Derived neutrophil-to-lymphocyte ratio has the potential to predict safety and outcomes of durvalumab after chemoradiation in non-small cell lung cancer.

The usefulness of the derived neutrophil-to-lymphocyte ratio (dNLR) and its dynamics before/after durvalumab consolidation therapy to predict safety or efficacy remains unclear. We retrospectively reviewed patients with locally advanced non-small cell lung cancer treated with durvalumab consolidation therapy after chemoradiotherapy (D group) or chemoradiotherapy alone (non-D group) at multiple institutions. We investigated the association between dNLR, or its dynamics, and pneumonitis, checkpoint inhibitor-related pneumonitis (CIP), irAEs, and efficacy.

Newly diagnosed ANCA-associated vasculitis after COVID-19 infection: a case report.

Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a systemic autoimmune disease characterized by mononuclear cell infiltration and small and medium-sized blood vessel destruction leading to renal failure. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been shown to have the potential to induce the presentation or exacerbation of autoimmune disease. This report describes the clinical features of a case of newly diagnosed ANCA-associated vasculitis after COVID-19 Infection.

Modified Lengthening Temporalis Myoplasty Using an Intraoral Approach.

Background: Lengthening temporalis myoplasty (LTM) is a unique and definite facial reanimation procedure that involves inserting the whole temporal tendon directly into the nasolabial fold. However, the nasolabial fold incision remains one of the difficulties of this procedure, particularly in young or female patient. To avoid the need for this incision, the authors developed an intraoral approach to manipulate the temporal muscle tendon toward the nasolabial fold.

Sliding Flap for the Wide Upper Eyelid Margin Defect After Cancer Removal.

Background: Reconstruction of eyelid margin defects following resection of upper-eyelid skin malignancies is typically performed using a lower eyelid switch flap, including eyelash reconstruction. However, a subsequent procedure for flap separation, and prolonged swelling of the flap may occur as a complication.

Objective: The authors performed anterior lamellar reconstruction using a sliding flap with excess upper eyelid skin, a procedure that is a less invasive and simpler.

Clinical analysis of 71 spontaneous pneumomediastinum cases: an observational study from a tertiary care hospital in Japan.

Background: Spontaneous pneumomediastinum is characterized by the presence of interstitial air in the mediastinum without any underlying disease. Some cases of spontaneous pneumomediastinum have been reported in the past, although only few reports are available, and its management remains uncertain. This study reviewed our experience in the diagnosis and treatment of spontaneous pneumomediastinum.
