Rewarming Young Children After Drowning-Associated Hypothermia and Out-of-Hospital Cardiac Arrest: Analysis Using the CAse REport Guideline.

Objectives: Extracorporeal membrane oxygenation (ECMO) is recommended in adults with drowning-associated hypothermia and out-of-hospital cardiac arrest (OHCA). Our experience of managing a drowned 2-year-old girl with hypothermia (23°C) and cardiac arrest (58 min) prompted this summary using the CAse REport (CARE) guideline to address the question of optimal rewarming procedure in such patients.

Design/patients: Following the CARE guideline, we identified 24 reports in the "PubMed database" describing children less than or equal to 6 years old with a temperature less than or equal to 28°C who had been rewarmed using conventional intensive care ± ECMO.

Life-Threatening Accidental Intravenous Epinephrine Overdose in a 12-Year-Old Boy.

Reports on accidental intravenous epinephrine overdose in children are extremely rare, although medication errors in the management of pediatric anaphylaxis seem to be frequent. We report a case of a 12-year-old boy presenting with a long-lasting skin rash and dyspnea who was incorrectly diagnosed with early anaphylactic shock and was treated with 10-fold the recommended dose administered by the wrong route (intravenous instead of intramuscular). He reacted with acute loss of consciousness and acute cardiorespiratory failure due to arterial hypotension, ischemic heart failure, and severe pulmonary edema.

An Fc-optimized NKG2D-immunoglobulin G fusion protein for induction of natural killer cell reactivity against leukemia.

Recruitment of Fc-receptor-bearing effector cells, such as natural killer (NK) cells, is a feature critical for the therapeutic success of antitumor antibodies and can be improved by the modifications of an antibody's Fc part. The various ligands of the activating immunoreceptor NKG2D, NKG2DL) are selectively expressed on malignant cells including leukemia. We here took advantage of the tumor-associated expression of NKG2DL for targeting leukemic cells by NKG2D-immunoglobulin G (IgG)1 fusion proteins containing modified Fc parts.

Impaired tumor rejection by memory CD8 T cells in mice with NKG2D dysfunction.

Cytotoxic T cells are important effectors for robust antitumor immune responses. However, tumor-infiltrating CD8 T cells are often functionally impaired. Insufficient antitumor activity of CD8 T cells can be due to a lack of costimulatory signals.
