Recently, the unique nucleic acid closely related to the herpes-like sequences has been found in acquired immunodeficiency syndrome (AIDS)-associated Kaposi's sarcoma (KS). We have confirmed the presence of herpes-like DNA sequences in six cases of AIDS-associated KS and three of the nine cases of African-endemic KS in adults, but not in eight cases of KS in children from the same area. These s...

Klinefelter syndrome (KS) is a hypergonadotropic hypogonadism characterized by a 47, XXY karyotype. The risk of testicular cancer in KS is of interest in relation to theories about testicular cancer etiology generally; nevertheless it seems to be low. We evaluated the need for imaging and serum tumor markers for testicular cancer screening in KS. Participants were 40 consecutive KS patients, en...

In this study, we aimed to evaluate the incidence, features and outcome of post transplant KS among Iranian recipients of living kidney allograft. We studied 2211 kidney allograft recipients who underwent living renal transplantation at our center between January 1984 and August 2007. All patients in our study received cyclosporine based immunosuppressive agents. The diagnosis of KS was confirm...

This overview is intended to provide an “ atlas ” of what is known about approximations of the cone of positive polynomials (on a semialgebraic set KS) by various preorderings (or the corresponding module versions). These approximations depend on the description S of KS, the dimension of the semi-algebraic set KS, intrinsic geometric properties of KS (e.g. compact or unbounded), and special pro...

BACKGROUND Kaposi Sarcoma (KS) is a malignancy of endothelial skin cells with multifocal localization on the skin, lymph nodes and visceral organs. Although all clinical variants are associated with HHV-8 infection, specific differences in the clinical onset and in the natural history of AIDS-KS and Classic-KS have been described. The present randomised prospective-observational study aimed to ...

Kaposi’s sarcoma (KS) was first described by Hungarian dermatologist Moritz Kaposi in 1872. Kaposi first described the lesions as “idiopathic, multiple pigmented sarcoma of the skin”. Kaposi’s sarcoma is a spindle cell tumor of endothelial origin. It is commonly associated with the endothelial lining of blood vessels. In the early 1980’s, KS was commonly associated with the AIDS epidemic. Four ...

Kaposi's sarcoma (KS) is the most common tumor associated with HIV-1 infection. Here, we report the expression, regulation, and biological effect of interleukin (IL)-8 in KS. AIDS-KS cell lines expressed higher levels of IL-8 than either human umbilical vein endothelial cells (HUVECs), human aortic smooth muscle (AoSM) cells or fibroblast cells (T1). The inflammatory cytokine IL-1beta up-regula...

Kartagener's syndrome (KS) is characterised by bronchiectasis, paranasal sinusitis and situs inversus totalis (SIT). Association of diffuse bronchiolitis (DB) with KS has been documented from Japan only. Fourteen patients with SIT were seen in one unit over 7 years. All patients underwent a similar work up which included high resolution computed-tomography (HRCT) of thorax and CT-paranasal sinu...

AIDS-related Kaposi's sarcoma (AIDS-KS), which is the most prevalent AIDS related cancer, arises in a unique environment characterized by profound immunosuppression in conjunction with sustained immunostimulation. Persistent inflammation and the accompanying increased production of reactive species can promote carcinogenesis by numerous routes including sustained cell proliferation, initiation ...
