Avascular necrosis (AVN), also known as osteonecrosis, is characterized by death of the osteocytes due to inadequate blood supply caused by various mechanisms. The hip is the most common affected joint followed by knee. Incidence of AVN in rheumatic diseases is variable and high corticosteroid (CS) therapy is a known major risk factor for development of AVN. Data on the AVN in Behcet disease (BD) are limited. The purpose of this study is to examine the clinical and treatment characteristics of BD patients with diagnosis of AVN. Retrospective medical records of 337 BD patients were reviewed. Nine BD patients with AVN were detected. The clinical data of these patients with AVN have been reviewed. All patients had MRI of the symptomatic joints compatible with AVN. All of the nine patients who were diagnosed with AVN were male. Median duration of BD was 7years. Median time between diagnosis of BD and detection of AVN was 3years (1-16years). Multiple joints were involved in seven patients. Six patients had bilateral knee AVN. Six patients had vascular BD. The median time interval between initial CS dose and AVN development was 24months (range=2-100). The median highest daily CS dose was 64mg/day (range=32-80) and median cumulative CS dose prior to AVN was 18g. All of patients had intravenous pulse steroids. CS treatment, smoking and vascular involvement may predispose to AVN in patients with BD. According to this cohort, AVN in BD frequently tended to be in the knee joint and bilateral.
Criteria Sets for Primary Sjogren's Syndrome Are Not Adequate for Those Presenting with Extraglandular Organ Involvements As Their Dominant Clinical Features

Patients with primary Sjogren's syndrome (pSS) may go undiagnosed or be misclassified due to the insidious nature and wide spectrum of the disease. The available several classification criteria emphasize glandular findings. We aimed to analyze the efficiency of various classification criteria sets in patients diagnosed on the clinical basis by expert opinion and to compare those pSS patients who fulfilled these criteria with those who did not. This is a multicenter study in which 834 patients from 22 university-based rheumatology clinics are included. Diagnosis of pSS was made on the clinical basis by the expert opinion. In this study, we only interviewed patients once and collected available data from the medical records. The European criteria, American-European Consensus Group (AECG) and American College of Rheumatology (ACR) Sjogren's criteria were applied. Majority of the patients were women (F/M was 20/1). The median duration from the first pSS-related symptom to diagnosis was significantly shorter in men (2.5 +/- 2.3 vs 4.3 +/- 5.9 years) (p = 0 < 0.016). When the European, AECG and ACR Sjogren's criteria were applied, 666 patients (79.9%) satisfied at least one of them. In total, 539 patients (64.4%) satisfied the European, 439 (52.6%) satisfied the AECG, and 359 (43%) satisfied the ACR criteria. Among the entire group, 250 patients (29.9%) satisfied all and 168 (20.1%) met none of the criteria. The rates of extraglandular organ involvements were not different between patients who met at least one of the criteria sets and those who met none. There is an urgent need for the modification of the pSS criteria sets to prevent exclusion of patients with extraglandular involvements as the dominant clinical features.
