[Seroprevalence of HIV infection among high-risk groups in Kohgiloyeh and Boyerahmad province in 2009]

According to WHO report, there are more than 40.3 million people infected with HIV worldwide. Detection of HIV-infected people in each community helps to control and prevent the infection. This study aimed to evaluate the prevalence of HIV infection among high-risk groups in Kohgiloyeh and Boyerahmad province in Iran. This was a cross-sectional study which was conducted in 2009 in Kohgiloyeh and Boyerahmad province in Iran. High-risk groups for HIV were the subjects of this study. Blood samples were taken from 2009 from 2009 people from Boyerahmad Gachsaran, and Dehdasht and tested by ELISA for anti-HIV 1/2 antibodies. Demographic features of participants were recorded using a questionnaire during sample collecting. Collected data were analyzed by SPSS version 13 software. From 2009 subjects, HIV antibody was detected in 36 [1.8%] of cases. High prevalence of infection [3.2%] was seen in 31-40 years age group. The rate of infection was higher in males compared to females. Unemployed people were found to be the main victim of the disease. The highest rate of infection was seen in Gachsaran in comparison to other townships. Findings of the study demonstrated that HIV infection is prevalent in high-risk groups in Kohgiloyeh and Boyerahmad province and control measurements should be implemented to prevent the distribution of the infection

[Seroepidemiological study of brucellosis in high risk groups in Boyerahmad 1384]

Brucellosis is a zoonotic disease that may have a major public health and economic impact in most countries. The disease appears as a Malt fever in humans and abortion in animals. This study was designed to determine the serologic titer of Brucella in high risk and non high risk people in Boyerahmad. A retrospective seroepidemiological study was performed on samples collected from 604 high risk and non high risk people using Rose Bengol test, tube standard test as a rapid test and 2 mercaptoethanol [2ME] and comb's wright as a confirmatory test. The data collected were analyzed by X[2] test via SPSS. Seroprevalence of Brucellosis in high risk people appeared to be high in the Rose Bengal and tube standard test [TST] 6.62 at titer >/= 1/40 whereas for non high risk it was 0%. Confirmation test in high risk people was shown with 2ME in four people. Brucellosis is a major cause of disease in high risk people which can be due to direct or indirect contact with diary products of the related animals

Evaluation of the effects of sodium hypochlorite disinfection on alginate impression by immersion and spraying methods

Difficulties in sterilizing impressions by traditional methods have led to chemical disinfections as an alternative, and some studies have shown that some methods may adversely affect impressions. This study evaluated the effectiveness of 5.25% sodium hypochlorite spray and immersion disinfection methods on irreversible hydrocolloid impressions [Iralgin alginate]. In this study, twenty normal individuals were randomly selected. Impressions were made by a sterile tray from the maxillary arch and then were contaminated with the following organisms: staphylococcus aureus, streptococcus mutans, beta-hemolytic streptococcus type A, Pseudomonas aeruginosa, Escherichia coli and Candida albicans. Impressions were cut and divided into three sections anterioposteriorly and longitudinally. Then, sections were randomly placed in three groups as 1] control [without disinfection], 2] immersion and 3] spray. Then, the provided samples [pieces] of impression materials were cultured and microbial count of the three groups were compared. All of agar models from 20 alginate pieces in control group showed a positive microbial growth. Ten agar models form 20 alginate pieces which were disinfected by spraying method, showed also positive microbial growth and only 2 agar models out of 20 alginate pieces which were disinfected by immersion method showed a positive microbial growth. The mean number of organisms recovered form the surface of the impressions in control group was 3.52><10[8] CFU/ml while in spay and immersion groups it was 132217 CFU/ml and 1915 CFU/ml respectively. According to the results of this study, disinfection by immersion method with 5.25% sodium hypochlorite was more effective than the spray method

[Resulted outcome of artificial bone transplant in treatment of bone diseases]

Introduction: Bone transplant can be used to repair bone defects for bone grafts, alograft, autograft and synthetic bonegraft can be mentioned. Autograft is the idea transplant. But due to complication and limitation in rate of bone and difficulty providing alograft, using synthetic bonegraft in repairing bone defects are becoming popular

Objective: The aim of this survey was to evaluate resulted outcome of artficial bone transplant in treatment of bone diseases

Materials and Methods: 62 patients with bone defects who needed bone graft during one year, under went Nova Bone graft. Follow-up data were analyzed according to graft failure and bone formation

Results: 6 patients out of 62 file to form calcium after 20 weeks of follow-up [9.7%]. There were no other complications [infection and noninfection]

Conclusion: Using SBG [including Nova Bone] has been advocated recently due to several problems including Allografts and Autografts. Favorable results [90.3% calcium formation] in Patients with Nova Bone grafts [alone or in combination with auto and Allograft] propose the regular use of it for patients need bone grafts
