The aim of this study was to determine the prevalence of vaginal Escherichia coli colonization and perianal carriage of Enterobacteriaceae resistant to third generation cephalosporins in pregnant women. Vaginal and perianal samples from 259 pregnant women were studied. Vaginal swabs were inoculated onto MacConkey agar plates and perianal swabs were(More)
Activating mutations of TSH-R have been described in toxic nodules and more recently in familial nonautoimmune thyrotoxicosis. This last entity is still confused with familial Graves' disease and the aim of this study is to define its phenotype. Based on 49 patients coming from our first family and on the 4 other kindreds secondarily described in the(More)
In Graves' disease, thyroid epithelial cells abnormally express HLA-DR Class II molecules in the vicinity of lymphocyte infiltrates, suggesting that lymphocyte proliferation is sustained by the appropriate presentation of antigenic material. The ability of thyroid epithelial cells to provide the necessary second signals has however not been documented. The(More)
Parathyroid hormone related protein (PTHrP) is the aetiological factor for the syndrome of humoral hypercalcemia of malignancy. The PTHrP gene encodes three isoforms of respectively 139, 141 and 173 amino acids with N-terminal homology to parathormone (PTH). PTHrP, which has a wide tissue distribution, appears to be a polyhormone with different physiologic(More)
The different degrees of lymphocytic infiltration observed in Graves' disease, Hashimoto's disease, and De Quervain thyroiditis suggest that the regulation of adhesion molecules expressed on endothelial cells could be different in these autoimmune disorders of the thyroid. Using immunohistological techniques, we observed that thyroid samples from patients(More)
Non-thyroid cancers rarely metastases to the thyroid gland. Metastases can be divided into those with clinical expression and those identified at necropsy. Symptom producing thyroid metastases are usually due to a primary renal cell cancer. We report two cases of thyroid metastasis of a clear cell renal carcinoma. In the first case, an 82-year-old woman(More)
Thyroid hormones may exert cardiovascular actions by direct effects on the myocardium, by interacting with the sympathetic nervous system and through alterations of the peripheral circulation. Then, thyroid hormones increase myocardial contractility and relaxation, sensitise the myocardium to sympathetic nervous system and decrease arterial resistance.(More)
Thyroid diseases are the most prevalent endocrine diseases. Faced with a thyroid enlargement or nodule, it is a challenge for the physician to determine with the best sensibility and specificity and the least cost which one are benign tumours and which are malignant neoplasms that need to be removed. The prevalence of solitary nodules is 1 to 5%. Only 2 to(More)
