Heparin induced thrombocytopenia (HIT) is a life and limb-threatening complication of heparin exposure. The misdiagnosis of this disease can have major consequences on the patients. The objective of this study was to evaluate a diagnostic strategy that combines the 4Ts score with the result of HemosIL® AcuStar HIT-IgG (PF4-H) to confirm the diagnosis of HIT. Citrated plasmas from 1300 patients with suspicion of HIT were analyzed with a fully automated quantitative chemiluminescent immunoassay (HemosIL® AcuStar HIT-IgG (PF4/H)). If the IgG anti-PF4/H antibodies were positive (cut-off, 1 U/mL), HIT diagnosis was confirmed using functional tests. In total, 1300 samples of consecutive patients were enrolled, 94 (7.2%) of which gave positive results in HemosIL® AcuStar-IgG. HIT was diagnosed in 65 out of these patients, corresponding to a prevalence of 5%. Using ROC curve analysis, patients were divided into three groups according to their titer of antibodies. Higher values of the IgG (PF4-H) were associated with increased probability of HIT, and the diagnostic specificity was greatly increased using the combination of a 4Ts score > 3 and a positive titer ≥ 3.25 U/mL. Importantly, the diagnostic specificity is 100% when the titer is > 12.40 U/mL. We demonstrated that higher values of Anti PF4/H Antibodies were associated with a high probability of having HIT. A titer of HemosIL® IgG (PF4-H) > 12.40 U/mL has a specificity of 100% which should no require a functional test to confirm the diagnosis of HIT.Disordered coagulation, endothelial dysfunction, dehydration and immobility contribute to a substantially elevated risk of deep venous thrombosis, pulmonary embolism (PE) and systemic thrombosis in coronavirus disease 2019 (Covid-19). We evaluated the prevalence of pulmonary thrombosis and reported RV (right ventricular) dilatation/dysfunction associated with Covid-19 in a tertiary referral Covid-19 centre. Of 370 patients, positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), 39 patients (mean age 62.3 ± 15 years, 56% male) underwent computed tomography pulmonary angiography (CTPA), due to increasing oxygen requirements or refractory hypoxia, not improving on oxygen, very elevated D-dimer or tachycardia disproportionate to clinical condition. Thrombosis in the pulmonary vasculature was found in 18 (46.2%) patients. However, pulmonary thrombosis did not predict survival (46.2% survivors vs 41.7% non-survivors, p = 0.796), but RV dilatation was less frequent among survivors (11.5% survivors vs 58.3% non-survivors, p = 0.002). Over the following month, we observed four Covid-19 patients, who were admitted with high and intermediate-high risk PE, and we treated them with UACTD (ultrasound-assisted catheter-directed thrombolysis), and four further patients, who were admitted with PE up to 4 weeks after recovery from Covid-19. Finally, we observed a case of RV dysfunction and pre-capillary pulmonary hypertension, associated with Covid-19 extensive lung disease. We demonstrated that pulmonary thrombosis is common in association with Covid-19. Also, the thrombotic risk in the pulmonary vasculature is present before and during hospital admission, and continues at least up to four weeks after discharge, and we present UACTD for high and intermediate-high risk PE management in Covid-19 patients.Dystonia is a clinically, genetically, and biologically heterogeneous hyperkinetic movement disorder caused by the dysfunctional activity of neural circuits involved in motor control. Our understanding of the molecular mechanisms underlying dystonia pathogenesis has tremendously grown thanks to the accelerated discovery of genes associated with monogenic dystonias (DYT-genes). Genetic discoveries, together with the development of a growing number of cellular and animal models of genetic defects responsible for dystonia, are allowing the identification of several areas of functional convergence among the protein products of multiple DYT-genes. Furthermore, unexpected functional links are being discovered in the downstream pathogenic molecular mechanisms of DYT-genes that were thought to be unrelated based on their primary molecular functions. Examples of these advances are the recognition that multiple DYT-genes are involved in (1) endoplasmic reticulum function and regulation of the integrated stress response (ISR) through Eukaryotic initiation factor 2 alpha signaling; (2) gene transcription modulation during neurodevelopment; (3) pre-and post-synaptic nigrostriatal dopaminergic signaling; and (4) presynaptic neurotransmitter vesicle release. More recently, genetic defects in the endo-lysosomal and autophagy pathways have also been implicated in the molecular pathophysiology of dystonia, suggesting the existence of mechanistic overlap with other movement disorders, such as Parkinson's disease. Importantly, the recognition that multiple DYT-genes coalesce in shared biological pathways is a crucial advance in our understanding of dystonias and will aid in the development of more effective therapeutic strategies by targeting these convergent molecular pathways.

The management for patients with vulvar cancer after sentinel lymph-node biopsy (SLNB) remains controversial. SD-208 nmr The aim of this study was to investigate the long-term outcomes of individualized management after SLNB for early stage vulvar cancer.

The medical records of patients with vulvar cancer treated by surgery involving SLNB between 2004 and 2019 were retrospectively reviewed. During this period, the inguinofemoral lymphadenectomy (IL) were performed with individualized strategy, while the postoperative intensity-modulated radiotherapy was planned with a consistent policy.

We identified 138 patients with at least one sentinel node detected, of whom 64 underwent further IL while 74 had SLNB only. Nodal metastases (pN+) were confirmed in 22 patients with IL and 16 without. Radiotherapy was scheduled with the dose of 60-70Gy for all pN+ patients and finally completed in 15 with IL and 15 without. The median follow-up time was 56months (6-156months). Recurrence was observed in 24 patients, of whom 10 were pN- at primary treatment.
