The relationship between carotid and coronary calcification in patients with coronary artery disease.

BACKGROUND: Atherosclerosis is a multi-system pathology with heterogeneous involvement. We aimed to investigate the relationship between the presence and severity of carotid and coronary calcification in a group of patients with coronary artery disease. METHODS: Sixty-three patients presenting with unstable angina or positive stress test for myocardial ischaemia were enrolled in this study. All patients underwent CT scanning of the carotid and coronary arteries using the conventional protocol and Agatston scoring system. Risk factors for atherosclerosis were also analyzed for correlation with the extent of arterial calcification. RESULTS: Total coronary artery calcium score (CAC) was several times higher than total carotid calcium score (1274 (1018) vs 6 (124), p = 0·0001, respectively). The left carotid calcium score correlated strongly with the right carotid calcium score (rho = 0·69, p < 0·0001). The total CAC score correlated modestly with the total carotid calcium score (rho = 0·34, p = 0·007), in particular with left carotid score (rho = 0·38, p = 0·002), but not with the right carotid score. The left coronary calcium score correlated with the right coronary calcium score (rho = 0·35, p = 0·004), left carotid calcium score (rho = 0·33, p = 0·007) and left carotid calcium score at the bifurcation (rho = 0·34, p = 0·006). While hypertension correlated with carotid calcium score, diabetes and dyslipidaemia correlated with left CAC score. CONCLUSION: In patients with coronary disease, the carotid calcification pattern appeared to be similar between the right and left system in contrast to that of the coronary arteries. CAC correlated only modestly with the carotid score, despite being significantly higher. Hypertension was related to carotid calcium score while diabetes and dyslipidaemia correlated with coronary calcification.

Effect of surveillance for hepatocellular carcinoma on tumor staging and treatment decisions in Egyptian patients.

PURPOSE: Egyptian hepatocellular carcinoma (HCC) patients present at advanced stages. We aimed to study the influence of surveillance versus non-surveillance on HCC staging and the potential therapeutic options. METHODS: A retrospective study to evaluate the effect of surveillance on early detection of HCC among cirrhotic patients from 2003 to 2008. Patients examined every 6 months using ultrasound and α-fetoprotein (α-FP) (group A) and those diagnosed with those that present for the first time symptomatically or incidentally (group B). Groups were compared for α-FP level, tumour characteristics, severity of liver disease; tumour staging was evaluated by Okuda, CLIP and BCLC staging systems, in addition to the potential therapeutic options. RESULTS: Group A comprised 122 HCC cases and group B 473. Surveillance improved HCC detection: at the stage of single nodule in 62.3% in group A versus 52.2% in group B, (P = 0.046) and reduced the percentage of HCC with portal vein thrombosis in 16.4 versus 33.8%, (P = 0.000) and the percentage of α-FP >400 ng/ml in 19.5 versus 32.6%, (P = 0.006) in groups A and B, respectively. Surveillance doubled the detection of HCC at early stage of BCLC (25.4 vs. 11.9% P = 0.000) and doubled the patients' chance for loco-regional ablation (12.3 vs. 5.9%, P = 0.015) and liver transplantation (10.7 vs. 3.2%, P = 0.001) in groups A and B, respectively. CONCLUSION: HCC surveillance increases early detection of HCC and doubled the chances for curative options. Implementation of both HCC surveillance and cadaveric liver transplantation programs should be recommended in Egypt.
