Randomized Controlled Trial Comparative Study
Single daily dosing ceftriaxone and metronidazole vs standard triple antibiotic regimen for perforated appendicitis in children: a prospective randomized trial.
Appendicitis is the most common emergency condition in children. Historically, a 3-drug regimen consisting of ampicillin, gentamicin, and clindamycin (AGC) has been used postoperatively for perforated appendicitis. A retrospective review at our institution has found single day dosing of ceftriaxone and metronidazole (CM) to be a more simple and cost-effective antibiotic strategy. Therefore, we performed a prospective, randomized trial to compare efficacy and cost-effectiveness of these 2 regimens. ⋯ Once daily dosing with the 2-drug regimen (CM) offers a more efficient, cost-effective antibiotic management in children with perforated appendicitis without compromising infection control when compared to a traditional 3-drug regimen.

Given the perceived technical demands of laparoscopic appendectomy and the expected postoperative morbidity in patients with a well-defined abscess, initial percutaneous drainage has become an attractive option in this patient population. This strategy allows for a laparoscopic appendectomy to be performed in an elective manner at the convenience of the surgeon. However, the medical burden on the patient and on the quality of patient outcomes has not been described in the literature. Therefore, we audited our experience with initial percutaneous drainage followed by laparoscopic interval appendectomy to evaluate the need for a prospective trial. ⋯ The use of initial percutaneous aspiration/drainage of periappendiceal abscess followed by interval appendectomy is an effective approach. However, this management poses complication risks and uses considerable resources. Therefore, this strategy should be compared with early operation in a prospective trial.

Comparative Study
Laser microdissection allows detection of abnormal gene expression in cystic adenomatoid malformation of the lung.
Congenital cystic adenomatoid malformation (CCAM) of the lung may result from a localized aberrant epithelial-mesenchymal interaction during lung development. We used laser microdissection (LMD) to isolate the epithelium and mesenchyme of CCAM, and studied candidate gene expression in these pure cell populations. ⋯ LMD may be used to overcome the limitations of tissue heterogeneity in the study of CCAM. Abnormal growth factor expression may play a role in the etiology of this lesion.

Blunt trauma is the leading cause of pediatric injury, but pediatric aortic injuries are rare. We undertook this study to investigate the demographics, treatment, and outcomes of children with blunt aortic injuries and report our experience over a 10-year period. ⋯ Blunt aortic injury in children is uncommon and is primarily associated with motor vehicle crashes. Injuries to the abdominal aorta were seen with restrained children vs those to the thoracic aorta that were seen in children who were unrestrained.

Case Reports
Combined endovascular and surgical recanalization after central venous catheter-related obstructions.
Central venous occlusion in children is a challenging problem that can occur after a central venous catheter insertion. Long-term catheter-related complications include sepsis and venous thrombosis with consequent loss of central access. ⋯ The patients' survival was dependent on the restoration of central venous access until the planned intestinal transplantation could be performed. Retrograde recanalization of the superior vena cava was successfully achieved using a pathway created under general anesthesia from the femoral vein to, respectively, the right thyroid vein and the right subclavian vein.
