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.
