Neonatal ischemic limb lesions: From etiology to topical nitroglycerine. A case series analysis.

Although rare, ischemic lesions in neonates may occur in Neonatal Intensive Care Units (NICUs) secondary to routine procedures and/or medicaments. We present double-center case series, reporting three preterm neonates with ischemic lesions following cardiac arrest and radial blood sampling. The overall outcome after treatment with 2% nitroglycerine (NTG) ointment showed optimal results with no adverse events.

Time processing in children with Tourette's syndrome.

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 abnormal in TS.

Methods: We compared time processing abilities between nine children with TS-only (i.

[Cryptorchidism: anomalies of the secretory ducts and azoospermia].

A range of epididymal and vasal anomalies (EVA), varying from ductal patency aberrations to abnormal attachments of the epidydimis 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 cryptorchid patients (423 unilateral and 94 bilateral) and in 192 boys who underwent inguinal exploration for inguinal hernia or hydrocele. The postmortem anatomic relationship of the testis and epididymis in 50 adults was also examined.

[Renin-dependent arterial hypertension in polycystic kidney operated on at a late period].

A case of a 17 year-old male patient developing renin dependent hypertension 3 years after nephrectomy for multicystic dysplastic kidney is reported. The risks of arterial hypertension in adolescence and adulthood as well as malignancy strongly suggest, at least in our opinion, precocious prophylactic nephrectomy.

[Medullary sponge kidney with severe renal function impairment: a case report].

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 urographic findings, presented an unfavorable evolution that ended in renal chronic insufficiency.

[Cryptorchidism: anomalies of excretory ducts and azoospermia].

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 cryptorchid patients (423 unilateral and 94 bilateral) and in 192 boys who underwent inguinal exploration for inguinal hernia or hydrocele. The postmortem anatomic relationship of the testis and epididymis in 50 adults was also examined.

[True hermaphroditism in crossed testicular ectopy: report of a case].

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 hermaphroditism are simultaneously described.

[Mesenteric lymphangioma: report of a case].

Lymphangiomas are benign tumours that appears to arise from congenital malformation of the lymphatics. They are most commonly reported in the head and neck regions. The clinical presentation, diagnosis and treatment of a rare case of mesenteric lymphangiomas are reviewed.

[Spontaneous and traumatic rupture of the renal parenchyma in primary obstructive megaureter: a report of 2 cases].

Urinary extravasation in infants may occur secondary to a variety of congenital obstructive uropathic conditions. This condition has been reported most often in infants with posterior urethral valves and pelviureteral junction obstruction. We present two cases of perirenal urinary extravasation from the kidney due to primary obstructive megaureter.

[The urological complications of renal ectopia in childhood].

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%).

[Chondroid hamartoma of the thoracic wall: apropos of a case treated by extensive surgical exeresis].

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.

[Paraesophageal inflammatory pseudotumor in an 11-year-old girl].

Paraesophageal inflammatory pseudotumor is the cause of anaemia and intermittent fever. The surgical treatment determines a rapid and complete clinical resolution.

[Nephroblastoma with prevalent rhabdomyosarcomatous component. Description of a case with early cerebral metastasis].

The malignant rhabdoid tumor of the kidney determines clinical and prognostic evaluations due to the poor therapeutic answer and to the uncertain prognosis. The Authors describe a case of nephroblastoma with anaplasia of the blastemal elements associated to rhabdomyosarcoma areas.

[Neonatal perirenal urine extravasation and urinary ascites associated with obstructive uropathy].

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.

[Hydronephrosis in childhood. Long and mid-term morphologic and functional results].

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.

[Retrotendinous ureter. An exceptional cause of obstruction in the upper urinary tract].

Retrotendineus ureter is an exceptional anomaly presenting, in our experience, without clinical signs of urinary infection and obstruction. The radiological diagnosis was retrocaval ureter. The Authors report a case of a 9 years old boy who was successfully treated by ureteral section, excision of the obstructed ureteral segment and uretero-ureteral anastomosis.

[A rare cause of occult neuropathic bladder in children: the tethered cord syndrome].

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 studies followed by nuclear magnetic resonance.

[Inflammatory pseudotumor as a cause of obstructive jaundice. Report of a case in a child].

Inflammatory pseudotumor involving the common bile duct, is a very rare event. The Authors were able to observe such a case in a 10 year old boy and report here the peculiar clinical findings.
