Awake Craniotomy for Astrocytoma in the Left Frontal Lobe Using Augmented Reality Superimposing Tumor and White Matter Tracts: 2-Dimensional Operative Video.

Augmented reality (AR) is expected to serve as an assistive intraoperative technology in neurosurgery.1 Awake craniotomy (AC) for gliomas benefits the extent of resection, survival, and postoperative neurofunctional outcomes.2 In AC, it is critical to understand the cortical and subcortical anatomy.3 We describe the use of AR superimposing tumor and deep white matter tracts in AC. A 29-year-old right-handed woman presented to a local hospital after an episode of generalized convulsions. MRI of the head revealed a widely spreading tumor in the left middle frontal gyrus. After a left frontal craniotomy while the patient was asleep, AR was used to indicate the tumor boundary with subcortical fibers including the corticospinal tract, inferior fronto-occipital fasciculus, and cingulate fasciculus. We performed AR-assisted removal of the tumor on the surface of the middle frontal gyrus. On subcortical stimulation (SCS) of the frontal aslant tract and inferior fronto-occipital fasciculus, the patient stopped naming objects in the picture-naming test, while SCS of the left cingulate gyrus caused the patient to mistake colors in the Stroop test. The subcortical fibers identified by AR coincided with the sites of symptom elicitation by SCS. We eventually removed a large part of the tumor. Postoperative MRI confirmed 96.2% resection. The patient was discharged without any new neurological deficits. AC with AR is useful for resection of gliomas in the dominant hemisphere. The patient consented to the procedure and to the publication of her image. The ethics committee of our hospital does not require approval for case reports.

FEASIBILITY STUDY ON SWALLOWING TELEREHABILITATION IN PATIENTS WITH CORONAVIRUS DISEASE 2019.

Objective: Direct swallowing rehabilitation assessment in patients with highly infectious diseases, such as COVID-19, is not recommended. We aimed to explore the feasibility of using telerehabilitation for managing dysphagia in patients with COVID-19 in isolated hospital rooms. Design: Open-label trial. Subjects/patients: We examined 7 enrolled patients with COVID-19 who presented with dysphagia and were treated with telerehabilitation. Methods: Telerehabilitation was performed for 20 min daily and included indirect and direct swallowing training. Dysphagia was assessed before and after telerehabilitation using the 10-item Eating Assessment Tool, the Mann Assessment of Swallowing Ability and graphical evaluation using tablet device cameras. Results: All patients showed significant improvement in swallowing ability, evaluated by the range of the upward movement of their larynxes and the Eating Assessment Tool and Mann Assessment of Swallowing Ability scores. The change in swallowing evaluation scores was correlated with the number of telerehabilitation sessions. There was no infection spread to the medical staff treating these patients. Dysphagia in patients with COVID-19 was improved using telerehabilitation while ensuring a high degree of safety for clinicians. Conclusion: Telerehabilitation might eliminate the risks associated with patient contact and has the advantage of infection control. Its feasibility needs further exploration.

Improvement in Tongue Pressure Precedes Improvement in Dysphagia in Dermatomyositis.

Dysphagia is known to occur in patients with dermatomyositis. However, the sudden-onset dysphagia without other symptoms can make diagnosis and treatment challenging. Two patients who did not have a severe muscle weakness complained of the sudden inability to swallow solids and liquids. The muscle biopsy results showed the perifascicular atrophy, and the patients were diagnosed with dermatomyositis. Videofluoroscopy revealed an inadequate pharyngeal contraction and a decreased upper esophageal sphincter opening with silent aspiration. Both patients showed low tongue pressures. Patient 1 received intravenous and oral methylprednisolone, and patient 2 received intravenous immunoglobulin in addition to intravenous and oral methylprednisolone. Several months after the onset of the dysphagia, the swallowing function of both patients improved. The improvement in tongue pressure preceded an improvement in the subjective and objective measurements of dysphagia. In conclusion, tongue pressure may be useful for predicting early improvement in swallowing function.

Oropharyngeal dysphagia telerehabilitation in the Intensive Care Unit for COVID-19: a case report.

The face-to-face assessment of and training for dysphagia are considered aerosol-generating procedures, and thus are contraindicated for patients who are positive or suspected of having severe acute respiratory syndrome coronavirus 2 infection. Considering the extremely infectious nature of the virus, transmission to other individuals during rehabilitation is possible. Some patients in the intensive care unit and those who are on endotracheal intubation and mechanical ventilation often have dysphagia. Therefore, assessment and training for oropharyngeal dysphagia are provided by rehabilitation professionals to restore normal feeding before patient discharged. Thus, we aimed to explore the advantages of telerehabilitation in dysphagia management during the coronavirus disease 2019 (COVID-19) pandemic. An infected 50-year-old man admitted to the hospital underwent extracorporeal membrane oxygenation rescue therapy and tracheostomy. Upon gradual respiratory status stabilization, extracorporeal membrane oxygenation therapy was discontinued, and he was weaned off the ventilator. He had difficulty swallowing and coughed after attempting to drink fluids. We considered the application of telerehabilitation for managing dysphagia while minimizing the risk of infection and usage of personal protective equipment. A videoconferencing software on a tablet device provided contactless telerehabilitation, thus reducing the risk of infection and preventing personal protective equipment shortage. Moreover, it facilitates discussion on the issues related to the evaluation of oropharyngeal dysphagia telerehabilitation. We highlight important considerations for the application of telerehabilitation in the assessment and treatment of dysphagia during the COVID-19 pandemic.

[A case of the palatal tremor that disappeared during swallowing, thought to be caused by microbleeds of bilateral dentate nucleus].

A 72-year-old female presented with slowly progressive dysphonia, which was a syllable-separated utterance, for three years. She had the rhythmic continues contraction of palatal and uvula muscles during speech with a frequency of about 2 Hz. The videoendoscopy showed that the rhythmic contraction, which synchronized in the nasopharynx and the larynx, did not disappear during vocalization. The swallowing videofluorography showed that the rhythmic contraction disappeared transiently during the swallowing reflex, and there was no aspiration. The MRI revealed olivary pseudohypertrophy and multiple microbleedings including the bilateral dentate nucleus. The degeneration of olivary nucleus secondary to the bilateral asymptomatic dentate nucleus microbleedings within the dentato-rubro-olivary pathway was thought to be a cause of palatal tremor. This is a first report that a dynamic relation between vocalization and swallowing in palatal tremor.

Treatment of transient prosopagnosia with a tyrosine kinase inhibitor in a case of brain metastasis from EGFR-mutated lung adenocarcinoma.

Background: Prosopagnosia is a rare form of apraxia, in which a person has normal memory and vision, but has impaired cognition of human faces that are manifested through symptoms such as not being able to recognize the face of a familiar person, one has known or not being able to remember the face of a person. Here, we report the case of a patient with transient prosopagnosia associated with brain metastasis from epidermal growth factor receptor (EGFR)-mutated lung adenocarcinoma who was treated with tyrosine kinase inhibitors (TKIs). Case Description: A 52-year-old right-handed man with lung adenocarcinoma was introduced to our department because brain metastasis. On admission, he complained that he could not recognize his wife's face, but he could recall her face based on her voice. MRI revealed a right temporo-occipital enhancing lesion with perifocal edema and dissemination that were indicative of brain metastasis from lung adenocarcinoma. Two weeks after open biopsy, he was started on TKI therapy with osimertinib at a dosage of 80 mg/day. An MRI scan taken 1 month later revealed shrinkage of the metastasis. In addition, he had recovered from transient prosopagnosia and returned to normal life. Conclusion: In this study, the TKI osimertinib was administered to a patient with brain metastasis of EGFR-mutated lung adenocarcinoma who presented with prosopagnosia, and the patient's lesion shrunk and his symptoms were reversed with this treatment.
