Objective: To evaluate the clinical associations of antineutrophil cytoplasmic antibodies (ANCA) in patients with early rheumatoid arthritis (RA), as well as the possible predictive role of ANCA. We also assessed the overlap of ANCA with other specific serologic markers of RA.
Methods: Eighty-two RA patients with symptoms for < or = 12 months were studied for the presence of ANCA by immunofluorescence and specific enzyme immunoassays. ANCA were determined and clinical, radiographic, and laboratory data were collected at study entry and later at 12, 36, 60, and 84 months.
Results: In 2 patients, the first serum samples (obtained at study entry) were no longer available for the determination of ANCA. Perinuclear ANCA (pANCA) were found in 40 patients (50%), and atypical cytoplasmic ANCA were found in 3 patients (4%) at study entry. Perinuclear ANCA-positive patients were significantly more frequently positive for rheumatoid factor (78%) than were ANCA-negative patients (54%) (P = 0.0297). Fifty-five percent of pANCA-positive patients and 22% of ANCA-negative patients were positive for antiperinuclear factor (P = 0.0044). Similarly, pANCA-positive patients had antikeratin antibodies more frequently than did ANCA-negative patients (35% versus 20%). During a 7-year followup, the progress of radiographic joint destruction, assessed with Larsen scores, was significantly more rapid in patients who were pANCA positive at study entry than in those who were ANCA negative (P = 0.0015). Also, the mean titer of pANCA at study entry was significantly higher in those patients who subsequently had advanced radiographic joint destruction at 60 and 84 months. The association of pANCA with rapid radiographic destruction in patients with early RA was further corroborated by a logistic regression analysis that selected pANCA positivity as an independent and statistically significant predictor of rapid radiographic joint destruction.
Conclusion: In patients with early RA, pANCA are associated with specific serologic markers of RA and predict rapid radiographic joint destruction.

Aim: The Transorbital and supraorbital minimally invasive approaches have been defined to reach intraorbital structures, adjacent sinuses, skull base, and other intracranial targets in this region. These approaches reduce the possible cosmetic and brain retraction-related morbidities caused by traditional transcranial approaches. Although these pathways are being studied endoscopically, a stereotactic approach has not been defined.

Purpose: This study aims to explore the underlying causes, diagnostic strategies, and treatment approaches of trauma-induced invasive syndrome (KPIS) through a rare case report. By highlighting the role of trauma as a potential trigger for KPIS, particularly in high-risk populations such as individuals with diabetes, this study seeks to provide valuable insights for improving clinical outcomes and promoting public health awareness.
Background: invasive syndrome is a multi-organ infectious disease commonly associated with complications such as liver abscess, lung abscess, endophthalmitis, and purulent meningitis, with high mortality and disability rates.

Abstract: Recent clinical trials on slowing dementia progression have led to renewed focus on finding safer, more effective treatments. One approach to identify plausible candidates is to assess whether existing medications for other conditions may affect dementia risk. We conducted a systematic review to identify studies adopting a data-driven approach to investigate the association between a wide range of prescribed medications and dementia risk.
