Perichondritis and auricular cellulitis related to piercings as first manifestation of monkeypox / Pericondritis y celulitis auricular relacionadas con piercings como primera manifestación de viruela del mono

Introduction: Pinna infections are usually due to Staphylococcus aureus infection. It is common for the patient to have had an earring in the area of infection. Monkeypox infection has gone from being an endemic infection to a worldwide health emergency. Case summary: In this article we present five cases of monkeypox earring infection of the pinna and what common features we have seen that differentiate them from Staphylococcus aureus infection. Discussion: Symptoms of monkeypox include general malaise, fever with uni- or bilateral lymphadenopathy, and then the appearance within one or two days of skin lesions, we want to alert he otolaryngologist and the medical society to the possibility the diagnostic possibility of monkeypox in patients with an auricular perichondritis.(AU)

Introducción: Las infecciones del pabellón auricular se deben habitualmente a la infección por Staphilococcus Aureus. Es habitual que el paciente se haya realizado un pendiente en la zona de la infección. La infección por viruela del Mono ha pasado de ser una infección endémica a una emergencia sanitaria a nivel mundial. Caso: Exponemos en este artículo cinco casos de infección del pabellón auricular por pendiente por viruela del mono y que características comunes hemos visto que las diferencian de la infección por Staphilococcus Aureus. Discusión:Los síntomas de la viruela del mono incluyen malestar general, fiebre con linfadenopatía uni o bilateral, y posteriormente la aparición en uno o dos días de lesiones cutáneas, queremos alertar al otorrinolaringólogo y a la sociedad médica de la posibilidad diagnóstica de viruela del mono en pacientes con una pericondritis auricular.(AU)

Assessment of the perception of vertical subjectivity in children born preterm.

Children born preterm have increased rates of paediatric mortality and morbidity. Prematurity has been associated with impaired visual perception and visuo-motor integration. The alteration of the perception of verticality translates into alterations of the vestibular system at central and/or peripheral level, which may manifest itself in symptoms such as imbalance, dizziness or even vertigo. The aim of this study was to compare subjective visual vertical (SVV) test scores in children born preterm with those of children born at term at ages between 7 and 10. One hundred ten children with no neurodevelopmental disorder of 7 to 10 years of age were studied using a mobile application on a smartphone attached to a wall by means of a rotating plate. The SVV test was compared between two groups: a group of 55 preterm children (53 very preterm children born under 32 weeks of gestational age and 2 preterm with very low birth weight) and another group of 55 children born at term (after 37 weeks of gestational age). The SVV results were analysed for comparison with respect to prematurity, sex and age. We found no significant differences in the SVV study in the comparison between preterm and term children. In addition, no significant differences were observed regarding sex or age between 7 and 10 years.  Conclusion: We found no alterations in the perception of vertical subjectivity in children between 7 and 10 years of age, with antecedents of very preterm birth and/or very low birth weight. What is Known: • The different studies published so far suggest the existence of balance disorders in premature children, although in most of these studies the children are examined at an age when the vestibular system is not mature and with non-specific tests for the study of the vestibular system. What is New: • We compared the results of the subjective visual vertical (SVV) test in a group of 55 preterm children (53 very preterm children born under 32 weeks of gestational age and 2 preterm with very low weight at birth) and in a group of 55 children born at term (after 37 weeks of gestational age), at the ages of 7 to 10 years and observed no differences. • We conclude that, if there had been any vestibular alterations due to very premature birth, these must have been compensated by the age of 7.

Test-retest of the Subjective Visual Vertical Test performed using a mobile application with the smartphone anchored to a turntable.

PURPOSE: The alterations of the Subjective visual vertical test are related to vestibular pathology. Our previously validated method to distinguish between healthy and pathological individuals measures the deviation from the Subjective visual vertical using a mobile application installed on a smartphone fixed to a turntable anchored to the wall. The aim of this study was evaluating the intra-observer reliability of our method in individuals with or without vestibular pathology. METHODS: Participants were recruited consecutively. In each individual two measurements with an interval of 2 h were made. Both tests were performed by the same examiner. A total of 91 patients were included in this study, of which 25 were healthy and 66 diseased. Intra-observer reliability was evaluated using the intraclass correlation coefficient (ICC). To assess the clinical accuracy of the measurement, we calculated the standard error of the measurement (SEM) and the minimum detectable change (MDC) with a 95% confidence interval. RESULTS: Intra-observer reliability was excellent with an ICC 0.95 (0.92-0.97) in the whole sample, in healthy patients 0.91 (0.80-0.96) and in pathological patients 0.92 (0.87-0.95). The SEM was calculated to be 0.59 for the whole sample (0.26 in the "healthy" group, and 0.67 in the pathological group). Likewise, the sample's MDC was 1.16, being 0.52 and 1.36 for the healthy and the pathological group, respectively. CONCLUSIONS: Considering the results, our method presents an excellent intraobserver reliability. Furthermore, changes in deviation greater than 0.52 in healthy individuals and 1.36 in pathological individuals can be considered a real change in deviation.

Efficacy of the subjective visual vertical test performed using a mobile application to detect vestibular pathology.

BACKGROUND: The subjective visual vertical (SVV) test is a sensitive test of vestibular dysfunction that allows the evaluation of otolithic organs; however, with the current method, there are technical and logistical limitations that make the application of this test difficult in the conventional clinic. OBJECTIVE: The objective of this study is to assess the effectiveness of detecting vestibular pathology using the SVV via a new screening method. METHODS: A consecutive sample of 62 patients with suspected vestibular pathology was included in the study. The patients were clinically diagnosed according to the Barany Society criteria. An exploratory system was designed using a mobile application in Android that detects accelerometer oscillations and involves placing the smartphone on a rotating disk anchored to the wall. All patients underwent a SVV examination using the bucket method and the study test. A cut-off point of the ROC curve was calculated for each test, and its sensitivity, specificity, diagnostic accuracy and probability ratios for detecting vestibular pathology were analysed. The SVV results were compared using the bucket test and the study test. RESULTS: We observed significant differences in sensitivity between the two tests: 86.95% for the study test versus 67.4% for the bucket test (p < 0.01). In the ROC curve, an area under the curve of 0.90 was observed for the study test, with a cut-off of 2.43 for a sensitivity of 86.95% and a specificity of 93.75%. CONCLUSIONS: SVV testing using a smartphone placed on a rotating disk anchored to the wall offers greater diagnostic accuracy than SVV using the bucket test. Both methods are inexpensive, harmless and easily accepted by patients.
