Posterior arm perforator flap for coverage of the scapular area.

We report on using a pedicled posterior brachial perforator flap to cover a defect of the infraspinous fossa. The first description of the posterior brachial flap came from Masquelet in 1985, and there are very few reports of this flap in the literature, mainly in its pedicled form limited to axillary covers. Scapular soft tissue defect with bone exposure can be covered by several techniques.

The role of antibody therapies in treating relapsed chronic lymphocytic leukemia: a review.

Introduction: Chronic lymphocytic leukemia (CLL) is one of the most common types of leukemia in adult patients. The landscape of CLL therapy has changed in the last decades with the introduction of antibody-based therapies and novel targeted agents resulting in improved outcomes.

Areas Covered: This article describes the use of monoclonal antibodies, bispecific antibodies and antibody-drug conjugates in the treatment of relapsed and refractory CLL.

Vascularized posterior interosseous nerve graft for digital neurovascular bundle reconstruction.

Introduction: Despite the progress in microsurgery in recent decades, neurovascular bundle defects during ring finger injuries still pose challenges for the surgeon. Usually, a reversed venous graft and a non-vascularized nerve graft are utilized to reconstruct this defect. One of the most common challenges encountered when using a venous graft is the caliber mismatch between the graft and the digital arterial ends.

Programmed Cell Death Protein-1 Regulation in Response to SARS-CoV-2 in Paediatric Multisystem Inflammatory Syndrome Temporally Associated with SARS-CoV-2: A Prospective Cohort Study.

The role of programmed death cell protein 1 (PD-1) has already been described in a range of various diseases, including COVID-19. This study provides new, innovative data, related to the expression of PD-1 and the risk of Paediatric Inflammatory Multisystem Syndrome, temporally associated with SARS-CoV-2 infection (PIMS-TS)-a rare, but potentially life-threatening complication of COVID-19. In this study, we evaluated the expression of PD-1 protein in patients with PIMS.

Cytotoxic Activity of Melatonin Alone and in Combination with Doxorubicin and/or Dexamethasone on Diffuse Large B-Cell Lymphoma Cells in In Vitro Conditions.

Melatonin (MLT), a pineal gland hormone, not only regulates circadian and seasonal rhythms, but also plays an important role in many aspects of human physiology and pathophysiology. MLT is of great interest as a natural substance with anti-cancer activities. The aim of this study was to assess the cytotoxicity and apoptosis of MLT, used alone or in combination with one of the most active anti-cancer drugs, doxorubicin (DOX), and a well-known anti-inflammatory drug, dexamethasone (DEX), on a diffuse large B-cell lymphoma (DLBCL)-derived cell line.
