Comparative Study
Minimal pelvic fluid in blunt abdominal trauma in children: the significance of this sonographic finding.
The aim of this study was to evaluate the significance of the ultrasonographic finding of pelvic fluid after blunt abdominal trauma in children as a predictor of an abdominal organ injury. ⋯ A normal ultrasound examination or the presence of pelvic fluid are associated with a low probability of an organ injury. In the presence of peritoneal fluid outside the pelvis, the probability of an organ injury is very high.

Acetylcholinesterase (AChE) staining of rectal mucosal biopsy specimens is the most important and popular examination for making a definite diagnosis of Hirschsprung's disease. This examination often is performed for patients with constipation in the daily clinic. The results of this examination are reflected immediately in the treatment. However, the authors sometimes encountered difficult cases to diagnose, especially in neonates. Therefore, a retrospective investigation was conducted on the benefits and problems of AChE staining of rectal mucosal biopsy specimens in neonates. ⋯ The specificity of AChE staining was high (100%), but its sensitivity was slightly low (91%). Careful long-term follow-up is required for any cases diagnosed as normal. Mucosal biopsies should be repeated in cases of persistent clinical symptoms.

Pulmonary injury from mechanical ventilation has been attributed to application of excess alveolar pressure (barotrauma) or volume (volutrauma). The authors questioned whether partial liquid ventilation (gas ventilation of the perfluorocarbon filled lung, PLV) would reduce ventilator-induced lung injury. ⋯ (125)I-BSA leak produced during high-pressure or high-volume mechanical ventilation is reduced by partial liquid ventilation.

Acute appendicitis in children: the importance of family history.
Acute appendicitis is common, frequently atypical, challenging, and still associated with significant morbidity. Despite major technologic advances, appendicitis remains a primarily clinical diagnosis. Therefore, no relevant anamnestic information should be overlooked. Surprisingly, the relationship between heredity and appendicitis is seldom considered. Because of the potential clinical importance of the family history, the authors addressed this question prospectively over a 52-month period in a practice that includes the majority of pediatric patients with appendicitis in the region. ⋯ Heredity is a significant factor in pediatric patients who have appendicitis. Children who have appendicitis are twice as likely to have a positive family history than are those with right lower quadrant pain (but no appendicitis) and almost 3 times as likely to have a positive family history than are surgical controls (without abdominal pain). Because of its potential value in changing the threshold for intervention, a careful family history should be obtained for every child in whom acute appendicitis is suspected.
