336 Is a vaginectomy enough or is a pelvic exenteration always required for surgical treatment of recurrent cervical cancer?

2020

Introduction No consensus has yet been reached on the best strategy for treatment of cervical cancer local recurrence. Vaginectomy could be a salvage treatment in selected patients. Methods The records of vaginal recurrent cervical cancer patients admitted at Fondazione Policlinico ‘Agostino Gemelli’ IRCCS in Rome from January 2010 to June 2019 were retrospectively analyzed. We reported perioperative and survival outcomes of vaginectomy with respect to a matched series of pelvic exenteration (PE). Results Fifteen women underwent vaginectomy and 30 patients were submitted to PE. No statistical differences were observed between the two groups at baseline characteristics. The vaginectomy proce…

Scientometrics analysis of research activity and collaboration patterns in Chagas cardiomyopathy.

2018

Background Chagas cardiomyopathy is a serious and common complication of Chagas disease. Methods Through bibliometric and Social Network Analysis, we examined patterns of research on Chagas cardiomyopathy, identifying the main countries, authors, research clusters, and topics addressed; and measuring the contribution of different countries. Results We found 1932 documents on Chagas cardiomyopathy in the MEDLINE database. The most common document type was ‘journal article’, accounting for 79.6% of the total (n = 1538), followed by ‘review’ (n = 217, 11.2%). The number of published records increased from 156 in 1980–1984 to 311 in 2010–2014. Only 2.5% were clinical trials. Brazil and the USA …

One-Year Quality of Life Trends in Early-Stage Lung Cancer Patients After Lobectomy

2020

Objective: Quality of Life (QoL) is an important predictor of patient's recovery and survival in lung cancer patients. The aim of the present study is to identify 1-year trends of lung cancer patients' QoL after robot-assisted or traditional lobectomy and investigate whether clinical (e.g., pre-surgery QoL, type of surgery, and perioperative complications) and sociodemographic variables (e.g., age) may predict these trends.Methods: An Italian sample of 176 lung cancer patients undergoing lobectomy completed the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire—Core 30 (QLQ-C30) at the pre-hospitalization (t0), 30 days (t1), 4 months (t2), 8 mon…

Cooperatively Enhanced Ion Pair Binding with a Hybrid Receptor

2015

A simple 18-crown-6-based bis-urea receptor R(1) was synthesized in three steps from a commercial starting material. The receptor's behavior toward anions, cations, and ion pairs was studied in solution with (1)H NMR, in solid state with single-crystal X-ray diffraction, and in gas phase with mass spectrometry. In 4:1 CDCl3/dimethyl sulfoxide solution the receptor's binding preference of halide anions is I(-) < Br(-) < Cl(-) following the trend of the hydrogen-bonding acceptor ability of the anions. The receptor shows a remarkable positive cooperativity toward halide anions Cl(-), Br(-), and I(-) when complexed with Na(+), K(+), or Rb(+). The solid-state binding modes of R(1) with alkali an…

Comparative cytotoxicity evaluation of eight root canal sealers

2017

Background The aim of the present study is to evaluate and compare the cytotoxic effects of eight root canal sealers (BioRoot RCS, TotalFill BC Sealer, MTA Fillapex, Sealapex, AH Plus, EasySeal, Pulp Canal Sealer, N2) on immortalized human gingival fibroblasts over a period of 24, 48 and 72 hours. Material and Methods Immortalized human gingival fibroblast-1 HGF-1 (ATCC CRL-2014) were incubated. Root canal sealers were then placed into sterile, cylindrical Teflon moulds. The extraction was made eluting the sealers in cell culture medium. Cells (1 × 104) were seeded in each well of a 96-well plate and incubated for 24 h at 37°C. Cultures were then exposed to 100 μL of the extracts medium. Th…

Intensity-modulated extended-field chemoradiation plus simultaneous integrated boost in the pre-operative treatment of locally advanced cervical canc…

2015

Objective: To investigate the feasibility and determine the recommended pre-operative intensity-modulated radiotherapy (IMRT) dose of extended-field chemoradiation along with simultaneous integrated boost (SIB) dose escalation. Methods: A radiation dose of 40Gy over 4 weeks, 2Gy/fraction, was delivered to the tumour and the lymphatic drainage (planning target volume, PTV3), which encompassed a volume larger than standard (common iliac lymphatic area up to its apex, in front of the L3 vertebra), concurrently with chemotherapy (cisplatin and 5-fluorouracil). Radiation dose was escalated to the pelvis (PTV2) and to the macroscopic disease (PTV1) with the SIB-IMRT strategy. Three dose levels we…

Use of bone scintigraphy in the early diagnosis of bisphosphonate related osteonecrosis of the jaw. Case report and review of the literature

2018

The main aim of the present report is to show the potential utility of bone scintigraphy for the diagnosis of jaw osteonecrosis. We report the history of a 62-year-old woman underwent breast cancer surgery in 2010. Moreover, patient received postoperative radiotherapy and chemotherapy. Intravenous bisphosphonates were also added to the treatment strategy to reduce the risk of bone metastasis. However, a hypermetabolic focus on left hemimandible was evidenced with a bone scintigraphy during follow up. After a careful study, the diagnosis of Bisphosphonate Related Ostneonecrosis of the Jaw (BRONJ) was carried out. This case highlights that bone scintigraphy may be extremely helpful for the ea…

Welche Vorteile bringt eine umfassende Diagnostik mit OPD-KJ bei kinder- und jugendpsychiatrischen Patienten?

2013

Fragestellung: Dieser Beitrag stellt die Vorteile einer umfassenden OPD-KJ Diagnostik für eine kinder- und jugendpsychiatrische Stichprobe dar. Methodik: Drei Achsen der OPD-KJ, die Konflikt- und Strukturachse sowie die Achse Behandlungsvoraussetzungen wurden zusätzlich zum MAS und der ICD-10 Diagnose an einer Gruppe von 61 stationären kinder- und jugendpsychiatrischen Patienten in Österreich eingeschätzt. Ergebnisse: Es zeigten sich deutliche Geschlechtsunterschiede in der Bedeutung internalisierter, entwicklungshemmender Konflikte, allerdings war das Strukturniveau bei allen Patienten einheitlich im Bereich gering bis mäßig angesiedelt, d. h. Strukturleistungen wie Umgang mit negativen A…

Effects of different intra canal medicaments on the push out bond strength of endodontic sealers

2016

BACKGROUND One of the essential properties of the root canal sealers is the adhesion to root canal dentin and their higher bond strength decreases the microleakage. The aim of the present study was to compare the effect of Different Intracanal medicaments on the push out bond strength of AH26 and MTA Fillapex sealers. MATERIAL AND METHODS A total of 104 one-rooted extracted human teeth were divided into 4 (n=26) experimental groups. After the cleaning and shaping, the root canals were filled with Ca(OH)2, triantibiotic paste (TAP), Metapex or 2% chlorhexidine gel for two weeks. Then, intracanal medicaments were rinsed away and the samples in the sub-groups were obturated with gutta-percha a…
