Enterobiasis among Yemeni children: a cross-sectional study.

Enterobiasis is a highly infectious parasitic disease spreading worldwide including Yemen. Therefore, this study aimed to investigate the prevalence and risk factors of enterobiasis among Yemeni children in Dhamar governorate. A total of 402 children (aged 1-12 years) participated in this cross-sectional survey carried out at Thamar University Al-Wahdah Teaching Hospital (TUWTH), between 2018 and 2019.

Protocol biopsy of a transplanted kidney as a tool for monitoring adequacy of immunosuppressive therapy: 10 years of experience from a single transplant center.

Background: The aims of this prospective study were to determine the prevalence of clinically silent rejection changes and of nephrotoxicity of calcineurin inhibitors among repeated protocol biopsies of transplanted kidneys and to assess their impacts on chronic graft function and damage at the end of 1 year.

Methods: We performed 424 protocol biopsies among 158 patients over the first year after transplantation. We monitored parameters of graft function and progression of chronic changes among subjects with clinically silent rejection or toxicity for comparison with a control cohort showing normal histological findings.

Changes in bone mineral density and selected metabolic parameters over 24 months following renal transplantation.

Our aim was to evaluate changes in serum levels of selected bone metabolism indicators and bone density over 24 months following renal transplant. A partial objective was assessment of the effectiveness of prophylactic administration of vitamin D and calcium preparations to prevent progression of osteopathy after kidney transplantation. Forty patients after kidney transplantation were prophylactically given vitamins A and D (800 IU) and calcium (1000 mg) a day.
