Multidisciplinary system for detecting medication errors in antineoplastic chemotherapy.

2009

Objective. To analyze medication errors (MEs) in a multidisciplinary system with a Computerized Pharmacotherapy Process (CPP) in cancer patients. Design. A longitudinal, prospective 2-year (January 2003 —to December 2004) cohort study was made in adult patients administered antineoplastic treatment in Services of Oncology and Haematology. MEs were identified by double cross-validation of each stage of the pharmacotherapeutic process (prescription, preparation, dispensing, administration, and follow-up) carried out by the multidisciplinary team (physician, pharmacist, nurse) with CPP assistance. Variables. Number of MEs per 1000 patient-days, percentage according to the stage of the pharmac…

Importance of calibration for diameter and area determination by intravascular ultrasound

1996

Intravascular ultrasound (IVUS) permits quantitative assessment of the lumen diameter and area of coronary arteries. The experimental study was performed to evaluate the accuracy of diameter and area measurements.Lumen quantitation (lumen diameter D and cross-sectional area A) in lucite tubes (lumen diameter 2.5 to 5.7 mm, Plexiglas) was performed using a mechanical IVUS system (HP console, 3.5 F catheter, Boston Scientific, 30 MHz). The influence of fluid type (blood, water and saline solution), fluid temperature (20 degrees C/37 degrees C), catheter to catheter variation, gain setting and ultrasound frequency (12, 20 and 30 MHz) was determined. In blood at 20 degrees C there was a constan…

Fire in operating room: The adverse "never" event. Case report, mini-review and medico-legal considerations.

2020

Abstract The patient’s security and safety represent a topic of great importance for public health that led several healthcare organizations in many Countries to share documents to promote risk management and preventing adverse events. Surgical Fire (SF) is an infrequent adverse event generally occurring in the operating room (OR) and consisting of a fire that occurs in, on, or around a patient undergoing a medical or surgical procedure. Here a medico-legal case involving a 65-year-old woman reporting burns to the neck due to an SF during a thyroidectomy was described. A literature review was performed using Pubmed and Scopus databases, focusing on epidemiology, causes, prevention activitie…

Common and uncommon pitfalls in pancreatic imaging: it is not always cancer.

2015

Despite advances in multimodality imaging of pancreas, there is still overlap between imaging findings of several pancreatic/peripancreatic disease processes. Pancreatic and peripancreatic non-neoplastic entities may mimic primary pancreatic neoplasms on ultrasound, CT, and MRI. On the other hand, primary pancreatic cancer may be overlooked on imaging because of technical and inherent factors. The purpose of this pictorial review is to describe and illustrate pancreatic imaging pitfalls and highlight the basic radiological features for proper differential diagnosis.

Newborn screening of inherited metabolic disorders by tandem mass spectrometry: past, present and future

2013

Inborn errors of metabolism are inherited biochemical disorders caused by lack of a functional enzyme, transmembrane transporter, or similar protein, which then results in blockage of the corresponding metabolic pathway. Taken individually, inborn errors of metabolism are rare. However, as a group these diseases are relatively frequent and they may account for most of neonatal mortality and need of health resources. The detection of genetic metabolic disorders should occur in a pre-symptomatic phase. Recently, the introduction of the tandem mass spectrometric methods for metabolite analysis has changed our ability to detect intermediates of metabolism in smaller samples and provides the mea…

A Review of Healthcare Failure Mode and Effects Analysis (HFMEA) in Radiotherapy

2016

This paper presents a review of risk analyses in radiotherapy (RT) processes carried out by using Healthcare Failure Mode Effect Analysis (HFMEA) methodology, a qualitative method that proactively identifies risks to patients and corrects medical errors before they occur. This literature review was performed to provide an overview of how to approach the development of HFMEA applications in modern RT procedures, comparing recently published research conducted to support proactive programs to identify risks. On the basis of the reviewed literature, the paper suggests HFMEA shortcomings that need to be addressed.

Pitfalls in whole body MRI with diffusion weighted imaging performed on patients with lymphoma: What radiologists should know

2016

The technological advances in radiological imaging and the relevance of a diagnostic tool that may reduce radiation-induced long-term effects have led to a widespread use of whole body magnetic resonance imaging (WB-MRI) with diffusion weighted imaging for oncologic patients. A lot of studies demonstrated the feasibility and reliability of WB-MRI as an alternative technique for lymphoma staging and response assessment during and after treatment. In this paper, taking advantage of our 2years of experience using WB-MRI for lymphoma, we discuss the main pitfalls and artifacts radiologists should know examining a WB-MRI performed on this typology of patients in order to avoid images misinterpre…

<p>Visual And Refractive Outcomes In Hyperopic Pseudophakic Patients Implanted With A Trifocal Intraocular Lens</p>

2019

Purpose To assess visual and refractive results after bilateral implantation of a trifocal intraocular lens (IOL) in patients with hyperopia. Methods In a retrospective nonrandomized study, 196 eyes of 98 patients had bilateral implantation of a trifocal IOL. The Barrett Universal II formula was used for IOL power calculation. Eyes were divided into two groups for their analysis: low-moderate, with IOL power ranging from 22 to 26 D, and high, with IOL power ranging from 25 to 34 D. Refractive error was used to assess predictability, and corrected distance visual acuity (CDVA) and uncorrected distance visual acuity values were used to assess efficacy and safety of the surgery. Results Six mo…

Ergebnisse nach Implantation einer Worst Iris Claw Lens zur Korrektur der hohen Myopie

2001

Fragestellung. Ziel dieser prospektiven klinischen Studie war die Erfassung der Refraktion, des korrigierten Visus und des Vorderkammerreizzustandes nach Implantation einer Worst Iris Claw Lens zur Korrektur der hohen Myopie. Patienten und Methode. Von Dezember 1996 bis Februar 1999 wurde bei insgesamt 44 phaken Augen von 28 Patienten eine Worst Iris Claw Lens implantiert. Es folgte eine Nachbeobachtungszeit von 6 Wochen bzw. 6 Monaten. Ergebnisse. Das mittlere praoperative spharische Aquivalent betrug −17,35±3,57 dpt. Sechs Monate postoperativ lag die Refraktion bei 79% der Augen im Intervall von ±1,0 dpt von der Zielrefraktion entfernt. Der mittlere korrigierte Visus stieg von praoperativ…
