A routine system for monitoring perinatal deaths in Scotland.

Since 1983 the monitoring of perinatal deaths in Scotland has been incorporated into the established data collection system which monitors maternal and child health in Scotland. This paper describes the transition from a research project to the routine system and the extension of the data collection to include paediatric and pathological findings. This information is provided by local co-ordinators in active clinical practice. Baseline data are obtained from the routine maternity discharge document (SMR 2). A summary of the findings for the first 4 years of the study, 1977, 1979, 1980 and 1981 is presented, including information about birthweight and gestation-specific perinatal mortality rates; perinatal mortality rates by time of death in relation to labour and singleton and multiple perinatal mortality rates by the obstetric complication preceding the death.

Synovial plicae of the knee.

Synovial plicae are remnants of synovial tissue found in the adult knee which in early development partitioned the joint into three compartments. The most common types are the suprapatellar, medial patellar, and infrapatellar plicae. Although they are normally found in up to 60% of adult knees, plicae may become pathologically thickened and symptomatic, resulting in the "plicae syndrome." In addition, persistence of these structures in their embryonic form as complete septa may give rise to a variety of intra-articular compartmental syndromes, medial patellar, and infrapatellar plicae. Although they are normally found in up to 60% of adult knees, plicae may become pathologically thickened and symptomatic, resulting in the "plicae syndrome." In addition, persistence of these structures in their embryonic form as complete septa may give rise to a varietellar, medial patellar, and infrapatellar plicae. Although they are normally found in up to 60% of adult knees, plicae may become pathologically thickened and symptomatic, resulting in the "plicae syndrome." In addition, persistence of these structures in their embryonic form as complete septa may give rise to a variety of intra-articular compartmental syndromes. This report describes the anatomy and embryology of synovial plicae, as well as the clinical and radiographic findings associated with abnormal plicae in a variety of clinical entities.
