Severe Psychosis Pursuing Corticosteroid Supervision.
Mean follow-up was 21.9 months (range 12 to 52). Average age was 50.4 years (range 28 to 61). The average preoperative ACFAS score of 49.6 (range 29 to 61) improved to 78 (range 51 to 92) at 10 weeks postoperatively and 85.4 (range 60 to 100) at 1 year postoperatively. By 1 year postsurgery, 9 of 10 patients (90%) described their satisfaction level as very satisfied, and 1 (10%) was somewhat satisfied. PURPOSE The hypertrophied peroneal tubercle may result in lateral ankle pain with peroneal tendon tenosynovitis and rupture. The aim of this study was to evaluate different configurations and dimensions of the normal peroneal tubercle using two-dimensional CT scan. METHODS Totally, 100 normal CT scans of cases older than 18 years of age were assessed to determine the shape of the peroneal tubercle. Moreover, height, length and width of different configurations of the normal peroneal tubercle were measured in axial and coronal sections of the ankle CT scans. RESULTS Four different configurations based on the axial cut of the calcaneus were found; single-convex (59%), double-convex (24%), plateau (9%), and convex-concave (8%) without statistically significant difference between genders (p-value 0.526). Totally, mean of height, length and width were 4.42 ± 1.38 mm, 28.88 ± 6.58 mm and 17.17 ± 3.85 mm, respectively. Although mean of the height in the single-convex and the double-convex types were 4.5 ± 1.4 mm and 5.0 ± 1.4 mm, respectively, the highest peroneal tubercle in the single-convex and the double-convex group were 10.2 mm and 8.5 mm, respectively. CONCLUSIONS In cases with lateral ankle pain and suspicious to hypertrophied peroneal tubercle, two-dimensional CT scan can be an available practical modality to identify the pathological type of the peroneal tubercle based on the presented classification and normal values. As previously reported in the literature, considering cut-off point of 5 mm could result in overdiagnosis of the hypertrophied peroneal tubercle, especially in single-convex type; however, clinical correlation is always paramount. LEVEL OF EVIDENCE Level IV. AIMS The European Organisation for Research and Treatment of Cancer (EORTC) 22,881-10,882 trial showed significant benefit of a radiotherapy boost (RTB) in women ≤40 years in a pre-hormone therapy (HT) era. We determined how the use of HT and RTB changed in response to clinical guidelines and whether the benefit of routine RTB was still observed in the HT era. MATERIALS AND METHODS Between 1996 and 2004, a provincial database identified all women ≤40 years with breast cancer who met the inclusion criteria of the EORTC trial. In total, 411 patients were classified into three eras defined by the guidelines era 1 (discretionary HT, discretionary RTB); era 2 (routine HT, discretionary RTB); era 3 (routine HT, routine RTB). HT use, RTB use and cumulative incidence of local recurrence were calculated and compared across eras. RESULTS HT use increased after the first policy change from 13% to 75% for oestrogen receptor-positive patients (P less then 0.01). RTB use also increased from 33% to 76% following the second policy change (P less then 0.01). At 10 years, the cumulative incidence of local recurrence was 12% in era 1, 6% in era 2 and 6% in era 3 (era 2 versus era 3, P = 0.92). For patients in the routine HT era (eras 2 and 3 combined) there was no significant difference in local recurrence between RTB and 'no RTB' patients (6% versus 7%, P = 0.81). CONCLUSIONS The routine use of HT and RTB increased significantly after new practice guidelines. Introduction of the HT guideline was associated with a 6% improvement in local recurrence at 10 years. No improvement in local recurrence was associated with the introduction of the RTB guideline in the HT era. The routine use of a boost in unselected young women with negative margins should be re-evaluated in the current HT era. The study aims to explore the combinatorial effect of naringin with antibiotics, ciprofloxacin and tetracycline on Pseudomonas aeruginosa biofilms. The antibiofilm efficacy of selected treatment regimes against P. aeruginosa biofilm were quantified by crystal violet assay, MTT assay, Congo red binding assay, and were visualized by confocal laser scanning microscopy and scanning electron microscopy. All the assays reflected antibiofilm activities, however, combinatorial performances of naringin with antibiotics were found to be more significant. A significant reduction in swimming and swarming motilities along with pellicle formation and altered colony morphology were observed as a result of combinatorial effect. The cytotoxicity of naringin and its antibiotic combinations was assayed on murine macrophage cell line. The applicability of such combinations was tested for their relative eradication against pre-formed biofilm on urinary catheter surface. This finding indicated that naringin potentiates the efficacy of both ciprofloxacin and tetracycline on P. aeruginosa biofilm in comparison to their solo treatment. The finding would help to open hitherto unexplored possibilities of establishing naringin as a potential antibiofilm agent and suggest on the possibility of its use in drug-herb combinations for managing biofilm-associated bacterial infections. RATIONALE AND OBJECTIVES Fractional flow reserve (FFR) is an established technique for detecting lesion-specific ischemia but is invasive. Our objective was to investigate the effects of combined assessment of coronary CT angiography (CCTA) imaging features and CT-FFR on detecting lesion-specific ischemia by comparing with invasive FFR. MATERIALS AND METHODS Forty-seven patients who had 60 coronary vessels with 30%-90% stenosis were included. Six anatomic CCTA descriptors (Agatston score, stenosis severity, mean plaque CT attenuation value, noncalcified and calcified plaque volumes, remodeling index) and a functional descriptor (CT-FFR) were measured. Random forest was used to identify which descriptors were useful to identify ischemia-related lesion. Depsipeptide Receiver-operating characteristic (ROC) curves were calculated for 2 models i.e. Model-1 for anatomical CT descriptors and Model-2 for anatomical CT descriptors plus CT-FFR. RESULTS Stenosis severity (40.8 ± 15.7% vs 57.6 ± 14.1%), noncalcified plaque volume (190 ± 100 vs 254.8 ± 133.3), and remodeling index (1.04 ± 0.12 vs 1.11 ± 0.13) were significantly higher in ischemia-related lesions than nonischemia-related lesions. CT-FFR was 0.84 ± 0.14 and 0.71 ± 0.14, respectively, for ischemia-related and nonischemia-related lesions, and the difference was significant. The area under the ROC curve was 0.738 and 0.835 in Model-1 and Model-2, respectively. Reclassification of ischemic lesion risk was significantly improved after adding CT-FFR net reclassification improvement was 0.297 and integrated discrimination improvement was 0.254. CONCLUSION Combined assessment of anatomical CCTA features and functional CT-FFR was helpful for detecting lesion-specific ischemia. Texture analysis is an emerging field that allows mathematical detection of changes in MRI signals that are not visible among image pixels. Alzheimer's disease, a progressive neurodegenerative disease, is the most common cause of dementia. Recently, multiple texture analysis studies in patients with Alzheimer's disease have been performed. This review summarizes the main contributors to Alzheimer's disease-associated cognitive decline, presents a brief overview of texture analysis, followed by review of various MR imaging texture analysis applications in Alzheimer's disease. We also discuss the current challenges for widespread clinical utilization. MR texture analysis could potentially be applied to develop neuroimaging biomarkers for use in Alzheimer's disease clinical trials and diagnosis. BACKGROUND Although nearly half of medical students are female there is still a significant discrepancy in the number of women specializing in radiology. In 2013, 26.9% of US diagnostic radiology residents were female, a 1% increase in 20 years from 25.5% in 1990. PURPOSE The purpose of this project is to determine the effectiveness of the interventions implemented at a single medical school at decreasing negative attitudes about radiology held by medical students of all genders and whether those same interventions will increase the number of female medical students matching into radiology. link2 METHODS The interventions were implemented between 2012 and 2016 and included incorporation of radiology into preclinical curriculum, electives in radiology for 3rd year students, a "Women in Radiology Panel," and increase in female radiology faculty visibility. First year medical student participants of all genders used a free text box to write their attitudes about radiology, which were categorized into the "six most com demonstrated a significant increase in the female match rate into the specialty when compared to female medical students who experienced three or fewer years of intervention. Additionally, it appears that these same interventions decreased the number of students of all genders having some of the common negative misperceptions about the field of radiology. BACKGROUND AIMS Autologous hematopoietic stem cell transplantation (AHSCT) is an alternative for multiple sclerosis (MS) patients who do not respond to conventional treatment. Mobilization kinetics of CD34+ cells in MS patients has not been studied. METHODS Patients with MS mobilized with granulocyte colony-stimulating factor (G-CSF) and cyclophosphamide (Cy) were prospectively studied. Three counts of CD34+ cells were done in peripheral blood at baseline before mobilization, at the start, and immediately at the end of apheresis. Complete blood counts were performed at the times of CD34+ cell counting. Standard statistical descriptive analysis of MS patients' salient features was performed, and after log 10 transformation of the data, Pearson test was performed to assess correlation between variables and CD34+ cell count. In addition, multiple linear regression of relevant data was carried out for multivariate analysis. RESULTS Data of 51 consecutive MS patients with median age of 48 (31-64) years were analyzed. The CD34+ cell count increased 26-fold after mobilization. During large volume leukapheresis (LVL), the number of CD34+ cells in peripheral blood increased from 51.29 CD34+/μL at the start to 62.3 CD34+/μL at the end. A negative correlation between CD34+ cell count after leukapheresis and age (r = -0.32, P = 0.02) was observed. Neither the CD34+ baseline count nor sex correlated with the CD34+ count in peripheral blood immediately at the end of apheresis. CONCLUSIONS Mobilization with G-CSF and Cy in MS patients resulted in effective CD34+ hematoprogenitors release from the bone marrow and in intra-apheresis recruitment. We analyzed data relative to cell content in 88 consecutive patients receiving HLA haploidentical bone marrow (BM) transplants with post-transplantation cyclophosphamide (PT-CY). Median age was 54.5 (range, 17-72); diagnoses were acute leukemia (n = 46), lymphoproliferative disorders (n = 24), myelofibrosis (n = 11) and myelodysplastic syndromes (n = 5). Total nucleated cell (TNC) and CD34+, CD3+, CD4+ and CD8+ cell doses were stratified as higher than first, second and third quartile and the dose effect on various clinical outcomes was assessed. link3 Median time to engraftment was 17 days for neutrophils and 24 days for platelets. To receive a dose of TNC ≥3.2 x 106/kg or CD34+ cells ≥2.7 x 106/kg significantly shortened the time to neutrophil and platelet engraftment and reduced the blood product requirements in the 30-day period after transplantation. Overall, TNC and CD34+ cell doses had no effect on acute graft-versus-host disease (GVHD) incidence, whereas patients receiving higher CD3+ and CD8+ cell doses seemed to have less chronic GVHD.
