[An unusual pneumomediastinum case in a child caused by spontaneous bronchial rupture]. / Un insolito caso di pneumomediastino in un bambino da rottura spontanea di bronco.

We report a case of spontaneous pneumomediastinum (SPM) in a 3 year-old child, admitted to the emergency department because he presented dyspnea for a few hours, after a paroxysm of cough. The SPM is rare in children; the term "spontaneous" is reserved for cases of pneumomediastinum that haven't a traumatic cause. SPM is seen most commonly in asthmatics and in any patient who induces a Valsalva maneuver. The clinical diagnosis is confirmed by chest radiograph. When the diagnosis is uncertain, the chest CT scan is considered the gold standard of imaging tests, capable of detecting pneumomediastinum even in patients with small amounts of mediastinal air. In this case CT images showed the cause: spontaneous bronchial rupture. The direct sign of bronchial injury is the contiguity of the luminal air with that in the mediastinum. In the literature SPM cases are very rare, at least in health patients without tracheobronchial anomalies. The SPM is generally a benign entity that requires supportive care, and resolution occurs spontaneously, such as in our patient. In this article we want to explain the main clinical, diagnostic and therapeutic aspects of SPM, because, even if it's rare in children, it must be considered in the differential diagnosis of dyspnea; then we want to demonstrate as, in this case, a TC scan was important to identifying the SPM cause: a bronchial rupture.

[Congenital megacystis in a female fetus. Case report]. / Megavescica in feto di sesso femminile. A proposito di un caso.

The Authors report a case of congenital megacystis without other anomalies, diagnosed in a 27GW female fetus. At prenatal counselling the diagnostic hypothesis formulated were obstructive uropathy (cloacal malformation, uro-genital sinus, urethral atresia), functional alteration (neurogenic bladder, primitive myopathies) or Prune Belly Syndrome (rare in females). The outcome following treatment suppose a visceral myopathy, for this condition, however definitive etiology is obscure.
