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.

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.

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.

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.

Abstract Background The World Health Organization recommends exclusive breastfeeding for the first 6 months and continued breastfeeding up to 24 months and beyond. Breastfeeding is beneficial for infant growth, development, and survival. Evidence on the association between breastfeeding duration and growth is not conclusive. The aim of the present study was to establish the association between breastfeeding duration and growth among infants and young children. MethodsThe study is based on data from the 2018 Zambia Demographic and Health Survey (ZDHS). The primary outcome for the study was height-for-age Z-score (HAZ). Association between HAZ and breastfeeding duration was assessed by using regression analysis. ResultsThe overall mean ± SD for HAZ was -1.24 ± 1.46 and the median (interquartile range) breastfeeding duration was 9 (4-14 months). After controlling for potential confounders, breastfeeding duration was inversely associated with HAZ (β=-0.07, p<0.001) and WHZ (β=-0.04, p<0.001). Path analysis demonstrated that the effect of breastfeeding duration is independent of child’s birth weight and maternal perceived birth size. Other determinants of HAZ were child’s weight and sex, while WHZ was predicted by maternal age, diarrhea episode and child’s birth weight. ConclusionBreastfeeding duration is negatively associated with both HAZ and WHZ among Zambian children. However, the magnitudes of the association are quite small to be of clinical significance. Thus, breastfeeding should continue to be promoted, protected and supported from birth up to two years and beyond.

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.

Currently, according to the World Health Organization, about 20% of the world's population takes non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs are lipophilic substances that easily penetrate the blood-brain barrier and can cause side effects from the central nervous system. Neurotoxicity (headache, dizziness, insomnia, depression, depersonalization, psychosis, and tremor occur during the treatment with indomethacin; visual impairment, drowsiness - during the treatment with meloxicam; hearing loss - when taking salicylates) ranks second after gastrotoxicity. The article describes the mechanisms of neurotoxicity that occur when taking NSAIDs.
