Correlation between surgical intervention, adjuvant therapy, and long-term survival in patients operated on for breast neoplasia
No full textBrest cancer is the most frequentl cancer among female sexabove all in rich countries where it occurrs ten times more than the others . The most incidence of breast cancer is in female over 45 years and over 70 years with a plateau during menopause.though a random and retrospective sthudy among all an female patients who had surgery for breast cancer in the last ten years we have related the kind of surgical treatment to overal survival to the therapies, and to any possible local recurrence od f disease, We analized 270 femolesurgical treatment used the simple quadrantectomy up to radical mastectomy. With the association linfoadenectomy survival was of 82,2%
Role of Virtual Reality Simulators in the certification of bariatric surgeons
No full textAIMS: Several studies showed construct validity of virtual laparoscopic simulators for basic laparoscopic skills, however it is not yet clear whether the simulators can identify the actual experience of surgeons in more complex procedures such as laparoscopic Roux-en-Y gastric bypass. Our study tested the ability of the Lap Mentor simulator (SimbionixTM) to recognize the experience in advanced laparoscopic procedures assessing its role in the certification of bariatric surgeons.
METHODS: 30 surgeons were divided into two groups according to their experience in laparoscopic and bariatric surgery: General group included 15 general surgeons performing between 75 and 100 non bariatric laparoscopic procedures; Bariatric group included 15 bariatric surgeons performing between 50 and 100 laparoscopic bariatric procedures. Participants were tested on the laparoscopic simulator in one basic task (Task 1: eye-hand coordination) and in two tasks of the gastric bypass module (Task 2: creation of the gastric pouch, Task 3: gastro-jejunal anastomosis).
RESULTS: Comparing the groups, no significant differences were found in task 1 confirming the homogeneity of the two groups for basic laparoscopic skills. Analyzing the results from the gastric bypass module (bariatric vs. general), in task 2, significant differences (p < 0.05) were found in the median volume of the gastric pouch (22 vs. 48 cm3), in the percentage of fundus included in the pouch (8.8 vs. 30.1 %), in the complete dissection at the angle of His (14 vs. 4), and in safety parameters. In task 3, significant differences were found in the size and position of enterotomies.
CONCLUSIONS: Lap MentorTM simulator is able to recognize specific skills of bariatric surgeons also in technical details that affect long-term results of the procedure such as dissection at the angle of His and gastric pouch volume. Furthermore, the possibility of analyzing in details the performance can help define skills where the surgeon is more lacking. These findings suggest a potential role in tailoring the training to maximize improvement. The Lap Mentor may be proposed as a certification tool for bariatric surgeons
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

No full textRetroperitoneal fibrosis (RPF), also known as Ormond's disease, is a rare fibroinflammatory disease with uncertain etiology. RPF is characterized by the presence of a particular retroperitoneal fibrotic tissue which is white, woody and involving retroperitoneal structures such as the great vessels, ureters and psoas muscle. The main complication of RPF is the obstruction of local structures such as the ureters due to the fibrosis and the treatment of this aspect represents the main challenge for this pathology. RPF medical treatment consists of corticosteroids or/and immunosuppressive therapy. We report a case of a patient affected by idiopathic RPF treated with low-dose methotrexate (MTX) and 6-methylprednisolone (6-MP) for two years, describing and confirming the effectiveness and safety of a long-term low-dose MTX and 6-MP treatment associated to ureteral Double-J stenting avoiding more invasive surgical approaches
