Mapping of the perigastric lymphatic network using indocyanine green fluorescence imaging and tissue marking dye in clinically advanced gastric cance…
2022
Abstract Background Using indocyanine green (ICG) fluorescence imaging and tissue marking dyes (TMDs), perigastric lymphatic mapping and their pathological correlation were examined to see whether ICG staining covers all metastatic lymph nodes (LNs) in advanced gastric cancer (AGC). Methods Patients with AGC who underwent open distal or total gastrectomy were enrolled. ICG was serially injected intraoperatively into the subserosa along the greater and lesser curvatures. Stomach specimens were examined under a near-infrared camera. ICG-stained LNs were named, excised, and tattooed with different colored TMDs to retrace the exact location after pathological examinations. Results A total of 68…
Conservative treatment of ectopic pregnancies using a single echo-guided injection of methotrexate into the gestational sac
1991
The authors describe the possibility of the conservative treatment of five early ectopic pregnancies. A single injection of methotrexate into the tubal gestational sac was performed under vaginal ultrasound guidance. In all five cases, a clear ectopic gestational sac could be visualized. The pregnancies dated from the 5th to the 7th week of amenorrhea. Strict ultrasound follow-up following injection showed a gradual reduction in the size of the tubal gestational sac. At the same time, plasma beta-hCG gradually decreased to zero after a maximum time period of 25 days. Subsequent hysterosalpingography performed on all of the women demonstrated bilateral normal patent tubes. It is concluded th…
Expresión proteica de p53 y proliferación celular en leucoplasias orales
2005
Objetivos: Conocer la expresión proteica de las alteraciones genéticas que se producen en las etapas precoces de la cancerización del campo de cavidad oral en nuestro medio. Estudiar la proliferación celular mediante Ki-67 y la expresión de la proteína p53 para valorar si las alteraciones en la expresión proteica de estos marcadores suceden de forma secuencial a través de las distintas etapas en la cancerización del campo de la cavidad oral. Material y métodos: Se realizó un estudio mediante técnicas de inmunohistoquímica sobre 53 pacientes que presentaron lesiones de leucoplasia oral, atendidos por el Servicio de O.R.L del Hospital Universitario de Salamanca, desde 1.990 hasta 2000. Se inc…
“Near-TME”: proposed standardisation of the technique for proctectomy in male patients with ulcerative colitis
2022
Abstract Background The aim of the present study was to describe in detail an approach to proctectomy in ulcerative colitis (UC), which can be standardized; near-total mesorectal excision (near-TME), to prevent injuries to autonomic pelvic nerves and subsequent sexual dysfunction. Methods We demonstrate the technique ex vivo on a cadaver from a male patient in lithotomy position and on a sagittal section of a male pelvis. We also demonstrate the technique in vivo in two male patients diagnosed with UC, with no history of sexual dysfunction or bowel neoplasia. The study was performed at the Human Embryology and Anatomy Department. University of Valencia, Spain. Results The posterolateral dis…
Neuropsychological performance 10 years after immunization in infancy with thimerosal-containing vaccines
2009
OBJECTIVE. Thimerosal, a mercury compound used as a preservative in vaccines administered during infancy, has been suspected to affect neuropsychological development. We compared the neuropsychological performance, 10 years after vaccination, of 2 groups of children exposed randomly to different amounts of thimerosal through immunization. METHODS. Children who were enrolled in an efficacy trial of pertussis vaccines in 1992–1993 were contacted in 2003. Two groups of children were identified, according to thimerosal content in vaccines assigned randomly in the first year of life (cumulative ethylmercury intake of 62.5 or 137.5 μg), and were compared with respect to neuropsychological outcome…
Effect of duration of breastfeeding on neuropsychological development at 10 to 12years of age in a cohort of healthy children
2012
Aim The aim of this article was to explore the effect of duration of breastfeeding on neurocognitive development. Method The long-term effect of breastfeeding on neurodevelopment was examined through a battery of neuropsychological tests in 1403 children (693 females, 710 males; mean age 11y 9mo [SD 6mo], range: 10y 3mo-12y 8mo) who were originally recruited at 6 to 12weeks of age for a clinical trial on acellular pertussis vaccines. An estimated IQ was obtained from scores of the vocabulary, similarities, block design, and coding tests. Breastfeeding data had been prospectively collected throughout the first year of life. Duration of exclusive breastfeeding was defined as the time during w…
Thimerosal induces calcium mobilization, fructose 2,6-bisphosphate synthesis and cytoplasmic alkalinization in rat thymus lymphocytes
1991
The effect of thimerosal on intracellular calcium ([Ca2+]i), pH (pHi) and fructose 2,6-bisphosphate (Fru 2,6-P2) in thymus lymphocytes was investigated. The effect of thimerosal on cell growth was also examined. Thimerosal produced a dose-dependent increase in [Ca2+]i, pHi and in the level of fructose 2,6-bisphosphate. Thimerosal was, however, unable to produce cell proliferation and inhibited [3H]thymidine incorporation when cells were challenged with PHA and costimulator. In the absence of external calcium, thimerosal produced only a slight increase in [Ca2+]i. In Na(+)-containing buffer, thimerosal induced an initial acidification (0.05 +/- 0.01 pH units), followed by an alkalinization o…
Effectiveness and Safety of Ustekinumab in Ulcerative Colitis: Real-world Evidence from the ENEIDA Registry
2021
Abstract Background and Aims The development programm UNIFI has shown promising results of ustekinumab in ulcerative colitis [UC] treatment which should be confirmed in clinical practice. We aimed to evaluate the durability, effectiveness, and safety of ustekinumab in UC in real life. Methods Patients included in the prospectively maintained ENEIDA registry, who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score [PMS]>2], were included. Clinical activity and effectiveness were defined based on PMS. Short-term response was assessed at Week 16. Results A total of 95 patients were included. At Week 16, 53% of patients had response [including 35% o…

Vengon considerate tre fonti: il papiro "Arciduca Ranieri"(III sec. a.C.) contenente sette versi, con notazione melica, dell'antistrofe del primo stasimo dell'Oreste (408 a.C.) di Euripide; la Stele di Sicilo (I/II sec. d. C.); il trittico fiammingo (1460 circa) di Roger van der Weyden, conservato nel duomo di Polizzi Generosa, nella cui tavola centrale quattro angeli – attorno alla Madonna in trono con Gesù bambino – stanno eseguendo il mottetto "Ave regina coelorum, mater regis angelorum" del compositore inglese Walter Frye: due cantano e due suonano.
