Trans-visceral migration of retained surgical gauze as a cause of intestinal obstruction: a case report
2008
AbstractIntroductionA retained surgical sponge in the abdomen is uncommon although it is likely that this finding is underreported in the medical literature. The intravisceral migration of retained surgical gauze is even rarer, as demonstrated by the very few cases reported.Case presentationThree years after undergoing anterior resection of the rectum, a 75-year-old man presented with symptoms of small bowel obstruction. Plain abdominal radiography and CT showed a radio-opaque marker; a foreign body was suspected, probably a piece of retained surgical gauze. An ileotomy of about 5 cm. was performed to confirm this diagnosis and remove the gauze.ConclusionAlthough rare, retained gauze in the…
Temporal coherency between receptor expression, neural activity and AP-1-dependent transcription regulates Drosophila motoneuron dendrite development.
2013
Neural activity has profound effects on the development of dendritic structure. Mechanisms that link neural activity to nuclear gene expression include activity-regulated factors, such as CREB, Crest or Mef2, as well as activity-regulated immediate-early genes, such as fos and jun. This study investigates the role of the transcriptional regulator AP-1, a Fos-Jun heterodimer, in activity-dependent dendritic structure development. We combine genetic manipulation, imaging and quantitative dendritic architecture analysis in a Drosophila single neuron model, the individually identified motoneuron MN5. First, Dα7 nicotinic acetylcholine receptors (nAChRs) and AP-1 are required for normal MN5 dend…
Effect of expertise on boundary extension in approach sequences
2017
International audience; In a constantly changing environment, one of the conditions for adaptation is based on the visual system's ability to realize predictions. In this context, a question that arises is the evolution of the processes allowing anticipation with regard to the acquisition of knowledge relative to specific situations. We sought to study this question by focusing on boundary extension, the tendency to overestimate the scope of a previously perceived scene. We presented to novice, beginner, and expert car drivers road scenes in the form of approach sequences constituting very briefly displayed photographs (i.e., 250 milliseconds each), in order to determine the effect of exper…
Case Report: The JAK-Inhibitor Ruxolitinib Use in Aicardi-Goutieres Syndrome Due to ADAR1 Mutation
2021
Type I Interferonopathies comprise inherited inflammatory diseases associated with perturbation of the type I IFN response. Use of Janus kinase (JAK) inhibitors has been recently reported as possible tools for treating some of those rare diseases. We describe herein the clinical picture and treatment response to the JAK-inhibitor ruxolitinib in a 5-year-old girl affected by Aicardi-Goutières Syndrome type 6 (AGS6) due to ADAR1 mutation. The girl's interferon score (IS) was compared with that of her older brother, suffering from the same disorder, who was not treated. We observed a limited, but distinct neurological improvement (Gross Motor Function and Griffiths Mental Development Scales). …
A progressive stage IIIB melanoma treated with oncolytic ECHO-7 virus: A case report
2020
Melanoma is an aggressive skin cancer form with a grave prognosis. Current results suggest that oncolytic virus treatment of melanoma has a high therapeutic potential. ECHO-7 (Rigvir) is the first oncolytic virus registered in Latvia. A female patient was diagnosed with stage IIIB melanoma in December 2012, over 9.4 years ago. After the first excision and re-excision, the patient had several recurrences and disease progressions. After the patient had received surgical treatment in 2014, ECHO-7 virus oncolytic virotherapy was started. Since then, the patient has experienced only one more disease progression episode in May 2015 and has been stable for over 60 months. The patient has not rece…
Direct Evidence for Viral Antigen Presentation during Latent Cytomegalovirus Infection
2021
Murine models of cytomegalovirus (CMV) infection have revealed an immunological phenomenon known as “memory inflation” (MI). After a peak of a primary CD8+ T-cell response, the pool of epitope-specific cells contracts in parallel to the resolution of productive infection and the establishment of a latent infection, referred to as “latency.” CMV latency is associated with an increase in the number of cells specific for certain viral epitopes over time. The inflationary subset was identified as effector-memory T cells (iTEM) characterized by the cell surface phenotype KLRG1+CD127−CD62L−. As we have shown recently, latent viral genomes are not transcriptionally silent. Rather, viral genes are …
Sepsis due to Erysipelothrix rhusiopathiae in a Patient with Chronic Lymphocytic Leukemia Associated with Bronchopneumonia due to PSeudomonas aerugin…
2015
Erysipelothrix rhusiopathiae infections can typically be attributed to exposure to animal products; thus, these infections are more common among farmers, butchers and veterinarians, among others. This article describes a case involving a 54-year-old man who had relative neutropenia subsequent to treatment for chronic lymphocytic leukemia. The patient developed E rhusiopathiae bacteremia with concomitant pneumonia. The author of this article suggests a likely route of infection, which is atypical considering the patient did not report exposure to animal products.
A severe case of Israeli spotted fever with pleural effusion in Italy
2021
Abstract Background The most common Italian rickettsiosis is Mediterranean Spotted Fever (MSF). MSF is commonly associated with a symptom triad consisting of fever, cutaneous rash, and inoculation eschar. The rash is usually maculopapular but, especially in severe presentations, may be petechial. Other typical findings are arthromyalgia and headache. Herein, we describe for the first time an unusual case of Israeli spotted fever (ISF) associated with interstitial pneumonia and pleural effusion in which R. conorii subsp. israelensis was identified by molecular methods in the blood, as well as in the pleural fluid. Case presentation A 72-year-old male presented with a 10-day history of remitt…
Early Diagnosis of Acanthamoeba Infection during Routine Cytological Examination of Cerebrospinal Fluid
2006
ABSTRACT Early identification of Acanthamoeba in cerebrospinal fluid is mandatory to prevent fatal granulomatous amebic encephalitis. In the case presented here amebic trophozoites were detected in a routine cerebrospinal fluid sample. The antibiotic treatment and the apparently low virulence of this isolate were responsible for the benign progression of the infection.
Malassezia restricta Pneumonia in Solid Organ Transplant Recipients: First Report of Two Cases
2021
Emerging fungal infections are a major challenge in solid organ transplantation (SOT) and are associated with high morbidity and mortality. We report two cases of Malassezia restricta pneumonia in SOT recipients. Infections were diagnosed with molecular analysis and histology. Patients were treated with antifungal therapy and have fully recovered.
