The infrarenal aorta was examined by ultrasound in 329 men who had lost a leg in World War II and in 702 war veterans. The groups were similar in terms of age and risk factors for arteriosclerosis. Abdominal aortic aneurysms were found in 5.8% of the amputees compared with 1.1% of the non-amputees. Unilateral flow reduction after leg amputation causes an asymmetrical flow pattern at the aortic bifurcation, and this is probably the main cause of late damage to the aorta.

A fine structure of blood flow through a curved vessel with an aneurysm was studied in in vitro experiments in relation to rheological factors of arterial diseases such as arteriosclerosis or thrombosis. On the basis of the in vivo data related to cerebral circulation, red blood cell suspension was flowed through curved vessel models with an asymmetrical aneurysm. Flow visualization was made with a microscope 16 mm cinecamera-TV monitor system, and the velocity profile was measured using the laser Doppler velocimeter. Vortices induced in aneurysm influenced flow structure and velocity at the presence of the secondary flow due to the vessel curvature. This suggests strongly that blood flow in curved arteries with an aneurysm must be understood under the influence of the secondary flow.

The Hutchinson-Gilford progeria syndrome (HGPS) is a very rare, but well known inherited condition of uncertain etiology in which features of premature and accelerated aging are mixed with those of delayed maturity and immaturity. Appearance at birth and birth weight are usually normal but growth typically slows after 1 year. All organ systems undergo degeneration to such an extent that the patient resembles an old man or woman. Short stature, micrognatia, alopecia, sculptured nose, prominent scalp veins, loss of subcutaneous fat, prominent joints, hyperlipidemia and early arteriosclerosis characterize the syndrome. Skeletal compromise includes hypoplasia and dysplasia, persistent open fontanelles, severe osteolysis and pathological fractures. There are no intellectual deficits in patients with this syndrome, and intelligence is unaffected. The life span in progeria is shortened by early arteriosclerosis. In this case, we review the characteristics of the severe osteolytic compromise in distal arms and limbs and bone deformities in a case of an 8-year-old girl, who was admitted to our hospital with short stature and loss of hair. On examination, the child had the major clinical criteria for HGPS as well as severe alterations in osteogenesis, including craniofacial disproportion, short and sculptured nose, delayed dentition, severe scoliosis, clavicular deformity and asymmetrical and hypoplastic arms and legs. Generalized osteopenia and severe osteolytic compromise in distal extremities were found by X-ray examination. In summary, we report the case of an 8-year-old girl who meets the diagnostic criteria for HGPS with severe involvement of her bones and joints with a review of the current literature and a possible therapeutic approach.

The endogenous nitric oxide-synthase inhibitor asymmetrical dimethyl-L-arginine (ADMA) is elevated in patients with increased risk for arteriosclerosis. Obesity is a risk factor for cardiovascular disease. We measured plasma ADMA concentrations in morbidly obese women before and after weight loss following gastroplastic surgery. ADMA and symmetrical dimethyl-L-arginine concentrations were analyzed by HPLC from 34 female patients (age 41 +/- 7 yr) with a body mass index (BMI) of 49 +/- 1 kg/m2 before and 14 months after vertical ring gastroplasty. Age-matched healthy women (BMI < 25 kg/m2; n = 24) were studied as controls. After gastroplastic surgery, BMI decreased to 34 +/- 1 kg/m2 in obese women (P < 0.00001), and ADMA concentrations were reduced from 1.06 +/- 0.06 micromol/liter at baseline to 0.81 +/- 0.04 micromol/liter after weight loss (P < 0.00001). Symmetrical dimethyl-L-arginine plasma levels were not affected. ADMA correlated with high-sensitivity C-reactive protein at baseline (r = 0.42; P < 0.05) and after weight loss (r = 0.56; P < 0.005). No association with blood pressure or plasma lipids could be observed. ADMA concentrations were lower in controls (0.68 +/- 0.04 micromol/liter; P < 0.05) compared with obese patients before or after weight reduction. The decrease of highly elevated ADMA concentrations in morbidly obese patients is paralleled by improvement of parameters associated with the metabolic syndrome after weight loss.

A 66-year-old Taiwanese aboriginal male had complained of right-side blurred vision for 2 months, especially when reading. He had a 10-year history of hypertension and cardiovascular disease. His best-corrected visual acuity was 20/25 in each eye. Ophthalmoscopy revealed asymmetrical cupping, but a normal disc. Humphrey perimetry showed an upper homonymous paracentral quadrantanopic defect. Brain magnetic resonance imaging showed an infarction in the left lower calcarine area over the extrastriate (V2/V3) cortical area and a narrowing of the left middle and posterior cerebral arteries due to severe arteriosclerosis.
