A Review on Laboratory Diagnosis of Mycobacterium tuberculosis

Abstract: Tuberculosis remains the major public health concern worldwide responsible for about 1.6 million deaths and 0.3 million co-infected with Human immunodeficiency virus (HIV) annually. Mycobacterium is the causative agent of tuberculosis infection and is transmitted principally through air when an infected person coughs, talks, sneezes etc. This infection can be diagnosed using different Microbiological, Molecular and Immunological techniques including, sputum smear microscopy, sputum culture, nucleic-acid amplification test (NAAT), genotyping assay, tuberculin skin test (TST), interferon-gamma release assay (IGRAs) etc. These techniques vary in sensitivity and specificity as well as the ease with which they are carried out. World Health Organisation (WHO) encourages the use of techniques that are sensitive, patient-friendly, and those which produce accurate results in any clinical setting world-wide. Hence, this review highlights smear microscopy and incorporation of more rapid and sensitive diagnostic techniques such as Gene Xpert, IGRAs and urinary antigen analysis in clinical setting in the detection of Mycobacterium. These techniques show high sensitivity, are less time consuming do not require a repeat for a single result, some are able to differentiate latent and active TB infections, and have the capacity to be used to screen people unable to expectorate. This review encourages the incorporation of smear microscopy, GeneXpert, IGRAs, urinary antigen analysis into routine laboratory diagnosis especially in high TB burden countries. It is believed that high level of sensitivity and less time used in producing results display by these techniques will yield reduction in mortality rate, decline in static nature of TB status and possibly zero TB 2020 proposed by WHO.

Effect of damp and treatment methods on residential buildings in calabar metropolis of cross river state

Abstract: The main purpose of this study was to investigate the effect of damp and treatment methods on residential buildings in Calabar Metropolis of Cross River State. Damp is a pervasive problem for residential buildings. It is at times expressed in the most unlikely places under unexpected and unsettling conditions due to heavy rainfall. It is usually expressed at home, market, and neighborhood or within community. At different-occasions damp had cause many damages to school properties, destruction of roads especially during rainy season. To achieve the purpose of this study two research questions were formulated to direct the study. Survey research design was adopted for the study. A sample of one hundred respondents was randomly selected for the study. The selection was done through the simple random sampling technique. This was to give equal and independent opportunities to all the respondents to be selected for the study. The questionnaire was the instrument used for data collection. The instrument was subjected to face validation by experts in measurement and evaluation. The reliability estimate of the instrument was established through the test re-test reliability method. The results of the respondents reveal that damp and treatment method significantly influence residential buildings in Calabar Metropolis. Based on the findings, it was recommended among others that the State government should construct good drainage system to enhance the free flow of stagnant water during or after rainfall in order not to cause damages to the buildings.

Regression equations for estimating stature from anthropometric measurements of foot length and breadth in adults of efik ethnic group in cross river state

Abstract: INTRODUCTION: Estimation of stature is an important factor in forensic studies and occupies a foremost position in anthropometric research. The aim of the present work was to determine the reliability of foot dimensions in estimating stature in adult of Efik ethnicity in Cross River State. MATERIALS AND METHODS: The individuals comprised of 600 adult indigenes (300 males and 300 females) of Efi k ethnic group in Cross River State between the ages of 18–45 years. Student's t-test, Pearson's correlation, and Regression analysis were used to estimate the stature in the study population. RESULTS: Our results showed that stature in males had a mean value of 165.40 cm, whereas in females, it was 161.67 cm. More so, foot dimensions studied showed sexual dimorphism. Foot length in male individuals was 25.30 cm, while in females, foot length measured was 23.48 cm. Furthermore, the mean foot breadth in males was 9.20 cm, while in females, foot breadth was 8.37 cm. Statistical analysis revealed that the difference in foot length and foot breadth between males and females was statistically significant (P CONCLUSION: Regression equations formulated showed that foot breadth was a better predictor of stature in males while foot length was more reliable in predicting stature in females of Efik descent. These findings will be of immense benefit to physical anthropology and forensic studies Kteuydwieos rodfs t:he study environment.

Degradation and preservation practices of information resources in academic libraries in Cross River State, Nigeria

Abstract: The purpose of this study was to studyinvestigate degradation and preservation practices of information resources in academic libraries in Cross River State, Nigeria.It examined the nature and causes of degradation of information resources, strategies used in their control, and constraints limiting effective preservation.The study adopted survey design. The population for the studyconsisted of all information resources in the five academic libraries in the state. Purposivesampling technique was used in selecting 202 respondents who suppliedthe information used for the study. A structured questionnaire was used for data collection and the data were analyzed using t-test. The result of the analysis showed that all the four null hypotheses were rejected. This means that the nature of information resources degradation in academic libraries in Cross River State is significantly high. The study also revealed that barriers to effective preservation of information resources in academic libraries in Cross River State are significantly high. Based on the findings,the study recommended among others that academic libraries should recruit adequate and trained manpower in the libraries for effective preservation programmes and activities.Academic libraries should consider various methods that could be applied to curb degradation of information resources in their holding. And,adequate annual budget allocationshould be provided for preservation programmes in academic libraries in the state.
