The positive margins after LEEP(loop electrosurgical excision procedure) in cervical intraepithelial neoplasia are generally considered to be a risk factor for the recurrence or persistence of CIN currently. When positive margin exists, secondary LEEP or hysterectomy is performed. The aim of this study was to observe effects of Traditional Korean Medicine treatment for patients with surgical margin positive after LEEP. It was conducted retrospective chart review for 4 patients with the surgical margin positive after LEEP, who were scheduled to have secondary LEEP 3 months later. Patients were treated with herbal medicine, pharmacopuncture and herbal liquid vaginal treatment. They were followed up by cytology, colposcopy, human papillomavirus DNA test and punch-biopsy at 1, 3 and 6 months. After 3 month of treatment, three patients did not need secondary LEEP because of normal cytology, negative HPV status and normal colposcopy, while the other patient underwent secondary LEEP because of ASCUS cytology and positive high-risk HPV. After 6 month of treatment, the other patient also had normal cytology, negative HPV status and normal colposcopy and had been in fifth week of pregnancy. This study suggest that Traditional Korean Medicine treatment may be an effective to the patients with surgical margin positive after LEEP in cervical intraepithelial neoplasia.

Objectives: The purpose of this study is to analyze the domestic study trends of pharmacopuncture therapy on obstetrics and gynecological diseases in Korean literature, through reviewing the clinical and experimental studies. Methods: We searched for clinical and experimental studies using pharmacopuncture therapy on obstetrics and gynecological diseases, published from January 2000 to May 2019, through 5 Korean databases. The study design, target disease, type of pharmacopuncture, method of intervention, and study results were analyzed. Results: 36 experimental studies and 15 clinical studies were finally included according to inclusion and exclusion criteria. In experimental studies, there were 12 studies about postmenopausal osteoporosis, 9 studies about obesity, 4 studies about endometriosis, 3 studies about hemostatic effects and analgesic anticoagulative effects, 2 studies about ovarian function, and analgesic antiphlogistic anticoagulative effects, and 1 study about menopausal symptoms. In clinical studies, there were 3 studies about obesity, postpartum disorders, dysmenorrhea, and women's urologic disease, and 1 study about menopausal symptoms, atypical squamous cells of undetermined significance (ASCUS) and breast cancer. Various types of pharmacopuncture have been proved to have a therapeutic effect in each of those obstetrics and gynecological diseases. Conclusions: This study indicates that pharmacopuncture therapy could be a good treatment for obstetrics and gynecological diseases. However, more well-designed and high-quality clinical researches are needed in further studies, to prove the effectiveness and safety of pharmacopuncture therapy.

To prevent cervical cancer, human papillomavirus (HPV) bivalent and quadrivalent vaccinations are common, but there is a need for a vaccination system based on the high-risk human papillomavirus (HR-HPV) genotype that differs by region. This study aimed to investigate the prevalence of HPV and the distribution of HR-HPV genotypes in 2,014 women who were not vaccinated against HPV. In this study, HPV DNA testing was performed on 2,014 women not vaccinated against HPV and who visited the Busan Obstetrics and Gynecology Department from September 2020 to July 2021. In addition, liquid-based cytology (LBC) test was performed on 493 cases of HR- HPV genotype infection confirmed by HPV DNA test. The prevalence of HPV among women in Busan was positive in 609 (30.2%) out of 2,014 cases. Among the 609 HPV-positive cases, HR-HPV infection accounted for 493 cases (81.0%), which is a high proportion. Of the total 493 HR-HPV infection cases, liquid-based cytology (LBC) was within normal limits (WNL) in 266 cases (54.0%), atypical squamous cells of undetermined significance (ASCUS) in 97 cases (19.7%), low-grade squamous intraepithelial lesion (LGSIL) in 88 cases (17.8%), and high-grade squamous intraepithelial lesion (HGSIL) in 42 cases (8.5%). Single HR-HPV 52 and 16 accounted for the highest and second highest infection rates, respectively. The high infection rate among women aged 18~39 underscores the need for continuous monitoring. In addition, when there were abnormal findings in the cervical epithelium, HPV 52 was the most common, while in the case of HGSIL, HPV 16 was the most common. The HR-HPV genotypes related to cervical cancer should be continuously collected and monitored for use in health policies, including local and national vaccinations.

The Bethesda System (TBS) was first developed in 1988 for the need to enhance the communication of the cytopathologic findings to the referring physician in unambiguous diagnostic terms. The terminology used in this reporting system should reflect current understanding of the pathogenesis of cervical/vaginal disease so the framework of the reporting system should be flexible enough to accommodate advances in medicine including virology, molecular biology, and pathology. Three years after the Introduction of TBS, the second Bethesda workshop was held to set or amend diagnostic criteria for each categories of TBS. TBS 1991 is now widely used. The third Bethesda workshop, The Bethesda System 2001 Workshop, was held in National Cancer institute Bethesda, Maryland from April 30 to May 2, 2001. Again, the goals of this workshop were to promote effective communication and to clarify in reporting cervical cytopathology results to clinicians and to provide with the information to make appropriate decisions about diagnosis and treatment. Nine forum groups were made and there were Web-based bulletin board discussions between October, 2000 and the first week of April, 2001. On the basis of bulletin board comments and discussions, the forum moderators recommended revised terminologies in the Workshop. Hot discussions were followed after the presentation by forum moderators during the workshop. Terminologies confusing clinicians and providing no additional informations regarding patient management were deleted in the workshop to clarify the cervicovaginal cytology results. Any informations related to the patient management were encouraged to add. So 'Satisfactory for evaluation but limited by...' of 'Specimen Adequacy' catergory was deleted. Terminology of 'Unsatisfactory' was further specified as 'Specimen rejected' and 'Specimen processed and examined, but unsatisfactory'. Terminologies of 'Benign Cellular Change' and 'Within Normal Limits' were combined and terminology was changed to 'Negative for intraepithelial lesion or malignancy'. In General categorization, category 'Other' was newly inserted and the presence of 'Endometrial cells' in women over 40 years old can be checked. Although the category 'Benign Cellular Change' was deleted, the organisms or reactive changes of this category can be listed in the descriptive diagnoses. Terminologies of ASCUS and AGUS were changed to atypical squamous cell and atypical glandular cell, respectively. Diagnostic term of 'Adenocarcinoma in situ', which is highly reproducible with reliable diagnostic criteria, was newly Inserted. The category of hormonal evaluation was deleted. Criteria for liquid-based specimen were discussed. Reporting by computer-assisted cytology was discussed and terminology for automated review was newly inserted. This is not the final edition of Bethesda 2001. The final document can be prepared before the ASCCP meeting in which Consensus Guidelines for the Management on Cytology Abnormalities and Cervical Precursors will develop in September 2001.

The circular leaf spot of persimmon is occurred almost every place where persimmon is cultivated, especially the disease outbreak severely in southern part of Korea. The disease reveals unusually long incubation period after pathogen invade into leaf tissue and no practical control measure is available once the symptom has appeared. Most of the farmers just follow the suggested spray schedules calculated on the basis of weather condition of ordinary years. Therefore the damages due to circular leaf spot greatly differ year after year. In this article, we tried to describe and summarized the investigation on the circular leaf spot pathogen, Mycosphaerella nawae, related to disease outbreak such as overwintering of pathogen, inoculum formation and spread, incubation period after infection, and secondary inoculum. With the summary of these results, we suggest the disease cycle of circular leaf spot of persimmon. The pathogen overwinters in diseased leaves as mycelial form or pseudoperithecial premodium. The pseudoperitheria become matured in spring as the temperature raise and forms asci and ascospores. The maturation of pseudoperithecia are closely related to the temperatures during March and early April. The ascospores completely mature in early May and the ascospores released when the pseudoperithecia absorbed enough moisture after rainfall. The release of ascospores are diverse greatly with the variation of maturity of pseudoperithecia. Generally the spore start to release from middle of May to early of July. Duration of ascospore release is depend on the weather condition of particular year, especially amount and number of precipitation. The ascospores produced from pseudoperithecia is known to the only inoculum for circular leaf spot disease. But according to the results obtained from our investigations, the conidia formed on the lesions which incited by natural infection. This conidia are infectious to persimmon leaves and formed identical symptom as natural infection. The time of producing secondary inoculum of circular leaf spot of persimmon is considered too late to develop new disease. Generally the importance of secondary inoculum is low but the conidia produced in early September are competent to develop new disease and new infection also significantly affect to harvest of persimmon. The importance of circular leaf spot disease is recognized well to farmers. The approaches to control of the disease should be initiated on the basis of the knowledges of inoculum dynamics and ecology of disease development. The forecasting system for circular leaf spot is need to be developed.

Objective: To investigate the diagnostic value of the R-way colposcopic evaluation system (R-way system) in cervical cancer screening. Materials and Methods: Between August 2013 and August 2014, a total of 1,059 cases referred to colposcopy in Peking University First Hospital were studied using both the R-way system and conventional colposcopy. Our study evaluated and compared the diagnostic ability of the two methods in detecting high-grade lesions and cervical cancer (hereinafter called CIN2+). Evaluation indicators including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), Youden index and the area under the curve (AUC) of the receiver operating characteristic (ROC) were calculated. Results: The R-way system had a slightly lower specificity (94.5%) than conventional colposcopy (96.0%) for CIN2+ detection (P=0.181). However, the sensitivity (77.8%) was significantly higher than with the conventional colposcopic method (46.6%) (${\chi}^2=64.351$, P<0.001). In addition, the AUC of the ROC for CIN2+ detection using the R-way system (0.839) was larger than that with conventional colposcopy (0.731) (Z=4.348, P<0.001). If preliminary result had been drawn from cervical exfoliated cytology before colposcopy referral, combination of the R-way system with cytology could increase the sensitivity to 93.9% for CIN2+ detection (excluding ASCUS\LSIL), confirmed by multipoint biopsy or ECC. Conclusions: The diagnostic value of the R-way evaluation system is higher than that of conventional colposcopic evaluation in cervical cancer screening. Moreover, taking the ease of use and standardized quality control management into account, the R-way system is highly preferable.

Background: Cervical cancer is the second most common cancer in Thai women after breast cancer. Currently, the Papanicolaou (Pap) smear is the recommended procedure for cervical cancer screening in Thailand, but only a relatively small percentage of women follow this screening program. An alternative method to detect HPV genotypes associated with cervical cancer is self-sampling of urine, which is a more widely accepted method. Our study aimed to evaluate the prevalence of HPV in Thai women using urine and cervical swabs and prevalence of HPV in Thai men using urine samples. Materials and Methods: Tumorigenic HPV detection was accomplished by electrochemical DNA chip and PCR/direct sequencing. In addition to HPV prevalence, we report the concordance between different methods and sample types. One-hundred and sixteen women and 100 men were recruited. Histological examination revealed normal cytology in 52 women, atypical squamous cells of undetermined significance (ASCUS) in 9, low-grade squamous intraepithelial lesions (LSIL) in 24, and high-grade squamous intraepithelial lesions (HSIL) in 31. One-hundred men were classified as heterosexuals (n=45) and homosexuals (n=55). Results: The most prevalent HPV genotype in our study was HPV16. The HPV detection rate was generally lower in urine samples compared with cervical samples. Overall, there was good agreement for the detection of carcinogenic HPV from female cervical samples between the DNA chip and PCR/sequencing, with 88.8% total agreement and a kappa value of 0.76. In male urine samples, the level of agreement was higher in heterosexuals compared with homosexuals. Conclusions: Further improvement is required to increase an overall yield of HPV DNA detection in urine samples before clinical application of a urine-based HPV screening program. The electrochemical DNA chip test is a promising technique for carcinogenic HPV detection.

A novel species, Metschnikowia cibodasensis, is proposed to accommodate eight strains (ID03-$0093^T$, ID03-0094, ID03-0095, ID03-0096, ID03-0097, ID03-0098, ID03-0099, and ID03-0109) isolated from flowers of Saurauia pendula, Berberis nepalensis, and Brunfelsia americana in Cibodas Botanical Garden, West Java, Indonesia. The type strain of M. cibodasensis is ID03-$0093^T$ (= NBRC $101693^T$ =UICC $Y-335^T$ = BTCC-$Y25^T$). The common features of M. cibodasensis are a spherical to ellipsoidopedunculate shaped ascus, which contains one or two needle-shaped ascospores, and lyse at maturity. Asci generally develop directly from vegetative cells but sometimes from chlamydospores. The neighbor-joining tree based on the D1/D2 domain of nuclear large subunit (nLSU) ribosomal DNA sequences strongly supports that M. cibodasensis (eight strains) and its closest teleomorphic species, M. reukaufii, are different species by a 100% bootstrap value. The type strain of M. cibodasensis, ID03-$0093^T$, differed from M. reukaufii NBRC $1679^T$ by six nt (five substitutions and one deletion) in their D1/D2 region of nLSU rDNA, and by 18 nt (five deletions, four insertions, and nine substitutions) in their internal transcribed spacer regions of rDNA, respectively. Four strains representative of M. cibodasensis (ID03-$0093^T$, ID03-0095, ID03-0096, and ID03-0099) showed a mol% G+C content of $44.05{\pm}0.25%$, whereas that of M. reukaufii NBRC $1679^T$ was 41.3%. The low value of DNA-DNA homology (5-16%) in four strains of M. cibodasensis and M. reukaufii NBRC $1679^T$ strongly supported that these strains represent a distinct species.
