Eclampsia: is there a seasonal variation in incidence?

Abstract

To clarify whether seasonal variation of temperature and humidity has any effect on the incidence of eclampsia. Eclampsia is the second major cause of maternal mortality in Pakistan. Data was collected monthwise for the year 1996 from 4 large Govt. teaching hospitals of 4 provincial metropolis of Pakistan. Each province has diverse climate with considerable variation of air temperature and humidity. There were 395 cases of eclampsia amongst 18,483 deliveries in 1996, giving an incidence of 2.14%. In Karachi (Sindh Province) with mild hot and humid climate and mild winter months, there was increase in eclampsia cases from April-July and in September. Otherwise the incidence remained stable. In Rawalpindi (Punjab Province) with moderately hot summer and cold winter, it was highest in hot season from May to September but was stable in winter. In Peshawar (N.W.F.P) and Quetta (Baluchistan Province) with more severe cold and dry winter the incidence peaked in winter and summer months both. The pattern of eclampsia cases showed variations in extremes of temperature but it was stable in mild weather. However, the statistical analysis revealed non-significant relationship of incidence of eclampsia with temperature when analysed by line...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
