The assessment of the impact of road infrastructure in the developing countries using the Namibian case scenario was done based on the contemporary challenges of road use. This study employed a qualitative technique using a sample size of thirty (30) selected by the simple random sampling technique. The use of charts, tables and frequencies were done to explain certain trends in the study. A well-structured, valid and reliable questionnaire instrument was designed for the study based on the following research questions;what are the impacts of road transport on the Namibian environment and what are the possible measures that may be used to reduce environmental impact of road transport on the Namibian environment? Twenty five respondents (83%) agreed that road transfer has drastically improved development and 26 (87%) respondents also accepted that it can improve Namibian economy. Similarly, it has also improved communication and technology greatly according to 27 (90%) respondents. To add more credence to the impact of road transport on the economy, all the 30 (100%) of the respondents agreed that road transport aids mobility within Namibia while 27 (90%) respondents supported the opinion that road transport aids in job search, 3 (10%) disagreed. The result shows that car owners service are potential threats which can affect pollution levels as was supported by 97% to cause environmental pollution as well as 100% when combined with energy consumption. Similarly, all the respondents indicated the potential of increased accident rate from poor road safety. Felling of trees poses great danger (97% response) due to the degradation of the environment. Most respondents (77% and 83%) agreed that road transport can lead to land encroachment and loss of aesthetic and farming. This research has shown that eventually death rate may increase from mere ill-health to from the degraded ecosystem, 24 respondents (80%). So many policies to protect the environment but the practical me

引用

International Journal of Clinical Medicine 2011年第2期2卷 93-96页

作者： Asuquo Maurice Otei Otei nwagbara victor Ebughe Godwin Omotoso Joshua 不详

Background: Basal cell carcinoma (BCC) is the commonest malignancy among Caucasians in Europe, North America, and Australia. This study attempted to identify the prevalence, risk factors, and outcome of management of this problem in our region. Methods: All the patients with histologic diagnosis of BCC presenting to the University of Calabar Teaching Hospital, Calabar during the study period January 2000 to December 2009 were evaluated. Results: One hundred and fifty two patients (136 blacks, 16 albinos) were afflicted with skin malignancy, squamous cell carcinoma and BCC totaled 70 [SCC – 62, BCC – 8], and malignant melanoma (MM) – 16. Of the 8 patients, (3 males and 5 females, mean age 43 years, range 21-65 years) observed with BCC lesions, 2 (25%) were darkly pigmented and 6 (75%) were albinos. Most of the albinos who presented 3 decades before the darkly pigmented ranged in age from 21-60 years (mean 35.7 years). The lesions afflicted the head and neck region, 9 (82%), while 2 (18%) were observed on the upper limb. All the patients had excision with satisfactory results during the period of follow up that ranged from 6 months to 3 years (mean 13 months). Conclusion: BCC is an uncommon lesion in our region. Albinism and solar radiation were identified risk factors. Most of the albinos presented 3 decades earlier than the darkly pigmented. Early institution of preventive measures, early diagnosis, and treatment would result in better outcome.

引用

International Journal of Clinical Medicine 2012年第5期3卷 426-430页

作者： Maurice Asuquo Mark Umoh victor nwagbara Gabriel Ugare Cyril Agbor Emmanuel Japhet Department of Surgery University of Calabar Teaching Hospital Calabar Nigeria

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.

Evaluating the Potential Effectiveness of Moringa oleifera Seeds Biomass as an Adsorbent in the Removal of Copper (Cu) in Water

引用

Journal of Geoscience and Environment Protection 2022年第3期10卷 120-143页

作者： victor Uzoma nwagbara Franklin Obeng Sika William Azuka Iyama Kayini Chigayo Habauka Majority Kwaambwa Department of Civil and Environmental Engineering Namibia University of Science and Technology Windhoek Namibia School of Nursing Bronx Lehman College New York USA Institute of Geosciences and Space Technology River State University Port Harcourt Nigeria Department of Natural and Applied Sciences Namibia University of Science and Technology Windhoek Namibia

This study was based on the evaluation of the potential effectiveness of Moringa oleifera seeds biomass as a biosorbent in the removal of copper (Cu) in water which was justified by the level of toxicity, environmental unfriendliness and costly nature of chemical coagulants presently used. Fourier transform infrared (FTIR) analysis was used to identify the Moringa oleifera seeds biomass functional groups present in the adsorption of metal ions and found to be the carboxylic acid and amine functional groups (-COOH and -NH). The effects of contact time, adsorbent dosage, metal ion concentration and pH were studied. The maximum adsorption capacity at pH 5, room temperature and 0.8 g dosage was 70% for Cu(II). The adsorption data fitted better to the Langmuir than the Freundlich models as the sorption capacity (qm) of Moringa oleifera seeds biomass for Cu(II) was 3.64 mg/g. The separation factor (RL) was within the range of 0 and 1 which showed that the Cu(II) biosorption processes were favourable for Moringa oleifera biosorbent. The results showed that Moringa oleifera seed biomass is an effective adsorbent in the removal of the studied heavy metals in water. The effective pH for the Cu(II) removal was 5.0 as equilibrium was achieved practically in 35 min. The quantitative analysis of defatted Moringa oleifera should be studied in order to have a fair mixing ratio between Moringa oleifera seeds biomass and the adsorbate. There is also the ardent need to work on environmentally friendly disposal of adsorbent after saturation of adsorbent by analyte to avoid secondary pollution.

Blunt Abdominal Trauma in a Teaching Hospital, Calabar, Nigeria

引用

International Journal of Clinical Medicine 2012年第7期3卷 693-696页

作者： Maurice Asuquo victor nwagbara Mark Umoh Gabriel Ugare Cyril Agbor Emmanuel Japhet Anthonia Ikpeme Department of Radiology University of Calabar Teaching Hospital Calabar Nigeria Department of Surgery University of Calabar Teaching Hospital Calabar Nigeria

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.

Anal Cancer in a HIV Sero-Positive Bisexual Bachelor—A Case Report and Literature Review

引用

Case Reports in Clinical Medicine 2018年第12期7卷 601-607页

作者： victor nwagbara M. E. Asuquo J. A. Ashindoitiang S. O. Akpan Department of Surgery University of Calabar Calabar Nigeria

Anal cancer, especially squamous cell carcinoma (SCC) variety, is evolving with rising incidence globally. This is due to the increasing adoption of risky life styles and social habits even in populations with rare occurrences previously. This case report aims to expose risk factors exhibited by a patient recently managed for anal cancer in our facility before his demise. Early exposure to bisexual orientation, receptive anal intercourse and multiple sexual partners, are notable high risk factors for the development of anal SCC. The permissive role of smoking, illicit drug and alcohol use enhances the disease occurrence. Acquisition of human immune-deficiency virus (HIV) sero-positive status further reduces the body’s immune competence and enhances early age of onset as well as accelerates development of anal SCC. Proper history exploring the risk factors, physical/anorectal examination and histological analysis, are vital for proper diagnosis and staging which guides appropriate treatment with chemo-radiation as mainstay.

Cutaneous Metastatic Disease: Case Series in a Tropical Setting

引用

Case Reports in Clinical Medicine 2016年第1期5卷 25-31页

作者： Maurice E. Asuquo Aniefon N. Umana victor I. C. nwagbara Martin Nnoli Theophilus Ugbem Department of Surgery University of Calabar Calabar Nigeria Department of Otorhinolaryngology University of Calabar Calabar Nigeria Department of Pathology University of Calabar Calabar Nigeria

Background: Cutaneous metastasis is valuable though with infrequent occurrence in clinical practice. It is of esteem value in diagnosis as well as treatment of cancer due to the ease of accessibility for clinical examination and biopsy. Case Series: This is a presentation of 5 consecutive patients with histologic diagnosis of cutaneous metastatic malignancies at the University of Calabar Teaching Hospital, (UCTH), Calabar, Nigeria from 2010 to 2013. They were studied in an attempt to evaluate the clinical significance of cutaneous metastatic nodules/disease in a tropical setting. This was compared with total cutaneous malignancies and total malignancies seen over the same period. Conclusion: The spectrum in the reported cases ranged from localised and barely noticeable nodules to generalised nodules. Clinicians are urged to show renewed interest in cutaneous nodules in view of the estimable value by subjecting such for histological evaluation.

Complicated Left-Sided Amyand’s Hernia in an 18-Month-Old Boy: A Case Report and Literature Review

引用

Case Reports in Clinical Medicine 2016年第1期5卷 1-5页

作者： victor I. C. nwagbara Maurice E. Asuquo Ayi E. Archibong Emmanuel Etuk Ijeoma O.

The rare finding of the vermiform appendix within an inguinal hernia sac is known as Amyand’s hernia. It was first described by Claudius Amyand in 1735, in a right inguinal hernia. A much rarer find is a left-sided Amyand’s hernia. This is a report of a case of complicated left-sided Amyand’s hernia in an eighteen month old male child. He presented as an emergency with an obstructed inguino-scrotal hernia and the diagnosis of Amyand’s hernia was made intra-operatively. He made uneventful recovery after surgery. Treatment options depend on findings during operation and clinical status of the patient.
