find cervical changes (cervical canal length and diameter of internal os in order to predict
preterm delivery. Cervical canal length has a sensitivity of 91.43%, a specificity of 100%,
a positive predictive value of 100%, a negative predictive value of 76.92%, and a relative
risk (95% CI) of 4.33 (1.61-11.69) among patients with short cervical canal length and
those with normal cervix.
Diameter of internal os as a predictor of preterm delivery has a sensitivity of 60%, a
specificity of 60%, a positive predictive value of 84%, a negative predictive value of 30%,
and a relative risk (95% CI) of 1.2 (0.86–1.68).
Most of Syrian pregnant women do not remember their LMP exactly, so that if
there is another correct way (like CRL measurement by ultrasound), It may improve the obstetric
management in clinical practice.
To compares between regular last menstrual
period (LMP) and ultrasonographic crown–rump length
(CRL) measurements in predicting the delivery dates (EDD) in a Syrian population.
Fetus images produced by 2D ultrasound devices are ambiguous and lack precision. This led to the need
for offering a 3D visualization of the fetus, which allows visualizing width, height, and angle, in order to
get additional information about the
fetus, and detect fetus abnormalities.
We explain in this paper our method in producing 3D models of the fetus from 2D images using a
computer system without the need for changing the 2D imaging devices, and without using position
sensors.
Our method is based on passing the probe over the pregnant woman's abdomen and make a manual scan
for the entire body of the fetus from top of the head till the bottom of his feet, then it saves this scan as a
video clip then send, it to the computer which segments the video into multiple images which are saved and
later processed using digital processing principles of images. Then these processed images are
reconstructed to produce the volume matrix and then display it in a 3D form using 3D model construction
methods.
We applied our software on various fetuses of different ages and got volume images which are considered
good in comparison with the images offered by currently available systems and devices. The precision of
the images we got, differs according to the change in fetus pose, amniotic liquid, and fetus size, The
obstetrician or gynecologist can retrieve more precise details by changing the angle and displaying volume
images of certain part of the fetus body.
Most of Syrian pregnant women do not remember their LMP exactly, so that if
there is another correct way (like BPD measurement by ultrasound), It may improve the obstetric
management in clinical practice.
To compare between regular last menstrual
period (LMP) and ultrasonographic Bi-Parietal Diameter
(BPD) measurements in predicting delivery dates(EDD) in a Syrian population.
Total Polyphenol was studied in olive leaves collected from Lattakia area
(AlQurdaha zone), where Phenolic compounds were extracted from dry Olive leaves by
using two extraction methods: maceration and Ultrasonic Device. By the both two methods
a
study was carried out on the extraction solvent concentration effect where the extraction
was done by using the mixture of Ethanol-Water with different percentages (60,70,80
%). As well, The extraction temperature effect was studied at the both methods at (20,30,
40°C); in addition to the study of the extraction time effect.
At the method of Maceration Extraction, the total polyphenols amount was studied in
dry olive leaves after extraction during different times (24,48,72 h). While at the Ultrasonic
Extraction the times were (10,20,30 min).
The study showed that the highest amount of phenolic compounds were existed in
dry olive leaves which were extracted by Ultrasonic Waves with the concentration of the
solvent ethanol-water 80%, temperature of 40°C, and with an extraction time of 20min.
Vibration of Ultrasonic has used for scaling
and periodontal curettage, it is also has used for metal crown and
metal-ceramic crown removal, subsequently, using the tips whether for
scaling or removing crown, they will be in direct contact with th
is crown,
This research aimed to evaluate the surface of metal-ceramic crown
after exposure to Vibration of Ultrasonic tips.
