The impetus for this research work arose from alleged signs of Lead (Pb) poisoning from Medicines Sans Frontiers (Doctors without Borders).These poisonings were narrowed down to areas of solid minerals mining and extraction in Northern Nigeria. The aim of this research work is to identify mining Sites with ores having high Pb concentration. Fifteen samples were collected from areas located at approximately latitudes 𝟶𝟶70𝟶8.69𝟶ˈE and longitudes 𝟶90 34ˈ224ˈˈN and interrogated using Proton induced X-ray emission (PIXE) technique for their elemental content. PIXE was chosen because of its sample nondestructive and it does not contaminate the environment. The result obtained varied between 24.3 – 632303.3 ppm. The world Health Organization recommends that sites with Pb concentration above 400 ppm are inimical to human health and ordered that children be evacuated from such areas. Exposure to Pb poisoning may cause anemia, weakness, and Kidney and brain damage; particularly in children.

Abstract Total reflection X-ray fluorescence spectrometry and chemical preconcentration have been applied for multi-elemental analysis of Damascus drinking water. Water was taken directly from taps of several city sectors and analyzed for the following trace elements: Ti, V, Cr, Fe, Co, Ni, Cu, Zn, Se and Pb. The detection limits were found to be in the range of 0.1 to 0.4 µg/L. The mean levels of trace elements in the Damascus drinking water were below the World Health Organization drinking water quality guidelines.

According to the World Health Organization (WHO), 71 million people were living with Hepatitis C virus (HCV) infection worldwide in 2015. Each year, about 399,000 HCV-infected people succumb to cirrhosis, hepatocellular carcinoma, and liver failure. Therefore, screening of HCV infection with simple, rapid, but highly sensitive and specific methods can help to curb the global burden on HCV healthcare. Apart from the determination of viral load/viral clearance, the identification of specific HCV genotype is also critical for successful treatment of hepatitis C. This critical review focuses on the technologies used for the detection, discrimination, and genotyping of HCV in clinical samples. This article also focuses on advantages and disadvantages of the reported methods used for HCV detection, quantification, and genotyping.

Participation in the World Health Organization (WHO) is a multifaceted matter and should be understood as not only referring to the governance of WHO, but also to its scientific and technical work as well as its collaborative efforts towards advancing global public health more generally. The article is concerned, in particular, with the legal and political framework surrounding attendance and participation of states and various entities in the governing bodies of the Organization, at the global and regional level. It shows that participation in the governance of WHO is still today a domain reserved to the determination of its Member States. At the same time, solutions have been found and continued efforts are necessary to take into account geopolitical considerations and to ensure a meaningful and inclusive participation of all relevant actors in global health discussions.

Background: Medicinal plants have been used to treat various diseases for several years throughout the world. Xylanthemum macropodum is a medicinal plant with a vast application as a home remedy in Balochistan. Objective: The current study was conducted to determine the levels of essential and non-essential elements in Xylanthemum macropodum collected from Quetta (Balochistan, Pakistan). Methods: Analysis was conducted for eleven elements by using atomic absorption spectrophotometer and flame photometer. Results: The essential and non-essential elements that were detected in Xylanthemum macropodum are K, Na, Ca, Fe, Cu, Co, Ni, Mn, Cr, Cd and Pb, respectively. The result of the concentration of determined elements are in the order of K> Na> Ca> Fe> Cu> Co> Ni> Mn> Cd> Cr> Pb in Xylanthemum macropodum 3000> 1600> 790.25> 92.36> 85.31> 49.24> 40.94> 20.94> 6.655> 1.61> 1.18 µg/g respectively. Conclusions: Mn, Na and Pb were found within the permissible limit given by World Health Organization, while Ca, Cu, Fe, Ni, Cd and Cr were beyond the permissible limits. However, there is no permissible limit for K and Co.

Background: The Public Health Emergency of International Concern by the World Health Organization (WHO) declared novel Coronavirus (nCoV-2019) outbreaks in 2019 and is pandemic. Methods: This research work made an analysis of the nCoV-2019 outbreak in India solely based on a mathematical model. Results: The historical epidemics in the world are plague, AIDS, Swine flu, ebola, zika virus, Black Death and SARS. Considering the model used for SARS 2003, the present research on Covid-2019 estimates characteristics of rate of infectious (I) and rate of recovery(R) which leads to estimation the I and R leads to predict the number of infectious and recovery. Through ruling out the unpredictable, unreasonable data, the model predicts that the number of the cumulative 2019-nCoV cases may reach from 3398458(mid of May) to 15165863, with a peak of the unrecovered infective (2461434-15165863) occurring in late April to late July. In this paper we predicate how the confirmed infected cases would rapidly decrease until late March to July in India. We also focus how the Government of Odisha (a state of India) creates a history in the protective measures of Covid-19. Conclusion: The growing infected cases may get reduced by 70-79% by strong anti-epidemic measures. The enforcement of shutdown, lockdown, awareness, and improvement of medical and health care could also lead to about one-half transmission decrease and constructively abridge the duration of the 2019 n-CoV.

Abstract As recommended by the World Health Organization, standardization of prothrombin time assays involves conversion of prothrombin times into International Normalized Ratios (INR). We investigated the effect of two different methods (Nycomed's Thrombotest, and Instrumentation Laboratory's PT-fibrinogen) and three coagulation instruments (Schnitger & Gross, KC-10, and ACL) on calculations of INR. The INR plots showed considerable scatter of individual values around the regression lines when the two different methods were compared. Systematic differences in the outcome of INR calculation were related to the use of the different coagulation instruments. Prothrombin times obtained with the different instruments were linearly correlated. We used the bias of these lines to correct results for both the patients' samples and the reference samples. This correction yielded INR values from the different instruments that agreed well.

According to the World Health Organization, medulloepithelioma belongs to the embryonal neoplasm entity. It is a very rare, highly malignant tumor typically affecting infants and young children. Usually, the tumor arises in the eye or in the central nervous system; a peripheral location has been rarely reported without an established treatment. The recognition and separation of this neoplasm from other differential tumors are mandatory for better understanding of its biology and determination of optimal treatment. This paper reports a case of an ectopic intrapelvic medulloepithelioma with liver metastasis in a 3-year-old girl.

High Lead

Lead poisoning is becoming an epidemic in and around Kebbi State lately. Five samples were collected from mining Sites believed to have high lead concentration. Proton induced X-ray emission (PIXE) technique of 2.5MeV proton beam was used to characterize five geological samples collected from Maga, Danko Wasagu LG, Kebbi State, Nigeria to determined concentration of Lead (Pb) and other trace elements. Samples were irradiated and analyzed at Centre for Energy Research and Development, Ile-Ife, Osun State, Nigeria. The result obtained indicated that Pb is of commercial deposit in all the samples. Alongside, Si, S, K, Ca, Ti, Cr, Fe, Cu, Zn, Rb, Sr, Zr, Ba, P, V, Mn, Cl, Ce and Ni were determined. The result obtained for Pb concentration in samples A, B, C, D and E were 943ppm, 445ppm, 3279ppm, 212𝟶ppmand 529ppm respectively, which is above the world health recommendation of 400ppm for areas with children.Also element Si and Fe concentrations appear to be deposited in commercial quantities. These values imply that the miners and surrounding communities of Maga, Danko Wasagu LG, Kebbi State, Nigeria are at risk of learning disabilities, attention deficit disorders, behavioural problems, stunted growth, hearing problems, anaemia, kidney damage, stomach pain, mental retardation, coma, and death due to the high concentration of Pb.
