Reference interval of monocyte distribution width (MDW) in healthy blood donors.
2020
Abstract Background The aim of the study was to accurately establish the reference interval (RI) of monocyte distribution width (MDW) in healthy blood donors by the direct method using different statistical approaches. Methods MDW was measured in 486 subjects. RI of MDW was calculated by the non-parametric method, the robust method and, the Harrell-Davis bootstrap method and using different tests to identify potential outliers (Dixon-Reed and Tukey). Results Lower and upper reference limits of the RI calculated by the non-parametric method were, 16.22 (90%CI 15.78–16.47) – 23.15 (90%CI 22.80–24.10) (without outlier removal), and 16.44 (90%CI 16.21–16.67) – 22.99 (90%CI 22.33–23.22) (after o…
Normal values for fundus perimetry with the MAIA microperimeter and short-term repeatability evaluation
2016
National audience; Purpose To assess retinal sensitivity by means of microperimetry and to evaluate the intersession fluctuation using the MAIA microperimeter in healthy volunteers. Methods Prospective, monocentre study. Fifty‐six healthy volunteers (age range, 20–80 years), underwent an automatic, full‐threshold microperimetry of the central field (custom grid, area of 10° in diameter, 37 stimulated points), with the MAIA microperimeter (CenterVue, Padova, Italy). A subgroup of 24 subjects was retested after 1 h (test 2) and 1 week (test 3) to determine the repeatability of the technique. A subgroup of 22 subjects was also tested on the OPKO microperimeter (Optos, Dunfermline, Scotland) (a…
Sonographic biometry of liver and spleen size in childhood.
1983
In 194 healthy children of all ages, sonographic measurements of the liver and spleen were performed on standardized section planes and normal values established. These measurement values showed an approximately linear increase in the course of development and correlated best with the body length. For a rapid orientational evaluation of the liver size, sonographic nomograms of the individual measurements were developed. The spleen size was determined by volume calculation. On the basis of an index of liver size, which was calculated from the individual measurements, a diagram for simultaneous determination of liver and spleen size could be developed. These nomograms permit objective morphom…
Normal values of M mode echocardiographic measurements of more than 2000 healthy infants and children in central Europe
2000
OBJECTIVE—To obtain normal M mode (one dimensional) echocardiographic values in a substantial sample of normal infants and children. DESIGN—Data were obtained over three years from a single centre in central Europe. PATIENTS—2036 healthy infants and children aged one day to 18 years. METHODS—In line with recommendations for standardising measurements from M mode echocardiograms, and using digital echocardiographic equipment, measurements were obtained of the following: right ventricular anterior wall thickness at end diastole, right ventricular end diastolic dimension, thickness of interventricular septum at end diastole and end systole, thickness of posterior wall of the left ventricle at …
Study between anb angle and Wits appraisal in cone beam computed tomography (CBCT)
2013
Objectives: To analyse the ANB and Wits values and to study correlations between those two measurements and other measurements in diagnosing the anteroposterior maxilo-mandibular relationship with CBCT. Study Design: Ninety patients who had previously a CBCT (i-CAT®) as a diagnostic register were selected. A 3D cephalometry was designed using one software package, InVivo5®. This cephalometry included 3 planes of reference, 3 angle measurements and 1 linear measurement. The means and standard deviations of the mean of each measurement were assessed. After that, a Pearson´s correlation coefficient has been performed to analyse the significance of each relationship. Results: When classifying t…
Analysis of LDL and HDL size and number by nuclear magnetic resonance in a healthy working population: The LipoLab Study
2020
Background and aim Atherosclerosis is the underlying process in cardiovascular disease (CVD), the first cause of death in developed countries. We aimed to identify people with no known CVD and normal values of LDL-C and HDL-C, but with alterations in the number and size of lipoprotein particles (as measured by nuclear magnetic resonance [NMR]) and to analyse their sociodemographic, clinical and biochemical characteristics. Methods Cross-sectional study in occupational risks prevention centre in Castellon (Spain) in 2017 and 2018, in consecutively recruited adults (18-65 years) with no known CVD. Sociodemographic, clinical and biochemical variables were collected. Lipid profiles were analyse…
The behaviour of OKT3-, OKT4- and OKT8-positive cells during phases of elevated spontaneous chemiluminescence activity (CL-A) in multiple sclerosis p…
1987
The chemiluminescence activity (CL-A; synonym = burst activity, BA) and the percentage of OKT3-, OKT4- and OKT8-positive peripheral blood cells were serially examined in four control persons and in eight patients with multiple sclerosis. When the OKT values obtained in phases of increased CL-A (clinical remission) were compared with those of the control group, the percentage of OKT3-positive cells was reduced (P = 0.014), and that of OKT4-positive cells increased (P = 0.014); there were no significant changes in the percentage of OKT8-positive cells (P = 0.171). After the CL-A had returned to normal values, the OKT4-positive cells remained elevated (P = 0.029), whereas the OKT3- (P = 0.342)…
Posterior interosseous nerve of the elbow at the arcade of Frohse: Ultrasound appearance in asymptomatic subjects
2019
PURPOSE To assess the normal values of the antero-posterior (AP) diameter of the posterior interosseous nerve (PIN) of the elbow as it passes beneath the arcade of Frohse and to search for PIN-diameter differences between the upstream, entry point and downstream of the arcade. MATERIAL AND METHODS Thirty asymptomatic patients prospectively underwent bilateral B-mode ultrasound of the PIN of the elbow. There were 15 men and 15 women with a mean age of 30.2±5.31 (SD) years (range: 26-43 years). Of these, 23 patients were right-handers (23/30; 77%) and 7 were left handers (7/30; 23%). AP diameter of the PIN was measured in long axis at three different locations including the entry point of the…
Assessment of various factors influencing esophageal pressure measurement. II. Significance of physiological factors in intraluminal manometry.
1980
In the second part of this study the effect of age, sex, body size, body weight and timing of the manometric examination (morning vs. noon) on esophageal pressure measurement was investigated in a total of 119 healthy subjects, using an electromagnetic microtransducer. Additionally intraindividual variation of pressures was studied over a period of 6 months. Of these parameters only age influenced upper esophageal sphincter (UES) pressure significantly: The mean UES pressure of younger subjects (20-49 years) was significantly higher (144.4 +/- 8.6 mmHg) compared to that of older subjects (50-80 years) where a mean pressure of 103.4 +/- 7.2 mmHg was recorded (p less than 0.0005). Intraindivi…
Massive triiodothyronine intoxication: Efficacy of hemoperfusion?
2002
A case of massive accidental triiodothyronine intoxication (1000-fold the usual therapeutic dose, for 8 days) is reported with important disturbances of cardiovascular and central nervous systems that required intensive care support. Serum free triiodothyronine levels were 4789 pmol L-1 on admittance (normal values, 3.5-6.5 pmol L-1). In the absence of a specific treatment, hemoperfusions were performed but failed to accelerate significantly the decay of blood levels of free triiodothyronine (apparent half-life 25.9 hours; 95% confidence interval: 19.8-37.4 hours). The patient, a young woman, made a satisfactory recovery, in spite of important clinical complications.
