ABSTRACT
BACKGROUND: Sexting has recently emerged as a public health and social issue. The present study had two aims: a) to preliminarily test adolescent gender differences on parental practices regarding adolescent online life, parental monitoring, adolescent attitude towards sexting and sexting behaviors; b) to separately test for male and female adolescents a conceptual model in which sexting behaviors are explained by the parental practices and monitoring, with the mediation of adolescent negative attitude towards sexting. METHODS: Direct and indirect links between the variables in the model were investigated. The study was carried out with 541 participants. Participants were Italian adolescents (60% males; 40% females) aged 14 to 19 years (Mage = 16,19 years, SDage = 1,31). RESULTS: Results suggested that females sent more multimedia sexts, had a higher perception of risk associated with sexting and reported higher scores for both parental practices regarding adolescent online life and parental monitoring. Rules on Contents, Parental Knowledge, Adolescent Disclosure, and Parental Control resulted to be linked to both sexting attitudes and behaviors for male and female adolescents. CONCLUSIONS: Findings emphasize the important role that parents play in shaping attitudes and behaviors of both daughters and sons during adolescence.

The authors report the clinical and radiographic results of 57 patients operated on for recurrent dislocation of the shoulder by the Delitala method. The age at operation ranged from 16 to 45 years. The follow-up was an average of 10 years (minimum 1, maximum 25 years) and the results were good or excellent in most of the cases. The failures included one case of recurrence and two of stiffness.

A family is described in which a reciprocal translocation involving 5p and 21q appeared de novo in the chromosome complement of a woman who then transmitted it in both balanced and unbalanced form to her progeny. The proposita, a child with the cri du chat syndrome, had a deficiency for most of 5p, all of 21p, 21 centromere, and a small proximal segment of 21q. The reported cases of the cri du chat syndrome associated with translocations are reviewed and discussed in relation to this family.

The bilateral absence of testes is described in one of two otherwise healthy and well-developed 12-year-old identical twin boys. The twins' father has only one palpable testis. The occurrence of complete anorchia in only one of otherwise identical twins constitutes relevant new data for considering the etiology of this rare condition and in assaying the role of the testis in growth and development between birth and puberty.

De novo structural rearrangement of the Y chromosome was discovered in one cellular component of a mosaicism in each of three individuals. In each case another cellular component had lost the Y chromosome completely and was monosomic (45,X). Consideration of these three observations, in light of the regularity with which an association has been reported previously, led to the formulation of a concept to explain, in terms of a single disruptive cytogenetic event in the zygote or an early postzygotic cell, the simultaneous derivation of a cell with an abnormal Y and a monosomic sister cell devoid of a Y completely. An intrachromosomal rearrangement affecting the Y is proposed to give rise to one rearranged Y and to one acentric Y fragment. The unlike sister cells derived would be progenitors of two abnormal cellular components of a mosaic embryo. Should the rearrangement occur in a postzygotic cell, a third and normal (46,XY) component would be represented as well.

A man (46,XY) is described with an intraabdominal uterus and fallopian tubes. His testes, each of which contained a gonadoblastoma, occupied the intraabdominal adnexal position, leaving the scrotum empty. His external genitalia were unambiguously male. A vagina opened into the urethra. His presenting complaint was inguinal hernia. This developmental defect has been described previously, but genetic aspects and its relation to other conditions, "mixed" gonadal dysgenesis in particular, remains obscure pending the recognition and reporting of more cases studied in the light of recent cytogenetic advances.
