Comparison of Mammography, Sonography, Fine-Needle Aspiration Cytology, and Excision Biopsy for the Diagnosis of Breast Lesions

Background and Objective: Problem of invasive tests in breast lesion diagnosis can be addressed by comparing noninvasive tests with final Histopathological diagnosis obtained a?er excision biopsy. Present study was carried out to study diagnos?c u?lity of mammography, sonography, FNAC compared to excision biopsy for diagnosis of breast lesions Methods: Prospec?ve Observa?onal study was carried out among 81 women with Breast related symptoms. Digital Mammography Machine, ACUSON S3000TM Ultrasound System; FNAC and surgery for excision Biopsy were used. Sensi?vity, Specificity, Accuracy, Posi?ve and Nega?ve Predic?ve values were measured and p<0.05 was considered as sta?s?cally significant. Results: Sonography and FNAC composite have sensi?vity, specificity, accuracy, posi?ve and nega?ve predic?ve values 100.00%, 81.40%, 90.12%, 82.61% and 100.00% respec?vely. Mammography+FNAC (97.3%) is not as sensi?ve as Sonography+FNAC (100%), Sonography combined with FNAC is equally sensi?ve to excision biopsy (100%) and therefore can be used for screening purpose. Conclusion: Contrary to present guidelines which consider Mammography as most important screening tool for Breast Cancer, combina?on of Sonography and FNAC can be considered equally reliable.

Proficiency of Residents and Fellows in Performing Neonatal Intubation.

Objectives: To determine success rate and time taken for intubation by pediatric residents/ fellows. Methods: Prospective observational study among neonates requiring endotracheal intubation. Results: 212 attempts and 118 successful intubations were recorded in 153 videos. An average of 1.93 attempts per successful intubation was observed. Success rate at first attempt and mean time taken by first year, second year, third year residents and fellows were 26% and 51.9; 79% and 39.8; 69% and 40.1; and 67% and 31.5 seconds, respectively. Complications were noted in 77 (36%) attempts. 44 (21%) intubations were performed within 30 seconds. Increase in complications was noted with increase in attempt time beyond 40 seconds. Conclusion: Skill improved from first year to second year. Most intubations exceeded 30 second time limit. There is a need to improve training methodology to ensure intubation time by health personnel does not exceed the expected time limit.

Effect of chlorhexidine, povidone iodine, and ozone on microorganisms in dental aerosols: Randomized double-blind clinical trial.

Objective: Dental handpieces, ultrasonic scalers, air polishers, air abrasion units produce the most visible aerosols. The objective of this study was to assess the effect of chlorhexidine (CHX), povidone iodine (PI), and ozone (OZ) on the microorganisms in dental aerosols. Materials and Methods: A total of 60 patients were included in this study, they were randomly assigned into three groups and were subjected to scaling before and after rinsing with 0.2% CHX, 1% PI or irrigation with OZ. Blood agar plates were used to collect the gravitometric settling of aerosols and were sent for aerobic and anaerobic culture. Results: The results demonstrated high percentage reduction of aerobic and anaerobic colony forming units (CFUs) in all three groups. In aerobic CFUs, CHX showed the highest reduction (57%) at mask position whereas at chest position and at 9 ft, PI showed higher CFU reductions (37% and 47%, respectively). In anaerobic CFUs, CHX showed the highest percentage of reduction at chest level (43%) and at 9 ft (44%). Conclusion: CHX, PI and OZ showed similar effects in reducing aerobic and anaerobic CFU's at the chest mask and at 9 ft. OZ can be used as a preprocedural agent, considering its beneficial effects.
