Use of a Novel Artificial Intelligence System Leads to the Detection of Significantly Higher Number of Adenomas During Screening and Surveillance Colonoscopy: Results From a Large, Prospective, US Multicenter, Randomized Clinical Trial.

INTRODUCTION: Adenoma per colonoscopy (APC) has recently been proposed as a quality measure for colonoscopy. We evaluated the impact of a novel artificial intelligence (AI) system, compared with standard high-definition colonoscopy, for APC measurement. METHODS: This was a US-based, multicenter, prospective randomized trial examining a novel AI detection system (EW10-EC02) that enables a real-time colorectal polyp detection enabled with the colonoscope (CAD-EYE). Eligible average-risk subjects (45 years or older) undergoing screening or surveillance colonoscopy were randomized to undergo either CAD-EYE-assisted colonoscopy (CAC) or conventional colonoscopy (CC). Modified intention-to-treat analysis was performed for all patients who completed colonoscopy with the primary outcome of APC. Secondary outcomes included positive predictive value (total number of adenomas divided by total polyps removed) and adenoma detection rate. RESULTS: In modified intention-to-treat analysis, of 1,031 subjects (age: 59.1 ± 9.8 years; 49.9% male), 510 underwent CAC vs 523 underwent CC with no significant differences in age, gender, ethnicity, or colonoscopy indication between the 2 groups. CAC led to a significantly higher APC compared with CC: 0.99 ± 1.6 vs 0.85 ± 1.5, P = 0.02, incidence rate ratio 1.17 (1.03-1.33, P = 0.02) with no significant difference in the withdrawal time: 11.28 ± 4.59 minutes vs 10.8 ± 4.81 minutes; P = 0.11 between the 2 groups. Difference in positive predictive value of a polyp being an adenoma among CAC and CC was less than 10% threshold established: 48.6% vs 54%, 95% CI -9.56% to -1.48%. There were no significant differences in adenoma detection rate (46.9% vs 42.8%), advanced adenoma (6.5% vs 6.3%), sessile serrated lesion detection rate (12.9% vs 10.1%), and polyp detection rate (63.9% vs 59.3%) between the 2 groups. There was a higher polyp per colonoscopy with CAC compared with CC: 1.68 ± 2.1 vs 1.33 ± 1.8 (incidence rate ratio 1.27; 1.15-1.4; P < 0.01). DISCUSSION: Use of a novel AI detection system showed to a significantly higher number of adenomas per colonoscopy compared with conventional high-definition colonoscopy without any increase in colonoscopy withdrawal time, thus supporting the use of AI-assisted colonoscopy to improve colonoscopy quality ( ClinicalTrials.gov NCT04979962).

Coinfection of Streptococcus agalactiae and Tuberculous Osteomyelitis of Tibia Mimicking Brodie's Abscess in an Immunocompetent Adult: A Case Report.

Introduction: Coinfection of tuberculous osteomyelitis with Streptococcus agalactiae has not been reported in an immunocompetent adult so far. The slow progress of tuberculous osteomyelitis, due to lack of significant elevations in the laboratory values and changes in the radiographic appearance, often leads to confusion with brodie's abscess. These two clinical conditions often lead to delay in diagnosis and progressive bone destruction. The aim of this report was to highlight recognizing the possibility of coinfections in tuberculous osteomyelitis and early treatment targeting both organisms simultaneously. Case Report: We report a case of a 24-year-old male patient from Kerala, India presented with pain and swelling over distal leg for 2 weeks along with mild fever for 1 month. Imaging showed a brodie's abscess over distal tibia. Pus culture isolated S. Agalactiae. Bone biopsy reported as necrotizing granulomatous lesion. Computed tomography thorax was suggestive of necrotic tuberculous mediastinal and hilar lymphadenopathy. Based on histopathology, microbiology, and radiological findings, coinfection of tuberculous osteomyelitis and bacterial infection was confirmed and antitubercular therapy was started, along with antibiotics for S. agalactiae. Conclusion: Tuberculous osteomyelitis mimicking brodie's abscess is very rare. It is important to consider coinfection in osteomyelitis and it is essential to do tuberculosis-polymerase chain reaction and histopathological examination, along with bacterial and fungal culture of pus in subacute osteomyelitis for the early diagnosis and treatment.
