Published: May 2020

In this study 2-5-10 wt.% thermal power plant ash was added to the granite body replace feldspar to use environmental waste in the ceramic body and to reduce production costs. Loss on inginitions, fired bending strengths, dry strength, fired shrinkages, water absorbtion and colorimeter degrees were measured. Microstructure was determined by scanning electron microscope (SEM), energy dispersive x-ray spectrometer (Edx) and x-ray diffractometer (XRD) measurements. After sintering, it was determined that 2 wt.% fly ash can be used in granite body. In sintered body, according to XRD phase analysis, amount of free quartz and mullite decreased and albite formation was observed. While the fired strength value is 399 kg/cm2 in standard body, it is 315 kg/cm2 in 2 wt.% fly ash added body. In the experiment with 2 wt.% ash additive, according to SEM images, the number and volume of large pores increased while small pores decreased. The ability of pressing of the sample with 10wt.% ash additive was negatively affected due to the excess amount of fine ash and so occure lamination and bloating.

Malaria and the Sickle Gene: Polymorphism Balance in favour of eradication
Authors: Olatunji Phillip O 
Published: May 2020

Evolutionally, the single nucleotide mutation responsible for the sickle haemoglobin gene, (HbS gene) developed from the regions of the world where malaria is holoendemic, leading to the explanation that the mutation is in response to the presence of the malaria parasite. Studies eventually showed that individuals that are heterozygous for the HbS gene are protected from the lethal clinical effects of malaria infection. In other words, malaria confers a survival advantage to carriers of the HbS gene, and this is referred to as balanced polymorphism. On the other hand, malaria infection is associated with significant morbidity and mortality, particularly among children. Unfortunately, lack of success in the effort to eradicate the malaria parasite through the elimination of the Anopheles mosquito or efforts to limit its contact with human being has produced little success, hence the resort to roll back malaria, with the aim of reducing the morbidity and mortality associated with it. Therefore, it is attractive to consider what will happen to the sickle gene if malaria were to be eradicated. That is, the possibility is that the sickle gene may also follow suit since its evolution in the first instance was as a response to malaria., This is the hypothesis being propounded by this article. In that case, rather than shy away from the malaria eradication initiative, it should remain the goal of all malaria programs.
Visual loss from mismanaged ocular injury with foreign body impaction: A Case Report
Authors: Akintoye Ifedayo O. , Adeoti Caroline O. 
Published: May 2020

Ocular injury occurs commonly and it may lead to visual impairment if it is not properly managed. We report the case of a 35-year old man with a retained infected ocular foreign body in his right eye following an injury. The foreign body was not discovered despite consulting non-ophthalmologists at a Maternity Centre and an Optical Shop over a period of ten days. At presentation at the Specialist Hospital, he was unable to see with swelling of the eyelid, red eye and discharge. On examination, the visual acuity in the affected eye was NLP and an infected stick that penetrated the eyeball was discovered in the superonasal aspect of sclera covered by the swollen upper lid. This resulted in endophthalmitis, cataract and blindness of that eye. Ocular injuries must be promptly referred to the ophthalmologist for appropriate care and to prevent complications. The case clearly showed a diagnostic and therapeutic challenge for paramedics who encounter eye injuries outside the tertiary hospital setting. Therefore, this report raises public health concern intended to increase awareness on the management of eye injuries. The incorporation of Primary Eye Health into Primary Health Care along with training and re-training of Community Health Extension Workers, General Practitioners and other rural health workers cannot be overemphasized.

Background: Auto mechanics are exposed to various organic, inorganic and particulate matters as a result of their occupation. Determining the association between environmental pollutant and risk of lung function abnormalities among auto mechanics is important to prevent long-termCem>Objective: To describe lung function abnormalities and their determinants among auto mechanics in Ogbomoso, Nigeria. Methods: One hundred and three auto mechanics were randomly selected from Ogbomoso, Nigeria. Their clinical and demographic data were obtained using a data form. Spirometry was performed using the CONTEC handheld Spirometer. The personal best values of three measurements FEV1, FVC and PEFR were determined. Lung function abnormalities were described according to standardized criteria. Results: The mean (SD) age of the participants was 38.5 (11.9) years. The mean systolic blood pressure, mean diastolic pressure and mean duration of the job as auto mechanics were 128.7 (17.9) mmHg, 81.2 (11.4) mmHg and 20.2 (12.5) years respectively. Restrictive, obstructive and mixed lung function abnormalities were demonstrated among 53%, 10% and 2% respectively. The mean values of FEV1 and FVC reduced significantly with increasing job duration. Conclusion: Lung function abnormalities occurred frequently among auto mechanics in Ogbomoso, Nigeria. There seemed to be a progressive decline in lung functions with age and duration of exposure to organic and inorganic pollutants by auto mechanics. Strict environmental and occupational safety measures may limit the hazards associated with poor air quality and other chemical/physical hazards among auto mechanics in Nigeria.
