BACKGROUND AND PURPOSE
Preclinical research demonstrated that the exposure of microbubbles (intravascular gas microspheres) to focussed ultrasound within the targeted tumour upregulates pro-apoptotic pathways and enhances radiation-induced tumour cell death. This study aimed to assess the safety and efficacy of magnetic resonance (MR)-guided focussed ultrasound-stimulated microbubbles (MRgFUS-MB) for head and neck cancers (HN).
MATERIALS AND METHODS
This prospective phase 1 clinical trial included patients with newly diagnosed or recurrent HN cancer (except nasopharynx malignancies) for whom locoregional radiotherapy with radical- or palliative-intent as deemed appropriate. Patients with contraindications for microbubble administration or contrast-enhanced MR were excluded. MR-coupled focussed ultrasound sonicated intravenously administered microbubbles within the MR-guided target volume. Patients receiving 5-10 and 33-35 radiation fractions were planned for 2 and 3 MRgFUS-MB treatments, respectively. Primary endpoint was toxicity per CTCAEv5.0. Secondary endpoint was tumour response at 3 months per RECIST 1.1 criteria.
RESULTS
Twelve patients were enrolled between Jun/2020 and Nov/2023, but 1 withdrew consent. Eleven patients were included in safety analysis. Median follow-up was 7 months (range, 0.3-38). Most patients had oropharyngeal cancer (55 %) and received 20-30 Gy/5-10 fractions (63 %). No systemic toxicity or MRgFUS-MB-related adverse events occurred. The most severe acute adverse events were radiation-related grade 3 toxicities in 6 patients (55 %; dermatitis in 3, mucositis in 1, dysphagia in 6). No radiation necrosis or grade 4/5 toxicities were reported. 8 patients were included in the 3-month tumour response assessment: 4 had partial response (50 %), 3 had complete response (37.5 %), and 1 had progressive disease (12.5 %).
CONCLUSIONS
MRgFUS-MB treatment was safe and associated with high rates of tumour response at 3 months.

Randomized Controlled Trial
Approximately 10% to 40% of patients with gastroesophageal reflux disease (GERD) exhibit poor response to proton pump inhibitors (PPIs), indicating refractory GERD (RGERD). Banxia Houpu Decoction is a traditional Chinese medicine formula used for treating GERD, particularly for atypical symptoms. This study aimed to investigate the improvement of different symptoms in RGERD patients treated with Banxia Houpu Decoction and identify relevant factors influencing its efficacy. From November 2021 to November 2022, a total of 89 RGERD patients voluntarily participated in this clinical study at our hospital. They were randomly assigned to 2 treatment groups: the Banxia Houpu Decoction group and the Western medicine group. The former received standard-dose Banxia Houpu Decoction, while the latter had a switch in PPI type with double-dose maintenance and the addition of magnesium aluminum carbonate as an acid suppressant. The improvement of different symptoms was compared between the 2 groups. Clinical data, including age, gender, gastric mucosal status, and esophagitis severity, were collected. Univariate analysis was performed to explore factors influencing the therapeutic effect of Banxia Houpu Decoction. Both treatment groups showed significant improvement in Frequency Scale for the Symptoms of GERD (FSSG) scores. The Banxia Houpu Decoction group exhibited the most significant efficacy in relieving throat burning sensation (P = .003) and frequent hiccups (P = .003). It also demonstrated improvement in swallowing difficulty (P = .048) and postprandial abdominal distension (P = .041), surpassing the Western medicine group. The Western medicine group had the most significant improvement in heartburn sensation (P = .008) and showed significant improvement in gastric burning sensation (P = .022), surpassing Banxia Houpu Decoction. Age (P = .025) and gastroesophageal flap valve (GEFV) grade (P = .014) were identified as factors influencing the efficacy of Banxia Houpu Decoction. Banxia Houpu Decoction exhibits superior efficacy compared to double-dose PPI combined with acid suppressants in relieving symptoms such as throat burning sensation, swallowing difficulty, and frequent hiccups. It shows significant efficacy in patients under 60 years of age and with GEFV grades I-II.

INTRODUCTION
The coronavirus disease 2019 (COVID-19) pandemic has profoundly affected the utilization of rehabilitation services. Existing evidence investigating this issue at the nationwide level is lacking, and it is uncertain whether the effects of the COVID-19 pandemic on the use of rehabilitation therapy of children and adolescents with cerebral palsy. This study aimed to investigate the impact of COVID-19 on the rehabilitation therapy of children and adolescents with cerebral palsy.
METHODS
We obtained data from South Korea's Health Insurance Review and Assessment Agency for 2017-2021. By analyzing the claims data, we focused on rehabilitation therapy in individuals with CP under 18 years of age. We categorized these according to therapy type (physical, occupational, or dysphagia), medical facility, hospital visits, and insurance. We calculated the patient counts and average claims per person and compared the average from before to during the COVID-19 pandemic.
RESULTS
Over the 5 years, there was a significant decline in the number of patients undergoing rehabilitation therapy (trend = 0.004), but the average claims per person remained stable (trend = 0.971). During the COVID-19 pandemic, the average number of claims per person decreased significantly compared to the control period ( = 0.013). Both the physical ( = 0.049) and occupational therapy groups ( = 0.019) showed significant differences in claims. General hospitals and hospitals experienced a decrease in average cases by 2.2 ( < 0.001) and 2.4 ( < 0.001) respectively, while long-term care hospitals increased by 3.1 cases ( < 0.001). Outpatients showed a decline of 2.0 cases ( < 0.001), whereas inpatients showed an increase of 5.9 cases ( < 0.001). Individuals with health insurance decreased by 0.5 cases ( = 0.007), but the decrease of 0.08 cases among medical aid-covered individuals was not statistically significant ( = 0.898).
CONCLUSION
In 2020-2021, the average number of claims per person showed a significant decrease compared to the pre-COVID-19 pandemic period (2017-2019). Depending on the type of treatment, the number of claims for physical and occupational therapy significantly decreased.

BACKGROUND
Aspiration and vocal fold mobility impairment (VFMI) are frequently reported in adults after cardiac surgery (CS) and impede recovery. Preoperative and postoperative laryngoscopic evaluations have not been undertaken, masking the incidence and evolution of dysphagia and VFMI in CS patients. We therefore sought to determine frequency of unsafe swallowing and VFMI before and after CS.
METHODS
Thirty-five adults undergoing elective CS enrolled. Participants underwent fiberoptic endoscopic evaluations of swallowing and VFMI before and after surgical procedure. Trained raters performed duplicate, blinded ratings with the validated Penetration-Aspiration Scale, and a laryngologist performed blinded ratings of VFMI. Descriptive, Wilcoxon signed rank, and McNemar tests were performed.
RESULTS
Preoperative swallowing safety profiles were 60% safe, 34% penetration, and 6% aspiration. Postoperative swallowing safety profiles were 14% safe, 63% penetration, and 23% aspiration. Significant differences in preoperative to postoperative swallowing outcomes were noted for Penetration-Aspiration Scale scores ( < .0001), unsafe swallowing (40% vs 86%; χ = 12.8; = .0003), and aspiration (6% vs 23%; χ =6; = .01). No differences in VFMI were noted preoperatively to postoperatively (partial VFMI, 9% vs 23%; > .05).
CONCLUSIONS
A 4-fold increase in aspiration was observed in CS patients. No cases of vocal fold paralysis were observed across time points. These data highlight the utility of instrumental laryngoscopic evaluations during the acute postoperative phase.

OBJECTIVE
To systematically review vagus nerve stimulation (VNS) studies to present data on the safety and efficacy on motor recovery following stroke, traumatic brain injury (TBI), and spinal cord injury (SCI).
METHODS
Data sources: PubMed, EMBASE, SCOPUS, and Cochrane.
STUDY SELECTION
Clinical trials of VNS in animal models and humans with TBI and SCI were included to evaluate the effects of pairing VNS with rehabilitation therapy on motor recovery.
DATA EXTRACTION
Two reviewers independently assessed articles according to the evaluation criteria and extracted relevant data electronically.
DATA SYNTHESIS
Twenty-nine studies were included; 11 were animal models of stroke, TBI, and SCI, and eight involved humans with stroke. While there was heterogeneity in methods of delivering VNS with respect to rehabilitation therapy in animal studies and human non-invasive studies, a similar methodology was used in all human-invasive VNS studies. In animal studies, pairing VNS with rehabilitation therapy consistently improved motor outcomes compared to controls. Except for one study, all human invasive and non-invasive studies with controls demonstrated a trend toward improvement in motor outcomes compared to sham controls post-intervention. However, compared to non-invasive, invasive VNS, studies reported severe adverse events such as vocal cord palsy, dysphagia, surgical site infection, and hoarseness of voice, which were found to be related to surgery.
CONCLUSION
Our review suggests that VNS (non-invasive or invasive) paired with rehabilitation can improve motor outcomes after stroke in humans. Hence, VNS human studies are needed in these populations (referring to SCI and TBI?) or just SCI. There are risks related to device implantation to deliver invasive VNS compared to non-invasive VNS. Future human comparison studies are required to study and quantify the efficacy vs. risks of paired VNS delivered via different methods with rehabilitation, which would allow patients to make an informed decision.

Esophageal diverticulum is a rare condition characterized by the herniation of the esophageal mucosa outside the esophageal wall. Here, we explore the prevalence of ED and its associated esophageal dysmotility. We also shed light on the potential impact of previous surgical interventions, such as Nissen's fundoplication, on the development of ED. This manuscript presents the case of a 72-year-old woman with a history of Nissen's fundoplication surgery who experienced worsening symptoms of dysphagia, heartburn and postprandial cough. Despite exhibiting a normal motility pattern, upper endoscopy revealed a large epiphrenic esophageal diverticulum. The patient underwent successful surgical resection with myotomy, resulting in the resolution of symptoms with no complications. This case highlights the rarity of symptomatic ED and the need to recognize it while choosing the optimal treatment modality.

BACKGROUND
This study aimed to compare the clinical outcomes of Zero-P and ROI-C devices applied to anterior cervical discectomy and fusion (ACDF) surgery of cervical degenerative disc disease (CDDD).
METHODS
From January 2020 and December 2020, 56 patients with CDDD who underwent ACDF using Zero-P or ROI-C were included in this retrospective study. The outcomes included visual analogue scale (VAS) score, Japanese Orthopedic Association (JOA) score, neck disability index (NDI) score, Cobb angle, dysphagia, and bone fusion rate. Dysphagia was assessed using the Bazaz grading system. The comparison of outcomes between the two groups was based on the 2-year follow-up time point, which was defined as the last follow-up visit.
RESULTS
The Zero-P group included 16 males and 14 females, with a mean age of 56.2 (range, 35-65) years. The ROI-C group included 11 males and 15 females, with a mean age of 57.4 (range, 36-67) years. There was no significant difference in gender and mean age between the two groups. There were no significant differences in VAS score, JOA score, NDI score, Cobb angle, dysphagia, and bone fusion rate between two groups at the last follow up visit. In the Zero-P group, the duration of surgeries involving C3-4 or C6-7 segments was significantly longer than those including C4-5 or C5-6 segments (135.0 ± 19.0 vs. 105.6 ± 17.5 min, < 0.05). In surgeries involving C3-4 or C6-7 segments, the operation time of ROI-C was significantly shorter than that of Zero-P (106.5 ± 19.5 vs.112.2 ± 20.5 min, < 0.05). There were no significant differences in the dysphagia or cage subsidence rates between the Zero-P and ROI-C groups ( > 0.05). The Cobb angle in the last follow-up visit in the Zero-P group (24.4 ± 4.5°) was significantly higher than that in the ROI-C group (18.1 ± 2.3°) ( < 0.05).
CONCLUSIONS
ACDF using ROI-C device showed an efficacy similar to the Zero-P device, as well as a shorter operation time for surgeries involving C3-4 or C6-7 segments. However, ROI-C could cause more loss of Cobb angle over time, which could lead to uncomfortable symptoms.

Achalasia is a rare esophageal motility disorder characterized by incomplete lower esophageal sphincter (LES) relaxation, increased LES tone, and absent peristalsis in the esophagus. Management of achalasia includes pneumatic dilation (PD), Botulinum toxin A (BTA) injections to LES, per oral endoscopic myotomy (POEM), and a laparoscopic Heller myotomy (LHM). Situs inversus is a rare congenital condition in which the abdominal and thoracic organs are located in a mirror image of the normal position in the sagittal plane. We herein present a case of a patient with Type II achalasia who underwent an LHM and toupet fundoplication in the setting of an isolated laterality malposition of the liver on the left side of the abdomen. Single organ congenital lateralization defects are extremely rare with literature describing few case reports and case series. A much rarer condition is isolated organ situs inversus. In the foregut, most reports of isolated situs inversus are limited to isolated gastric situs inversus, dextrogastria. Most isolated liver malposition has described situs ambiguous, at the midline, usually associated with polysplenia. Our patient had the normal position of the foregut structures, including the stomach, spleen, pancreas, and duodenum, except for the isolated situs inversus of the liver. Because of the unusual anatomy, performing an LHM was quite challenging. Our workup approach and intraoperative considerations are described. By displacing the larger left lobe of the liver, we were able to safely complete a standard heller myotomy with adequate length and distally across the gastroesophageal junction. Our patient had an uncomplicated post-operative course, and at follow-up has continued to show improvements in her dysphagia and her quality of life.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an uncommon genetic disorder that affects small blood vessels in the brain. It leads to neurological symptoms, disability-adjusted life years, and difficult emotional and physical situations for patients and their families. As unusual brain symptoms appear, it becomes important to understand the different clinical manifestations of CADASIL. Our case report and review examine several cases to demonstrate different presentations and management strategies of CADASIL. A 52-year-old male with a family history of strokes at a young age from his father and paternal grandfather presented to a neurology clinic for left facial droop and drooling. Brain magnetic resonance imaging showed extensive periventricular and subcortical white matter disease, including the external capsule and subcortical white matter of the temporal lobe. Findings were suggestive of small vessel vasculopathy. A cerebral angiogram showed that all large extra- and intracranial vessels were patent without evidence of aneurysm formation. There was no obvious evidence of beading of the distal intracranial vessels. Cerebrospinal fluid studies were normal. The NOTCH3 mutation was sent to test for CADASIL, which came back positive. The patient was started on aspirin (81 mg) and atorvastatin (20 mg) daily. The patient was counseled on the possibility of having an ischemic or hemorrhagic stroke. Aspirin and atorvastatin were continued, a neuropsychological evaluation was ordered, and CADASIL genetic counseling and testing were offered to him and his children. Over several years, patients developed several strokes and seizures due to infarcts. He also developed intraparenchymal hemorrhage complicated by dysphagia, requiring a feeding tube. Due to his severe physical debility, he was discharged to a nursing home for rehabilitation, where he did not improve with therapy and remained bedbound. He was discharged and sent home with his family. CADASIL can present as a diagnostic challenge due to its common presentation with migraines, transient ischemic attacks, and strokes, with or without risk factors. This unique presentation of CADASIL with facial palsy highlights the importance of emerging atypical presentations and the need for a detailed history of neuroimaging, family history, and personal history of neurovascular events. By accurately diagnosing the condition, patients and families can be counseled on the disease course and genetics. Management requires a multidisciplinary approach with neurology, genetic counseling, physical therapy, psychology, and psychiatry if depression or anxiety is present, with the aim of improving the patient's quality of life.
