Pyrethroid insecticides have been used for more than 40 years and account for 25% of the worldwide insecticide market. Although their acute neurotoxicity to adults has been well characterized, information regarding the potential developmental neurotoxicity of this class of compounds is limited. There is a large age dependence to the acute toxicity of pyrethroids in which neonatal rats are at le...

We review the main concerns related to the management of menstruation in adolescent females with developmental delay. Results from a questionnaire evaluating the current practice of menstrual control in developmentally delayed females by pediatric endocrinologists are also summarized. Guidelines for clinical care are provided, taking into account the specific health issues of this particular pa...

This paper outlines the epigenetic logic of the emergence and elaboration of symbolization. The account is based upon considerations arising from the study of the ontogenesis and phylogenesis of symbolic communication, abstraction from which yields generalizations regarding the necessary developmental pre-requisites for the capacity for symbolization and the processes of the elaboration of symb...

The aim of the thesis is to offer a comprehensive account of the developmental course of hand-mouth (HM) coordination from birth until a mature form of the coordination is attained. Questions relating both to the structure and function of the coordination were

There is no need to stress the very close developmental connection between the urinary and generative systems. I have felt however that in our wards and theatres the clinical and pathological connection might receive more attention, not merely on account of its very great technical interest, but also because recognition and correction of injuries and disorders of the urinary organs can be of in...

Fuzzy-trace theory has been developed by Brainerd and Reyna (1998, this issue) to explain a variety of findings. Here we explore the way that fuzzy-trace theory handles three phenomena concerning the creation and maintenance of false memories. We show that fuzzy-trace theory can account for seemingly paradoxical findings, thus providing theoretical clarity that has heretofore been lacking in th...

Human newborns can resolve some response conflicts in order to adapt their behaviour, suggesting that the newborn has consciousness according to Morsella et al.'s framework. However, we pose a range of developmental questions regarding Morsella et al.'s account, especially concerning the role of consciousness in the development of action.

The evolution of the concept of child abuse leads to consider new types of maltreatment that in the future will certainly be taken into account with a new era of social pediatrics.Pediatric care has been based on the increased awareness of the importance of meeting the psychosocial and developmental needs of children and of the role of families in promoting the health.

Consciousness has a number of apparently disparate properties, some of which seem to be highly complex and even inaccessible to outside observation. To place these properties within a biological framework requires a theory based on a set of evolutionary and developmental principles. This paper describes such a theory, which aims to provide a unifying account of conscious phenomena.

In this paper I argue that reference to a developmental account of agency can help explain, and in cases also alter, our current practices when it comes to the non-consensual medical treatment of children. It does this through its explanation of how stages of development impact the types of interests we have.
