Purpose: The current gold standard for the diagnosis of white-coat effect is by the 24-h ambulatory blood pressure monitoring (ABPM) which may not be readily available in every primary care setting. Previous studies had shown that deep breathing, through modulating the baroreceptor reflex sensitivity to vagal stimulation over 30 to 60 s, was useful in detection of the white-coat effect. The aim of our study was to evaluate the diagnostic accuracy of the deep breathing test (DBT) as compared with the gold standard of ABPM in the diagnosis of hypertension with white-coat effect in Chinese patients in primary care...

OBJECTIVE: Patients with electrical injury are considered to be at high risk of cardiac arrhythmias. Due to the small number of studies, there is no widely accepted guideline regarding the risk assessment and management of arrhythmic complications after electrical accident (EA). Our retrospective observational study was designed to determine the prevalence of ECG abnormalities and cardiac arrhythmias after EA, to evaluate the predictive value of cardiac biomarkers for this condition and to assess in-hospital and 30-day mortality...

CONTEXT: Surfer's myelopathy (SM) is an acute syndrome identified by nontraumatic paraparesis or paraplegia. Though traditionally tied to first-time surfers, the condition encompasses any activity involving hyperextension of the back such as gymnastics, yoga, and Pilates. METHODS: MEDLINE® and Google Scholar literature searches were gathered to identify relevant case reports for determining the etiology, pathogenesis, evaluation, and management of SM. RESULTS: While the rare nature of SM limits its full understanding, studies have pinpointed that hyperextension in the back leads to vasculature insufficiency secondary to dynamic compression of the artery of Adamkiewicz...

AIM: To explore the value of cough maneuver (CM) in detecting right-to-left (RLS) during contrast transthoracic echocardiography (cTTE) and its mechanism. METHOD: We enrolled 196 patients with a high level of clinical suspicion of RLS underwent cTTE for RLS detection. Valsalva maneuver (VM) (blowing into a face mask connected to a sphygmomanometer at 40 mm Hg for 10 seconds) and CM were performed to provoke RLS, respectively. A comparison of the two provocative maneuvers in terms of the RLS-detection rate, the degree of RLS, the mobility of septum primum was done...

INTRODUCTION: Sinus pericranii (SP) is a rare vascular anomaly consisting in an abnormal intradiploic communication between intra and extra cranial venous systems. It usually presents as a congenital soft mass in the cranial midline with progressive growth, which enlarges significantly with Valsalva maneuver. A similar congenital vascular anomaly involving intra and extra cranial arterial systems has not been previously described in the medical literature. CLINICAL CASE: A 6-year-old boy with suspected midline capillary malformation of the frontal bone was referred to our Vascular Anomalies Unit for progressive increase in size...

Sepsis is a leading cause of death in hospitalized patients. Many experimental treatments may have failed in clinical trials for sepsis, in part, because they focused on immune responses of healthy animals that did not mimic the metabolic settings of septic patients. Epidemiological studies show an association between metabolic and immune alterations and over 1/3 of septic patients are diabetic, but the mechanism linking these systems is unknown. Here, we report that metabolic fasting increased systemic inflammation and worsened survival in experimental sepsis...

PURPOSE: To evaluate mini-sling long-term results and correlate them to failure predictors. Many studies show comparable results among different single-incision slings developed as an attempt to reduce complications while keeping good results, but there is a lack of evidence about mini-slings outcomes in the long term. METHODS: This prospective, single-center study evaluated 40 patients for long-term outcomes after mini-sling placement. Objective cure was defined as leakage of less than 1 g in 1-hour pad-test and no leakage at Valsalva maneuver...

A positive family history of hypertension (+FH) is a risk factor for the future development of hypertension. Hypertension is associated with reductions in baroreflex sensitivity (BRS). Therefore, we hypothesized that young women with a +FH (n=12, 22±1 yrs, BMI 21±1 kg/m2, MAP 79±1 mmHg) would have lower BRS compared to young women without a family history of hypertension (-FH) (n=13, 22±1 yrs, BMI 21±1 kg/m2, MAP 77±2 mmHg, all P>0.05 between groups). Continuous measurements of muscle sympathetic nerve activity (MSNA), blood pressure, and electrocardiogram derived R-R interval were recorded at rest and during a Valsalva maneuver...

BACKGROUND: Internal jugular phlebectasia (IJP) is an uncommon entity with only about 100 reported cases and with very few available cases in the literature. The current case study is about a male trainee fighter pilot incidentally diagnosed to have IJP. With limited literary evidence, it was a complex task to predict the prognosis of IJP and its implications on fighter flying. CASE REPORT: In order to confirm the diagnosis, a preliminary study was carried out to find out the normal and expanded area of the internal jugular vein (IJV) of 30 volunteers...

PURPOSE: To describe four cases of varix of the vortex vein ampulla imaged with dynamic echography. METHODS: Observational case series of four patients with varix of the vortex vein ampulla diagnosed with ocular examination maneuvers such as digital pressure or Valsalva. Dynamic echography was used to confirm the diagnosis. RESULTS: Dynamic echography can quickly and noninvasively show the varix of the vortex vein ampulla disappear with external pressure, or engorge with a Valsalva maneuver or altered gaze directions...

BACKGROUND: Internal jugular venous thrombosis (IJVT) is an uncommon condition rarely diagnosed in the outpatient setting. IJVT carries significant morbidity and mortality and must be considered in the differential diagnosis for new-onset neck pain and swelling, especially in the emergency setting. Paget-Schroetter syndrome (PSS), or primary thrombosis secondary to effort, is an uncommon, likely under-recognized etiology of thrombosis. We report a case of PSS extending from the right subclavian vein into the right internal jugular vein, suspected based upon patient history and physical examination and confirmed by point-of-care ultrasound (POCUS)...

AIM: To examine the position of the TVT-O sling 10 years postoperatively and its association with outcome. METHODS: A total of 124 patients who received a TVT-O sling at two centers in 2004 and 2007 were invited for follow-up. The position of the sling on perineal ultrasound was described relative to the bladder neck and the lower margin of the pubic symphysis at rest and on Valsalva. Objective cure was defined as a negative cough stress test at 300 ml. Subjective cure was evaluated with the Kings´ Health Questionnaire (KHQ), Incontinence Outcome Questionnaire (IOQ), Female Sexual Function Index Questionnaire (FSFI) and the Patient Global Impression of Improvement score (PGII)...

Endotracheal intubation, a common procedure in neonatal intensive care, results in distress and disturbs physiologic homeostasis in the newborn. Analgesics, sedatives, vagolytics, and/or muscle relaxants have the potential to blunt these adverse effects, reduce the duration of the procedure, and minimize the number of attempts necessary to intubate the neonate. The medical care team must understand efficacy, safety, and pharmacokinetic data for individual medications to select the optimal cocktail for each clinical situation...
