Penetrating wounds and lacerations are frequent pathologies treated in the emergency room. The management of hand trauma represents a large part of the work in any surgical practice. Although X-rays are routinely taken, numerous foreign bodies remain undetected, and the wounds are just locally debrided and the lacerations sutured. Unfortunately, as not all foreign bodies are radio-opaque, the radiography results may appear normal, but the patient fails to recover. Patients complaining of persistent wound tenderness were sent for ultrasound investigations, and foreign bodies were detected. Had ultrasonography been carried out initially in the emergency room, the correct diagnosis would have been made, and the sonographic equipment could have helped to guide the physician in his attempt to remove the foreign body. Usually, in response to continued pain, an ultrasound investigation is ordered, and the pathology becomes apparent. A number of examples are briefly described in order to highlight the present inadequacies. It is suggested that hospital administrators consider the need to provide ultrasonographic services as an integral facility of the emergency room.

Cytomegalovirus is the most common cause of congenital viral infection. In utero infection is usually suspected in patients with growth-retarded fetuses or when maternal illness precipitates serological investigations. A case is presented where routine ultrasound examination at 30 weeks' gestation in an asymptomatic patient demonstrated mild fetal ventriculomegaly. Transvaginal ultrasound enabled the visualization of intraventricular adhesions and small periventricular cysts. The suspected diagnosis of in utero cytomegalovirus infection was confirmed by the presence of IgM antibodies in fetal blood and subsequently by isolation of the virus from the infant's urine. The presence of mild fetal ventriculomegaly should prompt transvaginal brain imaging.
