Narrative review of relationship between chronic cough and laryngopharyngeal reflux.

Gastroesophageal reflux disease (GERD) as a possible cause of chronic cough is known for decades. However, more than 75% of patients with extraoesophageal symptoms do not suffer from typical symptoms of GERD like pyrosis and regurgitations and have negative upper gastrointestinal endoscopy. For such a condition term laryngopharyngeal reflux (LPR) was introduced and is used for more than two decades.

Multiple Infections with Viruses of the Family in Czech Grapevines.

This study focused on the viruses of the family that infect grapevines in the Czech Republic. Complete sequences of GFkV (grapevine fleck virus) and GRGV (grapevine red globe virus) from the genus and GRVFV (grapevine rupestris vein feathering virus) and GSyV-1 (grapevine Syrah virus 1) from the genus were obtained using high-throughput sequencing of small RNAs and total RNAs. Mixed infections with these viruses were observed, as well as several variants of these viruses in the same plant.

Clinical significance of type IV vascularization of laryngeal lesions according to the Ni classification.

Background: Scattered, small, dot-like intraepithelial papillary capillary loops (IPCLs) represent type IV epithelial vascularization according to "Ni classification" and are considered to be nonmalignant. According to the European Laryngological Society classification, these loops are malignant vascular changes. This contradiction has high clinical importance; therefore, clarification of the clinical significance of type IV vascularization according to the Ni classification is needed.

Transnasal Endoscopic Pituitary Surgery-The Role of a CT Scan in Individual Tailoring of Posterior Septum Size Resection.

Objective: This study was designed to evaluate the possibility of predicting the minimum size of septal resection for safe tumor extraction in transnasal paraseptal pituitary adenoma resection from preoperative computed tomography scans.

Methods: A retrospective CT scan analysis was performed on 20 patients who underwent endoscopic pituitary surgery at the University Hospital in Ostrava. Virtual insertion of the straight instrument into the sphenoid cavity was simulated using a CT scan.

Characterization of and A Infecting Myrobalan Rootstock.

(PNRSV) and A (CVA) are two viruses that mainly infect plants of the genus . Full-length sequences of these two viruses, collected in the Czech Republic from plants, were obtained via HTS sequencing. Phylogenetic analyses based on the NJ method and Splitstree tools showed that the Czech PNRSV isolate (ON088600-ON088602) is a divergent isolate from other molecular groups, sharing less than 97% pairwise nucleotide identity with members of other groups.

Detection of single nucleotide polymorphisms in virus genomes assembled from high-throughput sequencing data: large-scale performance testing of sequence analysis strategies.

Recent developments in high-throughput sequencing (HTS) technologies and bioinformatics have drastically changed research in virology, especially for virus discovery. Indeed, proper monitoring of the viral population requires information on the different isolates circulating in the studied area. For this purpose, HTS has greatly facilitated the sequencing of new genomes of detected viruses and their comparison.

Narrative Review of Classification Systems Describing Laryngeal Vascularity Using Advanced Endoscopic Imaging.

Endoscopic methods are critical in the early diagnosis of mucosal lesions of the head and neck. In recent years, new examination methods and classification systems have been developed and introduced into clinical practice. All of these new techniques target the notion of optical biopsy, which tries to assess the nature of the lesion before histology examination.

Computational Fluid Dynamics Could Enable Individualized Surgical Treatment of Nasal Obstruction (A Preliminary Study).

Passage of nasal airflow during breathing is crucial in achieving accurate diagnosis and optimal therapy for patients with nasal disorders. Computational fluid dynamics (CFD) is the dominant method for simulating and studying airflow. The present study aimed to create a CFD nasal airflow model to determine the major routes of airflow through the nasal cavity and thus help with individualization of surgical treatment of nasal disorders.

Evolution of mucosal vasculature after radiotherapy of T1 vocal cord cancer: a pilot study.

Purpose: Narrow-band imaging is the state of the art in the diagnosis of mucosal lesions of the vocal cords. It is also used in the follow-up of patients after surgical therapy. Unfortunately, if a patient has received radiotherapy the follow-up is much more difficult.

Epiglottopexy Is a Treatment of Choice for Obstructive Sleep Apnea Caused by a Collapsing Epiglottis.

Drug-induced sleep endoscopy (DISE) reveals epiglottic collapse to be a frequent cause of obstructive sleep apnea (OSA) and intolerance of positive airway pressure (PAP). These patients require different management. This prospective study aimed to compare transoral laser epiglottopexy outcomes in patients with OSA caused by epiglottic collapse with the patients’ previous PAP outcomes.

Does Bicanalicular Intubation Improve the Outcome of Endoscopic Dacryocystorhinostomy?

Unlabelled: The aim of this study was to compare the success of endoscopic dacryocystorinostomy with and without bicanalicular intubation in the treatment of distal nasolacrimal duct obstruction.

Methods: In a prospective, randomized, comparative study, endoscopic dacryocystorinostomy without bicanalicular silicone intubation (Group I) and endoscopic dacryocystorinostomy with intubation (Group II) were performed in patients with distal nasolacrimal duct obstructions. The tubes were removed 3 months after surgery in Group II, and the patients were followed up for 6 months after surgery.

Internal Carotid Injury during Skull Base Surgery-Case Report and a Review of the Literature.

Iatrogenic injury of the internal carotid artery (ICA) is a rare, and probably underreported, complication of transnasal endoscopic skull base surgery. Although treatment algorithms have been suggested, there is no definite consensus or guideline for the management of this severe complication. We describe a case of ICA injury that occurred during a transsphenoidal biopsy of a tumor in the cavernous sinus and we present a treatment algorithm for managing this complication.

Association Between Inferior Turbinate Hypertrophy and Extraesophageal Reflux.

Importance: To the authors' knowledge, no prior studies have examined the association between inferior turbinate hypertrophy (ITH) and extraesophageal reflux (EER). If EER were a cause or cofactor of ITH, antireflux treatment can be considered prior to surgical intervention.

Objective: To evaluate EER presence and severity in patients with different degrees of ITH.

Solid Anorganic Particles and Chronic Rhinosinusitis: A Histopathology Study.

Although extensive research has shown the pathological effect of fine and ultrafine airborne particles, clear evidence of association of environmental exposure to them and inflammatory changes in human nasal mucosa is missing. Meanwhile, pathogenesis of chronic rhinosinusitis, despite being a disease with high prevalence in the population, is still unclear. The increasing evidence of the pro-inflammatory properties of these particles raises the question of their possible role in chronic rhinosinusitis.

Tonsillar origin of deep neck infection as a negative prognostic factor for developing complications.

<b>Aim:</b> The aim of this study was to compare the odontogenic and tonsillar origins of deep neck infection (DNI) as a negative prognostic factor for developing complications. </br></br> <b>Methods:</b> This was a retrospective study of 544 patients with tonsillar and odontogenic origins of DNI treated between 2006 and 2015 at 6 ENT Departments and Departments of Oral and Maxillofacial Surgery. Complications from DNI (descending mediastinitis, sepsis, thrombosis of the internal jugular vein, pneumonia, and pleuritis) were evaluated in both groups and compared.

Identification of the phase composition of solid microparticles in the nasal mucosa of patients with chronic hypertrophic rhinitis using Raman microspectroscopy.

Solid particles, predominantly in micron and submicron sizes, have repeatedly been observed as a threat to a human health unique compared to the other textures of the same materials. In this work, the hypothesis the solid metal-based particles play a role in the pathogenesis of chronic hypertrophic rhinitis was investigated in patients who had not responded positively to medication. In the group of 40 randomly selected patients indicated for surgical mucotomy, the presence of solid micro- and submicron particles present in their nasal mucosa was assessed.

Diagnosis of Laryngeal Pemphigus Vulgaris Can Be Facilitated Using Advanced Endoscopic Methods.

Isolated laryngeal pemphigus vulgaris (LPV) is rare; however, early diagnosis is crucial in determining its course and prognosis. This paper aims to describe mucosal vascular changes typical for LPV using advanced endoscopic methods, which include Narrow Band Imaging (NBI), IMAGE1-S video-endoscopy and enhanced contact endoscopy (ECE). Retrospective analysis of all laryngeal mucosal lesion examined using advanced endoscopic methods during 2018-2020 at tertiary hospital was performed.

Diagnostic Value of the Peptest in Detecting Laryngopharyngeal Reflux.

Background: The Peptest is a non-invasive diagnostic test for measuring the pepsin concentration in saliva, which is thought to correlate with laryngopharyngeal reflux (LPR). The aim of this study was to investigate the diagnostic value of the Peptest in detecting LPR based on 24-h multichannel intraluminal impedance-pH (MII-pH) monitoring using several hypopharyngeal reflux episodes as criterion for LPR.

Methods: Patients with suspected LPR were examined with the Reflux Symptom Index (RSI), Reflux Finding Score (RFS), fasting Peptest, and MII-pH monitoring.

Chondrosarcoma of the Thyroid Cartilage Successfully Treated With Partial Resection of the Thyroid Cartilage.

Chondrosarcoma of the thyroid cartilage is a sporadic disease with nonspecific clinical presentation. Smooth swelling of the supraglottic area should arouse suspicion of possible pathology. In addition to laryngoceles, which usually do not have a significant impact, otolaryngologists should consider chondrosarcoma of the thyroid cartilage and indicate computed tomography (CT).

Individualised Timing of Radio-Guided Parathyroidectomy Using Multi-Phase SPECT/CT Increases In Vivo Sensitivity and Accuracy and Reduces Operating Time: A Randomised Clinical Trial.

: Minimally invasive parathyroidectomy is the preferred treatment for primary hyperparathyroidism. Despite relatively accurate preoperative information, minimally invasive parathyroidectomy can be challenging, especially in the case of small and ectopic adenomas. Radio guidance aids in both in vivo identification and ex vivo confirmation of adenoma.

BLOW-IN FRACTURE OF ORBITAL ROOF. CASE REPORT.

Orbital fractures may be accompanied with severe damage of the eye bulb and other intraorbital tissues. Early clinical findings can be very mild, therefore it is vital to actively seek not only for any damage done to the soft tissues of the orbit, but also for extraorbital complications such as liquorrhea or meningitis. We report a relatively rare case of blow-in fracture of orbital roof in eleven years old boy.
