Background: Measurements of TSH, free tetraiodothyronin (FT4) and triiodothyronin (FT3) are essential to achieve assessment of thyroid function. Luminescent Oxygen Channelling Immunoassays (LOCI) have recently been developed for the measurement of biomarkers of thyroid function. Such homogeneous immunoassays allow a faster delivery of the results. The aim of our study were therefore to determine the reference values for LOCI TSH, FT4 and FT<sub...

A 64-year-old Algerian woman was transferred to our institution with a pituitary tumor causing severe visual impairment. Magnetic resonance imaging (MRI) showed a T1-isointense, T2-hyperintense sellar mass measuring 48×35×30 mm, with homogenous enhancement after gadolinium injection (Figure 1). This mass extended to the suprasellar region, compressing the optic chiasma, and to both cavernous sinus, completely surrounding and narrowing carotid arteries. Ophthalmologic...
