Systemic disease conjunctivitis with

Although the compounds were isolated in quantities of only a few milligrams per kilogram of cmde plant leaves, extensive work on a variety of animal tumor systems led to eventual clinical use of these bases, first alone and later in conjunction with other materials, in the treatment of Hodgkin s disease and acute lymphoblastic leukemia. Their main effect appears to be binding tightly to tubuHn, the basic component of microtubules found in eukaryotic cells, thus interfering with its polymerization and hence the formation of microtubules required for tumor proliferation (82). 

People who should not work with organophosphate insecticides are those with organic central nervous system disease, mental disorders, epilepsy, pronounced endocrine disorders, respiratory conditions, cardiovascular diseases, circulatory disorders, gastroenteric diseases, liver or kidney disease, and chronic conjunctivitis and keratitis (Medved and Kagan 1983). 

Liver disease is often associated with edema and ascites in conjunction with elevated portal hydrostatic pressures and reduced plasma oncotic pressures. Mechanisms for retention of Na+ by the kidney in this setting include diminished renal perfusion (from systemic vascular alterations), diminished plasma volume (due to ascites formation), and diminished oncotic pressure (hypoalbuminemia). In addition, there may be primary Na+ retention due to elevated plasma aldosterone levels. 

The measurement of serum cholesterol is one of the most common tests performed in the clinical laboratory. Hypercholesterolemia (high blood cholesterol levels) can be the result of a variety of medical conditions. Among the conditions implicated are diabetes mellitus, atherosclerosis, and diseases of the endocrine system, liver, or kidney. High blood cholesterol levels do not point to a specific disease determination of cholesterol is used in conjunction with other clinical measurements mainly for confirmation of a particular diseased condition, rather than for diagnosis of a specific ailment. 

Severe infection such as gonococcal conjunctivitis requires systemic therapy, which may be used in conjunction with topical agents. Treatment of viral infections often is directed at relieving patient symptoms, because specific antiviral agents do not currently exist in most cases. Chlamydial disease requires systemic therapy frequently combined with adjunctive topical therapy. 

Lyme disease, caused by the spirochete Borrelia burgdorferi, incites a variety of ocular manifestations, the most common being a conjunctivitis that occurs in up to 10% of patients with early disease. Although the characteristics of the conjunctivitis have not been clearly defined, several reports have described fitlhcular conjunctivitis. Increased antibody titers to B. burgdorferi indicate the presence of Lyme disease. A history of tick bite or erythema chronicum migrans should alert the clinician to consider Lyme disease in the differential diagnosis in areas of the country where this disease is prevalent. Treatment of Lyme disease conjunctivitis should include topical tetracycline as an adjunct to oral doxycycline, 100 mg twice daily for 2 to 3 weeks, which is used to treat the systemic infection. 

The characteristics of MS are covered in previous chapters. In general, MS is a disease of the CNS with other systems involved when neuronal connections are disrupted. As a result, symptoms vary widely. Outcome measures and progression are reviewed in conjunction with chapter 3.1.2 on the therapeutic measures available for treatment of MS.
