OBJECTIVE: In distinguishing urate arthritis (UA) from non-crystal-related arthritides, joint sonography including the detection of the double contour sign (DCS) and hypervascularization using power Doppler ultrasound (PDUS) is an important step in the diagnostic process. But are these sonographic features equally reliable in every accessible joint under real-life conditions? METHODS: We retrospectively analyzed 362 patients with acute arthritis and evaluated the DCS and the degree of PDUS hypervascularization in patients with gout and in those with arthritis other than urate arthritis (non-UA)...

Prenatal, neonatal meningoencephalitis and infections of the brain in older infants are often associated with serious complications which can be diagnosed by sonography through the open fontanelles. Most frequently postmeningitic hydrocephalus and subdural effusions occur. Rarer complications are brain abscesses and ventriculitis which are caused by gram negative bacteria such as E. coli, Serratia marcescens, Proteus and Enterobacter. A serious complication after ventriculitis is the development of compartment hydrocephalus...

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease worldwide and is potentially treatable, though there are few therapeutic agents available. Artichoke leaf extract (ALE) has shown potential as a hepatoprotective agent. This study sought to determine if ALE had therapeutic utility in patients with established NAFLD. In this randomized double-blind placebo-controlled parallel-group trial, 100 subjects with ultrasound-diagnosed NAFLD were randomized to either ALE 600 mg daily or placebo for a 2-month period...

A 40-year-old retired male elite athlete with more than 20 years' experience in wrestling and bodybuilding with mild elbow pain and disability of 2 years presented to our clinic reporting an acute pain in medial aspect of the elbow. Physical examination revealed symptoms of left Golfer's elbow during target-directed movements. The results of sonography in left elbow showed low level of hypo echo irregularity and increased blood flow in color Doppler mode in the common flexor origin. The pain amplitude was moderate at rest and extremely high during kinetic and intentional movements...

OBJECTIVE:  Practical deficiencies related to conventional transcranial Doppler (TCD) sonography have restricted its use and applicability. This work seeks to mitigate several such constraints through the development of a wearable, electronically steered TCD velocimetry system, which enables noninvasive measurement of cerebral blood flow velocity (CBFV) for monitoring applications with limited operator interaction. MATERIALS AND METHODS: A highly-compact, discrete prototype system was designed and experimentally validated through flow phantom and preliminary human subject testing...

BACKGROUND: Postoperative neurological injury still represents a major cause of morbidity after cardiac surgery. Our objective was to compare the limits as well as advantages of routine monitoring tools for the detection of cerebral function and perfusion deficits during cardiopulmonary bypass in a daily clinical setting. METHODS: Adult patients undergoing elective cardiac surgery with use of cardiopulmonary bypass were included. Patients received monitoring comprising Bispectral Index (BIS), Near Infrared Spectroscopy (NIRS) and assessment of middle cerebral artery flow velocity (MCAV) using transcranial Doppler (TCD) sonography...

Testicular sonography has contributed greatly to the preoperative diagnosis of testicular torsion in the pediatric patient and is the mainstay for evaluation of acute scrotal pain. Despite its high sensitivity and specificity, both false-negative and false-positive findings occur. Presence of documented Doppler flow within the testis might be a dissuading factor for surgical exploration with resultant testicular loss in the false-negative cases. Our goal is to illustrate key sonographic features in the spectrum of testicular torsion with preserved testicular flow, and to describe how to differentiate testicular torsion from epididymitis in order to avoid the under-diagnosis of testicular torsion...

INTRODUCTION: There are many techniques to identify vessels in perforator surgery, each with specific disadvantages. Handheld Dopplers are easy to use, but inaccurate with respect to the exact localisation of the perforator. Angio-CT is invasive, time consuming, and expensive. In contrast, duplex sonography is a reliable, easy-to-use and availabe alternative for pre-, intra-, and postoperative visualisation of vessels. Power Doppler further increases sensitivity and allows visualisation of vessels smaller than 0...

Herein we report a case of a 38-year-old men who presented with acute suprapubic pain caused by a tubular, hypoechoic, non-compressible, inguinal mass with no flow evident on color Doppler sonography. The history of the patient, the clinical signs of local inflammation and tenderness on palpation as well as the results of the Doppler ultrasound examination led to the diagnose of an inguinal hernia with bowl incarceration. However, due to a remaining uncertainty whether a bilateral or unilateral hernia was immanent and whether the bowl incarceration was caused by a right or left sided hernia the on-call surgeon initiated a computed tomography (CT) scan...

Disorders of the long head of the biceps tendon (LHBT) are a common source of shoulder pain and disability. This tendon can be well visualized using ultrasonography; however, little is known if such examination allows clinicians to predict pathological changes of the tendon structure. In the study described below, we compare preoperative sonographic findings with the data from shoulder arthroscopy and microscopic examination of the excised tendon fragments in 19 consecutive patients with LHB tendinopathy and clinical suspicion of its instability...

Psoriasis is one of the most common chronic inflammatory skin diseases, characterized by erythema and the formation of plaques. The diagnosis of psoriasis is based on clinical examination, and its severity is assessed by the Psoriasis Area and Severity Index. Histologic examination is still the standard method for the final diagnosis. Sonography has proved to be a suitable noninvasive imaging method for studying soft tissue in dermatologic diseases such as psoriasis. This study evaluated the effect of Doppler sonography in the assessment of psoriasis in comparison with histopathology...

Non-selective beta-blockers are the mainstay of medical therapy for portal hypertension in liver cirrhosis. Inhibitors of phosphodiesterase-5 (PDE-5-inhibitors) reduce portal pressure in the acute setting by > 10% which may suggest a long-term beneficial effect. Currently, there is no available data on long-term treatment of portal hypertension with PDE-5-inhibitors. This case of a patient with liver cirrhosis secondary to autoimmune liver disease with episodes of bleeding from esophageal varices is the first documented case in which a treatment with a PDE-5-inhibitor for eight years was monitored...

Splenic artery pseudoaneurysm (SAPA) is a relatively infrequently encountered but clinically important vascular change, because it carries a high risk of rupture that warrants prompt treatment regardless of its size. Thus, sufficient knowledge is indispensable when seeing chronic pancreatitis patients or post-traumatic patients. Here, we report two such cases. The first case was a 52-year-old woman known to have chronic pancreatitis who presented with hematemesis and hemodynamic instability in which X-ray computed tomography (CT) and color Doppler sonography (CDS) had difficulty visualizing slow blood flow in SAPA, but superb microvascular imaging (SMI) clearly demonstrated the slow blood flow in SAPA, prompting our therapeutic decision to perform rapid embolization...
