Professor Pietro Tullio was a director at the Laboratory of Experimental Physiology in Bologna during the early twentieth century. His experimental studies resulted in the description of the Tullio phenomenon, which is characterised by sound-induced vertigo and/or eye movements.

The experimental studies behind his contribution to vestibular physiology are described within this paper, as are some of the further developments that have been made.

Application of one or several paper patches on the tympanic membrane can improve autophony and other symptoms in some patients with a patulous eustachian tube.

The charts of 21 patients treated for patulous eustachian tube syndrome between 2006 and 2011 were studied for subjective improvement of symptoms following the application of paper patches.

Paper patching of the tympanic membrane provided symptomatic relief in 76.2 per cent of patients; relief was permanent in 50 per cent of these patients.

Paper patching of the tympanic membrane is a simple and effective means of temporarily or permanently alleviating patulous eustachian tube syndrome symptoms. It is postulated that the patches decrease the admittance of low- to mid-frequency acoustic input at the tympanic membrane by increasing the stiffness of the tympanic membrane, thereby counteracting the middle-ear cushion effect caused by the open eustachian tube.

Low-dose clarithromycin has been recommended for the treatment of chronic rhinosinusitis without nasal polyps. However, it is uncertain whether a high dose of clarithromycin is more effective than a low dose.

Forty-three chronic rhinosinusitis patients were randomised to low-dose or high-dose clarithromycin groups, and clinical efficacy was evaluated. Pre- and post-treatment measures included: nasal symptom assessment, endoscopic inspection (Lund–Kennedy system), a quality of life questionnaire (the Sino-Nasal Outcome Test 20) and examination of cytokine levels (interleukin-5 and -8) in nasal secretions.

The high dose of clarithromycin was significantly better in terms of clinical efficacy than the low dose for the treatment of chronic rhinosinusitis (p < 0.025). Significant differences in nasal cytokine levels (interleukin-5 and -8) were also observed between the low-dose and high-dose groups after short-term clarithromycin treatment (p < 0.025).

Short-term, high-dose clarithromycin appears to be more effective for the treatment of chronic rhinosinusitis than low-dose clarithromycin.

This study investigated improvements in quality of life associated with eight weeks of montelukast and/or intranasal steroid treatment for moderate to severe allergic rhinitis.

A single-centre, prospective, randomised, double-blind, placebo-controlled study was carried out. Assessments were made using the Rhinoconjunctivitis Quality of Life Questionnaire and symptom scales.

A total of 128 patients (aged 13–51 years) were randomly assigned to one of two groups. In the montelukast group, patients were treated with montelukast tablets and fluticasone propionate nasal spray (n = 64). In the placebo group, treatment comprised a placebo and fluticasone propionate. The results showed significant improvements in symptom scores and quality of life scores for both groups after one month and two months of treatment, compared with baseline values; these improvements were significantly greater for the montelukast group compared with the placebo group. The mean number of loratadine tablets taken by each patient during the study period was only 0.73 for the montelukast group compared with 9 for the placebo group.

The combination of montelukast tablets and fluticasone propionate nasal spray improved symptom control and overall quality of life for moderate to severe allergic rhinitis patients.

To compare the efficacy of two modes of delivery of information for patients undergoing functional endoscopic sinus surgery: website and printed leaflet.

A two-centre, prospective, single-blinded, randomised, controlled trial was conducted, comparing mode of information delivery. Adult patients were randomly allocated to receive pre-operative information regarding functional endoscopic sinus surgery, either via a website or a printed leaflet. Primary outcomes, measured by questionnaire, were: readability, usability and recall of complications.

Fifty-eight patients were recruited. Fifty met the inclusion criteria, of which 40 were analysed in the study (20 patients per group), meeting the power criteria set. There were 18 male and 22 female patients, ranging in age from 21 to 76 years (mean, 47 years). Patients found both the printed leaflet and the website readable, and were satisfied with the usability of both modes. There were similar rates for recall of complications in both study arms.

Patient information on functional endoscopic sinus surgery can be provided either as a printed leaflet or a website, with similar rates for usability, readability and recall of complications. These findings could help tailor the provision of pre-operative information for patients undergoing functional endoscopic sinus surgery, based on patient preference.

A close relationship between upper and lower respiratory tract diseases has been reported. However, little is known about pulmonary function in patients with upper respiratory tract diseases.

Pulmonary function was measured in: 68 patients with chronic rhinosinusitis without nasal polyps, 135 patients with chronic rhinosinusitis with nasal polyps, 89 patients with allergic rhinitis and 100 normal control subjects. The relationships between pulmonary function and clinical parameters were assessed. These parameters included radiographic severity of chronic rhinosinusitis, serum total immunoglobulin E levels, concentrations of cytokines in nasal secretions and exhaled nitric oxide levels.

The pulmonary function of patients with chronic rhinosinusitis was significantly affected. The level of interleukin-5 in nasal secretions was significantly correlated with pulmonary function in patients with chronic rhinosinusitis.

The findings indicated latent obstructive lung function changes in chronic rhinosinusitis patients. The cytokines in nasal secretions might be related to obstructive lung function changes in chronic rhinosinusitis.

Many patients treated for head and neck cancer require nutritional support, which is often delivered using a gastrostomy tube. It is difficult to predict which patients will retain their gastrostomy tube in the long term. This study aimed to identify the factors which affect the duration of gastrostomy tube retention.

In this retrospective study, 151 consecutive patients from one centre were audited. All patients had a mucosal tumour of the head and neck, and underwent gastrostomy tube insertion between 2003 and 2007.

There were near-complete data sets for 132 patients. The gastrostomy tube was retained in survivors (n = 66) for a mean of 21.3 months and in non-survivors (n = 66) for 11.9 months. Univariate analysis showed that co-morbidity was the only factor which significantly increased duration of gastrostomy tube retention in survivors (p = 0.041).

Co-morbidity alone was associated with a significant increase in gastrostomy tube retention. It is suggested that co-morbidity be included as a variable in future relevant research. Co-morbidity should also be considered when counselling patients about their long-term function following cancer treatment. Gastrostomy tube retention is likely to be affected by many factors, with few single variables having importance independently.

To determine the patterns of lymph node metastases in oral tongue carcinomas, and examine the implications for elective and therapeutic neck dissection.

The study entailed a retrospective analysis of 67 patients with previously untreated oral tongue squamous cell carcinoma who had undergone simultaneous glossectomy and neck dissection.

Of the 40 clinically node-negative patients, 7 patients had metastatic lymph nodes on pathological examination. No occult metastasis was found at level IV. Of the 27 clinically node-positive patients, the incidence rate of level IV metastasis was 11.1 per cent (3 out of 27 patients). No ‘skip metastases’ were found at level IV. Level IV metastases were significantly related to clinically staged nodes categorised as over 2a (p = 0.03) and metastasis to level III (p = 0.01).

Routine inclusion of level IV in elective neck dissection is not necessary for clinically node-negative patients with oral tongue squamous cell carcinoma. Furthermore, extended supraomohyoid neck dissection with adjuvant radiotherapy can be sufficient in the treatment of selected patients with clinically node-positive necks.

To develop a practical, efficient and predictive algorithm to manage potential or actual post-operative hypocalcaemia after complete thyroidectomy, using a single post-operative parathyroid hormone assay.

This paper reports a prospective study of 59 patients who underwent total or completion thyroidectomy over a period of 24 months. Parathyroid hormone levels were checked post-operatively on the day of surgery, and all patients were evaluated for hypocalcaemia both clinically and biochemically with serial corrected calcium measurements.

No patient with an early post-operative parathyroid hormone level of 23 ng/l or more (i.e. approximately twice the lower limit of the normal range) developed hypocalcaemia. All the patients who initially had post-operative hypocalcaemia but had an early parathyroid hormone level of 8 ng/l or more (i.e. approximately two-thirds of the lower limit of the normal range) had complete resolution of their hypocalcaemia within three months.

Early post-operative parathyroid hormone measurement can reliably predict patients at risk of post-thyroidectomy hypocalcaemia, and predict those patients expected to recover from temporary hypocalcaemia. A suggested post-operative management algorithm is presented.

The prevalence of occult neck metastasis in patients undergoing salvage total laryngectomy remains unclear, and there is controversy regarding whether elective neck dissection should routinely be performed.

A retrospective case note review of 32 consecutive patients undergoing salvage total laryngectomy in a tertiary centre was performed, in order to correlate pre-operative radiological staging with histopathological staging.

The median patient age was 61 years (range, 43–84 years). With regard to lymph node metastasis, 28 patients were pre-operatively clinically staged (following primary radiotherapy or chemoradiotherapy) as node-negative, 1 patient was staged as N1, two patients as N2c and one patient as N3. Fifty-two elective and seven therapeutic neck dissections were performed. Pathological analysis up-staged two patients from clinically node-negative (following primary radiotherapy or chemoradiotherapy) to pathologically node-positive (post-surgery). No clinically node-positive patients were down-staged. More than half of the patients suffered a post-operative fistula.

Pre-operative neck staging had a negative predictive value of 96 per cent. Given the increased complications associated with neck dissection in the salvage setting, consideration should be given to conservative management of the neck in clinically node-negative patients (staged following primary radiotherapy or chemoradiotherapy).

To identify the prognostic significance of specific lymph node related characteristics for disease persistence and recurrence in patients with pre- or intra-operative evidence of neck metastases and no other risk factors.

Sixty-eight patients were identified; 50 per cent had persistent or recurrent disease. All underwent the same treatment strategy. There were no statistically significant differences in any of the patient- or tumour-related parameters when patients with and without persistence or recurrence were compared. Patients with recurrent or persistent disease had significantly larger (>3 cm) metastatic lymph nodes, but there were no differences regarding other lymph node related parameters (i.e. number, extracapsular extension, number of lymph nodes with extracapsular extension, and central vs lateral neck location). On multivariate analysis, however, none of the parameters were predictive of persistent or recurrent disease.

In papillary thyroid carcinoma patients with no other risk factors, pre- or intra-operative evidence of cervical metastases was associated with a very high rate of disease persistence or recurrence. Specific lymph node characteristics were not shown to have prognostic significance.

Non-healing ulcers can be caused by a number of conditions, including vascular disease, diabetes, malignancy and some infections. Drug-related ulcers are rare, and a high index of clinical suspicion is required for diagnosis, in parallel with exclusion of more sinister underlying causes.

We present a patient with a complex medical background, who had a 10-week history of a non-healing ulcer on his nasal bridge. Inflammatory, autoimmune and malignant causes for the ulcer were excluded by histopathology.

Nicorandil was deemed to be the most likely cause for the patient's ulcer. Nicorandil is an anti-anginal medication known to cause oral ulceration and skin lesions in the perianal and peristomal regions and around surgical wounds. However, there are no previously reported cases of facial ulcers. The ulcer required surgical debridement and healed completely within six months, following discontinuation of nicorandil. This case highlights the importance of having a high index of clinical suspicion regarding non-healing ulcers, and of considering drugs as an aetiological factor, especially in patients with a complex medical background who are taking numerous medications.

To report a case of misdiagnosis of an impacted oesophageal button battery in a child, and to describe the associated risk factors for impaction and the management of such cases.

An 18-month-old, otherwise fit and well child with stridulous respiration was initially treated for croup. Medical treatment over the course of three months failed, and appropriate imaging subsequently demonstrated an impacted button battery in the upper oesophagus. This was promptly removed. There were no signs of damage on direct visualisation, or on a follow-up contrast swallow image.

This case highlights the difficulty of diagnosing oesophageal foreign bodies. We also discuss the characteristics of button batteries which confer a greater risk of impaction, and the associated sequelae and complications.

Liposarcomas of the larynx and its sub-sites are rare. Within this group of tumours, well-differentiated liposarcomas of the epiglottis have been only sporadically reported. In view of its infrequent presentation, difficulty still exists over the diagnosis of this pathological entity, together with uncertainty over its exact accepted management.

We present the case of a well-differentiated liposarcoma of the epiglottis, and we review the associated English-language literature.

The reported patient underwent multiple attempts at surgical treatment prior to establishment of a firm diagnosis. In light of the diagnosis and other mitigating factors, a conservative approach was adopted.

A high index of clinical suspicion and detailed histological analysis are required when encountering a recurrent soft tissue lesion of the larynx. In the presented case, a multidisciplinary approach and conservative management plan were adopted, based on a holistic management approach and a review of the published literature.

Acute respiratory decompensation can occur on a background of slowly progressive airway compromise, for example in laryngeal squamous cell cancer. Surgeons in ENT, together with anaesthetists, are often asked to evaluate airway risk and as yet there is no widely adopted standardised approach.

This paper reports the case of an 82-year-old male, who presented with acute airway compromise due to both endolaryngeal obstruction from a squamous cell cancer and extralaryngeal compression from massive subcutaneous emphysema.

Primary total laryngectomy was performed, but the patient declined adjuvant radiotherapy. He died a year later from a heart attack without evidence of recurrence.

To the best of our knowledge, this is the first case report of acute airway compromise from extralaryngeal subcutaneous emphysema secondary to laryngeal cancer. Options for acute airway management are discussed.

Complementary and alternative medicine usage, though rising, remains largely devoid of a sound scientific basis; however, there is increasing evidence to support its use in cancer therapy.

To present the case of a patient with laryngeal carcinoma who made a full recovery following mistletoe therapy, despite failing to respond to chemoradiotherapy and salvage laryngectomy.

Case report with relevant literature review.

The patient developed extensive, unresectable stomal recurrence, and it was deemed appropriate to supply palliative care only. Following treatment with mistletoe extract injections after palliative radiotherapy, he recovered fully and was eventually discharged from care.

The benefit of mistletoe in laryngeal cancer treatment requires further investigation, and might be considered in selected patients, as an adjunct or when other conventional therapies have failed.
