Skin infections account for a significant subset of dermatologic conditions of childhood. Common cutaneous viral infections in children include warts, molluscum contagiosum, hand-foot-and-mouth disease, and herpes simplex. Although viral infections are self-limited and often only mildly symptomatic, they can cause anxiety, embarrassment, and health care use. Recognition of their common and atypical presentations is necessary to differentiate them from other skin conditions of similar morphology. Impetigo, cellulitis, and abscess comprise the majority of childhood bacterial skin infections and are treated with topical or systemic antibiotics that cover group A Streptococcus and Staphylococcus aureus...

Fat embolism syndrome presented with the classical triad of respiratory manifestations (95%), cerebral effects (60%) and Petechial rash (33%). Focal neurological symptoms in the form of combined bilateral cortical blindness and motor aphasia even prior to respiratory symptoms have been never reported in previous literature. We describe a case of these rare focal neurological symptoms secondary to the fat embolism syndrome in a young adult male following closed femur fracture.

Marburg virus (MARV), a close relative of Ebola virus, is the causative agent of a severe human disease known as Marburg hemorrhagic fever (MHF). No licensed vaccine or therapeutic exists to treat MHF, and MARV is therefore classified as a Tier 1 select agent and a category A bioterrorism agent. In order to develop countermeasures against this severe disease, animal models that accurately recapitulate human disease are required. Here we describe the development of a novel, uniformly lethal Syrian golden hamster model of MHF using a hamster-adapted MARV variant Angola...

Several mosquito-borne viral infections have recently emerged in North America; West Nile virus is the most common in the United States. Although West Nile virus generally causes a self-limited, flulike febrile illness, a serious neuroinvasive form may occur. Dengue is the most common vector-borne viral disease worldwide, and it has been a significant public health threat in the United States since 2009. Known as breakbone fever for its severe myalgias and arthralgias, dengue may cause a hemorrhagic syndrome...

Haemophagocytic syndrome, or haemophagocytic lymphohistiocytosis (HLH), is a hyperinflammatory disorder characterised by uncontrolled activation of the immune system. It can result from mutations in multiple genes involved in cytotoxicity or occur secondary to a range of infections, malignancies or autoimmune rheumatic diseases. In the latter case, it is also known as macrophage activation syndrome (MAS). Characteristic features are persistent fever, hepatosplenomegaly, petechial/purpuric rash, progressive cytopenias, coagulopathy, transaminitis, raised C reactive protein, falling erythrocyte sedimentation rate, hypertriglyceridaemia, hypofibrinogenaemia and extreme hyperferritinaemia often associated with multi-organ impairment...

We report a case of a 39-year-old healthy male presenting with an eruption consisting of evenly spaced, well-circumscribed, round, petechial macules over a discrete region on his back. A detailed history revealed that the man participated in a high-intensity combination workout routine and post-exercise massage. He reported using a regulation-sized dimpled softball in order to massage the musculature of his back. A diagnosis of traumatic petechiae was established. A growing fitness culture encouraging high-intensity training and post-exercise massage coupled with the high costs of professional masseuse services has led to the increased use of self-massage techniques using both traditional and non-traditional massage equipment...

A young woman was examined in the Emergency Department for fever, pharyngitis and widespread petechial rash. Physical examination, including neurological evaluation, did not show any other abnormalities. Chest X-ray was negative. Blood exams showed leukocytosis and CPR 20 mg/dL (nv<0.5 mg/dL). On the basis of these results and petechial rash evidence, lumbar puncture was performed. CSF was opalescent; physico-chemical examination showed: total proteins 2.8 (nv 0.15-0.45), glucose 5 (nv 59-80), WBC 7600/μL (nv 0-4/ μL)...

Meningococcal meningitis is a well established potential fatal infection characterized by fever, headache, petechial rash, and vomiting in the majority of cases. However, protean manifestations including abdominal pain, sore throat, diarrhea and cough, even though rare, should not be overlooked. Similarly, although disseminated infection could potentially involve various organ-targets, secondary immune related complications including joints or pericardium should be dealt with caution, since they remain unresponsive to appropriate antibiotic regimens...

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening medical emergency which may be difficult to recognize given the wide spectrum in which it presents. A delay in treatment may be catastrophic as untreated cases of TTP have a mortality rate exceeding 90%. Given the high fatality rate of untreated TTP and its range of presenting symptoms, we present our unusual case of TTP in a post-splenectomy patient with early treatment and positive outcome. This case describes a 54-year-old female who presented with hematuria and gingival bleeding, followed by the development of a bilateral lower extremity petechial rash...

Objective. A study to determine if addition of palatal petechiae to Centor criteria adds more value for clinical diagnosis of acute strep pharyngitis in children. Hypothesis. In children, Centor Criteria does not cover all the symptoms and signs of acute strep pharyngitis. We hypothesize that addition of palatal petechiae to Centor Criteria will increase the possibility of clinical diagnosis of group A streptococcal pharyngitis in children. Methods. One hundred patients with a complaint of sore throat were enrolled in the study...

UNLABELLED: Bundibugyo virus (BDBV) is the etiological agent of a severe hemorrhagic fever in humans with a case-fatality rate ranging from 25 to 36%. Despite having been known to the scientific and medical communities for almost 1 decade, there is a dearth of studies on this pathogen due to the lack of a small animal model. Domestic ferrets are commonly used to study other RNA viruses, including members of the order Mononegavirales To investigate whether ferrets were susceptible to filovirus infections, ferrets were challenged with a clinical isolate of BDBV...

BACKGROUND: In this report, we present an interesting case of a patient with Rumpel-Leede phenomenon, a rare occurrence that can result in significant delays in medical treatment. This phenomenon is characterized by the presence of a petechial rash that results from acute dermal capillary rupture. In our patient, it occurred secondary to raised pressure in the dermal vessels caused by repeated inflation of a sphygmomanometer cuff. Contributory factors in Rumpel-Leede phenomenon include prevalent conditions such as diabetes mellitus, hypertension, thrombocytopenia, chronic steroid use, antiplatelets, and anticoagulants...

Children with a petechial rash commonly present to emergency departments. The rash can be associated with serious illnesses, such as invasive meningococcal disease (IMD), but is usually associated with less severe conditions. This article discusses the common and important causes of petechial rash, including IMD, viral illnesses, trauma, Henoch-Schönlein purpura and idiopathic thrombocytopenic purpura. It also analyses the National Institute for Health and Care Excellence (NICE) ( 2014 ) pathway for management of petechial rash in children and examines treatment of the various causes...
