Peri-articular Dextrose Prolotherapy: Investigating the Effect of Injection Site on Knee Osteoarthritis Pain: A Double-Blind, Randomized, Clinical Trial.

Background: Osteoarthritis (OA) is a chronic health condition that affects millions of people worldwide. It not only causes pain and physical limitations but also impacts mental health, sleep, work participation, and even mortality. Peri-articular dextrose prolotherapy has been shown to reduce knee osteoarthritis pain; however, the effect of injection sites on its effectiveness is not clear.

Association of Interleukin-10 Genotypes and Anticyclic Citrullinated Peptide Antibodies with Rheumatoid Arthritis.

According to recent evidence, there is an association between some genetic factors and rheumatoid arthritis (RA). The aim of this study was to determine whether genetic variations in the interleukin 10 (IL10) and anti-cyclic citrullinated peptide (Anti-CCP) antibody loci were linked to RA. In this hospital-based case-control study with 224 cases and 194 healthy individuals, we investigated the association of IL-10 genotypes and anti-CCP antibodies with RA.

Frequency of Growth Differentiation Factor 5 rs143383 and asporin D-repeat polymorphisms in patients with hand and knee osteoarthritis in Kurdistan province, Iran.

Aim: Osteoarthritis (OA) is the most common chronic joint disorder, resulting from the breakdown of joint cartilage. It occurs in the knees, hands, and hips, leading to pain, stiffness, inflammation, and swelling.

Methods: In this study, 100 hand and knee OA patients, meeting the American College of Rheumatology criteria were included in the case group, and 100 healthy individuals were allocated to the control group.

Health-care access and utilization among individuals with low back pain in Iran: a WHO-ILAR COPCORD study.

Background: Low back pain (LBP) is a major contributor to chronic pain and disability. The purpose of this study was to evaluate health-care access and utilization among patients with LBP in Iran. We also sought to study the pattern and characteristics of care-utilization behavior in these patients.

Risk factors of knee osteoarthritis: A case-control study.

Background And Objective: Knee osteoarthritis is one of the most common rheumatologic problems. To investigate risk factors related to the knee osteoarthritis a case-control study was performed using cases diagnosed in the Community Oriented Program for Control of Rheumatic Diseases (COPCORD) study, stage I.

Methods: Using data from the 2012 COPCORD study, stage-I that was conducted in Sanandaj, northwestern of Iran, we runned a case-control study in 2014-2015.

Validity and reliability of the Farsi version of the ECOS-16 questionnaire for females with osteoporosis.

The purpose of this study was to develop a Persian version of ECOS-16 Questionnaire and assess its reliability and validity. Two hundred and twenty women with postmenopausal osteoporosis were included in the study. Patients who were diagnosed as secondary osteoporosis by clinical and laboratory examinations were excluded.

Economic inequalities amongst women with osteoporosis-related fractures: an application of concentration index decomposition.

Considering the renewed emphasis on women's health, attention to the new aspects of their health, such as equity, among different groups is warranted. The aim of this study was to investigate the economic inequalities among women with osteoporosis-related bone fractures (ORBFs) in Sanandaj, Iran. In this cross-sectional study, convenient sampling was employed to recruit 220 women with osteoporosis referring to the only rheumatology clinic in Sanandaj (the center of Kurdistan province in Iran) from January to April 2013.

Epidemiology of rheumatic diseases in Iran from analysis of four COPCORD studies.

Aim: To calculate the epidemiology of Rheumatic Diseases in Iran.

Materials And Methods: The data of Tehran, Zahedan, Sanandaj (urban) and Tuyserkan (rural) stage Community Oriented Program for the Control of Rheumatic Diseases (COPCORD) studies were gathered. The data were adjusted to the population number of the studied areas to represent Iran.

Anti-cyclic citrullinated peptide (CCP) antibody in patients with wood-smoke-induced chronic obstructive pulmonary disease (COPD) without rheumatoid arthritis.

Citrullination, a post-translational modification of proteins, is increased in inflammatory processes and is known to occur in smokers. It can induce anti-cyclic citrullinated peptide (CCP) antibodies, the most specific serologic marker for rheumatoid arthritis. Thus far, the incidence of autoimmunity in patients with wood-smoke-induced chronic obstructive pulmonary disease (COPD) resulting in anti-CCP production has not been examined.

WHO-ILAR COPCORD study (stage 1, urban study) in Sanandaj, Iran.

This study aims to conduct an urban Community Oriented Program for Control Of Rheumatic Diseases (COPCORD) study in Sanandaj (Kurdistan, Iran). Sanandaj with a population of 311,446 (2006 census), Caucasian of Kurdish subgroup, was selected as the field. Sanandaj was divided into 100 clusters and subjects were randomly selected from them (50 subjects from each cluster).

Dyspepsia prevalence in general population aged over 20 in the west part of Iran.

Objective: To estimate the prevalence of dyspepsia in the general population aged over 20 in western Iran.

Methods: The cross-sectional study was conducted among the randomly selected general population over the age of 20 years in Sanandaj city. Iran, from April to December 2009.

Validity and reliability of the Persian versions of WOMAC Osteoarthritis Index and Lequesne Algofunctional Index.

The WOMAC Osteoarthritis Index and Lequesne Algofunctional Index have not been translated and validated for Iranian patients with osteoarthritis (OA) of the knee or hip. The aim of this study was to validate the Persian form of WOMAC OA Index and Lequesne Algofunctional Index and to assess their test-retest reliability and convergent validity. Forward/backward translations and consensus panels were conducted to obtain the Persian versions of WOMAC OA Index and Lequesne Algofunctional Index.
