background: needlestick injuries (nsis) are among the most important occupational injuries for health care workers (hcws). in iran, the problem of exposure to contaminated blood among nursing personnels has not well documented. the aim of this study was to determine the incidence of needlestick injuries in population of nurses in shahroud imam hossein hospital, northern iran. methods: a self-ad...

introduction: the preoperative diagnostic evaluation of the parotid lesion is a valuable aid in planning the operation and the approach to intervention. among different diagnostic tools, fine needle aspiration has a key role. however, the exact efficacy of this technique in our center had not been thoroughly investigated. materials and methods: between january 2000 and june 2007 a subset of 64 ...

Reliable induction of foaming is indispensable for vacuum foam drying. We previously showed that, adequate partial drying followed by puncturing a solution with needle (needle stimulation) resulted in the foaming, even under insufficient where minimal. Herein, characteristics needle-stimulation-induced was investigated, focusing on impact viscosity and vapor pressure. Different combinations sol...

PURPOSE To quantify needle placement accuracy of magnetic resonance image (MRI)-guided core needle biopsy of the prostate. MATERIALS AND METHODS A total of 10 biopsies were performed with 18-gauge (G) core biopsy needle via a percutaneous transperineal approach. Needle placement error was assessed by comparing the coordinates of preplanned targets with the needle tip measured from the intrapr...

objectives this study aimed to examine the relationship between patients’ anthropometric characteristics and depth of spinal needle insertion to the subarachnoid cavity. patients and methods 385 patients with asa class i – ii, aged 18 - 65 years and undergoing elective surgery of the lower abdomen and extremities under spinal anesthesia, were selected for this cross-sectional study. the patient...

conclusions although the presence of pni in prostate biopsy is accompanied by higher surgical stages, pni is not an appropriate independent factor in risk stratification. patients and methods this cross-sectional study was conducted using a sample of 109 patients who attended a tertiary health care center from 2008 to 2013. the selection criteria were pni in prostate biopsy with gleason scores ...

A needle-tissue interaction model is an essential part of every needle insertion simulator. In this paper, a new experimental method for the modeling of needle-tissue interaction is presented. The method consists of measuring needle and tissue displacements with ultrasound, measuring needle base forces, and using a deformation simulation model to identify the parameters of a needle-tissue inter...

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...
