Recently, plasmonic copper sulfide (Cu2-xS) nanocrystals (NCs) have attracted much attention as materials for photothermal therapy (PTT). Previous reports have correlated photoinduced cell death to the photothermal heat mechanism of these NCs, and no evidence of their photodynamic properties has been reported yet. Herein we have prepared physiologically(More)
Child passenger safety restraint laws have reduced the number of children killed or injured in motor vehicle accidents in the past few years. However, the increased used of child safety seats has brought with it an increase in the misuse of these devices. High cervical spine injuries sustained by five children less than 2 years of age while in(More)
To define a subset of injured children for whom emergency cervical spine radiography may be unnecessary, we performed a retrospective chart and radiologic review. Two entry methods were used: All injured children, from birth through 16 years, who had received cervical spine radiographs at The Children's Memorial Hospital from September 1983, to September(More)
The ideal treatment of children with head trauma would include prevention of posttraumatic seizures. Ninety-two of 937 children with head injuries (9.8%) experienced posttraumatic seizures. In 94.5% of these patients (87 of 92), seizures developed within the first 24 hours after injury. Three children convulsed between 24 hours and 7 days, but only 2(More)
Injuries resulting from falls from heights still constitute a significant portion of urban trauma. At this pediatric trauma center, 70 children were admitted from 1985 to 1988 after sustaining a fall of 10 feet or greater or at least one story. The mean patient age was 5 years and 68% of the patients were boys. Seventy-eight percent of falls occurred from 2(More)
A retrospective analysis of medical and financial records of trauma patients admitted over a 4-year period was undertaken to determine the impact of level 1 pediatric trauma center designation on demographics and financial reimbursement. Three hundred fifty-four patients were admitted from November 1, 1985, to October 31, 1986 (Prelevel 1 designation(More)
We evaluated the efficacy of rifampin in eradicating chronic pharyngeal carriage of group A streptococci. Carriers were defined as healthy children whose throat cultures showed persistence of group A streptococci 3 weeks after receiving benzathine penicillin G intramuscularly. Subsequent M and T typing of group A streptococcal isolates and limited serologic(More)
Nonoperative management of splenic and hepatic injuries in children is safe, and the majority of those with isolated injuries do not require blood transfusion. Thirty-seven children were treated for blunt splenic or hepatic trauma from November 1983 to September 1989. There was one death in a patient with a lethal head injury. No operations were performed(More)
Here we show that macrozwitterions of poly(ethyl 2-cyanoacrylate), commonly called Super Glue, can easily assemble into long and well defined fibers by electrospinning. The resulting fibrous networks are thermally treated on glass in order to create transparent coatings whose superficial morphology recalls the organization of the initial electrospun mats.(More)
RATIONALE Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is frequently used to analyze homo- and copolymers, i.e. for computing copolymer fingerprints. However, the oligomer abundances are influenced by mass discrimination, i.e. mass- and composition-dependent ionization. We have developed a computational method(More)
