objectives:prenatal infections are one of the fundamental causes of early puerperal complications in mothers and neonates. these infections are mostly due to colonized organisms in pregnant woman's genitor-urinary system. the aim of this study was to determine the incidence of streptococcus group b (gbs) colonization in parturient women and the rate of pathogen transmission to the newborn....

Human Immunodeficiency Virus type 1 (HIV-1) is a retrovirus that targets cells from the immune system such as the CD4 T lymphocytes, the macrophages and the dendritic cells (DCs). Although these host cells possess various defense mechanisms to fight this infection, HIV-1 has evolved multiple strategies to counteract them. For the past ten years, researchers have been focused on the identificati...

An asymptomatic, homosexual, white man was found to have an abnormal chest x ray. A presumptive diagnosis of sarcoidosis was made, but pulmonary function tests and a transbronchial biopsy were normal. He then remained asymptomatic for 10 years until he developed a progressive spastic paraparesis. At this point, antibodies to human T cell lymphotropic virus type 1 (HTLV-1) were identified in the...

Emerging evidence suggests that early events in human immunodeficiency virus type 1 (HIV-1) infection may play a critical role in determining disease progression. Although there is limited evidence on which to base medical decisions, the diagnosis and treatment of acute HIV-1 infection may have virologic, immunologic, and clinical benefits. In addition, rapid diagnosis of infection may prevent ...

background and objective: this study was undertaken to assess the ability of standard urinalysis (ua) and hemocytometer white blood cell (wbc) counts for the diagnosis of urinary tract infection (uti) in patients with urinary symptoms. materials and methods: a total of 600 patients with symptoms of urinary tract infection were enrolled in this prospective study. standard ua, hemocytometer wbc c...
