Tissue quantification of radioiodine thyroid uptake in humans by an isotopic imaging technique on slides.

Background: Thyroid metabolism involves iodine, which allows us to use radioactive iodine for diagnostic and therapy purposes. The efficiency of radioiodine therapy depends on several parameters; the ability of thyroid tissue to uptake radioactive iodine is one of them.

Objective: The objective of this work is to quantify the radioactive iodine uptake on thyroid tissue.

[The fracture risk assessment tool (FRAXTM), where are we in Tunisia?].

Background: The fracture risk assessment tool (FRAXTM), published in February 2008, is developed based on the use of clinical risk factors with or without bone mineral density tests.

Aim: To calculate the FRAX tool in a cohort of Tunisian patients in whom bone mineral density (BMD) was assessed by dual X ray absorptiometry (DXA); to correlate this score to osteoporotic fracture and to BMD assessment and to propose a threshold for therapeutic intervention.

Methods: In a cross sectional study of 582 patients older than 40 years, in whom a BMD measurement by DXA has been performed between January 2006 and December 2009, clinical risk factor for osteoporotic fracture and the occurrence of a prior fragility fracture were assessed.

Captopril renography as a prognostic factor in obstructive hydronephrosis with preserved renal function.

Hydronephrotic kidney with a differential renal function greater than 55% is defined as supranormal. The signification of this finding remains controversial. In this article, the authors reported a case of supranormal function in obstructive hydronephrosis.
