Laparoscopic total colectomy with ileo-rectal anastomosis for polyposis and ulcerative colitis. Eur Surg Res 2009;43:104
No full textIntroduction: Since the introduction of laparoscopic colorectal surgery, several studies have demonstrated the advantages of mini-invasive segmental colon resections in the treatment of benign and malignant diseases. On the contrary the use of laparoscopy for total colectomy and proctocolectomy is not worldwide accepted first of all because of the technically challenging nature of these procedures. The aim of this report is to show the feasibility and safety of straight laparoscopic total colectomy (LTC) for polyposis (P) and ulcerative colitis (UC).Material and methods: Between January 2006 and June 2007 in our Institution 5 patients underwent to LTC with ileorectal anastomosis plus temporary loop ileostomy for P ( 2 cases) and UC (3 cases). Results: The mean age was 69.2 yrs (62-77) and in all cases the preoperative endoscopy showed the distal rectum almost without signs of disease. Mean operative time was 320 minutes and the estimated mean blood loss was 250 cc. No transfusions were necessary. No conversions occurred. The mean surgical specimen length was 100 cm. and in all acses the margins of resection were disease free. Considering the postoperative course, no morbidity and mortality occurred. The mean hospital stay was 8 days. The temporary ileostomy was suppressed in all patients within three months since the procedure. Conclusions: The analysis of our data highlights that LTC is effective and feasible even if the use of this procedure, because of its complexity, has to be reserved to well-trained laparoscopic surgeons

Incidental thyroid carcinoma (ITC): a retrospective study in a series of 737 patients treated for benign disease
No full textAim: aim of the study is to evaluate correlations between incidental thyroid carcinoma (ITC) and benign thyroid pathologies (BTP), to determine the most represented histotype and to point out the total thyroidectomy’s possible advantages in terms of radicality, follow-up management and incidence of complications.Materials and Methods: during 10 years, 739 patients underwent thyroid surgery for BTP. Fine needle biopsy (FNAB) was negative in all cases; 503 total thyroidectomies(TT), 5 subtotal thyroidectomies(ST) and 231 emithyroidectomies(ET) were performed.Results: the specimens pathological examination revealed the presence of a ITC in 82 patients (11,1%); the prevalent histotype was the papillary one with a less than 1cm diameter in almost the totality of cases but with nodes metastasis in the 3,6% of cases. Complications were detected in 117 patients with a morbidity rate of 15,8%. Discussion: in our study the ITC prevalence was of 11,1% similar to literature with a higher incidence in patients affected by multinodular than uninodular goiter. No statistical significant differences were found between euthyroid and toxic pathologies. In our series hyperthyroidism doesn’t seem to hold a protective role towards the ITC onset. Conclusions: The ITC incidence is relevant; the prevalent histotype is papillary and nodes metastasis are present even if in a low percentage of cases. Besides, the complications of TT are similar to conservative procedures. The recurrence of goiter and ITC require a second surgical procedure, with a higher risk of complications. So we can claim that the standard surgical treatment of bilateral PBT would be represented by TT
Surgical treatment of splenic hydatidosis: Report of a case
No full textHydatid disease is a zoonitic infection caused by Echinococcus granulosus and rarely by multilocularis, that affects predominantly liver, to a lesser extent lung and occasionally other organs. This paper discusses a case study conducted at our Institute to evaluate the surgical management of splenic hydatidosis, and to illustrate the utility of a range of new techniques.
Splenic involvement alone is a rare event, even in endemic countries; many patients have no symptoms and its diagnosis can be either made fortuitously during diagnostic procedures such as chest or abdomen X-ray, or based on the appearance of those local symptoms caused by the pressure of growing cyst.
The treatment of hydatidosis traditionally consists of surgery, either conservative or radical, along with a perioperative course of antielmintic medications.
A number of therapeutic options for splenic localization exist, including conservative treatments such as Percutaneous Aspiration, Injection and Reaspiration (PAIR), cyst enucleation and partial splenectomy; and radical interventions such as total splenectomy.
The splenectomy remains today, as it was in the past, the treatment of choice for the radical treatment of the disease under consideration because of its associated rates of low mortality, low relapse and low hemorrhagic complications. The laparoscopic approach has to be reserved for well-selected cases: small cysts without adhesion to others organs

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
