OBJECTIVE: Pain in children is underestimated and undertreated in out-of-hospital emergency medicine. In this setting, caregivers need a reliable pain scale, but none has been validated. A single observational pain scale for all children younger than 8 years, EVENDOL, has been validated in emergency pediatric units. We study the feasibility of EVENDOL score in an out-of-hospital emergency setting. METHODS: This prospective multicenter study included all conscious children younger than 8 years transported by a mobile intensive care unit between October 2008 and May 2010...

Age estimation is an important procedure in forensic medicine and is carried out for a number of reasons. For living persons, age estimation is performed in order to assess whether a child has attained the age of criminal responsibility, in scenarios involving rape, kidnapping or marriage, in premature births, adoption procedures, illegal immigration, pediatric endocrine diseases and orthodontic malocclusion, as well as in circumstances in which the birth certificate is not available or the records are suspect...

REVIEW
A Dahlberg, F Milano
The utilization of cord blood as a source of stem cells for transplantation has decreased in recent years. Although cord blood transplantation (CBT) is an established practice for the treatment of adult and pediatric patients with hematological malignancies, the high acquisition cost of CB units along with high transplant-related mortality due to delayed hematopoietic recovery and immune reconstitution have contributed to the slowing in widespread adoption of CBT. Strategies aimed to enhance speed of engraftment and ongoing clinical trials are investigating ways to make CBT more widely available...

Childhood cancer survivors (CCS) are a fast growing population, but late adverse effects of cancer therapies are not rare. In CCS treated with cranial radiotherapy, growth hormone deficiency (GHD) is a well-known occurrence and the potential impact of GH replacement therapy on the global outcome of CCS is under continuous evaluation. In the present review, we discuss advantages and disadvantages of GH replacement therapy in survivors of pediatric malignancies, taking into consideration the different reasons for treating GHD during childhood or adult life...

New therapeutic approaches are needed to treat leukemia effectively. Dietary restriction regimens, including fasting, have been considered for the prevention and treatment of certain solid tumor types. However, whether and how dietary restriction affects hematopoietic malignancies is unknown. Here we report that fasting alone robustly inhibits the initiation and reverses the leukemic progression of both B cell and T cell acute lymphoblastic leukemia (B-ALL and T-ALL, respectively), but not acute myeloid leukemia (AML), in mouse models of these tumors...

The safe sedation of children for procedures requires a systematic approach that includes the following: no administration of sedating medication without the safety net of medical/dental supervision, careful presedation evaluation for underlying medical or surgical conditions that would place the child at increased risk from sedating medications, appropriate fasting for elective procedures and a balance between the depth of sedation and risk for those who are unable to fast because of the urgent nature of the procedure, a focused airway examination for large (kissing) tonsils or anatomic airway abnormalities that might increase thepotential for airway obstruction, a clear understanding of the medication's pharmacokinetic and pharmacodynamic effects and drug interactions, appropriate training and skills in airway management to allow rescue of the patient, age- and size-appropriate equipment for airway management and venous access, appropriate medications and reversal agents, sufficient numbers of staff to both carry out the procedure and monitor the patient, appropriate physiologic monitoring during and after the procedure, a properly equipped and staffed recovery area, recovery to the presedation level of consciousness before discharge from medical/dental supervision, and appropriate discharge instructions...
