RGB mapping of hemoglobin distribution in skin

2011

An experimental RGB imaging system based on commercial color camera was constructed, and its potential for mapping of hemoglobin distribution in skin was studied. Two types of LEDs (RGB and white “warm” LEDs) were compared as illuminators for acquiring images of vascular and pigmented skin malformations. A novel approach for studies of skin capillary refill by RGB analysis has been proposed and discussed.

First-Episode Psychotic Patients Showed Longitudinal Brain Changes Using fMRI With an Emotional Auditory Paradigm

2020

[EN] Most previous longitudinal studies of functional magnetic resonance imaging (fMRI) in first-episode psychosis (FEP) using cognitive paradigm task found an increased activation after antipsychotic medications. We designed an emotional auditory paradigm to explore brain activation during emotional and nonemotional word processing. This study aimed to analyze if longitudinal changes in brain fMRI BOLD activation is present in patients vs. healthy controls. A group of FEP patients (n = 34) received clinical assessment and had a fMRI scan at baseline and follow-up (average, 25-month interval). During the fMRI scan, both emotional and nonemotional words were presented as a block design. Resu…

A paradigm shift: from disease to health orientation

2006

The history of science has been described as 'paradigm shifts' of sequential overthrow, each new paradigm replacing the previous one. A paradigm is an overarching view-point which guides the articulation of theories and other activities in a particular field. In the exploration of health, two different types of approach can be identified. The pathogenic view, which has dominated the orientation of medicine over the last hundred years, focuses on disease states and underlying factors that modify the chances of entering into one of those states. The competing salutogenic view appears to be undergoing a renaissance in the new strategies of public health and health promotion, and producing theo…

Neural Responses to Musical Rhythm in Chinese Children With Reading Difficulties

2020

The perception of the musical rhythm has been suggested as one of the predicting factors for reading abilities. Several studies have demonstrated that children with reading difficulties (RD) show reduced neural sensitivity in musical rhythm perception. Despite this prior evidence, the association between music and reading in Chinese is still controversial. In the present study, we sought to answer the question of whether the musical rhythm perception of Chinese children with RD is intact or not, providing further clues on how reading and music might be interlinked across languages. Oddball paradigm was adapted for testing the difference of musical rhythm perception, including predictable an…

2019

Since little is known concerning the psychological, cognitive, and neurophysiological factors that are involved in and important for phases of prolonged breath-holding (pBH) in freedivers, the present study uses electroencephalography (EEG) to investigate event-related neurocognitive markers during pBH of experienced freedivers that regularly train pBH. The purpose was to determine whether the well-known neurophysiological modulations elicited by hypoxic and hypercapnic conditions can also be detected during pBH induced hypoxic hypercapnia. Ten experienced free-divers (all male, aged 35.10 ± 7.89 years) were asked to hold their breath twice for 4 min per instance. During the first pBH, a ch…

El uso precoz de la tomografía computarizada en el manejo de la diverticulitis aguda

2007

Objetivo: valorar el uso precoz de la tomografía computarizada (TC) para el diagnóstico, estadificación y manejo de la diverticulitis aguda. Material y métodos: realizamos un estudio prospectivo de 102 pacientes con el diagnóstico clínico de diverticulitis aguda de colon izquierdo. La diverticulitis aguda fue inicialmente dividida en tres estadios. Los pacientes fueron reestadiados en los estadios I, IIa, IIb y III de acuerdo a los hallazgos encontrados en la TC. El diagnóstico se confirmó después intraoperatoriamente, por colonoscopia o estudio con bario. Resultados: fueron incluidos 102 pacientes (52 mujeres y 50 hombres) con una edad media de 59,4 (DS ± 14,96). En 84 (82,35%) paci…

Confocal Laser Endomicroscopy and Chromoendoscopy - A New Option of Surveillance in Patients with Ureterosigmoidostomy or Rectosigmoid Pouch

2010

Purpose In patients with bladder exstrophy-epispadias-complex (BEEC) or in selected patients with bladder loss for other reasons, ureterosigmoidostomy (USIG) & rectosigmoid pouch (Mainz Pouch (MZP) II) has been used at our institution. This diversion carries a lifelong risk for secondary malignancies. Therefore annual colonoscopy is recommended. Identification of potentially malignant structures can be challenging, and biopsies are taken in doubt, with the risk of injuring the ureterocolic implantation site. Using confocal laser endomicroscopy (CLE) and chromoendoscopy, the uretero-intestinal anastomosis is better visualized compared to conventional colonoscopy, and target biopsies could be…

CHF2819: Pharmacological profile of a novel acetylcholinesterase inhibitor

2002

CHF2819 is a novel orally active acetylcholinesterase inhibitor (AChEI) developed for the treatment of Alzheimer's disease (AD). CHF2819 is a selective inhibitor of AChE, it is 115 times more potent against this enzyme than against butyrylcholinesterase (BuChE). Moreover, CHF2819 is more selective for inhibition of central (brain) AChE than peripheral (heart) AChE. In vivo CHF2819, 0.5, 1.5, and 4.5 mg/kg p.o., significantly and in dose-dependent manner increased acetylcholine (ACh) levels in hippocampus of young adult rats. Moreover, aging animals, with lower basal ACh levels than young adult rats, also exhibit a marked increase in hippocampal levels of this neurotransmitter after administ…

Small bowel obstruction after caesarean section: Laparoscopic management. Two case reports

2020

Abstract Introduction Caesarean section is the most common abdominal surgery performed on women worldwide. Adhesions represent a severe complication of cesarean section and can cause different degrees of bowel obstruction. Case reports We report two unusual cases of small bowel obstruction treated with laparoscopic approach after caesarean section performed for gynecological pathologies. In the first one small bowel obstruction was due to volvulus caused by a severe pelvic adhesion syndrome; in the second one, occlusive picture was related to presence of multiple adhesion phenomena between the sigmoid colon and the right ovary as result of abdominal hysterectomy. Discussion The incidence of…
