Classical Description Logics (DLs) [2] cannot properly deal with the endemic imprecision of biomedical knowledge. For example, the current version of the SNOMEDCT ontology defines a “Perinatal Cyanotic Attack” as a cardiovascular disorder occurring in the perinatal period and manifested through cyanosis. This definition depends on two vague notions, namely the perinatal period—the period of tim...

The perinatal period is a time of high risk for women with unipolar and bipolar mood disorders. We discuss treatment considerations for perinatal mood disorders, including unipolar and bipolar depression as well as postpartum psychosis. We further explore the unique issues faced by women and their families across the full trajectory of the perinatal period from preconception planning through pr...

BACKGROUND There is a need to have uniformed reporting of perinatal mortality for births following assisted reproductive technology (ART) treatment to enable international comparison and benchmarking of ART practice. METHODS The Australian and New Zealand Assisted Reproduction Database was used in this study. Births of ≥ 20 weeks gestation and/or ≥ 400 grams of birth weight following embryos ...

Due to developmental immaturity of the central nervous system, effects of an adverse intrauterine environment and need for intensive care postnatally, preterm infants are at high risk of sustaining brain injury in the perinatal period. Infants who suffer brain injury in the perinatal period are at risk for long-term neurodevelopmental sequelae. Clinical and experimental data supports a signific...

Background: Despite advances in obstetrics and gynaecology, the perinatal mortality among twins still remains high. This study compares the perinatal outcome of first and second twin. Materials & Methods: A prospective study was conducted at Institute of maternal and Child Health, Calicut over a period of one year; 2005 to 2006. 200 (antenatal women with) twin pregnancies were followed up from ...

OBJECTIVES To determine the perinatal mortality rate among women who delivered through caesarean section in a tertiary health institution in Nigeria and evaluate how various social and obstetric factors influence the perinatal deaths. METHODS A review of the clinical records of patients who had caesarean section associated with perinatal death over a 5-year period in the University of Ilorin ...

Introduction: Perinatal mortality rate (PMR) is the most sensitive index of the health status of women and quality of maternal and child health services. Over 130 million babies are born every year, large numbers of children die soon after birth, many of them in the first 4 weeks of life (neonatal deaths) and most of them in the first week (early neonatal deaths). Objective: The objective of th...

Antepartum hemorrhage (APH) is a grave obstetrical emergency. It is leading cause of perinatal death . Aims of the present study were to study perinatal outcome in patients with antepartum hemorrhage. It is a prospective study carried out over a period of one year (2011-12) on 100 women admitted with the diagnosis of APH at Pt. B.D Sharma medical college, Rohtak, Haryana, India, a tertiary care...

BACKGROUND The purpose of this paper was to investigate how well children's health until age 7 years can be predicted by perinatal outcome using routine health registers. METHODS Follow-up of one year cohort (N = 60192) was performed by record linkages with personal identification number. The data came from the 1987 Finnish Medical Birth Register, from six other national registers and from ed...

The relationship between perinatal outcome and antenatal care was investigated at King Edward VIII Hospital, Durban, by a case control retrospective study of pregnancy records in 165 perinatal deaths and 156 infants surviving the perinatal period. 82% of the mothers of live infants had booked for antenatal care compared with only 60% of those who experienced a perinatal death. Hospital booking ...
