Malaria Parasite Density Estimation using Actual and Assumed White Blood Cells Count in Children in Eastern Sudan.

Background: Estimating malaria parasite count is needed for estimating the severity of the disease and during the follow-up.

Objective: This study was conducted to determine the malaria parasite density among children using actual white blood cell (WBC) and the assumed WBC counts (8.0 × 10(9)/l).

Maternal and Umbilical Cord Blood Levels of Zinc and Copper in Active Labor Versus Elective Caesarean Delivery at Khartoum Hospital, Sudan.

A case-control study was conducted in Khartoum Hospital Sudan to determine maternal and umbilical cord blood levels of zinc and copper in active labor versus elective cesarean delivery. Cases were women delivered vaginally and controls were women delivered by elective cesarean (before initiation of labor). Paired maternal and cord zinc and copper were measured using atomic absorption spectrophotometry.

Omega 3 (n-3) fatty acids down-regulate nuclear factor-kappa B (NF-κB) gene and blood cell adhesion molecule expression in patients with homozygous sickle cell disease.

Chronic inflammation and reduced blood levels of omega-3 fatty acids (n-3) are known characteristics of sickle cell disease (SCD).The anti-inflammatory properties of n-3 fatty acids are well recognized. Omega-3 treated (n = 24), hydroxyurea (HU) treated (n = 18), and n-3 untreated (n=21) homozygous SCD patients (HbSS) and healthy (HbAA) controls (n = 25) matched for age (5-16 years), gender and socioeconomic status were studied.

Estimating malaria parasite density among pregnant women at central Sudan using actual and assumed white blood cell count.

Background: Microscopic examination using Giemsa-stained thick blood films remains the reference standard for detection of malaria parasites and it is the only method that is widely and practically available for quantifying malaria parasite density. There are few published data (there was no study during pregnancy) investigating the parasite density (ratio of counted parasites within a given number of microscopic fields against counted white blood cells (WBCs) using actual number of WBCs.

Methods: Parasitaemia was estimated using assumed WBCs (8,000), which was compared to parasitaemia calculated based on each woman's WBCs in 98 pregnant women with uncomplicated Plasmodium falciparum malaria at Medani Maternity Hospital, Central Sudan.

Red blood cell distribution width and iron deficiency anemia among pregnant Sudanese women.

Background: Iron deficiency anemia (IDA) is a major health problem during pregnancy and it has adverse effects on the mother and the newborn. Red cell distribution width (RDW), which is a quantitative measure for red cell size variation (anisocytosis), is a predictor of IDA. Little is known regarding RDW and IDA during pregnancy.
