purpose: to determine bacterial contamination of corneas and corneal storage media provided from the eye bank of i.r. iran to rasool akram medical center. methods: this descriptive study was performed on 70 corneoscleral rims and corneal storage media. one milliliter of corneal storage media and the corneoscleral rim were sent to microbiology laboratory at the time of penetrating keratoplasty a...

background and objectives: tetanus and diphtheria are vaccine-preventable, infectious diseases with significant morbidity and mortality. immunization by the diphtheria and tetanus toxoid (dt) has been applied in iran for almost 50 years. however, there are very few data about the rate of immunity to these diseases in the adult population. the humoral immunity to tetanus and diphtheria among blo...

At the present time, increasing the use of living donors offers the best solution to the organ shortage problem. The clinical questions raised when the first living donor kidney transplant was performed, involving donor risk, informed consent, donor protection, and organ quality, have been largely answered. We strongly encourage a wider utilization of living donation and recommend that living d...

PURPOSE To validate tissue quality parameters for donor corneas designated for emergency grafting for corneal graft survival. METHODS In a longitudinal cohort follow-up study, 131 emergency penetrating grafts were studied. Grafts were performed with a pool of organ-cultured donor corneas designated for emergency grafting and prepared for immediate use with all safety tests performed. Assignat...

Organ transplants can improve the life expectancy and quality of life for the recipient but carries the risk of serious post-operative complications, such as septic shock and organ rejection. The probability of a successful transplant depends in a very subtle fashion on compatibility between the donor and the recipient – but current medical practice is short of domain knowledge regarding the co...

A. Survey of Transplantation Techniques The kidney is one of the few organs which can successfully be transplanted from a living donor with current techniques. Since a healthy donor can function satisfactorily with a single kidney, the removal of one of them for transplantation does not significantly endanger live.1,2,3 Removal, or substantial partial removal, of other organs, such a the heart,...

closure of donor site of the flap has special problems. reduction of this site will decrease the morbidity of operation. in this study, we present our experience in donor site size reduction. methods between 2006 and 2008, 15 patients with skin and soft tissue defects underwent operation. in all patients, coverage of defect was performed with various flaps. substratum horizontal mat-tress sutur...

background: hepatitis b is the most common cause of acute viral hepatitis in the world. a small number of epidemiological studies, show the role of sucking insects in the transmission of hepatitis b as mechanical vector .in order to determine the prevalence of hbsag in patients with malaria and to compare with healthy blood donors, this study was conducted. methods: in this case-control study, ...

abstract mutations have been described in all of the four open reading frames of the hepatitis b virus (hbv), however, from a clinical perspective the surface escape mutant is the most troublesome. hepatitis b surface antigen (hbsag) variants may impair diagnosis, or allow the virus to escape vaccine-induced immunity or passive immunoglobulin therapy. hbv mutants with amino acid substitutions, ...

Background: The living donor liver transplantation (LDLT) surgery exposes the healthy donors to the risks associated with a major surgical procedure. The impact that this surgery has on the health-related quality of life (HRQOL) of a donor is an important aspect of outcome. Emerging LDLT centers need to be cognizant of the impact of this major procedure on the donor’s quality of life (QOL). The...
