An unusual location of hand, foot and mouth disease.

Hand, foot, and mouth disease (HFMD) is a childhood febrile disease. Oral lesions and papulovesicular lesions on the hands and feet are the clinical signs of the disease. In our case, a 17-year-old boy presented to the emergency department, where he was diagnosed with HFMD.

Diagnostic imaging in COVID-19 pneumonia: a literature review.

In December 2019 in Wuhan (China), a bat-origin coronavirus (2019-nCoV), also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was identified, and the World Health Organization named the related disease COVID-19. Its most severe manifestations are pneumonia, systemic and pulmonary thromboembolism, acute respiratory distress syndrome (ARDS), and respiratory failure. A swab test is considered the gold standard for the diagnosis of COVID-19 despite the high number of false negatives.

[Imaging in diagnosis of acute pancreatitis and its complications].

Pancreatitis is a flogistic disease, caused by activation and digestion of pancreas by its enzymes. Diagnosis is based on integrated evaluation of clinical and laboratoristic data and morphological imaging. To evaluate the severity of pancreatitis there is a clinical classification in interstitial--mild pancreatitis and severe--necrotic one.

[Emergency Radiology layout].

The purpose of Radiologic Unit in Emergency is to reach diagnostic and therapeutic effectiveness in the best way and in less time possible. The Portable Ultrasound Device is an instrument necessary in Emergency Room and in ambulance/helicopter to evaluate the evidence of endoperitoneal bleeding. The CT is the radiologic methodic more fast that permits a complete evaluation of all body segments in traumatized patient in the famous "golden hour" after the trauma, therefore it would be placed in Emergency Area.

[The radiation dose problem in computed tomography. Actual data and strategies for a corrected use of ionizing radiation in computed tomography].

New technologies in these years has taken to a spread and to a growth of the CT application with an increase of patients and population exposure. In clinical practice some technical devices can be used to reduce the exposure dose of multidetector CT that allows radiologist to answer the clinical question with less damage to the patient. The radiologist remains however the guarantor of the ionizing radiation exposition and he has to consider also the opportunity to use other methodics (MR, US) to answer some questions.
