Surgical complications in prophylactic central neck dissection: Preliminary findings from a retrospective cohort study

2014

Aim. Papillary thyroid carcinoma (PTC) is the most frequent thyroid malignancy with an overall ten-year survival more than 90%. Total thyroidectomy (TT) is considered the gold standard for PTC, but not all the endocrine surgeons agree on central neck dissection except in case of known metastases. Methods. We enrolled 158 patients, that underwent, between January 1990 and September 2012 total thyroidectomy±prophylactic CND for PTC. 59 Patients (group A) had a preoperative diagnosis of PTC; 99 (group B) had a diagnosis of benign disease. We focused on possible complications. Results. In group A we had 4 patients who blamed a definitive RLN palsy, only 1 patient in group B, with an OR=7.12. De…

Role of prophylactic central neck dissection in cN0-papillary thyroid carcinoma: Results from a high-prevalence area

2016

BACKGROUND: Prophylactic, compartment-oriented central neck dissection (CND) for cN0 papillary thyroid carcinoma (PTC) is not widely practiced. We examined our results with this surgical approach. METHODS: A cohort of 158 patients operated on for the classical variant of PTC at a follow-up of 1-22 years (mean: 6.6) were enrolled. The patients with a preoperative diagnosis of cN0 PTC (group A, 59 patients) underwent total thyroidectomy (TT) + CND. In the patients with incidental postoperative diagnosis of malignancy (group B, 99 patients) a TT alone was performed. RESULTS: Ninety-six T1, 36 T2, 26 T3/T4 PTC patients were enrolled. The overall biochemical/scintigraphic recurrence rate (15 pat…

LESIONI ORALI E CERVICALI ASSOCIATE A PAPILLOMA VIRUS UMANO

2009

The aim of this review is to carry out a quick excursus on the epidemiological and clinical aspect of oral and cervical lesions induced by human papillomavirus (HPV) infection and on the way this virus is transmitted. HPV infection is transmitted above all through vaginal or anal sexual relations with partners carrying the virus. Also other types of sexual relations, such as oral sex, can be a vehicle of transmission, though much more rarely. In literature there is not enough data proving that oral-genital contact can really be a vehicle of transmission for human papillomavirus. It can be concluded, therefore, that evidences in further studies with a large sample group of patients who pract…

OCT e GDx VCC : nelle patologie papillari non glaucomatose

2009

L'autore presenta una serie di patologie papillari non glaucomatose, evidenziando come una non corretta appropriatezza degli esami strumentali, possa indurre ad errori diagnostici. La diagnosi, quindi, non deve essere lasciata interamente alle macchine ma deve essere sempre guidata dall'uomo.

Wavelet Analysis Of Variance Risk Premium Spillovers

2013

In this paper we construct a variance risk premium spillover index among France, Germany, UK, Switzerland and the US. The variance risk premium is measured by the difference between the difference between the (square) of implied volatility and expected realized variance of the stock market for next month. We also construct a spillover index for the constituents of the variance risk premium. The series under investigation exhibit long memory properties. The construction of a total spillover indicator suggested by Diebold-Yilmaz (2009) would then rely on modeling a fractionally integrated Vector Autoregressive Model, which might be subject to errors in specifying the correct lag length and th…

Endogenous asymmetry and cooperative R&D in linear duopoly with spillovers

2009

In a standard model of R&D followed by linear Cournot competition, firm asymmetry is sustainable as equilibrium with non cooperative R&D if and only if the productivity of research is sufficiently large relative to the benefits of imitation. Increasing spillovers distribute R&D results among asymmetric competitors, causing price, firm asymmetry, and joint profit to reduce. With zero spillovers, a symmetric joint lab dominates asymmetric R&D competition in terms of social welfare and consumer surplus, but is sometimes dominated in terms of joint profit. Raising spillovers encourage symmetric collusion but makes the latter potentially harmful to consumers. (JEL : C72; L13; O32).
