[A method for studying the bone mass: dual-photon densitometry]. / Une méthode d'exploration de la masse osseuse: la densitométrie biphotonique.

The assessment of bone mineral mass during growth, periods diseases or therapy which modify bone mineralization in the child is of great interest. Single-photon absorptiometry carried out on forearm bones informs on the mineral density of the compact bone of the appendicular skeleton. It is easy to perform in children and infants. Dual-photon absorptiometry appears to be the most accurate for measuring bone mineral content in endocrine and metabolic bone disorders. The low dose of radiation and the non-invasive nature of this high-precision method render it well-adapted and suitable for measuring bone mineralization in childhood.

[Demonstration of tumour temperature variation during curietherapy for cancer of the uterine cervix (author's transl)]. / Mise en évidence d'une variation de température tumorale au cours d'une curiethérapie pour cancer du col de l'utérus.

We here describe a simple apparatus for measuring temperature, accurate to 3/100 of a degree, which makes it possible to follow variations in the temperature of an accessible internal organ, and we also describe its application to the observation of possible changes in the temperature of a tumour of the uterine cervix, during treatment by curietherapy.
