Preliminary Geophysical Investigation to Delineate the Groundwater Conductive Zones in the Coastal Region of Akwa Ibom State, Southern Nigeria, around the Gulf of Guinea  [PDF]
George N. Jimmy, Akpan A. Otu, Umoh A. Asuquo
International Journal of Geosciences (IJG) , 2013, DOI: 10.4236/ijg.2013.41011
Abstract:

This paper presents the first work of its kind within the confines of the study area. It unravels the distribution of the layers of conductive sand and their depths of interaction between freshwater from fresh sands and saltwater within the conductive layers in the coastal region of Akwa Ibom State (Nigeria) around the Gulf of Guinea. Vertical electrical sounding (VES) data whose fidelity was achieved by constraining the data by the available nearby logged borehole information during interpretation was the method applied. In the western region of the study area, the ferruginized and saline water layer is found within the depth range of 22 to 75 m deep. In the northern zone, conductive sandy layer is found within 50 to 210 m and in the eastern zone, the saline and ferruginized sandy layer is found within the depth of 88.5 m and above. Generally, the horizontal and vertical cross sections of the subsoil and the flow regime from water table depths have been delineated. With these information, water can be tapped in the area with caution and the flow direction determined can be used as input parameter in detailed contamination study.

Cholecystectomy: Indications at university of Calabar teaching hospital, Calabar, Nigeria
Asuquo M,Umoh M,Nwagbara V,Inyang A
Annals of African Medicine , 2008,
Abstract: Background / objective : The relative rarity of gallbladder disease has been documented in various parts of Africa. Recently the incidence has been reported as rising in some African countries. We undertook this study to evaluate the indications for cholecystectomy in our center and compare with others. Methods : This is a retrospective study of 18 open cholecystectomies in 10years. Results : The ages ranged from 13 and 65 years (mean 39.2years). There were 15 females and 3 males (F: M = ratio 5:1). Calculous cholecystitis 9(50%) in patients, acalculous cholecystitis 8(44.4%) and a patient with carcinoma of the gallbladder were offered cholecystectomy. The commonest stone was mixed multiple stones. Conclusion : The numbers of cholecystectomies attest to the rarity of gallbladder disease in this environment. This may be due to the high fiber and low cholesterol diet predominant in this costal population in southern Nigeria.

International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.35079
Abstract: Background: Penetrating abdominal trauma (PAT) typically involves the violation of the abdominal cavity by a gun-shot wound (GSW) or stab wound Recently several studies have favored a more conservative approach as opposed to mandatory exploratory laparotomy. Methods: Patients admitted in the University of Calabar Teaching Hospital (UCTH), Calabar, with PAT from January 2008 to December 2010 were prospectively studied based on a questionnaire. The total number of patients with PAT was compared with total number of emergencies, traumatic injuries and abdominal trauma seen during the same period. Results: A total of 48 patients presented with abdominal trauma: PAT 29 (60%) and blunt abdominal trauma (BAT) 19 (40%). The ages of the patients (28 male, 1 female) ranged from 3 - 62 years (mean 28.1 years). Gunshot wound (GSW) 11 (38%) patients, stab wound 8 (27.6%) patients and machete cut 4 (13.8%) patients ranked first, second and third respectively as causes of PAT. The commonest organ injury was perforation of the small intestine. Four (13.8%) patients were managed conservatively while 25 (86.2%) patients had laparotomy. The duration of admission ranged from 2 - 19 days (mean 10.5 days). Morbidity [surgical site infection (SSI)] and mortality were recorded in 2 (6.9%) and 3 (10.3%) patients respectively. Conclusion: Key areas that require attention have been highlighted. Revamping the ailing economy and gainful employment for youths are paramount areas that require prompt, dedicated and sustained intervention for reduction in violent crimes.

Abstract:

Background: Road traffic injury remains a major source of blunt abdominal trauma (BAT). Road traffic injury and other forms of trauma have become a major health problem throughout the world especially in low and middle-income countries. In a previous study (2005-2007), abdominal trauma constituted 79 (4.8%) of trauma cases; BAT, 40 (53%) and penetrating abdominal trauma (PAT), 39 (47%). Effective policies on road safety should be developed based on local research and not on adapted models. We present this study to highlight the possible effect of legislation on the ban of the use of motorcycles on blunt abdominal trauma. Methods: Patients that presented to the University of Calabar Teaching Hospital, Calabar with BAT from 2008-2010 were prospectively studied based on a questionnaire following the legislation prohibiting the use of motorcycles. Results: A total of 12,083 patients presented during the study period, trauma patients totaled 4942 (41%), of this, 48 (1%) suffered abdominal trauma: BAT 19 (40%), penetrating abdominal trauma (PAT) 29 (60%). The age range of the patients was from 5 to 48 years (mean 26.6 years) with a M:F = 5.3:1. Road traffic accident (RTA) 17 (90%) [Motorvehicle 7 (37%), motorcycles 10 (53%)] was the commonest cause of trauma. The spleen was the commonest injured organ 14 (74%). Conclusion: Road traffic injury constitutes a public health challenge and the hallmark is prevention. Legislation prohibiting the use of motorcycles may have been responsible for the reduction in BAT.

Dermatofibrosarcoma protuberance: Case Reports
Asuquo M,Umoh M,Ebughe G
Annals of African Medicine , 2007,
Abstract: Background : Dermatofibrosarcoma protuberance (DFSP) is a relatively uncommon soft tissue neoplasm with intermediate to low grade malignancy, rarely metastasizing to regional lymph node or distant site but with proclivity for local recurrence due to inadequate resection. Methods : We evaluated the clinical histories and treatment outcomes of five consecutive patients who had histologic diagnosis of DFSP in the University of Calabar Teaching Hospital between 2000 and 2004. Results :The five cases reported had histologic diagnosis, sought for after excision. The male: female ratio was 2:3 with an age range of 17-35 years (mean, 26.6 years). Two of the lesions involved the neck and the other three sites involved were the anterior chest wall, groin and proximal thigh. Three of the lesions were recurrent. Conclusion : DFSP is an uncommon tumour, painless, cutaneous and multilobulated lesions should arouse the suspicion of this tumour. Early presentation, pre-operative histologic diagnosis and postoperative evaluation of resection margins would enhance the goal of ensuring adequate excision for improved outcome.

John Efiok Nsikan, Victor A. Umoh, Mbaa Bariate
American Journal of Industrial and Business Management (AJIBM) , 2015, DOI: 10.4236/ajibm.2015.58052
Abstract: In Nigeria, the aftermath of the Niger Delta crises had spark off research interest on corporate social responsibility (CSR) and environmental sustainability. However, how telecommunication firms in Nigeria perceive and practice CSR and the link with competitive advantage is rarely investigated. This study examines the extent of relationship between CSR and mobile telecommunication competitive advantage. The survey design was adopted, making use of random sampling to select 200 participants from staff of MTN. Structured questionnaire was employed to collect relevant primary data and analysis was carried out through regression analysis and Chi-square technique. Results showed that except staff welfare, significant relationship existed between environmental awareness, community wellbeing and competitive advantage. To further enhance competitiveness, the firm’s social responsibility to its workforce should be improved upon by introducing flexible working hours, facilitating work/life balance, ensuring prompt promotion, and considering internal advancement as a strategic option.

Open Journal of Marine Science (OJMS) , 2018, DOI: 10.4236/ojms.2018.84025
Abstract:
Pipelines are system of pipes designed to transport liquids, gases or solid/ liquid mixtures over long distances. Some are used for domestic, household and sewage purposes. Others are buried underground or submerged in water for transportation of natural oil and gas (O & G) products. In this work, the specimens had to be kept in a workable state and steps were taken to prepare each specimen: all cuts and sheared edges were ground out to prevent them from becoming sites for preferential attack. The finishing of the specimen surface with grit abrasive paper (sand paper) and rinsing of the specimens in distilled water were done. Then degreasing of specimen in acetone and air-dried were carried out. Upon drying, the specimens were immediately weighed to obtain their initial weights. Twelve specimens were used for the test as follows: 6 Aluminum (Al); and 6 mild steel (MS) samples. With a 2 M concentration of Vernomia Amydalina (VA) extract solution, the MS and Al samples were immersed in different plastic containers containing 400 ml of seawater with pH value of 7.25 with no (0%) inhibitor added to it. A 5% (400 ml) of the VA solution was poured into the measuring cylinder for each sample-Al and MS. The specimens were suspended by the strings and completely immersed in the different percentage test media. The same procedure was carried out for each of the different percentages, 10%, 15%, 20%, and 25% and a total of 12 solutions were set up. The experimental procedure used was that seawater of 7.25 pH was obtained from Abonnema water front of Rivers State. At the end of every week (168 hours), the specimens were removed from the corrosive media. Observation and recording of appearance of the specimen noting sites were done. Cleanings of specimen with white handkerchief or tissue paper were carried out and washing of specimen with distilled water, scrubbing of specimen with a soft brush and dipping the specimen into acetone after washing, it was removed to air-dry and weighed. It is observed that optimum inhibition of coupons was obtained between 15% - 25% of VA solution during the first four weeks of testing. At the fifth week the inhibitor was gradually losing its effectiveness. This means that more inhibitor need be added at regular intervals to sustain the effectiveness of the inhibitor.

Abstract: Diabetic foot disease is a major medical, social, and economic problem. This retrospective study assessed the profile of diabetes mellitus patients with foot ulcers in the University of Calabar Teaching Hospital (UCTH), Nigeria. Admission records of all patients admitted unto the medical wards of UCTH over a 5 year period were analysed. The records of diabetic patients were retrieved. Data on patient characteristics and possible risk factors for diabetes mellitus foot ulcers was extracted. Of the 3,882 patients admitted, 297 (7%) were on account of complications of diabetes mellitus. Foot ulcers accounted for 63 (21.2%) of all diabetic admissions. The elderly constituted the majority of patients admitted with foot ulcers. The average duration of stay of diabetics with foot ulcers was 38.5 days. Diabetics admitted for other conditions had average duration of admission of 15.8 days. Staphylococcus aureus was the commonest organism isolated from swabs of foot ulcers. Most of the organisms identified from ulcer swab cultures were sensitive to quinolones and resistant to penicillins. These diabetic foot ulcers were significantly associated with peripheral sensory neuropathy, peripheral vascular disease, intermittent claudication, and walking barefoot. An effective diabetes foot programme is required to address these risk factors and reverse the current trend. 1. Introduction Diabetes mellitus (DM) remains a very common endocrine disorder with major public health consequences arising from severe damage to numerous end organs [1]. DM affects all populations worldwide and the prevalence of this disease is increasing at a very alarming rate [2, 3]. The International Diabetes Federation (IDF) currently estimates that about 366 million persons in the world have DM, with projections that this will increase to 552 million by 2030 [4]. The IDF estimated that there were 12.1 million people living with diabetes in Africa in 2010 with a projected rise to 23.9 million by 2030 [5]. In Nigeria, DM remains the most common chronic endocrine-metabolic disorder similar to what is found in other parts of the world [6, 7]. As the incidence of DM is rising dramatically worldwide, so is the incidence of diabetic foot disease [8]. Diabetic foot disease is a major medical, social, and economic problem, that is, seen in every continent and constitutes a major burden to the patient and the health care system [8]. The lifetime risk of a person with diabetes developing diabetes mellitus foot ulcers (DMFU) is reported to be as high as 25% [9]. In Nigeria, around 10% of people with
Farmers Credit Reserve and the Success of Microfinance Institutions in Cross River State, Nigeria
Emmanuel O. Eyo,Innocent A. Asuquo
Agricultural Journal , 2013, DOI: 10.3923/aj.2011.74.81
Abstract: This study assesses credit reserve of crop farmers in Cross River state and the determinants of its use in obtaining loans from the microfinance institutions. The study reveals that the crop farmers use only about 9.0% of their reserves on the average in obtaining loans. However, farm size and education are the most important determinants of the extent that the crop farmers allocate more credit to loans. For the microfinance institutions to improve outreach and performance, farm size and education enhancing programs must be introduced to compel the farmers to allocate more credit in reserve to loan.
