Gastric metastasis from breast cancer

2020

Introduction: Breast carcinoma is the most common malignancy in women and the main cause of tumor deaths. Despite early recognition by screening and improvement in treatment regimens, many patients will eventually develop metastases, either locoregional recurrences or distant metastases, most frequently in the skeleton, liver and lung. Metastases to the gastrointestinal tract are infrequent and not even mentioned in the major oncologic textbooks. Case presentation: We report a case of metastasis to the stomach from occult breast cancer. The diagnosis was established by computed tomography (CT), histologic and immunohistochemical analyses of biopsies of the stomach lesion. The patient was tr…

Understanding the microbial biogeography of ancient human dentitions to guide study design and interpretation

2021

AbstractThe oral cavity is a heterogeneous environment, varying in factors such as pH, oxygen levels, and salivary flow. These factors affect the microbial community composition and distribution of species in dental plaque, but it is not known how well these patterns are reflected in archaeological dental calculus. In most archaeological studies, a single sample of dental calculus is studied per individual and is assumed to represent the entire oral cavity. However, it is not known if this sampling strategy introduces biases into studies of the ancient oral microbiome. Here, we present the results of a shotgun metagenomic study of a dense sampling of dental calculus from four Chalcolithic i…

Mandibular metastasis from carcinoma of the bladder: Report of a case and literature review

2022

Metastases represent about 1% of all malignant tumors of the oral region. Only 12 cases of metastases to the jawbones and 3 to the oral soft tissues from a carcinoma of the bladder are reported in the English literature. Here we report a case of an 86 year-old man with a metastasis to the anterior region of the lower jaw from a transitional cell carcinoma of the bladder treated 5 years before, all-together with a literature review.

Metastatic tumors to the jaws: A report of eight new cases

2006

Purpose: The purpose of the article is to present 8 new cases of metastatic tumors occurring in the jawbones, their clinical features , diagnostic workup and management. Patients and methods: The records of 8 patients with metastatic jaw lesions were reviewd. Demographic data, presenting symptoms, primary tumor site, radiographic findings, bone scintigraphy , histopathology and clinical management were analyzed. Results: The patients , ranged in age from 44 to 80 years, with a mean of 64.5 years. The primary malignant sites were: the lung , the breast , the rectum, the thyroid, the uterus and the parotid gland . The mandible was the site of oral involvement in seven cases and the maxilla in…

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…

Specyfika języka finansów na przykładzie terminologii stosowanej w strategiach inwestycyjnych

2018

W artykule zostaje podjęta próba przedstawienia istoty języków specjalistycznych. Jako że samo pojęcie języków specjalistycznych jest bardzo złożone i definiowane w zależności od przyjętych kryteriów, w pierwszej części referatu przedstawiona będzie krótka ich charakterystyka, a następnie omówiona zostanie specyfika jednego spośród nich, a mianowicie języka finansów. Jak niemal każdy również język finansów jest dość rozbudowanym systemem obejmującym zarówno teksty mówione (również istotne są tu teksty niewerbalne), jak i pisane. Do grupy tych ostatnich zalicza się akty prawne, zapisy notowań, analizy i komentarze do nich, teksty ogólne dotyczące np. giełdy. Dla celów niniejszego artykułu wy…

Marine Invertebrates as Bioindicators of Heavy Metal Pollution

2015

The marine environment presents a range of anthropogenic contaminants. According to the World Health Organization, more than 100,000 chemicals are released into the global environment every year as a consequence of their production, use and disposal. The fate of a chemical substance depends on physical-chemical properties, in combination with the characteristics of the environment where it is released. Among the substances that accumulate in the sea, for anthropogenic activities, metals/metalloids have a leading position. Some of these have a biological role but their bioaccumulation is injurious. Chemical pollutants can cause effects on organisms, biodiversity and human health. Various eff…

UV Metal Semiconductor Metal Detectors. A Robust Choice for (Al,Ga)N Based Detectors

2004

UV detection is interesting for combustion optimization, air contamination control, fire and solar blind rocket launching detection. Most of these applications require that UV detectors have a huge dynamic response between UV and the visible, and a very low dark current in the range of the UV flux measured. (Al,Ga)N alloys present a large direct bandgap in this range and therefore can be used as an active region in such detectors. To take advantage of the large Schottky barrier, the good alloy quality, and to avoid any doping problems, we have developed MSM photodetectors. High quality material has been grown with MOCVD and MBE on sapphire substrates. Stress management is employed for alumi…
