Return visits to the Paediatric Emergency Department: first analysis in Italy.

Return visits to the emergency room have come under scrutiny with a view to identifying the reasons for these events. The aim of the study was to estimate the incidence of return visits to emergency room and to compare this with data from other countries, with a view to proposing a method of monitoring this parameter nationwide. Ours is the first Italian study to report the incidence of return visits to the ER and to analyse the factors correlated with this phenomenon. The incidence of return visits within 72 hours of the first visit proved to be 2.5%. Statistical analysis revealed a significant difference in the number of return visits between patients under 1 year of age and those older than 1 year. Our future objective is to re-analyse recent case-records on the basis of the indicators identified, with a view to assessing the quality of the service.

Persistence of Müllerian derivatives and intestinal lymphangiectasis in two newborn brothers: confirmation of the Urioste syndrome.

We describe two newborn brothers with a pattern of malformation characterized by the persistence of Müllerian duct derivatives, intestinal lymphangiectasia, hypertrophied alveolar ridges, and early death. Postmortem examination showed the presence of a rudimentary uterus, fallopian tubes, the upper third of a vagina, a prostate of normal shape, a dilated colon, and generalized intestinal and pulmonary lymphangiectasia. The syndrome was first delineated by Urioste and co-workers [1993: Am J Med Genet 47:494-503]. These cases confirm the existence of a definite and distinct entity.

The Genoa experience of prenatal diagnosis in NF1.

Type 1 neurofibromatosis (NF1) is an autosomal dominant disorder with an incidence of about 1 in 3500 live births. Symptoms are highly variable from a few cafè-au-lait spots and axillary freckling to plexiform neurofibromas, optic gliomas, pseudarthrosis, and malignancy. Since disease causing mutations are dispersed throughout the gene, prenatal diagnosis is usually performed in familial cases by linkage analysis and rarely by direct characterization of the mutation. We have characterized 48 families and have performed four prenatal diagnoses. In three cases, the linkage analysis was carried out using informative markers. A direct approach using the protein truncation test (PTT) and sequencing was performed in one case in which a R1947X mutation was identified. The extreme variability of the phenotypic expression of the NF1 gene makes reproductive decisions in NF1 families very difficult, as molecular diagnosis cannot predict clinical expression of the disease. The psychological management of the couple is therefore difficult. In two of the three examined families the reproductive choices were not influenced by the specific manifestations of the disease in that family.
