The purpose of this research is to establish a suitable mathematical model for the
study of epidemiology, showing the role of the epidemic threshold which cannot be
distinguished from the data for use by infectious disease experts and public health
.
There has been a growing interest in recent epidemiological models of epidemiology
because of their health and economic effects. Epidemiology (from a mathematical point of
view) is a section of general epidemiology that deals with mathematical modeling in
relation to the need to predict and spread infectious diseases.
Nonmelanoma skin cancer (NMSC) is the most common diagnosed malignancy. The NMSC consists of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
The purpose is to determine and evaluate the potential clinical or pathological changes of t
hese lesions in the last years. A group of archived cases of (NMSC) diagnosed in (1998-1999-2000) and in (2009-2010-2011) at a large university hospital in Lattakia (Alassad university hospital) was studied. The studied pathologic attributes included the histological type of BCC (nodular, superficial, infiltrating) and histological grade of SCC ( well, moderate, and poorly differentiated). Demographic features included age, sex and location.
The results are: Basal cell carcinoma was the predominant form of NMSC over the two study periods. BCC/SCC rate was higher than that reported before 9 years. The most common location is the head and neck. Most cases were diagnosed among patients aged (60-80) years. Both the nodular type of BCC and the well differentiated SCC had the higher rates. These rates have changed in time but the nodular BCC remained the most common type with slight decrease (P=0.31) followed by superficial (P=0.11) and then infiltrating (P=0.28). As for the well differentiated SCC, it remained the first with a significant increase in moderately differentiated SCC (P=0.009). The majority of patients were males except for the last years; the majority of SCC cases were females.
We retrospectively reviewed data of all patients who underwent study or surgery for Lung Cancer from (1997 to 2012) in the department of thoracic surgery at Alassad University Hospital in Damascus. There were 2029 patients with Lung cancer,1727 male
85,11% and 302 female 14,88%,87,53% of patients were smoking, and cough was the most common symptom about 70% of patients. There were 889 squamous cell carcinoma 43,81%, 702 adenocarcinoma 34,79%, 246 small cell carcinoma 12,12%,67 large cell carcinoma 3,3% and 66 carcinoid tumor 3,25%; the staging was 6,35% stageI,14,98% stageII,15,91% stage IIIA,29,02% stageIIIB,33,71% stage IV. Radical Surgery consisted of 621 formal lung resection 229 lobectomies 36,87%, 163 bilobectomies 26,2%, 158 pneumonectomy 25,44%,35 sleeve or bronchoplastic resection 5,63% ,36 partial resection 6,15%. The perioperative mortality was 3,05% and the overall 5 year survival was 22,9%. Our study resembles most of the studies made in the developing countries in the result that the rate of smoking and of lung cancer among women is fewer compared to the International rate. It also resembles most of the European countries in the result that squamous cell carcinoma is the most common pathological pattern, and the size of pulmonary resection is bigger than that in the developed countries where they have earlier diagnosis. Moreover, the rate of the sleeve resection surgery along with the rate of mortality resemble that of the International centers.
The aim of this research is to study statistically erysipelas cases and its precipitating factors and also to determine the possibility of considering intramuscular injection of lincomycin as an effective treatment of uncomplicated erysipelas instead
of intravenous penicillin G.
60 cases of erysipelas were studied and evaluated. There was no significant relation to age, sex and site of infection. The most affected sites were lower limbs, then face, and upper limbs.
The most important risk factors were fungal intertrigo, vascular impairment and finally diabetes mellitus.
The response to lincomycin treatment was excellent in 71.71%, intermediate in 23.91% of patients, while there was no response in only 4.34% of cases.
Cysts are more frequent in jaws comparing to other body bones, although their
treatment is simple and depends on surgical approach as a first choice, still they are important due to
their clinical complication.
The aim of this retrospective study
is to determine the percentage of radicular, dentigerous, odontogenic
keratocysts and non-odontogenic cysts percentage in Damascus, Syria, and comparing these results with
previously recorded records from other countries.
W.H.O has defined sudden unexpected death as the death that
occurs within 24 hours from the onset of the acute symptoms that preceded
death. The forensic pathologists define it as, any death which occurs
suddenly and unexpectedly, usually from nat
ural causes, in persons who
were apparently in good health and in circumstances that raise suspicion
and surprise. The performance of a complete autopsy in such deaths is
mandatory. The aim of autopsy is to deny any traumatic or poisonous
causes for death, and to find the direct pathological causes of the death. The
aim of this study was to describe the epidemiology of this type of death in
Babel governorate, and to compare our results with those obtained by other
studies.
Luteoviruses were recognized as a major cause of yellowing, leaf rolling and
stunting in chickpea (Cicer arietinum L.) in Syria. Aphid population dynamics
in two consecutive seasons (١٩٨٩/٩٠ and ١٩٩٠/٩١) showed a peak in April
followed by high lev
els of virus incidence and ranged between ٤ – ٧٨,٤ %.
Different sowing dates of four chickpea varieties (local chickpea, Ghab١,
Ghab٢ and Ghab٣) showed that early planting lead to disease escape, by
avoiding early infection. The yield average of the four chickpea varieties was
increased by ٢٦٠% in the first season and ١٤٠٪ in the second, when the crop
was planted early. Weeds have been studied as a potential over-wintering hosts.
A range of weed species mostly with yellows symptoms similar to those caused
by luteoviruses were collected from the field trial and tested. They proved to
host aphid vectors as well as luteoviruses.
