Five techniques for delivering ZOE into straight and curved simulated root canals were investigated for their depthof-fill capabilities. The techniques tested were those using the endodontic pressure syringe, the mechanical syringe, the lentuIo spiral, the JiffyTM Tube, and the tuberculin syringe. Statistical analysis revealed that the instruments of choice for filling straight canals were the ...

BACKGROUND The incidence of HIV among persons who inject drugs (PWIDU) has fallen in many nations, likely due to successes of clean needle/syringe exchange and substance abuse treatment and service programs. However in Pakistan, prevalence rates for PWID have risen dramatically. In several cities, prevalence exceeded 20% by 2009 compared to a 2003 baseline of just 0.5%. However, no cohort study...

Sin Nombre virus (SNV) and Andes virus (ANDV) cause most of the hantavirus pulmonary syndrome (HPS) cases in North and South America, respectively. The chances of a patient surviving HPS are only two in three. Previously, we demonstrated that SNV and ANDV DNA vaccines encoding the virus envelope glycoproteins elicit high-titer neutralizing antibodies in laboratory animals, and (for ANDV) in non...

This study aimed to evaluate the diagnostic utility of Fine Needle Aspiration Cytology (FNAC) in evaluation neoplastic cutaneous nodular skin lesions and provide insights from a tertiary care institute. A total 150 patients with were included study, FNAC was performed using 23-gauge needle attached 10-ml syringe. The found that is valuable tool for lesions. It had sensitivity 88% specificity 10...

Figure 4 4) Constant force on the plunger that automatically depresses when the epidural needle enters the epidural space eliminates the subjective “feel” required with standard LOR syringes. 5) Air Vs Saline: As no subjective feel is required, technically saline is as good as air. Thus by avoiding air complications related to it like, patchy block, risk of venous air embolism can be avoided. 6...

background and objectives: exposure to contaminated needlesticks and sharp devices is an important occupational hazard among healthcare workers. the objective of this study was to gain further insight into prevalence and risk factors of needlestick and sharps injuries among healthcare workers. methods: a cross-sectional survey was carried out among 384 healthcare workers of two hospitals in ne...
