Multiple miliary osteoma cutis consists of heterotopic foci of bone tissue in the dermis and subcutaneous tissue. Patients usually present with multiple, asymptomatic facial papules of several millimetres in diameter which cause distress regarding their cosmetic appearance. The condition is described as rare, as only a few cases have been reported since its first description in 1864 by Virchow. We therefore carried out a comprehensive literature search and review, in which 102 published cases were retrieved and analysed...

Here, we report that increasing treatment with inhaled corticosteroids (ICS) in patients with not well-controlled asthma from a medium to a high dose results in a profound reduction of blood eosinophils (median fall in blood eosinophil concentrations from 560 to 320 cells/µL). Therefore, 'normal values' of blood eosinophils in patients with asthma need to be considered in view of the individual ICS doses of the patients. In addition, increases in the dose of ICS may result in blood eosinophil concentrations which would formally preclude treatment with biologics targeting the interleukin-5 pathway...

While athletes are often considered the epitome of health due to their physique and lowered potential for metabolic and cardiovascular diseases, they may also be at risk for the onset and development of venous thromboembolism (VTE). In an attempt to achieve and remain competitive, athletes are frequently exposed to numerous athlete-specific risk factors, which may predispose them to VTE through the disruption of factors associated with Virchow's triad (i.e., hypercoagulability, venous stasis, and vessel wall injury)...

Hemostasis is the normal process of blood coagulation in vivo to stop pathologic bleeding. Virchow triad includes venous stasis, hypercoagulability, and vascular injury. Natural anticoagulants include protein C, protein S, and antithrombin. Factor V Leiden is the most common inherited thrombophilia, followed by prothrombin gene mutation. All inherited thrombophilias are passed down in an autosomal dominant fashion. Patients harboring the antiphospholipid antibodies have an increased risk for thrombosis. von Willebrand disease is the most common inherited bleeding disorder; the pattern of inheritance is autosomal...

Zika virus (ZIKV) has caused substantial concern worldwide owing to its association with severe birth defects, such as microcephaly and other congenital malformations. Inflammasomes, i.e., multi-protein complexes that induce inflammation and pyroptosis, are predicted to contribute to the immune response to this flavivirus. Accordingly, in this study, the in situ inflammasome response was evaluated in fatal cases of ZIKV-linked microcephaly. Brain tissue samples were collected from eight babies, including four ZIKV-positive microcephalic neonates who died after birth and four flavivirus-negative neonatal controls who died of other causes and whose central nervous system (CNS) architecture was preserved...

Venous thromboembolism (VTE), referring to both deep vein thrombosis and pulmonary embolism, is a leading cause of death in the developed world during pregnancy. This increased risk is attributed to the Virchow triad, inherited thrombophilias, along with other standard risk factors, and continues for up to 6 to 12 weeks postpartum. During the peripartum period, women should be risk stratified and preventive measures should be initiated based on their risk. Diagnostic tests and treatment strategies commonly used in VTE differ in pregnancy...

Rudolph Virchow (1821-1902) recognized inflammation in histological preparations of coronary arteries and proposed that inflammation plays a causal role in atherosclerosis. Despite this seminal observation, the main focus of research and drug development programs has been cholesterol alone, and inflammation received less attention over time. However, during the past several decades extensive observations supported the importance of inflammation in the development and destabilization of atherosclerosis. Studies in patients affected by rheumatological diseases suggested an interaction between chronic inflammation and atherosclerotic cardiovascular disease...

The prognostic significance of clinical characteristics and neuroimaging features, especially cranial magnetic resonance imaging (MRI)-based neuroimaging features, in patients with human immunodeficiency virus (HIV)-negative cryptococcal meningitis (CM) has rarely been examined in the literature. We analyzed the clinical characteristics and MRI findings of 65 HIV-negative patients (43 men, 22 women, age 19-86 years) collected during a study period of 15 years (January 2001-December 2015). Their underlying conditions included diabetes mellitus, liver cirrhosis, hematologic disorders, autoimmune disorders, malignancy, chronic obstructive pulmonary disease, adrenal insufficiency and organ transplantation, and their clinical presentations included headache, altered consciousness, fever, seizure, visual disturbance and hearing impairment...

Introduction: In rectal cancer, distal intramural spread may sometimes occur, but a maximum extent of distal spread of > 6 cm is very rare. Case Presentation: A 65-year-old Japanese male with an advanced rectal cancer tumor with para-aortic lymph node metastasis was admitted. We performed a low anterior resection with lymphadenectomy, but the intraoperative frozen-section analysis of margins revealed malignant cell positivity; we, therefore, performed an abdominoperineal resection...

In this manuscript we report the case of a 69-year-old female patient, who suffers from Parkinson's disease (PD) with a dilated Virchow-Robin space (dVRS) on the left anterior perforated substance. During a magnetic resonance imaging examination, the presence of a dVRS was discovered on the left anterior perforated substance. Subsequently, the patient has been subjected to further investigation of magnetic resonance imaging and diffusion tensor imaging (DTI). The DTI data of our PD patient showed increased peak frequency of left fractional anisotropy and decreases in the distribution of Mean Diffusivity(MD) with changes in the fiber density compared to the normal contralateral tract...

The Badimon perfusion chamber is an ex vivo model of thrombosis that assesses the thrombogenicity of blood in humans and large animals. It works with native blood thereby excluding any interfering effects of anticoagulants unavoidable with the majority of platelet function testing methodologies. Each variable of the Virchow's triad (blood, blood flow, and endothelial wall) that modulates blood-vessel wall interaction and thrombus formation is incorporated in this perfusion model. These features make this device a valuable tool for the assessment of thrombogenic potential of various diseases and also gauging the efficacy of antithrombotic (anticoagulant and antiplatelet) treatments...

Salmonella is one of the common causes of food-borne bacterial illnesses. The primary sources of human nontyphoidal Salmonella (NTS) infection are food animals. This study characterized temporally and spatially related Salmonella isolated during April 2013 to March 2014 from faeces of diarrhoeic human patients in Addis Ababa (n = 68) and food animals (n = 84) in Addis Ababa and surrounding districts (dairy cattle, n = 30; slaughtered cattle, n = 20; poultry, n = 26; swine n = 8). Isolates were serotyped, page typed and tested for antimicrobial susceptibility using Kirby-Bauer disc diffusion method, and genotyped by pulsed-field gel electrophoresis (PFGE)...

In this article we examine why Semmelweis's seemingly simple, logical and practical discovery was categorically dismissed by the majority of his contemporaries, and why even many years after his death it was accepted with such reservation. We invoke wherever possible Semmelweis's own words citing from the series of articles appearing in the 'Orvosi Hetilap' [Hungarian Medical Weekly Journal] published in 1858 in Hungary, and also from the German language summary of the Journal published in 1860. We came to the conclusion that although Semmelweis did everything in his power to show the causal relationship between the development of puerperal fever (childbed fever) and some infectious substance on the hands of examining doctors and medical students, this was not convincing enough...

BACKGROUND: Transport of solutes has been observed in the spaces surrounding cerebral arteries and veins. Indeed, transport has been found in opposite directions in two different spaces around arteries. These findings have motivated hypotheses of bulk flow within these spaces. The glymphatic circulation hypothesis involves flow of cerebrospinal fluid from the cortical subarachnoid space to the parenchyma along the paraarterial (extramural, Virchow-Robin) space around arteries, and return flow to the cerebrospinal fluid (CSF) space via paravenous channels...
