Despite this, the Ki-67 index is not recommended for routine use in newly diagnosed breast carcinomas. Material and Methods: A total of 164 invasive breast carcinomas were stratified into the intrinsic molecular subtypes based on estrogen receptor, progesterone receptor (PR), HER2, and Ki-67 immunostaining. We studied the distribution of Ki-67 among the molecular subtypes and correlated it with clinicopathologic parameters. Furthermore, the change in the Ki-67 index with tumor size, grade and lymph node (LN) status among the molecular subtypes was examined. Results: As a continuous variable, the median Ki-67 did not show significant differences with the clinicopathological variables. At a cutoff ≥14%, it correlated significantly with the mitotic index. At a cutoff ≥20%, it additionally correlated with the PR status. The median Ki-67 level varied significantly between luminal A and all other molecular subtypes. The median Ki-67 level in T1/T2 tumors compared to T3/T4 tumors was slightly higher in luminal B HER2+, slightly lower in HER2 enriched, and nearly similar among luminal A, triple negative and luminal B HER2-subtypes, yet without statistical significance. The median Ki-67 was lower in G1/G2 compared to G3 tumors in all-except luminal B HER2-positive subtype but without statistical significance. The Ki-67 distribution change between N0/N1 and N2/N3 cases among the molecular subtypes was significant. Conclusions: The impact of Ki-67 as a proliferation marker on the biological behavior of breast carcinomas is context dependent, and its clinical utility increases when interpreted in combination with other prognostic markers in the context of the molecular subtypes. Further studies, on larger sample sizes are recommended to unravel how the molecular types can affect the relation between Ki-67 and clinicopathological characteristics, particularly the LN status.","PeriodicalId":91320,"journal":{"name":"Journal of interdisciplinary histopathology","volume":"6 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70819067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breakdown of the physiological astrocyte-endothelial cell relationship occurs in adult metastatic and primary brain tumors. However, the astrocyte-endothelial cell relationship has not been studied in pediatric tumors. Materials and Methods Utilizing specimens from cases of pilocytic astrocytoma (n = 5), medulloblastoma (n = 5), and low-grade diffuse astrocytoma (n = 1), immunofluorescence were performed using primary antibodies against CD31, glial fibrillary acidic protein (GFAP), and aquaporin 4 (AQ4). Clinical, magnetic resonance imaging, operative, and histopathological findings were analyzed. Results Strongly-enhancing areas of medulloblastoma exhibited complete BBB breakdown with sparse GFAP and AQ4 staining around CD31-positive vessels. Moderately enhancing regions of pilocytic astrocytomas exhibited regions of intact BBB and vasculature surrounded by dense GFAP staining but reduced and disorganized AQ4 staining, suggesting tumor cells could not fulfill physiological BBB support. Non-enhancing low-grade diffuse astrocytoma demonstrated intact BBB with intense peri-microvasculature GFAP and AQ4 staining. AQ4 stained so strongly that AQ4 visualization alone delineated CD31-positive vessels. Conclusion Taken together, BBB breakdown in pediatric tumors corresponds to a loss of normal endothelial cell-astrocyte foot process relationships. Further development of pharmaceutical agents capitalizing on this disrupted BBB is warranted in medulloblastoma and pilocytic astrocytoma. However, BBB integrity remains a challenge in treating low-grade diffuse astrocytoma before progression toward secondary glioblastoma.","PeriodicalId":91320,"journal":{"name":"Journal of interdisciplinary histopathology","volume":"4 1","pages":"29 - 33"},"PeriodicalIF":0.0,"publicationDate":"2016-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70819285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grossly, an 8 mm nodule was well circumscribed, soft, and it had gray cut surface. Histologically, typical features of EHE were seen, such angiocentric localization, epithelioid cytomorphology with mild atypia, myxohyaline stromal matrix, a few slit-like vascular channels, and isolated vacuolated cells. In addition, the stroma contained numerous spindle cells resembling myoblasts or myofibroblasts. They showed, besides scattered positivity for vascular markers, focal positivity for CALP and diffuse strong expression of alpha-smooth muscle actin and pancytokeratin AE1/AE3. This observation of numerous actin+/CK+cells is unusual.

There is a debate in the diagnosis of IIMs and up until now, about 12 criteria systems have been proposed. Some of the criteria systems have been used widely such as Griggs et al.’s proposal for IBM. Clinical findings, autoantibodies, enzymes, electrophysiological, and muscle biopsy findings are diagnostic tools. Because of diseases’ complexity, none of the findings are diagnostic alone.

Objective: This study was aimed at investigating the activities of C. papaya on the histo-architecture of some organs. Materials and Methods: About 20 Wistar rats were randomly divided into 4 groups of 5 each and received tap water, 2.5, 5, and 7.5 g/kg of ethanolic extract of C. papaya PO once a day for 14 days after which biochemical analyses was performed on the blood samples. The tissues were examined histologically. Results: Albumin was significantly increased (37.6 ± 2.70) in Group B (5 mg/kg) when compared with the control (32.4 ± 2.30). AST decreased significantly in all the treatment groups (68 ± 1.58, 87.4 ± 403, and 89 ± 1.58) when compared with the control (93.6 ± 1.14). ALT decreased in all groups but was significant in Group C (7.5 mg/kg) 22.8 ± 2.16 when compared with the control (30 ± 2.12).

Na+ and K+ significantly decreased in Groups C and B, respectively; there was no significant difference in other groups and electrolytes. There was increased level of both packed cell volume and hemoglobin significantly. Histologically, there were no tissue alterations in all the treatment groups.
