Objective: To categorize multiparametric MRI features of Bacillus Calmette–Guérin (BCG)-related granulomatous prostatitis (GP) and discover potential manifestations for its differential diagnosis from prostate cancer. Materials and Methods: The cases of BCG-related GP in 24 male (mean age ± standard deviation, 66.0 ± 9.4 years; range, 50–88 years) pathologically confirmed between January 2011 and April 2019 were retrospectively reviewed. All patients underwent intravesical BCG therapy followed by a MRI scan. Additional follow-up MRI scans, including diffusion-weighted imaging (DWI), were performed in 19 patients. The BCG-related GP cases were categorized into three: A, B, or C. The lesions with diffusion restriction and homogeneous enhancement were classified as type A. The lesions with diffusion restriction and a poorly enhancing component were classified as type B. A low signal intensity on high b-value DWI (b = 1000 s/mm2 ) was considered characteristic of type C. Two radiologists independently interpreted the MRI scans before making a consensus about the types. Results: The median lesion size was 22 mm with the interquartile range (IQR) of 18–26 mm as measured using the initial MRI scans. The lesion types were A, B, and C in 7, 15, and 2 patients, respectively. Cohen’s kappa value for the inter-reader agreement for the interpretation of the lesion types was 0.837. On the last follow-up MRI scans of 19 patients, the size decreased (median, 5.8 mm; IQR, 3.4–8.5 mm), and the type changed from A or B to C in 11 patients. The lesions resolved in four patients. In five patients who underwent prostatectomy, caseous necrosis on histopathology matched with the non-enhancing components of type B lesions and the entire type C lesions. Conclusion BCG-related GP demonstrated three imaging patterns on multiparametric MRI. Contrast-enhanced T1-weighted imaging and DWI may play a role in its differential diagnosis from prostate cancer.

PURPOSE: To examine the effects of auricular acupressure on symptoms of patients with allergic rhinitis and their quality of life. METHODS: A quasi experimental was used with a nonequivalent control group pretest-posttest method involving 56 adult outpatients who were seen in the Allergy & Asthma clinic at a tertiary referral hospital in Seoul, Korea. The experimental group (n=28) received 2 weeks of auricular acupressure to the Shenmen, wind stream, endocrine, adrenal, and lung acupuncture points; no acupressure was provided to the control group (n=28). Outcome measures included Total Nasal Symptom Score used to assess nasal symptoms, and the Rhinoconjunctivitis Quality of Life Questionnaire to assess the quality of life. Repeated measure ANOVA and independent t-test were used to calculate statistical significance. RESULTS: The experimental group showed significant improvements in terms of allergic rhinitis symptoms (p < .001) and on the Rhinoconjunctivitis Quality of Life Questionnaire (p < .001) compared to the control group. CONCLUSION: Finding in this study indicate that auricular acupressure can be used as a nursing intervention to alleviate nasal symptoms and improve rhinoconjuctivitis quality of life in allergic rhinitis patients.
