Infant mortality in Bremen in the 19th century

This article analyses the development of infant mortality in the port city of Bremen within a disaggregated framework, using the available material from civil birth and death registers, as well as the census returns for 1862, 1871, 1885, 1895, and 1905. The analysis focuses on a number of factors that affected infant mortality, including breast-feeding, female labor-force participation, social class, and migrant status. Particular attention is paid to the age structure of infant mortality in relation to stillbirths and reproductive mortality, as well as registered trends in neonatal and postneonatal mortality. The Bremen data also provide a basis for analyzing infant mortality by cause of death and seasonality. By incorporating disaggregated demographic and socioeconomic data, the authors are able to offer some new insights into the determinants of urban infant mortality trends in the 19th century.     

禽Ⅰ型副黏病毒各种禽源分离株对4种禽类的致病性

选取从临床感染禽Ⅰ型副黏病毒(APMV-1)的鸡、鹅、鸽、鹌鹑、珍珠鸡、孔雀、画眉鸟等7种禽类病例分离到的9个代表性毒株,分别对鸡、鹌鹑、鹅和鸽进行了人工感染试验。结果,除鸽源毒株gxp22对鸡和鹅无致病力外,其他8个分离毒株对鸡、鹌鹑和鹅都有较强的致病力,死亡率为60%~100%,试验鸡表现的症状和病理变化特征最明显,鹅的比较明显,鹌鹑的则最不明显;3个鸽源分离株对鸽的致病力都很强,死亡率均为100%。所有毒株对4种禽类的致病性与其临床特征相符。研究结果表明,试验所用的9个分离株除鸽源分离株gxp22外,均为泛嗜性的新城疫强毒株。     

Highlights from a low-level area: infant mortality and social structure in eight East Frisian parishes, 1740–1839

Considerable variations in infant mortality rates have occurred within the low-lying region of northern Germany's East Frisia. Individual parishes can be assigned to three specific groups by registered mortality levels for the period 1740–1839. Differences also existed between parishes containing Geest (heathland), bogs, and marshland reflecting specific geographical and environment factors, as well as the structure of the local economy. In both Geest and bog parishes, the level of infant mortality and its trend over time were not homogeneous. In the two marshy river parishes, only environmental factors were significant; both registered the lowest rates of infant mortality. They had fertile soil, extensive grazing land, an exceptionally high number of large agricultural holdings, and households that were above average in size. By contrast, the highest rates of infant mortality were found in one bog and two Geest parishes, but these communities remained heterogeneous in terms of geographical size and population growth and density.     

The Suicide Mortality Rates between 1997–1998 and 2000–2001 in Nantou County of Taiwan Following the Earthquake of September 21 in 1999

Abstract:  The paper aims to show the different suicide mortality rate between 1997–1998 and 2000–2001 in Nantou County of Taiwan with earthquake on September 21 (often referred to as the "9-21 earthquake") in 1999. In additional, it also identifies the preventive strategies for the high-risk suicide population. The age-standardized mortality rates for suicide in Nantou County were calculated for the years 1997–1998 and 2000–2001. The suicide standardized mortality ratio (SMR for townships in Nantou were calculated by "type of township" as the standard rate). There is a statistically significant difference in male suicide rates for the years prior to the earthquake (1997–1998) when pooled and compared to the suicide rates for the years after the earthquake (2000–2001). The rate for four age groups (under 25, 25–44, 45–64, 65 and above) all increased, yet all but one (the group of age 45–64) was not statistically significant. The male SMR has slightly increased after the 9-21 earthquake. Yet there are no statistical significances in most townships, except in Kaohsiung and Puli after the 9-21 earthquake. The Kaohsiung SMRs were 1.36 (95% CI: 0.54–2.80) before the earthquake (1997–1998) and 2.01 (95% CI: 1.04–3.52) after the earthquake (2000–2001). The SMRs before and after the earthquake in the Puli Township were 1.51 (95% CI: 0.95–2.29) to 1.56 (95% CI: 1.03–2.27). This study suggests that monitoring high-risk population, especially males or 45–64 years of age who experienced the highest statistically significant suicide rate in this study. The study provides support for providing both the psychological restoration program and, to the extent feasible, financial support for the unemployed as useful public health strategies for suicide prevention in Taiwan.     

Patterns of breaks in umbilical cords by different mechanisms*

Investigations of perinatal deaths often result in discrepancies between autopsy findings and witness accounts. The mechanism by which the umbilical cord is severed after delivery is a common quandary. Confirming or refuting the mother's stated method frequently has significant investigative importance; however, a surprising paucity of data currently exists to allow an objective opinion about the likely mechanism. Ninety-nine placentas with umbilical cords were examined. By random selection, each cord was severed by one of the following tools or mechanisms: knives, scissors, traction, or crush. Each break was examined and photographed, and a tissue section from the broken end examined microscopically. Differentiation of mechanism was best done grossly based on specific pattern recognition. Umbilical cords severed by blunt force have distinctly different morphology from those severed by sharp force. Even similar-appearing sharp force transections frequently have mechanism-specific distinctive patterns of injury.     

Maternal mortality in Slovenia: Case report and the method of identifying pregnancy-associated deaths

We report on the case of fatal intracerebral haemorrhage that followed the development of severe preeclampsia/eclampsia with haemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome in a 22-year-old primipara. Peculiarities of the reported case are abrupt onset of preeclampsia/eclampsia during the delivery, fulminant course of the disease, minimal changes in kidneys and signs of pre-existing accelerated arteriosclerosis. Since very few forensic pathologists have sufficient experience with such cases and the differential diagnosis may be difficult, we consider it necessary that in all maternal deaths the post-mortem examination is performed by a team of two forensic pathologists and the case further analysed in collaboration with expert obstetrician.Maternal deaths are rare in developed countries but extremely important, because they represent the “tip of the iceberg” of severe maternal and neonatal morbidity and because they reflect accessibility and quality of prenatal and obstetric care as well as the health status of reproductive-aged women. Unfortunately, they are often misclassified in death certificates which may lead to insufficient engagement in solving underlying problems. In Slovenia, the method of active search for pregnancy-associated deaths is used in order to enable accurate monitoring of maternal mortality and minimise underreporting. The method is based on the manual revision of death certificates and the computer-based linkage of Mortality Database with birth register and foetal deaths register and has proved to be highly efficient.     

Infant Homicide: Victim/Offender Relationship and Causes of Death

The phenomenon of infant homicide (infanticide) has been examined, explained, justified, and treated according to physiological, psychiatric, and psychological correlates. There has been little examination of the social correlates directly pertaining to infant homicide. However, social correlates are often indirectly addressed in the medical and psychiatric literature. This paper tests relationships between social correlates often asserted, but typically not tested, in the medical and psychiatric literature. Using a sample of 380 infant homicides in Texas from 1981 through 1991, a multivariate analysis between victim/offender relationship, cause of death, and victim's age at time of fatal injury, predicts the age at which an infant (34 months) is likely to be fatally injured. The findings support the following hypotheses: (1) as the age of the victim increases, the level of violence used to fatally injure the infant increases; and (2) as the level of relational intimacy decreases, the level of violence used to fatally injure the infant increases.     

Public health measures against neonatal tetanus on the island of Vestmannaeyjar (Iceland) during the 19th century

The article presents a study of neonatal tetanus on the tiny island of Vestmannaeyjar (Iceland) during the 18th and 19th centuries. At an early date, Vestmannaeyjar was known for its high levels of mortality from neonatal tetanus. This appalling mortality is analysed, inter alia, on the basis of parish registers at the individual family level. During the late 18th and early 19th centuries, more than three out of four newborns on the island died during the first 2 weeks of life. At the beginning of the 19th century, Icelandic and Danish authorities had already showed great interest in improving infant survival on Vestmannaeyjar. In 1827 a physician was appointed to the island and by the late 1840s the disease was successfully fought on the island. The achievement on Vestmannaeyjar is a good example of how the sanitary movement was able to bring about important improvements in infant survival long before the breakthrough of the bacteriological revolution.
