Implication of the Examining Pathologist to Meet the Oncologic Standard of Lymph Node Count after Laparoscopic Lymphadenectomy
2010
<i>Objective:</i> The lymph node number as benchmark in oncologic operations depends on the patient’s anatomy, surgeon’s skill and pathologist’s accuracy. The influence of the pathologist is barely evaluated. <i>Methods:</i> A retrospective analysis of lymph node numbers after 700 laparoscopic lymphadenectomies in correlation to the examining pathologists was done. Three surgeons from the same department performed all operations at 2 campi, where 2 separate pathology institutions exist. Lymph node specimens were assigned randomly to any of the 62 involved pathologists. <i>Results:</i> The mean number of lymph nodes was equal for all surgeons. Lymph node s…
Surgery-triggered and non surgery-triggered Bisphosphonate-related Osteonecrosis of the Jaws (BRONJ): A retrospective analysis of 567 cases in an Ita…
2011
Invasive local procedures are often reported in clinical history of patients suffering from Bisphosphonates-Related Osteonecrosis of the Jaws (BRONJ) but over 40% of spontaneous forms have been also described in literature. We compared age, gender, underlying bone disorders, bisphosphonate therapy, clinical features and surgical outcome of 205 cases (36.2%) of BRONJ non surgery-triggered (group 1) with 362 (63.8%) cases of surgery-triggered forms (group 2). Differences between group 1 and 2 were analysed using Mann-Whitney U and χ2 tests. Statistical analysis was performed using STATA 8. Zoledronate was the most used type of bisphosphonate (63.4% versus 69.0%) and the mandible was the most …
Sarcoma of the pulmonary artery: Report of two cases and a review of the literature
1992
Primary tumours of the pulmonary arteries are rare neoplasms seldom diagnosed during the patient's life time. We report on two cases of pulmonary artery sarcomas diagnosed during life time of the respective patients in intra-operative frozen sections by histopathological examination. Case 1 was of a 55-year-old man with a fibrosarcoma originating from the main pulmonary trunk. Case 2 was of a 43-year-old woman with a malignant fibrous histiocytoma originating from the right pulmonary artery. In both patients a radical tumour resection under cardiopulmonary bypass was attempted. Both patients, however, had a local tumour recurrence and died 18 months (patient 1) and 6 months (patient 2) afte…
Diagnosis and grading of acute graft-versus-host disease in endoscopic biopsy series throughout the upper and lower intestine in patients after allog…
2019
Intestinal graft-versus-host disease (GvHD) is a potentially life-threatening condition after allogenic hematological stem cell transplantation (alloHSCT). Although efforts have been made to determine the best sites for endoscopic biopsies, an approach involving all accessible anatomical regions is lacking. We investigated 22 complete biopsy series, each comprising biopsies from 10 different sites of the upper and lower intestine from 21 patients. The majority of biopsies investigated revealed histological signs of acute GvHD. The highest incidence and most advanced grades of acute GvHD were found in the right colon and terminal ileum. We detected significant correlations between crypt or g…
Cerebral oxygen saturation and cardiac output during anaesthesia in sitting position for neurosurgical procedures: a prospective observational study.
2016
Abstract Background Neurosurgical operations in the dorsal cranium often require the patient to be positioned in a sitting position. This can be associated with decreased cardiac output and cerebral hypoperfusion, and possibly, inadequate cerebral oxygenation. In the present study, cerebral oxygen saturation was measured during neurosurgery in the sitting position and correlated with cardiac output. Methods Perioperative cerebral oxygen saturation was measured continuously with two different monitors, INVOS® and FORE-SIGHT®. Cardiac output was measured at eight predefined time points using transoesophageal echocardiography. Results Forty patients were enrolled, but only 35 (20 female) were …
Real-time, ultrasound-guided infraclavicular axillary vein cannulation for renal replacement therapy in the critical care unit—A prospective interven…
2015
Abstract Purpose The cannulation of the axillary vein for renal replacement therapy is a rarely performed procedure in the critical care unit. We defined the venipuncture and catheterization success rates and early mechanical complication rates of this technique in critical care patients with acute kidney injury. Materials and methods Twenty-nine mechanically ventilated patients with clinical indications for insertion of temporary hemodialysis catheters enrolled in a registered trial (NCT01919528) as a pilot cohort. We performed 29 real-time, ultrasound-guided infraclavicular axillary vein cannulation attempts for renal replacement therapy. We defined the venipuncture and catheterization su…
Orthodontic camouflage versus orthognathic surgery for class III deformity: comparative cephalometric analysis
2017
The objective of this study was to compare different cephalometric variables in adult patients with class III malocclusions before and after treatment, in order to determine which variables are indicative of orthodontic camouflage or orthognathic surgery. The cases of 156 adult patients were assessed: 77 treated with orthodontic camouflage and 79 treated with orthodontics and orthognathic surgery. The following cephalometric variables were measured on pre-treatment (T1) and post-treatment (T2) lateral cephalograms: sella-nasion-A-point (SNA), sella-nasion-B-point (SNB), and A-point-nasion-B-point (ANB) angles, Wits appraisal, facial axis angle, mandibular plane angle, upper and lower inciso…
Accuracy between virtual surgical planning and actual outcomes in orthognathic surgery by iterative closest point algorithm and color maps: A retrosp…
2018
Background To evaluate the accuracy between actual outcomes and virtual surgical planning (VSP) in orthognathic surgery regarding the use of three-dimensional (3D) surface models for registration using iterative closest point (ICP) algorithm and generated color maps. Material and Methods Construction of planning and postoperative 3D models in STL files format (M0 and M1, respectively) from CBCT of 25 subjects who had been submitted to bimaxillary orthognathic surgery was performed. M0 and M1 were sent to Geomagic software in semi-automatic alignment surface mesh order of M0 and M1 for registration using ICP algorithm to calculate mean deviation (MD, MD+, MD-, SD) and root mean square (RMS –…
Implant treatment planning regarding augmentation procedures: panoramic radiographs vs. cone beam computed tomography images.
2015
Objectives To evaluate the impact of cone beam computed tomography (CBCT) imaging on treatment planning regarding augmentation procedures for implant placement. Material and methods Panoramic radiographs and CBCT images of 40 patients requesting single-tooth implants in 59 sites were retrospectively analyzed by six specialists in implantology, and treatment planning was performed. Therapeutic recommendations were compared with the surgical protocol performed initially. Results Bone height estimation from panoramic radiographs yielded to higher measures and greater variability compared to CBCT. The suggested treatment plan for lateral and vertical augmentation procedures based on CBCT or pan…
