Cutis tricolor parvimaculata in two patients with ring chromosome 15 syndrome.

Two unrelated girls presented with multiple disseminated, paired, small café-au-lait spots and hypopigmented macules, suggesting didymosis (twin spotting). The girls also had growth retardation, microcephaly, hypertelorism, triangular facies, and a 46,XY, r(15) karyotype. The term cutis tricolor parvimaculata has been proposed to describe a twin spot phenomenon characterized by small, paired hypochromic and hyperchromic macules on a background of normal intermediate-pigmented skin.

Effects of short-term mild calorie restriction diet and renutrition with ruminant milks on leptin levels and other metabolic parameters in mice.

Objective: The adaptation of an organism to a calorie-restricted diet is characterized by metabolic, endocrine, and immunologic changes. The objective of this study was to determine, in a mouse model, the changes in serum leptin levels in response to short-term mild calorie-restricted and renutrition diets using different ruminant milks.

Methods: Weaned Swiss albino mice were fed with a mild calorie-restricted diet for 12 d, after which they were renourished with cow, goat, sheep, or buffalo milk for 7 d.

Oral and clinical characteristics of a group of patients with Turner syndrome.

Objective: The loss of the X chromosome in girls with Turner syndrome (TS) affects the shape and the size of craniofacial structures. Few studies have been reported on female patients with TS in South America. Records of odontologic alterations of 23 Argentinian patients with TS were compared with those of 25 girls in a control group, and associations were made with medical indications.
