BACKGROUND: The Eustachian tube (ET) has a major role in the middle ear (ME) pressure homeostasis. ET dysfunction is the accepted paradigm for pressure-related ME disorders. We studied the ME status in patients with severely diminished ET opening abilities, and anticipated to find ME disorders in most of them. PATIENTS AND METHODS: ME status was evaluated in unconscious adults, who were hospitalized in a rehabilitation center with severe brain damage, requiring tracheotomy and gastrostomy...

BACKGROUND: Inguinal hernia is a commonly encountered cause of pain in athletes. Because of the anatomic complexity, lack of standard imaging, and the dynamic condition, there is no unified opinion explaining its underlying pathology. HYPOTHESIS: Athletes with persistent groin pain would have a high prevalence of inguinal hernia with dynamic ultrasound, and herniorrhaphy would successfully return athletes to activity. STUDY DESIGN: Case-control study...

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...

We developed an intravaginal instrumented probe (covered with a 10×10 matrix of capacitive sensors) for assessing the three-dimensional (3D) spatiotemporal pressure profile of the vaginal canal. The pressure profile was compared to the pelvic floor (PF) digital assessment, and the reliability of the instrument and repeatability of the protocol was tested. We also tested its ability to characterize and differentiate two tasks: PF maximum contraction and Valsalva maneuver (maximum intra-abdominal effort with downward movement of the PF)...

Vaginal delivery is commonly accepted as a risk factor in pelvic floor dysfunction; however, other obstetric procedures (episiotomy) are still controversial. In this work, to analyze the relationship between episiotomy and pelvic floor function, a finite element model of the pelvic cavity is used considering the pelvic floor muscles (PFMs) with damaged regions from spontaneous vaginal delivery and from deliveries with episiotomy. Common features assessed at screening of pelvic floor dysfunction are evaluated during numerical simulations of both Valsalva maneuver and contraction...

OBJECTIVE: There is no agreement on the best clinical test for Eustachian tube (ET) dysfunction. Numerous tests have been developed to detect ET opening, and all require a patient to perform a Valsalva, Toynbee or sniff maneuver, or to swallow on demand. We aimed to characterize existing tests of ET function in healthy ears, and identify the optimal method and patient maneuver for each test. Our own normative data is presented alongside published comparisons. STUDY DESIGN: Diagnostic test cohort study...

OBJECTIVES/HYPOTHESIS: Many objective tests of eustachian tube (ET) function have been devised for clinical and research use but they have not been directly compared or characterized. As a first step to identifying tests to incorporate into an outcome set for ET dysfunction, we assessed repeatability of a panel of eight of these tests in healthy ears. STUDY DESIGN: Comparison of eight tests of ET function. METHODS: The following tests were investigated in combination with Valsalva, Toynbee, swallow, or sniff maneuvers: 1) patient-reported ET opening, 2) observed tympanic membrane movement, 3) continuous impedance, 4) canal manometry, 5) sonotubometry, 6) nine-step test, 7) tubomanometry, and 8) tympanometry at rest...

BACKGROUND: Compulsive movements, complex tics and stereotypies are frequent, especially among patients with autism or psychomotor retardation. These movements can be difficult to characterize and can mimic other conditions like epileptic seizures or paroxysmal dystonia, particularly when abnormal breathing and cerebral hypoxia are induced. CASE PRESENTATION: We describe an 18-year-old patient with Asperger syndrome who presented with attacks of tonic posturing of the trunk and neck...

BACKGROUND: Imaging the Eustachian tube has proven difficult as it has an anatomical orientation that is not aligned with standard planes. In addition, the Eustachian tube is a dynamic structure, opening briefly during a variety of physiological manoeuvres. CASE REPORT: A 54-year-old healthy and asymptomatic man underwent computed tomography utilising an area detector scanner. Multiplanar reconstruction was performed at 1 mm intervals. In addition, dynamic clips were constructed to demonstrate air and its movement in the field...

A 69-year-old man underwent minimal incision mitral valve repair for severe symptomatic mitral regurgitation. The echocardiography showed that he had normal left ventricular function with a moderately to severely dilated left atrium, a mildly dilated right atrium, and a large patent foramen ovale. The multistage venous cannulation was very challenging because we could not negotiate the guide wire from the inferior vena cava via the right atrium into the superior vena cava. Despite several attempts, the guide wire would pass into the patent foramen ovale...

Acromegaly is a rare disease, mostly caused by a growth hormone (GH)-secreting benign pituitary tumor, with an increased production of GH and insulin-like growth factor 1 (IGF-1). Cardiovascular complications are common and are associated with cardiomyocyte apoptosis and concentric cardiac hypertrophy. Suppression of GH and IGF-1 appears to improve cardiac function only in the short term, with little or no decrease in left ventricular mass or improvement in cardiac function after prolonged treatment. Alcohol septal ablation (ASA) has emerged as a minimally invasive alternative to septal myectomy, with significant improvement in symptoms, gradients and left ventricular remodeling...

BACKGROUND: The working posture affects the peripheral venous circulation, although the current literature does not report any correlation between working posture and the abnormalities of the jugular veins flow. The purpose of this preliminary research is to study, in female workers, the prevalence of Venous Compressive Syndrome (VCS) caused by total block of the internal jugular veins flow, so-called "White Compression". Due to complete compression by postural, muscular, fascial, anatomical or bone anomalies, White Compression is not visible by EchoColorDoppler (ECD) and its flow can only be detected by the rotational movements of the head or by Valsalva's maneuver...

BACKGROUND: Development of left ventricular outflow tract obstruction (LVOTO) in patients with hypertrophic cardiomyopathy (HCM) is important for explaining symptoms and designing management. LVOTO is mostly caused by a combination of septal hypertrophy and systolic anterior movement of the mitral valve (SAM). The aim of the present study was to determine predictors of exercise induced LVOTO in a group of HCM patients. METHODS: We performed supine exercise Doppler echocardiography, including measurements of LV morphology and function and anterior mitral leaflet length, in 51 mildly symptomatic HCM (septal thickness≥15mm) and compared them with 50 healthy controls...

BACKGROUND: Stress urinary incontinence (SUI), the most common type of urinary incontinence (UI), is usually defined as leakage of urine during movement or activity which puts pressure on the bladder, such as coughing, sneezing, running or heavy lifting. It is reported in most countries that 15% to 40% of women struggle with SUI and its severe implications for daily life, including social interactions, sexuality, and psychological wellbeing. OBJECTIVES: The aim of our study was to assess the relationship between urinary tract infection and the severity of stress urinary incontinence (SUI)...
