1.  Clinical significance of white gastric crypt openings observed via magnifying endoscopy 
AIM: To evaluate the relationship between Helicobacter pylori (H. pylori)-induced gastritis and white gastric mucosal crypt openings (COs) in the gastric corpus.
METHODS: A total of 175 consecutive patients (including 69 patients with gastric cancer) were enrolled in this study. We used magnifying endoscopy (ME) to observe the mucosa microsurface of the lesser and greater curvature of the gastric corpus (350 areas in all). We focused on areas with a round pit microstructure (primarily observed in non-atrophied areas) and evaluated the white openings of these gastric pits. We classified the whiteness of the COs as the “white-edged dark spot” type (consisting of a dark spot bordered by white); the “white” type (pure white with no dark spot); and the “dense white pit (DWP)” type (dense white, resembling a snowball). Gastritis was also histologically evaluated according to the updated Sydney System.
RESULTS: We detected round COs using ME in 246 of the 350 areas examined. The histological examination showed significantly more mononuclear cells and neutrophil infiltration in the “white” and “DWP” types than the “white-edged dark spot” type (P < 0.001). Furthermore, significantly high-grade inflammation and evidence of active H. pylori-induced gastritis was observed in the “DWP” type (P < 0.001). Significant differences were observed in the whiteness of COs between H. pylori-positive (n = 139) and negative (n = 36) patients (P < 0.001). The sensitivity and specificity of the “white” and “DWP” types for predicting H. pylori infection were 78.5% and 81.7%, respectively. Of the patients with gastric cancer, 22.5% (18/80) had “white-edged dark spots”, 51.3% (41/80) had “white” COs, and 26.3% (21/80) had “DWP”-type COs. “DWPs” were frequently observed among patients with undifferentiated gastric cancer [45.7% (16/35)].
CONCLUSION: CO whiteness detected via ME was associated with histological evidence of gastritis and helps to predict the severity of inflammation and H. pylori-induced activity.

2.  Sternoclavicular joint septic arthritis following paraspinal muscle abscess and septic lumbar spondylodiscitis with epidural abscess in a patient with diabetes: a case report 
Background
Septic arthritis of the sternoclavicular joint (SCJ) is extremely rare, and usually appears to result from hematogenous spread. Predisposing factors include immunocompromising diseases such as diabetes.
Case presentation
A 61-year-old man with poorly controlled diabetes mellitus presented to our emergency department with low back pain, high fever, and a painful mass over his left SCJ. He had received two epidural blocks over the past 2 weeks for severe back and leg pain secondary to lumbar disc herniation. He did not complain of weakness or sensory changes of his lower limbs, and his bladder and bowel function were normal. He had no history of shoulder injection, subclavian vein catheterization, intravenous drug abuse, or focal infection including tooth decay. CT showed an abscess of the left SCJ, with extension into the mediastinum and sternocleidomastoid muscle, and left paraspinal muscle swelling at the level of L2. MRI showed spondylodiscitis of L3-L4 with a contiguous extradural abscess. Staphylococcus aureus was isolated from cultures of aspirated pus from his SCJ, and from his urine and blood. The SCJ abscess was incised and drained, and appropriate intravenous antibiotic therapy was administered. Two weeks after admission, the purulent discharge from the left SCJ had completely stopped, and the wound showed improvement. He was transferred to another ward for treatment of the ongoing back pain.
Conclusion
Diabetic patients with S. aureus bacteremia may be at risk of severe musculoskeletal infections via hematogenous spread.
