Abstract
Data on post-transplant iron overload (IO) are scarce in pediatrics. We conducted a prospective multicenter cohort study (Leucémie de l'Enfant et de l'Adolescent cohort) to determine the prevalence and risk factors of IO in 384 acute leukemia survivors transplanted during childhood. Prevalence of IO (ferritin level ⩾350 ng/mL) was 42.2% (95%CI 37.2-47.2%). Factors significantly associated with IO were: 1) in univariate analysis: older age at transplant (P<0.001), allogeneic versus autologous transplantation (P<0.001), radiation-based preparative regimen (P=0.035) and recent period of transplantation (P<0.001); 2) in multivariate analysis: older age at transplant in quartiles (Odds Ratio (OR)=7.64, 95% CI: 3.73-15.64 for age >12.7 years and OR=5.36, 95% CI: 2.63-10.95 for age from 8.2 to 12.7 years compared to age < 4.7 years), acute myeloid leukemia (OR=3.23, 95% CI: 1.47-7.13), allogeneic graft (OR=4.34, 95% CI: 2.07-9.12 for alternative donors and OR=2.53, 95% CI: 1.2-5.33 for siblings, compared to autologous graft) and radiation-based conditioning regimen (OR=2.45, 95% CI: 1.09-5.53). Graft-versus-host disease was an additional risk factor for allogeneic graft recipients. In conclusion, IO is a frequent complication in pediatric long-term survivors after transplantation for acute leukemia, more frequently observed in older children, those transplanted from alternative donors or with graft-versus-host disease.

Abstract
It is well known that so-called bullet-proof vests offer protection against a wide range of penetrating trauma, but their protection against blunt trauma is less well understood. Fast projectiles may result in hematomas and contusions behind the armour. We report a traffic accident involving a young soldier wearing a ballistic protection vest resulting in a right thoracoabdominal blunt trauma leading to a confined liver compression rupture. As nearly no skin marks were detectable, we point out that every emergency department surgeon should be very suspicious if a patient wore a ballistic vest at the time of the accident--there may be no skin marks despite severe intra-abdominal trauma. Our patient recovered following hypotensive ICU treatment, thrombocyte mobilization, and factor VIIa substitution.

Abstract
The National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) for seaweed was developed through an interlaboratory comparison with 24 participants from 16 countries. After evaluating different techniques to calculate certified values for the radionuclides, the median method was found to be the most representative technique. The certified values were provided for 13 radionuclides and information values were given for 15 more radionuclides. Results for the natural decay series showed disequilibrium in both the uranium and thorium series.

Abstract
Hepatocellular dysfunction and perturbed portal hemodynamics alter steroid metabolism. Men with liver disease have gynecomastia, although women similarly affected rarely show virilization. We report a 10-yr-old girl with portal hypertension and shunting associated with precocious puberty and ovarian hyperandrogenism. This was one of premature twin girls; neither had clitoromegaly or genital ambiguity. In one child, neonatal respiratory problems led to umbilical vein catheterization with subsequent development of portal hypertension. Pubic hair was first noted at age 6 yr, breasts at 7 yr, and severe acne and clitoromegaly at 10 yr. Baseline sex hormones were elevated: androstenedione (A), 413 ng/dL; testosterone (T), 226 ng/dL; and estradiol (E2), 160 pg/mL. Liver transaminases were within the normal range, however, the coagulation profile was mildly abnormal. Cosyntropin adrenal stimulation revealed no steroidogenic defect. Dexamethasone suppression reduced A and T slightly. LH-releasing hormone stimulation produced a pubertal rise in LH and FSH. Pelvic sonography showed a large right ovary with numerous follicles. Surgical exploration revealed symmetrically enlarged ovaries with dense capsules. Histology of ovarian wedge resections showed hyperthecosis; immunohistochemistry showed stromal cells expressing steroidogenic enzymes and proteins. One month postoperatively, A and T were unchanged from baseline, whereas E2 decreased to 56 pg/mL. A single dose of depot leuprolide acetate significantly reduced T. Subsequent treatment with oral contraceptives reduced T to 50 ng/dL, and cyclical menses occurred. We conclude that precocious puberty and ovarian hyperthecosis were induced in this young girl by elevated circulating levels of sex hormones, a consequence of portasystemic shunting and impaired hepatic steroid metabolism.

Abstract
Physical examination may be unreliable in the evaluation of children with blunt abdominal trauma particularly in those with associated major head injuries. In the absence of obvious clinical signs or physical findings of intraabdominal injury, the usefulness of abdominal computed tomography in children is controversial. To test the efficacy of CT scans, a 12-month prospective study of computed tomography for the initial assessment of children with blunt abdominal trauma and major head injuries was carried out. Of 320 pediatric trauma admissions to our regional trauma center, 65 consecutive patients with Glasgow Coma Scores less than ten were managed with sequential head and abdominal computed tomography in the emergency room for (1) closed head injury and (2) suspected abdominal trauma. Fifteen patients (23%) were found to have significant intraabdominal injury. Only two required operative intervention. No patients died as a result of the abdominal injuries. In children with significant head trauma and suspected abdominal trauma, combined head and abdominal CT proved to be reliable.
