ABSTRACT
Donor-acceptor cyclopropenes formed from enoldiazoketones undergo catalytic rearrangement to 5-aryl-2-siloxyfurans via a novel mechanism that involves a nucleophilic addition of the carbonyl oxygen to the rhodium-activated cyclopropene.
ABSTRACT
5-Acyl-5-phenyl-1,5-dihydro-4H-pyrazol-4-ones, accessible from arylpropargyl phenyldiazoacetates, are highly selective acyl transfer reagents for di- and polyamines, as well as aminoalcohols and aminothiols. As reagents with a carbon-based leaving group, they have been applied for benzoyl transfer with a broad selection of substrates containing aliphatic amino in combination with other competing nucleophilic functional groups. The substrate scope and levels of selectivity for direct benzoyl transfer exceed those of known benzoylating reagents. With exceptional selectivity for acylation between primary amines bound to primary and secondary carbons, these new reagents have been used in direct site-selective monobenzoylation of aminoglycoside antibiotics.
ABSTRACT
OBJECTIVES: The Accreditation Council for Graduate Medical Education requires training in patient safety and medical errors but does not provide specification for content or methods. Pediatric emergency medicine (EM) fellowship directors were surveyed to characterize current training of pediatric EM fellows in patient safety and to determine the need for additional training. METHODS: From June 2013 to August 2013, pediatric EM fellowship directors were surveyed via e-mail. RESULTS: Of the 71 eligible survey respondents, 57 (80.3%) completed surveys. A formal curriculum was present in 24.6% of programs, with a median of 6 hours (range = 1 to 18 hours) dedicated to the curriculum. One program evaluated the efficacy of the curriculum. Nearly 91% of respondents without formal programs identified lack of local faculty expertise or interest as the primary barrier to implementing patient safety curricula. Of programs without formal curricula, 93.6% included at least one component of patient safety training in their fellowship programs. The majority of respondents would implement a standardized patient safety curriculum for pediatric EM if one was available. CONCLUSIONS: Despite the importance of patient safety training and requirements to train pediatric EM fellows in patient safety and medical errors, there is a lack of formal curriculum and local faculty expertise. The majority of programs have introduced components of patient safety training and desire a standardized curriculum.

A limited number of publications have addressed the health care needs of Chinese American children of recently immigrated parents. We administered a Chinese-language survey to parents presenting to an urban pediatric emergency department (PED) in New York City and at community venues. The survey assessed demographics, access to health care, and utilization/expectations of the PED. Emergency Severity Index scores were recorded for emergency department patients. Three hundred fifteen families (54% in the PED) completed the survey. Of those completed in the PED, 79% sought emergency services because of pediatric referral or because their pediatrician's office was closed. Of our sickest patients with an Emergency Severity Index score of 3 or less, 28% of parents felt that the child was somewhat sick or not sick at all. Although the majority of our Chinese American families utilize the emergency department appropriately, 28% of the parents of our sickest patients did not appreciate the degree of illness of their children.

Out-of-hospital emergencies occur frequently, and laypersons are often the first to respond to these events. As an outreach to our local communities, we developed "Basic Emergency Interventions Everyone Should Know," a three-hour program addressing cardiopulmonary resuscitation and automated external defibrillator use, heart attack and stroke recognition and intervention, choking and bleeding interventions and infant and child safety. Each session lasted 45 minutes and was facilitated by volunteers from the emergency department staff. A self-administered 13-item questionnaire was completed by each participant before and after the program. A total of 183 participants completed the training and questionnaires. Average score pre-training was nine while the average score post-training was 12 out of a possible 13 (P< .0001). At the conclusion of the program 97% of participants felt the training was very valuable and 100% would recommend the program to other members of their community.
ABSTRACT
Hypokalemia is a frequent electrolyte abnormality that rarely requires more than oral supplementation to correct. We describe a case of profound hypokalemia and cardiac arrhythmia requiring unusually large amounts of "bolused" potassium to restore to normal sinus rhythm. Our patient presented with significant dehydration and electrolyte abnormalities after several days of emesis. Most alarming of these findings was a serum potassium level of 1.2 mEq/L. The electrocardiogram showed changes consistent with hypokalemia that rapidly degraded into pulseless ventricular tachycardia. Potassium chloride of 140 mEq was hand-pushed during the resuscitation with return of spontaneous rhythm. The patient was discharge 11 days later in his prearrest state.

BACKGROUND: Latinos are the fastest growing minority group in the United States with a significant percentage of this population having limited English proficiency. OBJECTIVE: To determine whether mode of interpretation influences satisfaction of limited English-proficient parents presenting to a tertiary care pediatric emergency department. DESIGN: One hundred eighty parents of patients presenting to a pediatric emergency department were surveyed after receiving services from one of the following interpreters: hospital-trained, ad hoc, or telephone. An English-proficient comparison group of 60 parents of any ethnicity was also surveyed (total N = 240). RESULTS: Parents were significantly more satisfied (P < 0.001) with hospital-trained interpreters. While no significant difference was found in overall visit satisfaction, there were significant differences in several other outcome variables. When hospital-trained interpreters were used, parents were significantly more satisfied (P < 0.001) with their physicians and nurses. With regard to the ability to communicate with pediatric emergency department personnel, parents using hospital-trained interpreters averaged significantly higher scores (P < 0.001) than the telephone group. Quality-of-care scores were significantly higher (P < 0.001) for parents assigned to hospital-trained interpreters than for the other forms of interpretation. English-proficient parents scored highest in the following categories: ability to communicate, quality of care, and overall visit satisfaction. Parents using hospital-trained interpreters scored higher than English-proficient parents when questioned about physician and nursing satisfaction. CONCLUSION: Hospital-trained interpreters are a valuable and needed resource to facilitate communication with limited English-proficient patients and families. Other interpretation services are useful but have limitations.

OBJECTIVE: To determine the utility of continuous noninvasive capnometry for monitoring pediatric patients with diabetic ketoacidosis as assessed by the agreement between end-tidal carbon dioxide (PetCO2) and PCO2 DESIGN: Clinical, prospective, observational study. SETTING: University affiliated children's hospital. INTERVENTIONS: Patients with diabetic ketoacidosis were monitored with an oral/nasal carbon dioxide (CO2) sampling cannula while in the emergency department. Laboratory studies were ordered per protocol. PetCO2 values were correlated with respiratory rate, PCO2, and pH. MEASUREMENTS AND MAIN RESULTS: One hundred twenty-one patients were monitored for 5.9 +/- 0.32 hrs. The average (mean +/- sd) initial values for pH were 7.08 +/- 0.18; respiratory rate, 35.1 +/- 9.1 breaths/min; PetCO2, 18.6 +/- 10.8 torr; and venous PCO2, 20.2 +/- 10.6 torr. At the conclusion of the observation period, averages were pH, 7.29 +/- 0.05; respiratory rate, 22.4 +/- 3.7 breaths/min; PetCO2, 35.3 +/- 5.8 torr; and venous PCO2, 36.8 +/- 5.3 torr. For all 592 observations, the correlations between PetCO2 and venous PCO2 (r =.92, p =.0001), PetCO2 and pH (r =.88, p =.0001), Petco2 and respiratory rate (r = -.79, p =.0001), and respiratory rate and pH (r = -.80, p =.0001) were statistically significant and the correlations with respiratory rate were inversely related to pH and PetCO2. The difference scores were not related to the average scores for initial readings (r = -.073, p =.43), final readings (r = -.124, p =.18), and overall readings (r =.057, p =.17). Limits of agreement between the two methods were established with PetCO2 lower than venous PCO2 with 95% limits of agreement 0.8 +/- 8.3 (2 sd) torr. CONCLUSIONS: PetCO2 monitoring of patients with diabetic ketoacidosis provides an accurate estimate of PCO2. Noninvasive PetCO2 sampling may be useful in patients with diabetic ketoacidosis to allow for continuous monitoring of patients.
