Purpose/Aim: Cystic fibrosis (CF) is the most common, fatal recessive genetic disease among the Caucasian population. Gene therapy has the potential to treat CF long term, however physiological barriers can prevent VSV-G pseudotyped lentiviral (LV) vectors from efficiently accessing the relevant receptors on the basolateral membrane of airway epithelial cells. The aims of this experiment were to use our new dose delivery techniques to determine whether conditioning the mouse lung conducting airways with lysophosphatidylcholine (LPC) improves the level of airway gene expression...

BACKGROUND: While Eustachian tube dysfunction (ETD) is a known comorbidity of chronic rhinosinusitis (CRS), the prevalence of ETD symptoms in the CRS population is poorly understood. We sought to determine the cross-sectional prevalence of ETD in patients with CRS using the validated Eustachian Tube Dysfunction Questionnaire (ETDQ-7) and to correlate ETDQ-7 scores with 22-item Sino-Nasal Outcome Test (SNOT-22) scores, endoscopy scores, and computed tomography (CT) scores. METHODS: A total of 101 patients with confirmed CRS completed the ETDQ-7 and SNOT-22 at their initial visit to our rhinology clinic...

This study aimed to determine whether nerve regeneration by means of an artificial nerve conduit is promoted by ethanol-induced cervical sympathetic ganglion block (CSGB) in a canine model. This study involved two experiments-in part I, the authors examined the effect of CSGB by ethanol injection on long-term blood flow to the orofacial region; part II involved evaluation of the effect of CSGB by ethanol injection on inferior alveolar nerve (IAN) repair using polyglycolic acid-collagen tubes. In part I, seven Beagles were administered left CSGB by injection of 99...

Transient receptor potential channel M5 (Trpm5)-expressing cells, such as sweet, umami, and bitter taste cells in the oropharyngeal epithelium, solitary chemosensory cells in the nasal respiratory epithelium, and tuft cells in the small intestine, that express taste-related genes function as chemosensory cells. Previous studies demonstrated that Skn-1a/Pou2f3, a POU homeodomain transcription factor is expressed in these Trpm5-expressing chemosensory cells, and is necessary for their generation. Trpm5-expressing cells have recently been found in trachea, auditory tube, urethra, thymus, pancreatic duct, stomach, and large intestine...

In patients with ileus with dilated intestine in imaging studies, endoscopic decompression appears a feasible option. However, its use is often uncritical and without scientific evidence. Before considering endoscopic intervention, CT-imaging should differentiate between mechanical obstruction and paralytic ileus/intestinal pseudo-obstruction. Tumor diagnosis and localisation are essential because the latter determines the choice of the decompression procedure. Coecal dilatation of more than 12 cm indicates an increased risk of perforation...

Our objective was to compare the efficacy of different lengths of rubber tube (6 French) on patients with esophageal stent implantation performed using a silk thread. We measured the effects in terms of pain and foreign body sensation felt in the pharynx and esophageal mucosa of the patients. A retrospective analysis was conducted using records of 65 patients who were divided into 3 groups. Group A had 20 cases with the distal end of the tube toward the nasal cavity, Group B had 21 cases with the distal end of the tube reaching the nasopharynx without exceeding the soft palate, and Group C had 24 cases with the distal end of the tube toward the upper end of the stent...

Young females undergoing thyroid surgery are apprehensive about the surgical scar. This leads to the introduction of Transoral Endoscopic Thyroidectomy (TOET). TOET is gaining popularity for its minimally invasive and cosmetically sound approach to perform thyroidectomies in young patients. The surgical site being the mouth orifice poses a challenge to the anaesthesiologist to secure a definitive airway. The case report is that of a young female undergoing TOET for whom we have successfully performed nasal intubation with a North Pole ivory endotracheal tube (ET)...

Possible complications of nasotracheal intubation include injury to the nasal or pharyngeal mucosa. Dissection of the retropharyngeal tissue by the endotracheal tube is one of the rarer of the more severe complications. Previous studies have indicated that the Parker Flex-Tip (PFT) tracheal tube (Parker Medical, Highlands Ranch, Colo) reduces the incidence of mucosal injury. We experienced a case involving inadvertent retropharyngeal placement of a PFT tube in a 29-year-old patient during nasotracheal intubation under general anesthesia for elective dental treatment...

Intestinal dysmotility is a major problem in critically ill patients. This report describes the successful treatment of intestinal dysmotility with rhubarb as a laxative in six critically ill patients on mechanical ventilation.. Bowel movement and defecation occurred in all patients an average of 1.8 days after the administration of powdered rhubarb. In 4 patients who also had gastric reflux, the reflux volume via nasal tube was decreased an average of 3.5 days after the initiation of rhubarb treatment, and enteral nutrition was able to be started...

Although radiation-based treatment for nasopharyngeal cancer may achieve excellent long term oncologic results, late effects of therapy may lead to soft tissue radionecrosis and velopharyngeal insufficiency (VPI). Repair of these oro- and nasopharyngeal defects presents a complex reconstructive challenge. We present a case of a long-term survivor treated with chemoradiotherapy for nasopharyngeal cancer who developed progressive dysphagia, velopharyngeal insufficiency, and radionecrosis of the nasopharynx and soft palate, leading to tracheostomy and gastrostomy tube dependence...

Oculoauriculovertebral spectrum, or Goldenhar Syndrome, is a condition characterized by variable degrees of uni- or bilateral involvement of craniofacial structures, ocular anomalies, and vertebral defects. Its expressivity is variable; therefore, the term "expanded Goldenhar complex" has been coined. The Goldenhar Syndrome usually involves anomalies in craniofacial structures, but it is known that nervous system anomalies, including encephalocele or caudal regression, may, rarely, occur in this condition. We report two rare cases of infants affected by Goldenhar Syndrome, associated with neural tube defects, specifically caudal regression syndrome and nasal encephaloceles, to underline the extremely complex and heterogeneous clinical features of this oculoauriculovertebral spectrum...

Despite a paradigm shift in anesthesia and trauma airway management, the craniomaxillofacial fracture (CMF) patients continue to pose a challenge. A prospective study was planned between April 2007 and March 2015 to investigate the safety, efficacy, utility, and complications of anterior submandibular approach for transmylohyoid intubation (TMI) in CMFs using an armored endotracheal tube (ETT). Out of 1,207 maxillofacial trauma cases reported, this study recruited 206 patients (152 males and 54 females) aged between 21 and 60 years...

REVIEW
Christian Guilleminault, Yu-Shu Huang
The upper airway is a collapsible tube, and its collapsibility increases during sleep. Extrinsic factors such as atypical craniofacial features may increase the risks of airway collapse. We review early development of oral-facial structures and the anatomical variants that may be present at birth and can impact nasal breathing. After birth, there is a continuous interaction between orofacial functions and growth of anatomic features. We review the dysfunctions identified to date that may impact orofacial development leading to sleep-disordered-breathing through changes in the orofacial growth...

Early, prehospital cooling seeks to reduce and control the body temperature as early as possible to protect the brain and improve patient outcome in cardiac arrest, stroke, and traumatic brain injury. In this study, we investigate the feasibility of localized cooling of the porcine brain by using a novel high-flow cold air protocol, which utilizes the close proximity between the nasal cavity and the brain. Five adult pigs were anesthetized and temperature change was mapped before, during, and after cooling by using the proton resonance frequency method on a 3 T Siemens Magnetom Skyra system...
