She possessed nine pet rats, and denied that she had been bitten. blood culture was positive for streptobacillus moniliformis, which can cause rat-bite fever. The patient fully recovered after treatment with clarithromycin. ( info) |
2/3. 'Papillomatization' and 'malignant transformation' of an abscess cavity in a 25-year old man with recurrent respiratory papillomatosis who may have had lemierre syndrome. We report here an unusual case of a 25-year old male with juvenile onset recurrent respiratory papillomatosis who developed an infestation of papillomata 'papillomatization' of an old abscess cavity that, when removed, was coincidently found to contain a 2 cm well differentiated squamous cell carcinoma. The abscess cavity had been caused by a previous Fusobaterium necrophorum infection that probably developed as a result of septic emboli from his internal jugular veins. This once common but now rare occurrence was first reported by Dr Lemierre in 1936 (lemierre syndrome). ( info) |
3/3. leptotrichia buccalis: a rare cause of bacteraemia in non-neutropenic patients. The anaerobic bacterium, leptotrichia buccalis (Lb), belongs to the normal oral flora of humans and is seldom found in clinically significant specimens. However, on rare occasions, Lb has been isolated from blood cultures from patients with lesions of the oral mucosa, in particular from patients with neutropenia. Over a period of 6 months, Lb was isolated from blood cultures in our laboratory from 2 immunocompetent patients. The identification characteristics of Lb are described including the typical morphology at microscopy. Furthermore, we review the bacteraemic cases reported so far together with present knowledge of the pathogenicity and epidemiology of Lb. ( info) |
