RESUMO

OBJECTIVE: Bacterial infection is a common finding in acute sialadenitis and may play a role in the chronicity of the condition. This study investigated if bacterial biofilm is present in submandibular chronic obstructive sialadenitis. METHODS: A descriptive case-control study was conducted that compared 10 histological sections of submandibular glands with chronic obstructive sialadenitis, to 10 histological sections of the healthy part of submandibular glands with pleomorphic adenoma. Fluorescence in situ hybridisation and confocal laser scanning microscopy visualised evidence of bacterial biofilm. RESULTS: In the chronic obstructive sialadenitis group, 5 out of 10 histological sections showed morphological evidence of bacterial biofilm. In the control group, there was no sign of bacterial biofilm formation. CONCLUSION: Morphological evidence of bacterial biofilm was found in the submandibular gland sections from patients with chronic sialadenitis and suggests a role in the chronicity of submandibular chronic obstructive sialadenitis.

RESUMO

The demographics of parotid neoplasms in different populations have been reported by various centres. In this investigation, we reviewed retrospectively all the in-patient and out-patient charts and records of 108 patients who were diagnosed with parotid neoplasms and received parotidectomies in our department from 1 January 1993 to 15 April 2000. Patient age, gender, tumour pathology, fine-needle aspiration cytology results, and the intraparotid anatomy of the facial nerve were noted. We showed that despite the difference between our Taiwanese and previously studied patient populations, both populations had a similar distribution, diagnosis and treatment of parotid neoplasms, although the incidence of parotid tuberculosis was higher in our patient group. In addition, the facial nerve anatomy within the parotid gland had three main branching patterns in the upper and lower division.
