Journal of Tuberculosis Research (JTR) , 2019, DOI: 10.4236/jtr.2019.72010
Abstract: Introduction: Tuberculosis (TB) still causes significant morbidity and mortality amongst adults and children despite all the efforts which have been put into the control of the disease. However, the prevalence of the disease in school age children is unknown because of scarcity of TB screening surveys in Nigerian schools. The aim of this study was to evaluate the proportion of school age children treated for TB in the Directly Observed Treatment Short Course (DOTS) clinic of University of Port Harcourt Teaching Hospital (UPTH). Methods: The records of all children 6 to 18 years who were treated in the DOTS clinic from 2011 to 2014 were reviewed. Information sought included age, sex, sputum Acid Fast Bacillus (AFB) status, Human Immunodeficiency Virus (HIV) status and treatment outcome. Results: One hundred and forty children aged 6 to 18 years were treated in the University Port Harcourt Teaching Hospital DOTS clinic, representing 41.79% of childhood TB cases seen over the study period. Seventy one (50.71%) patients were males and 69 (49.29%) were females. Their mean age was 12 ± 3.86. Thirty-one (22.14%) had smear positive TB. Sputum smear positivity was commonest (54.84%) among those who were 16 years and above compared to the other age groups and this is statistically significant (x2 = 17.72, p = 0.001). Forty-one (35%) patients were HIV positive and 6 (4.29%) were positive for both HIV and AFB. Ninety (64.29%) patients recovered fully following treatment, 48 (34.29%) were referred to other DOTS centres and 2 (1.43%) died. Gender, age group, AFB and HIV status showed no relationship with treatment outcome. Conclusion: School age children 6 to 18 years made up a large proportion of childhood TB cases seen within the study period in the DOTS clinic. More than one third of them were HIV/TB co-infected. An effective School Health Services should be established in schools in Port Harcourt to curb the spread of TB and other communicable diseases within the schools.

International Journal of Clinical Medicine (IJCM) , 2018, DOI: 10.4236/ijcm.2018.96042
Abstract: Background: HIV encephalopathy (HIVE) is associated with cognitive impairment in children with HIV infection, early diagnosis and initiation of HAART may reduce the morbidity associated with HIVE. Objective: To determine the prevalence of HIVE and associated comorbiditiesin children at the UPTH. Methodology: This was a retrospective study carried out from January to June 2017. The case notes of all HIV positive children presenting to the Paediatric Department of the University of Port Harcourt Teaching Hospital (UPTH) were studied. Children who met the diagnostic criteria for HIVE according to the Centre for Disease Control (CDC) definition were selected. The socio-demographic characteristics of the patients, mode of HIV transmission, CD4 count and associated comorbidities in these children were retrieved from the case notes. Obtained data was analyzed using Epi Info version 7.2. Comparisms of subgroups was carried out using the chi square test while statistical significance at 95% confidence interval was p value < 0.05. Results: A total of thirty five out of the 196 HIV positive children presenting to the hospital had HIV encephalopathy (HIVE) giving a prevalence rate of 17.9%. Of these 35 children, 18 were males and 17 females, giving a male to female ratio of 1:1. The mean age of the children was 5.7 ± 3.1 years. The mean age for the males was 6.4 ± 3.2 years and 5.0 ± 2.8 years for the females. There was no statistically significant difference observed between the sexes (t = 1.35, p = 0.187). Thirty (85.7%) of the patients with HIVE were on HAART at diagnosis. The mean age at diagnosis of HIV was 3.2 ± 3.1 years and the mean age at diagnosis of HIV encephalopathy was 3.4 ± 3.2 years. The documented route of transmission for all the subjects was mother-to-child-transmission (MTCT). Seventy five percent of the children were breastfed from birth and at 6 months all the mothers had discontinued breastfeeding. The mean CD4 count was 1053 ± 630 cells/ml. Tuberculosis was the most prevalent co-morbidity occurring among the patients. Conclusion: The prevalence of HIVE in children at the UPTH is high and Tuberculosis is the commonest comorbidity. Early infant diagnosis, use of modern diagnostic tool and early initiation of HAART are advocated to reduce its associated morbidity.

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104122
Abstract:
Background: Health care workers especially interns may be at increased health risk due to exposure to blood and body fluids. Objective: To determine the prevalence of occupational exposure to blood and body fluids (EBBF) among interns at the University of Port Harcourt Teaching hospital (UPTH). Methodology: This cross-sectional study was carried out among interns at the UPTH. Informed written consent was obtained. The obtained data from a self-administered questionnaire and Infection Control Team records were analysed using SPSS version 21 and are presented as prose and tables. Results: Eighty four interns were studied giving a response rate of 93.3%: 40 (47.6%) were males while 44 (52.4%) were females giving a male:female ratio of 1:1.1. Thirty two (38.1%) were aware of the availability of sharp bins, 55 (65.5%) recapped and discarded into waste bins while 4 (4.8%) discarded into sharp bins without re-capping. Prevalence of EBBF was 89.3%. Thirty one (41.4%) had Blood and Body Fluid Splash (BBFS), 22 (29.3%) had Needle Stick Injury (NSI) while 22 (29.3%) had combined NSI and BBFS. Thirteen (29.5%) of the NSI occurred during rotation in Paediatrics. Seventeen (32.1%) and 16 (30.2%) of BBFS occurred during Obstetrics and Gynaecology and Paediatrics rotation respectively. Eleven (25%) reported the NSI to the Infection control team (ICT) and 3 (27.3%) completed 28 days of Highly Active Anti-Retroviral Therapy (HAART). Common reason for not reporting was not been aware of the Infection Control Team (ICT) in 10 (30.3%). Conclusion: There is a need for improved training and close supervision of interns.
The global financial crisis: origin, contagion and impacts on Ethiopia
I Paul
Journal of Business and Administrative Studies , 2010,
Abstract: The financial crisis that erupted in September 2008—following more than two years of financial turmoil has become global crisis for the world economy. An attempt is made in this study to assess the possible causes of the origin, contagion and impact of the current global financial crisis with particular emphasis on Africa and Ethiopia. It also provides a summarized historical overview of past global financial crises in view of the economic theories of financial crises. The study utilizes the fundamental economic theories related to financial crisis to depict and illustrate the bigger picture. The paramount importance of this study is a detailed analysis of the current global financial crisis, and its wide ranging impacts by creating a clear link with past financial crises in different regions of the world. The method followed throughout this paper is qualitative and descriptive in nature. The transmission channels for the Ethiopian economy in the study are the knock on effects, external sector and commodity prices, investment, official transfers and remittance and the impact on the flower industry.
Magneto-elastic quantum fluctuations and phase transitions in the iron superconductors
I. Paul
Physics , 2011, DOI: 10.1103/PhysRevLett.107.047004
Abstract: We examine the relevance of magneto-elastic coupling to describe the complex magnetic and structural behaviour of the different classes of the iron superconductors. We model the system as a two-dimensional metal whose magnetic excitations interact with the distortions of the underlying square lattice. Going beyond mean field we find that quantum fluctuation effects can explain two unusual features of these materials that have attracted considerable attention. First, why iron telluride orders magnetically at a non-nesting wave-vector $(\pi/2, \pi/2)$ and not at the nesting wave-vector $(\pi, 0)$ as in the iron arsenides, even though the nominal band structures of both these systems are similar. And second, why the $(\pi, 0)$ magnetic transition in the iron arsenides is often preceded by an orthorhombic structural transition. These are robust properties of the model, independent of microscopic details, and they emphasize the importance of the magneto-elastic interaction.
Interaction Correction of Conductivity Near a Ferromagnetic Quantum Critical Point
I. Paul
Physics , 2007, DOI: 10.1103/PhysRevB.77.224418
Abstract: We calculate the temperature dependence of conductivity due to interaction correction for a disordered itinerant electron system close to a ferromagnetic quantum critical point which occurs due to a spin density wave instability. In the quantum critical regime, the crossover between diffusive and ballistic transport occurs at a temperature $T^{\ast}=1/[\tau \gamma (E_{F}\tau)^{2}]$, where $\gamma$ is the parameter associated with the Landau damping of the spin fluctuations, $\tau$ is the impurity scattering time, and $E_{F}$ is the Fermi energy. For a generic choice of parameters, $T^{\ast}$ is few orders of magnitude smaller than the usual crossover scale $1/\tau$. In the ballistic quantum critical regime, the conductivity has a $T^{(d-1)/3}$ temperature dependence, where $d$ is the dimensionality of the system. In the diffusive quantum critical regime we get $T^{1/4}$ dependence in three dimensions, and $\ln^2 T$ dependence in two dimensions. Away from the quantum critical regime we recover the standard results for a good metal.
Nesting Induced Large Magnetoelasticity in the Iron Arsenide Systems
I. Paul
Physics , 2013, DOI: 10.1103/PhysRevB.90.115102
Abstract: A novel feature of the iron arsenides is the magnetoelastic coupling between the long wavelength in-plane strains of the lattice and the collective spin fluctuations of the electrons near the magnetic ordering wavevectors. Here, we study its microscopic origin from an electronic model with nested Fermi pockets and a nominal interaction. We find the couplings diverge with a power-law as the system is tuned to perfect nesting. Furthermore, the theory reveals how nematicity is boosted by nesting. These results are relevant for other systems with nesting driven density wave transitions.

Aharonov-Bohm oscillations in the local density of states
A. Cano,I. Paul
Physics , 2009, DOI: 10.1103/PhysRevB.80.153401
Abstract: The scattering of electrons with inhomogeneities produces modulations in the local density of states of a metal. We show that electron interference contributions to these modulations are affected by the magnetic field via the Aharonov-Bohm effect. This can be exploited in a simple STM setup that serves as an Aharonov-Bohm interferometer at the nanometer scale.
