Heel pain is most commonly the result of mechanical abnormality in foot structure or function. Systemic disease, however, may also affect the heel, resulting in pain, deformity, or both of the rearfoot. This article discusses and reviews notable systemic conditions, exclusive of the seronegative spondyloarthropathies, which may produce subjective or objective heel findings. Specific conditions discussed are rheumatoid arthritis, crystal deposition arthropathies, osteoporosis, diffuse idiopathic skeletal hyperostosis, diabetes mellitus, hypertrophic osteoarthropathy, Paget's disease, hyperlipidemia, sarcoidosis, sickle cell anemia, and acromegaly and their effects on the heel.

Sixty-eight foreign-born Hispanic patients with angiography-proven retinal-vein occlusion (RVO) and 50 age-, sex-, and race-matched controls were evaluated for systemic disease. Thirty of the RVO patients had central retinal-vein occlusion, and 38 had branch retinal-vein occlusion. Hypertension, the most commonly associated factor, was present in 66.2% of the RVO patients in contrast to 18% of the controls (P less than .001). Other factors which were more common in the RVO population included open-angle glaucoma (19.1% vs 8%), diabetes mellitus (16.2% vs 12%), and atherosclerotic heart disease (14.7% vs 10%); these, however, were not statistically significant (P greater than .05). Hyperlipidemia was present in 12% of the controls and 10.3% of the RVO group (P greater than .50). This is in direct contrast to reports of nonHispanic populations where hyperlipidemia has been reported to be present in up to 60% of RVO patients.

14 cases of posterior ischemic optic neuropathy (PION) were clinically analyzed, in whom we excluded known etiologies of optic nerve disturbances and confirmed the decreased blood supply to the posterior portion of the optic nerve. On the basis of our clinical findings, we have proposed the following criteria for the diagnosis of idiopathic PION: (1) sudden onset of unilateral visual disturbance in older patients; (2) normal optic disc, subsequently developing simple optic atrophy; (3) hypertensive and arteriosclerotic changes in the retinal vessels; (4) varying degrees of impaired vision, variable visual field defects; (5) associated systemic disease such as hypertension, diabetes mellitus, hyperlipemia, hypotension, etc.; (6) exclusion of other demonstrable causes of optic nerve disturbances, and (7) confirmation of abnormal hemodynamics in the posterior portion of the optic nerve by carotid angiography, ophthalmodynamography, ophthalmodynamometry and fluorescein fundus angiography.

Preeclampsia is a systemic disease characterized by diffuse endothelial dysfunction, increased peripheral vascular resistance, coagulation abnormalities, antioxidant deficiency, persistent elevations of maternal leukocyte-derived cytokines, and hyperlipidemia. Fish oil, rich in omega-3 polyunsaturated fatty acids, is known to reduce fasting and postprandial triglycerides and to decrease platelet and leukocyte reactivity; it may also decrease blood pressure. Additionally, omega-3 fatty acids may beneficially influence vessel wall characteristics and blood rheology. In light of the potential beneficial effects of dietary omega-3 fatty acids, we conducted a cross-sectional case-control study to examine the hypothesized exposure-effect relation between maternal dietary intake of marine omega-3 fatty acids and risk of preeclampsia. We measured polyunsaturated fatty acids in erythrocytes obtained from 22 preeclamptic women and 40 normotensive women; we measured polyunsaturated fatty acids as the percentage of total fatty acids from gas chromatography. We employed logistic regression procedures to estimate odds ratios (ORs) and 95% confidence intervals (CIs). After adjusting for confounders, women with the lowest levels of omega-3 fatty acids were 7.6 times more likely to have had their pregnancies complicated by preeclampsia as compared with those women with the highest levels of omega-3 fatty acids (95% CI = 1.4-40.6). A 15% increase in the ratio of omega-3 to omega-6 fatty acids was associated with a 46% reduction in risk of preeclampsia (OR = 0.54; 95% CI = 0.41-0.72). Low erythrocyte levels of omega-3 fatty acids and high levels of some omega-6 fatty acids, particularly arachidonic acid, appear to be associated with an increased risk of preeclampsia.

The medical records from 9 consecutive miniature horses (n = 5) and miniature donkeys (n = 4) with hyperlipemia (serum triglyceride concentration > 500 mg/dL) were reviewed. In all cases, hyperlipemia was a secondary complication of a primary systemic disease including septicemia, colitis, parasitism, esophageal obstruction, gastric impaction and rupture, fecalith, and pituitary adenoma. Therapy consisted of specific treatment for the primary disease, supportive care, and nutritional support. The mean time for resolution of hyperlipemia in cases requiring nutritional support (n = 6) was 7 days, and the duration of nutritional support in surviving patients was 11.7 days. Seven of 9 patients survived. The primary disease resulted in death in 2 patients. Enteral feeding with commercially prepared low residue diets and treatment of the primary disease was successful in reversing hyperlipemia in 5 of 6 surviving patients that required nutritional support. Parenteral administration of a glucose-based (non-lipid) solution was successful in resolving hyperlipemia in 1 patient.

We recorded pattern electroretinograms and visual evoked potentials in a group of selected patients with unilateral uncomplicated branch retinal vein occlusion. To document the effects of preexisting risk factors, patients were divided into three groups: diabetes mellitus, hypertension with hyperlipidemia and no systemic disease. The transient and steady-state pattern electroretinogram and visual evoked potential amplitudes were significantly reduced and visual evoked potential peak times were delayed relative to the fellow eyes and age-matched normal subjects. There was a second amplitude reduction relative to the other patient groups in both the affected and fellow eyes of the diabetes mellitus group, which was indicative of an additive effect of diabetes mellitus.

Atherosclerosis of the carotid bifurcation is an observable sign of systemic disease driven by key risk factors and resulting in an epidemic of stroke, myocardial infarction, and vascular death worldwide. Aggressive integrative preventive interventions of controlling hypertension, hyperlipidemia, diabetes mellitus, smoking, systemic inflammation/infarction, depression, and hyperhomocyst(e)imia are needed in the medical management of these high-risk patients. Surgical indications for asymptomatic surgery may be recalled through the acronym CAROTID, which emphasizes knowledge of risk benefit to a particular patient, adequate disclosure, and physician--patient equipoise.

Diabetes mellitus is a systemic disease with several major complications affecting both the quality and length of life. One of these complications is periodontal disease (periodontitis). Periodontitis is much more than a localized oral infection. Recent data indicate that periodontitis may cause changes in systemic physiology. The interrelationships between periodontitis and diabetes provide an example of systemic disease predisposing to oral infection, and once that infection is established, the oral infection exacerbates systemic disease. In this case, it may also be possible for the oral infection to predispose to systemic disease. In order to understand the cellular/molecular mechanisms responsible for such a cyclical association, one must identify common physiological changes associated with diabetes and periodontitis that produce a synergy when the conditions coexist. A potential mechanistic link involves the broad axis of inflammation, specifically immune cell phenotype, serum lipid levels, and tissue homeostasis. Diabetes-induced changes in immune cell function produce an inflammatory immune cell phenotype (upregulation of proinflammatory cytokines from monocytes/polymorphonuclear leukocytes and downregulation of growth factors from macrophages). This predisposes to chronic inflammation, progressive tissue breakdown, and diminished tissue repair capacity. Periodontal tissues frequently manifest these changes because they are constantly wounded by substances emanating from bacterial biofilms. Diabetic patients are prone to elevated low density lipoprotein cholesterol and triglycerides (LDL/TRG) even when blood glucose levels are well controlled. This is significant, as recent studies demonstrate that hyperlipidemia may be one of the factors associated with diabetes-induced immune cell alterations. Recent human studies have established a relationship between high serum lipid levels and periodontitis. Some evidence now suggests that periodontitis itself may lead to elevated LDL/TRG. Periodontitis-induced bacteremia/endotoxemia has been shown to cause elevations of serum proinflammatory cytokines such as interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), which have been demonstrated to produce alterations in lipid metabolism leading to hyperlipidemia. Within this context, periodontitis may contribute to elevated proinflammatory cytokines/serum lipids and potentially to systemic disease arising from chronic hyperlipidemia and/or increased inflammatory mediators. These cytokines can produce an insulin resistance syndrome similar to that observed in diabetes and initiate destruction of pancreatic beta cells leading to development of diabetes. Thus, there is potential for periodontitis to exacerbate diabetes-induced hyperlipidemia, immune cell alterations, and diminished tissue repair capacity. It may also be possible for chronic periodontitis to induce diabetes.

Atheromatous embolism is a systemic disease resulting from cholesterol crystal embolization in many organs, including the kidneys. To characterize atheroembolic renal disease (AERD), we retrospectively evaluated 11 patients with acute renal failure after vascular surgery, vascular radiology investigations, and anticoagulation at Miyazaki Medical College from 1994 to 2001. The diagnosis of cholesterol atheromatous embolism was confirmed by tissue examination or clinical grounds. The patients were all elderly men (average age of 66.8 years) with a history of hypertension (55%), diabetes mellitus (45%), hyperlipidemia (45%), and coronary artery disease (18%). Seven patients had livedo reticularis, and 4 had blood eosinophilia. Clinically, 7 patients were managed conservatively and 5 of them improved, whereas 4 patients required dialysis and developed chronic renal failure or died. The serum creatinine levels of the improved patients were significantly lower (1.28+/-0.3 mg/dl, p < 0.005) than the non-improved ones (7.70+/-3.6). The number of eosinophils was significantly higher in the improved patients (576+/-295 /ml, p < 0.05) than in the non-improved ones (208+/-206). However, no significant difference was observed in the levels of serum cholesterol and C-reactive protein among these patients. Since the population at risk for AERD is growing, we should recognize this disease as a cause of acute renal failure.

Atherosclerosis is a systemic disease that can ultimately lead to ischaemia and infarction in the heart, brain and peripheral vasculature. According to the "response to injury" hypothesis, endothelial dysfunction is the early event that allows penetration of lipids and inflammatory cells into the arterial wall, contributing to the development of the atherosclerotic lesion. Endothelial dysfunction is causally related to a variety of risk factors for atherosclerosis, including hyperlipidaemia and hypertension. Agents that restore endothelial function and NO bioavailability have beneficial anti-atherogenic activities and can improve cardiovascular outcomes; this has been observed with angiotensin-converting enzyme (ACE) inhibitors, statins and certain dihydropyridine-type calcium channel blockers (CCBs). In the Prospective Randomised Evaluation of the Vascular Effects of Norvasc Trial (PREVENT), the CCB amlodipine provided significant clinical benefits compared with placebo, including a marked reduction in cardiovascular morbidity and a reduction in the progression of carotid atherosclerosis. As these beneficial effects of amlodipine have not been observed with other dihydropyridine-type CCBs, it has been proposed that this agent has distinct anti-atherosclerotic properties related to its strong lipophilicity and membrane location. Experimental support for this hypothesis has been obtained from various in vitro and in vivo models of atherosclerosis. These findings support a broader therapeutic role for third-generation dihydropyridine-type CCBs in the treatment of atherosclerosis.
