Case ReportsLow oxygen saturation by pulse oximetry may be associated with a low oxygen affinity hemoglobin variant, hemoglobin Titusville.
The authors describe a 10-year-old Caucasian boy who presented with abnormally low oxygen saturation values on pulse oximetry after a routine tonsillectomy. He was asymptomatic and there was no personal or family history of respiratory, cardiac, or hematologic disorders. ⋯ Hemoglobinopathies remain highly prevalent worldwide, with more than 65 low oxygen affinity hemoglobin variants identified to date. Early recognition of abnormal hemoglobin variants in asymptomatic patients may avoid extensive, unnecessary medical investigations.

Comparative StudyLow incidence of ototoxicity with continuous infusion of cisplatin in the treatment of pediatric germ cell tumors.
Cisplatin is an important chemotherapeutic agent in the treatment of many pediatric malignancies, but its use is limited in part by ototoxicity. The authors' institution has been administering standard-dose cisplatin by continuous infusion rather than bolus administration in germ cell tumors. The authors retrospectively reviewed 39 patients with germ cell tumors requiring chemotherapy over the past 20 years and recorded data including demographics, cumulative cisplatin dose, degree of ototoxicity (by the Brock grading system), and disease outcome. ⋯ This patient received a total cumulative dose of 500 mg/m of cisplatin. Eighty-two percent of children achieved clinical remission of their disease. The authors conclude that continuous administration of cisplatin is associated with minimal ototoxicity while maintaining good tumoricidal efficacy, and further studies using this regimen are warranted.
