Tumoren der Ceruminaldrüsen

1987

Tumours originating from the ceruminous glands can be classified into five types: adenomas, adenocarcinomas, adenoid-cystic carcinomas, pleomorphic adenomas and mucoepidermoid carcinomas. The diagnosis is based on histological findings and can be quite difficult if the tumour status has to be determined. Classification into one of the five types of tumours may be facilitated at times by studying the clinical pattern. Three case reports are quoted as examples to illustrate that neoplasias originating from the ceruminous glands can assume considerable proportions and must be considered in differential diagnosis when assessing space-occupying growths in the soft tissue of the neck. Whereas pro…

An observational study of the frequency of supernumerary teeth in a population of 2000 patients

2007

An evaluation is made of the epidemiological characteristics of supernumerary teeth, with an analysis of the associated clinical-eruptive complications. A longitudinal observational study was made of 2000 patients, with the documentation of demographic data, the presence of supernumerary teeth, their location, mechanical accidents and the presence of associated pathology. The presence of supernumerary teeth was recorded in 1.05% of the study subjects (mean age 20.2 years), with a greater frequency in males. The most frequent location was in the upper maxilla (79.2%), fundamentally in the retromolar zone and at premaxillary level. The presence of mechanical accidents was the most frequent co…

Sebaceous adenoma of the parotid gland

2006

Los tumores de las glándulas salivales constituyen un área importante de la patología oral y maxilofacial. La mayor parte de las neoplasias glandulares salivales son benignas, representando las malignas entre el 15 y el 32% del total. La localización más común de estas entidades es la glándula parótida, en la que asientan hasta el 80% de todos los casos. En este artículo se presenta un caso de adenoma sebáceo salival, de localización parotídea. El tumor, formado por células epiteliales que tapizan conductos, exhibe amplias áreas de diferenciación sebácea y zonas con metaplasia oncocítica. El patrón histológico es predominantemente quístico, observándose cavidades rellenas con material sebác…

Prostatic adenocarcinoma with mandibular metastatic lesion : case report

2007

Metastatic lesions of primary tumors, which originate in different parts of the body, comprise almost 1 % of different types of oral cancers. These lesions can affect either bones or soft tissues in the maxillofacial region. Whenever the maxillofacial area is affected, the most common location is in the molar region of the mandible. The clinical presentation of mandibular metastasis follows a clinical pattern characterized by irradiated dental pain in the third molar region. The most frequent sign is parethesia of the area innervated by the mandibular alveolar dental nerve. Differential diagnosis and treatment of these patients can be extremely difficult because there a number of pathologic…

A case report of coexistence of a sialolith and an adenoid cystic carcinoma in the submandibular gland

2006

Ôhe occurrence of sialoliths in the submandibular gland is 80% due to the specific anatomy of both the gland and its duct. The diagnosis is rather easy because of the obvious clinical signs of the entity. Imaging studies are always necessary in order to treat the patient as effectively as possible. The stones do not tend to occur within the gland as frequently as in the respective duct. The coexistence of sialoliths and malignant tumors is extremely rare. A 70-year-old woman with intraparenchymal stone was operated in our ENT department. In addition to the sialolith the pathological examination revealed the existence of an adenoid cystic carcinoma (ACC), that extended to the neighboring ske…

The Role of Leadership in Complex Strategic Networks: Enabling Effect Versus Emergence

2013

In today's knowledge-based economy, the sources of competitive advantage lie more and more in webs of interactions among a variety of actors (such as firms, universities, research organizations, government institutions and so on), that over time originate the emergence of strategic networks. The paper aims to shed light on the determinants of network interaction and the ensuing processes of knowledge and resource transfer and circulation, on which the networkbased sources of competitive advantage are rooted. Accordingly, by means of the adoption of the complexity system perspective, on the one hand, we underscore the emergent nature of network interactions stemming from the self-organizing …

Barības vielu atkarīgo signālceļu nozīme fenotipiskās atbildes veidošanā adenīna badināšanas laikā maizes rauga šūnās

2017

Šī darba ietvaros noskaidrota TOR un PKA raksturīgo mērķproteīnu - transkripcijas faktoru Gln3p, Msn2p, Msn4p un proteīnkināzes Rim15 iespējamā saistība ar auksotrofās adenīna badināšanas izraisītā paaugstinātā stresa izturības fenotipa veidošanos maizes raugā. Veikta izvēlēto mērķproteīnu sekvenču C-galu saīsināšana un pētīta izveidoto mutanto celmu subletālo stresu (oksidatīvā, karstuma un žāvēšanas) izturība, kā arī novērtēta NADPH/NADP un NADH/NAD attiecība. Secināts, ka visi pārbaudītie TOR un PKA mērķproteīni saistīti ar adenīna badināšanas izraisītajām atbildes reakcijām, apstiprinot barības vielu atkarīgo signālceļu asociāciju ar adenīna badināšanas izraisīto stresa izturības fenoti…

Un balance de la modernización autonómica y las relaciones intergubernamentales

2015

International audience; This article contains an overview of the modernization of the regional administrations since its inception until present. We distinguish roughly four modernizing cycles: the first is mainly identified with the search for legitimacy and survival of the regional administrations. The second is inspired by the New Public Management (NPM) and the emergence of a post-burocratic paradigm that enables the development of new methodologies. The third is characterized by the primacy of e-administration and quality policies applied to public services. Finally, the last cycle poses antagonistic tendencies, according to the outbreak of the current economic crisis.; En este artícul…
