Realtime elastosonography of the penis in patients with Peyronie's disease

Objective: To evaluate the performance of real time elastosonography (RTE) in the iden- tification of different types of penile lesions in patients with Peyronie’s disease. Materials and methods: Seventy four consecutive patients with complaints of Peyronie’s disease underwent B-Mode ultrasonography (US) and RTE of the penis in the same sit- ting. In each patient all sequences of elastosonography and B-Mode US were recorded and compared to evaluate the diagnostic performance of the new imaging technique. Results: B-Mode US detected penile plaques in 64 patients (86.41%) and elastosonography con- firmed these data. In the remaining 10 patients elastosonography documented, in five of them, areas of reducing elasticity suggesting the presence of initial fibrosis. Cohen’s K was used to eval- uate the discordances between B-Mode US and Elastosonography scan. A p value 30°, and the penile plaque evalua- tions were completely concordant. Conclusions: RTE is a simple, non invasive, rapid complementary imaging technique that may improve the accuracy of B-Mode US in detecting penile lesions in patients with Peyronie’s disease

Incidental extravascular findings in computed tomographic angiography for planning or monitoring endovascular aortic aneurysm repair: Smoker patients, increased lung cancer prevalence?

AIMTo validate the feasibility of high resolution computed tomography (HRCT) of the lung prior to computed tomography angiography (CTA) in assessing incidental thoracic findings during endovascular aortic aneurysm repair (EVAR) planning or follow-up.METHODSWe conducted a retrospective study among 181 patients (143 men, mean age 71 years, range 50-94) referred to our centre for CTA EVAR planning or follow-up. HRCT and CTA were performed before or after 1 or 12 mo respectively to EVAR in all patients. All HRCT examinations were reviewed by two radiologists with 15 and 8 years' experience in thoracic imaging. The results were compared with histology, bronchoscopy or follow-up HRCT in 12, 8 and 82 nodules respectively.RESULTSThere were a total of 102 suspected nodules in 92 HRCT examinations, with a mean of 1.79 nodules per patient and an average diameter of 9.2 mm (range 4-56 mm). Eighty-nine out of 181 HRCTs resulted negative for the presence of suspected nodules with a mean smoking history of 10 pack-years (p-y, range 5-18 p-y). Eighty-two out of 102 (76.4%) of the nodules met criteria for computed tomography follow-up, to exclude the malignant evolution. Of the remaining 20 nodules, 10 out of 20 (50%) nodules, suspected for malignancy, underwent biopsy and then surgical intervention that confirmed the neoplastic nature: 4 (20%) adenocarcinomas, 4 (20%) squamous cell carcinomas, 1 (5%) small cell lung cancer and 1 (5%) breast cancer metastasis); 8 out of 20 (40%) underwent bronchoscopy (8 pneumonia) and 2 out of 20 (10%) underwent biopsy with the diagnosis of sarcoidosis.CONCLUSIONHRCT in EVAR planning and follow-up allows to correctly identify patients requiring additional treatments, especially in case of lung cancer

Acute exacerbation of idiopathic pulmonary fibrosis after inhalation of a water repellent

The natural course of idiopathic pulmonary fibrosis (IPF) is unpredictable at the time of diagnosis. Some patients may experience episodes of acute respiratory worsening that have been termed acute exacerbations. A 58-year-old male was admitted to our Emergency Department due to progressive and intense dyspnea and dry cough after accidental inhalation of waterproof's vapor containing siloxanes. Chest high resolution computed tomography (HRCT) scan showed diffuse and bilateral ground glass attenuation, basal predominant reticular abnormalities and subpleural honeycombing. The patient didn't know that he suffered from IPF and siloxanes' inhalation triggered an acute exacerbation of his disease. Clinical course after the inhalation was aggressive and, despite steroids and cyclophosphamide therapy, the patient died 3 months after due to a respiratory failure. Inhalation of water repellents has been associated with an acute onset of respiratory symptoms and acute lung injury; usually, however, the prognosis is commonly good with a complete recovery. Our case is an example of an extremely negative reaction probably because of pre-existing and misdiagnosed IPF. Currently, no literature concerning water repellent inhalation as a trigger of acute exacerbation of IPF is available

Magnetic resonance lymphangiography: with or without contrast?

Lymphedema is an important medical issue around the world, caused by an anomalous collection of fluid in soft tissue due to congenital malformations or stenosis or obstruction of lymphatic vessels. Magnetic resonance lymphangiography (MRL) is an emerging technique focused on noninvasive or minimally invasive imaging of lymphatics with the goal to diagnose and treat lymphedema. This review will briefly discuss lymphatic imaging starting with lymphography and radionuclide lymphoscintigraphy up to the newest methods, focusing on MRL, a rising technique, and highlighting the technical aspects fundamental for achieving high-resolution MRL

Magnetic resonance imaging: Is there a role in clinical management for acute ischemic colitis?

AIM: To validate the utility of magnetic resonance imaging (MRI) for the clinical management of acute ischemic colitis (IC). METHODS: This is a magnetic resonance (MR) prospective evaluation of 7 patients who were proved to have acute IC on the basis of clinical, endoscopic and computed tomography (CT) findings and who were imaged in our institution between February 2011 and July 2012. The mean age of the patients was 72.28 years. Abdominal CTs were obtained using a 64-detector row configuration for all patients with un-enhanced and contrast-enhanced scans, in the late arterial phase (start delay 45-50 s) and in the portal venous phase (start delay 70-80 s). The MR examinations were performed using a 1.5T superconducting magnet, using Fast Imaging Employing Steady State Acquisition and T2-weighted fast-recovery fast-spin echo sequences in axial and coronal plane. CT and MRI examinations were analysed for the presence of colonic abnormalities and associated findings. RESULTS: Segmental involvement was seen in 6 patients (85.71%), with a mean length of involvement of 412 mm (range 145.5-1000 mm). Wall thickness varied between 6 mm and 17.5 mm (mean 10.52 mm) upon CT examinations and from 5 to 15 mm (mean 8.8 mm) upon MR examinations. The MRI appearance of the colonic wall varied over the time: Type I appearance with a 3 layer sandwich sign was seen in 5 out of 12 examinations (41.66%), patients underwent MR within a mean of 36 h (ranging from 1 to 54 h) after the CT examination. Type II and III appearance with a 2 layer sign, was seen in 4 examinations (33.33%), patients underwent MR within a mean of 420.5 h (ranging from 121 to 720 h) after the CT examination. In the remaining three MRI examinations, performed within a mean of 410 h (ranging from 99.5 to 720 h) the colonic wall appeared normal. CONCLUSION: MRI, only using precontrast images, may be used as a substitute for invasive procedures in diagnosis and follow-up of acute IC

Dose/dense metronomic chemotherapy with fractioned cisplatin and oral daily etoposide enhances the anti-angiogenic effects of bevacizumab and has strong antitumor activity in advanced non-small-cell-lung cancer patients.

Background: We designed a translational clinical trial to investigate whether a dose/dense chemotherapy regimen is able to enhance in patients with non-small-cell-lung-cancer, the anti-angiogenic, and anti-tumor activity of bevacizumab, a murine/human monoclonal antibody to the vasculo-endothelial-growth-factor (VEGF) Patients and Methods: Forty-eight patients (42 males and 6 females) with stage IIIB/IV non-small-cell-lung-cancer, a mean age of 68 years, and ECOG ≤ 2 were enrolled in the study. They received every three weeks fractioned cisplatinum (30 mg/sqm, days 1-3) and oral etoposide (50 mg, days 1-15) and were divided in 5 cohorts receiving different bevacizumab dosages [0; 2.5; 5; 7.5; and 10 mg/kg] on the day 3. Results: The combined treatment was able of inducing a significant decline in the blood-perfusion of primary tumor (NMR-study); in serum levels of VEGF, angiopoietin-1, thrombospondin-1; and in the number of VEGF-transporting cells. In the group of 40 patients who received bevacizumab ther..

Structured and shared CT radiological report of gastric cancer: a consensus proposal by the Italian Research Group for Gastric Cancer (GIRCG) and the Italian Society of Medical and Interventional Radiology (SIRM)

Objectives Written radiological report remains the most important means of communication between radiologist and referring medical/surgical doctor, even though CT reports are frequently just descriptive, unclear, and unstructured. The Italian Society of Medical and Interventional Radiology (SIRM) and the Italian Research Group for Gastric Cancer (GIRCG) promoted a critical shared discussion between 10 skilled radiologists and 10 surgical oncologists, by means of multi-round consensus-building Delphi survey, to develop a structured reporting template for CT of GC patients. Methods Twenty-four items were organized according to the broad categories of a structured report as suggested by the European Society of Radiology (clinical referral, technique, findings, conclusion, and advice) and grouped into three "CT report sections" depending on the diagnostic phase of the radiological assessment for the oncologic patient (staging, restaging, and follow-up). Results In the final round, 23 out of 24 items obtained agreement ( >= 8) and consensus ( 0.05). Conclusions The structured report obtained, shared by surgical and medical oncologists and radiologists, allows an appropriate, clearer, and focused CT report essential to high-quality patient care in GC, avoiding the exclusion of key radiological information useful for multidisciplinary decision-making

Incidental and Underreported Pleural Plaques at Chest CT: Do Not Miss Them - Asbestos Exposure Still Exists

Pleural plaques (PPs) may be a risk factor for mortality from lung cancer in asbestos-exposed workers and are considered to be a marker of exposure. Diagnosing PPs is also important because asbestos-exposed patients should be offered a health surveillance that is mandatory in many countries. On the other hand PPs are useful for compensation purposes. In this study we aimed to evaluate the prevalence, as incidental findings, and the underreporting rate of PPs in chest CT scans (CTs) performed in a cohort of patients (1512) who underwent chest CT with a slice thickness no more than 1.25 mm. PPs were found in 76 out of 1482 patients (5.1%); in 13 out of 76 (17,1%) CTs were performed because of clinical suspicion of asbestos exposure and 5 of them (38%) were underreported by radiologist. In the remaining 63 cases (82.9%) there was no clinical suspicion of asbestos exposure at the time of CTs (incidental findings) and in 38 of these 63 patients (60.3%) PPs were underreported. Reaching a correct diagnosis of PPs requires a good knowledge of normal locoregional anatomy and rigorous technical approach in chest CT execution. However the job history of the patient should always be kept in mind
