INTRODUCTION: Infection of Neisseria gonorrhoeae in the pharynx (pharyngeal Ng) is associated with gonococcal transmission and development of antimicrobial resistance. We assessed proportion of and determinants for persistence after treatment of pharyngeal Ng. METHODS: At the STI clinic of Amsterdam, the Netherlands, females-at-risk and men who have sex with men are routinely screened for pharyngeal Ng using an RNA-based nucleic acid amplification test (NAAT; Aptima Combo 2)...

Aspiration pneumonia is a cause of mortality in the elderly. Evaluating swallowing function is important. Videofluoroscopy and flexible endoscopic evaluation of swallowing are comparable; however, observing all swallowing dynamics is impossible using the latter approach. We examined the significance of flexible endoscopic evaluation of swallowing using videofluoroscopy. Thirty-seven patients with dysphagia [70.0 ± 8.9 (range 49-84) years] were included. In random order, patients underwent videofluoroscopy with 10 cc contrast material, once without, and once with an endoscope inserted...

Thymopoiesis strictly depends on the function of the Foxn1 transcription factor that is expressed in the thymic epithelium. During embryonic development, initial expression of the Foxn1 gene is induced in the pharyngeal endoderm by mesenchyme-derived BMP4 signals. Here, by engineering a time-delayed feedback system of BMP inhibition in mouse embryos, we demonstrate that thymopoiesis irreversibly fails if Foxn1 gene expression does not occur during a defining time span in mid-gestation. We also reveal an epistatic interaction between the extent of BMP signalling and the gene dosage of Foxn1...

Negative effort dependence (NED), decreased airflow despite increased driving pressure, has been proposed as a specific obstructive sleep apnea (OSA) phenotypic characteristic. We examined conditions under which NED occurs in a collapsible tube, chamber enclosed, pharyngeal airway bench model, focusing on relationships with surrounding pressure levels and longitudinal strain. Using a vacuum source, graded airflows (V ̇, 0-5 L/s) were generated through a thin walled latex tube enclosed within a rigid, cylindrical chamber, sealed with initial chamber pressures (Pci) of 0-5 cmH2O (separate runs), or open to atmosphere...

Many cases of head and neck cancer are detected on the basis of symptoms and therefore are advanced at the time of diagnosis. Such cancers have been treated by invasive surgery and chemoradiotherapy. Recently, innovative technological developments have been made in gastrointestinal endoscopy in Japan, such as image-enhanced magnifying endoscopy, allowing superficial head and neck cancer to be detected.(1,2) Because superficial head and neck cancer previously could not be detected, diagnostic and treatment strategies have not yet been established and have become a new field of diagnosis and therapy...

The development of the mouth in animals has fascinated researchers for decades, and a recent study proposed the modern view of recurrent evolution of protostomy and deuterostomy. Here we expanded our knowledge about conserved traits of mouth formation in chordates, testing the hypothesis that nitric oxide (NO) is a potential regulator of this process. In the present work we show for the first time that NO is an essential cell signaling molecule for cephalochordate mouth formation, as previously shown for vertebrates, indicating its conserved ancestral role in chordates...

Group A streptococci (GAS) are highly prevalent human pathogens whose primary ecological niche is the superficial epithelial layers of the throat and/or skin. Many GAS strains having a strong tendency to cause pharyngitis are distinct from strains that tend to cause impetigo; thus, genetic differences between them may confer host tissue-specific virulence. In this study, the FbaA surface protein gene is found to be present in most skin specialist strains, but largely absent from a genetically-related subset of pharyngitis isolates...

Regulating gene expression during infection is critical to the ability of pathogens to circumvent the immune response and cause disease. This is true for the group A Streptococcus (GAS), a pathogen that causes both invasive (e.g. necrotizing fasciitis) and non-invasive (e.g. pharyngitis) diseases. The control of virulence (CovR/S) two-component system has a major role in regulating GAS virulence factor expression. The regulator of cov (RocA) protein, which is a predicted kinase, functions in an undetermined manner through CovR/S to alter gene expression and reduce invasive disease virulence...

We have proposed that independent origins of the tympanic membrane (TM), consisting of the external auditory meatus (EAM) and first pharyngeal pouch, are linked with distinctive middle ear structures in terms of dorsal-ventral patterning of the pharyngeal arches during amniote evolution. However, previous studies have suggested that the first pharyngeal arch (PA1) is crucial for TM formation in both the mouse and chick. In this study, we compare TM formation along the anterior-posterior axis in these animals using Hoxa2 expression as a marker of the second pharyngeal arch (PA2)...

BACKGROUND: Dysphagia is a relatively common symptom following laryngectomy. An anterior pharyngeal diverticulum is a rare cause of post-laryngectomy dysphagia. However, it is often an incidental finding on rigid telescopic examination. METHODS AND RESULTS: This article describes two patients with a symptomatic anterior pharyngeal diverticulum. They were treated by transoral micro-endoscopic potassium titanyl phosphate 532 nm laser assisted resection. Both patients could take feeds orally after the procedure without any difficulty...

A flexible laryngeal mask airway device (LMAD) embedded with 2 pharyngeal suction catheters was used for a young female patient who underwent a revision rhinoplasty, septoplasty, and chin implant. The modified LMAD was constructed by attaching 2 suction catheters onto the back of the mask; it functioned well without signs of malfunction or complications, with a total of 71 mL of blood evacuated from the pharyngeal area during the five and a half hour surgery. The patient emerged from anesthesia without coughing or straining, and reported no sore throat or nausea/vomiting in the recovery room...

PURPOSE OF THE STUDY: The aim of the study was to propose "the risk formula" for obstructive sleep apnea in children according to the general and local clinical parameters and findings relevant for obstructive sleep apnea (OSA) severity. The unmet need for this formula arises from the economic burden of polysomnography (device, staff, training, special sleep centers, etc) as the golden standard for the diagnostics. MATERIALS AND METHODS USED: The study was performed from January 2013 until January 2016 in the Sleep Center, Department for Neuroscience, School of Medicine of the University of Split, Department of Pediatrics, University Hospital Split, Croatia and ENT Dept...
