Adverse reactions to injectable aesthetic microimplants.

New inert materials such as polymerized silicones, Bioplastique, Artecoll, and Dermalive are now being used as injectable aesthetic microimplants. These substances are better than the old ones because they tend not to migrate and do not usually produce much of a host immune response. Adverse reactions after injection of these materials are rare, although there are a few reported cases as a result of bad technique or anomalous granulomatous reactions. We report on four patients with unsightly results after cosmetic microimplants, including one of Artecoll, one of Dermalive (to the best of our knowledge, the latter is the first such case reported), and two of silicone. This report describes the histopathologic features of cutaneous reactions to these injectable aesthetic materials.

Lipoatrophia semicircularis--a traumatic panniculitis: report of seven cases and review of the literature.

Lipoatrophia semicircularis is an apparently rare condition, which presents as semicircular band-like atrophy of the subcutaneous fatty tissue and involving half the circumference of the anterolateral aspects of the thighs. Repeated external microtraumatism seems to be the most plausible explanation in several cases in the literature, though in some patients the underlying traumatic mechanism is difficult to establish. No relation to underlying clinical or biologic abnormalities appears to be. Seven patients with lipoatrophia semicircularis are described. A detailed clinical history revealed precipitating trauma in all cases. A review is made of earlier reports in the literature.

Bowenoid papulosis: clinical and histological study of eight cases.

Eight cases of bowenoid papulosis are reported. The clinical diagnoses were confirmed by histology. In one case an immunoperoxidase method showed the presence of papillomavirus antigen in the nucleus of the most superficial epidermal cells. We consider bowenoid papulosis to be a condition with specific features that distinguish it clinically and histologically from carcinoma in situ and condylomata acuminata.

[Non-gonococcal urogenital infections: etiology].

1,109 patients suffering from non-gonococcal urogenital infections have been studied. 63.4% of the patients had genital discharge. Microorganisms were found in 685 patients (61.8%), only one agent being isolated in 73.6% and two in 22.1% of the cases respectively. The rest of the patients had an association of three or more microorganisms. In women, the most frequently identified microorganism was Candida sp (29.9%), followed by U. urealyticum (20.5%) and G. vaginalis (19.7%). In men, U. realyticum (40.1%) was the most frequent followed by C. Trachomatis (21.4%) and M. hominis (16.6%).

[Non-gonococcal urethritis caused by Chlamydia trachomatis: factors affecting its incidence].

A retrospective study to investigate the relationship between the isolation of Chlamydia trachomatis and other factors occurring in 146 patients suffering of non-gonococcal urethritis, has been released 39 being positive for C. trachomatis. The relationship between the isolation of C. trachomatis and previous antibiotic treatment, age, sexual different contacts in the last month and year has been studied. The main feature affecting the isolation is the absence of antimicrobial therapy a previously to the specimen collection and being performed after four days post-contact.

Subcutaneous nodules following treatment with aluminium-containing allergen extracts.

We describe two patients who developed multiple itching nodules following immunization with vaccines adsorbed on aluminium hydroxide. Both patients had been treated with vaccines for extrinsic asthma and rhinitis for 4 and 10 years respectively. The lesions were persistent and lasted for several years. Histopathological findings were those of a foreign body reaction. Aluminium was most probably involved in the pathogenesis of these lesions because its presence could be demonstrated in macrophages using energy-dispersive X-ray microanalysis. Although some symptomatic relief was achieved with topical corticosteroids and oral antihistamines, treatment was unsuccessful.
