REVIEW
Ferenc Sipos, Györgyi Műzes
Good's syndrome, an infrequent adult-onset immunodeficiency is characterized by the triad of thymoma, hypogammaglobulinemia, and increased susceptibility to recurrent infections. The clinical presentation is highly variable, with a spectrum ranging from recurrent bacterial and opportunistic infections to concomitant autoimmune diseases and, sometimes malignant pathologies. Due to heterogeneous clinical phenotypes and the lack of adequate diagnostic criteria, its recognition is often challenging, even delaying it by years...

Chronic wounds and chronic ulcers are an increasing problem associated with high health care burden and patient burden. The arrested healing of chronic wounds has, in part, been attributed to the presence of biofilms. Substantial research has documented the presence of biofilms in chronic wounds, and many mechanisms of host-pathogen interactions have been uncovered to explain the arrested healing. However, the paradigm of whether biofilms are only observed in chronic infections was recently challenged when biofilms were also observed in acute infections...

Only a few pathologists have the opportunity to verify their personal grading through objective assessment. This study introduces a web-based grading platform to facilitate and validate the grading of renal cell carcinoma and prostate cancer. Two representative images of two clinically annotated cohorts of 100 cases each of prostate and renal cell carcinoma were used. Each participant was asked to grade a tumor series utilizing a three tiered grading system. Finally, a Kaplan-Meier curve was drawn, and the log-rank test was used for statistical testing of the p-value...

Anti-muscarinic type 3 receptor autoantibodies (M3R) and anti-SSA antibodies are both related to salivary secretion. The presence of M3R antibodies in Sjögren's syndrome is previously demonstrated; nevertheless, the relationship between the anti-SSA antibodies and M3R fragment antibodies, namely the N terminal, first, second, and third extracellular loops, remains to be elucidated. In this study, we analyzed the antibodies against the M3R epitopes in healthy controls and anti-SSA antibody-positive connective tissue disease patients through ELISA method...

Bronchial squamous carcinoma in situ (CIS) is a preinvasive lesion that is thought to precede invasive carcinoma. We conducted prospective autofluorescence and white light bronchoscopy trials between 1992 and 2016 to assess the prevalence, molecular markers, and outcome of individuals with CIS and other preneoplastic bronchial lesions. Biopsies were evaluated at multiple levels and selected biopsies were tested for aneuploidy and DNA sequenced for TP53 mutation. Thirty-one individuals with CIS were identified...

Prostate cancer is the world's most frequently diagnosed malignancy in men. Recent work suggests that patients with high ERG expression intensity are significantly more likely to develop biochemical relapse and metastasis, and die of prostate cancer. The objective of this study was to determine the relationship between the intensity of ERG protein expression and the staging of prostate cancer and the formation of metastases in 635 samples. A retrospective cohort analysis was performed using immunohistochemistry reactions in tissue microarray samples taken from non-neoplastic and neoplastic prostate tissue from patients who underwent radical prostatectomies at a reference hospital from 2009 to 2016...

Alzheimer's disease (AD) is an irreversible neurodegenerative disease that affects more than 44 million people worldwide. The pathogenic mechanisms of AD still remain unclear. Currently, there are numerous studies investigating the microbiota-gut-brain axis in humans and rodents indicated that gut microbiota played a role in neurodegenerative diseases, including AD. However, the underlying relationship between the progress of AD disease and the dynamic distribution of gut microbiota is not well understood. In the present study, APPswe /PS1ΔE9 transgenic mice of different ages and sex were employed...

The introduction of direct-acting antiviral (DAA) treatment of hepatitis C virus (HCV) infected patients has greatly increased treatment success rates. However, viral response kinetics to DAA treatment may depend on pre-existing resistance-associated substitutions (RASs) in HCV. The aim of this study was to describe how pre-existing RASs affect DAA treatment-induced reduction in HCV RNA titers in HCV genotypes 1- and 3-infected individuals. Patients with HCV genotype 1 infection (N = 31) treated with either sofosbuvir/ledipasvir/ribavirin or paritaprevir/ombitasvir/ritonavir/dasabuvir/ribavirin and HCV genotype 3-infected patients (N = 16) treated with either sofosbuvir/daclatasvir/ribavirin or sofosbuvir/ribavirin were analyzed...

A total of, 78 Clostridium septicum (CLSE) isolates were screened for genes encoding: α-toxin, flagellin, and resistance to vancomycin (VANg). The isolates were also tested for their ability to form biofilm and their antibiotic susceptibility. All isolates were positive for α-toxin and flagellin genes. However, only 19 isolates (24.3%) showed prevalence for VANg. We observed the strongest capacity to form a biofilm (100%) in isolates from patients with oncologic or septic and febrile diagnoses. This percentage was also very high in patients with colitis and gastrointestinal hemorrhage (72...

Native cardiac valves in the setting of chronic injury may become thickened and disrupted by dystrophic calcification, which impede valve structure/function, and there may be evidence of chondromatous (i.e., cartilaginous, CM) metaplasia admixed with dystrophic calcification. In order to characterize the presence of CM in native cardiac valves - with particular focus upon aortic valves - a retrospective review of the histologic features of 46 native aortic valves (identified from 1094 sequentially reviewed native valves of all types) containing CM were focused upon, as well as correlation with other histopathologic features, and clinical and echocardiographic findings...

Louis Pasteur, born December 27, 1822 in Dole, France, showed in his childhood and youth great abilities as an artistic painter; however by an age of 19, his interest changed toward science, and he moved to Paris to study chemistry and physics at École Normale Supérieure. During graduation, he initiated research on chiral crystallography and stereochemistry and got his doctorates in 1847 in both chemistry and physics. In 1848, he started as high school teacher in Dijon, but shortly after he became a deputy professor at the University of Strasbourg in chemistry and got married to the rector's daughter Marie Laurent...
