Melkersson-Rosenthal syndrome is a rare disorder characterized by a triad of recurrent orofacial swelling, recurrent paralysis of the facial nerve and lingua plicata. The complete triad only occurs in 25% of MRS cases. Monosymptomatic or oligosymptomatic variants are more frequent; other findings include granulomas in other facial sites, regional lymphadenopathy, fever, psychotic disorders and hyperplastic gingivitis are associated with MRS. This can be a diagnostic challenge. The etiology and pathogenesis of MRS are unknown. Corticosteroids or clofazimine appear the best therapeutic options.
Male and female mammals undergo profound hormonal changes during pregnancy, some of which are sufficiently dramatic to influence offspring survival. In order to understand the proximate mechanisms regulating the variability in reproductive success within and between individuals, we monitored changes in fecal corticosteroid concentrations over the reproductive cycle in male and female oldfield mice (Peromyscus polionotus subgriseus) to test whether corticosteroid concentrations during pregnancy were associated with offspring survival. In females that successfully raised litters to weaning, fecal corticosteroid concentrations were low until mid-gestation and increased significantly towards term; in females that did not raise their pups to weaning, fecal corticosteroid concentrations were significantly higher at mid-gestation, and remained high until late gestation. The difference in fecal corticosteroid concentrations at mid-gestation between successful and unsuccessful females can be explained by the fact that successful females were lactating. Lactation has been associated with a down-regulation of the hypothalamic-pituitary-adrenal (HPA) axis and, accordingly, a decrease in plasma corticosterone (CORT) in several species, including humans. Males that successfully raised their litters had low fecal corticosteroid concentrations throughout their partner's pregnancy. Unsuccessful males, however, had significantly higher fecal corticosteroid concentrations at term than males that raised their pups to weaning. While these preliminary data require further investigation, we suggest that pre-partum fecal corticosteroid concentrations in males were responsible for the variability in reproductive success.
