Chronic intussusception in children caused by Ascaris lumbricoides.

Chronic intussusception (CI) is defined as an intussusception lasting for 14 days or more. Because the clinical manifestations are non-specific, the diagnosis is usually delayed. Symptoms include intermittent abdominal pain, sometimes an abdominal mass is palpable and there is a marked weight loss.

The renal parenchyma evaluation: MAG3 vs. DMSA.

Scintigraphy with Tc-99m dimercaptosuccinic acid (DMSA) is considered a reference method for assessment of parenchymal lesions and estimation of differential kidney function. The aim of study was to evaluate Tc-99m mercaptoacetyltriglycine (MAG3) dynamic renal scintigraphy for the same purpose. 188 patients, submitted to both studies within three months, were divided in two groups.

[Congenital diaphragmatic hernia in older children].

The incidence of congenital diaphragmatic hernia (CDH) is about 4.8/10,000 live births. Its typical clinical presentation is respiratory distress occurring immediately after birth or in the first few hours or days of a child's life.

Congenital laryngeal cyst: one or two cysts.

The case presented is of a neonate with extreme respiratory distress immediately after birth, caused by a large laryngeal cyst. The vertical diameter of the cyst was larger than the height of the neonatal larynx. First excision of the cyst was performed in the region of the prominent aryepiglottic fold.
