The continuous infusions of MgSO(4) were safe at the studied doses and maintained serum magnesium (SrMg) and ionized magnesium levels similar to levels required to produce smooth muscle relaxation in other clinical settings. Further studies are needed to investigate the efficacy of high-dose continuous MgSO(4) infusion as an adjunctive treatment for severe asthma treatment and determine the SrMg level required to maintain airway smooth muscle relaxation.

Rasburicase is a recombinant urate oxidase enzyme indicated for tumor lysis syndrome (TLS), a potential life-threatening oncologic emergency that occurs most commonly during chemotherapy for hematological malignancies. As a result of the defects in the physiological antioxidant pathway, erythrocytes of patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency are not protected against the oxidating stress exerted by hydrogen peroxide generated with the administration of rasburicase. Therefore, rasburicase is contraindicated in patients with known G6PD deficiency and the manufacturer recommends screening all patients with high risk for G6PD deficiency before initiating rasburicase therapy. However, it is logistically difficult in clinical settings because of the high risk of morbidity and mortality associated with TLS if treatment is delayed and the long turnaround time of the G6PD deficiency screening. Therefore, administering rasburicase to patients developing TLS before confirming a patient's G6PD status is practically inevitable. Methemoglobinemia, and/or hemolysis, may result from the oxidative stress. Descriptions of the clinical course should it happen are limited in the literature. There are eight reported cases of rasburicase-related methemoglobinemia, with or without hemolytic anemia, in the literature of which five are pediatric patients. Six reports (including three pediatric patients) had detailed descriptions of the event and management. The recent reports of methemoglobinemia observed in patients with probable G6PD activity further complicated the picture. We are reporting a 16-year-old patient diagnosed with Burkitt's lymphoma who developed methemoglobinemia after receiving one dose of rasburicase. He was managed by transfusion and oxygen support. The patient recovered well and the observed methemoglobinemia was reversible.

OBJECTIVE To determine if the asthma clinical pathway implemented at Wolfson Children's Hospital reduces the length of hospital stay. To determine if pathway use affected the use of asthma education, the use of appropriate discharge medications based on asthma classification, and readmission rates. METHODS A list of patients aged 2 to 18 years discharged from Wolfson Children's Hospital between September 1, 2004 and August 31, 2006 with the diagnosis of asthma was generated. Medical records of eligible patients were reviewed for demographic information, asthma pathway use, duration of hospital stay in days, readmission rates, receipt of asthma education, and medications prescribed upon discharge. Patients placed on the asthma clinical pathway were compared to a control group with asthma who were matched based on age and discharge date. Length of stay was averaged for each group. Asthma education, discharge medications, and readmission rates were compared between the two groups. RESULTS Forty-three patients placed on the asthma clinical pathway were compared to a 43 patients in the control group that were matched for age and discharge date. Use of the asthma clinical pathway reduced hospital stay by 0.372 days (P = .0373). Receipt of asthma education (P = .3864), the use of appropriate drug therapy prescribed upon discharge (P = .1398), and readmission rates (P = .5486) were unaffected by pathway use. CONCLUSIONS The asthma clinical pathway used at Wolfson Children's Hospital reduces length of hospital stay, but has no bearing on receipt of asthma education, use of appropriate drug therapy upon discharge, or readmission rates.

Vancomycin is a glycopeptide antibiotic that is used by the enteral route for the treatment of Clostridium difficile infections and is not thought to be absorbed into the systemic circulation. We report on a 2-year-old, 12.5-kg patient with confirmed C difficile colitis and renal insufficiency that was treated with 125 mg of enteral vancomycin (10 mg/kg); the patient developed measurable systemic concentrations as high as 17.8 mg/L. However, as the patient's colitis began to improve, the serial vancomycin concentrations reflected little to no continued absorption of vancomycin. A review of the literature regarding this rare phenomenon is discussed.

In this chapter, Edwards explores the meaning of Drake’s subtly revolutionary inscription and interprets it as an example of double-consciousness and alienation. Although some have interpreted Dave’s couplet as a straightforward celebration of the holiday, Edwards critiques this view, finding evidence of a “countervailing assertion of Dave the Potter’s black consciousness” in the inscription. The allusion to drums conflates war and nationalistic celebration with a tool often noted by paranoid plantation owners for being a tool of slave communication. The couplet thus hints at a “radical directive” to rebel. Edwards concludes by considering a variety of other meanings circulating around Dave’s inscription.
