A comparison of computerized tomographic staging systems in chronic sinusitis.

A number of different systems exist for staging computerized tomography (CT) scans in rhinosinusitis. The aim of this study was to determine which of four selected staging systems, currently in common use facilitated the highest level of agreement. The systems studied were those by Jorgensen (1991), May and Levine (1991), Lund and Mackay (1993) and Newman (1994). Ten observers independently assessed 10 representative films. In our assessment, the Lund and Mackay system facilitated the highest level of both inter-observer and intra-observer agreement of the four systems tested. We recommend it be adopted as the standard method of measuring the extent of disease, as depicted by CT scanning for chronic. rhinosinusitis.

Treatment of head and neck cancer with photodynamic therapy: results after one year.

Photodynamic therapy (PDT) is a new and promising treatment modality for the treatment of malignant disease. This paper reports the preliminary experience of our group in the use of this therapy for the treatment of tumours arising in the head and neck. The majority of treatments in these cases have used a second generation systemic photosensitizer, meta-tetrahydroxyphenylchlorin (m-THPC). Two other cases were treated with either Photofrin 2 (a first generation systemic sensitizer) or with the topical photosensitizer, delta-aminolaevulinic acid (delta-ALA). The initial results have been encouraging with good clinical responses evident in patients presenting with a variety of differing tumour types. We feel there is now sufficient evident of the efficacy of this treatment to warrant a multicentre prospective study into the treatment of early head and neck cancer with PDT.

Myxoma of the larynx: a case report and a review of the literature.

Laryngeal myxomas are rare benign mesenchymal tumours in contrast to myxomatous degeneration in laryngeal polyps which occurs frequently. A correct diagnosis of myxoma is usually not difficult to reach if the possibility of myxomatous degeneration in laryngeal polyps is excluded and strict pathological criteria are adhered to. We report a myxoma arising from the left vocal fold in a 64-year-old male who presented with a four-year history of intermittent dysphonia. Although excision was microscopically incomplete, there is no evidence of recurrence macroscopically 18 months later and the patient remains asymptomatic.

Tympanic membrane injury in welders: is prevention neglected?

Injury to the ear in welders is a recognized but poorly documented entity. Five cases are described to demonstrate a spectrum of severity of injury, ranging from minor burns to tympanic membrane perforation requiring myringoplasty. Welders are most at risk when working overhead, in cramped conditions or adjacent to other welders. Conventional safety helmets offer inadequate protection to the ears and it is recommended that insert ear plugs should be offered to all workers at risk, in addition to safer working practices. An increased awareness of these risks among occupational physicians, welders and employers is required before these recommendations can realistically be implemented.
