A test for space clustering and its application to congenital limb defects in Cardiff.
Several methods are currently available for investigation of low intensity space-time clustering (Knox, 1963, 1964; Ederer, Myers, and Mantel, 1964; David and Barton, 1966; Mantel, 1967; Pike and Smith, 1968.) Its presence usually indicates one of two causes-either an infection or a causal factor which is local in both time and space and experienced by each individual in the cluster. There are,...
متن کاملAn investigation of space and space-time clustering in a large sample of infants with neural tube defects born in Cardiff.
Altogether 406 infants with neural tube defects born in Cardiff between 1956-71 were investigated for evidence of space-time clustering and 100 similarly affected infants, together with matched controls born in Cardiff between 1964-66 were investigated for evidence of spatial clustering. No evidence of excessive prevalence in either dimension was observed.
متن کاملCIGARETTE SMOKE/ETHANOL-INDUCED LIMB DEFECTS IN MOUSE EMBRYOS
We have produced a spectrum of limb defects in developing mouse embryos by exposing the mother to smoke from cigarettes with different nicotine concentrations, ethanol, and a combination of ethanol and cigarette smoke. The critical time of exposure was determined to be during day 10 of gestation (vaginal plug=day 0). This time is prior to the critical events which occur between the apical e...
متن کاملPerforator Flaps for Reconstruction of Lower Limb Defects
BACKGROUND Reconstruction of soft tissue defects in the lower third of the leg remains challenging. Anatomical constraints limit the local options available for complex defects especially lower third of leg. Local flaps based on perforator vessels are raising interest in reconstructive surgery of the limbs. We present our experience with perforator flaps for reconstruction of soft tissue def...
متن کاملSpace-time clustering in infectious mononucleosis.
A good deal of work has been published in recent years on tests of space-time clustering applied to diseases of possible but unproved infectiousness. In particular, they have been used to test evidence suggestive of the infectivity of neoplastic conditions such as leukaemia and Burkitt's lymphoma. It seemed to us worth reporting the following rather unexpected results, obtained during a study o...
