The purpose of this study is to study the inner meaning and formative with distorted and atypical Informel image, body image expressed in modern fashion. Method of the study is as follow. The study method examined philosophy of art 19th century?in order to consider interconnections between social and cultural characteristics of expressionistic abstract art, a form of Informel and changed physical style. Based on this method, the Informel image that appeared in the plastic arts in terms of artistic significance and aesthetic value was examined. Based on the above discussion on modern fashion Informel images were expressed in any formative characteristics were considered. The results of this study are as follows. Contingencies through the spontaneous act of art to transcend the image of atypical lines formed elements of coincidence, was developed. Liberation was expressed from liberation of physical boundaries and created outward expansion of the free formative. Atypical was organic forms pursuing spontaneous plasticity and diversity, and appeared in the form of distortion and deformation.

Atypical hemolytic uremic syndrome (aHUS) is an extremely rare and life-threatening disorder. Typical HUS is often caused by Shiga toxin-positive Escherichia coli, while aHUS is caused by dysregulation of the alternative pathway of the complement system in association with genetic abnormalities or development of autoantibodies. Eculizumab, a humanized anti-complement 5 monoclonal antibody, is recommended for the treatment of aHUS, but its long-term safety and efficacy in pediatric patients remain under review. In this paper, we report a pediatric case of aHUS with anti-complement factor H autoantibodies, who was treated successfully with eculizumab.

Liposarcoma is a malignant tumor that occurs in adipocytes, accounting for 5% of all sarcomas. Generally, it has no symptoms and it occurs in any parts of the body. There are various types of liposarcoma. Of these, 40-45% are known as highly differentiated liposarcoma, and highly differentiated liposarcoma is also referred to as atypical lipomatous tumor. We report a case of an atypical lipomatous tumor on the left neck.

About 6.7% mortality was reported in a starry flounder (Platichthys stellatus) aquaculture farm in 2022. Most of the diseased fish showed a loss of pectoral fin, hemorrhages on muscle and gills, pale gills, enlarged spleen, and nodules on kidney. Parasites, fungi or viruses (viral hemorrhagic septicemia virus and hirame novirhabdovirus) were not detected from diseased fish. However, numerous bacteria were isolated from liver, spleen and kidney. Nucleotide sequences of the A-protein-encoding virulence array protein gene (vapA) of the bacteria showed 99.93% identity with Aeromonas salmonicida subsp. masoucida. This study is the first report of isolation of atypical A. salmonicida in cultured starry flounder in Korea.

목 적 : 양성 뇌수막종에 비하여 이형성 및 악성 뇌수막종이 나쁜 임상적인 예후 및 양상을 보이는 것은 잘 알려져 있으나, 양성 뇌수막종에 있어서 각각의 병리조직학적 아형에 따른 생물학적 양상의 차이에 대해서는 잘 알려지지 않거나 일부 논란이 되고있다. 본 연구에서는 이형성 뇌수막종 및 양성 뇌수막종의 각각의 병리조직학적 아형에 따른 증식능의 차이여부를 알아보고자 PCNA와 Ki-67표지지수를 분석하였다. 방 법 : 본원에서 뇌수막종으로 수술을 시행하여 얻은, 재발을 보여 재수술을 시행한 2례를 포함하여, 파라핀에 포매시킨 27개의 조직을 대상으로 병리학적인 증식능을 분석하기 위해, PCNA에 대한 단일항체 및 MIB-1 단일항체를 이용한 면역조직화학적 염색을 시행하였다. 조직학적 분류상 meningothelial type이 8례, transitional type이 9례, fibroblastic type이 5례였으며, 이형성 수막종이 5례였다. 결 과 : PCNA표지지수의 평균값은 양성 수막종에서 meningothelial type이 $4.82{\pm}5.10%$, transitional type이 $9.01{\pm}4.25%$, fibroblastic type이 $5.66{\pm}5.32%$를 보였으나 이형성 수막종에서는 $27.62{\pm}19.67%$의 높은 지수를 나타냈고, Ki-67 표지지수의 평균값은 양성 수막종의 아형에서 각각 $0.43{\pm}0.85%$, $0.44{\pm}1.08%$, $0.24{\pm}0.18%$를 보이고, 역시 이형성 수막종에서는 $0.84{\pm}0.59%$의 높은 지수를 보였다. 즉, 양성 수막종에서 각각의 아형에 따른 PCNA 및 Ki-67 표지지수는 통계학적으로 의미있는 차이는 없었으나(p>0.05), 이형성 수막종에서는 의미있는 높은 표지지수를 보여(p<0.05) 양성 수막종에서 보다 높은 증식능을 보임을 알 수 있었다. 결 론 : PCNA 및 Ki-67 표지지수를 이용한 증식능의 비교결과, 양성 뇌수막종에서는 각각의 아형에 따른 생물학적 양상이나 예후는 차이가 없을것으로 생각되나, 이형성 수막종에서는 높은 증식능을 보여 이에 대한 예후를 예상할 수 있을것으로 생각되며, 또한 이러한 표지지수가 병리조직학적으로 양성과 이형성의 감별에 많은 도움이 될것으로 사료된다.

Purpose: To study the prevalence of CIN2+ diagnosis in women with atypical Papaniculoau (Pap) smears to suggest appropriate management option for Thai health care. Materials and Methods: Data from all patients with liquid based cytology with human papillomavirus (HPV) testing between May 2013 - May 2016 were collected from medical records. Women with atypical cervical Pap smears were recruited. Results for age, HPV testing, HPV 16, 18, 45 and other genotypes tested, colposcopic examination and histopathological assessment were all collected. Atypical smears were defined as atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells cannot be exclude high grade squamous intraepithelial lesion (ASC-H). Results: A total of 2,144 cases were recruited. Twenty six women with ASC-US on cytology had high risk (HR) HPV detection while eight cases with ASC-H had HR-HPV (40.0% VS 72.7%, p=0.005). Among the 26 women with ASC-US cytology and positive HR-HPV, HPV type 16 (n=8, 30.8%), type 18 (n=1, 3.8%), type 45 (n=1, 3.8%) and other HPV types (n=17, 65.4%) were found. Eight women with ASC-H and positive HR-HPV demonstrated type 16 (n=6, 75%) and other HPV types (n=2, 25%). Fifty seven women with ASC-US had normal colposcopy, CIN1 and CIN2+ at percentages of 80.7 (46/57), 14.0 (8/57) and 5.3 (3/57), respectively. In the ASC-H group, 7 out of 10 women had normal colposcopy and three (30%) had CIN2+ results. Conclusions: In women with ASC-US cytology, immediate colposcopy is highly recommended. HPV testing can be performed if colposcopy is not an available option because there was high prevalence (5.3%) of CIN2+ in our findings. ASCCP recommendations for ASC-H that colposcopy should be performed on all ASC-H cases regardless of HPV result are thereby supported by the findings of this investigation.

피뿔고둥, Rapana venosa의 정소소엽 내에서 정자형성과정 중에 생성되는 정상적인 생식세포의 발달과 함께 섞이어 일정 시기에만 출현하는 비정형세포들을 미세구조적으로 관찰하였고, 또한 정소 발달단계에 따른 저정낭 내층 상피세포들의 주기적 변화를 조직학적 관찰에 의해 조사하였다. 생식세포의 발달단계는 정원세포기, 정모세포기, 정세포기, 정자기로 나누어지며, 정모세포기는 다시 제1 정모세포기와 제2 정모세포기로 세분할 수 있어, 총 5 단계로 구분할 수 있었다. 정상적인 웅성생식세포들의 분화와 발달과정은 다른 복족류 종들과 유사하였다. 정자는 길이가 대략 $50{\mu}m$ 정도이었다. 정자의 미부 편모의 악소님 (axoneme) 은 주변에 9쌍의 미세소관들과 중앙에 1쌍의 미세소관들로 구성되어 있다. 즉, 9+2 구조를 이루고 있다. 특히, 대형 복족류 중 뿔소라과 피뿔고둥의 경우는 예외적으로 다른 이매패류나 두족류 등과 달리 정소소엽 내에서 정자형성과정 중에 정상적인 생식세포들 사이에서 총 4종 (Type IA, IB, Type IIA, IIB) 의 비정형세포들 (atypical cells) 이 함께 출현하는 특징을 보이고 있는데, 이러한 현상은 대형 복족류의 단지 소수의 종들에 한하여 출현하는 예외적인 특이한 현상이라 할 수 있다. 그러나 비정형세포들은 저정낭의 여러 단계 중 내층 상피세포들 내에서는 발견되지 않았다. 추측컨대 몇 가지 비정형세포들은 리소좀-모양의 공포들이나 리소좀-모양의 소체들을 가지는데, 이들은 정소소엽 내에서 붕괴나 그 자신들의 흡수에 관여하는 것으로 추정된다. 상당량의 정자들이 정소소엽 내에서 형성되어, 그들의 일부는 7월 말까지 정소에서 저정낭으로 이동된다. 교미 성기는 6-7 월 사이이었다. 피뿔고둥 저정낭 발달단계의 주기적 변화는 (1) S-1 단계 (휴지단계), (2) S-II 단계 (축적단계), 그리고 S-III 단계 (배정단계) 의 3 단계로 구분되었다.

Objective : The primary objective of this study was to identify predicting factors for local control (LC) of atypical meningioma, and we validated them with comparing the predicting factors for recurrence-free survival (RFS). We also examined the rate of LC after surgical resection with or without adjuvant treatment and RFS. Methods : Clinical and radiological records of patients with atypical meningiomas diagnosed at two institutes from January 2000 to December 2018 were reviewed retrospectively. Histopathological features were also reviewed using formalin-fixed paraffin embedded samples from pathological archives. Results : Of the 99 atypical meningiomas eligible for analysis, 36 (36.4%) recurred during the follow-up period (mean, 83.3 months; range, 12-232 months). The rate of 3-year LC and 5-year LC was 80.8% and 74.7%, respectively. The mean time-to-recurrence was 49.4 months (range, 12-150). The mean RFS was 149.3 months (95% confidence interval, 128.8-169.8 months) during the mean follow-up duration of 83.3 months (range, 12-232 months). Multivariate analysis using Cox proportional-hazard regression model showed that the extent of resection (hazard ratio [HR], 4.761; p=0.013), Ki67 index (HR, 8.541; p=0.004), mitotic index (HR, 3.275; p=0.044), and tumor size (HR, 3.228; p=0.041) were independently associated with LC. These factors were also statistically associated with RFS. In terms of radiotherapy after surgical resection, the recurrence was not prevented by immediate radiotherapy because of the strong effect of proliferative index on recurrence. Conclusion : The present study suggests that the extent of resection, proliferative index (according to Ki67 expression) and mitotic index, and tumor size are associated with recurrence of atypical meningiomas. However, our results should be further validated through prospective and randomized clinical trials to overcome the inborn bias of retrospective nature of the study design.

Paratesticular liposarcoma is a very rare tumor that is typically reported as isolated cases of or as components of larger studies of liposarcomas. Image findings are similar to those of other anatomic sites, but in less-common sites, their appearance may be less familiar, and they may be mistaken for other pathologies. In addition, atypical image findings of liposarcoma make diagnosis more difficult. Herein, we report on the case of a 45-year-old male patient who presented with a painless, palpable mass in the right scrotum. The patient was diagnosed with paratesticular liposarcoma by excisional biopsy.
