BACKGROUND Flexible bronchoscopy is a procedure commonly performed for diagnostic and therapeutic purposes. The aim of this study was to assess the diagnostic yield and the safety of routine bronchoscopy techniques including transbronchial needle aspiration and transbronchial biopsy at a university hospital in Switzerland. METHODS 616 consecutive bronchoscopies performed at the Pulmonary Medi...

PURPOSE We aimed to investigate the effectiveness and complications of transthoracic CT-guided biopsy techniques. METHODS A total of 94 CT-guided percutaneous transthoracic biopsy procedures performed in 85 patients were retrospectively evaluated. Core biopsy technique was used in 87 procedures and transthoracic fine-needle aspiration biopsy was used in seven procedures. RESULTS Diagnostic ...

BACKGROUND AND PURPOSE Vertebroplasty performed in the mid- and upper thoracic spine presents technical challenges that differ from those in the lower thoracic and lumbar region. We herein report results of percutaneous vertebroplasty for treatment of painful, osteoporotic compression fractures in the mid- and upper thoracic spine. METHODS Retrospective chart review identified vertebroplasty ...

Objective: Major international guidelines have not standardized the sequence of diagnostic examinations during the follow-up of a patient with a diagnosed breast cancer. The aim of this study is to investigate the accuracy of sonography in the diagnosis of loco-regional lymphatic recurrences in comparison to the core needle biopsy results. Materials and Methods: Among 6455 patients who were fol...

AIM To monitor ex vivo intra-canal irrigation with three endodontic needles (25, 27 and 30 gauge) and compare them in terms of irrigant flow rate, intra-barrel pressure, duration of irrigation and volume of irrigant delivered. METHODOLOGY A testing system was constructed to allow measurement of selected variables with pressure and displacement transducers during ex vivo intra-canal irrigation...

Background and aims: Needle stick injuries are a common and serious occupational hazard in the medical settings. So, this study was aimed to assess the incidence of needle stick injury among medical students at Tabriz Imam Reza Hospital in 2014. Methods: This is a cross-sectional study which its data was collected from 211 medical students in Tabriz Imam ...

BACKGROUND Many people who inject drugs (PWID) use syringes with detachable needles, which have high dead space (HDS). Contaminated HDS blood may substantially contribute to the transmission of HIV, hepatitis C (HCV), and other blood-borne viruses within this population. Newly designed low dead space (LDS) syringe-needle combinations seek to reduce blood-borne virus transmission among PWID. We ...

The process of understanding spoken language re quires the e cient processing of ambiguities that arise by the nature of speech This paper presents an ap proach that allows the e cient incremental integra tion of speech recognition and language understand ing using Tomita s generalized LR parsing algorithm For this purpose the GLR lattice parsing algorithm is revised so that an agenda mechanism...
