PRP as a modulator of inflammation in FLS of RA patients by regulation of galectins and TGF-β1.

Unlabelled: An autoimmune and inflammatory condition known as rheumatoid arthritis is characterized by joint inflammation and an aggressive fibroblast-like synoviocytes. (FLS) One of the most significant immunological regulators are the galectins. Platelet-rich plasma are probably effective in immunomodulation.

Pernicious Anemia Following COVID-19 Vaccination: A Report of Two Cases.

Since December 2019 and the global epidemic of COVID-19 different countries have focused on vaccines, and one of the inactivated produced vaccines was the Sinopharm COVID-19 vaccine. Some side effects of this vaccine were reported previously, including pain at the vaccination site, fatigue, lethargy, headache, and tenderness, which were more prevalent among individuals <49 years old. Herein, we reported two patients aged 45 and 51 years old.

COVID-19 infection: a possible induction factor for development of autoimmune diseases?

Following the global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the importance of investigation of the pathogenesis and immunological characteristics of COVID-19 became quite clear. Currently, there are reports indicating that COVID-19 is able to induce autoimmune responses. Abnormal immune reactions are a cornerstone in the pathogenicity of both conditions.

Effects of crystalline penicillin G sodium on human T-cells differentiation.

Background: Although antibiotics are well-known for their anti-bacterial effects, their inaugurated immunomodulatory roles in chronic inflammatory diseases have not elucidated yet. Anecdotal reports support the beneficial effects of parenteral penicillin in arthritis suggesting an immunomodulatory other than antibacterial effects for penicillin. The present study was designed to address the possible effects of penicillin G sodium (PCN-G) on different T-helper cells differentiation.

Penicillin in oral aphthosis, new insight for an old drug: A randomized, double-blind, controlled clinical trial.

Background: Oral aphthosis is a painful ulceration of mucus membranes characterized by round or oval lesions with central necrosis and erythematous haloes. Due to unknown etiology, treatment is highly controversial and based mainly on individual experience. The aim of this study was to investigate the safety and efficacy of topical penicillin 6.

Frequency of sacroiliitis among patients with low back pain.

Introduction: Sacroiliitis is one of the important symptoms in patients attending infectious diseases and rheumatology clinics. Some patients with sacroiliitis are asymptomatic, and some have unspecific symptoms. The aim of this study was to determine the frequency of sacroiliitis causes among patients attending Shahid Sadoughi's infectious disease and rheumatology clinics.

Felty's Syndrome, Insights and Updates.

Felty's syndrome (FS) is characterized by the triad of seropositive rheumatoid arthritis (RA) with destructive joint involvement, splenomegaly and neutropenia. Current data shows that 1-3 % of RA patients are complicated with FS with an estimated prevalence of 10 per 100,000 populations. The complete triad is not an absolute requirement, but persistent neutropenia with an absolute neutrophil count (ANC) generally less than 1500/mm3 is necessary for establishing the diagnosis.

Thromboangiitis obliterans with cryoglobulinemia.

Thromboangiitis obliterans (TAO), or Buerger's disease, is a vascular occlusive disease associated with cigarette smoking. It typically affects medium sized vessels of extremities. Basic pathology of TAO is described to be endothelial activation with highly inflammatory intraluminal thrombosis preserving internal elastic membrane.

Systemic aspects of soft tissue rheumatic disorders (STRDs).

Objective: To determine the markers of systemic inflammation in soft tissue rheumatic disorders (STRDs).

Study Design: Case series.

Place And Duration Of Study: Rheumatology Clinic, Yazd, Iran, from November 2010 to December 2011.

Visual problem and low back pain as initial manifestation of multiple myeloma complicating pre-existing systemic sclerosis.

Some connective tissue diseases are associated with an increased risk of developing neoplastic disorders. Association of rheumatoid arthritis and systemic lupus erythematosus with lymphoma, and of dermatomyositis with different malignancies including ovarian and lung cancer has been reported in the literature. Here, we describe a 58 years old man with systemic sclerosis (SSc) for 15 years who developed severe lumbar pain when he was admitted for intravenous infusion of prostaglandin E1 for his fingertip ulcers.

Digital panoramic radiography as a useful tool for detection of bone loss: a comparative study.

This study was aimed to investigate the use of panoramic radiography in patients with low bone mineral density (BMD) in order to diagnose and prevent osteoporotic fractures. Panoramic radiographs of 60 patients  (20 men and 40 women) aged from 40 to 70 years with cortical thicknesses of less than 3 mm in the mandibular angle were selected from patients referred to a dentomaxillofacial radiology clinic and were then examined for mandibular cortical angles. These were measured using Computed Radiography (CR) software.

Management of immune cytopenias in patients with systemic lupus erythematosus - Old and new.

There are various immune cytopenias associated with systemic lupus erythematosus (SLE). The most common one is anemia; however, there are different etiologies for the anemia caused by SLE. Anemia could be due to chronic disease, secondary to renal insufficiency, blood loss, drug induced or autoimmune hemolysis.

Idiopathic granulomatous mastitis, erythema nodosum and bilateral ankle arthritis in an Iranian woman.

Here we report a case of idiopathic granulomatous mastitis (IGM) associated with erythema nodosum (EN) and ankle arthritis. The skin, joint and mammary symptoms improved with corticosteroid. Coincidence of granulomatous mastitis, EN and arthritis is a rare feature.

Rheumatological findings in candidates for valvular heart surgery.

Background and Objectives. Valvular heart diseases are among the frequent causes of cardiac surgery. Some patients have a well-known rheumatic condition.

Cardiac manifestations of rheumatological conditions: a narrative review.

Cardiovascular diseases are common in systemic rheumatologic diseases. They can be presented at the time of diagnosis or after diagnosis. The cardiac involvements can be the first presentation of rheumatologic conditions.

The effect of garlic tablet on pro-inflammatory cytokines in postmenopausal osteoporotic women: a randomized controlled clinical trial.

Introduction: Menopause is one of the important causes of osteoporosis which results from estrogen deficiency. In addition, some clinical and experimental evidence indicates that there is an association between increasing pro-inflammatory cytokine activity and postmenopausal bone loss. The purpose of this study was to determine the effect of garlic tablet on pro-inflammatory cytokines in postmenopausal osteoporotic women.

Dermatomyositis sine myositis with membranoproliferative glomerulonephritis.

Dermatomyositis (DM) is an autoimmune disease that is characterized by involvement of proximal musculature and skin. We report a 52-year-old woman with a 6-year history of dermatomyositis sine myositis, who developed lower extremity edema and proteinuria. Pathological examination of renal biopsy showed membranoproliferative glomerulonephritis.

Bedtime single-dose prednisolone in clinically stable rheumatoid arthritis patients.

Introduction. Sign and symptoms of rheumatoid arthritis have circadian rhythms and are more prominent in the morning. Timing of glucocorticoid administration may be important with respect to the natural secretion of endogenous glucocorticoids.

Ischemic toes after venous thromboembolism: a difficult differential diagnosis with good response to combination therapy-a case report.

The obliteration of the arterial vascular system of toes is considered as a potentially catastrophic event in clinical practices. In most instances, the cessation of arterial blood flow heralds a serious underlying pathology. A definite classification of some cases is somehow difficult and subject to diagnostic challenges.

Occupational hazards to dental staff.

Dental professionals are predisposed to a number of occupational hazards. These include exposure to infections (including Human Immunodeficiency Virus and viral hepatitis); percutaneous exposure incidents, dental materials, radiation, and noise; musculoskeletal disorders; psychological problems and dermatitis; respiratory disorders; and eye insults. Percutaneous exposure incidents remain a main concern, as exposure to serious infectious agents is a virtual risk.
