BSTRACT: BACKGROUND: Acne vulgaris(AV)is chronic inflammatory disease of pilosebaceous unit of young people. Patients with acne with or with out scarring might differ in regard to their immunological background from those free from acne. OBJECTIVES: To evaluate the problem of facial AV especially patients with scarring and to determine the frequency of associated skin diseases and to be compared with acne free control. METHODS: A cross sectional randomized controlled epidemiological study was conducted from Oct.2005-Oct. 2006.Three hundred students from Basra University; 132 (44%) males and 168 (56%) females were enrolled, their ages ranged from 18-25 (20.9±1.8) years. They were divided into: Group A those free from acne (98 individuals),Group B with non scarring facial AV (96 patients), and Group C with scarring facial AV (106 patients). History and examination were done for their acne, scarring acne and associated skin diseases. Allen and Smith grading system for AV were used, and a new invented multiparametric scoring system for scarring acne was applied. RESULTS: AV was in 98(73.24%) males and 104 (61.9%) females. Scarring was 54 (50.95%) males and 52 (49.05%) females. Greasy skin was the most common type among Group B 67 (69.8%) versus 39 (39.8%) among Group A(P=0.000029) and was more common among Group C 84(79.2%) (P=0.00000001).Family history of AV was nearly similar in A and B Groups 55(57.29%) and 56 (52.83%) respectively, while in Group A was 39 (39.79%). Family history of scarring acne was in 35(33.02 %) of Group C, 16 (16.66 %) of Group B, and 3 (3.1%) in Group A; (P=0.00000017). The age of onset was similar in A and B Groups between 15-16 years. Majority of patients in Group B had non inflammatory type or mild inflammatory (papular) 65 (67.8%) patients, most of case were mild and moderate 86 (89.58%) patients, while high percent in Group C had inflammatory type 95 (89.62%), and more than half of them had severe and very severe types upon grading 56 (52.8%). The aggravating factors were similar in A and B Groups with stress and hot weather being the leading aggravating factors. Squeezing and digging habit was in 53 (50%) in Group C versus 23 (23.95%) in Group B (P=0.00024). In most cases of scarring acne, scarring was mild and moderate 85 (80.19%), and the most common type scars was the flat hyperpigmented [50 (47.17%) and 66 (62.26%) respectively].The most common effect of scarring acne on psyche was mild discomfort and mild dysmorphophobia 75 (70.75%).Associated skin diseases were more common among Group A 31 (31. 63%) than among Group B 22 (22.91%) and least common among Group C 14 (13.20%) (P=0.0067) and they were mainly dermatitis and skin infections. CONCLUSION: AV might reflect the immunological status especially among patients with scarring. The frequency of skin diseases was much less among patients with scarring acne
Human skin detection, which usually performed before image processing, is the method of discovering skin-colored pixels and regions that may be of human faces or limbs in videos or photos. Many computer vision approaches have been developed for skin detection. A skin detector usually transforms a given pixel into a suitable color space and then uses a skin classifier to mark the pixel as a skin or a non-skin pixel. A skin classifier explains the decision boundary of the class of a skin color in the color space based on skin-colored pixels. The purpose of this research is to build a skin detection system that will distinguish between skin and non-skin pixels in colored still pictures. This performed by introducing a metric that measu

Objective:This study was established to investigate theof effect of yellow sap and gel of Aloe vera on skin of the rabbits which infected with T.verrucosum. Methods : Twelveskin biopsy were taken from rabbits for histopathological study to know the the effects of the T.verrucosumand treated with yellow sap and gel. Results : the results of histopathological study of effect of yellow sap and gel of Aloe vera on skin of the rabbits which infected with T.verrucosum showed the concentration of the gel of aloe vera at 75% was more effected to treat the infective area of skin with T.verrucos

Show MoreThis study designed to evaluate the relationship between the Matrix metalloproteinase -9(MMP-9), soluble Vascular endothelial cadherin(VE-CAD)and Chlamydia pneumonia infection in cardiovascular diseases patients. All blood sample were subjected for molecular detection of C.pneumoniae by using conventional polymerase chain reaction (PCR) depending on 16S rRNA while the level of serum MMP-9, VE-CAD measured by enzyme linked immunosorbent assay (ELISA). Seventy patients who suffering from cardiovascular diseases (angina, myocardial infraction and atherosclerosis) aged between 33-86 years have been investigated and compared to twenty of apparently healthy individuals as control group. Twenty six samples (37.14%) revealed positive results for C.
... Show MoreAtherosclerotic cardiovascular disease (ACVD) is an inflammatory disease of the coronary arteries associated with atheroma formation, which can cause disability and often death. Periodontitis is ranked as the sixth most prevalent disease affecting humans affecting 740 million people worldwide. In the last few decades, researchers have focused on the effect of periodontal disease (PD) on cardiovascular disease. The aim of this review was to investigate the association between these two diseases. PD is a potential risk factor that may initiate the development, maturation, and instability of atheroma in the arteries. Two mechanisms were proposed to explain such association, either periodontal pathogens directly invade bloodstream or in

Turmericcurcumin has proved its efficiencies a coloring, flavoring agent and has been traditionally used in medicine, exhibiting remarkable anti-inflammatory and antioxidant properties. The varied biological properties of curcumin and lack of toxicity even when administered at higher doses makes it attractive to explore its use in various disorders like diseases of skin. It is good potential agent for wound healing. Materials and methods: Sixty four new Zealand rabbits were used in this study ,they were divided into four groups,each group was subdivided as follows:Experimental groups(8 rabbits) right facial side of animals for essential oil applicati

The optical and structural properties of the nanoparticles is determined using UV-visible, x-ray diffraction (XRD) and field emission scanning electron microscope (FESEM). In addition, the synthesis factors such as the temperature, the molar ratio of silver nitride and thymus vulgaris leaves extract have been investigated. The XRD pattern presented higher intensity for the five characteristic peaks of silver. FESEM images for same samples indicated that the particle size was distributed between 24-56 nm. In addition, it’s observed the formation of some aggregated Ag particles

Achieving and maintaining implant stability are prerequisites for a dental implant to be successful. Resonance Frequency Analysis (RFA) is a noninvasive diagnostic method that measures implant stability. The aim of this study was to investigate the influence of treatment protocol and implant dimensions on primary implant stability utilizing RFA. Materials and methods: This study included 63 Iraqi patients (37 male, 26 female; ranging 22-66 years). According to treatment protocol, the sample was divided into 2 groups; A (delayed) & B (immediate). Dental im
