Several anthropometric parameters (weight, height, thickness skinfolds, and body circumferences) together with the bioelectric impedance (BIA) were measured in a group of 407 healthy prepuberal children (205 males, mean age +/- SD: 6.8 +/- 1.6 years; 202 females, mean age +/- SD: 6.6 +/- 1.6 years) who did not practice any competitive sport. The group was divided into six weight classes (underweight to obese 3). The average values of the anthropometric data, BIA, FM (which is derived from the thickness skinfolds and BIA), TBW (derived from BIA), AFA and AMA (both derived from the forearm circumference and triceps skinfold) were all evaluated in relation to sex and weight classes. The average values of all the measured thickness skinfolds, FM and AFA were higher in the females. When considering the body circumferences, only the wrist circumference showed a statistically significant difference between sexes, being higher in males. In contrast both the rates waist/hips circumferences and waist/thigh circumferences were higher in males. As far as the BIA and FM average values is concerned, these were higher in females. The average value of FM derived from measuring the thickness skinfolds (males = 17.65 +/- 4.89%: females = 23.81 +/- 4.72% of body weight) proved higher than that one derived from BIA (males = 17 +/- 9.02%; females = 19.27 +/- 9.18%). The analysis of anthropometric and BIA data in relation to the weight classes showed significant variations of the mean values, except the rates waist/hips circumferences and waist/thigh circumferences. Therefore our data seem to exclude the presence of any difference of the fat distribution between sexes in paediatric age.(ABSTRACT TRUNCATED AT 250 WORDS)

[The usefulness of the skeleton in the diagnosis of malformation].

Most malformation syndromes (70%) show evidence of skeletal anomalies, mainly in the vertebral bodies and in the bony segments of the limbs. This explains the importance of studying the skeleton when faced with any multi-malformation syndrome, using techniques like CT, MRI, echography and densitometry as well as standard radiology. To increase the quantity of information available for diagnostic purposes it would be profitable to create a data bank containing all the possible radiological findings encountered in the numerous multi-malformation syndromes.

[Central pontine myelinolysis as potential complication of cerebellar astrocytoma: report of a case].

Central pontine myelinolysis (CPM), a rare condition first observed by Adams et al. in 1959 in a group of malnourished chronic alcoholic subjects, has subsequently been seen in patients treated with thiazide diuretics, patients hyperhydrated postoperatively, and in other clinical situations. it is characterized by quadriplegia and pseudobulbar palsy which sometimes evolves into a locked-in syndrome. The rapid correction of severe hyponatremia (> 12 mmol/L/24 h) seems to be the causal factor, with consequent osmotic edema in the richly vascularized white matter of the pons as the proposed pathogenetic mechanism. We describe the case of a chronic psychotic man with nutritional disorders and inappropriate water intake who came to our attention for a clinical picture of CPM. Neuroradiological findings and postmortem studies revealed a slow-growing cerebellar astrocytoma in addition to the typical features of CPM. We discuss the hypothesis that damage to the nervous pathways and centers involved in water and electrolyte regulation could be the causal factor of CPM pathogenesis in this case.
