Porphyromonas asaccharolytica liver abscess

The black pigmented Gram-negative anaerobes, Porphyromonas species, have been isolated from clinical specimens in cases of central nervous system, dental-oral, pleuropulmonary and genitourinary infections and bacteremia. Herein, we report an unusual case of liver abscess caused by Porphyromonas asaccharolytica that has not been previously reported.     

Orbital abscess following blepharoplasty

Orbital abscess following blepharoplasty is surprisingly rare. The diagnosis may not be obvious from the physical signs alone. Ultrasonography is a helpful diagnostic tool in such problems. The abscess cavity can be visualized. A case of orbital abscess is presented.     

Anaerobic axillary abscess.

Fifty-two patients with axillary abscesses were seen during two years. Staphylococcus aureus was isolated from 34, anaerobic bacteria from 12, and skin flora from five; in one case the pus was sterile. Seven patients with hidradenitis suppurativa had recurrent infection with abscess formation, which was bilateral in three. Anaerobes were isolated in five of these cases and skin flora alone in two. Anaerobes are secondary invaders in this condition, and histological examination shows that the primary abnormality is obstruction of pilosebaceous follicles and apocrine glands, associated with keratin plugging of the follicles. Chemotherapy offers little hope of cure, although metronidazole removes the offensive smell of the discharge. Radical surgery is usually indicated.
