No full textNEW MISSIONS AND SCENARIOS FOR ARMED FORCES AND ITS IMPLICATIONS IN CIVIL – MILITARY RELATIONS
No full textThe transformations in the area of security and defense, and the complexity of the context in which the armed forces operate, had demanded to a closer political and military leadership over the conduct of operations, along with a more intense and specialized civil – military interaction, as a key factor to face uncertainty and ambiguity that characterizes the current operational environment. This fact has brought up some worries due to the possible military interference in the political area, especially within the circumstances of complex military operations in the tactical field, as well as, the civil expertise to exert the normal authority and leadership in civil -military relations and to assume the responsibility of their decisions.
The author analyses the changes that had occurred in missions and contexts where the armed forces are being employed, and from that, addresses the demands this new situation imposes to the civilian and military leaders; at the same time addresses the need to move forward in the design of relations and work procedures formulas, more explicit and institutionalized that may contribute to facilitate a better interaction able to add value to the decision – making process, in a coherent framework within the civil – military relations principles
Is navigation-guided en bloc resection advantageous compared with intralesional curettage for locally aggressive bone tumors?
No full textBackground: The treatment of locally aggressive bone tumors is a balance between achieving local tumor control and surgical morbidity.Wide resection decreases the likelihood of local recurrence, although wide resection may result in more complications than would happen after curettage.Navigationassisted surgery may allow more precise resection, perhaps making it possible to expand the procedures indications and decrease the likelihood of recurrence; however, to our knowledge, comparative studies have not been performed. Questions/purposes The purpose of this study was to compare curettage plus phenol as a local adjuvant with navigation-guided en bloc resection in terms of (1) local recurrence; (2) nononcologic complications; and (3) function as measured by revised Musculoskeletal Tumor Society (MSTS) scores. Methods Patients with a metaphyseal and/or epiphyseal locally aggressive primary bone tumor treated by curettage and adjuvant therapy or en bloc resection assisted by navigation between 2010 and 2014were considered for this retrospective study. Patients with a histologic diagnosis of a primary aggressive benign bone tumor or low-grade chondrosarcoma were included. During this time period, we treated 45 patients with curettage of whom 43 (95%)were available for followup at a minimum of 24 months (mean, 37 months; range, 24-61 months), andwe treated 26 patientswith navigation-guided en bloc resection, of whom all (100%) were available for study. During this period, we generally performed curettage with phenol when the lesionwas in contactwith subchondral bone. We treated tumors that were at least 5 mm from the subchondral bone, such that en bloc resection was considered possible with computer-Assisted block resection. There were no differences in terms of age, gender, tumor type, or tumor location between the groups. Outcomes, including allograft healing, nonunion, tumor recurrence, fracture, hardware failure, infection, and revised MSTS score, were recorded. Bone consolidation was defined as complete periosteal and endosteal bridging visible between the allograft-host junctions in at least two different radiographic views and the absence of pain and instability in the union site. All study data were obtained from our longitudinally maintained oncology database. Results In the curettage group, two patients developed a local recurrence, and no local recurrences were recorded in patients treated with en bloc resection. All patients who underwent navigation-guided resection achieved tumorfree margins. Intraoperative navigation was performed successfully in all patients and there were no failures in registration. Postoperative complications did not differ between the groups: in patients undergoing curettage, 7%(three of 43) and in patients undergoing navigation, 4% (one of 26) had a complication. There was no difference in functional scores: mean MSTS score for patients undergoing curettage was 28 points (range, 2730 points) and for patients undergoing navigation, 29 (range, 27-30 points; p = 0.10). Conclusions In this small comparative series, navigationassisted resection techniques allowed conservative en bloc resection of locally aggressive primary bone tumors with no local recurrence. Nevertheless, with the numbers available, we saw no difference between the groups in terms of local recurrence risk, complications, or function. Until or unless studies demonstrate an advantage to navigation-guided en bloc resection, we cannot recommend wide use of this novel technique because it adds surgical time and expense.
