Subcutaneous Single Injection Digital Block with Epinephrine
The aim of this study was to investigate the anesthetic effect and risk of epinephrine for subcutaneous single injection digital block. Either 3.0 mL 1.0% Lidocaine or a 3.0 mL 1.0% Lidocaine with (1 : 100,000) epinephrine was injected into the subcutaneous space at the middle point of the palmar digital crease of the 18 middle fingers of 9 healthy volunteers.
The SpO2 of the fingers decreased to a maximum of 97. No subjects showed any symptoms of ischemic injury. The time to anesthesia for the fingers was significantly shorter (P < 0.05), and the duration of anesthesia was significantly longer (P < 0.01) for the fingers in the epinephrine group. In conclusion, a subcutaneous single injection digital blocks with 3.0 mL of 1.0% Lidocaine and (1 : 100,000) epinephrine were safe, reducing the time to the onset of anesthesia, while also markedly prolonging the anesthesia
Management of Natural History collections: criteria and parameters of evaluation
[ES] Las colecciones de historia natural son una herramienta básica para la investigación
científica y el estudio de la distribución en el pasado de muchas especies, así como de
la propia historia de la ciencia. Además del uso científico de estas colecciones, destacan
otros como el histórico, el divulgativo-pedagógico y el estético. De ahí la importancia
que tiene una gestión eficaz de las mismas, la cual implica diversos aspectos, que van
desde la conservación y su mantenimiento, su inventario, ordenación y procesamiento
informático hasta las múltiples tareas relacionadas con su uso en consultas, visitas,
préstamos científicos y participación en actividades de carácter divulgativo. En este
artículo se examinan los criterios para evaluar la gestión de las colecciones de historia
natural y se definen una serie de parámetros, útiles para medir el estado de una colección
y su evolución en el tiempo, tanto en su crecimiento como en su uso, principalmente. Se
ejemplifica todo ello en el grupo de los poliquetos, del que el Museo Nacional de Ciencias
Naturales de Madrid (MNCN) cuenta con una estimable colección, y se comparan los
resultados, según varios parámetros seleccionados, con los de otras colecciones de
poliquetos de diversas instituciones de todo el mundo.[EN] Natural History collections are a basic and essential tool for scientific research,
the study of the distribution in the past of many species of animals and plants and the
History of Science. As well as the scientific aspect of these collections, stand outs other
uses as the historic one, the educational and the aesthetic. All these are reasons that
show the importance of an effective management of the Natural History collections as
well as the several tasks related to it, as consults, visits, scientific loans and educational
activities. In this article various criteria and useful parameters are provided for evaluating
the curatorial state of a Natural History collection and its evolution, both in growth
and use mainly. Finally, an example based on the Polychaeta, an estimable group in
the Invertebrates Collection of the Museo Nacional de Ciencias Naturales of Madrid
(MNCN), is provided. The results of several selected parameters are compared with
other Polychaeta collections from several institutions around the world.Peer reviewe
RAYNAUD'S SYNDROME IMPROVED BY THE INTRAVENOUS ADMINISTRATION OF A THROMBOXANE SYNTHETASE INHIBITOR
A 66-year-old man with multiple cerebral infarctions was treated with
sodium ozagral ; this was associated with an improvement in his Raynaud's syndrome
attributable to vibration-induced white finger disease. Sodium ozagrel selectively inhibits
thromboxane synthetase, reducing thromboxane A₂ (TXA₂) and also slightly increasing
prostacyclin (PGI₂) ; this leads to vasodilatation and the inhibition of platelet aggregation.
An imbalance between TXA₂ and PGI₂ caused by vascular endothelial injury is thought to
cause Raynaud's phenomenon. Sodium ozagrel appears to improve the symptoms of
Raynaud's syndrome by relatively increasing PGI₂, thus correcting the imbalance. Ozagrel,
which currently is being used to treat cerebral thrombosis and bronchial asthma, as well as
to improve vasospasm following subarachnoid hemorrhage, also may provide effective
relief in patients with Raynaud's syndrome
Novel haemodialysis (HD) treatment employing molecular hydrogen (H2)-enriched dialysis solution improves prognosis of chronic dialysis patients: A prospective observational study
Abstract Recent studies have revealed unique biological characteristics of molecular hydrogen (H2) as an anti-inflammatory agent. We developed a novel haemodialysis (E-HD) system delivering an H2 (30–80 ppb)-enriched dialysis solution by water electrolysis, and conducted a non-randomized, non-blinded, prospective observational study exploring its clinical impact. Prevalent chronic HD patients were allocated to either the E-HD (n = 161) group or the conventional HD (C-HD: n = 148) group, and received the respective HD treatments during the study. The primary endpoint was a composite of all-cause mortality and development of non-lethal cardio-cerebrovascular events (cardiac disease, apoplexy, and leg amputation due to peripheral artery disease). During the 3.28-year mean observation period, there were no differences in dialysis parameters between the two groups; however, post-dialysis hypertension was ameliorated with significant reductions in antihypertensive agents in the E-HD patients. There were 91 events (50 in the C-HD group and 41 in the E-HD group). Multivariate analysis of the Cox proportional hazards model revealed E-HD as an independent significant factor for the primary endpoint (hazard ratio 0.59; [95% confidence interval: 0.38–0.92]) after adjusting for confounding factors (age, cardiovascular disease history, serum albumin, and C-reactive protein). HD applying an H2-dissolved HD solution could improve the prognosis of chronic HD patients

<p>Time course of changes in the Defined Daily Dose of anti-hypertensive agents in the two groups is shown. Each treatment group was further divided into two groups at DDD baseline levels; those of DDD = 0 (43 cases in E-HD, 31in C-HD), and those of DDD >0 (97 cases in E-HD, 91 in C-HD). In cases of DDD = 0, there was a significant change in C-HD, while, no change was found in E-HD, respectively (repeated-measure ANOVA). In cases of DDD >0, there was a significant change in E-HD, while, no change was found in C-HD, respectively (repeated-measure ANOVA). *P<0.001. **P<0.05.
