Urine samples from 1000 pre-school children aged 4 weeks to 5 years, attending welfare centres, nursery schools or day nurseries in one London borough, were cultured by the dip-slide method. Five children had asymptomatic bacteriuria, a prevalence of 0-5 per cent. The need for screening the urine of pre-school children is discussed.

Seventeen patients with celiac artery stenosis causing abdominal angina or the development of collateral channels were studied. Of 7 patients with abdominal angina, 5 had celiac compression relieved by surgery and 2 had atherosclerosis. Most of the 10 asymptomatic patients were somewhat older, and none were operated upon. Angiographically, the stenosis was believed to be congenital in 3 and atherosclerotic in 7. Abundant collateral vessels were present in all asymptomatic patients. Since the angiographic appearances may be identical in patients with and without symptoms, careful clinical evaluation prior to surgical intervention is necessary.

PURPOSE: To assess the frequency of lower extremity deep venous thrombosis (DVT) detected with ultrasound (US) in patients with bilateral symptoms suggestive of DVT. MATERIALS AND METHODS: Fifty patients with bilateral lower extremity symptoms suggestive of DVT were examined prospectively for predisposing factors and type of symptoms. Charts were reviewed for previous lower extremity disease or chronic illness that could explain the patient's symptoms. The frequency of DVT diagnosed with US in this patient group was determined. RESULTS: No DVT was identified in the patients with bilateral symptoms suggestive of DVT. Retrospective review demonstrated that 34 (68%) of the patients had a preexisting condition (cardiac disease, venous insufficiency, chronic swelling, cellulitis or thrombophlebitis, peripheral arterial disease). Because compression US has a greater than 90% sensitivity and specificity for the diagnosis of DVT, these results were statistically significant (P < .001). CONCLUSION: The likelihood of DVT in patients with bilateral lower extremity symptoms is extremely low. Alternative causes should be carefully explored before lower extremity US is considered.

Non-invasive procedures to screen patients with asymptomatic carotid ar tery bruits for angiography and surgery are now available. The use of Oculople tysmography (OPG) and Phonoangiography (PA) in 1120 arteries in 560 patients is reviewed; 101 patients (18%) had positive findings. Eighty five of these patients were available for 5 year follow up. None of these patients had surgery or other treatment. In this group there were 27 (32%) major cerebro vascular accidents (CVA) and 22 deaths. In this group of patients, screening and further work up and surgery where indicated in advised.
