Objective: This work surveyed the level of knowledge about the “spit don’t rinse” brushing technique and studied the influencing factors among dental patients in Vajira Hospital. Methods: A cross-sectional survey was conducted on 385 dental patients in Vajira Hospital from September to November 2021. The level of knowledge of the “spit don’t rinse” brushing technique and the influencing factors were collected using an online questionnaire created by the researchers. Frequency, percentage, mean, and standard deviation were calculated, and the level of knowledge was compared among the different groups by chi-square test. Multiple logistic regression analysis was used to analyze the relationship between the influencing factors and level of knowledge. Results: The overall mean knowledge score was 5.3 ± 2.73. Approximately 76.6% of the dental patients had a low level of knowledge about the “spit don’t rinse” brushing technique. Comparison revealed that sex, age, education, occupation, and experience of learning had a statistically significant influence on the level of knowledge. Multiple logistic regression analysis revealed that the following two factors were correlated with moderate/high level of knowledge about the “spit don’t rinse” brushing technique: higher education (adjusted OR = 8.87, 95%CI: 1.66–46.40, p-value = 0.011) and experience of learning (adjusted OR = 3.56, 95%CI: 1.22–10.37, p-value = 0.020). Conclusion: The dental patients treated in Vajira Hospital do not understand and follow the correct procedures of the “spit don’t rinse” brushing technique. Dental practitioners should effectively provide knowledge on this practice to prevent dental caries, promote oral health, and reduce the prevalence of dental caries.

Objective: To determine mammographic and ultrasonographic features of male breast cancer. Methods: A retrospective study was conducted on consecutive men who underwent mammography and ultrasonography at the Diagnostic Breast Cancer Center in Vajira Hospital from January 1, 2010 to December 31, 2019. Clinical information, mammographic and ultrasonographic findings, method of tissue diagnosis, and pathological results were retrospectively reviewed. Then, the incidence of male breast cancer was analyzed. Results: A total of 41 men underwent mammography in the institution during the study period with a median age of 68 (interquartile range, 58–76) years. Three patients were diagnosed with breast cancer (7.3%), with circumscribed high-density mass being the most common mammographic finding in the cancer group and gynecomastia in the benign group. Ultrasonographic finding in the cancer group showed a solid hypoechoic mass in 1 patient and complex mass with solid-cystic components in 2 patients. Tissue diagnosis and pathological results were observed in 6 patients. Breast cancer was found in 3 patients (invasive ductal carcinoma in 2 and intraductal papillary carcinoma in 1 patient) and benign pathology of gynecomastia in 3 patients. The incidence of male breast cancer in this study was 7.3%. Conclusion : Male breast cancer commonly presents as a high-density mass with circumscribed margin in a subareolar location on mammography and as a solid hypoechoic mass or a complex mass with solid-cystic components on ultrasonography. As a result, a circumscribed mass on mammography with cystic components on ultrasound in a male patient should be suspected of malignancy.

Objective: In this study, we evaluated the results of our interrupted anastomosis operations. Methods: A retrospective review was conducted on consecutive operations for interrupted anastomosis wrist AVF performed by staff surgeons from January 2005 to December 2018. Results: Among the 50 cases, 45 (90%) were successful. The primary failure rate was 10%, and the maturation time required for the fistula to develop was 8.14 weeks. Patency rates were 79%, 70%, and 62% at the end of the 1st, 3rd, and 5th years, respectively. Anastomotic aneurysm was the second most common complication. Conclusion: Interrupted anastomosis increases the opportunity for the construction of a successful wrist AVF and is a reliable, safe technique with a high patency rate.
