BACKGROUND Traditionally, acupuncturists manipulate needles to enhance sensations referred to as de qi or 'acupuncture needle sensation'. Acupuncture needle sensations are complex and quantifying the experience has been difficult. The aim of this crossover study was to measure self-reported needle sensation during deep and bi-directional rotated needling in 15 healthy volunteers. METHODS Each...

Abstract Sensor-integrated needles with impedance or other electrochemical sensors have gained increased attention in research. Their potential use is widespread and covers applications such as early disease diagnostics needle guidance for needle-based interventions. However, fabrication sensor integration are crucial parts of realizing functionalized needles. In this paper, a review existing r...

BACKGROUND Short-axis ultrasound-guided placement of central venous catheters (CVCs) is widely accepted as safe practice. However, utilizing the long-axis approach could further improve safety, as it allows for better visualization of the needle as it is advanced to the target vessel. However, the long-axis approach has not widely been used due to the technical difficulty. Recently, a new needl...

Intravenous (IV) access is a common medical procedure in pediatrics. During pediatric IV insertion, a small size needle (22-24 gauge, 0.71-0.56 mm OD) with lancet tip is usually used to pierce into the vessel of the pediatric patient [1-3]. Because the veins of children are very thin, IV insertion is usually difficult. If the patient is very young or with other medical complex conditions, for e...

Background and Objective: Needle stick injuries (NSIs) are a common potential risk for healthcare workers. The aim of this study was to evaluate preventive interventions against needle stick injury incidents among HCWs.   Methods: Seven hospitals in the Iranian Chaharmahal-VA-Bakhtiari Province were surveyed between March 2008 to March 2013. Data of the needle stick injuries of healthcare wor...

Background: Presence of discordance between the Gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. In this study, we determined the accuracy of Gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma i...
