    23 Jun 2014 | 5:00 pm
    Background: Mammography has established itself as the most efficient technique for the identification of the pathological breast lesions. Among the various types of lesions, microcalcifications are the most difficult to identify since they are quite small (0.1-1.0 mm) and often poorly contrasted against an images background. Within this context, the Computer Aided Detection (CAD) systems could turn out to be very useful in breast cancer control. Methods: In this paper we present a potentially powerful microcalcifications cluster enhancement method applicable to digital mammograms. The…

  • Impact of Age and Baseline NIHSS Scores on Clinical Outcomes in the Mechanical Thrombectomy Using Solitaire FR in Acute Ischemic Stroke Study [EVIDENCE-BASED MEDICINE LEVEL 2]

    Almekhlafi, M. A., Davalos, A., Bonafe, A., Chapot, R., Gralla, J., Pereira, V. M., Goyal, M., on behalf of the STAR Registry Investigators
    15 Jul 2014 | 8:01 am
    BACKGROUND AND PURPOSE: Age and stroke severity are inversely correlated with the odds of favorable outcome after ischemic stroke. A previously proposed score for Stroke Prognostication Using Age and NIHSS Stroke Scale (SPAN) indicated that SPAN-100-positive patients (ie, age + NIHSS score = 100 or more) do not benefit from IV-tPA. If this finding holds true for endovascular therapy, this score can impact patient selection for such interventions. This study investigated whether a score combining age and NIHSS score can improve patients' selection for endovascular stroke therapy. MATERIALS AND…
  • Flow Diversion versus Traditional Endovascular Coiling Therapy: Design of the Prospective LARGE Aneurysm Randomized Trial [INTERVENTIONAL]

    Turk, A. S., Martin, R. H., Fiorella, D., Mocco, J., Siddiqui, A., Bonafe, A.
    15 Jul 2014 | 8:01 am
    BACKGROUND AND PURPOSE: The goal of aneurysm treatment is occlusion of an aneurysm without morbidity or mortality. Using well-established, traditional endovascular techniques, this is generally achievable with a high level of safety and efficacy. These techniques involve either constructive treatment of the aneurysm (coils with or without an intravascular stent) or deconstruction (coil occlusion) of the aneurysm and the parent artery. While established as safe and efficacious, the constructive treatment of large and giant aneurysms with coils has typically been associated with relatively…
  • Use of Flow-Diverting Devices in Fusiform Vertebrobasilar Giant Aneurysms: A Report on Periprocedural Course and Long-Term Follow-Up [EDITOR'S CHOICE]

    Ertl, L., Holtmannspotter, M., Patzig, M., Bruckmann, H., Fesl, G.
    15 Jul 2014 | 8:01 am
    BACKGROUND AND PURPOSE: Fusiform vertebrobasilar giant aneurysms are a rare (<1% of all intracranial aneurysms) but challenging aneurysm subtype. Little data are available on the natural history of this aneurysm subtype and the impact of the use of flow-diverting stents on the long-term clinical and imaging follow-up. In this article, we present our experience with the treatment of fusiform vertebrobasilar giant aneurysms by flow diverting stents. We aim to stimulate a discussion of the best management paradigm for this challenging aneurysm subtype. MATERIALS AND METHODS: We…

    Yeom, K. W., Lober, R. M., Alexander, A., Cheshier, S. H., Edwards, M. S. B.
    15 Jul 2014 | 8:01 am
    BACKGROUND AND PURPOSE: Reduced cerebral perfusion has been observed with elevated intracranial pressure. We hypothesized that arterial spin-labeled CBF can be used as a marker for symptomatic hydrocephalus. MATERIALS AND METHODS: We compared baseline arterial spin-labeled CBF in 19 children (median age, 6.5 years; range, 1–17 years) with new posterior fossa brain tumors and clinical signs of intracranial hypertension with arterial spin-labeled CBF in 16 age-matched controls and 4 patients with posterior fossa tumors without ventriculomegaly or signs of intracranial hypertension.

  • Spontaneous migration of a portacath into the azygos vein with subsequent development of a tracheo-azygos fistula

    Matthew H Andrews, Bruce D Chisholm
    17 Jul 2014 | 2:55 am
    Summary Subcutaneous venous port or ‘portacath’ devices are widely used, especially in oncology patients. Several potential complications of portacath devices have been well documented. We report a rare case of the spontaneous migration of the tip of a portacath into the azygos vein, with subsequent development of a tracheo-azygos fistula. This resulted in the patient receiving a dose of chemotherapy agent and saline directly into his lungs, which ultimately contributed to his death a few weeks later. To our knowledge, there have been only 10 previously reported cases of inadvertent…

  • Brain region¿s relative proximity as marker for Alzheimer¿s disease based on structural MRI

    Lene Lillemark
    1 Jun 2014 | 5:00 pm
    Background: Alzheimer’s disease (AD) is a progressive, incurable neurodegenerative disease and the most common type of dementia. It cannot be prevented, cured or drastically slowed, even though AD research has increased in the past 5-10 years. Instead of focusing on the brain volume or on the single brain structures like hippocampus, this paper investigates the relationship and proximity between regions in the brain and uses this information as a novel way of classifying normal control (NC), mild cognitive impaired (MCI), and AD subjects. Methods: A longitudinal cohort of 528 subjects (170…
  • Impact of a standardized training program on midwives¿ ability to assess fetal heart anatomy by ultrasound

    Eric Hildebrand
    1 Jun 2014 | 5:00 pm
    Background: Studies of prenatal detection of congenital heart disease (CHD) in the UK, Italy, and Norway indicate that it should be possible to improve the prenatal detection rate of CHD in Sweden. These studies have shown that training programs, visualization of the outflow tracts and color-Doppler all can help to speed up and improve the detection rate and accuracy. We aimed to introduce a more accurate standardized fetal cardiac ultrasound screening protocol in Sweden. Methods: A novel pedagogical model for training midwives in standardized cardiac imaging was developed, a model using a…

  • The potential value of integrated natriuretic peptide and echo-guided heart failure management

    Maria Scali
    17 Jul 2014 | 5:00 pm
    There is increasing interest in guiding Heart Failure (HF) therapy with Brain Natriuretic Peptide (BNP) or N-terminal prohormone of Brain Natriuretic Peptide (NT-proBNP), with the goal of lowering concentrations of these markers (and maintaining their suppression) as part of the therapeutic approach in HF. However, recent European Society of Cardiology (ESC) and American Heart Association/ American College of Cardiology (AHA/ACC) guidelines did not recommend biomarker-guided therapy in the management of HF patients. This has likely to do with the conceptual, methodological, and practical…
  • Need for a standardized protocol for stress echocardiography in provoking subaortic and valvular gradient in various cardiac conditions

    Pawel Petkow Dimitrow
    13 Jul 2014 | 5:00 pm
    (Semi) supine exercise testing has an established role in the evaluation of patients with valvular heart disease and can help clinical decision making. Stress echocardiography has the advantages of its wide availability, low cost, and versatility for the assessment of disease severity. However, exercise-induced changes in valve hemodynamics, left ventricular outflow obstruction and pulmonary artery pressure depended on load variation. Changing position from supine to upright rapidly decreases load conditions for the ventricles. Therefore several cardiac centers have proposed exercise stress…
  • How I do it: Lung ultrasound

    Luna Gargani
    3 Jul 2014 | 5:00 pm
    In the last 15 years, a new imaging application of sonography has emerged in the clinical arena: lung ultrasound (LUS). From its traditional assessment of pleural effusions and masses, LUS has moved towards the revolutionary approach of imaging the pulmonary parenchyma, mainly as a point-of-care technique. Although limited by the presence of air, LUS has proved to be useful in the evaluation of many different acute and chronic conditions, from cardiogenic pulmonary edema to acute lung injury, from pneumothorax to pneumonia, from interstitial lung disease to pulmonary infarctions and…

    Abstract Both gray matter atrophy and disruption of functional networks are important predictors for physical disability and cognitive impairment in multiple sclerosis (MS), yet their relationship is poorly understood. Graph theory provides a modality invariant framework to analyze patterns of gray matter morphology and functional coactivation. We investigated, how gray matter and functional networks were affected within the same MS sample and examined their interrelationship. Magnetic resonance imaging and magnetoencephalography (MEG) were performed in 102 MS patients and 42 healthy…
  • Combined neuroimaging and gene expression analysis of the genetic basis of brain plasticity indicates across species homology

    Yonatan Dinai, Lior Wolf, Yaniv Assaf
    22 Jul 2014 | 7:23 am
    Abstract Brain plasticity and memory formation depend on the expression of a large number of genes. This relationship had been studied using several experimental approaches and researchers have identified genes regulating plasticity through a variety of mechanisms. Despite this effort, a great deal remains unknown regarding the role of different genes in brain plasticity. Previous studies usually focused on specific brain structures and many of the genes influencing plasticity have yet to be identified. In this work, we integrate results of in vivo neuroimaging studies of plasticity with…
  • Combining diffusion tensor imaging and magnetic resonance spectroscopy to study reduced frontal white matter integrity in youths with family histories of substance use disorders

    Ashley Acheson, S. Andrea Wijtenburg, Laura M. Rowland, Bethany C. Bray, Frank Gaston, Charles W. Mathias, Peter T. Fox, William R. Lovallo, Susan N. Wright, L. Elliot Hong, Stephen McGuire, Peter Kochunov, Donald M. Dougherty
    20 Jul 2014 | 9:55 pm
    Abstract Individuals with a family history of substance use disorder (FH+) show impaired frontal white matter as indicated by diffusion tensor imaging (DTI). This impairment may be due to impaired or delayed development of myelin in frontal regions, potentially contributing to this population's increased risk for developing substance use disorders. In this study, we examined high angular resolution DTI and proton magnetic resonance spectroscopy data from the anterior corona radiata were collected in 80 FH+ and 34 FH− youths (12.9 ± 1.0 years old). White matter integrity indices…

    18 Jul 2014 | 3:25 am
    ABSTRACT Arteriovenous malformations (AVM) of the uterus can cause life-threatening hemorrhage. Unexplained, heavy vaginal bleeding in a reproductive age woman should raise suspicion for an AVM. Here a 37-year-old woman had increasingly severe vaginal bleeding for 15 days. Serum β-hCG was elevated. Two-dimensional transvaginal ultrasound suggested retained products of conception. Before dilation and curettage (D&C), color Doppler and three-dimensional (3D) power Doppler demonstrated findings indicative of uterine AVM. A bilateral uterine artery embolization was performed without…

    Akiko Yamashita, Nobuhiro Hidaka, Ryo Yamamoto, Soichiro Nakayama, Jun Sasahara, Keisuke Ishii, Nobuaki Mitsuda
    15 Jul 2014 | 3:35 am
    ABSTRACT Fetal congenital cystic adenomatoid malformation (CCAM) can progress to nonimmune hydrops, and the mortality rate of CCAM with hydrops is reported to be nearly 100%. We describe three microcystic CCAM cases in which the fetal condition improved after maternal betamethasone therapy. The median gestational age at steroid administration was 23 5/7 weeks' gestation. The CCAM decreased in size in all cases. Our series showed a 100% hydrops resolution rate (2/2) and a 100% survival rate (3/3). Our experience suggests the efficacy of betamethasone treatment on fetuses with microcystic CCAM…

  • Ototoxicity evaluation in medulloblastoma patients treated with involved field boost using intensity-modulated radiation therapy (IMRT): a retrospective review

    Wilson Vieira
    20 Jul 2014 | 5:00 pm
    Background: Ototoxicity is a known side effect of combined radiation therapy and cisplatin chemotherapy for the treatment of medulloblastoma. The delivery of an involved field boost by intensity modulated radiation therapy (IMRT) may reduce the dose to the inner ear when compared with conventional radiotherapy. The dose of cisplatin may also affect the risk of ototoxicity. A retrospective study was performed to evaluate the impact of involved field boost using IMRT and cisplatin dose on the rate of ototoxicity. Methods: Data from 41 medulloblastoma patients treated with IMRT were collected.

    Researchers from University College London in the UK are developing a simple blood test to help predict the likelihood of a woman developing breast cancer. They publish their research in the open access journal Genome Medicine The University College London (UCL) team first identified an epigenetic signature that can be detected in the blood of women who have an inherited genetic mutation that predisposes them to breast cancer. The mutation occurs in the BRCA1 gene and is believed to cause at least 10% of breast cancers. The causes behind the other 90% of cancers are unknown, however.

  • Lung Cancer Screening Gets Another Leg Up

    Diagnostic Imaging Centers, P.A.
    25 Jun 2014 | 1:20 pm
    The votes in support of low-dose screening CT chest for high risk smokers are growing. Recently the American Medical Association – the largest association of doctors from all specialties in the US – added their support to guidelines recommending this potentially life-saving exam.   Lung cancer is a killer. In the US, lung cancer causes more deaths than breast + prostate + colon cancer – more deaths than all of those cancers combined! Studies on low-dose CT screening (the National Lung Screening Trial) showed early detection saves lives! There was a 20% reduction in…

    My new neuro/seizure meds have been brilliant in making me not only feel better but in stopping leg locking and leg spasms. The pain meds I started on Monday haven’t been so good. I have had tremendous pain yesterday and today, my limbs swelled and muscles are burning. I phoned my pain clinic specialtist but she wasn’t in so was referred back to my doctors to help. My Dr was really quick in getting back to me and has highered the meds to four times a day instead of two. I am really hoping this will help, the pain hasn’t faded so far and by past experience I know will linger…

    This morning the nurse told us that the plan for today was to place a NJ tube into Mackenzie.  The NG tube would be taken out.  The NJ tube goes down past your stomach into your intestines and delivers nutrition through there.  The hope was that while they are inserting it that it would be able to be pushed past the blockage and then stay there while she gets nutrition the right way…and then she would theoretically gain fat and weight and the issue would resolve itself.  The nurse said that the procedure would be at 2pm. One of my questions was that if this does fix itself, would it…
  • Annie and the scary floor

    Annie enjoying the sun A few months ago Annie developed a strange phobia about an area of the kitchen.  One day she was fine, galumping around all over the place and the next she had pinned her ears to her head, tucked her tail and flatly refused to come to either one of us if we stood anywhere near the dishwasher. Human logic being what it is (flawed) we initially thought the dishwasher had made a noise and scared her. With reports of sink holes opening up around the country I have to confess to a mild does of paranoia which had me checking the exterior walls for any signs of subsidence…

    There are times when I meet people who speak and only speak. I am sure we have actually gotten phone calls from people who speak and speak and somehow whatever you say hits the wall. There are times when you know this person is not going to get the point you are trying to make just because he didn't learn the art of listening in school. Hearing out the other person out is a skill and making mental notes of the conversation helps a lot especially when you are discussing something important. Try this voluntarily if this is not a skill with you. Most people over-rate speaking and keep speaking…

Are you one of those who believe in first creating your Taj Mahal and then selling it? Is this what your school teacher taught you? I simply don't agree. Idea of success in life, business and exams is knowing right time to act and make quick decisions. I know of people who wait till they achieve perfection to actually launch the product to market and realize that the idea doesn't sell. Taj Mahal is good to see , people will…
