Histomorphological evaluation, cell proliferation and endothelial immunostaining in oral and maxillofacial myofibroblastic lesions.

2022

Myofibroblasts (MF) are mesenchymal cells with features of both fibroblasts and smooth muscle cells. Although these are usually reactive cells, they can lead to myofibroblastic tumors that may share clinical and histomorphological characteristics but with different prognosis. The aim of this study is to perform a histomorphological evaluation as well as to compare and evaluate two different cell proliferation immunomarkers and two endothelial markers in a group of oral and maxillofacial myofibroblastic lesions (MFL). Cross-sectional and retrospective study. Demographic, clinical, histomorphological and immunohistochemical characteristics of 39 cases of MFL were analyzed. Immunohistochemical…

The HERBA Study: A Retrospective Multi-Institutional Italian Study on Patients With Brain Metastases From HER2-Positive Breast Cancer

2019

There is no sufficient evidence to establish a standard of care for patients with brain metastases (BM) from HER2Data of 154 patients were retrospectively collected at 14 Italian institutions through a specifically designed database.Median overall survival (OS) was 24.5 months. Patients receiving surgery/stereotactic radiosurgery experienced longer OS compared to those receiving whole-brain radiotherapy or no treatment (33.5 vs. 11.4 months; hazard ratio = 0.34; 95% confidence interval, 0.22-0.52; P .001). Interestingly, whole-brain radiotherapy did not improve OS compared to no treatment (11.4 vs. 9.8 months; hazard ratio = 0.99; 95% confidence interval, 0.62-1.62; P = .99). HER2-targeted …

The Association of Appendectomy, Adhesions, Tubal Pathology, and Female Infertility.

2019

Background and Objectives: The aim of the study was to investigate a potential association between previous childhood appendectomy, tube pathology, and female infertility. Methods: We reviewed patients seeking care at the fertility clinic of our university medical center between 2006 and 2016. The history of previous appendectomy was extracted from hospital documentation and by telephone follow-up. Tubal patency was assessed by diagnostic laparoscopy and chromopertubation. Results: In our study cohort (N = 237), 24.9% (n = 59) had a history of previous appendectomy. Previous appendectomy, therefore, was about 3-fold more prevalent in women seeking fertility treatment than in the general pop…

Association between condylar asymmetry and temporo- mandibular disorders using 3D-CT

2011

Objectives: Using reconstructed three-dimensional computed tomography (3D-CT) models, the purpose of this study was to analyze and compare mandibular condyle morphology in patients with and without temporomandibular disorder (TMD). Study Design: Thirty-two patients were divided into two groups: the first comprised those with TMD (n=18), and the second those who did not have TMD (n=14). A CT of each patient was obtained and reconstructed as a 3D model. The 64 resulting 3D condylar models were evaluated for possible TMD-associated length, width and height asymmetries of the condylar process. Descriptive statistics were used to assess the results and student’s t tests applied to compare the tw…

Prognostic Implications of the Standardized Study of Resection Margins in Pancreatic Cancers

2013

Abstract Introduction Involvement of surgical resection margins is a fundamental prognostic factor in pancreatic oncological surgery. However, there is a lack of standardized histopathology definition. The aims of this study are to investigate the real rate of R1 resections when surgical specimens are evaluated according to a standardized protocol and to study its survival implications. Patients and methods One hundred consecutive surgically resected patients with pancreatic ductal adenocarcinoma were included in the study. They were further divided into 2 groups: pre-protocol, evaluated before the introduction of the standardized protocol and post-protocol, analyzed with the standardized p…

Videolaparoscopic cholecystectomy in patients with previous abdominal surgery. Personal experience and literature review

2017

Objectives. Laparoscopic cholecystectomy (LC) is today the "gold standard" treatment of gallbladder stones. Role of LC is still debated in the presence of abdominal scars due to the frequent post-operative adhesions which make access to the peritoneal cavity difficult. This study aim to assess role and outcomes of LC on a previous abdominal surgery on the scarred abdomen. Materials and Methods. we have carried out a retrospective study on 499 consecutive patients who had undergone LC from 2009 to 2015; 21 of these (4.2%) undergone previous abdominal surgery. In all 21 cases the pneumoperitoneum was established with Veress needle at the Palmer's point and the procedure was carried out after …

A Study of the Septa in the Maxillary Sinuses and the Subantral Alveolar Processes in 30 Patients

2008

The objective of this paper is to study the incidence of septa in the maxillary sinus and measure the height of the underlying alveolar process using panoramic radiography and computerized tomography (CT scans). Thirty patients who were going to be treated with dental implants were submitted to panoramic radiographs and CT scans. Sixty maxillary sinuses were analysed and divided into 2 groups: group 1 (totally edentulous) and group 2 (partially edentulous). The sinuses were divided into 3 regions (anterior, middle, and posterior), the septa were analysed, and the heights of the alveolar processes were calculated in these 3 areas. Of the 30 patients, 36.5% had maxillary sinuses, and 25% of t…

ROUTINARY USE OF FIBRIN SEALANTS TO PREVENT PROLONGED AIR LEAK IN THORACIC SURGERT: OUR EXPERIENCE

2019

Introduction: prolonged air leak (PAL) is one of the most common postoperative complications after lung surgery. It is associatred with increased significant morbidity, lower quality of life, longer hospital stay and higher hospital costs. Since its great clinical and economic burden, it is important to establish the feasibility and the effectiveness of the routinary preventive use of a fibrin sealant in order to reduce the incidence of prolonged air leaks. Patients and methods: this is a randomized study on 189 adult patients - 118 men (62,4%) and 71 women (37,6%) aged from 39 to 87 y.o. (mean age 68,3 y.o.) - who underwent lung surgery (lobectomy or bilobectomy) with intraoperatory detect…
