[Neonatal hypocalcemia in 2 twins revealing maternal hyperparathyroidism. A review of the literature].

The authors report the case of dizygotic twins suffering from transitory neonatal hypoparathyroidy and leading to the diagnosis of maternal hyperparathyroidy. The differences of clinical and biological symptomatology between these twins suggest individual variations in response to phosphocalcic disorders of the mother. A review of literature find 31 other cases. This study emphasize the aggravation by the mild hypomagnesemia frequently associated, the usual severity of initial clinical symptomatology in contrast with a good neurologic outcome, the diagnosis of maternal hyperparathyroidy.

[Epileptic apneas in the neonatal period].

On the occasion of the reports of 6 cases, the authors summarize the clinical and electro-encephalographic features of apneic seizures, the value of polygraphic recordings to detect them, their poor prognosis and the contra-indication of xanthine treatment.

[Intra-uterine gestational age. The value of calcification of dental crowns (author's transl)].

Calcification in the first decidual molar tooth first appears at the 33-34th week of gestation; and the second at the 36-37th week. It is therefore a stable and precise index of gestational age. It can be estimated in over two-thirds of films of the intra-uterine contents chosen at random. The search for this sign can complement or take the place of looking for epiphyseal centres in the knee. It gives information about gestational age in pathological conditions where bony maturation is abnormal.

[Ectodermal anhidrotic dysplasia (author's transl)].

The E. A. D. is a genodermatosis characterised by absence or important diminuation of sweat glands. The study of 3 children of different families allows us to identify the diagnostic elements: typical facial signs, anhidrosis, rarity of teeth "buds", abnormalities of dermatoglyphes. This diagnosis must be established early, to protect the newborn from accidents of overheating caused by perspiration insufficiency. The sweat glands are not affected alone: exocrine glands also, explaining the fragility of the upper respiratory tract in such patients. The teeth abnormalities are important and need replacement by false teeth, carefully done at an early date and continued later on. Genetic investigation is indispensable to discover women who carry the disease, with a high risk of transmission to their children.
