Major depression disorder (MDD) patients express dysfunction autonomic nervous system (ANS) and reduced heart rate variability (HRV). However, previous researches mainly focused on examining resting state without considering a series of stimulation tests of ANS between MDD patients and healthy people. For this purpose, 40 healthy people and 40 MDD patients participated and finished 10min clinical autonomic test-Ewing test. Parameters of HRV such as time domain, frequency domain, and nonlinear dynamical parameters were calculated...

OBJECTIVES: Dot-like hippocampal hyperintensities (HHs) on diffusion-weighted MRI (DWI) have been reported as an interesting imaging finding of transient global amnesia (TGA) that is characterized by typical anterograde amnesia. However, we found that these dot-like HHs are occasionally seen in some patients without clinical symptoms of TGA. METHODS: We identified 8 patients who did not show clinical symptoms of TGA, despite the presence of hippocampal lesions on DWI (No-TGA group, n=8)...

We present two cases of Amplatzer® device deployment that exhibited long-term failure necessitating surgical correction. The first case illustrates recanalization of a ruptured Valsalva aneurysm with worsening aortic insufficiency after percutaneous repair with the Amplatzer Vascular Plugs and Amplatzer duct occluder, while the second case illustrates recanalization after deployment of the Amplatzer septal occluder in a patient with a pseudoaneursym in a bovine aorta after type I aortic dissection repair. These two cases illustrate the potential long-term complications and limitations in durability with these devices...

INTRODUCTION: Autonomic disorders have been recognized as important Parkinson's disease (PD) components. Some vulnerable structures are related to the central autonomic network and have also been linked to autonomic function alterations. The aims of the study are to evaluate the severity of the autonomic dysfunction and the cortical hypoperfusion using arterial spin labeling (ASL) MRI. And then, possible relationships of significant between-group differences in perfusion pattern to clinical variables and autonomic functions were examined to determine the pharmaceutical effects of dopaminergic treatment on cerebral blood flow (CBF) in patients with PD...

A 28-year-old female diver presented with dizziness and difficulty clearing her left ear whilst scuba diving. Her pure-tone audiometry and tympanometry were normal. Testing of Eustachian tube function revealed tubal stenosis. Video-oculography revealed a predominantly torsional nystagmus while the patient was in the lordotic position. Fistula signs were positive. High-resolution computed tomography (HRCT) of the temporal bone revealed a diagnosis of bilateral superior semicircular canal dehiscence (SCDS). Cervical vestibular-evoked myogenic potential (cVEMP) testing showed that the amplitude of the cVEMP measured from her left ear was larger than that from the right...

BACKGROUND: Enlargement of the proximal aorta is associated with aortic wall tissue remodeling, including fragmentation of the elastin fibers, increased synthesis of collagen, and calcification, all of which are associated with aortic wall stiffening. We hypothesized that the proximal aortic diameter (AoD) is associated with cardiovascular events in a community-based cohort of blacks. METHODS AND RESULTS: We investigated the associations between AoD and cardiovascular events among 3018 black participants (mean age, 55...

Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, which mostly occurs in the right or noncoronary sinus of Valsalva. Left sinus of Valsava is infrequent. Unruptured SVAs are usually asymptomatic, and the diagnosis of unruptured SVA is usually accidental. A giant unruptured SVA may compress the coronary artery and cause myocardial infarction. Here, we report a rare case of a 50-year-old patient with unruptured giant left SVA causing occlusion of the left anterior descending coronary artery, which was successfully managed with our apparently unique surgical procedure...

INTRODUCTION AND HYPOTHESIS: There is a lack of epidemiological studies evaluating female pelvic organ prolapse in developing countries. Current studies have largely focused on women of white ethnicity. This study was designed to determine interethnic variation in pelvic floor functional anatomy, namely, levator hiatal distensibility and pelvic organ descent, in women with symptomatic pelvic organ prolapse in a multi-ethnic South African population. METHODS: This prospective observational study included 258 consecutive women referred for pelvic organ prolapse assessment and management at a tertiary urogynaecological clinic...

The clinical evaluation of patients with an anomalous aortic origin of a coronary artery (AAOCA), a congenital abnormality of the origin or course of a coronary artery that arises from the aorta, is challenging given its first presentation being sudden cardiac arrest in about half of the patients. Symptoms of chest pain, shortness of breath and syncope during exertion should be of concern in evaluating young athletes and nonathletes. The lack of abnormal signs on the physical exam and electrocardiogram further adds to the difficulty in establishing the diagnosis...

Rupture of right sinus of Valsalva aneurysm (SVA) protruding into the pulmonary artery with aortic and pulmonary valve endocarditis is rare. A 42-year-old man was admitted with fever and dyspnea. He was diagnosed with right sinus of Valsalva rupture with ventricular septal defect (VSD) and vegetation on both aortic and pulmonary valves. Dual exposure technique was performed. The base of the aneurysm sac was closed off, and, together with the VSD, was covered by a Gore-Tex patch. Aortic and pulmonary valves were replaced with mechanical valves...

Background: Exaggerated beat-to-beat variability of ventricular action potential duration (APD) is linked to arrhythmogenesis. Sympathetic stimulation has been shown to increase QT interval variability, but its effect on ventricular APD in humans has not been determined. Methods and Results: Eleven heart failure patients with implanted bi-ventricular pacing devices had activation-recovery intervals (ARI, surrogate for APD) recorded from LV epicardial electrodes under constant RV pacing. Sympathetic activity was increased using a standard autonomic challenge (Valsalva) and baroreceptor indices were applied to determine changes in sympathetic stimulation...

Background Reversible cerebral vasoconstriction syndrome (RCVS) is an important differential diagnosis of singular or recurrent thunderclap headache. Prognosis is generally good, however complications of the transient segmental vasospasms of cerebral arteries such as stroke, subarachnoidal hemorrhage and brain edema may worsen the clinical outcome. Although the exact pathomechanism is still unclear, various vasoactive substances and conditions (e.g. post partum) have been identified as triggering RCVS. Cases We report on the clinical course and management of two cases of typical RCVS that were associated with two different precipitants previously not described: A gastrointestinal infection and isoflavones, which are phytoestrogens used for menopausal vasomotor symptoms...

Objectives: Eustachian tube dysfunction has been associated with most cases of middle-ear disease. We aimed to assess the effectiveness of dynamic slow motion video endoscopy (DSVE) as a test of eustachian tube dysfunction. Furthermore, we assessed the correlation of the test with the Valsalva maneuver, the seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7), and intraoperative findings of the eustachian tube. Methods: We retrospectively reviewed medical records from April to September 2014 to identify patients who were diagnosed with chronic otitis media (COM) at Korea University Ansan Hospital...

PURPOSE: To evaluate the effect of the Valsalva maneuver (VM) on anterior segment parameters and its association with refractive status. METHOD: In this prospective study, 120 eyes of 120 subjects were evaluated. Subjects were divided into three groups: myopic (n = 40 patients), hyperopic (n = 40 patients), and emmetropic (control group, n = 40 subjects). The anterior segment parameters, including keratometric, pachymetric, and anterior chamber parameters, were measured using the Sirius System (Costruzione Strumenti Oftalmici, Florence, Italy) before and during VM...

OBJECTIVE: In patients presenting with aortic valvulopathy with concomitant ascending aortic aneurysm, surgical management of the sinus of Valsalva segment remains undefined, especially for moderately dilated aortic roots. In patients with this pathology undergoing aortic valve replacement with supracoronary ascending aorta replacement, we assessed the fate of the remnant preserved sinus of Valsalva segment stratified by aortic valve morphology and pathology. METHODS: From 2002 to 2015, 428 patients underwent elective aortic valve replacement with supracoronary ascending aorta replacement...

AIMS: To analyze whether episiotomy affects the urogenital hiatal area and the difference in the hiatus at rest and during contraction, as an indirect measurement of the contractile capacity of the levator ani muscle. METHODS: We performed an observational, comparative, retrospective study of primiparous women who had normal vaginal deliveries. The urogenital hiatal area was compared in women with and without episiotomy. All women underwent transperineal ultrasound scanning after delivery, and all the images were analyzed offline by the principal investigator who was blinded to all clinical data...

RATIONALE: Ruptured aneurysm originating from the left coronary sinus of Valsalva into the left ventricle (LV) is extremely rare. Imaging features of sinus aneurysm has been commonly reported using echocardiography or angiography. Here, we report multidetector computed tomography (MDCT) findings of left sinus of Valsalva aneurysm extending into the LV and caused severe aortic regurgitation (AR) in a 44-year-old male with latent infective endocarditis. The role of MDCT in preoperative surgical planning was also emphasized...
