Key Clinical Message: The purpose of this case report is to reveal one of the cardiovascular side effects of favipiravir, sinus bradycardia.
Abstract: Favipiravir has emerged as a potential treatment for COVID-19, with its antiviral properties showing promise in inhibiting viral replication. However, concerns regarding its safety profile, particularly its cardiac adverse effects, remain a subject of debate. We present the case of a 58-year-old man with a history of diabetes mellitus and chronic obstructive pulmonary disease who developed bradycardia following treatment with favipiravir for COVID-19 pneumonia. Despite being asymptomatic, the patient exhibited sinus bradycardia, which resolved upon discontinuation of favipiravir. Favipiravir has been associated with QT prolongation and sinus bradycardia, though the exact mechanisms remain unclear. Our case adds to the growing body of evidence highlighting the potential cardiac complications of favipiravir therapy in COVID-19 patients. Further research is warranted to clarify the underlying mechanisms and optimize patient management strategies. Clinicians should be cautious for cardiac adverse events when prescribing favipiravir for COVID-19 treatment, especially in patients with preexisting cardiac conditions. Continued research is essential to ensure the safe and effective use of favipiravir in the management of COVID-19.

A Childhood Langerhans Cell Histiocytosis With a Novel BRAFN486_T491delinsK Mutation: Good Response to Conventional Chemotherapy.

Langerhans cell histiocytosis (LCH) is characterized genetically by diverse gene mutations of the mitogen-activated protein kinase signaling cascade. BRAFN486_T491delinsK mutation is a rare mutation that involves the β2-αC ring domain, causing activation of the mitogen-activated protein kinase pathway, and is predicted to be resistant to the chemotherapy and BRAFV600E inhibitor in adult LCH cases. Here, we report a childhood LCH case with this novel BRAF mutation and had a good response to conventional chemotherapy.

Median craniofacial hypoplasia is characterized by tissue deficiency of the midline facial structures and/or brain. Patients can present with a wide variety of facial differences that may or may not require operative intervention. Common reconstructive procedures include cleft lip and/or palate repair, rhinoplasty, and orthognathic surgery, among others.

Collapsing glomerulopathy (CG) has a severe course typically associated with viral infections, especially HIV and parvovirus B19, systemic lupus erythematosus (SLE), among other etiologies. A 35-year-old woman with recent use of a JAK inhibitor due to rheumatoid arthritis presented with a 2-week history of fever, cervical adenopathy, and facial erythema. After admission, anemia, hypoalbuminemia, proteinuria, and severe acute kidney injury were noted.

This study aimed to develop a novel reconstruction method for segmental mandibulectomy. In the authors' opinion, reconstruction of the anterior border of the mandibular ramus using a double-arm vascularized fibular flap is important to prevent deformity due to buccal depression and the accumulation of food debris, thereby eliminating masticatory dead space that cannot be filled with prostheses such as implants or dentures. Using conventional reconstruction plates, the reconstructed bone positioned at the anterior border of the mandibular ramus required either fixing with only 1 screw or using 2 plates for stable fixation, making it difficult to position the plates stably.

Lipomas are benign soft tissue tumors composed of mature adipocytes, commonly found in subcutaneous tissues. Despite their prevalence in various body regions, they are relatively rare in the oral and maxillofacial regions. This study retrospectively analyzed the clinical and imaging characteristics, as well as the treatment outcomes of 57 patients diagnosed with lipoma.
