An esthetic, functional, and low-invasive lower red lip reconstruction using a mucosal perforator flap: A case report.

Key Clinical Message: Lower red lip reconstruction using a mucosal perforator flap is low-invasive and adheres to the concept of "like with like." The location of the mucosal perforator can easily be detected using color Doppler ultrasound.

Abstract: Lip reconstructions should provide results of a high degree regarding both functionality and esthetics.

Work-related stress and coping methods of internists and primary care physicians during the COVID-19 pandemic in Japan: A mixed-method study.

Background: The COVID-19 pandemic has affected the mental health of health care workers. This study aimed to investigate the stress factors that cause burnout in Japanese physicians and their coping methods during the COVID-19 pandemic.

Methods: We conducted a sequential explanatory mixed-method study to investigate the psychological responses of physicians in the early stages of the pandemic.

Improvement in both severe obsessive-compulsive disorder and refractory tardive dystonia following electroconvulsive therapy: A case report.

Background: Obsessive-compulsive disorder (OCD) is often resistant to treatment and may be complicated by tardive dystonia (TDt) with the use of neuroleptics. Furthermore, patients with TDt often have an inadequate response to pharmacotherapy. Although electroconvulsive therapy (ECT) is considered a common treatment option for both TDt and OCD, its efficacy has not been well established for either condition.

Elliptical shadow on the cervical spinal cord.

Chiari type 1 deformation can show progressive degenerative neurological presentation in the elderly.

Pleuroparenchymal fibroelastosis after haematopoietic stem cell transplantation without graft-versus-host disease findings.

Although rare, pleuroparenchymal fibroelastosis (PPFE) is a serious late-onset complication of haematopoietic stem cell transplantation (HSCT). It remains unclear whether graft-versus-host disease (GVHD) is involved in the development of PPFE. We report the case of a patient with PPFE after HSCT.

Daily voluntary exercise enhances pilocarpine-induced saliva secretion and aquaporin 1 expression in rat submandibular glands.

Saliva-a water-based fluid containing electrolytes, immunoglobulins, and enzymes-has many functions, including the protection and hydration of mucosal structures within the oral cavity and the initiation of digestion. Aquaporins (AQPs) are proteins that act as water channels through membranes. We have previously reported upregulation of the expression levels of AQP 1 and 5 in the submandibular glands (SMGs) in heat-acclimated rats.
