Eagle syndrome and carotid artery dissection: a rare skull base cause of stroke.

Eagle's syndrome is a rare collection of symptoms that occur secondary to an elongated styloid process or calcified stylohyoid ligament irritating its surrounding structures. Classically, this presents as unilateral throat pain or rarely, as acute neurological symptoms secondary to compression of the internal carotid artery: so called 'stylocarotid syndrome'. Significant neurological events in teenagers, secondary to Eagle syndrome have not been reported. We discuss the rare case of a teenage boy, diagnosed with right internal carotid artery dissection and middle cerebral artery infarction, with no cause initially identified. Following further admission with a transient neurological episode, he was noted to have elongated styloid processes with the right abutting the site of carotid dissection. He underwent styloidectomy and has since remained symptom free. This case highlights the importance of considering anatomical variants when assessing young patients with neurological symptoms, and the potential morbidity and mortality benefit that early surgical intervention may have.

Cervical Nodal Metastatic Pituitary Carcinoma: A Case Report.

Pituitary carcinomas are rare tumors with only 170 cases reported in the literature.1 They form a very small proportion of pituitary tumors, which are commonly benign adenomas. Metastatic disease diagnosed by fine needle aspiration cytology is extremely rare and has only been reported in 6 patients,2-5 3 of whom had cervical nodal metastases, with other sites of metastases being the liver and cervical vertebra. We report a case of cervical metastatic pituitary carcinoma diagnosed by core needle biopsy.

Multiple Upper Aerodigestive Tract Masses Presenting With Stridor-A Rare Case of Aggressive Multifocal Extramedullary Plasmacytoma.

Extramedullary plasmacytomas represent a rare group of B-cell malignancies that arise outside the bone marrow and their disease process is still poorly understood. Here, we will describe a case of a 76-year-old patient who presented with a large chest wall and subglottic mass causing airway compromise and stridor. Biopsies showed atypical plasma cells with prominent nucleoli which were in keeping with an extramedullary plasmacytoma. Disease progressed despite surgical debulking, targeted radiotherapy, and multiple chemotherapy regimens. Although response to treatment is classically good, patients occasionally present with aggressive disease.

Endoscopic removal of ectopic dentition in ethmoid sinus.

A 66-year-old woman presented with a 6-month history of unilateral right nasal obstruction and rhinorrhoea not responding to medical therapy. She had a history of dental implantation for an unerupted tooth on the right side 3 years ago. Physical examination including flexible nasendoscopy demonstrated yellow debris in the right middle meatus. CT paranasal sinuses demonstrated a radiopaque lesion in the right anterior ethmoid sinus and resembled the unerupted tooth. The tooth was removed endoscopically from the right nasal cavity without complications. This case highlights the importance of eliciting an accurate dental history and considering ectopic dentition as a differential diagnosis in a patient with unilateral symptoms of sinusitis.

Survival outcomes for head and neck cancer patients with N3 cervical nodal metastases.

BACKGROUND: Management of metastatic N3 nodal disease from primary head and neck squamous cell carcinoma (HNSCC) is controversial. Recently, there has been a move to observation of the neck for those who achieve complete response (CR) after chemoradiotherapy (CRT). We sought to determine survival outcomes for N3 nodal disease, particularly for patients with human papilloma virus (HPV)-positive HNSCC. METHODS: We carried out a systematic search of MEDLINE and Embase for articles between 01/2008 and 12/2017. Articles on N3 nodal disease in HNSCC patients treated with CRT or surgery + adjuvant RT/CRT were included if they reported on oropharyngeal or HPV+ subgroups. Local control (LC), nodal control (NC), distant metastasis-free survival (DMFS), disease-free survival (DFS) or overall survival (OS) was assessed. RESULTS: Nine studies met the inclusion criteria. Eight of these studies (N = 5304) allowed further comparison: 4 were on CRT, 2 on surgery + RT/CRT and 2 on both. Four of these eight studies and the remaining included study reported on residual nodal disease on histology after neck dissection (ND) following CRT. Patients treated with CRT achieved LC rates of 77%-94% at 2-3 years; those who had a CR had LC of >90%. Better NC was noted in patients who achieved a CR. Three-year OS was better for HPV+ HNSCC (range, 55.2%-81%). Patients with CR had better survival outcomes (DMFS 77% at 3 years vs 69.8% for HPV+; OS 68.9% at 3 years vs 55.2% for HPV+). Primary surgery demonstrated similar survival for HPV+ vs HPV- and better survival in oropharyngeal cancers. Five-year DFS rates varied from 30% to 87%, and OS from 26.6% to 84%. For patients with non-CR, positive histology rates varied from 27.3% to 100%, with average positive histology rates of 27.3% in HPV+ patients with non-CR vs 60% for HPV- patients with non-CR. CONCLUSION: The current literature does not support the de-escalation of treatment with HPV- N3 disease. Observation of HPV+ patients who achieve a CR post-CRT is reasonable but further prospective studies are required given the heterogeneity and risk of bias within these current studies. Planned ND should remain standard of care for non-CR cohort.

Prosthetic reconstruction of the trachea: A historical perspective.

This review discusses the history of tracheal reconstruction; from early work to future challenges. The focus is primarily on prosthetic tracheal reconstruction in the form of intraluminal stents, patch repairs, circumferential repairs and replacement of the trachea. A historical perspective of materials used such as foreign materials, autografts, allografts, xenografts and techniques, along with their advantages and disadvantages, is provided.

When continuous positive airway pressure (CPAP) fails.

Obstructive sleep apnoea (OSA) is increasingly prevalent, particularly in the context of the obesity epidemic, and is associated with a significant social, health and economic impact. The gold standard of treatment for moderate to severe OSA is continuous positive airway pressure (CPAP). However compliance rates can be low. Methodology to improve patient tolerance to CPAP alongside with alternative, non-surgical and surgical, management strategies are discussed. All patients that fail CPAP therapy would benefit from formal upper airway evaluation by the otolaryngologist to identify any obvious causes and consider site-specific surgical therapies. Patient selection is integral to ensuring successful outcomes. A multidisciplinary team is needed to manage these patients.

Otorhinolaryngological aspects of sleep-related breathing disorders.

Snoring and obstructive sleep apnoea (OSA) are disorders within a wide spectrum of sleep-related breathing disorders (SRBD). Given the obesity epidemic, these conditions will become increasingly prevalent and continue to serve as a large economic burden. A thorough clinical evaluation and appropriate investigations will allow stratification of patients into appropriate treatment groups. A multidisciplinary team is required to manage these patients. Patient selection is critical in ensuring successful surgical and non-surgical outcomes. A wide range of options are available and further long term prospective studies, with standardised data capture and outcome goals, are required to evaluate the most appropriate techniques and long term success rates.

Driving towards obesity: a systematized literature review on the association between motor vehicle travel time and distance and weight status in adults.

BACKGROUND: Higher levels of sedentary behavior are associated with adverse health outcomes. Over-reliance on private motor vehicles for transportation is a potential contributor to the obesity epidemic. The objective of this study was to review evidence on the relationship between motor vehicle travel distance and time and weight status among adults. METHODS: Keywords associated with driving and weight status were entered into four databases (PubMed Medline Transportation Research Information Database and Web of Science) and retrieved article titles and abstracts screened for relevance. Relevant articles were assessed for their eligibility for inclusion in the review (English-language articles a sample ≥ 16 years of age included a measure of time or distance traveling in a motor vehicle and weight status and estimated the association between driving and weight status). RESULTS: The database search yielded 2781 articles, from which 88 were deemed relevant and 10 studies met the inclusion criteria. Of the 10 studies included in the review, 8 found a statistically significant positive association between time and distance traveled in a motor vehicle and weight status. CONCLUSIONS: Multilevel interventions that make alternatives to driving private motor vehicles more convenient, such as walking and cycling, are needed to promote healthy weight in the adult population.

Management and prognosis of primary tracheal cancer: a national analysis.

OBJECTIVES/HYPOTHESIS: To perform a national review of the incidence and treatment of primary tracheal cancer and to identify gaps in service provision and factors associated with survival. STUDY DESIGN: Retrospective analysis of Hospital Episode Statistics data for England between 1996 and 2011. METHODS: Information about age, sex, morbidity, provider trust, diagnostic delay, nature of hospital admission and treatment, and palliation-free survival were recorded. The relationship between variables and survival was explored with Cox regression. RESULTS: There were 874 patients, giving an incidence of 0.9 per million. Mean age at diagnosis was 66 ± 13, and there were 456 (52%) males. Mean presentation to diagnosis latency was 2.5 ± 8 months, and 40% of patients presented as emergency admissions. There were 19 cases of oesophageal involvement and 241 cases of bronchopulmonary involvement; and 188 patients developed distant metastases. There were 60 curative resections (6.9%), which was the most significant predictor of palliation-free survival (hazard ratio: 0.23; 95% confidence interval 0.13-0.38). Other prognostic variables included age, sex, emergency admission, interventional bronchoscopy, chemotherapy, oesophageal involvement, and distant metastases. Ten-year palliation-free survival was 60.8% with curative resection and 19.5% overall. Eighty-six percent of patients were treated in units that treated fewer than one patient per year. CONCLUSION: Tracheal cancer is under-recognized and under-treated. Early diagnosis, access to interventional bronchoscopy, and surgical treatment in specialist units may improve the survival of patients with this condition.

Preoperative superselective mesenteric angiography and methylene blue injection for localization of obscure gastrointestinal bleeding.

Localizing obscure gastrointestinal bleeding can be a clinical challenge, despite the availability of various endoscopic, imaging, and visceral angiographic techniques. We reviewed the management of patients presenting with obscure gastrointestinal bleeding during the period from 2005 to 2011. Four patients had preoperative localization of the bleeding site with superselective mesenteric angiography, which was confirmed by the use of intraoperative methylene blue injection. This novel technique allowed us to identify the abnormal pathology, and, consequently, resection of the implicated segment of small bowel was performed without any postoperative complications. Final histology showed that 2 patients had arteriovenous malformations: one had a benign hemangioma of the small bowel, and the other had chronic ischemic ulceration in the ileum. Superselective mesenteric angiography combined with intraoperative localization with methylene blue is an important and innovative technique in the management of patients with unclear sources of gastrointestinal bleeding and allows for effective hemorrhage control with a focused and therefore limited bowel resection.

Role of thoracotomy and metastatectomy in gestational trophoblastic neoplasia: a single center experience.

Gestational trophoblastic neoplasia (GTN) is a rare collection of malignancies which are usually curable with modern chemotherapy. Lung metastasis is a relatively common feature of these malignancies and is not considered an adverse prognostic feature. Occasionally, however, the management of these patients necessitates adjuvant thoracic surgery, either to establish the diagnosis or to potentially provide a curative resection of drug-resistant foci of disease. This case series highlights 5 such cases in which thoracic surgery has significantly contributed to the management and outcome of complicated GTN patients, and suggests when thoracic surgery should be considered in this rare group of patients.
