Airway obstruction in relation to symptoms in chronic respiratory disease—a nationally representative population study

2000

Abstract We examined the severity of airway obstruction and the occurrence of respiratory symptoms in a large, nationally representative population sample and in a subgroup of subjects with chronic bronchitis and/or emphysema to obtain information for developing national prevention and treatment strategies for these diseases. The study population comprised of 7217 randomly selected subjects (aged 30 years and older) who participated in a comprehensive health examination survey. The ‘cases' were subjects diagnosed as having chronic bronchitis and/or emphysema. The survey methods comprised of questionnaires, interviews, physical measurements, including spirometry, and clinical examinations. I…

Modified Devine Exclusion for Unresectable Distal Gastric Cancer in Symptomatic Patients

2017

<b><i>Background:</i></b> In patients with outlet obstruction syndrome and/or severe anemia secondary to unresectable gastric cancer (GC), partial stomach-partitioning gastrojejunostomy, or modified Devine exclusion, is a surgical alternative. <b><i>Methods:</i></b> A retrospective study was conducted on patients with unresectable distal GC treated with modified Devine exclusion as palliative surgery between February 2005 and December 2015. It consisted of a series of 10 patients with outlet obstruction syndrome and/or severe anemia. The outcomes of this technique were based on oral tolerance, blood transfusions, postoperative complications, a…

The role of MR imaging in the assessment of renal allograft vasculature.

2018

Renal allograft dysfunction after transplantation is a relatively common occurrence with various potential etiologies. Vascular etiologies are of particular importance as early surgical or minimally invasive intervention can, in some cases, salvage the graft. Diagnosis of vascular pathology resulting in allograft dysfunction requires a thorough workup, of which imaging is a key component. Generally, ultrasound is the first-line imaging modality. More recently, MRI has been shown to be an effective and safe modality for diagnosis of vascular pathology after renal transplantation, particularly for diagnosis of transplant renal artery stenosis. This review will summarize imaging modalities tha…

Extreme ameloblastoma of the mandible with hypoproteinemia. A case report and review of clinicopathological features

2011

Ameloblastoma is a tumor of odontogenic epithelium. It has an intermediate malignant potential, thus positioning it in a gray zone between benign and malignant neoplasms. Invasive ameloblastomas of excessive size are rarely confronted. Although these ameloblastomas are benign, they are life threatening. Many have eventuated in death due to airway obstruction, starvation from restriction of feeding, and complications of hypoproteinemia. These tumors cause significant expansion of skin and lips [tissue expanders]. Due to its metabolic demands, a tumor of enormous size will have numerous feeding vessels. Patients with extreme ameloblastomas are usually from rural areas of developing countries …

Extension theory and the calculus of butterflies

2016

Abstract This paper provides a unified treatment of two distinct viewpoints concerning the classification of group extensions: the first uses weak monoidal functors, the second classifies extensions by means of suitable H 2 -actions. We develop our theory formally, by making explicit a connection between (non-abelian) G-torsors and fibrations. Then we apply our general framework to the classification of extensions in a semi-abelian context, by means of butterflies [1] between internal crossed modules. As a main result, we get an internal version of Dedecker's theorem on the classification of extensions of a group by a crossed module. In the semi-abelian context, Bourn's intrinsic Schreier–M…

Tailored treatments in internal rectal prolapse

2020

Background: Internal rectal prolapse is commonly reported in patients suffering pelvic floor disorders, such as obstructive defecation and incontince. Unfortunately, its treatment not always offers a symptoms resolution. Material and methods: To investigate the correct management and its influence in symptoms resolution, we investigated patients submitted to hierarchic therapeutic options from conservative to surgical treatments. An evaluation of the appropriate treatment tailored on the entity of the prolapse was proposed. Results: We investigated 84 patients [64 F, 20 M (median age 52)]. In 44 a symptoms resolution was obtained with medical therapy. To 40 patients biofeedback rehabilitati…
