Nicotinic Receptors in the Brainstem Ascending Arousal System in SIDS With Analysis of Pre-natal Exposures to Maternal Smoking and Alcohol in High-Risk Populations of the Safe Passage Study.

Pre-natal exposures to nicotine and alcohol are known risk factors for sudden infant death syndrome (SIDS), the leading cause of post-neonatal infant mortality. Here, we present data on nicotinic receptor binding, as determined by I-epibatidine receptor autoradiography, in the brainstems of infants dying of SIDS and of other known causes of death collected from the Safe Passage Study, a prospective, multicenter study with clinical sites in Cape Town, South Africa and 5 United States sites, including 2 American Indian Reservations. We examined 15 pons and medulla regions related to cardiovascular control and arousal in infants dying of SIDS ( = 12) and infants dying from known causes ( = 20, 10 pre-discharge from time of birth, 10 post-discharge).

COVID-19 Pandemic: Is Africa Different?

COVID-19 has now spread to all the continents of the world with the possible exception of Antarctica. However, Africa appears different when compared with all the other continents. The absence of exponential growth and the low mortality rates contrary to that experienced in other continents, and contrary to the projections for Africa by various agencies, including the World Health Organization (WHO) has been a puzzle to many.

Concurrent prenatal drinking and smoking increases risk for SIDS: Safe Passage Study report.

Background: Sudden infant death syndrome (SIDS) is the leading cause of postneonatal mortality. Although the rate has plateaued, any unexpected death of an infant is a family tragedy thus finding causes and contributors to risk remains a major public health concern. The primary objective of this investigation was to determine patterns of drinking and smoking during pregnancy that increase risk of SIDS.

A retrospective review of fatal electrocution cases at Tygerberg Forensic Pathology Services, Cape Town, South Africa, over the 5-year period 1 January 2008 - 31 December 2012.

Background: Electrocution as a cause of death has been discussed extensively in the international literature. However, research on this topic in South Africa (SA) is scarce.

Objectives: To address the need for further research in this field and emphasise the necessity for preventive measures by determining the demographic and pathological profile of fatal electrocution cases seen in the Tygerberg Forensic Pathology Services, Western Cape Province, SA.

The Institution of a Standardized Investigation Protocol for Sudden Infant Death in the Eastern Metropole, Cape Town, South Africa

The rate for the sudden infant death syndrome (SIDS) in Cape Town, South Africa, is estimated to be among the highest in the world (3.41/1000 live births). In several of these areas, including those of extreme poverty, only sporadic, nonstandardized infant autopsy, and death scene investigation (DSI) occurred.

Serotonin Receptors in the Medulla Oblongata of the Human Fetus and Infant: The Analytic Approach of the International Safe Passage Study.

The Safe Passage Study is an international, prospective study of approximately 12 000 pregnancies to determine the effects of prenatal alcohol exposure (PAE) upon stillbirth and the sudden infant death syndrome (SIDS). A key objective of the study is to elucidate adverse effects of PAE upon binding to serotonin (5-HT) 1A receptors in brainstem homeostatic networks postulated to be abnormal in unexplained stillbirth and/or SIDS. We undertook a feasibility assessment of 5-HT1A receptor binding using autoradiography in the medulla oblongata (6 nuclei in 27 cases).

A 10-year review of fatal community assault cases at a regional forensic pathology facility in Cape Town, South Africa.

Background: An increase in autopsied community assault (CA) fatalities was observed at the Tygerberg Forensic Pathology Services (FPS), Cape Town, South Africa (SA). There is a paucity of information on the incidence and prevalence of these cases in SA.

Objectives: To determine the patterns and trends of injuries sustained in so-called CA fatalities.

Renal failure in HIV-positive patients-a South African experience.

Background: Kidney disease is a major complication of HIV infection, with both acute kidney injury (AKI) and chronic kidney disease (CKD) contributing to morbidity and mortality. Incidence of AKI was reported as 5.9 per 100 patient years in ambulatory patients and ∼18% in hospitalized HIV-infected patients, an almost 3-fold higher risk compared with HIV uninfected patients in developed countries.

Living kidney donor transplants over a 16-year period in South Africa: a single center experience.

Background: Kidney transplantation is the treatment of choice for end-stage renal disease (ESRD). The number of patients on the waiting list is increasing due to an imbalance between organ supply and demand. This has led to an increase in the number of living donor transplants in most parts of the world.

Progressive primary pulmonary tuberculosis presenting as the sudden unexpected death in infancy: a case report.

The classification of an unexpected infant death as the sudden infant death syndrome (SIDS) depends upon a complete autopsy and death scene investigation to exclude known causes of death. Here we report the death of a 4-month-old infant in a tuberculosis endemic area that presented as a sudden unexpected death in infancy (SUDI) with no apparent explanation based on the death scene characteristics. The autopsy, however, revealed progressive primary pulmonary tuberculosis with intrathoracicadenopathy, compression of the tracheobronchial tree and miliary lesions in the liver.

The medico-legal investigation of sudden, unexpected and/or unexplained infant deaths in South Africa: where are we--and where are we going?

Sudden Infant Death Syndrome (SIDS) has been reported to be the leading cause of death in infants under 1 year of age in many countries. Unfortunately, a paucity of published research data exists in South Africa, with regard to the incidence of and investigation into the circumstances surrounding Sudden Unexplained Deaths in Infants (SUDI) and/or SIDS. Currently, even though most academic centers conform to a protocol consistent with internationally accepted standards, there exists no nationally accepted infant death investigation protocol in South Africa.

Hepatic hemangioendothelioma presenting as sudden unexpected death in infancy: a case report.

The classification of an unexpected infant death as sudden infant death syndrome (SIDS) depends upon a complete autopsy, death scene investigation, and review of medical history to exclude known causes of death. Death from occult neoplastic disease in infancy is extremely rare but is within the broad differential diagnosis of SIDS. We report the sudden and unexpected death of a 1-month-old infant from a hepatic (infantile) hemangioendothelioma.

Urinary screening abnormalities in antiretroviral-naive HIV-infected outpatients and implications for management--a single-center study in South Africa.

Few urinary screening studies have been performed to determine the incidence of urinary abnormalities in antiretroviral therapy-naive, HIV-infected outpatients. From published data, the incidence appears to be high, particularly when compared with populations outside sub-Saharan Africa. In South Africa, urinary screening in antiretroviral therapy clinics is not routinely practiced.

A practical classification schema incorporating consideration of possible asphyxia in cases of sudden unexpected infant death.

Although the rate of the sudden infant death syndrome (SIDS) has decreased over the last two decades, medical examiners and coroners are increasingly unwilling to use the SIDS diagnosis, particularly when there is an unsafe sleeping environment that might pose a risk for asphyxia. In order to reliably classify the infant deaths studied in a research setting in the mixed ancestory population in Cape Town, South Africa, we tested a classification system devised by us that incorporates the uncertainty of asphyxial risks at an infant death scene. We classified sudden infant deaths as: A) SIDS (where only a trivial potential for an overt asphyxial event existed); B) Unclassified-Possibly Asphyxial-Related (when any potential for an asphyxial death existed); C) Unclassified-Non-Asphyxial-Related (e.

Infection and glomerulonephritis.

Glomerular injury, occurring either as primary glomerular disease or as part of a systemic disease process, is usually a result of immune-mediated mechanisms. The morphologic reaction pattern has a diverse spectrum of appearance, ranging from normal by light microscopy in minimal change disease to crescentic forms of glomerulonephritis, with conspicuous disruption of the normal glomerular morphology. The mechanisms of glomerular immune deposit formation include trapping of circulating antigen-antibody complexes and the in situ formation of immune complexes within the glomerulus.

Causes and predictors of death in South Africans with systemic lupus erythematosus.

Objectives: Little is known about the long-term outcome and mortality patterns in systemic lupus erythematosus (SLE) in sub-Saharan Africa. We undertook a retrospective study of SLE in mainly black, unemployed patients, seen at a tertiary institution in Soweto, South Africa, to determine the causes and predictors of death.

Methods: Demographic, clinical and laboratory data and outcome were extracted from the case records of patients attending the Lupus Clinic at Chris Hani Baragwanath Hospital.
