Gestational trophoblastic tumor (GTT) most commonly follows a molar pregnancy. In fact, it can occur following gestational events such as induced or spontaneous abortion, ectopic pregnancy, and term pregnancy. In this study, we present the case of a patient with ectopic pregnancy who was treated with a single dose of methotrexate (MTX). The maximum titer of beta subunit of human chorionic gonad...

Introduction: Transitional cell carcinomas (TCC) of the upper urinary tract constitute only 7% of urothelial carcinomas. The majority of upper urinary tract TCC arises from the renal pelvis, followed by the ureter. The majority of the patients are presented with microscopic or macroscopic haematuria, flank pain, or symptoms due to metastasis; however, it can be asymptomatic in 10-15%. Case pre...

Thalassemia syndrome has diverse clinical presentations and a global spread that has far exceeded the classical Mediterranean basin where the mutations arose. The mutations that give rise to either alpha or beta thalassemia are numerous, resulting in a wide spectrum of clinical severity ranging from carrier state to life-threatening, inherited hemolytic anemia that requires regular blood transf...

Beta-thalassemia is one of the most prevalent autosomal disorders in the world. Mutations in the HBB gene underlie deficiencies in hemoglobin production, which can interfere with oxygen delivery resulting in wide range of disease severity. Although >535 mutations have been characterized in the HBB gene, beta-thalassemia is broadly classified into three groups, based on clinical severity: beta-t...

Since it was first claimed in 1995 that human chorionic gonadotropin (hCG) inhibits HIV-associated Kaposi's sarcoma (KS), focus has been lost on establishing a credible hypothesis to explain a novel action ascribed to hCG, which is, after all, a pregnancy hormone. After 7 years, no real progress has been made, and there remains no consensus as to which component of hCG preparations is responsib...

Human chorionic gonadotropin (hCG) is a glycoprotein hormone composed of two dissimilar subunits, alpha and beta. Nicks or missing peptide linkages have been found in the beta 44-52 region of the beta-subunit of hCG, whether from pregnancy or trophoblast disease. This article reviews recent reports about the location of nicks in hCG, their origin and occurrence, their effects on the steroidogen...

IFN-beta treatment is emerging as a potentially effective form of therapy in various immune-mediated conditions. The present review addresses the possible role of IFN-beta in immune-mediated diseases such as multiple sclerosis and rheumatoid arthritis. Several placebo-controlled trials are discussed, as are the available immunological data that are relevant to this field. Review of these data p...
