Thin-caliber (4.9 and 6.3 mm) flexible bronchoscopes already provided with a suction button have been modified by adding an air/water button for the control of air insufflation and water irrigation; the channel used is the biopsy-suction one. With the aid of this instrument, several pathologies can be studied and treated, under adverse conditions such as esophageal or recto-sigmoidal stenosis, hematuria in polytraumatic patients, residual stones in patients carrying a T-tube, acute respiratory obstructions, etc.

Equivalent performance of single-use and reusable duodenoscopes in a randomised trial.
Gut
May 2021
Center for Interventional Endoscopy, AdventHealth, Orlando, Florida, USA
Objective: Single-use duodenoscopes have been recently developed to eliminate risk of infection transmission from contaminated reusable duodenoscopes. We compared performances of single-use and reusable duodenoscopes in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP).
Design: Patients with native papilla requiring ERCP were randomised to single-use or reusable duodenoscope.
Attenuation correction effects on SPECT/CT procedures: phantoms studies.
Annu Int Conf IEEE Eng Med Biol Soc
August 2015
Attenuation correction is widely used in SPECT/CT (Single Photon Emission Computed Tomography) procedures, especially for imaging of the thorax region. Different compensation methods have been developed and introduced into clinical practice. Most of them use attenuation maps obtained using transmission scanning systems.

Dipartimento di Medicina Sperimentale ed Applicata, Cattedra di Igiene e Odontoiatria Preventiva, Università degli Studi di Brescia, Brescia, Italy.
Background: Bacterial contamination in dental offices plays a primary role in the evaluation of infective risks for patients and dental personnel. The aim of the research was to study bacterial contamination in eight Italian dental offices by investigating the water of dental units, the air and certain surfaces (push-button panel and instrument cabinet) in order to evaluate potential risks in dental practices.
Methods: The water underwent a microbiological test as specified by Italian law (DPR 236/88).
