Giant cell angioblastoma is an extremely rare tumor of vascular origin, described at the end of the 20th century. It belongs to tumors with intermediate malignant potential and is characterized by locally infiltrative growth. The tumor doesn’t have any clear distinctive clinical characteristics. The diagnosis is established on the basis of histological examination. Two main treatment options for this pathology are discussed in the literature: radical removal of the tumor and therapy with low doses of interferon alpha. As a rule, this is a combination treatment. This article describes our own clinical case. The patient’s parents gave their consent to the use of their child’s data, including photographs, for research purposes and in publications. Interest is in the rarity of the disease and the features of the clinical characteristics of this case, specifically the extremely unfavorable localization in the oropharynx region and, accordingly, the impossibility of carrying out not only a radical removal of the tumor, but also its resection. The high probability of developing irreversible neurological complications in this age group associated with interferon alpha therapy questioned the possibility of its use. For the first time in this histological variant of a vascular tumor, chemotherapy was applied, including metronomic therapy with cyclophosphamide and vinblastine in combination with a liposomal form of doxorubicin. After 8 courses of chemotherapy, a complete clinical response was obtained with the restoration of the patency of the respiratory and digestive tracts. The observation period at the time writing of this article was 36 months.

AbstractTreatment options for patients with venous thromboembolism (VTE) include warfarin and direct oral anticoagulants (DOACs). Although DOACs are easier to administer than warfarin and do not require routine laboratory monitoring, few studies have directly assessed whether patients are more satisfied with DOACs. We surveyed adults from two large integrated health systems taking DOACs or warfarin for incident VTE occurring between January 1, 2015 and June 30, 2018. Treatment satisfaction was assessed using the validated Anti-Clot Treatment Scale (ACTS), divided into the ACTS Burdens and ACTS Benefits scores; higher scores indicate greater satisfaction. Mean treatment satisfaction was compared using multivariable linear regression, adjusting for patient demographic and clinical characteristics. The effect size of the difference in means was calculated using a Cohen’s d (0.20 is considered a small effect and ≥ 0.80 is considered large). We surveyed 2217 patients, 969 taking DOACs and 1248 taking warfarin at the time of survey. Thirty-one point five percent of the cohort was aged ≥ 75 years and 43.1% were women. DOAC users were on average more satisfied with anticoagulant treatment, with higher adjusted mean ACTS Burdens (50.18 v. 48.01, p < 0.0001) and ACTS Benefits scores (10.21 v. 9.84, p = 0.046) for DOACs vs. warfarin, respectively. The magnitude of the difference was small (Cohen’s d of 0.29 for ACTS Burdens and 0.12 for ACTS Benefits). Patients taking DOACs for venous thromboembolism were on average more satisfied with anticoagulant treatment than were warfarin users, although the magnitude of the difference was small.

Background. In our previous study, mouse double minute 2 homolog (MDM2), insulin-like growth factor 1 (IGF1), signal transducer and activator of transcription 1 (STAT1), and Rac family small GTPase 1 (RAC1) were correlated with the recurrence of giant cell tumor of bone (GCT). The aim of this study is to use a large cohort study to confirm the involvement of these four genes in GCT recurrence. Methods. The expression of these four genes was detected and compared between GCT patients with or without recurrence. The correlation between the expression of these four genes and clinical characteristics was evaluated. Protein-protein interaction (PPI) network was constructed for functional enrichment analysis. Results. It showed that the expression levels of MDM2, IGF1, STAT1, and RAC1 in GCT patients with recurrence were significantly higher than those in GCT patients without recurrence (P<0.05). Multivariate logistic regression analysis suggested that several clinical characteristics may influence prognosis. A PPI network was constructed using the four genes as hub genes. Functional enrichment analysis showed that this network involves many important biological progress mediated by these four genes, including immune response. Conclusion. MDM2, IGF1, STAT1, and RAC1 are associated with GCT recurrence, which might serve as biomarkers for GCT recurrence.

There are two categories of pulmonary edema: edema caused by increased capillary pressure (hydrostatic or cardiogenic edema) and edema caused by increased capillary permeability (noncardiogenic pulmonary edema, or acute respiratory distress syndrome). This review focuses on cardiogenic pulmonary edema and describes the general approach to patients with suspected cardiogenic pulmonary edema. The pathogenesis, diagnosis, treatment, and outcome of cardiogenic pulmonary edema are reviewed. Figures include chest scans showing pulmonary edema and noncardiogenic pulmonary edema, an illustration of the differences between cardiogenic and noncardiogenic edema, and a chart comparing lung mechanics and other variables in experimental models of cardiogenic pulmonary edema and noncardiogenic edema. Tables show clinical characteristics of patients with cardiogenic pulmonary edema and treatment options. This review contains 3 figures, 4 tables, and 24 references. Key words: cardiogenic pulmonary edema, congestive heart failure, pulmonary edema, Starling’s law

: Giant cell tumour of bone (GCTB) typically occurs in young adults from 20-40 years old. Although the majority of lesions are located in the epi-metaphyses of the long bones, approximately one third of tumours is located in the axial skeleton, of which only 4% in the sacrum. Sacral tumours tend to be large at the time of presentation, and they present with aggressive features such as marked cortical destruction and an associated soft tissue component. The 2020 World Health Organisation classification of Soft Tissue and Bone Tumours describes GCTB as neoplasm which is locally aggressive and rarely metastasizing. The tumour contains three different cell types: neoplastic mononuclear stromal cells, macrophages and osteoclast-like giant cells. Two tumour subtypes were defined: conventional GCTB and malignant GCTB. Only 1-4% of GCTB is malignant. In this review article, we will discuss imaging findings at the time of diagnosis to guide the musculoskeletal radiologist in reporting these tumours. In addition, imaging for response evaluation after various treatment options will be addressed, such as surgery, radiotherapy, embolization and denosumab. Specific findings will be presented per imaging modality and illustrated by cases from our tertiary sarcoma referral center. Common postoperative and post radiotherapy findings in GCTB of the sacrum on MRI will be discussed.
