Systematic analysis of esophageal pressure topography in high-resolution manometry of 68 normal volunteers
2013
Summary The introduction of high-resolution manometry (HRM) has been a significant advance in esophageal diagnostics. Normative values however are currently based upon a single set of published reference values, and multiple new metrics have been added over the past several years. Our goal was to provide a second set of ‘normal-values’ and to include all current metrics suggested by the 2012 Chicago classification. Sixty-eight subjects without foregut symptoms or previous surgery (median age 25.5 years, ranging from 20–58 years, 53% female) underwent esophageal motility assessment via an established standardized protocol. Normative thresholds were calculated for esophago-gastric junction (E…
Button batteries and typical swallowed foreign bodies can be differentiated in high-resolution X-Rays.
2021
Abstract Background Button battery ingestions have emerged as an increasing medical issue in recent years, especially for children. The frequent use of these energy sources in small appliances and toys is responsible for their ubiquitous occurrence in households. In addition to other possible foreign bodies, button batteries are particularly dangerous as they can cause severe complications in the aerodigestive tract. Objective The study aimed for a detailed analysis of specific radiographic identifiers of button batteries and similarly configured potential esophageal foreign bodies in high-resolution X-ray scans. Methods A selection of potentially hazardous button batteries - in cases of in…
Hochauflösende Dünnschicht-CT zum präoperativen Staging beim Rektumtumor: Vergleich mit der endo-luminalen Sonographie und der Histologie
1990
Rectal carcinomas are amongst the most common malignant tumours. The aim of this work was to determine whether high resolution CT with thin sections (1 mm) can provide satisfactory delineation of perirectal tumour infiltration. Correct determination of local tumour spread was possible in four out of nine patients and distinction between those tumours confined to the rectal wall and those infiltrating the perirectal tissues was possible in four out of eight patients.
Intravaskuläre Sonographie: Erste klinische Ergebnisse
1991
Intravascular ultrasound is a new diagnostic modality which, for the first time, provides high resolution images of the vessel wall. 91 intraluminal ultrasound studies were performed in 50 patients during the course of 55 diagnostic and therapeutic catheterizations. A F-6 ultrasound catheter (20 MHz) was used. The method is an easily and rapidly performed addition to angiography. Changes in vessel walls (arteriosclerosis, dissection, tumour infiltration) can be readily diagnosed and their extent can be accurately described. The ability to determine luminal cross sectional area is particularly helpful for planning and performing therapeutic interventions.
Prevalence and Risk Factors for Anal Human Papillomavirus Infection in Human Immunodeficiency Virus–Positive Men Who Have Sex with Men
2018
A correction has been published:The Journal of Infectious Diseases, Volume 218, Issue 8, 15 October 2018, Page 1350, https://doi.org/10.1093/infdis/jiy315; International audience; Background:We assessed prevalence and risk factors for anal human papillomavirus (HPV) in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM), who are at high-risk of HPV-related anal cancer.Methods:APACHES is a multicentric, prospective study of anal HPV infection and lesions in HIV-positive MSM aged ≥35 years. At baseline, participants underwent anal swabs for HPV and cytology, plus high-resolution anoscopy. High-risk HPV (HR-HPV) was tested by Cobas4800, with genotyping of HR-HPV positiv…
HIGH-RESOLUTION ULTRASONOGRAPHY (HRUS) OF THE MENISCAL CYST OF THE KNEE : OUR EXPERIENCE
2007
Purpose. This study was undertaken to assess the diagnostic accuracy of high-resolution ultrasonography (HRUS) in the detection of meniscal cysts. Materials and methods. Over a 2-year period, 1,857 patients underwent magnetic resonance imaging (MRI) of the knee for traumatic or degenerative disorders. All patients with MRI evidence of a meniscal cyst were studied by HRUS. HRUS was also performed on an equal number of patients without MRI evidence of meniscal cyst who were used as a control group. All HRUS examinations were conducted by a radiologist blinded to the MRI findings. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of HRUS were assesse…
Beyond Hunting Camps: Early Holocene Occupations in High Cantabrian Mountains (Spain)
1998
En la comunicación se presentan los resultados de las excavaciones en el abrigo de La Calvera (Camaleño, Cantabria) incluyendo un conjunto de nuevas dataciones radiocarbónicas y se hace una reflexión sobre la ocupación de las montañas cantábricas al comienzo del Holoceno. In the communication the results of the excavations in La Calvera rock shelter (Camaleño, Cantabria) are presented, including a set of new radiocarbonic dates and a reflection is made on the occupation of the Cantabrian mountains at the beginning of the Holocene.
Mitochondrial function and sirtuin expression in hippocampus of young and old high- and low-capacity runner rats
2016
Introduction: Exercise and aerobic capacity are associated with improved learning in animals and humans. The hippocampus is a brain structure involved in learning and memory. High rates of neurogenesis have been shown to take place in the dental gyrus of hippocampus in response to physical exercise. It is not known whether mitochondrial dysfunction in the hippocampus is responsible for decline in cognitive function associated with low fitness level and aging, and whether intrinsic aerobic capacity is a risk factor for it. Methods: Mitochondrial function was investigated in the hippocampi of young and old highcapacity runner (HCR) and low-capacity runner (LCR) rats using high-performance res…
Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory
2017
We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to $80^\circ$ and energies in excess of 4 EeV ($4 \times 10^{18}$ eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional informa…
Legal nature of the Supreme Court resolutions
2020
Przedmiotem opracowania jest charakter prawny uchwał Sądu Najwyższego. Charakter ten jest sporny w doktrynie. W tym zakresie występują trzy odmienne stanowiska. Według jednego z nich „uchwały Sądu Najwyższego są orzeczeniami”. Drugie stanowisko przyjmuje, iż „uchwały Sądu Najwyższego stanowią odrębną grupę orzeczeń, nie są jednak orzeczeniami sądu, które dotyczą przedmiotu procesu, ponieważ nie rozstrzygają wprost o jego przedmiocie”. Trzeci kierunek głosi, że „uchwały Sądu Najwyższego, wydawane na podstawie art. 441 § 1 k.p.k., rozstrzygające zagadnienia prawne, nie należą do kategorii orzeczeń”. Przeprowadzone rozważania w niniejszym artykule prowadzą zatem do konkluzji, że uchwały Sądu N…
