Serologic evidence of Toxoplasma gondii infection among cancer patients. A prospective study from Qassim region, Saudi Arabia.

To determine the frequency of antibody seropositivity of Toxoplasma gondii  infection in a cancer patient population. We also explored on association of Toxoplasma gondii seropositivity with selected variables. Methods: This is a prospective cross-sectional study conducted at  Prince Faisal bin Bandar cancer center, Qassim, Saudi Arabia, from November 2014 to  March 2015.

Prevalence of the prothrombin G20210A polymorphism in the Lebanese population: use of a reverse hybridization strip assay approach.

The factor II (prothrombin) G20210A gene polymorphism is the second most common SNP reported in VTE where it is associated with elevated plasma prothrombin levels and with a 3-fold increased risk. We studied the distribution of the G/G, G/A, and A/A genotypes of the Prothrombin G20210A gene mutation in the general Lebanese population using a novel technique in order to assess their prevalence, compare the results to previously reported data and to describe an available method that will permit easy and fast identification of the mutation. Prothrombin different genotypes were determined using the Cardiovascular Disease (CVD) StripAssay which is based on a Polymerase Chain Reaction-Reverse hybridization technique and DNA from 205 unrelated healthy donors from our HLA-bank was used.

MEFV gene mutations spectrum among Lebanese patients referred for Familial Mediterranean Fever work-up: experience of a major tertiary care center.

Familial Mediterranean Fever (FMF) is an autosomal recessive inflammatory disorder predominantly affecting people living in or originating from areas around the Mediterranean Sea, mainly Jews, Armenians, Turks, and Arabs. It is characterized by recurrent attacks of inflammation of serosal membranes and fever resulting in acute abdominal, chest, or joint pain. Over 50 MEditerranean FeVer (MEFV) mutations and polymorphisms have been identified in FMF patients.

Does Helicobacter pylori colonize the nasopharynx of children and contribute to their middle ear disease?

Objective: There is growing interest in studying the presence of HP in the upper aerodigestive tract. It was shown in several pilot studies that it colonizes the area, while other authors found no evidence of its presence there and a third group of authors believed that it had only a transient presence there. In this study we investigated a possible role for HP in middle ear disease in children.
