Caveats in interpreting SARS‐CoV‐2 IgM + /IgG − antibody profile in asymptomatic health care workers

2020

Serological testing is increasingly recognized as a useful tool for management of the COVID‐19 pandemic.1 Cross‐sectional serosurveys provide information on exposure levels in a target population, which is helpful for designing public health strategies to blunt community transmission.2 This article is protected by copyright.

Hiperinfección por Strongyloides stercoralis

2010

El Strongyloides stercoralis (Ss) es un nematodo endémico en países de clima tropical y subtropical, y en España se han descrito casos, sobre todo en la costa mediterránea. La infección por Ss suele ser asintomática o manifestarse por síntomas predominantemente digestivos, y en los casos de hiperinfestación produce una estrongiloidiasis diseminada con sobreinfecciones bacterianas sistémicas que provocan una disfunción multiorgánica con resultado letal. Los factores de riesgo más importantes para que una infección en principio intestinal y en muchas ocasiones asintomática adquiera características de gravedad son la inmunosupresión y la utilización de corticoides, por su capacidad de alterar …

Abdominal Tumor in a 14-Year-Old Adolescent: Imperforate Hymen, Resulting in Hematocolpos—A Case Report and Review of the Literature

2014

Background. Abdominal masses in female adolescents are uncommon. A rare cause of this condition is hematocolpos due to imperforate hymen.Case. We present a case of an unusually massive asymptomatic abdominal bulk in a 14-year-old female patient, who sought for medical advice after unusual abdominal pain lasting for few weeks. The patient was otherwise asymptomatic, apart from an unusual dramatic expansion of her abdominal wall during the last month. We describe the surgical management and the follow-up of the patient.Summary and Conclusion. Clinicians should keep in mind that an imperforate hymen can cause abdominal growth due to hematocolpos and include it in the differential diagnosis of …

Motor asymmetry attenuation in older adults during imagined arm movements

2014

International audience; Laterality is an important feature of motor behavior. Several studies have shown that lateralization in right-handed young adults (i.e., right versus left arm superiority) emerges also during imagined actions, that is when an action is internally simulated without any motor output. Such information, however, is lacking for elderly people and it could be valuable to further comprehend the evolution of mental states of action in normal aging. Here, we evaluated the influence of age on motor laterality during mental actions. Twenty-four young (mean age: 24.7 +/- 4.4 years) and 24 elderly (mean age: 72.4 +/- 3.6 years) participants mentally simulated and actually execute…

New insights into symptomatic or silent atrial fibrillation complicating acute myocardial infarction

2015

International audience; Atrial fibrillation (AF) is the most frequent heart rhythm disorder in the general population and contributes not only to a major deterioration in quality of life but also to an increase in cardiovascular morbimortality. The onset of AF in the acute phase of myocardial infarction (MI) is a major event that can jeopardize the prognosis of patients in the short-, medium- and long-term, and is a powerful predictor of a poor prognosis after MI. The suspected mechanism underlying the excess mortality is the drop in coronary flow linked to the acceleration and arrhythmic nature of the left ventricular contractions, which reduce the left ventricular ejection fraction. The p…

Laparoscopic treatment of a large pedunculated hemangioma of the liver: a case report

2016

Hepatic hemangiomas are the most common benign tumors of the liver, often asymptomatic and discovered incidentally. A 62-year-old woman was referred to our Institution under the suspicion of having an 8 cm-sized GIST. Due to the atypical features of the lesion on TC scan, a biopsy was performed. We report the case of pedunculated hepatic hemangioma with the aim to discuss the diagnostic approach, the possible causes of misdiagnosis and the opportunity of the laparoscopic approach.

Frontal Electroencephalogram Alpha Asymmetry during Mental Stress Related to Workplace Noise

2021

This study aims to investigate the effects of workplace noise on neural activity and alpha asymmetries of the prefrontal cortex (PFC) during mental stress conditions. Workplace noise exposure is a pervasive environmental pollutant and is negatively linked to cognitive effects and selective attention. Generally, the stress theory is assumed to underlie the impact of noise on health. Evidence for the impacts of workplace noise on mental stress is lacking. Fifteen healthy volunteer subjects performed the Montreal imaging stress task in quiet and noisy workplaces while their brain activity was recorded using electroencephalography. The salivary alpha-amylase (sAA) was measured before and immedi…

Relationship between endothelial dysfunction, intima media thickness, hypertension and other cardiovascular risk factors in asymptomatic subjects

Coexpression of vasoactive intestinal peptide, calcitonin gene-related peptide and substance P immunoreactivity in parasympathetic neurons of the rhe…

1995

Abstract By the use of light microscopic immunohistochemistry, the present study investigates whether substance P (SP) and calcitonin generelated peptide (CGRP), which are well documented neurotransmitter candidates in primary sensory fibers, are also expressed in parasympathetic neurons of the rhesus monkey lung. A combination of double fluorescence immunohistochemistry and staining of adjacent sections revealed triple coexistence of SP, CGRP and the cholinergic co-transmitter vasoactive intestinal peptide (VIP) in a large number of neuronal cell bodies in intrinsic peribronchial ganglia. In addition, there was co-localization of SP and CGRP in choline acetyltransferase (ChAT)-positive neu…

Pre- and postsynaptic effects of muscarinic agonists in the guinea-pig ileum

1980

The effects of several muscarinic agonists on smooth muscle (postsynaptic effect) and on acetylcholine release (presynaptic effect) were compared in the longitudinal muscle-myenteric plexus preparation of the guinea-pig ileum. 1. For release experiments the acetylcholine stores of the preparation were labelled with 3H-choline. Electrical field stimulation in the absence of a cholinesterase inhibitor caused an outflow of tritium that reflected release of 3H-acetylcholine. The agonists oxotremorine, arecaidinepropargylester, methylfurmethide, muscarine, carbachol, arecoline and pilocarpine inhibited the stimulation-induced outflow in a concentration-dependent manner. At the highest concentrat…
