Subungual Keratoacanthoma: The Importance of Distinguishing it From Subungual Squamous Cell Carcinoma
2012
Clinical and histopathological study of the oral multifocal melanoacanthoma : a case report
2019
Melanoacanthoma is a blackened mucocutaneous lesion, mainly affecting individuals with dark skin and exhibiting rapid development. Differential diagnosis includes nevus, amalgam tattoo and melanoma. This article reports a case of a 53-year-old white woman, who exhibited multiple blackened lesions on the gingiva and upper lip. After incisional biopsy, the presence of numerous melanin-containing dendritic cells distributed throughout the epithelial thickness, which were S-100 (+), were observed microscopically. Final diagnosis was multifocal oral melanoacanthoma. Follow-up for 28 months has shown appearing of more lesions in gingiva and upper lip. Therefore, the importance of differential dia…
Oral pigmented lesions: clinicopathologic features and review of the literature
2012
Diagnosis of pigmented lesions of the oral cavity and perioral tissues is challenging. Even though epidemiology may be of some help in orientating the clinician and even though some lesions may confidently be diagnosed on clinical grounds alone, the definitive diagnosis usually requires histopathologic evaluation. Oral pigmentation can be physiological or pathological, and exogenous or endogenous. Color, location, distribution, and duration as well as drugs use, family history, and change in pattern are important for the differential diagnosis. Dark or black pigmented lesions can be focal, multifocal or diffuse macules, including entities such as racial pigmentation, melanotic macule, melan…
Automated macular choroidal thickness measurement by swept-source optical coherence tomography in pseudoxanthoma elasticum
2016
Introduction Pseudoxanthoma elasticum (PXE) typically involves elastic fibers in blood vessels and Bruch membrane. Our purpose was to analyze retinal and choroidal macular thickness in patients with angioid streaks due PXE compared with a control group. Methods Best-corrected visual acuity (BCVA), axial length (AL), and macular swept-source optical coherence tomography were obtained. Automated segmentations of the retina and the choroid were used to obtain the corresponding thickness values. An age, gender and AL matched control group was used to compare the thickness values. Results Twelve eyes of 6 patients were included. The mean BCVA was 0.68 ± 0.29 versus 1.0 in controls (p < 0.001). T…
[Pseudoxanthoma elasticum (Grönblad-Strandberg syndrome) and rheumatoid arthritis].
1990
A 72-year-old woman, not previously known to have coronary heart disease, was admitted to hospital with an acute anterior wall myocardial infarction. The history revealed that, when about 40 years of age, a coarse skin-fold and yellowish-white xanthoma-like efflorescences had been noted around her umbilicus, the inguinal regions and axillae. These changes subsequently developed into a pathognomonic picture of pseudoxanthoma elasticum (PE), which was a significant factor in the myocardial infarction. At the age of 69 years, rheumatoid arthritis (RA), stage II after Steinbrocker, had been diagnosed on the basis of morning stiffness, symmetrical arthritis in more than three joint regions and t…
Oral melanoacanthoma and oral melanotic macule: a report of 8 cases, review of the literature, and immunohistochemical analysis.
2007
Oral melanoacanthoma (MA) is a rare, benign pigmented lesion, similar to cutaneous MA, characterized by hyperplasia of spinous keratinocytes and dendritic melanocytes. The pathogenesis of oral MA remains uncertain, although its clinical behavior is suggestive of a reactive origin. The most common intraoral sites are the buccal mucosa, lip, palate and gingiva. The average age of presentation is 28 years, mainly in blacks, with a strong female predilection. The oral melanotic macule (MM) is a small, well-circumscribed brown-to-black macule that occurs on the lips and mucous membranes. The etiology is not clear and it may represent a physiologic or reactive process. The average age of presenta…
Funktionaalisia a posteriori virhearvioita Uzawan tyyppisille menetelmille kokoonpuristumattomien virtausten tapauksessa
2012
Stokesin yhtälöllä voidaan kuvata nesteiden ja kaasujen liikettä, jos liike on yksiulotteista tai hidasta. Stokesin yhtälö on yksinkertaistettu ja linearisoitu versio Navier-Stokesin yhtälöistä. Tässä tutkielmassa keskitytään kokoonpuristumattomiin ja viskoottisiin nesteisiin ja kaasuihin. Kokoonpuristumattomuus tarkoittaa sitä, että nesteen tai kaasun tiheys ei muutu ajan suhteen. Viskoottisuus taas tarkoittaa sitä, että nesteillä ja kaasuilla on sisäistä kitkaa, joka muodostuu, kun aineen osaset liikkuvat toistensa suhteen. Vaikka osittaisdifferentiaaliyhtälöiden tutkimus on edennyt viime vuosisadalla hyvinkin nopeasti, on analyyttisen ratkaisun löytäminen vaikeaa tai lähes poikkeuksetta …
Necesario, pero no deseado. Las advertencias de Thomas Hobbes sobre los peligros de la multitud, el populismo y la democracia
2016
The purpose of this article is to analyse Hobbes’s understanding of democracy. The first part of the article analyses the role of democracy in the social contract. It aims to show how there exists a democratic element at the beginning of the process of social contract, in which the multitude is transformed into a people. However, after the first social contract is made, Hobbes aims to reduce the power of the people by leading the process of social contract on to another level, on which the power of the people is assigned to a representative of the sovereign power, for example a monarch. The second part of the article aims to explain the practical reasons, provided by Hobbes in different par…
Federaliści i rozłam między klasycznością a modernością
2014
The article shows how the classical political thinking, based on civic virtues, and modernist thinking, based on individualism and self-interest, formed the basis of the U.S. Constitution. The Founding Fathers did not realize the full extent of the rift between classicism and modernity. When, as a result of intellectual discussions and practice of social life, this divide began to become more and more obvious, there has been a transition from the classical to the modernist paradigm in American politics. However, the dispute between classicism and modernity still continues and takes on new forms. On the one hand, contemporary political thinking is seen as a triumph of modernism, in which the…
O duchowym przywództwie politycznym. Polityka duchowa jako droga dla rozwoju przyszłej Europy
2022
Duchowe przywództwo polityczne odnosi się do sztuki rządzenia państwem, która uwzględnia pełny i wszechstronny rozwój osobowy człowieka, umożliwia obywatelom samorealizację i w ten sposób zaspakaja ludzkie dążenie do osiągnięcia doskonałości moralnej i intelektualnej, osiągającej swój najwyższy stopień rozwoju w świętości jako łączności z doskonałością Boga. Jego celem jest szczęśliwe społeczeństwo, w którym każdy ma możliwość samorealizacji, a jednocześnie szanuje samorealizację innych. Wspiera harmonię społeczną, która wynika ze współdziałania między różnymi grupami w obrębie społeczeństwa oraz jest alternatywą dla dzisiejszej dysharmonii będącej pokłosiem toczącego się konfliktu politycz…
