Jun Lu, Zhongtao Yang, Klaus Okkelberg, Maysam Ghovanloo
BACKGROUND: Tongue tracking, which helps researchers gain valuable insights into speech mechanism, has many applications in speech therapy and language learning. The wireless localization technique, which involves tracking a small magnetic tracer within the 3-D oral space, provides a low cost and convenient approach to capture tongue kinematics. In practice, this technique requires accurate calibration of 3-axial magnetic sensors used in the tracking system. The data-driven calibration depends on the trajectories of magnetic tracer and the ambient noise, which may change across time and space...

OBJECTIVE: Cancers found in the resected branchial cleft cyst are rare clinically but usually impose substantive diagnostic and treatment challenges for clinicians. METHODS: A 31-year-old man presented with a lateral neck mass that was suspected to be an inflammatory branchial cleft cyst. After excision, the pathologic specimen revealed a benign cystic appearance with a focus of undifferentiated carcinoma. Serologic tests for Epstein-Barr virus were negative. A positron emission tomography scan and upper aerodigestive tract endoscopies were negative for any other suspicious lesion...

BACKGROUND: Hypertrophy of the lingual tonsil tissue in the adult patient is thought to contribute to the pathophysiology of obstructive sleep apnea. The underlying etiology of lingual tonsil hypertrophy (LTH) in the adult patient is unclear and likely multifactorial. Previous studies have suggested that the lingual tonsils may undergo compensatory hyperplasia post-tonsillectomy in children, although it is unknown if this occurs or persists into adulthood. The purpose of this study was to determine what factors are associated with LTH in a population of Canadian adults...

REVIEW
Omar Ortega, Alberto Martín, Pere Clavé
Oropharyngeal dysphagia (OD) is a condition recognized by the World Health Organization and defined as the difficulty or inability to move a bolus safely and effectively from the oral cavity to the esophagus, and can include aspirations, choking, and residue. OD is pandemic among different phenotypes of older people, affecting between 27% and 91% of the population 70 years or older. Although OD can be diagnosed by well-defined clinical methods and complementary explorations, in the clinical setting OD is seldom systematically screened and treated, and awareness among the medical/geriatric community is scarce...

REVIEW
Hitoshi Maezawa
The tongue plays important roles in a variety of critical human oral functions, including speech production, swallowing, mastication and respiration. These sophisticated tongue movements are in part finely regulated by cortical entrainment. Many studies have examined sensorimotor processing in the limbs using magnetoencephalography (MEG), which has high spatiotemporal resolution. Such studies have employed multiple methods of analysis, including somatosensory evoked fields (SEFs), movement-related cortical fields (MRCFs), event-related desynchronization/synchronization (ERD/ERS) associated with somatosensory stimulation or movement and cortico-muscular coherence (CMC) during sustained movement...

OBJECTIVE: Morbidity associated with suspension laryngoscopy has been well documented. However, standard of care with regard to postoperative analgesia has not been described, and anecdotal evidence suggests wide variability with regard to postoperative narcotic and non-narcotic recommendations. We sought to quantify the postoperative course following suspension microlaryngoscopy by relating patient-based and intraoperative measures with analgesic use. METHODS: Body mass index (BMI), Friedman tongue position (FTP), and Mallampati scores as well as laryngoscope type, number of attempts required for optimal visualization, and suspension time were documented in 50 consecutive patients undergoing routine suspension microlaryngoscopy...

Chronic Lymphocytic Leukemia (CLL) is the most prevalent form of non-Hodgkin's lymphoma (NHL) in Western countries predominantly affecting adults over the age of 65. CLL is commonly indolent in nature but can present locally and aggressively at extranodal sites. Although CLL may commonly present with cervical lymphadenopathy, manifestation in nonlymphoid regions of the head and neck is not well described. CLL causing upper airway obstruction is even more uncommon. We describe a case of a patient with known history of CLL and stable lymphocytosis that developed an enlarging lymphoid base of tongue (BOT) mass resulting in rapid airway compromise...

Here we describe the superficial appearance of the brain of the rarely studied tree pangolin. Phylogenetic analyses have placed the pangolins, order Pholidota, as a sister group to the order Carnivora. The majority of features visible on the surface of the tree pangolin brain, and its overall appearance can be described as typically mammalian. The pattern of sulci and gyri, while simple, appears very similar to that observed in carnivores. Two derived features of the Pholidota were observed, the first being the rostral decussation of the pyramidal tract, which instead of occurring at the spinomedullary junction, decussates at the level of the caudal pole of the facial nerve nucleus in the rostral medulla oblongata...

Seneca Valley virus (SVV) is the causative agent of an emerging vesicular disease in swine, which is clinically indistinguishable from other vesicular diseases such as foot-and-mouth disease. In addition, SVV has been associated with neonatal mortality in piglets. While a commercial SVV qRT-PCR is available, commercial antibodies are lacking to diagnose SVV infections by immunohistochemistry (IHC). Thus, a novel in situ hybridization technique-RNAscope (ISH) was developed to detect SVVRNA in infected tissues...

Tracheostomy decannulation has always been considered a procedure with an attendant risk, especially in patients with a reduced upper airway diameter as is commonly observed in the obstructive sleep apnoea (OSA) population. We report on 4 cases where transoral robotic surgery (TORS) helped in the management of long-term cannulated patients. The aims of our paper are: 1. To demonstrate how the otolaryngology team can help identify patients at high risk for decannulation failure; and 2. To demonstrate how TORS may aid in the decannulation process of patients at high risk for failure due to severe tongue base hypertrophy...
