Peripheral giant cell granuloma (PGCG) associated to dental implants is a very infrequent peri-implant soft-tissue complication, with only 11 cases recorded in the literature to date. The present study describes a 54-year-old woman presenting a swelling of the alveolar margin in the fourth quadrant in relation to a fixed prosthesis cemented over implants. Treatment consisted of complete resection of the lesion with implantoplasty of the exposed implant threads. The diagnosis of PGCG was confirmed by histological study, and no relapse has been recorded after 12 months of follow-up.

Local protein synthesis (LPS) in axons is now recognized as a physiological process, participating both in the maintenance of axonal function and diverse plastic phenomena. In the last decades of the 20th century, the existence and function of axonal LPS were topics of significant debate. Very early, axonal LPS was thought not to occur at all and was later accepted to play roles only during development or in response to specific conditions.

Objectives: Giant cell arteritis (GCA) is a large/medium-vessel granulomatous vasculitis, and the PD-1/PD-L1 coinhibitory pathway seems to be implicated in its pathogenesis. CD4 T cells expressing high PD-1 levels, CD4+CXCR5-PD-1hi peripheral helper (Tph) and CD4+CXCR5+PD-1hi follicular helper T cells (Tfh), are key mediators of autoimmunity. Their frequencies are elevated in the peripheral blood of subjects with several autoimmune conditions but have not been investigated in GCA.

Acute promyelocytic leukaemia (APL) is a highly lethal haematological malignancy. It is rare in pregnancy and may be fatal if not managed promptly and appropriately. A woman in her 20s presented with high-grade fever at 16 weeks of her third pregnancy.

Development of an understanding of membrane nanodomains colloquially known as "lipid rafts" has been hindered by a lack of pharmacological tools to manipulate rafts and protein affinity for rafts. We screened 24,000 small molecules for modulators of the affinity of peripheral myelin protein 22 (PMP22) for rafts in giant plasma membrane vesicles (GPMVs). Hits were counter-screened against another raft protein, MAL, and tested for impact on raft , leading to two classes of compounds.

Pulmonary sclerosing pneumocytoma is a rare benign neoplasm typically seen in middle-aged women. The exact preoperative diagnosis is quite challenging considering its nonspecific clinical and radiologic features along with complex histology. Moreover, obtaining an exact histopathological diagnosis can be difficult especially with the small biopsy specimens.
