During 2006, 82 samples of human mature milk were collected at Italian hospitals and checked for aflatoxin M1 (AFM1) and ochratoxin A (OTA) by immunoaffinity column extraction and HPLC. AFM1 was detected in four (5%) of milk samples (ranging from < 7 ng/L to 140 ng/L; mean level: 55.35 ng/L); OTA was detected in 61 (74%) of milk samples (ranging from < 5 ng/L to 405 ng/L; mean level: 30.43 ng/L. OTA levels were significantly higher (p less, not double equals 0.05) in milk of habitual consumers of bread, bakery products and cured pork meat. No other statistically significant differences were observed although habitual consumers of pasta (p = 0.059), cookies (p = 0.061) and juices (p = 0.063) had mean contamination values of OTA higher than the moderate consumer. The very few AFB1 positive samples did not allow statistical comparisons. The present study confirms that the occurrence of OTA in human milk is related to maternal dietary habits. The findings support the possibility of dietary recommendations to woman, during pregnancy and lactation, aimed to tentatively reduce the OTA contamination of human milk.

Hemi-hydranencephaly is a very rare condition characterized by complete or almost near-complete unilateral absence of the cortical cortex, which is filled by a sac of cerebrospinal fluid. Prenatal vascular disruption with occlusion of the carotid artery territories ipsilateral to the damaged brain is the presumed pathogenesis.We have selected nine cases that fit the clinical and pathologic characteristics of hemi-hydranencephaly, demonstrating that destruction of one hemisphere may be not always associated with severe neurologic impairment and may allow an almost normal life. This disorder is an example of a possible prenatal re-organization in which the right and left cerebral hemispheres present functional potentiality to make up the damaged brain.The cases reported in the literature are discussed, including a patient previously reported and followed-up for 10 years. A review of the cases is performed with an evaluation of the most important aspect of this rare and mysterious disorder.

Mucopolysaccharidosis type III (Sanfilippo syndrome) is an autosomal recessive disorder characterised by progressive nervous system involvement with mental retardation, behavioural problems and seizures. Three patients, of 20 months to 12 years of age, were followed up for 3 years both clinically and by using brain magnetic resonance imaging (MRI). Our results suggest that in MPS III patients MRI findings, including atrophy and abnormal or delayed myelination, may precede the onset of overt neurological symptoms. The increasing neurological morbidity is accompanied by different degrees of progressive atrophic changes, mainly affecting the cerebral cortex and the corpus callosum. However, it appears that, across subjects, the rate of MRI changes is unrelated to the severity of the clinical phenotype. On this basis it could be argued that in MPS III the worsening of the neurological symptoms might not necessarily reflect only the progressive cerebral abnormalities detectable by MRI.

Background: The ability to detect the spatial characteristics of objects and to rotate them mentally is frequently impaired in early treated congenital hypothyroidism (CH) children. Aims: To explore the neural substrate of the visuospatial difficulty in children with CH, we studied 15 children with CH (8–10 years) and 13 age-matched control children with functional magnetic resonance imaging (fMRI) using a mental rotation task (VST). Results: Performance at VST was significantly different between the two groups. Moreover, fMRI data showed greater activation in the superior parietal cortex in control children while children with CH had greater activation in the bilateral SMA and the opercular region of the precentral gyrus, the adjacent insula and the left somatosensory parietal cortex. Furthermore, children with CH deactivated the inferior parietal cortex (Brodmann area 40) more than controls. Conclusion: We suggest that the poorer performance of children with CH on VST task is related to the decreased activation in brain areas important for the mental representation of the objects’ spatial characteristics, with increased recruitment of regions involved in the representation of somatosensory whole-body information. More studies will be necessary to understand if this different effectiveness in VST reflects immaturity of the neural system or its actual impairment.

We found that high-frequency oscillatory ventilation in very low birth weight infants without antenatal glucocorticoid prophylaxis reduced the need of ventilatory support, surfactant therapy, and reintubation, and shortened neonatal intensive care unit and hospital stay, thus reducing unit and hospital costs. These data would support the usefulness of first intention high-frequency oscillatory ventilation strategy in managing in a selected population, such as very low birth weight newborns complicated by severe respiratory distress syndrome not antenatally treated with glucocorticoids.
