OBJECTIVE: To present a minimization-cost analysis to compare reusable and single-use fiberscopes in a French health institution. MATERIALS AND METHODS: The amortization cost assessment has been achieved over a period of five years, and took into account the acquisition and maintenance costs, as well as the costs related to disinfection of reusable fiberscopes. The cost of single-use fiberscopes was calculated according to its acquisition and elimination costs. Finally, we compared the costs of single-use vs...

BACKGROUND: Conventional intubation of the trachea and consequent prone positioning of anesthetized patients with cervical spine instability may result in secondary neurological injury. Historically, flexible fiberoptics used to be the chief choice for patients presenting with cervical spine instability surgery with difficult airway. Recently, the rigid optical stylets have shown promise in assisting difficult intubations. PURPOSE: The aim of the present study was to compare the efficacy of Shikani optical stylet (SOS) with the flexible fiberscope for awake intubation in patients with cervical spine instability...

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) is a common surgical procedure and established as first choice for securing the airway in critically ill patients needing prolonged mechanical ventilation. There are case reports of open tracheostomy through paramedian approach without complications. This case report presents a case of PDT through paramedian approach. CASE REPORT: An 18 year old female, case of firearm injury underwent cervical esophagostomy on the left side of neck approaching midline...

PURPOSE: To demonstrate a proof of concept of magnetic resonance (MR) coagulation, in which MR imaging scanner-induced radiofrequency (RF) heating at the end of an intracatheter long wire heats and coagulates a protein solution to effect a vascular repair by embolization. MATERIALS AND METHODS: MR coagulation was simulated by finite-element modeling of electromagnetic fields and specific absorption rate (SAR) in a phantom. A glass phantom consisting of a spherical cavity joined to the side of a tube was incorporated into a flow system to simulate an aneurysm and flowing blood with velocities of 0-1...

In this study, an innovative approach based on fiberoptically coupled substrate-integrated hollow waveguide (iHWG) gas cells for the analysis of low sample volumes suitable for remote broad- and narrow-band mid-infrared (MIR; 2.5-20 μm) sensing applications is reported. The feasibility of remotely addressing iHWG gas cells, configured in a double-pass geometry via a reflector, by direct coupling to a 7-around-1 mid-infrared fiber bundle is demonstrated, facilitating low-level hydrocarbon gas analysis. For comparison studies, two iHWGs with substrate dimensions of 50×50×12 mm (L × W × H) and geometric channel lengths of 138 mm and 58...

REVIEW
C Schwemmle, C Arens
Swallowing is a dynamic process that requires more than 30 muscles in the recruitment/coordination of the lips, tongue, palate, pharynx, larynx and esophagus. The eating and swallowing procedure is learned in sensitive or critical periods: when a certain degree of maturation has been achieved, the appropriate stimulus permits a certain milestone of development to occur. The swallowing procedure occurs in three main stages oral, pharyngeal, and esophageal. Therefore, swallowing disorders may present in any, some, or all of these stages in addition to feeding problems...

Recent studies have shown an association between alterations in laryngopharyngeal mechanosensitivity (LPMS) and dysphagia, obstructive sleep apnea, and chronic cough hypersensitivity syndrome. A previous reliability study of a new laryngopharyngeal endoscopic esthesiometer and rangefinder (LPEER) showed high intra- and inter-rater reliability; however, its accuracy has not been tested. We performed an accuracy study of the LPEER in a prospectively and consecutively recruited cohort of 118 patients at two tertiary care university hospitals...

BACKGROUND: Around 10%-20% of burned patients have inhalation injuries, and the severity of these injuries is correlated with mortality. Fiberoptic bronchoscopy is an important tool for the early diagnosis of inhalation injury. This study investigated correlations between the severity of inhalation injury and outcomes of patients involved in a cornstarch dust explosion in northern Taiwan in 2015. METHODS: Patients with burns who were intubated after the explosion were enrolled...

BACKGROUND: The Eustachian tube (ET) has a major role in the middle ear (ME) pressure homeostasis. ET dysfunction is the accepted paradigm for pressure-related ME disorders. We studied the ME status in patients with severely diminished ET opening abilities, and anticipated to find ME disorders in most of them. PATIENTS AND METHODS: ME status was evaluated in unconscious adults, who were hospitalized in a rehabilitation center with severe brain damage, requiring tracheotomy and gastrostomy...

AIM: To study the value of ultrasound-guided core needle biopsy (CNB) in the diagnosis of T3 or T4 stage laryngeal and hypopharyngeal cancer, which is difficult by routine methods. PATIENTS AND METHODS: Nineteen cases of T3 or T4 stage laryngeal or hypopharyngeal carcinoma with abnormal pharyngeal sensitivity, severe dyspnea, submucous cancer recurrence, cardiovascular and pulmonary dysfunction were reviewed retrospectively from October 2012 to October 2014 in the Yuhuangding Hospital of Qingdao University...

PURPOSE: The aim of this study was to investigate the diagnostic efficacy and image quality of magnetic resonance enterography (MRE) using oral mannitol solution for the evaluation Crohn disease (CD). MATERIALS AND METHODS: We retrospectively evaluated MRE examinations of 153 patients with an assumed or definitive diagnosis of CD. There were 65 men and 88 women, with a mean age of 35.7 years (range: 6-73years). MRE findings of the patients were compared to histopathologic results obtained by surgery-fiberoptic endoscopy...

Importance: Annually in the United States, at least 3.5 million people seek medical attention for traumatic brain injury (TBI). The development of therapies for TBI is limited by the absence of diagnostic and prognostic biomarkers. Microtubule-associated protein tau is an axonal phosphoprotein. To date, the presence of the hypophosphorylated tau protein (P-tau) in plasma from patients with acute TBI and chronic TBI has not been investigated. Objective: To examine the associations between plasma P-tau and total-tau (T-tau) levels and injury presence, severity, type of pathoanatomic lesion (neuroimaging), and patient outcomes in acute and chronic TBI...

Reliable acoustic characterization is fundamental for patient safety and clinical efficacy during high-intensity therapeutic ultrasound (HITU) treatment. Technical challenges, such as measurement variation and signal analysis, still exist for HITU exposimetry using ultrasound hydrophones. In this work, four hydrophones were compared for pressure measurement: a robust needle hydrophone, a small polyvinylidene fluoride capsule hydrophone and two fiberoptic hydrophones. The focal waveform and beam distribution of a single-element HITU transducer (1...

Purpose: Clinicians often test laryngeal sensation by touching the laryngeal mucosa with the tip of a flexible laryngoscope. However, the pressure applied to the larynx by using this touch method is unknown, and the expected responses elicited by this method are uncertain. The variability in pressure delivered by clinicians using the touch method was investigated, and the subject responses to the touches were also reported. Methods: A fiberoptic pressure sensor passed through the working channel of a laryngoscope, with its tip positioned at the distal port of the channel...

INTRODUCTION: Currently, neoplasms of the trachea and lower airway demand open transcervical approach with or without thoracotomy. We describe here a novel, minimally invasive approach for an intraluminal lesion of the thoracic trachea, called percutaneous trans-tracheal endoscopic approach (PTEA). Apart from obvious advantages over potentially morbid open procedures, this technique has certain peculiar benefits over rigid or flexible bronchoscopic approach. MATERIALS AND METHODS: A 43-year-old male patient had glomus tumor of thoracic trachea...

Adults with COPD frequently present with dysphagia, which often leads to clinical complications and hospital admissions. This study investigates the ability of the Eating Assessment Tool (EAT-10) to predict aspiration during objective dysphagia evaluation in adults with stable COPD. Thirty adults (20 male, 10 female; mean age = 69.07 ± 16.82) with stable COPD attended an outpatient dysphagia clinic for a fiberoptic endoscopic evaluation of swallowing (FEES) in an acute teaching hospital (January 2015-November 2016)...
