The German Dermatological Society indicated that Diosmin may be used with other treatments for symptoms of chronic venous diseases.The American Society of Colon and Rectal Surgeons mentions phlebotonics as a possible treatment for symptoms of hemorrhoid grades I to II, as there is only moderate-quality evidence of effectiveness with "expectations of minimal harm", while having no evidence of long-term benefit. French, Indian, Portuguese, and Italian professional societies of coloproctology issued similar recommendations regarding phlebotonics for hemorrhoids. Adverse effects
In some 10% of users, diosmin causes mild gastrointestinal disorders or skin irritations (hives, itching), stomach pain, nausea, heart arrhythmias, or anemia. Preliminary research indicates no evidence of toxicity. The US Food and Drug Administration (FDA) concluded in 2001 that there was inadequate evidence on which to base an expectation of safety. As of 2013, the FDA did not revise this position. Regulatory status
Diosmin is distributed in the U.S. as a dietary supplement called Daflon. Diosmin is not approved as a prescription drug in the United States or Europe. Phlebotonics are not approved in Germany, and are restricted in Spain only for the treatment of chronic venous diseases. See also

Bronchoalveolar Lavage (BAL) findings coinciding with pneumonitis typically include a lymphocytosis with a low CD4:CD8 ratio.Reticular or linear patterns may be observed in diagnostic imaging. Pneumonitis may cause subpleural honeycombing, changing the shape of the air spaces in an image, which may be used to identify the respiratory diseas.e The interlobular septa may also thicken and indicate pneumonitis when viewed on a scan.Histological samples of lung tissue with pneumonitis include the presence of poorly formed granulomas or mononuclear cell infiltrates. The presence of bronchocentric lymphohistiocytic interstitial pneumonia with chronic bronchiolitis and non-necrotising granulomas coincides with pneumonitis.Since pneumonitis manifests in all areas of the lungs, imaging such as chest x-rays and Computerized tomography (CT) scans are useful diagnostic tools. While pneumonia is a localized infection, pneumonitis is widespread. A spirometer may also be used to measure pulmonary function. During external examination, clubbing (swelling of fingertip tissue and increase in angle at the nail bed), and basal crackles may be observed. For hypersensitivity pneumonitis many diagnoses take place through the focus of blood test, chest x-rays, and depending on severity of infection doctors may recommend a bronchoscopy. Blood test are important to early detect for other causative substances that could eliminate possible causes of the hypersensitivity pneumonitis. Classification
Pneumonitis can be separated into several distinct categories based upon causative agent. Hypersensitivity Pneumonitis (Extrinsic Allergenic Alveolitis) describes the inflammation of alveoli which occurs after inhalation of organic dusts (oxford). These particles can be proteins, bacteria, or mold spores and are usually specific to an occupation.
