Healthy Nordic diet has been beneficially associated with CHD risk factors, but few studies have investigated risk of developing CHD. We investigated the associations of healthy Nordic diet with major CHD risk factors, carotid atherosclerosis and incident CHD in middle-aged and older men from eastern Finland. A total of 1981 men aged 42–60 years and free of CHD at baseline in 1984–1989 were investigated. Diet was assessed with 4-d food recording and the healthy Nordic diet score was calculated based on the Baltic Sea Diet Score. Carotid atherosclerosis was assessed by ultrasonography of the common carotid artery intima–media thickness in 1053 men. ANCOVA and Cox proportional hazards regression analyses were used for analyses. Healthy Nordic diet score was associated with lower serum C-reactive protein (CRP) concentrations (multivariable-adjusted extreme-quartile difference 0·66 mg/l, 95 % CI 0·11, 1·21 mg/l) but not with serum lipid concentrations, blood pressure or carotid atherosclerosis. During the average follow-up of 21·6 years (sd 8·3 years), 407 men had a CHD event, of which 277 were fatal. The multivariable-adjusted hazard ratios in the lowest v. the highest quartile of the healthy Nordic diet score were 1·15 (95 % CI 0·87, 1·51) for any CHD event (P trend 0·361) and 1·44 (95 % CI 0·99, 2·08) (P trend 0·087) for fatal CHD event. We did not find evidence that adherence to a healthy Nordic diet would be associated with a lower risk of CHD or with carotid atherosclerosis or major CHD risk factors, except for an inverse association with serum CRP concentrations.

Several studies have suggested that higher carotenoid levels may be beneficial for atherosclerosis patients, but few studies have examined this relationship in the Chinese population. This cross-sectional study examined the association between the levels of carotenoids in diet and serum and carotid intima–media thickness (IMT) in Chinese adults aged 50–75 years in Guangzhou, China. Dietary intake was assessed using a FFQ. HPLC was used to assay the serum concentrations of α-carotene, β-carotene, lutein+zeaxanthin, β-cryptoxanthin and lycopene. The IMT at the common carotid artery (CCA) and bifurcation of the carotid artery was measured by B-mode ultrasound. A total of 3707 and 2947 participants were included in the analyses of dietary and serum carotenoids. After adjustment for demographic, socio-economic and lifestyle factors, all the serum carotenoids levels except lycopene were found to be inversely associated with the IMT at the CCA and bifurcation (Ptrend<0·001 to 0·013) in both men and women. The absolute mean differences in the IMT between the subjects in the extreme quartiles of serum carotenoid levels were 0·034 mm (α-carotene), 0·037 mm (β-carotene), 0·032 mm (lutein+zeaxanthin), 0·030 mm (β-cryptoxanthin), 0·015 mm (lycopene) and 0·035 mm (total carotenoids) at the CCA; the corresponding values were 0·025, 0·053 0·043, 0·050, 0·011 and 0·042 mm at the bifurcation. The favourable associations were also observed between dietary carotenoids (except lycopene) and the CCA IMT. In conclusion, elevated carotenoid levels in diet and serum are associated with lower carotid IMT values (particular at the CCA) in Chinese adults.

A 25-year-old male developed a traumatic intimo-medial dissection and saccular pseudoaneurysm at the origin of the innominate artery following a motorcycle accident. On physical examination there was no perceivable trauma to the chest. In addition, there were no clinical symptoms that suggested this serious injury. The patient was managed with successful stent-graft placement on an elective basis.

Parapharyngeal abscess as a complication of cholesteatoma is an uncommon entity. Endopharyngeal common carotid artery rupture due to parapharyngeal abscess is also uncommon, and these cases usually end fatally. We present a 17-year-old male with parapharyngeal abscess due to cholesteatoma who developed an endopharyngeal common carotid blow out and survived after common carotid ligation without any neurological sequalae.

The cross-sectional area of the common carotid artery bulb was measured using a 5 MHz pulse wave Doppler probe in a patient undergoing general anaesthesia using a laryngeal mask airway (LMA). A simultaneous measurement of blood velocity was performed to allow determination of the blood flow. Following inflation of the cuff on the LMA, the cross-sectional area of the right carotid artery bulb decreased from 1.09 to 0.89 cm2, flow velocity increased 120 to 176 cm s−1 and the blood flow increased from 130.8 to 156.6 cm3 s−1. On the left the cross-sectional area decreased from 1.16 to 1.13 cm2, the velocity increased 136 to 151 cm s−1 and the blood flow increased from 157·8 to 170·6 cm3 s−1 . While a reduction in cross-sectional area was observed in the carotid bulb in this patient, this was accompanied by an increase in the velocity and a consequent increase in blood flow. In patients with atheromatous disease involving the carotid arteries this decrease in cross-sectional area may prove clinically significant. The use of the LMA may not be suitable for this population.
