BACKGROUND Interleukin-6 (IL-6) exerts its actions through a cell-surface receptor system that consists of two transmembrane subunits: the IL-6 binding glycoprotein gp 80 (IL-6R) and the signal-transducing component (gp 130). Soluble forms of the IL-6R (sIL-6R) are generated by shedding of the membrane-associated proteins. The sIL-6R binds the ligand IL-6(More)
BACKGROUND We compared the oncologic effectiveness of open adrenalectomy and endoscopic adrenalectomy in the treatment of patients with localized adrenocortical carcinoma. METHODS One hundred fifty-six patients with localized adrenocortical carcinoma (stage I/II) who underwent R0 resection were included in an Italian multiinstitutional surgical survey.(More)
Optimal management of adrenocortical carcinoma (ACC) involves a detailed diagnostic workup, radical surgery, and appropriate adjuvant therapy. However, due to the rarity of this disease, adequate expertise is necessary to ensure optimal patient care. We evaluated if the experience of a treating center influences the outcome of ACC. Two hundred sixty-three(More)
BACKGROUND The acceptability of the classic laparoscopic technique in the treatment of acute appendicitis is slow, probably due to the higher costs of this method compared to the cheaper, efficacious, safe and rapid discharge associated with traditional surgery. METHODS In order to combine the advantages of the laparoscopic technique with those of(More)
BACKGROUND Primary aldosteronism (PA) is associated with an increase in left ventricular (LV) mass beyond the amount needed to compensate the hypertension-related workload. Available evidence suggests effectiveness of surgical treatment of PA in decreasing LV mass, whereas data on medical treatment are controversial. We have conducted a meta-analysis of(More)
Adrenocortical carcinoma (AC) is a rare tumor with poor prognosis. Twenty-two patients (14 F, 8 M; age 22 to 59 years; median, 43 years) with AC were evaluated prospectively in a single center: tumor stage was I–II in 12 cases and III–IV in 10. The overall survival in our cohort was 41.6 ± 42 months; 16 subjects are still alive. Curative surgery was(More)
Hürthle cell neoplasms (HNC) of the thyroid gland are uncommon, but potentially malignant lesions. Opinion is divided as to their most suitable surgical treatment. In the ten-year period between 1976 and 1986, 46 patients with Hürthle cell tumor underwent surgery in our Department. Preoperative diagnosis was made by fine needle biopsy. In all cases but six,(More)
We recently demonstrated in an immortalized thyroid cell line that integrin stimulation by fibronectin (FN) simultaneously activates two signaling pathways: Ras/Raf/MAPK kinase (Mek)/Erk and calcium Ca2+/calcium calmodulin-dependent kinase II (CaMKII). Both signals are necessary to stimulate Erk phosphorylation because CaMKII modulates Ras-induced Raf-1(More)
Medullary thyroid carcinomas (MTC) occur sporadically or as part of inherited multiple endocrine neoplasia (MEN) type 2 syndromes. To recognize misdiagnosed familial cases and to establish the frequency of somatic mutations, a series of 50 patients, clinically diagnosed with sporadic MTC, were analyzed for mutations in the RET proto-oncogene. The clinical(More)
