Hepatitis B virus (HBV) infection has been recognized globally as a major public health challenge necessitating a global call for increased awareness, patients' identification, and development of activities for prevention and control of the disease. Consequently, massive health education campaigns and screening exercises have been mounted globally to mark the World Hepatitis Day (WHD).As part of WHD 2016 activities, we undertook a survey and screening of health care workers in order to raise awareness, identify patients and contribute to the Global Health Strategy goal of eliminating HBV infection by the year 2030.This was a cross-sectional analytical study done at the University of Nigeria Teaching Hospital, Ituku-Ozalla, Enugu, Nigeria. Hospital workers voluntarily presented themselves to be screened using a rapid test kit and completing a semi-structured investigator-administered questionnaire.A total of 3123 participants were studied. The mean age of the participants was 39.4 ± 9.6 years. The seroprevalence of HBV infection was 2.3%. Most (97.0%) of the participants had previously heard about HBV infection and over two thirds (68.1%) could correctly identify risk factors and modes of transmission of HBV. Twenty-eight and a half percent of the participants knew their hepatitis B virus status prior to the study.The seroprevalence of HBV among healthcare workers in Enugu, Nigeria is relatively low compared to figures from other African countries. The healthcare workers have considerable knowledge of the disease. However, the observed knowledge gaps in awareness and screening need to be addressed.

Urolithiasis is a global disease condition secondary to a variety of factors, and sometimes associated with serious complications. Determination of stone composition is important in delineating causative factors. Knowledge of causative and precipitating factors aids patient management and prevention of recurrence.The authors' aim was to evaluate the practice and perspective of doctors regarding chemical analysis of stones in management of urolithiasis.This comparative cross-sectional study was done between December 2016 and May 2017 in two teaching hospitals in South-East, Nigeria. Data were collected using self-administered questionnaires.In all, 88 doctors with mean (standard deviation) age of 37.3 (9.5) years participated in the study. Urinary bladder stones were the most frequently managed, 51 (58.0%); 45 (51.1%) participants do not routinely send stones for chemical analysis. All respondents (100%) agreed that stone analysis is beneficial to patient management.This study showed that in spite of all respondents affirming that chemical analysis of uroliths is beneficial to patient management, more than half of respondents do not routinely send stones for analysis.

The critically ill patient undergoes rapid changes in the internal milieu requiring quick intervention. Point of care testing has been shown to be valuable in the early diagnosis and management of such patients.This study determined the agreement between I-STAT Abbot point of care testing with standard laboratory testing in the analysis of electrolytes and glucose concentrations in critically ill patients.The study was performed in a Sub-Saharan Tertiary Teaching Hospital in critically ill patients. Electrolyte and glucose analysis were measured with I-STAT Abbot Analyzer unit with parallel blood specimens (n = 30) tested in the laboratory on an ion-selective electrode, SFRI analyzer ISE 6000.There was no significant difference in mean sodium, potassium, chloride and glucose between I-STAT POCT and standard laboratory measurements. The agreement between POCT and laboratory glucose was good p(c) = 0.967, mean difference of 0.79 and 95% limit of agreement from -3.83 to +5.107 mmol/L, p = 0.733. Bicarbonate was moderate (p) = 0.637, mean difference of 1.95 and 95% limit of agreement from -4.294 to +0.394 mmol/L, p = 0.101. There was moderate agreement for sodium (p(c)) = 0.32, mean difference of 5.8 and 95% limit of agreement from -0.378 to +11.98 mmol/L, p = 0.064. Agreement for potassium was moderate (p(c)) = 0.439, mean difference of 0.15 and limit of agreement from -0.401 to +0.701 mmol/L, p = 0.588. There was, however, a significant difference in mean chloride, and BUN values; chloride (p(c)) = 0.0796, mean difference of 13.8 and 95% limit of agreement from -7.55 to + 20.015 mmol/L. Blood urea nitrogen (p(c)) = 0.064, mean difference of 18.55 and 95% limit of agreement from -30.126 to +6.974 mmol/L.The mean sodium, potassium, glucose and bicarbonate were comparable with moderate to good agreement between I-STAT POCT and ISE 6000 Analyzer. Though, the mean BUN and chloride levels between the analytical methods differ significantly.
