Hemobilia and Melena After Liver Biopsy: A Case Report and Review of Literature.

Liver biopsy is the gold standard for assessment of hepatic fibrosis although it is associated with many complications. We reported a 28-year-old chronic HCV patient who developed gall bladder hematoma with hemobilia and melena after liver biopsy. The hematoma resolved with conservative management.

Microdosimetry of alpha particles for simple and 3D voxelised geometries using MCNPX and Geant4 Monte Carlo codes.

Microdosimetry using Monte Carlo simulation is a suitable technique to describe the stochastic nature of energy deposition by alpha particle at cellular level. Because of its short range, the energy imparted by this particle to the targets is highly non-uniform. Thus, to achieve accurate dosimetric results, the modelling of the geometry should be as realistic as possible.

[Thyroid cancer after Chernobyl: is iodine 131 the only culprit ? Impact on clinical practice].

The large increase in the incidence of thyroid cancer among children who were mainly less than five years old at the time of the Chernobyl accident is still a major preoccupation for endocrinologists and nuclear physicians. Epidemiological studies have focused solely on iodine 131. However, past knowledge on thyroid irradiation (medical use of iodine 131, radioactive fallout on Marshall islands and the Nevada, and Hanford site releases) as well as number of recent works (about low-dose irradiation), raise question on the role of other factors.

Kinetics of intracolloidal iodine in thyroid of iodine-deficient or equilibrated newborn rats. Direct imaging using secondary ion mass spectrometry.

The most significant impact of the Chernobyl accident is the increased incidence of thyroid cancers among children. In order to accurately estimate the radiation dose provided by radioiodines, it is important to examine how the distribution of newly incorporated iodine varies with time and if this distribution varies according to the iodine status. The kinetic distribution of intra colloidal newly organified iodine in the rat immature thyroid was recorded and analysed using the ionic nanoprobe NanoSims50.

[Kinetics of intracolloidal iodine within the thyroid of newborn rats. Direct imagery using secondary ion mass spectrometry].

The spatiotemporal distribution of cellular uptake site of radiotoxics is essential data for microdosimetric studies. As early as 1950, the heterogeneity of iodine incorporation within the thyroid has been shown using autoradiography. The objective of this study is to describe the kinetic cellular distribution of newly organified iodine in the thyroid of newborn rats using secondary ion mass microscopy (NanoSIMS50).
