An analysis of the digito-palmar dermatoglyphs obtained from 231 inhabitants of the Island of Hvar, divided into two groups according to some sociocultural differences, is presented. The quantitative features do not reveal heterogeneity between the groups, while some qualitative palmar dermatoglyphic features are statistically significantly different. The results are discussed in the light of the possible influence of some different evolutionary processes.
The Aarskog syndrome is characterized by short stature, peculiar facies, shawl scrotum, cryptorchism, broad, short hands and hyperextensibility of the proximal interphalangeal joints. A boy with typical features of the Aarskog syndrome is presented. The proband's mother, sister and grandmother were short and strongly resembled him. Palmar dermatoglyphics showed the presence of whorls in the interdigital areas of the affected mother and son and the absence of this pattern on the palms of the sister.
The cause of a seventeen-year-old female patient with septo-optic dysplasia and pituitary dwarfism is presented. Mental retardatin and epilepsy, in addition to absence of the septum pellucidum, point to a widespread lesion of the central nervous system. There is unilateral hypoplasia of the optic nerve. She is of small stature. The dynamic pituitary tests point to deficiency of GH, TSH and ACTH, and an adequate reserve of prolactin, gonadotropins and vasopressin. TSH insufficiency is probably of primary pituitary origin.
The case of an 11-year-old girl with typical symptoms of focal dermal hypoplasia (Goltz-Gorlin syndrome) is reported. In a mentally normal child a mild body asymmetry with ocular, skin, dental, and skeletal changes, more pronounced on the right side, has been detected. A special contribution to the presentation is the dermatoglyphic finding of epidermal ridge hypoplasia on the fingertips of the right hand.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
