[About two cases of massive hypercholesterolemia]

Two patients presented massive hypercholesterolemia related to acquired disease, intrahepatic cholangitis with cholestasis in one and nephrotic syndrome in the second. Comparison of the lipoprotein patterns demonstrated distinctive pathophysiological processes different from those operating in primary causes of hypercholesterolemia.

[Unexpected occurence of hemoglobin Athens-Georgia]

The following report concerned a 47 year old Caucasian diabetic patient. Routine HPLC of HbA1c (Variant II Biorad Laboratories - hemoglobin A1c program) resulted only in the evidence of HbF (1%) and increase in HbA1c (10%). Considering the presence of HbF a standard agarose gel electrophoresis of patient's hemoglobin was performed and revealed the presence of Hb Athens-Georgia. Consequently the occurrence of HbF during determination of HbA1c by HPLC should lead to perform a standard hemoglobin electrophoresis in order to explore an hidden, unsuspected and clinically silent occurrence of rare Hb variant or additional unsuspected increase in HbA2.

[Refinement and study of the performance of a "Mycoplasma UG" kit for the research on urogenital Mycoplasmas]

The pathogenic role of genital Mycoplasmas is no more disputably. The diagnosis is based on the culture which may present some technical difficulties. The present study consist in a perfecting of a miniaturised system called "Mycoplasma UG" for the research, identification and titration of genital Mycoplasmas. The performance of the kit is studied with an important number of different types samples by comparison with the commercial kit "Mycoplasma Duo" and the classic reference method. The results obtained are satisfactory and constitute an important element in favour of a more advanced validation before the kit's trading.
