Our data suggest that hormone replacement therapy may exert a beneficial effect on ocular symptomatology, increase lachrymal secretion, reduce IOP, and increase corneal thickness.

The aim of this study was to evaluate bone metabolism in breast-feeding women. Thirty-six healthy women (24-31 yr, mean age 28.1 +/- 1.8 yr) were divided into 2 groups: group A including 18 women that exclusively breast-fed for 6 months, and group B composed of 18 women in whom lactation was inhibited with bromocriptine. Three days and 3, 6, and 12 months after delivery, distal radius, and lumbar spine bone mineral density (BMD) and some of the main biochemical parameters of bone turnover were assessed. In group A, we detected a significant decrease (P < 0.01 vs. basal and group B) in lumbar spine and distal radium BMD during breast-feeding. An incomplete recovery of BMD was detected 6 months after breast-feeding interruption. In group B, no significant changes occurred in BMD. In group A, during lactation, serum osteocalcin and urinary hydroxyproline showed a significant increase (P < 0.01 vs. basal and group B), while parathyroid hormone was significantly decreased (P < 0.02 vs. basal and group B). No significant variations in these parameters occurred in group B throughout the study. Our findings show that a significant decrease of BMD occurs during lactation and that this decrease is only partially recovered 6 months after interrupting breast-feeding.

The clinical effectiveness and safety of vaginal micronized progesterone treatment in mastodynia were evaluated in a double-blind placebo controlled study. Eighty regularly menstruating women affected by severe cyclical mastodynia were randomly assigned to two groups of 40 patients. One group was treated for 6 cycles from the 19th to the 25th day of the cycle with 4 g of vaginal cream containing 2.5% natural progesterone. The other group was similarly treated with placebo. The treatment was preceded by a control cycle. All patients reported every day their breast pain on a 100 mm visual linear analogue scale (VAS). The response of breast tenderness and nodularity to treatment was assessed by clinical examination. Vaginal progesterone resulted significantly more efficacious than placebo in reducing mean ratings of breast pain on VAS and mean scores of breast tenderness to touch. Success of treatment, defined as reduction greater than 50% of basal mean score of breast pain on VAS, was achieved in the 64.9% of patients treated with progesterone and in the 22.2% of patients receiving placebo (p < 0.01). Conversely, at the end of treatment, the improvement in breast nodularity showed a not statistically significant difference between the two groups. No major side-effects were detected.
