Chronic processes

O Osteomyelitis, an infection of the bone, can be an acute or chronic process. 

In the case of chronic processes, the patient can, at any time, take the decision to stop the treatment, as a reaction to changes in price or other variables. Whereas the econometric technique for analysing the demand for pharmaceuticals for acute processes is that of discrete choice models, here we will apply duration or survival models. In addition, the technology of drags for chronic diseases can have non-constant returns to scale. For example, the consumption of anxiolytics raises the tolerance and reduces the effect, resulting in an increase in the necessary dose. 

If the body s resistance is not strong, the Qi and blood are too weak to push out the toxin. Pus forms but the boil or carbuncle does not perforate and discharge pus. The disorder then leads to a chronic process. 

This formula can push toxin outward and discharge pus. It is used for treating an abscess that leads to a chronic process. The abscess is accompanied by localized pain, swelling, heat and production of pus but without signs of perforation. This is because the Qi is deficient and it is unable to push the toxin outward and discharge the pus. Instead, an abscess is formed under the skin. The accumulated toxin creates pain, swelling and heat. 

Band-shaped keratopathy is caused by the deposition of calcium salts in the basement membrane of the corneal epithelium and superficial stroma. It is typically a chronic process that develops over a period of months and years, and is associated with chronic corneal or intraocular inflammation. 

The atherosclerotic lesions develop in a complex, chronic process. The first detectable lesion is the so-called fatty streak, an aggregation of lipid-laden macrophage foam cells. The next stage of development is the formation of plaques consisting of a core of lipid and necrotic cell debris covered by a layer of connective tissue and smooth muscle cells. These plaques hinder arterial blood flow and may precipitate clinical events by plaque rupture and thrombus formation. Platelets from the thrombi, activated macrophages, and smooth muscle cells release growth factors and cytokines resulting in an inflammatory-fibroproliferative response that leads to the advanced lesions of atherosclerosis. 

Chronic liver diseases are generally associated with an increase in y-globulins, which is indicative of the effects of the chronic process on the liver mesenchyma. (lOO) Gamma globulins invariably possess features of antibodies and are therefore termed immunoglobulins. 

Since the use of tobacco is a chronic process, the effects of an aqueous extract of STE in rats following low-dose exposure were examined. Female Sprague-Dawley rats were treated orally with 25mg STE/kg every other day for 105 days. The effects of subchronic treatment of STE on hepatic microsomal and mitochondrial lipid peroxidation were assessed. Urinary excretion of the four lipid metabolites malondialdehyde, formaldehyde, acetaldehyde, and acetone was monitored by HPLC, with maximum increases being observed between 60 and 75 days of treatment. The assessment of lipid peroxidation was based on the formation of thiobarbituric acid-reactive substances (TEARS) over the 105 days of the study. 

In conclusion it may be stated that cathepsin is an earlier observable, longer persisting, and more universal indicator of hepatic lesions than the transaminases, since when increased it indicates not only both acute and chronic processes, but also cases of mechanical icterus. The differential diagnosis should be supported by additional tests. 

In most health care organizations, people have learned to work aroimd im-necessary complexity, process failures, and other system issues. When people adapt their practices to faulty systems, waste is usually produced. Waste in processes adds additional cost burdens and frustration to the work of patient care. Chronic process failure becomes normalized deviance that is not only costly it also adds risk of accidents in the care system.

Neuromuscular changes were described in detail by Toussaint et al. (1959). Degeneration of the neural elements occurs rarely and is suggestive of a chronic process. The sum of pathologic changes in muscle corresponds to the clinical finding of neurogenic muscular atrophy.
