OBJECTIVES:
Papular dermatoses commonly affecting the female vulva, such as molluscum contagiosum, syringoma, lymphangioma, folliculitis, verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis, often present with similar clinical appearances and are frequently misdiagnosed. This study aims to explore the clinical diagnostic value of reflectance confocal microscopy (RCM) in differentiating these conditions.
METHODS:
A retrospective analysis was conducted on RCM imaging and histopathological findings from lesion sites in 172 female patients with vulval papular dermatoses. RCM characteristics confirmed by biopsy were summarized and diagnostic clues were explored.
RESULTS:
RCM diagnosis was consistent with histopathological diagnosis in 147 out of 172 cases (85.47%). Molluscum contagiosum, syringoma, lymphangioma, and folliculitis all exhibited cystic-like structures under RCM, differing in the location of the structures, wall characteristics, internal contents, and reflectivity. Verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis lacked such structures. Verruca vulgaris showed distinctive low-refractive vacuolated cells in the spinous layer; bowenoid papulosis exhibited mild cytologic atypia in the spinous layer; ectopic sebaceous glands were characterized by moderately to low-refractive, fish roe-like sebaceous lobules within the dermis.
CONCLUSIONS
RCM enables noninvasive, real-time, and dynamic visualization of key diagnostic and differential features of common vulvar papular dermatoses in women, offering high diagnostic value.

OBJECTIVE:
To evaluate the effectiveness and safety of Chinese medicine (CM) in the treatment of coronavirus disease 2019 (COVID-19) in China.
METHODS:
A multi-center retrospective cohort study was carried out, with cumulative CM treatment period of ⩾3 days during hospitalization as exposure. Data came from consecutive inpatients from December 19, 2019 to May 16, 2020 in 4 medical centers in Wuhan, China. After data extraction, verification and cleaning, confounding factors were adjusted by inverse probability of treatment weighting (IPTW), and the Cox proportional hazards regression model was used for statistical analysis.
RESULTS:
A total of 2,272 COVID-19 patients were included. There were 1,684 patients in the CM group and 588 patients in the control group. Compared with the control group, the hazard ratio (HR) for the deterioration rate in the CM group was 0.52 [95% confidence interval (CI): 0.41 to 0.64, P<0.001]. The results were consistent across patients of varying severity at admission, and the robustness of the results were confirmed by 3 sensitivity analyses. In addition, the HR for all-cause mortality in the CM group was 0.29 (95% CI: 0.19 to 0.44, P<0.001). Regarding of safety, the proportion of patients with abnormal liver function or renal function in the CM group was smaller.
CONCLUSION
This real-world study indicates that the combination of a full-course CM therapy on the basic conventional treatment, may safely reduce the deterioration rate and all-cause mortality of COVID-19 patients. This result can provide the new evidence to support the current treatment of COVID-19. Additional prospective clinical trial is needed to evaluate the efficacy and safety of specific CM interventions. (Registration No. ChiCTR2200062917).
