Vitamin D and Its Role During Pregnancy in Attaining Optimal Health of Mother and Fetus
Carol L. Wagner,Sarah N. Taylor,Adekunle Dawodu,Donna D. Johnson,Bruce W. Hollis
Nutrients , 2012, DOI: 10.3390/nu4030208
Abstract: Despite its discovery a hundred years ago, vitamin D has emerged as one of the most controversial nutrients and prohormones of the 21st century. Its role in calcium metabolism and bone health is undisputed but its role in immune function and long-term health is debated. There are clear indicators from in vitro and animal in vivo studies that point to vitamin D’s indisputable role in both innate and adaptive immunity; however, the translation of these findings to clinical practice, including the care of the pregnant woman, has not occurred. Until recently, there has been a paucity of data from randomized controlled trials to establish clear cut beneficial effects of vitamin D supplementation during pregnancy. An overview of vitamin metabolism, states of deficiency, and the results of recent clinical trials conducted in the U.S. are presented with an emphasis on what is known and what questions remain to be answered.
Retropharyngeal emphysema: An unusual aetiology—A case report and literature review  [PDF]
Daniel Adekunle, Onakoya Paul Adekunle
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.23053
Abstract:

Introduction: Retropharyngeal emphysema is a potentially life threatening condition which may require urgent diagnosis and intervention. It has been documented to occur following trauma to the aerodigestive tract and is usually accompanied by subcutaneous emphysema of the cervical region. This condition may be complicated by mediastinal emphysema and pneumomediastinum. Foreign body ingestion is quite common in little children and in this environment; a cultural practice is for mothers or other caregivers to attempt to remove these foreign bodies by forcing their finger(s) down the oropharynx and Hypopharynx of these young children. This usually results in injuries to these anatomical sites. Retropharyngeal emphysema complicating this practice is rarely reported. Case presentation: We present the case of a 4-year-old Nigerian boy who presented with stridor and severe dyspnoea following repeated attempts at removal of a purportedly ingested foreign body by his mother. Examination revealed oedema of the soft palate with small multiple bleeding shallow lacerations of the oropharyngeal walls. Oxygen therapy was commenced and preparations for urgent upper airway intervention made. Soft tissue neck X-ray revealed retropharyngeal and subcutaneous emphysema with upper airway compromise. Conservative treatment with high dose steroids and antibiotics led to a gradual resolution of the condition. Conclusion: This is a rarely reported complication of this relatively common socio-cultural “foreign body removal method”. Public awareness is required to stop this potentially life threatening practice.

An Assessment of Ionospheric Error Mitigation Techniques for GNSS Estimation in the Low Equatorial African Region  [PDF]

Positioning (POS) , 2014, DOI: 10.4236/pos.2014.51004
Abstract:

Single frequency GNSS receivers are the most widely used tools for tracking, navigation and geo-referencing around the world. It is estimated that over 75% of all GNSS receivers used globally are single frequency receivers and users experience positioning error due to the ionosphere. To enable GNSS Single Frequency Precise Point Positioning (SFPPP), accurate a-prior information about the ionosphere is needed. The variation of the ionosphere is larger around the magnetic equator and therefore depends on latitude. It will be expected that SFPPP works better on latitude further from the magnetic equator. This present study aims to investigate the accuracy of some ionospheric error mitigation approaches used in single frequency precise point positioning (SFPPP) at several GNSS station in the new Nigerian GNSS Network (NIGNet) and two IGS sites in the low equatorial African region. This study covers two epochs of observation. The first consists of observation from three consecutive days (GPS week 1638; days 0, 1 and 2) that belongs to a period of low solar activities. The second epoch consists of observation from three consecutive days (GPS week 1647; days 2, 3 and 4) that belongs to a high solar activity and intense geomagnetic conditions. The estimated position for the GNSS stations from dual frequency measurement and their known ITRF solutions were used as a benchmark to assess the accuracy of SFPPP under four conditions i.e., SFPPP without ionospheric correction, SFPPP using final GIM models from the Centre for Orbit Determination in Europe( CODE), SFPPP with Klobuchar model, and SFPPP with a computed (local) model at each station. All computation was done using Leica Geo-office software. The result of the study clearly demonstrates the significance of removing or correcting for the effect of the ionosphere, which can result in up to 7 m displacement.

The role of punch biopsy in the management of carcinoma of the cervix in a low resource centre  [PDF]

Open Journal of Clinical Diagnostics (OJCD) , 2013, DOI: 10.4236/ojcd.2013.34031
Abstract: Background: Carcinoma of the cervix is the commonest malignant tumor of the female genital tract in Northern Nigeria and the leading cause of cancer-related death in women in developing countries. The predicament is further worsened by poor uptake of cytological screening programs, which are either not available or where available are underutilized due  to lack of widespread awareness and the cost as    an average Nigerian earns less than a dollar per day. In addition to the above constrains, majority of these patients also presents late to the hospital for intervention. Objective: To emphasize the significance of punch biopsy and clinical staging of advanced carcinoma of the cervix and see how we can shift from our traditional, Examination under Anesthesia (EUA) to Clinical staging and punch biopsy for advanced carcinoma of the cervix. Methodology: Review of existing literature and experience from our own center. Results: The punch biopsy has 88.8% positive predictive value in making a diagnosis of cancer of the cervix. Late presentation was as high as 81.7 percent for carcinoma of the cervix in our centre. The patients present late for care; majority actually presents in stages III & IV when little or nothing can be done for them. Conclusion: In view of these predicaments that face a gynecological oncologist practicing in low resources settings like ours, there is a need to consider the role of punch biopsy, clinical staging and radio-logical assessment for making a diagnosis, especially among those women who cannot afford EUA or are having renal complication that makes EUA unachievable.

Open Journal of Polymer Chemistry (OJPChem) , 2014, DOI: 10.4236/ojpchem.2014.44011
Abstract: Triglyceride oil of plant seed cannot be used on its own without further modification. The fatty acids must be suitably functionalized in order to add polymerisable functionalities which will help in the curing process. The purpose of these modifications is to reach a higher level of molecular weight and cross-link density, and also to incorporate chemical functionalities known to impart stiffness in a polymer network. The modification can go through various path ways which were described in this study.
Deviant Realization of Foreign Vowels in the Speech-Form of Yoruba-English Nigerian Bilinguals  [PDF]
Ojo George Adekunle
Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.45062
Abstract: This paper discusses deviant realization of borrowed phonemes from English into Yorùbá. It is not gainsaying that when a foreign phoneme enters into the syllable structure of English it changes its tongue position both horizontally and vertically. The reason for this change is not far-fetched. Since the majority of the foreign phonemes are absent in native languages, they tend to be substituted with the closest phonemes in the recipient language. This paper has been able to account for the various substitutions of foreign vowels that occur in the speech-form of Nigerians who code-mix English with Yorùbá in their daily conversations. This has been done through the analysis of corpus of data collected from the existing foreign words as spoken by Yoruba-English bilinguals. The result of analysis shows that two or more foreign phonemes become one native phoneme that is entirely different from the input when processed in the recipient language.
Surface Treatments of Natural Fibres—A Review: Part 1  [PDF]
Kayode Feyisetan Adekunle
Open Journal of Polymer Chemistry (OJPChem) , 2015, DOI: 10.4236/ojpchem.2015.53005
Abstract: This review is based on the surface treatment of natural fibres which can be used in technical applications. Natural fibres on their own have some draw backs regarding moisture uptake, quality variations, low thermal stability, and poor wettability. Insufficient adhesion between polymer matrix and fibre leads in time to debonding. Overcoming the weaknesses of these natural fibres gave the motivation for this study where physical and chemical methods of modification were considered. Physical methods such as electric discharge and mercerization were reported as well as the chemical methods such as graft copolymerization and treatment with isocyanates, and the results due to these modifications were discussed. This study reveals that natural fibres are good candidates for reinforcement but they have to be suitably treated to improve their properties if they are to be used in technical applications. The various fibre surface treatments actually improve the interfacial adhesion between the fibre surface and the matrix, thereby giving good mechanical properties to the resulted polymer composites.

Kayode F. Adekunle
Open Journal of Polymer Chemistry (OJPChem) , 2015, DOI: 10.4236/ojpchem.2015.53004
Abstract: The reviewed work addressed the shift in focus from conventional polymers to bio-based and renewable polymers. The environmental attributes of the renewable polymers make them preferred choice of matrix. The properties of the matrices from renewable origin could compete in high end applications. The composition of the fatty acids in plant seed oil was discussed and the determination of the level of unsaturation used the iodine value. This review also extensively discussed the values of various fatty acid components present in the oils. Areas of application of the thermosetting polymers obtained from plant seed oils were also discussed.

Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.47023
Abstract: This study aims at examining the factors that influence inadequate water supply in Owah-Abbi. The research was conducted by applying the survey research design and data relevant to the topic of study were generated via direct field measurement and administration of questionnaire. Findings include: major sources of water in Owah Abbi Community including Borehole (57.33%), hand dug well (21.33%) and River/Stream water (12%), and those who depend on rain water are 9.33%. It was also revealed that in Owah-Abbi Community water is provided by Government (42.66%); Community (20.67%); Individual efforts (10.67%) and other bodies (26%). Similarly, causes of the water shortage in Owah-Abbi Community included corruption (37.33%); unfavourable Government policies (25.33%); while 17.33% blamed it on the theft and vandalization of Owah-Abbi water supply facilities. Others were the poor management culture of the facilities (8.67%), Erratic Power supply in the community (6.67%), Faulty Hydraulic equipment (2.67%) and carelessness (2%). The study recommended that the government should provide water for the people of Owah-Abbi as a matter of urgency; protection of the existing water infrastructures was also required; the people of Owah-Abbi should be advised on the need to purify water; enlightenment programs should be carried out in the area.
Efficacy of a clinical stroke score in monitoring complications in acute ischaemic stroke patients could be used as an independent prognostic factor
CO Dawodu, RT Bamisile
Annals of African Medicine , 2011,
Abstract: Background: Presence of medical complications in stroke patients has been established. The efficacy of a stroke score in intensive monitoring of these complications in acute ischaemic stroke patients has not been studied. Methods: Eighty-seven patients with acute ischaemic stroke were assessed with National Institute of Health Stroke Scale (NIHSS) by the examiner within days of admission; (1, 7, 30, and 90 days). Onset and types of complications were documented within the duration of the study period, using a questionnaire and laboratory investigations. Results: Fifty-nine [67.8%] patients in the study population had complications, with mean initial NIHSS score 17.1 ± 7.9; mortality was 39%, and 27.8% of survivors had good recovery. In patients without complications, the mean initial NIHSS score was 11.4 ± 6.0; mortality was not observed, and 50% of survivors had good recovery. Conclusion: All patients without complications survived. High NIHSS scores, (with minimal changes below baseline) were related to high mortality and morbidity in the complications group.
