A review of 107 cases of acute maxillofacial infections managed at the Royal Melbourne Hospital was undertaken, and details of the presentations, demography, management, and outcomes of these patients are presented. The results indicated that many of the patients had sought treatment from dentists in general practice, and that a significant proportion had received sub-optimal management prior to referral. Thus a review of the principles of management and guidelines for the referral of patients with maxillofacial infections is also presented.

Nineteen cases of Pseudomonas pickettii bacteraemia and one case of Pseudomonas cepacia bacteraemia were identified in an Australia‐wide outbreak of nosocomial sepsis associated with contaminated water for injection. The contamination was limited to one batch of commercially produced water for injection. Four different organisms were identified (three biotypes of P. pickettii and one of P. cepacia). However, P. pickettii biotype 1 appeared to be relatively more virulent than the other biotypes as it was the only identified organism in blood cultures in nearly all cases of sepsis. The ampoules of “sterile” water were each contaminated with approximately 103organisms per millilitre. The lack of an Australian central reporting system for bacteraemia delayed the recognition of this outbreak.

A 63-yr-old woman with systemic lupus erythematosus (SLE) diagnosed 12 mo previously and treated with prednisolone and cyclophosphamide presented with recent fever and dyspnoea. The etiology of a 3 cm diameter centrally cystic coin lesion in the lower lobe of the left lung was obscure. Blood cultures and sputum examination had been non-contributory, and the diagnosis of Nocardia asteroides infection was initially made by cytologic examination of material obtained by lung fine-needle aspiration (FNA). It is notoriously difficult to detect this organism by conventional sputum examination or with histologic sections, and it has rarely been detected by lung FNA. If this organism is demonstrated, appropriate microbiologic cultures for confirmation and susceptibility testing should be instituted. Long-term antimicrobial therapy is needed. In this case, complete resolution of the lung lesion followed 5 mo of therapy.
