Iranian joint registry (iranian national hip and knee arthroplasty registry)

Periodic evaluation and monitoring the health and economic outcome of joint replacement surgery is a common and popular process under the territory of joint registries in many countries. In this article we introduce the methodology used for the foundation of the National Iranian Joint Registry (IJR) with a joint collaboration of the Social Security Organization (SSO) and academic research departments considering the requirements of the Iran's Ministry of Health and Education. ©BY THE ARCHIVES OF BONE AND JOINT SURGERY

Characterization of Specific IgE Antibody Related to Antigen 5 of Echinococcus granulosus

Background: Anaphylactic reactions, such as urticaria, edema, respiratory symptoms, and anaphylactic shock often complicate the course of Cystic Echinococcosis (CE). Methods: To investigate the role of the IgE immunoreactive antigen 5 (Ag 5) in the sero-positive patients with CE, we determined N-terminal of 57 kDa subunit of Ag5 responsible for IgE and C-terminal of this active antigen related to induction of IgG specifically. Results: Immunoblotting analysis showed that specific IgE to 57-kDa subunit related to inter-chain disulphide band of two 22 kDa and 38-kDa component of Ag5 and conformational epitope on this subunits. In addition, since the 57 kDa component arise from the removal of the C-terminal portion of 22 kDa subunit of Ag5, thus IgE specifically recognized N-terminal of 22 kDa subunit which remain bounds to the other component, whereas IgG reacted with C-terminal of 38 kDa component of Ag5. Conclusion: Recognition of the specific binding site on the 57 kDa subunit of Ag5 could leads to understanding the mechanism regulating IgE/IgG production in some immune circumstances that IgE tends to some dominate, whereas in other IgG predominates

Antimicrobial activity of ketoconazole and fluconazole against metronidazole resistance strains of Helicobacter pylori

Resistance to drug such as metronidazole is one the commonest causes of treatment failure while eradicating Helicobacter pylori. Considering the safety of ketoconazole and fluconazole and their inhibitory activity on biosynthesis of fatty acids from cholesterol in cell membrane of H.pylori, the idea of their efficacy against H.pylori is raising. The aim of this study is to evaluate susceptibilities of metronidazole-resistant strains of H.pylori against two antifungal drugs, ketoconazole and fluconazole. In this prospective crosssectional study, 35 isolates of H.pylori from patients with digestive disorders were recruited. Plates were incubated microaerobically. Resistance to metronidazole, minimum inhibitory concentrations (MIC) of ketoconazole and fluconazole for H.pylori isolates were determined by two methods: disc diffusion and agar dilution. Disc diffusion method indicated that metronidazole resistance was seen in 11 strains out of 35. Ketoconazole and fluconazole MICs were 8 and 40mg/lit, respectively, which was confirmed by agar dilution method. Ketoconazole and fluconazole showed an excellent in vitro activity against the H.pylori isolates. However, in vivo activity of these drugs should be evaluated in controlled clinical trials.
