- Actinomycosis of the middle ear. [JOURNAL ARTICLE]
- J Laryngol Otol 2013 Jun 13.:1-4.
Objective:To present the first case of middle-ear actinomycosis in the UK in the last 60 years. The diagnosis and management of actinomycosis of the middle ear is also presented, as well as a review of the recent literature. Case report: This paper reports the case of a nine-year-old girl who presented with recurrent otorrhoea caused by actinomycosis. Mastoid exploration with clearance of the infected tissue, in conjunction with six months amoxicillin, resulted in long-term disease remission. Histology revealed Gram-positive, silver avid (on Grocott staining) and diastase-resistant periodic acid-Schiff negative staining of colonies; this profile was in keeping with the characteristic 'sulphur granules' of actinomycosis.
Conclusion:Actinomycosis of the middle ear and mastoid is rare, with less than 45 cases presented in the worldwide literature. This case confirms that the disease should be treated with full surgical clearance and long-term antibiotics.
- Physical characteristics of commercial and home-made nasal lavage solutions. [JOURNAL ARTICLE]
- J Laryngol Otol 2013 Jun 11.:1-4.
Introduction: Nasal saline lavage forms a cornerstone of chronic rhinosinusitis management. A number of saline lavage recipes and products are currently available but little is known of their relative physical characteristics.
Aims:To determine the osmolarity and pH of nasal lavage solutions, both commercial preparations and home-made recipes, and to determine the reproducibility of saline solution preparation.
Methods:Five home-made recipes and two commercial products were prepared in triplicate and analysed. Eight consecutive clinic patients prepared a commercial product and 11 prepared a home-made recipe, and the osmolarity and pH were measured.
Results:The osmolarity of the solutions varied widely, from 140 to 788 mmol/l and the pH varied from 7.88 to 8.50. The commercial and home-made solutions had similar reproducibility when prepared by patients.
Conclusion:Some recipes were markedly hypo-osmolar and some were hyper-osmolar. All were slightly alkaline. The home-made recipes had similar physical characteristics and reproducibility to commercial preparations.
- Giant cell reparative granuloma of the temporal bone successfully resected with preservation of hearing. [JOURNAL ARTICLE]
- J Laryngol Otol 2013 Jun 11.:1-5.
Objective:To describe a case of giant cell reparative granuloma of the temporal bone which extended into the middle-ear cavity, and which was successfully treated surgically via a transmastoid approach, with hearing preservation. Case: A 37-year-old man presented with a one-year history of right-sided hearing loss, complicated by a three-month history of otalgia and a sensation of aural fullness. Computed tomography and magnetic resonance imaging demonstrated an osteolytic tumour lesion in the right temporal bone. The diagnosis was confirmed by biopsy from the mastoid lesion. Investigation and intervention: Pure-tone audiometry, computed tomography and magnetic resonance imaging were conducted, followed by total resection. Result: The giant cell reparative granuloma of the temporal bone was completely resected, with preservation of hearing.
Conclusion:Although this patient's giant cell reparative granuloma of the temporal bone extended into the middle-ear cavity, total resection was achieved, with preservation of hearing. To the best of our knowledge, hearing preservation following resection of giant cell reparative granuloma of the temporal bone has not previously been reported.
- Hyperbaric oxygen therapy for sudden sensorineural hearing loss in large vestibular aqueduct syndrome. [JOURNAL ARTICLE]
- J Laryngol Otol 2013 Jun 6.:1-5.
Introduction: We report the first use in Australia of hyperbaric oxygen therapy for sudden hearing loss following head trauma in a child with large vestibular aqueduct syndrome. Case report: A 12-year-old boy with large vestibular aqueduct syndrome presented with significant hearing loss following head trauma. He was treated with steroids and hyperbaric oxygen therapy, with good improvement of hearing thresholds on audiography. This case represents the first reported use of hyperbaric oxygen therapy for this indication in Australia, following a few previous reports of patients in Japan. We review the literature on management of acute sensorineural hearing loss in large vestibular aqueduct syndrome. The reported case demonstrates a potentially beneficial therapy for a rare condition that usually results in an inevitable decline in hearing.
Conclusion:Hyperbaric oxygen therapy can be tolerated well by children, and may represent a potential treatment for sudden sensorineural hearing loss in patients with large vestibular aqueduct syndrome.
- Characteristics and prognostic factors for head and neck non-Hodgkin's lymphoma in Chinese patients. [JOURNAL ARTICLE]
- J Laryngol Otol 2013 Jun 6.:1-6.
Background and objectives: The head and neck region is the second most frequent anatomical site of extranodal lymphomas. These tumours affect many individuals worldwide, justifying epidemiological studies in different countries. This study evaluated the characteristics, treatments and prognostic factors for non-Hodgkin's lymphoma of the head and neck in Chinese patients. Method: The clinical manifestations, clinicopathological characteristics, multidisciplinary treatment and prognostic factors for 102 patients with extranodal non-Hodgkin's lymphoma of the head and neck were analysed retrospectively. Result: The tonsil was the most commonly involved primary site, followed by the nasal cavity. The most common histological subtype was diffuse large B-cell lymphoma, followed by natural killer T-cell lymphoma. Patients receiving a combination of rituximab and chemotherapy did better than those receiving chemotherapy alone. Prognosis was significantly associated with both International Prognostic Index and histological subtype; the former was especially strongly associated with poor survival.
