Neuroendocrine carcinoma arising from the septum. A very rare nasal tumour.

The case is presented of a 73-year-old male with a history of right-sided nasal obstruction, hyponasal speech and three episodes of recurrent epistaxis. On examination, there was a tumour in the right nasal cavity. Computed tomography showed a mass in the right nasal cavity extending to the right maxillary sinus, ethmoidal cells and right sphenoid sinus. The patient underwent a functional endoscopic removal of the tumour. Biopsy revealed a small cell neuroendocrine carcinoma. This is an extremely rare tumour of the nasal cavity and sinuses. Because of the aggressive behaviour of this tumour, he was also treated with combined chemotherapy and radiation. Ten months later, he remains free of disease.

Adenoidectomy plus tympanostomy tube insertion versus adenoidectomy plus myringotomy in children with obstructive sleep apnoea syndrome.

OBJECTIVE: To determine whether tympanostomy tube insertion has benefit, compared with simple myringotomy, in children with otitis media with effusion who receive concurrent adenoidectomy as treatment for obstructive sleep apnoea syndrome caused by adenoid hypertrophy. METHODS: Fifty-two children older than three years with obstructive sleep apnoea syndrome were randomly assigned to receive either adenoidectomy plus tympanostomy tube insertion (group one, n = 25) or adenoidectomy plus myringotomy (group two, n = 27). Pre- and post-operative health-related quality of life was assessed using the otitis media-6 (OM-6) tool, and audiological outcomes were recorded six and 12 months post-operatively. RESULTS: Group one showed better quality of life scores six months post-operatively (score difference -0.38, confidence interval -0.65 to -0.10) but not 12 months post-operatively (score difference -0.23, confidence interval -0.76 to 0.11), compared with pre-operative values. Audiological outcomes did not differ significantly at either time point, compared with pre-operative values. CONCLUSION: Tympanostomy tube insertion confers a short term benefit, compared with simple myringotomy, in children older than three years with otitis media with effusion who receive concurrent adenoidectomy as treatment for obstructive sleep apnoea syndrome. Further studies are necessary to identify which of these children will receive long-lasting benefit from tympanostomy tube insertion.

Clinical outcomes of sinonasal inverted papilloma surgery. A retrospective study of 67 cases.

BACKGROUND: Endoscopic sinus surgery has become popular for the management of sinonasal inverted papillomas (IP). OBJECTIVE: The purpose of this report is to review our 13 years of experience in managing IPs. METHODS: Retrospective chart study. Sixty-seven patients with sinonasal IPs were treated in our department from 1991 to 2004. Seventeen were managed using an endonasal non-endoscopic approach, 39 endoscopically, 8 through external techniques, and the remaining 3 using a combined approach. RESULTS: After 1994, as we gained experience using endoscopic sinus surgery, most cases were treated endoscopically. In only 3 cases, where the tumour attachment site was in the lateral / anterior wall of the maxillary sinus and in the lateral wall of the frontal sinus, could the lesions not be accessed by extended endoscopic techniques, and an appropriate combination with external methods was required. The mean follow up period was 91 (range, 36-146) months. The recurrence rate was 59% using an endonasal non-endoscopic approach, 12.5% using an external incision, and 12.8% using endoscopic techniques. Average time to recurrence was 15 months. CONCLUSION: Our findings suggest that endoscopic sinus surgery for sinonasal IP is a viable approach, with a low rate of recurrence and minor morbidity. Complete tumour resection at the site of attachment, including a surrounding rim of normal mucosa and drilling the underlying bone, is the key to successful treatment when it is combined with the preservation of healthy tissue. Non-endoscopic endonasal surgery is no longer a treatment option because the recurrence rate is too high.

Quality of life in children with chronic suppurative otitis media with or without cholesteatoma.

OBJECTIVE: To validate a disease-specific health related quality of life (HRQOL) instrument for children with chronic suppurative otitis media with or without cholesteatoma. METHODS: Caregivers of 45 children with chronic suppurative otitis media, who were offered an operation (tympanoplasty or radical mastoidectomy) in a tertiary children's hospital, were administered a 5-item quality of life survey (COM-5) The COM-5, which is a modified version of OM-6, was administered four times: few weeks and few days before operation and six months and one year postoperatively. Psychometric characteristics and more specifically test-retest reliability, internal consistency, construct validity, and responsiveness to clinical change of the COM-5 score were the main outcome measures. RESULTS: Median COM-5 score was 2.6 (1- to 7-point scale) with higher scores indicating poorer quality of life. Test-retest reliability was good (interclass correlation coefficient=0.73) Construct validity was demonstrated by significant correlations between COM-5 score and global ear-related quality of life (R=-0.485), between physical suffering and ear-related physician visits (R=0.41) and between caregiver concerns vs ear-related physician visits (R=0.44). The mean change in COM-5 score after successful tympanoplasty was 1.1 and correlated well with the change of global ear-related quality of life rating (R=-0.545) as well as with the degree of clinical change reported by the caregiver (R=0.494). The mean standardized response was 1.3 after tympanoplasty indicating the instrument's large responsiveness to clinical change after this procedure, but only 0.7 after radical mastoidectomy. CONCLUSIONS: The COM-5 is a valid, reliable and responsive instrument. Apart from its satisfactory psychometric characteristics, it can be easily administered in caregivers of children who require a tympanoplasty due to chronic suppurative otitis media.

Expression of substance P, vasoactive intestinal peptide and heat shock protein 70 in nasal mucosal smears of patients with allergic rhinitis: investigation using a liquid-based method.

OBJECTIVE: The aim of this study was to investigate expression of the neuropeptides substance P, vasoactive intestinal peptide and heat shock protein 70 in the nasal mucosa cells of patients with seasonal allergic rhinitis, in order to obtain more information on the pathophysiological and immunological role of these markers in allergic rhinitis. MATERIAL AND METHODS: Nasal epithelium specimens obtained from 42 patients with allergic rhinitis were studied, using Shandon's Papspin liquid-based cytology method. Smears were immunostained with antibodies against substance P, vasoactive intestinal peptide and heat shock protein 70, and the results were correlated with the clinical features of seasonal allergic rhinitis. RESULTS: A positive reaction for substance P, vasoactive intestinal peptide and heat shock protein 70 was observed in 73.8, 66.7 and 69.0 per cent of the allergic rhinitis mucosal smears, respectively. The Pearson chi-square test showed that 40.5 per cent of the immunostained smears had a positive reaction for one or two of the markers studied (i.e. substance P, vasoactive intestinal peptide or heat shock protein 70), and that 47.6 per cent of the smears had a positive reaction for all the markers (p < 0.0001). CONCLUSIONS: We found a high level of expression of substance P and vasoactive intestinal peptide in the nasal mucosa smears of patients suffering from allergic rhinitis. This indicates a role for these neuropeptides in the neuroregulation of immunity and hypersensivity in this disease. Furthermore, expression of heat shock protein 70 may contribute to the development of allergic rhinitis.

Long-term effects of chemotherapy for acute lymphoblastic leukemia on the medial olivocochlear bundle: effects of different cumulative doses of gentamicin.

OBJECTIVE: The treatment of acute lymphoblastic leukemia (ALL) often combines a neurotoxic chemotherapeutic protocol such as Berlin-Frankfurt-Munster-95 (BFM-95) with gentamicin, an antibiotic known to have an early and quickly reversed impact on olivocochlear reflex in animal studies. This study investigates whether this combination has any long-term side effects on the medial olivocochlear bundle (MOCB). METHODS: In all 47 children of the study suppression of distortion product otoacoustic emissions (DPOAEs) by contralateral application of white noise (WN) was used to assess the function of the MOCB. The population was divided into three groups depending on the time interval between the end of therapy and examination. The group examined shortly after chemotherapy included 12 children who had received low gentamicin doses (less than 13 days). The group evaluated 2 years after therapy involved another 12 children who had required medium gentamicin doses (more than 13, less than 23 days). The group examined 3 years after therapy included a subgroup of 12 children to whom low gentamicin doses were infused and another 11 children with high gentamicin doses (more than 23 days). RESULTS: Three years after therapy the olivocochlear reflex was efficiently produced in both subgroups of low and high gentamicin doses. Two years after therapy, contralateral WN induced increase of DPOAEs at 4 of the 12 examined frequencies. Shortly after therapy, WN increased, instead of suppressing, DPOAEs at five frequencies. CONCLUSION: This abnormal result of contralateral noise application perceived as impaired cochlear efferent innervation may indicate that ALL-BFM-95 exerts a toxic effect on the MOCB, which is slowly reversed within the first 3 years after chemotherapy and does not seem to be affected in the long term by different cumulative doses of gentamicin.

Surgical correction of pinna malformations.

BACKGROUND: Auricle reconstruction is a surgical procedure described in the medical literature as early as 600 BC. The aim of the present paper is to review these attempts and their results. METHODS: Literature search and medical history books were used as scientific sources. RESULTS: More than 40 different cartilagenous, osseous or other alloplastic frame materials (autogenous tibial bone, iliac bone, mastoid bone, maternal auricular cartilage, autogenous nasoseptal cartilage, allogenous meniscus, autogenous meniscus and many more) have been used since 1891. From approximately 40 reconstruction procedures that had been proposed, only eight were still in use in the 1980s. The reason for abandoning the majority of these surgical techniques was the unacceptable aesthetic result. However, at the end of the 20th Century two new techniques were introduced. These techniques were designed by Satoru Nagata and Burt Brent. Both techniques provide cosmetic and functional results that are acceptable both to the patient and to the surgeon. CONCLUSIONS: Although the outcome of surgical auricle reconstruction was in general disappointing through the centuries, at the end of the 20th Century new surgical methods were established and at the present time auricle reconstruction can be attempted with acceptable results.

Prospective study of a panel of tumor markers as prognostic factors in patients with squamous cell carcinoma of head and neck.

OBJECTIVE: The identification of a reliable circulating tumor marker in squamous cell carcinoma of the head and neck (SCCHN) could assist in diagnosis and monitoring response to therapy. AIM: The aim of this study was to investigate the effectiveness of the serum tumor markers CYFRA 21-1, TPA-M, SCCA, and CEA. STUDY DESIGN: Serum levels of CYFRA 21-1, TPA-M, SCCA, and CEA were measured in 136 patients with a histologically proven SCCHN before and after treatment and in 125 healthy subjects, as controls. We evaluated the sensitivity and specificity of these tumor markers and to correlate their levels with tumor staging, grading, or performance status. RESULTS: The study showed that none of the above markers presented satisfactory specificity and sensitivity in early diagnosis. In comparison with the other markers, TPA-M was the most effective of all markers and indicated a positive correlation with the grade of differentiation and nodal status. A remarkable correlation between high levels of TPA-M and CYFRA 21-1 in advanced stages (III, IV) of cancer has been shown. CONCLUSIONS: All the tumor markers that were studied have significant limitations in the early diagnosis of cancer, but TPA-M and CYFRA 21-1 may have a role in monitoring the success of therapy and follow up of patients with SCCHN.

Silent sinus syndrome, a case presentation.

"Silent Sinus Syndrome" is a quite rare condition of otherwise asymptomatic maxillary sinusitis that presents with enophthalmos. Despite the fact that the "Silent Sinus Syndrome" presents with enophthalmos, these patients are finally treated by the otorhinolaryngologist, who should be familiar with this condition, in order to facilitate prompt diagnosis and treatment. We present the case of a 33 year old man with enophthalmos and no other associated symptom that was caused by chronic rhinosinusitis. Functional endoscopic sinus surgery was the treatment of choice. No reconstruction of the orbital floor was performed. One year follow up, following surgical treatment revealed an excellent result.

Pleomorphic adenoma of the nose.

Pleomorphic adenoma is the most frequent tumor of the major salivary glands. It is rarely located in the lacrymal glands and is unusual in the nasal cavity. A rare case of a pleomorphic adenoma of the nose is presented along with a review of the literature. The use of nasal endoscopy in removing tumors of the nose and paranasal sinuses is discussed.

Isolated inverted papilloma of the sphenoid sinus.

Inverted papilloma is a rare benign sinonasal tumour, characterized by a potentially invasive nature. The lateral nasal wall represents the most common site of origin, whereas paranasal sinuses are quite frequently found to be involved by extension. In contrast, primary sinus inverted papillomas have rarely been reported. The present study describes an extremely rare case of inverted papilloma, isolated to the left sphenoid sinus, that was treated by a transnasal endoscopic procedure. The therapeutic approach chosen is discussed and the results of a two-year follow-up are also presented.

Cervical versus thoracic epidural morphine for the treatment of head and neck cancer pain.

We studied 29 patients in the final stage of head or neck cancer who were suffering pain that was not relieved by oral morphine. Cervical or thoracic epidural morphine was administered to relieve the pain. The quality of analgesia was equally good for both techniques. However, cervical epidural administration appeared to be superior, because much smaller doses of morphine were required in order to induce more rapid and longer analgesia.

Isolated sphenoid sinus aspergillomas.

Fungi are more often than previously believed to be the causative organisms of paranasal sinusitis. Aspergillus, a fungus belonging to the Ascomycetes class, accounts for the majority of these infections, which affect not only debilitated patients but healthy people as well. There are two distinct clinical forms of Aspergillus sinusitis, invasive and non-invasive, and each of them is further divided in two subtypes. Isolated aspergillosis of the sphenoid sinus is a rare disease, which is usually misdiagnosed for a long time because of its varying symptomatology. In the present study, four cases of isolated sphenoid Aspergillus disease are described and the recent literature is reviewed. Physicians should be aware of this rare clinical entity, as in many cases early diagnosis and appropriate treatment provide the key to achieve favourable outcomes.
