    Notes: Abstract  This study evaluates the safety and role of laparoscopy in the diagnosis of blunt abdominal trauma in children. Laparoscopy was performed in five patients aged 3 to 13 years because of persistent abdominal pain after blunt trauma. A laparotomy was not indicated from the physical examination, laboratory data, or radiologic findings. With the patient under general anesthesia, a 10-mm trocar was inserted through the umbilical fossa and the intra-abdominal organs were observed for 10 – 60 min under an insufflation pressure of 10 – 12 mmHg. The patients remained hemodynamically stable without pneumothorax development. Three patients underwent laparatomies: one, who had blood in the omental sac, had a duodenal injury with hemorrhagic necrosis and underwent a resection; one with ascites and high amylase levels had an injury of the main pancreatic duct and underwent resection of the pancreatic tail; and one who had fresh blood in the upper abdomen and Douglas’ pouch had a splenic hemorrhage and underwent hemostasis. The other two had serous or serosanguinous ascites and recovered without surgery. In patient 1, the same amount of information might have been obtained from a barium study. In patient 2, the pancreatic transection might have been diagnosed from ascites shown on serial computed tomograms. Patient 3 might also have been treated successfully non-surgically. It hus appears that laparoscopy may be a safe diagnostic method for blunt abdominal trauma in children, however, this small series has yielded insufficient information to assess its usefulness in making the diagnosis and the decision for laparotomy. Further studies are required to ascertain whether it will make any significant difference in the form of management.

    Notes: Abstract Interactions between a pair of two-electron (singlet or triplet) systems undergoing abstraction, insertion, exchange and association reactions are treated on the basis of the quantum Heisenberg model. The local spin-permutation-symmetry properties of these reactions can well be visualized from the continuous or discontinuous variations of Penney's bond orders for the interacting electron pairs. In reactions where such a local permutation symmetry is not conserved, there is an apparent transition between two distinct valence-bond structures. It is shown that the concept of the local spin-permutation-symmetry conservation is useful for understanding the nature of the electron pairing requirement inherent in reactions of biradical species.
