[Effect of gender and obesity on postprandial lipemia in non-diabetic normolipidemic subjects and subjects with familial combined hyperlipidemia]. / Efecto del género y de la obesidad en la lipemia posprandial en sujetos sanos normolipidémicos no diabéticos y sujetos con hiperlipemia familiar combinada.

INTRODUCTION: A new method based on self-measurement of diurnal capillary triglycerides (TG) facilitates the study of postprandial lipemia (PL). The objectives of our study are: to evaluate the effect of gender and obesity on PL measured by self-determination of diurnal capillary TG with Accutrend GCT in normolipidemic non-diabetic subjects and subjects with familial combined hyperlipidemia (FCH). MATERIAL AND METHODS: We studied 23 FCH subjects (10 males) and 45 normolipidemic non-diabetic subjects (29 males). All subjects self-determine 3 diurnal capillary TG profiles during a week. RESULTS: In normolipidemic non diabetic subjects significantly higher diurnal TG profiles and area under the curve of TG (AUCTGc) (25.25 +/-9.09 vs 19.71 +/- 6.16 mmolh/l) were found in males compared to females. In FCH subjects these differences were not found and the AUCTGc correlated with BMI (r = 0.510, p < 0.05) and waist circumference (r = 0.453, p < 0.05). Obese subjects (BMI >or= 27 kg/m2) showed diurnal TG profiles and AUCTGc significantly higher than the non-obese. DISCUSSION: Normolipidemic non diabetic females showed a lower PL compared to males, probably due to the effect of estrogens in PL metabolism. Obesity negatively influences PL in normolipidemic non diabetic subjects and subjects with FCH.

Adrenocortical scintigraphy with 131I-6-beta-iodomethyl-norcholesterol (NP 59) in bilateral adrenocortical carcinoma.

A case of a 49-year-old man suffering from bilateral adrenocortical carcinoma with local and secondary rapid progression is reported. The results of adrenocortical scintigraphy (NP 59) and histological findings allowed the diagnosis. This case report and a literature review showed the importance of using adrenocortical scintigraphy as a complementary imaging procedure of CT or MR images.
