The incidence of sexually transmitted diseases(STDs) increased from 26. 04 per 100 000 in 1987 to 104. 81 per 100 000 in 1993 in selected areas of the country.

The incidence of sexually transmitted diseases(STDs) increased from 26. 04 per 100 000 in 1987 to 104. 81 per 100 000 in 1993 in selected areas of the country. Gonorrhea is by far the most common STD but its constituent ratio declined because of a rapid increase of nongonococcal uretheritis and genital warts during most recent years. The incidence of syphilis is relatively low and cases of congenital infection are noted. The wide spread of resistant Neisseria gonorrhoeae infection gives a challenge to the therapeutical and control strategies of STDs. Sexually transmitted Chlamydia trachomatis infections, an important cause of urethritis. cervicitis and pelvic inflammatory disease. is becoming common in our country. Attention has been drawn on viral hepatitis in their means of transmission by sexually behaviors, and also, on the homosexuals, assumed to be the high risk group to catch STDs. Coordinated national efforts to control STDs in China have been taken. 展开更多

AIM:To study the clinical and epidemiological features of patients with clonorchiasis so as to provide scientific evidences for the diagnosis and prevention of clonorchiasis. METHODS:Stools from 282 subjects suspected of having clonorchiasis were examined for helminth eggs with modified Kato's thick smear and sedimentation methods,and their sera were tested for HAV-DNA,HBV-DNA,HCV-RNA,HDV- RNA and HEV-RNA with polymerase chain reaction (PCR). Clinical symptoms of patients with clonorchiasis only were analyzed,and their blood samples were tested for circulating antigen (CAg) with Dot-ELISA,esoinophilic granulocyte count, and alanine aminotransferase (ALT).Meanwhile,they were asked to provide data of occupation,eating habit,hygienic habit and knowledge of donorchiasis.In addition,the ecosystem of the environment in epidemic areas was surveyed. RESULTS:Among the 282 patients,61 (21.43%) were infected with clonorchis sinensis only,97 (34.64%) were co-infected with clonorchis sinensis and other pathogens, 92 (32.86%) were infected with hepatitis virus only and 31 (11.07%) neither with clonorchis sinensis nor hepatitis virus. Among the 61 patients with clonorchiasis only,there were 14 (22.95%) subjects with discomfort over hepatic region or epigasfrium,12 (19.67%) with general malaise or discomfort and inertia in total body,6 (9.84%) with anorexia,indigestion and nausea,4 (6.56%) with fever,dizziness and headache (6.56%),and 25 (40.98%) without any symptoms;sixty one (100%) with CAg (+),98.33% (59160) with eosinophilic granulocytes increased and 65.00% (39/60) with ALT increased.B-mode ultrasonography revealed 61 cases with dilated and thickened walls of intrahepatic bile duct,and blurred patchy echo acoustic image in liver.Twenty-six cases had stones in the bile duct,39 cases had slightly enlarged liver with diffuse coarse spots in liver parenchyma.Twenty cases had enlarged gallbladder with thickened coarse wall and image of floating plagues,9 cases had slightly enlarged spleen.By analysis of epidemiological data,we found that the ecologic environment was favorable for the epidemiology of clonorchiasis.Most patients with clonorchiasis were lack of knowledge about the disease.Their living environment, hygienic habits,eating habits and their occupations were the related factors that caused the prevalence of the disease. CONCLUSION:The clinical symptoms of clonorchiasis are non-specific,and the main evidences for diagnosis of clonorchiasis should be provided by etiologic examination, B-mode ultrasonography and clinical history.The infection of clonorchis sinensis is related to occupations,bad eating habits and lack of knowledge about prevention of the disease. 展开更多

Risk factors for genitourinary Chlamydia trachomatis (Ct) infection were investigated using an STD elative risk factor questionnaire among 176 patients and theirregular sexual partners. Twenty-four independent variableswere selected for analysis, nine of which were confirmed asfactors associated with C. trachomatis. Four of the nine factorswere significantly correlated to infection using a multifactorialunconditional logistic regression model which included: levelof education (odds ratios [ORs]: 2.144 for below junior middleschool), number of sexual partners (ORs: 4.503 for≥5),number of regular partner's sexual partner (ORs: 16.333 for≥5), STD history of regular partner (ORs: 18.417 for theirSTD history). These data demonstrate that regular partner'ssexual behaviors are also an important risk factor for Ctinfection among STD clinic clients. 展开更多

The lack of familiarity of project management standards is one of the common risks in the construction industry in Egypt. The main aim of this paper is to identify the most significant risk factors affecting highway construction project in Egypt to decrease the likelihood and impact of those risks. The research method starts with extensive literature review to provide a prime risk factors list which was also augmented to expertise to reach final risk factor list which contains all risks that may be faced during highway construction. Subsequently, a set of 12 risk groups consisting of 73 risks was selected and a questionnaire survey was conducted to determine the likelihood and consequences of the identified risks. Later, a software application was developed using MATLAB to facilitate risk evaluation of highways projects. Results indicated that the risk factors arise from owner side is one of the most common risk factors in the construction industry in Egypt as the owner in the majority of construction project in Egypt is the governmental sector, however, the overall project risk of highway construction projects in Egypt is considered as at a medium level. 展开更多
