RESUMEN
We discuss the anatomic and pathophysiological patterns of preterm and term newborn. Particular attention is directed to technical artefacts relating to the interpretation of chest radiography. We analyze the reading of chest X-Ray of preterm with low birth weight and poor lung maturation. Are also taken into account X-Ray features relating to alveolar "recruitment" and radiographic changes after surfactant's administration. We highlight the most important paintings of bruncopulmonary dysplasia and its evolution. The most frequent neonatal pulmonary inflammation and thoraco-pulmonary malformation, that may affect more the neonatologist, are mentioned. We discuss the new diagnostic approach with non invasive techniques (ultrasound) in the neonatal distress. Some easily recognizable congenital heart disease are finally describes.

RESUMEN
PURPOSE: To assess the value of Computed Tomography (CT) in the diagnosis and in morphologic characterization of metastatic melanoma. MATERIALS AND METHODS: The data of total body CT of 124 consecutive patients with melanoma having a Breslow index 1 mm or a positive sentinel lymph node have been retrospectively reviewed. RESULTS: The CT scan showed loco-regional and/or distant metastases in 36 patients (39%). Ten of these (28%) had metastases only to lymph nodes, whereas 26 patients (72%) had multiple metastases. Nodal, pulmonary, brain, subcutaneous, hepatic, adrenal, bone, gastrointestinal, breast and abdominal wall metastases were detected in 80.6%, 47.2%, 25%, 25%, 16.7%, 13.9%, 11.1%, 5.6%, 5.6% and 2.8% of the patients respectively. All the patients with metastases also had a positive sentinel lymph nodes and/or symptoms of metastatic disease. CONCLUSIONS: CT fails to reveal any characteristic feature of metastatic melanoma, but it is of value in the diagnosis of loco-regional and distant metastases in III stage disease.
