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.

Kikuchi fujimoto disease.

In order to determine the clinical significance of Kikuchi Fujimoto Disease (histiocytic necrotizing lymhadenitis) and to review the literature available on this condition, we selected the Medicine research papers in English language published between the years 1972 to 2011.Kikuchi Fujimoto Disease (KFD) is an uncommon, cosmopolitan, benign and self-limiting condition with higher Japanese and Asian prevalence. Most of the sufferers of KFD are young people who seek treatment because of having acute tender cervical lymphadenopathy, low grade fever and night sweats.

The prescription of allopurinol in a tertiary care centre: appropriate indications and dose adjustment.

Objective: To determine the appropriateness (both indications and adequate dosage regimen via creatinine clearance estimation) of allopurinol by physicians of different specialties in a tertiary care centre.

Patients And Methods: In this cross sectional study computerized clinical records of 156 adult patients who were prescribed allopurinol from 12th November to 11th December, 2011 were retrieved from Al Hada Hospital Taif Saudi Arabia. Main outcome variables were approprsiate indications of allopurinol, prescribing physician's specialty, and dosage of allopurinol.

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.

Refractory polyarteritis nodosa successfully treated with infliximab.

We describe a woman with severe polyarteritis nodosa (PAN) with visceral involvement unresponsive to multiple immunosuppressive drugs. Infliximab treatment was very effective in this case. Infliximab may potentially be used as an alternative agent for the treatment of patients with PAN refractory to conventional therapy.
