Iatrogenic burns injury complicating neonatal resuscitation
T A Ogunlesi, S B Oseni, J A Okeniyi, J A Owa
West African Journal of Medicine , 2006,
Abstract: A case of iatrogenic thermal injury in a newborn infant during resuscitation for perinatal asphyxia at a secondary health facility is described. The injury, with surface area coverage of about 4%, involved the lower limbs. This report highlights the poor newborn resuscitation skills of traditional medical practice. Un cas d'une blessure therminale iatrogénique chez un bébé nouveau né au cours d'une réanimation pour l'asphyxie périnatale dans une centre sanitaire est l'objet de cette étude. La blessure dans les membres inférieurs a une surface d'environ 4%. Cette communication souligne la mauvaise méthode traditionnelle de la réanimation chez des nouveau nés.
Factors Associated with Placenta Weight and Placental Weight/Birthweight Percent (Placental Ratio) Among Mothers in Ilesa, Southwestern Nigeria

International Journal of Tropical Medicine , 2012,
Abstract: The aim of the study is to determine birth weights, placental weight and Placental to Birth Weight Percentages (PBWP) in consecutive, live singleton term births and study their relationship with some maternal and foetal factors. Subjects were mothers of consecutive, live, singleton, full term neonates delivered at the Wesley Guild Hospital, Ilesa, Nigeria between January and August 2002. Each placenta was weighed and the placental to birth weight percent was calculated. The socio-economic classes of the parents, nutritional status of the mothers using the Body Mass Index (BMI), age and parity of the mothers, gestational ages of the babies derived from the mothers LMP and/ or Dubowitz score, as well as the weight and ponderal index of babies were all recorded. Foetal malnutrition/wasting was diagnosed using Clinical Assessment of Foetal Nutritional Status (CANS) and the score (CANSCORE) as adapted by Metcoff. The mean placental weights were examined in relation to maternal age, BMI, parity and socioeconomic class and the babies ponderal index, birth weight, length, occipitofrontal circumference and presence or absence of Foetal Malnutrition (FM). A total of 473 mothers and their babies were assessed. These babies consisted of 246 [52%] males and 227 [48%] females giving a male: female ratio of 1.08:1. The placental to birth weight percent (placental ratio) ranged between 17.8 and 18.7% with a mean of 18.4%. The mean placental weight for males was significantly higher than for females 577.44 (SD130.58)g versus 551.94 (SD108.62)g, t= 2.3, p< 0.025.The mean placental to birth weight percent for males and females were 18.2 and 18.5%, respectively. Younger aged mothers, low BMI (< 18.5kg m 2), low socioeconomic class (III-V) and lower parity (I and II) mothers had lower placental. Female sex, low birthweight babies, presence of foetal malnutrition (FM) and low ponderal index (< 2.32g cm 3) babies had significantly lower placental weight than otherwise (p< 0.05 at least). The estimates of regression coefficients distribution for the variables also show that high Placental to Birth Weight Percentage (PBWP) has significant independent effects on the presence of low birth weight at term, low ponderal index and presence of severe birth asphyxia. Placental weight and placental to birth weight percent are therefore useful in the identification of babies at risk of foetal malnutrition. Low placental weight and foetal malnutrition may have similar aetiopathogenesis. Further study of the placentas may therefore give information which may be useful in preventing these complications.
Abundance of earthworms in Nigerian ecological zones: implications for sustaining fertilizer-free soil fertility

African Zoology , 2011,
Abstract: The abundance of earthworms in the ecological zones in Nigeria has been determined and the possibility of earthworm functions replacing both mechanized land preparation and organic fertilizers discussed. The most abundant earthworms, comprising 62 % of the population, were the advantageous solid-wormcast makers. Mixed Leguminous Wooded Savanna had the highest earthworm density (1.50 million worms/ha), while Wooded Savanna had the lowest (0.23 million worms/ha). Coastal Forest and Mangrove (0.51 t/ha) had the highest earthworm biomass and Afziela Savanna/Semi-Deciduous Forest (0.03 t/ha) had the least. A new soil impact index (SIINDEX) is introduced, which simultaneously incorporates both earthwormbiomass and density. The highest SIINDEX was from Mixed Leguminous Wooded Savanna (0.72) and the lowest from Afziella Savanna/Semi-Deciduous Forest (0.11). Forests with SIINDEX less than 0.2 should be regarded as endangered, because their earthworm functions are too low to accomplish significant leaf-litter breakdown and recycling. We suggest that if the illegal annual bush burning is prevented, the soil surface will be naturally mulched,earthworms protected, and by their function in the soil, the need for soil mechanization and fertilization could be replaced by earthworms to produce natural foods

International Journal of Mathematics and Mathematical Sciences , 1992, DOI: 10.1155/s0161171292000796
Abstract: A certain class B(n, ±, 2) of Bazilevi functions of order 2 in the unit disk is introduced. The object of the present paper is to derive some properties of functions belonging to the class B(n, ±, 2). Our result for the class B(n, ±, 2) is the improvement of the theorem by N. E. Cho ([1]).

Abstract: The object ofthe present paper is to give some generalizations of results for certain analytic functions which were proved by Saitoh (Math. Japon. 35 (1990), 1073-1076). Our results contain some corollaries as the special cases.
