The work generalized the results of examination of 418 patients with primary varicosity (V) complicated by trophic ulcers. On the basis of the study conducted by the authors, a conception of pathogenesis is suggested, the main links of which are microcirculatory disorders in the system of perforating veins of a closed structure, and deficient resolution of fibrin due to diminished local fibrinolytic activity of the plasma. Insufficient fibrin splitting leads to the formation of paravasal collagen cuffs preventing normal exchange between the capillaries and tissues. Impaired nutrition facilitates spasm of arteries and arterioles, whose genesis magnesium deficit contributes to. Activation of collagenolytic peptidases-cathepsins, D, A, B occurs in the ischemic tissues, which leads to destruction of the skin and the formation of ulcers. The disease is attended by disorders of immunity (secondary immunodeficiency), which reduces the reparative processes and thus promotes the development of a chronic process. A complex approach to the treatment of V in the presence of trophic ulcers is suggested.

Bartonella, genus Proteus, can cause immunodepressive disease. The organisms, in parasitized red blood cells, may invade the brain and every other system and space in the human body. Bartonella henselae is proposed to have a role in the pathogenesis of acquired immunodeficiency syndrome (AIDS) encephalopathy. Bartonella bacilliformis produces two known toxins that can induce spasm and angiomatosis, respectively, and manifest as diseases associated with symptomatic AIDS. The skin lesions of bartonellosis may be mistaken clinically and histologically for Kaposi's sarcoma. Bacteria of the genus Proteus produce L-forms: their elementary bodies may be mistaken for what are called the 'human immunodeficiency viruses' (HIV). Antibiotics, especially penicillin, induce bacteria to produce L-forms. Air pollution and high sugar, salt and fat diets are factors that may increase the lipid content of microbes that produce toxins and L-forms that may persist or revert to bacterial form.

Uveitis is the inflammation of any or all parts of the vascular tunic of the eye; the vascular tunic includes the iris, the ciliary body, and choroid. A good knowledge base, up-to-date reference materials, and good instruments will improve the diagnosis of uveitis. Feline uveitis can be caused by numerous infectious agents in addition to neoplasia and less likely trauma. The infectious causes most commonly associated with feline uveitis include feline leukemia virus, feline immunodeficiency virus, feline infectious peritonitis, systemic fungal infections, toxoplasmosis, and bartonellosis. Neoplastic causes of uveitis can be primary or secondary. Iris melanoma is the most common primary uveal neoplasia and trauma-associated sarcoma is the second most common primary uveal neoplasia. Treatment for the clinical signs of anterior uveitis include topical steroidal or non-steroidal anti-inflammatory agents, parasympatholytic agents for ciliary spasm, to keep the pupil dilated, and to prevent posterior synechia. Posterior uveitis should be treated with systemic medications that will address the underlying cause. Enucleation of blind, painful eyes not responsive to medications is a means to alleviate the animal's discomfort and to further diagnose the underlying cause.

Ergotism is a complication of the acute intoxication or chronic abuse of ergot derivatives. It may be manifested by a vasomotor syndrome with peripheral vascular disease frequently involving extremities. We report three patients infected with human immunodeficiency virus (HIV), in antiretroviral treatment (ART) that included a protease inhibitor as ritonavir, and had received self-medicated ergotamine. They developed symptoms of peripheral vascular disease and the physical examination showed no arterial pulses in the affected vessels. Arterial Doppler confirmed signs of diffuse arterial spasm in all of them. An arteriography was performed to the second patient and it showed obliteration of the distal sector of the ulnar and radial arteries. Ergotism secondary to ergotamine-ritonavir association was diagnosed. Patients were treated discontinuing the administration of involved drugs, arterial vasodilators and prophylactic anticoagulation, with marked improvement of symptoms.
