Service level delivery of municipal and private water sources in Olodi-Apapa, Ajeromi-Ifelodun LGA, Lagos

The service level delivery of municipal water supply and private groundwater sources in Olodi-Apapa, Lagos was evaluated. Reconnaissance survey, co-ordinates and heights above sea level of water sample points were obtained. Structured questionnaires retrieved from two hundred and forty seven (247) inhabitants (98.8%) were analyzed. The result shows a low income area with 72.9% in room apartments, 90.3% uses untreated water supply, with only 6.5% from the municipal source, while private borehole and well accounts for 55.8% and 37.7% respectively. Use of generating set for water abstraction was by 77.3%, while 93.5% do not have access to public water supply, 100% of the sources have high calcium hardness and over 60% have high chloride content. Municipal micro water works limitations include expansion, electricity supply, and good network of public standing pipes

Fulminant necrotizing fasciitis following the use of herbal concoction: a case report

<p>Abstract</p> <p>Introduction</p> <p>Necrotizing fasciitis is a rare and life-threatening rapidly progressive soft tissue infection. A fulminant case could involve muscle and bone. Necrotizing fasciitis after corticosteroid therapy and intramuscular injection of non-steroidal anti-inflammatory drugs has been reported. We present a case of fulminant necrotizing fasciitis occurring in a patient who used a herbal concoction to treat a chronic leg ulcer.</p> <p>Case presentation</p> <p>A 20-year-old Ibo woman from Nigeria presented with a three-year history of recurrent chronic ulcer of the right leg. She started applying a herbal concoction to dress the wound two weeks prior to presentation. This resulted in rapidly progressive soft tissue necrosis that spread from the soft tissue to the bone, despite aggressive emergency debridement. As a result she underwent above-knee amputation.</p> <p>Conclusion</p> <p>The herbal concoction used is toxic, and can initiate and exacerbate necrotizing fasciitis. Its use for wound dressing should be discouraged.</p

Semantics-based clustering approach for similar research area detection

The manual process of searching out individuals in an already existing research field is cumbersome and time-consuming. Prominent and rookie researchers alike are predisposed to seek existing research publications in a research field of interest before coming up with a thesis. From extant literature, automated similar research area detection systems have been developed to solve this problem. However, most of them use keyword-matching techniques, which do not sufficiently capture the implicit semantics of keywords thereby leaving out some research articles. In this study, we propose the use of Ontology-based pre-processing, Latent Semantic Indexing and K-Means Clustering to develop a prototype similar research area detection system, that can be used to determine similar research domain publications. Our proposed system solves the challenge of high dimensionality and data sparsity faced by the traditional document clustering technique. Our system is evaluated with randomly selected publications from faculties in Nigerian universities and results show that the integration of ontologies in preprocessing provides more accurate clustering results

Thread embedded into penile tissue over time as an unusual hair thread tourniquet injury to the penis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Hair thread tourniquet syndrome has been recognized since the 1960s. Since then, sporadic reports have appeared in the literature describing different degrees of strangulation and/or amputation of the penis caused by a hair thread being inadvertently tied around the penis.</p> <p>Case presentation</p> <p>A 9-year-old boy presented with a 3-year history of hair thread tourniquet injury to his penis. Instead of the usual strangulation or amputation, the tourniquet had become embedded into the penile tissue, manifesting with exuberant granulation tissue and a tight urethral stricture. At surgery, the intact tourniquet was still in place, embedded in dense fibrous tissue and associated with a dense urethral fibrosis which measured about 2 cm long. The tourniquet was divided and removed, the fibrotic urethra excised and a distal penile pedicled skin flap used to perform a single-stage substitution urethroplasty. The patient has been voiding well for 28 months.</p> <p>Conclusion</p> <p>This case is unusual and is the first report of its kind. It is also the first report of a hair thread tourniquet as the cause of pediatric penile injury in Nigeria.</p

EPIDEMIOLOGY OF BACTERIA COLONIZATION AND ICU-ACQUIRED INFECTION IN A NIGERIAN TERTIARY HOSPITAL

Background: Health care associated infection (HCAI) or Hospital acquired infection is associated with significant morbidity, mortality and cost. The incidence is about 6% and disproportionately higher in critically ill patients who may have been immune-compromised with many invasive procedures already performed. Prevention of HCAI and appropriate management of patients in the intensive care unit (ICU) requires knowledge on the pattern of microbial colonization and infections. The aim of this preliminary study was to provide current data on the pattern of ICU acquired infections in our hospital. Patients and Methods: It was a cross sectional study of patients admitted into the ICU who were expected to stay longer than 48hrs between July 2011 and September 2012. Urine, blood, and tracheal aspirate were collected on days 1, 3 and 5 for microbiological studies. All patients involved in the study had urethral catheter in-situ and received mechanical ventilation in the ICU. Results: Fifty-nine patients were recruited into the study. The mean age of the patients was 30.08 + 19.9yr; while the reasons for admissions were respiratory failure (59.3%), cardiovascular instability, trauma and neurological diseases. About 30% of the samples taken from the study sites on arrival in the ICU had positive culture yields. Organisms cultured included Klebsiella oxytoca, Staphylococcus aureus, and Pseudomonas aeruginosa. The urinary tract had the highest number of isolated organisms- 9(60%), followed by equal number of isolated organisms-3(20%) in the blood and respiratory tract. Eleven (73.3%) of the organisms isolated were Gram-negative bacteria, and 4 (26.7%) were Gram-positive cocci. The commonest bacteria isolates were Staphylococcus aureus (4/26.7%) and Klebsiella oxytoca (4/ 26.7%). A total of 15 ICU- acquired infections were detected in 9 of 59 patients. Conclusion: The HCIA infection rate was 15%, and urinary tract infections (UTI) was the commonest hospital acquired infection in our ICU. Klebsiella oxytoca and Staphylococcus aureus were the commonest organisms

Introduction Genomic research and neurobiobanking are expanding globally. Empirical evidence on the level of awareness and willingness to donate/share biological samples towards the expansion of neurobiobanking in sub-Saharan Africa is lacking. Aims To ascertain the awareness, perspectives and predictors regarding biological sample donation, sharing and informed consent preferences among community members in Ghana and Nigeria. Methods A questionnaire cross-sectional survey was conducted among randomly selected community members from seven communities in Ghana and Nigeria. Results Of the 1015 respondents with mean age 39.3 years (SD 19.5), about a third had heard of blood donation (37.2%, M: 42.4%, F: 32.0%, p = 0.001) and a quarter were aware of blood sample storage for research (24.5%; M: 29.7%, F: 19.4%, p = 0.151). Two out of ten were willing to donate brain after death (18.8%, M: 22.6%, F: 15.0%, p&lt;0.001). Main reasons for unwillingness to donate brain were; to go back to God complete (46.6%) and lack of knowledge related to brain donation (32.7%). Only a third of the participants were aware of informed consent (31.7%; M: 35.9%, F: 27.5%, p&lt;0.001). Predictors of positive attitude towards biobanking and informed consent were being married, tertiary level education, student status, and belonging to select ethnic groups. Conclusion There is a greater need for research attention in the area of brain banking and informed consent. Improved context-sensitive public education on neurobiobanking and informed consent, in line with the sociocultural diversities, is recommended within the African sub region

The Emerging Story of Disability Associated with Lymphatic Filariasis: A Critical Review

Globally, 40 million people live with the chronic effects of lymphatic filariasis (LF), making it the second leading cause of disability in the world. Despite this, there is limited research into the experiences of people living with the disease. This review summarises the research on the experiences of people living with LF disability. The review highlights the widespread social stigma and oppressive psychological issues that face most people living with LF-related disability. Physical manifestations of LF make daily activities and participation in community life difficult. The findings confirm the need for the Global Programme to Eliminate Lymphatic Filariasis (GPELF) to support morbidity management activities that address the complex biopsychosocial issues that people living with LF-related disability face

The Role of Ethnic Directors in Corporate Social Responsibility: Does Culture matter? The Cultural Trait Theory Perspectives

This paper investigates the effect of cultural differences between ethnic directors on corporate social responsibility (CSR) of Public Liability Companies (PLCs) in Nigeria. Using the cultural trait theory, the study focuses on how the ethnic directors are influenced when making decisions concerning CSR. Adopting multiple regression analysis of data, the study investigates the three major ethnic groups (Yoruba, Igbo and Hausa) and finds cultural differences between the ethnic directors affect the adoption of CSR. Empirical results indicate that ethnic directors (Yoruba, Igbo and Hausa) were positively and significantly related to CSR. The paper contributes to the corporate governance and CSR debate concerning how ethnic directors’ decisions impact on CSR activities, particularly on the directors who are individualistic and collectivists towards CSR

The practice of hepatocellular cancer surveillance in Nigeria

Background: Hepatocellular cancer is a disease of global and public health importance due to the widespread distribution of risk factors and associated high case fatality. Hepatocellular Cancer (HCC) in Sub-Saharan Africa is commonly seen among the younger age groups (&lt;45 years) who present mostly in the terminal stage, when the disease is not amenable to any curative therapy. Hepatocellular Carcinoma surveillance employs the use of simple, cheap and readily available investigations, to detect early curable cancer in individuals with risk factors for HCC.Objectives:The aim of this study is to assess the practice of hepatocellular cancer screening among physicians.Methodolgy:This is a nationwide online survey carried out among physicians who care for patients with HCC. A questionnaire was sent out via a web link to all consenting doctors in Nigeria. The responses were collated in a cloud-based application and data was analysed using Epi-info version 20.Results:Atotal of 218 respondents, 142 were males (65.1 %) with a mean age of 37.6 ± 5.7 years. The modal age group was 31-40 years 153 (69.5%). The main factors considered as a hindrance to surveillance were; the cost of the tests (57.7%), failure of return of patients (50.5%) and not being aware of a surveillance program (45.2 %). The majority of the respondents were Gastroenterologists and Family Physicians. 54% of the gastroenterologists and 64% of the family physicians have never offered HCC surveillance to their patients.Conclusion:This survey highlights a knowledge gap in HCC surveillance among physicians. There is a need to make HCCsurveillance a daily routine among patients at risk by all physicians. Keywords: Surveillance, Hepatocellular Carcinoma, HBV, HCV, Cancer screening
