We report the case of a patient with multiple empyema present throughout his body, including chronic sinusitis and chronic suppurative otitis media, as well as subsequent epidural empyema, all caused by Streptococcus intermedius. A 38-year-old man presented with chief complaints of headache, left ear discharge, and nasal congestion. Imaging studies revealed pansinusitis, soft tissue signs in the mastoid cells, and otitis media. The patient was treated with meropenem hydrate, 6g/day. While clinical findings indicated improvement of the sinusitis, his headache did not improve...

Perineural catheter infection is a rare but potentially dramatic complication of continuous peripheral nerve block. Different risk factors have been identified and the incidence of infection is increased in trauma victims, intensive care unit patients, immunodeficient individuals, and diabetic patients. Also, postoperative hyperglycemia, the absence of antibiotic prophylaxis, and catheter lasting more than 48 hours seem to be associated with a greater risk of infection. Skin disinfection and a strict aseptic technique during catheter placement are fundamental...

Background: The normal cells derived from human embryonic stem cells (hESCs) are regarded as substitutes for damaged or dysfunctional adult cells. However, tumorigenicity of hESCs remains a major challenge in clinical application of hESC-derived cell transplantation. Previously, we generated monoclonal antibody (MAb) 57-C11 specific to the surface molecule on undifferentiated hESCs. The aim of this study is to prove whether 57-C11-positive hESCs are pluripotent and tumorigenic in immunodeficient mice...

A 10-year-old castrated Domestic Short-Haired cat was presented to a primary care veterinarian for a wellness examination and laboratory examination for monitoring of diabetes mellitus. The CBC revealed marked thrombocytosis, leukopenia and macrocytic, normochromic anemia. The cat tested negative for FeLV and feline immunodeficiency virus, but was positive for Mycoplasma haemominutum by PCR. Hematologic abnormalities were not responsive to therapy, so a repeat CBC and a bone marrow aspiration for cytology were performed...

The role of SRY-related high-mobility-group box (SOX) 12 in leukaemia progression and haematopoiesis remains elusive. This study aimed to examine the expression and function of SOX12 in acute myeloid leukaemia (AML) using human myeloid leukaemia samples and the acute myeloid cell line THP1. Mononuclear cells were isolated from the bone marrow of AML patients and healthy donors. SOX12 expression in haematopoietic cells was evaluated by reverse transcription polymerase chain reaction (RT-PCR). SOX12 short hairpin RNAs (shRNAs) were transduced into THP1 cells, and gene knockdown was confirmed by quantitative RT-PCR and Western blot analysis...

STAT proteins are a family of transcription factors that mediate cellular response to cytokines and growth factors. Study of patients with familial susceptibility to pathogens and/or autoimmune diseases has led to the identification of 7 inherited disorders that are caused by mutations of 4 STAT family genes. Homozygous or compound heterozygous mutations of STAT1 lead to complete or partial forms of STAT1 deficiency that are associated with susceptibility to intracellular pathogens and herpetic infections. Patients with heterozygous STAT1 gain-of-function (GOF) mutations usually present with chronic mucocutaneous candidiasis (CMC) but may also experience bacterial and viral infections, autoimmune manifestations, lymphopenia, cerebral aneurysms, and increased risk to develop tumors...

The skin is colonized by a diverse collection of microorganisms which, for the most part, peacefully coexist with their hosts. Skin and soft tissue infections (SSTIs) encompass a variety of conditions; in immunocompromised hosts, SSTIs can be caused by diverse microorganisms-most commonly bacteria, but also fungi, viruses, mycobacteria, and protozoa. The diagnosis of SSTIs is difficult because they may commonly masquerade as other clinical syndromes or can be a manifestation of systemic disease. In immunocompromised hosts, SSTI poses a major diagnostic challenge, and clinical dermatological assessment should be initially performed; to better identify the pathogen and to lead to appropriate treatment, etiology should include cultures of lesions and blood, biopsy with histology, specific microbiological analysis with special stains, molecular techniques, and antigen-detection methodologies...

Monogenic primary immunodeficiency syndromes can affect one or more endocrine organs by autoimmunity during childhood. Clinical manifestations include type 1 diabetes mellitus, hypothyroidism, adrenal insufficiency, and vitiligo. Lipopolysaccharide (LPS)-responsive beige-like anchor protein (LRBA) deficiency was described in 2012 as a novel primary immunodeficiency, predominantly causing immune dysregulation and early onset enteropathy. We describe the heterogeneous clinical course of LRBA deficiency in two siblings, mimicking an autoimmune polyendocrine disorder in one of them in presence of the same underlying genetic mutation...

Bladder cancer (BC) is the second most common malignancy of the genitourinary system, characterized by the highest recurrence rate of all cancers. Treatment options are limited; thus a thorough understanding of the underlying molecular mechanisms is needed to guide the discovery of novel therapeutic targets. Profilins are actin binding proteins with attributed pleiotropic functions to cytoskeletal remodeling, cell adhesion, motility, even transcriptional regulation, not fully characterized yet. Earlier studies from our laboratory revealed that decreased tissue levels of Profilin-1 (PFN1) are correlated with BC progression to muscle invasive disease...

Mice engrafted with human CD34(+) hematopoietic stem and progenitor cells (CD34(+) -HSPCs) have been used to study human infection, diabetes, sepsis, and burn, suggesting that they could be highly amenable to characterizing the human inflammatory response to injury. To this end, human leukocytes infiltrating subcutaneous implants of polyvinyl alcohol (PVA) sponges were analyzed in immunodeficient NSG mice reconstituted with CD34(+) -HSPCs. It was reported that human CD45(+) (hCD45(+) ) leukocytes were present in PVA sponges 3 and 7 days postimplantation and could be localized within the sponges by immunohistochemistry...

Visceral leishmaniasis (VL) is azooanthroponosis affecting both rural and peri-urban areas, and can also spread into urban areas. Although more than 90% of new cases are reported from six countries: Bangladesh, Brazil, Ethiopia, India, South Sudan and Sudan, VL has emerged in many countries in the world, presenting new cases in new countries of occurrence. Thus, studies concerning epidemiological aspects in different world regions are very meaningful.In this purpose, this study aimed analyze 89 cases of VL, treated between June 2006 and June 2014 at Eduardo de Menezes Hospital (HEM), a Reference Center of Infectious Diseases situated in Belo Horizonte, in Minas Gerais state, Brazil...
