Strongyluris oscari Travassos, 1923, parasite of Topidurus torquatus (Wied-Neuwied, 1820) (Tropiduridae) from Brazil and Pharyngodon mamillatus (Linstow, 1897) of Chalcides ocellatus (Forskal, 1775) (Scincidae) from Egypt, were redescribed based on light and scanning electron microscopy, and re-evaluation of specimens from parasitological collections. The following features were accurately observed in S. oscari for the first time: structure of lips and pharyngeal valve, presence and distribution of somatic papillae, number and arrangement of caudal papillae, presence of inner sclerotised structures supporting the ventral sucker and the ventral region in tail of males, and structure of the posterior anal lip in females...

AIM: To find out if subjects with 22q11.2 deletion syndrome (DS) have a different velopharyngeal anatomy which could cause velopharyngeal insufficiency (VPI). METHODS: A prospective study of 16 subjects >16 years of age with 22q11.2 DS, without overt cleft palate and without previous VPI surgery, and 48 healthy controls >18 years of age were included in the study. Speech was recorded and scored blindly by two independent senior speech therapists. All 64 individuals had MRI scans, which were analyzed blindly by a consultant radiologist...

Posterior pharyngeal wall squamous cell carcinomas (SCCs) are rare and have an associated poor prognosis. Progress in transoral resection techniques, in particular, transoral robotic surgery (TORS), have renewed the role of surgery in their treatment. This article presents the oncological and functional results obtained by the French Group of Head and Neck Robotic Surgery for TORS for posterior pharyngeal wall SCC-curative surgery. This retrospective, multicentre study presents data collected between September 2009 and November 2013 for patients treated with TORS for posterior pharyngeal wall SCCs...

A 33-year-old African-American woman recently diagnosed with severe idiopathic gastroparesis was readmitted for hypoxic respiratory failure secondary to aspiration pneumonia. A fiber-optic endoscopic evaluation of swallow study revealed severe pharyngeal dysphagia. Brain magnetic resonance imaging showed an ill-defined lesion in the posterior aspect of the medulla concerning for a demyelinating process. Serum neuromyelitis optica immunoglobulin G returned positive. Neuromyelitis optica treatment resulted in the patient's clinical improvement...

BACKGROUND: Vertebrate head development depends on a series of interactions between many cell populations of distinct embryological origins. Cranial mesenchymal tissues have a dual embryonic source: - the neural crest (NC), which generates most of craniofacial skeleton, dermis, pericytes, fat cells, and tenocytes; and - the mesoderm, which yields muscles, blood vessel endothelia and some posterior cranial bones. The molecular players that orchestrate co-development of cephalic NC and mesodermal cells to properly construct the head of vertebrates remain poorly understood...

A retropharyngeal abscess is a collection of pus located behind the posterior pharyngeal wall. Main symptoms include torticoli, pyrexia and odynodysphagia. It can be secondary to upper airway infections, pharyngeal penetrating trauma or idiopathic. Complications are rare, but may be life-threatening due to airway obstruction or infection's spread to the surrounding structures. Surgery is conducted in case of abscess > 2 cm on CT scan images, complication or worsening of the symptoms. This article presents a clinical case with literature review...

BACKGROUND: En bloc excision of cervical chordoma is a technically complex procedure, due to the involvement and closeness of the tumor to the spinal cord, cervical nerve roots, and vertebral arteries. Studies have previously shown that en bloc excision of chordomas with negative margins improves local control and prolongs disease-free survival compared with intralesional excision. True en bloc spondylectomy in the cervical spine is not feasible since bilateral vertebral artery sacrifice is not possible...

Here, we discuss a case of carotid blowout syndrome successfully treated with endovascular parent artery occlusion. A 71-year-old woman underwent treatment for esophageal cancer resection, followed by 50-Gy radiotherapy, 19 years prior. Due to local recurrence, she underwent 66- and 72-Gy radiation treatments at 2 and 4 years after the initial treatment, respectively. Afterward, tracheostomy and enterostomy were performed. This time, she was transported to our emergency department because of acute eruptive bleeding from the tracheal tube...

Laryngeal granulomas are benign lesions located in the posterior third of the glottis, mainly at the level of the vocal apophysis of the arytenoid cartilage. They are typically associated with three etiological factors: endotracheal intubation, inappropriate voice use and/or gastroesophageal reflux. The formation of a post-intubation laryngeal granuloma is a late complication related to intubation injury. It is uncommon in the child, especially if the period of intubation is short. It is usually unilateral and produces dysphonia, pharyngeal foreign body sensation and cough...

BACKGROUND: Free jejunal transfer has a high success rate, but if vascular thrombosis occurs, the salvage of failing flap with reanastomosis is difficult. This study described a combined deltopectoral (DP) and pectoralis major musculocutaneous (PMMC) flap 2-step technique for cervical esophageal reconstruction after free-jejunal-flap necrosis. METHODS: In step 1, the detection of free jejunal flap with the subsequent debridement of necrotic and infected tissue was followed by the construction of external fistula on the pharyngeal side with the hole in cervical skin and the construction of another external fistula on the esophageal side and tracheal stoma with a single or double DP flap...

BACKGROUND: A professional singer produced various vowels on a comfortable loudness and pitch in an inspiratory and expiratory phonation manner. The present study investigates the morphological differences and tries to find a link with the acoustical characteristics. OBJECTIVES/HYPOTHESIS: We hypothesize that features, constantly present over all vowels, characterize inhaling phonation and that the formant frequencies reflect the morphological findings. STUDY DESIGN: A prospective case study was carried out...

Fish predation is important in shaping populations and community structure in aquatic systems. These predator-prey interactions can be influenced by environmental, behavioural and morphological factors. Morphological constraints influence the feeding performance of species, and interspecific differences can thus affect patterns of resource use. For piscivorous fishes that swallow prey whole, feeding performance has traditionally been linked to three key morphological constraints: oral gape, pharyngeal gape, and the cleithral gape...

BACKGROUND: The cranio-cervical junction is a rare location for spinal dural arteriovenous fistulas (dAVF). Typically, fistulas at this location present with findings related to intracranial cortical venous reflux or with cervical myelopathy. We present a case of cranio-cervical junction dAVF with isolated clinical and radiographic findings of thoracolumbar myelopathy.

OBJECTIVE: In this study, we evaluated pathological changes in the tooth and pharynx of GERD rats to elucidate the association between gastric acid reflux and oral and pharyngeal diseases. METHODS: An experimental rat model of chronic acid reflux esophagitis was surgically created. The oral cavities were observed histologically every 2 weeks until 20 weeks after surgery. RESULTS: At 10 weeks after surgery, molar crown heights in GERD rats were shorter than that in control rats, and inflammatory cell infiltration by gastric acid reflux was found in the periodontal mucosa of GERD rats...

The oral cavity and oropharynx have historically been viewed as a single anatomic compartment of the head and neck. The practice of combining the oral cavity and oropharynx has recently been revised, largely owing to the observation that human papillomavirus (HPV)-related carcinogenesis has a strong predilection for the oropharynx but not the oral cavity. The purpose of this study was to determine whether HPV is evenly distributed across squamous cell carcinomas of the oropharynx including those sites that do not harbor tonsillar tissues such as the soft palate...

Kingella kingae is an important pathogen in young children and initiates infection by colonizing the posterior pharynx. Adherence to pharyngeal epithelial cells is an important first step in the process of colonization. In the present study, we sought to elucidate the interplay of type IV pili (T4P), a trimeric autotransporter adhesin called Knh, and the polysaccharide capsule in K. kingae adherence to host cells. Using adherence assays performed under shear stress, we observed that a strain expressing only Knh was capable of higher levels of adherence than a strain expressing only T4P...

BACKGROUND: Fiberoptic bronchoscope-guided tracheal intubation is the gold standard for managing patients with supraglottic growths. In infants with a large and overhanging epiglottis, the success of fiberoptic-guided intubation relies heavily on the available space between the inferior surface of the epiglottis and the posterior pharyngeal wall or, more specifically, the superior surface of the supraglottic growth. CASE REPORT: We describe the inability to negotiate the tip of the fiberscope between the epiglottis and the supraglottic growth and the successful use of direct laryngoscopy to improve the available space along with the usefulness of "bubbling of air" to locate the glottic opening in an infant...

Clinically, in young immunocompetent adults, Epstein-Barr virus (EBV) usually manifests as infectious mononucleosis (IM). Typical clinical findings of EBV IM include fever, profound fatigue, pharyngitis, bilateral posterior cervical adenopathy, and splenomegaly. Respiratory involvement with EBV IM may occur, but is distinctly rare. We present a case of a 20 year old female who with classic EBV IM, but was inexplicably dyspneic and hypoxemic. Further diagnostic testing confirmed co-infection with Mycoplasma pneumoniae...

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 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)...
