Gouty arthritis, a common source of pain and disability, is the most common form of inflammatory arthritis affecting older people. The authors review the epidemiology and pathogenesis of hyperuricemia and gout, as well as the clinical forms of gouty arthritis. Gout is part of a clinical spectrum of conditions (obesity, diabetes mellitus, hyperlipidemia, coronary artery disease) and need for better patient education on management of these associated conditions is emphasized. The general algorithm of gout management is presented. Clinical particularities of gout presentation in older patients (increased incidence in women, polyarticular onset with hand involvement, earlier development of tophi, association with use of diuretics) are reviewed. Barriers against an optimal control of gout include lack of patient education, presence of comorbid conditions, particularly renal impairment, use of multiple drugs such as diuretics, and cognitive decline. Gout management in older adults remains unsatisfactory.

Euonymus alatus (EA), known as a Gui Jeon Wu in China, has been used as a folk medicine for regulating blood circulation, relieving pain, eliminating blood clot, and treating dysmenorrhea in Asian countries. Although EA has anecdotally ascertained to show the anti-hyperglycemic activity by enhancing insulin secretion, there is no sufficient experimental evidence for anti-hyperglycemic activity of EA. The purpose of this study was to investigate the preventive effect of 50% ethanol extract of EA in high-fat diet-induced hyperglycemic and hyperlipidemic ICR mice. At 6 week old, the ICR mice were randomly divided into five groups; two control and three treatment groups. The control mice was to receive either a regular diet (RD) or high-fat diet (HFD), and the treatment groups were fed a high-fat diet with either 350, 700 mg/kg of EA (EA350 and EA700) or 250 mg/kg of metformin (MET250) for a 10-week period. EA not only reduced body weight in a dose dependent manner, but also corrected associated hyperinsulinemia and hyperlipidemia. EA exerted beneficial effects on glucose and lipid homeostasis in diabetes that are not secondary to its ability to decrease food intake but its specific effects on hepatic lipogenesis related genes (SREBPla, FAS, GAPT) and PPAR-gamma gene expression in periepididymal fat. Taken together, the combined effect of EA to reduce plasma glucose and lipid levels, and reduce the deposition of triglyceride in the liver are indicative of a marked improvement in obesity-related diabetes and non-alcoholic fatty liver disease.

Propofol is a potent lipophilic anesthetic that was initially formulated in Cremophor El for human use. Because of the occurrence of Cremophor EL anaphylaxis and improvements in the quality of lipid emulsions, it was ultimately brought to market as 1% propofol formulated in 10% soybean oil emulsion. Emulsions represent complex formulation compositions whose suitability for intravenous administration is dependent on a number of factors. Despite the success of propofol emulsions, drawbacks to such formulations include inherent emulsion instability, injection pain, a need for antimicrobial agents to prevent sepsis, and a concern of hyperlipidemia-related side effects. Efforts to overcome such drawbacks have involved the development of propofol emulsions with altered propofol and lipid contents, the addition of different excipients to emulsions for antimicrobial activity, and study of nonemulsion formulations including propofol-cyclodextrin and propofol-polymeric micelle formulations. In addition, a number of propofol prodrugs have been made and evaluated.

Peripheral arterial disease (PAD), a major cause of disability, loss of work, and lifestyle changes in the United States, is defined as obstruction of blood flow into an arterial tree excluding the intracranial or coronary circulations. PAD is mostly silent in its early stages, but when lesion obstruction exceeds 50%, it may cause intermittent claudication with ambulation. Further disease progression typically leads to rest pain or frank tissue loss. However, some patients may remain asymptomatic with severe disease because of extensive collateralization in the lower extremity. Estimates of the prevalence of intermittent claudication vary by population, from 0.6% to nearly 10%; the rate increases dramatically with age. Approximately 20% to 25% of patients will require revascularization, while fewer than 5% will progress to critical limb ischemia. Limb loss, although rare, is associated with severe disability and an overall poor prognosis, with 30% to 40% mortality in the first 24 months after limb loss. As with coronary artery disease, the most common cause of symptomatic obstruction in the peripheral arterial tree is atherosclerosis, a systemic inflammatory process in which cholesterol-laden plaque builds up in the artery and eventually blocks the lumen. Typical risk factors include age, gender, diabetes, tobacco abuse, hypertension, and hyperlipidemia.

A 41-year-old man with hypertension and hyperlipidemia who complained of left hemiparesis after a temporal headache was admitted to our hospital. A cervical MRI with gadolinium enhancement revealed an intramural hematoma is compatible with right extracranial internal carotid artery dissection. Two weeks later, he complained of sudden onset of pain in the right side of his neck. The right extracranial internal carotid artery dissection followed by the right extracranial vertebral artery dissection was diagnosed. Spontaneous cervical artery dissection (SCAD) is one of the causes of stroke in young adults. The pathogenesis of SCAD remains unknown. Minor trauma like an excessive sneeze, migraine, and connective tissue disorders such as fibromuscular dysplasia and Ehlers-Danlos syndrome are well-known as risk factors for SCAD. Pathologically skin collagen abnormalities have been seen in German patients with SCAD without clinical evidence for any specific connective tissue disorder. We examined the ultrastructural morphology of the Japanese patient's dermal connective tissue components by electron microscopy. The patient's collagen fibers contained fibrils with highly variable diameters, and there were other ultrastructural abnormalities, including flower-like fibrils and large-diameter composite fibrils. This is the first report of a case of ultrastructural abnormalities of dermal connective tissue in a Japanese patient with SCAD.

Peripheral vascular disease is a manifestation of systemic atherosclerosis that leads to significant narrowing of arteries distal to the arch of the aorta. The most common symptom of peripheral vascular disease is intermittent claudication. At other times, peripheral vascular disease leads to acute or critical limb ischemia. Intermittent claudication manifests as pain in the muscles of the legs with exercise; it is experienced by 2 percent of persons older than 65 years. Physical findings include abnormal pedal pulses, femoral artery bruit, delayed venous filling time, cool skin, and abnormal skin color. Most patients present with subtle findings and lack classic symptoms, which makes the diagnosis difficult. The standard office-based test to determine the presence of peripheral vascular disease is calculation of the ankle-brachial index. Magnetic resonance arteriography, duplex scanning, and hemodynamic localization are noninvasive methods for lesion localization and may be helpful when symptoms or findings do not correlate with the ankle-brachial index. Contrast arteriography is used for definitive localization before intervention. Treatment is divided into lifestyle, medical, and surgical therapies. Lifestyle therapies focus on exercise, smoking cessation, and dietary modification. Medical therapy is directed at reducing platelet aggregation. In addition, patients with contributing disorders such as hypertension, diabetes, and hyperlipidemia need to have these conditions managed as aggressively as possible. Surgical therapies include stents, arterectomies, angioplasty, and bypass surgery.

We report two cases of heterozygous Fabry disease with severe organ damage. Case 1 was a 47-year-old woman. In April 1977, at the age of 27 years, she had proteinuria and edema around the 26th week of her second pregnancy and was diagnosed as toxicosis of pregnancy. She had proteinuria after the delivery. In 1990, a renal biopsy showed zebra bodies under electron microscopic findings, and the patient was diagnosed as Fabry disease. In 1998, a myocardial biopsy showed identical findings. The patient developed severe hypertension and decreased renal function, and alpha-galactosidase enzyme replacement therapy was initiated. However, despite treatment, she was started on dialysis in 2004. Case 2 was a 40-year-old woman. In March 2003, the patient presented with severe hypertension. The patient had cerebral infarction, cardiac hypertrophy, old myocardial infarction and renal failure without diabetes mellitus, hyperlipidemia and collagen disease. The patient was diagnosed as Fabry disease from persistent numbness and pain in the four extremities, a family history of mortality due to heart disease, and skin biopsy findings. She is currently undergoing enzyme replacement therapy. It is generally known that female Fabry disease patients are asymptomatic or mildly symptomatic, as were the present two patients, but some can have marked organ disorders. Hence, even in female patients, it is necessary to consider Fabry disease as a causative disease of chronic renal failure.

A 54-year old man with a family history of hyperlipidemia was admitted with a 12 h history of severe generalized abdominal pain associated with nausea, vomiting and abdominal distension. Examination of the abdomen revealed tenderness in the periumblical area with shifting dullness. Serum pancreatic amylase was 29 IU/L and lipase 44 IU/L, triglyceride 36.28 mmol/L. Ultrasound showed ascites. CT of the abdomen with contrast showed inflammatory changes surrounding the pancreas consistent with acute pancreatitis. Ultrasound (US) guided abdomen paracentesis yielded a milky fluid with high triglyceride content consistent with chylous ascites. The patient was kept fasting and intravenous fluid hydration was provided. Meperidine was administered for pain relief. On the following days the patient's condition improved and he was gradually restarted on a low-fat diet, and fat lowering agent (gemfibrozil) was begun, 600 mg twice a day. On d 14, abdomen US was repeated and showed fluid free peritoneal cavity. The patient was discharged after 18 d of hospitalization with 600 mg gemfibrozil twice a day. At the time of discharge, the fasting triglyceride was 4.2 mmol/L. After four weeks the patient was seen in the clinic, he was well.

In our aging population, primary major amputations (AMP, below-knee or above-knee) continue to be performed despite advances in revascularization. We hypothesized that not only patient comorbidities but also the system of health-care delivery affected the treatment of patients with critical limb ischemia (CLI). A prospective analysis of patients presenting with CLI was undertaken to determine whether patient-specific factors or healthcare delivery factors (system-related) influenced treatment with primary AMP versus lower extremity revascularization (LER). The patient-specific factors age, gender, race/ethnicity, presence of coronary artery disease, cerebrovascular disease, tobacco use, diabetes mellitus (DM), dialysis dependence (end-stage renal disease, ESRD), hypertension, hyperlipidemia, stage of CLI (rest pain, minor or major tissue loss), history of revascularization, and functional status (living situation and ambulatory status) were recorded. The system-related factors time from onset of CLI to vascular surgery evaluation and type of insurance (managed care/other insurance) were also noted. The influence of patient-specific and system-related factors on the primary treatment modality (AMP versus LER) was determined with univariate and multivariate analyses. A total of 224 patients presented with CLI between March 1, 2001, and March 1, 2005. Patients were treated with primary major AMP in 97 cases (43%) and revascularization in 127 cases (57%). On univariate analysis, nonwhite race/ethnicity, DM, ESRD, major tissue loss, dependent living situation, and nonambulatory status were all significant predictors of AMP versus LER (all P < 0.01). On multivariate analysis, major tissue loss, ESRD, DM, and nonambulatory status remained independent predictors of AMP versus LER (all P < 0.05). The system-related factors of time to vascular surgery evaluation (mean 8.6 weeks, 7.1 vs. 9.3 weeks AMP versus LER, P = 0.60) and type of insurance (managed care, 17% vs. 24% AMP vs. LER, P = 0.15) had no influence on treatment. Fifty-four percent of all primary major AMPs were performed due to extensive gangrene or infection present at initial vascular evaluation which precluded limb salvage. Major tissue loss, ESRD, DM, and nonambulatory status are all independent predictors of treatment with primary AMP as opposed to revascularization. Treatment of CLI is determined by patient-specific factors and does not appear to be adversely influenced by system-related factors. Efforts toward improving limb salvage may be best directed at aggressive treatment of medical comorbidities to prevent the late complications of CLI. Earlier recognition of tissue loss and referral to the vascular specialist may lead to improved limb salvage.

Peripheral arterial disease (PAD) includes a wide range of manifestations in the lower limb, from asymptomatic to symptomatic disease ranging from intermittent claudication to critical limb ischemia, with ulcers, rest pain, or gangrene. It is manifestation of generalized atherosclerosis and this is clearly shown by the high prevalence of coexistence coronary and cerebral arterial disease in these patients. The cumulative findings on molecular and cellular biology have dramatically changed our concept of atherosclerotic disease. Recently, it has become clear that inflammation is fundamental to the process of atherosclerosis. Although the relation between inflammation and PAD is not well characterized, the emerging data demonstrated that PAD is a common manifestation of atherosclerosis that is associated with a systemic inflammation. The most important risk factors for PAD are similar to those of atherosclerotic disease elsewhere: age, male sex, diabetes mellitus, smoking, hypertension, hyperlipidemia, and hereditary factors. Serum levels of inflammatory markers, especially after exercise, have been found to be higher in patients with PAD than in controls, and associated with prognosis as well as restenosis in patients with PAD after revascularization. In the general United States adult population, inflammation is independently associated with PAD in a cross-sectional, nationally large representative sample. All of those evidences indicate that PAD is one aspect of atherosclerosis, a disease rationally connects with inflammation, which may further change our preventive and therapeutic strategies.
