BACKGROUND: The reproducibility in grading a cervical intraepithelial neoplasia (CIN) are not perfect. The aim of this study was to assess the value of the immunohistochemical expression of p63 and the other biomarkers for grading a CIN (dysplasia and in situ carcinoma), and diagnosing invasive carcinomas. METHODS: Sixty six cervical specimens were immunostained with the monoclonal antibodies against p63, Ki-67, p27Kip1, and p53 to determine the localization. RESULTS: The p63 positive cells are well linked with squamous cell maturation and the degree of dysplasia. In mild dysplasia, the p63 positive cells were localized to the basal and parabasal cells, which gradually extended into the middle and upper layers in moderate and severe dysplasia. p63 expression was strong in immature squamous epithelium and invasive squamous cells, but was constantly absent in an adenocarcinoma. The Ki-67 positive cells were scattered from the parabasal cells to the superficial cells in accordance with the degree of dysplasia. p27Kip1 expression was noted in the intermediate cells in the normal cervix. In CIN, the p27Kip1 positive nuclei tended to extend to the basal cells, but it showed no diagnostic consistency in an invasive carcinoma. p53 expression was also variable. CONCLUSION: p63 is a useful diagnostic adjunct for grading CIN as well as for detecting microinvasion and squamous differentiation in invasive carcinoma. However, immunohistochemical expressions for the p27Kip1 and p53 have no correlation with the grade of CIN and squamous cell carcinoma.

Purpose: To report the availability of optical coherence tomography angiography (OCTA) when diagnosing type 1 and type 2 choroidal neovascularization (CNV) associated with age-related macular degeneration. Methods: We conducted a retrospective chart review of 63 eyes of 59 patients who visited the outpatient clinic from April 2018 to January 2020 with treatment-naïve type 1/2 CNV associated with age-related macular degeneration. The CNV was diagnosed through fluorescein angiography and indocyanine green angiography on the appearance of hyperfluorescence and leakage at the late phase. The CNV type was classified by location using OCT. These results were compared with those of automatic and manual segmentations via OCTA. Results: Of the 63 eyes, 45 eyes showed type 1 CNV and 18 eyes indicated type 2 CNV. Using the automatic segmented display of OCTA, type 1 CNV was identified in 29 of 45 eyes and type 2 CNV was confirmed in 17 of 18 eyes. In addition, when manual segmentation was performed, type 1 CNV was found in 41 of 45 eyes and type 2 CNV in 18 of 18 eyes. The sensitivity of diagnosis of type 1 CNV using only automatic segmentation in OCTA was 64.44%; the sensitivity increased to 91.11% when additional manual segmentation was performed (p < 0.001). For type 2 CNV, the sensitivity was 94.44% using automatic segmentation in OCTA and 100% with additional manual segmentation (p = 1.000). Conclusions Automatic segmentation of OCTA and OCT analyses enabled diagnosis of type 1 and type 2 CNV associated with age-related macular degeneration. The diagnosis accuracy or type 1 CNV improved significantly when manual segmentation was added.

PURPOSE: The purpose of this study was to present methods and results for the modified Phemister operation, with a suture anchor added for augmentation of the conoid ligament in cases of acute dislocation of the acromioclavicular joint. MATERIALS AND METHODS: We evaluated 14 cases of acute dislocation of the acromioclavicular joint. This included 11 cases of Rockwood type 3, and 3 cases of type 5. The mean age of patients was 45.2 years. We operated on them using an anchor for augmentation of the conoid ligament in the modified Phemister operation. The average follow-up period was 14 months and post-operative clinical analysis was conducted using the Weitzman classification, VAS Score, Constant Score and KSS Score. RESULTS: According to Weitzman scores, 13 cases were evaluated as excellent, and one case was good. They had mean joint ranges of forward elevation of 170.7degrees, lateral elevation of 166.4, external rotation of 68.2, and internal rotation to the level of T7. The mean VAS Score was 1.9, mean Constant Score 90.8, and the mean KSS Score 91. Radiologic analysis indicated that all cases had a good result. CONCLUSION: The modified Phemister operation with a suture anchor added for augmentation of the conoid ligament is very effective clinically in acute dislocations of the acromioclavicular joint.

OBJECTIVES: We compared the characteristics of the pain threshold and pain experience between demented group and non-demented group. METHODS: This study was part of Gangwon projects for early detection of dementia in 2010. We recruited 8302 local resident ages over 65 years old. Of theses, 1259 people who scored low MMSE were selected and 365 of them completed CERAD-K(Consortium to Establish a Registry for Alzheimer's disease). Finally, 90 in non-demented group and 57 in demented group(mild to moderate Alzheimer's disease) were analyzed. Pain threshold was experimentally measured by pressure algometer and we investigated the pain experience, by Brief pain inventory (BPI), a self-report test. RESULTS: In the demographic characteristics, there are more female, higher ages, lower education in the demented group. There was no significant difference between the two groups in the pain threshold. On the BPI results, 'shoulder pain', 'the number of pain' and 'interference of working' were significantly more prevalent in non-demented group. However, there are no significant differences between the groups in the 'pain severity', 'prevalence of pain' and 'pain treatment'. CONCLUSIONS: Demented group report less pain experience but, still perceived pain. It support previous studies that patient with dementia have increased pain tolerance but preserved pain threshold. Thus, active pain assessment and treatment for patients with dementia is needed.

OBJECTIVE: The involvement of IGF system in hyperandrogenism and abnormal follicular development is controversial. This study is to assess whether IGF system contribute to it in the women with polycystic ovary(PCO). METHODS: Baseline serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), testosterone (T), androstenedione (ADD), prolactin, thyroid stimulating hormone (TSH), free insulin-like growth factor(IGF)-I, free IGF-II, insulin-like growth factor binding protein(IGFBP)-1, and IGFBP-3 were measured in twelve healthy regularly cycling volunteers and forty-two women with PCO then, the changes of baseline serum levels were evaluated after laparoscopic ovarian electrocauterization in nine PCO patients. In addition, the expression pattern of IGF-I and IGF-II was examined in the ovary of control and PCO group. RESULTS: Baseline levels of LH, ADD, free IGF-II, and IGFBP-3 were significantly higher in PCO group. However, there were no significant differences in the levels of free IGF-I and IGFBP-1, although free IGF-I showed decreasing tendency in PCO group. And there was a significant positive correlation between the LH and free IGF-II level in the PCO(P=0.011, r2=0.3899), but not in the control. After ovarian electrocauterization, LH, T, and ADD levels decreased, and free IGF-I and IGFBP-3 level increased. While free IGF-II and IGFBP-1 level showed no significant changes. In the ovary, expression of both IGFs showed similar pattern in normal and PCO ovaries. CONCLUSIONS: The elevated IGFBP-3 level may alter the bioavailability of IGF(s) in the PCO. The change in IGF-I level and resumption of ovulation after electrocauterization, suggest a possible role of IGF system in the impairment of follicular development in the PCO.
