[Relationship between number of involved coronary artery with some risk factors by angiography]

Despite the information regarding CAD risk factors, there isn't agreement between the relation of this risk factors and coronary artery diseases. This study was done for determination of related factors with vessels involved in coronary artery angiography. In this descriptive and analytical study, 2390 patients were selected via census sampling from Kosar Angiography center in the Golestan province. Data gathering form included data such as age, gender, body mass index [BMI], blood pressure, diabetes, smoking and opiates addiction history. Vessels involved were determined by angiography. Data analysis was done with one way ANOVAs and logistic regression using SPSS 16 soft ware. Mean and standard deviation of patient's age was 57.9 +/- 10. 58.2 percent of them were male. There were significant correlations between age, gender and BMI with numbers of vessels involved. Male gender [OR=1.329], hypertension [OR=1.25] and diabetes [OR=1.20] increased the probability of more than one vessels involvement. Regression analysis showed there were no significant correlations between age, BMI, smoking and opiates addiction history with more than one vessels involvement. Our finding confirmed that male gender, hypertension and diabetes are the main risk factors in involvement of more than one vessel

Clinical spectrum of 15 patients with HIV-related ocular involvement in Tehran / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To determine the frequency of HIV-related ocular involvement and to describe the characteristics of involvement in a special clinic in Tehran.METHODS: In this cross sectional study, 141 patients (125 male and 16 female, 282 eyes) of HIV-infected patients with various stages of HIV infection that were referred to Center of behavioral diseases were evaluated during a period of 7 months. Every patient had a complete profile including demographic data, method of HIV transmission, recent CD4 T cell lymphocyte count, serological studies for common sexual or blood-born viruses and toxoplasmosis, history of antiretroviral therapy, and associated systemic disease. RESULTS: A total of 141 patients were evaluated. HIV-related ocular involvement was detected in 15 patients (10.6%), including 3 mycobacterium tuberculosis-related choroiditis, 2 cytomegalovirus retinitis, 2 retinal toxoplasmosis, 2 herpes simplex virus-related lesions, 1 HIV-associated retinopathy, 1 herpes zoster ophthalmicus, 1 undetermined vitritis, and 3 cases of cranial nerve involvement including 2 cases of gaze palsy and 1 case of papilitis. In our study, mean CD4 T cell lymphocyte count was fewer in patients with ocular involvement than in patients without ocular involvement (204.7±123.8 vs 403.7±339.7, P=0.029), but there was no difference in other possible associated factors between two groups.lesions are the most common HIV-related ocular involvements in Tehran that is different from those of recent publications in developed countries.
