Anti-phospholipids antibodies and immune complexes in COVID-19 patients: a putative role in disease course for anti-annexin-V antibodies.

Introduction: Besides distinctive respiratory and digestive hallmarks, COVID-19 has been recently associated with a high prevalence of pro-inflammatory and hypercoagulable states known as "COVID-19 Associated Coagulopathy" (CAC), corresponding to a worsening in patients' conditions, whose causes are still to be elucidated. A link between anti-phospholipid antibodies (aPLs) and viral infections has long been suggested. APLs are assessed for anti-phospholipid syndrome (APS) diagnosis, characterized by thrombocytopenia, thrombosis, and coagulopathy.

Fatal infections in andrology. Atypical clinical presentation of a Fournier's disease.

Background: Fournier disease (FD) is a worrisome infection of genital area caused by a polimicrobial infection and characterized by a rapid progression to necrosis. Scrotum, perineum and lower abdomen represent the primary sites of origin. Clinical presentation and laboratory strongly suggest FD, but if not precociously diagnosed, it may quickly evolve into septic syndrome and patient's death.

Primary small-cell neuroendocrine carcinoma of the bladder: Case report and literature review.

Background: Neuroendocrine tumours (NET) are extremely rare and aggressive. Although they commonly affect intestine, many organs may be involved such as pancreas, lung or urinary tract. Bladder is rarely involved.

Advanced chondrosarcoma of the pelvis: A rare case of urinary obstruction.

Chondrosarcoma is the second most common malignant tumor of the bone with an incidence of 1 in 200.000 per year. Axial skeleton is frequently involved showing poorer oncological outcomes than appendicular one: human pelvis is a site predilection.

Toxic effects of expanded ataxin-1 involve mechanical instability of the nuclear membrane.

Ataxin 1 (ATXN1) is the protein involved in spinocerebellar ataxia type 1, one of nine dominantly inherited neurodegenerative diseases triggered by polyglutamine expansion. One of the isolated polyglutamine tracts properties is to interact with lipid bilayers. Here we used a multidisciplinary approach to test whether one of the mechanisms responsible for neuronal degeneration involves the destabilization of the nuclear membrane.
