Bronchiektasen und Infekthäufigkeit bei Alpha-1-Antitrypsin-Mangel
1995
UNLABELLED PURPOSE of this study was to determine the prevalence of bronchiectasis in patients suffering from alpha-1-antitrypsin deficiency and to compare its extent with the frequency of infections. MATERIAL AND METHODS High-resolution CT examinations (HRCT) of 23 patients with alpha-1-antitrypsin deficiency were retrospectively assessed for extent, severity and localisation of bronchiectasis, bronchial wall thickening and extent of emphysema. Chest radiographs and clinical records were available for correlation. RESULTS HRCT scans showed bronchiectasis in 14 of 23 patients, bronchial wall thickening in 3/14, and panlobular emphysema in 23/23. Chest radiographs showed bronchiectasis in 4/…
Association of recurrent mutations in BRCA1, BRCA2, RAD51C, PALB2, and CHEK2 with the risk of borderline ovarian tumor.
2021
Abstract Background There are several genes associated with ovarian cancer risk. Molecular changes in borderline ovarian tumor (BOT) indicate linkage of this disease to type I ovarian tumors (low-grade ovarian carcinomas). This study determined the prevalence and association of mutations in BRCA1, BRCA2, PALB2, RAD51C, and CHEK2 with the risk of BOTs. Methods The study group consisted of 102 patients with histologically confirmed BOT and 1743 healthy controls. In addition, 167 cases with ovarian cancer G1 were analyzed. The analyses included genotyping of 21 founder and recurrent mutations localized in 5 genes (BRCA1, BRCA2, PALB2, RAD51C, and CHEK2). The risk for developing BOT and low-gra…
Comparing Recurrent Neural Networks using Principal Component Analysis for Electrical Load Predictions
2021
Electrical demand forecasting is essential for power generation capacity planning and integrating environment-friendly energy sources. In addition, load predictions will help in developing demand-side management in coordination with renewable power generation. Meteorological conditions influence urban area load pattern; therefore, it is vital to include weather parameters for load predictions. Machine Learning algorithms can effectively be used for electrical load predictions considering impact of external parameters. This paper explores and compares the basic Recurrent Neural Networks (RNN); Simple Recurrent Neural Networks (Vanilla RNN), Gated Recurrent Units (GRU), and Long Short-Term Me…
Die chronisch rekurrierende multifokale Osteomyelitis (CRMO)
1998
Chronic recurrent multifocal osteomyelitis (CRMO) is an unusual clinical entity. More than 200 cases are described in the literature and it is presented here with special reference to its radiological aspects. It is an acquired disease of the skeleton which occurs predominantly during childhood and adolescence. About ten per cent of cases begin in early or, rarely, in later adult life. This variant is described here for the first time and is discussed as "adult CRMO". The underlying pathology is a bland, predominantly lympho-plasma cellular osteomyelitis which is self-limiting and leads to bone sclerosis (Garre). It probably involves an abnormal immune process which follows an infection but…
Die Chronisch rekurrierende multifokale Osteomyelitis (CRMO)*: - Teil 2 Klinisch-radiologisch-histopathologische Studie zum kindlich-jugendlichen „Be…
2001
We report about the juvenile and adolescent pelvic type of CRMO in 7 girls and 4 boys. The results show from solitary up to 7 pelvic lesions (average 3 lesions) predominantly in the acetabular and paraacetabular region (sometimes with hip joint effusion as a sign for concomitant coxitis).Tc99m-bone-scan is helpful to evaluate exactly the pattern of bone affection. We find 3 stages of an primarily chronic, non-purulent osteomyelitis going along with a "plasma-cell-sclerotic process", leading to a Garre-type sclerosing end-stage, which probably heals after some years spontaneously, projecting on clinical symptoms and radiological appearance. The concomitant coxitis ("sympathetic coxitis") is …
Azithromycin: Eine anti-inflammatorische Wirksamkeit im Einsatz bei der chronischen rekurrierenden multifokalen Osteomyelitis? Eine vorläufige Mittei…
2000
In this preliminary communication we report our experience with Azithromycin in patients with Chronic Recurring Multifocal Osteomyelitis (CRMO). Seven out of 13 patients, mainly teenager, showed a fast clinical improvement after they were started on Azithromycin. The immediate therapeutic effect of Azithromycin in patients with CRMO was surprising and lead us to the hypothesis that Azithromycin could have an antiphlogistic in addition to it's antibiotic effect in this disease setting. In patients with reactive chronic pelvic osteomyelitis Azithromycin obviously had a direct influence on the sympathic coxitis. Half of the patients reported an immediate reduction of pain and a significant imp…
Salivary levels of Tumour Necrosis Factor-alpha in patients with recurrent aphthous stomatitis
2010
Objetives: Recurrent aphthous stomatitis (RAS) is a common pathology of the oral mucosa with a complex and multifactorial etiology. Tumour Necrosis Factor-alpha (TNF?) is a cytokine with an important but not well-known role in the development of new lesions in RAS patients. Modifications of salivary levels of TNF? in RAS patients during the active periods of the disease have been measured in this work. The possible implication of TNF? in RAS etiology is also discussed. Study design: The study group was composed of 20 patients previously diagnosed with RAS and randomly selected. As a control group 10 healthy patients were also randomly selected. In both groups a TNF? assessment was carried o…
Salivary levels of IgE and ECP in patients with recurrent aphthous stomatitis
2019
Background Recurrent aphthous stomatitis is a common oral mucosa disease, with no specific etiology. Atopy has been implicated in the development of this disease. In this study, the salivary levels of immunoglobulin E (IgE) and eosinophil cationic protein (ECP) were measured as allergy-related biomarkers in patients with aphthous stomatitis. Material and Methods In this case-control study, non-stimulated saliva was collected from 85 participants and IgE and ECP were measured. Data were analyzed in SPSS 20 through the Mann-Whitney test, and p<0.05 was considered significant. Results The salivary levels of IgE and ECP were 1.11±0.65 Iu/ml and 26.93±6.95 ng/ml in the case group and 0.73±0/39 I…
Scialoadeniti ostruttive.Aggiornamento in tema di diagnosi e di terapia
2006
In head and neck district, major salivary gland diseases seem to have a considerable epidemiological and clinical impact, especially in obstructive disease. Major salivary glands, in fact, having a ductal system can develop several diseases: sialoadenitis, sialodochitis and sialoceles. Particularly, the obstructive sialoadenitis, with or without sialolithiasis, are the most frequent inflammatory disorder, especially for submandibular gland. In the clinical practice, the diagnostic approach for obstructive sialoadenitis up to now consisted of traditional Rx, ultrasonographic technique, scintigraphy technique, C.T., sialography technique with contrast or sialography M.R. Since '9O years, lith…
No Reservations Required: Achieving Fairness between Wi-Fi and NR-U with Self-Deferral Only
2021
Wireless technologies coexisting in unlicensed bands should receive a fair share of the available channel resources, even when they use different access methods. We consider the problem of coexistence between Wi-Fi and New Radio Unlicensed (NR-U) nodes, which employ, respectively, a random and scheduled access scheme. The latter typically resorts to reservation signals (RSs), which allow keeping the control of the channel until the start of the next synchronized slot. This mechanism, although effective for increasing the channel access opportunities of scheduled-based nodes, is also a waste of channel resources. We investigate alternative solutions, based on self-deferral only. We built ana…
