Immediate histopathologic correlation in Turkish population with negative cytology and high-risk human papillomavirus positivity: A retrospective analysis of high-risk human papillomavirus genotype and stratified by age.

INTRODUCTION: According to the American Society of Colposcopy and Cervical Pathology (ASCCP) recommendations, regardless of age, women with high-risk infections other than human papillomavirus 16/18 positivity (other hrHPV) and negative cytology should not be referred directly to colposcopy. Several studies compared detection rates of ≥high-grade squamous intraepithelial lesion (HSIL) between HPV 16/18 ± 45, and other hrHPV types on colposcopic biopsy. METHODS: We designed a retrospective study to determine the presence of ≥HSIL in colposcopic biopsy in women with negative cytology and hrHPV positivity during the years 2016-2022. RESULTS: HPV 16/18/45 had a PPV of 43.8%, while other hrHPV types had a PPV of 29.1% for a tissue diagnosis of ≥HSIL. For a tissue diagnosis of ≥HSIL detection, there was no statistically significant difference between the PPV of other hrHPV and HPV 16/18/45 in patients ≥30. There were only two cases with a tissue diagnosis of ≥HSIL in the other hrHPV group of women under 30 years of age. CONCLUSION: We suggested that the follow-up recommendations of ASCCP for patients above the age of 30 with negative cytology and other hrHPV positivity may not be fully applicable to countries like Turkey with a different healthcare environment. Referring to patients ≥30 who had other hrHPV positivity and negative cytology to direct colposcopy may be clinically beneficial, particularly in populations where a colposcopic examination is easy and inexpensive.

Evaluation of the Relationship Between Transcutaneous Bilirubin Measurement and Total Serum Bilirubin in Neonatal Patients Followed for Jaundice.

OBJECTIVES: Jaundice is a physiological condition caused by hyperbilirubinemia, which is common in neonatal period. However, severe hyperbilirubinemia can cause kernicterus, which is a serious condition that leads to neurological problems. In this study, we aimed to investigate whether it is safe to use transcutaneous bilirubin (TcB) instead of blood for the evaluation of jaundice by comparing TcB measurement with standard total serum bilirubin (TSB) measurement values. METHODS: A total of 105 term and early term infants with gestational ages between 37 and 42 weeks were included in the study. MBJ20 TcB measuring device was used for TcB measurement. TcB was measured from the forehead and sternum. To evaluate the relationship between TcB measurements and TSB measurements, we performed Pearson correlation, Spearman correlation, linear regression analysis, and Bland-Altman analysis in which we evaluated the scatter plot of the differences between the average values of the measurements. RESULTS: There was a positive and statistically significant correlation between TcB forehead and TSB measurements and TcB sternum and TSB measurements (p<0.001). Linear regression analysis showed a positive directional correlation between TcB forehead and TSB measurements (R²=0.85) and TcB sternum and TSB measurements (R²=0.87). Bland-Altman analysis showed a good consistency between TSB and TcB forehead measurement methods (mean difference: 0.39±1.46, 95% CI: [-2.47]-[3.26]), and between TSB and TcB sternum measurement methods (mean difference: 0.49±1.32 95% CI: [-2.1]-[3.07]). CONCLUSION: As a result of our study, we found that TcB measurement can be reliable instead of taking blood for jaundice evaluation.

The Relationship between COVID-19 Severity and Bacillus Calmette-Guérin (BCG)/ Mycobacterium tuberculosis exposure history in healthcare workers: a multi-center study.

The COVID-19 pandemic has brought countries' health services into sharp focus. It was drawn to our group's attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.
