McCune Albright Syndrome: A Diagnosis to be Kept in Mind

Precocious puberty, defined as the development of secondary sexual characteristics before the age of 8, often leads to anxiety in patients and their families but also in clinicians searching for the final diagnosis. After adequate investigation, the majority of the cases in girls turn out to be idiopathic. The authors present a case of McCune Albright syndrome in order to call attention to a rare cause of sexual precocity and the value of ultrasound in the evaluation of these situations. 10 years old infant girl admitted in our department due to irregular menstrual bleeding. She experienced a vaginal bleeding by the age of 3 which led to the diagnosis of McCune Albright Syndrome after a complete evaluation. Pubertal assessment revealed a reversed sequence in the remaining events with adrenarche at 5 and thelarche at 8. Hormonal evaluation demonstrated low FSH and LH levels (11,2 and 6,72 respectively) with high estrogen (204). Pelvic ultrasound showed a normal sized uterus (73x 29x32 mm), endometrial thickness of 5 mm and ovaries with several microfollicles and a copus luteum measuring 23 mm in the right ovary. McCune Albright syndrome is a very uncommon cause of sexual precocity that should, however, be suspected in all infant girls who present with vaginal bleeding. It is characterized by a triad: polyostotic fibrous dysplasia, gonadotropin-independent precocious puberty and café-au-lait skin spots. Due to autonomous production of estrogen by the ovaries, ultrasound image of the female reproductive tract is inconsistent with chronologic age. Pelvic ultrasound demonstrates a normal sized uterus with a well defined cervix and clearly identified ovaries with several follicles, similar to adult women of reproductive age. Ultrasonography of the pelvis has also an important role excluding other causes of GnRH-independent precocious puberty conditions like ovarian cysts or tumors

Human Rights in the Management Literature: Leading Publications and Research Agenda

This is the final version of the article. Available from Universidade Federal do Rio de Janeiro via the DOI in this record.This paper identifies and examines leading publications on human rights within the management literature. For that, we used features of a bibliometric analysis – specifically exploring product and impact indicators – in order to identify the leading publications on human rights that were examined aiming to portray how the issue has been addressed within this field. Moreover, by identifying the key articles and concepts adopted by the leading publications, this paper offers an interpretation of the academic context that enabled the emergence of a human rights approach within the management field. Thus, a contribution of this paper is to highlight how the debate on human rights in management has been strengthened, identifying articles and journals that can be a source of reference for future research. Our study has identified a shift in the discussion regarding human rights. During the last decade the topic, which was initially focused on the role of states in guaranteeing human rights, has started to examine the relationship between organizations and society. Such transformation has placed human rights as both, a responsibility and a duty of corporations. It is suggested that the literature on ethics and corporate social responsibility (CSR) was the entrance for a human rights approach within management literature. However, the discipline has already engaged in elaborating different interpretation of human rights. Our research shows the potential of human rights in consolidate a research agenda on corporate impact in our societies
