Population dynamics and tuberculosis: a cross sectional study of an overlooked disease in Saudi Arabia.

Background: International travel, migration and human population movements facilitate the spread of tuberculosis (TB).

Objective: To study the impact of poorly screened expatriates working in Saudi Arabia on the local incidence of TBs.

Patients And Methods: This cross sectional study was carried out in the Chest Disease Hospital, Taif.

Evaluation of biomedical research in Saudi Arabia.

Objective: To evaluate the quality and quantity of biomedical studies published in the Kingdom of Saudi Arabia (KSA) between 2010 and 2011.

Methods: This study was conducted on January 2013 at the Internal Medicine Department, Taif University, Taif, KSA. An online search was conducted on PubMed to collect the articles published from KSA using the country name (Saudi Arabia) as a keyword.

Comorbidity profile among patients with rheumatoid arthritis and the impact on prescriptions trend.

Comorbid conditions play a pivotal role in rheumatoid arthritis management and outcomes. We estimated the percentage of comorbid illness among rheumatoid arthritis patients and explored the relationship between this comorbidity and different prescriptions. A cross-sectional study of patients with rheumatoid arthritis in three centers in Saudi Arabia was carried out.

The temporal relationship of Raynaud's phenomenon and features of connective tissue disease in rheumatoid arthritis.

Objective: In a prospective cohort study we examined the relationship between Raynaud's phenomenon (RP) onset and other connective tissue disease (CTD) characteristics in rheumatoid arthritis (RA) to determine if RP is predictive of RA severity and associated with other CTD signs, and if late onset RP in RA has an effect on prognosis compared to other patients with RA.

Methods: Using a standardized assessment, data were collected on 328 subjects with RA [mean age 60.3 +/- 0.

Serum autoantibodies that bind citrullinated fibrinogen are frequently found in patients with rheumatoid arthritis.

Objective: Autoantibodies that bind citrullinated antigens are a sensitive and specific marker for rheumatoid arthritis (RA). While synthetic cyclic citrullinated peptides (CCP) are typically used to identify these antibodies, little is known about antibody reactivity to the predominant citrullinated protein found in the inflamed synovium, citrullinated fibrinogen (CitFib). We assessed the prevalence of anti-CitFib antibodies in patients with various rheumatic diseases.
