Prenatal diagnosis and prognosis of triple X syndrome: 47, XXX.
ABSTRACT Triple X syndrome is a relatively common sex chromosomal abnormality occurring in 0,1% of live-born female infants. Most of these infants have a normal phenotype and only a few cases with 47, XXX karyotype have congenital malformations. We report three cases of triple X syndrome that were diagnosed prenatally by genetic amniocentesis for advanced maternal age and have been observed from birth to age of 3 to 12 years. A description of their growth and development is presented. The birth weight was normal in all patients and one of them had facial dysmorphism with right microphtalmia and auricular septal defect. During the first 2 years of life, the neuromotor development of these infants was not distinguishable from chromosomally normal children. By 3 years of age, two patients have a moderate developmental delay in speech and language. One girl 12-year-old had normal schooling. The diagnosis of the triple X syndrome can be never made because clinical demonstrations are not rather important to arouse the demand of a karyotype. Prenatal diagnosis is often made in front of the advanced maternal age. Expectant parents must be counseled as to the significance of this 47, XXX karyotype and prognostic information must be given.

ABSTRACT: Artificial neural networks are an established solution for classification. Many neural networks consist of perceptrons (e.g. multilayer-perceptron networks). In this paper, we propose a concept to extract reliability information of a perceptron-based neural networks decision. Therefore, we extend the conventional perceptron and suggest a simple training strategy.Signal Processing, 2004. Proceedings. ICSP '04. 2004 7th International Conference on; 10/2004

ABSTRACT: To report the responses to IVF surrogacy attempts in a female with a heretofore never described combination of Mayer-Rokitansky-Kuster-Hauser (MRHK) syndrome and triple X karyotype. Case report. Reproductive unit of a university-affiliated medical center. A 29-year-old female diagnosed as having both MRHK syndrome and a triple X (47XXX) karyotype. Five cycles of IVF surrogacy. Recovery of oocytes after controlled ovarian stimulation. A maximum of five oocytes were retrieved by percutaneous abdominal aspiration of a single subcostal left ovary. After five unsuccessful IVF trials due to low ovarian response attributed to her coexisting MRHK syndrome and triple X karyotype, the patient's choice was oocyte donation. An abnormal karyotype can coexist with MRKH syndrome, albeit very rarely, and probably accounts for a low ovarian response to attempts to achieve IVF surrogacy.Fertility and sterility 12/2010; 95(5):1788.e11-3. · 3.97 Impact Factor

ABSTRACT: To the best of our knowledge, this is the first report of a comorbidity between Gilles de la Tourette's syndrome and 47 (XXX) syndrome. The clinical picture of Gilles de la Tourette's Syndrome is well described, while 47 (XXX) syndrome is much more rare and has a broader spectrum of possible phenotypic presentations. An Italian Caucasian girl was referred at the age of 11 to our Rehabilitation Center for anxiety and learning difficulties. The girl had already been diagnosed as having 47(XXX) syndrome; she had some rather typical features of the chromosomal abnormality, but she also showed a high level of anxiety and the presence of motor and vocal tics. When an accurate history was taken, a diagnosis of Gilles de la Tourette's Syndrome emerged. The possible interaction between peculiar features of these two syndromes in terms of neuropsychological and affective functioning is both interesting for the specific case and to hypothesize models of rehabilitation for patients with one or both syndromes. Executive functions are specifically reduced in both syndromes, therefore it might be hard to discriminate the contribution of each one to the general impairment; the same applies to anxiety. Moreover, mental retardation (with a significantly lower verbal cognitive functioning) poses relevant problems when suggesting cognitive behavioral or psychoeducational rehabilitative approaches.Journal of Medical Case Reports 11/2011; 5(1):542.
