Objectives:
. Balloon dilation of the Eustachian tube (BDET) is widely recognized as a minimally invasive treatment for obstructive Eustachian tube dysfunction (ETD). We employed a Delphi consensus methodology to develop recommendations for the clinical management of BDET in cases of obstructive ETD.
Methods:
. A Delphi panel consisting of 26 expert physicians specializing in otology participated in two rounds of anonymous, iterative questionnaires. Consensus was defined as agreement from ≥70% of the panelists on a recommendation, while disagreement was defined as <70% agreement. The responses from the Delphi study were analyzed using both the content validity ratio and Kendall’s coefficient of concordance.
Results:
. The panel finally evaluated 26 topics, reaching agreement on 9 and failing to reach consensus on 17 after two rounds. While consensus was not achieved regarding the postoperative follow-up period, a duration of 12 months was most commonly adopted. The Valsalva maneuver and questionnaire responses were identified as the most agreed-upon postoperative assessment tools following BDET.
Conclusion
. Consensus was reached on several recommendations for managing BEDT in obstructive ETD. This agreement will guide future research aimed at defining standard postoperative management for BEDT.

Purpose:
Since diabetes and hypertension frequently occur together, it is thought that these conditions may have a common pathogenesis. This study was designed to evaluate the anti-diabetic function of the anti-hypertensive drug fimasartan on C2C12 mouse skeletal muscle and HepG2 human liver cells in a high glucose state.
Materials and Methods:
The anti-diabetic effects and mechanism of fimasartan were identified using Western blot, glucose uptake tests, oxygen consumption rate (OCR) analysis, adenosine 5'-triphosphate (ATP) enzyme-linked immunosorbent assay (ELISA), and immunofluorescence staining for diabetic biomarkers in C2C12 cells. Protein biomarkers for glycogenolysis and glycogenesis were evaluated by Western blotting and ELISA in HepG2 cells.
Results:
The protein levels of phosphorylated 5' adenosine monophosphate-activated protein kinase (p-AMPK), p-AKT, insulin receptor substrate-1 (IRS-1), and glucose transporter type 4 (Glut4) were elevated in C2C12 cells treated with fimasartan. These increases were reversed by peroxisome proliferator-activated receptor delta (PPARδ) antagonist. ATP, OCR, and glucose uptake were increased in cells treated with 200 μM fimasartan. Protein levels of glycogen phosphorylase, glucose synthase, phosphorylated glycogen synthase, and glycogen synthase kinase-3 (GSK-3) were decreased in HepG2 cells treated with fimasartan. However, these effects were reversed following the addition of the PPARδ antagonist GSK0660.
Conclusion
In conclusion, fimasartan ameliorates deteriorations in glucose metabolism as a result of a high glucose state by regulating PPARδ in skeletal muscle and liver cells.

Background:
Obesity, the prevalence of which is increasing due to the lack of exercise and increased consumption of Westernized diets, induces various complications, including ophthalmic diseases. For example, obesity is involved in the onset of cataracts.
Methods:
To clarify the effects and mechanisms of midodrine, an α1-adrenergic receptor agonist, in cataracts induced by obesity, we conducted various analytic experiments in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a rat model of obesity.
Results:
Midodrine prevented cataract occurrence and improved lens clearance in OLETF rats. In the lenses of OLETF rats treated with midodrine, we observed lower levels of aldose reductase, tumor necrosis factor-α, and sorbitol, but higher levels of hexokinase, 5’-adenosine monophosphate-activated protein kinase-alpha, adenosine 5´-triphosphate, peroxisome proliferator-activated receptordelta, peroxisome proliferator-activated receptor gamma coactivator 1-alpha, superoxide dismutase, and catalase.
Conclusion
The ameliorating effects of midodrine on cataracts in the OLETF obesity rat model are exerted via the following three mechanisms: direct inhibition of the biosynthesis of sorbitol, which causes cataracts; reduction of reactive oxygen species and inflammation; and (3) stimulation of normal aerobic glycolysis.

Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a distinct subset of cerebral amyloid angiopathy characterized by the auto-inflammatory response to amyloid-laden small arteries of cerebral cortex and leptomeninges. Clinical features include cognitive-behavioral change, headache, focal neurologic deficits and seizure. Because anti-inflammatory treatments can rapidly relieve neurologic symptoms, early diagnosis is critical. Herein, we report a CAA-RI case with distinct laboratory findings of a decreased cerebrospinal fluid amyloid beta 1-42 level and relatively reduced florbetaben uptake in the focal inflammatory lesion during the acute phase of CAA-RI.

The intrinsic structural failure of a Dacron graft resulting from the loss of structural integrity of the graft fabric can cause late graft complications. Late non-anastomotic rupture has traditionally been treated surgically via open thoracotomy. We report a case of the successful use of thoracic endovascular repair to treat a Dacron graft rupture in the descending aorta. The rupture occurred 20 years after the graft had been placed. Two stent grafts were placed at the proximal portion of the surgical graft, covering almost its entire length.

Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by the calcification and ossification of soft tissue, and can lead to severe cervical kyphosis, presenting with a spectrum of physical complaints including dysphagia, hoarseness, stridor, aspiration pneumonia, and dyspnea due to airway compromise. Restrictive ventilatory impairment is very rare. We encountered a 73-year-old man with DISH presenting with progressive dysphagia and dyspnea over a few months. The symptoms were evaluated with a video fluoroscopy swallowing study and pulmonary function tests (PFT). The PFT revealed restrictive ventilatory impairment. A neck magnetic resonance imaging (MRI) study showed anterior cervical osteophytes causing upper airway compromise and compression of the esophagus. Osteophytes were removed surgically and the patient improved clinically. Here, we describe the case with a literature review.

Apical ballooning syndrome (ABS), also referred to as stress cardiomyopathy, is characterized by acute left ventricular dysfunction following a stressful situation. Diagnosis of ABS is made in the following scenarios: transient hypokinesia or dyskinesia of the left ventricular segment, absence of obstructive coronary disease, new electrocardiogram abnormalities, absence of recent significant head trauma, pheochromocytoma, myocarditis, and hypertrophic cardiomyopathy. Prognosis is usually favorable since the wall motion abnormality returns to normal within days, and certainly within the first month. We encountered a case of SLE with apical ballooning on echocardiography in a 44-year-old woman. She was suffering from severe left ventricular dysfunction that has persisted on 5 year follow-up echocardiography. We report this case along with a review of the relevant literature.
