Prevalence of diabetes and/or ischaemic heart disease in classes of increasing carotid artery atherosclerosis: an ultrasonographic study

DIABETIC MEDICINE, Issue 8 2003
S. Inchiostro
Abstract Aims To evaluate the prevalence of non-diabetic subjects and diabetic patients, with or without ischaemic heart disease (IHD), in different classes of increasing carotid atherosclerotic damage. Methods Using high-resolution B-mode ultrasound, we studied 598 subjects without known cardiovascular disease (CVD) or diabetes, 74 diabetic patients without CVD, 74 non-diabetic subjects with IHD and 36 patients with both diabetes and IHD. Carotid atherosclerosis was classified as: normal; thickened intima-media; non-stenotic plaque; stenotic plaque. Results Compared with subjects without diabetes or CVD, the frequency of patients with diabetes without known CVD increased significantly from ,normal' to ,stenotic plaque' (4.1%, 6.4%, 13%, 14.8% for normal, thickened intima-media, non-stenotic plaque and stenotic plaque, respectively; P = 0.0057). The same figures were 6%, 7.6%, 10.2%, 23.3% (P = 0.0007) for non-diabetic subjects with IHD, and 0%, 2%, 5.6%, 15.9% (P < 0.0001) for diabetic patients with IHD. No difference was found comparing subjects with diabetes without CVD with non-diabetic patients with IHD (P = 0.56). Using polychotomous logistic regression analysis, diabetic patients without CVD and non-diabetic subjects with IHD showed a similar association with the increasing degree of carotid atherosclerosis (P = 0.59), but significantly stronger compared with subjects without diabetes or CVD (P < 0.03 for both). Conclusions Diabetic patients without known CVD show an advanced degree of carotid atherosclerotic damage similar to non-diabetic subjects with IHD and significantly higher compared with non-diabetic subjects without CVD. Our data support the need for an aggressive early prevention of CVD in diabetic subjects. [source]

Prevalence and outcome of asymptomatic carotid stenosis: a population-based ultrasonographic study

EUROPEAN JOURNAL OF NEUROLOGY, Issue 4 2002
P. P. Mineva
The aims of this epidemiological population-based cohort study were to examine the prevalence and outcomes of asymptomatic carotid stenosis (ACS) detected by duplex scanning and its relations to other vascular risk factors. A total of 500 volunteers, 200 men and 300 women, without signs and symptoms of cerebrovascular disease, aged 50,79 years, were enrolled in the study. The prevalence of ACS of 50% or greater was 6.4%. Only severe carotid stenosis was detected in 0.4% of the subjects examined. Significant relationships between ACS and coronary heart disease (CHD) [odds ratio (OR)=8.00], peripheral arterial disease (PAD) (OR=3.66), cigarette smoking in men (OR=4.39) and obesity in women (OR=0.31) were found. The biennial incidence rate of cerebral ischaemic events was 9.4%. A progression of ACS was revealed in 14% and a regression in 6.25% of the subjects. The patients with progressing ACS to more than 70% diameter reduction reached the end-points. Follow-up with repeated duplex scans in patients with advancing ACS of 50% or greater, especially smokers with CHD and PAD, is recommended. [source]

Ciliated foregut cyst of the gallbladder: A case report and review of the literature

PATHOLOGY INTERNATIONAL, Issue 5 2000
Eun Sook Nam
A case is presented of a ciliated cyst of the gallbladder in a 36-year-old Korean woman which was incidentally found on ultrasonographic study. A cystic mass measuring 1.5 × 1 × 1 cm was found in the fundus of the gallbladder. The cyst was unilocular and intramural without communication to the lumen. Microscopically, the cyst wall was lined by a single layer of pseudostratified, ciliated, columnar epithelium and goblet cells with underlying smooth muscle layers. This was considered to be the cyst arising from the embryonic foregut and showing differentiation toward respiratory structures. The term ,ciliated foregut cyst of the gallbladder' is suggested here.

Ultrasonographic measurement of endometrial changes following discontinuation of tamoxifen treatment in postmenopausal breast cancer patients

Objective To assess whether there is a decrease in endometrial thickness following discontinuation of tamoxifen treatment as measured by ultrasound. Design Prospective study. Setting Department of Obstetrics and Gynaecology, Sapir Medical Centre, Kfar-Saba, Israel. Population Fifty-eight postmenopausal women with breast cancer who were treated with tamoxifen. Methods Transvaginal ultrasonographic measurements of endometrial thickness. Main outcome measures Evaluation of the changes of endometrial thickness and the frequency the endometrium reached a thickness of , 5 mm at different time intervals after stopping tamoxifen treatment. Results There was a significant decrease in median thickness of the endometrium, within six months after stopping tamoxifen, from 7.75 mm measured at the last ultrasonographic study performed before tamoxifen discontinuation down to 5.2 mm (P= 0.002). There were no further reductions in endometrial thickness, and it remained constantly low in subsequent ultrasonographic studies which were performed at various times up to 30 months following the discontinuation of tamoxifen treatment. While taking tamoxifen, only 25.9% of the women had an endometrial thickness of , 5 mm. This proportion doubled in their first six months after stopping. Conclusions Median thickness of endometrial thickness significantly reduced within six months following tamoxifen discontinuation, and remained constantly low thereafter. This finding may support use of ultrasonographic imaging for the measurement of tamoxifen's effect on the endometrium of postmenopausal breast cancer patients. [source]
