The lack of hygienic practices, treated water, and health education due to the high level of poverty are the major factors associated with the prevalence of amoebiasis disease in Yemen. Consequently, this study aimed to find the prevalence of <em>E.</em> <em>histolytica </em>among children attending the healthcare centres of Amran Governorate, Yemen. A total of 271 specimens were chosen from infected children aged between 1-14 years attending healthcare centres in the period between January to June 2019. The collected specimens were examined by direct microscopical examination, saline sedimentation, and formalin-ether concentration. The results showed that 166 (61.25%) specimens were positive for <em>E.</em> <em>histolytica</em> while 105 (38.75%) specimens were negative. The highest prevalence of amoebiasis was 85 (62.04%) recorded among children from rural areas compared to 81(60.45%) children from urban areas. In the urban area, it was found that the overall rates of infection between males (57.14%) and females (58.21%) were similar. Also, a higher prevalence rate (81.25%) was recorded among males aged between 8 to 14 years. The number of infected age groups was equal in both gender in the rural area. The results based on gender revealed 53.1% of infected children were male and 46.99% were female. The associated factors with the highest prevalence of <em>E. histolytica</em> infection were recorded among parents of children with the illiterate status of education, children drinking water from the uncovered water source, and the children who did not wash hands after defecation. Different strategies that include health education programs, treatment of the drinking water, personal hygienic practices, and increased community awareness about infection transmission warrant to enhance the control of intestinal parasitism and morbidity caused by <em>E. histolytica</em> parasite.</p> 2020-07-31T00:00:00+00:00 Copyright (c) 2020 PSM Biological Research Nutritional Rickets in Three Years Old Boy: A Case Report 2020-09-09T23:55:23+00:00 Imran Wali Khan Sardar Azhar Mehmood Shabir Ahmed Ikram Khan <p>Rickets is a severe vitamin D deficient disorder mostly of developing countries due to the least exposure to sunlight and poor nutrition. Rickets causes inappropriate absorption of phosphorus and calcium. It retards growth; alters phosphorus, calcium, and vitamin D metabolism and causes the bony manifestation of the patient. We describe the clinical course severe vitamin D deficiency in a boy of three years with cold and dry cough sweats on the forehead at night and can’t walk and stand. Multi-disciplinary physical, laboratory, and clinical analysis; the child was diagnosed as nutritional rickets with fever and respiratory infection. Treatment with proper exposure to sunlight vitamin supplements and adequate nutrition is directed. Rickets is a worldwide public health problem that arises due to vitamin D and calcium deficiency found more in children than adults. Early diagnosis of rickets in humans provides the optimal and proper treatment for saving a patient’s life.</p> 2020-07-31T00:00:00+00:00 Copyright (c) 2020 PSM Biological Research
