BACKGROUND Tourette syndrome (TS) is characterized by dysfunctional connectivity between prefrontal cortex and sub-cortical structures, and altered meso-cortical and/or meso-striatal dopamine release. Since time processing is also regulated by fronto-striatal circuits and modulated by dopaminergic transmission, we hypothesized that time processing is(More)
The Authors describe a case of chest wall hamartoma, very rare in infants and usually present at birth. This lesion, histologically, is benign. Surgical ablation is mandatory and curative, but the ablation of the tumor and the reconstruction of the large residual parietal defect are sometimes very difficult. In this case the surgical treatment was(More)
We report two cases of perirenal urinary extravasation one of which associated with urinary ascites. An underlying congenital obstructive uropathic condition was discovered in both patients. A localised parenchymal perforation was found in both cases. Prompt treatment with correction of metabolic acidosis and decompression of the tense abdomen and the(More)
A range of epididymal and vasal anomalies (EVA), varying from ductal patency aberrations to abnormal attachments of the epididymis to the testis or even complete absence, exists in boys with cryptorchidism, but there are few studies of normal controls for comparison. In the present study anatomy of testicular-epididymal relationships were recorded in 517(More)
The term medullary sponge kidney refers as a renal parenchymal malformation characterized by cystic dilatation of the collecting ducts. Although medullary sponge kidney is a congenital disease, it is rarely identified in childhood and is usually discovered in adulthood. We report a child with bilateral medullary sponge kidney who, in addition to typical(More)
Fifty-four cases of anomalies of position in 52 children were reviewed. Of the 52 children 24 (46%) had anomalies involving organs outside the urinary tract and contralateral renal units. Twenty-five ectopic kidneys showed major urological complications (46%). Four were treated conservatively and 21 with surgery. The postoperative results have been(More)
Crossed testicular ectopia is a congenital anomaly characterized by the presence of both testes in the same hemiscrotum and may be associated in 20% of the cases with genitourinary developmental abnormalities. This review underscores the complexities of assessment and surgical management of an uncommon case in which crossed testicular ectopia and true(More)
The tethered cord syndrome is a form of spinal dysraphism in which a short, thickened filum terminale prevents the ascent of the conus medullaris and intraspinal lipoma causes compression upon the caudal part of the spinal cord. In pediatric age the first symptoms are urological: urinary incontinence and infection. Diagnosis is performed with urodynamic(More)
Hydronephrosis in infancy and childhood is a frequent urinary malformation and is almost always congenital. In over 80% of the cases it is due to ureteropelvic junction obstruction; in about 17%, anomalous renal vessels at the ureteropelvic junction are present. The authors analyze their experience in the surgical treatment of hydronephrosis. 360(More)
