- En bloc vertebrectomy for the treatment of spinal lesions. Five years of experience in a single institution: a case series(2018) ARAUJO, Alex Oliveira de; NARAZAKI, Douglas Kenji; TEIXEIRA, William Gemio Jacobsen; GHILARDI, Cesar Salge; ARAUJO, Pedro Henrique Xavier Nabuco de; ZERATI, Antonio Eduardo; MARCON, Raphael Martus; CRISTANTE, Alexandre Fogaca; BARROS FILHO, Tarcisio Eloy Pessoa deOBJECTIVES: The objective of this study is to describe the experience of a Brazilian public university hospital regarding the treatment of metastatic or benign spine lesions with en bloc vertebrectomy of the thoracic and lumbar spines. METHODS: This study was a retrospective case series and included all medical records of patients with benign aggressive, primary malignant, or metastatic spine lesions who underwent en bloc vertebrectomy from 2010 to 2015. RESULTS: A total of 17 patients were included in the analysis. Most of them (71%) were indicated for surgery based on an oncologic resection for localized disease cure. Overall, 10 of the 17 patients (59%) underwent vertebrectomy via an isolated posterior approach using the technique described by Roy-Camille et al. and Tomita et al., while 7 patients (41%) underwent double approach surgeries. Of the 17 patients who underwent the en bloc resection, 8 are still alive and in the outpatient follow-up (47%), and almost all patients with metastatic lesions (8/9) died. The average survival time following the surgical procedure was 23.8 months. Considering the cases of metastatic lesions and the cases of localized disease (malignant or benign aggressive disease) separately, we observed an average survival time of 15 months and 47.6 months respectively. CONCLUSION: This study demonstrates and reinforces the reproducibility of the en bloc vertebrectomy technique described by Tomita et al.
- Role of Lock Therapy for Long-Term Catheter-Related Infections by Multidrug-Resistant Bacteria(2018) FREIRE, Maristela P.; PIERROTTI, Ligia C.; ZERATI, Antonio E.; BENITES, Luciana; MOTTA-LEAL FILHO, Joaquim Mauricio da; IBRAHIM, Karim Y.; ARAUJO, Pedro H.; ABDALA, EdsonThe management of long-term central venous catheter (LTCVC) infections by multidrug-resistant (MDR) bacteria in cancer patient is a challenge. The objectives of this study were to analyze outcomes in cancer patients with LTCVC-associated infection, identify risks for unfavorable outcomes, and determine the impact of MDR bacteria and antibiotic lock therapy (ALT) in managing such infections. We evaluated all LTCVC-associated infections treated between January 2009 and December 2016. Infections were reported in accordance with international guidelines for catheter-related infections. The outcome measures were 30-day mortality and treatment failure. We analyzed risk factors by Cox forward-stepwise regression. We identified 296 LTCVC-associated infections; 212 (71.6%) were classified as bloodstream infections (BSIs). The most common agent was Staphylococcus aureus. Forty-six (21.7%) infections were due to MDR Gram-negative bacteria. ALT was used in 62 (29.2%) patients, with a 75.9% success rate. Risk factors identified for failure of the initial treatment were having a high sequential organ failure assessment (SOFA) score at diagnosis of infection and being in palliative care; introduction of ALT at the start of treatment was identified as a protective factor. Risk factors identified for 30-day mortality after LTCVC-associated infection were a high SOFA score at diagnosis, infection with MDR bacteria, and palliative care; introduction of ALT at the start of treatment, hematological malignancies, and adherence to an institutional protocol for the management of LTCVC-associated infection were identified as protective factors. Despite the high incidence of infection with MDR bacteria, ALT improves the outcome of LTCVC-associated infection in cancer patients.
