Purpose: To analyze the repeatability of manual measurement of foveal avascular zone (FAZ) area in an optical coherence tomography angiography (OCTA) image in high myopia. Methods: This study comprised patients with high myopia and controls. Two consecutive FAZ areas of the superficial and deep capillary plexus were obtained using OCTA. The intraclass correlation coefficient (ICC) and coefficient of variation (CV) were assessed, and univariate and multivariate generalized linear mixed models were conducted to identify factors related to repeatability. Results: Thirty eyes with high myopia and 34 eyes of healthy subjects were included in the study. The mean age in high myopia and control subjects was 55.5 and 60.8 years, respectively, the mean spherical equivalent was −9.98 and −0.55 diopters, and the mean axial length was 28.0 and 23.9 mm. The ICCs of FAZ area of the superficial capillary plexus (SCP) were 0.891 and 0.919, while the CVs were 8.8% and 8.5%. In measurement of the deep capillary plexus, the ICCs were 0.788 and 0.907, while the CVs were 11.2% and 11.0%, which were acceptable but exhibited lower repeatability than those of SCP. Multivariate analyses showed that older age (p = 0.030) and greater axial length (p = 0.005) were significantly associated with lower repeatability of SCP FAZ area measurements. In addition, greater axial length (p = 0.044) was a significant factor for lower repeatability of deep capillary plexus FAZ area measurements. Conclusions Manual measurement of FAZ area using OCTA exhibited relatively good repeatability for high myopia. Age and axial length affected repeatability and should be considered when analyzing FAZ areas in high myopia patients.

E6 and E7 proteins produced by oncogenic HPV bind to the protein products of cellular tumor suppressor genes p53 and Rb, respectively. This mechanism has been suggested to contribute to the oncogenesis of HPV-infected carcinoma. The cells which are blocked the function of p53 and pub protein continue to divide by bypassing Ml stage known as antiproliferative mechanism but telomeres, the genetic elements at the ends of chromosomes, continue to shorten until the telomeres are so short that further replication is prevented(M2 stage). But telomeres can be maintained if telomerase is derepressed, giving rise to a immortal cell. The present study has been investigated the presence of HPV, telomere length and telomerase activation in cervical carcinomas. HPV DNA were detected by polymerase chain reaction in 17 of 19 precancerous lesions and cervical carcinoma specimens; HPV16 was detected in 12 cases, HPV18 in one case, HPV33 in two cases, and HPV58 in two cases. Overall, the prevalence of HPV was 89.5%. To study the difference of telomere length in cervical carcinomas and each normal counterpart, DNAs were digested with Hinf III and Rsa I to liberate the terminal restriction fragments(TRF). TRFs were resolved on agarose gels and detected by hybridization to the telomeric probe. This result indicated that there were no significant difference of TRF length in samples tested except two cases. TRF length of one carcinoma specimen was found to be significantly increased as compared with normal counterpart, but the other was found to be significantly decreased. Telomerase activity was detected in 4 of dysplasia specimens(5 cases), all of carcinoma in situ(CIS), and 6 of 8 invasive carcinoma. Overall, telomerase activity was detected in 84%. The degree of telomerase activity was high in 2 of dysplasia, 3 of CIS, and 3 of invasive carcinoma. And then there was no apparent association between HPV types and levels of telomerase activity. However, telomerase activity was depressed in invasive carcinoma as compared to dysplasia and CIS. These results suggest that HPV may be a possible causative agent in cervical carcinoma. In addition, telomerase activation may be necessary for the immortalization of cells and the progression of malignancy in cervical carcinoma.

BACKGROUND: Dermoscopy is a real-time, noninvasive technique that increases the diagnostic accuracy of clinical evaluation by the dermatologist. Characterization of facial actinic keratosis via dermoscopy is valuable in guiding the dermatologist in the differential diagnosis of facial skin lesions. To our knowledge, dermoscopic evaluation of actinic keratosis has not yet been reported in Korean literature. OBJECTIVE: The purpose of this study was to investigate the dermoscopic features of facial actinic keratosis in Koreans. METHODS: We examined 60 patients with facial actinic keratosis using dermoscopy. We determined the frequency of specific features revealed by dermoscopy across the Korean patient population and compared our results with those of other published studies. RESULTS: A total of 67 facial actinic keratoses were observed in 60 patients. The common features of non-pigmented actinic keratoses revealed by dermoscopy were a red pseudo-network (66%), white-to-yellow surface scales (48.9%), linear wavy vessels (38.3%), and targetoid hair follicles (42.6%). The common features of pigmented actinic keratoses revealed by dermoscopy were slate-grey dots (55%) and globules (30%), annular-granular pattern (35%), a brown-to-gray pseudo-network (40%), and targetoid hair follicles (30%). The frequency of specific features revealed by dermoscopy across the analyzed patient population was not significantly different from that reported in other studies, except for rhomboidal structures (5%), which was lower in Koreans than in other populations (35.8%, p<0.05). The frequency of dermoscopic features was different according to histopathologic subtypes (hypertrophic, atrophic, bowenoid, acantholytic actinic keratosis). CONCLUSION: Dermoscopy revealed specific features of facial actinic keratosis that can be utilized to evaluate and diagnose facial skin lesions.
