Multidisciplinary approach to hepatic metastases of intracranial hemangiopericytoma: A case report and review of the literature
No full textHemangiopericytoma is a rare primary tumor originating from Zimmerman's pericytes, with significant metastatic potential. Hepatic metastatic disease requires an aggressive approach by a multidisciplinary team of dedicated oncology specialists, to prolong survival in selected patients. We report on a patient with recurrent hepatic metastases of grade II intracranial hemangiopericytoma 5 years after initial treatment, managed by a stepwise combination of liver resection, radiofrequency ablation, and transarterial embolization. Although metastatic disease implies hematogenous dissemination, long-term survival after liver resection has been reported and major hepatectomies are justified in patients with adequate local control. Liver resections combined with transarterial embolization are highly recommended, due to hypervascularity of the tumor. © 2015 Dimitrios K. Manatakis et al

Dimitrios Tsamis Karatasos : a symbol of Greek, Serbian and Bulgarian friendship
No full textTwo Serbian texts extol the contribution of Dimitrios Tsamis Karatasos to the Balkan joint effort to throw off the Ottoman yoke. These texts are analysed by the author within the historical framework of their period, so that the man’s personality and work may be accurately evaluated from a fresh viewpoint. More specifically, the author conducts a research on the tombstone of Dimitrios Tsamis Karatasos, which he discovered himself at Naoussa, and the octet engraved on it, which is also published here. The work is illustrated by seven plates, of which four have not been published previously

Association of Baseline Neutrophil-to-Lymphocyte Ratio with Clinicopathological Characteristics of Papillary Thyroid Carcinoma
No full textObjective. To investigate the potential association of neutrophil-to-lymphocyte ratio (NLR), a surrogate systemic inflammatory biomarker, with clinical and pathological characteristics of papillary thyroid cancers. Methods. 205 patients with papillary carcinoma were identified from the institutional thyroid cancer database between 2006 and 2015 (55 males, 150 females, mean age 51.2 ± 14.7 years). NLR was calculated as the absolute neutrophil count divided by the absolute lymphocyte count, based on the preoperative complete blood cell counts. Results. NLR was significantly higher in carcinomas with extrathyroidal invasion (2.74 ± 01.24 versus 2.39 ± 0.96, p=0.04) and bilateral (2.67 ± 1.15 versus 2.35 ± 0.96, p=0.03) and multifocal tumours (2.65 ± 1.08 versus 2.29 ± 0.96, p=0.01), as well as lymph node-positive tumours (3.12 ± 1.07 versus 2.41 ± 1.02, p=0.03). On the other hand, NLR values were not associated with gender, age, tumour size, histologic subtype, the presence of thyroiditis, and TNM staging. Conclusions. As an index of inflammation, NLR is inexpensive, readily available, and easy to extract from routine blood tests. We found increased NLR values in papillary carcinomas with poorer histopathological profile and more aggressive clinical behaviour. Whether this systemic inflammatory response, as expressed by the NLR, represents the inflammatory microenvironment leading to tumourigenesis, or is a tumour-associated phenomenon, remains to be elucidated and warrants further study. © 2017 Dimitrios K.

Diagnostic Accuracy of Preoperative Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios in Detecting Occult Papillary Thyroid Microcarcinomas in Benign Multinodular Goitres
No full textObjective. To investigate the diagnostic accuracy of neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios in detecting occult papillary thyroid microcarcinomas in benign, multinodular goitres. Methods. 397 total thyroidectomy patients were identified from the institutional thyroid surgery database between 2007 and 2016 (94 males, 303 females, mean age 53 ± 14.5 years). NLR and PLR were calculated as the absolute neutrophil and absolute platelet counts divided by the absolute lymphocyte count, respectively, based on the preoperative complete blood cell count. Results. NLR was significantly higher in carcinomas and microcarcinomas compared to benign pathology (p=0.026), whereas a direct association could not be established for PLR. Both NLR and PLR scored low in all parameters of diagnostic accuracy, with overall accuracy ranging between 45 and 50%. Conclusions. As surrogate indices of the systemic inflammatory response, NLR and PLR are inexpensive and universally available from routine blood tests. Although we found higher NLR values in cases of malignancy, NLR and PLR cannot effectively predict the presence of occult papillary microcarcinomas in otherwise benign, multinodular goitres. © 2018 Dimitrios K.

The Exemplary Life of Dimitrios Vikelas (1835-1908)
No full textThis paper describes the "satisfying curve" of Dimitrios Vikelas' life journey, starting from Syros in 1835, moving via Constantinople, Odessa, and Syros again, to London, Paris and finally Athens. It explores Vikelas' multiple aspects, as merchant, writer, traveller, lecturer and essayist, Olympic founder, educationalist, book collector and philanthropist, all of which were united in the public-spirited man of letters (logios). It sets Vikelas in the context of the Greek commercial diaspora, the world of the London expatriate Greek community, and the dynamic society of late nineteenth-century Athens, beginning in the 1870s to act as a magnet to Greek expatriates. The author stresses two qualities of Vikelas: his belief in the idea of a progressive Greek state marked by advances in education, culture, tourism and standards of public life; and the self-awareness and experience which inform his autobiographical writings, not only his memoir My Life but also his last such work, The War of 1897
