Etiological and Evolutionary Profile of the Child’s Pericarditis in Tropical Environments

Pericarditis is an inflammation of the lining surrounding the heart (the pericardial sac). Pericardial effusion is a collection of fluid in the pericardial sac. This fluid may be produced by inflammation. The cause of pericarditis in most individuals is unknown but is likely due to viral infection. This study was to describe the etiological and evolutionary aspects of fluid pericarditis in pediatric cardiology at Institute of Cardiology of Abidjan (ICA). 

The authors conducted a retrospective study of 42 cases of fluid pericarditis diagnosed among 202 children hospitalized over a five-year period (1st January 2009 to 31st December 2014). All patients with pericardial effusion were included in the study. The prevalence was estimated at 20.8% of hospitalizations, sex ratio was 1.1 with a female predominance (52%) and the mean age at 9.2 years old (11 days old to 15 years old).

The results indicated that dyspnea (64%), cardiomegaly (24%), fever (10%) and chest pain (48%) were dominated by the discovery. The most frequently seen radiological abnormality was cardiomegaly (100%). The mean of the cardiothoracic index (I.C.T) was 0.71 with extremes ranging from 0.59 to 0.87. The etiological investigation made it possible to link fluid pericarditis to a cause in all the patients and the etiologic varieties identified were: tuberculosis 22 cases, 52%, rheumatic pericarditis 6 cases (14.3%), chronic parietal endocarditis 5 cases (11.9%), bacterial pericarditis with trivial germ 3 cases (7.1% 3 cases (7.1%), post-surgery syndrome 2 cases (4.8%), umbilical post-catheterization 1 case (2.4%). HIV serology was positive in 11.9% of cases. The progression was favorable in 55% of the cases with 10% of deaths. 

In conclusion, fluid pericarditis in children is a severe condition that is clearly on the rise today, especially in immunocompromised patients. Optimal management of fluid pericarditis in children is the best guarantee to avoid short-term tamponade and in the medium term constriction.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

The Influence of Heated Soil in Crop of “Tamaris” Tomato Plants on the Biological Activity of the Rhizosphere Soil

Tomato is a plant with high heat requirements and sensitive to cold weather and frost. The optimum temperature for the growth of tomato plants is between 21˚C and 27˚C during the day and between 17˚C and 21˚C at night. The soil temperature is also very important for plant growth. The optimum soil temperature for tomato cultivation should be within the range 15˚C - 18˚C. Besides, the proper development of the root system depends on the optimal temperature of the soil. A temperature below 14˚C reduces and inhibits the growth of the root system and encourages the development of fungal and bacterial diseases. In this study, the authors aimed to evaluate the effect of heated soil on the population of bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. The experiment was carried out in 12 treatments and in 3 replications (one slab was one replication). The soils were tested in two different types of containers: cylinders...

Effect of Proline Pretreatment on Grapevine Shoot-Tip Response to a Droplet-Vitrification Protocol

Proline is an α-amino acid that is used in the biosynthesis of proteins. Some studies have shown that proline has been accumulated in plants in response to biotic and abiotic stresses. Exogenous proline has thus been used for improving some plant cryopreservation protocols. Further enhancement of cryopreservation efficiency for  in vitro  grapevines could be expected if stresses linked to cryopreservation procedures could be reduced. In this study, the authors studied the possible beneficial effect of proline in grapevine cryopreservation. Single-node explants from  in vitro  grown grapevine plantlets ( Vitis vinifera  L. cv Portan) were cultured on shooting media (half-strength MS + 1 μM BAP) containing no proline (control) or 50, 500, or 2000 μM filter-sterilized L-proline. Shoot tips excised from these microshoots were subjected to a PVS2-based droplet-vitrification procedure. Control and rewarmed explants were grown on a recovery medium containing ...
