A highly protective malaria vaccine would greatly facilitate the prevention and elimination of malaria and containment of drug-resistant parasites. A high level (more than 90%) of protection against malaria in humans has previously been achieved only by immunization with radiation-attenuated Plasmodium falciparum (Pf) sporozoites (PfSPZ) inoculated by mosquitoes; by intravenous injection of aseptic, purified, radiation-attenuated, cryopreserved PfSPZ ('PfSPZ Vaccine'); or by infectious PfSPZ inoculated by mosquitoes to volunteers taking chloroquine or mefloquine (chemoprophylaxis with sporozoites)...

Aseptic techniques are those practices designed to reduce the risk of surgical site infection (SSI), defined as such, all those that occur within the first 30 days of the procedure. While the patient’s risk of developing an SSI in dermatologic surgery is low since many of the procedures are considered sterile, there are different factors associated with an increased or decreased risk of developing SSI. The characteristics of the surgical wound (such as involving infected or inflamed tissue or when breaks in the aseptic technique occur), patient characteristics (such as age, comorbidities, medication use and smoking) and procedure factors (such as setting, surgical technique, type of procedure, duration and body region involved)...

BACKGROUND: There is little evidence to inform practice regarding the optimum aseptic technique of drawing up saline for epidural insertion. Our regional practice is to draw up saline from a non-sterile packaged plastic ampoule, therefore introducing the risk of bacterial contamination. Usually, the anaesthetist draws up saline directly from the vial held by an assistant using a needle (needle technique). Alternatively, the saline vial is emptied onto a sterile tray by an assistant and then drawn up by the anaesthetist (tray technique)...

BACKGROUND: In past decades, polyethylene wear was a major cause of failure in total knee arthroplasty (TKA). Polyethylene for use in arthroplasty has been vastly improved in recent years, with improved materials as well as manufacturing and sterilization processes. Testing has shown that infusion of vitamin E prevents oxidative degradation of polyethylene without remelting, allowing the material to maintain mechanical properties and wear resistance over time. The purpose of this study is to review the early result of patients undergoing primary TKA with vitamin E antioxidant-infused polyethylene inserts...

BACKGROUND: The use of acellular dermal matrices (ADMs) has become the standard of practice in many reconstructive and aesthetic surgical applications. Different methods used to prepare the allograft tissue for surgical use can alter the ADMs natural properties. Aseptic processing has been shown to retain the natural properties of ADMs more favorably than terminally sterilized ADMs. Terminal sterilization has been historically linked to alteration of biological materials. In vitro work was conducted to compare ADM processing methods...

INTRODUCTION: In fetuses who are predicted to be at risk of catastrophic airway obstruction at delivery, the ex utero intrapartum treatment (EXIT) procedure is useful for securing the fetal airway while maintaining fetal oxygenation via placental circulation. Factors, including poor posture of the fetus and physician, narrow visual field, and issues of contamination in the aseptic surgical field, make fetal intubation during the EXIT procedure difficult. Herein, we report our experience of the usefulness of the GlideScope video laryngoscope (GVL) for intubation during the EXIT procedure...

INTRODUCTION: Conventionally postpartum hemorrhage (PPH) has been defined as blood loss of more than 500 ml following vaginal delivery and 1000 ml following a cesarean section [Pritchard et al. in Am J Obstet Gynecol 84(10):1271-1282, (1962)]. Another definition labels PPH as any blood loss which causes a 10 % drop in hematocrit [Combs et al. in Obstet Gynecol 77:69-76, (1991)] or which threatens the hemodynamic stability of the patient and necessitates blood transfusion [Prendiville et al...
