Wandering spleen is an uncommon clinical entity, which rarely affects children and adolescents. It is usually described in adults, especially women of childbearing age. Discussion in the literature has been limited to case reports and small case series. Here the authors present 2 children and 1 adolescent that presented to the authors institution over a(More)
Widespread use of extracorporeal membrane oxygenation (ECMO) has allowed an increasing number of infants with total agenesis of the diaphragm to survive. Polytetrafluoroethylene (PTFE) is the most widely used material for reconstruction. However, recurrent hernia is a growing problem; PTFE also does not grow with the patient. This study evaluated different(More)
BACKGROUND Laparoscopic surgery has reduced the length of hospital stay for common operations like cholecystectomy, gastric fundoplication, and appendectomy. We have noticed a reduction in length of hospital stay for children undergoing laparoscopic appendectomy. We, therefore, looked at our data to assess whether laparoscopic appendectomy in children could(More)
The aim of the study was to evaluate the clinical success rate of 73 patients with ventilator-associated pneumonia (VAP) caused by multidrug-resistant (MDR)-Acinetobacter spp. treated with tigecycline in seven intensive Care Units in Argentina and to determine which predictor variables were significant in this context. Clinical success in our patients was(More)
Pyomyositis is most often associated with Staphylococcus aureus infections after trauma. We describe an unusual presentation of pyomyositis of the chest wall secondary to group A betahemolytic streptococcus infection in a 15-month-old child with acute abdominal symptoms. In addition, the patient had no history or evidence of trauma to the affected area.(More)
Necrotizing enterocolitis (NEC) is a serious condition affecting predominantly the premature infant. The purpose of this study is to report a multicenter experience of complications in 252 infants requiring surgical therapy for NEC. Data from eight institutions for the years 1980 through 1990 were collected and analyzed for infants undergoing surgical(More)
Reports of nodular fasciitis among adults are common; however, this condition is relatively rare in the pediatric population. Its clinical and histologic characteristics are similar to malignancies such as sarcoma; thus, it is prudent for the clinician caring for children and adolescents to be aware of the possibility of its occurrence. Nodular fasciitis is(More)
Traumatic fractures of the adult pelvic area have high rates of associated injuries and hemorrhagic complications resulting in significant morbidity and mortality. We studied whether or not the plain roentgenographic identification of other fractures is a reliable marker of increased morbidity and mortality in children with pelvic fractures. The records of(More)
The authors reviewed the Extracorporeal Life Support Organization (ELSO) data base of all neonates placed on extracorporeal membrane oxygenation for whom CDH was diagnosed between January 1989 and December 1991. For 483 neonates, there were complete data concerning timing of the hernia repair in relation to ECMO. The overall incidence of hemorrhage was 43%(More)
Intravenous lipid emulsions are an important component of parenteral nutrition. Despite their benefits, lipid emulsions have been associated with higher rates of bacteremia in neonates. Therefore we investigated the effect of lipid emulsions on the inflammatory response by examining their effect on in vitro macrophage tumor necrosis factor (TNF) production(More)
