Background and Purpose : Allergic rhinitis is a well-known, relatively controllable chronic disease. Although a number of methods for treating allergic rhinitis have been tried, many patients have not been satisfied with their treatment. Therefore, this study tried to evaluate the effect of a cooperative system of Oriental and Western medicine and to develop a new diagnosis protocol for treatment of allergic rhinitis. Methods : We measured improvement rate and acoustic rhinometry after the allergeninduction test and performed a filter paper test as a nonspecific hypersensitivity test with 60 patients who are allergic to house dust mite. Patients were divided into two groups, one treated with Western medicine only and one treated with both Western and Oriental herbal medicine. For the group with Western medicine only, antihistamine for one week and local steroid medicine for two weeks were prescribed. For the group with combined medicine, Oriental herbal medicine was prescribed according to the patient s constitution, along with Western medicine. After all treatments, the above tests were re-performed and the improvement rate was compared. Results and Conclusion : We observed better results in the group treated with both Western and Oriental herbal medicines, comparing improvement rate and the alteration of total nasal volume through acoustic rhinometry after the allergen induction test. In the filter paper test, there was no significant difference between the two groups. In conclusion, we showed the additive effect of Oriental herbal medicine without any severe side effects compared with treatment with Western medicine only. In this study, we set only two patient groups, but further study is required to create various experimental groups and compare among them. We suggest that it might enhance understanding of the improved effect of Oriental herbal medicine in the therapy of allergic rhinitis.

Cervical cancer is an issue of foremost importance globally, specifically affecting the developing nations. Significant advances have taken place with regard to diagnosis of cervical cancer, especially with screening. Appropriate screening measures can thus reduce the incidence of cervical cancer. The most desirable screening technique should be less invasive, easy to perform, cost-effective and cover a wide range of diagnostic icons. Manual liquid based cytology (MLBC) can be considered as one of the suitable technique for screening with the above-mentioned benefits. The aim of the current study was to compare two cervical screening techniques on the basis of different morphological parameters and staining parameters by using modified acetic acid Pap staining to see the possibility of reducing time economy involved in conventional Pap staining (CPS). The study was conducted on a total 88 cases and all were analyzed with both MLBC and CPS. Forty eight cases that were regarded as satisfactory on the basis of Bethesda system by both methods were further recruited for investigation. Their morphological parameters and staining quality were compared and scored according to a scoring system defined in the study. Quality indices was calculated for both staining procedures and smear techniques.
OBJECTIVE: False negatives of cervical smears due to screening errors pose a significant and persistent problem. AutoPap 300 QC System, an automated screening device, is designed to rescreen conventionally prepared Pap smears initially screened by cytotechnologists as normal. Clinical experience and sensitivity of the AutoPap 300 QC System were assessed and compared with current 10% random qualify control technique. MATERIALS AND METHODS: In clinical practice, a total of 18,592 "within normal limits" or "benign cellular changes" cases classified by The Bethesda System were rescreened by the Autopap System. In study for sensitivity of The AutoPap System to detect false negatives, a total of 1,680 "within normal limits" or "benign cellular changes" cases were rescreened both manually and by the AutoPap System. The sensitivity of the AutoPap System to these false negatives was assessed at 10% review rate to compare 10% random manual rescreen. RESULTS: In clinical practice, 38 false negatives were identified by the AutoPap System and we had achieved 0.2% reduction in the false negative rate of screening error. In study for sensitivity, 37 false negatives were identified by manual rescreening, and 23 cases(62.2%) of the abnormal squamous cytology were detected by the AutoPap System at 10% review rate. CONCLUSONS: The AutoPap 300 QC System is a sensitive automated rescreening device that can detect potential false negatives prior to reporting and can reduce false negative rates in the laboratory. The device is confirmed to be about eight times superior to the 10% random rescreen in detecting false negatives.
This study was conducted to 1206 women who had cervical cancer screening at Chonburi Cancer Hospital. The spilt-sample study aimed to compare the efficacy of abnormal cervical cells detection between liquid-based cytology (LBC) and conventional cytology (CC). The collection of cervical cells was performed by broom and directly smeared on a glass slide for CC then the rest of specimen was prepared for LBC. All slides were evaluated and classified by The Bethesda System. The results of the two cytological tests were compared to the gold standard. The LBC smear significantly decreased inflammatory cell and thick smear on slides. These two techniques were not difference in detection rate of abnormal cytology and had high cytological diagnostic agreement of 95.7%. The histologic diagnosis of cervical tissue was used as the gold standard in 103 cases. Sensitivity, specificity, positive predictive value, negative predictive value, false positive, false negative and accuracy of LBC at ASC-US cut off were 81.4, 75.0, 70.0, 84.9, 25.0, 18.6 and 77.7%, respectively. CC had higher false positive and false negative than LBC. LBC had shown higher sensitivity, specificity, PPV, NPV and accuracy than CC but no statistical significance. In conclusion, LBC method can improve specimen quality, more sensitive, specific and accurate at ASC-US cut off and as effective as CC in detecting cervical epithelial cell abnormalities.
The detection of high-risk human papilloma virus (HPV) allows us to predict the presence and future development of cervical intraepitheliallesion. In this study, we compared Hybrid Capture II and DNA chip methods for detection of HPV in cervical swab samples. And we evaluated the clinical efficacy and diagnostic performance of HPV DNA chip and Hybrid Capture II for detecting HPV in cervical neoplastic lesions. Seventy four patients were classified into three groups according to their histologic diagnosis: Group I (nonspecific chronic cervicitis), Group II (low-grade squamous intraepithelial lesion (SIL); koilocytosis, and mild dysplasia), and Group III (high-grade SIL;, moderate, severe dysplasia and in situ carcinoma). Cytologic diagnosis were based on the Bethesda System. Hybrid Capture II and DNA chip methods were performed to detect HPV. In 41 of the 74 cervical samples $(55.4\%)$, HPV DNAs were detected by Hybrid Capture II. In Group III, HPV-positive cases were detected in 15 $(20.3\%)$ of 74 patients by Hybrid Capture II. 25 patients with ASCUS cytology were histopathologically examined: 9 cases $(36\%)$ were Group II. In 18 patients with low-grade SIL cytology, 13 cases $(72.2\%)$ were Group II and 3 cases $(16.7\%)$ were Group III. 12 cases $(92.3\%)$ were Group ill of 13 patients with high-grade SIL cytology. The sensitivity of each test was $82\%$ in Hybrid Capture II and $53.9\%$ in DNA chip test. And the specificity was $74.3\%,\;85.7\%$ in Hybrid Capture II and DNA chip. In conclusion, Hybrid Capture II test is more sensitive than DNA chip in detecting women with cervical neoplastic lesions. Especially, in diagnosing of ASCUS, Hybrid Capture II test is more sensitive. Therefore, Hybrid Capture II test for cancer-associated HPV DNA is a viable option in the management of women with ASCUS.
This study was performed to compare manual liquid-based preparation with conventional Papanicolaou tests in view of the cytologic diagnoses and specimen adequacy. The specimens of 5,979 women from 33 local clinics and 1 general hospital were prepared by both manual liquid-based preparation and conventional Papanicolaou test. The cytologic diagnoses and specimen adequacy were evaluated in Department of Fathology in Kyoungpook National University School of Medicine. A conventional Papanicolaou test was always prepared first, after that residual material on the sampling device was rinsed into a liquid preservative, and then thin-layer slides were prepared using manual method of liquid-based cervicovaginal cytology. Conventional and liquid-based slides were read independently, and cytologic diagnoses and specimen adequacy were classified using the Bethesda System. Of the cases, 5,763 (96.3%,) had the same interpretation, and there was no significant diagnostic difference in 5,853 (97.8%) cases. When evaluating cases with more than one diagnostic class difference, the manual liquid-based preparation demonstrated a statistically significant overall improvement (2.1%) in the detection of squamous intraepithelial lesion and invasive cancer. Using manual method of liquid-based preparation, there was 14.1%, reduction in unsatisfactory slides through excellent cellular presentation. In conclusion, the manual liquid-based preparation produces standardized quality, superior sensitivity and improved adequacy as compared to the conventional method.
Background: The Bethesda System for Reporting Thyroid Cytopathology is one of the main classification systems for thyroid nodules. It expects that 7% of all fine needle aspiration biopsies will be reported as atypia or follicular lesions of undetermined significance, and 5-15% of these undetermined nodules are malignant. Our study is a retrospective analysis of variables that may be associated with outcome in patients with indeterminate thyroid nodules. Materials and Methods: Patients who underwent thyroidectomy in our institution between 2010 and 2014 were retrieved from the institutional records database. Patient demographics and medical histories were recorded. All ultrasonography reports were examined for nodule features and biochemical blood levels, hormone levels and complete blood counts were recorded. Results: A total of 103 patient cytopathology reports were regarded as belonging to the undetermined category. Some 35% of patients had malignant nodules. Median preoperative red cell distribution width (RDW) level was 13.6 inthe benign group, while it was 14.3 in patients with malignancy, demonstrating a significant correlation (p=0.003). Only calcification presence was significantly different between benign and malignant groups on ultrasonography (p=0.034). Conclusions: Ultrasonography is one of the primary tools for this matter. RDW levels may become another promising tool to predict malignancy.

Objectives: To determine human papillomavirus (HPV) frequency, genotypes and the relation between cervical smear results, risk factors and types in women living in Manisa, Turkey. Materials and Methods: A total of 410 women were included in the study. Cervical specimens were obtained for linear array HPV genotyping and pathological testing. Conventional Pap test and Bethesda system were used for evaluation of cytology specimens. Results: A total of 410 women with a mean age of 34.9 years were tested. A positive result of any HPV was found in 35 patients (8.5%). Among them, 26 different serotypes of HPV were identified and the most frequent type was HPV 16 (28.5%) followed by type 45 and 53 (11.4%). Patients were infected by 65.7% high risk, 11.4% probable high risk and 22.9% low risk HPV types. Multiple HPV positive results were found in 13 patients (37.1%). Patients with single partner, history of abnormal smear or condyloma had positive HPV results and this was statistically significant (p<0.05). Correlation analysis showed a statistically weak relation between positive HPV and abnormal smear results (r=0.120). Conclusions: Determining HPV types of genital HPV infections is important for epidemiological studies. We have found the rate of positive HPV as 8.5% which implies the need for extended screening programs in order to diagnose oncogenic HPV at an early stage.
Purpose: To determine the prevalence of abnormal cervical cytology, as diagnosed using a liquid-based cytology technique, in pregnant women attending the Antenatal Care (ANC) clinic at Siriraj Hospital. Materials and Methods: This cross-sectional study included 655 first-visit pregnant women who attended ANC clinic at Siriraj Hospital during June to November 2015 study period. After receiving routine antenatal care, cervical cytology screening was performed with the Siriraj liquid-based cytology technique. All specimens were reviewed by a certified cytopathologist using Bethesda System 2001 criteria. Patients with abnormal PAP results characterized as epithelial cell abnormalities were referred to a gynecologic oncologist for further management according to ASCCP Guidelines 2012. Results: Mean age of participants was $28.9{\pm}6.2$ years. Prevalence of abnormal cervical cytology was 3.4% (95% CI: 2.0-4.7). Among this group, there were ASC-US, ASC-H, LSIL, HSIL for 12(1.8%), 2(0.3%), 7(1.1%) and 1(0.2%), respectively. In 633 specimens of the normal group, infection was identified in 158 specimens (24.1%) which were caused by Candida spp. and Trichomonas vaginalis. Regarding patient perception about the importance of cervical cancer screening, although most women perceived screening to be important, 54% of participants had never been screened for cervical cancer. Rate of loss to follow-up in the postpartum period was as high as 41.8%. Conclusions: Prevalence of abnormal cervical cytology in pregnant women attending the ANC clinic at Siriraj Hospital was 3.4%. Inclusion of cervical cancer screening as part of antenatal assessment can help to identify precancerous lesions or cervical cancers in patients who might otherwise not be screened, thereby facilitating early treatment and improved patient outcomes.
Purpose: To study clinical factors related to adequacy of transformation zone (TZ) components in cervical smears. Materials and Methods: Medical and Papanicolaou (Pap) smear reports from Thammasat University Hospital, Thailand during January to December 2015 were collected. Demographic data was reviewed by attending physicians and impact of clinical factors onTZ adequacy was primary outcome. A total of 3,251 smears were reviewed. Finally, 2,098 smears met The inclusion criteria and enrolled into this study. Results: Average age and bodyweight of participants in this study were 43.0 years and 60.0 kg, respectively. Ninety seven percent of smears were classified as satisfactory for evaluation according to the Bethesda system 2001. Adequacy (group A) and inadequacy (group B) of TZ were equal in percentage (50.9/46.0). Prevalence of abnormal cervical cytology was 4.4%. Percentages of abnormal Pap smears in group A and B were 7.3 and 1.4, respectively (p<0.001). Factors associated with increased adequacy of TZ were old-age (${\geq}50yr$), nulliparity, within 3-months postpartum, history of TZ inadequacy and abnormal smears. Sexually transmitted disease (STD), hormonal usage, previous cryotherapy and smears collected by staff were associated with inadequacy of TZ. Conclusions: Collection of cervical specimens should be carefully performed. STD history, hormonal usage and previous cryotherapy are risk factors for TZ inadequate specimens.
