RESUMO

OBJECTIVE: To establish an olfactory test in the Hong Kong Chinese population. STUDY DESIGN: Prospective analysis of the results of a combined olfactory test (COT) for patients with olfactory dysfunction and for normal subjects attending a secondary and tertiary ear, nose and throat centre. METHOD: Our COT was based on and modified from the Connecticut Chemosensory Research Centre test. It consisted of an odour identification test involving nine substances and a threshold test using a series of threefold dilutions of 1-butanol. From September 1998 to June 2002, 188 Hong Kong Chinese patients with olfactory dysfunction and subjects with normal olfaction were prospectively recruited. The subjects were categorized into normal, hyposmic and anosmic groups. The olfactory function of the main group of subjects (n = 153) was assessed with the COT by a blinded observer and also quantified with a visual analogue scale; the results were analysed to validate the discriminative ability of the COT. Another subgroup of subjects (n = 35) was tested with the COT twice with a two-week interval to evaluate test-retest reliability. RESULTS: There were 42 normal, 68 hyposmic and 43 anosmic subjects within the main group (total n = 153). The identification scores, threshold scores and combined olfactory scores were statistically significantly different between the anosmic, hyposmic and normal groups of subjects (p < 0.001). The combined olfactory score correlated with the visual analogue score and the correlation coefficient was 0.56 (p < 0.01). The mean time spent on each COT was 8.6 minutes (standard deviation = 3.4 minutes). The test-retest reliability of the COT was satisfactory, with a one-way model intraclass correlation coefficient of 0.87 (n = 35). CONCLUSION: The satisfactory discriminative ability and test-retest reliability of the COT have been demonstrated in this study. The COT is a feasible method for assessing sense of smell in the Hong Kong Chinese population.

RESUMO

Over a 6.5-year period, 5,848 patients who had ingested a foreign body were admitted to the ENT unit at the Prince of Wales Hospital in Hong Kong. Potentially serious complications developed in 12 patients (0.21%). Eight patients had an esophageal perforation; three had clinical evidence that their injury had been caused by the foreign body itself and five were deemed to have been injured iatrogenically during esophagoscopy. One of the latter group eventually developed an abscess. Four patients originally presented with an abscess. Three of these patients and the patient who later developed an abscess were treated with neck exploration and surgical drainage. One of the patients who initially presented with an abscess refused surgical treatment and was treated conservatively. Conservative treatment was also initiated for all patients who had a perforation. Patients on the conservative regimen were administered intravenous broad-spectrum antibiotics and were not permitted to take any food or liquids by mouth; they received their nutrition via either enteral feeding or total parenteral nutrition. Conservative treatment was successful in all seven patients with a perforation and no abscess and in the one patient with an abscess who refused surgery. Moreover, all four patients who underwent surgical treatment recovered. Our experience demonstrates that esophageal perforation related to an ingested foreign body can be safely treated by conservative means if the diagnosis is made before significant contamination occurs. Conversely, abscesses (cervical or mediastinal) related to an ingested foreign body should be explored and surgically drained.
