A geographic information system was used in an epidemiological study of measles in Istanbul, Turkey. The aim was to obtain more reliable results and to increase the facilities for spatial monitoring in epidemiological studies. The Gaziosmanpasa district of Istanbul was selected as it experiences the highest level of migration, and currently has the highest population growth rate of the city's districts. The epidemic distribution of measles was investigated on the basis of examination of 320 children. The number, geographical distribution, complications and time of measles outbreaks were analysed and represented in thematic maps (a small selection is shown in this paper). The results were evaluated and, in view of these results, new vaccination plans were arranged. 相似文献

Objectives
Our aim was to evaluate congenital left ventricular wall abnormalities (clefts, aneurysms and diverticula), describe and illustrate imaging features, discuss terminology problems and determine their prevalence detected by cardiac CT in a single center.Materials and methods
Coronary CT angiography images of 2093 adult patients were evaluated retrospectively in order to determine congenital left ventricular wall abnormalities.Results
The incidence of left ventricular clefts (LVC) was 6.7% (141 patients) and statistically signi?cant difference was not detected between the sexes regarding LVC (P = 0.5). LVCs were single in 65.2% and multiple in 34.8% of patients. They were located at the basal to mid inferoseptal segment of the left ventricle in 55.4%, the basal to mid anteroseptal segment in 24.1%, basal to mid inferior segment in 17% and septal–apical septal segment in 3.5% of cases. The cleft length ranged from 5 to 22 mm (mean 10.5 mm) and they had a narrow connection with the left ventricle (mean 2.5 mm). They were contractile with the left ventricle and obliterated during systole. Congenital left ventricular septal aneurysm that was located just under the aortic valve was detected in two patients (0.1%). No case of congenital left ventricular diverticulum was detected.Conclusion
Cardiac CT allows us to recognize congenital left ventricular wall abnormalities which have been previously overlooked in adults. LVC is a congenital structural variant of the myocardium, is seen more frequently than previously reported and should be differentiated from aneurysm and diverticulum for possible catastrophic complications of the latter two. 相似文献75.

AIMS: The purpose of this study was to examine the proportion of general practitioner (GP) referrals to a hospital Respiratory Medicine clinic which might be suitable for a General Practitioner with a Special Interest (GPwSI) Respiratory Clinic. METHOD: All GP referral letters to the Respiratory Medicine Department of a teaching hospital, apart from urgent cancer referrals, were identified from two two-week periods. All patient and practice identifications were removed. Two GPs and one Consultant Respiratory Physician assessed each of the anonymised referral letters to determine the patient's suitability to be seen in a GPwSI Respiratory Clinic, assuming such a clinic had a predetermined range of investigative facilities. RESULTS: Out of 96 referrals covering a wide range of respiratory conditions apart from lung cancer, 22 (23%) were considered by all assessors to be suitable for a GPwSI clinic, and there was full agreement that 40 referrals (42%) were unsuitable. The other 34 referrals (35%) had varying degrees of agreement on suitability. The largest groups of patient referrals considered suitable for a GPwSI clinic were those with chronic obstructive pulmonary disease (COPD) or cough as the main presenting clinical problem. The commonest groups considered unsuitable were referrals of patients with an abnormal chest radiograph, haemoptysis, or possible interstitial lung disease. CONCLUSION: This small study has shown that at least a fifth of GP referrals to a hospital Respiratory Medicine clinic could be seen in a suitably resourced GPwSI clinic, with consequent reductions in hospital outpatient waiting lists and improved accessibility for patients. This finding will be of interest to potential commissioners of GPwSI services especially with the advent of Practice-based Commissioning. 相似文献
