SYMPTOMATIC COLITIS AS THE INITIAL PRESENTATION OF WEGENER'S GRANULOMATOSIS

SUMMARY Wegener's granulomatosis is a multisystem disorder which rarely presents with gastrointestinal involvement. We report a case in which colitis was the reason for hospital admission. Diagnosis may be difficult unless clinical, serological and histopathological features are all considered.     

A neural link to explain the "muscle hypothesis" of exercise intolerance in chronic heart failure.

BACKGROUND: In chronic heart failure the cause of exercise limitation is still unclear: ergoreceptors, muscle afferents sensitive to exercise metabolites, are proposed as a neural link between muscular abnormalities and the limited exercise responses in this syndrome. METHODS: In 92 stable patients with heart failure (34 in New York Heart Association class I, 27 in class II, and 31 in class III) and 28 age-matched normal controls, we assessed exercise tolerance (maximal upright bicycle) and ergoreflex activity (2 dynamic hand grips: one control and one followed by 3 minutes of local circulatory occlusion to isolate the ergoreflex component by metabolite trapping). RESULTS: Patients, with respect to the controls, showed reduced exercise tolerance (peak VO2: 20 vs 33 mL/kg/min), increased ergoreflex effects on ventilation (9 vs 4 L/min), systolic pressure (37 vs 13 mm Hg), and leg vascular resistance (45 vs 22 units) (all P <.005); with the progression of the symptoms, a progressive increase in ergoreflex contribution to the ventilatory response to exercise was observed. The indexes of exercise limitation during arm and leg exercise (ie, peak VO 2, V/VCO2 slope) correlated highly with the ergoreflex contribution to ventilatory response during handgrip test ( r 相似文献   

Assessing and grading congestion in acute heart failure: a scientific statement from the Acute Heart Failure Committee of the Heart Failure Association of the European Society of Cardiology and endorsed by the European Society of Intensive Care Medicine

Patients with acute heart failure (AHF) require urgent in‐hospital treatment for relief of symptoms. The main reason for hospitalization is congestion, rather than low cardiac output. Although congestion is associated with a poor prognosis, many patients are discharged with persistent signs and symptoms of congestion and/or a high left ventricular filling pressure. Available data suggest that a pre‐discharge clinical assessment of congestion is often not performed, and even when it is performed, it is not done systematically because no method to assess congestion prior to discharge has been validated. Grading congestion would be helpful for initiating and following response to therapy. We have reviewed a variety of strategies to assess congestion which should be considered in the care of patients admitted with HF. We propose a combination of available measurements of congestion. Key elements in the measurement of congestion include bedside assessment, laboratory analysis, and dynamic manoeuvres. These strategies expand by suggesting a routine assessment of congestion and a pre‐discharge scoring system. A point system is used to quantify the degree of congestion. This score offers a new instrument to direct both current and investigational therapies designed to optimize volume status during and after hospitalization. In conclusion, this document reviews the available methods of evaluating congestion, provides suggestions on how to properly perform these measurements, and proposes a method to quantify the amount of congestion present.     

Dental Expression and Role in Palliative Treatment

World Health Organization defines palliative care as the active total care of patients whose disease is not responding to curative treatment. Palliative care for the terminally ill is based on a multidimensional approach to provide whole-person comfort care while maintaining optimal function; dental care plays an important role in this multidisciplinary approach. The aim of the present study is to review significance of dentist''s role to determine whether mouth care was effectively assessed and implemented in the palliative care setting. The oral problems experienced by the hospice head and neck patient clearly affect the quality of his or her remaining life. Dentist plays an essential role in palliative care by the maintenance of oral hygiene; dental examination may identify and cure opportunistic infections and dental disease like caries, periodontal disease, oral mucosal problems or prosthetic requirement. Oral care may reduce not only the microbial load of the mouth but the risk for pain and oral infection as well. This multidisciplinary approach to palliative care, including a dentist, may reduce the oral debilities that influence the patient''s ability to speak, eat or swallow. This review highlighted that without effective assessment of the mouth, the appropriate implementation of care will not be delivered. Palliative dental care has been fundamental in management of patients with active, progressive, far-advanced disease in which the oral cavity has been compromised either by the disease directly or by its treatment; the focus of care is quality of life.
