Immunological profiling of key inflammatory drivers of nasal polyp formation and growth in chronic rhinosinusitis.

BACKGROUND: Chronic rhinosinusitis (CRS) is a chronic inflammatory condition of the upper airways, often associated with the formation of nasal polyps (CRSwNP). It is well established that macroscopically normal (non-polypoidal) sinonasal mucosa in CRSwNP patients can undergo polypoidal change over time, turning into frank polyps. However, little is known about what drives this process. This study aimed to investigate potential drivers of nasal polyp formation or growth through comparison of the immunological profiles of nasal polyps with contiguous non-polypoidal sinonasal mucosa, from the same patients. METHODS: The immune profiles of three types of tissue were compared; nasal polyps and adjacent non-polypoidal sinonasal mucosa from 10 CRSwNP patients, and sinonasal mucosa from 10 control patients undergoing trans-sphenoidal pituitary surgery. Nasal polyp and control samples were also stimulated with Staphylococcus aureus enterotoxin B (SEB) using a nasal explant model, prior to cytokine analysis. Real time quantitative polymerase chain reaction (IL-5, T-bet, IL-17A, FoxP3, TLR-4, IL-8, IL-1beta and IL-6) and Luminex (IFNgamma, IL-5 and IL-17A) were used to quantify pro-inflammatory responses. RESULTS: Nasal polyps and contiguous non-polypoidal sinonasal mucosa from CRSwNP patients displayed a very similar pro-inflammatory profile. When stimulated with SEB, nasal polyps displayed a Th2/Th17 mediated response when compared to controls. CONCLUSIONS: In CRSwNP, nasal polyps and non-polypoidal sinonasal mucosa from the same patient displayed a similar pro-inflammatory profile skewed towards the Th2/Th17 pathway in nasal polyps following SEB stimulation, with evidence of disordered bacterial clearance. These factors may contribute to enhanced survival of bacteria and development of a chronic inflammatory milieu, potentially driving new polyp formation and recurrence following surgical removal.

Patient reported outcome measures in septorhinoplasty surgery.

INTRODUCTION: Surgical procedures incorporating a cosmetic element such as septorhinoplasty and otoplasty are currently under threat in the National Health Service (NHS) as they are deemed to be procedures of 'limited clinical benefit' by many primary care providers. Patient reported outcome measures (PROMs), which assess the quality of care delivered from the patients' perspective, are becoming increasingly important in documenting the effectiveness of such procedures. METHODS: The Rhinoplasty Outcomes Evaluation (ROE) questionnaire, a validated PROM tool, was used to assess patient satisfaction in 141 patients undergoing septorhinoplasty surgery over a 90-month period at the University Hospital Southampton NHS Foundation Trust. RESULTS: Overall, 100 patients with a mean follow-up period of 36 months completed the study. The mean ROE score was 73.3%. In addition, 75% of patients questioned were happy with the final result of their operation and 83% would undergo the procedure again if required. These benefits occurred irrespective of age, sex and primary versus revision surgery, and were maintained for up to 71 months following surgery. CONCLUSIONS: This study has shown that patients are generally satisfied with their functional and cosmetic outcomes following septorhinoplasty surgery. These results help support the case for septorhinoplasty surgery to continue being funded as an NHS procedure.

YouTube as a source of information on rhinosinusitis: the good, the bad and the ugly.

OBJECTIVE: YouTube is an internet-based repository of user-generated content. This study aimed to determine whether YouTube represented a valid and reliable patient information resource for the lay person on the topic of rhinosinusitis. METHODS: The study included the first 100 YouTube videos found using the search term 'sinusitis'. Videos were graded on their ability to inform the lay person on the subject of rhinosinusitis. RESULTS: Forty-five per cent of the videos were deemed to provide some useful information. Fifty-five per cent of the videos contained little or no useful facts, 27 per cent of which contained potentially misleading or even dangerous information. Videos uploaded by medical professionals or those from health information websites contained more useful information than those uploaded by independent users. CONCLUSION: YouTube appears to be an unreliable resource for accurate and up to date medical information relating to rhinosinusitis. However, it may provide some useful information if mechanisms existed to direct lay people to verifiable and credible sources.

Maxillary dentinogenic ghost cell tumour.

Dentinogenic ghost cell tumours are extremely rare, and pose significant diagnostic and therapeutic challenges as this case clearly demonstrates. An awareness of different clinical presentations and distinct histopathological features is important in establishing an early definitive diagnosis and instituting appropriate management. Furthermore, there is little precedent in the literature to guide management in such a case, and we therefore consider this report to be noteworthy and instructive in this respect.

Treatment algorithm for oral anticoagulant and antiplatelet therapy in epistaxis patients.

BACKGROUND AND OBJECTIVES: There is currently little published guidance on the management of anticoagulant and antiplatelet medication in patients admitted with epistaxis. The routine practice of withholding such medication in an attempt to control the epistaxis is common in the UK. However, this practice is not evidence-based, is often unnecessary, and can be associated with significant morbidity. This study introduces a treatment algorithm for oral anticoagulant and antiplatelet therapy in epistaxis patients, validated through a completed audit cycle. METHODS: One hundred patients admitted with epistaxis to the University Hospital Southampton NHS Foundation Trust were studied via a two-audit cycle covering the implementation of a new treatment algorithm formulated jointly by the otolaryngology and haematology departments. RESULTS: On admission, 58 per cent of patients were taking some form of anticoagulant or antiplatelet medication. The number of patients having such medication withheld decreased significantly between the two audits, for all drugs studied (i.e. aspirin, clopidogrel and warfarin). There was no significant increase in re-bleeding or re-admission rates between the audits. CONCLUSION: Implementation of this treatment algorithm would help standardise management for epistaxis patients taking anticoagulant or antiplatelet drugs, and should reduce morbidity associated with unnecessary routine discontinuation of such medication.

Rapidly progressing giant invasive prolactinoma.

OBJECTIVE: We report an extremely rare case of a giant invasive prolactinoma presenting as a nasopharyngeal tumour. METHOD: Case report and literature review regarding giant prolactinoma. RESULTS: Giant prolactinoma is a rare form of prolactinoma which accounts for 0.5-4.4 per cent of all pituitary tumours. It is more common in men and generally presents with symptoms of endocrine disturbance or neurological deficit. CONCLUSION: To our knowledge, this is the first report of giant prolactinoma presenting with symptoms of sinusitis and nasopharyngeal tumour.

Solitary extra-skeletal sinonasal metastasis from a primary skeletal Ewing's sarcoma.

INTRODUCTION: Ewing's sarcoma is a rare, malignant tumour predominantly affecting young adolescent males. We describe a unique case of an isolated extra-skeletal metastasis from a skeletal Ewing's sarcoma primary, arising in the right sinonasal cavity of a young man who presented with severe epistaxis and periorbital cellulitis. RESULTS: Histologically, the lesion comprised closely packed, slightly diffuse, atypical cells with round, hyperchromatic nuclei, scant cytoplasm and occasional mitotic figures, arranged in a sheet-like pattern. Immunohistochemical analysis showed positive staining only for cluster of differentiation 99 glycoprotein. Fluorescent in situ hybridisation identified the Ewing's sarcoma gene, confirming the diagnosis. MANAGEMENT: Complete surgical resection was achieved via a minimally invasive endoscopic transnasal approach; post-operative radiotherapy. Ten months post-operatively, there were no endoscopic or radiological signs of disease. CONCLUSION: Metastatic Ewing's sarcoma within the head and neck is incredibly rare and can pose significant diagnostic and therapeutic challenges. An awareness of different clinical presentations and distinct histopathological features is important to enable early diagnosis. This case illustrates one potential management strategy, and reinforces the evolving role of endoscopic transnasal approaches in managing sinonasal cavity and anterior skull base tumours.

Mechanisms and mediators of nasal symptoms in non-allergic rhinitis.

Non-allergic rhinitis may be a contributing factor in up to 60% of rhinitis patients and a sole contributor in a quarter. It is a highly heterogeneous condition with poorly understood pathophysiological mechanisms. Compelling evidence is emerging of a localized nasal mucosal allergic response in some non-allergic rhinitic subjects in the absence of systemic atopy. While the inflammatory disease pathway in non-allergic rhinitis may share some of the features of its allergic counterpart, overall the mechanisms remain unclear, and there are likely to be differences. In particular, symptoms of nasal congestion and rhinorrhoea tend to be more prominent and persistent in non-allergic rhinitic patients compared with allergic rhinitis. Our aim is to review the literature relating to mechanisms and mediators of nasal symptoms in non-allergic rhinitis. Better understanding of the underlying pathophysiological basis should enable the development of more accurate testing, and better targeted therapeutic options in the future.

Recurrent epistaxis after treatment with tadalafil (Cialis).

A 66-year-old male presented to our department with recurrent epistaxis. On examination it was not possible to identify the source of the bleeding, despite various measures. The bleeding stopped spontaneously each time and advice on nose bleeds was given to the patient. During a consultation the patient volunteered that the trigger for the epistaxis appeared to have been energetic sexual activity. To enhance his sexual performance he had taken Viagra; however, on stopping the Viagra and changing to the newer drug Cialis, the episodes of epistaxis continued. We document what we believe to be the first case of epistaxis caused by Cialis.

Recurrent extracranial sinonasal meningioma presenting 27 years after complete surgical eradication of right frontal meningioma.

A 79-year-old man presented to our department with nasal obstruction and postnasal drip. On examination he had unusual bilateral nasal polyps, which were histologically diagnosed as meningioma. Twenty-seven years earlier he had undergone successful removal of a right frontal meningioma. A CT scan performed 7 years after his primary surgery had shown complete excision with no evidence of recurrence. Extracranial meningiomas are rare tumours and are usually extensions from an intracranial mass lesion. We document what we believe to be the first case of an extracranial meningioma, presenting as nasal polyps, 27 years after successful surgical eradication of the primary lesion.

Can the Sino-nasal Outcome Test (SNOT-22) be used as a reliable outcome measure for successful septal surgery?

Septoplasty and submucous resection are common procedures in the UK. This study looks prospectively at 40 patients undergoing surgery at two hospitals. A pre- and postoperative assessment (3 months) was made using the Sino-nasal Outcome Test. This test was originally designed for rhinosinusitis but our study suggests that it is a useful tool in nasal septal surgery, in that it combines both nasal specific and general health questions, which can be analysed individually or together. Improvements in nasal obstruction (75%), facial pain (33%) and catarrh (10%) were noted.

Treatment of hereditary haemorrhagic telangiectasia by the pulsed dye laser.

Hereditary haemorrhagic telangiectasia (Osler-Weber-Rendu syndrome, Osler's disease) is an inherited abnormality of the vasculature characterized by abnormal subepithelial vessels. Treatment has included repeated intranasal cautery, intra-arterial embolization and arterial ligation. Historically, the operation of septodermoplasty and the use of systemic/topical oestrogens have been the most effective and lasting treatments, but over time the telangiectasias recur. There is increasing interest in the use of a variety of lasers for intranasal photocoagulation. A report of nine patients suffering from hereditary haemorrhagic telangiectasia who have undergone laser treatment with the Chromos pulsed dye laser is presented. This laser produces light energy at a wavelength of 585 nm and causes localized thermal damage to the blood vessel wall. Initially, no patient saw an improvement in their symptoms, but following an average of approximately three courses of treatment, all have reported a measurable reduction in the number of epistaxes suffered. Although no treatment completely resolves the epistaxis associated with this condition, we have found the pulsed dye laser to be effective at treating telangiectasias within the anterior nasal cavity.

Retropharyngeal abscess and acute torticollis.

Acute torticollis may result from an inflammatory process irritating the cervical muscles. In children there is often an association between acute torticollis and retropharyngeal cellulitis/abscess. Over six weeks, two children with acute torticollis presented to our Department. Both children were found to have retropharyngeal cellulitis/abscess. The problem of differentiating between the non-suppurative and the suppurative phases of the disease process is discussed.

Idiopathic tracheal stenoses.

The case histories are presented of three patients with circumferential subglottic stenoses who presented, over a six-month period, to a teaching hospital's Otolaryngology department. No recognisable cause for their subglottic stenoses was found. Traumatic, iatrogenic, infectious and specific inflammatory processes were excluded. The histopathological evidence suggested a chronic inflammatory process. All patients were treated by resecting the stenosis with a carbon dioxide laser. One patient required an emergency tracheostomy for airway obstruction. A review of the published literature on this rare condition is given.

Foreign body impaction arising in adulthood: a result of neonatal repair of tracheo-oesophageal fistula and oesophageal atresia.

Over a 3-month period, four patients presented to Salisbury District Hospital with symptoms of oesophageal foreign body impaction and dysphagia for solids. In their first few days of life all four patients had undergone successful operations for the repair of congenital oesophageal atresia with or without a tracheo-oesophageal fistula. Despite our efforts, the previous medical records were unavailable to ascertain the exact form of surgery each patient had received. All four patients had flexible oesophagogastroscopy by one of the authors (RAF). Three were found to have a food bolus obstructing the oesophagus, lodged above or within a ring stricture at the presumed level of their surgical repair and oesophageal anastomosis. The fourth patient had a ring stricture only; it was assumed that the food bolus had become disimpacted. All four patients had successful dilatations using thermoplastic oesophageal dilators. After the procedure all the patients were symptom free and remain so at varying lengths of follow-up. Case studies of these patients are presented below along with a review of the literature concerning the relatively rare presentation of dysphagia in adults who had previously undergone neonatal surgery for congenital oesophageal anomalies.

Adult floppy epiglottis: a simple surgical remedy.

Epiglottic prolapse during inspiration is an unusual cause of upper airway obstruction. We present a case of a previously fit, 73-year-old, male with upper airway obstruction secondary to a floppy epiglottis. We describe a simple method of treatment without the need for partial or total excision of the epiglottis or tracheostomy.
