Background: Amyotrophic lateral sclerosis (ALS) is known to cause generalized muscle atrophy and respiratory complications. Anesthetic agents and methods for patients with ALS are extremely important because they critically influence postoperative outcomes. In this clinical case, we mainly used remimazolam for safe anesthesia management.
Case Presentation: A 66-year-old man had a gradual onset of numbness and weakness in his extremities over 2 years. He was diagnosed with ALS after the appearance of dysarthria and restrictive ventilation disorder. Due to the rapid progression of respiratory dysfunction, the patient was placed on artificial respiration, and a tracheostomy was planned. General anesthesia was induced with remimazolam (6 mg/kg/h) and remifentanil (0.5 μg/kg/min). Tracheal intubation was performed without muscle relaxants, followed by total intravenous anesthesia (TIVA) with continuous administration of remimazolam 0.8-1.2 mg/kg/h and remifentanil 0.3-0.5 μg/kg/min. At the end of the surgery, the anesthetic effect of remimazolam was reversed with 0.4 mg of flumazenil. The patient was discharged from the operating room with stable breathing, and changes to preoperative ventilator settings were not necessary.
Conclusions: We safely performed tracheostomy for a patient with ALS using remimazolam during general anesthesia.

Background: There is limited knowledge about long-term mortality, care pathways and health-related quality of life (HrQoL) among intensive care unit (ICU) patients receiving prolonged mechanical ventilation (PMV).
Research Question: What are the long-term mortality, care pathways, and HrQoL of patients receiving invasive PMV, stratified by weaning success?
Study Design: and methods: We conducted a secondary analysis of patients from the cluster-randomised controlled Enhanced Recovery after Intensive Care trial who were treated in two ICU clusters and received invasive PMV (≥21 days via endotracheal tube/tracheostomy or ≥four days via tracheostomy). Data on weaning success, mortality, care place transitions, readmissions, and HrQoL were collected for six months after ICU discharge.
Riga-Fede disease (RFD) is a rare, benign condition marked by traumatic ulceration on the tongue's ventral side in infants. It arises from friction between the tongue and lower incisors during sucking, potentially worsening into a keratinized lesion if the cause is not addressed. This report details the case of a 1-year-6-month-old male with hydrocephalus, cleft palate, corpus callosum dysgenesis, neuropsychomotor developmental delay, and tracheostomy and gastrostomy needs.

Background: Invasive Candida infections (ICI) are the most common invasive fungal infections in solid organ transplant recipients. There are limited contemporary data on the risk factors for infection in heart transplant (HT) recipients especially since the expansion of temporary mechanical circulatory support (MCS) use.
Methods: This was a case-control study conducted at a tertiary care academic hospital of HT recipients from January 2022 to January 2024.
Potential effect of topical antibiotics administration in the oral cavity on the reduced number of bacteria entering the lower respiratory tract after oral cancer surgery.

Department of Oral and Maxillofacial Surgery, Nagasaki University Graduate School of Biomedical Sciences, Nagasaki, Japan.
Background/purpose: One of the causes of ventilator-associated pneumonia (VAP) is aspiration of oropharyngeal fluid containing pathogenic microorganisms into the lower respiratory tract. In this study, we aimed to investigate whether antibiotic ointment applied to the oral cavity can reduce the number of bacteria in the fluid on the cuff of a tracheal cannula.
Materials And Methods: Tetracycline ointment was applied intraorally once to a patient under endotracheal intubation by postoperative tracheostomy for oral cancer.
