REVIEW
Mei Xu, Jia Luo
Heavy alcohol consumption has been associated with increased risk of several cancers, including cancer of the colon, rectum, female breast, oral cavity, pharynx, larynx, liver, and esophagus. It appears that alcohol exposure not only promotes carcinogenesis but also enhances the progression and aggressiveness of existing cancers. The molecular mechanisms underlying alcohol tumor promotion, however, remain unclear. Cancer stem cells (CSC), a subpopulation of cancer cells with self-renewal and differentiation capacity, play an important role in tumor initiation, progression, metastasis, recurrence, and therapy resistance...

According to the World Health Organization (WHO), almost 2 billion people each year are infected worldwide with flu-like pathogens including influenza. This is a contagious disease caused by viruses belonging to the family Orthomyxoviridae. Employee absenteeism caused by flu infection costs hundreds of millions of dollars every year. To successfully treat influenza virus infections, detection of the virus during the initial development phase of the infection is critical, when tens to hundreds of virus-associated molecules are present in the patient's pharynx...

Different eponyms such as "Wood syndrome," Meige syndrome, "Brueghel syndrome," "Blepharospasm plus syndrome" have been used to describe segmental craniocervical dystonias. These facial and/or oromandibular movement disorders are characterized by muscle contractions and spasms involving eyes, facial region, and sometimes pharynx, jaw, floor of the mouth, and tongue. The pathophysiology of craniocervical dystonia is poorly understood, but abnormal plasticity and impaired inhibition are suspected. Injection of botulinum toxin appears to be the best therapeutic option for treating segmental craniocervical dystonia...

Rocuronium is commonly used in preference to suxamethonium for rapid sequence induction in the Intensive Care Unit (ICU). We describe a patient who suffered significant neck trauma following a suicide attempt. On initial presentation to accident and emergency, he was an easy intubation with a Grade 1 view obtained at laryngoscopy. After surgery to repair his neck laceration, he was extubated and discharged from ICU. He later developed a severe aspiration pneumonia and required reintubation. After induction and paralysis with suxamethonium, the best view at laryngoscopy was a Grade 3 despite the use of different laryngoscopes...

Head and neck squamous cell carcinoma (HNSCC) encompasses tumors arising from several locations (oral and nasal cavities, paranasal sinuses, salivary glands, pharynx, and larynx) and currently stands as the sixth most common cancer worldwide. The most important risk factors identified so far are tobacco and alcohol consumption, and, for a subgroup of HNSCCs, infection with high-risk types of human papillomavirus (HPV). Despite several improvements in the treatment of these tumors in the last decades, overall survival rates have only improved marginally, mainly due to the advanced clinical stage at diagnosis and the high rates of treatment failure associated with this late diagnosis...

The taxonomic position of the endemic Antarctic species Enchodeloides signyensis (Loof, 1975), gen. n., comb. n. (= Enchodelus signyensis Loof, 1975) is discussed on the basis of morphological study, including SEM, morphometric data, postembryonic observations, and sequence data of 18S rDNA and the D2-D3 expansion fragments of the large subunit rDNA. A number of characters such as the cuticle and stoma structures, including the presence of moderately developed cuticularised ring around the oral aperture, peculiarities of pharynx expansion, size and position of the posterior pair of pharyngeal nuclei, a less complex uterus, and the position of a posterior ventromedian supplement show that this species differs substantially from the other members of the genus Enchodelus...

Adult extracardiac rhabdomyomas are rare benign mesenchymal tumor arising from skeletal muscle. While they are often located in the larynx and pharynx, the incidence in the parapharyngeal area is extremely rare with only 1 documented cytology case report to date. We report a case of an adult extracardiac rhabdomyoma in the parapharyngeal space diagnosed cytologically with subsequent histologic confirmation. The patient is a 57-year-old man with history of weight loss, hematuria, dysphagia, and airway encroachment...

An excellent understanding of the airflow structures is critical to enhance the efficiency of drug delivery via the human oral airway. The present paper investigates the characteristics of both steady and unsteady airflow structures in an idealized mouth-throat using large eddy simulation (LES). Representative inhalation flow rates of 15L/min at rest and 60L/min in exercise are considered. The study shows that there are more secondary vortices in the pharynx and the laryngeal jet is much longer and more concave in the steady flow field at 15L/min compared to the higher inspiration rate, which decreases the possibility of drug impinging on the wall...

OBJECTIVE: Pneumonia is most frequently produced by the microaspiration of flora that colonizes the oropharynx. Etiological diagnosis of pneumonia is infrequent in clinical practise and empirical treatment should be prescribed. The aims of the present study were to determine the factors associated with oropharynx colonization by uncommon microorganisms (UM) and to develop a predictive model. METHODS: A cross-sectional study that included all pa-tients living in one long-term care facilities was developed...

BACKGROUND: Adequate working space and a clear view for the dissected lesion are crucial for endoscopic submucosal dissection (ESD). Pharyngeal ESD requires that an otorhinolaryngologist creates working space by lifting the larynx with a curved laryngoscope. However, many countries do not have this kind of curved laryngoscope, and the devices could interfere with endoscope because of the narrow space of the pharynx. To overcome these issues, we used a transparent hood (Elastic Touch, slit and hole type, M (long), Top company, Tokyo Japan) instead of the curved laryngoscope to create adequate working space by pushing the larynx, and pharyngeal ESD could be done by gastroenterologists...

Edwardsiella tarda (E. tarda) is a rare pathogen in humans, especially during the peripartum period. Only a few cases of fatal neonatal infection with E. tarda have been reported. Herein, we describe a case of maternal septicemia caused by E. tarda following peripartum chorioamnionitis. The mother developed septic shock, disseminated intravascular coagulation and a post-cesarean wound hematoma with abscess. Her condition improved with multidisciplinary therapy including blood transfusion, antimicrobial agents, recombinant thrombomodulin and surgical debridement...

Arytenoid cartilage dislocation is a rare but curable cause of hoarseness and is commonly related to intubation or laryngeal trauma. We present a case of arytenoid cartilage dislocation without a traumatic event in a man who complained of acute hoarseness. An 82-year-old man visited our emergency department complaining of acute hoarseness. He had no history of general anesthesia or laryngeal trauma and had not caught a cold. He showed no abnormal physical findings including the pharynx. Examination using a laryngoscope revealed that the left vocal fold was fixed in the paramedian position...
