The authors report the case of an term infant weighing 2,860 kgs, who presented with failure to thrive during the two first months of life. Clinical features suggested the diagnosis of leprechaunism. After a review of the literature, the authors conclude that the diagnosis of this rare condition is essentially a clinical one, as there are no specific laboratory tests.

The association of hypercalciuria, salt losing renal disease, and a defect in urine concentrating ability with high renin and aldosterone levels is described in two brothers. One child had marked nephrocalcinosis by the age of 3 and the other severe growth retardation. In one child all the abnormalities were abolished with indomethacin which was responsible for a marked decrease in urinary. The data and the family study suggest that this condition is a proximal tubular disorder with atuosomal recessive inheritance.
Three observations of R.T.A. with nerve deafness are reported. Case 1 and 2 concern consanguinous brothers whose parents are not affected, which confirm the syndrom as an autosomal recessive entity. The third, sporadic, case relates to a 13-year-old non consanguinous girl. Metabolic abnormalities and renal evolution with nephrocalcinosis was such as in Albright disease. However a progressive nerve deafness makes distinction. The authors underline the importance of this sometimes difficult distinction for genetic counseling.

A clinical report of a typical case of infantile Gaucher's disease is given. Study of the beta-glucosidase activity in leukocytes and skin fibroblasts confirmed the diagnosis in the patient and established the heterozygote condition of the parents. Two later pregnancies have been monitored by enzymatic study of cultured amniotic fluid cells. Both foetuses were predicted to be healthy, which was confirmed after birth. The report includes a histopathological ultrastructural, chemical and enzymatic study of liver, spleen and brain obtained at autopsy. Possible clues to the physiopathological mechanism of the cerebral lesion are discussed.
Two children, born to related parents, presented since birth a muscular defect rapidly complicated by painful joint stiffness. The oldest child died at 6 months of age, from respiratory complications. The second-14 month old- does not sit without support. The muscle fibres are of unequal calibre and numerous fibres have under-sarcolemmal PAS positive areas contain glycogen, as seen on electron microscopy. In the second patient, the biochemical analysis showed a moderate glycogen accumulation and muscular enzymatic studies demonstrated an isolated and major deficiency in phosphofructokinase activity. Activity was normal in red blood cells and in fibroblasts cultured in vitro. Hence, these cases should be distinguished from formerly reported cases of phosphofructokinase deficiency. This type of P.F.K. deficiency should be looked for in patients with severe congenital muscular dystrophy and early joint involvement.

Report of 3 cases of propionic acidemia which concern one boy (O.M.) in whom a formed diagnosis of hyperglycemia with ketosis had been established, and two sisters (C.V. and K.V.) of another family. The activities of propionyl-CoA carboxylase in O.M. and C.V. fibroblasts were reduced to 4.5 and 2.5% of control. After two severe metabolic crisis, at 6 and 44 months of age, O.M. has at the present time (11yrs) a normal psychical development, and very few neurological disorders. Propionic acidemia was manifested only at 34 months of age in C.V. with a very severe crisis of acidoketosis with hypoglycemia, leading to neurological sequellae which are still important at 56 months of age. The disease was entirely latent in K.V. at 26 months, when the diagnosis was proven; it remains latent at 40 months. These case reports represent a special form of propionic acidemia with late clinical expression. Biological evolution does not seem to be affected by prolonged administration of biotine.
