CME Sonography 99 Kidney Echo Changes Abstract. Normal kidneys have a smooth contour, kidney length 9-12 cm, volume 90-180 ml/1.73 m2 body surface, parenchyma width 13-18 mm and an echogenicity of the cortex which is hypoechoic compared to the liver and spleen, as well as medullary pyramids, which are again hypoechoic compared to the cortex. Digital ultrasound images enable the echogenicity to be measured between 0 (black) and 255 (white). A normal quotient between the echogenicity of the liver and the renal cortex is 1.0-1.4. A normal quotient between the spleen and the renal cortex is >1.0. The normal quotient between the renal cortex and the renal medulla is >1.0. In diffuse renal parenchyma diseases, changes in echogenicity are observed. There are kidneys with increased echogenicity of the cortex and a ratio to liver and spleen of less then 1.0 and kidneys with hyperechoic renal medulla and the ratio between renal cortex and renal medulla less then 1.0.COVID-19 and Pulmonary Ultrasound An Innovative Approach to the Disease in the GP's Office Abstract. SARS-CoV-2 disease has required significant efforts from treating physicians to adapt their working methods. In a short time, we had to get to know the disease and implement a strategy for patient care. The goal is to provide safe consultation in the office (without contaminating patients), providing an early diagnosis and reproducible follow-up. Lung ultrasound proved to be a safe and reliable method for diagnosing this disease during the pandemic. This article describes the experience gained by treating 116 patients between February 2020 and March 2021.Strong Increase in Lung Ultrasound Due to COVID-19 Abstract. Due to the COVID-19 pandemic, lung ultrasound is experiencing a tremendous upswing and rapid diffusion. This affects both publications and clinical use. The typical changes are described here, also for lung consolidations of other genesis and in interstitial lung diseases. Comparisons with other imaging techniques and indications of the accuracy of lung ultrasound are also presented hereafter.The application of point-of-care lung ultrasound (LUS) in the first diagnosis and management of Corona Virus Disease 2019 (COVID-19) has gained a great interest during a pandemic that is undermining even the most advanced health systems. LUS demonstrated high sensitivity in the visualization of the interstitial signs of the typical pneumonia complicating the infection. However, although this disease gives typical lung alterations, the same LUS signs observed in COVID-19 pneumonia can be detected in other common pulmonary conditions. While being non-specific when considered separately, the analysis of the distribution of the sonographic typical signs allows the assignment of 4 LUS patterns of probability for COVID-19 pneumonia when the whole chest is examined and attention is paid to the presence of other atypical signs. Moreover, the combination of LUS likelihood with the clinical phenotype at presentation increases the accuracy. This mini-review will analyze the LUS signs of COVID-19 pneumonia and how they can be combined in patterns of probability in the first approach to suspected cases.CME Dermatology 23/Answers Hidradenitis suppurativa Abstract. Hidradenitis suppurativa (Acne inversa) is a chronic skin disease characterized by recurrent inflammatory nodules, abscesses, and scarring mainly in the intertriginous areas. The prevalence is estimated to be 0.05 to 4.1 % worldwide, with women being more commonly affected. click here The exact pathogenesis remains unknown, but hair follicle occlusion and inflammation seem to be the initiating events. Several epidemiological correlations with smoking and obesity as well as mutations in gamma secretase genes were described. The therapy depends on the extension of the disorder and should respect the current guidelines. Topical clindamycin is suitable for mild forms of the disease whereas moderate to severe disease requires systemic anti-inflammatory treatment. Surgical intervention is currently the only definitive treatment for hidradenitis suppurativa.Subdural hematomas (SDHs) are increasingly common and can cause ischemic brain injury. Previous work has suggested that this is driven largely by vascular compression from herniation, although this work was done before the era of magnetic resonance imaging (MRI). We thus sought to study SDH-related ischemic brain injury by looking at patterns of cytotoxic edema on diffusion-weighted MRI. To do so, we identified all SDH patients at a single institution from 2015 to 2019 who received an MRI within 2 weeks of presentation. We reviewed all MRIs for evidence of restricted diffusion consistent with cytotoxic edema. Cases were excluded if the restricted diffusion could have occurred as a result of alternative etiologies (e.g., cardioembolic stroke or diffuse axonal injury). We identified 450 SDH patients who received an MRI within 2 weeks of presentation. Twenty-nine patients (∼6.5% of all MRIs) had SDH-related cytotoxic edema, which occurred in two distinct patterns. In one pattern (N = 9), patients presented as comatose with severe midline shift and were found to have cytotoxic edema in the vascular territories of the anterior and posterior cerebral artery, consistent with herniation-related vascular compression. In the other pattern (N = 19), patients often presented as awake with less midline shift and developed cytotoxic edema in the cortex adjacent to the SDH outside of typical vascular territories (peri-SDH cytotoxic edema). Both patterns occurred in 1 patient. The peri-SDH cytotoxic edema pattern is a newly described type of secondary injury and may involve direct toxic effects of the SDH, spreading depolarizations, or other mechanisms.Background Tobacco-smoking in children is one of the most crucial public health concerns, which could be highly prevalent in underprivileged populations. Methods A cross sectional, random sampling survey was conducted to determine the prevalence of current tobacco-smoking and related risk factors among adolescents living in a low-income area of Santiago de Chile. Results Of the 2,747 adolescents participating in the study, 24.0% [95% confidence interval (CI) 22.3-25.5] were current smokers, with no significant difference between girls and boys. Factors associated with current smoking were as follows positive attitude to smoking cigarettes offered by peers [odds ratio (OR) 8.0; 95% CI 5.7-11.3, P  less then  0.001], having smoking best friends (OR 4.0; 95% CI 2.6-6.0, P  less then  0.001), and passive smoking in the house (OR 1.9; 95% CI 1.2-3.1, P = 0.008). A total of 16.8% (95% CI 11.4-18.2) of children had smoked an entire cigarette at the age of ≤12, and 62.3% (95% CI, 60.5-64.1) were passive smokers at home.
