Prospective Trial for the Evaluation of Radiogenomics in Advanced Rectal Cancer
In patients with advanced rectal cancer, molecular subtypes will be identified by preoperative biopsy, CT, MRI / PET radiomics analysis, clinical features, and clinical features will be confirmed and compared. Also, we want to confirm the relationship between these factors and the treatment response after chemoradiotherapy before surgery. The prognosis …

Improvement of Immunologic and Molecular Techniques for the Diagnosis and Follow-up of Patients With Thrombotic Thrombocytopenic Purpura
The lack of ADAMTS13 is the only biological marker that is specific for aTTP diagnosis8 and the assessment of ADAMTS13 is of clinical importance because it is essential for the rapid differential diagnosis between aTTP and other TMA. Furthermore, monitoring of ADAMTS13 activity is useful to ensure biological remission (ADAMTS13 …
Effect of Esophageal Contractile Reserve on Changes in Esophageal Motility and Symptoms After ARS in Patients With GERD
rapid swallow (MRS) can assess the contractile reserve capacity of the oesophageal body and identify and diagnose oesophageal motility disorders, but the impact of preoperative oesophageal reserve capacity on postoperative symptoms and motility in patients with GERD remains unclear. The aim of this study was to assess the effect of …
Audio-vestibular Evaluation of Children and Young Adults With Osteogenesis Imperfecta
The aim is to determine whether vestibular deficits are present in OI, then to establish whether a correlation exists between genetic type, severity of OI and audiovestibular phenotype. OI patients aged 12 to 20 years will undergo an audiometric, immittance, and vestibular assessment. When hearing loss is conductive or mixed …
Structural and Functional Characterization of Rare Ocular Diseases
Rare ocular diseases (ROD) are a heterogeneous group of ocular diseases that affect very few people and, generally, for which no tretament is available. An important subgroup of these diseases are inherited retinal degenerations. In this study we focus on understanding the natural history of different ROD that affect the …
