The impact of a monophasic continuous estro-progestogenic treatment on Latin American menopausal women.

Objective: The present study was undertaken to assess the impact, effectiveness and safety of a monophasic hormone replacement treatment (HRT) for continuous use with regards to the clinical effects, bleeding patterns and lipid profile of menopausal women in four Latin American countries.

Design: Three hundred and six postmenopausal women with natural menopause and uterus present were recruited. This was a multicentre prospective, clinical trial; the participating countries were Brazil (BR), Colombia (CO), Mexico (MX) and Argentina (AR).

A 13-month multicenter clinical experience of a low-dose monophasic oral contraceptive containing 20 microg ethinylestradiol and 75 microg gestodene in Latin American women.

This prospective, multicenter study was conducted to evaluate the contraceptive reliability, cycle control and tolerability of a 21-day oral contraceptive regimen containing 20 microg ethinylestradiol and 75 microg gestodene in four Latin American countries (Mexico, Argentina, Brazil and Colombia). Participants took trial medication daily for 21 days. Contraceptive efficacy, cycle control and tolerability were evaluated over a period of 13 cycles.

Latin american experience with two low-dose oral contraceptives containing 30 microg ethinylestradiol/75 microg gestodene and 20 microg ethinylestradiol/150 microg desogestrel.

The objective of this study was to compare cycle control, efficacy and tolerance of an oral contraceptive containing 20 microg ethinylestradiol and 150 microg desogestrel with a preparation containing 30 microg ethinylestradiol combined with 75 microg gestodene. This study involved 342 women and 4104 cycles use in Argentina, Brazil, Chile, and Mexico. Contraceptive efficacy was good with both formulations.

Mesigyna once-a-month combined injectable contraceptive: experience in Latin America.

A phase III clinical study was carried out among 534 fertile Latin American women to evaluate cycle control, side effects, and contraceptive efficacy of a once-a-month combined injectable, Mesigyna, consisting of 50 mg norethisterone enanthate and 5 mg estradiol valerate. The pregnancy rate at 1 year was 0 per 100 woman-years for a total experience of 4688 woman-months. The overall discontinuation rate at one year was 17.

Cytokine expression is downregulated by collagen-polyvinylpyrrolidone in hypertrophic scars.

We evaluated the in situ expression of adhesion molecules (E-selectin and vascular cell-adhesion molecule) and proinflammatory/fibrogenic cytokines (IL-1beta, TNF-alpha, TGF-beta1, and PDGF) in sections of normal skin, hypertrophic scar, and hypertrophic scar previously treated with an irradiated mixture of collagen-polyvinylpyrrolidone and completely resolved. Expression of these proteins was detected by indirect immunoperoxidase staining. The hypertrophic scar group displayed an increased amount of IL-1beta, TNF-alpha, TGF-beta1, and PDGF compared with the normal skin and treated scar groups.
