Our study is to determine the presence of endometrial intraepithelial neoplasia (EIN) in endometrial biopsy specimens classified by the 1994 World Health Organization (WHO) criteria for endometrial hyperplasia. Endometrial biopsy specimens that were stained with hematoxylin and eosin (HE) were examined and categorized by the WHO 1994 criteria and for the presence of EIN as defined by the International Endometrial Collaborative Group. ${\beta}$-catenin expression was examined by immunohistochemistry. A total of 474 cases of HE stained endometrial biopsy tissues were reviewed. There were 379 cases of simple endometrial hyperplasia, 16 with simple atypical endometrial hyperplasia, 48 with complex endometrial hyperplasia, and 31 with complex atypical endometrial hyperplasia. Among the 474 endometrial hyperplasia cases, there were 46 (9.7%) that were classified as EIN. Of these 46 cases, 11(2.9%) were classified as simple endometrial hyperplasia, 1 (6.3%) as simple atypical endometrial hyperplasia, 6 (12.5%) as complex endometrial hyperplasia, and 28 (90.3%) as complex atypical endometrial hyperplasia. EIN was associated with a higher rate of ${\beta}$-catenin positivity than endometrium classified as benign hyperplasia (72% vs. 22.5%, respectively, P<0.001), but a lower rate than endometrial adenocarcinoma (72% vs. 96.2%, respectively, P<0.001). In benign endometrial hyperplasia, high ${\beta}$-catenin expression was noted in the cell membranes, whereas in EIN and endometrial adenocarcinoma high expression was noted in the cytoplasm. In conclusion, EIN is more accurate than the WHO classification for the diagnosis of precancerous lesions of the endometrium.

Background: Abnormal uterine bleeding (AUB) is the most important symptom of endometrial hyperplasia and endometrial curettage (EC) is the gold standard diagnostic procedure. We present the results of patients who underwent EC for AUB and the efficacy of progestin administration in those with endometrial hyperplasia. Materials and Methods: A total of 415 female patients who presented to Duzce Public Hospital in 2011-2012 for AUB and who underwent EC were included. We determined the reasons for AUB, and females with hyperplasia were treated with 10 mg/day medroxyprogesterone acetate for 14 days/month or 160 mg/day megestrol acetate continuously for 3 months. We evaluated the efficacy of progestins for periods of three and/or six cycles by repeating EC. A statistical analysis of specific endometrial causes according to age of presentation was conducted using the chi-square test. Results: Among the 415 females (average age, 53.5 years) followed for 6 months, 186 had physiological changes (44.8%), 89 had simple hyperplasia (21.44%), 1 had atypical hyperplasia (0.2%), 6 had (1.44%) complex hyperplasia, 3 had (0.72%) atypical complex hyperplasia, and 5 had adenocarcinoma (1.2%). Regression rates were 72.7-100%, and the optimum results were observed after 6 months of hormonal therapy. Conclusions: The main cause of AUB was physiological change. Progestin therapy resulted in significant regression even in females with atypical hyperplasia.

Objectives: This study investigated Korean medicine doctors' perspectives on clinical practice patterns in the process of developing Korean medicine clinical practice guidelines for benign prostatic hyperplasia. Methods: A questionnaire was developed for Korean medicine doctors. A total of 323 oriental medicine doctors participated in the survey, which was live for a total of 9 days from September 22, 2022, to September 30, 2022. Results: Regarding awareness of treatments for benign prostatic hyperplasia, 63.8% of respondents showed high awareness of Korean medical treatments. However, items such as diagnostic criteria (17.7%), evaluation methods (17.0%), and Western medical treatments (22.9%) showed low recognition rates. In clinical practice, 76.2% of respondents were found to treat five or fewer patients with benign prostatic hyperplasia per month, and the average treatment period was 1 to 3 months for most at 41.2%. Korean medicine doctors diagnosed benign prostatic hyperplasia based on clinical features. The main interventions used were acupuncture, herbal medicine (prescription medicine), and moxibustion. This study has several limitations because of the low response rate for this survey; therefore, the participants are not representative of all Korean medicine doctors. In addition, because the study was conducted broadly on various topics related to benign prostatic hyperplasia, sufficient quality management was not carried out. Further studies that include a larger sample size and more in-depth studies on benign prostatic hyperplasia are needed. Conclusions: It is necessary to develop appropriate and reasonable Korean medicine clinical practice guidelines for benign prostatic hyperplasia.

Bilateral coronoid process hyperplasia is a rare condition characterized by an enlarged mandibular coronoid process. The painless progressive reduction of a mouth opening is caused by coronoid process impingement on the posterior aspect of the zygomatic bone. Hyperplasia of the bilateral coronoid process leads to the restriction of a mandibular opening consequent to the impingement of the enlarged coronoid process on the temporal surface of the zygomatic bone or with the medial surface of the zygomatic arch. The process has been diagnosed as developmental hyperplasia. Otherwise, the development of the coronoid process may be associated with growth hormone. This paper describes a case of trismus caused by coronoid hyperplasia in an idiopathic short-stature patient who received growth hormone therapy by somatropin injections.

Angiofollicular lymph node hyperplasia is a relatively rare benign lesion. It develops most often in the mediastinum, but also it found in other area of the body, usually where lymph nodes are normally found. There are histologically divided hyaline vascular type, plasma cell type and transitional type. The lesions were discovered most often on routine roentgenograms, and complete surgical excision is the treatment of choice. Recently, the authors experienced a case of angiofollicular lymph node hyperplasia, transitional type, located in the right hilar area. The lesion was removed and the patient is in good condition postoperatively. Now we report this case with review of previously reported literatures.

Neointimal hyperplasia causes vascular access dysfunction in hemodialysis patients with synthetic arteriovenous (AV) grafts. Several studies have reported that paclitaxel- or sirolimus-eluting AV grafts inhibit neointimal hyperplasia and display lower rates of stenosis compared with control grafts. However, there have been few comparative studies of the efficacy of paclitaxel- and sirolimus-eluting grafts. We compared the neointimal hyperplasia of paclitaxel- and sirolimus-eluting grafts. AV grafts were implanted laterally between the common carotid artery and the external jugular vein in 12 female Landrace pigs. The animals were sacrificed six weeks after surgery. The neointimal hyperplasia at the anastomosis sites of the grafts was quantified using the ratio of the intragraft hyperplasia to the graft area (H/G ratio) at the graft-vessel interface. The area of intimal hyperplasia at the venous (paclitaxel 1.06 [0.72-1.56] vs sirolimus 2.40 [1.72-3.0] $mm^2$, P = 0.04) and arterial anastomosis sites (paclitaxel 0.93 [0.57-1.48] vs sirolimus 2.40 [1.72-3.0] $mm^2$, P = 0.04) was significantly different between the two groups. However, the H/G ratios for the venous anastomosis site (paclitaxel 0.25 (0.17-0.38) vs sirolimus 0.38 (0.2-0.66), P = 0.4) and the arterial anastomosis site (paclitaxel 0.19 (0.08-0.39) vs sirolimus 0.41 (0.34-0.50), P = 0.1) did not differ significantly between the groups. In conclusion, there was no significant difference in the inhibition of neointimal hyperplasia by sirolimus- and paclitaxel-eluting AV grafts.

Objectives: This study is to review the effect of Korean medicinal herbs on treatment of benign prostatic hyperplasia induced in rat models, as reported in domestic and foreign journals. Methods: Six electronic databases (EMBASE, PubMed, Oasis, RISS, CENTRAL, and Koreankt) were searched with terms including benign prostatic hyperplasia to identify study reports on treatment of benign prostatic hyperplasia impairment with Korean medicinal herbs. After selecting several studies, the analysis focused on items reflected in the diagnosis of benign prostatic hyperplasia, such as prostate weight, thickness of the prostate epithelium, and prostate specific antigen. Results: Six studies were reviewed. Testosterone propionate was used as a benign prostatic hyperplasia induction material in all the included studies. Cinnamomum verum (CV), Cynanchum wilfordii (CW), Ponciri fructus (PF), Quisqualis indica (QI), Acorus gramineus (AG), and Melandrium firmum (MF) had reduced prostate weight statistically significantly. The QI gave a better response than finasteride in terms of reducing epithelium thickness, and the response was statistically significant. The prostate specific antigen level was lower in the group treated with CV than in the control group. Conclusions: CV, CW, PF, QI, AG, and MF had distinct therapeutic effects. However it is difficult to determine which of these is better by comparing them numerically because the observation items evaluated in a rat model of benign prostatic hyperplasia.

Objective : In benign prostatic hyperplasia, dihydrotestosterone acts as a potent cellular androgen and promotes prostate growth. Inhibiting enzyme $5{\alpha}$-reductase that is involved in the conversion of testosterone to the active form dihydrotestosterone reduces this excessive prostate growth. The mechanism on benign prostatic hyperplasia is substantiating evidence to support the clinical value in the evaluation of therapeutic efficacy. In this study, we investigated the effects of Lygodium japonicum on cyto-pathological alterations and expression of $5{\alpha}$-reductase in the rat model of benign prostatic hyperplasia induced by castration and testosterone treatment. Methods : Sprague-Dawley rats were treated with testosterone after castration for induction of experimental benign prostatic hyperplasia, which is similar to human benign prostatic hyperplasia in histopathological profiles. Lygodium japonicum as an experimental specimen, and finasteride as a positive control, were administered orally. The prostates were evaluated by histopathological changes and testosterone levels. Also, the prostates were observed by hematological alterations of AST, ALT, ${\gamma}$-GTP, BUN and creatinine. Results : The rats treated with Lygodium japonicum showed a diminished range of luminal cell and duct epithelial cell damage. The stromal elements and connective tissue proliferation of Lygodium japonicum treated group as compared to the control group decreased. Conclusions : These findings suggest that Lygodium japonicum may protect the glandular epithelial cells. We concluded that Lygodium japonicum could be a useful remedy agent for treating the benign prostatic hyperplasia.
