Solitary fibrous tumor is a rare neoplasm of mesenchymal origin that usually affects the pleura. This rarity becomes more relevant in the oral cavity since the clinical features are nonspecific. A 66-year-old female patient presented with a 3-month history of a swelling in the floor of the mouth, measuring 2 cm in greatest diameter, and pain symptomatology. Occlusal and panoramic radiographs showed no bone involvement. Ultrasonography of the submandibular and parotid salivary glands revealed normal morphology, dimensions, and echogenicity...

BACKGROUND AND STUDY AIMS: There is a lack of studies on erectile dysfunction (ED) in patients diagnosed with nonalcoholic fatty liver disease (NAFLD). The present study aimed to estimate the prevalence of ED in patients with NAFLD and to determine the independent predictors of ED in these patients. PATIENTS AND METHODS: We conducted a prospective, hospital-based study of 192 consecutive male patients with NAFLD. All patients underwent clinical evaluation; abdominal ultrasonography; test for viral hepatitis markers; and estimation of liver chemistry panel, complete blood count, prothrombin time, serum lipids panel, serum testosterone, and fasting serum levels of glucose, insulin, and C-peptide...

T Apard, G Candelier
The central slip tenotomy described by Fowler is an effective option for treating chronic mallet finger in order to avoid swan neck deformity of the finger. In a prospective study of 14 cases (13 failures of conservative treatment and one case of untreated mallet finger), we performed percutaneous ultrasound-guided central slip tenotomy with a 19 G needle using the wide-awake local anesthesia and no tourniquet (WALANT) technique. The mean extensor lag before surgery was 28° (range 20°-40°) and three patients had a swan neck deformity...

Jose D Tafur, Christopher J White
Atherosclerotic renal artery stenosis is the leading cause of secondary hypertension; it can also cause progressive renal insufficiency and cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid lowering agents, and antiplatelet therapy is the first line of treatment in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe renal artery stenosis are likely to benefit from renal artery revascularization...

BACKGROUND: Early diagnosis of acute mesenteric ischemia (AMI) based on clinical judgment has been proved to be too difficult. Therefore, it is important for identifying clinical parameters that can differentiate AMI from other acute abdomen upon presentation. METHODS: We analyzed a database of 106 consecutive patients admitted to the emergency ward for suspected AMI in whom diagnosis of AMI was confirmed by laparotomy, CT angiography or mesenteric angiography. The patients' demographics, previous history, clinical signs, results of laboratory investigations and ultrasonography were collected...

BACKGROUND: A moderate insufflation pressure and deep neuromuscular blockade (NMB) have been recommended in laparoscopic surgery in consideration of the possible reduction in splanchnic perfusion due to the CO2-pneumoperitoneum. Since the liver is the major organ for rocuronium metabolism, the question of whether NMB of rocuronium would change with the variation of liver perfusion during pneumoperitoneum during laparoscopic surgery merits investigation. METHODS: In this prospective study, a total of sixty female patients scheduled for either selective laparoscopic gynaecological surgery (group laparoscopy) or laparotomy for gynaecological surgery (group control) were analyzed...

Perianal disease, most commonly manifest as fistula or abscess formation, affects up to 40% of patients with Crohn's disease. Perianal Crohn's disease is disabling, associated with poor outcomes, and represents a therapeutic challenge for physicians. Correct diagnosis and classification of perianal disease is the first crucial step for appropriate multidisciplinary management. Areas covered: A literature search was performed of the PubMed database using the terms "transperineal ultrasonography", "transperineal ultrasound", "perianal disease", "perianal fistula", "perianal abscess", "magnetic resonance", "endoanal ultrasonography", "endoscopic ultrasound" in combination with "Crohn's disease"...

A 12-year-old girl presented with talipes equinus of both legs, attenuation of upper and lower limb tendon reflexes, thermal hyperalgesia, and reduction of vibratory sensation. On clinical examination, muscle twitches of fingers of both hands, as well as the abductor halluces and the dorsal interossei muscles of the right foot were observed. Nerve conduction velocity was significantly declined in the upper and lower extremities. Needle electromyography (EMG) was not performed; however, ultrasonography revealed repetitive, semi-regular muscle twitches lasting 0...

BACKGROUND: Carotid intima-media thickness (IMT) and plaque are recognized markers of increased risk for cerebrovascular events. Accurate visualization of the IMT and plaques is dependent upon image quality. Ultrasound contrast agents improve image quality during echocardiography-this study assessed whether contrast-enhanced ultrasound (CEUS) improves carotid IMT visualization and plaque detection in an asymptomatic population. METHODS & RESULTS: Individuals free from known cardiovascular disease, enrolled in a community study, underwent B-mode and CEUS carotid imaging...

A 5-y-old female ferret (Mustela putorius furo) was evaluated for diarrhea, anorexia, and lethargy for 1 wk. Only mild dehydration was detected on physical examination. CBC analysis revealed marked erythrocytosis with an unremarkable plasma biochemistry panel; follow-up CBC analyses revealed a consistent primary erythrocytosis. Whole-body radiographs and abdominal ultrasonography were unremarkable except for a small nephrolith in the right kidney and a small cyst in the left kidney. The plasma erythropoietin level was 17...

OBJECTIVE For a diagnosis of brain death (BD), ancillary testing is performed if patient factors prohibit a complete clinical examination and apnea test. The American Academy of Neurology (AAN) guidelines identify cerebral angiography (CA), cerebral scintigraphy, electroencephalography, and transcranial Doppler ultrasonography as accepted ancillary tests. CA is widely considered the gold standard of these, as it provides the most reliable assessment of intracranial blood flow. CT angiography (CTA) is a noninvasive and widely available study that is also capable of identifying absent or severely diminished intracranial blood flow, but it is not included among the AAN's accepted ancillary tests because of insufficient evidence demonstrating its reliability...

Technical advances are rapidly changing the clinical and instrumental approach to peripheral nerve diseases. Magnetic resonance neurography, diffusion tensor imaging and nerve ultrasonography are increasingly entering the diagnostic workup of peripheral neuropathies as tools that complement neurophysiology and enable investigation of proximal structures, such as plexuses and roots. Progress in the design of magnetic resonance scanners and sequences, and the development of high-frequency ultrasound probes mean that high-resolution peripheral nerve imaging is possible, enabling detailed examination of nerve size, morphology and internal fascicular structure that can integrate nerve conduction studies into clinical practice...

INTRODUCTION: In patients with potentially resectable esophageal cancer (EC), the value of endoscopic ultrasonography (EUS) after fluorine-18 labeled fluorodeoxyglucose positron emission tomography with computed tomography ((18)F-FDG-PET/CT) is questionable. Retrospectively, we assessed the impact of EUS after PET/CT on the given treatment in EC patients. METHODS: During the period 2009-2015, 318 EC patients were staged as T1-4aN0-3M0 with hybrid (18)F-FDG-PET/CT or (18)F-FDG-PET with CT and EUS if applicable in a nonspecific order...

A 9-year-old, spayed female Golden Retriever dog was referred to us for lymphocytosis and lymphadenopathy, secondary to suspected chronic lymphocytic leukemia (CLL). The dog had a clinical history of anorexia, vomiting and melena lasting two days. The popliteal lymph node contained small-to-intermediate lymphocytes, which led us to suspect low-grade lymphoma. Thickened lesions in the stomach and small intestine were detected by ultrasonography. Histopathology of the popliteal lymph node and small intestine revealed a simultaneous presence of T-zone lymphoma (TZL) and high-grade gastrointestinal (GI) cytotoxic T-cell lymphoma...
