A case of intraosseous xanthoma in a patient with a normal lipid profile is reported. Hyperlipidemia is present in most patients with xanthomas. Intraosseous xanthomas are rare, particularly in normolipidemic patients, in whom the presenting symptom is pain without skin lesions. A lytic lesion with a rim of sclerosis is seen on radiographs. Histology shows foam cells, giant cells, and fibrosis. Intraosseous xanthoma is a benign tumor, and other diagnoses must be ruled out (histiocytosis X, Erdheim Chester disease, clear cell carcinoma metastasis). Surgical excision of the lesion is the elective treatment.

Peripheral arterial disease affects at least 10% of adults older than 70 years. Risk factors such as diabetes, hypertension, hyperlipidemia, history of smoking, and genetics increase the incidence of the disease. Intermittent claudication, experienced as calf pain or cramping, is the primary symptom in patients with lower-extremity peripheral arterial disease. Patients with claudication are unable to walk even moderate distances. As a result, they often lead lives that are profoundly restricted. Medical therapeutic options available for patients with intermittent claudication are limited to a small number of medications and walking exercise rehabilitation. Walking exercise training can significantly increase ability and decrease calf discomfort for many patients. Nurses can have a major impact on improving the quality of life of patients with claudication, not only by seeking referrals to established institutional walking exercise programs, but also by helping patients in the community develop a personalized walking program. In this article, a nursing plan of care including short-term and long-term goals is addressed. A case study will illustrate the effectiveness and improved quality of life that an individualized program of walking exercise had for one community-based client.

In a prospective study the perioperative results of plug-and-patch repair were investigated in patients > or = 65 years, and quality of life was assessed using the SF36 preoperatively and 3 months after the procedure in 34 consecutive patients. From August 1994 to February 1999 147 patients with a mean age of 73 +/- 5 years (65-92 years) were operated on using the plug-and-patch technique, mostly under local anesthesia (LA: n = 124, 84%, ITN: n = 23, 16%). Preoperative risk factors were alcohol consumption, hypertonus, diabetes mellitus, ischemic heart disease, smoking, cerebrovascular disease, hyperlipidaemia and pulmonary disease. Most of the patients were ASA II (ASA I: n = 14, 9%, ASA II: n = 82, 56%, ASA III: n = 51, 35%). No intraoperative complications occurred, postoperative complications consisted of superficial wound hematoma (n = 6, 3.7%) and infection (n = 1, 0.6%), seroma (n = 7, 3.8%), urinary retention (n = 3, 1.8%) and ilioguinal pain syndrome (n = 3, 3.8%). The total amount of postoperative analgesic consumption was 4.9 +/- 1.8 g Novalgin for about 4 +/- 3 days. The duration of postoperative hospitalization was 2 +/- 1 days and limitation of daily activities 6 +/- 3 days. Clinical examinations after 3 months revealed no recurrence or late complications. Investigation of quality of life showed a significant improvement in the SF36 domains of physical activity, pain, vitality, and social functioning after the operation. No significant change was observed for physical, emotional, and global health.

Diabetic polyneuropathy is the most frequent neuropathy in western countries. In Germany, there are 3.5 to 4 million diabetic patients. Diagnosis should rule out other polyneuropathies and assess two out of the five diagnostic criteria: neuropathic symptoms, neuropathic deficits, pathological nerve conduction studies, pathological quantitative sensory testing and pathological quantitative autonomic testing. So far, the pathophysiology of diabetic neuropathy remains to be fully understood. Among the various pathophysiological concepts are the Sorbitol-Myo-Inositol hypothesis attributing Myo-Inositol depletion to the accumulation of Sorbitol and Fructose, the concept of deficiency of essential fatty acids with reduced availability of gamma-linolenic-acid and prostanoids, the pseudohypoxia- and hypoxia-hypothesis attributing endothelial and axonal dysfunction and structural lesions to increased oxidative stress and free radical production. Obviously, the hyperglycemia induced generation of advanced glycation end products (AGEs) also contributes to structural dysfunctions and lesions. Elevated levels of circulating immune complexes and activated T-lymphocytes as well the identification of autoantibodies against vagus nerve or sympathetic ganglia support the concept of an immune mediated neuropathy. The reduction of neurotrophic factors such as nerve growth factor, neurotrophin-3 or insulin-like growth factors also seems to further diabetic neuropathy. The symmetrical, distally pronounced and predominantly sensory neuropathy is far more frequent than the symmetrical neuropathy with predominant motor weakness or the asymmetrical neuropathy. The painless neuropathy manifests with impaired light touch sensation, position sense, vibratory perception and diminished or absent ankle deep tendon reflexes. The painful sensory diabetic neuropathy primarily affects small nerve fibers and accounts for decreased temperature perception and paresthesias. The proximal, diabetic amyotrophy evolves subacutely or acutely, induces motor weakness of the proximal thigh and buttock muscles and is painful. Cranial nerve III-neuropathy is also painful and has an acute onset. Truncal radiculopathy follows the distribution of truncal roots and frequently causes intense pain. Autonomic neuropathy occurs with and without somatic neuropathy. The most important therapy is to attempt optimal blood glucose control, to reduce body weight and hyperlipidemia. Symptomatic therapy includes alpha-lipoic acid treatment, as the antioxidant seems to improve neuropathic symptoms. Aldose reductase inhibitors might reduce sorbitol and fructose production and normalize myo-inositol levels. However, there are no aldose reductase inhibitors available in Europe as yet. Evening primrose oil, containing gamma-linolenic acid, might improve nerve conduction velocities, temperature perception, muscle strength, tendon reflexes and sensory function. Substitution of nerve growth factor showed promising results in pilot studies but failed in a large-scale multicenter study. Symptomatic pain treatment can be achieved with tricyclic antidepressants, selective serotonin reuptake inhibitors, anticonvulsants such as carbamazepine, gabapentin or lamotrigine, or anti-arrhythmic drugs such as mexiletine. Topical capsaicin application should reduce neuropathic pain but also induces local discomfort in the beginning of therapy. Vasoactive substances, so far have not proven to be of major benefit in diabetic neuropathy. Physical therapy and thorough footcare are of primary importance and allow prevention of secondary complications such as foot amputations.

Acute pancreatitis and eruptive xanthomata are the only recognised direct complications of severe hypertriglyceridaemia, although peripheral neuropathy has been described in patients with hyperlipidaemia. We describe a patient with mixed hyperlipidaemia presenting with severe scalp pain and eruptive xanthomata. Both resolved with treatment. We suspect that high triglyceride concentration can affect the function of sensory nerve fibres.

Peripheral arterial disease (PAD) is caused by atherosclerosis, the leading cause of death and disability in patients age 50 and older. PAD progresses gradually and silently over many years, occluding the lumen of arteries that supply blood to the extremities. Symptoms of peripheral arterial insufficiency include intermittent claudication, rest pain, and impotence. Nonoperative management--including the control of risk factors such as hypertension, diabetes, hyperlipidemia, and smoking--is the most effective method to lower the risk of morbidity from PAD. Diagnostic technologies such as color duplex imaging, MRI, and MRA complement the clinical assessment of PAD and provide a stronger foundation for treatment decisions in the primary care setting.

Two patients developed osteonecrosis, respectively one and two years after the short-term intravenous use of dexamethasone. A 35-year-old man received 150 mg over a period of 3 weeks associated with a craniotomy for a subarachnoidal haemorrhage. He developed bilateral osteonecrosis of the femoral and humeral heads, which necessitated bilateral hip replacement surgery. He still experiences pain in both shoulders. A 45-year-old woman received 42.5 mg over a period of 1 week as a treatment for reflex dystrophy with oedema. She developed bilateral osteonecrosis in the femoral condyles, the talus and the calcaneus and after treatment she continued to experience pain in her right knee and ankle whilst walking. The only other risk factor for osteonecrosis identified in these patients was hyperlipidaemia in the man. Corticosteroid-induced osteonecrosis is typically multifocal and usually occurs 0.5 to 3 years after the therapy was initiated. There is a relationship with the dose and length of therapy. Even the short-term use of corticosteroids for 3 weeks or less, may lead to this dehabilitating complication.

In the new guidelines from the Swedish Medical Products Agency, an aggressive approach is recommended for the treatment of hyperlipidemia in all patients with manifest atherosclerotic disease. Patients with intermittent claudication should therefore receive lipid-lowering treatment on the same indications as patients with coronary artery disease. The present article reviews our knowledge of hyperlipidemia as a risk factor for the development of peripheral artery disease. Hyperlipidemia is frequently found in these patients and the most common lipid derangements are low levels of HDL-cholesterol and hypertriglyceridemia. Hard end-point data concerning morbidity and mortality during lipid-lowering treatment in this specific population is largely lacking, although previous studies indicate that lipid-lowering treatment slows the atherosclerotic process and induces pain relief.

Demographic, clinical and laboratory data were retrospectively collected from records of 146 cases of CT fluoroscopy-guided chemical lumbar sympathectomy for the palliation of inoperable peripheral vascular disease (PVD) between January 1997 and August 1999. Of these, 16% had claudication, 39% had rest pain and 44% had ischaemic ulcers or gangrene. Seventy-three percent of elective cases were outpatients. At 3 months, 27 cases were lost to follow up, leaving 119 cases. Within 3 months, improvement, defined as doubling of the walking distance, cessation of rest pain or healing of ulcers, occurred in 30.3% of cases. No change was observed in 45.4% of cases and 24.3% of cases deteriorated. Patients with ulcers or gangrene had significantly poorer results than those without any ischaemic lesions, as only 19% versus 39% of patients improved (P < 0.05). The presence of hypertension, diabetes mellitus, hyperlipidaemia and smoking had no value in predicting clinical outcome (P > 0.05). There were no major complications noted. CT fluoroscopy-guided chemical lumbar sympathectomy is safe and effective, with a complication rate of less than 1%, and efficacy of at least 30% measured within 3 months. It is a simple and minimally invasive procedure, easily performed on an outpatient basis. CT fluoroscopy-guided chemical lumbar sympathectomy should be considered for all patients in the early stages of inoperable PVD.

Although treatment of children infected with HIV with protease inhibitors has improved the survival of these patients, various adverse side effects have been reported, including metabolic abnormalities, such as hyperlipidaemia. We describe a case of hip osteonecrosis in an adolescent with AIDS who was being treated with protease inhibitors. There is a possible relation with hyperlipidemia. F.M.G., white, 11 years old, AIDS A2, started to receive AZT and DDI when he was 7 years old. In April 1999, the patient had a significant increase in viral load and so the antiretroviral therapy was switched to d4T, 3TC and Ritonavir. Triglyceride plasma levels reached 460mg/dl after this switch and were always above the reference value. In December 1999, the patient complained of pain in the right hip. On physical examination, he had limited movement of this joint. Magnetic resonance imaging of the right hip showed flattening, deformity and fragmentation of the femoral head, compatible with osteonecrosis. Few cases of femoral head osteonecrosis have been associated with HIV infection, in the absence of the classic risk factors for osteonecrosis. Metabolic risk factors include hypertriglyceridaemia. The immunological disorders that occur in the HIV infection may predispose the patient to avascular osteonecrosis and metabolic disorders, particularly hypertriglyceridemia, while the use of protease inhibitors, may be considered an additional risk factor for osteonecrosis. Given the importance of premature diagnosis and to avoid complications of osteonecrosis, we recommend evaluation of musculoskeletal symptoms in children receiving protease inhibitors.
