#1
Corinne Lawson, Mauria O'Brien, Maureen McMichael
Five dogs were presented with clinical signs compatible with upper airway obstruction, including stridor, stertor, coughing, gagging, and varying degrees of respiratory distress. All dogs had radiographic findings of soft tissue opacity in the area of the pharynx, larynx, or trachea, and several had narrowing of the tracheal lumen. Coagulation abnormalities (prolonged prothrombin time, activated partial thromboplastin time) were present in the four dogs that underwent testing. Four of five dogs were treated for the coagulopathy, presumably due to anticoagulant rodenticide toxicosis, and survived to discharge...

Infectious laryngotracheitis virus (ILTV) has a high affinity to replicate in the larynx and trachea causing severe lesions. Apart from the trachea, lack of knowledge exists on the ability of ILTV to replicate in other respiratory associated tissues. The objective of this study was to investigate how tissues that first encounter the virus dictate further sites of viral replication during the lytic stage of infection. Replication patterns of pathogenic strain 63140 and the chicken embryo origin (CEO) vaccine in conjunctiva, Harderian gland, nasal cavity and trachea were evaluated after ocular, oral, intranasal or intratracheal inoculation of specific pathogen free chickens...

Papillary squamous neoplasms of the upper respiratory tract are rare variants of squamous cell carcinomas. They are characterised by an exophytic, papillary growth and generally have favourable prognosis. The tumour has been described in the upper aerodigestive tract. In this context, most common sites of involvement are the larynx and hypopharynx, and rarely the oral cavity and oropharynx. The limited studies and small number of published cases of papillary squamous cell carcinoma of the palatine tonsil led us to make a complete analysis of this tumour by analysing the clinical, histological, radiological, virological and therapeutic aspects that are not always present in the literature...

BACKGROUND: Agricultural workers may be exposed to potential carcinogens including pesticides, sensitizing agents and solar radiation. Previous studies indicate increased risks of hematopoietic cancers and decreased risks at other sites, possibly due to differences in lifestyle or risk behaviours. We present findings from CanCHEC (Canadian Census Health and Environment Cohort), the largest national population-based cohort of agricultural workers. METHODS: Statistics Canada created the cohort using deterministic and probabilistic linkage of the 1991 Canadian Long Form Census to National Cancer Registry records for 1992-2010...

BACKGROUND AND AIMS: In the recent past, many novel devices such as AirTraq(®) and C-MAC(®) video laryngoscope (VL) have been introduced in an attempt to reduce anaesthetic morbidity and mortality associated with difficult intubation. In this study, we aimed to evaluate and compare C-MAC(®) VL with a standard Macintosh blade and the AirTraq(®) optical laryngoscope as a intubating devices with the patient's head in neutral position. METHODS: Sixty American Society of Anesthesiologist Physical Status I-II patients were randomly assigned to be intubated with C-MAC(®) VL (Group CM; n = 30) or AirTraq(®) (Group AT; n = 30) in the neutral position, with or without the application of optimization manoeuvres...

Radiotherapy (RT) is often the first choice of treatment for cancer of the larynx. Studies have shown that the incidence of carotid stenosis (CS) after radiotherapy of laryngeal cancer is increasing, and that gender difference in radiotherapy-induced side effects exist. Thus, we examined the gender difference in the incidence of CS and the impact of microinflammatory factors after radiotherapy. We reported this study on patients who received radiotherapy as part of the treatment for laryngeal cancer in the Jilin Province in China...

IgG4-related sclerosing disease of the larynx (IgG4-SD) is a recently described immunodependent systemic pathology characterized by diffusive or focal inflammatory infiltration of the affected organs and tissues by plasma cells expressing IgG4; it is accompanied by the subsequent development of obliterative phlebitis and fibrosclerosis associated with the increase of the serum IgG4 level. According to the recently published materials, the disease can also develop in the respiratory system. The present article describes the first documented case of IgG4-related sclerosing disease with the isolated lesion of the larynx...

OBJECTIVE: Laryngeal adductor response (LAR) to air puff is used as a reliable method in evaluating sensation thresholds (ST) in human laryngeal sensory disorders. This method has been difficult to perform in small subjects such as rodents. The aims of this study were to 1) evaluate ST to air puff under binocular microlaryngoscopy in rats to evaluate laryngeal sensory disorders, 2) determine sensory thresholds at varying target locations, and 3) determine the ideal depth of anesthesia...

Head and neck squamous cell carcinoma is the sixth most common cancer diagnosed worldwide and the eighth most common cause of cancer death. Malignant tumors of the oral cavity, oropharynx, and larynx can be treated by surgical resection or radiotheraphy with or without chemotheraphy and have a profound impact on quality of life functions, including swallowing. When surgery is the chosen treatment modality, the patient may experience swallowing impairment in the oral and pharyngeal phases of deglutition. A videofluoroscopic study of swallow enables the morphodynamics of the pharyngeal-esophageal tract to be accurately examined in patients with prior surgery...

Drug-induced sedation endoscopy (DISE) classification systems play a significant role in clinical analysis based on DISE findings, treatment decision process, treatment planning process and fundamentally in treatment outcomes. However, there is a major problem: there is no universally agreed DISE classification system. Hence, for the same DISE examination different DISE classification systems can be used to: assess anatomic findings, decide and plan different treatments. Hence, this leads to different treatment outcomes...

BACKGROUND: Adenoid cystic carcinoma (ACC) of the larynx and trachea is very rare. CASE: A 45-year-old man with ACC of the larynx presenting as a thyroid mass is reported in this study. Physical examination revealed a large solid thyroid nodule in the left lobe without any lymphadenopathy. A technetium thyroid scan showed multinodular goiter with cold nodules in the left lobe, isthmus, and functioning nodules in the right lobe. A large thyroid mass originating from the left side of the larynx, mostly the left vocal cord and the infraglottic part, was seen using enhanced magnetic resonance imaging after rupture of the thyroid cartilage on the left side...

The prognosis and survival of patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC) are related to the clinical staging. Tumor growth and metastasis are closely related to angiogenesis. Vascular endothelial growth factor (VEGF) and cyclooxygenase 2 (COX-2) are intimately related to the angiogenic process in which the blood supply required for neoplastic evolution is ensured. Considering the contributions of VEGF and COX-2 to the formation, growth, and progression of primary tumors, as well as their metastasis, it has been thought that the expression of these two factors might be related to the size and/or aggressiveness of laryngeal and hypopharyngeal cancer...

PURPOSE: Surgery, chemo- and/or external radiation therapy are the standard therapy options for the treatment of laryngeal cancer. Trans-oral access for the surgery reduces traumata and hospitalization time. A new trend in treatment is organ-preserving surgery. To avoid regrowth of cancer, this type of surgery can be combined with radiation therapy. Since external radiation includes healthy tissue surrounding the cancerous zone, a local and direct intraoral radiation delivery would be beneficial...
