A prospective nonrandomized study was made of 17 basketball players with fractures of the proximal third of the shaft of the fifth metatarsal. Eight had acute fractures, which were treated with a cast without weight-bearing, and the other nine had stress fractures for which percutaneous compression screwing was initially used. In the first group, union was obtained in four cases in an average of 9 weeks, with resumption of sport by 12 weeks. Three had a good outcome and the fourth was fair. The other four cases, which had not healed after 12 weeks of immobilization, were subsequently treated using compression screws. Resumption of sport was achieved 20-24 weeks after the fracture. Two of these had a good result; in the other two the results were fair. Of the nine patients with stress fractures in which a screw was inserted, all healed between 8 and 14 weeks and returned to sport within 7-12 weeks. Seven had a good result and the other two only fair. There was one intraoperative complication, but no postoperative complications, such as nonunion or refracture, were observed. Even if the non-operative treatment is able to provide a good result, immobilization without weight-bearing does not guarantee healing. In this series, percutaneous screw fixation was able to achieve successful healing in a short period of time. Thus, this procedure seems to be preferable for primary treatment of this lesion in athletes.

Congenital hepatic cyst is a rare and nonsymptomatic condition in infants and children. Its incidence is 2.5% in the postnatal life with a much lower incidence in the prenatal period. Incidental finding on antenatal imaging is the most common presentation. We present a case of a newborn in whom fetal ultrasound detected a cyst within the fetal liver. Postnatal imaging revealed a liver cyst in the right lobe of the liver, with no other intrahepatic structure affected. Liver function tests were abnormal, but the patient was asymptomatic. Posterior follow-up imaging showed a minor decrease in size. Management of congenital hepatic cyst is usually conservative, done with periodic ultrasound monitoring. However, surgical treatment is the mainstay of treatment when hydrops, progressive enlargement, hemorrhage, torsion, or compression of adjacent structures occurs. Malignant transformation can occur, but it is extremely rare. Partial or total removal of the cyst is the preferred treatment in neonates with a large lesion.

Desde su incorporación a la práctica odontológica la radiología digital ha experimentado un importante desarrollo. El continuo avance de las tecnologías en las que se sustenta ha dotado a estos sistemas de interesantes prestaciones que pueden facilitar el diagnóstico y manejo de imágenes radiográficas. Con estos avances la radiología digital ha despertado un interés creciente entre los profesionales de la odontología, especialmente durante los últimos años, en los que ha aumentado notoriamente tanto la cantidad de sistemas comercializados como el número de odontólogos que han decidido sustituir la radiología convencional por un sistema digital en sus clínicas. En esta revisión de la literatura se tratará de ofrecer una visión actualizada de los distintos sistemas disponibles en la actualidad, así como una comparativa entre ellos basada en estudios publicados recientemente.

A 231/7-week-old and 560-g-weighing premature male infant was evaluated on day of life 33 for increased frequency of bradycardias, bilious residual, and an increase in abdominal girth. Physical examination was notable for distended and mild tender abdomen. Investigations revealed pneumoperitoneum with dilated bowel loops and a normal acid–base balance. An urgent exploratory laparotomy demonstrated isolated jejunal perforation with an adhesive band extending from the omentum to the base of the mesentery. A segmental jejunal resection followed by an end-to-end anastomosis was performed. The diagnosis of intestinal perforation was inconsistent with focal spontaneous intestinal perforation and necrotizing enterocolitis. Decision to perform exploratory laparotomy led to diagnosis of congenital adhesion band, a rare clinical condition, and the patient had a favorable outcome. This premature infant made an excellent recovery and the upper gastrointestinal (GI) study demonstrated that the anastomotic site was intact. He is currently tolerating advancing enteral feeds.
