This study was executed at Al Assad hospital, Lattakia . is a retrospective study of ovarian mass patients who had been accepted in the department of gynecology during the period between 1/1/2009 and 31/12/2013 .The aim was to study age distribution
of benign and malignant tumors , and to study the relation between Ca125 and pre/postmenopausal benign and malignant tumors.
The study included 148 patients . The patients' ages ranged between 13-78 years , and the majority of benign tumors occurred in the age group 21- 40 years and the majority of malignant tumors occurred in the age group 51- 60 years .
The commonest tumors were epithelial in origin followed by the germ cell tumors followed by sex cord stromal tumors and metastatic tumors.
In benign tumorsCa125>=35u/ml was more frequently with endometriosis followed by serous tumors . and in malignant tumors was more frequently with serous tumors followed by mucinous tumors.
The highest sensitivity of ca125 level was in prediction postmenopausal benign tumors but with low specificity followed by prediction postmenopausal malignant tumors with high specificity.
The quality of the test was higher in postmenopausal benign/malignant tumors compared to premenopausal tumors
To identefi the Bacterials agents in Meningitis resulting from basal skull
Fractures, The antibiotics sensitivity, and The benefit of pneumo 23 vaccine to prevent the occurrence of
meningitis in these cases.
The effect of thermal noise and shot noise on the receiver sensitivity in a digital
optical communication system will be studied and analyzed. Also, the positive and
negative effects of Parameters on the receiver sensitivity will be highlighted. Th
e
programming tools (MATLAB) is used to study the relationship between the receiver
sensitivity and bit rate. It showed that the shot-noise-limited receiver sensitivity is much
better than the thermal -noise-limited receiver sensitivity with best 30dB. The study also
provided an explanation for the preference of optical detector (APD) compared to that in
(PIN) optical detector from sensitivity side due to its internal gain, this can be achieved
when the thermal noise is dominant. However, the preference of optical detector(PIN) will
be better in case of shot noise is dominant.
Analyzed results show that there is a significant improvement in the shot-noiselimited
receiver sensitivity for high quantum efficiency and high wavelength. However, the
sensitivity is deteriorated to get a lower error rate. The thermal -noise-limited receiver
sensitivity showed an improving by increasing the responsivity and the load resistance.
However, it decreases by increasing the number of noise and the error rate.
Cutaneous leishmaniasis is still one of the most important health
problems in Syria which witnessed increasing the numbers of
cutnaneous leishmaniasis reported, especially during the crisis ,Also
the direct microscopic examination of Giemsa-stained scrapings of
lesions is still a suitable method for diagnosis of cutaneous
leishmaniasis due to the low cost, ease of performance, speed, and
lack of a need for sophisticated laboratory equipment.
We performed this study aimed to compare the sensitivity of
parasite detection by microscopic examination in samples collected
by conventional technique and samples collected after local
anesthetic with lidocaine and adrenaline of the same lesions in
patients with suspected leishmaniasis.
