Lemierre's syndrome is a rare and feared complication of pharyngitis, occurring most commonly in adolescents and young adults. It is typically defined by the constellation of septic internal jugular vein thrombophlebitis, pulmonary and other septic emboli, and sterilesite infection by Fusobacterium necrophorum. The rarity and severity of Lemierre's syndrome has made it an attractive subject for case reports but there is a paucity of evidence to inform areas of persistent uncertainty. In recent years, heightened attention and controversy has focused upon speculation that a purported rise in the incidence of Lemierre's syndrome is due to reduced antibiotic prescribing for respiratory tract infections, that F...

BACKGROUND AND OBJECTIVE: We investigated the swallowing function in patients with Parkinson's disease (PD) using deteriorated tongue control because PD patients frequently exhibit an impaired oral stage of swallowing and the tongue movement affects to oral and pharyngeal stage. METHODS: In total, 201 PD patients (106 men, 95 women; mean age 70.6 ± 8.0 years; median Hoehn-Yahr Stage III) were studied. The patients swallowed 10 mL of liquid barium under videofluorography and their oral transit time (OTT) was measured...

BACKGROUND: Cricopharyngeal myotomy is a treatment for obstructive cricopharyngeal bar and Zenker's diverticulitis. Little is reported regarding contrast study findings and their correlation with patient symptoms. METHODS: All patients treated by cricopharyngeal myotomy underwent a preoperative and postoperative videofluoroscopic swallow study (VFSS) and completed the self-reported Eating Assessment Tool (EAT-10). Studies were analyzed quantitatively. RESULTS: Forty cricopharyngeal myotomies were performed (mean age 76 years; SD 8...

This study aimed to evaluate the effect of effortful swallow combined with surface electrical stimulation as a form of resistance training on pharyngeal constriction function in post-stroke patients with dysphagia. Nineteen patients post-stroke with dysphagia received 20 minutes effortful swallow training with resistive electrical stimulation for 5 days per week for 4 weeks. Electrical stimulation was applied on the infrahyoid area as resistance against hyoid elevation. Stimulation intensity was adjusted daily up to the maximum tolerable level of the participant...

Streptococcus pyogenes, or group A Streptococcus, is a pathogen responsible for a wide range of clinical manifestations, from mild skin and soft tissue infections and pharyngitis to severe diseases. Its epidemiological characteristics should be comprehensively under surveillance for regulating the national prevention and treatment practice. Herein, a total of 140 S. pyogenes, including 38 invasive and 102 noninvasive isolates, were collected from infected patients in 10 tertiary general hospitals from 7 cities/provinces in China during the years 2009-2016...

The short-stature homeobox-containing gene (SHOX) was originally discovered as one of genes responsible for idiopathic short-stature syndromes in humans. Previous studies in animal models have shown the evolutionarily conserved link between this gene and skeletal formation in early embryogenesis. Here, we characterized developmental roles of shox/SHOX in zebrafish embryos and human mesenchymal stem cells (hMSCs) using loss-of-function approaches. Morpholino oligo-mediated knockdown of zebrafish shox markedly hindered cell proliferation in the anterior region of the pharyngula embryos, which was accompanied by reduction in the dlx2 expression at mesenchymal core sites for future pharyngeal bones...

The tongue can move freely and is important in oral motor functions. Tongue movement must be coordinated with movement of the hyoid, mandible, and pharyngeal wall, to which it is attached. Our previous study using isolated brainstem-spinal cord preparations showed that application of N-methyl-D-aspartate induces rhythmic activity in the hypoglossal nerve that is coincident with rhythmic activity in the ipsilateral trigeminal motor nerve. Partial or complete midline transection of the preparation only abolishes activity in the trigeminal motor nerve; therefore, the neuronal network contributing to coordinated activity of the jaw/tongue muscles is located on both sides of the preparation and sends motor commands to contralateral trigeminal motoneurons...

We investigated whether men who have sex with men (MSM) would use mouthwash daily to prevent pharyngeal gonorrhoea. Ten MSM attending the Melbourne Sexual Health Centre were asked to use a Listerine(®) alcohol-containing mouthwash daily for 14 days in August 2015. Mouthwash was used at least once daily for 133 of 140 person-days (95% of days; 95% confidence interval 90-98%). All 10 men were willing to use mouthwash on a daily basis, and nine men were willing to use mouthwash after oral sex. This study showed that daily use of mouthwash is an acceptable intervention to prevent pharyngeal gonorrhoea in MSM...

BACKGROUND: Recent technological advances incorporated in high resolution manometry have justifiably heightened interest in manometric evaluation of the pharynx. Despite this interest, from both physiologic and clinical perspective there remain a number of unanswered questions regarding the magnitude of variability of pharyngeal pressure phenomena. Therefore, the aim of the present study was to characterize in healthy individuals the inter-subject and recording-site specific variability of pharyngeal peristaltic pressure phenomena...

REVIEW

Obstructive sleep apnea (OSA) is a heterogeneous disorder. If left untreated, OSA has major health, safety and economic consequences. In addition to varying levels of impairment in pharyngeal anatomy (narrow/collapsible airway), non-anatomical 'phenotypic traits' are also important contributors to OSA for most patients. However, the majority of existing therapies only target the anatomical cause (e.g. continuous positive airway pressure [CPAP], oral appliances, weight loss, positional therapy, and upper airway surgery)...

Neonates have greater morbidity/mortality from lower respiratory tract infections (LRTI) compared to older children. Lack of conditioning of the pulmonary immune system due to limited environmental exposures and/or infectious challenges likely contributes to the increase susceptibility in the neonate. In this study, we sought to gain insights into the nature and dynamics of the neonatal pulmonary immune response to LRTI using a murine model. METHODS: Wildtype (WT) and Ccr2(-/-) C57BL/6 neonatal and juvenile mice received E...

Although angioneurotic oedema (AE) is a rare entity, it sometimes leads to devastating consequences. We report the case of an oro-pharyngeal angioneurotic attack following the initiation of a fibrinolysis therapy by alteplase and relay by heparin in a patient with severe acute pulmonary embolism. In view of this original case, we propose to highlight the most recent elements concerning the physiopathology of this disease.

Amyloidomas are rare tumor-like depositions of abnormally folded, insoluble proteins that may be seen in the setting of systemic amyloidosis or as isolated tumoral deposits. Focal, isolated amyloidomas carry an excellent prognosis whereas systemic amyloidoses do not. The ability to identify or suggest amyloidoma on imaging studies may help direct laboratory testing and eventual diagnosis. Amyloidomas involving the head and neck have been variably described from homogeneously T2 hypointense to iso-slightly hyperintense relative to skeletal muscle...

Enterovirus D68 has been associated with a poliomyelitis-like illness, notably during an outbreak in 2014, and particularly affecting children in the USA. We report a case of acute segmental flaccid paralysis with respiratory involvement in an adult in the UK, with enterovirus D68 detected in a sputum sample. MR imaging of cervical spinal cord showed a longitudinally extensive T2 hyperintensity in the anterior cord. Cerebrospinal fluid showed an elevated white cell count, predominantly lymphocytic, with otherwise normal constituents and negative viral PCRs...

Cranial neural crest cells are a multipotent cell population that generate all the elements of the pharyngeal cartilage with differentiation into chondrocytes tightly regulated by temporal intracellular and extracellular cues. Here, we demonstrate a novel role for miR-27, a highly enriched microRNA in the pharyngeal arches, as a positive regulator of chondrogenesis. Knock down of miR-27 led to nearly complete loss of pharyngeal cartilage by attenuating proliferation and blocking differentiation of pre-chondrogenic cells...

OBJECTIVE: The aim of this study was to analyze the topographical structures of the muscles surrounding the Eustachian tube. MATERIALS AND METHODS: We conducted macroscopic and histological studies of 24 halves of 12 heads from Japanese cadavers. RESULTS: The main findings were as follows: 1) the infero-lateral muscle bundles of the tensor veli palatini didn't turn medially at the pterygoid hamulus but were distributed laterally and continuous with the buccinator; 2) the tensor veli palatini attached laterally to the membranous part of the Eustachian tube; 3) the superior pharyngeal constrictor was not only adjacent to the buccinator at the pterygomandibular raphe but also had muscular continuation with it laterally and 4) some bundles of the superior pharyngeal constrictor adhered with the palatine aponeurosis...
